Objective To explore the expression of Bcl-6 mRNA in the Tfh cells of HIV/AIDS patients and the relationship between Bcl-6 mRNA and the progression of HIV/AIDS.Methods This experiment chose 60 patients who were confirmed by HIV antibody test positive,during May 2014 to November from AIDS Research Institute in the First Affiliated Hospi-tal,Henan College of Traditional Chinese Medicine.According to the amount of CD4+T cells,the patients with HIV/AIDS were divided into A(CD4<200 cells/μl),B(200 cells/μl500 cells/μl)three groups.The Tfh cells expressed CD4+ CXCR5 + ICOS+ and lymphocyte subpopulation including T,B and NK cells were detected by flow cytometry (FCM).The expression of Bcl-6 mRNA levels were detected by reverse transcription-polymerase chain reaction (RT-PCR).The association between Tfh cells and Bcl-6 mRNA,B cells were analyzed.Results The expression of Bcl-6 mRNA from patients of A,B and C three groups was increased than in healthy individuals (2.94±0.91,2.27±0.62,2.15± 0.351,P <0.05).The percent of Tfh cells from group A patients was higher than group C patients (5.88±3.01 vs 1.26± 0.87,P =0.032)and also the healthy control group (5.88±3.01 vs 0.78±0.42,P =0.004).The percentage of NK cells and B cells in HIV/AIDS patients was no statistically significant.Correlation analysis showed that there was positive corre-lation between the proportion of Tfh cells and Bcl-6 mRNA (r=0.799,P =0.000).And Tfh cells were observed no relation-ship with B cells (r=-0.083,P =0.657).Conclusion The changes of Bcl-6 mRNA and Tfh cells may be related to the progression of HIV/AIDS.

Objective To investigate the effects of electroacupuncture (EA) on the implementation of blind nasojejunal (NJ) tube placement and enteral nutrition (EN) in neurosurgical severe coma patients in intensive care unit (ICU).Methods Seventy-nine neurosurgical severe coma patients admitted to ICU were randomly divided into conventional group (blind NJ tube placement,n =40) and EA group (NJ placement and EA,n =39).EA was performed after NJ tube placement at bilateral acupoints Zusanli (ST36) and Hegu (L14) points using EA treatment instrument.The impelling distance of NJ tube were measured and the success rate of NJ tube placement were calculated.The postoperative complications were observed.Results The difference of NJ tube impelling distances at the 24th,48th,and 72th hours after surgery in EA group were significant longer than that in conventional group (P ＜ 0.05).The success rates of NJ tube placement at the 24th and 72nd hours after surgery in EA group were significantly better than that in conventional group (P ＜ 0.05).Their EN calories qualifiedness rate in 72 hours also increased significantly compared with conventional group and the proportion of patients assisted with parenteral nutrition decreased (P ＜0.05).The postoperative complications including alimentary tract hemorrhage,vomiting,and abdominal distension decreased remarkably in EA group compared with conventional group (P ＜ 0.05).Conclusions EA stimulation at acupoints could promote the gastrointestinal peristalsis of neurosurgical severe coma patients and elevate the success rate of blind NJ tube placement,so it is beneficial for the implementation of early enteral nutrition (EEN).

Objective To investigate the role of bacterial flagellin and CD98 in ulcerative colitis (UC).Methods A total of 60 first episode patients with active UC were recruited,including 30 mild and 30 moderate to severe UC cases.The serum of 30 healthy volunteers and normal intestinal tissues surgically removed from 15 colon cancer patients (more than 5 cm away from surgical margins) were collected as control.The content of bacterial flagellin antibodies in peripheral blood were measured with enzyme-linked immunosorbent assay (ELISA).The expression of CD98 in peripheral blood T lymphocyte was measured by flow cytometry (FACS).The expression of bacterial flagellin protein in intestinal mucosa and CD98 in intestinal epithelial basement membrane was tested by immunohistochemistry (IHC).The comparison between two groups was performed with the SNK-q method,the R×C table x2 test was used to analyze the counted data,and the Spearman correlation was used to analyze the rank materials.Results The peripheral blood concentration of bacteria flagella protein antibody of control group,mild UC group and moderate to severe group showed an upward trend,which was (7.603±2.118) pg/ml,(13.702±3.131) pg/ml and (20.813±3.004) pg/ml respectively,and the differences among groups were statistically significant (F=13.57,P＜0.01).The expression percentage of bacteria flagella protein in intestinal mucosa of the three groups also showed an upward trend,which was 3/15,56.67％ and 73.33％ respectively,and the differences among groups were statistically significant (x2 =11.553,P=0.003).The positive rate of CD98 expression in peripheral blood T lymphocytes of the three groups showed an upward trend,which was (28.42±4.31)％,(32.45±6.71)％ and (43.40±5.09) ％ respectively,and the differences among groups were statistically significant (x2 =10.110,P=0.007).The positive rate of CD98 expression in intestinal epithelial cells of the three groups also showed an upward trend,which was 1/15,36.67 ％ and 66.67％ respectively,and the differences among groups were statistically significant (x2 =5.400,P＜0.05).There was positive correlation between the peripheral blood concentration of bacteria flagella protein antibody and the expression of CD98 in peripheral blood T lymphocytes (r=0.548,P＜0.05).Conclusion Bacterial flagellin and CD98 may be important factors causing inflammatory reaction activity in UC.

OBJECTIVE: To explore whether there was tissue remodeling in the nasal mucosa of allergic rhinitis (AR) patients and detect the protein expressions of transforming growth factor beta1 (TGF-beta1), matrix metalloproteinases 9 (MMP-9) and tissue inhibitors of matrix metalloproteinases 1 (TIMP-1) in the nasal mucosa of these patients. METHOD: Pathologic staining was used to explore the mucosa of the middle turbinate tissues from 16 patients with mild AR, from 12 patients with severe AR, and from 15 non-AR, respect. The infiltrating of eosinophils and damage of epithelium were examined by the hematoxylin-eosin staining; goblet cells were counted by the alcian blue-periodic acid-schiff staining; the percentage area of extracellular matrix was determined by the MT; the protein expressions were measured by ELISA of TGF-beta1, MMP-9 and TIMP-1 in the middle turbinate tissues. RESULT: Compared with the control group, significant eosinophil infiltration and goblet cells were observed in both AR groups (P < 0.05). Evident epithelial damage and extracellular matrix deposition were observed in severe-AR group (P < 0.05). The expressions of TGF-beta1, MMP-9 and TIMP-1 in AR tissues were significant increased (P < 0.05). CONCLUSION The nasal mucosa remodeling was observed in AR groups. The characteristics were as follows: eosinophils infiltration, epithelial damage, goblet cells hyperplasia and extracellular matrix deposition. TGF-beta1, MMP-9, TIMP-1 may play a role in the tissue remodeling processes.

Objective:To explore the change in the cerebral natriuretic peptide (BNP) levels in the premature infants with hemodynamically significant patent dectus arteriosus (hsPDA) and its relationship with hemodynamics, and to further clarify the clinical significance of BNP in the judgement of illness condition and treatment in the premature infants with hsPDA.Methods:A total of 106cases of premature infants within 6hof birth whose gestational age was no more than 32weeks were selected and divided into hsPDA group (43cases) and PDA with no hemodynamic significance group (nhsPDA group, 27cases) and no PDA group (nPDA group, 36cases) .The patients in HsPDA group were divided into hsPDA treatment group (33cases) and hsPDA non-treatment group (10cases) according to whether ibuprofen was administrated or not.Echocardiography was performed in the patients in hsPDA treatment group, 7dafter oral ibuprofen administration, and the patients in hsPDA treatment group were divided into hsPDA close group (15cases) and hsPDA non-close group (18cases) .The left atrium (LA) /aortic root diameter (VO) value, diameter of patent arterial duct, left ventricular ejection fraction (LVEF) , shortening fraction, left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD) were recorded at 1, 3, 7dafter birth of the premature infants in various groups with echocardiography.The level of BNP in plasma was determined by electrochemiluminescence.The correlation analysis was performed between the hemodynamic indexes of echocardiography and the level of BNP in plasma.Results:Compared with nhsPDA group, the LA/VO value, arterial catheter diameter and LVEDD were significantly increased (P＜0.05) .The plasma BNP levels of premature infants in hsPDA close and non-close groups at 1and 3dafter birth were significantly higher than those in nPDA group (P＜0.05) ;the plasma BNP level of the premature infants in hsPDA close group at 7dafter birth was significantly lower than that at 3dafter birth (P＜0.05) .Compared with hsPDA non-treatment group, the LA/VO value, arterial catheter diameter, LEVDD and the plasma BNP level of the premature infants in hsPDA treatment group at 7dafter birth were significantly decreased (P＜0.05) .The plasma BNP level was positively correlated with the LA/VO value and arterial catheter diameter (r=0.727, P＜0.05;r=0.780, P＜0.05) of the premature infants in hsPDA group at 3dafter birth.Conclusion:The level of plasma BNP of premature infants 3 dafter birth is positively correlated with the hemodynamic indexes, and the detection of the changes of the plasma BNP levels is helpful to judge the condition of preterm infants with hsPDA and to provide basis for its diagnosis.

Objective To investigate the effect ofatorvastatin on angiogenesis of brain tissues in focal cerebral ischemia rats,and explore the corresponding mechanism.Methods Ninety male SD rats were randomly divided into sham-operated group,model group and treatment group (n=30);and then,each group was divided into three subgroups:1 d group,3 d group and 7 d group (n=10).The focal cerebral ischemia models were induced by middle cerebral artery occlusion (MCAO);3 h after MCAO,rats in the treatment group received a gavage of atorvastatin 4 mg/(kg.d),and others were given the same amount of normal saline at corresponding time.The nerve function defects were estimated at 3 h after MCAO and before being killed;the protein expressions of vascular endothelial cell markers CD105 and glucose-regulated protein 78 (GRP78) were analyzed by immunohistochemistry;the vascular endothelial growth factor (VEGF) mRNA expression was analyzed by real time-PCR;the caspase-12 protein expression was analyzed by Western blotting.Results (1) Nerve function defects scores:there was no significantly statistical difference between model group and treatment group at 3 h after MCAO (P＞0.05),but statistical differences at different time points before being killed were noted (P＜0.05).(2) Microvessel density (MVD):at all time points,that of model group was increased as compared with that of sham-operated group,that of treatment group was increased as compared with that of model group,and the differences were all statistically significant (P＜0.05).(3)The VEGF rmRNA expression gradually increased over time;at all time points,the VEGF mRNA expression of model group was significantly higher than that in the sham-operated group,and that of treatment group was significantly higher than that in the model group (P＜0.05).(4)The GRP78 and caspase-12 expressions were gradually decreased over time;at all time points,the GRP78/BiP and caspase-12 expressions in the model group were significantly higher than those in the sham-operated group;those in the treatment group were statistically lower than those in the model group,but obviously higher than those in the sham-operated group (P＜0.05).Conclusion The angiogenesis of brain tissues in MCAO rats is obvious,and atorvastatin can enhance this effect;the mechanism may be that atorvastatin can weaken the endoplasmic reticulum stress,and then,reduce the apoptosis of endothelial cells.

Objective: To explore the epidemiological characteristics of mortality of accidental injury children aged 5-19 years in Yunnan Province during 2015-2019, to provide further evidence for reducing accidental mortality in children. Methods: The mortality cases of accidental injury by gender, age groups, and causes among children and adolescents in Yunnan Province during 2015 to 2019 were analyzed retrospectively. Poisson regression model was used to estimate the trend of mortality. Chi square test was used to compare the differences of mortality by gender and age groups. Results: During 2015 to 2019, the mortality rate of accidental injury in children and adolescents aged 5-19 years in Yunnan Province decreased from 19.15/10 5 in 2015 to 18.35/10 5 in 2019 (Z=-3.36, P <0.01). The mortality rate of all types of accidental injuries in male was higher than that in female ( χ 2=867.01, 11.69 , 147.60, 190.34, 7.23, 702.97, P <0.05). The top three causes of fatal accidental injuries included road traffic accidents, drowning and falls. Except for accidental falls, the mortality rate of other causes in the 15-19 age group was significantly higher than that in the age of 5-9 years and 10-14 years groups ( χ 2=764.47, 75.91, 31.75, 9.24, 114.96, 327.64, P <0.05). The top three traffic accidents were happened among motorcyclists, light trucks or caravans and cars, accounting for 27.83%, 10.57% and 7.90% respectively. Conclusion Targeted measures should be taken continuously according to the characteristics of children and adolescents in different regions, age groups and gender to reduce the incidence and mortality of accidental injuries among children.

Objective: To understand the public health emergency response capacity in primary and secondary schools, and to explore the problems and challenges in the prevention and control of public health emergency in primary and secondary schools for specific strategies. Methods: By using the stratified group sampling method, a questionnaire survey on general situation, knowledge, attitude and training, as well as public health emergencies response capacity among 2 988 teachers or leaders responsible for school emergency response in primary and secondary schools from Beijing, Chongqing and Yunnan. Results: Participants varied on their positions, titles, educational background and knowledge accuracy. Higher knowledge accuracy was associated with higher educational background ( χ 2=50.73-203.36, P < 0.05 ). The implementation of regular public health emergency related programs was poorly conducted in high schools (50.0%). Urban schools (42.0%) had higher proportion of qualified health care professionals than rural schools (18.2%), and private schools (48.5%) was higher than public schools (24.7%). The primary challenges included the shortage of guidance from professionals and the lack of related testing equipment (84.91%, 74.03%). Conclusion Although the ability of emergency handling of public health emergencies in schools in the three regions is advancing with the times, there are still many deficiencies, some omissions in the mastery of knowledge. It is suggested to inerease pre service and special training of school health work CDC should strengthen technical guidance and work supervision of infectious disease management in schools.
