Objective To discover the effective component of Rhizoma Tupistrae chinensis with inhibiting angiogenesis. Methods Several parts of Rhizoma Tupistrae chinensis were obtained by using different extraction solvents. They were screened by the model of ECV304 cell membrane chromatography with anti-VEGF antibody as a control drug. The inhibition of effective component (ZGQ-C) on ECV304 proliferation in vitro was examined by MTT assay. Results The inhibition rate (40.51%,51.11%,63.54%,74.32%,81.26%) was correlated with the ZGQ-C concentration. The ECV304 cell had significantly changed in morphology. Conclusion The ZGQ-C is an effective component for inhibiting angiogenesis. The screening results on the model have a good correlation with that of MTT assay.

Calcineurin inhibitors,such as cyclosporin A and tacroli mus,are widely-used i mmuno-suppressive drugs clinically.However,renal toxicity,hyperglycae mia and other side-effects can occur over long-term use.Isolation of novel calcineurin inhibitors fro m medicinal plants in recent years has pro-vided a new approach to the development of new immunosuppressive drugs with high efficiency and low toxicity.Recnt studies have shown that medicinal plant extracts, such as isogarcinol, quercetin, kae mpferol,phenylethanoid glycosides,ere mophilane sesquiterpenes A and B,pisiferdiol,as well as extracts fro m Smilax china L and Jasminum humile L,have obvious inhibitory effect on calcineurin.

Objective To explore the expression of circadian clock gene Per2 in the tissue of esophageal cancer and the relevance between VEGF,cyclin D1.Methods 80 cases with esophageal cancer who received surgical treatment and pathological specimens preserved were selected,and the normal tissues adjacent to carcinoma were used as control.The expression of Per2,VEGF and cyclin D1 were detected by immunohistochemistry,and the data were analyzed.Results Compared the tissue adjacent to carcinoma with carcinoma tissue,Per2,VEGF and cyclin D1 expression had statistically significant differences(x2 =26.86,24.34,23.72,all P ＜0.01).Per2 expression in different differentiation degree and the TMN stages had statistically significant differences (x2 =6.45,7.77,all P ＜ 0.05) ;cyclin D1 expression in lymph node metastasis and TMN stages had statistically significant differences(x2 =12.99,8.99,all P ＜ 0.01) ;VEGF expression in lymph node metastasis and TMN stages had statistically significant differences(x2 =6.68,6.14,all P ＜ 0.01).Per2 expression was negatively correlated with VEGF,cyclin D1 expression (r =-0.644,-0.523,all P ＜ 0.01).Conclusion Clock gene Per2 and VEGF,cyclin D1 expression in esophageal cancer has certain correlation,it can be a prognostic indicator of esophageal cancer.

The efficacy and safety of Saccharomyces boulardii in treatment of candida esophagitis was investigated by a single center, prospective, open label and non-inferiority trial.Eighty nine patients with candida esophagitis attending in Shanxi Provincial People′s Hospital during April 2015 to March 2016 were randomly divided into Saccharomyces boulardii group (45 cases) and nystatin group (44 cases), and oral Saccharomyces boulardii powder and Nystatin tablets were given to two groups respectively.The curative effect was evaluated by gastroscopy after the treatment.The results showed that the cure rate of Saccharomyces boulardii group and nystatin group was 68.9%(31/45)and 63.6%(28/44), and the Saccharomyces boulardii was noi inferior to nystatin (x2=3.027, P<0.05).Chi-square test showed that there was no significant difference in effective rate between two groups [91.1%(41/45)vs.93.2%(41/44), x2<0.001, P>0.05].The incidence of adverse reactions in boulardii group was significantly lower than that in nystatin group [2.2%(1/45) vs.22.7%(10/44), x2=8.636, P<0.05].The study suggests that the cure rate of Saccharomyces boulardii is not inferior to nystatin in treatment of candida esophagitis, while the incidence of adverse reactions of Saccharomyces boulardii is lower.

OBJECTIVE To get the message of drug sensitivity and characteristic of Candida infecting patients in our hospital. METHODS The CHROMagar candida color medium was applied to isolate and identify Candida strains.Drug sensitivity was analyzed by the K-B slip diffusion method. RESULTS Totally 393 strains of Candida in our hospital were isolated in the three years,including Candida albicans;C.tropicalis;C.glabrata;(C.krusei);Cryptococcus neoformans and the others;and their infection rate was 63.10%,12.47%,9.41%,8.40%,1.53%,and 5.09%,respectively.Among all strains,156(39.69%) strains were isolated from sputum,(66(16.79%))from stool,45(11.45%) from urine,38(9.67%)from leucorrhea,and 34(8.65%)from throat swabs.Sensitivity results to nine antifungals showed that 5-flucytosine,fluconazole,clotrimazole,amphotericin B,and nystatin had higher drug sensitivity to these fungi. CONCLUSIONS Isolated rate of Candida is higher from clinical samples.Drug sensitivity of different Candida to various antibiotics is different.Culturing and drug sensitivity of Candida should be put on important place and antibiotics should be used reasonably based on drug sensitive test to reduce drug resistance.

Objective To investigate the differences in sex hormone levels between hypospadias and circumcision groups.Methods Fifty cases of circumcision and 137 cases of hypospadias the dihydmtestosterone (DHT) value was tested with radioimmunoassay,and testosterone was tested with lightimmunoassay.Results DHT value was (64.51 ±32.10)pg/ml in circumcision group,and (46.72 ±28.94)pg/ml in hypospadias group (P ＜0.05).DHT value in hypospadias type Ⅰ,Ⅱ,Ⅲ,and Ⅳ were (50.20 ±32.90)pg/ml,(46.63 ±25.67)pg/rnl,(51.60 ±32.16)pg/ral,and (39.02 ±26.32)pg/ml,respectively (P =0.29).The differences between circumcision and hypospadias groups were statistically significant (P =0.00).Luteinizing hormone (LH) and testosterone (T) in children with hypospadias were significantly lower than those in children in the circumcision group (P ＜ 0.05).No statistically significant difference was found between two groups in follicle-stimulating hormone (FSH),estradiol (F2),and prolactin (PRL) (P ＞ 0.05).No statistically significant differences were found in FSH among all types of hypospadias (P ＞ 0.05).Conclusions Inadequate secretion of T or activity insufficiency and functional deficiency of 5 alpha reductase (SRD5A) are likely found in children with hypospadia.Inadequate secretion and low T value might be found in LH-T shaft in children with hypospadia.The normal T value in some children with hypospadia does not show that androgens produced during pregnancy are normal.

Objective To observe the influence of smoking on lower airway bacterial colonization(LABC)in stable phase of chronic obstructive pulmonary disease(COPD).Methods 104 patients with moderate or severe COPD were divided into three groups:42 cases smoking continuously were divided into A group,36 cases quit smoking were B group,34 non-smoker were C group.Induced sputum were analyzed for quantitiative bacteriology and bacterial culture,pulmonary function was evaluated at begining and in two years later.Results Smokers has higher positive rate of LABC than non-smokers;patients in B group has significantly lower positive rate of bacterialculture in quit smoking 2 years late than before,and significantly lower than that in A group;bacterial colonization in A group and B group include Streptococcus pneumoniae,Haemophilus influenzae,Moraxella catarrhalis; patients in B group quit smoking 2 years late and patients in C group has significantly lower positive rate of Pseudomonas aeruginosa,significantly decreased exacerbation frequency and decline of FEV1 than patients in A group.Conclusion Smoking increase positive rate of LABC in patients with moderate or severe COPD.Smoking is an important factor in deterioration of lung function in COPD.there is positive significance to quit smoking in patients with COPD.

Objective To detect the expression of Per2 and VEGF in NSCLC tissue,and analyze its clinical significance.Methods The expression of Per2 and VEGF was measured in 60 NSCLC and 20 normal lung tissue by immunohistochemistry assay,then the relation with clinicopathological parameters was analyzed.Results The positive expression rate of Per2 in NSCLC and in normal lung tissue were 71.7％ and 95.0％ ( x2 =4.683,P ＜0.05 ),while the positive expression rate of VEGF were 58.3％ and 15％ (x2 =11.295,P ＜ 0.01 ).The negative expression of Per2 in NSCLC was correlated with pathological differentiation or TNM stage( x2 =4.413,6.179,all P ＜0.05),while the positive expression of VEGF in NSCLC was correlated with pathological differentiation or lymphatic metastasis (x2 =6.524,P ＜ 0.05 ).The expression of Per2 was negatively correlated with the expression of VEGF in NSCLC (r =-0.381,P ＜ 0.01 ).Conclusion The overexpression of VEGF in NSCLC may contribute to invasion and metastasis,while Per2 may be a beneficial prognosis factor in patients with NSCLC.

Objective To observe the effects and feasibility of using walking and breathing exercises to help patients with chronic obstructive pulmonary disease in the community.Methods A hundred and one communitydwelling patients with moderate to severe chronic obstructive pulmonary disease were randomized into an experimental group (51 cases) and a control group (50 cases).The control group was given conventional pharmacotherapy,while the experimental group was given quantified walking (i.e.walking for a pre-set number of steps daily) and breathing exercises (15 minutes,3 sessions daily) to do at home for 48 weeks in addition to the conventional pharmacotherapy,.Both groups were evaluated before and after the 48 weeks of treatment using the 6-minute walk test (6MWT),a clinical COPD questionnaire,Medical Research Council (MRC) dyspnea scoring,a general anxiety/depression questionnaire and a pulmonary function test.In addition,days of hospitalization and incidence of acute exacerbation were also recorded and compared between the 2 groups.Results Among the 101 cases,92 (91.1％) completed the study (45 in the experimental group,47 in the control group,a difference which was not statistically significant).After treatment,the average 6MWT distance in the experimental group was significantly increased and significantly greater than that in the control group.No statistically significant intra-group or inter-group differences were observed with regard to the pulmonary function test or the MRC dyspnea scores.Intra-group comparison and inter-group comparison of the clinical COPD questionnaire scores and anxiety/depression scores did,however,reveal statistically significant differences.There was no significant difference in the average number of acute attacks or in the length of hospital stays.Conclusions Quantified walking and breathing exercises are effective and feasible therapy for patients with chronic obstructive pulmonary disease in the community.

Objective To explore the effects of seretide (salmeterol 50 μg and fluticasone propionate 500 μg) on lower airway bacterial colonization (LABC) in the patients with stable moderate-tosevere chronic obstructive pulmonary disease (COPD).Methods A total of 84 patients with moderate-tosevere COPD were divided into 2 groups,i.e.test (n =43) and control (n =41).The control group received basic treatment while the test group seretide 50/500 μg per inhalation twice daily for 2 years plus basic treatment.Induced sputum specimens were analyzed for quantitative bacteriology and bacterial culture.The pulmonary function key parameters and exacerbation frequency were compared between two groups at pre- and post-therapy.Results The test group has significantly a lower positive rate of bacterial culture in the lower respiratory tract than before(16.3％ vs.34.9％,x2 =3.9091,P =0.0480).While in the control group,the positive rate of bacterial culture stayed almost the same as compared with that at pre-therapy (x2 =0.2253,P =0.6350).The test group had significantly decreased exacerbation frequency than the control group (1.9±2.1 vs.2.9 ±2.3,t =2.0364,P =0.0449);FEV1 of the control group decreased by (0.0885 ± 0.0186)L in 2 years and decreased by (0.0807 ± 0.0165)L in the test group.Significant differences existed in two groups (t =2.0355,P =0.0450).Conclusion The treatment of seretide can decrease LABC,slow decreasing trend of lung function and improve clinical symptoms in the patients with stable moderate-to-severe COPD.
