OBJECTIVETo observe the clinical efficacy about manipulative reduction of the radialis and ulnar fractures.

METHODSFrom June 2005 to June 2009, 85 patients with radialis and ulnar fractures, 50 males and 35 females, ranging in age from 1 to 20 years with an average of 10.8 years, were treated with manipulative reduction and external fixation by small splint. There were 53 cases of direct violence, 30 cases of transmission violence, 2 cases of reversing violence; and there were 6 cases of comminuted fracture, 8 cases of spiral fracture, 21 cases of oblique fracture, 50 cases of serrated or transverse fracture. The clinical effects were analyzed according to Anderson criterion.

RESULTSForty-two cases obtained anatomical reduction and 35 cases obtained nearly anatomical reduction and 8 cases occurred re-displacement. Eight cases of re-displacement were re-fixed after manipulative reduction, 2 cases obtained anatomical reduction and 4 cases obtained nearly anatomical reduction; 2 cases unsuccessfully were diverted to open reduction and internal fixation. All the fractures obtained clinically healing with average of 42 days (ranged from 28 to 80 days). All patients were followed up from 3 to 10 months with an average of 7.5 months. According to Anderson criterion, 77 case got excellent result, 5 good, 3 fair.

CONCLUSIONManipulation and external fixation by small splint for the treatment of radialis and ulnar fractures, have advantage of less trauma, forceful fixation, quick healing, cheap cost, which can obtain satisfactorily clinical effects.

Blood C-peptide,first-void fasting urinary C-peptide/creatinine ratio ( UCPCR ),second-void fasting UCPCR,and 24 h urinary C-peptide (UCP) were determined in 90 type 2 diabetics and 30 health volunteers.The results showed that first-void fasting UCPCR and second-void fasting UCPCR were positively related to 24 h UCP and the index of islet β-cell function( all P＜0.01 ).

Preparation of maternal strain A/PR/8/34 HA antiserum for influenza virus classical reassortment. A/PR/8/34 virus was digested by bromelain after inactivation and purification. 5%-20% sucrose continuous density gradient centrifugation method was used to purify HA protein. SIRD method was used to select the target protein. SDS-PAGE method was used to identified HA protein. High Immunogenic A/PR/8/34 HA protein was successfully prepared and HI titer reached 10240. High purity HA antiserum was identified by SIRD method. The key reagent in the classical reassortment of influenza virus was prepared, and the complete set of technical methods were explored, which laid the foundation for the independent research and development of seasonal influenza vaccine strains of China.

There is a high risk of postoperative complication of ulcer perforation in senile patients, and there is no effective predictive method previously. Nutritional risk assessment improves clinical outcome and reduces the incidence of complication by receiving nutritional support treatment for patients at risk of nutrition. Aims: To investigate the predictive value of nutritional risk assessment for postoperative complication in elderly patients with gastroduodenal ulcer perforation. Methods: A total of 100 patients with perforation of gastroduodenal ulcer from January 2015 to December 2017 at Heyuan People's Hospital Affiliated to Jinan University were enrolled. NRS-2002 score and SGA score were used for nutritional risk assessment. The occurrence of postoperative complication was recorded, and risk factors of postoperative complication were analyzed by multivariate Logistic regression analysis. Results: NRS-2002 score showed that no nutritional risk in 37 patients, 63 patients with nutritional risk. SGA score showed that no malnutrition was found in 41 patients, moderate malnutrition in 32 patients, and severe malnutrition in 27 patients. There was no significant difference in the proportion of no malnutrition/nutritional risk between the two groups (P>0.05). Different degrees of complication occurred in 21 patients. NRS-2002 score and SGA score were correlated with the incidence of serious complication and infectious complication (P<0.05). Multivariate Logistic regression analysis showed that NRS-2002 score and SGA score were independent risk factors for postoperative complication of gastroduodenal ulcer perforation (P<0.05). Conclusions: NRS-2002 score and SGA score can be used to assess malnutrition in elderly patients with perforation of gastroduodenal ulcer. NRS-2002 score, SGA score are closely related to postoperative complication, and can be used to predict the risk of postoperative complication.

BACKGROUND:Osteopontin mRNA and protein expressions are highly correlated with the severity of osteoarthritis. OBJECTIVE:To investigate the effect of osteopontin on the gene expression of aggrecan and type II colagen in the human knee osteoarthritic chondrocytes in vitro. METHODS: Chondrocytes were harvested from human osteoarthritic knees and culturedin vitro. The chondrocytes were cultured with 0 (blank control group), 0.1, 1 mg/L osteopontin, respectively, for 48 hours. Real-time PCR was employed to detect the mRNA expression of aggrecan and type II colagen. RESULTS AND CONCLUSION:After 0.1 and 1 mg/L osteopontin intervention, the mRNA expression of aggrecan and type II colagen in osteoarthritic chondrocytes was increased significantly (P< 0.05), and the mRNA expression of aggrecan and type II colagen was higher in the 1 mg/L osteopontin group than the 0.1 mg/L osteopontin group (P< 0.05). In addition, the mRNA expression of aggrecan and type II colagen was positively correlated with the concentration of osteopontin (r=0.751,P < 0.01;r=0.676,P < 0.01). These findings indicate that osteopontin up-regulates the mRNA expression of aggrecan and type II colagen in osteoarthritic chondrocytes of human kneein vitro in a dose-dependent manner.
