Objective To investigate the association of insulin dose with clinical factors of type 2 diabetes. Methods We reviewed the data of 214 type 2 diabetic patients who received insulin regimens.We compared the insulin dose and period at the targeted blood glucose levels among 6 groups according to different type of oral hypoglycemic agents. Results There existed statistically significant correlations of the glucose-targeted insulin dose with course,FPG,BMI,combination therapy with oral hypoglycemic agent(P<0.1,test level P=0.1).Merely metformin failure group took less insulin than the group admitted due to combination therapy failure (P=0.016, 0.53(0.35～0.62)U/kg and 0.63(0.51～0.75)U/kg respectively).The longest targeted period existed in the later. Relationship between the targeted bedtime insulin NPH dose and FPG level can be demonstrated by equation Y=0.255X+7.8. Conclusions The targeted insulin dose is influenced by synthetic factors. Patients admitted due to combination oral hypoglycemic drug failure have the maximal targeted insulin dose and the longest titration period. The final bedtime insulinNPH dose can be predicted by FPG level.

Objective To evaluate the clinical effects of platelet-rich plasma in treatment of DeepⅡburn wounds. Methods Sixty eight cases of inpatients with Deep Ⅱburns were selected, whose age were from 1 to 65 years and their burn areas were between 5%~62%of total body surface area (TBSA). Deep gradeⅡburn of each sample was divided into two parts. Part A was the treatment group and part B was the control group.The burn wounds in the treatment group were treated with platelet-rich plasma and the counterpart in the control group were treated with SD-Ag. Healing time ,recovering rate and the frequency of dressing changes,frequency of changing the most innerlayer gauze and the rate of wound infection were also analyzed. Finally the laboratory abnormalities and adverse effect were monitored regularly. Results The healing time of the treatment group (16.5±3.1 ) d was shorter than that of the control group (19.5±3.8 ) d. The recovering rate of the treatment group was higher than that of the control group on the 14th and 17th day after treatment. There were statistically sig?nificant differences between these two groups (P<0.05). After two weeks’treatment, the internal and external dressing per?meability into wet gauze layers were 20.6 ± 1.7, which were significantly decreased than that in the control group 23.3 ± 5.9. The frequency of dressing changes was(7.2±1.1)times in treatment group versus(9.2±1.4)times in control group and the frequency of changing the inner most layer gauze was( 2.3±0.6)times in the treatment group versus(5.3±1.3)times in con?trol group. There were 5 inflammation reaction cases in the treatment group, but 13 cases in the control group. However, there was no statistic significance between the two group in the outcomes of bacterial culture, the laboratory abnormalities and the adverse effect. Conclusion Platelet-rich plasma can remarkably shorten the healing time,improve healing rate,re?duce frequency of dressing change and promote wound healing for deepⅡburn wound. PRP is a potential safety reagent in treating deepⅡburn wound.

OBJECTIVE: To review classification and synthesis of amphiphilic polymers containing polyethylene glycol and the application as drug carriers.DATA SOURCE: A computer-based research was conducted in SCI-Expanded, El Compendex and China Journal Full-text Database for articles concerning classification and synthesis of amphiphilic polymers containing polyethylene glycol and their micelles application as drug carriers published from January 2000 to July 2009.DATA SELECTION: A total of 616 articles were primarily obtained. Following reading titles and abstract, articles addressing detail classification and synthesis of amphiphilic polymers containing polyethylene glycol and representative micellar influencing factor were included. Totally 31 English and Chinese literatures were collected for further analysis.MAIN OUTCOME MEASURES: Classification, synthesis and drug vector mechanism of amphiphilic polymers containing polyethylene glycol and the micellar application as drug carriers were measured.RESULTS: Star-shaped copolymer could elevate micellar stability, but there were many arm numbers, whicti might induced a decrease in drug carrier volume. Special group introduced in copolymer contributed to the combination of drug and carrier. To connect target group could provide target transport property. The length and density of polyethylene glycol chain in copolymer was related to micellar function. Changed the length and density of polyethylene glycol could obtain polymer micelles that circulated in vivo for a long time.CONCLUSION: Amphiphilic polymers containing polyethylene glycol has outstanding potential in medical drug carrier field and isolation technique.

Background:Helicobacter pylori( Hp)is listed as Group 1 human carcinogen. Transcription factor FOX family plays important role in the development of tumor,and FOXA1 is a key target transcription factor of some microRNAs( miRNAs). Aims:To investigate the relationship of Hp infection with expression of FOXA1 in gastric mucosal tissues. Methods:Eighty patients undergone gastroscopy from Jan. 2014 Sept. 2014 were enrolled. Hp infection was detected by 14 C-urease breath test( 14 C-UBT),modified Giemsa staining and bacterial culture. Expression of FOXA1 in gastric mucosal tissues was determined by immunohistochemical SP method. Results:FOXA1 expression in Hp positive tissues was significantly higher than that in Hp negative tissues(73. 8% vs. 47. 4%;χ2 =4. 81,P<0. 05). Conclusions:High expression of FOXA1 in gastric mucosal tissues suggests that miRNAs pathway may be one of the molecular mechanisms of Hp infection leading to gastric intraepithelial neoplasia even gastric cancer.
