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.

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 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.

ObjectiveTo investigate the feasibility and effect of complete thoacoscopes and laparoscopes combination operation for thoracoabdominal injuries.MethodsFrom March 2007 to March 2011,the clinical data of 36 patients (observation group) with thoracoabdominal injuries who were performed with complete thoracoscopes and laparoscopes combination operation were analyzed retrospectively,and compared with 36 patients (control group) treated with traditional standard operation in the same period.The intraoperative and postoperative situation was compared between two groups.ResultsAll the patients in observation group were successfully performed by complete endoscopic surgery.There were no operative mortality and complications related to operation,such as diaphragmatic hernia,delayed hemopneumothorax.The operative time of observation group was (98 ±38 ) min,operative blood loss was ( 120±45 ) ml,drainage flow within 24 h was(230 ±55) ml,drainage tube duration was(5 ±2) d,postoperative pain vasual analogue scale (VAS) score was (3.31±0.87) scores,hospitalization cost was ( 1 2.3±7.6) thousand yuan,postoperative recovery time of intestinal function was (2.29±1.02) d,hospital stay was ( 10±3 ) d.Those values of control group were respectively ( 135±31 ) min,(220±30) ml,(400±160) ml,(9±3) d,(6.82±1.67) scores,(23.4±8.5) thousand yuan,(5.46 ±2.31 ) d and ( 16±2) d.There were significant differences between two groups(P ＜0.05).The occurrence rate of cardiopulmonary complication of observation group [ 11.1％(4/36) ] and control group [ 13.9％(5/36) ] had no significant difference (P＞0.05).ConclusionsComplete thoracoscopes and laparoscopes combination operation for thoracoabdominal injuries is a safe and mini-invasive treatment with quicker recovery,less cost and morereliable effect.Therefore,it deserves further clinical application.

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 analyze the dose‐effects of different doses of dexmedetomidine for sedation and sleep of the patients under epidural nerve block anesthesia .Methods A total of 82 patients undergoing elective lower limbs surgery(ASA grade Ⅰ - Ⅱ) were randomly divided into 4 different doses of dexmedetomidine groups(group 1 ,n=19 ;group 2 ,n=22 ;group 3 ,n=20;group 4 , n=21) ,under continuous epidural nerve block ,the loading dose of dexmedetomidine 0 .7 ,0 .8 ,0 .9 ,1 .0μg · kg -1 · h-1 was intrave‐nously pumped for 30 min ,then pumped at a rate of 0 .7 ,0 .8 ,0 .9 ,1 .0 μg · kg -1 · h-1 in the group 1 ,2 ,3 and 4 respectively .If any patient in 4 groups fell asleep at less than half an hour ,the loading dose was stopped and the continuous dose was changed to pump , the drug administration was discontinued at wound dressing after operation .Whether the patient falling asleep was recorded ,and the mean arterial blood pressure ,heart rate at 4 time points of 10 ,30 ,60 ,90 min after infusion of dexmedetomidine were also recorded .
