Objective If IL-2 and IFN-? are united,perhaps we may see a more significant antitumor effect.A fusion gene of IL-2 and IFN-? was designed and constructed by DNA engineering.Methods CEA promotor、IL-2cDNA and IFN-?cDNA were obtained by PCR and RT-PCR.SDS-PAGE was used to examine the results;pcDNA-IL-2、pcDNA-IFN-?、pCEA-IL-2/ IFN-?、pEGFP-IL-2/ IFN-? were transfected to CEA high expression cell line(Lovo)by use of liposome.The fusion protein expression was examined by fluorescence microscope and Western blotting.Results IL-2/ IFN-? fusion gene can be expressed in tumor cells.Its expression is more obvious in CEA high expressed cells(Lovo),and can be located in cell plasma.Conclusion The fusion gene can be expressed in plasma of CEA high expressed cell lines.It may have a new anti-tumor effects.

The incidence of malnutrition among patients with chronic kidney disease (CKD) constantly increases despite the development of health care and dialysis techniques.New nutritional targets for CKD patients upon maintenance treatment have been developed.Before dialysis,evidences have shown that a long-term nutritional care plan,with a control of protein intake,can effectively correct metabolic disorders including proteinuria and acidosis.During the maintenance dialysis,the optimal protein and energy intakes have been recently challenged.The new classification of nutritional disorders in CKD patients may help the easily identification of protein-energy wasting.

The initiation and development of diabetic chronic complications is associated not only with the level of blood glucose,but also with the glucose fluctuation.The damage in large artery and microvessel may be caused by glucose fluctuation.There are two causes which induce glucose fluctuation in clinical:one is postprandial hyperglyceamia with not well controlled,the other is hypoglycemia causes by unsuitable therapy.A lot of effective new types of substances were applicated in clinical,such as ?-glucosidase inhibitor,glinide-insulin secretagogus,fast-acting and long-acting insulin analogues.With these new powerful tools,there is possibility to treat diabetes more correctly and safely,and control the blood glucose in a stable and good level.

Objective To explore the role of sanyrene in decreasing skin itching and observe its therapeutic effect on skin pruritus in patients with diabetes. Methods According to the principle of voluntary patients, 221 cases were divided into three groups: conventional therapy plus calamine smear including 80 cases, conventional therapy plus sanyrene including 80 cases and the conventional treatment only control group including 61 cases. Results Generalized estimating equations were established. Referring to the control group, model one was established. The coefficients in sanyrene treatment and calamine control group were 2.20 and 1.29 respectively (P<0.01). The therapeutic efficacy was significantly increased with 9.03 (OR=e2.20) times in sanyrene group and 3.63 (OR=e1.29) times in calamine group compared to the blank control,indicating effect of sanyrene and calamine were better than the control group;Referring to calamine group, Model two was established,shows better efficacy of sanyrene in calamine. The coefficients in sanyrene treatment and blank control group were 0.91 and-1.29 respectively (P<0.01). The therapeutic efficacy was significantly increased 2.48 (OR = e0.91) times in sanyrene group and 0.28 (OR = e-1.29) times in blank group compared to calamine control. Conclusions Sanyrene is effective in improving in diabetic skin pruritus situation. And compared with calamine, the treatment efficacy of sanyrene is better, which suggesting that sanyrene can be used in the clinical treatment of diabetic skin pruritus.

Objective To evaluate the effectiveness of prevention and control measures in drinking waterborn endemic fluorosis areas after water improvement in Xuchang City,Henan Province.Methods In the drinking water-born endemic fluorosis areas of Xuchang City,Henan Province,15 villages were selected based on the following parameters:the unimproved water group,the water improvement time ＜ 3 years group,the water improvement time 3-5 years group and the water improvement time ＞ 5 years group,using a multi-stage random sampling method.In those villages,the concentration of urinary fluoride was tested by the ion selective electrode method on 30 children selected by every village,and Deans method was applied for diagnosis of dental fluorosis on all students age 8-12 years old of the 15 villages.Results The dental fluorosis prevalence rates of the unimproved water group,the water improvement time ＜ 3 years group,the water improvement time 3-5 years group and the water improvement time ＞ 5 years group were 53.57％ (120/224),63.64％ (98/154),37.30％ (47/126) and 22.99％ (40/174),respectively,and the urinary fluoride geometry means were 2.10,1.30,1.07 and 1.02 mg/L,respectively.The prevalence of dental fluorosis was significantly different between the improvement time 3-5 years and the unimproved water groups (x2 =8.56,P ＜ 0.008),and between the improvement time ＞ 5 years and the unimproved water groups too (x2 =38.10,P ＜ 0.008).The geometric mean of urinary fluoride was significantly different between the improvement time ＜ 3 years and the unimproved water groups (q =5.66,P ＜ 0.01),between the improvement time 3-5 years and the unimproved water groups (q =8.14,P ＜ 0.01),and between the improvement time ＞ 5 years and the unimproved water groups (q =8.28,P ＜ 0.01).The level of urine fluoride in children was positively correlated with the fluoride content in the village (r =0.659,P ＜ 0.01),and was positively correlated with dental fluorosis index too (r =0.758,P ＜ 0.01).Conclusions The content of urinary fluoride has decreased significantly in less than three years after water improvement in drinking water-born endemic fluorosis areas.The incidence of dental fluorosis in children is related to the improvement of water supply.The longer the time of the water improvement,the more obvious the detection rate decreased more obvious.

OBJECTIVE:To study the anticoagulative and antithrombotic activity of Tongsai ruanmai tablets.METHODS:The effects of Tongsai ruanmai tablets on coagulation time, prothrombin time(PT),the fibrinogen(Fbg) content and the dissolution rate of blood clot were observed. The antithrombotic effect of Tongsai ruanmai tablets was also studied by thrombogenesis dissolution test in vivo and in vitro in rats. RESULTS: At the dose of 0.5, 1.0 and 2.0 g?kg-1,Tongsai ruanmai tablets could significantly prolong the coagulation time and PT in rats, decrease the Fbg content, increase the dissolution rate of blood clots, prolong carotid artery thrombosis formation time, shorten the length of thrombosis of rats in vitro, lessen the wet weight and dry weight of thrombosis of rats.CONCLUSION:Tongsai ruanmai tablets possess anticoagulative and antithrombotic activity.

Objective:To analyze the causes and treatment ofshallowanterior chamber in 50 patients(58 eyes)with primary angle closed glaucoma after trabeculectomy.Methods:330 cases(422 eyes)with primary angle closed glaucoma,enrolled from January 2006 to May 2009 in our hospital,were underwent trabeculectomy with application of 0.4 g/L mitomycin C once under and above sclera flap during all filtering surgeries.50 patients(58 eyes)were found with postoperative shallow anterior chamber.Results:The intraocular pressure of all patients were decreased.The incidence of shallow anterior chamber were found 50 patients(58 eyes).The causes were excessive aqueous humor filteration(29 eyes),filter bleb leaks(15 eyes),choroida detachment(5 eyes),malignant glaucoma(3 eyes).Anterior chamber reformed in 8 eyes with surgical procedure and 88 eyes without any surgical procedure.Conclusion:The incidence of shallowanterior chamber is high after trabeculetomy with application of mitomycin C in patients with primary angle closed glaucoma.Most of such cases could be reformed through conservation treatment.
