Objective To evaluate the diagnostic value of surface enhanced laser desorption/ionization time of flight mass spectrom-etry(SELDI-TOF-MS) for Paget disease. Methods The relative contents of serum proteins of 15 healthy people,15 patients with chronic eczema and 20 patients with Paget were detected by Weak cation exchanger protein chip (WCx2) and SELDI-TOF-MS. Results The con-tents of two proteins (3868Da,8876Da) had significant difference in healthy people and Paget disease patients(P<0.01). 291IDa, 3868Da and 5097Da protein peaks had significant difference in chronic eczema and Paget disease(P<0.05). Conclusion It shows great potentiality for early diagnosis and screening the tumor biomarkers of Paget disease with SELDI-TOF-MS.

Objective:To investigate the efficacy and safety of sindilizumab combined with apatinib in the treatment of elderly patients with advanced recurrent and metastatic esophageal squamous cell carcinoma.Methods:A total of 74 elderly patients with recurrent and metastatic esophageal squamous cell carcinoma who were admitted to Xuancheng City Central Hospital from March 2019 to August 2020 were selected, and they were divided into study group and control group by random number table method, with 37 cases in each group. The control group was treated with apatinib mesylate, and the study group was treated with sindilizumab combined with apatinib mesylate. All patients were treated for 2 cycles and followed up for 1 year. The efficacy, peripheral blood tumor marker levels, adverse reactions and survival were compared between the two groups.Results:The objective response rate and clinical control rate in the study group were higher than those in the control group [35.1% (13/37) vs. 13.5% (5/37), 67.6% (25/37) vs. 43.2% (16/37)], and the differences were statistically significant ( χ2 = 4.70, P = 0.030; χ2 = 4.43, P = 0.035). After treatment, the levels of carcinoembryonic antigen (CEA), squamous cell carcinoma-associated antigen (SCC-Ag) and cytokeratin 19 fragment antigen 21-1 (CYFRA21-1) in the two groups were all lower than those before treatment (all P < 0.05); the levels of CEA, SCC-Ag and CYFRA21-1 in the study group were lower than those in the control group (all P < 0.05). There were no differences in the incidence rates of fatigue, proteinuria, bone marrow suppression, and hand-foot syndrome between the two groups (all P > 0.05). After 1 year of follow-up, 20 patients in the study group survived, and the 1-year overall survival (OS) rate was 54.1%; 10 patients in the control group survived, and the 1-year OS rate was 28.6%; the difference in OS between the two groups was statistically significant ( χ2 = 4.06, P = 0.044). Conclusions:Sintilimab combined with apatinib has a good efficacy in the treatment of elderly patients with advanced recurrent and metastatic esophageal squamous cell carcinoma. This regimen can reduce the levels of tumor markers, improve the short-term survival rate of patients, and has good safety.

Objective To explore the impact of glucocorticoid on coagulation through administrating on rats with smoke inhalation.Methods Totally 150 male S-D rats were randomly (random number) divided into 5 groups:control group (ambient air inhalation),smoke group (smoke inhalation for 30 min),smoke+high dosage methyl prednisolone group(MP 40 mg/kg,intraperitoneal injection,s+HMP group),smoke+medium dosage MP (4 mg/kg) group (s+MMP group),smoke+low dosage MP (0.4 mg/kg) group (s+LMP group) (all n=30).Survival rates were calculated 24 h after smoke inhalation.Lung tissues were collected for histopathology and wet to dry (W/D) ratio.Arterial blood was collected for blood gas test.Coagulation factors in lung and plasma were tested.Results Survival rates of three MP groups were markedly improved compared with the smoke group (all P＜0.05),and was significantly higher in the medium dosage group(85.17％) than those in the low and high dosage groups (65.73％ and 60.07％,all P＜0.05).The W/D ratio and blood gas test were markedly improved in the high and medium groups (all P＜0.05).Tissue factor (TF) and thrombin-antithrombin complex (TAT-c) in bronchoalveolar lavage fluid (BALF) increased dramatically after SI (P＜0.01,P=0.005) with a remarkable drop of factor Ⅱ (F Ⅱ) (P=0.007),all of which were attenuated by MP with dosage dependence.The mRNA expression of TF increased dramatically after SI and recovered significantly with MP administration,while the expression of thrombomodulin (TM) recovered in the opposite direction with MP,all of which were in a dosage dependent manner.TF,fibrinogen (FIB),TAT-c increased significantly in plasma after smoke inhalation (P＜0.01,P=0.027,P=0.005).F Ⅷ ％ increased with MP administration and TF was raised by high dosage MP compared with the smoke group.FIB and TAT-c were decreased in all MP groups,which were significant higher in the high and middle dosage groups.The change of TM and endothelial cell protein C receptor (EPCR) in circulation were similar with FIB or TAT-c with or without MP.Protein C (PC％) and antithrombin (AT Ⅲ ％) dropped dramatically after SI,high and middle dosages of MP could restore the activity significantly,while low dosage would restore AT Ⅲ ％ but not PC％.Conclusions Glucocorticoid can significantly improve local and systemical coagulation disorder caused by smoke inhalation,and high-and medium-dosage hormones are effective.The regulation of hormones on the coagulation system is an important mechanism in the treatment of smoke inhalation induced lung injury.

Objective To investigate the therapeutic effect of different doses of methylprednisolone (MP) in smoke inhalation-induced acute lung injury (SI-ALI).Methods Adult male Sprague-Dawley (SD) rats were divided into control group (group A,n = 6), smoke inhalation group (group B, smoke inhalation 30 minutes,n = 30) and smoke+MP 40, 4, 0.4 mg/kg intervention group (groups C, D, E; intraperitoneal injection of MP at 1 hour before smoke inhalation, n = 30) according to random number table method. The survival status of rats in each group was observed at 24 hours, and murine smoke inhalation induced trauma score (MSITS) according to the symptoms and signs of rats at 3 hours after smoke inhalation were scored. The blood of abdominal aorta of rats was collected. Then the rats were sacrificed to harvest bronchoalveolar lavage fluid (BALF) and lung tissue. The levels of interleukin (IL-6, IL-17a) in plasma and BALF were detected by enzyme linked immunosorbent assay (ELISA); the total number of white blood cells and the proportion of leukocytes or macrophages in BALF were calculated; the histopathological changes of lung were observed and the lung injury score was given; the expression of myeloperoxidase (MPO) and high mobility group protein B1 (HMGB1) in lung tissue were detected by Western Blot.Results The 24-hour survival rate of group B rats was 33.67％. The survivalrate of groups C, D and E (65.73％, 85.17％, 60.07％) were significantly higher than that of group B (allP < 0.05), and the survival rate of group D was significantly higher than that of groups C and E. Diffuse inflammatory cell infiltration, intra-alveolar hemorrhage and a large amount of edema fluid were seen in the lung tissue of group B; and the lung injury score was significantly higher than that of group A. Compared with group B, the lung injury in different doses of MP group were decreased to different degrees, while the lung injury scores in groups C and D were significantly decreased (3.31±1.37, 2.62±0.98 vs. 5.52±0.97, bothP < 0.01); correlation analysis showed that MSITS score was significantly and positively correlated with lung injury score (r = 0.862,P < 0.001). The levels of plasma inflammatory factors and BALF protein, inflammatory cells and inflammatory factors, and the expression of MPO, HMGB1 in group B were significantly higher than those in group A. Compared with group B, the levels of inflammatory factors in plasma, and protein content, inflammatory cells and inflammatory factors in BALF in different doses of MP group were decreased to different degrees, with significant differences in groups C and D [plasma: IL-17a (pg/L): 49.28±27.12, 36.57±16.52 vs. 191.79±88.21; IL-6 (ng/L): 206.47±109.96, 197.52±113.86 vs. 669.00±299.60; BALF: protein content (mg/L):892.0±164.5, 566.1±120.9 vs. 1838.0±145.8; white blood cell count (×109/L): 5.40±1.67, 2.81±1.20 vs. 9.02± 2.06; neutrophil ratio: 0.315±0.081, 0.273±0.080 vs. 0.590±0.096; IL-17a (ng/L): 22.63±8.62, 18.92±8.43 vs. 43.31±19.17; IL-6 (ng/L): 156.49±46.94, 123.66±64.91 vs. 253.43±80.03; allP< 0.01]; in addition, the expression of MPO and HMGB1 protein in lung tissues of MP groups with different doses were significantly decreased, the expression of MPO in group D was significantly lower than that in group E [MPO/β-actin (fold increase from group A):2.14±0.97 vs. 4.35±0.87,P < 0.01], the expression of HMGB1 in groups C and D were significantly lower than that in group E [HMGB1/β-actin (fold increase from group A): 1.77±0.73, 1.23±0.67 vs. 3.65±1.08, bothP < 0.05]. Conclusions MP can significantly improve the survival rate of SI-ALI rats and reduce the acute pulmonary and systemic inflammatory response. The MP effect of 4 mg/kg was better than 40 mg/kg and 0.4 mg/kg.
