Fifty-five patients with brain lesions were treated with gamma knife combined with stereotaxic technique. There were 33 males and 22 females, and their age ranged from 12 to 72, averaged 41 years. The lesions were located in the sellar area in 21 patients, in the deep cerebrum in 10,in the basal ganglion in 9, in the cerebellum in 5, in the brain stem in 4. Intracranial multiple lesions were found in 6 patients. Twenty-four patients were treated with gamma knife combined with stereotaxic biopsy, 21 with gamma knife combined with stereotaxic aspiration for the cyst and 8 with gamma knife combined with stereotaxic biopsy and aspiration. In the other 2 cases, conservative therapy was used because their pathogenesis was parasite and abscess. Of the 47 biopsies, glioms were diagnosed pathologically in 15 cases, metastasis in 9, craniopharyngioma in 7, pituitary adenoma in 4, germinoma in 3, other tumor in 4, parasite in 1 and abscess in 1. The biopsy positive rate was 93.6%. Aspirated cytic fluid ranged from 1 to 30ml, and the symptoms improved dramatically after aspiration. There were no severe complications and deaths related to stereotaxic procedures. It suggested that gamma knife combined stereotaxic technique is a useful and safe procedure for neuropathological diagnosis and an appropriate management for certain brain lesions.

Objective To investigate physical activity in patients with type 2 diabetes mellitus and to analyze its influencing factors,in order to provide references for the prevention and control of disease.Methods A total of 469 cases of patients with type 2 diabetes mellitus were enrolled in this study.The basic information,such as gender,age and so on,and situation of physical activity,including work,housework,transportation and entertainment,were surveyed via questionnaire.Results The total amount of physical activity of patients with type 2 diabetes mellitus in this survey was (1 581.59±743.65)MET-min per week,were mainly contributed from entertainment and housework which was (940.83 ± 547.06) and (407.20 ± 226.63)MET-min per week respectively.The amount of physical activity of patients in different age,occupation,duration of illness and BMI,and patients with or without other chronic diseases were significantly different (P＜0.05).Under 45 years old,being on-the-job,with other chronic disease were risk factors for lack of physical activity in patients with type 2 diabetes mellitus (P＜0.05),while aged 45-＜60 years old,light or normal weight was the protection factors of sufficient physical activity in patients with type 2 diabetes mellitus (P＜0.05).Condusion The overall physical activity of patients with type 2 diabetes mellitus is on the medium level,and its main types are entertainment and housework.Patients under 45 years old,being on-the-job,with other chronic diseases have higher risk of lacking physical activity.

In recent years , fungal biofilms related infection have become an increasingly important clinical problem .Many clinically important fungi can form biofilms , including:Candida albicans , Cryptococcus neoformans , Rhodotorula species , Aspergillus fumigatus, Malassezia pachydermatis, Histoplasma capsulatum.Many chronic persistent infections are associated with the fungal bio-film formation.The developmental phases of fungal biofilms are complicated , including adhesion, colonisation, maturation and dispers-al, which are governed by many genes .This review discusses clinical impact of biofilm formation of the common human pathogenic fun -gi, biofilm structure and the molecular mechanisms during the biofilm formation process .

Background and purpose: Primary intracranial epithelioid haemangioendothelioma (EH) was rare. This study was to discuss the clinical pathological features, radiographic findings, treatment and prognosis of primary intracranial EH combined with literature review. Methods: We reviewed a case of EH reported from our hospital, and comprehensively analyzed the related literature. Results: Based on our report and review of the literature, EH is rare and with borderline or uncertain behavior. The original tumors demonstrated specific image features. The tumor usually appeared as a small nest or cords composed of eosinophilic epithlioid or spindled cells.Immunohistochemical assay were positive for endothelial markers CD31, CD34 and FⅧ. EH may be treated with complete surgical resection whenever possible and is sensitive to radiation. The EH has a favorable prognosis. Conclusion: EH has variable malignant potential, and should be differentiated from meningioma. Total resection and close follow-up is recommended. Additional radiotherapy is advised for residual tumors.

Objective To explore the clinical efficacy of Baihu decoction combined with insulin on type 2 diabetes with acute hyperglycemia patients.Methods A total of 86 cases of type 2 diabetes with acute hyperglycemia patients were randomly divided into experimental group (n=43) and control group (n=43).Two groups of patients underwent conventional exercise and diet adjustment intervention, control group was treated with insulin, continuous injection of 14d, experimental group was treated with Baihu decoction based on control group, 7d was taken for one courses, two course in all.The clinical symptoms of the two groups were compared, and the FPG, 2hPBG, HbAlc levels was detected in two groups pre-and post-reatment, the serum IL-6, hs-CRP, TNF-α, LP, APN, Cor were detected by enzyme linked immunosorbent assay method.Results The total effective rate was 91.7%in experimental group, higher than 76.7% in control group(P<0.05).After treatment, FPG, 2hPBG, HbAlc, IL-6, hs-CRP, TNF-αlevels in two groups were all significantly decreased (P<0.05), and those indexes in experimental group were significantly lower than those in control group (P<0.05).After treatment, APN and LP were significantly decreased, Cor was significantly increased in two groups(P<0.05), and the LP and APN in experimental group were significantly lower and Cor was significantly higher than that in control group (P<0.05).Conclusion Baihu decoction combine with insulin can significantly improve the clinical symptoms in type 2 diabetes with acute hyperglycemia patients, reduce the level of blood glucose and cytokines, and its mechanism may be relate to the increase APN level, reduce the LP and Cor levels.

Objective To investigate the effects of recombinant human granulocyte colony stimulating factor (rhG-CSF) therapy on pulmonary hypertension,and its influence on number and functions of circulating endothelial progenitor cells (EPCs) in rats.Methods Eight week old Sprague-Dawlay rats were randomized into model group,treatment group and control group (8 rats in each group).The rats in model group and treatment group were treated with single subcutaneous injection of 1％ monocrotaline (50 mg/kg) to induce pulmonary hypertension models,while the control group was treated with phosphate buffered saline.Five days later,the rats in treatment group were administrated with 50 μg/(kg· d) rhG-CSF for 3 days.On day 21,peripheral blood was collected from caudal vein in all groups,and the percentage of EPCs in 100 000 mononuclear cells was evaluated by flow cytometry.Right ventricular systolic pressure was assessed,and the pathological changes of lung tissue and pneumoangiogram were observed by HE staining.Meanwhile,peripheral mononuclear cells collected from caudal vein were separated and cultured in vitro for EPCs.The cell ffunctions as proliferation,adhesion and migration ability were assessed.ANOVA and LSD test were applied as statistical analysis methods.Results (1) The right ventricular systolic pressure of rats in model group was higher than that in the controls [(48.13 ± 2.85) mm Hg vs (27.88 ± 3.04) mm Hg,t=2.016,P＜0.01],the lesion of endothelial cells in pulmonary arteriolar was evident,and the vessel wall was thickened.The pulmonary artery pressure of rats in the treatment group [(30.38 ± 2.83) mm Hg] was lower than that in the model group and close to the level of control group (t=0.376,P＞0.05) with mild pulmonary pathological changes.(2) The percentage off peripheral blood EPCs in mononuclear cells in the model group was decreased as compared to the control group [(0.016±0.007) ％ vs (0.031±0.011) ％,t=2.617,P＜0.01].After administration ofrhG-CSF,the EPCs in treatment group [(0.042±0.013) ％] was increased evidently as compared to the model group (t=4.325,P＜0.01) and the control group (t =1.942,P＜0.05).(3) The proliferation,adhesive and migrated cells of EPCs in model group were 0.49 ± 0.04,(6.93 ± 1.47) cells/HPF and (7.22±1.53) cells/HPF,lower than those in control group [0.68±0.07,(11.05±1.73) cells/HPF and (12.58±2.15) cells/HPF] and treatment group [0.63±0.06,(12.35±1.82) cells/HPF and (12.97±2.84) cells/HPF],the differences were statistically significant(all P＜0.05).Conclusions rhG-CSF may be effective in treating pulmonary hypertension through up-regulating the number and function of circulating EPCs in rat model of pulmonary hypertension.

Objective To study the MRI signs of primary central nervous system lymphoma(PCNSL).Methods MRI features of PCNSL in 44 patients proven by pathology from January 2004 to September 2005 were analysed retrospectively.There were 29 men and 15 women,the age ranged from 12~76 years old with mean 53.Results The lesions localized at brain in 41 patients and spinal cord in 3.The lesions were multiple and single.The lesions were hypointense on T1WI and isointense or hyperintense on T2WI mostly.Nearlly all the lesions had parenchymatously massive or nodular enhancement,the minority has ring-like enhancement post contrast-enhanced scan.Conclusion PCNSL has certain MRI characteristic.The solitary or multiple lesions with obviously nodular enhancement,especial contact with cerebrospinal fluid space,the possibility of PCNSL diagnosis should be consider.

Objective Candidas rank as the second factor of deep fungal infection .This study aimed to investigate the rela-tionship between Candidas and melanin by screening clinically isolated melanin -producing Candidas . Methods We incubated 360 strains of clinically isolated Candidas with caffeic acid , DOPA agar , and minimal medium at a temperature of 35℃, with Cryptococcus neoformans as the positive control .We observed the changes in the culture media using transmission electron microscopy (TEM) and electron spin resonance ( ESR) spectroscopy . Results Cryptococcus neoforman produced pigmentation in all the three types of medi -um.At 5 days, a standard strain of Candida albicans SC 5314 turned dark brown in the DOPA agar and minimal medium and , at 10 days, 12 and 15 of the 360 Candida strains turned dark brown in the DOPA agar and minimal medium , respectively, which were not shown to be melanin by TEM and ESR spectroscopy . Conclusion Culture media are not reliable enough for the identification of mel-anin-producing Candidas , and the observations need to be further verified by TEM and ESR spectroscopy .
