Objective To evaluate the clinical diagnosis and management of solid-pseudopapillary tumors of the pancreas.Methods A retrospective clinical analysis was made on 21 cases of solid-pseudopapillary tumors of the pancreas admitted from June 1994 to June 2003.Results Abdominal pain was the major complains in 13 cases , 7 cases had palpable abdominal mass.Imaging examination can show the abdominal mass clearly, but diagnosis can not be defined.There were 12 cases whose tumors were located in pancreatic head (4 underwent Whipple procedures and 8 tumor enucleations) and 9 cases with tumors in pancreatic tail (all underwent body and tail resection plus splenectomy).The average diameter of tumor was 9.5 cm (3-20).One case had liver metastasis.Diagnosis was proved by frozen pathology during operation in 14 cases, and other 3 cases initially diagnosed as insulinomas and other malignant tunors, had definite diagnosis by postoperative paraffin section and enzyme labeling.Enzyme labeling examinations showed that there were 14 cases of NSE positive in 15 cases, 8 cases of Vimentin positive in 10 cases and 7 cases of PAS positive in 8 cases.CK, EMA and CHG A were negative.Eighteen cases were followed up (85.7%) with a median period of 24 months(1~60) without tumor recurrence.Conclusion Huge pancreatic masses of pancreas in young females should suggest the diagnosis of solid-pseudopapillary tumors.Aggressive surgical therapy can result in good prognosis in these patients.

China Journal of Chinese Materia Medica 2005;30(22):1797-1800
Multidrug resistance of breast cancer is one of the most causes of failure in clinical chemotherapy. It is important to find out some safe and effective drugs to reserve multidrug resistance to breast cancer. The effect of some herbs had been identified in vitro. This article mainly reviewed the research progress in reversing multidrug resistance to breast cancer with Chinese herb. If the herb's effects and safety can be testified in vivo by further research, it will be effectively applied in clinic.

Objective To examine the effects of glucose on the expression of P38 MAPK and TGF?2 in cultured human umbilical vein endothelial cells.Methods Human umbilical vein endothelial cells(HUVECs)were incubated in a culture medium with 11.2 mmol/L,16.8 mmol/L and 33.6 mmol/L glucose concentrations for 24 h,48 h and 72 h respectively.The expression P38 MAPK and TGF?2 was measured by RT-PCR and Western-blot.Results When D-glucose concentrations rose,HUVECs exposed to high glucose concentration(11.2 mmol/L,16.8 mmol/L and 33.6 mmol/L)showd increase in cell expression of P38 MAPK and TGF?2 after 48 h and 72 h exposure as compared with those cultured in medium of low glucose concentration(5.6 mmol/L).ConclusionHigh concentration of glucose can arrest the proliferative response.Even a short-term exposure of endothelial cells(ECs)to high glucose concentration may lead to their activation associated with increased expression of P38 MAPK and TGF?2.High Glucose Concentration on P38 MAPK and TGF?2 expression may participate the pathogenesy of diabetic retinopathy.

Objective: To observe the clinical efficacy of electroacupuncture (EA) on Alzheimer's disease (AD). Methods: A total of 50 AD patients were randomly allocated into a Western medication (WM) group (n=25) and an acupuncture plus medication (APM) group (n=25). Patients in the WM group took oral huperzine A capsules. In addition to huperzine A capsules, patients in the APM group also received EA at Shenting (GV 24), Baihui (GV 20), Dazhui (GV 14), Fengfu (GV 16), Mingmen (GV 4) and Yongquan (KI 1). The needles on the above points were connected to G6805-Ⅱelectric stimulator [3 pairs: Shenting (GV 24) and Baihui (GV 20); Dazhui (GV 14) and Fengfu (GV 16); and bilateral Yongquan (KI 1)]. The needles were retained 25 min. The treatment was done once a day, and 10 times made up a course of treatment. The patients received a total of 3 treatment courses. There was a 3-day interval between two courses. The mini-mental state examination (MMSE) and Hasegawa dementia scale revised (HDS-R) were conducted before and after treatment. The clinical efficacies were evaluated when the treatment was completed. Results: Before treatment, there were no between-group statistical differences in MMSE and HDS-R scores (both P>0.05). After treatment, the MMSE and HDS-R scores in the APM group were significantly higher than those in the WM group (both P<0.05). The total effective rate in the APM group was 88.0%, versus 76.0% in the WM group, showing a statistical difference (P<0.05). Conclusion: EA is effective for AD and can improve clinical symptoms in AD patients.

OBJECTIVETo explore the effects of stromal interaction molecule 1 (STIM1) on the expression of apoptosis-related proteins in prostate cancer PC-3 cells.
METHODSWe transfected the lentivirus vector STIM1-pGCSIL-GFP carrying STIM shRNA into human hormone-independent prostate cancer PC-3 cells, and 3 days later observed the transfection efficiency by fluorescence microscopy. At 7 days after transfection, we determined the expression of STIM1 in the PC-3 cells by RT-PCR and Western blot and those of apoptosis-related proteins Bcl-2, Bax, survivin and activated Caspase-3 by Western blot.
RESULTSAt 3 days, inverted microscopy revealed a transfection efficiency of > 80%. At 7 days, the STIM1 expression was significantly inhibited at both mRNA and protein levels. The Bcl-2/Bax rate was remarkably decreased as compared with that of the control group (0. 31 vs 1.24 ) , and the survivin expression was markedly reduced, 0. 14 times that of the relative expression in the control. However, the Caspase-3 cleavage was significantly activated, 1.52 times that of the control (P <0.05).
CONCLUSIONSTIM1 can be regarded as an oncogene in prostate cancer PC-3 cells. Inhibition of its expression can induce PC-3 cell apoptosis by reducing the Bcl-2/Bax rate, decreasing the survivin expression, and activating the Caspase-3 pathway.

Objective To improve the diagnosis and management of solid-pseudopapillary tumor (SPT) of the pancreas. MethodsTwenty-two SPT patients were retrospectively reviewed and divided into two groups, misdiagnosed group and those with preoperatively correct diagnosis. ResultsAbout one half (46%) SPT cases were misdiagnosed preoperatively. With time SPT tends to invade its capsule resulting in impossibility of radical resection, and increased medical expenses. ConclusionsAlthough SPT is of low degree malignant, and the prognosis after surgical resection is satisfactory, misdiagnosis and preoperative misdiagnosis and inappropriate management still cost the patients increased expenses and inhospital stay.

A colistin producing strain Paenibacillus polymyxa AS1.541 was treated by N-methyl-N-nitro-N-nitrosoguanidine(NTG) for increasing yields of the antibiotic colistin.High-yield strains were obtained by selection of deregulated mutant which grow on media containing colistin,a self second metabolite,and ethionine,an analogue of methionine.Some of these mutants have higher yield of colistin than that of the parent strain.

Objective To obtain the basic growth parameters of a self-established F1 hybrid CB6F1 C57-ras transgenic mouse model, and to provide basic information for commercialization of this mouse model. Methods F1 hybrid mice (CB6F1) were produced by crossing C57-ras heterozygous transgenic (c-Ha-ras+/-) male mice and wild-type BALB/cJ female mice.The average litter size, weaning rate, sex ratio, growth performance and C57-ras transgenic positive rate were recorded and analyzed.Results The average litter size was eight, weaning rate was 90%, and sex ratio was approximately in accordance with prediction.The average body weight of newborn mice was 1.73 ±0.05 g.The average body weight of 10-week old c-Ha-ras transgenic female and male mice in CB6F1 background was 24.38 ±1.74 g and 29.42 ±1.72g, respectively, which had a significant difference (P<0.01).The c-Ha-ras transgenic positive rate was 46.9%. which was in accordance with genetic rules.Conclusions The F1 hybrid mice (CB6F1) produced by crossing C57-ras heterozygous transgenic ( c-Ha-ras +/-) male mice and wild-type BALB/cJ female mice show normal growth performance and development characteristics, and it can be used for large-scale commercial supply.
