Objective In recent years , SIT has gradually become the main way for the treatment of allergic rhinitis .To con-trast the clinical efficacy of specific immune therapy for one year and two years of allergic rhinitis and discuss the appropriate mainte -nance treatment time of subcutaneous immunotherapy with Dermatophagoides pteronyssinus . Methods Ninety-eight patients with al-lergic rhinitis to Dermatophagoides pteronyssinus were allocated to receive either treatment for one year (A group, n=46) or treatment for two years(B group, n=52).Nasal symptoms and medication scores of two groups were assessed to evaluate the clinical efficacy af -ter treatment respectively , and evaluate the quality of life of patients . Results There was no statistical significance in nasal symptom and medication scores between the two groups after one year treatment (7.00 ±1.08 vs 6.63 ±0.79, 1.50 ±0.51 vs 0.41 ±0.42, P>0.05).The quality of life in patients with decreased , but lack of statistical significance (345.00 ±31.89 vs 344.42 ±32.26, P>0.05).It presented statistical significance in nasal symptom and medication scores between the two groups after two years treatment (6.20 ±0.78 vs 4.29 ±0.64, 0.53 ±0.43 vs 0.21 ±0.34, P<0.05).The quality of life between patients also presented statistical significance (P<0.05). Conclusion Compared with A group, B group can significantly alleviate the symptoms of allergic rhinitis , so we think the optimal maintenance treatment time of specific immunotherapy for allergic rhinitis should be at least 2 years.

Objective To investigate the relationship between obesity parameters and obstructive sleep apnea-hypopnea syndrome (OSAHS) in aircrew. Methods A questionnaire survey in aircrew members was performed. Outcome measurement included body height, body weight, neck circumference ( NC), waist circumference (WC), and body mass index (BMI). Those with snoring during sleep and/or Epworth sleepiness scale (ESS)score ≥ 9 were screened with pulse oxygen saturation test during overnight sleep. Those with oxygen saturation decrease index ≥ 10 times/h and suspected OSAHS were tested by polysomnography (PSG). The objects were then assigned to three groups: the OSAHS group,the snore group and the normal group. The relationship between obesity parameters and OSAHS was analyzed. Results There were 399 ( 37. 54% ) overweight, 36 ( 3. 39% ) obesity, 130 ( 12. 23% ) increased NC, and 354 (33.30%)increased WC in 1063 aircrew members (OSAHS group ＞ snore group ＞ normal group; P＜O. 05). The mean value of BMI, NC and WC in the three groups were dittos. Multiple logistic regression analysis showed that overweight, obesity and increased WC were significantly associated with snoring (P ＜0.05) and snoring enlarged NC was significantly correlated with OSAHS (P＜ 0.05). Conclusion Increased BMI, NC and WC may be risk factors of OSAHS among aircrew. Effective prevention and treatment of OSAHS should be needed.

OBJECTIVE:To observe the effects of bisoprolol combined with conventional triple therapy on the efficacy and re-lated indexes of patients with rheumatic heart valvular disease (RVD) combined chronic heart failure. METHODS:110 patients with RVD combined with chronic heart failure were randomly divided into observation group(55 cases)and control group(55 cas-es). All patients were treated with oxygen inhalation,anti-infection,correcting electrolyte imbalance,controlling arrhythmia,and giving digitalis drugs and diuretic drugs(it can be disabled after edema symptom being controlled);based on it,control group was given Enalapril tablet with initial dose of 2.5 mg,once to twice a day,then adjusted to 10-20 mg after 1 week,twice a day+20 mg Spironolactone tablet,once a day+10 mg Propranolol tablet,once a day. Observation group was additionally given Bisoprolol fuma-rate tablet initial dose of 1.25 mg,once a day,and then increased to 10 mg based on condition improved and tolerability after a meal,once a day. They were treated for 12 weeks. Clinical efficacy,and LVEF,LVEDD,LVESD,SBP,DBP,HR before and af-ter treatment and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant (P<0.05). Before treatment,there were no significant differences in the LVEF,LVEDD,LVESD,SBP,DBP and HR between 2 groups(P>0.05). After treatment,LVEF in 2 groups were significantly higher than before,and observation group was higher than control group,LVEDD,LVESD,SBP, DBP and HR were significantly lower than before,and observation group was lower than control group,the differences were statis-tically significant(P<0.05). And there was no significant difference in the incidence of adverse reactions(P>0.05). CONCLU-SIONS:Based on conventional treatment,bisoprolol combined with conventional triple therapy shows good efficacy in the treat-ment of RVD combined chronic heart failure,it can improve cardiac function,with good safety.

Objectives To explore the effects of hemodialysis on oxidizing stress and plasma nitrogen monoxide (NO) levels in maintenance hemodialysis patients. Methods 67 maintenance hemodialysis patients (male 39, female 28, and mean age 58?13y) were enrolled in this study. Serum malondialdehyde (MDA) level was measured by colorimetry, and plasma NO level was determined by enzymatic method. The MDA and NO levels before and after hemodialysis were measured in 48 cases of the patients. Results After hemodialysis, the serum MDA levels significantly increased, and the plasma NO levels decreased. The patients with cardiovascular diseases had lower NO levels and higher MDA levels than the patients without ones before hemodialysis. The serum MDA levels of the patients using biological incompatible dialysis membrane increased after hemodialysis. Conclusion Hemodialysis treatment, especially using biological incompatible dialysis membrane increased oxidizing stress and decreased plasma NO levels in maintenance hemodialysis patients, and was significantly correlated with the pathogenesis of cardiovascular diseases.

Objective To research the surgical technique and curative effect of the posterior cruciate ligament(PCL) anatomical reconstruction with double-bundle hamstring tendons absorbable interference screw fixation via double-tunnel in femoral under arthroscopy. Methods 24 patients, average age of 32 years ranged from 17 to 42 years old, were treated with anatomical reconstruction of PCL through double-tunnel in femoral and one tunnel in tibia with double-bundle hamstring tendons fixed with absorbable interference screw under arthroscopic. The anterolateral bundle was reconstructed with multistranded autograft semitendinosus tendon grafts and was tightend and fixed, at knee flexion 15?-30?. The posteromedial bundle was reconstructed with multistranded autograft gracilis tendon grafts, and was tightened and fixed, at knee flexion 60?-70?. Results All the patients were followed up for a mean time of 9.4 months (6 months-19 months). All the knee joint motion were in normal range, no exhibition of pain and distinct trauma arthritis. The postoperative posterior drawer test, reverse Lachman test, tibia sags sign and reverse pivot shift test were all negative. The postoperative Lysholm score was (92.7?6.4) points, and the postoperative score increased significantly compared with the preoperative (t=3.12, P

Objective To further identify the isolated Mycoplasma genitalium (Mg) from the high risk population of STD in China. Mothods The morphology of Mg standard strains and clinical isolates were observed under electron microscopy (EM) and atomic force microscopy (AFM). Mg sample preparation for AFM was fixed on mica and AFM images of scanning observation were captured by contacting and tapping modes and operated under normal atmospheric pressure and temperature. Results and Conclusion Mg had a diversity of shapes, including flask, pear, spindle or round shape with projecting neck portion and slightly broadened terminal structure under EM. The morphologic features under AFM were similar to those observed by EM. The typical Mg showed shapes of flask and pear with noticeable narrow ring or mark in the neck portion. The size of Mg measured under EM and AFM was similar as well. Mycoplasma
