OBJECTIVES: To report the development, validation, and findings of the Multi-dimensional Attention Rating Scale (MARS), a self-report tool crafted to evaluate six-dimension attention levels. METHODS: The MARS was developed based on Classical Test Theory (CTT). Totally 202 highly educated healthy adult participants were recruited for reliability and validity tests. Reliability was measured using Cronbach's alpha and test-retest reliability. Structural validity was explored using principal component analysis. Criterion validity was analyzed by correlating MARS scores with the Toronto Hospital Alertness Test (THAT), the Attentional Control Scale (ACS), and the Attention Network Test (ANT). RESULTS: The MARS comprises 12 items spanning six distinct dimensions of attention: focused attention, sustained attention, shifting attention, selective attention, divided attention, and response inhibition.As assessed by six experts, the content validation index (CVI) was 0.95, the Cronbach's alpha for the MARS was 0.78, and the test-retest reliability was 0.81. Four factors were identified (cumulative variance contribution rate 68.79%). The total score of MARS was correlated positively with THAT (r = 0.60, P < 0.01) and ACS (r = 0.78, P < 0.01) and negatively with ANT's reaction time for alerting (r = -0.31, P = 0.049). CONCLUSIONS The MARS can reliably and validly assess six-dimension attention levels in real-world settings and is expected to be a new tool for assessing multi-dimensional attention impairments in different mental disorders.

The inheritance, innovation, and development of traditional Chinese medicine(TCM) need to be based on Chinese medicinal materials. The TCM seed industry is the source of TCM production, which is related to the stable supply and quality safety of TCM. This paper summarizes the basic situation of the TCM seed industry and introduces relevant policies and regulations to TCM seeds in the seed industry and the TCM field. At present, the Management Measures of TCM Seeds and Seedlings has not yet promulgated, and TCM seeds are classified as non-major crops in the category of crops for management. This paper also describes the current situation of TCM seed and seedling system construction, which is in the development stage, from six aspects, including the construction of TCM seed industry technical support system; the establishment of TCM seed standard; the construction of germplasm resource preservation system; TCM seed testing, variety registration, and variety protection; production and management of TCM seeds; TCM seed supervision. According to the development status of the TCM seed industry, four problems are put forward, including imperfect systems and standards relevant to TCM seeds, insufficient supervision and law enforcement regarding TCM seeds, insufficient policy measures and capital investment to promote the development of the industry, and the industry's falling into a low-level cycle.Accordingly, four suggestions are provided, including improving laws, regulations, and policies, perfecting standards and norms,strengthening supervision and law enforcement, and promoting support system construction, in order to boost the high-quality development of the TCM seed industry.

OBJECTIVE To investigate the mechanism of catalpol affecting the differentiation of helper T cell 17 （Th17） by interfering the expressions of pyruvate kinase M2 （PKM2） and lactate dehydrogenase A （LDHA）. METHODS The naive CD4+ T cells were selected from the spleen of C57BL/6 mice， and were differentiated into Th17 cells by adding directional differentiation stimulants for 72 hours. At the same time， the cells were treated with 0 （directed control）， 20， 40 and 80 μg/mL catalpol. The flow cytometry was used to detect the proportion of Th17 cell differentiation in cells； the colorimetric method was adopted to detect the levels of pyruvate and lactate in cell culture supernatant； mRNA expressions of retinoid-related orphan nuclear receptor gamma t （RORγt）， PKM2 and LDHA were detected by qRT-PCR method； Western blot was used to detect the expression levels of PKM2， LDHA， signal transducer and activator of transcription 3 （STAT3）， and phosphorylated STAT3 （p-STAT3） proteins in cells. RESULTS Compared with the directed control group， after 72 hours of treatment with 20， 40， 80 μg/mL catalpol， the differentiation ratio of Th17 cells were decreased by 6.74%， 8.41%， 9.24%， and the levels of pyruvate and lactate in the cell culture supernatant， the mRNA expressions of PKM2， LDHA and RORγt as well as the protein expressions of PKM2 and LDHA and the phosphorylation of STAT3 were significantly reduced （P＜0.05）. CONCLUSIONS Catalpol can reduce the glycolysis level by down-regulating the expressions of PKM2 and LDHA， thereby inhibiting the differentiation of Th17 cells.

The use of tyrosine kinase inhibitors （TKI） has been an important advance in the systemic treatment of hepatocellular carcinoma， but their sustained anti-angiogenic therapy leads to increased tumor hypoxia， accelerates the development of a hypoxic microenvironment and promotes the expressions of hypoxia-inducible factors （HIF）， thereby inducing drug resistance of tumor patients to TKI. This paper summarizes the mechanism of action of HIF mediating TKI resistance in hepatocellular carcinoma in aspects of metabolic reprogramming， abnormal expressions of cancer and cancer-associated genes， and ferroptosis， and sorts resistance response strategies to provide reference for clinical solutions to TKI resistance issues. As results show， HIF/ glycolysis axis inhibitors （isoflavonoid genistein， simvastatin， etc.） can improve TKI resistance based on metabolic reprogramming mechanism； oncogene-targeted inhibitors combined with TKI （the combination of capsaicin and sorafenib） can improve TKI resistance based on abnormal expression of cancer and cancer-related genes； fatty acid synthase inhibitor （orlistat） can improve TKI resistance based on ferroptosis mechanism.

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.

Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34⁺⁰ weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

OBJECTIVE To evaluate the clinical effectiveness and safety of domestic generic and imported original clopidogrel for antiplatelet therapy in patients with acute coronary syndrome （ACS）. METHODS The clinical data of ACS patients in Nanjing Drum Tower Hospital of China Pharmaceutical University from January 2020 to June 2021 were retrospectively collected by using electronic medical record system， and the patients were divided into original drug group （321 cases） and generic drug group （328 cases） according to the drug use. Both groups were given dual antiplatelet therapy with clopidogrel and aspirin. The effectiveness and safety outcomes of the two groups were followed up for 12 months and compared， the related influential factors were analyzed. RESULTS Major adverse cardiovascular events （MACE） occurred in 16 and 22 patients in original drug group and generic drug group respectively， including nonfatal myocardial infarction （4 and 5 cases）， stroke （2 and 4 cases）， revascularization （8 and 3 cases）， cardiovascular related death （2 and 4 cases）， and all-cause death （4 and 6 cases）. There were 12 and 7 patients with major bleeding events， 38 and 29 patients with minor bleeding events， and 33 and 21 patients with non-bleeding adverse events. There was no statistically significant difference in the cumulative incidence of related events （P values of Log-Rank tests were all greater than 0.05）. Cox regression analysis showed that the use of generic clopidogrel did not increase the risk of MACE and major bleeding events in ACS patients [hazard ratio of 1.305 and 0.416， 95% confidence interval of （0.678， 2.512） and （0.155， 1.117）， respectively， P＞0.05]， and the combination of proton pump inhibitors （PPI） could reduce the risk of major bleeding events [hazard ratio of 0.196， 95% confidence interval of （0.063， 0.611）， P＜0.05]. CONCLUSIONS Compared with imported original drug， domestic generic clopidogrel has similar clinical effectiveness and good safety. Combined use of PPI may be a beneficial factor to reduce the occurrence of major bleeding events in patients.

Objective: At present, though the laparoscopic delta-shaped anastomosis and overlapping delta-shaped anastomosis have been gradually applied to complete laparoscopic radical resection of left hemicolon cancer, the comparative evaluation of their efficacy has not been mentioned in the published literatures. This study aims to explore the safety, feasibility and short-term efficacy of overlapping delta-shaped anastomosis (ODA) in totally laparoscopic left hemicolectomy. Methods: A retrospective cohort study was performed. The clinical and pathological data of patients who underwent totally laparoscopic left hemicolectomy at Department of Colorectal Surgery, Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from May 2017 to October 2020 were retrospectively analyzed. The case inclusion criteria were as follows: (1) age of 18-75 years; (2) body mass index (BMI) of 18.5-30 kg/m(2); (3) descending colonic and proximal sigmoid colonic adenocarcinoma was confirmed by preoperative colonoscopy and pathology. The exclusion criteria: (1) multiple primary colorectal cancers; (2) uncontrolled or poorly controlled diabetes mellitus, immune system diseases, or hematological diseases; (3) severe intestinal obstruction; (4) left transverse colonic or splenic flexure colonic adenocarcinoma; (5) distant metastasis of liver, lung and other viscera determined by enhanced computed tomography in the chest, abdomen and pelvis. According to the above criteria, a total of 115 patients with left hemicolon cancer were enrolled. All the patients underwent totally laparoscopic left hemicolectomy. Patients who underwent laparoscopic traditional delta-shaped anastomosis were selected as the control group. Patients who underwent laparoscopic ODA were selected as the ODA group. Effects of these two laparoscopic reconstruction methods on postoperative recovery and perioperative complications were analyzed and compared. Results: A total of 60 patients were enrolled in the ODA group, including 32 males and 28 females, with mean age of (57.3±10.4) years and body mass index (BMI) of (25.0±3.1) kg/m(2). While mean 55 patients were enrolled in the control group, including 31 males and 24 females, with mean age of (56.7±9.9) years and BMI of (24.4±2.9) kg/m(2). There was no statistically significant differences between the two groups in gender, age, BMI, American Society of Anesthesiologist (ASA) classification, TNM staging, preoperative abdominal surgery history, neoadjuvant chemotherapy and nutritional status (levels of hemoglobin, lymphocyte count, prealbumin, and albumin) (all P>0.05). All the patients in both groups received R0 resection without conversion to open laparotomy or conversion to extra-abdominal anastomosis. The digestive tract reconstruction time of the ODA group was significantly shorter than that of the control group [(15.1±1.7) minutes vs. (15.9±2.4) minutes, t=-2.053, P=0.042]. There were no statistically significant differences in the total operation time, intraoperative blood loss, length of skin incision, tumor size, proximal and distal margins, harvested lymph nodes, postoperative first ambulatory time, and postoperative hospital stay (all P>0.05). However, the time to the first flatus and the first defecation in the ODA group was significantly shorter as compared to control group [(1.5±0.5) days vs. (1.7±0.5) days, t=-2.028, P=0.045; (3.1±0.6) days vs. (3.4±0.7) days, t=-2.095, P=0.039], indicating faster intestinal function recovery in patients with ODA. The morbidity of postoperative complication was 6.7% (4/60) in the ODA group and 7.3% (4/55) in the control group and no significant difference was found (χ(2)=0.016, P=0.898). Two cases of incision infection, 1 case of lung infection, and 1 case of intra-abdominal infection occurred in the ODA group, while 3 cases of lung infection and 1 case of intra-abdominal infection occurred in the control group. All these complications were resolved after conservative treatment, and no secondary operation was performed due to complications. Conclusion: Compared with the traditional delta-shaped anastomosis, ODA is associated with a faster recovery of postoperative intestinal function without increasing the morbidity of postoperative complications, and has the satisfactory short-term efficacy.

Objective: Moxifloxacin (MFX) shows good activity against and can be a possible antibiotic therapy to treat infection; however, other studies have shown a lower or no activity. We aimed to evaluate MFX activity against using zebrafish (ZF) model . Methods: A formulation of labeled with CM-Dil was micro-injected into ZF. Survival curves were determined by recording dead ZF every day. ZF were lysed, and colony-forming units (CFUs) were enumerated. Bacteria dissemination and fluorescence intensity in ZF were analyzed. Inhibition rates of MFX and azithromycin (AZM, positive control) were determined and compared. Results: Significantly increased survival rate was observed with different AZM concentrations. However, increasing MFX concentration did not result in a significant decrease in ZF survival curve. No significant differences in bacterial burdens by CFU loads were observed between AZM and MFX groups at various concentrations. Bacterial fluorescence intensity in ZF was significantly correlated with AZM concentration. However, with increasing MFX concentration, fluorescence intensity decreased slightly when observed under fluorescence microscope. Transferring rates at various concentrations were comparable between the MFX and AZM groups, with no significant difference. Conclusion MFX showed limited efficacy against using ZF model. Its activity needs to be confirmed.
