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 influence of intraoperative posture intervention on drainage in patients after gynecological laparoscopic surgery. Methods A total of 1250 patients who were scheduled for gynecological laparoscopic surgery including laparoscopic-assisted salpingoplasty,oophorocystectomy,ectopic pregnancy,vaginal hysterectomy,myomectomy and appendectomy were randomly divided into two groups. The patients' posture was changed from Trendelenburg position to level lithotomic position during suction by the circulating nurses in the experimental group,while after surgery in the control group. The volume and time of drainage,and the length of stay after surgery were compared between the two groups. Results The volume and time of drainage,as well as the length of stay after surgery had significant differences between the two groups (P<0.05). Conclusions Intraoperative posture intervention is helpful for the treatment effect of drainage after gynecological laparoscopic surgery.

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 The aim of this article is to study the clinical features, image, electroencephalogram and gene mutation of mitochondrial encephalomyopathy with MELAS and to improve understanding of the disease. Methods Clinical data was collected from 12 MELAS cases. Their clinical symptoms, head imageological result,electroencephalo-gram and gene mutation were analyzed. Results The average onset age was 28 years old. The main manifestations of 12 patients were epilepsy(66.7%), stroke-like episodes(50.0%), mental behavious disorder and decrease of perceive (41.7%),diabetes or abnormal glucose tolerance(41.7%), hearing impairment(41.7%). The imaging results showed long T1, long T2 and high signals on DWI. The nidus involved occipital lobe, temporal lobe, parietal lobe most. Five of six cases undergoing MRS imaging had large lactate peak at 1.33 ppm. There were 9 cases carrying mtDNA A3243G muta-tion. Conclusion The clinical presentation of MELAS is highly variable without any obvious specificity on MRI and EEG. Large lactate peak on MRS may indicate the disease. Most patients carry A3243G mutation.
