ObjectiveTo explore the influence of 3C bolus wizard on postprandial glucose levels in diabetic patients. MethodFifty-eight patients with type 2 diabetes in our hospital were monitored with continuous glucose monitoring system(CGMS), continuous subcutaneous insulin infusion(CSII)and CareLink(3C for short)for 6 days.The function of “3C” bolus wizard was applied during treatment and all the patients were given dietary nursing and health education.The glucose level was observed.ResultThe level of P2hBG of the 58 patients was between 6.4~10.7mmol/L in 3~6 days.ConclusionsBolus wizard plays an important role in “3C” treatment.It can make the postprandial glucose of patients satisfactorily controlled in a short time only to avoid insulin hypoglycemia because of large doses of insulin.At the same time,health education on patients can achieve remarkable results as well.

China Journal of Endoscopy 2016;22(8):57-60
Objective To evaluate the effect of Sengstaken-Blakemore tube in assisting cyanoacrylate injection combined with sclerotherapy and variceal ligation under emergency endoscopy in treating escophageal and gastric variceal bleeding. Methods 60 patients were randomly selected, and were evenly divided into 2 groups single blindly. Endoscopic cyanoacrylate injection, sclerotherapy and variceal ligation were performed in control group, and additional Sengstaken-Blakemore tube were used in experimental group. Results All the 30 patients in study group got effective hemostasis (30 of 30, 100.00 %), whereas only 23 patients in control groups stopped bleeding (23 of 30, 76.67 %) (P < 0.05). escophageal and gastric variceal were cured 19 patients in the experimental group (19 of 30, 63.33 %) , and only 4 were cured in the control group (4 of 28, 14.28 %) (P < 0.05). Meanwhile, occurence of fever, chest pain, hospital days and hospitalization costs of experimental group was significantly lower than that in control group (P < 0.05). Conclusions Treating the escophageal and gastric variceal bleeding, using endoscopic cyanoacrylate injection, sclerotherapy; and variceal ligation under emergency endoscopy combined with Sengstaken-Blakemore tube could significantly increase the therapeutic efficiency as well as reduce complications and therapy cost.

Objective: To analyze influencing factors of in-stent restenosis after coronary artery stent implantation, to provide theoretical support for clinical prevention of restenosis. Methods: Clinical data of 123 patients, who received coronary artery stent implantation in our hospital from Mar 2011 to Sep 2013 and received coronary angiography follow-up one year after operation, were retrospectively analyzed. In-stent restenosis was regarded as stenosis of inner diameter of implanted stent≥50%, so patients were divided into restenosis group (n=35) and non-restenosis group (n=88). Multi-factor Logistic regression analysis was used to analyze influencing factors of coronary in-stent restenosis. Results: Compared with non-restenosis group, there were significant reductions in serum level of total bilirubin [(14.02±6.76) μmol/L vs. (10.90±4.51) μmol/L] and stent diameter [(3.06±0.86) mm vs. (2.87±0.44) mm] in restenosis group, P<0.01 both. Multi-factor Logistic regression analysis indicated that blood glucose level was independent risk factor for restenosis after coronary artery stent implantation (OR=2.545, P=0.035), while stent diameter and serum level of total bilirubin were its protective factors (OR=0.857, 0.850, P<0.05 both). Conclusion: Blood glucose level is an independent risk factor for restenosis after coronary artery stent implantation, while stent diameter and serum level of total bilirubin are its protective factors.

BACKGROUND:There is a lack of safe and effective modular lentivectors in differentiation regulation of embryonic stem cel s. OBJECTIVE:To construct a modular lentivector, Puro-Nanog-hrGFP, with Nanog promoter-control ed humanized renil a reniformis green fluorescent protein (hrGFP) and puromycin and to observe the expression of Nanog during the differentiation of Nanog-hrGFP-transfected mouse embryonic stem cel lines. METHODS:After PCR amplification, Nanog, hrGFP and entry vector were recombined into the pDest-puro vectors to generate the lentiviral expression vector, Puro-Nanog-hrGFP, by the LR reaction. Through lentivirus production, transduction and puromycin screening, the transduced cel lines with Nanog-hrGFP gene were generated and identified. Expression of Nanog during the differentiation of transgenic mouse cel lines was detected. RESULTS AND CONCLUSION:The lentiviral expression vectors Puro-Nanog-hrGFP were constructed successful y by Gateway technology, and then the transducted cel lines were obtained by lentiviral infection. The expression of Nanog was gradual y decreased during the process of transgenic cel lines differentiation, which provides a new tool for further investigation on regulation of stem cel differentiation.

OBJECTIVETo observe the effect differences on post-stroke dysphagia among acupoint injection combined with neural electrical stimulation, acupoint injection, neural electrical stimulation, and swallowing training respectively, so eligible intervention can be applied to this kind of disease.
METHODSOne hundred and eight-three patients of post-stroke dysphagia were randomized into a comprehensive treatment group (42 cases), an acupoint injection group (44 cases), a neural electrical stimulation group (49 cases) and a swallow training group (48 cases) and were treated with the comprehensive therapy of acupoint injection and neural electrical stimulation, acupoint injection, neural electrical stimulation and swallowing training separately. The treatments for 10 days made one session. There were 3 days at the interval among treatment sessions and 3 sessions were required totally. The cases in those treatment groups were blankly controlled with the other 47 patients of post-stroke dysphagia. All the patients received basic rehabilitation treatment. The modified water swallowing test was conducted to assess the efficacy before treatment, 10 days after treatment and 30 days after treatment in each group separately. The clinical efficacy, score of water swallowing test and improvement in water swallow test were compared among the groups.
RESULTSAfter 10-day treatment, the differences in efficacy and score of water swallow test were not significant in each group (all P > 0.05). After 30-day treatment, the effective rate (94.29%, 33/35) in the comprehensive treatment group was apparently better than 68.75% (22/32) in the acupoint injection group, 80.00% (32/40) in the neural electrical stimulation group, 67.50% (27/40) in the swallowing training group and 42.86% (12/28) in the blank group separately. The score in water swallow test in the comprehensive treatment group was lower than that in each of the other groups (1.37 ± 0.60 vs 2.03 ± 1.00, 1.90 ± 0.90, 2.20 ± 0.72, 2.71 ± 0.90, all P < 0.05). The differences in the effective rate and score in water swallow test were not significant among the acupoint injection group, neural electrical stimulation group and swallowing training group (all P > 0.05), which indicated that the improvement in swallowing function in the comprehensive treatment group was significantly superior to the other groups (all P < 0.05).
CONCLUSIONThe comprehensive therapy of acupoint injection and neural electrical stimulation achieves the much better efficacy on post-stroke dysphagia.

Journal of Integrative Medicine 2008;6(2):115-8
Qualitative research methods are becoming more and more important in medical research area. Some qualitative researches played important roles in the exploration and the spread of core ideas of Chinese medicine. The report of qualitative research should be transparent and credible according to the standardized report criterion. On the basis of 22 criteria, the Consolidated Criteria for Reporting Qualitative Research (COREQ) was developed and published in September 2007. This introduction to COREQ will be helpful to Chinese qualitative researchers and readers in the implementation of high quality of medical qualitative research in China.
