ABSTRACT
Objective To evaluate the value of the systemic immune-inflammatory index (SII), CEA, Cyfra21-1, and NSE in predicting and diagnosing bone metastasis of lung cancer. Methods The clinical data of 618 patients with lung cancer were retrospectively analyzed. According to the bone metastasis at baseline, the data of the diagnosis group (patients with bone metastasis at baseline and patients without bone metastasis during follow-up) and the prediction group (patients with bone metastasis during follow-up and patients without bone metastasis during follow-up) were analyzed to determine the correlation between the above indicators and lung cancer bone metastasis. Results Predictive group: SII≥850 and NSE≥58.64 ng/ml were independent risk factors and independent predictors for lung cancer bone metastasis. The AUC of the combined SII+NSE model was 0.662, with a sensitivity of 54.5% and a specificity of 74.5%; it was superior to the predictive value of single factor (95%CI: 0.596-0.728; P < 0.001). Diagnostic group: lung adenocarcinoma, SII≥951.6, CEA≥5.14 ng/ml, NSE≥20.15 ng/ml, and Cyfra21-1≥3.94 ng/ml were independent risk factors for bone metastasis in lung cancer patients (P < 0.05). The AUC of SII alone in the diagnosis of lung cancer bone metastasis was 0.754. The AUC of the SII+Cyfra21-1 combined model was 0.82 which was the largest, with a sensitivity of 74% and a specificity of 78.5%; it was superior to any univariate AUC (P < 0.05). Conclusion The levels of SII, CEA, Cyfra21-1, and NSE in the bone metastasis group are significantly higher than those in the non-bone metastasis group. The predictive and diabnostic values would be improved further when SII combined with other single risk factors.
ABSTRACT
Multiple markers that related to gastric cancer has been widely used in clinical, to predict its occurrence, development and prognosis. Serum level of fibrinogen (FIB) and neutrophil to lymphocytes ratio (NLR) respectively as representative indicators of coagulation system and inflammation, can predict the prognosis of patients with gastric cancer and survival time. The rise of fibrinogen is associated with enhanced capacity of the gastric tumor cells proliferation, invasion and migration. High NLR is associated with significantly induced survival of patients with gastric cancer. The combination of fibrinogen and NLR (F-NLR) combines the advantages of each individual indicator in predicting the occurrence, development and prognosis of cancer. It has shown a great prognostic potential in gastric cancer, and can be widely applied in prospect.
ABSTRACT
Targeted therapy and immunotherapy are important methods for the treatment of metastatic melanoma, but monitoring the patient′s disease progress and treatment response during the treatment is the key to accurate treatment and personalized treatment.Circulating tumor DNA (ctDNA) as a non-invasive " liquid biopsy" method, due to its high sensitivity and specificity for gene mutations, and the advantages of being qualitative, quantitative and traceable, which has shown great application value in monitoring metastatic melanoma progression, evaluating efficacy, and predicting prognosis during targeted therapy and immuno-therapy.
ABSTRACT
Small cell lung cancer (SCLC)is an aggressive neuroendocrine carcinoma with a very high degree of malignancy. Currently,the standard treatment for SCLC is still chemoradiotherapy,and although SCLC is sensitive to chemotherapy in the early stage,recurrence and metastasis often occur due to drug resis-tance. In recent years,immunotherapy has made some progress in the study of SCLC. The immunodetection point programmed death-1 (PD-1)and its ligand (PD-L1)inhibitors,such as nivolumab,atezolizumab and pabolizumab,have shown good antitumor activity in clinical studies of SCLC,and PD-1 / PD-L1 inhibitors com-bined with chemotherapy have shown better efficacy,providing a new strategy for the treatment of SCLC.

ABSTRACT
Objective To detect the expression of osteopontin (OPN) in the pancreatic tissues of chronic pancreatitis (CP) rats,and analyze the relationship between the expression of OPN and pancreatic fibrosis.Methods A total of 20 male Wistar rats were randomly divided into control group and CP model group.Control group was treated by tail vein injection of absolute ethanol and glycerol,and CP model group received a single tail vein injection of dibutyltin dichloride (DBTC) to construct CP model.Six weeks after the procedure,the rats were sacrificed to obtain pancreatic tissue,and pathological examinations were routinely performed.Sirius-red staining was used to assess the degree of pancreatic fibrosis.The expression of OPN,α-SMA and Col I in the pancreas of CP rats was detected by immunohistochemistry and Western blot,and the relationship between the expression of OPN and the degree of fibrosis was analyzed.Results In CP model group,3 rats died.In the 7 rats which survived,light microscopic examination observed great proliferation of fibrous tissue in pancreatic interlobular space,vacuolization and necrosis of acinous cells,the infiltration of inflammatory cells in the pancreatic interlobular space and dilation of pancreatic duct.Results of Sirius-red staining showed that a large number of fresh red stripe and reticular collagen fibers were deposited in the interlobular space of the pancreatic tissues in the CP group,whereas there were only a few fiber deposited around the blood vessels and the pancreatic duct in the control group and the stained area in CP group (51 ± 11)％ was significantly larger than that of control group (9 ± 4)％ and the difference was statistically significant (P ＜ 0.01).The results of immunohistochemistry showed that the expression of OPN in CP group was strong positive in 3 rats and positive in 4 rats,which in control group was weak positive in 3 rats and negative in 7 rats.OPN expression in CP group was significantly higher than that in control group (Z =-5.170,P ＜ 0.01),and the expression of OPN was positively correlated with the Sirius-Red staining area (r =0.790,P ＜ 0.01).Western-blot results showed that the expression of OPN,α-SMA and Col I in CP group was significantly higher than that in control group (0.70 ±0.22 vs 0.24 ±0.11,0.71 ± 0.10 vs 0.06 ± 0.01,2.83 ± 1.42 vs 0.39 ± 0.07),and the differences were statistically significant (all P ＜ 0.05).Conclusions A single tail vein injection of DBTC can be used to successfully establish CP rat model.The expression of OPN is significantly increased in the CP group and is positively correlated with pancreatic fibrosis.
ABSTRACT
Circulating tumor DNA (ctDNA) refers to the DNA segment of the free tumor located in the peripheral circulation,which carries the biologic information derived from the tumor.In recent years,the innovation of the second generation sequencing technology has expanded the prospect of the clinical application of ctDNA analysis.Detection of ctDNA has made a great progress in the field of radiation therapy,especially in the aspect of evaluating the sensitivity of radiotherapy,ctDNA in peripheral blood is characterized by convenient extraction and high specificity.Detection of ctDNA is not only conducive to find minimal residual disease and metastasis,but also help clinicians better evaluate the curative effect and judge prognosis after radiotherapy,which will provide a new way of thinking for the diagnosis and treatment strategy of tumor.
ABSTRACT
Objective To observe the changes of expression levels of NMDA receptor NR2A and NR2B in anterior cingulate cortex (ACC) of chronic pancreatitis (CP) rats and explore its roles in the pathogenesis of pain in CP.Methods Male adult SD rats were randomly divided into CP group,control group and normal group using random number method.CP rat model was established by injecting 8mg/kg dibutyltin dichloride (DBTC) through tail vein.Control group was injected with a equal volume mixture of ethanol and glycerol via tail vein.After 4 weeks,yon Frey hair of different sizes (3.85,5.50,7.05,10.4,17.8 g) were used to stimulate the abdomen of the rats and the percentage of the positive pain response was recorded.Then the rats were sacrificed.The pancreas was collected for pathological examination.NR2A and NR2B subunit mRNA and protein expression in ACC was detected by realtime-PCR and Western Blotting,respectively.Results The success rate of CP model establishment was 60％.As Van Frey hair used to stimulate the rat abdomen increased from 3.85 g to 17.8 g,the percentage of positive pain response increased from (38.33 ±7.53)％ to(73.33±8.17)％ in CP group,from (7.80±6.70)％ to (34.44±5.27)％ in control group,from(6.57±5.48) ％ to(33.33 ± 5.00) ％ in normal group,which was increased with the increase of the stimulation intensity.For each stimulation intensity,the percentage of positive pain response in CP group was all obviously higher than those in control and normal group,and the differences were all statistically significant (all P ＜ 0.01),but there was no statistical difference between control group and normal group.The protein expression of NR2A of ACC in CP group,control group and normal group was 1.25 ± 0.78,0.95 ± 0.14 and 0.91 ± 0.09,respectively.The protein of NR2B in three groups were 1.44 ± 0.12,0.93 ± 0.08 and 0.94 ±0.04,respectively.NR2A and NR2B protein expressions in the CP group were both significantly higher than those in control group and normal group,and the difference was statistically significant (P＜0.01).The mRNA expression of NR2A in three groups were 1.43 ± 0.20,0.80 ± 0.10 and 1.01 ± 0.13,respectively.The mRNA expression of NR2B in three groups were 1.40 ± 0.09,0.98 ± 0.14 and 0.94 ± 0.05,respectively.The mRNA expressions of NR2A and NR2B in CP group were significantly higher than those in normal and control group,and the difference was statistically significant (P ＜0.01).Conclusions The expression of glutamate receptor NR2A and NR2B in ACC were upregulated in CP rats and may be involved in the development of the pain.
ABSTRACT
Objective To explore the role of the visceral afferent nerve hyperesthesia and acid-sensing ion channel 1 (ASIC1) in rats with reflux esophagitis (RE).Methods Sixty male Sprague-Dawley rats were selected and animal model was established.Rats were divided into control group (n=20) and RE group (n=40).The esophageal mocosa biopsy were routinely performed in two groups.The esophageal specific DRG neurons were identified by 1,1'dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate tracing method and the whole-cell patch clamp assay was performed.The expression of ASIC1 in esophageal mucosa and thoracic spine cord three to five segments at protein level and mRNA level were detected by Western blotting and quantitative real time-polymerase chain reaction (qPCR).Two independent samples t test was performed for statistical analysis.Results The body weight of RE group was significantly lower than that of control group ((179.41±-16.38) g vs (290.75 ±-22.20) g),and the difference was statistically significant (t=17.090,P＜ 0.01).Esophageal basal cell hyperplasia,papillary elongation,vascular dialation and congestion,inflammatory cells infiltration were found in RE group rats.The results of whole-cell patchclamp showed depolarization of the resting potential of esophageal-specific DRG neurons of RE group was more significant than that of control group (-(46.20 ± 1.92) mV vs-(51.60 ± 1.52) mV),and the difference was statistically significant (t=4.930,P＜0.01).The threshold current of RE group was much lower than that of control group ((18.00±13.04) pAvs (80.00±12.25) pA),and the difference was statistically significant (t=7.750,P＜0.01).When stimulated with two to three times the threshold current,the frequency of action potential of RE group significantly increased (5.80 ±1.48 vs 3.00 ±1.58,10.60±2.30 vs 5.20±1.92),and the differences were statistically significant (t=2.890 and 4.030,both P＜0.01).The results of Western blotting indicated that the expression of ASIC1 in esophageal mucosa of RE group was significatly lower than that of control group (0.614±0.120 vs 0.976±0.283),and the difference was statistically significant (t =2.885,P＜ 0.05),while there was no statistically significant difference in the expression of ASIC1 in DRG between RE group and control group (0.804 ± 0.182 vs 1.032±0.316;t=1.528,P＞0.05).The results of qPCR showed that the expression of ASIC1 mRNA in esophageal mucosa of RE group was lower than that of control group (0.694 ± 0.118 vs 1.036 ±0.137),and the difference was statistically significant (t=4.642,P＜0.01).However there was no statistically significant difference in ASIC1 at mRNA level between RE group and control group (1.002± 0.074 vs 0.985±0.120;t=0.294,P＞0.05).Conclusion The sensitivity of esophageal visceral afferent nerve of rats in RE group increases and ASIC1 may negatively regulate the formation of esophageal visceral hypersensitivity.

ABSTRACT
Objective To evaluate the adenoma detection rate( ADR)of fecal occult blood test (FOBT)-positive population in colorectal cancer screening programme and to analyse potential influence of“resection and discard”strategy on ADR. Methods Data of patients who paticipated in the Shanghai color-ectal cancer screening programme with FOBT-positive and received colonoscopy in the Digestive Endoscopic Center of Changhai Hospital from July 2013 to July 2014 were retrospectively analysed. ADR was calculated and compared by different genders. Multivariate logistic regression model was used to analyse the risk factors of polyp resection without retrieval. Results A total of 222 FOBT-positive patients were involved with 36. 5% male proportion. The total ADR was 19. 8%,higher in male(28. 4%)than in female(14. 9%)(P=0. 015). The independent risk factors of polyp resection without retrieval were diminutive polyp( OR =15. 256,95% CI:4. 159-55. 957),located in rectum( OR = 3. 663,95% CI:1. 427-9. 398) and polyp number >2(OR= 3. 988,95%CI:1. 562-10. 187).Conclusion ADR of FOBT-positive population is approx-imately 20%in our center. Low male proportion and“resection and discard”strategy may lead to lower ADR. ADR should be calculated by different genders and advanced endoscopic technology should be employed rou-tinely to predict the pathological diagonosis of the lesions.
ABSTRACT
Objective To investigate the role of p38 MAPK in the trypsin-induced injury in human esophageal epithelial cells.Methods Primary cultured human esophageal epithelial cells were stimulated with trypsin (20,40,and 80 μg/ml) for4 hours,phosphorylation of p38 MAPK was evaluated by Western blotting.Primary cultured human esophageal epithelial cells were stimulated with trypsin (40 μg/ml) and treated with p38 MAPK inhibitor (SB203580,1 and 10 μmol/L) simultaneously.Four hours later,the cells were collected for analysis.Results Western blotting results revealed that stimulation with trypsin enhanced phosphorylation of p38 MAPK,indicating that trypsin activated p38 MAPK in esophageal epithelial cells.SB203580 treatment suppressed trypsin-induced expression of pro-inflammatory cytokines including interleukin-8 (IL-8),cyclooxygenase 2 (COX2),and tumor necrosis factor alpha (TNFcα).Finally,SB203580 treatment suppressed trypsin-induced upregulation of protein expression of inducible nitric oxide synthase (iNOS),and subsequently reduced nitric oxide (NO) levels.Conclusions The regulation of p38 MAPK was involved in the trypsin-induced injury in esophageal epithelial cells.
