ABSTRACT

BACKGROUND@#Ventricular remodeling after acute anterior wall ST-segment elevation myocardial infarction (AAMI) is an important factor in occurrence of heart failure which additionally results in poor prognosis. Therefore, the treatment of ventricular remodeling needs to be further optimized. Compound Danshen Dripping Pills (CDDP), a traditional Chinese medicine, exerts a protective effect on microcirculatory disturbance caused by ischemia-reperfusion injury and attenuates ventricular remodeling after myocardial infarction.@*OBJECTIVE@#This study is designed to evaluate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function after AAMI on a larger scale.@*METHODS@#This study is a multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical trial. The total of 268 patients with AAMI after primary percutaneous coronary intervention (pPCI) will be randomly assigned 1:1 to the CDDP group (n=134) and control group (n=134) with a follow-up of 48 weeks. Both groups will be treated with standard therapy of ST-segment elevation myocardial infarction (STEMI), with the CDDP group administrating 20 tablets of CDDP before pPCI and 10 tablets 3 times daily after pPCI, and the control group treated with a placebo simultaneously. The primary endpoint is 48-week echocardiographic outcomes including left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume index (LVEDVI), and left ventricular end-systolic volume index (LVESVI). The secondary endpoint includes the change in N terminal pro-B-type natriuretic peptide (NT-proBNP) level, arrhythmias, and cardiovascular events (death, cardiac arrest, or cardiopulmonary resuscitation, rehospitalization due to heart failure or angina pectoris, deterioration of cardiac function, and stroke). Investigators and patients are both blinded to the allocated treatment.@*DISCUSSION@#This prospective study will investigate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function in patients undergoing pPCI for a first AAMI. Patients in the CDDP group will be compared with those in the control group. If certified to be effective, CDDP treatment in AAMI will probably be advised on a larger scale.

ABSTRACT

@#Objective    To summarize the experience of robot-assisted lung basal segmentectomy, and analyze the clinical application value of intersegmental tunneling and pulmonary ligament approach for S9 and/or S10 segmentectomy. Methods    The clinical data of 78 patients who underwent robotic lung basal segmentectomy in our hospital between January 2020 to May 2022 were retrospectively reviewed. There were 32 males and 46 females with a median age of 50 (33-72) years. The patients who underwent S9 and/or S10 segmentectomy were divided into a single-direction group (pulmonary ligament approach, n=19) and a bi-direction group (intersegmental tunneling, n=19) according to different approaches, and the perioperative outcomes between the two groups were compared. Results    All patients successfully completed the operation, without conversion to thoracotomy and lobectomy, serious complications, or perioperative death. The median operation time was 100 (40-185) min, the blood loss was 50 (10-210) mL, and the median number of dissected lymph nodes was 3 (1-14). There were 4 (5.1%) patients with postoperative air leakage, and 4 (5.1%) patients with hydropneumothorax. No patient showed localized atelectasis or lung congestion at 6 months after the operation. Further analysis showed that there was no significant difference in the operation time, blood loss, thoracic drainage time, complications or postoperative hospital stay between the single-direction and bi-direction groups (P>0.05). However, the number of dissected lymph nodes of the bi-direction group was more than that of the single-direction group [6 (1-13) vs. 5 (1-9), P=0.040]. Conclusion    The robotic lung basal segmentectomy for pulmonary nodules is safe and effective. The  perioperative results of robotic S9 and/or S10 complex segmentectomy using intersegmental tunneling and pulmonary ligament approach are similar.

ABSTRACT

@#Objective    To explore the clinical efficacy of thoracoscopy-assisted modified Nuss procedure for pectus excavatum (PE) in children. Methods    The clinical data of patients with PE who underwent thoracoscopy-assisted modified Nuss procedure from October 2013 to October 2020 in Daping Hospital were retrospectively analyzed. Results    A total of 86 patients were collected, including 79 males and 7 females with a mean age of 14.03±3.36 years. The operations were performed successfully in all patients without intraoperative cardiac vascular injury or perioperative death. The mean operation time was 87.30±33.45 min, bleeding volume was 19.94±14.60 mL, and the postoperative hospitalization stay time was 6.89±2.59 d. Early postoperative complications included 2 patients of pneumothorax, 2 patients of wound fat liquefaction and infection, 2 patients of bar flipping and displacement. One patient had bar displacement 1 year after the surgery. The total complication rate was 8.14%. All patients were followed up for 3-42 months. The bars were taken out about 36 months after the surgery. According to the evaluation criteria of orthopedic effect, 68 (79.07%) patients were excellent, 10 (11.63%) patients were good, 5 (5.81%) patients were moderate and 3 (3.49%) patients were poor. Conclusion    Minimally invasive and individualized shaping via the Nuss procedure for PE children is safe and convenient, with satisfied effect. It is worthy of popularization in the clinic.

ABSTRACT

@#Objective     To compare the perioperative outcomes of atypical segmentectomy between robotic-assisted thoracoscopic surgery (RATS) and conventional video-assisted thoracoscopic surgery (VATS) in early-stage non-small cell lung cancer (NSCLC). Methods    The data of patients who underwent minimally invasive anatomic atypical segmentectomy in our hospital from October 2016 to December 2021 were collected. These patients were divided into a RATS group and a VATS group according to the operation method. Propensity score (PS) matching was used to select patients with close clinical baseline characteristics, and the perioperative results of the two groups were compared. Results    A total of 1 048 patients were enrolled, including 320 males and 728 females, with a mean age of 53.51±11.13 years. There were 277 patients in the RATS group and 771 patients in the VATS group. After 1∶1 PS matching, 277 pairs were selected. Both groups were well balanced for age, sex, smoking history, body mass index, Charlson comorbidity index, pulmonary function, tumor size, tumor location, and histological type. All patients were R0 resection, and there were no deaths within 30 days after surgery. The RATS group had shorter operative time [85 (75, 105) min vs. 115 (95, 140) min, P<0.001] and less blood loss [50 (30, 100) mL vs. 60 (50, 100) mL, P=0.001]. There were no statistical differences between the two groups in lymph node resection, conversion to thoracotomy, thoracic drainage time, total amount of thoracic drainage or postoperative complications (P>0.05). Conclusion    Both RATS and VATS atypical segment-ectomies are safe and feasible for early-stage NSCLC. RATS can effectively shorten the operative time, and reduce blood loss.

ABSTRACT

Objective:To explore the feasibility and application value of case-based learning (CBL) combined with clinical pathway in thoracic surgery practice teaching.Methods:A total of 30 clinical undergraduate students who practiced from January 2018 to August 2018 were selected and randomly divided into the traditional group and the research group. The traditional group used traditional teaching mode, while the research group adopted the CBL combined with clinical pathway teaching. The scores of theoretical examination and practice skills assessment and the case analysis ability of the two groups were compared at the time of department. In addition, the evaluation of the teaching effect of the two groups of teachers and students was observed through anonymous questionnaires. SPSS 21.0 was used for t-test and Chi-square test. Results:The scores of the students in the research group were better than those in the traditional group, including score of theoretical examination [(88.20±4.02) vs. (80.76±4.62), P<0.001], score of practice skills assessment [(90.80±2.16) vs. (84.80±3.07), P<0.001] and case analysis ability [(89.80±3.34) vs. (81.86±4.31), P<0.001]. The differences were statistically significant. At the same time, the questionnaire showed that the research group was superior to the traditional group in improving students' learning interest, clinical skills, case analysis ability, clinical communication ability, theoretical knowledge understanding and clinical thinking ability, with a statistically significant difference ( P<0.05). While the two groups had no statistically significant difference in students' satisfaction with teachers ( P=0.083). Conclusion:The CBL method combined with clinical pathway teaching method can improve the teaching effect of thoracic surgery practice, which is worth popularizing.

ABSTRACT

Objective:To investigate the relationship between telomere length of bone marrow mononuclear cells and prognosis of patients with acute myeloid leukemia (AML) who received allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:Telomere length of bone marrow mononuclear cells before transplantation, after transplantation and before donor mobilization as well as information related to follow-up of 33 AML patients who received allo-HSCT in the Affiliated Hospital of Guizhou Medical University between June 2020 and June 2021 were retrospectively analyzed. Telomere length was detected by using telomeric terminal restriction fragment (TRF) method. Telomere length was compared among patients with different prognoses. The recurrence within 1 year was treated as the gold standard and receiver operating characteristic (ROC) curve was used to analyze the effect of telomere length before transplantation or before donor mobilization in the judgement of the recurrence within 1 year after transplantation. The patients were stratified according to the optimal threshold value of telomere length for patients or donors, and Kaplan-Meier method was used to compare the progression-free survival (PFS) of patients with different stratification, and log-rank test was performed.Results:The median age of 33 patients was 34 years (14-61 years), and there were 17 males and 16 females; 31 patients were initially diagnosed with AML, 1 patient transferred from myelodysplastic syndrome (MDS) to AML, and 1 patient transferred from chronic granulocytic leukemia (CML) to AML; 14 received identical sibling transplantation and 19 received haploidentical sibling transplantation. The median age of the donors was 30 years (20-65 years), including 24 males and 9 females. Telomere length of bone marrow mononuclear cells before mobilization in 33 donors was longer than that in patients before transplantation (33 cases) and at +30 d after transplantation (31 cases) [(6.67±0.31) kb, (6.40±0.33) kb, (6.48±0.33) kb, respectively; all P < 0.05], and the difference between patients before and at +30 d after transplantation was not statistically significant ( t = 0.89, P = 0.378), and the telomere length of bone marrow mononuclear cells in 11 patients +180 d after transplantation was (6.66±0.18) kb. The incidence of acute graft-versus-host disease (aGVHD) after transplantation was 45.5% (15/33), the incidence of infection with clear imaging and pathogenic basis was 39.4% (13/33), the mortality rate within 1 year after transplantation was 3.0% (1/33), and the recurrence rate within 1 year after transplantation was 15.2% (5/33). There were no statistically significant differences in telomere length of donor pre-mobilization bone marrow mononuclear cells between the groups with and without aGVHD and between the infected and non-infected groups (all P > 0.05).Compared with patients who had not relapsed within 1 year after transplantation, telomere length of donor pre-mobilization bone marrow mononuclear cells was shorter in patients who relapsed within 1 year after transplantation [(6.39±0.19) kb vs. (6.72±0.30) kb, t = -3.23, P = 0.011], telomere length was longer in patients before transplantation [(6.75±0.16) kb vs. (6.35±0.36) kb, t = 4.17, P = 0.001]. ROC curve analysis showed that the optimal threshold values for telomere length of pre-transplantation and donor pre-mobilization bone marrow mononuclear cells were 6.48 and 6.42 kb, respectively for patients who relapsed within 1 year after transplantation. PFS in patients with pre-transplantation bone marrow mononuclear cells telomere length < 6.48 kb was better than that in patients with telomere length ≥ 6.48 kb ( P = 0.003); PFS in patients with pre-mobilization bone marrow mononuclear cells telomere length>6.42 kb was better than that in patients with telomere length ≤ 6.42 kb ( P < 0.001). Conclusions:In allo-HSCT for AML, patients have an increased risk of relapse within 1 year after transplantation when their pre-transplantation bone marrow mononuclear cells telomere length is long and the donor bone marrow mononuclear cells telomere length is short.

ABSTRACT

Objective To understand the characteristics and developmental differences between cerebral organoids in vitro and normal cerebral cortices in vivo. Methods 1. Grouping: cerebral cortices in vivo group and cultured cerebral organoids in vitro group. 2. Sample collection: cortical tissues were collected from Kunming mouse embryos at embryonic day 7.5(E7.5), E9.5, E11.5, E14.5, and postnatal day 3 (P3) or P7. Three specimens were taken from each group. Meanwhile, cerebral organoids were cultured with mouse induced pluripotent stem cells (iPSCs), and samples at different culture time point were collected, and more than 3 samples were collected at each time point. 3. Detection method: the distribution of different types of cells in each group of specimens was analyzed by immunofluorescent staining. Results While relative similarities between in vivo cerebral cortical development and the cerebral organoids in vitro were observed, including the histogenesis, and the morphological differentiation of nerve cells and glial cells, the lamellar architecture of cerebral cortex in mouse brain was not observed in cerebral organoids. Conclusion The development of cerebral organoids in vitro has some similarity with body's cortical development. Therefore, cerebral organoids can be used to a substitution of cortex and diseases' models, but improvement of the existing technologies is necessary.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy between visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy (VPTED) and traditional percutaneous transforaminal endoscopic discectomy(PTED) in the treatment of lumbar disc herniation.@*METHODS@#The clinical data of 60 patients with lumbar disc herniation admitted from June 2019 to December, 2020 was retrospectively analyzed. There were 38 males and 22 females, aged from 26 to 58 years old with an average of (43.63±8.48) years, 47 cases were on L4,5 segment and 13 cases were on L5S1 segment. Among them, 32 were treated with VPTED (group A) and 28 were treated with traditional PTED (group B). The general conditions of all the patients were recorded, including intraoperative fluoroscopy times, operation time, hospital stay and surgical complications during follow-up. The arthroplasty area ratio was observed by sagittal CT at the middle level of the intervertebral foramen. Visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) score of low back pain, Oswestry disability index (ODI) were used to evaluate the clinical efficacy between two groups.@*RESULTS@#All patients were followed up from 9 to 15 months with an average of (12.10±1.16) months. There was no statistical difference of preoperative general data between two groups. The operation time, fluoroscopy times and hospital stay were (70.47±5.87) min, (13.66±1.34) times and (6.31±0.69) d in group A, and (90.71±7.66) min, (22.82±2.48) times and (6.54±0.92) d in group B. The operation time and intraoperative fluoroscopy times in group A were lower than those in group B(P<0.05). There was no significant difference in hospital stay between two groups (P>0.05). No obvious surgical complications were found during the follow-up in both groups. The arthroplasty area ratio in group A was (29.72±2.84)% and (29.57±2.20)% in group B, respectively, with no significant difference (P>0.05). There was no significant difference in VAS, ODI and JOA score between two groups before operation and at the final follow-up(P>0.05), but the final follow-up was significantly improved(P<0.05).@*CONCLUSION@#The two surgical methods have definite clinical efficacy in the treatment of lumbar disc herniation. Visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy has the advantages of high efficiency and rapidity when establishing the channel, and can significantly reduce the operation time and intraoperative fluoroscopy times.

ABSTRACT

Objective:To investigate characteristics and differences of cerebral glucose metabolism in patients with anti- N-methyl- D-aspartate receptor (NMDAR) encephalitis from the perspective of different trigger factors of antibodies. Methods:A total of 15 patients (8 males, 7 females, age (30.5±17.7) years) with anti-NMDAR encephalitis between January 2016 and January 2019 in Huashan Hospital, Fudan University were recruited retrospectively. All patients underwent resting state cerebral 18F-FDG PET imaging. The characteristics of brain glucose metabolism were analyzed, and the SUV ratio (SUVR) was semi-quantitatively compared with that in 12 healthy subjects (HS; 7 males, 5 females, age (51.5±9.6) years). Independent-sample t test was used to analyze the data. Results:Among 15 patients, 5 patients were viral encephalitis-related anti-NMDAR encephalitis, showing focal decreased metabolism in unilateral temporal lobe or basal ganglia (SUVR: patients: 0.659±0.219; HS: 1.754±0.203; t=-9.58, P<0.001), with increased metabolism in contralateral temporal lobe or basal ganglia (SUVR: patients: 2.275±0.244; HS: 1.960±0.227; t=2.55, P=0.022) in 18F-FDG PET imaging. Six patients were cryptogenic anti-NMDAR encephalitis, showing asymmetric increased metabolism in frontal, temporal, parietal and basal ganglia (SUVR: patients: 2.482±0.395; HS: 1.754±0.203; t=5.23, P<0.001), with decreased metabolism in bilateral occipital lobes. The remaining 4 cases were paraneoplastic origin accompanied by teratoma, showing increased metabolism in bilateral temporal and basal ganglia (SUVR: patient: 2.359±0.181; HS: 1.960±0.227; t=3.16, P=0.007), with mild decreased metabolism in bilateral occipital lobe. Conclusions:The abnormal changes of cerebral glucose metabolism in patients with anti-NMDAR encephalitis can be divided into at least three patterns according to different trigger factors. A comprehensive understanding of these characteristic metabolic changes is helpful for detecting disease, and may provide potential value in indicating different causes.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy of Wen-Luo-Tong Granules (WLT) local administration in the treatment of patients with peripheral neuropathy (PN) induced by chemotherapy or target therapy.@*METHODS@#This study is a randomized, double-blinded, and placebo-controlled trial. Seventy-eight patients with PN induced by chemotherapy or target therapy were enrolled from China-Japan Friendship Hospital between July 2019 and January 2020. They were randomly assigned to WLT (39 cases) and control groups (39 cases) using a block randomization method. The WLT group received WLT (hand and foot bath) plus oral Mecobalamin for 1 week, while the control group received placebo plus oral Mecobalamin. The primary endpoint was PN grade evaluated by the National Cancer Institute-Common Toxicity Criteria for Adverse Events (NCI-CTCAE). The secondary endpoints included quantitative touch-detection threshold, neuropathy symptoms, Quality of Life Questionnaire-Chemotherapy Induced Peripheral Neuropathy (QLQ-CIPN20), and Quality of Life Questionnaire-Core30 (QLQ-C30).@*RESULTS@#After treatment, the PN grade in the WLT group was significantly lower than that in the control group (1.00 ± 0.29 vs. 1.75 ± 0.68, P<0.01). The total effective rate in the WLT group was significantly higher than that in the control group (82.05% vs. 51.28%, P<0.01). Compared with the control group, the touch-detection thresholds at fingertips, neuropathy symptom score, QLQ-CIPN 20 (sensory scale, motor scale, autonomic scale, and sum score), and QLQ-C30 (physical functioning, role functioning, emotional functioning, and global health) in the WLT group significantly improved after treatment (P<0.01 or P<0.05).@*CONCLUSION@#WLT local administration was significantly effective in the treatment of patients with PN induced by chemotherapy or target therapy.

ABSTRACT

Drug use during pregnancy is unavoidable. Therefore, it is vitally important for medical workers to help pregnant women take drugs correctly to reduce the incidence of spontaneous abortion, premature birth, and low birth weight. In our study, drug screening model with induced pluripotent stem cells (iPSCs) was used to find some improper drugs which will result in woman's abortion. With 3D culture in vitro, iPSCs can form embryoid bodies (EBs) and cerebral organoids, which simulated in vitro development of early embryos, from inner cell mass to germ-layer differentiation. In the experiment, EBs were exposed to mifepristone (RU486), and three experimental groups were divided randomly. They were control group (without RU486), low-dose group (L-RU486, 10 μg·mL-1), and high-dose group (H-RU486, 20 μg·mL-1). After mifepristone exposure, EBs were observed at days 5, 8, and 11, including size of EB, cell apoptosis, and differentiation of germ layers, by using inverted optical microscope, TUNEL assay, and immunofluorescent staining. The results showed that through 3D culture, iPSCs could develop into embryoid bodies, neural rosettes, and finally cerebral organoids. After mifepristone exposure, EBs' sizes were decreased (P < 0.01); the levels of cell apoptosis in EBs were increased after mifepristone exposure (P < 0.01); the development of EBs' germ layer was affected. Mifepristone exposure could inhibit the proliferation of embryonic stem cells, reduce the differentiation of ectoderm (P < 0.01) and promote the development of mesoderm (P < 0.05). In conclusion, iPSCs can be used as a screening model for abortion drug, and EBs’ diameter, cell apoptosis, and differentiation changes of the germ layers can serve as criteria of abortion drug screening.

ABSTRACT

OBJECTIVE@#To explore the efficacy of a novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint.@*METHODS@#Retrospective analysis of 13 cases of proximal clavicle fracture with dislocation of sternoclavicular joint treated with sternoclavicular hook-plate from June 2011 to January 2019 in our department. There were 9 males and 4 females, aged 26 to 78 years old, with an average age of (54.08±13.91) years old. All the patients had closed injuries without damage of blood vessels and nerves. The patient's operation time, intraoperative blood loss, hospital stay time, and postoperative complications were recorded. Fracture healing and reduction were evaluated according to X-ray and CT after operation. Constant-Murley score and Rockwood sternoclavicular joint score were used to evaluate limb function at 12 months after operation.@*RESULTS@#All the patients were treated with sternoclavicular hook-plate. The operation time ranged from 50 to 76 min, with a mean of (54.08±13.91) min. The intraoperative blood loss ranged from 20 to 56 ml, with a mean of (46.08±11.15) ml. The hospital stay time ranged from 6 to 14 d, with a mean of (8.31±2.32) d. X-ray and CT examination on the second day after operation showed that all fractures and dislocations were anatomically reduced, and shoulder joint function exercise was performed early. All patients were followed up, and the duration ranged from 12 to 24 months, with a mean of (16.77±4.63) months. The healing time ranged from 9 to 13 d, with a mean of (11.00±1.75) d;and the bone healing time ranged from 3 to 4 months, with a mean of (3.65±0.46) months. There were no complications such as infection, internal fixation failure and nerve injury. At 12 months follow-up, the constant Murley score ranged from 78 to 100, with a mean of 87.83± 11.26; and Rockwood score ranged from 9 to 15, with a mean of 13.70±1.85. Among them, 11 cases were excellent, 1 case was good, and 1 case was general.@*CONCLUSION@#The use of the novel sternoclavicular hook-plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint is an effectively internal fixation with high safety, allowing early functional exercise for patients.

ABSTRACT

Objective::To investigate the distribution status of medicinal plants in the wild areas of Russian Caucasus and Altai, and clarify the types and efficacy information of medicinal plants in the area, so as to dig deep into new resources and new functions of medicinal plants in the countries along the Belt and Road. Method::Medicinal plants in the wild were searched and collected to make waxy specimens, and sent back to the country to extract the total DNA of the leaves of the leaves. Internal Transcribed Spacer(ITS)sequence universal primers were used for Polymerase Chain Reaction (PCR)amplification. The PCR products were sent for the two-way sequencing, and the sequencing results are spliced by software according to National Center for Biotechnology Information(NCBI). The same ITS sequence of the highest similarity species obtained by database BLAST was analyzed by DNAman software to identify the ITS sequence of the species and the ITS sequence of the same species. The MEGA 7 software was used as the phylogenetic tree, and the Kimura-2 parameter genetic distance was used to construct the neighbor joining(NJ) phylogenetic tree by the neighbor-joining method. The confidence of each branch of the development tree was tested by the bootstrap test method. A total of 2 000 cycles were performed, and the results were identified based on the clustering results. On this basis, the key medicinal plants in the Russian Caucasus and Altay wild areas were summarized and analyzed. Result::After BLAST alignment in NCBI database, the ITS sequences of each specimen were clustered with the login sequences on the NCBI database, which were separated from the outer group. The species classification of the specimens to be identified was determined by combining the characteristics of the specimens. A total of 51 plants were identified from the specimens collected in the field, covering 44 genera of 17 families, and 29 plants had clear efficacy records. The National Drug List of the Russian Federation and the Chinese Pharmacopoeia were retrieved to summarize commonly used medicinal plants in China and conclude that 20 kinds of Chinese and Russian common medicinal materials have different medicinal effects in local areas. This study has a reference significance for expanding the scope and clinical experience of traditional Chinese medicines, and provides a basis for strengthened local species conservation, development and utilization of wild medicinal plant resources.

ABSTRACT

Objective:To summarize the experience of robotic and thoracoscopic segmentectomy in Daping Hospital, Army Medical University, and comparison analysis the clinical application value for early-stage lung cancer.Methods:A retrospective cohort study was conducted to continuously enroll 190 patients, 100 who received robotic(33 males and 67 females, median age of 51 years)and 90 who received VATS(34 males and 56 females, median age of 54 years), who underwent segmentectomy between June 2018 and October 2019. Perioperative outcomes(the operation time, intraoperative blood loss, postoperative thoracic drainage volume and time, pain score, complications, postoperative hospital stay and survival and mortality) were compared.Results:All the patients successfully completed the surgery and recovered from hospital, with no perioperative death.The baseline characteristics(sex, age, clinical symptoms, smoking status, underlying disease, tumor size, pathological type) and type of segmentectomy were comparable. There was significant difference in operative time[120(interquartile range, IQR 60-225)min vs. 155( IQR 75-330)min, P<0.001], blood loss[30( IQR 20-400) ml vs. 100( IQR 20-1 600) ml, P<0.001] between the robotic and VATS groups, respectively. But there was no significant difference in postoperative thoracic drainagevolume[4( IQR 1-15) days vs. 4( IQR 2-29) days, P=0.547], postoperative thoracic time[755( IQR 200-3 980)ml vs. 815( IQR 280-3 920)ml, P=0.902], pain score[2.33( IQR 0.88-4.75) points vs. 3.13( IQR 0.95-5.29)points, P=0.199], complications[7.4%(14/190) vs. 6.3%(12/190), P=0.303], postoperative hospital stay[7( IQR 3-19) days vs. 6( IQR 4-21) days, P=0.405] , number of lymph nodes[(4.83±3.18) vs.(6.15±4.1), P=0.255] between the robotic and VATS groups, respectively. The follow-up time was 6.5( IQR 1-26) months in the two groups, without recurrence, metastasis or death. Conclusion:Robotic lung segmentectomy is safe and feasible. This approach might lead to a better in operative time and blood loss. The short-term efficacy is similar with thoracoscopy, and the long-term efficacy needs further follow-up time.

ABSTRACT

Objective:To study the feasibility of establishing gastrointestinal anastomosis by magnetic compression technique in rabbits.Methods:Ten healthy New Zealand rabbits were selected as models for gastrointestinal anastomosis by magnetic compression technique. Daughter and parent magnets suitable for gastrointestinal anastomosis in rabbits were designed and manufactured. A daughter magnet was inserted into the stomach through the purse fistula in the lack of blood vessel area of gastric body, and was pushed into the duodenum along the intestinal tract. And then a parent magnet was inserted through the stomach fistula. The daughter and parent magnets were automatically attracted and pressed the gastric and intestinal walls after they were adjusted in the proper position. The stomach fistula was closed with purse string suture. After ischemia, necrosis, detachment of the tissues between magnets, gastrointestinal anastomosis was established, and the magnets and necrotic tissues were expelled together from the body through the digestive tract. Survival of experimental animals was observed. Anastomotic specimens were obtained one month after operation. The blasting pressure of anastomotic stoma was measured, and the healing of anastomotic stoma was observed with naked eyes.Results:According to the pre-designed operative route, 10 New Zealand rabbits all successfully completed the operation and survived one month after surgery. No complications occurred during perioperative period. The operation time was 35.80±4.71 min (range 28.00-43.00 min), and the magnet discharge time was 11.40±1.56 days (range 9.00-14.00 days). Anastomotic specimens were obtained one month after the operation. Gross observation showed that the anastomotic stoma of gastrointestinal bypass anastomosis healed well, and the surrounding tissues adhered slightly. The anastomotic bursting pressure was 103.00±7.95 mmHg (range 94.00-113.00 mmHg) (1 mmHg=0.133 kPa).Conclusion:The establishment of gastrointestinal anastomosis by magnetic compression technique in rabbits is simple and effective.

ABSTRACT

Objective:To design magnets to locate colorectal neoplasms based on magnetic tracer technology, and to test its feasibility and safety by animal experiments.Methods:The magnets used for endoscopic localization of colorectal tumors consist of a tracer magnet and a pursuit magnet, both of which are ring-shaped Nd-Fe-B magnets. Eight healthy Beagle dogs were used as animal models. Tumor locations were assumed in the different parts of the colon and rectum under colonoscopy. The tracer magnet was sent to the hypothetical tumors by endoscopic soft tissue clamp and fixed near the tumors. After 24 hours, laparoscopic surgery was performed under general anesthesia. The pursuit magnet was inserted near the resected colon or rectum through the main operating hole. The tracer magnet was absorbed to the pursuit magnet to identify the location of tumors.Results:The tracer magnet and pursuit magnet were successfully designed and processed. The suction force between the tracer magnet and the pursuit magnet at zero distance was 16 N. All the 8 Beagle dogs successfully received indwelling of magnets under colonoscopy, and no magnets fell off after 24 hours. After the placement of pursuit magnet under laparoscopy, the two magnets attracted each other rapidly and accurately, and successfully completed localization of tumor site without any damage during the operation.Conclusion:Colonoscopy combined with laparoscopy for colorectal neoplasms localization based on magnetic tracer technique is simple, accurate, safe and feasible.

ABSTRACT

@#Objective    To explore the clinical value of three-dimensional computed tomography bronchography and angiography (3D-CTBA) in robotic lung segmentectomy. Methods    A non-randomized control study was performed and continuously enrolled 122 patients who underwent robotic lung segmentectomy in our hospital from January 2019 to January 2020. 3D-CTBA was performed before operations in 53 patients [a 3D-CTBA group, including 18 males, 35 females, with a median age of 52 (26-69) years] and not performed in the other 69 patients [a traditional group, including 23 males, 46 females, with a median age of 48 (30-76) years]. The clinical data of the patients were compared between the two groups. Results    All the patients were successfully completed the surgery and recovered from hospital, with no perioperative death. The baseline characteristics of the patients were not significantly different between the two groups (P>0.05). No significant difference was found in the operative time [120 (70-185) min vs. 120 (45-225) min, P=0.801], blood loss [50 (20-300) mL vs. 30 (20-400) mL, P=0.778], complications rate (17.0% vs. 11.6%, P=0.162), postoperative hospital stay [7 (4-19) d vs. 7 (3-20) d, P=0.388] between the two groups. In the 3D-CTBA group, 5 (9.4%) patients did not find nodules after segmentectomy, and only 1 (1.9%) of them needed lobectomy, but in the traditional group, 8 (11.6%) patients did not find nodules and had to carry out lobectomy, the difference was statistically significant (P<0.05). The follow-up time was 10 (1-26) months, and during this period, there was no recurrence, metastasis or death in the two groups. Conclusion    3D-CTBA is helpful for accurate localization of nodules and reasonable surgical planning before operations, and reducing wrong resections in segmentectomy, without increasing the operation time, blood loss and complications. It is safe and effective in anatomical lung segmentectomy.
