OBJECTIVE:To observe the therapeutic efficacy of reduced glutathioue plus Xiangdan injection for anti-tuberculosis drug-induced hepatic lesion. METHODS:A total of 75 patients with anti-tuberculosis drug-induced hepatic lesion were randomly divided into two groups:38 cases (trial group) were assigned to receive reduced glutathioue (1.2 g) that was added into normal saline(250 mL) by iv gtt q.d plus Xiangdan injection (20 mL) that was added into 10% glucose injection (250 mL) q.d by iv gtt;37 cases(control group)received potassium magnesium injection (20 mL)which was added into 10% glucose injection(250 mL) q.d by iv gtt. After treatment for 4 weeks,the liver function parameters and the total effective rates in two groups were measured. RESULTS:Compared with control group,the liver function had a significantly better improvement in trial group (P

Objective Identify the mechanism of induced atrial arrhythmias after pulmonary vein isolation (PVI) in patients with paroxysmal atrial ifbrillation(PAF), and investigate its long-term prognosis. Methods All patients with PAF undergoing PVI and induction test afterwards between Feburary 2010 and October 2010 were included. The induction protocol was rapid pacing initiated at cycle length of 250 ms with progressive shortening in a decrement of 10 ms down to 180 ms or refractoriness. Isoproterenol of 2-4μg/min was administrated as well. Inducibility was deifned as induction of atrial arrhythmia lasting >1 min. The mechanism of induced tachycardia was identiifed by activation mapping and entrainment mapping under the guidance of CARTO system. All patients were followed up by 36 months. Results Forty-nine atrial tachycardia were induced in 39 (19.7%) patients, including 35 organized atrial tachycardia (OAT) and 14 atrial ifbrillation (AF). The LA diameter was signiifcantly larger in inducible group than non-inducible group (39.5±6.6 mm vs. 36.7±5.2 mm, P=0.004). Macroreentry was the most common mechanism in induced OATs (28, 80.0%), and mitral isthmus was the most common critical site (20, 40.8%), followed by cavo-tricuspid isthmus (12, 24.5%), PV (6, 12.2%), LA septum (4, 8.2%), superior vena cava (3, 6.1%) and LA roof (1, 2.0%). Conclusions The most common mechanism of induced tachycardia by IV isoproterenol and rapid pacing is MI and CTI dependent after PVI in PAF patients, which can be succssefully eliminated by liner ablation, not increasing long-term recurrence rate.

The micro-elimination strategy is an effective approach to rapidly reduce the incidence and mortality of specific populations infected with hepatitis C virus (HCV). This article combines the current status of hepatitis C prevention and treatment in Guizhou Province, and introduces the current domestic and foreign hepatitis C micro-elimination models. It is worth mentioning that the Guizhou Provincial Medical Quality Control Center for Infectious Diseases jointly formulated the "Guizhou Province Chronic Hepatitis C Health Education Standards" to improve the awareness of health care workers and patients about the disease, increase the screening rate, and increase the patients willingness to receive treatment and accomplish the World Health Organization’s goal of eliminating hepatitis C threat by 2030.

OBJECTIVETo determine the risk factor of HCC in Guizhou.

METHODSA group case-control study design was conducted between 762 cases and 798 controls in Guizhou province. The main related-factors were analyzed with unconditional logistic regression model and evaluated by odds ratio (OR) and 95% confidence interval (95% CI).

RESULTSThere are significant differences between cases and controls in regarding to cigarette smoking 210 (27.6%),non-alcoholic fatty liver disease 336 (44.1%), alcoholic liver disease 245 (32.2%), family history of HCC 141 (16.5%), alcohol consumption 300 (39.4%), HBV infection 436 (57.2%), pickled food 290 (38.1%), and economic status 5 years ago 420 (55.1%) in cases,and cigarette smoking 116 (14.5%),non-alcoholic fatty liver disease 160 (20.1%), alcoholic liver disease 101 (12.7%), family history of HCC 40 (5.0%), alcohol consumption 180 (22.6%), HBV infection 82 (10.3%), pickled food 225 (28.2%), and economic status 5 years ago 647 (81.1%) in controls, with OR of each variable was 3.520, 2.464, 4.330, 2.219, 2.451, 19.245, 6.212, 0.174 respectively, P less than 0.01.

CONCLUSIONHBV infection and pickled food were the most common risks for HCC in Guizhou. Alcohol consumption excessively and cigarette smoking may increase the risk too.

Objective: To investigate the effect of non-vitamin K antagonist oral anticoagulants (NOAC) on left atrial or atrial appendage (LA/LAA) thrombi in patients with nonvalvular atrial fibrillation (NVAF). Method: Data from 3 042 patients with atrial fibrillation(AF), who underwent transesophageal echocardiography (TEE) examination before cardioversion or catheter ablation for the detection of LA/LAA thrombus in our department from March 2016 to January 2018 were prospectively analyzed. Among these patients, LA/LAA thrombus was detected by TEE in 57 patients. A total of 19 patients who received dabigatran or rivaroxaban for ≥3 weeks and underwent repeated TEE were included, 38 patients were excluded (7 patients with rheumatic heart disease, 1 patient treated with pericardial decortication, 1 patient treated with surgical repair of endocardial cushion defect, 1 patient with LA thrombus associated with the atrial septal occluder device, 14 patients received warfarin therapy, 14 patients did not receive repeated TEE). Results: First repeated TEE results showed that LA/LAA thrombus was not completely resolved in 4 out of 4 patients treated with dabigatran (110 mg bid) for a median time of 119 (47, 258) days, whereas LA/LAA thrombus was completely resolved in 5 out of 11 patients treated with dabigatran (150 mg bid) for a median time of 80 (58, 147) days. Thrombus was completely resolved in 2 out of 2 patients treated with rivaroxaban (15 mg qd) for 110 days and 95 days respectively, and in 1 out of 2 patients treated with rivaroxaban (20 mg qd) for 91 days. Second repeated TEE was performed in 8 patients. Thrombus was resolved completely in 2 out of 3 patients with undissolved thrombus treated by dabigatran (110 mg bid) after increasing the dabigatran dosage (150 mg bid). Thrombus was resolved in 3 (1 patient prolonged treatment with dabigatran 150 mg bid and 2 patients switched to rivaroxaban 20 mg qd) out of 4 patients with undissolved thrombus under the dabigatran 150 mg bid regimen, whereas the thrombus remained unresolved in 1 patient switched to rivaroxaban (15 mg qd). After receiving rivaroxaban 15 mg bid treatment, the thrombus was finally resolved in 1 patient with undissolved thrombus treated by rivaroxaban 20 mg qd. There was no clinical thromboembolism or major bleeding events during the median follow up time of 462 (305, 558) days. Conclusions Our data show that NOAC is an effective therapeutic option for the treatment of LA/LAA thrombi. When eligible, a higher NOAC dosage may be preferred due to the higher efficacy on thrombus resolvement.

Objective: To investigate the incidence and clinical characteristics of left atrial appendage (LAA) thrombus in patients with hypertrophic cardiomyopathy (HCM) and non-valvular atrial fibrillation (AF) . Methods: Data from 10 440 patients with AF who had undergone transesophageal echocardiography (TEE) before cardioversion or catheter ablation at Beijing Anzhen Hospital from April 2006 to December 2018 were retrospectively screened. Two hundred and five HCM patients were included, 820 AF patients with the same CHA₂DS₂-VASc score over the same period were selected as the control group. HCM patients were divided into two subgroups based on presence or absence of LAA thrombus/sludge. The baseline of clinical information, transthoracic echocardiographic and TEE measures were compared among all the groups. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of left atrial diameter (LAD) for LAA thrombus/sludge. Multivariate logistic regression analysis was applied to analyze the correlative factors of LAA thrombus/sludge in HCM patients. Results: The incidences of LAA thrombus or sludge were higher in HCM group than in control group (10.7% (22/205) vs. 0.7% (6/820); 8.8% (18/205) vs.7.0% (57/820), P<0.001) . In HCM patients, LAD was significantly larger in LAA thrombus/sludge subjects than in those without thrombus/sludge ((48.9±5.1)mm vs. (45.2±6.1) mm, P<0.001). CHA₂DS₂-VASc score was similar between the two subgroups ((2.0±1.4) vs. (1.8±1.4), P>0.05). There was no difference in the rate of patients with a CHA₂DS₂-VASc scores ≥2 between the subgroups(62.5% (25/40) vs. 57.0% (94/165), P=0.525). The incidences of LAA thrombus in HCM and AF patients with CHA₂DS₂-VASc scores of 0, 1 and 2 were 8.8% (3/34) , 9.6% (5/52) , 11.8% (11/119) , respectively; and the rate of LAA sludge were 8.8% (3/52) , 7.7% (4/52) , 9.2% (11/119) , respectively. The cut off value of LAD for the diagnosis of LAA thrombus/sludge was 44.5 mm. Multivariate logistic regression analysis showed that LAD≥44.5 mm (OR=5.134, 95%CI 1.862-14.156, P=0.002) , non-paroxysmal AF (OR=2.782, 95%CI 1.238-6.252, P=0.013) , previous thromboembolism or stroke (OR=1.820, 95%CI 0.774-4.227, P=0.017) were independent determinants of LAA thrombus/sludge. Conclusions The incidence of LAA thrombus/sludge is higher in patients with HCM and AF than in AF patients without HCM. The CHA₂DS₂-VASc score is similar between HCM and AF patients with LAA thrombus/sludge and those without thrombus/sludge. Patients with CHA₂DS₂-VASc score 0-1 are also likely to suffer LAA thrombus/sludge. Left atrial enlargement is associated with LAA thrombus/sludge.

Objective: To evaluate the anti-gingivitis efficacy of a novel stabilized stannous-containing sodium fluoride dentifrice. Methods: A randomized, controlled and double blind clinical study was conducted. 156 adults with gingivitis were enrolled and randomly assigned to experimental group(group of novel stabilized stannous-containing sodium fluoride dentifrice, n = 51), positive control group (group of Yunnan Baiyao dentifrice, n = 54) and negative control group (group of Crest dentifrice, n = 51). Gingival health was assessed using Mazza Modification of the Papillary Bleeding Index(Mazza GI) at Baseline, day 3 and week 4 and pocket depth was evaluated at baseline and week 4, respectively. Results: At day 3 and week 4, the experimental and positive control groups exhibited lower clinical parameters than the negative control group(P＜ 0. 000 1). At week 4, the mean Mazza GI scores and PD of the experimental group were significantly lower than those of the positive control group(P＜ 0. 05). Conclusion: The novel stannous-containing sodium fluoride dentifrice has anti-gingivitis efficacy.

Preventing and mitigating major risk exposure is an important task for modern countries to maintain sustained and healthy economic development and overall social stability. In this manuscript, the authors introduced Israel′s current medical and health care risk prevention system, including the regional health emergency response coordination mechanism, hospital′s external emergency rescue capacity building and hospital′s internal security system. Israel′s risk prevention system has been tested by wars and terrorist attacks, as well as many infectious diseases outbreaks. Thus the authors expected that its successful experiences can be introduced as a reference for improving China′s medical and health care risk prevention system.
