Objective To study the effect of herbal reyanbao combined with rehabilitation training on the rehabilitation of patients with lumbar disc herniation.Methods 120 cases with lumbar disc prolapse as the research object from January 2015 to December 2016 in Wuhan integrated traditional Chinese and western medicine hospital were divided into two groups(the control group and the observation group).The control group were treated with routine conservative+conventional nursing plan, and the observe group were given herbal reyanbao combined with rehabilitation training.Clinical data were compared in the two groups.Results The clinical effect and rehabilitation degree in the observation group were better than those in the control group, the difference was statistically significant(P< 0.05).Conclusion It can help patients with lumbar disc herniation recover as soon as possible which herbal reyanbao combined with rehabilitation training were used on the rehabilitation of patients, and it is worthy of application.

The aim of this paper is to apply Raman spectroscopy technique to develop rapid quantitative models for five kinds of Traditional Chinese Medicine containing CaCO3. In the experiment, Raman spectras of 67 batch of sample including Otolithum Sciaenae, Galaxeae Os, Ophicalcitum, Calcite, Stalactite and their mixture which had different content of CaCO3 were collected, and the quantitative models were established by using an improved siPLS to optimize the characteristic spectral bands and using the CaCO3 contents which were measured by EDTA titration method as references. Compared with the results by EDTA titration, the established quantitative model for CaCO, content showed a prediction result that the average relative deviation of the prediction results is 2. 71% and the average recovery rate was 100.46%, when the content is between 0.465 4-0.999 7, and when the characteristic spectral bands of 1 290-1 280, 730-714, 700-690, 660-650, 465-460, 455-445, 405-385 cm(-1) had been optimized. The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

Objective To evaluate the value of DWI in assessing the biological characteristics of breast invasive ductal carcinoma (IDC).Methods Eighty-seven IDC lesions confirmed by postoperative pathology were involved in this retrospective study.The ADC values of IDC were compared among different lymph node status,grades,and molecular subtype.The correlations of ADC value and lymph node status,grades,and molecular subtype were evaluated.Results The ADC value of IDC with positive lymph node was lower than that with negative lymph node (P=0.035),and the ADC value of the high grade IDC was lower than those of medium grade IDC and low grade IDC (P=0.021,0.002).There was no significant difference of ADC value between different molecular subtypes.There was low negative correlation of ADC value with grades (r.s =-0.357,P 0.001) and week negative correlation of ADC value lymph node status and nolecular subtype (rs =-0.227,P=0.034;rs-0.093,P＜0.001).Conclusion DWI can provide useful information in evaluating the biological characteristics of IDC.

Objective To investigate the relationship between spontaneous miscarriage and embryonic chromosome abnormalities,and to evaluate the clinical application of karyotype analysis by chorionic villus cell culture. Methods The chorionic villus karyotype of 1983 cases of miscarriage from January 2010 to July 2016 in Guangzhou Women and Children′ s Mecical Center were analyzed retrospectively. The miscarried chorionic villi were obtained by curettage under sterilized condition. The chromosome specimens were prepared after chorionic villus cell culture. Karyotype analysis was performed by G-banding technique. Results In the 1983 samples, successful karyotype analysis was performed in 1770 cases, with the successful rate of 89.98%. Chromosomal abnormalities were found in 1038 cases (58.64%,1038/1770). Chromosomal structural abnormalities were found in 37 cases. The numeral abnormalities were more common than structural abnormalities, and most of the numeral abnormalities were aneupoidies. In turn, they were trisomy 16, 45,X, trisomy 22, trisomy 2, trisomy 21, trisomy 15. The most common structural abnormality was balanced translocation, including Robersonian translocation. Female embryoes accounted for 61.02%(1080/1770) miscarriages and for 57.4%(596/1770) of chromosomal abnormalities, while male embroyes acoounted for 61.02%(1080/1770),57.4%(596/1770)respectively. The proportion of female embryoes was higher than male embryoes. The median age of the patients was 30 years old(16-46 years old). As the maternal age increased, the proportion chromosomal abnormalities increased. The incidence of chromosomal abnormalities in the advanced age group (≥35 years) was 68.38%(240/351), which was significantly higher than that in the younger group (56.24% ,798/1419; χ2=17.10, P<0.01). Conclusions Embryonic chromosomal abnormalities are the most common cause of early spontaneous miscarriage. The abnormalities centralize in some karyotypes. There is certain relationship between maternal age and the incidence of miscarriage, as well as the embryonic gender. Chorionic villus cell culture and karyotype analysis are helpful in finding the cause of miscarriage and counsel the patients.

OBJECTIVE: To evaluate the effect of aerobic exercise on genome expression in human skeletal muscle. METHODS: Six healthy sedentary elderly men aged (66+9) years were selected from military cadre retirement centers and after exercise. Testing indices included height, weight, vital capacity, step index and maximal oxygen uptake. Needle biopsies were obtained from the skeletal muscle before and after the last training. Total RNA extracted from the samples was hybridized to Affymetrix U 133A platform, the gene expression datum was analyzed.RESULTS: Aerobic exercise was shown to improve cardiorespiratory function and reduce body fat of elder subjects. It could alter the genome expression in human skeletal muscle, the number of genes that passed filtering criteria was 725. The most differently expressed genes (n=20) were investigated in this study, in which there were 3 upregulated and 17 downregulated. According to gene function annotations, the differential genes were classified into 8 categories which concerned cellular component and biological process, Kyoto Encyclopedia of Genes and Genomes (KEGG) searching showed 4 genes' metabolism pathway. CONCLUSION: Systematic aerobic exercise upregulates expression of enzyme genes concerning tricarboxylic acid cycle, and downregulates expression of genes conceming muscle protein synthesis and sphingolipid. It is suggested that aerobic exercise is good to protect human nerves' integrity, exerts positive action on anti-aging and accelerate the aerobic metabolism of lipid materials in vivo.

Objective To investigate the mechanism of quinolone resistance in Psendomonas aeruginosa.Methods The minimum inhibitory concentrations (MICs)of ciprofloxacin and levofloxacin with and without carbonylcyainde-m-chlorophenylhydrazone(CCCP)were determined by agar dilution method.Polymerase chain reaction(PCR)and DNA sequencing were used to study the mutations in quinolone resistance-determining region of gyrA and parC genes.The strains were genotyped by enterbacterial repetitive intergenie consensus-PCR(ERIC-PCR).Results Sixteen quinolones-resistant Pseudomonas aeruginosa strains were obtained.The MICs of ciprofloxacin and levofloxacin were not reduced significantly by adding CCCP.Thr-83→Ile of gyrA and Ser-87→Leu of parC were found simultaneously in 16 strains of resistant Pseudomonas aeruginosa.Analysis of ERIC-PCR products indicated that 16 quinolone-resistant strains had an identical band pattern which was different from that seen in the sensitive strains.Conclusion Mutations in gyrA and parC may be the main mechanism of quinolone resistance in clinical isolates of Pseudomonas aeruginosa.
