ObjectiveTo explore the relationship between the kidney deficiency and governor vessel cold syndrome and the kidney deficiency damp-heat syndrome in ankylosing spondylitis （AS） patients and the five evolutive phases and six climatic factors of their birth and onset year based on the theory of five movements and six climates （FMSC）. MethodsTotally 1791 patients with AS who were admitted to China-Japan Friendship Hospital from September 2010 to September 2020 and met the diagnostic and inclusion criteria were selected in this study. The clinical data were classified into two types of syndromes， kidney deficiency and governor vessel cold syndrome and the kidney deficiency damp-heat syndrome based on the diagnostic criteria of traditional Chinese medicine syndromes. The date of birth and the year of disease onset were converted into FMSC symbols according to the perpetual almanac （《万年历》）， and the two could be converted into the terrestrial branch， year evolutive phase， host evolutive phase， guest evolutive phase， host climatic qi， guest climatic qi， celestial manager qi， guest climatic qi adding to fixed host qi， combined analysis of five evolutive phases and six climatic factors， solar terms， and season of the date of birth， as well as the terrestrial branch， year evolutive phase， and celestial manager qi of the year of disease onset. Univariate analyses were performed using the two independent samples t-test or the Mann Whitney U-test， the Pearson （Pearson） χ2 test， or one-way logistic regression analyses， and variables for which statistical significance existed in the one-way analyses were included in the multivariate logistic regression analyses. General conditions， clinical manifestations， physical signs， laboratory indicators ［including C reactive protein （CRP）， erythrocyte sedimentation rate （ESR）， and humans leukocyte antigen B27 （HLA-B27）］， measurement （including occipital wall distance， jaw peduncle distance， finger-to-ground distance， thoracic range of motion， and Schober experiment）， and distribution of FMSC of birth and disease onset between AS patients with kidney deficiency and governor vessel cold syndrome and with the kidney deficiency damp-heat syndrome were compared， and the association between FMSC and AS patients with kidney deficiency and governor vessel cold syndrome and the kidney deficiency damp-heat syndrome was studied. ResultsThe differences in ESR， CRP， chest mobility， occurrence of achilles tendon enthesitis， and peripheral arthritis between the two groups of patients were statistically significant （P＜0.05）. Single factor analysis found that taking kidney deficiency and governor vessel cold syndrome as control the following FMSC factors increases the risk of developing kidney deficiency damp-heat syndrome： excess of water in year evolutive phase at birth， excess of wood in host evolutive phase at birth， excess of wood in guest evolutive phase at birth， excess of wood in year evolutive phase of onset， deficiency of metal in year evolutive phase at birth （OR = 2.000， P = 0.004）， excess of metal in host evolutive phase at birth （OR = 1.745， P = 0.024） or excess of wood （OR = 1.781， P = 0.023）， deficiency of fire in guest evolutive phase at birth （OR = 1.689， P = 0.049） or deficiency of wood （OR = 1.901， P = 0.018） or excess of metal （OR = 2.163， P = 0.004）， excess of water in year evolutive phase at the disease onset （OR = 1.880 ， P = 0.013） or deficiency of wood （OR = 1.707， P = 0.022）. Multivariate logistic regression analysis found that the risk of developing kidney deficiency damp-heat syndrome in AS was increased by deficiency of metal in year evolutive phase at birth， excess of metal in host evolutive phase at birth， higher level of ESR， greater the chest mobility， incidence of concomitant Achilles tendon enthesitis and peripheral arthritis. ConclusionThe year evolutive phase and host evolutive phase at birth play a significant role in the development of kidney deficiency and governor vessel cold syndrome AS. Risk of developing kidney deficiency damp-heat syndrome can be increased by excess of water or deficiency of metal in year evolutive phase at birth， and excess of wood or excess of metal in host evolutive phase at birth and the kidney deficiency damp-heat syndrome in ankylosing spondylitis.

Experience in Application of the Lotus Medicinal Herbs for Female Reproductive System Diseases / 中医杂志

As one of notable works of HUANG Yuanyu， a renowned physician from the Qing Dynasty， The Indications of Classics by Four Medical Sage emphasize the theoretical paradigm of “one qi circulation” with a particular focus on the middle qi. Building upon disease differentiation and treatment， HUANG Yuanyu attaches great importance to understanding the underlying cause of the disease. It is believed that the imbalance of the six climatic factors is the fundamental cause of diseases. The concept of mutual interaction between the physiological and pathological aspects of the six climatic factors is proposed to grasp the basic pathogenesis. Based on the individual's specific condition of six climatic factors， excess or deficiency， specific prescriptions are formulated. The diagnosis and treatment system can be summarized as a “differentiation of diseases → disease etiology → differentiation of the condition of six climatic factors → individualized pathogenesis of traditional Chinese medicine （TCM） → prescription of TCM” model based on the holistic view. HUANG Yuanyu' s diagnosis and treatment system is highly practical and can provide reference for clinical diagnosis and treatment of diseases in TCM.

Development and application of three-dimensional point cloud radiotherapy real-time monitoring system based on depth camera / 中华放射肿瘤学杂志

Objective:To develop the real-time radiotherapy monitoring system of three-dimensional (3D) point cloud by using depth camera and verify its feasibility.Methods:Taking the depth camera coordinate system as the world coordinate system, the conversion relationship between the simulation CT coordinate system and the world coordinate system was obtained from the calibration module. The patient's simulation CT point cloud was transformed into the world coordinate system through the above relationship, and registered with the patient's surface point cloud obtained in real-time manner by the depth camera to calculate the six-dimensional (6D) error, and complete the positioning verification and fractional internal position error monitoring in radiotherapy. Mean and standard deviation of 6D calculation error, Hausdorff distance of point cloud after registration and the running time of each part of the program were calculated to verify the feasibility of the system. Fifteen real patients were selected to calculate the 6D error between the system and cone beam CT (CBCT).Results:In the phantom experiment, the errors of the system in the x, y and z axes were (1.292±0.880)mm, (1.963±1.115)mm, (1.496±1.045)mm, respectively, and the errors in the rotation, pitch and roll directions were 0.201°±0.181°, 0.286°±0.326°, 0.181°±0.192°, respectively. For real patients, the translational error of the system was within 2.6 mm, the rotational error was approximately 1°, and the program run at 1-2 frames/s. The precision and speed met the radiotherapy requirement. Conclusion:The 3D point cloud radiotherapy real-time monitoring system based on depth camera can automatically complete the positioning verification before radiotherapy, real-time monitoring of body position during radiotherapy, and provide error visual feedback, which has potential clinical application value.

Changes of peripheral perfusion index in very low birth weight infants with late-onset sepsis / 中国小儿急救医学

Objective:To analyze the changes of peripheral perfusion index (PPI) with late-onset sepsis (LOS) in very low birth weight infants during hospitalization.Methods:Very low birth weight infants admitted to the neonatal intensive care unit of Children′s Hospital of Fudan University from August 1, 2021 to August 31, 2022 were consecutively included.Infants with admission age ≥three days and unstable circulation, or positive blood culture within three days after birth were excluded.From the day of admission, the PPI values of the right hand and either foot of the infants were measured with Masimo SET Radical-7 everyday while whether LOS occurred during hospitalization was observed.The mean PPI curve of very and extremely low birth weight infants without LOS was plotted.For those with LOS confirmed by blood culture, the PPI change trajectory three days before and after the occurrence of LOS was drawn, and the change trend of PPI before the occurrence of LOS was analyzed by trend chi-square test.Non-parametric test was used to analyze the effect of LOS on pre- and post-ductal PPI values.Results:A total of 107 very low birth weight infants were included in the final analysis.Among them, there were 11 infants confirmed as LOS by blood culture, 37 infants diagnosed as clinical LOS, and 59 infants without LOS.Pre-and post-ductal PPI values of very low birth weight infants without LOS were 2.06±1.30 and 1.72±0.92, respectively; those with clinical LOS were 1.90±0.94 and 1.58±0.83, respectively; those with LOS confirmed by blood culture were 1.92±1.11 and 1.62±0.82, respectively.For infants with LOS confirmed by blood culture, the pre-and post-ductal PPI values showed a continuous downward trend during three days before the onset of disease, with the lowest PPI values on the first day before the diagnosis of blood culture.The downtrend of pre-ductal PPI was statistically significant ( χtrend2=5.57, P<0.05). Conclusion:The PPI value of very low birth weight infants show a downward trend when LOS occurs.It should be observed dynamically in clinical practice, which is helpful to suspect or identify LOS as early as possible.

A monitoring aid for movement disorder rehabilitation / 国际生物医学工程杂志

Objective:To design a motor impairment rehabilitation monitoring aid for the assessment of motor impairment in patients who do not have or have difficulty walking independently.Methods:An assistive device vehicle was designed, equipped with an accelerometer and a six-dimensional force sensor. The normal walking (NW) group and abnormal walking group were set up, in which the abnormal walking group included moderate abnormal walking (MA) group, moderate abnormal walking with the aid of the assistive vehicle (MA-V) group, severe abnormal walking (SA) group, and severe abnormal walking with the aid of the assistive vehicle (SA-V) group. In the MA-V group, the range of knee movement was adjusted from 0 to 30°, and in the SA group, the knee joint was completely unbending. The gait cycles, peak and mean acceleration values of the right and left legs were evaluated by accelerometers, and changes in the upper limb forces were assessed by six-dimensional force transducers.Results:For the moderate impairment group, the difference in gait cycle between the MA and MA-V groups was not statistically significant ( P>0.05), and the gait cycle in the MA-V group was slightly greater than that in the MA group. For the severe injury group, the gait cycle of the SA-V group was lower than that of the SA group, and the difference was statistically significant ( P<0.01). For all abnormal groups, the mean and peak acceleration of the left leg were greater than that of the right leg, and the difference between the peak acceleration of the left leg and that of the right leg was statistically significant ( P<0.05). In the abnormal walking pattern, the mean (absolute) value of the left hand force was greater than that of the right hand, especially in the Z-axis. The standard deviations of the combined forces on the left side for the NW, MA-V, and SA-V groups were 2.759, 8.297, and 13.118 N, respectively. The SA-V group had the highest dispersion in the force scatter plot, while the NW group had a better concentration. Conclusions:An assistive vehicle equipped with an accelerometer and a six-dimensional force sensor was designed to help physicians in the assessment and rehabilitation of motor disorders.

Hsa_circ_0000670 promoted the progression of gastric cancer through the miR-515-5p/SIX1 molecular axis / 中华肿瘤杂志

Objective: To explore whether hsa_circ_0000670 promotes the progression of gastric cancer by regulating the miR-515-5p/SIX1 molecular axis. Methods: The gastric cancer and adjacent normal tissues of 35 gastric cancer patients admitted to Rugao Hospital Affiliated to Nantong University from 2014 to 2015 were collected. The expression levels of circ_0000670, miR-515-5p and Sine oculis homeobox 1 (SIX1) in gastric cancer tissues and cells were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. The correlations between circ_0000670 and miR-515-5p, miR-515-5p and SIX1, circ_0000670 and SIX1 were analyzed by the Pearson method. Patients were divided into low circ_0000670 expression group (17 cases) and high circ_0000670 expression group (18 cases) based on the median of circ_0000670 expression level, and Kaplan-Meier was used to analyze the 5-year survival of patients. Cell proliferation was assessed via clone formation assay. Cell cycle and apoptosis were detected by flow cytometry. Wound healing and Transwell assays were used to detect cell migration and invasion ability. The targeting relationship between miR-515-5p and circ_0000670 or SIX1 was confirmed by the dual luciferase reporter assay. Nude mice were injected into HGC-27 cells transfected with sh-NC or sh-circ_0000670, and the volume and weight of the transplanted tumor were measured, also, the levels of circ_0000670, miR-515-5p and SIX1 in the transplanted tumor tissue were detected. Results: The expression levels of circ_0000670 and SIX1 in gastric cancer tissues and cell lines were significantly increased (P<0.05), while the expression levels of miR-515-5p were significantly decreased (P<0.05). The survival rate of patients in the low circ_0000670 expression group (82.4%) was significantly higher than that in the high circ_0000670 expression group (28.7%, P=0.034). Circ_0000670 was negatively correlated with miR-515-5p (r=-0.846, P<0.001), and miR-515-5p was negatively correlated with SIX1 (r=-0.615, P<0.001), but circ_0000670 was positively correlated with SIX1 (r=0.814, P<0.001). Transfection of si-circ_0000670 or miR-515-5p mimic could significantly reduce the number of clone-forming cells, migration distance, migration and invasion cells (P<0.05), and increase the ratio of G(0)/G(1) phase cells, apoptosis rate and the protein level of E-cadherin (P<0.05), decreased the proportion of S-phase cells and the protein level of Vimentin (P<0.05). The dual luciferase report assay confirmed that circ_0000670 could target miR-515-5p, and miR-515-5p could bind to SIX1. Co-transfection of si-circ_0000670 and miR-515-5p inhibitor could significantly attenuate the effects of si-circ_0000670 on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Co-transfection of miR-515-5p mimic and pcDNA-SIX1 could significantly reduce the effects of miR-515-5p mimic on cell proliferation, migration, invasion, cell cycle and apoptosis (P<0.05). Compared with the sh-NC group [volume=(596.20±125.46) mm(3) and weight=(538.00±114.39) g], the volume and weight of transplanted tumors in the sh-circ_0000670 group [volume=(299.20±47.58) mm 3 and weight=(289.80±48.73 g)] were significantly reduced (P<0.05), the expression levels of circ_0000670 and SIX1 were significantly reduced (P<0.05), and the expression level of miR-515-5p was significantly increased (P<0.05). Conclusion: Knockdown of circ_0000670 could inhibit cell proliferation, migration, invasion of gastric cancer cells, induce cell cycle arrest in G(0)/G(1) phase and promote cell apoptosis by regulating the miR-515-5p/SIX1 axis.

Resumen Introducción: Hay información escasa sobre la evolución de los enfermos hospitalizados por neumonía por COVID-19 a mediano plazo. El objetivo de este estudio fue determinar en pacientes con neumonía moderada (NM) o grave (NG) por COVID-19, el impacto clínico, funcional respiratorio y tomográfico a los 6 meses. Métodos: Se realizó análisis según grupos de NM y NG, desaturadores (PD) en la prueba de cami nata de 6 minutos y presencia del patrón tomográfico de alta resolución (TACAR) símil fibrótico. Se compararon los resultados a los 3 y 6 meses. Resultados: Se incluyeron 129 pacientes, edad 57±11 años, comorbilidades frecuentes (hipertensión arterial 38.1%, diabetes 30.4% y respiratorias 18.6%). Al comparar 3 y 6 meses se ob servó mejoría de la calidad de vida en NM y NG. Los PD presentaron menor metraje caminado, peor calidad de vida y mayor presencia de patrón símil fibrótico. Este patrón se relacionó con la caída de la FVC 80% en NM y NG (p = 0.048 y p = 0.007), y con PD (p = 0.002). En el análisis multivariado, el patrón símil fibrótico s e asoció a la reducción de la CVF con OR = 4.44 (1.94-10.18, p<0.01) y a la desaturación, OR = 5.01 (1.63-15.42, p<0.01). En esta cohorte se observó mayor compromiso funcional y tomográfico en los PD. El patrón símil fibrótico se relacionó con peor evolución funcional y oximétrica. Discusión: Es importante el seguimiento de los pacientes con NG, los PD y los que presentan patrón fibrótico al alta de neumonía por COVID-19.

Abstract Introduction: There is scarce information about middle-term evolution of hospitalized patients who suffer from pneumonia caused by COVID-19. The objective of this study is to determine the clinical, respiratory, tomographic and functional impact on COVID-19 patients with moderate (MP) to severe (SP) pneumonia after six months of acute infection. Methods: Analysis was carried out by MP and SP groups, desaturators during the 6-minute-walking test and the presence of fibrotic like pattern on HRCT. Outcomes at 3 and 6 months were compared. Results: The analysis included 129 patients, between 57 ± 11 years old. Frequent comorbidities were: arterial hypertension 38.1%, diabetes 30.4%, respiratory 18.6%). Comparing 3 and 6 months, improvement in quality of life was observed in MP and SP. The DP walked less meters in the MWT, worsened life quality and more fibrotic like pattern. The fibrotic pattern was related to the fall of CVF < 80% on MP and SP (p = 0.048 and p = 0.007), and with DP (p = 0.002). On multivariated analysis, the fibrotic like pattern was associated to the reduction of CVF with OR = 4.44 (1.94-10.18, p<0.01) and desaturation OR = 5.01(1.63-15.42, p < 0.01). On this cohort it was observed more functional and tomographic compromise on the DP The fibrotic like pattern was related to worse functional evolution and oximetry. Discussion: Follow-up after discharge of COVID-19 patients with SP, DP or fibrotic changes in HCRT is underlined.

Significance of Siddha Thirithoda Balancing Food Stuffs

The Siddha system of medicine is an ancient medical system, which provides ‘Holistic Health’. The word ‘Siddha’ originated from the word ‘Siddhi’ meaning achievement of perfection, eternal bliss and accomplishment. The Siddha system evolved based on ninety-six tools (96 Thattuvam) which include physical, physiological, psychological and intellectual aspects of every human being. Among the 96 tools, the five elements i.e. Pancha bootham namely Earth, Water, Fire, Air and Space are the fundamental units of everything in the human body and the cosmos. There are three vital life factors (Vaatham, Pittam, Kabham) responsible for good health. There is a relationship between these to maintain the body’s healthy. Any increase or decrease in humour causes diseases. Thirthoda sama porutkal (TSP) maintains these humour when we are using our regular diet. This article details the TSP to maintain the body healthy.

ABSTRACT Background: Pulmonary hypertension (PH) comprises a heterogeneous group of diseases resulting in disability and increased morbidity and mortality. Cardiopulmonary rehabilitation (CR) is a therapeutic resource not widely used in this condition. Objective: The aim of this study was to evaluate the effects of a CR program on a walking test and on the quality of life in patients with group 1 and group 4 PH Methods: Patients were evaluated before and after the intervention with the six-minute walk test (6MWT) and Saint George's Respiratory Questionnaire (SGRQ). The program consisted of 8 weeks of supervised exercises within the institution. Results: Nineteen patients with precapillary PH diagnosed by right heart catheterization were included; 18 were women (94.7%) with a mean age of 45.5±14.3 years. Thirteen (68.4%) patients had group 1 PH and 6 (31.6%) had group 4 PH. There were statistically significant changes in the 6MWT [mean difference (MD) 31±27.3 m; p<0.001], and in the SGRQ (MD 8.2±10.2; p<0.01). No adverse events were reported during the program. Conclusions: Our study suggests that a supervised CR program in patients with PH could improve the distance walked and the quality of life.

Quantification of Pre-analytical Quality Indicators in a Clinical Laboratory and Formulating the Lean Six Sigma DMAIC Strategy

Introduction : Quality control of the laboratory has gained increased importance in the present years. 70 % of the errors in the clinical laboratory occur in the pre-analytical phase. With various guidelines to gauge the quality of the laboratory, Six Sigma Metrics remains by far the most difficult benchmark that a laboratory can achieve. We aimed to quantify the performance of the quality indicators of the routine clinical Biochemistry laboratory in the pre-analytical phase in the form of sigma metrics and devise measures and identify steps to decrease the percentage of errors by defining the DMAIC approach. Materials and Methods : One year retrospective data was collected from January, 2020 to December, 2020 from the data entry register and pre-analytical variables were quantified. Defects Per Million and sigma metric were calculated for each pre-analytical indicator. DMAIC approach was applied and post intervention sigma scores for the month of Jananuary, 2021, February, 2021 and March, 2021 were calculated. Results : Postinterventional analysis was done on a month-to-month basis to monitor the trend and also to ensure corrective action can be taken without delay. Out of 5 quality indicators which were quantified, the pre versus post sigma scores (March’21) are as follows: missing location of the patient (Sigma 4 versus 3.6), missing registration number (Sigma 3.7 versus 4.3) and both registration number and location missing (Sigma 3.6 versus 4.0), Homolysed sample (4.2 versus 4.6), insufficient sample volume (sigma 3.9 versus 4.7). Encouraging results in the form of improved Sigma scores were seen in four of the quality indicators except for the fact that the patient location were still missing in the forms and hence warrants continuous monitoring.

The application of sigma metrics in the laboratory to assess quality control processes in South Africa

Objective: This study aimed to determine the sigma metrics of analytes when using different total allowable error guidelines.Methods: A retrospective analysis was performed on 19 general chemistry analytes at Charlotte Maxeke Johannesburg Academic Hospital in South Africa between January 2017 and December 2017. Sigma metrics were calculated on two identical analysers, using internal quality control data and total allowable error guidelines from the Ricos biological variation database and three alternative sources (the Royal College of Pathologists of Australasia, the Clinical Laboratory Improvements Amendment, and the European Federation of Clinical Chemistry and Laboratory Medicine). Results: The sigma performance was similar on both analysers but varied based on the guideline used, with the Clinical Laboratory Improvements Amendment guidelines resulting in the best sigma metrics (53% of analytes on one analyser and 46% on the other had acceptable sigma metrics) and the Royal College of Pathologists of Australia guidelines being the most stringent (21% and 23%). Sodium and chloride performed poorly across all guidelines (sigma < 3). There were also month-to-month variations that may result in acceptable sigma despite poor performance during certain months.Conclusion: The sigma varies greatly depending on the total allowable error, but could be a valuable tool to save time and decrease costs in high-volume laboratories. Sigma metrics calculations need to be standardised

Application of 6-minute walk and grip strength tests in nursing evaluation of early arterial stiffness in community-dwelling elderly / 中国实用护理杂志

Objective:To explore the application of 6MWT and handgrip strength test in the nursing evaluation of arterial stiffness in community-dwelling elderly.Methods:From September 2019 to January 2020, 129 community-dwelling elderly people (age 60 years or older) were selected as the research subjects. Arterial stiffness was detected by pulse wave detector, and handgrip strength test and 6MWT were performed. Pearson correlation analysis and multiple linear regression methods were used to analyze the relationship between handgrip strength and 6MWT test indicators and aortic pulse wave velocity (aPWV) and augmentation index75 (AIx75).Results:The community-dwelling older people of aPWV was (10.50 ± 1.36) m/s and was negatively correlated with 6MWT distance and 6WMT work, of which the correlation coefficients were -0.404 and -0.285 respectively ( P<0.05). The community-dwelling older people of AIx75 was (28.51 ± 10.81) % and was negatively correlated with handgrip strength, relative grip strength, 6MWT distance and 6MWT work, of which the range of correlation coefficients were from -0.261 to -0.226 ( P<0.05). After adjusting for age, gender, and blood pressure, 6MWT distance and grip strength were independently related to aPWV and AIx75, respectively. Conclusions:In community-dwelling elderly people, both the grip strength test and 6MWT can be used for nursing evaluation of early arterial stiffness, but the specific evaluation role is different.

Design of internal quality control program for specific protein testing based on patient risk / 中华检验医学杂志

Objective:Patient risk-based statistical quality control (SQC) program was designed for 9 specific protein projects using Westgard sigma rules with run length.Methods:The cumulative coefficient of variation of immunoglobulin (Ig)G, IgA, IgM, C3, C4, rheumatoid factor (RF), antistreptolysin O (ASO), transferrin (TRF) and prealbumin (PA) from the laboratory department of Beijing Tongren Hospital between December 2018 to May 2019 were used as the estimated value of imprecision. The mean of the absolute value of the percentage difference of 10 batches in the laboratory, which was derived from the results of participating the external quality assessment (EQA), was used as the estimated value of bias. The National Center for Clinical Laboratories EQA evaluation criteria was used as an allowable total error (TEa), and the sigma value of each project (σ) was calculated. Westgard Sigma rule with run length was used to design appropriate SQC program for each project, including quality control rules, number of control measurements (N) and frequency of quality control.Results:The sigma value was larger than 6 for SQC procedure of IgG, IgA, IgM, C4 and TRF. SQC could be established with the use of 1 3s rule, number of control measurements (N)=2, number of runs (R)=1, and a run length of 1 000 patient samples. Combined with the average daily workload, internal quality control could be conducted once every 10 days for IgG, IgA, IgM and C4, every 50 days for TRF. The σ was 5.86 for C3, SQC program could be established with run length of 450 using 1 3S/2 2S/R 4s rule (N=2, R=1), combined with average daily workload, internal quality control could be conducted every 4.5 days. σ was between 3 and 4 for RF, ASO and PA. With the use of 1 3S/2 2S/R 4s/4 1s/6 X rule (N=6, R=1), SQC program with a run length of 45 and higher frequency internal quality control activities. Conclusion:It is feasible to use Westgard sigma rules with run length for the laboratories design of personalized risk-based SQC procedures, the method is very simple and intuitive. This tool is valued to be recommended to be actively applied by all clinical laboratories.

Evaluation of sacral neuromodulation system with new six-contact points electrode for the treatment of bladder dysfunction / 中华泌尿外科杂志

Objective:To investigate the effects of sacral neuromodulation (SNM)using the new six-contact electrode vs. the four-contact electrode in patients with refractory overactive bladder.Methods:The clinical data of 29 patients underwent SNM testing therapy from January 2018 to January 2020 in China Rehabilitation Research Center were reviewed. In six-contact points electrode group 16 patients accepted SNM with new six-contact points electrode, while 13 patients in four-contact points electrode group accepted SNM with four-contact points electrode. There were no significant differences between the two group in age [(51.63±4.67) vs. (51.85±7.18) years], gender (male/female, 4/12 and 5/8), urination frequency [(22.10±9.05) vs. (21.79±8.05) times/24h], mean voided volume [(135.68±56.98) vs. (131.00±53.05) ml], and urgency score [(2.78±0.97) vs. (3.02±0.91)] (all P>0.05). The number of sensitive contact points, the ratio of reaction contact points, operation time of stage I and the success rate of two groups were calculated. Results:The mean number of sensitive points of six-contact points electrode group (3.31± 0.95) was significantly higher than that of the four-contact points electrode group (1.85± 0.38), ( P<0.05). There was no significant difference in the ratio of reaction contact points [ (96.87±6.71)% vs. (96.15± 9.39)%] and operation time of stage I [(71.25± 18.21)min vs.(68.85± 10.83)min]between six-contact points electrode group and four-contact points electrode group ( P<0.05). The contact E4 and E5 of six-contact electrodes had similar reaction voltage ( P>0.05). The implant rate of six-contact points electrode group was (14/16, 87.5%), which was higher than that of four-contact points electrode group (10/13, 76.9%), but there was no statistical difference ( P>0.05). Conclusions:This study showed that six-contact electrodes has more sensitive points compared with four-contact electrodes. Application of six contact electrodes, patients might get a higher implant rate.

Exploration and practice of standardized residency training: a six-step approach based public curriculum design of clinical postdoctoral program / 中华医学教育探索杂志

The competency-based medical education has formed a global trend, and puts forward a greater challenge for educational design of resident training. The traditional curriculum cannot meet the goal of competency-based education as the curriculum design is lack of theoretical support. Curriculum design is the core of training content, and serves as a significant contributing factor of training outcome. Based on the six-step approach curriculum design, the theory and practice are integrated to form a curriculum design based on theoretical guidance. Through feedback evaluation, the current curriculum design is continuously improved in order to achieve a higher competency-based training quality. With the 5-year experiences and practice, preliminary reform demonstrates effectiveness. The current study hopes to share the teaching reform experiences of residency training base and provide references for colleagues of medical education.

Probe the syndrome differentiation system of six meridians of circular motion / 国际中医中药杂志

The internal organs and meridians were associated with Yin and Yang, five elements, six qi, and time and space, based on the holistic view of heaven, earth and human, according to Huangdi Neijing. The syndrome differentiation system of six meridians and Zang Fu meridians were established by Shanghan Zabing Lun, on the basis of the three Yin, three Yang, six meridians, and five Zang system in Huangdi Neijing. We put forward the concept of the six meridians syndrome differentiation system of circular motion, considering that the six meridians syndrome differentiation system actually implies the theory of circular motion. The syndrome differentiation system was constructed with the circular model of one qi circulating around the road, rising left and falling right, corresponding up and down, and maintaining conservation in the middle as the core, integrating Yin and Yang, five elements, six qi, Zang Fu and meridians, qi, blood and body fluid, and the integration of heaven, earth and human, focusing on "disease location and disease nature", taking classical prescriptions as the main treatments, and cooperating with external treatments such as acupuncture and moxibustion. We organically combined the circular motion with the syndrome differentiation of the six meridians, systematically interpreted the physiological bases, pathological changes, progressive patterns, and the treatments, based on syndrome differentiation, by inheriting the classical thinking mode of Hetu, Luoshu,Zhouyi, Huangdi Neijing, ShennongHerbal Classic, and Shanghan Zabing Lun.
