Objective To evaluate the hematologic effects of linezolid in advanced aged patients with hospital onset of infection.Methods The clinical characteristics and complete blood routine examination results of 45 elderly patients aged(92.9±5.2)years treated with linezolid over 600 mg of lowest dose everyday for more than 72 hours were retrospectively analyzed.Results Among the 45patients,20 patients(44.4％)had substantially lower platelet,6 patients(13.3％)lower haemoglobin,1 patient(2.2％)lower absolute neutrophil,and the linezolid treatment in 19 patients were discontinued due to hematological system adverse reactions.The significant drop in platelet occurred at(10.2±3.3)days after treatment.The significant drop in hemoglobin occurred at(9.8±3.0)d after treatment.The lowest count of platelet and hemoglobin took place at(13.1±3.9)d and (10.5±3.5)d after treatment,respectively.The drops in platelet and hemoglobin of some patients took place after cease of treatment.Stepwise logistic regression analysis revealed that treatment duration(OR =1.407,P＜0.05)and creatinine clearance rate(OR=0.732,P＜0.05)were the risk factors for thrombocytopenia.Conclusions The elderly patients using linezolid more likely suffer from adverse reactions of hematological system,particularly thrombocytopeniawhich is significantly more common in patients with renal insufficiency and prolongation of treatment time.The blood routine examination should be monitored closely when elderly patients are treated with linezolid.

Objective To evaluate the efficacy and safety of long-term nebulized corticosteroids and inhaled bronchodilators therapy on asthma in long term poor controlled elderly patients.Methods Prospective,randomized control study was conducted.63 elderly asthma patients,who received inhaled corticosteroids or combined with other long-term medication treatment for asthma control for more than 3 months but were still in moderate to severe persistent asthma state,were randomly divided into nebulizer treatment group (n=31) and dry powder inhalation group (n=32),and they were treated correspondingly with Budesonide inhalation suspension 1 mg and Salbutamol 2.5 mg BidorBudesonide/Formoterol powder 320/9 μg inhalation Bid.Patients in the two groups were evaluated for the differences in lung function,acute exacerbations of asthma,asthma control test (ACT) and adverse effects after 12-week treatment.Results The improvement in morning peak expiratory flow (PEF) and ACT score were better in the test group than in the control group [(29.2 ±14.4) ml vs.(15.8±13.5)ml,(4.8±2.2) vs.(3.0±2.7),t=3.715 and 2.897,P=0.000 and 0.005],but there were no statistical differences in average daily use of relievers and severe acute exacerbations between the test and control groups (t=1.512,P=0.136;x2=2.238,P=0.135).The local adverse effects caused by inhaled corticosteroids had no significant difference between the two groups.Conclusions Compared with the powder inhalation,the nebulizer inhalation administration of corticosteroids and bronchodilators could improve the asthma symptoms and lung function better in elderly patients with serious asthma condition and shows a good safety in tbe12 weeks of continuous treatment.

Objective To explore the clinical efficacy of the interventional recanalization for infertile women with fallopian tube obstruction. Methods 636 infertile patients with fallopian tube obstruction diagnosed by hystero-salpin-gngraphy were treated with interventional tubal recanalizafion under X-ray. Results Among 636 patients with 984 complete fallopian tubes obstruction,there were 804 recanalization in tile 984 fallopian tubes and the successful rate of recanalization was 81.71%. Among 252 fallopian tubes with not complete obstruction ,there were 252 recanali-zation in the 252 fallopian tubes and the successful rate of recanalization was 100%. The all successful rate of reca-nalization was 88.3%. These patients pregnancy rate was 28.30% in one year and the second fallopian tube obstruc-tion rate was 6.79%. There was 4 ectopic pregnancy. Conclusions Interventional tubal recanalization has important application in the diagnosis and treatment for infertile women with fallopian tube obstruction, h has merit, such as simple, safe and good effect.

OBJECTIVE:To study the mechanism and location of absorption of DZ18.METHODS:In this study,improved intestinal absorption experiments(in vivo,in vitro)were used to study the absorption of DZ18in rats.RESULTS:It was found that there was no significant difference in absorptive rate in rats between without and with bile duct ligation.The cumulative percentages of absorption were59.2%and58.8%.CONCLUSION:There are no significant differences among the absorptive rates at different parts of small intestine in rats,which shows that there is no specificity of intestinal segments in absorption.

OBJECTIVE:To establish the quality standard of Yanyan pills.METHODS: The constituents such as Lysimachia christinae,Radix et Rhizoma Glycyrrhizae and Radix Astragali were identified qualitatively by TLC,and the content of caffeotannic acid in L.christinae was determined by HPLC.RESULTS: The TLC spots were distinctive and well-isolated.The linear range of caffeotannic acid was 0.036～0.18 ?g(r=0.999 9)with an average recovery of 100.8%(RSD=0.67%,n=6).CONCLUSION: The established standard is applicable for the quality control of Yanyan pills.

60 years, 13.3% of the total sarcoidosis patients) diagnosed as sarcoidosis based on national criteria from the year 1965 through 1999 were reviewed. Results The clinical degree was as follows: phase I, 8 cases; phase Ⅱ, 6 cases; phase Ⅲ, 2 cases. The elderly sarcoidosis patients manifested variously, with misdiagnosis rate being 50%. The active degree of pulmonary sarcoidosis was correctly evaluated after the diagnosis was confirmed and the patients was strictly observed during the treatment since it was very important for avoiding the occurrence of complications. Conclusions The early diagnosis in elderly patients with sarcoidosis should be emphasized to prevent them from missing and misdiagnosis. The elderly patients with treating indications in phases Ⅱ and Ⅲ could be given steroids and constant observation and regular examinations are important during the treatment.

Objective To certify whether 99mTc-HL91 can be trapped in ischemic myocardium prominently for clinical imaging. Methods The model of myocardial ischemia in rabbits was prepared and the distribution of 99mTc-HL91 was observed. The distribution of 99mTc-HL91 in the whole body was also observed. Results The myocardium of the left ventricle supplied by LCX was ischemic according to the change of electrical physiology and the results of NBT dying. The radioactivity in the myocardium of left ventricle supplied by LCX was higher than that supplied by LAD. LCX/LAD: 120 min, 2.57; 180 min, 3.45. 99mTc-HL91 was mostly distributed in the liver and kidney, next, the stomach and intestine. It was excreted through urination and defecation. There was little radioactivity in the heart and lungs and it eliminated quickly. 99mTc-HL91 was eliminated quickly from blood, too. Conclusion Ischemic myocardium can trap 99mTc-HL91 more significantly and relatively prominently at 180 minutes of post-injection. 99mTc-HL91 can be used in myocardial hypoxia imaging.

Objective To explore the clinicopathologic features,diagnostic criteria and clinical prognostic factors of Goblet cell carcinoid (GCC) of the appendix.Methods The clinical and pathological data from 6 GCC patients were analyzed including age,clinical stage,surgical procedure,outcome,macroscopic features,histological sections and immunohistochemistry.Results The median age was 49.67 years old.Clinically,4 patients presented the signs and symptoms of acute appendicitis,while 2 patients presented the signs and symptoms of abdominal pain.4 patients of them undergone the simple appendectomy,the other 2 undergone the right hemicolectomy.All patients who had undergone the operation treatment survived.One patient was lost to the follow-up.Macroscopically,no masses were found in the appendix.Microscopically,4 cases showed that the tumor cells were identical to the goblet cell normal small intestinal crypts morphologically.The atypia,necrosis and mitotic figures of neoplasm cells were absent.2 cases were composed of small,discrete acini,tubules lined by a single layer of cuboidal or columnar cell,the signet-ring cells were uniform with pattern of infiltration being nests,rosrttes,or clumps without a dintinct lumen.All GCC cases were positive to Syn,4 cases were positive to CgA,some cases expressed NSE,CD56,CK7,CK20,Ki-67 index of 5 cases was under 2 ％,the other 1 was 3 ％.None had lymph node metastases,intestinal metastases or ovary metastases.Conclusions GCC of appendix is a rare neoplasm,and has more aggressive behaviour than classic carcinoids.Positive expression of Syn and CgA is necessory for the diagnosis of GCC,Ki-67 index may suggest the grading of tumor.
