AIM:To explore the clinical therapeutic effect and safety of cervical cancer treated with neoadjuvant chemotherapy with gemcitabine hydrochloride.METHODS:60 patients with cervical cancer were randomly divided into the intervention group(30 cases) and control group(30 cases).The intervention group were treated with neoadjuvant chemotherapy with gemcitabine hydrochloride and cisplatin,the control group were treated with mitomycin and cisplatin.The status of clinical symptoms,size of tumor,side effect of chemotherapy and postoperative pathological analysis were observed and compared.RESULTS:Comparing the re- sults of two groups of patients,the intervention group was significantly higher than control group(P

Sterol 14alpha-demethylase (CYP51), the most widely distributed member of the P450 superfamily, is the key enzyme in sterol biosynthesis pathway. CYP51 is not only an important model for fundamental P450 structure/function studies, but also an important target protein of cholesterol-lowering agents, antifungal drugs and herbicides. This article reviewed the research advances in CYP51 at various aspects, including sequence characteristics, physiological roles, catalytic properties in vitro, protein structure, structure-function relationships and inhibition of CYP51. The problems remained in current research and designations of CYP51 inhibitors are also discussed.

ObjectiveTo elucidate the effect of portal decompression and FK506 (FK) pretreatment on porcine extended hepatectomy.MethodsForty pigs were equally devided into 4 groups. Group A underwent 80% hepatectomy and portacaval shunt with FK pretreatment, group B did 80% hepatectomy and portacaval shunt, group C did 80% hepatectomy and FK pretreatment and group D did 80% hepatectomy. ResultsThe 5 day survival rate in Group A and B was 80% and 60% respectively, higher than 30% in Group C and 20% in group D ( P 200 mm H 2 O ( P

OBJECTIVETo compare the changes of diagnosis, treatment and control of 0-14 years old urban asthma children during 10 years.

METHODThe questionnaires were given to diagnosed asthmatic children during the national epidemiological survey of asthma in children in 2000 and 2010 to understand the diagnosis and treatment of asthma and the status of the disease control. Children with asthma of a total of 36 cities were involved in this study, and the diagnosed asthma children in recent 2 years were 6,128 and 8 174, separately. Data were stored using epi-info software by double entry, V19.0 of SPSS was used to do the statistical analysis , χ(2) test was used.

RESULTThe proportion of correct diagnosis of asthma before investigation in 2010 was 64.6%, while it was 70.7% in 2010, which showed a significant increase (χ(2) = 59.3, P < 0.01). Diagnosis rate of asthma onset within 1 year was separately 50.8% and 78.6% in 2000 and 2010. The early diagnostic rate was significantly higher in 2010 than that in 2000 (χ(2) = 817.7, P < 0.01). In 2000 and 2010 children with asthma medication in the use of inhaled corticosteroids was 36.3% and 61.7%, it increased by 0.7 times in 2010 (χ(2) = 907.5, P < 0.01). Systemic corticosteroids utilization rate was separately 74.2% and 39.1% (χ(2) = 1 730.6, P < 0.01). Beta 2 agonists utilization rate was separately 71.8% and 73.4%, showing a slight rise (χ(2) = 4.3, P < 0.05). Antibiotics usage was separately 97.4% and 76.0%, compared to a decrease of 21.4% (χ(2) = 1 274.2, P < 0.01). In the survey of 2000 and 2010, children with acute asthma attacks within recent 1 year were separately 86.3% and 77.0% (χ(2) = 194.0, P<0.01), hospitalizations for asthma attack were separately 54.0% and 47.3% (χ(2) = 61.7, P < 0.01), rate of absence from school due to asthma less than 10 days was separately 47.5% and 71.4% (χ(2) = 682.6, P < 0.01).

CONCLUSIONThe rates of correct diagnosis and early diagnosis of asthma in urban Chinese children within 1 year had a significant increase compared with a decade ago. Inhaled corticosteroids therapy had increased by 0.7 times than before while systemic corticosteroids utilization rate significantly decreased. Antibiotics usage had a decrease of 22.0% but they were still overused. Asthma control was significantly improved, but acute exacerbations and hospitalizations of asthma children still accounts for a large proportion although they both had a great improvement.

OBJECTIVETo investigate whether the impairment of grafted liver after transplantation was induced by the same inflammatory cells in cold and warm ischemia.

METHODSMale SD rats were divided into two groups randomly, 24 grafted livers in each group were stored for 120 or 240 min at 4 degrees Centigrade Ringer's solution. Also male SD rats were divided into three groups, in which 24 grafted livers in each group were experienced warm ischemia ranged from 90, 120 to 150 min from non-heart-beating donor. The recipients were killed after 1, 3, 6, and 24 hours of transplantation for sample collection.

RESULTSAlong with the prolongation of cold and warm ischemia time, the serum ALT and AST levels were increased gradually after transplantation. Light microscopy showed some necroses in hepatocytes after 3 and 6 hours of transplantation in cold ischemia, and some neutrophilic infiltration in sinusoids. There were a large number of hepatocytes necroses after 3, 6 hours of transplantation in warm ischemia from non-heart-beating donor and a lot of lymphocytic infiltration in sinusoids. The findings in electron microscopy were as the same as those found in light microscopy, and the lymphocytes which infiltrated in sinusoids in warm ischemia were identified as T lymphocytes in electron microscopy.

CONCLUSIONSThe impairment of grafted livers after transplantation seems to be induced by two different inflammatory cells in cold and warm ischemia, that is, neutrophils mediate the cold ischemia-reperfusion, and T lymphocytes mediate the warm ischemia-reperfusion from non-heart-beating donor.

OBJECTIVES: Existing evidence suggests that miscarriage and stillbirth are associated with an increased risk of stroke in women. However, the impact of these events on stroke mortality remains unclear. This study aimed to elucidate the potential association between miscarriage and stillbirth and stroke mortality in women. METHODS: We employed a competing risk model using data from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial to assess the relationship between miscarriage/stillbirth and stroke death. Death from other causes was considered as a competing risk, and we conducted a subgroup analysis to explore the potential impact. RESULTS: Our study included 68,629 women for miscarriage and 65,343 women for stillbirth. No significant association was observed between miscarriage and stroke mortality (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.84 to 1.10; p=0.58). While a single stillbirth did not show a significant association (HR, 0.81; 95% CI, 0.57 to 1.15; p=0.23), recurrent stillbirth (≥2) was associated with a significantly increased risk of stroke mortality compared to women with no stillbirths (HR, 2.24; 95% CI, 1.45 to 3.46; p<0.001). CONCLUSIONS Our findings suggest that recurrent stillbirth, but not single events, is associated with an elevated risk of stroke mortality in women. Further research is warranted to clarify the underlying mechanisms and potential long-term health implications of recurrent pregnancy loss.
