Abstract
BACKGROUND Surgery is the most effective way to treat bromhidrosis, but postoperative complications are still the biggest obstacles for patients to choose surgical treatment. OBJECTIVES To introduce an innovative application of follicular unit extraction (FUE) in the treatment of bromhidrosis. METHODS We conducted a case series study on 20 patients who received FUE technique for the treatment of bromhidrosis. The axillary hair follicles were extracted with a one-millimetre punch. The released hair follicles were collected for histological examination. After the operation, the wounds were wrapped with moderate pressure. The dressing was removed 24 h after the FUE operation. The postoperative complications were collected, and the improvement of malodour was evaluated by the 10-point visual analogue scale. RESULTS Immediately postoperation, many needle-shaped holes appeared in the armpits. The holes healed 7 days after the operation, with no scar or pinpoint-like scars. Except for a female who complained of mild pain in the left armpit, no other patients had any discomfort. The malodour level varied between 0 and 4 during the follow-up period. The tissue examination showed that more than 90% of the completely plucked hair follicles were accompanied by apocrine glands, and many blocked and dilated apocrine glands were observed. The lumens of the blocked glands were filled with decapitation products, which were positive for K5, Brst-2 and CEA. CONCLUSIONS Patients with bromhidrosis have a positive response to FUE technique. The FUE technique is well-tolerated, with only a few postoperative complications, which deserves to be widely promoted.

Abstract
Using combined data from the Relativistic Heavy Ion and Large Hadron Colliders, we constrain the shear and bulk viscosities of quark-gluon plasma (QGP) at temperatures of ∼150-350 MeV. We use Bayesian inference to translate experimental and theoretical uncertainties into probabilistic constraints for the viscosities. With Bayesian model averaging we propagate an estimate of the model uncertainty generated by the transition from hydrodynamics to hadron transport in the plasma's final evolution stage, providing the most reliable phenomenological constraints to date on the QGP viscosities.

Predicted sensitivity to endocrine therapy for stage II-III hormone receptor-positive and HER2-negative (HR+/HER2-) breast cancer before chemo-endocrine therapy. Ann Oncol 2021; 32:642-651.

Abstract
BACKGROUND We proposed that a test for sensitivity to the adjuvant endocrine therapy component of treatment for patients with stage II-III breast cancer (SET2,3) should measure transcription related to estrogen and progesterone receptors (SETER/PR index) adjusted for a baseline prognostic index (BPI) combining clinical tumor and nodal stage with molecular subtype by RNA4 (ESR1, PGR, ERBB2, and AURKA). PATIENTS AND METHODS Patients with clinically high-risk, hormone receptor-positive (HR+), human epidermal growth factor receptor 2 (HER2)-negative (HR+/HER2-) breast cancer received neoadjuvant taxane-anthracycline chemotherapy, surgery with measurement of residual cancer burden (RCB), and then adjuvant endocrine therapy. SET2,3 was measured from pre-treatment tumor biopsies, evaluated first in an MD Anderson Cancer Center (MDACC) cohort (n = 307, 11 years' follow-up, U133A microarrays), cut point was determined, and then independent, blinded evaluation was carried out in the I-SPY2 trial (n = 268, high-risk MammaPrint result, 3.8 years' follow-up, Agilent-44K microarrays, NCI Clinical Trials ID: NCT01042379). Primary outcome measure was distant relapse-free survival. Multivariate Cox regression models tested prognostic independence of SET2,3 relative to RCB and other molecular prognostic signatures, and whether other prognostic signatures could substitute for SETER/PR or RNA4 components of SET2,3. RESULTS SET2,3 added independent prognostic information to RCB in the MDACC cohort: SET2,3 [hazard ratio (HR) 0.23, P = 0.004] and RCB (HR 1.77, P < 0.001); and the I-SPY2 trial: SET2,3 (HR 0.27, P = 0.031) and RCB (HR 1.68, P = 0.008). SET2,3 provided similar prognostic information irrespective of whether RCB-II or RCB-III after chemotherapy, and in both luminal subtypes. Conversely, RCB was most strongly prognostic in cancers with low SET2,3 status (MDACC P < 0.001, I-SPY2 P < 0.001). Other molecular signatures were not independently prognostic; they could effectively substitute for RNA4 subtype within the BPI component of SET2,3, but they could not effectively substitute for SETER/PR index. CONCLUSIONS SET2,3 added independent prognostic information to chemotherapy response (RCB) and baseline prognostic score or subtype. Approximately 40% of patients with clinically high-risk HR+/HER2- disease had high SET2,3 and could be considered for clinical trials of neoadjuvant endocrine-based treatment.

Abstract
AIM To assess the potential of texture analysis (TA) applied in T1 maps and extracellular volume (ECV) obtained using cardiac magnetic resonance (CMR) in the diagnosis of hypertrophic cardiomyopathy (HCM) and hypertensive heart disease (HHD) compared with normal controls (NC). Strain parameters were analysed to compare with final TA models. MATERIALS AND METHODS This retrospective study included 66 HCM patients, 39 HHD patients, and 41 NC. Step-wise dimension reduction and feature selection were performed by reproducibility, machine learning, collinearity, and multivariable regression analysis to select the texture features that enable diagnosis of and differentiation between HCM and HHD. Strain parameters were calculated by short-axis and three long-axis cine sequences. RESULTS Independent features in T1 maps and ECV analysis allowed for the differentiation between patients (HCM and HHD) and NC. Of the best-calculated model, the areas under the receiver operating curve (AUCs) were as follows: 0.969 for T1 map and 0.964 for ECV. To distinguish HCM from HHD, two independent features were screened out for both T1 and ECV maps. The AUCs were as follows: 0.793 for T1 map and 0.894 for ECV. Radial, circumferential, and longitudinal strain parameters could differentiate patients from NC, but only longitudinal strain parameters was significantly different between HCM and HHD. CONCLUSIONS Texture analysis of T1 maps and ECV shows high accuracy in differentiating hypertrophic myocardium from NC, and HCM from HHD. Strain parameters are able to demonstrate the difference between patients and NC, but were less impressive in differentiating HCM and HHD.

Abstract
Non-coding RNAs are a class of RNAs with multiple roles in plant life. Covalently closed circular RNA molecules (circRNAs) have been recently shown to be a group of RNA isoforms that show widespread tissue-specific expression in plants, often cooperating with the corresponding linear mRNAs to regulate gene function. However, no previous study of poplar has identified circRNAs in the cambium and determined their potential roles in the cambium or xylem development. In the present study, we sequenced RNAs in the cambium of poplar seedlings at two developmental stages, and identified and characterized 4912 circRNAs. Alternative back-splicing circularization events for 87 genes were identified among the circRNAs derived from different chromosomes. A total of 1138 circRNAs originated from 928 host genes, which were classified among the three major functional categories by GO analysis. Thirty-nine circRNAs were differentially expressed between cambium samples of stems at two developmental stages. Twenty-four DEcircRNAs interacted with 98 miRNAs as targets, of which some were associated with cambium growth and development. The results suggest that circRNAs play important roles in the cambium in relation to the regulation of stem growth and development in poplar seedlings.

Abstract
Objective: To assess the health status and health service utilization of children born to syphilis infected mothers during pregnancy, in order to prevent mother-to-child transmission of syphilis to the newborns. Methods: Women with maternal syphilis were studied by trained researchers via phone calls, in Shanghai during 2014-2015. Data related to demographics, status of infection and health care, utilization by both mothers and their children were collected through specifically designed questionnaires. Non-parametric tests including chi-square were used to assess the health status and health service utilization of children born to mothers with different demographic and socioeconomic characteristics. Results: A total of 495 children born to mothers with maternal syphilis were recruited from 1 000 syphilis infected parturient women. A total of 61 out of the 495 children were diagnosed as having congenital syphilis (57 children were diagnosed at birth and another 4 were diagnosed during the follow-up period). Children born to women who received syphilis treatment during pregnancy were at lower risk on congenital syphilis (χ(2)=7.214, P=0.027). 37.8% of the children were reported to have had different illnesses in the past three months, mainly involving upper respiratory infections (32.3%) or diarrhea (3.6%). Children diagnosed with congenital syphilis showed a higher prevalence of different kinds of diseases, compared to those without congenital syphilis (47.5% vs. 36.6%). 81.6% of the children had received regular child health care services. Subjects with the following factors as: being immigrant, with lower education, unemployed, unmarried and multipara, were related to the less use of regular child healthcare services. Only 39.7% of the parents would inform the care-takers about the risk of congenital syphilis infection of their own children at the child health care centers. Mothers with residency of Shanghai, having higher education level and employed, were less willing to inform doctors about the risk of congenital syphilis infection of their children. Conclusions: Loss to follow-up among children born to syphilis infected pregnant women remained a serious problem. Few parents would be willing to inform the healthcare takers that their children are at risk of syphilis, when receiving child health care services at the centers. It was necessary to integrate the congenital syphilis follow-up programs into the routine child care services so as to timely diagnose and treat the patients with congenital syphilis.

Abstract
Objective: To identify problems and demands for antenatal care (ANC) among pregnant women in different trimesters of pregnancy in Shanghai for optimizing ANC service during the epidemic of COVID-19. Method: s Organized by maternal and child health care institute in the 16 districts of Shanghai, a cross sectional study was conducted among pregnant women who came to pregnancy registration in the community health centers or attended ANC in midwifery hospitals from February 7 to February 12, 2020. Consented participating women completed a semi-structured online questionnaire voluntarily. Data was analyzed using frequency,chi-square test and scoring. Result: s A total of 2 002 valid questionnaires were collected from 183 community health centers and 67 midwifery hospitals. About 94.6%(1 894/2 002) of the pregnant women worried about being infected during the COVID-19 epidemic, and 14.7% (294/2 002) demanded for psychological consultation. Time-lapse appointments for ANC were requested by 87.7% (1 756/2 002) of the participants for avoiding presenting themselves in people-density places. Compared with other pregnancy trimesters, pregnant women in the second trimester were more willing to reduce the frequency of ANC (35.2% versus 39.5% versus 48.1%, P<0.01). Compared with multiparas, primiparas were more willing to have online consultation and guidance (49.2% versus 63.8%, P<0.01). Regarding the needs for health knowledge on COVID-19, personal protection against 2019 novel coronavirus (2019-nCoV) was the most concerned for pregnant women, and 71.0% (1 421/2 002) of them preferred to obtain knowledge through health applications, official Weibo and WeChat. Conclusions: Pregnant women in Shanghai critically concern about the risk of 2019-nCoV infections, and highly demand knowledge and measures on prevention and protection from COVID-19. They ask for having time-lapse appointments for ANC and online access to health information and services. Maternal and child care institutes should understand the demands of pregnant women, optimize the means of ANC service, and provide tailored and accessible health education and service for the safety of mother and child.

Abstract
This study has two targets: Studying the extraction of the initial protein content from brewer's spent grain and the impact of protein's extraction on the chemical-physical properties of produced hydrochars. The protein was extracted from brewer's spent grains using the pH-shifting method. The extracted protein was quantified and characterized by their amino acid profile. The hydrothermal treatment was applied at 190 °C and 220 °C for 0.5 h, 1 h, 2 h, and 4 h. The hydrochars and process water were collected and assayed. The hydrochar after protein extraction reveals the lowest yield to hydrochars (67.10-45.14%), higher C/N ratio (19.66-21.33) and lower ash content (1.52-1.72 wt%) compared to the hydrochar without extraction.

Abstract
During the past nine years, our center has grown into the largest uveitis referral center in China. To deal with this increasing stream of patients we have developed a management system to coordinate communication with our patients, their referring ophthalmologists, consultations with other medical specialties and worldrenowned foreign uveitis specialists. We have established the biggest database of uveitis patients records allowing continuous analysis of clinical features and response to treatment of patients with various uveitis entities as well as the evaluation of the relevance of various ancillary tests performed in this patient group. The establishment of a specimen biobank has been shown to be instrumental in the research on the complex immunopathological mechanisms involved in this disease. The close interaction between patient care and clinical research under one roof has led to a novel understanding of disease mechanisms and will undoubtedly lead to a tailored treatment for this disease.

Abstract
BACKGROUND AND AIMS Early postnatal life is a critical developmental period that affects health of the whole life. Extrauterine growth restriction (EUGR) causes cardiovascular development problems and diseases, including pulmonary arterial hypertension (PAH). PAH is characterized by proliferation, migration, and anti-apoptosis of pulmonary artery smooth muscle cells (PASMCs). However, the role of PASMCs in EUGR has not been studied. Thus, we hypothesized that PASMCs dysfunction played a role in EUGR-induced pulmonary hypertension. METHODS AND RESULTS Here we identified that postnatal nutritional restriction-induced EUGR rats exhibited an elevated mean pulmonary arterial pressure and vascular remodeling at 12 weeks old. PASMCs of EUGR rats showed increased cell proliferation and migration features. In EUGR-induced PAH rats, Notch3 signaling was activated. Relative mRNA and protein expression levels of Notch3 intracellular domain (Notch3 ICD), and Notch target gene Hey1 in PASMCs were upregulated. We further demonstrated that pharmacological inhibition of Notch3 activity by using a γ-secretase inhibitor DAPT, which blocked the cleavage of Notch proteins to ICD peptides, could effectively inhibit PASMC proliferation. Specifically knocked down of Notch3 in rat PASMCs by shRNA restored the abnormal PASMC phenotype in vitro. We found that administration of Notch signaling inhibitor DAPT could successfully reduce mean pulmonary arterial pressure in EUGR rats. CONCLUSIONS The present study demonstrated that upregulation of Notch3 signaling in PASMCs was crucial for the development of EUGR-induced PAH. Blocking Notch3-Hey1 signaling pathway in PASMCs provides a potential therapeutic target for PAH.

Abstract
The aim of this study was to determine the association between 13 single nucleotide polymorphisms (SNPs) in the cytotoxic T lymphocyte-associated antigen-4 (CTLA4) and protein tyrosine phosphatase non-receptor type 22 (PTPN22) genes with scleritis in a Chinese Han population. We recruited 432 scleritis patients and 710 healthy controls. Four tag SNPs of CTLA4 and nine tag SNPs of PTPN22 were selected using Haploview. Genotyping was performed with the Sequenom MassArray® iPLEX GOLD Assay. Genotype and allele frequency differences were analyzed by χ2 test and Bonferroni correction. Haplotype analysis was performed to further evaluate the association of these two genes with scleritis. In this study, CTLA4/rs3087243 G allele frequency and GG genotype frequency were significantly increased in scleritis patients compared to healthy controls [corrected P-value (Pc) = 0·02, odds ratio (OR) = 1·475, 95% confidence interval (CI) = 1·175-1·851; Pc = 0·04, OR = 1·546, 95% CI = 1·190-2·008, respectively]. None of the tested SNPs in the PTPN22 gene showed an association with scleritis. Haplotype analysis revealed a lower frequency of a CTLA4 TCAA haplotype (order of SNPs: rs733618, rs5742909, rs231775, rs3087243) (Pc = 4·26 × 10-3 , OR = 0·618, 95% CI = 0·540-0·858) and a higher frequency of a PTPN22 TTATACGCG haplotype (order of SNPs: rs3789604, rs150426536, rs1746853, rs1217403, rs1217406, rs3789609, rs1217414, rs3789612, rs2488457) (Pc = 2·83 × 10-4 , OR = 1·457, 95% CI = 1·210-1·754) in scleritis patients when compared to healthy controls. In conclusion, our findings indicate that CTLA4 and PTPN22 might confer genetic susceptibility to scleritis in a Chinese Han population.

Abstract
Objective: To dynamically analyze the discipline status, influence factors and key issues of Chinese Journal of Hepatology from 2010 to 2016 and explore the development rules of citation indexes. Methods: We collected information published by the China Institute of Scientific and Technological Information [China Science and Technology Journal Citation Report (Core Edition)] and Wanfang Database Periodicals statistical analysis platform from 2010 to 2016. A bibliometric analyses on article volume, citation frequency, citation rate, h-index, ratio of fund-aided papers, periodical influence, key number published period, number of relevant articles, and so on were analyzed for annual's impact factor. Results: According to the data released by the China Institute of Science and Technology Information, from 2010 to 2011, the impact factor of Chinese Journal of Hepatology was at leading level in the field of internal medicine and ranked sixth in the Journal of Internal Medicine. From 2012 to 2016, the overall comprehensive assessment score and citation frequency score of Chinese Journal of Hepatology were ranked first in the Journal of Gastroenterology. Core impact factors kept the discipline ahead. Indexes such as immediacy index, h- index, cited half-life and all other indicators were increased. Citation rate was >90% and cited issue number had greatly increased. Conclusion: Chinese Journal of Hepatology has a leading position in the Journal of Gastroenterology and credited by inland readers and authors of digestive and infectious fields. It has played a positive role in promoting the development of the discipline.
