Objective To explore the changes of plasma angiotensinⅡ (AngⅡ) and cardiac function,and the curative effect of children with acute viral myocarditis (VMC) treated with captopril(CAP).Methods Concentrations of plasma AngⅡ were measured with radio-immunity and cardiac function was detected by Doppler echocardiography for the VMC group (n=60) before and after treatment [the CAP group (n=30), the routine group (n=30) and the control group (n=30)].Results 1. The level of plasma AngⅡ significantly increased and the contractive and diastolic function obviously declined in children with acute VMC. There was a significant difference between VMC group and control group, with a significant correlation between the level of AngⅡand the contractive diastolic function.2. Compared with the level before treatment, the level of AngⅡ decreased and the contractive function obviously ameliorated in two groups; the diastolic function obviously ameliorated in the CAP group and did not ameliorate in the routine group after treatment. In CAP group the level of AngⅡ and the cardiac function significantly improved; there were statistical differences between the two groups after treatment.Conclusions 1.The increase of the plasma AngⅡ was an important factor for decrements of the contractive and diastolic function in acute viral myocarditis.2.It could decrease the concentration of plasma AngⅡ and ameliorate cardiac function in children with acute VMC treated with captopril,which was an effective therapy for acute VMC.

OBJECTIVETo detect the therapeutic effect of selenium-enriched garlic (SeG) on chronic gastritis.

METHODSChronic gastritis was induced of the glandular stomach of male Mongolian Gerbils via gastric instillation of H. pylori TN2 strain once every 4 days for 5 consecutive times followed by random classification into six groups. Fresh SeG suspension was administrated daily at dosages of 4.70, 1.5, 0.47, 0.15 g.kg(-1).d(-1) for four weeks. The gerbils in the positive control group were treated with omeprazole, clarithromycin, and amoxicillin for one week. The gerbils were killed for pathological examination four weeks after SeG-treatment.

RESULTSChronic gastritis (CAG), low-grade dysplasia or gastric intraepithelial neoplasia (DYS/GIN) were observed among 77% and 38.5% of the 13 H. pylori-treated animals in the negative control group, respectively; whereas 40% and 26.7% in the positive control group (n = 15), respectively. The incidences of CAG and DYS/GIN in the SeG groups (n = 21 - 27) were reduced dose-dependently, 16.7% - 38.7% and 11.1% - 14.3% for CAG and DYS/GIN, respectively.

CONCLUSIONSeG administration inhibits the development and progression of CAG induced by H. pylori remarkably.

OBJECTIVETo study the clinical therapy and prognosis in children with transient congenital hypothyroidism (CH).

METHODSFifty-seven children with CH diagnosed after neonatal screening were treated with low-dosage levothyroxine (L-T4). Follow-up evaluation included the determination of TT3, TT4 and TSH serum levels and the assessment of thyroid gland morphology, bone age, growth development and development quotients (DQ). A full check-up was performed at age 2, when the affected children first discontinued the L-T4 treatment for 1 month, and one year later. Development quotients were compared with a control group of 29 healthy peers.

RESULTSThe initial L-T4 dosage administered was 3.21-5.81 microg/(kg.d) with an average of (16.25+/-3.87) microg/d. Mean duration of therapy was (28.09+/-9.56) months. No significant difference was found between study group and control group in the DQ test (average score (106.58+/-14.40) vs (102.4+/-8.6), P>0.05) and 96.49% of the CH children achieved a test score above 85. Bone age, 99mTc scans and ultrasonographic findings were all normal, and evaluation of physical development was normal too, as were the serum levels of TT3, TT4 and TSH after one year of follow-up.

CONCLUSIONA L-T4 dosage of 3.21-5.81 microg/(kg.d) was found sufficient for the treatment of transient CH. The treated children showed satisfactory overall mental and physical development at age 2. So it is possible for CH children to stop taking medicine if their laboratory findings and physical development are all normal after regular treatment and 2-3 years of follow-up.

Roscovitine is a specific inhibitor of cyclin-dependent kinases (cdks) cdc2/cyclin B, cdk2/cyclin A, cdk2/cyclin E and cdk5/p35. The studies on the enzyme inhibitory properties and cellular effects of roscovitine revealed that it arrests cells in G(2)/M and G(1)/S phase, inhibits the proliferation of mammalian cells and induces cell death. However, the characteristics of cell death and exact mechanism by which this cdk inhibitor kills transformed cells are unknown. We previously investigated that the roscovitine induces apoptotic death of mitotic PC12 cells. The present study was to identify whether the roscovitine-induced death is related with the specific elements of caspases in pathway of apoptosis. The morphological data of caspase-3 immunofluorocytochemistry double staining with hoechst 33342 indicated that apoptotic nuclei were identified as nuclei with chromatin condensation and nuclear fragmentation, and that caspase-3 active p17 subunit co-existed in PC12 cells treated with roscovitine 50 micromol/L for 4 h. The number of the caspase-3 positive cells increased significantly to about 42%, as compared with the normal control (P<0.001). The data of MTT assay showed that the number of viable cells treated by roscovitine (50 micromol/L) alone for 12 h was 29.03%, of the untreated controls. Both a broad-spectrum caspase inhibitor Z-VAD-FMK (50 mumol/L) and a specific caspase-3 inhibitor Z-DEVD-FMK (100 micromol/L) increased viable PC12 cells to 45.16%, (Z-DEVD-FMK) and 58.06%, (Z-VAD-FMK), respectively, in the presence of roscovitine. Non-erythroid a-spectrin is a cytoskeleted protein that is a substrate of caspase-3 cysteine proteases. To confirm the activity of caspase-3 that produced in roscovitine (50 micromol/L for 12 h)-induced PC12 cell death, activated caspase-3 specific 120 kDa spectrin breakdown products (SBDP) were detected by Western bloting using the mouse anti-non-erythroid a-spectrin monoclonal antibody. The mean relative density of bands corresponding to caspase-3 specific SBDP levels were significantly increased in the cytosolic fractions treated with roscovitine, as compared to the normal control (P<0.001). These results indicate that caspase signals, especially caspase-3 signal are necessary for the progression of proliferating PC12 cell apoptotic death evoked by roscovintine.

OBJECTIVE: To observe the effect of sevoflurane on the induction and maintenance of anaesthesia in children, and to evaluate its safety and effectiveness. METHODS: Forty child patients who conformed to the selection standard were operated under anaesthesia with intubation.Without premedicant, all the patients inhaled 100% oxygen(1L/min) and sevoflurane by mask, and escalated the concentration of sevoflurane (to the maximum concentration 7%) until the lash reflex disappeared, and the maintenance concentration was controlled under 4%. All the patients were intubated, together with vecuronium 0.1mg/kg. RESULTS: With little tract excretion, the achievement ratio of induction by sevoflurane was 100%, and the children tolerated well. With stable hemodynajmics,1% approximately 4.0% maintenance concentration of sevoflurane during the operation showed effective anaesthesia, no decreased heart rate or blood pressure appeared, and all the patients' body temperature was normal. CONCLUSION Sevoflurane for children induction can bring fewer stimuli in the respiratory tract,less cardiac vascular inhibition and palinesthesia time. Anaesthesia in children induced by sevoflurane is safe and effective.
