Abstract
RUNX1 is one of the recurrent mutated genes in newly diagnosed acute myeloid leukemia (AML). Although historically recognized as a provisional distinct entity, the AML subtype with RUNX1 mutations (AML-RUNX1mut) was eliminated from the 2022 WHO classification system. To gain more insight into the characteristics of AML-RUNX1mut, we retrospectively analyzed 1065 newly diagnosed adult AML patients from the First Affiliated Hospital of Soochow University between January 2017 and December 2021. RUNX1 mutations were identified in 112 patients (10.5%). The presence of RUNX1 mutation (RUNX1mut) conferred a lower composite complete remission (CRc) rate (40.2% vs. 58.4%, P<0.001), but no significant difference was observed in the 5-year overall survival (OS) rate (50.2% vs. 53.9%; HR=1.293; P=0.115) and event-free survival (EFS) rate (51.5% vs. 49.4%; HR=1.487, P=0.089), even within the same risk stratification. Multivariate analysis showed that RUNX1mut was not an independent prognostic factor for OS (HR=1.352, P=0.068) or EFS (HR=1.129, P=0.513). When patients were stratified according to induction regimen, RUNX1mut was an unfavorable factor for CRc both on univariate and multivariate analysis in patients receiving conventional chemotherapy, and higher risk stratification predicted worse OS. In those who received venetoclax plus hypomethylating agents, RUNX1mut was not predictive of CRc and comparable OS and EFS were seen between intermediate-risk and adverse-risk groups. The results of this study revealed that the impact of RUNX1mut is limited. Its prognostic value depended more on treatment and co-occurrent abnormalities. VEN-HMA may abrogate the prognostic impact of RUNX1, which merits a larger prospective cohort to illustrate.

Abstract
Changes in global climate and precipitation patterns have exacerbated the existing uneven distribution of water, causing many plants to face the alternate situation of drought and water flooding. We studied the growth and physiological response of the wetland plant Artemisia selengensis to drought and rehydration. In this study, Artemisia selengensis seedlings were subjected to 32.89% (SD), 47.36 % (MD), 60.97% (MID), and 87.18 % (CK) field water holding capacity for 70 days, followed by 14 days of rehydration. The results showed that drought inhibited the increase of plant height, basal diameter, and biomass accumulation under SD and MD, but the root shoot ratio (R/S) increased. Drought stress also decreased the content of total chlorophyll (Chl), chlorophyll a (Chl-a), chlorophyll b (Chl-b), and carotenoid (Car). Soluble sugar (SS) and proline (Pro) were accumulated rapidly under drought, and the relative water content (RWC) of leaves was kept at a high level of 80%. After rehydration, the plant height, basal diameter, biomass, and R/S ratio could not be recovered under SD and MD, but these indicators were completely recovered under MID. The RWC, Chl, Chl-a, Chl-b, Car, and osmotic substances were partially or completely recovered. In conclusion, Artemisia selengensis not only can improve drought resistance by increasing the R/S ratio and osmotic substances but also adopt the compensatory mechanism during rehydration. It is predictable that A. selengensis may benefit from possible future aridification of wetlands and expand population distribution.

Abstract
Objective: To investigate the effect of the neoadjuvant chemotherapy course adjustment on the patients with esophageal cancer underwent delayed operation. Methods: The clinical data of patients with esophageal cancer treated in Cancer Hospital, Chinese Academy of Medical Sciences from 2019-2020, who underwent neoadjuvant chemotherapy strategy adjustment (multiple course chemotherapy group) or not (control group), were retrospectively studied. The clinical pathological characteristics and postoperative complication of these two group were compared and analyzed. Results: The cases who underwent the interval between chemotherapy and operation more than 4 weeks in multiple course chemotherapy group and control group were 17 and 6, with significant difference (P<0.05). The average operative blood loss of these two groups were 88.6 ml and 46.1 ml, the average postoperative hospital stays were 14.7 days and 10.0 days, with significant difference (P<0.05). The incidence rate of postoperative complication in the multiple course chemotherapy group was 40.9% (9/22), not significantly different from 31.8% (7/22) of control group (P>0.05). There were no death within postoperative 7 days and 30 days in both groups. Cases with apparent tumor regression [tumor regression grade (TRG) 1 to 3] in multiple course chemotherapy group were 14, with marginal tumor regression (TRG 4 to 5) were 8, while there were 7 and 15 in the control group, respectively, with significant difference (P<0.05). After multiple neoadjuvant chemotherapy, the imaging examination of patients indicated an almost total tumor degradation and the postoperative pathology showed no residual malignant tumor tissue was observed. Conclusions: Increased neoadjuvant chemotherapy course for patients with locally advanced esophageal cancer can obtain more obvious tumor degradation response. Neoadjuvant chemotherapy adjustment according to the operation schedule is recommended.

Abstract
Dental pulp has intrinsic capacity for self-repair. However, it is not clear whether dental pulp cells can be recruited endogenously for regenerating pulp tissues, including mineralizing into dentin. This work is based on a hypothesis that dental pulp stem/progenitor cells can be induced to migrate by chemotactic cytokines and act as endogenous cell sources for regeneration and mineralization. Dental stem cells (DSCs) were isolated from adult human tooth pulp and seeded on the surfaces of 3D collagen gel cylinders that were incubated in chemically defined media with stromal-derived factor-1α (SDF1), basic fibroblast growth factor (bFGF), or bone morphogenetic protein-7 (BMP7). Significantly more cells were recruited into collagen gel by SDF1 or bFGF than without cytokines in 7 days, whereas BMP7 had little effect on cell recruitment. BMP7, however, was highly effective, equally to dexamethasone, in orchestrating mineralization of cultured DSCs. Cell membrane receptors for SDF1, bFGF, and BMP7 were up-regulated in treated DSCs. Upon in vivo delivery, bFGF induced re-cellularization and re-vascularization in endodontically treated human teeth implanted into the dorsum of rats. Thus, endogenous dental pulp cells, including stem/progenitor cells, may be recruited and subsequently differentiated by chemotaxis of selective cytokines in the regeneration of dental pulp.

Abstract
OBJECTIVE To establish a hairy root culture system by double transformation for Trichosanthes kirilowii. METHOD 1. Crown galls were induced by direct infection of sterile seedlings of T. kirilonii with Agrobacterium tumefaciens C58, and then the hairy roots were obtained from the regenerated plants by infection with A. rhzogenes 15834; 2. Transformation of Ti and Ri plasmids was inspected by high-pressure-paper electrophoresis; 3. The protein contents in the tissues of T. kirilowii were inspected by spectrophotometer and SDS-PAGE. RESULT A hairy root culture system has been established successfully by double transformation with Ti and Ri plasmids in T. kirilowii. CONCLUSION Compared with the ordinary hairy roots, the double transformed hairy roots grow faster but retain similar protein contents.

Abstract
AIM To determine the dynamics of growth and total tanshinones accumulation in crown gall cultures of Salvia miltiorrhiza in MS and 67-V liquid media. METHODS Fresh, dry weight and total tanshinones yields in the cultures and in the medium were determined every 5 days in crown gall suspension cultures. RESULTS In MS medium, the logarithmic growth phase of crown gall cultures in S. miltiorrhiza was from the 5th to 30th days, and the stationary growth phase was from the 30th to 35th days. From the 25th to 30th days, physiological activity of crown gall cultures was higher and their growth was better. However, in 67-V medium, the logarithmic growth phase of crown gall cultures was from the 10th to 25th days, and the stationary growth phase was from the 25th to 35th days. Total tanshinones were largely accumulated in the cultures and in the medium after 25 days. The total tanshinones yield (60 mg.L-1) was reached at the 35th day. CONCLUSION Knowing the regularity of the growth and total tanshinones accumulation in crown gall cultures of S. miltiorrhiza will be helpful to take proper regulative measures in order to obtain the maximum total tanshinones yield.
