Methods The maximum tolerated dose( MTD)of water and ethanol extracts of Radix millettiae speciosae were measured for the safety evaluation. Results Maximal tolerated dose( MTD)of water extract was higher than 1 000 g·kg-1 ,which equaled to 110 times the dose for human adults(60 kg). MTD of ethanol extract was higher than 1 700 g·kg-1 ,which equaled to 186 times the dose for human adults(60 kg). Conclusion Radix millettiae speciosae does not have obvious toxicity,thus its routine clinical dose is safe and feasible.

Objective To investigate the electrophysiological characteristics of carpal tunnel syndrome (CTS) and CTS-associated cervical spondylotic radiculopathy (CSR),and to examine the relationship between CTS and CSR. Methods The clinical characteristics and electrodiagnostic features of 81 patients with CTS and 20 patients with both CTS and CSR (the double crush,DC) were analyzed and compared.The data were analyzed according to the severity of the deficit in median nerve conduction using electromyography. Results The 81 patients with CTS had 123 median nerves with abnormal conduction (39 cases with unilateral abnormalities and 42 cases with bilateral abnormalities).The 20 patients with DC had 31 median nerves with abnormal conduction (9 cases with unilateral abnormalities and 11 cases with bilateral abnormalities).The rate of abnormal sensory nerve conduction velocity (SCV) was 100％ in C6 and C7 level radiculopathies.The rate of abnormal distal motor latency (DML) was 92.31％ in C5 level radiculopathies.There was a statistically significant difference between CTS and DC in the rate of abnormal SCV from the middle finger to the wrist.The other electrodiagnostic data were not significantly different between the CTS and DC patients.Neurophysiological tests were used to grade CTS into categories according to the American Association of Electrodiagnostic Medicine's criteria,but there was no statistically significant difference between CTS and DC. Conclusions CSR lesions on a proximal nerve root may cause the nerve to be more susceptible to distal injury and increase the risk of CTS.The findings support the DC hypothesis,but DC on a median nerve did not result in more severe injury than a single crush.

Objective To explore the clinical effects of S-1 single agent chemotherapy for the patients undergoing radical resection of cholangiocarcinoma.Methods The clinical data of 51 patients receiving radical resection of cholangiocarcinoma who were admitted to the Second Affiliated Hospital of Zhejiang University from November 2011 to December 2013 were retrospectively analyzed.After radical resection of cholangiocarcinoma,25 patients receiving non-special treatment and 26 patients receiving S-1 single agent chemotherapy were divided into the operation group and chemotherapy group,respectively.S-1 was taken orally twice per day.Forty mg/once of S-1 was applied to patients with the body surface area ＜ 1.25 m2,50 mg/once of S-1 was applied to patients with the body surface area ≥ 1.25 m2 and ＜ 1.50 m2,and 60 mg/once of S-1 was applied to patients with the body surface area ≥ 1.50 m2.The 14 days usage and 7 days withdrawal of S-1 were used as one course of treatment.The standard usage of S-1 was 6-8 courses of treatment.All the patients were followed up by outpatient examination and telephone interview till December 1,2014.Count data were analyzed using the chi-square test.Measurement data with normal distribution were presented as (x) ± s and analyzed using the t test.Survival curve was drawn by the Kaplan-Meier method,and survival analysis was done using the Log-rank test.Results Twenty-six patients in the chemotherapy group finished the courses of chemotherapy without chemotherapy-related death,and 14 patients had chemotherapy adverse reactions with remission after discontinuation of S-1.All the 51 patients were followed up for 5-37 months with a median time of 19 months.The median overall survival time,1-,3-year overall survival rates,tumor-free median survival time and 1-,3-year tumor-free survival rates were 22 months (range,18-27 months),72.3％,42.9％,21 months (range,16-26 months),60.0％,55.0％ in the operation group and 32 months (range,29-35 months),84.6％,44.4％,26 months (range,21-31 months),76.9％,61.9％ in the chemotherapy group,respectively.There was a significant difference in the overall survival between the 2 groups (x2=6.032,P ＜ 0.05).There was no significant difference in the tumor-free survival between the 2 groups (x2=0.498,P ＞ 0.05).Conclusion S-1 single agent chemotherapy after radical resection of cholangiocarcinoma could improve the survival of patients,while no obvious advantages of inhibiting tumor recurrence is observed.

Objective:To study the learning curve in laparoscopic left lateral hepatic sectionectomy.Methods:The clinical data of 62 consecutive patients who underwent left lateral hepatic sectionectomy by a single operator from February 2015 to May 2022 in General Hospital of Northern Theater Command were retrospectively analyzed. There were 22 males and 40 females, with mean ±s.d. of (50.7±11.7) years. The learning curve was depicted and evaluated by using the cumulative summation test. The general information, operation and postoperative indicators of the growth level group and the master level group were compared.Results:The average operation time of the 62 consecutive subjects was (172.9±70.1) minutes. Intraoperative blood loss was 100 (50, 200) ml. Two patients were converted to open hepatectomy. Clavien-Dindo grade I postoperative complications occurred in 20 patients (32.3%), with grade Ⅱ in 1 patient (1.6%) and grade Ⅲb in another patient (1.6%). The learning curve reached its highest point on the 20th patient by using the cumulative summation test. The study subjects were then assigned into the growth level group (patient 1-20) and the master level group (patient 21-62). The master level group had a significantly wider spread of patient age [(52.9±11.0) years vs (46.1±11.9) years], decreased operation time [(146.8±55.6) min vs (227.9±66.7) min], shortened drainage tube removal time [4(3, 5) d vs 6(4, 7) d] and decreased postoperative hospital stay [5(5, 7) d vs 6.5(4, 9) d] (all P<0.05) when compared with the growth level group. Conclusion:Left lateral hepatic sectionectomy was safe and feasible, and a single operator went through a learning curve of 20 patients before he/she could master the operation more proficiently.

Objective:To investigate the clinical efficacy of laparoscopic hepatic caudate lobectomy.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 5 patients with hepatic caudate lobe tumor who were admitted to the General Hospital of PLA Northern Theater Command from July 2018 to June 2021 were collected. There were 2 males and 3 females, aged 49(range, 26-55)years. All 5 patients underwent laparoscopic hepatic caudate lobectomy. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using telephone interview or outpatient examination to detect tumor recurrence. The follow-up was up to March 2023. Measurement data with skewed distribution were represented as M(range) and count data were described as absolute numbers. Results:(1) Intraoperative situations. All 5 patients underwent laparoscopic hepatic caudate lobectomy with the left approach, including 3 cases receiving laparoscopic partial resection of hepatic caudate lobe, 1 case receiving laparoscopic partial resection of hepatic caudate lobe+left lateral lobectomy and 1 case receiving laparoscopic partial resection of hepatic caudate lobe+cholecystectomy. Intraoperative hilar occlusion was performed in 3 patients. The operation time and volume of intraoperative blood loss of 5 patients was 240(range, 180-370)minutes and150(range, 100-200)mL, respectively. (2) Postoperative situations. On the first day after surgery, the levels of albumin, alanine aminotransferase, and aspartate aminotransferase in 5 patients was 32.9(range, 29.2-40.3)g/L, 104.09(range, 57.11-1 018.67)U/L, and 67.13(range, 58.00-852.66)U/L, respectively. Three of 5 patients showed no significant changes in prothrombin time (PT) on the first day after surgery, while two patients did not undergo PT test. On the third day after surgery, the visual analogue score of 5 patients was mild pain. Among the 5 patients, 1 case had anal exhaust on the postoperative 1st day, and 4 cases had anal exhaust on the postoperative 2nd day. The time to drainage tube removal for 5 patients was 6(range, 4-10)days. There was no postoperative complication such as bleeding, infection, bile leakage or liver failure in 5 patients. Results of postoperative histopathological examination showed that 2 cases with adenoma, 2 cases with cavernous hemangioma and 1 case with smooth myolipoma. The duration of postoperative hospital stay of 5 patients was 6(range, 5-11)days. (3) Follow-up. All 5 patients were followed up for 22 (range, 19-51)months, and there was no tumor recurrence.Conclusion:It is safe and feasible to selectively carry out laparoscopic hepatic caudate lobectomy by strictly gras-ping the indications.
