ObjectiveTo observe the effect of amlodipine besylate combined with benazepril in treatment of old patients with primary hypertension and left ventricular hypertrophy,and analyze the safety.MethodsOne hundred and eight old patients with primary hypertension and left ventricular hypertrophy were divided into observation group(54 cases) and control group(54 cases) by random digits table.The patients in observation group were treated with amlodipine besylate combined with benazepril and the patients in control group were only treated with amlodipine besylate.The levels of blood pressure,interventricular septal thickness(IVST),left ventricular posterior wall (LVPW),left ventricular end-diastolic dimension (LVEDD) and left ventficular mass index(LVMI) before and after treatment for 6 months were measured and compared between two groups.The adverse effects after treatment were compared too.ResultsAfter treatment,the levels of 24hSBP,24hDBP,IVST,LVPW,LVEDD and LVMI were significantly decreased in both groups (P ＜ 0.05).Moreover,the levels of 24hSBP,24hDBP,IVST,LVPW,LVEDD and LVMI after treatment in observation group were significantly lower than those in control group(P ＜ 0.05).There was 1 case ( 1.9％ ) of dry cough,2 cases (3.7％) of mild ankle edema in observation group,while only 2 cases (3.7％) of mild ankle edema in control group.There was no significant difference in adverse effects between two groups (P ＞ 0.05).ConclusionsCompared with amlodipine besylate single treatment,amlodipine besylate combined with benazepril in treatment of old patients with primary hypertension and left ventricular hypertrophy can more effectively control blood pressure and reverse left ventricular hypertrophy.The adverse effects are not increased,which can be applied in clinic.

Ghrelin is involved in the process of feeding behavior and regulation of related energy metabolism,it also modulates the secretion of gonadotropins or transmitters concerning sex hormone releasing.It is considered as the factor connecting the HPG axis and energy metabolism.Body's nutrition has a bearing upon the process of reproductive system's onset and maturation.Adequate body weight is necessary for normal puberty onset.Obese children tend to have an earlier menarche.Ghrelin may pass on the information about nutrition to the hypothamalus in puberty onset.

Th17 is a CD4+ T cell subset that is a new member of Th1 and tH2.Recent studies have shown that it products IL-17A,IL-17F,IL-21 and IL-22,which play an imoortant role in rheumatoid arthritis.systemic lupus erythematosus,systemic sclerosis,inflammatory howel disease.autoimmune myocarditis and other autoimmune diseases.Deepen the understanding of Th17 and Th17 production in the advancement of autoimmune diseases will provide a new basis for future diagnosis.Th17 will become a new target for the treatment of human autoimmune diseases.

MicroRNAs (miRNAs) are a class of small single-stranded and non-coding RNAs that negatively regulate gene expression at the post-transcriptional level by degradation of target mRNA or inhibition of protein translation.Recent studies have shown that miRNAs play important roles in human diseases.It is of great importance to explore the role of miRNAs in the pathogenesis,early diagnosis and new therapeutic strategies of a variety of malignant tumors,including B-cell lymphoma.This review described the biosynthesis of miRNAs,the mechanisms of miRNAs target regulation and the involvement of miRNAs in the initiation and progression of human cancers,and summarized the role of miRNAs in B-cell lymphoma.

Objective To analyze the causes of falls in 107 patients, and to provide reference for the pre-vention of falls in hospitalized patients .Methods The analysis of hospitalized patients fall down where nursing area , age, fall time, place, disease, carer and the extent of internal medicine , brain and geriatrics is high incidence area of falls in the hospital , the ratio was 75.70%in total;the age of the fall patient ≥60 years old accounted for 81.31%;The high time for fall in the night (47.66%);Ward was the main falls area;Occurrence fall disease of fall patients mainly with cerebral infarction , hypertension, coronary heart disease , diabetes, accounted for 47.67%; In the fall with carer accounted for 71.96%;First grade damage accounted for 49.35%.Conclusion elderly people are the high risk group of falls , and the decline of physiological function and the influence of many diseases and drugs have a close relationship with fall .High time and place of falls in patients hospitalized in the night and ward , fall damage is given priority in mild and no damage , in fall patient with carer rate is higher .So the future hospital with fall preven-tion key points of nursing work should focus on pay close attention to the patient 's physiological status , disease and drug use, strengthen medical personnel to fall early risk assessment and give corresponding intervention measures , pay attention to the ward environment and the safety of facilities , strengthen the nursing management and nursing edu-cation, so as to reduce the occurrence of the event of a fall .

Objective: To introduce the advantages of approximate entropy (ApEn) in analyzing biological signals, to discuss the influences of time series' parameters on ApEn and elaborate the present conditions and prospects of its application on medicine. Methods: According to the definition and algorithm, ApEn has advantages on estimating the complexity of signal comparing with other non-linear analysis methods such as correlation dimension, fractal dimension, lyapunov index etc. Based on ApEn algorithm, we formulate programme to quantificationlly analyze the relationship between ApEn and each parameter of time series; Human EEG and ECG and other biological signals can reflect the state of the body. Through detecting changes of biological signals'ApEn, we can detect and monitor the state of an organization. Results: ApEn has many advantages such as a good anti-noise ability, the short date and so on. It makes up the defects of the correlation dimension ect. ApEn has nothing with the amplitude of time series. In the range of low-frequency, ApEn almost increases with frequency. When the date length is more than 1000 points, ApEn is stable. It quantificationlly describes that ApEn only requires short date. Recently. ApEn is widely used in diagnostics, monitoring, anesthesiology, and achieves good results. Conclusion: ApEn is a new developed non-linear analysis method which can estimate the complexity of the signal quantificationlly. It provides a new approach for diagnosing and monitoring a number of diseases. It has a wide application prospect.

Objective:To study the effect of hysteroscope electrotomy for treating infertile women with uterine septum.Methods: 64 patients with uterine septum were divided into observation group (25cases) and control group (39cases) according to different operation method. Patients of observation group received the combination mode of hysteroscope and laparoscope while the patients of control group received hysteroscope electrotomy. And thenthe effects of the two surgical methods for pregnancy outcome of the patients of the two groups were compared. Results: In 22 patients with complete uterine septum, the postoperative pregnancy rate was 59.09％ which was significantly higher than preoperative pregnancy rate (18.18％) (x2=4.539,P<0.05). The postoperative rate of normal childbirth in term was 31.82％ which was significantly higher than preoperative outcome (0％) (x2=8.324, P<0.004). In 42 patients which incomplete uterine septum, the postoperative pregnancy rate was 73.81％ which was significantly higher than preoperative pregnancy rate (33.33％) (x2=13,832,P<0.05). The postoperative rate of normal childbirth in term was 54.76％ which was significantly higher than preoperative outcome (0％)(x2=31.672, P<0.004).Conclusion: Hysteroscope electrotomy is significant in the treatment for patient with uterine septum, and it has series of advantages of minimally invasive surgery including small wound, less blooding, fast prognosis and others. Therefore, it is worthy in the clinical promoting.
