Objective To evaluate the techniques and effects of arthroscopic resection of cystic lesions of soft tissue. Methods Twenty-six patients with soft tissue cysts underwent arthroscopic shaving of cyst wall from February 1998 to February 2001. Results Follow-up observation ranged from 6 months to 12 months, with a mean of 8.6 months. The total effective rate reached 96.2% (25 of 26), and no postoperative complications occurred. Recurrence was only seen in 1 patient with thecal cyst on the right dorsal wrist. Conclusions Arthroscopic resection of cystic lesions of soft tissue can be a less invasive method, with fewer complications, a high effective rate and a rapid recovery.

Objectives To explore the effects of hyperosmosis of sea water and low temperature on hemorrhage and coagulation sys- tem of dogs after open abdominal injury followed by sea water immersion,and to observe the efficiency of plasma in addition to routine first aid,so as to provide a theoretical basis for the early treatment of open abdominal wound in naval warfare.Methods 24 dogs with open in- jury of the abdomen were randomly divided to three groups with 8 animals for each group.The dogs in control group were not subjected to sea water immersion and received routine treatments;dogs in conventional therapy group were immersed in sea water and then given the routine first aid;dogs in plasma group were immersed with aqua marina and then given a combined treatment of routine first aid plus an in- fusion of plasma.The following parameters were measured and recorded:survival time,body temperature,mean arterial blood pressure, osmotic pressure of plasma,prothrombin time,partial thromboplastin time,d-dimer and factorⅡ.Results Prothrombin time and partial thromboplastin time were significantly prolonged,D-Dipolymer increased and factorⅡdecreased after sea immersion with open abdominal wound.The survival time of dogs in plasma group(45.6?12.5h)was significantly longer than that of dogs in both control and conven- tional therapy groups(P

BACKGROUND:The blood supply is essential for the repair of the meniscus after the suture of it in the injured knee joint. According to the condition of blood supply, the meniscus was divided into three zones by Arnoczk in 1982. The absolute vascularization zone, in which the distance to the combination part of meniscus and synovial membrane is inferior to 3mm, is called the red zone. The absolute devascularization zone, in which the above-mentioned distance is superior to 5 mm, is called the white zone.And the relative vascularization zone with the distance between 3 mm to 5mm is called red-white zone.OBJECTIVE: To observe and discuss the anatomical features of the blood supplyof the meniscus.DESIGN:Single sample observation.SETTING:Department of Orthopaedics, Huaxi Hospital of Sichuan University.PARTICIPANTS: The study was conducted in Huaxi Hospital of Sichuan University during the period from September 2000 to March 2001.Nineteen cases were collected, including 19 knees (38 menisci) from the subjects, 17 male and 2 female, whose age varied from 21 to 43 years old.All the samples were obtained in the amputation operation, the isolated limbs were without the change of re-transplantation and the voluntary donations from the non-minorities living in Sichuan.meniscus samples: 7 knees (14 menisci) were taken. After the femoral artery intubation and infusion of the heparinized normal saline, the vascular bed had no blood and then was infused with the normal saline and ink of 0.5 volume fraction and the infusion pressure was 13 kPa. The infused meniscus samples underwent the dehydration of gradient ethanol,the transparency of dimethylbenzene, and preservation with ilex pedunculosa, and then the blood supply of the menisci was observed and distribution of the meniscus section: 6 knees (12 menisci) with fresh and uninfused menisci were taken. The sections obtained at the sagittal plane,the coronal plane and the horizontal plane underwent hematoxylin-eosin staining. Then the tissues structure and blood supply of the meniscus samples were observed with light microscope. Another 6 knees (12meniscus) underwent the specific CD34 antibody immunohistochemical staining. Then the tissue structure and blood supply distribution of the meniscus samples were observed with the light microscope.in the devascularization zone of the meniscus.RESULTS: Nineteen cases with 38 menisci all went into the final result resourced from the medial and lateral genicular arteries and the middle genicular artery. The small vessels from them form the peripheral capillary vessel plexus and annular vessel meshwork in the synovium and joint capsule and then go into the menisci for the nutrition of the lateral The apparent lunar artery is sent by the vessel plexus around the meniscus into the body of the meniscus and arranges in the inferior,middle and superior layers and dominates 25%-30% of the zone around The vessels of the angular part of the semilunar plate cover the whole meniscus. The nutrition is supplied by the membranous synovium on the surface of the meniscus.Rich blood supply was observed in the anterior and posterior angular laminated blood supply in the body of the meniscus was newly devascularization zone of the meniscus is supplied from the joint synovial fluid is explicit.

Objective: To set a quantified diagnostic standard for large intestinal cancer of spleen qi deficiency syndrome. Methods: The spleen qi deficiency syndrome was identified by experts on the basis of clinical epidemiological investigation of 311 patients suffering from large intestinal cancer. Corresponding points were assigned to the correlative factors (traditional Chinese medicine symptoms) on the basis of symptom differences between spleen qi deficiency syndrome and non-spleen-qi-deficiency syndrome. The best threshold was determined by receiver operating characteristic curve (ROC) according to syndrome differentiation from expert team, and the quantified diagnostic standard was established. The syndrome identification from the expert team which was regarded as golden standard was tested retrospectively. Results: All the traditional Chinese medicine symptoms possibly related to spleen qi deficiency syndrome were analyzed based on the opinions of experts, and 28 symptoms were confirmed as candidate correlative factors. The occurrence of 11 symptoms between spleen qi deficiency syndrome and non-spleen-qi-deficiency syndrome showed statistical differences by means of crosstabs analysis (P<0.05). The 11 symptoms were filtered by logistic regression analysis, and tiredness, fatigue, loose stool, and poor appetite were finally determined as the symptoms relative to large intestinal cancer. These four symptoms were analyzed with conditional probability conversion and endowed with 16, 11, 4 and 8 points respectively. The diagnostic standard of spleen qi deficiency syndrome of large intestinal cancer was over 13 points. The sensitivity, specificity and accuracy of retrospective examination were all above 80%, and its positive likelihood ratio was 9.89. Conclusion: The quantified diagnostic standard for spleen qi deficiency syndrome of large intestinal cancer is in accordance with clinical characteristics of large intestine cancer and the characteristics of TCM syndrome diagnosis.

Objective The aim of this article is to review and analyze the timing and surgical management of mediate and severe atrioventricular valve regurgitation(AVVR) in single-ventricle patients.Methods Between June 2006 and October 2011,twenty-three cases of single-ventricle patients accompanied with AVVR underwent atrioventricular valve plasty or replacement.There were 17 males and 6 females.Their ages ranged from 2.1 to 22.0 years,and their weight from 12.5 to 59.0 kg.There were 3 cases of A type of single ventricle,17 of B type,2 of C type,and 1 of D type.All cases had one atrioventricular valve except one of D type with 2 groups of atrioventricular valves.There were 18 patients with sever AVVR and 5 with the moderate.Before the management of AVVR,12 patients had undergone the first stage palliation,including B-D Glenn procedure 11 cases and A-P shunt 1 case.The periods between the two stages operations were 7-96 months.Among the all,there were 7 cases of atrioventricular valve replacement ; 3 cases of atrioventricular valve replacement and TCPC ; 5 cases of atrioventricular valve replacement and B-D Glenn procedure ; 2 cases of atrioventricular valve repair and TCPC ; 4 cases of atrioventricula repair and B-D Glenn procedure; 1 case of atrioventricular valve repair,B-D Glenn procedure and TAPVC repair; 1 case of atrioventricular valve repair,B-D Glenn procedure,PA Banding and TAPVC repair.Results In this group,there were 65.2％ patients who underwent atrioventricular valve replacement.The ones with moderate regurgitation underwent atrioventricular valve repair.Only 3 of the 18 cases with severe regurgitation could underwent atrioventricular valve repair(P =0.002).Three cases died.The mortality was 13％.All cases undergone atrioventricular valve repair were alive.The mortality of atrioventricular valve replacement was 20％.All the post-operative alive were followed up.Their follow-up period were between 0.8-6.3 years,withoud a dead case.Conclusion The regurgitation with single ventricle should be managed before the image of myocardium occurred.It is the best time to manage the atrioventricular valve when the regurgitation was moderate.The atrioventricular valve replacement is effective to the cases of single ventricle with severe AVVR.

Objective The aim of this study is to retrospectively analyze surgical management of absent pulmonary valve syndrome(APVS).Methods Between January 2005 and January 2012,totally 11 children with APVS underwent primary surgical correction.There were 7 boys and 4 girls.Age at surgeries range from 1 to 5 years,and wcight from 10.2-17.5 kg,with average (12.3 ± 3.4) kg.Surgical procedures include VSD repair,pulmonary arteries reconstruction and RVOT reconstruction with monocusp valve.5 cases chose Lecompte maneuver as an option to release compression to bronchus,5 cases underwent fibroscopy inspection and airway secretion suction,and 4 cases adapted deep hypothermic circulatory arrest (DHCA)during correction procedures.All survivors are routinely followed-up with echocardiogram.Results All 11 cases survived,2 of them suffered from frequent lungs infections during the first year post surgery.No case exists bronchus or pulmonary arteries compression.Conclusion APVS is a rare congenital heart defect,which may challenge perioperative managements and operations.Ideal surgical correctiou includes RVOT reconstruction,decompression of bilateral bronchus,and airway inspection with fibroscopy.However,compression of intrapulmonary bronchi by abnormally branching pulmonary arteries may expose patients to a relative long time of medication therapy after surgical correction.A large number of patients with long-term follow-up are needed to draw definitive conclusions on this strategy' s effectiveness.

Objective Retrospectively analyze primary experences of surgical correction of complicated aortic arch anomaly with autologous palmonary artery.Methods Between July 2010 and December 2012,13 cases of complicated aortic arch anomaly underwent reconstruction of aortic arch with autologous pulmonary artery.Classifications of aortic arch anomaly were interrupted aortic arch with ventricular septal defect in 4 patients,ventricular septal defect associated with coarctation in nine patients.There were 7 males and 6 females.Their age at surgeries ranged from 1 month to 16 years,and the body weight were from 3.5 kg to 52.0 kg with median weight of 12.6 kg.Cardiopulmonary bapass was estabished with dual arterial cannulations in patients with interrupted aortic arch.During cooling to deep hypothermia(rectal temperature was 18 ℃),intracardiac defects were totally corrected.Arch anomaly was reconstructed under deep hypothermia,including deep hypothermic cardiac arrest(DHCA) in 9 patients,deep hypothermia with regional perfusion in 4 patients.Anterior wall of pulmonary artery was excised in all of 13 patients.In 4 cases,the excised wall of anterior wall of pulmonary artery was sutured to form a conduit with different diameters according to the patient's bady surface area.Two ends of the conduit were anastomosed the aortic arch and desceding aorta respectively.In another 9 patients,aortic arch was augmented with tailored pulmonary artery patch in oval shape.The defect of pulmonary artery was repaired with autologous pericardial patch.Results There was only 1 death due tomutiple organ failure postoperatively.Another 12 patients survived without neurologic complications.Differences of arterial pressures between upper and lower extremeties were not monitored in all cases.During follow-up,routine echocardiogram showed satisfactory results with unobstructive blood flow at the aortic arch.Conclusion Autologous pulmonary artery can be used to relieved complicated aortic arch anomaly completely without any tension of anastomosis site and compression of left main bronchea postoperatively.More patients with long-term follow-up are necessary to draw an accurate conclusion of this technique.

Objective: To investigate the effects of trentment with hydroxythy starch(130/0.4) on the serum albumin and immunologic function in postoperative patients with obstructive jaundice.Methods: 24 patients with obstructive jaundice were randomly divided into the control group(n=12) and hydroxythy starch(130/0.4) (HS) group(n=12). The serum ALB was detected 1d, 3d, 5d, 7d after the operation,and the immunologic index were detected 1d and 7d after the operation.Results: The ALB content of control group and HS group were not significantly different in the postoperative 1d and 7 d(P>0.05) and had significant differences in the postoperative 3 d, 5 d (P<0.05).All immunologic index had no significant differences in the postoperative 1d, 7d (P>0.05).Conclusion: The ALB content of patients with obstructive jaundice may decrease postoperatively. Treatment with hydroxylthy starch(130/0.4) can alleviate the drop of the ALB content. But it has no effects on immunologic function.
