OBJECTIVE:
To develop a five fluorescence-labeled multiplex amplification system for 15 loci and study genetic polymorphism in Xinjiang Uygur population.
METHODS:
The STR loci were screened. The alleles were named according to the number of repeats by sequencing. The sensitivity, species specificity, identity and stability of the five fluorescence-labeled multiplex amplification system for the 15 loci were all tested. Then, the genetic polymorphism was analyzed in Xinjiang Uygur population and compared with other ethnic groups including Xizang Tibetan, Xiuyan Manchu, and Guangzhou Han population.
RESULTS:
The 15 loci multiplex amplification system was established. The sensitivity was 0.3 ng with good species specificity, identity and stability. The distributions of genotype for 13 STR loci in Uygur population were in accordance with Hardy-Weinberg equilibrium with no genetic linkage between these loci. Most loci showed statistically significant among different populations.
CONCLUSION
The established system has application value in forensic evidence. The 13 STR loci in Uygur population have

Objective To investigate the molecular regulation of G1 arrest of mouse thymocytes induced by ionizing radiation. Methods Cell cycle was analyzed by flow cytometry (FCM) following staining of cells with proidium iodide. Fluorescent staining and flow cytometry analysis were employed for measurement of protein expression. Results It was demonstrated that G1 phase of mouse thymocytes increased significantly at 12h after whole body irradiation (WBI) with the doses of 0.5, 1.0 and 2.0 Gy, and at 24h following 2.0Gy exposure, measured by FCM. In the time course experiment, it was found that G1 phase of thymocytes increased significantly at 4h, reached a peak level at 24h and came down toward 48h after WBI with 2.0Gy X-rays. The results also showed that after 2.0Gy exposure, the expression of proteins in mouse thymocytes increased significantlty from 1h to 8h for p53, for p21 from 4h to 48h, and for MDM2 at 4h and 8h, measured by FCM. But no change was found for GADD45 protein expression. Conclusion These results suggest that G1 arrest could be induced by a single dose of 0.5 Gy, 1.0Gy or 2.0Gy, and its molecular control might be established through the p53-p21 pathway.

OBJECTIVETo evaluate the influence of Shenfu Injection (SHF) on the quality of life of patients with advanced non-small cell lung cancer (NSCLC) receiving chemotherapy.
METHODSA total of 133 patients with NSCLC receiving at least two cycles of chemotherapy with taxol plus cisplatin (TP)/vinorelbine plus cisplatin (NP) or gemcitabine plus cisplatin (GP) were randomized into SHF pre-treatment group (with SHF given only in the first cycle) and SHF post-treatment group (with SHF given only in the second cycle). The Quality of Life Questionnaire-Core 30 (QLQ-C30) and the Functional Living Index-Cancer (FLIC) were used to evaluate the quality of life of the patients after the treatments.
RESULTSBoth of the groups showed improved quality of life after the treatments (P<0.01), but the improvements were more obvious in SHF pre-treatment group (P<0.05). SHF showed favorable effects in relieving such adverse effects as fatigue, nausea, vomiting and diarrhea associated with the chemotherapy.
CONCLUSIONSHF can improve the quality of life in NSCLC patients receiving chemotherapies.

OBJECTIVEBased on magnetic beads based weak cation exchange chromatography (MB-WCX), matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS) and ClinProTools software, the polypeptides of serum about occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) patients were studied, and a diagnostic model of OMLDT was built.
METHODSAccording to diagnostic criteria of OMLDT, serum of 28 OMLDT patients and 28 controls which were diagnosed by Shenzhen prevention and treatment center for occupational disease were collected. With the combination of MB-WCX and MALDI-TOF-MS, the polypeptides fingerprint of serum of 14 OMLDT patients and 14 controls were detected, what's more, the ClinProTools software and SNN algorithm was used for screening characteristic polypeptides and establishing diagnostic model of OMLDT. Then other objects were applied to validate the model to evaluate accuracy.
RESULTSA total of 159 peaks were attained by ClinProTools software, of which 33 peaks were statistical content (P < 0.05). What is more, comparing with the control group, 20 peaks in case group were decreased, and 13 peaks were increased. Two peaks of them were identified, that is 2106.29 and 3263.78, to classify and determine that two groups by receiver operating characteristic curve (ROC) analysis.2D peaks distribution map certified this finding and the area under the ROC curve was closed to 1. A model was established by SNN algorithm, whose cross validation and recognition capability were 87.5% and 98.5%, respectively. Its sensitivity and specificity were 84.8% and 82.1%, separately, which displayed good separating capacity.
CONCLUSIONIn the combination of MB-WCX, MALDI-TOF-MS and ClinProTools software, specifical different polypeptides were screened and OMLDT diagnostic model was built primarily. Also, the model and the results were positively validated, which would play a significant role in early diagnosis.

A silver nanowires(AgNWs) flexible electrode was prepared using polydimethylsiloxane (PDMS) as the substrate and AgNWs as the conductive layer. It is easier to change the shapes and sizes of the flexible electrode due to its excellent stretchability and foldability. A square wave stripping voltammetry (SWSV) method for the detection of trace copper in water was established using the electrode as the working electrode.The characterization of AgNWs flexible electrode showed that the spread of AgNWs was uniform and the average resistance was 1.03 Ω. The data of electrochemical analysis showed that the properties of the electrode were superior to commercialized gold electrode and silver electrode. The effects of Bi3+concentration, supporting electrolyte,pH value, enrichment potential and enrichment time were determined and optimized. We achieved the sharpest and highest peak of the SWSV curves for the detection of Cu2+in the range of-0.3-0.3 V,which means the most sensitive detection, under the following conditions such as 0.5 mg/L Bi3+,0.1 mol/L support electrolyte tartaric acid-sodium tartrate solution (pH, 4.8), 0.6 V of enrichment potential, and 600 s of enrichment time. Under such conditions, the linear detection range of Cu2+concentration was from 0.001 mg/L to 0.100 mg/L and the detection limit was 9.27×10-5mg/L. The advantages of this detection method are fast speed,high sensitivity and wide detection range. Therefore,it can not only meet the requirements for the copper ion detection but also provide a new method or experimental basis for the detection of other metal ions in water. In addition, the AgNWs flexible electrode has great potential in detections under special circumstances or instantaneous detections due to its wonderful flexibility and biocompatibility.
