Acupuncture for treatment of tobacco withdrawal syndrome: systematic review and Meta-analysis / 中国针灸

OBJECTIVE@#To systematically review the efficacy of acupuncture for the treatment of tobacco withdrawal syndrome.@*METHODS@#The randomized controlled trials (RCTs) regarding acupuncture for treatment of tobacco withdrawal syndrome were searched in CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane, Medline and EMbase databases. The search period was from January 1st of 2011 to December 31st of 2021. After data extraction and bias risk assessment of the included literature, the Meta-analysis was performed using RevMan5.4.1 software.@*RESULTS@#Totally 23 RCTs were included, including 2 120 patients. The Meta-analysis results showed that compared with medication, acupuncture showed no significant difference at improving Fagerström test for nicotine dependence (FTND) score (MD=0.16, 95%CI: -0.08, 0.41), heaviness of smoking index (HSI) score (MD=0.11, 95%CI: -0.13, 0.36), Minnesota nicotine withdrawal scale (MNWS) score (MD=0.12, 95%CI: -0.11, 1.35), questionnaire of smoking urges (QSU) score (MD=-0.30, 95%CI: -2.78, 2.18), Hamilton depression scale (HAMD) score (MD=0.76, 95%CI: -1.54, 3.06), abstinence rate (RR=0.95, 95% CI: 0.82, 1.10) and effective rate (RR=1.01, 95%CI: 0.95, 1.07). Acupuncture was superior to sham acupuncture in reducing MNWS score (MD=-4.88, 95%CI: -5.21, -4.55, P<0.000 01). Acupuncture was superior to cognitive behavioral therapy in reducing FTND score (MD=-1.41, 95%CI: -1.74, -1.08), MNWS score (MD=-4.28, 95%CI: -5.31, -3.25) and increasing abstinence rate (RR=2.19, 95%CI: 1.39, 3.45, P<0.000 01, P<0.001).@*CONCLUSION@#Acupuncture could effectively improve tobacco withdrawal syndrome, increase abstinence rate and effective rate. Limited by the quantity and quality of the included studies, this conclusion needs to be verified by more studies.

Impacts of nicotine metabolite rate and acupuncture frequency on smoking cessation: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the efficacy of different acupuncture frequencies in tobacco-dependent patients and explore the impact of nicotine metabolite rate (NMR) on smoking cessation in the intervention with acupuncture.@*METHODS@#A total of 120 cases of tobacco-dependent patients were randomly divided into a high-frequency group (60 cases, 12 cases dropped off) and a low-frequency group (60 cases, 6 cases dropped off). In the two groups, smoking cessation counseling was provided prior to acupuncture. Acupuncture was applied to Baihui (GV 20), Lieque (LU 7), Zusanli (ST 36), etc. Additionally, electric stimulation was added at Lieque (LU 7) and Zusanli (ST 36), with continuous wave, 15 Hz in frequency. The duration of treatment was 8 weeks in either group. In the high-frequency group, the treatment was given 5 times weekly from week 1 to week 4, and was 3 times weekly from week 5 to week 8. In the low-frequency group, the treatment was given 3 times weekly from week 1 to week 4, and was twice a week from week 5 to week 8. The immediate withdrawal rate, persistent withdrawal rate, the score of Fagerstrőm test for nicotine dependence (FTND) before and after treatment, as well as the score of Minnesota nicotine withdrawal scale (MNWS) in 1 and 8 weeks of treatment were compared among the patients with high and low NMR between the two groups separately. The Logistic regression analysis was used to screen the influencing factors of smoking cessation in the intervention with acupuncture.@*RESULTS@#After treatment, there was no statistical significance of the differences in the immediate withdrawal rate (35.4% [17/48] vs 29.6% [16/54]) and the persistent withdrawal rate (33.3% [16/48] vs 25.9% [14/54]) between the high-frequency group and the low-frequency group (P>0.05). The difference in withdrawal rate had no statistical significance between high and low NMR patients (P>0.05). FTND scores after treatment were lower than those before treatment (P<0.01) and MNWS scores were lower than those in 1 week of treatment (P<0.01) in the two groups. However, the differences had no statistical significance between the two groups and between the patients with high NMR and low NMR (P>0.05). Age, education level and NMR were the influencing factors of smoking cessation in the intervention with acupuncture (P<0.05).@*CONCLUSION@#Acupuncture with different frequencies has no obvious impact on the efficacy in tobacco-dependent patients. The lower nicotine metabolite rate in individuals, the better efficacy of acupuncture. The smokers with high nicotine metabolite rate may obtain a better effect of cessation in the high-frequency intervention with acupuncture.

Expression of mdm2 Genes in Nephroblastoma in Childhood and Its Relationship with Clinical Pathological Parameters / 实用儿科临床杂志

Objective To study the expression of mdm2 genes in nephroblastoma in children and relationship between mdm2 gene and clinical pathological parameters.Methods The protein expressions of mdm2 in 24 cases of nephroblastoma were detected with S-P immunohistochemical method.The relationships between mdm2 expression and clinicopathological parameters were analyzed.Results The positive rates of mdm2 in 24 cases of nephroblastoma were correlated with lymph node metastasis,clinical stage and tumor differentiation.There was a positive relationship between mdm2 protein expression and clinicopathological parameters such as lymph node metastasis,clinical stage and degree of differentiation(P
