Abstract
BACKGROUND Microbiota profiles differ between patients with pancreatic cancer and healthy people, and understanding these differences may help in early detection of pancreatic cancer. Saliva sampling is an easy and cost-effective way to determine microbiota profiles compared to fecal and tissue sample collection.
AIM To investigate the saliva microbiome distribution in patients with pancreatic adenocarcinoma (PDAC) and the role of oral microbiota profiles in detection and risk prediction of pancreatic cancer.
METHODS We conducted a prospective study of patients with pancreatic cancer (n = 41) and healthy individuals (n = 69). Bacterial taxa were identified by 16S ribosomal ribonucleic acid gene sequencing, and a linear discriminant analysis effect size algorithm was used to identify differences in taxa. Operational taxonomic unit values of all selected taxa were converted into a normalized Z-score, and logistic regressions were used to calculate risk prediction of pancreatic cancer.
RESULTS Compared with the healthy control group, carriage of Streptococcus and Leptotrichina (z-score) was associated with a higher risk of PDAC [odds ratio (OR) = 5.344, 95% confidence interval (CI): 1.282-22.282, P = 0.021 and OR = 6.886, 95%CI: 1.423-33.337, P = 0.016, respectively]. Veillonella and Neisseria (z-score) were considered a protective microbe that decreased the risk of PDAC (OR = 0.187, 95%CI: 0.055-0.631, P = 0.007 and OR = 0.309, 95%CI: 0.100-0.952, P = 0.041, respectively). Among the patients with PDAC, patients reporting bloating have a higher abundance of Porphyromonas (P = 0.039), Fusobacterium (P = 0.024), and Alloprevotella (P = 0.041); while patients reporting jaundice had a higher amount of Prevotella (P = 0.008); patients reporting dark brown urine had a higher amount of Veillonella (P = 0.035). Patients reporting diarrhea had a lower amount of Neisseria and Campylobacter (P = 0.024 and P = 0.034), and patients reporting vomiting had decreased Alloprevotella (P = 0.036).
CONCLUSION Saliva microbiome was able to distinguish patients with pancreatic cancer and healthy individuals. Leptotrichia may be specific for patients living in Sichuan Province, southwest China. Symptomatic patients had different bacteria profiles than asymptomatic patients. Combined symptom and microbiome evaluation may help in the early detection of pancreatic cancer.

Abstract
BACKGROUND Primary hepatic myelolipoma is a rare hepatic mesenchymal tumor mixed by adipose tissue and bone marrow, and there is a lack of general guidelines related to its epidemiology and clinical management. CASE SUMMARY A 26-year-old woman was admitted to our department complaining of a newly found tumor on her left lobe of the liver. The tumor was painless and not associated with any systemic or localized compressive symptoms. Serological tests disclosed a slight increase of gamma-glutamyl transpeptidase (70.0 U/L) and total bilirubin (19.2 μmol/L). Ultrasonography showed a mass about 5.0 cm × 5.0 cm in size that was located in the left lobe of the liver and displayed hyperechoic and well-encapsulated characteristics. Surgical resection was applied, and the following histopathological examination observed a variable proportion of myeloid tissues scattering throughout mature fibrotic adipose tissues, in which myeloid, erythroid, and megakaryocytic cells can be found in magnified view. The follow-up did not show any changes 6 mo after surgery. CONCLUSION This case highlights an extremely rare hepatic mesenchymal tumor, the primary hepatic myelolipoma, and discloses the common characteristics behind this disease and gives clinical recommendations.

Abstract
OBJECTIVES To investigate the effect of tumor necrosis factor -related weak inducer of apoptosis (TWEAK)/fibroblast growth factor-inducible 14 (Fn14) on the proliferation and growth of pancreatic cancer. METHODS Human pancreatic cancer (50 cases), chronic pancreatitis (40 cases) and normal pancreatic tissues (30 cases) were collected in West China Hospital from January 2012 to December 2013. TWEAK and Fn14 expressions in these tissues were checked with hematoxylin-eosin (HE) staining and immunohistochemistry method. Relationship between TWEAK expression and clinicopathological features of pancreatic cancer was analyzed. RESULTS TWEAK expression rate was 36% (18/50) in pancreatic cancer, higher than that in chronic pancreatitis (17.5%, 7/40) and normal pancreatic tissues (13.3%, 4/30) ( P<0.05) .Expression intensity of TWEAK in three groups was also obviously ( P<0.05). The expression rate of Fn14 was 4.0% in pancreatic cancer , 7.0% in normal pancreatic tissues , and 0% in chronic pancreatitis. TWEAK positive expression rate and high expression rate in pancreatic cancer were higher in IIB group ( P<0.05). Pathological grade was not related to TWEAK expression. CONCLUSIONS TWEAK/Fn14 involved in the progression of pancreatic cancer. In the tissue of pancreatic cancer, TWEAK was highly expressed, and Fn14 was lowly expressed.

Abstract
AIM: To identify the possible predictors of early complications after the initial intervention in acute necrotizing pancreatitis.
METHODS: We collected the medical records of 334 patients with acute necrotizing pancreatitis who received initial intervention in our center. Complications associated with predictors were analyzed.
RESULTS: The postoperative mortality rate was 16% (53/334). Up to 31% of patients were successfully treated with percutaneous catheter drainage alone. The rates of intra-abdominal bleeding, colonic fistula, and progressive infection were 15% (50/334), 20% (68/334), and 26% (87/334), respectively. Multivariate analysis indicated that Marshall score upon admission, multiple organ failure, preoperative respiratory infection, and sepsis were the predictors of postoperative progressive infection (P < 0.05). Single organ failure, systemic inflammatory response syndrome upon admission, and C-reactive protein level upon admission were the risk factors of postoperative colonic fistula (P < 0.05). Moreover, preoperative Marshall score, organ failure, sepsis, and preoperative systemic inflammatory response syndrome were the risk factors of postoperative intra-abdominal bleeding (P < 0.05).
CONCLUSION: Marshall score, organ failures, preoperative respiratory infection, sepsis, preoperative systemic inflammatory response syndrome, and C-reactive protein level upon admission are associated with postoperative complications.

Abstract
OBJECTIVE To demonstrate the effectiveness of quality improvement methods to monitor and improve administration of cotrimoxazole (CTX) prophylaxis to improve health outcomes among adults living with HIV/AIDS in low resource countries. DESIGN Program evaluation. SETTING HIV/AIDS health care facilities in Uganda, Mozambique, Namibia and Haiti. INTERVENTION Performance measures based on national guidelines are developed in each country. These may include CD4 monitoring, ART adherence and uptake of CTX prophylaxis. CTX prophylaxis is routinely selected, because it has been shown to reduce HIV-related morbidity and mortality. Patient records are sampled using a standard statistical table to achieve a minimum confidence interval of 90% with a spread of ±8% in participating clinics. If an electronic medical record is available, all patients are reviewed. Routine review of performance measures, usually every 6 months, is conducted to identify gaps in care. Improvement interventions are developed and implemented at health facilities, informed by performance results, and local/national public health priorities. MAIN OUTCOME MEASURE Median clinic rates of CTX prophylaxis. RESULTS Median performance rates of CTX prophylaxis generally improved for adult HIV+ patients between 2006 and 2013 across countries, with median clinic rates higher than baseline at follow-up in 16 of 18 groups of clinics implementing CTX -focused improvement projects. CONCLUSIONS Quality management offers a data-driven method to improve the quality of HIV care in low resource countries. Application of improvement principles has been shown to be effective to increase the rates of CTX prophylaxis in national HIV programs in multiple countries.

Abstract
AIM: To investigate the effect of preoperative biliary drainage (PBD) in jaundiced patients with hilar cholangiocarcinoma (HCCA) undergoing major liver resections.
METHODS: An observational study was carried out by reviewing a prospectively maintained database of HCCA patients who underwent major liver resection for curative therapy from January 2002 to December 2012. Patients were divided into two groups based on whether PBD was performed: a drained group and an undrained group. Patient baseline characteristics, preoperative factors, perioperative and short-term postoperative outcomes were compared between the two groups. Risk factors for postoperative complications were also analyzed by logistic regression test with calculating OR and 95%CI.
RESULTS: In total, 78 jaundiced patients with HCCA underwent major liver resection: 32 had PBD prior to operation while 46 did not have PBD. The two groups were comparable with respect to age, sex, body mass index and co-morbidities. Furthermore, there was no significant difference in the total bilirubin (TBIL) levels between the drained group and the undrained group at admission (294.2 ± 135.7 vs 254.0 ± 63.5, P = 0.126). PBD significantly improved liver function, reducing not only the bilirubin levels but also other liver enzymes. The preoperative TBIL level was significantly lower in the drained group as compared to the undrained group (108.1 ± 60.6 vs 265.7 ± 69.1, P = 0.000). The rate of overall postoperative complications (53.1% vs 58.7%, P = 0.626), reoperation rate (6.3% vs 6.5%, P = 1.000), postoperative hospital stay (16.5 vs 15.0, P = 0.221) and mortality (9.4% vs 4.3%, P = 0.673) were similar between the two groups. In addition, there was no significant difference in infectious complications (40.6% vs 23.9%, P = 0.116) and noninfectious complications (31.3% vs 47.8%, P = 0.143) between the two groups. Univariate and multivariate analyses revealed that preoperative TBIL > 170 μmol/L (OR = 13.690, 95%CI: 1.275-147.028, P = 0.031), Bismuth-Corlette classification (OR = 0.013, 95%CI: 0.001-0.166, P = 0.001) and extended liver resection (OR = 14.010, 95%CI: 1.130-173.646, P = 0.040) were independent risk factors for postoperative complications.
CONCLUSION: Overall postoperative morbidity and mortality rates after major liver resection are not improved by PBD in HCCA patients with jaundice. Preoperative TBIL > 170 μmol/L, Bismuth-Corlette classification and extended liver resection are independent risk factors linked to postoperative complications.

Abstract
Ohmefentanyl (Ohm, N[1-(beta-hydroxy-beta-phenylethyl)-3-methyl-4- piperidyl]-N-phenylpro-pronamide), designed and synthesized by our laboratory, is a highly selective mu receptor agonist. After somatic cell fusion between splenocytes of BALB c mice, immunized by Ohm-BSA conjugate and NS-1 myeloma cells, 2 lines of hybridoma (D2 and F4) secreting monoclonal anti-Ohm antibodies (MAb) were obtained. Saturation and competition experiments showed that MAb-D2 and MAb-F4 bound to Ohm-BSA with high affinity and high specificity. Using radioligand binding assay and bioassay, we also found that MAb-D2 and MAb-F4 inhibited [3H] Ohm binding to rat brain opioid receptors in a dose-dependent manner and antagonized the effect of Ohm on the contraction of guinea pig ileum induced by electric field stimulation. These results suggested that MAb-D2 and MAb-F4 were 2 monoclonal antibodies specific for Ohm and could be useful as functional antagonists of Ohm.
