Objective To investigate the clinicopathological significance of transforming growth factor-β1 (TGF-β1), transforming growth factor-β1 receptor Ⅱ (TGF-βRⅡ ), Smad4 and Smad7 protein expressions in gastric carcinomas. Methods 109 cases of gastric carcinomas,28 of high grade dysplasia,20 of low grade dysplasia,30 of chronic atrophic gastritis,29 of intestinal metaplasia, and 21 of normal gastric mucosa were selected for the detection of the expression level of TGF-β1,TGF-βRⅡ , Smad4 and Smad7 proteins by immunohistochemistry. Results The expression of TGF-β1,TGF-βRⅡ and Smad7 proteins in gastric carcinomas and dysplasia (high and low grade) were significantly higher than those in chronic atrophic gastritis, intestinal metaplasia and normal gastric mucosa (all P <0. 001 ) ,whereas the expression of Smad4 was significantly increased in high and low grade dysplasia (cytoplas-mic IS :4.89±2.38,5.80±1.54, respectively; nuclear IS: 3.89± 1.52,3.80±1.33, respectively), and decreased in gastric carcinomas (cytoplasmic IS:2.41±2.27,nuclear IS:2.02±2. 14) (P <0.001 ,P <0.001 ,respective-ly). Meanwhile,the expressions of TGF-β1,TGF-βRⅡ and Smad7 were higher in advanced gastric cancer (4.36± 2.66,3.05±1.93,4.84±3.06, respectively) than those in early gastric cancer ( 2.93±1.85,2. 17±1.87, 4. 14±2.46, respectively) ( P < 0.01, P < 0.05, P < 0. 05, respectively ) ; however the expression of Smad4 protein was much higher in early gastric cancer (P < 0. 001 ). The expression of Smad4 protein was significantly correlated with tumor size( P < 0.05 ), lymph node metastasis ( P < 0. 001 ), T stage ( P < 0. 001 ) and chnical stage ( P < 0.001) ,and the expressions of TGF-βRⅡ and Smad4 proteins were correlated with patients' 5-year survival rate (P<0.05 ,P < 0.01 ). TGF-β1 showed the positive correlation with TGF-βRⅡ and Smad7 (r1= 0.45 ,P <0. 05; r2 = 0.49, P <0. 05), but negative correlation with Smad4 ( r = - 0.21,P < 0.05 ). Conclusion TGF-β1, TGF-βR Ⅱ, Smad4 and Smad7 protein may play an important role in the carcinogenesis of gastric carcinoma,and smad4 is the key in TGF-β pathway. Also, the detection of these proteins expression can be a useful marker for predicting the gas-tile cancer invasion,metastasis and patients' prognosis.

Aim To investigate the effects of allicin on the proliferation and apoptosis of HL-60 cells,and to explore the underlying mechanism.Methods The cell viability and colony formation were detected by MTT assay.Apoptotic cells were tested by means of TUNEL labeling.RT-PCR was used to analyze the bcl-2 mRNA expressions.Results HL-60 cell growth was significantly inhibited by allicin in dose and time dependent manners.Cell colony formation obviously decreased.The typical hypo-diploid pea J apoptotic peaJ appeared in each dose group.Apoptosis occured in a dose-dependent manner.And its later stages were identified by TUNEL labeling methods respectively,and bcl-2/bax was decreased.The expression of bcl-2 mRNA was down-regulated in a time-dependent manner after treatment with allicin at different time points.Conclusion Allicin effectively inhibits growth and induces apoptosis on HL-60 cells,which may be related with the down-regulation of expressions of bcl-2.

Two patients with coexistence of thyroid disease and suspected Gitelman's syndrome underwent SLC12A3 gene analysis. The results confirmed that both patients were compound heterozygotes of SLC12A3 gene mutation. Three novel variants of SLC12A3 were found in this study. This report suggests that Gitelman's syndrome may coexist with other disorders associated with hypokalemia, such as Graves' disease.

Objective To study the effect of multimedia on the home care to the patients with double lumen catheter.Methods Totally 100 patients with double lumen catheter for dialysis were divided into control group and observation group according to the registration order,50 cases in each group.In the control group,the home care was done to nurse the catheter and in the observation group,multimedia was used to guide home care to the catheter.The incidence of catheter-related complications was compared between two groups.Result The toal rate of catheter-related complications in the observed group was significantly lower than that of the control group (P＜0.05).Conclusion The multimedia for home care to the catheter for dialysis are easy for the patients to master so that the can change better their home care and avoid (or decrease) catheter-related complications.

Objective:To analyze the key point of client's change in counseling,and found the cognitive,emotional and other characteristics in the key point of change.Methods:Totally 14 foreign cases and 5 domestic cases with good outcome that came from the published literature in the area of assimilation model were analyzed.The secondary data analysis was used to analyze the cases'data.Results:Analysis revealed that 9 categories were generated from the data,which were understanding the causes of the problems,the accompanying feelings,the emergence of a new awareness,removing the problematic voice's threat,discovering behavior pattern,allowing the coexistence of both original conflicts,directly expressing the problematic voice desired to be expressed,viewing things with different perspectives,finding out the direction of future action.Conclusions:Behind the key point of client's change,changes in cognition could lead to changes in emotion,so that the problematic voice's threat could be removed and the coexistence of original conflict could be allowed,and then bring about the relief of the client's inner conflict.

Conclusion The content of naringin extracted with ultrasonic extraction is mo re than that with the soxhlet extraction,which be receipted in Chinese pharmeco pia. And ultrasonic extraction method is more convenient and can save time.

Objective To evaluate the clinical value of early alterations of carotid arterial intima-media thickness (IMT) and elastic function in patients with hypertriglyceridemia (HTG) using ultrasound radio-frequency technique.Methods 48 patients (triglyceride value ≥ 1.8 mmol/L) were chosen as HTG group.Quantitative intimamedia thickness (QIMT) and quantitative arterial stiffness (QAS) techniques were used to observe the alterations of carotid arterial IMT and elastic index,including diameter of carotid artery (D),distensibility coefficient (DC),compliance coefficient (CC),elasticity coefficient (α),elasticity coefficient (β) and pulse wave velocity (PWV).50 healthy subjects were recruited in control group.Differences of the above-mentioned parameters were analyzed,as well as the elastic index connections between the two groups.Results IMT,α,β,and PWV index of bilateral carotid arteries in HTG group was higher than that of the control group,while the DC and CC index was lower,and the differences was statistically significant (P＜0.05).Within the groups there were differences between the elastic indexes of bilateral carotid arteries.In control group and the HTG group:CCL＞CCR,αL＞αR,βL＞βR,PWVL＞PWVR.CC was negatively correlated to α,β and PWV (P＜0.05).Meanwhile,there was positive correlation among α,β and PWV (P＜0.05).The differences of D between two groups had no statistical significance (P＞0.05).Conclusions The abnormity of arterial occurs earlier than the morphological change,while the ultrasound radio-frequency technique can provide information of earlier alteration of common carotid arteries structure and elastic function in patients with HTG,which is a significant method of testing early alteration of carotid elastic in patients with HTG.
