Three tricyclic [6,5,7] and six tetracyclic [6,5,5,5] novel indole alkaloids were synthesized and evaluated on triglyceride inhibitory activities for the first time. Among them, compound 4c showed the most potent activity with IC₅₀ value of 6.35 μmol·L^-1. Meanwhile, compound 4c also exhibited a good safety profile at the cellular level. Preliminary mechanism study indicated that 4c might increase intracellular lipid metabolism by activating AMPK. These results provide a novel family of lead compounds for the discovery of anti-NAFLD candidates.

Objective To investigate the effect of laparoscopic ultrasonography assistance in minimally invasive surgery for uterine leiomyoma patients and provide scientific basis for reducing the recurrence rate of uterine leiomyoma. Methods 156 cases of uterine leiomyoma from January 2011 to June 2014 were divided into control group and observation group according to the digital table method, 78 cases in each. The control group were treated with conventional laparoscopic surgery, while the observation group with laparoscopic ultrasonography assistance, then compare the postoperative residue, recurrence in 12 months at different time points and the number of fibroids diameter, analyze the relationship between number of uterine muscle tumor and residual recurrence. Results There were no significant differences in operation time, blood loss, length of hospital stay and anal exhaust time between the two groups. The proportion of patients in the observation group and the recurrence rate within 12 months were significantly lower than those in the control group, the number of uterine leiomyomas in the observation group was significantly lower than that in the control group at 3 months, 6 months, 9 months and 12 months after operation. The patients in the two groups were followed up for 3 months and 6 months the maximum diameter of uterine leiomyoma was not statistically significant, the observation group 9 months and 12 months after the maximum diameter of uterine fibroids was significantly lower than the control group, and the difference was statistically significant; with the patient's uterine muscle the number of residual tumor and the recurrence rate were significantly increased. When the number of uterine leiomyomas was 10 or more, the residual rate was 100.0％ and the recurrence rate was 80.0％. Conclusion Laparoscopic ultrasonography assistance in minimally invasive surgery for patients with uterine fibroids can effectively reduce the postoperative residual rate and recurrence rate, worthy of clinical promotion.

Group A rotavirus are the most frequently detected viral agent associated with the acute diarrhea in calves. In order to investigate the situation of rotavirus strains circulating in diary farms, a total of 117 fecal specimens were collected from diarrhea calves under 4 weeks-age on Yinluo diary farm in Daqing region in China from 2008 to 2009. Ten specimens were detected to be positive by a Rotavirus Group A Diagnostic Kit, which confirmed that the rotavirus was important viral agent associated with diarrhea in this diary farm. Based on the new classification system, G10P[11] genotype was determined in rotavirus positive samples. Sequence and Phylogenetic analysis indicated DQ-75 strain was introduced into our country with imported bovine.

Objective: To evaluate the effects of CYP2C19 genetic polymorphism on the plasma concentration of voriconazole in patients with hematological disease and the value of serial monitoring plasma concentrations in the treatment and prevention of invasive fungal disease (IFD). Methods: From January 2016 to December 2016, 65 hematological patients who received voriconazole intravenous administration for the treatment of invasive fungal disease were enrolled in this study. The population CYP2C19 polymorphism of voriconazole were performed using PCR-Pyrosequencing. The trough plasma concentrations of vriconazole (C_trough) was detected by ultra performance liquid chromatography tandem mass spectrometry. Results: Based on the genotype analysis, 65 subjects were identified as extensive metabolizers' group (30 cases) and poor metabolizers' group (35 cases). The C_trough of the 65 patients were detected for 169 times totally, and there was a significant difference of C_trough values between the two groups [0.98(0.38-2.08) mg/L vs 2.19(1.53-4.27) mg/L, z=10.286, P<0.001]. The medium of C_trough in 65 hematological patients were described. Lack of response to therapy was more frequent in patients with voriconazole levels <1.5 mg/L (50.0%) than in those with voriconazole levels >1.5 mg/L (20.5%) (P=0.052). And the risk of adverse events was more frequent in patients with voriconazole levels >5.5 mg/L (80.0%) than in those with voriconazole levels ≤5.5 mg/L (8.3%) (χ²=11.689, P=0.020). Conclusion: Patients with CYP2C19 wild-type phenotype are extensive metabolizers, their C_trough of voriconazole are significantly lower than patients with CYP2C19 non-wild-type phenotype (poor metabolizers). Appropriate concentrations of vriconazole can improve the efficacy and safety during treatment.

OBJECTIVETo study the effects of resveratrol on amino acid release in cultured astrocytes with stretch injury and explore its possible mechanism for central nervous system protection.

METHODSCultured rat astrocytes were treated with different concentrations of resveratrol for 12 h and the subsequent changes in Glu and Gln release and lactate dehydrogenase(LDH) leakage were examined after stretch injury.

RESULTSHigh-performance liquid chromatography showed that stretch injury increased Glu release from the astrocytes (P<0.05), and at the concentration of 1 micromol/L, resveratrol further increased Glu release (P<0.05), whereas at 100 micromol/L, resveratrol obviously inhibit Glu release (P<0.05). LDH leakage increased significantly after stretch injury of the astrocytes (P<0.05), and resveratrol acted to further increase LDH leakage at 1 micromol/L but inhibited LDH leakage at 100 micromol/L (P<0.05).

CONCLUSIONResveratrol can inhibit the release of Glu and LDH leakage from rat astrocytes to protect the cells from stretch injury.

Objective: To observe the effects of moxibustion on colonic inflammation, and the expressions of ubiquitin and nucleotide-binding oligomerization domain (Nod)-like receptor protein 3 (NLRP3) proteins in rats with ulcerative colitis (UC), and to explore the anti-inflammatory mechanism of moxibustion in the UC treatment. Methods: Clean grade male Sprague-Dawley (SD) rats were randomly divided into a normal group (NG), a model group (MG), a moxa-stick moxibustion group (MSMG) and a Western medicine group (WMG). UC model was prepared by freely drinking 35 g/L dextran sulfate sodium (DSS) solution. Bilateral Tianshu (ST 25) were selected for mild moxibustion treatment in the MSMG; mesalazine solution was intragastrically administrated in the WMG. Rats in the NG and MG were only grasped and fixed as in the MSMG without any treatment. After treatment, hematoxylin-eosin (HE) staining was performed to observe and score the colonic pathological damage under light microscope; immunofluorescence method was used to determine the expression of colonic ubiquitin protein; immunohistochemical method was used to detect the expressions of colonic interleukin (IL)-1β and NLRP3 proteins. Results: The colon tissue was severely injured, and the pathological score was significantly increased in the MG than in the NG (P<0.01), and the protein expressions of ubiquitin, NLRP3 and IL-1β in the colon were significantly increased (all P<0.01). Compared with the MG, the colonic damage was repaired, the inflammation and pathological scores were reduced, and the ubiquitin, NLRP3 and IL-1β protein expressions were decreased in the MSMG and WMG (all P<0.01). Correlation analysis revealed that the ubiquitin protein expression was correlated with the colonic pathological score and the NLRP3 protein expression (r=0.677, P<0.01; r=0.536, P<0.05). Conclusion: Moxibustion can down-regulate the protein expressions of ubiquitin, NLRP3 and IL-1β in the colon of UC rats, which may be one of the mechanisms to promote the repair of colonic inflammatory lesions and exert anti-inflammatory effects.

OBJECTIVEThe aim of this study is to investigate the self-reported prevalence and other epidemiological characteristics of allergic rhinitis from 11 cities throughout the mainland of China.

METHODSTelephone interviews were conducted in the two main municipalities (Beijing, Shanghai) and eight capital cities (Changsha, Changchun, Hangzhou, Guangzhou, Nanjing, Shenyang, Wuhan, Urumqi and Xi'an) of main provinces throughout the mainland of China after sampling target phone numbers by the approach of random digital dialing (RDD) via computer.

RESULTSIn total, the survey had sampled 684 blocks of telephone numbers in 11 cities, and dialed 119 319 telephone numbers. Of the 38 203 respondents, 4253 subjects reported allergic rhinitis, while the other 33 950 were screened negative in the telephone interviews. The self-reported prevalence of allergic rhinitis was lowest in Xi'an (8.0%), and highest in Urumqi (21.4%), with Nanjing having intermediate value (11.5%). The gender-adjusted prevalence ranged from 8.5% in Xi'an to 21.3% in Urumqi, while the age-adjusted prevalence of self-reported allergic rhinitis ranged from 8.7% in Beijing to 24.1% in Urumqi.

CONCLUSIONSThe study demonstrates that the self-reported prevalence of allergic rhinitis in 11 cities throughout the mainland of China has wide variations, and the strategy of prevention for allergic rhinitis should be conducted according to the epidemic features of it.

Abstract：Objective To predict the structure and function of sterol O⁃acyltransferase 1（SOAT1）related to hepatocellular carcinoma（HCC）by using bioinformatics tools，in order to understand its mechanism as the marker and therapeutic target of S⁃Ⅲ subtype. Methods The structure，function and protein interaction of SOAT1 were predicted and analyzed by using databases or softwares such as NCBI，STRING，Protscale，SignalP，TMHMM，PSORT，SOPMA，SWISS ⁃ MODEL， NetNGlyc，NetOGlyc，Netphos and ProtParam. Results The protein encoded by SOAT1 was a hydrophobic protein with good stability，which was a nonclassical pathway protein with 8 transmembrane regions，mainly distributed among the cell membrane. SOAT1 was expressed in many tissues，while most of them in the adrenal gland，which showed multiple phosphorylation sites and was mainly involved in the synthesis and catabolism of cholesterol. Conclusion Bioinformatics analysis of structure and function of SOAT1 showed that SOAT1 lipid synthesis and catabolism pathways played an important role，and lipid expression was closely related to the development of cancer，indicating that the treatment of HCC may be achieved by regulating the expression of SOAT1 gene.
