Objective To observe the clinical effect of Sangpa Zhike decoction in the treatment of acute exacerbations of chronic bronchitis. Methods 180 patients with acute exacerbation of chronic bronchitis admitted to Autonomous Prefecture Hospital of traditional Chinese medicine(TCM)in Changji,Xinjiang,from August 2012 to August 2013 were enrolled. They were divided into Sangpa Zhike decoction treatment group and western medicine treatment control group by random number table,90 cases in each group. General treatments were given to the two groups. In the Sangpa Zhike decoction treatment group,additionally only oral Sangpa Zhike decoction was given(composition:Morus alba 10 g,loquat leaf 10 g,Houttuynia 10 g,honey aster 15 g,honey coltsfoot flower 6 g,Zhejiang Fritillaria 12 g,perilla 10 g,white mustard seed 6 g,Platycodon grandiflorum 10 g,Rhizoma Cynanchi Stauntonii 12 g,tangerine peel 6 g,Stemona 6 g). The ingredients were mixed in water and boiled to form a decoction,one dose daily,divided into two parts to be taken twice a day. In the western medicine treatment group,the infection was controlled by western medicine and the drugs to eliminate cough and phlegm,etc were used. The therapeutic course in both groups was 7 days. The therapeutic effect for treatment of TCM syndromes and the cough quantized integration score in the two groups were observed after treatment. Results The cure rate of Sangpa Zhike decoction treatment group was significantly higher than that of western medicine treatment control group〔70.00%(63/90)vs. 33.33%(30/90),P<0.01〕. Before treatment,the cough symptom quantization integral scores in the two groups had no statistically significance, but after treatment,the scores in the two groups were significantly lower than those before treatment. And the score in Sangpa Zhike decoction treatment group was decreased more significantly (1.66±1.12 vs. 4.36±2.32, P<0.01). Conclusion Sangpa Zhike Decoction has obvious curative effect in the treatment of acute attack of chronic bronchitis.

Objective To evaluate the mechanical stability of alternative reconstruction methods after total en bloc spon?dylectomy in the lower lumbar spine. Methods Eight adult fresh cadaveric lumbosacral spines (L1-S1) were adopted. Total en bloc spondylecotmy of the L4 vertebra was performed after intact testing. Four designed reconstruction samples were tested for the range of motion (ROM) of the spine:1) expandable artificial vertebral body and short posterior instrumentation at L3-L5 (SP), 2) ex?pandable artificial vertebral body and short posterior instrumentation with additional anterolateral fixation at L 3-L5 (ASP), 3) ex?pandable artificial vertebral body and multilevel posterior instrumentation at L2-S1 (MP), 4) expandable artificial vertebral body and multilevel posterior instrumentation with additional anterolateral fixation at L2-S1 (AMP). Nondestructive biomechanical test?ing was performed on each construct under loading control. The ROM for each construct was obtained by applying pure moments in flexion, extension, lateral bending, and axial rotation. Results In flexion, extension and lateral bending, the ROM of all the re?constructed constructs significantly decreased compared to the intact. The ROM of specimens with anterolateral fixation was less when compared to the ones without additional fixation. In lateral bending, MP (L:1.87° ± 0.32° , R:1.97° ± 0.33° ), ASP (L:1.89° ± 0.37°, R:2.08°±0.36°) and AMP (L:1.32°±0.29°, R:1.61°±0.33°) provided significantly less ROM than the SP (L:3.14°±0.35°, R:3.44°±0.34°). In axial rotation, the ROM of ASP (L:4.21°±0.58°, R:4.02°±0.59°) and AMP (L:3.56°±0.55°, R:3.52°±0.48°) was significant decreased when compared to the intact state (L: 7.47° ± 1.00° , R:7.57° ± 0.84° ). MP (L:6.33° ± 0.71° , R:5.88° ± 0.62°), ASP and AMP showed significantly less ROM than the short posterior fixation (L:9.28°±1.01°, R:9.48°±0.98°). AMP sig?nificantly decreased the ROM compared to MP. Conclusion After total en bloc spondylectomy of lower lumbar, long segmental fixation provided more stability to the construct than the short one. Compared to posterior fixation, circumferential fixations showed a higher stability. In contrast, multilevel segmental instrumentation with circumferential fixation did not provided more stability than the short constructs.

Objective To investigate procedure and therapeutic effect of resection and reconstruction for axis tumors through the sub mandible approach. Methods Between December 2004 to June 2010,17 patients with axis neoplasm underwent tumor resection and antero-posterior reconstruction through the combined the sub mandible-inner sternocleidomastoid muscle (SMIS) approach and posterior approach. Tumor lesions involved C2 in 11 cases, C2-3 in 4, C2-4 in 2. Eight cases involved vertebral body, and 9 involved both vertebral body and element. Fourteen primary lesions including 4 giant cell tumors, 4 plasmocytomas, 2 chordomas, 2 eosinophilic granulomas, 1 hemangiopericytomas and 1 lymphoma, and 3 metastatic lesions were involved in this study. Three types of reconstruction in upper cervical spine including titanium mesh plus vertically placed titanium plate, titanium mesh plus obliquely placed titanium plate and trimmed titanium mesh alone, were adopted after anterior tumor resection, and then posterior tumor resection and reconstruction were performed. Results All patients experienced pain relief and neurological improvement after surgery. Except for one incidence of screw pull-out which was corrected by a revision surgery, solid fusion was achieved in all patients. A follow-up period of 6 months to 6 years was available for this study. One patient died of cerebral infarction 9 months postoperative. Two patients with chordoma relapsed 13 months and18 months postoperative, respectively, of whom one died of high plegia and respiratory failure, and the other was alive with disease. Two patients with metastasis died of multiple remote metastases 12 months and 18 months postoperative, respectively. Conclusion Through the SMIS apporach, a satisfactory exposure can be obtained for axis tumor resection and reconstruction. Anterior reconstruction of upper cervical spine after tumor resection can be achieved with internal fixation system of cervical spine, which can improve intraopera-tive safety. The combined anterior reconstruction and posterior occipito-cervcial fixation can provide immediate stability, and benefit maintaining stability of upper cervical spine.

Objective To investigate the safety and feasibility of en-bloc resection of a primary sacral chordona based on a 3-dimensional printing model.Methods 31 patients with primary sacral chordoma underwent en-bloc resection via a onestage posterior approach or combined anterior and posterior approaches in our oncology department from January 2013 to December 2014.They comprised 21 males and 10 females of mean age (49.2±12.5) years (range,26-67 years).Preoperative 3-D printing models were created by 3D printing technology,it included tumor tissue,the around vascular and nerves involved in sacral chordoma.The sacral chordomas were en-bloc resection with decompression and internal fixation.Results With the mean (29.0±6.8)months follow-up (range from 19 to 41),all patients underwent en bloc excision via 26 cases with posterior approach,5 cases combined posterior and anterior approaches in one stage.The mean operative time and estimated blood loss were (275.0±58.1) min and (3 250.0±1 304.4) ml,respectively.The visual analogue scale (VAS) score was (5.6±1.9) in average (range from 3 to 9) at preoperation,and (2.0±1.5) at post-operation,which was significantly lower than that of preoperation,and the pain was relief obviously.There were 13 cases in grade C,11 cases in grade D,7 cases in grade E of American Spinal Injury Association (ASIA) grade neurological function before surgery,compared with the pre-operation,there were 5 cases in grade C,6 cases in grade D,20 cases in grade E of post-operation,which was significantly improved.MSTS (Musculoskeletal Tumor Society) 93 score was 6-29 points (20.0％-96.7％) at the follow-up 3 months after surgery,with the average of (19.8 ± 5.8) points,which excellent in 8 cases,good in 14 cases,general in 5 cases,poor in 4 cases.Two cases of dysporia for the reasons of resecting on one side of the S1,2 nerve roots involved by the sacral chordoma,after sacrificing the nerve root of complete tumor resection,the urine left dysfunctional,while the pain of other 29 patients were thoroughly relief after surgery.The ones were relieved with the disturbance of sensation of the perineum before the operation.2 cases were recovery of leakage of cerebrospinal by the drainage of lumbar cistern with normal temperature.One hypostatic pneumonia patient was cured by anti-inflammatory.One with the urinary infection got better by the effective bladder irrigation,which had diabetics mellitus with the bladder stoma before.1 case of skin necrosis due to vascular thrombosis before operation,recevied flap translocation half month after surgery,got recovery 3 months later.Only one underwent tumor resection for the recurrence at 15 months follow-up.Conclusion It is feasible and safe to perform en bloc resection of primary sacral chordoma.This is the most effective means of managing method of the marginal resection of the tumor.Preoperative 3-D printing modeling enables better anatomical understanding of the relationship between the tumor,and can avoid vascular and nerves tissue injury,which can also assist in planning the surgical procedure,and be worth recommendation.

Objective: To study the mechanism of Heshi-Gejiugao on the nerve endocrine immune network in the treatment of perimenopausal syndrome. Methods: A total of 100 patients with perimenopausal syndrome were randomly divided into treatment group and control group, 50 cases in each group. The control group was only given general treatment, while the treatment group was treated with Heshi-Gejiugao on the basis of general treatment for 30 days. The clinical efficacy, Kupperman score, nerve, endocrine and immune related indexes of the two groups before and after treatment were observed. Results: The total effective rate was 96.0% (48/50) in the treatment group and 50.0% (25/50) in the control group. There was significant difference between the two groups (χ²=37.639, P<0.01). The Kupperman score (17.52 ± 2.73 vs. 24.22 ± 6.87, t=6.409) in the treatment group was significantly lower than that in the control group (P<0.01). After treatment, NE (1 878.08 ± 931.57 ng/m vs. 1 278.43 ± 866.32 ng/ml, t=3.331), DA (1 568.56 ± 597.15 ng/ml vs. 1 183.62 ± 798.72 ng/ml, t=2.729) in the treatment group were significantly higher than those in the control group (P<0.05); E₂ (42.12 ± 9.77 pg/ml vs. 35.91 ± 12.55 pg/ml, t=2.761), FSH (62.70 ± 15.96 mIU/ml vs. 72.67 ± 30.18 mIU/ml, t=2.065), LH (33.88 ± 12.18 mIU/ml vs. 42.93 ± 9.83 mIU/ml, t=4.089) were significantly lower than those of the control group (P<0.05). CD3⁺ (1 087.34/μl ± 432.19/μl vs. 918.27/μl ± 199.72/μl, t=2.511), CD4⁺ (738.16/μl ± 326.75/μl vs. 588.43/μl ± 212.55/μl, t=2.716) and CD4/CD8 (1.87 ± 0.56 vs. 1.16 ± 0.55), t=6.483) were significantly higher than those of the control group (P<0.05); CD8⁺ (788.32/μl ± 214.56/μl vs. 976.37/μl ± 318.62/μl, t=3.462) was significantly lower than that of the control group (P<0.05). Conclusions Heshi-Gejiugao can reduce the symptoms and improve the quality of life by regulating the multi target and multi direction of the neuroendocrine immune network of perimenopausal patients.

Objective To study the feasibility and safety of total en bloc spondylectomy (TES) for bone tumors of the fourth lumbar spine and evaluate the clinical outcomes.Methods From March 2011 to December 2013,21 patients undergone total en bloc spondylectomy in posterior-only approach were retrospectively reviewed.The patients included 9 males and 12 females,with a mean age of 47.1± 15.6 years old (range,15-71 years old).This series included 12 cases of primary bone tumors and 9 cases of solitary metastases.Preoperative evaluation according to clinical,imaging and pathologic features was performed meticulously to select patients.The length of surgery,estimated blood loss,surgical margins,instrumentation failure,perioperative complications,Frankel scale,visual analogue scale (VAS) for pain,local control rate and overall survival were reviewed and analyzed.Results Total en bloc spondylectomy was performed successfully in all patients.Average operative time and estimated blood loss were 297.6±44.6 min (range,225-420 min) and 2 247.1±904.5 ml (range,900-4100 ml),respectively.The mean follow-up time was 50.4± 17.1 mons (range,24-79 mons).All patients encountered nerve roots stretch and 5 patients (23.8％) showed lower extremeties neurological dysfunction.All of them improved in 2-4 weeks postoperatively and recovered completely at 6-month follow -up.Cerebrospinal fluid leak was found in 4 patients (19.0％).The VAS score was 1.5±1.4 at post-operation,which was significantly lower than the 6.2± 1.6 in average at operation (P=0.008).Three patients with metastatic tumors died during the follow-up.Titanium mesh cage subsidence was observed in 7 patients (33.3％).No implant failure was occurred during the follow-up.Conclusion Total en bloc spondylectomy for tumors of the fourth lumbar spine in a posterior-only approach is feasible.However,there are many intraoperative neurological complications and the indications for TES are extremely limited.

Objective:To propose and verify a surgical classification system for the axial primary malignant and aggressive benign tumor.Methods:The CZH surgical classification system was originally developed for the axial primary malignant and aggressive benign tumor. The CZH surgical classification system includes seven types, according to the anatomic features and the extension of tumor violation. A total of 136 patients (79 males and 57 females) with axial primary malignant and aggressive benign tumor from multiple tertiary centers who received surgery from July 2006 to July 2019 were included. The average age was 44.40±17.55 years (8-83 years) old. There were 99 malignant tumors and 37 aggressive benign tumors included. The number of patients with each classification was presented as followed, Type I 13, Type II 15, Type IIIa 3, Type IIIb 20, Type IVa 43, Type IVb 12, Type Va 21, Type Vb 3, Type VI 2, Type VIIa 3 and Type VIIb 1. Surgical procedures were selected according to different types in classification. The inter- and intra-observer consistencies were evaluated by the Kendall's W test. The VAS, Frankel score, overall survival and recurrence free survival were recorded during the follow-up. Results:The inter- and intra-observer consistent coefficient was 0.973 and 0.996, respectively ( P<0.05). The single posterior approach was adopted for the Type II tumors. Other patients underwent surgery by the combined antero-posterior approach. The majority in anterior approach (113 cases) was the modified submandibular approach. The reconstruction modes included anterior "T" shape titanium mesh (112 cases) or the 3D printed prothesis (7 cases) combined with the posterior occipto-cervical fusion (92 cases) or the pedicle screw system (44 cases). The average surgical duration and the volume of intraoperative bleeding was 348.40±136.14 min (60-760 min) and 1 225.69±859.40 ml (80-4 000 ml), respectively. The operation duration and volume of intraoperative bleeding among each type were with statistical difference. The patients with Type IV, V tumors had longer operation duration than those with Type II tumors. Those with Type V and VII tumors had longer operation duration than those with Type I tumors. The patients with Type V tumors had more intraoperative bleeding than those with Type I-IV tumors. The average preoperative VAS score was 4.15±2.25 and then was reduced significantly to 0.62±0.71 and 0.38±0.59 at one and three months after operation, respectively. The Frankel score was also significantly ameliorated at one and three months postoperatively. There were 22 postoperative complications (16.2%). The complications included cerebral spinal fluid leak (12.5%), dysphagia and/or dysphonia (7.4%), dyspnea (5.1%), wound infection (3.7%), wound hemorrhage (2.2%) and pharyngeal dehiscence (1.5%). The incidence of postoperative complication was 25.9% in Type IV-VII tumors, while 11.8% in Type I-III tumors. Conclusion:CZH surgical classification system was verified with high observer consistency. This classification system could assist surgeons to select proper surgical approaches, resection modes and reconstruction modes, and thus ensure the safety of surgery and reduce the recurrence. The tumors in Type IV, V and VII may be with more challenging for surgeons. The incidence of postoperative complication in Type IV-VII tumors may be higher than that in Type I-III tumors.

Objective: To analyze the epidemiological and clinical characteristics of patients with 2019 novel coronavirus (2019-nCoV) infection in Shenyang. Methods: The epidemiological and clinical characteristics of 30 patients diagnosed with 2019-nCoV infection admitted to Shenyang sixth people's hospital on January 22, 2020 and February 8, 2020 were retrospectively analyzed. Results: Among the 30 cases, 21 were imported, including 17 from Hubei Province and four from other provinces. Nine cases were local infections. There were 18 men and 12 women, aging from 21 to 72 years with the median of 43 years. Eight cases had underlying diseases including hypertension, diabetes, coronary heart disease and bronchitis. On admission, two (7%) cases were mild, 19 (63%) cases were ordinary, eight (27%) cases were severe, and one (3%) case was critical. Clinical manifestations mainly include fever, with or without upper respiratory tract symptoms, normal, decreased or slightly increased white blood cell counts, mainly decreased lymphocyte counts, normal or increased c-reactive protein, and normal procalcitonin. The computed tomography (CT) of the early stage of the lungs showed that multiple patchy ground glass shadows were mainly accompanied by consolidation, which often involved both lungs or multiple lobes of one lung. At the moment, the clinical treatment mainly included respiratory support, symptomatic treatment, antiviral treatment adn anti-bacterial treatment. By February 15, a total of nine cases were cured and discharged, including one mild case, six ordinary cases, and two severe cases. In the comparisons between mild/ordinary patients and severe/critical patients, the fever duration in the severe/critical group (median 11.5 d) was significantly longer than that in the light/normal group (median 2 d) (Z=-2.292, P=0.022), and the laboratory tests indicated elevated d-dimer levels (Z=-2.669, P=0.008) and more cases with neutrophilic/lymphocyte ratio > 3 (Z=-4.071, P<0.01). Conclusions In Shenyang, the early cases with 2019-nCoV infection are mainly imported cases, and expanding local infections gradually develop. Clinical manifestations are mainly characterized by fever and cough. Lung CT performance shows multiple ground glass shadows, mainly accompanied by consolidation. CT changes in the lungs should be closely monitored during the treatment, and CT findings in the lungs may change earlier than the clinical manifestations. Prolonged fever duration, elevated d-dimer level and neutrophil/lymphocyte ratio >3 could be used as early warning indicators for severe cases.

The adjacent anatomy of the pelvis is complicated, with digestive, urinary, reproductive and other organs as well as important blood vessels and nerves. Therefore, accurate resection of pelvic tumors and precise reconstruction of defects after resection are extremely difficult. The development of medical 3D printing technology provides new ideas for precise resection and personalized reconstruction of pelvic tumors. The “triune” application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis in pelvic tumor limb salvage reconstruction treatment has achieved good clinical results. However, the current lack of normative guidance standards such as preparation and application of 3D printing personalized lesion model, osteotomy guide plate and reconstruction prosthesis restricts its promotion and application. The formulation of this consensus provides normative guidance for 3D printing personalized pelvic tumor limb salvage reconstruction treatment.
