ObjectiveTo explore the effect of different doses of low molecular weight heparin (LMWH) on the patency rate of cuffed central venous catheter used by patients for hemodialysis therapy.MethodsFrom June 2012 to January 2018, patients who received long-term hemodialysis in 363 Hospital with cuffed central venous catheter were enrolled in this retrospective study. According to the dose of LMWH used in hemodialysis, they were divided into below 60 U/kg group and greater than or equal to 60 U/kg group. The general parameters, frequency of urokinase use, bleeding events, severe coagulation in dialysis line and occurrence of catheter dysfunction were collected and compared between two groups.ResultsA total of 48 cases were enrolled. Of these, the doses of LMWH of 31 cases were below 60 U/kg and 17 cases were greater than or equal to 60 U/kg. There was no significant difference between the two groups in terms of age, sex, diabetes, hemoglobin, platelets, albumin, low-density lipoprotein cholesterol, or hypersensitive C-reactive protein parameters (P>0.05). Between the below 60 U/kg group and the greater than or equal to 60 U/kg group, there was no statistically significant difference in the incidence of catheter dysfunction (16.1% vs. 29.4%; χ2=0.507, P=0.476) or the incidence of bleeding events (1.77 vs. 2.81 times per 1 000 catheter-days; χ2=1.500, P=0.221). The frequency of urokinase used in the two group were 27.89 and 36.18 times per 1 000 catheter-days, respectively (χ2=5.927, P=0.015) and the frequency of severe coagulation were 6.88 and 2.30 times per 1 000 catheter-days, respectively (χ2=5.140, P=0.023). The differences were statistically significant.ConclusionThe lower dose of LMWH used in hemodialysis for preventing extra-corporeal circuit thrombosis does not result in the decrease of the patency rate of cuffed central venous catheter.
【摘要】 目的 探讨新诊断的多发性肌炎（PM）、皮肌炎（DM）和无肌病性皮肌炎（ADM）肺部病变发生率、临床特点及相关因素。 方法 回顾性分析2008年1月—2010年7月新确诊的206例PM、DM、ADM临床表现、肺部影像学、肺功能、超声心动图和实验室指标。 结果 206例患者中合并肺部病变156例，以肺间质病变（ILD）最多见，占患者总数的51.46%。在性别、病程、是否吸烟方面合并ILD与无ILD患者相比差异无统计学意义，合并ILD患者年龄大于无ILD组。合并ILD患者呼吸困难、发热、雷诺现象、关节炎或关节痛概率增加。合并ILD组白蛋白低于无ILD组，血沉和免疫球蛋白IgM高于无ILD组。急性ILD组中女性患者及出现雷诺现象的概率高于慢性组。206例患者中死亡13例，其中周围型肺癌1例，特发性血小板减少并颅内出血1例，严重肺部感染11例；死亡患者中10例伴肺间质纤维化。合并急性ILD患者死亡率较慢性组高2倍。 结论 PM、DM、ADM患者肺部病变发生率高，以ILD多见，发热、年龄大、白蛋白降低、血沉升高、雷诺现象及关节炎或关节痛都是合并ILD的相关因素。合并急性ILD患者预后差，死亡者常合并肺部感染。【Abstract】 Objective To explore the prevalence, clinical features, and predictive factors of pulmonary involvement in newly diagnosed polymyositis (PM), dermatomyositis (DM) and amyopathic dermatomyositis (ADM), in order to carry out early diagnosis and treatment, and improve the prognosis. Methods The clinical manifestations, chest imaging, pulmonary function test, ultrasonic cardiography and laboratory results of 206 inpatients with PM, DM and ADM in West China Hospital of Sichuan University from January 2008 to July 2010 were reviewed retrospectively. Results One hundred and fifty-six out of 206 patients developed PM/DM/ADM associated lung diseases, including 106 cases (51.46%) of interstitial lung disease (ILD). There was no significant difference in gender, disease duration, and smoking or not between the ILD and non-ILD group, but patients in the ILD group were significantly older than non-ILD group. The results also showed that patients with ILD were much more likely to have symptoms of breathing difficulties, fever, Raynaud phenomenon and arthritis/arthralgia. The patients with ILD had lower level of albumin but higher levels of ESR and IgM; In the group of acute ILD, female patients and the ratio of Raynaud phenomenon were higher than those in the chronicity group. Of the 206 patients, 13 patients died, including 1 death of peripheral lung cancer, 1 of essential thrombocytopenia and intracranial hemorrhages, and 11 of severe lung infection, and 10 in these patients developed ILD. Mortality in patients with acute ILD was 2 times higher than the chronicity group. Conclusion The prevalence of lung diseases is high in patients with PM, DM and ADM. ILD is the main pulmonary involvement, and fever, older age at onset, hypoalbuminemia, higher values of blood sedimentation, Raynaud phenomenon and arthritis or arthralgia were the predictive factors for developing ILD. Patients with acute ILD have poor prognosis. Death cases often have pulmonary infections.
Objective To explore the relationship between preoperative fasting plasma glucose (FPG) and postoperative pulmonary complications (PPCs) in type 2 diabetic patients undergoing elective thoracoscopic lung resection, and provide a reference for prediction and prevention of PPCs in the clinic. Methods A retrospective analysis was performed on the type 2 diabetic patients who underwent elective thoracoscopic lung resection for the first time in our hospital from January 2017 to March 2021. According to the level of FPG one day before the operation, the patients were divided into three groups: a hypoglycemia group (<6.1 mmol/L), a medium level blood glucose group (≥6.1 mmol/L and <8.0 mmol/L) and a high blood glucose group (≥8.0 mmol/L). Besides, the patients were divided into a PPCs group and a non-PPCs group according to whether PPCs occurred. The risk factors for PPCs were analyzed by logistic regression analysis, and the predictive value of preoperative FPG level on PPCs was estimated by the area under the receiver operating characteristic curve (AUC). Results A total of 130 patients were included, including 75 (57.7%) males and 55 (42.3%) females with an average age of 63.5±9.0 years. Logistic regression analysis showed that compared to non-PPCs patients, the level of preoperative FPG (P=0.023) and smoking history ratio (P=0.036) were higher and the operation time was longer (P=0.004) in the PPCs patients. High FPG level on preoperative day 1 and longer operation time were associated with PPCs risk. Besides, the preoperative FPG of 6.79 mmol/L was the threshold value to predict the occurrence of PPCs [AUC=0.653, 95%CI (0.559, 0.747), P=0.003]. Conclusion There is a certain correlation between preoperative FPG level and postoperative PPCs, which may be used as an index to predict the occurrence of PPCs.
ObjectivesTo conduct an overview of systematic reviews (SRs) on Tuina from 2013 to 2017, and to explore recent research improvements on Tuina.MethodsPubMed, Web of Science, The Cochrane Library, SpringerLink e-book database, CNKI, VIP, WanFang Data and CBM databases were searched to collect SRs including randomized controlled clinical trials on Tuina from January 1st, 2013 to December 31st, 2017. Two reviewers independently screened literature, extracted data, and used AMSTAR 2 tool and PRISMA statement to assess methodology quality and reporting quality of included studies, respectively. The R 3.4.3 software was used to analyze data.ResultsA total of 8 SRs studies were included in the overview. The studied diseases involved radiculopathy cervical spondylotic, myelopathy cervical spondylotic, constipation, child anorexia, child diarrhea and external humeral epicondylitis. The results of above SRs showed that massage might be superior to other interventions in clinical efficacy, curative effects or total effective rate. However, due to the low quality of included studies of SRs, further evidence from high-quality clinical studies is required to verify above conclusions. For the results of AMSTAR 2 assessment, all 8 SRs were rated as very low quality. The quantity of items accomplished for each SR ranged from 7 to 13, 2 SRs had low methodological quality (percentage of accomplishment or partial accomplishment <50.0%) and 6 SRs with high methodological quality (percentage of accomplishment or partial accomplishment ≥50.0%). All 8 SRs did not report item 2 "Whether to declare research methods", item 10 "Whether reports have included funding sources for each study" and item 11 "Whether reports used the correct statistical method". The results of PRISMA assessment showed that all SR had good quality of reporting. The accomplished items number of each SR ranged from 22 to 26. However, there were defects in item 5(0), item 16(25.0%) and item 23(25.0%). All SRs did not report item 5 "Whether to declare research program".ConclusionsThis study finds that Tuina has supportive evidence-based medical evidence for treating anorexia, cervical spondylosis and other diseases, however, the SRs of Tuina are yet needed to be improved in terms of standardized degree. Therefore, establishing a reporting consolidated standard for evidence-based medicine on Tuina in order to improve the quality of clinical studies so as to provide clinicians with high-quality evidence is the focus of our further research.
