Objective To investigate the association between HbA1c status,arterial stiffness and endothelial function in subjects with type 2 diabetes mellitus(DM).Methods The study group consisted of 338 DM patients,including 74 subjects with normal HbA1c(≤ 6.0％)(Group A),102 subjects with mildly increased HbA1c(HbA1C increased by less than 6.5％)(Group B)and 162 patients with high HbA1c level (HbA1c increased by more than 6.5％)(Group C).All patients were evaluated for glucose,HbA1c,TC and TG.Pulse wave velocity(PWV)and flow-mediated dialation(FMD)were performed simultaneously.Results Compared with Group A,Group B and C had higher baPWV([1734 ± 343]cm/s vs.[1537 ± 313]cm/s and [1853 ± 364]cm/s vs.[1537 ± 313]cm/s).Patients in Group C had a higher baPWV than those in Group B ([1853 ± 364]cm/s vs.[1734 ± 343]cm/s,P =0.006).The patients in group A had a lower level of FMD than that of group B and C([4.20±3.13]％ vs[5.29±3.92]％,[4.09±2.79]％ vs.[5.29±3.92]％,P＜0.01).Leaner association analysis showed a positive correlation between baPWV and HbAlc(r =0.53,P ＜0.01).baPWV was negatively correlated with FMD(r =-0.25,P ＜0.01).Logistic regression analysis showed that HbA1c(OR32.19％,CI 11.26 ～53.12,P＜0.001),age(OR 14.21,95％ CI 11.43 ～ 17.00,P＜0.001),systolic blood pressure(OR 7.36,95％ CI 6.12-8.59)and TC(OR:0.31,95％ CI:9.97-70.64)were independent predictors for the increased arterial stiffness(baPWV).Conclusion Arterial stiffness parameters varied significantly across subgroups of patients with different levels of HbA1c and the arterial stiffness was positively associated with deranged glucose homeostasis.

This study was aimed to compare the function of dendritic cells (DCs) in patients of Y in-Huang syn-drome and Y ang-Huang syndrome from the peripheral blood of HBV related hepatic failure. Jaundice patients of HBV related hepatic failure were divided into two groups, which were the Y ang-Huang syndrome group and Y in-Huang syndrome group. And a healthy control group was also established. The DCs were separated and cultured in vitro from PBMCs in the peripheral blood. Surface molecules such as HLA-DR, CD80, CD86, CD83 and CD1αwere detected by the flow cytometry. And the level of IFN- α and IL-4 in the supernatant of DCs were also de-tected. The expression difference of inflammatory cytokines and immune cells between Y in-Huang and Y ang-Huang syndrome in patients of HBV related hepatic failure were compared. The results showed that compared with healthy people, the expression rate of DCs phenotype such as HLA-DR, CD1α, CD83, CD80, CD86 in patients of HBV related hepatic failure was significantly decreased (P < 0.01); the excreted factor IFN-α had a significant rising (P < 0.01). Compared to Y ang-Huang syndrome group, the expression rate of CD83 and CD86 in the Y in-Huang syndrome group of HBV related hepatic failure patients was significantly reduced (P < 0.01). And the ex-creted factor of IL-4 had a significant rising in Y in-Huang syndrome group (P < 0.01). Compared to the Y in-Huang syndrome group, the excreted factor IFN-α in the Yang-Huang syndrome group had a significant rising (P< 0.01). It was concluded that DCs function of patients with HBV related hepatic failure in both Y in-Huang syn-drome and Y ang-Huang syndrome group showed low immune function. And the immune function of the Y in-Huang syndrome group was lower. There was excessive releasing of inflammatory factors in the Y ang-Huang syn-drome group. And there was enhanced anti-inflammatory cytokine expression in the Y in-Huang group.

Remote organ ischemic preconditioning is to conduct a transient and sublethal ischemic adaptation in non-vital organs before occurring cerebral ischemia/reperfusion injury in remote vital organs. Remote organ iscbemic preconditioning has been studied for as long as 15 years in the field of myocardial iscbemia. However, only recently it has become a therapeutic strategy for the treatment of cerebrovascular diseases, This article briefly reviews the methods and mechanisms involved in the protective effects of cerebral ischemia of remote organ ischemic preconditioning.

Aim To prepare the monoclonal antibodies (mAbs) against human CD28 and to study its biological feature. Methods The hybridoma cell lines were obtained by fusing spleen cells of Blab/c mice that had been immunized with murine lymphoma cells transfected with full-length huaman CD28 cDNA to myeloma cells Sp2/0. Ascites were induced to produce the mAbs. The specificity and affinity of the mAb 18G8 was verified by CD28 competitive inhibitory test and FACS. Reactivities of mAb 18G8 to PBTC, U266, 8226, Jurkat and Daudi cell were studied by indirect immunofluorescence staining. mAb 18G8-inducing proliferation of peripheral blood T cells (PBTCs) was determined by [3H]thymidine incorporation test. Results Five hybridoma cell lines were obtained. mAb 18G8 secreted by one of the them, belong to mouse IgG2a. It recognized a epitope different from which recognized by the standard mAb(clone CD28.2). The Reactivitrates of the mAb 18G8 to PBTC, U266, 8266, Jurkat and Daudi cells were 70.2％ , 99.3％ , 98.6％ , 76.4％ and 1.9％ , respectively, similar with CD28.2. It was indicated that different antigen epitopes expressed on all above cells. mAb 18G8 could promote the PBTC proliferation in vitro(SI=7). It was indicated that The substitution of mAb 18G8 for B7-1 molecule could also mediate the costimulatory signals. Conclusion 18G8 is a specific and functional anti-CD28 mAb it may be of significant value in basic studies and clinical application.

Objective To investigate the effect of tissue expansion in facial congenital giant nevus.Methods From October 2014 to October 2016,7 cases of facial congenital giant nevus patients were treated with expanded skin flaps,including single expansion and secondary expansion.Partial excision and skin tissue expansion were used to drastically remove giant pigmented nevi on body or extremities of infants.There were some points for attention during the surgery:the size and location of the partial excision and expander should be designed reasonably;no tumor-manipulation and non-tension principle should be taken great notice,and expanders should be linked up with one another when several expanders were used at the same time,so as to reduce the possibility of forming the envelop,which was favorable for the second surgery of transfer of a skin flap.Results All cases of giant pigmented nevi excision were on the face,which were completely removed from the patients.The areas of the nevi were from 7 cm × 5 cm to 15 cm × 13 cm.All patients were followed up for 3-12 months (mean 6 months).All flaps survived well.Expander exposure was happened in 2 cases with no bad results.One case of scar received late repair due to surgical scars and all got satisfactory results.Conclusions Tissue expansion is an ideal method in the treatment of facial congenital giant nevus.

Objective:To investigate the clinical effect of enteral nutrition (EN) on patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).Methods:96 cases of acute exacerbation of COPD patients admitted to our hospital from January 2015 to December 2016 were randomly divided into observation group (48 cases) and control group (normal diet,48 cases).The patients in two groups were given anti-infection and other symptomatic treatments equally.The serum protein levels and pulmonary function in the two groups were compared after 2 weeks.Furthermore,antibiotic use durations,hospitalization days and the re-admission rates within 3 months were observed and compared between two groups.Results:The serum albumin and pre-albumin levels,FEV1 and FEV1/FVC in the observation group were significantly elevated in comparison with those in the control group.And the antibiotic use durations,hospitalization days and the re-admission rates within 3 months remarkably decreased in the observation group (P ＜ 0.05).Conclusion:Enteral nutrition could improve the nutritional status and pulmonary function in patients with acute exacerbation of COPD,shortening the length of hospital stay and the durations of antibiotic use and reducing the rates of re-admission.Enteral nutrition may be worth applying widely in clinical COPD patients in future.

Objective To measure the leakage rate in the process of expansion in vivo and in normal saline and the over-expansion property of the expander.Methods We chose 17 cases that were treated with the skin expansion.We recorded total injected saline volume intentionally in these cases before the second surgery,and recorded the remainder of the volume of saline postoperatively.We injected normal saline into 8 expanders,respectively,exceeding 50％ of the volume-rating;and subsequently put these expanders into plastic bucket filled with saline.30 days after,we measured the remaining volume of the normal saline.We injected 100 ml normal saline into 4 expanders,respectively,of which nominal volume was 100 ml,and then left these expanders in saline and measured the remainder volume of the saline 30 days later.In the second time,we injected 150 ml and repeated the abovementioned process.It was repeated 7 times until the injection volume reached 400 ml.We processed the data and depicted a curve of effective expansion.Results The results showed that the leakage rate reached (29.0+12.5) ％ in vivo.Experiments in vitro confirmed that 85.0％ (8.0/9.4) of the saline leaked through the injection port and 14.8％ (1.4/9.4) leaked through the membrane of the expander.In addition,over-expansion performance index test confirmed that the over-expansion property of an expander was about twice the nominal volume.Conclusions The expander is not completely sealed structure.Normal saline can leak through the injection part and the membrane of the expander.The over-expansion property of an expander is limited.When the volume injected into the expander exceeds a certain value,the effective expansion performance is not increased with it.
