The saponins in different parts of Gynostemma pentaphyllum were analyzed via UPLC-Q-TOF-MS~E. A total of 46 saponins were identified, and the underground part had 26 saponins more than the aboveground part, most of which were trisaccharide saponins. The rat model of hyperlipidemia was established with high-fat diet. This study explored the lipid-lowering activity of total saponins in the underground part of G. pentaphyllum, so as to provide a theoretical basis for the comprehensive utilization of the underground part of G. pentaphyllum. A total of 99 healthy SD rats were randomly assigned into a blank group, a model group, a positive drug group, an aboveground total saponins group, and low-, medium-, and high-dose underground total saponins groups. Except the blank group, the other groups were fed with high-fat diet for 6 weeks. Then, the blood was collected from the orbital cavity to determine whether the modeling was successful according to the serum levels of total cholesterol(TC) and triglyceride(TG). After intragastric administration of the corresponding agents for 30 continuous days, the physical state of the rats were observed, and the body weight and liver specific gravity were measured. Furthermore, the levels of TC, TG, low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), alanine transaminase(ALT), aspartate transaminase(AST), bilirubin, and total bile acids in serum, as well as the levels of superoxide dismutase(SOD), malondialdehyde(MDA), peroxidase proliferator-activated receptor(PPAR-γ) in the liver tissue, were determined. The pathological changes of liver was observed via HE staining. The results showed that the aboveground total saponins and medium-and high-dose underground total saponins can treat hepatocyte steatosis, lower TC, TG, LDL-C, ALT, AST, total bilirubin, MDA, and PPAR-γ levels, and increase HDL-C and SOD levels in the model rats. The effect tended to be more obvious with the increase in dosage. Therefore, the total saponins in the underground part of G. pentaphyllum have good pharmacological effect of reducing blood lipid, which provides a theoretical basis for the comprehensive utilization of the underground part of G. pentaphyllum.

OBJECTIVE: To compare the therapeutic effect of different animal bile powders on lipid metabolism disorders induced by high-fat diet in rats, and analyze the bioactive components of each animal bile powder. METHODS: Sixty Sprague-Dawley rats were randomly divided into 6 groups (n=10): normal diet control group, high-fat diet model group, high-fat diet groups orally treated with bear, pig, cow and chicken bile powders, respectively. Serum biochemical markers from the abdominal aorta in each group were analyzed. Changes in the body weight and liver weight were recorded. Pathohistological changes in the livers were examined. High performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry was used to determine the composition of bioactive components in each animal bile powder. RESULTS: Treatment with different types of animal bile powders had different inhibitory effects on high-fat diet-induced increase of body weight and/or liver weight in rats, most notably in bear and pig bile powders (P<0.05). High-fat diet induced lipid metabolism disorder in rats, which could be reversed by treatment with all kinds of bile powders. Bear bile and chicken bile showed the most potent therapeutic effect against lipid metabolism disorder. Cow and bear bile effectively alleviated high-fat diet induced liver enlargement and discoloration, hepatocyte swelling, infiltration of inflammatory cells and formation of lipid vacuoles. Bioactive component analysis revealed that there were significant differences in the relative content of taurocholic acid, taurodeoxycholic acid and ursodeoxycholic acid among different types of animal bile. Interestingly, a unique component with molecular weight of 496.2738 Da, whose function has not yet been reported, was identified only in bear bile powder. CONCLUSIONS Different animal bile powders had varying therapeutic effect against lipid metabolism disorders induced by high-fat diet, and bear bile powder demonstrated the most effective benefits. Bioactive compositions were different in different types of animal bile with a novel compound identified only in bear bile powder.

Due to its ultra-high sensitivity, specificity and throughput, liquid chromatography tandem mass spectrometry (LC-MS/MS) has become an important analytical tool in clinical laboratories in quantifying various small molecules, such as vitamins, bile acids, steroids and other internal metabolites relevant to maternal diseases. As an effective means of screening and diagnosing diseases in preventive medicine, LC-MS/MS has been widely used in maternal and child health, contributing to the reduction of the incidence of maternal and child diseases and premature morbidity and mortality. At present, LC-MS/MS is an emerging and powerful platform in laboratory testing in China, facing both challenges and opportunities. In this article, the representative applications in the field of maternal and child health are summarized and discussed, along with the major hurdles of LC-MS/MS in clinical recognition and implementation.

The pig bile powder, bovine bile powder, snake bile, sheep bile, goose bile powder, and bear bile powder were contained by the Chinese Pharmacopoeia. The bile power medicine has a long history in traditional Chinese medicine and definite effect. However, the medicine of bile powder(bile) are similar in morphology. Besides, many medicine lack specific microscopic identification characteristics and chemical characteristics. There is a risk of adulteration, especially when the fake medicine were mixed in authentic medicine, it is difficult to detection. The key to control the quality and ensures the clinical efficacy is the good or bad, true or false of the bile power medicine. The STR typing technology is a method that according to differential typing of PCR amplified lengths to compare and identify individual organisms. Based on the principle of STR typing, the easily, rapid DNA fingerprinting method to identify the bile power and adulteration was established.The original animal or bile powder of pigs, cattle, sheep, chickens, ducks, geese, snakes, bears, fish were collected, the 12 S-L1091/12 S-H1478 and 16 S-L3428/16 S-H3667 was obtained by sifted, the DNA fingerprinting of the bile power and adulteration was obtained by STR typing. Every species has different STR fingerprints, so different species can be identified. Besides, the fingerprints have both the authentic and fake's information, the adulteration of authentic and fake can be identified. Therefore, the method to identify the bile power and adulteration was achieved through the combination of two primers. The DNA fingerprinting method established in this study can also be used for other animal medicine.

BACKGROUND/AIMS: Periampullary diverticulum (PAD) is frequently encountered during endoscopic retrograde cholangiopancreatography (ERCP) and has been associated with stone formation in the bile duct. The effects of PAD on the ERCP procedure have been often debated. We aimed to compare the therapeutic success of ERCP between patients with PAD and matched controls. METHODS: We reviewed all ERCPs with findings of PAD in a national database (n=1,089) and compared them with age- and gendermatched controls in a 1:3 fashion (n=3,267). Demographics, endoscopic findings, visualization of main structures, and therapeutic success rates were compared between groups. Secondary analysis compared PAD cases and controls who had gallstone disease. RESULTS: The average cohort age was 68.4±14.3 years and 55.1% were male. ERCP success was similar in both groups, and no significant inter-group differences were found in the multivariate analysis. The presence of PAD did not affect the rates of sphincterotomy or visualization of main biliary structures. Secondary analysis showed similar success rates for gallstone removal between patients with PAD and controls. CONCLUSIONS: PAD may not be considered a hinderance to ERCP success. Further research is needed to determine the best approach to cannulate the ampulla and provide endoscopic therapy for different subtypes of PAD.

Monitoring cerebral oxygenation using a near infrared spectroscopy (NIRS) device is useful for estimating cerebral hypoperfusion and is available during liver transplantation (LT). However, high serum bilirubin concentration can interfere with NIRS because bilirubin absorbs near infrared light. We report a patient who underwent LT with a diagnosis of vanishing bile duct syndrome, whose regional cerebral oxygen saturation (rSO₂) remained below 15% even with alert mental status and SpO2₂ value of 99%. The rSO₂ values were almost fixed at the lowest measurable level throughout the intra- and postoperative period. We report a case of erroneously low rSO₂ values during the perioperative period in a liver transplant recipient which might be attributable to skin pigmentation rather than higher serum bilirubin concentration.

PURPOSE: T category of the eighth edition of the American Joint Committee on Cancer (AJCC) staging system for distal bile duct carcinoma (DBDC) was changed to include tumor invasion depth measurement, while the N category adopted a 3-tier classification system based on the number of metastatic nodes. MATERIALS AND METHODS: To validate cancer staging, a total of 200 surgically resected DBDCs were staged and compared according to the seventh and eighth editions. RESULTS: T categories included T1 (n=37, 18.5%), T2 (n=114, 57.0%), and T3 (n=49, 24.5%). N categories included N0 (n=133, 66.5%), N1 (n=50, 25.0%), and N2 (n=17, 8.5%). Stage groupings included I (n=33, 16.5%), II (n=150, 75.0%), and III (n=17, 8.5%). The overall 5-year survival rates (5-YSRs) of T1, T2, and T3 were 59.3%, 42.4%, and 12.2%, respectively. T category could discriminate patient survival by both pairwise (T1 and T2, p=0.011; T2 and T3, p < 0.001) and overall (p < 0.001) comparisons. The overall 5-YSRs of N0, N1, and N2 were 47.3%, 17.0%, and 14.7%, respectively. N category could partly discriminate patient survival by both pairwise (N0 and N1, p < 0.001; N1 and N2, p=0.579) and overall (p < 0.001) comparisons. The overall 5-YSRs of stages I, II, and III were 59.0%, 35.4%, and 14.7%, respectively. Stages could distinguish patient survival by both pairwise (I and II, p=0.002; II and III, p=0.015) and overall (p < 0.001) comparisons. On multivariate analyses, T and N categories (p=0.014 and p=0.029) and pancreatic invasion (p=0.006) remained significant prognostic factors. CONCLUSION: The T andNcategories of the eighth edition AJCC staging system for DBDC accurately predict patient prognosis.

Robotic single-site cholecystectomy (RSSC) has emerged as an alternative procedure to overcome the shortcomings of single-fulcrum laparoscopic cholecystectomy in terms of the ergonomics and reducing the physical and mental stress of the surgeon. It is also necessary to assess the safety of RSSC for obese patients in a world with an increasing population of obese people. RSSC took a longer operation time, but the actual dissection time was similar to that of single-fulcrum laparoscopic cholecystectomy. There was no difference in postoperative pain, except for during the immediate postoperative period, and in the length of the hospital stay. RSSC had the advantage of reducing the incidence of intraoperative iatrogenic gallbladder perforation. It is critical to prevent any intraoperative bile leakage, which is associated as a worse prognostic factor in those patients with gallbladder cancer. Additional studies with a prospective design and larger number of study subjects will be required to confirm the safety and feasibility of RSSC. Moreover, the cost benefit and safety for treating malignant lesions are also issues to be addressed. RSSC is expected to be further expanded as an operative mode in the future.

BACKGROUND: Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of autosomal recessive liver diseases that present as neonatal cholestasis. Little is known of this disease in Korea. METHODS: The records of five patients histologically diagnosed with PFIC, one with PFIC1 and four with PFIC2, by liver biopsy or transplant were reviewed, and ATP8B1 and ABCB11 mutation status was analyzed by direct DNA sequencing. Clinicopathological characteristics were correlated with genetic mutations. RESULTS: The first symptom in all patients was jaundice. Histologically, lobular cholestasis with bile plugs was the main finding in all patients, whereas diffuse or periportal cholestasis was identified only in patients with PFIC2. Giant cells and ballooning of hepatocytes were observed in three and three patients with PFIC2, respectively, but not in the patient with PFIC1. Immunostaining showed total loss of bile salt export pump in two patients with PFIC2 and focal loss in two. Lobular and portal based fibrosis were more advanced in PFIC2 than in PFIC1. ATP8B1 and ABCB11 mutations were identified in one PFIC1 and two PFIC2 patients, respectively. One PFIC1 and three PFIC2 patients underwent liver transplantation (LT). At age 7 months, one PFIC2 patient was diagnosed with concurrent hepatocellular carcinoma and infantile hemangioma in an explanted liver. The patient with PFIC1 developed steatohepatitis after LT. One patient showed recurrence of PFIC2 after 10 years and underwent LT. CONCLUSIONS: PFIC is not rare in patients with neonatal cholestasis of unknown origin. Proper clinicopathologic correlation and genetic testing can enable early detection and management.
