Toxoplasma gondii infection is widespread worldwide, not only posing a serious threat to human food safety and animal husbandry, but also endangering human health. The selectivity index was employed to measure anti-T. gondii activity. Hederagenin (HE) exhibited potent anti-T. gondii activity and low cytotoxicity. For this reason, HE was selected for in vivo experiments. HE showed 64.8%±13.1% inhibition for peritoneal tachyzoites in mice, higher than spiramycin 56.8%±6.0%. Biochemical parameters such as alanine aminotransferase, aspartate aminotransferase, glutathione, and malondialdehyde, illustrated that HE was a good inhibitor of T. gondii in vivo. This compound was also effective in relieving T. gondii-induced liver damage. Collectively, it was demonstrated that HE had potential as an anti-T. gondii agent.

BACKGROUND:
Catheter ablation is effective in restoring sinus rhythm and left atrial appendage closure (LAAC) is increasingly used for stroke prevention in patients with atrial fibrillation (AF). We aimed to observe the feasibility and safety of performing AF ablation and LAAC in a single (one-stop) procedure.
METHODS:
Consecutive AF patients who underwent the combined procedure of AF ablation and LAAC with WATCHMAN device between March 2017 and September 2018 were prospectively enrolled. Baseline and intra-procedural parameters were evaluated. Three-month and subsequent 1-year follow-up were performed in all and earlier-enrolled subjects, respectively.
RESULTS:
A total of 178 AF patients (94 males, 68.9 ± 8.1 years) underwent the one-stop procedure with CHA2DS2-VASc score 3.3 ± 1.5 and HAS-BLED score 1.6 ± 1.0, respectively. Pulmonary vein isolation was achieved in all patients while additional linear ablation was applied if the operator deemed necessary, yielding immediate ablation success rate of 98.9% (176/178). In the subsequent LAAC, satisfactory seal (residual leak <5 mm) was achieved in all patients. One stroke and four cardiac perforations occurred peri-operatively. At 3-month follow-up, sinus rhythm and satisfactory seal were maintained in 153/178 (86.0%) and 178/178 (100%) patients, respectively. One stroke and one delayed cardiac tamponade occurred, while no device-related thrombus or device migration was observed. During the 1-year follow-up for the earlier enrolled subjects, 52/72 (72.2%) of the patients maintained sinus rhythm. There was no stroke or systemic embolism observed.
CONCLUSION
Combining catheter ablation and LAAC in a single procedure can be successfully and safely performed in non-valvular AF patients of Chinese population.

This study aims to establish a combinative method based on fingerprint,assay of multi-component and chemometrics for quality evaluation of Magnoliae Officinalis Cortex. Twenty batches of samples were determined by UPLC and a common mode of fingerprint was established. The similarities between fingerprints of 20 batches of samples were over 0. 90 and the common mode were evaluated. Eight components were identified as syringing, magnocurarine, magnoflorine, magnoloside B, magnoloside A, honokiol,magnolol,and piperitylmagnolol by comparison with reference substances and their content in samples were simultaneously determined.Based on the results,the fingerprint had good consistency between the same origin and minor diversity between the different sources.Piperitylmagnolol and peak 13 could be used as a distinction with the different sources. According to content of 8 components,Fisher discriminant analysis model was established and different source sample was classified pursuant to the discriminant fraction. It is indicated that simultaneous quantification of multi components coupled with chemometrics analysis could be a well-acceptable strategy to identify and evaluate the quality of Magnoliae Officinalis Cortex.

OBJECTIVETo observe the efficacy of ursodeoxycholic acid (UDCA) combined with glucocorticoids in the treatment of autoimmune hepatitis-primary biliary cirrhosis (AIH-PBC) overlap syndrome.
METHODS19 patients with AIH-PBC overlap syndrome were divided randomly into two groups: initiate combined group and initiate UDCA-monotherapy group. Biochemical responses and pathological features before and after treatment were analyzed retrospectively with student's t test, Wilcoxon rank sum test and Fisher's exact method.
RESULTSIn the initiate combination group, biochemical responses in terms of AIH features (ALT decline to normal, IgG is less than or equal to 16 g/L) and PBC features (ALP decline ≥ 40% or to normal) were achieved. In UDCA-monotherapy group, no statistical difference existed in biochemical responses before adding glucocorticoids, whereas the levels of ALT, AST, GLB and IgG decreased significantly when combined with glucocorticoids. No statistical difference of rates of biochemical responses eixted between the two groups, whereas variance could be seen in different pathological stages. Alleviation of inflammatory infiltration after therapy appeared in 3 patients.
CONCLUSIONCombination therapy of UDCA with glucocorticoids could be suitable for AIH-PBC overlap syndrome. Early treatment is of benefit for achieving better biochemical response and pathological improvement.

OBJECTIVETo explore the mechanism of the eye-acupuncture for treatment of acute cerebral ischemia-reperfusion injury.
METHODSThirty-two healthy SD rats were randomly divided into a normal group, a sham operation group, a model group and an eye-acupuncture group, 8 rats in each group. The rat model of cerebral ischemia-reperfusion was established with thread occlusion method in the model group and the eye-acupuncture group. The eye-acupuncture group was treated by eye-acupuncture at "liver region", "upper energizer area", "lower energizer area" and "kidney region" for 20 min immediately after reperfusion and at 30 min before sampling. No treatment was done in the normal group and the sham operation group, and no thread occlusion was performed in the sham operation group. The Neurologic impairment was scored and the methods of immunohistochemistry staining, western-blotting and real-time fluorescent quantitation polymerase chain reaction (RQ-PCR) were taken to detect the expression of the aquaporin protein 4 (AQP4) and its mRNA in cerebral cortex after reperfusion for 3 hours.
RESULTSThe neurologic impairment score of 1.50 +/- 0.54 in the eye-acupuncture group was significant lower than 2.63 +/- 0.92 in the model group (P < 0.01). The expression of the AQP4 protein by immunohistochemistry and western-blot respectively were 116.33 +/- 10.24 and 0.53 +/- 0.04 in the normal group, 118.97 +/- 12.72 and 0.55 +/- 0.07 in the sham operation group, and 129.30 +/- 18.36 and 0.67 +/- 0.08 in the eye-acupuncture group, with statistical significance compared to 150.88 +/- 15.82 and 0.94 +/- 0.04 in the model group (all P < 0.01), and there were significant differences between the eye-acupuncture group and the normal group (both P < 0.01). The tendency in the expression of AQP4 protein and its mRNA in all the group were almost the same.
CONCLUSIONThe eye-acupuncture therapy can relieve the cerebral ischemia-reperfusion injury and the protective mechanism is related to the downregulation of the cerebral AQP4 expression.

OBJECTIVETo assess the therapeutic effect of primary biliary cirrhosis(PBC) in different stages with ursodeoxycholic acid (UDCA).
METHODS91 patients with PBC were divided into 4 periods based on levels of liver test and symptoms. Clinical manifestations, biochemical changes and pathological changes were observed for 2 years on UDCA therapy.
RESULTSThe levels of alkaline phosphatase (ALP) and glutamyltranspetidase (GGT) at the second PBC period were declined by 51.9% and 67.3% respectively after a 6-month UDCA therapy. The biochemical responses were 81.25% (Paris criteria) and 93.75% (Barcelona criteria). The levels of ALP and GGT at the third PBC period were declined by 48.8% and 46.6% after 6 months of UDCA therapy, and the biochemical responses were 36.84% (Paris criteria) and 57.89% (Barcelona criteria). Symptoms like fatigue, pruritus and jaundice after UDCA therapy were better than before. Same results also appeared at the fourth period. 11 patients in different periods underwent pathological examinations before and after UDCA therapy and no progression found in the first and the second periods, however difference found in the third and the fourth periods with the lymphocyte infiltration was less than before UDCA treatment.
CONCLUSIONGood biochemical responds appear in patients at the second, third and forth periods after UDCA therapy, in which the second period is best. Symptoms could be improved after UDCA treatment. Early UDCA therapy is benefit for slowing down the progression of liver pathology.
