Objective To study the effect of pinealctomy and melatonin on the cell cycle distribution during T cell development in thymus. Methods SD rats were divided into 5 groups:normal controls,sham-operated controls,pinealectomy,pinealectomy+melatonin injection 7.5 mg/kg; and pinealectomy+melatonin injection 15 mg/kg.The animals were sacrificed at 4 or 8 weeks after operation.cycilnA +and cyclinE +T cells in thymus were dyed with immunocytochemical ABC methods, measured by computer image analysis.Cell cycle analysis was performed by flow cytometry.The expression of cyclin-dependent kinase inhibitor 1? was tested by RT-PCR method. Results The effect of pinealectomy on the expression of cyclinE was stronger than that of cycilnA. Pinealectomy promotes the synthesis of cyclinE in thymus.The percentage of G-0/G-1 phase cells was decreased and G-2/M phase cells was increased.These would be convalescente by supplement with melatonin,but the reaction to melatonin was differencet in thymus cortex and in medulla.Melatonin enhanced the expression of cyclin-dependent kinase inhibitor 1? in thymus.Conclusion Pinealectomy influences notably the T cells development in thymus.Rejuvenation of degenerative thymus could be observed by melatonin administration.

AIDS antiviral therapy (ART) has achieved great success.Originaly,AIDS had been regarded as a fatal disease,but it has become a kind of infectious disease that could be cured and administrated.Global HIV / AIDS cases were still up to about 38 million,but more than half have been effectively treated.In addition to drug treatment,at present,some new technologies and new methods,such as genome editing,have also been involved in the treatment of AIDS,and in the humanized animal experiment has shown very good results.There is no doubt that AIDS will eventually be stopped its epidemic.However,with the continuous development of AIDS antiviral treatment,the most fundamental problem is that HIV latent library has become increasingly prominent one,whether molecular therapy and hybrid cure have being developed for AIDS treatment,there are still such problem existence.Great efforts shoud be made to continuously search for new markers of latent viral cells and to reduce the latent pool.In addition,despite the prevention and treatment of AIDS has made great achievements,but the world still produces nearly 6000 cases of HIV/AIDS every day.Therefore,the development of safe and effective vaccine,whether in the field of prevention,or in clinical treatment,has its positive significance.

A 38-year-old woman presented with a 20-year history of yellow papules and band-like atrophy on the right neck. The lesions developed slowly and were asymptomatic. There was no history of long-term sun exposure or family history of similar diseases. Skin examination revealed multiple irregularly sized yellow papules and plaques on the right anterior neck following cleavage lines, multiple pin cap-sized perifollicular papules on the posterior right neck. Well-defined band-like atrophic patches with fine wrinkling were observed in the whole right neck, giving an aged appearance. The skin of the left neck was nearly normal. Pathological examination of biopsy specimens from the yellow papules showed a normal epidermis, scant lymphohistiocytic and melanophage infiltrates around the vessels in the superficial dermis without solar degradation. The collagen bundles in the mid dermis were slightly thickened and arranged tightly in parallel to the skin surface with the absence of inflammatory infiltrate. Verhoeff-van Giesen's staining confirmed a nearly complete absence of elastic fibers in the mid dermis as well as obvious swelling and breakage of resident scant elastic fibers. Von Kossa's staining was negative. Based on the above findings, the diagnosis was made as unilateral mid-dermal elastolysis.

Objective To explore the clinical value of color Doppler flow imaging(CDFI) combined with quantitative analysis technique to evaluate renal flow perflusion. Methods Twenty patients with different renal diseases matched with healthy control subjects were examined with Philips iU22 CDFI system. CDFI system and Qlab quantitative technique were used to measure renal restrictive index(RI), vascularization index(VI), flow index(FI), vascularization-flow index (VFI). The patients all received renal single-photon emission computed tomography (SPECT) examination. Results The RI of 32 kidney with lower flow perfusion in SPECT were higher than in the contol group (P <0.01). VI,FI, VFI were lower than those in control(VI, VFI, P <0.01 ;FI, P <0.05). Conelusious The renal blood flow perfusion of patients with renal diseases are lower than that of healthy people. It has high clinical value using CDFI combined with quantitative analysis technique to evaluate the renal perfusion of the patients with renal diseases.

Objective To investigate the status quo of oral nursing in the emergency department of top three hospitals in Shanxi province, and to analyze the existing problems so as to provide the basis and reference for improving the clinical operation standard. Methods In the form of WeChat questionnaire, a questionnaire survey was conducted to investigate 190 nurses who met the requirements in emergency departments of 6 top three hospitals in Shanxi province. Results All the 6 hospitals surveyed did not incorporate oral care into the nurse examination program; 28.42％(73/190) of the subjects had oral assessments of endotracheal intubation according to their clinical experience;chlorhexidine (70.00％,133/190) and physiological saline (65.79％,125/190) were the most commonly used oral care solutions in clinic;48.42％(92/190) of nurses performed this operation for 6-10 min;91.58％(114/190) of nurses believed that oral care played an important role in the recovery of these patients. Conclusions The oral care and oral care of the patients in the emergency department are mostly clinical experience, so it is urgent to establish a unified standard of implementation on the basis of evidence. The professional knowledge of oral nursing of the patients undergoing oral trachea intubation is low, so it is suggested that the training of emergency nurses be strengthened and the operation should be included in the assessment of nursing operations.

ObjectiveTo observe female university students' differences of cognitive mechanism in processing different types of sexual picture from International Affective Picture System (IAPS).MethodsUsing event related potential (ERP),the differences of the amplitudes of N2,P3 and PSW were examined induced by the neutral pictures and different types of erotic pictures.ResultsThe amplitudes of N2 ( (0.99 ±1.69 ) μV) and P3 ( ( 17.27 ± 1.45 ) μV) elicited by heterosexual couple erotic pictures were highest,followed by the male erotic pictures( ( -0.02 ± 1.83 ) μV,( 15.92 ± 1.26 ) μV),and then were the female erotic pictures ( ( -0.22 ± 1.56)μV,( 15.49 ±1.34) μV).There was statistical significance in N2 and P3 between heterosexual couple erotic pictures and female erotic pictures ( P ＜0.05 ).There was no significant difference in PSW component between heterosexual couple erotic pictures( ( 15.22 ± 1.98 ) μV) and female erotic pictures ( ( 14.53 ± 1.75 ) μV ),but the PSW induced by male erotic pictures (( 10.93 ± 2.60 )μV) was significantly smaller than the other sexual pictures (P＜0.05).ConclusionThe level of sexual arousal elicited by explicit heterosexual couple erotic pictures is highest and also the attention maintains longest.

Skin sensitization (allergic contact dermatitis, ACD), is a serious condition caused by small reactive molecules and is characterized by a delayed-type hypersensitivity .Animal tests were usually used in the evaluation of sensitizing potential of chemical substances in the past .However , there is an increasing interest from the public for reducing and ultimately replacing animal tests .The European Union (EU) has posed a ban on animal testing of cosmetic ingredients that includes skin sensitization since 2013.Therefore, alternative in vitro tests are the main tendency in chemical substances and cosmetic sensitizing potential research in the future .In this study, different kinds of in vitro test methods that were adopted by OECD or on research (LLNA, DPRA, KeratinoSens TM, h-CLAT) were reviewed through recent years literature , comprehensive introduction and evaluation were made to obtain reliable hazard and potency information on potential skin sensitizers .

Objective To evaluate the effect of different kind of intravenous immunoglobulin (IVIG) therapy in treating Kawasaki disease (KD) and preventing cardiac consequences (coronary artery lesion, CAL). Methods A questionnaire form and guideline for KD diagnosis were sent to 50 hospitals providing pediatric medical care in Shanghai. The data from a total of 1 682 KD patients were collected. It included 1 064 males and 618 females from 1998 through 2008 in Shanghai. The average age of the KD patients was (2.57±2.33) years old (0.1-18.8 years).The patients had been divided into 6 groups for different IVIG therapy, which included 1 g/kg once, 2 g/kg once, 0.4-0.5 g/kg five times, 1 g/kg twice, 2 g/kg twice and others. SAS 6.12 software was used for statistical analysis. Results In all KD patients, the patients treated with IV1G in 5th-10th day of illness has the least cardiac complication and CAL incidence and the group with IVIG therapy of 1 g/kg twice also has the least cardiac complication and CAL incidence. Conclusions The best doses of IVIG in treating KD is 1 g/kg twice and the IVIG therapy should be used in 5th-10th day of KD illness.

To investigate the correlation between the number of peripheral blood circulating tumor cells (CTCs) and clinicopathological features of early breast cancer. 
 Methods: The clinical and pathological data from 100 patients with early breast cancer treated by a breast cancer treatment team in the Department of Breast Surgery, Second Xiangya Hospital, Central South University, were collected from January 2017 to December 2018. For these patients, their peripheral blood CTCs were detected, enumerated and typed by CanpatrolTM CTC assay.
 Results: The positive rate of CTCs was 90% in peripheral blood of patients with early breast cancer, and the majority of molecular phenotypes was hybrid CTCs (55.6%). The positive rate of CTCs was only related to the pathological type of tumor (P<0.05), but not to other clinicopathological features. No correlation between clinicopathological features and the total number of CTCs, the number of epithelial CTCs or the number of hybrid CTCs was found. However, the number of mesenchymal CTCs was significantly correlated with the expression of hormone receptors and Ki-67 (r=0.200, P<0.05), and there was a significant correlation between the proportion of mesenchymal CTCs and the expression level of Ki-67 (r=0.213, P<0.05).
 Conclusion: The number of CTCs is not correlated with all clinicopathological features, but patients with negative hormone receptor and high expression of Ki-67 probably have more hybrid CTCs.
