This study was aimed to discuss the ways of converting clinical data entered in the Case Report Form (CRF) to Study Data Tabulation Model (SDTM) database format in clinical research of traditional Chinese medicine (TCM). Currently, there were three approaches for implementing SDTM, which were the pure SDTM approach, submission-only approach and database-only approach. This article compared and analyzed advantages and disadvantages of three approaches and introduced experiences of the Clinical Evaluation Center of China Academy of Chinese Medical Sciences using database-only approach for SDTM implementation. The results showed that pure SDTM approach can maximally embrace SDTM standards. However, the current process and software system should be modified. Therefore, it was time-consuming and expensive. The submission-only approach was the most economic way in the application of SDTM standards. However, the data quality and traceability may not be guaranteed. The database-only approach built the study database based on the SDTM standard by writing transformed program before data entry while the data collection system was not SDTM-compatible. It was concluded that database-only approach for implementation SDTM was a suitable and practical way to TCM clinical research.

All items retrieved were selected and modified by experts interview and a pilot study in patients with stroke. Then, a clinical nursing swallowing assessment tool (CNSAT) was formulated.ResultsTotally, seven items of symptoms and signs related to dysphagia in patients with stroke were found with literature review. All the seven items retrieved were selected again by experts interview and finally a CNSAT was formed with six modified items by a pilot study in 10 patients with stroke, each item with four choice based on its severity of their symptoms and signs.ConclusionCNSAT is a simple, convenient and safe instrument and suitable for nurses to assess swallowing function of patients with stroke.

The goal of treatment of metabolic syndrome is the prevention of diabetes and cardiovascular events. A series of novel tetrahydrocoptisine quaternary ammonium compounds were prepared to evaluate their action of hypoglycemia and hypolipidemia for finding the therapeutic agents of metabolic syndrome. Starting from the coptisine hydrochloride (2), fifteen target compounds were synthesized by reduction and substitution of the 7-N position. All of the target compounds were characterized by 1H NMR and HR-MS. Their hypoglycemic activities were evaluated in HepG2 cell and hypolipidemic activities of compounds with better hypoglycemic activity were tested further in vivo. Results indicated that compounds 5, 7, 8 and 9 exhibited better hypoglycemic activities in vitro and compounds 5 and 8 exhibited good hypolipidemic activities in high-fat-diet (HFD) induced hyperlipidemia mice and (or) hamsters. However, the activity is not as good as simvastatin.

Chronic lung diseases, including bronchial asthma, chronic obstructive pulmonary disease (COPD), chronic bronchitis, allergic rhinitis and repeated respiratory tract infection (RRTL) in infants, exacerbate frequently in winter because of respiratory viral infections and low temperature. Summer acupoint application therapy (SAAT) is thought to be effective in reducing exacerbation frequency of chronic lung diseases in winter. It is a kind of therapy using a herbal mixture for external application on special acupoints during summer. The herbal mixture basically contains Semen Sinapis Albae, Herba Asari, Radix Euphorbiae Kansui and Rhizoma Corydalis. The acupoints include Feishu (BL13), Dazhui (GV14) and Danzhong (CV17). Through a large-scale multicenter trial based on three years of clinical observation, and retrospective and prospective analyses, this study aims to explore the efficacy of SAAT.

Aim To investigate the effect of DHA on NGF-induced neuronal differentiation of PC12 cells and explore the possible mechanism via regulating BMP pathway. Methods PC12 cells were treated with 100μg·L-1 NGF and 100 μg·L-1 NGF + 10 μmol· L-1 DHA for 3, 6 and 9 days respectively. The length and number of neurite were detected by immunofluores-cenc. DHA content was analyzed by gas chromatogra-phy in all groups. The protein expression of BMP4, BMP7 , BMPR-II and p-Smad 1/5/8 was determined by Western blot. Results The length of total primary neurite in NGF+DHA groups was obviously increased, longer than that in NGF group; DHA content in 10μmol · L-1 DHA group was higher than that in the control group;NGF+DHA groups also unregulated the protein expression of BMP4 , BMP7 , BMPR-II and p-Smad 1/5/8 . Conclusion DHA promotes NGF-in-duced neuronal differentiation in PC12 cells, which may be associated with the upregulation of BMP path-way protein.

Objective:To investigate the possible role and mechanism of purinergic ligand-gated ion channel 7(P2X7)/nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3) inflammasome pathway in cognitive impairment induced by sleep deprivation (SD)mice.Methods:SPF grade male C57BL / 6J mice aged 6-8 weeks were randomly divided into 3 groups according to the random number table method with 6 mice in each group.They were normal control group (CC group), SD group and SD+ P2X7 receptor antagonist brilliant blue G(BBG) group (SD+ BBG group). Modified multiple platform method was used to establish a 5-day SD model in mice.During the SD intervention period, the mice in SD+ BBG group were injected with BBG(50 mg/kg) intraperitoneally once a day, while the mice in CC group and SD group were injected with the same volume of 0.9% sodium chloride solution.Morris water maze was conducted to evaluate the cognitive function of mice.The protein expression levels of P2X7, NLRP3, caspase-1, apoptosis-associated proteins(ASC) and interleukin-1β(IL-1β) in hippocampus were detected by Western blot.RT-qPCR was used to detect the mRNA expression levels of tumor necrosis factor-α(TNF-α), IL-1β, interleukin-18(IL-18) and microglial polarization surface markers CD206 and CD86 in hippocampus.Graph pad Prism 8.0 software and SPSS 25.0 software were used for statistical analysis and mapping.Results:(1) The interaction effect between time and groups of escape latency in three groups of mice was significant ( F=15.76, P<0.001). From the 2nd to 5th day, the escape latencies of mice in SD group were higher than those of CC group, while the escape latencies of mice in SD+ BBG group were lower than those of SD group (all P<0.05). (2)The results of the space exploration experiment showed that there were statistically significant differences in target quadrant residence time and the times of crossing the platform( F=6.65, P=0.009; F=12.39, P<0.001). The target quadrant residence time ((23.42±0.55) s) and times of crossing the platform ((17.67±0.71) times) of the SD group were both lower than those of the CC group ((29.48±1.78) s, (23.33±0.95) times) (both P<0.05), while the target quadrant residence time ((28.62±1.19) s) and the times of crossing the platforms ((21.33±0.76) times) of the SD+ BBG group were both higher than those of the SD group (both P<0.05). (3)There were statistically significant differences in the protein levels of inflammatory related proteins such as P2X7, NLRP3, caspase-1, ASC and IL-1β in the hippocampus of mice among the 3 groups( F=8.23, 8.97, 8.45, 54.42, 8.12, all P<0.05). Compared with CC group, the protein levels of P2X7 ((0.93±0.02), (0.71±0.04)), NLRP3 ((0.97±0.04), (0.62±0.09)), caspase-1 ((1.00±0.03), (0.76±0.07)), ASC ((0.96±0.02), (0.77±0.04)) and IL-1β ((0.85±0.07), (0.54±0.04)) in SD group were all higher (all P<0.05). Compared with SD group, the protein levels of P2X7 (0.74±0.05), NLRP3 (0.78±0.02), caspase-1 (0.74±0.04), ASC (0.67±0.02), IL-1β (0.53±0.07) in SD+ BBG group were all lower (all P<0.05). (4)There were statistically significant differences in the mRNA levels of IL-18, IL-1β, TNF-α, CD86 and CD206 in hippocampus among the three groups ( F=12.80, 12.28, 105.80, 7.06, 30.19, all P<0.05). The mRNA levels of IL-18, IL-1β, TNF-α, CD86 in SD group were all higher than those in CC group(all P<0.05), while the mRNA level of CD206 in SD group was lower than that in CC group( P<0.05). Compared with SD group, the mRNA levels of IL-18, IL-1β, TNF-α, CD86 were lower in SD+ BBG group (all P<0.05), while the CD206 mRNA level of SD+ BBG group was higher than that in SD group( P<0.05). Conclusion:SD intervention can lead to cognitive impairment and increased expression of P2X7 in hippocampus of mice, which may be related to the activation of P2X7/ NLRP3 inflammasome signaling pathway, promoting the polarization of microglia into pro-inflammatory type and up-regulating the expression of pro-inflammatory cytokines.Inhibition of P2X7 can improve the cognitive function of mice.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

Objective: To evaluate the impact of motivational interviewing (MI) on the illness perception in patients after percutaneous coronary intervention (PCI). Methods: Totally 160 patients after PCI were randomly divided into two groups. The patients in the control group (n=85) received routine education, while patients in the intervention group (n=75) were received 4 times MI (during hospitalization, before discharge, 1 month after discharge, 3 months after discharge), 20 min for each time. Illness perception was appraised before and after the intervention in both groups. Results: The mean scores of illness perception in the intervention group, including symptom perception, disease perception and cause perception, were 5.85±1.75, 3.65±0.66, 2.85±0.30, which were significantly higher than that of the control group after the intervention, 4.84±1.09, 2.92±0.61, 2.48±0.31, the differences were significantly statistical (t=2.248, 3.717, 3.926, all P<0.05). Conclusions MI is much more effective than routine education on the improvement of illness perception in patients after PCI.

Restless legs syndrome (RLS) is a kind of common diseases of the nervous system, of which adult prevalence rate is from 1% to 15%. The etiology, pathogenesis and related gene therapy of RLS are not fully understood. Studies have shown that RLS may be associated with the polymorphism of some risk genes. Genome-wide association studies have revealed a total of seven risk sites to date, including MEIS1, BTBD9, MAP2K5/SKOR1, PTPRD, TOX3, NOS1 and 2p14 intergenic regions. This article reviewed the research progress of single nucleotide polymorphisms in RLS risk genes in recent years.

Objective:To investigate the characteristics of transcranial sonography (TCS) in patients with restless legs syndrome (RLS), and analyze the correlations of scores of RLS Self-rating Severity Scale by International Restless Leg Syndrome Study Group (IRLS) and TCS parameters with clinical data of these patients.Methods:Twenty-one patients with RLS admitted to the Sleep Disorder Clinic of our hospital from September 2020 to January 2021 were selected as RLS group, and 23 healthy controls at the same time period were recruited as control group. IRLS was used to evaluate the severity of patients in the RLS group, and the 14-item Hamilton anxiety rating scale (HAMA-14) and 24-item Hamilton depression rating scale (HAMD-24) were used to evaluate the anxiety and depression of subjects from the 2 groups. Pittsburgh Sleep Quality Scale (PSQI), Insomnia Severity Index (ISI) and Epworth Sleepiness Scale (ESS) were used to evaluate the sleep quality of subjects from the 2 groups. TCS was used to examine the occurrence of hypoechoic substantia nigra and raphe nucleus rupture and the width of the third ventricle in the two groups. The clinical data and TCS parameters of patients in the 2 groups were compared, and the correlations of IRLS scores and TCS parameters with clinical features of patients in the RLS group were analyzed.Results:As compared with those in the control group, the HAMA-14, HAMD-24, ISI and PSQI scores in the RLS group were statistically higher ( P<0.05). As compared with the control group, RLS group had significantly higher proportion of patients with hypoechoic substantia nigra or raphe nucleus rupture ( P<0.05). In RLS patients, the IRLS scores were positively correlated with HAMA-14, HAMD-24, and ISI scores ( P<0.05); ESS scores were negatively correlated with hypoechoic substantia nigra and width of the third ventricle ( rs=-2.005, P=0.045; r=-0.477, P=0.029); width of the third ventricle was negatively correlated with gender (male) and years of education ( rs=-0.592, P=0.005; r=-0.627, P=0.002), and positively correlated with age and course of the disease ( r=0.756, P<0.001; r=0.167, P=0.047). Conclusions:Patients with RLS are prone to anxiety, depression and sleep disorders; their TCS shows hypoechoic substantia nigra and raphe nucleus rupture. RLS severity may affect HAMA-14, HAMD-24, and ISI scores. Gender, age, years of education, course of disease, and ESS scores of RLS patients may affect TCS related parameters.
