Objective To analyze the acupoint selection law of acupuncture and moxibustion for postherpetic neuralgia(PHN)with R language data mining technology.Methods The clinical research literature on acupuncture and moxibustion treatment of PHN included in CNKI,Wanfang Data,VIP and CBM from January 1,2010 to July 1,2023 was retrieved,and the database was established by Excel 2016.R language was used to statistically analyze the frequency of acupoint usage,meridians,locations,specific acupoints,etc.Through association rule analysis and clustering analysis,the characteristics and law of acupoint selection for acupuncture and moxibustion treatment of PHN were obtained.Results A total of 198 articles were included,including 83 acupoints,with a total frequency of 714 times.The high-frequency acupoints include Ashi acupoint,Jiaji acupoint and Yanglingquan.The commonly used meridians were gallbladder meridian,spleen meridian and large intestine meridiam.The acupoints were mostly in the upper and lower limbs,with the Wushu acupoints,Yuan acupoints and Xiahe acupoints being the most common.The core acupoint was Ashi acupoint,Jiaji acupoint,Hegu,Quchi,and 9 sets of association rules and 5 effective clusters were obtained.Conclusion The most commonly used acupoints for acupuncture and moxibustion treatment of PHN are Ashi acupoint,Jiaji acupoint,Hegu and Quchi,which mainly follow the principle of combining local acupoint selection with distal acupoint selection.

Objective To clarify the distribution of traditional Chinese medicine(TCM)pattern and its associated risk factors after percutaneous coronary intervention(PCI),and evaluate the re-porting quality of existing studies to guide future research standardization. Methods English databases including PubMed,Cochrane Library,and Web of Science,as well as Chinese databases including China National Knowledge Infrastructure(CNKI),China Scientific Journal Database(VIP),and Wanfang Database were searched to retrieve papers about PCI.The time span for the paper retrieval was set from the foundation of the databases to October 1,2023.Statistical analyses were performed using Stata 12 and Python(V 3.9).The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)statement was used to assess the reporting quality of included studies. Results Overall,1 356 articles were selected,and 40 cross-sectional studies were included with 10 270 participants.The most common TCM patterns before,one to two weeks after,and six months to one year after PCI was Qi stagnation and blood stasis(n=261,36.45%),inter-twined phlegm and blood stasis(n=109,27.18%),and Qi deficiency and blood stasis(n=645,37.03%),respectively.Smoking[odds ratio(OR)=1.15,95%confidence interval(CI)(0.83-1.47),I2=24.7%,P=0.257],pattern of congealing cold and Qi stagnation[OR=4.62,95%CI(1.37-7.86),I2=61.6%,P=0.074],and low-density lipoprotein(LDL)[OR=1.38,95%CI(0.92-1.85),I2=12.2%,P=0.286]were risk factors for restenosis.Hypertension[OR=7.26,95%CI(3.54-14.88),I2=91.6%,P=0.001],and overweight[i.e.,body mass index(BMI)>23][OR=1.20,95%CI(1.07-1.35),I2=85.3%,P=0.009]were significant risk factors of concomi-tant anxiety. Conclusion This systematic review and meta-analysis revealed that patients with different TCM pattern types have distinct characteristics and risk factors after PCI.More high-quality studies are warranted to provide supportive evidence for future research and clinical practice.
