OBJECTIVE@#To assess the outcomes after acupoint application in patients with pharyngeal pain in a real-world settings, and analyze the characteristics of effective population and prescription characteristics of acupoint application.@*METHODS@#Based on CHUNBO platform, patients with pharyngeal pain who were candidates for acupoint application on the basis of physician-evaluation, were enrolled in a nationwide, prospective, 69-week multicenter observational study from August 2020 to February 2022. Propensity score matching (PSM) was used to match the confounding factors and the association rules were used to analyze the characteristics of effective population and prescription characteristics of acupoint application. Outcome assessments included the disappearance rate of pharyngeal pain (within 3, 7, and 14 days), disappearance time of pharyngeal pain, as well as adverse events.@*RESULTS@#Of 7,699 enrolled participants, 6,693 (86.9%) received acupoint application and 1,450 (21.7%) with non-acupoint application. After PSM, there were 1,004 patients each in the application group (AG) and non-application group (NAG). The disappearance rate of pharyngeal pain in the AG at 3, 7, and 14 days were all higher than those in the NAG (P<0.05). The disappearance time of pharyngeal pain in the AG were shorter than that in the NAG (logrank P<0.001, hazard ratio=1.51, 95% confidence interval: 1.41-1.63). The median age of effective cases was 4 years, mainly 3-6 years old (40.21%). The disappearance rate of pharyngeal pain in the application group with tonsil diseases was 2.19 times higher than that in the NAG (P<0.05). The commonly used acupoints for the effective cases were Tiantu (RN 22), Shenque (RN 8) and Dazhui (DU 14). The commonly used herbs for the effective cases were Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae. Among them, Natrii sulfas was applied to RN 8 most frequently (support 84.39%). A total of 1,324 (17.2%) patients experienced AEs, and mainly occurred in the AG, with significant difference in the incidence of AEs between goups (P<0.05). All AEs reported were the first grade, and the average regression days of AEs was 2.8 days.@*CONCLUSIONS@#Acupoint application in patients with pharyngeal pain resulted in improved effective rate and shortened duration, especially children aged 3-6 years old, and those with tonsil diseases. Acupoint of RN 22, RN 8 and DU 14, Natrii sulfas, Radix et Rhizoma Rhei, and Herba Ephedrae were the most commonly used herbs in the treatment of pharyngeal pain.

Determination of 27 volatile organic compounds in exhaled breath by thermal desorption-gas chromatography-mass spectrometry / 环境与职业医学

Background Volatile organic compounds (VOCs) in exhaled breath are closely associated with respiratory diseases and are linked to various metabolic reactions in the human body. A quantitative analytical method can provide technical support for studying VOCs related to various diseases. Objective To establish a thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) method for the determination of 27 VOCs in exhaled breath. Methods VOCs in exhaled breath were collected using a Bio-VOC sampler and enriched with Tenax TA thermal desorption tubes before TD-GC-MS analysis. Standards were collected using thermal desorption tubes and optimized for thermal desorption conditions as well as chromatographic and mass spectrometric conditions: The separation of the 27 VOCs was achieved by an optimized temperature program, the improvement of sensitivity by optimizing quantitative ions, and the increase of VOCs desorption efficiency by optimizing thermal desorption time and temperature. Limit of detection, limit of quantification, accuracy, precision, and stability of the proposed method were investigated by spiking with a blank gas bag, and exhaled breath samples from 20 healthy individuals were collected for an application study of the proposed method. Results The thermal desorption temperature was 280 ℃, and desorption time was 6 min. A VF-624ms chromatographic column was selected for the separation of target substances. The initial temperature of heating program was 35 ℃, maintained for 1 min, and then increased to 100 ℃ at a heating rate of 3 ℃·min−1 for 1 min, followed by increasing to 210 ℃ at a heating rate of 28 ℃·min−1 for 5 min. A quantitative analysis was conducted with a single ion monitoring (SIM) mode. Under these conditions, the 27 VOCs showed good linear relationships in their respective concentration ranges and the correlation coefficients were higher than 0.9990. The limits of detection of the method were in the range of 0.01-0.13 nmol·mol−1, the limits of quantification were in the range of 0.02-0.44 nmol·mol−1, and the spiked recoveries were in the range of 80.1%-120.5%, with intra-batch and inter-batch precision ≤ 18.8% and 17.9% respectively. All substances can be stored at room temperature (23-28 °C) for 7 d and at 4 °C for 14 d. The proposed method was applied to exhaled breath samples from 20 subjects with detection rates≥ 80% (except for trans-2-pentene and decane) and a concentration range of 0.00-465.50 nmol·mol−1. Conclusion The established TD-GC-MS method for quantification of VOCs in exhaled breath is characterized by high sensitivity and good accuracy, and is suitable for quantitative determination of VOCs in exhaled breath, which can provide technical support for the study of exhaled breath VOCs.

Thyroxine promotes the progression of integrin α vβ 3-positive differentiated thyroid cancer through the ERK1/2 pathway / 中华核医学与分子影像杂志

Objective:To explore whether thyroxine (T 4) could promote differentiated thyroid cancer (DTC) progression by binding to integrin α vβ 3in vitro and its downstream mechanism. Methods:Papillary thyroid cancer cell lines TPC-1, K1 and follicular thyroid cancer (FTC) cell line FTC133 were cultured in vitro, and the expressions of integrin α vβ 3 in those 3 DTC cell lines were determined with immunofluorescence and flow cytometry analysis. After the treatment of T 4, tetraiodo thyroacetic acid (Tetrac) and Arg-Gly-Asp (RGD) peptide alone or in combination, the proliferation and metastatic potential of DTC cell lines were detected by cell counting kit-8 (CCK-8), Transwell migration and invasion assays. The small interfering RNA (siRNA) transfection was used to verify whether integrin α v or β 3 subunit knockdown could reverse the effect of T 4 on DTC cells. The expression levels of downstream signaling proteins phosphorylated extracellular signal-regulated kinase (p-ERK)1/2 and total extracellular signal-regulated kinase (ERK)1/2 were detected by Western blot. The effects of mitogen-activated protein kinase kinase (MEK)1/2 inhibitor (GSK1120212) on the proliferation, migration and invasion of T 4-treated cells were detected. One-way analysis of variance and Tukey test were used for data analysis. Results:The integrin α vβ 3 expressions in TPC-1, K1 and FTC133 cells were all positive, with the relative mean fluorescence intensity (MFI) of 61.93±18.61, 16.89±2.43 and 32.36±0.83, and the percentages of positive cells of (94.38±1.30)%, (74.11±3.87)% and (50.67±1.78)%, respectively ( F values: 13.36 and 217.30, P=0.006 and P<0.001). Compared with control group, the proliferation, migration and invasion in the three DTC cell lines treated with T 4 were significantly enhanced (96 h, F values: 62.67-297.50, q values: 13.15-20.73, all P<0.001). T 4-induced cell proliferation, migration and invasion were markedly reversed by Tetrac or RGD (96 h, q values: 8.61-17.54, all P<0.001). T 4-induced cell proliferation, migration and invasion were also significantly inhibited by the knockdown of integrin α v or β 3 subunit (72 h, F values: 7.75-70.98, q values: 4.77-15.21, all P<0.05). Western blot results showed that the phosphorylation levels of ERK1/2 in DTC cells were significantly increased by T 4 treatment, and the T 4-induced activation of ERK1/2 signaling pathway could be blocked by Tetrac, RGD, integrin α v or β 3 subunit knockdown. T 4-induced cell proliferation, migration and invasion were significantly reversed by GSK1120212 (96 h, F values: 47.53-151.40, q values: 10.32-16.65, all P<0.001). Conclusion:T 4 can promote cell proliferation and metastasis of DTC cells by binding to integrin α vβ 3 and activating the ERK1/2 pathway.

Correlation of telomere length of bone marrow mononuclear cells with relapse after allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia / 白血病·淋巴瘤

Objective:To investigate the relationship between telomere length of bone marrow mononuclear cells and prognosis of patients with acute myeloid leukemia (AML) who received allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:Telomere length of bone marrow mononuclear cells before transplantation, after transplantation and before donor mobilization as well as information related to follow-up of 33 AML patients who received allo-HSCT in the Affiliated Hospital of Guizhou Medical University between June 2020 and June 2021 were retrospectively analyzed. Telomere length was detected by using telomeric terminal restriction fragment (TRF) method. Telomere length was compared among patients with different prognoses. The recurrence within 1 year was treated as the gold standard and receiver operating characteristic (ROC) curve was used to analyze the effect of telomere length before transplantation or before donor mobilization in the judgement of the recurrence within 1 year after transplantation. The patients were stratified according to the optimal threshold value of telomere length for patients or donors, and Kaplan-Meier method was used to compare the progression-free survival (PFS) of patients with different stratification, and log-rank test was performed.Results:The median age of 33 patients was 34 years (14-61 years), and there were 17 males and 16 females; 31 patients were initially diagnosed with AML, 1 patient transferred from myelodysplastic syndrome (MDS) to AML, and 1 patient transferred from chronic granulocytic leukemia (CML) to AML; 14 received identical sibling transplantation and 19 received haploidentical sibling transplantation. The median age of the donors was 30 years (20-65 years), including 24 males and 9 females. Telomere length of bone marrow mononuclear cells before mobilization in 33 donors was longer than that in patients before transplantation (33 cases) and at +30 d after transplantation (31 cases) [(6.67±0.31) kb, (6.40±0.33) kb, (6.48±0.33) kb, respectively; all P < 0.05], and the difference between patients before and at +30 d after transplantation was not statistically significant ( t = 0.89, P = 0.378), and the telomere length of bone marrow mononuclear cells in 11 patients +180 d after transplantation was (6.66±0.18) kb. The incidence of acute graft-versus-host disease (aGVHD) after transplantation was 45.5% (15/33), the incidence of infection with clear imaging and pathogenic basis was 39.4% (13/33), the mortality rate within 1 year after transplantation was 3.0% (1/33), and the recurrence rate within 1 year after transplantation was 15.2% (5/33). There were no statistically significant differences in telomere length of donor pre-mobilization bone marrow mononuclear cells between the groups with and without aGVHD and between the infected and non-infected groups (all P > 0.05).Compared with patients who had not relapsed within 1 year after transplantation, telomere length of donor pre-mobilization bone marrow mononuclear cells was shorter in patients who relapsed within 1 year after transplantation [(6.39±0.19) kb vs. (6.72±0.30) kb, t = -3.23, P = 0.011], telomere length was longer in patients before transplantation [(6.75±0.16) kb vs. (6.35±0.36) kb, t = 4.17, P = 0.001]. ROC curve analysis showed that the optimal threshold values for telomere length of pre-transplantation and donor pre-mobilization bone marrow mononuclear cells were 6.48 and 6.42 kb, respectively for patients who relapsed within 1 year after transplantation. PFS in patients with pre-transplantation bone marrow mononuclear cells telomere length < 6.48 kb was better than that in patients with telomere length ≥ 6.48 kb ( P = 0.003); PFS in patients with pre-mobilization bone marrow mononuclear cells telomere length>6.42 kb was better than that in patients with telomere length ≤ 6.42 kb ( P < 0.001). Conclusions:In allo-HSCT for AML, patients have an increased risk of relapse within 1 year after transplantation when their pre-transplantation bone marrow mononuclear cells telomere length is long and the donor bone marrow mononuclear cells telomere length is short.

Technical points of human use experience of ethnic medicine / 中国中药杂志

Ethnic medicine has a rich history of application. Because of the large number of ethnic groups, wide geographical distribution, and unique medical systems in China, the research on the human use experience(HUE) of ethnic medicine should combine the characteristics of ethnic medicine, be based on practical experience, and respect folk practice and tradition. The clinical positioning of ethnic medicine should consider three factors, i.e., population region, dominant diseases, and clinical demand. We should consider the development of traditional preparations that meet the needs of ethnic regions and encourage the development of new drugs that can be popularized and used nationwide for the dominant diseases of ethnic medicines. Attention should be paid to the problems such as a large number of customary articles or substitutes of ethnic medicinal materials, the phenomena of foreign bodies with the same name and different names for the same substance, the different standards of medicinal materials, and the poor processing standards. The name, processing method, source, medicinal parts, and dosage of ethnic medicinal materials or decoction pieces should be determined, and resources should be carefully evaluated to ensure the safety of medicinal resources and ecology. The preparation of ethnic medicine is mostly in the form of pills, powder, ointment, etc., with simple processing technology. The problems of low-quality stan-dards of some preparations, different prescriptions with the same name, and inconsistent processing technology should be overcome, and the process route and main process parameters should be clarified to lay the foundation for the subsequent empirical research on HUE. In the collection and analysis of the HUE data of ethnic medicine, the core guiding ideology of "patient-centered" should be established, and the experience data of patients should be collected. The problems of weak links existing in the inheritance of ethnic medicine should be solved, and flexible and diverse methods should be adopted. Meanwhile, on the premise of complying with the requirements of the principles of medical ethics, we should respect the religion, culture, and customs of ethnic areas to obtain the key HUE information of ethnic medicine. On the basis of the patient preference information and differences in regional disease epidemiology, population characteristics, and medical practice, whether the HUE conclusions of ethnic medicine can be extrapolated to patients outside the region is evaluated from the aspects of clinical benefits, risk tolerance, risk acceptance, etc. The HUE research on ethnic medicine is carried out in a clear way to guide the research and development of new ethnic medicines.

The Dynamics of Dopamine D2 Receptor-Expressing Striatal Neurons and the Downstream Circuit Underlying L-Dopa-Induced Dyskinesia in Rats / 神经科学通报·英文版

L-dopa (l-3,4-dihydroxyphenylalanine)-induced dyskinesia (LID) is a debilitating complication of dopamine replacement therapy for Parkinson's disease. The potential contribution of striatal D2 receptor (D2R)-positive neurons and downstream circuits in the pathophysiology of LID remains unclear. In this study, we investigated the role of striatal D2R+ neurons and downstream globus pallidus externa (GPe) neurons in a rat model of LID. Intrastriatal administration of raclopride, a D2R antagonist, significantly inhibited dyskinetic behavior, while intrastriatal administration of pramipexole, a D2-like receptor agonist, yielded aggravation of dyskinesia in LID rats. Fiber photometry revealed the overinhibition of striatal D2R+ neurons and hyperactivity of downstream GPe neurons during the dyskinetic phase of LID rats. In contrast, the striatal D2R+ neurons showed intermittent synchronized overactivity in the decay phase of dyskinesia. Consistent with the above findings, optogenetic activation of striatal D2R+ neurons or their projections in the GPe was adequate to suppress most of the dyskinetic behaviors of LID rats. Our data demonstrate that the aberrant activity of striatal D2R+ neurons and downstream GPe neurons is a decisive mechanism mediating dyskinetic symptoms in LID rats.

Expression of SEC61G in Oral Squamous Cell Carcinoma and Its Prognostic Value / 肿瘤防治研究

Objective To analyze the expression of SEC61G in oral squamous cell carcinoma (OSCC) tissues and cell lines and determine its correlations with the clinicopathological features and prognosis of patients with OSCC. Methods The expression of SEC61G in OSCC tissues and its diagnostic and prognostic value were detected in the TCGA database. The expression levels of SEC61G in paraffin-embedded OSCC tissues and adjacent normal tissue specimens of 64 patients with OSCC were detected by immunohistochemistry. The correlation of SEC61G expression in OSCC tissues with the clinicopathological features was analyzed. Kaplan-Meier survival curve analysis showed that the expression of SEC61G correlated with the overall survival time of patients with OSCC. Cox regression analysis was used to analyze prognostic influence factors. Results The expression of SEC61G in OSCC tissues was significantly higher than that in para-carcinoma tissues (P < 0.05), consistent with the results of the TCGA database analysis, and its expression was closely related to N stage and clinical stage (P < 0.05). The overall survival of patients with OSCC in the group with low SEC61G expression was significantly higher than that in the high SEC61G expression group (P < 0.05). N stage and SEC61G expression were the prognostic influence factors for patients with OSCC (P < 0.05). SEC61G expression was an independent predictor of the prognosis of patients with OSCC (P < 0.05, AUC=0.923). Conclusion SEC61G is highly expressed in OSCC tissues and associated with N stage and clinical stage. Its high expression is associated with poor prognosis of patients. It may be a diagnostic biomarker for OSCC.

Spatiotemporal evolution of COVID-19 epidemic in the early phase in China / 中华流行病学杂志

Objective: Based on the geographic information systems, we exploreed the spatiotemporal clustering and the development and evolution of COVID-19 epidemic at prefectural level in China from the time when the epidemic was discovered to the time when the lockdown ended in Wuhan. Methods: The information and data of the confirmed COVID-19 cases from December 8, 2019 to April 8, 2020 were collected from 367 prefectures in China for a spatial autocorrelation analysis with software GeoDa, and software ArcGIS was used to visualize the results. Software SatScan was used for spatiotemporal scanning analysis to visualize the hot-spot areas of the epidemic. Results: The incidence of new cases of COVID-19 had obvious global autocorrelation and the partial autocorrelation results showed that incidence of COVID-19 had different spatial distribution at different times from December 8, 2019 to March 4, 2020. There was no significant difference in global autocorrelation coefficient from March 5, 2020 to April 8, 2020. The statistical analysis of spatiotemporal scanning identified two kinds of spatiotemporal clustering areas, the first class clustering areas included 10 prefectures, mainly distributed in Hubei, from January 13 to February 25, 2020. The secondary class clustering areas included 142 prefectures, mainly distributed in provinces in the north and east of Hubei, from January 23 to February 1, 2020. Conclusions: There was a clear spatiotemporal correlation in the distribution of the outbreaks in the early phase of COVID-19 epidemic (December 8, 2019-March 4, 2020) in China. With the decrease of the case and effective prevention and control measures, the epidemics had no longer significant correlations among areas from March 5 to April 8. The study results showed relationship with time points of start and adjustment of emergency response at different degree in provinces. Furthermore, improving the early detection of new outbreaks and taking timely and effective prevention and control measures played an important role in blocking the transmission.

Objective:To investigate the clinical features and treatment status of immune-related myositis (IRM) caused by immune checkpoint inhibitors (ICIs) in order to improve the diagnosis and treatment rate of the disease.Methods:Two cases of IRM combined with the diagnosis and treatment were described and the literature about IRM in the past 10 years was reviewed, and the clinical data of 59 patients were analyzed.Results:IRM was more common in males, with a total of 47 (79.7%). IRM usually occurred after 45 days of medication or after two doses. The clinical manifestations were mainly myalgia and muscle weakness, which were more common in the limbs. The initial symptoms were ptosis and diplopia. Fifty patients (84.7%) had serum creatine kinase (CK) levels higher than twice the upper limit of normal (UNL). In immunological examinations, 18 patients were found to be positive for anti-rhabdoid muscle antibody (AsM-Ab), while most of the myositisspecific antibodies (MSAs) and myositis-associated antibodies (MAAs) were negative. Thirty-four patients (75.6%) had abnormal EMG, and most patients showed myogenic injury. Muscle magnetic resonance imaging (MRI) showed muscle edema and inflammation in 8 patients. Muscle biopsies from 18 (45.0%) patients showed varying degrees of necrotic myofibers. Fifty-seven patients (96.6%) discontinued ICIs after developing IRM, 54(91.5%) received cortico-steroids, and 20(33.9%) received other treatments including intravenous immuno-globulin (IVIG), plasma exchange.Conclusion:IRM can occur in the early stage of ICIs treatment. Electro-myography, muscle MRI and muscle biopsy in suspicious cases can improve the diagnosis rate of the disease. Early use of corticoteroid, IVIG and other immunotherapy can effectively alleviate the disease.

Long non-coding RNA SPATA31D5P promoting proliferation, migration and invasion of breast cancer cells through adsorption of microRNA-320a / 解剖学报

Objective Long non-coding RNA(lncRNA) are aberrantly expressed in breast cancer(BC) and strongly associated with its survival prognosis. The aim of this study is to investigate the expression and effect of IncRNA SPATA31D5P on the invasion and migration capacity of breast cancer cells through adsorption of miR-320a. Methods Totally 30 cases of BC tissues and paraneoplastic tissues were collected, and the expression levels of SPATA31D5P in BC tissues and BC cell lines were detected by Real-time PCR. MDA-MB-231 cells were transfected with SPATA31D5P siRNA interference vector, and cell proliferation, invasion and migration capacity were determined using the cell counting kit-8 assay (CCK-8), 5-ethynyl-2'- deoxyuridine(EdU), Transwell and wound-healing assay respectively. And cell cycle and apoptosis were detected by flow cytometry. Bioinformatics approachs were used to screen for miRNAs that could bind complementarily to SPATA31D5P, and the regulatory effect of SPATA31D5P on miR-320a was detected by Real-time PCR and dual luciferase reporter assay. Results SPATA31D5P levels were significantly higher in BC tissues than in adjacent normal breast tissues, and SPATA31D5P expression was higher in each BC cell line than in normal breast epithelial cells MCF10 A. The level of SPATA31D5P in the interference group was 0. 288±0. 052, which was lower than that of the blank control group 1. 114±0. 096 and negative control (NC) group 1. 079±0. 128 (P< 0. 01). The proliferation activity of MDA- MB-231 cells in the interfered group was significantly reduced and apoptotic rate was obviously increased compared to the NC and control groups (P<0. 01) ;the Gj phase block was observed in the interfered group; the scratch healing rate and number of perforated cells in the interference group were (14. 36 ± 1. 75) % and (26±1.52), which were lower than (52. 25± 1.87)% and ( 67. 33 ± 2. 91 ) of the NC group (PcO.Ol). Dual luciferase experiments confirmed that SPATA31D5P could directly regulate miR-320a expression and luciferase activity. Conclusion SPATA31D5P is highly expressed in BC, interfering with SPATA31D5P expression effectively inhibits the proliferation, migration and invasion of MDA-MB-231 cells, and the mechanism may be related to the targeted regulation of miR-320a.

Mechanisms of saffron in treatment of depression based on network pharmacology / 中国药理学通报

Aim To explore the main pathways and possible mechanisms of saffron in treatment of depression using network pharmacology. Methods A network of active components of saffron-depression disease target was constructed through the TCM System Pharmacology Database (TCMSP), Genecards, Uniprot database, Cytoscape software, and ClueGo analysis tool, and GO biological process and KEGG pathway enrichment analysis were performed, and molecular docking verification was carried out using Autodock vina software. Results The five main chemical components quercetin, kaempferol, crocealdehyde, crocetin, and isorhamnetin may pass through the IL-17 signaling pathway, HIF-1 signaling pathway and Toll-like inflammatory pathways such as receptor signaling pathway, PI3K-Akt signaling pathway, MAPK signaling pathway, relaxin signaling pathway, Thl7 cell differentiation and other pathways, playing an antidepressant effect. In the PI3K-Akt signaling pathway and MAPK signaling pathway, the targets of saffron for depression were mainly enriched in multiple targets such as BD-NF, TNF, IL-1, IL-6, MAPK8, JUN, GSK3B, N0S3 and so on. The results of molecular docking verification indicated a good docking effect of saffron and crocetin with the BDNF target in the antidepressant pathway of saffron. Conclusions The mechanism of saffron treatment of depression is mainly reflected in the regulation of neurotrophic factors, anti-inflammatory, anti-oxida-tive stress, etc., providing a theoretical basis for clinical application.

Complications and management of penile augmentation with hyaluronic acid injection / 亚洲男科学杂志(英文版)

Hyaluronic acid injection is becoming a popular way for penile augmentation. However, only few studies and follow-ups have investigated the various complications of hyaluronic acid injection and their corresponding management. In this study, a total of 230 patients who had penile augmentation with hyaluronic acid injection from January 2018 to December 2019 were examined on follow-up for penile girth, complications, and their corresponding management. At 1-month, 3-month, and 6-month postoperative follow-ups, the penile circumference had increased by 2.66 ± 1.24 cm, 2.28 ± 1.02 cm, and 1.80 ± 0.83 cm, respectively. During the entire 6-month follow-up, 4.3% had complications such as subcutaneous bleeding, subcutaneous nodules, and infection. There were no systemic or local allergic reactions among all the patients. All complications were treated accordingly, and no further deterioration or severe sequelae were observed. Although complications of hyaluronic acid injections are mild and rare, these may affect the patient's satisfaction postoperatively. Preoperative redundant prepuce may increase the incidence of penile edema or postoperative gel migration. Standardization of the surgery protocol and elucidation of the effects of other injection parameters are still lacking. Nevertheless, it still highlights the importance of preoperative preparation and surgical technique.

Analysis of clinical research outcome indicators of traditional Chinese medicine in treatment of diabetic foot / 中国中药杂志

To analyze the outcome indicators from the randomized controlled trials(RCTs) on traditional Chinese medicine(TCM) treatment for diabetic foot, and to lay a foundation for the establishment of the core index set of the clinical trials on TCM treatment of diabetic foot. Computer retrieval of RCTs on TCM treatment of diabetic foot was performed in CNKI, Wanfang, SinoMed, PubMed, Cochrane Library, EMbase and Web of Science databases. Literature screening and data extraction were conducted independently by two researchers in strict accordance with inclusion and exclusion criteria. Any difference was resolved through discussion. A total of 72 RCTs involving 5 791 patients were included and 204 indicators were used. The number of indicators used in a single study was 2-22, with an average of 3 indicators used for each RCT. The indicators with top 16 frequency were clinical total effective rate, ankle brachial index(ABI), ulcer area, TCM syndrome integral, fibrinogen(FIB), fasting blood glucose(FBG), plasma viscosity(PV), c-reactive protein(CRP), saccharification blood of eggs(HbAlc), 2 h postprandial blood glucose(2 hPG), wound healing time, triglyce-rides(TC), TCM efficacy for syndromes, total cholesterol(TG), percutaneous oxygen partial pressure(TCPO2) and TCM symptom scores. The difference in selection of RCT indicators was large among TCM treatment methods for diabetic foot, and the combination of outcome indicators was arbitrary. The description on indexes was not standardized. Some non-laboratory examination indicators, some indicators not recommended in guidelines or not recognized in clinical practice, and some self-made indicators were not explained in detail. There was a lack of standardized evaluation criteria for indicators. The indicators had large time-point difference in measurement, and the time points were not distinguished in the measurement for diabetic foot patients with different degrees of severity. In addition, the patients with long course of treatment weren't timely measured. The characteristics of TCM or significant endpoint indicators were insufficient. It was urgent to establish the core index set of TCM in treating diabetic foot.

Chronic sleep deprivation exacerbates cognitive and pathological impairments in APP/PS1/tau triple transgenic Alzheimer's disease model mice / 生理学报

Sleep exerts important functions in the regulation of cognition and emotion. Recent studies have found that sleep disorder is one of the important risk factors for Alzheimer's disease (AD), but the effects of chronic sleep deprivation on the cognitive functions of AD model mice and its possible mechanism are still unclear. In the present study, 8-month-old male APP/PS1/tau triple transgenic AD model (3xTg-AD) mice and wild type (WT) mice (n = 8 for each group) were subjected to chronic sleep deprivation by using the modified multiple platform method, with 20 h of sleep deprivation each day for 21 days. Then, open field test, elevated plus maze test, sugar water preference test, object recognition test, Y maze test and conditioned fear memory test were performed to evaluate anxiety- and depression-like behaviors, and multiple cognitive functions. In addition, the immunohistochemistry technique was used to observe pathological characteristics in the hippocampus of mice. The results showed that: (1) Chronic sleep deprivation did not affect anxiety- (P = 0.539) and depression-like behaviors (P = 0.874) in 3xTg-AD mice; (2) Chronic sleep deprivation exacerbated the impairments of object recognition memory (P < 0.001), working memory (P = 0.002) and the conditioned fear memory (P = 0.039) in 3xTg-AD mice; (3) Chronic sleep deprivation increased amyloid β (Aβ) deposition (P < 0.001) and microglial activation (P < 0.001) in the hippocampus of 3xTg-AD mice, without inducing abnormal tau phosphorylation and neurofibrillary tangles. These results indicate that chronic sleep deprivation exacerbates the impairments of recognition memory, working memory and conditioned fear memory in 3xTg-AD mice by aggravating Aβ deposition and the excessive activation of microglia in the hippocampus.

Application of real world study and human use experience in research and development of new traditional Chinese medicine drugs / 中国中药杂志

Real world study(RWS) refers to the process of collecting real world data related to the health of research subjects in the real world environment for pre-set clinical problems and obtaining the status of drug use and potential benefits/risks through analysis. The data are derived from the hospital information system(HIS), medical insurance system, disease registration system, adverse drug reaction monitoring system, etc. Human use experience of traditional Chinese medicine(TCM) is a new concept put forward by experts after summarizing the problems existing in clinical trials of new TCM drugs. The data come partially from the real world, and more importantly, such key elements as the formulated prescriptions of new TCM drugs, principles and methods, and clinical applications should be covered. RWS is mainly used for adverse drug reaction monitoring after marketing, benefit evaluation of listed drugs, decision-making of medical treatment and medical insurance, as well as supervision and approval of special medical devices and special drugs. It is complementary to randomized controlled clinical trials. Human use experience is suitable for the research and development of Chinese medicinal compound preparations and the expansion of functions and indications. There are no special provisions for clinical indications and target population. There exists a sequential relationship between the human use experience and clinical trials. Specifi-cally, the summarization of human use experience provides good support for the design and implementation of clinical trials, which is an important segment in the research and development of new TCM drugs. The correlation between real-world data and research results and their reliability should be ensured in RWS, and the unreality should be avoided. The key to summarizing the human use experience is to identify the clinical orientation, target population, course of treatment, usage and dosage of new TCM drugs, and it should be noted that human use experience does not only mean clinical experience. Experimental clinical trial(PCT), a type of study in the real world, has been commonly employed for the summary of human use experience. RWS and human use experience are different research designs targeting different clinical questions in the research and development of new TCM drugs, which can be flexibly selected depending on the actual situation.
