Partial pancreatectomy was performed in a female patient with islet cell nodular hyperplasia, who repeatedly suffered from hypokalemia and hypoglycemia without diarrhea.After surgical operation,her symptoms were relieved.

[Objective] To observe the effect of Leweiyin of traditional Chinese compounds prescription on gastrointestinal hormones and oxygen free radicals in IBS rabbits of spleen deficiency,and to explore the possible mechanism for the treatment of IBS with spleen deficiency.[Methods] 36 two-month-old rabbits with white feather and black eyes(WHBE rabbit),half male and half female,were randomly divided into 6 groups:normal group,model group,Xiangsha Liujun pill group,Lizhu Changle group,low-dose Leweiyin-treated group,high-dose Leweiyin-treated group.Except the normal group,others were made into IBS model of spleen deficiency which was induced by damp heat stress and gavage with Fanxieye as well as method of either hunger or gorge.The drug groups were administered preventively from the medium-term of the model reproduction to the end of modeling.The rabbits of each group were observed.NO,NOS,MDA,SOD in serum and SP in colonic membrane were detected.[Results] NO,NOS,MDA in serum and SP in colonic membrane significantly more increased than the normal group(P

OBJECTIVE To investigate the clinical manifestation,diagnosis and treatment of Castleman disease(CD)in the neck. METHODS The data of 2 patients with pathological proved CD in the neck,who were seen in our hospital,were reviewed retrospectively in order to analyze their clinical manifestations,clinical and histological types, imaging characteristics and treatment. RESULTS The age of onset were 24 and 29 years respectively. Both of them only presented as a solitary,painless neck mass and met the criteria of localized CD, and also had histological evidence of the hyaline vascular variant. Complete surgical resection was the first treatment.Both of them were alive without evidence of recurrence for one year and half a year respectively. CONCLUSION CD in the neck often presents as localized lesion,which often presents as a progressive, painless, slowly growing lymph node enlargement that is generally asymptomatic. The locations most commonly are the cervical lymph nodes. CD in the neck is almost always the hyaline-vascular variant and complete surgical excision of the tumor is the best treatment.

Objective: To investigate the effects of FGFR1OP and p57/Kip2 proteins on the genesis and progression of gliomas and their clinical significance. Methods: The expression of FGFR1OP and p57/Kip2 in 54 glioma specimens was detected by SP immunohistochemical technique. The relationship between the ex-pression levels of those proteins and various clinical pathologic factors was evaluated. Results: The expres-sion of FGFR1OP and p57/Kip2 was found in 66.7% and 44.4% gliomas, respectively. The OD value of FG-FR1OP was 0.131±0.010 in high grade gliomas, and 0.118±0.010 in low grade ones, with a statistical signifi-cance (t=-5.497, P=0.000), showing that higher expression of FGFR1OP was significantly associated with glo-ma cell differentiation. The OD value of p57/Kip2 was 0.156±0.008 in high grade gliomas, and 0.165±0.006 in low grade ones, with a statistical significance (t=0.296, P=0.014), showing that lower p57/Kip2 expression was correlated with high grade gliomas. FGFR1OP was negatively correlated with p57/Kip2 in gliomas (r=-0.732, P<0.01). Conclusion: Increased expression of FGFR1OP and/or decreased expression of p57/Kip2 may play an important role in the genesis and progression of gliomas and may indicate a poor prognosis.

Objective: To study the health effects of selenium tea on cardiovascular system. Methods : Four groups of Wistar rats were fed standard diet and water, standard diet and selenium tea , high fat diet and water ,high fat diet and selenium tea respectively. Twelve weeks later, the plasma apoA , apoB, body weight, whole blood viscosity , plasma viscosity , and hematorcrit were determined while plasma fibrinogen and inhibition of erythrocyte aggregation were calculated. Results: At the end of the experiment ,the plasma apoA level of selenium tea groups was significantly higher than that of control group, while the ratio of apoB/apoA was significantly lower than that of control group. Selenium tea decreased the whole blood viscosity, plasma viscosity and inhibited erythrocyte aggregation and body weight. Conclusion: Selenium tea could significantly improve the lipoprotein metabolism and hermorrheology and decrease body weight of the rats fed high fat diet.

Objective To investigate biological characteristics of rat adipose-derived stromal cells(ADSCs) of different ages.Methods ADSCs were isolated by density gradient centrifugation from different age stages,and cultured in vitro.The adherent cells were preserved to passage,the purity of ADSCs was analyzed by immunocytochemistry method,and cell growth was observed,then proliferation capability and cell cycle were detected.Results All the ADSCs obtained from different age stages grew well and showed good morphology and growth characteristics.The proliferation rate of passage cells was higher than that of primary cells,but the proliferation activity reduced with aging,and cell cycle was prolonged.Conclusion The proliferation capability and activity of ADSCs decreased with aging.However,ADSCs of different age stages can all meet the needs of different patients for tissue engineering seed cells.

Objective:To analyse the curative effect and immune indices of tripterygium glycosides on glomerulonephritis rats . Methods:Aged Wistar rats were randomly divided into 3 groups , Group A:glomerulonephritis model rats received tripterygium glyco-sides treatment;Group B:healthy Wistar rats received no treatment; Group C: glomerulonephritis model rats received no treatment . Results:12 weeks after experiment , Group A and Group C had higher levels of 24-hour urine protein than Group B and these of pre-experiment(P<0.05).Group A had a lower level of 24-hour urine protein than Group C(P<0.05).Group A and Group C had high-er levels of TG, TC than Group B, with lower levels of ALB than Group B (P<0.05).Group A had lower levels of TG, TC than Group C, but a higher level of ALB than Group C (P<0.05).Group A had a higher rate of 0-1 grades in pathology grade than group C(χ2 =6.667,P=0.010).Group C had higher levels of TNF-αand IL-6 than Group B and Group A (P<0.05).Conclusion:Tripterygium glycosides can reduce the urine protein excretion of rats that with mesangial proliferative glomerulonephritis , rectify dyslip-idosis, raise plasma-albumin, decrease the protein expression of TNF-αand IL-6 in glomerulus.

ObjectiveTo provide evidence for the development of national norm of coping style for petrol station employee.MethodsStratified random sampling surveys and individual interview were performed in 13 269 in-service petroleum employees.Taking gender,age,education level and marriage as independent variables and coping factors as dependent variables,t test or analysis of variance was completed.Results Our data indicated that coping style was significantly changed in different gender ( P＜0.05),age (F=4.596,P＜0.05),education (F=14.723,P＜0.05) and marriage groups (P＜0.05).Conclusion Specified working environment results in corresponding coping style,and the development of national norm may be important and necessary.

Objective To investigate the expressions of Ezrin and phos-ezrin in squamous cell carcinomas (SCC),and to an alyze their clinic significance.Methods Immunohistochemistry was used to detect the expressions of Ezrin and phos-Ezrin in 20 cases of normal skin,31 cases of seborrheic Keratosis (SK),36 cases of basal cell carcinoma (BCC),and 37 cases of SCC.Results (1) The positive rates of Ezrin in normal skin (NS),SK,BCC,and SCC were 20.0％,25.8％,66.7％,and 89.2％,respectively.The positive reates of phos-Ezrin in NS,SK,BCC,and SCC were 10.0 ％,22.6％,77.8％,and 94.6％,respectively.Ezrin and phos ezrin in cancers were higher than that in noncancer tissues (P ＜ 0.01).(2) The expressions of Ezrin,and phos-Ezrin were closely correlated with the cutaneous tumor's type(R1 =0.87,r1 =0.89,P ＜ 0.01),malignant degree (patho-grading of SCC) (R2 =0.80,r2=0.86,P ＜ 0.01),metastasis via lymph node (R3 =0.89,r3 =0.91,P ＜ 0.01).Conclusions Ezrin and phos-Ezrin expressions were closely related to the types of tumor,malignant degrees,and metastasis.The combined-detection of Ezrin and phos-ezrin would provide a novel clue to predicting metastasis and prognosis of cutaneous tumor.
