1.In vitro diagnosis of infectious diarrhea in children: from microscopic examination to metagenomic era
Chinese Journal of Laboratory Medicine 2021;44(4):271-273
Intestinal infection is one of the most common infectious diseases in children in China, and the intestinal infection is often featured as the diarrhea the main clinical symptom. Systematically understanding the etiological characteristics of intestinal infection in children in China and efficiently detecting the pathogens are crucial on the early treatment and prevention of diseases. The detection technology of clinical pathogenic microorganisms in China is undergoing a revolutionary era from microscopic examination to metagenomic sequencing.

Objective To investigate relationship between microRNA-200c and ZEB1 in cervical epithelial mesenchymal transition factor. Methods 50 cases diagnosed with cervical cancer whose tumor tissue were taken to be the experiment group.50 cases diagnosed with uterine myoma whose normal tissue were taken to be the control group.ZEB1 and microRNA-200c of uterine tissue were were detected.Results The average level of ZEB1 in the experimental group was significantly higher than that of the control group (P<0.05), and in cervical cancer, lymph node metastasis and the depth of myometrial invasion had statistically significant (P<0.05).In experimental group, microRNA-200c average was lower than control group (P<0.05), and in cervical cancer, different pathological grade group, lymph node metastasis and deep muscular layer infiltration had statistically significant(P<0.05).In experimental group, ZEB1 and microRNA-200c showed negative correlation(r =-0.270 P =0.001).Conclusion The expression level of ZEB1 in cervical cancer is higher, and the expression level of microRNA-200c in cervical cancer is lower, suggesting that the two factors may play an important role in the invasion and metastasis of cervical cancer.The correlation between the two factors suggests that microRNA-200c may be involved in the process of cervical cancer by ZEB1.

Papers information such as document type, found support, author affiliation type, and discipline classification, etc. was analyzed.
RESULTSSeven hundred and forty two papers including 27 full English articles in total were published in Chinese Journal of Applied Physiology from 2009 to 2013. More papers were supported by national, provincial, and the other foundation, it was about 82.6% of all papers.
CONCLUSIONChinese Journal of Applied Physiology has stable manuscript resources, various discipline papers, and play an important role for development of applied physiology in China.

Objective To explore the protective effect of atorvastatin on irradiated endothelium and the thrombomodulin(TM)expression.Methods Cultured human coronary artery endothelial cells(HCAEC)and human umbilical vein endothelial cells(HUVEC)were treated by atorvastatin at the final concentration of 10 μmol/ml for 10 min,and then irradiated with 2 and 25 Gy.Cell cycles status and TM expression were quantitatively measured by flow cytometry 24 hours after irradiation.Protein C activation in endothelial cells was also assessod.Results After administration with atorvastatin for 24 h,the TM expression increased by 77%,59% and 61% in normal control group,2 Gy group and 25 Gy group,respectively(t=27.395,26.420,58.065;P=0.000).The protein C levels decreased by 23% and 34% compared with the normal group post-irradiation to 2 and 25 Gy,but increased by 79% and 76% compared with the irradiated control group after administration with atorvastatin.The rates of cell apoptosis decreased by 6% and 16% in 2 Gy and 25 Gy groups,respectively after administration with atorvastatin for 24 h(t=4.178,17.863;P=0.000).Conclusions Atorva statin can protect endothelia cell from irradiation-induced apeptosis by increasing TM expression and protein C activation.

Objective To explore the integrity of white matter changes in patients with vascular mild cognitive impairment (VaMCI)based Leukoaraiosis.Methods The patients which appeared white matter hyperintensities in subcortical were performed psychological testing,then 48 VaMCI patients and 18 without cognitive impairment volunteers(NC)were choosed and performed DTI scanning,to determine the white matter’s values of FA and ADC in the following bilaterally symmetrical regions of interest(ROI):entorhinal cortex lobe,hippocampal vault,anterior of corpus callosum,posterior of corpus callosum,inferior frontal lobe,superior temporal lobe and angular gyrus of occipital lobe. Then the differences of the data of DTI between two groups and the relevance between neuropsychological score and DTI’s data were analysed.Results ADC values were significantly higher of VaMCI group in the left inferior frontal lobe,left anterior of corpus callo-sum,left hippocampus vault and right angular gyrus compared with NC group(P <0.05),and in the left hippocampus ADC values and MoCA scores was negatively correlated(r=-0.34,P =0.02).There was no significant difference of FA values between groups. Conclusion The ADC values in many cognitive related areas was reduced in VaMCI patients.

Objective To evaluate efficacy of routine cleaning and disinfection methods for incubators,and put forward a feasible improvement solution.Methods 30 incubators used in a neonatal intensive care unit of a hospital between Decem-ber 2013 and June 2014 were chosen and randomly divided into baseline,control,and trial groups(10 incubators in each group).Baseline group and control group were disinfected by routing disinfection method (wiping internal and external sur-faces of incubators with water and chlorine-containing disinfectant),trial group adopted intensified disinfection method (wi-ping internal surfaces of incubators with alcohol)on the basis of routine disinfection,disinfectant efficacy of three groups were compared.Results In baseline group,unqualified incubators were initially detected on the fourth day of monitoring, all incubators were contaminated in varying degrees on the seventh day of monitoring,the detection rate of unqualified spec-imens was 31.43% (88/280).The median time for the initial detection of unqualified incubators in control group and trial group were on the fifth day and seventh day respectively,there was significant difference between two groups(χ2 =12.38, P <0.05);The unqualified rate of trial group was significantly lower than control group (15.36%[43/280]vs 32.86%[92/280],χ2 =23.43,P <0.05 ).Conclusion Intensified disinfection with alcohol on the basis of routine disinfection method can effectively improve the disinfectant efficacy of the surface of incubators,it is convenient,inexpensive and safe, and worth to be popularized in primary hospitals.

Objective Following the prognosis of patients with myasthenia gravis(MG) who received both immunosuppressants and thymectomy, to determine whether the sequence and timing of treatment have influences on outcomes of MG and also to select significant predictors of prognosis.Methods It was a retrospective study which reviewed 105 patients with MG who underwent thymectomy and immunosuppressants between Januay, 2000 and December, 2013.All patients were divided into two subgroups based on their order of treatment.Thirty two patients were called as immunosuppressants-first group, and 73 patients were called as thymectomy-first group.The ratios of ideal status of two groups were compared with use of the ChiSquare test.Predictors of ideal status were analyzed by logistic regression.Results (1) After 1 year, 2 years and 5 years of intervention, the proportion of ideal status was significantly higher in the thymectomy-first group than that in the immunosuppressants-first group[(33%-50%) vs.(10%-20%), P <0.05].For oMG patients, after 1 year, 2 years and 5 years of treatment, thymectomy-first group had a higher ideal status rates than immunosuppressants-first group[(25%-50%) vs.(11%-18%)].But no significant difference was noted in the rates of ideal status at each follow-up time point.(2)Multivariate logistic regression analysis showed that sequence of treatment (OR =0.154, 95 % CI: 0.046-0.518, P =0.002) and symptom-thymectomy interval(OR =0.903,95 % CI: 0.835-0.976, P =0.010) were the significant predictors of ideal status.Conclusion Thymectomy prior to immunosuppressants is associated with relatively good prognosis.It is suggested that patients with gMG, or adult patients with oMG who are resistant to drug, will be better to undergo thymecotomy as early as possible.
