ABSTRACT

ObjectiveTo provide technical support for the molecular surveillance of pathogenic bacteria strains carrying mobile colistin resistance-1 (mcr⁃1) gene isolate from inlet of wastewater treatment plants (WWTP). MethodsThe Enterobacteriaceae strains carrying mcr⁃1 resistance gene isolate from inlet of WWTP during April 1 to June 30, 2023 in Shanghai were cultured on blood-rich and SS culture medium and were identified using a mass spectrometry analyzer. The mcr⁃1 gene and copy number were detected by real-time fluorescence quantitative PCR. Drug susceptibility test was performed by microbroth dilution method. The copy numbers of Escherichia coli carrying mcr⁃1 gene isolated from wastewater and human fecel were statistically analyzed by SPSS 25.0. ResultsA total of 14 strains carrying the mcr⁃1 gene were isolated from 49 WWTP samples, and the positive isolation rate was 28.6%, including 12 non-diarrheal E. coli strains and 2 Klebsiella pneumoniae strains. The drug susceptibility results showed that all 14 strains were multi-drug resistant bacteria. They were all sensitive to imipenem and tigecycline, but were ampicillin- and cefazolin-resistant. There was no significant difference in the copy number between human-sourced diarrheal E. coli and wastewater-sourced non-diarrheal E. coli (t=0.647, P>0.05). ConclusionThe isolation and identification of strains carrying the mcr⁃1 gene from inlet of WWTP samples were firstly established in Shanghai. The multi-drug resistance among the isolated strains is severe. To effectively prevent and control the spread of colistin-resistant bacteria, more attention should be paid to the surveillance of mcr⁃1 gene.

ABSTRACT

【Objective】 To explore the prognostic impact and clinical application value of therapeutic plasma exchange(TPE) intervention timing and liver injury periodization in patients with exertional heat stroke(EHS). 【Methods】 Data of 127 EHS patients from the First Medical Center of the General Hospital of the People′s Liberation Army from January 2011 to December 2023 were collected, then divided into the death group and the survival group based on therapeutic outcomes and into 5 stages according to the dynamic changes of ALT, AST, TBIL and DBIL. According to propensity score matching analysis, 11 patients in the survival group and 12 patients in the death group were included in the statistical analysis, and 20 of them were treated with TPE. The changes in indicators and clinical outcomes before and after TPE were observed, in order to evaluate the impact of intervention timing on prognosis. 【Results】 Among the 23 patients, 14 had no liver injury or could progress to the repair phase, resulting in 3 deaths(with the mortality rate of 21.43%), while 9 patients failed to progress to the repair phase, resulting in 9 deaths(with the mortality rate of 100%), with significant differences(P<0.05). The mortality rate of the first TPE intervention before the third stage of liver injury was 23.08%(3/13), while that of intervention after reaching or exceeding the third stage was 85.71%(6/7), and the difference was statistically significant(P<0.05). 【Conclusion】 TPE should be executed actively in EHS patients combined with liver injury before the third phase to lock its pathological and physiological processes, thereby improving prognosis and reducing mortality.

ABSTRACT

【Objective】 To review the occurrence of allergic reactions during therapeutic plasma exchange (TPE) and to explore the risk factors of TPE allergic reactions. 【Methods】 The clinical data of 929 patients treated with TPE using plasma components by the Department of Transfusion Medicine in our medical center from 2018 to 2023 were collected. The influencing factors of allergic reactions were analyzed by univariate analysis, and the independent risk factors of allergic reactions were analyzed by logistic multivariate regression analysis. 【Results】 A total of 4 071 TPEs were performed in 929 patients.Among them, 198 patients (21.31%) experienced 349 times (8.57%) of allergic reactions, with the incidence of grade Ⅰ, Ⅱ and Ⅲ allergic reactions of 16.33%, 81.38% and 2.29%, respectively, and no deaths. The univariate analysis showed that the patient′s age, allergy history, diagnosis of immune-related diseases, ICU admission, plasma consumption, total blood volume, maximum blood flow rate and combined use of albumin were related to the occurrence of allergic reactions (P<0.05). Multivariate regression analysis showed that young patients, a history of allergy, immune-related diseases and non-ICU patients were prone to allergic reactions in TPE, but the treatment options of TPE such as substitute fluid category, plasma consumption and blood flow rate were not related to the occurrence of allergic reactions. 【Conclusion】 There are significant individual differences in the occurrence of allergic reactions for TPE, and young age, history of allergies, immune-related diseases and non-ICU patients are risk factors for allergic reactions in TPE. Identifying patients with risk factors before TPE treatment and giving corresponding preventive measures can reduce the incidence of allergic reactions.

ABSTRACT

ObjectiveTo understand the presence of virulence genes, molecular typing characteristics, and antibiotic sensitivity of enteroaggregative Escherichia coli (EAEC) in children with diarrhea in Shanghai, so as to provide a scientific basis for EAEC monitoring and standardized treatment of EAEC infection. MethodsEAEC strains isolated from children (≤5 years old) with diarrhea in six districts of Shanghai were collected as the study subjects. EAEC virulence genes were detected by real-time fluorescence quantitative PCR, molecular typing was performed by pulsed-field gel electrophoresis (PFGE), and drug susceptibility tests were conducted using the microbroth dilution method. χ2 test and two independent samples t-test were used to compare the differences in virulence genes and antibiotic resistance between suburban and urban EAEC strains. ResultsFrom 2019 to 2021, the overall detection rates of gene aggR, pic and astA of 59 EAEC were 30.5%, 50.8%, and 57.6%, respectively. There was no significant difference in the detection rates of virulence genes between suburban and urban EAEC strains (P>0.05). PFGE analysis revealed that only two EAEC strains belonged to the same PFGE pattern and were collected from the same hospital, and the overall PFGE patterns were polymorphic. EAEC showed susceptibility to imipenem and colistin E, and the resistance rates to sulfamethoxazole (SXT), ampicillin (AMP), nalidixic acid (NAL), and tetracycline (93.1%, 79.3%, 63.8%, and 58.6%, respectively) were higher than 50.0%. The antibiotic resistance rates of cefazolin (CFZ), cefotaxime (CTX), and ciprofloxacin (CIP) were significantly different between EAEC strains from suburban and urban areas (P<0.05). A total of 47 strains exhibited multi-drug resistance, with the most common resistance spectrum being AMP-SXT-NAL. There was no statistically significant difference in the number of multidrug-resistant EAEC strains between suburban and urban areas (P>0.05). ConclusionThe EAEC virulence gene assemblages in children with diarrhea in the six districts of Shanghai are diverse, and the molecular typing patterns are relatively scattered, indicating possible cross-infection of homologous strains. Multi-drug resistance in EAEC strains is relatively common, and there is a statistically significant difference in the resistance rates of CFZ, CTX and CIP between urban and suburban EAEC strains. Attention should be given to standardizing the use of clinical antibiotics to effectively control the dissemination of multidrug-resistant EAEC strains.

ABSTRACT

【Objective】 To evaluate common laboratory items in a large-dose blood loss model in vitro using thromboelastogram (TEG), to provide a reasonable infusion solution for clinical massive transfusions. 【Methods】 On March 2nd, 2017, eight healthy blood donors who participated in voluntary blood donation in the Department of Blood Transfusion Medicine of the First Medical Center of the PLA General Hospital were selected to undergo phlebotomy, and an in vitro dilution model of massive blood loss was established based on the previous research, namely Model 1 (M1, given massive transfusion protocol) and Model 2 (M2, given packed red blood cells and plasma) were established. Then blood routine, routine coagulation function, clotting factor activity, TEG of each model were tested. 【Results】 The platelet count in the M1 model was 61.00±10.24 (×109/L), and reduced to 28.83±10.36(×109/L) in M2 (P<0.01). The MA value (mm) of two groups detected by TEG was 29.35±2.37 vs 20.53± 2.76 (P<0.01). In M1 and M2 model, The activities of primary clotting factors respectively decreased to about 40% and 30% to original in M1 and M2. The R value of TEG prolonged to (6.32±0.85) min and (7.27±0.63) min respectively, still within the normal range(baseline 4.97±1.04). The fibrinogen concentration in the M1 and M2 model decreased to (1.10±0.08) g/L and (0.81±0.10) g/L(P<0.01), which had the same variation tendency to Alpha angle of TEG (25.65±4.95 vs 16.63±3.94, P>0.05). 【Conclusion】 MTP with blood components supplemented such as platelet and cryoprecipitate in time has effectively improved the Plt and Fib in vitro large-dose blood loss/transfusion model.

ABSTRACT

Objective To explore the effect and mechanism of insulin-like growth factor 2 ( IGF2 ) on the proliferation of human ovarian granulosa cells ( KGN ). Methods KGN cells cultured in vitro and treated with different concentrations of IGF2 were divided into control group and IGF2 group (25 μg/L, 50 μg/L, 100 μg/L), and then cells were divided into control group, 100 μg/L IGF2 group, LY294002 group, and IGF2 +LY294002 group after intervened the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway with LY294002. MTS and 5-ethynyl-2'- deoxyuridine (EdU) method was used to detect the effect of IGF2 on KGN cell proliferation, and enzyme linked immunosorbent assay was used to detect the contents of estrogen and progesterone in cell culture supernatant. The expressions of insulin like growth factor 1 receptor (IGF1R), protein kinase B (Akt), phosphorylated protein kinase B(p-Akt) and CYP19A1 protein in each group were detected by Western blotting. Results With the concentration gradient of IGF2, the proliferation rate of KGN cells and the secretion of estrogen and progesterone gradually increased. The cell proliferation rate and hormone level in the group treated with lOOfig/L IGF2 were the highest (P<0.01), while the PI3K/Akt signaling pathway was inhibited, and the cell proliferation rate and hormone secretion decreased significantly (P<0.01). The protein expression levels of IGF1R, p-Akt and CYP19A1 in different concentration groups increased significantly (P<0.05). While the expression of the above proteins were affected by intervened the PI3K/Akt signaling pathway. Compared with the control group, the protein expression of IGF1R and p-Akt increased significantly in IGF2 group and IGF2 +LY294002 group(P<0.01), CYP19A1 increased significantly in IGF2 group(P<0.01), the protein expression of p-Akt and CYP19A1 decreased significantly in LY294002 group (P<0.05), there was no significant difference in the protein expression of IGF 1R. Compared with the IGF2 group, the protein expression of p-Akt and CYP19A1 decreased in IGF2 +LY294002 group (P<0.01), there was no statistically significant difference in the protein expression of IGF1R, and the expression levels of IGF1R, p-Akt and CYP19A1 were significantly reduced in LY294002 group (P<0.01). Conclusion IGF2 may promote the proliferation and secretion of human ovarian granulosa cells through the PI3K/Akt signaling pathway mediated by IGF1R.

ABSTRACT

Objective:To investigate the antimicrobial resistance characteristics of carbapenem-resistant Enterobacteriaceae (CRE) isolated from outpatients with diarrhea in Shanghai, and provide support for surveillance, prevention and control of CRE. Methods:A total of 800 fecal swabs of the outpatients with diarrhea were collected from 23 sentinel hospitals for diarrhea pathogen surveillance in Shanghai from January 2018 to December 2019. The drug-resistant strains were isolated using MacConkey plates containing 1 μg/μL meropenem. The collected strains were identified preliminarily by the VITEK-2 Compact system and VITEK mass spectrometry. The minimum inhibitory concentration (MIC) of the strain was determined by the broth microdilution method. The multi-locus sequence typing (MLST) method and pulsed-field gel electrophoresis (PFGE) were used to analyze the homology of drug-resistant strains. The transferability of the resistance gene was investigated by a junction experiment. High-throughput sequencing was used to characterize the isolates. Results:Seven non-repetitive CRE isolates were multi-drug resistant carbapenem-resistant Escherichia coli (CREC) strains that produce New Delhi metallo-β-lactamase (NDM) with resistance to several commonly used antibiotics in clinical therapy. The molecular typing results showed that the CRE strains had different sequence types, and diverse PFGE patterns. The stains were all positive for blaNDM genes, including blaNDM-5 and blaNDM-13, with blaNDM-5 as the main type. The carbapenem-resistant genes could be transferred to EC600 by conjugation. Conclusion:The intestinal carbapenem-resistant strains in this study are all NDM-producing Escherichia coli. The isolates carried blaNDM and other resistance genes. The MLST analysis showed that they belonged to different cloning types. Antimicrobial resistance genes could be horizontally transferred to EC600 by conjugation.

ABSTRACT

Objective@#To understand the seasonality and etiological characteristics of infectious diarrhea in adults from Shanghai.@*Methods@#Adult patients with diarrhea who had visited the enteric disease clinics in 22 hospitals that carrying on the Diarrhea Comprehensive Surveillance sentinel programs in Shanghai during 2014-2017, were surveyed. Stool specimens were collected according to the different intervals of sampling and detected for 12 bacteria and 5 viruses. Concentration ratio and circular distribution method were used for data analysis.@*Results@#From 2014 to 2017, a total of 9 573 stool specimens were collected from the targeted diarrhea patients ≥18 years old (n=96 067), through the Shanghai Diarrhea Comprehensive Surveillance program. The positive rate of detection was 46.44%. Seasonal peaks of infectious diarrhea were both seen in summer (bacteria peak, diarrheagenic Escherichia coli and Vibrio parahaemolyticus, etc.) and in winter (virus peak, Norovirus, etc.). Both bacterial and viral infections presented seasonal concentration (Raleigh’s test P<0.001) but more obvious with bacterial infection. Viral infection accounted for 60.19% of the cause of infectious diarrhea. The top five predominant pathogens appeared as Norovirus, Rotavirus, diarrheagenic Escherichia coli, Vibrio parahaemolyticus, and Salmonella spp..@*Conclusions@#Among the adult outpatients with infectious diarrhea in Shanghai, obvious seasonality was seen, with peaks in both summer and winter. Viral infection with Norovirus in particular, appeared as the predominant source of infection. Active, continuous and comprehensive diarrhea-related surveillance programs would be able to monitor the changing dynamic of pathogen spectrum, and lead to the adoption of targeted preventive measures.

ABSTRACT

Objective The level of lactic acid in blood can reflect the degree of ischemia and hypoxia of brain tissue and cerebral perfusion pressure. The aim of this paper is to explore the value of blood lactate and lactate clearance in evaluating the survival rate and neurological outcome of patients with craniocerebral trauma. Methods The clinical data of 497 craniocerebral trauma patients admitted to our hospital from September 2017 to July 2018 were collected and retrospectively analyzed. Patients were divided into groups with different 6 h lactate clearance rates and admission lactate levels, and the differences in mortality and outcome of neurological function in each group were compared. Results The serum admission lactate levels、serum lactate levels at 6 hours, 28-day mortality and 28-day poor nerve function prognosis rate of patients with different 6h lactate clearance rates were statistically significant differences(P < 0. 05). The efficacy of 6h lactic acid to predict the mortality rate of patients was better than that of admission lactic acid and 6h lactate clearance rate (Z=3.71、Z=3.95,P<0.05). However, in predicting the neurological function of patients, the lactate clearance rate is not better than blood lactate level at any time(Z=1.30,Z=0.81,P>0.05). Conclusion 6h lactic acid has the best ability to judge the mortality of patients while lactic acid clearance rate is not better than the blood lactate level at any time in predicting the neurological function of patients.

ABSTRACT

@#The facial nerve is the longest nerve shaped the bone tube, which has many turnings and narrow path. About 7% to 10% of patients with temporal bone fracture have facial paralysis. Most of the patients showed loss of frontal lines, inability to close eyes, and deflection of the teeth. Facial nerve decompression has been an effective way to relieve the symptoms and restore facial nerve functions. However, the issue of surgical indications, timing of surgery, and scope of decompression still need further research.

ABSTRACT

A family of transcription factors known as Id proteins, or inhibitor of DNA binding and differentiation, is capable of regulating cell proliferation, survival and differentiation, and is often upregulated in multiple types of tumors. Due to their ability to promote self-renewal, Id proteins have been considered as oncogenes, and potential therapeutic targets in cancer models. On the contrary, certain Id proteins are reported to act as tumor suppressors in the development of Burkitt's lymphoma in humans, and hepatosplenic and innate-like T cell lymphomas in mice. The contexts and mechanisms by which Id proteins can serve in such contradictory roles to determine tumor outcomes are still not well understood. In this review, we explore the roles of Id proteins in lymphocyte development and tumorigenesis, particularly with respect to inhibition of their canonical DNA binding partners known as E proteins. Transcriptional regulation by E proteins, and their antagonism by Id proteins, act as gatekeepers to ensure appropriate lymphocyte development at key checkpoints. We re-examine the derailment of these regulatory mechanisms in lymphocytes that facilitate tumor development. These mechanistic insights can allow better appreciation of the context-dependent roles of Id proteins in cancers and improve considerations for therapy.

ABSTRACT

Plasma exchange (PE) is a therapeutic blood component replacement method. The blood of patients is first separated into plasma and blood cell components using a blood cell separator in vitro, the plasma containing harmful pathogenic substances is then discarded and replaced with the same volume of exchange solution. Finally the separated blood cells together with the exchange solution are returned back to the blood circulation of patients. By reducing the circulating antibodies, abnormal plasma proteins or cytokines and other pathogenic molecules, PE can block the disease process. PE has a good therapeutic effect on neuromyelitis optica-related optic neuritis (NMO-ON), which shows resistant to glucocorticoid therapy for the first onset. The American Society for Apheresis guideline evaluates PE for acute optic neuritis as a recommended grade 1B, type II indication. In the implementation of PE treatment for NMO-ON and other diseases, indications and contraindications should be strictly adhered to the guideline, treatment procedures and protocols should be optimized, common adverse events and its prevention and management should be known and alerted. It is important to conduct multi-center clinical cooperation and a high standard clinical randomized controlled study, to find out the optimal time window, the best protocol, and the associated factors for the efficacy and prognosis of PE in NMO-ON.

ABSTRACT

Objective@#To analyze the pathogen spectrum and epidemiological characters of infectious diarrhea cases in Shanghai from July 2013 to June 2015.@*Methods@#From July 2013 to June 2015, using multi-stage sampling to select 22 hospitals as adult diarrhea surveillance sentinels, and 3 district central hospitals together with Shanghai municipal children's hospital as children diarrhea surveillance sentinels. A total of 6 267 diarrhea cases were sampled. The demographic characters, main clinical manifestations and signs of cases were investigated, and stool specimens were collected to conduct the bacteria culture and virus nucleic acid detection. The difference of positive rate of bacteria and virus in different seasons, and age difference of relevant pathogens were compared.@*Results@#Among 6 267 cases, 3 262 (52.05%) were male, and most of them were in 50-69 years group (1 999 cases, 31.90%) and 30-49 years group (1 691 cases, 26.98%). Totally, 2 783 positive specimens were detected out of 6 267 specimens with the positive rate being 44.41%. A total of 7 kinds of bacteria and 5 kinds of viruses were detected. The positive rate for bacterium was 12.61%(790 cases), mainly being vibrio parahaemolyticus (256 cases), diarrheagenic E.coli (239 cases) and salmonella (209 cases). The positive rate for virus was 31.80% (1 993 cases), mainly being norovirus (1 172 cases) and rotavirus (546 cases). The positive rates of viruses in winter of 2013 and 2014 were 57.89%(429 cases) and 62.14%(522 cases) respectively, higher than those of bacterium in the same periods which were 2.43% (18 cases) and 2.86% (24 cases) respectively. The positive rates of bacterium in summer of 2013, 2014 and 2015 were 14.56% (97 cases), 25.29%(258 cases) and 21.21% (49 cases), also higher than those of viruses in the same periods which were 7.51% (50 cases), 8.43%(86 cases) and 11.69% (27 cases) respectively, all of the above differences were statistically significant (P<0.05). The cases of 50-69 years group had the highest positive rate of pathogen, which was 47.57% (951/1 999). Secondly was those of 30-49 years group with 47.13% (797/1 691). Positive rate of pathogen for cases of 0-2 years group was 35.74% (213/596).@*Conclusion@#The pathogen spectrumes of infectious diarrhea in Shanghai are mainly vibrio parahaemolyticus, diarrheagenic E.coli, salmonella, norovirus and rotavirus. The summer and winter season peak was obvious. Specific etiological surveillance and control strategies should be strengthened aiming at focus groups including children and the elderly in different seasons.
