Objective:To investigate the clinical value of continuous Bougie tube use in symmetrical three-port laparoscopic sleeve gastrectomy (LSG).Methods:The retrospective cohort study was conducted. The clinical data of 105 patients who underwent symmetrical three-port LSG at The First Hospital of Shanxi Medical University from October 2021 to October 2024 were collected. There were 57 males and 48 females, aged 27(range, 19-59)years. Of the 105 patients, 52 cases with continuous Bougie tube use during the surgery were divided into continuous group, while 53 cases with intermittent Bougie tube use were divided into intermittent group. Observation indicators: (1) surgical situations; (2) complications. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of measurement data with skewed distribution between groups was conducted using the Mann-Whitney U test. Comparison of count data between groups was conducted using the chi-square test. Results:(1) Surgical situations. All 105 patients underwent symmetrical three-port LSG. The operation time was (57±4)minutes versus (76±4)minutes for the continuous group and the intermittent group, volume of intraoperative blood loss was (26±6)mL versus (59±9)mL, time to first out-of-bed activities was (218±8)minutes versus (299±9)minutes, time to first anal exhaust was (19.6±2.9)hours versus (25.8±2.8)hours, visual analogue scale score for pain at 6 hours postoperatively was 2.3±1.0 versus 4.7±1.0, and duration of postoperative hospital stay was (1.5±0.6)days versus (3.1±0.9)days for the two groups, respectively. There were significant differences in the above indicators between the two groups( t=26.92, 22.31, 48.91, 11.15, 13.25, 10.21, P<0.05). (2) Complications. No severe postopera-tive complication occurred in any of the 105 patients. There were 26 cases and 38 cases with nausea and vomiting at 2 hours postoperatively, showing a significant difference between them ( χ2=5.19, P<0.05). Conclusion:Compared to intermittent Bougie tube use, continuous Bougie tube use during symmetrical three-port LSG can significantly shorten operation time and duration of postoperative hospital stay, reduce intraoperative bleeding and postoperative pain, accelerate recovery of patients, and lower the incidence of complications.

OBJECTIVE： To systematically evaluate the efficacy and safety of thalidomide combined with conventional chemotherapy in the treatment of advanced gastric cancer， and to provide evidence-based reference for clinical drug use. METHODS： Retrieved from PubMed， Embase， Cochrane library， CNKI， Wanfang database and VIP， RCTs about thalidomide combined with conventional chemotherapy （observation group） vs. conventional chemotherapy （control group） in the treatment of advanced gastric cancer were collected. After data extraction and quality evaluation of included literatures with Cochrane system evaluator manual 5.0 risk evaluation tool， Meta-analysis was conducted by using Rev Man 5.3 statistical software. The evidence qualities of outcome indexes were evaluated by using Grade evidence quality classification system. RESULTS： A total of 13 studies were included， involving 761 patients. Results of Meta-analysis showed that the total response rate [OR＝1.72， 95％CI（1.29，2.31），P＝0.000 2]， complete remission rate [OR＝1.90，95％CI（1.05，3.44），P＝0.03]， disease control rate [OR＝2.66， 95％CI（1.92，3.68），P＜0.001]， improvement rate of survival quality [OR＝3.09， 95％CI（1.82，5.24），P＜0.001] and the incidence of constipation [OR＝2.64， 95％CI（1.74，4.01），P＜0.001] of observation group were significantly higher than those of control group， while disease progression rate [OR＝0.39， 95％CI （0.28，0.54）， P＜0.001] and the incidence of nausea and vomiting [OR＝0.32， 95％CI（0.18，0.56）， P＜0.001] of observation group were significantly lower than those of control group. Results of quality evaluation of Grade evidence showed that total response rate， complete remission rate， the incidence of leucopenia， thrombocytopenia， hemoglobin reduction and liver dysfunction were recommended for advanced evidence. Disease control was recommended for moderate-level evidence. The incidence of disease progression， peripheral neuritis， nausea and vomiting， diarrhea， constipation and hand-foot syndrome were recommended for low-level evidence. Improvement rate of survival was recommended for very low-level evidence. CONCLUSIONS： Thalidomide combined with conventional chemotherapy show significant therapeutic efficacy for advanced gastric cancer， can improve the quality of life but increase the risk of constipation.

In recent years,with the rapid development of minimally invasive surgery,some scholars have advocated laparoscopic surgery as a standard surgical procedure.Because of the physiological position of rectum and the limitations of pelvic space,the robot's fine operation and other advantages are very suitable for radical rectal cancer surgery.Although robot-assisted rectal cancer surgery is highly regarded by many scholars,there are still a few medical centers with Da Vinci robots at home and abroad.At this stage,the research on Da Vinci robotic surgery for rectal cancer is still in the exploratory stage.This article reviews the latest progress of Da Vinci robotic-assisted rectal cancer surgery.

Objective To explore the clinic application value of ultrasonography examination of optic nerve sheath diameter(ONSD) in brain injury.Methods From July 2008-June 2011,90 cases of brain injured patients were chosen as experimental group including light (A group),medium (B group),and heavy (C group) brain injured patients according to the admission GCS score ;50 cases of conventional physical examination and 90 cases of volunteers 50 in neurosurgical outpatient were chosen as control group.The ONSD of both groups were measured 3 mm behind the globe through orbital using color sonographic with different time after admission.3 times measurements were carried out for every optic nerve sheath.All client's ONSD mean and standard deviation were calculated.In 0.5 h after color dopplar ultrasound examination,lumbar vertebra puncturing measured intracranial pressure in different groups.Results After admission (1d,3 d,7 d,14 d),the ONSD of A group was (4.54 ±0.32)mm,(4.42 ±0.30)mm,(4.44 ±0.32) m,and (4.43 ± 0.25) mm,respectively; The ONSD of B groups was (4.48 ± 0.28) mm,(4.52 ± 0.24) mm,(4.46 ±0.28)mm,and (4.38 ±0.22)mm,respectively; The ONSD of C group was (5.67 ±0.35)mm,(6.36 ± 0.42) mm,(5.65 ± 0.23) mm,and (4.76 ± 0.35) mm,respectively.After admission (1 d,3 d,7 d,14 d),the intracranial pressure (IP) of A group was (82 ± 11) mmH2O,(79 ± 12) mmH2O,(90 ±15) mmH2O,and (86 ± 14) mmH2O,respectively; The IP of B group was (78 ± 15) mmH2O,(85 ± 10)mmH2O,(78 ± 16) mmH2O,(80 ± 11) mmH2O,The IP of C group was (225 ± 26) mmH2 O,(288 ± 23)mmH2O,(256 ± 23) mmH2O,(122 ± 18) mmH2O,respectively.Group D had the ONSD average of (4.58± 0.41)mm and IP of (88 ± 10)mmH2O after eyeball 3-mm place.No difference was found between A and B,A and D,or B and D (P＞0.05) ; A difference was found between A and C,B and C,or D and C (t =12.24～24.67,P＜0.01).Conclusions The ONSD and IP in light medium brain injured patients had no change.In patients with severe brain injury,IP changed with the time after injury,the ONSD increased with the IP,the ultrasonography examination of ONSD with the important value in the diagnosis and treatment can respond the IP increase,which is a non-invasion,convenient,fast,and feasible method for evaluation of cranial high pressure.

Objectives To probe into electron beam computed tomography (EBCT) angiography and 3-D reconstruction of coronary artery bypass grafts (CABG) and to evaluate the clinical application of EBCT angiography and 3-D reconstruction of CABG.Methods EBCT angiography with 3-D reconstruction was achieved in 150 patients (142 men and 8 women, mean age, 57±8 years) with 399 grafts including 100 internal mammary artery grafts (IMG), 296 saphenous vein grafts(SVG) and 3 radial artery grafts (RAG) respectively. The time from bypass surgery to EBCT scanning ranged from 7 days to 120 months, averaging 15±28 months. Enhanced single slice mode (SSM) and flow studies were performed in all patients. The results of 3-D reconstruction of CABG were compared with bypass operation records and with coronary arteriograms (7 patients). Results 150 patients underwent successfully EBCT angiography and CABG 3-D reconstruction. According to 3-D reconstruction of the coronary bypass grafts with flow studies, 318 of 399 coronary bypass grafts were patent including IMG patency in 87/100 (87%), SVG in 228/296 (77%) and RAG in 3/3 (100/100). The overall patent rate was 79.7%. In 7 patients with 12 coronary bypass grafts , EBCT studies showed graft patency (7 grafts) and occlusion (5), which were confirmed by conventional graft angiography. Conclusions EBCT angiography with 3-D reconstruction is effective in providing the entire anatomic structure of coronary bypass grafts and evaluating coronary bypass graft patency. EBCT flow study can provide quantitative data for evaluating coronary bypass graft patency and for supplemental diagnosis of CABG 3-D reconstruction. EBCT angiography is a noninvasive technique that could replace conventional coronary arteriography for follow-up survey of coronary bypass surgery in future.
