Drinking culture has high significance in both China and the world, whether in the entertainment sector or in social occasions; according to the World Health Organization's 2018 Global Alcohol and Health Report, about 3 million people died from excessive drinking in 2016, accounting for 5.3% of the total global deaths that year. Oxidative stress and inflammation are the most common pathological phenomena caused by alcohol abuse (Snyder et al., 2017). Scutellarin, a kind of flavonoid, is one of the main active ingredients extracted from breviscapine. It exerts anti-inflammatory, antioxidant, and vasodilation effects, and has been used to treat cardiovascular diseases and alcoholic liver injury. Although scutellarin can effectively alleviate multi-target organ injury induced by different forms of stimulation, its protective effect on alcoholic brain injury has not been well-defined. Therefore, the present study established an acute alcohol mice brain injury model to explore the effect of scutellarin on acute alcoholic brain injury. The study was carried out based on the targets of oxidative stress and inflammation, which is of great significance for the targeted therapy of clinical alcohol diseases.

OBJECTIVETo study the effect of water stress on the content of scutellarin and caffeate in Erigeron breviscaps.

METHODFv/Fm, N content, as well as the content of scutellarin and caffeate under three water grads were measured.

RESULT AND CONCLUSIONFv/Fm of the plant decreased significantly in 8% and 23% water treatment, that proved drought and waterlogging occurred. Under the two conditions, the contents of N were lower but the contents of active constituents were higher than those under 15% treatment. The results support the carbon-nutrient balance hypothesis and the "stress effect hypothesis" for the formation of geo-herbs.

OBJECTIVETo study the effect and mechanism of Ganbi decoction (GBD) in treating patients with antituberculotic agent caused liver injury (ATB-LI).

METHODSOne hundred and twenty-eight patients with ATB-LI were randomly assigned to the treated group (n = 66) and the control group (n = 62) with the envelop method. Meanwhile, 60 healthy persons were selected as the healthy control group. The treated group was treated by GBD one dose every day with the constituents modified depending on patients' symptoms, and the control group was treated with glucuronolactone tablets and inosine injection. One week was taken as one treatment course. The changes of clinical syndromes, physical signs, T-lymphycyte sub-groups and serum level of nitric oxide (NO) were observed before and after treatment and the recovery time of liver function was recorded. The outcome was compared with that in the healthy control group.

RESULTSIn the treated group, 28 patients (42.4%) were cured, 30 (45.5%) improved and 8 (12.1%) ineffectively cured, the total effective rate being 87.9% (58/66). In the control group, 17 patients (27.4%) were cured, 24 (38.7%) improved, and 21 (33.9%) ineffectively cured, the total effective rate being 66.1% (41/62). The total effective rate in the treated group was significantly higher than that in the control group (P < 0.05). Liver function was improved in both groups, recovery time in the treated group was 12.0 +/- 7.0 days, which was significantly shorter than that in the control group (16.0 +/- 8.0 days), showing significant difference between the two groups (P < 0.05). The levels of CD3, CD4 and CD8 were significantly higher and level of NO significantly lower in the two groups of patients than those in the healthy control group (P < 0.05), but these parameters were improved more significantly in the treated group after treatment, when compared with those before treatment or with those in the control group, all showing significant difference (P < 0.05).

CONCLUSIONGBD could prevent ATB-LI, and its mechanism could be by way of reducing NO production induced by endotoxin of macrophage and stimulating the proliferation of T-lymphycyte to elevate immunity.

OBJECTIVETo observe the effect of Scutellarin (Scu) on expressions of nicotinic acetylcholine receptor (nAChR) subunit protein and mRNA in dementia rats, and to study its possible mechanism on dementia.

METHODSForty-two Wistar rats were randomly divided into 5 groups, i.e., the normal control group (n=6), the sham-operative group (n=6), the memory deficit model group, the Scu treatment group (n=10), and the positive drug (piracetam) control group (n=10). The dementia rat model was established by bilateral ventricle injection with beta-amyloid peptide (Abeta)(25-35) and abdominal cavity injection with D-galactose. Rats in the Scu treatment group or the piracetam control group were treated with Scu or piracetam by gastrogavage. The learning and memory ability of rats were detected by Morris water maze test, nAChR alpha4, alpha7, and beta2 subunits at protein and mRNA levels were detected by Western blot and Real-time PCR respectively.

RESULTSCompared with the normal control group and the sham-operative group, the learning and memory ability decreased in rats of the model group (P<0.05). nAChR alpha4 and alpha7 subunit protein expressions were obviously lowered (P<0.05), but changes of beta2 were not obvious. No obvious change of mRNA expressions in all three nAChR subunits was seen (P>0.05). After treatment of Scu, the learning and memory ability was greatly improved, nAChRs alpha4 and alpha7 subunit protein expressions increased in rats with dementia (all P<0.05). No obvious change of mRNA expressions in all three nAChR subunits was seen (P>0.05). No obvious difference of each index was shown between the Scu treatment group and the positive drug (piracetam) control group.

CONCLUSIONSScutellarin could improve the learning and memory ability of dementia rats. Its mechanism might be associated with its up-regulation of nAChR expressions.

Evidence-based medicine is advocated by WHO and adopted by developed countries for many years. In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione. Evidence was provided for relevant sectors such as Ministry for Human Resources and Social Security of the People's Republic of China and National Health and Family Planning Commission of the People's Republic of China to select and renew the Essential Medicine List (EML), the new rural cooperative medical scheme in China (NRCMS) list or the reimbursement list of industrial injury insurance. A total of 189 patients with initial pulmonary tuberculosis were divided into four groups who took antituberculotics combined with Jian'ganle, Hugan Pian, glucuronolactone and reduced glutathione respectively. Their liver function profile including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (A) and globulin (G) were detected at admission as baseline and after treatment. The Jian'ganle group was compared with the three others by chi-square tests. In an aspect of maintaining bilirubin indexes normal, Jian'ganle was more efficacious than glucuronolactone. And Jian'ganle had a little more efficacy than reduced glutathione to maintain protein indexes normal as well. And the therapeutic regimen of antituberculotics combined with Jian'ganle was the best in treating tuberculosis and preventing DILI at the same time. The study showed that among the four hepatinicas which demonstrated similar prevention of DILI caused by antituberculotics, Jian'ganle has more advantages over the three others to some extent, which provides a reliable basis for health sectors to select and renew the EML, NRCMS List or the reimbursement list of industrial injury insurance.
