0.05).Conclusions By our detection to healthy full-term neonates of their lipid levels,the recommended borderline up-limits of TC,TG and LDL-C are above 2.71 mmol/L,1.29 mmol/L and 1.12 mmol/L,respectively.The recommended up-limits are above 3.28 mmol/L,1.63 mmol/L and 1.78 mmol/L,respectively.

Increasing attention has been focused on the antitumor activity of artemisinin derivatives in recent years, for artemisinin had been reported to have cytotoxic effects against HL-60, P388 and MCF-7 tumor cells. We report here the synthesis and evaluation for antitumor activity of a series of artemisinin-ether derivatives bearing tetrahydropyrrole, morpholine, piperidine, substituted piperidines and azoles with various linkers. Sixteen 10-O-substituted dihydroartemisinin derivatives were designed and synthesized, all of which have never been reported in literatures and whose antiproliferative effects on human breast cancer MCF-7, MCF-7/Adr and HL-60 cells were determined by MTT assay or direct cell counting. Each of these artemisinin derivatives possessed better effects than dihydroartemisinin evidently against HL-60 and MCF-7 cells growth, while less potent than doxorubicin. All target compounds exhibited significantly improved potency compared to DHA and doxorubicin on the doxorubicin-resistant MCF-7/Adr cells, so did they in their sensitive counterparts MCF-7 cells. Among them, compounds GF02, GH04 and ZH04 showed strong activity against these three cell lines growth. Further research is undergoing.

Objective:To summarize the experiences of the surgical treatment of tumors in the posterior part of the third ventricle and pineal region. Methods: Twenty-seven patients with tumors in this region treated microsurgically from 1990 to 2000 were analyzed. The surgical indications, approaches, and operative key points were discussed. The prognostic factors were also analyzed. Results:Tumors were removed totally in 11 patients, removed subtotally in 7 and removed partially in 5. Biopsy and ventriculo-peritoneal shunt was performed in 4 patients. Of 17 patients in follow-up, 13 patients survived longer than 5 years. Conclusions: Most tumors in the posterior part of the third ventricle and pineal region can be surgically removed.Sufficient specimen obtained in the operation can confirm pathologic property of the tumor,guiding next chemotherapy and radiotherapy.

OBJECTIVETo explore clinical efficacy of Yiguanjian Decoction (YD) combined Adefovir Dipivoxil Tablet (ADT) in treating HBeAg negative chronic viral hepatitis B (CVHB) active compensated liver cirrhosis (LC) patients.

METHODSTotally 68 HBeAg negative CVHB active compensated LC patients initially treated were assigned to the treatment group and the control group using random digit table, 34 in each group. Patients in the control group took ADT alone, 10 mg each time, once per day. Those in the treatment group additionally took YD, one dose per day. The therapeutic course for all was 48 weeks. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) were detected once in every two weeks. Hepatitis B virus (HBV)-DNA and four items of serum liver fibrosis [procollagen type I (PCN), hyaluronidase (HA), procollagen III peptide (PCIII), laminin (LN)] were detected once per every 4 weeks. Abdominal ultrasound B was performed before and after treatment. The inner diameter of the portal vein and the size of spleen were recorded. The fibrosis degree of liver was evaluated using Fibroscan. Efficacy of Chinese medicine (CM) was evaluated between the two groups before and after treatment using CM syndrome integrals. Efficacy of Western medicine (WM) was also evaluated between the two groups using Child-Pugh grading. Results Compared with before treatment in the same group, ALT and AST levels restored to normal levels, HBV-DNA turned negative (HBV-DNA < or = 1 x 10(2)) in the two groups after 48-week treatment. Besides, levels of TBil, ALB, PCIV, HA, PCIII, and LN obviously decreased (P < 0.05, P < 0.01). Results of ultrasound B showed the inner diameter of the portal vein and the size of spleen decreased. Fibroscan results showed that the elasticity value of the liver obviously decreased (P < 0.05). Besides, post-treatment levels of PCIV, HA, PCEJ, and LN, and the elasticity value of the liver decreased more obviously in the treatment group than in the control group (P < 0.01). There was no statistical difference in post-treatment levels of ALT, AST, TBil, ALB, inner diameter of the portal vein, or the size of spleen between the two groups (P > 0.05). Compared with before treatment in the same group, scores of Chinese medical syndrome and Child-Pugh scores decreased in the two groups after treatment (P < 0.05, P < 0.01). Besides, scores of Chinese medical syndrome decreased more obviously in the treatment group than in the control group (P < 0.05). The effective rate was 8824% (30/34) in the treatment group, higher than that of the control group [67.65% (23/34)] with statistical difference (P <0.05). Conclusion Combined treatment of YD and ADT could significantly improve symptoms of CM and fibrosis degree of liver of HBeAg negative CVHB active compensated LC patients.

Objective To investigate the feasibility of ~1H-MR spectroscopy(~1H-MRS)imaging to quantitatively detect fatty liver.Methods Twenty patients with fatty liver and 11 healthy volunteers underwent plain CT scan,conventional MR imaging and ~1H-MRS analysis.The blood lipid and liver function were tested on the same day as the MR examination.~1H-MRS sequence measured the peaks of H_2O and lipid,and the areas under the peaks.The relative contents of the lipid compound were calculated,and compared with the results of CT scan and liver function tests.Results The CT values of the normal group and the fatty liver group were(59?9)HU and(24?11)HU respectively.On ~1H-MRS a protruding high H_2O peak and a flat low lipid peak were observed in the normal group,while the protruding high H_2O peak and a high lipid peak appeared in the fatty liver group.The values of lipid peak in the normal group and the fatty liver group were(0.05?0.01)?10~5,(0.70?0.24)?10~5 respectively(t=4.32,P0.05),the areas under the lipid peak were(1.36?0.73)?10~9、(2.35?1.15)?10~9 respectively(t=5.21,P0.05).Conclusion ~1 H-MRS imaging is feasible to quantitatively detect liver fat and is a non-invasive method for detecting early fatty liver.

Objective To investigate the change of the basic fibroblast growth factor(bFGF) leve in human detrusor muscle(DM)in bladder outlet obstruction(BOO)due to benign prostatic hyperplasia(BPH)and its implication.Methods Fifty-four patients with BPH were divided into two groups:the obstructive DM stability and instability groups;and 15 men with bladder tumor who underwent operation in the same period were enrolled in the control group.The bFGF mRNA level in DM was measured by reverse transcription and polymerase chain reaction(RT-PCR)and the bFGF protein level was measured by immunohistochemical staining method.Results The bFGF-mRNA expression level of bladder smooth muscle cells was significantly lower in the control group than that in the obstructive DM stability and instability groups(all P＜0.05),but there was no significant difference between the obstructive DM stability and instability groups(P＞0.05). Conclusions The expression level of bFGF mRNA in bladder DM is elevated in BOO due to BPH,but there is little or no correlation between the increased expression of bFGF mRNA and detrusor muscle instability.

Objective To study the effects of erythrecyte on brain edema after traumatic intrace- rebral hemorrhage(TICH)and explore the mechanisms of erythrocyte in brain edema development follow- ing TICH.Methods Firstly,the brain injury model of SD rat was established by applying a free-fall- ing device,then whole blood(WB),lysed RBC(LRBC)or parked RBC(PRBC)were infused with ste- reotactic guidance into injured cortex to produce the model of TICH.All rats were killed at 1,3,and 5 days after injury.The brain water content was measured,immunohistochomistry(SABC)was applied to test HO-1 and TNF-?expressions.Results 1.In WB group,PRBC group and TBI group,the brain water content was the highest on the third day.The brain water content of LRBC group was markedly higher on the first day than on the third and fifth days.Comparison among the four groups showed the wa- ter content was the highest on the 1st day in LRBC group,and on the 3rd day in WB and PRBC groups; there was no significant difference among the four groups on 5th day.2.The positive expression of HO-1 and TNF-?coincided with the change of the water content in groups of WB,PRBC and LRBC.Conclu- sions In rat model of TICH,RBC plays an important role in delayed brain edema formation(3 days after injury),but has no influence at early stage(1 day after injury).The mechanisms of delayed brain edema involves RBC breakdown and inflammation reaction.
