Next generation sequencing technologies,providing high speed and throughput that contribute greatly to DNA sequencing,have many applications in clinical virology,including identification of novel or unsuspected viruses,evaluation of human viromes,investigation of viral genetic diversity and evolution,monitoring of antiviral drug resistance,and analysis of virus-host interaction.Meanwhile,due to the complexity in bioinformatics data processing and lack of quality management standards,further efforts and explorations need to be put in the application and quality management of NGS in clinical laboratory.

A total of 587 keywords expressing the health information needs of diabetics were selected from diabetes-related 8762 questions covered in Yahoo Q and A, coded according to the cataloguing system and classification strategies of diabetes information, processed by text formatting, and clustered by multi-dimensional analysis, which showed that the most concerned health information in diabetics is the daily management, diagnosis and treatment of diabetes while rare attention is paid to its prevention.

Objective To investigate the relevance of liver function and neurobehavior of offspring of SD rats ex-posed to sodium valproate in the second trimester. Methods 30 SD rats at 12. 5 d of pregnance were randomly di-vided into three groups: low-dose group (300 mg/kg VPA was injected into abdominal cavity), high-dose group (600 mg/kg VPA);control group (normal saline). The offspring of low-dose groupe were grouped as VPA-low-dose;the offspring of high-dose groupe were grouped as VPA-high-dose; and the offspring of control group were grouped as control group. Then, we tested the liver and neurological function of each group of offspring, respective-ly, and analyzed their relevance. Results The levels of serum total protein and albumin of the high-dose group were considerably lower than these of the low-dose group which were significantly lower than these of control group ( P<0. 01 for both total protein and albumin);the levels of ALT, AST and blood ammonia of the high dose group were drastically higher than these of the low dose group, which were dramatically higher than these of control group ( P<0. 01 ) . The duration and of stereotyped movement disorder in experimental group was markedly longer than this of the control group, while this of the high-dose group was notably longer than this of the low-dose group ( P<0. 01 );the frequency of the stereotyped movement disorder of experimental group was significantly more than this of the control group, while this of high-dose group was obviously more than this of the control group (P<0. 01). In the Morris water maze, the escape latency of the high-dose group was remarkably longer than this of low-dose group, which was observably longer than this of control group (P<0. 01);the swimming distance of the high-dose group was tremendously shorter than this of low-dose group, which was considerably shorter than this of control group ( P<0. 05 , P<0. 01 ) . Correlation analysis of liver function and neural behavior showed that the neurobe-havioral abnormalities were negatively correlated with level of total protein and albumin, and were positively related with the level of blood ammonia, ALT and AST ( P<0. 01 ) . Conclusion The VPA exposure in the second tri-mester leads to the decrement of serum albumin and total protein and to the increment of AIL, AST and blood am-monia;and it also causes the neurobehavioral abnormalities of offspring. The reduction of synthesis of liver albumin and the rise of ALT, AST and blood ammonia can influence the neurobehavioral abnormalities. And there were both of the factors which result in the neurobehavioral abnormalities of offspring exposured to VPA in the second trimes-ter.

Referring to relative documents,it reviews the developments on the relation between IIS and gastro-intestinal hormones(gastrin,gallbladder bile-syst contractin,active vessel intestinal peptide and article P),and sums up the relativity study on the relativity between different TCM types of IIS and gastro-intestinal hormones secretion level.

As many naturally-derived proteins,keratins have intrinsic biological activity,good biocompatibility and are biodegradable.Human hair keratins,as one type of the autogenous proteins,also have low immune rejection.Compared to other autogenous materials,human hair keratins come from a variety of sources and show attraction in field of regenerative medicine.The human hair keratins applied in neural implant materials,wound dressing,cell culture substrates,drug delivery system and soft tissue reconstructions,which are based on hydrogels,scaffolds coating,films and composite materials present huge development potential in regenerative medicine.

Objective As part of the basic for cost-benefit assessment in decision for environmental protection measures, health benefit from improvement of air pollution was provided through this study. Methods According to the results from many well-done studies of local, domestic, and international authoritative institutions on relationship of air pollution and health impact, E-R functions (Exposure-Response) in terms of total mortality and morbidity of respiratory diseases from acute and chronic effects associated with increase of unit air pollutants (each 100 ?g/m3 TSP and 10 ?g/m3 SO2) were identified. As a real practice, the excess (avoidable) number of deaths and patients of respiratory diseases associated with 100 ?g/m3 TSP and 10 ?g/m3 SO2 of air pollution were estimated for Fushun City in year of 2000. The costs of medical treatment, as well as the payment for labor days were investigated. The direct and indirect economic losses from corresponding diseases were calculated. As for the estimation of economic loss from excess deaths, three methods of evaluation were applied, i.e. labor capital method; value of statistics life (VOSL), namely the method of willing to pay (WTP); and value of life year (VOLY). Results The total economic benefit combined from above aspects resulting from decreasing 100 ?g/m3 TSP ranges over 1.4 hundred millions-3.4 hundred millions yuan, accounting for 0.75%-1.95% of total product value (GDP) of Fushun City in year of 2000. Methods and indices of monetary estimation for health impact of air pollution adapted to Liaoning city was suggested. As the author's point of view, the third method of VOLY was preferable, by which, 1.48 hundred millions yuan benefit was estimated, accounting for 0.85% of GDP. Conclusions Domestic E-R functions should be worked out for assessing economic loss due to environmental pullution.

Objective To study the optimum culture media and liquid conditions in shaking flasks for laccase production by Ganoderma lucidum. Methods Taking S_3 stain of G. lucidum as test materials and laccase activity of G. lucidum as measurement index to optimize the culture media and liquid conditions through orthogonal test. Results The optimum culture components of media were: Glucose 30 g/L, cotton 0.2%, (NH_4)_2HPO_4 0.66 g/L, casein 0.5%, Tween-80 0.15 mL; the optimum conditions were: initial pH value of medium was 5.5, 75 mL medium was in 250 mL-flask, inoculation was 12.5%, mycelium age was 5?24 h for 9?24 h culture. Conclusion Laccase activity of G. lucidum has been improved remarkably in the optimum culture media and liquid conditions.
