Objective: To provide information for strenthening the management of antibacterials through an investigation of the clinical use of antibacterials in the Department of Pediatrics in the people's hospital of Haiyan.　Methods: A retrospective review of the medical records of all the inpatients discharged from the Department of Pediatrics of the hospital during the period of January 1999 to December1999 was carried out regarding the application of antibacterials for them. 　Results: Antibacterials were used in 95.76% of the patients, with a period averaged 3.8 days. The most frequently used three antibacterials were cephalosprin, aminoglycoside and macrolides. The rate of unreasonable use of antibacterials was 34.55%. Antibacterials selected on basis of susceptibility tests was 20.61%. The main administration route was intravenous drip. 　Conclusion: In order to prevent drug resistance of the bacteria and decrease adverse effects of antibacterials, it was very important to strenthen management of reasonable use of antibacterials and application of susceptibility tests and raise the awareness of the side effects of antibacterials on children.

Effects of the extracts from Lapemis hardwickii on RBCs count and Hb content were studied in the both of mice model of which was made by acetylphenyhydrozine (APH) for hemolytic anemia and of by Chinese rubarb for Xue Xu (debility due to blood deficiency). The results showed that counts of red blood cell (RBC) and content of hemoglobin (Hb) of experimental group in hemolytic anemia model mice were higher significatly than that of control gooup in hemoly ticanemia mice. The content of Hb was increased in Xue Xu mice model,but no marked effect on the counts of RBCs. The study showed that the extract could have a better profective effect on red blood cells of hemolytic anemia mice.

Objective To evaluate the effectiveness, safety and clinical feasibility of long-term drainage following percutaneous transhepatic cholangiography and drainage (PTCD) for the treatment of ischemic-type biliary lesion (ITBL) after liver transplantation. Methods There were 11 patients with ITBL after liver transplantation. Of the 11 patients with a mean age of 42. 3, 10 were male and 1 female. All 11 cases were diagnosed by PTC or ERC (endocopic retiogiade cholangiogiaphy) before PTCD, and they responded poorly to medication or draining and stenting with ERCP. Long-term drainage following PTCD was performed, whereas adjuvant percutaneous aspiration through double guidewire technique was used for the patients with large quantities of chole mud. Results There were three types of ITBL: type Ⅰ (extrahepatic lesions, n=7), type Ⅱ (intrahepatic lesions, n= 1), and type Ⅲ (intra- and extra-hepatic alterations, n=3). PTCD was performed in all 11 patients successfully. The values of total bilirubin (TBIL) and direct reacting bilirubin (DBIL) were 206.70±54.18μmol/L, 170. 65±53. 97μmol/L and 90. 63± 13.00μmol/L, 63. 83± 13.61μmol/L before and 1 week after PTCD, respectively. The follow-up period was from 3 through 71 months (mean 20 months). During the follow-up, TBIL values ranged between 23.70 μmol/L and 241.0 μmol/L (mean 55.3±15.6 μmol/L), and DBIL values were between 8. 1 and 162.0 μmol/L (mean 32. 53±10. 21 μmol/L). Hepatic functions were good in 9 cases including 5 cases in which the drainage tube was withdrawn after long-time drainage (6～ 12 months, mean= 8.2 months) and 4 cases in which drainage continued. The other 2 cases received liver retransplantation for the grafts dyssynthesis of albumen after drainage for 3 and 8 months. Conclusion Long-term drainage following PTCD is an effective and safe approach for ITBL following liver transplantation.

Objective To analyze the factors that might affect the therapeutic results of pingyangmycin-lipiodol emulsion intra-arterial sclerosing embolization (PLE-IASE) in treating symptomatic cavernous hemangioma of liver (SCHL). Methods PLE-IASE was performed in 89 patients with SCHL (32 males and 57 females). Before treatment the mean diameter of the hemangioma was (8.3±3.8) cm. Of 89 patients, 53 experienced anxiety, 35 suffered from right upper abdominal pain and the remaining one developed Kasabach-Merrit syndrome. Before PLE-IASE, the arteriographic classification was conducted based on hepatic arteriographic findings. Then pingyangmycin-lipiodol emulsion (PLE) was injected through the feeding artery. The dosage of pingyangmycin (PYM) was (9.8±4.4) mg and the dosage of lipiodol (LP) was (5.9±2.9) ml. The lipiodol deposition status was judged by the follow-up spot film taken immediately after PLE-IASE. The observations of the occurrence of complications, the relief of symptoms and the minification of SCHL were followed for 6-72 months after PLE-IASE. The linear regression analysis statistics was conducted by taking the minification as dependent variable and taking the arteriographic classification, lipiodol deposition status, the dosage of PYM, the dosage of lipiodol and the preoperative SCHL diameter as independent variable. Results Of all 89 cases of SCHL, hypervascular type was seen in 51, hypovascular type in 26 and arteriovenous shunt (AVS) type in 12. Good lipiodol deposition status was found in 64 patients and poor deposition in 25 patients after PLE-IASE. After PLE-IASE, the symptom of anxiety in 53 patients was relieved and the right upper abdominal pain was reduced in 33 cases although intermittent pain still remained in 2 patients. The blood platelet count of the patient with Kasabach-Merrit syndrome returned to normal after the treatment. The symptomatic relieve rate was 98.7%. No serious complications occurred in the follow-up period. The linear regression analysis showed that arteriographic classification, lipiodol deposition status and PYM dosage used in treatment had statistically significant impact on tumor minification, while the preoperative diameter of SCHL and lipiodol dosage used in treatment had no statistically significant impact on it. Conclusion PLE-IASE is an effective and safe interventional treatment for SCHL. Arteriographic classification, lipiodol deposition status and PYM dosage used in treatment have a significant correlation with the minification of SCHL, while the preoperative diameter of SCHL and lipiodol dosage used in treatment bear no relationship to the minification of SCHL.

BACKGROUND: Chinese medicine Gukang prescription has a clear effect on clinical treatment of osteoporosis, but the therapeutic pathway is stil unclear.
OBJECTIVE:To investigate the effects of Chinese medicine Gukang on the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin by regulating core binding factor alpha 1 expression to control the growth and development of osteoblasts.
METHODS:Sprague-Dawley neonatal rats within 24 hours after delivery were used for the separation and culture of osteoblasts. Adult Sprague-Dawley rats were used to prepare drug-containing serum, and then divided into two groups randomly:normal control group and Gukang group. Rats in the normal control and Gukang groups were intragastrical y administrated with extract of Gukang prescription and normal saline based on rat’s body surface area, for 1 consecutive week. Two hours after the last administration, blood samples were taken from the heart. Then the serum was col ected. Osteoblasts at passage 3 were confirmed with alkaline phosphatase assay and digested. After counting and planting, al osteoblasts were divided into two groups and treated with col ected
serum for 72 hours. Proliferative rate of osteoblasts was detected by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test. Secretion of alkaline phosphatase was detected by using enzyme linked immunosorbent assay and corrected with the corresponding absorbance value. mRNA expression of core binding factor alpha 1, receptor activator of nuclear factor kappa B ligand and osteoprotegerin were detected by using reverse
transcription-PCR in al groups.
RESULTS AND CONCLUSION:mRNA expression of osteoprotegerin and core binding factor alpha 1 in the Gukang group was significantly higher than that in the normal control group, but protein and mRNA expression of receptor
activator of nuclear factor kappa B ligand were dramatical y lower in the Gukang group compared with the normal control group (P<0.01). These findings indicate that Chinese medicine Gukang prescription can modulate the expression of
core binding factor alpha 1, thereby adjusting the expression of receptor activator of nuclear factor kappa B ligand and osteoprotegerin, which may be one of the mechanisms underlying Gukang treatment for osteoporosis.
