Objective To study the economic burden caused by healthcare-associated infection(HAI)in patients with hemorrhagic stroke.Methods Patients with hemorrhagic stroke in a tertiary first-class hospital from January 1,2021 to December 31,2022 were surveyed retrospectively.Data on demographic characteristics,clinical informa-tion,and hospitalization expenses were collected.According to the occurrence of HAI,patients were divided into the HAI group and control group.The length of hospital stay,increase in hospitalization expense,and hospital eco-nomic burden of the HAI group and control group were studied by propensity score matching(PSM)method and generalized linear model method.Results A total of 688 patients were included in the study,with 266 cases experi-encing HAI and a HAI incidence of 38.66％.After propensity score matching,199 patients in the HAI group were successfully matched.Compared with the control group,the median length of hospital stay in the HAI group doub-led,increasing by 16 days(Z=11.779,P＜0.001);the median hospitalization expense increased by 34 597.42 Yuan,with an increase of 85％(Z=6.299,P＜0.001).Based on the generalized linear model method,length of hospital days attributed to HAI increased by 1.24 times,hospitalization expense increased by 76％(both P＜0.001).Except surgical expenses,the HAI group had higher single medical expenses than the control group(all P＜0.05).Economic burden to hospital caused by HAI was 541 900 Yuan.Conclusion HAI significantly increases the economic burden of hemorrhagic stroke patients and hospitals,and prolongs the length of hospital stay.Clinical staff should enhance the awareness on infection control,reduce the incidence of HAI,and save medical resources.

BACKGROUND:The landing error scoring system test is a standard for assessing the risk of non-contact injuries and has not yet been developed for Chinese college soccer programs. OBJECTIVE:To establish a test evaluation standard for the landing error scoring system to provide a basis for evaluating the risk of non-contact injuries in college soccer students. METHODS:A prospective cohort study was designed in which 219 athletes from 10 college soccer teams were tested with the standard landing error scoring system,and the subjects were followed up by questionnaires and medical examinations for non-contact injuries of the lower extremities and trunk for 1 year after testing to determine sex differences and assessment criteria for the landing error scoring system test indicators. RESULTS AND CONCLUSION:The total score of the landing error scoring system was(8.22±1.65)points for 219 subjects,(8.29±1.74)for males and(8.07±1.44)for females,with no significant difference between males and females(P>0.05).Within 1 year after the test,the overall injury rate of 219 subjects was 10.05%and the morbidity rate was 15.98%;the injury rate of male subjects with non-contact injury of the lower limbs and trunk was 12.75%and the morbidity rate was 20.13%;the injury rate of female subjects with non-contact injury of the lower limbs and trunk was 4.29%and the morbidity rate was 7.14%.There were no significant differences in the injury rate between men and women(P<0.05).The total score of the landing error scoring system was higher in the injury group than in the non-injury group[(9.50±1.14)vs.(8.08±1.64),P<0.01];for male subjects,the total score of the landing error scoring system was higher in the injury group than in the non-injury group[(9.63±1.12)vs.(8.09±1.73),P<0.01].The area under the curve for the total score of the landing error scoring system was 0.773(P=0.000),which had a diagnostic value for the risk of non-contact injury of the lower extremities and trunk in male subjects,with a best cut-off point of 8.5,sensitivity of 0.842,specificity of 0.623,positive likelihood ratio of 2.233,negative likelihood ratio of 0.254,relative risk factor of 8.400,and odds ratio of 8.816;the total score of the landing error scoring system was not applicable for assessing the risk of non-contact injury of the lower extremities and trunk in female subjects.To conclude,the landing error scoring system test can be used as a criterion to assess the risk of non-contact injury to the lower extremity and trunk in Chinese college male soccer players,with an optimal cut-off point of 8.5.The risk of non-contact injury to the lower extremity and trunk is 8.40 times higher in male athletes with a landing error scoring system test score of≥8.5 than in male athletes with a score of<8.5.

Purpose::To assess the value of the driving pressure variation rate (ΔP%) in predicting the outcome of weaning from invasive mechanical ventilation in patients with acute respiratory distress syndrome.Methods::In this case-control study, a total of 35 patients with moderate-severe acute respiratory distress syndrome were admitted to the intensive care unit between January 2022 and December 2022 and received invasive mechanical ventilation for at least 48 h were enrolled. Patients were divided into successful weaning group and failed weaning group depending on whether they could be removed from ventilator support within 14 days. Outcome measures including driving pressure, PaO 2:FiO 2, and positive end-expiratory pressure, etc. were assessed every 24 h from day 0 to day 14 until successful weaning was achieved. The measurement data of non-normal distribution were presented as median (Q 1, Q 3), and the differences between groups were compared by Wilcoxon rank sum test. And categorical data use the Chi-square test or Fisher's exact test to compare. The predictive value of ΔP% in predicting the outcome of weaning from the ventilator was analyzed using receiver operating characteristic curves. Results::Of the total 35 patients included in the study, 17 were successful vs. 18 failed in weaning from a ventilator after 14 days of mechanical ventilation. The cut-off values of the median ΔP% measured by Operator 1 vs. Operator 2 in the first 4 days were ≥ 4.17% and 4.55%, respectively ( p < 0.001), with the area under curve of 0.804 (sensitivity of 88.2%, specificity of 64.7%) and 0.770 (sensitivity of 88.2%, specificity of 64.7%), respectively. There was a significant difference in mechanical ventilation duration between the successful weaning group and the failure weaning group (8 (6, 13) vs. 12 (7.5, 17.3), p = 0.043). The incidence of ventilator-associated pneumonia in the successful weaning group was significantly lower than in the failed weaning group (0.2‰ vs. 2.3‰, p = 0.001). There was a significant difference noted between these 2 groups in the 28-day mortality (11.8% vs. 66.7%, p = 0.003). Conclusion::The median ΔP% in the first 4 days of mechanical ventilation showed good predictive performance in predicting the outcome of weaning from mechanical ventilation within 14 days. Further study is needed to confirm this finding.

Lateral epicondylitis is a common clinical disease with characteristics of lateral elbow pain, insidious onset and easy recurrence, which can cause forearm pain and decreased wrist strength, seriously affecting patients′ daily life and work. Although there are various treatment methods for lateral epicondylitis with different effects, standard treatments are still lacking nowadays. Platelet-rich plasma (PRP) has good effects on bone and tendon repair, and is now widely used in the treatment of lateral epicondylitis. However, there is a lack of a unified understanding of the technology and specifications of PRP in the treatment of lateral epicondylitis. Therefore, the Sports Medicine Branch of the Chinese Medical Association and Physical Medicine and Rehabilitation Branch of the Chinese Medical Association organized experts in the fields of sports medicine and rehabilitation medicine in China to formulate the "clinical expert consensus on platelet-rich plasma treatment for lateral epicondylitis (2022 version)", and proposed suggestions based on evidence-based medicine mainly from the concept, epidemiology and pathophysiology of lateral epicondylitis, symptoms, signs and imaging manifestations of lateral epicondylitis, PRP concept and application component requirements, quality control of PRP preparation technology, indications and contraindications of PRP in the treatment of lateral epicondylitis, PRP injection in the treatment of lateral epicondylitis, application of PRP in the operation of lateral epicondylitis, related problems after PRP treatment of lateral epicondylitis, evaluation of the results after PRP treatment of lateral epicondylitis, and health and economic evaluation of PRP treatment of lateral epicondylitis, so as to provide guidance for clinical diagnosis and treatment.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.

During the epidemic of emerging respiratory infectious disease, a large number of medical resources around the world were involved to the prevention and control for it. The prevention and control for TB in many countries was affected, such as stagnating or even regressing. On the other hand, because some common prevention and control measures, it may also reduce the spread of TB in a certain extent. Through reviewing the negative effects of emerging respiratory infectious disease on TB prevention and control, such as the decline in the number of tests and reports, the reduction of providers. Of course, there are also positive effects, such as the improvement of service capabilities, citizens' health literacy, and government's emergency management. By summarizing the experience and region cases, the paper listed some references to promote the achievement of ^“End TB Strategy^” by 2035. Under the new opportunities, the prevention and control for TB can face new development.

Objective: To compare the long-term prognosis of fulminant myocarditis (FM) and non-fulminant myocarditis (NFM) patients who survived and discharged from hospital, and to explore the factors associated with the long-term prognosis and impaired cardiac function. Methods: This study was a retrospective study. Consecutive patients with acute myocarditis hospitalized in Tongji Hospital from January 2017 to December 2020 were enrolled and divided into FM group and NFM group according to the type of myocarditis. Then, patients in the FM group were further divided into normal cardiac function group and impaired cardiac function group according the left ventricular ejection fraction (LVEF). All patients with acute myocarditis were treated with antiviral, immunomodulatory, immunosuppressive medications and symptomatic and supportive treatment, while FM patients were treated with comprehensive treatment plan. Clinical data at admission of enrolled patients were collected through the electronic medical record system. Patients were clinically followed-up at 1, 3, 6 and 12 months, then once a year after discharge by clinical visit. The primary endpoints included major cardiovascular events, impaired cardiac function was defined by LVEF<55%. Kaplan-Meier survival curve was used to analyze the occurrence of LVEF<55% and left ventricular enlargement during the follow-up of patients in FM group and NFM group, and Log-rank test was used for comparison between groups. Cox regression model was used to analyze the risk factors of impaired cardiac function in patients with FM during follow-up. Results: A total of 125 patients with acute myocarditis were enrolled (66 in FM group and 59 in NFM group). Compared with NFM group, the proportion of FM patients with the lowest LVEF<55% during hospitalization was higher (P<0.01), and the recovery time of normal LVEF during hospitalization was longer (P<0.01). The proportion of LVEF<55% at discharge was similar between the two groups (P=0.071). During the follow-up of 12 (6, 24) months, 1 patient (1.5%) died due to cardiac reasons in FM group after discharge, 16 patients (24.2%) had sustained LVEF<55% after discharge, and 8 patients (12.1%) had left ventricular enlargement. In NFM group, 3 patients (5.1%) had sustained LVEF<55%, and 1 patient (1.7%) had left ventricular enlargement. Kaplan-Meier survival curve analysis showed that the incidence of sustained LVEF<55% in FM group was higher than that in NFM group (P=0.003), and the incidence of left ventricular enlargement was also higher than that in NFM group (P=0.024). Subgroup analysis of patients in the FM group showed that, compared with the normal cardiac function group, the time from onset to admission was shorter (P=0.011), the proportion of LVEF<55% at discharge was higher (P=0.039), the proportion of coronary angiography was higher (P=0.014), and the LVEF recovery time during hospitalization was longer (P=0.036) in FM patients with impaired cardiac function. Multivariate Cox regression analysis showed that longer LVEF recovery time during hospitalization was an independent risk factor for cardiac function impairment after discharge of FM patients (HR=1.199, 95%CI 1.023-1.406, P=0.025). Conclusions: The incidence of reduced LVEF is significantly higher in FM patients than that in NFM patients. Longer LVEF recovery time during hospitalization is an independent risk factor for cardiac function impairment in FM patients after discharge.

OBJECTIVE: To observe the effect of moxibustion at oppositely-located points "Mingmen" (GV 4) and "Shenque" (CV 8) on the motor function of the hind limbs and bladder function in rats with neurogenic bladder after suprasacral spinal cord injury (SCI), so as to explore the effect of this therapy on bladder tissue apoptosis mediated by endoplasmic reticulum stress pathway. METHODS: Twenty-eight female Wistar rats were randomly divided into a sham-operation group (8 rats) and a model establishment group (20 rats). Using the modified Allen's method, the spinal cord of T₁₀ segment was injured to establish a neurogenic bladder model in the model establishment group. Sixteen rats were modeled successfully and then divided into a model group (8 rats) and a moxibustion group (8 rats). In the moxibustion group, 2 h after consciousness regaining from modeling anesthesia, moxibustion was exerted at "Shenque" (CV 8) and "Mingmen" (GV 4), 2 cones at each acupoint in one intervention. The intervention was administered once every two days and 5-time intervention was required totally. After intervention, Basso, Beattie and Bresnahan locomotor rating scale (BBB) score for the motor function of the hind limbs, and the urodynamics indexes (maximum bladder capacity, urine leakage pressure and bladder compliance) were compared among groups. HE staining method was adopted to observe the morphological changes of bladder tissue. With Western blot method and real-time PCR assay, the protein and mRNA expressions of the endoplasmic reticulum stress-related genes (glucose- regulated protein 78 [GRP78], activating transcription factor 4 [ATF4] and cysteinyl aspartate specific proteinase-12 [Caspase-12]) were determined. RESULTS: The transitional epithelial cells were arranged irregularly, the bladder wall was getting thinner, and the cellular vacuolar degeneration and neutrophil infiltration were found in the model group. Whereas, compared with the model group, in the moxibustion group, the arrangement of transitional epithelial cells was clear and continuous in layers, the cellular vacuolar degeneration was mild and the infiltration presented in a small amount of neutrophil granulocytes. Compared with the sham-operation group, in the model group, the BBB score was reduced (P<0.01), the maximum bladder capacity and bladder compliance were increased (P<0.01), and the protein expression levels of GRP78, ATF4 and Caspase-12, as well as mRNA expressions were all increased (P<0.01). In comparison with the model group, in the moxibustion group, BBB score was increased (P<0.01), the maximum bladder capacity and bladder compliance were decreased (P<0.01), and the protein and mRNA expression levels of GRP78, ATF4 and Caspase-12 were all decreased (P<0.01). CONCLUSION Moxibustion at the "oppositely-located points" improves the urination function, alleviate urine retention in neurogenic bladder rats after spinal cord injury. The underlying mechanism may be related to the down-regulation of the expressions of GRP78, ATF4 and Caspase-12 in the endoplasmic reticulum stress pathway of the bladder tissues, and thus to alleviate the apoptosis of bladder tissue.

OBJECTIVE: To explore the risk factors of hidden blood loss in osteoporosis vertebral compression fractures during percutaneous vertebral augmentation. METHODS: From October 2018 to December 2019, 360 patients with osteoporosis vertebral compression fractures who received percutaneous vertebral augmentation were enrolled in this study. The factors analyzed included gender, age, surgical methods, disease course, height, weight, the operative segment, bone mineral density, amount of bone cement, operative time, percentage of height loss, percentage of vertebral height restoration, cement leakage, blood clotting function, preoperative and postoperative hemoglobin and hematocrit and other internal diseases. Total blood loss was calculated by Gross's formula, influential factors of the hidden blood loss were further analyzed by t-test, multivariate linear regression and one-way ANOVA analysis. RESULTS: Surgical methods, the operative segment, disease course, cement leakage, preoperative hemoglobin, cement leakage via the basivertebral and segmental vein were significantly correlated with hidden blood loss(P<0.05). CONCLUSION Patients with percutaneous kyphoplasty, two-level and multi-level surgery, the course of the disease beyond 6 weeks, cement leakage via the basivertebral and segmental vein, and lower preoperative hemoglobin had more perioperative hidden blood loss.

Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.
