In order to investigate the effects of thyroid hormone on gonadotropin secretion in rat pituitary cells,the cultured rat pituitary cells were exposed to a series of concentrations of T 3 (0, 0 001, 0 01, 0 1, 1 and 10?g/ml). rLH and rFSH were determined after exposure to of T 3 The secretion ability of pituitary cells of rats with different thyroid function was evaluated in vitro. The results showed that high concentrations of T 3 (1 and 10?g/ml) inhibited the secretion of rLH ( P

Objective To establish the RP-HPLC method for determination of Bruchine and Strychine in Pingxiao Tablet. Methods The lichrospher C18 (4.6 mm?250 mm, 5 ?m) was Used as the stationary phase. The Mobile phase consisted of water-acetonitrile (60∶40) with 1.7 g sodium dodecylsulphate and 3.4 g KH2PO4 in 1 000 mL mixture. The Detecting wavelength was 254 nm and flow rate was 1.0 mL/min. The column temperature was 25 ℃. Result The linear ranage of Bruchine and Strychine were 0.102～0.918 ?g and 0.208 ～ 1.872 ?g respectively. The recovery rates of bruchine and strychnine were 101.07% (RSD=2.26%) and 99.29% (RSD=2.79%) respectively. Conclusion This method is realiable and accurate, the method can be applied to determination the contents of Bruchine and Strychine in Pingxiao Tablet.

Objective To investigate the oncologic and reproductive outcomes after progestin treatment of complex endometrial hyperplasia(CEH) and grade 1 endometrial carcinoma(EC).Methods In a retrospective study, data were obtained for patients with CEH or grade 1 EC at presumed stage IA(without myometrial invasion) who wished to preserve fertility and were treated at the Peking Union Medical College Hospital, China, between January 1, 2000 and December 31, 2011.Patients had received oral medroxyprogesterone acetate(250-500 mg/d) or megestrol acetate(160-480 mg/d) for at least 6 months.Results Among 55 included patients, median age was 32 years(range 21-41 years).41(75%) achieved complete response after a median period of 6(3-24) months.Complete response was less frequent among obese than nonobese patients(4/12 [33%] vs 37/43 [86%];P=0.001).Disease recurrence was recorded in 10(24%) patients with complete response;the 5-year recurrence-freesurvival rate was 71%.Among the 33 patients who retained a desire to conceive, 17(52%) became pregnant.Conclusions Fertility-sparing management with oral progestin is effective and safe.Obesity is associated with a lower probability of long-term success.

Objective: To investigate the surgical techniques for establishing the rat model of orthotopic liver transplantation.Methods: On the basis of the double-cuff technique of Kamada,we improved the techniques for the separation and perfusion of the donor liver,the shearing and anastomosis of the superior and inferior caval veins,and the anastomosis of the bile duct.Results: Of the 40 rats that underwent orthotopic liver transplantation,80% survived longer than 24 hours and 70% over 7 days.Conclusion: With extreme patience and carefulness,the operator can successfully establish the rat model of orthotopic liver transplantation by shortening the anhepatic phase with skillful surgical techniques.

OBJECTIVETo explore the mechanism of electroacupuncture at Zusanli (ST 36) on regulation of intestinal inflammatory reaction in rats with acute pancreatitis.

METHODSFifty-four SD rats were randomly divided into a severe acute pancreatitis (SAP) group, an electroacupuncture (EA) group and a sham-operation (SO) group, 18 cases in each group. 3.5% sodium cholate was used to made SAP model by retrograde injecting in cholangiopancreatic duct. After the success of model making, the EA group was treated with EA at bilateral Zusanli (ST 36) for 30 min. The SO group and the SAP group were fixed at the same time for 30 min without treatment. All the rats were killed at 3 h, 6 h and 12 h after modeling in batches. The pathological changes of pancreatic tissue and intestinal epithelium were observed, and the expression of small intestinal occludin protein and nuclear factor kappa-B (NF-kappaB) were detected by immunohistochemical SP method.

RESULTSThe pathologic score and the expression of small intestinal NF-kappaB p65 at 3 h, 6 h and 12 h after modeling in the EA group and the SO group were significantly lower than those in the SAP group (all P < 0.05), and the expression of small intestinal occludin protein in the EA group and the SO group were significantly higher than that in the SAP group (all P < 0.05).

CONCLUSIONElectroacupuncture at Zusanli (ST 36) can alleviate pancreatic injury by reducing the expression of NF-kappaB p65 and enhancing the expression of occludin protein in the intestinal epithelium in the SAP model rats.
