A 70-year-old female patient with tumor in the neck and body of the pancreas received 11 cycles of chemotherapy with paclitaxel and gemcitabine. Due to disease progression, she subsequently underwent chemotherapy of fluorouracil, calcium folinate, and irinotecan, combined with immunotherapy of serplulimab. After 28 days (only one session of immunotherapy), the patient developed drooping of the right upper eyelid and chest tightness, followed by pain in the middle and lower segments of the sternum and radiating pain to the throat, accompanied by speech difficulties, dysphagia, and chest tightness and wheezing. Laboratory tests indicated hypersensitive troponin T 0.551 μg/L, creatine kinase (CK) 3 426 U/L, CK-MB 176 μg/L, and myoglobin 1 702 μg/L. The imaging examination of head and neck ruled out intracranial lesions, while the electrocardiogram suggested myocardial damage. Immune-related myocarditis with myositis and/or myasthenia gravis overlap syndrome (IM3OS) induced by serplulimab was considered. Immunotherapy was temporarily halted, and treatments with methyprednisolone and human immunoglobulin were administered. Sixteen days later, clinical symptoms of IM3OS in the patient were improved, with laboratory tests showing hypersensitive troponin I 0.075 μg/L, CK 216 U/L, CK-MB 58 μg/L, and myoglobin 273 μg/L. Upon follow-up, the patient switched to monotherapy with irinotecan alone or combined with raltitrexed for cancer treatment, clinical symptoms of IM3OS did not recur, and no abnormalities were observed in myocardial injury markers or muscle enzymes.

Objective:To study the resistance of Aedes albopictus to commonly used insecticides in Hangzhou, and to investigate the polymorphism distribution characteristics of voltage-gated sodium channel (VGSC) and acetylcholinesterase (AchE) 1 (Ace-1) genes in Aedes albopictus in the region, providing a scientific basis for control of Aedes albopictus in Hangzhou. Methods:From May to June 2023, Aedes albopictus larvae and pupae were collected from residential areas across divided different urban areas by directions in Hangzhou. They were reared in the laboratory, and their resistance to malathion, propoxur, pyrethroid insecticides (permethrin, deltamethrin, and beta-cypermethrin) was evaluated using the World Health Organization-recommended adult mosquito contact tube method. The 24 h mortality rates of adult mosquito of 98% - 100% was susceptible, 80% - < 98% was suspected resistance, < 80% was resistant. Genomic DNA was extracted from adult Aedes albopictus, and mutations in the VGSC and Ace-1 genes were detected through PCR amplification and Sanger sequencing. Results:The 24 h mortality rates of adult Aedes albopictus exposed to 0.5% malathion, 0.05% propoxur, 0.4% permethrin, 0.03% deltamethrin, and 0.08% beta-cypermethrin in Hangzhou were 100% (75/75), 96.00% (72/75), 41.43% (29/70), 17.33% (13/75), and 32.86% (23/70), respectively. A total of 146 surviving Aedes albopictus were tested for VGSC gene mutations at diagnostic doses of pyrethroid insecticides. Among them, 6 Aedes albopictus (4.11%) had a gene mutation at position V1016, and 146 Aedes albopictus (100%) had a gene mutation at position F1534. A total of 63 Aedes albopictus that died at diagnostic doses of pyrethroid insecticides were analyzed for VGSC gene mutations. No gene mutation was detected at position V1016, while 63 Aedes albopictus (100%) had a gene mutation at position F1534. One non synonymous mutation was detected at position V1016 of the VGSC gene, which was a heterozygous mutation of V1016V to V1016V/G. Two non synonymous mutations were detected at position F1534 of the VGSC gene, namely F1534F to F1534S or a F1534F/S heterozygous mutation. No Ace-1 gene mutation was detected in all Aedes albopictus exposed to 0.05% propoxur ( n = 75). Conclusions:The Aedes albopictus in Hangzhou has developed resistance to permethrin, deltamethrin, and beta-cypermethrin. It shows suspected resistance to propoxur and sensitivity to malathion. Moreover, a high frequency of mutations in the VGSC gene has been observed in these mosquitoes. It is crucial to enhance resistance monitoring in Aedes albopictus populations in Hangzhou and to implement the rational rotation of chemical insecticides to slow down the progress of drug resistance.

Objective To investigate the serum amino acid levels in patients with acute schizophrenia(SCZ)and their predictive effect on the improvement of cognitive function after treatment,so as to provide new insights into the clinical intervention of cognitive impairment in SCZ patients.Methods A total of 66 patients with acute SCZ were enrolled(case group-baseline period).Among them,36 cases completed the follow-up after 3 months of standardized treatment(case group-follow-up period);52 healthy controls(HCs)were included.The MATRICS Consensus Cognitive Battery(MCCB)was used to assess the cognitive function of all the participants.Liquid chromatography-tandem mass spectrometry(LC-MS)was employed to detect the concentrations of 18 amino acids in fasting serum of the case group-baseline period and the control group.Independent samples t-test was used to compare serum amino acid levels and cognitive function between the case group-baseline period and the control group.Paired t-test was used to compare the differences in cognitive function between the baseline period and the follow-up period of the case group.Spearman correlation analysis and multivariate linear regression model were used to investigate the correlation between serum amino acid levels at baseline in the case group and the improvement of cognitive function after 3 months of treatment.Results Compared with the control group,the cognitive function of SCZ patients in multiple dimensions at baseline was significantly reduced(P＜0.05).After treatment,the scores of Trail Making Test(TMT),Brief Assessment of Cognition in Schizophrenia:Symbol Coding(BACS),Wechsler Memory Scale-Ⅲ(WMS),and Brief Visuospatial Memory Test-Revised(BVMT)in patients were significantly improved(all P＜0.05).In addition,the levels of proline,methionine,histidine,phenylalanine,arginine,tyrosine,aspartic acid,tryptophan,lysine,and glutamic acid were significantly lower in the case group at baseline than in the control group(all P＜0.05).Among them,the baseline tyrosine level had a significant predictive value for the improvement of TMT(R2=0.136,P=0.029),Neuropsychological Assessment Battery(NAB)(R2=0.339,P＜0.001),and Mayer-Salovey-Caruso Emotional Intelligence Test(MSCEIT)test(R2=0.165,P=0.015).The baseline arginine level had a significant predictive value for the improvement rate of Fluency test(R2=0.113,P=0.048).Conclusion There is a decrease in various amino acid levels in patients with SCZ,and some amino acids can effectively predict the improvement of cognitive function after treatment.

Objective To explore the risk factors of acute respiratory failure(ARF)in adult patients with community-acquired pneu-monia(CAP),and thereby construct and validate the efficacy of nomogram model.Methods The clinical and laboratory data of 172 adult CAP patients admitted to Taikang Xianlin Drum Tower Hospital affiliated to Nanjing University School of Medicine from January 2018 to December 2021 were retrospectively collected.The patients were divided into two groups based on whether they had concurrent ARF.After the comparison for the differences of single factor between the two groups,collinearity analysis was assessed.The risk fac-tors were then screened by binary logistic regression analysis with forward stepwise regression method.A nomogram model was subse-quently constructed and the discrimination and accuracy of the model were evaluated by ROC and colibration curves.Results Among the 172 CAP patients,53 cases(30.8％)developed ARF.The results of univariate analysis showed that the CAP patients with concur-rent ARF group had higher age,CURB-65 score and inflammatory markers than the non-concurrent ARF group,and the incidence of complex infection(culturing two or more pathogenic bacteria)was high.The values of CRP(C-reactive protein)and BUN/Alb(blood urea nitrogen/albumin)were significantly different between the two groups(53.910[25.900,101.200]vs.23.300[6.800,48.930],0.231[0.160,0.302]vs.0.123[0.089,0.171],P＜0.05).Multivariate analysis indicated:glucose(Glu)≥6.06 mmol/L(odds ra-tio(OR):2.737,95％confidence interval(CI):1.116-7.037),AST(aspartate aminotransferase)≥22.5 U/L(OR:4.291,95％CI:1.779-11.120),fibrinogen(Fib)≤3.83 g/L(OR:3.955,95％CI:1.631-10.237),uric acid(UA)188.07 μmol/L(OR:4.617,95％CI:1.859-12.489),BUN/Alb≥0.15 mmol/g(OR:6.381,95％CI:2.423-18.513),total number of multicomor-bidity≥3(OR:6.191,95％CI:2.088-21.905)were the risk factors(P＜0.05).All the screened indicators were incorporate into the nomogram model and its efficacy was verified.The results showed that the area under the curve of the model was 0.888[95％CI:0.840-0.935](P＜0.05),the sensitivity was 0.868,and the specificity was 0.790.The calibration curve showed that the predicted probability of adult CAP patients-associated with ARF was in good consistency with the observed probability(Briser Score:0.125;H-L test:x2=7.563,P=0.477).Conclusion The established model has a good ability to predict adult CAP associated with ARF,and can provide a reference basis for early clinical prediction and intervention treatment.

Objective To analyze the health economics of ultra-short wave therapy adjuvant to drug therapy for acute pharyngitis,and to provide a more cost-effective treatment option for clinical management.Methods Seventy patients with acute pharyngitis were randomly divided into a control group(35 cases)and an ultra-short wave group(35 cases).The control group received conventional drug therapy,while the ultra-short wave group received ultra-short wave therapy in addition to conventional drug therapy.The cure rate,treatment duration,direct costs,indirect costs,and total costs were compared between the two groups for clinical efficacy and health economics analysis.Results The cure rate in the ultra-short wave group was significantly higher than that in the control group(P=0.008),while the total treatment cost and treatment duration were significantly re-duced.To achieve the same therapeutic effect,the ultra-short wave group required 129.73 yuan less than the control group.Conclusion Ultra-short wave therapy adjuvant to conventional drug treatment for acute pharyngitis can more rapidly alleviate symptoms,reduce indirect costs due to work absence,without significantly increasing treatment expenses.It is a safe,effective,and economical therapy with higher therapeutic value compared to drug therapy alone,and is worthy of widespread promotion.

Objective To investigate the modulatory effects of transcranial direct current stimulation(tDCS)on directional informa-tion flow within the α-band functional brain networks in patients with disorders of consciousness(DoC).Methods From October,2023 to October,2024,30 patients with DoC were recruited from Binzhou Medical University Hospital.They were assigned to minimally conscious state(MCS)group(n=15)and unresponsive wakefulness syndrome(UWS)group(n=15).All the patients received conventional rehabilitation and tDCS at left dorsolater-al prefrontal cortex for four weeks.Ten-minute electroencephalography data were collected before and after treat-ment.Results Two cases dropped out from MCS group.Granger causality(GC)connectivity between the prefrontal and pari-etal regions enhanced in both groups after treatment,particularly in bidirectional pathways between bilateral pre-frontal and parietal regions,as well as between frontocentral and parietal regions,and limbic-central connections.GC connectivity was extensive and bidirectional in MCS group,and localized and unidirectional in UWS group.Conclusion tDCS can enhance directional information flow between bilateral prefrontal and parietal regions in patients with DoC,for promoting recovery of consciousness.Neural plasticity was better in MCS patients than in UWS patients.
