Objective:To study the pharmacokinetics of indometacin (IDM) enteric-coated dropping pills.Methods:Beagle dogs were used as the experimental animals and the marketed IDM enteric-coated tablets were applied as the control,the pharmacokinetics of IDM enteric-coated dropping pills was studied after a single oral administration.DAS software was used for the model fit and parameter calculation,and the bioequivalence was also evaluated.Results:Both IDM enteric-coated dropping pills and tablets were fitted a one-compartment model.Compared with those of IDM enteric-coated tablets,the Cmax,Tmax,AUC0-∞and Tlag of IDM enteric-coated dropping pills all showed notable differences (P<0.05),and the former two increased significantly,and the latter two were shortened significantly.The relative bioavailability of the dropping pills was (121.0±7.7)%.Conclusion:Compared with IDM enteric-coated tablets,IDM enteric-coated dropping pills are with significantly enhanced absorption and shortened lag time,which is worthy of further studies and development.

Objective To investigate the possible mechanism of the biologic ethology effects of NGF and SP(substance P)on primary cultured adrenaline medullary chromaffin cells(AMCC).Methods To establish primary cultured AMCC by means of enzyme digestion and purify the cells by means of isopycnic gradient centrifugation and differential plating.To observe the morphological and ultrastructural changes after the addition of NGF and SP,and detect the concentration of adrenaline and noradrenaline in serum by ELISA.Results Confervaceous processes could be observed after 2 d of addition of NGF to the culture and the processes strenched longer as days went by the observation of electron microscopy.there are some drumstick-like and villiform processes in the cell membrane and some vesiculation be observed near the cell membrane of the primary cultured AMCC cells after the addition of NGF.The bioblast was abundant but the structure was not clear in the intracytoplasm and the concentration of adrenaline were decreased(P

Objective To investigate the effects of patient-controlled intravenous analgesia (PCIA) with lornoxicam and fentanyl on arrhythmia and the expression of platelet membrane glycoproteins in patients with coronary artery disease (CAD) after abdominal surgery.Methods Eighty ASA II or III patients with CAD aged 51-66 yrs weighing 59-68 kg presenting for bdominal surgery participated in this study. CAD was diagnosed by clinical symptoms and ischemic changes on ECG. The patients were premedicated with intramuscular henobarbital 0.1 g and scopolamine 0.3 mg. Anesthesia was induced with fentanyl, droperidol, propofol and vecuronium and maintained with propofol, fentanyl and vecuronium. The patients received PCIA after operation. The PCIA solution contained fentanyl 0.9 mg and droperidol 5 mg in 100 ml of normal saline (N.S. ) in group A ( n - 40) or lomoxicam 56 mg, fentanyl 0.2 mg and dropendol 5 mg in 100 ml N.S. in group B ( n = 40). In group A the loading dose was fentanyl 0.05 mg and in group B lornoxicam 4 mg. PCIA included a background infusion at 2 ml ? h-1 and a bolus of 0.5 ml with a 15 min lock-out. VAS (0 = no pain, 10 = worst pain) was used to measure pain intensity In addition to BP, HR and SpO2 monitoring ECG was continuously monitored with a Holler monitor after operation Blood samples were taken from peripheral vein before and 6h after operation and on the 1st, 2nd, 7th and 8th postoperative days for determination of the expression of CD62p, CD63 and CD41/CD61 on the platelet membrane, platelet count, prothrombin time ( PT) thrombin time (TT) and partial thromboplastin time (PTT) Results The two groups were comparable with respect to sex, age, body weight, severity of CAD, duration of operation and intraoperative blood loss. The patients received no blood transfusion during operation. There was no significant difference in VAS score, platelet count, PT, TT and PIT between the two groups. The incidence of atrial and ventricular premature beat on ECG and the expression of CD41 /CD61 , CD62P and CD63 on the platelet membrane were significandy lower in group B than in group A on the 7th and 8th postoperative days (P

Objective To investigate the expression of nerve growth factor(NGF)in the adrenaline medullary chromaffin cells(AMCC)and the morphological and functional changes in AMCC of asthmatic rats.Methods The 32 SD rats were randomly divided into two groups:control group(n=8)and asthma group(n=8).Asthma models were established by sensitization and challenge with ovalbumin(OVA).By means of immunohistochemistry(SP)combined with the micro-image analysis to investigate the alterations of NGF immunoreactivity in asthmatic rats and by means of light microscopy and electron microscopy to investigate the ultrastructural changes in AMCC,and detect the concentration of adrenaline and noradrenaline in serum by enzyme-linked- immunosorbent assay(ELISA).Results The positive immunoreactivity was increased in asthmatic AMCC compared with the controls(P

Objective To study the technique of totally extraperitoneal laparoscopic hernioplasty(TEP). Methods 16 patients with inguinal hernia were treated with TEP.There were 14 indirect inguinal hernia and 2 direct inguinal hernia.All patients were treated by laperoscopic herhisplasty through extraperitoneal route. Results All cases were operated on successfully.Operation time was 65.5(40～120)min.The average postoperative hospital stay was 3.7(3～7)days.No complication occurred.There was no recurrence. Conclusionss TEP is a satisfactory technique with a low recurrence rate and a low major complication rate.

To evaluate the safety and efficacy of transrectal high-intensity focused ultrasound (HIFU) in the treatment of benign prostatic hyperplasia (BPH), serial studies were conducted in 150 BPH patients before and 30 min, 1, 2, 6 and 12 month(s) after Sonablate-500 HIFU treatment. A silicon-coated indwelling 16F latex catheter was placed during the determination of the therapy zone. Preoperative and postoperative evaluations were made by using the international prostate symptom score (IPSS), quality of life (QOL), uroflowmetric findings and transrectal ultrasound, and incidence of complications. The cystourethrography was done in 23 patients within 1 year postoperatively. The results showed that after HIFU treatment, IPSS and QOL scores were significantly decreased at 1, 2, 6 and 12 month(s) (P<0.01). Maximum urine flow rate (6.0 to 17.2 mL/s, P<0.01), PVR (75.0 to 30.3, P<0.01) and prostatic volume (65.0 to 38.1 mL, P<0.05) were significantly improved 12 months after the operation. Recurrent urinary retention (n=2) and urethrorectal fistula (n=1) occurred at the 15(th) postoperative day. The duration of the HIFU prostate ablation was 25-90 min. The mean time for an indwelling catheter was 3-19 days. These data demonstrate that treatment of BPH with Sonablate-500 HIFU is safe and effective.

Objective: To develop a new quantitative determination method for the biological activity of recombinant human ciliary neurotrophic factor. Methods: Dorsal root ganglions were derived from the chick embryo and dispersed into single neuron cell,The rhCNTF was added to neuron cells and incubated for 64 hours,The activity of acid phosphatase in neuron cells was determined and the biological activity of rhCNTF was analyzed quantificationally. Result: rhCNTF could promote original era dorsal root neuron cells of chick embryo surviving,the livability of neuron cells was positively related to the amount of rhCNTF added to the culture. Conclusion: A quantitative determination method for the biological activity of rhCNTF was developed by testing the activity of acid phosphatase in neuron cells. Compared with the typical ways,this method was quantificational easily,repeatable better and with much fewer disturbance factors.

Objective To evaluate the matching degree of donor's and receptor's tissue typing and analyze the relationship between the degree and the early survival of cardiac transplantation with donor's and receptor's tissue typing of 9 cases of cardiac transplantation. Methods In accordance with the international standard, donor's and receptor's blood type, HLA antibody, lymphocytotoxicity and panel reactive antibody were determined in 9 cases of cardiac transplantation, and the donor's and receptor's matching degree evaluated by methods of amino acid triplets and cross-reactive group. Results Of 9 cases, 6 survived while 3 died. Of the 3 dead cases, 2 came respectively from the two best comprehensively evaluated matching cases and two worst, and postoperative biopsy showed that there was no rejection in either survival cases or the dead cases. Conclusion With the effective immunosuppressant, the HLA typing doesn't affect the early survival.
