Objective: To investigate the effects of AG, an iNOS inhibitor on microcirculation of the septic shock rabbits. Method: The white rabbits were infused endotoxin(LPS, 300?g. kg~(-1)in lh. Two hours after the MAP de creased to 60% of the baseline, the rabbits were grouped randomly as L-NAME(n=6.30 mg. kg~(-1))I. V. group and AG(n=6,20 mg. kg~(-1)) I. V. group. Result: Two hours after MAP decreased, the blood velocity decreased, the arterio lar of mesenterium dilated by 18%(P

Objective: To investigate the effects of selective NOS inhibitor aminoguanidine (AG) on endotoxintreated rat aorta (AO) and pulmonary artery (PA) in vitro. Method: The reaction to noradrenaline (NE) (10~(-9)-10~(-4)mmol/L) was measured in the vessels with complete endothelium, then the vessels were divided into 8 groups after incubated in LPS(300ng/ml)for 4 hours. Each group was incubated with AG(100?mol/L)or L-NAME (300?mol/L)for 20, or 60min, respectively. Result: Both AO and PA showed hyporeaetivity to NE after incubated in LPS. and the reactivity of AO and PA to L-NAME and AG increased significantly after incubated in them for 60min or 20min. The sen sitivities of AO to AG,AO and PA to L-NAME increased greatly. AO had a higher reactivity to AG in 60min than in 20min. L-NAME caused earlier and greater contraction than AG in both 60 min and 20 min groups. Conclusion: LNAME and AG can both increase the decreased reactivities of AO and PA to NE. AG only increases the AO sensitivity.

OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.

ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To study the express of matrix metalloproteinase(MMP)-2 and tissue inhibitor of metalloproteinase(TIMP)-2 protein in human endometrial carcinoma. Methods The Immunohistochemistry was used to measure the MMP-2, TIMP-2 in endometrial carcinoma tissue of 40 patients, the atypical hyperplasia of 12 samples and the normal endometrium of 12 samples. Results The positive express of MMP-2 and TIMP-2 in the normal endometrium , atypical hyperplasia and endometrial carcinoma was increased gradually. In endometrial carcinoma, with progression of clinical stage and decrease of histological grade as well as deepening of cancer invasion, the ratio of MMP-2/TIMP-2 was increased. Conclusions The expression of MMP-2 and TIMP-2 were connected with endometrial carcinoma. The imbalance of MMP-2/TIMP-2 in the endometrial cancer might be one of the pathogenesis and development.

Background and purpose:P38 mitogen-activated protein kinase (P38MAPK) signal transduction pathway is involved in occurrence, development and transfer process in a wide variety of tumors. Urokinase-type plasminogen activator (uPA) plays an important role in tumor invasion and metastasis. This study aimed to explore the clinical signiifcance of the P38MAPK signaling pathway and the expression of uPA in ovarian cancer.Methods:The expressions of uPA, P38MAPK, ERK and AKT were detected in 49 cases of cervical adenocarcinoma by immunohistochemistry. The expressions of uPA and P38MAPK were detected by Western blot in ovarian cancer cell lines HO8910, HO-8910PM, SKOV3 and CAOV3. The changes of uPA and P38MAPK were detected by SB203580, a speciifc inhibitor of P38MAPK signal transduction pathway.Results:The result of immunohistochemical method showed that positive expression rates for uPA, P38MAPK, ERK and AKT were 61.22%, 57.14%, 53.06% and 55.10%, respectively. The expression of the uPA was positively correlated with the P38MAPK (r=0.865,P=0.001), and related with clinicopathologic stage, differentiated degree, lymph node metastasis, but not related with age and histologic type (P>0.05). The expressions of AKT and ERK were related with the lymph node metastasis and greater omentum metastasis(P<0.05), but not related with age and histologic type (P>0.05). The expression of uPA in HO-8910PM was higher than that in ovarian cancer cell lines HO8910, SKOV3 and CAOV3, and the expression of uPA reduced when the P38MAPK signal transduction pathway was cut off by the SB203580. The expressions of P38MAPK and uPA were negatively correlated with the prognosis of ovarian cancer (Log-rank=3.897 and 11.044,P=0.048 and 0.001). Conclusion:The P38MAPK signal transduction pathway was activated in ovarian cancer. The activated P38MAPK signal transduction pathway can raise the expression of uPA, which may contribute to the development of ovarian cancer. The result indicates that the P38MAPK signal transduction pathway and uPA might play an important role in the invasion and metastasis of ovarian cancer. P38MAPK and uPA might be useful markers for evaluating prognosis of ovarian cancer.
