Objective:To observe the effect of addition and subtraction therapy of Guyinjian on oocyte quality, pregnancy outcome and ovarian reserve function in patients with poor ovarian response (POR) with kidney Yin deficiency syndrome. Method:Ninety patients were randomly divided into control group (45 cases) and observation group (45 cases) by random number table. The patients in both groups got antagonist. Based on such treatment, the patients in observation received additional addition and subtraction therapy of Guyinjian. The using time and amount of gonadotropin (Gn), ovum taking cycle, cycle canceling rate, fertilization rate, available embryo rate, quality embryo rate, ovulation cycle clinical pregnancy rate were recorded. Levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), serum estradiol (E2) and endometrial thickness, anti mullerian hormone (AMH), resistance index (RI), pulsation index (PI), end diastolic velocity (EDV) and peak systolic velocity (PSV) were detected. Ratio of PSV/EDV (S/D) was calculated, and scores of kidney yin deficiency syndrome were graded before and after treatment. Result:Total amount of Gn in observation group was less than that in control group (PP2 were higher than those in control group (PPPχ2=5.124, Pχ2=5.767, PPPPPConclusion:Addition and subtraction therapy of Guyinjian can increase ovarian blood supply, improve high ovarian reserve function, reduce Gn consumption, increase number of acquired eggs, alleviate symptoms of kidney yin deficiency, and can ameliorate ovarian responsiveness and pregnancy outcome.

<p><b>OBJECTIVE</b>To explore the regulatory mechanism of inducible nitric oxide synthase (NOS-2) expression related to proliferation of Tca8113 cells.</p><p><b>METHODS</b>RNAi mediated by short hairpin RNAs was utilized to knock down NOS-2, protein kinase C (PKC)-α, PKC-β and PKC-δ. Griess Reagent played a significant role on the detection of NO product after NOS-2 silence. The cell proliferation was determined by CCK8 method. Quantitative real-time polymerase chain reaction (q-PCR) was recruited to check the mRNA level of NOS-2, PKC-α, PKC-β and PKC-δ after treated by a variety of ways. Eventually, the measure of phosphorylation of extracellular regulated protein kinases (ERK)1/2 was performed by Western blotting in PMA-treated Tca8113 cells.</p><p><b>RESULTS</b>The cell viability of Tca8113 decreased obviously after transfected with NOS-2 siRNA (P<0.01). PKC reduced the expression level of NOS-2 mRNA (P<0.05). PKC-α, PKC-β and PKC-δ worked together to regulate the level of NOS-2 mRNA (P<0.01). Motigen-activated protein kinase kinase (MEK)/ERK signaling pathway regulated the level of NOS-2 mRNA negatively (P<0.05). PKC down regulated the level of NOS-2 mRNA through MEK/ERK signaling pathway (P<0.05).</p><p><b>CONCLUSIONS</b>PKC regulates the mRNA level of NOS-2 related to proliferation through MEK/ERK signaling pathway in Tca8113 cells.</p>
