LV Shao-guang believes that the essence and core of Chinese traditional medicine is a kind of treatment based on syndrome differentiation.The theory of treatment based on syndrome differentiation is the general and fundamental principle of Chinese tradition medicine diagnosis and treatment.The thoughts of syndrome differentiation are:the four diagnostic methods are ways and the eight principal syndromes are outlines.The treatment methods are:the integration of disease differentiation and symptom differentiation,study and analysis of Chinese traditional medicine agents illustrate the material basis of such agents,the pharmacodynamics of Chinese traditional medicine agents are explained in a scientific theoretic ways and the curative effect of Chinese traditional medicine agents are further enhanced.The thoughts and methods of treatment based on syndrome differentiation are enriched with the help of clinical lab test.The clinical physical examinations and chemical tests are the general principle of disease diagnosis and effect judgment.

Eight cases of hypothyroid myopthy admitted in Zhanshan Hospital Xiamen University from 1995 to 2011 were retrospectivrely analyzed.The main clinical features were proximal muscle weakness,susceptibility to fatigue,and elevation of muscle enzymes.Electromyography revealed no specific findings.All patients obtained clinical recovery after thyoid hormone replacement.Hypothyroid myopathy should be considered in cases of muscle weakness and elevation of muscle enzymes.

Objective To investigate expression level of endoplasmic reticulum stressmarker GRP78 in the testicular tissue in rats with different phases of morphine-dependence. To explore the role of ERS in morphine-de-pendence. Methods SD rats were divided into 6 groups: morphine (mor) -withdrawal group, mor-extinct group, mor-kindling group and their control groups, normal saline (NS)-withdrawal group, NS-extinct group, NS-kindling group. The experimental rats were injected with morphine subcutaneously on increasing dosage to establish the con-ditioned place preference (CPP) model. The rats in control groups were injected NS. Then the rats were suffered from withdrawal for 48 h, extinction and kindling by morphine, separately. The GRP78 expression level in testicular tissues of rats in the time point mentioned above were measured using Western Blot. Results The time of rats in the paired-box was (528.0 ± 81.0) s, which was significantly higher than that in the NS control group (P<0.001). It was (396.8 ± 116.9) s after extinctive phase, which was significantly higher than that the withdrawal phase of rats (P < 0.001). Also it was (396.8 ± 116.9) s after kindling with morphine which was significantly higher than that the extinctive phase of rats (P < 0.001). These changes of the time indicated that the animal models of extinction and kindling were established in the study. The GRP78 levels were down-regulated in 48 h after withdrawal (P <0.05), and increased a bit afterextinctive phase, but up-regulated highly after kindling with morphine (P < 0.01). Conclusion ERS may be related in the morphine dependence and it might play an important role of testicular dys-function in male drugabuser.

Objective To evaluate the effect and safety of intravenous (IV) thrombolysis, intra-arterial (IA) thrombolysis and mechanical adjuvant intra- arterial thrombolysis (IA + MA) in treating cardiogenic cerebral embolism. Methods A total of 66 patients with cardiogenic cerebral embolism were randomly divided into IV group (n = 25), IA group (n = 18), IA + MA group (n = 23). The artery recanalization rate, NIHSS score, GCS score, BI excellent rate, symptomatic intracranial hemorrhage rate and mortality after different thrombolytic therapies were determined. The results were compared between each other among the three groups. Results In all three groups both the post-treatment NIHSS score and GCS score were significantly improved when compared with pre-treatment ones (P < 0.05). In IA + MA group the artery recanalization rate was 78.3%(18/23) and the BI excellent rate was 40%(10/25), which were significantly higher than those in IV group (P < 0.05). The symptomatic intracranial hemorrhage rate in IA group was 5.6%(1/18), which was strikingly lower than that in IV group (32%, 8/25). Analysis of the causes showed that the artery recanalization rate in patients with valvular heart disease or cardiac myxoma was rather lower, but the intracranial hemorrhage rate and mortality in these patients were much higher. Conclusion Thrombolytic therapy can improve neurological deficit in cardiogenic cerebral embolism, and the therapeutic effect of mechanical adjuvant intra- arterial thrombolysis is definitely better.

BACKGROUND:Tranexamic acid is a synthetic anti-fibrinolytic drug, and can effectively control blood loss after total knee arthroplasty through vein. OBJECTIVE:To evaluate the effectiveness and safety of tranexamic acid in reducing blood loss after primary unilateral total knee arthroplasty. METHODS:From 2014 to 2015, 100 patients from the Department of Lower Limb, Sichuan Orthopaedic Hospital underwent primary unilateral total knee arthroplasty, and randomly divided into test group which used tranexamic acid and control group which used tranexamic acid, with 50 cases in each group. 1 g tranexamic acid was infused into the vein at 10 minutes before total knee arthroplasty in the test group, but tranexamic acid was not given in the control group. RESULTS AND CONCLUSION:The amount of total blood loss, postoperative wound drainage in 24 hours, and the amount of blood transfusion were significantly less in the test group than in the control group (P < 0.05). No significant differences in intraoperative blood loss and the number of patients receiving blood transfusion were found between the test and control groups. No significant difference in preoperative hemoglobin levels was detected before surgery, but hemoglobin levels were decreased after surgery between the two groups. Postoperative hemoglobin levels were apparently higher in the test group than in the control group after surgery. At 24 hours after surgery, no significant difference in coagulation was detectable between the two groups. At 6 days, double lower limb vein color Doppler ultrasound examination did not reveal deep vein thrombosis in both groups. These findings verify that treatment with tranexamic acid in the vein before primary unilateral total knee arthroplasty can evidently diminish the amount of perioperative blood loss and blood transfusion, reduce the risk and cost of blood transfusion, which is good for rehabilitation and does not increase the risk of deep vein thrombosis.

Objective To compare the effects of peripatellar peripheral nerve partially and totally depolarized in total knee arthroplasty (TKA). Methods 66 TKA patients were divided into partially depolarized group (A, 42 knees) and totally depolarized group (B, 38 knees). The scores of knee-joint, Feller and Visual Analogue Scale were recorded. Results There was no significant difference in all the scores between 2 groups before operation (P>0.05). All the scores improved after operation (P<0.05), however, there was still no significant difference between 2 groups (P>0.05). Conclusion Patellar peripheral nerve partially depolarization technique can reduce postoperative knee pain, which has the same effect with totally depolarization.

Objective:To explore the effect of self-made Yiqi Yangyin Decoction on immune function, serum tumor markers and toxic and side effects of chemotherapy in patients with advanced gastric cancer chemotherapy.Methods:A total of 88 patients with advanced gastric cancer who met the inclusion criteria in the hospital between December 2018 and December 2020 were divided into two groups according to the random number table method, with 44 in each group. The control group was treated with chemotherapy, and the observation group was given self-made Yiqi Yangyin Decoction on the basis of the control group. The two groups were treated for 4 consecutive cycles with 3 weeks as 1 cycle. The Traditional Chinese Medicine (TCM) symptoms were scored before and after treatment, and the levels of IgG, IgA and IgM were detected by immunoturbidimetry. The levels of carcinoembryonic antigen (CEA) and cancer antigen 125 (CA125) were detected by ELISA. The gastrointestinal reactions, thrombocytopenia, anemia, leukopenia and neurotoxicity were recorded and evaluated during treatment, and the clinical efficacy was assessed.Results:The total effective rate was 81.8% (36/44) in observation group and 61.4% (27/44) in control group (χ 2=4.53, P<0.05). After treatment, the scores of stomachache and gastric distension, poor appetite, shortness of breath, and drooping spirit in observation group were significantly lower than those in the control group ( t=17.28, 11.91, 5.02, 5.65, all Ps<0.001) while the levels of serum IgG [(9.39±0.46)g/L vs. (8.54±0.23) g/L, t=10.96], IgA [(1.35±0.42) g/L vs. (1.07±0.15) g/L, t=6.90] and IgM [(0.92±0.09) g/L vs. (0.78±0.10) g/L, t=4.17] were significantly higher than those in the control group ( P<0.01). The levels of serum CEA [(9.07±1.01) μg/L vs. (14.89±2.13) μg/L, t=16.38] and CA125 [(24.87± 4.68) kU/L vs. (30.75±5.33) kU/L, t=5.50] were significantly lower than those in the control group ( P<0.01). During treatment, the toxic and side effects of gastrointestinal reactions, thrombocytopenia, anemia, leukopenia and neurotoxicity were significantly lower in the observation group than those in the control group ( Z=18.52, 2.54, 3.12, 3.84, 2.34, P<0.05). Conclusion:Self-made Yiqi Yangyin Decoction can improve the TCM symptoms, enhance the immunity, reduce the levels of serum tumor markers, and relieve the toxic and side effects of chemotherapy of patients undergoing chemotherapy for advanced gastric cancer.

To screen the pathogenic mutation location in a genetic family with the neurofibromatosis (NF1) by the next generation sequencing and analyze the clinical phenotype,Illumina Miseq sequencing was applied to capture and analyze the target regions of NF1 family's probands,and furtherly find out the suspicious mutations,as well as to verify the family members by Sanger sequencing.Two rare variants were identified in proband,including the heterozygous missense mutation c.C3649T (p.P1217S) in KIF1B gene and the missense mutation c.T6311C (p.L2104P) on exon 41 of NF1 gene (NM_000267.3).The amino acid at position 2104 was found to be changed from leucine to proline in NF1.The protein prediction SIFT and Polyphen-2 values were 0,0.997,which predicted a conformational change in the encoded protein and eventually affected its function.The mutation c.T6311C in NF1 gene was detected in all patients in this family,which showed genetic co-segregation.The clinical phenotype was neurofibroma in the spinal canal.There were no café au lait spots,iris Lisch nodules,scoliosis,tinnitus,heating loss,or elevated intracranial pressure.The missense mutation c.T6311C (p.L2104P) in NF1 gene might be the genetic cause of this hereditary disease of neurofibromatosis.

ObjectiveThis study is aimed to investigate the association of human leukocyte antigen (HLA)-DRB1 with rheumatoid arthritis (RA) in Chinese Han population.MethodsA total of 281 Chinese Han patients with RA and 202 healthy controls were recruited.DNA was extracted from PBMC and HLA typing was performed by sequence based typing and PCR-Sequence Specific Primer.The frequency of HLADRB1 was compared between patients and controls using x2 test with continuity correction.ResultsThe susceptible HLA-DRB1 alleles were * 0101,* 0102,*0404,* 0405,and * 0410 which belonged to QRRAA.DRRAA and DERAA were protective alleles.At genotypic level,The association of S3P and S3D was detected.However,the protective effect of S3D was shown to be in a recessive mode.ConclusionOur results have shown that there are racial differences in RA susceptibility between Chinese Han population and Caucasians.
