  • Effect of sarcopenia on the prognosis of patients with early non-small cell lung cancer after surgery and postoperative chemotherapy

    Objective To investigate the prognostic value of sarcopenia in patients with early non-small cell lung cancer (NSCLC) after surgery and chemotherapy. Methods This study included 592 patients with early non-small cell lung cancer who received lung cancer resection from January 2014 to December 2015, and they were divided into two groups: 473 patients received surgery alone (the surgery group), 119 patients received chemotherapy after surgery (the postoperative chemotherapy group), and the two groups were divided into sarcopenia group and non-sarcopenia group. General clinical data, laboratory data, and imaging data of these patients were compared. Results The median follow-up time of 592 patients was 69.1 months [95% confidential interval (CI) 64.9 - 78.2], and 110 patients were with sarcopenia (18.6%). Multivariate analysis showed that sarcopenia was an independent adverse prognostic factor in the surgery group [hazard ratio (HR) 6.56; 95%CI 1.86 to 14.78; P=0.01]. For patients undergoing postoperative chemotherapy, skeletal muscle mass index was reduced after chemotherapy, and sarcopenia was an independent predictor of poor prognosis (HR 5.77; 95%CI 0.96 to 20.60; P<0.05). Conclusions Sarcopenia is an independent poor prognostic factor for patients with early NSCLC undergoing surgery and postoperative chemotherapy. Assessment of sarcopenia before surgery and postoperative chemotherapy is helpful to improve the prognosis of patients with early NSCLC.

  • Electromagnetic navigational bronchoscopy compared with transthoracic needle biopsy for diagnostic yield and safety in peripheral pulmonary lesions

    Objective To evaluate the diagnostic yield and safety of two biopsy methods, electromagnetic navigational bronchoscopy (ENB) and transthoracic needle biopsy (TTNB), in peripheral pulmonary lesions. To select a low-risk and high-benefit biopsy method based on the clinical characteristics of the lesions and patients. Methods A retrospective analysis was conducted on inpatients who underwent ENB and/or TTNB for peripheral pulmonary lesions in Huadong Hospital Affiliated to Fudan University. Propensity score matching was used to compare the diagnostic yield and safety of the two biopsy methods. Results A total of 126 patients were included in the ENB group, and 104 patients in the TTNB group. After propensity score matching, 83 matched pairs were obtained. The TTNB group exhibited a significantly higher diagnostic yield compared with the ENB group (90.4% vs. 48.2%, P<0.001), but it was also associated with a higher incidence of pneumothorax (1.2% vs. 21.7%, P<0.001). In the ENB group, the diagnostic efficacy was correlated with lesion diameter (P<0.001, OR=0.183, 95%CI 0.071 - 0.470), but there was no statistically significant difference in the diagnostic yield among different lung segments (P>0.05). In the TTNB group, lesion characteristics did not significantly affect the diagnostic yield, but a lesion diameter ≤30 mm (P=0.019, OR=5.359, 95%CI 1.320 - 21.753) and a distance from the pleura ≥20mm (P=0.030, OR=6.399, 95%CI 1.192 - 34.360) increased the risk of pneumothorax. When stratified based on lesion and patient blood characteristics, no significant difference was found in the diagnostic yield between the two groups for characteristics such as left upper lobe (P=0.195), right middle lobe (P=0.333), solid with cavity (P=0.567), or abnormal serum white blood cell count (P=0.077). However, the incidence of pneumothorax in the TTNB group was higher than that in the ENB group. Conclusions The diagnostic yield of ENB is affected by the size of the lesion, while the incidence of pneumothorax in TTNB is influenced by both lesion size and distance from the pleura. In cases with lesions located in the left upper lobe, right middle lobe, solid with cavity, or with abnormal serum white blood cell count, selecting ENB for biopsy is considered preferable to TTNB.

  • Construction and evaluation of nomogram prognostic model based on preoperative systemic immune-inflammation index and controlling nutritional status score after radical resection of pancreatic ductal adenocarcinoma

    ObjectiveTo explore the factors of affecting the prognosis of pancreatic ductal adenocarcinoma (PDAC) after radical resection based on the preoperative systemic immune-inflammation index (SII) and the controlling nutritional status (CONUT) score and to establish a prognostic prediction model.MethodsThe clinicopathologic data of patients diagnosed with PDAC from January 2014 to December 2019 in the Second Hospital of Lanzhou University were retrospectively analyzed. The X-tile software was used to determine the optimal cut-off value of SII. The Kaplan-Meier method was used to analyze survival. The Cox proportional hazards regression model was used to conduct multivariate analysis of prognostic factors of PDAC after radical surgery. R4.0.5 software was used to draw a nomogram prediction model of 1-, 2-, and 3-year survival rates, then evaluate the effectiveness of the prediction model and establish a web page calculator.ResultsA total of 131 patients were included in the study. The median survival time was 18.6 months, and the cumulative survival rates at 1-, 2-, and 3-year were 73.86%, 36.44%, and 11.95%, respectively. The optimal cut-off value of preoperative SII was 313.1, and the prognosis of patients with SII>313.1 was worse than SII≤313.1 (χ2=8.917, P=0.003). The results of multivariate analysis suggested that the age>65 years old, clinical stage Ⅲ and Ⅳ, preoperative SII>313.1, and CONUT score >4 were the independent factors influencing the prognosis (overall survival) for PDAC after radical resection (P<0.05). The internal verification consistency index (C-index) of the nomogram prediction model including age, clinical stage, preoperative SII, CONUT score and postoperative chemotherapy was 0.669. The survival predicted by the nomogram correction curve fitted well with the observed survival. The decision curve analysis showed that the nomogram prediction model had a wider clinical net benefit (Threshold probability was 0.05–0.95), and the web calculator worked well.ConclusionsAge, clinical stage, preoperative SII, CONUT score are independent influencing factors for prognosis after radical PDAC surgery. Nomogram prediction model included these independent influencing factors is more accurate and web calculator will be more convenient for doctors and patients.

  • The effect of continuous renal replacement therapy to treat sepsis associated acute kidney injury in very elderly patients

    ObjectiveTo explore the effect of continuous renal replacement therapy (CRRT) to treat sepsis associated acute kidney injury (AKI) in patients aged over 80.MethodsForty-one patients diagnosed with sepsis and AKI were enrolled in geriatric RICU department of Huadong Hospital from January 2013 to July 2018, 38 patients were male and 3 were female. All patients were treated with anti-infection and fluid resuscitation therapy. After comprehensive judgment of the indication of renal replacement, they were divided into two groups by the choices of using CRRT. There were 20 patients in CRRT group and 21 in control group. Clinical data such as age, body mass index, previous diseases, 28-day mortality rate, blood cells, APACHEⅡ as well as SOFA scores were compared between two groups. Blood renal function and inflammatory markers at the first day were also compared to those after 3-day treatment of initial time.ResultsNo statistical difference was observed in sex ratio, age, body mass index and previous diseases between two groups (all P>0.05). There was also no difference in APACHEⅡ score, SOFA score, blood cells, hemoglobin and survival time. The 28-day mortality rate in CRRT group was lower than that in control group (P<0.05). The levels of serum UA and C reactive protein (CRP) in CRRT group decreased after 3-day treatment compared with those at the onset, and the differences were statistically significant (all P<0.05). The level of serum blood urea nitrogen (BUN), creatinine (Cr), uric acid (UA) and cystain C in control group increased after 3 days compared with those at the onset, and the difference were statistically significant (all P<0.05). There was no significant difference in serum BUN, Cr, UA, cystain C, CRP and procalcitonin (PCT) between two groups at the onset (all P>0.05). After 3 days of CRRT, the levels of serum PCT, BUN, Cr and UA in CRRT group were lower than those in the control group (all P<0.05).ConclusionCRRT can improve hyperuricemia, control deterioration of renal function, reduce early systemic inflammatory response and 28-day mortality rate in aged patients with sepsis and AKI.

  • Chlorhexidine-grafted phenolamine coating to improve antibacterial property of the titanium surface

    Objective To investigate the physicochemical properties of pure titanium surface grafted with chlorhexidine (CHX) by phenolamine coating, and to evaluate its antibacterial activity and osteoblast-compatibility in vitro. MethodsControl group was obtained by alkali and thermal treatment, and then immersed in the mixture of epigallocatechin-3-gallate/hexamethylene diamine (coating group). Phenolamine coating was deposited on the surface, and then it was immersed in CHX solution to obtain the grafted surface of CHX (grafting group). The surface morphology was observed by scanning electron microscope, the surface element composition was analyzed by X-ray photoelectron spectroscopy, and the surface hydrophilicity was measured by water contact angle test. Live/dead bacterial staining, nephelometery, and inhibition zone method were executed to evaluate the antibacterial property. Cytotoxicity was evaluated by MTT assay and cell fluorescence staining. Bacteria-MC3T3-E1 cells co‐culture was conducted to evaluate the cell viability on the samples under the circumstance with bacteria. Results Scanning electron microscope observation results showed that deposits of coating group and grafting group increased successively and gradually covered the porous structure. X-ray photoelectron spectroscopy results showed the peak of N1s enhanced and the peak of Cl2p appeared in grafting group. Water contact angle test results showed that the hydrophilic angle of three groups increased in turn, and there was significant difference between groups (P<0.05). Live/dead bacteria staining results showed that the grafting group had the least amount of bacteria adhered to the surface and the proportion of dead bacteria was high. The grafting group had a transparent inhibition zone around it and the absorbance (A) value did not increase, showing significant difference when compared with control group and coating group (P<0.05). MTT assay and cell fluorescence staining results showed that the number of adherent cells on the surface of the grafting group was the least, but the adherent cells had good proliferation activity. Bacteria-cell co-culture results showed that there was no bacteria on the surface of grafting group but live cells adhered well. ConclusionCHX-grafted phenolamine coating has the ability to inhibit bacterial adhesion and proliferation, and effectively protect cell adhesion and proliferation in a bacterial environment.
