OBJECTIVETo investigate the clinical outcomes of cannulated screw combined with buttress plate in treating transarticular shear fractures of the distal humerus.

METHODSFrom July 2008 to December 2011, 17 patients with shear fractures of the distal humerus were treated with cannulated screw combined with buttress plate. Among them, included 10 males and 7 females aged from 20 to 59 years old (mean 36.5). All the fractures were classified into type I (8 cases), type II (1 case), type III (3 cases) and type IV (5 cases) according to Bryan-Morrey and McKee classification. According to AO/ASIF classification, 10 cases were type 13B3.1, 7 cases were type 13B3.3; according to Dubberley classification, 5 cases with type 1A, 2 cases with type 1B, 2 cases with type 2A, 2 cases with type 2B, 4 cases with type 3A, 2 cases with type 3B. There were 12 cases with fresh injuries, 4 cases with old injuries. All fractures were closed injuries. Complications and range of motion of elbow were observed, and clinical efficacy were evaluated by Broberg-Morrey standard.

RESULTSAll patients were followed up with a mean time of 21.3 months (ranged, 18 to 24). All fractures obtained bone healing from 10 to 15 weeks with a mean of 12.5 weeks. No malunion or delayed healing occurred. Two cases occurred ossification in lateral collateral ligament attachment. 2 cases occurred heterotopic ossification in the capitellum in front of capsule joint. The range of elbow extension was (16 +/- 7) degrees, flexion was (115 +/- 9) degrees, the average are of pronation and supination was (65 +/- 5) degrees and (60 +/- 5) degrees respectively. According to Broberg-Morrey standard, there were excellent in 7 cases, good in 8 cases, fair in 2 cases, and average score was 92.44 +/- 4.64.

CONCLUSIONFor transarticular shear fractures of the distal humerus, classification should be performed according to preoperative X-ray and CT, cannulated screw and buttress plate combined and early function rehabilitation could recover elbow function.

Objective To explore the clinical characteristics of neonatal dengue fever. Methods The clinical data from 4 neonates with dengue fever who were admitted and treated in 2014 were retrospectively analyzed and the related literatures had been reviewed. Results Four cases of neonatal dengue fever were all males. Three cases were mother to child transmission, the age at onset was 1 to 7 days after birth, and their mothers suffered with prenatal fever and were diagnozed of dengue fever during perinatal period. One case was community acquired, the age at onset was day 21 after birth and the neonate was bit by mosquito the day before. All four neonates had fever, two cases had rash, and one case had hemorrhagic spot. None of them had jaundice or cough. All of them had thrombocytopenia ( 30-125 )× 109/L, prolonged activated partial thromboplastin time ( 44 . 0-89 . 8 s), and increased aspartate aminotransferase (AST) ( 46-71 U/L). Three cases had declined ifbrinogen ( 1 . 36-2 . 53 g/L). Two cases had increased CK-MB ( 29-86 U/L). Two cases had increased CRP ( 3 . 00-46 . 05 mg/L). After the treatment of anti-infection and intravenous immunoglobulin, all of them were cured and discharged. The duration of hospital stay was 4-17 days. Conclusion The clinical manifestations of neonatal dengue fever were mainly fever and blood coagulation dysfunction, clinical symptoms are mild and lack of speciifcity, and prognosis are good. Mother to child transmission is one of the ways of dengue virus infection.

Objective To determine the risk factors for imipenem-resistant Pseudomonas aeruginosa (IRPA) infections in neonatal intensive care unit (NICU).Methods One hundred and eighty-eight Pseudomonas aeruginosa infected children (confirmed by pathogenic examination) in the NICU of Maternal and Child Health Hospital of Guangdong from January 1,2008 to December 31,2011,were chosen as the objects of study,and were divided into two groups.The first group included 73 children that had been isolated with IRPA strains(IRPA group),and the second group included 115 children that only had imipenem-sensitive Pseudo monas aeruginosa (ISPA) strains (ISPA group).Chi-square test or t-test was applied.The risk factors were investigated by univariate or multivariate Logistic regression analysis.Results Data from univariate analysis showed that the gestational age and birth weight of neonates were lower than those in ISPA group [(34.0±3.5) weeks vs (35.6±2.8)weeks,t=3.413,P＜0.01; (1848.1±276.4) g vs (2110.7±345.6) g,t=5.472,P＜0.01].There were more neonates with gestational age ≤ 32 weeks [67.1％ (49/73) vs 45.2 ％ (52/115)],birth weight ＜1500 g [73.9％ (54/73) vs 33.0％(38/115)],small for gestational age [68.5％ (50/73) vs 29.6％ (34/115)],receiving imipenem [72.6％ (53/73) vs 27.0％ (31/115)] or the third generation cephalosporins [65.8％ (48/73) vs 33.0％ (38/115)] two weeks before the isolation of Pseudomonas aeruginosa,and mechanical ventilation [78.1％ (57/73) vs 61.7 ％ (71/115)],deep vein catheterization [83.6％(61/73) vs 65.2％(75/115)] in the IRPA group than in the ISPA group (all P＜0.05 or 0.01).The multivariate Logistic regression analysis revealed that imipenem treatment within two weeks before the isolation of Pseudomonas aeruginosa (OR=6.409; 95％ CI:1.926-21.333,P =0.002) was an independent risk factor.Conclusions IRPA infection in NICU hospitalized infants is strongly related to their gestational age and birth weight.History of imipenem administration could be an independent risk factor.

OBJECTIVETo investigate the therapeutic efficacy of bone-setting manipulative reduction and small splint fixation combined with micro-movement theory exercise for treatment of humeral shaft fractures.

METHODSFrom March 2011 to February 2014, 64 cases of humeral shaft fractures were treated by bone-setting manipulative reduction and small splint fixation including 28 males and 36 females with an average age of 38.1 years old ranging from 22 to 67 years old. According to the classification of AO/OTA, there were 10 cases of type A1, 12 cases of type A2,11 cases of type A3,10 cases of type B1,12 cases of type B2, 7 cases of type B3, 2 cases of type C1, 1 case of type C2, 1 case of type C3. After close reduction early functional exercise performed according to micro-movement theory. All patients had no other parts of the fractures, neurovascular injury, and serious medical problems. Patients were followed up for fracture healing, shoulder and elbow joint function recovery, and curative effect.

OBJECTIVETo determine the expression of Skp2 in different prostate cancer (PCa) cell lines and tissues, and explore its influence on the androgen receptor (AR) signaling pathway and development of castration-resistant prostate cancer (CRPC).

METHODSThe expression levels of Skp2 and AR in different PCa cell lines were detected by Western blot. After knockdown of Skp2 in the C4-2 and 22RV1 cells transfected with shRNA, the expressions of AR and P27 were determined and the activity of ARR3-Luc measured by dual-luciferase reporter gene assay following treatment with dihydrotestosterone (DHT). The expressions of AR and Skp2 in human naïve PCa or CRPC specimens were detected by immunohistochemical staining followed by analysis of their differences and correlation.

RESULTSThe Skp2 protein expression level was significantly higher in the C4-2 or 22RV1 cells than in the LNCaP cells. DHT treatment increased the expression of Skp2 in the C4-2 cells, but knock-down of Skp2 significantly up-regulated the expression of the well-known downstream protein P27 and down-regulated that of AR. Consistently, DHT treatment increased the activity of ARR3-Luc, while knockdown of Skp2 remarkably decreased it in the C4-2 and 22RV1 cells (P < 0.05). In addition, significantly higher expressions of Skp2 and AR were observed in the CRPC than in the naïve specimens (P < 0.05), with a positive correlation between the two proteins (r = 0.658 1, P < 0.05).

CONCLUSIONSkp2 can enhance the expression and transcription activity of the AR protein in CRPC cells or tissues and is promising to be a critical molecular therapeutic target.
