Objective To treat femur fracture in neonates using a new homemade harness designed and observe the effec of this harness. Methods Designed a new harness used in femur fracture in neonates,and used this harness in 7(8 femur fracture)csses,including 6 boys(7 femur fracture)and 1 girl,the age from 1 day to 12 days(average 4.7 days).Those cases included proximal thirds(2 cases)and middle thirds(6 cases)of femur fracture.The angle of fracture was from 44°to 83°(average 62.4°)before treatment. Results The angle of fracture was from 0°to 22°(average 14.0°)after treatment using the harness.Hespitalization was from 2 to 3 days.There were no skin sloughing or harness breaking off.All cases were followed up 6 to 36 months(average 21.3 months).All femur fracture healed in good alignment with leg-length discrepancy＜1 cm.Movement of hip and knee was normal. Conclusions The harness is a better method to treat femur fracture of the proximal and middle thirds in neonates.Advantages of it include simply operation,minimal hospitalization,minimal cost,and easy nursing.

To explore the effects of tetramethylpyrazine (TMP) on fibrosis of atrial tissue and atrial fibrillation in a canine model of congestive heart failure (CHF) induced by ventricular tachypacing.

Objective:To investigate the expressions of leptin receptor (OBR) and phosphorylated protein kinase B (p-AKT) in patients with diffuse large B-cell lymphoma (DLBCL) and its significance.Methods:Immunohistochemistry was applied to detect the expressions of OBR and p-AKT in tissues from 90 patients with DLBCL and 20 patients with reactive lymphoid hyperplasia (RLH) between 2010 and 2015 in Shandong Provincial Hospital Affiliated to Shandong First Medical University. Cell proliferation assay was used to detect the effect of leptin on the proliferation of SUDHL4 and SUDHL5 in DLBCL cell lines, and the expression of p-AKT in SUDHL4 and SUDHL5 after the cultured leptin was detected by using Western blot.Results:The high expression rate of OBR and p-AKT of DLBCL was 47.7% (43/90) and 27.7% (25/90), respectively, and low expression was found in 20 cases of RLH. There were statistically differences in the expressions of OBR and p-AKT in DLBCL and RLH ( P < 0.01, P = 0.027). The expressions of OBR and p-AKT were not correlated with age, gender, extranodal infiltrations, clinical staging, lactic dehydrogenase (LDH) level, B-symptom and international prognostic index (IPI) score (all P > 0.05). The expression of OBR was positively related with that of p-AKT in DLBCL patients ( r = 0.532, P < 0.05). Leptin could increase the proliferation of SUDHL4 and SUDHL5 cells and promote the expression of p-AKT. Conclusion:Leptin and OBR can promote the proliferation of DLBCL cells and may be involved in the occurrence and development of DLBCL by activating PI3K-AKT pathway.

The article analyzes chief physician SUN Wuquan's empirical characteristics in treating neck-type cervical spondylosis:disease differentiation combined with pattern differentiation,emphasizing the assessment of tendons and bones,with DING's Tuina(Chinese therapeutic massage)manipulations and static Gongfa(Qigong exercise)as the predominant treatment,inherits the academic features of DING's Tuina school,"paying equal attention to tendons and bones,putting function first";thus provides a reference for treating neck-type cervical spondylosis with Tuina therapy.

OBJECTIVE: To explore the application of the autoregressive integrated moving average model( ARIMA model)in predicting incidence of occupational noise-induced deafness( ONID). METHODS: The ARIMA model was established and validated based on the number of new onset ONID cases in Guangdong Province from 2006 to 2015. Then the ARIMA model was used to predict the trend of new onset ONID cases from 2016 to 2020. RESULTS: The number of new ONID cases in Guangdong Province from 2006 to 2015 showed an exponential growth trend. The optimal model fitted with the number of new onset ONID cases from 2006 to 2015 was the ARIMA( 2,2,2) model,which better match the number of new onset ONID cases from 2008 to 2015. According to the ARIMA( 2,2,2) model,the number of new onset ONID cases in Guangdong Province will continue to have a rapidly increasing trend from 2016 to 2020. CONCLUSION: The ARIMA model based on time series matches the time trend of ONID onset,and it can be used for the prediction of ONID incidence trend.
