Objective To explore the prognosis impact of lymph nodes metastasis in pancreatic cancer.Methods The clinical data of 61 patients with pancreatic cancer who underwent pancreaticoduodenectomy from January 2004 to September 2011 were analyzed retrospectively.Patients were categorized into different groups by lymph nodes metastasis status,count of positive lymph nodes,location of positive lymph nodes,lymph nodes ratio (LNR) and other factors.Kaplan-Meier,log-rank and COX proportional hazard models were used to evaluate the prognostic effect.Results Median survival for the overall 61 patients was 13 months (95％ CI 9.158-16.842),with 6 months,1 year,3 years,5 years survival rates of 84.6％,47.7％,14.3％ and 9.1％ respectively.Univariate analysis showed:the median survival of patients with and without lymph nodes metastasis had statistical significant outcome (P ＜ 0.01).Patients within the first station lymph nodes metastasis had a better outcome than those lymph nodes metastasis beyond the first station (P ＜0.05).Patients with LNR ≤0.2 had better prognosis than those LNR ＞ 0.2 (P ＜ 0.01).The number of lymph nodes examined had no effect on overall survival in either nodes-positive patients or nodes-negative patients (P ＞ 0.05).The count of positive lymph nodes did not affect the prognosis in the pN1 patients (P＞ 0.05).Multivariate analysis showed:location of positive lymph nodes and LNR were independent predictors of the prognosis in the pN1 patients.Conclusions Lymph nodes metastasis status has significant effect on the prognosis of the pancreatic cancer.Location of positive lymph nodes and LNR are independent predictors of the prognosis in the pN1 patients.The number of lymph nodes examined and the number of positive lymph nodes have no effect on the prognosis of the pancreatic cancer.

Objective:To investigate the comorbid depressive symptoms,anxiety symptoms and suicide risk in people with alcohol abuse.Methods:Totally 1992 community residents were recruited by probability proportionate to size sampling.They were assessed with the Alcohol Use Disorders Identification Test (AUDIT),Depression Sub-scale(PHQ-9 )and Anxiety Subscale (PHQ GAD-7 )of Patient Health Questionnaire,and Suicide Risk Screening Scale of Mini-International Neuropsychiatric Interview (MINI).Results:The AUDIT screening positive cases was 298 (15.1%).The rates of depression symptom (53.4% vs.42.3%),anxiety symptom (35.9% vs.27.0%)and suicide risk (5.7%vs.3.2%)in alcohol abuse group were all significantly higher than that in non-abuse group (Ps<0.0 1 ).Conclusion:It is important to conduct assessment of related psychological problems in screening of alco-hol abuse,in order to provide effective intervention timely.

Anastomotic cicatricial stenosis after resection of esophageal cancer were treated by self- making electric knife through endoscipe.Fifty two cases were located in upper segment while 37 cases in middle-lowere part.Anastomotic diameter of 40 cases were less than 2.0mm,17 cases less than 3.0mm. Sixteen cases more than 3.0mm. Anastomotic stoma were incarcerated by food in 16 cases.The operatic procedure:First,the cicatricial stenosis was resected and became"*"shape by electric knife,then dilated by baloon catheter and by endoscope.sitytwo cases of stenosis were unobstrated(can swallow solid food)after one time treatment ; 11 cases each needed 2 and 3 times;1 case each needed 4 , 5 , 12 , 43and 81 times ,respec- tively. The last 2 cases were treated repeatly every 1- 3 months. The authors think that this procedure is ef- fective and safe. The technique is mastered easily and could be wildely used.

OBJECTIVETo investigate the efficacy, advantages and disadvantages of internal and external elbow joint approach and olecranon osteotomy approach for the treatment of intercondylar fracture of humerus.

METHODSFrom October 2012 to May 2016, 18 cases of intercondylar fracture of humerus were treated by operation including 12 males and 6 females with a mean age of 33.5 years old (ranged from 4 to 56 years old); 8 cases were operated by internal and external elbow joint approach, 10 cases were operated by olecranon osteotomy approach. According to AO classification, 3 cases were type C1, 8 cases were type C2, 7 cases were type C3. All patients were excluded from neurologic and vascular injuries.

RESULTSAll patients were followed up from 12 to 26 months with an average of 15 months. The incision healed well and no heterotopic ossification was found. According to the modified Cassebaum elbow function score, the result was excellence in 14 cases, good in 3 cases, fair in 1 case.

CONCLUSIONSAccording to the fracture type, the appropriate surgical approach and fixation were selected in order to get anatomic reduction. Rigid fixation, and early functional exercise is important condition for successful operation and satisfactory functional recovery in intercondylar fracture of the humerus.

BACKGROUND:Osteopontin mRNA and protein expressions are highly correlated with the severity of osteoarthritis. OBJECTIVE:To investigate the effect of osteopontin on the gene expression of aggrecan and type II colagen in the human knee osteoarthritic chondrocytes in vitro. METHODS: Chondrocytes were harvested from human osteoarthritic knees and culturedin vitro. The chondrocytes were cultured with 0 (blank control group), 0.1, 1 mg/L osteopontin, respectively, for 48 hours. Real-time PCR was employed to detect the mRNA expression of aggrecan and type II colagen. RESULTS AND CONCLUSION:After 0.1 and 1 mg/L osteopontin intervention, the mRNA expression of aggrecan and type II colagen in osteoarthritic chondrocytes was increased significantly (P< 0.05), and the mRNA expression of aggrecan and type II colagen was higher in the 1 mg/L osteopontin group than the 0.1 mg/L osteopontin group (P< 0.05). In addition, the mRNA expression of aggrecan and type II colagen was positively correlated with the concentration of osteopontin (r=0.751,P < 0.01;r=0.676,P < 0.01). These findings indicate that osteopontin up-regulates the mRNA expression of aggrecan and type II colagen in osteoarthritic chondrocytes of human kneein vitro in a dose-dependent manner.

ObjectiveTo investigate the health status and incidence of alcohol abuse of Xinjiang community residents.MethodsThrough multi-stage random sampling,1992 community residents ( 15-65years old) were assessed using socio-demographic information questionnaire,alcohol use disorders identification test (AUDIT) and self-rated health measurement scale-prior test(SHRMS).Single factor analysis and rank sum test were used to identify the incidence of alcohol abuse,the distribution of different populations,and the self-rated health status of abusers.ResultsTotally 298 cases of alcohol abuse were identified,and accordingly,the prevalence rate of alcohol abuse for general population was 15.1％ ( male 26.4％,female 4.8％ ).Key factors for alcohol abuse included male,middle-aged,well-educated,at work,administrative work,high income levels and large number of household.The differences among groups were statistical significant.Presumably the workplace population was at high risk of alcohol abuse.Alcohol abusers were significantly worse than general population in self-rated health status(P ＜ 0.01 ),especially in mental health and social health.ConclusionThe incidence of alcohol abuse is relatively high in Xinjiang rcgion,and the problem need more attention.Further survey and early intervention work for highrisk group are advised to achieve the purpose of prevention and control.

Objective To analyze the clinical results and early complications of corpectomy and reconstruction with titanium mesh cage implantation and pedicle screw fixation via a single posterior approach for severe thoracic and lumbar fractures.Methods Forty-four patients treated by reconstruction with titanium mesh cage implantation and pedicle screw fixation via a single posterior were studied retrospectively.There were 35 males and 9 females,with an average age of 37.3 years(range,19-66 years).The injury segments include 1 case at T11,5 cases at T12,20 cases at L1,11 cases at L2,5 cases at L3 and 2 cases at L4.According to AO classification,there were 24 cases of A3,17 cases of B1 and B2,and 3 cases of C1.According to ASIA,there were 10 cases of grade A,17 cases of grade B,10 cases of grade C and 7 cases of grade D.The neurologic function and effectiveness of correction of preoperative,immediate postoperative and 2years follow-up were compared,and the clinical outcome and early complications were analyzed.Results The follow-up time was 24 to 58 months,mean 38.9 months.At the time of 2 years postoperation,43 cases of incomplete neurologic deficit had improved 1 or 2 ASIA grades except 1 case of grade A.The results of decompression and reduction were satisfactory from the postoperative radiographic examinations.The correction maintained well and the implant loosening was not seen in 43 cases(97.7%)at the last follow-up.The com plications include:excessive blood loss(＞1500 ml)in 9 cases,transient nerve root injury in 4,cerebrospinal fluid leakage in 3,instrumentation failure in 1,mesh cage malposition in 3,iatrogenic leaving of free bone granula into the canal in 2,and superficial infection in 1.Conclusion This technique is effective for decompression and fusion,less invasive than combined anteroposterior procedure,and may be another good alternative for the treatment of severe thoracic and lumbar fractures.The early complications are not rare,but most of them are not serious and are relative to techniques.
