Objective:To determine the curative effect of Ginkgo Biloba extract on the back chapped skin in SD rats. Methods:Totally 60 SD rats were randomly divided into 6 groups with 10 rats in each. One group was the blank control group, while the other five groups with the same back chapped skin were respectively treated with different therapy regimen, namely one group was the model group without any treatment, one group was urea group treated with the commercially available urea, and the last three groups were re-spectively treated with Ginkgo Biloba extract at the dose of 5%, 1% and 0. 2%. The pathological tissue was observed after HE stai-ning, and the content of hydroxyproline ( Hyp) in skin was determined by alkaline hydrolysis. Results:The skin lesion and the score of pathological section were studied and the content of Hyp in the damaged skin was determined. The comprehensive score for the groups was 0, 13. 2, 7. 4, 11. 0, 5. 8 and 6. 6, respectively, and the content of Hyp was (4. 57 ± 0. 07), (2. 41 ± 0. 27), (3. 29 ± 0.57), (2.55 ±0.31), (3.24 ±0.26) and (3.37 ±0.24) μg·mg-1,respectively. There was significant difference in the curative effect between the Ginkgo Biloba extract groups at high dose (5%) and medium dose (1%) and the model group (P<0. 05), which showed no obvious difference when compared with the urea group (P>0. 05). Conclusion:The extract of Ginkgo Biloba has a certain effect on the back chapped skin in SD rats, which may contribute to the external preparations of Ginkgo Biloba extract.

In the middle of 1990 s, it was discovered that sirolimus had inhibitory effect on the proliferation of T lymphocytes , therefore, it is used for the treatment of anti-tumor cells.At present, the dosage forms of sirolimus are capsules , oral liquid and tab-lets.However, because of good fat-soluble and poor water-soluble property, its bioavailability is low with many side reactions .In order to provide reference for the further studies of sirolimus , the literatures in recent years were searched in Pubmed , Springer, CJFD,VIP Chinese periodical database and Wanfang data , and the research progress in the new dosage forms of sirolimus was summarized .

Results: hTe renal allogratf was removed in 5 of the 6 patients due to repeated external iliac arteryhemorrhage: 2 patients were replaced the external iliac artery with reversed autogenous great saphenous vein, 2 patients underwent the bilateral femoral artery bypass surgery, and 1 was repaired the external iliac artery directly. The other 1 was resected the renal allograft and the involved external iliac arteries due to fungal mass in the external iliac artery. Among the 6 patients, except 1 patient died atfer the surgery of the repair of the external iliac artery, the other 5 are all alive. Conclusion: Vascular replacement and artery bypass are effective methods for patients with external iliac artery vascular complications atfer kidney transplantation.

Objective:To identify the polymorphisms of cytochrome P450 3A5 gene (CYP3A5) and multidrug resistance gene 1 (MDR-1) and their distributions in Hans renal transplant recipients in Hunan province, we analyzed the difference of the gene polymorphisms and distributions between Hunan province and 11 other provinces of China.
Methods:We collected 598 Hans renal transplant recipients who had operation or follow-up examination in 3rd Xiangya Hospital from Hunan province. We examined the gene polymorphisms of CYP3A5 and MDR-1 and compared their distributions with the data from 11 other provinces of China by chi-square test.
Results:hTere were CYP3A5*1/*1 genotype in 58 cases (9.7%), CYP3A5*1/*3 genotype in 251 cases (42.0%), CYP3A5*3/*3 genotype in 289 cases (48.3%);MDR-1 3435CC genotype in 238 cases (39.8%), MDR-1 3435CT genotype in 263 cases (44.0%), MDR-1 3435TT genotype in 97 cases (16.2%). Frequency of CYP3A5*1/*1 and*1/*3 genotypes of Hunan province was higher than the that from the 11 other provinces of China and the frequency of mutator*3 was lower. Frequency of MDR-1 3435CC and 3435CT genotypes of Hunan province was higher and the frequency of mutator T was lower than that from the 11 other provinces of China.
Conclusions:There were significant difference in gene polymorphisms and distributions of CYP3A5 and MDR-1 between Hunan province and the 11 other provinces of China. It may be a guideline for us to use calcineurin inhibitor drugs in the early stage atfer renal transplantation.

OBJECTIVE: To evaluate the risk factors of delayed graft function (DGF) and its impact on renal transplantation from donation after cardiac death (DCD). METHODS: We conducted a retrospective study consisting of 48 subjects who underwent a DCD kidney transplantation from February 2010 to March 2012. We classified the recipients into two groups: an IGF (immediate graft function) group (n=30) and a DGF group (n=18), and analyzed the risk factors of DGF and its impact on transplantation. RESULTS: DGF occurred in 18 of the 48 (37.5%) kidneys from DCD donors, and the occurrence of DGF did not adversely influence the survival of patients (P=0.098) and graft (P=0.447). In the univariate analysis, the preoperative dialysis time of recipients (P<0.001), HLA mismatch site (P<0.001), the cause of brain death (P=0.011), BMI (P<0.001), preoperative serum creatinine of donors (P=0.0001), norepinephrine used in donors (P<0.001), warm ischema time (WIT) (P<0.001), cold ischema time (CIT) (P<0.001) showed significant differences. In the multivariate analysis, cerebral hemorrhage as the cause of brain death (P=0.022, OR=39.652), preoperative serum creatinine of donors≥177 μmol/L (P=0.008, OR=57.148) and the preoperative dialysis time of recipients≥12 months (P=0.060, OR=15.060) were independent risk factors for DGF development. CONCLUSION The independent risk factors for DGF are the cause of brain death, the terminal creatinine level, and the preoperative dialysis time.

OBJECTIVETo evaluate the application of inferior vena cava filter (IVCF) in prevention of peri-operative pulmonary embolism (PE) in lower limb bone fracture patients with deep venous thrombosis (DVT).

METHODSFrom January 2003 to December 2012, 2 248 cases of lower limb and pelvic fractures with DVT were retrospectively analyzed. Before the procedure of IVCF implantation began, January 2003 to December 2007, there were 1 052 cases of acute trauma patients with DVT were classified as the group of early none-IVCF. The IVCF implantation was began since January 2008. From that time to December 2012, 712 cases of bone fractures with DVT received filter implantation, which were classified as IVCF group. The other 484 patients who had not undergone filter deployment were divided as group of late none-IVCF. The baseline conditions of the three groups were significantly different in addition to the ages between group of early none-IVCF and IVCF group. The incidences of PE and mortality of PE in each group were recorded and analyzed by χ(2) test.

RESULTSThere were totally 31 cases of symptomatic PE, among which 12 cases died. Totally 712 filters were deployed successfully without any major complications. The incidences of symptomatic PE were 0.14% (1/712), 2.19% (23/1 052) and 1.45% (7/484) in IVCF group, group of early none-IVCF and group of late none-IVCF, respectively. The mortality of PE were 0 (0/712), 0.86% (9/1 052) and 0.62% (3/484) in these groups. The incidence of symptomatic PE in IVCF group was significantly different from that in the group of early and late none-IVCF (χ(2) = 11.762, P = 0.001; χ(2) = 7.395, P = 0.007, respectively). The mortality of IVCF group was also significantly lower compared with the other two groups (χ(2) = 6.122, P = 0.013; χ(2) = 4.424, P = 0.035, respectively).

CONCLUSIONIVCF implantation effectively prevents symptomatic and fatal PE of patients of lower limb and pelvic fractures with DVT in the peri-operative period.

OBJECTIVE: To evaluate the recovery of patients with end-stage renal disease (ESRD) receiving kidney transplant from cardiac death donors, and to assess graft survival in China from this type of donor. METHODS: A total of 48 cases of patients with ESRD have received the kidneys from cardiac death donors in our hospital between February 2010 and March 2012. We retrospectively analyzed data on the preoperative and postoperative serum creatinine concentrations, on the survival of recipients and allografts with a view to investigating prognoses after this type of kidney transplant. RESULTS: Primary non-function (PNF) did not occur in any of the 48 recipients. Delayed graft function (DGF) occurred in 18 of 48 (37.5%) of kidneys from cardiac death donors, but the occurrence of DGF did not adversely influence patient's survival (P=0.098) or graft survival (P=0.447). Seven of 48 (14.6%) recipients lost their graft. Over a median follow-up period of 8 months (range 0.5-23 months), 39 of 41(95.1%) recipients' graft function had fully recovered. The actuarial graft and patient's survival rates at 1, 3, 6 and 12 months after transplantation were 95.7%, 93.0%, 90.0%, 87.5%, and 100%, 94.9%, 90%, 87.5%, respectively. CONCLUSION As the legislation of donation after brain death (DBD) has not been ratified in China, the use of kidneys from cardiac death donors might be an effective way to increase the number of kidneys available for transplantation here. Our experience indicates good short- and mid-term outcomes with transplants from cardiac death donors.

OBJECTIVE: To evaluate the prevalence and risk factors for the formation of aberrant artery collaterals in the uterus during uterine artery embolization (UAE).
 METHODS: The data of 144 women with scar in the uterus due to cesarean were retrospectively analyzed. They underwent UAE in the period of 2009-2014 and were divided into two groups according to a standard with or without the aberrant artery collaterals in the uterus. The risk factors were analyzed.
 RESULTS: Aberrant artery collaterals were found in thirty-four patients. According to multiple logistic regression analysis, the presence of placenta previa (RR=78.556, 95% CI: 2.869-2 150.651, P=0.010), pelvic inflammatory disease (RR=6.633, 95% CI: 1.595-27.592, P=0.009), pregnancy complications (RR=7.264, 95% CI: 1.622-32.531, P=0.010), abortions (RR=18.381, 95% CI: 1.683-200.752, P=0.017) and uterine fibroids or adenomyosis (RR=12.580, 95% CI: 1.004-157.550, P=0.050) were the factors for the presence of aberrant artery collaterals.
 CONCLUSION Aberrant artery collaterals were more frequent in patients with pelvic inflammatory disease, pregnancy complications, abortions and uterine fibroids or adenomyosis.

BACKGROUNDOur goal was to evaluate the outcomes of kidney transplants from controlled cardiac death donors compared with brain death donors by conducting a meta-analysis of cohort studies.

METHODSThe PubMed database and EMBASE were searched from January 1980 to July 2013 to identify studies that met pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. Two authors independently extracted information on the designs of the studies, the characteristics of the study participants, and outcome assessments.

RESULTSNine cohort studies involving 84 398 participants were included in this meta-analysis; 3 014 received kidneys from controlled cardiac death donors and 80 684 from brain death donors. Warm ischemia time was significantly longer for the controlled cardiac death donor group. The incidence of delayed graft function was 2.74 times (P < 0.001) greater in the controlled cardiac death donor group. The results are in favor of the brain death donor group on short-term patient and graft survival while this difference became nonsignificant at mid-term and long term. Sensitivity analysis yielded similar results. No evidence of publication bias was observed.

CONCLUSIONThis meta-analysis of retrospective cohort studies suggests that the outcome after controlled cardiac death donors is comparable with that obtained using kidneys from brain death donors.
