?AIM: To investigate NO levels in tears and anterior chamber inflammation after phacoemulsification and intraocular lens implantation with trabeculectomy through different operative incisions.?METHODS: Totally 49 patients ( 50 eyes ) with primary acute angle - closure glaucoma and cataract were randomly divided to single-incision group and double-incision group. Both were treated by phacoemulsification and intraocular lens implantation and trabeculectomy after routine IOP-lowering drugs treatment. Preoperative and postoperative NO levels in tears were compared, and the aqueous flare and cells were examined using a laser flare-cell meter ( LFCM) .?RESULTS:Postoperative tear NO was 9. 86±0. 78μmol/L in single-incision group , it was 9. 13 ± 0. 67μmol/L in double-incision group, the differences was statistically significant(t=3. 57,P<0. 05). Postoperative aqueous flare values was 62. 42±18. 16 pc/ms in single-incision group;it was 52. 20 ± 17. 57 pc/ms in double-incision group, the differences was statistically significant(t=2. 02, P<0. 05).?CONCLUSION: The early inflammatory injury of double-incision was significantly lower than that of single -incision. It has the advantages of safety. But the surgical skill should be improved to less the injuries caused by operations.

Objective To evaluate the safety and efficacy of ultrosonography-guided two-stage ERCP for management of emergent pancreatobiliary diseases during pregnancy.Methods The clinical data of 32 consecutive pregnant women with suspected emergent pancreatobiliary diseases,who were treated with two-stage ultrasonography-guided ERCP from January 2005 to May 2010,were analyzed retrospectively.All patients were treated with ERCP in two stages. In stage Ⅰ,all the patients underwent ultrasonographyguided biliary cannulation,sphincterotomy with small incision and plastic stent placement during pregnancy.In stage Ⅱ,routine ERCP was performed in two weeks after delivery.The success rate of first ERCP,relief of clinical manifestation,improvement of lab indices,maternal and fetal complications were evaluated.Results All patients presented with fever,biliary colic and jaundice.Abdominal ultrasonography or magnetic resonance cholagiopancreatography (MRCP) revealed dilated common bile duct (CBD) in all patients,with CBD stones in 24 and acute cholangitis in 8.Bile duct cannulation and stent placement were successful in all patients.All patients markedly improved after first ERCP,with laboratory indices significantly improved at 1week after the procedure ( P ＜ 0.01 ).In stage Ⅱ,CBD stones were retrieved in 24 patients under ERCP,including 2 cases of mechanical lithotripsy.Bile duct stenosis was found in 3 patients and plastic stents were replaced.Biliary bleeding occurred in 1 case,mild acute pancreatitis in another,with a complication rate at 6.25％.Patients and babies were followed up for 12 months and found to be healthy.Conclusion Twostage ultrosonography-guided ERCP is safe and effective for pregnant patients with emergent pancreatobiliary diseases,which might be regarded as the first choice for such patients to avoid radiation.

Objective To investigate the litholytic effect of stirring by plastic stem inside biliary tract in large common bile duct (CBD) stone. Methods Forty-five patients with large CBD stones were included in this study (8 with the distal bile duct stricture and 5 with too-small Vater's papilla).Plastic stent of 8.5Fr was inserted into the CBD under the guidance of guide wire in all the 45 patients. Results In 10 of the 45 patients, ERCP showed that there was no stone in CBD 3 months later after stent placement. In 22 cases, repeated ERCP revealed that the stone had become smaller to the extent of more than a half or became stone fragments that were easily extracted by baskets or balloon dilation. Thirteen patients continued to have large stone at the second time ERCP treatment, and a new stent was replaced and follow-up performed by B mode ultrasonography of abdominal region per month. Further endoscopic treatment was performed immediately when the stone became small enough. The percentage of 95.6% (43/45) of large CBD stone were eventually cleared after endoscopic treatment for an average of 2.4 times. There were no severe complications related to ERCP or stent placement. Conclusion Placement of plastic biliary stent is a convenient and effective measure for the treatment of large CBD stones. It is especially appropriate for aged patients of CBD stone of high risk.

Objective To explore the strategies for diagnosis and treatment of anomalous junction of pancreaticobiliary duct (AJPBD) complicated by acute pancreatitis. Methods The clinical dataof 22 patients with abnormal pancreaticobiliary junction were analyzed retrospectively. Results The incidence of acute pancreatitis in this series was 31.8 % (7/22), thereinto, 5 cases(71.4%) in C-Ptype (the common bile duct joining the pancreatic duct) and 2(28.6%) in P-C type (the pancreatic duct joining the common bile duct). Seven patients underwent ERCP+ EST+ ENBD. Two patients with common bile duct stones were treated with stone basket and cholecystectomy was performed in two cases with gallstone. All patients were successfully treated. The follow-up for l year showed that there was no recurrence of pancreatitis. Conclusion Acute pancreatitis usually occurs in patients with AJPBD, especially in C-P type or with gallbladder stone or common bile duct stone. ERCP+EST+ENBD and prophylactic cholecystectomy are effective to prevent and treat acute pancreatitis.

Objective To compare the pathological and serological difference of rheumatoid arthritis (RA) models in severe combined immunodeficiency (SCID) mice transplanted with synovial tissues from patients with rheumatoid arthritis (SCID-HuRAg mice) established either by renal capsule or subcutaneous back heterotopic transplantation. Methods RA synovium and normal human cartilage were co-implanted subcutaneously into the backs or under the renal capsule of 15 SCID mice. Engrafted tissues and serum were taken at the 4th and 8th week after transplantation. Histopathology and ELISA were performed to compare their histological and serological differences with RA. Results The morbidity and taken rate were significantly increased in the subcutaneous back of the mice group than the renal capsule group. The degree of cartilage erosion as well as the titers of serum IgM type rheumatoid factor suggested no significant difference between the two groups of SCID-HuRAg model devel oped by different engraft methods. Conclusion Back subcutaneous transplantation SCID-HuRAg model can be an ideal and stable animal model for studies on the pathogenesis and biotherapy of RA.

OBJECTIVETo observe the therapeutic effect of Hongbeiyegen [the root of Alchornea trewioides(Benth.) Muell.-Arg.] on alcohol-induced liver fibrosis (AF) in rats and explore its mechanism.

METHODSIn rats with AF, the serum levels of transforming growth factor beta1 (TGFbeta1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) were detected along with examination of the changes in serum hyaluronic acid (HA), laminin (LN), procolagen type III (PC III), collagen type IV (C IV), glutamic-pyruvic transaminase (ALT) and glutamic-oxalacetic transaminase (AST) levels.

RESULTSCompared with the control group, Hongbeiyegen could significantly reduce the levels of TGFbeta1, TIMP-1, HA, LN, PC III, CIV, ALT and AST in rats with AF.

CONCLUSIONHongbeiyegen can relieve and ameliorate liver fibrosis possibly by inhibiting the expression of TGFbeta1 and TIMP-1.
