Origin, Flow of Formation Water and Hydrocarbon Accumulation in the Zhenwu Area of the North Jiangsu Basin, China

In order to understand the origin and flow of formation water and to evaluate the hydrocarbon accumulation and preservation conditions, the properties of formation water chemistry and dynamics of the Zhenwu area in the southern Gaoyou Sag, North Jiangsu Basin, China, have been investigated. The results show that Xuzhuang oilfield is infiltrated discontinuously by meteoric water under gravity, which consequently leads to the desalination of formation water. Formation water in the Zhenwu and Caozhuang oilfields is less influenced by meteoric water infiltration, and the origin is interpreted to be connate water. Hydrocarbon migration, accumulation and preservation are closely related to the hydrodynamic field of formation water. Formation water concentrates gradually during the process of centrifugal flow released by mudstone compaction and the centripetal flow of meteoric water infiltration, leading to the high salinity of the central part. The geological conditions of the southern fault-terrace belt are poor for hydrocarbon accumulation and preservation as meteoric water infiltration, leaching and oxidation, while the central part, i.e., northern Zhenwu and Caozhuang oilfields is beneficial for an abundance of hydrocarbon accumulation. Most of the large scale oil-~as fields locate herein.

CIS-Based Mapping and Zonation of Landslide Hazards in Xiaojiang Valley of Southwestern China

Through the field survey, previous researches and interpretation of aerial photos, a landslide information database of Xiaojiang Valley, Yunnan Province was set up based on the remote sensing (RS) and geographic information system (GIS) technologies. In the paper, a quantitative model for the landslide hazard assessment and zoning was presented, in which the potential energy could be obtained on basis of thorough analysis of the potential sliding volume, distance and direction of the landslide body. Taking landslide potential energy as the index of the hazard severity zonation, the study area was divided into severe, heavy, medium and light hazard zones.

Effect of Sheng-jiang powder on multiple-organ inflammatory injury in acute pancreatitis in rats fed a high-fat diet

BACKGROUND Obesity worsens inflammatory organ injury in acute pancreatitis(AP), but there is no effective preventive strategy. Sheng-jiang powder(SJP) has been shown to alleviate multiple-organ inflammatory injury in rats with high-fat diet-induced obesity. Hence, SJP is supposed to have an effect on multiple-organ inflammatory injury in AP in rats fed a high-fat diet.AIM To explore how obesity may contribute to aggravating inflammatory organ injury in AP in rats and observe the effect of SJP on multiple-organ inflammatory injury in AP in rats fed a high-fat diet.METHODS Rats were randomly assigned to a control group(CG), an obese group(OG), and an SJP treatment group(SG), with eight rats per group. The rats in the OG and SG were fed a high-fat diet. From the third week, the rats in the SG were given oral doses of SJP(5 g/kg of body weight). After 12 wk, AP was induced in the three groups. Serum amylase level, body weight, Lee's index, serum biochemistry parameters, and serum inflammatory cytokine and tissue cytokine levels were assessed, and the tissue histopathological scores were evaluated and compared.RESULTS Compared with the CG, serum triglyceride, total cholesterol, interleukin-6, and interleukin-10 levels were significantly higher in the OG, and serum high-density lipoprotein cholesterol level was significantly lower in the OG. Moreover,enhanced oxidative damage was observed in the pancreas, heart, spleen, lung,intestine, liver, and kidney. Evidence of an imbalanced antioxidant defense system, especially in the pancreas, spleen, and intestine, was observed in the obese AP rats. Compared with the OG, serum high-density lipoprotein cholesterol, interleukin-10, and superoxide dismutase expression levels in the pancreas, spleen, and intestine were increased in the SG. Additionally, SJP intervention led to a decrease in the following parameters: body weight; Lee's index; serum triglyceride levels; serum total cholesterol levels; malondialdehyde expression levels in the pancreas, heart, spleen, lung, and liver; myeloperoxidase expression levels in the lung; and pathological scores in the liver.CONCLUSION Obesity may aggravate the inflammatory reaction and pathological multipleorgan injury in AP rats, and SJP may alleviate multiple-organ inflammatory injury in AP in rats fed a high-fat diet.

Sheng-jiang powder ameliorates obesity-induced pancreatic inflammatory injury via stimulating activation of the AMPK signalling pathway in rats

AIM To investigate the mechanisms by which Sheng-jiang powder(SJP) ameliorates obesity-induced pancreatic inflammatory injury.METHODS Sprague-Dawley rats were randomized into three groups: normal group(NG), obese group(HLG), or SJP treatment group(HSG). Obesity was induced by feeding a high-fat diet in the HLG and HSG, while the NG received standard chow. Rats were euthanized after 12 wk, and blood and pancreatic tissues were collected for histopathological analyses. Nuclear factor kappa-light-chain-enhancer of activated B cells(NF-κB) and transforming growth factor beta(TGF-β) expression, serum triglyceride and adiponectin levels, and apoptosis in pancreatic acinar cells were assessed. A high-fat AR42 J acinar cell injury model was established using very low-density lipoprotein(VLDL). AR42 J acinar cell culture supernatant, treated with different interventions, was applied to seven groups of pancreatic stellate cells(PSCs). The proliferation of PSCs and the expression of fibronectin and type I collagenase were assessed.RESULTS Compared with the NG, we found higher pathological scores for pancreatic tissues, lower serum adiponectin levels, higher expression levels of NF-κB in pancreatic tissues and TGF-β in pancreatic inflammatory cells, and increased apoptosis among pancreatic acinar cells for the HLG(P < 0.05). Compared with the HLG, we found reduced body weight, Lee's index scores, serum triglyceride levels, and pathological scores for pancreatic tissues; higher serum adiponectin levels; and lower expression levels of NF-κB, in pancreatic tissue and TGF-β in pancreatic inflammatory cells for the HSG(P < 0.05). The in vitro studies showed enhanced PSC activation and increased expression levels of fibronectin and type I collagenase after SJP treatment. An adenosine 5‘-monophosphate-activated protein kinase(AMPK) inhibitor inhibited PSC activation.CONCLUSION SJP may ameliorate obesity-induced pancreatic inflammatory injury in rats by regulating key molecules of the adiponectin-AMPK signalling pathway.

Denitrification in Qi'ao Island coastal zone,the Zhujiang Estuary in China

Samples of sediments and the overlying water were collected in the Qi＇ao Island coastal zone,the Zhujiang（Pearl River） Estuary（ZE）.Denitrification rates,sediment oxygen demand（SOD）,and fluxes of inorganic nitrogen compounds were investigated with N2 flux method,using a self-designed continuous flow through and auto-sampling system.The results indicate that the denitrification rates varied between 222 and 908 μmol/（m2·h） with an average of 499 μmol /（m2·h）.During incubation,the sediments absorbed dissolved oxygen in the overlying water with SOD ranging from 300 to 2 363 μmol/（m2·h）.The denitrification rates were highly correlated with the SOD（r2=0.77） regardless of the NO-3＋NO-2 concentrations in the overlying water,organic carbon contents in sediments and water temperature,suggesting that the SOD was probably the main environmental factor controlling the denitrification in the Qi＇ao Island coastal zone.There was a net flux of NO-3＋NO-2 into the sediments from the overlying water.The NH＋4 flux from sediments into water as the result of mineralization was between 12.3 and 210.3 μmol/（m2·h）,which seems limited by both organic carbon content in sediment and dissolved oxygen concentration in the overlying water.

Construction Strategies of Social Security System for Wan-jiang Urban Belt's Migrant Workers

Theoretical debate and practice exploration on social security of migrant workers were introduced.The political direction and security layer on social security for migrant workers in Wan-jiang urban belt were analyzed:the first layer is to implement wage payment guarantee and employment injury insurance;the second layer is to emphasize serious disease insurance and endowment insurance;the third layer is unemployed insurance and social assistance.The primary strategy of building a social security system for migrant workers in Wan-jiang urban belt was put up:wage payment guarantee system that is united in certain regions should be promoted;employment injury insurance system that is undertaken by enterprises should be built;a social health care system for serious diseases should be set up;multi-layers endowment insurance system for migrant workers should be created;vocational training and training in how to start a business should be built as well as the unemployment insurance system;social assistant system based on the basic cost of living allowances should be set up.

Delineating suspended sediment concentration patterns in surface waters of the Changjiang Estuary by remote sensing analysis

Three Landsat TM imageries （taken on 18 May 1987,4 August 1998 and 28 July 2007） were used as the data source to identify the spatial and temporal variations of the suspended sediment concentration （SSC） in surface waters of the Changjiang Estuary.Atmospheric correction was carried out to determine the water-leaving reflectance using the FLAASH module.A regression equation between surveyed SSC and suspended sediment index was chosen to retrieve the SSC from the Landsat TM images.In addition,tidal harmonic analysis was performed to calculate tidal conditions corresponding to the acquisition time of satellite images.The results show that the SSC spatial patterns are similar to the in situ observation results,which show the highest SSC in the region of turbidity maximum zone in the Changjiang Estuary.For the period of 1987 to 2007,the SSC pattern is controlled mainly by tidal dynamic conditions and wind speeds,rather than sediment discharges from the river.

Sheng Jiang San, traditional multi-herb formulation, exerts anti-influenza effects in vitro and in vivo via neuraminidaseinhibition and immune regulation

OBJECTIVE Sheng Jiang San(SJS),a multi-herb formulation,is used in treating high fever,thirsty and anxiety in ancient China and it is sometimes used to treat seasonal influenza in modern.However,there is no evidencebased investigation and mechanism research to support SJS′s anti-influenza efficacy.This study aims to investigate the anti-influenza effect of SJS and its possible mechanisms.METHODS In this study,we examined the inhibitory effect of SJS against different influenza viruses on Madin-Darby canine kidney cells.Influenza virus infected BALB/c mice were employed as in vivo model to evaluate the efficacy.Mice challenged with A/PR/8/34(H1N1)were orally administrated SJS 1 g·kg^-1 daily for seven days and monitored for 14 d.The survival rate,body mass changes,lung index,lung viral load,histopathologic changes and immune-regulation of the mice were measured.The underlying anti-influenza virus mechanisms were studied by a series of biological assays in vitro to determine if hemagglutinin,ribonucleoprotein complex or nerauminidase were targets of SJS.RESULTS SJS exerted a broad spectrum of inhibitory effects on multiple influenza strains in a dose-dependent manner.And IC50 of SJS against A/WSN/33(H1N1)was lower than 35 mg·L^-1.SJS also protected 50%of mice from influenza virus PR8 infection.The lung index and the lung viral load of SJS treated mice were signifi⁃cantly decrease compared with untreated mice.SJS 2 g·L^-1 inhibited 80%of neuraminidase enzymatic activity.SJS also up-regulated TNF-αand IFN-αand down-regulated IL-2 of influenza virus induced mice.CONCLUSION SJS is a useful formulation for treating influenza virus infection.
