Proton beams have special physical properties, proton therapy for prostate cancer can increase the radiation dose of targets,significantly reduce the doses delivered to organs at risk, reduce the probability of normal tissue complication and secondary malignancies, improve overall survival in patients with localized prostate cancer.

Objective To evaluate the effect of microinvasive puncturatio in therapy of hypertensive intracerebral hemorrhage. Methods In 112 cases of hypertensive intracerebral hemorrhage,with CT orientation, the appropriate length of YL-1 type of intracranial hematoma puncture needle was penetrated into the hematoma. Washing, drainage and Urokinase were applied. Results 21 patients died, 91 patients' consciousness and physical function got better in 1-5 days, and 2 patients were in a vegetable state. Conclusion In therapy of hypertensive intracerebral hemorrhage, microinvasive puncturation can improve efficiency of clinical treatment, recovery of nerve function and daily living of patients,with advantages of safety,convenience,cheaper costs and minimal trauma.

Objective To investigate the effect of low intensity microwave exposure on the reproduction and offspring health of men. Method 424 married men operating radar constantly and 204 men as control were invited to complete the interview questionnaire on reproduction and offspring health. Results Incidence of abnormal sexual function in the radar group was 23.8%, while it was 14.7% in controls (P

Objective To study the changes in semen quality and levels of sex reproductive hormones in servicemen constantly exposed to radar. Method The quality of semen was analyzed with the aid of the WlTJ-9000 computer-assisted semen analysis system and the levels of sex hormones were determined with radioimmunoassay in 64 servicemen constantly exposed to radar. Results Compared to control group, semen volume, pH value, sperm density and sperm motility in radar-exposed persons were reduced. No significant difference was observed in semen viscosity, sperm viability rate, morphology, acrosomal integrity rate, and hormone levels between these two groups. Conclusions Microwave non-heating effect had adverse effect on the quality of semen, producing sub-clinical injuries.

AIM To study the effects of strophanthidin (Str) on cardiac function and Na +,K +-ATPase activity in isolated guinea pig heart failure model. METHODS Langendorff isolated heart failure models made by perfusing heart with K-H solution containing sodium pentobarbital. Eight-channel physiological recording instrument was used to determine cardiac function. Colorimetry method was used to determine cardiac sarcolemmal Na +,K +-ATPase activity. RESULTS Str increased the heart rate, left ventricular systolic pressure and the maximum rise or decline rate of left ventricular pressure in a concentration-dependent manner at 1?10 -9～1?10 -7 mol?L -1. But Str caused first a rise, then a reduction of contractility and arrhythmia accompanied by inhibition of Na +,K +-ATPase when the concentration of Str was higher than 1?10 -6 mol?L -1. Str had no obvious effect on Na +,K +-ATPase activity at 1?10 -7 mol?L -1, but increased cardiac activity at 1?10 -10～1?10 -8 mol?L -1. CONCLUSION The inotropic effect and heart toxicity of Str at higher concentration is due to inhibition of Na +,K +-ATPase, but the inotropic effect of Str at lower concentration is not the result of inhibition of Na +,K +-ATPase activity.

Spinal cord injury (SCI) occurs most often at the peak of reproduction to young people. SCI patients faced the problems how to reproduce. The development of reproductive sciences was reviewed.

OBJECTIVE To evaluate the clinical curative effect and safety of rifaximin in treating acute infectious(diarrhea).METHODS A multi-center randomized trial with double-blind double-analogue and parallel(-control) with positive drug was used.All the 240 chosen patients were classified into two groups.There were 120 cases in the trial group.On the first day,the patients received rifaximin 300mg tid.From the 2nd to 5th day,the patients(received) rifaximin 400 mg tid.There were 120 cases in the control group,on the first day,the patients received levofloxacin 100 mg tid;from 2nd to 5th day,they received levofloxacin 100 mg tid.The total therapeutic course was 3 to 5 days.RESULTS After 3-5 day treatment,symptoms such as ache in abdomen and diarrhea were(alleviated) or disappeared and stool examination was turned better or normally.To the trial group,the cure rate was 84.68%,the dominant effecive rate was 15.31%,and the total(effective) rate was 100.00%.The bacteria clearance rate was 100.00% in the trial group.There was no significant difference between two groups.There were no severe side effect in the two groups.CONCLUSIONS Rifaximin is an effective and safe drug for acute(infectious) diarrhea for adults.

Objective To investigate the expression of CD90,IGF1R in hepatocellular carcinoma.Methods CD90,IGF1R expression were detected by SP immunohistochemical staining in 36 cases of hepatocellular carcinoma,20 cases of normal liver tissue biopsied from patients of chronic cholecystitis undergoing cholecystectomy. Results The positive rate of CD90 (63.89％,23/36),IGF1R (52.78％,19/36) in hepatocellular carcinoma significantly increased (P ＜ 0.05 ); The positive rate of CD90 was higher in UICC Ⅲ - Ⅳ stage group (79.17％ ) than in UICC stage Ⅰ - Ⅱ group (33.33％,P ＜0.05) ;The positive rate of CD90 was higher in low differentiated group (76.92％ ) than in well-differentiated group (56.52％,P ＜0.05).The positive rate of IGF1R was higher in UICC Ⅲ - Ⅳ stage group (70.83％ ) than in UICC stage Ⅰ - Ⅱ group ( 16.67％,P ＜ 0.05 ). The positive rate of IGF1R was higher in low differentiated group (84.62％) than in well-differentiated group (37.38％,P ＜ 0.05 ).The expression of IGF1R was positively correlated with that of CD90 (P ＜ 0.05 ).The median survival of CD90+ patients (85 days) was shorter than CD90- patients ( 505 days ) ( P ＜ 0.05 ).The median survival of IGF1 R + patients (100 days) was shorter than IGF1 R- patients (408 days,P ＜ 0.05). Conclusions CD90 or IGF1R expression correlates positively with the progression of HCC.

Objective:To explore the relationship between the expressions of MCM5 and E2F-1 with the genesis,clinicopathological parameters of gastric carcinoma.Methods:Immunohistochemistry SP method was used to detect the expressions of MCM5 and E2F-1 in gastric car- cinoma tissues of 57 cases and in normal gastric mucosa of 20 cases.The correlation between expressions of MCM5 and E2F-1 and clinicopathological parameters of gastric carcinoma was analysed. Results:The positive expression rate of MCM5 in cancer tissues was 71.9%(41/57),while in normal mucosa it was 0(0/20).The difference between the two groups was statistically significant (P0.05).The correlation between MCM5 and E2F-1 expressions in gastric carcinoma was highly significant positive(r=0.635,P=0.000).Conclusion: Overexpression of MCM5 and E2F-1 corelates with occurence and development of gastric carcinoma.MCM5 and E2F-1 may work in the early phase in carcinogenesis of gastric carcinoma.
