Objective To observe the clinical efficacy of acupuncture plus Chinese medicine iontophoresis in treating dry eye syndrome.Method Sixty-two patients with dry eye syndrome were randomized into a treatment group and a control group, 31 cases in each group. The treatment group was intervened by acupuncture plus Chinese medicine iontophoresis, while the control group was intervened by artificial tears. After 4-week treatment, the changes of tear secretion, tear film break-up time (BUT) and symptoms score were observed, and the clinical efficacies were compared.Result The total effective rate was 87.1% in the treatment group versus 61.3% in the control group, and the between-group difference was statistically significant (P<0.05). The total symptoms score, tear secretion and BUT were significantly changed after the treatment in both groups (P<0.05). After the treatment, the total symptoms score, tear secretion and BUT in the treatment group were significantly different from those in the control group (P<0.05).Conclusion Acupuncture plus Chinese medicine iontophoresis is an effective method in treating dry eye syndrome.

Objective To compare the outcomes of off-pump versus on-pump CABG.Methods From 2002 to 2008,CABG was performed in 105 patients aged 80 years and over,including 45 without cardiopulmonary bypass (CPB) or off-pump (OP) CABG (OPCAB) and 60 with CPB (onpump CABG).The outcomes were compared between two groups.Results The mean ICU stay was (37.1±30.3) h in OPCAB group and (60.6±58.2) h in on-pump CABG group (P＜0.01).Average ventilator-assisted time was (10.8±9.7) h for OPCAB group versus (22.3±35.7) h for onpump CABG group (P＜0.01).Postoperative atrial fibrillation occurred in 31.1％ of OPCABG patients and 41.7 ％ of on-pump CABG patients (P＜0.01).The mortality rate was 5.0％ in OPCABG group versus 8.3％ in on-pump CABG group (P＜0.05).Conclusions OPCABG is a safe and efficient method of myocardial revascularization in the elderly patients with lower morbidity and complications.

ObjectiveTo investigate the effects and mechanism of rosuvastatin on the expression of tissue factor in cultured human monocyte-macrophages cells which was induced by oxidized low density lipoprotein(ox-LDL).MethodsThe human monocyte-macrophages cells were divided into four groups:control group,ox-LDL group,Poly-inosine monophosphate (Poly Ⅰ) group,rosuvastatin group.The expression of LOX-1mRNA and TF mRNA was assayed by RT-PCR.The ELISA was performed to determine the protein concentration of TF.ResultsCompared with control group,the expression of LOX-1 mRNA and TF mRNA was increased in the ox-LDL group[ (3.25156±0.15772) vs (1±0) ; (2.522451±0.138967) vs (1±0) ],and it was in a concentration-dependent manner (P＜0.01).Compared with the expression of LOX-1 mRNA in the Poly-inosine monophosphate group and rosuvastatin group,TF mRNA were decreased in the ox-LDL group[ (2.95139±0.157253) vs(3.25156±0.15772) ; (2.877343±0.156558) vs(3.25156±0.15772) ; (1.811956±0.169699) vs (2.522451±0.138967) ; (1.687701±0.174647) vs (2.522451±0.138967)],and it was in a concentration-dependent manner(P＜0.05).Compared with control group,the expression of TF in the ox-LDL group was increased [(207.7233±1.154701) vs (184.8467±0.871799) ],and it was in a concentration-dependent manner (P＜0.01).Compared with the Poly-inosine monophosphate group and rosuvastatin group [(197.8733±1.505003) vs (207.7233±1.154701) ;(202.9567±2.722744)vs(207.7233±1.154701) ],the expression of TF in the ox-LDL group were decreased,and it was in a concentration-dependent manner (P＜0.05).ConclusionsLOX-1 may be responsible for the expression of TF in human monocyte-macrophages cells induced by ox-LDL.Rosuvastatin is able to down-regulate the expression of LOX-1mRNA in human monocyte-macrophages cells through oxLDL,and TF mRNA and TF expression can be reduced.

Objective To explore the relationship between serum tumor markers and cervical cancer by using Logistic regression, and to further establish the diagnosis model of squamous cell carcinoma antigen (SCC) in cervical cancer by using chi-squared automatic interaction detector (CHAID) analysis of decision tree.Methods Total of 581 cases of cervical cancer,342 cases of cervical benign diseases and 341 cases of healthy controls who detected tumor markers in Taizhou Hospital of Zhejiang during 2010-2013, were retrospectively studied.The test results of carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA), SCC, and alpha fetoprotein (AFP) were reviewed.The Logistic regression were firstly used in screening the related tumor markers of cervical cancer, and then the CHAID method of decision tree was used in determining the values of the related tumor markers on the diagnosis of cervical cancer.The SCC elevated cases of uterine disease from January 2014 to December 2014 were collected to verify the diagnostic value of SCC in cervical cancer patients.Results Logistic regression analysis showed that among the 5 tumor markers which might be associated with cervical cancer, SCC was the only one which had statistical significance between cervical cancer and cervical benign diseases (Wald x2 =22.120,P =0.000), the OR and its 95％ CI was 1.900 (1.454-2.483).With the SCC numerical increases, the proportion of patients with cervical cancer also gradually increased, when SCC ＞ 2.20 μg/L, the positive predictive value was 94.7％.In 284 cases of SCC higher than 2.20 μg/L who considered as uterus related diseases, there were 270 cases (95.1％) who were eventually confirmed as cervical cancer.Conclusion There was a good diagnostic value of SCC for cervical cancer patients.

Objective To investigate the relationship between metabolic syndrome (MS) and education level in Su-Xi-Chang area to provide evidence for healthcare policy making. Methods A clustered sampling of 6798 subjects from Su-Xi-Chang areas of Jiangsu Province was included. Questionnaires and physical examinations were completed to collect clinical data. Logistic regression was used to analyze weather education level could be an independent risk factor of MS. Results Significant differences were found in waist circumstance (WC) ,systolic blood pressure (SBP) and fasting blood glucose (FBG) among participants with different education level. Significant differences were also existed in triglyceride and diastolic blood pressure (DBP) between subjects with higher and lower education level ( P＜0. 05 ). In single-factor or multivariate analysis, education level was negatively correlated with the prevalence of MS (P＜0. 05 ). Conclusions Education level may be an independent risk factor of MS. People with low and moderate education level have higher risk of MS. Therefore,it is recommended that health-related information should become an integral part of the compulsory education system.

Objective To investigate the relationship between metabolic syndrome (MS) and diet style in the elderly. Methods The 781 old people were consecutively selected. Related data were collected by means of questionnaires and physical examinations. And logistic regression was performed to analyze if moderate and high fat diet were risk factors of MS. Results The total prevalence rate of MS in old people was 40. 7%, with 36.7% in old males and 55.4% in old females,and the prevalence rate of MS was higher in old women than in old men (P=0. 000). The significant differences in waist circumferences among three groups of low, moderate and high-fat diet [(86.0±9.3) cm vs. (88.8±8.5) cm vs. (90. 0±7.9) cm, respectively (all P＜0.05)]were found. Fasting blood glucose showed a significant difference between two groups of low and high-fat diet, with the results of (5.78 ± 0.98) mmol/L and (6.27 ± 1.80) mmol/L, respectively ( P＜0. 05 ). The logistic regression analysis showed that odds ratio for people with moderate and high-fat diets were 1. 541 ( 1. 092-2. 174) and 2. 293 ( 1. 317-3. 994), respectively (P＜0.05), which indicated that moderate and high-fat diet was independent risk factors for MS in old people. Conclusions Both moderate and high-fat diets are risk factors of MS in old population, low fat diet with food balance is recommended to old population in order to decrease the prevalence of MS.
