1.Application of neutrophil CD64 on the diagnosis and treatment of infectious diseases
Chinese Journal of Laboratory Medicine 2016;39(5):340-343
The early diagnosis of serious infection is very important since the fatality rate is quite high.Traditional diagnostic methods of infection includes procalcitonin,leukocyte count,CRP and so on,of which the sensitivity and specificity is not able to achieve the early diagnosis.Recently,neutrophil CD64 has been widely concerned for the high sensitivity and specificity in early diagnosis of bacterial infection.Flow cytometry is applied to detect neutrophil CD64 in early diagnosis of infectious diseases including respiratory infection,septicemia,neonatal intensive infection,burn and postoperative infection.What's more,the sensitivity and specificity can be further improved if neutrophil CD64 was combined with other inflammatory markers.Thus,neutrophil CD64 detected by flowy cytometry plays an important role in the diagnosis,monitoring,prognosis,therapeutic effect evaluation of infectious diseases.

ObjectiveTo obsrve the clinical efficacy of acupuncture, herbal medicine, plus Ethinylestradiol and Cyproterone Acetate tablets in treating infertility due to obesity-type polycystic ovary syndrome (PCOS).MethodA hundred elegible patients were divided into a treatment group and a control group according to their visiting sequence and random number table. The two groups both received oral administration of Ethinylestradiol and Cyproterone Acetate tables for 3 months. Afterwords, the treatment group was given Chinese herbal medication and acupuncture, while the control group received oral administration of Metforminand Clomiphene plus muscular injection of human menopausal gonadotropin(HMG) and human choionic gonadotropin (HCG). Both groups received a 3-month course. Before and 3 months after the intervention, serum sex hormones were detected, including:follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), estrodiol (E2), and prolactin (PRL); fasting sugar, sugar tolerance, and insulin release were measured; ovulation, pregnance rate, and total effective rate were calculated.ResultAfter intervention, there were significant differences in comparing LH, LH/FSH, ovulation, and the incidence of follicle hyperstimulating syndrome between the two groups (P<0.05); there were no significant differences in comparing sugar metabolism, insulin release, comprehensive efficacy, dominant follicle count, and pregnancy rate(P>0.05). After intervention, the LH and LH/FSH levels were significantly changed in the treatment group, while the LH and LH/FSH levels, ovulation, and dominant follicle count were significantly changed in the control group (P<0.05), but pregnancy rate and follicle hyperstimulating syndrome were insignificantly changed in both groups (P>0.05).ConclusionCombination of acupuncture, Chinese herbal medicine, and Ehinylestradiol and Cyproterone Acetate tablets can down-regulate the LH and LH/FSH levels, andenhance ovulation, without causing follicle hyperstimulating syndrome.

E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.

Objective To investigate the effect of triptolide on asthmatic airway remodeling and signal transducer and activator of transcription 6 (STAT6), acid neutrophil chemokines (eotaxin) impact. Methods The total of 30 mice with ovalbumin (OVA) model of asthma were randomly divided into three groups, control group, asthma group and triptolide group. After 24 hours of the last shot, lung tissue was stained Bronchial inflammatory cell infiltration was determined by using semi-quantitative method and calculate the proportion of goblet cells in airway epithelial cells. Hydroxyproline was determined by McMillan airway mucus score. The mRNA level and protein level of STAT6 and eotaxin in airway epithelium were determined by RT-PCR and immunohistochemistry. Results Compared with asthma group, peribronchial inflammatory cells infiltration of triptolide group were reduced, which mucus index is (1.31 ± 0.23) and hydroxyproline is (284 ± 13) μmg/100 mg. it had a significant in asthma group (P < 0.05). Besides, the protein level and mRNA level of STAT6 and eotaxin were significantly decreased (P < 0.05). Moreover, it was a positive correlation between STAT6 and eotaxin level in airway epithelial (r = 0.668, P < 0.05). Conclusion Triptolide can inhibit airway remodeling and might through the down regulation of STAT6 and eotaxin expression.

Objective To explore the effect of bone marrow stromal cells (BMSC) transferred by Nell-1 gene combined with biomaterial fibrin glue (FG) to enhance segmental bone defect healing in dog mandible. Methods Nell-1 gene vector was reconstructed in retroviral vector and then transfected BMSC. The protein of Nell-1 gene in transferred cells was determined by immunohistochemistry. Segmental defects were created surgically in the dog’s mandible. The defect was repaired with BMSC transfected by Nell-1 retroviral granules in presence of FG,untransfected BMSC in combination with FG,and FG alone. The control group was left untreated. The defect-repairing capability for each treatment were assessed by gross observation,radiography,and histology at 8th week and 16th week. Results Cells transfected by Nell-1 retroviral granules expressed abundant Nell-1 mRNA and protein in the cytoplasm. Positive results were not found in those cells that were not transferred. The use of BMSC transferred by Nell-1 retroviral granules combined with FG materials exhibited the strongest defect-repairing ability. Gross observation,radiographical and histomorphometric analyses revealed a significantly greater total area of bone formation,increased amount of the new bone in the defects than in those treated with the untransfected BMSC. Conclusion Nell-1 gene transfection may be used to promote the osteogenic ability of BMSC.

medial distal wall. The root canal length of central and lateral incisors were (12.96?6.46) mm and (11.47?6.32) mm respectively. The double root canal was found in 35.9 % of central incisors and in 27.5% of lateral incisors. Most mandibular incisors with long concavity had single root canal. Conclusion: The root canal wall of mandibular incisors was thinner in medial and distal wall than in lingual and labial wall. Mandibular incisors have higher rate in double root canal and the long concavity is not significantly related with number of root canal.
