Objective To study the relationship and clinical significance of the serum level of Pro-gastrinreleasing peptide31-98 (ProGRP)and bronchoalveolar lavage fluid for small cell lung cancer of different TNM staging.Methods 96 cases of SCLC with definite pathohistological typing were divided into stage Ⅰ～Ⅱ SCLC group (n=30),stage ⅢSCLC group (n=31),stage IVSCLC group (n=35),and the benign cases (n=90)were taken as control.Using enzyme-linked immunoserbent assay ( ELISA),the serum levels of ProGRP and bronchoalveolar layage fluid of all patients were detected,meanwhile the neuronspecific enolase were served as controls.The relation between serum and bronchoalveolar lavage fluid ProGRP level and small cell lung cancer of different TNM staging was analyzed.Results The serum level of ProGRP in stage Ⅰ～Ⅱ SCLC group,stage Ⅲ SCLC group,stage Ⅳ SCLC group,and the benign group were (295.33±118.56),(421.13±196.66),(758.76±326.19)and (29.68±16.32)μg/mol,respectively (P＜0.01 ).The level in bronchoalveolar lavage fluid ProGRP were ( 516.67 ±208.45),( 1170.55±414.65 ),( 1739.12±696.08 )and (49.23±22.50)μg/mol,respectively (P＜0.01 ).The serum level of NSE in stage Ⅰ～Ⅱ SCLC group,stage Ⅲ SCLC group,stage Ⅳ SCLC group,and the benign group were (10.36±6.76),(24.19±10.88 ),(35.76±17.30)and (9.70 ±5.28)mg/mol.The level in bronchoalveolar lavage fluid NSE were (16.66±11.62),(45.47±20.74),(65.18±29.87)and (9.70±5.28)mg/mol,respectively (P＜0.01).The positive rate of serum ProGRP in stage Ⅰ～Ⅱ SCLC group,stage Ⅲ SCLC group,stage Ⅳ SCLC group,and the benign group were 0.6000,0.7097,0.8286 and 0.0667 ,respectively(P＜0.01).The positive rate in bronchoalveolar lavage fluid ProGRP were 0.6333,0.7419,0.8571 and 0.0444,respectively (P＜0.01).The positive rate of serum NSE in stage Ⅰ～Ⅱ SCLC group,stage Ⅲ SCLC group ,stage Ⅳ SCLC group,and the benign group were 0.2333,0.6774,0.8000 and 0.2222.The positive rate in bronchoalveolar lavage fluid NSE were 0.2667,0.7097,0.8286 and 0.2667 ,respectively(P＜0.01 ).Both the ProGRP level and positive rate in serum and bronchoalveolar lavage fluid were obviously higher in stage Ⅰ～Ⅱ,Ⅲ,and Ⅳ SCLC group than in benign group (P＜0.01 ),both the ProGRP and NSE level and positive rate in bronchoalveolar lavage fluid were obviously higher than that in the serum.The positive rate in serum and bronchoalveolar lavage fluid ProGRP in stage Ⅰ～Ⅱ SCLC group were obviously higher than that in the NSE (P＜0.01),but there was no significant difference in stage Ⅲ and Ⅳ SCLC group.Conclusion ProGRP level in serum and bronchoalveolar lavage fluid have great value to the diagnosis and clinical stages of SCLC,especially the early diagnosis,ProGRP is better than NSE;As to the diagnosis of small cell lung cancer of different TNM staging,ProGRP detection in bronchoalveolar lavage fluid is better than in serum.

OBJECTIVE: To study effects of postoperative regular training of core muscle strength guided by the concept of enhanced recovery after surgery (ERAS) on the rehabilitation of elderly patients with osteoporotic lumbar vertebral compression fracture after vertebroplasty (PVP) and kyphoplasty(PKP). METHODS: Ninety-four elderly patients with osteoporotic lumbar compression fractures who underwent PKP or PVP from January 2016 to January 2018 and met inclusion criteria were divided into observation group and control group. All the patients were treated with routine anti osteoporosis therapy after operation. There were 47 patients in the observationgroup, including 18 males and 29 females, with an average age of (62.62±3.21) years old;in the control group, there were 47 cases, including 17 males and 30 females, with an average age of (62.38±2.84) years old. The patients in the control group were trained by traditional way, and the patients in observation group were instructed to conduct regular training of core muscle strength according to ERAS concept. The patients were followed up for 1, 3 and 6 months after operation. Patients' conditions were quantitatively evaluated according to Barthel scale, JOA low back pain score and Oswestry Disability Index, and the differences in treatment effects between two groups were statistically analyzed and compared. RESULTS: All the patients were followed up, and the Barthel scale, JOA low back pain score and Oswestry Disability Index score of the observation group were all better than those of the control group on the 1st and the 3rd months after surgery( CONCLUSION Early regular core strength training has a positive effect on early functional recovery and improvement of life ability after PKP or PVP for elderly patients with osteoporotic lumbar compression fractures, which is in line with the concept of accelerated rehabilitation surgery.

OBJECTIVE: By comparing the clinical efficacy of short-segment and long-segment fixation for single-segment thoracic and lumbar spine III stage Kümmell disease to explore a more suitable fixed segment for the disease. METHODS: The clinical data of 46 patients with single-segment thoracic and lumbar spine III stage Kümmell disease treated from July 2013 to December 2016 were retrospectively analyzed. Forty-six patients were divided into short-segment fixation group(one vertebra above and below the diseased vertebra) and long-segment fixation group(two vertebrae on the upper and lower of the diseased vertebra) according to different methods of cement stick fixation. There were 25 patients in the short-segment fixation group, including 9 males and 16 females, with an average age of (75.3±4.5) years old, lumbar spine bone mineral density T-value of (-3.1±0.3) g/cm³, follow-up time of (13.0±2.3) months; there were 21 patients in long-segment fixation group, 6 males and 15 females, with an average age of (74.5±3.9) years old, lumbar spine bone mineral density T-value of (-3.2±0.3) g/cm³, follow-up time of (14.7±3.6) months.The gender, age, follow-up time, operation time, intraoperative blood loss, cement leakage, and the rate of adjacent vertebrae fractures were compared between two groups, as well as pain VAS score, ODI, and kyphosis angle before and after surgery. RESULTS: There were no significant differences in age, gender, bone density, pain VAS score, ODI, and kyphosis between two groups before surgery. The operation time and intraoperative blood loss of short-segment fixation group were less than that of long-segment fixation group. The pain VAS score, ODI and kyphosis of the two groups were significantly improved at 7 days after the operation and at the latest follow-up, there was no significant difference between two groups. There were no significant differences in bone cement leakage(9/25 vs 11/21) and adjacent vertebrae fractures(4/25 vs 3/21). CONCLUSIONS Both long-segment fixation and short-segment fixation can effectively relieve pain, correct kyphosis, improve functional index, and achieve better clinical results, but short-segment fixation has less operation time and less intraoperative blood. So single-segment thoracic and lumbar spine III stage Kümmell disease does not need to extend the fixed segment, short-segment fixation is more in line with clinical needs and worthy of further study.

OBJECTIVE: From the perspective of clinical application to analyze the effectiveness and reliability of CPC/PMMA bone cement in percutaneous kyphoplasty (PKP) for the treatment of elderly patients with osteoporotic thoracolumbar fractures. METHODS: A retrospective analysis was performed on 62 patients with osteoporotic compression fracture of single-vertebral thoracic or lumbar segment who underwent PKP surgery and had a bone density less than or equal to -3.0 SD from February 2016 to December 2016. Among them, 23 patients were in CPC/PMMA group, with an average age of (77.6±2.2) years old, 39 patients in PMMA group, with an average age of (77.1±1.1) years old. The indexes between two groups were compared, including the visual analogue scale (VAS), height ratio of anterior vertebra (AVHR), local Cobb angle, cement leakage, new adjacent vertebral fracture(NAVF). RESULTS: There were no significant difference in gender, age, follow-up time and preoperative VAS, AVHR, local Cobb angle between two groups (>0.05), at the 1 day after operation, VAS, AVHR, local Cobb angle in all patients got obvious improvement (<0.05), which was no significant difference at 1 day after operation and final follow-up (>0.05). At the same time, there was no statistically significant difference in the incidence of new adjacent vertebral fracture and cement leakage (>0.05). The pain in both groups continued to improve at follow up after operation (<0.05), the local Cobb angle increased (<0.05) and AVHR decreased slightly (<0.05). However, the images of conventional methods (X-ray or CT) could not find signs about CPC degeneration and new bone ingrowth. CONCLUSION CPC/PMMA composite bone cement is safe and reliablein PKP for treatment of elderly patients with osteoporotic thoracolumbar fractures, which can effectively relieve pain and maintain vertebral body stability. It has the same curative effect as PMMA bone cement. It was worthy to research more in future, although no direct evidences support the CPC/PMMA composite bone cement can reduce the incidence of adjacent vertebral fracture, CPC degeneration or new bone ingrowth.
