BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To investigate the effect of laboratory indicators on hair loss in patients with female pattern hair loss (FPHL).Methods:Patients with FPHL who visited the Outpatient Clinic of the Department of Medical Aesthetics in Hangzhou First People’s Hospital from November 2022 to November 2023 were selected as the study group, and healthy women who matched the age of the study group in the physical examination center during the same period were selected as the control group. The general information of the patient was recorded, and was also tested by trichoscopy to rule out other patterns of alopecia. Representative indicators including testosterone, dehydroepiandrosterone sulfate(DHEA-S), thyroid-stimulating hormone, 25-hydroxyvitamin D, and serum ferritin were selected from laboratory tests for further analysis. Otherwise, the proportion of deficiency in vitamin D(<20 ng/ml) was calculated based on 25-hydroxyvitamin D levels (number of deficiency cases/total number of cases in each group×100%). Count data were presented as samples (percentages), and chi-square test was used for comparison between groups. Normally distributed continuous data were presented with Mean±SD, independent samples t-test was used for comparison between groups, M( Q1, Q3) was used for non-normally distributed continuous data, and Wilcoxon rank-sum test was used for comparison between groups. Multivariate logistic regression was used to analyze the influencing factors of FPHL. P<0.05 was statistically significant. Results:A total of 37 patients were selected in both groups. The mean age was (28.8±1.3) years in the study group and (29.6±0.9) years in the control group ( t=0.49, P=0.625). The body mass index was (22.8±0.4) kg/m 2 in the study group, and (23.5±0.3) kg/m 2 in the control group ( t=1.26, P=0.211). The testosterone level was 0.58 (0.49, 0.79) nmol/L in the study group, and 0.54 (0.50, 0.78) nmol/L in the control group( Z=1.42, P=0.157). The level of DHEA-S was 6.21 (5.18, 9.60) μmol/L in the study group, and 6.20 (5.20, 9.34) μmol/L in the control group ( Z=2.75, P=0.006). The level of thyroid-stimulating hormone was 2.56 (1.55, 3.66) mU/L in the study group and 1.49 (1.05, 2.65) mU/L in the control group ( Z=2.51, P=0.012). The level of 25-hydroxyvitamin D was 15.44 (11.80, 21.20) ng/ml in the study group, and the level of 25-hydroxyvitamin D was 20.32 (12.07, 21.20) ng/ml in the control group ( Z=2.30, P=0.021), and the proportion of 25-hydroxyvitamin D deficiency in the study group was 64.9% (24/37), which was higher than that in the control group [40.5% (15/37)] ( χ2=4.39, P=0.036). The serum ferritin level was 64.44 (39.47, 133.45) μg/L in the study group and 67.75 (52.63, 143.83) μg/L in the control group ( Z=0.70, P=0.484). The results of multivariate logistic regression analysis showed that the risk of FPHL was increased by the high level of DHEA-S and thyroid-stimulating hormone, and the low level of 25-hydroxyvitamin D (all P<0.05). Conclusion:Abnormal level of DHEA-S, thyroid-stimulating hormone, and 25-hydroxyvitamin D may be risk factors for FPHL.

Objective:To investigate the effect and mechanism of type ⅩⅦ collagen (COL17) on hair growth in mice with androgenetic alopecia (AGA).Methods:Forty-eight C57BL/6J mice were used to establish AGA model (the back hair of the mice was removed and dihydrotestosterone solution was applied) and divided into 6 groups of 8 mice each by random number table. Negative control group, injection of saline in the depilated area (single point injection of 0.05 ml, 5 points in total); positive control group, topical application of 5% minoxidil tincture in the depilated area, 1 ml/d; COL17 low, medium and high concentration groups, injection of 0.5, 1.0 and 2.0 mg/ml COL17 in the depilated area respectively (single point injection of 0.05 ml, 5 points in total); type Ⅲ and ⅩⅦ collagen (COL3+ COL17) combined high concentration group, injection of 2.0 mg/ml COL3 and COL17 in the depilated area (single point injection of 0.05 ml, 5 points in total). The total treatment time was 21 days, during which the hair growth of mice in each group was observed and recorded. After 21 days, the skin and subcutaneous tissue in the depilated area of the mice were taken to make pathological sections for HE staining, and the number and morphological changes of hair follicles were observed; fresh skin tissue in the depilated area of the mice was taken for total RNA sequencing analysis, and the differentially co-expressed genes were annotated by gene ontology (GO) functional annotation, Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis and gene set enrichment analysis (GSEA).Results:After 21 days of treatment, compared with the negative control group, the depilation area on the back of the mice in the positive control group, COL17 high concentration group, and COL3+ COL17 combined high concentration group was significantly reduced, and HE staining showed that the number of hair follicles was also significantly increased. Pearson correlation analysis, principal component analysis and cluster heat map between groups showed that COL17 high concentration group had high gene correlation with the positive control group ( R2=0.95, P=0.024), and the gene expression was relatively close, with 3 882 differentially expressed genes (1 705 up-regulated and 2 177 down-regulated) in the two groups, while COL3+ COL17 combined high concentration group had the highest gene correlation with the positive control group ( R2=0.96, P=0.001), and the gene expression was the closest, with 1 289 differentially expressed genes (385 up-regulated and 904 down-regulated). KEGG analysis showed that compared with the negative control group, the positive control group, COL17 high concentration group and COL3+ COL17 combined high concentration group of mice all upregulated Wnt signaling pathway, cell adhesion molecules and hedgehog signaling pathway related to hair growth. GO enrichment analysis suggested that COL17 high concentration group and COL3+ COL17 combined high concentration group had upregulated genes related to skin development and hair cycle. GSEA enrichment analysis found that COL17 high concentration group had upregulated genes related to fibroblast proliferation and interleukin-1 secretion, while COL3+ COL17 combined high concentration group had upregulated genes related to fibroblast migration, clearance of apoptotic cells and accelerated metabolism of reactive oxygen species. Conclusion:Local injection of 2.0 mg/ml COL17 has a certain promoting effect on hair growth in AGA model mice, and the effect is more significant after combined injection of 2.0 mg/ml COL3. Activation of Wnt signaling pathway is one of the main mechanisms of COL17 promoting hair growth.

Objective:To explore the applicability of the distance between facial marks classification in evaluating the severity of androgenic alopecia in men.Methods:From June to December 2019, the male Chinese with diagnosis of androgenic alopecia were evaluated in the specific clinic of alopecia of Hangzhou First People’s Hospital according to the distance between facial marks and BASP(basic and specific) classification. The classification based on the distance between facial marks measures the distance from the facial marks of the anterior hairline to the horizontal line of the eyebrow and the longest radius of hair loss in the hair rotation center, the hair recession of the patient’s forehead (F), temporal (M) and vertex (V) parts. The hair loss in each region is rated as 0-3 grade from light to heavy, and the final hair loss grading is expressed as FnMnVn, such as F1M2V0. The highest grade of hair loss in F, M and V is the overall grade of hair loss. SPSS 25.0 software was used to statistically analyze the general data of patients, and Kappa test was used to evaluate the consistency between the results of the distance classification and BASP classification. The repeatability of the distance classification was tested by the repetition rate of three hair loss specialists. When two or more specialists gave the same evaluation among the three hair loss specialists, the result was regarded as the standard result. The ease of use of the distance between facial marks classification was tested by the consistency rate between the grading results of two temporary trained general doctors and the standard results.Results:A total of 150 male patients, aged (32.8±7.9) years (19-58 years), were included, of which 99 patients were 24-35 years old, accounting for 66.00%. It can be observed that the onset age was earlier. As assessed in this classification, the patients who participated in the study were graded as mild in 65 cases(43.33%), severe in 58 cases(38.67%), and moderate, which was consistency with the results obtained by BASP classification ( κ=0.573, P<0.001). Three experienced alopecia specialists evaluated 150 patients through the distance between facial marks. The results showed that the repetition rates of frontal, temporal and parietal classification results were 98.00%(147/150), 97.33%(146/150) and 96.00%(144/150), respectively. The repetition rate of the final alopecia classification was 92.00%(138/150), and the repetition rate of the overall alopecia classification was 98.00%(147/150). The consistency rate between the overall alopecia classification results of two temporary trained general doctors and the standard results was 95.92%(141/147) and 96.60%(142/147), respectively, and the consistency rate of the other results was higher than 90.00% except for one general doctor who was 89.86%(124/138) in the final classification. Conclusion:The distance between facial marks classification is a comparatively accurate and easy-to-learn grading method designed for Chinese male androgenic hair loss patients based on objective measurement data.

Objective:To analyze the characteristics of electroencephalogram (EEG) and clinical manifestations of children with moyamoya disease (MMD), and to explore the value of EEG in the clinical diagnosis of childhood MMD.Methods:Twelve children indicated as cerebrovascular diseases by EEG and later diagnosed with MMD by head magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) in Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2012 to June 2019 were enrolled in this study.Their EEG and clinical data were retrospectively analyzed.Results:Nine cases were male and 3 cases were female, with the onset age of 3.0-8.7 years old.Ten cases were taken to the hospital because of paroxysmal limb weakness on one side or both sides, 1 case was because of paroxysmal fall, and 1 case was because of paroxysmal posture abnormalities.EEG background activities of 12 cases were normal.Interictal EEG was normal in 8 cases, borderline in 1 case, and abnormal in 3 cases (1 case had many slow waves in bilateral anterior head, and its number significantly increased during the awakening period; 1 case had a great many irregular delta slow waves on bilateral prefrontal cortex, showing significant aggravation during the awakening period; 1 case had many multifocal delta slow waves especially in the right frontopolar region). The hyperventilation (HV) induction test was abnormal, and rebuild-up of slow waves was noted in 4 cases.The focal delta slow waves (especially in the anterior head) developed to diffuse slow waves after stopping HV for 0.5 to 1.0 minutes, and lasted for 5 to 9 minutes after relief of symptoms.The delayed disappearance of asymmetric focal slow waves was noted in 8 cases.Focal slow waves (especially in anterior head) developed to diffuse slow waves at 1.5 to 2.0 minutes after HV initiation, and lasted for 5 to 10 minutes in total.Among them, 1 case pre-sented no obvious accompanying symptoms during HV, while 11 cases showed transient ischemic symptoms that were basically consistent with the chief complaint.The duration of symptoms was much shorter than the appearance of slow waves in EEG.Besides, brain MRI of 3 cases suggested local malacia lesions or abnormal signals, especially in parietal and basal ganglia areas.The high signal shadow was observed in the sulcus of bilateral cerebral hemispheres on the fluid attenuating inversion recovery sequence of one case.All of 12 cases were proved to MMD by head MRA.Conclusions:Clinical symptoms of children with MMD are paroxysmal limb weakness.Rebuild-up of slow waves or the delayed disappea-rance of focal slow waves is highly suggestive of MMD.These 2 kinds of abnormal EEG patterns sustain over long periods of time.Focal slow waves (especially in anterior head) develop to diffuse slow waves, and lastly decrease to focal slow waves in anterior head.

Objective: To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors from 2015 to 2017. Methods: A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis. Results: As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05). Conclusions From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.

BACKGROUND: Early investigation suggested patients' level of awareness regarding clinical trials was related with willingness to participation. This study was intended to evaluate the level of awareness of cancer patients regarding clinical trials and related influencing factors, and to compare the differences of awareness between patients who attended clinical trials before and not. METHODS: From Jun, 2018 to April, 2019, standardized question-naires were gathered from cancer patients (attended clinical trials vs not attended clinical trials) in our hospital regarding basic information and 10 other questions about awareness. The level of awareness was evaluated and patients were classified into "low cognition" and "high cognition" groups. Logistic regression analysis was performed to determine whether certain characteristics would predict for awareness. RESULTS: Of the 617 participants, 38.6% have attended clinical trials before. 338 (54.6%) patients had a correct overall understanding of clinical trials, while 44 (7.1%) patients still thought participants were the victim of scientific research. Except for the compensation of medical expenses (51.5% vs 48.7%) and related laws of clinical trials (52.3% vs 45.5%), other parts of understanding were elevated in patients attended clinical trials before comparing with patients who didn't, including significance (86.2% vs 77.6%), risk disclosure (91.2% vs 71.6%), confidentiality (73.2% vs 59.7%), voluntariness (95.8% vs 76.3%), withdrawal (86.6% vs 68.2%) and expenses (62.8% vs 39.2%). The proportion of participants who understand these components did not increase even in 239 patients who had attended clinical trials before. Participants who attended clinical trials before (OR=1.83, 95%CI: 1.11-3.00), unmarried/divorced (OR=5.04, 95%CI: 1.73-14.66), retired (OR=2.53, 95%CI: 1.16-5.50) had a higher level of awareness, while patients who had bad impression with doctors (OR=0.43, 95%CI: 0.26-0.72) had lower awareness. CONCLUSIONS The current level of awareness for clinical trials of cancer patients in our hospital was relatively low, even in patients who had attended clinical trials before. It's necessary to improve patients' awareness of clinical trial by promoting harmony relationship between patients and doctors, as well as by enhancing related propagation. Strengthening the adequacy and efficacy of informed consent in clinical trials also needs to be achieved in the future.
