ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）/cAMP-response element binding protein （CREB） signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet， intraperitoneal injection of isoproterenol （ISO）， and chronic unpredictable mild stress （CUMS）. A total of 108 SD male rats were randomly divided into normal group， model group， high （23.4 g·kg^-1）， medium （11.7 g·kg^-1）， and low （5.85 g·kg^-1） dose groups of modified Chaihu Shugansan， CaMKⅡ inhibitor （KN93） group， and KN93 + high， medium， and low dose groups of modified Chaihu Shugansan， with 12 rats in each group. From the first day of modeling to the end of modeling， drugs were administered once a day. In the seventh and eighth weeks， the KN93 group and the KN93 + high， medium， and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week， behavioral tests including sucrose preference， open field， and elevated plus maze were conducted. Electrocardiogram （ECG） lead Ⅱ changes were observed in each group of rats， and hematoxylin-eosin （HE） staining was performed to observe changes in heart tissue. Serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein （HDL）， low-density lipoprotein （LDL）， and lactate dehydrogenase （LDH） were measured by using an enzyme-labeled instrument. Creatine kinase （CK） and creatine kinase-MB （CK-MB） were detected by ultraviolet spectrophotometry， while serum monocyte chemoattractant protein-1 （MCP-1） was measured by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue， and Western blot was performed to assess protein expression of CaMKⅡ， phosphorylated （p）-CaMKⅡ， CREB， and p-CREB. ResultsCompared to the normal group， the model group showed significant reductions in sucrose preference rate， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）. The ECG showed ST-segment elevation， and HE staining showed serious degeneration of myocardial fibers， disordered arrangement， and infiltration of a large number of inflammatory cells. In addition， serum TC and LDL levels increased （P<0.01）， and HDL level decreased （P<0.01）. CK， CK-MB， LDH， and MCP-1 levels significantly increased （P<0.05， P<0.01）. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue （P<0.05， P<0.01）， but those increased in the heart tissue （P<0.01）. Compared to the model group， the high， medium， and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）， as well as decreased serum CK， CK-MB， LDH， and MCP-1 levels （P<0.05， P<0.01）. KN93 also reduced ST-segment elevation， alleviated the degeneration degree of myocardial fibrosis， and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced （P<0.05， P<0.01）. The KN93 + high， medium， and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression， possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway， with the high-dose modified Chaihu Shugansan showing the best effects.

Objective To understand the current status and influencing factors of patient perception for humanistic care in China hospitals,and to provide a basis for developing nursing humanistic care measures and improving the quality of nursing humanistic care services.Methods A total of 30,099 outpatients and inpatients from 107 hospitals in 30 provinces(autonomous regions and municipalities)from July to August 2022 as survey subjects.A general information questionnaire and the Relational Caring Questionnaire-Patient Form were used for a cross-sectional survey,and a single-factor analysis was used to analyze the influencing factors of patient relationship care.Results Finally,29 108 valid questionnaires were collected,and the effective questionnaire recovery rate was 96.7％.The patient evaluation of relationship care was(65.72±8.61)points.Single-factor analysis showed that gender,age,marital status,children's situation,education level,occupation,place of residence,average family income,medical insurance type,visiting department,and location of the visiting hospital,and whether or not surgery were influencing factors of patient relationship care(P＜0.05).Conclusion The evaluation score of caregiver-patient relationship care among Chinese hospital patients is above average,but there is still room for improvement in western and rural regions,seriously ill and outpatient patients,low-income and low-medical insurance reimbursement populations,and non-surgical patients.Medical institutions at all levels should optimize and improve nursing humanistic care services based on influencing factors,and further enhance patients'perception of nursing humanistic care.

[Objective]To explore the clinical characteristics of neurobrucellosis in Kashi,Xinjiang Uygur Autono-mous Region,thus improve the diagnosis and treatment.[Methods]A retrospective analysis was conducted on the clinical data of 18 cases of neurobrucellosis who were admitted to the First People's Hospital of Kashi Prefecture between Decem-ber 2019 and January 2024.[Results]The study included 9 males and 9 females,with a median age of 36 years(range:17-54.5).A clear epidemiological history was found in all the 18 brucllosis patients,12 of whom presented with meningo-encephalitis,5 meningitis,and 1 encephalitis.Two comorbided with spinal meningitis,2 osteoarthritis and 1 epididymitis.Most frequently reported clinical symptoms were headache,fever and fatigue.The prevalence rates of brucellosis by rose bengal plate agglutination test(RBPT)and serum agglutination test(SAT)were 11/12 and 8/9,respectively.Two of 10 patients had positive blood cultures,four of 16 had positive cerebrospinal fluid(CSF)cultures and five of five were detect-ed to be positive by next-generation sequencing(NGS)for pathogens in CSF.CSF showed exudative changes and elevated number of leukocytes,with predominance of single nucleated cells.All patients were treated with the combined use of two to four from the drugs like doxycycline,rifampicin,ceftriaxone,cefixime,minocycline,levofloxacin and sulfanilamide.Most patients had a favorable prognosis.[Conclusions]Neurobrucellosis should be considered in all patients with central nervous system manifestations from endemic areas.If there are exudative changes in CSF,differential diagnoses can be made by serological testing,blood culture,CSF culture and NGS.NGS could significantly increase the accuracy for neuro-brucellosis diagnosis.

Objective:To investigate syphilis infection and related factors among HIV-infected patients being followed up for more than one year in Zhejiang Province.Methods:Data were collected from the China Disease Control and Prevention Information System, and information such as demographic characteristics, viral load levels, and syphilis serologic test results was collected from HIV-infected persons who were diagnosed with HIV more than 1 year, aged ≥15 years with a current address in Zhejiang Province through December 31, 2022. The logistic regression model analyzed the prevalence of syphilis and the related factors. The SPSS 19.0 software was used for statistical analysis.Results:A total of 33 734 HIV-infected patients, with the prevalence of syphilis was 5.6% (1 879/33 734). Among the syphilis cases, the prevalence of syphilis was 6.4% (1 774/27 934) of males, 7.5% (640/8 543) of 25-34 years old age group, 7.6% (1 025/13 423) of unmarried, 8.3% (1 239/14 862) of homosexual transmission, 6.9% (214/3 080) with a non-local registered residence and 9.6% (602/6 267) with a history of STD before the HIV diagnosis. Multivariate Logistic regression analysis showed that participants who were male (a OR=2.19, 95% CI:1.77-2.72), 25-34 years old age group (a OR=1.80, 95% CI:1.47-2.20), homosexual transmission (a OR=1.67, 95% CI:1.49-1.88), with other provinces registered residence (a OR=1.26, 95% CI:1.09-1.47), and with a history of sexually transmitted disease (STD) before the HIV diagnosis (a OR=1.98, 95% CI:1.78-2.20) were associated with increased risk of syphilis. Being married (a OR=0.79, 95% CI:0.68-0.92) was associated with a decreased risk of syphilis. Conclusions:Syphilis infections were high in HIV-infected patients followed up more than one year in Zhejiang Province. It is recommended that syphilis surveillance and screening frequency should be strengthened among HIV-infected persons with characteristics such as male, homosexual transmission, and STD history.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

AIM:To determine the link between infliximab,adalimumab,vedolizumab,ustekinumab and risk of lymphoma in order to provide reference for the safety of clinical application.METHODS:Dis-proportionality analysis and Bayesian analysis were used in data mining to screen the suspected lym-phoma after the use of four biological agents based on the FAERS data from October 2012 to June 2023.The fatality and hospitalization rates of this four biological agents associated lymphoma were also investigated.RESULTS:Totally 705 cases of four biological agents associated lymphoma were collected.Four biological agents associated lymphoma appeared to influent more young pa-tients and middle-aged patients than elderly pa-tients(25.11％vs.22.41％vs.12.2％).There were slightly more male than females(42.84％vs.35.60％).Infliximab has the highest reporting odds ratio[ROR3.40,95％CI=(3.03,3.82)],proportional ratio[PRR3.38,95％CI=(3.01,3.79)],information component(IC1.14,IC-2SD=1.02)and empirical Bayes geometric mean(EBGM2.21,EBGM05=2.01).Significant difference in the fatality rate and hospi-talization rate among four biological agents were not found.CONCLUSION:Infliximab showed a strongest lymphoma association than the other three biological agents.Lymphoma risk should be vigilant when using infliximab.

Objective:To evaluate the medical service quality of psychiatric hospitals in Beijing based on diagnostic related group (DRG), analyze the evaluation effect, for refences to constructe a DRG performance evaluation system suitable for psychiatric hospitals.Methods:This study extracted data such as the number of DRG groups, etc. of hospitalized patients in 14 tertiary and secondary psychiatric hospitals in Beijing from 2018 to 2020 from the Beijing inpatient medical performance evaluation platform, and analyzed data on DRG performance evaluation indicators, as well as the average length of hospital stay and average cost of DRG enrolled cases. All data were analyzed using descriptive research methods, and inter group comparisons were conducted using the Mann Whitney U-test. Results:From 2018 to 2020, the average number of DRG groups in tertiary hospitals (28) was higher than that in secondary hospitals (10) ( P<0.05), and the average CMI values of both were the same(1.79); The average cost consumption index (1.15) of tertiary hospitals was higher than that of secondary hospitals (0.65) ( P<0.05), while the average time consumption index (1.11) was slightly lower than that of secondary hospitals (1.30); The mortality rate of the low-risk group in tertiary hospitals (0.01%) was generally lower than that in secondary hospitals (0.88%), and the average percentage of DRG admitted inpatients (82.8%) was significantly higher than that in secondary hospitals (27.3%) ( P>0.05). The average length of stay and cost per case for DRG enrolled inpatients in tertiary and secondary hospitals were lower than the overall hospital discharge cases ( P<0.05). Conclusions:The number of DRG groups, CMI value, and low-risk mortality rate could be used for evaluating the medical service capacity and safety of psychiatric hospitals, but the cost and time consumption index could not objectively reflect the efficiency of hospital medical services. DRG performance evaluation indicators are more suitable for evaluating short-term hospitalization of psychiatric patients. The proportion of DRG enrolled cases might be a potential indicator for evaluating the service quality of psychiatric hospitals.

Objective:To analyze the trends and related factors of HIV self-testing willingness in young students in Zhejiang Province, and provide evidence for the development of AIDS prevention and control measures in young students.Methods:From 2017 to 2021, HIV/AIDS sentinel surveillance was carried out in students of colleges and universities in all 11 cities of Zhejiang Province. One university or vocational and technical college in each city was selected as a sentinel school. An anonymous questionnaire survey was conducted among 800 students aged ≥16 years and selected by phased cluster sampling in each university or college from April to June in each year to collect information about their social demographic characteristics, sexual behavior, HIV prevention and test services acceptance. The HIV self-testing willingness and the influencing factors were analyzed.Results:A total of 45 483 students were surveyed from 2017 to 2021, and the proportions of those with willingness of HIV self-testing were 0.4% (35/9 107), 3.7% (334/9 150), 5.2% (475/9 203), 6.3% (563/8 962)and 7.4% (674/9 061) respectively (trend χ2=582.74, P< 0.001). Among young students who had sexual contact history, the multivariate logistic regression analysis showed that factors related with higher willingness of HIV self-testing included those majoring in medicine ( OR=1.57, 95% CI:1.06-2.33), seeking sexual partners through internet or social-dating application ( OR=1.96, 95% CI:1.33-2.89), receiving HIV prevention services in the last year ( OR=1.33, 95% CI:1.02-1.74), and being heard of vending machines selling HIV test kits ( OR=1.80, 95% CI:1.34-2.41). The factors related with lower willingness of HIV self-testing inclued those who had multiple heterosexual partners ( OR=0.57, 95% CI: 0.36-0.89). Conclusions:The willingness of HIV self-testing in young students increased in Zhejiang during 2017-2021, the young students who had sex were more willing to self-test among them but the level was still low. It is necessary to further strengthen the health education of HIV/AIDS prevention and control and provide better testing services to promote HIV self-testing.

Objective:To identify the transmission relationship between HIV infection cases the non-marital non-commercial heterosexual contact in Zhejiang Province.Methods:When HIV positive was informed during January 2020 to January 2022, the staff conducted an epidemiological investigation to collect cases information on sociodemographic characteristics, mobility information, past HIV testing history, high-risk sexual behaviors, sexual partners, and etcetera. At the same time, 6-8 ml of blood from the new diagnosis of people infected with HIV before antiviral treatment was collected to separate the bleeding plasma. pol gene was amplified by nucleic acid extraction and PCR, sequenced by Sequencer 5.0 software, and Cytoscape 3.6.0 software was used to draw HIV molecular transmission network. Results:From January 2020 to January 2022, 88 HIV infected individuals were found in Pujiang County, of which 74 were transmitted through heterosexual transmission, of which 31 were infected through non-marital non-commercial heterosexual contact. Preliminary case studies have found that three female cases have engaged in unprotected non-marital non-commercial heterosexual contact with one male case. Among the 4 infected individuals, 2 of their spouses tested positive for HIV antibodies. Molecular transmission network monitoring was carried out on 65 newly diagnosed cases of heterosexual transmission with acquired sequences, forming 9 transmission clusters. The largest cluster contained 10 cases. A total of 11 HIV-infected individuals were involved in this HIV cluster epidemic. They were 3 males and 8 females, all over 50 years old and were farmers or rural housewives. They were traced to 7 sexual partners (6 negatives of HIV, 1 undetected). Among the 18 respondents' sexual social network relationships, there were 6 couples, 8 permanent partners, and 3 temporary partners. Among 11 HIV infected individuals, there were 9 cases of non-marital non-commercial heterosexual transmission and 2 cases of intramarital transmission. The epidemiological association between 7 non-married non-commercial heterosexual partners and case 2 (56-year-old male farmer), 3 cases confirmed by epidemiological investigation and molecular transmission cluster results, 3 cases confirmed by molecular transmission cluster and epidemiological investigation results, and 1 case confirmed by epidemiological investigation results.Conclusions:The transmission mode of this cluster epidemic was to spread HIV through heterosexual sex with a male case as the core, then cause the transmission within marriage and between fixed sexual partners. The combination of epidemiological investigation and molecular transmission network traceability survey supports the conclusion of this study.

Objective:To investigate the prevalence of syphilis in HIV-infected patients with transmission risk and influencing factors in Zhejiang Province.Method:The information about the HIV-infected patients, who were alive, had been diagnosed with HIV for >1 year, had received no antiviral treatment or had HIV viral load ≥50 copies/ml, and were aged ≥15 years, reported in Zhejiang as of December 31, 2018 were collected from China Information System for Disease Control and Prevention. The information included general demographic characteristics, sexual behavior characteristics and antiretroviral therapy and syphilis serological test results. The prevalence of syphilis and the influencing factors were analyzed by logistic regression model. The SPSS 19.0 software was used for statistical analysis.Results:A total of 2 275 HIV-infected patients were at risk of HIV transmission, and 75.5% (1 717/2 275) of them were tested for syphilis, the prevalence rate of syphilis was 8.7% (150/1 717). Among the HIV-infected patients with syphilis, 11.3% (17/150) received no antiviral treatment, 38.7% (58/150) had viral load of 50-999 copies/ml and 50.0% (75/150) had ≥1 000 copies/ml. Multivariate logistic regression analysis showed that being men (a OR=2.04, 95% CI:1.06-3.96), homosexual transmission (a OR=1.53, 95% CI:1.04-2.27), history of sexually transmitted diseases (STDs) before HIV diagnosis (a OR=1.98, 95% CI:1.35-2.92) and HIV viral load ≥1 000 copies/ml (a OR=1.90, 95% CI:1.09-3.30) were the risk factors for syphilis. Marriage (a OR=0.47, 95% CI: 0.29-0.76) was a protective factor for syphilis. Conclusions:The prevalence of syphilis was high in HIV-infected patients with transmission risk in Zhejiang. It is urgent to carry out classified management and targeted intervention in HIV-infected patients, explore multi-disease prevention and treatment mechanism, strengthen syphilis screening and treatment in HIV-infected patients to reduce the transmission of HIV and syphilis.
