Objective:To investigate the effects of thalidomide on vascular endothelial growth factor(VEGF) and quality of life in patients with primary hepatocellular carcinoma after transcatheter arterial chemoembotization.Methods:A total of 60 patients with HCC,who were treated with transcatheter arterial chemoembolization (TACE) in Affiliated Hospital of Chengde Medical University from January 2014 to January 2016,were randomly divided into group A (n=30)and group B (n=30).Group A was treated with Thalidomide in combination with TACE,oral 200 mg every night for 1 month;group B was treated with TACE alone.The levels of VEGF in the two groups were detected before treatment and 3 weeks after treatment;the quality of life of patients before treatment and 1 month after treatment was evaluated by quality of life scale (QOL);the weight of two groups before and after treatment and adverse reactions during treatment were compared.Results:There was no significant difference in VEGF levels between the two groups before treatment (P＞0.05).After treatment,the levels of VEGF in the two groups were higher than those before treatment,and the VEGF levels in the group A was significantly lower than that in the group B,the difference was statistically significant (P＜0.01).There was no significant difference in QOL score and body weight between the two groups before treatment (P＞0.05).The QOL scores of the two groups after treatment were lower than those before treatment,but the QOL scores of patients in group A were significantly higher than those in group B (P＜0.05).There was no significant difference in weight between the two groups before and after treatment (P＞0.05).In group A,1 patients (3.33％) had severe somnolence,2 (6.67％) patients stopped taking thalidomide due to severe dry mouth,and the remaining 27 patients were able to tolerate.Conclusion:Thalidomide combined with TACE in the treatment of patients with HCC can reduce the levels of VEGF and improve the quality of life of cancer patients,which is worthy to be popularized in clinic.

Protein phosphorylation is one of the most common post-translational modifications (PTMs)in various organisms,which plays critical roles in the regulation of intracellular biological processes,such as cell prolifera-tion,signal transduction,metabolismis and tumorigenesis.However,the low abundance of phosphoprotein in the biological systems poses significant challenges of current analytical techniques.In order to further understand the phosphoproteomics,the roles of phosphorylated proteins in life process,discovery of biomarkers,diagnosis and treatment of disease,enrichment strategies of high efficiency have been developed,including the design of new nanomaterials and combination of a variety of analytical methods,et al.In this paper,we reviewed the develop-ment of enrichment strategies for phosphoproteomics and application of phosphoproteomics in disease.

Objective To discuss the relationship of drip velocity of nitrate on blood pressure while treating coronary disease,in order to provide appropriate drip velocity for clinical treatment.Methods 155 patients with coronary disease using nitrate to lower blood pressure were selected.They were divided into the nitro glycerin group(85 cases) and the isosorbide mononitrate group( 70 cases) according to difference of medication.The velocity of drugs was adjusted on basis of blood pressure changes.The blood pressure changes at different drip velocities were observed and compared.Results The systolic pressure and the diastolic pressure between two groups showed no difference at 20 drops/min,but the results were the opposite at 30 drops/min.The systolic pressure and the diastolic pressure in the nitro glycerin group showed evident changes at different drip velocities,but in the isosorbide mononitrate group,these changes were not so significant.9 patients in the nitro glycerin group had headache during treatment,no headache occurred in the isosorbide mononitrate group.Conclusions Intravenous use of nitrate at a velocity of 20 drops/min is relative secure.The risk of hypotension will increase if the medication speed increases.lsosorbide mononitrate has little influence on blood pressure.

Objective:To establish a method for the determination of omeprazole delayed release capsules and investigate the be-havior of reference preparations to provide experimental basis for generic drugs quality consistency evaluation. Methods:According to the first dissolution method (basket method) stated in 0. 931 of Chinese Pharmacopeia (2015 edition), the type of release media, solu-bility and stability of omeprazole in different media, effect of different treatment methods on the drug adsorption in the solution, differ-ent rotation speed and the methodology of ultraviolet spectrophotometry were investigated. Results:The rotation speed was 75 r·min-1 with the dissolution medium volume of 900 ml. The dissolution profiles of omeprazole delayed release capsules in three different media ( pH 6. 0 phosphate buffer, pH 6. 8 phosphate buffer and water containing 3% Tween-80) were determined with online filteration. The solubility of omeprazole in the different media was 0. 123, 0. 078 and 0. 275 mg·ml-1 , respectively. The results showed that ome-prazole was degraded 44%, 8% and 14% in 2 h in the above three release media, and degraded up to 43% in 6 h in water containing 3% Tween-80. The linear of omeprazole was 0. 209 4-20. 94, 0. 204 8-20. 48 and 0. 2016-20. 16 μg·ml-1 with the average recovery of 99.3% (RSD=0.7%,n=12), 99.7% (RSD=0.9%,n=12) and 99.5% (RSD=0.6%,n=12) respectively in the three media. Conclusion:The method is accurate and reliable, which can be used to study the quality consistency of omeprazole delayed re-lease capsules.

Objective: To describe the clinical characteristics with long-term prognosis in patients with mid-ventricular obstructive hypertrophic cardiomyopathy (MVOHCM).
Methods: A total of 66 MVOHCM patients treated in our hospital were retrospectively studied for their morbidity, clinical characteristics and mortality. The cumulative survival rate was calculated by Kaplan-Meier method; the risk factors for cardiac death and cardiovascular events were analyzed by uni- and multivariate Cox proportional hazard model.
Results: There were 66 (2.74%) patients suffering from MVOHCM among 2413 patients of hypertrophic cardiomyopathy and the average diagnostic age was (40.16 ± 14.64) years. With (7.30 ± 6.25) years of follow-up study, the cardiovascular mortality was 13.6% and unexplained syncope (HR=13.37, 95% CI: 1.65-114.46, P=0.015) was the independent predictor for cardiovascular death. There were 45.45% (30/66) patients experienced at least 1 time of cardiovascular event and the most frequent one was non-sustained ventricular tachycardia (NSVT); 19.70% (13/66) of patients combined with apical aneurysms, and they were more inclined to experience NSVT.
Conclusion: MVOHCM patients usually have unfavorable prognosis with the higher incidence of cardiovascular events, some patients may develop apical aneurysm. The early diagnosis of MVOHCM is important for appropriate treatment.

Objective:To investigate the clinical characteristics and prognosis of neonatal chylothorax.Methods:The clinical data of newborns diagnosed with chylothorax from June 2016 to June 2023 in Neonatal Center of Beijing Children's Hospital were retrospectively analyzed, and divided into congenital group and acquired group according to the pathogenesis of chylothorax. The clinical characteristics, treatment methods and prognosis of the two groups were compared.Results:A total of 23 cases were included, including 17 cases (73.9%) in the congenital group and 6 cases (26.1%) in the acquired group. There was no significant difference in gender, gestational age and birth weight between the two groups ( P>0.05). Compared with the acquired group, the proportion of lymphocytes (97.0% vs. 85.0%), the use of erythromycin (7/17 vs. 1/6) and octreotide (9/17 vs. 1/6) and special formula milk feeding (13/17 vs. 2/6) were higher in the congenital group; the proportion of right hydrothorax (1/17 vs. 3/6), invasive mechanical ventilation (6/17 vs. 6/6) and breastfeeding (0/17 vs. 3/6) were lower in the congenital group ( P<0.05). There were no significant differences in terms of the white blood cell count in pleural fluid and plasma protein content, incidence of bilateral and left pleural fluid, proportion of closed thoracic drainage, maximum daily drainage volume, drainage duration, total drainage volume, albumin utilization rate, length of stay and survival rate between the two groups ( P>0.05). 18 cases of pleural effusion absorption without recurrence after conservative treatment; 5 cases died, of which 4 cases died after their parents abandoned treatment, and 1 case died of neonatal necrotizing enterocolitis after thoracic duct ligation surgery. Conclusions:Congenital chylothorax and acquired chylothorax were similar in severity, course of disease and overall prognosis. The utilization rate of erythromycin and octreotide in congenital chylothorax was higher than that in acquired chylothorax. The neonatal chylothorax is usually with an overall good prognosis.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
