Houpo Sanwutang， included in the Catalogue of Ancient Classical Prescriptions （Second Batch）， was first recorded in the Synopsis of Golden Chamber written by ZHANG Zhongjing from the Eastern Han dynasty and was modified by successive generations of medical experts. A total of 37 pieces of effective data involving 37 ancient Chinese medical books were retrieved from different databases. Through literature mining， statistical analysis， and data processing， combined with modern articles， this study employed bibliometrics to investigate the historical origin， composition， decoction methods， clinical application， and other key information. The results showed that the medicinal origin of Houpo Sanwutang was clearly documented in classic books. Based on the conversion of the measurements from the Han Dynasty， it is recommended that 110.4 g Magnolia Officinalis Cortex， 55.2 g Rhei Radix et Rhizoma， and 72 g Aurantii Fructus Immaturus should be taken. Magnolia Officinalis Cortex and Aurantii Fructus Immaturus should be decocted with 2 400 mL water first， and 1 000 mL should be taken from the decocted liquid. Following this， Rhei Radix et Rhizoma should be added for further decoction， and then 600 mL should be taken from the decocted liquid. A single dose of administration is 200 mL， and the medication can be stopped when patients restore smooth bowel movement. Houpo Sanwutang has the effect of moving Qi， relieving stuffiness and fullness， removing food stagnation， and regulating bowels. It can be used in treating abdominal distending pain， guarding， constipation， and other diseases with the pathogenesis of stagnated heat and stagnated Qi in the stomach. The above results provide reference for the future development and research of Houpo Sanwutang.

Objective To investigate the clinical characteristics,treatment methods,and prognosis of a-cute leukemia patients with extramedullary infiltration.Methods The clinical characteristics and treatment methods of 47 acute leukemia patients with extramedullary infiltration admitted to the Affiliated Hospital of Guizhou Medical University from April 2014 to April 2023 were retrospectively analyzed.Subgroup analysis was performed according to whether there was extramedullary infiltration before transplantation,and whether there was isolated extramedullary recurrence after transplantation.Based on this analysis,the patients were di-vided into the pre-transplantation radiotherapy group and pre-transplantation non-radiotherapy group,the post-transplantation radiotherapy group and post-transplantation non-radiotherapy group.According to the treatment methods of central nervous system leukemia(CNSL),the patients were divided into the intrathecal injection group(n=12)and combination of intrathecal injection and radiotherapy group(n=13).The local remission situation,survival duration,and toxic and side effects of radiotherapy and chemotherapy were com-pared.Results For acute leukemia patients with extramedullary infiltration,the overall survival time(OS)in the radiotherapy group was better than that in the non-radiotherapy group(median OS:706 d vs.151 d,P=0.015).Subgroup analysis showed that the OS of the pre-transplantation radiotherapy group was better than that of the pre-transplantation non-radiotherapy group(median OS:592 d vs.386 d,P=0.035).For CNSL,the combination of intrathecal injection and radiotherapy group had a better OS than the intrathecal injection group(median OS:547 d vs.388 d,P=0.045).The event-free survival time(EFS)of the radiotherapy group was better than that of the non-radiotherapy group(median EFS:175 d vs.50 d,P=0.005).The COX pro-portional-hazards model showed that treatment with or without radiotherapy had a significant impact on the OS of acute leukemia patients with extramedullary infiltration.The risk of death in the pre-transplantation non-radiotherapy group was 2.231 times higher than that in the pre-transplantation radiotherapy group(HR=3.231,95％CI:1.021-10.227,P=0.046).Compared with the non-radiotherapy group,the radiother-apy group had a higher local remission and a lower risk of haematological toxicity,infection,and haemorrhage.Conclusion Radiotherapy can rapidly alleviate the local symptoms of acute leukemia complicated with extr-amedullary infiltration,prolong the survival time of these patients,and reduce the risk of hematologic toxicity,infection,and haemorrhage.

Objective To investigate the influence of peripheral blood neutrophil-to-lymphocyte ratio (NLR),monocyte-to-lymphocyte ratio (MLR) and platelet-to-lymphocyte ratio (PLR) on the prognosis in the patients with multiple myeloma (MM).Methods A total of 159 newly diagnosed MM admitted and treated in the Affiliated Hospital of Guizhou Medical University from January 2019 to May 2023 were selected as the study subjects.The general clinical data,blood biochemical and marrow routine detection results before the in-itial treatment were collected.NLR,MLR and PLR were calculated.The univariate and multivariate Cox-re-gression model was adopted to analyze the influencing factors.The receiver operating characteristic (ROC) curve was used to analyze the predictive value.The Kaplan-Meier survival curve and Log-Rank test were used to conduct the survival analysis.Results The ROC curve showed that the critical values of NLR,MLR and PLR were 2.682,0.317 and 147.786 respectively.The patients were divided into the high/low NLR groups (n=61,n=98),high/low MLR group (n=76,n=83) and high/low PLR groups (n=59,n=100).The pro-portions of blood calcium<2.5 mmol/L and creatinine<177 μmmol/L in the low NLR group in the low NLR group were higher compared with the high NLR group (P<0.05);the blood calcium,creatinine and DS stage had statistical differences between the low MLR group and high MLR group (P<0.05);blood calcium had statistical difference between the low PLR group and high PLR group (P<0.05).After 3 treatment courses,the complete remission rate in the high NLR group,high MLR group and high PLR group was significantly lower than that in the corresponding low group (P<0.05).The multivariate Cox-regression analysis results showed that hemoglobin<100 g/L and high PLR were the independent risk factors affecting the progress free survival (PFS) stage in the patients with MM (P<0.05).The age>60 years old was the independent risk factors affecting the overall survival (OS) in the patients with MM (P<0.05).Conclusion NLR,MLR and PLR could serve as the assisted tool to evaluate the prognosis in the patients with MM.

Objective:To screen mutations of the adenosine triphosphate(ATP)-binding cassette transporter A3(ABCA3)gene in elderly Chinese individuals with lung interstitial diseases(ILDs)and to analyze the clinical characteristics of ILDs in elderly patients.Methods:A prospective study, After further image analysis of patients diagnosed with interstitial lung diseases between September 2015 and December 2018 at the Department of Respiratory and Critical Care Medicine, the Second Xiangya Hospital of Central South University, 103 patients were willing to provide peripheral blood samples and signed informed consent.DNA samples were extracted and whole exome sequencing was performed to screen ABCA3 gene mutations.Clinical data of patients were summarized and analyzed.Results:Seven rare variants of the ABCA3 gene were identified in 6 patients, with a mean age of 67 years(69-73 years)and an equal sex distribution, and 33.3%(2/6)were smokers.The most notable presentation was diffuse lung lesions.Patients' final diagnoses included idiopathic pulmonary fibrosis(IPF, 3/6), nonspecific interstitial pneumonia(NSIP, 1/6), and IgG4-related lung disease(2/6). Meanwhile, compound heterozygous mutations of the ABCA3 gene responsible for IPF were identified in patient No.39, including p. Asp1465Asn, p.Leu3Vval and p. Val93Ile3, a new finding in patients with ILDs.Conclusions:ABCA3 mutation-related lung interstitial diseases exhibit variable characteristics, with differences in the age of onset, clinical manifestations, imaging features and prognosis between patients.ABCA3 mutations responsible for early-onset ILDs are mostly homozygous or compound heterozygous and usually highly pathogenic nonsense mutations.In contrast, ABCA3 mutations identified in elderly patients with ILDs are often missense mutations, a possible explanation for the variability of ILDs in the elderly.Since patients with ILDs caused by ABCA3 variants respond poorly to currently available treatment options, early genetic diagnosis may benefit patients by enhancing disease awareness.

Objective:By analyzing factors associated with lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years old, a nomogram model for lower urinary tract symptoms was constructed to assist the clinical development of targeted interventions to reduce the incidence of lower urinary tract symptoms in this population.Methods:In the cross-sectional study, 798 middle-aged and elderly women aged 55-65 years receiving physical examination in the Health Management Center of Third Xiangya Hospital from November 2013 to December 2020 were selected as research participants.Univariate regression analysis was used to compare differences in the basic data related to lower urinary tract symptoms in the population.Multivariate Logistic regression analysis was used to identify related influencing factors, and a nomogram model for lower urinary tract symptoms in the population was established.Results:Among 798 middle-aged and elderly women surveyed, the prevalence of lower urinary tract symptoms was 81.08 %(647 cases), and the rate of urinary tract infections was 21.48 %(139 cases). Variables with statistical significance in univariate regression analysis were included in multivariate Logistic regression analysis.The results showed that body mass index, vaginal delivery, strength of pelvic floor type Ⅱ fiber muscle, pelvic and abdominal coordination and mental health were independent influencing factors for lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years( OR=1.099, 2.681, 0.895, 0.658, 1.057, P=0.010, 0.030, 0.040, 0.010, 0.038). The monogram model based on the five risk prediction indexes produced a consistency index(C-index)of 0.651 and a diagnostic sensitivity and specificity of 66.9% and 58.9%, respectively.The correction curve showed that the predicted results of the model were essentially the same as the actual probability of condition. Conclusions:In this study, the independent influencing factors for lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years were screened by univariate regression and multivariate Logistic regression analysis and a nomogram model for risk prediction of the population was constructed, was proved to have a good ability for accurately and effectively predicting the risk of lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years, and will assist clinicians to screen for high-risk patients, formulate targeted interventions, and reduce the incidence of lower urinary tract symptoms in middle-aged and elderly women aged 55-65 years.

Objective To evaluate the effect of dexmedimidine on intestinal injury in rats with endotoxemia.Methods Twenty-four healthy adult male Sprague-Dawley rats,aged 2-3 months,weighing 200-250 g,were divided into 4 groups (n =6 each) using a random number table method:control group (group C),endotoxemia group (group E),dexmedimidine group (group D) and dexmedimidine plus α7 subunit-containing nicotinic acetylcholine receptor antagonist group (D +α-BGT group).The endotoxemia model was established by injecting lipopolysaccharide (LPS) 10 mg/kg via the femoral vein.Dexmedetomidine 40 μg/kg was injected and 15 min later LPS was intravenously injected in group D.Dexmedetomidine 40 μg/kg was intraperitoneally injected after intraperitoneal injection of α-bungarotoxin 1 μg/kg,and 15 min later LPS was intravenously injected in group D+o-BGT.Blood samples were collected from the abdominal aorta at 6 h after LPS injection for determination of the plasma interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) concentrations (by enzyme-linked immunosorbent assay).Rats were sacrificed after blood sampling,and intestinal tissues were obtained for examination of the pathological changes and for determination of the myeloperoxidase (MPO) activity (by chemical colorimetry) and expression of NF-κB p65 in nucleoprotein (by Western blot).Results Compared with group C,the plasma IL-6 and TNF-o concentrations and MPO activity in intestinal tissues were significantly increased,and the expression of NF-κB p65 in nucleoprotein was up-regulated in the other 3 groups (P＜0.05).Compared with group E,the plasma IL-6 and TNF-α concentrations and MPO activity in intestinal tissues were significantly decreased,the expression of NF-κB p65 in nucleoprotein was down-regulated (p＜0.05),and the pathological changes of intestinal tissues were significantly attenuated in group D.Compared with group D,the plasma IL-6 and TNF-α concentrations and MPO activity in intestinal tissues were significantly increased,the expression of NF-κB p65 in nucleoprotein was up-regulated (P＜0.05),and the pathological changes of intestinal tissues were accentuated in group D+α-BGT.Conclusion Dexmedetomidine can reduce the intestinal injury in rats with endotoxemia,and the mechanism may be related to activating cholinergic anti-inflammatory pathway and further inhibiting inflammatory responses.

Calcific uremic arteriopathy (CUA), termed calciphylaxis, is a rare but highly fatal clinical syndrome. There is no clearly laboratory diagnostic criteria for CUA. The medium and small arterial calcification and microthrombosis discovered by skin biopsy, radiologic imaging，bone scan and the evidence of activation of the bone morphogenetic protein signal (BMPs) transduction pathway are useful for early diagnosis of this disease. The common therapies (including intravenous sodium thiosulfate (STS) and bisphosphonates, hyperbaric oxygen therapy and other symptomatic supports) are used for the management of wounds, pain, nutrition, dialysis and so on. Controlling the chronic kidney disease-mineral and bone disorder (CKD-MBD) and some complications of dialysis and drugs (such as warfarin, active vitamin D) can prevent CUA. However, CUA patients still have poor prognosis and high mortality. Since some patients progress rapidly, it is of great importance to make early diagnosis and provide effective treatments with multidisciplinary management.

Objective:To observe the clinical characteristics with different peritoneal transport type in patients with continuous ambulatory peritoneal dialysis (CAPD),and to investigate the factors associated with peritoneal transport function.Methods:The clinical data of 158 CAPD patients were analyzed retrospectively.According to peritoneal equilibration test,a method for evaluation of the peritoneal transport function,the patients were divided into 2 groups:a high average and high peritoneal transport group (Group A,n=84) and a low average and low peritoneal transport group (Group B,n=74).T-he demographics,clinical biochemical indexes and the incidence of cardiovascular complications were compared between the 2 groups.Logistic regression analysis was used to find the factors relevant to peritoneal transport function.Results:The level of serum albumin (ALB) in the Group B was significantly higher than that in the Group A (P＜0.05).The 4 h dialysate/plasma creatinine (D/Pcr),high-sensitivity C-reactive protein (hs-CRP),body mass index (BMI),and the rates of cardiovascular complications in the Group A were significantly higher than those in the Group B (P＜0.05).Correlation analysis showed that the D/Pcr was positively correlated with the BMI,serum hs-CRP and cardiovascular complications (r=0.179,0.373 and 0.426,respectively,P＜0.05),while it was negatively correlated with ALB (r=-0.393,P＜0.01).Logistic regression analysis showed that the high BMI (OR=1.178,P＜0.05),cardiovascular complications (OR=5.035,P＜0.01),and the low serum ALB (OR=0.852,P＜0.01)were the risk factors for high peritoneal transport.Conclusion:The serum ALB level,BMI and the cardiovascular complications are associated with high peritoneal transport,which are useful markers for predicting the peritoneal transport function before peritoneal dialysis.

OBJECTIVE: To investigate the associations between chronic kidney disease (CKD) and body mass index (BMI), waist circumference(WC), waist-to-height ratio (WheiR) in Chinese adults.
 METHODS: A total of 26 655 participants, who voluntarily attended annual health examination at the Health Management Center in the Third Xiangya Hospital of Central South University from June 2013 to February 2014, were enrolled for this study. Logistic regression and receiver operating characteristic (ROC) curve analysis were performed.
 RESULTS: The prevalence rate of CKD was 9.6% and 3.1% in male and female subjects, respectively. Multivariate logistic regression analysis showed that BMI, WC and WheiR were independent risk factors for CKD in diabetic male and hypertensive male subjects (P<0.01). However, no association between these obesity indices and CKD was found in women after multivariate adjustment. In diabetic male subjects, when BMI≥28.7 kg/m(2), WC=90.7 cm and WheiR=0.56, the sensitivity and specificity prediction for CKD was 24.8%, 58.5%, 45.5% and 83.3%, 54.4%, 69.6%, respectively. In hypertensive male subjects, when the optimum cut-off points for BMI, WC and WheiR were ≥
27.0 kg/m(2), 91.2 cm and 0.54, the sensibility prediction for CKD were 41.0%, 47.0% and 50.1%, respectively, while the specificity prediction were 68.0%, 63.0% and 61.4%, respectively. The area under the ROC curve of BMI, WC, WheiR for CKD prediction were 0.56, 0.57, 0.59 in diabetic male subjects and 0.54, 0.56, 0.57 in hypertensive male subjects, respectively.
 CONCLUSION BMI, WC and WheiR are associated with the increased risk for CKD in diabetic or hypertensive male subjects. However, the value for these obesity indices is limited in screening CKD.
