Network pharmacology and molecular docking were employed to predict the mechanism of Zhizhu Decoction in regulating macrophage polarization to reduce adipose tissue inflammation in obese children, and animal experiments were then carried out to validate the prediction results. The active ingredients and targets of Zhizhu Decoction were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). The inflammation related targets in the adipose tissue of obese children were searched against GeneCards, OMIM, and DisGeNET, and a drug-disease-target network was established. STRING was used to construct a protein-protein interaction(PPI) network and screen for core targets. R language was used to carry out Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses. AutoDock was used for the molecular docking between core targets and active ingredients. 24 SPF grade 6-week C57B/6J male mice were adaptively fed for 1 week, and 8 mice were randomly selected as the blank group. The remaining 16 mice were fed with high-fat diet for 8 weeks to onstruct a high-fat diet induced mouse obesity model. After successful modeling, the 16 mice were randomly divided into model group and Zhizhu Decoction group, with 8 mice in each group. Zhizhu Decoction group was intervened by gavage for 14 days, once a day. Blank group and model group were given an equal amount of sterile double distilled water(ddH_2O) by gavage daily. After the last gavage, serum and inguinal adipose tissue were collected from mice for testing. The morphology of inguinal adipose tissue was observed by hematoxylin-eosin(HE) staining, the levels of inflammatory factors interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent assay(ELISA), and the protein expression of macrophage marker molecule nitric oxide synthase(iNOS) and epidermal growth factor like hormone receptor 1(F4/80) was detected by immunofluorescence staining. Network pharmacology predicted luteolin, naringenin, and nobiletin as the main active ingredients in Zhizhu Decoction and 15 core targets. KEGG pathway enrichment analysis revealed involvement in the key signaling pathway of nuclear factor κB(NF-κB). Molecular docking showed that the active ingredients of Zhizhu Decoction bound well to the core targets. Animal experiment showed that compared with the model group, Zhizhu Decoction reduced the distribution of inflammatory cytokines in the inguinal adipose tissue of mice, lowered the levels of TNF-α and IL-6 in the serum(P<0.05, P<0.01), and down-regulated the expression of iNOS and F4/80(P<0.05). The results showed that the active ingredients in Zhizhu Decoction, such as luteolin, naringenin, and nobiletin, inhibit the aggregation of macrophages in adipose tissue, downregulate their classic activated macrophage(M1) polarization, reduce the expression of inflammatory factors IL-6 and TNF-α, and thus improve adipose tissue inflammation in obese mice.

Objective Viral encephalitis is an infectious disease severely affecting human health.It is caused by a wide variety of viral pathogens,including herpes viruses,flaviviruses,enteroviruses,and other viruses.The laboratory diagnosis of viral encephalitis is a worldwide challenge.Recently,high-throughput sequencing technology has provided new tools for diagnosing central nervous system infections.Thus,In this study,we established a multipathogen detection platform for viral encephalitis based on amplicon sequencing. Methods We designed nine pairs of specific polymerase chain reaction(PCR)primers for the 12 viruses by reviewing the relevant literature.The detection ability of the primers was verified by software simulation and the detection of known positive samples.Amplicon sequencing was used to validate the samples,and consistency was compared with Sanger sequencing. Results The results showed that the target sequences of various pathogens were obtained at a coverage depth level greater than 20×,and the sequence lengths were consistent with the sizes of the predicted amplicons.The sequences were verified using the National Center for Biotechnology Information BLAST,and all results were consistent with the results of Sanger sequencing. Conclusion Amplicon-based high-throughput sequencing technology is feasible as a supplementary method for the pathogenic detection of viral encephalitis.It is also a useful tool for the high-volume screening of clinical samples.

Objective To investigate the effect of varying blood pressure stratification on renal function in the diabetic population.Methods A prospective cohort study was conducted,enrolling 9 489 diabetic patients from a total of 101 510 Kailuan Group employees who underwent health examinations between July 2006 and October 2007.The follow-up period was(8.6±4.0)years.Participants were categorized into four groups based on their baseline blood pressure levels:normal blood pressure(systolic blood pressure<120 mmHg and diastolic blood pressure<80 mmHg),elevated blood pressure(systolic blood pressure 120-130 mmHg and diastolic blood pressure<80 mmHg),stage 1 hypertension(systolic blood pressure 130-140 mmHg and/or diastolic blood pressure 80-90 mmHg),and stage 2 hypertension(systolic blood pressure≥140 mmHg and/or diastolic blood pressure≥90 mmHg).The incidence density of chronic kidney disease(CKD)was compared among these groups.A multivariate Cox proportional hazards regression model was employed to assess the effects of different blood pressure levels on renal function in diabetic patients,with the stability of the results confirmed using a multivariate time-dependent Cox proportional hazards model.Sensitivity analysis was conducted after excluding cases of cardiovascular disease(CVD)during follow-up,and cases using antihypertensive and antidiabetic medications at baseline.Results(1)At baseline,stage 1 hypertension patients demonstrated statistically significant higher differences with age and body mass index(BMI)compared to normal blood pressure group(P<0.05).(2)By the end of the follow-up,2 294 cases of CKD were identified,including 1 117 cases of estimated glomerular filtration rate(eGFR)decline and 1 575 cases of urinary protein.The incidences density of CKD,eGFR decline and urinary protein for stage 1 hypertension group were 39.4,16.3 and 25.5 per thousand person-years,respectively,all of which were statistically significant different from normal blood pressure group(log-rank test,P<0.01).(3)Multivariate Cox regression analysis revealed that,compared to the normal blood pressure group,stage 1 hypertension was associated with a 29%increased risk of CKD(HR=1.29,95%CI 1.09-1.52)and a 40%increased risk of eGFR decline(HR=1.40,95%CI 1.08-1.80)in diabetic individuals.Conclusion Stage 1 hypertension significantly increases the risk of CKD and eGFR decline in diabetic individuals,with a particularly notable effect on the risk of eGFR decline.

Objective To investigate the efficacy of rituximab combined with immunosuppressive pulse therapy for thyroid-associated ophthalmopathy(TAO)and analyze its influence on clinical activity score(CAS)and prognosis.Meth-ods A total of 136 patients(272 eyes)with TAO who were admitted to Huanggang Central Hospital from March 2020 to October 2022 were selected and divided into an observation group(68 patients)and a control group(68 patients)using a random number table method.Patients in the control group were given immunosuppressive pulse therapy,while patients in the observation group were given rituximab plus immunosuppressive pulse therapy.Both groups were treated for 4 courses(7 days per course).The clinical efficacy,eye signs,CAS score,thyroid conditions[thyrotropin receptor antibody(TRAb),thyroid peroxidase antibody(TPOAb),thyroid volume],T lymphocyte subsets,and adverse reactions were compared between the two groups.After a follow-up period of six months,the prognosis of patients in the two groups was compared.Results After 4 courses of treatment,the total effective rate of patients in the observation group was 94.12％(64/68),which was higher than that in the control group(82.35％,56/68)(P＜0.05).After 2 and 4 courses of treat-ment,the degree of exophthalmos,intraocular pressure,average palpebral fissure width,retrobulbar soft tissue volume,distance from the bulbus oculi,CAS score,TPOAb,TRAb,and thyroid volume of patients in the observation group were smaller than those in the control group,and all decreased compared to before treatment(all P＜0.05);the thickness of the tear film lipid layer was greater than that in the control group,and both increased compared to before treatment(all P＜0.05).There were no significant differences in the said indicators between the two groups before treatment(all P＞0.05).The CD3+,CD4+,and CD8+T lymphocyte levels of patients showed no significant difference between the two groups before treatment(all P＞0.05).After 2 and 4 courses of treatment,the levels of CD3+and CD4+T lymphocyte in both groups were higher than those before treatment.Except that the CD4+T lymphocyte level in the observation group was lower than that in the control group after 2 courses of treatment,the levels of CD3+and CD4+T lymphocyte in the obser-vation group were higher than those in the control group at other time points(all P＜0.05).After 2 and 4 courses of treat-ment,the level of CD8+T lymphocyte in both groups decreased compared to before treatment,and it was lower in the ob-servation group than the control group(all P＜0.05).There was no significant difference in the incidence of adverse reac-tions such as low fever,nausea,and hypokalemia between the two groups(all P＜0.05).After the 6-month follow-up,the improvement rate of patients in the observation group was 95.59％(65/68),which was higher than that in the control group(79.41％,54/68)(P＜0.05).Conclusion Rituximab combined with immunosuppressive pulse therapy is effec-tive for TAO.It can alleviate eye signs and thyroid conditions,reduce clinical activity,and promote prognosis.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

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.

This paper investigated the mechanism of Huoxue Dingxuan Capsules(HXDX) on autophagy in vascular endothelial cells based on the "crosstalk" of Bcl-2 and mTOR protein. bEnd.3 cells were divided into a blank control group, a model group, and an HXDX group. CO-IP experiments were conducted, and then Western blot(WB) was used to detect the binding of Bcl-2 and mTOR. Co-localization of Bcl-2 with mTOR protein was observed by laser confocal microscopy after staining. The model of Bcl-2 siRNA in bEnd.3 cells was constructed, and the bEnd.3 cells were divided into five groups, including blank control group, oxygen-glucose deprivation(OGD) group, transfected Bcl-2 siRNA group, negative control(NC) group, and HXDX group. The model of mTOR siRNA in bEnd.3 cells was constructed, and the bEnd.3 cells were divided into five groups, including blank control group, OGD group, transfected mTOR siRNA group, NC group, and HXDX group. The expression of autophagy-related proteins was detected by WB. The results of CO-IP experiments showed that Bcl-2 and mTOR proteins could be co-localized and expressed in bEnd.3 cells, and the expression of Bcl-2 and mTOR proteins increased after the intervention of the HXDX-containing serum. After screening and transfection with Bcl-2-mus-384, autophagy of bEnd.3 cells was induced. The expression of Bcl-2 in the Bcl-2 siRNA group was significantly decreased compared with the blank control group and model group. The expression of mTOR protein was significantly lower than that of the OGD group, and the expression of human microtubule-associated protein light chain 3Ⅱ/Ⅰ was significantly higher than that of the model group. After the intervention of the HXDX-containing serum, the expression of Bcl-2 and mTOR was increased in the HXDX group compared with that in the Bcl-2 siRNA group, and the expression of LC3Ⅱ/LC3Ⅰ and Beclin1 was decreased in the HXDX group compared with that in the Bcl-2 siRNA group. After transfecting mTOR-mus-7061 and inducing autophagy of bEnd.3 cells, in the mTOR siRNA group, mTOR protein expression was decreased compared with the blank control and model groups, and LC3Ⅱ/LC3Ⅰ and Beclin1 protein expression was increased compared with the model group. After the intervention of the HXDX-containing serum, the expression of Bcl-2 and mTOR was increased in the HXDX group compared with that in the mTOR siRNA group, and the expression of LC3Ⅱ/LC3Ⅰ and Beclin1 proteins was decreased compared with the mTOR siRNA group. This study explored the "crosstalk" of Bcl-2 and mTOR during autophagy in bEnd.3 cells at the cellular level and illustrated the modulating effect of the HXDX-containing serum, which provided a basis for the treatment of cervical spondylosis of vertebral artery type.
