Objective To discuss the application of surface anatomy scanning in the department of cerebral surgery. Methods 24 cases were examined by surface anatomy scanning.These included 5 normal cases,10 gliomas,4 metastasis tumors,3 meningiomas,1 cavernous hemangioma and 1 cerebral infarction.Results 5 normal cases with surface anatomy scanning showed excellent visualization of the sulci and gyri on the surface of the brain.In 19 cases with cortical or subcortical lesions,14 cases showed the relationship between the lesion and the brain surface structures well.5 cases could not displayed because of server edema around the lesion.Conclusion The brain surface anatomy scanning is useful for the localization of cortical and subcortical pathology,for the diagnosis of the disease of sulci and gyri,can partly replace the navigation.

Thirty-six healthy women were divided into 3 groups according to their calcium intake at week 18 of gestation. The levels of their blood calcium, phosphate, parathyroid hormone (PTH) and calcitonin were assayed during pregnancy and postpartum, and bone mineral density ( BMD) was measured postpartum. The levels of PHI and calcitonin were increasing with advancing pregnancy and reached the highest at the end of pregnancy. The women with higher calcium intake during pregnancy period had higher BMD than that of the women with ordinary diet during pregnancy period.

Objective To construct lentiviral expression vector of rat IP3R1 gene,and identify its silencing effect by using PC12 cell lines. Methods Oligo DNA sequences of 4 pairs of miRNA,named as miRNA1,miRNA2,miRNA3 and miRNA4,were designed according to IP3R1 gene sequence (GenBank:NM_001007235). The single strand of oligo DNA was annealed to form double strand DNA,and then connected with the empty plasmid pcDNA TM 6.2-GW/EmGFP-miR. By using gateway technology,the expression vector pcDNA TM 6.2-GW/EmGFP-miR-IP3R1 was linked into lentiviral destination vector pLenti6/V5-DEST to form the lentiviral expression vector pLenti6/V5-DEST-IP3R1,then it was transformed into infectious lentiviral particles and to infect PC12 cell lines. Silencing effect of gene IP3R1 was detected by Real-time PCR and Western blot. Results The sequence of expression vector pcDNA TM 6.2-GW/EmGFP-miR-IP3R1 was proved correct using sequencing method. After the transfection of letivirus vector pLenti6/V5-DEST-IP3R1 into PC12 cell lines,the IP3R1 mRNA and protein level were down-regulated 48h later,of which miRNA2 and miRNA3 sequence showed the best silencing effect,and the expression of IP3R1 in the blank control and negative control showed no significant changes. Conclusions Lentiviral expression vector pLenti6/V5-DEST-IP3R1 was constructed successfully. pLenti6/V5-DEST-IP3R1 may render the IP3R1 expression in PC12 cell lines down-regulated,and it provides a foundation for studying the function of calcium release channel IP3R1.

A 66-year-old man was admitted for a 7-day history of painful blisters and erosions in the upper lip.Real-time PCR with herpes simplex virus (HSV) type-specific primers showed that the blister fluid and crusts were positive for HSV-1,but negative for HSV-2.Observation of the blister wall with transmission electron microscopy (TEM) revealed 3 types of nucleocapsid in the karyoplast of epithelia cells,including the electron-translucent core,granular core and electron-dense core.Numerous matured viral particles with envelope were found in the cytoplasm,which were identified as HSV.The diagnosis was made as herpes simplex in the upper lip based on the above findings.PCR based molecular typing combined with observation of HSV particles via TEM may be an effective approach to the definite diagnosis of primary herpes simplex.

Objective To investigate the application of hypocaloric parenteral nutrition in postoperarive elderly patients with gastric cancer. Methods 59 elderly patients aged 60- 79 years with gastric cancer after operation were randomly assigned to receive 84 kJ · kg -1.d -1 hypocaloric parenteral nutrition (29 cases) and 126 kJ · kg-1 · d -1 standard-calorie parenteral nutrition (30cases),totally 6 d from postoperative 2 d. Complications, serum proteins, immune function,inflammation,blood glucose, liver function and recovery time of gastrointestinal function were observed during nutritional support. Results The postoperative complication rate were 37.9％(11/29) in hypocalorie group and 43.3 ％ (13/30) in standard calorie group ( P＞0.05),mainly pulmonary infection.There were no ditferences in levels of serum albumin,total protein and prealbumin between two groups at postoperative 3 d and 6 d (P＞0.05).Peripheral blood lymphocytes and T lymphocyte subsets CD3+,CD4+,CD4+/CD8- ratio were decreased after sugery,but CD8 1 values increased in two groups (P＞0.05).C reactive protein was increased significantly at postoperative 3 d compared with preoperation,and decreased at 6d than 3 d (P＞0.05).Blood glucose was decreased gradually at 3 and 6 d (P＞0.05).Postoperative liver function paraneters were elevated,no difference was found at 3 d (P＞0.05),and continued to rise at 6 d in standard calorie group than in hypocalorie group (P＜0.05). There was no difference in times of aerofluxus and cacation after operation between hypocalorie and standard calorie groups (P＞0.05). Conclusions Hypocaloric parenteral nutrition is a safe and effective method for nutrition support in postoperative elderly patients with gastric cancer.

Objective: To investigate the clinicopathologic characteristics and etiological factors of cervical cancer in young Uygur women in Xinjiang.Methods" We reviewed 350 cases of young Uygur females diagnosed with cervical cancer in our hospital during 1998-2007.The patients were divided into two groups according to their admission time (1998～2002 group and 2003～2007 group).Results: The incidence of cervical carcinoma among yong Uygur women was 12.9% in the 1998-2002 group and 10.3% in the 2003-2007 group.The first symptom was vaginal contactive bleeding.In both groups, most patients were peasants, but the percentages of highbrow was higher in the 2003-2007 group.Patients in the 2003～2007 group were of older age at first marriage and had lower rate of abortion.There was no significant difference in histological type between the two groups.However, patients in the 2003-2007 group presented with much earlier stage of cervical cancer and 56.9% of them were of stage Ⅱ disease, compared with 18.1% in the 1998-2002 group (P<0.05).Squamous cell carcinoma was the dominant histological type.Conclusion: The incidence of cervical carcinoma in young Uygur women tends to decrease due to screening and advocation of late marriage, less reproduction in remote rural areas of Xinjiang.

Objective To study imageology anatomy concerned of sellar turica and explore its potential role on growth of pituitary adenomas. Methods According to classification of sinus sphenoidalis,103 normal imageology data of sellar turica region were analyzed, including 83 cases with entire saddle type sinus sphenoidalis and 20 cases anti-saddle type sinus sphenoidalis. Furthermore, the clinical data of 45 cases of pituitary adenomas with extension into sinus sphenoidalis were retrospectively studied. Results The relationship between sellar floor's shapes and sinus sphenoidals'types was that the larger the sinus sphenoidalis was, the deeper the floor was(98.8%). The relationship between sellar floor's shapes and the superior surface of hypophysis was that most of depressed sellar floors were companied with depressed superior surfaces of hypophysises(93.8%). The anteroposterior shapes of sellar turica in midsagittal can be divided into 4 types such as bag-type, kettle-type, tube-type, and sifter-type. 45 patients suffering from pituitary adenoms with extension into sinus sphenoidalis all had entire saddle type sinus sphenoidalis. Conclusions The imageology anatomy concerned of sellar turica could explain the phenomena of pituitary adenomas with extension toward sellar floor and sinus sphenoidalis. Referring to the literatures concerned, it indicated that the imageology anatomy was the key factor of affecting the growth of pituitary adenomas.

Objective This article was aimed to take exploratory evaluation on the scientific research performance of provincial key disciplines in a medical university,and to provide a scientific basis for the discipline evaluation related topics.Methods This paper took 29 provincial key disciplines in a medical university as the evaluation system.We calculated the scientific research performance of key disciplines.Data envelopment analysis (DEA) method was used to evaluate the scientific level of performance,while the use of TOPSIS and gray correlation analysis method to rank the efficiency of its research,and the results obtained by the three methods was used for statistical correlation analysis.Results According to the results calculated by DEA Method,there were 18 DEA efficient units and 11 non-DEA efficient units.While in this 11 non-DEA efficient units,8 of them needed to reduce re source inputs and the other 3 units needed to increase research outputs.Meanwhile there were significant positive correlations between evaluation results of TOPSIS Method andGrey Correlation Analysis Method with Data Envelopment Analysis Method,respectively [the correlation coefficient:rs 1 =0.797(P =0.000); rs 2=0.583(P =0.007); rs 3-0.536(P =0.003)].Conclusions Compared to TOPSIS Method and Grey Correlation Analysis Method,DEA Method not only could evaluate the ef fectiveness of discipline,but also provide evidence to improve the non-DEA efficient units.
