Abstract
Chronic obstructive pulmonary disease (COPD) is one of the chronic diseases with high morbidity and mortality in China, which imposes heavy economic burden on society. Research has shown that chronic mucus hypersecretion (CMH) is an independent risk factor for persistent clinical symptoms, poor quality of life, rapid decline in lung function, acute exacerbation and increased hospitalization rate in COPD patients. CMH is a clinical phenotype of COPD with specific pathological and physiological changes. At present, the formation mechanism of CMH is not clear. There is a lack of specific and effective targeted treatments. This article aimed to review the latest research findings on CMH at home and abroad from the overview, impact on COPD patients, molecular mechanisms of formation, current treatment status and progress, and discuss potential targets for CMH treatment, to provide new ideas and directions for improving CMH and treating COPD.

Abstract
Tooth resorption is an idiopathic destructive disease of dental hard tissues. The etiology and pathogenesis remain obscure. It has various manifestations and can be commonly classified as internal tooth resorption and external root resorption on the basis of the resorptive lesion sites. There have been many attempts to make further classification based upon the pathological manifestations in recent years. Radiographic examination is an effective tool to assist in the diagnosis. There are few systematic researches on tooth resorption worldwide, most of which are case reports. This review elaborates on the research progress of tooth resorption from aspects of pathogenesis and classification.

Abstract
Objective: To explore the association between weight gain during the first half of pregnancy and the risk of hypertension disorder of pregnancy (HDP). Methods: This prospective cohort study recruited singleton pregnant women in the first trimester from November 2016 to March 2019 at 19 community hospitals in Tianjin. According to pre-pregnancy body mass index (BMI), the cohort was divided into 3 groups: underweight(BMI<18.5 kg/m2), normal-weight(18.5-24.9 kg/m2), and overweight/obese(≥25.0 kg/m2). The basic information of the participants was gathered through questionnaires, and the height, weight, and blood pressure of the participants were measured along with routine pregnancy examinations. The rate of gestational weight gain (rGWG) in the 3 periods (0-13+6, 14+0-20+6, and 0-20+6 weeks) of the participants was calculated. To observe the occurrence of HDP, the participants were followed up to 42 days postpartum. Using a generalized linear model, the association between rGWG at the 3 periods during the first half of pregnancy and HDP after 20 weeks of gestation was evaluated. Results: A total of 9 805 pregnant women were finally included, with the age of (30.6±3.8) years old, 9 418 (96.1%) Han ethnicity, and 6 845 (69.8%) primipara. There were 1 184 (12.1%), 6 831 (69.7%) and 1 790 (18.3%) participants in the underweight, normal-weight, and overweight/obese groups. Five hundreds and eight pregnant women were diagnosed with HDP (5.2%). The incidences of HDP were 1.8% (21/1 184), 3.9% (269/6 831), and 12.2% (218/1 790), respectively, in underweight, normal-weight, and overweight/obese groups. Adjusted for age, pre-pregnancy BMI, primipara, and family history of hypertension, women in the entire cohort with rGWG ≥ 0.18 kg/week before 13+6 weeks of pregnancy had a 28% higher HDP risk than those with rGWG ≤ 0.00 kg/week (RR=1.28, 95%CI 1.04-1.55, P=0.015), and the risk of HDP was increased by 39% in the overweight/obese group (RR=1.39, 95%CI 1.04-1.85, P=0.026), while no correlation was found between rGWG and HDP in underweight and normal-weight pregnant women (P>0.05). Weight gain during 14+0-20+6 weeks of pregnancy in any group was not related to the risk of HDP (P>0.05).In the entire cohort, compared to rGWG ≤0.14 kg/week, rGWG≥0.28 kg/week prior to 20+6 weeks increased HDP risk by 36% (RR=1.36, 95%CI 1.11-1.67, P=0.003). Normal-weight pregnant women with rGWG≥0.29 kg/week faced a 46% higher risk of HDP than those with rGWG≤0.15 kg/week (RR=1.46, 95%CI 1.11-1.93, P=0.008).In the overweight/obese group, excessive weight gain before 20+6 weeks seemed to increased risk of HDP, but the difference was not statistically significant (RR=1.35,95%CI 0.99-1.85, P=0.059), while the connection was nonexistent in underweight women. Conclusions: Except for pre-pregnancy underweight women, excessive weight gain during the first half of pregnancy is associated with increased risk of HDP among pregnant women.

Abstract
Bacillus subtilis is one of the most popular commercial probiotics used in farm animal production. However, its potential mechanisms are not very clear. The aim of this study was to investigate the effects of dietary Bacillus subtilis on intestinal histomorphology, innate immunity, microbiota composition, transcriptomics, and related metabolomics. Twenty-four 48-week-old Lohman Pink-shell laying hens were randomly divided into two groups: a basic diet and the basic diet supplemented with Bacillus subtilis (0.5 g/kg) for a 9-week experiment. At the end of the experiment, tissues of the duodenum, ileum, and jejunum as well as cecal content of each bird were collected for microstructure, PCR, transcriptome, metabolome, and 16S rRNA analyses. The results showed that dietary Bacillus subtilis supplement had no effect on the intestinal microstructure. However, Bacillus subtilis increased mRNA expression of tight junction protein occludin (P < 0.05), while reduced mRNA expression of lipopolysaccharide-induced TNF factor (P < 0.01) in the duodenum. Moreover, transcriptomic results indicated that most of Bacillus subtilis supplement-induced differential genes were associated with inflammation and immunity, including cytochrome b-245 beta chain, transferrin, and purinergic receptor P2X 7, resulting in a decrease in Malondialdehyde level (P < 0.05) in the duodenum. In addition, at the genus level, Bacillus subtilis supplement enriched the potential beneficial bacteria, Candidatus_Soleaferrea (P = 0.02) but inhibited the harmful bacteria including Lachnospiraceae_FCS020_group, Ruminiclostridium, Lachnospiraceae_UCG-010, and Oxalobacter. Metabolomic results revealed that N-Acetylneuraminic acid and ADP were increased by fed Bacillus subtilis. These results suggest that dietary Bacillus subtilis could inhibit gut inflammation and improve antioxidative status and barrier integrity of the duodenum via regulating gut microbial composition in laying hens.

Abstract
Regenerative endodontic therapy is a tissue engineering based approach of treatment for endodontic disease. Its purpose is to achieve the regeneration of the pulp-dentin complex, thus to promote root development of the immature permanent tooth with necrotic pulp. Like other treatments based on tissue engineering techniques, the success of regenerative pulp therapy depends on such three elements as seed cells, scaffold materials and growth factors. Since its inception 20 years ago, there have been various terminologies in the literature, with similarities and differences in connotation. The present article summarizes and analyzes the term evolution, biological basis, clinical considerations and future scientific research directions of regenerative endodontics, in order to find out the unsolved scientific problems and to promote the development and standardization of this technique in clinical practice.

Abstract
Mussle foot protein has a main component which is named dopa. Dopa can be used to promote a relatively firm adhesion of mussels to the surface of solid materials through forming dihydrogen bonds, π-π/π-cation bonds and chelating metals,etc. To exploit these interactions, there is the opportunity to apply dopa-inspired compounds to improve the dentin-resin bonding. The current review provides valuable information concerning the mechanism of adhesion mediated by mussel foot protein and describes the application of dopa-inspired compounds in the dentin-resin bonding. The article provides novel information for future research in optimization of the properties of dentin-resin bonding.

Abstract
Cu-based catalysts have been widely used for water-gas shift reaction (WGS, CO + H2O → CO2 + H2), and α-MoC support also shows the good performance for the reaction. Therefore, WGS reaction is systematically studied over Cu/α-MoC by using density functional theory (DFT). DFT result shows the strong metal-support interaction between Cu and α-MoC(111) support. As a result, an extensive tensile strain is introduced in the Cu lattice due to α-MoC support, and Cu 3d band center shifts to Fermi level. However, the strong metal-support interaction does not lead to significant polarization of the Cu/α-MoC surface due to the less charge transfer from Mo to Cu. For the WGS reaction, small Cu particles on α-MoC(111) are likely to facilitate the reaction. At the interface of Cu-α-MoC(111), oxygen stabilizes the dissociated *H, which is benefit of H2O scission. Then, the activity increases compared with Cu(111) surface. In general, small Cu particles on α-MoC support also have good activity for WGS reaction compared with Au deposition on α-MoC. Graphical abstract.

Abstract
Objective: To explore the significance of penile index in the diagnosis of concealed penis and the evaluation of therapeutic efficacy. Methods: A retrospective study was conducted on 221 children with phimosis and 113 children with concealed penis aged 6-10, all of whom had undergone circumcision or phalloplasty respectively in Shanghai Children's Medical Center from January 2014 to December 2017. Penile index was measured before and after surgery. The values of phimosis and concealed penis were tested by group t test. Self -control test was performed for values of concealed penis before and after operations. Results: Penile index was 0.78±0.08 in children with phimosis. It was 0.23±0.10 in concealed penis before operation and changed to 0.84±0.11 postoperatively. In children with phimosis and concealed penile, the difference of penile index was statistically significant (P<0.001). The difference of penile index before and after operation was statistically significant (P<0.001) in children with concealed penis. Conclusion: Penile index is an effective index to evaluate the degree of penis exposure.

Abstract
Objective: To explore the differences of one year death and stroke recurrence between ischemic stroke patients with intracranial atherosclerotic stenosis or occlusion of anterior circulation and those of posterior circulation. Methods: All the patients were from the Chinese Intracranial Atherosclerosis Study (CICAS), between October 2007 and June 2009; patients with extracranial stenosis or occlusion, patients without acute infarction by diffusion weighted image, and patients with intracranial atherosclerosis of both anterior and posterior circulation were excluded.All the enrolled patients were divided into three groups: no significant intracranial atherosclerosis group (n=964), anterior circulation intracranial atherosclerosis group (n=440), posterior circulation intracranial atherosclerosis group (n=233). One year outcome was evaluated by any cause of death and stroke recurrence. Results: Of the 1 637 patients, 30 cases were died and 58 cases had stroke recurrence within one year.Compared with : no significant intracranial atherosclerosis group, adjusted hazard ratio (95% confidence interval) of one-year death for anterior and posterior circulation intracranial atherosclerosis group were 1.349 (0.311-5.851), 4.542 (1.227-16.813), respectively.Adjusted hazard ratio (95% confidence interval) of one year stroke recurrence were 1.663 (0.620-4.460) and 2.464 (0.935-6.493), respectively. Conclusions: Ischemic stroke patients with intracranial atherosclerosis of posterior circulation has higher risk of one year death. One year stroke recurrence risk for patients with intracranial atherosclerosis of anterior and posterior circulation needs to be further evaluated.

OBJECTIVE To compare the effects of three root canal sealers with respect to time on biocompatibility of human periodontal ligament cells (hPDLCs).The sealers included zinc oxide and eugenol based sealers (ZOE), epoxy resin sealers (ERS) and silicone based sealers (SBS). METHODS hPDLCs were primarily cultured,with the method combining of tissue explant and enzymatic digestion. The cells were then exposed to different extract fluids: (1) ZOE extracted for 24 h group ;(2) ZOE extracted for 1 week group;(3)ZOE extracted for 2 weeks group;(4) ERS extracted after 24 h group; (5) ERS extracted after 1 week group; (6) ERS extracted after 2 weeks group; (7) SBS extracted after 24 h group; (8) SBS extracted after 1 week group; (9) SBS extracted after 2 weeks group; (10) Dulbecco modified Eagle's medium/F12 (DMEM/F12) as negative control group. Cell morphology was observed under an inverted microscope.Cell proliferation was measured by methyl-thiazol-diphenyltetrazolium (MTT) assay. ALP assay kit was used for measuring alkaline phosphatase (ALP) activity. Sealers of 2 weeks' setting time were then immersed in an osteogenic medium for examination of mineral nodules and calcium deposits. RESULTS Considering the relative growth rate(RGR),ZOE was severely to moderately cytotoxic(RGR:13.6%-39.9%), while ERS was slightly or not cytotoxic (RGR: 87.6%-95.3%).Only SBS did not show any cytotoxicity after setting (RGR: 91.8%-106.7%). The setting time influenced the cytotoxicity of ERS which decreased after 1 week. Considering the ALP activity,there was no difference between SBS group and control group (F=3.397,P=0.053). According to the results of calcium deposits, ZOE:D562 nm=0.180±0.050,ERS: D562 nm=2.968±0.201,SBS:D562 nm=3.623±0.039,Control:D562 nm=3.477±0.102,the ranking of ALP activity and calcium deposits was as follows: ZOE<ERS <SBS=Control. CONCLUSION The cytotoxicity of ZOE was the highest and persisted with time. The setting time had influence on the cytotoxicity of ERS. Only SBS did not show any cytotoxicity or inhibition of the mineral potential on hPDLCs, indicating which was more biocompatible than the others.

Abstract
This study attempted to research the protective effects of cilazapril, a new ACE inhibitor, on chronic hypoxic pulmonary hypertension and hypoxemia in rats. The mean pulmonary arterial pressure (mPAP) of the rats after hypoxia and injection with 1% Fecl3 via the tail veins for 4 weeks increased significantly but its PaO2 decreased separately. Cilazapril effectively protected mPAP increase and PaO2 decrease in rats treated with Cilazapril (0.5 mg/d) by suppressing the lung injury of TNF and oxygen free radical.
