BACKGROUND:Anti-rotation intramedulary nail fixation for proximal femoral fractures replaces the femoral bearing axis, moves towards body axis relative to hip screw and dynamic ankle screw, enhances the anti-fatigue strength at the fracture site, supports the anti-varus and prevents the rotation of the proximal fracture site, and is suitable for the treatment of unstable fracture. OBJECTIVE:To comparatively observe the effects of dynamic hip screw knife system and minimaly invasive spiral blade anti-rotation intramedulary nail in the repair of unstable intertrochanteric fractures. METHODS: A total of 82 cases of unstable intertrochanteric fractures, who were treated in the Department of Orthopedics, First People’s Hospital of Shunde from January 2012 to January 2014, were selected in this study. The patients were equaly and randomly divided into two groups: dynamic hip screw knife system group and minimaly invasive spiral blade anti-rotation intramedulary nail group. Repair index, fracture healing time and the incidence of complications were compared between the two groups. RESULTS AND CONCLUSION:Healing time and repair index were significantly better in the minimaly invasive spiral blade anti-rotation intramedulary nail group than in the dynamic hip screw knife system group (P < 0.05). Complications appeared in five patients from the minimaly invasive spiral blade anti-rotation intramedulary nail group, with the incidence rate of 12%, and in ten patients from the dynamic hip screw knife system group, with the incidence rate of 24%. The incidence of complications was significantly lower in the minimaly invasive spiral blade anti-rotation intramedulary nail group than in the dynamic hip screw knife system group (P < 0.05). These data suggest that for patients with unstable intertrochanteric fracture, minimaly invasive spiral blade anti-rotation intramedulary nail can decrease the incidence of complications, elevate the safety of the repair method, and promote the functional recovery.

Objective To explore the effect of situational health education on self-efficacy of primipara in breast-feeding and child rearing. Methods One hundred and eighty-five pregnant women taking prenatal examinations in our hospital from September 2012 to August 2013 were selected into control group and they received traditional education. Another one hundred and ninety-two pregnant women taking the same prenatal examinations in our hospital from Sep 2013 to Aug 2014 were selected into experiment group and the antenatal situational health education was applied . The self-efficacy in breast-feeding and child rearing of the two groups before and after discharged from hospital (6 weeks after delivery) were compared. Result The self-efficacy in breast-feeding and child rearing of the experiment group were significantly better than those of the control group and before discharged from hospital (P<0.05). Conclusion The situational health education is important for increasing self-efficacy in breast-feeding and child rearing and is beneficial for the growth and development of the neonates.

ObjectiveTo disuss the relationship of clinical symptoms of cerebral palsy and the morphologie changes of head CT. MethodsHead CT photos of 86 cases of cerebral palsy infants were inspected and analyzed.ResultsAmong 86 cases of cerebral palsy infants 66 cases were abnormal in CT scan, the abnormal rate was 76.7%, in which cerebral atrophy constituted the most part (59.1%) of abnormity. The younger the sufferers were, the higher the abnormal rate reached. Sufferers with suffocation in disease history had the highest CT abnormity rate. In clinical types, sufferers of spasticity had the highest CT abnormity rate. Conclusion Morphologic examination of head CT is vital to diagnose the cause of cerebral palsy, and helps to find pathologic changes early.

Objective To analyze the reasons of hypoglycemia in patients with diabetic ophthialmopathy,and summarize the corresponding nursing measures in order to reduce the incidence of hypoglycemia in patients with diabetic ophthialmopathy. Methods The reasons for hypoglycemia were analyzed for 43 patients with diabetic ophthalmopathiy in our hospital from January 2009 to November 2011. Results Taking the hunger-cure arbitrarily,no regular diet,no corresponding adjustment for the insulin quantity after stopping taking hormone medicine,and also after the diabetic symptoms relieved,besides,less food-intake caused by high pressure of eyes,vomiting and appetite decreasing after the vitreous body dissection,and the paramedic had no enough cognition for the harm caused by hypoglycemia,combination medication with cardiovascular medicine were the primary reasons for the occurence of hypoglycemia in patients with diabetic ophthalmopathy. Conclusions Many reasons can cause hypoglycemia in patients with diabetic ophthalmopathy,We should strengthen management,propaganda and education,observation of medication and disease condition as well as improve the attention of eye health care workers for hypoglycemia in order to reduce the incidence of hypoglycemia.

Intrahepatic cholangiocarcinoma is the second most common intrahepatic primary liver tumor after hepatocellular carcinoma (HCC).Epidemiological study suggests a strong correlation between HBV infection and ICC development.This review focused on the potential mechanisms of HBV-induced ICC and gives a primary summary of suggested hypothesis,which included:(1) HBV infection of liver stem/progenitor cells will indirectly lead to HBV infection of intrahepatic biliary epithelial cells and lead to the development of ICC; (2) the changed microenvironment of intrahepatic biliary epithelial cells by HBV infection eventually results in carcinogenesis ; (3) the HBV infection of hepatic sten/progenitor cell can transform into tumor-like stem cells and ultimately differentiate into ICC-like tumor cells.

Objective To investigate the effects of sevoflurane anesthesia on learning and memory functions and S100β protein in anaplasis in the 7-day-old rat.Methods 48 SD rats of both sexes aged 7-day-old weighing 1 2-1 6 g were randomly divided into 3 groups (1 6 rats in each group):group A and group B inhaled 3 ％ sevoflurane in oxygen(1L/min) for 6h and 2h respectively; group C inhaled oxygen(1L/min) only.After inhalation,the effects of sevoflurane anesthesia on learning and memory function were assessed by Morris water-maze test and Y-maze test from 16d to 24d.The rats were killed in the day of 8d and 25d respectively,and the blood were collected for the expression of serum concentration S100β protein by enzyme-linked immunosorbent assay.Results (1) Results of Morris water-maze test:Compared with group C,escape latency prolonged in group A and group B in 17-20d(P ＜ 0.05 or 0.01) ;escape latency prolonged in group A compared with group B in 19-20d(P ＜ 0.01) ;but there were no significant differences in the probe time in original platform quadrant and the frequency of crossing original platform among three groups(P ＞0.05).(2) Result of Y-maze test:In 22d,the total reaction time of group A and B were longer than group C (P ＜0.05 or 0.01),and the error number was increased in group A and B compared with group C(P ＜ 0.01) ; while in 23-24d,there were no significant differences between every index of each groups (P ＞ 0.05).(3) Results of the blood serum index:In 8d,serum concentration of S100β protein was significantly increased in group A and B compared with group C (P ＜0.01),and serum concentration of S100β protein was significantly increased in group A compared with group B (P ＜ 0.05) ; But there were no significant differences in serum concentration of S100β protein of each groups in 25d(P ＞ 0.05).Conclusion Sevoflurane anesthesia in the 7-day-old rat can temporarily decrease the ability of learning and memory functions in the length of inhalation time dependent manner,and the mechanism may be related to the increased expression of serum concentration of S100β protein transiently.

Objective To detect the changes in vertebral marrow fat fraction (MFF) using T2 *-corrected water-fat MRI and to analyze the relationships between MFF with bone biomarkers of non-dialysis chronic kidney disease (CKD).Methods 78 CKD patients were divided into five groups according to the eGFR and underwent water/fat MRI to obtain MFF.The reliability of MFF measurements by two radiologists was assessed with intra-class correlation coefficient (ICC).Serum calcium,phosphorus,alkaline phosphatase,osteocalcin,intact parathyroid hormone and 25(OH)D3 were determined.Results Mean CV for MFF measurements reproducibility was 2.37％.The inter-observer agreement for MFF was excellent (ICC=0.901).The ICC for each intra-observer agreement was excellent (ICC=0.959 and 0.948,respectively).There were statistical differences in MFF among five groups of CKD.Changes of MFF were earlier than those of serum calcium,phosphorus,parathyroid hormone,alkaline phosphatase and osteocalcin.MFF was positively correlated with serum phosphorus (r =3.011,P =0.003),parathyroid hormone (r=3.852,P＜0.001),and negatively associated with calcium (r=-2.767,P=0.017),25(OH)D3 (r=6.032,P＜0.001),eGFR (r=-5.104,P＜0.001),respectively.Multivariable regression analysis showed MFF was negatively correlated with 25(OH)D3(Sβ=-0.343)and eGFR(S(S=-0.284,P＜0.001).Conclusion CKD patients had higher marrow fat.T2 *-corrected water fat MRI could serve as a useful tool to quantify marrow fat content for CKD patients.

The promyelocytic leukemia (PML) protein is an important part of the PML nuclear bodies (PML-NBs) structure.PML protein is crucial for the assembly of PML-NBs and recruits more than 30 different proteins, including DAXX, ATRX, and small ubiquitin-like molecules involving SUMO to the PML-NBs region.Increased evidence has emerged that a number of different proteins is involved in regulating PML activities by post-translational modifications, such as SUMO modification, ubiquitination and phosphorylation.Here, we review recent studies on the combination of PML and different proteins in the process of apoptosis, replicative senescence and DNA damage response.

Objective To evaluate whether visual exploration therapy could lead to the recovery of cognitive function and activities of daily living (ADL) of stroke patients with unilateral neglect. Methods From January, 2012 to June, 2014, 24 stroke patients with unilateral neglect were randomly divided into control group (n=12) and observaton group (n=12). The control group received conventional rehabilita-tion therapy, and the observation group received visual exploration therapy additionally. They were evaluated with Mini-Mental State Exami-nation (MMSE), Montreal Cognitive Assessment (MoCA), modified Barthel index (MBI) and Chinese Behavioral Inattention Test-Hong Kong version (CBIT-HK). Results All the scores improved after treatment in both groups (t>5.375, P<0.001), and were higher in the obser-vation group than in the control group (t>2.120, P<0.05), except MMSE (P>0.05). Conclusion Visual exploration therapy could not only fa-cilitate the recovery of unilateral neglect in stroke patients, but also improve their cognitive function and activities of daily living.
