Objective To analyze the characteristics of pulmonary function and the clinical significance of non‐specific pattern (NSP) ,and provide basis for the clinical research .Methods A total of 120 pulmonary function tests of adult patients from January 2013 to June 2014 were selected and divided into NSP group(n=20) and normal lung function group(n=100) according to their lung function behavior .The pulmonary function test results ,clinical diagnosis and radiological manifestations were analyzed .The relevant factors affecting NSP occurred were selected and logistic regression analysis was used to analyze multiple factors .Results The FEVl ,VC ,TLC ,FVC ,MVV and FEVl/FVC in normal group were significantly higher than that of NSP group and the RV/TCL was lower than NSP group ,the difference was statistically significant (P<0 .05) .Patients in NSP group were with obstructive and (or) restrictive clinical manifestations .There were 9 patients were without lung disease .Univariate analysis showed that age , BMI ,smoking history ,smoking ,obstructive diseases ,and restrictive disease in NSP group were significantly higher than that in nor‐mal group ,the difference were statistically significant (P<0 .05) .Multivariate analysis showed that age ,BMI ,history of smoking , obstructive diseases and restrictive disease were independent risk factors for NSP (P<0 .05) .Conclusion Old age ,smoking and o‐besity could increase the incidence rate of NSP .The clinical characteristics include obstructive and restrictive ventilation defects ,and need to be identified positively .

In order to study the relationship between sex hormone and gynecomastia, the levels of plasma sex hormone in the male patients with gynecomastic were determined by using radioactive immune assay. Seventy-eight gynecomastic patients were regarded as the experimental group which was divided into 3 subgroups: the youth group with the age ≤30 years old, the middle-aged group with the age ranging from 30 to 60 years old and the old-aged group with the age ≥60 years old in the light of age and 24 normal men served as control group. The results showed that the levels of E2 and E2/T in the gynecomastia patients were much higher than in the control group (P<0.05, 0.01)；In the experimental group, the ratio of T reduction in the old-aged group was much higher than in the youth group or the middle-aged group（P<0.05). In conclusion, gynecomastia was related to the dysfunction of the level of sex hormone, to a large extent, with the increasing of estrogen. In addition, senile gynecomasti was closely related with the decreasing of male hormone.

More in the treatment group released from pain, local heat, etc. than in the control (P<0.05). Conclusion The Phlebitis Mixture is helpful for the recovery from endovenous laser treatment for varicose veins.

Two famous historical events which lead to the establishment of the medical ethics committee are presented in this article. We discuss the significance of the medical ethics committee and put forward 5 propositions to enhance the developing of the committee. Firstly, overcome the scruple and accelerate the construction of the medical ethics committee. Secondly, seek for the ethics spirit from the traditional culture, and establish the principles and the conception correspondingly. Thirdly, be creative and try to adapt to the promotion of medicine and society. Fourthly, strengthen the training of bioethics. Finally, promote the communication between ethics review committees.

Objective: T o further investigate pathogenesis about vulvovaginal candi diasis (VVC). Methods: Human normal vaginal epithelial cells in vitro were cultured by tissue cultur e and keratinocyto serum-free medium. Passaging epithelial cells were coculture d with candida albicans medium in separate wells for 0, 3, 6, 12, 24, and 48 h. C ontr ol epithelial cells were cultured alone in separate wells. For examination o f cytokines and chemokines, at each time point, the coculture supernatant and th e control culture were collected. ELISA was applied to detect the levels of HBD -1, HBD-2 and SP-A protein expression in the vaginal epithelial cells (HBD-1 :F= 62.784,P=0.001; HBD-2: F=5127.984, P=0.000; F=542.210, P=0 .000). Also, we colle cted the vaginal doughing water of VVC patients and healthy women, and detected the levels of SP-A, then analysed the data. Results: In the tra il of human vagin al epithelial cells, in contrast to the control group, the medium group induced the epithelial cells to secrete more HBD-1, HBD-2 and SP-A at h48, which was co nsidered to be significant (P

Objective To study the characteristics of peripheral nerve conduction (PNC) in advanced-stage amyotrophic lateral sclerosis (ALS) patients undergoing mechanical ventilation.Methods The sensory conduction velocity (SCV),motor conduction velocity(MCV),distal motor latency(DML) and amplitude of compound muscle action potential(CMAP) were determined in three ALS patients undergoing mechanical ventilation.The clinical data and PNC characteristics of the patients were analyzed.Results The 12 motor nerves were abnormal in all the three patients,including absence of responsive wave (66.7%,8/12),decreased amplitude of CMAP(33.3%,4 /12),prolongation of DML(16.7%,2 /12) and reduction of MCV(16.7%,2 /12).The CMAP amplitude of patients gradually decreased with the progression of disease,and finally led to adverse reactions.The SCV and amplitude of sensory nerve action potential were normal in all the three patients.Conclusion ALS patients undergoing mechanical ventilation may have severely damaged motor nerve conduction,and their sensory nerve is generally not affected,with the specific reason remains to be further studied.

Objective To observe the efficacy of folic acid combined with mecobalamine for the treatment of vascular mild cogni-tive impairment (VMCI) in patients with cerebral small vessel disease (SVD) and hyperhomocysteinemia(Hcy) .Methods A total of 84 VMCI patients with cerebral small vessel disease and Hcy were randomly divided into combination group and control group . Two groups received conventional therapy for 6 months .Besides ,the combination group received folic acid combined with mecobal-amin .The level of plasma Hcy and ADAS-cog score were observed before and after 3 months and 6 months treatment .Results Af-ter treatment ,plasma Hcy significantly lower in the combination group (P<0 .01) ,whereas it did not show any improvement in the control group .ADAS-cog scores in combination group decreased compared with that of before treatment ,but there was no statisti-cally significant difference after 3 months treatment(P>0 .05) .However ,after 6 months treatment ,the ADAS-cog scores decreased obviously than that in the before treatment group (P<0 .05) .ADAS-cog scores in control group increased compared with before treatment ,but there was no statistically significant difference in after treatment (P>0 .05) .After 3 months treatment ,there was no significant difference on ADAS-cog score between combination group and control group (P>0 .05) ,however ,there had significant difference between the two groups after 6 months treatment(P<0 .05) .Conclusion The level of plasma Hcy could be reduced by adding folic acid and mecobalamin .Treatment of hyperhomocysteinemia may delay the progression of vascular cognitive impairment w hich caused by cerebral small vessel disease .

Objective To study the influence of finasteride on the expression of hypoxia-inducible factor 1 α(HIF-1 α) and vascular endothelial growth factor (VEGF) with prostate cancer (Pca).Methods The patients diagnosed of Pca were selected,and which treated with finasteride for up to six months were finasteride group and untreated with finasteride were control group.The expression of HIF-1 α,VEGF and microvessel density(MVD) was examined.Results The positive expression of HIF-1α,VEGF and MVD in the finasteride group were 55.0％,57.5％,(56.9 ± 13.8),respectively,and were lower than those of the control group [87.5 ％,97.5 ％,(64.2 ± 13.3)] (x2 =10.313,18.122,all P ＜ 0.01 ; t =2.391,P ＜ 0.05).In the pathological grade,advanced grade of the finasteride group was in 15 cases(37.5％),and 10 cases(25.0％) was in the control group,and the difference was statistically significant between the two groups(x2 =1.455,P ＞ 0.05).Conclusion Long-term treatment with finasteride can reduce expression of HIF-1α and VEGF with Pca,thus inhibit angiogenesis and tumor growth and metastasis.
