Pancreaticobiliary maljunction(PBM)is closely related to many surgical diseases in which are commonly seen in clinical practice.However,diagnosis of PBM is difficult and it is easily missed.The lack of knowledge and awareness of PMB has once made PBM “the forgotten corner of abdominal surgery”.This essay summarized the current knowledge on the diagnosis of PBM by medical imaging.

Objective To investigate the optimal surgical timing for rib internal fixation.Methods The clinical data of 143 patients with rib fracture were retrospectively analyzed.The patients were divided into early phase fixation group (62 cases) and late phase fixation group (81 cases) according to the time from trauma to internal fixation.The ratio blood lose and body surface area,pulmonary complications and the changes of C reactive protein level before and 5 days after operation were recorded and compared.Results All the patients were healing.The median C reactive protein before operation in late phase fixation group was 45 mg/L,in early phase fixation group was 23 mg/L,there was statistical difference (P ＜ 0.01).The ratio blood lose and body surface area in early phase fixation group was (334.19 ± 37.53) ml/m2,the rate of pulmonary complications was 22.6％(14/61),in late phase fixation group was (438.99 ± 55.24) ml/m2 and 38.3％ (31/81),there were statistical differences (P ＜ 0.01 or ＜ 0.05).The median C reactive protein 5 days after operation in early phase fixation group was 189 mg/L,in late phase fixation group was 258 mg/L,there was statistical difference (P ＜ 0.05).Conclusion Early phase (72 hours) rib internal fixation is expected to reduce patient trauma of systemic reactions,reduce the incidence of bleeding and pulmonary complications.

[Objective]To probe the research and treatment for Hashimoto thyroiditis in Th1/Th2 migration.[Methods]By referring to related literature from both home and abroad,the author tries to analyze and sort the literature and comes to a reasonable conclusion. [Result]There is a lot of experimental re-search on correction of Hashimoto thyroiditis Th1/Th2 migration at home and abroad,but less clinical treatment research.[Conclusion]Th1/Th2 cellmigra-tion is one of the reasons for Hashimoto thyroiditis.It can promote the development of the disease, have something to do with the rise of thyroid autoanti-bodies.

OBJECTIVE: A series of Bobath concept, Bobath theoretical hypothesis and clinical practice were summarized, to proVide a better understanding of Bobath concept involved in nervous tissues repairing and functional reconstruction. METHODS: Articles concerning the Bobath treatment for stroke-related literature were retrieved in Highwire press, MEDLINE, and Google from 2001 to 2009, using the key words of "Bobath concept, stroke physical therapy". Data of each study were extracted and analyzed following retrieval. Inclusion criteria:①Bobath concept and its theoretical hypothesis. ②New development of Bobath concept in clinical practice. Exclusion criteria: Repetitive studies. The results of retrieved literatura were analyzed. RESULTS: The theoretical basis of Bobath concept is based on present-day knowledge of motor control, motor learning, neural and muscle plasticity, and biomechanics. The latest theories and viewpoints are rasourced from International Bobath Instructors Training Association and the British Bobath Tutors Association. They expounded on the Bobath concept from linking participation, activities and underlying impairments, organization of human behavior and motor control, the consequences of injury and dysfunction in the execution of movement, neural and muscle plasticity, motor learning and so. This article also discusses several important questions which meet in clinical practice. CONCLUSION: Bobath therapy, as a traditional method for stroke rehabilitation, is constantly absorbing the research results from current neuroscience, psychology and other disciplines, and blended with other treatments to promote the development of neuro-rehabilitation medicine.

Objective To compare complication,nutritional status and quality of life between total gastrectomy and jejuna interposition after proximal radical gastrectomy in patients with advanced proximal gastric carcinoma.Methods Eighty-five patients with proximal stomach cancer were enrolled from Jan.2002 to Dec.2008,total gastrectomy group(Control group) had 40 cases,jejuna interposition after proximal radical gastrectomy(Experimental group) included 45 cases.Nutritional status,incidence of reflux esophagitis and cholecystolithiasis,5-year survival rate,quality of life were investigated.Results There was no significant difference in 5-year survival rate between two groups(P ＞ 0.05).Incidence of reflux esophagitis in Experimental group was significantly lower than that in Control group(P =0.042).Incidence of cholecystolithiasis in Experimental group was significantly lower than that in Control group (P =0.038).Hemoglobin,albumin,vitamin B12 and ferritin in Experimental group were significantly higher than those in Control group[(142.2 ±8.6) vs (128.4 ±8.4),(41.3 ±5.8) vs (35.9 ±3.8),(271.5 ± 49.7) vs (184.5 ± 24.6),(220.2 ± 59.7) vs (170.2 ± 27.6),P =0.036,0.024,0.032,0.026].Diet and labor in Experimental group were better than those in Control group (P =0.042,0.048).Conclusion Jejuna interposition after proximal radical gastrectomy decrease incidences of reflux esophagitis and cholecystolithiasis,improve nutritional status and quality of life.

Objective To observe the effect of sensory reeducation on the motor function and activities of daily living (ADL) in stroke patients with proprioceptive disturbance. Methods Sixty patients with proprioceptive disturbance after stroke were randomly divided into the treatment group and observation group, and 30 stroke patients with no proprioception disturbance were recruited as the controls. Three groups were treated with routine rehabilitation interventions, but the treatment group were given sensory reeducation in addition to the regular treatment. Fugl-Meyer motor assessment scale (FMA) and sensory assessment scale, and with Barthel index (MBI) for activities of daily living (ADL) were used to evaluate the patients before and after treatment. Results FMA and MBI scores of patients in three groups were increased significantly (P<0.01) after treatment. The scores of patients in observation group were significantly lower than those of the control group and treatment group (P<0.01). Those of the treatment group and the control group were with no significant difference (P>0.05). Conclusion The proprioception disturbance significantly affects the rehabilitation process, and sensory reeducation can improve the sensory function, motor function and activities of daily living (ADL).

Objective To analyze the diagnose and treatment of drug-induced hypersensitivity syndrome (DIHS) in children.MethodsThe clinical data from one case of highly suspected DIHS were retrospectively analyzed. The related literatures were reviewed.ResultsA 22-month-old male child with severe pneumonia, after treated with vancomycin, suffered with high fever and skin rash combined with hepatic lesion and hematological system disorder. After withdrawal of vancomycin and then treatment with the combination of high-dose methylprednisolone and intravenous immunoglobulin, the clinical symptoms were gradually relieved in 24 hours. The child was improved and discharged on 17th day.ConclusionThe child has the characteristics of DIHS which is highly suspected to be caused by vancomycin.

Pediatric blood purification requires reliable access to the circulation.Central venous catheters play an important role in the delivery of pediatric blood purification.A central venous noncuffed,nontunneled catheter is the best choice for short-term(less than 3 weeks) blood purification.A cuffed,tunneled catheter is preferable to long term(more than 3 weeks) blood purification.However,there are many complications associated with central venous catheters,such as catheter-induced thrombosis,catheter-related infection,and central vein stenosis.This article reviews the prevention and treatment of complications most frequently occurring with central venous catheters.
