Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Aim To explore the effect and mechanism of the artesunate(ART)on hepatocellular carcinoma(HCC).Methods The cell lines MHCC-97H and HCC-LM3 were used to be detected.MTT and clone formation were used to determine the cell proliferation;Wound healing was used to detect the cell migration;Transwell was used to test the cell invasion.Flow-cy-tometry was used to detect cell apoptosis and cell cy-cle.RNA-seq and qRT-PCR was used to detect the genes expression.Results The proliferation,migra-tion and invasion of treated cells were obviously inhibi-ted(P＜0.01).Moreover,the apoptosis rate in-creased significantly,so did the proportion of G2/M cells.Transcriptomic analysis identified GADD45A as a potential target of ART through RNA-sequencing da-ta,and suggested that ART might induce apoptosis and cell cycle arrest through regulating the expression of GADD45A.In addition,the results of mechanism studies and signaling analysis suggested that GADD45A had interaction with its upstream gene NACC1(nucle-us accumbens associated 1).Moreover,after ART treatment,the expressions of GADD45A and NACC1 were changed significantly.Conclusion ART may be a potential drug to resist HCC by affecting the expres-sion of GADD45A and its upstream gene NACC1,which provides a new drug,a new direction and a new method for the clinical treatment of HCC.

Objective To investigate the clinical effect of limited open reduction treatment of proximal phalangeal fracture with miniature external fixator combined with small incision.Methods Between January 2020 and December 2022,29 patients with proximal phalangeal fracture were treated with micro external fixator combined with small incision in fracture plane,in-cluding 23 males and 6 females,aged from 19 to 62 years old with an average of(36.2±21.0)years old.Five patients with open phalangeal fracture were treated with stage Ⅰ surgery,24 cases of closed phalangeal fracture were treated with elective surgery.At the 6 month follow-up,the curative effect was evaluated according to the total active flexion scale(TAFS)of the American Hand Surgery Association.The fracture healing,nail path,local soft tissue healing,and complications were observed.Results All the 29 patients were followed up for 6 to 10 months with an average of(8.3±2.1)months,3 patients had delayed fracture healing,1 patient had distal skin numbness,symptoms were relieved after nutritional nerve treatment,no external fixator broken nails,no infection,the nail path and small incision healing was good,bone healing was achieved at the end of follow-up.Frac-ture healing time ranged from 10 to 24 with an average of(13.7±3.1)weeks.Six months after operation,according to the TAFS standard,19 cases(227.68±4.23)were excellent,7 cases(203.86±14.32)were good,and 3 cases(170.33±7.32)were poor.Conclusion The micro-combined external fixator combined with limited incision with small incision can be used in the treat-ment of proximal phalangeal fracture.The operation is simple and beneficial to early functional exercise,small extensor tendon irritation,convenient second-stage removal,and high rate of excellent and good functional score in recovery period.

Objective To study the application effect of Glisson hepatic pedicle priority approach marked by APR triangle in laparoscopic anatomic right hemihepatectomy(LARH).Methods The clinical data of 66 patients underwent LARH in the Affiliated Hospital of Tangshan Vocational and Technical College were retrospectively analyzed.According to the surgical approaches,the patients were divided into the extrathecal group and the APR group.The 35 patients of the extrathecal group underwent LARH via Glisson hepatic pedicle extrathecal approach.The 31 patients of the APR group were treated with LARH through the Glisson hepatic pedicle priority approach marked by APR triangle.The clinical data including perioperative indexes,postoperative complications,oxidative stress and liver function indexes of patients in the two groups were statistically analyzed,and the differences between the two groups were compared.Results The operative time and intraoperative blood loss of patients in the APR group were significantly shorter/less than those in the extrathecal group,with statistically significant differences(P<0.05).There was no significant differences in the intraoperative blood transfusion ratio,drainage tube indwelling time,first exhaust time,postoperative hospitalization time or postoperative complications of patients between the two groups(P>0.05).The levels of malondialdehyde(MDA),cortisol(Cor)and superoxide dismutase(SOD)at each time point after surgery of patients in the two groups were significantly different from those before surgery(P<0.05),and the levels of MDA,Cor and SOD at each time point after surgery of patients in the APR group were significantly better than those in the extrathecal group(P<0.05).The levels of albumin(ALB),total bilirubin(TBil),aspartate aminotransferase(AST)and alanine aminotransferase(ALT)at each time point after surgery of patients in the two groups were significantly different from those before surgery(P<0.05).Moreover,the levels of ALB,TBil,AST and ALT at each time point after surgery of patients in the APR group were significantly better than those in the extrathecal group(P<0.05).Conclusion Compared with the Glisson hepatic pedicle extrathecal approach,the Glisson hepatic pedicle priority approach marked by APR triangle in LARH has shorter operation time,less bleeding and less oxidative stress reaction,which is beneficial to the recovery of liver function after surgery.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

The enthusiasm of experts was expressed by the effective recovery rate of the questionnaire, the authority coefficient of experts was expressed by the authority coefficient, and the coordination degree of expert opinions was expressed by the coefficient of variation and the Kendall's harmony coefficient.Results:The effective recovery rates of the two rounds of expert correspondence questionnaires were 100.00% (15/15), the expert authority coefficients were 0.880 and 0.900, the coefficient of variation were 0.10-0.26 and 0-0.16 and the Kendall's harmony coefficients were 0.131 and 0.187 ( P<0.01). The final constructed nursing quality evaluation index system for radionuclide wards included three primary indicators, 12 secondary indicators and 56 tertiary indicators. Conclusions:The constructed nursing quality evaluation index system for radionuclide wards is scientific, reliable, practical and specialized, which is close to clinical nursing work and can provide a good evaluation method for nursing quality evaluation in radionuclide wards.

Objective To investigate the correlation between muscle mass and gait parameters in patients with cerebral small vessel disease(CSVD),as well as the impact of reduced muscle mass on the occurrence of falls in CSVD patients.Methods This study was employed a cross-sectional design.Ninety-five inpatients with CSVD confirmed by the Department of Neurology of the Seventh Medical Center of Chinese People's Liberation Army General Hospital from January 1,2022 to June 1,2023 were included consecutively.The 95 patients with CSVD were divided into two groups,namely the reduced muscle mass group and the normal muscle mass group,based on the criteria of appendicular skeletal muscle mass(ASM)≤7.0 kg/m2 for males and ASM ≤5.7 kg/m2 for females as reduced muscle mass.Baseline data(sex,age,years of schooling,number of accompanying diseases[hypertension,hyperlipidemia,diabetes,angina pectoris,myocardial infarction,and migraines]),cognitive function assessment results(mini-mental status examination[MMSE],verbal fluency test[VFT],clock drawing test[CDT],and trail-making test part-B[TMT-B]),gait characteristics(basic gait parameters[gait speed,stride time,stride length,stride frequency]and reanalysis gait parameters[variation coefficient of gait speed,stride time,stride length,stride frequency,and time-phase coordination index,gait asymmetry index]),CSVD imaging findings(cerebral microbleeds,lacunar infarcts,and white matter hyperintensities),and history of falls.The differences in baseline data,cognitive function assessment results,and gait characteristics between the reduced muscle mass group and the normal muscle mass group were compared and analyzed.Linear regression was used to analyze the correlation between muscle mass and gait parameters.The 95 CSVD patients were divided into fall group and non-fall group,and the differences in baseline data,cognitive function assessment results,gait characteristics,CSVD imaging findings,and muscle mass between the two groups were compared.Binary Logistic regression analysis was used to evaluate the impact of reduced muscle mass on falls.Results(1)The majority of patients in the reduced muscle mass group were females(67.7％[21/31]).There was a statistically significant difference in the sex distribution between the reduced muscle mass group and the normal muscle mass group(x2=6.143,P=0.013).There were no statistically significant differences in the other baseline characteristics and cognitive function between the two groups(all P＞0.05).(2)Compared to the normal muscle mass group,patients in the reduced muscle mass group had slower gait speed([0.72±0.16]m/s vs.[0.94±0.15]m/s),longer stride time([1.22±0.12]s vs.[1.08±0.08]s),shorter stride length([0.84±0.19]m vs.[1.00±0.14]m),and lower step frequency([100±9]steps/min vs.[112±8]steps/min).The coefficients of variation for gait speed(11.579[8.163,15.870]％vs.7.304[5.873,9.959]％),stride time(3.876[2.778,5.769]％vs.2.480[1.874,3.001]％),stride length(7.800[5.400,10.700]％vs.5.600[4.100,7.950]％),step frequency(5.313[3.568,7.272]％vs.3.674[3.099,5.082]％),and time-phase coordination index(5.894[4.392,9.080]％vs.3.828[3.031,5.972]％)were all increased,and the differences were statistically significant(all P＜0.05).There was no statistically significant difference in gait asymmetry index between the two groups(P＞0.05).Further analysis with sex and lacunar infarction as potential confounding factors showed that there were statistically significant differences in baseline gait parameters between the normal muscle mass group and the reduced muscle mass group(all P＜0.01).In the reanalysis of gait parameters,only the differences in the coefficients of variation for gait speed and stride time were statistically significant(both P＜0.05).(3)When analyzing ASM as a continuous variable,age and CDT as potential confounders,and stratifying by sex,the results showed that in male patients,baseline gait parameters(gait speed,stride time,stride length,and step frequency with 95％CI ranging from 0.057 to 0.152,-0.105 to-0.023,0.013 to 0.097,and 1.686 to 8.854,respectively),as well as coefficients of variation for stride time(95％CI-0.016 to-0.003)and stride length(95％CI-0.026 to-0.006),were correlated with muscle mass reduction(all P＜0.05).In female patients,gait speed(95％CI0.034 to 0.166)and coefficient of variation for gait speed(95％CI-0.059 to-0.010),stride time(95％CI-0.110 to-0.011),coefficient of variation for stride time(95％CI-0.025 to-0.001),and stride length(95％CI 0.018 to 0.163)were correlated with muscle mass reduction(all P＜0.05).(4)Muscle mass reduction was an independent risk factor for falls(OR,5.044,95％CI 1.840 to 13.827,P=0.002).Conclusions The preliminary analysis of this study suggests that there is a certain correlation between muscle mass and gait parameters in patients with CSVD.Additionally,the study indicates that a decrease in muscle mass among CSVD patients may increase the risk of falls.Therefore,it is important to prioritize the management of muscle mass in CSVD patients.

Objective:To explore the clinical correlation and prognostic value of the Albumin-Bilirubin(ALBI)score in children with secondary hemophagocytic syndrome(sHLH).Methods:A retrospective analysis was conducted on the data of children's sHLH cases clearly diagnosed in the Affiliated Hospital of Zunyi Medical University from January 2012 to March 2023.Survival analysis was conducted according to the ALBI classification.Spearman correlation analysis was conducted between the ALBI score and clinical indicators.The Receiver Operating Characteristic(ROC)curve was used to evaluate the ALBI score,select the best cutoff value,and evaluate the accuracy of prognostic prediction value.Kaplan-Meier method was used to draw the survival curve.Log-rank method was used to compare the differences of survival curve between groups.Cox regression was used for prognostic analysis and restricted cubic spline curves used to calculate the relationship between ALBI scores and the risk of death in children with sHLH.Results:A total of 128 children with sHLH were included in this study,with a median age of 38(13.25,84)months.There were 70 males(54.69％)and 58 females(45.31％).The survival analysis results of ALBI grading showed that the survival rate of HLH patients with ALBI grade 3 was significantly lower than those with ALBI grades 1 and 2.Spearman correlation analysis results showed that ALBI score was positively correlated with splenomegaly,respiratory failure,disseminated intravascular coagulation(DIC),pulmonary hemorrhage,gastrointestinal hemorrhage,central nervous system involvement,ALT,AST,TG,LDH,PT,APTT,and SF(the correlation coefficients are:r=0.181,0.362,0.332,0.221,0.351,0.347,0.391,0.563,0.180,0.448,0.483,0.37,0.356),and was negatively correlated with HB,PLT,and FIB(the correlation coefficients are:r=-0.321,-0.316,-0.423),but was not significantly correlated with EBV infection,fungal infection,hepatomegaly,and ANC(P＞0.05).Using the ROC curve,the cutoff value of ALBI was-1.76.Single factor Cox regression analysis results showed that HB＜90 g/L,ALT ≥ 80 U/L,AST≥200 U/L,LDH ≥1 000 U/L,PT ≥20 s,APTT≥40 s,FIB＜1.5 g/L,ALBI ≥-1.76,combined pulmonary hemorrhage,DIC,central nervous system involvement,gastrointestinal bleeding,and not using blood purification may be the prognostic risk factors for children with sHLH(P＜0.05).Multivariate Cox regression results showed that FIB＜1.5 g/L(HR=2.119,95％CI:1.028-4.368),ALBI≥-1.76(HR=2.452,95％CI:1.233-4.875),and central nervous system involvement(HR=4.674,95％CI:2.486-8.789)were independent risk factors affecting prognosis,while blood purification(HR=0.306,95％CI:0.153-0.612)was an independent protective factor for prognosis.The application of restricted cubic splines shows that the risk of death increases with the increase of ALBI score.The area under the ROC curve(AUC)of the ALBI score for predicting the risk of 1-week,2-week,4-week,and overall mortality were 0.825,0.807,0.700,and 0.693,respectively,indicating good predictive performance for early mortality risk.According to subgroup analysis results of clinical manifestations,compared with the ALBI＜-1.76 group,ALBI≥-1.76 was associated with age ≤2 years,EBV infection,HLH-1994/2004 treatment,concomitant respiratory failure,and ANC≤1.0 × 109/L,HB＜90 g/L,PLT＜100 × 109/L,TG≥3.0 mmol/L,LDH ≥ 1 000 U/L,APTT≥40 s,and FIB＜1.5 g/L(P＜0.05).Conclusion:The ALBI score is related to the clinical characteristics and laboratory indicators of sHLH,and can be used as a beneficial indicator for assessing the prognostic risk of sHLH in children.It has good accuracy and clinical application value in predicting the prognosis of sHLH in children.

Objective:Based on the specific cleavage and non-specific "trans-cleavage" activities of the clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein(CRISPR/Cas13), we established a visually amplification-free rapid detection technique of 2019-nCoV nucleic acid. This technique is easily processed with a low detection limit and good specificity.Methods:According to the 2019-nCoV gene sequence, specific CRISPR RNAs were screened and designed by bioinformatics analysis, and then synthesized as universal signal-strained RNA transcription targets in vitro to establish and optimize the reaction system. Moreover, the 2019-nCoV pseudoviral nucleic acid was used as a standard substance to evaluate the detection limit. A total of 65 positive samples were collected from various 2019-nCoV variants, while 48 negative samples included other clinically common respiratory pathogens, such as influenza A virus, influenza B virus, human parainfluenza virus, Klebsiella pneumonia, etc. All samples were tested by quantitative PCR (qPCR), digital PCR, and the method established in this study. The sensitivity and specificity of the newly established method were analyzed and evaluated. Results:With the newly established technique, the detection time for 2019-nCoV nucleic acid could be minimized to 6 minutes. In addition, the detection limit was 14 copies/μl when assisted by the displaying instrument, whereas it increased to 28 copies/μl with the naked eye. This technique had a sensitivity and specificity of 98.5% (66/67) and 100% (46/46) respectively, showing no statistically significant difference compared to the gold standard qPCR( P=1). Conclusions:This study has successfully established a CRISPR/Cas13a-based visually rapid detection technique for 2019-nCoV nucleic acid. This technique offers the advantages of a simple process, convenient operation, low environmental operating requirements, a detection limit close to qPCR, and a strong potential for on-site testing applications.
