RÉSUMÉ

Objective:To investigate the influene of sarcopenia on quality of life in patients with adenocarcinoma of gastroesophageal junction (AEG).Methods:The retrospective cohort study was conducted. The clinicopathological data of 109 patients with AEG who were admitted to Henan Provincial People′s Hospital from January 2019 to December 2022 were collected. There were 63 males and 46 females, aged (63±11)years. All patients underwent 3D laparoscopic assisted radical total gastrectomy+D 2 lymph node dissection. The skeletal muscle content of patient was obtained within 3 days before surgery by using a multi-frequency bioelectrical impedance human body composition analyzer. Observation indicators: (1) clinical characteristics of patients with sarco-penia and non sarcopenia; (2) intraoperative and postoperative conditions in patients with sarco-penia and non sarcopenia; (3) analysis of serious postoperative complications in patients with AEG; (4) preoperative and postoperative quality of life score in patients with sarcopenia and non sarco-penia. 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 represented as M( Q1, Q3), 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. Comparison of ordinal data was conducted using the Mann-Whitney U non-parameter rank sum test. Repeated measurement data were analyzed using the repeated ANOVA, and their variances were tested using a spherical test. Univariate analysis was conducted using the Logistic regression model, and multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Clinical characteristics of patients with sarcopenia and non sarcopenia. Of 109 patients with AEG, there were 42 cases with sarcopenia and 67 cases with non sarcopenia. The body mass index (BMI), forced expiratory volume in 1 second (FEV1), rate of FEV1/forced vital capacity were (20.3±2.3)kg/m 2, 92%±9%, 79%±11% in patients with sarcopenia, respectively, versus (24.4±2.7)kg/m 2, 97%±9%, 85%±11% in patients with non sarcopenia, showing significant differences in the above indicators between them ( t=8.07, 2.46, 2.77, P<0.05). (2) Intraoperative and postoperative conditions in patients with sarcopenia and non sarco-penia. The volume of intraoperative blood loss, time to postoperative first flatus, duration of post-operative hospital stay, cases with postoperative complications were 208(192, 231)mL, (3.4±0.9)days, (11.4±3.2)days, 26 in patients with sarcopenia, respectively, versus 195(150,215)mL, (2.8±0.7)days, (9.9±1.6)days, 14 in patients with non sarcopenia, showing significant differences in the above indi-cators between them ( Z=-2.14, t=3.25, 3.38, χ2=18.69, P<0.05). (3) Analysis of serious postoperative complications in patients with AEG. Results of multivariate analysis showed that sarcopenia and BMI reduction were independent risk factors influencing serious postoperative complications in patients with AEG ( odds ratio=2.04, 1.98, 95% confidence interval as 1.24-3.36, 1.09-3.60, P<0.05). (4) Pre-operative and postoperative quality of life score in patients with sarcopenia and non sarcopenia. Results of multivariate test in physical function, role function, social function, overall score of patients with sarcopenia and non sarcopenia before surgery, 2 weeks after surgery, 4 weeks after surgery, and 8 weeks after surgery showed that there were significant differences in the temporal effect, intergroup effect and interaction effect of the above indicators between patients with sarcopenia and non sarcopenia ( P<0.05). Results of individual effects showed that there were significant differences in the intergroup effect of the above indicators between patients with sarcopenia and non sarcopenia ( P<0.05). Conclusion:Preoperative sarcopenia increases the risk of severe postoperative complications and reduces the postoperative quality of life in patients with AEG.

Objective:To investigate the effect of CIRc_0000267 on proliferation, migration, invasion and apoptosis of gastric cancer cells in vitro.Methods:Gastric cancer cell lines with circ_0000267 knockdown and miR-661 overexpression were constructed in vitro, and the expressions of circ_0000267, miR-661 and NGAL mRNA in gastric cancer tissues and cells were detected by qRT-PCR. Cell proliferation, migration, invasion and apoptosis were detected by clonogenesis, Transwell chamber and flow cytometry, and related protein expression was detected by Western blot. Online prediction combined with double luciferase assay and RNA pull down assay was used to verify the targeting relationship between circ_0000267, miR-661 and NGAL. Tumogenesis assay in nude mice was used to observe the effect of circ_0000267 knockout on the growth of gastric cancer cells in vivo. Results:Circ_0000267 was highly expressed in gastric cancer tissues and cells. Knockdown circ_0000267 inhibited the proliferation, migration and invasion of gastric cancer cells and promote apoptosis. Circ_0000267 targeted miR-661, and inhibition of miR-661 partially reversed the effect of circ_0000267 on gastric cancer cells. NGAL was the target gene of miR-661, and overexpression of miR-661 regulated the proliferation, migration, invasion and apoptosis of gastric cancer cells by inhibiting NGAL. Knockdown circ_0000267 targeting miR-661 inhibited NGAL expression in gastric cancer cells; Knockdown circ_0000267 inhibited the growth of gastric cancer cells in vivo.Conclusions:Circ_0000267 may regulate the proliferation, migration, invasion and apoptosis of gastric cancer cells and inhibit the growth of tumors in vivo by regulating the expression of miR-661/NGAL.

Objective To explore the clinical effect of three-dimensional (3D) and two-dimensional (2D) laparoscopic radical resection of colorectal cancer.Methods The retrospective cohort study was adopted.The clinical data of 83 patients who underwent laparoscopic radical resection of colorectal cancer at the People's Hospital of Zhengzhou University from March 2014 to November 2015 were collected.Forty-two patients undergoing 2D laparoscopic radical resection of colorectal cancer between March 2014 and December 2014 were allocated into the 2D group and 41 patients undergoing 3D laparoscopic radical resection of colorectal cancer between January 2015 and November 2015 were allocated into the 3D group.All the patients in the 2 groups underwent 2D or 3D laparoscopic radical resection of colorectal cancer based on the principles of lymph node dissection and tumor-free survival.Observation indicators included:(1) surgical situations:operation time,volume of intraoperative blood loss,number of lymph node dissected,(2) postoperative recovery:recovery time of gastrointestinal function,postoperative complications,duration of postoperative hospital stay,hospital expenses,(3) postoperative pathological situations:length of colorectal specimens,distance from tumor to distal incision margin,(4) follow-up.All the patients were followed up to detect postoperative survival,tumor metastasis and recurrence using outpatient examination and telephone interview up to March 2016.Measurement data with normal distribution were presented as x-± s and comparison between groups was analyzed using the t test.Count data were analyzed using chi-square test or Fisher exact probability.Results (1) Surgical situations:all the patients underwent successful laparoscopic radical resection of colorectal cancer,without conversion to open surgery and perioperative death.Operation time,volume of intraoperative blood loss and number of lymph node dissected were (171 ±18) minutes,(112±18)mL,14.0 ± 1.4 in the 2D group and (125 ± 13) minutes,(101 ± 16)mL,14.6 ± 0.9 in the 3D group,respectively,with statistically significant differences between the 2 groups (t =-13.091,-2.962,-3.623,P <0.05).(2) Postoperative recovery:recovery time of gastrointestinal function was (3.0 ± 0.6) days in the 2D group and (3.0 ± 0.6) days in the 3D group,respectively,with no statistically significant difference between the 2 groups (t =3.423,P > 0.05).Incidence of postoperative complications in the 2D and 3D groups was 7.1% (3/42) and 4.9% (2/41),respectively,with no statistically significant difference between the 2 groups (P >0.05).One,1,1 patients in the 2D group were respectively complicated with anastomotic fistula,intra-abdominal hemorrhage and intra-abdominal infection,1 and 1 patients in the 3D group were respectively complicated with anastomotic fistula and intestinal paralysis,and they were improved by symptomatic treatment.Duration of postoperative hospital stay and hospital expenses was (10.0 ±0.8)days,(7.0 ± 1.4) × 104 yuan in the 2D group and (10.0 ±0.6)days,(7.3 ± 1.5) x 104 yuan in the 3D group,respectively,with no statistically significant difference between the 2 groups (t =15.716,0.941,P > 0.05).(3)Postoperative pathological situations:length of colorectal specimens and distance from tumor to distal incision margin were (18 ± 7) cm,(4.7 ± 0.6) cm in the 2D group and (20 ± 8) cm,(4.9 ± 0.7)cm in the 3D group,respectively,with no statistically significant difference between the 2 groups (t =0.742,1.401,P >0.05).(4)Follow-up:of 83 patients,82 were followed up for 5-24 months with a median time of 12 months.During the follow-up,there was no occurrence of tumor-related death and recurrence and metastasis of sites of puncture.Intra-abdominal tumor recurrence,recurrence of anastomotic tumor and tumor distant metastasis were detected in 3,2,1 patients in the 2D group and 2,1,1 patients in the 3D group,with no statistically significant difference between the 2 groups (P > 0.05).Conclusion Compared with 2D laparoscopic radical resection of colorectal cancer,3D laparoscopic radical resection of colorectal cancer is safe and feasible,and it can also reduce intraoperative blood loss and increase the rate of lymph node dissected,with a good short-term outcome.
