Objective To investigate the expression of COX-2 in human cervical cancer and explore their relationship between the COX-2 expression and the clinicopathologic characteristic of cervical cancer. Methods The published studies were searched in the CBMdisc (1979 to 2009), CNKI (1979 to 2009), VIP (1989 to 2009) and WANFANG Database (1982 to 2009), and other relevant journals were also hand searched, to identify all the relevant case-control trials. The quality of the included studies was assessed. The Cochrane Collaboration’s software RevMan 4.2.10 was used to test the heterogeneity, overall effect and publication bias of the combined studies. Results A total of 9 studies were recruited. As for the positive rate of COX-2 expression, significant differences was tested between cervical cancer vs. normal cervical tissues, lymph node metastasi vs. non-lymph node metastasi, clinical stages I-II vs. clinical stages III-IV, cell differentiation G1 vs. cell differentiation G2-G3 and cervical squamous cell carcinoma vs. adenocarcinoma with OR (95%CI) at 28.03 (9.53 to 82.50), 5.16 (3.36 to 7.93), 0.53 (0.33 to 0.84), 3.11 (1.86 to 5.22) and 5.00 (2.68 to 9.35) respectively. Conclusions According to the domestic evidence, higher COX-2 expression might be associated with cervical cancer. However, more high quality case-control studies are expected for further study.
Objective To investigate the correlation between RUNX3 expression and human gastric cancer, as well as its clinically pathologic features. Methods Such databases as PubMed, EMbase, VIP, WanFang Data and CBM were searched from their inception to February 28th, 2013 to collect case-control studies about the correlation between RUNX3 expression and human gastric cancer, as well as its clinically pathologic features, and the relevant references of the included literature were also retrieved. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the methodological quality. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 6 case-control studies were included, which included 405 cases in the gastric cancer group and 185 cases in the normal gastric mucosa group. The results of meta-analysis showed that, RUNX3 expression was lower in the gastric cancer group than the normal gastric mucosa group, with a significant difference (OR=0.07, 95%CI 0.04 to 0.12, Plt;0.000 01); it was also lower in the subgroup of gastric cancer accompanied with lymph node metastasis than that without lymph node metastasis (OR=0.37, 95%CI 0.23 to 0.61, Plt;0.000 1); but it was higher in the subgroup of gastric cancer that had infiltrated into serosa than that had not, with a significant difference (OR=3.92, 95%CI 2.29 to 6.71, Plt;0.000 01); and it was also higher in the subgroup of well differentiated gastric cancer that the moderately and poorly differentiated, with a significant difference (OR=0.36, 95%CI 0.22 to 0.58, Plt;0.000 1). Conclusion RUNX3 expression is notably correlated to gastric cancer and its clinically pathologic features. For the quantity and quality limitation of the included studies, this conclusion still needs to be further proved by performing more high quality studies.
Objective To investigate the association of central obesity (Waist-to-Hip Ratio) and carotid intima-media thickness (IMT) in Han, Uygur and Kazak female adults in Xinjiang. Methods Four-stage stratified cluster random sampling was used to select adult samples aged over 35 years in different districts in Xinjiang, and then a study was conducted using a questionnaire, physical exams (including blood pressure, height, weight, waist length, and hip length) and lab biochemical tests, while IMT was measured by ultrasound. According to WHR, the people were divided into two groups (WHR≥0.9 group and WHRlt;0.9 group). Results 14 618 cases had been surveyed, including 7 294 female adults (Han: 2 793 cases; Uygur: 2 490 cases; and Kazak: 2 011 cases). Among the same nationality, the WHR≥0.9 group had higher levels of systolic pressure, diastolic pressure, urea nitrogen, fasting blood-glucose, triglyceride and total cholesterol than the WHRlt;0.9 group, with significant differences (P=0.000). The two groups were the same in creatinine, high-density lipoprotein cholesterol and low density lipoprotein with no significant differences (Pgt;0.05). Among all people, the WHR≥0.9 group had slightly thicker IMT than the WHRlt;0.9 group (P=0.17). Among the Han nationality, the two groups were the same in IMT (P=0.23). Uygur’s IMT and Kazak’s IMT in the WHR≥0.9 group were thicker than that in the WHRlt;0.9 group (P=0.00). Among different populations, in the WHR≥0.9 group, Kazak’s IMT was the thickest, while Uygur’s IMT was the thinner, with significant differences (P=0.00). Within the WHR≥0.9 group, in different age groups, Kazak’s IMT was the thickest; except in the group of aged over 75 years, there were significant differences among other subgroups, the Han group, and the Uygur group (all Plt;0.05). The result of logistic regression showed that, WHR≥0.9 was an independent risk factor of IMT thickening among the three groups. Conclusion WHR increase is positively associated with IMT among the three nationalities. Also, WHR≥0.9 was an independent risk factor of IMT in all the three nationalities.
Objective To systematically review the efficacy and safety of different duration of dual antiplatelet therapies in patients undergoing new-generation drug-eluting stents implantation. Methods Such databases as MEDLINE, The Cochrane Library (Issue 2, 2015), EMbase, CBM, CNKI and WanFang Data were searched to collect studies on the different duration of dual antiplatelet therapies in patients undergoing new-generation drug-eluting stents implantation from inception to April 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. Results Six trials were included. The results of meta-analysis showed: compared with 12 months dual antiplatelet therapy group, the incidence of bleeding in the 6 months dual antiplatelet therapy group was lower (OR=0.48, 95%CI 0.26 to 0.89, P=0.02). There were no significant differences in incidence of myocardial infarction, all cause mortality, stroke and stent thrombosis between two groups. Compared with 24 months dual antiplatelet therapy group, the incidence of stent thrombosis in the 12 months dual antiplatelet therapy group was higher (OR=2.50, 95%CI 1.13 to 5.61, P=0.02), but the incidence of bleeding in 12 months dual antiplatelet therapy group was lower (OR=0.25, 95%CI 0.07 to 0.89, P=0.03). No significant differences were found in the incidence of myocardial infarction, all cause mortality and stroke between 12 months dual antiplatelet therapy group and 24 months dual antiplatelet therapy group. Conclusions 6 months dual antiplatelet therapy following new-generation drug-eluting stent implantation is relatively more safe and efficacy. There is significant increase of incidence of bleeding in 12 or 24 months dual antiplatelet therapy. Due to the limited quantity and quality of included studies, the above results are needed to be validated by more high quality studies.
Objective To investigate the general situation of self-management behavior of patients with cirrhosis, and analyze its influencing factors. Method From January to June 2015, the in-patients with liver cirrhosis were recruited from Gastroenterology Ward of a comprehensive hospital in Chengdu city by convenience sampling method, and a series of questionnaires were used in the research, including self-management behavior scale, social support scale (SSRS), quality of life questionnaire (WHOQOL-BREF) and sociodemographic characteristics. Results One hundred and sixty-eight patients were enrolled. The self-management behavior of patients with cirrhosis scored an average of 50.4±11.3, which was in the medium level. Self management behavior was positively and significantly correlated with social support (r=0.488, P<0.001) and the overall quality of life (r=0.554, P<0.001). Multiple linear regression indicated that the gender and course of the disease were two influencing factors. Moreover, female experienced better self-management behavior than men (t=27.090, P<0.001); and the longer the course of the disease was, the better the self-management behavior could be found (t=34.057, P<0.001). Conclusion We should strengthen the health education of self-management in patients with cirrhosis, and make full use of the patients’ social support system, so as to improve the patients’ self-management behavior as well as the treatment of diseases and their quality of life.
ObjectiveTo deeply discuss the home care experience of parents of children with epilepsy, analyzed the current status of care ability and the real influencing factors, and provide a basis to improve their care ability.MethodsDescriptive research was used to conduct in-depth interviews with parents of 14 children with epilepsy who were admitted to the Children's Hospital of Zhengzhou University from December 2019 to January 2020, and data analysis was performed by using the generic analysis method.ResultsThe home care experience of parents of children with epilepsy includes four themes: weak nursing ability, physical and mental fatigue, weak support system, and expectation of medical professional support.ConclusionMedical staffs should combine the needs of parents of children with epilepsy and the influencing factors of care ability to carry out health education guidance of online and offline epilepsy knowledge and care skills to improve their care ability.
ObjectiveTo explore the effect of type 2 diabetes mellitus (T2DM) on the vascular endothelial function of patients with heart failure with mid-range ejection fraction (HFmrEF), and the impact of endothelial function damage on the long-term prognosis of HFmrEF. Metohds87 patients with T2DM and heart failure with mid-range ejection fraction (T2DM-HFmrEF), 98 patients with HFmrEF alone, and 70 healthy control who had been hospitalized at the department of cardiology of the First Affiliated Hospital of Xinjiang Medical University from December 2018 to January 2020 were included. The levels of serum TNF-α, IL-6, vWF, eNOs and E-selectin were determined by enzyme-linked immunosorbent assay. The oxidative stress and vascular endothelial function related indicators of the 3 groups were analyzed. The primary endpoint (all-cause death, exacerbation of heart failure and rehospitalization, or exacerbation of heart failure) and secondary endpoint events (non-fatal myocardial infarction, stable and unstable angina pectoris, or stroke) were followed up for 1 year after discharge.ResultsThe levels of TNF-α, IL-6, vWF, and E-selectin in the HFmrEF combined with diabetes group were higher than those in the HFmrEF without diabetes group (P<0.05). Multivariate Cox regression analysis showed that BNP (HR=1.001, P=0.036), eNOs (HR=1.04, P<0.001), and IL-6 (HR=1.002, P<0.001) were related to the primary end point of all patients with HFmrEF. Glycated hemoglobin (HR=1.37, P=0.046), E-selectin (HR=1.01, P=0.003), vWF (HR=1.02, P=0.017), and IL-6 (HR=1.006, P=0.005) were related to the secondary end point of all patients with HFmrEF. The results of subgroup analyze showed that E-selectin (HR=1.014, P=0.012) and IL-6 (HR=1.008, P=0.007) were related to the secondary endpoint events in the HFmrEF combined with diabetes group, but were not related to the secondary end point events of the non-diabetic group (P>0.05).ConclusionsOxidative stress and vascular endothelial function damage may be involved in the pathogenesis of T2DM-HFmrEF. Serum IL-6 and E-selectin levels are related to the endpoint events in T2DM-HFmrEF patients.
Aortic aneurysm and dissection are critical cardiovascular diseases that threaten human life and health seriously. No pharmacological treatment can effectively prevent disease progression. The imbalance of aortic wall cells and non-cellular components leads to structural or functional degeneration of the aorta, which is a prerequisite for disease occurrence. As the important non-cellular component, extracellular matrix (ECM) is crucial to maintain the aortic structure, function, and homeostasis. Abnormal production of elastin and collagen, destruction of cross-linking between elastic fibers and collagen fibers, and the imbalance of metalloproteinase and inhibitors leads to excessive degradation of ECM proteins, all of which have destroyed the structure and function of aorta. It will provide more ideas for disease prevention and treatment by learning ECM proteins and their metabolic mechanism. Here, we focus on the ECM proteins that have been reported to be involved in aortic aneurysm and dissection, and discuss the regulatory mechanism of metalloproteinase and inhibitors.
ObjectiveTo analyze and summarize the clinical and video EEG (VEEG) characteristics of tuberous sclerosis (TSC) with epilepsy.MethodsClinical data of 30 children with TSC who met the revised diagnostic criteria of TSC in 2012 from Jan. 2016 to May 2019 in Zhengzhou Children’s Hospital were collected, including 29 children with epileptic seizures. The characteristics of skin lesions, imaging, seizures and long-term VEEG were analyzed retrospectively.ResultsThe mean age was (2.88 ± 2.64), 12 males and 18 females, 1 case of lumbar acid as the first symptom, 29 cases with epilepsy as the first symptom, the incidence of epilepsy is high, and the onset age is less than 1 year old; TSC can cause different degrees of cognitive impact; depigmentation or milk coffee spots are the most common skin changes in young children; TSC with infantile spasm has a high incidence; children younger than 10 years old may have lesions of other organs except nervous system lesions. However, the incidence of other organ lesions was relatively low. Most of TSC children with epilepsy were accompanied by abnormal EEG discharge.ConclusionThe clinical characteristics of TSC with epileptic seizures are various, and early diagnosis is of great significance.
