Lung squamous cell carcinoma with intratracheal diffuse leukoplakia as the main manifestation is very rare in clinic. The clinical data of a patient with pulmonary squamous cell carcinoma with intratracheal diffuse leukoplakia admitted to the Affiliated Hospital of Jining Medical University in December 25, 2021 were retrospectively analyzed in order to improve the understanding of this special manifestation. The patient was a 73-year-old male with clinical manifestations of cough, sputum, and blood-stained sputum. Chest CT indicated patchy high-density shadow on the upper right lung, whole-course thickening of trachea and bronchial walls, and bronchoscopy showed diffuse trachea-bronchial mucosa congestion and edema, with a large number of leukoplakia on the surface. The clinical effect was stable after 2 cycles of chemotherapy. Lung squamous cell carcinoma accompanied by diffuse leukoplakia in the trachea is a rare presentation. Chest CT can show thickening of the tracheal and bronchial wall, while the lesion and tumor signs of the primary lesion are not obvious. Electronic bronchoscopy as soon as possible can avoid missed diagnosis.

Hepatocellular carcinoma (HCC) is a common malignant tumor with poor prognosis and high mortality. In this study, we demonstrated a novel vaccine targeting HCC and tumor neovascular endothelial cells by fusing recombinant MHCC97H cells expressing porcine α-1,3-galactose epitopes (αGal) and endorphin extracellular domains (END) with dendritic cells (DCs) from healthy volunteers. END⁺/Gal⁺-MHCC97H/DC fusion cells induced cytotoxic T lymphocytes (CTLs) and secretion of interferon-gamma (IFN-γ). CTLs targeted cells expressing αGal and END and tumor angiogenesis. The fused cell vaccine can effectively inhibit tumor growth and prolong the survival time of human hepatoma mice, indicating the high clinical potential of this new cell based vaccine.

Objective To explore the impact of oral nutritional supplements in the local advanced nasopharyngeal carcinoma patients receiving chemoradiotherapy. Methods From 2016 to 2018, we prospectively collected 114 patients into our study, including intervention group ( n=58) and control group ( n=56) . Patients in the intervention group were given oral nutritional supplements from the beginning of radiotherapy, while the control group patients were receiving usual diet care. We collected data of weight, hematological index and nutrition related information before, during and after treatments. Results All patients experienced weight loss during radiotherapy. The declining trend was more obvious in intervention group but with no statistical difference ( P>0.05) . Radiotherapy interruption was lower, completion rate of 2 cycles of concurrent chemotherapy was higher( 78% vs 64%, P=0.02) and level of total serum protein and albumin was more stable ( P=0.003, 0.001) in the intervention group. No difference was found in acute toxicities between the two groups ( P>0.05) . During the treatment period, the nutrition risk screening score declined, more patients with NRS 2002 ≥3 in the control group than the intervention group ( P<0.05) , while no statistically significant difference was found in PG-SGA between the two groups ( P>0.05 ) . Conclusions Oral nutritional supplements can improve treatment tolerance and keep the stability of serum protein level, nevertheless, it has no obvious advantage in maintenance of weight and short-term nutritional status

Objective The aim of the present study was to evaluate the efficacy of three different modalities in treatment of lung oligometastases from nasopharyngeal carcinoma ( NPC) after radiotherapy and to identify a more appropriate treatment modality.Methods The clinical data of 87 cases of lung oligometastases from NPC were analyzed retrospectively.Among them, 33 patients underwent local small-field irradiation+/-chemotherapy, 28 underwent whole-lung irradiation+chemotherapy, and 26 underwent simple chemotherapy.The survival rates were calculated using Kaplan-Meier analysis.The differences among the modalities were evaluated using the log-rank test.Cox univariate and multivariate analyses were performed to determine the influencing factors.Results The 3-year lung metastasis survival ( LMS) rates of patients with lung metastasis undergoing the three treatment modalities ( local small-field irradiation +/-chemotherapy, whole-lung irradiation+chemotherapy and chemotherapy alone) were 89.3%, 72.7%, and 72.4%, respectively, showing a significant difference between the groups ( P=0.003 ) .Further subgroup analysis showed that the 5-year LMS rate was significantly higher in the local small-field irradiation+/-chemotherapy group than that in the whole-lung irradiation+chemotherapy group and chemotherapy alone group (P=0.001).The 2y-ear progression -free survival (PFS ) rates of the three groups were 571.%, 25.8%and 3.8%, respectively, showing significant intergroup differences ( P=0.002 and P<0 .001 ) . Multivariate analysis indicated that compared with the whole lung irradiation group and the chemotherapy alone group, the local irradiation+/-chemotherapy is an independent favorable prognostic factor for LMS and PFS (P<0.05). Conclusion Local radiotherapy combined with systemic chemotherapy is the best therapeutic modality for lung oligometastases derived from NPC after radiotherapy, improving the LMS and prolonging the PFS.

Circulating microRNAs (miRNAs) is a class of non-coding small RNA molecules.As tumor biomarkers, circulating miRNAs deregulation is associated with the initiation and progression of human cancer.Studies indicate that circulating miRNAs have great potential in the early diagnosis and prognosis of primary or metastatic tumors (colorectal, breast, prostate, hepatocellular and ovarian cancer and other epithelial cancer).

OBJECTIVETo explore the relationship between positive lymph node number, involved region, positive lymph node ratio and the prognosis of patients with hypopharyngeal cancer.

METHODSClinicopatological data of 81 patients with hypopharyngeal squamous cell carcinoma who underwent hypopharyngectomy and cervical lymph node dissection from January 2000 to December 2005 in our hospital were analyzed retrospectively. The relationship between positive lymph node number, involved region, positive lymph node ratio and the prognosis was analyzed.

RESULTSThe rate of lymph node metastasis was 79.0% (64/81) in the 81 patients with hypopharyngeal cancer. Of which, the rates of unilateral metastasis and bilateral metastasis were 82.9% (53/64) and 17.1% (11/64), respectively. The rate of lymph node metastasis was increasing with advancing tumor stage. The median survival times were 81, 51 and 26 months in the patients with 0, 1-3 and ≥ 4 positive lymph nodes, respectively (P < 0.001), 84, 45 and 23 months in patients with 0, 1-2 and ≥ 3 involved regions, respectively (P < 0.001), and 84, 51 and 17 months in patients with positive lymph node ratio of 0, <10% and ≥ 10%, respectively (P < 0.001). Multivariable analysis showed that positive lymph node ratio, extracapsular infiltration, T classification and treatment modality were independent prognostic factors (P = 0.002).

CONCLUSIONSPositive lymph node ratio is an independent prognostic factor for hypopharyngeal cancer.

Objective To investigate the effect of vitamin D on pulmonary function in patients with chronic obstructive pulmona-ry disease,and to explore its possible mechanism.Methods Patients with chronic obstructive pulmonary disease admitted in the hospital were randomly divided into 2 groups,one group of patients were given regular COPD treatment (control group,30 cases), the other group of patients were given vitamin D on the basis of conventional therapy(experimental group,30 cases).Pulmonary function test and C reaction protein (CRP)determination in the 2 groups were performed,the contents of PaO2 ,PaCO2 were also determined.Results Compared with the control group,lung function improvement in experimental group were more obvious,and the the number of acute attack significantly reduced(P <0.05).The concentration of CRP in experimental group was significantly lower after treatment than before treatment(P <0.05),while the concentration of CRP in control group didn′t change significantly (P >0.05).Conclusion Vitamin D contributes to the improvement of pulmonary function in patients with COPD,and its mecha-nism might relate to the reduction of inflammatory reaction.

Objective To investigate left ventricular (LV) strain in patients with hypertension (HT)and myocardial hypertrophy using three-dimensional speckle tracking echocardiography.Methods Myocardial movement was analyzed in 37 primary HT patients with myocardial hypertrophy and 27 healthy volunteers.LV longitudinal,circumferential,radial and area strains were measured.The correlation between each global strain parameter and LV ejection fraction (LVEF) was analyzed.Results LV global longitudinal strain(GSL),global radial strain (GSR) and global area strain (GSA) of HT patients with myocardial hypertrophy were significantly lower than the contrast group,whereas global circumferential strain(GSC) showed no significant difference between the two groups.Longitudinal,radial and area strains were decreased in LV basal and middle levels,while decreased circumferential strain was detected only in basal level.There were significant correlations between LVEF and GSL,GSC,GSR,GSA.Conclusions Impairment of LV regional myocardial contractility can be detected by three-dimensional speckle tracking echocardiography.
