Objective To systematically evaluate the influence of alcohol intervention on the outcome of rats and mice with ischemic stroke. Methods Databases including PubMed, EMbase, BIOSIS and CNKI were electronically searched from establishment dates of databases to June 2012 to retrieve animal experiments on the influence of alcohol intervention on the outcome of rats and mice with ischemic stroke. The relevant studies were identified according to the predefined inclusion and exclusion criteria, the data were extracted, and the quality was evaluated. Then meta-analysis was performed using RevMan 5.1 software. Results Eight studies were included. The results of meta-analysis showed that no significant difference was found between the alcohol intervention group and the control group (MD=?6.98%, 95%CI ?20.38% to 6.43%, P=0.31). However, compared with the control group, low dose of acute alcohol intervention (less than 2 g/kg) improved the prognosis of ischemic stroke with a significant difference (MD=?22.83%, 95%CI ?38.77% to ?6.89%, P=0.005), and highly-concentrated of chronic alcohol intervention worsened the cerebral ischemic damage of rats and mice with a significant difference (MD=24.06%, 95%CI 10.54% to 37.58%, P=0.000 5). Conclusion Low dose of acute alcohol intervention (less than 2 g/kg) could improve the prognosis of rats and mice with ischemic stroke which has the potential neuro-protective effects. However, highly-concentrated chronic alcohol intervention could worsen the cerebral ischemic damage. Due to the limitations of the included studies such as publication bias, the influence of alcohol intervention on the outcome of rats and mice with ischemic stroke could be overestimated.
Objective To compare the effectiveness of integrated traditional Chinese medicine (TCM) with Western medicine and Western medicine alone for acute episodes of withdrawal in alcoholism. Methods According to the criteria of alcohol dependence and acute alcochol withdrawal syndrome of Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-Ⅳ) , 62 consecutive patients were divided into two groups: 31 patients with odd numbers were allocated to the treatment group (4 patients were excluded because they left hospital early), 31 patients with even numbers were allocated to the control group. According to the four diagnostic methods of TCM, all patients in the treatment group were further divided into 4 types. The treatment group received valium, tiopronin, transfusion therapy and herbs (potion per day). The control group received the same therapy as the treatment group did but without oral herbs. Results Liver function, especially the difference between before and after treatment of GOT and γ-GT,the treatment group showed more improvement than the control group (P=0.046 and 0.001). The scores of anxiety and depression test, especially the HAMD, the treatment group showed more improvement than the control group (t=3.165, P=0.003). The treatment group used significantly less time than the control group (P=0.01), but no statistically significant difference was seen in the dosage of valium between the two groups (P=0.434). Conclusions The efficacy of integrated TCM with Western medicine is better than Western medicine alone for acute episodes of withdrawal in alcoholism.
Objective To investigate the influence of chronic alcohol ingestion on the severity of acute lung injury (ALI) induced by oleic acid and lipopolysaccharide (LPS).Methods Thirty-two SD rats were randomly administrated with alcohol or water for 6 weeks，then instilled with oleic acid and LPS to induce ALI or with normal saline as control.Thus the rats were randomly divided into two injury groups [ethanol group and water group] and two control groups [ethanol group and water group] (n=8 in each group). PaO2,Wet to dry lung weight ratio (W/D)，levels of γ-glutamylcysteinylglycine (GSH) and malonaldehyde (MDA) in the lung tissue were measured.Results Compared to corresponding control groups，the PaO2 and GSH significantly decreased，and the lung W/D and MDA level were significantly increased in the injury groups (all Plt;0.05).In the injury groups，the changes of above parameters were more significant in the alcohol group than thoe in the water group (all Plt;0.05)，except the lung W/D with no significant difference.Conclusion Chronic ethanol ingestion was relevalent to oxidation/ antioxidation imbalance and more severe lung injury in rats with severe septic after trauma,which suggests that chronic alcohol abuse could increase the severity of acute lung injury.
Objective
To review the research progress of alcohol-induced osteonecrosis of the femoral head (ONFH).
Methods
Recent literature concerning alcohol-induced ONFH was reviewed and summarized.
Results
Alcohol-induced ONFH accounte for approximately 1/3 of total ONFH. Alcohol intake and the incidence of ONFH has a significant dose-effect relationship. There are some correlations between alcohol-induced ONFH and lipid metabolism, secretion of corticosteroid, and some gene of alcohol or lipid metabolism.
Conclusion
The relationships between alcohol and lipid metabolism, and between alcohol and steroid are still the main direction of the research of ONFH. Gene level researches can not demonstrate the pathogenesis, therefore further research should be carried on.
Objectives To compare umbilical cord daily care protocol in the current clinical setting in which 75% alcohol sterile is used daily for the umbilical and surrounding skins with the WHO-recommended method (dry and clean). Methods A total of 283 full-term newborns were randomly divided into two groups: the trial group (n=181) receiving WHO “dry and clean” protocol that the umbilical cord was open to air (with losing clothes), cleaned by clear water instead of alcohol. The control group (n=102) used the traditional method that after the newborns’ bathing, the umbilical cord and surrounding skins were sterilized with 75% alcohol. The basic condition of the newborns, umbilical departure time and complications around the navel were assessed. And bacterial culture from the newborns’ skins was observed. Results There were no significant differences in departure time of the umbilical cord (7.64±3.29 day vs. 8.50±3.45 days t=1.82, Pgt;0.05), complications (6 patients with slight omphalitis in the trial group and 2 patients with slight omphalitis in the control group), and the skin flora culture between the two groups. The umbilical cord of the newborns dropped off safely. And no fever was found. Conclusion This study does not support that 75% alcohol can prevent the umbilical cord from being infected. Keeping the umbilical cord and surrounding skins dry is important for infection control.
Objective
To evaluate the disinfection efficacy of alcohol-based hand disinfectants for medical glove surface in continuous operation, and explore approaches of improving hand hygiene compliance.
Methods
Between March and July 2015, and between March and July 2016, all the nurses (n=5) in Blood Collection Room of Outpatient Department with many patients and frequent sterile operation needed were included in this study. Nurses wearing gloves for hand hygiene and disinfection between March and July 2016 were regarded as the observation group, and those who used alcohol-based disinfectants for routine hand hygiene without gloves between March and July 2015 were designated into the control group. The hand hygiene compliance was compared between the two groups. From March to July 2016, alcohol-based hand disinfectants were used for disinfection on the glove surface during continuous blood sampling by nurses with gloves on their hands. Fifty samples were collected respectively after the gloves were used for 1, 2, 5, 10, and 15 continuous times for blood sampling. Then, the samples were sent to the bacteriology room for culture.
Results
All of the 250 samples were qualified, and the bacterial colonies on the surface of gloves were equal to 10 cfu/mL2 or lower. NoStaphylococcus aureus,Escherichiacoli or other pathogens were detected on the glove surface. However, after the gloves were continuously used for 15 times, the gloves of two nurses could not meet the research criteria again because of significant sweating.
Conclusions
In the process of continuous blood sampling, it is effective to use alcohol-based hand disinfectants to disinfect the surface of medical gloves, which can promote hand hygiene compliance to a certain extent. However, there is a certain limit on the times of usage for medical gloves.
Objective
To explore the characteristics of cognitive impairment in patients with alcohol dependence, and analyze the related influencing factors.
Methods
The Montreal Cognitive Assessment Scale (MoCA) was used to evaluate the cognitive function of 65 alcohol dependent patients hospitalized between January 1st and December 31st, 2014. The features of cognitive impairment and related influencing factors were analyzed.
Results
The differences of MoCA attention and delayed recall between different drinking year groups had statistical significance (P<0.05). The correlations of drinking year with MoCA attention (r=–0.250,P=0.044), and with delayed recall (r=–0.326,P=0.008) were both negative. MoCA scores, naming, attention and delayed recall were different statistically among different age groups (P<0.05). The correlations of ages with MoCA scores (r=–0.429,P<0.001), naming (r=–0.261,P=0.035), attention (r=–0.391,P=0.001) and delayed recall (r=–0.461,P<0.001) were all negative. MoCA scores, the visuoconstructional skills, language, abstraction and delayed recall were significantly different among different education level groups (P<0.05). The correlations of education level with MoCA scores (rs=0.650,P<0.001), the visuoconstructional skills (rs=0.540,P<0.001), language (rs=0.486,P<0.001), abstraction (r=0.602,P<0.001) and delayed recall (rs=0.593,P<0.001) were all positive. Ages had an effect on MoCA scores by multiple linear regression analysis (P<0.01).
Conclusions
For alcohol dependent patients with cognitive impairment, cognitive function is correlated with drinking year, age and education level. The cognitive function is much serious in patients with older age and longer drinking years. This kind of patients should be focused on and intervened early.
The authors analysed the medical records of 30 patients with congenital cystic disease of the liver treated in this hospital and with a review of the article some problems of diagnosis and treatment are discussed. B-altrasonic scaner (B-US), computerized tomographic scanning and magnetic resonance imaging appeared to be most helpful in diagnosing and treating this disease. After comparing different treatments, such as aspiration .alcohol sclerotherapy, fenetration, cyst resection and partial hepatectomy, the arthors state the best results could be achieved by alcohol sclerotherapy under B-US guidence (6 cases) or fenestration (15 cases) with no postoperative complication. Malignant change was found in one patient of this group.
ObjectiveTo systematically review the relationship between maternal alcoholic consumption during pregnancy and the occurrence of childhood cancer in offspring. MethodsThe PubMed, Embase, Web of Science, Cochrane library, CNKI, WanFang Data, VIP, and CBM databases were electronically searched to obtain related case-control and cohort studies from inception to December 2024. Two reviewers independently screened articles, extracted data and assessed the risk of bias of the included articles. Meta-analysis was performed by using the RevMan 5.4 software. ResultsA total of 18 articles involving 9 childhood tumors' outcome were included. The results of meta-analysis showed that compared with women who never drink alcohol during pregnancy, alcoholic consumption during pregnancy increased the incidence risk of childhood cancer (OR=1.13, 95%CI 1.01 to 1.26, P=0.04). Subgroup analysis showed that alcoholic consumption during pregnancy significantly increased the incidence risk of acute leukemia (OR=1.17, 95%CI 1.06 to 1.30, P=0.002) and acute lymphocytic leukemia (OR=1.23, 95%CI 1.02 to 1.48, P=0.03). ConclusionThe current evidence suggests that alcoholic consumption during pregnancy significantly increases the incidence risk of childhood cancer in offspring, particularly acute leukemia and acute lymphocytic leukemia. Due to the limited quantity and quality of the included articles, more high-quality birth cohort studies are needed to verify the above conclusion.
