ABSTRACT
Objective:To analyze the invasion characteristics and prognostic factors of patients with Masaoka-Koga stage Ⅲ thymoma.Methods:The tumor invasion characteristics of 179 patients who were diagnosed with Masaoka-Koga stage Ⅲ thymoma and treated in Affiliated Cancer Hospital of Zhengzhou University from January 2000 to June 2018 were analyzed retrospectively. According to the treatment methods, all patients were divided into the radical operation group ( n=94), palliative operation group ( n=39) and simple biopsy group ( n=46). The χ2 test was used to compare the classified variables, Kaplan- Meier method was utilized to calculate the cumulative survival rate, log-rank method was used for group comparison and univariate analysis, and Cox’s regression model was used for multivariate analysis. Results:Mediastinal pleural invasion (86.0%) was the most common site, followed by pericardium (50.8%), great vessel (40.8%) and lung (36.3%). The proportion of macrovascular invasion in the radical operation group was 14.9%, significantly lower than 79.5% and 60.9% in the palliative surgery group and biopsy group (both P<0.001). Multivariate analysis showed that the nature of operation ( P<0.001), age ( P=0.011), radiotherapy ( P=0.020) were the independent factors affecting overall survival (OS), while nature of operation ( P<0.001), age ( P=0.004), radiotherapy ( P=0.020), number of invasive organs ( P=0.023) and pathological type ( P=0.016) were the independent factors affecting progress-free survival (PFS). Conclusions:For patients with Masaoka-Koga stage Ⅲ thymoma, mediastinal pleura is the most common site of invasion, pericardium, lung and great vessels are also commonly invaded. The invasion of mediastinal pleura, pericardium and lung exerts slight effect on surgical resectability, whereas great vessel involvement can significantly affect surgical resectability. OS and PFS in patients undergoing radical resection are significantly better than those in patients treated with palliative resection and biopsy. Radical resection is the most important factor affecting prognosis.
ABSTRACT
Objective:To evaluate the long-term survival and identify prognostic factors of patients diagnosed with early-stage non-small cell lung cancer (ES-NSCLC) receiving stereotactic ablation radiotherapy (SABR).Methods:Clinical data of 109 ES-NSCLC patients treated with SABR in Henan Cancer Hospital from 2011 to 2018 were retrospectively analyzed. The overall survival (OS), cancer-specific survival (CSS) and progression-free survival (PFS) were calculated by Kaplan- Meier method and log-rank test. Multivariate prognostic analysis was performed by Cox regression model. Results:The median follow-up time was 44 months (2-93 months). The median OS, CSS and PFS were 78 months, 78 months and 44 months, respectively. The 1-year OS, CSS and PFS were 95.4%, 97.2% and 84.1%, and 75.6%, 79.1% and 56.6% for the 3-year OS, CSS and PFS, and 55.6%, 60.7% and 37.3% for the 5-year OS, CSS and PFS, respectively. Univariate analysis showed that ECOG score, age, smoking history and derived-neutrophil/lymphocyte ratio (dNLR) were the influencing factors of OS ( P=0.03, 0.02, 0.04, 0.001). Age, smoking history and dNLR were the influencing factors of CSS ( P=0.02, 0.03, 0.001). Multivariate analysis demonstrated that dNLR was an independent prognostic factor for OS and CSS ( P=0.001, 0.001). Conclusions:ES-NSCLC patients treated with SABR can achieve favorable survival. The dNLR is an independent prognostic factor of OS and CSS, which can be considered in clinical application.
ABSTRACT
Objective:To investigate the clinical effect of low molecular weight heparin sodium combined with antivenin in the treatment of severe and critical bite by Trimeresurus stejnegeri.Methods:The clinical data of 48 patients with severe or critical bite by Trimeresurus stejnegeri admitted to emergency department of Southeast Hospital Affiliated to Xiamen University from March 2017 to May 2019 were retrospectively analyzed. On the basis of early treatment of antivenom serum, internal administration and external application of Jidesheng snake tablet, and wound incision and detoxification, the patients were divided into heparin treatment group and non-heparin treatment group according to whether the low molecular heparin sodium was used or not. The patients in the two groups were compared in terms of gender, age, clinical classification, swelling degree of injured limbs, change of coagulation function index, bleeding of skin, mucous membrane or digestive tract, blood transfusion, local symptoms of bite, length of hospital stay and prognosis.Results:There was no significant difference in terms of gender, age, clinical classification or swelling degree of injured limbs between the two groups. On the 3rd day of treatment, the platelet count (PLT) in the heparin treatment group was significantly higher than that in the non-heparin treatment group [×10 9/L: 210.0 (160.0, 252.0) vs. 136.0 (104.0, 198.5), P < 0.05]. However, there was no significant difference in the four coagulation test results between the two groups. On the 6th day of treatment, the plasma thrombin time (TT) in the heparin treatment group was significantly shorter than that on the 3rd day of treatment [s: 30.3 (20.4, 37.0) vs. 34.7 (24.0, 73.4), P < 0.05], and the fibrinogen (FIB) in the heparin treatment group was significantly higher than that in the non-heparin treatment group [g/L: 0.60 (0.31, 1.07) vs. 0.20 (0.14, 0.60), P < 0.01]. The incidence of bleeding in the heparin treatment group was significantly lower than that in the non-heparin treatment group [21.7% (5/23) vs. 64.0% (16/25), P < 0.01]; 11 patients in the heparin treatment group and 18 patients in the non-heparin treatment group received blood transfusion and prothrombin complex supplement respectively. There was no significant difference in the length of hospital stay between the heparin group and non-heparin treatment group (days: 6.91±1.92 vs. 7.48±2.27, P > 0.05). The patients in both groups were followed up for 1 week to 1 month after treatment, and no death or local necrosis of skin and soft tissue was found. Conclusions:For the patients with severe and critical bite by Trimeresurus stejnegeri, on the basis of injection of antivenom serum, internal administration and external application of Jidesheng snake tablet, and wound incision and detoxification, early application of low molecular weight heparin sodium anticoagulation and other comprehensive treatment is helpful to improve limb swelling and inflammation, reduce blood transfusion, promote the recovery of coagulation function, and shorten the length of hospitalization.
ABSTRACT
Objective To assess the clinical efficacy of vacuum sealing drainage (VSD) in the treatment of mixed poisonous snake bite. Methods A prospective study was conducted. Forty-three snake bite patients by mixed poisonous snakes admitted to Department of Emergency of the 175th Hospital of People's Liberation Army from February 2015 to February 2017 were enrolled. All patients were divided into routine treatment group (n = 20) and VSD treatment group (n = 23) according to whether early incision decompression and using the VSD technique. The patients in the routine treatment group were treated with injection of antivenoms, Jidesheng snake tablets external coating, and wound incision detoxification. Beside the routine treatments, patients in the VSD treatment group were treated with incision decompression and the VSD suction aspiration for the swelling limb. Bite wound infection rate, local skin necrosis area, maximum level of C-reactive protein (CRP), length of hospital stay and disability rate were compared between the two groups. Results Forty-three patients were followed up for 6-12 months with average of (10.3±1.4) months postoperatively. There were no deaths in both groups. Compared with the routine treatment group, wound infection rate in the VSD treatment group was significantly lowered [8.7% (2/23) vs. 40.0% (8/20)], local skin necrosis area was significantly reduced (cm2: 4.2±0.8 vs. 6.0±1.3), the maximum CRP was significantly lowered (mg/L: 50.0±12.1 vs. 68.0±13.4), the hospitalization time was significantly shortened (days: 11.7±2.9 vs. 17.7±4.9), and the difference above was statistically significant (all P < 0.05). The disability rate of the VSD treatment group was lowered as compared with routine treatment group [13.0% (3/23) vs. 13.0% (6/20)] without statistically significant difference. Conclusion Early incision decompression and VSD pressure suction of the swelling limb associated with combination therapy of drugs is a reliable and effective method for severe snakebite, and can promote physical rehabilitation and shorten hospital stay.

ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the clinical efficacy of YANG's pricking-cupping therapy for knee osteoar thritis (KOA). Methods This was a multi-center randomized parallel controlled trial. One hundred and seventy one patients with KOA were randomly allocated to a pricking-cupping group (89 cases) and a conventional acu puncture group (82 cases). Neixiyan (EX-LE 4), Dubi (ST 35) and ashi points were selected in the two groups. Patients in the pricking-cupping group were treated with YANG's pricking-cupping therapy; the seven-star needles were used to perform pricking at acupoints, then cupping was used until slight bleeding was observed. Patients in the conventional acupuncture group were treated with semi-standardized filiform needle therapy. The treatment was given for 4 weeks (from a minimum of 5 times to a maximum of 10 times). The follow-up visit was 4 weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the visual analogue scale (VAS) were adopted for the efficacy assessments.</p><p><b>RESULTS</b>The pain score, stiffness score, physical function score and total score of WOMAC were all reduced after 4-week treatment and during follow-up visit in the two groups (all P<0. 0001). Except that the difference of stiffness score between the two groups was not significant after 4-week treatment (P>0. 05), each score and total score of WOMAC in the pricking-cupping group were lower than those in the conventional acupuncture group after 4-week treatment and during follow-up visit (P<0. 0001, P<0. 01). After 2-week treatment, 4-week treatment and during follow-up visit, the VAS was all reduced compared with that before treatment (all P<0. 0001) ; with the increase of the treatment, the reducing trend of VAS was more significant (P<0. 0001). The scores of VAS in the pricking-cupping group were lower than those in the conventional acupuncture group after 4-week treatment and during follow-up visit (P < 0. 01, P <0. 0001). CONCLUSION The YANG's pricking-cupping and conventional acupuncture therapy can both significantly improve knee joint pain and function in patients with KOA, which are relatively safe. The pricking cupping therapy is superior to conventional acupuncture with the identical selection of acupoints.</p>

Objective The aim of this study was to investigate the co-operative role of HGF and IL-1ra in metastatic processes by interactions between colon cancer cells and stromal cells in their microenvironment.Methods Expression of IL-1α,HGF and c-Met mRNA and proteins were determined by RT-PCR and Western blot.The effect of HGF on metastatic potential was evaluated by proliferation,invasion,and angiogenesis assays using an in vitro system consisting of co-cultured tumor cells and stromal cells.Results IL-1α expression was closely correlated with metastatic potential,and cancer cell-derived IL-1α significantly promoted HGF expression by fibroblasts (P ＜ 0.01).HGF enhanced the migration and proliferation of human umbilical vein endothelial cells (HUVECs),and angiogenesis (P ＜ 0.01).The high liver-metastatic colon cancer cell line (HT-29),which secretes IL-1 α,significantly enhanced angiogenesis compared to the low liver-metastatic cell line (CaCo-2),which does not produce IL-1 α (P ＜ 0.01).IL-1 ra significantly inhibit migration,proliferation and angiogenesis (P ＜ 0.01).Conclusions Autocrine IL-1α and paracrine HGF enhance the metastatic potential of colon cancer cells;IL-1ra inhibit the metastatic potential of colon cancer cells by blocking IL-1α and HGF signaling pathways.
ABSTRACT
Highly conjugated linear molecular wires are one of the basic elements for constructing molecular electronic devices. Among these conjugated compounds, ferrocene-terminated compounds as well as their derivatives have been widely studied because of their ideal electrochemical activity. Based on these, a new ferrocene-terminated phenylethynyaniline ( Fc-NH2 ) was synthesized by Sonogashira cross coupling reaction. The structure of the target compound was identified by infrared ( IR) , nuclear magnetic resonance ( NMR) , mass spectra ( MS) and cyclic voltammetry ( CV) . Combined the graphene-chitosan ( GH-CS) and Fc-NH2 , a new composite of GH-CS/Fc-NH2 was prepared and then used for immobilization of Cytc to prepare the GH-CS/Fc-NH2/Cytc/GCE. It was found from the CV result that a pair of peaks near-0. 2 V appeared which can be attributed to Cytc. The GH-CS/Fc-NH2/Cytc modified GCE showed good catalysis towards NaNO2 , and good linear relationship was found in the range of 1 ×10-7-1. 5 ×10-4 mol/L,and the determination limit was bellow 4×10-8 mol/L. Therefore, cytochrome c (Cytc) can be immobilized on the GH-CS/Fc-NH2 and the direct electron transfer can be realized between the electrode and solution and shows good prospect for detection of NaNO2 .
ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of colon cancer cell-derived interleukin-1α on the migration and proliferation of human umbilical vein endothelial cells as well as the role of IL-1α and IL-1ra in the angiogenesis process.</p><p><b>METHODS</b>Western blot was used to detect the expression of IL-1α and IL-1R1 protein in the colon cancer cell lines with different liver metastatic potential. We also examined how IL-1α and IL-1ra influence the proliferation and migration of umbilical vascular endothelial cells assessed by PreMix WST-1 assay and migration assay, respectively. Double layer culture technique was used to detect the effect of IL-1α on the proliferation and migration of vascular endothelial cells and the effect of IL-1ra on the vascular endothelial cells.</p><p><b>RESULTS</b>Western blot analysis showed that IL-1α protein was only detected in highly metastatic colon cancer HT-29 and WiDr cells, but not in the lowly metastatic CaCo-2 and CoLo320 cells.Migration assay showed that there were significant differences in the number of penetrated cells between the control (17.9±3.6) and 1 ng/ml rIL-1α group (23.2±4.2), 10 ng/ml rIL-1α group (31.7±4.5), and 100 ng/ml rIL-1α group (38.6±4.9), showing that it was positively correlated with the increasing concentration of rIL-1α (P<0.01 for all). The proliferation assay showed that the absorbance values were 1.37±0.18 in the control group, and 1.79±0.14 in the 1 ng/ml rIL-1α group, 2.14±0.17 in the 10 ng/ml rIL-1α group, and 2.21±0.23 in the 100 ng/ml rIL-1α group, showing a positive correlation with the increasing concentration of rIL-1α(P<0.01 for all). IL-1ra significantly inhibited the proliferation and migration of vascular endothelial cells (P<0.01). The levels of VEGF protein were (1.697±0.072) ng/ml, (3.507±0.064)ng/ml and (4.139±0.039)ng/ml in the control, HUVECs+ IL-1α and HUVECs+ HT-29 co-culture system groups, respectively, showing a significant difference between the control and HUVECs+ 10 pg/ml rIL-1α groups and between the control and HUVECs+ HT-29 groups (P<0.01 for both).</p><p><b>CONCLUSIONS</b>Our findings indicate that colon cancer cell-derived IL-1α plays an important role in the liver metastasis of colon cancer through increased VEGF level of the colon cancer cells and enhanced vascular endothelial cells proliferation, migration and angiogenesis, while IL-1ra can suppress the effect of IL-1α and inhibit the angiogenesis in colon cancer.</p>

ABSTRACT
Objective To investigate the effect of chemotherapy combined with amino acid on quality of life(QOL)in elderly patients with non-small cell lung cancer(NSCLC). Methods Seventy-four elderly patients with NSCLC were divided randomly into experimental group and control group.The same NP(cisplatin+vinorelbine)chemotherapy was carried out in all the 2 groups for 3 cycles.Except of chemotherapy,experimental group were treated with amino acid 500 ml/d in the same time,while control group recieved chemotherapy only.After 3 monthes,the QOL was analyzed using Chinese Version of European Organization for Researeh and Treatment of Cancer(EORTC)core questionnaire(QLQ-C30)and specific lung cancer module QLQ-LC13,and therapeutic effectiveness was evaluated according to WHO standard as well. Results After chemotherapy,the body function,mood function,social function were better in experimental group than in control group(all P＜0.05),the effective rate was 87.8%,83.8%and 77.0%in experimental group;77.0%,45.9%and 45.9%in control group.Insomnia(8.1%),suppressed appetite(5.4%),weary(47.3%)were less serious in experimental group than in control group(17.6%,17.6%and 59.5%)(all P＜0.05).The primary symptoms were cough,emptysis,thoracalgia and dyspnoea in both 2 groups before chemotherapy.All the symptoms were alleviated after chemotherapy.Some patients have side effects such as tongue pain,alopecie,hand and foot tingle.But the number of patients with tongue pain was less in experimental group(8.3%)than in control group(18.4%).The chemotherapy effect had no difference by the WHO standard. Conclusions The QOL of elderly patients with NSCLC can be improved by chemotherapy combined with amino acid treatment,and the treatment with amino acid 500 ml/d is safety.
ABSTRACT
Objective To evaluate the effects of δ-aminolaevulinic acid-photodynamic therapy (ALA-PDT) in the treatment of primary carcinomas on the facial skin. Methods In the accordance of these tumors' sites and morphology, 14 patients with squamous cell carcinoma (SCC), 38 patients with basal cell carcinoma (BCC) and 5 patients with Bowen disease were given four to eight times of topical ALA followed by PDT. Results Ten (71.4%) SCC cases, 34 (89.5%) BCC cases and all (100%) Bowen disease cases completely recovered after ALA-PDT. The others all obtained signifi-cant improvement after final treatment. Their unaffected tissues around these tumors kept well and no scaring appeared after ALA-PDT. The recurrence rates among the completely-recovered cases were 10.0% (SCC), 11.8% (BCC) and 0% (Bowen disease), respectively, by the end of six-month's follow-up. Conclusions Topical ALA-PDT is an effective new therapeutical method with lower recur-rence rates, fewer side effects, no scar formation and excellent cosmetic results for primary carcinomas localizing on the facial skin.
ABSTRACT
AIM:To observe the effects of prostaglandin E2 receptor1 (EP1) in neuronal cell death induced by hypoxia/reoxygenation and ischemia/reperfusion. METHODS:The cortical neurocytes of neonatal Wistar rats were cultured for 12 days and exposed to hypoxia/re-oxygenation to establish a hypoxia/re-oxygenation model. Another set of cultured primary neonatal cortical neurocytes of rats were pretreated with 17-pt (an antagonist of EP1),then underwent hypoxia for 3 h,re-oxygenated for 21 h. MTT reagent was added 1 h before measuring the cell viability. Neuron apoptosis was determined by flow cytometry. The protein expression was examined by Western blotting. RESULTS:Compared to the control cells (only underwent hypoxia /re -oxygenation and without any pretreatment),the neurons pretreated with 17-pt and then underwent hypoxia/re-oxygenation showed significantly lower survival rate (P
