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.

To study the misdiagnostic reasons of valua Bowenoid papulosis. MethodTwenty-two cases of Bowenoid papulosis were retrospectively analysed. ResultsSeven cases were diagnosed as vulua Bowen's disease, 10 cases cindyloma acuminatum, 2 cases malignant melanoma and 3 cases melanocytic nevus. ConclusionsThe presence of mild to severe cytological atypia is a feature of Bowenoid papulosis. The diagnosis should be made according to both clinical and pathologic features. The disease may be spontaneously regressed.

This study aimed to amplify major genome segments (VP7, VP4, VP6, VP2 and NSP2-5) of porcine G3 group A rotavirus (GARV) LLZ212 isolated in our laboratory, determine their genotypes, and explore the evolutionary relationships between G3 GARV strains isolated from humans and pigs in Lulong County, Hebei Province, China. Major genome segments of seven GARV strains were amplified by reverse transcription-polymerase chain reaction (RT-PCR) and the segments were sequenced. The genome segments of seven GARV strains were determined by the online RotaC genotyping tool (RotaC v2.0). The reference sequences of each GARV genome segment were downloaded from GenBank. Homology and phylogenetic evolutionary analyses were conducted using the MEGA 5.0 and DNAStar software packages. LLZ212 isolated from pigs in Lulong had the following genotype: G3-P[8]-I5-C1-N1-T1-E1-H1. All human GARV strains had the following genotype: G3-P[8]-I1-C1-N1-T1-E1-H1. The VP7, VP4, NSP4 and NSP5 genes of the LLZ212 strain had the highest nucleotide identities with the human GARV E885, CMH014/07, Wa and RMC321 strains, respectively, and these clustered together in a sublineage. The VP6, NSP4 and NSP5 genes of the LLZ212 strain shared the highest nucleotide identities with the porcine GARV PRG921 strain, while VP2 associated most closely with porcine GARV OSU strain, and these also clustered in a sublineage. A rare porcine G3-P[8]-I5-C1-N1-T1-E1-H1 GARV strain was identified, which may represent a reassortment between porcine and human viruses. In conclusion, the VP7, VP4, NSP4 and NSP5 genes of LLZ212 share high levels of sequence identity with human GARV, while VP2, VP6, NSP2 and NSP3 cluster with porcine GARV.

Objective To describe the status of breast reconstruction patients′decision regret, self-efficacy and satisfaction with information in the preoperative period, and discuss the correlation among them. Methods Four instruments were used to investigate 100 breast reconstruction patients in one tertiary hospital in Guangzhou, including participants′ personal profile, Decision Regret Scale, Modified Stanford Self-Efficacy Scale and the subscale of Information Satisfaction of Breast Reconstruction-Questionnaire. Results The mean score of Decision Regret Scale was (10.8 ± 2.5)points in breast reconstruction patients, and the minority of patients experienced decision regret (30%, 30/100). The mean score of self-efficacy and satisfaction with information in the preoperative period were (6.6±1.9) and (2.9± 0.6) points. The study also found that decision regret was negatively correlated with self-efficacy and satisfaction with information in the preoperative period (P < 0.01). Conclusions Totally 30 percent of patients experienced decision regret to undergo breast reconstruction. However, patients who had lower levels of self-efficacy and satisfaction with information in the preoperative period were at greater risk to experience decision regret to undergo breast reconstruction. The results may assist health care professionals to provide appropriate psychological support, care and information.
