Objective To investigate whether intrauterine hypoxia and ischemia can produce long-time effects or NOSI can prevent these damages. Methods Fetal rat intrauterine distress model was constructed. The rats were divided into the normal group, hypoxia and ischemia reperfnsion group and treatment group. Pupa were given to surrogate mothers and the ability of learning and memory at 40 day of age after delivery were examined. Then the water maze test was performed to detect the space learning ability and memory function of rats, and the changing of synaptophysin levels in hippocampns were detected by immunohistochemical staining. Result Behavioral results show that fetal distress produces cognitive impairment demonstrated by Morris water maze performance including a higher escape latency score and a de-creased cross platform time. The COD of Syp positive immunoreactive product in hippocampus were less decreased than that in the normal group or NOSI group. But the behavioral results and the COD of synaptophysin had no difference between normal group and NOSI group. Conclusions Fetal distress produced cognitive impairment and led to the decreasing of synaptophysin in hippocampns. Effective measure can relieve these damages.

A comparative study of systemic lupus erythematosus in 39 male(MSLE) and 120 female (FSLE) patients was carried out. The results showed that, in MSLE, the mean age at the time of disease onset was similar to FSLE, and the clinical features were nearly the same as those in females, except that the first signs of MSLE were less complicated than those of FSLE, malar rash occurred less commonly in MSLE than in FSLE(P

Objective To explore the joint toxic effect of formaldehyde and benzene on testicles of the mice. Methods 78 Kunming male mice were divided into groups, in the formaldehyde treatment groups were exposed at dosage of 0.2 mg/kg,2 mg/kg,20 mg/kg, in the benzene treatment groups were exposed at dosage of 100.0 mg/kg,200.0 mg/kg,400.0 mg/kg and the in formaldehyde and benzene combined treatment groups were exposed at dosage of 0.1+50.0 mg/kg,1+100.0 mg/kg,10+200.0 mg/kg respectively. The treatments were conducted by peritoneal injection for five consecutive days,once a day,then killed on 6th day. The activity of superoxide dismutase(SOD),the contents of maleic dialdehyde(MDA),the contents of copper(Cu),zinc(Zn) in testicles of the mice were determined. Results Compared with those in the negative control groups,the activity of SOD and the contents of Cu, Zn in the testicles of the mice in each treatment group significantly decreased, while the contents of MDA significantly increased (P

Sleep disorders are common diseases with various dys-function during sleep-wake process, including difficulty falling or staying asleep, falling asleep at inappropriate times, excessive total sleep time, or abnormal behaviors associated with sleep. Sleep disorders can lead to the deposition of amyloid beta protein ( Aβ) by affecting the normal metabolism of amyloid beta protein in the brain. Patients with Alzheimer’s disease ( AD) often suffer from sleep disorders, and its pathology always results in more se-vere sleep disorders, which leads to a risk of cognitive impair-ment and hypofunction. Sleep disorders could interact closely with AD, forming a positive feedback loop, which causes serious damage to the body health. This review summarized the current research about sleep disorder in the onset of AD and the current status of medication.

Objective To investigate the imaging features of aggressive angiomyxoma.Methods CT findings in 3 patients and MRI finding among one of them with pathologically proved aggressive angiomyxoma were retrospectively analyzed and the relevant literature were reviewed.Results In all the 3 cases,CT and MR imaging demonstrated a well defined mass arising from the pelvis,perineum or vulva.The tumours displaced but did not invade adjacent structures of the pelvic.In 2 cases,there was marked enhancement following injecting contrast materials or T_2WI with internal swirling pattern.Recurrent tumour in one case was of similar imaging features to the primary lesion.The small cystiform area could be seen inside the lesion in one case.Conclusion Aggressive angiomyxoma carries certain characteristics in CT and MRI manifestations.MRI is more excellent than CT in delineating the site,shape and the extent of these lesions.

Objective To investigate serum interferon-inducible protein 16 (IFI16) level in the patients with preeclampsia (PE) and its correlation with PE pathogenesis.Methods Forty-five PE pregnant women in the Third Affiliated Hospital of Zhengzhou University from August 2015 to March 2016 were selected as the PE group and contemporaneous 30 healthy pregnant women undergoing the routine pregnant examination were selected as the control group.The biochemical indexes of serum urea,uric acid,creatinine,etc.were detected by using the automatic biochemical analyzer.The serum levels of IFI16 and ET-1 were measured by ELISA.Then the correlations between serum IFI16 level with these detected indicators were analyzed.The receiver operating characteristic (ROC) curve analysis was performed to evaluate the value of serum IFI16 for predicting PE disease.Results The serum IFI16 and ET-1 levels in the PE group were significantly higher than those in the control group (P<0.01).Furthermore the serum IFI16 level in severe PE was significantly higher than that in mild PE (P<0.01).Serum IFI16 level in PE was positively correlated with systolic blood pressure,diastolic blood pressure,24-h urine protein quantitation and serum ET-1 level,and negatively correlated with serum albumin.Serum IFI16 levels 14.47 ng/mL and 17.09 ng/mL as the critical values for predicting preeclampsia and discriminating between mild preeclampsia and severe preeclampsia has a higher sensitivity and specificity.Conclusion The high level of serum IFI16 in pregnant women has a certain correlation with PE pathogenesis and may be a novel biomarker for predicting PE occurrence.

Through the investigation of Phellodendron Cortex on the market, and 28 batches of samples were collected. By using spectrophotometer the color values of outer surface, inner surface and cross - section of these samples were measured. These measured color data was translated into 3D structure diagram by using the Lab color space tool. The level difference value, the mean value and the threshold value were calculated based the measured color data of these different batches of samples. All 28 groups measured data was analyzed using the methods of Ward linkage and average Euclidean distance. At the same time, we invited Professor Jin Shiyuan, the "Chinese medicine master", to identify, quality-evaluate and grade these 28 batches of Phellodendron Cortex samples base on the traditional experience, then compared the traditional empirical results with the spectrophotometer measurement results. The result showed that, the Phellodendron Cortex could be divided into Phellodendri Amurensis Cortex and Phellodendri Chinensis Cortex by color numerical clustering, and classified according to quality. The classification result has a high degree of consistency with the traditional experience.

To make a systematic analysis on literatures concerning traditional Chinese medicine (TCM) advices in Treatise on Febrile Diseases, and summarize the main connotations of traditional Chinese medicine advices, relevant TCM advices in Treatise on Febrile Diseases were collected, screened, compared, summarized and analyzed according to TCM dosage form preparation methods, TCM administration methods, medication contraindications and nursing after TCM administration. The literatures concerning medications in Treatise on Febrile Diseases were consulted, summarized and compared to standardize medicine advices and facilitate rational clinical application of TCMs. The standard medicine advices were as follows. The boiling water for TCMs shall be tap water and well water. The decoctions that have effects in promoting blood and meridians can be boiled with wine. The decoctions containing toxic components can be boiled with honey. Some TCMs shall be boiled with special methods, e. g. Herba Ephedra that could be boiled before other medicine and skimmed. Japonica rice could be added in decoctions to measure the duration of decoctions. Different dosages were required for different forms (litre, pill, medicine spoon). Administration times, temperature and frequency shall be adjusted according to target positions, functions and stage of illness. As for dietary contraindications during medication, thick porridges are recommended, where foods impacting medicine efficacy are prohibited. Regarding nursing after medication is important to recover physical functions, particularly warm porridges can go with diaphoretic recipes, while thick porridges can go with purgative recipes. And drug efficacies shall be defined by observing urine and excrements, and blood form. In conclusion, Treatise on Febrile Diseases is the first book that discusses TCM advices and records them in details. In this study, new standard medicine advices were proposed to provide important basis for improving clinical advices of TCMs and supports for developing the TCM dispensing technology.
