Twenty-six eyes which appeared rejection after allograft penetrating keratoplasty between April 2003 and April 2004 in Shandong Shi'erming Eye Hospital were collected, including 16 males and 10 females, 9 cases were repeated relapsing viral keratitis, 8 cases were traumatic posterior corneal leucoma, 5 cases were corneal decompensation caused by various intraocular surgery, 2 cases were congenital leucoma, and 2 cases had other symptom. The rejection occurred at 2 month to 2.5 years after operation. Among them 19 cases were transferred to our hospital and asked adding traditional Chinese therapy because western medicine was ineffective in other hospital. All cases were received local treatment with hormone and non-steroidal anti-inflammatory eyedrop, some cases applied systemic administration with glucocorticoid, mainly based on eye black immunosuppression decoction, potion daily, twice per day, the average time of medication was 11-42 days. Clinical symptoms were served as observation indexes, results showed that the total effective rate of the 26 cases were 100%. The bulbar conjunctiva hyperemia and edema was reduced, corneal opacity became light, and rejection was complete response in 9 cases, 5 of 19 cases which were transferred to our hospital were exempted from operation, and the average vision was improved three lines. It was found that purging liver and eliminating dampness compound Chinese medicine can rapidly reduce anterior chamber's inflammatory response and backoff corneal neovascularization in clinical practice.

Objective To investigate the clinical significance in diagnosis and prognostic judgments of acute myelocytic leukemia with combined detection of morphology ,peripheral blood and immune typing of bone marrow cells .Methods Microscopic examina‐tion of bone marrow cell morphology ,automatic blood cell analyzer detection of peripheral blood parameter and flow cytometry anal‐ysis of immune markers of leukemia cells ,all these datas were analyzed statistically .Results Peripheral blood cell analysis showed that instruments may indicate the presence of abnormal or naive cells in about 85% patients ,different kinds of leukemia had signifi‐cant difference in total leukocyte count (majority higher in M1 - 2 ,M5 ;majority lower in M3) ;while anemia and thrombocytopenia were observed in most patients ,but the degree was different ;M1 - 2 and M5 can not be identified by classification of leukocyte by automatic blood cell analyzer ,CD7 ,CD10 and CD2 can cross express in myeloid leukemia ,which have a prompt effect with treatment and prognosis .Conclusion Detection of peripheral blood parameters has an important role in early screening ,differential diagnosis and prognosis judgment of leukemia ,immunological markers detection is the powerful supplement and support for leukemia diagno‐sis and typing ,sensitive markers have close contact with prognosis ,which significantly improves the effect of the diagnosis and treatment of leukemia .

Salvianolic acid A (Sal A) is one of the most effective compounds isolated from the root of Salvia miltiorrhiza. Up to now, several studies regarding the pharmacokinetic profiles of Sal A have been reported, however there is no such study reported in monkeys, the species which is more similar to human. The aim of this study is to develop a LC-MS method for the determination of Sal A in monkey plasma and apply it to the pharmacokinetic studies of monkeys. After single intravenous administration of Sal A, the plasma concentration-time curves were observed and the main pharmacokinetic parameters were calculated. The plasma concentration at 2 min (C2 (min)) values were (28.343 ± 6.426), (45.679 ± 12.301) and (113.293 ± 24.360) mg x L(-1) for Rhesus monkeys treated with Sal A at 2.5, 5 and 10 mg x kg(-1). The area under the concentration-time curve (AUC(0-∞)) values were (3.316 ± 0.871), (5.754 ± 2.150) and (13.761 ± 2.825) μg x L(-1) x h, respectively. Furthermore, this method was improved and applied to the simultaneous determination of Sal A, Sal B and Sal C, which provided useful information for preclinical studies and clinical trials of Sal A, Sal B and Sal C.

Objective:To prepare and optimize the formula of metoclopramide orally disintegrating tablets, and investigate the in vitro drug dissolution behavior. Methods:The formula was optimized by full-factorial experiment design, the ratio of mannotil to micro-crystalline cellulose ( X1 ) and the amount of disintegrating agent ( X2 ,%) were selected as the independent variables, and the friabili-ty ( Y1 ,%) , disintegration time ( Y2 , s) and metoclopramide dissolution ( Y3 ,%) were used as the dependent variables. The release rate of metoclopramide orally disintegrating tablets in different dissolution media was studied. Results:The optimum formula of meto-clopramide orally disintegrating tablets was as follows:the ratio of mannotil to microcrystalline cellulose was 2. 5∶ 1, and the amount of disintegrating agent was 6. 5%. The dissolution of metoclopramide orally disintegrating tablets in the different dissolution media was o-ver 80%. Conclusion:The formula design is reasonable, the preparation process is feasible and the quality can be controlled.

Objective To investigate the effect of leukotriene receptor antagonist montelukast on inflammatory factors in children with asthma.Methods Eighty children with moderate asthma who aged 6-14 years old were randomly assigned to 3 treatment groups:5 mg once daily montelukast,or inhaled 100 ?g twice daily budesonide and 5 mg montelukast with inhaled budesonide 100 ?g per day.Each dose group received medicine for 12 weeks.Before starting therapy and 12 months later,clinical effects were observed,and pulmonary function was measured in patients simultaneously;concentrations of serum and sputum eosinophil cationic protein(ECP), IL-5 and TNF-? were measured respectively;also the peripheral blood eosinophil (Eos)was counted.Results Following treatment,clinical evaluation was improved and there were significant increases in pulmonary function in asthmatic children.Compared with control group,the levels of serum ECP,IL-5,TNF-? and blood Eos counting increased significantly in asthmatic children.The blood Eos counting was significantly correlated with ECP concentration in serum of children with asthma(P

AIM: To observe the clinical effects of intravitreal injection of triamcinolone acetonide ( TA ) before vitrectomy for retinal detachment associated with choroidal detachment. · METHODS: Totally 23 cases ( 23 eyes ) of retinal detachment associated with choroidal detachment in our hospital were treated by intravitreal injection of TA 4-5d before 23-Gauge micro-invasive vitrectomy combined with silicone oil injection. All the cases were followed up between 6 to 9mo. The anatomic retinal reattachment, visual acuity, intraocular pressure and postoperative complications were observed and analyzed. ·RESULTS: After the surgery, the visual acuity of all patients were improved, with 9 eyes better than 0. 3 (39%), and 18 eyes better than 0. 05 (78%). The BCVA at 1wk, 1 and 3mo and last follow up were different compared with before operations (P<0. 05). The mean intraocular pressure was 4. 02±1. 47mmHg before injection, 13.69±4. 68mmHg before operation (P<0. 05), and17.72±5.87 mmHg after operation (P<0.05). The retina of all patients treated were reattached 2wk post-operatively. The retinal reattachment rate after the primary surgery and the secondary surgery was 87% and 100%, respectively. Post-operative complications included 7 eyes of transient high intraocular pressure, occurred during 12-14d after operations and returned to normal after less glucocorticoid eye drops and giving IOP lowering drugs. There were no intraocular hemorrhage, iatrogenic retinal breaks, infections, or lens injuries. · CONCLUSION: Intravitreal injection of TA before vitrectomy for retinal detachment associated with choroidal could improve the clinical effects, and decrease the difficulty of surgery while the injection itself is pretty safe.

Objective To explore the characteristics of dipyridamole 201 Tl myocardial perfusion imaging (MPI) SPECT in patients with dilated cardiomyopathy. Methods Thirty patients with dilated cardiomyopathy underwent pharmacological stress 201Tl MPI SPECT after intravenous infusion of dipyridamole (0. 56 mg/kg) for 4 min. The early and delayed SPECT images were acquired respectively at 10 and 240 min after 201Tl injection. The images were analyzed and reported by two or three experienced nuclear medicine physicians. Results All patients were found to have abnormal perfusion patterns at delay imaging, however 90.00% (27/30) were also abnormal at early images. Six patients had reverse redistribution. Conclusion Dipyridamole 201Tl MPI SPECT imaging may be of some value for the assessment of patients with dilated cardiomyopathy.
