Risk factors for adverse cardiac events within 30 postoperative days in aged patients with hip fracture / 中华创伤骨科杂志

Objective:To explore the risk factors for adverse cardiac events within 30 postoperative days in the aged patients with hip fracture.Methods:We retrospectively evaluated the clinical data of 1, 004 aged patients who had been admitted to Department of Orthopaedics, The 7th Medical Center, PLA General Hospital for hip fractures from January 2012 to December 2016. According to whether cardiac complications occurred within 30 days after operation, they were divided into 2 groups: a group with adverse cardiac events and a group free from adverse cardiac events. The 2 groups were compared in terms of age, gender, concomitant disease, timing of surgery, type of surgery and anesthesia mode. Multivariate Logistic regression analysis was used to determine the independent risk factors of adverse cardiac events 30 days after operation. In addition, the 2 groups were also compared in 30-day mortality, 1-year mortality, and total mortality postoperation.Results:Adverse cardiac events occurred in 45 patients (4.5%) within 30 days after operation. The multivariate Logistic regression analysis showed that advanced age ( OR=1.085, 95% CI: 1.033-1.139), chronic renal insufficiency ( OR=5.296, 95% CI: 2.172-12.910), cardiac insufficiency ( OR=2.938, 95% CI: 1.283-6.729), delayed operation ( OR=3.682, 95% CI: 1.110-12.220) were independent risk factors for cardiac adverse events 30 days after operation. The 30-day mortality, 1-year mortality, and total mortality postoperation were respectively 17.8% (8/45), 26.7% (12/45) and 46.7% (21/45) for the group with adverse cardiac events, and respectively 3.6% (35/959), 9.1% (87/959) and 28.5%(273/959) for the group free from adverse cardiac events, showing significant differences between the2 groups (all P<0.05). Conclusions:Advanced age, cardiac insufficiency, chronic renal insufficiency and delayed surgery may be independent risk factors for adverse cardiac events within 30 days after surgery in the elderly patients with hip fracture who show a significantly higher mortality than those free from adverse cardiac events.

Observation on therapeutic effects Yanshu compound radix sophore injection for treatment of patients with bone metastasis pain of lung cancer / 中国中西医结合急救杂志

Objective To observe the clinical effect of Yanshu compound radix sophore injection combined with radiotherapy in treatment of patients with bone metastases from lung cancer. Methods A total of 116 patients with bone metastases from lung cancer admitted to the Department of Radiation Oncology of Gansu Provincial Cancer Hospital from January 2014 to December 2018 were selected. The 58 patients were treated by using three-dimensional conformal radiotherapy (3D-CRT), zoledronic acid and oxycodone sustained-release tablets (control group); the others 58 patients were treated radix sphore injection on basis of control group (integrated Chinese and western medicine). The two groups were treated continuously for 10 days as 1 course of treatment, taking a rest for one week in the middle, then they took the second course of treatment; after the end of 2 courses, the therapeutic effects were evaluated in the two groups. The pain grading, Karnofsky functional status (KPS) score and myelosuppression were observed before and after treatment in two groups, respectively. Results The proportions of patients with painless and mild pain after treatment in the integrated Chinese and western medicine group were significantly lower than those in control group [painless: 22.41% (13/58) vs. 39.66% (23/58), mild pain: 10.35% (6/58) vs. 46.55% (27/58)], while the proportions of patients with moderate pain and severe pain in the integrated Chinese and western medicine group were significantly higher than those of the control group [moderate pain: 53.45(31/58) vs. 12.07% (7/58), severe pain: 13.79% (8/58) vs 1.72% (1/58), both P < 0.05]. After treatment, the proportion of patients with improved KPS score in integrated Chinese and western medicine group was significantly higher than that in control group [55.17% (32/58) vs. 36.21% (21/58), P < 0.05], and the proportion of patients with stable and decreased KPS score were less than that of control group [stable KPS score:18.97%(11/58) vs. 27.59%(16/58), decreased KPS score:25.86% (15/58) vs. 36.21% (21/58)]. The proportions of patients with blood cell count (WBC), hemoglobin (Hb) and platelet count (PLT) showing no myelosuppression (at the zero degree) after treatment in integrated Chinese and western medicine group were obviously higher than those in control group [WBC: 77.59% (45/58) vs. 36.21% (21/58), Hb: 77.59% (45/58) vs. 70.69% (41/58), PLT: 58.62% (34/58) vs. 32.76% (19/58), all P < 0.05]. Conclusion Yanshu compound radix sphore injection combined with radiotherapy can reudce bone metastasis pain, reduce bone marrow suppression and improve quality of life in patients with advanced lung cancer and bone metastasis.

Molecular adsorbent recirculating system in treatment of severe pneumonia complicated with multipie organ dysfunction syndrome / 中华临床感染病杂志

Objective To evaluate the effect of molecular adsorbent recirculating system(MARS)in treatment of severe pneumonia complicated with multiple organ dysfunction syndrome(MODS).MethodsSeventy-five patients who were diagnosed as severe pneumonia complicated with MODS were randomly divided into MARS group,continuous renal replacement therapy(CRRT)group and routine comprehensive therapy group.Flow dynamics,respiration function,liver function and renal function,coagulation function,inflammatory mediators,and Marshall scores were measured and compared before and after the treatment. The survival curves in 60 days were also compared among three groups.Results With MARS therapy,mean heart rates,peak inspiratory airway pressure,serum TBil,plasma D-dimmer levels and Marshall score were decreased;mean artery pressure,PaO2,oxygenation index,urine output,and platelet counts were increased;the levels of proinflammatory(NO,IL-6,IL-8,TNF-α and LBP)and anti-inflammatory(IL-10 and IL-13)mediator were decreased remarkably.The differences of these indicators between MARS group and other two groups were statistically significant(P＜0.05).And after MARS therapy,respiratory rate and Cr level were decreased,while SaO2 and WBC were increased significantly(P＜0.05).The 60 day-survival rate in MARS group was 80%(20/25),36%(9/25)in routine comprehensive therapy,and 52%(13/ 25)in CRRT group(P＜0.05).Conclusion MARS therapy has better effect on severe pneumonia conplicated with MODS than routine comprehensive therapy and CRRT.

Open reduction,bone autografting and calcaneus reconstruction internal fixatin of intra-articular fractures of the calcaneus / 中国矫形外科杂志

[Objective] To evaluate the results of open reduction with bone autografting and calcaneus reconstruction with internal fixation in treatment of intra-articular calcaneus fracture. [Methods]From January 2005 to May 2007, 17 cases/19 feet of intra-articular calcaneus fractures received treatment of reconstruction plate and bone autografting, with 15 male/18 feet, 2 female/ 2 feet. Patients’ age ranged from 19 to 67 years (mean, 37.5 years). Fracture occurred in left side in 9 cases, right in 6 cases, both sides in 2 cases. All patients received treatment of open reduction with bone autografting and calcaneus reconstruction with internal fixation.[Results]All the patients achieved bone union. One stage union was achieved in 15 feet. Poor blood-supply was found in 3 feet and bone union was achieved after systematic treatment. Wound exudation was found in 1 feet, and bone union was achieved after dressing change treatment. All patients were followed up for an average of 19.7 months (10-38 months). The average union time was 2.5 months, without infection found.X-ray and CT were used to measure Bhler angle, width and axial length, all the indexed showed significant difference (P
