To investigate the mechanisms underlying the cholinergic agonist carbachol-induced cardiovascular responses, changes of renin-angiotensin system were examined in fetal hormonal systems. In the ovine fetal model under stressless condition, the cardiovascular function was recorded. Blood samples were collected before (during baseline period) and after the intravenous administration of carbachol. Simultaneously, the levels of angiotensin I (Ang I), angiotensin II (Ang II) and vasopressin in the fetal plasma were detected by immunoradiological method. Also, blood gas, plasma osmolality and electrolyte concentrations were analyzed in blood samples. Results showed that in chronically prepared ovine fetus, intravenous infusion of carbachol led to a significant decrease of heart rate (P < 0.05), and a transient decrease followed by an increase of blood pressure (P < 0.05) within 30 min. After the intravenous infusion of carbachol, blood concentrations of Ang I and Ang II in near-term ovine fetus were both significantly increased (P < 0.05); however, blood concentration of vasopressin, values of blood gas, electrolytes and plasma osmolality in near-term ovine fetus were not significantly changed (P > 0.05). Blood levels of Ang I and Ang II in the atropine (M receptor antagonist) + carbachol intravenous administration group was lower than those in the carbachol group without atropine administration (P < 0.05). In conclusion, this study indicates that the near-term changes of cardiovascular system induced by intravenous administration of carbachol in ovine fetus, such as blood pressure and heart rate, are associated with the changes of hormones of circulatory renin-angiotensin system.

OBJECTIVETo investigate the diagnostic value of FICTION (Fluorescence Immunophenotyping and Interphase Cytogenetics as a Tool for the Investigation of Neoplasms) technique, combining immunofluorescence and fluorescence in situ hybridization (FISH), to detect genetic aberrations in multiple myeloma (MM).

METHODSBone marrow samples were collected from 18 MM and 2 plasma cell leukemia (PCL) patients. Probes targeting IgH and MMSET were prepared using a Nick Translation Kit from Bacterial artificial chromosome (BAC) clones. The immunophenotyping was achieved via the CD138 tyramide signal amplification (TSA)-mediated immunofluorescence, followed by FISH with the prepared probes \[t(4;14), t(11;14), t(14;16)\] and the commercial deletion probes (13q and p53) to detect common genetic aberrations in MM.

RESULTSAll the 20 samples were assayed with the probes mentioned above, and revealed 4 cases with t(4;14), 6 with t(11;14), 1 with t(14;16), 3 with p53 deletion; and 8 with 13q deletion. The remaining 4 cases had none of the 5 aberrations.

CONCLUSIONFICTION technique facilitates the detection of genetic abnormalities of MM in situ; enhances both efficiency and sensitivity of positive detection, thus, could be used as the screening test of molecular diagnosis of MM to guide coming-up risk-adapted therapy and evaluate prognosis.

Objective To study the anatomical classification and surgical management of communicating tumors invading the anterior or middle skull base. Methods According to the location and growth direction of the tumors, the communicating tumors invading the anterior or middle skull base in 29 patients were classified into 4 types, namely fronto-naso-orbital tumors in 16 cases, middle-lateral cranial base tumors in 8 cases, central-medial skull base tumors in 4 cases and petrous bone-jugular foramen tumor in 1 case. Based on this classification, extended transbasal approach (13 cases), supraorbital-pterional approach (9 cases), fronto-temporal approach (3 cases), ffontotemporal-orbitozygomatic approach (3 cases) and transpetrol approach (1 case) were adopted for tumor resection and skull base defect reconstruction. In the transbasal approach group, the surgery was performed also through transnasal endoscopic approaches. Results Twenty-four patients underwent total tumor resection and 5 had subtotal tumor resection. No operative death or serious complications (e.g. intracranial infection, cerebrospinal fluid leakage or meningoencephalocele) occurred after the operations. Conclusion Classification of the communicating tumors invading the anterior or middle skull base according to their location and growth direction facilitates planning of the surgical approaches for tumor resection and skull base defect reconstruction.

Aim To study the biliary excretion characteristics of berberine,palmatine and jateorhizine in rat hepatocytes.Methods Berberine,palmatine and jateorhizine were incubated with the sandwich-cultured rat hepatocytes (SCRH) in standard Ca2+ buffer or Ca2+ free buffer.The accumulation of the three compounds under different conditions were measured by UPLC-MS/MS.The biliary excretion index and biliary clearance were calculated,and the effect of P-gp or Mrp2 inhibitor on the transport of three compounds was also investigated.Results While the incubation time increased,the accumulation of the three compounds also increased.There were obvious differences in accumulation of berberine,palmatine and jateorhizine in incubations treated with standard buffer and calcium-free buffer.The P-gp inhibitors ciclosporin A and verapamil could inhibit the biliary excretion of berberine,palmatine and jateorhizine.However,the Mrp2 inhibitors MK571 and probenecid had no effect on biliary excretion of the three compounds.Conclusions The biliary excretion of berberine,palmatine and jateorhizine is mainly through an active process.They are all the P-gp substrates other than Mrp2 substrates.

Objective:To investigate the effects of transaxillary endoscopic and traditional open radical thyroidectomy on the levels of inflammatory factors in patients with thyroid cancer.Methods:The clinical data of 102 thyroid cancer patients underwent radical thyroidectomy from October 2019 to October 2021 in Xinjiang Medical University Hospital of Chinese Medicine were retrospectively analyzed. Among them, 50 cases underwent transaxillary approach endoscopic radical thyroidectomy (study group), and 52 cases underwent open radical thyroidectomy (control group). The operation related indexes were compared between two groups, including operation time, intraoperative blood loss, postoperative drainage, lymph node clearance and hospital stay; the pain scores 1, 3 and 7 d after operation were recorded; the levels of interleukin-6 (IL-6), interleukin-10 (IL-10), galectin-3 (Gal-3) and tumor necrosis factor-α (TNF-α) before operation and 1 d after operation were measured by enzyme-linked immunosorbent assay; the postoperative complications were recorded, including hoarseness, limb numbness, cough after drinking water and hypocalcemia; and the cosmetic satisfaction was followed up 3 months after discharge, and the recurrence was observed by CT 6 months after discharge.Results:The operation time in study group was significantly longer than that in control group: (88.69 ± 15.16) min vs. (61.47 ± 15.48) min, while the intraoperative blood loss, postoperative drainage and hospital stay were significantly lower in control group: (51.21 ± 10.06) ml vs. (85.46 ± 11.37) ml, (98.29 ± 30.61) ml vs. (117.47 ± 30.25) ml and (5.35 ± 0.54) d vs. (7.72 ± 0.61) d, and there were statistical differences ( P<0.01); there was no statistical difference in lymph node clearance between two groups ( P>0.05). The pain score 1 and 3 d after operation in study group was significantly lower than that in control group: (5.13 ± 1.07) scores vs. (7.87 ± 1.46) scores and (4.22 ± 1.35) scores vs. (6.42 ± 1.28) scores, and there were statistical differences ( P<0.05); there was no statistical difference in pain score 7 d after operation between two groups ( P>0.05). There were no statistical differences in IL-6, IL-10, TNF-α and Gal-3 between two groups ( P>0.05); the IL-6, IL-10, TNF-α and Gal-3 1 d after operation in study group were significantly lower than those in control group: (26.27 ± 3.14) ng/L vs. (29.22 ± 4.52) ng/L, (7.54 ± 2.31) ng/L vs. (10.92 ± 2.54) ng/L, (14.98 ± 3.76) μg/L vs. (23.65 ± 2.46) μg/L and (3.54 ± 0.48) μg/L vs. (4.48 ± 0.63) μg/L, and there were statistical differences ( P<0.01). There was no statistical difference in the incidence of total complications between two groups ( χ2 = 1.73, P>0.05). The total satisfaction rate in study group was significantly higher than that in control group: 94.0% (47/50) vs. 78.8% (41/52), and there was statistical difference ( χ2 = 4.94, P<0.05). The patients were followed up for 6 months after discharge, and there was no recurrence. Conclusions:The transaxillary approach endoscopic radical thyroidectomy can reduce intraoperative blood loss, length of stay, postoperative drainage, postoperative pain, and to some extent inhibit inflammatory response. It can improve the postoperative cosmetic satisfaction, reduce the incidence of postoperative complications, and does not increase the recurrence rate
