Objective To explore the relationship and internal path between activities of daily living(ADL),sleep quality and mental health of community elderly people in Shanghai.Methods A questionnaire survey was conducted among community residents aged 60 years and older seeing doctors in community health care center of five streets in Shanghai during Sept to Dec,2021 using convenience sampling.Activities of Daily Living(ADL),Pittsburgh Sleep Quality Index(PSQI)and 10-item Kessler Psychological Distress Scale(K10)were adopted in the survey.Single factor analysis,correlation analysis and multiple linear regression were used to analyze the data.The effect relationship between the variables was tested using Bootstrap's mediated effects test.Results A total of 1 864 participants were included in the study.The average score was 15.53±4.47 for ADL,5.60±3.71 for PSQI and 15.50±6.28 for K10.The rate of ADL impairment,poor sleep quality,poor and very poor mental health of the elderly were 23.6%,27.3%,11.9%and 4.9%,respectively.ADL and sleep quality were all positively correlated with mental health(r=0.321,P＜0.001;r=0.466,P＜0.001);ADL was positively correlated with sleep quality(r=0.294,P＜0.001).Multiple linear results of factors influencing mental health showed that ADL(β= 0.457,95%CI:0.341-0.573),sleep quality(β =0.667,95%CI:0.598-0.737)and mental health were positively correlated(P＜0.001).Sleep quality partially mediated the relationship between ADL and mental health(95%CI:0.078-0.124)with an effect size of 33.0%.Conclusion Sleep quality is a mediator between ADL and mental health among community elderly people.Improving ADL and sleep quality may improve mental health in the population.

Objective To investigate the application value of single nucleotide polymorphism(SNP)linkage analysis based on next-generation sequencing(NGS)technology in preimplantation genetic testing(PGT)of families with autosomal recessive polycystic kidney disease(ARPKD).Methods A family with ARPKD was selected,where the female member had a pregnancy ultrasound revealing polycystic kidney in the fetus.Genetic testing showed compound heterozygous mutations of the polycystic kidney/polycystic liver disease 1 gene(PKHD1),c.10444C>T(paternal)and c.4303del(maternal),with the c.4303del mutation being reported for the first time.Targeting the coding region of the PKHD1 gene,335 high-density tightly linked SNP sites were selected in the upstream and downstream 2M regions using multiplex polymerase chain reaction(PCR)and NGS.The couple′s SNP risk haplotypes carrying gene mutations were constructed.After in vitro fertilization,blastocyst culture was performed.Trophoblastic cells obtained from the biopsy were subjected to whole-genome amplification,and NGS was used for linkage analysis and low-depth chromosomal aneuploidy screening of the embryos.Sanger sequencing was used to verify the results of embryo linkage analysis.Results Among the 6 biopsied embryos,4 were mutation-free and euploid,1 exhibited heterozygous for the mutation and mosaic while another unstable sequencing data,making it impossible to judge.One of the mutation-free and developmentally healthy euploid embryos was implanted into the maternal uterus,resulting in the full-term delivery of a healthy baby.Conclusion Application of NGS-based SNP linkage analysis in PGT can effectively blocking the vertical transmission of ARPKD within families,while avoiding abortion issues caused by aneuploid embryos.This study is also the first PGT report target-ing the PKHD1 gene c.4303del mutation.

Objective:To analyze and predict the future trend of the premature mortality of major chronic and non-communicable diseases in Anhui Province, evaluate the implementation of the "Healthy China 2030" Plan, and explore its influencing factors.Methods:Using data from death-cause surveillance and statistical yearbooks in Anhui, the trend prediction and analysis on influencing factors were conducted by using methods such as time series accumulation and logarithmic linear Joinpoint regression, principal component regression.Results:In Anhui, 28.10% of the deaths were premature ones, of which 84.40% were attributed to chronic and non-communicable diseases. In premature deaths attributed to chronic and non-communicable diseases, the deaths caused by malignant tumor and cardiovascular disease accounted for 45.88% and 41.65% respectively. The prediction results showed that the premature mortality of major chronic and non-communicable diseases would decrease in Anhui in the future, and by 2030, the goal in the "Healthy China 2030" Plan would be reached only in rural area. To reduce premature death, it is necessary to pay attention to the prevention and control of malignant tumor and cardiovascular disease. Men in urban area are the key population. Factors that reflect urban infrastructure had a significant impact on premature mortality of major chronic non-communicable diseases, such as garden and green space area per capita. Factors such as concentration of PM 2.5 had a negative impact on premature mortality of chronic non-communicable diseases, while factors such as garden and green space area per capita had a positive impact. Conclusions:Disease burden caused by chronic and non-communicable diseases, such as malignant tumor, exits in Anhui. Men in urban area are key population in the prevention and control of chronic and non-communicable diseases in the future.

Objective lo investigate the protective effect of dihydromyricetin(DHM)against exercise-induced muscle damage(EIMD)in mice and its potential mechanism. Methods Adult male C57BL/6J mice were randomly divided into control group(CG),exercise group(EG),and exercise+100 mg/kg weightd DHM(DHM)group.The intervention lasted for four weeks,during which the animals in the EG and DHM groups were subjected to exercise training for 1 h per day.The day after the training,a 90-min treadmill exercise(slope:0 and speed:18 m/min)was conducted in both EG and DHM groups.Samples of blood and gastrocnemius muscles were harvested from the three groups 24 h after the exercise,followed by the measurement of serum creatine kinase(CK)and lactate dehydrogenase(LDH)activities,total superoxide dismutase(T-SOD)activity,malondialdehyde(MDA),and skeletal muscle mitochondrial enzyme complex Ⅰ and Ⅱ activities.Histological changes in the skeletal muscle were observed by transmission electron microscopy,and the protein expressions of mitochondrial function-related pathways were detected by Western blotting. Results Skeletal muscle morphological changes and mitochondrial damage were alleviated in the DHM group compared to those in the EG.The activities of EIMD markers CK and LDH and the level of lipid peroxidation were notably repressed and the serum T-SOD activity was enhanced after DHM intervention.Western blotting demonstrated that the expressions of sirtuin type 3(SIRT3),estrogen-related receptor alpha,and peroxisome proliferator-activated receptor-gamma coactivator-1 alpha in the skeletal muscle of mice increased after the DHM intervention. Conclusion DHM can relieve EIMD in mice,possibly by promoting the recovery of the mitochondrial structure and function in the skeletal muscle of mice after high-intensity exercise via the activation of the SIRT3 signaling pathway.

Objective: To understand current status and related factors of breakfast among primary and secondary school students in Zhejiang Province, so as to provide a scientific basis for improving breakfast habits of primary and secondary school students. Methods: During May to November of 2023, 33 326 students from grade four to six of primary schools and grade one to two of secondary schools were selected from 90 counties and cities in Zhejiang Province by using the stratified cluster random sampling method. General information and breakfast consumption were collected by questionnaire. Multivariate Logistic regression was used to analyze the related factors of breakfast. Results: About 81.29% of the primary and secondary school students reported regular breakfast consumption. The rate of regular breakfast consumption was higher on the school days (92.23%) than on the weekends (85.17%), and higher in primary school students (85.83%) compared to secondary school students (74.71%), with statistically significant differences ( χ 2=827.42, 655.03, P <0.01). About 49.19% of primary and secondary school students had their breakfast within 10 minutes or less, and 83.30% of primary and secondary school students had 3-5 food groups for breakfast. The proportions of students who consumed cereals and potatoes, milk, and eggs were respectively 18.76%, 28.85%, 14.63%. About 22.84%, 28.00 %, 32.60% and 32.23% of the students had no meat, soybeans, vegetables and fruits in their breakfast. The results of multivariate Logistic regression analysis showed that girls, rural area, secondary school, place of living (dormitory, others), migrant parent (one or both outside the hometown), late bedtime (22:00-22:59, 23:00 and later) and late wake up time (9:00 and later) on the weekends were positively correlated with no having breakfast every day ( OR=1.22, 1.40, 1.46, 1.20, 1.20, 1.34, 1.36, 1.41 , 3.51, 2.32, P <0.05). The time of physical activity per day (30-<60, 60-<90, 90-120, >120 min), bedtime (21:00-21:59, 22:00-22:59) and wake up time (6:00-6:59, 7:00-7:59) on school days were negatively correlated with no having breakfast every day ( OR=0.75, 0.64, 0.67, 0.64, 0.77, 0.82, 0.75, 0.67, P <0.05). Conclusions There is a considerable number of primary and secondary school students with irregular breakfast consumption, which are related to multiple factors. Therefore, it is necessary to strengthen nutrition education and improve the behavior of breakfast for primary and secondary school students.

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.

italic>Candida albicans (C. albicans) stands as the primary opportunistic fungal pathogen responsible for fungal infections. The formation of biofilms constitutes a key virulence trait of C. albicans and a pivotal factor in drug resistance. Consequently, the development of antifungal drugs possessing biofilm inhibitory properties holds importance in the treatment of fungal infectious diseases. This study conducted in-depth research of the novel biofilm inhibitor named 1-(cyclopentylamino)-3-(4-(2,4,4-trimethylpentan-2-yl)phenoxy)propan-2-ol (IMB-H12). IMB-H12 showed good inhibitory activity on the formation of biofilms and a certain scavenging effect on mature biofilms. Preliminary research on the mechanism of action has found that IMB-H12 can inhibit the transformation from yeast to hyphal phase, inhibit the formation of mycelium, and reduce the adhesion activity and hydrophobicity of Candida albicans. IMB-H12 could also induce changes in the content of cell wall components, downregulate the expression of multiple genes related to adhesion and hyphal formation. Therefore, further research on this compound is expected to discover new lead compounds with antifungal activity.

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 screen and quantitatively analyze differential quality markers （Q-Marker） in Zingiber officinale mixed and triturated with Schisandra chinensis （ZMTS） before and after processing. METHODS HPLC fingerprints of before processing [Z. officinale complicated with S. chinensis （ZWS）] and after processing （ZMTS） （10 batches each） were established. The differences of Q-Markers before and after processing were screened by the chemical pattern recognition method and Q-Marker “five principles”， and the contents were determined. RESULTS A total of 14 common peaks were identified in the fingerprints of ZWS， 22 common peaks were identified in the fingerprints of ZMTS， and 8 components were identified. Differential Q-Marker were screened by chemical pattern recognition and Q-Marker “five principles”， i. e. 6-gingerol， schisandrol A schisandrol B， 8-gingerol， 10-gingerol， schisandrin A， schisandrin B， schizandrin C. The average contents of the 8 differential Q-Markers in ZMTS were 229.46， 244.48， 39.96， 44.12， 61.17， 47.82， 100.11 and 9.70 μg/g， respectively. The average contents of the 4 differential Q-Markers （6-gingerol， schisandrol A， schisandrol B， 8-gingerol） in ZWS were 112.58， 19.01， 26.74 and 5.98 μg/g， respectively. CONCLUSIONS In this study， the differential Q-Markers before and after ZMTS processing are screened. The contents of the Q-Markers in ZMTS after processing are higher than those before processing.

Objective To investigate the effect of plasma microRNA(miR)-93-5p on ovarian granulosa cell proliferation in patients with polycystic ovary syndrome(PCOS)and its possible mechanism.Methods A total of 120 PCOS patients of childbearing period who were treated at Jiaozuo People's Hospital from January 2022 to January 2023 were selected as the PCOS group,and 18 healthy women of childbearing period who were physically examined at the same hospital during the same period were selected as the control group.The age,body weight and height of the subjects in the two groups were recorded,and the body mass index(BMI)was calculated.Fasting venous blood was collected from the subjects during the follicular phase of the natural menstrual cycle or the progesterone-induced withdrawal bleeding phase,and serum levels of luteinizing hormone(LH),follicle-stimulating hormone(FSH),total testosterone(TT),anti-Mullerian hormone(AMH),aspartate aminotransferase(AST),alanine aminotransferase(ALT),fasting insulin(FINS),and fasting blood glucose(FBG)were measured by using the electrochemical method;and the homeostasis model assessment of insulin resistance(HOMA-IR)was calculated.Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression level of miR-93-5p in plasma of patients in the two groups.Human ovarian granulosa cells(KGN cells)in logarithmic growth phase were cultured in 6-well plates with 3 × 105 cells per well,and they were randomly divided into the miR-93-5p mimics group,LY294002+miR-93-5p group,AZD5363+miR-93-5p group,negative control(NC)group,and blank control group.The KGN cells in the miR-93-5p group were transfected with miR-93-5p mimics;the KGN cells in the LY294002+miR-93-5p group were transfected with miR-93-5p mimics and treated with 50 mmol·L-1 LY294002 one hour before transfection;the KGN cells in the AZD5363+miR-93-5p group were transfected with miR-93-5p mimics and treated with 50 μmol·L-1 AZD5363 one hour before transfection;the KGN cells in the NC group were transfected with the negative control plasmids;and the KGN cells in the blank control group were not treated at all.The expression of miR-93-5p in the KGN cells in each group was detected by qRT-PCR,and the proliferation of the KGN cells in each group was detected by cell counting kit-8.Results There was no significant differences in age,FSH,ALT,and AST levels of patients between the PCOS group and the blank control group(P＞0.05).The BMI,TT,AMH,LH,FINS,FBG,and HOMA-IR of patients in the PCOS group were significantly higher than those in the blank control group(P＜0.05).The relative expression of miR-93-5p in plasma of patients in the PCOS group was significantly higher than that in the blank control group(t=-5.549,P＜0.001).miR-93-5p was moderately positively correlated with TT,FINS and HOMA-IR(r=0.434,0.622,0.586;P＜0.001)and was mildly positively correlated with FBG and LH(r=0.398,0.398;P＜0.001).The receiver operating characteristic curve showed that the optimal cut-off value for plasma miR-93-5p in diagnosing PCOS was 1.380,the area under the curve was 0.906(95％confidence interval:0.839-0.973,P＜0.001),the sensitivity was 0.858,the specificity was 0.833,and the Youden index was 0.691.The relative expression of miR-93-5p in the KGN cells in the miR-93-5p mimics group,LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly higher than that in the blank control group and NC group(P＜0.05).After 24,48 and 72 hours of culture,the proliferation of the KGN cells in the miR-93-5p mimics group,LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly higher than that in the blank control group and the NC group(P＜0.05);the proliferation of the KGN cells in the LY294002+miR-93-5p group and AZD5363+miR-93-5p group was significantly lower than that in the miR-93-5p mimics group(P＜0.05).Conclusion miR-93-5p in plasma is overexpressed in PCOS patients,and it may be involved in the occurrence and development of PCOS by mediating the proliferation of ovarian granulosa cells through the phosphoinositide 3 kinase/protein kinase B signaling pathway.The miR-93-5p level in plasma has a certain diagnostic value for PCOS.
