Background T helper cell 17 (Th17),a newly discovered subset of CD4+ T cells,have been found to play an important role in dry eye disease in animal model.Further investigation should be done on the immunopathogenesis of Th17 cells in dry eye patients.Objective This study was to analyze the expression status of interleukin-17 (IL-17) and IL-22 in tear and supernatant of peripheral blood mononuclear cells (PBMCs) of dry eye patients and their correlation with clinical symptom and sign.Methods Twenty Sj(o)gren syndrome (SS)patients,twenty non-Sj(o)gren syndrome (NSS) patients were included in Wuxi Second Hospital from 2010 to 2011,and twenty healthy volunteers were recruited at the same period.All of subjects understood the purpose and procedure of research and written informed consent was obtained form each subject initial of this study.Dry eye symptom questionnairs were self-answered and multiple dry eye disease-related clinical tests,including the breakup time of tear film (BUT),Schirmer Ⅰ test (S Ⅰ t) and corneal fluorescein staining were performed.The periphery blood of 3 ml and tear were collected in all the subjects,and IL-17 and IL-22 levels in supernatant of PBMCs and tear were detected by enzyme-linked immunosorbent assay (ELISA).The correlations between levels of IL-17 and IL-22 with BUT,S Ⅰ t,corneal fluorescein staining and dry eye scores were analyzed.Results The dry eye scores reduced,BUT prolonged,S Ⅰ t increased and corneal fluorescein dye decreased from SS group,NSS group to normal control group,with significant differences among the three groups (dry eye scores:H =40.81,P＜0.01 ; BUT:H =40.15,P＜0.01 ;S Ⅰ t..H=50.07,P＜0.01 ;corneal dye scores:H=40.52,P＜0.01).The concentration of IL-17 in the supernatant of PBMCs in the SS patients,NSS patients and normal controls were (964.92±124.83)ng/L,(718.85± 115.89)ng/L and (341.95±85.08) ng/L,showing a statistically significant difference among them (F=162.95,P＜0.01).The levels of IL-17 in the tear were (440.69±126.09) ng/L,(364.33±126.85) ng/L and (61.16±11.60) ng/L in the SS group,NSS group and normal control group respectively,exhibiting an elevated level in the SS group and NSS group compared with the control group (F=75.27,P＜0.01).In addition,the levels of IL-22 in the supernatant of PBMCs in the SS patients,NSS patients and normal controls were (98.77± 11.27) ng/L,(79.65 ± 11.01) ng/L and (32.78±9.34) ng/L,and those in the tear were (22.22 ± 8.96) ng/L,(14.92 ±4.35) ng/L and (10.47 ± 2.67) ng/L,with significant differences among the three groups (F =206.27,P＜0.01 ;F =19.87,P＜0.01).The significant correlations were found between the IL-17 and IL-22 concentration in the supernatant of PBMCs and tear with corneal fluorescein staining scores and S Ⅰ t.Conclusions The contents of IL-17 and IL-22 in PBMCs and tear upregulate in the SS and NSS patients,indicating that Th17 plays a key role in the immunity mechanism of dry eye.

Objective To evaluate the value of differential diagnosis on congenital biliary atresia(BA) and infantile hepatitis syndrome(IHS) by technetium-99m-diethyl-iminodiacetic acid(99Tcm-EHIDA)hepatobiliary scintigraphy with phenobarbitol sodium.Methods Fifty-eight infants with persistent jaundice were taken phenobarbitol sodium[5 mg/(kg?d)] ,bid ?7 d).Those who had not bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of BA.Those with bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of IHS,who then received 99Tcm-EHIDA hepatobiliary scintigraphy with single photon emission computed tomography(SPECT) instrument.The results of all children were analyzed and compared with pathology and clinical follow up results.Results 99Tcm-EHIDA hepatobiliary scintigraphy correctly diagnosed 24 infants with last diagnosis BA and 29 infants with last diagnosis IHS,5 neonates false positive in all 34 IHS patients.The sensitivity in the diagnosis of BA was 100%,the specificity and accuracy were 85.3% and 91.4%,restectively.The sensitivity was 85.3% in the diagnosis of IHS;the specificity and accuracy were 100% and 91.4%,respectively.Conclusions 99Tcm-EHIDA hepatobiliary scintigraphy with phenobarbitol sodium can accurately differentiate BA and HIS at early stage.

OBJECTIVETo investigate the relation of heparanase gene and angiogenesis with the progress of gastric carcinoma (GC).

METHODSExpression of heparanase mRNA in 52 GC tissue was detected by in situ hybridization assay. Microvessel density (MVD) was examined by immunohistochemical method. MVD and heparanase mRNA expression were analysed with their relation to histological grade, invasion depth,lymph node metastasis and organ metastasis.

RESULTSMVD was 73.2 +/- 22.8 in 25 (48.1%) tissue with positive heparanase mRNA. It was 44.8 +/- 11.9 in 27 (51.9%) tissues with negative heparanase mRNA, between which the difference was significant (P < 0.001). MVD and heparanase mRNA expression were related with lymph node metastasis and depth of serosal invasion in GC (P < 0.005).

CONCLUSIONHeparanase, being related to angiogenesis in gastric cancer, promotes growth, invasion and metastasis. Heparanase mRNA expression is an important predictor of the biological behavior of human gastric carcinoma.

Objective To observe the protective effect of hydroxysafflor yellow A(HSYA) on anoxia/reoxygenation (A/R) injury of neonatal primary cardiomyocytes, and its relationship with phosphoinositide 3-kinase/protein ki-nase B/glycogen synthase kinase 3β(PI3K/Akt/GSK3β) signaling pathway. Methods Primary cardiomyocytes of neonatal rats were isolated from the rats and incubated for 48 hours. The cells were adhered to each other and then divided into five groups:control group (Con group), anoxia/reoxygenation group (A/R group),HSYA treatment group(A/R+H group),PI3K inhibitor (LY294002)treatment group(A/R+L group)and HSYA+LY294002 treat-ment group (A/R+H+L group),then to collect the supernatant fluid of each group to measure LDH.The flow cy-tometry was used to measure the apoptotic cells. The protein levels of Bcl-2,Bax,Akt,p-Akt (Ser473),GSK3β, p-GSK3β (Ser9) were evalated by Western blot. Results A/R increased LDH release,the apoptosis rate (P<0.001),and the expression of pro-apoptotic protein Bax (P <0.001) with the decrease of anti-apoptotic protein Bcl-2,p-Akt(Ser473), p-GSK3β(Ser9)(P<0.001) as compared with the control group. HSYA treatment de-creased LDH release,the apoptosis rate (P<0.001),and the expression of Bax (P<0.001) and increase the ex-pression of Bcl-2,p-Akt(Ser473),p-GSK3β(Ser9)(P<0.001). Compared with the A/R+H group,the expres-sion of Bax was increased (P<0.001),while the expression of Bcl-2, p-Akt(Ser473), p-GSK3β(Ser9)was de-creased (P<0.001) in the A/R+H+L group. Conclusions HSYA protects rats'cardiomyocytes from anoxia/reoxy-genation injury by regulating PI3K/Akt/GSK3β signaling pathway.

Background Mechanism of dry eye disease has not been established clearly.Some increasing evidences showed that inflammation plays an important role in pathogenesis and development of dry eye disease.However,the association of interleukin-6 (IL-6) with dry eye has not been clarified.Objective This study was to assess the correlation of IL-6 levels in tear and serum of patient with dry eye disease and clinical symptom.Methods Twenty patients with Sj（o）gren syndrome (SS) and 20 cases with non-Sj（o）gren syndrome (NSS) were enrolled from Second Affiliated Hospital of Nanjing Medical University,and 20 healthy volunteers were recruited as the normal controls.Symptom questionnaires were self-answered and multiple dry eye-related clinical tests were performed,including tear film breakup time (BUT),Schirmer Ⅰ test (S Ⅰ t) and corneal fluorescence staining.IL-6 concentrations in serum and tear were detected by enzyme-linked immunosorbent assay (ELASA).The correlation between IL-6 level and tear film and ocular surface parameters was analyzed by Spearman rank correlation.Written informed consent was obtained from each subject initial of this trial.Results The scores of symptom questionnaires were 18.50 (11.75,23.00),23.00 (19.00,32.00) and 2.00 (0.25,4.00) in the SS group,NSS group and the normal control group,and significantly increasing values were seen in the SS group and NSS group compared with the normal control group (P=0.00,0.00).BUT values in the SS group and NSS group were 2.50 (2.00,3.88) seconds and 3.50 (2.13,4.00) seconds and were lower than 15.00 (13.13,17.00) seconds in the normal control group (P=0.00,0.00).S Ⅰ t values in the SS group,NSS group and the normal control group were 2.00 (1.50,2.88),4.00 (3.00,5.75) and 19.00 (18.00,25.00)mm,showing significant differences between the SS group and the normal control group (P =0.00),the SS group and the NSS group (P =0.00) or the NSS group and the normal control group (P=0.00).The marked elevation of keratoepithelioplasty score was seen between the SS group and the normal control group (5.75 (4.00,7.75) vs.0.00 (0.00,0.75) (P =0.00) or the NSS group and the normal control group (4.50(3.63,6.00) vs.0.00(0.00,0.75)) (P=0.00).Concentrations of IL-6 in serum and tear in the SS group,NSS group were (131.47±21.04) μg/L and (77.81 ± 15.68) μg/L and were significantly higher than (31.62±8.57) μg/L of the normal control group,and those in the tear were (33.44±8.01) μg/L,(18.78 ±5.73) μg/L and (8.77 ± 3.43)μg/L,respectively in the three groups,with a significant reduce in the normal control group (all P=0.00).tL-6 levels in serum and tear were positively correlated with the score of symptom questionnaires or keratoepithelioplasty and negatively correlated with BUT and S Ⅰ t (all P =0.00).Conclusions IL-6 levels in the tear and serum of the dry eye patient are associated with the severity of the disease.IL-6 levels in serum and tear may be objective,sensitive and reliable indicators of dry eye.

Tetramethylpyrazine (TMP), an effective component of traditional Chinese medicine Chuanxiong, is commonly used to resolve embolism. Its possible therapeutic effect against atherosclerosis has received considerable attention recently. Angiotensin II (Ang II) is highly implicated in the proliferation of vascular smooth muscle cells (VSMCs), resulting in atherosclerosis. The mechanisms of TMP in the proliferation of VSMCs induced by Ang II remain to be defined. The present study was aimed to study the effect of TMP on Ang II-induced VSMC proliferation through detection of nuclear factor-kappaB (NF-kappaB) activity and bone morphogenetic protein-2 (BMP-2) expression. Primary cultured rat aortic smooth muscle cells were divided into the control group, Ang II group, Ang II + TMP group and TMP group. Cells in each group were harvested at different time points (15, 30 and 60 min for detection of NF-kappaB activity; 6, 12 and 24 h for measurement of BMP-2 expression). NF-kappaB activation was identified as nuclear staining by immunohistochemistry. BMP-2 expression was observed through Western blot, immunohistochemistry and in situ hybridization. The results showed that: (1) Ang II stimulated the activation of NF-kappaB. Translocation of NF-kappaB p65 subunit from cytoplasm to nucleus appeared as early as 15 min, peaked at 30 min (P<0.01) and declined after 1 h. (2) TMP inhibited Ang II-induced NF-kappaB activation (P<0.01). (3) Ang II increased BMP-2 expression at 6 h but declined it significantly at 12 and 24 h (P<0.01). (4) BMP-2 expression was also kept at high level at 6 h in Ang II + TMP group but maintained at the normal level at 12 and 24 h. (5) There was no significant difference in NF-kappaB activation and BMP-2 expression between the control group and TMP group. These results indicate that TMP inhibits Ang II-induced VSMC proliferation through repression of NF-kappaB activation and BMP-2 reduction, and BMP-2 expression is independent of the NF-kappaB pathway. In conclusion, TMP has therapeutic potential for the treatment of atherosclerosis.

OBJECTIVETo investigate the effects of transforming growth factor beta (TGF ) on c-fos gene expression in hepatic stellate cells.

METHODSHepatic stellate cells (HSC-T6) were cultured in the medium containing different concentrations of TGF (0.2, 1, and 5 ng/ml), and cells were collected at different time points of incubation (8, 24, 48, and 72 h). The total RNA of the HSCs was isolated and c-fos gene expression level were measured by reverse transcription polymerase chain reaction.

RESULTSc-fos gene expression levels of HSCs cultured in the presence of low (0.2 ng/ml), moderate (1 ng/ml) and high (5 ng/ml) concentrations of TGF for 8, 24, 48 and 72 h were significantly greater than those of control group. The c-fos gene expression levels of HSCs increased gradually with the increment of TGF concentration, and significant differences in c-fos gene expression were found between the 3TGF groups.

CONCLUSIONTGF strongly up-regulates c-fos gene expression in hepatic stellate cells.

OBJECTIVETo initially observe the effect of classical endotracheal intubation on endotracheal bacterial contamination and evaluate the validity of protective endotracheal intubation on reducing endotracheal bacterial contamination.

METHODSNinety elective patients undergoing general anesthesia for hysterectomy were randomly assigned to two equal groups. Group II received endotracheal intubation protected by sterilized transparent sleeve while group I correspondingly adopted unprotective classical endotracheal intubation. Endotracheal swab sampling and bacterial counting were performed on the principle of aseptic processing before endotracheal intubation and extubation, respectively.

RESULTSBacteria were found in 62 of 180 samples. The difference of bacterial counting between before extubation and before intubation was (-0.3 +/- 35.6) 100 CFU/ ml in group II, lower than that in group I, which was (21.4 +/- 56.7) 100 CFU/ml (P<0.05).

CONCLUSIONEndotracheal bacterial contamination may be caused by unprotective classical endotracheal intubation and could be reduced by protective endotracheal intubation.
