Aim To investigate the effect of the extract of Averrhoacarambola L.root (EACR)on renal func-tion in diabetic mice and its anti-oxidative action. Methods Diabetic mice were established by tail vein injection with 120 mg·kg-1 streptozotocin (STZ)and were divided into 5 groups:model control group,val-sartan control group,and low-,middle-,high-dose of EACR groups (300,600,1 200 mg·kg-1 ).And 10 normal mice consisted of normal control group.The fasting blood glucose (FBG)of mice was detected be-fore and after administration of drugs.After last admin-istration,the blood and urine samples were collected for creatinine (Cr),urea nitrogen (BUN),urine and 24 h urinary protein determination.The activities of superoxide dismutase (SOD ),glutathione peroxidase (GSH-Px)and malonaldehyde (MDA)content were determined using kits.HE staining was conducted to observe the pathological changes of kidney tissues. ELISA method was utilized to detect the contents of catalase (CAT)and reactive oxygen species (ROS ). The expressions of Cyto-C,AIF and caspase-3 proteins in kidney tissues were analyzed by Western blot.Re-sults Compared with model group,the serum bio-chemical indexes and 24 h urinary protein of valsartan and moderate-,high-dose of EACR groups were de-creased with statistical significance (P<0.05 ).After the treatment, the MDA content was decreased by EACR treatment,and SOD,GSH-Px and CAT activities were enhanced.Meanwhile the expressions of ROS, Cyto-C,AIF and caspase-3 were down-regulated.The pathological changes of kidney tissues were ameliorated by EACR through HE results.Conclusions The ex-tract of Averrhoacarambola L.root can decrease the se-rum levels of Cr and BUN,reduce the MDA and ROS contents in kidney tissue and enhance the activities of SOD,GSH-Px and CAT,down-regulate the expres-sions of Cyto-C,AIF and caspase-3 proteins in kidney tissues,elevate the anti-oxidative effect of kidney. Therefore,the renal function of diabetic mice is melio-rated.

Objective To study the effect of Tacrolimus on blood lipid after renal transplantation,and the relationship between C825T polymorphism in G protein beta 3 subunit (GNB3) gene and serum lipid levels.Method Eighty-one cases of recipients patients after renal transplantation were divided into two groups in terms of Tacrolimus concentration:normal blood concentration group (group A) and low blood concentration group (group B).The serum lipid levels at 1st,3rd,6th,and 12th month after renal transplantation were measured.Genotype was determined by the simple sequence-specific primer polymerase chain reaction (SSP-PCR).Result The percentage of patients with hypertriglyceride in group A was significantly higher than in group B during the one-year follow-up period.There was significant difference between the two groups in the serum triglyceride levels but no difference in the serum cholesterol levels.The 825C/T polymorphism in the GNB3 gene was not associated with hypertriglyceride in renal transplantations in Wenzhou.Conclusion The serum triglyceride levels in renal transplantations in Wenzhou was associated with the Tacrolimus concentration,and the incidence of hypertriglyceride is not associated with the 825C/T polymorphism in the GNB3 gene.

Objective To explore the factors related to the delayed graft function (DGF). Methods Clinical data of 150 recipients were collected and performed by Cox proportional hazards regression analysis . In addition, the glutathione S-transferase (GST) gene polymorphism of 172 donors and 157 healthy persons was analyzed by multiple PCR and SSP-PCR. Results DGF was observed in 24 patients among 150 recipients. Pretranplantation dialysis mode, PR A levels and recipient gender were uncorrelated with the incidence of DGF(P>0. 05). Urinary volume of the second 24 hours after transplantation was an independent predictor of DGF(RR=1. 002, P = 0. 001). The frequency of donor's null GSTM1 in DGF group was significantly higher than that in non-DGF group(P<0. 05). Conclusions Urinary volume of the second 24 hours after transplantation could be a predictor for DGF. The null GSTM1 in donor might be one of the factors related to the EGF.

Objective To investigate the role of BMSCg on enhancing the implant survival and bacheal epithelium regeneration. Methods After transplanted with cryopreserved 2 weeks and 6 weeks allocraft, PHK-26 labeled 3-5 passage BMSCs were injected into the recipient rats via tail vein. Rats in the control groups were injected with the same amount of PBS.We observed the histology of the transplanted trachea including epithelium growth and regeneration, and the PKH-26 fluorescence levels at the para-anastomotic trachea to evaluate the role of BMSC transplantation on the epithelium regeneration. Results Rats from BMSCs injection group survived a long period. Histological observation showed that the tracheal lumen was covered by psudo-striated ciliated columnar epithelium. The cartilage structure was intact. There are no signs of denaturation and necrosis. In the PBS injection group, epithelium regeneration is better in PBS-6-week group than PBS-2-week group. The longest survival time in PBS-6-week group was 32 days, whereas it was 10 days in PBS-2-week group. In BMSCs injection group, rats in BMSC-6-week groups survived longer than 8-week group(12 rats were terminated at 1 week, 4 weeks and 8weeks as planned). There was one rat who survived and were terminated at the designated 8 weeks time point (there were 8regenerated epithelium was similar in the two BMSC transplanted groups. PKH-26 labeled BMSCs migrated to the implant site and showed red fluorescence, with most red fluorescence shown at the anastomotic part. Conclusion BMSCs can migrate to the impaired tissue to repair it. BMSCs may exert their reparation function via enhancing epithelium regeneration.

Objective To explore clinical application value of Traditional Chinese Medicine nursing technology to decrease postoperative complication after breast cancer surgery.Methods Randomized controlled trial,large sample size,multicenter study design were adopted,and 200 patients who met inclusion criteria were randomly divided into the control group and the treatment group (100 cases in each group).The control group received routine nursing methods after breast cancer surgery.The treatment group received routine nursing methods as well as Traditional Chinese Medicine nursing intervention,such as auricular application pressure,acupoint sticking,meridian moxibustion.Data of arm circumference,Athens insomnia scale(AIS),symptom in affected arm were collected a week before and after surgery,and range of motion of shoulder joint was evaluated 3 months after surgery to compare postoperative subcutaneous effusion,skin flap necrosis,limb edema,sleep disorder and occurrence of shoulder joint dysfunction in two groups.Results The cases developed postoperative subcutaneous effusion,skin flap necrosis,limb edema were different in two groups,but the differences were not statistically significant(P＞0.05).There were significant differences between two groups in affected arm pain,swelling,skin tension,sleep,and shoulder joint dysfunction after 3 months(P＜0.05).Conclusion Traditional Chinese Medicine nursing technology can effectively decrease postoperative complication after breast cancer surgery.

Objective To investigate the effect of the polymorphisms of multidrug resistance 1 (MDR1) C3435T and G2677T on Tacrolimus (Tac) individualized treatment and prognosis of grafts in the renal transplantation recipients (RTRs).Methods One hundred and twenty-seven RTRs who treated with Tac regimen and had a stable graft function were enrolled,and were divided into adjuvant treatment group and non-adjuvant treatment group according to whether given adjuvant drugs to raise Tac trough concentrations. MDR1 C3435T and G2677T SNPs were detected by using sequence specific primers PCR.Tac trough concentrations of whole blood were measured by using enzymelabeled immunosorbent assay.Tac concentration-to-dose ratio (C/D) standardized by body weight was compared according to the various genotypes and haplotypes of MDR1 C3435T and G2677TA SNPs.Results Adjuvant treatment group including 36 recipients had a higher frequency of C genotype of C3435T than un-adjuvant treatment group (68.05％ vs 48.35％,P ＜ 0.01 ). The frequency of G2677TA polymorphisms was of no significant difference between the two group recipients (P＞ 0.05).As to non-adjuvant treatment recipients,the mean Tac DD required and C/D were not significantly different among various polymorphisms of MDR1 G2677T/A and C3435T or various haplotypes (P＞0.05).During A follow-up period of 4 years,13 recipients suffered graft dysfunction in which 84.6％ (11/13) carried 3435C genotype (P＞0.05).Conclusion The frequency of MDR1 C3435T polymorphisms in RTRs is high in the recipients given adjuvant treatment to raise Tac concentrations.Recipients with 3435C genotype were prone to graft dysfunction.

Objective To investigate the association of genetic polymorphisms in glutathione S-transferases T1 (GSTrl), M1 (GSTM1) and P1 (GSTP1) with aristolochic acid nephropathy (AAN) of Chinese people in Wenzhou of China. Methods Fifty-nine patientswith AAN (AAN group) including 29 male and 30 female as well as 157 healthy ethnically matched controls (control group) including 93 male and 64 female were enrolled in this study. The genotypes of GSTT1, GSTMI and GSTP1 were determined by multiple PCR and confronting two-pair primers PCR (CTPP-PCR). Results The genotype frequencies of GSTP1 were in Hardy-Weinberg equilibrium. Compared with the healthy controls, the frequency of GSTT1 null genotype was significantly higher in the patients with AAN (66.1% vs 48.4%,P＜0.05). Risk of A.AN for individuals with GSTT1 null genotype was 1.747 fold of those without GSTIl null genotype (95% CI=0.818-3.731). The frequency of GSTM1 null genotype, GSTP1 variant genotypes and GSTP1 G allele in the patients and in the controls were 40.7%, 28.8%, 16.1% and 47.8%, 31.8%, 17.5%, respectively, which were not significantly different. No significant differences were found in prevalence of GSTM1 and GSTP1 gene distribution between patients and controls. Conclusion GSTrl gene polymorphism appears to be associated with susceptibility to AAN in Southern China.

Paeoniflorin and its derivatives are main active compounds inGui-Zhi Fu-Ling Capsule (GZFLC). In this study, molecular imprinted polymer (MIP) was prepared by sol-gel process to obtain paeoniflorin and its derivatives in GZFLC. The static adsorption capacity of MIP was measured by scatchard equation. The results showed that the maximum apparent absorbing capacity of MIP was 52.28 mg·g-1. One-step separation of paeoniflorin from 4 g methanol samples of GZFLC was 197 mg with the purity of 89.3%. It was concluded that paeoniflorin MIP can be used to separate phaoniforin and its analogues from GZFLC.

OBJECTIVE: To explore the clinical features and genetic basis for a patient with hereditary hypophosphatemic rickets with hypercalciuria(HHRH). METHODS: Clinical data of the patient was collected. The patient was subjected to whole exome capture and next generation sequencing (NGS). Suspected variants were verified by Sanger sequencing. RESULTS: The patient presented with hypophosphatemic rickets, short stature, hypercalciuria, and renal stones. NGS showed that he has carried compound heterozygous variants of the SLC34A3 gene, namely c.532_533delCA(p.Q178Vfs*6) and c.894_925+69del(splicing). His parents were asymptomatic heterozygous carriers of one of the variants. Based on ACMG guidelines, both variants were classified as pathogenic. CONCLUSION The compound heterozygous variants c.532_533delCA (p.Q178Vfs*6) and c.894_925+69del(splicing) of the SLC34A3 gene probably underlie the disease in this child. Above finding has enriched the variant spectrum for HHRH. Based on the results, prenatal diagnosis may be provided for the family.

OBJECTIVE: To analyze the phenotype and genetic variant in a pedigree affected with inherited protein C (PC) deficiency. METHODS: The proband and her family members (7 individuals from 3 generations) were tested for plasma protein C activity (PC:A), protein C antigen (PC:Ag) content and other coagulation indicators. All of the 9 exons and flanking sequences of the proband's PROC gene were amplified by PCR and sequenced. Suspected variants were verified by reverse sequencing of the proband and her family members. Bioinformatic software was used to analyze the pathogenicity and conservation of the variant site. Swiss-PdbViewer was used to analyze the three-dimensional model and the interaction with the mutant amino acid. RESULTS: The PC:A and PC:Ag of the proband, her grandmother, father and elder brother were decreased to 55%, 52%, 48%, 51% and 53%, 55%, 50%, 56%, respectively. Genetic analysis showed that the four individuals have all carried heterozygous c.1318C>T (p.Arg398Cys) missense mutation in exon 9 of the PROC gene. The score of MutationTaster was 0.991, PROVEAN was -3.72, and FATHMM was -2.49, all predicted it to be a harmful mutation. Phylogenetic analysis also showed that Arg398 was weakly conservative among homologous species. Protein model analysis showed that, in the wild type, Arg398 can form a hydrogen bond with Glu341 and Lys395 respectively, when it was mutated to Cys398, the hydrogen bond with Glu341 disappears and an additional hydrogen bond was formed with Lys395, which has changed the spatial structure of the protein. CONCLUSION The heterozygous missense mutation c.1318C>T (p.Arg398Cys) of the PROC gene probably underlay the decreased PC:A and PC:Ag in this pedigree.
