ABSTRACT
Objective:To systematically compare the analgesic efficacy of pericapsular nerve group (PENG) block and fascia iliaca compartment block (FICB) after hip fracture surgery.Methods:Databases including Pubmed, Embase, Cochrane, CNKI, Wanfang and VIP were searched for randomized controlled trials involving comparison of the analgesic efficacy of PENG block and FICB after hip fracture surgery from inception to August 2022. The primary outcome was the postoperative pain score, and the secondary outcome was the amount of postoperative analgesics and incidence of postoperative adverse reactions. The data were analyzed using Revman 5.4 software.Results:Eight studies were included ( n=374), and the pain score at rest 30 min after block was significantly lower in PENG group than in FICB group ( MD=-0.35, 95% CI -0.60--0.11, I2=14%, P<0.05). There was no statistically significant difference between PENG group and FICB group in pain scores at rest and during activity at 6, 12, 24 and 48 h after operation ( P>0.05). Compared with FICB group, the amount of analgesics used was significantly reduced at 24 and 48 h after operation in PENG group ( MD=-9.10, 95% CI -19.11-0.91, I2=95%, P<0.05). There was no statistically significant difference in the incidence of adverse reactions after operation between the two groups ( P>0.05). Conclusions:PENG block provides better efficacy when used for analgesia following hip fracture than FICB.

ABSTRACT
Objective@#To to describe the prevalence of cyberbullying and its relation with suicide among college students in Taiyuan,and to provide scientific basis for promoting the physical and mental health of teenagers.@*Methods@#Using the method of multi-stage stratified random cluster sampling, a total of 4 012 people were randomly selected from 2 colleges (departments) in sophomore and junior years of 6 universities in Shanxi Province during May to Jul.2018, and the survey contents included basic demographic characteristics, internet usage, cyber bullying, and suicide behavior.@*Results@#The total report rate of cyberbullying among college students was 19.42%, among which the report rates of cyberbullying vicitimization cyberbullying and both cyberbulling penetration and victimization were 1.60%,11.49％ and 6.16％(247/4 012), respectively.The overall reported rate of suicidal behavior was 10.87%(436/4 012).Logistic analysis indicated that cyberbullying victimization,as well as cyberbulling penetration and victimization were risk factors for suicidal behavior（OR=1.82，2.97，P<0.05).@*Conclusion@#Cyberbullying behaviors of college students, especially those who suffer from cyberbullying or the simultaneous implementation and suffering of cyberbullying, may increase the risk of suicide. Therefore, while reducing the occurrence of cyberbullying, we should pay more attention to the mental health of students suffering from cyberbullying and reduce the occurrence of health-risk behaviors such as suicide.
ABSTRACT
Objective@#To explore the relationship between childhood maltreatment and suicide ideation of college students,so as to provide basis for physical and mental health of college students.@*Methods@#Students from 6 universities in Shanxi Province(3 854 college students provided eligible questionniare for childhood abuse and 3 882 for suicidal ideation) were selected by multi-stage random cluster sampling from May to July 2018, the Chinese Version of the Childhood Trauma Questionnaire and the Self-rating Idea of Suicide Scale were used in the survey.@*Results@#Of all subjects,42.4% had at least one kind of abuse experience in childhood and 3.9% had suicidal ideation in the past week. By chi square test,the detection rate of suicidal ideation of college students who suffered physical abuse,emotional abuse,sexual abuse,physical neglect,emotional neglect in childhood was higher than that of college students without maltreatment (χ2=13.78，12.97，17.10，56.56，66.58，P<0.01)；Spearman correlation analysis showed that there was a positive correlation between each type of maltreatment in childhood and college students’ suicidal ideation(r=0.06，0.06，0.07，0.12，0.13，P<0.01)；Multivariate Logistic regression model found that after controlling other influencing factors,physical neglect and emotional neglect in childhood were independent risk factors for suicide ideation of college students (OR=2.18,2.07,P<0.05).@*Conclusion@#Physical neglect and emotional neglect in childhood can increase the risk of college students’ suicidal ideation. Paying enough attention and care to them in early childhood may help to prevent their suicidal ideation in adulthood.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the differences in the therapeutic effects on relapsing-remitting multiple sclerosis (RRMS) at remission stage between acupuncture at acupoints and shallow needling therapy at the nearby points.</p><p><b>METHODS</b>Forty-two patients of RRMS were randomized into an observation group and a control group, 21 cases in each one. In the observation group, besides the basic treatment, acupuncture was applied according to's empirical prescriptions as "the empirical ten needles" "thirteen needles of the governor vessel" "twelve needles of hand and foot" as well as the symptomatic points. In the control group, the basic treatment was given. Additionally, the shallow needling therapy was given at the sites 0.2 to 0.3lateral to the acupoints, and the arrival ofwas not required. In the two groups, acupuncture was given once a day for 5 days a week, continuously for 2 weeks. At the intervals of 2 weeks, totally the treatment of 3 months was required. The follow-up visit was conducted for 2 years. Separately, the scores of the expanded disability status scale (EDSS) before and in follow-up after treatment, the annual recurrent rate before and after treatment and recurrent interval after treatment were observed in the patients of the two groups.</p><p><b>RESULTS</b>In the observation group, EDSS scores in 3-month and 6-month follow-up were reduced as compared with those before treatment (both<0.05) and those in the 12-month and 24-month follow-up were increased (both<0.05). In the control group, EDSS scores were increased in tendency continuously in 3-month, 6-month, 12-month and 24-month follow-up (all<0.05). In each time point of follow-up, the different value of EDSS scores in the observation group was lower than that in the control group (<0.05,<0.01). The annual recurrent rates after treatment were reduced as compared with those before treatment in the two groups (both<0.01) and the value in the observation group was lower than that in the control group (<0.01). The recurrent interval in the observation group was longer than that in the control group[(441.56±65.37) d vs (382.78±59.33) d,<0.01].</p><p><b>CONCLUSIONS</b>Acupuncture achieves the significant therapeutic effects on RRMS at the remission stage.

ABSTRACT
Objective:To investigate the effects of high thoracic epidural anesthesia (HTEA) on the cerebral blood flow (CBF) and hippocampal apoptosis-related proteins Bcl-2 and Bax during global cerebral ischemia and reperfusion (GCI) in rats.Methods:Fifteen-minute global ischemia was established by 4-vessel occlusion and epidural catheterization was performed through T4-5 intervertebral spaces in adult male Wistar rats.According to the different drugs infused into the epidural space,the rats were randomly divided into four groups:Sham group (0.9 ％ NaC1),Sham-HTEA group (0.25 ％ bupivacaine),GCI group (global cerebral ischemia,0.9 ％ NaC1) and HTEA group (global cerebral ischemia,0.25 ％ bupivacaine).And 0.25 ％bupivacaine or 0.9 ％ saline (20 μL·h-1) was infused continuously to the thoracic epidural space from 15 minutes before ischemia to 24 hours after reperfusion.Mean arterial pressure (MAP),heart rate (HR) and cerebral blood flow (CBF) were determined until 2 hours after reperfusion,and the hippocampal Bcl-2 and Bax proteins at 24 hours after reperfusion were examined by Western-blot.Results:Compared with the GCI group,HTEA group has no significant difference on MAP and HR during ischemia and 2 hours after reperfusion,andcompared with the Sham group,MAP in GCI group increased in ischemia 0 min and decreased in reperfusion 0 min.The CBF in HTEA group was significantly lower than that in GCI group (123.1％± 35.2％ vs 177.5％± 32.4％,P＜0.01) in reperfusion 10 min,and higher than that in GCI group during the hypoperfusion of 60 to 120 minutes after reperfusion (P＜0.05),and the ratio of Bax/Bcl-2 in hippocampus was significantly decreased in HTEA group 24 hours after reperfusion (P＜0.01).Conclusions:Continuous HTEA infusion of 0.25 ％ bupivacaine 20 μL ·h-1 could maintain the hemodynamic stability,and improve the CBF of hypoperfusion period in rats,as well as reduce the ratio of Bax/Bcl-2 at 24 hours after reperfusion.
ABSTRACT
ObjectiveTo develop a quantitative method for simultaneously determining multi-components in Rhei Radix et Rhizoma using one chemical reference substance.MethodsThe contents of multi-components were calculated by the UV relative correction factors (RCFs) of chrysophanol,physcion,and rhein to emodin.ResultsThe values of RCFs at 274 nm for rhein,chrysophanol,and physcion to emodin were 0.712,0.674,and 1.051.The calibration curves were linear over the ranges of 0.02-4.08,0.02-4.12,0.07- 12.92,and 0.02-3.68 μg/mL for rhein,emodin,chrysophanol,and physcion,respectively.The contents of emodin in 18 samples were determined by the extemal standard method,and the contents of the other three anthraquinone aglycones were calculated according to their RCFs.ConclusionNo significant difference is found in comparison with the classical method,indicating that the RCFs have high reliability within their linear ranges and could be used in quality control of Rhei Radix et Rhizoma.The quantitative analysis of multi-component with a single marker is especially suitable for herbal medicines containing unstable or hard to be purified components as quality control markers.
