By using the methods of hydrocarbon generation kinetics and carbon isotope kinetics, combined with geological background of natural gas pool formation, the generation and accumulation of natural gas from Yinan 2 gas pool was studied in Kuqa Depression of the Tarim Basin. Natural gas of Yinan 2 gas pool is mainly derived from Middle and Lower Jurassic coal-bearing source rocks, and generally belongs to long time-accumulated gas. It is suggested that Yinan 2 gas is chiefly accumulated in the last 5 Ma, its Ro ranges from 1.25% to 1.95%, and the loss rate of natural gas is about 25%-30%. This work not only complements and reduces the deficiency of formation model of natural gas pools which traditionally depends on the matching relationships between source rock, reservoir, cap rock, and trap, but also is a useful reference in the study of other gas pools.

Technological advances in glaucoma have challenged the traditional treatment paradigm. Historically incisional surgery has been used in cases of advanced disease and/or uncontrolled intraocular pressures resistant to medical or laser interventions. More recently, perhaps due to advancements in imaging, surgery has been suggested to be beneficial earlier in the treatment paradigm. Despite these trends, surgical manipulation of the tissues and unpredictability of wound healing continue to result in surgical failure. Magnesium is an essential element for human body and plays a critically important role in maintaining the functional and structural integrity of several tissues, including the eye. Due to several of its advantageous properties such as non-toxicity, biodegradability, and high biological compatibility, magnesium alloy has attracted great attention as a novel biomaterial. Biodegradable cardiovascular stents made of magnesium alloy have already been introduced into clinical practice. The purpose of this review is to determine if bioabsorbable magnesium alloys can be utilized as a promising candidate for the development of a new generation of glaucoma surgical assistive devices.

The asialoglycoprotein （ASGP） receptor is a wellcharacterized hepatic receptor that is recycled via the common cellular process of receptor-mediated endocytosis （RME）. The RME process plays an integral part in the proper trafficking and routing of receptors and ligands in the healthy cell. Thus, the missorting or altered transport of proteins during RME is thought to play a role in several diseases associated with hepatocyte and liver dysfunction. Previously, we examined in detail alterations that occur in hepatocellular RME and associated receptor functions as a result of one particular liver injury, alcoholic liver disease （ALD）. The studies revealed profound ethanol- mediated impairments to the ASGP receptor and the RME process, indicating the importance of this receptor and the maintenance of proper endocytic events in normal tissue. To further clarify these observations, studies were performed utilizing knockout mice （lacking a functional ASGP receptor） to which were administered several liver toxicants. In addition to alcohol, we examined the effects following administration of anti- Fas （CD95） antibody, carbon tetrachloride （CCh） and lipopolysaccharide （LPS）/galactosamine. The results of these studies demonstrated that the knockout mice sustained enhanced liver injury in response to all of the treatments, as shown by increased indices of liver damage, such as enhancement of serum enzyme levels, histopathological scores, as well as hepatocellular death. Overall, the work completed to date suggests a possible link between hepatic receptors and liver injury. In particular, adequate function and content of the ASGP receptor may provide protection against various toxinmediated liver diseases.

Purpose: The aim of the present study was to evaluate the characteris tics of spasticity-related pain(SRP) and the correlation between SRP and gross motor capability in children and adolescents with cerebral palsy. Methods:137 caregivers/parents and 120 children/adolescents with cere bral palsy(age 2-17 years)who have upper limbs and/or lower limbs SRP were recruited from three Chinese study sites. The SRP was assessed b y the Questionnaire on Pain caused by Spasticity(QPS), including a s elf-report version, an interview-version for the children/adolescent and a proxy-report version for the parent(s)/caregivers. All the chil dren and adolescents were measured for gross motor functions by G ross Motor Function Classification System-Expanded & Revised(GMFCS E&R) and Gross Motor Function Measure-66( GMFM-66), Spearman’s rank correlation coefficients was used to determine the correlation betwe en QPS scores and GMFCS E&R and GMFM-66. Results: The greatest amount of SRP was found when the child was rece iving "physical therapy or stretching exercises". QPS scores have p ositive correction with the gross motor function as assessed by the G MFCS E&R in child interviewed group(lower limb r=0.533,p<0.001;upper limb r=0.644,p<0.013). QPS scores in child interviewer-administered group are in several cases associated with gross motor function as me asured by the GMFM-66. Conclusions: The SRP in children and adolescents with cerebral palsy tended to correlate with gross motor function. More methods and measu res are needed to manage and treat the SRP in children and adolescent s.

吲哚美辛(Indomethacin)广泛地应用于治疗风湿性关节炎,关节僵硬性脊椎炎,骨关节炎及急性痛风样关节炎。但在较高血药浓度时会产生与胃肠道、中枢神经系统有关的副作用,其应用受到严重限制。本研究是通过将吲哚美辛与PEG6000制备成固体分散体,然后和聚丙烯酸树脂压制成骨架片,以便一方面减少其副作用,另一方面达到预期的释药模式,从而发挥其优良的治疗作用。吲哚美辛在水中不溶,并具有多晶型,会严重改变其释药特征,而固体分散体恰能克服这些缺点。聚丙烯酸树脂型骨架片的孔隙率及曲率能控制其释药。
