Objective To explore the effect of craniotomy operation and keyhole minimally invasive opera-tion in the treatment of patients with cerebral hemorrhage .Methods 90 patients with cerebral hemorrhage were ran-domly divided into control group and observation group .45 cases in the control group were given conventional cranioto-my to clear hematoma ,45 cases in the observation group received keyhole minimally invasive operation .The operation time,blood transfusion amount , hematoma clearance rate , residual hematoma volume , GOS scale were recorded and compared between the two groups.Postoperative follow-up for one year,the rehospitalization rate,mortality,the Barthel index score,curative effect were compared .Results The operation time and blood transfusion amount of the observa-tion group were (92.5 ±18.1) min,(125.0 ±23.4) mL,which were significantly less than (125.6 ±20.3) min, (325.0 ±104.5)mL of the control group (P<0.01).And the hematoma clearance rate and the amount of residual hematoma between the two groups had no statistically significant differences (P>0.05).The effective rate of the ob-servation group(91.1%) was obviously higher than that of the control group (62.2%),the difference was statistically significant(P<0.01).The patients were followed up for one year postoperation ,the rehospitalization rate and mortali-ty of the observation group were 20.0% and 5.0%,which were significantly lower than those of the control group (42.1%,15.8%)(P<0.05).While the Barthel index score of the observation group was higher than that of the control group,the difference was significant (P<0.05).Conclusion Keyhole minimally invasive operation in the treatment of cerebral hemorrhage has good clinical curative effect ,with advantages of simple operation ,less trauma, good surgery prognosis ,which is worthy of further clinical promotion .

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.

Objective:To investigate the expression of platelet-specific alloantibody in the sera of primipara,pluripara,and recurrent spontaneous abortion (RSA) patients,and analyze the relationship between platelet-specific alloantibody and gravidity or RSA. Methods:A total of 100 primipara, 100 pluripara (gravidity≥2) and 100 RSA patients who received prenatal examination in department of aristogenesis, No. 202 Hospital of PLA from Apr 2015 to Dec 2015 were recruited. The blood samples were collected during 16-28 weeks of pregnancy, and the expression of platelet-specific alloantibody was detected by solid-phase red cell adherence assay. Results:There were 5 positive platelet-specific alloantibody in primipara group, 14 in red all pluripara group,and 26 in RSA group. Platelet-specific alloantibody was significantly associated with gravidity and the incidence of RSA (P<0.05) by chi-square analysis. Conclusion:Screening the expression of platelet-specific alloantibody during pregnancy can provide evidence for the diagnosis and treatment of RSA.

Objective To detect the levels of anti-measles antibody in a healthy population in Jin-shan District of Shanghai and to provide references for making a better immunization strategy against measles in this area. Methods Stratified sampling was used to collect 390 serum sample in 12 age groups with an equal number of males and females as well as resident and floating population. Indirect enzyme-linked immu-nosorbent assay (ELISA) was performed to detect the concentrations of IgG antibody against measles in dif-ferent groups. Results The overall positive rate and protective rate of anti-measles antibody were 78.21% and 41.28%, respectively. No significant difference in the positive rates of antibody was found between males and females, or resident and floating population (P>0.05). Antibody levels varied significantly among different age groups(χ2=191.214,P<0.01). More than 80.00% of the people aged≥1 year were positive for anti-measles antibody and the positive rates in children 3 to 6 years old and people aged ≥40 years reached 100% and over 90.00%,respectively. Infants under 8 months of age,having the lowest posi-tive rate of antibody(10.00%),were susceptible to measles. The highest protective rate was found in chil-dren aged 8 months to 9 years,followed by that in people≥40 years. Levels of anti-measles antibody in peo-ple aged 10 to 39 years mainly ranged from 200 mIU/ml to 800 mIU/ml. No significant difference in anti-body levels was found among people aged≥8 months who had different immunization histories(χ2=1.140,P>0.05). Conclusion The average level of anti-measles antibody was high in Jinshan District in 2015,in-dicating that the people in that area had a relatively high immunity to measles,but the positive rate of anti-body needed to be further improved. Infants under 8 months old and people 10 to 39 years old were the main susceptible groups. It is suggested that measles vaccination efforts should be focused on susceptible popula-tion and women of childbearing age to improve herd immunity.

Objective To investigate the factors influencing the prognosis of complex intracranial aneurysms treated with pipeline flow-directed device(PED)and to develop a nomogram prediction model.Methods The clinical data of a total of 98 patients with complex intracranial aneurysm,who were admitted to the Anyue County People's Hospital or the Second Affiliated Hospital of Guilin Medical College of China from January 2021 to April 2023 to receive PED treatment,were retrospectively analyzed.The influencing factors that might affect the prognosis of patients with complex intracranial aneurysm were collected.According to the modified Rankin Scale(mRS)score,the patients were divided into good prognosis group(being defined as mRS ≤2 points)and poor prognosis group(being defined as mRS＞2 points).The clinical data were compared between the two groups,and a nomogram model was established and validated.Results In the 98 patients,poor prognosis was seen in 10(10.20％).The differences in age,history of hypertension,history of diabetes mellitus,clopidogrel resistance,Fisher classification,repeated aneurysm rupture,aneurysm location,aneurysm size,aneurysm neck,multiple lesions,and Hunt-Hess grade on admission between good prognosis group and poor prognosis group were statistically significant(all P＜0.05).Multivariate analysis revealed that history of hypertension,clopidogrel resistance,repeated aneurysm rupture,aneurysm location,multiple lesions,and Hunt-Hess grade were the independent factors influencing the prognosis of patients with complex intracranial aneurysm after receiving PED treatment.The AUC of the nomogram model in predicting the prognosis of PED for complex intracranial aneurysms was 0.849(95％CI=0.758-0.939).The predicted curves of the model group and validation group were basically fitted to the standard curves.The results of the decision curve analysis showed that the net benefit to patients was greater than 0 when the probability threshold of the nomogram model for predicting a poor prognosis of PED for complex intracranial aneurysms was 0.10-0.90.Conclusion The factors causing poor prognosis of PED for complex intracranial aneurysms mainly include history of hypertension,clopidogrel resistance,repeated aneurysm rupture,etc.The nomogram model established in this study can predict the risk of poor prognosis in patients with complicated intracranial aneurysm after receiving PED treatment.
