Objective To systematically review the relationship between mycoplasma infection and rheumatoid arthritis (RA).Methods Articles on case-control studies about the relation between mycoplasma infection and RA were collected by literature searching according to the selection criteria.Meta-analyses were performed for the included studies using RevMan 4.3.2 software.The odds ratio (OR) and its corresponding 95% confidence interval (95%CI) were calculated by Meta-analysis.Results Seventeen casecontrol studies involving 729 RA patients and 1191non-RA controls,such as osteoarthritis (OA),reactive arthritis (ReA),gouty arthritis (GA),healthy controls were included.The results of Meta-analyses showed that there was a significant difference in the infection ratio of mycoplasma between patients with RA and non-RA (OR=4.40,95%CI 2.26 to 8.56,P<0.01),and sensitivity analysis according to different published date and detection methods showed no difference.There were also significant differences between RA patients and OA patients (OR=11.29,95%CI 5.55 to 22.97,P<0.01) and healthy controls (OR=6.80,95%CI 3.96 to 11.67,P<0.01).Conclusion Mycoplasma infection is associated with RA.More evidence are needed to prove whether mycoplasma has played an equal role in RA and ReA,as well as the significant difference of mycoplasma infection between RA and GA groups.

AIM:To observe the image features of Vogt-Koyanagi-Harada disease (VKH) and multiple central serous chorioretinopathy (CSC) by fundus fluorescein angiography (FFA) and optical coherence tomography (OCT).METHODS:Thirty-two eyes of 17 patients with VKH and thirty-five eyes of 30 patients with multiple CSC were collected from 2009 to 2016 in my hospital.RESULTS:All the eyes with VKH were found small and dense fluorescein leakage in the early stage.The 17 eyes (53%) with VKH were found fluorescein accumulation in the final stage;24 eyes (75%) with VKH were found high fluorescence of optic disc.All of eyes with multiple CSC were found multifocal leakage in the early stage.And 2 eyes (6%) with multiple CSC were found high fluorescence of optic disc.There were 28 eyes (14 patients) with VKH and 25 eyes (22 patients) with multiple CSC had been done OCT in my hospital.Retinal pigment epithelial fold was only found in VKH.Fluctuation of internal limiting membrane (ILM) and membrane structure had higher sensitivity to diagnostic VKH from to multiple CSC, with sensitivity of 54% and 68% respectively.CONCLUSION:There are some similarities as well as differences between FFA and OCT in diagnosis of VKH and multiple CSC.A combination usage of FFA and OCT can be more effective in distinguishing VKH from multiple CSC.

Objective To evaluate the clinical efficacy of 5-aminolevulinic acid-induced photodynamic therapy (ALA-PDT) in the treatment of condyloma acuminatum. Methods Thirty-six cases of condyloma acuminatum were treated with ALA-PDT. Results After the treatment, 33 (91.67%) patients were cured, 35 (97.22%) improved. Relapse occurred in 3 (8.33%) patients. Side effects were noted in 2 (5.56%) patients. Conclusions ALA-PDT is a relatively simple, effective and safe treatment with a lower recurrence rate for condyloma acuminatum, especially for small skin lesions or lesions at specific area. However, the high expense required for multiple treatments with ALA-PDT may restrict its application.

Objective:To explore the application of speckle tracking imaging (STI) stratification strain technique in the assessment of circumferential myocardial function and the myocardial protection of ATP-postconditioning (ATP-PostC) in a rabbit model of acute myocardial infarction.Methods:A total of 40 rabbits were randomly divided into 2 groups: pure ischemia reperfusion group (IR group)and ATP-PostC group. STI images were recorded before and 45 min after occlusion of coronary artery, post low-dose dobutamine stress echocardiography, 60 and 120 min after reperfusion, respectively. The following parameters were obtained: left ventricular ejection fraction(LVEF), heart rate (HR), endocardial circumferential systolic strain (CSsys-endo), mid-myocardial circumferential systolic strain (CSsys-mid) and epicardial circumferential systolic strain (CSsys-epi) at left ventricular short-axis level. At different time points after occlusion and reperfusion, 5 experimental rabbits were killed in each group for pathological examination.Results:①Forty-five min after coronary artery occlusion in both groups, the values of LVEF and HR were decreased( P<0.05), and the absolute values of CSsys-endo, CSsys-mid and CSsys-epi were significantly reduced( P<0.01). After LDDSE, the absolute values of CSsys-endo, CSsys-mid and CSsys-epi were increased, which were different from those after blockade( P<0.05). ②After reperfusion, the circumferential strains were not significantly different from those after blockade in IR group ( P>0.05). After blockade, the absolute values of circumferential strains were increased significantly in the ATP-PostC group compared with IR group( P<0.05). In the ATP-PostC group, the absolute values of CSsys-endo at different time points after reperfusion increased significantly compared with that after blockade ( P<0.05). The absolute values of CSsys-endo and CSsys-mid 120 min after reperfusion continued to increase significantly compared with those 60 min after reperfusion( P<0.05). ③Pathological examination: After 60 min of blockade, there was no significant difference in myocardial infarction area between the IR group and the ATP-PostC group( P>0.05). The percentage of infarct areas at each time point of reperfusion in the ATP-PostC group was decreased compared with that after blockade( P<0.05). Compared with the IR group, the percentage of infarct area in the ATP-PostC group was smaller after 120 minutes of reperfusion and the difference was statistically significant ( P<0.05). Conclusions:The applications of STI stratification strain technique and LDDSE can assess left ventricular circumferential strains at each of myocardial layers before and after reperfusion in rabbit myocardial ischemia ATP-PostC model, identify and evaluate the function of viable myocardium, and exhibit the significant protective effects of ATP-PostC on myocardial reperfusion injury.

Objective To study the effect of different dose fractionation on overall survival in patients with limited-stage small cell lung cancer (LS-SCLC). Methods LS-SCLC patients treated with radical combined chemotherapy and radiotherapy (RT) between January 2001 and Dec 2007 were analyzed retrospectively. According to the dose fractionation schemes, patients were divided into three groups:conventional fractionated RT (1. 8 -2.0 Gy,once daily), hyperfractionated RT (1.4 Gy, twice daily) and hypofractionated RT (2. 5 Gy,once daily). Overall survival, disease free survival and pattern of failures of the three groups were compared. A total of 177 patients were enrolled, including 63 patients in conventional fractionated RT group, 79 in hyperfractionated RT group and 35 in hypofractionated RT group. Results The overall follow-up rate was 96. 6%. The patient numbers with follow-up of more than 2 and 5 years were 153 and 92, respectively. The median survival time of the entire group was 22. 4 months, and the 2-and 5-year survival rates were 43.4% and 23. 5%, respectively. The 2-year survival rates for three groups were 31%, 46% and 59% (x2 =7.94,P=0.019), respectively. The 2-year disease free survival for three groups were 20%, 31% and 40% ( x2 = 4. 86, P = 0. 088 ), respectively. In the pairwise comparisons,patients in hypofractionated RT group have better survival than those in conventional fractionated RT group ( x2 = 7. 81, P = 0. 005 ), the effect of hyperfractionated RT group lies between the hypo-and the conventional fractionated RT groups, but no significant differences were detected ( x2 = 2. 31, P = 0. 128; x2 = 2. 95, P =0. 086). The mildest side effect was found in the hypofractionated RT group. No statistically significant differences were found in the patterns of first failure. Conclusion The hypofractionated RT scheme showed potential survival benefits for patients with LS-SCLC and should be considered in the setting of randomized clinical trials.
