In this study, fluvoxamine maleate sustained-release pellet system tablets were prepared and were used to evaluate their release behaviors in vitro. Fluvoxamine maleate pellets were prepared using centrifugal-spherization method and coated by fluidized bed as bottom-spray. The multi-unit sustained-release pellets and appropriate excipients for prescription volumes were mixed uniformly and then compressed to tablets. Screening and determining the optimal formulation of drug loaded pellets through L8 (2⁴) Taguchi experiment. Using Minitab software to design a DOE experiment with 2⁴ partial factors, including material temperature, fan speed, atomization pressure, and spray rate to optimize the bottom spray coating process. Taking monostearate glycerol ester with a particle size of 24-40 mesh as the main diluent for tableting to relieve the delamination phenomenon between pellets and excipients during tablet pressing and reduce mechanical damage to the coating film. By examining the powder fluidity indexes such as angle of repose, bulk density, tapped density, and Hausner ratio of mixed particles, it was found that the flowability and compressibility are good and suitable for direct compression. Evaluate the basic properties of the sustained-release tablets, investigate the in vitro release behavior and study the release mechanism. The results of in vitro release test showed that the self-made sustained-release tablets could disintegrate into independent pellet units in phosphate buffer at pH 6.8 and release slowly within 24 h, which conformed to the first-order drug release model. The fluvoxamine maleate sustained-release pellet system tablets meet the requirements of preparation design and has a great commercial prospect.

Objective To investigate the clinical efficacy of Lianhua Qingyou Decoction combined with acupuncture in the treatment of Helicobacter pylori(Hp)-infected chronic atrophic gastritis(CAG),and to observe the effect on gastrointestinal function.Methods Ninety-eight patients with Hp-infected CAG of heat stagnation in the liver and stomach type were randomly divided into a study group and a control group,with 49 patients in each group.The control group was treated with standard anti-Hp quadruple therapy,and the study group was treated with Lianhua Qingyou Decoction combined with acupuncture on the basis of treatment for the control group.The treatment course for the two groups covered 12 weeks.Before and after the treatment,the two groups were observed in the scores of pathohistological changes in the gastric mucosal atrophy,intestinal epithelial hyperplasia,inflammatory response,activity and Hp infection,gastrointestinal function indicators of serum gastrin,motilin,vasoactive intestinal peptide(VIP),and somatostatin,and the levels of pepsinogens of PGⅠand PGⅡ.After treatment,the clinical efficacy and Hp negative-conversion rate in the two groups were compared.Results(1)After 12 weeks of treatment,the total effective rate in the study group was 95.92%(47/49)and that in the control group was 73.47%(36/49),and the intergroup comparison(by chi-square test)showed that the therapeutic efficacy of the study group was significantly superior to that of the control group(P＜0.01).(2)After treatment,the scores of pathohistological changes in the gastric mucosal atrophy,intestinal epithelial hyperplasia,inflammatory response,activity and Hp infection in the two groups were decreased compared with those before treatment(P＜0.05),and the decrease in the study group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the serum levels of gastrointestinal function indicators of gastrin,motilin and somatostatin in the two groups were all higher than those before treatment(P＜0.05),and the serum VIP level was lower than that before treatment(P＜0.05).The increase in the serum gastrin,motilin and somatostatin levels and the decrease in the serum VIP level of the study group were significantly superior to those of the control group(P＜0.01).(4)After treatment,the serum pepsinogen levels of PGⅠ and PGⅡ in the two groups were higher than those before treatment(P＜0.05),and the increase in the study group was significantly superior to that in the control group(P＜0.01).(5)The Hp negative-conversion rate of the study group was 95.92%(47/49),which was significantly higher than that of the control group(79.59%,39/49)and the difference was statistically significant(χ2 = 6.078,P = 0.014).Conclusion For the treatment of patients with Hp-infected CAG of heat stagnation in the liver and stomach type,Lianhua Qingyou Decoction combined with acupuncture can effectively enhance the clinical efficacy and Hp negative-conversion rate,improve the pathohistological scores and gastrointestinal function,and regulate the serum PGⅠand PGⅡlevels.

Objective To explore the prognostic factor and its predictive value of patients with Wilson disease-related acute-on-chronic liver failure(WD-ACLF).Methods The clinical data of 70 patients diagnosed as WD-ACLF admitted to the Department of Encephalopathy of the First Affiliated Hospital of Anhui University of Chinese Medicine from January 1,2017 to January 1,2022 were retrospectively collected.According to the 12-week prognosis,patients were divided into survival group(n=36)and death group(n=34).The data of the two groups were analyzed by univariate and multivariate logistic analysis to screen the prognostic risk factors and evaluate their predictive value.The model coefficient is omnibus tested,and the model-fitting degree is evaluated by the Hosmer-Lemeshow test.ROC curve was used to analyze the prognostic value for WD-ACLF between the new model and chronic liver failure-sequential organ failure assessment(CLIF-SOFA)score,model for end-stage liver disease(MELD)score and Child-Turcotte-Pugh(CTP)score.Results A total of 70 WD-ACLF patients were enrolled in present study,including 36 cases in survival group[22 males and 14 females with median age of 30.0(17.3,40.0)]and 34 cases in death group[25 males and 9 females with median age of 34.0(28.8,41.0)].Univariate analysis showed that the course of disease,prothrombin time(PT),activated partial thromboplastin time(APTT)were shorter in survival group than that in death group,the white blood cells(WBC),international normalized ratio(INR),aspartate transaminase(AST),total bilirubin(TBIL),blood urea nitrogen(BUN),creatinine(Cre)and ceruloplasmin(CER)levels and the proportion of infection,ascites,and upper gastrointestinal bleeding were lower in survival group than those in death group,however,the proportion of infection,ascites and upper digestive bleeding in the survival group were lower than those in the death group.Meanwhile,the red blood cells(RBC),hemoglobin(Hb),Na+ and total cholesterol(TC)level in the survival group were higher than those in the death group(P<0.05 or P<0.01).The results of multivariate logistic regression analysis showed that disease course(OR=1.176,95%CI 1.043-1.325),INR(OR=7.635,95%CI 1.767-32.980),TBIL(OR=1.012,95%CI 1.003-1.021),and upper gastrointestinal bleeding(OR=11.654,95%CI 1.029-131.980)were independent risk factors affecting the prognosis of WD-ACLF(P<0.05).Based on the results of logistic regression analysis,a joint model for predicting the prognosis of WD-ACLF was established.The AUC of the model for evaluating the prognosis of WD-ACLF was 0.941,which was greater than the CLIF-SOFA score(AUC=0.802),MELD score(AUC=0.897),and CTP score(AUC=0.722).Conclusions The course of disease,TBIL,INR,and upper gastrointestinal bleeding are risk factors that affect the prognosis of WD-ACLF.The prognosis model established based on this can more accurately predict the prognosis of WD-ACLF patients,and its predictive value is superior to CLIF-SOFA score,MELD score,and CTP score.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.
