AIM: To study the adverse reactions of hydroxychloroquine (HCQ) in ophthalmology. 　METHODS: Thirty-nine patients treated with HCQ for more than six months were performed ophthalmic examinations including some specifie retinal function tests. 　RESULTS: There were 3 patients (8%) who presented the visual fields was minified. The visual acuity of one patient was decreased. The cumulative doses of HCQ were more than 100 g in this three patients. 　CONCLUSION: The adverse reactions of HCQ in ophthalmology are related with the cumulative doses of HCQ. The expression is that the visual fields and visual acuity are decreased.

Objective To explore the protective effect of Ligustrazine on pulmonary fibrosis caused by hyperoxia in neonatal rats.Met-hods Eighty Sprague-Dawley(SD)clean neonatal rats,which were less than 12 hours old,were enrolled in this study.The neonatal rats were randomly divided into 4 groups:air-exposed control group(group A);air-exposed plus Ligustrazine-treated group(group B);hype-roxia-exposed control group(group C);hyperoxia-exposed plus Ligustrazine-treated group(group D).The neonatal rats of group B and group D were intraperitoneally injected with Ligustrazine[30 mg/(kg?d)] in solution of normal saline(NS),group A and group C were intraperitoneally given the same dose of NS.On 14th day,10 rats of each group were randomly chosen and then killed,the pulmonary pathological changes were observed by HE staining under light microscope.The area percentages of collagen fibers were measured by Masson staining and imaging analysis.The degree of pulmonary fibrosis was evaluated by the area percentages of collagen fibers and hydroxyproline content.The results were analyzed by SPSS 13.0 software.Results On the 14th day of the exposure,the histopathologic examination demonstrated broadened lung interstitium and reduced alveolar quantity and lung fibrosis were developed in group C;Ligustrazine treatment obviously alle-viated the changes of lung histomorphology.The newborn rats in group C had lower body weight compared that of with group A,B(Pa0.05).Conclusion Early use of Ligustrazine can decrease the severity of the pulmonary fibrosis of neonatal rats exposed to hyperoxia.

Objective To investigate the value of C- reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-?) in early diagnosis of neonatal sepsis. Methods Sixty- five newborns were divided into experiment group and control group, experiment group was also divided into sure group and doubtful group by blood culture We assessed the level of serum CRP, IL-6 and TNF-? in 24 hours and after 24 hours of clinical diagnosis of sepsis in experiment group, and examined the blood culture before antibiotic treatment Serum CRP, IL-6 and TNF-? were also examined in 3 to 6 days old. Results 1 The levels of serum CRP, IL-6 and TNF-? in experiment group were significantly higher than that in control group 2. The sensitivity of IL-6 and TNF-? were higher than CRP in 24 hours in experiment group. 3. After 24 hours, the sensitivity of CRP was elevated,and there was no statistical difference compared with the IL-6. Conclusion IL-6 and TNF-? are the credible marker in the early diagnosis of neonatal sepsis, and are more sensitive than the CRP, the IL-6 is the first sensitive marker.

Background and purpose:We have already reported viral macrophage inflammatory protein-Ⅱcan induce surface chemokine receptor CXCR4 internalizated.Based on the diverse biological functions of SDF-1?/ CXCR4,this study was to investigate the effect of SDF-1?on invasion and metastasis of human breast carcinoma MCF-7 cells.Methods:MCF-7 cell's ability of invasion,metastasis and anoikis were used as end points.The invasive ability was measured by the number of cells that were able to penetrate polycarbonates coated with matrigel.The metastastatic ability was analyzed by Transwell chamber.The anoikis ability was detected by FCM.Results:SDF- 1?+MCF-7 cells formed long and abundant pseudopodia,and only few filopodia were detectable in MCF-7 cells.It was shown that adhesive and metastasis capability of MCF-7 cells was enhanced with SDF-1?cocultured(P

Objective To evaluate the predictive value of diffusion weighted imaging ( DWI) for progres-sion free survival(PFS)in patients with cervix cancer after neoadjuvant chemotherapy (NACT).Methods Thirty two consecutive patients with pathologically confirmed cervical cancer underwent MRI including DWI before and after NACT.Pathologic results and MR images were reviewed .Univariate analysis was applied by Kaplan -Meier method.The Cox proportional hazard model was used to evaluate prognostic variables for multivariate analysis .Re-ceiver operating characteristic ( ROC) curves were used to find optimal cutoff values of independent prognostic fac -tors for disease progression.Results Of 32 patients,10 had disease progression during follow -up period.In uni-variate analysis,FIGO stage,tumor size,the depth of tumor invasion,lymph node metastasis and ADC changes be-tween before and after neoadjuvant chemotherapy (ΔADC) were significantly associated with the disease progres-sion.In multivariate analysis , FIGO stage and ΔADC were the independent prognostic factors for PFS .Optimal cutoff values that determined by ROC curves analyses were FIGO stage ⅡandΔADC 0.31.Area under the ROC curve(AUC)of FIGO stage and ΔADC were 0.841(sensitivity 90.0%,specificity 68.2%)and 0.864(sensitivity 80.0%,specificity 81.8%),respectively.Conclusion In patients with cervix cancer after NACT ,FIGO stage andΔADC are significant predictive values for PFS .

Objective To study the expression of Th1 and Th2 types cytokines in patients with esophageal squamous cell carcinoma and the clinical significance. Methods The expressions of Th1 ( INF-γ、IL-2) and Th2 (IL-4) types cytokines in cultured peripheral blood mononuclear cells (PBMC) from 30 healthy controls and 45 esophageal squamous cell carcinoma patients were determined by Enzyme-linked immunosorbent assay (ELISA). Results Compared with the control group, the expressions of Th1 type cytokines, IL-2 and INF-γwere significantly lower in the cultured PBMCs from the cancer patients (tINF-γ= 18. 24 ,tIL-2 = 15.31 ,Ps ＜0. 01 ) ,while the expression of Th2 type cytokines,IL-4 was significantly higher in the cultured PBMCs from the cancer patients ( tIL-4 = 5.79, P ＜ 0. 05 ). The expression changes of the cytokines showed a correlation with TNM (tumou-node-metastasis) stage of the tumor. Conclusion The Th1/Th2 shift existed in patients with esophageal squamous cell carcinoma and it might be one of the underline mechanisms of tumor immune escape.
