Purpose To analyze retrospectively the clinicopahological characteristics and immuophenotype in 120 cases of pulmonary selerosing hemangioma ( PSH) . Methods Data of 120 cases of PSH were collected and reviewed, including gross features and frozen diagnosis, histopathological features, morphology in HE and immunohistochemical characteristics of tumor cells. Results PSH pres-ents a well-circumscribed mass with a sense of expansion after cutting, which showed a solid, grey to tan-yellow surface with foci of haemorrhage. Two kinds of tumor cells and four typical patterns with mixed forms, are often shown under light microscope (92/120, 76. 67%). Focal accumulation of histocytes and scattered mast cells were noted in some cases (83/120, 69. 17%). Both surface cells and round cells were TTF-1 and EMA positive. Surface cells expressed SP-A, CK and NapsinA. Round cells expressed vimentin. Conclusion Gross features and typical“two cell types, four patterns” contribute to PSH diagnosis. Meanwhile, foal accumulation of foam histocytes and scattered mast cells show a clue to PSH diagnosis and differential diagnosis.

Objective To investigate the relationship between the fluorouracil pathway gene and effect of chemotherapy in advanced gastric cancer after surgery. Methods 52 postoperative patients with advanced gastric cancer using FOLFOX4 6-cycles combined chemotherapy were collected to set up the database. The expression of thymidine synthase (TS), dihydropyrimidine dehydrogenase (DPD) and orotate phosphoribosyltransferase(OPRT) in tumor tissue and adjacent non-tumor tissue of 52 patients with advanced gastric cancer were measured by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). The influence of fluorouracil pathway gene on chemotherapy was investigated. Results The TS-mRNA level in tumor tissue was significantly higher than non-tumor tissue (0.92±0.28 vs 0.71±0.30) (t = 3.730, P =0.001).OPRT-mRNA level in tumor tissue was positively correlated with the non-tumor tissue (r =0.45, P =0.001). No correlations were observed among other gene expressions. Patients whose high OPRT-mRNA gene expression in their tumors and non-tumor tissue showed an obviously better survival (t = 3.036, P =0.003;t = 2.713, P =0.009). Patients with low DPD-mRNA gene expression survived longer than those with high DPD-mRNA gene expression in tumor tissue with statistical significance(t = 2.708, P =0.009), whereas prolonged survival was observed in patients with high DPD-mRNA gene expression in non-tumor tissue (t = 2.616, P =0.012).Conclusion There is close relationships between chemotherapy in advanced gastric cancer and the expression of DPD-mRNA, OPRT-mRNA;while the expression of TS-mRNA have no relation with the survival time.

Objective To study the anti-inflammatory,antitussive,and analgesia effects of Jinhua qingre capsules.Methods The anti-inflammatory effect was assessed by the methods include xylene-induced mouse auricular swelling and histamine-induced pigment oozing from skin vessel in rats;The antitussive and analgesic effect were assessed by ammonia water induced cough model and acetic acid-induced twisting method.Results In anti-inflammation experiment,the high dose (12 g·kg-1) and moderate (6 g·kg-1) groups of Jinhua qingre capsules showed significant inhibitory effect on auricular swelling and significant difference compared with control group (P ＜ 0.01,P ＜ 0.05.);the high dose (10 g· kg-1) and moderate dose (5 g·kg-1) groups of Jinhua Qingre capsules play a marked inhibitory role in the increase in mouse peritoneal capillary permeability (P ＜ 0.01,P ＜ 0.05).In antitussive experiment,high dose (12 g· kg-1) and moderate dose (6 g· kg-1) groups had significant inhibitory effect on cough caused by ammonia water (P ＜ 0.01,P ＜ 0.05) compared with control group.In analgesic experiment,the high dose (12 g·kg-1),moderate dose (6 g·kg-1),and low dose (3 g·kg-1) groups effectively reduced the writhing frequency of mice (P ＜ 0.01,P ＜ 0.05).Conclusion Jinhua qingre capsules have potential effects on anti-inflammatory,antitussive,and analgesic.

Objective:To investigate the clinical efficacy of second-line therapy with dasatinib in the treatment of chronic myeloid leukemia.Methods:Sixty patients with chronic phase chronic myeloid leukemia who received treatment in Hongqi Hospital of Mudanjiang Medical University between January 2015 and January 2021 were included in this study. They were randomly divided into control and observation groups, with 30 patients in each group. The control group was treated with conventional chemotherapy, and the observation group was treated with conventional chemotherapy combined with oral dasatinib. All patients were treated for 6 months. Clinical efficacy, immune function indexes, quality of life score, and incidence of adverse reactions (abnormal liver function, rash, fatigue, peripheral edema, nausea and vomiting, alopecia) were compared between the two groups.Results:Objective response rate (ORR) in the observation group was significantly higher than that in the control group [83.33% (25/30) vs. 53.33% (16/30), χ2 = 6.23, P < 0.05). Before treatment, there were no significant difference in immune function indicators between the two groups ( t = 0.03, 0.20, 0.44, all P > 0.05). After treatment, CD 4/CD 8, CD 3+ and natural killer cells in the observation group were (1.03 ± 0.32), (43.77 ± 6.62)%, (31.12 ± 3.38)%, respectively, which were significantly higher than (0.74 ± 0.28), (35.79 ± 6.27)%, (28.22 ± 2.84)% in the control group ( t = 3.69, 4.78, 3.60, all P < 0.05). The scores of social functioning, material well-being life, mental health, somatic health in the observation group were (85.48 ± 6.25) points, (80.12 ± 6.34) points, (79.94 ± 6.48) points, and (77.92 ± 5.81) points, respectively, which were significantly higher than (72.79 ± 5.89) points, (63.47 ± 5.82) points, (68.87 ± 6.08) points, (63.14 ± 6.12) points in the control group ( t = 7.91, 10.59, 6.82, 9.59, all P < 0.05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group [16.67% (5/30) vs. 40.00% (12/30), χ2 = 4.02, P < 0.05). Conclusion:Second-line therapy with dasatinib for chronic phase chronic myeloid leukemia is effective and safe. It can effectively improve the efficacy and safety of chemotherapy and can also improve immunological function and quality of life.

To investigate the anti-pyretic and anti-endotoxin effect of Chinese herb medicine Jinhuaqingre capsules.Thirty healthy male New Zealand rabbits with lipopolysaccharide-induced fever were divided into 5 groups (6 rabbits in each): animals in model group were given normal saline by gavage, animals in positive control group were given aspirin (0.2 g/kg), and animals in Jinhuaqingre groups were given Jinhuaqingre capsules 6.0, 3.0 or 1.5 g/kg, respectively. The changes in body temperature of rabbits were observed. Fifty healthy Kunming mice were divided into 5 groups (10 mice in each): mice in model group were given normal saline by gavage, mice in positive control group were given aspirin (0.2 g/kg), and those in Jinhuaqingre groups were given Jinhuaqingre capsules 6.0, 3.0, 1.5 g/kg, respectively. Matrix coloration method was used to detect the degradation rate of endotoxin in mice.The body temperature in rabbits of high and medium dose Jinhuaqingre capsule groups declined significantly 60 min after drug administration, and the temperature of high-dose group returned to the baseline after 300 min; while the body temperature of low-dose group started to decline at 180 min after drug administration. The endotoxin degradation rates in mice of high, medium and low dose groups was (56.73±3.12)%, (47.23±1.77)% and (21.08±2.30)% at 30 min after drug administration; those were (82.76±1.00)%, (64.75±1.77)% and (38.21±1.57)% at 60 min after drug administration, respectively.Chinese herb medicine Jinhuanigre capsules have anti-pyretic and anti-endotoxin effects, which may provide a new option for the treatment of heat-toxin syndrome.

The postoperative complications in patients with gastric or colorectal cancer has been common but seriously affecting patients' recovery and even their life safety.According to the database of China Gastrointestinal Cancer Surgery Union,abdominal infectious complications are the main causes of secondary surgery and postoperative death,which deserve clinical attention.However,the incidence rate of postoperative abdominal infection varies widely from center to center.Due to the lack of nationwide data,it is unable to determine the incidence of abdominal infectious complications reasonably and formulate the corresponding strategies of evidence-based diagnosis and treatment.Therefore,this multi-center prospective cohort study,i.e.prediction of abdominal complication after gastroenterological surgery (PACAGE),aims to investigate the incidence,classification and outcomes of postoperative abdominal infection in patients with gastric or colorectal cancer,to implement the standardization of the complication registration,and to provide necessary data for improving surgical safety,preventing abdominal infection and decreasing the rate of postoperative complications in the future.

Postoperative complications of gastrointestinal surgery have become an important indicator for evaluating surgical safety in the process of the domestic and foreign clinical research and practice.The clinical economics evaluation of the complications provides an important reference in the clinical decision-making process,in addition to the mechanism investigation.It reveals that higher cost-effectiveness can be obtained through optimizing complication diagnosis and registration process from a national macroscopic level,while it also uncovers the targets of the yet-to-be improved clinical decision making process in the microscopic analysis.Through clinical economics evaluation,the necessity and feasibility of interventions targeting the complications can be better understood the clinical practice,which would eventually optimize clinical strategies and proper use of the limited health resources.
