OBJECTIVE:
To detect whether Danlou Tablet (DLT) regulates the hypoxia-induced factor (HIF)-1α-angiopoietin-like 4 (Angptl4) mRNA signaling pathway and explore the role of DLT in treating chronic intermittent hypoxia (CIH)-induced dyslipidemia and arteriosclerosis.
METHODS:
The mature adipocytes were obtained from 3T3-L1 cell culturation and allocated into 8 groups including control groups (Groups 1 and 5, 0.1 mL of cell culture grade water); DLT groups (Groups 2 and 6, 0.1 mL of 1,000 µg/mL DLT submicron powder solution); dimethyloxalylglycine (DMOG) groups (Groups 3 and 7, DMOG and 0.1 mL of cell culture grade water); DMOG plus DLT groups (Groups 4 and 8, DMOG and 0.1 mL of 1,000 µg/mL DLT submicron powder solution). Groups 1-4 used mature adipocytes and groups 5-8 used HIF-1 α-siRNA lentivirus-transfected mature adipocytes. After 24-h treatment, real-time polymerase chain reaction and Western blot were employed to determine the mRNA and protein expression levels of HIF-1 α and Angptl4. In animal experiments, the CIH model in ApoE-/- mice was established. Sixteen mice were complete randomly divided into 4 groups including sham group, CIH model group [intermittent hypoxia and normal saline (2 mL/time) gavage once a day]; Angptl4 Ab group [intermittent hypoxia and Angptl4 antibody (30 mg/kg) intraperitoneally injected every week]; DLT group [intermittent hypoxia and DLT (250 mg/kg) once a day], 4 mice in each group. After 4-week treatment, enzyme linked immunosorbent assay was used to detect the expression levels of serum total cholesterol (TC) and triglyceride (TG). Hematoxylin-eosin and CD68 staining were used to observe the morphological properties of arterial plaques.
RESULTS:
Angptl4 expression was dependent on HIF-1 α, with a reduction in mRNA expression and no response in protein level to DMOG or DLT treatment in relation to siHIF-1 α -transfected cells. DLT inhibited HIF-1 α and Angptl4 mRNA expression (P<0.05 or P<0.01) and reduced HIF-1 α and Angptl4 protein expressions with DMOG in mature adipocytes (all P<0.01), as the effect on HIF-1 α protein also existed in the presence of siHIF-1 α (P<0.01). ApoE-/- mice treated with CIH had increased TG and TC levels (all P<0.01) and atherosclerotic plaque. Angptl4 antibody and DLT both reduce TG and TC levels (all P<0.01), as well as reducing atherosclerotic plaque areas, narrowing arterial wall thickness and alleviating atherosclerotic lesion symptoms to some extent.
CONCLUSION
DLT had positive effects in improving dyslipidemia and arteriosclerosis by inhibiting Angptl4 protein level through HIF-1 α-Angptl4 mRNA signaling pathway.

The transplants of the two-year-old Glycyrrhiza uralensis were subjected to four concentration of brassinolide (BR 0.1, 0.4, 0.7, 1.0 mg•L⁻¹) in July. The morphological characters ( plant height, stem diameter, nodes number, internode length and root length , root thick, root fresh weight and root dry weight ) were measured and seven kinds of chemical constituents (glycyrrhizic acid, liquiritin, isoliquiritin, liquiritigenin, isoliquiritigenin, liquiritin apioside, isoliquiritin apioside) were determined by HPLC with the aim of increasing sinter output and improving quality of G. uralensis. Then the long-term dynamic changes of these morphological characters and chemical compositions' content were analyzed. The results showed that morphological characters of plant height, stem diameter, root length , root thick, root fresh weight and root dry weight increased remarkably with the 0.7 mg•L⁻¹ BR stimulating 2 months later,the increase rates were: 15.09%,6.15%,16.52%,8.46%,21.90%,29.41%, respectively. The content of glycyrrhizic acid, liquiritin, isoliquiritin, liquiritigenin, liquiritin apioside, isoliquiritin apioside were increased 20.16%,45.31%,53.56%,27.66%,23.54%,8.46% with the 0.7 mg•L⁻¹ BR stimulating 2 months later. The best effects were achieved in 2 months after brassinolide stimulating. The conclusions prove that morphological characters and the main chemical constituents accumulation of G. uralensis could be effected by exogenous BR stimulation in certain case.

OBJECTIVETo observe the change in the number of antibodies of preneoplastic hepatocellular carcinoma (HCC) using early treatment by Compound Phyllanthus Urinaria L. (CPUL) on patients with preneoplastic hepatitis B virus (HBV)-associated HCC.
METHODSA total of 102 cirrhosis patients with regenerative or dysplastic nodules whose sera were tested positive for at least one of these six proteins (five up-regulated genes URG4, URG7, URG11, URG12 and URG19, and one down-regulated gene DRG2) were assigned randomly to two groups using continual random codes by SPSS software. Fifty-two patients were in the treatment group and 50 patients were in the control group. CPUL was used in the treatment group for 3 years, while the control group did not receive any treatment. The changes in HBV-DNA level, number of antibodies, and hepatocarcinogenesis occurred were observed. Patients who did not develop HCC were followed up for another 2 years.
RESULTSHBV-DNA levels decreased ⩾2log in 22.2% (10/45) of patients in the treatment group in contrast to only 5.0% (2/40) of patients in the control group (P=0.0228). The number of antibodies that were tested positive in the treatment group (1.08±1.01) was significantly lower compared with the control group (2.11±1.12) after 24 months of drug treatment (P<0.01). Both the positive rates of anti-URG11 (33/52) and anti-URG19 (31/52) were over 60% at baseline in the two groups, and were decreased to 48.1% (25/52) and 46.2% (24/52) respectively at 36 months of drug treatment, while the rates increased to 68.0% (34/50) and 66.0% (33/50) respectively (P=0.0417, P=0.0436) in the control group. The positive rate of anti-DRG2 was increased to 55.8% (29/52) at 36 months of drug treatment, while in the control group was decreased to 36.0% (18/50, P=0.0452). Among the 102 patients who developed HCC, 2 were in the treatment group and 9 were in the control group, meaning that a significant difference between the two groups (P=0.0212). In 11 patients who developed HCC, anti-URG11 and anti-URG19 were always positive, while anti-DRG2 was negative. Patients newly developing HCC were 6 (20.0%) in the control group, and only one (2.5%) in the treatment group (P=0.0441) during 2-year follow-up after the end of the treatment.
CONCLUSIONSAnti-URG11, anti-URG19 and anti-DRG2 could be used as early markers in the prediction of the therapeutic efficacy of CPUL in treating preneoplastic HCC. CPUL is useful in preventing or delaying the development of HBV-associated cirrhosis to HCC.

OBJECTIVETo establish a novel and useful rabbit model of lumbar disc degeneration using microinjection of fibronectin fragment (Fn-f).
METHODSThirty-two New Zealand white rabbits underwent injection of N-terminal 30 kDa Fn-f (experimental group) or phosphate buffered saline (PBS) (control group) into the central region of L1-2, L2-3, L3-4, L4-5 discs using a 32-gauge microsyringe. Two rabbits (blank group) with no treatments were sacrificed to examine the proteoglycan synthesis of neucleus pulposus (NP) using (35)S-sulfate incorporation assay. At the 4-, 8-, 12-, and 16-week time points, the discs were examined histologically, radiographically, and with proteoglycan synthesis.
RESULTSHistology demonstrated a progressive loss of the cell numbers in NP and architecture destruction in NP and anulus fibrosus (AF) in Fn-f-injected discs over the 16-week study period. The NP regions in Fn-f-injected discs shrinked distinctly after the 4-week time point, and were not discernible with the inner AF by the 16-week time point. Protoglycan synthesis in Fn-f-injected discs decreased progressively (F = 263.241, P = 0.000). At each time point, the Fn-f-injected discs showed significantly decreased proteoglycan synthesis compared with controls (t = -27.010 - -2.833, P < 0.05). The DHI% of the Fn-f-injected discs at the 4-, 8-, 12-, and 16-week time points were 96.5% ± 1.7%, 85.6% ± 3.8%, 77.2% ± 3.5% and 65.5% ± 5.6%, respectively. Comparing with the DHI% of PBS-injected discs (97.4% ± 1.2%), the Fn-f-injected discs exihibited no significant differences in disc heights at the 4-week time point (P > 0.05), but significant decreases in disc heights at the 8-, 12-, and 16-week time points (t = -21.225 - -10.795, P < 0.01). Apparent anterior osteophytes formed at the 12-week time point and enlarged remarkablely by the 16-week time point in the experimental spines.
CONCLUSIONSFn-f can induce a progressively degenerative process in rabbit discs which is ethical, cost-effective, reproducible, and consistent with the spontaneous degeneration in human. And it seem to be a novel and useful model for the study of disc degeneration at the molecular level.

OBJECTIVETo analyze the incidence and survival rates of primary liver cancer (PLC) among residents in Yangpu district of Shanghai.
METHODSA total of 9 730 736 permanent residents (male 4 996 390 and female 4 734 346) of Yangpu district in Shanghai were recruited in the study between year 2002 and 2010; among whom 2726 PLC cases were diagnosed and 2427 death cases were certified. The incidence and mortality of PLC were calculated under the analysis of the new PLC cases and death cases between year 2002 and 2010. The rates were standardized by the demographic composition developed in the Fifth Nationwide Census in year 2000, in order to analyze the survival condition of PLC patients and explore the prognosis of surgical excision treatment.
RESULTSAmong the new PLC cases between year 2002 and 2010, 1966 cases were male, whose average age of onset was 59.81; while 760 cases were female, whose average age of onset was 68.93. The crude incidence rate was 39.35/100 000 in male, which was higher than it in female, as 16.05/100 000. The difference showed statistical significance (U = 7.32, P < 0.01). The standardized incidence rates were 21.98/100 000 and 6.96/100 000 in male and female, respectively. The difference showed statistical significance (U = 221.76, P < 0.01). There were 2427 PLC death cases in total, including 1734 male death cases and 693 female death cases. The crude mortality rate was 34.71/100 000 in male and 14.64/100 000 in female, whose difference were statistically significant (U = 6.68, P < 0.01). The standardized mortality rate was 19.16/100 000 in male and 6.06/100 000 in female, whose difference were statistically significant (U = 207.18, P < 0.01). The incidence and mortality rates both increased apparently since males aging over 35 and females over 45. The 1 - 5 year survival rates of PLC patients were 33.95%, 23.11%, 17.04%, 14.42% and 12.29%, respectively. In the surgical excision treatment group (321 cases), the 1 - 5 year survival rates were separately 66.78%, 52.87%, 41.88%, 33.57% and 32.64%; while in the non-surgical treatment group (2405 cases), the 1 - 5 year survival rates were separately 29.04%, 18.58%, 13.30%, 11.16% and 9.01%. The differences in 1 - 5 year survival rates between surgical and non-surgical groups all showed statistical significance (U = 12.78, 10.52, 8.28, 5.56 and 5.12, respectively, P < 0.01).
CONCLUSIONThe incidence of PLC was close to its mortality in Yangpu district of Shanghai. The male incidence and mortality rates were significantly higher than female corresponding rates. The surgical excision treatment could improve the prognosis of PLC.
