Objective To analyze the evaluation and influencing factors of healthy enterprises in Hubei Province from 2020 to 2023. Methods A total of 351 enterprises participated in the healthy enterprise evaluation in Hubei province were selected as the study subjects using the judgmental sampling method. The differences in evaluation results including scales, industry sector, and ownership type of the enterprises were compared. Results The median and the 25th and 75th percentiles [M (P₂₅, P₇₅)] of the evaluation score among the 351 enterprises was 869 (838, 941) points. The evaluation pass rate was 82.3%. The M(P₂₅, P₇₅) of scores for the management system, health environment, health management and services, health culture, and health outcome review were 183 (174, 192), 190 (181, 198), 340 (321, 376), 133 (122, 142), and 26 (24, 28) points, with the score percentage of 91.5%, 86.4%, 85.0%, 88.7%, and 86.7%, respectively. The deduction rate exceeded 50.0% in six items, which predominantly concentrated within the primary indicator of the health management and services, among the tertiary indicators. The result of multiple linear regression analysis revealed that smaller enterprises had significantly lower evaluation scores (P<0.05), and domestically funded enterprises scored significantly lower than those with investment from Hong Kong, Macao and Taiwan, or foreign investments (all P<0.05). Conclusion Health management and services represent a weak area in healthy enterprise development in Hubei Province. It was suggested to improve policy incentives and support for medium-, small- and micro-sized enterprises, and domestically funded enterprises, to enhance healthy enterprise development levels.

Objective To explore the effects of TRAF6 inhibition on autophagy,myocardial inflammation and cardiac function in septic mice.Methods Twenty-four male Kunming mice were randomly divided into 4 groups:sham,sham + C25-140(sham+C),cecal ligation and puncture(CLP),and cecal ligation and puncture+C25-140(CLP+C)group.Sham+C group and CLP+C group were intraperitoneally injected with C25-140 after operation.LVEF and LVFS were evaluated by ultrasound 24 hours after operation.Serum TNF-α and IL1-β were measured by ELISA.HE staining was used to evaluate myocardial inflammatory response.Autophagosomes and mitochondrial microstructure of cardiomyocytes were observed by transmission electron microscopy.TRAF6 mRNA in myocardial tissue was detected by qPCR.The expression of TRAF6,P62,Beclin-1 and LC3B protein was detected by W-B.The effect of C25-140 on myocardial injury in the septic mice was observed by inhibiting autophagy with 3-MA.Results Compared with the sham group,the levels of TRAF6 mRNA and TRAF6 in the myocardial tissue in the CLP group were significantly increased(P<0.05)and the serum TNF-α and IL1-β concentrations were signifi-cantly increased(P<0.05).Meanwhile,the myocardial tissue HE staining showed inflammatory cell infiltration and the LVEF and LVFS levels were significantly decreased in the CLP group(P<0.05).Compared with CLP group,the CLP+C group showed that the expression of TRAF6 mRNA and TRAF6 protein decreased(P<0.05),serum TNF-α and IL1-β decreased(P<0.05),myocardial histopathological myocardial inflammatory cell infiltration decreased,the LVEF and LVFS levels increased(P<0.05).Electron microscopy showed that the mitochondrial swelling decreased,autophagosomes increased,expression of Beclin-1 and LC3Ⅱ/Ⅰ increased,and P62 expression decreased(P<0.05).As compared with CLP+C group,the CLP+C+3-MA group showed that obvious inflamma-tory cell infiltration in the myocardial pathology and the LVEF and LVFS levels decreased after 3-MA inhibited autophagy(P<0.05).Conclusion Inhibition of TRAF6 can not only ameliorate myocardial inflammatory injury and cardiac dysfunction in septic mice,but promote the involvment of cardiomyocyte autophagy in provention from sepsis-induced myocardial injury.

With increasing age, more and more patients with posterior chamber intraocular lens (ICL) implantation are facing the threat of cataracts to their visual acuity.When examining the eyes of cataract patients after ICL surgery, attention should be paid to whether the density of corneal endothelial cells is greater than 2 000 cells/mm 2, the state of the anterior chamber angle, and whether there are fundus abnormalities such as retinal detachment and choroidal neovascularization.When conducting eye biometry measurement, attention should be paid to the measurement starting and ending lines of anterior chamber depth and lens thickness.If patients undergo ICL combined with corneal refractive surgery, they should be examined with two or more devices to obtain corneal refractive power according to the examination requirements after corneal laser vision correction.When selecting the type of intraocular lens, consideration should be given to the histological characteristics of high myopia.Compared to C- and L- loops, plate-haptic is relatively more stable in patients with high myopia accompanied by large capsules and larger diameters of continuous curvilinear capsulorhexis.Kane, Barrett Universal Ⅱ, Olsen, Hill-RBF formulas for calculating the refractive power of intraocular lenses are more accurate in people with long axial length.It is recommended to perform ICL removal simultaneously with phacoemulsification and intraocular lens implantation, preferably with a surgical incision greater than 2.6 mm.Femtosecond laser assisted cataract extraction surgery, although superior to traditional phacoemulsification in reducing corneal endothelial cell loss, reducing corneal edema, and high-quality capsulorhexis, can cause incomplete capsulorhexis and fragmentation due to the cavitation bubbles, manual adjustment of location, and the impact of lower vault.It is recommended to use it with caution.Ophthalmologists should fully understand and pay attention to the characteristics and difficulties of cataract surgery after ICL surgery, communicate fully with patients, and make personalized surgery to achieve better visual outcomes.

OBJECTIVE To investigate the damage effect and mechanisms of cyclophosphamide(CTX)and its active metabolite derivative 4-hydroperoxycyclophosphamide(4-HC)to human neuroblas-toma SH-SY5Y cells.METHODS SH-SY5Y cells were treated with CTX[0(cell control),0.01,0.1,1,5,10,20,40 and 80 mmol·L-1]and 4-HC[0(cell control),0.01,0.1,1,5,10,20,40 and 80 μmol·L-1]for 48 h.Cell confluence and morphology were observed by the IncuCyte ZOOM system.Cell viability was assessed by CCK-8 assay.Lactate dehydrogenase(LDH)release was measured by LDH assay kit.SH-SY5Y cells were treated with CTX(0,1,5,10 and 20 mmol·L-1)and 4-HC(0,1,5,10 and 20 μmol·L-1)for 48 h before cell proliferation was analyzed by 5-ethynyl-2′-deoxyuridine(EdU)staining assay.Immunofluorescence was employed to assess the levels of the DNA double-strand break marker γ-H2AX and to evaluate changes in mitochondrial membrane potential.SH-SY5Y cells were treated with CTX(0,1,5 and 10 mmol·L-1)and 4-HC(0,1,5 and 10 μmol·L-1)for 48 h,and the alterations in glycolysis and oxidative phosphorylation levels were analyzed using the Seahorse XFe96 Analyzer.RESULTS Compared with the cell control group,cell confluence and cell viability were significantly reduced in the CTX and 4-HC groups(P<0.01),and the half-maximal inhibitory concentrations(IC50)for CTX and 4-HC were 4.44 mmol·L-1 and 4.78 μmol·L-1,respectively.The release rate of LDH was signif-icantly increased while the percentage of EdU+cells was significantly reduced in the CTX and 4-HC groups(P<0.01).The percentage of γ-H2AX+cells was significantly increased and mitochondrial membrane potential significantly decreased in the CTX and 4-HC group(P<0.05).Treatment with CTX and 4-HC resulted in reduced levels of maximum glycolytic capacity,glycolytic reserve,maximal respi-ration,and ATP production(P<0.05).CONCLUSION CTX and 4-HC exert significant cytotoxic effects on SH-SY5Y cells by disrupting cell membrane structure,impeding cell proliferation,and reducing cell viability.The mechanisms underlying these effects may involve intracellular DNA damage,disturbance of energy metabolism and mitochondrial dysfunction.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To explore the application effect of continuous quality improvement based on trauma team activation model in emergency triage.Methods:This study is a historical controlled study. A total of 12 215 trauma patients receiving initial treatment in the Emergency Department of the First Affiliated Hospital with Nanjing Medical University from January 2020 to June 2021 were selected as the research objects by the convenience sampling method, and 3 896 trauma patients from January to June 2020 were enrolled as the baseline group, and 4 054 patients from July to December 2020 were enrolled as the phaseⅠ improvement group, and 4 265 patients from January to June 2021 were enrolled as the phaseⅡ improvement group. The baseline group adopted the one-tiered trauma team activation model, which was evaluated and decided by the first-visiting doctor. The phaseⅠ improvement group received the one-tiered trauma team activation model, which was evaluated and decided by pretest triage nurses. The stageⅡ improvement group conducted the two-tiered trauma team activation model, which was evaluated and decided by pretest triage nurses. The trauma team activation time, overtriage rate and undertriage rate were compared between the three groups.Results:The trauma team activation time of the phaseⅠ improvement group and phaseⅡ improvement group was shorter than that of the baseline group, and the difference was statistically significant ( P<0.05). The overtriage rate of the phaseⅡ improvement group was lower than that of the baseline group and the phaseⅠ improvement group, and the differences were statistically significant ( P<0.05). The underage rate of the three groups were <5%, and the differences were not statistically significant ( P>0.05) . Conclusions:The two-tiered activation of trauma team mode led by nurses can shorten the trauma team activation time, reduce the overtriage rate and undertriage rate, improve the quality of trauma team activation.

Objective     To investigate the influence of prior percutaneous coronary intervention (PCI) on the outcome of coronary artery bypass grafting (CABG). Methods     Clinical data of 5 216 patients from Jiangsu Province CABG registry who underwent primary isolated CABG from 2016 to 2019 were retrospectively analyzed. Patients were divided into a PCI group (n=673) and a non-PCI group (n=4 543) according to whether they had received PCI treatment. The PCI group included 491 males and 182 females, aged 62.6±8.2 years, and the non-PCI group included 3 335 males and 1 208 females, aged 63.7±8.7 years. Multivariable logistic regression and propensity score matching (PSM) were used to compare 30-day mortality, incidence of major complications and 1-year follow-up outcomes between the two groups. Results     Both in original cohort and matched cohort, there was no statistical difference in the 30-day mortality [14 (2.1%) vs. 77 (1.7%), P=0.579; 14 (2.1%) vs. 11 (1.6%), P=0.686], or the incidence of major complications (myocardial infarction, stroke, mechanical ventilation≥24 h, dialysis for new-onset renal failure, deep sternal wound infection and atrial fibrillation) (all P>0.05). The rate of reoperation for bleeding in the PCI group was higher than that in the non-PCI group [19 (2.8%) vs. 67 (1.5%), P=0.016; 19 (2.8%) vs. 7 (1.0%), P=0.029]. Both in original cohort and matched cohort, there was no statistical difference in 1-year survival rate between the two groups [613 (93.1%) vs. 4 225 (94.6%), P=0.119; 613 (93.1%) vs. 630 (95.2%), P=0.124], while the re-admission rate in the PCI group was significantly higher than that in the non-PCI group [32 (4.9%) vs. 113 (2.5%), P=0.001; 32 (4.9%) vs. 17 (2.6%), P=0.040]. Conclusion     This study shows that a history of PCI treatment does not significantly increase the perioperative mortality and major complications of CABG, but increases the rate of cardiogenic re-admission 1 year postoperatively.

We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.

To investigate the changes of myocardial glucose metabolism in rabbit cardiac arrest models and the effect of hydrogen intervention by 18F-fluroro-2-deoxyglucose (18F-FDG) positron emission tomography (PET) imaging.
 Methods: Fifteen male New Zealand white rabbits were randomly divided into a hydrogen group (n=6), a control group (n=6) and a sham group (n=3). Cardiac arrest (CA) was induced by intravenous injection of potassium chloride. Conventional cardiopulmonary resuscitation (CPR) was initiated after five-minutes CA. The hydrogen group and the control group were mechanically ventilated into mixed gas with 4% hydrogen+96% oxygen and pure oxygen, respectively, for 30 minutes after CPR. Rats in the sham group was performed the same surgical procedure and was injected adrenaline and potassium chloride but did not induce CA. The vital signs at basic state and 30 min after return of spontaneous circulation (ROSC) were recorded in each group. The parameters of CPR were recorded in two CA groups. Myocardial glucose metabolism was assessed by positron emission tomography (PET) at basic state, 2 h and 24 h after ROSC. The maximum standardized uptake value (SUVmax) of 18F-FDG was measured.
 Results: There were no significant differences in the basal body weight and vital signs among the three groups. There was no significant difference in the blood glucose level before PET examination. The 18F-FDG SUVmax in the sham group at three time points was not significantly changed. In the hydrogen group and the control group, the 18F-FDG SUVmax at 2 h after ROSC were significantly higher than the basic level (1.89±0.47 vs 3.47±1.24 and 1.90±0.36 vs 4.26±0.80, respectively). Compared with the control group, the 18F-FDG SUVmax in the hydrogen group was lower at the point at 2 h after ROSC. The 18F-FDG SUVmax in the 2 CA group were down to the basic level at 24 h after ROSC (hydrogen group 2.02±0.64, control group 2.07±0.61).
 Conclusion: Myocardial glucose metabolism in CA rabbits was increased significantly after ROSC, and hydrogen intervention can reduce the degree of glucose metabolism.
