Ganoderma lingzhi is a well-known source of natural fungal medicines which has been given for the treatment of several diseases. China is one of the major commercial producers of Ganoderma mushroom worldwide. However, with the expansion of the commercial cultivation, the occurrence of the fungal diseases on G. lingzhi has also been increased. The green mold disease symptoms were observed in the cultivation base of G. lingzhi in Zuojia Town, Jilin City, Jilin Province, China, causing the basidiomes to be rotten and withered, and the green mycelium layer generated gradually. The pathogenicity tests showed the same symptoms as appeared naturally in Zuojia mushroom base. Morphology characters revealed conidia green, ellipsoid, globose, 2.56–4.83 × 2.09–4.22 μm, length-width ratio was 1.1–1.2 (n = 10). Conidiophores trichoderma-like, often asymmetry, branches solitary, paired or in whorls of 3 phialides formed solitary, paired or in whorl, variable in shape, lageniform, sometimes ampulliform or subulate. While using molecular methodology, comparing with the sequences of Trichoderma hengshanicum from GenBank, the analyzed sequence showed 97.32% homology with the RPB2 sequences, 100% with the TEF1-α sequences. A fungus isolated from the diseased tissues was identified based on morphology and molecular studies as T. hengshanicum. This is the first report of T. hengshanicum causing the green mold disease of G. lingzhi in China.

Objective To reveal the mechanism of action of AS-Ⅳ on HepG2 cells based on molecular dynamics simulation and experimental evaluation. Methods We constructed a "drug-disease" network pharmacological map, analyzed the core genes of astragaloside Ⅳ (AS-Ⅳ) in HCC, screened key signaling pathways, and established a "drug-target" molecular dynamics model. In vitro assay was used to detect migration, proliferation and invasion abilities. Flow cytometry and qRT-PCR were used to detect the effect of AS-Ⅳ on the cell cycle and apoptosis, and the expression of core gene of HepG2. Results The core target of AS-Ⅳ acting on HCC was VEGFA. Compared with the control group, the high concentration of AS-Ⅳ significantly inhibited the migration, invasion and proliferation of HepG2 cells, blocked the metastasis of HepG2 cells from G₁ to G₂ phase, promoted their apoptosis, down-regulated VEGFA expression and up-regulated TGF-β1 expression. Conclusion AS-Ⅳ may inhibit the proliferation of hepatocellular carcinoma cells through multi-target and multi-pathway.

Objective: To explore the efficacy and safety of chimeric antigen receptor T (CAR-T) cells in the treatment of central nervous system leukemia (CNSL). Methods: Two leukemia patients with CNSL were treated with CD19-CAR-T cells. The process and results of the entire treatment is reported and related literature review is conducted. Results: The patients were diagnosed as acute myeloid leukemia (AML)-M₂ with B lymphoid antigen expression and B cell acute lymphoblastic leukemia(B-ALL) by morphology and immunophenotype assay. The immunophenotype was consistent with the abnormal manifestations of AML-M₂ and B-ALL. Their clinical manifestations and laboratory tests met the diagnostic criteria of CNSL. The diagnosis was clear and the two patients were treated with CD19-CAR-T cell immunotherapy. Central nervous system symptoms were relieved. The imaging abnormalities of patient one has disappeared but cytokines release syndrome (CRS) occurred during the treatment. Cerebrospinal fluid of patient two was negative and no obvious CRS reaction was found. Conclusions CAR-T cell immunotherapy is likely to induce the remission of CNSL and improve the prognosis.

Objective: To describe the post competency level and standardized training of new nurses in Guangzhou tertiary hospitals, and to explore the correlation between them. Methods: By using the questionnaire method, 525 new nurses from 8 tertiary hospitals in Guangzhou were surveyed in June 2016 by convenience sampling, using the general information questionnaire, nursing competency questionnaire and standardized training status questionnaire of new nurses in Guangzhou tertiary hospitals. Results: The competency level of new nurses in Guangzhou tertiary hospitals was 333.53±46.96. The scores of standardized training level were 131.43±23.20. The scores of training management level, training content level and nurses′ belief level were 28.30±5.49, 59.07±14.80, 44.06±2.91. Competency level was positively correlated with standardized training level and each dimension with statistical significance (r=0.099-0.132, P<0.05). Conclusions The post competence of new nurses in Guangzhou tertiary hospitals is at the middle level, and the post competence of new nurses is positively correlated with the level of standardized training. Improving the level of standardized training of new nurses is helpful to enhance the post competence of new nurses. The level of standardized training management, management content and nurse belief can improve the post competence of new nurses.

BACKGROUND:Alzheimer's disease is a degenerative neurological disorder characterized primarily by cognitive impairment.Acupuncture is a kind of traditional Chinese medicine therapy for treating Alzheimer's disease,but its mechanism is not yet clear. OBJECTIVE:To observe the effects of electroacupuncture with"Zhi San Zhen"on the Notch signaling pathway,β-amyloid protein(Aβ)and synaptic plasticity in 5xFAD mice. METHODS:Sixteen male,6-month-old 5xFAD mice,SPF-grade,were randomly divided into the electroacupuncture with"Zhi San Zhen"group(electroacupuncture group)and the model group,with eight mice in each group.Eight SPF-grade,male,6-month-old C57BL/6 mice were used as the wild control(wild)group.The electroacupuncture group received electroacupuncture with"Zhi San Zhen"intervention,5 times a week for 4 consecutive weeks.The model group and the wild group did not receive electroacupuncture intervention.The Morris water maze was used to preliminarily assess their learning and memory abilities.Thioflavin S staining was performed to detect Aβ plaque deposition.Western blot and real-time quantitative polymerase chain reaction(RT-qPCR)were used to measure the expression levels of transmembrane receptor protein Notch-1,Notch 1 intracellular domain(NICD),hairy and enhancer of split 1(Hes 1),hairy and enhancer of split 5(Hes 5),synaptophysin(SYN),postsynaptic density protein-95(PSD-95),and Aβ. RESULTS AND CONCLUSION:Compared with the model group,the wild group and the electroacupuncture group showed shortened escape latency,increased platform crossing times,and longer target quadrant dwell time(P<0.05).Compared with the wild group,the model group had significantly increased deposition of Aβ plaques,while electroacupuncture with"Zhi San Zhen"inhibited the deposition of Aβ plaques in the hippocampus of 5xFAD mice(P<0.05).Compared with the wild group,the model group had decreased mRNA levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue of mice,and increased mRNA levels of Aβ(P<0.05).Electroacupuncture with"Zhi San Zhen"increased the mRNA levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue,and decreased the mRNA level of Aβ(P<0.05).Compared with the Wild group,the model group had decreased protein expression levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5 in the hippocampal tissue of mice,and increased protein expression levels of Aβ(P<0.05).Electroacupuncture with"Zhi San Zhen"upregulated the protein expression levels of SYN,PSD-95,Notch 1,NICD,Hes 1,and Hes 5,and inhibited the protein expression of Aβ(P<0.05).To conclude,electroacupuncture with"Zhi San Zhen"can improve the learning and memory abilities of 5xFAD mice,possibly by inhibiting the deposition of Aβ protein and activating the Notch signaling pathway in the hippocampus to enhance synaptic plasticity.

The correspondence between prescription and syndrome is the advantage and characteristic of traditional Chinese medicine(TCM)treatment.However,the pathogenesis of clinical diseases is complex and the condition is changeable,and the clinical application is difficult to achieve the maximum effect under the existing cognition of the correspondence between prescription and syndrome.In this paper,the five categories of physiological characteristics,pathological characteristics,constitution,syndrome,and disease of the longitudinal classification of"TCM state"are introduced into the correspondence of prescription and syndrome.Under the vertical perspective of"TCM state",the theoretical connotation of the correspondence between prescription and syndrome is interpreted as"correspondence between prescription and state",namely correspondence of"prescription-physiological characteristics",correspondence of"prescription-pathological characteristics",correspondence of"prescription-constitution",correspondence of"prescription-syndrome",and correspondence of"prescription-disease".It is hoped to accurately grasp the corresponding connotation of the correspondence between prescription and syndrome,in order to deepen the clinical thinking mode of TCM.

Objective: To investigate the expression of circular RNA hsa_circ_0128298 in hepatocellular harcinoma (HCC) and evaluate its function in the growth process of HCC. Methods: qPCR was used to detect the expressions of hsa_circ_0128298 in 50 HCC tissues, corresponding paracancerous tissues and HCC cells. The effects of hsa_circ_0128298 on HCC growth was analyzed by CCK-8 kit, flow cytometry and western blot assays. The values of hsa_circ_0128298 for the diagnosis and prognosis of HCC were assessed by ROC curve and survival curve analyses. Results: Compared with the paracancerous tissues, the expression of hsa_circ_0128298 was significantly increased in HCC tissues ( U =846.0， P =0.005). The area under ROC curve (AUCROC) was 0.661, 95% confidence interval ( CI ) was 0.560 to 0.753, sensitivity was 80.0% and specificity was 50.0%. HCC patients with high expression of hsa_circ_0128298 displayed less overall survival time than those with low expression of hsa_circ_0128298 ( χ 2=6.294, P =0.012). RNA interference of hsa_circ_0128298 (si-hsa_circ_0128298) significantly inhibited HCC cell proliferation and induced cell cycle arrest at G0/G1, and also induced mRNA upregulation and protein expression of cyclin p21. Meanwhile，si-p21 partially reversed the proliferation inhibition and cell cycle arrest of HCC cells induced by si-hsa_circ_0128298, and restore its growth and proliferation potential. Conclusion The highly expressed hsa_circ_0128298 in HCC could promote the growth of HCC by regulating the expression of p21 and promise to be a new target for diagnosis and treatment of HCC.
