Acute pancreatitis is a common serious disease, and considered to be inflammatory disturbance course. The early storm of proinflammatory cytokine releasing evokes systemic inflammatorome response syndrome (SIRS) ,and leads to multiple organ dysfunction syndrome(MOPS). At the late phase, because massive of antiin-flammatory cytokines initiate compensatory anti-inflammatory response syndrome ( CARS), the body immune func-tions suffer suppressed and result in infection or toxemia. So reestablishing baulance of SIRS/CARS has considera-ble clinical meaning to the AP patient morbidity. In this article, we will overview the relevant factors and mecha-nisms of the SIRS/CARS induced by AP.

Both aspirin and angiotensin converting enzyme(ACE)inhi bi tors are often used concomitantly in patients with cardiovascular disease.The s afety of the combination has been questioned. The potential antagonistic interac tions between ACE inhibitors and aspirin has become the focus of both increasing research and intense debate,with conflicting conclusions havin g been reported in the literature.We reviewed systematically available literatu re on the interactions between ACE inhibitors and aspirin in hyper- tension,acute myocardial infarction and congestive heart failure and found that further trials are needed to shed light on the effects and mechanism of interaction between these drugs.

Lysimachiae Herba and Desmodii Styracifolii Herba are common traditional Chinese medicines for treating lithiasis. Both of them have efficacies of clearing heat, diuresis and eliminating calculi. However, there are some differences in their clinic applications. The former is mainly used to treat hepatolithiasis, gallstones, jaundice, stranguria and gout; Whereas the latter is mainly used to treat urinary calculus. In this paper, the pharmacological effects of Lysimachiae Herba and Desmodii Styracifolii Herba on removing calculus, choleresis, anti-inflammation and oxidation resistance were compared and analyzed based on document retrieval. In conclusion, both of them show the preventive and therapeutic effects on kidney stones and gallstones. Particularly, Desmodii Styracifolii Herba has a better effect in treating the kidney stones, while Lysimachiae Herba has a better effect in treating cholesterol gallstones.

OBJECTIVETo investigate the short-term clinical outcome of unicompartmental knee arthroplasty for the treatment of spontaneous osteonecrosis of the knee.

METHODSFrom September 2013 to April 2014,5 patients with spontaneous osteonecrosis of the knee underwent unicompartmental knee arthroplasty, included 3 males and 2 females, aged from 65 to 80 years old with an average of 74 years. The courses of disease was from 1 to 6 years with the mean of 3 years. According to the radiographic staging criteria of Koshino, 1 case was stage II, 2 cases were stage III, 2 cases were stage IV. Clinical effects were assessed by VAS score, HSS score, and knee range of motion, tibiofemoral angle before and after operation.

RESULTSAll the patients were followed up from 6 to 7 months with an average of 6.4 months. All incisions obtained primary healing, and there were no complications such as infection, thrombosis, fracture of lower limbs. All 5 patients' pain relieved and their knee function improved significantly after operation, but knee range of motion had no obviously improved. Postoperative HSS scores, VAS scores, tibiofemoral angle were significantly improved than that of preoperative.

CONCLUSIONThe short-term effect of unicompartmental knee arthroplasty in treating spontaneous osteonecrosis of the knee is satisfactory.

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.

Bioimprinting is a new developed technique to improve the characteristics of enzymes.Bioimprinting by lauric acid was conducted to improve the esterification activity of lipase PS in sol-gel immobilization process with methyltrimethoxysila(MTMS) and tetramethoxysila(TMOS) as the precursors.Results generated by checking the esterification activity and scanning electron microscope showed that bioimprinting can enhance the specific activity and thermal stability of lipase PS.The bioimprinting system was optimized by orthogonal experiment,and the optimal condition for lipase bioimprinting is water/silane molar ration(R) 12,polyethylene glycol(PEG) 120?l,and lauric acid 0.15 mmol.Compared with the free enzyme and the non-imprinted enzymes,the specific activity of imprinted enzymes has been improved 44.3 fold and 2.4 fold,respectively.Imprinted lipase show better thermal stability,and the relative activity is 58% after incubated in 80 ℃ for 0.5 h,while no activity was detected for the free enzyme.

Aim To study inhibitory effect of 5-fluorouracil encapsulated by galactosylceramide liposomes (5-Fu-GCL)on 5-Fu-resistent HepG_2 cells and its mechanisms. Methods Inhibitory effect of 5-Fu-GCL on established model of 5-Fu-resistant HepG_2 cells was assessed with MTT assay in vitro. The concentration-time course of 5-Fu-GCL in intracellular fluid was detected with high performance liquid chromatography (HPLC). Thymidylic acid synthase (TS) expression was observed with immunohistochemical method,and NO content was determined with chemical method. Results Obvious inhibitory effects of 5-Fu-GCL (75,150,300,600,1200?mol?L-1) on 5-Fu-resistant HepG_2 cells were observed with IC_ 50 of 158.6 ?mol?L-1,far lower than that of free 5-Fu (400.9 ?mol?L-1). 5-Fu-GCL (300 ?mol?L-1) inhibited 5-Fu-resistant HepG_2 cells in a time-dependent manner,and the inhibitory effect of 5-Fu-GCL was stronger than that of free 5-Fu during 12～48 h. Compared with free 5-Fu,5-Fu-GCL (300 ?mol?L-1) increased the content of intracellular fluid in 5-Fu-resistant HepG_2 cells. 5-Fu-GCL(62.5,300,1200 ?mol?L-1) not only inhibited the expression of TS,but also increased the production of NO in 5-Fu-resistant HepG_2 cells,and these effects of 5-Fu-GCL(300,1200 ?mol?L-1) were stronger than those of free 5-Fu. Conclusion 5-Fu-GCL has inhibitory effect on 5-Fu-resistant HepG_2 cells. The effect may be related to the increased concentration of 5-Fu-GCL in intracellular fluid,inhibited expression of TS and increased production of NO.

Aim To study the effect of the total flavonoids of turpinia arguta seen (TFS) on immune function of rats with adjuvant arthritis. Methods Adjuvant arthritis (AA) was induced on d0 by intradermal injection of Complete Freund′s Adjuvant (FCA), containing 10 mg heat-inactive BCG in 1ml paraffin oil. On d 28 after immunization, AA rats were killed by cervical decollation. Immune cells (splenocytes and peritoneal macrophages) were obtained, then cultured in vitro with TFS. Some immune indexes were detected respectively such as the splenocytes proliferation and the productions of IL-1 and IL-2 were measured by the method of cell proliferation, the production of prostaglandin E2 was determined by radioimmunoassay. Results Compared with normal groups, the response of splenocytes to ConA and LPS was lowered, IL-2 syn-thesis was decreased, and IL-1 and PGE_2 released from PM? were elevated. TFS (10~ -8 ~10~ -4 mg?L~ -1 ) not only increased splenocytes proliferation, which induced by ConA and LPS, and IL-2 production of splenocytes, but also reduced the elevated productions of IL-1 and PGE_2 released from peritoned macrophate in AA rats in vitro. Conculsion TFS could adjust abnormal immune function in AA rats.
