Different types of cervical spondylosis treated by a vartiety of operative techniques were compared with the aim at improving quality of treatment for cervical spondylosis. 1780 operations including laminectomy, open door laminoplasty, subtotoal vertebrectomy, Cloward's technique, Smith's technique, "keyhole" decompression of the intervertebral foramina, discectomy with intervertebral fusion, intervertebral fixation with titanium cage, and fixation with titanium plate. The results showed:(1)Myelopathy in 363 cases: laminectomy on 4; subtotoal vertebrectomy on 136; Cloward's technique on 201; Smith's technique on 4; intervertebral fixed with titanium on 4; discectomy with fusion on 14. 104 cases were followed up, 82 7% of them showed good and excellent recovery. (2)Myeloradiculopathy in 1106 cases: laminectomy on 3; laminoplasty on 143; subtotoal vertebrectomy on 687; Cloward's technique on 263; Smith's technique on 2; discectomy with fusion on 8. 396 cases were fouowed up, 85 6% of them showed good and excellent recovery. (3)Radiculopathy in 35 cases: posterior approach key hole decompression of the intervertebral foramina on 19; lateral approach decompression of the intervertebral foramina on 9; anterior approach decompression of the intervertebral foramina on 7. Good and excellent results reached 100%. (4)Vertebral artery compression in 9 cases: resection of the osteophyte of the uncinate processes on 5; opening of the transverse foramen on 4. The results were good. (5)Esophagus compression in 18: after removing directly the osteophyte, the symptoms disappeared. (6)Ossification of the posterior longitudinal ligament in 93 cases: subtotal vertebrectomy on 39; laminoplasty on 45; laminectomy on 9. 41 cases were followed up, good and excellent recovery was seen in 85 3%. (7)Cervical stenosis in 156 cases: laminoplasty on 149 and laminectomy on 7. Good and excellent recovery was observed in 97 5%. All the results indicated that a variety of operative techniques could be selected depending on the site of the osteophytes. Direct resection of the lesion which produced compression and fixation or fusion of vertebral bodies were both important to achieve a satisfactory result

Objective To elucidate the clinical features and treatment of hemangiopericytomas (HPCs) in different parts of the body, especially in CNS. Methods Clinical data of 41 cases with HPC which were treated at 301 Hospital from 1993 to 2004 were retrospectively analyzed with a review of relevant literature. Follow-up periods ranged from 4 to 150 months after surgery (mean 34 months). Results Among 41 patients of HPC, 21 tumors (51.2%) were found in CNS, and the rest 20 (48.8%) in other systems. Thirteen tumors were diagnosed as malignant HPC. Surgery for tumor removal was performed in all 41 patients. Among the 62 operations, total removal of tumor was achieved in 49 cases and subtotal removal in 13 cases. Recurrence in original site of the tumor occurred 21 times (33.9%) in 14 patients. Five patients (12.1%) presented one or more distant metastasis, and 5 patients died. HPCs in CNS and in other systems displayed similar clinical characteristics and pathological morphology. Conclusions HPC is a rare angioneoplasm that may arise in any part of the body. It is a great challenge to neurosurgeons as well as other surgeons to surgically manage the tumor. HPC has an unfavorable prognosis because its high rate of recurrence and metastasis. HPC in CNS and in other parts of the body should be recognized as one disease. At the same time, HPC in CNS has its distinct features.

Objective To explore the neuroprotective effects of Buchang Naoxintong Capsule on focal cerebral ischemia/reperfusion in rats.Methods Rat model of ischemic reperfusion of cerebral middle artery was established according to Zea Longa's pattern. Rats were randomly divided into pseudo-operation group, ischemia/reperfusion group and Buchang Naoxintong Capsule treated group. The ischemia/reperfusion group and Buchang Naoxintong Capsule treated group were both divided into five subgroups according to reperfusion time or administration time such as 1 d, 3 d, 7 d, 10 d and 15 d. Using immunohistochemical staining method and color image analysis, we measured the expression of vessel endothelium growth factor (VEGF) and Laminin in the region of ischemia. Pathological changes were observed with HE staining and transmission electron microscope. Besides that, the content of brain water was assayed.Results Compared with ischemia/reperfusion group, less numbers of shrinkage or swelling neurons were found in Buchang Naoxintong Capsule treated group.The content of brain water, the expression of VEGF were obviously different between Buchang Naoxintong Capsule treated group and the other two groups (all P

ObjectiveTo investigate the clinical efficacy of points Shenmai(BL62)and Zhaohai(KI6)in treating cervical vertigo. MethodSixty-eight patients meeting the diagnostic criteria were randomly allocated to treatment and controlgroups, 34 cases each. The treatment group received conventional acupuncture at heel vessel points Shenmai and Zhaohai plus cervical Huatuo jiaji points and the control group, conventional acupuncture at cervical Huatuo jiaji points alone. In the two groups, the vertigo symptom score was recorded, and the clinical therapeutic effects and pre-/post-treatment change in the score were observed.ResultThe total efficacy rate was 94.1% in the treatment group and 79.4% in the control group. The therapeutic effect was significantly better in the treatment group than in the control group (P<0.05). The vertigo symptom score decreased significantly in the two groups after the course of treatment compared with before (P<0.01). Vertigo improved significantly more inthe treatment group than in the control group (P<0.05).ConclusionAcupuncture at points Shenmai and Zhaohai is significantly effective by comparison with conventional acupuncture in clinicaltreatment of cervical vertigo.

Objective To study the relationship between breast symptom, characteristic of ultrasound image and sex hormone level in women with different menstruation status.Methods 50 women with normal men-strual cycle, 129 women in menopause transition and 318 menopausal women were recruited.Breast ultrasound were performed.Breast section thickness, ductal width, breast structure and blood flow were measured.Serum estradiol( E2 ) and progesterone( P) level were measured by enzyme immunoassay on the day when ultrasound was performed.Onset and persistent days of breast pain were recorded.Results ①32(60.4%)women with normal menstrual cycle and 74(57.4%)women in menopause transition women experienced cyclic mastalgia.The aver-age serum E2 level and serum progesterone level were higher in women with cyclic breast pain than in women with-out breast pain.12.5%of menopausal women had breast pain.There was no significant difference of average ser-um E2 level between women with cyclic breast pain and women without breast pain②Breast section thickness was (14.4 ±4.3)mm,(13.0 ±3.7)mm and(10.6 ±3.2)mm, and ductal width was(0.62 ±0.18)mm,(0.88 ± 0.39)mm and(0.90 ±0.47)mm in normal menstrual group, menopause transition group and menopausal group, respectively.The difference had statistical significance.③26 women ( 49.1%) in normal menstrual group had breast structure changes, while 42 cases ( 32.6%) and 60 cases ( 18.9%) in menopause transition group and menopausal group had breast structure changes.Conclusions Most women in normal menstruation and meno-pause transition group experience mastalgia.About 1/3 breast structure change in women of normal menstruation are inversible.About 1/2 breast structure change in menopause transition and menopausal group are similar to those with normal menstruation.

Objective To explore effects of atorvastatin on the expressions of cyclooxygenase-2(COX-2) and membrane-associated prostaglandin E2 synthase-1 (mPGES-1) in the carotid atherosclerotic plaques of rabbits.Methods Totally 33 male New Zealand white rabbits(≥ 36months of age ) were assigned into normal control group (n=8) and animal model group with carotid atherosclerotic stenosis (n =25).The rabbit models were randomly divided into non-intervention group,celecoxib treatment group (15 mg · kg-1 · d-1,twice daily) and atorvastatin treatment group (5 mg · kg-1 · d-1,once daily) (n=8 each).Four weeks after treatment,the mRNA and protein expressions of COX-2 and mPGES-1 in carotid plaques were determined by RT-PCR and Western blot,respectively.Results The mRNA expressions of COX-2 (0.97±0.09,0.44±0.05,0.60±0.04vs.0.23±0.04,F=66.77,P＜0.01) and mPGES-1 (0.92±0.07,0.41±0.04,0.61±0.03 vs.0.17±0.03,F=54.87,P＜0.01)in carotid atherosclerotic plaques were significantly higher in non intervention group,celecoxib treatment group and atorvastatin treatment group than in normal control group.The mRNA expressions of COX-2 and mPGES-1 were decreased in celecoxib treatment group and atorvastatin treatment group as compared with non-intervention group ( both P ＜ 0.01 ).The protein expressions of COX-2 (0.89±0.06,0.42±0.07,0.62±0.04 vs.0.18±0.05,F=61.75,P ＜0.01) and mPGES-1(0.91±0.05,0.44±0.05,0.63±0.05 vs.0.21±0.04,F=86.44,P＜0.01)in carotid atherosclerotic plaques in non-intervention group,celecoxib treatment group and atorvastatin treatment group were increased as compared with those in normal control group.The mRNA and protein expressions of COX-2 and mPGES-1 were decreased in celecoxib treatment group and atorvastatin treatment group as compared with non-intervention group(all P＜0.01 ).The expressions of COX-2 and mPGES-1 in carotid atherosclerotic plaques were reduced in celecoxib treatment group as compared with atorvastatin treatment group (P ＜ 0.01).Conclusions As COX-2 inhibitor celecoxib,atorvastatin may inhibit the expressions of COX-2 and mPGES-1,and interfere with the inflammatory response which plays key role in the pathological progress of carotid atherosclerotic plaques,and thus slow the progress of carotid atherosclerosis.

BACKGROUND:Tissue-engineered bone can be obtained by the combination of chondrocytes and polyglycolic acid scaffold. OBJECTIVE:To investigate the effect of alogeneic chondrocytes/polyglycolic acid scaffold compound in the repair of thyroid cartilage defects in rabbits. METHODS: Twenty New Zealand adult rabbits were randomly divided into experimental group with implantation of alogeneic chondrocytes/polyglycolic acid scaffold compound and control group with implantation of polyglycolic acid scaffold. Gross and histological observations were done at 4 and 8 weeks after implantation. RESULTS AND CONCLUSION: (1) Gross observation results: 4 weeks after surgery, cartilage defects in the experimental group were repaired certainly, and no necrosis appeared in the repair area; in the control group, the defects were filed with muscle and connective tissues. At 8 weeks after implantation, cartilage defects in the experimental group were further repaired, with unclear repair boundaries, and in the control group, cartilage defects were no repaired and showed a notable boundary with the surrounding normal cartilage tissues. (2) Immunohistochemical staining results: the expression of type II colagen in the experimental group was higher than that in the control group (P < 0.05) at 4 and 8 weeks after implantation. These findings indicate that the alogeneic chondrocytes/polyglycolic acid scaffold compound can promote the repair of thyroid cartilage defects in rabbits.

Objective To prospectively compare the clinical efficacy between high versus low viscosity bone cement in percutaneous vertebroplasty (PVP) for severe osteoporotic vertebral compression fractures (OVCF).Methods A prospective study was conducted in 61 old patients with single severe OVCF who had sought medical attention in our hospital from August 2014 to October 2015.They were randomly assigned to group H (n =30) to receive PVP using high viscosity bone cement and group L (n =31) to receive PVP using low viscosity bone cement.The 2 groups were compared preoperatively and postoperatively in terms of visual analogue scale (VAS),Oswestry disability index(ODI),short Form-36 General Health Survey(SF-36),Kyphosis cobb's angle,height of the injured vertebra,and volume and leakage of bone cement.Results Significant improvements in VAS,ODI and SF-36 score were noted after operation in both groups,but there were no significant differences between the 2 groups (P ＞ 0.05).The 2 groups made significant improvements after operation in cobb's angle and height recovery rate of the injured vertebra;improvements in group H (14.7° ± 3.4° and 28％ ± 8％) were significantly greater than in group L (16.5° ± 2.5° and 22％ ± 7％) (P ＜ 0.05).The bone cement volumes in groups H and L were 4.94 ± 0.72 mL and 4.89 ±0.75 mL respectively,showing no statistically significant difference between the 2 groups (P ＞ 0.05).The leakage rate in group H was significantly lower than that in group L (13.33％ versus 35.48％) (P ＜ 0.05).All the patients were followed up for a mean time of 12 months (range,from 3 to 17 months).Cauda equina symptoms were observed in one patient and compression fracture of the adjacent vertebra happened in 2 patients,but no infection or pulmonary embolism occurred in any patient.Conclusions Both high viscosity cement PVP and low viscosity cement PVP can relieve back pain and improve quality of life in patients with severe OVCF,but the former may increase the efficacy and safety of PVP obviously in correction of cobb's angle,height restoration of the injured vertebra and reduction of cement leakage.
