Sustainability of Intensively Exploited Aquifer Systems in the North China Plain: Insights from Multiple Environmental Tracers

Environmental tracers are proving to be a unique tool for assessing groundwater sustainability, such as characterization of recharge, identification of pathways and sources of contaminants, and prediction of groundwater change in response to excessive abstraction. This paper helps to better understand the groundwater sustainability in the Quaternary aquifer from the tracer data in the North China Plain. Relatively modern ground waters occur in the piedmont plain with 3H-3He age less than 40 a within a depth 100 m. These ground waters are mainly recharged from the local precipitation and irrigation return. The recharge rate estimated by tracers is in the range of 0.24 to 0.32 m/a. Paleowater which is dated from 10 000 a B.P. to more than 35 000 a B.P. by radiocarbon dating is found in highly-confined portions of Quaternary aquifer systems. This indicates that water recharge took place during the past glacial period. The tracers have suggested a slow natural replenishment rates to the central plain. The aquifer has been overexploited currently. Some strategies that can be implemented to promote a sustainable groundwater supply are needed to implement in future.
Evolution of Groundwater Major Components in the Hebei Plain: Evidences from 30-Year Monitoring Data

Groundwater is the main water source in the Hebei Plain. Evolution of groundwater chemistry can not only provide scientific data for sustainable usage of groundwater resources, but also help us in better understanding hydrogeochemical processes in aquifers. Spatial distribution and temporal evolution were analyzed on basis of monitoring data between 1975 and 2005. Results showed that major components in groundwater had increasing trends since 1970s. Major components in shallow groundwater increased more than those in deep one. In shallow groundwater of piedmont alluvial fan-recharge zone, concentrations of Na+, Ca~(2+),SO_4~(2-)had great increasing trends, while other major components increased by less than 30%. There were great increasing trends in Na+, CI-, SO_4~(2-) concentrations in deep groundwater of central alluvial plain-intermediate zone, while other major components increased by no more than 20%. Deep groundwater from coast plain-discharge zone and piedmont alluvial fan-recharge zone showed no significant variations in major ion concentrations. In shallow groundwater, dissolution, evaporation and human activities played a major role in the increase in major components. However, groundwater mixture resulting from deep groundwater exploitation was believed to be the major factors for the increases in major components in deep groundwater of central alluvial plain-intermediate zone.
Boron Isotopic Fractionation and Trace Element Incorporation in Various Species of Modern Corals in Sanya Bay,South China Sea

The boron isotope paleo-pH proxy has been extensively studied due to its potential for understanding past climate change, and further calibrations were considered for accurate applications of the proxy because of significant variability related to biocarbonate microstructure. In this work, we studied the boron isotopic fractionation between modern marine corals and their coexisting seawater collected along shallow area in Sanya Bay, South China Sea. The apparent partition coefficient of boron (KD) ranged from 0.83╳10~(-3) to 1.69╳10~(-3), which are in good agreement with previous studies. As the analyzed coral skeleton (~5 g) spanned the growth time period of 1-2 years, we discussed the boron isotopic fractionation between pristine corals and modern seawater using the annual mean seawater pH of 8.12 in this sea area. Without taking the vital effect into account, (11B/10B)coral values of all living corals spread over the curves of (11B/10B)borate vs. (11B/10B)sw with the a4-3 values ranging from 0.974 to 0.982. After calibrating the biological effect on the calcifying fluid pH, the field-based calcification on calcifying fluid pH (i.e., A(pHbiol-pHsw)) for coral species of Acropora, Pavona, Pocillopora, Faviidae, and others including Proites are 0.42, 0.33, 0.36, 0.19, respectively, and it is necessary to be validated by coral cul-turing experiment in the future. Correlations in B/Ca vs. Sr/Ca and B/Ca vs. pHbiol approve temperature and calcifying fluid pH influence on skeletal B/Ca. Fundamental understanding of the thermodynamic basis of the boron isotopes in marine carbonates and seawater will strengthen the confidence in the use of paleo-pH proxy as a powerful tool to monitor atmospheric CO2 variations in the past.

Effects of loadingeunloading and wettingedrying cycles on geomechanical behaviors of mudrocks in the Colombian Andes

The mudrocks in the Colombian Andes, particularly those exhibiting low cementation (bonding), are susceptible to degradation when the environmental conditions change, which are challenging issues for engineering works. In this paper, the changes in physico-mechanical properties of mudrocks were monitored in laboratory, and some influential factors on the mechanical competence of geomaterials were studied. The geotechnical characteristics and experimental designs were developed from physical, chemical, mechanical and compositional points of view. In the tests, the techniques such as vapor equilibrium technique (VET) were employed to apply wettingedrying cycles and to control relative humidity (suctioncontrolled) and loadingeunloading cycles through ultrasonic wave velocities technique. The results show that the main failure mechanisms for the laminated mudrocks start on the microscopic scale by fissures coalescence, exhibiting physico-chemical degradation as well; the global geomechanical behavior presents a state between a ductile, like rock, and a fragile, like soil. The obtained results can provide engineering values according to monitoring laboratory set, when compared with in situ conditions.
Latest progress of soft rock mechanics and engineering in China

The progress of soft rock mechanics and associated technology in China is basically accompanied by the development of mining engineering and the increasing disasters of large rock deformation during construction of underground engineering. In this regard, Chinese scholars proposed various concepts and classification methods for soft rocks in terms of engineering practices. The large deformation mechanism of engineering soft rocks is to be understood through numerous experiments; and thus a coupled support theory for soft rock roadways is established, followed by the development of a new support material, i.e. the constant resistance and large deformation bolt/anchor with negative Poisson’s ratio effect, and associated control technology. Field results show that large deformation problems related to numbers of engineering cases can be well addressed with this new technology, an effective way for similar soft rock deformation control.
Homeodomain leucine-zipper proteins and their role in synchronizing growth and development with the environment

The Arabidopsis (Arabidopsis thaliana L.) genome encodes for four distinct classes of homeodomain leucinezipper (HD-ZIP) transcription factors (HD-ZIPI to HD-ZIPIV), which are all organized in multi-gene families. HD-ZIP transcription factors act as sequence-specific DNA-binding proteins that are able to control the expression level of target genes. While HD-ZIPI and HD-ZIPII proteins are mainly associated with environmental responses, HD-ZIPIII and HDZIPIV are primarily known to act as patterning factors. Recent studies have challenged this view. It appears that several of the different HD-ZIP families interact genetically to align both morphogenesis and environmental responses, most likely by modulating phytohormone-signaling networks.

唑来膦酸预防老年乳腺癌患者阿那曲唑所致骨质疏松的疗效

近年来,随着社会经济的发展以及人口的老龄化,肿瘤的发病率逐年上升,其中乳腺癌已跃居女性肿瘤死亡原因的首位,严重威胁了女性的健康,但随着科学的发展,虽然乳腺癌的发病率呈不断上升的趋势,而死亡率却有所下降,这主要得益于早期主诊断及有效的综合治疗,其中对于雌激素受体(ER)/孕激素受体(PR)阳性的绝经后乳腺癌患者,第3代内分泌治疗药物(AI)可明显改善乳腺癌患者预后,提高生存期。然而对于老年患者,由于生理性骨量丢失,故长期应用第3代AI势必进一步加重骨量丢失,增加关节痛、骨质疏松和骨折的发生率。第3代双磷酸盐-唑来膦酸与内分泌药物联合应用不但具有协同抗肿瘤效应,同时还可以显著治疗内分泌治疗药物引起的骨量丢失。本文观察了48例老年乳腺癌患者,在接受阿那曲唑治疗中同期应用唑来膦酸预防骨质疏松,现将结果报道如下。

Therapeutic effect of electroacupuncture, massage, and blocking therapy on external humeral epicondylitis

OBJECTIVE: To compare two therapeutic methods: electroacupuncture + massage + blocking therapy, and blocking therapy alone in the treatment of external humeral epicondylitis. METHODS: Eighty-six patients were randomized into two groups with 43 in each. The treatment group received electroacupuncture + massage + blocking therapy, while the control group received blocking therapy only. A course of electroacupuncture treatment included therapy once a day for 10 days. There were 10 treatments in a massage course and massage was given once a day, with a 1 -week interval given before the next course. A course of blocking treatment included therapy once a week, for two total treatments, and generally no more than three times. The therapeutic effects were evaluated with the visual analog scale (VAS), grip strength index (GSI) score, and Mayo elbow performance score (MEPS) before treatment and at 0, 6, 12, and 24 months after treatment to observe the total effective rate. RESULTS: In the treatment and control groups before treatment and at 0, 6, 12, and 24 months after treatment, the VAS scores were: 6.5 ±1.9 and 6.4 ± 1.6; 4.6± 1.3 and 4.6± 1.7; 4.8± 1.3 and 4.8± 1.2; 4.6± 1.2 and 6.6±1.6; and 6.5 ±1.6 and 6.5 ±1.3, respectively. The GSI scores were 63 ±8 and 63 ±8; 84 ±6 and 82±7; 82±7 and 82±6; 84±6 and 62±8; and 64± 6 and 64±7, respectively. The MEPS of both groups were 65±7 and 66±8; 85±6 and 84±7; 84±5 and 84± 7; 80±7 and 66±6; and 65±6 and 65±7, respectively. The total effective rates of the treatment and control groups at 0, 6, 12, and 24 months after treatment were 87.5% and 85.0% ; 85.0% and 82.5% ; 80.0% and 12.5%; and 2.5% and 5.0%, respectively. Compared with the treatment group, the control group had greater joint function, better therapeutic effect, and lower pain intensity (P<0.01), indicating a high recurrence rate in the 12th month after treatment. There were no differences in VAS, GSI, or MEPS at 0, 6, and 24 months after treatment (P> 0.05) between the two groups. CONCLUSION: We found that both methods were effective for external humeral epicondylitis. After 6 months of treatment, the effects were good in both groups. However, in the 12th month, the control group had a relatively severe relapse. After 24 months, both groups relapsed. The effect of electroacupuncture, massage, and blocking therapy used in combination lasted longer, delaying the recurrence of the disease.
Effect of Roucongrong (Herba Cistanches Deserticolae) on reproductive toxicity in mice induced by glycoside of Leigongteng (Radix et Rhizoma Tripterygii)

OBJECTIVE: The purpose of this research is to study the effect of Roucongrong (Herba Cistanches Deserticolae) on reproductive toxicity in mice induced by a glycoside extracted from Leigongteng (Radix et Rhizoma Tripterygii) (GRT). METHODS: Forty-eight BALB/c mice were randomly divided into two groups in the ratio of 1:3, 12 in one group and 36 in the other. The 12-mouse group was the control group that was intragastrically administered physiological saline for 3 weeks. The 36 mice in the other group were given 30 mg ?kg ~(-1) ? d ~(-1) GRT for 3 weeks, then randomly divided into 3 subgroups: the model group, GRT group and Roucongrong (Herba Cistanches Deserticolae) group, with 12 mice in each group. In the model group, 0.25 mL physiological saline was intragastrically administered; in the GRT group, GRT, 0.25 mL at 30 mg ? kg ~(-1) ? d ~(-1) was intragastrically administered once a day; in the Roucongrong (Herba Cistanches Deserticolae) group, mice were administered Roucongrong (Herba Cistanches Deserticolae) decoction equivalent to 0.25 mL at a final dose of 10 g ? kg ~(-1) ? d ~(-1) crude drug (calculated as per 20 times of 0.5 g ? kg ~(-1) ? d ~(-1) for adults), and GRT 0.25 mL at 30 mg ? kg ~(-1) ? d ~(-1) daily. After another 3 weeks of exposure, expression levels of the reproduction-related genes DEAD (Asp-Glu-Ala-Asp) box polypeptide 3, Y-linked, B-cell CLL/lymphoma 6 and Signal transducer and activator of transcription 3 were evaluated. RESULTS: After 6 weeks of GRT treatment, the spermatogenic cell population in the convoluted tubule of testis was in disorder and the tubule cavity expanded. Sertoli cell and Leydig cells exhibited atrophy or disappeared. The number of sperm decreased. The spermatogenic cell level of testis for male mice was ranked in order and sperm was produced in the cavity of the spermatogenic cell. The expression levels of DDX3Y, BCL6 and STAT3 were up-regulated. CONCLUSION: GRT affected reproduction-related genes. Roucongrong (Herba Cistanches Deserticolae) reversed reproductive toxicity in mice induced by GRT.

先天性风吹手一例

讨论先天性风吹手(windblown hand)是一种先天性掌指关节屈曲畸形,伴有掌指关节及手指向尺侧偏斜,部分患者可有手掌增宽,大鱼际肥厚,有的学者称此畸形为先天性掌挛缩征。根据既往资料及术中所见,其畸形和功能障碍与解剖学、形态学和运动医学相关联。从解剖学上看,在腱帽周围有数条异常分布的小肌肉,特别是在掌指关节腱帽远端的小肌肉群在静态肌张力或收缩时,可造成掌指关节屈曲,或持续“被动”屈曲。另外,这些异常分布的小肌肉群破坏了伸肌腱帽的正常解剖结构的平衡,加之异常分布的小肌肉群以尺侧居多,使伸肌腱帽向尺侧滑脱,手指尺偏。这些异常解剖结构可能是造成屈曲尺偏畸形的早期直接原因。从形态学上看,由于解剖结构的异常,掌指关节和手指长期处于屈曲和尺偏位,致使腱帽长期尺侧滑脱而不能复位,掌指关节尺侧关节囊挛缩,桡侧关节囊松弛,久之屈肌腱短缩,从而限制了掌指关节和手指的正常活动,畸形形态固定。这可能是后期的功能障碍和畸形加重并固定的继发原因。从运动医学上看,此畸形为先天性,手指的正常活动从出生即被限制,手部骨骼、肌肉、肌腱和关节等得不到正常生理运动的刺激,从而影响了手的正常发育,致使部分患者出现掌骨短粗、放射样排列、手掌增宽、大鱼际肥厚等畸形。这可能是导致患手发育异常的原因。手术方案依据致畸机制,切除异常小肌肉,去除致畸动力。松解和紧缩关节囊,延长指屈肌腱,以恢复解剖结构平衡,配合术后早期固定、中后期物理治疗及适当功能锻炼,有效地恢复了手的外形和功能。远期疗效需进一步随访。

支链甘油四醚膜类脂化合物在油气地表化探中的应用初探—以济阳坳陷油气田为例

来源于细菌的支链甘油四醚膜类脂化合物(brGDGTs),首先发现于泥炭中,是一种分布广泛、易于检测的重要生物标志化合物.研究了brGDGTs在济阳坳陷垛石桥地区150 cm深度土壤中的分布,结果在各样品中均检测到了brGDGTs化合物,总体含量为4.0~73.0 ng g~(-1),显示brGDGTs在空白对比区含量较低,而在油气藏区和夏口断层处含量明显升高. brGDGTs含量与油气田区分布以及酸解烃指标(乙烷含量)都具有良好的对应关系,表明研究区油气藏上覆土壤中brGDGTs含量同下伏油气藏油气的渗漏密切相关;并且相比于酸解烃等传统化探指标, brGDGTs化合物稳定性更强,可以记录历史时期烃类渗漏,因此brGDGTs可能发展成为一类重要的油气地表化探指标.

Nitric Oxide Is Required for Homeostasis of Oxygen and Reactive Oxygen Species in Barley Roots under Aerobic Conditions

Oxygen, the terminal electron acceptor for mitochondrial electron transport, is vital for plants because of its role in the production of ATP by oxidative phosphorylation. While photosynthetic oxygen production contributes to the oxygen supply in leaves, reducing the risk of oxygen limitation of mitochondrial metabolism under most conditions, root tissues often suffer oxygen deprivation during normal development due to the lack of an endogenous supply and isolation from atmospheric oxygen. Since changes in oxygen concentration have multiple effects on metabolism and energy production(Geigenberger, 2003), tight control of oxygen consumption and homeostasis is likely to be particularly important in underground tissues such as roots.
