Objective:To explore the clinical short-term efficacy of venetoclax (Ven) combined with azacitidine (AZA) in treatment of newly treated and relapsed/refractory patients with acute myeloid leukemia (AML).Methods:The data of 18 newly treated and relapsed/refractory patients with AML who received Ven+AZA treatment in Suzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing University of Chinese Medicine from April 2020 to June 2022 were retrospectively analyzed. The complete remission or complete remission with incomplete recovery of blood cell count (CR/CRi) and objective remission rate (ORR) [calculated as CR/CRi+partial remission (PR)] were analyzed in newly treated and relapsed/refractory patients or patients with different gene mutations. The patients were followed up until June 30, 2022, and the overall survival (OS) of relapsed/refractory patients was analyzed. The occurrence of adverse reactions was summarized.Results:The median age of the 18 patients was 58 years old (23-81 years old), 8 were males and 10 were females; 6 were newly treated and 12 were relapsed/refractory; the median follow-up time was 3 months (1-15 months). In 6 newly treated patients, after the first cycle of Ven+AZA, 5 cases achieved CR/CRi, and the ORR was 83.3% (5/6). In 12 relapsed/refractory patients, after the first cycle of Ven+AZA, 5 cases achieved CR/CRi, 3 achieved PR, and the ORR was 66.7% (8/12). Among the 18 patients, 7 cases had FLT3-ITD/TKD mutation, after the first cycle of Ven+AZA, 1 case achieved CR/CRi, 1 case achieved PR, and the ORR was 28.6% (2/7); 3 cases had NPM1 mutation combined with FLT3-ITD/TKD mutation, 1 case achieved CR/CRi, and the ORR was 33.3% (1/3); 4 cases had IDH1/2 mutation, and 3 cases of them combined with FLT3-ITD/TKD mutation, all of which were non-remission, and the other 1 relapsed/refractory patient combined with K/NRAS mutation achieved CR/CRi; among the 4 cases with K/NRAS mutation, 2 cases combined with FLT3-ITD/TKD mutation, including 1 case of NR and 1 case of PR, and the other 2 cases achieved CR/CRi, the ORR was 75.0% (3/4). Of the 12 relapsed/refractory patients, 6 died by the end of follow-up, with a median OS time of 2.6 months (1- 8 months), including 4 cases of disease progression and 2 cases of disease relapse; the 6 surviving patients had stable disease. All the 18 patients had ≥grade 3 hematologic adverse reactions, and non-hematologic adverse reactions included lung infection, nausea, vomiting and diarrhea.Conclusions:Ven+AZA treatment for newly treated and relapsed/refractory AML patients results in a high response rate with tolerable adverse reactions, but it is not effective in AML patients with FLT3-ITD/TKD mutation.

Association between cognitive impairment and main metals among oldest old aged 80 years and over in China / 中华预防医学杂志

Objective: To identify the main metals involved in cognitive impairment in the Chinese oldest old, and explore the association between these metal exposures and cognitive impairment. Methods: A cross-sectional study was conducted on 1 568 participants aged 80 years and older from Healthy Aging and Biomarkers Cohort Study (2017 to 2018). Fasting venous blood was collected to measure the levels of nine metals (selenium, lead, cadmium, arsenic, antimony, chromium, manganese, mercury, and nickel). The cognitive function of these participants was evaluated by using the Chinese version of the Mini-Mental State Examination (CMMSE). The random forest (RF) was applied to independently identify the main metals that affected cognitive impairment. The multivariate logistic regression model and restricted cubic splines (RCS) model were used to further verify the association of the main metals with cognitive impairment. Results: The age of 1 568 study subjects was (91.8±7.6) years old, including 912 females (58.2%) and 465 individuals (29.7%) with cognitive function impairment. Based on the RF model (the out-of-bag error rate was 22.9%), the importance ranking of variables was conducted and the feature screening of five times ten-fold cross-validation was carried out. It was found that selenium was the metal that affected cognitive function impairment, and the other eight metals were not included in the model. After adjusting for covariates, the multivariate logistic regression model showed that with every increase of 10 μg/L of blood selenium levels, the risk of cognitive impairment decreased (OR=0.921, 95%CI: 0.889-0.954). Compared with the lowest quartile(Q1) of blood selenium, the ORs (95%CI) of Q3 and Q4 blood selenium were 0.452 (0.304-0.669) and 0.419 (0.281-0.622) respectively. The RCS showed a linear dose-response relationship between blood selenium and cognitive impairment (Pnonlinear>0.05). Conclusion: Blood selenium is negatively associated with cognitive impairment in the Chinese oldest old.

Association of blood lead and blood selenium with serum high-sensitivity C-reactive protein among Chinese adults aged 19 to 79 years / 中华流行病学杂志

Objective: To investigate the association of blood lead and blood selenium with serum high-sensitivity C-reactive protein (hs-CRP) among Chinese adults aged 19 to 79 years. Methods: The participants were enrolled from the first wave of China National Human Biomonitoring (CNHBM) conducted from 2017 to 2018. 10 153 participants aged 19 to 79 years were included in this study. Fasting blood samples were obtained from participants. Lead and selenium in whole blood and hs-CRP in serum were measured. Individuals with hs-CRP levels above 3.0 mg/L were defined as elevated hs-CRP. Generalized linear mixed models and restricted cubic spline models were used to analyze the association of blood lead and blood selenium with elevated hs-CRP. Logistic regression models were used to analyze the multiplicative scale and additive scale interaction between blood lead and blood selenium on elevated hs-CRP. Results: The age of participants was (48.91±15.38) years, of which 5 054 (61.47%) were male. 1 181 (11.29%) participants were defined as elevated hs-CRP. After multivariable adjustment, results from generalized linear models showed that compared with participants with the lowest quartile of blood lead, the OR (95%CI) of elevated hs-CRP for participants with the second, third, and highest quartiles were 1.14 (0.94-1.37), 1.25 (1.04-1.52) and 1.38 (1.13-1.68), respectively. When compared with participants with the lowest quartile of blood selenium, the OR (95%CI) of elevated hs-CRP for participants with the second, third and highest quartiles were 0.86 (0.72-1.04), 0.91 (0.76-1.11), and 0.75 (0.61-0.92), respectively. Results from the interaction analysis showed no significant interaction between lead and selenium on elevated hs-CRP. Conclusion: Blood concentration of lead was positively associated with elevated serum hs-CRP, and blood concentration of selenium was inversely related to elevated hs-CRP, while blood lead and selenium did not present interaction on elevated hs-CRP.

Community structure of bacterioplankton and its relationship with environmental factors in the upper reaches of the Heihe River in Qinghai Plateau.

Planktonic microorganisms play a key role in the biogeochemical processes of the aquatic system, and they may be affected by many factors. High-throughput sequencing technology was used in this study to investigate and study the bacterioplankton community of water bodies in the upper reaches of the Heihe River Basin in Qinghai Plateau. Results showed that Proteobacteria, Firmicutes, Bacteroidetes and Actinobacteria are the predominant phyla in this river section, while the main genera are Thiomonas, Acidibacillus, Acidocella, Rhodanobacter, Acidithiobacter and Gallionella, which are autochthonous in the acid-mine drainage. Additionally, total nitrogen, total phosphorus, permanganate index and pH are significantly correlated with the bacterioplankton abundance and are the main limiting factors for the spatial distribution of the bacterioplankton. PICRUSt inferred that the mainstream microbial assemblages had a higher abundance of KOs belong to metabolism of terpenoids and polyketides, while the tributary had higher abundance of KOs belong to the immune system. The relationship between bacterioplankton community composition and environmental factors in the Heihe River basin was discussed for the first time in this study, which provides a theoretical basis for the healthy, orderly development of the water environment in the Heihe River Basin.

Fructus Aurantii induced antidepressant effect via its monoaminergic mechanism and prokinetic action in rat.

Depression could hardly get a satisfactory effect from the currently available antidepressants. To get a more effective treatment, antidepressant effect and monoaminergic mechanism of Fructus Aurantii (FRA) in the rat forced swimming test (FST) and open field test (OFT), and its prokinetics were examined. FST and OFT were respectively used to evaluate the antidepressant effect and locomotor activity of FRA. We observed the effects of monoamine receptor antagonists on FRA-induced antidepressant effect in rat. The effects of FRA on intestinal transit, gastric emptying and in vitro jejunum contractile activity were assessed. FRA decreased significantly the immobility time (32.6±8.5, 30.3±5.2 vs 56.4±9.4, all p<0.01) in FST, dose-dependent increased the locomotor activity (102±17.5, 120±18.5 vs 89±9.8, p<0.05 or 0.01), significantly accelerated gastric emptying (GE: 48.1±6.3, 39.5±5.7 vs 19.5±3.8, p<0.01) and intestinal transit (IT: 67.3±9.1, 64.2±6.3 vs 49.1±8.2, p<0.01) of the semi-liquid meal, compared with vehicle. And FRA (1 µM, 10 µM) significantly increased the mean amplitude (0.24±0.021 and 0.281±0.015) of contraction in jejunum of rat compared with vehicle (0.149±0.011) in vitro. FRA (10 µM) could induce a largest amplitude (0.281±0.015) of contraction in jejunum. The anti-immobility effect of FRA in FST was prevented by pre-treatment of rat with p-chlorophenylalanine methyl ester, WAY100635, ketanserin, haloperidol, SCH233390, sulpiride, yohimbine, but not prazosin. FRA could simultaneously induce prokinetics and antidepressant effect, deserves further to investigate.

Effects of electroacupuncture on the apoptosis of brain tissue cells and the expression of Caspase-3 in the rats with cerebral-cardiac syndrome / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the effects of electroacupuncture (EA) on the apoptosis of brain tissue cells and the expression of Caspase-3 in the rats with cerebral-cardiac syndrome (CCS).</p><p><b>METHODS</b>A total of 70 healthy SD rats were selected. Ten was randomly recruited as the sham-operation group, and the rest were used for CCS model preparation. Thirty successfully modeled rats were divided into the model group, the EA group, and the non-EA group, 10 in each group. The model was prepared using injecting collagenase + heparin into the caudate nucleus. Equal volume of 0.9% sodium chloride injection was injected to rats' caudate nucleus in the sham-operation group. EA was started on the 1st day of modeling. Shuigou (GV26), Fengfu (GV16), Neiguan (PC6), and Xinshu (BL15) were needled in the EA group. Four points in the hips were needled in the non-EA group. The EA needling lasted for 20 min each time, once daily, for 3 successive times. No EA was administered to the sham-operation group or the model group. The apoptosis of brain tissue around the hematoma and the expression of Caspase-3 were detected using TUNEL and immunochemical assay.</p><p><b>RESULTS</b>TUNEL cells could be occasionally seen with fewer Caspase-3 expression in the sham-operation group. More TUNEL positive cells appeared in the tissue around the hematoma of the model group with a large amount of Caspase-3 expression. The TUNEL positive cells and Caspase-3 expression were obviously less in the EA group than in the model group and the non-EA group (P < 0.01).</p><p><b>CONCLUSIONS</b>EA could inhibit the apoptosis of brain tissue cells in CCS rats. Its mechanisms might be associated with down-regulating the Caspase-3 expression of the brain tissue around the hematoma.</p>

<p><b>OBJECTIVE</b>To study four kinds of germplasm resources of Codonopsis pilosula and provide the basal mating systems data for the breeding and cultivation of C. pilosula.</p><p><b>METHOD</b>0.5% TTC (2,3,5-triphenyl tetrazolium chloride) solution was used for the pollen viability test and benzidineand-H2O2 [1% benzidine in 60% ethanol,hydrogen peroxide (3%), and water, 4:11:22] was used for estimation of the stigma receptivity. The mating systems were tested by out crossing index (OC1), pollen-ovule ratio (P/O) and pollination by bagged and emasculated in the field.</p><p><b>RESULT</b>The pollen viability of C. pilosula reached highly about 80% when the pollen staying in the anther, 2-3 days before the petals opening. The anther began scattering pollen before the day of the petals opening, the pollen viability was the highest about 95%, the pollen stick thickly aroud the stigma and quickliy lost in the next day. The stigma life-span was about 4-5 days, the optimal time for pollination was the first day of the petals opening, when the stigma was highly sticky and yellow. The value of out crossing index (OC1) was 4, pollen-ovule ratio was between 104.84-185.75. The natural fructification rate of cross-pollination by emasculated-treatment was 25.6% 42.4%. The fructification rate and compatible index of self-pollination by bagged- treatment were about 3.3%-6.7% and 3.0-21.8.</p><p><b>CONCLUSION</b>The mating system of C. pilosula is mixed with self-pollination and cross-pollination, prone to cross-pollination. The compatibility of self-pollination is high. The difference of maturing period of pistil and stamen and the lack of polen amount cause low fructification rate of self-pollination.</p>

Methods A total of 25 liver masses in 20 patients with an indeterminate diagnosis based on 18F-FDG PET/CT were enrolled. Regional 11C-choline PET/CT scan was performed in all of the patients. Lesions with intense 11C-choline uptake were considered as positive. The semiquantitative maximum standardized uptake value(SUVmax) was measured and the tumor-to-liver (T/L) radioactivity ratio was calculated. The Mann-Whitney test,Kruskal-Wallis test and crosstabs x2-test were performed by using SPSS version 11.5. Results Of the 25 lesions,21 were proven to be hepatocellular carcinomas (HCC),3 hemangiomas,and 1 parasitic granuloma. The sensitivity of 11C-choline PET/CT for the detection of HCC was 66.7% (14/21). 11C-choline PET/CT had a higher sensitivity for well differentiated HCC than moderately and poorly differentiated HCC on a patient basis (8/9 vs 2/5,respectively). There were significant differences of 11C-choline T/L ratios between the HCC positive group,HCC negative group and benign lesion group ( 1.70 ± 0.35,0.86 ± 0.15,and 0.36 ± 0.18,x2 = 19.00,P ＜0.01 ). The lesion size and alphafetoprotein (AFP) level between the HCC positive and negative groups had no significant difference respectively ( Mann Whitney U = 39.00,P ＞0.05,and U=16.00,P＞0.05,respectively). Conclusions 11C-choline is complementary to 18F-FDG PET/CT for the detection of HCC,especially for well differentiated HCC.
