ObjectiveTo investigate the situation of off-label drug use in dose (OLDUD) of ambroxol hydrochloride injection (AHI) in perioperative period among patients for stanford type A aortic dissection in Guangdong General Hospital, so as to provide references for the rational application of AHI in clinical practice. MethodsAll medical orders of AHI for patients had aortic arch replacement for Stanford type A aortic dissection in Guangdong General Hospital between January 2005 and December 2014 were included. The patients were divided into a mild OLDUD ( < 450 mg) group, a moderate OLDUD (450 mg≤OLDUD < 900 mg) group, and a high OLDUD (≥900 mg)group. The preoperative and postoperative features, incidence of PPCs, mortality, incidence of reintubation, time of mechanical ventilation, time stay in ICU, time stay in hospital and the overall costs among three groups were compared by SPSS 22.0 software. Resultsa) A total of 549 patients were included. The incidence of OLDUD was 99.82%. The most common PMDDs were 450 mg (n=358) and 900 mg (n=88). b) The three groups were well matched for perioperative and operative variables. c) The incidence of preoperative drug use was 8.6%. The incidences (5.5% vs. 7.7% vs. 15.7%, P=0.022) and maximum doses (180 mg vs. 300 mg vs. 450 mg, P=0.014) of preoperative drug use were statistically different in mild OLDUD, moderate OLDUD and high OLDUD groups. The days of preoperative drug use were not different (3 d vs. 2.5 d vs. 2 d, P=0.307). The days of postoperative drug use (9.5 d vs. 13 d vs. 19 d, P < 0.001) and postoperative drug use in maximum doses (7 d vs. 8 d vs. 7 d, P=0.005) were different. d) The incidence of PPCs was 100%, and the mortality (8.2% vs. 6.6% vs. 9.0%, P=0.696) was not statistically different among mild OLDUD, moderate OLDUD and high OLDUD groups. However the incidence of reintubation (14.3% vs. 13.8% vs. 27%, P=0.009), time of mechanical ventilation (37 h vs. 50 h vs. 114 h, P < 0.001), time stay in ICU (138 h vs. 178.5 h vs. 316 h, P < 0.001), time stay in hospital (25 d vs. 27 d vs. 34 d, P=0.001) and the overall costs (￥ 0.17 million vs. ￥ 0.19 million vs. ￥ 0.25 million, P < 0.001) were different among three groups. Moreover, they were all increasing along with the dose of AHI. ConclusionAHI cannot improve the prognosis of patients having aortic arch replacement for Stanford Type A Aortic Dissection in a dose-dependent manner. Further well-designed prospective studies should be conducted to verification or falsification.
Objective To determine the best matching concentration of carbon nanoparticles suspension injection adsorb epirubicin by measuring the combination ratio of carbon nanoparticles suspension injection combined with epirubicin under different matching conditions. And then, to prove the adsorbability of carbon nanoparticles suspension injection adsorb epirubicin in vitro. Methods Firstly, epirubicin-carbon suspension of different concentrations will be prepared. The second, high performance liquid chromatography mass spectrometry（LC-MS） was used to assay the concentration of free epirubicin, and calculate the content of epirubicin that was combinated with carbon nanoparticles suspension injection. The difference of the ratio of carbon nanoparticles suspension injection combined with epirubicin under different matching conditions will be compared in the end. Results The combination ratio of carbon nanoparticles suspension injection combined with epirubicin solution of 5, 10, and 15 mg/ml were 85.6%, 85.7%, and 31.8%, respectively. Conclusions The adsorbability of carbon nanoparticles suspension injection adsorb epirubicin is favourable in vitro. Best matching concentration of carbon nanoparticles suspension injection adsorb epirubicin may be epirubicin solution of 5-10 mg/ml.
Objective To compare the clinical effects of two surgical approaches to treatment of horseshoe kidney.Methods From January 1965 to December 1982, 15 patients (11 males, 4 females; aged 14 months to 59 years with a median of 31 years) with horseshoe kidney underwent surgical treatment by the waist cretroperitoneal approach (the waist-approach group). The clinical symptoms and signs were as follows:pain in the waist and abdomen (12 patients), hematuria (7), urinary frequency (4), gastrointestinal disorder (3), and abdominal masses (2). The urography revealed urinary calculus in 10 patients, hydronephrosis in 3, renal cyst in 1, pyonephrosis in 1, renal tuberculosis in 1, and renal cell carcinoma in 1. From January 1977 to December 2005, 17patients (15 males, 2 females; aged 11 months to 56 years with a median of 29.4years) with horseshoe kidney underwent surgical treatment by the epigastric transperitoneal approach (theabdomenapproach group). The clinical symptoms and signs were as follows:pain in the waist and abdomen (15patients), hematuria (12), urinary frequency (10), gastrointestinal disorder (9), and abdominal masses (7). Theurography revealed urinary calculus in 12 patients, hydronephrosis in 10,renal cyst in 3, renal tuberculosis in 1, renal cell carcinoma in 1, and congenital spinal bifida in 1. The two surgical approaches were compared in the clinical therapeutic effects. Results There were no statistically significant differences in operating time, blood loss during operation, and the hospitalization after operation between the waistapproach group and the abdomen-approach group (129.59±23.25 min vs. 163.80±36.25min; 495.29±87.20ml vs. 553.00±92.27ml；13.17±1.14d vs. 13.75±0.21d; Pgt;0.05). Thepostoperative followup for 7 months to 6 years in 11 patients in the waistapproach group and in 6 patients in the abdomenapproach group revealed that there were statistically significant differences in postoperative complication and the recurrence rate of the renal calculus between the two groups (11.76%, 2/17 vs 26.67%, 4/15; 33.33%, 5/15 vs. 0, 0/17; Plt;0.05). The urography or CT taken 6 months to 2 years after operation in 4 patients in the waistapproach group and in 10 patients in the abdomenapproach group revealedthat there was a significant improvement hydronephrosis when compared with before operation.
Objective To explore the serious situation of injection abuse, and its influence to average prescription fee. Methods The subjects of this study were health service settings in rural area of 9 provinces/cities in Midwest of China. The treatment prescription indicators of county and village health service settings were calculated. Results Prescription injection rates of health care facility in rural area of Midwest provinces/cities of China (25.8% to 62.2%,mean: 45.1%) were higher than the standard of WHO (13.4% to 24.1%), and the injection abuse situation was serious. Injection bause caused the increase of prescription fee. Excess usage of injection in health service settings was related to the economic level of the on-site county or village, and also related to the size and load of health service facilities. Conclusion Suggestions are proposed to the government health agency according to the results of the study: enhancing the lawmaking, establishing the related policy and effective measure, training the medical personnel, promoting the mass health education, investigating the effective injection management model in rural area, and reducing the rate of injection.
ObjectiveTo explore the clinical efficacy and safety of ultrasound-guided intra-articular injection of platelet-rich plasma (PRP) in the treatment of avascular necrosis of the femoral head.MethodsWe retrospectively collected and analyzed the clinical characteristics, imaging data, and clinical outcomes of patients with femoral head necrosis who received ultrasound-guided intra-articular PRP injection in the Department of Rehabilitation Medicine of Sun Yat-sen Memorial Hospital, Sun Yat-sen University between June 2019 and June 2020. All the patients received 4 injections at one-week intervals. The Visual Analogue Scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and Harris Hip Joint Function Scale (HHS) were evaluated before treatment and 1 month, 3 months, and 6 months after the first injections. Adverse events were recorded. The normally distributed data were presented as mean±standard deviation, and analyzed by one-way repeated measures analysis of variance; the non-normally distributed data were presented as median (lower quartile, upper quartile), and analyzed by Friedman test.ResultsA total of 29 patients were included. According to the Association Research Circulation Osseous classification standard, 2 patients were classified as stageⅠ, 11 as stageⅡ, 11 as stage Ⅲ, and 5 as stage Ⅳ. Before treatment and 1 month, 3 months, and 6 months after treatment, the VAS scores were 7.0 (5.5, 8.0), 4.0 (3.0, 5.0), 3.0 (2.0, 3.0), and 3.0 (2.0, 5.0), respectively, the WOMAC scores were 39.27±11.70, 28.34±8.08, 22.82±6.09, and 24.13±7.55, respectively, and the HHS were 46.0 (40.0, 64.0), 71.0 (57.5, 75.0), 78.0 (68.0, 80.5), and 78.0 (64.0, 80.0), respectively. The time effects in VAS (χ2=65.423, P<0.001), WOMAC (F=46.710, P<0.001), and HHS (χ2=66.347, P<0.001) were all statistically significant. There were significant differences in each index between the values 1 month, 3 months, and 6 months after treatment and those before treatment respectively, and there was also a significant difference in each index between the value 1 month after treatment and that 3 months after treatment (P<0.05). There was no significant difference in any indicator between the value 6 months after treatment and that 3 months after treatment (P>0.05). Significant difference was shown between the value 6 months after treatment and that 1 month after treatment in WOMAC (P=0.016), but not in VAS or HHS (P>0.05). No obvious adverse event was reported during the follow-up period.ConclusionsUltrasound-guided intra-articular PRP injection can effectively alleviate the pain and improve the hip joint function of patients with femoral head necrosis for at least 6 months. However, randomized controlled studies with a larger sample size and longer-term follow-up are needed in the future to confirm the efficacy and safety of PRP injection in femoral head necrosis.
ObjectiveTo evaluate the effects and safety of ginkgo leaf extract and dipyridamole combined with betahistine injection for the treatment of vertebrobasilar ischemia with vertigo. MethodsThe Cochrane Library, Medline, Embase, Web of Science, China National Knowledge Infrastructure, VIP Database, Wanfang Database and China Biology Medicine Databases were searched from their establishment to September 2015. We used the method recommended by the Cochrane collaboration to perform a meta-analysis on randomized controlled trails. ResultsSix studies were included. The results of meta-analysis demonstrated that ginkgo leaf extract and dipyridamole combined with betahistine injection for the treatment of vertebrobasilar ischemia with vertigo was superior to either ginkgo leaf extract and dipyridamole or betahistine injection in total effective rate[RR=1.21, 95%CI (1.08, 1.35), P=0.000 7; RR=1.17, 95%CI (1.05, 1.31), P=0.006]. ConclusionGinkgo leaf extract and dipyridamole combined with betahistine injection is effective for the treatment of vertebrobasilar ischemia with vertigo. However, due to the limited quantity and quality of the included studies, the results need to be further confirmed.
Objective To explore the change of particles of Shuanghuanglian Injection (SHLI) admixed with different infusion solutions, and provide a reference for selecting rational menstruum. Methods A comprehensive literature search was executed to collect all the studies on the compatibility of SHLI with different infusion solutions. The reporting quality of the included studies was assessed; particles-related data were extracted and analyzed systematically. Results A total of 338 studies were identified, and 24 studies were included after screening. The quality of the included studies were poor and had heterogeneous outcomes. Generally, the particles of mixture increased dramatically, and there were significant differences among different pharmaceuticals, drug batches and infusion solutions. The pH of solvent had a greater impact on the particles, and the concentration and storage time of prepared liquor were other important factors. The particles of SHLI admixed with Normal Saline were less than 5%, 10% glucose injection and other solvents. Conclusion The particles of SHLI admixed with Normal Saline are the fewest, and commonly can be the preferred solvent. Factors on rational drug use are worthy of further studies; and more attention is needed for the scientificalness of study design.
OBJECTIVE To investigate the effects of sodium hyaluronate in supplementary treatment of comminuted fracture of ankle. METHODS Thirty-seven patients suffered from comminuted fracture of ankle were operated for restoration by routing methods, and received 2 ml of sodium hyaluronate injection intra-articularly before the closure of incision. The ankle was fixed and given the second intra-articular injection on the 3rd day after operation. Then, the patients were given sodium hyaluronate injection intra-articularly at a week intervals till the paste was removed after 4 weeks. All patients were followed up. The clinical results were evaluated by measuring the symptoms of pain, and the function of walking and other daily living activities. RESULTS All the patients were followed up for 6 to 27 months, among them, 30 patients were cured completely without any symptoms, the ankle function for walking and daily living activities was normal, 6 patients felt pain with violent activity or walking exceeding 1 km, one patient suffered from comminuted fracture with compressed depression was not improved due to his ankle being not restored properly. CONCLUSION Intra-articular injection of sodium hyaluronate is an effective supplementary treatment for comminuted fracture of ankle.
Objective To evaluate the therapeutic results of percutaneous injection of autogeous bone marrow for simple bone cyst and to analyze the prognostic factors of the treatment. Methods From March 2000 to June 2005, 31 patients with simple bone cysts were treated by percutaneous injection of autogeous bone marrow. Of 31 patients, there were 18 males and 13 females, aged 5 years and 7 months to 15 years. The locations were proximal humerus in 18 cases ,proximal femur in 7 cases and other sites in 6 cases. Two cases were treated with repeated injections. The operative process included percutaneous aspiration of fluid in the bone cysts and injection of autogenous bone marrow aspirated fromposterior superior iliac spine. The mean volume of marrow injected was 40 ml(30-70 ml).Results No complications were noted during treatment. Thirty patients were followed for an average of 2.2 years(1.5 years) with 2 cases out of follow-up. After one injection of bone marrow, 9 cysts(29.0%) were healed up completely, 7 cysts(226%)basically healed up,13 cysts (41.9%)healed up partially and 2 (6.5%) had no response.The satisfactory and effective rates were 67.7% and 93.5% respectively. There was significant difference between active stagegroup and resting stage group(P＜0.05). There were no statistically significant difference in therapeutic results between groups of different ages, lesion sites or bone marrow hyperplasia(Pgt;0.05). Conclusion Percutaneous injection of autogeous bone marrow is a safe and effective method to treat simple bone cyst, but repeated injections is necessary for some patients. The therapeutic results are better in cysts at resting stage than those at active stage.
ObjectiveTo systematically review the efficacy of Chinese medicine injection (CMI) for treating heart failure (HF).MethodsCNKI, WanFang Data, VIP, The Cochrane Library, PubMed, and EMbase databases were electronically searched from inception to January 2021 to identify randomized controlled trials (RCTs) on CMI for treating HF. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of included studies. Network meta-analysis was then performed by RevMan 5.2 software and Stata 16.0 software.ResultsA total of 47 studies were included involving 4 902 patients and 5 types of CMIs, including Shenmai, Shenfu, Yiqi Fumai (lyophilized), Shengmai, and Danhong injections. The results of network meta-analysis showed that the efficacy of combined CMIs was superior to conventional Western medicine alone. For the main efficacy, Shenmai, Shengmai, and Shenfu injections had significant advantages in improving the total clinical effectiveness. Shengmai, Shenmai, and Yiqi Fumai (lyophilized) injections were significantly more effective for reducing NT pro-BNP levels than other injections. Shenfu and Shengmai injections were significantly more effective for reducing BNP levels than other injections. Shenmai, Danhong and Shengmai injections were significantly more effective for improving the left ventricular ejection fraction than the other injections. These CMIs showed similar advantages for secondary efficacy indicators as for main efficacy indicators.ConclusionsThe combined 5 types of CMIs for treating HF can improve the clinical efficacy when compared with conventional Western medicine treatment. Shenmai injection, Yiqi Fumai injection (lyophilized), and Shengmai injection, which is part of Sheng Mai San, have clear advantages in terms of the overall curative effect or on individual indices.
