Comparison of post-operative short-term and long-term outcomes between occult and frank biliary rupture of hydatid disease.

BACKGROUND/AIMS: Intrabiliary rupture (IBR) is the most common and serious complication of hepatic hydatid cyst (HHC). The aim of this retrospective study was to evaluate postoperative short-term and long-term outcome of patients treated surgically for complicated liver hydatid cysts. METHODOLOGY: A total of 168 cases with biliary communication of hydatid cyst were analyzed retrospectively, 92 of which had biliary communication with an occult rupture while 76 (45.23%) had Frank biliary rupture. Preoperative demography, ultrasonic cyst features, postoperative short-term complications, postoperative follow-up (long-term) complications and hospital stay were recorded and analyzed. RESULTS: There were no differences in the demographic characteristics and preoperative cyst features in Frank and occult group. Compared with the Frank group 9.34 +/- 1.25 (days), the postoperative stay in occult 6.97 +/- 1.62 (days) were relatively shorter. The incidence of overall postoperative short-term complications and long-term complications were insignificantly lower in occult group (22.82%) than Frank group (30.26%) with P = 0.275. Incidence of postoperative biliary leakage 8 (8.69%) and abscess 5 (5.43%) in occult group was insignificantly more common than Frank rupture with biliary leakage 5 (6.5%) and abscess 2 (2.63%) with P value was 0.609 and 0.365 respectively while long-term biliary stricture is significantly greater in Frank group (10.52%) then occult group (0%) with P = 0.01. CONCLUSIONS: Frequency of occurrence of postoperative short-term complications biliary fistula and abscess is relatively more common in occult rupture with transcystic drain due to its indolent course, inability to find and suture the rupture orifice, and incomplete decompression while biliary stricture is significantly more common in Frank group due to its involvement of major bile ducts.

Mitofusin2 Promotes ß Cell Maturation from Mouse Embryonic Stem Cells via Sirt3/Idh2 Activation.

ß cell dysfunction is the leading cause of diabetes. Adult ß cells have matured glucose-stimulated insulin secretion (GSIS), whereas fetal and neonatal ß cells are insensitive to glucose and are functionally immature. However, how ß cells mature and acquire robust GSIS is not fully understood. Here, we explored the potential regulatory proteins of ß cell maturation process and the capacity for GSIS. Combined with the data from public databases, we found that the gene expression of Mitofusin2 (Mfn2) showed an increasing trend from mouse neonatal ß cells to mature ß cells. Moreover, its protein expression increased during mouse embryonic pancreas development and ß cell differentiation from mouse embryonic stem cells. Knocking down Mfn2 reduced Urocortin3 (Ucn3) expression, GSIS, and ATP production in induced ß cells, while overexpressing it had the opposite effect. However, neither Mfn2 knockdown nor overexpression affected the differentiation rate of insulin-positive cells. In immature and mature ß cells, Mfn2 and its correlated genes were enriched in tricarboxylic acid (TCA) cycle-related pathways. The expressions of Sirtuin 3 (Sirt3) and isocitrate dehydrogenase 2 (NADP+) and mitochondrial (Idh2) were Mfn2-regulated during ß cell differentiation. Inhibiting Idh2 or Sirt3 reduced cellular ATP content and insulin secretion levels that increased by Mfn2 overexpression. Thus, Mfn2 modulated the induced ß cell GSIS by influencing the TCA cycle through Sirt3/Idh2 activation. We demonstrated that Mfn2 promoted embryonic stem cell-derived ß cell maturation via the Sirt3/Idh2 pathway, providing new insights into ß cell development. Our data contribute to understanding diabetes pathogenesis and offer potential new targets for ß cell regeneration therapies.

3D printing hydrogel with graphene oxide is functional in cartilage protection by influencing the signal pathway of Rank/Rankl/OPG.

3Dprinting is defined as the use of printing technology to deposit living cells, and biomaterials on a given /a substrate. Graphene oxide nanoparticles (GO-np) have been used as a delivery vehicle for small molecule drugs in order to investigate the state of GO-np within 3D tissue constructs in terms of a composite 3D printing scaffold, which in turn is relevant to the protection of cartilage. We transplanted rats with hydrogel/GO-np and hydrogel, which in turn showed that hydrogel/GO-np protected the tissue of cartilage by the signal pathway of Rank/Rankl/OPG. Those findings indicated that GO-np may be potentially used to control the release of carrier materials and influence the signal pathway of Rank/Rankl/OPG.
