BACKGROUND AND OBJECTIVES
Hepatobiliarypancreatic tuberculosis (HBPTB) is a less common form of tuberculosis that often presents as malignancy or lithiasis. Advances in diagnostics and minimally invasive procedures have led to the detection of more patients with milder forms of TB requiring surgical management. Due to the low incidence rates and lack of standardized approaches, additional studies are needed to improve patient outcomes. This study examined the risk factors, diagnostic methods, and treatments for HBPTB patients at the University of the Philippines – Philippine General Hospital (UP-PGH) from January 1, 2014 to December 31, 2021.
METHODSThis retrospective descriptive study utilized our institutional database to identify patients who underwent a surgical procedure for HBPTB and their associated risk factors. Inclusion criteria required biopsy or microbiologic proof of tuberculous involvement of the biliary tract or nearby structures.
RESULTSAmong a total of 45 patients, the most common admitting diagnosis were HBP tuberculosis (37.8%) and malignancy (35.6%). 47.6% of patients had a previous or concurrent TB exposure. Sixty percent had subclinical malnutrition indicated by normal weight and low albumin. The liver (37.8%) and the bile ducts (33.3%) were the most common organs involved. The most common surgical procedures done were ultrasound-guided liver biopsy, biliary enteric anastomosis, percutaneous transhepatic biliary drainage (PTBD), and endoscopic retrograde cholangiopancreatography with or without stenting (ERCP).
CONCLUSIONSThis study provides additional data for clinicians to tailor diagnostic and treatment plans accordingly. Striking a balance between surgical procedures and appropriate anti-tuberculous therapy (ATT) is essential for successful treatment. Local data can be useful to help identify tuberculosis patterns unique to Filipinos and highlight socio-economic factors contributing to this rare presentation of TB.

As a member of the apolipoprotein C (ApoC) family with a relatively high content, ApoC3 plays a major role in the regulation of triglyceride metabolism, and plays an important role in the occurrence and development of cardiovascular diseases, glucose and lipid metabolism disorders. Nonalcoholic fatty liver disease (NAFLD) refers to the accumulation of a large amount of fat in the liver in the absence of a history of chronic alcohol consumption or other damage to the liver. A large number of previous studies have shown that there is a correlation between the gene polymorphism and high expression of ApoC3 and NAFLD. In the context of hypertriglyceridemia (HTG), this article reviews the relationship between ApoC3 and NAFLD, glucose and lipid metabolism, and islet β cell function, showing that ApoC3 can not only inhibit lipoprotein lipase (LPL) and hepatic lipase (HL) activity, delay the decomposition of triglyceride in plasma to maintain the body's energy metabolism during fasting, but also be significantly increased under insulin resistance, prompting the liver to secrete a large amount of very low-density lipoprotein (VLDL) to induce HTG. Therefore, targeting and inhibiting ApoC3 might become a new approach to treat HTG. Increasing evidence suggests that ApoC3 does not appear to be an independent "contributor" to NAFLD. Similarly, our previous studies have shown that ApoC3 is not an independent factor triggering islet β cell dysfunction in ApoC3 transgenic mice, but in a state of excess nutrition, HTG triggered by ApoC3 high expression may exacerbate the effects of hyperglycemia and insulin resistance on islet β cell function, and the underlying mechanism remains to be further discussed.

Objective: To analyze the clinical characteristics and prognosis of primary and secondary pancreatic diffuse large B-cell lymphoma (DLBCL) . Methods: Clinical data of patients with pancreatic DLBCL admitted at Shanghai Rui Jin Hospital affiliated with Shanghai Jiao Tong University School of Medicine from April 2003 to June 2020 were analyzed. Gene mutation profiles were evaluated by targeted sequencing (55 lymphoma-related genes). Univariate and multivariate Cox regression models were used to evaluate the prognostic factors of overall survival (OS) and progression-free survival (PFS) . Results: Overall, 80 patients were included; 12 patients had primary pancreatic DLBCL (PPDLBCL), and 68 patients had secondary pancreatic DLBCL (SPDLBCL). Compared with those with PPDLBCL, patients with SPDLBCL had a higher number of affected extranodal sites (P<0.001) and had higher IPI scores (P=0.013). There was no significant difference in the OS (P=0.120) and PFS (P=0.067) between the two groups. Multivariate analysis indicated that IPI intermediate-high/high risk (P=0.025) and double expressor (DE) (P=0.017) were independent adverse prognostic factors of OS in patients with pancreatic DLBCL. IPI intermediate-high/high risk (P=0.021) was an independent adverse prognostic factor of PFS in patients with pancreatic DLBCL. Targeted sequencing of 29 patients showed that the mutation frequency of PIM1, SGK1, BTG2, FAS, MYC, and MYD88 in patients with pancreatic DLBCL were all >20%. PIM1 (P=0.006 for OS, P=0.032 for PFS) and MYD88 (P=0.001 for OS, P=0.017 for PFS) mutations were associated with poor OS and PFS in patients with SPDLBCL. Conclusion: There was no significant difference in the OS and PFS between patients with PPDLBCL and those with SPDLBCL. IPI intermediate-high/high risk and DE were adverse prognostic factors of pancreatic DLBCL. PIM1, SGK1, BTG2, FAS, MYC, and MYD88 were common mutations in pancreatic DLBCL. PIM1 and MYD88 mutations indicated worse prognosis.

As a severe malignant tumor of the digestive system,the highly invasive pancreatic cancer lacks typical preliminary symptoms. Rapid metastatic dissemination and difficulty in early-stage diagnosis preclude the chance of radical curative resection,hence resulting in a poor overall prognosis in most patients. In recent years,the wide application of the artificial intelligence(AI),represented by machine learning and deep learning,has developed rapidly in the field of medicine. All sorts of models based on AI have been applied to the screening, early diagnosis, treatment, prognosis prediction of patients with pancreatic cancer.Three-dimentional visualization and augmented reality navigation technologies have also been developed and applied in pancreatic cancer surgery.This paper reviews the status quo of AI application in pancreatic cancer from various aspects,and anticipates its future application prospects.

8.The progression of the extent of lymph node dissection in radical resection of pancreatic head cancer.
Chinese Journal of Surgery 2023;61(3):251-255
Pancreatic cancer is a malignant tumor of digestive system with poor prognosis,and surgical resection is still the only hope for a radical cure. Although the current consensus and guidelines describe in detail the standard and extended range of lymph node dissection,the selection of specific range of lymph node dissection and its impact on prognosis are still controversial. Current studies have not only proposed some improved extent of lymph node dissection, such as total mesopancreas excision and Heidelberg triangle dissection, but also suggested different extent of lymph node dissection for ventral and dorsal pancreatic head cancer. In addition, the prognosis of pancreatic head cancer in uncinate process and non-uncinate process is different after para-aortic lymph node dissection, which is worthy of further study. Neoadjuvant therapy or conversion therapy provides more surgical opportunities for patients with pancreatic cancer. For these patients, Heidelberg triangle dissection has potential value in improving prognosis. This paper summarizes the exploration and latest progress of standard and extended lymph node dissection, lymph node dissection of specific site of pancreatic head cancer and the extent of lymph node dissection after neoadjuvant/transformation therapy in recent years.

OBJECTIVE:
To investigate the effect of ferulic acid, a natural compound, on pancreatic beta cell viability, Ca2+ channels, and insulin secretion.
METHODS:
We studied the effects of ferulic acid on rat insulinoma cell line viability using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide viability assay. The whole-cell patch-clamp technique and enzyme-linked immunosorbent assay were also used to examine the action of ferulic acid on Ca2+ channels and insulin secretion, respectively.
RESULTS:
Ferulic acid did not affect cell viability during exposures up to 72 h. The electrophysiological study demonstrated that ferulic acid rapidly and concentration-dependently increased L-type Ca2+ channel current, shifting its activation curve in the hyperpolarizing direction with a decreased slope factor, while the voltage dependence of inactivation was not affected. On the other hand, ferulic acid have no effect on T-type Ca2+ channels. Furthermore, ferulic acid significantly increased insulin secretion, an effect inhibited by nifedipine and Ca2+-free extracellular fluid, confirming that ferulic acid-induced insulin secretion in these cells was mediated by augmenting Ca2+ influx through L-type Ca2+ channel. Our data also suggest that this may be a direct, nongenomic action.
CONCLUSION
This is the first electrophysiological demonstration that acute ferulic acid treatment could increase L-type Ca2+ channel current in pancreatic β cells by enhancing its voltage dependence of activation, leading to insulin secretion.

OBJECTIVES:
To investigate the effects and molecular mechanisms of asiatic acid on β-cell function in type 2 diabetes mellitus (T2DM).
METHODS:
The T2DM model was established by high fat diet and streptozotocin injection in ICR mice, and the effects of asiatic acid on glucose regulation were investigated in model mice. The islets were isolated from palmitic acid-treated diabetic mice. ELISA was used to detect the glucose-stimulated insulin secretion, tumor necrosis factor (TNF)-α and interleukin (IL)-6. ATP assay was applied to measure ATP production, and Western blotting was used to detect protein expression of mature β cell marker urocortin (Ucn) 3 and mitofusin (Mfn) 2. The regulatory effects of asiatic acid on glucose-stimulated insulin secretion (GSIS) and Ucn3 expression were also investigated after siRNA interference with Mfn2 or treatment with TNF-α.
RESULTS:
Asiatic acid with the dose of 25 mg·kg-1·d-1 had the best glycemic control in T2DM mice and improved the homeostasis model assessment β index. Asiatic acid increased the expression of Mfn2 and Ucn3 protein and improved the GSIS function of diabetic β cells in vitro and in vivo (both P<0.05). Moreover, it improved the ATP production of islets of T2DM mice in vitro (P<0.05). Interfering Mfn2 with siRNA blocked the up-regulation of Ucn3 and GSIS induced by asiatic acid. Asiatic acid inhibited islet TNF-α content and increased Mfn2 and Ucn3 protein expression inhibited by TNF-α.
CONCLUSIONS
Asiatic acid improves β cell insulin secretion function in T2DM mice by maintaining the β cell maturity, which may be related to the TNF-α/Mfn2 pathway.
