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 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 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

The incidence of systemic fungal infections have increased dramatically, moreover, drug resistance including either primary (intrinsic) or secondary (acquired) resistance, becomes one of the main reasons accounting for the failure of treating invasive fungal infections in the past decades. Nowadays, clinically available antifungal drugs are limited and their combination in antifungal therapy was not effective. It is expected to be a new strategy to synergistically sensitize antifungal drugs against drug-resistant fungi by using new small molecules. Based on the study in our research group and the reported work of others, we reviewed the research of the natural products which have synergistic effect with the antifungal agents against drug-resistant fungi. This review focused on the resource, structure, pharmacological activity, and action mechanism of the compounds, as well as somewhat in common, and would provide theoretical base for seeking new drug against drug-resistance fungi.

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.

AimTo study the effects of aspirin (Asp) and verapamil(Ver)alone or in combination on mesenteric microcirculation of rats. MethodsAcute microcirculation disturbance(AMD) was produced by highmolecular weight dextran(Mr 480, 000) 360 mg· kg-1 iv. Arteriol and venul blood flow velocity and diameter (ABFV, VBFV, AD, VD) and blood flow state(BFS) were observed by intravital microcirculation method. Results Asp 2.5, 5 mg · kg-i, Ver 0.3, 0.6 mg · kg-1,Asp+ Ver(1 + 0.15), (2. 5+ 0. 3) mg· kg-1 iv significant increase ABFV by 11.1%, 31.3%, 18.7%,19.5%, 26.5%, 37.3%, VBFV by 12.5%, 5.7%, 2.5%, 3.7%, 30%, 34.7%,AD by 4.3%, 17.9%, 31.5%, 35%, 20%, 38.1% and VDby 2.2%,4.2%, 25%, 31.5%,5.8%,23.5%espectively, and got a raise in the number of capillaries and a marked improvement of BFS. Asp + Ver(1+0.15, 2.5+0.3) mg · kg-1 iv could reverse AMD. Conclusion Asp is superior to Ver in the increase of BFV, but Ver is superior to Asp in expansion of blood vessel. Asp in combination with Ver produces marked synergistic action and protection againist AMD.

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.
