Objective To evaluate the clinical efficacy and safety of Compound Danshen Dripping Pills combined with Tirofiban in alleviating myocardial ischemia-reperfusion injury(MIRI)in patients with acute ST-segment elevation myocardial infarction(STEMI)after percutaneous coronary intervention(PCI).Methods Ninety-two patients with acute STEMI of qi stagnation and blood stasis syndrome who were admitted to the Chest Pain Center of Shunde Hospital,Guangzhou University of Chinese Medicine between March 2023 and October 2023 were equally randomized into a control group and a treatment group using a random number table,with 46 cases in each group.The control group received intracoronary loading dose of Tirofiban during PCI combined with postoperative intravenous micro-pump injection of Tirofiban,while the trial group additionally received Compound Danshen Dripping Pills orally,the treatment course lasted for 4 weeks.Before treatment or immediately after surgery and after 4 weeks of treatment,the two groups were observed in the changes in traditional Chinese medicine(TCM)syndrome scores,cardiac function parameters[including left ventricular ejection fraction(LVEF),cardiac output(CO),and left ventricular end-diastolic diameter(LVEDD)],and levels of inflammatory markers of C-reactive protein(CRP)and brain natriuretic peptide(BNP),as well as safety indicators such as liver and kidney function and coagulation parameters in both groups.The peak values of myocardial necrosis markers of creatine kinase-MB(CK-MB)and troponin I(cTnI)and other myocardial enzyme profiles between the two groups were compared.After treatment,the TCM syndrome efficacy of improvement,the therapeutic effect on improving ST-segment resolution(STR)of electrocardiogram,and the incidence of adverse cardiovascular events in both groups were assessed.Results(1)There were 3 patients dropping out during the trial,with a final total of 89 cases included in the efficacy analysis(44 cases in the control group and 45 cases in the trial group).(2)After 4 weeks of treatment,the total effective rate in the trial group was 95.56%(43/45)and that in the control group was 79.55%(35/44).Intergroup comparison by chi-square test showed that TCM syndrome efficacy in the trial group was significantly superior to that in the control group(P＜0.05).(3)After 4 weeks of treatment,the total effective rate for improving STR in the trial group was 93.33%(42/45)and that in the control group was 75.00%(33/44).Intergroup comparison(tested by chi-square test)demonstrated that the trial group had significantly stronger STR improvement efficacy than the control group(P＜0.05).(4)After 4 weeks of treatment,the serum levels of CRP and BNP in both groups were lower than those immediately after surgery(P＜0.05),and the trial group exhibited significantly greater reductions in both CRP and BNP levels than the control group(P＜0.01).(5)The peak values of myocardial necrosis markers of CK-MB and cTnI in the trial group were significantly lower than those in the control group,with statistically significant differences(P＜0.05).(6)After 4 weeks of treatment,the trial group showed significant improvements in LVEF and CO compared to immediate postoperative values(P＜0.05),while LVEDD demonstrated an improving trend without statistical significance(P＞0.05).The control group showed no significant improvements in LVEF,CO,or LVEDD(P＞0.05).The intergroup comparison revealed that the trial group had significantly better improvements in LVEF and CO than the control group(P＜0.05 or P＜0.01).(7)After 4 weeks of treatment,both groups showed reductions in the scores of chest pain,chest tightness,palpitations,emotional depression,hypochondriac distension,and dull complexion,as well as the total syndrome scores when compared to pretreatment values(P＜0.05),and the trial group presented significantly greater reductions than the control group(P＜0.05).(8)No statistically significant differences were shown in the parameters of liver/kidney function or coagulation between the two groups before and after treatment(P＞0.05).(9)The incidence of postoperative adverse cardiovascular events in the control group was 13.64%(6/44)and that in the trial group was 6.67%(3/45),and the intergroup comparison(tested by Fisher's exact test)showed no statistically significant difference(P＞0.05).Conclusion The combination therapy of Compound Danshen Dripping Pills and Tirofiban demonstrates significant efficacy in improving TCM syndromes,ST-segment elevation,myocardial necrosis markers,and cardiac function in STEMI patients after PCI,with good safety.

Objective:To explore the influencing factors of immune checkpoint inhibitor-related pneumonitis (CIP) in lung cancer patients caused by programmed cell death 1 receptor (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors.Methods:A retrospective analysis was conducted on clinical data of lung cancer patients treated with PD-1/PD-L1 inhibitors in the First Affiliated Hospital of Guangzhou Medical University from January 2018 to June 2022. Patients with CIP were included in the CIP group, and those who did not experience any immune-related adverse events during the same period were screened in a 1∶1 ratio and included in the control group. The clinical characteristics in patients of the 2 groups were compared and influencing factors of CIP were analyzed using binary logistic regression method. The effect sizes were the odds ratio ( OR) and its 95% confidence interval ( CI). Results:A total of 246 patients (123 in the CIP group and 123 in the control group) were entered in the analysis, including 208 males and 38 females, aged (63±9) years with a range of 32 to 86 years. The diagnosis was non-small-cell lung cancer in 234 patients and small cell lung cancer in 12 patients. There were no statistically significant differences in age, gender, history of respiratory diseases, tumor histological types, TNM stages, and types of immune checkpoint inhibitors used in patients between the 2 groups (all P>0.05). Compared with the control group, patients in the CIP group had a lower body mass index [(21.5±3.2) kg/m 2vs. (22.6±3.0) kg/m 2, P=0.004], higher proportion of patients with Eastern Cooperative Oncology Group Performance Scale (ECOG-PS) ≥2 points[39.0% (48/123) vs. 22.0% (27/123), P=0.004], higher proportion of patients with a history of radiation therapy [25.2% (31/123) vs. 13.8% (17/123), P=0.024], and lower proportion of patients with combination therapy with chemotherapy/targeted drugs[82.9%(102/123) vs. 97.6%(120/123), P<0.001]. Before immunotherapy, the peripheral blood interleukin-1β and interferon-α were lower [1.97 (1.04, 2.74) ng/L vs. 2.40 (1.75, 4.03) ng/L, P=0.021; 2.08 (0.89, 3.00) ng/L vs. 2.76 (1.97, 3.94) ng/L, P=0.012], lymphocyte count was lower [1.4(1.0, 1.8)×10 9/L vs. 1.5(1.2, 2.1)×10 9/L, P=0.030], and the neutrophil-to-lymphocyte ratio was higher [3.85 (2.50, 6.40) vs. 3.11 (2.25, 4.61), P=0.006] in patients of the CIP group than those in the control group. The binary logistic regression analysis showed that baseline ECOG-PS ≥2 points ( OR=3.400, 95% CI: 1.180-9.798, P=0.023) and combination of PD-1/PD-L1 inhibitors and chemotherapy/targeted therapy ( OR=0.047, 95% CI: 0.005-0.454, P=0.008) were independent influencing factors for the occurrence of CIP. Conclusion:The ECOG-PS ≥ 2 points before immunotherapy is an influencing factor for CIP, and the combination with chemotherapy/targeted therapy may reduce the risk of developing CIP in patients treated with PD-1/PD-L1 inhibitors.

Objective: To compare bioelectrical impedance analysis (BIA) and dual energy X ray absorptiometry (DXA) for measuring body mineral content (BMC) of children and adolescents, and to provide a basis for BIA to accurately measure BMC in children and adolescents. Methods: By using the convenience sampling method, among 1 469 children and adolescents aged 7-17 were recruited in Guangzhou from April to May 2019, the BMC was measured by DXA and BIA. The intraclass correlation coefficient ( ICC ) and Bland Altman analysis were used to evaluate the agreement between BIA and DXA. Bland Altman analysis was performed on log transformed data. The BMC was categorized into age and specific tertiles, and the agreement between methods was evaluated based on the kappa coefficients. Treating the BMC with DXA as the dependent variable, a prediction model was constructed for correcting the BIA measure. Results: The ICC s were 0.93 and 0.94 for boys and girls, respectively. In Bland Altman analysis, the limits of agreements for the BIA to DXA ratio were wide in boys and girls, ranging from 0.27-0.76 and 0.17-0.72, respectively. The kappa coefficients for categorized BMC levels were 0.57 and 0.45 for boys and girls, respectively, showing a fair to good degree of agreement. When sub grouped by BMI, the kappa coefficients for all BMI groups of boys and overweight girls were all >0.75 , with an excellent agreement. The prediction models for boys and girls were as follows: BMC DXA =-0.51+0.44× BMC BIA + 0.06× Age +0.02× BMI ; and BMC DXA =-0.55+0.43× BMC BIA +0.06× Age +0.02× BMI , respectively. The R 2 for models of boys and girls were 0.87 and 0.87, respectively. Conclusion The agreement between BIA and DXA was poor for measuring BMC, but acceptable when evaluating the categorized BMC levels, suggesting the BIA may be applied in assessment of the BMC levels when compared to the age and gender specific population. Additionally, the prediction model for correcting BMC by BIA fis well to the measurement by DXA.

Objective:To analyze the current status of body composition and development patterns of children and adolescents aged 6-17 years in Guangzhou.Methods:This was a cross-sectional study involving 8 169 school students from 3 elementary schools and 3 middle schools in Guangzhou from March to December 2019.The fat-free mass (FFM) and fat mass (FM) were measured by the bioelectrical impedance analysis.The fat-free mass index (FFMI) and fat mass index (FMI) were calculated via the height standardization. T test was used to compare quantitative variables between groups.The growth pattern of body composition was described using the Hattori chart. Results:A total of 4 431 boys (54.24%) and 3 738 girls (45.76%) were involved in this study.FFM and FM both increased with age between boys and girls.Except for boys aged 11 years, FFM in boys were significantly higher than that in girls with the same age (all P<0.05). In the age of 7-10 years, FM in boys were significantly higher than that in girls with the same age, while it was significantly higher in girls aged 12 years and older than that of boys at the same age (all P<0.05). The Hattori chart showed that the difference in body composition between genders occurred after 11 years old.In contrast to girls, increases in the weight and body mass index (BMI) in boys were mainly attributed to the FFM development. Conclusions:The development of FFM and FM in children and adolescents varies with age, accompanied with the gender-specific features.FFM in boys is higher than that of girls at the same age.The weight gain in boys is mainly attributed to the development of fat-free tissues, and thus the utility of BMI may lead to the overestimation of obesity.

Objective:Surgical site infection (SSI) is the most common infectious complication after emergency abdominal surgery (EAS). To a large extent, most SSI can be prevented, but there are few relevant studies in China. This study mainly investigated the current situation of SSI occurrence after EAS in China, and further explored risk factors for SSI occurrence.Methods:Multi-center cross-sectional study was conducted. Clinical data of patients undergoing EAS in 33 hospitals across China between May 1, 2019 and June 7, 2019 were prospectively collected, including perioperative data and microbial culture results from infected incisions. The primary outcome was the incidence of SSI after EAS, while the secondary outcomes were postoperative hospital stay, ICU occupancy rate, length of ICU stay, hospitalization cost, and mortality within postoperative 30 days. Univariate and multivariate logistic regression models were used to analyze the risk factors of SSI after EAS.Results:A total of 660 EAS patients aged (47.9±18.3) years were enrolled in this study, including 56.5% of males (373/660). Forty-nine (7.4%) patients developed postoperative SSI. The main pathogen of SSI was Escherichia coli [culture positive rate was 32.7% (16/49)]. As compared to patients without SSI, those with SSI were more likely to be older (median 56 years vs. 46 years, U=19 973.5, P<0.001), male [71.4% (35/49) vs. 56.1% (343/611), χ 2=4.334, P=0.037] and diabetes [14.3% (7/49) vs. 5.1% (31/611), χ 2=5.498, P=0.015]; with-lower preoperative hemoglobin (median: 122.0 g/L vs. 143.5 g/L, U=11 471.5, P=0.006) and albumin (median: 35.5 g/L vs. 40.8 g/L, U=9452.0, P<0.001), with higher blood glucose (median: 6.9 mmol/L vs. 6.0 mmol/L, U=17 754.5, P<0.001); with intestinal obstruction [32.7% (16/49) vs. 9.2% (56/611), χ 2=25.749, P<0.001], with ASA score 3-4 [42.9% (21/49) vs. 13.9% (85/611), χ 2=25.563, P<0.001] and with high surgical risk [49.0% (24/49) vs. 7.0% (43/611), χ 2=105.301, P<0.001]. The main operative procedure resulting in SSI was laparotomy [81.6%(40/49) vs. 35.7%(218/611), χ 2=40.232, P<0.001]. Patients with SSI experienced significantly longer operation time (median: 150 minutes vs. 75 minutes, U=25 183.5, P<0.001). In terms of clinical outcome, higher ICU occupancy rate [51.0% (25/49) vs. 19.5% (119/611), χ 2=26.461, P<0.001], more hospitalization costs (median: 44 000 yuan vs. 15 000 yuan, U=24 660.0, P<0.001), longer postoperative hospital stay (median: 10 days vs. 5 days, U=23 100.0, P<0.001) and longer ICU occupancy time (median: 0 days vs. 0 days, U=19 541.5, P<0.001) were found in the SSI group. Multivariate logistic regression analysis showed that the elderly (OR=3.253, 95% CI: 1.178-8.985, P=0.023), colorectal surgery (OR=9.156, 95% CI: 3.655-22.937, P<0.001) and longer operation time (OR=15.912, 95% CI:6.858-36.916, P<0.001) were independent risk factors of SSI, while the laparoscopic surgery (OR=0.288, 95% CI: 0.119-0.694, P=0.006) was an independent protective factor for SSI. Conclusions:For patients undergoing EAS, attention should be paid to middle-aged and elderly patients and those of colorectal surgery. Laparoscopic surgery should be adopted when feasible and the operation time should be minimized, so as to reduce the incidence of SSI and to reduce the burden on patients and medical institutions.
