OBJECTIVETo investigate surgical outcomes of strip nail internal fixation with bone graft in treating tibial plateau fracture.

METHODSFrom May 2012 to May 2014,36 patients with tibial plateau fracture were retrospectively analyzed, including 25 males and 11 females with an average age of 43.5 (ranged from 17 to 65) years old. The time from injury to operation ranged from 3 to 10 days with an average of 5.8 days. All patients were treated with L-shaped and T-shaped strip nail internal fixation with bone graft. It was evaluated by the Knee Functional therapy assessment method of the Special Surgical Hospital of American at final following-up. Varus angle, caster angle and femorotibial angle were recorded and compared at 3 days and 1 year.

RESULTSOperative time was (2.2 ± 0.6) h on average, blood loss was (310.5 ± 36.2) ml on average, hospital stay was (14.8 ± 2.7) days on average. Thirty-six patients were followed up from 12 to 30 months with an average of 18.2 months. Fracture healing time ranged from 4 to 8 months with an average of 6.2 months. The difference is not significant among varus angle, caster angle and femorotibial angle at 3 days and 1 year. According to the knee functional therapy assessment method of the Specialized Surgical Hospital of American, 18 cases got excellent results, 13 good, 4 moderate and 1 poor.

CONCLUSIONStrip nail internal fixation with bone graft for the treatment of tibial plateau fracture could effectively prevent the joint surface from secondary collapse, and achieve anatomic reduction, stable fixation and earlier functional exercise in further to get satisfied clinical effects.

The average life expectancy in Macau is ranking the second in the world, the consumption of fresh medicinal plants is a profound culture in Macau. The paper focus on the distribution of the antioxidant herbs, a comprehensive investigation and analysis the amount of the plant resources was carried out. The antioxidant activity of alcohol extracts was determined by using the DPPH method, and six kinds fresh herbs with high antioxidant free radical activity were screened out. Reference to adult daily dose of vitamin C, it is calculated that the daily dose amount of fresh herbs is less than 200 g. For the expected shortage of resources and the ecological status of Macau, we give some suggestions of herbal introduction in population ecology reconstruction.

The hom gene encoding for homoserine dehydrogenase was amplified from the genomic DNA of Corynebacterium glutamicum ATCC 13032.After the kanamycin-resistant gene(Km)cassette from plasmid pET28a was inserted into the center of hom,the hom::Km cassette was then electroporated into the competent cell of C.glutamicum ATCC 13032.And kanamycin-resistant clones were obtained.PCR was performed to confirm whether the Km gene was integrated into the hom gene of these clones and the recombinant strains of hom-disrupted were screened out.Fermentation results showed that the lysine yield of the hom-disrupted strain C.g-hom::Km-8 reached 4.7 g/L,which was 6.7 times that of C.glutamicum ATCC 13032.

Cucumber mosaic virus was detected from infected Basella rubra L. with the indirect enzyme-linked immunosorbent assay. Total RNA was extracted from infected leaves and the cDNAs of coat protein gene of CMV-Ba were obtained by RT-PCR. The amplified cDNA fragments were then cloned into pMD 18-T vector and sequenced,the result showed that the CP gene was 657 nucleotides in length. This sequence was aligned with the obtained CP gene and some CMV strains or isolates of subgroup Ⅰ and subgroup Ⅱ in GenBank using DNA MAN software. The results showed that CMV-Ba shared 90.9%~93.8% and 76.1%~76.9% identity with the known CP genes of subgroup Ⅰ and Ⅱ respectively in nucleotide level,on the other hand,amino acids deduced from CMV-Ba CP gene shared 92.7%~97.7% and 72.4%~78.1% identity with the known CP protein of subgroup Ⅰ and Ⅱ,respectively. This suggested that CMV-Ba CP gene belongs to CMV subgroupⅠ.

Nicotiana tabacum is an important and classical model plant which can respond to the change of environmental conditions by accumulating osmoprotectants, such as glycerol and proline which contribute to the re-establishment of homeostasis when exposed to various adverse environmental stresses, such as drought, salinity, high and low temperatures. The optimization of ultrasonic extraction (UE) conditions of glycerol-3-phosphate dehydrogenase (GPDH) of tobacco leaf have been built by orthogonal test. It showed that optimum of the powers, treatment times, slot times and leaf-to-solvent ratios of UE was 75w, 2h, 2s, and 1[DK]∶12 g/ml, respectively. Under these conditions, the activity of GPDH has been tested as 0.3937U/mg protein, which was higher than other extraction methods such as liquid nitrogen and grinding on ice bath. According to investigation, it is the first description of determination of content of GPDH with ultrasonic in tobacco. It could provide basis for the further research in the relation of content of glycerol and osmotic pressure in tobacco.
