@#Objective    To investigate the clinical efficacy of preoperative location of pulmonary nodules guided by electromagnetic navigation bronchoscopy (ENB). Methods    Patients who received preoperative ENB localization and then underwent surgery from March 2021 to November 2022 in the Department of Thoracic Surgery, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine were collected. The clinical efficacy and safety of ENB localization and the related factors that may affect the success of ENB localization were analyzed. Results    Initially 200 patients were included, among whom 17 undergoing preoperative localization and biopsy were excluded and a total of 183 patients and 230 nodules were finally included. There were 62 males and 121 females with a mean age of 49.16±12.50 years. The success rate of navigation was 88.7%, and the success rate of ENB localization was 67.4%. The rate of complications related to ENB localization were 2.7%, and the median localization time was 10 (7, 15) min. Multi-variable analysis showed that factors related to successful localization included distance from localization site (OR=0.27, 95%CI 0.13-0.59, P=0.001), staining material (OR=0.40, 95%CI 0.17-0.95, P=0.038), and staining dose (OR=60.39, 95%CI 2.31-1 578.47, P=0.014). Conclusion     ENB-guided preoperative localization of pulmonary nodules is safe and effective, and the incidence of complications is low, which can be used to effectively assist the diagnosis and treatment of early lung cancer.

An experimental study on the biological characteristics of SDF-1/CS/β-GP composite bio-membrane in vitro / 口腔医学

Objective@#To prepare a composite membrane by chitosan/β-sodium glycerophosphate(CS/β-GP) thermosensitive hydrogel combined with stromal cell derived factor-1(SDF-1) and observe its biological characteristics in vitro.@*Methods@#Different doses of SDF-1 were added into CS/β-GP solution and then the thermosensitive gel time was measured. The SDF-1/CS/β-GP solution was membrane paved and dried to prepare composite membranes. The morphological characteristics were observed by scanning electron microscope(SEM). Composite membranes were placed into cell culture medium, and the supernatant(n=3) was extracted after standing at 6, 12, 24, 36, 48, 60 h, respectively. The concentration of SDF-1 in the solution was measured. Bone mesenchymal stem cells(BMSCs) were cultured in the Transwell room, and the composite membranes containing different concentrations of SDF-1 were placed in the lower chamber. There were four groups(n=3): Group M0 used CS/β-GP membrane(control group), Group M1, M2, M3 used SDF-1/CS/β-GP membrane(SDF-1 was 100, 200, 400 ng/mL respectively). After culture for 6, 12 and 24 h, the cells under the membrane were preserved and Giemsa stained and counted. The absorbance(OD) value was measured by MTT method to calculate the cell proliferation rate. SPSS 19.0 was used for multi-factor analysis of variance.@*Results @#After adding a certain amount of SDF-1 into CS/β-GP solution, the gel time did not change significantly(P>0.05). The SDF-1/CS/β-GP membrane was translucent and porous at 37 ℃. In this experiment, the volumic mass of SDF-1 released by SDF-1/CS/β-GP composite membrane increased gradually with the experimental time(P<0.01). Transwell cell chemotaxis test showed that the number of BMSCs cells with directional migration increased with the prolongation of observation time(P<0.01) and the increase of SDF-1 volumic mass(P<0.01). In MTT test, the OD value of migration cell solution increased with the prolongation of time(P<0.01) and the increase of SDF-1 volumic mass(P<0.01). @*Conclusion@# The SDF-1/CS/β-GP composite membrane has a porous structure and biological activity of chemotactic BMSCs directional migration. It is a potential membrane for guided tissue regeneration.

Synergetic effect of temperature and PM2.5 on mortality of cardiovascular and cerebrovascular diseases / 上海预防医学

ObjectiveTo explore the synergetic effect of temperature and PM2.5 on cardiovascular and cerebrovascular diseases. MethodWe collected cardiovascular and cerebrovascular death cases，air pollution and meteorological data during the same period in Pudong New Area from 2013 to 2018.We used generalized additive models （GAMs） with poisson regression including non-stratification model， nonparametric bivariate response model and pollution-stratified parametric model， to assess the interaction between temperature and PM2.5 and on the number of cardiovascular cerebrovascular and cerebrovascular disease deaths. ResultsThe exposure-response relationship between temperature and the number of cardiovascular and cerebrovascular deaths exhibited "U" type and the most comfortable temperature was 18.9 ℃. When the concentrations of PM2.5 increased by 10 μg·m-3， the deaths of total， male， female， ≤75 years and >75 years increased， respectively， by 0.60%（95%CI： 0.30%‒0.91%）， 0.77%（95%CI：0.34%‒1.20%）， 0.46%（95%CI：0.05%‒0.86%）， 0.66%（95%CI：0.03%‒1.30%） and 0.59%（95%CI：0.26%‒0.92%）. With the increase of PM2.5 concentration level， the impact of temperature on cardiovascular and cerebrovascular diseases gradually increased， and the impact was the most significant when the concentration of PM2.5 was more than 150 µg·m-3. There were different sensitive people in different seasons. ConclusionPM2.5 concentration levels of mild pollution and above can exacerbate the negative effects of temperature on cardiovascular and cerebrovascular diseases.

Objective:To observe the effect of edaravone dexborneol on anxiety and depression after stroke in rats, and to explore its possible mechanism.Methods:Totally 120 healthy adult male SD rats were randomly divided into sham operation group (sham), ischemia-reperfusion group (MCAO), edaravone group (Eda) and edaravone dexborneol group (ED) with 30 in each group.The middle cerebral artery occlusion (MCAO) model was established by thread occlusion.Rats in ED group and Eda group were intraperitoneally injected with edaravone(8 mg·kg -1·d -1) and edaravone dexborneol(edaravone: 8 mg·kg -1·d -1, dexborneol: 2 mg·kg -1·d -1) respectively.And rats in the other two groups were intraperitoneally injected with the same volume of normal saline.Some rats were killed after continuous administration for 3 days to detect molecular indexes, and the remaining rats were tested for behavior after continuous administration for 14 days.The levels of neclear factor κB(NF-κB)、phosphorylated NF-κB(p-NF-κB)、tumor necrosis α(TNF-α)、interleukin 1β(IL-1β) were detected by Western blot.The mRNA levels of TNF-α, IL-1β, cluster of differentiation 86(CD86), cluster of differentiation 206(CD206), inducible nitric oxide synthase(iNOS) were detected by RT-qPCR.M1 type microglia labeled with CD68, microglia labeled with ionized calcium binding adaptor molecule 1(Iba1) and neurons labeled with microtubule-associated protein 2(MAP2) were detected by immunofluorescence staining.The cerebral infarction volume was measured by TTC staining.Depression and anxiety behavior after stroke in rats was observed by the open field test and elevated plus maze test.SPSS 17.0 software was used for statistical analysis of the data.One-way ANOVA was used for multiple group comparison, and LSD-t test was used for pairwise comparison. Results:(1) The behavioral results showed that 14 days after ischemia-reperfusion, the number of entering into the open arm, the time spent in the open arm, and the time spent in the central area of the open field in the MCAO group were lower than those in the sham group ( t=20.77, 6.02, 14.63, all P<0.05). The number of entering into the open arm, the time spent in the open arm, and the time spent in the central area of the field in the ED group ( (16.22±0.49) times, (69.11±17.08) s, (3.80±0.37) s) were higher than those in the MCAO group ( (8.14±0.60) times, (41.18±9.81) s, (0.33±0.39) s) ( t=4.69, 0.38, 2.27, all P<0.05) and Eda group ( (11.11±0.26) times, (45.26±17.16) s, (1.14±0.19) s) ( t=8.63, 2.50, 7.86, all P<0.05). (2) Western blot results showed that 3 days after ischemia-reperfusion, p-NF-κB/NF-κB, TNF-α, and IL-1β levels in the MCAO group were higher than those in the sham group ( t=15.35, 12.35, 7.23, all P<0.05). The levels of p-NF-κB/NF-κB (0.49±0.02), TNF-α (0.73±0.03), IL-1β (0.61±0.01) of ischemic penumbra cortex in ED group were significantly lower than those of the MCAO group ( (1.14±0.05), (1.13±0.07), (1.34±0.14)) ( t=14.58, 7.86, 5.65, all P<0.05) and Eda group ( (0.93±0.03), (0.89±0.02), (1.04±0.36) ) ( t=9.82, 3.07, 3.30, all P<0.05). (3) RT-qPCR results showed that the level of TNF-α mRNA (1.98±0.18), IL-1β mRNA (2.00±0.35), CD86 mRNA (1.56±0.20) and iNOS mRNA (2.01±0.12) in the peri-infarct cortex of ED group were lower than those in the MCAO group ( (5.12±0.24), ( 8.15±0.22), (6.03±0.13), (7.20±0.09) ) ( t=7.86, 16.88, 16.55, 37.25, all P<0.05) and Eda group ( (2.85±0.07), (5.43±0.26), (2.67±0.27), (3.58±0.11) ) ( t=3.71, 9.41, 4.13, 11.30, all P<0.05). The level of CD206 mRNA in the peri-infarct cortex of the ED group (3.98±0.25) was higher than that in the MCAO group (2.00±0.11) ( t=7.08, P<0.05) and Eda group (3.17±0.09) ( t=3.25, P<0.05). (4) The results of immunofluorescence staining showed that the ratio of polarized M1 microglia in the peri-infarct cortex and striatum in the ED group ((20.36±9.23)%, (18.26±5.98)%)were lower than those in the MCAO group ( (83.69±12.79)%, (61.25±33.26)%) ( t=5.23, 3.02, both P<0.05) and Eda group((42.16±13.13)%, (40.23±14.22)%)( t=3.12, 2.08, both P<0.05). In addition, the number of neurons marked with MAP2 of peri-infarct cortex in the MCAO group was lower than that in the sham group( t=8.02, P<0.05), and the number of neurons marded with MAP2 of peri-infarct cortex in the ED group ((53.07±17.90) /scope) was higher than that in the MCAO group ( (26.27±9.95) /scope) ( t=6.89, P<0.05) and Eda group ( (38.69±12.03)/scope) ( t=5.26, P<0.05). (5) The results of TTC staining showed that the cerebral infarction volume in ED group ( (10.31±1.03)%) was lower than that in the MCAO group ( (34.71±1.74)%) ( t=15.31, P<0.05) and Eda group ( (26.05±1.00)%) ( t=9.88, P<0.05). Conclusion:Edaravone dexborneol can alleviate anxiety and depression in rats with cerebral ischemia-reperfusion, which may be related to the inhibition of M1 microglial polarization, the down-regulation of NF-κB signaling pathway and the enhancement of neuronal structural stability.

Analysis of risk factors for complications after robot-assisted segmentectomy / 中国胸心血管外科临床杂志

@#Objective    To analyze the risk factors for complications after robotic segmentectomy. Methods    Clinical data of 207 patients undergoing robot-assisted anatomical segmentectomy in our hospital from June 2015 to July 2019 were retrospectively analyzed, including 69 males and 138 females with a median age of 54.0 years. The relationship between clinicopathological factors and prolonged air leakage, pleural effusion, and pulmonary infection after surgery was analyzed. Results    After robot-assisted segmentectomy, 20 (9.7%) patients developed prolonged air leakage (>5 d), 17 (8.2%) patients developed pleural effusion, and 4 (1.9%) patients developed pulmonary infection. Univariate logistic regression showed that body mass index (BMI, P=0.018), FEV1% (P=0.024), number of N1 lymph nodes resection (P=0.008) were related to prolonged air leakage after robot-assisted segmentectomy. Benign lesion was a risk factor for pleural effusion (P=0.013). The number of lymph node sampling stations was significantly related to the incidence of pulmonary infection (P=0.035). Multivariate logistic analysis showed that the BMI (OR=0.73, P=0.012) and N1 lymph node sampling (OR=1.38, P=0.001) had a negative and positive relationship with prolonged air leakage after robot-assisted segmentectomy, respectively. Conclusion    The incidence of pulmonary complications after robot-assisted segmentectomy is low. The lower BMI and more N1 lymph node sampling is, the greater probability of prolonged air leakage is. Benign lesions and more lymph node sampling stations are risk factors for pleural effusion and lung infection, respectively. Attention should be paid to the prevention and treatment of perioperative complications for patients with such risk factors.

Analysis of risk factors for lymph node metastasis in T2 stage non-small cell lung cancer / 中国胸心血管外科临床杂志

@#Objective    To explore the risk factors for lymph node metastasis in patients with T2 stage non-small cell lung cancer. Methods    The clinical data of 271 patients with non-small cell lung cancer who underwent surgical treatment in our hospital from 2014 to 2017 were collected, including 179 males and 92 females, with an average age of 62.73±0.58 years. The patients were divided into N0, N1, and N2 groups according to the lymph node metastasis status. The clinical data of the patients in different groups were compared. Results    The body mass index (BMI, P=0.043), preoperative lymph node enlargement (P<0.001), and tumor diameter (P<0.001) were significantly different among groups. The BMI (OR=1.131, 95%CI 1.001-1.277, P=0.048) and preoperative lymph node enlargement (OR=3.498, 95%CI 1.666-7.342, P=0.001) were independent risk factors for N2 lymph node metastasis, and tumor diameter was an independent risk factor for both N1 (OR=1.538, 95%CI 1.067-2.218, P=0.021) and N2 (OR=1.814, 95%CI 1.196-2.752, P=0.005) lymph node metastasis. Conclusion    Patients with high BMI or enlarged lymph nodes before surgery have a high risk for N2 lymph node metastasis, and those with large tumor diameter have a high risk for both N1 and N2 lymph node metastasis.

Segmentectomy of early stage lung cancer: From technology to clinical research / 中国胸心血管外科临床杂志

@#Segmentectomy is the removal of certain segments of the lung with lesions and retaining the normal lung tissue of the lobe. Lung segmentectomy is considered difficult due to the lack of clear anatomical boundaries between lung segments. Segmentectomy has a variety of indications, such as lung cancer, metastatic lung tumors, and many non-malignant diseases. In the treatment of early stage lung cancer, segmentectomy was initially considered only as a treatment option for patients not suitable for conventional lobectomy. As more evidence emerged, the indications for segmentectomy have continued to change over time, and segmentectomy has been widely performed in patients with early stage lung cancer. Theoretically, segmentectomy leads to better preservation of lung function than lobectomy, but the risk of incomplete tumor resection is higher, so the indication of segmentectomy has become a focus of debate. This article will introduce the surgical techniques of segmentectomy and summarize the published and unpublished clinical studies on segmentectomy for the treatment of early stage lung cancer.

Research progress of preoperative pulmonary rehabilitation for pulmonary malignant carcinoma / 中国胸心血管外科临床杂志

@#Surgery is an essential method of comprehensive treatment for lung cancer, but it also impairs patients’ cardiopulmonary function. A subset of patients who undergo surgery may suffer from postoperative complications, and even death. Preoperative pulmonary rehabilitation is a part of enhanced recovery after surgery, and can improve patients' cardiopulmonary function, reduce postoperative complication rate and shorten hospital stay. It has been already demonstrated a great value in lung cancer surgery. In this review, we summarized the three important components of preoperative pulmonary rehabilitation, including smoking cessation, chest physical therapy, and preoperative exercise training. Moreover, this review outlined the development of pulmonary rehabilitation for lung malignancies, aiming to promote its application and standardization.

Correlations among childhood trauma, autistic traits and dysexecutive functions in college students / 中国心理卫生杂志

Objective:To explore the relations among childhood trauma,autistic traits and dysexecutive functions in college students.Methods:Totally 2757 college students were assessed with the Childhood Trauma Questionnaire (CTQ).Sixty-three college students were randomly selected as the abused group according to the subscale cutoff point of CTQ Scale defined by Bernstein,and 93 students were randomly selected from students without history of childhood trauma as the control group.They were assessed with the Self-Rating Depression Scale (SDS),Autism Spectrum Quotient (AQ) and Dysexecutive Questionnaire (DEX) to measure depression,autistic traits and abnormality of executive functions,respectively.The individuals from the top and below 27％ of CTQ and AQ scores were defined as higher or lower-level different types of abused group and higher or lower-level autistic traits group,respectively.Results:The differences of DEX scores between higher or lower-level four types of CTQ (emotional abuse,physical abuse,sexual abuse,emotional neglect and physical neglect) and between higher or lower-level autistic traits group were significant (Ps ＜0.05).DEX scores in all higher-level groups were higher than all lower-level groups.Regression analysis showed that DEX score could be positively predicted by scores of emotional abuse,AQ and SDS (β =0.17-0.32,P ＜0.05).SDS score was a mediator between scores of emotional abuse and DEX,and between scores of autistic traits and DEX (95％ confidence interval were 0.05-0.32 and 0.07-0.55,respectively).Conclusion:Childhood trauma and autistic traits may positively predict dysexecutive function,and depression may play a mediating role between emotional abuse and dysexecutive function,and between autistic traits and dysexecutive function.

Application of different intrathoracic esophagogastric anastomosis in surgery for esophageal cancer / 中华胃肠外科杂志

Intrathoracic esophagogastric anastomosis is the mainstay of esophageal reconstruction after esophagectomy for the middle and lower esophageal cancer, which is the majority of esophageal cancer. In spite of the constant development of techniques and instruments for esophageal reconstruction, incidence of anastomotic complications stays high, including anastomotic leak and stricture. The current common esophagogastric anastomosis primarily consists of hand-sewn anastomosis and stapled anastomosis. This review presented different ways of intrathoracic esophagogastric anastomosis in reference to the literatures in China and abroad, and comparisons and analyses were made according to operative techniques, anastomotic complication rates, postoperative mortality rates, etc. The results demonstrated that various anastomotic methods had individual, advantages and disadvantages. Duration of stapled anastomosis is short, and linear-stapled anastomosis has a low incidence of anastomotic stricture. Traditional hand-sewn anastomosis, as a necessary skill for thoracic surgeons, shows great manipulative flexibility and reliability. Moreover, the advances in minimally invasive esophageal surgery, such as robot-assisted esophagectomy, increases the operability and efficiency of hand-sewn anastomosis with a promising perspective. In general, among diverse anastomotic methods, mortality does not differ, and the comparison of anastomotic leak rates requires further large clinical trials. Thoracic surgeons have to decide on the anastomotic method of every single case based on patient characteristics and technical proficiency, with the final aim of minimizing anastomotic complications and maximizing patient benefits.

Mechanism of neural plasticity of acupuncture on chronic migraine / 中国针灸

Chronic migraine is one of neurological disorders with high rate of disability, but sufficient attention has not been paid in this field. A large number of clinical studies have shown traditional Chinese acupuncture is a kind of effective treatment with less side effects. Through the analysis of literature regarding acupuncture and migraine published from 1981 to 2017 in CNKI and PubMed databases, the mechanism of neural plasticity of acupuncture on chronic migraine was explored. It was believed the progress of chronic migraine involved the changes of neural plasticity in neural structure and function, and the neural plasticity related with neural sensitization during the process of chronic migraine was discussed from three aspects of electrophysiology, molecular chemistry and radiography. Acupuncture could treat and prevent chronic migraine via the mechanism of neural plasticity, but there was no related literature, hindering the further spreading and development of acupuncture for chronic migraine.

Analysis of drug resistance and the correlation of drug resistance toP.areuginosa in our hospital from 2012 to 2016 / 中国生化药物杂志

Objective To understand the drug resistance and changes of Pseudomonas aeruginosa in Tianjin Medical University Eye Hospita and to explore the relationship between the drug resistance and the dosage of antimicrobial agents, so as to provide the basis for clinical rational drug use.MethodsUsage of antibiotics in our hospital during 2012 to 2016 were analyzed retrospectively, and the drug resistance of pseudomonas aeruginosa were calculated respectively.SPSS 22.0 software was used to analyze the drug resistance and the frequency of use of antimicrobial agents (DDDs).ResultsResistance rate of pseudomonas aeruginosa to aztreonam, ceftazidime and meropenem were decreased gradually.Resistance rate of pseudomonas aeruginosa to gentamicin increased gradually.The resistance of pseudomonas aeruginosa to piperacillin, imipenem, cefepime, evil ciprofloxacin, piperacillin/tazobactam tazobactam and cefempidone/sulbactam is in a state of fluctuation.Piperacillin DDDs were significantly negatively correlated with gentamicin resistance.There was a significant positive correlation between imipenem DDDs and gentamicin resistance and there was a significant negative correlation between imipenem DDDs and drug resistance rates of piperacillin, imipenem, ceftazidime, meropenem, levofloxacin and cefoperazone/sulbactam.There was a significant positive correlation between aztreonam DDDs and ceftazidime, meropenem, ciprofloxacin and cefoperazone/sulbactam, There was a significant negative correlation between cephalosporin DDDs and gentamicin resistance rates.There was a significant positive correlation between the DDDs of piperacillin/tazobactam and the resistance rate of piperacillin/tazobactam;the resistance rates of cefoperazone/sulbactam DDDs to aztreonam and meropenem were Significant negative correlation.ConclusionDrug resistance of pseudomonas aeruginosa and the dosage of clinical antibacterial drug is closely related, suggesting that clinicians should use antibiotics for clinical rationally, in order to reduce the number of drug resistance of pseudomonas aeruginosa.
