Objective To understand the distribution and changing resistance profiles of clinical isolates of Enterococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Enterococcus according to the unified protocol of CHINET program by automated systems,Kirby-Bauer method,or E-test strip.The results were interpreted according to the Clinical & Laboratory Standards Institute(CLSI)breakpoints in 2021.WHONET 5.6 software was used for statistical analysis.Results A total of 124 565 strains of Enterococcus were isolated during the 7-year period,mainly including Enterococcus faecalis(50.7％)and Enterococcus faecalis(41.5％).The strains were mainly isolated from urinary tract specimens(46.9％±2.6％),and primarily from the patients in the department of internal medicine,surgery and ICU.E.faecium and E.faecalis strains showed low level resistance rate to vancomycin,teicoplanin and linezolid(≤3.6％).The prevalence of vancomycin-resistant E.faecalis and E.faecium was 0.1％and 1.3％,respectively.The prevalence of linezolid-resistant E.faecalis increased from 0.7％in 2015 to 3.4％in 2021,while the prevalence of linezolid-resistant E.faecium was 0.3％.Conclusions The clinical isolates of Enterococcus were still highly susceptible to vancomycin,teicoplanin,and linezolid,evidenced by a low resistance rate.However,the prevalence of linezolid-resistant E.faecalis was increasing during the 7-year period.It is necessary to strengthen antimicrobial resistance surveillance to effectively identify the emergence of antibiotic-resistant bacteria and curb the spread of resistant pathogens.

OBJECTIVE: To understand the true perception and attitude of the healthcare workers(HCWs) on the workplace violence(WPV) in a secondary Grade A hospital.METHODS: A total of 27 HCWs in a secondary Grade A hospital were selected as study subjects using a typical sampling method. Semi-structured interviews were conducted to collect the information of their perception and attitude on the types and effects of WPV, as well as on the coping measures and the work stress. The characteristics of WPV in the hospital were analyzed. RESULTS: The interviewees believed that verbal abuse was the most common type of WPV received by HCWs. Nurses and female workers were the main victims of WPV. Horizontal violence among colleagues and sexual harassment should not be ignored. Common causes of violent incidents for patients and their family members against HCWs included the fees for treatment, doctor-patient communication, patients alcohol abuse and treatment outcomes not meeting patients′ expectation. About half of the interviewees said that WPV had serious impact on their mental health. The follow-up coping measures to violent incidents were mostly to reassurance to patients with unconditional apology from the HCWs. More than half of the interviewees considered that they had acceptable workload, while some interviewees considered their work to be stressful. The interviewees suggested that improving doctor-patient communication, hospital systems, and the professional knowledge of HCWs were the recommended means to prevents and control the WPV. CONCLUSION: The perception and attitude of HCWs on WPV in this hospital are relatively scattered. Considering the complex causes, the serious consequences, and difficult coping measures, the hospitals, HCWs and all sectors of society need to take comprehensive measures to prevent WPV towards HCWs.

Objective To evaluate the association between blood test parameters and intensity of Plasmodium falciparum infections among imported falciparum malaria cases in Tianjin City from 2015 to 2019, so as to provide insights into the early diagnosis of imported P. falciparum malaria. Methods The epidemiological data of 37 imported cases with confirmed diagnosis of P. falciparum malaria in Tianjin City from 2015 to 2019 were collected, and the epidemiological features and clinical manifestations were retrospectively analyzed. In addition, the association between blood test parameters and intensity of P. falciparum infections was evaluated among the imported P. falciparum malaria cases. Results Among the 31 imported P. falciparum malaria cases, there were 31 cases (83.8%) with a reduction in platelet (PLT) counts, 16 cases (43.2%) with a reduction in red blood cell (RBC) counts, 16 cases (43.2%) with a reduction in hemoglobin (Hb) concentrations, 23 cases (62.2%) with a rise in neutrophil percentage (NEUT%), 32 cases (86.5%) with a rise in total bilirubin (TBIL) concentrations, 29 cases (78.4%) with a rise in alanine aminotransferase (ALT) concentrations, 28 cases (75.7%) with a rise in aspartate transaminase (AST) concentrations, and 23 cases (62.2%) with a rise in gamma-glutamyl transpetidase (GGT) concentrations. The PLT count and Hb concentration correlated negatively with the intensity of P. falciparum infections (Goodman-Kruskal γ = –0.568 and –0.521, both P values < 0.05) and the TBIL concentration and NEUT% correlated positively with the intensity of P. falciparum infections (Goodman-Kruskal γ = 0.496 and 0.610, both P values < 0.05) among imported falciparum malaria cases; however, there were no associations of ALT, AST, GGT levels or RBC count with the intensity of P. falciparum infections among the imported falciparum malaria cases (Goodman-Kruskal γ = 0.370, 0.497, 0.314 and –0.434, all P values > 0.05). Conclusions PLT, Hb, TBIL and NEUT% may serve as markers for early auxiliary diagnosis of imported P. falciparum malaria, and PLT and TBIL may provide valuable information for the diagnosis of severe imported P. falciparum malaria.

Objective • To explore the clinical characteristics of the obsessive-compulsive disorder (OCD) patients with hoarding symptoms and analyze the risk factors related to hoarding symptoms. Methods • A total of 247 OCD patients and 137 healthy controls (HC) were enrolled. The OCD patients were divided into hoarding group and non-hoarding group according to hoarding symptoms. Yale-Brown Obsessive-Compulsive Scale, Hamilton Depression Scale, Hamilton Anxiety Scale, Neuroticism Extraversion Openness Five-Factor Inventory and Obsessive Belief Questionnaire-44 were used to measure the severity of OCD, levels of depression and anxiety, personality characteristics and obsessive-compulsive beliefs of the three groups. The differences among the groups were compared, and Logistic regression was used to analyze the related factors of hoarding symptoms. Results • Regardless of hoarding symptoms, the scores of depression, anxiety, neuroticism and obsessive beliefs in the patients with OCD were significantly higher than those in the healthy controls (all P=0.000). Compared with OCD/non-hoarding group, OCD/hoarding group had a significantly lower level of extroversion (P=0.000), a significantly higher level of perfectionism/certainty (P=0.037), and higher scores in indecisiveness (P=0.003), pathological responsibility (P=0.006) and pathological slowness (P=0.000). There was statistical significance in age (OR=0.94), extraversion score (OR=0.89) and pathological retardation score (OR=2.50) in Logistic regression model (all P<0.05). Conclusion • The risk of hoarding symptoms in the OCD patients decreases with the increase of age and extroversion level, and increases with the increase of pathological retardation level.

Objective To investigate the epidemiological characteristics of malaria and implementation of the “1-3-7” approach in malaria elimination in Yunnan Province, so as to provide the data support for the development of post-elimination surveillance interventions. Methods All data pertaining to malaria cases in Yunnan Province from 2014 to 2019 were captured from the Notifiable Disease Reporting System of Chinese Center for Disease Control and Prevention, and the changes in the epidemic situation of malaria were analyzed during the 5-year period. In addition, the core indexes regarding the “1-3-7” approach in malaria elimination of Yunnan Province from 2014 to 2019 were retrieved from the Malaria Control System in the Parasitic Disease Information Reporting System, and all changes in the indexes were descriptively analyzed. Results During the period from 2014 to 2019, a total of 2 283 malaria cases were reported in Yunnan Province, including 1 927 cases with vivax malaria, 326 cases with plasmodium malaria, 29 cases with other species of malaria, and one case with unidentified species. There were 64 local cases, 2 219 overseas imported cases. Among the 2 283 malaria cases, the male/female ratio was 4.58∶1, and 80.25% of the cases were aged from 15 to 50 years. Farmer (70.00%) was the predominant occupation, and 76.70% (1 751/2 283) of the cases were identified in 25 border counties (districts). Malaria cases were reported in each month during the 5-year period, and the number of malaria cases increased from April, peaked on May to July, and started to decline on August. From 2014 to 2019, the reporting rate of malaria cases within 24 hours upon diagnosis was 100%, and the detection of malaria cases was 99.69% (2 276/ 2 283) in the laboratory, with a 99.65% (2 275/2 283) rate of definite diagnosis. In addition, the percentage of individual epidemiological investigations within 3 days was 100.00% (2 283/2 283), and the number of epidemic foci survey and treatment within 7 days was 576 during the 3-year period from 2017 to 2019. The goal of malaria elimination was achieved in Yunnan Province on June, 2020. Conclusions Malaria has been eliminated in Yunnan Province, and management of overseas imported malaria is the primary challenge to consolidate the malaria elimination achievements in the future. However, the approach in malaria elimination remains to be maintained, and the role of the Yunnan Provincial Malaria Diagnostic Reference Laboratory requires to be strengthened.

Gut microbiota is closely related to human health, and its composition can give us health information. The large-scale population sampling is required on gut microbiome research; however, fresh feces samples are not easy to obtain, and rapid low-temperature freezing is difficult to achieve. With the development of technology, preservation solutions are widely used for sample collection, storage, and transport under normal temperature conditions. Preservation solutions can be used in large scale sample collection, wide geographical distribution, diverse on-site sampling conditions, heavy workload, and poor transportation conditions. In this study, five healthy volunteers were recruited. After collecting their fresh stool samples, effect of 5 different commercial preservation solutions was evaluated at room temperature. Samples in different preservation solutions after placing fresh stool samples at the 0, 1, 3, 7, 15, and 30 days were collected. All samples were tested by 16S rRNA V3-V4 high-throughput sequencing to analyze the influence of microbiome composition in different preservation solutions. The results show that different preservation solutions had distinct effects on the gut microbiome composition. Compared with the control, different preservation solutions had little effect on the amount of OUTs; preservation solutions A, B and C were closer to the control in the composition of the gut microbiota, but preservation solution D significantly changed the composition by increasing Actinobacteria and Firmicutes abundance. With the time, all solutions tended to reduce the diversity of the microbiota. Preservation solution E significantly reduced the diversity of the flora; on the 30th day, all five solutions changed the composition; the individual differences in the composition of the gut microbiome were the main factors affecting the similarity of each sample, and were derived from different stools donors. The same samples, no matter which storage solution and storage time, were directly closer to each other. Different storage solutions had different effects on the content of Gram-positive bacilli, Gram-positive cocci and Gram-negative bacteria. Storage solutions C and E reduced the abundance of Bifidobacterium, whereas storage solution D increased; except that preservation solution E relatively reduced the abundance of Lactobacillus, but the preservation solution A, B, C, and D were all closer to the control. Except for the greater difference in preservation solution D, preservation solution C was the closest to the control group on Streptococcus; preservation solution D reduced Ruminococcaceae UCG 003 than the control group. However, other preservation solutions were not much different from the control group; different preservation solutions increased the abundance of Escherichia-Shigella than the control group, and preservation solutions A and B increased the abundance of Klebsiella, but preservation solution C, D, and E were closer to the control group. Overall, preservation solution C performed better in stabilizing the composition of the gut microbiota. This study provides reference for standardized microbiome projects. Subsequent research can choose a targeted preservation solution and preservation time based on this study.

Objctive To investigate the protective effect of resveratrol on oxidative stress damage of follicular granulosa cells induced by hydrogen peroxide. Methods Granulosa cells were collected from the follicular fluid of in vitro fertilization(IVF) patients after oocyte retrieval and cultured. The cultured granulosa cells were divided into four groups: control group, injury model group, 10 μmol / L resveratrol group and 50 μmol / L resveratrol group. Cell viability was determined by CCK-8 assay, malondialdehyde(MDA) content by thiobarbituric(TBA) assay, superoxide dismutase(SOD) level by water soluble tetrazdium-1(WST-1) assay, apoptosis by AnnexinV-FITC / PI double-staining flow cytometry, Bcl-2 and Caspase-3 protein expression by Western blotting, and progesterone secretion by competitive ELISA. Resutls Compared with the control group, the cell viability, SOD level, Bcl-2 protein expression and progesterone secretion were significantly decreased in the injury model group, while MDA content, apoptosis rate and Caspase-3 apoptotic protein expression were significantly increased (P<0. 05) . Compared with the injury model group, the 10 μmol / L resveratrol group showed no statistically significant differences in various parameters; however, the cell viability, SOD level, progesterone secretion, and Bcl-2 and silent information regulator factor 2 related enzyme 1(SIRT1) protein expression were significantly increased, and the MDA content, apoptosis rate, and Caspase-3 apoptotic protein expression were significantly decreased in the 50 μmol / L resveratrol group (P < 0. 05) . Conclusion 50 μmol / L resveratrol can increase the activity of SIRT1, enhance the anti-oxidation and anti-apoptosis ability of granulosa cells and improve the function of granulosa cells.
