OBJECTIVE: To detect and analyze the expression and clinical significance of long non-coding RNA tyrosine kinase non-catalytic region adaptor protein 1-antisense RNA1 (NCK1-AS1) in patients with acute myeloid leukemia (AML). METHODS: 89 AML patients and 23 healthy controls were included from the People's Hospital Affiliated to Jiangsu University. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression levels of NCK1-AS1 and NCK1 in bone marrow samples. The relationship between the expression of NCK1-AS1 and the clinical characteristics of patients were analyzed, as well as the correlation between NCK1-AS1 and NCK1. RESULTS: The expression level of NCK1-AS1 in all AML, non-M3 AML and cytogenetically normal AML (CN-AML) patients was significantly higher than that in the control group (P < 0.01, P < 0.05, P < 0.01, respectively). In non-M3 AML, patients with high NCK1-AS1 expression had a significantly lower hemoglobin level than those with low NCK1-AS1 expression (P =0.036), furthermore, NCK1-AS1 ^high patients had shorter overall survival than NCK1-AS1^low patients (P =0.0378). Multivariate analysis showed that NCK1-AS1 expression was an independent adverse factor in patients with non-M3 AML ( HR =2.392, 95% CI :1.089-5.255, P =0.030). In addition, NCK1 expression was also significantly upregulated in all AML, non-M3 AML and CN-AML patients compared with controls (P < 0.01, P < 0.01, P < 0.001, respectively). There was a certain correlation between NCK1-AS1 and NCK1 expression (r =0.37, P =0.0058). CONCLUSION High expression of NCK1-AS1 in AML indicates poor prognosis of AML patients.

Glutamine provides carbon and nitrogen to support the proliferation of cancer cells. However, the precise reason why cancer cells are particularly dependent on glutamine remains unclear. In this study, we report that glutamine modulates the tumor suppressor F-box and WD repeat domain-containing 7 (FBW7) to promote cancer cell proliferation and survival. Specifically, lysine 604 (K604) in the sixth of the 7 substrate-recruiting WD repeats of FBW7 undergoes glutaminylation (Gln-K604) by glutaminyl tRNA synthetase. Gln-K604 inhibits SCFFBW7-mediated degradation of c-Myc and Mcl-1, enhances glutamine utilization, and stimulates nucleotide and DNA biosynthesis through the activation of c-Myc. Additionally, Gln-K604 promotes resistance to apoptosis by activating Mcl-1. In contrast, SIRT1 deglutaminylates Gln-K604, thereby reversing its effects. Cancer cells lacking Gln-K604 exhibit overexpression of c-Myc and Mcl-1 and display resistance to chemotherapy-induced apoptosis. Silencing both c-MYC and MCL-1 in these cells sensitizes them to chemotherapy. These findings indicate that the glutamine-mediated signal via Gln-K604 is a key driver of cancer progression and suggest potential strategies for targeted cancer therapies based on varying Gln-K604 status.

ObjectiveTo explore the correlations between the medicinal parts， habitats， tissue， components， and medicinal properties （natures， tastes， and effects） of 100 aquatic Chinese medicinal plants， thus providing evidence for the relationship between image and analogy and laying a theoretical foundation for the clinical use and development of aquatic Chinese medicinal plant resources. MethodThe Aquatic Plants of China， Flora of China， and related literature were searched， and a total of 100 aquatic Chinese medicinal plants included in the Chinese Pharmacopoeia （2020 edition）， Chinese Materia Medica， National Compilation of Chinese Herbal Medicines， Dictionary of Chinese Materia Medica， and local standards were screened out. The medicine-taxonomic status-life habit associations and nature-component-traditional Chinese medicine classification-pharmacological effect associations were analyzed respectively. ResultThe aquatic Chinese medicinal plants mostly had a cold nature， bitter， pungent， and sweet tastes， and tropism to the liver meridian. The whole plant or aerial part was mainly used for medicinal purposes， and these plants generally had well developed aerenchyma. These plants mainly contained flavonoids， alkaloids， and volatile oils and had the effects of clearing heat， detoxifying， and promoting urination. ConclusionThere are correlations between the medicinal parts， habitats， tissue， components， medicinal properties， and effects of aquatic Chinese medicinal plants， which provide reference for the development and utilization of aquatic Chinese medicinal plant resources.

ObjectiveTo make statistics on the biological characteristics， medicinal parts， chemical components， and other aspects of thorny medicinal plants and systematically analyze the correlations between their natures， tastes， and meridian tropism， so as to provide a theoretical basis for the clinical application and resource development of these plants. MethodThe Chinese Pharmacopoeia （2020 edition） and the processing standards of various provinces and cities and other related documents were reviewed， on the basis of which 46 species of thorny medicinal plants were selected. The natures， tastes， meridian tropism， medicinal parts， chemical components， pharmacological activities， and geographical distribution of these plants were summarized and analyzed in Excel 2013 and SPSS Statistics 26.0. ResultThe 46 species of thorny medicinal plants belonged to 25 families， 1 class， 1 phylum of 1 kingdom. In terms of the location of thorns， the frequency of these medicinal plants followed the trend of leaf thorns>peel thorns>branch thorns>fruit thorns. In terms of the nature， taste， and meridian tropism， the frequency of these plants was in the orders of warm>plain>cold>cool>hot， bitter>sweet>pungent>sour>salty， and liver>lung>spleen=large intestine>heart>kidney， respectively. In terms of the medicinal parts， the frequency followed the trend of roots and rhizomes>fruits>whole plants>flowers>leaves. The thorny medicinal plants were mainly distributed in north and southwest China. The thorny medicinal plants mainly contained flavonoids， alkaloids， and saponins and had the effects of clearing heat and detoxifying， resolving stasis and eliminating carbuncle， moving Qi and relieving pain， and alleviating edema and expelling pus. Moreover， 24 of them had anti-tumor activity. ConclusionMost of the thorny medicinal plants belong to Compositae， Leguminosae， and Rosaceae， have leaf thorns， a warm nature， a bitter taste， tropism to the liver meridian， and roots as the medicinal part. These plants are mainly distributed in north China， with the effects of clearing heat and detoxifying， resolving stasis and eliminating carbuncle. In summary， the thorn location， distribution， and medicinal parts of thorny medicinal plants are correlated with the natures， tastes， and meridian tropism. The findings provide clues for the development and utilization of these plants.

ObjectiveThe correlation of Pueraria lobata producing areas， climate factors， total flavonoids of P. lobata， polysaccharide content of P. lobata， and antioxidant activity of P.lobata for medicinal application was analyzed， and the relationship between climate factors and the formation of P. lobata quality was evaluated. MethodThe scavenging rates of 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl（DPPH） and 2, 2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)（ABTS） radicals by total flavonoids and polysaccharides of P. lobata were detected， and the correlation between the contents of each component and the information of producing areas and climate factors was analyzed. ResultThe ABTS⁺ scavenging rate by total flavonoids of P.lobata was negatively correlated with altitude （P<0.05） and positively correlated with annual sunshine hours （P<0.05）. The altitude was positively correlated with the total flavonoid content， while the annual sunshine hours were negatively correlated with the total flavonoid content. There was a negative correlation between total flavonoid content and ABTS⁺ scavenging rate by total flavonoids. In other words， lower altitude and longer annual sunshine hours indicated lower total flavonoid content and higher ABTS⁺ scavenging rate by total flavonoids. The ABTS⁺ scavenging rate by polysaccharides of P. lobata was negatively correlated with the frost-free period （P<0.05） and the mean temperature in July （P<0.01）. There was a positive correlation between the polysaccharide content of P. lobata and the frost-free period. The mean temperature in July was positively correlated with the polysaccharide content of P. lobata （P<0.05）. The polysaccharide content of P. lobata was negatively correlated with the ABTS⁺ scavenging rate by polysaccharides of P. lobata. In other words， a shorter frost-free period in the producing area and lower mean temperature in July indicated lower polysaccharide content of P. lobata and higher ABTS⁺ scavenging rate by polysaccharides of P. lobata. The mean temperature in July was significantly correlated with the contents of total flavonoids and polysaccharides in P. lobata samples （P<0.05）. The lower mean temperature in July was often accompanied by lower total flavonoid content of P. lobata， lower polysaccharide content of Pueraria lobata， and stronger antioxidant activity of P. lobata samples. ConclusionThe ability of P. lobata to remove ABTS⁺ is stronger than that of DPPH⁺. There is a significant correlation between climate factors， content， and antioxidant capacity in each producing area. Further research on the internal law of the formation of medicinal active components of P. lobata induced by core climate factors will provide a scientific basis for revealing the formation mechanism of genuine P. lobata and the subsequent control of P. lobata quality according to the environment of producing areas.

The assessment results from 2006 to 2008 were tested for outliers using Grubbs method, homogeneity of variance using Cochran method, excluding the assessment data of unqualified laboratories, calculating the total mean and total standard deviation, Z-score method was used to test the assessment of laboratories, and statistical analysis and judgment were done when the result of │Z│ < 3. The assessment results from 2009 - 2023 were obtained from all laboratories. In 2010, two tests were conducted in the first and second half of the year, and the Z-ratio scores of each laboratory were calculated using robust statistics. When │Z│≤2, the assessment was qualified; when 2 < │Z│ < 3, the assessment was basically qualified; when│Z│≥3, the assessment was unqualified, and the consensus value came from all participating laboratories in the assessment.Results:From the beginning of quality control operation in 2006 to 2023, the number of laboratories participated in external quality control assessments had significantly increased. The number of laboratories participated in water fluoride assessment increased from 30 in 2006 to 1 277 in 2023, and the number of laboratories participated in urine fluoride assessment increased from 29 to 497. The number of laboratories participated in the brick tea fluorine assessment had increased from 43 in 2014 to 193 in 2023. The assessment results showed that when │Z│ < 3, the total qualified rate of fluoride external quality control in fluoride testing laboratories of national endemic disease control institutions was 95.2%, with the lowest being 87.1% (27/31) in 2008 and the highest being 100.0% (394/394) in 2014. When │Z│≤2, the total feedback pass rate was 88.4%, with the lowest being 79.3% (288/363) in the first half of 2010 and the highest being 99.5% (392/394) in 2014. The assessment results showed that when │Z│ < 3, the total pass rate of urine fluoride external quality control in fluoride testing laboratories of national endemic disease control institutions was 98.0%, with the lowest being 86.2% (25/29) in 2006 and 2007, respectively, and the highest being 100.0% (68/68) in 2014. When │Z│≤2, the total qualification rate was 93.7%, with the lowest being 86.5% (64/74) in the second half of 2010 and the highest being 100.0% (68/68) in 2014. The assessment results showed that when│Z│ < 3, the total pass rate of extra-fluoride quality control of brick tea in fluoride testing laboratories of national endemic disease control institutions was 95.4%, with the lowest being 85.0% (164/193) in 2023, and the highest being 100.0% (43/43, 51/51, 79/79) in 2014, 2015 and 2016, respectively. When │Z│≤2, the total pass rate was 89.2%, with the lowest being 72.7% (32/44) in 2017 and the highest being 100.0% (43/43) in 2014. From 2009 to 2023, there were a total of 21 provincial-level laboratories that passed the water fluoride detection assessment, including 3 provinces where all prefecture level and county-level laboratories were qualified. The assessment results of urinary fluorine showed that there were 11 qualified provincial-level laboratories and 1 prefecture-level laboratory. From 2014 to 2023, the assessment results of brick-tea fluorine showed that there were 5 provincial-level laboratories that passed the tea fluorine testing assessment and no prefecture-level laboratory.Conclusions:Conclusion: From 2006 to 2023, the number of fluoride testing laboratories participating in external quality control assessment has increased year by year, and most provincial, municipal and county-level laboratories have good fluoride testing capabilities, which can meet the testing needs of endemic disease prevention and monitoring. For some laboratories with problems, targeted rectification should be carried out to improve the quality of detection, in order to provide better technical support for the monitoring of endemic fluorosis areas.

OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).
