Objective To evaluate the clinical efficacy of dragon-tiger contending needling at Xi-cleft points plus electroacupuncture in treating postherpetic neuralgia (PHN).Method Seventy PHN patients were randomized into a treatment group of 36 cases and a control group of 34 cases. The treatment group was intervened by dragon-tiger contending needling at Xi-cleft points plus electroacupuncture, while the control group was treated with electroacupuncture alone. In the 4-week treatment, the Visual Analogue Scale (VAS) scores right before and after the 1st, 2nd, 6th, 9th and 12th treatment sessions were recorded, “the maximum pain intensity since the last treatment session” and “real-time analgesic effect” were observed, and the total therapeutic efficacy was also evaluated.Result The real-time analgesic effects right after the 1st, 2nd and 6th treatments in the treatment group were significantly better than those in the control group (P<0.05). The “maximum pain intensities since the last treatment session” prior to the 2nd, 6th, 9th, and 12th treatment sessions were significantly different from the pain intensity before the intervention in the two groups (P<0.05). The “maximum pain intensities since the last treatment session” prior to the 6th, 9th, and 12th treatment sessions were significantly different from those in the control group (P<0.05). The total effective rate and recovery plus markedly-effective rate were respectively 97.2% and 77.8% in the treatment group, versus 91.2% and 59.2% in the control group. There was a statistically significant difference in the recovery plus markedly-effective rate between the two groups (P<0.05).Conclusion Dragon-tiger contending needling at Xi-cleft points plus electro- acupuncture is an effective approach in treating PHN; it acts efficiently and can produce a satisfactory real-time analgesic effect.

BACKGROUND:The sclerotic zone in the femoral head is an important imaging feature in the progression of steroid-induced femoral head necrosis,which is associated with disease prognosis.Peroxisome proliferator-activated receptor γ coactivator 1α(PGC-1α)has been shown to possess biological activities such as osteogenesis,angiogenesis and anti-mitochondrial apoptosis,which may be closely related to bone repair of steroid-induced femoral head necrosis. OBJECTIVE:To screen for the differential proteins in the sclerotic zone of steroid-induced osteonecrosis of the femoral head versus the normal zone,to screen for hub proteins in the sclerotic zone,and to verify the differential expression of hub proteins in the femoral head specimens following steroid-induced femoral head necrosis,and to to explore the repair pattern of the sclerotic zone following steroid-induced femoral head necrosis. METHODS:Femoral head samples were collected from patients with steroid-induced osteonecrosis of the femoral head receiving total hip arthroplasty.The differentially expressed genes in the sclerotic zone and the normal zone were screened by Tandem Mass Tags and analyzed by GO and KEGG signaling pathways to construct a protein-protein interaction network and screen hub genes.In addition,the expression of hub genes in the sclerotic zone was verified by immunohistochemistry and western blot. RESULTS AND CONCLUSION:Quantitative protein profiling by Tandem Mass Tags revealed that 609 proteins were significantly differentially expressed(Log2FC＞1.20,Log2FC＜0.84 and P＜0.05)in the sclerotic zone of the femoral head compared with the normal zone,of which 290 proteins were upregulated and 319 proteins were downregulated.The GO and KEGG pathway enrichment analyses revealed that among the top 10 enriched pathways,Wnt signaling pathway and life-cycle regulatory pathway were closely related to bone repair;in the life-cycle regulatory pathway,PGC-1α was one of the important proteins.In addition,western blot results verified the low expression of PGC-1α and NRF1 in the sclerotic zone and high expression of Cleaved Caspase-3 in the sclerotic zone compared with the normal zone of steroid-induced femoral head necrosis specimens.Light microscopic immunohistochemical results showed the distribution of PGC-1α,NRF1 and Cleaved Caspase-3 positive expression in the sclerotic and normal zones in the femoral head tissue specimens,indicating the presence of their expression in bone trabeculae,osteoblasts and bone marrow.In contrast,the brown area of the sclerotic zone of femoral head necrosis stained darker and showed more obvious expression of Cleaved Caspase-3.To conclude,in the sclerotic zone of steroid-induced femoral head necrosis,biological behaviors including activation of osteogenesis-related pathways such as Wnt and oxidative apoptosis characterized by low expression of PGC-1 are observed.Low expression of PGC-1α in the sclerotic zone of steroid-induced femoral head necrosis may be associated with the activation of oxidative apoptosis.

Objective:To explore the impact of intradialytic hypotension (IDH) on brain component volume, as well as its relationship with depression and cognitive function changes in maintenance hemodialysis patients.Method:It was a cross-sectional observational study. Clinical data of 119 patients under maintenance hemodialysis in Peking Union Medical College Hospital from July 2013 to July 2014 were collected, retrospectively. Patients were divided into IDH group and non-IDH group. 3.0T Magnetic resonance imaging examination of the head for all patients was completed and the results of volume analysis of each component of the brain were extracted. Cognitive function was assessed by the Chinese version of the simplified mental state examination scale (C-MMSE) and the Chinese version of the Montreal cognitive assessment scale (C-MoCA). Depressive status was assessed by the Hamilton depression scale 17 (HAMD_17) and living ability was assessed by the Alzheimer's disease collaborative study-daily living ability assessment questionnaire. In addition, the Philadelphia word learning test was used to measure memory, the Boston naming test to measure language, the connection test A and B to measure executive ability, and the Stroup test C to measure attention. The differences in brain component volume, cognitive function, emotion, and life ability between two groups of patients were compared, and the correlation between IDH and brain component volume was explored by regression analysis.Result:A total of 119 patients were included in this study, of whom 22 (18.5%) had hypotension during dialysis. The volumes of amygdala, cuneiform lobe, and posterior cingulate gyrus in IDH group were significantly smaller than those in the non-hypotension group [ (1.6±0.2) mm 3vs. (1.7±0.2) mm 3, t=2.674, P=0.009; (6.9±0.8) mm 3vs. (7.4±1.0) mm 3, t=2.187, P=0.031; (6.9±0.8) mm 3vs. (7.4±0.9) mm 3, t=2.252, P=0.024]. The differences of gray matter, white matter volume between the two groups showed a similar trend but did not reach statistical significance. And lacunar infarction and cerebral microbleeds were more common in IDH group. The daily living ability scores of the two groups were similar (65.51±11.52 vs. 65.71±11.53, Z=-0.456, P=0.648). The proportion of patients with cognitive abnormalities was higher in the IDH group, without statistical significance. The proportion of depression was similar. Univariate linear regression analysis showed that IDH was significantly negatively correlated with the volume of amygdala, cuneiform cortex, and posterior cingulate gyrus, which control emotions in the brain ( B=-0.117, 95% CI -0.203--0.030, P=0.009; B=-0.484, 95% CI -0.923--0.046, P=0.031; B=-0.485, 95% CI -0.911--0.058, P=0.026). After multivariate adjustment, decreased amygdala volume was still correlated with IDH ( B=-0.111, 95% CI -0.198--0.025, P=0.026). Conclusion:Recurrent IDH may lead to atrophy of various brain components, which may be one of the reasons for cognitive and emotional changes in maintenance hemodialysis patients.

Hemophilic arthritis(HA),caused by recurrent bleeding,can seriously affect patient quality of life and consumes extensive social and medical resources.There is thus a need to establish an animal model of HA for research;however,this is limited by ethical requirements.Here we review the recent literature and summarize research progress into animal models of HA at home and abroad,from the aspects of species selection,modeling method,histopathology,and imaging evaluation method.Species selection includes rodents such as mice,New Zealand rabbits,beagles,miniature pigs,and crab-eating macaques.Modeling method comprise gene knockout trauma models,gene knockout spontaneous models,and injection models.Among these,the gene knockout spontaneous model closely mimics the pathological process of spontaneous bleeding and concurrent arthritis in human HA,making it more relevant to human HA.However,due to high modeling costs,phenotypic instability,and low survival rates,this model is not the preferred choice for animal experimental studies.In contrast,gene knockout trauma models exhibit characteristics such as short modeling time,strong stability,and high success rates,thus being widely utilized in animal experimental research.Evaluation of HA models involves various imaging method including MRI,micro-CT,MSKUS/PD,in addition to various gross scoring method.By reviewing the progress of HA model research,more experimental evidence is provided for investigating the pathogenesis and validating the efficacy of HA treatments,thereby compensating for the lack of clinical data,particularly in the field of traditional Chinese medicine therapy.

Objective To explore the anti-inflammatory effect of Qingre Jiedu(QRJD)formula on mice with gout and its effect on gut microbiota.Methods Forty C57BL/6 mice weighing 20～22 g were divided into control(CON),model(MOD),allopurinol(ALLO),and QRJD formula(QRJD)groups,and i.g.10 g/0.1 mL carboxymethyl cellulose was administered to the CON every morning from 1 to 35 days.A hyperuricemia mouse model was prepared by intragastric injection of a potassium oxalic acid(500 mg/kg)and yeast extract(10 g/kg)suspension.On day 29,50 μL sterile carboxymethyl cellulose was injected into the right ankle of mice in the CON group under isoflurane-induced anesthesia,and a gouty arthritis model was prepared by injecting the same volume of sodium urate(50 mg/mL)into the right ankle of mice in the other groups.Each group was treated with corresponding drugs every day.On day 35,samples were collected from mice that had been fasted for 6 hours without water.Blood indexes,such as uric acid,creatinine,and urea nitrogen,were assessed.Hematoxylin-eosin and saffranine O-fast green staining was performed on ankle joints.Anti-inflammatory indexes of interleukin-10(IL-10)and transforming growth factor-β1(TGF-β1)were detected by ankle joints immunohistochemical assay.The cecum contents of mice were collected,and changes in gut microbiota were analyzed by high-throughput sequencing of 16S rDNA.Results(1)After 7 days of treatment,compared with the MOD group,QRJD formula effectively reduced the blood concentrations of uric acid(P＜0.001),creatinine(P＜0.01),and urea nitrogen(P＜0.05),and effectively protected renal functions.(2)Compared with the MOD group,HE staining showed that synovial hyperplasia and inflammatory cell infiltration were reduced in the QRJD formula group after treatment.The cartilage arrangement of the compound was more orderly than before,cartilage destruction was less than that in the MOD group,and no matrix loss was observed.(3)Immunohistochemical analysis of the ankle joint indicated that IL-10 and TGF-β1 were not significantly increased in CON and MOD groups.Compared with the MOD group,IL-10 and TGF-β1 expression in the QRJD formula group were increased(P＜0.05).(4)In terms of biodiversity,the number of MOD-specific OTUs increased by 75 compared to the CON group,while the QRJD was able to reduce the number of MOD-specific OTUs to more closely resemble the CON group;no significant difference was found in α-diversity among the four groups(P＜0.05),whereas β-diversity was more similar to the CON group(P=0.001).(5)Compared with the CON group,the MOD group exhibited increased abundances(P＜0.05)of Ruminococcaceae spp.,Dubosiella sp.,Tyzzerella sp.,Ileibacterium sp.,and Bacteroidales spp..In contrast to the MOD group,the QRJD formula group showed elevated abundances(P＜0.05)of Lactobacillus sp.,Ligilactobacillus sp.,and Bacteroides sp..Furthermore,an interaction network of gut microbiota indicated mutual interactions among these microorganisms.(6)In the correlation analysis between gut microbiota and renal functions as well as anti-inflammatory factors,the relative abundances of Dubosiella sp.,Tyzzerella sp.,and Bacteroidales spp.were significantly positively correlated to SUA and SCR(P＜0.05).However,Lactobacillus sp.,Ligilactobacillus sp.,and Mitochondria spp.exhibited a positive correlation to anti-inflammatory factors IL-10 and TGF-β1 with a more significant association observed for TGF-β1(P＜0.05).(7)COG function prediction suggested that the functions of the QRJD formula group were concentrated on inorganic ion transport and metabolism,and carbohydrate transport and metabolism.Conclusions QRJD effectively modulates immune inflammation and gut microbiota dysbiosis,thereby treating gout.Its mechanism of gout prevention and treatment may involve regulation of gut microbiota diversity and abundance,as well as the control of the abundance of differential bacterial species,such as Ruminococcaceae spp.,Dubosiella sp.,and Lactobacillus sp.,to achieve gout therapy.

BACKGROUND:Piezo1,a mechanosensitive protein,is tightly connected to osteogenic differentiation,and it has been demonstrated that TAZ has a role in regulating osteogenic differentiation.It is unclear whether TAZ participates in the regulation of osteogenic differentiation of human bone marrow mesenchymal stem cells by Piezo1,so it is crucial to investigate its unique mechanism to prevent osteonecrosis of the femoral head. OBJECTIVE:To elucidate what function Piezo1 plays in osteogenic differentiation and TAZ expression in human bone marrow mesenchymal stem cells. METHODS:The siRNA targeting Piezo1 was constructed and transfected into 293T cells.The silencing efficiency was detected by RT-qPCR.The selected Piezo1-Home-2337 was packaged according to the silencing efficiency,and its optimal multiplicity of infection value was assayed by immunofluorescence staining.The packaged Piezo1 silencing recombinant lentivirus was transfected into human bone marrow mesenchymal stem cells,and its silencing effect was detected by RT-qPCR and western blot assay.Alizarin red staining,alkaline phosphatase activity analysis,immunofluorescence staining,RT-qPCR and western blot assay were utilized to analyze the effect of silencing Piezo1 on the osteogenic differentiation of human bone marrow mesenchymal stem cells. RESULTS AND CONCLUSION:(1)The mRNA and protein levels of Piezo1 in human bone marrow mesenchymal stem cells transfected by si-Piezo1 were decreased significantly,with a statistically significant difference compared with normal and negative control groups.(2)The alkaline phosphatase activity in the si-Piezo1 group was much lower and the calcium deposition in the si-Piezo1 group was significantly reduced compared with the negative control group.(3)The mRNA levels of osteogenesis-related genes including Runt-related transcription factor 2(Runx2),osteopontin(OPN),distal-less homeobox 5(DLX5),osteocalcin,β-catenin and Tafazzin(TAZ)in the si-Piezo1 group were significantly decreased compared with the negative control group.Afterward,the expression levels of TAZ and β-catenin protein in the si-Piezo1 group were down-regulated significantly compared with the negative control group,whereas the expression levels of p-TAZ and p-β-catenin protein in the si-Piezo1 group had the opposite condition.(4)The results of immunofluorescence staining showed that the expression of TAZ and β-catenin in human bone marrow mesenchymal stem cells in the si-Piezo1 group was less compared with the negative control group.(5)These findings indicate that Piezo1 can promote the osteogenic differentiation of human bone marrow mesenchymal stem cells.The osteogenic ability of human bone marrow mesenchymal stem cells is significantly reduced after silencing Piezo1,and the expression of TAZ is also reduced.

BACKGROUND:Compound Shengmai Chenggu capsule has good therapeutic effects on early steroid-induced osteonecrosis of the femoral head,but the exact mechanism of treatment is not fully understood. OBJECTIVE:To observe the effect of compound Shengmai Chenggu capsule on fucosyltransferase 8,osteogenic gene and Wnt/β-catenin in bone tissue of rats with steroid-induced osteonecrosis of the femoral head. METHODS:Sixty Sprague-Dawley rats were randomized into blank group,model group,low-,middle-,and high-dose drug groups(n=12 per group).In the latter four groups,animal models of steroid-induced osteonecrosis of the femoral head were established by subcutaneous injection of imiquimod(once every 2 weeks,2 times in total)and gluteal muscle injection of methylprednisolone(once a week,4 times in total).The low-,middle-and high-dose drug groups were given 1.89,3.78 and 7.56 g/kg per day compound Shengmai Chenggu capsule solution by gavage respectively on the second day after the last modeling.The same amount of saline was given by gavage to the model group.Administration lasted 8 weeks.After the administration,micro-CT scan,histological staining,compression test,RT-qPCR and western blot were performed on the femoral head. RESULTS AND CONCLUSION:Micro-CT scan results showed that compared with the blank group,trabecular volume fraction,trabecular number and trabecular thickness were significantly decreased(P<0.05),while trabecular separation was increased in the model group(P<0.05).Compared with the model group,the compound Shengmai Chenggu capsule could increase trabecular volume fraction,trabecular number and trabecular thickness(P<0.05),and decrease trabecular separation(P<0.05)in a dose-dependent manner.Hematoxylin-eosin staining results showed that compared with the model group,the rate of empty bone lacunae was reduced in a dose-dependent group in the low-,middle-,and high-dose compound Shengmai Chenggu capsule groups(P<0.05).Immunohistochemical staining results showed that compared with the blank group,the protein expression of fucosyltransferase 8,Runx2 and bone morphogenetic protein 2 was reduced in the model group(P<0.05);compared with the model group,the compound Shengmai Chenggu capsule increased the protein expression of fucosyltransferase 8,Runx2 and bone morphogenetic protein 2 in a dose-dependent manner(P<0.05).Results from the compression test showed that there was a dose-dependent increase in the maximum load and elastic modulus of the femoral head in the low-,middle-,and high-dose compound Shengmai Chenggu capsule groups compared with the model group(P<0.05).RT-qPCR and western blot results showed that the mRNA and protein expressions of fucosyltransferase 8,Runx2,alkaline phosphatase,osteocalcin,osteoblast-specific transcription factor and bone morphogenetic protein 2 were decreased in the model group compared with the blank group(P<0.05);compared with the model group,there was a dose-dependent increase in the mRNA and protein expressions of the above indicators in the low-,middle-,and high-dose compound Shengmai Chenggu capsule groups compared with the model group(P<0.05).Compared with the blank group,the mRNA and protein expression of Wnt2,low-density lipoprotein receptor-related protein 5 and β-catenin were decreased(P<0.05)and the mRNA and protein expressions of glycogen synthase kinase 3β were increased(P<0.05)in the model group;compared with the model group,there was a dose-dependent increase in the mRNA and protein expressions of Wnt2,low-density lipoprotein receptor-related protein 5 and β-catenin(P<0.05)but a dose-dependent decrease in the mRNA and protein expressions of lycogen synthase kinase 3β(P<0.05)in the low-,middle-,and high-dose compound Shengmai Chenggu capsule groups.To conclude,the mechanism by which the compound Shengmai Chenggu capsule treats steroid-induced osteonecrosis of the femoral head may activate the Wnt/β-catenin signaling pathway through the up-regulation of fucosyltransferase 8,thereby promoting bone formation.

BACKGROUND:The majority of studies on developmental dysplasia of the hip focus on hip malformations,but there are few reports on the effects of acetabular dysplasia on the spine. OBJECTIVE:To investigate the compensation of spinopelvic parameters in coronal and sagittal views in patients with developmental dysplasia of the hip,and to explore the correlation between acetabular development and spinopelvic parameters. METHODS:A total of 101 patients with developmental dysplasia of the hip admitted to the Third Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2018 to June 2022 were selected as the trial group,and 114 healthy subjects were selected as the control group during the same period.The spinopelvic parameters of the subjects were measured through the full-length X-ray films of the coronal and sagittal spines:lumbar lordosis,anterior pelvic tilt,thoracolumbar kyphosis,Cobb angle,and the distance between the C7 plumb line and the center sacral vertical line,sacral slope,pelvic incidence,and thoracic kyphosis.The differences in spinopelvic parameters were compared between the two groups.In addition,the differences in spinopelvic parameters in patients with unilateral,bilateral and different Crowe classifications of developmental dysplasia of the hip were compared.Pearson correlation analysis was used to explore the correlation between Sharp angle and spinopelvic parameters. RESULTS AND CONCLUSION:(1)In the sagittal view,the lumbar lordosis in the trial group was significantly lower than that in the control group(P<0.05).The pelvic tilt and kyphosis angle of the thoracolumbar segment in the trial group were significantly greater than those in the control group(P<0.05).In the coronary position,the Cobb angle and the distance between the C7 plumb line and center sacral vertical line in the trial group were significantly greater than those in the control group(P<0.05).There was no significant difference in the remaining spinopelvic parameters between the two groups(P>0.05).(2)The lumbar lordosis of patients with bilateral developmental dysplasia of the hip was significantly lower than that of patients with unilateral developmental dysplasia of the hip(P<0.05).The pelvic tilt,thoracolumbar kyphosis,Cobb angle and the distance between the C7 plumb line and center sacral vertical line in bilateral developmental dysplasia of the hip patients were significantly greater than those in unilateral developmental dysplasia of the hip patients(P<0.05).(3)The lumbar lordosis decreased with the increase of Crowe classification severity(P<0.05).The pelvic tilt increased with the severity of the Crowe classification(P<0.05).(4)Pearson correlation analysis showed that Sharp angle was negatively correlated with lumbar lordosis(P<0.05),while Sharp angle was positively correlated with anterior pelvic tilt,Cobb angle,C7 plumb line and center sacral vertical line(P<0.05).(5)It is concluded that the pelvic tilt,thoracolumbar kyphosis,Cobb angle and the distance between the C7 plumb line and center sacral vertical line increase,while lumbar lordosis decreases in developmental dysplasia of the hip patients.The degree of acetabular dysplasia was significantly correlated with lumbar lordosis,pelvic tilt,Cobb angle,C7 plumb line and center sacral vertical line.

BACKGROUND:The gluteus medius not only abducts the hip joint,but also plays an important role in limiting the external movement of the femoral head.At present,there is a lack of research on the correlation between gluteus medius status and non-traumatic femoral head necrosis. OBJECTIVE:To investigate the relationship between the gluteus medius width ratio and the medial space ratio of the hip joint and the progression of non-traumatic femoral head necrosis,and to explore the effect of gluteus medius atrophy on the surface and necrotic zone stress of the femoral head necrosis through finite element analysis. METHODS:Retrospective analysis of unilateral non-traumatic femoral head necrosis patients admitted to Third Affiliated Hospital of Guangzhou University of Chinese Medicine was performed.All patients were followed up for an average of more than 2 years.They were divided into a collapsed group and a non-collapsed group based on whether there was collapse of the femoral head during the follow-up.Medial space ratio,gluteus medius width ratio,Sharp angle,gluteus medius length ratio,and gluteus medius activation angle were measured and calculated.The differences in these indicators were compared between the two groups.At the first visit and follow-up at 3,6,12,and 24 months,the medial space ratio and gluteus medius width ratio were measured and calculated to explore the changes of these two indicators in the course of non-traumatic femoral head necrosis.In addition,using three-dimensional finite element analysis,a Japanese Investigation Committee classification C1 type femoral head necrosis model was constructed based on CT data.At the same time,based on MRI data,a model of the gluteus medius muscle was constructed and divided into a gluteus medius muscle atrophy group(gluteus medius width ratio:74%-76%)and a gluteus medius muscle normal group(gluteus medius width ratio:94%-96%).Each group constructed 10 models,with 6 degrees of freedom of the distal femur constrained to zero.600 N pressures were applied along the Z-axis to the upper surface of the sacrum.The stress distribution,maximum stress values on the surface and necrotic area of the femoral head,and the maximum displacement of the necrotic area were compared between two groups of models. RESULTS AND CONCLUSION:(1)A total of 153 patients(67 males and 86 females)with 153 hips were included in this study.(2)At the 24-hour follow-up,the medial space ratio of the collapsed group was significantly higher than that of the non-collapsed group(P<0.05).The gluteus medius width ratio of the collapsed group was significantly lower than that of the non-collapsed group(P<0.05).There was no statistically significant difference in Sharp angle,gluteus medius activation angle,and gluteus medius length ratio between the two groups(P>0.05).(3)Since the follow-up time exceeded 3 months,the gluteus medius width ratio of the collapsed group was lower than that of the non-collapsed group(P<0.05).Since the follow-up time exceeded 12 months,the medial space ratio of the collapsed group was higher than that of the non-collapsed group(P<0.05).(4)Pearson correlation analysis showed a significant positive correlation between follow-up time and medial space ratio in the collapsed group(P<0.05),and a significant negative correlation between follow-up time and gluteus medius width ratio(P<0.05).The regression coefficient of gluteus medius width ratio was larger than that of medial space ratio.(5)The group with middle gluteal muscle atrophy showed significant stress concentration on the surface of the femoral head,and the stress zone was significantly located on the outside.The maximum stress on the surface of the femoral head in the group with middle gluteal muscle atrophy was significantly greater than that in the group with normal middle gluteal muscle(P<0.05).There was significant stress concentration in the necrotic area of the middle gluteal muscle atrophy group,and the maximum stress was located at the edge of the necrotic area.The maximum stress and maximum displacement in the necrotic area of the middle gluteal muscle atrophy group were significantly greater than those of the normal group(P<0.05).(6)It is indicated that gluteus medius width ratio is an effective indicator for evaluating changes in gluteal muscle atrophy.In the progression of non-traumatic femoral head necrosis,atrophy of the gluteus medius muscle first occurs,followed by widening of the medial hip joint space.The mechanical mechanism may be that the atrophy of the gluteus medius muscle affects the stability of the hip joint,leading to external displacement of the femoral head,and increasing stress and displacement on the surface and necrotic area of the femoral head.

To summarize the clinical experience of Professor LIU Jinmin in treatment for epilepsy. It is believed that main pathogenesis of epilepsy is yangming failure to close and vital activity loss control， so a therapeutic approach focused on restoring the closure of yangming and regaining vital activity was proposed for the treatment of epilepsy. For excess syndrome， the treatment focuses on draining excess and descending qi， promoting purgation and restoring spirit. When yangming dryness-heat predominates， the approach involves unblock the bowels and regulating the spirit， descending qi and reducing fire， with modified Chengqi Decoction （承气汤） as prescription； when yangming phlegm-fire predominates， the treatment focuses on clearing heat and resolving phlegm， calming mind and suppressing fright， with modified Qingxin Wendan Decoction （清心温胆汤） as prescription； when yangming blood stasis predominates， the approach involves breaking up blood stasis and promoting purgation， eliminating stasis and awakening the mind， with Taoren Chengqi Decoction （桃核承气汤） as prescription. For deficiency syndrome， the treatment emphasizes tonifying deficiency and raising qi， strengthening the stomach and nourishing the spirit. When center qi deficiency and sinking of clear qi of the nutrients from food， the approach involves replenishing and uplifting qi while nourishing vital activity， with modified Liujunzi Decoction （六君子汤） as prescription； when yin deficiency and fluid consumption， the treatment focuses on nourishing stomach and tonifying yin， promoting fluid production and calming the spirit， with modified Maimendong Decoction （麦门冬汤） combined with Yiwei Decoction （益胃汤） as prescriptions. In clinical situations of deficiency-excess complex， it is essential to distinguish the primary condition from the secondary， applying both supplementing and draining methods flexibly to achieve optimal treatment.
