AIM: To observe the efficacy and safety of intravitreal injection of Conbercept for the treatment of wet age-related macular degeneration( AMD) .
METHODS:Retrospective analysis. A total of 20 patients involving 22 eyes were diagnosed of wet AMD and confirmed by routine ophthalmic examination, fundus fluorescein angiography ( FFA ) and optical coherence tomography. All these affected eyes received intravitreal injection of 10 mg/ml of 0. 5mg Conbercept, once monthly, for 3 successive times during the initial treatment. The need for repeated treatment was determined according to patients'disease conditions. The patients were followed up once monthly for ≥6mo. The changes in best corrected visual acuity ( BCVA ) , central retinal thickness ( CRT ) and choroidal neovascularization ( CNV) lesion leakage of the affected eyes before and after treatment were compared and analyzed.
RESULTS:Within 1, 3 and 6mo after treatment, the mean BCVA ( logMAR ) of the affected eyes increased when compared with before treatment;the difference was statistically significant(P<0. 01). In 1, 3 and 6mo after treatment, the mean CRT of the affected eyes decreased when compared with before treatment;the difference was statistically significant(P<0. 01). During the last follow-up, FFA showed that macular CNV lesion leakage disappeared in 20 eyes(90%) while leakage mitigated in 2 eyes ( 9%) . During the follow - up, there were no treatment - related serious ocular complications and systemic serious adverse reactions.
CONCLUSION: Clinically, intravitreal injection of Conbercept for the treatment of wet AMD can increase visual acuity of the affected eyes. It also can decrease CRT of the affected eyes, and inhibit neovascular leakage. There are no treatment-related adverse reactions.

Objective To compare the yield and speed of detection of Salmonella subsp, enterica serotypo Paratyphi A from the blood of patients with suspected paratyphoid fever A. Methods With the BacT/ALERT 3D system and paired aerobic and anaerobic bottles (AEB, ANB) that were each filled with 5 ml of blood, the blood culture of 13 500 suspected paratyphoid fever A patients were performed. Results A total of 4 060 isolates were detected. About 3 149 were detected from both AEB and ANB. Four hundred and sixty-one isolates were detected only from the AEB and 450 were only from the ANB. The detection rates of the AEB and ANB were all 26.7% (χ<'2>=0.023, P=0.880). The increased detection rate attributed to the additional blood volume in the AEB and ANB were 11.3% and 11.1%, respectively. The detection speed differed between the two medium formulations. The time to detection was (23.66±15.89) h and (25.48±16.92) h for3 149 isolates, respectively (t=7.007, P<0.01).The mean time to detection was 31.80±20. 97 for 461 isolates discovered with AEB and (33.45±20.72) h for 450 isolates discovered with ANB. Conclusion The blood volume is an important factor in determining the detection rate of blood culture. Although no statistical difference for positive rate was found between the AEB and ANB, more isolates was detected earlier in AEB.

Objective To probe the changes of CT values in liver parenchyma in order to evaluate the therapeutic effect of acute pancreatitis.Methods 104 patients with acute pancreatitis which were diagnosed and treated by department of gastroenterology.Ac-cording to pathological results,the patients were divided into mild acute pancreatitis (MAP)group and severe acute pancreatitis (SAP)one.The CT values of liver parenchyma were measured before and after treatment,and the correlations between CT values changes and the amylase in blood and urine were analyzed.Results The CT values of liver parenchyma showed a negative correlation with the pathological severity of acute pancreatitis (r=-0.089,P <0.05).The accuracy using the changes of CT values to evaluate the therapeutic effect was significantly different between the MAP and the SAP group with different sensitivity of 92.2% and 85.7%and specificity of 33.3% and 94.1% respectively.In addition,the changed trend of CT values in liver parenchyma showed negative correlations with triglycerides and blood amylase.Conclusion CT scan is a useful imaging method in evaluating the liver damage and the therapeutic effect in patients with acute pancreatitis in emergency.

Purpose To explore the immunohistochemical features of neuroendocrine markers, CKpan and TTF-1 and their relationship to TNM stage and prognosis in small cell lung cancer (SCLC). Methods The expression of NSE, CgA, Syn, CD56, TTF-1 and CK-pan in SCLC tissue specimens were detected using immunohistochemical EnVision indirect method. Clinical data and TNM stage of 90 patients were collected and the overall survival ( OS) was followed up by telephone. Results Of 90 cases of SCLC, the vast majority were occured in the elderly men. The ratio of man to woman was 5 to 1. The median age was 64 years old. The stageⅠ+Ⅱ was 21 cases, 30 in stageⅢand 39 cases in stage IV. The positive rate of immunohistochemical staining of neuroendocrine markers for NSE, CgA, Syn and CD56 were 83. 3%, 70%, 65. 5% and 86%, respectively. The positive rate of CKpan, TTF-1 were 92. 2% and 81. 1%. Kaplan-Meier analysis indicated that the expression of TTF-1 and NSE were significantly correlated with the TNM stage and over-all survival of patients with SCLC (P<0. 05). The median OS was 8 months in positive expression of TTF-1, which was higher than those in negative expression of TTF1 (5. 5 months)(P=0. 000). The median OS was 7 months in NSE positive expression which was lower than those in negative expression of NSE (11 months)(P=0. 009). The median OS of stageⅠ+Ⅱ,ⅢandⅣwere 16 months, 9 months and 4 months with significant difference ( P=0. 000 ) . Cox multivariate analysis indicated the TTF-1 expression and TNM were independent prognostic factors for the OS of the SCLC patients. Conclusion Most of SCLC has neuroendocrine differentiation, expression CKpan and TTF-1. The expression of TTF-1 may be negative correlation but NSE positive correlation with the prognosis of SCLC patients. And the TTF-1 expression and TNM may be independent prognostic factors for the OS of the SCLC patients.
