ABSTRACT
Objective:To investigate the perioperative efficacy of robot surgical system assisted anatomic and non-anatomic hepatectomy.Methods:The propensity score matching and retrospective cohort study was conducted. The clinical data of 103 patients who underwent robot surgical system assisted hepatectomy in Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine from March 2016 to December 2021 were collected. There were 54 males and 49 females, aged 56(range, 44?64)years. Of the 103 patients, 55 cases undergoing robot surgical system assisted anatomic hepatectomy were divided into the anatomic group, and 48 cases undergoing robot surgical system assisted non-anatomic hepatectomy were divided into the non-anatomic group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative conditions; (3) perioperative complications. Propensity score matching was done by the 1:1 nearest neighbor matching method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were expressed as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the rank sum test. Results:(1) Propensity score matching and compari-son of general data of patients between the two groups after matching. Of the 103 patients, 94 cases were successfully matched, including 47 cases in the anatomic group and 47 cases in the non-anatomic group. The elimination of preoperative body mass index, preoperative platelet and preoperative albumin confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative conditions. After propensity score matching, the operation time and volume of intraoperative blood loss were 175(range, 120?240)minutes and 50(range, 50?100)mL in patients of the anatomic group, versus 155(range, 105?190)minutes and 100(range, 50?200)mL in patients of the non-anatomic group, showing significant differences in the above indicators between the two groups ( Z=1.97, 2.49, P<0.05). (3) Perioperative complications. After propensity score matching, cases with pleural fluid and/or ascites, case with biliary fistula, case with thrombosis, case with peritoneal infection, case with incision infection were 11, 1, 2, 4, 1 in patients of the anatomic group, versus 12, 0, 4, 1, 0 in patients of the non-anatomic group, showing no significant difference in the above indicators between the two groups ( P>0.05). Cases with complications classified as grade Ⅰ, grade Ⅱ, grade Ⅲ, grade Ⅳ of the Clavien-Dindo classification were 33, 14, 0, 0 in patients of the anatomic group, versus 28, 14, 3, 2 in patients of the non-anatomic group, showing no significant difference in the above indicators between the two groups ( Z=?1.38, P>0.05). Conclusions:Robotic surgical system assisted anatomic and non-anatomic hepatectomy are safe and feasible for clinical application. Compared with robot surgical system assisted non-anatomic hepatectomy, patients under-going robot surgical system assisted anatomic hepatectomy have long operation time and less volume of intraoperative blood loss.

OBJECTIVE:To study the effect of Shui medicine Asarum insigne polysaccharide on glycolipid metabolism,renal function and oxidative stress in rats with experimental type 2 diabetes,and provide reference for its development and use. METH-ODS:60 SD rats were randomly divided into normal control group,model control group,positive control group (Irbesartan tab-lets,0.02 g/kg) and A. insigne polysaccharide low-dose,medium-dose,high-dose groups (calculated by crude drug as 2,4,8 g/kg),10 in each group. Except for normal control group,rats in other groups were intraperitoneally injected streptozotocin 75 mg/(kg·d)to induce model with diabetes. After modeling,rats in each administration group were intraperitoneally injected relevant medicines,and rats in normal control group and model control group were intragastrically administrated 5% carboxymet hylcellu-lose sodium solution,twice a day,for 42 d. After administration,UV spectrophotometer was used to detect the glycogen content in liver tissue. Automatic biochemical analyzer was used to detect 24 h urine output,24 h urinary protein content of rats,levels of tri-glyceride (TG),cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C), creatinine (Cr),urea nitrogen (BUN) in serum,and levels of superoxide dismutase (SOD),glutathione peroxidase (GSH-Px), catalase(CAT),superoxide dismutase(ROS),malondialdehyde(MDA)in kidney tissue. RESULTS:Compared with normal con-trol group,glycogen content in liver tissue of rats in model control group was decreased(P<0.05);24 h urine output and 24 h uri-nary protein content were increased(P<0.05);levels of TG,TC,LDL-C in serum were increased(P<0.05),and HDL-C level was decreased (P<0.05);levels of SOD,CAT,GSH-Px in kidney tissue were decreased (P<0.05),and levels of ROS,MDA were increased(P<0.05). Compared with model group,except that there were no significant differences in the improvement of uri-nary protein content,HDL-C level in serum,24 h urine out-put in A. insigne polysaccharide low-dose group,above-men-tioned indexes in each administration group were obviously im-proved (P<0.05). CONCLUSIONS:A. insigne polysaccha-ride can regulate lipid metabolic disorders,and improve renal function and antioxidant capacity of rats.
