Objective To evaluate the efficacy of ultrasound-guided transversus abdominis plane (TAP) block for postoperative analgesia in patients undergoing inguinal hernia repair.Methods Forty ASA Ⅰ or Ⅱ patients,aged 18-79 yr,with body mass index ＜ 30 kg/m2,scheduled for elective unilateral inguinal hernia repair combined spinal-epidural anesthesia,were randomly divided into 2 groups (n =20 each):control group (group C) and ultrasound-guided TAP block group (group B).The ultrasound-guided TAP block was performed at the end of surgery and 20 ml of 0.375 ％ ropivacaine was injected in group B,while the equal volume of normal saline was given in group C.Tramadol was injected intravenously when VAS score ≥ 4 after surgery.VAS scores at rest and during activity were recorded at 4,6,24 and 48 h after surgery.The warm block plane on the blocked side was measured at 24 and 48 h after surgery.The overall satisfaction on analgesia was scored and the time when the patients passed the flatus was recorded.TAP block-related side effects were recorded.Results Four patients required tramadol in group C,while no patients required rescue analgesic in group B.Compared with group C,VAS scores were significantly decreased,the overall satisfaction scores were increased (P ＜ 0.05 or 0.01),and no significant change was found in the time when the patients passed the flatus in group B (P ＞ 0.05).The rate of warm plane block on the blocked side was 80％ at 24 h after surgery and there was not warm block plane in patients at 48 h after surgery in group B.There was not warm block plane in patients at 24 and 48 h after surgery in group C.TAP block-related side effects were not found in group B.Conclusion The efficacy of ultrasound-guided TAP block for postoperative analgesia is better in patients undergoing inguinal hernia repair and the safety is higher.

Objective To evaluate the feasibility and clinical significance of magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of anatomic variants of the extrahepatic biliary tract. Methods The MRCP images of 535 patients who were admitted to The Second Affiliated Hospital of Suzhou University from March 2008 to March 2009 were retrospectively analyzed by two reviewers independently. The anatomic variants of the extrahepatic biliary tract were evaluated by studying the T2-weighted magnetic resonance images. Results The consistency between the two reviewers in the diagnosis of low choledochal joint, medial cystic duct insertion, aberrant hepatic duct, accessory hepatic duct and other anatomic variants was 98% , 99% , 89% , 90% and 100%, respectively (K = 0.86, 0.93, 0.81, 0.82, 1.00). The extrahepatic biliary system was clearly displayed by MRCP in 500 patients, and anatomic variants were observed in 240 patients, including low choledochal joint in 85, parallel cystic duct in 37, medial cystic duct insertion in 82, aberrant hepatic duct in nine, accessory hepatic duct in 10, choledochal cyst in three and high cystic duct in seven. A total of 259 patients underwent operation, and 168 patients had anatomic variants of the extrahepatic biliary tract. Conclusion MRCP imaging enables the accurate assessment of anatomic variants of the extrahepatic biliary system and avoids bile duct injury.

Objective To evaluate the correlation between low choledochal joint and common bile duct stones(CBDS)by magnetic resonance cholangiopancreatography(MRCP).Methods The clinical data of 129 patients without intrahepatic calculus after cholecystectomy receiving MRCP from March 2008 to August 2009 were retrospectively analyzed.MRCP images and T2WIs were analyzed independently by 2 doctors to classify anatomic variants of cystic duct and calculus.Results CBDS was found in 49 and low insertion of the cystic duct in 31 of the 129 patients(38% vs.24%).For the latter 31 patients, low insertion of the cystic duct with CBDS was found in 17.The analysis showed that low choledochal joint were associated with CBDS(x2 =4.921, P=0.027).Conclusion There is a certain correlation between low insertion of the cystic duct and CBDS.The low insertion of the cystic duct is one of the risk factors for calculus of the common bile duct.

Objective: To investigate the characteristics of the breakthrough cases of mumps in Ningbo City, Zhejiang Province from 2018 to 2023, so as to provide insights into improving prevention and control measures for mumps. Methods: Data of mumps cases and mumps containing vaccine (MuCV) vaccination in Ningbo City from 2018 to 2023 were collected through the Infectious Disease Reporting Information System of Chinese Disease Prevention and Control Information System and Zhejiang Immunization Planning Information System. The population distribution characteristics and MuCV immunization history of mumps breakthrough cases were described. The impacts of the final immunization age and immunization interval on the age of onset were analyzed. Results: A total of 6 643 mumps cases were reported in Ningbo City from 2018 to 2023, with an average incidence rate of 11.72/105. There were 5 142 breakthrough cases (77.40%), including 3 173 males (61.71%) and 1 969 females (38.29%). The median age of onset was 6.00 (interquartile range, 4.00) years. There were 2 487 cases in preschool children (48.37%) and 2 232 cases in students (43.41%). There were 4 736 one-dose breakthrough cases (92.10%) and 406 two-dose breakthrough cases (7.90%). The proportion of two-dose breakthrough cases among all mumps cases increased from 1.00% in 2018 to 25.32% in 2023. Among individuals born after December 2018, the median age of onset of two-dose breakthrough cases was 3.00 (interquartile range, 1.00) years, which was older than that of one-dose breakthrough cases at 1.00 (interquartile range, 2.00) year (P<0.05). The ages of onset of mumps breakthrough cases differed significantly with varying final immunization ages and immunization intervals (both P<0.05). Conclusions The breakthrough cases of mumps in Ningbo City from 2018 to 2023 were mainly males, preschool children and students. The proportion of two-dose breakthrough cases increased, and the age of onset delayed.

Objective Previous studies of peripheral nerves activation during magnetic stimulation have focused almost exclusively on the cause of high external parallel electric field along the nerves, whereas the effect of the transverse component has been ignored. In the present paper, the classical cable function is modified to represent the excitation of peripheral nerves stimulated by a transverse electric field during magnetic stimulation. Methods Responses of the Ranvier nodes to a transverse-field are thoroughly investigated by mathematic simulation. Results The simulation demonstrates that the excitation results from the net inward current driven by an external field. Based on a two-stage process, a novel model is introduced to describe peripheral nerves stimulated by a transverse-field. Based on the new model, the classical cable function is modified. Conclusion Using this modified cable equation, the excitation threshold of peripheral nerves in a transverse field during MS is obtained. The modified cable equation can be used to represent the response of peripheral nerves by an arbitrary electric field.
