Objective To investigate the mechanism by which epidermal growth factor (EGF) accelerates the growth of estrogen-negative breast cancer cell line MDA-MB-435S. Methods Under the effect of EGF cyclin D_1 was measured by Western blot and cell-cycle was assayed by FCM. Results EGF enhanced cyclin D_1 expression. Protein kinase C (PKC) inhibitor Go6976 blocked cyclin D_1 over-expression caused by EGF. In EGF group G_0/G_1 was 69.36%, phase S was 22.77% and PI was 0.31. Differences were all significant compared with control (P

Objective: To investigate the effective of Sanhua decotion(三化汤) on early brain water content,penetration of blood brain-barrier and the expression of aquaporin4(AQP4) in rats with acute cerebral ischemia/reperfusion(I/R).Methods: The string inserting method was employed to reproduce the rat model of focal cerebral I/R SD rats were randomly divided into sham operation group,model group and Sanhua decotion group.After I/R,each group was then divided into 6 hours,12 hours,24 hours,48 hours and 72 hours five subgroups.The brain water content was detected by the ratio of wet/dry weight to evaluate cerebral edema and the blood-brain barrier(BBB) damage was observed by Evan′s blue(EB) staining.The AQP4 mRNA and protein expressions were measured by reverse transcription-polymerase chain reaction(RTPCR) and immunohistochemistry respectively.Results: Compared with sham operation group,the brain water content,EB content,AQP4 protein and AQP4 mRNA expressions were increased at every time point after I/R in the model group(P

Objective To evaluate the clinical application of partial splenic embolization in the treatment o hypersplenism caused by schistosomiasis. Methods Twenty four patients with hypersplenism caused by schistosomiasis were treated with peripheral partly splenic embolization with gelf.oam. The counts of white blood cell(WBC) and platelet (PLT) were compared between pre-and post-splenic embolization. Results The extent of splenic embolization were 50% - 75%(mean 59.24%) with post-therapeutic follow-up of 6 months ~ 2 years, showing significant increase of WBC count with preoperative, peak and the latest follow-up counts as (2.15?0.67)?109/L, (12.36?3.24)?109/L and (5.65?1.38)?109/L respectively(t = 11.08, P

Objective To understand the compliance of antihypertensive drug use in patients with hypertension.Methods A retrospective analysis was conducted among 218 patients with hypertension to understand their drug use compliancy and influencing factors,including side effect of the drugs,drug type,educational level,economic status and drug use length.Results The factors including disease course,drug type,drug use length and drug side effects,the economy status,educational level,awareness of hypertension related knowledge and psychological reaction could significantly influence the compliance of antihypertensive drug use.Among the patients surveyed,86.67％ of them with poor drug use compliance had only an educational level less than senior high school,77.33％ had poor awareness of hypertension related knowledge.Conclusion The antihypertensive drug use compliance in patients with hypertension is directly related to the outcome of the disease in clinical treatment.It is necessary to take effective measures to improve the treatment compliance and maintain normal blood pressure level of the patients.

OBJECTIVETo improve the clinician's awareness of angiostrongyliasis.

METHODSThe clinical and laboratory data as well as the epidemiological information concerning 18 patients with eosinophilic meningoencephalitis caused by Angiostrongylus cantonensis were analyzed.

RESULTSAll patients had a history of eating raw fresh water snail (Ampularium canaliculatus) before the onset of the disease. Incubation period ranged from 1 to 25 days. The major symptoms of the patients had severe headache and pain in the trunk and limbs. Increased eosinophlic count in peripheral blood and cerebrospinal fluid was noted. Tested by enzyme-linked immunoadsorbent assay (ELISA), sera were specifically IgG-antibody positive against Angiostrougylus cantonensis antigen, but were negative against other parasitic antigens such as Paragonimus westermani, Cysticerus, Cellulosae hominis, Echinococcus granulosus and Trichinella spiralis. Abnormal spotty signals were found in 2 cases with brain magnetic resonance imaging. Electroencephalogram (EEG) showed slow alpha rhythm. All the patients were effectively treated with combined administration of albendazole and dexamethazone.

CONCLUSIONSAngiostrongyliasis is one of the common causes leading to eosinophilic meningoencephalitis. To our knowledge, Wenzhou is the first small outbreak site of angiostrongyliasis discovered in Chinese mainland.

Objective To systematically evaluate the efficacy and safety of duloxetine and sertraline for Chinese depression patients.Methods The randomized controlled trials(RCTs)comparing the efficacy and safety of duloxetine and sertraline in the treatment of depression were retrieved from databases and the quality of literature was evaluated.Meta-analysis was performed with the software Revman 5.2.Results Eighteen RCTs involving 1 557 Chinese depression patients were included.The results of Meta-analysis showed that there were no significant differences in efficacy and cure rate between duloxetine and sertraline groups(OR=1.28, 95%CI:0.94 -1.73, P =0.11; OR =1.25,95%CI:0.97 -1.62,P =0.09, respectively).The Hamilton Depression Scale(HAMD)scores were significantly lower in duloxetine group than those in sertraline group at 1,2 weeks after treatment;however,there were no significant differences at 8-weeks after treatment between duloxetine and sertraline groups.The score of Medical Outcomes Study Pain Measures(MOSPM)in duloxetine group was significantly lower than that in sertraline group(P<0.01). The rate of insomnia in duloxetine group was significantly lower than that in sertraline group(RR=0.57, 95%CI:0.32 -1.00, P=0.04).There were no significant differences in other common side reactions between the two groups(P>0.05).Conclusions Duloxetine has similar long term treatment effect as sertraline,but it has a rapid-action profile.Duloxetine is more effective than sertraline in depression with painful physical symptoms;besides,duloxetine is less likely to induce insomnia.
