BACKGROUND: Changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels may not fully translate into patient-reported health status in patients with heart failure (HF). We aimed to evaluate the correlation between NT-proBNP levels and patient-reported health status changes at one month after discharge of patients, and their associations with risk of death and rehospitalization in patients with acute HF. METHODS: We used data from the China Patient-centered Evaluative Assessment of Cardiac Events Prospective Heart Failure Study (PEACE 5p-HF Study). Patient-reported health status was measured by the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Patients who were hospitalized for HF and completed the KCCQ-12 and NT-proBNP tests before and one month after discharge were eligible in our study. We stratified patients into different groups based on NT-proBNP levels (i.e., improved, stable, and deteriorated) and KCCQ-12 scores (i.e., not deteriorated and deteriorated). We also examined the associations of the joint NT-proBNP and KCCQ-12 change with the risk of one-year and four-year clinical outcomes. RESULTS: A total of 2461 patients were included in the analysis. The mean age was 64.06 ± 13.51 years, and 36.37% (895/2461) of the study population were female. Among patients with improved NT-proBNP levels, 115 (10.95%) patients had deteriorated KCCQ-12 scores. The correlation between the change in the KCCQ-12 score and NT-proBNP level was weak ( r2 = 0.002, P = 0.013). Stratification by changes in the KCCQ-12 score revealed subgroups with distinctive risks, such that patients with deteriorated KCCQ-12 scores in any of the NT-proBNP change groups exhibited an increased risk of one-year all-cause death than participants with not deteriorated KCCQ-12 scores in any of the NT-proBNP change groups. Patients with improved NT-proBNP levels and deteriorated KCCQ-12 scores presented greater risks of one-year all-cause death (hazard ratio [HR]: 2.45, 95% confidence interval [CI]: 1.34-4.48) than patients with stable NT-proBNP levels and not deteriorated KCCQ-12 scores (HR [95% CI], 1.77 [1.25-2.53]). CONCLUSIONS: A discrepancy between changes in NT-proBNP levels and KCCQ-12 scores was common. The change in NT-proBNP levels was not sufficient to characterize critical aspects related to HF during one month after discharge of patients. Changes in the KCCQ-12 score exhibit complementary information to NT-proBNP levels for the prediction of clinical outcomes in patients with acute HF.

Objective:To develop the Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with Inflammatory Bowel Disease (IBD), and test its reliability and validity.Methods:Guided by the theory of knowledge, attitude, and practice, a preliminary draft of the scale was formed through literature review, Delphi expert consultation, and pre-survey. From May to August 2022, convenience sampling was used to select 200 IBD patients who visited the Gastroenterology Clinic of three ClassⅢ Grade A comprehensive hospitals in Jiangsu Province as the research subject for a questionnaire survey. The critical ratio method, correlation analysis method, internal consistency method, commonality and factor loadings were used for item analysis of the scale. Exploratory factor analysis, content validity index, and internal consistency reliability were applied to test the reliability and validity of the scale.Results:A total of 200 questionnaires were distributed, and 181 valid questionnaires were collected, with an effective response rate of 90.50% (181/200). The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD included three dimensions of knowledge, attitude and practice, with a total of 21 items. The content validity index at the scale level was 0.917, and the content validity index at the item level ranged from 0.833 to 1.000. Exploratory factor analysis extracted three common factors, with a cumulative variance contribution rate of 74.197%. The Cronbach's α coefficient of the total scale was 0.951, and the coefficients of each dimension were 0.914 to 0.942. The test-retest reliability coefficient of the total scale was 0.918, and the test-retest reliability coefficients of each dimension ranged from 0.737 to 0.833.Conclusions:The Fecal Microbiota Transplantation Knowledge, Attitude, and Practice Scale for Patients with IBD has good reliability and validity, which can help medical and nursing staff evaluate patients' understanding and acceptance of microbial transplantation, so as to provide a basis for personalized communication in shared decision making between doctors and patients.

Objective:To investigate the effects of fractional CO 2 laser, focused ultrasound and simple drug treatment of gynecological vulva white lesions. Methods:A prospective study was conducted on 126 patients with white lesions of the vulva admitted to Hainan Cancer Hospital from August 2018 to December 2020. They were divided into drug group, focused ultrasound group and fractional CO 2 laser group by random number table method, with 42 patients in each group. The drug group was treated with mometasone furoate cream or dexamethasone acetate cream, and the focused ultrasound group was treated with focused ultrasound; the fractional CO 2 laser group was treated with fractional CO 2 laser. The serum interleukin-2 (IL-2), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and human epidermal growth factor (EGF) levels before and after treatment, and Visual Analogue Scale (VAS) and Dermatology Life Quality Index (DLQI) scores of the three groups were compared. Results:Before treatment, there was no significant difference in the levels of IL-2, TNF-α, CRP and EGF among the three groups (all P>0.05). After treatment, the levels of IL-2, TNF-α, CRP and EGF in the three groups were significantly decreased, and the levels of IL-2, TNF-α, CRP and EGF in the focused ultrasound group and fractional CO 2 laser group were lower than those in the drug group, with statistically significant difference (all P<0.05). Before treatment, there was no significant difference in the white lesions, dry pruritus, sexual pain and chapped skin scores of the three groups (all P>0.05); After treatment, scores of all dimensions of the three groups were significantly decreased, and scores of all dimensions of the focused ultrasound group and fractional CO 2 laser were lower than those of the drug group, with statistical significance (all P<0.05). Before treatment, there was no significant difference in the scores of symptoms and feelings, daily activities and interpersonal relationship of the three groups (all P>0.05); After treatment, scores of all dimensions of the three groups were significantly decreased, and scores of all dimensions of the focused ultrasound group and fractional CO 2 laser were lower than those of the drug group, with statistical significance (all P<0.05). Conclusions:Fractional CO 2 laser has a remarkable effect in the treatment of gynecological vulva white lesions, which can reduce the level of inflammatory factors in patients, improve the pain condition, and improve the quality of life.

Objective:To analyze the results of serum erythropoietin (EPO) in adults patients with Kaschin-Beck disease (KBD) in Qinghai Province.Methods:According to the "Diagnosis of Kaschin-Beck Disease" (WS/T 207-2010), by using clinical examination and X-ray, adults over 20 years old in KBD areas of Xinghai County and Guide County, Hainan Tibetan Autonomous Prefecture, Qinghai Province, were divided into KBD case group ( n = 109) and internal control group ( n = 95) in July 2019. At the same time, healthy people were selected as external control group ( n = 90) in Xunhua County. Then 2 ml fasting cubital venous blood was collected from the target population to separate serum. The serum EPO level was determined by enzyme-linked immunosorbent assay (ELISA). Results:There was no significant difference in age and sex ratio among the 3 groups ( F = 0.73, P = 0.484; χ 2 = 1.03, P = 0.611). There was significant difference in serum EPO levels among the 3 groups [KBD case, internal and external control groups: (30.74 ± 26.23), (19.73 ± 11.53) and (10.83 ± 4.48) U/L, F = 26.51, P < 0.001]. Multiple comparisons showed that there were statistically significant differences in serum EPO levels between KBD case group and the internal and external control groups ( P < 0.05), but there was no significant difference between the internal and external control groups ( P > 0.05). Conclusions:The serum EPO level in adult KBD patients in Qinghai Province is increased significantly.

Objective:To analyze the clinical characteristics of adult Chinese patients with syncope.Methods:This is a cross-sectional survey study. Patients with preliminary diagnosis of syncope in the Emergency Department, Geriatrics and Cardiology Outpatient Department, or Syncope Unit of 37 hospitals in 19 provinces, autonomous regions and the Hong Kong Special Administrative Region from June 2018 to March 2021 were included in this study. The clinical features of these patients with syncope were analyzed.Results:A total of 4 950 consecutive patients with syncope were included in this study. The age was (56.3±16.8)years, and 2 604 cases (52.6%) were male. The most common type of syncope was neurally mediated syncope (2 345 (47.4%)), followed by cardiac syncope (1 085 (21.9%)), orthostatic hypotensive syncope (311 (6.3%)), and unexplained syncope accounted for nearly one third (1 155 (23.3%)). Predisposing syncope was more common in patients under 65 years of age(2 066(72.4%) vs. 786(27.6%),χ 2=136.5, P<0.001). Presyncope was more common in patients with neurally mediated syncope (1 972(79.0%) vs.1 908(73.9%), χ 2=17.756, P<0.001). Premonitory symptoms were more common in women(1 837(80.0%) vs. 1 863(73.0%),χ 2=33.432, P<0.001). Presyncope syndrome was more common in patients under 65 years of age (2 482(77.8%) vs. 1 218(73.4%),χ 2=17.523, P=0.001). Cyanosis was more common in ≥65 years old patients (271(18.2%) vs. 369(12.7%), χ 2=23.235, P<0.001). Urinary incontinence was more common in old patients aged ≥65 years(252(15.2%) vs. 345(10.8%), χ 2=19.313, P<0.001). Family history was more common in patients with cardiogenic syncope compared with other types of syncope (264(24.3%) vs. 754(19.5%), χ 2=11.899, P=0.001). Hypertention(1 480(30.5%)), coronary heart disease(1 057(21.4%)), atrial flutter and atrial fibrillation(359(7.2%)), second degree atrioventricular block(236(4.8%)) were common complications of syncope. The proportion of patients with coronary heart disease was significantly higher in cardiac syncope than that of other types of syncope(417(38.4%) vs. 640(16.6%), χ 2=241.376, P<0.001). Other common complications included cerebrovascular diseases (551 (11.1%)) and diabetes mellitus (632(12.8%)). Conclusions:Neurally mediated syncope is the most common syncope in adult Chinese population. Patients with predisposing conditions and premonitory conditions are younger. Presyncope is more common in women. The proportion of family history and coronary heart disease is higher in patients with cardiogenic syncope.

Objective To detect urinary bio-markers of hydroxyproline (HYP) and c-terminal telopeptide of collagen type Ⅱ (CTX-Ⅱ) among population from Kashin-Beck disease (KBD) regions in Qinghai Province,and to provide the scientific data for prevention and control of adult KBD.Methods According to the "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010),using case-control study,120 KBD patients (males 55,females 65) and 89 healthy controls (males 41,females 48) in Qinghai KBD regions were divided into case group and control group.Morning urine samples were collected.HYP and CTX-Ⅱ contents were analyzed by enzyme-linked immunosorbent assay (ELISA),then these results were corrected with creatinine.All the data were analyzed by SPSS 17.0 software.Results There was no significant difference in the age of male and female between case group and control group (t =1.813,1.131,P ＞ 0.05).The medians of urinary HYP and CTX-Ⅱ contents among male patients were 74.91 μg/μmol Cr and 630.77 ng/μmol Cr,respectively,which were higher than those of control groups (51.38 μg/μ mol Cr,401.32 ng/μmol Cr,Z =3.068,3.246,P ＜ 0.01).The medians of urinary HYP and CTX-Ⅱ contents among female patients were 91.07 μg/μmol Cr and 637.17 ng/μmol Cr,respectively,compared with those of control groups (88.37μg/μmol Cr,546.47 ng/μmol Cr),there was no significant difference in HYP content (Z =0.273,P ＞ 0.05),however,the difference in CTX-Ⅱ content was statistically significant (Z =2.002,P ＜ 0.05).Conclusion The urinary HYP contents of male patients with KBD change significantly,while the degradation of type Ⅱ collagen in male and female patients increases,and CTX-Ⅱ could reflect the metabolic changes of collagen in KBD.

Objective: To investigate the spectrum of mutations in families with benign familial neonatal-infantile epilepsy (BFNIE) . Methods: Clinical data and peripheral blood DNA samples of all BFNIE probands and their family members were collected from Peking University First Hospital between December 2012 and April 2016. Clinical phenotypes of affected members were analyzed. Genomic DNA was extracted from peripheral blood samples with standard protoco1. Mutations in PRRT2 were screened using Sanger sequencing. For families that PRRT2 mutations were not detected by Sanger sequencing, candidate gene mutations were further screened by next-generation sequencing for epilepsy. Results: A total of 7 families were collected. Of the 30 affected members, 15 were male and 15 were female. The age of epilepsy onset was from 2 days to 6 months. Genetic testing led to the identification of gene mutations in all families. One family had the PRRT2 hotspot mutation (c.649dupC). Three families had missense SCN2A mutations (c.2674G>A/p.V892I, c.2872A>G/p.M958V, and c.2627A>G/p.N876S) . Both c.2872A>G/p.M958V and c.2627A>G/p.N876S were novel SCN2A mutations. Three families had KCNQ2 mutations. Two of them had missense mutations (c.958G>A/p.V320I and c.998G>A/p.R333Q) . The KCNQ2 mutation c.958G>A/p.V320I was novel. One family had a gene deletion of KCNQ2, which also extended to the adjacent gene, CHRNA4; and the deletion involved all the exons of KCNQ2 and CHRNA4. Conclusions Mutations in KCNQ2, SCN2A, and PRRT2 are genetic causes of BFNIE in Chinese families. The detection rate for gene mutations is high in BFNIE families. KCNQ2 and SCN2A mutations are common in BFNIE families. SCN2A mutations (c.2872A>G/p.M958V and c.2627A>G/p.N876S) and KCNQ2 mutation (c.958G>A/p.V320I) are novel mutations.

Objective To investigate the gene mutations in benign familial infantile epilepsy(BFIE)in Chi-na. Methods Data of all BFIE probands and their family members were collected from Peking University First Hospital and other three hospitals between October 2006 and June 2017. Clinical phenotypes of affected members were analyzed. Genomic DNA was extracted from peripheral blood samples with standard protocol. Mutations in PRRT2 were screened using Sanger sequencing. For families that PRRT2 mutations were not detected by Sanger sequencing,candidate gene mutations were further screened by next - generation sequencing. Results A total of 71 families including 227 affected members were collected. Genetic testing led to the identification of gene mutations in 52 families (52 / 71,73. 2％). Forty - three families had PRRT2 mutations (43 / 71,60. 6％),including 40 families with frameshift mutations(hotspot mutations c. 649_650insC and c. 649delC were detected in 29 families and 6 families,respectively),one family with nonsense mutation,one family with a loss of a stop codon,and one family with a microdeletion of the gene. C. 560_561insT and c. 679C > T were novel PRRT2 mutations. Five families had SCN2A mutations. All SCN2A mutations were missense mutations(c. 668G > A,c. 752T > C,c. 1307T > C,c. 4835C > G,c. 1737C > G). Mutation c. 752T > C, c. 1307T > C,c. 4835C > G,and c. 1737C > G were novel mutations. Three families had KCNQ2 mutations. All KCNQ2 mutations were missense mutations(c. 775G > A,c. 237T > G,c. 1510C > T). Mutation c. 237T > G and c. 1510C > T were novel mutations. One family had a novel GABRA6 mutation c. 523G > T. In 71 BFIE families,16 families had mem-bers who showed paroxysmal kinesigenic dyskinesias(PKD)and subclassified as infantile convulsions with paroxysmal choreoathetosis syndrome(ICCA). Fifteen ICCA families were found having PRRT2 mutations (15 / 16,93. 8％). The remaining ICCA family was not detected with any pathogenic mutation. Conclusion There is high frequency of gene mutations in BFIE families. Mutations in KCNQ2,SCN2A,and PRRT2 are genetic causes of BFIE. PRRT2 is the main gene responsible for BFIE. GABRA6 mutation might be a new cause of BFIE.

Objective To observe the rate of iris vessels exposure and analyze its relevant factors in normal full-term neonates.Methods A retrospective study.1855 normal full term neonates,including 947 boys and 908 girls,were enrolled.The mean gestational age (GA) was (38.84±1.10) weeks and mean birth weight (BW) was (3 396.52±402.08) g.There were 1235 neonates from normal term vaginal delivery,402 cases of cesarean delivery and 218 cases of forceps delivery.All neonates were examined with hand-held portable slit lamp biomicroscopy within 1 to 3 days after birth by two trained ophthalmologist respectively.Iris vessels exposure was defined as radial red blood vessels along iris fibers.Infants were divided into iris vessels exposure group and iris vessels unexposed group according to the findings of slit lamp biomicroscopy.78 infants with iris vessels exposure were followed up for 42 days after birth till the iris vessels can't be seen under microscope.The differences between the two groups were compared for gender,mode of delivery (MOD),GA,BW and body length (BL).Multiple logistic regressions were used to determine the factors related to iris vessels exposure.Results There were 298 neonates with iris vessels exposure among 1855 neonates and the rate was 16.1％.1557 neonates (83.9％) had unexposed iris vessels.There were no different in gender (x2=0.551) and MOD (x2=3.036) between iris vessels exposure group and unexposed group (P＞0.05),while the differences in GA (x2=47.216),BW (t=4.603) and BL (t=3.936) between the two groups were statistically significant (P=0.000).Multiple logistic regression analysis revealed that only GA (β=-0.291,odds ratio=0.747,95％ confidence interval:0.656-0.85 1,P=0.000) was correlated to iris vessels exposure significantly.The iris vessels couldn't be seen in 77 of 78 infants with iris vessels exposure when followed up to 42 days.Conclusions The iris vessels exposure in normal full-term neonates is frequently observed.There is a significant inverse correlation between GA and iris vessels exposure.
