Objective To study the psychological experience of patients infected with human immunodeficiency virus (HIV) and provide theoretical basis for clinical care.Methods The phenomenological research method was used to interview 9 patient in depth.The Colaizzi 7-step analysis method was used to analyze their clinical data.Result The mental experience of the AIDS patients after notification of affirmative diagnosis of AIDS included six aspects:concealing,suspicion or denying,worry of being abandoned,eager to be cured,calm and worry of communicating the disease to their family members.Conclusion The nurses should pay attention to their mentality,helping them build a social supporting system and supporting pertinent interventions according to individual psychological experience,which is helpful for controlling risks of disease transmission and improving treatment compliance.

No specific causative gene has been found for epilepsy or autism,while the co-occurrence rate of these two disorders is approximately 30％,suggesting potentially shared common mechanisms.A number of well-known genetic disorders share epilepsy and autism as prominent phenotypic features,including Rett syndrome,tuberous sclerosis,fragile X,and so on.A lot of gene mutations related with the development of nervous system,such as ARX,MECP2,usually associate with the prevalence of these syndromes.Gene mutations often disrupt synaptic plasticity,leading to protein adjusting spiral out of control,resulting in imbanlance of excitement and inhibition in brain,which develop a series of diseases.Mechanisms of early-life seizures and autism turn out to be in several levels,for gene mutations may lead to changes in both molecules and cells,resulting in intelligence and behavior abnormalities.Genetic research progress of syndromes with the comorbidity of epilepsy and autism are reviewed in this paper,in order to provide insight into their underlying pathophysiology and elucidate new therapeutic approaches of both conditions.

The defense mechinism of heat shock protein(HSP)acting as moleculars chaperons requires heat shock transcription factors as the primary mediators of the heat shock response.Increased expression of HSP may protect the heart.Overexpression of HSP can inhibit cardiomyocyte apoptosis,protect the integrity of the microtubules and the actin cytoskeleton in cardiac myocytes and endothelial cells exposed to ischemia,participate in the folding and activation of protein kinases and transcription factors such as HIF-1? and HSF1,bind to endothelial nitric oxide synthase(Enos) and stimulate its activity,and downregulate cytokine production.Hence,it is of benefit to efficiently elevate HSP expression in myocardium using pharmacological and/or gene therapy procedures without any adverse effect.

Mammalian target of rapamycin (mTOR) is a serine/threonine protein kinase that is centrally involved in the control of cell growth, proliferation, differentiation and cell cycle regulation. Recent studies have found that the mTOR pathway is complicated and the dysregulation of mTOR pathway is recognized to be associated with lots of tumors. Several inhibitors of mTOR could inhibit oncogene transformation, growth and angiogenesis of tumors. So far, four inhibitors of mTOR have been tested in clinical trials, and some have been accessed to phase Ⅱ or Ⅲ trial. Therefore, in this review, we discuss the regulators that govern mTOR pathway activity, and highlight clinical results obtained with the first generation of mTOR inhibitors to reach the oncology clinics.

Circulating tumor cell ( CTC ) testing is characterized by its invasiveness, sampling convenience and facility for real-time monitoring.The booming detection technologies based on physical or immunological features, as well as the subsequent molecular analysis of CTCs including subtype classification, single cell sequencing and in vitro culture, has greatly enriched our comprehension of CTCs and cancer heterogeneity.Meanwhile, a great of researches have demonstrated the significance of CTCs testing in the clinical practice of cancers involving aspects of early diagnosis, treatment monitoring and prognosis.

OBJECTIVE:To observe the clinical efficacy and safety of prucalopride in the treatment of functional constipation (FC). METHODS:In prospective self-controlled study,87 female patients with FC were selected and given prucalopride 2 mg,1 time per day. The total course was four weeks. The defecate frequency,stool property and constipation symptom grade were ob-served before and after treatment. Related adverse drug reaction were observed during treatment. RESULTS:During the period of treatment,the defecate frequency was gradually increased,the stool property was gradually improved,and the constipation symp-tom grade of the patients was also improved. The difference had statistical significance before and after treatment(P<0.01). No sig-nificant adverse drug reaction was found during the study. CONCLUSIONS:Prucalopride is a safe and effective treatment for pa-tients with FC.

Objective To investigate the role of protein O-linked N-acetyl-glucosamine (O-GlcNAc) modification in glutamine-induced improvement in the vascular hyporeactivity in rats with septic shock.Methods Thirty-two adult male Sprague-Dawley rats,aged 2-3 months,weighing 250-300 g,were randomly divided into 4 groups (n =8 each):sham operation group (S group); septic shock group (C group); glutamine group (G group) ; alloxan group (A group).Septic shock was induced by cecal ligation and puncture (CLP).In G and A groups,glutamine 0.75 g/kg was infused intravenously over 30 min at 1 h before CLP,and in addition alloxan 90 mg/kg was infused intraperitoneally in A group.Phenylephrine (PE) 0.5,1.0,2.0,and 2.5 μg/kg was injected intravenously at 20 min intervals at 6 h after CLP and the percentage increase in mean arterial pressure (MAP) was calculated.The thoracic aorta rings were isolated to perform the isolated vascular tension experiment.The concentration-response curve of PE was obtained in tension experiments,and the PE maximum efficacy (Emas) and median effective dose ( EC50 ) were calculated.The expression of O-GlcNAc modification and iNOS content in the thoracic aorta were detected in all groups.Blood samples were taken to determine the serum concentration of NO.Results Compared with S group,the percentage increase in MAP and Emax were significantly decreased,while the EC50,serum concentration of NO,and expression of O-GlcNAc modification and iNOS content in thoracic aorta were significantly increased in C,G and A groups ( P ＜ 0.05).Compared with C group,the expression of O-GlcNAc modification in the thoracic aorta was significantly increased,and EC50 was significantly decreased in G group,and the percentage increase in MAP and Emax were significantly increased,while the serum concentration of NO,and content of iNOS in the thoracic aorta were significantly decreased in G and A groups ( P ＜ 0.05).Compared with G group,the EC50,serum concentration of NO,and content of iNOS in the thoracic aorta were significantly increased,while the percentage increase in MAP,Emax and expression of O-GlcNAc modification in the thoracic aorta were significantly decreased ( P ＜ 0.05 ).Conclusion Glutamine improves the vascular hyporeactivity through increasing the level of protein O-GlcNAc modification in rats with septic shock.

Objective To observe the hypoglycemic, hypolipidemic and antioxidant effects of Zhuye Shigao Decoction (ZSD) on experimental type 2 diabetes mellitus rats. Methods Type 2 diabetes mellitus rat model was induced by intragastric administration of high fat diet(10 mL/kg) and intraperitoneal administration of streptozotocin (30 mg·kg-1). Sixty male Sprague-Dawley rats were randomized into normal group, model group, low-, moderate-and high-dose ZSD groups (in the dosage of 3.6, 7.2, 14.4 g·kg-1·d-1 respectively), and Metformin group (0.15 g·kg-1·d-1) , 10 rats in each group. With fasting blood glucose, urine glucose, glycosylated hemoglobin, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol(LDL-C), serum insulin, serum superoxide dismutase(SOD) and malondialdehyde (MDA) as the main indexes, we evaluated the influence of ZSD on the blood glucose and lipid levels as well as oxidative stress in type 2 diabetes mellitus rats. Results Compared with the model group, the levels of blood glucose, urine glucose and glycosylated hemoglobin, and the contents of TC, TG, MDA were decreased (P <0.05), whereas SOD activity and serum insulin level were obviously increased (P < 0.05) in ZSD groups. ZSD showed dose-related effectiveness in the treatment of diabetic rats. Conclusion ZSD has certain hypoglycemic, hypolipidemic and antioxidant effects in treating type 2 diabetes mellitus.
