Objective To compare the intraoperative blood loss, postoperative drainage and hidden blood loss (HBL) in lumbar posterior lumbar interbody fusion (PLIF) in patients with and without rheumatoid arthritis (RA), and analyze the relevant factors of HBL in RA patients. Methods Fifty patients with RA (RA group) and 73 patients without RA (NRA group) treated in the Heze Municipal Hospital from January 2014 to April 2019 were enrolled in this study. The basic information, RA information, operation and related blood loss indicators in the two groups were compared. The intraoperative blood loss, postoperative drainage and HBL were the main results. The secondary results were operation time, preoperative and postoperative hematocrit (Hct) and hemoglobin (Hb) and their variation values, cases of anemia before and after surgery, number of new anemia after surgery, autologous blood and allogeneic blood transfusion, etc. The correlation factors of HBL in RA group were analyzed by multi-linear regression model. Results Therlogeneic blood were independently correlated to HBL (β=0.363, -0.272, 0.210, 1.204, all P less then 0.05). Conclusions There is no difference in TBL, intraoperative blood loss, postoperative drainage and operation duration between the RA and NRA group, while HBL and the proportion of HBL in the TBL are higher in the RA group. The RA group has higher Steinbrocker rating, no DMRDs and more Hb changes.Objective To evaluate the effects of neuromuscular exercise therapy on joint stability of knee osteoarthritis (OA) patients. Methods One hundred and ten patients with knee OA were enrolled in this ongoing prospective cohort study at Arthritis Clinic and Research Center, Peking University People's Hospital from September 2017 to October 2018. GSK2193874 mouse The treatment consisted of six-week neuromuscular exercise therapy. The participants were followed up at 6 weeks and 3 months after the therapy. The stability of the joint was evaluated by the index of knee joint stability (IKJS), which was extracted by a novel knee-aiming task combined with the multiscale entropy (MSE) analysis of the complexity of the light spot trajectories. The secondary outcomes were pain on the visual analogue scale (VAS, 0-100), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), quality of life on the Euro-quality of life-5 Dimensional (EQ-5D) VAS form, 30-second chair stand test and 40-meter walk test. One-way repeated measures ANOVA analysis was applied to compare the outcomes at baseline and 6 weeks and 3 months. Pearson partial analysis was used to investigate the correlation between the IKJS and the Kellgren-Lawrence (K/L) rate, pain and knee function. Results Ninety-six participants ((65±8) years, 21 males, 75 females) completed 3-month follow-up. There was a significant improvement in IKJS at the 6-week visit compared with that at baseline (0.369, 95% confidence interval (CI) 0.241-0.496, P0.05). There was improvement in pain VAS, WOMAC, EQ-5D-VAS, 30-second chair stand test and 40-meter walk test at 6 weeks and 3 months (all P less then 0.05). Conclusion The neuromuscular exercise therapy is effective in improving the joint stability of the knee OA patients. However, the effect gradually diminished over time. In addition, neuromuscular exercise can help relieve pain, improve the function and quality of life in patients with knee OA.Objective To evaluate the long-term clinical outcomes after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) for ostial/shaft lesions in patients with unprotected left main coronary artery (ULMCA). Method A total of 271 patients with isolated ostial/midshaft lesions in unprotected left main coronary artery who received drug-eluting stents (DES) implantation between January 2003 and July 2009 in Beijing An Zhen Hospital were consecutively enrolled . The endpoints of the study were all-cause death, repeat revascularization, myocardial infarction (MI) and stroke. Cox regression was carried out to analyze the all-cause mortality. Meanwhile, multivariate logistic regression analysis was performed to determine the independent risk factors of all-cause death. Results The mean age of the patients was (62±10) years, and 201 of them (74.2%) were male. The median follow-up was 12.5 years (interquartile range 10.1-14.5 years). During the follow-up, 46 patients (17.0%) died, of whom 20 (7.4%) died of a cardiovascular cause. A total of 38 (14.0%) cases suffered a MI, and 15 (5.5%) cases suffered a stroke. Repeat revascularization was performed in 63 (23.2%) cases. Multivariate logistic regression analysis showed that age (HR=1.041, 95%CI 1.003-1.081, P=0.033), creatinine (HR=1.028, 95%CI1.014-1.042, P less then 0.001) and diabetes mellitus (HR=1.924,95%CI 1.053-3.514, P=0.033) were independent risk factors of all-cause death, whereas left ventricular ejection fraction (LVEF) (HR=0.972, 95%CI0.953-0.992, P=0.007) was a protective factor. Conclusions During a median follow-up of 12.5 years, the prognosis of PCI for left main ostium/shaft lesion was good. Age, creatinine and diabetes mellitus are independent risk factors of all-cause death.Objective To investigate the effect of remote ischemic preconditioning (RIPC) on contrast-induced acute kidney injury (CI-AKI) in patients with chronic total occlusion (CTO) after percutaneous coronary intervention (PCI). Methods A total of 282 patients undergoing PCI at Zhongda Hospital Affiliated to Southeast University between June 2017 and January 2019 were prospectively enrolled. The patients were randomly divided into RIPC group (n=142) and control group (n=140). CI-AKI was defined as an increase in level of cystatin C (CysC)≥10% above baseline at 24 h after contrast administration. Baseline characteristics and the incidence of CI-AKI were compared between the two groups. The multivariate logistic regression analysis was further used to analyze the independent risk factors of CI-AKI. Results There were no significant differences in age, gender, smoking, hypertension, diabetes, stroke and old myocardial infarction, coronary artery bypass graft surgery, previous PCI history and laboratory test indicators, target vessel and pathological characteristics of CTO lesions, contrast agent dosage, J-CTO (Multicenter CTO Registry in Japan) score, SYNTAX (Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery) score, PCI success rate and stent number between the two groups (P>0.
