Objective：To confirm the effects of the macrophages and NO in the fibrosis formation of transplanted kidneys with chronic rejection. Methods：The quantitive immunohistochemistry was employed to observe the changes of relative quantitiy of macrophages, NO, collagen Ⅲ andⅣ， and to reveal the association between the increases of macrophages， NO， histopathologic damages, deposition of collagen Ⅲ and Ⅳ, finally, to infer the roles of the macrophages and NO in the fibrosis formation of transplanted kidneys with chronic rejection. Results: The macrophages accumulated and increased in the glomeruli, the tubules and the intersiticia tissue of kidneys, which was companied by the increased expression of collagen Ⅲ and Ⅳ during the early and middle stages. However, the macrophages and NO could not be detected, which was companied by the decreased deposition of collagen Ⅲ and Ⅳduring the advanced stage. There were significant differences between the 3 types(glomerulus disease type,blocking vessel type and intersticial sclerostic type) (P<0.05 or P<0.01). Conclusion：The increase of macrophages and the NO may closely interrelated with the fibrosis formation in transplanted kidneys with chronic rejection.

Objective To evaluate the diagnostic and therapeutic status of elderly benign prostatic hyperplasia (BPH).Methods Totally 188 male elderly in outpatient department from January 2010 to March 2012 were enrolled in this study.Medical history was inquired in detail,and prostatic volumes (PV)were measured by abdominal ultrasound,PV≥ 20ml was diagnosed as BPH.Lower urinary tract symptoms (LUTS) was evaluated by international prostate symptom score (IPSS),prostate specific antigen (PSA) was measured.Age≥62 years,PSA≥1.6 μg/L and PV≥31 ml were considered as higher risk of clinical progression of BPH.We investigated the rate of prevalence,awareness and treatment of BPH.PV,IPSS and PSA were compared among different age groups by ANOVA.Logistic regression analysis was made to show the risk factors of BPH.Results Among 188 male elderly,the prevalence rate of BPH was 48.4％,and the total rate of awareness was 41.5％.The rate of awareness resulting from seeing doctor due to LUTS was 10.6％.PV,IPSS and PSA were increased with ageing.Risk factors contributing to BPH were age,hypertension and diabetes.The treatment rate with drugs of 5a-reductase inhibitor was 47.3 ％,however 10 subjects had not been given drugs treatment among 46 patients with higher risk of clinical progression of BPH.Conclusions The prevalence rate of BPH is increased with ageing,the proportion of seeing a doctor with passion is lower because the male elderly have not paid enough attention to LUTS.And doctors have not given drugs intervention to patients with clinical progression BPH in time.We should launch propaganda and education among the elderly patients with hypertension and diabetes and take comprehensive treatment.

Objective To investigate the relationship between benign prostatic hyperplasia (BPH) and urine albumin excretion.Methods A total of 258 male inpatients aged 60 to 70 years were enrolled in this study.According to prostate volume (PV) measured by transrectal ultrasonography,patients were divided into BPH group(PV≥20 ml) and NBPH(non benign prostatic hyperplasia) group(PV＜20 ml).Urine albumin and urine creatinine concentrations were measured and urine albumin/creatinine ratio(UACR) was calculated.Fasting blood glucose(FBG) and fasting insulin(FINS) also were measured,insulin resistance index(HOMA-IR) was calculated based on the formula HOMA-IR=ln(FBG × FINS/22.5).The correlation between PV and other indicators were analyzed by Pearson correlation analysis.The risk factors for BPH were analyzed by logistic regression analysis.Results UACR was significantly higher in BPH group than in NBPH group[(163.6± 69.8) mg/g vs.(73.3 ± 55.6) mg/g,t =4.81,P＜ 0.01],and hypertension duration was longer in BPH group than in NBPH group [(9.2±6.6)years vs.(6.0±3.6)years,t=2.27,P＜0.05].The prevalence rate of BPH and PV were increased along with increasing of urine albumin excretion(x2=4.58,F=4.85,respectively,P＜0.05 or 0.01).Prostate volume was positively correlated with UACR,HOMA-IR,hypertension duration,body mass index(r=0.248,0.229,0.183,0.157,respectively,all P ＜ 0.05).Logistic regression analysis indicated that UACR,HOMA-IR and hypertension duration were the risk factors for BPH(OR=16.348,1.040,0.166,respectively,all P ＜0.05).Conclusions BPH is correlated with UACR,which indicates that there is a close relationship between atherosclerosis and BPH.Insulin resistance probably plays an important role in the progression of arteriosclerosis and BPH.

PURPOSE To investigate the relationship between the changes of extracellular matrix invaded by colorectal carcinoma and vascular endothelial cells,which will be useful to understand colorectal carcinoma biological behavior and may have clinical significance in the treatment of colorectal carcinoma.METHODS Immunohistochemistry technique and semi quantitative analysis were used.RESULTS As to the changes of ECM and endothelial cells,there were significant differences among the paracarcinoma groups,different invasive groups and normal group.THe increase of LN,CD34,F8 and actin were correlated with colorectal carcinoma invasion( P

In this study, two experimental patterns of autogenous nerve replantation in situ and centrocentral nerve simple suture were performed on the rabbit median and ulnar nerves. By light and transmission electron microscopy and immunohistochemistry, the results showed that autogenous nerve replantation in situ could inhibit neuroma formation, and its mechanism might that two proximal stump axons could conjunct within interpolated graft segment, and the nerve simple suture could not inhibit neuroma development for lack of proper environment for conjunction of two proximal stump axons.

Mimecan belongs to a family of leucine-rich proteoglycans that are secreted into the extracellular matrix. In order to investigate the function of mimecan, the coding region of mimecan was amplifed from a human pituitary cDNA by PCR and the recombinant prokaryotic expression vector pGEX-M was constructed. The vactor was transformed into E.coli BL21(DE3)and the GST-M fusion protein of 38 Kd was ecpressed in the bacteria under induction of IPTG. After purification, the fusion protein was infucted into New Zealand rabbits to prepare polyclonal antibody. The antibody was tested by Western blotting for their specificity and sensitivity. Using the antibody it was found the mimecan was expressed highly in certain types of human pituitary tumor tissues. These results make it possible for studying the biological function of mimecan.

Objective To evaluate the outcomes of the payment reform at public hospitals in Sanming city.Methods Interrupted time series analysis was used to compare changes of the average days of stay,per capita hospitalization expense,outpatient expense per visit,proportion of medical expense and that of drugs during hospitalization at 21 public hospitals at or above county level before and after the DRGs reform.Results Comparisons before and after the reform found the average days of stay at the original momentum,poor control in curbing the proportion of medical expense and that of drugs during hospitalization,adropping followed by rising trend in the outpatient expense per visit,and minimal drop of the abovementioned proportions.Conclusions The rapid growth of outpatient and hospitalization costs at tertiary hospitals may be incurred by unreasonable cost transfer,structural trend of hospitalization expense makeup,and rationality pending scrutiny.

Tripartite-sector reform (a synergistic reform in public health services,medical insurance and medicine production-circulation) in Sanming city was described in the paper which centers on medical insurance.Tapping full potentials of the medical insurance,the city achieved efficient synergy among healthcare,medical insurance and medication systems.This reform has trimmed out inflated drug pricing to some extent for rooms of maneuver of medical service pricing changes,thus curbing excessive growth of medical costs successfully.The authors proposed areas of further improvements including the relationship between achieving such objective as curbing medical expenditure,and advancement of technical/medical service capacity;that between integrative control of medical insurance expenditure and protection of people's health;the equilibrium of interests between medical insurance,healthcare and medication.All these will contribute to the goal of healthy patients flow and a hierarchical medical system.

Covered in the paper are the significance of rural doctors′professional development and their professional characteristics,as well as systematic insights on such key factors of professionalism of these doctors,as their professional qualifications,functional positioning,practicing approach,professional guarantee,professional development,social identity,professional stability,and professionalism.Based on such thoughts,the authors recommend on reforms of professional development for rural doctors by stages and levels.

Background The diseases of neuro-ophthalmology are common,which can influence the quality of patients' life seriously.The 39-item National Eye Institute Visual Function Questionnaire (NEI VFQ-39) is an instrument to assess self-reported visual impairment in studies of vision.However,until now,no studies have been performed to specifically assess the vision-related quality of life in persons with diseases of neuro-ophthalmology.Objective To evaluate vision-related quality of life for neuro-ophthalmology inpatients through the NEI VFQ-39,for the better treatment and nursing for them.Methods Ninety-seven neuro-ophthalmology inpatients were scheduled in research from June 1 to September 30,2012,and we collected all the clinical datas and the Chinese version NEI VFQ-39.The NEI VFQ-39 subscale item scores were compared among subgroups divided by monocular or binocular incidence,diseases and best corrected visual acuity(BCVA),and correlation analysis of the NEI VFQ-39 scores and BCVA for better-seeing and worse-seeing eyes was performed.Results The mean age of scheduled patients was (36.6±14.4)years,with no difference in gender.The mean composite score of VFQ-39 was 57.36(46.50,73.38),mental health subscale score was lowest [45.00 (35.00,60.00)].In the four eye diseases groups,except for eye pains,degree of dependence,periphery vision,anterior ischemic optic neuropathy (AION) group had lower scores compared with the other three groups,but there were no statistical significances among the four groups (all at P＞0.05).Except for eye pains,patients with monocular incidence had better scores than those with binocular incidence,with statistical significant significances between them(all at P＜0.05).Patients with BCVA in the better-seeing eye ＞ 20/32 had better scores than the other two groups,compared with the BCVA in the better-seeing eye ＜20/200 group,except for overall health and eye pains,cornpared with the 20/200 ≤ BCVA in the better-seeing eye ＜20/23 group,except for eye pains,social activity and color vision,and the rest subscale scores had significant differences among the three groups(all at P＜0.05).NEI VFQ-39 scores had positive correlations with the BCVA for better-seeing and worse-seeing eyes,and had strong correlations with the BCVA for better-seeing.Conclusions Neuro-ophthalmology diseases have serious influences on patients' visual function and quality of life.The quality of life has direct correlation with BCVA,so improving their visual function is helpful to their quality of life.
