Objective: To evaluate the efficacy and safety of Jiawei Simiao powder (JWSMP) combined with celecoxib for the treatment of acute gouty arthritis by conducting a meta-analysis of randomized controlled trials (RCTs). Methods: The Chinese National Knowledge Infrastructure Databases, Chinese Scientific Journal Database, Wanfang, Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched from inception until December 2023. Continuous variables were analyzed using the mean difference (MD) for analysis, and dichotomous variables were used as risk ratios. Data with similar characteristics were pooled for meta-analysis, and heterogeneity was assessed using I2. The Cochrane Handbook was used to assess the risk of bias and quality. RevMan 5.3 software was used to perform the meta-analysis. Results: Thirteen RCTs involving 1007 patients were included in the study. The quality of the included studies was low (unclear randomization processes and insufficient blinding reporting). The group receiving JWSMP combined with celecoxib showed significantly lower levels of serum uric acid (SUA, MD = −66.32, 95% confidence interval (CI): −80.97 to −51.67, P < .001), erythrocyte sedimentation rate (ESR, MD = −6.05, 95% CI: −8.29 to −3.82, P < .001), C-reactive protein (CRP, MD = −7.39, 95% CI: −11.15, −3.63, P < .001), and joint pain score (VAS score, MD = −2.14, 95% CI: −2.4 to −1.88, P < .001) compared to celecoxib alone. Additionally, the JWSMP combined group had a higher total effective rate (risk ratio = 1.22, 95% CI: 1.14 to 1.29, P < .001) and fewer adverse compared to celecoxib alone. Conclusions JWSMP combined with celecoxib is more effective than celecoxib alone in improving the total efficacy rate, alleviating joint pain, and improving SUA, ESR, and CRP levels. JWSMP also reduced the occurrence of adverse events caused by celecoxib. However, the quality of the included studies was low, highlighting the need for further high-quality research with larger sample sizes and robust methodologies, such as double-blind randomization, to confirm these findings.

OBJECTIVE: To prepare customized porous silicone orbital implants using embedded 3D printing and assess the effect of surface modification on the properties of the implants. METHODS: The transparency, fluidity and rheological properties of the supporting media were tested to determine the optimal printing parameters of silicone. The morphological changes of silicone after modification were analyzed by scanning electron microscopy, and the hydrophilicity and hydrophobicity of silicone surface were evaluated by measuring the water contact angle. The compression modulus of porous silicone was measured using compression test. Porcine aortic endothelial cells (PAOECs) were co-cultured with porous silicone scaffolds for 1, 3 and 5 days to test the biocompatibility of silicone. The local inflammatory response to subcutaneous porous silicone implants was evaluated in rats. RESULTS: The optimal printing parameters of silicone orbital implants were determined as the following: supporting medium 4% (mass ratio), printing pressure 1.0 bar and printing speed 6 mm/s. Scanning electron microscopy showed that the silicone surface was successfully modified with polydopamine and collagen, which significantly improved hydrophilicity of the silicone surface (P < 0.05) without causing significant changes in the compression modulus (P > 0.05). The modified porous silicone scaffold had no obvious cytotoxicity and obviously promoted adhesion and proliferation of PAOECs (P < 0.05). In rats bearing the subcutaneous implants, no obvious inflammation was observed in the local tissue. CONCLUSION Poprous silicone orbital implants with uniform pores can be prepared using embedded 3D printing technology, and surface modification obviously improves hydrophilicity and biocompatibility of the silicone implants for potential clinical application.

OBJECTIVE: To evaluate the effects of the pestle needling therapy on the vibration perception threshold (VPT) and the quality of life (QOL) in the patients of high-risk diabetic foot. METHODS: A total of 132 patients of high risk diabetic foot were randomized into an observation group and a control group, 66 cases in each one. In the control group, the routine treatment and nursing for diabetes were applied. In the observation group, on the base of the treatment as the control group, the pestle needling therapy was used at , , , Zusanli (ST 36), Yongquan (KI 1), Sanyinjiao (SP 6) and Taixi (KI 3). The intervention with the pestle needling therapy was given once every day, consecutively for 4 weeks. The follow-up visit was conducted in 3 months and 6 months after the intervention. Vibration perception threshold (VPT) was observed before and after intervention in the two groups. Separately, before intervention, at the end of intervention, 3 months after intervention and 6 months after intervention, the type 2 diabetes mellitus quality life scale (DMQLS), the revised edition was adopted to compare the QOL between the two groups. The effects were evaluated in the two groups. RESULTS: After intervention, the VPT and QOL were all improved in the two groups (<0.01, <0.05). In the observation group, after intervention, VPT at the first toes and the dorsum of the feet was lower than the control group at the same time point (all <0.01). In the observation group, the total scores and the score of each dimension item in the DMQLS of the revised edition were all lower than the control group correspondently at the end of intervention, 3 months after intervention and 6 months after intervention (<0.01, <0.05). The repeated ANOVA results showed that the differences were significant in the total scores and the score of each dimension in the aspects of time, inter-group and interaction effect (<0.01, <0.05). The total scores and score of each dimension item in the DMQLS were lower than those the earlier time point (<0.01, <0.05). The total effective rate was 100.0% in the observation group, which was superior to 95.1% (59/62) in the control group (<0.05). CONCLUSION The pestle needling therapy reduces the foot VPT and improves the sensory nerve function of the foot and the QOL in the patients of high-risk diabetic foot.

Objective To investigate the correlation between BMI and insulin dose in diabetic patients after short-term continuous subcutaneous insulin infusion (CSII). Methods Three hundred patients with type 2 diabetes mellitus (T2DM) were enrolled and randomized into the normal weight (BMI < 23 kg/m2) group, overweight (BMI 23 ~ 25 kg/m2) group and obesity (BMI≥25 kg/m2) group. The metabolic and anthropometric parameters of each group were compared and the related factors which may influence insulin dose were analyzed. Results The insulin dose per weight in the overweight group or in the obesity groups was significantly lower than that in the normal weight group. Weight and BMI were negatively correlated with the insulin dose per weigh. Conclusions Differences of glycemia level , β-cell function and insulin resistance exist in Chinese type 2 diabetes patients with different BMI. The stratification of BMI should be considered before estimating the insulin dose by body weight in CSII therapy.

Objective To evaluate the effect of remifentanil preconditioning on hepatic ischemiarepeffusion (I/R) injury in rats with liver cirrhosis.Methods Healthy male Sprague-Dawley rats,weighing 160180 g,received 40％ tetrachloride carbon 3 ml/kg (in peanut oil) intragastrically twice a week for 8 weeks to induce liver cirrhosis.Thirty-five rats with liver cirrhosis were randomly divided into 5 groups (n =7 each) using a random number table:sham operation group (group S),group I/R,and preconditioning with different does of remifentanil groups (R1,R2 and R3 groups).Hepatic I/R injury was induced by clamping the branches of hepatic artery,portal vein and common bile duct in the left and median hepatic lobes for 30 min followed by 90 min reperfusion in anesthetized rats with liver cirrhosis.In R1,R2 and R3 groups,remifentanil was infused intravenously at 0.4,2.0 and 10.0 μg· kg-1· min-1 for 15 min,respectively,and the rats were exposed to ischemia for 30 min followed by 30 reperfusion starting from 10 min after infusion was stopped.At 90 min of reperfusion,blood samples were collected from the abdominal aorta for determination of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities.The rats were then sacrificed and livers were removed for determination of superoxide dismutase (SOD) activity,malondialdehyde (MDA) content,and expression of activated caspase-3 (using immunohistochemistry and Western blot analysis) and for detection of cell apoptosis in hepatic tissues.Apoptotic index was calculated.Results Compared with group S,the serum ALT and AST activities,MDA content and apoptotic index were significantly increased,SOD activity was decreased,and the expression of activated caspase-3 was up-regulated in I/R,R1,R2 and R3 groups.Compared with group I/R,no significant changes were found in the indexes mentioned above in group I/R,and the serum ALT and AST activities,MDA coment and apoptotic index were significantly decreased,SOD activity was increased,and the expression of activated caspase-3 was down-regulated in R2 and R3 groups.Conclusion Remifentanil preconditioning can reduce hepatic I/R injury in rats with liver cirrhosis,and the mechanism is related to inhibition of the lipid peroxidation and cell apoptosis.

OBJECTIVETo investigate the metabolic profile of hydrocortisone-induced 'Kidney-yang deficiency syndrome'in rats and the intervention effects of Morinda officinalis.

METHODProton nuclear magnetic resonance (1H-NMR) technique was used to analyze the rat metabonome in serum. Orthogonal partial least squares discriminant analysis (OPLS-DA) were processed to analyze the metabonome difference between the control and hydrocortisone treated samples. Twelve potential biomarkers were selected, via the parameter of variable importance in the projection (VIP). Principal components analysis (PCA) was employed to process the data from the M. officinalis. treatment group and the intervention effects of M. officinalis, was investigated through the selected potential biomarkers.

RESULTAfter hydrocortisone treatment, the energy metabolism, amino acids metabolism and gut microflora environment were seriously disturbed and transmethylation was surpressed. M. officinalis could effectively alleviate the disturbance of energy and amino acids metabolism and enhance transmethylation, but could not modulate the gut microflora environment.

CONCLUSIONThe results obtained suggested that metabonomic studies could better reflect the whole status of metabolism in bio-systems, and could be treated as a potential powerful approach in pharmacological studies and investigation of the essence of 'syndrome' in traditional Chinese medicine.
