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.

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.

OBJECTIVETo observe preventive and therapeutic effects of Tanshinone IIA (T II A) on oxaliplatin induced peripheral neuropathy (OlPN) and to explore its effects on the expression of calcitonin gene related peptide (CGRP) and never growth factor (NGF).

METHODSTotally 36 phase II - III patients with malignant tumor of digestive tract undergoing chemotherapy program with oxaliplatin, were equally assigned to the T II A group (using THA at 80 mg/day 1 day before oxaliplatin chemotherapy for 3 successive days) and the control group (using chemotherapy program with oxaliplatin alone) by segmented randomization. After 4 cycles of chemotherapy, the incidence degree and incidence of OlPN were evaluated. Sensory nerve conduction velocity (SNCV) and motor nerve conduction velocity ( MNCV) were tested by EMG evoked potential device. Serum levels of CGRP and NGF were also detected in the two groups before and after chemotherapy. The correlation of serum levels of CGRP and NGF to OIPN was assessed using linear correlation analysis.

RESULTSAfter chemotherapy the OlPN incidence was 27.8% (5/18 cases) in the T II A group, obviously lower than that in the control group (55.6%, 10/18 cases; P < 0.05). Compared with before treatment in the same group, SNCV and MNCV of common peroneal nerve were slowed down, serum NGF levels decreased, and serum CGRP levels obviously increased in the two groups (all P < 0.05). Compared with the control group after treatment, SNCV and MNCV of common peroneal nerve were obviously accelerated, serum NGF levels increased, and serum CGRP levels obviously decreased in the THA group (all P < 0.05). Results of linear correlation analysis indicated serum NGF level was negatively correlated with peripheral neuropathy (PN), serum CGRP expression was positively correlated with neurotoxicity (P < 0.05).

CONCLUSIONT II A could reduce the incidence of OlPN, which might be associated with inhibiting the expression of CGRP and up-regulating NGF activities.

Objective To demonstrate the histology in acellular dermal matrix(ADM)after being transplanted in vivo over time. Methods Forty male SD rats were recruited for the experiment. Subcutaneous implantation of an 1 cm × 1 cm ADM was given in the left sides on the back of the rat for the experimental group, while only dissection and suturing were performed in right side of the back for the control group. All the animals will be sacrificed at appointed time after operation, Five ADM samples were harvested in each time point. The content and proportion of collagen type were examined with HE staining, Picrosirius staining, Masson′s trichrome staining, and Immunohistochemical staining (targets: pan macrophage, M1 macrophage and M2 macrophage). Results All rats survived after operative without any complications. Significant differences of thickness were not observed at the end of 5 months; HE scores suggested that ADM increased in cell infiltration scores in 2 weeks before the plateau , vascularity also showed a similar trend; Collagen trichrome staining showed a substantial increase in density of collagen bundles with time. The comparison of the proportion of collagen among days showed significant differences (P < 0.05). Immunohistochemical staining of M1 and M2 showed that macrophages had distinct polarization profiles in materials. Furthermore, the comparison of M1 vs M2 response associated with different materials showed significant differences in all time points (P < 0.05). Conclusions The chemically cross-linked ADM could keep long time in the body; ADM significantly stimulated proinflammatory of M2 differentiation from M1 in constructive remodeling.

[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.
