The effect of addition nucleotides on heparinase production by Flavobacterium heparinum was reseached. The result indicated that addition of nucleotides cause different effects on heparinase production depend on its addi ng mode, single kind of nucleotide would restrain, but multiplex promote. The s trongest promotion happened when the propotion of nucleotides was consistent wit h the nucleic acids of heparinase mRNA. HPLC result confined the entrance of nu cleoides to the bactera cell. And it also suggested the synthesis metabolic of nucleic acids in F.heparinum was imbalance, there always be higher lever of purin nucleoides. L-Asp was added to medium culture to enhance pyridine nucle oides thynesis in order to improve the enzyme production ,which has been affecte d by the imbalance of nucleoides.

Objective To confirm the association between the“Tip-Apex Distance (TAD)”and cut-out of the lag screw from the femoral head.and to analyze other factors leading to the cut-out.Methods The complete radiographic and clinical data of 106 patients with femoral intertrochanteric fractures were available for this study. They were 65 men and 41 women,with an average age of 52.4 years (range,20 to 83 years).According to Evans classification.19 cases belonged to typeⅡ.25 to typeⅢ,32 to typeⅣ,29 to typeⅤ,and one to type R.The bone quality was classified by Singh rating system:44 cases were rated as typeⅥ.34 as typeⅤ,23 as typeⅣand five as typeⅢ.They were treated with open reduction and fixation with 135?dynamic hip screw (DHS).According to the finding of Baumgaertner that“TAD”beyond 25 mm would grcatly increase the risk of cut-out,the patients could be divided into two groups:59 cases with“TAD”less than 25 mm and 47 greater than 25 mm.Results The mean duration of follow-ups was 14.45 months (range,4.5 to 28.0 months).Of the 15 cases whose“TAD”was more than 30 mm,one had the cut-out.Of the seven cases whose“TAD”was more than 40 mm,two had the cut-out (P=0.000). The average age of the three patients was 78.7 years (range:75 to 83 years) and 27.1 years older than that of the 103 patients whose fracture healed (P=0.000).They belonged to the unstable intertrochanteric fracture of the femur (two to Evans type V and one to type R).The reduction was assessed as excellent in 43 cases,good in 47 cases,fair in nine cases (of whom one had the cut-out),poor in seven cases (of whom two had the cut-out). Conclusions The cut-out of the lag screw from the femoral head can be caused by age,fracture type and stability of reduction and“TAD”.The greater the“TAD”value,the greater possibility of cut-out.

Objective To determine the dietary nutritional status of rural residents in Midwestern Shandong Province,in order to improve the dietary pattern and health status of them.Method 11 987 residents,from 10 273 households,were included in this study by multi-stage randomized cluster sampling in 8 counties located in Midwestern Shandong Province.Questionnaire of Food Frequency (QFF) was applied to collect the information about the amount and frequency of food consumed by the subjects in the past year.Results The average intake of cereal,vegetable,fruit,meat,egg,milk,bean,oil and salt per reference man per day was 553.9 g,310.6 g,58.2 g, 36.3 g,50.1 g,16.7 g,34.4 g,44.8 g and 12.3 g,respectively.The average intake of energy,carbohydrate,protein,fat and dietary fiber per reference man per day was 12 095.6 kJ,451.8 g,85.6 g,78.8 g and 18.7 g as well Cereal food provides 66.1% of total energy; however,the meat provides only 6.6% of that.Carbohydrate,protein and fat amount to around 63.2%,12.0% and 24.8% of total energy, respectively.24.0% of fat intake was from animal food,while 76% of that was from vegetable food.Conclusions The intake of energy, protein,fat was sufficient for these subjects;however,the intake of vegetable,fruit,bean and meat was lower than the dietary reference intake.Moreover,oil and salt intake in these subjects was much higher than Chinese Recommended Nutrient Intakes.Thus,the amelioration of dietary pattern in rural residents will be an important task for nutrition workers in rural area of Midwestern part of Shandong Province in the future.

ObjectiveTo evaluate temporary balloon occlusion of the abdominal aorta in high-order position sacral tumor surgical operation as a useful adjuvant technique.MethodsReviewed 79 cases of patients from 2005 to 2015 treated in our department and the diagnosis of high-order position sacral tumor. Temporary balloon occlusion of abdominal aorta was used in 50 patients(male 29,female 21)during the sacral tumors surgical operations. The other 29 patients(male 18,female 11)with sacral tumors who received the non-temporary balloon occlusion therapy were used as control group. The statistical differences of the whole surgery time,the blood loss during the surgery,the happening of the postoperative deep vein thrombosis,the time of the postoperative extubation were analyzed. ResultsThe differences were statistically significant(P<0.001)in the whole surgery time of balloon occlusion group(146.36±29.38)min vs non-balloon occlusion group(206.03±125.93)min,the blood loss of balloon occlusion group(1610.70±491.14)ml vs non-balloon occlusion group(2658.62±562.213)mL, and the time of the postoperative extubation of balloon occlusion group(6.60±2.76)d vs non-balloon occlusion group(12.52±2.86)d. However,there was not significant difference of the happening of the postoperative deep vein thrombosis between balloon occlusion group and non- balloon occlusion group. ConclusionTemporary balloon occlusion of abdominal aorta is effective and reliable. It significantly reduced the time of operations,the loss of blood,mean days in hospital,effusion of post-operation and recurrence rate. It makes the operation of sacral tumors much more safer than before and is a technique worthy of popularizing.

Background The main cause of X linked juvenile retinoschisis is mutation of RS1 gene.The phenotype of X linked juvenile retinoschisis is associated with the mutation types of RS1 gene.However,the relationship of genotype and phenotype of X linked juvenile retinoschisis is unclear.Objective The present study was to survey the clinical phenotype of X-linked juvenile retinoschisis in twelve Chinese families with eleven different mutations in the XLRS1 gene. Methods Complete ophthalmic examinations with slit lamp biomicroscopy,fundus examination and Dhotography were carried out in 28 affected males.Ganzfeld electroretinography (ERG),fundus fluorescein angiography,A and B-scan standardized echography and optical coherence tomography(OCT)were also performed in some patients.The coding regions of the XLRS1 gene that encodes retinoschisin were amplified by polymerase chain reaction(PCR)and analyzed by the single strand conformation polymorphism(SSCP)assay.The RS1 gene mutations were determined by direct sequencing in an automated sequencer.Written informed consent wasobtained prior to the survey. Results The 28 affected males showed a typical foveal schisis with or without peripheral retinoschisis.The typical response to white single flash ERG was seen with a reduction of the b-wave amplitude and a relative preservation of the a-wave amplitude.causing a reduced b/a ratio in the male patients.A total of eleven different XLRS1 mutations in 12 families were identified,four of these mutations,including one frameshift mutaion(22 del T)of exon 1,Asp145His,Arg156Gly and Trp163X mutations of exon 5,were first described in this survey.One non-disease-related polymorphism(NSP),or the 576C to T(Pro192Pro)change of exon 6 was also newly reported herein.In the families with a frameshift(22 del T)mutation of exon 1,a splice donor site mutation(IVS1+2T

Objective This study was performed to assess the clinical feasibility of video-assisted mediastinoscopic lymphadenectomy in the treatment of resectable lung cancer.Methods Between March 2011 and May 2012,we retrospectively analyzed the data from 56 patients who underwent video-assisted mediastinoscopic lymphadenectomy(VAMLA).In patients receiving tumour resection subsequently,radicality of the previous mediastinoscopic dissection was controlled during thoracotomy.Results Mean operative time of video-assisted mediastinoscopic lymphadenectomy was(42.0 ± 13.5) min(range of 26-86 min).Mean number of resected lymph nodes was 12.4 ± 6.7 (range of 5-24).In video-assisted mediastinoscopic lymphadenectomy,the rates of lymph node dissection of stations 2,4,5,7,8 were 54.5％,92.7％,58.2％,100％,61.8％,respectively,there was no operative mortality and morbility.90.9％ patients achieved radical dissection.Conclusion Video-assisted mediastinoscopic lymphadenectomy is a clinically feasible procedure and provides more accurate staging of mediastinal node in lung cancer patients.It also plays an important role in minimal invasive surgery and neoadjuvant therapy.

Objective To study prevalence of metabolic syndrome (MS) , it's components and hyperuricemia (HUA) among Kazakh people in Xinjiang Uighur autonomous region, China. Methods A cross-sectional survey was conducted among Kazakh people aged 35 years and over in seven prefectures of Xinjiang, including Urumqi, Kelamayi (Karamay) , Fukang, Tulufan (Turpan), Hetian (Hotan) , Aletai (Altay) and Yili during October 2007 to March 2010, with a four-stage cluster sampling, the total sample size were 4094. Through the methods of questionnaire survey, physical examination, biochemical examination and so on, to study prevalence of MS in HUA and it's components by blood biochemical examinations. Results A total of 3915 Kazakh adult people, equal number of men and women, were surveyed, with a response rate of 95. 63 percent. Overall prevalence of HUA was 3. 96 percent( 155/3915 ) , 6.02 percent for men and 2. 03 percent for women(114/1894 and 41/2021) , respectively, with statistically significant difference ( P ＜ 0.05 ). Prevalence of MS was 39.47 percent in those with HUA and 22. 53 percent in those without HUA (45/114 and 401/1780), respectively (P ＜ 0.01). Among women, prevalence of MS was 46. 34 percent in those with HUA and 16. 11 percent in those without HUA( 19/41 and 319/1980), respectively (P＜0. 01). Prevalence of high blood pressure, hypertriglyceridemia, lower blood high-density lipoprotein cholesterol (HDL-C) and central obesity were 59.65 percent, 42.11 percent,32.46 percent, 7. 89 percent and 79. 82 percent in those with HUA, respectively, with prevalence of hyperglyceridemia and central obesity significantly higher than in those of non-HUA ( P ＜ 0. 05 ). Among women, prevalence high blood pressure, hypertriglyceridemia, lower blood HDL-C and central obesity were 48.78 percent, 39.02 percent, 41.46 percent, 2.44 percent and 78.05 percent, respectively, in HUA group, with prevalence of hyperglyceridemia, lower blood HDL-cholesterol and central obesity significantly higher than in those of non-HUA ( P ＜ 0. 05 ). Conclusions Prevalence of MS was higher in Kazakh people suffered with HUA than those without HUA, as well as prevalence of components of MS, suggesting that prevention and treatment for HUA is necessary, which can reduce MS and its components in the region.
