Postoperative serum triglyceride levels in predicting risk of new-onset diabetes mellitus in patients following liver transplantation / 浙江大学学报·医学版

To investigate the postoperative serum triglyceride (TG) levels in predicting the risk of new-onset diabetes mellitus (NODM) in patients following allogeneic liver transplantation. One hundred and forty three patients undergoing allogeneic liver transplantation in Shanghai General Hospital from July 2007 to July 2014 were enrolled in this study. The NODM developed in 33 patients after liver transplantation. The curve of dynamic TG levels in the early period after liver transplantation was generated. Independent risk factors of NODM were determined by univariate and multivariant logistic regression analyses. The clinical value of TG in predicting NODM was analyzed by area under the ROC curve (AUC). Serum TG levels were gradually rising in the first week and then reached the plateau phase (stable TG, sTG) in patients after surgery. The sTG in NODM group were significantly higher than that in non-NODM group (=-2.31, <0.05). Glucocorticoid therapy (=4.054, <0.01), FK506 drug concentration in the first week after operation (=3.482, <0.05) and sTG (=3.156, <0.05) were independent risk factors of NODM. ROC curve analysis showed that the AUC of sTG in predicting NODM was 0.72. TG shows a gradual recovery process in the early period after liver transplantation, and the higher TG level in stable phase may significantly increase the risk of NODM in patients.

Association of CYP3A5 and C5 polymorphisms with the individual dosage regimen of tacrolimus in Chinese liver transplantation recipients during the early post-transplantation period / 中华器官移植杂志

Objective To investigate the effect of CYP3A5 and C5 gene polymorphisms on the concentration/dose ratio of tacrolimus in Chinese liver transplant patients during the early posttransplantation period.Methods A total of 100 adult patients who underwent primary liver transplantation (LT) were enrolled.Tacrolimus dosage and trough blood concentration were detemined at first week after liver transplantation.Two single-nucleotide polymorphisms were genotyped and analyzed in both donor and recipient groups.The relationship between gene polymorphisms and tacrolimus concentration/dose ratio (C/ D ratio) was analyzed.Results The distribution of allele A in C5 rs17611 was 63.5 ％ among donors and 58.5％ among recipients.For CYP3A5,the rs776746 allele G represented the major alleles in both donors and recipients (71％ and 72％,respectively).The tacrolimus C/D ratio of recipients carrying allele AA in C5 rs17611 was significantly higher than that of recipients carrying the C5 rs17611 allele G.Both donor and recipient CYP3A5 rs776746 polymorphisms were highly correlated with the tacrolimus C/D ratio at first week after liver transplantation.No linkage disequilibrium between CYP3A5 rs776746 and C5 rs17611 polymorphisms was found (D'max =0.392,r2max =0.034).Recipient CYP3A5 rs776746 allele A,C5 rs17611 genotype AA,and donor CYP3A5 rs776746 allele A were associated with rapid tacrolimus metabolism.With increasing number of these alldes,tacrolimus C/D ratio was reduced during the one week after transplantation.Conclusion Recipient C5 rs17611 polymorphism is a new genetic locus that influences tacrolimus metabolism in patients after OLT during the early post-transplantation periocd.

Analysis on curative effects and safety of 2% liranaftate ointment in treating tinea pedis and tinea corporis and cruris

The paper is intended to analyze and evaluate the specific curative effect and safety of 2% liranaftate ointment in treating patients with tinea pedis and tinea cruris. 1,100 cases of patients with tinea pedis and tinea corporis and cruris were selected as research objects and were divided into two groups according to the random number table method. They were treated with different methods: 550 cases of patients were treated with 2% liranaftate ointment for external use in the observation group and the rest 550 cases of patients were treated with 1% bifonazole cream in the control group. The treatment time was two weeks for patients with tinea corporis and cruris and four weeks for those with tinea pedis respectively. Meanwhile, the one-month follow-up visit was conducted among the patients to compare the curative effects of two groups. After the medication, the curative effectiveness rate was 87.65% [482/550] in the observation group, while that was 84.91% [467/550] in the control group. After the average follow-up visits of [15.5 +/- 2.4], the curative effectiveness rate 96.55% [531/550] in the observation group, while that was 91.45% [503/550] in the control group. Two groups of patients recovered well with a low incidence of adverse reactions in the treatment, and the overall curative effect was good with the inter-group difference at P>0.05, so it was without statistical significance. The curative effect of 2% liranaftate ointment is safe and obvious in treating tinea pedis and tinea corporis and cruris, so it is valuable for clinical popularization and application

A case of cutaneous metastasis of osteosarcoma / 中华皮肤科杂志

A 68?year?old female patient was admitted to the hospital for multiple masses in the mouth and lungs as well as on dorsal hands for more than 20 days without obvious subjective symptoms. No abnormalities were found by physical examination. Dermatological examination showed two bean?sized dark?red nodules on the upper jaw as well as one pigeon egg?sized dark?red nodule on the left dorsal hand, and all the nodules were hard with smooth surfaces and limited mobility. Positron emission tomography?computed tomography (PetCT) revealed multiple metastases to the brain, lymph nodes, lungs, gastrointestinal tract, both kidneys, multiple bones and intermuscular tissues. Pathology of nodules from the upper jaw showed lowly differentiated tumor cells with osteoid matrix, chondroid structures and tumor bone in local areas, and immunohistochemical examination of tumor cells found positive staining for S100(focally), vimentin, CD99, P63 and Ki?67(60%), but negative staining for keratin. A diagnosis of osteosarcoma of the right side of the upper jaw was considered. Pathology of nodules from the dorsal hand revealed no obvious abnormalities in the epidermis, while there was a diffuse infiltration of medium?to large?sized histiocyte?like cells in the whole dermis with cell atypia and irregularly red?stained bone matrix and tumor bone in some regions. Immunopathology showed positive staining for Ki67(60%), and negative staining for CD3, CD10, CD20, Bcl?2, and Bcl?6. A diagnosis of cutaneous metastasis of osteosarcoma was made. The patient refused further treatment and died 6 months after the onset of lesions.

OBJECTIVE:To investigate the association of Cytochrome P4503A family polypeptide 5 [(CYP)3A5] and IL-10 poly-morphisms with the concentration/dose(C/D) ratio of tacrolimus in lung transplantation recipients. METHODS:CYP3A5 polymor-phisms at rs774746 and IL-10 polymorphisms at rs1800896 from peripheral blood cell of 51 lung transplant recipients was detected by Se-quenom MassArray iPLEX GOLD system. The relationship between gene polymorphism and tacrolimus C/D ratio was analyzed. RE-SULTS:The tacrolimus C/D ratio of the recipients who carried CYP3A5 rs776746 GG genotype were higher than those with AA+GG genotype,with statistical significance(P<0.01). The tacrolimus C/D ratio of the recipients who carried IL-10 rs1800896 AA genotype were higher than those with AG genotype during 1 week and 2 weeks after transplantation,with statistical significance(P<0.05). Com-bined analysis of these two genes,the tacrolimus C/D ratio of the recipients who carried more fast metabolic alleles were higher than those who didn't carry fast metabolic alleles,with statistical significance(P<0.01). CONCLUSIONS:Determination of recipients CYP3A5 at rs 776746and IL-10 at rs800896 genotype may be performed prospectively to help individualizing tacrolimus dose regimen.

The screening and validating of PLCE1 as a new gene related to the pathogenesis of sporadic colorectal cancer / 中华普通外科杂志

Objective To screen for and validate unknown tumor suppressor genes (TSGs) in sporadic colorectal cancer (CRC) patients.Methods Through loss of heterozygosity (LOH) analysis on chromosome 10 in sporadic CRC,we have found D10S185 (10q23.31-24.33 ) exhibit a higher LOH frequency in our previous study.In present study,we screen for unknown TSGs in this region through the microarray.The expression of the new gene was analyzed by quantitative real-time polymerase chain reaction (qRT-PCR).RT-PCR,immunohistochemistry and Western blot were done in colorectal cancer tissues with their pair-matched normal tissues in 50 cases to validate the results of microarray.Results Through the microarray-based high throughput screening,we found 4 significant down-regulated genes:PLCE1,CPEB3,NKX2-3 and SEMA4G,among them the down-regulation of PLCE1 was most significant.The results of qRTPCR were in relative agreement with the DNA microarray data.RT-PCR,immunohistochemistry and Western blot also showed that the expression of PLCE1 was at low levels in 46％ cancer tissues compared with normal tissues,more frequent in the poor differentiation tumor in patients under age 60 years (P ＜ 0.05 ).Conclusions This study demonstrated that down-regulation of PLCE1 was related to the tumorigenesis of sporadic colorectal cancer.PLCE1 might play a suppressive role in the development of colorectal cancer.

Effects of stably silencing FOXM1 by shRNA on cell growth of hepatocellular carcinoma in vitro / 中华普通外科杂志

Objective To evaluate the effect of sustained silencing Forkhead box Ml (F0XM1) gene by short-hairpin RNA (shRNA) expression vector on cell growth of hepatocelluar carcinoma (HCC) in vitro.Methods Four shRNA expression vectors targeting different sequences of human F0XM1 mRNA were constructed.The expression vector with the best interfering effect and the negative control plasmid were used to transfect HCC cell line QGY-7703, stably transfected cell clones were selected by neomycin (G418).Cell growth was evaluated by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay and colony formation was assessed by clonogenic assay.Cell apoptosis was detected by double staining with APC conjugated Annexin V and PI.Results F0XM1 protein was detected with different levels in all these studied human cell lines.The expression vector shRNA-1026 exhibited excellent interference effect after transient transfection, which showed 38.5% and 53.2% reduction of FOXM1 mRNA and protein level respectively.The growth of QGY-7703 cells was inhibited after stable inhibition of FOXM1 expression by shRNA-1026, which was indicated by decreased absorbance value of the test group after culture for 48, 72 and 96 h compared to control group (t = 10.830,3.578 and 5.734 respectively, P ＜ 0.05).Stable inhibition of F0XM1 also led to reduced colony formation ( t = 5.336, P ＜ 0.05 ) and increased apoptosis of QGY-7703 cells in comparison to control cells (t = 6.827, P ＜ 0.05 ).Conclusions Stable silencing F0XM1 gene by shRNA suppresses the growth of HCC cells in vitro.
