The plant AT-rich sequence and zinc-binding protein (PLATZ) family is composed of plant-specific zinc finger-like transcription factors, which play important roles in plant growth, development, and stress tolerance. In this study, to gain a better understanding of the PLATZ gene in C. sinensis and elucidate its response under drought and high temperature conditions, the PLATZ gene family of the C. sinensis cultivar 'Tieguanyin' was systematically identified, and a total of 12 CsPLATZ family members were identified. Expasy online and other bioinformatics tools were used to analyze the members of the PLATZ gene family in terms of protein physicochemical properties, phylogenetic relationships, cis-acting elements, gene structures, and intra- and inter-species collinearity. The results of phylogenetic analysis classified the CsPLATZ family members into 2 subfamilies. The conserved domains and gene structures of PLATZ family members within the same subfamily had a high degree of consistency, whereas a certain degree of diversity was observed among the subfamilies. Twelve PLATZ genes were unevenly distributed across 7 chromosomes of C. sinensis and the promoter regions of these genes had multiple cis-acting elements related to hormone and stress responses. The collinearity analysis showed that there were 4 pairs of duplication events in the CsPLATZ gene family, all of which were segmental duplications. Based on this gene family, C. sinensis had a closer evolutionary relationship with A. thaliana than with O. sativa. The transcriptome analysis showed that the expression levels of CsPLATZ family members varied in different tissue samples of C. sinensis. 6 genes (CsPLATZ-1, CsPLATZ-2, CsPLATZ-3, CsPLATZ-4, CsPLATZ-6, and CsPLATZ-8) with high expression in shoots, young leaves, and roots were selected for high temperature and drought stress treatments, and their expression was quantified by qRT-PCR. The results indicated that the six genes might play important roles in the response to drought stress. In addition, CsPLATZ-2 and CsPLATZ-8 might have important functions in the response to high temperature stress. The results of this study will contribute to a better understanding of the biological functions of PLATZ genes and their possible roles in the growth, development, and stress responses of C. sinensis.

This article systematically studied the moxibustion methods embedded in the 15 medical books of the Mawangdui medical literature. Starting from the origin of the medical moxibustion culture in Mawangdui, this paper comprehensively analyzed the records of moxibustion. By analyzing the Classic of Moxibustion to Eleven Foot-arm Channels (《足臂十一脉灸经》) and Classic of Moxibustion to Eleven Yin-yang Channels (《阴阳十一脉灸经》) as well as Formulas for Fifty-two Diseases (《五十二病方》), which have relatively rich records of moxibustion, it is found that moxibustion involves more than 170 diseases and syndromes, covering 12 categories such as limb diseases related to meridians and collaterals, lung system diseases, and heart and brain diseases. In summary, the distinctive characte-ristics of moxibustion in Mawangdui medical books include primitive simplicity, combination of witch culture and medical practices, philosophical deduction, centripetal circulation, diverse moxibustion materials, extensive cove-rage of diseases and syndromes, taboos in moxibustion, and the integration of prevention and treatment. The ideas and applications of moxibustion mainly manifest in preventing diseases before they occur and preventing changes in existing diseases, distinguishing and treating each disease based on different causes, and combining treatment based on meridians, collaterals and comprehensive diseases.

The secondary structure is a fundamental feature of both non-coding RNAs (ncRNAs) and messenger RNAs (mRNAs). However, our understanding of the secondary structures of mRNAs, especially those of the coding regions, remains elusive, likely due to translation and the lack of RNA-binding proteins that sustain the consensus structure like those binding to ncRNAs. Indeed, mRNAs have recently been found to adopt diverse alternative structures, but the overall functional significance remains untested. We hereby approach this problem by estimating the folding specificity, i.e., the probability that a fragment of an mRNA folds back to the same partner once refolded. We show that the folding specificity of mRNAs is lower than that of ncRNAs and exhibits moderate evolutionary conservation. Notably, we find that specific rather than alternative folding is likely evolutionarily adaptive since specific folding is frequently associated with func-tionally important genes or sites within a gene. Additional analysis in combination with ribosome density suggests the ability to modulate ribosome movement as one potential functional advantage provided by specific folding. Our findings reveal a novel facet of the RNA structurome with important functional and evolutionary implications and indicate a potential method for distinguishing the mRNA secondary structures maintained by natural selection from molecular noise.

Objective: To investigate the effects of XIAOJI Decoction combined with FOLFOX chemotherapy on serum cytokine expression profile in patients with advanced colorectal carcinoma by liquid chip technology. Methods: Fourteen patients with advanced colorectal carcinoma, who met the inclusion criteria and were treated in the Department of Oncology, Higher Education Mega Center Hospital of Guangdong Provincial Hospital of Traditional Chinese Medicine during January 1, 2018 and December 31, 2018 were retrospectively analyzed in this study. The patients were divided into chemotherapy group (n=7, treated with 5-Fluorouracil + Calcium Folic Acid+Oxaliplatin (FOLFOX)) and combined treatment group (n=7, treated with XIAOJI Decoction + FOLFOX) according to therapeutic scheme. The curative efficacy was evaluated after 6 treatment courses. The expression profile of cytokines in blood serum of patients was examined by liquid chip technology after every 2 courses. Results: Fourteen patients received a total of 84 cycles of therapy. Survival analyses showed that the progress-free survival time (PFS) and overall survival time (OS) of two groups couldn't be compared due to insufficient samples, although the combined treatment group had longer PFS (10 months vs 6 months) and OS (17 months vs 12 months) than the chemotherapy group.As to adverse reactions, the rates of leucopenia, diarrhea, nausea, peripheral neuritis and alopecia in two groups were comparable, while the severity in combined treatment group were lighter than that in chemotherapy group. In comparison with the combined treatment group, concentrations of serum BDNF and IL-2 were statistically higher in the chemotherapy group (P<0.05). By comparing the cytokine concentrations at different collection time points before and after the treatment, it showed that the concentration of serum IL-2 in chemotherapy group was higher than that in combined treatment group after 2 courses of treatment (P<0.05). In total, there were 19 cytokines showed a tendency to be higher in combined treatment group than chemotherapy group during different treatment periods. Conclusion: Combined treatment of XIAOJI Decoction with FOLFOX for advanced colorectal carcinoma is a treatment option worth exploring, and liquid chip analysis showed that the mechanism may be related to the reduction of serum LI-2 and BDNF levels in patients.
