Fouty-four patients with craniopharyngioma were admitted trom Junuary 1982 to February 1993 for post-operative radiotherapy. The 5-year survival was 78.9%. Among these 44 patients, 15 were adults and 29 were children. The children gave a higher 5-year survival rate but poorer quality of life as compared with the adults though without statistical significance in the survivals. Among the children, a dose of 56.1~60.0Gy gave better survival as compared with the 45~56Gy group without significance though causing obviously sequelae, eg: amenorrhea and hampered sex development (P

It is considered that the central nervous system (CNS) is an immunologically privileged organ, but its immunological privilege is not complete, and immunological rejection may also occurred after tissue transplantation. Neural stem cell (NSC) transplantation has developed a brand-new approach for the treatment of various CNS diseases. Despite the low immunogenicity of NSC, there are also troubles of immunological rejection. This article reviews the immunological characteristics of CNS, the mechanisms of immunological response and immunological rejection in CNS, as well as the problems of immunological rejection of NSC transplantation.

AIM: To investigate the inhibiting effect and mechanism of dimethylaminoethyl ginkgolide B mesylate on platelet aggregation and release function.METHODS: The effect of dimethylaminoethyl ginkgolide B mesylate on inhibiting PAF-induced platelet aggregation was measured by turbidimetry method through giving rabbits dimethylaminoethyl ginkgolide B mesylate at different final concentration via i.v.for 5 days.The release of Ca2 + from PAF-induced platelet in rabbits was assayed with fluorospectrophotometry and the contents of TXA2 and PGI2 were measured by radio-immunity method.RESULTS: Three groups of dimethylaminoethyl ginkgolide B mesylate (1.95,3.90,7.80 mg/kg) had significant effect on inhibiting PAF-induced platelet aggregation in rabbits (compared to normal,P

5 ml groups were 95.5% and 81.1% respectively. This difference was statistically significant (P5 ml groups were 4.5 % and 32.1%, respectively (P50 Gy was increased statistically, but the occurrence of complications was also increased. Conclusions Stereotactic radiosurgery improves the outcome of the elderly patients with brain metastases. Radiation dosage and tumor volume are significantly related with the therapeutic efficacy and the occurrence of complications.

Objective To investigate the incidence and risk factors of acute kidney injury (AKI) in patients with multiple soft tissue contusion.Methods A total of 513 patients diagnosed as multiple soft tissue contusion in the First Affiliated Hospital of Xinjiang Medical University from January 1,2008 to January 1,2013 were retrospectively analyzed.Demographics,clinical data and laboratory examinations before and after AKI were collected and analyzed.Results The age of all subjects was 31.30 (12-78) years old with the male to female ratio of 2.1∶ 1.AKI occurred in 74 cases with an incidence rate of 14.4%.No AKI was observed in patients with assault injuries,while AKI was found in 27 cases (36.5%) with car accident injuries and 4 cases (5.4%) with other injuries.AKI showed in 1 case(1.4%) with damaged area under 1%,in 4 cases(5.4%) with damaged area ranged from 1% to < 3%,10 cases (13.5%) with damaged area ranged from 3% to 5% and 19 cases (25.7%) with damaged area over 5% with significant difference among the groups (P < 0.01).Incidence rate of AKI was significantly higher in patients with chronic kidney disease (CKD) than those without CKD (54.5% vs 20.3%,P < 0.01).Two of the AKI cases died,with a mortality rate of 2.7%.Multivariate logistic regression analysis showed that the followings were the independent risk factors for the occurrence of AKI in patients with multiple soft tissue injuries:age (OR =1.996),basic serum creatinine (OR =0.976),basic evaluated GFR (eGFR) (OR =0.964),serum potassium (OR =2.117),myoglobin (OR =0.950) and damaged area (OR =1.811).Conclusions Incidence rate of AKI is quite high in multiple soft tissue contusion.Age,basic serum creatinine,basic eGFR,serum potassium,myoglobin and damaged area are the independent risk factors for the occurrence of AKI in patients with multiple soft tissue injury.

Objective To compare the clinical characteristics of community-acquired acute kidney injury (CA-AKI) and hospital-acquired acute kidney injury (HA-AKI) patients.Methods Hospital network system was employed to screen the clinical data of adult patients in the First Affiliated Hospital in Xinjiang Medical University in January to July 2013.A total of 19 528 patients were screened,and 544 AKI patients were identified based on KIDGO (Kidney Disease:Improving Global Outcomes) AKI guidelines.Three hundred and thirty patients were included in HA-AKI group and 214 patients in CA-AKI group.Clinical variables including mortality were analyzed retrospectively.Results The incidence of AKI in hospitalized patients was 2.8% (544/19 528):1.7% in CA-AKI group and 1.1% in HA-AKI group.The mean age in CA-AKI group was significantly older than that in HA-AKI group [(62.9 ± 16.8) years vs (56.6± 15.9) years].Medical patients in CA-AKI group accounted for 62.4%,and surgical patients in HA-AKI group accounted for 64.1%.The co-morbid diseases were cardiac disease,hypertension,diabetes and chronic liver disease.Majority of AKI was caused by pre-renal etiologies.The length of hospitalization was significantly shorter in CA-AKI group compared to that in HA-AKI group [12(8,20) days vs 19 (12,27) days,P < 0.01].Compared to that in HA-AKI group,all-cause mortality was significantly lower in CA-AKI group (11.5% vs 20.1%,P=0.005).Results by multivariate logistic regression analysis demonstrated that the common independent risk factors of AKI in both groups were ICU hospitalization and shock.The independent risk factor of AKI in CA-AKI group was diabetes (OR=3.019).In contrary,the independent risk factors of AKI in HA-AKI group were elderly (≥65 years) (OR=3.303),oliguria (24 h urine volume < 400 ml) (OR=6.906),use of antiinflammatory drugs (OR=13.079) and multiple organ dysfunction syndrome (OR=17.778).Conclusions The incidence of AKI in hospitalized patients is not rare,among which both communityacquired and hospital-acquired AKI are mainly caused by pre-renal etiologies.All-cause mortality is lower in community-acquired AKI compared to that in hospital-acquired AKI and the independent risk factors are different between CA-AKI and HA-AKI.

Objective To observe the effect of ginkolide B derivative(XQ) on animal thrombosis.Methods SD male rats were randomized into the model group,troxerutin(48 mg?kg-1?d-1) group,ginkolide B(7.8 mg?kg-1?d-1) group,and low-,middle-and high-dose XQ(in the dose of 3.9,7.8 and 15.6 mg?kg-1?d-1 respectively) groups.The anti-thrombotic effect of XQ was observed on rats mixed thrombosis model induced by arterio-venous shunt method and electrical stimulation.Meanwhile,ICR male mice were randomized into the model group,troxerutin(96 mg?kg-1?d-1) group,ginkolide B(15.6 mg?kg-1?d-1) group,and low-,middle-and high-dose XQ(in the dose of 7.8,15.6 and 31.2 mg?kg-1?d-1 respectively) groups.The anti-thrombotic effect of XQ was also observed on mice acute pulmonary embolism model induced by adenosine diphosphate(ADP).Results XQ at the dose of 7.8 and 15.6 mg?kg-1?d-1 decreased the dry and wet weight of the thrombosis,and obviously prolonged the formation time of rats carotid artery thrombosis as compared to the model group(P

A nd correct profile was obtained with DNA down to 125 pg.No reproducible peaks were detected with the DNA of com m on anim als and m icroorganism with the kit. For the m ale-m ale m ixture testing, average 70% of the m inor alleles were obtained when the ratios of 1∶19 and 19∶1. For the m ale-fem ale m ixture testing, results showed that the sensitivity of the kit was no compromised with the addition of fem ale sam ples. Conclusion The validation studies dem onstrated that G oldeneye?DNA ID 26Y system has good sensitivity and specificity, and suitable for m ixture testing. The polym orphism of 26 Y-STR loci included in this kit are good for forensic application.
