ObjectiveTo explore the clinical efficacy and safety of Da Chaihutang （DCH） for the treatment of sepsis with Yang syndrome. MethodsA total of 70 patients suffering from sepsis with Yang syndrome were randomly divided into an observation group and a control group， with 35 cases in each group. They both received standard Western medicine treatment. The observation group was additionally given a dose of DCH， which was boiled into 100 mL and taken twice. The control group was additionally given an equal volume and dosage of warm water. The intervention lasted for three days. The 28-day all-cause mortality and the changes in the following indicators before and after intervention were compared between the two groups， including sequential organ failure assessment （SOFA）， acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ） score，white blood cell （WBC），the percentage of neutrophils （NEU%），C-reactive protein （CRP），procalcitonin （PCT），alanine transaminase （ALT），aspartate transaminase （AST），total bilirubin （TBil），creatinine （Cr），blood urea nitrogen （BUN），acute gastrointestinal injury （AGI） grade，gastrointestinal dysfunction score （GDS），serum intestinal fatty acid-binding protein （iFABP）， citrulline （CR），platelet （PLT），prothrombin time（PT），activated partial thromboplastin time （APTT），fibrinogen （Fib），international normalized ratio （INR），and D-dimer （D-D）. ResultsThere was no significant difference between the two groups regarding 28-day all-cause mortality. After the intervention，SOFA，WBC，PCT，and Cr were significantly decreased， and PLT was significantly increased in the control group （P<0.05）. SOFA，APACHE Ⅱ，NEU%，CRP，PCT，ALT，AST，Cr，BUN，AGI grade，GDS，and serum iFABP and CR were significantly improved in the observation group （P<0.05）. After the intervention，APACHE Ⅱ，PCT，AGI grade，GDS，and serum iFABP in the observation group were significantly lower than those in the control group ，while CR and PLT were higher （P<0.05，P<0.01）. There were significant differences regarding the gap of SOFA，APACHE Ⅱ，AST，TBil，AGI grade，GDS，iFABP，CR， and PLT between the two groups （P<0.05，P<0.01）. There were slight differences regarding PT，APTT，Fib，INR，and D-D between the two groups，which were in the clinical normal range. ConclusionOn the basis of Western medicine， DCH helped to reduce sepsis severity and improved multiple organ dysfunction with high clinical efficacy and safety， but further research on its impact on the prognosis of patients with sepsis is still required.

Objective To investigate the association between baseline depression and the risk of type 2 diabetes mellitus(T2DM)in middle-aged and elderly people in Chengguan District of Lanzhou.Methods A total of 4471 residents who were followed up in Chengguan District,Lanzhou City from August 2014 to July 2016 in the 2011 REACTION study were selected as the research subjects.According to the 9-item patient health questionnaire(PHQ-9),they were divided into the non-depression group with a score of 0～4 points(ND,n=3827),the mild depression group with a score of 5～10 points(MD,n=546)and the moderate to severe depression group with a score of≥10 points(MSD,n=98).The general data and biochemical indicators of the three groups were compared.The correlation between depression status and glycolipid metabolism indicators was analyzed.The follow-up results of the three groups with different baseline glucose metabolism status populations were compared.Logistic regression was used to analyze the influencing factors of progression in different glucose metabolism populations.Results The married rate in the ND,MD and MSD groups decreased sequentially(P<0.05),while the rate of living alone and the PHQ-9 score increased(P<0.05).The female population,family history of DM,coronary heart disease,LDL-C and TC in the MD group were higher than those in the ND group(P<0.05),while the age,BMI,WHR,FPG and 2 hPG in the MD group were lower than those in the ND group(P<0.05).The family history of DM in the MSD group was higher than those in the ND group(P<0.05),drinking and LDL-C in the MSD group were higher than those in the MD group(P<0.05),the BMI was lower than that in the ND group(P<0.05).Spearman correlation analysis showed that the baseline PHQ-9 score was negatively correlated with FPG level(r=-0.039,P<0.05),and positively correlated with HDL-C and TC(r=0.049,0.031,P<0.05).There was no significant difference in the incidence of pre-DM and T2DM at the end of follow-up among the three groups with different baseline glucose metabolism(P>0.05).Logistic regression analysis showed that after adjusting for confounding factors,the risk of pre-DM and T2DM in normal glucose tolerance people with different depression status and the risk of T2DM in pre-DM patients were not increased.Conclusions Depressive state may not be the main factor affecting the occurrence of T2DM in middle-aged and elderly people in Chengguan District of Lanzhou.

OBJECTIVE: To observe the clinical efficacy and safety of automatic pressure-controlled pressure cupping in patients with lumbar disc herniation, and compare it with traditional cupping. METHODS: A total of 100 patients diagnosed with lumbar disc herniation from January 2022 to August 2024 were selected and divided into two groups:the automatic pressure-controlled pressure cupping group (controlled pressure cupping group) and the traditional cupping group (control group), 50 cases in each group. In the controlled pressure cupping group, there were 18 males and 32 females, with an age of (51.98±12.69) years;in the control group, there were 16 males and 34 females, with an age of (51.32±12.05) years. The visual analogue scale(VAS), comfort score, and lumbar range of motion were observed before treatment and after the 1st, 3rd, and 7th treatments to evaluate the efficacy and safety. RESULTS: All patients completed the treatment intervention, with complete follow-up data collected. No adverse reactions or complications occurred during treatment and follow-up. After the 3rd treatment, the VAS score of the controlled pressure cupping group was (2.38±0.49), which was lower than that of the control group (2.94±0.68), with a statistically significant difference (P<0.001). In the controlled pressure cupping group, the VAS scores after the 1st, 3rd, and 7th treatments were significantly better than those before treatment (P=0.026);in the control group, the VAS scores after the 3rd and 7th treatments were better than those before treatment, but the difference was not statistically significant(P=0.182). Repeated-measures analysis of variance (ANOVA) on VAS scores at different time points in both groups showed that there were statistically significant differences in inter-group, time, and interaction effects (P<0.05). After the 1st treatment, in the controlled pressure cupping group, 0 patients felt comfortable, 42 patients (84%) felt mild discomfort, and 8 patients (16%) felt moderate discomfort;in the control group, 0 patients felt comfortable, 28 patients (56%) felt mild discomfort, and 22 patients(44%) felt moderate discomfort;the difference between the two groups was statistically significant(P=0.005). After the 3rd treatment, in the controlled pressure cupping group, 30 patients(60%) felt comfortable, 20 patients (40%) felt mild discomfort, and 0 patients felt moderate discomfort; in the control group, 9 patients (18%) felt comfortable, 41 patients (82%) felt mild discomfort, and 0 patients felt moderate discomfort;the difference between the two groups was statistically significant(P<0.001). There was no statistically significant difference in comfort between the two groups after the 7th treatment(P>0.001). There was no statistically significant difference in lumbar range of motion between the two groups before and after treatment(P>0.05);compared with before treatment, the lumbar range of motion of both groups after treatment was significantly improved, with statistically significant differences (P<0.001).

Objective:Kawasaki disease shock syndrome（KDSS）and macrophage activation syndrome（MAS）are both severe forms of Kawasaki disease. The coexistence of these two critical illnesses is extremely rare，which can be life-threatening in severe cases. The purpose of this study is to summarize the clinical features of children with KDSS complicated with MAS，and provide a basis for precise diagnosis and treatment.Methods:A retrospective analysis was conducted on the clinical manifestations，laboratory tests，imaging characteristics，treatment，and prognosis of 10 children with KDSS and MAS admitted to Beijing Children's Hospital，Capital Medical University from January 2021 to June 2024.Results:Among the 10 children，six were male and four were female，and the age of onset was three months to eleven years old. Acute kidney injury was observed in five patients. Laboratory tests revealed significant increases in serum ferritin，C-reactive protein，B-type natriuretic peptide，aspartate aminotransferase，alanine aminotransferase，creatinine，triglycerides，and interferon-γ，while platelet count and albumin were significantly decreased. Six patients had cardiac enlargement，three had reduced ejection fraction，seven had pericardial effusion，and seven had coronary artery damage. All children were treated with immunoglobulin and methylprednisolone pulse therapy，as well as vasoactive drug infusion to improve circulation and maintain blood pressure. All children were discharged after clinical improvement，and most had a good prognosis.Conclusion:Children with KDSS may develop MAS，which present a complex and rapidly progressing condition often accompanied by a significant increase in ferritin levels. Early diagnosis and treatment can lead to a favorable prognosis.

In recent years,the market share of food and medicine homology substances has continued to grow,and various types of contamination issues have become the focus of attention both inside and outside the industry.The contamination not only affects the original medicinal quality,but also leads to the accumulation of toxic substances in the human body,causing acute and chronic severe hazards such as vomiting,poisoning and cancer.Therefore,the development of biosensors that can conveniently,accurately and sensitively detect various pollutants in food and medicine homology substances has become a research hotspot.Aptasensors based on metal-organic frameworks(MOFs)with advantages such as strong specificity,rapid response and simple operation,have been widely used in detection of various pollutants.This review focused on the research progress of aptasensors based on MOFs for detection of food and medicine homology contamination in the past few years,and provided a detailed comparison and analysis for detection of chemical pollutants(such as pesticide residues,heavy metal residues,mycotoxins,etc.)and microbial contamination in food and medicine homology substances.Besides,the development trend and possible challenges of MOFs aptasensors in detection of food and medicine homology substances in the future were discussed,which was anticipated to provide a reference for the development of new MOFs aptasensors.

Objective To investigate the efficacy of lacosamide combined with ketogenic diet in the treatment of pediatric epilepsy and its impacts on the levels of serum glial fibrillary acidic protein(GFAP)and specific protein of the central nervous system(S-100β).Methods A total of 64 chil-dren with epilepsy from July 2022 to April 2024 were selected and randomly divided into conventional group(n=32)receiving oral lacosamide tablets and combined group(n=32)receiving ketogenic di-et therapy based on the conventional group.The efficacy,cognitive function,and intelligence of chil-dren in both groups after treatment,as well as the levels of serum GFAP and S-100β,the frequency of seizures,and electroencephalogram(EEG)findings before and after treatment were evaluated.Results After treatment,the number of alpha waves,the Full-scale Intelligence Quotient(FIQ)of the Wechsler Intelligence Scale for Children,and the Montreal Cognitive Assessment(MoCA)scores increased in both groups,with a greater increase in the combined group compared to the conventional group,and the differences were statistically significant(P＜0.05).The levels of serum S-100β and GFAP,the frequency of seizures,and the number of cases with slow waves and epileptiform waves decreased after treatmen,and these indicators were lower in the combined group than in the conventional group,with sta-tistically significant differences(P＜0.05).The total effective rate was 90.63％in the combined group and 68.75％in the conventional group,with a statistically significant difference(P＜0.05).The incidence of adverse reactions was 12.50％in the combined group and 9.38％in the conventional group,with no statistically significant difference(P＞0.05).Conclusion Lacosamide combined with ketogenic diet shows good efficacy in the treatment of pediatric epilepsy,and the combined therapy improves neurological function by synergistically reducing the levels of GFAP/S-100β.

Objective To explore the correlation between blood biochemical indexes and blood pressure levels among college students in Kunming City.Methods In November 2021,a cluster sampling method was used to survey 4,781 college students at a university in Yunnan Province.Data collected included height,weight and blood pressure,and blood samples were collected for blood biochemical testing.The Mann-Whitney U test and Kruskal-Wallis H test were used to compare the distribution differences of hypertension among college students with different demographic characteristics,while a generalized linear model was used to analyze the correlation between blood biochemical indicators and blood pressure levels.Results The prevalence rate of hypertension among college students was 8.45%(404/4 781).After adjusting confounding variables,blood glucose(GLU,β=1.48,95%CI:0.75～2.20)and serum Total Protein(TP,β=0.25,95%CI:0.19～0.32)were found to be correlated with systolic blood pressure(SBP)levels(all P<0.05);blood glucose(GLU,β=1.25,95%CI:0.64～1.86)and serum total protein(TP,β=0.28,95%CI:0.23～0.34)were correlated with diastolic blood pressure(DBP)level(P<0.05).Stratified group analysis by sex showed that,after controlling for confounding factors,TP(β=0.32,95%CI:0.18～0.45)was correlated with SBP levels in male students;TP(β=0.32,95%CI:0.21～0.43)was correlated with DBP levels in male students(P<0.05).GLU(β=2.18,95%CI:1.29～3.07)and TP(β=0.23,95%CI:0.15～0.31)were correlated with SBP levels in female students;GLU(β=1.48,95%CI:0.73～2.24)and TP(β=0.26,95%CI:0.20～0.33)were correlated with DBP levels in female students(all P<0.05).Conclusion Our findings suggest that blood glucose and serum total protein level are correlated with blood pressure levels in female college students,while serum total protein level are correlated with blood pressure levels in male college students.

Lipoatrophic diabetes(LD) is a rare and distinct form of diabetes characterized by notable clinical heterogeneity. It is often considered one of the manifestations of lipodystrophy syndrome(LDS). In clinical practice, LD is frequently misdiagnosed as type 2 diabetes; however, its management protocols and prognostic outcomes differ significantly from those of other diabetes subtypes. Therefore, timely and accurate diagnosis is of great clinical importance. This paper presents two detailed case reports of female patients with LD. Through an in-depth analysis of their clinical features, it also provides an comprehensive review of the key clinical manifestations of LDS, potential pathogenic mechanisms, and current approaches to genetic diagnosis. The aim is to enhance clinicans′ awareness of LDS and improve corresponding diagnostic and therapeutic strategies.

Objective:To construct a nanoparticle vaccine displaying the prefusion F (preF) protein of respiratory syncytial virus (RSV) using the I53-50 protein nanoparticle platform, and to systematically evaluate its immunogenicity and protective efficacy.Methods:The RSV preF trimer antigen was genetically fused to I53-50A and assembled in vitro with I53-50B to form preF-I53-50 nanoparticles, theoretically displaying 20 preF antigens per particle. The structure and purity were characterized by size-exclusion chromatography, SDS-PAGE, and negative-stain electron microscopy. BALB/c mice were intramuscularly immunized with varying doses (1 μg or 5 μg) of preF antigen or an equimolar amount of preF-I53-50 nanoparticles. Humoral immunity, B-cell responses, and protective efficacy were assessed following intranasal viral challenge.Results:The preF-I53-50 nanoparticles self-assembled into spherical structures (50-60 nm in diameter) with uniformly arrayed antigens. The nanoparticle vaccine enhanced RSV-specific IgG1 and IgG2a antibody responses, promoting a Th1-biased immune profile. At equimolar preF doses, the neutralizing antibody titers induced by 1 μg and 5 μg nanoparticle formulations were 2.8-fold and 2.3-fold higher, respectively, than those elicited by preF alone ( P<0.05). Notably, even the low-dose nanoparticle group outperformed the high-dose preF group (1.6-fold increase). Viral challenge experiments demonstrated that preF-I53-50 effectively suppressed pulmonary viral replication, mitigated pathological damage, and induced stronger germinal center and memory B-cell responses, suggesting enhanced B-cell affinity maturation and long-term immune memory. Conclusion:The preF-I53-50 vaccine improves the immunogenicity and protective efficacy of RSV preF through multivalent antigen display.

The study aimed to construct the second and third generation chimeric antigen receptor T cells (CAR-T) targeting the c-mesenchymal-epithelial transition factor (c-Met) protein, and observe their killing effect on human serous ovarian cancer cell SKOV-3. The expression of MET gene in ovarian serous cystadenocarcinoma, the correlation between MET gene expression and the abundance of immune cell infiltration, and the effect of MET gene expression on the tissue function of ovarian serous cystadenocarcinoma were analyzed by bioinformatics. The expression of c-Met in ovarian cancer tissues and adjacent tissues was detected by immunohistochemical staining. The second and third generation c-Met CAR-T cells, namely c-Met CAR-T(2G/3G), were prepared by lentivirus infection, and the cell subsets and infection efficiency were detected by flow cytometry. Using CD19 CAR-T and activated T cells as control groups and A2780 cells with c-Met negative expression as Non target groups, the kill efficiency on SKOV-3 cells with c-Met positive expression, cytokine release and cell proliferation of c-Met CAR-T(2G/3G) were explored by lactate dehydrogenase (LDH) release, ELISA and CCK-8 respectively. The results showed that MET gene expression was significantly up-regulated in ovarian cancer tissues compared with normal tissues, which was consistent with the immunohistochemistry results. However, in all pathological stages, there was no obvious difference in MET expression and no correlation between MET gene expression and the race and age of ovarian cancer patients. The second generation and third generation c-Met CAR-T cells were successfully constructed. After lentivirus infection, the proportion of CD8⁺ T cells in c-Met CAR-T(2G) was upregulated, while there was no significant change in the cell subsets of c-Met CAR-T(3G). The LDH release experiment showed that the kill efficiency of c-Met CAR-T(2G/3G) on SKOV-3 increased with the increase of effect-target ratio. When the effect-target ratio was 20:1, the kill efficiency of c-Met CAR-T(2G) reached (42.02 ± 5.17)% (P < 0.05), and the kill efficiency of c-Met CAR-T(3G) reached (51.40 ± 2.71)% (P < 0.05). ELISA results showed that c-Met CAR-T released more cytokine compared to CD19 CAR-T and activated T cells (P < 0.05). Moreover, the cytokine release of c-Met CAR-T(3G) was higher than c-Met CAR-T(2G) (P < 0.01). The CCK-8 results showed that after 48 h, the cell number of c-Met CAR-T(2G) was higher than that of c-Met CAR-T(3G) (P < 0.01). In conclusion, both the second and third generation c-Met CAR-T can target and kill c-Met-positive SKOV-3 cells, with no significant difference. c-Met CAR-T(2G) has stronger proliferative ability, and c-Met CAR-T(3G) releases more cytokines.
