Objective To investigate the influence and safety of ultrasound-guided transverses abdominis plane block on general analgesia in patients undergoing lower abdominal operation. Methods Three hundred patients scheduled for lower abdominal operation under general anesthesia were randomly divided into 2 groups:ropivacaine group (group A,n = 151) and normal saline group (group B,n = 149). After the operation ultrasound-guided TAP was performed and 0.375% ropivacaine 20 mL was injected in group A while the equal volume of normal saline was used instead in group B. VAS score, Ramsay sedation score, and Bruggrmann comfort scale (BCS) score were recorded at the time points of 2, 4, 6, 8, 12, 24 hours postoperatively. The adverse reactions such as nausea, vomiting, urinary retention, motor and sensory disorders were also recorded. Results No significant difference in the demographic characteristics such as sex , age , height and weight , was observed between the two groups (P > 0.05). VAS score and BCS score were significantly different (P < 0.05) in group A compared with group B. There were no significant differences (P > 0.05) between the two groups in Ramsay score and adverse reactions. Conclusion Ultrasound-guided TAP block can effectively meet the needs of patients with postoperative analgesia and enhance the comfort after the lower abdominal operation.

Objective:To explore the application effect of optimizing diet management in patients with hyperphosphatemia.Methods:Seventy-seven patients who underwent regular hemodialysis in the blood purification department of the First Affiliated Hospital of Guangxi Medical University from September 2018 to June 2019 were selected. Patients were randomly divided into control group (39 cases) and intervention group (38 cases) by the method of random number table. The control group received routine nursing, while the intervention group received optimized dietary management intervention. The blood phosphorus, blood calcium, hemoglobin, albumin, dietary phosphorus related knowledge level and phosphorus control diet compliance of the two groups before and after the intervention were compared respectively.Results:After 3 months of intervention, the scores of knowledge about food phosphorus, compliance of phosphorus control diet and total score of the intervention group were (22.00±3.92), (34.82±4.69) and (56.82±7.48) points, which were higher than (18.46±3.57), (30.54±3.52) and (49.00±6.13) points of the control group, the difference was statistically significant ( tvalues were 4.146, 4.536 and 5.022, P<0.05). After 6 months of intervention, the scores of knowledge about food phosphorus, compliance of phosphorus control diet and total score of the intervention group were (25.74±3.36), (41.63±5.27) and (67.37±7.67) points, which were higher than (20.97±3.81), (32.36±4.38) and (53.33±6.80) points of the control group, the difference was statistically significant ( tvalues were 5.815, 8.403 and 8.504, P<0.05). After 3 months of intervention, the blood phosphorus level in the intervention group was 1.81 (1.67, 2.10) mmol/L, which was lower than 2.13 (1.87, 2.32) mmol/L in the control group, the difference was statistically significant ( Zvalue was-3.237, P<0.05). After 6 months of intervention, the blood phosphorus level in the intervention group was 1.75 (1.63, 1.91) mmol/L, which was lower than that in the control group 1.90 (1.83, 2.13) mmol/L, and the difference was statistically significant ( Zvalue was-3.343, P<0.01). Conclusion:Optimizing dietary management can improve patients' knowledge level of food phosphorus and dietary compliance of phosphorus control, effectively reduce blood phosphorus level, and have no obvious effect on nutritional status.

OBJECTIVE: To study the microanatomy by endoscope-assisted via retrolabyrinthine approach. METHOD: Nineteen cadaveric heads fixed with formalin were dissected in our study. The data that endoscope could be extent and the distance between the important point were measured. By simulated the retrolabyrinthine approach, endoscope was placed to observe the nerves and vessels, the distance between nerves and the central point of the anterior edge of sigmoid sinus were measured. RESULT: The distance from the inferior margin of petrous ridge to the upper bound of endolymphatic sac was (9.93+/-1.52)mm; and from superior margin of petrous ridge to the inferior margin common bony crus was (4.64+/-0.91)mm;and from the intersection of posterior semicircular canal to the anterior wall of sigmoid was (7.85+/-1.47)mm on the left, and (5.69+/-1.68)mm on the right. The distance from inferior margin common bony crus to the anterior wall of sigmoid was (13.9+/-1.71)mm on the left, and (11.31+/-2.03)mm on the right. The trochlear nerve and abducent nerve could be observed under endoscope. The relationship between the trigeminal nerve, acoustic nerve and the vessels could be identified clearly. The distance from the central point of the anterior edge of sigmoid to the roots of the trigeminal nerve, facial nerve, vestibulocochlear nerve and glossopharyngeal nerve were (29.88+/-2.77) mm, (32.04+/-2.04) mm, (29.17+/-1.65) mm, (35.49+/-1.53) mm respectively. CONCLUSION The visual field of the cerebellopontine angle appear wider by the endoscope assisted retrolabyrinthine approach. Nerves, vessel, internal acoustic pore, jugular foramen region can be clearly seen. Some minimal invasive surgery can be done by this approach.

Objective:To investigate the correlation between the enhancement characteristics in arterial phase and the prognosis of patients with massive intrahepatic cholangiocarcinoma (IMCC).Methods:The imaging and clinical data of 92 patients with IMCC who were pathologically confirmed and underwent enhanced MRI or CT in Central Hospital of Lishui from June 2004 to February 2019 were retrospectively analyzed. According to the enhancement pattern of the primary lesion in the arterial phase, patients were divided into rich arterial blood supply group （17 cases） and deficient arterial blood supply group （75 cases）. The clinical data and imaging features of these patients were studied. Differences between measurement data and count data between the two groups were compared using t test and Fisher test. Kaplan-Meier analysis and log-rank test were used to analyze overall survival. The Cox regression multivariate analysis was used to study the relationship between the variables and the risk of death. Result:The enlargement of lymph nodes, long diameter of the primary lesion, CA19-9, treatment and HPD around the primary lesion in arterial phase were statistically different in the two groups ( P<0.05), others were no statistical difference. CA19-9>200 U/ml, lymph node enlargement, HPD around the primary lesion in arterial phase and deficient arterial blood supply were independent factors for the prediction of prognosis in IMCC patients with surgery ( P values were 0.008, 0.002, 0.049 and 0.005, respectively). Lymph node enlargement and deficient arterial blood supply were independent risk factors for the prediction of prognosis in IMCC patients with surgery ( P values are 0.049 and 0.045, respectively). Conclusion:The blood supply characteristics of arterial phase are independent factors for the prognosis of patients with IMCC.
