Purpose:To study clinical and pathological features of solid-pseudopapillary tumor(SPT) of the pancreas. Methods:The clinical data were reviewed in four patients with SPT. Immunohistochemistry for Vim, CK8, CK18, Chromogranin, Sy, AAT, NSE, S-100 was performed in all four cases using EnVision. Results:All four patients were female. The mean age was 30 years. The tumors were composed of papillary and solid structures. The uniform cells were strongly diffuse positive for Vim, and strongly positive for focal AAT in four cases. Three cases were positive for NSE. All four cases were negative for Sy , Chromogranin and S-100. One case was poorly positive for CK8 and CK18. Conclusions:SPT of the pancreas, preferentially in young women, is a tumor with low malignant potential. Immunohistochemistry is very important in the diagnosis and differential diagnosis of SPT of the pancreas..

Objective:To investigate the correlation between plasma homocysteine (Hcy) concentration and transient ischemic attack (TIA) and traditional vascular risk factors.Methods:The plasma Hcy concentrations of 112 patients with TIA and 62 controls were measured by fluorescenee polarization immunoassay.Hcy concentrations and related risk factors were analyzed.Results:The risk of TIA was increased significantly in plasma Hcy concentration 10.0 to 14.9 μmol/L group(OR=2.450,95% CI 1.091 to 5.502) and≥15.0 μmol/L group(OR=5.169,95% CI 2.096 to 12.746) compared with plasma Hcy concentration＜10.0 μmol/L group.Using TIA as the dependent wariable,various vascular risk factors (including plasma Hcy concentration) as the independent variable,logistic regression was analyzed.The result showed that the risk of TIA was increased significantly in plasma Hcy concentration＞10.0 μmol/L group compared with plasma Hcy concentration＜10.0 μmol/L group(OR=3.150,95% CI 1.380 to 7.192).Conclusions:Plasma Hcy concentration is an independent risk factor for TIA.

OBJECTIVETo study the clinical effect of acupoint stimulating control (ASC) in treating obsessive compulsive neurosis.

METHODSThe comparative study was conducted in 65 patients with obsessive compulsive neurosis, they were divided into two groups, the 33 patients in the control group treated with chlorimipramine and the 32 in the tested group treated with ASC. The therapeutic efficacy and adverse reaction were assessed according to the standard for clinical efficacy evaluation by Yale-Brown scale for obsession (Y-BOCS)and adverse reaction scale.

RESULTSThe curative rate and markedly effective rate in the control group was 24.2% (8/33) and 27.3% (19/33), which in the tested group was 37.5% (12/32) and 34.4% (11/32) respectively. Significant difference was shown in comparison of Y-BOCS score between the two groups from the end of the 4th week of treatment (P < 0.05), indicating the efficacy in the tested group was better than that in the control group. Moreover, the occurrence of adverse reaction was higher in the control group than that in the tested group.

CONCLUSIONASC is a treatment with good effect, less adverse reaction and favourable safety superior to the treatment by chlorimipramine.

Objective: To analyze the influence of atmospheric particulate matters (PM_2.5 and PM₁₀) on low-birth-weight (LBW) infants at different periods of gestation. Methods: We conducted a systematic literature search for 2 471 articles related to particulate matter and LBW published from January 1st 2000 to January 1st 2016 using the PubMed, Cochrane Library, Web of Science, Science Direct, Chinese Web of Knowledge, Wanfang and Weipu, and the keywords were" air pollution" , "adverse birth outcomes" , "adverse pregnancy outcomes" , "low birth weight/LBW" . According to criteria, 27 literatures were selected and included. Metafor package of the R 3.1.1 Software was used to check the heterogeneity and merge the effect value of the selected literatures, and sensitivity analysis and publication bias were detected and adjusted. Results: A total of 2 471 studies selected form the databases, 27 enrolled in this analysis according to the inclusion and exclusion criteria. Each 10 μg/m³ increase in PM_2.5 was associated with combined OR values of 1st trimester, 2nd trimester, 3rd trimester and entire gestation at 1.02(95% CI: 0.87-1.19), 1.03 (95% CI: 0.91-1.16) , 1.07 (95%CI: 1.04-1.11) and 1.09 (95%CI: 1.04-1.15), respectively. And 10 μg/m³ increase in PM₁₀ was associated with combined OR values of 1st trimester, 2nd trimester, 3rd trimester and entire gestation at 1.66 (95%CI: 1.06-2.61), 1.58 (95%CI:1.28-1.95) , 1.38 (95%CI: 1.23-1.56) and 1.04 (95%CI: 0.99-1.09), respectively. After adjusting the bias of publication, each 10 μg/m³ increase in PM_2.5 was associated with the risk of low birth weight at 1.11 (95%CI: 1.02-1.21). Conclusion This meta analysis supports an adverse impact of maternal exposure to particulate air pollution on low birth weight, varying in effects by exposure period.

Objective To determine the association between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) and early neurological deterioration (END) in patients with acute ischemic stroke (AIS).Methods Two hundred and fifty-five AIS patients diagnosed by MR imaging were recruited between January 2011 and July 2015.The levels of serum Lp-PLA2 and high-sensitivity C-reactive protein (hs-CRP) were assessed right after hospitalization.END was defined as any increase in National Institutes of Health Stroke Scale (NIHSS) scores ≥ 2 in the first 72 h after stroke onset,and the patients were accordingly divided into END group and non-END group.Risk factors associated with END and their clinical data were analyzed by Logistic regression analysis.Results END was observed in 72 of the 255 patients (28.23％).The percentage of female (58.3％ vs.31.3％),smoking ratio (58.3％ vs.31.3％),diabetes mellitus ratio (73.6％ vs.16.9％),prior stroke ratio (44.4％ vs.25.1％),NHISS scores (8 [3] vs.3 [2]),serum Lp-PLA2 level (230.31 ±75.57 μg/L vs.87.60±28.45 μg/L) and hs-CRP level (20.08±8.05 mg/L vs.6.73±3.48 mg/L) in the END group were significantly higher than those in the non-END group (P＜0.05).Multiple Logistic regression analyses indicated that END was positively associated with diabetes mellitus (OR=4.903,95％CI:1.363-17.695,P=0.015),Lp-PLA2 level (OR=1.032,95％CI:1.013-1.043,P=0.000) and hs-CRP level (OR=1.229,95％CI:1.087-1.391,P=0.001) in patients with acute ischemic stroke.Conclusion Serum Lp-PLA2 may predict END in Chinese patients with acute ischemic stroke.
