To investigate the clinical effect of tonifying the kidney and promoting blood circulation to promote oocyte decoction in the treatment of anovulatory infertility caused by polycystic ovary syndrome. Sixty cases were selected from the out-patient department of Xiyuan hospital of China academy of Chinese medical sciences and the Chinese academy of traditional Chinese medicine, Chinese medicine out-patient department. Sixty patients with PCOS patients were randomly divided into the treatment group and the control group, with 30 cases and 30 cases respectively. The treatment group was given decoction of the reinforcing kidney, activating blood circulation and ovarian stimulation compound recipe. The control group was treated with clomiphene. Through the treatment of 1-2 courses, in the treatment group the pregnancy rate was 56.67%, the ovulation rate 61%; in control group of clomiphene citrate ovulation ratepregnancy rate was 30% , 72.84% of ovulation rate. The difference was significant between two groups (P < 0.05), the pregnancy rate in the treatment group was higher than the control group. The treatment group has regulatory effect on FSH, LH and their ratio, and increase E2 level, decrease T, PRL, INS and other hormone levels, contributing to the mature development of the follicles and endometrium growth, increase the ovulation rate and pregnancy rate. The control group on FSH, E2 increased, LH, T, PRL and INS showed no obvious effect.

Objective To observe the characteristics of different blood perfusion in renal cell carcinoma by contrast-enhanced ultrasound and prove its diagnostic value.Methods One hundred and six cases of renal cell carcinoma confirmed by patholog were involved,and were divided into three groups:clear cell carcinoma group,papillary cell carcinoma group,and chromophobe cell carcinoma group.Their imaging characteristics were observed.Time-intensity curve was analyzed by using QLab software.The difference of time of beginning to increase (△AT =ATrenal cell carcinoma-AT surrounding normal renal parenchyma) and the difference of peak intensity(△PI =PIrenal cell carcinoma-PIsurrounding normal renal parenhyma) in three groups were compared.Results △AT and △PI in clear cell carcinoma group were different from those in the papillary cell carcinoma group and chromophobe cell carcinoma group (P ＜0.05).The difference between papillary carcinoma group and chromophobe carcinoma group was not significant (P ＞0.05).Contrast agent filled very fast in most clear cell carcinomas,filled speed and time to peak were early or synchronously with the surrounding renal tissue.Compared with renal papillary carcinoma and chromophobe carcinoma group,clear cell carcinoma group showed a high peak intensity and part of the surroundings appeared high increasing signs,like of a ring.Contrast agents filled slow in papillary carcinomas group and chromophobe carcinomas group,and the peak intensities were low.Conclasions Contrast enhanced ultrasound can provide important clinical value for the diagnosis of renal cell carcinoma and subtype diagnosis.

control group,and showed statistically significant difference among three groups(P0.05).Conclusion Excessive fluorine intake may cause unbalanced free radical metabolism.It suggests that the intervention on fluorine intake will contribute to resume the balance of oxidation.

Objective To investigate the association between apolipoprotein J(ApoJ)gene polymorphism and type 2 diabetes mellitus(T2DM).Methods The exons 3、4、7、8 of ApoJ gene were screened by polymerase chain reaction-denaturing gradient gel electrophoresis(PCR-DGGE)in 61 type 2 DM patients and 60 healthy control subjects of Chinese population.Abnormal bands were sequenced.Results The deletion/insertion polymorphism site in exon 7 of the ApoJ gene on two subject groups had significant difference (P0.05).Conclusion ApoJ of exon 7 deletion/insertion polymorphism is one of the genetic marker of 2 DM and the ApoJ polymorphism may be associated with 2 DM.

To investigate the induction of apoptosis of mouse colonic adenocarcinoma CT26 cells by recombinant Clostridium difficile toxin B (rTcdB), CT26 cells were exposed to different concentrations of rTcd B. Inhibition of cell proliferation was measured by MTT assay. The activation of Caspase 3 was measured by colorimetric method. Cell morphological analysis and flow cytometry were performed to confirm cell apoptosis. rTcd B inhibited the proliferation of CT26 cells in a timeand dose-dependent manner. Caspase 3 activity in CT26 cells was elevated remarkably after rTcd B exposure for 6 h, 12 h, 18 h or 24 h, as compared with the control group. Morphological changes were observed by fluorescence microscopy. The exposure of rTcd B to CT26 cells induced a timeand dose-dependent apoptotic cell death as determined by flow cytometry analysis. The results showed that recombinant Clostridium difficile toxin B induced apoptosis of CT26 cells.

AlM:To investigate the effects of pirfenidone ( PFD) on the proliferation and transfomring growth factor-β1 ( TGF-β1 ) expression in vitro culture rat corneal stromal cells.METHODS: Corneal stromal cells from 8 to 10wk SD rats were isolated, cultured and treated with different concentrations of PFD 0mg/mL (control group), 0. 15mg/mL (experimental group▏), 0. 3mg/mL (experimental group‖), 1mg/mL (experimental group Ⅲ) for 48h. CCK-8 assay was performed to assess cell proliferation, while immunocytochemistry and Western Blot were used to detect the expression of ki-67 and TGF-β1 expression, respectively. RESULTS: Compared with control group, PFD significantly inhibited the proliferation in a dose -dependent manner ( all P < 0. 05 ), so was protein expression of ki-67. PFD significantly down-regulated the expression of TGF-β1 in a dose-dependent manner (P<0. 05).CONCLUSlON: Pirfenidone can significantly inhibit the proliferation of rat corneal stromal cell by down regulating TGF-β1 expression, therefore, it has potential prospect in lightening the corneal wound healing reaction.

Objective To investigate the protective effects of MicroRNA-214 on myocardial injury induced by myocardial ischemia and reperfusion,as well as the regulation mechanism of PI3K and its downstream protein kinase B(AKT)and FoxO1(PI3K / AKT / FoxO1).Methods Wistar rats were randomly divided into 4 groups:sham operation group(Sham group),myocardial ischemia reperfusion injury(IRI)group(IRI group),microRNA-214+sham operation group(MS group),microRNA-214+IRI group(MI group),(n=10,each).The cardiac function was detected at 6 h after ischemia-reperfusion operation.And blood lactate dehydrogenase(LDH),creatine kinase(CK),creatine phosphate kinase isoforms MB(CK-MB),cardiac troponin T(cTnT),serum B natriuretic peptide(pro-BNP)in plasma were detected by enzyme-linked immunosorbent assay(ELISA).Interleukin 10(IL-10),Interleukin 6(IL-6)and tumor necrosis factor α(TNF-α)were assayed.Pathological changes of myocardial tissue were detected by HE and Masson.The expression of microRNA-214 was detected by RT-PCR.The expression of Bax,Caspase-3,BCl2,PI3K,Akt,FoxO1 was detected by Western Blot.Results Compared with Sham group,IRI group showed a significantly increases in myocardial injury parameters of LDH,CK,IL-6 and TNF concentration in plasma,and a significantly reduced concentration of IL-10(P<0.05).And compared with Sham group,MI group showed a significantly increased expression of microRNA-214(P<0.05)and showed a significantly increased myocardial parameters of Bax,Caspase-3,PI3K,Akt protein,and a decreased level of BCl2,FoxO1(P<0.05).Compared with IRI group,microRNA-21 group showed a reduced myocardial ischemia-reperfusion-induced myocardial injury in rats and a reduced plasma concentration of LDH,CK,IL-6 and TNF-alpha,a inhibited expression of caspase-3,Bax,myocardial PI3K and Akt,and a promoted expression of BCl2 and FoxO1 protein(P<0.05).Conclusions MicroRNA-214 reduces the myocardial injury induced by myocardial ischemia-reperfusion through PI3K/Akt signaling pathway.

[Summary] We investigated a 12-year-old girl with elevated serum FT3 , FT4 , and TSH levels. The sequence of thyroid hormone receptorβ( TRβ) exons revealed a CCT→ACT transition mutation at nucleotide 453 site within exon10,whichresultedinthesubstitutionofcytosinetoadenosinein(P453T). Pituitarymagneticresonanceimage showed a pituitary micoradenoma. The patient underwent transsphenoidal pituitary adenomectomy. Pathological results exhibited positive TSH-β, GH, prolactin, ACTH, and α-HCG staining for the tumor. This is the first case report with thyroid hormone resistance syndrome and thyrotropin-secreting adenoma.
