Since the concept of patient versions of guidelines （PVGs） was introduced into China， several PVGs have been published in China， but we found that there is a big difference between the concept of PVG at home and abroad， and the reason for this difference has not been reasonably explained， which has led to ambiguity and even misapplication of the PVG concept by guideline developers. By analyzing the background and purpose of PVGs， and the understanding of the PVG concept by domestic scholars， we proposed the term patient guidelines （PGs）. This refers to guidelines developed under the principles of evidence-based medicine， centered on health issues that concern patients， and based on the best available evidence， intended for patient use. Except for the general attribute of providing information or education， which is typical of common health education materials， PGs also provide recommendations and assist in decision-making， so PGs include both the patient versions of guidelines （PVG） as defined by the Guidelines International Network （GIN） and "patient-directed guidelines"， i.e. clinical practice guidelines resulting from the adaptation or reformulation of recommendations through clinical practice guidelines.

At present， the process and methodology of patient guidelines （PGs） development varies greatly and lacks systematic and standardised guidance. In addition to the interviews with PG developers， we have sorted out the relevant methodology for the adaptation and development of existing clinical practice guideline recommendations and facilitated expert deliberations to achieve a consensus， so as to finally put forward a proposal for guidance on the process and methodology for the development of PGs. The development of PGs can be divided into the preparation stage， the construction stage， and the completion stage in general， but the specific steps vary according to the different modes of development of PGs. The development process of Model 1 is basically the same as the patient version of the guideline development process provided by the International Guidelines Network， i.e.， team formation， screening of recommendations， guideline drafing， user testing and feedback， approval and dissemination. The developer should also first determine the need for and scope of translating the clinical practice guideline into a patient version during the preparation phase. Model 2 adds user experience and feedback to the conventional clinical practice guideline development process （forming a team， determining the scope of the PG， searching， evaluating and integrating evidence， forming recommendations， writing the guideline， and expert review）. Based on the different models， we sort out the process and methods of PG development and introduce the specific methods of PG development， including how to identify the clinical problem and how to form recommendations based on the existing clinical practice guidelines， with a view to providing reference for guideline developers and related researchers.

Clinical trials play a crucial role in advancing the field of human health care. The registration of clinical trials can effectively identify potential publication bias and prevent unnecessary duplication of research efforts, serving as a source of transparent data for health care professionals and researchers, enhancing the quality of clinical research, and presenting more transparent, standardized, authentic, and useful clinical trials. To enhance the capacity for evidence production in traditional medicine from the source, the International Traditional Medicine Clinical Trial Registry (ITMCTR), a cross-regional registry focusing on the theme of traditional medicine, was established. Under the current registration background, this study aims to introduce the problems and current status related to clinical trial registration, as well as the features and functions of the ITMCTR. The results of this study illustrate the necessity of establishing a specialized registration platform for traditional medicine to assist researchers in understanding the basic background of registration and relevant information regarding registration platforms, regardless of whether their research is related to traditional medicine or not. Ultimately, the results of this work will help researchers choose the appropriate platform for more efficient and transparent registration.

Objective To investigate the relationship between symptom burden and rehabilitation self-efficacy of patients after fragility fracture surgery,and to study the chain mediating role of social support and perceived stress in the influence of symptom burden on rehabilitation self-efficacy of such patients.Methods Approved by the Ethics Committee of the hospital,168 patients who met the admission criteria after fragility fracture surgery admitted to the Second Affiliated Hospital of Inner Mongolia Medical University from July 2020 to December 2023 were included in the study by convenient sampling method,and general data of the patients were collected.M.D.Anderson Symptom Inventor(MDASI),Self-Efficacy for Managing Chronic Disease 6-Item Scale(SECD6),Social Support Rating Scale(SSRS)and Perceived Stress Scale(CPSS)were used to investigate the above patients,and multiple sets of quantitative data were analyzed for attribution association profile and mediation effect.Results After removing invalid questionnaires,a total of 160 valid questionnaires were collected,with an effective response rate of 95.24％.Correlation analysis showed that symptom burden was negatively correlated with rehabilitation self-efficacy(r=-0.405,P＜0.05);social support was significantly positively correlated with rehabilitation self-efficacy(r=0.558,P＜0.05);perceived stress was negatively correlated with rehabilitation self-efficacy(r=-0.330,P＜0.05);symptom burden was negatively correlated with social support(r=-0.191,P＜0.05);social support was negatively correlated with perceived stress(r=-0.280,P＜0.05);symptom burden was positively correlated with perceived stress(r=0.376,P＜0.05).Mediating effect test showed that the symptom burden of patients after fragility fracture surgery had a direct impact on rehabilitation self-efficacy(β=-0.402,t=0.148,P＜0.05),and had an impact on rehabilitation self-efficacy through 3 mediating pathways:first,the mediating effect of social support alone(β=-0.098,95％CI:-0.112～-0.074);the second was the mediating effect of stress perception alone(β=-0.081,95％CI:-0.104～-0.061);the third is the chain mediating effect of social support and stress perception(β=-0.056,95％CI:-0.074～-0.030).Conclusion The burden of symptoms after fragility fracture surgery has a direct effect on rehabilitation self-efficacy.Symptom burden influences postoperative self-efficacy of patients with fragility fractures through the chain mediation of social support and perceived stress.Early and accurate assessment of symptom burden,stress perception and social support should be conducted.According to needs,the multidisciplinary medical team provides individualized and diversified health education support to actively help and guide the self-regulation of patients'stress perception,so as to reduce patients'symptom burden and promote the improvement of their self-efficacy in the process of rehabilitation.

Objective:To retrospectively analyze the characteristics and influencing factors of liver function changes in 111 elderly patients with COVID-19 pneumonia.Methods:111 elderly patients with COVID-19 admitted to the Department of Infectious Diseases, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from February 5 to March 3, 2020 were enrolled. According to the severity of disease and liver function condition, they were divided into severe group ( n=40), normal group ( n=71), abnormal liver function group ( n=86) and normal liver function group ( n=25). The indexes related to liver function changes [total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and γ-glutamyl transferase (GGT)] and related influencing factors were analyzed. Results:Among 111 cases, 86 (77.5%) had abnormal liver function of varying degrees, and 28 (25.2%) had liver injury. The abnormal rates of TBil, AST, ALP and GGT were significantly higher in the severe group than normal group ( P<0.05). There were no significant differences in age, ribavirin, glucocorticoid and the application of lopinavir-ritonavir tablets between the abnormal liver function and the normal group ( P>0.05). The proportion of male was significantly higher in the abnormal liver function than normal liver function group ( P<0.05). Conclusion:Elderly COVID-19 patients have a higher proportion of abnormal liver function, and patients in the severe group are more likely to have higher level of TB, AST, ALP and GGT. The abnormal liver function may be related to the direct viral infection of the liver and the inflammatory immune response of the body after infection in elderly patients.

Objective To investigate the prevalence of Spirometra mansoni infections in hosts in Jiangsu Province, so as to provide the scientific basis for the management of sparganosis mansoni. Methods From 2018 to 2019, nine counties (cities, districts) were randomly selected from Jiangsu Province as the survey sites, and 100 healthy individuals were randomly selected to perform the serological test of S. mansoni infections and the detection of S. mansoni eggs. The procercoids were detected in the intermediate host Cyclops, and the S. mansoni eggs were identified in the stool samples of the definitive hosts cats and dogs. Results The prevalence of S. mansoni human infections was 0 (0/900) in the 9 survey sites of Jiangsu Province, and the sero-prevalence of the specific IgG antibody against S. mansoni was 1.22% (11/900). The positive rate of procercoids was 0.33% (3/900) in Cyclops. In addition, the S. mansoni egg-positive rate was 1.48% (2/135) in cats and dogs. Conclusions Sparganosis mansoni is prevalent in Jiangsu Province. Health education pertaining to the damages of sparganosis mansoni and the route of S. mansoni infections should be improved.

Objective: To validation and optimization the indicator system of risk assessment for mechanical cuts. Methods: The risk assessment index system of mechanical cutting injury established earlier was used to assess the risk of mechanical cutting injury in 40 cases of mechanical cutting injury registered from January 2015 to December 2017 and 40 similar positions without accidents in the same period. The multiple stepwise regression analysis was used to screen the indicator system, and to adjust the weight coefficient of each index. The total coincidence rate and Kappa value were compared between before and after optimization respectively. Results: The new index system has 3 first-class indicators, 10 second-class indicators and 14 three-class indicators, fewer than the old index system which has 3 first-class indicators, 10 second-class indicators, 34 three-class indicators. There three indicators have revamped in the first-class. The total of coincidence rates of the new and old indicator systems were 67.50% and 90.00%, the difference was statistically significant (P<0.01). The Kappa value were 0.35 and 0.80, respectively. Conclusion The evaluation results with new indicator systems is more consistent with the actual hazard detection the the old indicator systems, and scientific, reasonable and practical, and the indicator system of risk assessment for mechanical cuts can be used for the risk assessment of mechanical cutting injuries.

ObjectiveTo explore the clinical selection and application of cell suspension examination (CSE) or histopathological technique (HPT) in detecting sperm in the testis tissue obtained by testicular sperm aspiration (TESA) in patients with non-obstructive azoospermia (NOA).

METHODSTotally, 1 006 NOA patients underwent TESA and their testis tissues were subjected to CSE or HPT for sperm detection. Based on the results of CSE, the testicular tissue samples were divided into groups A (with sperm, n = 567) and B (without sperm, n = 439) and the results were compared with those of HPT.

RESULTSHPT showed 508 cases with but 59 without sperm in group A, and 403 with and 36 without sperm in group B. The consistency rate of CSE with that of HPT was 90.56% (Kappa =0.809), and CSE exhibited a significantly higher rate of sperm detection than HPT (56.36% vs 54.08%, P=0.023).

CONCLUSIONSCSE combined with HPT for detecting sperm in the testis tissue of NOA patients undergoing diagnostic TESA helps clinical diagnosis and treatment. The results of CSE have a decisive significance for assisted reproductive therapy, while those of HPT may provide some definite etiological evidence for drug therapy or surgery.

Objective To investigate the roles of RU486 inhibiting 3T3-L1 pre-adipocytes differentiation and regulating NF-κB activation. Methods Cells were treated with RU486 with concentrations of 0.1 ~ 10μmol/L for 48 h , then the relative contents of triglyceride were analyzed by Oil-Red O staining assay on 9 th day during adipogenesis. The mRNA expressions of PPARγ2,C/EBPa, LPL and FAS were further measured by Real-time PCR. IκBα protein level was detected by Western bolt and nuclear translocation of NF-κB was observed by immunofluorescence assay. Results The relative contents of triglyceride decreased with the increasing of RU486 concentration. Compared with the control, the relative contents of triglyceride in RU486-treatment groups from 0.5 μmol/L were significantly decreased (P < 0.05 or P < 0.01). Compared with the control, PPARγ2, C/EBPa, LPL and FAS mRNA expression and IκBα protein level were significantly decreased (P < 0.01) and NF-κB nuclear translocated from cytoplasm to nucleus in Group 5 mmol/L RU486. Conclusions RU486 could down regulate IκBα protein level , activate NF-κB nuclear translocation , then down regulate PPARγ2 , C/EBPa , LPL and FAS mRNA expression and inhibit adipocytes differentiation.
