BACKGROUND:Nickel-titanium memory-shape compression anastomosis clip (Ni-Ti CAC) has been used in gastrointestinal anastomosis, but its efficacy and safety still remain controversial.OBJECTIVE:To evaluate the efficacy and safety of Ni-Ti CAC in gastrointestinal anastomosis.METHODS:A computer-based online research of PubMed, EMbase, Cochrane Library, CBM, CNKI, and VIP databases was performed for articles published before January 15th, 2017 using the keywords of nickel-titanium, compression anastomosis clip, anastomosis, gastric, jejunum, ileum, small intestine, colon, rectum, and large intestine in English and Chinese, respectively. The randomized controled trials about Ni-Ti CACversus conventional methods for gastrointestinal anastomosis were included. Meta-analysis of the anastomosis time, time of exsufflation, and hospitalization time was performed, and sequential analysis was conducted on TSA v0.9 software.RESULTS AND CONCLUSION:A total of 18 eligible randomized controlled trials were enroled, involving 1860 patients. Ni-Ti CAC could reduce the anastomosis time [MD=-3.83, 95%CI(-6.48,-1.19),P=0.004] and time of exsufflation [MD=-0.14, 95%CI(-0.22,-0.05),P=0.002], but there was no significant difference in the hospitalization time [MD=-0.83, 95%CI(-1.82, 0.16), P=0.10]. The quality was ranked as low level based on GRADE system. The time of exsufflation of Ni-Ti CAC was superior to that of conventional method, which was confirmed by sequential analysis. One case of death was reported and incision infection was the most common adverse effects; additionaly, pulmonary embolism and abdominal pain occurred. To conclude, Ni-Ti CAC can facilitate gastrointestinal anastomosis, accelerate the time of exsufflation, and holds a good safety. However, more multicenter and high-quality randomized controlled trials are needed.

Objective:To analyze the law of distant metastasis in patients with small lung adenocarcinoma with different CT findings, and to explore the feasibility of different preoperative examination methods for small lung adenocarcinoma with different imaging characteristics.Methods:Clinicopathological data of cT1a-cN0 lung adenocarcinoma patients admitted to the respiratory center of China-Japan Hospital from January 2017 to December 2018 were retrospectively collected. A total number of 785 patients were included, including 289 males and 496 females. SPSS 22.0 was used for statistical analysis.Results:A total number of 785 patients were included in this study, including 287 pure ground-glass nodule (GGN) patients, 111 GGN predominant patients, 221 solid predominant patients and 166 solid nodule patients. Among the included patients, 8 had distant metastasis, including 6 with bone metastasis, 1 with brain metastasis and 1 with brain and adrenal metastasis. No distant metastasis was observed in the patients with pure GGN and GGN predominant nodule, while 1 solid predominant patients had distant metastasis, and 7 patients with solid nodules had distant metastasis. The probability of distant metastasis was 0.5% for the solid predominant patients and 4.2% for the solid nodule patients. Univariate analysis results showed that CEA level ( P=0.030), the largest diameter of the lung window tumor ( P=0.003), the largest diameter of the solid component of the lung window tumor ( P<0.001), the largest area of the lung window tumor ( P=0.002), mediastinal window tumor maximum area ( P<0.001), CTR ( P<0.001), TDR ( P<0.001), and pleural indentation sign ( P=0.037) were risk factors for distant metastases. Multivariate analysis showed that CEA ( OR=1.019, 95% CI: 1.002-1.037, P=0.028) and TDR ( OR=0.000, 95% CI: 0.000-0.310, P=0.001) were independent risk factors of distant metastasis. Conclusion:For patients with pure GGN and GGN predominant nodule, preoperative examination could not be required, but for pure solid nodules, it is necessary to perform relevant preoperative examination including skull MRI before surgery to exclude distant metastasis.

Objective:To analyze the clinical characteristics of patients with Vibrio vulnificus infection, share diagnosis and treatment experience, and establish a rapid diagnosis procedure for this disease. Methods:This study was a retrospective case series study. From January 2009 to November 2022, 11 patients with Vibrio vulnificus infection who met the inclusion criteria were admitted to the Department of Burns and Wound Repair of Guangdong Provincial People's Hospital Affiliated to Southern Medical University. The gender, age, time of onset of illness, time of admission, time of diagnosis, route of infection, underlying diseases, affected limbs, clinical manifestations and signs on admission, white blood cell count, hemoglobin, platelet count, C-reactive protein (CRP), alanine transaminase (ALT), aspartate transaminase (AST), creatinine, procalcitonin, albumin, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and blood sodium levels on admission, culture results and metagenomic next-generation sequencing (mNGS) results of pathogenic bacteria and the Vibrio vulnificus drug susceptibility test results during hospitalization, treatment methods, length of hospital stay, and outcomes of all patients were recorded. Comparative analysis was conducted on the admission time and diagnosis time of patients with and without a history of exposure to seawater/marine products, as well as the fatality ratio and amputation of limbs/digits ratio of patients with and without early adequate antibiotic treatment. For the survived patients with hand involvement, the hand function was assessed using Brunnstrom staging at the last follow-up. Based on patients' clinical characteristics and treatment conditions, a rapid diagnosis procedure for Vibrio vulnificus infection was established. Results:There were 7 males and 4 females among the patients, aged (56±17) years. Most of the patients developed symptoms in summer and autumn. The admission time was 3.00 (1.00, 4.00) d after the onset of illness, and the diagnosis time was 4.00 (2.00, 8.00) d after the onset of illness. There were 7 and 4 patients with and without a history of contact with seawater/marine products, respectively, and the admission time of these two types of patients was similar ( P>0.05). The diagnosis time of patients with a history of contact with seawater/marine products was 2.00 (2.00, 5.00) d after the onset of illness, which was significantly shorter than 9.00 (4.25, 13.00) d after the onset of illness for patients without a history of contact with seawater/marine products ( Z=-2.01, P<0.05). Totally 10 patients had underlying diseases. The affected limbs were right-hand in 8 cases, left-hand in 1 case, and lower limb in 2 cases. On admission, a total of 9 patients had fever; 11 patients had pain at the infected site, and redness and swelling of the affected limb, and 9 patients each had ecchymosis/necrosis and blisters/blood blisters; 6 patients suffered from shock, and 2 patients developed multiple organ dysfunction syndrome. On admission, there were 8 patients with abnormal white blood cell count, hemoglobin, and albumin levels, 10 patients with abnormal CRP, procalcitonin, and NT-proBNP levels, 5 patients with abnormal creatinine and blood sodium levels, and fewer patients with abnormal platelet count, ALT, and AST levels. During hospitalization, 4 of the 11 wound tissue/exudation samples had positive pathogenic bacterial culture results, and the result reporting time was 5.00 (5.00, 5.00) d; 4 of the 9 blood specimens had positive pathogenic bacterial culture results, and the result reporting time was 3.50 (1.25, 5.00) d; the mNGS results of 7 wound tissue/exudation or blood samples were all positive, and the result reporting time was 1.00 (1.00, 2.00) d. The three strains of Vibrio vulnificus detected were sensitive to 10 commonly used clinical antibiotics, including ciprofloxacin, levofloxacin, and amikacin, etc. A total of 10 patients received surgical treatment, 4 of whom had amputation of limbs/digits; all patients received anti-infection treatment. The length of hospital stay of 11 patients was (26±11) d, of whom 9 patients were cured and 2 patients died. Compared with that of the 6 patients who did not receive early adequate antibiotic treatment, the 5 patients who received early adequate antibiotic treatment had no significant changes in the fatality ratio or amputation of limbs/digits ratio ( P>0.05). In 3 months to 2 years after surgery, the hand function of 8 patients was assessed, with results showing 4 cases of disabled hands, 2 cases of incompletely disabled hands, and 2 cases of recovered hands. When a patient had clinical symptoms of limb redness and swelling and a history of contact with seawater/marine products or a pre-examination triage RiCH score of Vibrio vulnificus sepsis ≥1, the etiological testing should be initiated immediately to quickly diagnose Vibrio vulnificus infection. Conclusions:Vibrio vulnificus infection occurs most frequently in summer and autumn, with clinical manifestations and laboratory test results showing obvious infection characteristics, and may be accompanied by damage to multiple organ functions. Both the fatality and disability ratios are high and have a great impact on the function of the affected limbs. Early diagnosis is difficult and treatment is easily delayed, but mNGS could facilitate rapid detection. For patients with red and swollen limbs accompanied by a history of contact with seawater/marine products or with a pre-examination triage RiCH score of Vibrio vulnificus sepsis ≥1, the etiological testing should be initiated immediately to quickly diagnose Vibrio vulnificus infection.

Objective:To evaluate the effect of interstitial lung disease(ILD) on postoperative morbidity and mortality in pulmonary resection for lung cancer patients.Methods:We retrospectively analyzed 971 patients undergoing pulmonary operation from January 2010 to January 2018 in our hospital. Clinical data including age, sex, history of chronic obstructive pulmonary disease(COPD), smoking history, smoking index, American Society of Anesthesiologists(ASA) classification, forced expiratory volume in 1 s(FEV1) % predict, surgical procedure, video assisted thoracoscopic surgery(VATS) or not, intraoperative blood transfusion, anesthesia time, operation time/one-lung ventilation time, blood loss, histology, postoperative morbidity, 60-days mortality, onset of acute exacerbation of interstitial lung disease(AE-ILD), drainage, extubation time, and postoperative stay were collected and analyzed.Results:There were 80(8.2%) and 891(91.8%) patients in ILD and non-ILD group, respectively. AE-ILD occurred in 5 patients, with a 60-day mortality of 80%. A multivariate regression analysis identified that the sex( P=0.023), ILD( P=0.001), COPD( P=0.027) were independent risk factors for postoperative morbidity. ILD( P=0.023) and postoperative morbidity( P=0.001) were independent risk factors for 60-day mortality in multivariate analysis. Conclusion:Patients with ILD had a higher incidence of postoperative morbidity and 60-day mortality. Based on the obvious postoperative morbidity and mortality, special attention and management should be taken in ILD patients.

BACKGROUND:
Cisplatin acquired resistance is a vital problem in the chemotherapy of non-small cell lung cancer, which needs to be further addressed. In recent years, obtaining drug resistant cells from cell cultivation and serving for metabolomics research to find differential metabolites and get potential biomarkers, is a good reference for clinical research and cancer treatment. This study aimed to obtain metabolite information related to cisplatin resistance through metabolomics analysis.
METHODS:
Metabolites were extracted from A549 cells and cisplatin resistant A549/DDP cells, and ultraperformance liquid chromatography coupled with time of flight mass spectrometry was used to perform metabolomic analysis of endogenous molecules of the two cells and obtain metabolic differences.
RESULTS:
Through data analysis, 40 metabolites were identified as differential metabolites, mainly involving phospholipids, fatty acids, amino acids and metabolites related to energy metabolism.
CONCLUSIONS
The drug resistance of A549/DDP cells may be caused by the changes of cell membrane structure and related metabolic pathways.
