Objective To explore the application effect of the Mini-CEX evaluation model based on the OBE concept in the clinical Practice teaching of neurology.Methods We Selected 100 students who will Practice in the Department of Neurology from 2022 to 2023 as the research objects,and divided them into the experimental group(n=50)and the control group(n=50).Under the guidance of the OBE concept,the experimental group was guided by learning outcomes,refined the teaching objectives,and applied the Mini-CEX evaluation mode for evaluation and feedback.In contrast,the control group adopted the traditional teaching mode.Combined with the observation data,we analyzed and compared the data of various indicators of the two groups of students at the beginning and end of the internship.Results At the end of the internship,the scores of clinical consultation,Physical examination,humanistic medicine,clinical diagnosis,health consultation,organizational effect,and overall evaluation of the experimental group were significantly improved and were higher than those of the control group.After the Practice,in terms of skill test scores,the experimental group scored higher than the control group,the difference was statistically significant(P<0.05),and the experimental group also scored higher in satisfaction evaluation than the control group.Conclusion The Mini-CEX evaluation teaching model based on the concept of OBE is applied to the clinical practice teaching of the neurology department,which can enhance the training effect of students'clinical practice skills.

Background and aim:A genome-wide association study has indicated the association of numerous genes in the 6p21.3 region with chronic hepatitis B virus(HBV)infection.In this study,we screened 12 representative single-nucleotide polymorphisms(SNPs)from the 6p21.3 region and investigated their association with the risk of chronic hepatitis B(CHB)to better understand the molecular etiology un-derlying CHB risk in the Han Chinese population. Methods:Between March 2021 and November 2022,we included 183 patients with CHB(case group)and 196 with natural HBV clearance(control group).Allele typing of the selected SNPs was performed using snapshot technology.The correlation between the 12 chosen SNPs and the risk of chronic HBV infection was examined using binary logistic regression analysis.Interacting genes of the variants were identified,and expression quantitative trait loci(eQTL)were analyzed using the 3DSNP database. Results:We validated 12 previously reported CHB susceptibility sites,including rs1419881 of tran-scription factor 19(TCF19),rs3130542 and rs2853953 of human leukocyte antigen(HLA)-C,rs652888 of euchromatic histone-lysine-methyltransferase 2(EHMT2),rs2856718,rs9276370,rs7756516,and rs7453920 of HLA-DQ,rs378352 of HLA-DOA,and rs3077,rs9277535,and rs9366816 of HLA-DP.Logistic regression analyses revealed that polymorphisms such as rs9276370,rs7756516,rs7453920,rs3077,rs9277535,and rs9366816 were positively correlated with natural HBV clearance in the dominant model.Conversely,rs3130542 and rs378352 were identified as risk factors for CHB.Haplotype analysis revealed that rs9276370,rs7756516,and rs7453920 in HLA-DQ were TTG and GCA haplotypes.Although the TTG haplotype was positively correlated with a higher risk of CHB,the GCA haplotype significantly influenced the natural clearance of HBV.Bioinformatics analysis demonstrated that rs378352,rs3077,and rs9366816 were located within enhancer states;rs3077 and rs9366816 overlapped with nine tran-scription factor-binding sites,whereas rs378352 altered five sequence motifs.Furthermore,eQTL analysis demonstrated the functional tendencies of eight statistically significant SNPs(rs3130542,rs9276370,rs7756516,rs7453920,rs378352,rs3077,rs9277535,and rs9366816). Conclusions:Genetic variations within the 6p21.3 region were associated with chronic HBV infection in the Han Chinese population in southern China.Furthermore,the GCA haplotype including rs9276370,rs7756516,and rs7453920 of HLA-DQ contributed significantly to natural HBV clearance,implying that multiple SNPs exert a cumulative allelic effect on HBV infection.

Objective:To evaluate the effect of sugammadex on the long-term prognosis in the patients undergoing kidney transplantation.Methods:American Society of Anesthesiologists Physical Status classification Ⅲ or Ⅳ patients of either sex, aged 18-64 yr, underwent donation after cardiac death renal transplantation from January 1, 2018 to October 31, 2021, were included in this study. Their clinical data were retrospectively analyzed, and then the patients were divided into 2 groups: sugammadex group (group S) and control group (group C). The complications at 1 yr after surgery and patient/graft survival at 1 and 3 yr after surgery were recorded.Results:A total of 645 patients were finally enrolled in this study, with 319 patients in group S and 326 patients in group C. There was no significant difference in the incidence of postoperative complications within 1 yr after surgery between two groups ( P>0.05). The overall patient survival rate at 1 and 3 yr after surgery were 94.7% and 92.8% respectively, and the death-censored graft survival at 1 and 3 yr after surgery were 94.4% and 89.4% respectively in group S. The overall patient survival rate at 1 and 3 yr after surgery were 96.6% and 94.7% respectively, and the death-censored graft survival at 1 and 3 yr after surgery were 93.9% and 88.6% respectively in group C. There was no significant difference in patient/graft survival rate between two groups ( P>0.05). Conclusions:Sugammadex has no obvious effect on the long-term prognosis in the patients undergoing kidney transplantation.

Objective:To investigate the clinical characteristics of patients with rheumatic diseases and abnormal liver function, as well as determine the proportion and severity of liver function abnormalities.Methods:Cross-sectional study. Data were collected from patients registered in the Chinese Rheumatism Date Center from 2011 to 2021. The rheumatic diseases analyzed in this study were rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjogren syndrome (SS), ankylosing spondylitis (AS), and gout. Patient data, including demographic characteristics [ such as age, sex, body mass index,(BMI), and smoking history], liver function test results [including alanine aminotransferase (ALT), aspartate aminotransferase, alkaline phosphatase(ALP), and total bilirubin], and use of anti-rheumatic immune drugs and liver-protective drugs, were collected and compared between groups with normal and abnormal liver functions. In addition, the proportions of abnormal liver function were compared between sex and age groups.Results:A total of 116 308 patients were included in this study, including 49 659 with RA, 17 597 with SLE, 9 039 with SS, 11 321 with AS, and 28 692 with gout. The lowest proportion of liver function abnormalities was observed in patients with RA[11.02% (5 470/49 659)], followed by those with SS[17.97% (1 624/9 039)] and AS [18.22% (2 063/11 321) ], whereas patients with SLE [21.14% (3 720/17 597) ] and gout [28.73% (8 242/28 692)] exhibited the highest proportion of these abnormalities. Elevated ALT, mostly classified as grade 1, was the most commonly noted liver function abnormality, whereas elevated ALP was the least common. Some patients who took liver-protective drugs had normal liver function, with the lowest percentage observed in patients with gout [7.45% (36/483) ] and ranging from 21.7% to 30.34% in patients with RA, SLE, SS, and AS. The proportion of liver function abnormalities was higher in males than in females for all disease types [RA: 13.8%(1 368/9 906) vs. 10.3%(4 102/39 753); SLE: 33.6% (479/1 424) vs. 20.0% (3 241/16 173); SS: 25.4%(111/437) vs. 17.6%(1 513/8 602); AS: 20.1%(1 629/8 119) vs. 13.6% (434/3 202); and gout: 29.3% (8 033/27 394) vs. 16.1% (209/1 298)]. In RA, SLE, and AS, the proportions of liver function abnormalities were similar across all age groups. In SS, the proportion of liver function abnormalities increased with age [<40 years: 14.9%(294/1 979); 40-59 years: 18.1%(858/4 741); ≥60 years: 20.4%(472/2 319)], whereas a reversal of this trend was observed in gout [<40 years: 34.9%(4 294/12 320); 40-59 years: 25.5%(2 905/11 398);≥60 years: 21.0%(1 042/4 971)].Conclusions:The proportions of combined liver function abnormalities in patients with rheumatologic diseases were high, and the utilization rates of liver-protective drugs were low. It is necessary to pay more attention to monitoring patients′ liver function, timely administer liver-protective drugs, and optimize liver-protective regimens during the treatment of rheumatic diseases.

BACKGROUND: The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts. METHODS: Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts. RESULTS: In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use. CONCLUSIONS Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.

Objective:To explore the short-term efficacy and safety of intra-arterial thrombolysis (IAT) in the treatment of retinal artery occlusion (RAO) with the assistance of the rescue green channel in the eye stroke center.Methods:A prospective, interventional, single-center study. Thirty-eight eyes from 38 RAO patients who received IAT treatment in Guangdong Provincial People’s Hospital were enrolled. All the patients were rescued via the green channel in our eye stroke center. Data from comprehensive ocular examinations including best-corrected visual acuity (BCVA) and optical coherence tomography angiography (OCTA) were collected. BCVA was measured with Snellen chart and converted to the logarithmic minimum angle of resolution (logMAR) unit for statistical analysis. RTVue XR OCTA was used to measure vascular densities (VD) of the superficial capillary plexus (SCP), deep capillary plexus (DCP) and radial peripapillary capillary (RPC), and central retinal thickness (CRT). All RAO eyes attempted IAT treatment and 34 eyes were successful. Four eyes failed to complete IAT because of the occlusion of internal or common carotid arteries on the same side with the RAO eyes. Ocular examinations in post-operative 1-3 days were performed with the same devices and methods as those before surgery. Parameters measured before and after surgery include BCVA, VD of SCP, DCP, RPC, and CRT. Data of the green channel collected include the time intervals from onset of RAO to first presentation in local hospitals, and from onset of RAO to our eye stroke center. Comparisons of VD and CRT between the RAO eyes and contralateral healthy eyes were performed with independent samples Mann-Whitney U test; comparisons of VD and CRT in RAO eyes before and after IAT surgery were performed with paired samples Wilcoxon Rank Sum test. Results:Among the 34 RAO patients who had successful IAT surgery, 18 (52.9%, 18/34) were males and 16 (47.1%, 16/34) were females; the mean age was (51.0±12.9) years old. There were 30 and 4 eyes diagnosed as central RAO and branch RAO respectively. The logMAR BCVA before and after IAT surgery was 2.52±0.61 and 2.18±0.85 respectively, and the difference was statistically significant ( Z=-3.453, P=0.002). Before surgery, VD of SCP, DCP and RPC were significantly decreased and CRT was significantly increased in the affected eye compared with the contralateral healthy eyes, with the statistical significance ( P<0.001). Compared with those before surgery, the VD of SCP and DCP were significantly improved after surgery ( Z=-2.523, -2.427; P=0.010, 0.014), while there was no difference in VD of RPC and CRT ( Z=-1.448, -1.454; P=0.150, 0.159). The time interval between onset of RAO and first visit to the hospital was (6.56±6.73) hours; the time interval between onset of RAO and the arrival at our hospital was (24.11±19.90) hours. No cerebral stroke was observed in the early postoperative period and no cerebrocardiovascular events were observed later. he time interval between onset of RAO and the arrival at our hospital was (24.11±19.90) hours. No cerebral stroke was observed in the early postoperative period and no cerebrocardiovascular events were observed later. Conclusions:The short-term efficacy and safety of IAT in the treatment of RAO were satisfactory. The rescue time window might be prolonged.

In 2016, a national one million general population cohort project was set up in China for the first time in "Precision Medicine Research" Key Project, National Key Research and Development Program of China, which consists of general population cohorts in seven areas in China. As one of the seven major areas in China, northeastern China has unique climate and specific dietary patterns, and population aging is serious in this area. And the burden of chronic and non-communicable diseases ranks tops in China. Therefore, it is of great significance to establish a large general population cohort in northeastern China to explore the area specific exposure factors related to pathogenesis and prognosis of chronic and non-communicable diseases, develop new prevention strategies to reduce the burden of the diseases and improve the population health in northeastern China. In July 2018, the general population cohort study in northeastern China was launched, the study includes questionnaire survey, health examination and blood, urine and stool sample collection and detection in recruited participants. By now, the cohort has covered all age groups, and the baseline data of 115 414 persons have been collected. This paper summarizes the design and practice of the general population cohort study in northeastern China to provide reference for related research in China.

Objective:To analyze the epidemiologic characteristics of environmental samples of avian influenza virus in Fujian province from 2017 to 2021, and provide a reference for the prevention and control of avian influenza.Methods:Six types of specimens were collected from four types of environments in six cities in Fujian province. And the specimens were subjected to nucleic acid detection for influenza A, subtypes H5, H7 and H9 by fluorescence quantitative PCR, and the results were analyzed statistically with descriptive epidemiological methods.Results:From 2017 to 2021, a total of 4 214 samples were collected from 6 cities, of which the positive rate of avian influenza virus was 41.53%, and the positive rates of H5, H7 and H9 subtypes were 2.33%, 1.16% and 23.16%, respectively. The positive rate for mixed subtypes of H5 and H7 was 0.05%, the positive rate for mixed subtypes of H5 and H9 was 1.83%, the positive rate for mixed subtypes of H7 and H9 was 0.83%, the positive rate for mixed subtypes of H5, H7 and H9 was 0.09%, and the positive rate of A-type unclassified was 12.08%. The difference in avian influenza virus detection among different monitoring places ( χ2=517.57, P<0.001), different types of specimens( χ2= 51.58, P<0.001), and different cities ( χ2=458.34, P<0.001) was statistically significant. Among different monitoring places, the positive rate of avian influenza virus in urban and rural live poultry markets was the highest. The highest rate of positive detection was found in specimens from the cage surface, cleaning poultry sewage and poultry chopping board surface, with 48.09%, 47.34% and 45.66%, respectively. In terms of different cities, Sanming city had the highest positivity rate (56.00%), while Zhangzhou city had the lowest positivity rate(3.34%). And the positive rate was higher from November to February of the next year and June to August each year. Conclusions:The overall positive rate of avian influenza viruses in Fujian province was relatively high, with H9 subtype accounting for the main proportion. The monitoring of avian influenza viruses in winter, spring and summer should be strengthened. And effective measures should be taken to deal with avian influenza especially in urban and rural live poultry markets.

Objective:To compare the hemostatic effects and patient comfort of different compression methods for hemostasis after transradial coronary intervention.Methods:A total of 160 patients who received transradial coronary intervention in The Affiliated Hospital of Hangzhou Normal University from October 2018 to February 2020 were included in this study. In group A ( n = 80), patients underwent spiral compression at the puncture point (release for 1 turn at 2 hours after surgery, rotation for 1 circle after 1 hour, and full decompression). In group B ( n = 80), patients underwent spiral compression at the puncture point (release for 1 turn at 2 hours after surgery, rotation for 1 circle after 2 hours, and full decompression). Percutaneous arterial oxygen saturation value in the affected limb, heart rate, and Visual Analog Scale score at different times after surgery, pain and comfort score at 2 and 12 hours post-surgery were compared between the two groups. Results:Percutaneous arterial oxygen saturation value at 4 and 12 hours post-surgery in group A was (96.6 ± 0.7)% and (97.8 ± 0.5)%, respectively, which was significantly higher than that in group B [(96.2 ± 0.6)%, (97.6 ± 0.7)%, t = 3.88, 2.08, both P < 0.05]. There were no significant differences in total score and subscale score of the General Comfort Questionnaire at 2 hours post-surgery between groups A and B (both P < 0.05). At 12 hours post-surgery, scores of psychological and physical subscales and total score of the General Comfort Questionnaire in group A were (23.64 ± 3.02) points, (12.64 ± 2.05) points, (68.25 ± 6.04) points, which were significantly higher than those in group B [(22.20 ± 2.96) points, (11.38 ± 2.47) points, (64.42 ± 6.71) points, t = 3.05, 3.51, 3.79, all P < 0.05]. At 2 hours post-surgery, there was no significant difference in Numerical Rating Scale score between groups A and B ( P > 0.05). At 4 and 12 hours post-surgery, Numerical Rating Scale score in group A was (2.51 ± 0.58) points and (1.75 ± 0.76) points, respectively, which was significantly lower than that in group B [(2.95 ± 0.63) points, (2.31 ± 0.71) points, t = -4.59, -4.82, both P < 0.05). The incidence of complications was significantly lower in group A than in group B (8.75% vs. 20.00%, χ2 = 4.11, P < 0.05). Conclusion:Compression for hemostasis is highly effective by releasing for 1 turn at 2 hours after transradial coronary intervention, rotating for 1 circle after 1 hour, and full compression because it can greatly mitigate pain, ensure the oxygen supply to the affected limbs, and improve patient comfort.

Objective:To evaluate the effect of controlled low central venous pressure with milrinone on laparoscopic hepatectomy in the patients.Methods:Fifty American Society of Anesthesiologists physical statusⅠ-Ⅲ patients of both sexes, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of Child-Pugh grade A or B, undergoing elective laparoscopic hepatectomy, were divided into 2 groups ( n=25 each) using a random number table method: milrinone group (group M) and nitroglycerin group (group NG). After the start of surgery, milrinone 0.5 μg·kg -1·min -1 was continuously infused in group M, and nitroglycerin was continuously infused with the initial dose of 0.5 μg·kg -1·min -1 to maintain central venous pressure (CVP)≤5 mmHg in group NG.Mean arterial pressure and heart rate were recorded on admission to the operation room (T 0), at skin incision (T 1), at the beginning of liver resection (T 2), at completion of liver resection (T 3), at the end of operation (T 4), and CVP, cardiac index and stroke volume variation were recorded at T 1-4.Internal jugular vein blood samples were collected to determine the concentrations of hemogloblin, blood lactate at T 1 and T 4, and serum alanine aminotransferase, aspartate aminotransferase and creatinine concentrations at 1, 3 and 7 days after surgery.The score of blood oozing in hepatic surgical field, amount of norepinephrine used, blood loss, postoperative recovery and occurrence of complications within 7 days after operation were recorded. Results:Compared with group NG, cardiac index was significantly increased at T 2, 3, the CVP was decreased at T 2, the blood oozing score, blood loss, consumption of norepinephrine, and concentrations of blood lactate were decreased, and the postoperative drainage indwelling time was shortened in group M ( P<0.05). There was no significant difference in the serum alanine aminotransferase, aspartate aminotransferase and creatinine concentrations and incidence of postoperative complications at 1, 3 and 7 days after operation between the two groups ( P>0.05). Conclusions:Milrinone is better than nitroglycerin in decreasing central venous pressure, reducing blood loss, maintaining stable circulatory function and tissue perfusion in laparoscopic hepatectomy.
