OBJECTIVE:To optimize the soxhlet extraction technology of Atractylodis macrocephalae,and to provide evi-dence for research and preparation of its formula granules. METHODS:Using the contents of atractylenolide Ⅰ,Ⅱ,Ⅲ as index, based on single factor test,the Soxhlet extraction technology of A. macrocephalae formula granules was optimized and verified by L9(34)orthogonal test with extraction time,solid-liquid ratio,extraction times as factors,and then compared with other technolo-gies (normal temperature extraction method,ultrasonic extraction method,reflux extraction method). RESULTS:The optimal ex-traction technology was as follows as 6-fold ethanol,extracting for 3 times,lasting for 8 h. Results of validation test showed that the extraction amounts of atractylenolide were 0.769,0.752,0.781 mg/g (RSD=1.99%,n=3) for 3 times,which were higher than the extraction amounts of other 3 methods(0.683,0.489,0.693 mg/g). CONCLUSIONS:The optimized extraction technolo-gy possesses high extraction rates of atractylenolide Ⅰ,Ⅱ,Ⅲ,and can be used for the extraction of internal ether from A. macro-cephalae formula granules.

AIM: to assess the effectiveness of a combined procedure ( pars plana vitrectomy with temporary keratoprosthesis, vitreoretinal surgery, and penetrating keratoplasty). in the complicated cases and the risk factors for the surgical failure.METHODS: Restrospectively reviewed charts of patients who underwent penetrating keratoplasty in combination with vitreoretinal surgery between 1990 and 2005, with a follow-up of 3mo to 9a. Analysis was focused on ocular history, indications for surgery, visual acuity (VA), anatomic results, and complications.RESULTS: 18 eyes had light perception or VA of hand motions only. The best-corrected VA improved during the first 3mo, increased in 72.2% of all eyes, remained unchanged in 27.78%, and no decreased. In 3 of 18 eyes (16.67%), VA was better than finger counting and hand motions, and nine eyes(50%) showed useful vision (0.05) postoperatively. 10 eyes showed a clear corneal graft (55.56%). 2 eyes needs the second keratoplasty, Bullous corneal edema was evident in 3 eyes, band keratopathy was evident in a 3 eyes. 10 patients were observed for more than 2a;6 had a clear graft (60%). Two eyes (11.11%) had silicone oil-corneal endothelium contact and all of these grafts failed.CONCLUSION: Although the functional outcome of a combined procedure is limited by primary and secondary tissue destruction, preserving ambulatory vision is possible and thus improves the quality of life, at least in patients with single remaining eyes.

Objective To investigate the cognition and attitude towards the elderly family nursing among nurses and college students in Chengde, and analyze its influencing factors. Methods A total of 1000 college students and nurses in Chengde were investigated by self-designed questionnaire about their cognition and attitude to elderly family nursing. Results Nurses' cognition and attitude towards the elderly family nursing was better than nursing college students, medical students were better than non-medical students; and there was no statistical significance about their expectation for government's senior citizen service among different groups. Conclusions More attention should be paid to family members' attitudetowards the elderly home care, and should strengthen the elderly family care through various way.

Objective To investigate the changes of serum bilirubin level in elderly patients with acute cerebral infarction and its significance.Methods 164 hospitalized elderly patients,who suffered from acute cerebral infarction within 1 week after onset,were divided into 2 groups according to age:group A aged over 60 years(n=85) and group B aged 40-60 years(n=79),and 66 healthy subjects aged over 40 years were collected as controls(group C).Serum bilirubin levels in all subjects were determined.The ratio of pulse pressure over mean arterial pressure(PP/MAP) in group A and B was calculated.Nerve function scores in the three groups were detected before and after 2 weeks of treatment.Meanwhile,the data of risk factors including blood glucose,blood pressure,blood lipids,smoking and drinking in group A and B were collected.Results Compared with group C,serum total,direct,indirect bilirubin levels were increased in group A and B(both P＜0.01),and the change was smaller in group A than in group B(P＜0.05).The nerve function scores was lower in group A than in group B before and after treatment [(35.2±12.6) vs.(44.3±7.9),(40.7±9.1) vs.(51.3± 4.1),t=5.58,9.73,both P＜0.01],but PP/MAP and the numbers of risk factors were higher in group A than in group B [(0.46±0.06) vs.(0.38±0.06),93.01 vs.71.20,both P＜0.01].There were no significant correlations of serum total,direct and indirect bilirubin levels with nerve function scores in group A or B(all P＞0.05).Conclusions Serum bilirubin level is increased in patients with acute cerebral infarction,but the endogenous antioxidant capacity is decreased because of aging,multiple risk factors and more serious atherosclerosis in elderly patients,and the increment of bilirubin level is relatively smaller in acute cerebral ischemia,leading to the reduced protective effect against stress.Serum bilirubin level may influence the prognosis in patients with acute cerebral infarction.

AIM: To evaluate the physiologic change of retinal thickness during pregnancy.
METHODS:Forty cases ( 80 eyes ) were included two groups:40 eyes ( 20 cases ) in healthy pregnant women group (including in the second and last trimester), and 40 eyes (20 cases) in healthy nonpregnant women group ( control group ) . The macular volume, average thickness, central subfield thickness and retinal thickness of other parafoveal areas were measured by optical coherence tomography scan.
RESULTS: The macular volume was 10. 06±0. 41mm3 and 9. 87±0. 30mm3 in healthy pregnant women group and control group respectively. The average thickness was 279. 43±10. 86μm and 274. 25±8. 07μm in healthy pregnant women group and control group respectively. The central subfield thickness was 235. 15±15. 05μm and 233. 00±15. 81μm in healthy pregnant women group and control group espectively. Statistically significant difference was found in macular volume and average thickness (P<0. 05). The retinal thickness of 8 parafoveal areas in healthy pregnant women group increased comparing with control group, but statistical significance was only found in superior-outer area and inferior-outer area(P<0. 05). OCT images of all cases were normal.
CONCLUSION:The macular retinal thickness increases during pregnancy in the second and last trimester. The physiologic change of retinal thickness should be considered when evaluating pathologic retinal disease of pregnant women.

Objective To study the changes of serum NO, TGF-β1, IL-10 and IL-17 Levels and study of the efficacy of Bismuth - containing quadruple and standard triple therapy for patients with Hp positive peptic ulcer. Methods 109 cases of peptic ulcer treated in our hospital were retrospectively selected, and Hp test was positive. According to different dosing regimen, the patients were divided into two groups. There were 54 patients in the control group, using standard triple therapy, and the regimen was lansoprazole, amoxicillin, and metronidazole. 55 patients in the study group were treated with bismuth-based western therapy with bismuth potassium citrate, rabeprazole, amoxicillin, and furazolidone. Two weeks after treatment were regarded as the observation period, and the levels of serum NO, TGF-β1, IL-10 and IL-17 in the two groups were compared before and after treatment. The effective rate of ulcer healing, Hp clearance rate and incidence of adverse reactions were compared. Results The level of serum NO, TGF-β1, IL-10 and IL-17 was significantly lower than that in the control group (P <0.05). The effective rates of ulcer healing and Hp clearance in the study group were significantly higher than those in the control group (P <0.05). There was no significant differences between the study group and the control group in the incidence of adverse reactions. Conclusion Western medicine with bismuth in the treatment of Hp peptic ulcer patients, the serum NO, TGF-β1, IL-10 and IL-17 levels of indicators have significantly improved, and has obvious advantages in clinical treatment, and it is a reasonable dosing regimen of high efficiency and low recurrence.

OBJECTIVE: The purpose of this study is to assess the effects of aging on air-conducted sound elicited cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential(oVEMP) in normal people. METHOD: Sixty normal subjects were recruited for the vestibular evoked myogenic potential examination. Among them, 20-40 year-old group was setted as the first group, 41-60 year-old group was setted as the second group, > 60-year-old group was setted as the third group. Each group included 20 normal subjects. SPSS 16.0 software was used to analyze the data. RESULT: As the age growing, P1 latency prolonged, N1-P1 amplitude decreased, and amplitude asymmetric ratio increased in cVEMP; N1 latency prolonged, P1-N1 amplitude decreased, and amplitude asymmetric ratio increased in oVEMP. CONCLUSION With the age growing, the time of otolithic organ input pathways prolonged, the function of otolithic organ decreased and the decrease level may be asymeetrical on both sides.
