Objective To investigate the effect of Dapagliflozin on high glucose-induced podocyte proliferation and apoptosis through p38 mitogen-activated protein kinase(p38 MAPK)pathway.Methods Human glomerular podocytes(HGPC)were divided into control(Con)group,low/medium/high D-glucose(Glu 10,Glu 20,Glu 30)group,high glucose(HG)group,low/medium/high concentration Dapagliflozin(HG+Dap 12.5,HG+Dap 25,HG+Dap 50)group,Dapagliflozin(HG+Dap)group,inhibitor(HG+ SB 203580)group,Dapagliflozin + inhibitor(HG+Dap+SB 203580)group and Dapagliflozin + activator(HG+Dap+C16-PAF)group.After 24 hours of intervention,the cell viability,proliferation rate,apoptosis rate and levels of related factors were tested.Results Compared with Con group,IL-1β,TNF-α,apoptosis rate,Caspase-3 mRNA and protein expression,p53,p-p38 MAPK protein expression were increased(P＜0.05),while cell proliferation rate,Cyclin D1 mRNA and protein expression were decreased in HG group(P＜0.05).Compared with HG group,the proliferation rate,Cyclin D1 mRNA and protein expression were increased(P＜0.05),while IL-1β,TNF-α,apoptosis rate,Caspase-3 mRNA and protein expression,p53,p-p38 MAPK protein expression were decreased in the HG+Dap and HG+SB 203580 groups(P＜0.05).Compared with HG+Dap group,cell proliferation rate,Cyclin D1 mRNA and protein expression were increased(P＜0.05),while IL-1β,TNF-α,apoptosis rate,Caspase-3 mRNA and protein expression,p53,p-p38 MAPK protein expression were decreased in HG+Dap+SB 203580 group(P＜0.05).In HG+Dap+C16-PAF group,IL-1β,TNF-α,apoptosis rate,Caspase-3 mRNA and protein expression,p53,p-p38 MAPK protein expression were increased(P＜0.05),while cell proliferation rate,Cyclin D1 mRNA and protein expression were decreased(P＜0.05).Conclusion Dagagliflozin can promote HGPC proliferation and inhibit apoptosis and inflammation in high D-glucose environment,and its mechanism may be related to the inhibition of p38 MAPK pathway signal transduction.

Standardized reporting is a crucial factor affecting the use of patient guidelines （PGs）， particularly in the reporting and presentation of recommendations. This paper introduced the current status of PG reporting， including the research on PG content and presentation formats， and provided comprehensive recommendations for PG reporting from aspects such as overall framework， recommendations， presentation format， and readability. First， the presentation of PG recommendations should include clearly defined clinical questions， recommendations and their rationale， and guidance on how patients should implement the interventions； for specific content in the PG， such as level of evidence， level of recommendation， it is recommended to explain in text the reasons for giving different levels of recommendation， i.e.， to present the logic behind giving the level of recommendation to the patient； additional information needed in the recommendation framework should be supplemented by tracing references or authoritative textbooks and literature that support the recommendations. Subsequently， the PG text should be written based on the Reporting Checklist for Public Versions of Guidelines （RIGHT-PVG） reporting framework. Finally， to enhance readability and comprehension， it is recommended to refer to the Patient Education Materials Assessment Tool （PEMAT） for translating PG content. To enhance the readability of PGs， it is suggested to present the PG content in a persona-lized and layered manner.

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.

Objective: To investigate the association between 24 h movement behaviors (physical activity, sleep, and screen time) and fundamental motor skills (FMS) in preschool children, in order to provide the reference and basis for ensuring the longterm development of childrens motor skills. Methods: A total of 607 children aged 3 to 5 years old were selected from 6 kindergartens of 6 urban districts in Taiyuan in March 2022, through a combination of convenient sampling and stratified cluster random sampling method, and the baseline test was conducted to collect data on the childrens 24 h movement behaviors and FMS; the followup test after one year was carried out in March 2023 to collect FMS data. The test of gross motor development-3rd was used to assess the childrens FMS levels. Physical activity and sleep duration were measured using ActiGraph GT3X+ accelerometers, while screen time was reported by parents. Pearson correlation analysis, hierarchial and binary Logistic regression analyses were used to analyze the association of 24 h movement behavior with FMS. Results: The results of baseline showed that total of physical activity (TPA) at baseline was positively associated with manipulation skills, mobility skills and total score of TGMD-3 (β=0.40, 3.87, 4.27, P<0.01). The followup results after one year indicated that lowintensity physical activity (LPA) and screen time at baseline were negatively associated with increased TGMD-3 scores one year later (β=-1.93, -0.79, P<0.01). Conversely, baseline moderatetovigorousintensity physical activity (MVPA), TPA and sleep duration were positively associated with increased TGMD-3 scores after one year (β=4.62, 4.51, 3.19, P<0.01). The followup results showed that meeting 2 or 3 items of the 24 h movement behavior guidelines was significantly associated with an increased likelihood of achieving motor skill proficiency (OR=2.31, 3.32, P<0.01) compared to not meeting any 24 h movement behavior guideline after one year. Conclusions MVPA and enough sleep could positively affect FMS improvement, whereas LPA and long screen time could negatively affect FMS improvement at one year followup. Schools and families should ensure that preschool children meet the recommended standards of the 24 h movement behavioral guidelines to promote longterm development of FMS.

In recent years， the potential anti-tumor effects of metformin have attracted widespread attention in the field of cancer treatment. This article summarizes the research progress of metformin in the treatment of malignant tumors，finding its potential application in the treatment of malignant tumors in the digestive system （biliary tract cancer，gastric cancer，esophagus cancer，colorectal cancer，pancreatic cancer，liver cancer） and reproductive system （prostate cancer，ovarian cancer，breast cancer， cervical cancer），non-small cell lung cancer，renal cell carcinoma，and melanoma. Metformin can inhibit the proliferation of tumor cells and extend the overall survival of patients. Its mechanisms of action include，but are not limited to，inhibiting the activity of mitochondrial complex Ⅰ，activating adenosine monophosphate-activated protein kinase/p53 signaling pathway，and blocking the cell cycle. Additionally，the combined use of metformin with chemotherapy drugs has shown potential for reducing toxicity and enhancing efficacy. It can enhance the sensitivity of biliary tract cancer，ovarian cancer，and melanoma cells to chemotherapy drugs， improve the drug resistance of gastric and colorectal cancer cells to chemotherapy，and reduce the toxic reactions of breast cancer patients during chemotherapy. Metformin is also used as an immunomodulator，applied in the immunotherapy of patients with esophagus cancer，colorectal cancer，cervical cancer，non-small cell lung cancer，and melanoma.

Objective:To compare the surgical outcomes of robotic natural orifice specimen extraction surgery (NOSES) and robotic-assisted radical resection for rectal cancer.Methods:A retrospective analysis using propensity score matching (PSM) was conducted on 547 patients who had undergone radical resection of rectal cancer at the First Affiliated Hospital of Nanchang University from June 2018 to March 2024. The study cohort comprised 157 patients in the robotic NOSES group and 390 in the robotic-assisted group. PSM was used in a 1:1 manner to match relevant general clinical preoperative data of the study patients (age, sex, body mass index, preoperative comorbidities, abnormal preoperative carcinoembryonic antigen (>6.5 μg/L) and carbohydrate antigen 19-9 levels (>27 kU/L), preoperative American Society of Anesthesiologists score, tumor diameter, tumor distance from the anal margin, and TNM stage), with a clamp value of 0.05. After performing PSM to match the general clinical data of the two groups of patients, 77 patients in each of the robotic NOSES and robotic-assisted groups were included in the analysis. We found no statistically significant difference in preoperative general clinical data between the robot NOSES and robot-assisted groups ( P>0.05). We compared the surgical outcomes, postoperative recovery, postoperative pathological data, and incidence of complications between the robotic NOSES and robot-assisted groups. Results:Compared with the robot-assisted groups. the robot NOSES group had a significantly shorter time to first postoperative passage of flatus (48 [38, 50] hours vs. 56 [50, 60] hours, Z=-7.513, P<0.001), time to taking a liquid diet (60 [54,63] hours vs. 66 [62, 72] hours, Z=-6.303, P<0.001), lower pain scores (3 [3, 4] vs. 4 [4, 5], Z=-5.237, P<0.001), and lower incision infection rates (0 vs. 5 [6.5%], χ 2=5.237, P=0.028) within 24 hours after surgery ( P<0.05). However, there were no significant differences in surgical time, intraoperative blood loss, postoperative hospital stay, postoperative anastomotic complications, or incidence of other complications between the two groups (all P>0.05). Conclusion:Robotic NOSES surgery is a safe and feasible procedure for resecting rectal cancer and postoperative recovery is faster after robotic NOSES than after standard robot-assisted surgery.
