ObjectiveTo analyze the mental health level and the correlative factors of elderly reflux esophaditis patients.Methods86 elderly reflux esophagitis patients were tested with Symptom Check List-90 (SCL-90) and the Correlative Factor Inquiry List.ResultsThe total SCL-90 scores of the patients was 137.5±27, the number of symptomatic items was 29.9±17, which was significantly higher than that of domestic norm ( P<0.01). Besides of psychopathic and phobic, other factor scores of SCL-90 were also significantly higher than that of domestic norm ( P<0.05～0.01). The somatization, depression and anxiety were first three factors according to significant level. The constitution of patients showed the normal distribution at the level of total SCL-90 score.ConclusionMental health level of elderly reflux esophaditis patients is lower than that of normal people. The two primary reasons are long-term trend and stress of disease.

Objective To investigate whether high glucose can induce endothelial-mesenchymal transition (EndMT) in glomerular endothelial cells and the role of TGF-β in the process.Methods Rat glomerular endothelial cells were divided into five groups:normal glucose (NG,5.5mmol/L),high glucose (HG,15,30 mmol/L),TGF-β inhibition (HG+ LY36,30 mmol/L glucose + 10 μmol/L LY364947),hyperosmotic control (M,5.5 mmol/L glucose+25.5 mmol/L mannitol) and solvent control (D,5.5 mmol/L glucose + 1 ml/L DMSO).Western blotting was performed to detect relative protein quantities of endothelial marker claudin 5 and mesenchymal marker α-smooth muscle actin (α-SMA).TGF-β1 and TGF-β2 mRNA levels were measured by real-time PCR.Vascular endothelial marker VE-cadherin and mesenchymal marker α-SMA were detected by immunofluorescent stain and observed by confocal microscopy.Results Compared with NG,the expression of claudin5 protein in HG (15 or 30 mmol/L) was up-regulated while expression of α-SMA protein was down-regulated (P ＜0.05).Both TGF-β1 and TGF-β2 mRNA levels increased as well (P ＜ 0.05).However,when compared with HG,the claudin 5 levels increased while α-SMA decreased in TGF-β inhibition group.No significant changes were observed in hyperosmotic or solvent control group.Confocal microscopy showed the transformation of cells from a cobblestone-liked shape to a spindle one,and a decreasing expression of VE-cadherin while an increasing α-SMA in HG group (P ＜ 0.05),whereas TGF-β inhibition partly attenuated those changes in both morphological and protein levels.Conclusions High glucose treatment of glomerular endothelial cells results in an increase in the level of TGF-β1 and TGF-β2 mRNA and leads to endothelial-mesenchymal transiton.Inhibition of TGF-β partly prevents this process,indicating that TGF-β plays a crucial role in high-glucose-induced glomerular endothelial-mesenchymal transiton.

Objective To investigate the methods of reducing radiation dose in CT coronary angiography through optimizing individualized scan dosage protocol.Methods Two hundred patients (group A)underwent coronary CTA examination which was performed with fixed 120 kV and variable mA according to their BMI.The mA was set as 150-300 mA(BMI ＜ 18.5 kg/m2),300-500 mA (18.5 kg/m2 ≤ BMI ＜ 25.0 kg/m2),and 500-800 mA(BMI ≥ 25.0 kg/m2).When all examinations were finished,a linear regression was employed to analyze the correlation between mA and BMI,body surface(Suf),image noise(SD)respectively.The results of the analysis were used to formulate a regression equation,which was further used to establish a table list for quick search on how much mA that individualized coronary CTA scan would need.Another 200 patients(group B)enrolled for the individualized scan were scanned under new protocol that previous study established.The tube voltage was 100 and 120 kV.The tube current was variable according to the data in the table list.One-way ANOVA and Kruskal-wallis H test were used for statistics.Results Regression equation between mA and BMI,Suf,SD was:mA =17.984 × BMI + 169.149 × Suf-2.282 × SD-361.039.The SD(group A:32.08 ± 5.80,group B:28.60±4.47),dose index volume(CTDIvol)[group A:(41.97 ± 11.37)mGy,group B:(33.18±10.07)mGy],effective dose(ED)[group A:(10.91 ±3.07)mSy,group B:(8.83 ±2.72)mSv]had significant differences between the two groups(F =43.45,63.71,49.07 respectively,P ＜0.01 for all).The SD and ED results obtained in group B were better than those in group A.Conclusion Better performances were obtained when BMI combined Suf was used as a new individualized protocol than when BMI was used only,which means good image quality and lower radiation dosage in coronary CTA examination.

OBJECTIVETo compare the effect,safety,and advantage of flexible fixation with paperboard and pad versus short leg plaster in treating the fifth metatarsal base fracture,and establish the standard of diagnosis and treatment of the fifth metatarsal base fractures in flexible fixation with paperboard and pad.

METHODSFrom June 2010 to March 2013,59 patients with the fifth metatarsal base fracture were treated with paperboard and pad fixation or short leg plaster. Patients were enrolled and divided into paperboard and pad treatment group (paperboard group) and short leg plaster treatment group (plaster group) randomly according to the random number table. In paperboard group,there were 29 cases including 9 males and 20 females with an average age of (51.79±11.40) years old; the average course of injury was (11.59±6.58) hours. In plaster group, there were 30 cases including 9 males and 21 females with an average age of (52.13+17.34) years old ;the average course of injury was (11.03±7.06) hours. According to whether the fracture line across the articular surface, in paperboard group there were 14 cases of type A,15 of type B; in plaster group,16 of type A, 14 of type B. According to the degree of dislocation,in paperboard group there were 16 cases of degree I ,13 of degree II ; in plaster group,20 were degree I ,10 were degree II. Fracture was restored according to the type in manual. Patients in paperboard group were treated with paperboard and pad, and patients in plaster group were treated with short leg plaster. Fracture was fixed for 4 to 6 weeks according to fracture healing. On the 2nd, 4th,6th, 8th week and 3rd, 6th month after fixation, patients were followed up, and the foot function score was used to evaluate the function of injured foot. X-ray of injured foot was taken on the 2nd, 4th, 6th and 8th week were used to assess fracture healing.

RESULTSAll patients got complete follow-up. The X-ray result showed that all fracture reached at clinical healing on the 8th week after fixation without skin ulcer,nonunion and displacement of fracture. From the 4th to 8th week after fixation, paperboard group had a higher X-ray score than plaster group, but the difference between two groups had no statistically significance. Repeated analysis result showed that there was interact at different time point and between groups,the difference had statistically significance (P<0.01). The foot function score showed that at all time point, paperboard group had a higher score than plaster group, and on the 2nd, 4th, and 6th week, it had statistically significant difference(P<0.01) between two groups. On the 6th months after fixation,the excellent and good rate of paperboard group was 93.10%, higher than that of plaster group, which was 86.67%. But it had no statistically difference(P=0.483) between two groups.

CONCLUSIONUsing paperboard and pad fixation to treat the fifth metatarsal base fracture has the advantage of simplicity operating,reliable fixation, satisfactory effects, easily obtainable material.

Objective To explore the mutation of Y-STR loci in meiotic allelic transmission in a large pedigree. Methods The oral swabs of 163 male individuals were collected froma L in pedigree. Twenty-two Y-STR genetic markers were typed with AGCUY 24 fluorescent detection kit (AGCUY 24 sys-tem), which also contained 16 Y-STR markers included in Y filerTmmultiple amplification kit (Y filer system). The genotyping results of Y-STR loci were compared between each two males in the pedigree. Results There were 20 and 30 kinds of haplotypes obtained with Y filer and AGCUY 24 systems in 163 male individuals fromthe L in pedigree, respectively. The rates referred to haplotype differences (RRHD) of these two typing systems between male pairs were 0.910 5 and 0.922 7, respectively. The average number of marker differences were 6.582 1 and 9.824 8, respectively. The RRHDincreased along with the incidents of meiosis. Conclusion Y-STR mutation leads to different Y-STR haplotypes among the male members in a paternal pedigree and the rate of difference increases along with the incidents of meiosis.

OBJECTIVETo explore the technique of induction of polyploidy in Salvia bowleyana by colchicine treatment.

METHODThe three kinds of explant of bud, leaf and calli were induced by colchicine treatment.

RESULTThe induction effects were better when the calli was treated by colchicines (15 mg x L(-1)) and the leaf was pre-cultured for one week. The doubling rate was 33.33%, while the majority were wholy doubled plants, and the leaves were thicker and broader, the color was darker, the root was thicker and the stoma size was obviously bigger than the diploid plants. The number of chromosome were 8 to 64. Isoenzyme analysis showed that the enzyme activities between the polyploid and the diploid plants were quite different.

CONCLUSIONInduction of polyploidy by colchicine treatment is efficacious. The part of the doubled plants were identified as homologmous tetraploids.

Sini decoction (SND), a classical traditional Chinese medicine emergency formula recorded in Shanghan Lun (Treatise on Febrile Diseases), which is composed of Aconiti Lateralis Preparata Radix, Glycyrrhizae Preparata Radix and Zingiberis Rhizoma. Modern clinical and pharmacological researches have shown that SND can protect the myocardium effectively during myocardial ischemia reperfusion injury (MI-RI). A myocardial ischemia reperfusion injury model of H9c2 cardiomyocytes in vitro has been established. Four groups, control group, MI-RI Model group, SND group and SND without Glycyrrhizae Radix group, were arranged. The livability, the level of LDH and CK activity in H9c2 cardiomyocytes in different groups were tested. By combining with principal components analysis (PCA), partial least squares discriminant analysis (PLS-DA), orthogonal partial least squares projection of latent structures-discriminant analysis (OPLS-DA), 17 biomarkers in extracellular fluid were identified and 15 of them were related to the pathway of biological processes. The results showed that the attenuate and synergistic mechanism between Aconiti Lateralis Praeparata Radix and Glycyrrhizae Radix for toxicity reduction was related with the glycolysis, lipid metabolism, citrate cycle and nitrogen metabolism of amino acids metabolism. The study proved the effect on H9c2 cardiomyocyte treated by MI-RI injury both SND group and SND without Glycyrrhizae Radix group, and compared with the SND without Glycyrrhizae Radix, the protective effect of myocardial ischemia reperfusion injury model of H9c2 cardiomyocyte from SND was stronger.

Flow cytometry was previously applied for analysis of Rh(D) antigen density, therefore it was suggested that the flow cytometry may be used for routine detection of weak D positive phenotypes. This study was purposed to evaluate its practicability. Six weak D positive and 7 DEL individuals were detected by using saline, IAT and absorption/elution test from 2010 to 2011 years. By RHD genotyping, zygosity analysis and sequencing, 3 cases of weak D type 15, 3 cases of partial D type DVI-III and 7 cases of DEL carrying RHD1227A alleles were identified. Taking 2 normal Rh(D)-positive and 2 D-negative samples as controls, all the samples were tested by using flow cytometry, and the median fluorescence intensities were observed as well. The results indicated that all weak D type 15 and partial D type DVI samples were detected to be positive by flow cytometry, as compared with 2 Rh(D)-negative samples (P < 0.05). Seven 7 DEL samples were tested to be negative (P > 0.05), although one of 7 DEL was tested as "±" in IAT and strong positive in absorption/elution. The RHD zygosity analysis showed this DEL individual as RHD(+)/RHD(+) homozygote. It is concluded that the sensitivity of detecting D antigen by flow cytometry is similar to that of IAT, but lower than absorption/elution test. As for detecting weak D or partial D antigens, IAT is easier than flow cytometry; as for identifying DEL, the flow cytometry is not sensitive enough.
