Association Between Serum Uric Acid and Prevalence of Type 2 Diabetes Diagnosed using HbA1c Criteria Among Chinese Adults in Qingdao,China

Objective To determine whether elevated serum uric acid(UA)levels are associated with type 2 diabetes diagnosed using Hb A1 c levels among Chinese adults.Methods We conducted two population-based cross-sectional studies in Qingdao in China in 2006 and 2009.A total of 6894(39.4% men)subjects aged 35-74 years were included in the data analysis.Newly diagnosed diabetes was defined as Hb A1 c level of ≥6.5%,and prediabetes was classified as Hb A1 c level between 5.7% and 6.4% according to the International Diabetes Federation criteria.Multivariate logistic regression was employed to assess the association between UA and prevalence of type 2 diabetes defined using Glycated hemoglobin A1c(Hb A1 c levels.Results Subjects with prediabetes had higher UA levels than those with normal glucose tolerance,newly diagnosed diabetes,and known diabetes,with corresponding values of 325.1(82.5)μmol/L,310.9(84.2)μmol/L,291.3(81.7)μmol/L,305.2(83.6)μmol/L,respectively(P<0.001 for all comparisons).Binary logistic regression analysis showed that UA was a possible predictor for the prevalence of type 2 diabetes diagnosed using Hb A1 c levels,and the second quartile of UA levels had a higher odds ratio(OR:4.088;95% CI:2.900-5.765)for Hb A1 c than the other quartiles after adjusting for age,body mass index,sex,marital status,education,income,alcohol consumption,smoking,and cardiometabolic parameters.Conclusion Serum UA is significantly associated with type 2 diabetes diagnosed using Hb A1 c levels,independent of other cardiometabolic parameters.

Physical-biogeochemical interactions and potential effects on phytoplankton and Ulva prolifera in the coastal waters off Qingdao(Yellow Sea, China)

In recent years, the spectacular massive green tide of Ulva prolifera has become a recurrent phenomenon appearing every summer in the coastal waters off Qingdao(Yellow Sea, China), attracting the attention of scientists and local government. Based on multidisciplinary data collected during summer and winter, this study focuses on the hydrological characteristics and regional biogeochemical processes in coastal waters off Qingdao.The results show that the boundary of the Yellow Sea Cold Water Mass(YSCWM) can reach the Qingdao coastal region in summer and is locally raised to the upper layers to form coastal upwelling beyond tidal mixing and favorable wind. The regional summer upwelling off the Qingdao coast effectively enriches the nutrient concentrations in the upper water column and thus promotes growth of phytoplankton but reduces the dissolved oxygen(DO) concentration and pH value in the bottom. The regional summer upwelling off Qingdao coast may facilitate the growth and regional blooming of the U. prolifera that migrate to this region with the southerly wind.Additionally, the effects of the front on the aggregation of U. prolifera may be significant. In winter, the Yellow Sea Warm Current(YSWC) extends and spreads along the offshore region off the Subei Shoal towards the Qingdao coastal sea. This tongue-shaped warm water meets the cold coastal water off Qingdao, which leads to the formation of a physical front. As a consequence, remarkable fronts of nutrient and chlorophyll a(Chl a) also form between the shoreward warm water and the cold coastal water. This study increases the understanding of the interactions between the regional physical, chemical, and biological processes off the Qingdao coast.

Estimation and Prediction of Typhoons and Wave Overtopping in Qingdao, China

This study aims to estimate and predict the impact of climate change on typhoons and wave overtopping during typhoon progresses in Qingdao, China. The SWAN wave model is used to simulate wave elements. The scale coefficients of wave overtopping are estimated using an empirical prediction formula. A total of 75 tropical cyclones affected Qingdao from 1949 to 2019. These tropical cyclones can be grouped into eight categories according to typhoon tracks. Typhoon wind speed during Track G is projected to decrease, and those of the other seven typhoon progresses will increase by 0.35% – 0.75% in 2025, 0.69% – 1.5% in 2035, and 1.38% – 3.0% in 2055. The significant wave height and wave overtopping outside the bay are greater than those inside the bay. Among the 506 typical points selected, the maximum values of the significant wave height and wave overtopping inside the bay are mainly distributed in the range of 0 – 2 m and 0 – 60 m^3 km^(-1) s^(-1), respectively. The increments of the significant wave height and wave overtopping of Track F are most obvious. The significant wave height of Track F will increase by 50.5% in 2025, 51.8% in 2035, and 53.4% in 2055. In the 2℃ scenario, the maximum value of wave overtopping of Track F will increase by 21.9% in 2025, 24.3% in 2035, and 29.5% in 2055. In the 4℃ scenario, the maximum value of wave overtopping of Track F will increase by 21.9% in 2025, 24.3% in 2035, and 29.5% in 2055.

A study on the supply relations of different groundwater in Qingdao subway line R3

In this paper, the correlation between different groundwater in the study area is analyzed by using the hydrological data from the hydrogeological test holes and the long-term observation holes based on the hydrogeological data between the Jinggangshan Road Station and the Jianianhua Station on the Qingdao Subway Line R3. The conclusions are as follows. When the drills are near the seashore(less than 50m) and the backfilled formation has a large permeability coefficient(the backfilled components being coarse particles), the Quaternary pore water is connected with the seawater and there is correlation between the two. When the drills are far from the seashore(more than 50m) or the backfilled formation has a small permeability coefficient, there is no correlation between the two. When the drills are near the seashore(less than 50 m) with developed bedrock fissure, the bedrock fissure water is connected with the seawater and there is correlation between the two. When the drills are far from the seashore(more than 50m), or when the bedrock fissure is undeveloped, there is no correlation between the two. There exists an aquifer(mainly marine muddy silt clay layers and partially silt clay layers) between the Quaternary pore water and the bedrock fissure water, which blocks the connectivity between the two. Consequently, there is no correlation.

Analysis on the Characteristics of Environmental Kuznets Curve and Assessment of Air Quality in Qingdao City

[Objective] The aim was to analyze the characteristics of environmental Kuznets curve (EKC) and assess air quality in Qingdao City. [Method] The EKC characteristics of Qingdao from 1996 to 2008 were studied based on air pollutant discharge indices, air pollution indices and economic data from the environmental quality reports and statistics yearbooks of Qingdao, and the air quality of Qingdao City was assessed. [Result] With the increase of GDP per capita, the total discharge of industrial waste gases improved remarkably, and its EKC showed inverted U type. Meanwhile, the discharge of SO2, industrial fumes and industrial dusts decreased on the whole, and the EKC of sulfur dioxide and industrial fumes was close to inverted N type. In addition, air pollution composite index also showed decrease trend, and its EKC showed inverted N type. In recent 13 years, the concentration of SO2, particles and NO2 in ambient air of Qingdao City showed decrease trend on the whole, especially particles. In addition, PM10 has replaced SO2 as the primary pollutant since 2001, and air pollution type has changed from coal smoke pollution to mixed mode pollution of coal smoke and motor vehicle. The mitigation of air pollution in Qingdao City could be attributed to the implementation of industrial waste gas management by the governments of Qingdao City. [Conclusion] The study could provide theoretical foundations for the establishment of environmental policies in Qingdao City.

Variation Characteristics of Mass Concentration of Inhalable Particles in Qingdao, China

The geographical condition of Qingdao, China is relatively special;the transport of various inland pollutants, the emissions of marine aerosol and local pollutants will have an impact on the changes of atmospheric aerosol concentration. By using the stability classification method, trajectory clustering analysis and the NOAA HYSPLIT model, the seasonal distribution characteristics of atmospheric inhalable particulate matter concentration in Qingdao, China and its relationship with meteorological conditions, mixed layer height, and the seasonal characteristics of Qingdao pollutant transport were analyzed. The results show that the variation trends of PM2.5 and PM10 were about the same, and there are obvious seasonal differences, which are high in winter and spring, and low in summer and autumn. The concentration of inhalable particulate matter has a negative correlation with temperature, wind speed and relative humidity. The concentration of inhalable particulate matter is distinct in different relative humidity ranges. When the wind speed is less than 3 - 4 m/s, there are more inhalable particles, while the mass concentration shows obvious reduction with the wind speed more than 4 m/s. There is a significant negative correlation between the mass concentration of pollutants and the daily maximum mixed layer height. The larger the concentration of pollutants, the smaller the thickness of the daily largest mixed layer. Conversely, the smaller the mass concentration of pollutants, the larger the thickness of the daily largest mixed layer. The pollutant transport in Qingdao has obvious seasonal characteristics. The air mass in spring, autumn and winter is mainly medium-long distance transport from Mongolia and southern Russia, and medium-short distance transport from Inner Mongolia and northeast of China. The source of air masses in summer is mainly transported from the eastern and sea areas.

THE FORMING-STORING ENVIRONMENT AND ABUNDANCE CONDITIONS OF QUATERNARY UNDERGROUND BRINE IN THE EMBAYED COAST OF QINGDAO

The discovery of useful brine resources in the embayed coastal zone of Qingdao is an important achievement in research on potential underground brine resources stored in Quatemary littoral facies in the North China coast. The Holocene transgression in this area provided the ancient seawater sources for forming brine. In spite of the unfarorable geological conditions (narrow littoral plain. shallow and thin Quatemary sedimentary strata) Qingdao’s embayed coast has deposition basins with bay-in-bay and weir dam ideal for gathering brine. The geologic structure of the littoral Quatemary deposition basin and hydrologic condition(deficient runoff) comprise favorable environment for the formation and abundance of underground brine.The embayed coast geomorphy controls the distribution of brine in patches that form small mineral zones in some parts. The brine aquifer whiment series formed under Quatemary littoral plain sedimentary and hydrogeologic environment are usually single phreatic ones. Part of the thick deposit areas consists of phreatic and poorly confined aquifers. Near the river mouth, there can someimes be brine aquifers interbeded with saline water ones. The basement of the brine ore deposits is comprised of Mesozoic rock formations. Underground brine is scattered almost all over the littoral plain and only in the larger plain’s area is the narrow saline water belt distributed beyond the brine zone. The structural features of the brine aquifer sediment series along the Jiaozhou Bay Coast are typical of those in the North China coast. We name it"Jiaozhou Bay Type" Its features are different from those of other brine aquifer sediment series such as "Laizhou Bay Type" and"Bohai Bay Type" in the littoral plain of the Bohai Sea.

Spatial Distribution Assessment and Source Apportionment of Land-Based Pollutant Yield from Qingdao, China

The spatial distribution of chemical oxygen demand(COD) and total nitrogen(TN) yield from Qingdao are studied by comparing pollutant yield amount, densities and spatial aggregation(Getis-Ord indexes) among the land-based pollutant source regions(PSRs) entering the three sub-seas(i.e. the Jiaozhou Bay(JZB), other coastal area in the Yellow Sea(OCAYS) and Laizhou Bay(LZB), respectively). Industrial composition of the loads are also studied by comparing pollutant yield among the sources of agriculture, rural domesticity, industry, urban domesticity and service, and calculation of Gini coefficient. Results show that spatial distribution of COD and TN yield from Qingdao are extremely unbalanced. The JZB, with less than 3% of the total coastal sea area of Qingdao, received 62% COD load and 65% TN yield from Qingdao, while the OCAYS, with more than 97% area, only received 23% COD and 20% TN, which consist with the much worsen water quality of JZB than that of OCAYS. On the other hand, the source apportionment of COD and TN loads in the PSRs entering JZB and the OCAYS was similar. The agricultural and domestic sources with high pollution intensity account for more than 80%, while the industrial and service sources with low pollution intensity account for less than 20%. While Gini coefficients, COD 0.81 and TN 0.84 which are much higher than the ‘imbalance' threshold of 0.4, show the uneven industrial structure of Qingdao. These results may be useful in the determination of land-based pollution total amount control at the PSR level.

On Time Word“Zan gan-er”(趱赶儿)in Qingdao Dialect

In Qingdao dialect,“zan gan-er”(趱赶儿),meaning“small amount of time”,always collocates with“duo(多),yi(一),bu(不),mei(没)”etc.,to form many types of quantifiers which hold the similar meaning“brief period”different in degree and which act as attributes,adverbial modifiers or objects.Due to the existence of a syntactic limitation of the“one core-verb”,in the serial-verb construction,the word“zan gan”(趱赶)gradually became an adverb,meaning“in a hurry”,and then under the analogy or derivation of the reasoning mechanism,the hidden meaning of its“temporary time”gradually became clear in daily life,and finally the word“zan gan-er”(趱赶儿)was evolved into a time word which meaning was“small amount of time”.
