Objective To study the early diagnostic value of olfactory function measurement to Alzheimer disease (AD). Method Detected the thresholds of detectability, identification threshold with pictu.re-based odor identification test in 21 AD patients (AD group) and 21 healthy elderly people (control group), and evaluated the relationship with mini-mental state examination (MMSE). Results AD group was impaired on threshglds of detectability [(1.81±0.75) scores], identification threshold [(2.48±0.68) scores]compared with control group [(1.24±0.89) scores and (2.00±0.71) scores, P< 0.05]. The thres holds of detectability and identification threshold were related to MMSE in AD group (r =-0.50,-0.54, P< 0.01). Conclusion The early diagnostic value of olfactory function measurement to AD is very great.

The brown slime inside pipeline of the polluted mineral waters well was analyzed. It was confirmed that the brown slime was a biofilm formed mainly by growth of bacteria contaminant, using microscope analysis. After treated with HCl, the brown crystals and mycelioid matter presented in slimes disappeared. It was verified these were metal deposits. The samples produced Prussia blue deposits by dropping K 4Fe(CN) 6 and HCl, which proved that the metal deposits were iron compound. Also it was believed the biofilm was produced by growth of iron bacteria, mixed with deposits of iron compound. The iron bacteria have been isolated from the slimes and cultured in the laboratory. The colony on agar plate also produced Prussia blue deposits after treated with K 4Fe(CN) 6 and HCl. The cells form of pure culture was the same as that in the samples by electronmicroscope analysis. Therefore, It indicated that the bacteria on biofilm inside pipeline were iron bacteria mainly.

OBJECTIVETo discuss the clinical effects of external fixator combined with limited internal fixation in the treatment of pediatric distal femur fractures.
METHODSFrom January 2008 to June 2014, 17 children of distal femur fractures were treated by external fixator combined with limited internal fixation. There were 12 males and 5 females, aged from 6 to 13 years old with an average of 10.2 years, ranged in the course of disease from 1 h to 2 d. Preoperative diagnoses were confirmed by X-ray films in all children. There were 11 patients with supracondylar fracture , and 6 patients with intercondylar comminuted fracture. According to AO/ASIF classification, 9 fractures were type A1, 5 cases were type A2,and 3 cases were type C1. The intraoperative and postoperative complications, postoperative radiological examination, lower limbs length and motion of knee joints were observed. Knee joint function was assessed by KSS score.
RESULTSAll the patients were followed up from 6 to 38 months with an average of 24.4 months. No nerve or blood vessel injury was found. One case complicated with the external fixation loosening, 2 cases with the infection of pin hole and 3 cases with the leg length discrepancy. Knee joint mobility and length measurement (compared with the contralateral), the average limited inflexion was 10 degrees (0 degrees to 20 degrees), the average limited straight was 4 degrees (0 degrees to 10), the average varus or valgus angle was 3 degrees (0 degrees to 5 degrees). KSS of the injured side was (96.4 +/- 5.0) points at final follow-up, 16 cases got excellent results and 1 good. All fractures obtained healing and no epiphyseal closed early was found.
CONCLUSIONExternal fixator combined with limited internal fixation has advantages of simple operation, reliable fixation, early functional exercise in treating pediatric distal femurs fractures.

Objective To establish a method of SYBR Green Ⅰ FQ-PCR for detecting the expression of miR-202 in peripheral blood mononuclear cells ( PBMC ) and analyze the expression of miR-202 and its clinical significance in MM.Methods Reverse transcription was performed with specific stemloop primer for miR-202,and then FQ-PCR was used to detected the expression of miR-202 in 21 MM patients and 20 healthy people.Data was presented as mean ± standard deviation ( (x) ± s ).Non-parametric Mann-Whitney test was used to analyze the difference between MM group and control group.In addition,1∶ 125 dilution of one test sample was detected by repeated 5 times,and the same sample was tested one time a day for 3 days,repeated 5 each time.The assessment of repeatability of measurements was done by calculating standard deviation and variation coefficient from threshold cycle (Ct).Results FQ-PCR detection of miR-202 in PBMC was amplified by the standard S-curve,with a single melting curve peak and no complex peak,which showed good specificity.The assay showed good reproducibility (intra-assay coefficient 1.2% and inter-assay coefficient 3.2% ) and high sensitivity ( 12.8 pmol/μ1).The expression of miR-202 in MM was 0.014 ( 0.007 - 0.221 ) and 1.844 ( 0.162 - 3.966 ) in normal controls.The expression level of miR-202 was significantly higher in MM than in normal controls (U =48.000,P <0.01 ).Conclusions FQ-PCR provide us a rapid,sensitive and specific method for detection of miR-202.The expression level of miR-202 is higher in MM than in normal controls.It is possible to play a role in MM progress and may be a useful marker to evaluate the development and treatment of MM.

The purpose of this paper is to clarify the structure-activity relationship of anti-tumor activity of diosgenin derivatives in vitro. Study has found that diosgenin can inhibit the reproduction of tumor cells by inducing apoptosis and the main target spot of this effect is Bcl-2. Based on the characteristics of pharmacophoric points' of the three-dimensional pharmacophore for Bcl-2 inhibitors, we have docked lots of diosgenin derivatives with Bcl-2, then synthesized 31 compounds of them, finally assessed the anti-tumor activity of the diosgenin derivatives in vitro against A375, A549, HepG-2 and K562. Preliminary studies of SAR have indicated that the aliphatic esters, and aromatic esters of diosgenin without F ring have no anti-tumor activity in vitro. The triazole bromides of diosgenin all achieve fairly good anti-tumor activity in vitro, and those with larger hydrophobic group have the better activity. The stronger is the hydrogen bonding interaction and dipole-dipole interaction of the heterocyclic of diosgenin and diosgenin without F ring and the acid ester of diosgenin without F ring, the better is the activity of derivatives.

AIM:To investigate the expression of extracellular matrix metalloproteinase inducer(EMMPRIN)and hepatocyte growth factor(HGF)in non-small-cell lung carcinoma(NSCLC)and their relationship with lymphoid metastasis and prognosis.METHODS:Expression of EMMPRIN and HGF in 77 cases of patients with NSCLC was detected immunohistochemically.The relationship of expression of EMMPRIN and HGF with tumor size,smoking,histological type,differentiation,lymphoid metastasis,clinical stage,and prognosis was analyzed.RESULTS:The expressive rates of EMMPRIN and HGF were 68% and 44%,respectively.The expressions of EMMPRIN and HGF were associated positively with lymphoid metastasis(r=0.371 and 0.339,P0.05).The expression of EMMPRIN was associated with the expression of HGF in NSCLC.CONCLUSION:The expression of EMMPRIN and HGF is associated with lymphoid metastasis and prognosis in NSCLC.Overexpression of EMMPRIN and HGF implies infavourable prognosis in NSCLC.

OBJECTIVETo explore the protective effect of modified danshou decoction (MDD) on teratogenicity of bisphenol A intoxicated pregnant rats.
METHODSForty-four successfully mated rats were randomly divided into 4 groups, 10 in the blank group and 10 in the model group, 12 in the MDD group and 12 in the positive control group. Bisphenol A (BPA) at the dose of 600 mg/kg was given to rats by gastrogavage in the latter three groups from the 1st day of mating to the 20th day, while the soybean oil was given to rats by gastrogavage in the blank group. No intervention was given to rats in the model group, but the normal saline, MDD condensed decoction, and shoutai pill (STP) condensed decoction was respectively given to rats in the rest three groups during the experimental period. All rats were sacrificed by the 20th pregnancy day.
RESULTSCompared with the model group, the body weight of pregnant rats and fetal rats, body length and tail length of the fetal rats significantly increased in the MDD group (P < 0.05). But the effect of MDD was superior to that of STP (P < 0.05). Moreover, the teratogenic rate was significantly lowered in the MDD group (P < 0.05).
CONCLUSIONMDD could promote the weight gaining of pregnant rats and fetal rats, improve the body length and tail length of fetal rats, and lower the teratogenic rate in fetal mice.
