OBJECTIVETo study a new method of venous flap that is improved on its persistence and quality.

METHODSNew Zealand white rabbits were subdivided randomly into 4 groups. All rabbits were operated by harvesting a flap from the latero-abdominal wall and then sutured it in the original position. Group A: the superficial epigastric vein in the pedicle was left open (only one inflow vein remained). Group B: the pedicle vein of the proximal and distant end were left open (keeping an inflow vein and a principal out). Group C: the pedicle vein and a tributary vein were left open (keeping an inflow vein and a tributary outflow vein). Group D: the pedicle vein and two tributary veins were left open (keeping an inflow vein and two tributary outflow veins). Survival rate, MDA of the tissue, histology and ultra-microstructure were examined.

RESULTSSurvival rate of A, B, C, D were improved in order. Statistic difference is significant (P < 0.05) between group and group other than C and D. The content of MDA was heightened with statistically significant differences (A > B > C > D) among the four groups 8 hours postoperatively, but fell back to the normal level in group D and C and kept a high level in group A and B at 72 hour postoperatively. Histology and ultra-microstructure exam showed that degeneration of collagen fiber and karyopyknosis of cell is more obvious in Group A and Group B than Group C and Group D.

CONCLUSIONSThe higher survival rate of venous flap is possible by designing the more reasonable venous flap outputs pedicles which can alleviate the high tension dropsy and maintain the valid equilibrium of pour with flow in the venous flap.

Objective::To detect the expression levels of peripheral blood Treg/Th17 cells and related cytokines in patients with Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) with different traditional Chinese medicine (TCM) syndrome " Yanghuang-Yinyanghuang-Yinhuang" , in order to explore the cellular immunological characteristics of different TCM syndromes of liver failure. Method::The 32 cases of patients with HBV-ACLF in early, middle and late stages in line with the " Yanghuang-Yinyanghuang-Yinhuang" TCM syndrome grouping were selected. Flow cytometry was used to detect the frequency expression of Treg/Th17 cells in peripheral blood. The expression levels of interleukin-10(IL-10), transforming growth factor-β(TGF-β), interleukin-17A(IL-17A), tumor necrosis factor-α(TNF-α) and interleukin-23(IL-23) were detected by cytometric bead array (CBA). The expressions of transcription factor forkhead box P3(FoxP3) and retinoid-related orphan nuclear receptor-γt(ROR-γt) mRNA were detected by Real-time PCR. The SPSS 20.0 software was applied in data statistics and processing to analyze the expression characteristics of Treg/Th17 cells and related cytokines in patients with different TCM syndrome types of HBV-ACLF. Result::The patients with HBV-ACLF Yanghuang syndrome were mainly distributed in the early stage of liver failure, those with Yinyanghuang syndrome were mainly distributed in the middle stage, and those with Yinhuang syndrome were distributed in the late stage. From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, the frequency of Treg and Th17 cells gradually increased, and the differences among the groups were statistically significant (P<0.05). From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, Treg cytokines IL-10, TGF-β gradually increased, and the differences among the groups were statistically significant (P<0.05). Th17 cytokines IL-17A, TNF-α, IL-23 gradually increased, of which IL-17A were differences between Yanghuang syndrome and the Yinyanghuang syndrome, as well as Yanghuang syndrome and Yinhuang syndrome (P<0.05). From Yanghuang syndrome, Yinyanghuang syndrome to Yinhuang syndrome, the expression of FoxP3 was gradually decreased, while that of ROR-γt was gradually increased, and the differences among the groups were statistically significant (P<0.01). Conclusion::There is a certain correlation between the different course of early, middle and late stages of HBV-ACLF and the distribution of TCM syndromes. The frequency of Treg and Th17 cells and the correlation of IL-17A, TGF-β and IL-10 with TCM syndrome differentiation are related, suggesting that Treg and Th17 cells have a certain reference value for the diagnosis of patients with HBV-ACLF and the syndrome differentiation of TCM syndromes.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.
METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.
RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).
CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.
