Objective To analyze the effect of partial nephrectomy with three-dimensional laparoscopy for the treatment of renal tumor.Methods From October 2013 to September 2015, 11 patients underwent 3D laparoscopic partial nephrectomy for renal tumor in our hospital.All the cases were given retroperitoneal approach.The renal artery was seperated and blocked, and the renal tumor was exposed and completely resected around the edge.The wound was double layer sutured with Vicryl.Results All the 11 operations were finished smoothly without conversion to open surgery.The operative time was 70-180 min (mean, 100 min), the ischemic time was 14-35 min (mean, 25 min), and the estimated blood loss was 50-300 ml (mean, 90 ml).There were 1 case of intraoperative peritoneal perforation, 2 cases of subcutaneous emphysema, and 1 case of perirenal hematoma.No other operative or postoperative complications occurred.The post-operative hospital stay was 5-10 d (mean, 6 d).Post-operative follow-ups for 3-14 months (mean, 10 months) in 10 cases found no recurrence or metastasis or renal dysfunction.Conclusions Partial nephrectomy of renal tumor with three-dimensional laparoscopy is safe and feasible.The outcome is satisfying and worthy of application.

ObjectiveTo observe the risk factors influencing the prognosis of critical ill patients with acute respiratory distress syndrome (ARDS).MethodsThe clinical data of 67 critical ill patients with ARDS from 2003 to 2004 were reviewed retrospectively.ResultsThe acute physiology and chronic health evaluation (APACHEⅡ) scores and age were all differed significantly between survivors and non-survivors groups (P<0.05). The earlier of respiratory supported, the lowest of mortality (P<0.05).Conclusion APACHEⅡ scores, age and the time of starting respiratory support are main risk factors for mortality of critical ill patients with ARDS.

Inefficient degradation of lignocellulose is one of the main barriers for the utilization of renewable plant biomass for biofuel production. The bottleneck of the biorefinery process is the generation of fermentable sugars from complicated biomass polymers. In nature, the main microbes of lignocelluloses deconstruction are fungi. Therefore, elucidating the mechanism of lignocelluloses degradation by fungi is of critical importance for the commercialization of lignocellulosic biofuels. This review focuses on the progress in lignocelluloses degradation pathways in fungi, especially on the advances made by functional genomics studies.

Objective:To explore the safety and efficacy of continuous pair triangular flap plasty in the treatment of webbed penis.Methods:The clinical data of 5 patients with webbed penis treated by continuous pair triangular flap plasty in Tianjin Baodi Hospital from November 2020 to January 2021 were retrospectively analyzed. The average age was 18.2 (15-24) years old. Physical examination showed a webbed fusion between the ventral skin of the penis and the scrotal skin, the penoscrotal angle disappeared and penile erection was limited. The web extended to or exceeded the middle of the penis in the 5 cases. None of the 5 patients had other penile malformations. Taking the ventral midline of the penis and the junction of the penis and scrotum as the origin, a " Z-shaped" incision was made above and below it respectively, and two triangular flaps with the same size and shape but opposite direction were formed respectively. Then the triangular flaps were switched and sutured.Results:The average operation time of five patients was 13(10-20) minutes. The operative average blood loss was 1.6(1-3)ml. All patients had good wound healing and no surgical complications. Three months after operation, the appearance of the penis was satisfactory and erection was unrestricted.Conclusions:Continuous pair triangular flap plasty overcomes the disadvantages of traditional operation, and has the advantages of simple operation, good operation results and few complications. It is a good choice for the treatment of webbed penis.
