Objective To evaluate the role of sarcolemmal ATP-sensitive potassium ( sarcKATP ) channel in sevoflurane-induced maintenance of electrophysiological stability of ventricular myocardium in di-abetic rats. Methods Clean-grade healthy male Sprague-Dawley rats, aged 3 months, weighing 280-320 g, in which diabetes mellitus ( DM) was induced by intraperitoneal streptozotocin 60 mg/kg and confirmed by blood glucose ≥16. 7 mmol/L, were used in this study. Their hearts were excised after anesthesia and retrogradely perfused in a Langendorff apparatus at 4 weeks after establishing the DM model. Twenty-four Langendorff-perfused hearts were divided into 3 groups ( n=8 each) using a random number table method:DM group ( group D) , DM plus sevoflurane group ( group DS) and DM plus sevoflurane plus HMR-1098 group (group DSH). Another 8 Langendorff-perfused hearts of normal rats were selected as control group ( group C) . Hearts were perfused with 37℃ K-H solution via the aorta in each group, 15 min of equilibra-tion later hearts were continuously perfused for 30 min with K-H solution in C and D groups, with K-H solu-tion saturated with 2. 5% sevoflurane in group DS, or with K-H solution saturated with 10 μmol/L HMR-1098 and 2. 5% sevoflurane in group DSH. Monophasic action potential (MAP) duration at 50% and 90%repolarization ( MAPD50 and MAPD90 ) in the endocardium and epicardium of the left ventricular anterior wall were recorded at 15 min of equilibration ( T0 ) and 15 and 30 min of reperfusion ( T1,2 ) , transmural dispersion of repolarization ( TDR) was calculated. S1S2 program-controlled stimulation was performed at the end of perfusion to record the effective refractory period (ERP), ventricular arrhythmia (VA) induced and the longest pacing cycle length ( PCL) of ventricular fibrillation threshold ( VFT) induced. ERP/MAPD90 ratio was calculated. Results Compared with group C, TDR was significantly increased at T0 , ERP/MADP90 ratio was decreased, the incidence of VA induced was increased, and the longest PCL of VFT induced was prolonged in group D ( P<0. 05) . Compared with group D, TDR was significantly decreased at T2 in group DS (P<0. 05), and ERP/MADP90 ratio was significantly increased, the incidence of VA in-duced was decreased, and the longest PCL of VFT induced was shortened in DS and DSH groups ( P<0. 05). TDR was significantly smaller at T2 in group DSH than in group DS (P<0. 05). Conclusion sarcKATP channel is involved in sevoflurane-induced maintenance of electrophysiological stability of ventricu-lar myocardium in diabetic rats.

Objective To evaluate the effect of sevoflurane on the electrophysiological stability of i-solated rat hearts subjected to hypothermic perfusion. Methods Clean-grade healthy adult male Sprague-Dawley rats, weighing 280-360 g, were heparinized and anesthetized with pentobarbital sodium. Their hearts were excised and perfused in a Langendorff apparatus with K-H solution saturated with 95% O2-5%CO2 at 37℃. Twenty-four Langendorff-perfused hearts were divided into 4 groups ( n=6 each) using a ran-dom number table method: control group ( C group ) , sevoflurane group ( S group ) , 32 ℃ hypothermia group ( H group) and 32℃ hypothermia plus sevoflurane group ( HS group) . After 15 min of equilibration, the isolated hearts were continuously perfused for 30 min with K-H solution at 37℃, with K-H solution con-taining 2. 3% sevoflurane at 37 ℃, with K-H solution at 32 ℃, and with K-H solution containing 2. 3%sevoflurane at 32℃ in C, S, H and HS groups, respectively. Heart rate and monophasic action potential in three layers of the left ventricular anterior wall were recorded at 15 min of equilibration ( T0 ) and 30 of con-tinuous perfusion ( T2 ) , the transmural dispersion of repolarization ( TDR) were calculated, and the occur-rence of arrhythmia was observed. Results Compared with C and S groups, the heart rate was significantly decreased and TDR was enlarged at T1 , and the incidence of arrhythmia was increased in H and HS groups ( P<0. 05) . Compared with H group, TDR was significantly reduced at T1 , and the incidence of arrhythmia was decreased in HS group ( P<0. 05) . Conclusion Sevoflurane can improve the electrophysiological in-stability of isolated rat hearts subjected to hypothermic perfusion, and thus decrease the development of ar-rhythmia.

Objective:To investigate the clinical value of fascia orientated laparoscopic lateral lymph node dissection (LLND) in radical excision for advanced low rectal cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 100 patients with advanced low rectal cancer who were admitted to Peking University First Hospital from January 2013 to August 2021 were collected. There were 69 males and 31 females, aged 58(range, 32?85)years. Patients underwent laparoscopic total mesorectal excision and fascia oriented LLND. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) results of histopathological exa-mination; (4) follow-up. Follow-up was conducted by telephone interview, outpatient examination and medical records review to detect survival, disease progression, tumor recurrence and metastasis of patients up to August 2021. Survival time was from the surgery date to death or the last follow-up time of patients. Measurement data were represented as M(range). Count data were represented as absolute numbers. Kaplan-Meier method was used to draw survival curves and calculate survival rates. Results:(1) Surgical situations. Of the 100 patients, 44 cases underwent neoadjuvant therapy and 56 cases didn′t receive preoperative therapy. Of the 100 patients with laparoscopic radical excision for advanced low rectal cancer, 60 cases underwent low anterior resection of rectal cancer including 49 cases with unilateral LLND and 11 cases with bilateral LLND,20 cases underwent abdomin-operineal resection for rectal cancer including 16 cases with unilateral LLND and 4 cases with bilateral LLND, 12 cases underwent total pelvic exenteration including 6 cases with unilateral LLND and 6 cases with bilateral LLND, 5 cases underwent Hartmann surgery including 3 cases with unilateral LLND and 2 cases with bilateral LLND, 3 cases underwent posterior pelvic exenteration including 2 cases with unilateral LLND and 1 case with bilateral LLND. The operation time and volume of intraoperative blood loss were 258(range,200?325)minutes and 100(range, 50?200)mL. There were 19 patients with low anterior resection of rectal cancer and protective ileostomy simultaneously. Three patients encountered intraoperative lymph node invasion of the obturator nerve, causing injury of the nerve at dissection. Of the 100 patients, 12 cases with total pelvic exenteration were dissected the ureterohypogastric nerve fascia and 88 cases were preserved the complete ureterohypogastric nerve fascia. (2) Postoperative situations. There was no perioperative death in the 100 patients. The time to postoperative catheter removal and duration of hospital stay of the 100 patients were 4(range, 3?7)days and 11(range, 9?15)days, respectively. There were 26 cases with postoperative complications. (3) Results of histopathological examination. The maximum tumor diameter was 4.5(range, 3.8?5.9)cm. There were 21 patients with mass type of tumor pross and 79 cases with ulcerative type. There were 82 cases with high and moderate differentiation of tumor differentiation degree, 18 cases with low differentiation and undifferentiated adenocarcinoma (signet ring cell carcinoma). There were 14 cases in TNM stage Ⅰ, 38 cases in TNM stage Ⅱ, 48 cases in TNM stage Ⅲ. There were 16 cases in stage T0?2 and 84 cases in stage T3?4. There were 52 cases in stage N0 and 48 cases in stage N1?2. The total number of lymph node dissected was 23(range, 18?27)per person and the total number of unilateral LLND was 5(range, 3?9)per person. There were 36 of 100 patients with positive lateral lymph nodes, including 14 cases with neoadjuvant therapy. (4) Follow-up. Of the 100 patients, 97 cases were followed up for 21(range, 1?69)months. The 2-year overall survival rate was 81.6% and 2-year disease progression free survival rate was 70.6%. During the follow-up, 4 of 97 patients had presacral tumor recurrence and 1 case had tumor recurrence in the LLND region. There were 11 cases with liver metastasis, 5 cases with bone metastasis, 2 cases with the contralateral lymph node metastasis of unilateral LLND, 2 cases with paraaortic lymph node metastasis, 2 cases with transcoelomic spread. Of the 97 patients who were followed up, 76 cases survived with free disease, 4 cases survived with tumor, 15 cases died of tumor and 2 cases died of other diseases.Conclusion:The fascia orientated laparoscopic LLND is safe and feasible in radical excision for advanced low rectal cancer.
