ABSTRACT
Objective:To compare the cost-effectiveness between open surgery and minimally invasive rotational surgery in patients with benign breast tumor, and to provide a theoretical support for the choice of surgical approach.Methods:The clinical data of 1 389 benign breast tumor patients underwent surgery from January 2017 to January 2020 in Beijing Friendship Hospital, Capital Medical University were retrospectively analyzed. Among them, 374 patients were treated with open surgery (open group), and 1 015 patients were treated with minimally invasive rotational surgery (minimally invasive group). The surgery-related and cost-effectiveness analysis indexes were compared between two groups.Results:The operation time, incidence of hematoma/subcutaneous bruising and cosmetic result satisfactory rate in minimally invasive group were significantly higher than those in open group: (37.37 ± 6.66) min vs. (34.58 ± 8.95) min, 10.54% (107/1 015) vs. 5.35% (20/374) and 98.72% (1 002/1 015) vs. 95.99% (359/374); while the incision length, length of hospital stay and pain score were significantly less than those in open group: (5.00 ± 0.00) mm vs. (26.55 ± 4.73) mm, (1.03 ± 0.36) d vs. (2.85 ± 1.99) d, (1.76 ± 1.56) scores vs. (2.72 ± 1.27) scores, and there were statistical differences ( P<0.01). The patients were followed up until May 2022. There were no incision infection, recurrence and residual lesions in the two groups. The total cost and cost-effectiveness ratio in minimally invasive group were significantly lower than those in open group: (6 553 ± 1 150) yuan vs. (7 965 ± 3 323) yuan and 71.10 ± 13.61 vs. 88.96 ± 37.48, the benefit score was significantly higher than that in open group: (96.50 ± 3.89) scores vs. (88.92 ± 6.39) scores, and there were statistical differences ( P<0.01). Conclusions:Compared with open surgery, minimally invasive rotational surgery is less costly and more benefits, so minimally invasive surgery should be the preferred surgical procedure for benign breast tumor.
ABSTRACT
Objective:To investigate the application value of esophagogastric anastomosis with double muscle flap plasty in total laparoscopic radical resection of proximal gastric cancer.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 5 patients undergoing radical resection of proximal gastric cancer in Cancer Hospital of China Medical University from January to December 2020 were collected. All 5 cases were male, aged from 57 to 72 years, with a median age of 65 years. All 5 patients underwent total laparoscopic radical resection of proximal gastric cancer combined with esophagogastric anastomosis with double muscle flap plasty. Observation indicators: (1) operative situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect postoperative anastomosis, esophageal reflux, nutritional status, quality of life, tumor recurrence and metastasis of patients up to February 2021. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Operative situations: all 5 patients underwent surgery successfully. The operation time, time of esophagogastric anastomosis with double muscle flap plasty, number of lymph node dissected, volume of intraoperative blood loss, length of surgical incision of 5 patients were (316±41)minutes,(109±11)minutes, 26±4, (48±12)mL, (3.4±0.4)cm, respectively. Results of intraoperative rapid frozen section pathological examination showed negative of esophageal margin. (2) Postoperative situations: the time to postoperative initial flatus, time to postoperative initial food intake, during of postoperative hospital stay, cost of treat-ment of 5 patients were (4.8±1.5)days, (5.8±1.5)days, (11.6±2.1)days and (5.5±0.4)×10 4 yuan, respectively. Results of postoperative pathological examination of 5 patients showed gastric adeno-carcinoma in all 5 patients including 4 cases with moderately and poorly differentiated adeno-carcinoma and 1 case with highly differentiated adenocarcinoma, with the TNM staging of pT1a-3N0-1 M0 stage. Of the 5 patients, 1 case underwent postoperative mild pneumonia and was cured by conservative treatment such as anti-infection and promotion of sputum evacuation. (3) Follow-up: all 5 patients were followed up for 2 to 12 months, with a median follow-up time of 6 months. Of the 5 patients, 4 cases underwent anastomotic patency and 1 case underwent mild anastomotic stenosis who was improved after endoscopic treatment. None of the 5 patients underwent reflux esophagitis. The body mass index, the score of nutritional risk screening 2002, the score of patient-generated subjective global assessment and the score of tumor patient quality of life of 5 patients were 21 kg/m 2(range, 19-27 kg/m 2), 2(range, 1-2), 2(range, 1-3) and 47(range, 42-52), respectively. None of the 5 patients underwent tumor recurrence or metastasis. Conclusion:Esophagogastric anas-tomosis with double muscle flap plasty can be used in total laparoscopic radical resection of proximal gastric cancer which will lead to satisfactory short-term efficacy.

ABSTRACT
Objective To observe the changes of subfoveal choroidal thickness (SFCT) in diabetic patients with non-proliferative diabetic retinopathy (NPDR) and clinically significant macular edema(CSME),and then investigate diabetic SFCT and the relationship of diabetic CT with diabetic retinopathy (DR).Methods The patients were divided into 2 groups according to clinical guidelines of DR in China in 2014,including NPDR CSME + group(21 eyes) and NPDR CSME-group(36 eyes).All patients were underwent best corrected visual acuity (BCVA),intraocular pressure,axial length,slit lamp microscope,indirect ophthalmoscope,EDI-OCT examination,and mean arterial blood pressure measurement.The differences of BCVA,central retinal thickness (CRT) and SFCT between NPDR CSME + group and NPDR CSME-group were studied as well by means of using SPSS 18.0 for data statistics.Results There was no significant difference in gender,age,eye axis and intraocular pressure between NPDR CSME + group and NPDR CSME-group (all P ＞ 0.05).There was significant difference in BCVA between the two groups (P =0.001).The mean SFCT were (328.24 ± 101.92) μm in the NPDR CSME + group and (235.31 ± 66.98) μm in the NPDR CSME-group,and the difference was statistically significant (t =4.156,P=0.000).And plotting changes in CRT against changes in SFCT in patients with CSME revealed a positive correlation(r =0.473,P =0.000).Conclusion SFCT in NPDR CSME + patient is thicker than that in NPDR CSME-patient.And plotting changes in CRT against changes in SFCT in patients with CSME reveals a positive correlation.
ABSTRACT
Objective: To investigate the relationship between blood lipid proifles and intraocular pressure (IOP) in adult subjects. Methods: A total of 1660 adult subjects received regular physical examination in our hospital from 2015-01 to 2015-09 were enrolled. The subjects were divided into 2 groups: Hyperlipidemia group,n=356 and Non-hyperlipidemia group,n=1304. Systolic, diastolic blood pressure (SBP), (DBP), IOP and serum levels of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A1(ApoA1) and apolipoprotein B (ApoB) levels were measured in all subjects. SPSS19.0 software was used to study the relationship between blood lipid proifles and IOP by univariate and multivariate liner regression analysis respectively. Results: Univariate regression analysis revealed that IOP was positively related to SBP, DBP, TC, TG, LDL-C and ApoB, all P<0.05, while negatively related to HDL-C,P=0.028. Multivariate regression analysis indicated that with adjusted age, SBP and DBP, IOP was positively related to TC, TG, LDL-C, ApoA1 and ApoB, while negatively related to HDL-C, allP<0.05. ApoB level in either Hyperlipidemia group or Non-hyperlipidemia group was signiifcantly related to IOP in both male and female genders,P<0.05. Conclusion: ApoB level was most obviously related to IOP and it might be used as a predictor for IOP elevation in clinical research, while its validity should be further studied.
