OBJECTIVETo compare the effectiveness and safety of transurethral resection of the prostate (TURP) and transurethral enucleative resection of the prostate (TUERP) in the treatment of benign prostate hyperplasia (BPH).

METHODSA total of 630 BPH patients with indication of surgery were randomly assigned to receive TURP (n = 305) and TUERP (n = 325), respectively. There were no significant differences preoperatively in age, prostate volume, International Prostate Symptom Score (IPSS), and Qmax between the two groups (P > 0.05). The prostate resection rate, operation time, postoperative complications, and quality of life (QOL) of the patients were recorded and statistically analyzed.

RESULTSCompared with TURP, TUERP showed a significantly higher rate of prostate resection ([47.0 +/- 13.3] vs [60.1 +/- 12.3]%, P < 0.05), shorter operation time ([57.9 +/- 15.9] vs [40.4 +/- 14.2] min, P < 0.05), and shorter bladder irrigation time ([2.7 +/- 0.6] vs [2.2 + 1.1] d, P < 0.05). Significant differences were found between the pre- and post-operative levels of serum sodium and hemoglobin in the TURP group ([141.2 +/- 3.5 ] vs [136.9 +/- 4.7] mmol/L, P < 0.01; [137.6 +/- 8.8] vs [124.8 +/- 9.6] g/L, P < 0.01), but not in the TUERP group. Three months after operation, IPSS, QOL, and Qmax were all markedly improved in both groups (P < 0.01), but with no significant differences between the two groups (P >0.05).

CONCLUSIONTUERP is better than TURP in the treatment of BPH for its advantages of higher resection rate of the prostate, shorter operation time and bladder irrigation time, less intraoperative blood loss, fewer postoperative complications, and faster recovery.

Objective: To investigate the effects of lidocaine on impairment of learning and memory function and cholinergic system caused by cerebral microsphere embolism in rats. Methods: Healthy male Wister rats were randomly divided into the following groups. (1) Control group. (2) 600 microsphere group and 900 microsphere group, in which 600 or 900 microspheres were injected into the right internal carotid artery, respectively. (3) 600 treatment group and 900 treatment group, in which 600 or 900 microspheres were injected into the right internal carotid artery, respectively, and lidocaine was given. Water maze tasks were tested for 5 consecutive days from the 7th postoperative day. The rats were then decapitated and regions of cerebral cortex, hippocampus, and striatum were selected. The activities of choline acetyltransferase and cholinesterase and the binding activity of muscarinic receptor were determined. Results: (1) The latency periods were significantly longer in the 900 microsphere group than in the control group and in the 600 microsphere group. (2) The percentages of effective search strategy were significantly lower in the 600 and 900 microsphere groups than in the control group. They were significantly higher in the 600 and 900 treatment groups than in the corresponding microsphere groups. (3) The activities of choline acetyltransferase of cerebral cortex were significantly lower in the 900 microsphere and two treatment groups than in the control group. They were also significantly lower in the 600 and 900 treatment groups than in the corresponding microsphere groups. Those of striatum were all significantly lower in the microsphere and treatment groups than in the control group. (4) The activities of cholinesterase of cerebral cortex were significantly lower in the 900 microsphere group than in the control and 600 microsphere groups. They were significantly higher in the 900 treatment group than in the 900 microsphere group. Those of hippocampus were all significantly lower in the microsphere and treatment groups than in the control group. (5) The binding activities of muscarinic receptor of cerebral cortex were significantly lower in the 900 microsphere and two treatment groups than in the control group. They were also significantly lower in the two treatment groups than in the corresponding microsphere groups. Those of hippocampus and striatum were all significantly lower in the microsphere and treatment groups then in the control group. They were also significantly lower in the 600 or 900 treatment group than in the corresponding microsphere group. Conclusion: Cerebral microsphere embolism caused significant and quantity-dependent impairment of learning and memory function and cholinergic system in rats. Lidocaine alleviated learning and memory dysfunction caused by cerebral microsphere embolism, but further inhibited the parameters of central cholinergic system.

Objective To investigate the value of fluorescin-aided confocal laser endomicroscopy (CLE) for diagnosis of helicobacter pylori (Hp) infection. Methods From June 2009 to November 2009, patients undergone gastric endoscope examination with upper gastrointestinal symptoms (upper abdominal discomfort, abdominal distension, satiation, acid reflux and eructation) or screened for gastric cancer were enrolled. The gastric mucosa CLE image data of twenty diagnosed Hp positive patients and 10 Hp negative patients was analyzed retrospectively. By comparing with histological image of targeted biopsy tissue, the CLE diagnostic criteria for Hp infection were established. In the prospective study, CLE diagnose result was compared with Hp tested result. The consistency of CLE diagnostic criteria in different observers was also analyzed. The CLE image data with histopathology result were compared accordingly. Results Total 72 patients were enrolled in the prospective study,of 34 Hp positive patients, 31 patients were correctly diagnosed by CLE. The accuracy, sensitivity and specificity of CLE diagnosis were 88.9%, 91.2 and 86.8% respectively. CLE image displaying fluorescin leakage and cell shedding was the highest specificity for Hp infection diagnosis, (97.4 %);fluorescin leakage plus gastric pits distortion and cell edema was the highest sensitivity (88. 2%). The consistency of CLE diagnostic criteria in different observers was high (Kappa value 0. 72, 0.87). The CLE image of Hp infection was highly correlated with inflammation activity (P＜0. 001). Conclusion CLE can accurately distinguish normal mucosa from Hp infected mucosa at the cellular level. The diagnostic value for Hp infection was reliable.

Abstract: Objective To understand the mental health literacy level of residents in Hainan Province, and to provide evidence for promoting mental health promotion and improving the mental health literacy level of residents. Methods Multi-stage random sampling method was used to investigate The National Mental Health Literacy Questionnaire among 6 895 residents in 12 districts including Changjiang, Chengmai, Dongfang, Ledong, Lingshui, Haikou Longhua District, Haikou Meilan District, Qionghai, Sanya, Tunchang, Wenchang and Wuzhishan. Results　In the survey 6 895 residents in 12 counties, cities, districts of Hainan Province, 365 of them reached the standard of mental health with the standard rate of 5.3%. The mental health knowledge score was (54.00±17.02) with the standard rate of 7.7%; the self-assessment score was (26.11±3.99) with the standard rate of 75.9%; the score of mental health skill was (26.22±7.25) with the standard rate of 44.8%. The mental health literacy level of medical workers was the highest, with the standard rate of 13.5% (112/830), and the mental health literacy level of farmers was the lowest, with the standard rate of 0.8% (13/1 647). The results of unconditional Logistic regression showed that the factors entering the regression model included educational background (OR=2.268), personal monthly income (OR=1.129), gender (OR=1.302), household registration (OR=0.776), and whether they had participated in mental health related courses OR training (OR=0.511). The higher the educational background and personal monthly income, the higher the psychological quality. The mental health of women was higher than that of men, and that of urban was higher than that of rural, and those who had participated in mental health related courses were higher than those who had not. Conclusions The mental health literacy level of Hainan residents is at a low level, and the influencing factors are multifaceted. It is suggested to strengthen the mental health monitoring comprehensively and carry out rich health education service mode for different groups.

OBJECTIVETo explore the value of percutaneous radiofrequency ablation (PRFA) combined with transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the management of recurrent small hepatocellular carcinoma.

METHODSBetween March 2001 and March 2005, 52 patients with recurrent hepatocellular carcinoma (tumor size< or =5 cm) underwent PRFA, and 14 of the patients (tumor size 3-5 cm) also received TACE and PEI, and their clinical data were analyzed retrospectively.

RESULTSMRI or CT after PRFA revealed complete coagulative necrosis of the tumor in 38 cases (tumor size <3 cm). In the 14 patients (tumor size 3-5 cm) with also TACE and PEI, complete necrosis occurred in 11 cases (78.6%). In the patients involved in this study, the 1-, 2-, 3- and 4-year survival rates were 96.2%, 69.4%, 45.5% and 30.0%, respectively.

CONCLUSIONSPRFA is an effective modality for local treatment of recurrent small hepatocellular carcinoma, capable of total elimination of tumors <3 cm. For tumors of 3-5 cm, combination with TACE and PEI may help increase the tumor necrosis rate following the ablation and raise the patients' survival rate.
