Chronic hepatitis B (CHB) is still a global public health problem, resulting in the high risk of decompensated cirrhosis and hepatocellular carcinoma.At present, there are no single available medications that can induce both potent HBV DNA suppression, and high rates of HBeAg and HBsAg clearance.Therefore, there is great interest in developing combination therapies for patients with chronic HBV infection, which can achieve sustained viral suppression and HBsAg negative inversion after a finite course of treatment leading to clinical cure.This article reviews the current status and advances of combination therapy for CHB.

The electroencephalography (EEG) has a wide range of content, complex graphics and abstract theory. Meanwhile, there are differences in professional level, learning ability and subjective initia-tive among refresher doctors. In order to improve the quality of teaching, and to better serve the refresher doctors, the following strategies have been applied in the teaching process. We not only make the training target according to the actual condition of every refresher doctors, but also make them take a correct atti-tude towards study and follow the teaching arrangement. Besides, we not only orient at the operational skills training, including electrode installation, EEG evoked test, Point-of-Care test to eliminate the interference, but also promote the refresher doctors to seek the law of the diagram in the actual interpretation process with longitudinal development view and horizontal comparison perspective. Furthermore, we not only stan-dardize their report, but also broaden their view.

OBJECTIVETo study the effect and safety of haemostatic apozem combined with haemostatic mixture on hemophilia hemorrhage.

METHODSFive hundred hemophilia patients were randomly recruited from Shaanxi Yida Hematology Institute from February 2005 to July 2010. Under the condition of using no blood products such as platelet cofactors VIII and IX, oral administration of haemostatic apozem combined with intravenous dripping of haemostatic mixture were given to 332 hemorrhagic patients and 451 patients in need of surgery for hemorrhagic prevention. The treatment was lasted for three successive weeks. The hemostatic time, hemorrhage absorption (recovery) time, and their safety were observed.

RESULTSThe hemostatic time for open bleeding and closed bleeding was (0.85 +/- 0.83) h and (2.69 +/- 0.65) h respectively. The average hemostatic time was (2.00 +/- 0.69) h. The recovery time for different portions was as follows respectively: intra-cranial hemorrhage (14.13 +/- 6.01) days; muscular hemorrhage (18.18 +/- 7.34) days; hematuria (8.25 +/- 4.69) days; arthrorrhagia(3.27 +/- 1.31) days; ecchymoma (7.16 +/- 2.32) days; bleeding of oral and nasal cavities (4.26 +/- 1.35) days; intramedullary hemorrhage (19.15 +/- 1.36) days; hematoma ulceration (50.01 +/- 20.91) days. The hemorrhage recovery ratio was 99.10% (329/332). The success rate of preventing from surgery hemorrhage was 100% (451/451). No severe adverse reaction occurred during the therapeutic course.

CONCLUSIONSHaemostatic apozem combined with haemostatic mixture was effective and fast in preventing and treating hemophilia hemorrhage, with no complications or adverse reactions. It could be taken as the first choice for prevention and treatment of hemophilia hemorrhage.

Objective To analyze the therapeutic effect of intracoronary versus intravenous bolus tirofiban on myocardial perfusion and major cardiovascular events (MACE) in elderly patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and explore the optimal route of tirofiban application. Methods From July 2009 to July 2010, 120 NSTE-ACS patients undergoing percutaneous coronary intervention (PCI ) were consecutively enrolled in this study. They were randomly divided into two groups: intracoronary (60 cases) versus intravenous (60 cases) bolus tirofiban. Thrombolysis in myocardial infarction (TIMI) flow, TIMI myocardial perfusion grade (TMPG) and MACE 30 days after PCI were observed. Results The incidence of TIMI flow and TMPG 3 grade in intracoronary group were higher than in intravenous group [53(88.3%) vs. 38(63.3%); 53(88.3%) vs. 40(66.7%), respectively, both P＜0.05]. However, MACE incidence and bleeding complications during hospital 30 days after PCI had no significant difference between the two groups [1 (1.7%) vs. 0; 3(5.0%) vs. 5(8.3%)], which were not statistically significant (P＞0.05). Conclusions Intracoronary bolus tirofiban before PCI more effectively increases coronary blood flow and myocardium blush than intravenous route in elderly NSTE-ACS patients.

Pre-clinicaland clinical researches have confirmed the prominent radiosensitizing effect of hyperthermia. In this article, the research progress on hyperthermia combined with radiation therapy was summarized based upon clinical evidence. The challenges and issues during the procedure of hyperthermia combined with radiation therapy were analyzed from the perspectives of treatment temperature, frequency and interval time of hyperthermia, interval time and time sequence between hyperthermia and radiation therapy, etc. Besides, the application progress and prospect of hyperthermia combined with radiation therapy were reviewed, aiming to provide clinical evidence for the combination of hyperthermia and radiation therapy.

Objective:To explore the clinical effectiveness of hemostatic bandage on wound safety and comfort after transradial coronary angiography and/or interventional therapy.Methods:This was a experimental study. A total of 400 consecutive patients who underwent transradial coronary angiography and/or interventional therapy in the Department of Cardiology, Peking University Third Hospital from July to October 2022 were enrolled and randomly divided into the hemostatic bandage group and the hemostatic balloon compressor group by the envelope method with 200 cases in each group. The hemostatic bandage group and the hemostatic balloon compressor group were treated with hemostatic bandage and hemostatic balloon compressor as transradial artery hemostatic device, respectively, to observe and compare postoperative hemostatic effect, hemostat use time, complication rate, postoperative pain, the degree of numbness in the finger on the operated side and wristband comfort between the two groups.Results:The hemostatic success rate was 98.5% (197/200) and 99.0% (198/200) in the hemostatic bandage and the hemostatic balloon compressor group, respectively, with no statistical difference ( χ2=0.20, P>0.05). The hemostat use time in the hemostatic bandage group and the hemostatic balloon compressor group was (6.23 ± 0.47) h and (17.01 ± 7.74) h, respectively, and the difference was statistically significant ( t=-19.66, P<0.01). The incidence of complications in the hemostatic bandage group and the hemostatic balloon compressor group was 13.5%(27/200) and 29.5%(59/200), respectively, and the difference was statistically significant ( χ2=8.01, P<0.05). Among the complications, swelling occurred in 21 individuals of the hemostatic bandage group and 54 individuals of the hemostatic balloon compressor group with statistically significant differences ( U=16 689.50, P<0.01). Besides, the hemostatic bandage group was significantly better than the hemostatic balloon compressor group with statistically significant differences in wound pain at immediate postoperative ( U=13 669.50, P<0.01), in finger numbness at immediate postoperative and 1-hour postoperative (immediate postoperative: U=17 838.00, P<0.05; 1-hour postoperative: U=13 342.50, P<0.01), in comfort at immediate postoperative, 4-hours, 8-hours and 12-hour postoperative(immediate postoperative: U=9 966.50, P<0.01; 4-hour postoperative: U=12 851, P<0.01; 8-hour postoperative: U=14 900, P<0.01; 12-hour postoperative: U=15 920, P<0.01). Conclusions:The hemostatic bandage shows better hemostatic effect, shorter compression time, lower complication rate, less wound pain, less numbness of the finger on the operation side, and higher comfort of the wrist band compared to hemostatic balloon compressor after transradial coronary angiography and/or interventional therapy, which is worthy of clinical promotion.

Trace amines(TAs)are metabolically related to catecholamine and associated with cancer and neuro-logical disorders.Comprehensive measurement of TAs is essential for understanding pathological pro-cesses and providing proper drug intervention.However,the trace amounts and chemical instability of TAs challenge quantification.Here,diisopropyl phosphite coupled with chip two-dimensional(2D)liquid chromatography tandem triple-quadrupole mass spectrometry(LC-QQQ/MS)was developed to simul-taneously determine TAs and associated metabolites.The results showed that the sensitivities of TAs increased up to 5520 times compared with those using nonderivatized LC-QQQ/MS.This sensitive method was utilized to investigate their alterations in hepatoma cells after treatment with sorafenib.The significantly altered TAs and associated metabolites suggested that phenylalanine and tyrosine metabolic pathways were related to sorafenib treatment in Hep3B cells.This sensitive method has great potential to elucidate the mechanism and diagnose diseases considering that an increasing number of physiological functions of TAs have been discovered in recent decades.

OBJECTIVETo evaluate the association between perioperative bleeding post percutaneous coronary intervention (PCI) and 1 year adverse cardiovascular events in elderly patients.

METHODSFrom June 2006 to August 2011, 1 105 elderly ( ≥ 75 years) patients undergoing PCI in Fuwai Hospital were prospectively included. Patients were divided into peri-procedure bleeding group (n = 153) and no bleeding group (n = 952). Cox proportional hazards model was performed to evaluate the independent effect of bleeding on the composite endpoint of death and myocardial infarction.

RESULTSBARC 2 grade bleeding occurred in 9.5% (105/1 105) patients. The rate of BARC ≥ 2 grade bleeding was 11.8% (130/1 105) , and the access site-related bleeding accounted for 62.7% (96/153) of all bleeding. The composite endpoint of 1 year death and myocardial infarction was higher in bleeding group (9.2% (14/153) vs. 4.2% (40/952), P = 0.008) . The 1 year cardiac death was higher in bleeding group (3.9% (6/153) vs. 0.8% (8/952), P = 0.007), but the rate of non-cardiac death was similar between bleeding group and no bleeding group (P = 0.360). Cox proportional hazards model analysis showed that HR of 1 year death and myocardial infarction in BARC ≥ 2 grade bleeding patients was 2.368 (95%CI:1.201-4.669, P = 0.013) compared with no bleeding patients.

CONCLUSIONPerioperative bleeding post PCI is an independent predictor of 1 year adverse outcomes in elderly patients( ≥ 75 years).

Malignant tumors can be classified into three categories， rapidly progressing tumors， slowly progressing tumors， and "indolent" tumors. Rapidly progressing tumors （such as liver cancer， pancreatic cancer， and cholangiocarcinoma） have acute onset， shorter time duration from onset to death， and poorer treatment effects， which warrants primary prevention. Slowly progressing tumors （such as lung cancer， colorectal cancer， breast cancer， and gastric cancer） have slow onset， clear precancerous lesions， longer time duration from onset to death， and better therapeutic effects， which is accordingly suitable for secondary prevention. “Indolent” tumors （such as prostate and thyroid cancer） do not affect the life expectancy and are suitable for tertiary prevention. Early screening of “indolent” tumors may lead to overtreatment. Furthermore， early screening of rapidly progressing tumors is difficult to identify early cancers， which results in low cost-effectiveness. In contrast， for slowly progressing tumors suitable for secondary prevention， early screening may have cost-effectiveness， though there might be over-diagnosis. It is crucial to adopt appropriate prevention and treatment strategies for diverse types of tumors. Currently， large-scale cohort studies and randomized controlled clinical trials with complete follow-up may accurately evaluate the effect of cancer prevention strategies. This review discusses the significance of screening in precision prevention of tumors based on the characteristics of tumor progression and patients’ prognosis.
