Journal of Endocrine Surgery 2015;(3):242-245
Objective To analyze the different procedures and their clinical effects on treatment for pan-creatic pseudocyst( PPC) .Methods The management and outcome of 78 patients with PPC from Jan.2002 to Jun.2012 were retrospectively analyzed.Results 20 patients underwent conservative treatment and the pseudo-cysts absorbed spontaneously during follow up.Invasive procedures were performed in 58 cases, including percu-taneous catheter drainage in 3 cases with 1 postoperative pancreatic leakage and 1 postoperative pancreatic ab-scess;PPC external drainage in 5 cases with 2 postoperative pancreatic leakage and 1 postoperative bleeding;pancreatic pseudocyst stomach anastomosis in 15 cases with 1 postoperative gastrointestinal bleeding;Roux-en-Y cystjejunostomy in 29 cases with 2 gastrointestinal bleeding;cystduodenostomy in 2 cases;pancreatic pseudocyst excision in 2 cases with 1 postoperative pancreatic leakage; and laparoscopic cystogastrostomy in 2 cases.Con-clusions At present, there are various treatment options for pancreatic pseudocyst and it is necessary to choose treatment strategy according to patient's condition.Internal drainage is still the primary option of surgical proce-dures in treatment for pancreatic pseudocyst.

This article was aimed to study macroporous resin adsorption kinetics for effective extraction of water ex-tracting with alcohol precipitating in cicada slough. PT, APTT and the coagulation-fibrinolysis dynamic figure were taken as main indexes, which were combined with static and dynamic tests, to select the best macroporous resin to separate and purify the extraction. Adsorption kinetics curve was drawn to fit the adsorption kinetics model. The re-sults showed that NKA-9 macroporous resin was more effective in separating and purifying effective extraction than others. The adsorption dynamic behavior was well described by the pseudo-second-order kinetics equation. It was concluded that the adsorption rate was mainly controlled by the intraparticle diffusion.

AIM: To observe the effects of valsartan on the cardiac hypertrophy and the expression of PTEN in spontaneously hypertensive rats (SHR). METHODS: Twenty 12-week-old male SHR were randomly divided into 2 groups:SHR positive control group and valsartan treating group ( 30 mg?kg -1?d -1). 10 homogenous Wistar-kyoto (WKY) rats were served as normal control group. Blood pressure and the ratio of left ventricular weight to body weight(LVW/BW)of rats were monitored periodically during the 8-weeks studies. Expression of PTEN in cardiac myocytes was determined by immunohistochemistry. RESULTS: Blood pressure and LVW/BW increased in the valsartan group more than those in the SHR control group, and the expression of PTEN in cardiac myocytes in valsartan group increased more than that in the SHR control group, but the indexes were lower than those in the WKY group. CONCLUSION: Valsartan can not only inhibit the progression of cardiac hypertrophy in spontaneously hypertensive rats, but also increase the expression of PTEN. PTEN may play a role in cardiac hypertrophy.

Objective To investigate healthy status and disease distribution of couples through analysing the results of pre‐preg‐nancy laboratory examination and to explore high risk factors ,in order to provide scientific references for the realization of eugenics . Methods The routine blood test ,serum markers of hepatitis B ,five items(TORCH) examination ,detection of female vaginal secre‐tions were carried out in 8 313 couples planning pregnancy from 2013 to 2014 ,and the results of pre‐pregnancy health examination were analysed and evaluated .Results The thyroid dysfunction accounted for 17 .43% of all women undergoing examination ,which was the most common disease .Among items carried out in all couples ,thalassemia and positive of hepatitis B surface antigen were the most common ,accounted for 10 .20% and 9 .94% respectively .Conclusion The pre‐pregnancy health examination could screen high risk factors ,which is benefit for guiding eugenics and effectively reducing the birth defects and adverse pregnancy and is a sig‐nificant measure for eugenics .

Prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), plasma fibrino-gen (FIB), platelet aggregation rate and blood clots-fibrinolytic dynamic figure were taken as indexes in the evalua-tion of anticoagulant activity in vivo of active component F2-2 from Eupolyphaga seu Steleophaga. After 5 days of hypodermic injection of adrenaline, the rat model of acute blood stasis was established. Indexes were determined af-ter the model rats were treated with an intragastric administration of F2-2 for 9 days. The results showed that com-pared with the model group, PT/APTT was prolonged, FIB content was decreased, platelet aggregation rate and the largest of blood coagulation were declined after 9 days of intragastric administration in the model group. However, there was no difference on TT. It was concluded that the anticoagulant component F2-2 separated from E. seu Steleophaga showed favorable anticoagulant activity in vivo. However, its mechanism remained unknown and request-ed further researches.

A Staphylococcus aureus strain, designated zfb, was isolated from a clinical bovine mastitis case of a dairy cow. Staphylococcus aureus zfb can have resistance to methicillin and no lipase contrast by ATCC 25923. The production of the capsule was assessed by the diffuse colonial morphology in serumsoft agar. A mouse infection model was used to determine the LD50 and the invasiveness of SA zfb. The LD50 of SA 25923 to experimental mice was 10-2.5/mL, and the LD50 of SA zfb to experimental mice was 10-4.33/mL. The purpose to detect characteristics of SA zfb makes it an interesting candidate for the preparation and assay of an avirulent mutants against staphylococcal infections and further investigate on pathogenic mechanism.

Objective Deleting the cysteine-rich region (22-37 amino acids)of HIV-1 HXB2 Tat protein(whole length is 101 amino acids) to improve its stability and expression level in E.coli and to analyze the immunogenicity of Tat protein without the cystein-rich region [Tat(△C)protein]. Methods Tat DNA deleted the cysteine-rich region (64-111 nucleotides), named as Tat(△C)DNA, was obtained in vitro by PCR and cloned into pET-32a vector. pET-32a-Tat(△C)plasmid and the pET-32a-Tat plasmid were established and transformed into E.coli BL21(DE3) strains respectively to express and purify the protein. Three rabbits were vaccinated with pET-32a-Tat(△C)protein, then testify the reactivity of sera from rabbits by ELISA and Western blot. Results The dense of the purified pET-32a-Tat(△C)protein was 7.12 mg/ml,which was greatly more than pET-32a-Tat protein(1.50 mg/ml). Dimer of pET-32a-Tat protein can be observed just after the protein purification and stored at 25℃ and 4℃ for 7 days, but dimer of pET-32a-Tat(△C)protein was not formed at the same condition. Experimental rabbits were immunized with pET-32a-Tat(△C)protein and produced high titre of anti-pET-32a-Tat(△C)serum(1∶320 000), the antibody can react specifically with Tat(△C)protein, Tat protein (1-101 AA)and synthetic Tat(1-86 AA) protein. Deletion mutation of the cysteine-rich region of Tat protein was first performed in the study. Conclusion The expression level in E.coli and the stability of Tat protein deleted the cysteine-rich region can be increased greatly, and the protein remains good immunogenicity. The results may provide a novel antigen for further development of HIV-1 Tat vaccine.
