Objective To evaluate the effectiveness and safety of different Chinese patent medicine in improving blood lipid and microcirculation in coronary heart disease patients with phlegm-blood stasis syndrome based on network meta-analysis.Methods The randomized controlled trials(RCTs)of different Chinese patent medicine in the treatment of blood lipid and microcirculation in coronary heart disease patients with phlegm-blood stasis syndrome were collected by searching CNKI,Wanfang,VIP,SinoMed,PubMed,EMbase,Cochrane Library,and Web of science databases from the establishment of the database to April 3,2023.Literature quality evaluation and network meta-analysis were conducted using Review Manager 5.4 and Stata15.1 software.Results Thirty-seven RCTs were included,with a total sample size of 4 064 cases,involving 15 different Chinese patent medicines.The network meta-analysis showed that the efficacy of Chinese patent medicine combined with conventional Western medicine is often better than that of conventional Western medicine alone.There are no serious adverse reactions.The top three Chinese patent medicines with cumulative probability of total clinical efficacy were Guanmai Zaitong soft extract,Gualoupi Injection and Quyu Xiaoban Capsule.In terms of improving triglyceride(TG)and low-density lipoprotein(LDL-C),the top three Chinese patent medicines were Gualoupi Injection,Huxinkang Tablet and Guanxin Shutong Capsule.In terms of improving plasma viscosity and fibrinogen,the top three Chinese patent medicines were Ginkgo Damo Injection,Gualoupi Injection and Guanxin Shutong Capsule.In terms of improving endothelial function[nitric oxide(NO)and endothelin-1(ET-1)],the top three Chinese patent medicines were Ginkgo Damo Injection,Danlou Tablet and Tongmai Yuxin Pill.In terms of reducing inflammation hypersensitivity C-reactive protein(hs-CRP),the top three Chinese patent medicines were Ginkgo Damo Injection,Huxinkang Tablet and Guanxin Shutong Capsule.Conclusion The current evidence shows that the combination of TCM,which is used for the treatment of phlegm-blood stasis syndrome,with conventional Western medicine in the treatment of coronary heart disease has advantages in improving clinical efficacy,blood lipids and microcirculation.TCM especially for the treatment of phlegm-blood stasis syndrome shows more obvious advantage,such as Guanmai Zaitong soft extract and Gualoupi injection,which can be taken into consideration as part of the clinical guidelines.However,due to the limited number and quality of the included literatures,the research results still need to be verified by more high-quality,multi-center,double-blind randomized trials.The purpose is to provide more reliable evidence-based medical reference.

Objective To evaluate the effect of body mass index (BMI) on early prognosis of the recipients after lung transplantation. Methods Clinical data of 307 lung transplant recipients were retrospectively analyzed. According to preoperative BMI, all recipients were divided into the low (BMI <18.5 kg/m², n=114), normal (18.5 kg/m²≤BMI <24 kg/m², n=145) and high (BMI≥24.0 kg/m², n=48) BMI groups, respectively. Baseline data including age, sex, blood type, BMI, preoperative complications, preoperative pulmonary hypertension, and intraoperative use of extracorporeal membrane oxygenation (ECMO) of all recipients were compared among three groups. The survival rate of all recipients was estimated by Kaplan-Meier curve and the survival curve was delineated. The differences of survival rate were analyzed by log-rank test. The 30-, 90- and 180-d mortality risk of all recipients after lung transplantation in different BMI groups was compared by multivariate Cox regression analysis. Results There were significant differences in age and sex of recipients among three groups (both P<0.05). There was a significant difference regarding the 180-d survival rate after lung transplantation among different BMI groups (P<0.05). Multivariate Cox regression analysis showed that the 90-d mortality risk after lung transplantation in the high BMI group was 2.295 times higher than that in the normal BMI group [hazard ratio (HR) 2.295, 95% confidence interval (CI) 1.064-4.947, P=0.034]. In the high BMI group, the 180-d mortality risk after lung transplantation was 2.783 times higher compared with that in the normal BMI group (HR 2.783, 95%CI 1.333-5.810, P=0.006), and the 180-d mortality risk in the low BMI group was 2.181 times higher than that in the normal BMI group (HR 2.181, 95%CI 1.124-4.232, P=0.021). Conclusions Compared with the recipients with normal BMI, their counterparts with high and low preoperative BMI have higher mortality risk early after lung transplantation. Adjusting preoperative BMI to normal range contributes to improving early prognosis of lung transplant recipients.

OBJECTIVE: To assess the early clinical effects of oblique lateral lumbar interbody fusion (OLIF) combined with posterior long-segment internal fixation through O-arm CT navigation for the treatment of degenerative scoliosis. METHODS: The clinical data of 15 patients with degenerative scoliosis treated by OLIF combined with posterior long-segment internal fixation through O-arm CT navigation between April 2016 and December were retropectively analyzed. There were 3 males and 12 females, aged from 55 to 73 years old with an average of (62.2±5.3) years. The operation time, intraoperation blood loss, the rate of excellentand good of pedicle screw placement, and complications were recorded. Before surgery, 1 week after surgery and at the final follow-up, the visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the patients' clinical symptoms;standing X-ray film, lumbar spine CT examination was performed at 6 months after surgery to observe coronal scoliosis Cobb angle, lumbar lordosis (LL), intervertebral space height, sagittal vertical axis (SVA), intervertebral fusion, etc. RESULTS: The mean operation time and intraoperative blood loss were respectively (98.7±16.8) min and (50.2±10.7) ml in OLIF surgery, while were (101.5±23.4) min and (63.1±19.7) ml in the surgery of posterior long segment internal fixation. The total mean operation time and intraoperative blood loss were (200.2±40.2) min and (113.3±30.4) ml. All patients were followed from 12 to 25 months with an average of (16.5±5.3) months. Low back pain VAS, lower limb pain VAS and ODI reduced from preoperative (6.8±1.6), (6.2±1.1) scores and (64.6±10.4)% to (1.4±1.0), (1.0±0.5) scores, and (15.8±4.5)% at the final follow-up, the differences were statistically significant(<0.05). Coronal scoliosis Cobb angle and SVA decreased from preoperative (20.3±13.5)°, (42.3±16.5) mm to (5.5±3.1)°, (25.1±10.9) mm at the final follow-up, and the differences were statistically significant (<0.05). LL and intervertebral space height increased from preoperative (25.8±8.2)°, (5.9±2.7) mm to (39.3±9.1)°, (10.9±1.2) at the final follow-up, and the differences were statistically significant(<0.05). Total 240 nails were placed through O-arm CT navigation with the rate of excellent and good of 96%(230/240). Six months after operation, CT of lumbar spine showed interbody fusion of bone. One patient developed anterior medial pain in the left thigh, and two patients experienced transient lefthip flexion after surgery, both of whom recovered during subsequent follow-up. CONCLUSION The early clinical effect of oblique lateral lumbar interbody fusion combined with posterior long segment internal fixation through O-arm CT navigation is satisfactory in treatment of degenerative scoliosis. It has the advantages of minimal invasion, accurate navigation of nail placement, high bone fusion rate and few complications. It can provide new options for minimally invasive treatment of degenerative scoliosis.

OBJECTIVE: To explore the clinical effects of anterior cervical discectomy with fusion (ACDF) and anterior cervical corpectomy with fusion (ACCF) in treating adjacent two-segment cervical spondylotic myelopathy (CSM). METHODS: The clinical data of 37 patients with adjacent two segment CSM treated from January 2016 to December 2017 were retrospectively analyzed, including 15 males and 22 females, aged from 43 to 69 years old with an average of 54.6 years. The patients were divided into ACDF group (group A, =17) and ACCF group (group B, =20) according to the different surgery. The operation time and intraoperative blood loss were recorded;the Cobb angle and cervical curvature in the cervical fusion segments before surgery and 1, 12 months after surgery were observed;Japanese Orthopaedic Association (JOA) score was used to evaluate the surgical efficacy, and the postoperative complications were analyzed. RESULTS: All patients were followed up for 12 to 24 months with an average of 18.5 months. Operation time and intraoperative blood loss in group A were (106.3±22.6) min, (52.2±26.4) ml, respectively, while were (115.6±16.8) min, ( 61.7±20.7) ml in group B. There was no statistically significant in operation time between two groups(>0.05);intraoperative blood loss in group B was larger than group A(<0.05). The preoperative and postoperative 1 and 12 months, cervical curvature and Cobb angle of cervical fusion segment in group A were (11.28±1.40)°, (17.56±1.90)°, (16.64±1.80)° and (4.93±4.20) °, (9.44±2.60)°, (9.25±2.80)°, respectively, and in group B were (10.59± 1.20)°, (16.26±2.10)°, (15.76±2.50)° and (4.75±3.90)°, (7.98±2.10)°, (7.79±3.00)°. The cervical curvature and Cobb angle in all cervical fusion segments at 1, 12 months after surgery were obviously improved, and group A recovered more significantly than group B (<0.05). The JOA scores in group A were 9.46±1.70, 11.56±1.40, 14.86±1.20 before operation and 1 and 12 months after operation, and group B were 9.11±1.50, 11.40±1.30, 15.12±1.60, respectively. The postoperative JOA scores of the two groups were significantly improved (<0.05), and there was no statistically significant difference between two groups at the same time (>0.05). At the final follow up, in group A, dysphagia occurred in 2 cases, cage displacement in 1 case, and no titanium plate screw loose was found;and in group B, dysphagia occurred in 4 cases, titanium mesh collapse in 2 cases, titanium plate screw loose in 1 case. CONCLUSION Two types of anterior cervical decompression and fusion for the treatment of two segment cervical spondylotic myelopathy can effectively decompress and improve the Cobb angle and cervical curvature of the affected vertebra. The ACDF surgical procedure can directly removethe compressive thing at intervertebral level, which will lead to little vertebral body damage and favorably recovered cervical curvature. The ACCF surgical procedure has a large operation space, which can easily remove the posterior vertebral osteophyte and the calcified posterior longitudinal ligament. Long-term follow-up shows that ACDF and ACCF have good surgical procedures, mature technology, and close efficacy.
