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:Childhood traumatic experiences greatly influenced the brain network activities of patients with depression,and there is an urgent need to explore the temporal dynamics for these changes.This study aims to investigate the abnormalities of resting-state electroencephalogram(EEG)microstates in eye-open state of depressed adolescents and to explore the correlations between their EEG microstates and the childhood traumatic experience. Methods:Using resting-state EEG microstate analysis,we explored the temporal dynamics of brain activity in patients with adolescent depression.This study selected 66 adolescents with depression as a patient group,and 27 healthy adolescents as a healthy control group.A modified k-means clustering algorithm was used to classify the 64-channel resting-state EEG data into different microstates.Independent sample t-tests were used to compare the microstate parameters between the 2 groups and further assciations between these parameters and childhood traumatic experience in patients were explored via using Spearman correlation. Results:In this study,significant differences were observed in the occurrence and transition probabilities of EEG microstates between the healthy control and the patient group.Notably,there was a statistically significant difference(P<0.05)in the occurrence of microstate A across 2 groups,exhibiting a negative correlation with the emotional abuse component within the childhood trauma scores(Spearman's rho=-0.31,P=0.013).Furthermore,patient-specific,non-random transitions from microstate B to A(Spearman's rho=-0.30,P=0.015)and C to A(Spearman's rho=-0.31,P=0.013)were inversely associated with the scores of emotional abuse factors from childhood trauma in the patient group,showing statistically significant differences when comparing to the healthy controls(P<0.05).Upon stratification into quartiles based on the emotional abuse factor scores,the occurrence of microstate A,as well as the transition rates from microstates B to A and C to A,retained statistical significance following adjustment for multiple comparisons(all P<0.05). Conclusion:The abnormal temporal dynamics in brain networks of adolescents with depression are linked to childhood emotional abuse.Those who have suffered severe emotional abuse may show greater impairments in the brain's visual and central executive networks.EEG microstate analysis could be a potential tool for detecting adolescent depression with severe childhood trauma.

Objective:To investigate the predictive value of mechanism Glasgow age blood pressure score (MGAPS), revised trauma score (RTS) and modified rapid emergency medicine score (mREMS) in predicting the mortality risk of patients with acute traumatic brain injury (TBI) within 24 hours.Methods:A case control study was performed for clinical data of 1 156 patients with acute TBI admitted to Affiliated Hospital of Nantong Hospital from January to December of 2020, including 745 males and 411 females; aged 18-100 years [(59.9±15.1)years]. Glasgow coma score (GCS) was 3-15 points [15(9, 15)points]. The patients were divided into death group ( n=87) and survival group ( n=1 069) according to death or not within 24 hours. Vital signs, general data, MGAPS, RTS and mREMS were documented at emergency visit. Differences in the specific scores and severity levels of the patients using the three scoring systems were compared between the two groups. Receiver operating characteristic (ROC) curve was plotted for the three scoring systems based on the specific scores and severity levels of the patients. While the area under the curve (AUC), sensitivity, specificity, optimal threshold and Youden index were determined to estimate the value of the three scoring systems in predicting death risk in patients with acute TBI within 24 hours. Results:Death group showed significantly decreased scores in MGAPS [17(12, 19)points] and RTS [5.0(4.1, 6.0)points] and significantly increased score in mREMS [9(7, 12)points] when compared with survival group (all P<0.01). The proportion of moderate- and high-risk patients for MGAPS and proportion of high-risk patients for RTS and mREMS in death group were significantly higher than those in survival group (all P<0.01). As indicated by the ROC curve plotted based on the specific scores, mREMS had the maximum AUC (0.88), followed by MGAPS (0.86) and RTS (0.86); the sensitivity of mREMS, MGAPS and RTS was similar (80.5%, 86.2% and 82.8%, respectively), while mREMS showed the highest specificity (83.4%) compared to MGAPS (78.0%) and RTS (82.3%); the optimum threshold of mREMS, MGAPS and RTS, was 6 points, 6.08 points and 20 points; the Youden index of MGAPS, RTS and mREMS was 0.64, 0.64 and 0.65. As indicated by the ROC curve plotted based on the injury severity, MGAPS had the highest AUC (0.84), followed by RTS (0.70) and mREMS (0.59); MGAPS also had the highest sensitivity (92.0%), higher than RTS (47.1%) and RTS (18.4%); when mREMS showed the highest specificity(98.8%) compared to RTS (93.7%) and MGAPS (68.8%); the optimal threshold of MGAPS, RTS and mREMS was 22 points, 4 points and 13 points; the Youden index of MGAPS, RTS and mREMS was 0.61, 0.41 and 0.17. Conclusions:MGAPS, RTS and mREMS can be predictive in assessing the mortality risk of patients with acute TBI within 24 hours. mREMS has the highest prediction value, with an optimal threshold of 6 points when the risk assessment is made in accordance with specific scores of the patients. MGAPS has the highest prediction value when the risk assessment is assessed by the injury severity.

Objective:To explore the critical value of different blood group antibody titration in ABO blood group incompatible kidney transplant(ABOi-KT)recipients by tube and gel methods to provide rationales for selecting the threshold value of antibody titration before ABOi-KT.Methods:From January 2019 to April 2021, 681 blood group antibody titrations were performed for 214 ABOi-KT recipients.There were type A( n=135), type B( n=168)and type O( n=378). The difference, correlation and consistency of two methods were statistically analyzed. Results:Tube method was 2 gradients lower than gel method(4-fold dilution)and the results were significantly different( P<0.000 1). Spearman's test indicated that the results of two methods were significantly correlated( P<0.000 1). The results of intraclass correlation coefficient showed that the consistency of two methods was general for type A recipients(ICC=0.640), decent for type B recipients(ICC=0.751)and poor for type O recipients(ICC<0.4). When the critical value of tube method was set, titration of type A anti-B was 16, titration of type B anti-A 8 and titration of type O anti-A/B 8.And the corresponding critical values of gel was type A anti-B 32, type B anti-A 16 and type O anti-A/B 16. Conclusions:The results of ABO blood group IgM antibody titration by gel and tube methods are correlative.And gel method is recommended for more stable and reproducible results.

Objective:To explore the carrier status of carbapenems-resistant Klebsiella pneumoniae (CRKP) plasmids in burn patients and analyze the correlation of these plasmids with the transmission of CRKP. Methods:A retrospective observational study was conducted. A total of 26 CRKP strains, which were isolated from the clinic-related samples of 22 burn patients (with 20 males and 2 females, aged (42±16) years) admitted to the First Affiliated Hospital of Army Medical University (the Third Military Medical University) from January to December 2017, were collected and individually numbered. The plasmids of the strains were extracted by alkali lysis. After determination of the plasmid concentration by a nucleic acid concentration detector, the agarose gel electrophoresis was used to visualize the bands, and rough plasmids typing was performed. The plasmid of the smallest numbered CRKP in each plasmid type was transformed into competent Escherichia coli ( E. coli) strain Top10 (hereinafter referred to as TOP10 strain). The growth of each transformed strains and a Top10 strain cultivated in ampicillin containing Luria-Bertani (LB) agar medium overnight was observed, and the proportion of successful transformation was calculated. The plasmids from the smallest numbered plasmid carrying CRKP strain of successfully transformed Top10 strains (hereinafter referred to as the smallest successfully transformed strain) and correspondingly numbered CRKP were extracted, and then, the agarose gel electrophoresis was used to visualize the bands. Aforementioned successfully transformed strains and a TOP10 strain were used for the antimicrobial susceptibility testing with 17 antibiotics commonly used in clinic. The plasmid from the smallest successfully transformed strain was sequenced using the next-generation sequencing technology. Bioinformatics analyses such as protein-coding gene prediction and protein sequence alignment were performed successively. The sequence was subsequently named pKP03-NDM1 according to the carrying of drug resistance gene. According to the whole genome sequence of the plasmid carried by the smallest successfully transformed strain, the polymerase chain reaction, agarose gel electrophoresis, and gene sequencing were used to detect the New Delhi metallo-beta lactamase-1 ( blaNDM-1) of plasmids in the remaining 25 strains of CRKP. The ST typing in multilocus sequence typing of 26 strains of CRKP was analyzed based on the literature. Results:Plasmids were successfully extracted from 26 CRKP, with mass concentrations ranging from 19.3 to 189.8 ng/μL. Each of the 26 CRKP carrying plasmids showed at least one band longer than 2 500 bp in the agarose gel electrophoresis, which were roughly divided into 6 patterns of A, B, C, D, E, and F. After overnight cultivation, no growth of strains was observed in LB agar medium containing ampicillin inoculated with the TOP10 strain or TOP10 strains transformed by the plasmid of CRKP patterning A, B, D, or E. In contrast, TOP10 strains transformed by the pattern C plasmid from NO.3 CRKP and the pattern F plasmid from NO.15 CRKP resulted in numerous colony growths, and those transformed strains were named as TOP10-pKP03 and TOP10-pKP15, respectively. The proportion of successful transformation was 1/3. The plasmid carried by TOP10-pKP03 showed a single band in the agarose gel electrophoresis, which was the same size as the largest band of the plasmid from NO.3 CRKP. The TOP10 strain was sensitive to the 17 antibiotics commonly used in clinic. TOP10-pKP03 and TOP10-pKP15 were resistant to penicillins, cephalosporins, and carbapenems but remained sensitive to monocyclic β-lactam, aminoglycosides, quinolones and tigecycline. The full length of the plasmid carried by TOP10-pKP03 was 41 190 bp. In addition to blaNDM-1, this plasmid carried bleMBL, T4SS, bleomycin resistance gene, conjugation transfer elements, and relaxase, etc. The plasmid showed 99% nucleotide identity similarity and the same length to the plasmid pJN24NDM1 extracted from an E. coli isolate JN24. Totally 16 (61.5%) CRKP were confirmed to carrying blaNDM-1 gene, among the ST typing of the 16 strains, 11 strains were ST11, while ST215, ST260, ST395, ST2230, and new ST had 1 strain each. Among the ST typing of 10 blaNDM-1-negative CRKP, 8 strains were ST11, while ST395 and ST2230 had 1 strain each. Conclusions:A blaNDM-1 gene carrying plasmid pKP03-NDM1 was extracted and sequenced from CRKP isolated from burn patients, with a high plasmid carrying rate. Meanwhile, this plasmid may mediate inter-CRKP and CRKP- E. coli horizontal transfer of blaNDM-1, leading to transmission of antimicrobial resistance.

Objective:To observe the occurrence of epithelial-mesenchymal transition (EMT) in cervical cancer cell line Siha irradiated by X-rays with clinical conventional fraction radiotherapy model and investigate the role of exosomes in this process.Methods:Siha cells were irradiated by 6 MV-X rays with 50 Gy in 25 fractions. EMT was evaluated by cell morphology, EMT biomarkers and cell migration and invasion ability. Exosomes released from cells were detected by transmission electron microscopy and nanoparticle tracking analysis (NTA), and its function in EMT was explored by using an exosome inhibitor GW4869 (10 μmol/L).Results:After irradiation, EMT phenomenon was induced in the survived Siha cells, including the incidence of mesenchymal phenotype, upregulation of epithelial marker E-cadherin ( t=9.66, P<0.05), downregulation of mesenchymal marker N-cadherin ( t=41.61, P<0.05), and increase of cell migration and invasion abilities ( t=6.11, 13.22; P<0.05). Meanwhile, the secretion of exosomes was also increased after irradiation ( t=7.51, P<0.05). When the cells were pre-treated with GW4869, radiation-induced exosome secretion was reduced ( t=7.28, P<0.05), so that radiation-induced EMT was reversed. Conclusions:Ionizing radiation with clinical conventional fraction radiotherapy model promotes EMT of cervical cancer cells through increasing the secretion of exosomes.

Objective:To investigate the characteristics and change trends of electroencephalogram (EEG) in patients with drug resistant epilepsy (DRE) after vagus nerve stimulation (VNS).Methods:Twenty-five patients with DRE, admitted to our hospital from July 2016 to May 2019, were chosen; all patients accepted VNS and followed up for 12 months. Long range video EEG (VEEG) monitoring was performed before VNS, and 3, 6 and 12 months after VNS, and the tracing time of each monitoring was longer than 12 h. The EEG characteristics of these patients before and different times after VNS were analyzed.Results:In the VEEG monitoring before VNS, 25 patients showed sharp wave, spike wave, sharp slow wave, and compound spike slow wave in the interictal period; 3 patients (12%) could locate the brain region. The interictal EEG of 11 patients 3 months after VNS showed different degrees of improvement as compared with the preoperative one, which manifested as mixed rhythms: mono-spiking as sharp wave, sharp slow wave or spike wave; 8 patients had McHugh grading I-II. The interictal EEG of 18 patients 6 months after VNS showed different degrees of improvement as compared with the preoperative one; 11 patients had McHugh grading I-II. The interictal EEG of 21 patients 12 months after VNS showed different degrees of improvement as compared with the preoperative one; 15 patients had McHugh grading I-II.Conclusion:The EEG improvement effect of DRE patients after VNS is gradually improved with time; in some patients, the EEG improvement is earlier than improvement of clinical symptoms.
