ObjectiveTo identify and analyze the possible influencing factors of obesity among public primary school students in Minhang District， Shanghai. MethodsBasic data， collected through questionnaire stars， was imported with merged physical examination data into Excel to form a database. Data were collected by questionnaire and analyzed by SPSS 22.00. Independent sample t-test was used for the data with normal distribution. Nonparametric test was used for the data with non-normal distribution. χ² test was used for the quantitative data. Logistic regression was used for univariate and multivariate analysis. ResultsAccording to the national physical health standards for students （revised in 2014） ， the prevalence rate of obesity among primary school students in Minhang district was 29.63% . The prevalence of overweight and obesity was 32.1% in boys and 26.9% in girls. The trend of overweight and obesity in different grades was similar among different genders .A single factor analysis showed that， being the only child （χ²=9.300， P<0.01） ， father obesity（χ²=106.417， P<0.001） or mother obesity（χ²=118.534， P<0.001） ， mother's overweight during pregnancy （χ²=159.731， P<0.001） ， caregiver's role as grandparents （χ²=38.736， P<0.001） ， low education level （χ²=111.309， P<0.001） had effects on overweight and obesity of children while the differences had statistical significance. Pupil's bad eating habit （χ²=18.905，P<0.001） and preference （χ²=22.901， P<0.001） ， insufficient sleep time （χ²=61.685， P<0.001） ， long-time using of electronic products （χ²=37.182， P<0.001） and low-time of exercise （χ²=15.328， P<0.001） also affected the obesity of primary school students. Among the five factors of family， diet， psychology， static state and dynamic state， the influencing factors of obesity in primary school students from grade one to grade four were being the only child， obese father and/or mother， overweight mother during pregnancy， caregivers without higher education. In terms of diet， it was mainly based on eating habits before bedtime， as well as partial and picky eating habits. In terms of psychology， the main psychological source was the pressure of learning in school. There was a clear relationship between the pace of learning and not keeping up. Static analysis revealed a correlation with lack of sleep. After assigning values based on eye hygiene recommendations for the use of electronic products， it was found that there was no direct correlation between obesity in primary school students and the duration of electronic product use. Dynamic analysis showed that not taking part in school physical exercise was related to obesity. ConclusionThe obesity of primary school students is influenced by family， diet， psychology， static and dynamic factors. The intervention of obesity in primary school needs the joint efforts of school， society， family， self-cognition and so on.

OBJECTIVE To investigate the efficacy and safety of piperacillin-tazobactam in the treatment of complicated urinary tract infection （cUTI） in adults. METHODS Retrospective analysis was performed on the data of 352 cUTI adult patients in our hospital from January 1， 2021 to December 31， 2023. All patients received piperacillin-tazobactam. The detection of pathogens in patients， the clinical efficacy and microbial clearance rate after treatment， the occurrence of adverse drug reactions and treatment cost were observed in all patients. RESULTS Of the 352 patients， pathogen culture results of 54 patients were detected， mainly Escherichia coli producing extended-spectrum beta-lactamases. The clinical effective rate was 94.3%， the microbial clearance rate was 81.5%， and the incidence of adverse reactions was 1.4%. The percentage of male effective patients in urinary surgery department was significantly higher than invalid patients， while the proportion of transplant treatment and the proportion of patients with concomitant kidney transplantation were significantly lower than invalid patients （P＜0.05）. There was no significant difference in clinical effective rate between the two groups after those patients were divided into target treatment group and empirical treatment group according to the sensitivity of pathogen to piperacillin-tazobactam （P＝0.902 5）. CONCLUSIONS Piperacillin-tazobactam is effective and safe in the treatment of cUTI.

Objective To study the common basis and association between sickness behaviour and occurrence of classical symptoms of kidney yang deficiency of rats with adriamycin nephropathy.Methods The SD rats were given adriamycin by tail-vein injection for 2 times(4.0 and 3.5 mg·kg-1,one week apart)to construct the model of nephrotic syndrome with Chinese medicine symptom of kidney yang deficiency.After successful modeling,the model rats were randomly divided into adriamycin group(ADR group),corticosterone group(CORT group)and hydrocortisone group(HYD group),with 12 rats per group;another 12 normal rats were taken as normal group.In the HYD group,25 mg·kg-1·d-1 HYD was administered for 14 d to establish kidney yang deficiency model with simple hypothalamus-pituitary-adrenal cortex(HPA)axis inhibition.CORT group was adding 25 μg·mL-1 corticosterone to the water for 6 weeks,and the others drinking water supplied.The levels of urinary 17-hydroxy steroid were measured by enzyme linked immunosorbent assay.Glucocorticoid receptor(GR)and nuclear factor-kappa B(NF-κB)protein expression levels in kidney and hypothalamus were detected by Western blotting.Results In the normal,ADR,CORT and HYD groups,the urinary 17-hydroxysteroid levels were(19.14±1.94),(10.07±1.62),(20.30±1.55)and(14.23±2.37)μg·L-1;the relative expression levels of GR protein in hypothalamic were 0.63±0.05,0.11±0.05,0.85±0.08 and 0.35±0.06;the relative expression levels of NF-κB protein in hypothalamic were 0.06±0.03,0.96±0.03,0.59±0.01 and 0.23±0.04;the relative expression levels of GR protein in kidney tissue were 0.94±0.06,0.06±0.02,0.40±0.02 and 0.09±0.08;the relative expression levels of NF-κB protein in kidney tissue were 0.07±0.05,0.81±0.12,0.72±0.07 and 0.49±0.08,respectively.Compared with the ADR and HYD groups,the above indexes in the normal group were statistically significant(P＜0.05,P＜0.01).And compared with the ADR group,the relative expression levels of NF-κB protein in renal tissue with CORT group were not statistically significant(P＞0.05),but the other indexes in CORT group were statistically significant(all P＜0.01).Conclusion HPA axis dysfunction with GR damaged and activated inflammatory levels are the common basis for the combination of typical symptoms of kidney yang deficiency and sickness behaviour which characterised by"deficiency and cold syndrome".

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective China is among the 30 countries with a high burden of tuberculosis(TB)worldwide,and TB remains a public health concern.Kashgar Prefecture in the southern Xinjiang Autonomous Region is considered as one of the highest TB burden regions in China.However,molecular epidemiological studies of Kashgar are lacking. Methods A population-based retrospective study was conducted using whole-genome sequencing(WGS)to determine the characteristics of drug resistance and the transmission patterns. Results A total of 1,668 isolates collected in 2020 were classified into lineages 2(46.0%),3(27.5%),and 4(26.5%).The drug resistance rates revealed by WGS showed that the top three drugs in terms of the resistance rate were isoniazid(7.4%,124/1,668),streptomycin(6.0%,100/1,668),and rifampicin(3.3%,55/1,668).The rate of rifampicin resistance was 1.8%(23/1,290)in the new cases and 9.4%(32/340)in the previously treated cases.Known resistance mutations were detected more frequently in lineage 2 strains than in lineage 3 or 4 strains,respectively:18.6%vs.8.7 or 9%,P<0.001.The estimated proportion of recent transmissions was 25.9%(432/1,668).Multivariate logistic analyses indicated that sex,age,occupation,lineage,and drug resistance were the risk factors for recent transmission.Despite the low rate of drug resistance,drug-resistant strains had a higher risk of recent transmission than the susceptible strains(adjusted odds ratio,1.414;95%CI,1.023-1.954;P = 0.036).Among all patients with drug-resistant tuberculosis(DR-TB),78.4%(171/218)were attributed to the transmission of DR-TB strains. Conclusion Our results suggest that drug-resistant strains are more transmissible than susceptible strains and that transmission is the major driving force of the current DR-TB epidemic in Kashgar.

OBJECTIVE To assess the profiles of elements in benzo[a]pyrene(BaP)induced carci-nogenesis,and explore the joint effects of copper with cisplatin or vinorelbine on cell proliferation.METHODS Forty-four elements were measured using an inductively coupled plasma mass spectrometer in 16HBE cells and BaP malignantly transformed 16HBE(T-16HBE-C1)cells.Partial least square was used to validate the robustness of cell classification of elements.Cell viability was measured by MTT assay for copper(0,237,340,487,1000 and 1432 μmol·L-1),cisplatin(0,4.4,6.1,8.6,12.0 and 16.8 μmol·L-1),and vinorelbine(0,3.8,9.8,25.0,40.0 and 64.0 μmol·L-1)to acquire their half maximal inhibitory concentra-tion(IC50).Mixtures of copper and chemotherapeutics were prepared according to the ratio of each IC50.Their joint effects on cell viability were assessed by MTT assay and isobolographic analysis.Inhibition effect of copper(0,50,100,200,400 and 800 μmol·L-1)with IC50 of cisplatin or vinorelbine on prolifera-tion of T-16HBE-C1 cells was also assessed.RESULTS A total of 29 elements were quantified in 16HBE and T-16HBE-C1 cells,among which concentrations of copper,zinc,silver,selenium and rubidium decreased(P<0.05,P<0.01),while those of molybdenum,arsenic,lithium,germanium,strontium,nickel,lanthanum,mercury,iron,and cesium increased(P<0.05,P<0.01)in T-16HBE-C1 cells.Element concen-tration could be used to distinguish T-16HBE-C1 cells from 16HBE cells.Copper concentration-dependently inhibited proliferation of both cells,with a statistically significant lower IC50 of(613±16)μmol·L-1 in 16HBE cells than(776±15)μmol·L-1 in T-16HBE-C1 cells(P<0.01).Mixtures of copper and cisplatin(1∶69.5)or vinorelbine(1∶33.4)could inhibit cell proliferation,and copper had additive effects with cisplatin or vinorelbine.When copper concentration was higher than 400 μmol·L-1,copper combined with IC50 of cisplatin or vinorelbine inhibited cell proliferation of T-16HBE-C1 cells compared with IC50 of cisplatin(11.2 μmol·L-1)or vinorelbine(23.2 μmol·L-1)alone.CONCLUSION Element profiles and correlations can change significantly after 16HBE cells are malignantly transformed by BaP.Copper could inhibit the proliferation of T-16HBE-C1 cells and have additive effects with cisplatin or vinorelbine in higher concentration.

Objective:To investigate the effects of Ziyin Liangxue formula combined with prednisone on immune function and the ST2/IL-33 pathway in mice with immune thrombocytopenia.Methods:In 40 BALB/c mice,32 were constructed as immune thrombocytopenia mouse models by antiplatelet serum injection.After successful modeling,the mice were randomly divided into model group,Ziyin Liangxue formula group(0.2 ml/10 g),prednisone group(0.2 ml/10 g),and Ziyin Liangxue formula+prednisone group(0.2 ml/10 g),8 mice in each group,and the other 8 mice were set as control group.The drugs were administered by gavage at the dose,and the model group and control group were given equal amounts of saline by gavage once a day for 2 weeks of continuous intervention.Blood samples and spleen tissues were collected,the peripheral platelet count was measured by automatic hematology analyzer,the pathological changes in spleen tissue was observed by HE staining,the levels of serum transforming growth factor(TGF)-β,interleukin(IL)-17,and peripheral blood thrombopoietin(TPO)were detected by enzyme-linked immunosorbent assay(ELISA),the expression of IL-33,sST2,and ST2 in spleen tissue was detected by Western blot,and the cell counts of peripheral blood Th17 and Treg were detected by flow cytometry.Results:Compared with the control group,the number of platelets,the level of TPO,TGF-β,and Treg cells were significantly decreased(P＜().05),while the level of IL-17,Thl7 cells,and the expression of IL-33,sST2,and ST2 protein were significantly increased in the model group(P＜0.01).Compared with the model group,the number of platelets,the level of TPO,TGF-β,and Treg cells were significantly increased(P＜0.05),while the level of IL-17,Th17 cells,and the expression of IL-33,sST2,and ST2 protein were significantly decreased in the Ziyin Liangxue formula+prednisone group(P＜0.01).Conclusion:Ziyin Liangxue formula+prednisone can effectively regulate Th17/Treg balance,thus effectively improve immune thrombocytopenia,and the mechanism may be related to the regulation of ST2/IL-33 signaling pathway.

Purpose::Cerebral edema (CE) is the main secondary injury following traumatic brain injury (TBI) caused by road traffic accidents (RTAs). It is challenging to be predicted timely. In this study, we aimed to develop a prediction model for CE by identifying its risk factors and comparing the timing of edema occurrence in TBI patients with varying levels of injuries.Methods::This case-control study included 218 patients with TBI caused by RTAs. The cohort was divided into CE and non-CE groups, according to CT results within 7 days. Demographic data, imaging data, and clinical data were collected and analyzed. Quantitative variables that follow normal distribution were presented as mean ± standard deviation, those that do not follow normal distribution were presented as median (Q 1, Q 3). Categorical variables were expressed as percentages. The Chi-square test and logistic regression analysis were used to identify risk factors for CE. Logistic curve fitting was performed to predict the time to secondary CE in TBI patients with different levels of injuries. The efficacy of the model was evaluated using the receiver operator characteristic curve. Results::According to the study, almost half (47.3%) of the patients were found to have CE. The risk factors associated with CE were bilateral frontal lobe contusion, unilateral frontal lobe contusion, cerebral contusion, subarachnoid hemorrhage, and abbreviated injury scale (AIS). The odds ratio values for these factors were 7.27 (95% confidence interval ( CI): 2.08 -25.42, p = 0.002), 2.85 (95% CI: 1.11 -7.31, p = 0.030), 2.62 (95% CI: 1.12 -6.13, p = 0.027), 2.44 (95% CI: 1.25 -4.76, p = 0.009), and 1.5 (95% CI: 1.10 -2.04, p = 0.009), respectively. We also observed that patients with mild/moderate TBI (AIS ≤ 3) had a 50% probability of developing CE 19.7 h after injury (χ 2= 13.82, adjusted R2 = 0.51), while patients with severe TBI (AIS > 3) developed CE after 12.5 h (χ 2= 18.48, adjusted R2 = 0.54). Finally, we conducted a receiver operator characteristic curve analysis of CE time, which showed an area under the curve of 0.744 and 0.672 for severe and mild/moderate TBI, respectively. Conclusion::Our study found that the onset of CE in individuals with TBI resulting from RTAs was correlated with the severity of the injury. Specifically, those with more severe injuries experienced an earlier onset of CE. These findings suggest that there is a critical time window for clinical intervention in cases of CE secondary to TBI.

Oral solid dosage(OSD) occupies a key position in the market of Chinese patent medicines and new traditional Chinese medicines. Processing route is the foundation for the research and development of traditional Chinese medicine OSDs. On the basis of prescriptions and preparation methods of 1 308 traditional Chinese medicine OSDs recorded in the Chinese Pharmacopoeia, we summarized the patterns of processing routes of both modern dosage forms(tablets, granules, and capsules) and traditional dosage forms(pills and powder) and constructed a manufacturing classification system(MCS) based on the processing routes. Based on the MCS, statistical analyses were conducted respectively on medicinal materials, pharmaceutical excipients, extraction solvents in the pretreatment process, crushed medicinal materials, methods of concentration and purification, and methods of drying and granulation, aiming to uncover the process features. The results showed that each dosage form can be prepared via different routes with different processing methods of decoction pieces and raw materials for dosage preparation. The raw materials for dosage form preparation of traditional Chinese medicine OSDs included total extract, semi-extract, and total crushed powder, which accounted for different proportions. The raw materials for traditional dosage forms are mainly decoction pieces powder. Semi-extracts are the main raw materials for tablets and capsules, which account for 64.8% and 56.3%, respectively. Total extracts are the main raw materials for granules, with a proportion of 77.8%. Compared with tablets and capsules, traditional Chinese medicine granules with dissolubility requirements had a larger proportion of water extraction process, a higher proportion of refining process(34.7%), and a lower proportion of crushed medicinal mate-rials in semi-extract granules. There are four ways to add volatile oil to the modern dosage forms of traditional Chinese medicine. In addition, some new technologies and processes have been used in concentration, filtration, and granulation processes of traditional Chinese medicine OSDs, and the application of pharmaceutical excipients is diversified. The results of this study are expected to provide reference for the processing route design and upgrading of OSDs for new traditional Chinese medicines.
