Objective To analyze the influence of radial neck fracture on the upper limb function in older children,and to evaluate the curative effect of plate fixation in the treatment of Salter-Harris Ⅱ type of radial neck fracture.Methods The clinical data of 16 older children with radial neck fractures who treated by T plate internal fixation were retrospectively analyzed.16 cases were closed fractures,merging radial nerve injury in 1 case,3 cases of distal humerus fractures,1 case with rib fractures,fractures were Salter-Harris Ⅱ type,adopt steel plate internal fixa tion.Results 1 6 patients were followed up for 9-1 8 months.X-ray healing time was 6-9 weekson average 7.6 weeks.No malunion and no healing,no case of epiphyseal injuries.1 patient appeared steel block forearm supination.Postoperative patients with forearm pronation were greater than 90° supination were greater than 60 °.No radial nerve injury.Evaluation results were good.Conclusion Clinical treatment effect of open reduction and plate internal fixation in the treatment of older children with Salter-Harris Ⅱ type of radial neck fracture is satisfactory.Surgical treatment not only can enhance the fracture stability,but also can do the elbow joint function exercise to prevent dysfunction much earlier.

Objective To investigate a possible association of donor-recipient compatibility for ABO blood group alleles with acute rejection (AR) in renal transplantation. Methods A study comprising 87 pairs of donor and recipient was performed. The ABO genotype A1, A2, O1, O2, and B alleles of renal transplanted recipients and their respective donors were assessed by PCR amplification with sequence-specific primers (PCR-SSP). Accordingly, recipients were divided into donor-recipient ABO genotype matched and mismatched groups. Results The PCR-SSP based types of all cases showed total concordance with their serologically assigned ABO groups. Fifty pairs (57. 5%) were matched for ABO genotype among the 87 pairs of donor and recipient while 37 (42. 5%) were mismatched, including 1 allele mismatch in 31 pairs (83.8%), 2 alleles mismatches in 6 pairs (16. 2%).The incidence of AR was 12.0% (6 cases) and 29. 7% (11 cases) for ABO genotype matched and mismatched transplant patients, respectively ( P ＜ 0.05). After high dose methylprednisolone (MP)treatment, all cases exepienced reversion of AR except a A2O1 recipient receiving kidney from a A1O1enced 4 AR episodes within 3-10 months, and the period of AR was gradually shortened. After high dose MP was administered empirically, even though short-term improvement of renal function was observed, the serum creatinine continued to increase progressively with decreased efficacy of high dose MP. One year after operation the serum creatinine rose to 441 μmol/L. Conclusions Simultaneous definition of the ABO genotype and HLA is highly feasible. The A2 patient is suitable for receiving kidneys from blood group O donors. DNA mismatch for ABO genotype of renal transplant recipients and their respective donors is an independent risk factor for AR. Genotyping of ABO blood group is conducive to prevent AR.

Objective Through detecting the expression of erbB-2 and erbB-3 of epithelial growth factor receptor family in clinical specimens of salivary adenoid cystic carcinoma, to explore the role of erbB-2 and erbB-3 in the carcinogenesis and development of salivary adenoid cystic carcinoma. Methods Thirty-four specimens of adenoid cystic carcinoma were tested with immunohistochemical assay. Then the relationship between the expressions of erbB-2, erbB-3 and the gender, age of patients, TNM staging, tumor size and nerve invasion were analyzed.Results The positive expression ratios of erbB-2 and erbB-3 were 64. 7% and 32.4% respectively. And 29.4% of tumors were positively stained both by erbB-2 and erbB-3. The expression of erbB-3 was significantly correlated with TNM staging of tumors (P = 0. 026). The correlationship between the expressions of erbB-2 and erbB-3 was also found. Conclusions erbB-3 and erbB-2 may play important roles in the carcinogenesis and development of salivary adenoid cystic carcinoma. The positive expression of erbB-3 was associated with the biological behavior of tumors and prognosis of patients, and might become one of markers to evaluate the prognosis of patients.

Objective To compare the clinic effect of the locking compression plate (LCP) fixation and the anatomical plate in treatment of high-energy distal tibial fractures. Methods The study involved 42 patients with high-energy distal tibial fractures treated between May 2003 and May 2009. The anatomical plate group included 24 patients ( 16 males and 8 females, at average age of 39 years), of whom there were 13 patients with type A fractures, five with type B and six with type C according to the AO/ASIF classification. The LCP group included 18 patients ( 15 males and 3 females, at average age of 40 years), of whom there were 11 patients with type A fractures, three with type B and four with type C according to the AO/ASIF classification. All the patients were followed up for 8-17 months. Their functional and radiographic outcomes were collected. The operation time, intra-operative blood loss, X-ray exposure, bone healing time, post-operative complications and therapeutic effects were compared between both groups. Mazur's criteria was used to evaluate the function of the ankle. Results The LCP group was followed up for average 11.6 months and the anatomical plate group for average 14.2 months, which showed fracture healing in all the patients. The bone graft in the anatomical plate group was used more frequently than the LCP group, while the X-ray exposure in the LCP group was much more than that in the anatomical plate group. The operation time, incision size, blood loss, postoperative complications and radiographic bone healing time in the LCP group were significantly less than those in the anatomical plate group. Conclusions Both the LCP and anatomical plate are effective methods for the high energy distal tibial fractures. LCP has advantages of less trauma, quick fracture healing and less complications, is consistent with the biomechanics of internal fixation and hence is an ideal method for the treatment of the high-energy tibial fractures.

Objective To observe the clinical outcome of modified posterolateral approaches for the treatment of posterolateral tibial plateau fractures. Methods From January 2012 to January 2015,13 patients with posterolateral tibial plateau fractures were identified in the Second Hospital of Changzhou Affiliated to Nan?jing Medical University. All the posterolateral fractures were fixated with a plate. The knee function was evaluated at the last follow?up by the Hospital for Special Surgery( HSS) Score,and the occurrence of postoperative compli?cations were observed. Results Thirteen patients were followed up for an average of 14. 4 months,all patients obtained bony union. There were no significant differences regarding the mean HSS score among 3 months, 6 months and 1 year post?operation((71. 6±1. 5) points, (76. 4±1. 6) points, (83. 2±1. 1) points;P=0. 154) . There were no significant differences regarding the tibial plateau angle and posterior slope angle on radiograph?ies of inside and outsideamong immediate,6 and 12 months postoperation((83. 7±1. 7)°,(84. 3±1. 5)°,(85. 1 ±1. 4)°,(85. 4±1. 5)°;(7. 7±1. 5)°,(7. 7±1. 4)°,(7. 7±1. 3)°,(7. 6±1. 8)°;P=0. 223,0. 191). No com?plications associated with the approach were observed and there was no infection,no malunion or fixation failure either. Conclusion In the treatment of posterolateral tibial plateau fractures,the modified posterolateral approa?ches can result in excellent fracture reduction under direct visualization and allow for posterior buttress plating.

17 patients with maxillary antral pseudocyst underwent side wall fenestration with simultaneous implantation of 38 implants and the upper denture repair, follow-up observation was conducted after repair for 6 to 24 months (an average of 11. 4 months) .

Adiponectin, an adipocytokine secreted by adipocytes, has emerged as a potential treatment agent for type 2 diabetes. Adiponectin plays a variety of physiological roles in regulating glucolipid metabolism, oxidative stress, inflammatory responses and bone metabolism by binding to its receptors expressed on a variety of cells and tissues. Numerous studies have confirmed the strong association of adiponectin with type 2 diabetes-related periodontitis. Adiponectin can improve systemic insulin resistance by increasing insulin sensitivity and promoting insulin secretion. It improves the periodontal inflammatory response by inhibiting the expression of proinflammatory cytokines induced by Porphyromonas gingivalis lipopolysaccharide and promoting M2-type polarization of macrophages. In addition, adiponectin inhibits osteoclast differentiation and maturation through various pathways, such as Wnt/β-catenin and NF-κ, and promotes osteoblast differentiation to regulate bone metabolism, thus improving periodontal bone resorption and destruction. Therefore, adiponectin is expected to become a therapeutic target for type 2 diabetes-related periodontitis. Due to the physiological characteristics of adiponectin, its clinical application has been somewhat limited. This article reviews the latest research progress on adiponectin in type 2 diabetes-related periodontitis, aiming to elucidate the possible effects of adiponectin on type 2 diabetes-related periodontitis in terms of glycemic control, anti-inflammation and bone metabolism and to provide some opinions on the treatment of this disease and the development of relevant drugs.
