RESUMO
Objective:To investigate the effect of single nucleotide variation of osteoprotegerin (OPG) gene on the occurrence of osteoporosis (OP) in patients with gestational diabetes mellitus (GDM) .Methods:From Apr. 2018 to Apr. 2022, 276 pregnant women with GDM who underwent prenatal examination and gave birth in Linyi People’s Hospital were collected for analysis, general data were collected and bone mineral density was tested. According to the bone mineral density test results, they were divided into normal group and OP group. The OPG genotype was tested, and the general information, OPG genotype and allele frequency of the two groups were compared. The differences in bone mineral density among different genotypes of OPG were compared, and the genotypes affecting the risk of OP in GDM patients were analyzed.Results:There was no significant difference in the general data of the two groups of patients (all P>0.05). The allelic distribution of the rs3134069 and rs2073618 loci of the OPG gene in the two groups of patients conformed to the Hardy-Weinberg equilibrium law (all P>0.05). There was a statistically significant difference in the frequency of the AC genotype at rs3134069 between the two groups ( χ2=7.75, P=0.005). Taking patients with the AA genotype as a reference, patients with the AC genotype had a lower risk of developing OP ( OR=0.15, 95% CI: 0.03-0.59). There was a statistically significant difference in the frequency of CC genotype at rs2073618 between the two groups ( χ2=11.30, P=0.001). Taking patients with GG genotype as a reference, patients with CC genotype had a higher risk of developing OP ( OR=7.42, 95% CI: 2.19-27.18). Comparing rs3134069 and rs2073618 loci, there was no significant difference in bone mineral density at each part of the three genotypes (all P>0.05). The multivariate Logistic regression model showed that the AC genotype of rs3134069 ( OR=0.18, 95% CI: 0.03-0.70, P=0.029) was a protective factor for the induction of OP, while GC genotype of rs2073618 ( OR=6.86, 95% CI: 1.57-27.15, P=0.007) were the risk factors for OP in GDM patients. Conclusion:The CC genotype of rs2073618 is significantly positively correlated with the susceptibility to OP in GDM patients.
RESUMO
Objective:To report a pediatric organ donor with brain death due to wild mushroom poisoning to examine whether or not brain death caused by mushroom poisoning might become a potential organ donor and how to evaluate donated organs.Methods:Strict clinical observations, laboratory tests and biopsy were performed for potential donor.Results:This donor's clinical changes were consistent with toxic hepatitis. Gross morphology, laboratory examinations and pathological biopsy of two kidneys were generally normal during organ acquisition. Two kidneys were assigned to two adult recipients and liver was discarded. After a follow-up period of 6 months, one recipient recovered well while another gradually recovered after delayed graft function.Conclusions:This extraordinary case provides some references for selecting potential donors of mushroom poisoning. When the donor's relevant laboratory tests are normal, there is no pathological contraindication, sufficient time is available for estimating the type of mushroom poisoning, observing the trends of organ damage and waiting for the toxin clearance, donor with brain death from wild mushroom poisoning may donate organ.

RESUMO
DCD WeChat ethical review had its necessity and superiority but problems and confusion as well. For instance, WeChat review time was urgent and limited;WeChat review discussed insufficiently even hard to car-ry out;the methods of WeChat review were limited;the authenticity of audit opinion was difficult to grasp;the re-view data privacy existed hidden danger;the review quality was difficult to guarantee;WeChat conference content file archive was difficult, and so on. As to this, the author put forward the following countermeasures:giving war-ranty on the ethical review time as far as possible;initiating the committee review by the referee and uploading the review information to WeChat group, then ethical reviewers expressing their opinions in real names to ensure data confidentiality and privacy protection; strengthening the ethics committee education for organ transplantation; im-proving the quality of the review committee members and moral cultivation;archiving the WeChat conference infor-mation.
RESUMO
Objective To explore the indication and feasibility of laparoscopic hepatectomy. Methods Clinical data of 6 patients undergoing laparoscopic hepatectomy(LH) were collected and retrospectively anallyzed,5 of them with lesions located in surface or edge of Ⅱ -Ⅵ segment,one of them with lesion in Ⅷ segment. These lesions were 5 - 9.6 cm, the average diameter was (6.64 ± 2.60) cm. There were 4 cases of liver cavernous hemangioma, and 2 case of hepatic focal nodular hyperplasia. The liver functions of 6 cases w ere in Child Pugh A . Results All 6 patients were applied laparoscopic hepatetomy successfully, 5 cases were performed partial resection, 1 case underwent laparoscopic hepatic left lateral lobectomy. The average operation time was( 105.17 ± 27.97 )minutes, and the intraoperative average hemorrhage was (247. 50 ± 90.91 ) mL. All of the lesions were completely removed. There were no postoperative complications such as bile leakage or hemorrhage. All patients recovered well. The average postoperative hospitalization was (4.16 ± 1.60)days: Conclusions Laparoscopic hepatectomy is safe and feasible for lesion located in the edge or sur face of liver and left liver.
RESUMO
Objective To study the mechanism of immune hyporesponsiveness of allograft rejection induced by transfusion nonpufsed allopeptide syngeneic immature dendritic cell(imDC) generated from recipient bone marrow progenitors and to explore a possible strategy for liver allograft protection in clinic.Methods Forty experimental rats were randomly divided into 4 group: control group,cyclosporine A(CsA) group,mature DC(mDC) group and imDC group.In control group,Wistar rats only received liver transplantation.In CsA group,Wistar rats underwent liver transplantation plus CsA treatment(10 mg/(kg?d)).In mDC group,recipient-derived mDC 1?106 were infused intravenously through the penile vein to Wistar rats.In imDC group,ImDC with the dose of 1?106 were injected into Wistar rats via the dorsum vein of penile.In each group,five recipients were killed on the 10th day after transplantation,the other five recipients were left to observe survival time.The levels of ALT,AST,TBIL,IL-2,IFN-?,IL-4 and IL-10 were detected.The acute rejection and the expression of FasL/Fas in the grafts were detected by HE and immunohistochemical staining.Western blot was used to detect Scurfin protein expression of CD4+ CD25+ T cells.Results The median survival time of the liver allografts in CsA group and imDC group were significantly longer than that in control group and mDC group(P

Objective To evaluate the feasibility and curative effect of extracorporeal liver perfusion (ECLP) in treatment of acute liver failure (ALF) in pigs. Methods The experiments were carried out in healthy pigs (weight 20-30 kg) under general anesthesia. All of the pigs were randomly divided into 3 groups. ALF model was established by liver blood supply obstructing and portal-systemic shunting. ALF group (n=5): ALF pigs were killed 8 h after establishing. ALF+ECLP group (n=5): ALF pigs were perfused with ECLP for 4 h and killed 8 h after establishing. Normal liver+ECLP group (n=4): normal pigs were dealt with just as ALF+ECLP group. The data of PT, AST, TNF, blood ammonia were collected in all groups. Pathologic changes in liver and brain were detected. Results The levels of PT, AST, TNF, blood ammonia, RBC and HCT in the ALF+ECLP group were lower than those in the ALF group (P
RESUMO
The fragment of MDR1 gene obtained from the plasmid pHaMDR1-1 carrying the whole human MDR1 cDNA, was cloned reversely into the shuttle plasmid pAdTrack-CMV. With the resultant plasmid and the backbone plasmid pAdEasy-1, the homologous recombination took place in the Escherichia coli BJ5183 and the recombinant adenoviral plasmid was generated. The adenoviruses were packaged in the 293 cells. The recombinant adenovirus MDR1 vector would introduce the antisense MDR1 gene into the human multidrug resistance hepatocellular cell line effectively, which would provide an experimental basis for studies on the multidrug resistance in human hepatocellular carcinoma.
