Relationship between Dining Place, Iodine Source, and Iodine Nutrition in School-Age Children: A Cross-Sectional Study in China / 生物医学与环境科学（英文）

OBJECTIVE@#This study assesses the impact of iodine-rich processed foods and dining places on the iodine nutritional status of children.@*METHODS@#School-aged children (SAC) in seven provinces in China were selected by school-based multi-stage sampling. Urinary iodine, salt iodine, and thyroid volume (TVOL) were determined. Questionnaires were used to investigate dining places and iodine-rich processed foods. The water iodine was from the 2017 national survey. Multi-factor regression analysis was used to find correlations between variables.@*RESULTS@#Children ate 78.7% of their meals at home, 15.1% at school canteens, and 6.1% at other places. The percentage of daily iodine intake from water, iodized salt, iodine-rich processed foods, and cooked food were 1.0%, 79.2%, 1.5%, and 18.4%, respectively. The salt iodine was correlated with the urinary iodine and TVOL, respectively (r = 0.999 and -0.997, P < 0.05). The iodine intake in processed foods was weakly correlated with the TVOL (r = 0.080, P < 0.01). Non-iodized salt used in processed foods or diets when eating out had less effect on children's iodine nutrition status.@*CONCLUSION@#Iodized salt remains the primary source of daily iodine intake of SAC, and processed food has less effect on iodine nutrition. Therefore, for children, iodized salt should be a compulsory supplement in their routine diet.

Depression status of elderly patients with metabolic syndrome in three provinces of China / 中华流行病学杂志

Objective: To understand the depression status and its influencing factors in elderly patients with MS in China and to explore the correlation between various components of elderly MS and depression. Methods: This study is based on the "Prevention and Intervention of Key Diseases in Elderly" project. We used a multi-stage stratified cluster random sampling method to complete 16 199 elderly aged 60 years and above in 16 counties (districts) in Liaoning, Henan, and Guangdong Provinces in 2019, excluding 1 001 missing variables. Finally, 15 198 valid samples were included for analysis. The respondents' MS disease was obtained through questionnaires and physical examinations, and the respondents' depression status within the past half month was assessed using the PHQ-9 Depression Screening Scale. The correlation between elderly MS and its components and depression and its influencing factors were analyzed by logistic regression. Results: A total of 15 198 elderly aged 60 years and above were included in this study, with the prevalence of MS at 10.84% and the detection rate of depressive symptoms in MS patients at 25.49%. The detection rates of depressive symptoms in patients with 0, 1, 2, 3, and 4 MS abnormal group scores were 14.56%, 15.17%, 18.01%, 25.21%, and 26.65%, respectively. The number of abnormal components of MS was positively correlated with the detection rate of depressive symptoms, and the difference between groups was statistically significant (P<0.05). The risk of depression symptoms in patients with MS, overweight/obesity, hypertension, diabetes, and dyslipidemia was 1.73 times (OR=1.73, 95%CI:1.51-1.97), 1.13 times (OR=1.13, 95%CI:1.03-1.24), 1.25 times (OR=1.25, 95%CI:1.14-1.38), 1.41 times (OR=1.41, 95%CI:1.24-1.60), 1.81 times (OR=1.81,95%CI:1.61-2.04), respectively, more than those without the disease. Multivariate logistic regression analysis showed that the detection rate of depressive symptoms in patients with sleep disorders was higher than that with normal sleep (OR=4.89, 95%CI: 3.79-6.32). The detection rate of depressive symptoms in patients with cognitive dysfunction was 2.12 times higher than that in the average population (OR=2.12, 95%CI: 1.56-2.89). The detection rate of depressive symptoms in patients with impaired instrumental activities of daily living (IADL) was 2.31 times (OR=2.31, 95%CI: 1.64-3.26) higher than that in the average population. Tea drinking (OR=0.73, 95%CI: 0.54-0.98) and physical exercise (OR=0.67, 95%CI: 0.49-0.90) seemed to be protective factors for depression in elderly MS patients (P<0.05). Conclusions: Older patients with MS and its component abnormalities have a higher risk of depression than the average population. Sleep disorders, cognitive impairment, and IADL impairment are important influencing factors for depression in elderly MS patients, while tea drinking and physical exercise may help to reduce the risk of the disease.

With the rapid development of computer technology, numerical simulation has gradually become an important method to study drying process and improve drying equipment. Using computer to simulate the drying process of traditional Chinese medicine(TCM) is characterized by intuitiveness, scientificity, and low cost, which serves as an auxiliary means for technical innovation in TCM drying. This paper summarizes the theories of different drying methods and the research status of numerical simulation in drying, introduces the modeling methods and software of numerical simulation, and expounds the significance of numerical simulation modeling in shortening the research and development cycle, improving drying equipment, and optimizing drying parameters. However, the current numerical simulation method for drying process has problems, such as low accuracy, lack of quantitative indicators for the control of simulation results on the process, and insufficient in-depth research on the mechanism of drug quality changes. Furthermore, this paper put forward the application prospect of numerical simulation in TCM drying, providing reference for the further study of numerical simulation in this field.

Establishment of treatment center for peritoneal metastasis in colorectal cancer / 中华胃肠外科杂志

The prognosis of patients with peritoneal metastasis from colorectal cancer is poor. At present, the comprehensive treatment system based on cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) has significantly improved the survival of these patients. However, CRS and HIPEC have strict indications, high procedural difficulty, and high morbidity and mortality. If CRS+HIPEC is performed in an inexperienced center, overall survival and quality of life of patients may bo compromised. The establishment of specialized diagnosis and treatment centers can provide a guarantee for standardized clinical diagnosis and treatment. In this review, we first introduced the necessity of establishing a colorectal cancer peritoneal metastasis treatment center and the construction situation of the diagnosis and treatment center for peritoneal surface malignancies at home and abroad. Then we focused on introducing our construction experience of the colorectal peritoneal metastasis treatment center, and emphasized that the construction of the center must be done well in two aspects: firstly, the clinical optimization should be realized and the specialization of the whole workflow should be strengthened; secondly, we should ensure the quality of patient care and the rights, well-being and health of every patient.

ConclusionThe combination of Gandouling decoction and CBT can ameliorate impulse control disorders in the WD patients with combined phlegm and stasis.

Polygalacin D inhibits the growth of hepatocellular carcinoma cells through BNIP3L-mediated mitophagy and endogenous apoptosis pathways / 中国天然药物

Platycodon grandiflorum (Jacq.) A. DC. is a famous medicinal plant commonly used in East Asia. Triterpene saponins isolated from P. grandiflorum are the main biologically active compounds, among which polygalacin D (PGD) has been reported to be an anti-tumor agent. However, its anti-tumor mechanism against hepatocellular carcinoma is unknown. This study aimed to explore the inhibitory effect of PGD in hepatocellular carcinoma cells and related mechanisms of action. We found that PGD exerted significant inhibitory effect on hepatocellular carcinoma cells through apoptosis and autophagy. Analysis of the expression of apoptosis-related proteins and autophagy-related proteins revealed that this phenomenon was attributed to the mitochondrial apoptosis and mitophagy pathways. Subsequently, using specific inhibitors, we found that apoptosis and autophagy had mutually reinforcing effects. In addition, further analysis of autophagy showed that PGD induced mitophagy by increasing BCL2 interacting protein 3 like (BNIP3L) levels.In vivo experiments demonstrated that PGD significantly inhibited tumor growth and increased the levels of apoptosis and autophagy in tumors. Overall, our findings showed that PGD induced cell death of hepatocellular carcinoma cells primarily through mitochondrial apoptosis and mitophagy pathways. Therefore, PGD can be used as an apoptosis and autophagy agonist in the research and development of antitumor agents.

Effects of Qingre Huoxue Jiedu Formula on Nerve Growth Factor-Induced Psoriasis / 中国结合医学杂志

OBJECTIVE@#To elucidate the mechanisms of 4 effective components from a Chinese medicine formula, namely Qingre Huoxue Jiedu Formula (QHJ heat- and toxin-clearing and blood-activating formula), in the treatment of nerve growth factor (NGF)-induced psoriasis.@*METHODS@#Keratinocyte proliferation and T cell proliferation models were developed using NGF. An NGF solution (NGF+DMEM, 100 ng/mL) was added to all induced groups and treated groups and were cultured for 24 h, while a solution with NTRK1 antagonist (K252a+DEME, 300 nmol/L) was added and cultured for 1 h. The models were used to evaluate the effects of the treatment with each of the 4 components of QHJ, namely shikonin, paeonol, astilbin and ursolic acid. Cell apoptosis and proliferation were measured by flow cytometry analysis and CCK8 assay, respectively. The mRNA expression levels of Bax, Bcl-xl, and NGF receptor (NGFR) were assessed by quantitative real-time PCR (qRT-PCR) and Western blot analysis, respectively.@*RESULTS@#(1) All QHJ-treated groups showed significantly increased cell apoptosis and inhibition of cell proliferation compared with the NGF-induced groups (P<0.05). In addition, treatment with QHJ plus NTRK1 significantly enhanced cell apoptosis and inhibition of cell proliferation compared with cells treated with QHJ only (P<0.05), particularly in cells treated with ursolic acid. (2) QHJ-treated groups showed higher protein expression levels of Bax, Bcl-xl compared with other groups (P<0.05). Additionally, treatment with QHJ plus NTRK1 significantly increased the protein expression levels of Bax, Bcl-xl and NGFR compared with those treated with QHJ only (all P<0.05), especially in those treated with shikonin.@*CONCLUSION@#The action mechanism of QHJ on psoriasis might be through enhancing cell apoptosis and inhibition of cell proliferation, and upregulating the expression level of Bax, Bcl-xl and NGFR.

Molecular identification and quality analysis of Rhei Rhizoma based on chloroplast matK gene and UPLC / 药学学报

Rhei Rhizoma is commonly used as a traditional Chinese medicine with multiple botanical origins. Different botanical sources may have different pharmacological activities. The germplasm resources of commercial Rhei Rhizoma were determined based on the chloroplast gene matK, and the anthraquinone and free anthraquinone content was determined by UPLC to analyze quality of commercial Rhei Rhizoma. Eighty-nine commercial Rhei Rhizoma samples were collected from 40 cities in 27 provinces. DNA was extracted and the matK gene was amplified by PCR. Results indicated that the collected samples were from the same botanical origin, Rheum palmatum, and 8 genotypes were identified, including Rp1, Rp2, Rp3, Rp4, Rp5, Rp6, Rp10 and Rp12. Rp4 and Rp6, cultivated in Gansu, Sichuan and Yunnan provinces were the main circulating genotypes, representing 40.45% and 37.08% of the total samples, respectively. Phylogenetic tree analysis showed that the eight genotypes were mainly divided into two branches, of which the main genotypes Rp4 and Rp6 were in one branch. Genetic distance analysis indicated that the genetic separation of the eight genotypes was between 0.001 and 0.010. UPLC analysis indicated that 93.26% of the samples met the Pharmacopoeia standards. There were significant differences in the content of total anthraquinone and free anthraquinone among the samples, in which the difference in free anthraquinone was 1.01% and the difference in total anthraquinone content was 3.79%, indicating that the quality of commercial Rhei Rhizoma samples varies considerably. There was no significant difference in the content of total anthraquinone and free anthraquinone in commercial Rhei Rhizoma among different collection provinces and genotypes. This study will help guide the circulation of Rhei Rhizoma in the market and provides valuable insights for molecular identification and quality analysis of other traditional Chinese medicines.

Cefiderocol: a novel siderophore cephalosporin against multi-drug resistant Gram-negative bacilli infections / 生物工程学报

Antimicrobial resistance is one of the critical public health issues in the world. There is an urgent need to develop effective broad-spectrum antibiotics to treat the infection of multi-drug resistant Gram-negative bacilli. Cefiderocol, developed by the Shionogi Inc. in Japan, is a new type of iron carrier cephalosporin antibiotics, which overcomes the drug resistance of Gram-negative bacilli due to the down-regulation of outer membrane pore protein and the up-regulation of efflux pump, and has good stability to serine- and metallo-carbapenemases. This drug has a broad spectrum and strong antibacterial activity against carbapenem-resistant Enterobacteriaceae (CRE), Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia. Cefiderocol can be used to treat complex urinary tract infections (including pyelonephritis), hospital-acquired pneumonia, and ventilator-associated pneumonia. By summarizing the chemical structure, antibacterial mechanism, in vitro antibacterial activity, pharmacokinetics, pharmacodynamics, and clinical treatment of cefiderocol, this review shows the application potential of cefiderocol as a new iron carrier cephalosporin in the treatment of multi-drug resistant Gram-negative bacilli infections.

Analysis of outcome indexes in randomized controlled trials of traditional Chinese medicine for rheumatic heart disease / 中国中药杂志

The present study analyzed the efficacy evaluation indexes of the randomized controlled trials(RCTs) of Chinese medi-cine in the treatment of rheumatic heart disease to lay the foundation for the construction of the corresponding core outcome index set. Clinical RCTs with a definite diagnosis of rheumatic heart disease were retrieved from CNKI, Wanfang, VIP, Sino Med, Pub Med, EMbase, and Cochrane Library from January 1, 2010, to December 31, 2020. Thirty-five RCTs were included, involving 3 314 patients and 41 efficacy evaluation indexes, which covered seven domains [traditional Chinese medicine(TCM) symptoms/syndromes, symp-toms/signs, physical and chemical examination, quality of life, long-term prognosis, economic evaluation, and safety events]. Physi-cal and chemical examination(56. 91%) and symptoms/signs(29. 27%) were the more frequently applied. The number of indexes used in a single trial ranged from 1 to 15, with an average of 4. The measurement time points of the top five indexes in the frequency of use were as follows: total response rate was reported at five measurement time points, ranging from 14 days to 6 months; left ventri-cular ejection fraction was measured at eight time points ranging from 5 days to 6 months; left ventricular end systolic diameter was measured at six time points, ranging from 5 days to 6 months; interleukin-2(IL-2) and tumor necrosis factor-α(TNF-α) were repor-ted 28 days after treatment. At present, there are many problems in the efficacy outcome indexes of RCTs in the treatment of rheumatic heart disease with TCM, such as large difference in quantity, unclear primary and secondary indexes, unreasonable selection of " surro-gate indexes", insufficient attention to long-term prognostic indexes and safety event indexes, non-standard application of composite in-dexes, long measurement period, and lack of TCM characteristics. It is urgent to establish the core outcome set for TCM treatment of rheumatic heart disease.

Research progress on role of traditional Chinese medicine in hepatic fibrosis based on miRNA-mediated activation of NLRP3 inflammasome / 中国中药杂志

In recent years, liver fibrosis has become a hotspot in the field of liver diseases. MicroRNA(miRNA)-mediated Nod-like receptor pyrin domain containing 3(NLRP3) inflammasome activation is pivotal in the pathogenesis of liver fibrosis. The present study mainly discussed the role of miRNA-mediated NLRP3 inflammasome activation in the pathogenesis of liver fibrosis. Different miRNA molecules regulated liver fibrosis by mediating NLRP3 inflammasome activation, including miRNA-350-3 p(miR-350-3 p)/interleukin-6(IL-6)-mediated signal transducer and activator of transcription 3(STAT3)/c-myc signaling pathway, miR-148 a-induced autophagy and apoptosis of hepatic stellate cells via hedgehog signaling pathway, miR-155-mediated NLRP3 inflammasome by the negative feedback of the suppressor of cytokine signaling-1(SOCS-1), miR-181 a-mediated downstream NLRP3 inflammatory pathway activation through mitogen-activated protein kinase kinase(MEK)/extracellular signal-regulated kinase(ERK)/nuclear transcription factor κB(NF-κB) inflammatory pathway, miR-21-promoted expression of NF-κB and NLRP3 of RAW264.7 cells in mice by inhibiting tumor necrosis factor-α inducible protein 3(A20), and miR-20 b-promoted expression of IL-1β and IL-18 by activating NLRP3 signaling pathway. Additionally, the anti-liver fibrosis mechanism of different active components in Chinese medicines(such as Curcumae Rhizoma, Glycyrrhizae Radix et Rhizoma, Aurantii Fructus, Polygoni Cuspidati Rhizoma et Radix, Moutan Cortex, Paeoniae Radix Alba, Epimedii Folium, and Cinnamomi Cortex) was also explored based on the anti-liver fibrosis effect of miRNA-mediated NLRP3 inflammasome activation.

Analysis of perioperative efficacy and safety of cytoreductive surgery in the treatment of colorectal cancer peritoneal metastases / 中华胃肠外科杂志

Objective: To analyzed perioperative safety of cytoreductive surgery (CRS) for patients with colorectal cancer peritoneal metastasis (CRPM) and to construct a predictive model for serious advese events (SAE). Methods: A descriptive case-series study was conducted to retrospectively collect the clinicopathological data and treatment status (operation time, number of organ resection, number of peritoneal resection, and blood loss, etc.) of 100 patients with peritoneal metastases from colorectal cancer or appendix mucinous adenocarcinoma who underwent CRS at the Sixth Affiliated Hospital of Sun Yat-sen University from January 2019 to August 2021. There were 53 males and 47 females. The median age was 52.0 (39.0-61.8) years old. Fifty-two patients had synchronous peritoneal metastasis and 48 had metachronous peritoneal metastasis. Fifty-two patients received preoperative neoadjuvant therapy. Primary tumor was located in the left colon, the right colon and the rectum in 43, 28 and 14 cases, respectively. Fifteen patients had appendix mucinous adenocarcinoma. Measures of skewed distribution are expressed as M (range). Perioperative safety was analyzed, perioperative grade III or higher was defined as SAE. Risk factors associated with the occurrence of SAEs were analyzed using multivariate logistic regression. A nomogram was plotted by R software to predict SAE, the efficacy of which was evaluated using the area under the ROC curve (AUC) and correction curves. Results: The median peritoneal cancer index (PCI) score was 16 (1-39). Sixty-eight (68.0%) patients achieved complete tumor reduction (tumor reduction score: 0-1). Sixty-two patients were treated with intraperitoneal hyperthermic perfusion chemotherapy (HIPEC). Twenty-one (21.0%) patients developed 37 SAEs of grade III-IV, including 2 cases of ureteral injury, 6 cases of perioperative massive hemorrhage or anemia, 7 cases of digestive system, 15 cases of respiratory system, 4 cases of cardiovascular system, 1 case of skin incision dehiscence, and 2 cases of abdominal infection. No grade V SAE was found. Multivariate logistic regression analysis showed that CEA (OR: 8.980, 95%CI: 1.428-56.457, P=0.019), PCI score (OR: 7.924, 95%CI: 1.486-42.259, P=0.015), intraoperative albumin infusion (OR: 48.959, 95%CI: 2.115-1133.289, P=0.015) and total volume of infusion (OR: 24.729, 95%CI: 3.956-154.562, P=0.001) were independent risk factors for perioperative SAE in CRS (all P<0.05). Based on the result of multivariate regression models, a predictive nomogram was constructed. Internal verification showed that the AUC of the nomogram was 0.926 (95%CI: 0.872-0.980), indicating good prediction accuracy and consistency. Conclusions: CRS is a safe and effective method to treat CRPM. Strict screening of patients and perioperative fluid management are important guarantees for reducing the morbidity of SAE.

Effect of Mitochondrial Function on Cell Senescence and Anti-ging Effect of Traditional Chinese Medicine and Moxibustion： A Review / 中国实验方剂学杂志

Since ancient times， delaying aging， health， and longevity have been the universal wish of people. Nowadays， China gives top strategic priority to the development of people's health. How to maintain a healthy life and slow down the aging of the human body is a problem worthy of our attention. Human aging can be shown as cell senescence from the microscopic level. Cell senescence is a process in which cell proliferation and differentiation and physiological function gradually decline. It is a normal physiological function responsible for the removal of damaged cells and is the regeneration and recovery of tissues after injury or acute stress. Aging is an irresistible natural law. Although it is inevitable， it is possible to delay aging. Energy metabolism is an important basis of cell function， in which cells use nutrients such as sugar and fat to produce adenosine triphosphate （ATP）. Mitochondria serve as the cell's power stations， where sugars， fats， and amino acids are eventually oxidized to release energy. Mitochondrial function decreases with age. Changes in mitochondrial dynamics， reactive oxygen species content， autophagy， and metabolites can cause dysfunction of electron transport chain and oxidative phosphorylation， and induce mitochondrial dysfunction. Mitochondrial dysfunction is one of the internal causes of many aging-related diseases， such as neurodegenerative diseases， Alzheimer′s disease， and atherosclerosis. Chinese medicine with few side effects and rich ingredients and health care moxibustion with safety and efficacy have been widely applied to the field of anti-aging. This study reviewed the effect of mitochondrial function on cell senescence， and retrieved， analyzed， and summarized research papers on the mechanism of traditional Chinese medicine （TCM） and moxibustion in delaying aging by affecting mitochondrial function， which is expected to provide new insights for further research in this field.

Identification and quality evaluation of germplasm resources of commercial Scutellaria baicalensis based on DNA barcode and HPLC / 中国中药杂志

Scutellaria baicalensis is a commonly used Chinese medicinal herb. In this study, we identified the germplasm resources of commercial S. baicalensis samples based on trnH-psbA, petA-psbJ, and ycf4-cemA sequences according to the available chloroplast genome sequencing results, and measured the content of baicalin by HPLC. Through the above means we determined the best DNA barcode that can be used to detect the germplasm resources and evaluate the quality of commercial S. baicalensis samples. A total of 104 samples were collected from 24 provinces, from which DNA was extracted for PCR amplification. The amplification efficiencies of trnH-psbA, petA-psbJ, and ycf4-cemA sequences were 100%, 59.62%, and 25.96%, respectively. The results of sequence analysis showed that 5, 4, and 2 haplotypes were identified based on trnH-psbA, petA-psbJ, and ycf4-cemA sequences, respectively. However, the sequences of haplotypes in commercial samples were different from that of the wild type, and the joint analysis of three fragments of S. baicalensis only identified 6 haplotypes. Furthermore, the phylogenetic analysis and genetic distance analysis indicated that trnH-psbA could be used to identify S. baicalensis from adulterants. The above analysis showed that trnH-psbA was the best fragment for identifying the germplasm resources of commercial S. baicalensis samples. We then analyzed the haplotypes(THap1-THap5) of commercial S. baicalensis samples based on trnH-psbA and found that THap2 was the main circulating haplotype of the commercial samples, accounting for 86.55% of the total samples, which indicated the scarce germplasm resources of commercial S. baicalensis samples. The content of baicalin in all the collected commercial S. baicalensis samples exceeded the standard in Chinese Pharmacopoeia and had significant differences(maximum of 12.21%) among samples, suggesting that the quality of commercial S. baicalensis samples varied considerably. However, there was no significant difference in baicalin content between different provinces or between different haplotypes. This study facilitates the establishment of the standard identification system for S. baicalensis, and can guide the commercial circulation and reasonable medication of S. baicalensis.

Global centennial research and the internationalization of acupuncture and moxibustion: in the perspective of SCI database (1921-2020) / 中国针灸

The paper retrieves and analyzes SCI articles on acupuncture-moxibustion published in the world from 1921 to 2020. It is found that the overall growth of SCI articles on acupuncture-moxibustion in both China and global countries is increasing, and the proportion of publication amount in China is increased gradually. It is believed that the articles on acupuncture-moxibustion researches from 1921 to 2020 in the world collected in SCI database indicate three stages, i.e. scattered publication, internationalization and great contribution on acupuncture-moxibustion in TCM. The paper investigates the first SCI article on acupuncture-moxibustion in the world and in China respectively and analyzes the main disciplines, research institutions and journal distribution, as well as the highly cited articles in the global countries. It is proposed that acupuncture-moxibustion research in China should reflect the academic ideological characteristics of acupuncture-moxibustion in TCM, develop the interdisciplinary research and deepen the cooperation with high-level scientific institutions so as to improve the international academic influence of acupuncture-moxibustion in TCM.
