Objective:To investigate the clinical efficacy and safety of PCNL with the use of different percutaneous renal access in treatment of renal calculi.Methods:Percutaneous renal minimal access(F14～F16)or small access(F18～F20)was established randomly in 142 patients,and PCNL were performed in all patients.The clinical parameters including operative time,complication and stone-free rate were compared in the two groups.Results:The operative time of simple renal calculi were(78.3?15.6)min and(91.2? 18.2)min(P0.05)in small access group and minimal access group respectively.The operative time of complicated renal calculi were(115.3?20.1)min and(130.7?28.7)min(P

The main reason of recurrence and metastasis in breast cancer is the resistance for the radiotherapy and chemotherapy,and the mechanism of radio-resistance and chemo-resistance may be related to the DNA damage response (DDR).There is a complicated system of the DDR pathway,including cell cycle checkpoint,DNA repair,transcription and apoptosis to maintain the integrity of cell genes.In the cancer treatment,DDR occurs in various kinds of cytotoxic drugs and radiation to cause genetic damage,which limits the curative effect of chemotherapy and radiotherapy.This promotes the targeted therapy of DDR pathway,especially checkpoint kinase 1 (CHK1).Recently,the new viewpoint supports that CHK1 is a main marker of the DDR pathway activation,which shows that CHK1 not only activates the check point but also affects the DNA repair and apoptosis directly.Thus,the role of CHK1 in DDR will promote CHK1 inhibitor to be one of the new treatment strategies for the cancer patients who resist the radiation and chemotherapy.

Angiocentric Glioma has been newly identified as an epilepsy associated tumory. Up to now, reported cases are still scarce. The tumor causes drug-resistant epilepsy. On histological findings, monomorphous bipolar tumor cells are arranged around vessels. Imaging studies show that the tumor is diffused or rimlike hyperintensity on T1-weighted SE sequences and a stalklike extension to the ventricle on T2-weighted sequences. The World Health Organization listed this new entity in its fourth edition of the WHO classification of tumors of the central nervous system published in 2007.

Objective To learn about the mastery level of midwives and obstetric nurses about fetal monitoring knowledge.Methods 77 midwives and obstetric nurses attending a fetal monitoring education programme in Huaxi Second Hospital of Sichuan University were investigated by using a self-made questionnaire.Results Some respondents lacked of systematic training in fetal monitoring knowledge,and they could not accurately answer the purpose or contents of fetal monitoring,as well as the basic elements and related knowledge about fetal electronic monitoring.Most of the respondents focused on fetal monitoring in clinical practice,but neglected the corresponding frontier progresses.Conclusions The training and education on fetal monitoring knowledge should be strengthened to improve obstetric quality because of the unsatisfactory survey results in midwives and obstetric nurses.

Objective:To investigate the airborne pollen concentration in Beijing city during autumn and to grade the Artemisia pollen concentration .Method:Burkard volumetric trap was used to sample the airborne pollen in Beijing city from August 1st 2007 to October 10th 2007. Patients only allergic to mugwort pollen were followed up, and their symptom scores and the mugwort pollen concentration were analyzed statistically.Result:①Mugwort and Humulus(including Cannabis Sativa L) were the main airborne pollen during August and September in Beijing city, accounting for 31% and 51%,respectively; ②Mugwort pollen season was from 8th August to 8th October;③The daily peak concentration of Mugwort pollen was 267 g/m~3,with an average of 71 g/m~3,the daily peak concentration of Humulus pollen was 672 g/m~3,with an average of 124 g/m3;④88.5% out-patients suffering from hay fever or asthma during Autumn were allergic to mugwort, 28.2% allergic to Humulus;⑤the grading of airborne Mugwort pollen concentration: 0～14 g/m~3 as grade 0, 15～40 g/m~3 as grade Ⅰ, 41～116 g/m~3 as grade Ⅱ,more than 117 g/m~3 as grade Ⅲ.Conclusion:It was the first time that Burkard volumetric sampler was employed in monitoring Mugwort and Humulus concentration in Beijing city. Average concentration of mugwort pollen was about 100 g/m~3, and concentration grade Ⅲ of mugwort pollen was distributed during the last ten days of August and the beginning of September.

Objective To explore the clinical efficacy of tirofiban in treatment of patients with high-risk non-ST-segment elevation of acute coronary syndrome (NSTE ACS),in order to improve the level of treatment effect. Methods 90 cases with high-risk NSTE ACS from January 2011 to April 2013 were randomly divided into control group and observation group. The control group were received treatments of conventional aspirin,clopidogrel, anticoagulation,coronary angiography (CAG)and percutaneous coronary intervention (PCI),while the observation group were added tirofiban therapy an the basis of control group. After the treatment,the differences of cardiovascular adverse events,thrombolysis in myocardial infarction (TIMI)flow grade and complications in both two group were observed and compared. Results There were significant differences in major adverse cardiovascular events in the distal vascular blockage,surgery without reflux,recurrent angina and myocardial infarction and post-PCI TIMI flow grade 2 and 3 (P<0.05),but not in bleeding complications,TIMI flow grade 0 and 1 before and after PCI treatment. Conclusion Tirofiban is safe and effective in treatment of high-risk NSTE ACS in interventional procedures. It can improve TIMI flow, increase tissue perfusion and reduce postoperative complications.

Objective To explore types and risk factors of recurrent ischemic stroke in ischemic stroke patients using antiplatelet drugs. Methods By retrospective study, 130 recurrent ischemic stroke patients using antiplatelet drugs (antiplatelet therapy group) and 101 recurrent ischemic stroke patients not taking antiplatelet drugs (non antiplatelet therapy group) were collected. Two groups of patients were divided according to the ischemic subtypes, and risk factors between different subtypes were analyzed. Results (1) Single factor analysis showed history of coronary heart disease and smoking are more frequent in antiplatelet therapy group with recurrent lacunar infarction (LI). History of coronary heart disease, diabetes, and high level of low density lipoprotein (LDL) are more frequent in antiplatelet therapy group suffer from recurrent atherosclerotic thrombosis (AT). (2)Logistic regression analysis showed the history of coronary heart disease , smoking are independent risk factors for recurrent LI in antiplatelet therapy group (P = 0.018, P = 0.027); history of coronary heart disease, diabetes, and high level of LDL are independent risk factors for recurrent AT in antiplatelet therapy group (P =0.003, P = 0.010, P = 0.002). Conclusions The history of coronary heart disease and smoking are independent risk factors for the recurrence of LI in patients with antiplatelet therapy. History of coronary heart disease , diabetes , and high level of LDL are independent risk factors for the recurrence of AT in patients with antiplatelet therapy. Combined coronary heart disease would increase both LI and AT recurrence.

Purpose:To study the effect of interferon-? on the growth of human cervical cancer transplanted subcutaneously in nude mice.Methods:Twenty-eight nude mice transplanted subcutaneously with human cervical cancer were divided into 4 groups: control group,positive control group(DDP group),IFN-? low dose group(1.5?10 7 u/kg) and IFN-? high dose group(3.0?10 7 u/kg). Different drugs were used from day 14 after transplantation and all mice were sacrificed after 49 days. The weight of the mice and the volume of tumor were measured. FCM was used for measuring the proportion of cell cycle S+G 2 -M(%) in tumor cells. Results:The growth inhibiting rates in DDP group,IFN-? low dose group,IFN-? high dose group were 92.8%,73.8% and 93.1% respectively. Except for mice in DDP group,there was obvious increase in the weight of mice in other three groups. As for the proportion of S+G 2 -M(%),there was no difference in control group,IFN-? low dose group and IFN-? high dose group. Conclusions:IFN-? can inhibit markedly the growth of transplanted cervical cancer,which is correlated with the IFN-? dose. The mechanism of IFN-? inhibiting cervical cancer was not due to the suppression of cancer cell proliferation.
