Objective To evaluate the effectiveness of allergen specific immunotherapy (SIT) in the treatment of allergic rhinitis. Methods A total of 132 patients with seasonal ragweed allergic rhinitis were enrolled in this study. The patients were randomly divided into two groups. SIT group, in which 68 patients were treated with ragweed SIT for six months before July for 3 years. ST (symptomatic therapy) group, in which 64 patients were treated with ST during seasonal symptomatic period. The healthy control group included 40 subjects. The levels of serum total IgE (tIgE), specific IgE (sIgE), ECP, IgG and IL-4, IL-5, IFN-? were measured, and eosinophil numbers were counted. The symptom score, lung-function test and skin prick test were performed before and after the treatment. Results The elevated levels of tIgE, ECP, IL-4, IL-5 in the sera and eosinophil counts in peripheral blood of the patients were significantly reduced, whereas the levels of IgG and IFN-? were increased following SIT. The levels of serum sIgE were not changed in both SIT and ST groups. 30.88% of the patients were clinically cured, the effective rate was 41.18%, the improvement rate was 20.59% after SIT, and only in 7.39% of patients there was no clinical improvement. In 16.18% of patients there were mild side effects to SIT. In the ST group, there was on change in all the laboratory results and clinical symptoms, and 25% of the patients developed asthma. Conclusion SIT was able to improve the symptoms and laboratory results of the patients with allergic rhinitis. The results indicated that SIT may be an effective and safe therapy for patients with allergic rhinitis.

Objective To observe the clinical efficacy of acupuncture-moxibustion in treating postsurgical gastroparesis syndrome (PGS) and the effect on gastrin (GAS) and motilin (MTL).Method Fifty PGS patients were randomized into a treatment group and a control group, 25 cases in each group. The control group was intervened by conventional medication, including effective gastrointestinal decompression, nutrition support, and psychotherapy; the treatment group was by acupuncture-moxibustion therapy in addition to the intervention given to the control group. The time of restoring gastric motility, the distention and fullness grading score, and serum GAS and MTL levels were observed, and the clinical efficacies were also compared.Result The total effective rate was 100.0% in the treatment group versus 92.0% in the control group, and the between-group difference was statistically insignificant (P>0.05). According to statistical analysis, there was a significant difference in comparing the time of restoring gastric motility between the two groups (P<0.01). The distention and fullness grading scores, GAS and MTL levels were significantly changed after intervention in both groups (P<0.01). The distention and fullness grading score, GAS and MTL levels of the treatment group were significantly different from that of the control group after intervention (P<0.01).Conclusion Acupuncture- moxibustion plus medication is an effective approach in treating PGS, and it can up-regulate the GAS and MTL levels.

Nowadays, various voice disorders are sprung out towards teachers of primary and secondary school, affecting their personal life and social work. Through literature review, the author aims at clearing up series of assessments and methods of voice training which are suitable for the teachers of primary and secondary school, such as establishing a right way of respiratory, phonation and resonance, avoiding occupational risk factors such as vocal abuse or misuse to regain healthy voice. Review of the several relevant literature and commentary about voice disorders of the teachers in primary and secondary school. Although various methods of voice training were reported from time to time to guide us SLP to carry out voice therapy, however, deviations of the clinical data from scholars' different points of view are waiting for our further support through case-control study.

OBJECTIVETo investigate the penile erectile function of hospitalized male patients with cardiovascular diseases, the incidence of erectile dysfunction (ED) in this cohort, and the relationship of ED with cardiovascular diseases and its risk factors.

METHODSUsing a self-designed questionnaire, we conducted an investigation among the hospitalized patients in the Department of Cardiovascular Diseases of the First and Second Affiliated Hospitals of Xi'an Jiaotong University. We measured their body height, body mass index (BMI), waist circumference, hip circumference, and blood pressure, obtained their personal data, past history, metabolic indexes, and erectile function scores by IIEF-5, and analyzed the risk factors of ED using univariate and multivariate logistic regression and OR analyses.

RESULTSTotally, 225 valid questionnaires were included in this investigation, which showed a 66.7% incidence of ED, 15.8% mild, 27.0% mild to moderate, 17.6% moderate, and 6.3% severe. The incident rates of ED in the 18-35 yr, 36-49 yr, 50-65 yr, and > 65 yr age groups were 13.6%, 39.1%, 89.2%, and 91.2%, respectively. Univariate logistic regression analysis manifested that the risk factors of ED in the patients with cardiovascular diseases included age (OR = 3.122, 95% CI 2.040-4.779), smoking (OR = 1.768, 95% CI 1.209-2.584), BMI (OR = 1.261, 95% CI 1.114-1.427), total cholesterol (OR = 1.77, 95% CI 1.339-2.340), TC/HDL (OR =1.715, 95% CI 1.349-2.181), hypertension (OR = 1.717, 95% CI 1.110-2.658), and coronary heart disease (OR = 2.235, 95% CI 1.169-4.275), while multivariate logistic regression analysis showed the risk factors to be age (OR = 4.99, 95% CI 2.264-10.998), financial condition, (OR = 2.804, 95% CI 1.127-6.976), smoking (OR = 2.109, 95% CI 1.179-3.772), BMI (OR = 1.414, 95% CI 1.136-1.760), and TC/HDL (OR = 2.001, 95% CI 1.016-3.943).

CONCLUSIONThe incidence of ED is high in hospitalized patients with cardiovascular diseases and rises with the increase of age. Age, smoking, financial condition, BMI, and TC/HDL are the risk factors of both ED and cardiovascular diseases, and financial condition is closely associated with ED.

This study is to investigate the influence and mechanism of action of asymmetrical dimethylarginine (ADMA) and the induced oxidative stress level on Alzheimer's disease (AD) incidence. ADMA concentration, nitric oxide, Abeta(40)/Abeta(42) ratio, inducible NO synthase (iNOS) activity and the concentrations of the induced free radicals including malondialdehyde (MDA), 3-nitrotyrosine (3-NT) and peroxynitrite (ONOO-) in the cerebrospinal fluid (CSF) from 34 neurologically normal controls and 37 AD patients were quantitatively determined and statistically compared. The results showed that the ADMA concentration significantly decreased in AD patients, and it showed negative correlation with the NO, iNOS activity, and showed positive correlation with MMSE score. ADMA concentration was negatively correlated with Abeta(40)/Abeta(42) ratio (P<0.01) with the observation that Abeta(40)/Abeta(42) ratio increased while ADMA level decreased in CSF in AD patients. The concentration levels of MDA, 3-NT and ROS significantly increased compared with the control with all the P values less than 0.05. These findings suggested that the ADMA disorder and the oxidative damage effect of the induced free radicals in CSF of AD patients are an important mechanism of AD incidence, and their joint regulation may provide new idea for the prevention and clinical treatment of AD.
