AIM: To evaluate the efficacy and complications of intravitreal injection of triamcinolone acetonide ( TA ) for the treatment of macular edema caused by pre-retinal membrane of the macular.
METHODS: Totally 23 patients ( 24 eyes ) with macular edema caused by pre-retinal membrane of the macular were treated withintravitreal injection of 4mg TA. Best-corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , slit - lamp examination, fundus fluorescein angiography ( FFA ) and optical coherence tomography (OCT) were performed before and after treatment. The SPSS 12. 0 software was used for statistical analysis.
RESULTS: After 10, 30, 90d of treatment of TA, as compared with before treatment, visual acuity improved significantly ( P<0. 05 ), and central macular thickness (CMT) was significantly thinner (P<0. 01). The average central macular thickness decreased from 522 ± 126μm before treatment to 264±115μm, 245±128μm, 286±131μm at 10, 30, 90d after treatment. Macular edema reduced. IOP increased in 7 eyes ( 29%) , one cataract case, no other complications associated with vitreous injection.
CONCLUSION: Intravitreal injection of TA in the treatment of macular edema caused by pre - retinal membrane of the macular is simple, safe and easy to operate. It can quickly reduce macular edema, and improve the visual acuity in the short term. Part of patients may recur after injection in the first half of the year.

OBJECTIVE To study the effect of Qing Yi Tang on acute pancreatitis(AP),especially AP complicated with endotoxemia and its possible mechanism.METHODS Fourty Wistar rats were divided into 5 groups including group A(the control group),group B(the AP group),group C(the AP group treated with Qing Yi Tang),group D(the AP group treated with LPS) and group E(the AP group treated with LPS + Qing Yi Tang).Pathological damage of pancreatic tissue was scored with HE staining.The mRNA expression of TNF-? was measured with semi-quantitative RT-PCR,and activation of NF-?B was detected with flow cytometry(FCM) assay.RESULTS It was shown in results that the expression of TNF-? mRNA,activation of NF-?B and pathological damage of the group B were all obviously higher than those of the group A.After treated with LPS which might promote the activation of NF-?B,there was seen the further rise of the activation of NF-?B,expression of TNF-? mRNA and pathological damage.When Qing Yi Tang intervention was applied,the activation of NF-?B and the expression of TNF-? mRNA could be remarkably relieved,so did the pathological damage of pancreas.CONCLUSIONS Qing Yi Tang may be applied to decrease activation of NF-?B and the expression of TNF-? so as to treat AP or AP with endotoxemia.

OBJECTIVETo compare the difference in the efficacy on thoracic facet joint disorder between the combined therapy of electroacupuncture and manual reduction and the simple manual reduction.

METHODSOne hundred and sixty patients were randomized into an electroacupuncture and manual manipulation group (group A) and a simple manual manipulation group (group B), 80 cases in each one. In the group A, Ashi points and three pairs of Jiaji (EX-B 2) bilateral to the painful sites were selected. The perpendicular puncture was used at Ashi points, the oblique puncture was used at Jiaji (EX-B 2) and connected with electric stimulation for 20 min, additionally, the corresponding manual reduction was adopted at the sites of facet joint disorder. In the group B, the simple manual reduction was applied to the affected sites. Acupuncture was given once every day, the manual reduction was applied once every 10 days. The treatment of 10 days made one session. The efficacy was analyzed statistically at the end of two sessions of treatment. Before and after treatment, McGill pain scale was adopted for the value statistical analysis. PRI score, VAS score and PPI score of patients were calculated before and after treatment and compared in the two groups. The efficacy was compared between the two groups.

RESULTSThe curative rate was 56.3% (45/80) in the group A, which was better than 18.8% (15/80) in the group B (P< 0.01). The total effective rate was 95.0% (76/80) in the group A, which was better than 76.3% (61/80) in the group B (P<0.01). The scores of PRI, VAS and PPI after treatment were all improved significantly in the two groups (all P<0.05), in which, the results in the group A were better than those in the group B (PRI: 4.00 +/- 0.97 vs 5.44 +/- 1.16, VAS: 3.29 +/- 0.72 vs 3.87 +/- 0.81, PPI: 1.07 +/- 0.74 vs 1.64 +/- 0.90, all P<0.05).

CONCLUSIONThe combined therapy of electroacupuncture and manual manipulation achieves the superior efficacy on thoracic facet joint disorder as compared with the simple manual manipulation. The combined therapy relieves the symptoms of thoracic facet joint disorder and reduces the severity of disorder.

Advanced gastric cancer is usually dealt with D2 radical dissection. There are different opinions as to whether it is necessary to perform D3 radical lymphadenectomy.Some scholars thought that properly enlarged radical dissection can improve long-term outcomes for the treatment of advanced gastric cancer.In recent years,laparoscopic D1 and D2 radical dissection of gastric cancer could be carried out in many hospitals.However,the technique and related skills for performing D3 radical lymphadeneetomy through laparoscope remains to be explored.Based on our previous experiences,D3 radical lymphadeneetomy using artery suspension method and medial-to-lateral approach for advanced gastric cancer is proved to be safe and feasihle.

Objective:To investigate the phenotype and function of the intestinal γδT lymphocytes in post-infectious irritable bowel syndrome mouse model. Methods:The mouse model for post-infectious irritable bowel syndrome was established by the infection with trichinella spiralis. The intestinal inflammation,abdominal withdrawal reflex( AWR) and colon transportation test were observed. 2 and 8 weeks later,the animals were sacrificed and the lymphocytes in the intestinal lymph nodes and spleen were collected,from which the γδT lymphocytes were isolated and purified by monoclonal antibody-immuno-microbeads method. The functions of the purified γδT lymphocytes were evaluated,including proliferation by 3 HTdR;CD69,CD62L molecule staining by flow cytometry. Furthermore,the con-centration of cytokine IL-17 and IFN-γ in the supernatant of the cultured γδT lymphocytes were detected by ELISA. Results: At 2nd weeks after infection,significant intestinal inflammation was observed,with increasingγδT lymphocytes,proliferating and activating with increasing production of IL-17. At 8th weeks after infection, the intestinal inflammation disappeared, whereas the number of γδT lymphocytes remained increasing,also with proliferating and activating with increasing production of IL-17. Meanwhile,the mice show higher AWR score and Bristol score. Conclusion: γδT lymphocytes could participate in the pathogenesis of PI-IBS via their proliferation,activation and production of IL-17.

OBJECTIVETo investigate the expression of discoidin domain receptor 2 (DDR2) of fibroblast-like synovial cells in improved adjuvant-induced animal (AIA) model for rheumatoid arthritis (RA) and to provide evidence for DDR2's antagonist use clinically.

METHODSAIA was modified by administrating 0.1 mL of complete Freund's adjuvant (CFA, mixed with 5 mg Bacillus Calmette-Guerin vaccine/mL) into rats' right hind paws and 0.125 mL tumor necrosis factor-alpha (2 U/mL) into right ankles and subpatellar fatty tissue. The expression of DDR2 in fibroblast-like synovial cells was assessed using immunohistochemistry, immunofluorescence histochemistry, and in situ hybridization methods. Levels of anti-collagen II antibody were measured using enzyme-linked immunosorbent assay.

RESULTSGiven the terms mentioned above, we found a more practical rat model, apparently decreasing immunization time (average 3-5 days). DDR2 can be detected upon the 15th day of immunization; expression gradually increased with time going on, and reaching a peak 35 days after immunization before gradually decreasing. Serum anti-collagen II antibody showed similar expression patterns as DDR2, but reached peak later than DDR2, about 40 days after immunization.

CONCLUSIONRegular expression of DDR2 in animal models infers its important role in the pathological process of RA.

BackgroundThe influence of glaucoma on the quality of life in patients is of increasing concern for ophthalmologists in recent years. However,some studies demonstrated that different types of questionnaires about quality of life have various disadvantages. Therefore, to accurately and fully assess the influencing factors of quality of life in glaucoma patients is very important. ObjectiveThe present study was to survey the self-reported visionrelated quality of life(QOL) in glaucoma patients by means of utility analysis and to tentatively analyze its influencing factors. Methods Patients with glaucoma were recruited from a single tertiary ophthalmic department. Standard face-to-face interviews were conducted. Utility values of linear rating scale ( RS ) and time trade-off ( TTO ) were calculated to evaluate the self-reported vision-related QOL of the patients. The correlations of the utility values with the patients' general and ophthalmologic characteristics were also analyzed. This survey was approved by the Ethic Committee of Beijing Tongren Hospital. Oral informed consent was obtained from the subjects before the study.ResultsA cross-sectional study was designed. A total of 86 glaucoma patients were enrolled in this study with 62 male and 24 female, with a mean age of 44. 67 years old. The mean utility values measured by RS and TTO were 0. 62± 0. 19 and 0. 77 ± 0. 12, respectively, and no evidential correlation was found between these two values ( r =0. 074, P=0. 499 ). The RS value was associated with daily visual acuity,mean deviation(MD) of visual field and the history of trabeculectomy. Neither daily visual acuity nor MD showed a significant correlation with the TTO value. Age, work status and educational background contributed to higher utility value for the TTO method. After adjusting for age, work status and educational level,patients with visual acuity in the worse-seeing eye better than 0. 3 showed a higher TTO value than those with less than 0. 3. Conclusions Utility analysis possesses the advantages of convenience and sensitivity. RS utility value is easily affected by the Objective visual status and surgery history in glaucomatous patients,which reflects the subjective assessment of patients'visual quality. However, TTO value is primarily associated with age,work status and education level rather than visual function in glaucoma patients,which is therefore subjective assessment of the disease-related quality of life. These Results indicate that visual function impairment is not a determining factor for the QOL of glaucoma patients.
