Objective To discuss the expression of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) in adenomyosis and its clinical significance. Methods The expression of COX-2 and VEGF was examined by immunohistochemistry SP method, in ectopic endometrium and eutopic endometrium, compared with normal endometrium. Results (1) COX-2 expression in ectopic, eutopic endometrium with adenomyosis was significantly higher than that in control group (P<0.05). No statistically significant difference was found between ectopic endometrium and eutopic endometrium group with adenomyosis (P0.05).(2) VEGF expressions in ectopic, eutopic endometrium with adenomyosis were both significantly higher than that of control group (P<0.05); no statistically significant difference was found between ectopic endometrium and eutopic endometrium group (P0.05).(3) COX-2 and VEGF had the positive relativity in the ectopic endometriumal expression of adenomyosis patient (P<0.05). Conclusion COX-2 and VEGF may play a key role in adenomyosis. Both may have close relation in angiogenesis and may provide new targets for therapy of adenomyosis.

Objective:To study the morphological characteristics of temporo-mandibular joint with high angle vertical skeletal pattern in adult females with class II skeletal type.Methods:41 CBCT films of adult females (20 normal controls;21 skeletal class II high angle subjects)were collected.The position of and form of condyle,form of fossa and joint spaces were measured by Mimics 17.0 soft-ware.Results:Compared with the control group the condyles in high angle patients located more posterior.The joint fossae were lower. The angles of posterior joint node bevels were smaller.The condyles were shorter,thinner and tipped more anteriorly.The position of the conyles were more anteriorly.Conclusion:Class II skeletal type adult females with high vertical skeletal patterns have different forms of fossae,different positions and forms of condyle compared with the normal controls.

Objective To systematically evaluate the curative effect and safety of treating winter diseases in summer acupoint application therapy for asthma in children.Methods The domestic and international databases were retrieved till Feb 2017.The randomized controlled trials about treatment of treating winter diseases in summer acupoint application therapy for children with asthma were identified.The methodology quality of included trials was assessed.Results A total of 3 RCT involving 146 patients were included.The compositions of Chinese medicines and acupuncture points used were quite diverse,which inhibited us to conduct meta-analysis.The methodological quality of included RCT was generally lower.The results showed that treating winter diseases in summer acupoint application therapy might have advantage in reducing asthma acute attack times and improving clinical symptoms and respiratory function.Conclusion treating winter diseases in summer acupoint sticking therapy for asthma in children may have some advantages,however,due to the lack of a number of trials and poor methodology quality,the claimed benefits of treating winter diseases in summer acupoint sticking therapy for for children with asthma are inconclusive;more rigorous studies are warranted to support clinical practice.

Objective:To observe the histological character of distraction osteogenesis(DO) in the mandible of goat using an intraoral tooth-supported distraction device. Methods:8 goats (7-9 months of age) were divided into 4 groups with 2 goats per group. After a bilateral mandibular corticectomy between the second and third premolars, self-produced intraoral tooth-supported distraction devices were cemented. 5 days after operation,the distraction devices were begun to be activated 0.25 mm every 12 hours to advance the anterior segment 8 mm in 16 days. The animals of 32 days group were injected with tetracycline fluorescence labeing at 10 ml/kg once perweek from the beginning of DO.The animals were sacrificed on day 8,16,32 and 48 separately post activation, and tetracycline fluorescence labeling,HE staining and Mallory's 3-color staining were performed. Results:Tetracycline fluorescence labeling showed that there was green-yellow fluorescence labeling new bone within the distraction gap; HE and Mallory's trichrome staining showed that new bone gradually formed from bilateral sides, gradually blending and remodeling. The fiber bundles and newly formed trabeculas and various cells in early phrases showed to be orientation-directed along the axis of distraction force. Conclusion: New bone can be formed and regenerated along the axis of distraction force within the distraction gap.

Objective To report carpal tunnel release using Universal Subcutaneous Endoscope System from anatomical and clinical point of view for the purpose of avoiding operative complication and improving clinical efficacy. Methods Operation approach and adjacent structures were observed and measured on 18 fresh upper limb specimens and 26 formaldehyde solution fixed upper limb specimens. Nineteen patients with 21 carpal tunnel syndrome (CTS) were treated with this method under local anaesthesia without tourniquet. The incision is made in the wrist just 2-3 cm superior to palmar crease of the wrist at the medial border of the palmaris longus. The operation plane is just under the deeper layer of deep fascia. The instrument points to the third web. The median nerve and its branches, flexor retinaculum and superficial palmar arch were carefully observed. Results The results were satisfactory in all patients. Conclusion Single wrist portal arthroscopic procedure is a safe, simple and efficient approach if the anatomic structures of the wrist are perfectly clear to the opeator.

Objective To investigate and analyze the postoperative progression of ossification of the patients with ossification of the posterior longitudinal ligament (OPLL) on cervical spine. Methods From Jaunary 2001 to December 2007, 95 postoperative patients with cervical OPLL were followed and analyzed retrospectively. There are 72 males, 23 females, with the average age of 56.3 years (range, 40-73years). The follow-up time was from 1 to 6 years, average 3.1 years. Among them 36 patients were performed with anterior cervical corpectomy, fusion with titanium mesh and fixed with cervical plates, others treated with posterior cervical laminectomy and fixation. 2 of the 95 cases were performed anterior and posterior combined operation. Clinical data, X-rays, CT and MR images and progression of ossification, were measured and analyzed in details .The relationships between the progression of ossification and relative factors, as gender, age, C3 ossified involved, T-OPLL, OPLL-type, time of follow-up, surgical approach, Japanese Orthopaedic Association (JOA) scores and improvement rate of JOA scores, were analyzed. Results Progression of ossification in 39 cases among the 95 followed postoperative OPLL patients, 28 men and 11 women, average age 55.9 years, range 41-71 years. The age of progressed patients included 12 cases of ≤49 years, 12of 50-59 years, 12 of 60-69 years and 3 of ≥70 years. 35 patients were operated by posterior approach and only 4 treated with anterior operation. According to the standard of the progression of ossification that 2 mm in the length or/and thickness, there are 4 cases progressed only in length, 2 only in thickness, other 33 patients both the length and thickness. Progression of length is from 2mm to 20mm (average 7.74±4.71). But thickness is progressed from 2 mm to 6 mm (average 2.67±1.51). From 1 to 3 years follow-up time it appeard as a downtrend about the progression of ossification. But it may appear an uptrend from the 4th year. JOA score and improvement rate of the JOA score were almost improved to the high-point in three years. And according to the statistic data there are obvious relationship between progression of ossification with age, surgical approach and C3 ossified involved. Conclusion There is a high rate of postoperative ossification progression in cervical OPLL patients. Cervical OPLL patients with C3 ossification involved, performed with posterior laminectomy and those young at surgery may have higher rate of progression of the ossification. The JOA score and improvement rate of the JOA score were little influenced by the progression of the OPLL during the short and intermediate-term follow-up.
