Objective: To evaluate the current situation of thermal environment in primary and secondary school classrooms during winter, and to analyze students thermal comfort needs, so as to provide a basis for improving classroom thermal environment. Methods: From December 16 to 26, 2024, a stratified cluster random sampling method was used to select 90 classrooms from 15 primary and secondary schools in centralized/air conditioned heating areas(Liaoning Province, Tianjin City, Shanghai City) and naturally ventilated areas(Anhui Province and Jiangxi Province)for on site environmental measurement. A questionnaire survey was conducted among 743 students. The differences between groups using the χ 2 test were compared. Based on actual measurement data, a predicted mean vote prepared percentage of dissatisfied (PMV-PPD) model for centralized/air conditioned classrooms and an adaptive model for naturally ventilated classrooms were established, and the thermal neutral temperature and comfort interval were calculated. Results: The average outdoor temperature during on site measurement was 4.00(0.20，7.00)℃. In classrooms with centralized or air conditioned heating systems, the measured average temperature was (19.33±2.59)℃, with a thermal comfort range of 20.35-25.35 ℃ and a thermal neutral temperature of 22.85 ℃. And 13.92% of students reported feeling cold, while 80.80% felt comfortable. In classrooms with natural ventilation, the measured average temperature was (12.26±1.83)℃, with a thermal neutral temperature of 19.67 ℃ and a thermal comfort range of 16.17-23.17 ℃. About 48.33% of students reported feeling cold, and 49.81 % felt comfortable.The results of univariate analysis showed that there were statistically significant differences in shoe thickness, temperature sensation, relative humidity sensation and wind speed sensation between centralized/air conditioned heating areas ( χ 2= 7.01 , 31.47, 13.57, 13.80,all P <0.05). There were also statistically significant differences in school stage for primary and secondary school students, body mass index, classroom location for seat, temperature sensation, relative humidity sensation and wind speed sensation between naturally ventilated areas ( χ 2=42.13, 11.13, 11.04, 60.39, 29.27, 38.46,all P <0.05). Conclusions There are differences in thermal environment and students subjective thermal comfort in primary and secondary schools under different ventilation modes in winter. The temperature standards for heated classrooms should be revised, and differentiated environmental regulation strategies should be adopted based on different ventilation methods to improve students health and comfort levels.

Objective To compare the effects of upper limb remote ischemic preconditioning(RIPC)with different pressure modes on enhancing high-altitude acclimatization in healthy adult males rapidly exposed to high-altitude environments.Methods In May 2024,86 male adult residents living plain areas planning a high-altitude travel were recruited through advertisements in Chongqing by Department of Anesthesiology at the Second Affiliated Hospital of Army Medical University.The participants were randomly divided into a variable pressure training group(n=29),a constant pressure training group(n=29),and a control group(n=28).The variable pressure training group underwent RIPC training in a variable pressure mode[occlusion pressure was set at systolic blood pressure(SBP)+40 mmHg],while the constant pressure training group received RIPC training in a constant pressure mode(fixed occlusion pressure of 200 mmHg).Both groups completed a bilateral upper limb RIPC training(twice daily,5 cycles per time of 10-min occlusion followed by 5-min reperfusion)for 14 d.The control group received no such training.On the 3rd day post-training,all participants entered a simulated 4 500 m altitude chamber for 7 h.The incidence and severity of acute mountain sickness(AMS)were observed and evaluated,and the vital signs and cerebral tissue oxygenation index(CTOI)were recorded.Results The incidence of AMS was 23.1%in the variable pressure training group(RR=0.4,95%CI:0.2～0.8,Chi-square=9.433,P=0.002)and 16.0%in the constant pressure training group(RR=0.2,95%CI:0.1～0.6,Chi-square=12.833,P<0.001),and both incidences were significantly lower than that in the control group(65.4%).The AMS symptom score in the variable pressure training group[1.5(0.8,3.0)vs(3.1±1.9),P=0.018]and the score in the constant pressure training group[1.0(1.0,2.0)vs(3.1±1.9),P=0.001]were significantly lower than that in the control group.The dizziness score was obviously lower in the variable pressure training group[0(0,1.0)vs 1.0(1.0,1.0),P=0.001]and the constant pressure training group[1.0(0,1.0)vs 1.0(1.0,1.0),P=0.003]than the control group,so was the fatigue/weakness score in the variable pressure training group[0(0,0.3)vs 1.0(0,1.0),P=0.006],the constant pressure training group[0 vs 1.0(0,1.0),P<0.001],and the control group.The change of CTOI(ΔCTOI)in the variable pressure training group(P=0.010)and the constant pressure training group(P=0.042)was significantly lower than that in the control group.There were no statistical differences in the 3 groups in terms of SpO2,HR,SBP or DBP(P>0.05).What's more,no significant differences were observed in the incidence of AMS,AMS score,dizziness score,fatigue/weakness score,or ΔCTOI between the variable pressure training group and the constant pressure training group(P>0.05).Conclusion Both upper limb RIPC protocols,variable-pressure(SBP+40 mmHg)and fixed-pressure(200 mmHg),can effectively enhance high-altitude acclimatization by reducing AMS incidence,symptom severity,and cerebral oxygen desaturation.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Objective:To investigate the effects of Shengmai Decoction on postoperative recovery and the anxiety and depression in breast cancer patients after surgery.Methods:A prospective randomized controlled study was conducted. A total of 60 patients with breast cancer after operation in Dongzhimen Hospital, Beijing University of Chinese Medicine from October 2023 to July 2024 were selected, and all patients were divided into the Shengmai Decoction group and the control group according to the random number table method with 30 cases in each group. The Shengmai Decoction group was given the Shengmai Decoction 3 times per day (10 ml each time before meals) with continuous treatment for 7 d, and the patients in the control group drank 10 ml of water at the same time point. The scores of 40-item quality of recovery (QoR-40), traditional Chinese medicine syndrome, Pittsburgh sleep quality index (PSQI), self-rating anxiety scale (SAS), self-rating depression scale (SDS) before treatment and 7 d after treatment were compared and adverse reactions of the 2 groups were recorded.Results:All patients were female. In the Shengmai Decoction group, 17 patients (56.7%) underwent modified radical mastectomy and 13 patients (43.3%) underwent breast-conserving surgery with the age of (48±12) years; in the control group, 16 patients (53.3%) underwent modified radical mastectomy and 14 patients (46.7%) underwent breast-conserving surgery with the age of (51±12) years. There were no statistically significant differences in age, body mass index, surgery type, menopause, operation time, intraoperative blood loss and between the 2 groups (all P > 0.05). The difference in QoR-40 score before treatment between the 2 groups was not statistically significant ( P > 0.05). The emotional state score [(41.0±1.8) points vs. (38.0±2.7) points], psychological support score [(32.6±1.4) points vs. (30.3±1.5) points], and total score [(178.7±3.4) points vs. (170.1±3.9) points] of QoR-40 score in the Shengmai Decoction group were higher than those in the control group 7 d after treatment, and the differences were statistically significant ( t value was 5.21, 6.01, 9.04, all P < 0.05). The differences in the scores of traditional Chinese medicine syndrome, PSQI, SAS and SDS of both groups before treatment were not statistically significant (all P > 0.05). The scores of traditional Chinese medicine syndrome, PSQI, SAS and SDS of both groups 7 d after treatment were decreased compared with those before treatment, and the scores in the Shengmai Decoction group were lower than those in the control group, and the differences were statistically significant (all P < 0.05). The incidence of adverse reactions was 15.0% (2/30) and 10.0% (3/30) in the Shengmai Decoction group and the control group, respectively, and the difference was not statistically significant ( P > 0.05). Conclusions:Shengmai Decoction can enhance the postoperative sleep quality, improve anxiety and depression as well as the quality of postoperative recovery in patients with breast cancer.

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.

ObjectiveTo evaluate the effect of antihypertensive and lipid-regulating Chinese patent medicine combined with conventional Western medicine in the treatment of hypertension with dyslipidemia. To carry out the evidence synthesis of clinical research and provide evidence-based evidence support for clinical decision-making. MethodThe databases including China National Knowledge Infrastructure （CNKI），Wanfang Data Knowledge Service Platform （WF），VIP，SinoMed，Embase，PubMed，Web of Science （WOS），and the Cochrane Library were searched for randomized controlled trials （RCT） of all listed Chinese patent medicines in the treatment of hypertension with dyslipidemia from the establishment of the databases to April 15，2023. The literature was screened and extracted，and the risk of bias tool 2.0 （RoB2） was used to assess the quality and risk of bias of the methodology. Revman 5.4.1 software was used to analyze the outcome indicators. Grading of Recommendations Assessment，Development and Evaluation （GRADE） was applied to assess the quality of evidence formed by clinical research data. The inclusion and recommendation of Chinese patent medicines in the National Drug Catalogue for Basic Medical Insurance，Work-related Injury Insurance and Maternity Insurance （2022） and domestic guidelines and consensus were searched to form a bubble chart. ResultA total of 15 studies were included. The evaluation of the methodological quality of each study showed that the risk of bias stemmed from the lack of blinding and allocation concealment，and low sample size. The comprehensive analysis of clinical studies showed that Dengzhan Shengmai capsules combined with rosuvastatin and amlodipine besylate，Yindan Xinnaotong capsules combined with simvastatin and levamlodipine tablets，Xiaoshuan Tongluo capsules combined with nifedipine controlled release tablets and pravastatin sodium tablets，Xinshubao capsules combined with atorvastatin calcium tablets and irbesartan，Wenyading capsules combined with enalapril，and Jiangzhining tablets combined with conventional Western medicines were all superior to conventional Western medicines used in the control group in improving systolic blood pressure （SBP），diastolic blood pressure （DBP），cholesterol （TC），triglyceride （TG），low density lipoprotein cholesterol （LDL-C），and high density lipoprotein cholesterol （HDL-C）. There was no significant difference in the incidence of adverse reactions between the two groups. The GRADE evaluation of the main outcome indicators showed that the evidence quality of SBP and incidence of adverse reactions was graded as B，that of DBP as C，and that of total TC，TG，LDL-C，and HDL-C as D. The evaluation of Chinese patent medicines covered by medical insurance and recommended by guidelines and consensus showed that Yindan Xinnaotong soft capsules，Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules belonged to class B drugs of medical insurance，and were recommended for 7，6 and 3 times in the guidelines and consensus，respectively. ConclusionCompared with simple medicine treatment，Chinese patent medicine combined with conventional Western medicine has more advantages in improving blood pressure and blood lipid，and shows higher safety. Among them，Yindan Xinnaotong soft capsules，Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules have stronger clinical applicability and economy. All the trials included in this article adhered to the principle of randomization and reported the outcome measures. However，the quality of evidence in related clinical studies was low. In terms of trial design，large-sample，multi-center，blinded randomized controlled trials based on the consolidated standards of reporting trials （CONSORT） statement are still needed for comprehensive trial designs and reporting，to further improve the GRADE quality evaluation and guideline formulation under the guidance of evidence-based medicine，so as to provide higher quality evidence-based research evidence for clinical decision-making.

ObjectiveTo evaluate the quality of research and evidence related to antihypertensive Chinese patent medicines combined with western medicines for the treatment of hypertension， synthesize and update the evidence， form expert consensus， and provide evidence for clinical decision-making. MethodThe databases of China National Knowledge Infrastructure （CNKI）， WanFang Data Knowledge Service Platform （WanFang）， Vip Chinese Science and Technology Journal Database （VIP）， Chinese Biomedical Literature Service System （Sinomed）， National Library of Medicine （PubMed）， Cochrane Library， Web of Science， and US Clinical Trials Registry were searched for randomized controlled trials of antihypertensive Chinese medicine combined with western medicine for the treatment of hypertension from database construction to July 31， 2022. The quality of the literature was evaluated using the bias risk assessment tool in Cochrane Handbook 6.3. Evidence synthesis of main outcome indicators was performed using R software. The Grading of Recommendations Assessment， Development， and Evaluation profiler （GRADEprofiler） 3.6 was employed to evaluate the quality of evidence. Expert consensus was formed based on the Delphi method after two rounds of voting. Result64 pieces of literature were included， and the results of literature quality evaluation and risk of bias showed that 70.31% （45/64） of the studies indicated some risks， and 29.69% （19/64） indicated high risks. Compared with conventional western medicines， the combination of Chinese patent medicines with western medicines can significantly lower systolic pressure （SBP） and diastolic pressure （DBP）， increase the effective rate of antihypertensive， reduce the incidence of adverse reactions， endothelin-1， and traditional Chinese medicine syndrome scores. Egger's test showed that Songling Xuemaikang capsules reduced SBP and DBP. Tianma Gouteng granules reduced SBP and DBP and increased the effective rate of antihypertensive， and Xinmaitong capsules reduced SBP and increased the effective rate of antihypertensive， without significant publication bias. Songling Xuemaikang capsules increased the effective rate of antihypertensive， and Xinmaitong capsules decreased DBP， with significant publication bias. The results of the GRADE evidence quality evaluation showed that most evidence was at grades B and C. Finally， four strong recommendations and 14 weak recommendations were formed. ConclusionCompared with conventional western medicines for the treatment of hypertension， antihypertensive Chinese patent medicines combined with western medicines have advantages in reducing blood pressure and improving drug use safety， but they are mostly weak recommendations in terms of efficacy， and more high-quality evidence is needed.

ObjectiveTo systematically collect， analyze， and evaluate the randomized controlled trials （RCT） of Chinese patent medicine combined with western medicine in the treatment of hypertension， map the evidence， and provide reference for the future clinical research and formulation of guidelines and policies. MethodThe relevant articles were retrieved from China Biology Medicine disc， China National Knowledge Infrastructure （CNKI）， VIP， Wanfang Data， PubMed， Embase， and Cochrane Library with the time interval from inception to December 31， 2022. The RCT of Chinese patent medicines combined with western medicine in the treatment of hypertension were included. The research characteristics and methodological quality were analyzed and evaluated. ResultA total of 330 RCTs of treating hypertension with Chinese patent medicines combined with Western medicine were included in this study， all of which were published in Chinese. These RCTs involved 88 Chinese patent medicines and 37 788 patients， and 46% of RCT had the sample size ≥100 patients. Eighty-seven percent of RCT showed the study period within 3 months. All the interventions in the RCTs were Chinese patent medicine + western medicine vs western medicine. Among the evaluation indicators， blood pressure， response rate， TCM syndrome score， endothelial cell function， and safety were mainly concerned. In terms of methodological quality， most articles did not mention the generation of random sequences， allocation concealment， or blinding method. The blinding evaluation of outcomes showed low risks of bias， and there was insufficient information to judge whether there was selective bias or other bias. ConclusionThere were many Chinese patent medicines used in combination with western medicine in the treatment of hypertension， and they were mainly taken orally. The existing RCT had problems such as small sample size， unclear clinical value positioning， imperfect design failing to reflect the value of Chinese patent medicines， unreasonable measurement indicators， and non-standard measurement methods. Future research should solve the above problems， improve the research quality， value， and authenticity， and enhance the reliability and extension of evidence.
