ABSTRACT

Objective To approach the surgical timing for the conjoined twins, location of the separation line for the joined liver, and the separation method.Methods The common bile ducts of the conjoined twins were considered as two vertical lines, and a vertical line running parallel to the two lines was set as the separation line for the joined liver.Local blood flow blocking method was then used to separate the joined liver.Results Among all the three cases of the conjoined twins, one case was with sternoxiphopagus and the other two with thoracoabdominalpagus.All the three cases of con-joined twins shared the common livers, but each case had respectively separated gallbladders and bile ducts.They underwent the surgical separation at the age of 28 d and 96 d and 89 d successfully.Their liver sections bled rarely by blocking the local blood flow.The liver function recovered successfully af-ter the operation.All the 6 sick children recovered and were discharged from our hospital.Conclusion Porvided the conjoined twins shared the joined liver with respectively separated common bile ducts, in most cases, the injuries of the important liver vascular as well as bile ducts could be avoided when the separation line for the joined liver was selected with the common bile ducts of the conjoined twins as the longitudinal coordinate.The local blood flow blocking method only blocked the local blood flow, in-terfering to the liver blood flow in the non-operating areas rarely, which was instrumental in the recovery of the liver function and increase of the survival rate of the conjoined twins after the operation.

ABSTRACT

Objective To investigate the mechanism that BC047440 gene regulates nuclear fac-tor κB sigal passway and analyze the differential expression gene between HepG2 cells and HepG2 cells BC047440 gene silenced by RNAi using 35K Human Genome Array. Methods The differential expres-sion gene between HepG2 cells and HepG2 cells with BC047440 gene silenced was analyzed by 35K Human Genome Array, and the data were submitted to the database and MAS system of Capitalbio Corporation.Then TRAF6 was confirmed by RT-PCR test. Results Among the total 35000 probe sets, the expression of 59 genes was down-regulated for more than 50% and 130 genes were up-regulated more than 2 fold in the silencing group when compared with normal controls. TRAF6 mRNA was decreased for 29.5% in silicening HepG2 compared with that of wild HepG2 by RT-PCR, which is similar to human genome array(23.06%).Conclusion The high throughput and effective oligomicroarray can analyze the differential expression gene and BC047440 gene might regulate NF-κB signal pathway inderectly by TRAF6.

ABSTRACT

Objective To investigate whether the proliferation of HepG2 ceils is influenced by interfering BC047440 gene with small hairpin RNA (shRNA) expression plasmid. Methods According to the sequence of BC047440 gene, 2 pairs of BC047440 gene-specific shRNA (shRNA1 and shRNA2) were designed and synthesized. After primer annealing, they were inserted into plasmid pGenesil-1 to construct the shRNA expression plasmids. The recombinant plasmids were transfected into HepG2 cells. The expression of BC047440 gene was detected by quantitative fluorescent PCR, the proliferation of HepG2 cells by MTT assay and the changes of cell cycle by flow cytometry. Results Two shRNA expression plasmids were constructed successfully and were confirmed by restriction enzyme digestion and sequencing. Quantitative fluorescent PCR analysis showed that shRNA1 and shRNA2 could specifically inhibit the expression of BC047440 gene in HepG2 cells, with the inhibition rate of 80.22% and 58.63%, respectively. The shRNA effectively inhibited the proliferation of HepG2 cells, and arrested the cell cycle in S phase. Conclusions The shRNA significantly inhibits the expression of BC047440 gene and the proliferation of HepG2 cells. The expression of BC047440 may be correlated with the proliferation of HepG2 cells.

ABSTRACT

Objective To investigate the feasibility of combined laparoscopic resection of gallbladder and other viscera. Methods The clinical data of 69 cases of combined laparoscopic resection of gallbladder and other viscera from January 1999 to July 2004 were reviewed retrospectively. Results The laparoscopic operation was successful in 69cases,and no case was converted to laparotomy.The average operation time was(85.5?18.6)min,and the time of return of gastrointestinal function was(27.3?6.2)h. The average hospitalization time after operation was(3.9?0.8)d.There were no operative or postoperative complications , and the therapeutic results were satisfactory. Conclusions The combined laparoscopic resection of the gall bladder and other viscera is safe and feasible. It is possible to treat gallbladder diseases and associated lesions of abdominal viscera simultaneously. The lesions of several organs can be treated at one operation. This can significantly decrease patients′ pain and lower the cost of treatment, and is worthy of wide usage.
