Objective To analyse the cause of misdiagnosis of tuberculosis peritonitis and discuss feasibility for diagnosis of tuberculosis peritonitis by laparoscopy. Methods 12 patients misdiagnosed as tuberculosis peritonitis were retrospectively analysed. Results Tuberculosis peritonitis wrongly diagnosed because of atypical clinical behaviors in spite of specific laboratory examination. However, laparoscopy could diagnose tuberculosis peritonitis exactly and quickly. Conclusion Laparoscopy is an effective method of diagnosis for tuberculosis peritonitis.

Objective To analyze the imaging manifestation and feature of congenial pulmonary arteriovenous fistulas (CPAVF) and observe the effect of endovascular treatment. Methods The plain films, CT and DSA of CPAVF retrospective- ly were analyzed. The effect of transcatheter embolization with coil was observed by follow-up. Results Feeding artery was pulmonary artery branches in five cases and was branchial artery in one case. The images of all cases were divided into three types: simple type-3 cases, complex type-2 cases and diffuse type-1 case. Both CT and DSA could give the correct diagnosis, however 3 cases were diagnosed wrongly by X-ray. Three cases were underwent transcatheter endovascular em- bolism with coils, and one case were done three times. Systemic arterial oxygen saturation improved strikingly in two pa- tients after treatment, and the symptoms of hemoptsis disappeared immediately after branchial arterial embolism in other case. Conclusion DSA was the best means in the diagnosis of PAVF. CT and three-dimensional reconstruction can be giv- en correct and direct diagnosis for big PAVF, but can not replace DSA in the diagnosis of small PAVF. Percutaneous tran- scatheter endovascular embolism with coils is an effective and safe treatment for PAVF, but it is only a palliative therapy for diffuse PAVF.

Objective To study hepatic blood flow exclusion for the resection of liver tumors involving hepatic hilar region. Methods The clinical data of 16 cases of liver tumors involving hepatic hilar region from January 2005 to March 2008 were retrospectively analyzed. Liver tumors were resected by the technique combining hepatic portal control ( Pringle's maneuver) and normothermie total hepatic vascular exclusion (NHVE). The relation of liver tumors to major vessels, episodes and durations of hepatic blood flow exclusion, intraoperative blood loss and blood transfusion, postoperative complications were analyzed. Results The technique combining Pringle's maneuver and NHVE was used in 16 cases. The mean episodes and durations of Pringle's maneuver were (3.8±1.6) min and (46.6±28.8) min, respectively. The mean episodes and durations of NHVE were (1.6±0.4) min and (23.5±8.2) min, respectively. The mean amount of intraoperativ blood loss was (1250±320) ml, blood transfusion (860±245) ml. Major hepatic vessel injuried were repaired intraoperatively including inferior vena cave in 4 cases, main hepatic veins in 2 cases and portal veins in 2 cases. The serum alanine transaminase(ALT) and bilirubin raised in different degrees after operation, and recovered gradually to normal level. There was no postoperative mortality and serious postoperative complications. Conclusions Alternative use of hepatic blood flow exclusion combining Pringle maneuver and NHVE reduces the time of total hepatic vascular exclusion, improves safety for resection of liver tumors involving hepatic hilar region.

In order to analyze the genotype of RhD-negative blood donors with immune antibodies in Harbin, the voluntary blood donors from 1 April 2008 to 30 september 2011 were detected serologically to determine the RhD-negative donors. The blood donors confirmed to be RhD negative were detected to screen the immune antibodies, the samples with immune antibodies were analyzed by PCR-SSP and DNA sequencing to detect RhD genotype. The results showed that the 12 cases of the immune antibodies (0.95%) were screened out from 1265 cases of RhD-negative donors, among which 9 cases showed anti-D-antibody, 3 cases showed anti-(D+C) antibody; 10 cases were RhD-negative, 2 cases were RHD 711D(el)C. It is concluded that RhD negative and RHD 711D(el)C are easy to be immunized to produce the immune antibodies; RhD-negative population, especially women should be highly aware of avoiding mis-transfusion of RhD-positive blood, and also avoiding multiple pregnancies resulting in newborn's hemolytic disease.

BACKGROUNDNitric oxide (NO) is an important mediator in the pathophysiology of many vascular diseases. However, the definite role of NO in human abdominal aortic aneurysm (AAA) formation is unclear. The aim of this study was to investigate production of NO and expression of inducible nitric oxide synthase (iNOS), and their possible role in AAA.

METHODSA total of 28 patients with AAA, 10 healthy controls, and 8 patients with arterial occlusive disease were enrolled into this study. Standard colorimetric assay was used to examine NO concentration in plasma from patients with AAA and normal controls, and in cultured smooth muscle cells (SMCs). Expression of iNOS in aortas and cultured SMCs were detected by immunochemistry. The correlation of iNOS expression with age of the patient, size of aneurysm, and degree of inflammation was also investigated by Cochran-Mantel-Haenszel chi2 test and Kendall' Tau correlation.

RESULTSExpression of iNOS increased significantly in the wall of aneurism in the patients with AAA compared to the healthy controls (P < 0.05) and the patients with occlusive arteries (P < 0.05). iNOS protein and media NOx (nitrite + nitrate) also increased in cultured SMCs from human AAA (n = 4, P < 0.05), while plasma NOx decreased in patients with AAA (n = 25) compared to the healthy controls (n = 20). There was a positive correlation between iNOS protein and degree of inflammation in aneurismal wall (Kendall coefficient = 0.5032, P = 0.0029).

CONCLUSIONSSMCs and inflammatory cells were main cellular sources of increased iNOS in AAA, and NO may play a part in pathogenesis in AAA through inflammation.

OBJECTIVETo investigate the role of xenogenic (porcine) ADM as dermal substitute in scar treatment.

METHODSAfter scar excision, the wounds were covered with composite grafts of DR procine ADM and autologous thin split-thickness grafts in one stage or in two stages.

RESULTS22 out of 47 cases were treated in two-staged procedure. After the ADMs were applied to the wound, the autologous thin split-thickness grafts were implanted 7 days later. 25 cases were treated in one-staged procedure. The survival rates of composite grafts were (88.3 +/- 3.7)% for subcutaneous recipient bed and (89.7 +/- 3.4)% for deep fascia recipient bed in group with two-staged procedure, compared with (92.5 +/- 4.1)% and (93.2 +/- 5.2)%, respectively, in group with one-staged procedure. Early after grafts taken, the grafts had a pink colour and smooth surface. The patients were followed up for 90 days at most. The survived composite grafts were durable, elastic, smooth and soft with good function and appearance like normal skin. They could even be pinched up. The scar along the edge of the grafts was slightly hypertrophic.

CONCLUSIONSThe survival rate of composite graft is higher in patients with one-staged procedure. The elasticity and textural of the taken grafts are better on subcutaneous recipient bed than on deep fascia recipient bed, though the function has no difference. Xenogenic (porcine) ADM can be an optimal dermal substitute for wound coverage after scar excision.
