ObjectiveTo evaluate the feasibility of detecting the mutations of KRAS,EGFR in nonsmall-cell lung cancer and colorectal cancer patients with high resolution melting curve analysis. MethodsAt first,the mutations in KRAS exon 2 and EGFR exons 18 to 21 of 5 patients with non-small cell lung cancer and 5 patients with colorectal cancer were detected by high resolution melting curve analysis.Then the results were confirmed with direct sequencing. ResultsBy high resolution melting curve analysis,1 of 10 patients was found to carry EGFR 19 mutation who was harboring 2236-2250del mutation.By direct sequencing,consistent results of the patients with mutations orwithout mutations were got. Conclusion s The new high resolution melting curve analysis was more efficient,more convenient than direct sequencing.Moreover,it was a low-cost test,which was suitable for clinic test.

Objective To investigate the clinical effects of bioglue compound and anatomic plate in treatment of tibial plateau fractures. Methods 28 cases of tibial plateau fractures were treated by means of open reduction and internal fixation with bioglue compound and anatomic plate. The intervals between operation and injury ranged from 5 to 10 days. The amounts of bioglue compound implanted ranged from 3 to 8 grams. Results All the patients were followed up for 6 to 22 months. All the fractures healed satisfactorily without sunken joint surface. According to Mechant criteria, the result was excellent in 13 cases, good in 11 cases, moderate in 3 cases and poor in 1 case. The total excellent and good rate was 85.3 %. Conclusion Internal fixation with bioglue compound and anatomic plate can result in good effects in treatment of tibial plateau fractures, because the bioglue compound possesses high bone inductive potentialities to repair bone defects.

Objective The rational medication route of puerarin was explore d by studying the concentration- time curve and by comparing the histological and organic distribution difference of puerarin administered by intravenous injecti on or gastric gavage in mice, so as to supply a referential data for its rationa l application. Methods The NIH mice were used as experimental subject. The pu erarin concentrations in the plasma, tissue and organs at different time points were determined by HPLC. The PK solutions 2.0 program, a noncompartmental model software, was applied to calculate the pharmacokinetic parameters of puerarin an d to construct its plasma concentration- time curve. Results (1)The pharmacok inetic parameters of puerarin in mice were shown that the T1/2E of puerarin susp ension (0.2 mg? g- 1) by oral administration is 38.061min, CL =991.534 mL? mi n- 1, Cmax =3.6? g? mL- 1, Tmax =30 min, and AUC(0- ∞ ) =201.7? g? min? mL- 1, the bioavailability of puerarin suspension is 3.77 % compared to i.v puerarin injection. (2) Administered by intravenous injection (i.v), the puerari n distributed in the liver, kidney, plasma, spleen, muscle, lung, uterus and tes ticle rapidly, and the concentration of puerarin was the highest in the liver an d kidney and lower in the heart and brain. Distribution of puerarin suspension b y oral administration is similar to puerarin injection by i.v. However, the conc entration of puerarin in the tissues and organs by oral administration was lower than by i.v; the liver/heart, liver/brain, kidney/heart and kidney/brain concen tration ratios of puerarin by gavage administration were lower than those by i.v . Conclusion The bioavailability of puerarin by oral administration was poor, but the histological distribution characteristics of puerarin shows that the tox ic and side effects of puerarin are lesser by oral use than by intravenous injec tion.

Liver ferritin of Sphyrna zygaena(SZLF) with purity of mass spectrum was prepared in batch. Under) the condition of acidifying medium at pH 1.0, PAGE showed that SZLF subunits treated for 20 min began) to dissociate. A whole process of subunit dissociation and recombination was monitored by transmission electron microscopy(TEM). In addition, the changes of size of both protein shell and iron core were also determined) by TEM directly. It was found that in the acid dissociation process of SZLF subunits, the size of iron) core and protein shell showed the same trend of change, which might be related to not only the iron release) of inner iron core but the dissociation and unfolding of the protein shell. The passway of SZLF recombination is a fast step, which is a conversion process from incompact moltenglobule to compact ferritin. Under the assistant of matrix acidity pH 3.0 and laser, SZLF mixed with horse spleen ferritin(HSF) still has capacity to release) its subunits to form subunit ions for mass analysis by a MALDI-TOF mass spectrometer, which indicates that the interaction intensity between the subunits was weaken but they were not unfolded under this pH condition. TEM technology can be applied in studying both dissociation and recombination in ferritin subunits.

Objective To analyze the characteristics and changes in the disease spectrum of Air Force(AF) servicemen in order to provide reference for the determinatron of the overall level of health of AF and priorities of disease prevention and control.Methods The data of outpatient and inpatient diseases between 2009 and 2013 in AF was collected and analyzed statistically according to the International Classification of Diseases-9(ICD-9),and statistical description was performed with SPSS18.0.Results Between 2009 and 2013,unit B had the highest number of outpatients and inpatients,accounting for 47.74% and 39.64% respectively.The upper respiratory tract infections,gastroenteritis/gastritis,chronic low back pain,skin diseases,nasal sinusitis,training injury,trauma,hemorrhoids,varicocele and stone diseases were the common and frequently occurring diseases in AF,which were the top ten in the disease spectrum.Among them,the incidence and admission rate of skin diseases kept declining.However,the incidence of gastroenteritis/gastritis in unit A,the incidence and admission rate of chronic low back pain in unit B and D,the incidence of injury in unit D,as well as the incidence of neurological headache and hypertension in unit C and D were higher than in other units.Conclusion Respiratory system disease,and occupation-related diseases such as low back pain,training injuries,trauma,skin disease and digestive system disease are the focus of health care in AF.Health education and health promotion for these diseases should be improved,and health intervention for key populations should be enhanced.

Objective To evaluate the effect of isoflurane preconditioning on cell apoptosis during renal ischemia-reperfusion (I/R) in rats.Methods Thirty male Sprague-Dawley rats, aged 12-14 weeks, weighing 300-320 g, were randomly divided into 3 groups (n =10 each) using a random number table: sham operation group (group S);I/R group;isoflurane preconditioning plus I/R group (group Iso+I/R).The rats were anesthetized with intraperitoneal pentobarbital sodium 30 mg/kg.To establish the model of renal I/R injury, the right kidney was removed, and the left renal pedicle was occluded for 30 min with atraumatic mini-clamp for 30 min, followed by 2 h reperfusion.In Iso+I/R group, 1.5％ isoflurane was inhaled for 1 h, followed by 30 min of washout before I/R.In S and I/R groups only oxygen 2 L/min was inhaled for 1 h.Arterial blood samples were taken at 2 h of reperfusion to determine the concentrations of serum creatinine (Cr), blood urea nitrogen (BUN) and cystatin C (CysC).The animals were then sacrificed, and left kidneys were sampled for determination of the cell apoptosis (by TUNEL), expression of p53, Bax and Bcl-2 mRNA (using real-time fluorescent quantitative PCR), and expression of Bax, Bcl-2, and caspase-3 (by Western blot analysis).The Bcl-2/Bax ratio was calculated.Results Compared with group S, the serum Cr, BUN, and CysC concentrations were significantly increased, the Bcl-2/Bax ratio was decreased, Bcl-2 mRNA, Bax mRNA, Bcl-2, Bax and caspase-3 expression was up-regulated, and AI was increased in group I/R.Compared with group I/R, the serum Cr, BUN, and CysC concentrations were significantly decreased, the Bcl-2/Bax ratio was increased, Bcl-2 mRNA, Bax mRNA, Bax and caspase-3 expression was down-regulated, and AI was decreased in group Iso+I/R.There was no significant difference in p53 mRNA expression among the three groups.Conclusion Regulating the balance between Bcl-2 and Bax and inhibiting apoptosis in kidney cells are involved in the mechanism by which isoflurane preconditioning reduces renal I/R injury in rats.
