Objective To explore the correlation of epicardial adipose tissue (EAT) volume with atrial fibrillation (AF) and its recurrence after radiofrequency ablation (RA).Methods Eighty-five AF patients (AF group) and 90 non-AF patients (control group) were chosen between January 2014 and May 2016.Their EAT volumes were measured by CT scanning.Patients in AF group after RA were followed up 6-18 months,and the recurrence of AF was recorded.The recurrence of AF within 3 months of RA was defined as blanking recurrence group (n =27) and non-blanking recurrence group (n =58),and that after 3 months of RA was defined as the 1 ong-term recurrence.Results The total EAT volume and left atrial EAT volume were significantly larger in blanking recurrence group than in non-blanking recurrence group [(118.71 ±28.94) cn3 vs (97.73 ±24.86)cm3,(29.98 ±8.09)cm3 vs (23.11 ±8.30)cm3,t =6.219,4.451,P ＜ 0.01].Multivariate logistic resgression analysis showed that total EAT volume and left atrial EAT volume were the independent risk factors for AF.All showed that total EAT volume and left atrial EAT volume were the independent risk factors for blanking recurrence.The incidence of long-term recurrence was significantly higher in blanking recurrence group [40.7％ (11/27)] than in non-blanking recurrence group [15.5 ％ (9/58)] (x2 =7.142,P ＜ 0.05).Conclusions The incidence of AF is higher in patients with a Iarger total EAT volume and a larger left atrial EAT volume and AF is easier to recur even though after RA.

Objective To study the relation of epicardial adipose tissue (EAT) thickness with 1eftventricular remodeling and dysfunction in dilated cardiomyopathy (DCM) patients.Methods One hundred and twenty DCM patients who received treatment from Febuary 2012 to February 2016 were served as DCM group,and 76 healthy subjects undergoing physical examination were served as control group.Their left ventricular end-diastolic diameter (LVEDD),left ventricular end systolic diameter (LVESD),left ventricular end diastolic volume (LVESV),left ventricular end systolic volume (LVEDV),left ventricular end diastolic volume index (LVEDVI),left ventricular end systolic volume index (LVESVI),sphericity index (SI),leftventricular ejection fraction (LVEF),and EAT thickness were measured by routine cardiac ultrasonography and compared between two groups.Results The levels of LVESD,LVEDD,LVESV,LVEDV,LVESVI,LVEDVI and EAT thickness in DCM group were significantly higher,and the levels of LVEF,SIS and SID in DCM group were significantly lower (P＜0.05).The EAT thickness in DCM group with NYHA class Ⅱ,Ⅲ,Ⅳ was (8.1 ± 1.8),(7.8 ± 2.0),(7.9 ± 1.7) mm,and there was significant difference (F=1.973,P＞ 0.05) Linear correlation analysis showed that the EAT thickness was positively related with the LVESD,LVEDD,LVESV,LVEDV,LVEDVI,LVESVI,SISand SID (r =0.247,0.231,0.256,0.267,0.293,0.281,0.261,0.237,P＜0.05).There was no relationship between EAT thickness and LVEF (r =0.132,P＞ 0.05).Logistic multifactor regression analysis showed that EAT thickness was an independent risk factor for left ventricular remodeling in DCM patients (OR =0.793,95％CI:0.431-1.734,P =0.039).Conclusions The EAT thickness is significantly related with the left ventricular remodeling and can be used as an independent risk factor for predicting left ventricular remodeling in DCM patients.

Objective To study the effect of Tacrolimus on blood lipid after renal transplantation,and the relationship between C825T polymorphism in G protein beta 3 subunit (GNB3) gene and serum lipid levels.Method Eighty-one cases of recipients patients after renal transplantation were divided into two groups in terms of Tacrolimus concentration:normal blood concentration group (group A) and low blood concentration group (group B).The serum lipid levels at 1st,3rd,6th,and 12th month after renal transplantation were measured.Genotype was determined by the simple sequence-specific primer polymerase chain reaction (SSP-PCR).Result The percentage of patients with hypertriglyceride in group A was significantly higher than in group B during the one-year follow-up period.There was significant difference between the two groups in the serum triglyceride levels but no difference in the serum cholesterol levels.The 825C/T polymorphism in the GNB3 gene was not associated with hypertriglyceride in renal transplantations in Wenzhou.Conclusion The serum triglyceride levels in renal transplantations in Wenzhou was associated with the Tacrolimus concentration,and the incidence of hypertriglyceride is not associated with the 825C/T polymorphism in the GNB3 gene.

ObjectiveTo investigate the population with an advantage of clinical cure previously treated with nucleos(t)ide analogues (NAs), and to provide more methods for clinicians in pursuing the clinical cure of hepatitis B. MethodsA total of 42 chronic hepatitis B patients with low-level HBsAg who received NAs treatment in Hebi Third People’s Hospital from October 2017 to October 2019 were enrolled as subjects and divided into combination treatment group (group A) and NA monotherapy group (group B). The 22 subjects in group A were treated with NAs combined with PEG-IFN antiviral therapy for 48 weeks, and some patients withdrew from PEG-IFN after 24 weeks and continued to receive NA monotherapy, while the 20 subjects in group B received NA antiviral therapy alone. Both groups were observed till week 48, and the five makers for hepatitis B were measured to evaluate clinical outcome. The t-test was used for comparison of continuous data between two groups, and the Fisher’s exact test was used for comparison of categorical data between two groups; a multivariate logistic regression analysis was used to perform a multivariate analysis. ResultsCompared with group B at the 48-week treatment endpoint, group A had significantly higher HBsAg clearance rate (45.5% vs 0, P＜0.01) and HBsAg seroconversion rate (31.8% vs 0, P＜0.01). The population with HBsAg ＜1000 IU/ml, ＜500 IU/ml, ＜100 IU/ml, and ＜10 IU/ml had an HBsAg clearance rate of 52.6%, 61.5%, 66.7%, and 100%, respectively, and the population with an HBsAg level of 500-1000 IU/ml, 100-500 IU/ml, 10-100 IU/ml, and ＜10 IU/ml had an HBsAg clearance rate of 33.3%, 50%, 40%, and 100%, respectively. The 4 patients with baseline HBsAg ＜10 IU/ml (accounting for 18.2% in group A) achieved clinical cure at week 12 of combined treatment, and after observation to week 48, 2 patients had an anti-HBs level of ＞100 IU/ml and 2 had an anti-HBs level of ＞1000 IU/ml. The multivariate logistic regression analysis of HBsAg clearance showed that age at the initiation of combined treatment affected HBsAg clearance (odds ratio ［OR］=0.877, 95% confidence interval ［CI］: 0.781-0.985, P=0.026), and most of the patients with HBsAg clearance had an age of 36-49 (44.20±4.49) years; baseline HBsAg level also had an impact on HBsAg clearance (OR=0.996, 95% CI: 0.992-1.000, P=0.050). ConclusionThe addition of interferon therapy in chronic hepatitis B patients with low-level HBsAg previously treated with NAs can significantly improve the clinical cure rate. The younger the age and the lower the HBsAg level, the shorter the duration of combined treatment. Age and baseline HBsAg level are more important than the duration and type of NA medication.

【Objective】 To evaluate the quality of platelet concentrates (PCs) prepared by traditional and modified buffy coat centrifugal canning methods, and to explore the effect of modified buffy coat centrifugal canning method on improving the quality of PCs. 【Methods】 The buffy coat centrifugal canning methods was divided into traditional group and modified group. In the traditional group, the buffy coat component bag and empty bag were directly combined layer by layer and vertically canned for light centrifugation. In the modified group, a foam spacer was added between the buffy coat component bag and the empty bag for light centrifugation layer by layer. The effects of the two groups of centrifugal canning methods on the preparation quality of PCs were observed. 【Results】 The platelet content in PCs prepared by the modified buffy coat centrifugal canning method was significantly higher than that in the traditional group, and the mixed amount of red blood cells was lower than that in the traditional group (P<0.05). Although there was no statistically significant difference in the qualified rate of platelet content between the two groups (P>0.05), the qualified rates of platelet content and mixed red blood cell in the modified group were higher than those in the traditional group (P<0.05). 【Conclusion】 The modified centrifugal canning method with buffy coat can improve the quality of PCs, which is convenient and cheap, and is worth popularizing.

Objective To explore the clinical efficacy of high-frequency electric snare device under elec-tronic laryngoscope in the treatment of epiglottic cyst.Methods A total of 100 patients with definitely diag-nosed epiglottic cyst receiving outpatient operation treatment in the First Affiliated Hospital of Gannan Medi-cal University from April 2021 to March 2023 were selected as the research subjects and included into the ob-servation group and control group according to the visiting order,50 cases in each group.The observation group was treated with high-frequency electric snare for epiglottic cyst resection under electronic laryngo-scope,and the control group was treated with laryngeal tissue forceps under electronic laryngoscope for uncov-ering operation of epiglottic cyst.The operation time,intraoperative blood loss volume,pain degree within postoperative 24 h,pain duration,complete resection rate and recurrence rate in postoperative 3 months were compared between the two operation methods.Results The operation time,intraoperative blood loss volume,VAS score within postoperative 24 h and pain duration in the observation group were significantly less than those in the control group,the complete resection rate was significantly higher than that in the control group,and the differences were statistically significant (P<0.05).The two groups were followed up for 3 months. Only 2 cases in the control group relapsed,which were epiglottic multiple cyst,and the recurrence rate had no statistical difference between the two groups (P>0.05).No dyspnea,massive bleeding and epiglottic adhesion appeared.Conclusion The high-frequency electric snare device under electronic laryngoscope for treating epi-glottic cyst has the advantages of short operation time,less blood loss,postoperative light pain and high com-plete resection rate.

Objective: To evaluate the suitability of the existing hemolysis rate standards for locally processed red blood cell components by retrospectively analyzing 5-year hemolysis rate data at the end of storage. Methods: A total of 720 blood samples of three types of red blood cell components from our blood station from January 2019 to December 2023 were collected. Parameters included hemoglobin concentration (Hb), hematocrit (Hct), and free hemoglobin concentration (fHb). Hemolysis rate were taken as the control standard of 0.8% in accordance with the national standard. The hemolysis rates were compared against the national standard threshold of 0.8% (GB18469-2012), and annual trends of the detection parameters were observed. Results: The hemolysis rates (x-+s,%) of leukocyte-depleted whole blood at the end of storage were (0.038±0.023 8) in 2019, (0.049±0.039 5) in 2020, (0.043±0.040 7) in 2021, (0.049±0.030 7) in 2022, and (0.058±0.054 8) in 2023, respectively; The hemolysis rates (x-+s" />,%) of leukocyte-depleted suspended red blood cells at the end of storage were (0.093±0.050 2) in 2019, (0.086±0.049 5) in 2020, (0.123±0.072 3) in 2021, (0.122±0.052 1) in 2022, and (0.106±0.058 6) in 2023, respectively; The hemolysis rates (x-+s,%) of washed red blood cells at the end of storage were (0.127±0.038 2) in 2019, (0.150±0.066 5) in 2020, (0.121±0.052 2) in 2021, (0.124±0.038 9) in 2022, and (0.128±0.044 3) in 2023, respectively. Conclusion: Hemolysis rates at the end of blood storage of three red blood cell components were significantly lower than the limits specified in Quality Requirements for Whole Blood and Components (GB18469-2012), as well as standards from the EU, AABB and the United States. The results demonstrate excellent product quality control. A regional internal control standard of <0.2% is proposed for hemolysis rates at the end of storage.

BACKGROUND: We aim to explore the association between self-reported snoring and hypertension among adults aged 30-79 in Chongqing, China. METHODS: A total of 23,342 individuals aged 30-79 were included at baseline from August 2018 to January 2019, and the final sample size for the analysis was 22,423. Face-to-face interviews and physical examinations were conducted by trained investigators. Logistic regression was performed to study age-specific and gender-specific associations between snoring and hypertension. RESULTS: Frequent snoring was associated with the risk of hypertension for each age and gender group, and the frequency of snoring was positively correlated with the risk for hypertension. For the three age groups (< 45, 45-59, ≥ 60), compared with the non-snoring group, those who snore often had a 64.5%, 53.3%, and 24.5% increased risk of hypertension (< 45: OR = 1.65, 95%CI 1.34-2.02; 45-59: OR = 1.53, 95%CI 1.37-1.72; ≥ 60: OR = 1.25, 95%CI 1.09-1.42), respectively. For men and women, those who snore often had a 46.8% and 97.2% increased risk of hypertension, respectively, than the non-snoring group (men: OR = 1.47, 95%CI 1.33-1.63; women: OR = 1.97, 95%CI 1.75-2.23). CONCLUSIONS People who snore frequently should pay close attention to their blood pressure levels in order to achieve early prevention of hypertension, particularly for snorers who are female and aged under 45; importance should be attached to their blood pressure control.
