Abstract
Objective: To identify efficacy and safety of pudendal nerve block in tubing through the third posterior sacral foramen for the treatment of pudendal neuralgia (PN). Methods: A retrospective study with 222 PN patients was conducted in the Department of Pain Management of Beijing Tsinghua Changgung Hospital from January 2020 to April 2023. These patients were divided into two groups based on their treatment methods: pudendal nerve block in tubing through the third posterior sacral foramen (observation group, n=101) and ultrasound-guided pudendal nerve block (control group, n=121). Primary outcome measure was the 90-day postoperative pain relief rate. Secondary outcome measures included visual analog scale (VAS) at 1, 7, 14, 30 and 90 d after surgery, the incidence of tramadol uses after surgery, postoperative self-rating anxiety scale (SAS) scores and the incidence of adverse events. Factors that influenced pain relief within 90 days after surgery were analyzed by using binary logistic regression analysis. Results: Observation group included 34 males and 67 females, aged (49.8±16.0) years old. Control group included 38 males and 83 females, aged (43.7±14.0) years old. The 90-day postoperative pain relief rate of the observation group patients was 38.6% (39/101), which was higher than the 24.0% (29/121) of the control group patients (P=0.018). Both the observation group and the control group showed an interaction effect of time and group after treatment for VAS scores (both P<0.05). In intra-group comparison, the VAS scores at 1, 7, 14, 30 and 90 d after treatment in both groups were lower than those before treatment (all P<0.05). In inter-group comparison, the differences of the VAS scores were not statistically significant in the observation group compared with those in the control group at 1, 7, 14, 30 and 90 d after surgery (all P>0.05). The SAS score of the observation group at 90 d after surgery was 51.5±6.2, which was lower than the 53.4±5.8 of the control group (P=0.022). There was no statistically significant difference in the incidence of postoperative tramadol uses and adverse events between the two groups (both P>0.05). Pudendal nerve block in tubing through the third posterior sacral foramen was a protective factor for pain postoperative relief in PN patients at 90 d after surgery (OR=1.92, 95%CI: 1.05-3.48, P=0.033). Conclusion: Pudendal nerve block in tubing through the third posterior sacral foramen is a safe and effective minimally invasive treatment. It has a higher postoperative pain relief rate within 90 d after surgery, without increasing the uses of postoperative rescue analgesics and the incidence of adverse events.

Abstract
Migratory birds are recently recognized as Vibrio disease vectors, but may be widespread transporters of Vibrio strains. We isolated Vibrio cholerae (V. cholerae) and Vibrio metschnikovii (V. metschnikovii) strains from migratory bird epidemic samples from 2017 to 2018 and isolated V. metschnikovii from migratory bird feces in 2019 from bird samples taken from the Inner Mongolia autonomous region of China. To investigate the evolution of these two Vibrio species, we sequenced the genomes of 40 V. cholerae strains and 34 V. metschnikovii strains isolated from the bird samples and compared these genomes with reference strain genomes. The pan-genome of all V. cholerae and V. metschnikovii genomes was large, with strains exhibiting considerable individual differences. A total of 2,130 and 1,352 core genes were identified in the V. cholerae and V. metschnikovii genomes, respectively, while dispensable genes accounted for 16,180 and 9,178 of all genes for the two strains, respectively. All V. cholerae strains isolated from the migratory birds that encoded T6SS and hlyA were non-O1/O139 serotypes without the ability to produce CTX. These strains also lacked the ability to produce the TCP fimbriae nor the extracellular matrix protein RbmA and could not metabolize trimetlylamine oxide (TMAO). Thus, these characteristics render them unlikely to be pandemic-inducing strains. However, a V. metschnikovii isolate encoding the complete T6SS system was isolated for the first time. These data provide new molecular insights into the diversity of V. cholerae and V. metschnikovii isolates recovered from migratory birds.

Abstract
In light of the effects of gastrointestinal (GI) peptides on bile secretion and biliary tract mobility, we studied the effects of GI peptides on gallstone formation in guinea pigs fed on low protein lithogenic diet. The peptides under study included cholecystokinin octapeptide (CCK-8), vasoactive intestinal peptide (VIP), somatostatin (SRIF), secretin (SEC), and neurotensin (NT). Hepatic bile flow, electrolytes, and other bile components were also measured. It was found that CCK-8 and VIP suppressed the formation of gallstones and increased hepatic bile flow and Na+, K+, Cl- output significantly. On the other hand, SRIF significantly promoted gallstone formation. The rates of gallstone formation in CCK-8, VIP, and SRIF treated guinea pigs were 15.4%, 23.5%, and 88.0%, respectively, in contrast to 56.8% in the control group. The inhibitory effect of CCK-8 and promoting effect of SRIF on gallstone formation were dose-dependent.

Abstract
CA 19-9 is a carbohydrate antigen isolated from human colon carcinoma cell line, and is reportedly a tumor marker for pancreatic carcinoma. In this study we determined serum CA 19-9 in 71 normal subjects, 103 patients with benign digestive diseases, 85 patients with periampullary cancers, and 160 patients with other digestive cancers. Serum CA 19-9 was elevated only in 2.3% of normals and benign digestive disease patients, whereas it was increased in 72.7%, 86.4%, and 89.5% of pancreatic, ampullary, and choledochal carcinoma patients, respectively. Of other digestive cancer patients, it was elevated in 23.8%. In addition, very high serum CA 19-9 (greater than 120 u/m) was more often observed in patients with pancreatic, ampullary, and biliary cancer patients than in GL cancer patients (54.1% vs 9.4%, p less than 0.001). In 18 normal subjects and 68 patients with benign and malignant diseases, it was found that CA 19-9 content in the pancreatic juice was significantly increased in pancreatic, ampullary, and choledochal cancer patients, whereas in chronic pancreatitis patients it was normal, indicating that it is a specific and valuable tumor marker in differential diagnosis of pancreatic cancer.

Abstract
The effects of vasoactive intestinal peptide (VIP), somatostatin (SRIF), neurotensin (NT), cholecystokinin octapeptide (CCK-8), and secretin (SEC) on the intestinal absorption of amino acid were investigated. Six groups of Wistar rats were studied: (1) controls; (2) VIP treated; (3) SRIF treated; (4) NT treated; (5) CCK-8 treated; (6) SEC treated. [3H]Leucine was given intraluminally through a cannula at the ligament of Treitz, a number of blood samples were obtained through a superior mesenteric vein catheter 1-60 min after administration of [3H]leucine, and the radioactivity of plasma was measured to evaluate the absorption of [3H]leucine. It was shown that VIP and SRIF significantly inhibited the absorption of [3H]leucine (by 59.1% and 38.7%, respectively), whereas NT, CCK-8, and SEC significantly enhanced absorption (by 44.2%, 49.6%, and 39.1%, respectively). Radioimmunoassays of VIP, SRIF, and NT showed that at least some of the hormones or peptides exerted their effects on absorption of leucine at or near their physiological concentrations.

Abstract
The pathophysiological, biochemical, histological, ultrastructural, and immunohistochemical characters of a case of malignant pancreatic islet cell tumor with watery diarrhea syndrome were carefully investigated. Four hormones or mediators--somatostatin (SST), vasoactive intestinal peptide (VIP), serotonin, and prostaglandin E--were markedly elevated in the circulation. The diagnosis was further confirmed by exploratory laparotomy and autopsy. The contents of SST and VIP in tumor tissues were very high. Gel chromatography of tumor extract revealed single peaks for both SST and VIP. Immunohistochemical studies of tumor tissues showed numerous immunoreactive cells to anti-SST, moderate amount of VIP-positive cells, and a few hCG-, insulin-, and glucagon-positive cells. In conclusion, this is an unusual case of Verner-Morrison syndrome in which three kinds of bioactive hormones or mediators were simultaneously secreted; peptides, amine, and prostaglandin.
