OBJECTIVE:To provide references for the management and use of the donated drugs for earthquake resistance and disaster relief.METHODS:The problems appeared in the management and use of the donated drugs after the earthquake occurred on May 12,2008 in Sichuan province of China were summarized analytically and the corresponding suggestions were put forward.RESULTS & CONCLUSION:Some problems such as the turnover of the drugs,the expiration date,drug dispensing and allocation etc appeared in the management and use of the donated drugs,which should be standardized by setting related laws and regulations to make more greater use of the limited drug resource in the disaster relieving.

Objective To assess the clinical effects of Shenfu injection which consists mainly of panaxoside and water-solubility alkaloied on chronic pulmonary heart disease complicated with heart failure.Methods Ninetysix patients were randomly divided into two groups ,40 patients underwent regular treatment (control group) and 56 patients were treated with Shenfu injection additionally to regular treatment (treatment group ).There were 2 treatment durations,with 15 days in one duration.The symptoms,left ventricular ejection fraction (LVEF) and B type UNa peptide (BNP) were measured before and after treatment.Results The total effective rate in the treatment group was 91.1% (51/56) ,which was significantly higher than that in the control group (72.5% ,29/40) (P ＜0.05 ).After treatment,the treatment group has significantly higher LVEF than the control group(53.27% ±7.45%vs.49.12% ± 5.89% ) ( P ＜ 0.05 ),and significantly lower BNP ( ( 209.1 ± 18.7 ) ng/L vs.( 261.2 ± 19.3 ) ng/L ( P ＜ 0.05).Conclusions Shenfu injection could strengthen the contractility and increase LVEF,therefore improve the function of left ventricle,as well as decrease BNP and repair heart failure.

Objective To study the circadian changes of blood pressure and urinary catecholamine excretion in patients with pheochromocytoma before and after tumor removal. Methods Twenty-seven patients with pheochromocytoma were examined by 24h ambulatory blood pressure monitoring before tumor removal, and 12 of them were examined by ambulatory blood pressure monitoring both before and after operation, meanwhile, their urinary norepinephrine (NE), epinephrine (E) and dopamine (DA) excretions of 10 time-segmental portions of urine at the same day were determined by HPLC method. The circadian changes were analyzed by Cosinor method. Results The circadian changes of catecholamine excretion were observed, and the peak excretion time of E and DA were shifted to 14:00-16:00. The circadian changes of systolic and diastolic blood pressure disappeared in patients with sustained hypertension and existed in patients with paroxysmal hypertension. The circadian changes of blood pressure and urinary catecholamine excretion were returned to normal after surgery. The circadian change of heart rate was observed both before and after operation. Analysis of data from 12 cases with pheochromocytoma showed strongly positive correlationsbetween24hmeansystolicanddiastolic blood pressure and mean urinary NE excretion (r=0.83, 0.91, P

Objective To evaluate the optimal dosage of misoprostol administered in the rectum for dilation of the cervix. Methods Two hundred and forty women at 40-60 day gestational age without vaginal delivery history were randomly divided into three groups,with 80 cases in each group. Patients received 200,400 or 600μg of misoprostol rectally one hour before electrical vacuum abortions in group A,B and C,respectively. Cervical dilation,blood loss,and drug side effects in the three groups were compared. Venous blood samples were taken before vein anesthesia,and misoprostol acid concentration in the serum was tested by liquid chromatography-mass spectrometry. Results The analgesic rate was 100. 00%in all three dose groups, and cervical dilation rate was 23. 75%,46. 25%and 70. 00%in groups A,B and C,respectively. The severity of drug side effects such as vaginal bleeding and abdominal pain is dose-dependent. Blood concentration of misoprostal acid was(117±65),(206± 98),and(303±149)pg·mL-1 ,in groups A,B and C,respectively. Conclusion The recommended dose of misoprostol is 400 μg administered in rectum. Rectal administration of misoprostol is cheap,safe,and convenient,and therefore could be widely applied.

Objective To observe the influence of serum containing Tongmai on the anoxic myocardial cell. Methods The serum containing Tongmai effective components was extracted and used to interfere the anoxic myocardial cell, then the concentration of the LDH and troponin I in the culture medium of the cardiac myocyte was measured. Results The concentration of LDH and troponin I increased significantly in the culture mediun of the anoxic cardiac myocyte. The intervention of the serum containing Tongmai can significantly decreased the concentration of LDH and troponin I in the culture medium of the anoxic cardiac myocyte. Conclusion Tongmai can protect the cardiac myocyte from anoxic damage.

BACKGROUND: Our previous studies have found that the Kangguzengsheng Capsules can promote fracture healing.OBJECTIVE: To explore the influence of Kangguzengsheng Capsules-containing serum on the proliferation andosteogenic differentiation of bone marrow mesenchymal stem cells.METHODS: Forty Sprague-Dawley rats were randomly divided into four groups. The capsule powder was resolved into1 mL natural saline and intragastrically administered into rats according to 1.16 g/100 g, 3.48 g/100 g, 10.44 g/100 g in low,medium and high dose groups. Rats in control group were given equal volume of natural saline. After consecutiveadministration for 12 days, blood samples from the abdominal aorta were collected and serum samples were isolated andpreserved until use. Bone marrow mesenchymal stem cells were isolated and purified by the whole marrow adhesion method,and identified by flow cytometry. Harvested cells were divided into four groups and cultured in the osteogenic culture mediumcontaining different kinds of serum samples as described above. MTT method was adopted to test the cell proliferation at 24,48 and 72 hours of culture. Alkaline phosphatase activity in cells was detected at 7 and 14 days of culture. Alkalinephosphatase staining was performed at 7 days of culture, and alizarin red staining performed at 14 days of culture.RESULTS AND CONCLUSION: Compared with the blank control group, bone marrow mesenchymal stem cells showedno significant changes in the proliferative ability and alkaline phosphatase activity in the low dose group, but these twoindices were significantly increased in the high and medium dose groups at 48 and 72 hours of culture or at 7 and 14days of culture, respectively (P < 0.05). Cells positive for alkaline phosphatase and alizarin red staining were observed inthe low, medium and high dose groups, and the cell staining was most remarkable in the high dose group. To conclude,Kangguzengsheng Capsules-containing serum can promote the proliferation and osteogenic differentiation of bonemarrow mesenchymal stem cells.

Objective To evaluate the apical sealing ability of iRoot SP root canal sealer in oval-root canal. Methods After root canals were instrumented by Mtwo, 28 premolars with oval-root canal were randomly divided into 2 groups, 14 teeth in each. The root canals were obturated with AH Plus (group A) and iRoot SP (group B) by modified continuous wave condensation technique. The apical leakage was evaluated by dye penetration method and transparent teeth technique. Results Mean depth of leakage was (0.92 ± 0.26) mm for group A and (0.84 ± 0.40) mm for group B. There was no significant difference between the two groups (t=0.506, P > 0.05). Conclusion The apical sealing ability of iRoot SP is equivalent to AH Plus in oval-root canal.
