BACKGROUND:The effect of proximal femoral anti-rotation nail fixation in repair of intertrochanteric fracture is better than the other fixation materials. Unarmed inserting guided needle plays an important role for the quality of intertrochanteric fracture fixation. At present, there have been short of fast and accurate methods for inserting femoral canal guided needle from trochanter. OBJECTIVE:To investigate the operating skil s and application value of unarmed inserting guided needle in the process of proximal femoral anti-rotation nail Ⅱ fixation in repair of intertrochanteric fracture. METHODS:Standard operating procedures of guided needle inserting were established. The location of the guided needle was correct or was not judged through discriminating the feeling of inserting into the tip of femoral canal guided needle from trochanter. Slight resistance prompted that guided needle was in correct position. The guided needle closed to the medial femoral cortex and moved downward in the medul ary cavity. The guided needle was confirmed in the correct position by the perspective of C-arm in positive side position. This process was just one lateral perspective. Smoothly without resistance prompted that if the guided needle was out of the medul ary cavity, the direction of the inserting needle needed to be changed, without perspective. The resistance would be large if the needle tip piercing the medial femoral cortical bone, at this moment, the direction of the needle needed to be adjusted;or was blocked by malreduction of fracture or the free fracture block off the medul ary cavity;at this moment, fracture ends needed to be further restored. The surgery time, the time required to complete the guided needle inserting, the amount of bleeding, weight-bearing ambulation time and complications of 19 patients with intertrochanteric fracture treated by proximal femoral anti-rotation nail Ⅱ fixation were statistical y analyzed. RESULTS AND CONCLUSION:The average completed time for internal fixation was 45 minutes, the average desired time for guided needle inserting was 80 seconds, the average blood loss was 100 mL. There was no wound infection, or pressure sore formation. The shimoji time was an average of six weeks after treatment. Al patients were fol owed up for 4-9 months. Three patients needed crutches to walk before treatment, and after three months of treatment, they returned to the pre-exercise levels of injury. These results suggest that the procedure of unarmed inserting the guided needle provides guidance for the quick and correct completion of needle inserting, so as to enhance the internal fixation quality of proximal femoral anti-rotation nail Ⅱ in repair of intertrochanteric fracture, with a high reliability. It can significantly reduce the number of perspective, shorten surgery time, reduce the amount of bleeding and reduce complications.

Objective To compare the effects of semi conductor laser nasal cavity irradiation with He Ne laser intravenous irradiation therapy on patients with brain lesion. Methods Ninety six cases of cerebral infarction(CI), traumatic brain injury(TBI) were randomly divided into semi conductor laser group (group A, n =50, ?=650nm , 2.4mW, 30mins/nasal cavity), He Ne laser group (group B, n =46, ?=632.8nm, 2.5mW, 40mins/ intermedia cubiti vein or basilic vein). The changes of the blood lipids, hemorheology parameters, scores with Fugl Meyer movement scale and Barthel index assessment were compared after the semi conductor laser and He Ne laser irradiation. Results After laser irradiation,The CHOL, TG, LDL, ESR and HCT were significantly reduced in both groups( P 0.05). The brain damage area was reduced in all the patients as revealed by CT examination. Conclusion The influence of the two kinds of laser irradiation therapies is similar when applied in patients with brain injury. But semi conductor laser nasal cavity irradiation is a simple, safe, inexpensive therapy for the patients.

METHODS 27 cases with stroke or traumatic brain injury affecting the muscles of lower extremity were selected to receive local intramuscular injection. The injected dose is between 50～100 U?(muscle) -1. All patients received rehabilitation therapy that focused on walking training. Patients were assessed at entry, and 2, 4 weeks post-treatment. The muscle tone was assessed by the modified Ashworth Scale, the changes of time-distance parameters was measured by footprint gait analysis. The correlation relationship between muscles tone and gait parameters was analysed. RESULTS Compared to pretreatment values, the total muscles spasticity, walking distance, and speed were significantly improved in all groups respectively, decrease in the modified Ashworth Score (P

Objective: To evaluate the status of loneliness, the influential factors and the relationship between loneliness and family function among bereaved parents in disaster area of 5.12 Earthquake and to provide basis for mental and family reconstruction for those people suffering from the Earthquake. Methods: A total 190 bereaved parents in disaster area of 5.12 Earthquake were enrolled for an across-sectional study. A face-to-face survey was conducted by following scales: General Data Scale, University of California at Los Angels Loneliness Scale, Emotional and Social Loneliness Scale and Family APGAR Index. Results: hTe score of loneliness ranged from 24 to 69 (mean=43.58, SD=9.61), the score of emotional loneliness ranged from 5 to 24 (mean=11.95, SD=3.60) while the social loneliness ranged from 6 to 24 (mean=13.99, SD=3.69). hTe scores of loneliness, social loneliness and emotional loneliness were all increased among bereaved parents compared to people without loss of their child. The results of multivariate analysis showed that family function and status of fertility significantly impacted the loneliness (P<0.05). Furthermore, there was negative correlation between family function and the loneliness, social loneliness and emotional loneliness (P<0.05). Conclusion: The bereaved parents in disaster area of 5.12 Earthquake showed higher level of loneliness. The better of family function indicated the less of loneliness in bereaved parents. Measures should be taken to promote mental and family reconstruction for such people, including providing effective skills to improve emotional communication and family function and offering technical support for having another baby.

Objective To evaluate the post-puncture complications in children,and to evaluate the difference in the occurrence rate of headache and backache between patients who had 1 hour of supine recumbency and those who had 4 hours of supine recumbency,to provide evidence for the standardized lumbar puncture (LP) procedure of children.Methods Inpatients who were older than 3 and had diagnostic LP in the course of their treatment between Nov.2012 and Apr.2013 were enrolled.The LP was performed by the same investigator under the standardized institutional guideline for LP and the information of number of LP attempts,duration of LP and cerebrospinal fluid (CSF) drainage volume were recorded.After the procedure,all the children were randomly assigned into 2 groups:the test group had supine recumbency for 1 hour after LP,and the control group had it for 4 hours.For the first 5 days following LP,reports of headache and backache were recorded by another physician who didn't participate in this study.The difference in the occurrence rate of headache and backache between test group and control group was assessed by the chi-square test or Fisher's probabilities in 2 × 2 table.And a Logistic regression analysis was performed to assess the risk factors for the occurrence of the headache and backache.Results The overall frequency of headache was 4.6％ (4/87 cases).The frequency of headache was not significantly different between the test group (2.4％) and control group (6.7％) (P =0.617).And the overall frequency of backache was 19.5 ％ (17/87 cases),and it was not significantly different between the 2 groups (test group:21.4％,control group:17.8 ％,P =0.668).In a Logistic regression analysis,age (P =0.011,OR:6.884,95％ CI:1.398-33.906) and the previous history of lumbar puncture (P =0.018,0R:0.126,95 ％ CI:0.026-0.618) were significant risk factors for the occurrence of backache.The risk of backache in children with more than 2 times of LP was decreased.And the risk was higher in the children older than 6 years than those younger than 6 years.Conclusions Headache and backache were the most frequent post-puncture complications in children.There was no difference between short duration (1 hour) of supine recumbency and long duration (4 hours) in preventing the occurrence of headache and backache after LP.

Objective To investigate clinical signifieances of serum levels of vascular endothelial growth factor (VEGF) in patients with diffuse large B-cell lymphoma (DLBCL) and to analyze the relationships with international prognostic index (IPI). Methods Serum levels of VEGF were measured by ELISA in 26 cases with newly diagnosed DLBCL and 9 cases with relapsed DLBCL. The clinical data of 26 patients were collected. According to the IPI, 26 patients were divided into two group: low risk group (IPI＜2) and moderate to high risk group (IPI≥2). Results Compared with the normal controls, newly diagnosed and relapsed DLBCL had significantly higher VEGF serum levels (P ＜0.01). In the patients responding to CHOP or RCHOP regimen a significantly decrease in VEGF serum levels occurred, while in the patients who did not achieve complete remission(CR) there was no significant decrease. Furthermore, pretreatment serum levels of VEGF were significantly lower in CR group than in partial remission (PR) and no remission (NR) group. In addition, serum levels of VEGF were significantly elevated in the high risk group than those at the low risk group(P＜0.01). Conclusion The serum levels of angiogenic factor VEGF are related to the development and progression of DLBCL. The VEGF combined with IPI can be used for evaluating the prognosis of DLBCL.
