Objective To determine whether an environmental intervention tailored to each patient's allergic sensitization and environmental risk factors could improve asthma-related outcomes. Methods Irritant or allergen sensitivity determined by the patient's exposure history and confirmed with skin test. Patients were asked to record 2-week days without symptoms, days off-work(or school) and ?2-agonist puffs. Pulmonary function was also examined. Ninety-six asthmatics with atopic asthma (aged 16-78 years) were randomly assigned to a control group, an intervention group that received an educational handout monthly for 2 months. Asthmatics of both groups inhalded budesonide at a daily dose 200-800 ?g and ?2-agonist as needed. Environmental intervention lasted six months and included education and remediation for exposure to allergens. The control group had no special recommendations. Results The intervention group had more days without symptoms compared with the control group (13.4 vs.10.1days, P

Objective To explore the incidence and risk factors of anti-tuberculosis (TB) drugs induced liver injury (ATDILI) and to discuss its impact on the treatment outcome of patients treated with first line anti-TB drugs.Methods Among the patients who received anti-TB treatment with directly-observed treatment strategy (DOTS),121 patients with ATDILI and 817 patients without ATDILI were included in this retrospective cohort study.Binary Logistic regression model was used to analyze the risk factors of ATDILI in univariate and multivariate analysis.The x2 test was used to compare the treatment success rates and drug resistant rates.Kaplan-Meier analysis and Log-rank test were used to compare the sputum smear/culture conversion rates and cavity closure rates.Results The incidence of ATDILI was 12.9％ (121/938) in this cohort.Multivariate Logistic regression showed that hepatitis B virus carrier with both hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) positive (OR=4.29,95％CI:2.15-8.58,P＜0.01),complicated with systemic lupus erythematosus (OR=3.34,95％CI:1.46-7.63,P=0.004),serum albumin ≤25 g/L (OR=3.14,95％CI:1.50-6.58,P=0.002) and alcoholism (OR=1.79,95％CI:1.14-2.82,P=0.012) were independent risk factors of ATDILI.The treatment failure rate in patients with ATDILI was significantly higher than that in patients without ATDILI (19.1％[24/121] vs8.0％[65/817],OR=2.86,95％CI:1.71-4.78,P＜0.01).The drug resistant rates of two groups were not significant different (4.1％[5/121] vs 1.7％[14/817],P＞0.05).The sputum smear/culture conversion rate (85.4％[41/48] vs 94.0％ [298/317],x2 =38.912,P＜0.01) and cavity closure rate (84.6％[22/26] vs 93.0％[198/213],x2 =20.709,P＜0.01) in patients with ATDILI were both significantly lower than those in patients without ATDILI.Conclusions The incidence of ATDILI is relatively high in hospitalized patients treated with first line anti-TB drugs.ATDILI has negative effects on treatment outcome of TB patient.Hepatitis B carrier with positive HBsAg and HBeAg,systemic lupus erythematosus,albumin ≤25 g/L and alcoholism may increase the risk of developing ATDILI.

OBJECTIVETo compare clinical effects between percutaneous compressing plating (PCCP) and proximal femoral nail antirotation (PFNA) for the treatment of patients with intertrochanteric fracture with risk external wall.

METHODSFrom September 2007 to June 2010, 43 patients with intertrochanteric fracture with risk external wall were treated by PCCP or PFNA according to different kinds of internal fixations. There were 22 cases in PCCP, including 9 males and 13 females with an average age of 68.4 (ranged, 60 to 86) years old, and 13 cases with type A2.2 and 9 cases with type A2.3; while 21 cases in PFNA, including 7 males and 14 females with an average age of 67.7 (ranged, 57 to 93) years old, and 10 cases with type A2.2 and 11 cases with type A2.3. Blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up were observed and compared.

RESULTSAll patients were followed up for 12 to 22 (means 18.4) months, and all patients were obtained fracture healing, and recovered walking ability as before injury. There were no significant differences in blood loss, operation time, hospital stay, fracture healing time, complications and Harris score after 1 years' following-up (P>0.05). One case occurred displacement on the top of greater trochanter, and 1 case injuried weakness of hip abduction. One case occurred screw breakage in PCCP, while 1 case occurred hip joint pain in PFNA.

CONCLUSIONBoth of PCCP and PFNA in treating patients with intertrochanteric fracture with risk external wall can receive good clinical effects, while the effects and therapy strategy for displacement of bone on the top of lateral wall should further study.

For the high cost and mobility issues, a home uterine contraction pressure monitoring system based on Windows CE platform was developed. In this paper, the design of hardware circuit, micro-controller system and LabVIEW program based on Windows CE are discussed. The clinical validation experiment in hospital for this system was made and the experimental results show that this system complies with the trend that current medical equipment is becoming portable, homely and networked. Through real-time monitoring uterine contraction pressure, occurrence of premature birth and abortion can be prevented effectively.

Objective To optimize the extraction technology of perilla seeds oil from the oil cake of perilla seeds (OCPS) by using the contents of active fatty acids as evaluation standard. Methods The fatty acids were extracted from OCPS,the residue of perilla seeds after cold-press, by smashing tissue extraction (STE), the new technology selected through comparing with classical leaching extraction (LE), Soxhlet extraction (SE), ultrasonic extraction (UE), and supercritical-CO2 fluid extraction (SFE). For optimized condition of STE, orthogonal test was designed and completed. The contents of five fatty acids in extracted oil and OCPS were determined by GC. Results The optimized extraction parameters were smashing for 1.5 min under extraction power of 150 W and 1:6 of the material/solvent ratio. The contents of five fatty acids in the oils extracted by five techniques from OCPS and determined by GC were as follows:a-linolenic acid (41.12%-51.81%), linoleic acid (15.38%-16.43%), oleic acid (18.93%-27.28010), stearic acid (2.56%-4.01%), and palmitic acid (7.38%-10.77%). Conclusion The results show that STE is the most efficient technology with the highest yield (LE:0.57%; SE:1.03%; UE:0.61%; SFE:0.8(r; STE:1.17%) and shortest time (LE:720 min; SE:360 min; UE:30 min; SFE:120 min; STE:1.5 min) among five tested extraction technologies. It is fast reported using STE to extract herbal oil enriched with active fatty acids.

To assess the impact of the operational simulation training system on the cultivation of ophthalmic students.
●METHODS: Four hundred and eighty ophthalmic students in China Medical University from 2009 to 2011 were chosen as objects and divided into two groups at random. The students in the experimental group used operation simulation training system combined with traditional teaching methods, while the students in the control group only used traditional teaching methods. We examined the operation skills and the confidence of all the students half a year later.
●RESULTS: The improvement of the operation skills during the suture technique examination, and the confidence for operation technology were significantly different in two groups. The basic skills of the students in the examination groups improved apparently during the operational simulation training and they were full of confidence to their operational technique.
●CONCLUSlON: The operational simulation training is useful for promoting the clinical ability for ophthalmic students and should be widely popularized.
