A 1.8 kb HinfI fragment carrying the chitinase gene(chiA) from Serratia marcescens was isolated from the plasmid pLCHIA and was inserted into the SmaI site downstream of the strong Ptac promoter in the expression vector pKK223-3,yielding the plasmid pKChiA.The 2.1 kb PtacChiA fusion fragment was excised by BamHI from the plasmid pKChiA and was inserted into the single BamHI site present within the plasmid pMC71A,thus generating the plasmid pMChiA.High levels of chitinase were produced by the E.coli strains HB101 and JM105 carrying the plasmid pKChiA or the plasmid pMChiA,with the amount of production were higher 1～3 fold than that produced by the strains carrying the plasmid pLCHIA.

Objective:To explore the urgent management strategy for quadriplegia following China Wenchuan earthquake under filed condition.Methods:The 57-year-old male patient was sent to the earthquake relief team of Changzheng Hospital,Second Military Medical University.He was hit by heavy object during the Sichuan earthquake 6 days ago.Physical examination revealed cervical spinal cord injury accompanied by incomplete paralysis.The patient underwent cervical 3-7 laminectomy under general anesthesia.Results: After surgery,the muscle strength of lower limbs recovered to grade four from grade one;the muscle strength of upper limbs recovered to grade five from grade three.Sensory loss was found below the nipple level and totally recovered after operation.Conclusion:Early surgery for quadriplegia following earthquake trauma can timely relieve compression to the spinal cord and therefore improve prognosis of patients.Under field condition where facilities are not readily available,decompression of spinal cord can be achieved by lamineetomy via posterior approach.The key to successful operation is correct diagnosis and skillful manipulation.

OBJECTIVETo investigate the association between cervical curvature and cervical sympathetic symptoms.

METHODSThe clinical data of 318 patients with cervical spondylosis who underwent surgical treatment in our department between July 2003 and December 2007 were retrospectively analyzed. All patients were divided into group without sympathetic symptoms (n = 284) and group with sympathetic symptoms (n = 34) . The curvatures of both groups on cervical lateral radiographs were measured using Borden method and statistical analysis was performed.

RESULTSThe incidence of abnormal cervical curvature in group with cervical sympathetic symptoms were 67.6% (23/34), which was significantly higher than that in group without cervical sympathetic symptoms (50.7%, 144/284) (P < 0.05).

CONCLUSIONCervical curvature abnormality may be an independent factor that affects the cervical sympathetic symptoms.

Objective To preliminarily investigate the methods,safety and short to medium-term effectiveness of the interventional ultrasound applying in the hybrid procedure to treat the thrombosis of arteriovenous graft(AVG).Methods Twenty patients with the thrombosis of AVG,who received the hybrid procedure defined as Fogarty catheter thrombectomy and percutaneous transluminal angioplasty (PTA) guided by the ultrasonography,were retrospectively investigated. The display effects of the ultrasonography were observed.The technical and clinical success rates were evaluated.All the cases were followed up every 3 months for at least 1 year to evaluate the post-interventional assisted primary patency and the post-interventional secondary patency.Results All the processes were clearly displayed and well guided by the interventional ultrasound during the procedure.The technical and the clinical success rates were both 100%.No major complications were recorded.The post-intervention assisted primary patency rate was 100%,92.9%,85.7%,71 .4% at 3,6,9,12 months,respectively.The post-intervention secondary patency was 100%,100%,89.5%,89.5% at the correspondent months.Conclusions This pilot research shows the hybrid procedure guided by the interventional ultrasound to treat the thrombosis of AVG has high success rate and satisfied patency in short to medium-term.The interventional ultrasound is an effective, safe and convenient guiding method to the hybrid procedure,and has the value for clinical application.

Objective To study the iodine nutritional status of population living in Tibetan pastoral areas,in order to provide a scientific basis for prevention and control of iodine deficiency disorders.Methods Drinking water samples were collected to test iodine content in agricultural town(Kajiaman) and pastoral area(Zuogaiduoma town) of Hezuo in Gannan Tibetan autonomous prefecture.Thirty of child-bearing age,pregnant and breastfeeding women were selected,respectively,and 90 male adults aged 20-50 from these families(1 from each family) and 90 children aged 8-10 (30 people in each age group) from local schools were randomly sampled at the same time,and urinary iodine (UI) was measured randomly.Edible salt and main food samples were collected to test iodine content from the 10 families of the three types of women,respectively,and they were asked to recall its family intake of food species in the past 24 h excluding spices.The water iodine was determined using arseniccerium redox method (GB/T 5750.1-2006) ; UI with ammonium persulfate digestion-arsenic cerium catalytic spectrophotometric method (WS/T 107-2006) ; salt iodine used direct determination method(GB/T 13025.7-1999); and food iodine with alkali the gray arsenic cerium contact colorimetry.All these work were done in May,2011.Results The average of water iodine was (1.63 ± 0.14)μg/L in agricultural areas and (2.08 ±1.90)μg/Lin pastoral areas of the 10 water samples tested,respectively.The median urinary iodine(MUI) among women of pregnant,lactating and child-bearing age,male adults and children was 141.99,126.65,253.33,258.07,191.0μg/L,respectively,in agricultural areas and 137.26,97.36,126.16,159.48,285.07 μg/L,respectively,in pastoral areas.The difference of MUI in lactating,male adults and children between pastoral and agricultural areas was statistically significant.The proportion of UI ＜ 50 μg/L was less than 20％,and ＜ 100 μg/L was less than 50％ among all population except lactating woman and pregnant women in pastoral areas.The iodized salt coverage rate was 100％(30/30) in agricultural areas and 90％(27/30) in pastoral areas,and the salt iodine was (32.1 ± 7.8)mg/kg in agricultural areas and (32.3 ± 6.0)mg/kg in pastoral areas,respectively.The food structure in agricultural areas was mainly potato,naked oat fruit,cabbage and so on,the average dietary iodine content was 285.7 μg/kg,and in pastoral areas was mainly chow mein,wheat flour,ghee,yogurt,barley and so on,the average dietary iodine content was 51.1 μg/kg.Conclusions There is no iodine deficiency in general in the population in Tibetan areas with low water iodine.However,iodine nutrition of pregnant women can not be guaranteed.It is recommended that classified guidance measures be taken to ensure the sustainable elimination of iodine deficiency disorders in the Tibetan minority areas.

This study was performed to investigate the chemical constituents in the twigs and leaves of Harrisonia perforate. Six compounds were isolated from the 95% EtOH extract of the twigs and leaves of Harrisonia perforate by silica gel, ODS, Sephadex LH-20 column chromatographies and preparative HPLC. On the basis of chemical properties and spectra data, these compounds were identified as harriperfin E (1), kihadanin A (2), kihadanin B (3), 6α-acetoxyobacunol acetate (4), gardaubryone C (5), and β-sitosterol methyl ether (6), respectively. Compound 1 is a new chromone, and compounds 2-6 are isolated from this plant for the first time.
