Identification of novel mammalian viruses in tree shrews(Tupaia belangeri chinensis)

The Chinese tree shrew(Tupaia belangeri chinensis),a member of the mammalian order Scandentia,exhibits considerable similarities with primates,including humans,in aspects of its nervous,immune,and metabolic systems.These similarities have established the tree shrew as a promising experimental model for biomedical research on cancer,infectious diseases,metabolic disorders,and mental health conditions.Herein,we used metatranscriptomic sequencing to analyze plasma,as well as oral and anal swab samples,from 105 healthy asymptomatic tree shrews to identify the presence of potential zoonotic viruses.In total,eight mammalian viruses with complete genomes were identified,belonging to six viral families,including Flaviviridae,Hepeviridae,Parvovirinae,Picornaviridae,Sedoreoviridae,and Spinareoviridae.Notably,the presence of rotavirus was recorded in tree shrews for the first time.Three viruses-hepacivirus 1,parvovirus,and picornavirus-exhibited low genetic similarity(<70%)with previously reported viruses at the whole-genome scale,indicating novelty.Conversely,three other viruses-hepacivirus 2,hepatovirus A and hepevirus-exhibited high similarity(>94%)to known viral strains.Phylogenetic analyses also revealed that the rotavirus and mammalian orthoreovirus identified in this study may be novel reassortants.These findings provide insights into the diverse viral spectrum present in captive Chinese tree shrews,highlighting the necessity for further research into their potential for crossspecies transmission.

Evaluating patients' perception of service quality at hospitals in nine Chinese cities by use of the ServQual scale

Objective: To investigate patients' perception of service quality at hospitals in nine Chinese cities and propose some measures for improvement. Methods: The ServQ ual scale method was used in a survey involving patients at out-patient and in-patient facilities in Shanghai, Chongqing, Chengdu, Nanning, Guilin and Laibin of Guangxi, Honghezhou of Yunnan, Wulumuqi of Xinjiang and Zhongshan of Guangdong. The data collected were entered and analyzed using SPSS 20.0. Statistical analyses included descriptive statistics, factor analyses, reliability analyses, product-moment correlations, independent-sample t-tests, One-way ANOVA and regression analyses. Results: The Kaiser-Meyer-Olkin value for the factor analysis of the scale was 0.979. The Cronbach's α for the reliability analysis was 0.978. All the Pearson correlation coei cients were positive and statistically signii cant. Visitors to out-patient facilities reported more positive perception tacilities on tangibles(t = 4.168, P(t = 1.979, P <han visitors to in-patient f 0.05).

Hospitals in various regions of China should enhance their awareness and ability to serve their patients.

Role of perioperative parenteral nutrition in severely malnourished patients with Crohn's disease

AIM： To evaluate the effect of perioperative parenteral nutrition on serum immunoglobulin, weight change, and post-operative outcome in severely malnourished patients with Crohn＇s disease. METHODS： Thirty-two severely malnourished patients with Crohn＇s disease who had undergone surgery in our hospital were reviewed. Sixteen patients who received perioperative parenteral nutrition were enrolled in the study group, and the other 16 patients who did not receive parenteral nutrition were enrolled in the control group. Serum immunoglobulin, body mass index （BMI）, liver function, weight change, and postoperative complications were evaluated. RESULTS： Serum IgM levels elevated 1 wk before surgery in both groups, and decreased to normal value （from 139±41 to 105±29 mg/dL, P = 0.04） 4 wk after operation in the study group, while no significant changes was noted in the control group （from 133±16 to 129±13 mg/dL, P = 0.34）. There were no significant changes in concentrations of IgG and IgA. The BMI of the study group increased from 13.9±0.6 to 15.3±0.7 kg/m^2 （P = 0.02） with no significant change in the control group （14.1±0.7 and 14.5±0.5, respectively, P = 0.81）. The percentage of resuming work was higher in the study group than in the control group. CONCLUSION： Perioperative parenteral nutrition possibly ameliorates the humoral immunity, reverses malnutrition, and facilitates rehabilitation. 2005 The WJG Press and Elsevier Inc.

Research on the Application of Diversified Teaching in Gynecological Clinical Teaching

At present,the main body of clinical teaching in obstetrics and gynecology is still the traditional clinical teaching method,in which clinical teachers are the main body,and interns are the passive.It is not conducive to giving full play to interns'learning enthusiasm and ability to actively solve problems if lack of stimulating the clinical thinking and cultivating the ability to raise questions.In the face of the problems and deficiencies in gynecological clinical teaching in the new era,our team tries to adopt diversified teaching methods,such as medical record teaching method,multimedia teaching method,main-role teaching method,problem-based learning teaching method and so on,so as to improve students'ability of autonomous learning and problem-solving,as well as students'ability of innovation and cooperation.Therefore,clinical teaching teachers and teaching managers should keep pace with the times to carry out diversified teaching mode reform in gynecological clinical teaching.

The possible role of interleukin-6 (IL-6) and survivin in the pathogenesis of embryonic damage

Objective:To investigate the role of interleukin-6(IL-6)and survivin in the pathogenesis of embryonic damage and to provide theoretical basis for the diagnosis and treatment of embryonic arrest.Methods:A total of 50 patients with embryo arrest for unknown reasons in People's Hospital of Changle County,Shandong Province were selected as the embryo termination group,and 50 patients with normal pregnancy were selected as the normal pregnancy group.Serum and chorionic tissue of each group were collected,and the serum IL-6 concentration of the subjects in both groups was determined by enzymatic linked immunosorbency assay.The mRNA expression levels of interleukin 6 and survivin in villus were determined by real-time quantitative PCR.The expression and distribution of interleukin 6 and survivin in villi were detected by SP immunohistochemical method.Results:The mRNA and protein levels of survivin in embryo suspension group were significantly lower than those in normal pregnancy group.Conclusion:The normal expression of interleukin-6 and survivin in the early pregnancy villus tissue is very important to maintain the normal development of early embryo.

Studies on the correlation between human papilloma virus vaccine and premature ovarian failure

Cervical cancer is the most common malignant tumour of the female reproductive system,resulting in more than 500,000 new cases annually worldwide.In developing countries,cervical cancer ranks second in terms of cancer mortality among women.Human papilloma virus is the primary causative agent of cervical cancer,with approximately 70 percent of cervical cancers caused by high-risk types of human papilloma virus 16 and 18.There are currently three types of human papilloma virus vaccines available:bivalent,quadri-valent and nine-valent.However,in recent years,it is reported that cervical cancer vaccine can cause premature ovarian failure.Consequently,an extensive literature search to find out the correlation between human papilloma virus vaccine and premature ovarian failure became a priority.There is no sufficient evidence to support or prove that there is a link between the human papilloma virus vaccine and premature ovarian failure.Hence,the vaccine does not cause premature ovarian failure.

Expression and molecular mechanism of PCNA,Caspase-3,IL-6 and Survivin proteins in chorionic villi and decidual tissue of early embryo damage

Objective:This study aims to explore its role in embryo damage and the relationship between them by testing the expression of PCNA,Caspase-3,IL-6 and Survivin protein in the chorionic villi and decidual tissue of patients with unexplained early embryo damage and normal early pregnancy at the same time voluntarily requested uterine aspiration abortion in order to clarify the pathogenesis of early embryo damage from the cellular and molecular perspectives,and provide theoretical basis for the diagnosis and treatment of embryo damage.Methods:From July 2018 to July 2019,30 patients with unexplained embryo damage were selected as embryo damage group,thirty normal early pregnancy patients with aspiration abortion were selected as the normal early pregnancy group.The decidual tissue and chorionic villi of the two groups were collected to observe the structural and pathological changes.Immunohistochemical method was used to detect the distribution of PCNA,Caspase-3,IL-6 and Survivin in the chorionic villi and decidual tissue,as well as the expression changes of the above four proteins.Results:Compared with the normal early pregnancy group,the chorionic villi in the early embryo damage group were obviously dysplasia,degenerative changes,structural disorders,homogeneous destruction,obvious reduction or even disappearance of trophoblast cells,inflammatory cell infiltration,more neutrophils and lymphocytes,interstitial edema and cell atrophy,accompanied by hemorrhage;The decidual tissue of the intima was not good,most of the cells were spindle-shaped,the structure was disordered,the stroma has edema,inflammatory cells can be seen,and hemorrhage existed.The results of immunohistochemistry showed that the expression of PCNA protein in chorionic villi and decidual tissue of early embryo damage group decreased significantly(P<0.05),while the expression of Caspase-3 protein increased significantly(P<0.05).The expression of IL-6 protein decreased significantly(P<0.05),and the expression of Survivin protein decreased significantly(P<0.05).Conclusion:During early pregnancy,due to the down-regulation of the expression of proliferating cell nuclear antigen PCNA and apoptosis inhibitor protein Survivin in chorionic and decidual tissues,the balance between proliferation and apoptosis is broken,which has an increase in Caspase-3 expression and a decrease in IL-6 expression.It may be that the balance of Th1/Th2 in chorionic and decidual tissues inclines to Th1,which leads to excessive apoptosis of chorionic and decidual tissues and the cessation of early embryo damage.
