Efficacy and safety of Chuankezhi injection in patients with chronic obstructive pulmonary disease: A systematic review and meta-analysis protocol.

BACKGROUND: Chuankezhi injection (CKZ) is gaining increasing popularity for chronic obstructive pulmonary disease (COPD) treatment, yet their comparative effectiveness and safety remain unclear. Therefore, we will provide a protocol to assess the efficacy and safety of CKZ for COPD. METHODS: From now until June 2020, we will conduct a comprehensive and systematic literature search in 4 Chinese and 4 English databases, and the use of CKZ in the treatment of COPD will be included in randomized controlled trials, as well as all the treatment of stable COPD during the treatment of all CKZ. The risk assessment of the bias tool in Cochrane 5.1.0 will be combined with the quality of the trial. The 2 investigators will independently perform quality assessments and data extractions for the included studies in strict accordance with inclusion and exclusion criteria and perform the meta-analysis with Stata 15 software (version 15.0, StataCorp, College Station, TX). RESULTS: Further evidence of CKZ treatment for COPD will be provided by this study. CONCLUSION: The efficacy and safety assessment of CKZ for COPD will be supported by this protocol.

[Meta-analysis and trial sequential analysis of modified Sangbaipi Decoction for treating acute exacerbation of chronic obstructive pulmonary disease].

The randomized controlled trials about modified Sangbaipi Decoction in the treatment of acute exacerbation of chronic obstructive pulmonary disease( AECOPD) patients were collected from 7 databases( PubMed,CNKI,et al) from the establishment to December 5,2018. All the studies searched were strictly evaluated. Literatures were independently screened by two researchers according to the inclusion and exclusion criteria,and the methodological quality of included studies was evaluated. To systematically review the efficacy of modified Sangbaipi Decoction in treating AECOPD,the Meta-analysis and trial sequential analysis were conducted by using Stata/SE 14. 0 and TSA 0. 9. 5. 10 Beta,respectively. A total of 25 RCTs involving 1 784 patients were included. According to the results of Meta-analysis,compared with the control groups,the trial group had a higher clinical efficacy in AECOPD patients( RR =1. 18,95%CI[1. 13,1. 22],P = 0),improved pulmonary functions including forced expiratory volume in one second( FEV1,WMD =0. 44,95%CI[0. 01,0. 87],P = 0. 046),and the forced vital capacity( FVC,WMD = 0. 42,95%CI[0. 07,0. 22],P = 0),but no statistical significance in the percentage of forced expiratory volume in one second( FEV1%,P = 0. 067) and the first seconds breathing volume percentage of forced vital capacity( FEV1/FVC,P = 0. 238); it improved the arterial oxygen partial pressure( PaO2,SMD =0. 85,95%CI[0. 41,1. 30],P = 0) and decreased the arterial partial pressure of carbon dioxide( PaCO2,SMD =-0. 94,95% CI[-1. 70,-0. 18],P= 0. 016); and in terms of inflammatory markers,it improved the white blood cell count( WBC,WMD=-0. 94,95%CI[-1. 17,-0. 70],P = 0). The trial sequential analysis showed that the studies included with the improvement of clinical efficacy had passed the conventional and TSA threshold,so as to further confirm the evidence. According to the findings,in addition to conventional Western medicine treatment,modified Sangbaipi Decoction could improve the efficiency in treating acute exacerbation patients with chronic obstructive pulmonary disease,increase PaO2,and decrease PaCO2,with a high safety but no effect on pulmonary function. However,restricted by the low quality of studies included,this conclusion shall be further verified by more high-quality clinical trials.

Chuankezhi injection for asthma: Protocol of a systematic review and meta-analysis.

BACKGROUND: Asthma is a chronic inflammatory disease characterized by recurrent attacks of breathlessness and wheezing, which often worsen at night or in the early morning and vary from person to person in severity and frequency. Chuankezhi injection (CKZ), as a new Chinese medicine, was recently found to have a good clinical effect on asthma. Whereas neither systematic nor meta-analysis of randomized controlled trials (RCTs) explain the efficacy of CKZ in treating asthma. Therefore, we provide a protocol to evaluate the efficacy and safety of CKZ for asthma. METHODS: From inception until April 2019, a systematic and comprehensive literature search will be conducted in both 4 Chinese databases and 3 English databases. RCTs will be included related to CKZ for asthma. We will assess the quality of the included trials in accordance with the risk of bias tools in Cochrane manual 5.1.0. We will use the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method to assess the certainty of the estimated evidence. Data analysis will be performed using the STATA 15.0. RESULTS: This systematic review aims to assess the effectiveness and safety of CKZ for the treatment of asthma, in order to provide evidence for the clinical practice of Chinese medicine. This protocol will be conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) statement. The results of this meta-analysis will be submitted to a peer-reviewed journal once it is completed. CONCLUSION: The consequence of this study will furnish proof to evaluate if CKZ is effective in the treatment of asthma. PROSPERO REGISTRATION NUMBER: ROSPERO CRD42019134458.

Outcome and complications of endovascular embolization for vein of Galen malformations: a systematic review and meta-analysis.

OBJECT: There have been many multidisciplinary approaches to the treatment of vein of Galen malformations. Endovascular embolization is the first option for treatment. However, the effects of the treatment remain controversial. The aim of this study is to assess the efficacy and safety of endovascular embolization to treat patients with vein of Galen malformations. METHODS: This paper includes a retrospective analysis of a sample of 667 patients who underwent endovascular embolization to treat vein of Galen malformations. The data were obtained through a literature search of PubMed databases. The authors also evaluate the efficacy and safety of the treatment. Mortality within the follow-up period is analyzed. Pooled estimates of proportions with corresponding 95% CIs were calculated using raw (i.e., untransformed) proportions (PRAW). RESULTS: In the 34 studies evaluated, neonates accounted for 44% of the sample (95% CI 31%-57%; I(2) = 92.5%), infants accounted for 41% (95% CI 30%-51%; I(2) = 83.3%), and children and adults accounted for 12% (95% CI 7%-16%; I(2) = 52.9%). The meta-analysis revealed that complete occlusion was performed in 57% (95% CI 48%-65%; I(2) = 68.2%) of cases, with partial occlusion in 43% (95% CI 34%-51%; I(2) = 70.7%). The pooled proportion of patients showing a good outcome was 68% (95% CI 61%-76%; I(2) = 77.8%), while 31% showed a poor outcome (95% CI 24%-38%; I(2) = 75.6%). The proportional meta-analysis showed that postembolization mortality and complications were reported in 10% (95% CI 8%-12%; I(2) = 42.8%) and 37% (95% CI 29%-45%; I(2) = 79.1%), respectively. Complications included cerebral hemorrhage, cerebral ischemia, hydrocephalus, leg ischemia, and vessel perforation. CONCLUSIONS: The successful treatment of vein of Galen malformations remains a complex therapeutic challenge. The authors' analysis of clinical history and research literature suggests that vein of Galen malformations treated with endovascular embolization can result in an acceptable mortality rate, complications, and good clinical outcome. Future large-scale, multicenter, randomized trials are necessary to confirm these findings.

Intracranial meningioma surgery in the elderly (over 65 years): prognostic factors and outcome.

BACKGROUND: Meningiomas are more prevalent in elderly individuals; however, the surgical outcome and prognostic factors in this age group are unclear. This retrospective study aimed to identify the prognostic factors of elderly patients with intracranial meningiomas who underwent surgical resection. METHODS: Eighty-six patients (aged ≥ 65) diagnosed with an intracranial meningioma were surgically treated at our department. The clinical, radiological, and follow-up data were retrospectively reviewed. Univariate and multivariate logistic analyses were performed to identify relationships between factors [age, sex, neurological condition, concomitant disease, American Society of Anesthesiology (ASA) classification, preoperative Karnofsky Performance Scale (KPS) score, tumor location and size, peritumoral edema, and Simpson resection grade] and outcome. RESULTS: One patient (1.2 %) died within 30 days of surgery. The morbidity rate was 37.2 %. Postoperative morbidities occurred more frequently in the patients with preoperative neurological deficits than in those without (p = 0.049). Univariate analysis identified significant relationships between a low KPS score (≤ 70) at discharge and preoperative neurological deficits, low preoperative KPS score (≤ 70), and critical tumor location (p < 0.001, p < 0.001, and p = 0.04, respectively). In the multivariate logistic analysis, only the preoperative KPS score remained significant for the KPS score at discharge (p = 0.005); there was no significant association with the most recent KPS score. CONCLUSION: The outcome of intracranial meningioma resection in elderly individuals is favorable if the preoperative KPS score is >70 and no neurological deficits are present. Treatment decisions should be patient-specific, and additional factors should be considered when operations are performed in patients with a low preoperative KPS score or neurological deficits.

[Microsurgical resection of anterior clinoid meningiomas-- 46 cases report].

OBJECTIVE: To investigate the microsurgical tchniques and effects for the resection of anterior clinoid meningioma (ACM). METHODS: Between January 2003 and March 2013, a total of 46 ACM patients were operated on via the pterion approach or lateral subfrontal approach. There were 16 male patients and 30 female patients, their mean age was 48.5 (16-69) years. Symptoms lasted from 1 month to 9 years(average 24.7 months). Preoperative CT and MRI examination showed that the tumors were located in the anterior clinoid process (25 cases on the right side, 21 cases on the left side). The average maximal tumor diameter was 4.4 cm (1.9-7.4 cm). The patients were peroidly followed-up on outpatient on 3 months to 6 months, then every year postoperativelly. The clinical data, radiological findings, surgical records and outcome of patients were retrospectively analyzed, and the prognostic factors were ananlyzed by using of the unpaired data χ(2) test with continuity correction. RESULTS: Of fourty-six patients operated on, apparently complete removal was achieved in 36 patients (78.3%), 10 patients (21.7%) had minimal residual tumors, 5 of which had gamma knife radiosurgery. Preexisting visual deficit improved in 21 of 41 patients (51.2%), unchanged in 16(35.6%), and worsened in 9(20.0%). At 3-6 months after discharge, 37(80.4%) patients had a good recovery, 7(15.6%) patients were moderately disabled, 1(2.2%) presented with severe disability, and 1 (2.2%) patient died of surgery-related causes. The tumor wrapping blood vessels (χ(2) = 4.676, P = 0.031) and violating cavernous sinus(χ(2) = 4.973, P = 0.026) were causes of unfavorable prognosis. During the mean follow-up of 35.1 months (range, 4-107 months) for 40 patients, the average Karnofsky score was 83.2. Tumor recurred in 4 cases: 2 of which required reoperation, and 2 had gamma knife radiosurgery. CONCLUSIONS: Tumor wrapped vessels and invasion of the cavernous sinus are important unfavorable prognostic factors for ACM resection. By using appropriate surgical strategies and techniques, ACM can be removed safely via the pterion approach or lateral subfrontal approach with relatively low morbidity and mortality.

[Lumbar interbody fusion impacted bone grafts combined with regrafting in situ with spinous process and vertebral plate complex and pedicle screw fixation for lumbar degenerative instability].

OBJECTIVE: To evaluate the effectiveness of lumbar interbody fusion impacted bone grafts combined with regrafting in situ with spinous process and vertebral plate complex and pedicle screw fixation for lumbar degenerative instability. METHODS: Between January 1998 and October 2010, 48 patients with lumbar degenerative instability were treated by posterior decompression, lumbar interbody fusion impacted bone grafts combined with regrafting in situ with spinous process and vertebral plate complex and pedicle screw fixation. There were 26 males and 22 females, aged 52-76 years (mean, 62.4 years). The disease duration was 7 months to 25 years (mean, 6.5 years). One segmental instability was located at L(3, 4) in 1 case, at L(4, 5) in 10 cases, and at L5, S1 in 11 cases; multi-segmental instability was located at L(3, 4), L(4,5), and L5, S1 in 5 cases, at L(2,3) and L(3,4) in 2 cases, at L(3, 4) and L(4, 5) in 10 cases, and at L(4, 5) and L(5), S1 in 9 cases. Of 48 patients, 32 complicated by lumbar disc herniation, 46 by lumbar spinal stenosis, and 16 by degenerative scoliosis. The clinical results were evaluated by the Japanese Orthopaedic Association (JOA) score, recovery rate, disc height, and lumbar lordosis angles. RESULTS: The incisions obtained healing by first intention after operation. No nerve injury, rod or screw breakage, and infection occurred during and after operation. All 48 patients were followed up 1 to 6 years. The fusion time was 12-18 weeks (mean, 16.2 weeks). Vertebra slipping or degenerative scoliosis was corrected, and spinal column series became normal. At preoperation, 6 months after operation, and last follow-up, the disc heights were (5.2 +/- 2.3), (11.9 +/- 2.0), and (11.6 +/- 2.1) mm, respectively; the JOA scores were 3.2 +/- 2.1, 12.8 +/- 1.6, and 13.6 +/- 1.2, respectively; and the lumbar lordosis angles were (-20.5 +/- 10.5), (30.5 +/- 8.5), and (31.2 +/- 5.6) degrees, respectively. The JOA scores, disc heights, and lumbar lordosis angles were significantly improved at 6 months after operation and last follow-up when compared with preoperative ones (P < 0.05), but no significant difference was found between 6 months after operation and last follow-up (P > 0.05). The recovery rate of JOA was excellent in 36 cases, good in 10 cases, and fair in 2 cases at 6 months after operation, with an excellent and good rate of 95.8%. CONCLUSION: Lumbar interbody fusion impacted bone grafts combined with regrafting in situ with spinous process and vertebral plate complex and pedicle screw fixation for lumbar degenerative instability can restore and maintain the intervertebral disc height effectively with high fusion rate. It is a plasty close to anatomic reconstruction.
