OBJECTIVE: To analyze the research literatures related to bioartificial liver, and to make a conclusion concerning the development of bio-artificial liver.DATA SOURCES: Using bioartificial liver, liver cell, hepatocyte culture and bioreactor as search terms, searching Ovid, Springer Link database, and China National Knowledge Infrastructure, Vip Information database and Wanfang Date (1990.09-2008.09). Literatures search was limited to English and Chinese languages.DATA SELECTION: Researches regarding liver cells of bioartificial liver, reactors and auxiliary equipment was included, and the studies about immune and animal infection studies of bioartificial liver were excluded.MAIN OUTCOME MEASURES: ①The source, quantity and culturing of bio-artificial liver hepatocytes. ②Bioreactor type, nature and type of films. ③Composition of oxygen and temperature control devices of bioartificial liver.RESULTS: Totally 3898 documents seized initially in the searching by computer, according to inclusion and exclusion criteria, 29 were analyzed. Bioartificial liver was a hybrid device in which can culture hepatocytes in vitro, when the patient's blood flows through the device, material exchange with the cultured hepatocytes through semi-permeable membrane or direct contacting can take place, which can perform the same roles of detoxification, synthesis, biological transformation and other functions as real liver cells, so as to achieve the purpose of support and treatment. Bioartificial liver can also be involved in metabolism of the three major nutritive substances, as well as secretion of hepatocyte growth promo ting substances. So it is an effective alternative to the real liver as the function of detoxification and synthesis, and can fills the essential gap between the transplantation and acute liver failure.CONCLUSION: Although the bioartificial liver research has made significant progress, it still faces the problems such as limited liver cells sources, long-term maintenance of liver cell activity and function, and further optimization of the reactor design.

Objective To discuss the surgical strategy and clinical effects of robotic assisted laparoscopic antegrade inguinal lymphadenectomy for penile cancer.Methods We retrospectively analyzed the clinical data and surgical strategy on the 7 cases,who undergoing robotic assisted laparoscopic antegrade inguinal lymphadenectomy,from August of 2016 to August of 2017.The mean age of 7 patients was (49.7 ± 7.5) years old,ranged from 40 to 62 years old,the mean BMI was (27.97 ± 3.86) kg/m2,ranged from 21.76 to 33.21 kg/m2 . There were 4 cases of T1,2 cases of T2,1 case of T3,1 case of N1,3 cases of N2,3 cases of N3 according to TNM stages.Preoperative preparation was as follows,preoperative cardiopulmonary assessment,inguinal and pelvic CT or MRI,ultrasound of lower extremity venous,bowel preparation.The patients were placed in a supine position,with an indwelling catheter,with the head positioned lower than the hip at an angle of about 15 degrees,legs were spread apart around 45 degrees,and both knees were slightly bent and externally rotated.The da Vinci robotic patient cart was pushed forward between legs of the patient.A blunt separation was carried out between Scarpa's fascia and the surface of the aponeurosis of the obliquus externus abdominis prior,then subcutaneous space was established by a self-made balloon dilatation.Results 7 cases were completed successfully without robot reposition without any conversion.Operative time of each side ranged from 50 to 90 min (70.0 ± 12.5)min.The blood loss of each side was less than 10 ml.In the 7 cases,the number of nodes removed from left inguinal region ranged from 7 to 18 (14.0 ±3.3).The number of nodes removed from right ranged from 5 to 21 (11.0 ± 3.3).Pelvic lymphadenectomy was completed in the meantime by original trocar site on 4 cases.Till now,no perioperative complications,such as flap necrosis,delayed healing of incision,cellulitis,occurred in inguinal region,except lymphorrhagia in 3 cases.During a follow-up within 3-14 months,there was no recurrence or metastasis in 6 cases except one died from tumor progression with systemic metastasis.Conclusions Antegrade inguinal lymphadenectomy for penile cancer by using Da Vinci robotic surgical system is safe and effective.This technique also appears to diminish the wound related complications associate with the standard open approach.Compared with the similar surgery,we conducted bilateral inguinal lymphadenectomy without patient cart reposition,which simplify the procedure and reduce the using of trocar.According to individual clinical conditions,pelvic lymphadenectomy also can be completed in the meantime by original trocar.
