Conclusion: The questionnaire has good reliability and validity, and meets the need of psychometrics.

OBJECTIVETo compare the efficacy between eccentric fixation and internal fixation for treatment of intertrochanteric fractures of femur,to provide a theoretical basis for the selection of the treatment method of the intertrochanteric fractures of femur.

METHODSFrom February 2007 to January 2010,82 patients with femoral intertrochanteric fracture were treated by internal fixation including 39 cases of eccentric fixation involving 23 males and 6 females, aged from 41 to 81 years old with an average of (62.68±10.69), using the DHS or proximal femoral locking plate; 43 cases of intramedullary fixation involving 15 males, 28 females,aged from 43 to 78 years old with an average of (62.60±8.37),using PFN or PFNA fixed. The surgical incision length, operative time, blood loss and postoperative Harris score between two groups were compared.

RESULTSThe wound of two groups were primary healing without operative complications. All cases received follow-up for an average time of 18.3 months (12 to 28 months). The incision length, operative time and blood loss had a statistically significant difference between two groups (P<0.05). Harris scores of hip joint function at 1 month after operation had statistically significant difference between two groups (P<0.05), and Harris scores at 12 months after operation had no statistical significance difference between two groups. The rate of excellent and good was 89.7% in eccentric fixation group and 90.7% in intramedullary fixation group,the difference was not statistically significant (t=0.0613, P>0.05). In eccentric fixation group, there was 1 case of fracture nonunion with DHS loose and ensuing hip varus deformity. In intramedullary nail fixation group, there was no anti-rotation out,distal intramedullary nail of femoral refracture occurred in 1 case.

CONCLUSIONTwo treatment methods for the treatment of femoral fractures had a good therapeutic effect,but the intramedullary fixation had shorter operative time and less blood loss than the eccentric fixation,it prior to apply to osteoporosis and unstable femoral intertrochanteric fractures.

Objective:To investigate the status of professional identity among student nurses and explore its influential factors.Methods:A total of 1,302 student nurses from 3 universities of different levels in Shaanxi Province were selected using stratified and cluster random sampling method and investigated by adopting Professional Identity Questionnaire for Nurse Students (PIQNS).Results:Student nurses in Shaanxi Province scored (57.56 ± 12.55) in professional identity,of which the lowest was independence of career choice in the 5 dimensions.It showed that educational status,gender,and the reasons to choose nursing specialty correlated to student nurses' professional identity (P ＜0.05).Conclusions:The professional identity of student nurses especially for the undergraduate nurses is not high,which should cause the attention of the nursing educators and nursing managers to stabilize nursing team.

Objective To explore the biomechanical characteristics of the pharynx in patients with aspiration after radiotherapy for nasopharyngeal carcinoma (NPC).Methods Clinical data on NPC patients with dysphagia admitted between July 2011 and June 2015 were retrospectively analyzed.Twenty-three patients were found who had received videofluoroscopic swallowing studies (VFSSs) and whose pharyngeal pressure and upper esophageal sphincter (UES) relaxing were tested using high-resolution solid-state manometry (HRM).The cases were divided into an aspiration group and a non-aspiration group according to the VFSS results.Differences in biomechanical parameters between the 2 groups when taking food of different viscosity were compared.Results Patients with aspiration had significantly higher UES residual pressure when taking thick liquids (20.1± 14.3 mmHg) and paste (18.0± 14.3 mmHg) than patients not aspirating (9.3±9.2 mmHg and 7.2±8.9 mmHg for thick liquid and paste respectively).But no significant difference in average pharyngeal pressure between the two groups was observed.Conclusion Aspiration after radiotherapy may be correlated with increased UES residual pressure.

Objective To report two cases of familial Gitelman syndrome and literature review regarding the updates of relevant genes,classification,treatment,and prognosis.Methods The clinical data of two sisters with Gitelman syndrome were retrospectively analyzed.Results Their blood pressures were within normal range.Hypokalaemic alkalosis,hypomagnesemia,and hypocalciuria were corrected almost completely after three days of intravenous magnesium and potassium infusion,spirolactone and indometacin.However,the maintenance of normal potassium was unsuccessful over one year.Conclusion Hypokalaemic alkalosis,hypomagnesemia,and hypocalciuria were normalized in Gitelman syndrome.There was some debate in regard to using PGE2 synthetase inhibitors.Tolerance of long-term medication will be the big challenge for curative effect.

The volatile components of roots and stems of Zanthoxylum nitidum were investigated by supercritical fluid carbon dioxide extraction (SFE-CO2) and gas chromatography-mass spectrometry(GC-MS). Thirty-one and fifty-one compounds were identified in the supercritical extracts from roots and stems of Z. nitidum, respectively, and total twenty-seven compounds were the common constituents. Among them, the major constituents in root and stem supercritical extracts were spathulenol (18.49 and 26.18%), n-hexadecanoic acid (14.24% and 12.79%), ar-tumerone (6.95% and 8.88%), oleic acid (8.39% and 5.71%) and hexanoic acid (4.39% and 7.78%). The in-vitro MTT assay showed that the volatile components of roots and stems of Z. nitidum did not exhibited any cytotoxic activity against human cancer Huh-7 and normal IEC-6 cells. These results indicated the same nature of the volatile constituents in the root and stem of Z. nitidum. This investigation may provide further evidence for expansion of medicinal parts of Z. nitidum.

Objective To investigate the change of the neutrophil apoptosis and neutrophil respiratory burst in the patients and the effect of ulinastatin on the apoptosis of neutrophil and respiratory burst of neutrophil during cardiopulmonary bypass (CPB). Methods Sixty-two patients undergoing valve replacement with CPB were randomly divided into two groups: ulinastatin group (U group, 31 cases) and control group (C group, 31 cases). In U group patients received ulinastatin after induction of anesthesia. In C group patients received equal volume of normal saline, instead of ulinastatin. Arterial blood was obtained before operation (T1), 30 min after the start of CPB (T2), 30 min after the termination of CPB (T3). The apoptosis of neutrophil and respiratory burst of neutrophil were measured by flow cytometer. The level of superoxide dismutase (SOD) and malondialdehyde (MDA) were measured by kit. Results In C group, compared with T1 [(66.57±5.93)%], the rate of the apoptosis of neutrophil was significantly decreased at T2[(55.37±3.51)%] and T3 [(48.92±4.21)%] (P<0.05). And in U group, compared with T1 [(73.57±7.94)%], the rate of the apoptosis of neutrophil was significantly decreased at T2 [(68.34±4.92)% ] and T3 [(62.13±4.76)%] (P<0.05), And it reached to the minimum at T3. The rate of the neutrephil apeptosis was significantly lower in C group than that in U group (P<0.05). The respiratory burst of neutrophil increased significantly after the start of CPB and reached to the peak at T3[C group (1422.50±89.75) MCF,U group (1156.52±93.20) MCF]. The respiratory burst of neutrophil in U group was significandy lower than that in C group at T2 and T3 (P<0.05). The vitality of SOD decreased significantly after the start of operation in the two groups (P<0.05). The level of MDA increased significantly after the start of operation in the two groups, and reached to the peak at T3. The vitality of SOD in C group was significantly lower than that in U group at T3 (P<0.05). The level of MDA in C group was significantly higher than that in U group at T3 (P<0.05). Conclusions The rate of neutrophil apoptosis decreased and the respiratory burst of neutrophil increased during CPB. By improving the apoptosis of neutrophil and reducing the respiratory burst of neutrophil, ulinastatin can inhibit inflammatory reaction during CPB. Meanwhile, ulinastatin can improve the vitality of SOD and reduce the level of MDA. In conclusion, ulinastatin has a significant protective effect during CPB.

BACKGROUND:Several studies have reported that quercetin can inhibit the proliferation and migration but promotes apoptosis of tumor cel s. OBJECTIVE:To explore the effect of quercetin on the proliferation and apoptosis of glioma stem cel s and the signal pathway involved. METHODS:Glioma stem cel s were isolated by immunomagnetic beads and treated in culture medium containingdifferent concentrations of quercetin (0, 25, 50, 100μmol/L). Cel proliferation was measured by MTT and apoptosis measured by flow cytometry at 48 hours after culture. The expression levels of Bcl-2, Bax and survivin, which are related to apoptosis, were detected by western blot. The expression of proliferating cel nuclear antigen (PCNA), which is related to proliferation, was also detected by western blot. The expression of STAT3 and p-STAT3 was also determined by western blot. RESULTS AND CONCLUSION:(1) Compared with the control (0μmol/L) group, quercetin inhibited the proliferation of glioma stem cel s in a dose-depended manner (P<0.05). With the increase of the concentration of quercetin, the expression of PCNA was increased (P<0.05). (2) Quercetin induced apoptosis of glioma stem cel s dose-dependently (P<0.05). With the increase of the concentration of quercetin, the expression of Bcl-2 and survivin was decreased, while the expression Bax was increased. (3) Quercetin could also inhibit phosphorylation of STAT3 dose-dependently, but the level of STAT3 was not changed. To conclude, these results show that quercetin could inhibit the proliferation of glioma stem cel s and promote apoptosis via the STAT pathway.

Objective To compare the efficacy of 18F-FDG PET/CT, 99Tcm-MDP bone scintigraphy (BS), and combination of the two techniques (PET/CT + BS) for detecting bone metastasis by ROC curve analysis. Methods All 296 patients with various cancers, who underwent both 99Tcm-MDP BS and 18F-FDG PET/CT within two months, were retrospectively analyzed. These images were interpreted according to 5-point scale (0: definitely negative, 1: probably negative, 2: equivocal, 3: probably positive, 4:definitely positive for bone metastasis), and the scale of PET/CT + BS was the sum of PET/CT and BS. In light of the confirmed diagnosis derived from pathology or follow-up, ROC curve analysis was performed.The area under the ROC curve (AUC) was compared by z-test. Results Of 296 cases, 61 (20.6%) were confirmed as bone metastases and 235 (79.4%) were negative. The AUC were 0. 919 (95% confidence interval (95% CI) :0. 867 - 0. 971) for BS, 0. 949 (95% CI: 0. 906 - 0. 991) for PET/CT, and 0. 994 (95% CI: 0.988-0.999) for PET/CT + BS, rctrospectively. The AUC of PET/CT + BS was statistically significantly larger than that of BS (z=2. 866, P=0.004) or PET/CT (z =2.027, P=0.043), while the AUC of PET/CT was larger than that of BS, but no statistically significance (z = 0. 881, P = 0. 378) was showed. The optimal sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value(NPV) were 90. 2% (55/61), 85. 1% (200/235), 86. 1% (255/296), 61. 1% (55/90), 97. 1%(200/206) for BS, 88.5% (54/61), 97.0% (228/235), 95.3% (282/296), 88.5% (54/61), 97.0% for PET/CT, and 98.4% (60/61), 95.7% (225/235), 96.3% (285/296), 85.7% (60/70) for PET/CT + BS,respectively. The specificity (χ2 = 19.862, P<0. 001), accuracy (χ2 = 23. 361, P<0.001) and PPV (χ2 =11. 791, P =0.001) of PET/CT + BS were significantly higher than those of BS, the sensitivity of PET/CT +BS was significantly higher than that of PET/CT (χ2 =4.167, P=0.031). Compared with BS, PET/CT had a higher specificity (χ2 = 19.600, P<0. 001), accuracy (χ2 = 13. 755, P <0. 001), PPV (χ2 = 13. 608, P <0. 001), but their sensitivity showed no statistically significant difference (χ2 = 0, P = 1. 000). Conclusions The efficacy of 18F-FDG PET/CT for detecting malignant bone metastasis was superior to that of 99Tcm-MDP BS alone. The detection ability can be obviously improved by combination of the two techniques.
