Objective:To investigate the relationship between the timing of pulmonary surgery and postoperative pulmonary complications (PPCs) after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.Methods:Sixty-eight American Society of Anesthesiologists Physical Status classification Ⅰor Ⅱ patients of either sex, with body mass index of 18-30 kg/m 2, who were first infected with SARS-CoV-2 after December 2022, undergoing elective thoracoscopic partial pneumonectomy from January to May 2023, were included in this prospective cohort study. The patients were divided into 2 groups ( n=34 each) according to the time between the date of surgery and SARS-CoV-2 infection: 5-10 weeks group and 11-16 weeks group. The preoperative persistent symptoms and dyspnea before operation were recorded. The serum concentrations of interleukin-6 and tumor necrosis factor-alpha were determined by enzyme-linked immunosorbent assay at 1 day before operation and 2 h and 1 and 2 days after operation. The white blood cell count and serum C-reactive protein concentration were measured at 1 day before operation and 1 and 2 days after operation. The occurrence of PPCs and length of postoperative hospital stay were recorded. Logistic regression was used to analyze the relationship between PPCs and timing of pulmonary surgery after SARS-CoV-2 infection. Results:Two patients in each group were excluded from the study because of conversion to thoracotomy. Thirty-two patients were finally included in each group. Compared with 5-10 weeks group, the ratio of preoperative persistent symptoms and dyspnea was significantly decreased, the serum concentrations of interleukin-6, tumor necrosis factor-alpha and C-reactive protein and white blood cell count were decreased at each time point after operation, the incidence of PPCs and postoperative pulmonary infection was decreased, and the length of postoperative hospital stay was shortened in 11-16 weeks group ( P<0.05). Multivariate logistic regression analysis showed that short time from the date of surgery to infection ( OR=1.754, 95% confidence interval[ CI] 1.509-2.038, P<0.001), preoperative persistent symptoms ( OR=2.523, 95% CI 2.047-3.110, P<0.001), preoperative dyspnea ( OR=1.875, 95% CI 1.406-2.500, P<0.001) and high white blood cell count at 1 day after surgery ( OR=0.676, 95% CI 0.651-0.701, P<0.001) were independent risk factors for PPCs. Conclusions:The risk of PPCs is lower in the patients undergoing pulmonary surgery at 11-16 weeks after SARS-CoV-2 infection than at 5-10 weeks after infection. Short time from the date of surgery to infection is an independent risk factor for PPCs.

Objective:To investigate the relationship between intramuscular adipose tissue index (IATI) calculated from computed tomography images at transverse process of the first lumbar and all-cause mortality in maintenance dialysis patients, and to provide a reference for improving the prognosis in these patients.Methods:It was a multicenter retrospective cohort study. The clinical data of patients who received maintenance hemodialysis or peritoneal dialysis treatment from January 1, 2017 to December 31, 2019 in 4 grade Ⅲ hospitals including Zhongda Hospital Affiliated to Southeast University, Taizhou People's Hospital Affiliated to Nanjing Medical University, Affiliated Hospital of Yangzhou University, and the Third Affiliated Hospital of Soochow University were retrospectively collected. IATI was calculated by low attenuation muscle (LAM) density/skeletal muscle density. The receiver-operating characteristic curve was used to determine the optimal cut-off value of IATI, and the patients were divided into high IATI group and low IATI group according to the optimal cut-off value. The differences of baseline clinical data and measurement parameters of the first lumbar level between the two groups were compared. The follow-up ended on December 23, 2022. The endpoint event was defined as all-cause mortality within 3 years. Kaplan-Meier survival curve and log-rank test were used to analyze the survival rates and the differences between the two groups. Multivariate Cox regression analysis models were used to analyze the association between IATI and the risk of all-cause mortality in maintenance dialysis patients. Multivariate logistic regression analysis model was used to analyze the influencing factors of high IATI.Results:A total of 478 patients were eligibly recruited in this study, with age of (53.55±13.19) years old and 319 (66.7%) males, including 365 (76.4%) hemodialysis patients and 113 (23.6%) peritoneal dialysis patients. There were 376 (78.7%) patients in low IATI (<0.42) group and 102 (21.3%) patients in high IATI (≥0.42) group. The proportion of age ≥ 60 years old ( χ2=24.746, P<0.001), proportion of diabetes mellitus ( χ2=5.570, P=0.018), fasting blood glucose ( t=-2.145, P=0.032), LAM density ( t=-3.735, P<0.001), LAM index ( t=-7.072, P<0.001), and LAM area/skeletal muscle area ratio ( Z=-9.630, P<0.001) in high IATI group were all higher than those in low IATI group, while proportion of males ( χ2=11.116, P<0.001), serum albumin ( Z=2.708, P=0.007) and skeletal muscle density ( t=12.380, P<0.001) were lower than those in low IATI group. Kaplan-Meier survival analysis showed that the 3-years overall survival rate of low IATI group was significantly higher than that in high IATI group (Log-rank χ2=19.188, P<0.001). Multivariate Cox regression analysis showed that IATI<0.42 [<0.42/≥0.42, HR(95% CI): 0.50 (0.31-0.83), P=0.007] was an independent protective factor of all-cause mortality, and age ≥60 years old [ HR (95% CI): 2.61 (1.60-4.23), P<0.001], diabetes mellitus [ HR (95% CI): 1.71 (1.06-2.78), P=0.029] and high blood neutrophil/lymphocyte ratio [ HR (95% CI): 1.04 (1.00-1.07), P=0.049] were the independent risk factors of all-cause mortality in maintenance dialysis patients. Stepwise Cox regression analysis showed that IATI<0.42 was still an independent protective factor of all-cause mortality in maintenance dialysis patients [<0.42/≥0.42, HR (95% CI): 0.45 (0.27-0.76), P=0.003]. Multivariate logistic regression analysis showed that low skeletal muscle density [ OR (95% CI): 0.84 (0.81-0.88), P<0.001] and high serum triglyceride [ OR (95% CI): 1.39 (1.07-1.82), P=0.015] were the independent influencing factors of IATI≥0.42. Conclusion:IATI<0.42 of the first lumbar level is an independent protective factor of all-cause mortality in maintenance dialysis patients. Localized myosteatosis within high-quality skeletal muscle may reduce the risk of all-cause mortality in these patients.
RÉSUMÉ
ObjectiveTo explore the possible mechanism of Bushen Huoxue Formula （补肾活血方， BHF） in the treatment of Parkinson's disease （PD） from the the perspective of intestinal flora. MethodsSeventy-two male C57/BL6J mice were randomly divided into blank group， model group， Madopar group and low-， medium- and high-dose BHF groups， with 12 mice in each group. The mice in the blank group were intraperitoneally injected with 10 ml/kg of normal saline， and those in the other groups were intraperitoneally injected with 30 mg/kg of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine （MPTP） at a concentration of 3 mg/ml to induce PD mice model， both once a day for 7 consecutive days. After successful modeling， the low-， medium-， and high-dose BHF groups were given 7.5， 15， and 30 g/（kg·d） of BHF by gavage， respectively， while the Madopar group was given 112.5 mg/（kg ·d） of Domedopar tablets by gavage， and the blank group and the model group were given 15 ml/（kg·d） of distilled water， all once a day for 14 consecutive days. The rod climbing test， rotating rod test， grip strength test and weight-bearing swimming test were used to evaluate the behavioral indicators of mice. Western blotting was used to measure the protein expression levels of Toll-like receptor （TLR）/nuclear factor kappa B （NF-κB） pathway inflammatory factors in the mouse ileum， including Toll-like receptor 2 （TLR2）， Toll-like receptor 4 （TLR4）， NF-κB， tumor necrosis factor α （TNF-α）， interleukin 6 （IL-6）， and interleukin 17 （IL- 17）. 16S rRNA high-throughput sequencing was used to analyze changes in mouse intestinal flora. ResultsCompared to those in the blank group， the mice in the model group had longer bottoming time when climbing the pole， reduced grip strength， shortened rotary pole duration and swimming duration， and increased protein expression levels of TLR2， TLR4， NF-κB， TNF-α， and IL-6 in the ileal tissue （P＜0.01）. Compared to the model group， the Madopar group and the low-， medium- and high-dose BHF groups had shortened bottoming time of the climbing pole and increased grip strength； the Madopar group and the high-dose BHF group had prolonged rotary pole duration， and reduced protein expressions of TLR2， TLR4， NF-κB， TNF-α， IL-6， and IL-17 levels； and only the high-dose BHF group had prolonged swimming duration （P＜0.05 or P＜0.01）. Compared to those in the low-dose BHF group， the bottoming time of the climbing pole were shorter in the moderate- and high-dose groups （P＜0.05 or P＜0.01）， and the grip strength increased while the protein expression levels of TLR2， TLR4 and IL-17 decreased in the high-dose group （P＜0.05 or P＜0.01）. The intestinal flora results showed significant differences between the blank group and the model group in the Dominance index， Pielou_e index， Shannon index， and Simpson index （P＜0.05 or P＜0.01）. Compared to those of the model group， the Shannon index， Chao1 index， and Observed_otus index of the Madopar group， as well as the Chao1 index， Observed_otus index， Dominance index， Pielou_e index， Shannon index， and Simpson index of the high-dose BHF group all showed significantly statistical differences （P＜0.05 or P＜0.01）. At the phylum level， the relative abundance categories of bacterial phyla with statistically significant differences in each group included Proteobacteria， Bacteroidetes， and Firmicutes （P＜0.05 or P＜0.01）. At the genus level， the relative abundance categories of bacterial genera with statistically significant diffe-rences among each group included Muribaculaceae， Akkermansia， and Helicobacter pylori （P＜0.05 or P＜0.01）. ConclusionThe possible mechanism of BHF in treating PD may be to reconstruct the disordered intestinal flora structure and improve the inflammatory response.
