Objective To study wether dezocine (DZ) can attenuate neuropathic pain in rats and to investigate its mechanism.Methods Neuropathic pain was induced by tight ligation of the left L5 spinal nerve of the male SD rats. 24 Spinal nerve ligation (SNL) model rats were randomly divided into three groups:the first group (saline group, n=8), rats were given intraperitoneal injection of 1ml of saline 14 days after SNL surgery; the second group (dezocine group, n=8), rats were given intraperitoneal injection of 5mg/kg of dezocine in 1ml saline 14 days after SNL surgery;the third group (morphine group,n=8),rats were given intraperitoneal injection of 5 mg/kg of morphine 14 days after SNL surgery. Results Intraperitoneal injection dezocine and morphine had significant analgesic effect in neuropathic pain rats. This analgesic effect lasted for 4-6 hours.Continuous injection of morphine for 3 days produced significant tolerance, while continuous injection of dezocine for 7 days still had significant analgesic effect on neuropathic pain. Conclusion Intraperitoneal injection of dezocine and morphine can attenuate SNL neuropathic pain, continuous injection of morphine for 3 days can produce significant tolerance, while continuous injection of dezocine for 7 days still has significant analgesic effect on neuropathic pain.

Objective To suty the MRI manifestations of juvenile acute articular cartilage injury of the knee joint.Methods MRI findings of cartilage,subcartilage low signal line and subcarilage bone were analysed retrospectively in 53 juvenile patients (ranged in age from 4~27 years) with acute articular cartilage injury confirmed by arthroscopy.Results Sixty-nine cartilage injuries were showed by MRI in 53 patients,including patellas in 25,femoral lateral condyles in 22,femoral medial condyles in 11,trochlea of the femur in 2,and tibial plateau in 9.Acute articular cartilage injury appeared as pure cartilage fracture in 46, including complete split of the cartilage in 22 sites,partly split of the cartilage in 20 sites,and fissur-like fracture in 4 sites.Osteochondral fracture were observed in 23 sites,including avulsion fracture in 13 and osteochondral subsided in 10.Articular cartilage loose bodies and osteochondral loose bodies were found by MRI in 6 and 13,respectively.Conclusion MRI is the best non-invasive method for studying cartilage injury.

Objective To investigate the clinical efficiency of branch artery of the sural medial gastrocnemius muscle flap combine with sural nerve nutritional vessel axial.Methods From February 2006to March 2010,according to the position and size of the soft tissue defects,the muscle flap combined with branch artery of the sural medial gastrocnemius and sural nerve nutritional vessel axial were desingned and obtained to repair 7 cases of sofi tissue defects of the upper-region of the tibial.The flap size ranged from 8.0 cm × 8.0 cm to 12.0 cm × 10.0 cm.The vessel pedicle of branches ranged from 1.8-3.0 cm.The distribution of the vessel pedicle of branches ranged from 10.0-17.0 cm on the distant popliteal fossa,and ranged from 2.0-5.0 cm on the back of medial line.Results The outline and function were satisfactory during 6-15 months follow-up.Conclusion The blood supply of this flap is reliable without sacrifice of major arteries.Flap elevation is easy.It can transfer to a long distance and can repair large skin defects.It is very useful in repairing upper-region of the tibial large soft tissue defect.

Objective To investigate the antireflux effect of esophagogastrostomy combined with modified Nissen fundoplication after esophageal middle cancer resection.Methods Eighty-two patients with esophageal middle cancer were divided into 2 groups by random digits table method,41 cases underwent esophagogastrostomy with a stapler only (control group),41 cases underwent esophagogastrostomy with stapler combined with modified Nissen undoplication (observation group).Three months after surgery,the patients of the 2 groups completed the research of EORTC QLQ-C30 questionnaire,and examined with esophageal manometry and gastroscopy.Results There was no statistical difference in incidence of postoperative complication between the 2 groups (P ＞ 0.05),death was not found during peroperative period.The scores of heart burn and regurgitation in observation group [(13.2 ± 6.1) and (16.9 ± 3.9) scores] were significantly lower that those in control group [(25.6 ± 7.2) and (26.6 ± 4.2) scores],there were statistical differences (P ＜ 0.05),but there was no statistical difference in score of dysphagia between the 2 groups (P ＞ 0.05).The resting pressure of anastomotic site in observation group [(3.5 ± 2.3) mmHg,1 mmHg =0.133 kPa] was significantly higher than that in the stomach [(2.7 ± 2.1) mmHg],there was statistical difference (P＜ 0.05).The DeMeester score was (54 ± 32) scores,control group was (141 t 84) scores,there was statistical difference (P ＜ 0.05).The incidence of reflux esophagitis in observation group was 48.8％(20/41),in control group was 75.6％(31/41),there was statistical difference (P ＜ 0.05).Conclusions Esophagogastrostomy combined with modified Nissen fundoplication after esophageal middle cancer resection significantly increases the pressure at the anastomotic site,thus reduces the extent of gastroesophageal reflux,which leads to the reduction of the extent of reflux esophagitis and the improvement of the quality of life.

BACKGROUND:Psychological disorder and behavior disorders can affect the development of behavior and personality in children.OBJECTIVE:To investigate the behavior disorders and the personality in children with tic disorders (TD).DESIGN:A comparative investigation between TD children and the healthy controls.SETTING:It was conducted at the Department of Pediatrics,Daqing Oil Felid General Hospital in Heilongjiang ProvincePARTICIPANTS:Totally 110 outpatients including 92 males and 18females, diagnosed as TD at the Department of Pediatrics, Daqing Oil Felid General Hospital,were selected (TD group) from February 2003 to December 2004.According to the clinical manifestations,they were divided into transient tic disorder group (46 cases),chronic motor/vocal tic disorder group (34 cases) and Tourette Syndrom (TS) group(30 cases).All the patients were newly diagnosed without any medication and intracranial organic diseases. Meanwhile,30 children with normal physical examination findings, between the ages of 7 and 14,24 males and 6 females, were selected as controls. Informed consents were obtained from guardians of all the participants.used to measure the children's social skills and behaviors (It contains a 113-item behavior problems scale. According to the children's ages,the items were classified into 9 factors,including somatic complains,poor social skills,compulsions,undisciplined,hyperactivity,Asperger syndrome,immaturity,hostility and aggressiveness.The scores of referring items constitute the total score of each factor).Comparison of these scores between patients and healthy controls is helpful to determine if a factor in affected children is abnormal. The closer the relationship between the patients and the controls is, the less behavioral problems Personality Questionnaire (EPQ) was adopted in this study to evaluate the personality in the patients compared to healthy controls.{There were four major dimensions of personality including introversion/extraversion,neuroticism,psychoticism and validity questionnaire (construct validity).When the validity score was over 70,it represented that the EPQ was invalid.An over-61.5 neuroticism score represented an apparent neuroticism tendency. Once the neuroticism score and introversion/extraversion score were over 56.7,mental instability or instable tendency could be suspected. When introversion/extraversion score was over 56.7and the neuroticism (extraversion) score was less than 43.3,it represented a sanguine personality or such tendency. When both of the neuroticism score and introversion/extraversion score were less than43.3 (introversion),it revealed a phlegmatic personality or such tendency. And when the introversion/extraversion score was less than43.3 with neuroticism score over 56.7,it represented a melancholic personality or such tendency.}MAIN OUTCOME MEASURES:Comparison of Achenbach's CBCLand EPQ between patients and healthy controls .RESULTS:Totally 110 TD patients and 30 healthy children completed the control group (t=3.12-8.60, P ＜ 0.01).The hyperactivity score in the transient tic group was significantly higher than that in the control group (t=2.01, P ＜ 0.05). In the chronic motor tic disorder group and the TS group,the scores of depression/anxiety,poor social skills,compulsions,social withdrawal,hyperactivity and aggression were all higher than those in the control group(t=2.11-7.65, P ＜ 0.05-0.01).In all of these three TD groups, score factors relating to social functions,such as movements, social skills and school life were apparently lower than those in the control group (t= 1.97-7.31, P ＜ 0.05-0.01).(t=2.76-4.32, P ＜ 0.05-0.01), while the score of validity questionnaire was lower than that in control group (t=3.49-6.38, P ＜ 0.05).CONCLUSION:It reveals that TD patients have many behavioral problems,personality defects and poor social skills. Of all the TD groups,the transient tic group has a higher occurrence rate of disease and only one abnormal factor, hyperactivity. While,the chronic motor tic disorder group and the TS group have more abnormal behavioral factors.

Objective To analyze the pattern of normal bone marrow on whole body diffusionweighted imaging (WB-DWI) and its influence factors.MethodsA total of 98 healthy volunteers (male 47 and female 51). All volunteers underwent WB-DWI at 1.5 T MR scan. The ADC value,the signal intensity on DWI obtained with a b value of 800 s/mm2 ( SIDWI ),and the signal intensity on short time inversion recovery images ( SISTIR ) of thoracic vertebrae,lumber vertebrae,bilateral head of femur,bilateral neck of femur,bilateral superior segment of femur,bilateral inferior segment of femur,bilateral ilium,bilateral head of humerus,bilateral scapula were measured and compared with ANOVA test and StudentNewmar-Keuls test.The normal appearance of bone marrow on WB-DW[ was assessed. The relationship between the SIDwI and the ADC,and the SIDWI and the SISTIR of bone marrow were analyzed.The ADC of bone marrow between male and femaIe were compared. Spearman correlation analysis was performed for different age groups.Results( 1 ) Bone marrow signal intensity was different among 98 healthy volunteers.Bone marrow in 69 healthy volunteers (female 24,male 45 ) showed low to intermediate signal intensity,whereas in the remaining 29 healthy volunteers (female 27,male 2) showed high signal intensity.(2) The SIDWI of thoracic vertebrae ( median 44.54),lumber vertebrae ( median 35.01 ),head of femur ( median 13.61 ),neck of femur ( median 16.00),superior segment of femur ( median 21.45 ),ilium ( median 25.77),head of humerus (median 18.35),scapula (median 36.12) was positively correlated with the ADC [ (0.55 ±0.08) × l0-3,(0.53 ±0.08) × 10-3,(0.30 ± 0.10) × 10-3,(0.42 ± 0.16) × 10-3,(0.74±0.14) ×l0- 3,(0.49±0.10) ×10-3,(0.36±0.13) ×10-3,(0.49±0.11) × 10-3mm2/s]and the SISTIR ( median 61.81,64.99,53.27,69.08,73.10,66.35,73.16,79.81 ),r =0.513 and 0.695,0.741 and 0.764,0.443 and 0.489,0.641 and 0.656,0.510 and 0.648,0.475 and 0.715,0.366 and 0.446,0.437 and 0.739 ;P ＜ 0.01. (3) There was significant difference of the ADC of bone marrow in different bone,F =138.69,P ＜ 0.01. Student-Newman-Keuls test revealed that no significant difference was found in the ADC between thoracic vertebrae and lumbar vertebrae,ilium and scapula,head of humerus and inferior segment of femur ( P ＞ 0.05 ),and significant difference was found in the ADC values between the remaining two groups ( P ＜ 0.05 ). The bones associated with decreasing ADC values were superior segment of femur,thoracic vertebrae and lumber vertebrae,ilium and scapula,neck of femur,head of humerus,head of femur and inferior segment of femur. ( 4 ) The ADC values of bone marrow of female subjects in thoracic vertebrae [ (0.59 ±0.07) × 10-3 mm2/s],lumber vertebrae [ (0.58 ±0.06) × 10 -3 mm2/s],head of femur ( median 0.33 × 10 -3 mm2/s),neck of femur ( median 0.53 × 10 -3 mm2/s),superior segment of femur ( median 0.81 × 10-3 mm2/s),inferior segment of femur ( median 0.32 ×10-3 mm2/s),ilium [ (0.52 ± 0.09 ) × 10-3 mm2/s ],head of humerus (median 0.42 × 10-3 mm2/s),scapula [ (0.53 ± 0.09) × 10-3 mm2/s] were significantly higher than those of male subjects [ (0.51 ±0.07) × 10-3,(0.48 ±0.07) × 10-3,median 0.23 × 10-3,median 0.31 × 10-3,median 0.66 × 10-3,median 0.23 × 10-3,(0.46 ±0.10) × 10-3,median 0.27 × 10-3,(0.45 ±0.11 ) × 10 3mm2/s].(5)There was significant negative correlation between the ADC values of bone marrow and age in thoracic vertebrae,lumber vertebrae,head of femur,neck of femur,superior segment of femur,ilium,head of humerus for female subjects,r =-0.549, -0.629, -0.329, -0.524, -0.338, -0.548 and -0.416,respectively,P ＜ 0.05.There was no significant correlation between ADC values and age in inferior segment of femur and scapula for female subjects and all the regions for male subjects ( P ＞ 0.05 ).Conclusions The ADC and the SIsTIR of bone marrow correlates with the SIDW1.The ADC values of bone marrow is affected by age and sex,and is different for different bones.

Rectal diverticulum is rarely seen in clinical practice.Perforation or rupture of rectal diverticulum with symptoms and signs of acute diffuse peritonitis makes it easily be misdiagnosed as appendicitis,rectal neoplasms,intestinal obstruction and other abdominal diseases.In this article,a retrospective analysis of the clinical data of one patient with extraperitoneal pneumatosis caused by perforation of rectal diverticulum was performed to investigate the diagnosis and treatment of the disease.

Objective Because of high incidence rate of complicated postoperative abdominal infections in abdominal injuries and difficulty in their clinical diagnosis and treatment,this article aimed to investigate the mechanism and the surgical tactics for this kind of complication.Methods Totally 48 abdominal-injured cases of postoperative complicated abdominal infections in our hospital from July 2005 to December 2010 were reviewed.These patients (Male 30,Female 18) aged 16-70 (mean 38) years.There were 20 cases of simple abdominal injuries,and 28 cases of multiple injuries ( ISS 16 - 52,mean 24.42).The complicated postoperative abdominal infections included abdominal incision infections (25cases),intra-abdominal infections( 18 cases) and retroperitoneal infections(5 cases).Forty cases were transferrted from other hospitals to our hospital 2 - 76 days after trauma.16 of which underwent exploratory laparotomy at other hospitals after injury,and 8 cases were directly transferred to our hospital after injury.Results All patients finally had a definite diagnosis by abdominal checking(26 cases),paracentesis(5 cases),ultrasound and CT scan ( 12 cases),and PET/CT scan (5 cases)in our hospital,and were confirmed by cultiure of pathogenic bacteria.The treatment included vacuum sealing drainage (VSD) (25 cases),percutaneous imaging- guided abdominal abscess drainage(13cases) and re-laparotomy ( 10 cases).Successfull treatment was achieved in 46 patients,death in 2 patients.The causes of death consisted of 1 case of severe craniocerebral injury,1 case of MODS.Conclusions Complicated abdominal infections often occurs after the operations of abdominal injuries.attentively abdominal checking,paracentesis,and CT scan repeatedly were proofs to benefit the finally diagnosis.VSD therapy is a simple and effective method for abdominal incision complication,and dynamic CT scan and prompt exploratory laparotomy can improve patients' prognosis.

Objective To investigate the feasibility of non-invasive quantitative evaluation of portal pressure (Pp) by contrast enhanced ultrasonography (CEUS).Methods 18 portal hypertension patients (PTH group) were performed with CEUS within one week before splenectomy and pericardial devascularization,and 20 healthy volunteers as controls were recruited in this study (control group).Hepatic-right kidney sectionwas chosen to calculate the area under curve of portal vein/hepatic artery (Qp/Qa) and the perfusion intensity of portal vein/hepatic artery (Ip/Ia) through time intensity curves (TIC) of liver parenchyma generated from CEUS images.Pp was measured by intra-operative mesenteric vein catheter,and the correlation betweenPp and Qp/Qa,Ip/Ia were analyzed by Pearson correlation test.Results The levels of Qp/Qa and Ip/Ia in the PTH group were 2.28 ± 0.66 and 0.35 ± 0.14 respectively,which were both significantly declined than that in the controlgroup (5.72 ± 3.69 and 1.97 ± 0.17).In the PTH group,the correlation coefficient were-0.747 and-0.617,and the linear regression equations were Y =-83 X + 5.013 andY =-15X + 0.837,which indicated that Qp/Qa and Ip/Ia had significant correlation with Pp.Conclusions CEUS parameters,including Qp/Qa and Ip/Ia,are significantly correlated to Pp in portal hypertension patients,which indicate that CEUS could be a new non-invasive clinical method for evaluating Pp.
