OBJECTIVE: To investigate the clinical effect of aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban for lower extremity venous thrombosis after total knee arthroplasty and the influence on hypercoagulation. METHODS: Seventy-three patients of knee osteoarthritis with lower extremity venous thrombosis after total knee arthroplasty (KOA) were randomly divided into an observation group (37 cases, 2 cases dropped off) and a control group (36 cases, 1 case dropped off). The patients in the control group took orally rivaroxaban tablets, 10 mg a time, once a day. On the basis of the treatment as the control group, the aconite-isolated moxibustion was applied to Yongquan (KI 1) for the patients of the observation group, once daily and 3 moxa cones were used in each treatment. The duration of treatment was 14 days in both groups. Before treatment and 14 days into treatment, the ultrasonic B test was adopted to determine the conditions of lower extremity venous thrombosis in the two groups. Before treatment, 7 and 14 days into treatment, the coagulation indexes (platelet [PLT], prothrombin time [PT], activated partial prothrombin time [APTT], fibrinogen [Fib] and D-dimer[D-D]), the blood flow velocity of the deep femoral vein and the circumference of the affected side were compared between the two groups separately, and the clinical effect was evaluated. RESULTS: Fourteen days into treatment, the venous thrombosis of the lower extremity was relieved in both groups (P<0.05), and that of the observation group was better than the control group (P<0.05). Seven days into treatment, the blood flow velocity of the deep femoral vein was increased compared with that before treatment in the observation group (P<0.05), and the blood flow rate in the observation group was higher than that in the control group (P<0.05). Fourteen days into treatment, PT, APTT and the blood flow velocity of the deep femoral vein were increased in the two groups compared with those before treatment (P<0.05); and PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all reduced in the two groups (P<0.05). Compared with the control group 14 days into treatment, the blood flow velocity of the deep femoral vein was higher (P<0.05), PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all lower in the observation group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 85.7% (30/35) in the control group (P<0.05). CONCLUSION Aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban can effectively treat lower extremity venous thrombosis after total knee arthroplasty, relieve hypercoagulation, accelerate the blood flow velocity and alleviate swelling of the lower extremity in the patients with knee osteoarthritis.

Objective: To explore the surgical methods and clinical outcomes of severe angular kyphosis with the length of the spinal cord constant in the osteotomy area. Methods: Clinical data from 20 patients with severe angular kyphosis who underwent surgical treatment from January 2017 to December 2020 in the Department of Spinal Surgery,Hangzhou Xiaoshan District Hospital of Traditional Chinese Medicine were retrospectively analyzed. There were 11 males and 9 females, aged (28.5±8.9) years (range:17 to 46 years).There were 15 cases with congenital angular kyphosis,5 cases with tuberculous angular kyphosis.The angle of kyphosis was (107.1±12.9)° (range:93.2° to 131.4°).Frankel classification:2 cases with grade B,4 cases with grade C,3 cases with grade D.The kyphotic vertex is located at the T₉ to T₁₂ segments.Pedicle screws were placed in 3 or 4 adjacent segments at the proximal and distal kyphosis apex of the patients using a surgical navigation system.Piezosurgery combined with a grinding drill was used to complete the osteotomy in the apical vertebral region.Titanium mesh or artificial vertebral body was implanted,and the osteotomy surface was closed using this as the fulcrum to complete osteotomy.Spinal X-ray examination was performed before surgery,immediately after surgery and at the last follow-up,and sagittal and coronal Cobb angle,sagittal and coronary balance parameters,anterior vertebral height,posterior vertebral height,and spinal cord length were measured.Pulmonary function,visual analogue scale (VAS),and Oswestry's disability index (ODI) were collected and estimated before and after treatment.The analysis of variance of repeated measurement data was used for each evaluation index before and after treatment,and the t test was used for pairwise comparison. Results: All patients successfully completed surgery,with artificial vertebral body in 11 cases and double titanium mesh in 9 cases.The follow-up time was (28.2±2.3) months (range:26 to 31 months).Sagittal vertical axis improved from (46.9±13.7)mm(range:21.7 to 75.7 mm) before surgery to (10.7±5.5)mm (range:3.6 to 28.1 mm) after surgery,and (11.0±5.7)mm(range:3.6 to 29.3 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The mean kyphotic Cobb angle was corrected from (107.1±12.9) ° (range:93.2 ° to 131.4°) before surgery to (30.6±8.5) ° (range:20.0 ° to 47.8 °) after surgery (all P<0.01),and (32.1±8.7) ° (range:18.2 ° to 50.8°) at the last follow-up,the differences were statistically significant compared to before surgery(all P<0.01).The anterior vertebral height improved from (14.2±2.9)mm(range:11.04 to 23.6 mm) before surgery to (45.3±7.5)mm(range:29.4 to 56.5 mm) after surgery,and (44.3±6.8)mm(range:29.6 to 56.0 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The posterior vertebral height was improved from (51.8±5.3)mm (range:43.1 to 61.4 mm)before surgery to (57.6±4.7)mm (range:45.7 to 64.1 mm)after surgery,and (56.3±5.0) mm (range:49.7 to 68.5 mm) at the last follow-up,the differences were statistically significant compared to before surgery (all P<0.01).The spinal cord length of the osteotomy segment was (73.1±12.0)mm (range:56.8 to 98.4 mm) before surgery and (74.8±12.8)mm (range:53.5 to 100.2 mm) after surgery and (75.2±13.7)mm (range:53.9 to 102.4 mm) at the last follow-up,the difference was not statistically significant among them(F=0.144,P=0.866).The ODI and VAS scores improved significantly after surgery and at the last follow-up,and the differences were statistically significant (all P<0.01). Conclusion: The posterior vertebral column resection technique combined with titanium mesh or an artificial vertebral body implant for the treatment of severe angular kyphosis can significantly improve the kyphosis,neurological function,and life quality of patients without affecting the length of the spinal cord.

Anterior cervical fusion surgery is the first choice for spine surgeons in the treatment of cervical spine diseases. It has significant effects in treating cervical degenerative diseases, trauma and tumors and other cervical diseases. In anterior cervical fusion, it is necessary to use a distractor to properly distract the intervertebral space, so as to fully expose and relieve the compressive factors, restore the physiological height, curvature and stability of the lesion segment, and achieve the best surgical effect. However, there is currently no consensus on the standard distraction height for the intervertebral space during anterior cervical surgery. This article reviewsed the progress of intervertebral space height in anterior cervical fusion from three dimensions:the relationship between intervertebral space height and cervical disc degeneration mechanism, the selection of intervertebral space height during operation, the recovery of intervertebral space height and the postoperative effect, so as to provide theoretical basis and reference for spinal surgeons when performing intervertebral distraction during operation.

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.

OBJECTIVE: To explore the safety and effectivity of ultrasonic bone knife in osteotomy of degenerative kyphosis. METHODS: The clinical data of 32 patients with degenerative kyphosis treated from February 2014 to May 2016 were retrospectively analyzed. There were 12 males and 20 females, aged 50 to 71 years with an average of (62.1±12.3) years. Preoperative Cobb angle was 25.3° to 36.7° with an average of (28.6±10.2) °. All patients underwent multi-segment Ponte osteotomy combined with posterior long segmental internal fixation. According to different osteotomy tools, the patients were divided into traditional tool group (group A, 18 cases) and ultrasonic bone knife group (group B, 14 cases). The operation time, laminectomy time, number of osteotomy segments, intraoperative blood loss, postoperative drainage, hospitalization time and postoperative complications were recorded.Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate clinical outcomes before and 1 month after surgery. RESULTS: All the patients were followed up from 8 to 24 months with an average of 16.4 months. There were no significant differences in operative time and hospitalization time between two groups (>0.05). Intraoperative single laminectomy time of group A was more than that of group B (<0.05). The number of osteotomy segments in group A was less than that in group B (<0.05). Intraoperative blood loss and postoperative drainage in group A were more than that in group B (<0.05). There were no significant differences in VAS and ODI between two groups (>0.05). There were no dural, nerve and spinal cord injuries in both groups, and there were no complications such as improper operation of the instrument and nonunion of the osteotomy. CONCLUSION The use of ultrasonic bone knife for Ponte osteotomy is safe and effective. It can effectively save the time of single laminectomy while reducing the amount of intraoperative blood loss and postoperative drainage. The safety and clinical efficacy of ultrasonic bone knife are no less than traditional tools.

Objective:To investigate the related risk factors for biliary anastomotic stenosis after liver transplantation (LT) from donation after cardiac death(DCD) and therapeutic strategies.Methods:The data of 192 patients who received LT from DCD in First Hospital of Kunming from Jan 2010 to Jun 2018 were retrospectively analyzed. A total of 145 patients were enrolled, 85 males and 60 females, with average age 45 years. There was a biliary anastomotic stenosis in 8 cases and no stenosis in 137 cases. Their Chinese criterion for biliary anatomic stenosis, age, body mass index, liver fat, cold/warm ischemia time, unschedule cardiac arrest time, usage of vasopressors, high sodium in the donor were compared, and stenosis related factors were analysed by Spearman correlation analysis.Results:The stenosis was positively correlated with age ( r=0.229), body mass index ( r=0.204), lipoidosis ( r=0.239), duration of hot ischemia ( r=0.214), total duration of unplanned cardiac arrest ( r=0.401), use of booster drugs ( r=0.237), and preoperative donor hypernatremia ( r=0.557) (all P<0.05). Endoscopic biliary stent implantation is effective in the treatment of biliary anastomotic stenosis and has a high success rate. Conclusions:There are many factors related to biliary anastomotic stenosis after DCD liver transplantation, but the better donor maintenance, shorten cold/ warm ischemia time, improved anastomosis will be helpful to reduce biliary complications.As the same time, endoscopic biliary stent placement is the preferred way to treat biliary anastomotic stenosis.

OBJECTIVE: To choose the disease-causing gene in a Chinese pedigree with ankylosing spondylitis (AS) by whole-exome sequencing (WES), and provide theory basis for mechanism of disease. METHODS: Clinical data of AS pedigree were collected, including 2 males, the age were 48 and 18 years old, the course of disease were 23 and 4 years. Whole blood genomic DNA of AS was extracted to perform whole exome sequencing, the results were compared with human databases, common variations which had been reported were wiped out, then non synonymous single nucleotide variants(SNVs) from the family members were combined, and candidate genes was selected initially. RESULTS: Totally 80 G data was obtained from AS family with high quality.By comparing results between patient and normal subject, and filtering with number of biological database, the result showed heterozygous mutation of JAK2 gene 12 exon c.1709 A>G (p.Tyr570Cys) may be the potential disease-causing gene. The variant c.1151T>C of MUC3A gene may be one of the causes of intestinal symptoms in the family members. CONCLUSION It is feasible to find t candidate gene mutations of AS by Exon sequencing. The mutation c.1709 A>G in gene JAK2 identified by whole exome sequencing might be the pathogenic mutation in this AS pedigree.

OBJECTIVE: To investigate the clinical outcome of single or double-segment pedicle subtraction osteotomy (PSO) for the treatment of old thoracolumbar osteoporotic compression fractures with kyphosis. METHODS: The clinical data of 26 patients with old thoracolumbar osteoporotic compression fractures with kyphosis who underwent surgery from January 2015 to June 2017 were retrospectively analyzed. There were 12 males and 14 females, aged from 58 to 72 years old with an average of 65.6 years. The time interval from fracture to surgery was (8.2±1.5) years. According to different surgical methods, the patients were divided into single-segment PSO group (group A) and double-segment PSO group(groupB). The perioperative data, preoperative and postoperative imaging data and postoperative complications were recorded, and the Oswestry Disability Index (ODI) and visual analogue scale (VAS) were used before and after surgery to evaluate the clinical effect. RESULTS: All patients were followed up for 6-24 months with an average of 14.5 months. There was a statistically significant difference in operation time and intraoperative blood loss between the two groups (<0.05). There was no significant difference in total drainage volume and length of hospital stay (>0.05). The postoperative correction angle of the single segment PSO group was (33.3± 9.4) ° with the correction rate of 85.3% and the double segment PSO group was (41.0±13.5) ° with the correction rate of 92.7%, and there was statistical significance between two groups (<0.05). There were no significant differences in postoperative lumbar lordosis (LL), sagittal vertical axis (SVA), and ODI, VAS between two groups (>0.05). One case of cone injury occurred in the single-segment PSO group and recovered after treatment. There were no complications of spinal cord injury in the double segment group. Loose screws occurred during surgery in three patients in the single-segment PSO group and one patient in the double-segment PSO group (<0.05). All 4 patients were re inserted with screws after using bone cement to reinforce the nail pathway. There were no complications such as anterior spinal vascular and nerve damage or osteotomy unfusion. CONCLUSION Both single-segment PSO and double-segment PSO can achieve good orthopedic and clinical effects in the treatment of old thoracolumbar osteoporotic fractures with kyphosis. For patients with correction angles greater than 40° , the double-segment PSO provides a better correction angle and is safer, but it is with longer operation time and more intraoperative bleeding.
