Objective To investigate the short and long term therapeutic effects of prostaglandin E1 (PGEl) on diabetic nephropathy (DN). Methods Patients with DN in stage Ⅲ to Ⅴ according to Mogensen criteria were randomly assigned to four groups of PGE1, angiotensin-converting enzyme inhibitor (ACEI), PGE1 + ACEI and control drug. The levels of proteinuria and albuminuria were measured before and 15 days, 6 months and 18 months after treatment. Patients with DN in stage Ⅳ were subdivided into three groups according to proteinuria: early stage IV (protienuria was less than 1.5 g/d), middle stage Ⅳ (protienuria was between 1.5 g/d and 2.5 g/d) and late stage Ⅳ (protienuria was larger than 2.5 g/d). Results Fifteen days after treatment, the levels of proteinuria and albuminuria were significantly decreased compared with pre-treatment in PGE1 and PGE1 + ACEI groups (P<0. 01), and the therapeutic effect was better in PGE1 + ACE1 group than in ACEI group (P<0. 01). Six months after treatment, there were still significant differences in above parameters in patients with DN in stage Ⅲ and Ⅳ between PGE1 + ACEI and PGE1 groups. And for the patients in stage Ⅴ, statistic significance between pre-and post-treatment existed only in PGE1 + ACEI group (P<0. 05). but not in PGE1 and ACEI groups (both P>0. 05). Eighteen months atter treatment, the levels of proteinuria and albuminuria were significantly decreased in patients in stage HI and early stage IV in all treatment groups (P<0. 01). For patients in middle stage IV and late stage Ⅳ , the significant differences still occurred between pre-and post-treatment in PGE1 + ACEI group (P<0. 01 or P<0. 05), and were significantly better than in ACEI group (P<0. 01 or P<0. 05). However, the proteinuria of patients in late stage IV elevated in PGE1 group in post-treatment versus pre-treatment (P<0. 05). Conclusions The short term therapeutic effect of PGE1 is quick and good in patients with DN. The therapeutic effect is much better in patients in stage Ⅲ compared with stage Ⅴ. The combination of PGE1 and ACEI will get better best therapeutic effect than PGE1 or ACEI alone in long term.

Objective To investigate the effects of prostaglandin E1(PGEl)in improving proteinuria and albuminuria in the elderly people with diabetic nephropathy(DN). Methods Patients including stage Ⅲ,stage Ⅳ and stage Ⅴ were divided into four groups:conventional therapy group,PGE1 group,PGE1+ACEI group and ACEI group.Proteinuria and albuminuria were measured before and after treatment for 15 days,3 months,6 months. Results (1)In the DN patients in stage Ⅲ and stage Ⅳ (proteinuria＜2.5 g/d),the proteinuria and albuminuria descended markedly in PGE1+ACEI and PGEl group(P＜0.01).It was better than that in eonventionaI therapy and ACEI group.(2)In the DN patients in stage Ⅳ(proteinuria＞2.5 g/d),proteinuria and albuminuria were not changed significantly after 3 months and 6 months in PGE1+ACEI and PGE1 group,but they were increased in conventional group(P＜0.05).(3)In the DN patients in stage Ⅴ,the proteinuria and albuminuria were not changed much after 1 5 days,3 months and 6 months(P＜0.05).The proteinuria and albuminuria were increased by more than 10 percent(P＜0.01)in the conventional group after 3 and 6 months. Conclusions The therapeutic effects of PGE1 are obvious.Early treatment of nephropathy will get a better improvement in patients with diabetic nephropathy.

Objective To explore the relationship between insulin resistance (IR) and benign prostatic hyperplasia (BPH) in elderly men. Methods All BPH outpatients in Geriatric department of the second Xiang Ya Hospital in Feb 2008 were recruited in this study. Bioche assays including insulin (FINS), prostate specific antigen (PSA), HbAlc, fasting plasma glucose, 2 hours postprandial blood glucose were performed and HOMA-IR were calculated. The blood pressure, body weight, height and waist circumference were measured, and the body mass index (BMI) was calculated. Prostate volume (PV) was measured by abdominal ultrasound, lower urinary tract symptoms (LUTS) was evaluated by International Prostate Symptom Score (IPSS) and inquired about the history of LUTS in detail. Results (1) HOMA-IR＞ 2.8 was diagnosed as insulin resistance (IR). The patients were divided into two groups: insulin sensitivity (IS) group (n=48) and IR group (n=20). The PV level was higher in IR group than in IS group [(61.1-32. 9) ml vs. (40.4±16.5)ml, P＜0. 05], there were no statistical differences in PSA [(3.3±2.3) μg/L vs. (2.91±1.3) μg/L, P＞0.05], the history of LUTS [(13.4±6.6)years vs. (8.7±6.0)years, P＞0.05], IPSS [(16.42±6.67)scores vs. (13. 29±7.09)scores, P＞0. 05] between the two groups. (2)According to BPH progressivity evaluation provided by MTOPS study (age≥62 years, PSA≥1. 6 μg/L, PV≥31 ml), the patients were divided into two groups: low progressive risk group (n= 30) and high progressive risk group (n= 38). The FINS and HOMA-IR levels were significantly higher in highprogressive risk group than in low progressive risk group (all P＜0. 01). (3)The PV was positively correlated with HOMA-IR level and FINS level (r= 0. 431, 0. 492, P＜0. 01). Conclusions IR exists in majority of elderly BPH patients, the degree of IR and relative high level of FINS are related to the enlargement of PV and the development of BPH.

Background Conventional chemical method to fix the entire eyeball results in the edema of retinal nerve fiber layer and therefore influent the evaluation of tissue structure.Research showed that microwave irradiation can avoid this phenomenon. Objective This study was to investigate the appropriate energy and time duration of microwave irradiation for fixation of rabbit eyes specimen and compare the influence of different fixation methods on retinal structure. Methods Twenty-two New Zealand white rabbits were sacrificed by using venous air embolism.The eyeballs were enucleated from the rabbits and immersed in chemical reagents with glacial acetic acid,methyl aldehyde and chloroform for 2 days as the control group.The eyeballs were immersed in 400 ml physiological balance solution immediately,and then were fixed by microwave irradiation for 80,160,240 and 320 seconds under the lower power as the microwave irradiation groups.In the microwave irradiation+chemical fixation group,the specimens were immersed in chemical reagents for 1-2 hours after the microwave radiation.The morphology of retinal structure was examined and area of retinal detachment was calculated by hemotoxylin and eosin staining under the light microscope. Results A better fixation effect was obtained in the retinal section of microwave radiation for 240 seconds in comparison with that of the traditional chemical reagent fixation method for 2 days.The retina detachment ratio was 16.3%±11.5% for simple microwave method,50.0%±24.5% for chemical method,and 6.7%±7.8% for microwave+chemical method.showing a significant difference among 3 groups(F=32.43,P=0.000).Retinal staining was clear and retinal structure was almost normal in the specimens of microwave+chemical fixation group with 200-240 seeonds microwave irradiation and 1-2 hours chemical fixation. Conclusion Microwave irradiation method is a more ideal way for the fixation of retina because of taking short duration,lower toxicity and better staining.The combination of microwave radiation and chemical reagents can acquire an excellent quality of retinal section.

ObjectiveTo explore the effect of metabolic syndrome (MS) on the occurrence and development of benign prostate hyperplasia (BPH).Methods 101 elderly BPH patients were divided into two groups:BPH (n = 45) and BPH with MS (n= 56)group.The effects of metabolic indexes,including body mass index (BMI),waist,high density lipoprotein cholesterol (HDL-C),fasting blood glucose (FBS) and insuline resistance index (H()MA-IR),on prostate volume(PV),prostate-specific antigen (PSA),international prostate symptom score (IPSS) and lower urinary tract symptoms (LUTS) were surveyed in BPH patients.Results BPH with MS group showed significantly higher values of PV (t = 3.22,P= 0.003)and longer course of LUTS (t= 2.02,P =0.046) than BPH group.The BPH patients with overweight and obesity had significantly higher levels of PV(49.44±26.83 ml and 51.7±22.2 ml,P=0.021 and 0.043) than BPH patients with normal weight (38.10 ± 10.64 ml).Additionally,BPH patients with abdominal obesity had significantly higher levels of PV than BPH patients without abdominal obesity(50.26±26.51 ml vs.38.99± 11.25ml,P=0.005).BPH patients with low HDL-C had significantly higher PV than BPH patients with normal HDL-C[(54.23±28.92)ml vs.(40.40± 14.87) ml,P=0.009].The values of PV,PSA in the BPH patients with elevated FBS were significantly higher than in BPH patients with normal FBS (t=3.17 and 2.4I,P= 0.035 and 0.013).BPH patients with insuline resistance (IR) had higher values of PV and longer courses of LUTS than BPH patients without IR (t= 3.43 and 3.58,P-0.001).The PV was positively correlated with BMI(r= 0.459.P= O.OOO),FINS (r= 0.42,P=O.OOI),HOMA-IR (r= 0.49,P= 0.003) and gatively correlated with HDL-C (r= 0.38,P-0.000)- Multiple linear stepwise regression analysis showed that PV was closely correlated with HOMA-IR.ConclusionsMS has evident effects on the occurrence and development of BPH.

Objective To understand the elementary information and pharmacotherapy for benign prostatic hyperplasia (BPH) in outpatients in geriatrics department of three hospitals. Methods The outpatients diagnosed as BPH were investigated by daily BPH diagnosis report form, BPH medical-care requirement questionnaire, international prostate symptom score (IPSS) questionnaire and BPH quality of life scale (BPHQLS) in odd months. Results There were 657 outpatients in the three hospitals, including 456 males and 201 females. 289 patients were diagnosed as BPH, accounting for 44% of all outpatients and 63.4% of male patients. The average age of BPH patients was (77.2±5.7)years, the mean volume of prostate was (41.44 ± 21.00)ml, the median value of prostate specific antigen (PSA) was 2.24 μg/L, the mean maximum flow rate was (12. 65± 5.74)ml/s, and the average of IPSS and BPHQLS were 14.8±8. 11, 2. 56±1.36, respectively. The percentage of pharmacotherapy was 66.21% (96/145), and the rates of a-receptor blocker monotherapy and 5α-reduetase inhibitor monotherapy were 6.90% and 8. 97%, respectively. The percentage of drug combination was 26.90%. Conclusions BPH outpatients in geriatrics department of the three hospitals are at high risk, and most of them receive drug therapy. The drug choice is reasonable.
