Aim To study the effect of activating Sonic hedgehog( Shh) pathway on the function of endothelial progenitor cells ( EPCs ) in type 1 diabetic mice. Methods EPCs were isolated and cultured by density gradient method from diabetic mice. The effects of Shh N-terminal peptide and agonist SAG on EPCs prolifera-tion were evaluated by using the MTT colorimetric as-say. EPCs migration was measured by Transwell meth-od. EPCs tube formation ability was estimated by Matrigel . EPCs senescence activity was determined by β-galactosidase staining. Results Compared with control mice, the function of EPCs in type 1 diabetic mice was impaired. The proliferation, migration and tube formation of diabetic EPCs could be promoted by Shh peptide and agonist SAG. The senescence of dia-betic EPCs could be decreased by Shh peptide and ag-onist SAG. Conclusion Activating Shh signaling pathway can improve the impared function of diabetic EPCs in type 1 diabetic mice.

Influenza virus is a virus causing upper respiratory tract infection disease with high morbidity and mortality. China is considered as an area with high rate of influenza morbidity. Prevention and treatment of influenza currently rely on vaccines and antiviral agents in the world. In addition, traditional Chinese medicines also have been used in clinical for influenza therapy. In vitro anti-influenza virus activities of 10 traditional Chinese medicines were studied by cytopathic effect (CPE). Qingre Jiedu oral liquid (factory H) had strong antiviral activity against influenza virus A/Guangdong Luohu/219/2006 (H1N1); Yinhuang oral liquid had strong antiviral activity against influenza virus A/Hanfang/359/95 and A/Yuefang/243/72 (H3N2). Qingkailing oral liquid (factory G) had strong antiviral activity against influenza virus A/Jifang/15/90 (H3N2). Qingre Jiedu oral liquid (factory H) had strong antiviral activity against influenza virus A/Jifang/15/90, A/Yuefang/243/72 (H3N2) and virus B.

Ribavirin is a broad-spectrum inhibitor against several unrelated DNA or RNA viruses in vitro and in vivo. In this paper the in vitro and in vivo study of anti-influenza virus activity of ribavirin (RBV) injection had been reported. The in vitro antiviral activity of ribavirin injection against influenza virus A and B was studied by CPE. The in vivo protective action of ribavirin injection against influenza A/FM/1/47(H1N1) mouse adapted strain infected mouse was studied with mouse model. The results showed ribavirin injection has strong inhibitory activity against 7 virus strains tested in vitro. Ribavirin injection could significantly increase virus infected mouse survival rate and survival days and improve lung pathogen and lung index.

Purpose To investigate the clinicopathological and immunohistochemical features of primary small cell carcinoma of the cervix ( SCCC) and its prognosis. Methods 18 cases of primary cervical small cell carcinoma were evaluated by histopathology, in si-tu hybridization and immunohistochemistry and relevant literatures were reviewed. Results The age of the patients ranged from 30 to 69 years ( mean age, 40 years) . Major clinical manifestation was irregular colporrhagia. Colposcopy often revealed a cervical mass or cervical erosion. Microscopically, the tumor cells were small and round and arranged in a solid distribution. The cell had little cyto-plasm and increased karyoplasmic ratio with deeply stained granular chromatin and increased pathological mitosis. Immunohistochemi-cally, the tumor cells were often positive for CKpan, variable positive for Syn, NES, CgA, CD56 and p16. HPV 16/18 were positive in 4 cases. Conclusion SCCC is a neuroendocrine tumor of high malignancy and poor prognosis with a possible pathogenesis of HPV 16/18 infection. CKpan, Syn, CgA, NSE and CD56 are useful markers for the diagnosis of SCCC.

Objective To study the relationship between glycemic control and platelet parameters in newly diagnosed type 2 diabetic patients. Methods Ninety patients newly diagnosed as type 2 diabetes and 90 healthy people were enrolled into the study. Their blood pressure, platelet parameters, including blood platelets count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), fasting blood glucose (FPG),HbA1c ,triglyceride ( TG ), total cholesterol ( TC ), high density lipoprotein cholesterol (HDL-C ), low density lipoprotein cholesterol(LDL-C) were examined and the data were analyzed. Results The level of FBG, TG, TC,MPV and PDW of patients newly diagnosed as type 2 diabetic were significantly higher than those of healthy people (t =6. 405,2. 069,2. 633,2. 178,2. 103 ;P =0. 001,0. 046,0. 010,0. 031 and 0. 043 respectively); The level of FBG, HbA1c, TC, TG, MPV and PDW in the diabetic patients, with their HbA1 c ＞ 7%, were significantly higher than the patients with HbA1c ≤ 7 % ( t = 5.691,2.013,2. 345,3. 467,4. 016,2. 893, P = 0. 001, 0. 038,0. 029,0. 013, 0. 004, 0. 026 ). There were positive correlations between MPV and HbA1c ( r = 0. 389 P =0. 020), MPV and PDW ( r = 0. 324 P = 0. 01 ) in diabetic patients, but no correlation between MPV and FBG,MPV and Systolic BP or MPV and Diastolic BP (Ps ＞ 0. 05 ). The level of FBG, HbA1c, TG, MPV and PDW decreased significantly in the diabetic patients with HbA1c ＞ 7% after treatment (t = 5. 591,2. 301,2. 410,2.204,2.105; P=0.001,0.031,0.023,0.035,0.041, respectively).Conclusion The platelet activity enhanced in newly diagnosed type 2 diabetic patients, platelet activity can be recovered through glycemic control,which may prevent the role of platelet in diabetes complications in these patients.

Objective To investigate the risk factors of severe hand,foot and mouth disease (HFMD).Methods 175 severe cases of HFMD and 183 mild cases of HFMD in the same period were randomly selected.Single factor analysis was first performed between severe and mild cases on age,gender,residence,symptoms,signs and laboratory examinations,etc,to screen out the related risk factors which P value ＜ 0.05.Then,binary logistic regression analysis was carried out to determine risk factors most related to severe HFMD.Finally,receiver operating characteristic curve (ROC) analysis was performed on severe HFMD related risk factors.Results Single factor analysis showed that there were obvious differences between children with mild HFMD and those with severe HFMD in the factors like difficulty in breathing,walking instability,vomiting,limb shaking,disturbance of consciousness,convulsions,cold sweat and weakness,thermal process,the degree of fever,pulmonary rales,heart rate,serum EV71 antibody,circulatory failure,leukocyte count,platelet count,neutrophil ratio,CRP,blood glucose,etc (x2 =15.236,19.819,33.823,52.670,12.984,10.180,29.318,52.932,34.544,14.615,46.633,31.407 and 5.303,t =3.184,3.144,2.256,2.244 and 2.828,,all P ＜0.05).Binary logistic regression analysis showed that the thermal process,startle tremor or limb jitter,serum EV71 antibody,vomiting,fever,neutrophil ratio were the related risk factors of severe HFMD (B value =2.605,2.129,1.409,1.185,0.841 and 0.103,all P ＜ 0.05).ROC analysis showed that the areas under the curve of the predicted probability and thermal process were larger than any other risk factors [(95％ CI (0.888 ～ 0.961) and (0.818 ～ 0.920)],and thus had better diagnostic values.Conclusion Children under 3 years old were the high risk population of HFMD.Such clinical symptoms as persistent high fever,vomiting,startle tremor orlimb jitter,EV71 antibody in serum and increasing neutrophil ratio were risk factors for severe HFMD.The predicted probability had more diagnostic value than any other risk factors.

Cycloheximide (CHX) inhibits protein synthesis in most eukaryotic cells and it is a well-known tool commonly used in biochemical research. In this paper, the antiviral spectrum of CHX against several DNA and RNA viruses have been evaluated. CHX showed strong inhibitory activities against several RNA viruses such as HIV-1, influenza viruses, coxsackie B virus, enterovirus (EV71) and several DNA viruses such as HSV and HCMV. Especially the strong inhibitory activities of CHX against coxsackie B virus and enterovirus caught our attention, since effective drugs available in clinic are limited. The SAR of CHX derivatives also has been discussed in the paper. The hydroxyl group at C-2' and carbonyl group at C-2" of CHX are essential for its antiviral activity. And modification to these groups results its derivatives' antiviral activities reduced or lost.

Objective To study the effect of dexmetomidine on tracheal intubation under abdominal anesthesia.Methods From January 2015 to January 2018,100 patients were selected to perform tracheal intubation under abdominal anesthesia in Shanxi Provincial Hospital of Taiyuan.A total of 100 patients under abdominal surgery were randomly divided into two groups,with 50 patients in each group.The observation group was given dexmetomidine intravenous injection during the operation,while the control group was not given dexmetomidine during the operation.The blood pressure and heart rate of the two groups were compared before and after anesthesia.The recovery time of spontaneous respiration,eye opening time,extubation time,incidence of adverse events,cough score and restlessness score were compared between the two groups,and the cognitive function of the two groups was compared.Results After anesthesia,the systolic blood pressure [(103.75 ± 2.26) mmHg],diastolic blood pressure [(71.92 ± 1.95) mmHg],heart rate[(70.91 ± 1.89) rpm] in the observation group were significantly higher than those in the control group [(100.37 ±2.91)mmHg,(70.27 ± 1.84)mmHg,(69.08 ±1.63)] (t =6.487,4.532,5.185,all P ＜0.05).The recovery time of spontaneous respiration [(7.14 ± 1.37) min],eye opening time [(9.85 ± 2.31) min] and extubation time[(20.57 ±2.94)min]in the observation group were significantly shorter than those in the control group[(8.75 ± 1.89)min,(12.41 ±2.97)min,(24.06 ±3.42)min] (t =4.877,4.811,5.472,all P ＜0.05).The incidence rate of adverse events in the observation group (8％) was lower than 24％ in the control group (x2 =4.762,P ＜ 0.05).The score of cough and the score of restlessness in the observation group were (4.09 ± 1.63) and (4.27 ± 1.96),respectively,which were significantly lower than those in the control group [(6.24 ± 2.18) and (6.51 ± 2.32)] (t =5.186,5.215,all P ＜ 0.05).At 6 h after operation,the scores of MMSE,vocabulary memory,simple calculation and picture memory in the observation group were (23.95 ±2.13),(7.35 ± 1.08),(7.14 ± 1.12) and (7.26 ± 1.17),respectively,which were higher than those in the control group[(20.47 ± 1.91),(6.17 ± 0.94),(5.89 ± 1.04),(6.02 ± 0.89)] (t =8.601,5.828,5.783,5.965,all P ＜ 0.05).Conclusion The application of dexmetomidine in patients under general anesthesia under tracheal intubation can effectively reduce the fluctuation of hemodynamic indicators after anesthesia,help to maintain the hemodynamic stability of patients,and promote the recovery of consciousness after operation.It can prevent adverse events during recovery of anesthesia and reduce the effect of anesthesia on cognitive function of patients.
