ABSTRACT
This manuscript aims to investigate the effects of resibufogenin on the proliferation, migration and invasion of human hepatocellular carcinoma cells and its related mechanisms. MTT assay was used to determine the inhibitory effect of resibufogenin on the growth of four hepatocellular carcinoma cells in vitro. Wound-healing assay and Transwell assay were used to evaluate the migration and invasion ability of resibufogenin on MHCC-97H cells. Western blot assay was used to detect the expression of migration and invasion related proteins in MHCC-97H cells treated with different concentrations of resibufogenin. The results showed that resibufogenin significantly inhibited the proliferation of hepatocellular carcinoma cells in vitro. The half maximal inhibitory concentration (IC50) values on MHCC-97H, HepG2, SK-Hep-1 and Huh-7 cells were 0.55 ± 0.06, 2.83 ± 0.24, 5.25 ± 0.49, 14.89 ± 2.28 μmol·L-1, respectively. Resibufogenin also suppressed the migration and invasion of MHCC-97H cells in a concentration-dependent manner. The protein expression of integrin α2, integrin α6, integrin β1, N-cadherin, matrix metalloproteinase 2 (MMP2) and transcription factor Twist in MHCC-97H cells were decreased significantly with the increase of the concentration of resibufogenin, while the protein expression of E-cadherin increased. In addition, we found that p-PI3K/PI3K and p-AKT/AKT ratios were significantly reduced after treatment with resibufogenin. In conclusion, resibufogenin can inhibit the proliferation, migration and invasion of hepatocellular carcinoma MHCC-97H cells in vitro, which is related to the regulation of intracellular migration and invasion protein expression and PI3K/AKT signaling pathway.

ABSTRACT
<p><b>Background</b>Treatment of myoclonic seizures in myoclonic epilepsy with ragged-red fibers (MERRFs) has been empirical and ineffective. Guideline on this disease is not available. Additional trials must be conducted to find more suitable treatments for it. In this study, the antimyoclonic effects of monotherapies, including levetiracetam (LEV), clonazepam (CZP), valproic acid (VPA), and topiramate (TPM) compared to combination therapy group with LEV and CZP on MERRF, were evaluated to find a more advantageous approach on the treatment of myoclonic seizures.</p><p><b>Methods</b>Treatments of myoclonic seizures with VPA, LEV, CZP, and TPM were reported as monotherapies in 17 MERRF patients from Qilu Hospital between 2003 and 2016, who were diagnosed through clinical data and genetic testing. After 1-4 months of follow-up (mean: 82.9 ± 28.1 days), 12 patients that exhibited poor responses to monotherapy were given a combined treatment consisting of LEV and CZP subsequently. The follow-up period was 4-144 months (mean: 66.3 ± 45.3 months), the effective rates of monotherapy group (17 patients) and combination therapy group (12 patients) were analyzed by Chi-square test.</p><p><b>Results</b>The m.8344 A>G mutation was detected in all patients. There were four patients with partial response (4/17, two in the CZP group and two in the LEV group), ten patients with stable disease (10/17, six in the CZP group, three in the LEV group, and one in the TPM group), and three patients with progressive disease (3/18, two in the VPA group and one in the TPM group). Twelve of the patients with LEV combined with CZP showed a positive effect and good tolerance (12/12), eight of them demonstrated improved cognition and coordination. There was a significant difference between the monotherapy group and combination therapy group in the efficacy of antimyoclonic seizures (χ = 13.7, P < 0.001).</p><p><b>Conclusions</b>LEV in combination with CZP is an efficient and safe treatment for myoclonic seizures in patients with this disease exhibiting the m.8344A>G mutation.</p>
ABSTRACT
Objective To compare the difference of transformation profile and transformation rate of tecomin by using two in vitro liver metabolism models. Methods Liver microsomes and liver S9 fraction models were employed to transform tecomin. HPLC was used to determine the contents of tecomin and its metabolites at the detecting wavelength of 254 nm. The gradient elution (0–6 min, 5％–40％ A; 6–9 min, 40％–50％ A; 9–11 min, 50％–5％ A) was carried out by using mobile phase of acetonitrile (A) - 1％ acetic acid (B) at a flow rate of 1 mL/min. Results Both models could transform tecomin into veratric acid; however, the metabolites obtained with liver S9 were more than those obtained with liver microsomes, and the transformation rate of the former was higher than that of the latter. Conclusion The liver S9 fraction can more efficiently transform esters than liver microsomes.

ABSTRACT
Objective To analyze the practicability of using ELISA kit for the detection of hepati-tis E virus antigen ( HEV-Ag) in plasma donations and Biomex HEV seroconversion panels. Methods The HEV-Ag positive samples were screened out from 36 340 donated blood plasma samples. Real-time fluores-cent PCR was performed for the detection of HEV RNA in HEV-Ag positive samples. The open reading frame 2 (ORF2) in HEV RNA was amplified by nested RT-PCR and the amplified products were confirmed by sequencing analysis. Phylogenetic tree was constructed for HEV genotyping. Five Biomex HEV serocon-version panels were used in this study for the detection of HEV-Ag, anti-HEV antibody and HEV RNA as well as the correlation analysis between HEV-Ag and HEV RNA. Results Twenty-six out of 36 340 plasma samples (0. 07%) were positive for HEV-Ag. Of the 26 samples, 25 samples were positive for HEV RNA as indicated by the results of nested RT-PCR and 23 positive samples were confirmed by sequencing analysis. The positive rate of HEV RNA in blood plasma donators was 1 ∶ 1 580 (0. 06%). There were 17 samples of genotype 1 (74%) and 6 samples of genotype 4 (26%) according to the phylogenetic tree analysis. All of the HEV-Ag positive samples were also positive for HEV RNA as indicated by the analysis of Biomex sero-conversion panels. HEV-Ag was consistent with the peak of the HEV RNA concentration. Conclusion A close relationship between HEV-Ag and HEV RNA was observed. HEV-Ag screening could be used as a measure to reduce the risk of HEV transmission by blood transfusion.
ABSTRACT
The actual efficacy of acupuncture on cerebral infarction was explored in clinical practice. The retro spective cohort study was adopted to investigate 344 cases via inpatient's medical cases. According to whether acupuncture was received or not, an acupuncture group (207 cases) and a non-acupuncture group (137 cases) were divided. The matching method, regression method and weighting method of propensity score (PS) were adopted, and the efficacy on muscle strength was taken as effect index so that the specific impacts of acupuncture were ex plored on the muscle strength in the patients of cerebral infarction. Before matching, COX regression model and Logistic regression model were used. And PS hierarchical regression, PS inverse probability weighting method (IPTW) and PS standardized mortality weighting method (SMRW) were applied to the analysis on the relationship between the muscle strengthen changes and the total effective rate in the two groups. It was found that the efficacy in the acupuncture group was better than that in the non-acupuncture group, indicating the significant difference (P<0.05). Meanwhile, the rehabilitation therapy also brought the obvious impacts on the efficacy evaluation (OR=2.737, P=0.0055). After PS matching, the Logistic regression model was used to analyze whether acupuncture or rehabilitation therapy impacted the total effective rate of muscle strength. The results showed that the efficacy was impacted apparently with the rehabilitation therapy involved (OR=2.930, P=0.0247). Without the rehabilitation effect considered, the efficacy in the acupuncture group was better potentially than that in the non-acupuncture group, but without significant difference (OR=2. 235, P=0,058 7). All of these indicate that on the basis of routine treatment, without the effect of rehabilitation therapy considered, acupuncture improves in tenden cy of the muscle strength of the patients with cerebral infarction. However, it is expected to increase the study medical cases for further verification.

ABSTRACT
BACKGROUND:With the development and improvement of liver transplantation technology, patients waiting for or undergoing liver transplantation have continued to increase in number. Due to their fears and concerns about post-transplantation rehabilitation, patients are under physical and mental stress, most of whom are shown to have a variety of mental disorders that affect rehabilitation. At present, mental problems of liver transplant patients are more concentrated in post-transplantation research, while patients waiting for liver transplantation do not get enough mental assessment and intervention. OBJECTIVE:To investigate the suitable mode of cognitive-behavioral therapy for liver transplant recipients waiting for donor liver and to evaluate the effect to improve patient’s physical and mental state. METHODS:Twelve liver transplant patients who underwent pre-transplantation assessment were randomly divided into experimental group and control group, each group with six cases. The control group received conventional treatment. The experimental group received cognitive-behavioral therapy in addition to conventional treatment. Self-rating anxiety scale (SAS) and vital signs were measured in the two groups on admission, 1 week and 3 weeks after admission. RESULTS AND CONCLUSION:The SAS score of the experimental group was lower than that of the control group at 1 and 3 weeks after admission, and SAS score decreased as the intervention extended. The systolic blood pressure of the experimental group was lower than that of the control group at 3 weeks after admission, but there was no significant difference in diastolic blood pressure between two groups. The heart rate of the experimental group was lower than that of the control group at 1 and 3 weeks after admission. The respiratory rate of the experimental group was lower than that of the control group at 3 weeks after admission. Cognitive-behavioral therapy can reduce the level of anxiety and keep vital signs stable with good feasibility and effectiveness in patients waiting for liver transplantation.
ABSTRACT
<p><b>BACKGROUND</b>Familial cerebral cavernous malformations (CCMs), characterized by hemorrhagic stroke, recurrent headache and epilepsy, are congenital vascular anomalies of the central nervous system. Familial CCMs is an autosomal dominant inherited disorder and three CCM genes have been identified. We report a Chinese family with CCMs and intend to explore clinical, pathological, magnetic resonance imaging (MRI) features and pathogenic gene mutation of this family.</p><p><b>METHODS</b>Totally 25 family members underwent brain MRI examination and clinical check. Two patients with surgical indications had surgical treatment and the specimens were subjected to histopathological and microstructural examination. In addition, polymerase chain reaction (PCR) and direct sequencing were performed with genomic DNA extracted from 25 family members' blood samples for mutation detection.</p><p><b>RESULTS</b>Brain MRI identified abnormal results in seven family members. All of them had multiple intracranial lesions and four cases had skin cavernous hemangioma. T2-weighted sequence showed that the lesions were typically characterized by an area of mixed signal intensity. Gradient-echo (GRE) sequence was more sensitive to find micro-cavernous hemangiomas. There was a wide range in the clinical manifestations as well as the age of onset in the family. The youngest patient was an 8-year-old boy with least intracranial lesions. Histopathological and microstructural examination showed that CCMs were typically discrete multi-sublobes of berry-like lesions, with hemorrhage in various stages of illness evolution. They were formed by abnormally enlarged sinusoids and the thin basement membranes. A novel T deletion mutation in exon 14 of CCM1 gene was identified by mutation detection in the seven patients. But unaffected members and healthy controls did not carry this mutation.</p><p><b>CONCLUSIONS</b>The clinical manifestations were heterogenic within this family. We identified a novel mutation (c.1396delT) was the disease-causing mutation for this family and extended the mutational spectrum of CCMs.</p>
