In order to increase the underachievement students’ score,we investigate their way of learning by questionnaire and interview. We find that learning motivation,learning style,learning time and thinking ability are the most important factors. So the underachievement students can be divided into four classes: learning motivation insufficiency, learning method incorrectness, learning time insufficiency and thinking ability insufficiency. And we raise some education strategies for each class.

For promoting the quality evaluation of Gardenia resource,a UPLC method for the determination of 4 compounds (geniposidic acid,geniposide,crocin-1 and crocin-2) in Gardeniae Fructus was established.The UPLC separation was performed on an Waters Acquity UPLC BEH-C18 (2.1 mm× 100 mm,1.7 μm) column eluted with the mobile phases of acetonitrile-0.1％ formic acid solution in a gradient mode at a flow rate of 0.3 mL· min-1.The detection wavelengths were 240 nm and 440 nm,respectively.Under the optimum conditions,the calibration curves of four analysis were linear in the range of 0.0065-0.0096 μg· mL-1,with correlation coefficients more than 0.9995.The limits of detection (LODs) of four analysis were in the range of 0.0386-0.1875 μg· mL-1.As the results of determination of 4 compounds of 12 batches of Gardeniae Fructus showed,there was great differences between the contents of the 4 compounds,the contents of geniposide were 2.44％-6.96％,while the contents of crocin-1 were 1.26％-3.04％.In addition,fingerprints of 12 batches of Gardenia resources were built using ChemPattern software,and analysis and exploration over the detection results of several samples were carried out using multivariate statistical method (similarity analysis,principal component analysis and cluster analysis).The present study provided a reference to value the importance of this method in the quality evaluation and quality control of Gardeniae resources and slices.

(2) MRA imaging characteristics and infarct pattern: 29 cases ( 82.9％ ) of patients with stenosis or occlusion showed moderate severe stenosis,6 cases( 17.1％ ) showed MCA occlusion. 30 cases( 85.7％ ) showed ischemic infarction,in which perforating artery infarction was the most common infarct pattern of middle cerebral artery stenosis or occlusive patients( 53.3％ ) ,followed by water-shed infarct ( 26. 7) ％, pial infarct was ielatively small (20. 0％ ). ConclusionThe hemiplegia was the most common clinical symptoms in patients with MCA stenosis and occlusion, and mainly involves to the face,upper and lower limb;The perforating artery infarction was the most common infarct pattern,and its infarct mechanism was an artery-to-artery embolism or hemodynamic abnormalities.

?AlM: To evaluate the long - term effects of laser peripheral iridectomy ( LPl ) and trabeculectomy in treating early chronic angle-closure glaucoma.
?METHODS: Ninety-eight patients (102 eyes) with early chronic primary angle-closure glaucoma were randomly divided into two groups. Group A of 50 patients (54 eyes) was treated with LPl and group B of 48 patients (48 eyes) with trabeculectomy. After 3 - 8y of follow - up observation, comparison would be made from the perspectives of postoperative eyesight, intraocular pressure, anterior chamber angle, visual field and cup/disc ratio ( C/D) .
?RESULTS:ln group A, 24 eyes with eyesight declining, 22 eyes with theintraocular pressure>21mmHg (1mmHg=0. 133kPa), 21 eyes with chamber angle synechia >180o, 21 eyes with visual field narrowed, 21 eyes with C/D ratio enlarged. The results of group B for the same items were 10, 5, 4, 4, 4 eyes respectively. The comparative difference was statistically significant (P<0. 05).
?CONCLUSlON:Good effects will be achieved for early-stage chronic angle - closure glaucoma with surgical method. Trabeculectomy is obviously better than LPl for the long-term effects.

Objective: To observe the effect of electroacupuncture (EA) on serum interleukin (IL)-6, IL-8 and IL-10 in rat models of cerebral ischemia-reperfusion, and to discover the mechanism of EA in preventing and treating cerebral ischemia.
Methods:Male Sprague Dawley (SD) rats were randomized into a sham-operation (SO) group, a model control (MC) group, and an EA group, which were sub-grouped into a 6-hour group and a 24-hour group. In the SO group, rats only received vessel separation with filament placed inside without any treatment. In the MC and EA groups, the focal cerebral ischemia-reperfusion model was induced by using modified Longa method with intraluminal filament. The MC group didn’t receive any treatment;the EA group received EA at Baihui (GV 20) and Dazhui (GV 14) with sparse-dense wave for 30 min. The levels of serum IL-6, IL-8 and IL-10 were detected by using Elisa test.
Results: Six hours after ischemia-reperfusion injury, the levels of serum IL-6, IL-8 and IL-10 in the MC group were significantly higher than those in the SO group (P<0.01, P<0.05, P<0.05);the level of serum IL-8 in the EA group was significantly lower than that in the MC group (P<0.05), while there were no significant differences in comparing IL-6 and IL-10 between the EA group and the MC group. Twenty-four hours after ischemia-reperfusion injury, the levels of serum IL-6 and IL-8 in the EA group were significantly lower than those in the MC group (both P<0.05), while there were no significant differences in comparing the level of IL-10 among the three groups.
Conclusion:Early intervention by EA can regulate the levels of serum IL-6 and IL-8 in cerebral ischemic injury.

OBJECTIVETo observe the clinical effect of anatomic shape bracket splints designed by 3D-MAX software.

METHODSHealthy adult volunteers' forearms and wrist data were measured and processed by 3D-MAX software. Then we designed and made anatomic shape bracket splints. Totally 60 distal radial fracture patients were equally assigned to the test group and the control group. After manual reduction, patients in the test group used anatomic shape bracket splints, while those in the control group used common splints. The palmar dip angle, ulnar fleet angle, and radius height of standard X-ray in normal and lateral positions were measured after treatment, at 1, 3, and 6 week after treatment, respectively. Meanwhile, the incidence of complications was recorded during the whole treatment process.

RESULTSCompared with the control group, the palmar dip angle and ulnar fleet angle were larger in the test group after one week of treatment (P < 0.05). The radius height of the treatment group was higher after one, three, and six weeks of treatment (P < 0.05). Compared with the control group, the incidence of complications was obviously less in the test group (P < 0.05).

CONCLUSIONSAnatomic shape bracket splints designed by 3D-MAX software fit local anatomic features and need no more shaping. Its easier use with lesser complications could maintain the stability of bone fracture better.

Objective To observe the effects of grape seed proanthocyanidin extract (GSPE)combined with atorvastatin on carotid atherosclerosis of the elderly. Methods Consecutivly 122 patient aged( 73.2 ±12.8) years with hypercholesterolemia and diagnosed as asymptomatic carotid artery plaques were randomly assigned to single atorvastatin(20 mg/d) treatment group (n=63) and combination treatment (atorvastatin 10 mg/d plus GSPE 400 mg/d) group (n=59).Serum total cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) and high-sensitive C-reactive protein (hs-CRP) levels were detected before treatment and 3,6,12 months after treatment.Mean maximum carotid intima-media thickness (CIMT),plaque score and stability were also assessed by carotid ultrasound. Results After 3 months of treatment,serum levels of TC,TG and LDL-C in both groups were lower than before treatment (all P＜0.01),but no difference was found between the two groups (P＞0.05).HDL-C levels was enhanced by 20.2％ in combination treatment group after 3 months of treatment (P＜0.05),there was difference after 6 months treatment between two groups (P＜0.05).Serum hs-CRP concentrations were decreased by 1.7 mg/L and 3.6 mg/L,3.8 mg/L and 6.3 mg/L,5.9 mg/L and 8.3 mg/L after 3,6 and 12 months treatment as compared with pretreatment,respectively in the two groups (P＜0.05 or P＜0.01).There was difference in hs-CRP levels between groups after 6 and 1.2months of treatment (P＜0.05 or P＜0.01).There were MMCIMT reduction by 1.3％ and 2.0％ (P＞0.05),3.4％ and 5.3％(P＞0.05 and P＜0.05 ),5.1％ and 8.6％ after 3,6 and 12 months of treatment(P＜0.05 and P＜0.01) in the two groups,with distinct difference after 12 month treatment (P＜ 0.01 ).The plaque scores were declined by 6.8 ％ and 13.1％ ( both P ＞ 0.05 ),14.5 ％ and 28.0％ (P＞0.05 and P＜0.05),19.2％ and 45.0％(P＜0.05 and P＜0.01)after 3,6 and 12 months of treatment while significant difference was found between the two groups after 12 months treatment (P＜0.05).Unstable plaque and the total number of plaque was dropped by 8 and 14 in single group,19 and 28 in combination group,respectively,after 12 months of treatment. Conclusions GSPE combined with atorvastatin may inhibit the development of carotid intima-media thickness,reduce carotid plaque and promote stabilization of carotid plaque.
