Hepatocellular carcinoma (HCC) is one of the most lethal human cancers in China. The specific molecular mechanism of its occurrence and development is unclear. Krüppel-like factor family (KLF), which includes 17 members, is a highly conserved transcrip-tion factor family with zinc finger structure. The mechanism of KLFs and the pathogenesis of HCC have been studied in recent years. Re-search revealed that KLF2, KLF4, KLF5, and other KLF family members could be involved in the progression of proliferation, differentia-tion, invasion, and metastasis of HCC. This review summarizes the function and the mechanism of transcription factors KLF in the oc-currence and development of HCC.

Objective To explore the correlation of the apoptosis of peripheral blood mononuclear cell (PBMC) with plasma 8-iso-prostaglandin F2? (8-iso-PGF2?) level in order to confirm the peroxidation damage of hyperbilirubinemia in neonates with jaundice.Me-thods One hundred and twenty-nine neonates who were 2 to 7 days old were divided into 4 groups:slight jaundice (43 cases),moderate jaundice (38 cases),serious jaundice (18 cases),and healthy control(30 cases)groups.Plasma 8-iso-PGF2? levels were assayed by enzyme immunoassay(EIA),and the apoptosis rates of PBMC were determined by flow cytometry.Results 1.There was no significant difference in the apoptosis rate of PBMC between normal and slight jaundice neonates (P=0.108);apoptosis rate of PBMC was increasing with the aggravation of jaundice.2.Plasma 8-iso-PGF2? level in normal neonates was 14.74?6.71 ng/L,there was no difference between normal neonates and neonates with slight jaundice(P=0.502).Plasma 8-iso-PGF2? levels in neonates with moderate and serious jaundice were much higher(Pa=0).3.Positive correlation existed between plasma 8-iso-PGF2? level and PBMC apoptosis rate (r=0.602 P=0).Conclusions Hyperbilirubinemia can induce peroxidation damage,resulting in increase of PBMC apoptosis.Plasma 8-iso-PGF2? level can accurately eva-luate the peroxidation damage in neonates with jaundice.

OBJECTIVE:To review drug use in the pediatric outpatient department of our hospital.METHODS:1000pediatric prescriptions during Aug.1to Aug.20,2004and another1000during Aug.1to Aug.20,2005were collected from the pediatric outpatient department of our hospital,and which were subjected to statistical analysis using international indicators of rational drug use and DDDs.RESULTS:The usage of injection accounted for12.3%in2004and11.4%in2005.The usage of anti-infectives stood at84.20%in2005,accounting for46.11%of total drug consumption sum.Azithromycin and cefaclor respectively dominated the first place on the lists of consumption sum and DDDs.CONCLUSION:The practice of Prescription Management Rules(trial)helps improving the use of injections in the pediatric outpatient department of our hospital.However,there are still many problems,which needs to be tackled in the application of anti-infectives and further intervention measures needs to be taken.

Objective To evaluate the clinical significance and the mechanism of immunotherapy with autologous tumor vaccine. Methods 400 patients with pathological diagnosis of malignant tumor were enrolled in this study. 5 days after operation, the patients received vaccination of autologous tumor vaccine every 2-3 days for 5 times. 3 days before and 7 days after administrations, the peripheral blood mononuclear cells (PBMC) were isolated to assay the alteration in the proportions of CD3,CD4,CD8,CD4/CD8, and NK cells. Meanwhile, serum IL-2 and IFN-? were measured. Results After active immunotherapy with autologous tumor vaccine, the proportions of CD4 and CD4/CD8 were significantly elevated, while the proportion of CD8 and NK showed no difference. All the patients tolerated the vaccine well without serious side effects, such as skin ulceration. Conclusion The autologous tumor vaccine can elicit specific cellular immune response, and may be a potential approach to treat the cancer.

Objective To search for a better way than DSA to display the bronchial arterial (BA) supply of spinal cord, esophagus, trachea, etc., and for further evaluation of BA supply to the above structures, along with reducing the complications of trans-BA infusion and/or embolization. Methods Multislice CT angiography of BA (BA-MSCTA) was performed on 19 patients suffering from lung cancer or hemoptysis due to bronchiectasis after undergoing digital subtraction angiography BA (BA-DSA). Totally 10ml of 45% contrast medium was injected into BA (1～2 ml/s), BA-MSCTA was started 5 s after the injection, scanning from low cervical region to the bottom of lung (collimation: 5 mm; no overlapping reconstruction ). The intra-spinal canal, esophagus, trachea, etc. were enhanced. Results On BA-DSA, except one case in which a bronchial artery was faintly displayed, no spinal artery, intra-spinal canal, esophagus or trachea enhancement could be demonstrated. While on BA-MSCTA, intra-spinal canal associated with an intercostobronchial trunk enhancement due to truncus formation were observed in seven cases, including five cases of spinal enhancement (5/19,26.3%). 15 cases of esophageal enhancement and 18 cases of tracheal enhancement were also observed. Conclusion BA-CTA is superior to BA-DSA in displaying the BA supply of spinal cord, esophagus, trachea, etc.. Spinal arteries are more likely to appear in intercostobronchial truncus cases.

AIM: To establish the method of determining cinobufagin and resibufogenin in Xinkening Capsules(Venenum Bufonis,etc.). METHODS: HPLC was applied to determining cinobufagin and resibufogenin.The determination was carried out using an ODS column with a solvent system: methanol-water(50∶40).The flow rate was 1.0 mL/min,detection wavelength was at 296 nm. RESULTS: The linear ranges of cinobufagin and resibufogenin were 3.5 ?g-0.28 ?g and 3.75 ?g-0.30 ?g,respectively.The average recoveries of cinobufagin and resibufogenin were 99.86%(RSD=1.8%,n=5),and 99.84%(RSD=1.2%,n=5),respectively. CONCLUSION: This method is simple,accurate with strong specificity and can be used to control the quality of Xinkening Capsules.

0.05). The levels of PT, APTT, TT were longer and INR was higher and FB, PTA were lower in two groups at the end of operation than at the preoperative day (P0.05). CCABG group was higher than OPCABG group in Allogeneic blood transfusion (P

Objective: To research the clinical curative effect and explore the mechanism of penetrating of scalp-point on acute hypertensive intracerebral hemorrhage (ICH). Methods: 66 patients were randomly divided into two groups: one is the scalp-point therapeutic group, the other is the western medicine group. The two groups were all treated by dehydration, etc. In addition, there are 20 normal people to be set as the healthy group. To select the nervous functional deficit mark, activity of daily living (ADL) form, the amount S-100B protein as indexes and analysis the results. Results: the recordings indicate the patients' Serum S-100B protein are related with nervous functional deficiency mark. After 28 days, the recovery of patients' nervous function of scalp acupuncture group was obviously superior to that of control group (P＜0.05). Conclusions: The results suggested that the patients' Serum S-100B had positive correlation with nervous functional deficit; The penetrating of scalp-point had the better regulatory effect on the level of Serum S-100B, and could improve the nervous functional deficit and ADL, so as to improve the coordination and compensation function and the general nervous function between cortical functional areas

Objective To explore the changes and relationship of serum insulin-like growth factor-1(IGF-1) and leptin in children with growth hormone deficiency(GHD).Method Serum IGF-1 and leptin levels were measured by immunoradiometric assay in 20 prepuberal normal children and 23 children with GHD.Results Serum IGF-1 level in GHD group(51.158?29.988)?g/L was significantly lower than that in controls(112.680?41.540)?g/L.Serum leptin levels in GHD group(6.002?2.204)?g/L was significantly higher than that in controls(4.523?2.204)?g/L.There was no significant correlation between serum IGF-1 and leptin.Conclusion IGF-1 and leptin regulate growth in children with GHD in their individual way.
