Objective To systematically assess the efficacy and safety of acupuncture in treating type 2 diabetes.Methods Related literature was retrieved with a computer. After the data were sifted out from the literature according to the established criteria, they were collected and crossly checked by two researchers independently. The data were input to RevMan5.2 for statistical analysis. Results A total of ten studies were included with a total of 743 patients. The results of Meta analysis showed 1) Post-treatment total efficacy rate was higher in the acupuncture or combined acupuncture and medicine group than in the control group [OR=3.60, 95%CI (2.11,6.13)] and there was a statistically significant difference (Z=4.71,P<0.00001); 2) Post-treatment range of decrease in fasting blood glucose (FBG) was significantly higher in the experiment group than in the control group [WMD=-1.20,95%CI (-1.38,-1.02)] and there was a statistically significant difference (Z=12.88,P<0.00001); 3) Post-treatment range of decrease in 2-h postprandial blood glucose (2hPBG) was significantly higher in the experiment group than in the control group [WMD=-1.27, 95%CI (-1.47,-1.06)] and there was a statistically significant difference (Z=12.02,P<0.00001).Conclusion Clinically acupuncture or combined acupuncture and medicine is more effective than Chinese herbal medicine or Western medication alone in treating T2DM and has no toxic and side effects.

Objective:To explore the utility of adenosine stress-rest gated myocardial perfusion imaging (G-MPI) in evaluation of left ventricular (LV) myocardial perfusion, heart function, and synchronization in patients with multivessel coronary artery disease after coronary artery bypass grafting (CABG).Methods:Fifty-five patients (42 males, 13 females, age (59.3±9.0) years) with multivessel coronary artery disease who underwent CABG surgery in Yan′an Hospital Affiliated to Kunming Medical University between January 2021 and June 2023 were retrospectively collected. All of them underwent G-MPI (one-day method) one week before and six months after CABG. Paired t-test or Wilcoxon signed rank test was used to compare LV myocardial perfusion parameters including summed stress score (SSS), summed rest score (SRS), and summed different score (SDS) before and after CABG, as well as cardiac function parameters (LV ejection fraction (EF), LV end-diastolic volume (EDV), LV end-systolic volume (ESV), stroke volume (SV), peak filling rate (PFR)), and LV mechanical contraction synchronization parameters such as phase histogram bandwidth (PHB) and phase standard deviation (PSD). Differences of the changes of parameters after CABG compared to baseline (Δ) between adenosine stress imaging and rest imaging were also compared by Wilcoxon signed rank test. The relationships between rest LVEF, rest PFR and myocardial perfusion parameters were analyzed by Spearman rank correlation analysis. Results:After CABG, the SSS, SRS, and SDS were significantly lower than those before surgery (6(3, 12) vs 16(9, 23), 1(0, 9) vs 4(1, 15), 3(1, 5) vs 8(6, 12); z values: 6.37, 4.84, 6.24, all P<0.001); postoperative rest/stress LVEF(60%(49%, 67%), 58%(48%, 68%)) and PFR (3.67(3.12, 4.28), 3.23(2.77, 4.43) EDV/s) significantly increased compared with preoperative values (51%(33%, 62%), 53%(27%, 61%); 2.76(2.08, 3.52), 2.83(1.86, 3.62) EDV/s; z values: 3.23-5.58, all P<0.01); postoperative rest/stress LVEDV and LVESV were significantly lower than those before surgery ( t values: 6.40, 5.27; z values: 5.33, 5.40; all P<0.001); rest/stress PHB (45°(35°, 70°), 53°(44°, 113°)) and PSD (14.7°(10.9°, 27.3°), 20.0°(14.6°, 33.8°)) were significantly lower than those before surgery (60°(45°, 131°), 83°(58°, 198°), 20.4°(16.0°, 49.1°), 27.2°(19.6°, 60.4°); z values: 4.19-4.81, all P<0.001). The ΔSSS was greater than the ΔSRS, and the ΔPFR was greater in rest imaging than that in stress imaging ( z values: 6.24, 2.77, both P<0.05). Rest LVEF, PFR were negatively correlated with SSS and SRS ( rs values: from -0.741 to -0.431, all P<0.05). Conclusion:The LV myocardial perfusion, function, and mechanical contraction synchronicity information obtained from adenosine stress-rest G-MPI can be used to evaluate the recovery after CABG, which may help to better identify patients who may have adverse cardiac events.
