Recommendation formation is a key component of clinical practice guidelines for Chinese patent medicine （CPM）， and should encompass the determination of the strength and direction of the recommendation， the rationale for the recommendation， and the methodology for implementing the recommendation. Recommendations can be formed through formal consensus and informal consensus. The strength and direction of recommendations for CPM guidelines should be determined by considering the quality of evidence for CPMs， the priority of the clinical questions， the pros and cons of efficacy and adverse effects， patient acceptance， the feasibility of the recommendation and the availability of resources， social fairness， economic benefits， and other influencing factors. In order to better guide guideline developers to consider these factors more rationally， this article provideed a detailed explanation of each factor in the context of the characteristics of TCM.

Objective:To understand the relationship between unhealthy lifestyle and hyperuricemia, as well as the modification effects of hypertension and dyslipidemia in occupational population and provide a theoretical basis for the prevention of hyperuricemia.Methods:A cross-sectional survey design was adopted, based on baseline data from the Southwest Occupational Population Cohort from China Railway Chengdu Group Co., Ltd., which included the population in 28 prefectures from Sichuan Province and Guizhou Province, and 33 districts (counties) from Chongqing Municipality between October and December 2021. This study collected the information about the demographics characteristics, lifestyles, and prevalence of chronic non-communicable diseases of the study subjects through questionnaire, physical measurement and laboratory biochemical test. The unhealthy lifestyle score was scored based on smoking, alcohol consumption, dietary patterns, physical activity, and low weight or overweight, with higher scores being associated with more unhealthy lifestyles. The multivariate logistic regression model was used to analyze the relationship between unhealthy lifestyle score, smoking, alcohol consumption, other factors and hyperuricemia, and the stratified analysis was used to explore the modification effect of hypertension and other diseases on the relationship between unhealthy lifestyle and hyperuricemia.Results:A total of 11 748 participants were included in this study, the prevalence of hyperuricemia was 34.4%. Multivariate logistic regression model showed that current/previous smoking, current/previous alcohol consumption and BMI abnormality were risk factors for hyperuricemia, and the unhealthy lifestyle score showed a "cumulative" effect on the risk for hyperuricemia, with higher score increasing the risk of hyperuricemia, and the OR increased from 1.64 (95% CI: 1.34-2.00) to 2.89 (95% CI: 2.39-3.50). Stratified analysis showed that unhealthy lifestyles had a greater impact on the risk for hyperuricemia in people with hypertension and dyslipidemia. Conclusions:The coexistence of multiple unhealthy lifestyles might increase the risk of hyperuricemia, and this effect was stronger in participants with hypertension and dyslipidemia. Timely correction of unhealthy lifestyles, and control of hypertension and dyslipidemia might reduce the risk for hyperuricemia.

Objective To construct a Type 1 diabetes model in miniature pigs and explore postoperative care strategies for effectively prolonging the survival time of the model pigs.Methods Seven Banna miniature pigs were selected for pancreatectomy.Glucose,vitamins,and antibiotics were administered for 3-5 days after surgery to aid recovery.Blood glucose and urine glucose levels were measured twice a day in the morning and evening to adjust insulin supplementation accordingly.The model pigs were observed daily and records were kept,including orexis,psychosis,weakness,skin ulcer,and feces and urine.Body weight was measured weekly until the death of the model animals.Based on the model pigs'condition,glucose injection and Ringer's lactate solution were administered to supplement nutrition and correct electrolyte imbalances.Results All seven Banna miniature pigs showed typical symptoms of diabetes:random blood glucose levels higher than 11.1 mmol/L after pancreatectomy,far exceeding the average blood glucose level of 6.0 mmol/L in normal pigs;positive urine glucose;and progressive weight loss.These features indicated the successful construction of Type 1 diabetes model.Additionally,Type 1 diabetic pigs that survived more than 8 weeks showed progressive hair loss and skin ulceration.Euthanasia was performed on model pigs when they were unable to stand or even eat independently,and pathological examination and HE staining were conducted on tissues collected from affected organs such as the liver,kidneys,and skin.Pathological sections revealed liver congestion,massive glycogen accumulation,ballooning degeneration of hepatocytes,and progressive liver fibrosis,along with glomerular congestion,vacuolar degeneration in renal tubular epithelial cells,proteinuria,dermal congestion,thinning of vascular walls,and varying degrees of parakeratosis and dyskeratosis in the liver,kidneys,and skin tissues due to prolonged hyperglycemia.The average survival time of the constructed Banna miniature pig diabetes model was 44 d,with a maximum survival time of 121 d.Conclusion Type 1 diabetes model can be constructed successfully in Banna miniature pigs through pancreatectomy.With meticulous postoperative care,a long-term Type 1 diabetes model with significant complications can be achieved,providing a stable large-animal model for Type 1 diabetes treatment strategies.

Objective:To discuss the anti-inflammatory and antioxidant effect of mesalazine(MSZ)in the RAW264.7 cell model,and to elucidate its therapeutic effect on periodontitis in the rats.Methods:The proliferation rates of RAW264.7 cells stimulated by different concentrations(0,62.5,125.0,250.0,500.0,1 000.0,and 2 000.0 mg·L-1)of MSZ were detected by CCK-8 method to determine the optimal concentration of MSZ for cell treatment.Porphyromonas gingivalis lipopolysaccharide(P.g-LPS)and MSZ were used to treat the RAW264.7 cells,and the cells were divided into control group,P.g-LPS group,and MSZ+P.g-LPS group.The levels of reactive oxygen species(ROS)in the cells in various groups were detected by the DCFH-DA fluorescent probe assay;the malondialdehyde(MDA)levels,glutathione(GSH)levels and superoxide dismutase(SOD)activities in the cells in various groups were detected by ELISA method;the expression levels of inflammatory factors interleukin-8(IL-8)and interleukin-1β(IL-1β)mRNA in the cells in various groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)method.The periodontitis rat model was established by the ligation method combined with the injection of P.g bacterial fluid.A total of 18 rats were randomly divided into control group(without treatment),model group(making period ontits model),and drug administration group(making periodontits model and given MSZ),and there were 6 rats in each group.Micro-CT was used to assess the alveolar bone destruction of the rats in various groups;HE staining was used to observe the morphology of periodontal tissue of the rats in various groups.Results:Compared with control group,the proliferation rate of the cells in 500.0 mg·L-1 MSZ group was significantly increased(P＜0.01),so 500.0 mg·L-1 MSZ was subsequently selected to treat the cells.Compared with control group,the levels of ROS and MDA in the cells in P.g-LPS group were significantly increased(P＜0.01),and the level of GSH and activity of SOD were significantly decreased(P＜0.01),and the expression levels of IL-1β and IL-8 mRNA were significantly increased(P＜0.01);compared with P.g-LPS group,the levels of ROS and MDA in the cells in MSZ+P.g-LPS group were significantly decreased(P＜0.01),the level of GSH and activity of SOD were significantly increased(P＜0.01),and the expression levels of IL-1β and IL-8 mRNA were significantly decreased(P＜0.01).The micro-CT assay results showed that compared with control group,the distance from the cemento-enamel junction to alveolar bone crest(CEJ-ABC)of the rats in model group was significantly increased(P＜0.01),and the bone volume fraction(BV/TV)was significantly decreaced(P＜0.05);compared with model group;the CEJ-ABC of the rats in drug administration group was decreased(P＜0.01),and the BV/TV was increased(P＜0.05).The HE staining results showed that the inflammatory cell infiltration in periodontal tissue of the rats in drug administration group was reduced,and epithelial attachment was restored.Conclusion:MSZ effectively inhibits the production of pro-inflammatory factors and peroxides in the P.g-LPS-induced RAW264.7 cells,improves the cellular anti-inflammatory and antioxidant capacity,inhibits the alveolar bone resorption,and alleviates the inflammation of periodontal tissues in the periodontitis rats.

Objective To investigate the role of TLR4/NF-κB signaling pathway in mediating sleep depriva-tion induced endolymphatic hydrops.Methods A total of 30 healthy sprague-dawley(SD)rats were randomly di-vided into the control group、big platform control group,and 2 w,3 w,4 w sleep deprivation group,with 6 rats in each group.Modified multiple platform method was adopted to establish the rat sleep deprivation model.Before and after the experiment,the open field and acoustic brain-stem response(ABR)was conducted to evaluate the behavior and hearing level.After ABR test,blood samples were collected from abdominal aorta,and serum levels of TNF-αand MCP-1 were detected by ELISA.The cochlea was dissected,the severity of endolymphatic hydrops was as-sessed by calculating the ratio of the cross sectional area of the membranous cochlear duct(SM)to that of the mem-branous cochlear duct+scale vestibuli(SM+SV).Positive expression of IL-1β,TNF-α,MCP-1,TLR4,NF-κB P65 in rat cochlear tissues was detected via immunohistochemical staining.After the experiment,the changes of hearing level,the severity of endolymphatic hydrops and TLR4/NF-κB signaling pathway related proteins and down-stream inflammatory factors expression level were observed.The correlation between TLR4/NF-κB signaling path-way and hearing level and endolymphatic hydropsin rats was analyzed.Results ABR results showed an increased threshold of wave Ⅱ in the sleep deprivation group compared to those of the control group and big platform control group(P＜0.05).The rate of hydrops was 0％in control and big platform control groups,16.67％in 2w sleep deprivation group and 25％in 3 w and 4 w sleep deprivation group.The concentrations of TNF-αand MCP-1 in ser-um of rats in sleep deprivation groups were higher than those in control and big platform control groups,and the 4w sleep deprivation group were statistically significant compared with control and big platform control groups.The ex-pressions of IL-1β,TNF-α,MCP-1,TLR4 and NF-κB P65 in the cochlear spiral ganglion,spiral canal,stria vascu-laris and spiral ligament of rats in sleep deprivation groups were higher than those in control and big platform control groups.Conclusion Sleep deprivation may induce endolymphatic hydrops by the TLR4/NF-κB signaling pathway.

Objective To investigate the feasibility of robotic-assisted"3+1"surgical mode strategy for the treatment of median arcuate ligament syndrome(MALS).Methods Six patients diagnosed as MALS were enrolled between June 2019 and October 2023.The utilization of robotic-assisted"3+1"surgical mode(a 4-hole operation with 3 robot arms and 1 assistance hole)was carried out.Through a posterior splenic artery approach,the compression of the midline arcuate ligament on the abdominal trunk was relieved,which was an abdominal trunk vascularization.Results All the 6 patients underwent robotic-assisted"3+1"surgical mode successfully.The surgical duration(including the time for connecting and disconnecting the machine)was 38-52 min,with a mean of 43.2 min.The intraoperative bleeding volume was 5-25 ml,with a mean of 15 ml.The postoperative hospital stay was 6-9 d,with a mean of 7.5 d.All the 6 patients were followed up for 1-45 months after surgery(median,2.5 months).One patient remained unchanged in body weight,while 5 patients gained 1.0-2.0 kg in body weight,with a mean of 1.5 kg.The symptom of postprandial epigastric pain completely resolved in 5 patients,while the symptom was reduced but not completely alleviated in one patient.Conclusion Treatment of MALS with the robotic-assisted"3+1"surgical model involving abdominal trunk vascularization through a posterior splenic artery approach is safe and feasible.

OBJECTIVE: To investigate the effectiveness of three-dimensional (3D)-printed hemi-pelvic prosthesis for revision of aseptic loosening or screw fracture of modular hemi-pelvic prosthesis. METHODS: Between February 2017 and January 2020, 11 patients with aseptic loosening or screw fracture of modular hemi-pelvic prosthesis were revised using 3D-printed hemi-pelvic prostheses. There were 7 males and 4 females with an average age of 44 years (range, 25-60 years). In the first operation, all patients underwent total tumor resection, modular hemi-pelvic prosthesis reconstruction, and autologous femoral head transplantation. According to the Enneking pelvic partition system, 8 cases were resected in zones Ⅰ+Ⅱ and 3 cases in zones Ⅰ+Ⅱ+Ⅲ. The interval from the initial operation to this revision ranged from 14.3-66.2 months, with an average of 35.8 months. The operation time, the amount of intraoperative bleeding, and the occurrence of complications were recorded. At 6 months after the first operation, before revision, and at last follow-up, the American Musculoskeletal Tumor Society (MSTS) score and Harris score were used to evaluate the recovery of lower limb function. The pain-free walking distance of patients without brace assistance was recorded at last follow-up. X-ray films were taken at 1 month after the first operation, before revision, and at 1 month after revision, the acetabulum position was assessed by the differences in weight arm and cup height between bilateral hip joints. At last follow-up, the digital X-ray tomography was taken to evaluate the prosthesis-bone integration and the occurrence of aseptic loosening. RESULTS: The operation time was 182.6-238.0 minutes (mean, 197.4 minutes). The amount of intraoperative bleeding was 400-860 mL (mean, 550.0 mL). All incisions healed by first intention with no infection, hip dislocation, nerve damage, or vascular-related adverse events. The MSTS score and Harris score at last follow-up were significantly higher than those at 6 months after the first operation and before revision ( P<0.05), while the score before revision was significantly lower than that at 6 months after the first operation ( P<0.05). At last follow-up, the patients were able to walk more than 1 000 meters painlessly without brace assistance. Imaging review showed that the difference of cup height at 1 month after revision was significantly lower than that at 1 month after the first operation and before revision, and at 1 month after the first operation than before revision operation, and the differences were significant ( P<0.05). There was no significant difference in the difference of weight arm among three time points ( P>0.05). All prostheses were well integrated, and no aseptic loosening of the prosthesis or screw fracture occurred. CONCLUSION Revision with 3D-printed hemi-pelvic prostheses benefited in reconstructing stable pelvic ring and natural bodyweight transmission for patients encountering the aseptic loosening or screw fracture of modular hemi-pelvic prosthesis. Early postoperative rehabilitation training can maximize the recovery of patient limb function, reduce pain during walking, and reduce the incidence of complications.
