Purpose To investigate estrogen receptor ( ER ) , progesterone receptor ( PR ) expression in PTEN-deficient endometrial carcinoma and to analysis the relationship of PTEN, ER and PR protein expression with histological grade, pathological staging and muscle invasive. Methods Immunohistochemistry EnVision was used to detect the expression of PTEN, ER and PR protein in 100 ca-ses of endometrial carcinoma. Results The rate of PTEN-deficient endometrial carcinoma was 52. 0% (52/100). The expression rate of ER, PR protein on PTEN-deficient endometrial carcinoma was 15. 4% (8/52), 19. 2% (10/52), respectively. And the expression rate of ER, PR protein on PTEN over-expression endometrial carcinoma was 72. 7% (8/11), 63. 6% (7/11), respectively. The rate of PTEN, ER and PR expression types shown PTEN-ER-PR- was 42. 0% (42/100), which was higher than other types (P <0. 05). Different PTEN, ER and PR expression types were well correlated with histological grade and pathological staging (P<0. 05), but not with muscle invasive. Conclusion Combined detection of PTEN, ER and PR may have an important reference value for prog-nosis and treatment of endometrial carcinoma.

Objective To explore the effect of 1a,25(OH)2 D3 on circadian clock gene expressions in cardiac myocytes.Methods Cultured cardiac myocytes isolated from 7 -day -old Sprague -Dawley(SD)rats were identified by immunofluorescence.The medium including 1a,25 (OH)2 D3 (final concentrations were 0 nmol/L,1 nmol/L, 10 nmol/L,50 nmol/L and 100 nmol/L)were added to primary myocardial cells to culture for 2 h and then total RNA was extracted.Real -time polymerase chain reaction (RT -PCR)was applied to analyze myocardial cells circadian clock gene (Bmal1,Per2,Rev -erba)transcript levels to determine optimum concentration of 1a,25(OH)2 D3 .Then, the primary myocardial cells cultured for 72 h were divided into 3 groups:the control group was of serum -free culture medium;serum shock group was of DMEMcontaining 50%volume fraction of horse serum cultured 2 h;1a,25(OH)2 D3 treatment group receiving 1a,25 (OH)2 D3 at optimal concentration cultured 2 h.The cells were collected at 7 time points (0 h,4 h,8 h,12 h,16 h,20 h,24 h)and then total RNA was extracted.RT -PCR was applied to analyze circa-dian clock gene (Bmal1,Per2,Rev -erba)transcript levels in the myocardial cells.Results In the presence of 50 nmol/L 1 a,25(OH)2 D3 ,the Bmal1 mRNA expression showed the highest level,but the Per2 and Rev -erba mRNA expression levels were minimum.Compared with the control group,both 1a,25 (OH)2 D3 treatment group and serum shock group caused day -cycle rhythmic oscillation in circadian clock genes(Bmal1,Per2,Rev -erba)in the cardiac myocytes.And the expressions pattern of Bmal1 and Per2 genes were in the opposite phase.While Bmal1 gene expres-sion appeared at peak at 12 h,Per2 gene expression appeared in a trough.Expression of Rev -erba gene trend began to rise at 8 h,and the highest expression level appeared at 12 -16 h.Conclusions 1a,25(OH)2 D3 can affect Bmal1, Per2 and Rev -erba mRNA expressions of circadian clock genes in the cardiac myocytes.

Objective To explore the basic biological characteristics of lncRNA -uc.1 67,and its spatial dis-tribution,temporal expression pattern during the mouse embryonic development.Methods The UCSC genome browser of ENCODE was used to analyze preliminary bioinformatics of lncRNAs.Real -time (RT)-PCR was applied to detect the expression of uc.1 67 and neighboring genes in the embryonic mouse heart in different stages (P7.5,P1 1 .5,P1 4.5, P1 8.5).Dimethyl sulphoxide was used to induce P1 9 cell differentiation into the cardiomyocytes.RT -PCR was applied to detect the expression changes in uc.1 67 and neighboring genes on differential day 0,4,6,8 and 1 0.Results Full -length of human uc.167 was 201 bp,and human uc.167 was located in the genome 5q14.3 (chr5:88179623 -881 79824,GRCh37 /hg1 9).uc.1 67 mainly expressed in the ventricular muscle tissue.The expression of uc.1 67 was gradually decreased in the mouse embryonic heart development process(P7.5:1 .000 ±0.1 00,P1 1 .5:0.71 4 ±0.1 07, P1 4.5:0.393 ±0.043,P1 8.5:0.1 25 ±0.01 3),while the expression of its neighboring Mef2c gene was gradually in-creased(P7.5:1 .081 ±0.1 1 8,P1 1 .5:2.340 ±0.351 ,P1 4.5:3.958 ±0.542,P1 8.5:9.361 ±0.722),which showed an opposite trend.The expression of uc.1 67 during P1 9 cell differentiation into cardiomyocytes showed a an increase at first and then a decreasepattern,and the highest level expression of uc.1 67 was on differential day 4(d0:1 .071 ± 0.1 1 7,d4:4.71 4 ±0.501 ,d6:3.572 ±0.41 4,d8:2.550 ±0.31 4,d1 0:0.786 ±0.085).The expression of neigh-boring gene Mef2c was in an opposite trend(d0:1 .01 2 ±0.041 ,d4:0.353 ±0.037,d6:2.470 ±0.329,d8:6.706 ± 0.682,d1 0:7.765 ±0.705).Conclusions It is suggested that uc.1 67 may take part in the process of embryonic heart development and may play a role through negatively regulating its neighboring gene Mef2c.

Objective:To retrospectively evaluate the prognostic risk factors of T1-2 stage breast cancer patients with one to three positive node(s) and their effects on the benefits of post-mastectomy radiation therapy (PMRT). Methods:We retrospectively analyzed 457 breast cancer patients with T1-2 stage and one to three positive axillary lymph nodes treated in our hospital between 2000 and 2002. The independent prognostic factors of the patients were calculated by the Cox proportional hazards model. The patients were fur-ther classified into high-risk and low-risk subgroups according to the risk factors to explore the benefit of PMRT on the prognosis of dif-ferent subgroups using survival analysis. Results:PMRT was not an independent beneficial factor of overall survival (OS) (HR=0.949;CI:0.435-2.074;P=0.896) or loco-regional recurrent free survival (LRRFS) (HR=0.611;CI:0.231-1.614;P=0.320) in all patients. Ex-tracapsular extension (ECE) and pathological grades were independent prognostic risk factors, and the benefits of PMRT were signifi-cantly different on the prognosis of high-risk subgroup patients (group ECE+OS:P=0.020, LRRFS:P=0.014;group GradeⅢOS:P=0.002, LRRFS:P<0.001). Meanwhile, PMRT failed to prolong the OS and LRRFS of low-risk subgroup patients (group ECE+OS:P=0.353, LRRFS:P=0.796;group GradeⅠtoⅡOS:P=0.267, LRRFS:P=0.589). Conclusion:ECE and gradeⅢwere the independent risk factors of death and loco-regional recurrence in the T1-2 breast cancer patients with one to three positive lymph node(s). PMRT was an effective adjuvant therapy to improve the prognosis of patients with high-risk factors. However, the benefit of PMRT had no sig-nificance in patients with ECE-or gradeⅠ-Ⅱ.

OBJECTIVETo assess the association of CYP2C19 gene polymorphisms with the incidence of ischemic stroke among patients receiving clopidogrel therapy following coronary stenting for coronary artery disease.

METHODSClinical data of patients receiving clopidogrel therapy after coronary stenting were retrospectively studied. For a case-control study, 137 patients with acute cerebral infarction and 122 non-stroke patients were selected. Based on the variants of the CYP2C19 gene detected by a DNA microarray assay, the patients were further divided into the wild-type group(CYP2C19*1/*1) and mutant group(defined by the presence of at least one loss-of-function allele, including CYP2C19*1/*2, CYP2C19*1/*3, CYP2C19*2/*2, CYP2C19*2/*3 and CYP2C19*3/*3). The incidences of ischemic stroke in the two groups were compared through a chi-square analysis. The influence of CYP2C19 gene polymorphisms and clopidogrel therapy on the incidence of ischemic stroke was analyzed through multivariable logistic regression.

RESULTSA total of 259 patients were enrolled. The case and control groups showed no difference in terms of gender and age. There were 123 cases (47.5%) in the CYP2C19 wild-type group and 136 cases (52.5%) in the mutant group. The incidence of ischemic stroke of mutant group was significantly higher than that of wild-type group (59.9% vs. 44.3%, X2=6.398, P=0.042). Multivariate analysis revealed that loss-of-function polymorphisms of the CYP2C19 gene carried a 1.13 times greater risk for ischemic stroke compared to wild-type genotype (OR=2.13, 95%CI: 1.23-3.71).

CONCLUSIONThe efficacy of clopidogrel for the prevention of ischemic stroke in post-coronary stent patients may be reduced by the insufficiency of the CYP2C19 gene. The dosage of clopidogrel therapy should be adjusted based on its polymorphisms.

OBJECTIVETo evaluate the therapeutic effect of integrative Chinese and Western medicine in treating mid-advanced crescentic nephritis (MACN).

METHODSThirty-two patients, their diagnosis was confirmed as MACN by renal biopsy, were divided, adopting randomized, controlled method, into two groups, the treated group and the control group, they were all, excepting one, treated with impact therapy of methyl-prednisolone followed with oral intake of prednisone, to part of them cyclophosphamide or mycophenolate mofetil was given in addition, to those with hypo-hemoglobin (< 90 g/L), subcutaneous injection of erythropoietin was administered. Decoction of Qingre Huoxue recipe (QHR), consisted of oldenlandia herb 30 g, honey-suckle stem 30 g, violet herb 30 g, red peony root 15 g, rehmannia root 15 g, solomonseal rhizome 15 g, asiabell root 30 g, red sage root 30 g, prepared rhubarb 12 g and giant-hyssop herb 12 g, were additionally given one dose per day to patients in the treated group. The renal function, improvement of anemia and immunosuppressive agents needed in patients were observed after 3 months treatment.

RESULTSAfter treatment, renal function was improved in both groups, but the effect in the treated group was better than that in the control group (P < 0.05). Anemia was partially alleviated in the two groups with no significant difference. The dosage of glucocorticoids used in the treated group was obviously lesser than that used in the control group (P < 0.01).

CONCLUSIONIntegrative Chinese and western medicine could treat crescentic nephritis to obtain good effect, and reduce the quantity of glucocorticoid necessity for treatment.
