Objective To study the changes of transforming growth factor-β1(TGF-β1) in pulmonary fibrosis induced by paraquat (PQ) with immunohistochemistry method. MethodsA total of 58 C57BL/6J male mice were randomly (random number) divided into the experimental group and control group. Pulmonary fibrosis was induced by intra-peritoneal injection of PQ in dose of 10 mg/kg into the mice of experimental group (n = 48), while physiological saline was used instead in mice of control group (n = 10). The mice of experimental group were sacrificed 2, 5, 7 and 14 days after PQ poisoning and the mice of control group were sacrificed on the 7th day after saline administration. Lungs of mice were taken and histological changes in lungs were evaluated by haematoxylin-eosin stain, and TGF-β1 was determined with immunohistochemistry method. The integrated optical density (iOD) value of TGF-β1 was measured and analyzed. ResultsThe TGF-β1 was markedly increased in macrophages during the genesis of pulmonary fibrosis induced by PQ. As the course of fibrosis progressed, the positive staining of TGF-B1 was mainly seen in macrophages and neutrophil's cytoplasm. On the 14th day after PQ poisoning, TGF-β1-positive cells were also detected in the fibroblast and myo-fibroblast inside the fibroblastic foci. Compared with the control group, the iOD value of TGF-β1 increased in experimental group (P ＜ 0. 01 ) and it gradually upgraded during the course of fibrosis. Conclusions The TGF-β1 significantly increased during the course of pulmonary fibrosis induced by PQ and played an important role in the pathogenesis of the disease.

Fifty-six hypertensive diabetic patients (glyeosylated hemoglobin A1c<7%)with albuminuria were randomly assigned to benazepril (10 mg/d,n=28) or amlodipine (5 mg/d,n=28) group.Blood pressure was measured at the end of 4-week treatment.Benazepril and amlodipine were increased to 20 mg/d and 10 mg/d respectively when blood pressure>130/80 mm Hg.All the patients were treated for 12 weeks.In both groups,plasma yon Willebrand factor and urine albumin decreased significantly from baseline.Except for urine albumin,no significant inter-group difference in plasma van Willebrand factor and target blood pressure was observed.Benazepril and amledipine seem to show similar efficacy in lowering blood pressure and improving endothelial function,but benazepril may be more effective in kidney protection.

Objective To observe the adjuvant therapy efficacy of Saccharomyces boulardii sachets in liver cirrhosis patients with spontaneous bacterial peritonitis(SBP).Methods 72 liver cirrhosis patients with SBP were randomly divided into the observation group and control group.The patients in the control group (30 cases) were giv-en routine medical treatment such as anti-infection,correction of hypoproteinemia,liver protection,and diuresis,etc. At the base of the control group,the patients in the observation group (32 cases) were orally given Saccharomyces boulardii ( Baili Pharmaceutical Factory,French) 0.5g for one time,two times daily for 10 days.The changes of serum interleukin-6(IL-6),pmcalcitonin (PCT) and hypersensitive c-reactive protein (hs-CRP) levels in the two groups were observed and compared before and after treatment, and curative effect and safety were also observed. Results Before treatment,the serum IL-6,PCT and hs-CRP levels in the two groups had no obviously statistical difference(all P>0.05),but after treatment,the serum IL-6,PCT and hs-CRP levels of the observation group were much lower than those of the control group[(60.50 ±19.10) pg/mL vs (98.32 ±17.20) pg/mL,(1.80 ± 0.34)μg/L vs (6.38 ±3.56)μg/L,(6.20 ±4.15) mg/L vs (20.28 ±8.30) mg/L,t=8.147,7.246,8.529,all P<0.01].Meanwhile,the total effective rate of the observation group was significantly higher than that of the control group(93.75%vs 73.33%,χ2 =4.771,P<0.05).The incidence rate of DAR between the two groups had no obvi-ously statistical difference(9.38% vs 13.33%,χ2 =0.242,P>0.05).Conclusion Saccharomyces boulardii can significantly reduce serum IL-6,PCT and hs-CRP levels of liver cirrhosis patients with SBP,and reduce inflamma-tion reaction to control development of SBP.

Objective Boy sexual development is affected not only by age, but also by environment factors .The present study was to survey and evaluate the status of sexual development in boys from Zhengzhou area and to explore their influencing factors. Methods The height, weight, waist circumference, hip circumference, penis and testicles in 3779 boys aged from 6 to 13 years old in Zhengzhou were measured .The penis length and testicular volume of different ages and their influencing factors were compared, and the beginning age and sexual development characteristics were explored .The development of genitalia and pubes were evaluated by Tanner staging criteria and standards, which were divided into five stages. Results There were 3779 boys, including 395 overweight cases (10.45%) and 208 obesity cases (5.50%).The testicular volume and penis length increased by age, which increased slowly at the age of 6 to 11, followed by a rapid increase after the age of 11 year old.Testicular volume increased more rapidly than that of penis length. The medians quartile of testicular volume in overweight group ,obese group and normal group were 2.50 mL, 2.50 mL, 2.00 mL, 2.00 mL,2.00 mL,1.00 mL respectively .The testicular volume in overweight group and obese group were significantly greater than that in nor -mal group (P<0.01) and there were no difference between overweight group and obese group .The penis length in overweight group and obese group were significantly less than that in normal group (P<0.01), and there was no difference between overweight group and obese group.Testicular volume and penis length were positively correlated with age, height, weight, body mass index, waist circumference and hip circumference; the correlation between testicular volume and height, penis length and age were the strongest. The age of development of testicle (average 12.02 years) in urban area was later by 2.73 years than that in the rural area (average 9.9 years), the difference was statistically significant (P<0.001).The age of pubic development (P2) and maturity (P5) was (12.34 ±0.83) years and (12.39 ±1.24 ) years.The incidence of precocity in boys was 0.40%. Conclusion The sexual development of boys from Zheng-zhou area is similar to the results of large scale survey from China .Attention should be paid to the effect of obesity on sexual develop-ment, and early intervention should be given, the occurrence of adverse events of sexual development can be avoided .

A total of 100 patients with subacute thyroiditis hospitalized from January 2011 to October 2012 were recruited.Each received glucocorticoid treatment for 8 weeks and there was a 2-month follow-up period after drug withdrawal.After treatment,the short-term recurrence rate was 34％ (34/100).If thyroid ultrasound was abnormal,the recurrence rate was 52％ (30/58).And it was significantly higher than 10％ recurrence rate for those with normal thyroid ultrasound (4/42,x2 =9.67,P ＜ 0.01).The recurrence rate of different erythrocyte sedimentation rate groups of 40-100 mm/1 h and ＞ 100 mm/1 h was 37％ (22/60) and 30％ (12/40) respectively (P ＞ 0.05).

A rapid resolution liquid chromatography coupled with quadrupole-time-of-flight mass spectrometric (RRLC-Q-TOF-MS) method was established and optimized for the analysis of pharmacokinetic behavior of ginsenoside Rb2 in rats by intravenous injection administration.The metabolism of ginsenosides Rb2 in vivo rat was also explored.In the experiment,Agilent SB C18 column was selected for the sample separation with 0.1％ aqueous formic acid solution as mobile phase (A) and acetonitrile as mobile phase (B) at a flow rate of 0.2 mL/min,and the injection volume was set to 5 μL.Q-TOF-MS was carried out in electron pray ionization (ESI) negative ion mode.The limit of quantification (LOQ,S/N =10) and limit of detection (LOD,S/N=3) were 0.10 and 0.08 μg/mL,respectively,and the linear range was 0.1-1.26 μg/mL.The experiment results showed that the concentration-time profile of ginsenoside Rb2 conformed to a two-compartment pharmacokinetic model after intravenous administration for rats.The mean plasma elimination half-lives were (23.58±1.10) min (t1/2α),(1306.55±147.23) min (t1/2β) for Rb2.By analyzing the urine of rats after intravenous administration and the fecal samples after oral administration of ginsenoside Rb2,it was found that the metabolites were M6,M2 (CY),F2,and C-K.

Objective To investigate the effect of DPP-4 inhibitor sitagliptin on atherosclerosis and its mechanism.Methods Thirty male ApoE-/-mice were randomly divided into two groups:experimental group(n=15) and control group(n=15).The mice in the experimental group were fed with high-fat mixture of sitagliptin and the control group was fed with high fat.Collected blood in the eyeballs in order to analyze serum levels of blood lipids and blood glucose after 16 weeks of feeding,and detected serum nitric oxide synthase(eNOS),vascular adhesion molecule-1(VCAM-1) with ELISA method.Collected aortic tissue in order to analyze atherosclerotic plaque.Results There was no significant difference in blood glucose,triglyceride and total cholesterol level between the two groups(P>0.05).The serum high density lipoprotein in the experimental group was significantly higher than that in the control group(P<0.05).The atherosclerotic plaque in the experimental group(7.55±1.87)%, which was significantly smaller than that in the control group(11.67±1.32)%.The serum VCAM-1 in the experimental group was lower and the eNOS was higher than that in the control group(P<0.05).Conclusion DPP-4 sitagliptin can increase the expression of HDL and eNOS and inhibit the expression of VCAM-1,thereby inhibiting the progression of atherosclerosis in ApoE-/-mice.
