Objective To explore the effect of atorvastatin in the treatment of nonalcoholic fatty liver disease and its clinical application value.Methods 110 patients with nonalcoholic fatty liver disease were randomly divided into observation group and control group,55 cases in each group.The control group was given compound dichloroace-tate diisopropylamine orally,the observation group was given atorvastatin therapy.The effects of the two groups were recorded.Results In the observation group after treatment,the alanine aminotransferase was (39.78 ±3.45) U/L, aspartate aminotransferase was (29.17 ±3.17) U/L,gamma glutamine transpeptidase was (54.28 ±4.11) U/L.In the control group after treatment,the alanine aminotransferase was (52.78 ±6.81) U/L,aspartate aminotransferase was (39.96 ±6.21)U/L,gamma glutamine transpeptidase was (68.69 ±8.31)U/L,there were statistically signifi-cant differences between the two groups(t=12.6290,11.4770,11.5273,all P<0.05).In the observation group after treatment,the triglycerides was (1.66 ±0.32)mmol/L,total cholesterol was (3.27 ±0.37)mmol/L,low density lipo-protein was (1.94 ±0.45)mmol/L.In the control group after treatment,the triglycerides was (2.38 ±0.92)mmol/L,total cholesterol was (5.74 ±1.49)mmol/L,low density lipoprotein was (3.46 ±1.17)mmol/L,there were statis-tically significant differences between the two groups(t=5.4818,11.9316,8.9925,all P<0.05).In the observation group after treatment,the ultrasonic score was (1.33 ±0.12),liver/spleen CT ratio was (0.33 ±0.08).In the con-trol group after treatment,the ultrasonic score was (1.78 ±0.35),liver/spleen CT ratio was (0.47 ±0.21),there were statistically significant differences between the two groups(t =9.0197,4.6202,all P <0.05).Conclusion Atorvastatin in the treatment of nonalcoholic fatty liver disease can effectively improve the liver function,reduce blood lipid concentration,minor adverse reactions,and it is worth popularizing in clinical use.

OBJECTIVETo measure the levels of urinary prostaglandins E2 (PGE2) in benign prostatic hyperplasia (BPH) patients with or without overactive bladder (OAB) symptoms and determine whether urinary PGE2 can serve as a biomarker for BPH-related OAB.

METHODSThis study included 86 BPH patients and 34 male control subjects without lower urinary tract symptoms. Based on the OAB symptom scores (OABSS), the BPH cases were classified as BPH/OAB (n =49) and BPH/non-OAB (n = 37) to be treated orally with tamsulosin alone and tamsulosin + tolterodine-tartrate, respectively, for 12 weeks. We measured the urinary PGE2 levels of all the subjects by ELISA before and after medication, the total PGE2 level normalized to the concentration of the urinary creatinine (PGE2/Cr). We also obtained the residual urine volume, Qmax, prostate volume, PSA level, IPSS and OABSS of the BPH patients, and compared them among different groups.

RESULTSThe baseline PGE2/Cr level was significantly lower in the control than in the BPH/OAB and BPH/non-OAB groups (both P <0.05), and higher in the BPH/OAB than in the BPH/non-OAB patients (P <0.05). After 12 weeks'treatment, the urinary PGE2/Cr level was remarkably decreased with relief of the OAB symptoms in the BPH/OAB patients (P <0.05) , but not in the BPH/non-OAB group (P >0.05). The concentration of PGE2 was not correlated with the IPSS storage score and OABSS of the BPH/OAB patients (P >0.05).

CONCLUSIONPatients with BPH/OAB have significantly higher urinary PGE2/Cr levels than those with BPH/non-OAB and normal controls, which tend to decrease with the alleviation of OAB symptoms. Our findings suggest that urinary PGE2 can be a potential biomarker for BPH/OAB.

Objective To investigate the effect of low intensity microwave electromagnetic fields (EMF) on energy metabolism of cerebral cortical neurons of postnatal rats. Methods The cultured neurons were exposed to low intensity 900 MHz continuous microwave EMF (SAR=0.38-3.22 mW/g) 2 hours a day for 4 to 6 consecutive days. The activity of cytochrome oxidase(CCO) was taken as the index for energy metabolism level. Results The results of cytochemistry showed that compared to the sham-exposed, a significant decrease of cytochrome oxidase activity in exposed neurons(0.38-3.22 mW/g P

Asthma is a chronic respiratory disease with various etiologic factors.Asthma is believed as a result of interaction between gene variation and environmental factors.Asthma increased rapidly worldwide in recent 40 years, air pollutants are believed to be the important triggers, crossover design and multi-pollutant models were used in the further studies.Although some efforts had been made in the mechanism of asthma triggers, they were limited to the lab studies.Studies in asthma related SNP and its interaction with air pollutants will be a revised method in mechanism researches.Based on epidemiological studies, in vivo and in vitro studies, the biological effects and mechanisms of air pollutants on asthma were discussed and evaluated in this paper.

Objective To evaluate a kind of operative management in the treatment of chronic non bacterial prostatitis. Methods From 1992 to 1999,cross incision of the prostatic capsule and bladder neck plasty were performed for 102 cases of chronic non bacterial prostatitis. Results The effective rate is 85.3% (87/102).It was 92.6% for the prostatitis of obstructive type (63/68) and 70.6% for patients complained of pain (24/34).43 cases have been followed up for an average of 4.5 years of which the outcome has been satisfactory in 36 and noneffective in 7. Conclusions The operative management for chronic non bacterial prostatitis is effective,safe,with less damage and less complication.

Objective To assess the urinary continence at a follow-up of 1 year after radical retro-pubic prostatectomy. Methods By using subjective (questionnaire) and objective (pad-test) methods, 165 consecutive prostate cancer patients were followed up at least 1 year. With the purpose to improve post-operative continence, surgical techniques such as preservation of external striated sphincter, preservation of bladder neck and pre-prostate sphincter (PPS), and nerve-sparing technique have been carried out.Analyses were also made in comparison by age. Results A post-operative incontinence rate of 0.7% was found in the sphincter preserving group and 5.3% in the sphincter repairing group. Patients aged 50～60 revealed a continence rate of 60% when the urethral catheter was removed, whereas 82% in the 60～70 group.After 3 months of follow-up, the continence rate of both age groups tended to be similar. Conclusions Surgical improvement and patients' age are important factors in post-operative continence after radical retro-pubic prostatectomy. The preservation of external urethral sphincter helps improve continence rate. Younger patients tend to regain to continence in a shorter period while the elders longer.

Objective To establish a new method for rapid detection of electrolytes based on micro spectrometer and dry reagent.Methods The liquid electrolyte reagent was lyophilized for the preparation of reagentin powder form,which was then sealed into a detector cup of micro spectrometer for later experiment.During determination,the detector cup,in which the specimens and diluents were added to the dry reagent,was put into the detector slot of micro spectrometer,the contents in the detector cup were then well mixed by the magnetic stirring system of micro spectrometer and incubated for 6min with the heating system.Afterwards,the A values of potassium ion,sodium ion and chloride ion were detected respectively at 620nm,405nm and 456nm following the reaction principles of turbidimetry,enzymatic method and chemical method.Based on the findings of those detections mentioned above,the performance of the electrolytic dry reagent was evaluated,and the results were then statistically analyzed.Results The linear range of each parameter could meet the demand for clinical analysis,and the dry reagents had good reaction stability for 90 days after being lyophilized,with the intra-assay coefficient variation(CV) less than 4%,inter-assay CV less than 5%,and the recovery rate from 95% to 105%.No obvious interference was observed in the determination results under the circumstance that the serum TB was less than 290.40?mol/L and the TG was less than 11.20mmol/L.The detection results by this method were well correlated with that of dry chemical analysator VITRO S-250(R≥0.98).Conclusion The method is accurate and reliable in determining the serum electrolytes,and its process is simple process and convenient to carry out.Therefore,it can satisfy the condition for field aid as well as primary care.

Objective To study the expression of MAGE-3 in colorectal cancer (CRC) with different differentiation grades. Method Immunohistochemical technique for MAGE-3 antigen was performed in paraffin embedded sections of 101 CRC specimens. The relationship between differentiation and Dukes classification of CRC and the expression of MAGE-3 antigen was analyzed. Result MAGE-3 was only expressed in tumor tissues with the total positive rate of 31.7%. The rate and intensity of MAGE-3 in poorly differentiated group were higher than that of the well differentiated group (P0.05). Conclusion MAGE-3 may be a specific molecular differentiation related marker of CRC. Its antigen may have potential use as a new peptide vaccine for immunotherapy for CRC.
