Abstract
Objective: This study aimed to analyze the trends and characteristics of early visual development in infants and young children. Methods: A prospective cohort study was conducted, including full-term infants born between 2008 and 2013 at the Maternal and Child Health Hospital in Sanhe City, Hebei Province, China. Visual acuity was assessed at three time points 42 days after birth, 9 months of age, and 18 months of age, using the Teller Acuity Card Ⅱ (TAC Ⅱ) grating visual acuity test. At 3 years of age, visual acuity was assessed using the Lea Symbols chart and converted to grating visual acuity. Visual acuity of both eyes was measured at 42 days, 9 months, and 18 months. For children at 9 and 18 months, monocular visual acuity was also assessed, while at 3 years of age, monocular visual acuity was measured. Visual acuity measurements at different time points and changes in visual acuity within each period were recorded. The visual development of the participants was analyzed and compared with previous literature results. Results: A total of 1 496 children were included in the study, including 773 males (51.67%) and 723 females (48.33%). The binocular visual acuity at 42 days, 9 months, and 18 months was 0.9 (0.6, 1.1), 6.4 (6.4, 9.6), and 9.6 (9.6, 9.6) cycles per degree (cpd), respectively, with statistically significant differences (P<0.001). Visual acuity increased by a factor of 3.21±0.70 between 42 days and 9 months, and by a factor of 0.23±0.48 between 9 and 18 months. At 9 months of age, the monocular visual acuity in the right and left eyes was 6.4 (4.8, 6.4) cpd, which remained the same at 18 months, and the median visual acuity at 3 years of age for both eyes was 18.75 cpd, with a Snellen visual acuity of 20/32 (20/40, 20/32). The differences in binocular visual acuity at each time point were not statistically significant (all P>0.05). At 9 months of age, 68.7%(633/921) of children had visual acuity of ≥6.5 cpd, which increased to 92.7%(342/369) at 18 months. Monocular visual acuity increased by a factor of 0.26±0.46 between 9 and 18 months, and by a factor of 1.36±0.52 between 18 months and 3 years. At 9 months of age, 72.01% (921 out of 1 279) of children who completed binocular visual acuity testing also underwent monocular visual acuity testing, while this proportion decreased to 35.83% (369 out of 1 030) at 18 months. Visual acuity improved with increasing age (P<0.001). The visual acuity of children at each age group in this study was higher than that reported in the literature for children in Guangzhou (P<0.001). Conclusions: The visual acuity of healthy infants and young children below 3 years of age improves with age. Visual development progresses rapidly before 9 months of age, slows down afterward, and then resumes rapid growth at 18 months of age.

Abstract
Arrhythmia is an external manifestation of cardiac electrophysiological disorder. It exists in healthy people and patients with various heart diseases, which is often associated with other cardiovascular diseases. The contraction and diastole of myocardium are inseparable from the movement of ions. There are many ion channels in the membrane and organelle membrane of myocardium. The dynamic balance of myocardial ions is vital in maintaining myocardial electrical homeostasis. Potassium ion channels that have a complex variety and a wide distribution are involved in the whole process of resting potential and action potential of cardiomyocytes. Potassium ion channels play a vital role in maintaining normal electrophysiological activity of myocardium and is one of the pathogenesis of arrhythmia. Traditional Chinese medicine(TCM)has unique advantages in treating arrhythmia for its complex active components and diverse targets. A large number of TCM preparations have definite effect on treating arrhythmia-related diseases, whose antiarrhythmic mechanism may be related to the effect on potassium channel. This article mainly reviewed the relevant studies on the active components in TCM acting on different potassium channels to provide references for clinical drug use and development.

Abstract
Objective: To explore the intraseasonal variation in mortality risk from cold temperature exposure in Shandong Province. Methods: Mortality data in Shandong province from 2013 to 2018 were collected from the cause of death surveillance system of Shandong Center for Disease Control and Prevention. The basic information mainly included the date of death, age, gender, education level, cause of death, home address, etc. The daily meteorological data from China Meteorological Data Network mainly included the grid coordinate data of 0.01°×0.01° latitude and longitude, such as daily average temperature (℃) and daily average relative humidity (%). The cold season was from November to February. The first two months were the early cold season and the last two months were the late cold season. The extreme cold temperature was defined as the 10th percentile of the temperature range of cold season. Time-stratified case crossover design with distributed lag non-linear model analyzed the association between temperature and mortality and the association between extreme low temperature and mortality in different lag days in the cold season, and compared the intraseasonal differences between early (November-December) and late (January-February) cold season. Results: The temperature ranged from -17.3 ℃ to 18.6 ℃ in Shandong Province during the cold season from 2013 to 2018, and the P10 (extreme low temperature) was -13.7 ℃. The average daily temperature in the early cold season was (3.63±4.66) ℃. The temperature in the late cold season was (-0.09±3.70) ℃. The average daily relative humidity was (63.89±14.75) % in the early cold season and (62.27±14.19) % in the late cold season. This study included 1 473 300 deaths in the cold season in Shandong Province between 2013 and 2018. There were 824 601 (55.97%) males and 349 824 (23.75%) cases aged<65 years. There were 803 691 (54.55%) deaths due to circulatory diseases and 140 415 (9.53%) deaths due to respiratory diseases. The results of DLNM showed that the cumulative OR of extreme low temperature in the four months of cold season was 1.74 (95%CI: 1.63, 1.86) with the optimal temperature of 18.6 ℃ as the reference. The cumulative OR values of early and late cold season were 1.50 (95%CI: 1.32, 1.71) and 2.56 (95%CI: 2.12, 3.09), respectively (P<0.001). The lag effect lasted for 12 d. Conclusion: There is an intraseasonal variation of the association between cold temperature and mortality risk in Shandong Province. The mortality risk related to cold temperature in the late cold season is higher than that in the early cold season.

Abstract
Objective To investigate the detection rate and influencing factors of high-risk population of cardiovascular disease in Anhui province. Methods From March 2017 to August 2019, the residents aged 35-75 years old were selected using the multi-stage stratified cluster sampling method in 8 counties and districts of Anhui Province, and questionnaire survey, anthropometric measurement, and collection of biological samples were carried out among them. Results A total of 99,821 residents in Anhui Province were finally investigated, and among them 21,426 residents were detected to be high-risk groups of cardiovascular disease. The detection rate of high-risk groups was 21.46%. According to the high-risk types, the high-risk groups can be clustered. 74.57% of them had only one high-risk type, 22.57% of them had two high-risk types, and 2.86% had three or more high-risk types. The results of Generalized Linear Mixed Model (GLMM) showed that male, age ≥45 years old, not married, occupation as a farmer, annual family income <25,000 yuan, drinking, overweight and obesity, pre-central obesity and central obesity, snoring, feeling fatigued, sleepiness, and self-reported history of diabetes were more likely to be risk factors of cardiovascular disease (all P value < 0.05). Conclusion The detection rate of high-risk groups of cardiovascular disease in Anhui Province is relatively high. Individualized intervention measures as well as comprehensive prevention and control strategies should be adopted focusing on the distribution characteristics of risk factors of high-risk groups.

Abstract
Objective: To investigate the efficacy of RCDOP (Rituximab, cyclophosphamide, liposome doxorubicin, vincristine and prednisone) regimen in patients with de novo diffuse large B-cell lymphoma (DLBCL), especially in those patients with multiple extra-nodal involvement or Bulky diseases. Methods: A total of 87 newly diagnosed DLBCL patients who received RCDOP regimen from October 2012 to October 2017 were enrolled into this study. Survival functions were estimated using the Kaplan-Meier method and compared by the log-rank test, and χ(2) tests were used for categorical data. Results: Among the 87 DLBCL patients treated with RCDOP regimen, 81 patients achieved complete remission (CR) or partial remission (PR), with ORR as 93.1%. Patients were further classified into groups, according to the risk factors, such as IPI scores, multiple extra-nodal involvement, bulky disease, age>60, tumor Ki-67>80%, elevated serum LDH level and advanced Ann Arbor stage. The progression-free survival (PFS, P=0.084) and overall survival (OS, P=0.515) had no statistical difference among the IPI low risk (0-1 score) group, intermediate risk (2-3 scores) group and high risk (4-5 scores) group. Similarly, no statistical difference were fou nd in PFS and OS of patients with extra-nodal involvements ≥2 (P=0.303 and P=0.624), with bulky disease (P=0.518 and P=0.466), with age>60 (P=0.600 and P=0.183), with elevated serum LDH level (P=0.054 and P=0.880), with advanced Ann Arbor stage (P=0.075 and P=0.286), and with tumor Ki-67 over 80% (P=0.190 and P=0.109), when compared with those of patients without these risk factors. Conclusion: RCDOP can improve the therapeutic effect and prognosis of DLBCL patients with certain high risk factors, such as intermediate and high IPI risks, multiple extra-nodal involvements, bulky disease, age over 60, elevated LDH level, advanced Ann Arbor stage and tumor Ki-67 over 80%.

Abstract
Objective: To investigate the effects and mechanism of Holothurian Glycosaminoglycan (hGAG) alone in combination with cisplatin (DDP) on apoptosis of pulmonary adenocarcinoma cell A549. Methods: A549 cells were separately treated with blank, hGAG, DDP and hGAG combined with DDP (hGAG + DDP). The cell morphology in 4 groups was observed using light microscope. CCK8 assay was used to determine the cell viability. Flow cytometry by Hoechst 33258 and AnnexinV-FITC/PI staining was applied to detect cell apoptosis. Western blot was then used to detect the protein expression of Bax, Bcl-2, survivin and caspase-3. Results: After treatment for 24 h, the inhibitory rates of A549 cells in control, hGAG, DDP and hGAG + DDP groups were 0, (19.74±5.39)%, (42.01±2.57)% and (53.89±4.58)%, respectively. Moreover, after treatment for 48 h and 72 h, the inhibitory rates in each group were 0, (23.17±4.78)% and (29.17±4.21 )%, (54.00±7.64)% and (59.35±7.31)%, as well as (77.58±4.26)% and (79.94±4.58)%, respectively. The cell viability was significantly lower in drug treatment groups compared with those in control group at the same time point (P<0.05). Hochest 33258 staining showed that no obvious apoptotic cells were detected in the control group, while apoptotic cells were visible in hGAG, cisplatin and combination groups. Flow cytometry showed that cell apoptotic rates were (2.38±0.59)%, (12.59±4.22)%, (16.36±3.63)% and (44.60±5.45)% in the control, hGAG, DDP and hGAG + DDP groups, respectively. The cell apoptosis was significantly lower in drug treatment groups compared with those in control group at the same time point (P<0.05). Furthermore, western blot results showed that the expression of Bax and caspase-3 protein was increased (P<0.05), whereas Bcl-2 and survivin was decreased (P<0.05) in the hGAG+ DDP group compared with cisplatin alone (P<0.05). Conclusions: HGAG can inhibit the proliferation and promote the apoptosis of human lung adenocarcinoma A549 cells. Meanwhile, it can strengthen the chemosensitivity of A549 cells to DDP via up-regulation of Bax, caspase-3 and down-regulation of Bcl-2 and survivin.

Abstract
Objective: To investigate the application of principal component analysis in comprehensive indicator screening for pneumoconiosis in different regions. Methods: A principal component analysis was performed for the data of 11 factors associated with the prediction of pneumoconiosis hazard and collected in the investigation on occupational health status conducted in 172 counties (districts) in Hebei, China. The degree of pneumoconiosis hazard in different regions was obtained and intuitively presented by GIS. Results: The eigenvalues of 5 principal components of pneumoconiosis were 4.103, 2.341, 0.981, 0.943, and 0.726, respectively, and the contribution values were 37.299%, 21.286%, 8.919%, 8.572%, and 6.596%, respectively. According to the comprehensive value of principal components, GIS Natural Breaks was used to divide the degree of pneumoconiosis hazard in 172 counties (districts) in Hebei into mild, moderate, and severe grades. Of all the counties, 46 had severe pneumoconiosis hazard, 69 had moderate pneumoconiosis hazard, and 57 had mild pneumoconiosis hazard, and the ranges of the score of principal components were 0.30-1.15, -0.24 to 0.27, and -0.69 to -0.25, respectively. Conclusion: Principal component analysis can optimize the comprehensive indicators for the evaluation of regional pneumoconiosis. The comprehensive score of principal components can quantify and intuitively show the degree of pneumoconiosis hazard in different regions. Tangshan, Chengde, Shijiazhuang, and Handan have the most severe pneumoconiosis hazard.

Abstract
To bring about improvements in cancer biology research and elucidate mechanism-based therapeutic targets, we studied the proteome expression profile of purified normal urothelial cells (cancer cells) and normal stromal cells (cancerous stromal cells). Based on the expression profile, biomarker discovery and the mechanisms of multi-step carcinogenesis were explored. We found that 1412/1403 unique proteins commonly appeared in 4 sets of paired cancer/normal tissue, and 1753 proteins were differentially expressed. Three hundred and forty-one proteins were repeatedly expressed in both cancer and cancer stromal cells; 358 proteins were repeatedly expressed in both normal urothelial and normal stromal cells. Among them, 186/203 proteins were specific repeat expressions in cancer/normal tissue and thought to play an important role in cancer-stroma interactions. Differential proteins were further analyzed using bioinformatic tools and compared with the published literature. GO enrichment/depletion analysis indicated that carcinogenesis involved all the biological processes and all the cellular components. Five hundred and sixty-eight differential proteins were located in the well-known biological Kyoto Encyclopedia of Genes and Genomes pathways, including metabolic pathways, ribosome spliceosome, and endocytosis. One hundred and thirty-nine of the 186 proteins that displayed specific repeat expressions in cancer tissue were located in the biological Kyoto Encyclopedia of Genes and Genomes pathways and are thought to be candidate biomarkers for targeted therapy.

Abstract
The effect of the outer surface of core/shell nanocrystals on the fluorescence quantum yield was observed for InAs/InP and InAs/CdSe core/shells (see picture). For InAs/CdSe we observed substantial enhancement of the fluorescence quantum yield compared to the InAs core, and up to two times larger than the laser dye IR-140. Such core/shell nanocrystals have potential use as biological fluorescent markers in the near IR spectral range.

Abstract
Mutants of Salmonella typhimurium defective in the proteins of the fructose operon [fruB(MH)KA], the fructose repressor (fruR), the energy-coupling enzymes of the phosphoenolpyruvate:sugar phosphotransferase system (PTS) (ptsH and ptsI), and the proteins of cyclic AMP action (cya and crp) were analyzed for their effects on cellular physiological processes and expression of the fructose operon. The fru operon consists of three structural genes: fruB(MH), which encodes the enzyme IIIFru-modulator-FPr tridomain fusion protein of the PTS; fruK, which encodes fructose-1-phosphate kinase; and fruA, which encodes enzyme IIFru of the PTS. Among the mutants analyzed were Tn10 insertion mutants and lacZ transcriptional fusion mutants. It was found that whereas a fruR::Tn10 insertion mutant, several fruB(MH)::Mu dJ and fruK::Mu dJ fusion mutants, and several ptsHI deletion mutants expressed the fru operon and beta-galactosidase at high constitutive levels, ptsH point mutants and fruA::Mu dJ fusion mutants retained inducibility. Inclusion of the wild-type fru operon in trans did not restore fructose-inducible beta-galactosidase expression in the fru::Mu dJ fusion mutants. cya and crp mutants exhibited reduced basal activities of all fru regulon enzymes, but inducibility was not impaired. Surprisingly, fruB::Mu dJ crp or cya double mutants showed over 10-fold inducibility of the depressed beta-galactosidase activity upon addition of fructose, even though this activity in the fruB::Mu dJ fusion mutants that contained the wild-type cya and crp alleles was only slightly inducible. By contrast, beta-galactosidase activity in a fruK::Mu dJ fusion mutant, which was similarly depressed by introduction of a crp or cya mutation, remained constitutive. Other experiments indicated that sugar uptake via the PTS can utilize either FPr-P or HPr-P as the phosphoryl donor, but that FPr is preferred for fructose uptake whereas HPr is preferred for uptake of the other sugars. Double mutants lacking both proteins were negative for the utilization of all sugar substrates of the PTS, were negative for the utilization of several gluconeogenic carbon sources, exhibited greatly reduced adenylate cyclase activity, and were largely nonmotile. These phenotypic properties are more extreme than those observed for tight ptsH and ptsI mutants, including mutants deleted for these genes. A biochemical explanation for this fact is proposed.
