Objective To explore the risk factors of death in infant with muggy syndrome(IMS).Methods Sixty-three children with IMS were analyzed retrospectively, who admitted from Jan. 2002 to Feb. 2007,and these children were divided into groups according to the presence or absence of combined conditions including metabolic acidosis, hyperglycemia, hypocalcemia, ultrahyperpyrexia, pediatric critical illness score(PCIS) or number of the multiple organs failure. The ?2 test was used to examine the mortality between those groups.Results The total mortality of these children with IMS in-hospital was 22.1%. There were significant differences in mortality between combining metabolic acidosis and non-combining ones (RR=3.20,95%CI=1.0-10.24 ?2=4.76 P80 score (RR=12.73,95%CI=1.78-91.04,?2=13.24 P12 mmol/L and those

Objective To investigate Chlamydia trachomatis infection and gene variants in child- bearing women in Beijing. Methods Endocervical samples were collected from 177 patients in a family planning clinic and a gynecologic clinic. C.trachomatis infection was screened with a fast diagnostic kit .Major outer membrane protein(MOMP) gene was amplified by a nested PCR . A 1.1kb amplified product was obtained and studied by restriction fragment length polymorphism analysis(RFLP). Variant domains of MOMP gene VS1,VS2,VS3,VS4 were sequenced with 373A automated sequencing system. Results C. trachomatis was found in 9 of 177 samples. Four samples were identified as F genotype, 3 E genotype and 2 D genotype. Variant domains of MOMP gene, VS1, VS2, VS3, VS4 were sequenced and the results were consistent with those of RFLP, however, mutations were found in MOMP gene in 4 samples. Conclusion C.trachomatis urogenital infection has been identified in a portion of child- bearing women in Beijing. C.trachomatis can be well genotyped with RFLP or gene sequencing of MOMP gene.

Purpose To investigate the expression of tumor buds and its relationship with clinicopathological characteristics in endome-trial carcinoma. Methods 47 cases of endometrial carcinoma were observed and analyzed by means of clinicopathologic data and im-munohistochemical staining. The connections between tumor buds and clinicopathologic parameters were studied by statistics. Results Of the 47 endometrial carcinoma cases, tumor buds were seen in 18 cases. Tumor buds were correlated with histological grade, lymph node metastases, vascular invasion, Ki-67 index and survival. There were no associations between tumor buds with age, tumor size, pTNM stage or myometrial invasion depth. Immunohistochemistry demonstrated that the level of N-cadherin, vimentin in bud cells was higher than normal carcinoma cells while the level of CK(AE1/AE3),β-catenin and E-cadherin got the opposite results. Conclu-sion Tumor buds may play an important role in the progression of endometrial carcinoma. The immunohistochemical features of bud cells indicated that tumor buds may be a key step in epithelial-mesenchymal transition.

BACKGROUND:Macrophage migration inhibitory factor is involved in the process of a variety of diseases, and plays a very important role in the tumor, autoimmune diseases, inflammation, angiogenesis, fibrotic diseases and so on. These biological characteristics are similar to keloids. OBJECTIVE: To compare the distribution and number of macrophage migration inhibitory factor in normal skin, hypertrophic scar and keloid. METHODS: We colected 40 clinical pathological scar specimens after surgery, including 20 hypertrophic scars and 20 keloids. Another 10 samples of the normal skin were used as control group. Hematoxylin-eosin staining and immunohistochemistry staining were performed to test the expression of macrophage migration inhibitory factor in pathological scars and normal skin. RESULTS AND CONCLUSION:Macrophage migration inhibitory factor was positively expressed in the normal skin, hypertrophic scar and keloid, and the expression of macrophage migration inhibitory factor in keloid was significantly higher than that in hypertrophic scar and normal skin (P < 0.01). It means that the abnormal infiltration of macrophage migration inhibitory factor may be associated with the formation of keloid.

Objective To evaluate the clinical efficacy of a self-designed novel n-shaped aiming device in aiding the percutaneous cannulated screwing for treatment of odontoid fractures of Anderson-D' Alonzo type Ⅱ and shallow type Ⅲ.Methods A retrospective analysis was conducted of the 17 patients who had been treated at our department for odontoid fracture of Anderson-D' Alonzo type Ⅱ and shallow type Ⅲ between January 2009 and December 2013.They were 13 males and 4 females,with an average age of 37.5 years (from 16 to 61 years).All received surgical treatment after skull traction or jaw pillow traction preoperatively for reduction.Intraoperatively,percutaneous cannulated screwing via the anterior cervical approach was performed with the help of a self-designed novel n-shaped aiming device to fix the odontoid.Postoperatively,X-ray and CT scan were used to check the screw locations and evaluate the fracture healing.Results The 17 cases were followed up for 6 to 15 months (average,10.5 months).No intraoperative injury to the esophagus,artery,spinal cord or nerve root happened.The operating time ranged from 60 to 125 min.The bleeding was from 10 to 40 mL.Intraoperative observation revealed fine locations of the screws.Bony union was achieved in 16 cases 3 months postoperatively while separation and hardening of the fracture ends was found in one ease.Conclusion Our self-designed novel n-shaped aiming device can facilitate the percutaneous cannulated screwing for treatment of odontoid fractures of Anderson-D'Alonzo type Ⅱ and shallow type Ⅲ,given that it has advantages of simple manipulation,accurate insertion,minimal invasion,quick recovery and reliable efficacy.

Objeetive To assess the study outcomes in a consecutive series of patients with thoracic disc herniation (TDH) who undergone posterior spinal canal decompression and discectomy with segmental instrumentation and fusion.Methods Between January 2005 and June 2012,the data of 17 patients (11 males and 6 females) was retrospectively reviewed and analyzed.Disc herniation was classified as central in 10 cases and paracentral in 7 cases.The average canal encroachment was 71.7％±9.6％ (range,52％ to 90％).Their mean age at surgery was 55.7 years (range,21 to 81 years).All patients underwent a transfacet decompression and segmental instrumentation with interbody fusion.The data of patients included clinical presentation,blood loss,operative time,complications,visual analogue scale (VAS),Japanese Orthopaedic Association (JOA) score,and Frankel grading system.Results The average follow-up period was 37±12 months.The average surgical time was 120±63 min.The mean blood loss was 471±198 ml.Mean preoperative VAS score was 8.01±0.21,which improved to a mean of 1.12±0.07 at final follow-up.Average pre-and post-operative at 12 months JOA scores were 3.17±0.83 and 8.78±0.94 points,respectively.The average recovery rate was 65.1％±23.4％.Overall JOA scores showed a significant postoperative improvement.All patients reported 1 or 2 grade improvement in Frankel grading compared with preoperative status except for 1 patient whose grade had not changed.There were three complications,including one patient developing postoperative wound infection,one experiencing a cerebrospinal fluid leakage,one developing further neurological deterioration.Conclusion The results suggested that the posterior approach using special shaped osteotomy is feasible for central calcified TDH.No major complications occurred for achieving adequate decompression for central calcified TDH.
