BACKGROUND:The degradation of extracellular matrix, which is mediated by matrix metal oproteinases, plays a crucial role in the corneal neovascularization. Tissue factor pathway inhibitor 2, a new type serine proteinase inhibitor, can effectively inhibit the activity of matrix metal oproteinases.
OBJECTIVE:To elucidate the effect of tissue factor pathway inhibitor 2 on the expressions of matrix metal oproteinases in keratocytes in vitro.
METHODS:Rabbit keratocytes were primarily cultured and subcultured in vitro. Plasmid vector pBos-Cite-neo/TFPI-2 was transfected into keratocytes with Lipofectamine 2000. The positive cells were selected using G418.
RESULTS AND CONCLUSION:The results of reverse transcription-polymerase chain reaction, western blot analysis and gelatinase zymography analysis showed that, expression of mRNA and protein of tissue factor pathway inhibitor 2 was upregulated in the transfected keratocytes (P<0.05), while activity of matrix metal oproteinase 1 and 2 was significantly decreased (P<0.05). Experimental findings indicate that that tissue factor pathway inhibitor 2 strongly inhibits the activity of matrix metal oproteinase 1 and 2 in keratocytes.

Objective To analyze the epidemic characteristics of mushroom poisoning incident in order to find the regularity of outbreak and provide the fundamental guidelines of prophylaxis,control,diagnosis and treatment.Methods According to the reported information from the Management Information System of Public Health Emergency in China mainland,the area-time distribution of mushroom poisoning incidents from 2004 to 2014 was analyzed,and the descriptive analysis of mushrooms poisoning incidents including causes,places,occupation of victims and incidents identification were made from 2010 to 2014.Results In China (excluding Hong Kong,Macao and Taiwan),the top five provinces of mushroom poisoning incidents were Yunnan,Guizhou,Sichuan,Guangxi and Hunan.The epidemic peak was reached in summer-autumn season.The major and significant incidents accounted for 76.56％ of overall mushroom poisoning incidents,and the fatality rate of 3 701 patients accounted for 21.24％ (786 deaths).The causes were mistaking poisonous mushrooms as edible mushrooms or purchasing poisonous mushrooms in the market by accident.About 87.50％ incidents happened at home.Farmers,workers,children and students were easily subjected to mushroom poisoning because of their large range of activities,strong curiosity and lacking related ability for distinguishing edible mushroom from poisonous mushrooms.No identification was done in 200 mushroom poisoning incidents from 2010 to 2014,which accounted for 92.59％ of mushroom poisoning incidents in the corresponding period.Standard species identification was carried out only in two poisonous mushroom incidents.Conclusions Mushroom poisoning incident was one of the most important causes of death in per-oral poisoning incidents.It should to cope with surveillance and meticulous management during high prevalence season and in high-risk provinces.At the same time,it should be strengthened to train doctors and health professionals with the knowledge of identification of mushroom poisoning in key areas as well as to develop the health promotion of mushrooms poisoning prevention.

Objective To detect the effects of bifidobacterium or bifidobacterium cultured supernatant on the mRNA expression of tumor necrosis factor receptor-associated factor 6 (TRAF6),glycogen synthase kinase-3β (GSK-3β) and the miRNA-146a in rat small intestinal epithelial cell(IEC-6) induced by lipopolysaccharide (LPS).Methods IEC-6 in logarithmic phase were randomly divided into LPS group,cultured supernatant group and inactivated bacteria group.All the 3 groups were exposed to 5 mg/L LPS for 5 hours,and then 1 mL sterile saline was added in LPS group and culturing continued for 24 hours ; 1 mL bifidobacterium cultured supernatant was added in cultured supernatant group and culturing continued for 24 hours;1 mL inactivated bifidobacterium 1 x 1010 CFU/L added in inactivated bacteria group and continued culturing for 24 hours.The mRNA expressions of TRAF6,GSK-3 β and miRNA-146a were detected by reverse transcription-polymerase chain reaction (RT-PCR).Results The level of TRAF6,GSK-3 β of culture supematant group (0.72 ± 0.05,0.46 ± 0.14) were all lower than LPS group (1.01 ± 0.14,1.02 ± 0.25),but the level of miRNA-146a(3.05 ± 0.40) was higher than that in LPS group(1.01 ± 0.12),and there were significant differences between them (t =5.278,6.316,13.218,P =0.000).The level of GSK-3 β of inactivated bacteria group(0.59 ±0.13) was significantly lower than that in LPS group(t =4.837,P =0.000).The levels of TRAF6 and miRNA-146a of inactivated bacteria group(1.05 ±0.11,0.78 ±0.22) had no significant differences with LPS group (t =0.732,1.463,P ＞ 0.05).The level of TRAF6 of cultured supernatant group was lower than that in inactivated bacteria group,and the level of miRNA-146a was higher than that in inactivated bacteria group,and there were significant differences between 2 groups (t =6.009,14.687,P =0.000).Conclusions Bifidobacterium cultured supernatant and inactivated bacteria both have certain protective effect on the IEC-6 induced by LPS.One of the protective mechanisms of bifidobacterium cultured supernatant may be achieved by elevating the expression of miRNA-146a,and decreasing the levels of inflammation related factor TRAF6 and damage related factor GSK-3β.The protective effects of inactivated bifidobacterium may be achieved by decreasing the level of damage related factor GSK-3β.

Objective To evaluate the feasibility and efficacy of catheter-directed thrombolysis (CDT) for the treatment of non-acute (history ＞ 14 days) deep venous thrombosis (DVT) of the lower extremity.Methods Clinical data of 63 patients of non-acute DVT of lower extremities treated by CDT and adjunctive angioplasty and stenting from July 2009 to August 2013 were analyzed retrospectively.Venous recanalization was graded by a thrombus score based on pre-and post-treatment venography.Follow-up was performed by Doppler ultrasound and clinical evaluation.Results A total of 63 limbs with DVT with a mean symptom duration of (22 ± 5) days were treated by a continuous combined with pulse-spray infusion of urokinase of (1.21 ± 0.69) million IU/d for (74 ± 21) hours.Significant recanalization was achieved in 77％ (48 of 63) of the treated limbs.After thrombolysis,percutaneous angioplasty was done for 15 residual lesions and stent placement was performed in 11 iliac veins and 1 femoral vein.Minor bleeding occurred in 6 (10％) patients,no patients suffered from major bleeding or symptomatic pulmonary embolism.During follow up (mean:15 ±6 months),the veins were patent in 45 (71％) limbs.15 (24％) limbs developed mild post-thrombotic syndrome (PTS),and none had severe PTS.Conclusions CDT combined with adjunctive angioplasty and stenting is safe and effective for removal of the clot burden and for restoration of the venous flow in patients with non-acute lower extremity DVT.

Objective To evaluate the feasibility and application of histopathology diagnosis of endometrial tissues obtained by endometrial cell collector (Jingyou, SAP-1). Methods One hundred and ninety-three patients whose endometrial lesions should be excluded were selected. First, endometrial tissue were obtained from the patients by Jingyou, then they underwent comprehensive curettage under hysteroscopy. The histopathology diagnosis was performed respectively. The specimen satisfaction rate and diagnostic accuracy was analyzed and compared. Results The specimen satisfaction rate of curettage under hysteroscopy was 95.85%(185/193). The specimens of 8 cases were not satisfied because the tissues were not enough. The specimen satisfaction rate of Jingyou was 82.38% (159/193). The specimens of 34 cases were not satisfied, among whom in 10 cases scratches did not throughout the whole palace antrum, and in 24 cases tissues quality were poor. The endometrial thickness in unsatisfactory specimen by Jinyou was significantly thinner than that in satisfactory specimen:(0.64 ± 0.18) cm vs. (0.97 ± 0.43) cm, and there was statistical difference (P<0.05). The diagnostic accordance rate between Jingyou and curettage under hysteroscopy was 79.87%(127/159). The sensitivity of Jingyou from high to low was 94.19% (81/86) in normal menstrual endometrial, 7/10 in endometrial carcinoma/ atypical hyperplasia, 67.86%(38/56) in endometrial hyperplasia and 1/7 in endometrial polyps. Missed diagnosis of jingyou inluded 2 cases of endometrial carcinoma and 4 cases of endometrial atypical hyperplasia. The misdiagnosed rate of high grade endometrial lesions was 6/16, and the patients were misdiagnosed because the tissues were not enough. Four cases of endometrial atypical hyperplasia had underwent conservative treatment of repeated curettage. Conclusions Application of Jingyou can obtain micro endometrial tissues, and the accordance rate of histopathology diagnosis is high with curettage under hysteroscopy. When the collector makes a comprehensive collection to the uterine cavity specimen, it can accurately screen endometrial carcinoma and atypical hyperplasia. The patients who have endometrial atypical hyperplasia and receive conservative treatment and curettage repeatedly curettage, thin endometrium and ultrasonic highly suspected endometrial polyps, are not recommend to use Jingyou to obtain specimen. When the specimen is not satisfied using the collector, additional hysteroscopy should be performed to avoid misdiagnosis of high grade endometrial lesions.
