ABSTRACT
Objective:To explore the practical value of general anesthesia with non-intubated spontaneous breathing in uniportal thoracoscopic surgery in elderly patients.Methods:Clinical data of 86 elderly patients undergone uniportal thoracoscopy surgery during hospitalization at our hospital between March 2020 and December 2021 were retrospectively reviewed and analyzed.Based on the anesthesia intubation method, they were divided into a non-intubated spontaneous breathing video-assisted thoracic surgery group(NI-VATS group)and a one-lung ventilation video-assisted thoracic surgery group(OLV-VATS group), with 43 cases in each group.Data were compared on the inflammatory indexes, preparation time for anesthesia, time to awakening after anesthesia, intraoperative lung collapse score, mediastinal flutter score, time to postoperative feeding, digestive tract complications, sore throat, postoperative pulmonary atelectasis, and hospitalization time.Results:Compared with the OLV-VATS group, the NI-VATS group had a shorter anesthesia preparation time [(19.8±2.6)min vs.(32.3±4.5)min, t=-15.77, P<0.001]and a shorter time to awakening [(6.8±2.1)min vs.(11.9±2.9)min, t=-9.485, P<0.001], slightly poorer operating field during surgery, an unfavorable lung collapse score [(2.5±0.7) vs.(1.8±0.7) t=4.704, P<0.001], worse mediastinal flutter [(2.1±0.6) vs.(1.3±0.5), t=6.514, P<0.001]. Lower procalcitonin(PCT)[(0.189±0.130)μg/L vs.(0.264±0.123)μg/L, t=-2.744, P=0.007), a shorter time to postoperative feeding [(3.4±1.0)h vs.(5.5±1.0)h, t=-9.55, P<0.001], and lower rates of digestive tract reactions(4.7% vs.20.9%, χ2=5.108, P=0.024)and throat pain(4.7% vs.23.3%, χ2=6.198, P=0.013), and a shorter length of hospital stay [(3.8±0.3)d vs.(4.9±0.8)d, t=-7.266, P<0.001]. Conclusions:For the elderly patients undergoing uniportal thoracoscopic surgery, non-intubated spontaneous breathing may somewhat obstruct the operating field, but it can shorten the time of anesthesia and the time to awakening, does not increase complications from anesthesia and surgery, favors rapid postoperative recovery for patients and therefore should be promoted.
ABSTRACT
Objective To investigate the effect of docosahexaenoic acid (DHA) on the sensitivity of esophageal carcinoma cell line EC9706 to cisplatin and the mechanism behind this effect.Methods EC9706 cells were randomly divided into 5 groups:control group,DHA group,cisplatin (DDP) group,DHA+DDP group and endoplasmic reticulum stress (ERS) activation tunicamycin (TM) group (DHA+DDP+TM group).MTT method was used to evaluate inhibition ratio of cell proliferation.The apoptotic ratio was examined by flow eytometry.Western blot was used to detect the protein expressions of apoptosis cytokines (caspase-3 and Bcl-2) and ERS cytokines [glucose-regulated protein 78 (GRP78) and inositol-requiring enzyme 1 (IRE-1)].Results DHA causes concentration-dependent and time-dependent inhibition of the proliferation of EC9706 cells (P=0.00).DHA significantly enhanced the sensitivity of esophageal carcinoma cell line EC9706 to cisplatin.Compared to DDP treatment alone,the inhibition ratio [(60.19±5.05)％ vs.(36.72±3.52)％,P=0.02] and apoptotic ratio [(54.88±4.94)％ vs.(39.74±4.64)％,P=0.03] of EC9706 cells were enhanced by DHA+DDP treatment.Western blot showed that the expression of apoptotic factor caspase-3 protein was increased by DHA+DDP treatment.Meanwhile,the protein expressions of anti-apoptotic factor (Bcl-2) and ERS-related factors (GRP78 and IRE-1) were significantly inhibited by DHA+DDP treatment (P=0.01).However,the salutary effects of DHA were reversed by ERS activation tunicamycin.Conclusion DHA enhances the sensitivity of esophageal carcinoma cell line EC9706 to cisplatin,the mechanism of which may be the suppression of ERS response.
ABSTRACT
Objective The goal of the study was to assess the lethal effect of cytotoxic lymphocyte against A549 cells induced by dendritic cells (DC) pulsed with A549 lysate and transfected with GM-CSF recombinant adenovirus. Methods The cytotoxic lymphocyte against A549 cells were induced by culturing with DCs, which pulsed with A549 antigens and transfected with GM-CSF recombinant adenovirus. The of effector/target ratio, the killing rates of N-DC group, A-DC group and G-A-DC group were (1.9±0.7) %,effector/target ratio, the killing rates of N-DC group, A-DC group and G-A-DC group were (5.3±0.2) %, (40.5±7.7) % and (72.5±4.7) %, respectively. We found that the killing rate of G-A-DC group was the highest by statistics. Conclusion The cytotoxic lymphocyte against A549 cells can be induced by DCs pulsed with A549 lysate ,and the lethal effect of CTLs can be enhanced when DCs were infected with GM-CSF recombinant adenovirus.
ABSTRACT
Objective To investigate the expression of CD24 and FAK in the invasive breast ductal carcinoma tissues and their clin-ical significance. Methods Tissues were obtained from 86 patients with breast carcinoma and 30 non-cancer specimens. The expression of CD24 and FAK was detected by immunohistochemical technique (ElivisionTMPlus) and their correlation with tumor clinicopathological char-acters was analyzed. Results The positive rate of CD24 and FAK expression in 86 cases of breast carcinoma was 87.2% (75/86) and 72.1% (62/86) respectively, which was significantly different from that in control group(P<0.01). Expression of CD24 was significantly correlated with axillary lymph node metastasis(P<0.01). Expression of FAK was correlated with histopathologic grade, axillary lymph node metastasis and clinical stage (P<0.05). There was a positive correlation between the expressions of CD24 and FAK in breast carci-noma tissues (rs = 0.222, P < 0.05). Conclusion Expression of CD24 and FAK are closely correlated with the development of breast carcinoma and there is a markedly positive correlation between CD24 and FAK expression. These indexes can be helpful in understanding the biological behaviors and predicting the prognosis of breast carcinoma.
ABSTRACT
Objective To investigate the expression of CD24 and Ki67 in the invasive breast ductal car-cinoma tissues, so as to assess the role of CD24 protein in the carcinogenesis and progression of breast canc-er. Methods The expression of CD24 and Ki67, Bcl-2 was examined by immunohistochemically in 86 breast cancer specimens and 30 non-cancer specimens ( ElivisionTM Plus). The relationship between CD24 expression and Ki67, Bcl-2, patient age, tumor size, histopathologic grade, axillary lymphnode metastasis, and clinical stage of breast cancer was analyzed. Results In 86 eases of invasive breast ductal carcinoma, the positive incidences of CD24 was 87.2% (75/86), which distinguished apparently from those of the con-trol group( P <0.01 ). In breast carcinoma tissues, the expression of CD24 was positively related to axillary lymphnode metastasis(P <0.01 ), but was not related to patients age,tumor size, histopathologic grade and clinical stage(P>0.05). CD24 expression was positively related to Ki67 (P<0.01 ) and negatively relat-ed to Bcl-2(P>0.05). Conclusion CD24 expression was related to the proliferation, invasion and me-tastasis of breast cancer cells and it can serve as an important marker for predicting biological behavior and prognosis of tumors.
ABSTRACT
Objective: To study the probiotic properties of 12 selected strains of lactobacilli.Methods: The probiotic properties of 12 selected strains of lactobacilli were investigated for their resistance to pH 2.5 and 0.3% oxgall,their adhesion to Caco-2 cells and antimicrobial activity against enteric pathogenic bacteria.Results: The 12 strains all showed relatively high resistance to acid and bile salt and varied antimicrobial activities against pathogenic bacteria of intestinal infection.Lactobacillus johnsonii JCM1022 exhibited a broad inhibitory effect on enteric pathogenic bacteria,especially on enteropathgenic E.coli and Salmonella enteritidis,while Lactobacillus reuteri JCM1081 possessed a high activity of adhesion to Caco-2 cells(495.07?80.03).Conclusion: Among the 12 strains,Lactobacillus johnsonii JCM1022 and reuteri JCM1081 are qualified candidates for clinical application.
ABSTRACT
To determine the effect of pre-operative chemotherapy on apoptosis in breast cancer and to evaluate its signif icance as a prcgnostic marker. MethodsPatients with breast cancer were divided into preoperative chemotherapy group (40 cases)and control group (42 cases). Two groups were analyzed for the appearance of apoptosis by using TUNEL method and electron mi croscope in tissue sections. ResultsApoptosis occurred in 92.5 % of preoperative chemotherapy group and in 78.5 % of control group. The apoptotic indexes were 19.37 + 6.49 and 9.26 + 5.04 ( P ＜ 0.01 ) respectively. Low apoptotic index was related to disease-free survival of patients with breast cancer (P ＜ 0.01 ). ConclusionThe preoperative chemotherapy can induce apoptcsis of breast cancer and improve disease-free survival.
