Objective To investigate the relevance between the times of cytokine-induced killer cell (CIK cell) adoptive immunotherapy and the survival of the elderly patients with gastric cancer.Methods Lymphocyte separation medium was used to isolate mononuclear cells, and then the cultured CIK cells were infused back into the patients with gastric cancer. A retrospective cohort study was adopted by using Kaplan-Meier to estimate median survival time and survival rate, using Log-rank test to analyze the impact of clinical factors on survival rate, and using RR and 95% CI to estimate the contact intensity of death outcome, survival time and CIK cell treatment. Results There were nostatistically significant differences in gender,age, tumor site, histological type, invasion depth, lymph node metastasis, pathological grade, tumor size or tumor distribution between chemotherapy group and CIK treatment group (all P＞0.05). The median survival time of patients with gastric cancer was significantly longer in CIK treatment group than in chemotherapy group (61 vs. 21, χ2=10.215, P=0.001). Compared with the patients treated by chemotherapy alone, the increased times of CIK treatment induced more survival rate and 2-5 years life spans (χ2=12. 461, P=0.006). Conclusions With the treatment that CIK cells are infused back into the elderly patients with gastric cancer, the risk of death is reduced, and the lifespan is prolonged, which is associated with the CIK cell treatment times.

After admission, they were found to suffer from ovarian teratomas with anti-NMDAR antibody positive in cerebrospinal fluid or serum. The patients were diagnosed as anti-NMDAR encephalitis associated with ovarian teratoma, and teratoma resection was performed.

Objective To investigate the clinical value of sB7-H3 in predicting the severity of acute pancreatitis at early stage. Methods By using the double antibody sandwich ELISA method, the level of plasma sB7-H3 was measured at 24h after onset of abdominal pain in 75 patients with acute pancreatitis (MAP30, MSAP20, SAP25), and 20 healthy persons were enrolled in the controlgroup.The sensitivity and specificity correlations of sB7-H3 in acute pancreatitis with severity degree , as well as with the clinical detection index , were also evaluated. Results The level of plasma sB7-H3 at 24 h in the AP group was significantly higher than that in the healthy control ( HC) group (t = 3.925, P = 0.0002), however, no significant difference was found between the MAP groep and the HC group (P>0.05). The levels of plasma sB7-H3 in the MSAP and the SAP group were significantly higher than that in the HC group (P<0.05和P<0.001)or the MAP group (P<0.05 和P<0.01);The level of plasma sB7-H3 in the SAP group was also markedly higher than that in the MSAP group (P < 0.01). sB7-H3 had a linear positive correlation with LDH、hs-CRP、WBC(P<0.05). ALB had a linear negative correlation with and Ca (S)(P<0.05). By the cutoff of sB7-H3, the sensitivity and specificity to judgethe above moderate pancreatitis were 88.9%and 83.3%,and to judgethe SAP were 96%and 96%. Conclusion sB7-H3 has important clinical value to judge the severity of acute pancreatitis at early time with high sensitivity and specificity , with a linear correlation with the clinical severity index.

ObjectiveTo assess gene chip application value in detecting pathogenic bacteria in intracranial infection cases.MethodsPrimers and probes aiming at the specific DNA sequences of 4 kinds of common pathogenic bacteria and 6 kinds of common drug resistance genes (DRGs) were designed and used to identify the bacteria and DRGs among 30 cerebrospinal fluid (CSF) specimens (12 positive,18negative in CSF culture) from patients with intracranial infection using multiplex polymerase chain reaction (mPCR) and gene chip.The results of gene detection were compared with those of CSF culture and drug sensitivity testing.ResultsBacteria were identified and DRGs were detected in 15 specimens; DRGs and 16S gene were detected in 8 specimens; neither bacterium nor DRG was detected in 7 specimens.ConclusionGene chip technique is characterized by its relative sensitivity and rapidity of detecting the pathogenic bacteria in CSF of intraeranial infection cases.

Objective To study the changes of subgroups of peripheral blood T lymphocytes in the patients infected with the 2009 pandemic influenza A ( H1N1 ) virus of different severity type. Method A total of 66 patients infected by H1N1 evidenced by RT-PCR admitted from September 2009 to January 2010 were divided into three groups: mild type ( B group, n = 47 ), cured patients of severe and critical severe type ( C group, n = 14) and died patients ( D group, n =5), according to the severity and prognosis. A total of 20 healthy volunteers served as control group( A group). Peripheral blood lymphocyte count, CD3+,CD4+ and CD8+ T lymphocyte count were detected by flow cytometry at the different time points. Fever duration and H1N1 virus negative time were compared. Statistical analysis were performed by using SAS version 9.13 software and the data were processed with ANOVA and SNK test. Results Lymphocyte count, CD3+,CD4+ and CD8+ T lymphocyte count declined in the early period in all the groups, and there were significant differences compared with A group (P＜0. 05), while rised with the clinical progression in group B and C,and those of C group were lower than B group ( P ＜ 0.05 ), but those of D group were always low. Fever duration and H1N1 virus negative time were (4.4 ± 1.6) days vs. (4.4 ± 1. 4) days, ( 12.9 ± 3. 1 ) days vs.( 10.2 ± 2.6) days and ( 15.2 ± 7.3 ) days vs. ( 13.3 ± 2.9 ) days respectively, and there were significant differences among the three groups ( P ＜ 0.05 ). Conclusions The cellular immune function was seriously damaged when patients were infected with H1N1. Further more, the changes of lymphocyte count, CD3+ , CD4+and CD8+ T lymphocyte count were tightly related with the degree of severity and prognosis. These findings can be used for clinical diagnosis and treatment.

Objective Using video tracking system to compare the effects of the locomotor activity between theophylline and caffeine in mice.Methods The KM mice were treated by theophylline and caffeine(both at 1,3,10,30,100 mg/kg)intraperitoneally respectively.After 10 min,the locomotor activity in the open field was recorded for 2 hours.The locomotor track,the total distance,the distances and distance ratio to total distance in central region were analyzed to evaluate the effects of these drugs on locomotor in mice.Results The mice administrated theophylline and caffeine both increased the total distances,and had similar bell-shaped dose-effect relationship.The distances reached the highest at 30 mg/kg theophylline((311±128)m)and 10 mg/kg caffeine ((279±89)m).The larger doses of caffeine inhibited the activity,and the total distance during 0～0.5 h was significantly decreased at the dose of 100 mg/kg(P＜0.05).Theophylline(30 and 100 mg/kg)and caffeine (30 mg/kg)significantly increased the distance ratio in central region(P＜0.01)and decreased the distance ratio in peripheral region(P＜0.01).Conclusion Theophylline and caffeine increase the total distance and the distance ratio in central region in mice,but have different valency and efficacy.

Objective To investigate the detection rate of malnutrition among post-stroke patients in community hospitals and unravel the relevant factors that precipitate malnutrition after stroke. Methods Based on 438 post-stroke patients who were admitted in community hospitals, we examined the demographic characteristics, the nutritional indices and the possible malnutrition related factors through a cross-sectional study.Results The detection rate of malnutrition among post-stroke patients was 52.7%. Group comparison through multivariate logistic regression analysis showed that there was a higher malnutrition detection rate in the post-stroke patients with multiple stroke attacks (three stroke attackes and above, OR = 11.00,95%CI 1. 14-106.34), higher NIHSS scores (group with NIHSS≥15, OR=7.09, 95% CI 2.90-17.36) , higher modified Rankin scales (group mRS 4-5, OR = 15. 77,95% CI 6.61-37.59) (trend test P<0.0001) .The risk of malnutrition was also correlated with the post-stroke depression, poorer family care, no early-stage rehabilitation, history of malignant tumors and severe alcoholism. Conclusions There is a high detection rate of malnutrition among post-stroke patients in community hospitals. There are many factors related to malnutrition among post-stroke patients in the community. More attention to controllable influencing factors would improve the prognosis of post-stroke patients.

OBJECTIVETo estimate the dose response relationship between cigarette smoking and hypertension in men based on restricted cubic spline method.

METHODSUnder the proportion to the population size, 38 520 subjects were randomly selected from May to August 2012 with cluster sampling method in urban and rural areas of Kunshan, China.Each participant received face-to-face interview with the standardized questionnaire, and physical examination.Restricted cubic spline was employed to estimate the dose response relation of cigarette smoking on the risk of hypertension.

RESULTSThe overall prevalence of cigarette smoking was 22.6% (8 691/38 520), prevalence of cigarette smoking in men was 46.1% (8 499/18 454). Multiple logistic regression analysis showed that current smoking (OR = 1.16, 95%CI:1.05-1.28) and previous cigarette smoking (OR = 1.32, 95%CI:1.07-1.63) were associated with hypertension after adjusted confounding factors (age, sex, body mass index, education, family income per month, urban or rural areas, physical activity and physical exercise) in men. After further adjusting drinking status, only previous cigarette smoking was associated with hypertension (OR = 1.28, 95%CI:1.04-1.58). The restricted cubic spline model indicated a linear dose-response relation between hypertension and cigarette smoking per day in men (non-linearity test P = 0.604 1).However, a non-linear dose response relation was found between duration of smoking (non-linearity test P < 0.000 1), smoking index (non-linearity test P = 0.009 9) and hypertension.

CONCLUSIONLong-term and heavy cigarette smoking is associated with hypertension in men.

Objective To explore the effect of low dose ionizing radiation on the thyroid of radiation workers in our country. Methods The literatures were searched of domestic and foreign journals from 1996 to 2017. A total of 15 studies involving 6332 participants were included. These studies were screened according to the inclusion and exclusion criteria. Three indicators of the thyroid function were analyzed in radiation workers, including triiodothyronine ( T3 ) , thyroxine ( T4 ) and thyroid stimulating hormone( TSH) . The Meta analysis was performed using Stata 14. 0 software. Results For radiation workers, the standardized mean difference (SMD) of T3 levels was -0. 32[95% CI ( -0. 61,-0. 04), P=0. 03?, lower than that of the control group. Univariate meta - regression analysis of sources of heterogeneity showed that only gender composition was related to heterogeneity of the study [ adjusted R-squared (Adj R2 ) =29. 99%, P =0. 03]. The SMD of T4 levels was -0. 49 [95%CI ( -0. 94,-0. 03), P=0. 04], lower than that of the control group. Only the gender composition was related to heterogeneity of the study[Adj R2 =26. 60%, P=0. 02]. However, the SMD of TSH levels was 1. 10 [95% CI (0. 32,1. 89), P=0. 006], higher than that of the control group. Conclusions The long term exposure of radiation workers to low dose ionizing radiation may lead to negative impact on thyroid. It is important to strengthen radiation protection of thyroid.
