Firstly the paper expounds the fact that letting patients pick their doctors goes with the tide of social development: ①the connotation of medical quality determines the necessity of patients involvement; ②evaluation of medical quality has extended from self appraisal to social assessment; and ③the mechanism of letting patients pick their doctors conforms to the medical quality requirements of the times. Then the paper discusses the positive impact of letting patients pick their doctors on medical quality, including the choice of doctors by outpatients and the impossibility of doing so in medico technical and emergency departments or by inpatients. The paper also gives an account of the measures taken for safeguarding medical quality when adopting the practice of letting patients pick their doctors. Lastly the paper explains the boosting role of the practice and the difference between letting patients pick their doctors and letting them name particular surgeons for their operations.

Methods One hundred and fourty cases of moderate and severe asthmatic children were treated in non- acute period aged from 4 to 14 years by inhaling salmeterol xinafoate and fluticasone propionate powder, compared with control group treated by flu-ticasone propionate in 106 cases, and the pulmonary function was monitored simultaneously. Results The total effective rate of the treatment group and control group were 99. 3 % , 99. 1 % , respectively.The pulmonary function indexes such as the first one second expiration volume(FEV1), flow velocity of 50 % expiration vital capacity(FEF50%), peak expiration velocity(PEF1) after being treated 4 months was improved significantly compared with those before treatment.The difference between them was statistically significant (P

OBJECTIVETo assess occlusal balance of normal occlusion in intercuspal position with maximal bite force.

METHODSMaximal bite force was recorded in intercuspal position by use of T-Scan II system from 123 subjects with normal intact dentitions. Occlusal balance of normal occlusion was quantitatively analyzed from center of force, percentage of bite force, and occlusal contacts.

RESULTSThe relative position of the center of bite force, the difference in bilateral force percentage, and unsymmetrical coefficient followed normal distributions. The 95% reference ranges for corresponding testing items were -6.60 to 6.68 mm, -15.50% to 12.10%, and 0.65 to 1.39. There was no statistic difference (P = 0.915) in occlusal contacts between left and right sides. The 98.4% of normal occlusion subjects had the center of bite force locating in posterior region of dentition when biting with maximal force in intercuspal position.

CONCLUSIONSOcclusal balance could be evaluated by T-Scan II system. Occlusion of normal subjects biting with maximal force was stable and bilaterally balanced in intercuspal position.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.

A new thermophilic fungus J18 isolated from the soil samples was identified as Paecilomyces thermophila. This strain produced effectively xylanase utilizing several lignocellulosic materials in the solid-state fermentation (SSF) , and wheat straw was the best carbon source. The results of single-factor-experiment showed that the wheat straw of particle size 0. 3 mm ~ 0.45 mm, initial moisture content of 83% , initial pH of 7. 0 and cultivation temperature of 50℃were the optimal conditions for xylanase production. Under the optimized conditions, it produced 18 580 U/g dry substrate after 8 days of cultivation. Therefore, xylanase production by Paecilomyces thermophila in SSF possess great potential for commercial applications.

Abstract?AlM:To investigate the choice of different treatments for malignant glaucoma.? METHODS: ln this retrospective case series, 21 malignant glaucoma patients ( 21 eyes ) admitted in Wuhan General Hospital of Guangzhou Military Command from May 2012 to May 2013 were analyzed. Sixteen eyes ( 76%) developed malignant glaucoma after filtration surgery, 3 eyes ( 14%) after EX - PRESS glaucoma filtration device, 2 eyes ( 10%) after glaucoma filtration Ahmed valve implantation. Main Outcome of corrected visual acuity, intraocular pressure ( lOP ) , anterior chamber depth and complications were detected.?RESULTS: lOP recovered by drug control in 13 eyes, anterior chamber depth. Four eyes were treated by vitreous water- bag aspiration combined with anterior chambers reconstructing. Two eyes were treated by cataract extraction and intraocular lens implantation. Two eyes were treated by posterior capsule excision combined with anterior vitrectomy. lOP before and after treatment was 29. 81±4. 98, 12. 71±3. 77mmHg, respectively (P=0. 00). Anterior chamber depth before and after treatment was 0.41± 0. 34, 2. 13 ± 0. 54mm, respectively (P = 0. 00). Corrected visual acuity before treatment was 0. 19 ± 0. 17, after treatment was 0. 20±0. 16 (P= 0. 36). Except for vitreous hemorrhage in 1 eye, there were no ocular or systemic adverse events observed in all patients.? CONCLUSlON: lt is good to diagnose malignant glaucoma in early period, and treated it step by step. For this can reduce lOP and restore anterior chamber.

AIM: To investigate the safety and effect of EX-PRESS glaucoma drainage device on open-angle glaucoma.
METHODS: A retrospective review of 40 patients ( 47 eyes ) whose eyes were diagnosed as open angle glaucoma through the best - corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , gonioscope, examination of the ocular fundus, and visual fields et al. Fourty patients 6-73y old ( mean 39. 90±16. 50y old) with the BCVA from 0. 01 to 0. 6 and the IOP from 18mmHg to 65mmHg were treated with EX-PRESS glaucoma drainage device after achieving not well IOP over three drugs. Follow - up of these patients 1d, 3d and 1wk after treatment, IOP, slit lamp examination were retrospectively observed. The changes of the BCVA, IOP were used to evaluate the safety and effect before and after treatmeat.
RESULTS: The mean BCVA was 0. 26 ± 0. 29 pre -operatively, while it was 0. 24±0. 22 after treatment one week. The mean BCVA decreased slightly, but there was no statistic difference between pre-treatment and post-treatment (t=1. 56,P=0. 13). The mean IOP was (36. 62 ±14.01)mmHg pre-operatively, (10.04±5.77)mmHg after treatment one day , ( 9. 59±4. 93 ) mmHg after treatment three days, (9. 47±3. 06)mmHg after treatment one week. The IOP was decreased significantly in post-treatment after one day, three days, one week compared with pre-treatment (F=157. 20, P<0. 05). Except for 5 eyes of the IOP below 5mmHg, there was no ocular or systemic adverse events observed in all patients.
CONCLUSION:EX-PRESS glaucoma drainage device is an effective and safe treatment for the patients with open-angle glaucoma. The risk and complication are low intraoperatively and postoperatively.
