Objective: To compare the 5-year follow-up outcomes of radiofrequency catheter ablation (RFCA) combined with left atrial appendage closure (LAAC) and long-term oral anticoagulant (OAC) after RFCA in patients with atrial fibrillation. Methods: This retrospective cross-sectional study included patients with atrial fibrillation who underwent"one-stop"procedure in the First Affiliated Hospital of Ningbo University from September 2015 to December 2017 (RFCA+LAAC group). Baseline data of patients were collected. Propensity score matching at the ratio of 1∶1 was used to select patients with atrial fibrillation who took long-term OAC after RFCA (RFCA+OAC group). The maintenance rate of sinus rhythm and the incidence of adverse events during follow-up were compared between the two groups. Results: A total of 110 patients were enrolled in the RFCA+LAAC group and RFCA+OAC group, respectively. Age of patients was (67.4±8.8) years in RFCA+LAAC group, and there were 42 (38.2%) female patients. Age of patients was (67.3±7.9) years in RFCA+OAC group, and there were 47 (42.7%) female patients. The patients were followed up for mean of (5.3±1.1) years. There was no significant difference in the maintenance rate of sinus rhythm (log-rank: χ²=0.277, P=0.602) and incidence of ischemic stroke events (2.7% (3/110) vs. 4.5% (5/110), P=0.719) during follow-up between the two groups. The incidence of bleeding events (6.4% (7/110) vs. 18.2% (20/110), P=0.008) and major bleeding events (1.8% (2/110) vs. 8.2% (9/110), P=0.030) was significantly higher in the RFCA+OAC group than in the RFCA+LAAC group. Conclusion: There is no significant difference between RFCA+LAAC group and RFCA+OAC group in maintenance rate of sinus rhythm and incidence of ischemic stroke events. Patients in the RFCA+LAAC group have a lower risk of bleeding events compared to the RFCA+OAC group.

Objective: To analyze the mortality level and tendency of road traffic injury in Shandong province from 2012 to 2020. Methods: Based on the data of road traffic deaths from the cause of death registration system in Shandong province from 2012 to 2020, the mortality rates of road traffic injury were calculated by sex, age, area, and injury type. The mortality was standardized based on the age structure of the Chinese population in the sixth Population Census in 2010. The annual percent change (APC) and average annual percent change (AAPC) of the mortalities and the standarized mortalities were calculated by using Joinpoint regression model, and the trends were also examined. Results: In 2020, the crude mortality of road traffic injury in Shandong Province was 15.58/100 000, and the standardized mortality was 12.90/100 000. From 2012 to 2020, the standardized mortality of road traffic injury in Shandong province showed a downward trend with AAPC of -5.4%. The standardized mortality of middle-south mountain areas, male and children aged 0-14 years in Shandong showed a significantly decreasing trend with AAPC of -6.8%, -6.1% and -6.0%, respectively. The standardized mortality of people aged 65 years and over did not decrease significantly, but the number of deaths increased significantly by 50.96% in 2020 (5 780 cases), compared with those in 2012 (3 829 cases). The standardized mortality of pedestrian and motorcyclists decreased significantly with AAPC of -7.5% and -6.7%, respectively. There was no significant change in the standardized mortality among people who rode motor vehicles or bicycles. Conclusion: From 2012 to 2020, the standardized mortality of road traffic injury in Shandong Province showed an obvious downward trend, but the standardized mortality of people aged 65 years and over did not decrease significantly. In the future, it is still necessary to take government-led, multi-sectoral collaboration, with a focus on comprehensive preventive measures, to further reduce road traffic injury mortality.

Objective To understand the prevalence and risk factors of Blastocystis hominis infection in inpatients in Jiangjin District, Chongqing City. Methods A cross-sectional study was conducted in a community hospital in Jiangjin District, Chongqing City, and the inpatients were surveyed by questionnaires. After obtaining the informed consent from the inpatients or legal guardians, the stool and blood samples were collected and examined by microscopy and PCR from April 17 to May 1, 2018. The univariate analysis and logistic regression analysis were used to analyze the risk factors of the B. hominis infection. Results A total of 198 hospitalized patients were investigated, and the infection rate of B. hominis was 10.61% (21/198), and the infection rate of the females (12.10%) was higher than that of the males (8.11%), but the difference was not statistically significant. The highest rate of infection was 19.23% in the age group of 10 to 20 years, followed by 17.74% in the age group of 60 years and above, and the lowest rate was 2.38% in the age group of 20 to 40 years. The difference in infection rates of B. hominis among the different age groups was statistically significant (P < 0.05). The infection rate of B. hominis in the people who used dry pail latrines was 33.30%, which was higher than that of the people who used water flush toilets (9.10%) (P < 0.05). The genotypes of B. hominis were ST1, ST3, ST6 and ST7, and ST6 and ST3 being the most predominant genotypes which accounted for 47.62% (10/21) and 38.10% (8/21) respectively, and among the infected males, the genotypes were only ST3 and ST6. The multiple logistic regression analysis showed that among the factors affecting B. hominis infection, only keeping pets was a risk factor [OR = 3.798, 95% CI (1.245, 11.581), P < 0.05]. Conclusion A high prevalence of B. hominis infection is found in the inpatients in Jiangjin District, Chongqing City, the predominant genotypes are ST6 and ST3, and keeping pets may be one of the main risk factors.

Epimedii Folium,a commonly used traditional Chinese medicine,has the effect of tonifying kidney Yang,strengthening bones and treating rheumatism. However,in recent years,the number of reports on adverse reactions of Epimedii Folium and its Chinese patent medicines such as Xianling Gubao Capsules and Zhuanggu Guanjie Pills has been gradually increased,and the toxicity of Epimedii Folium has attracted more and more attention. In this article,the ancient and modern literature on Epimedii Folium was traced through a comprehensive and systematic literature analysis method. According to the 2015 edition of the Chinese Pharmacopoeia,Epimedii Folium refers to the dried leaves of Epimedii Folium brevicomu,E. sugittutum,E. pubescens or E. koreuuum. The Chinese Pharmacopoeia also includes E. wushanense of Wushan Epimedium,which is the same plant variety as Epimedium. The study showed that there were differences in the geographical distribution,composition and toxicity among five species of Epimedium. This paper also explained the toxicity mechanism as well as efficacy enhancing and toxicity reducing effects of Epimedii Folium,and reported its related adverse reaction cases. Through a retrospective comparative study on the toxicity of the modern Chinese patent medicines Xianling Gubao Capsules and Zhuanggu Guanjie Pills containing Epimedii Folium,it was believed that Epimedii Folium had cardiovascular system toxicity,neurotoxicity,hepatotoxicity,long-term toxicity,acute toxicity,genotoxicity and special toxicity; its safe medication factors included patient syndrome,doctor factors,drug factors,processing and compatibility factors. Meanwhile,strategies were proposed to improve patient safety medication awareness,standardize Epimedii Folium varieties and quality supervision,and the toxicity of Epimedii Folium was studied,hoping to draw attention from scholars to the safety of Epimedii Folium,improve the safe use of Epimedii Folium,and prevent adverse reactions.

Rectal neuroendocrine neoplasms (NENs) are low-grade malignancies, which are slow-growing and usually become symptomatic late in the course of the disease (Basuroy et al., 2016). In recent years, rectal NENs are increasingly frequently detected, with the widespread availability and accessibility of endoscopy and cross-sectional imaging modalities (Kos-Kudla et al., 2017). Multiple studies have shown that endoscopic ultrasound (EUS) is an advanced endoscopic technique and is currently used in the diagnosis and preoperative assessment of NENs (Kim, 2012; Liu et al., 2013; Zhang et al., 2017). However, EUS imaging of rectal NEN and differential diagnosis with other submucosal tumors (SMTs) has not been adequately reported. In this study, we reviewed and summarized the EUS imaging and pathological features of rectal NENs of 38 cases to improve preoperative diagnosis rate and reduce unreasonable treatment.

OBJECTIVE To investigate the neuroprotective effect and possible mechanisms of lute-olin-7-O-β-D-glucuronide (LGU) against focalcerebral ischemic injury. METHODS The focal cerebral ischemic injury model was established by middle cerebral artery occlusion (MCAO). Male Sprague Dawley rats were randomly divided into sham group,model group(MCAO),LGU group(0.24,0.72 and 2.16 mg·kg-1)and positive control group(Edaravone at 5 mg·kg-1).LGU was injected intravenously 30 min after MCAO.Neurological severity score,infarct volume and brain water content were detected 24 h after MCAO and the levels of Na+-K+ATPase,Ca2+ATPase,TNF-α and IL-1β were detected to explore the possible mechanisms.For the therapeutic time window test,LGU(0.72 mg·kg-1)was injected intrave-nously 0.5, 2, 4, 6, 8, 10 and 12 h respectively after MCAO. To evaluate motion behavior, LGU were injected intravenously 30 min after MCAO and once per day during detection period. The changes of motor coordination were detected by rotating rod method and grip strength analysis, and the changes of gaits were detected using DigiGait Imaging System. RESULTS LGU improved the neurological severity score, infarct volume ratio and brain water content. The therapeutic time window of LGU for cerebral infarction and brain edema was at least 6 h and for neurological dysfunction was 12 h.LGU also prolonged the latency on rotarod, increased the forelimb tension and improved 8 gait parameters, including stance duration,stride length,stance width,paw area,paw area variability,gait symmetry,ataxia coefficient and tau propulsion.Furthermore,LGU increased Na+-K+-ATPase and Ca2+-ATPase levels in the cortex and hippocampus in the ischemic side,reduced the levels of TNF-α and IL-1β in the serum. CONCLUSION LGU has a significant neuroprotective effect against cerebral ischemic injury via improving energy metabolism and reducing inflammation.

Objective: To explore influence of continuous thoracic paravertebral block(CTPVB)under ultrasound-guidance combined with general anesthesia on inflammatory reaction and homodynamic of patients who underwent thoracotomy.Methods: 138 patients who underwent thoracotomy were prospectively selected and were divided into observation group(69 cases)and control group(69 cases)as random number table.Patients of observation group received CTPVB under ultrasound-guidance combined with general anesthesia and that of control group received general anesthesia.The changes of IL-6,IL-10 and TNF-α postoperative 48h and postoperative VAS score between the two groups were compared.And the VAS scores postoperative 2h,12h,24h and 48h also were observed.Besides,the mean arterial pressure and heart rate between the two groups at various time point included tranquillization time(T0),the 15 min(T1)after CTPVB combined with general anesthesia,the time post induced intubation(T2),5 min post skin incision(T3)and the time pre extubation(T4)were compared and analyzed so as to research its influence on hemodynamic.Results: The IL-6 and TNF-α postoperative 48h of observation group were significantly lower than that of control group(t=15.95,t=46.99,P＜0.05).And postoperative IL-10 of observation group was significantly higher than that of control group(t=134.3,P＜0.05).And the VAS scores of observation group at postoperative 2h,12h,24h and 48h were significantly lower than that of control group(t=13.91,t=17.1,t=2.321,t=9.231,P＜0.05),respectively.Conclusion: CTPVB under ultrasound-guidance combined with general anesthesia can improve postoperatively analgesic effect for patients,and it don't affect patients' blood pressure and heart rate,and it can reduce inflammatory reaction of patients who underwent thoracotomy and promote rehabilitation of patients.

A 24-year-old male suffered from acute nephritic syndrome, liver dysfunction, and mesenteric mass. Laboratory examination showed a variety of autoantibodies (ANA, SM, and A-β2-GP1) were positive. The biopsies of the kidney and the mesenteric mass were performed. The diagnosis was typeⅤ + Ⅲ lupus nephritis accompanied with Castleman's disease. Then the patient was given induction therapy of glucocorticoids and cyclophosphamide for the first 3 months, followed by rituximab as maintenance therapy. The patient was followed up after 0, 3, and 9 months. After 3-month treatment, lupus nephritis was partially remitted, and systemic lupus erythematosus disease activity index (SLEDAI) decreased to 4 scores in an inactivity phase from 20 scores in a serious activity phase at baseline. Nine months later, lupus nephritis was completely remitted and 50％ mesenteric mass was regressed through CT scanning. Lupus nephritis can accompany with multicentric Castleman's disease. Due to lack of clinical specificity and effective therapy, patients may have a high misdiagnosis rate and poor prognosis. The most reliable way to establish a definitive diagnosis relays on histopathologic confirmation. The management of induction therapy of glucocorticoids and cyclophosphamide, followed maintenance therapy of rituximab may become a beneficial treatment.

OBJECTIVES: To observe the changes of cystathionine β-synthase （CBS） expression in the cerebral cortex after brain contusion at different times. METHODS: An experimental model of traumatic brain injury （TBI） in mice was established by an improved weight-drop device. Then Western blotting and immunohistochemical examination were used to detect the CBS expression in cerebral cortex around injury at different time points （1 h, 6 h, 12 h, 1 d, 2 d, 3 d, 7 d）. RESULTS: The results of Western blotting revealed that the expression level of CBS was down-regulated and reached its lowest level at the 3rd days after injury, and then restored to normal level after 7 days. The results of immunohistochemistry showed that CBS was present in the normal brain cortex. CBS expression gradually decreased at the 3rd days after injury, and then restored to normal level after 7 days. CONCLUSIONS CBS has the potential to be a reference index for time estimation after brain contusion in forensic practice.
