Objective To compare the clinical efficacy and safety of continuous subcutaneous insulin infusion (CSII) and multiple subcutaneous insulin injection (MSII) in elderly patients with severe type 2 diabetes.Methods Thirty-seven elderly patients with severe type 2 diabetes in the hospital intensive care unit (ICU) were divided into observation group (19 cases) and control group (18 cases) by random number table method.The observation group was treated with continuous subcutaneous insulin recombinant human insulin lispro injection,and control group was treated with recombinant human insulin lispro injection before meals and at bedtime routine insulin glargine subcutaneous injection.Two groups of patients and their families were given diabetes education.Changes in blood glucose,insulin dosage,blood glucose control standard time,rate of hypoglycemia and hospitalization time between 2 groups before and after treatment were compared.Results After treatment,fasting blood glucose in observation group was (7.2 ± 1.2) mmol/L,2 hour postprandial blood glucose was (9.4 ± 1.2) mmol/L,bedtime blood glucose was (9.4 ± 1.3) mmol/L; which in control group was (8.5 ± 3.0),(10.0 ± 2.4),(10.2 ± 2.4)mmol/L respectively.Fasting blood glucose,2 hour postprandial blood glucose and bedtime blood glucose significantly decreased after treatment in two groups,but there was significant difference between 2 groups (P ＜ 0.05).Blood glucose control standard time in observation group was (5.4 ± 2.5) d,insulin dosage was (43 ± 9) U/d,in control group was (12.8 ± 3.8) d,(55 ± 10) U/d respectively,and there was significant difference (P ＜ 0.05).Observation group had no hypoglycemia.Conclusion CSII for elderly patients with severe type 2 diabetes has better curative effect and security than MSII,and is more conducive to the control of blood glucose and the improvement of the condition.

Objective To eukaryotically exp ress B7.1 extracellular domian and investigate its biological activities. Methods Recombinant expression vector pDisplay/B7.1(V+C) wa s transfected into Hela cells by electroporation method. The expression of B7.1( V+C) was identified by immunohistochemistry and in situ hybridization, respectiv ely. In vitro T lymphocyte activation activity was detected by 3H-TdR incoporation method and the aroused cytotoxicity after mixed culture of pDispla y/B7.1(V+C) transfected Hela cell-T cell was observed by MTT method. R esults B7.1(V+C) was expressed successfully on the surface of Hela c ells. The expressed B7.1(V+C) was able to activate T lymphocytes in the pres ence of anti-CD3 monoclonal antibody. Cytotoxicity could be observed when pDisp lay/B7.1(V+C) transfected Hela cells were mixed and co-cultured with T lymphocy tes. Conclusion Eukaryotically expressed B7.1(V+C) main tains its T lymphocyte costimulatory activity, and B7.1(V+C) can be adopted to construct bifunctional molecules for tumor immunotherapy.

The TNA mRNA expression in 33 samples of cervical carcinoma and 28 samples of condyloma have been observed by using ~3H and Digoxigenin labeled TNF—? cDNA probes and in situ hybridization technique, we found that the results of in situ hybrdfzation with these two kinds of labeled probes were alike, the sensitivity with ~3H labeled probe was slightly higher than that with Digoxigenin labeled probe. Nevertheless, the nonisotope probe would be used more and more in future because of its safety, rapidity and convenience in work.

Total body fat of 12 male adults were measured by ordinary and modified water displacement method repeatedly. The mean value was 9.37 kg calculated by ordinary method.It was significantly lower than that of 10.07 kg calculated by modified method (p

Objective o observe the therapeutic effects of suspension-assisted functional rehabilitation training of motor function for patients with cerebral infarction. Methods Ninety-six patients with cerebral infarction were divided randomly into a treatment group and a control group. All patients were given routine medical treatment and routine limb movement therapy. Those in the treatment group also used an electrically-driven suspension device to aid in their functional rehabilitation training. The patients were assessed with a simplified Fugl-Meyer Motor Functional Assessment (S-FMMFA), and using the Postural Assessment Scale for stroke patients ( PASS), the Barthel Index (BI) and the 6-minute walking distance test before and after treatment and at a 6-month foliowup. Results The average S-FMMFA, PASS, BI and the 6-minute walk results in the treatment group were all significantly better than those in the control group. Conclusions Suspension-assisted training can significantly help improve limb movement function and ADL performance in cerebral infarction patients.

Purpose To explore the role of histone H2B monoubiquitination in primary colonic carcinoma and clinicopathological pa-rameters of colonic carcinoma. Methods To detecte the expression of histone H2B monoubiquitination in 116 cases of primary colonic carcinoma and 15 cases of normal colonic mucosal tissue by avidin-biotin-peroxidase complex ( ABC)-immunohistochemistry. Results The level of histone H2B monoubiquitination was significantly reduced in poorly differentiated colonic carcinoma 19. 4% (6/31) compared with that of well-differentiated colonic carcinoma 49. 4%(42/85), moderately differentiated colonic carcinoma 49. 4% (42/85) and normal colonic mucosal tissue 86. 7% (13/15) (P<0. 05). The expression of histone H2B monoubiquitination was closely correlated with tumor differentiation, Dukes stage, TNM stage and lymph node metastasis (P<0. 05), but not depended on sex or age (P>0. 05). Conclusion Histone H2B monoubiquitination is obviously associated with the progression of primary colonic carcinoma. Although its specific mechanism still remains unclear, histone H2B monoubiquitination could be a novel potential molecular marker for early diagnosis, clinic treatment and prognosis evaluation.
