Objective: To investigate the predictors of subjective well-being (SWB) in older adults. Methods: 236 old people in Beijing were assessed on 7 potential predictors chosen from 2 taxonomies of resources-internal vs. external and physical vs. psychological.Results: There was no relationship between age and SWB. Perceived social support, health status and general self-efficacy correlated significantly with subjective well-being(?=0.27,0.19,0.15); perceived social support, health status and general self-efficacy have direct impact on subjective well-being, perceived social support and health status have secondary impact on subjective well-being through the factor general self-efficacy as well.Conclusions:The external factors can influent the SWB both directly and indirectly.

Objective To investigate the therapeutic effect of VSD combined with external fixator in the treatment of open tibial and fibular fractures in Tibet plateau. Methods From August 2014 to August 2015, totally 16 cases of open tibial and fibular fractures were treated in our department, including 12 males and 4 females with an average 39. 4 years-old. There were 4 cases of proximal and mid tibial fractures while 12 cases were distal fractures. Debridement, vacuum sealing drainage combined with external fixator for stabilization of fractures was performed in all patients after general condition was improved. A vacuum sealing drainage change or second stage wound closure or soft tissue coverage was undergone after 7 days. Bone union time by X-ray and complications were recorded. Results All wounds were healed by second stage. Twelve patients months were followed up ( by calling back to the hospital ) for an average 18 months ( 12 to 24 months ) , 4 cases were lost to follow-up. X-ray demonstrated that bone union was obtained at a mean 5. 5th month (3 to 7 months). There were 9 cases (75%) obtained a first phase of fracture healing, while 3 cases ( 25%) of delayed healing. Pin-track infection was occurred in two patients and was cured by conservative treatment. No complications of deep infection, graft skin or flap necrosis, malunion, nonunion or osteomyelitis was seen during follow-up. Conclusions Vacuum sealing drainage combined with external fixator for treatment of open tibial and fibular fracture in Tibet can rapidly and effectively stabilize the fracture, and simultaneously safely and effectively seal the wound, reduce the wound healing time, promote fracture healing and lower the complication rates.

Metagenomic cosmid libraries containing 1.26 x 10(5) clones, covering about 4.8 x 10(6) kb metagenomic DNA of uncultured microorganisms from the contents of buffalo rumens were constructed, and 118 independent clones expressing beta-glucosidase activity were isolated from the libraries. Screening of these clones showed that eight clones expressed relatively higher beta-glucosidase activity at pH 5.0 and 37 degrees C. One out of the eight clones was subcloned. Sequencing analysis showed that an open reading frame (ORF) of 2223 bp, termed umcel3G, potentially encodes a beta-glucosidase. The encoded product shared highest homology with a beta-glucosidase from Bacillus sp. at 60% identity and 73% similarity. The umcel3G was over-expressed in Escherichia coli and the size of the translated product Umcel3G on SDS-PAGE was in agreement with the predicted molecular mass. Zymogram analysis showed that Umcel3G exhibited beta-glucosidase activity, confirming that this ORF encodes a beta-glucosidase. The Umcel3G, purified with Ni-NTA column, exhibited optimal activity at pH 6.0-6.5 and 45 degrees C. Certain ions such as Ca2+, Zn2+ had significant positive effect on the activity of Umcel3G. However, some ions such as Fe3+, Cu2+ gave significant inhibitory effect on the enzyme. The Ni-NTA purified recombinant beta-glucosidase Umcel3G had a specific activity of 22.8 IU/mg at pH4.5, 35 degrees C and at the presence of 5 mmol/L Ca2+, indicating that this enzyme has potential applications in the fermentative production of ethanol by simultaneous saccharification and cofermentation (SSCF) of lignocelluloses.

Sorghum (Sorghum bicolor L.) was one of the most important crops in the world next to wheat, rice, maize, soybean and barley. Using the callus derived from immature inflorescence as the recipients, we efficiently transformed sorghum varieties 115, ICS21B and 5-27 with the insecticidal Bacillus thuringiensis (Bt) cry1Ab gene carried in the T-DNA of binary vectors which contained hygromycin resistance gene and gus gene via Agrobacterium tumefaciens. After gradient selection with hygromycin, a total of 21 independent transgenic plant lines, 52 transgenic plants were regenerated, and the average stably transformation efficiency was 1.9%. The integration and transcription of cry1Ab gene in transgenic sorghum was confirmed by PCR analysis, Southern blotting and RT-PCR analysis. The Bt proteins were expressed in most transgenic plants with different level from plant to plant by Western blotting and ELISA assay. According to insect bioassay in laboratory, the transgenic plants with a relatively high level of Bt gene expression displayed insect-resistance to pink rice borer (Sesamina inferens).

It is the current confusion encountered by integrated Chinese and Western medicine that how to find the breakthrough direction of integrating Chinese and Western medicine, from crossover to integration to innovation, and open up a new horizon of integrated Chinese and Western medicine. The progress of Chinese medicine lay in expanding the scope of diagnosis and treatment with the help of modern diagnostic and therapeutic equipments and developing “micro” identification, while the progress of Western medicine lay in looking at “macro” and developing systemic medicine and integrated medicine, both of which are in the direction of each other. The “state-target identification and treatment” may become an important way to build a modern diagnosis and treatment system of integrated Chinese and Western medicine, and the thinking mode of “from target to state” is a further refinement and development on the basis of the theoretical system of “state-target identification and treatment”, which provided a clearer solution for the current stage of the integrated Chinese and Western medicine model, and pointed out the important development direction for the future integrated Chinese and Western medicine. From the perspective of strategic level and diagnosis and treatment practice, it integrated the “target-state” thinking mode into the modern diagnosis and treatment model of the integrated Chinese and Western medicine, i.e., “Western medicine as the basis and treating with Chinese medicine; Chinese medicine as the basis and treating with Western medicine”. On the one hand, Western medicine should strengthen the reference to the traditional theories and holism of Chinese medicine, and advocate a higher level of education on the integrated Chinese and Western medicine under the guidance of the traditional theories of Chinese medicine. On the other hand, the “from target to state” mode of thinking should be applied to guide the establishment of diagnostic and treatment strategies and clinical selection of medicines in clinical practice, so as to locate the target and adjust the body state in a gradual and orderly manner, and to provide practical methods for the modern clinical work of the integrated Chinese and Western medicines. Chinese and Western medicine systems can learn from each other, combine organically, give full play to their respective strengths, and form an internal law, so as to make breakthroughs and innovations in the integrated Chinese and Western medicine model.
