Objective To evaluate the effect of simvastatin and atorvastatin on clinical progression of benign prostatic hyperplasia (BPH) in elderly patients with metabolic syndrome (MS).Methods A total of 135 patients with BPH and MS aged 60 years and over were divided into three groups:simvastatin group (n=45,40 mg/d),atorvastatin group (n=45,20 mg/d) and control group (n=45).BMI,waist circumference,blood pressure,levels of fasting blood glucose (FBG),glycosylated hemoglobin (HbA1c),triglyceride (TG),total cholesterol (TC),low-density lipoprotein-cholesterol (LDL C),high sensitivity C-reactive protein (hs-CRP),interleukin 6 (IL-6),testosterone,estradiol,prostate specific antigen (PSA) and international prognostic scoring system (IPSS) and prostate volume were detected before and 12 months after treatment.Results Compared with control group,patients receiving simvastatin or atorvastatin for 12 months showed that the levels of serum TC,TG,LDL-C,hs-CRP,IL-6,IPSS were decreased(all P＜0.05),the level of serum HDL-C level were increased (all P＜0.05),and prostate volume was reduced(P＜0.05).The decrease in prostate volume was more in patients receiving simvastatin than receiving atorvastatin [(10.86±5.65) ml vs.(5.91 ± 3.03)ml,P＜0.05].Multiple stepwise regression analysis showed that the reduction of prostate volume was positively related to the decreases of serum TC and IL-6 levels,and to the increase of serum HDL-C level.Conclusions Simvastatin and atorvastatin have the efficacy reducing prostate volume and improving obstruction symptoms of lower urinary tract,and slowing the clinical progression of BPH and simvastatin is more effective than atorvastatin on reducing prostate volume.The efficacies of statins might be through lowering cholesterol level and antiinflammatory effect.

Objective To improve the preoperative diagnosis accuracy of cerebellopontine angle tumors through analyzing MRI findings. Methods Ninety-six cases with cerebellopontine angle tumors, confirmed by pathology and surgery, were collected and underwent MRI scan plus enhanced MRI. Among the 96 capes, we observed acoustic neurinoma in 55 cases, meningioma in 20 cases, cholesteatoma in 9 cases, trigeminal neuroma in 7 cases,cavernous hemangioma in 3 cases,arachnoid cyst in 2 cases. The MRI characteristics of all cases were analyzed retrospectively. Results The chief type of tumor happened in the cerebellopontine angle zone was acoustic neurinoma,followed in order by meningioma,cholesteatoma,trigeminal neuroma,cavernous hemangioma and arachnoid cyst. The accuracy of preoperative localization and qualitative diagnosis were 100% and 94.7%respectively.Conclusion MRI has a high value in the diagnosis and differential diagnosis of cerebellopontine angle tumors,which can be used as a preferred preoperative examination method in cerebellopontine angle tumors.

Objective To investigate the effects and significance of neuronavigation and electrocorticography monitoring in resection of eloquent brain glioma. Methods Thirty-six cases with intracranial tumors accepted microneurosurgery resection under neuronavigation and electrocorticography monitoring. The clinical data and postoperative outcome were analyzed. Results The mean registration error was (2.0 ±0. 5)mm in all operations and all skin flaps and bone windows designed by neuronavigation could fit the operation demands. Total resectin of the tumor was achieved in 31 cases and subtotal resection in 5 cases. Neurological symptoms improved and no severe complications or death happened in all patients. Conclusion Neuronavigation combined with electrocorticography monitoring can accurately locate the eloquent glioma and retrieve the brain shift. This method is a real-time technique and has functional test ability. It can improve the total removal rate and decrease the mortality and disabled rate.

Objective To investigate psychological health status and its change in short term among persons bit by dogs.Methods Psychological health status was evaluated with patient health questionnaire (PHQ-15) Chinese version for the 613 wounded persons bit by dogs,including 368 males and 245 females with average age of 36 years plus or minus 14 years (standard deviation),meanwhile their wounds were handled routinely at clinics,as well as health education and cognitive psychological intervention were provided for them.Results All of the 613 persons with dog bites had mild or moderate somatic syndrome in their initial visits and 478 of them (78.0%) still presented mild somatic syndrome and only 23 (3.7%)with moderate symptoms four week after dog bites by PHQ-15 scores.One hundred and fifty-two of 613 (24.8%) followed-up at their initial visits had depressive symptoms,which could remain in 61 of them (10.0%) four weeks after bites.Two hundred and eighty-four of them (46.3%) had anxiety symptoms at initial visits,and 258 (42.1%) still had mild and nine (1.5%) had moderate symptoms four weeks after bites.Conclusions Psychological symptoms were popular in wounded persons by dog bites,which can persist for a certain time.PHQ-15 can be used for evaluating their psychological status.

Objective To investigate the effect of hyperphosphatemia on type Ⅱa sodium dependent phosphate cotransporter (NaPi-2)mRNA expression in the kidneys of 5/6 nephrectomized (STNx)rats and evaluate the interference of Renagel. Methods Forty-two male Sprague-Dawley rats underwent 5/6 nephrectomy or sham operation. The animals were then divided into seven groups: (1)STNx+high-Pi diet(HP) group (1.2%P); (2)STNx+low-Pi diet(LP) group(0.2%P); (3)STNx+ normal-Pi diet (NP) group; (4)STNx+HP+Renagel-treated (Ren)group; (5)sham+HP group; (6) sham+LP group; (7)sham+NP group. Serum ionized calcium (iCa) , phosphorus, and iPTH levels were detected at day 2,7,14.The kidneys were removed after the rats were sacrificed on day 14 and serum 1,25-(OH)2D3 and FEp were measured. RT-PCR was applied to examine NaPi-2 mRNA. Results Serum P and iPTH levels in STNx+HP group were significantly higher than those in STNx+ LP and 3 sham groups (P0.05)among these five groups mentioned above. Serum P and iPTH levels in Renagel-treated group were much lower than those in STNx+HP group (P

0.05).In the group with primary common bile duct suture,the occurrence of bile leakage was relative with hyperglycemia(P0.05).Conclusion It is the key factors,including chosing appropriate patients, intraoperative special examination, careful manipulation and effective medical treatment that can reduce the morbidity of bile leakage.
