Objective Previous researches demonstrated that pyrroledithiocarbomate (PDTC), an inhibitor of nuclear factor, results in specific inhibition on nuclear factor-κB and therefore suppress cataract formation. The aim of this study was to explore the effect of nuclear factor-κB inhibitor on cataract formation after alkali burn in rats. Methods Ocular surface alkali burn models were established in the right eyes of 40 SPF Wistar rats by putting the 7 mm filter paper with 1 mol/L NaOH in the central cornea for 60 seconds. PDTC (2 mg/mL, 0. 1 mL) was subconjunctivaly injected everyday in 20 model eyes and the equivalent amount of normal saline solution was used in the same way in other 20 model eyes. The rats were killed in the first, third, fifth and seventh day after alkali burn and lenses were obtained for the histopathological examination, and immunochemistry and polymerase chain reaction were used to detect the expression of nuclear factor-κB in lens epithelial cells. The experiment and use of animal followed the Standard of Association for Research in Vision and Ophthalmology. Results After alkali burn, lens epithelial cells namely fell off in control group but those of experimental group were complete in the first day. In the third day, the lens cortex was obviously condensed in both two groups. In the fifth and seventh day, the lens epithelial cells fell off and lens cortex was obviously briquetted. Lots of vacuole and fragments could be seen in both groups. The gray scale value of nuclear factor-κB in lens epithelial cells were significantly higher in 1 day and 3 days after alkali burn in PDTC group compared with control group(t =2. 836, P =0. 036; t =4. 932, P =0.004) . The nuclear factor-κB /p-actin values were considerably lowed in 1 day and 3 days after alkali burn in PDTC group compared with control group (t = 31. 563, P = 0. 000; t = 17. 837, P = 0. 000). No statistically significant difference were found in gray scale values of nuclear factor-κB and nuclear factor-κB/p-actin values in 5 days and 7 days after alkali burn between PDTC group and control group (P＞0. 05). Conclusion Early usage of inhibitor of nuclear factor plays a suppressive role in cataract formation after ocular surface alkali burn of rat model.

Objective That decline of estradiol in serum of postmenopausal women can result in dry eye has been accepted at present. However, the change of estradiol in tear of postmenopausal women has been not reported ever. This study was to discuss the relationship between dry eye syndrome and estradiol in tears and serum of postmenopausal women. Methods Total 62 eyes of 62 women were collected in this trial. The aim of this trial was informed orally and the informed consent was obtained from all the subjects. The 32 right eyes were from menopausal women for more one year and 30 right eyes were from premenopause women. The dry eye was diagnosed based on the abnormalities of tear break-up time (BUT), Schirmer I test, corneal fluorescence and subjective symptom of patients. The periphery blood specimen was collected from all the subjects, and tear specimen was obtained and quantified using filter paper. Estradiol contents in tears and serum were determined by chemiluminescence method. The bulbar conjunctiva was obtained by impression cytology, and the microstructure of conjunctiva was observed under the scanning electron microscopy. Results In comparison to the premenopause group, the content of estradiol in tears and serum in menopause group was significantly reduced(73. 50 ±24.47 vs 17. 43 ± 10. 92) (U = -6. 396, P =0. 001). In the premenopause group, the estradiol content between tear and serum showed the positive correlation (r = 0. 838, P = 0. 001) . However, no statistical correlation was found in estradiol content between tears and serum in menopause group(r =0. 127, P = 0. 487). The maicrostructure changes were seen in the dry eyes of postmenopausal women, and decrease of goblet cell and loosen of intercellular junction were found under the electron microscope. Conclusion The content of estradiol in tears in menopause group is significantly lower than that in the premenopause group. Estradiol content in tears and serum of the postmenopausal women showes insignificant correlation. This result indicates that the topical substitute therapy with estradiol is possible in dry eye.

Objective To improve the diagnosis of tuberculosis ( TB) by analyzing Mycobacterium infection in fine-needle aspiration biopsy specimens from children with tuberculous lymphadenitis .Methods Fine-needle aspiration biopsy was performed on 269 children with tuberculous lymphadenitis diagnosed by Shanghai Public Health Clinical Center from January 2011 to September 2013 .The needle aspiration biopsy specimens were processed for acid-fast bacillus (AFB) smear test, mycobacterial culture and Mycobacterium identification ( p-nitrobenzoic acid inhibition test ) .Results Cytological diagnosis of tuberculous lymphade-nitis was made for 269 patients.The positive results by AFB smear test were detected in 63.19% of 269 specimens (n=170) and 40.15%(n=108) specimens were positive in mycobacterial culture .The differ-ence between the two tests were significant (P<0.01).The positive rate of Mycobacterium detected by using BACTEC MGIT 960 automated system and L?wenstein-Jensen culture method were 38 .66% ( n=104 ) and 28.99%(n=78), respectively, showing the significant difference between two tests (P<0.05).AFB smear test in combination with mycobacterial culture could precisely diagnose 70.63% of tuberculous lym-phadenitis in children.Of the 108 clinical isolates, 105 strains (97.2%) were Mycobacterium tuberculosis complex and the rest were non-tuberculous Mycobacterium strains (2.8%).Conclusion The positive rate by AFB smear test was significantly increased in fine needle aspiration biopsy specimens after a series of treatments including sample digestion , centrifugation and precipitation , but the positive rate of mycobacterial culture was reduced .Diagnostic accuracy could be significantly improved by using BACTEC MGIT 960 sys-tem.Mycobacterium tuberculosis complex was the predominant pathogenic bacterium in children with tubercu-lous lymphadenitis .

Background:The incidence of ulcerative colitis (UC)in developed countries is higher than that in developing countries,which may be related with westernized lifestyle,especially high animal protein and low complex carbohydrate diet. With the increased high fat and meat intake,synthesis and secretion of bile acid in liver is also increased,which may have an impact on the occurrence of UC. Aims:To investigate the expressions of farnesoid X receptor (FXR)and G protein-coupled bile acid receptor 5 (TGR5)in patients with UC. Methods:Thirty patients with active UC from January 2013 to June 2016 at the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled,and 30 healthy subjects were served as controls. Expressions of FXR and TGR5 were determined by immunohistochemistry. Results:Compared with control group,expression of FXR was significantly decreased in UC patients (4. 63 ± 2. 07 vs. 6. 91 ± 2. 62,P =0. 00),however,no significant difference in expression of TGR5 was found between the two groups (6. 70 ± 2. 90 vs. 6. 11 ± 2. 44,P = 0. 40). Expression of FXR was significantly increased in right hemicolon colitis than in left hemicolon colitis (P < 0. 05). Conclusions:There is a significant decrease in FXR in active UC patients,indicating that FXR may have some role in the pathogenesis of UC,however,TGR5 may have no obvious effect in the pathogenesis of UC.

Objective To study the mutations of outer-membrane porin gerte (oprD) in imipenem-resistant Pseudomonas aeruginosa.Methods The PCR was applied to detect the oprD gene from the 34 clinical imipenem-resistant Pseudomonas aeruginosa.DNA sequence was proceeded to analysis the nuclentide sequence of the oprD gene and the deduced amino acid sequence.To analysis the mutation and the function of the oprD domain,those mutations were compaired with the standard Pseudomonas aeruginosa ATCC27853 and 2 clinical imipenem-susceptibility isolates.Results oprD gene mutation was wide and diverse.The rate of the mutation was 92.3% (12/13),mutations were concluded dot mutation,deletion mutation and insert mutation,those result in the amino sequence change and frame shift in L2 and L3 loops of outer membrane protein D,hampering the combine of oprD and imipenem.Some new mutations were found.They were 1 079,1 114,1 196,1 206,1 288,1 300,1 301 bases and 115,127,154,158,185,189 aminos.All above mutations were not deteced in ATCC 27853 and 2 clinical imipenem-susoeptibility isolates.Conclusions The wide and diverse mutations in oprD gene result in amino acid change and/or frame shift L2 and L3 loops,hampering the binding of IMP and oprD.Those may result in resistance to imipenem in Pseudomonas aeruginosa.
