Aim To develop a rapid and inexpensive method for purification of human albumin, a method of immunomagnetic microspheres (IMMS) based on enzyme-linked immunosorbent assay (ELISA)for the purification of human albumin from human serum. Methods Polystyrene magnetic microspheres with carboxyl groups as carriers were prepared, and then the carboxyl groups on the surface of the microspheres were activated by ethylcarbodiimide (EDC). Finally rabbit anti-human serum albumin (HSA) antibodies were covalently bound to it and the complex can specifically capture HSA. After the procedure of capturing HSA, through taking rabbit anti-human albumin protein antibodies as a capture antibody, and goat anti-human albumin protein antibodies as a detection antibody, an ELISA on IMMS was developed, which can determine the recovery yield of HSA from the human serum. Results The result of the experiment was that the recovery of human albumin with IMMS was (86 ± 4) % , and IMMS were reused for two other purifying cycles, the results of which were (69.0 ± 0.6) % and (40.8 ± 0.8) % , and the purity of the product was about 90%. Conclusion The results above prove that the immunomagnetic purifiying strategy was shown to be efficient and offers an new thought for a large scale production of highpurity HSA.

Objective To investigate the relationship between chronic atrophic antral gastritis and the decrease of somatostatin levels in blood and pyloric glands and adaptable protection ability of gastric mucosa.Methods Gastric mucosa biopsy specimen and blood samples were collected to determine the levels of somatostatin(SST)using radioimmunoassay.Histological changes between pre-and post-treatment were observed under light microscope as well as the changes of uhramicrostrucuture under transmission electron microscope.Distribution of SST in gastric mucosa was studied by immunohistochemical staining and then quantified.Results The quantities of gastric antral D cells of chronic atrophic antral gastritis decrease obviously.SST was mainly distributed in D cells of mucosa pyloric gland crypt.The nucleus of mucus epithelial cells in atrophic gastric antral crypt had SST negative staining.Mitochodria swellen,crista broken,rough endoplasmic reticulum distension,mucus secretory granules decreasing,the nuclear membranes disappearing as well as ehromatin integrating could have been seen in the intracytoplasm of mucus epitheliun cells of chronic atrophic gastric antral gastritis.The average level of SST in blood,epithelium and crypt were obviously reduced comparing to that of in the control group.By immunochemistry staining,the SST level in crypt of atrophic gastric antral gastritis Was significantly reduced comparing to that of in control group.With the level of SST in blood＜10 pg/100μl,the probability ratio of emerging atrophy Was 67.7%.Conclusions In case of no systemic inflammatory reaction state,the decreased ability of human pyloric gland D cell in producing SST not only rehtes obviously with human chronic atrophic antral gastritis but also with the weakened adaptable protection ability of gastric mucosa.

Objective To investigate the feasibility of ultrasound-guided percutaneous drainage for the treatment of peripancreatic abscess. Methods The clinical data of 36 patients with peripancreatic abscess who were admitted to the General Hospital of the Chengdu Military Command were retrospectively analyzed. All the puncture sites were designed according to the region, range and shape of the abscess, and then the angle and the direction of the needle penetration were determined according to the spatial relationship between the puncture site and the abscess. Finally, the drainage tubes were placed under the guidance of the ultrasound. Results The technique was successfully performed on all the patients, and 33 patients were cured with the cure rate of 92%.The mean healing time was 37 days. Three patients were converted to laparotomy because of the unsatisfied therapeutic effects. Enterocutaneous fistula was detected in 3 patients after the surgery and they were cured after receiving nonoperative management. All patients were followed up for 3-48 months, and neither residual abscess nor recurrence was detected. Two patients were complicated with type one diabetes, one with dyspepsia, two with gallstone, and they were cured by symptomatic treatment. The body weights of 27 patients were increased compared to those before the operation. Conclusion Ultrasound-guided percutaneous drainage is effective for the treatment of peripancreatic abscess.

Objective To investigate the experience of endoscopic mini-invasive therapy for residual lesions of peripancreatic necrotizing infection with choledocoscopy-assisted debridement technique, and to explore its clinical application value. Methods 71 patients with postoperative surgical drainage and accompanied with residual focus were collected. Choledochoscope was inserted via the drainage sinus, and the focus was observed and necrotic tissue was removed under direct choledochoscopic vision. Results Of the 71 patients who underwent this procedure, 64 were cured (success rate, 90.1%); 3 patients withdraw from treatment due to economic reasons; 4 patients received open surgery after 1 ～ 3 times of choledocoscopy-assisted debridement. The 64 cured patients received 2 ～ 9 times of choledocoscopy-assisted debridement with a mean of 5.1 times. 87.5% patients needed 4 ～ 6 times of procedures. The healing time was 18 ～ 125 days (average 71.3 days). Hemorrhage occurred in 3 patients and digestive tract fistula occurred in 2 patients and were resolved with non-operative management. Conclusions With the help of postoperative established surgical drainage channel, choledochoscopy-assisted debridement could be considered as a safe and effective miniinvasive treatment for residual focus of peripancreatic necrotizing infection, and is worth of clinical application.

Objective To determine plasma soluble HLA-G (sHLA-G) levels in patients with systemic lupus erythematosus (SLE),and to analyze its association with the possibility of organs or systems involvement in lupus patients.Methods Plasma samples were collected from 96 SLE patients and 74 healthy controls,and sHLA-G levels were determined by enzyme-linked immunosorbent assay.The sHLA-G levels in SLE patients and healthy controls were compared with students't-test.The difiefence of clinical and seroimmunological data among the SLE patients was assessed by chi-square test or students't-test.A value of P<0.05 was considered to be significant.Results Plasma concentration of sHLA-G was significanto higher in SLE patients than that in healthy controls[(230±192)U/ml vs(118±38)U/ml,P=0.0001].No relationship between plasma sHLA-G levels and SLE disease activity index(SLEDAI)was found(r=0.157,P=0.141).However,the patients with increased levels of sHLA-G had more severe disease activity (11±5 vs 8±5,P=0.027) and more central nervous system (CNS) involvement (24.2% vs 4.8%,P=0.007) in comparison with patients with normal plasma levels of sHLA-G.Conclusion The increased production sHLA-G,paralleled with more severe disease activity and higher CNS involvement,indicates that sHLA-G may play an important role in the pathogenesis of SLE.
