ObjectiveTo investigate the pattern of the relationship of craniopharyngiomas with pituitary stalks and hypothalamus. Furthermore, based on different patterns affirmed during the operations, surgical strategies were designed for radical excision. MethodsA series of 66 patients with primary suprasellar craniopharyngiomas were treated with microsurgical techniques and the relationships of the craniopharyngiomas with pituitary stalk and hypothalamus were analyzed prospectively. Appropriate surgical approaches were selected preoperatively according to the lesion's sizes and expanding directions. The relationships of the lesions to the pituitary stalks and hypothalamus were identified in detail and dissected carefully with protection of perforating vessels. ResultsThe patterns that pituitary stalks were involved by craniopharyngiomas were identified in 36 cases and divided into four types: no relation (5 cases), adhesion (10 cases), partial invasion (8 cases) and total invasion (13 cases). The anterior floor of the third ventricle was involved in 42 cases, in which it disappeared totally in 10 cases. Total resection was achieved in 58 case, subtotal resection in 8 cases. Diabetes insipidus (DI) was identified in 44 cases postoperatively. No surgical mortality, no recurrence was found during follow-up of mean 35 months. ConclusionThe appropriate selection of surgical approaches preoperatively, careful identification and according treatment of the relationships of the tumors with pituitary stalks and hypothalamus are the keys to protect the pituitary stalk; hypothalamus in craniopharyngiomas resection in adults.

Objective To study the better way of avoidance of hypothalamus injury in surgical management of craniopharyngioma.Methods 40 cases with craniopharyngioma accepted surgery treatment were analyzed respectively.Results The pterional approach was performed in 30 cases, interfornical approach in 8 cases,subfrontal approach in 2 cases.Total removal of tumor was achieved in 35 cases,subtotal removal in 5 cases.One died from extradural hematoma after operation. No one died from hypothalamus injury.Conclusion Some way was key to avoid hypothalamus injury and to achieve a better surgical result, such as proper approach, separating strictly along tumor, identification of pituitary stalk and hypothalamus structure,preservation of perforating arteries to hypothalamus.

Objective To study the epidemiological characteristics of diabetes mellitus and to provide effective prevention and intervention methods in rural area in Kunming.Methods A cross-sectional study was conducted among 3 440 permanent residents aged 20～74 years in kunming rural districts.Results The general prevalence rate of diabetes was 4.01% and the standardized rate was 2.90%.The standardized prevalent rate for male(3.55%) was higher than that for female(2.61%),and the prevalence rates varied among different groups of rural inhabitants.Conclusion It is necessary to take effective methods to prevent and control diabetes in rural area.

Objective To study the effect of bromocriptine(BRC) on the activation of T lymphocyte stimulated by phytohemagglutinin(PHA).Methods After CD4+ T cell line Jurkat E6-1 cells were stimulated by PHA,prolactin(PRL) and BRC,respectively,the expression of linker for activation of T cells(LAT) and zeta-chain T cell receptor associated protein kinase 70 000(ZAP-70) mRNA of T lymphocytes were checked by RT-PCR.The expression of PRL mRNA of T lymphocytes was detected by Real time PCR.The expression of CD25(cluster of differentiation) as a marker of early activation on the surface of T lymphocytes was detected by flow cytometry,and the activation of nuclear factor-?B(NF-?B) was detected by luciferase reporter system.Results 1.BRC inhibited the expression of ZAP-70 as the common signal molecules both in the T lymphocyte activation pathway and PRL-prolactin-prolactin receptor(PRLR) signal transduction pathway,and decreased the expression of PRL mRNA produced by activation T lymphocytes.2.BRC enhanced the expression of LAT mRNA as another important signal molecular on the T lymphocytes and CD25 on the surface of the T lymphocytes.3.The activation of NF-?B of T lymphocytes was decreased.Conclusions BRC might inhibit the activation of T lymphocytes by inhibiting the expression of ZAP-70,the common signal molecules between T lymphocytes activation and PRL-PRL pathway,and PRL mRNA,the like-T lymphocyte growth factor.

Objective To study the conventional MRI and dittusion weighted imaging(DWI) features of Japanese encephalitis(JE)in children.Methods Sixteen patients with JE were included. Conventional MRI and DWI sequences were performed in all patients.Seven patients received MRI within 10 days of onset and 9 after 10 days.The appearances on DWI and T_2 WI were recorded.The ADC values of lesions were calculated,and then were correlated with the corresponding time interval between onset of neurological symptoms and MRI scanning.Results The lesions of JE mainly showed long T_1 and long T_2 signal intensity on MRI.The thalami were the most frequently involved areas,and 15 out of 16 showed thalamic involvement and 6 patients only showed thalamic abnormalities without other lesions.Seven patients within 10 days of onset showed lesions with high signal intensity on both DWI and T_2WI,but whole or partial lesions showed clearer on DWI than on T_2WI,and 2 patients showed extra lesions that were invisible on T_2WI.As for the other 9 patients after 10 days of onset,the lesions showed clearer on T_2WI than on DWI. There was a direct correlations between thalamic ADC values and the disease duration (r=0.84,P

Mongolian folk medicine, the important part of Mongolian medicine, is the main means, method and weapon of disease prevention, treatment and health care. Mongolian materia medicas are the important literatures of guiding the healthy development of the modern Mongolian medicine with a long and dazzling history. Since the founding of new China, a new history chapter of Mongolian folk medicine was opened under the attention and support from all levels of party and government. This paper intends to provide comprehensive insight into the rapid development of Mongolian folk medicine. The resources, phytochemistry, quality standard, pharmacology, dosage forms reform and production were reviewed to expound the process that Mongolian folk medicine was developed from traditional practices to scientific development

The purpose of this study was to develop a new way to localize the impacted canines from three dimensions and to investigate the root resorption of the adjacent teeth by using cone beam computed tomography (CBCT). Forty-six patients undergoing orthodontic treatments and having impacted canines in Tongji Hospital were examined. The images of CBCT scans were obtained from KaVo 3D exam vision. Angular and linear measurements of the cusp tip and root apex according to the three planes (mid-sagittal, occlusal and frontal) have been taken using the cephalometric tool of the InVivo Dental Anatomage Version 5.1.10. The measurements of the angular and linear coordinates of the maxillary and mandibular canines were obtained. Using this technique the operators could envision the location of the impacted canine according to the three clinical planes. Adjacent teeth root resorption of 28.26 % was in the upper lateral incisors while 17.39% in upper central incisors, but no lower root resorption was found in our samples. Accurate and reliable localization of the impacted canines could be obtained from the novel analysis system, which offers a better surgical and orthodontic treatment for the patients with impacted canines.

Objective To investigate the effect and possible signal pathway of brain - derived neurotrophic factor (BDNF) on apoptosis of rat embryo brain cells suffering from intrauterine hypoxic - ischemic injury. Methods The uterine arteries of the pregnant rats were clamped for 30 minutes in both experimental group and control group. BDNF(2 ?g) was injected into rats in experimental group while saline was injected into rats in control group through caudal veins. The samples were collected at 24, 48 and 72 hours re-spectively after artery clamping. Neuroapoptosis of different groups induced by ischemic damage was measured by TUNEL assay. The expression of extracellular signal - regulated kinase(ERK)and c - Jun - N - terminal kinase(JNK) were observed by immunohisloche-mistry.Results The number of apoptosis cells after hypoxic - ischemic injury increased progressively with time.The apoptosis cells number in experimental group were much lower in number than those of ischemic control group.The expression of ERK increased while the expression of JNK decreased in experimental group, comparing with that of the ischemic control group, with statistical signif-icance (P
