Inflammatory reaction plays an important role in the occurrence and development of ischemic stroke. Monocyte chemotactic protein-1 (MCP-1) is one of the subfamily members of the CC chemokine class. It can attract and activate a variety of cells, such as monocytes and T lymphocytes, promote the expression of cytokines, and participate in the occurrence of ischemic brain injury. This article reviews the progresses on the MCP-1 and ischemic stroke-related research.

Inflammatory bowel disease is a chronic non-specific intestinal tract inflammation,currently,its etiology and pathogenesis are not clear.The current conventional treatments include salicylic acid drugs, steroids, immunosuppressive agents, biological agents and surgery, but the prognosis is still not very optimistic.In recent years, a variety of other treatment options have emerged, such as anti-cytokine antibody, anti-chemokine antibodies.Clinicians pay more attention to treatment of inflammatory bowel disease.

Objective To understand the incidence and related risk factors of healthcare-associated infection(HAI)in neu-rological patients with cerebrovascular diseases.Methods The occurrence and risk factors of HAI in patients with cerebro-vascular diseases in a hospital between Jan and December 2013 were investigated and analyzed.Results Of 3 573 investiga-ted patients,214 had HAI,the incidence of HAI was 5.99%;the main infection site was respiratory tract (54.67%),fol-lowed by urinary tract (25.23%).Univariate analysis revealed that age,length of hospitalization,disturbance of conscious-ness,chronic obstructive pulmonary disease,diabetes mellitus,invasive procedures,application of antacids,and antimicro-bial prophylaxis were all related to the occurrence of HAI (P<0.05).Multivariate logistic regression analysis revealed that disturbance of consciousness,old age,invasive procedures,chronic obstructive pulmonary disease,and diabetes mellitus were independent risk factors for the occurrence of HAI (all P <0.05).Conclusion The incidence of HAI is high in hospitalized patients of the neurology department,there are multiple risk factors associated with HAI,it is necessary to take corresponding interventions for reducing the incidence of HAI.

Objective: To analyze the published domestic documents of the clinical trial for treatment of anal fissure in past 10 years, to evaluate the quality of literatures about anal fissure randomized controlled clinical trials, and to provide references of clinical studies for the treatments of anal fissure in Traditional Chinese Medicine (TCM). Methods: In term of principles of evidence-based medicine, we evaluate the published domestic literatures of the randomized controlled clinical trial for treatments of anal f issure in past 10 years. Results: We analyze 52 literatures which are in the method of randomized controlled clinical studies. 28 literatures (accounting for 53.85%) record diagnostic criteria, 38 literatures (accounting for 73.08%) make sure standards of evaluating the effect and 18 literatures (accounting for 34.62%) mention comparability between groups without describing the baseline statistics. Only 5 are marked as a funded research projects. Conclusion: in current published literatures of randomized controlled study for treatments of anal fi ssure, the problems are focused on: ① Experimental idea is unclear and design is unreasonable, ② The description of implemented process in randomized control is unspecif ic, ③ Signifi cant parameters in statistical data are missed and with less credibility, ④ Criteria of diagnosis and effi cacy are different, ⑤ Evaluation indicators are fuzzy. All above clue to the quality of clinical research needs to be improved rapidly, and standardized evaluation of eff icacy also needs to be created urgently.

Inflammatory bowel disease(IBD) is characterized by chronic non-specific inflammatory dis ease.The inflammation caused by abnormal immune response in intestinal mucosa exerts an important role in the pathogenesis of IBD.T helper 17 cells(Th17)are involved in the development of chronic inflammation and auto immune disease,whereas regulatory T cells can inhibit the function of autoimmune,and thus the balance of Th17/Treg balance plays an important role in intestinal homeostasis.Various strategies can be done to modulate Th17/Treg balance,such as antigen-presenting cells,microoganisms,some key molecules,natural compounds,proving a promising therapeutic method for IBD.

OBJECTIVE To evaluate the anti-vertigo effect of phencynonate hydrochloride. METHODS To detect the improvement of phencynonate hydrochloride on cerebral blood flow, a rat model wa s es?tablished with bilateral common carotid arteries occlusion. Phencynonate hydrochloride 0.1-4.0 mg·kg-1 was ig given, twice a day for three consecutive days and the alteration of cerebral blood flow was measured with laser Doppler flowmetry. Rotating acceleration equipment was used to provocate mouse vertigo for 30 min, and the spontaneous locomotor activities were tested for occurrence of vertigo in mice. Phencynonate hydrochloride 1.4-5.6 mg·kg-1 was ig given before rotating acceleration. Gastric phenol red emptying rate was used to determine the anti-nausea effect of the test drug in mice 30 min after phencynonate hydrochloride 1.4-8.4 mg·kg-1 was ig given. RESULTS The cerebral blood flow of the rat model with bilateral common carotid arteries occlusion was reduced significantly after 24 h (P<0.01). Compared with the model group, phencynonate hydrochloride (0.5, 2.0 and 4.0 mg · kg-1) increased the cerebral blood flow in a dose-dependent manner in rats with cerebral ischemia (P<0.01). The spontaneous locomotor activities were significantly reduced after vertigo stimulation in mice (P<0.05). Compared with the model group, phencynonate hydrochloride (2.8 and 5.6 mg · kg-1) increased the movement distance and speed of vertigo mice (P<0.05). Phencynonate hydrochloride (2.8, 5.6 and 8.4 mg·kg-1) inhibited the gastric emptying of mice (P<0.05). CONCLUSION Phecynonate hydrochloride can improve the cerebral blood flow and locomotor activities in vertigo rats, while inhibiting gastric emptying, which points to the therapeutic potential of phencynonate hydrochloride for vertigo in clinic.

Objective:To screen neuroses in medical students and explore related factors.Method:Totally 1677 college students were screened by Neuroses Screener,who was positive(scored 2 or more)was investigated with Questionnaire on History of Neuroses and interviewed by psychiatrist.Psychiatric diagnosis was made if necessary according to CCMD-2-R.EPQ,EMBU and Quality of Life Scale were applied to all subjects.Multi-factor analysis was made.Results:Negative life events,unhealthy parentai education and neuroticism in EPQ were main factors influencing the incidence of neurosis.EPQ-E and warmth from parents had protective effect on occurrence of neurosis.Conclusion:Neuroticism is the basis of neurosis,unhealthy parental education and negative life events precipitate the occurrence of neurosis.Exorcism and warmth of parents have protective effect.

Nowadays, lung cancer has become one of the most common malignant tumors. The animal models of lung cancer have played very important role in the research on the etiology, diagnosis and treatment of human lung cancers. According to the preparation method, the animal models of lung cancer can be divided into spontaneous, induced, transplanted and transgenic models. The transplanted animal models are most commonly used. Transplanted animal models can be classified into heterotopic transplantation model and orthotopic transplantation model, each has its own characteristics. This article aims to introduce the research progress of transplanted animal models of lung cancer in recent years, focusing on the establishment of animal model, the improvement of preparation of animal model, the application of imaging in vivo in evaluating the animal model, the use of transplanted animal model in the study of interventional therapy, etc.
