Gastrointestinal stromal tumors are rare tumors of alimentary tract and originated from the interstitial Cajal cells,with acquired mutation of KIT(CD117).Surgery is the main therapy for resectable tumors,while imatinib,a small-molecule inhibitor of receptor of tyrosine kinase,plays an important role in treating metastatic and recurrent tumors.

Objective To investigate the prognostic factors of gastrointestinal stromal tumors.Methods From Nov.1999 to Dec.2006,a total of 85 patients were diagnosed by postoperative pathology as gastrointestinal stromal tumors.The relationship between the prognosis of GIST and demographic factors、tumor location、operation style、preoperative metastasis、lymphadenectomy、grading of Fletcher were analyzed retrospectively.Results The 1 year、3 year and 5 year survival rate of these 85 patients were 94%,60%,57%respectively,Univariate analysis indicated that tumor location、operation style、grading of Fletcher and preoperative metastasis were significant predictors of survival(P<0.05),while demographics and lymphadenectomy were not statistically related with prognosis.Multivariate analysis showed that preoperative metastasis was the independent factor predicting the prognosis(P=0.020,β=4.226).Conclusion Radical surgical excision is still the therapy of choice for primary gastrointestinal stromal tumors.Preoperative metastasis is the independent factor predicting poor prognosis,therefore early diagnosis and treatment are very important for GIST.Fletcher grading is also a simple recalls to predict the prognosis of GIST.

OBJECTIVE:To discuss the application of rational drug use software system in drug dispensing in outpatient depart-ment of our hospital. METHODS:The application of rational drug use software system (included clinical decision support soft-ware,drug dispensing software and drug management software) in prescribing (warning in advance),dispensing (intervention in the event)and the prescription review(the post review)in outpatient department of our hospital were all introduced. Outpatient pre-scription checking and intervention were collected from our hospital after the application of rational drug use software system to evaluate the effect of the software system. RESULTS & CONCLUSIONS:Rational drug use software system is adopted to realize scientific,convenient and express monitoring and management of prescription drug use in advance,in the course and afterwards. A total of 721 507 outpatient prescriptions were checked in our hospital from Jan. to May in 2015;0.17‰prescriptions were intercept-ed by system warning;system pointed out and pharmacists had checked 23.25% prescriptions;the rate of qualified prescription was more than 99.96%. After pharmacists intervention,various types of irrational prescriptions decreased significantly (P<0.01). It is suggested that pharmacists should make full use of information system,at the same time,optimize and improve the system through active exploration so as to improve rational drug use.

Objective To investigate changes of regulatory T (Treg) cell proportion and activity in patients with decompensated hepatitis B-related cirrhosis complicated with bacterial infections.Methods Thirty patients with decompensated hepatitis B-related cirrhosis complicated with bacterial infections,20patients with decompensated hepatitis B-related cirrhosis without bacterial infection and 10 healthy controls were recruited in the study from Renmin Hospital of Wuhan University during January 2009 and December 2011.Peripheral blood mononuclear cells (PBMCs) were obtained from blood samples via density gradient centrifugation.The proportion of CD4+ CD25+ CD127low Treg cells in CD4+ cells was detected by flow cytometry.The immune activity of Treg cells isolated from PBMCs was observed by a suppression assay of allogeneic mixed lymphocyte response (MLR).Results Patients with decompensated hepatitis B-related cirrhosis complicated with bacterial infections had significantly lower percentage of Treg cells in CD4 + T cells of PBMCs than the patients with decompensated hepatitis B-related cirrhosis without bacterial infections [(4.07±1.18)％ vs.(9.74 ±3.00)％,t =9.35,P＜0.01].The suppression ability to homologous PBMCs proliferation of Treg cells isolated from patients with decompensated hepatitis B-related cirrhosis complicated with bacterial infections was significantly weakened as demonstrated in MLR assay [ cpm =(22.79 ± 4.94) × 103],which had a statistical difference compared with both the patients with decompensated hepatitis B-related cirrhosis without bacterial infection and the healthy controls [ cpm =(6.43±1.19) × 103 and (5.96 ± 1.25) × 103 respectively; t =16.09 and 16.51,P＜ 0.01].Conclusion There is a decrease of both quantity and activity of Treg cell in the patients with decompensated hepatitis B-related cirrhosis complicated with bacterial infections.

Objective To study the CT and MR imaging features of skull epidermoid cyst. Methods CT and MR findings of 4 cases of pathologically proved skull epidermoid cyst were analyzed and correlated with operative and pathologic reports.Results CT and MR appearances of skull epidermoid cyst were as follows:(1)crater-form or scalloping deossification with sclerotic border and fatty density focus was detected on CT.(2)The lesions were isointense to hypointense relative to normal white matter in T1-weighted image,prominent hyperintense in T_2-weighted image,mild to moderate hyperintense in diffusion-weighted imaging(DWI),and isointense to hypointense in apparent diffusion coefficient(ADC) map on MR.Proton MRS revealed lactate(Lac)peaks at 1.3 ppm and amino acids(AAs)at 0.9 ppm. (3)No enhancement was found in substance region of all tumors on both enhanced CT and enhanced MR examinations.Conclusion CT and MR appearances of skull epidermoid cyst have unique features which are very helpful in the diagnosis of skull epidermoid cyst.

Objective To investigate the effect of transient receptor potential M4 (TRPM4) on autonomous regulation disorder of cerebral blood flow following subarachnoid hemorrhage (SAH) in rats.Methods A total of 120 clean grade male SD rats were selected.They were divided into sham operation,SAH,negative control,and treatment groups according to the random number table.The dead rats were excluded.A SAH model was induced by using the suprasellar cistern injection method with a stereotaxic apparatus.Isotonic saline 0.2 ml was injected into the rats of the sham operation group and negative control group respectively,and autologous tail arterial blood 0.2 ml was injected into the rats of the SAH group and the treatment group respectively.The isotonic saline solution was continuously pumped into lateral ventricle of rats via implantable micro-pump in the sham operation group and the SAH group respectively,and the concentration of 0.03 mol/L of TRPM4 blocking agent was continuously pumped into the lateral ventricles of rats in the control group and the treatment group respectively.The 4 groups of rats received the regional cerebral blood flow and whole cerebral blood flow detection on day 3,5,and 7,respectively.Results One hundred and six (88.3%) of the 120 SD rats survived to the time point of study,data analyses were performed in the 4 groups (with 21 rats in each group) respectively (n=7 in each time point).There were significant differences in cerebral cortex local and whole cerebral blood flow at day 3,5,and 7 in the sham operation,SAH and negative control groups (all P<0.05).Cerebral cortex local cerebral blood flow (141±18,148±24,and 168±19 PU,respectively at day 3,5,and 7) and whole cerebral blood flow (93±5,85±5,and 85±6 ml/[100 g·min],respectively at day 3,5,and 7 in the SAH group) were decreased significantly compared with the sham operation group (cortex local cerebral blood flow:235±17,220±24,and 224±20 PU),whole cerebral blood flow (141±10,147±8,and 143±8 ml/[100 g·min]),all P<0.05).Cerebral cortex local and whole cerebral blood flow (cortical local cerebral blood flow:183±26,173±26,and 187±15 PU,whole brain:114±10,104±9,and 119±5 ml/(100 g·min) in the treatment group were significantly increased compared with the SAH group (all P<0.05).Conclusion TRPM4 has an obvious effect on improving the autonomous regulation disorder of cerebral blood flow after SAH.

This study investigated the effect of epigenetic modification of maspin on extravillous trophoblastic function. The mRNA expression of maspin in placentae from normotensive and preeclamptic pregnant women was detected by RT-PCR. TEV-1 cells, a human first-trimester extravillous trophoblast cell line, were cultured and treated with CoCl(2) (300 μmol/L) to induce chemical hypoxia and with 5-aza (500 nmol/L) to induce demethylation. The mRNA expression of maspin in TEV-1 cells subjected to different treatments was determined by RT-PCR, and the proliferative and migratory abilities of TEV-1 cells were assessed by cell counting kit-8 (CCK-8) and Transwell assays. Our results showed that the maspin mRNA expression level in placentae from preeclamptic women was much higher than that from normotensive women. CoCl(2) or 5-aza could up-regulate the mRNA expression of maspin and significantly suppress the proliferation and migration of TEV-1 cells. It was concluded that the epigenetic modification in promoter region of maspin contributes to incomplete trophoblast invasion, which offers a novel approach for predicting and treating placental dysfunction.

OBJECTIVETo study the diagnosis and treatment of Müllerian duct cysts and their involvement with malignancy.

METHODSA 44-year-old male patient with papillary cystadenocarcinoma involving a Müllerian duct cyst was presented. The presentation treatment, and pathological and radiological appearances were retrospectively analysed and discussed with literature review. The main manifestation was intermittent episode of hemospermia accompanying terminal hematuria and infertility for 15 years. Final diagnosis was determined by the findings of transrectal ultrasound scan, CT scan, MRI imaging, cystoscopic examination and biopsy.

RESULTSExploratory laparotomy was performed through a suprapubic retrovesical approach. The finding that a duct-like wedge of tumor tissue passed through the prostate near cyst neck to the posterior urethra without affecting the adjacent prostatic tissue during tylectomy confirmed that it arises from Müllerian duct system. Pathohistologic examination disclosed a papillary cystadenocarcinoma and it infiltrated the wall of the cyst. Both seminal vesicles and ejaculatory duct had no carcinoma invasion.

CONCLUSIONMüllerian duct cyst involving with malignancy is exceedingly rare, the diagnosis is based on the findings of transrectal ultrasound scan, CT scan, MRI imaging, cystoscopic examination. The final diagnosis depends on the pathohistologic examination. Lumpectomy is effective and have a good outcome.
