Objective To investigate the effects of CO 2 pneumoperitoneum during laparoscopic cholecystectomy (LC) on pulmonary functions in chronic pulmonary failure rabbits and their mechanisms. Methods A total of 50 healthy male rabbits ( oryctolagus cuniculus ) were randomly divided into 4 groups: normal control group (N 0: n=5, no pneumoperitoneum), experimental control group (T 0: n=5, no pneumoperitoneum), 10 mmHg experimental group (T 10 : n=20, 10 mmHg pneumoperitoneum) and 15 mmHg experimental group (T 15 : n=20, 15 mmHg pneumoperitoneum). After the successful establishment of emphysema rabbit models, CO 2 pneumoperitoneum was conducted and maintained for 2 hours at the pressure of 10 mmHg (1.33 kPa) and 15 mmHg (2.00 kPa), respectively. Pulmonary functions (total respiratory resistance, central resistance and total airway resistance) of the 4 groups were measured by pulse oscillation technique before and after the pneumoperitoneum, respectively. Results Total respiratory resistance, central resistance and total airway resistance increased after the establishment of emphysema models. And they decreased at the end of pneumoperitoneum compared with those before pneumoperitoneum ( q=17.824, P

This study is performed to analyze the anti-liver fibrosis effect of the fusion protein of human serum albumin and extracellular domain of transforming growth factor beta type II receptor(eTGFBR2)in vivo to looking for the more stable anti-liver fibrosis drug. The mice model of liver fibrosis was constructed by CCl4 induction and the following groups are included in the study: the control group, CCl4 model group, the positive control group, eTGFBR2 treatment group, HSA-eTGFBR2 treatment group, and HSA group. Hematoxylin eosin staining, serum liver function index detection, and western blot are used to identify the anti-liver fibrosis activities. The results showed that: (1)CCl4 caused liver structure disorder, hepatocellular necrosis, collagen fibers proliferation, and induced liver fibrosis at last; (2)HSA-eTGFBR2 and its monomer drug improved the symptoms of liver fibrosis significantly, as well as reduced the damage of liver cells and collagen deposition, and recovered the liver basic structure to normal. Both of HSA-eTGFBR2 and its monomer drug improved liver function and reduced the expression level of liver fibrosis marker α-SMA and COL I. Moreover, the anti-liver fibrosis effect of the fusion protein is comparable to the monomer drug. In contrast, the albumin had no effect on therapeutic effect; (3)Reducing the injection frequency of HSA-eTGFBR2 achieved the comparable effects to the monomer drug with the normal injection frequency. In summary, the fusion protein HSA-eTGFBR2 has good anti-liver fibrosis effect. In addition, reducing the injection frequency of the fusion protein could also achieve the comparable treatment with the monomer drug, indicating that the fusion protein is stable and has longer half-lives and then a relatively positive application prospect in future.

AlM: To observe clinical effect of vitrectomy with intravitreal ranibizumab for the treatment of diabetic retinopathy ( DR) .
METHODS:From February 2011 to February 2013, there were 90 cases in our hospital diabetic retinopathy patients withvitrectomy surgery. lt was randomly divided into observation group ( 45 cases ) and control group ( 45 cases ) . Two groups of patients were performed vitrectomy. Patients in observation group were injected intravitreal ranibizumab before surgery, then vitrectomy was underwent for diabetic retinopathy. Vitrectomy was only underwent in control group.
RESULTS:The patients in observation group with good effect accounting for 71% (32/45) and good rate was 89%(40/45 ), which were significantly higher than that in control group 51% ( 23/45 ) , 71% ( 32/45 ) . Differences were statistically significant ( P < 0. 05 ). Amount of bleeding was 9. 64 ± 2. 27mL, intraocular pressure was 13. 64 ± 3. 27mmHg. lt was significantly less than that in control group 10. 21 ± 3. 14mL, 16. 00 ± 3. 14mmHg. Differences were statistically significant (P<0. 05).
CONCLUSlON: The vitrectomy with intravitreal ranibizumab treatment of diabetic retinopathy can not only reduce blood loss, but also reduce edema and improve effectiveness and safety. lt's worth recommending for clinical practice.

Objective Based on detection of the soluble LAIR-1 (sLAIR-1) and sIL-2R in the bile from recipient after liver transplant, the role of sLAIR-1 and sIL-2R in graft acute rejection were analyzed. Methods Bile sLAIR-1 level and sIL-2R were determined by double mAb sandwich enzyme linked immunosorbent assay in 55 cases of liver transplantation. Results In 22 recipients with normal graft function, sLAIR-1 and sIL-2R were detected at low level in the bile. In the 29 cases of liver acute rejection (AR), significant increase of bile sIL-2R level was detected on the lst and 2nd d before final diagnosis. With the effective methylprednisolone pulse therapy, sIL-2R level was decreased significantly on the 3rd d. On the other hand, remarkable increase of bile sLAIR-1 was found on the lst,2nd and 3rd d before final diagnosis. After of methylprednisolone pulse therapy for 3 d, bile sLAIR-1resturned to the control level. Conclusion Both bile sIL-2R and sLAIR-1 are detected at high level in the recipients suffering from liver acute rejection. The level of bile sLAIR-1 changes dramatically and responsively according to liver acute rejection. Therefore, detecting these two markers synergistically may be a promising monitor for rejection after liver transplantation.

Objective To study the expression of plasma membrane Ca2 + -ATPase isoforms 1 -4 and the splice variants at sites A and C in the neonatal rat vestibular organ.Methods Ten rats at postnatal 2 days (P2 ) were decapitated and their vestibular organs (macula utriculi and macula sacculi)were isolated.The total proteins of the vestibular organs were extracted.The expression of PMCA1-4 splice variants at sites A and C was detected by RT-PCR.Results The splice variants of PMCA1-4 at sites A and C in macula utriculi and macula sacculi of neo-natal rat vestibular organs were PMCA1x/b,PMCA2w/(a,b),PMCA3z/(a,b,c)and PMCA4 (x,z)/b.Conclusion The splice variants at sites A and C among PMCA1,PMCA2,PMCA3 and PMCA4 were different in the vestibu-lar organs of neonatal rats,which could be explained that macula utriculi and macula sacculi had different require-ments of Ca2 + turning for these PMCA isoforms.

Objective To summarize the etiology,classification and clinical characteristics of congenital bile duct dilatation and our experience in its diagnosis and troatment.Methods The clinical data of 37 cases of congenital bile duct dilatation were retrospectively analyzed.Results The 37 cases included TypeⅠin 31 cases,Type Ⅱ in 1 case,Type Ⅳ in 4 cases,and Type Ⅴ in 1case.All of the patients underwent operative treatment.External drainage of was done in 2 cases,Roux-en-y cystojejunostomy in 3 cases,exeisison of cyst cyst and Roux-en-y hepaticojejunostomy in 31 cases and left hepatectomy in 1case with malignant change of cyst.Five cases had postoperative complications that recovered with non-operative treatment.Thirty-two cases were cured.There were no operative deaths.Conclusions Congenital bile duct dilatation should be treated as soon as possible.Excision of the cyst and Roux-en-y hepaticojejunostomy can reduce long-term postoperative complications and is the rational treatment for congenital bile duct dilatation.

Objective To study the expression of plasma membrane Ca2+-ATPase isoforms 1~3 (PMCA 1~3 )in the basilar membrane (BM)of the neonatal rat cochlea by Western blot.The PMCA2 content in single BM of the neonatal rat was also examined.Methods Four rats at postnatal 2 days (P2)and 8 days (P8)were respective-ly decapitated and their BMs were isolated.The total proteins of BMs were extracted.The 20μg total proteins were respectively loaded to the gel.The expression of PMCA1-3 was detected by Western blot.Likewise,3μg total proteins from P2 and P8 rat BM were loaded.The expression of PMCA2 was detected by Western blot.Four rats at P8 were decapitated and their BM was isolated.The 5μg,10μg and 20μg total proteins of P8 rat BM were added to the gel and 100 ng,400 ng and 800 ng bovine serum albumin (BSA)were also loaded as reference.After electro-phoresis,the gel was separated into two parts.One part was used for SYPRO staining and the other part was used for PMCA2 detection by Western blot.Results In the 20μg BM total proteins of P2 and P8 rats,the expression of PMCA1 was weak (0.126±0.024,0.131±0.012,respectively),PMCA2 was strong (4.16±0.528,4.25±0.319, respectively),and PMCA3 was barely expressed (0 ).There was a statistical difference among PMCA1 ,PMCA2 and PMCA3(P<0.05).In the 3μg BM total proteins of P2 and P8 rats,the expression of PMCA2 in P8 (4.571± 0.336)was higher than P2 (3.622±0.285).There was a statistical difference(P<0.05).The PMCA2 content in the BM of a P8 rat was about 2 .5 ng.Conclusion There was a different-level expression of PMCA1~3 in the neonatal rat BM with highest expression of PMCA2 ,which could be explained that cochlear hair cells had different requirements of Ca2+ turning for these PMCA isoforms.
