The method of ratio coefficient of amino acid, based on the theory of amino acid balance, is a new one designed to evaluate nutritional value of food protein. The calculation and the meaning of Ratio Coefficient (RC) and Score of RC (SRC) are described. RC can be used to judge limit amino acid and to calculate the amount that shall be added to a fortified food. SRC can be used to evaluate nutritional quality of protein. A high correlation was obtained between SRC and Biological Value (BV), P

Objective To investigate the effect of salvia Miltiorrhiza on the patients with chronic allograft nephropathy.Method 20 cases were treated by the combination of salvia miltiorrhiza and routine anti-rejection therapy.Results The effect of the combination in salvia group was better than that in the control group .The significant difference was found between the two groups of the patients (P

ObjectiveTo compare the early rehabilitation of child with brain impair syndrome and cerebral palsy executed in hospital and in family.Methods180 children of 0～2 years old with brain impair syndrome and cerebral palsy were divided into group A and group B randomly. The children of 0～6 months old were in group A1 and group B1, while that of 6 months～2 years old were in group A2 and group B2, correspondingly. Children in group A accepted early formal strengthen rehabilitation training in hospital, and that in group B accept family rehabilitation through guidance. Development quotient (DQ) were assess with Japan Yuanchengsi infant analysis growth scale half a year after.ResultsThe DQ of group A showed higher than that of group B(P<0.01), and DQ of group A1 was higher than DQ of group A2(P<0.05).ConclusionEarly rehabilitation training in hospital is more effective on early cerebral palsy.

Neovascular age-related macular degeneration(nAMD)and polypoidal choroidal vasculopathy (PCV)are leading causes of blindness and visual impairment in older population.They are both with a hemorrhagic and exudative macular disorder.PCV has been proposed to be a sub-type of nAMD,hut this is a matter of controversy.Although several genes are found to be associated with PCV and nAMD(CFH,ARMS2/HTRA1),but more genes show no common association with the two diseases.such as BF/C2,Elastin,PEDF,SERPlNG1,VEGF,APOE genes.All these Results might imply that PCV and nAMD have different pathogenesis.But in the current state of our knowledge for PCV and nAMD.we still could not conclude if they are the same diseases.The purpose of these review is to discuss the recent progress in the molecular biology of PCV and nAMD.

Objective To identify the correlative and risk factors of non-oxygenation factors associated with postoperative prolonged mechanical ventilation (PMV) of aortic dissection(AD).Methods AD patients undergoing surgery during January 2010 and January 2015 were enrolled.Prolonged mechanical ventilation was defined that duration of ventilation more than 48 h.Results There were 240 patients,average age was (50 ± 12)years.The correlative factors with postoperative PMV were:pre-opervative white blood cell (WBC) (r =0.241,P =0.003),emergency operation (r =0.263,P =0.004),Debakey type (r =-0.379,P =0.000),duration of operation (r =0.329,P =0.000),postoperative diastolic pressure (r =-0.205,P =0.007),heart rate (r =0.246,P =0.001),postoperative hemoglobin (r =-0.213,P =0.005),calcium(r =-0.262,P =0.001),glucose (r =0.274,P =0.000),lactate(r =0.272,P =0.000) and pericardial effusion (r =0.239,P =0.032).Logistic analysis indicated that:the duration of operation,WBC and postoperative blood calcium were:2.063,1.285,0.016,respectivly(all P ＜ 0.05).Conclusions The correlative factors were:preoperative WBC,emergency operation,Debakey Type,duration of operation,heart rate,postoperative diastolic pressure,hemoglobin,calcium,glucose,lactate,and pericardial effusion.Duration of operation,WBC and postoperative blood calcium were risk factors predicting PMV.

Objective To evaluate the effect of initial empirical antibiotherapy in CAP since the practice of the clinical path -way and the classification management of antibiotic and the analysis of sputum culture .Methods One hundred and sixty patients with CAP consistent with the clinical pathway were divided according to the preferred choice of empiric antibiotherapy , the results of disea-ses distribution, objective, number, therapeutic effect, drug distribution and sputum culture were listed .Results The most preferred antibiotic of initial empiric antibiotherapy were penicillins with a β-lactamase inhibitor, bibasic cephalosporin and respiratory fluoro -quinolone, it was identical with the recommendation of guideline and indirectly demonstrated that the pathogen of CAP was identical with the guideline.Conclusions The initial therapy of CAP is still depended on empirical antibiotherapy , the most CAP are cured by correct empirical antibiotharepy according to the guideline , the instruction effect of the pathogen detection of sputum to the therapy of CAP is limited.

Objective To detect the relationship between XPD Lys751Gln polymorphism and the risk of adult acute leukemia (AL). Methods 100 adult AL patients and 100 controls were chose as case and Lys751Gln were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) analysis in peripheral blood. Results The genotype frequency of Lys/Lys, Lys/Gln, Gln/Gln were 83 %, 16 %, 1% in case group and 90 %, 10 %, 0 in control group, respectively. The difference the two groups was no signficant difference (x2=1.44, P =0.49). No significantly increased risk for adult AL was observed for those carrying variant genotype with OR analysis (x2 = 2.10, P =0.15, OR =1.84; 95 % CI 0.80-4.25). Individuals with the variant genotype of XPD Lys751Gln might enhance the risk of adult AL (OR =2.77, 95 % CI 0.99-7.73). Conclusion XPD Lys751Gln polymorphism is found to have relationship with adult acute lymphocytic leukemia.

Objective:To study the effect of sulforaphane(SFN) on the growth of human bladder cancer cell and its mechanism in vitro. Method:Morphological characteristics of T24 cell nucleus induced by SFN were observed by AO/EB fluorescein staining .The effect of SFN on the T24 cell cycle was determined by flow cytometry. The expression of TrxR at the transcriptional and translational levels were measured by RT-PCR and Western blot methods respectively. Results:(1) After the cells were treated with 10 ?mol/L and 20 ?mol/L SFN for 24 h and 48 h, nuclear fragmentation and apoptotic body were seen under fluorescence microscope. (2) SFN could block the cell cycle at the G0/G1 phase showed by flow cytometry. Moreover, the treatment of 20 ?mol/L SFN for 48h could cause the appearance of sub-G1 before G0/G1 phase. (3) The expression of TrxR mRNA were increased by the treatment of 10 ?mol/L SFN for 4 h, 10 h,24 h ,compared with the control group. Furthermore ,the treatment with high dose SFN (20 ?mol/L ) for 10h or 24 h could induce the expression of TrxR mRNA more significantly . (4)The expression of TrxR protein in the 10 ?mol/L SFN for 24 h group was augmented compared with the control group , and aftertreatment with 20 ?mol/L SFN for 8 h and 24 h, its expression was significantly higher than that in the control group . Conclusion:SFN can inhibit the growth of T24 cell ,induce apoptosis and arrest T24 cell in G0/G1 phase. Its mechanism is associated with the induction of TrxR both at the transcriptional and translational levels.

[Objective]To measure the verus inclination of the proximal tibial of young Chinese through radiographs and determine how many degrees should the femoral prothesis be externally rotationed during total knee arthroplasty(TKA).[Method]Standardized anteroposterior radiographs of the entire lower legs of 200 volunteers' were taken. Two angles were measured as followes:Angle PT: angle between tibial articular margins and a line perpendicular to the tibial mechanical axis;Angle FT:angle between the transcondylar tangent anda line perpendicular to the tibial mechanical axis. [Result]Angle PT has a mean value of 4.06? and Angle FT is 5.00?. [Conclusion]When the posterior condylar axis is used during TKA for Chinese, the femoral prothesis should be externally rotationed 5.00? to get the optimum rotational orientation.
