Objective To observe the anatomy of the inferior right hepatic veins (IRHV).Methods The IRHVs were divided into 3 groups according to the location where they entered into the retrohepatic inferior vena cava at: the upper 1/3, middle or lower 1/3. The incidence, number, caliber, extrahepatic length and the relationship between the major hepatic veins (the right, middle and the left hepatic veins) and the IRHV were observed and measured in 60 adult cadavers. Results The incidence of IRHV was 83.33% with an average diameter of 2.62-18.46(14.32±1.21)mm. Its extrahepatic length was 3.26-47.65 (10.78±7.81)mm. There was a marked negative correlation between the diameter of the IRHV and its number, a marked negative correlation between the diameter of the IRHV and the diameter of the right hepatic vein and a marked positive correlation between the number of the IRHV and the diameter of the right hepatic vein. Conclusions There were high variations in the incidence and anatomy of the IRHV which were related to the diameter of the right hepatic vein. The IRHV was not to be torn during liver resection and should be reconstructed in right liver grafts.

Conclusion PSP can increase the activity of DNA endonuclease and DNA ligase in dose-de- pendrntly.

Objective To evaluate the clinical effect ofXugu-Huoxue decoction combined with anatomical reduction and internal fixation with cannulated screws in patients with femoral neck fractures. Methods A total of 89 patients with femoral neck fractures were randomly divided into a control group and a Xugu-Huoxuegroup according to the random number table, with 46 in the control group and 45 in the Xugu-Huoxuegroup. The control group was treated with anatomical reduction and internal fixation with cannulated screws, while theXugu-Huoxuedecoction group was treated withXugu-Huoxuedecoction on the basis of the control group. The hemodynamics of the femoral vein was evaluated with color Doppler sonography. Hip function was rated with Harris hip score.ResultsAfter 12 months of treatment, the minimum diastolic velocity (12.0 ± 2.2 cm/svs.9.3 ± 2.0 cm/s;t=3.675,P<0.01), diameter (0.8 ± 0.3 cm vs. 0.6 ± 0.1 cm;t=3.675, P<0.01) and blood flow (1 123.4 ± 271.1 ml/minvs.901.2 ±121.1 ml/min;t=5.067,P<0.01) of the femoral vein in theXugu-Huoxuedecoction group were significantly increased than those in the control group. The rates of excellent or good in theXugu-Huoxuedecoction group and the control group was 86.7% (39/45) and 63.0% (29/46), respectively, with statistically significant difference (χ2=5.529,P=0.019). There were 2 patients (4.4%) with delayed fracture healing and 2 patients (4.4%) with femoral head necrosis in theXugu-Huoxuedecoction group, while 3 patients (6.5%) with delayed fracture healing, 5 patients (10.9%) with femoral head necrosis inthe control group, without statically significant difference (χ2value were 0.000, 0.572,P value were 1.000, 0.449, respectively).ConclusionXugu-Huoxue decoction combined with anatomical reduction and internal fixation with cannulated screwscan improve the fracture prognosis and the joint function in patients with femoral neck fractures.

Objective We tried to investigate the current status of pediatric nursing post setting and analyze the practical application effect in the clinical working practice for the foundation of readjusting and setting up the pediatric nursing positions.Methods By convenient sampling method,the general condition and current post setting situation in the pediatric wards of 7 hospitals with self-designed questionnaires were investigated.The results underwent analysis Results The nursing post setting in pediatric wards of 7 hospitals were not all the same,nursing posts in the pediatric ward included three categories:management positions,teaching positions and clinical positions.Management positions included the head nurse,deputy head nurse and head nurse assistant; teaching positions included the teaching secretary and clinical total teaching nurse; the seven kinds of clinical nursing positions were office job,day shift,night shift,evening shift,midnight shift,late-morning shift,auxiliary job.Though some nursing jobs differed in the position names and working hours,their job contents were nearly identical.Conclusions Pediatric nursing post setting management in our country is still in the exploratory stage at present,it has not form a unified perfect job management system.Pediatric nursing positions should be set from the perspective of evidencebased theory,satisfying the demands of patients as the guidance,coming from clinical needs as the first principle,in the full implementation of the accountability for nursing and based on comprehensive consideration of various factors,so that the post setting can be scientific and reasonable.

Objective To analyze the features of normal high-frequency ultrasonography of tarsal tunnel. Methods Forty volunteers (20 males and 20 females) were examined with high-frequency ultrasound (12 MHz). The tendons,nerve and blood vessels in tarsal tunnel were observed from short-axis and long-axis views dynamically. The areas of tarsal tunnel and posterior tibial nerve were measured and com-pared between the males and females. Results High-frequency ultrasonography depicted the anatomical structure of tarsal tunnel,and the tendons,nerve and blood vessels presented different sonographic features that were easy to differentiate. The area of tarsal tunnel: male (7.61 ±1.00) cm2,female (6. 61 ± 1. 07) cm2 (P <0. 01). The area of posterior tibial nerve: male (9. 59 ± 0. 75) mm2,female (8.91 ±0.74) mm2(P<0.01). Conclusion High-frequency ultrasonography can clearly show and accurately measure the tarsal tunnel structure. To be familiar with the normal ultrasonographic anatomy of tarsal tunnel will help to improve the efficacy of ultrasound diagnosis of tarsal tunnel abnormalities.

Objective To investigate the correlation between serum osteocalcin and type 2 diabetes mellitus (T2DM) in elderly patients.Methods A total of 55 T2DM patients (diabetic group) and 50 non-diabetic subjects (control group) aged ≥60 years were enrolled in this study.The levels of fasting blood glucose (FBG),glycated hemoglobin (HbAlc),insulin resistance index (HOMA IR),osteocalcin (OC),body mass index (BMI) and bone mineral density (BMD) in groups were compared.The correlations between serum osteocalcin and the above indicators were analyzed.Results The levels of OC and BMD were higher in control group than in diabetic group [(11.2±3.2)μg/Lvs.(4.1±3.0)μg/L,(-1.3±0.3) vs.(-2.6±0.5),respectively,both P＜0.05].The levels of FBG,HbAlc,FINS,HOMA-IR were lower in control group than in diabetic group [(4.7±2.0) mmol/L vs.(9.4±2.1) mmol/L],[(4.8±1.5) ％ vs.(7.6±1.6)％,(7.4±3.2) U/L vs.(23.7±3.0) U/L,(1.5±0.7) vs.(9.9±1.2),respectively,all P＜0.05].Serum osteocalcin concentration was negatively correlated with the levels of FBG,HbAlc,FINS and HOMA-IR in elderly patients with T2DM (r=-0.739,-0.713,-0.613,-0.092,all P＜0.01).Conclusions Serum osteocalcin concentration is correlated with the levels of blood sugar and insulin resistance index in elderly patients with T2DM.A further study on the correlation between osteocalcin and T2DM may provide a new target for the treatment of type 2 diabetes mellitus.
