        • Alteration of Fas/FasL mRNA Expression in Hepato carcinoma and Its Significance

          【Abstract】ObjectiveTo measure the expressions of Fas/FasL mRNA in normal liver, adjacent non-cancerous liver parenchyma and hepatocarcinoma, and to explore the relationship between the expressions of Fas/FasL mRNA in those tissues and the hepatocellular carcinogenesis. MethodsSemi-quantity reverse transcript-ploymerase chain reaction(QRTPCR) were performed to measure the relative quantity of the Fas and FasL mRNA expressions in normal liver (n=25), adjacent noncancerous liver parenchyma(n=40) and hepatocarcinoma(n=40). ResultsThe relative quantity of Fas and FasL mRNA expressed in normal liver, adjacent non-cancerous liver parenchyma and hepatocarcinoma were 0.792±0.039 vs 0.245±0.043,0.857±0.031 vs 0.429±0.035 and 0.473±0.047 vs 0.185±0.041, respectively. The relative quantity of Fas mRNA expression in hepatocarcinoma was lower than that of normal liver tissue and adjacent non-cancerous liver parenchyrna (P<0.05). The relative quantity of FasL mRNA expression in hepatocarcinoma was also lower than that of normal liver tissue (P<0.05) and adjacent non-cancerous liver parenchyma (P<0.01), but its expression in adjacent non-cancerous liver parenchyma was higher than that of normal liver tissue (P<0.05).ConclusionHepatorcarcinoma may escape the immune surveillance of the host, not only by means of reducing Fas expression, but also through adjacent non-cancerous liver parenchyma’s increasing expression of FasL to induce apoptosis of contact lymphocyte which highly expresses Fas.

        • Expressions of Osteopontin and Related Factors in Breast Cancer Tissues and Its Clinical Significance

          Objective To detect the expressions of osteopontin (OPN), breast tumor kinase (Brk), and vascular endothelial growth factor (VEGF) in the breast cancer tissue, the adjacent (2cm) normal breast tissue, and the distal(>5cm) normal breast tissue, and analyze their clinical significances. Method The immunohistochemical method was used to detect the expressions of OPN, Brk, and VEGF in the breast cancer tissue, the adjacent (2cm) normal breast tissue, and the distal (>5cm) normal breast tissue from 40 cases of breast cancer. Results ① The expressions of OPN,Brk, and VEGF in the breast cancer tissue were significantly higher than those of the adjacent (2cm) normal breast tissue and the distal (>5cm) normal breast tissue (P<0.01), the expression of Brk in the adjacent (2cm) normal breast tissue was significantly higher than that of the distal (>5 cm) normal breast tissue (P<0.05). ② In the breast cancer tissue, the OPN and Brk protein expressions were not associated with age, tumor diameter, and histological grade (P>0.05),were associated with lymph node metastasis and TNM stage (P<0.05). The VEGF protein expression was not associated with age and tumor diameter (P>0.05), but was associated with histological grade, lymph node metastasis, and TNM staging (P<0.05). ③ In the breast cancer tissue, OPN, Brk, and VEGF had positive correlation with each other (P<0.05), but not in the adjacent (2cm) normal breast tissue and the distal (>5 cm) normal breast tissue (P>0.05). Conclusions The expressions of OPN and Brk from the same signal pathway increase by turns in the distal (>5 cm) normal breast tissue, adjacent (2cm) normal breast tissue, and breast cancer tissue. OPN induced the adhesion and migration of endothelial cells to accelerate vascular repair through VEGF and Brk has correlation with the progress of tumor invasion and metastasis through participating in tumor vascularization.

        • The effects of physiotherapy on pulmonary function in COPD patients with primary lung cancer undergoing lung resection

          Objective To assess the effects of physiotherapy on pulmonary function in COPD patients with lung cancer after lobectomy or pneumonectomy. Methods Fifty-five COPD patients with lung cancer undergoing lobectomy or pneumonectomy from January 2005 to May 2014 were recruited in the study. They were divided into group A received comprehensive physiotherapy before surgery and group B without comprehensive physiotherapy before surgery. The changes of lung function and tolerance were compared before physiotherapy (T1 time point) and after physiotherapy (T2 time point) in the group A, and between two groups before lung resection (T2 time point) and after lung resection (T3 time point). Results In group A, the forced expiratory volume in one second (FEV1), vital capacity (VC), peak expiratory flow at 50% of vital capacity (FEF50) and FEF25 increased significantly respectively by 16.96%, 14.75%, 20.69% and 13.79% compared with those before physiotherapy. Meanwhile, six-minutes walking distance (6MWD) achieved a significant improvement. After resection of lung, FEV1 and VC appeared to reduce, and pulmonary small airway function, tolerance, and clinical features deteriorated significantly. The differences between T2 and T1 in FEV1, FEF50 and FEF25 in the patients with FEV1%pred ≥80% and 50%-80% were similar with those in the patients with FEV1%pred<50%. The differences between T2 and T3 in FEF50 and FEF25 in the patients with FEV1%pred≥80% and 50%-80% were higher than those with FEV1%pred<50%. For the patients with lobectomy, FEV1 and VC in the group B were lower than those in the group A (FEV1: 10.24% vs. 22.44%; VC: 10.13% vs. 20.87%). For the patients with pulmonary resection, FEV1 and VC had little differences (FEV1: 36.33% vs. 36.78%; VC: 37.23% vs. 38.98%). Conclusion Physiotherapy is very important for the preoperative treatment and postoperative nursing of COPD patients with primary lung cancer.

        • Efficacy and safety of selective surgery after colonic stenting versus emergency surgery foracute obstructive colorectal cancer: a meta-analysis

          ObjectiveThe aim of this current meta-analysis is to evaluate the efficacy and safety of selective surgery after colonic stenting versus emergency surgery for acute obstructive colorectal cancer.MethodsThe studies published from January 1, 2000 to July 31, 2018 were searched from Pubmed, Embase, Cochrane Library, CNKI, Wanfang database, and VIP database. RevMan 5.3 software was used for data analysis.ResultsA total of 21 studies were included in this meta-analysis. Compared to emergency surgery, selective surgery after colonic stenting had significant lower mortality rate [OR=0.44, 95% CI was (0.26, 0.73), P<0.05], permanent stoma rate [OR=0.46, 95% CI was (0.23, 0.94), P<0.05], complication rate [OR=0.47, 95% CI was (0.35, 0.63), P<0.05], and wound infection rate [OR=0.40, 95% CI was (0.25, 0.65), P<0.05)], but had significant higher primary anastomosis rate [OR=3.30, 95% CI was (2.47, 4.41), P<0.05] and laparoscopic surgery rate [OR=12.55, 95% CI was (3.64, 43.25), P<0.05]. But there was no significant differences between the two groups as to anastomotic leak rate [OR=0.86, 95% CI was (0.48, 1.55), P>0.05].ConclusionsSelective surgery after colonic stenting can be identified in a reduced incidence of mortality rate, complication rate, permanent stoma rate, and wound infection rate, and also can increase primary anastomosis rate and laparoscopic surgery rate. Thus, for acute obstructive colorectal cancer, selective surgery after colonic stenting is better than emergency surgery.

        • Expression and clinical value of LncRNA NNT-AS1 and MNX1-AS1 in lung cancer patients

          Objective To investigate the expression and clinical value of long chain non-coding RNA nicotinamide nucleotide hydrogenase antisense RNA1 (LncRNA NNT-AS1), motor neuron and pancreas homeobox protein 1 antisense RNA1 (MNX1-AS1) in lung cancer patients. Methods This study selected 128 patients diagnosed with lung cancer admitted to The Third Medical Center of the General Hospital of the People’s Liberation Army from April 2020 to April 2021 as a cancer group. During the same period, 128 patients with benign pulmonary nodules were regarded as a benign group, and 128 healthy individuals who underwent physical examination were selected as a control group. Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the levels of LncRNA NNT-AS1 and MNX1-AS1 in serum. A three-year follow-up was conducted on all lung cancer patients, with 52 patients in the death group and 76 patients in the survival group. Receiver operator characteristic (ROC) curve was applied to analyze the diagnostic value of serum LncRNA NNT-AS1 and MNX1-AS1 for the occurrence of lung cancer and their predictive value for prognosis. Results Compared with the control group, the serum levels of LncRNA NNT-AS1 and MNX1-AS1 were obviously increased in the benign group and the cancer group (P<0.05). Compared with the benign group, the levels of LncRNA NNT-AS1 and MNX1-AS1 in serum of the cancer patients were obviously increased (P<0.05). The area under ROC curve (AUC) of serum LncRNA NNT-AS1 combined with MNX1-AS1 for the diagnosis of lung cancer was higher than that of LncRNA NNT-AS1 and MNX1-AS1 alone (ZLncRNA NNT-AS1~LncRNA NNT-AS1+MNX1-AS1=2.496, P=0.013; ZMNX1-AS1~LncRNA NNT-AS1+MNX1-AS1=2.831, P=0.007). The levels of LncRNA NNT-AS1 and MNX1-AS1 were related to tumor differentiation, clinical stage, and lymph node metastasis (P<0.05). Compared with the survival group, the serum levels of LncRNA NNT-AS1 and MNX1-AS1 in the death group were obviously increased (P<0.05). The AUC of combined prediction for lung cancer prognosis by serum LncRNA NNT-AS1 and MNX1-AS1 was higher than that predicted by LncRNA NNT-AS1 and MNX1-AS1 alone (ZLncRNA NNT-AS1~LncRNA NNT-AS1+MNX1-AS1=2.539, P=0.011; ZMNX1-AS1~LncRNA NNT-AS1+MNX1-AS1=3.377, P=0.001). Conclusion LncRNA NNT-AS1 and MNX1-AS1 are highly expressed in serum of lung cancer patients, and both have certain value in diagnosis and prognosis evaluation of lung cancer.

        • Safety and clinical outcomes of thoracoscopic segmentectomy in bilateral lung cancer: A single-center retrospective study

          Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. MethodsWe retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.

Methods : Enrolled consecutive rectal cancer patients undergoing curative surgery were evaluated by MSCT scan. Meanwhile venous blood specimens were taken to measure preoperative SAA concentration. Both MSCT staging and MSCT plus SAA staging were performed to compare with each other. Results : The study population consisted of 121 patients. The accuracy of T staging was 851% for MSCT. The accuracy in evaluating lymph nodes metastases was 760% for MSCT plus SAA compared with 595% for MSCT alone (〖WTBX〗P lt;0001). All the distant metastases were correctly detected by MSCT. The method combining MSCT with SAA led to significant improvement on preoperative TNM staging compared with MSCT alone (785% vs. 636%, 〖WTBX〗P =0011). Conclusion : MSCT plus SAA showed greater accuracy than MSCT alone in rectal cancer staging and lymph node metastases. This novel strategy of preoperative evaluation appears to provide more accurate information on tumor progression and preoperative therapy decisionmaking.

        • Multi-disciplinary team treatment for a case of primary giant liver cancer

          ObjectiveThe present study was to investigate the value of multi-disciplinary team (MDT) model in patient with primary giant liver cancer.MethodsThe MDT model was carried out for a BCLC B stage patient who admitted in the Second Affiliated Hospital of Chongqing Medical University in July 2018. The associated references were reviewed and the treatment methods were discussed about primary giant liver cancer.ResultsAn elder man who was diagnosed as primary hepatocellular carcinoma (minor cancer) in right lobe of the liver in three years ago and took Chinese medicine orally. When the patient subsequent visited this time, the liver cancer increased about 10 cm. After discussed by MDT, the treatment method was draw up to transarterial chemoembolization (TACE) plus surgery. After received twice TACE therapies in the later 14 weeks, the tumor in right lobe had significantly shrinked and left lobe enlarged. The patient underwent laparoscopic right liver hepatectomy after the second MDT discussion in 5 months later. The patient underwent operation successfully. The operation lasted for 270 minutes, and the intraoperative blood loss was about 500 mL. The suspended red blood cells (400 mL) was infused. The patient underwent transient liver failure and recovered through hepatoprotective and symptomatic supportive treatment, and discharged on 12 days after operation. A retrospective examination of abdominal CT at 4 months postoperatively revealed a significant hyperplasia of the left lobe of the liver, and there was no sign of recurrent tumor. The patient was continue to followed up.ConclusionsThepatient with primary giant hepatocellular carcinoma who cannot underwent surgery at the first time can received TACE, and a few patients could be underwent radical operation later. MDT should be applied flexibly in the treatment of patients with huge hepatocellular carcinoma from beginning to end, so the best treatment plan should be carried out for patients.

        • Single Utility Port Video-assisted Thoracoscopic Surgery Lobectomy for Patients with Early-stage Peripheral Non-small Cell Lung Cancer

          ObjectiveTo evaluate clinical outcomes of single utility port video-assisted thoracoscopic surgery (VATS) lobectomy for patients with early-stage peripheral non-small cell lung cancer. MethodsWe retrospectively analyzed the clinical data of 46 consecutive patients with early-stage peripheral non-small cell lung cancer who underwent single utility port complete VATS lobectomy in the First Affiliated Hospital of Hebei north University from December 2012 through November 2014. There were 39 male patients and 7 female patients with their age of 42-76 (60.26±4.38) years (VATS group). There were 58 patients with early-stage peripheral non-small cell lung cancer who underwent lobectomy via traditional thoracotomy including 47 male and 11 female patients with their age of 44-73 (61.42±3.67) years for the same period (conventional thoracotomy group). Clinical outcomes were compared between the two groups. ResultsAll the operations were successful. There was no conversions during single utility port VATS lobectomy, and no periopera-tive death in both groups. The VATS group had significantly less blood loss (126.10±48.56 ml vs. 260.84±69.70 ml), and amount of thoracic drainage (230.52±50.22 ml vs. 380.16±96.24 ml, P<0.05). Hospital stay was significantly shorter in the VATS group than the conventional thoracotomy group (6.42±1.40 days vs. 9.64±2.08 days, P<0.05). However, there was no significant difference between the VATS group and the conventional thoracotomy group with regard to the opera-ting time (146.25±19.68 minutes vs. 139.26±25.39 minutes), number of lymph nodes procured (13.56±2.31 vs. 14.12±3.06), and postoperative complications (13.0% vs. 19.0%, P>0.05). ConclusionSingle utility port VATS lobectomy for patients with early-stage peripheral non-small cell lung cancer is technically feasible, with less blood loss and shorter hospital stays for achieving acceptable standards of lymph node dissection. It is a promising surgical procedures for patients with early-stage peripheral non-small cell lung cancer.
