RESUMEN
INTRODUCTION: Acupuncture and related acupoint therapies have been widely used for smoking cessation. Some relevant systematic reviews (SRs) have been published. There is a need to summarize and update the evidence to inform practice and decision-making. METHODS: Eight databases were searched from their inception to December 2023. SRs, any randomized controlled trials (RCTs) comparing acupuncture therapies with sham acupuncture, pharmacotherapy, behavioral therapy, or no treatment, were included. The primary outcome was the abstinence rate. AMSTAR-2 was employed to assess the quality of SRs. An updated meta-analysis was conducted based on SRs and RCTs. Data were synthesized using risk ratios (RR) with 95% confidence intervals (CIs). The GRADE approach was employed to assess the certainty of the updated evidence. RESULTS: Thirteen SRs and 20 RCTs outside of the SRs were identified. The SRs were of low or very low quality by AMSTAR-2. Sixteen (80%) RCTs were at high risk of performance bias. Eight acupuncture and related acupoint therapies were involved. The short-term (≤6 months) abstinence rate outcome was summarized as follows. Most SRs suggested that filiform needle acupuncture or acupressure had a better effect than sham acupuncture, but the findings were inconsistent. The updated meta-analysis also suggested that filiform needle acupuncture was more effective than sham acupuncture (RR=1.44; 95% CI: 1.02-2.02; I2 = 66%; low certainty; 9 RCTs, n=1358). Filiform needle acupuncture combined with acupressure was comparable to nicotine patches (RR=0.99; 95% CI: 0.74-1.32; low certainty; 6 RCTs, n= 524). Acupressure was superior to counseling (RR=1.46; 95% CI: 1.14-1.87; I2=5%; low certainty; 8 RCTs, n=595). No serious adverse events were reported in these SRs or RCTs. CONCLUSIONS: Low certainty evidence suggests that filiform needle acupuncture and auricular acupressure appear to be safe and effective in achieving short-term smoking cessation. However, long-term follow-up data are needed.
RESUMEN
Background: Intrahepatic cholangiocarcinoma (iCCA) is the second most common primary liver cancer. While multiple risk factors for iCCA have been established, metabolic diseases (obesity, diabetes, NAFLD, dyslipidemia, and hypertension) and other risk factors, including smoking and drinking, are still controversial due to their potential confounders. Here, Mendelian randomization (MR) analysis was performed to identify the causal relationship between them. Method: In this study, we obtained GWAS data related to exposures from corresponding large genome-wide association studies. Summary-level statistical data for iCCA were obtained from the UK Biobank (UKB). We performed a univariable MR analysis to identify whether genetic evidence of exposure was significantly associated with iCCA risk. A multivariable MR analysis was conducted to estimate the independent effects of exposures on iCCA. Results: Univariable and multivariable MR analysis based on the large GWAS data indicated that there is little evidence to support the genetic role of metabolic factors, smoking, drinking, and NAFLD in iCCA development (P >0.05). In contrast to most current studies, their impact on iCCA development, if any, might be smaller than we thought. The previous positive results might be due to the comorbidities between diseases and potentially unavoidable confounding factors. Conclusion: In this MR study, we found no strong evidence to support causal associations between metabolic factors, NAFLD, smoking, drinking, and iCCA risk.
RESUMEN
OBJECTIVE: To observe the effect of acupuncture of intraorbital and extraorbital acupoints on apoptosis and expression of Bax, Bcl-2 and Caspase-3 proteins of retinal ganglion tissue in rabbits with nonarteritis anterior ischemic optic neuropathy (NAION), so as to reveal its mechanism underlying improvement of NAION. METHODS: Female New Zealand rabbits were randomly divided into four groups: model, intraocular needling (ION), extraocular needling (EON), IONï¼EON groups (nï¼5 per group), and the 5 healthy eyes of those rabbits in the model group were selected to be used as the control group. The NAION model of the right eye was established by photodynamic stroke method. For ION group, acupoints "Jingming" (BL1), "Chengqi" (ST1) and "Qiuhou" (EX-HN7) were needled, and for EON group, "Cuanzhu" (BL2), "Yuyao" (EX-HN4) and "Qiaoming" (EX) were needled with filiform needles, followed by retaining the needles for 30 min. For IONï¼EON group, the 6 acupoints were needled simutaneously. The treatment was conducted once daily for 3 days. The apoptosis of retinal ganglion tissue was detected by using TUNEL fluorescence labeling, and the expression of Bax, Bcl-2 and active Caspase-3 in the retinal ganglion were detected by immunohistochemistry. RESULTS: Following modeling and compared with the control group, the number of the apoptotic cells, and the expression levels of Bax and Caspase-3 proteins, as well as the ratio of Bax/Bcl-2 were significantly increased in the model group (P<0.01), while the expression of Bcl-2 was significantly decreased (P<0.01). After intervention, the number of the apoptotic cells in the ION, EON and IONï¼EON groups, and the ratio of Bax/Bcl-2 in EON and IONï¼EON groups, and the expression of Caspase-3 proteins in the ION and IONï¼EON groups were significantly down-regulated (P<0.01, P<0.05), and the expression levels of Bcl-2 in both EON and IONï¼EON groups were significantly up-regulated in comparison with the model group (P<0.01). No significant changes were found in the expression levels of Bax in the 3 needling groups relevant to the model group (P>0.05). CONCLUSION: Acupuncture of intraorbital and extraorbital acupoints can reduce apoptosis of retinal ganglion in NAION rabbits via inhibiting the activation of Caspase-3 protein and ratio of Bax/Bcl-2, and up-regulating the expression of Bcl-2 protein.
