AIM: To evaluate the efficacy and safety of orbital decompression in the treatment of Graves ophthalmopathy. ·METHODS: Totally 55 patients 77 eyes with Graves eye disease were selected in our hospital from February 2011 to February 2016. All eyes underwent orbital decompression, the visual acuity, exophthalmos and complications of the patients were followed up for 6mo. · RESULTS: Postoperatively 6mo, the best corrected visual acuity were 0. 23±0. 09, which were better than that of preoperative 0. 46±0. 07(P<0. 05). Postoperatively 6mo, the degree of exophthalmos of the patients were 16. 20 ± 1. 99mm, which was significantly lower than that preoperative 20. 13±1. 87mm (P<0. 05). Postoperative CAS score was ≤3 points in 56 eyes ( 73%) , significantly increased compared with preoperative 15 eyes (19%), the difference was statistically significant (P<0. 05). There were 50 eyes ( 65%) with color vision disorder before operation;after operation, 42 eyes (55%) had significant improvement in visual impairment, and there was no change in the eye in 8 eyes (10%). Postoperatively 6mo, the average decreased degree of exophthalmos were 3. 87±1. 03mm;5 cases were found postoperative diplopia, new diplopia rate was 10%;followed up for 3mo, diplopia disappeared. ·CONCLUSION:Orbital decompression is an effective method for the treatment of Graves ophthalmopathy, but attention should be paid to postoperative complications such as diplopia.

Objective To investigate insulin resistance and the effect of physical training on it in the pa- tients with chronic heart failure (CHF). Methods One hundred and twenty NYHAⅡ-ⅢCHF patients were ran- domly divided into a training group( n = 65 ) and a routine therapy group (n = 55 ). Another 35 healthy subjects were recruited as control group. All the patients were treated with routine anti-CHF drugs, and the training group patients had received physical training twice a day in addition. The HOMA-IR, insulin sensitivity index (ISI) , left ventricu- lar ejection fraction (LEVF), left ventricular fractional shortening( LVFS), 6-minute walking distance, heart rate and mean blood pressure were compared between the training and routine therapy groups before and after physical ex- ercise in both groups, and a comparison was made between the patients and the controls before the intervention with regard to HOMA-IR and ISI. Results Comparing with control group, ISI was reduced while the HOMA-IR in- creased (P

0.05). After dividing the patients into early-onset and late-onset subgroups, there were significant differences of DRD4 genotype and allele frequency between early-onset patients and controls (P0.05). Conclusion The results suggested that the polymorphism of DRD4 receptor gene may be associated with early-onset OCD. The 3/4 genetype may be the risk factor of early-onset OCD. Early-onset and late-onset OCD may have different etiology.

OBJECTIVE To evaluate the use of antibiotics after coronary artery bypass.METHODS Forty patients were assigned into two groups,vancomycin group and cefradine group.Each included 20 patients.We compared the infection cases,cost of hospitalization,and cost of medicine after CABG.RESULTS There were no difference of(infection) between two groups,the cost of hospitalization was fewer in cefradine group.(CONCLUSIONS) The short-term use of cefradine after CABG could achieve the goals of preventing infection of CABG,and save medical resources.

Objective To analyze the reasons and treatment measures of cerebral infarction following operation of hypertensive cerebral hemorrhage. Methods Sixty-one patients with cerebral infarction following operation of hypertensive cerebral hemorrhage were retrospectively analyzed. Results The outcome was evaluated on basis of activities of daily lives (ADL): Ⅰ 10 cases, Ⅱ 11 cases, Ⅲ 14 cases, Ⅳ 8 cases, Ⅴ3 cases and death 12 cases. Conclusions The occurrence of cerebral infarction following operation hypertensive cerebral hemorrhage is associated with degree of the hemorrhage compression, vasospasm, hypertension,operative skill and postoperative management. The early operation, improved operative skill and hyperbaric oxygenation are the important factors for the prophylaxis and treatment of cerebral infarction.

Objective To evaluate the protective effect of aminophylline on myocardium in the patients undergoing prothetic valve replacement operation of heart.Mothods Thirty patients undergoing prothetic valve replacement operation of heart were randomized to be treated either with aminophylline(n=15)or without aminophylline treatment(n=15). Aminophylline(5mg/kg)was injected intravenously at 15 minutes after induction of anesthesia.Cardiac troponin I(cTnI), cyclic adenosine monophosphate(cAMP),myeloperoxidase(MPO),ratio of aortic blood neutrophil count to coronary vein sinus blood neutrophil count,hemodynamics,time of aortic cress-clamping and other clinical data were recorded during the operation.Results There were no differences between the two groups in the major perioperative variables.Plasm cTnI concentration in both groups increased after off-clamping than that before CPB,however,it was lower in aminophylline group than that in control group.Concentration of cAMP in both groups after off-clamping was lower than that before CPB, however cAMP concentration in aminophylline group after off-clamping was higher than that in control group.Myocardial MPO activity and neutrophil count ratio after aortic off-clamping in aminophylline group was significantly lower than that in control group.Conclusion These results suggest that aminophylline is helpful to unprotection of myocardial and decreases the sequestration of neutrophil in myocardium.The mechanism of the protection may be related to the cAMP increased in myocardium.

Objective To introduce an improved method for collecting the blood of rat by cardiac puncture .Methods The study se-lected 90 Wistar rats,half male and half female ,and then the rats were anesthetized by intraperitoneally injecting 10％chloral hydrate solution according to 0.3 mL/kg body weight.Then using three-line positioning method to determine the puncture site ,the blood collection needle and blood collection tube were used to collecting the blood ,Finally,the blood volume of each rat was recorded .Results The success rate was cal-culated according to the single blood collection of 5 mL or more,and our 90 rats were collected 90 times,the success rate was about 82.2％. After centrifugation,the total serum was about 260 mL,the average serum separation of each rat was about 2.8 mL.Conclusion The im-proved positioning method of heart blood collection is intuitive and easy to learn ,and the total volume and quality of blood is high ,besides ,the new method has a small surgical trauma and a high efficiency ,which is worth to extend .

Background Qiang minority is minority groups of China with the special habits and customs and living condition. So whether the spectrum of disease and bacteria spectrum in conjunctiva are similar with Han nationality is worth paying attention. Objective Present survey was to obtain the data about bacterial species in conjunctival sac in Qiang minority population with the age 40 years old and more and the compare with matched Han nationality population. Methods This survey study was performed as the standardized training and protocol. A total of 212 eyes of 106 individuals from Qiang minority in Beichuan county and 640 eyes of 320 subjects from Han nationality in Mianyang city received questionnaire survey and ophthalmological examination. The secretion of the inferior palpebral conjunctival sac was embrocated and inoculated on blood plate for 48-72 hours. The bacteria was separated and identified. This study was approved by the Ethic Committee of Sichuan Provicial People' s Hospital. Orally informed consent was obtained before the medical procedure. Results All the examinee finished the survey and examination with a good compliance. No significant difference was found in the demography between these two groups of population. The multiple bacterial positive rate in conjunctival sac was 59. 4% in Qiang minority and that of Han people was 66. 3% with a considerably difference between them (χ2 = 2. 27,P = 0. 13). The multiple bacterial species were simultaneously detected in 26.2% in Qiang minority population and 11.88% Han people, showing evidently difference (χ2 = 106. 40, P = 0. 00 ) . The positive rate of corynbaccterium in conjunctival sac of Qiang minority was statistically lower than that of Han people (20. 7% versus 45. 0% ,χ2 =31. 75 ,P = 0. 00) ,but there was no statistical difference in the positive rate of staphylococcus epidemics between two groups (χ2 = 1. 89 ,P = 0. 17). Conclusion The bacteria positive rate in conjunctiva sac is resemble in the population over 40 years in both the Qiang minority and Han nationality. The simple bacterial species is found in majority people in two groups of subjects. The positive rate of multiple bacterial strains coexistence is more in the Qiang minority. The bacterial strains is different between Qiang minority and Han nationality.
