Objective To explore the role of estradiol decline in the early luteal phase (the 2nd day after oocyte retrieval) in the prediction of in-vitro fertilization outcomes. Methods A total of 236 cases under in vitro fertilization-embryo transfer (IVF-ET)/ intracytoplasmic sperm injection-embryo transfer(ICSI-ET) cycles were included in this retrospective study of their medical records. The cases were divided into three groups according to the levels of estradiol decline on the 2nd day following OPU: group A (n = 70) with the decline rate of less than 70%, group B (n=114) with the decline rate of 70%~80%and group C (n=52) at the decline rate of more than 80%. The comparisons were done among the three groups in terms of the number of oocyte retrieval, the rate of fertilization, the rate of best oocytes and the rate of miscarriage. Results There were no significant differences statistically in the number of oocyte retrieval, the rate of fertilization, the rate of best oocytes and the rate of miscarriage (P > 0.05). But the rates of clinical pregnancy rate in groups A and B were significantly higher than that in group C (68.6% and 68.4% vs. 44.2%) (P < 0.05). Conclusion The levels of estradiol declines in the early luteal phase may be important in the prediction of IVF outcomes.

Nowadays partial splenic embolization (PSE) is an important therapeutic means to treat secondary hypersplenism caused by portal hypertension. By reducing the splenic blood flow and increasing hepatic blood supply, the peripheral blood picture and the liver function indexes as well as the portal hypertension can be effectively improved. This article aims mainly to make a comprehensive review on the therapeutic effect and mechanism of PSE, its clinical efficacy, as well as the factors affecting the clinical results, and to discuss the postoperative complications, the advantages and disadvantages of different embolic materials.

Objective To investigate the clinical effect of interventional embolization in the treatment of intractable hematuria after percutaneous nephrolithotripsy. Methods A retrospective analysis of the First Affili?ated Hospital of Kunming Medical University from February 2014 to March 2016 after percutaneous nephrolithot?omy appears intractable hematuria patients in 36 cases was conducted. All patients were treated with conservative treatment but invalid,then lesion was confirmed by renal artery angiography,after that,line embosphere micro?spheres or polyvinyl alcohol particles combined with spring ring interventional the treatment was conduc?ted. Postoperative urine color changes, postoperative complications and follow?up were observed whether have bleeding again. Results ( 1) The success rate:36 cases patients all with successful embolization,the symptoms of hematuria in 1?3 days gradually disappeared,and the effective rate was 100%. ( 2) Complications:the compli?cations after operation in 10 patients appeared different degree of embolism syndrome,given analgesic and antie?metic,the symptoms gradually ease after treatment. One case patient with a transient increase of creatinine after operation,renal function returned to normal 7 days after the treatment. ( 3) Follow up:there was no recurrence of hemorrhage after 3?6 months of follow?up. Conclusion Transcatheter embolization in the treatment of intracta?ble hematuria has definite curative effect,less trauma,high safety,less complications and faster postoperative re?covery.

Objective To observe the effect of Dahuangzhechongwan on protein excretion, serum cholesterol, TXB_2 and 6-keto-PGF_(1?) in rats with adriamycin-induced nephrosclerosis. Methods The rats received twice-intravenous injections of adriamycin after one kidney was removed, and were fed with hyperlipide food to establish an animal model for diffusion mesangioproliferation following with focal segmental glomerulosclerosis. The rats were randomly divided into shame-operated group, adriamycin nephrosclerosis group, Dahuangzhechongwan group, benazepril group. Urinary protein excretion, blood fat, TXB_2 and 6-keto-PGF_(1?) were observed. Result Proteinuria extract was decreased, the plasma cholesterol was significantly lower, the level of TXB_2 was cut down and 6-Ket-PGF_(1?) was increased by Dahuangzhechongwan. Conclusion Dahuangzhechongwan has the role of simutianeous application of elimination and tonification, promoting the circulation of Qi and blood, eliminating blood stasis, improving the hemodynamics. Dahuangzhechongwan has the renal protection on rat with adriamycin-induced nephrosclerosis, the mechanism may be relate with adjusting the balance of TXB_2 and 6-keto-PGF_(1?).

Objective:To construct an immune inhibitor of new TNF-?,C-terminal sequence of new rhTNF-? was replaced with sequence of T-help cell of hen egg-white lysozyme(HEL).Methods:The rhTNF-? mutant was cloned 、expressed and purified.Results:The DNA sequencing analysis showed that the C-terminal sequence of new rhTNF-? mutant was correct.The mutant was inserted into pBV220 expression vector .After the recombinant bacteria was incubated at 42℃ for 4 h,a new band of the protein with relative molecular weight of 1.7 kD was shown on the gel.The band amounted to 30 % of total bacteria protein.Western blot showed that the mutant protein could associated with anti-TNF-? antibody.After the protein was purified by through a column of Q-Sepharose Fast Flow, the purity of the protein was above 90%.The biological activity of the protein was measured with L929 cells.The result showed that biological activity of the protein was totally lost.Conclusion:The experimental evidence demonstrated that the construction of new rhTNF-? mutant was successful.The mutant not only can be associated with anti-TNF-? antibody, but also lose the biological activity of original TNF-?.

OBJECTIVE: To study the status quo and future trend of digestive system drugs used in our hospital. METHO-DS: The digestive system drugs used in our hospital between 2001 and 2005 were analyzed retrospectively in respect to drug kinds, consumption sum, DDDs, daily costs etc. RESULTS: Drugs for peptic ulcer and hepatobiliary diseases took a big proportion and experienced a year- on- year increase. No significant change was noted for the top 10 drugs on the lists of DDDs and consumption sum before and after the medical insurance reform, but their order changed a little. The DDDs of most of the cheap and effective drugs increased after the medical insurance reform. CONCLUSION: The consumption of antiulcer drugs and drugs for hepatobiliary diseases in our hospital assume an increasing tendency.

Objective To introduce a method for fast establishment of pig models with secondary hypersplenism, and using this model to study the effect of radiofrequency ablation (RFA). Methods Congestive splenomegaly was created by CT- guided percutaneous embolization of splenic vein and its collateral branches in pigs. Then radiofrequency ablation was employed in the models to observe the changes of peripheral blood as well as the spleen changes in its morphology and histopathology. The blood cell count for peripheral venous blood was determined once a week, and the spleen size was measured by CT scanning. Results One week after splenic vein embolization, the counts of peripheral erythrocytes and platelets showed a reduction, which became more obvious in three weeks (P < 0.05). Erythropenia, thrombocytopenia and splenomegaly could last for over six weeks. At the second week after the procedure , pathologically the spleen assumed passive congestion appearance. The thermal energy produced by radiofrequency ablation could cause local splenic coagulation necrosis, splenic vessels occlusion and splenic thrombotic infarction due to diffuse micro-vascular thrombosis. Conclusion To establish an animal model with secondary hypersplenism, the method of CT-guided percutaneous embolism of splenic vein is simple and reliable. The animal models can be used for surgical or interventional researches. Radiofrequency ablation is an effective intervention means.
