Association between the risk of increase in total cholesterol and the risk of cholelithiasis： A bidirectional Mendelian randomization study / 临床肝胆病杂志

ObjectiveTo investigate the association between the risk of increase in total cholesterol （TC） and the risk of cholelithiasis by using bidirectional Mendelian randomization （MR）. MethodsThe open gwas public database was used to obtain the single nucleotide polymorphism data associated with TC and cholelithiasis， and a secondary data analysis was performed for all summary data of genome-wide association studies. The genetic loci closely associated with TC or cholelithiasis were selected as exposure or outcome variables， and the bidirectional MR analysis was performed using the methods such as Egger regression， Weighted median， IVW random effects model， and IVW fixed effects model， with odds ratio （OR） values for evaluating the causal relationship between TC and cholelithiasis. ResultsWith TC as the exposure and cholelithiasis as the outcome， TC-cholelithiasis had an overall OR value of 0.91 （95% confidence interval ［CI］： 0.85‍ ‍—‍ ‍0.97） before elimination of heterogeneity and 0.93 （95%CI： 0.89‍ ‍—‍ ‍0.97） after elimination of heterogeneity. With cholelithiasis as the exposure and TC as the outcome， TC-cholelithiasis had an overall OR value of 0.20 （95%CI： 0.06‍ ‍—‍ ‍0.65） before elimination of heterogeneity and 0.28 （95%CI： 0.10‍ ‍—‍ ‍0.83） after elimination of heterogeneity. There was a bidirectional causal relationship between genetically predicted TC and cholelithiasis. ConclusionThis study confirms the bidirectional causal relationship between TC and cholelithiasis. The risk of cholelithiasis decreases with the increase in alleles associated with the elevation of TC level； on the contrary， the risk of elevated TC level decreases with the increase in alleles associated with the onset of cholelithiasis.

Value of / 临床肝胆病杂志

Objective To investigate the association between Helicobacter pylori (HP) infection and newly named "metabolic associated fatty liver disease (MAFLD)" and the value of HP infection combined with traditional risk factors in predicting MAFLD. Methods A retrospective analysis was performed for the clinical data of 350 patients who were admitted to Affiliated Hospital of Inner Mongolia University for the Nationalities and underwent carbon-13 urea breath test from January 2017 to December 2021, and according to whether fatty liver disease was diagnosed by abdominal ultrasound, they were divided into MAFLD group with 190 patients and non-fatty liver disease group with 160 patients. The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. The binary Logistic regression analysis was used to investigate the risk factors for MAFLD. Results Compared with the non-fatty liver disease group, the MAFLD group had significantly higher body mass index ( t =8.73, P < 0.05), systolic blood pressure ( Z =-3.67, P < 0.05), diastolic blood pressure ( Z =-3.62, P < 0.05), triglyceride ( Z =-8.93, P < 0.05), fasting blood glucose ( Z =-9.13, P < 0.05), aspartate aminotransferase ( Z =-2.03, P < 0.05), gamma-glutamyl transpeptidase ( Z =-8.56, P < 0.05), proportion of male patients ( χ 2 =12.09, P < 0.05), and proportion of patients with hypertension ( χ 2 =37.91, P < 0.05), diabetes ( χ 2 =73.62, P < 0.05), overweight/obesity ( χ 2 =42.82, P < 0.05), hypertriglyceridemia ( χ 2 =59.12, P < 0.05), or HP infection ( χ 2 =4.53, P < 0.05), as well as a significantly lower level of high-density lipoprotein cholesterol ( Z =-6.81, P < 0.05). The Logistic regression analysis showed that fasting blood glucose (odds ratio [ OR ]=1.255, 95% confidence interval [ CI ]: 1.091-1.445, P < 0.05), HP infection ( OR =1.899, 95% CI : 1.048-3.440, P < 0.05), hypertension ( OR =2.589, 95% CI : 1.468-4.567, P < 0.05), diabetes ( OR =2.202, 95% CI : 1.123-4.315, P < 0.05), overweight/obesity ( OR =4.571, 95% CI : 2.308-9.052, P < 0.05), and hypertriglyceridemia ( OR =4.187, 95% CI : 2.411-7.271, P < 0.05) were risk factors for MAFLD, and it also showed that HP infection combined with traditional risk factors significantly increased the risk of MAFLD in subjects with diabetes, overweight/obesity, hypertriglyceridemia, and hypertension ( OR =12.267, 14.005, 7.911, and 7.364, all P < 0.05). Conclusion HP infection is associated with an increased risk of MAFLD, and its combination with traditional risk factors may further increase the risk of MAFLD.

Effects of multidisciplinary collaborative nursing combined with cognitive stimulation therapy on cognitive function, quality of life, and daily activities in patients with Alzheimer's disease.

Alzheimer's disease (AD) is a neurodegenerative condition that disrupts neuropsychological activity and hinders the development of mental capacity. Efficient AD therapy is a major challenge in biological studies. Alzheimer's condition cannot be cured with any particular medication. The purpose of this study is to investigate the impact of multidisciplinary collaborative nursing and cognitive stimulation therapy (MCN- CST) on daily activities, quality of life, and cognitive performance in AD patients. The inclusion/exclusion method is initially used to gather information about AD patients. Control and investigative teams were formed with its own set of functions. The control group gets a regular course of treatment, whereas, the investigation group receives MCN-CST. To ensure that our study is as practical and useful, we compare our findings to existing nursing approaches. The ANOVA and Chi-Square tests are used to assess the conditions of Alzheimer's patients. There was a scientifically significant improvement in the overall level of their medical condition after implementing MCN-CST. Nursing protocols developed MCN-CST is beneficial in improving patients' quality of life, cognitive function, and daily activities. It is encouraged to do intensive research using many samples drawn from a wider range of people.

Research on the application effect of cognitive stimulation therapy in patients with Alzheimer's disease based on expert consultation and semistructured interviews.

The awareness and utilization of psychological therapies for Alzheimer's disease have increased significantly in recent years. Limitations on the utilization of pharmacological therapy for Alzheimer's disease in China have corresponded with this surge in greater studies in the field. For individuals who have Alzheimer's disease, cognitive stimulation therapy (CST) is a quick self-help that is founded on the theories of quality and cognitive functioning. People with Alzheimer's disease often participate in cognitive behavioral programs; however, their expense has never been studied. Being part of a meta-analysis, we analyze the application effectiveness of a CST program that is based on recent research for Alzheimer's disease patients. A CST group therapy was given to 91 Alzheimer's patients, who resided in healthcare settings or the general public, multiple times per week for 8 weeks; the other 70 people with Alzheimer's disease got a medical therapy. Costs were computed, and resource utilization was tracked for 8 weeks both before and after the therapy. It was determined by a value study. In the value study, cognition and quality of life were the major and tertiary outcomes, respectively. Contours of cost-effectiveness and acceptance were drawn. It was driven based on expert consultation and semistructured interviews. In Alzheimer's disease, CST improves intelligence and standard of living, and there was no difference in implementation expenditures between the categories. Regarding both outcome metrics, there is a significant chance that CST seems to be more expensive than conventional therapy within realistic expectations. The efficacy of CST for Alzheimer's patients is superior to conventional treatment, and it could be the greater value. The outcomes contrast well with pharmacological studies for Alzheimer's. Many people with Alzheimer's disease may benefit significantly from CST groups.

Research advances in association between matrix metalloproteinases and liver fibrosis / 临床肝胆病杂志

Liver injury caused by various reasons can lead to the occurrence of liver fibrosis,which is the pathological process from chronic liver disease to liver cirrhosis.Liver fibrosis is caused by the increased synthesis and reduced degradation of extracellular matrix (ECM).ECM is mainly degraded by matrix metalloproteinases (MMP),and therefore,MMP play an important role in the progression and.diagnosis/treatment of liver fibrosis.This article reviews the research advances in the association between MMP and liver fibrosis.

Inhibition of corneal neovascularization by liposome mediated plasmid encoding endostatin with RGD sequence / 眼科研究

Background It has been demonstrated that αvβ3/αvβ5 and α5β1 integrins are overexpressed in neovascular tissue.Consequently,peptide containing the RGD (Arg-Gly-Asp) sequence,which exists in ligands of integrins,is effective in targeting therapeutic reagents to neovascular endothelium.ObjectivePresent study aims to investigate the antiangiogenetive effects of liposome mediated plasmid encoding endostatin with RGD sequence on alkali burn-induced corneal neovascularization (CNV) in rabbits.MethodsCNV models induced by alkali burn were established in 72 eyes of 36 New Zealand white rabbits by putting the filter paper with 1 mol/L NaOH at the central cornea for 20 seconds.The animal models were divided into four groups randomly.0.2mL of liposome and plasmid encoding RGD-ES complex (liposome mediated pCI-RGD-ES injection group),liposome and plasmid encoding ES complex (pCI-ES injection group),liposome and carrier plasmid (pCI) complex (pCI-ES injection group),and PBS were subconjunctivally injected respectively in the models from four groups twice a week for two weeks.The growth status of CNV was observed on day 1,3,7,14 after alkali burn under the slim lamp microscope.Experimental animals were sacrificed on the 3rd,7th and 14th day and the expression of VEGF in CNV was detected by immunohistochemistry.The number of corneal microvessels was counted based on the number of CNV cross-section under the light microscope.ResultsCNV area was significantly smaller in liposome mediated pCI-RGD-ES injection group and pCI-ES injection group compared with PBS group at different time points (P＜0.01),but no significant difference was seen in CNV area between pCI-ES injection group and PBS group at different time points (P＞0.01).The changes of number of corneal microvessels was followed a similar fashion as the change of CNV area.Expression of VEGF in cornea was obviously stronger in pCI-ES injection group and PBS group than liposome mediated pCI-RGD-ES injection group and pCI-ES injection group.ConclusionEndostatin with RGD sequence could effectively inhibit corneal neovascularization,and liposome is proved to be a potent carrier in gene transfer.

Prevention and Control of Intestinal Nematode Infection in Shanghai / 中国寄生虫学与寄生虫病杂志

Objective To evaluate the current status of intestinal nematode infection in Shanghai and make recommendations for further control activities Methods Retrospective review of the control program was made based on the change of nematode prevalence in Shanghai area since the 1950s, and challenges under the current situation were analysed. Results The intervention measures included chemotherapy, health education, sanitary disposal of human excreta and safe water supply. With the control strategy, socio\|economical development and the change of farming patterns, the prevalence of intestinal nematode infection in population was reduced by 88^5%, from 62^6% in 1955 to 8^2% in 2000. Among them, ascaris infection decreased by 89^0%, from 52^1% to 6^3%, hookworm infection decreased by 99^0%, from 12^9% to 0^1%, but pinworm infection was still as high as 18^9% in 1999. Conclusion Prevalence of nematode infection in Shanghai was considerably reduced. To match it with the current socio\|economical development in the Municipality, however, more needs to be done. Sustainable control activities and surveillance are recommended.
