24 hours) PCI. Results Among 1013 patients enrolled in the SUNDAY registry, 438 (male 74.8%, unstable angina 94.1%) received PCI after CAG, 35 patients received PCI within 24 hours [(1.0?0.0) day, group I], and 403 after 24 hours [ (7.5 ? 7.3) days, group II] of hospitalization (P

Objective To elucidate the clinical characteristics and prognosis of non-ST segment elevation acute coronary syndrome (NSTE-ACS)patients with metabolic syndrome. Methods SUNDAY(The Strategies for UA/NSTEMI and Delay of AngioplastY Registry)study was a retrospective registry of 1 013 patients with unstable angina or NSTEMI from Jan 2000 through Dec 2002. In this analysis , we compared the clinical features and prognosis with patients with or without metabolic syndrome and studied the relation between the number of markers-the MS score and prognosis. Results There were 743 patients with complete data and 343 patients(46.2%)satisfied the definition of Chinese metabolic syndrome .The latter were younger [(59.66?9.67)age vs. (61.11?10.37)age,P=0.052], with higher BMI ,SBP, DBP, blood glucose and disordered blood-lipid(P0.05) and coronary angiographic alterations(left main artery and trivessel) (P=0.006). Conclusion There were prevenlence in NSTE-ACS patients with metabolize syndrome and the later were younger .As the MS score increased so did obesity, dyslipidemia ,blood pressure, fasting glucose. Similarly, an increasing MS score was significantly related to more severe coronary angiographic alterations and cardiac events.

Objective To compare the effect of palliative mitral valve surgeries and medication therapies for secondary non-ischemic mitral regurgitation. Methods The clinical data of patients with non-ischemic functional mitral regurgitation treated in our hospital between 2009 and 2019 were retrospectively analyzed. Patients with a left ventricular ejection fraction (LVEF)＜40% underwent a dobutamine stress test, and a positive result was determined when the LVEF improved by more than 15% compared to the baseline value. Positive patients were divided into a surgery group and a medication group. The surgery group underwent surgical mitral valve repair or replacement, while the medication group received simple medication treatment. Follow-up on survival and cardiac function status through outpatient or telephone visits every six months after surgery, and patients underwent cardiac ultrasound examination one year after surgery. The main research endpoint was a composite endpoint of all-cause death, heart failure readmission, and heart transplantation, and the differences in cardiac function and cardiac ultrasound parameters between the two groups were compared. Results Ultimately 41 patients were collected, including 28 males and 13 females with an average age of 55.5±11.1 years. Twenty-five patients were in the surgery group and sixteen patients in the medication group. The median follow-up time was 16 months, ranging 1-96 months. The occurrence of all-cause death in the surgery group was lower than that in the medication group (HR=0.124, 95%CI 0.024-0.641, P=0.034). The difference between the two groups was not statistically significant in the composite endpoint (HR=0.499, 95%CI 0.523-1.631, P=0.229). The New York Heart Association (NYHA) grade of the surgery group was better (NYHA Ⅰ-Ⅱ accounted for 68.0% in the surgury group and 18.8% in the medication group, P<0.01) as well as the grade of mitral valve regurgitation (87.5% of the patients in the medication group had moderate or above regurgitation at follow-up, while all the patients in the surgery group had moderate below regurgitation, P<0.01). There was no statistical difference in preoperative and follow-up changes in echocardiograph parameters between the two groups (P＞0.05). Conclusion For non-ischemic functional mitral regurgitation, if the cardiac systolic function is well reserved, mitral valve surgery can improve survival and quality of life compare to simple medication therapy.

Objective To investigate the efficacy of lateral decubitus intramedullary nailing for treatment of subtrochanteric fractures of the femur.Methods From January 2012 to December 2015,23 patients with simple femoral subtrochanteric fracture were treated at Department of Orthopedic Trauma,Changhai Hospital.They were 15 males and 8 females,aged from 19 to 77 years (average,48.3 years).According to the Seinsheimer classification,there were 6 cases of type ⅡB,8 cases of type ⅡC,6 cases of type Ⅲ A,and 3 cases of type ⅢB.Their injuries were caused by traffic accident in 10 cases,falling from a height in 5 cases,and sprain in 8 cases.All patients were treated by closed reduction and anterograde intrarnedullary nailing at lateral decubitus.Their operative time,bleeding volume,fluoroscopic frequency,fracture healing time,functional recovery and complications were recorded and analyzed.Results Their operative time ranged from 55 to 80 min,averaging 65.7 min;their bleeding volumes ranged from 240 to 420 mL,averaging 304.3 mL;their fluoroscopic frequency ranged from 30 to 60 times,averaging 42.7 times.This cohort was followed up for 12 to 28 months (average,17.9 months).Their fracture healing time ranged from 4 to 10 months,averaging 5.5 months.Nonunion occurred in one patient but was cured by secondary operation.The HSS evaluation at the final follow-ups showed 17 excellent cases and 6 good ones,yielding an excellent to good rate of 100％.All the wounds healed by the first intention.No infection,deep vein thrombosis or implant failure was observed.Conclusion As lateral decubitus intramedullary nailing can achieve satisfactory clinical efficacy for subtrochanteric fractures of the femur,the body position of lateral decubitus may be a good alternative.

Objective To explore the treatment methods and surgical techniques of the third ventricle tumor combined with hydrocephalus under neuroendoscope. Methods The clinical data and imaging findings of 4 patients with third ventricle tumor combined with hydrocephalus, treated with surgery under neuroendoscopy, were retrospectively analyzed; and related literatures were reviewed to conclude the surgical experiences and skills. Results Three of the 4 patients were performed surgery only by neuroendoscopy, and 1 by neuroendoscopic auxiliary microscope for the tumor complete resection. The clinical symptoms improved obviously after the surgery, and no significant complications and no dead case were noted.We followed up the 4 patients for 3-18 months; MRI showed that the tumor did not relapse and the hydrocephalus got improvement. Conclusion Endoscopic navigation can help to directly reach the locations of third ventricle tumor and decrease the unnecessary damage, which enjoys its advantages in tumor resection,relieving obstructive hydrocephalus and rebuilding the cerebrospinal fluid circulation, indicating that surgery under neuroendoscope is a safe, effective and minimally invasive method.

Epigenetic changes are potentially important for the ontogeny and progression of tumors but are not usually studied because of the complexity of analyzing transcript regulation resulting from epigenetic alterations. Prostate cancer (PCa) is characterized by variable clinical manifestations and frequently unpredictable outcomes. We performed an expression quantitative trait loci (eQTL) analysis to identify the genomic regions that regulate gene expression in PCa and identified a relationship between DNA methylation and clinical information. Using multi-level information published in The Cancer Genome Atlas, we performed eQTL-based analyses on DNA methylation and gene expression. To better interpret these data, we correlated loci and clinical indexes to identify the important loci for both PCa development and progression. Our data demonstrated that although only a small proportion of genes are regulated via DNA methylation in PCa, these genes are enriched in important cancer-related groups. In addition, single nucleotide polymorphism analysis identified the locations of CpG sites and genes within at-risk loci, including the 19q13.2-q13.43 and 16q22.2-q23.1 loci. Further, an epigenetic association study of clinical indexes detected risk loci and pyrosequencing for site validation. Although DNA methylation-regulated genes across PCa samples are a small proportion, the associated genes play important roles in PCa carcinogenesis.

OBJECTIVETo demonstrate the effect of early strategies and revascularization patterns on in-hospital major adverse cardiac events (MACE) in patients with non-ST-segment elevation acute coronary syndrome (ACS) at intermediate or high risk.

METHODS910 Patients with non-ST-segment elevation ACS at intermediate or high risk were divided into either early invasive (n = 237) or initially conservative (n = 673) group according to whether or when coronary angiography (CAG) was performed after admission ( 48 h) in order to demonstrate the impact of early strategies and revascularization patterns on in-hospital MACE events (death, new-onset myocardial infarction or repeat revascularization).

RESULTSCompared with those of the initially conservative group, patients in the early invasive group had a shorter hospital stay and increased rate of MACE (6.3% vs 2.5%, OR 0.384, 95% CI 0.188 - 0.781, P = 0.006) or new-onset myocardial infarction (4.6% vs 0.9%, OR 0.185, 95% CI 0.068 - 0.505, P = 0.001), which was partly due to increased procedures of revascularization (86.9% vs 67.5%, P < 0.001). No differences were found among in-hospital mortality or rate of repeat revascularization between the two groups. During subgroup analysis, patients receiving PCI in the early invasive or initially conservative group had comparable rates of new-onset myocardial infarction, repeat revascularization or MACE events, whereas patients receiving CABG in the early invasive group had a higher rate of new-onset myocardial infarctions than those in the initially conservative group (7.5% vs 1.8%, P = 0.027).

CONCLUSIONSAn early invasive strategy in patients with non-ST-segment elevation ACS had comparable in-hospital mortality and higher rate of in-hospital myocardial infarction compared with an initially conservative strategy, an early invasive strategy with PCI seems safe and feasible without increased risk of adverse clinical events. The impact of early CABG on in-hospital adverse events warrants further investigation.

BACKGROUND: Colorectal carcinogenesis and progression are related to the gut microbiota and the tumor immune microenvironment. Our previous clinical trial demonstrated that berberine (BBR) hydrochloride might reduce the recurrence and canceration of colorectal adenoma (CRA). The present study aimed to further explore the mechanism of BBR in preventing colorectal cancer (CRC). METHODS: We performed metagenomics sequencing on fecal specimens obtained from the BBR intervention trial, and the differential bacteria before and after medication were validated using quantitative polymerase chain reaction. We further performed ApcMin/+ animal intervention tests, RNA sequencing, flow cytometry, immunohistochemistry, and enzyme-linked immunosorbent assays. RESULTS: The abundance of fecal Veillonella parvula ( V . parvula ) decreased significantly after BBR administration ( P = 0.0016) and increased through the development from CRA to CRC. Patients with CRC with a higher V. parvula abundance had worse tumor staging and a higher lymph node metastasis rate. The intestinal immune pathway of Immunoglobulin A production was activated, and the expression of TNFSF13B (Tumor necrosis factor superfamily 13b, encoding B lymphocyte stimulator [BLyS]), the representative gene of this pathway, and the genes encoding its receptors (interleukin-10 and transforming growth factor beta) were significantly upregulated. Animal experiments revealed that V. parvula promoted colorectal carcinogenesis and increased BLyS levels, while BBR reversed this effect. CONCLUSION: BBR might inhibit V. parvula and further weaken the immunomodulatory effect of B cells induced by V. parvula , thereby blocking the development of colorectal tumors.

OBJECTIVE: To study whether tricalcium phosphate(TCP) wear particles cause injuries of periprosthetic osteocytes in the mouse calvaria, and to explain its molecular mechanism. METHODS: Thirty six-week(ICR)male mice were randomly divided into sham group, model (TCP) group and 3-methyladenine (3-MA) group. A murine calvarial model of osteolysis was established by 30 mg of TCP wear particles implantation over the periosteum around the middle suture of calvaria in mice. On the second postoperative day, the autophagy specific inhibitor 3-MA (1.0 mg/kg) was subcutaneously injected to the calvaria in the 3-MA-treated mice every other day. After 2 weeks, blood and the calvaria were obtained. Micro-CT was used to detect bone mineral density(BMD), bone volume fraction (BVF) and porosity number. HE staining and flow cytometry were performed to analyze the viability and apoptosis of periprosthetic osteocytes. The serum levels of dentin matrix protein 1(DMP-1) and sclerostin (SOST) were determined by ELISA. The proteins expressions of DMP-1, SOST, Beclin-1 and microtuble-associated protein 1 light chain 3 (LC-3) were detected by Western blot in the calvaria osteocytes. RESULTS: Compared with the sham group, the mice in the TCP group showed that a significant decrease in the viability of periprosthetic osteocytes, but obvious increases in number of osteocytes death and osteocytes apoptosis (<0.05), and in serum level and protein expression of SOST; significant decreases in serum level and protein expression of DMP-1 (<0.05), and remarkable up-regulation of autophagy-related factors beclin-1 and the conversion of LC3-Ⅱ from LC3-I in the calvaria osteocytes. Compared with TCP group, the mice in the 3-MA group showed that injuries of calvaria osteocytes were obviously aggravated, and osteocytes apoptosis was significantly increased (<0.05). CONCLUSIONS TCP wear particles can cause injuries of periprosthetic osteocytes via activation of apoptosis and autophagy, which promotes osteolysis around the prosthesis osteolysis and joint aseptic loosening.
