Objective The physiological and biochemical changes were studied during the Panax notoginseng′s fruit development.Methods Dynamic changes of fruits size,fresh and dry weight,moisture content and soluble sugar,starch and protein contents were investigated.Results The moisture content was increased first and then dropped to 73.37% at maturity.The fresh and dry weight,starch and protein contents of P.notoginseng′s fruits were increased with the fruit development.The soluble sugar content was raised first,then decreased,and increased slightly at the lateral stage of fruit development.Conclusion The P.notoginseng′s fruits are mature at 80 d after peak anthesis;the decrease of moisture content is companied with the gradual increasing of fruit fresh and dry weight during the fruit development.The storage and utilization of nutrients in P.notoginseng′s fruits are closely related with the fruit development.

The impact of the pandemic, caused by SARS-CoV-2, on the management of malignancies has posed several challenges. Gestational trophoblastic diseases, being considered highly curative, are categorized as emergent cases which need immediate intervention with a level I priority for chemotherapy for its malignant spectrum. These guidelines have been drawn up to assist in decision-making and the implementation of such are dependent on the capabilities of each institution combined with their local experience.

Objective To develop and verify a plaque method for detection of infectious titer of tick-borne encephalitis virus(TBEV)strain(PHKT strain for short)adapted to primary hamster kidney(PHK)cells.Methods PHK cells were infected with TBEV,a primary mouse brain adaption strain,and passed consecutively for 12 passages.The titer of PHKT was detected by plaque method(Monolayer BHK-21 cells were infected with PHKT of various passages at different dilution ratios,and the plaque number was calculated by neutral red staining)and challenge titration in mouse brain(Mice were challenged with PHKT of various passages at different dilution ratios through brain cavity,0.03 mL for each,observed continuously for 14 days,and calculated for the median lethal dose(LD50)by Reed-Muench method)respectively,and the correlation between the results of two methods was analyzed.The developed plaque method for the detection of TBEV titer was verified for specificity,repeatability and intermediate precision.Results The plaque titer of PHKT virus was up to8.9 lgPFU/mL;The correlation between the results of plaque method and mouse brain challenge titration method was good(r = 0.92);The specificity of plaque method for detecting infectious titer of PHKT virus was good,and the coefficients of variation(CVs)of repeatability and intermediate precision were both less than 5%.Conclusion A plaque method for detecting infectious titer of PHKT virus was developed,which may be used as an alternative method for challenge titration in mouse brain.

Thermochemotherapy by drug-loaded magnetic micro/nano-particles is attracting increasing attention because it combines the advantages of chemotherapy and high targeting and selectivity of hyperthermia,especially intra-cellular hyperthermia.Magnetic micro/nano-particles,usually consisting of biodegradable pely-mers matrics co-incorporated with ferromagnetic particles and anti-cancer drugs,will generate heat when exposed to an externally applied alternating magnetic fields due to electromagnetic induction by ferro-particles,in the meanwhile,sensitivity of anti-cancer drug will be greatly enhanced by higher temperature.Tumors will greatly suppressed by the synergetic effect of chemotherapy and targeted hyperthermia.

The internet addiction disorder is an important problem under the internet circumstance.Improving self-regulated ability is a good method to avoid the problem.The article uses the selfregulated circle theory to gain the self-regulating strategy in three phases:forethought,performance or volitional control,self-reflection.These strategies include making goal,planning strategy,self-observation and self-record,attribution.

At present,research of genes and signal transduction pathway for etiology and pathogenesy of diseases is a hot topic.STAT3 signal transduction plays an important role in regulating cell proliferation,differentiation,survival and apoptosis.As a point of convergence for numerous oneogenie signaling pathways,STAT3 is constitutively activated in diverse human cancer cells.Current study suggest that activation of STAT3 signal transduction is closely related to the currence,development and malignant biological behaviors of tumor.STAT3 has been identified as a promising target for cancer treatment.
