BACKGROUND:Proinflammatory transcription factors and inflammatory factors play an important role in the occurrence of alcoholic liver disease. However, early growth response factor 1 is one of the key factors of starting inflammation. OBJECTIVE: To investigate and analyze the effects of silymarin on early growth response factor1 in rat models of alcoholic fatty liver. METHODS:The rat models were established using the methods of feeding with high fat diet and intragastricaly administering alcohol, in total 8 weeks. Silymarin intervention at high and low doses (200,100 mg/kg) was given after each gavage. The normal group was set as comparison. RESULTS AND CONCLUSION:Serological indicator detection and hematoxylin-eosin staining results showed that compared with the model group, the body weight of rats was increased (P < 0.05); serum aspartate aminotransferase, alanine aminotransferase activity, early growth response factor 1 and tumor necrosis factor-α expression in the liver tissue were decreased (P < 0.05); pathological grading results were superior in the high-dose silymarin group to in the other groups (P < 0.01). The results confirm that high dose of silymarin can protect the liver function of rats, reduce the occurrence of liver function damage, which may be associated with the inhibition on the early growth response factor 1 in the body of rats, thereby reducing the tumor necrosis factor-α formation, but the specific mechanism remains to be further studied.

Objective To explore the anti-hyperuricemia activity of bergenin in the model of hyperuricemic mice induced by potassium oxonate. Methods 60 Kunming male mice were divided randomly into six groups, which were normal control group;hyperuricemic model group;and hyperuricemic groups with 20 , 40 , 60 mg/kg berge-nin, and 5 mg/kg allopurinol. Mice were orally administered once daily with 250 mg/kg potassium oxonate for 7 continuous days to create the model, and then three doses of bergenin and allopurinol were orally initiated on the day 1 h after potassium oxonate was given, separately. Serum uric acid, creatinine and urea nitrogon levels, as well as urinary uric acid and creatinine levels were measured. mRNA and protein expression levels of mouse kidney u-rate transporter 1(URAT1), and glucose transporter 9(GLUT9) were also determined. Results Compared with hyperuricemic model group, bergenin significantly reduced serum uric acid, creatinine and urea nitrogon levels, in-creased 24 h uric acid and creatinine excretion, and fractional excretion of uric acid in hyperuricemic mice;mRNA and protein levels of mURAT1 and mGLUT9 were also markedly down-regulated. Conclusion Anti-hyperuricemia effect of bergenin is attributed to the enhancement of uric acid excretion and reversion of mouse urate transporters o-ver-expression.

Objective To investigate hepatitis B virus surface antign (HBsAg) quantitative value quantitatively in serum of chronic hepatitis B virus (HBV) infection patients with different clinical stages,at the same time,to explore the correlation between HBV DNA,patient's age and HBsAg quantitative values.Methods Collected 774 cases without antiviral treatment of chronic HBV infection from our hospital,according to the clinical features,divided cases into six groups:chronic HBV carrier group (102 cases),inactive HBsAg carrier group (211 cases),hepativis B virus e antigen (HBeAg) positive chronic hepatitis B group (236 cases),HBeAg negative chronic hepatitis B group (114 cases),HBeAg positive hepatitis B cirrhosis group (52 cases),HBeAg negative hepatitis B cirrhosis group (59 cases).Used chemiluminescence immunoassay particles analysis to determine HBsAg quantitative value in serum in patients,used real-time fluorescent quantitative polymerase chain reaction method to determine HBV DNA quantitative value in patients,and then compared differences among groups.Results HBsAg quantitative value from high to low respectively were chronic HBV cartier group,HBeAg positive chronic hepatitis B group,HBeAg negative chronic hepatitis B group,inactive HBsAg carrier group,HBeAg negative hepatitis B cirrhosis group,HBeAg positive hepatitis Bcirrhosis group,the median quantitative value of HBsAg were [7.80 (6.69-8.32),7.11 (5.42-8.27),6.57 (5.66-7.53),6.38 (4.39-7.40),6.22 (4.84-6.91),6.13 (5.48-7.01)] ; positive correlation was found between HBsAg quantitative value and HBV DNA in HBeAg positive chronic hepatitis B group and HBeAg negative chronic hepatitis B group (r =0.714,0.390,P ＜ 0.01); negative correlation was found between HBsAg quantitative value and age in chronic HBV infection(r =-0.416,P ＜ 0.01) ; Monitored HBsAg quantitative value of inactive HBsAg carriers after the age 40 had important clinical value.Conclusions HBsAg quantitative value is different in the various phases of chronic HBV infection.HBV DNA levels and age are related with HBsAg quantitative value.HBsAg quantitative value should be monitored in inactive HBsAg carriers after the age 40.

The efficacy of hematological tumor drugs has shown inter-patient variability. Pharmacogenomics focuses on gene polymorphisms of drug metabolizing enzymes, drug transporters and therapeutic targets and its impact on pharmacokinetics (PK)/pharmacodynamics (PD). Initial dose and adverse reaction can be predicted based on inherited gene polymorphisms, and therapeutic drug monitoring (TDM) also helps to adjust drug dosage in the course of treatment. Thus can achieve rational drug use and personalized medicine, and improve the efficacy and reduce the incidence of adverse drug reactions. This article will introduce the relevant research progress in recent years, and the concept of personalized medication fingerprints is proposed.

The connotations of "du-fu" and "Sanli" in "Sanli acupoint for du-fu diseases" are discussed in this paper, which can provide theoretical foundation for the clinical application of "Sanli acupoint for du-fu diseases". Based on ancient literature combined with related theories in the Huangdi Neijing (Yellow Emperor's Canon of Internal Classic), a deep discussion is performed through the relationship between Zusanli (ST 36) and stomach, indication and mechanism of Zusanli (ST 36) on du-fu diseases and comparison between Zusanli (ST 36) and Shousanli (LI 10). It is believed that "du" should be pronounced as "dŭ", meaning stomach, and it indicates that Zusanli (ST 36) is closely related to stomach and spleen when it is used for du-fu diseases; "fu" means abdomen area, including liver-gallbladder, spleen, stomach-intestine, kidney, uterus, triple energizer; "sanli' means exclusively the acupoint of Zusanli (ST 36).

Alternative polyadenylation ( APA) is a widespread phenomenon and an important layer of gene regulation . APA contributes to the complexity of the transcriptome by allowing a single gene to encode multiple mRNA isoforms that dif -fer either in their coding sequence or in their 3′untranslated regions (3′UTR).The length of the 3′UTR can affect the sta-bility, localization and efficiency of the messenger RNAs ( mRNAs) by altering binding sites of RNA binding proteins or mi-croRNAs(miRNAs).The polyadenylation process , mechanisms governing APA and biological consequences resulting from APA are only starting to be deciphered .Here, we review the research progress in APA .

Objective To observe the significance of tumor abnormal protein (TAP)in the therapeutic monitoring of non-small cell lung cancer (NSCLC).Methods Peripheral blood from 30 NSCLC patients were collected to make smears at the moment of pre-treatment,half a month,one month,3 months and 6 months after therapy.TAP was detected by coacervation method.The maximum area of condense was applied to estimate the level of TAP.Thirty healthy subj ects were chose as con-trol group.Results The positive rate of TAP in NSCLC patients was 86.67%,and 3.33% of healthy subjects were positive in TAP.The difference was statistically significant (χ2=140.3,P<0.01).The condense area of TAP in patients withⅢ~Ⅳ stage of NSCLC [411(89,562)mm2]was significantly higher than those withⅠ~Ⅱ stage NSCLC [267(31,407)mm2]. The condense areas in both of two groups went down after treatment.A significant difference of condense area appeared inⅠ~Ⅱ stage of NSCLC patients a month after therapy as well as Ⅲ~Ⅳ stage of NSCLC patients half a month after treat-ment.The condense areas went to their lowest level 3 months after therapy.ForⅠ~Ⅱ stage patients,the condense area fell to 21% compared to that before treatment,but for patients withⅢ~Ⅳ stage of NSCLC,37% of pre-treatment condense ar-ea were detected.TheⅠ~Ⅱ stage of NSCLC patients had a greater decrease in condense area of TAP than theⅢ~Ⅳ stage patients by 3 months after treatment (χ2=6.22,P<0.05).Conclusion Detection of TAP in peripheral blood had a high sensitivity for NSCLC,and is able to monitoring the treatment effect.

OBJECTIVE: To investigate the effect of electro-acupuncture (EA) at Fenglong (GV 16) on body weight, blood lipids, nitric oxide (NO) and endothelin (ET) in rats with hyperlipidemia (HLP). METHODS: Eighty Wistar rats were randomly divided into normal control group (fed normal diet), untreated group (fed a high-fat diet), EA-treated group (fed a high-fat diet plus EA therapy) and pravastatin-treated group (fed a high-fat diet plus pravastatin tablet). There were 20 rats in each group. The body weight and the blood content of total cholesterol (TC), triacylglycerol (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), NO the and ET of the rats in different groups were measured before experiment and after 30-day treatment. A modified method of cardiac puncture for blood sampling was used for blood collection. RESULTS: Compared with the normal control group, the body weight and the levels of TC, TG, LDL-C and ET in the untreated group were significantly elevated (P<0.01, P<0.05), while the levels of HDL-C and NO were obviously decreased (P<0.05). The body weight and the levels of TC, TG, LDL-C demonstrated significant reduction in pravastatin-treated group and EA-treated group as compared with the untreated group (P<0.01), and the NO content in pravastatin-treated group and EA-treated group was higher than that in the untreated group (P<0.01). Compared with the untreated group, HDL-C level was elevated significantly in pravastatin-treated group, while HDL-C level in EA-treated group was not changed significantly, and there was significant difference in the HDL-C level between pravastatin-treated group and EA-treated group (P<0.01). The level of ET was decreased obviously in pravastatin-treated group (P<0.05), while the level of ET in EA-treated group was not changed significantly (P>0.05). CONCLUSIONS: Both EA therapy and pravastatin have efficient regulation of body weight and the content of TC, TG, LDL-C and NO in HLP rats. To some extent, they are able to regulate the imbalance between ET and NO content under the condition of HLP. Western medicine such as pravastatin can regulate the HDL-C level in HLP rats, while the effect of EA therapy on regulation of the HDL-C level is limited.
