OBJECTIVE To investigate the epidemic situation of vertical dissemination of the Escherichia coli(ECO) and Klebsiella pneumoniae(KPN) isolates producing extended-spectrum beta-lactamases in the hospital.METHODS The fingerprints of the isolates were obtained by pulsed-field-gel-electrophoresis(PFGE),and were analyzed with software Quantity One.RESULTS The similarity of 10 isolates and 7 isolates among the 21 ECO(isolates) from ICU was more than 90%,and 100%,respectively;the similarity of 3 KPN isolates was 100%.The similarity of 9 isolates among the 20 ECO(isolates) was more than 90% and the similarity of 4 isolates among the 6 KPN isolates was more than 90% in the neurosurgery ward.The similar coefficients of 3 isolates and 2(isolates)(among) the 10 ECO isolates from the ward for cadre were more than 90% and 100%,(respectively.) The similar(coefficients) of 2 isolates among the 7 ECO isolates from the gastroenterology ward and 2(isolates)(among) the 18 ECO isolates from the respiratory ward were more than 90%.The isolates whose similarity was more than 90% were also found in other wards.CONCLUSIONS There are vertical disseminations of single clone of ESBL-producing organisms in several wards,especially in the ICU.It is necessary to strengthen the management of(infection)-control.

Background and purpose:Glioblastoma is one of the most common intracranial tumors, the morbidity and mortality are both high, and the molecular biological mechanism of the disease is still unclear. In this study, we detected the gene expression of tyrosine kinase receptor (TKR) pathway in primary glioblastoma(GBM) with low-density array, furthermore we analyzed the significance of the gene expression change. Methods:We detected 26 genes of RTK pathway in 10 primary GBM tissues and 9 normal brain tissues (gained from the decompression operation of brain trauma), and analyzed the different expressions of these two kinds of tissues by statistic method.Results:The Ct values of MAP2K1 and MAP2K4 in normal brain tissues were 1.6?1.7 and 2.2?2.1, the Ct values of MAP2K1 and MAP2K4 in primary GBM tissues were 3.9?1.5 and 5.0?2.0, and the Ct different values between normal brain tissues and primary GBM tissues of both genes were -2.3 and -2.8(P

Objective To investigate the therapeutic effects of botulinum toxin type A (BTX-A) in elderly patients with primary intractable trigeminal neuralgia.Methods 27 elderly patients with primary intractable trigeminal neuralgia were treated with BTX-A local multiple point injection.The efficacy was assessed by visual analog scores (VAS) before and 1 week,2 weeks,1 month,3 months and 6 months after the treatment.Results VAS scores was (9.2±1.1),(5.8±3.0),(3.6± 2.3),(2.3±2.3),(3.2±2.9) and (4.6±3.2) before and 1 week,2 weeks,1 month,3 months and 6 months after BTX-A treatment respectively.VAS score was gradually decreased,reached the lowest at 1 month after BTX-A injection,and then was gradually increased.There were significant differences in VAS scores between between pre-and post-treatment (P＜0.05).The efficiency was 37.0％,85.2％,92.6％,70.4％ and 59.3％ at 1 week,2 weeks,1 month,3 months and 6 months after the treatment respectively.There were significant differences in efficacy between different time points after the treatment (all P＜0.05).3 patients had the transient numbness of mouth askew and incomplete eyelid closure and recovered spontaneously after 4-8 weeks.No severe adverse effects were found in the other 27 patients.Conclusions BTX-A is safe and effective in the treatment of primary intractable trigeminal neuralgia in elderly patients.

Objective To measure the expression of hypoxia-inducible factor (HIF)-1α in acral malignant melanoma (MM) tissue and to investigate its relationship with the stem cell factor (SCF)/c-kit pathway.Methods Immunohistochemical staining was performed to measure the expression of HIF-1α in tissue specimens from lesions of 93 patients with acral MM,21 with non-acral MM,39 with acral melanocytic nevi,and from the normal acral skin of 15 healthy human controls.Meanwhile,the expression of c-kit was detected by immunohistochemical staining in the 93 acral MM tissue specimens.Statistical comparisons were carried out by chi-square test and Mann-Whitney U test.The relationship of HIF-1α expression with c-kit expression as well as tumor progression and staging was assessed by Spearman correlation analysis.Results Immunohistochemistry showed that the expression rate of HIF-1α was 87.10％ (81/93) in acral MM specimens,90.48％ (19/21) in non-acral MM specimens,15.38％ (6/39) in acral melanocytic nevus specimens,but 0 (0/15) in the normal acral skin specimens.The expression of HIF-1α was significantly higher in acral MM lesions than in normal acral skin and acral melanocytic nevus lesions (both P ＜ 0.01),and significantly different between acral MM and non-acral MM lesions (P ＜ 0.01).Moreover,HIF-1α expression was positively correlated with Clark level and Breslow depth of melanoma (rs =0.442,0.368,respectively,both P ＜ 0.01),with the progression of acral MM (from in situ to aggressive and metastatic MM) (rs =0.420,P ＜ 0.01),and with the expression of c-kit (rs =0.307,P ＜ 0.01).Conclusions HIF-1α is highly expressed in acral MM,positively correlated with the staging,progression and aggression of MM,and co-expressed with c-kit in acral MM tissue,suggesting that both HIF-1α and c-kit take part in the pathogenesis of acral MM.

Objective To investigate clinicopathological features、diagnosis and surgical treatment of duodenal stromal tumors. Methods A retrospective clinical analysis was made in 23 cases of duodenal stromal tumors admitted from 1995 to 2004. Results Melena and abdominal pain was the most common presenting symptom. Complete resection was achieved in all cases, including pancreatoduodenectomy in 13 cases, by pylorus-preserving pancreatoduodenectomy in 3 cases, and tumor enucleation in 7 cases. The mean size of the tumor was 6. 6 cm (2 - 21 cm) , among them 10 cm in 6. Pathologically tumors less than 5 cm were all of potential malignancy, whereas those larger than 5 cm were malignant. Follow-up of 2 months to 9 years found all cases alive and healthy except for one who died of liver metastasis one year postoperatively. Conclusion Duodenal stromal tumors were low malignancy tumors. Aggressive surgery is the choice of treatment. Favorable prognosis is expected after complete surgical excision.

Objectives To investigate the role of lymphangiogenesis in the perineural micrometastasis of pancreatic adenocarcinoma. Methods The clinical data of 30 pancreatic adenocarcinoma patients who were admitted from Sep. 2005 to Oct. 2006 for extended radical surgery were collected. The samples including pancreatic cancer, adjacent tissue, lower bile duct, pancreatic tail, the structure surrounding the SMA (peripancreatic nerve plexus) and lymph nodes were collected during operation. They were subjected to conventional pathological examination. The lymphatic capillaries weredetected by double immunohistochemical staining and the lymphatic vessel density ( LVD) was measured. Results Intra-pancreatic and/or peripancreatic neural invasion was observed in 25 patients (83. 3% ) , of which 20 were found to have both the peri-pancreatic and intra-pancreatic neural invasion. The other 5 only had the intrapancreatic neural fiber invasion and there was no single patient with peri-pancreatic neural fiber invasion only. Peri-neural invasion was not significantly associated with patients' age, gender, lymph node metastasis, tumor size and the location (P > 0.05) , but was obviously associated with JPS clinical staging ( P < 0. 05 ). The mean intratumoral LVD was (4.2 ±3.4) per field, which was significantly lower than (11.3 ±6.9) per field of adjacent tissue and (10.8 ±4.4)per field of normal pancreatic tissue(P<0.01). The mean intratumoral LVD between adjacent tissue and normal pancreatic tissue was not statistically different. Lymphatic vessel invasion was observed in non-malignant tissues in 18 patients, and there was a distribution correlation between lymphatic vessel invasion and extra-pancreatic neural plexus invasion (P<0.05). Conclusions The incidence of peri-neural invasion was high, peri-neural invasion was associated with JPS clinical staging and lymphatic vessel invasion, which suggested the possibility of the cancer spreading by peritumoral lymphangiogenesis route into the peri-SMA neural plexuses.

Objective To observe the effects of functional ambulation training in a realistic environment based on the activities of daily living among stroke patients with hemiplegia.Methods Thirty-two stroke survivors with hemiplegia were randomly divided into an experimental group and a control group,each of 16.Both groups were given routine rehabilitation training,while the experimental group was additionally given functional ambulation training based on the activities of daily living in a realistic environment for 60 min per day,five days a week for six weeks.Both groups were evaluated using the mini-mental state examination (MMSE),the Holden walking functional class assessment (HWFCA),the Berg balance scale (BBS),functional gait assessment (FGA),the 5 times sit to stand test (FTSST),the timed up and go test (TUGT),and rated using the specific activity balance confidence scale (ABC) and the modified Barthel index (MBI).Results Before the training,no significant differences between the two groups were found in terms of any of the measurements.After the six weeks of training,significant improvement was observed in all of the outcome measures except the MMSE and the HWFCA,with the experimental group scoring significantly better,on average,than the control group.Conclusion When combined with routine rehabilitation training,functional ambulation training based on the activities of daily living in a realistic environment can significantly enhance the functional gait,balance and postural control of stroke survivors.This should facilitate their activities in daily life and improve their confidence in maintaining their balance.

Objective This study is about to detect the KCNJ5 gene variations in aldosterone-producing adenoma (APA) with primary hyperaldosteronism (PA),and to investigate the association of the KCNJ5 gene missense mutations with APA and PA.Methods A total of 46 APA tumors and their clinical characteristics were collected from Hypertension Center of the People's Hospital of Xinjiang Uygur Autonomous Region,and all the tumors were confirmed by pathology.All the samples of the coding region segments of KCNJ5 were detected by PCR and direct DNA sequencing to compare the different missense mutations in the tumor cells and peripheral blood cells and to analyze the association between the genotype and phenotype.Results Three missense mutations were found in 46 patients with APA:c.451G ＞ C/A (p.G151R) (5/46),c.503T ＞ G (p.L168R) (4/46),c.830T ＞ A (p.S209T) (12/46).S209T,as an unreported somatic mutation was observed.There were no missense mutations detected in the peripheral blood.Sex,age,systolic blood pressure,diastolic blood pressure,duration of hypertension,plasma potassium,urine potassium,aldosterone,plasma renin activity,aldosterone,and plasma renin activity ratio,as well as the rate of positive family history were compared between the mutants and wild-types.Systolic blood pressure and plasma potassium level among G151 R,L168R,and S209T had statistical differences.Systolic blood pressure in G151R was significantly higher than the other two groups,while the plasma potassium level was significantly lower than the other groups.Conclusions Three missense mutations were found in 46 patients with APA.The subjects with mutations had more serious condition than those without mutations after comparing their clinical phenotype.Besides,other different subtypes may exist in PA.
