Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

Objective:To analyze the efficacy of total knee arthroplasty (TKA) with partial varus retention in the treatment of moderate knee varus.Methods:A retrospective analysis was conducted on the data of 613 osteoarthritis patients with moderate knee varus who underwent TKA at the First Affiliated Hospital of Nanjing Medical University from January 2010 to October 2019. According to whether a 2°-3° of knee varus was retained, the patients were divided into the retained varus group and the mechanical alignment group. The retained varus group included 318 cases, with 63 males and 255 females, aged 68.51±6.95 years (range, 46-86 years), and BMI of 26.99±3.66 kg/m 2 (range, 17.40-39.01 kg/m 2). Preoperative Kellgren-Lawrence (K-L) classification of knee osteoarthritis was grade III in 113 cases and grade IV in 205 cases. The mechanical alignment group included 295 cases, with 75 males and 220 females, aged 69.60±7.12 years (range, 52-87 years), and BMI of 26.95±3.94 kg/m 2 (range, 16.60-41.90 kg/m 2). Preoperative K-L classification was grade III in 102 cases and grade IV in 193 cases. Surgical duration, total blood loss, preoperative and postoperative varus angle, lower limb swelling on the fifth postoperative day, and postoperative complications were recorded. Follow-up were arranged at 3 months, 6 months, 1 year, and 5 years postoperatively. At each follow-up point, the visual analogue score (VAS) for knee pain, Hospital for Special Surgery (HSS) score, Forgotten Joint Score (FJS-12), and MOS item short-form health survey (SF-36) were assessed. Results:All 613 patients were successfully followed up, with a follow-up period of 5.25±1.02 years (range, 5.0-6.0 years). There were no statistically significant differences in gender, age, BMI, and K-L classification between the two groups ( P>0.05). The differences in postoperative varus angle, VAS scores, and HSS score were statistically significant from the preoperative values in both groups( P<0.05). The surgical duration of the retained varus group was 77.40±18.55 min, total blood loss was 920.78±407.26 ml, and lower limb swelling on the fifth postoperative day was 1.18±0.51 cm, all of which were lower than those in the mechanical alignment group: 85.31±22.15 min, 1127.14±580.08 ml, 3.22±0.52 cm, respectively, with statistically significant differences ( P<0.05). The VAS scores at postoperative day 5 and 3 months in the retained varus group were 5.08±0.72 and 2.18±1.09, respectively, which were lower than those in the mechanical alignment group: 5.80±0.81, 3.00±1.04, with statistically significant differences ( P<0.05). There were no statistically significant differences in VAS scores at 6 months, 1 year, and 5 years postoperatively between the two groups ( P>0.05). The HSS scores at 3 months and 6 months postoperatively in the retained varus group were 68.57±4.98 and 79.04±3.26, respectively, which were higher than those in the mechanical alignment group: 64.14±3.99, 77.73±4.04, with statistically significant differences ( P<0.05). There were no statistically significant differences in HSS scores at 1 year and 5 years postoperatively between the two groups ( P>0.05). The FJS-12 scores at 3 months and 6 months postoperatively in the retained varus group were 18.06±3.50 and 27.50±1.80, respectively, which were higher than those in the mechanical alignment group: 13.45±2.44, 24.23±1.59, with statistically significant differences ( P<0.05). There were no statistically significant differences in FJS-12 scores at 1 year and 5 years postoperatively between the two groups ( P>0.05). The SF-36 scores at 3 months and 6 months postoperatively in the retained varus group were 40.85±8.07 and 52.15±6.01, respectively, which were higher than those in the mechanical alignment group: 35.87±6.83, 47.28±5.38, with statistically significant differences ( P<0.05). There were no statistically significant differences in SF-36 scores at 1 year and 5 years postoperatively between the two groups ( P>0.05). The incidence of deep vein thrombosis in the lower limbs was 3.8% (12/318) in the retained varus group, which was lower than the 7.8% (23/295) in the mechanical alignment group, with a statistically significant difference ( P<0.05). Conclusion:In osteoarthritis patients with moderate knee varus undergoing TKA, retaining approximately 3° of varus can reduce surgical trauma and total blood loss, shorten surgical duration, alleviate postoperative pain and limb swelling, facilitate functional recovery, and improve patient satisfaction.

GNPS-based mass spectrum-molecular networks is an effective strategy for rapidly identifying known natural products and discovering novel structures. The chemical diversity of azaphilones from the fermentation extracts of Talaromyces sp. HK1-18 was studied by molecular network technique. Three linear tricyclic azaphilones, sequoiamonacins A-C (2a, 2b, 1), were isolated by silica gel column chromatography and high performance liquid chromatography from the extracts of the fungal strain of HK1-18, and their structures were identified by nuclear magnetic resonance and high-resolution mass spectrometry. Guided by the mass spectra of sequoiamonacins A-C (2a, 2b, 1), the cluster of sequoiamonacinoid analogues was discovered from the full molecular networking of HK1-18. By analyzing the MS/MS fragments of each parent ion in this cluster, 7 azaphilones (3-9) included 6 new ones (4-9) were predicted successfully. Then the MS/MS cracking regularity of this type of azaphilones was revealed. Compound 1 showed anti-inflammatory activity, which can inhibit the production of interleukin-1α (IL-1α) in lipopolysaccharide (LPS)-induced mouse macrophage RAW264.7, with an inhibitory rate of 29% at the concentration of 12.5 μg·mL^-1.

The main chemical components of Allii Macrostemonis Bulbus and components in serum were analyzed and identified rapidly and precisely by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS)technique in this study.The compounds were identified based on the relative molecular mass,fragmentation ions,and retention time of chromatographic peaks.A total of 36 kinds of chemical components were identified from Allii Macrostemonis Bulbus,including 28 kinds of saponins,3 kinds of amino acids,2 kinds of flavonoids,one kind of organosulfur compound,one kind of nucleoside,and one kind of hormone-lipid compound.In addition,8 kinds of compounds of Allii Macrostemonis Bulbus were identified from the serum.Based on the intersection compounds of which detected in serum and screened out by TCMSP platform database,by using targeted network pharmacology and molecular docking technology,a"drug-component-target-pathway"association network was constructed.Naringenin,quercetin,macrostemonoside E and 25(R)-26-O-β-D-glucopyranosyl-22-hydroxy-5β-furostan-3-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranoside were screened as the main active constituents of Allii Macrostemonis Bulbus in the treatment of hyperlipidemia.In addition,adenosine 5′-monophosphate-activated protein kinase(AMPK),tumor necrosis factor(TNF),vascular endothelial growth factor A(VEGFA)and matrix metallopeptidase 9(MMP9)were the key action targets for Allii Macrostemonis Bulbus in the treatment of hyperlipidemia.Molecular docking was performed using the main pharmacodynamic components and key action targets.The results indicated that all the four active components showed strongly bound to AMPK.This suggested that the regulation of lipid metabolism might be the key mechanism of Allii Macrostemonis Bulbus in antihyperlipidemic effect.This study provided a data reference for the research on the pharmacodynamic components of Allii Macrostemonis Bulbus,and provided a basis for the improvement of quality standard of Allii Macrostemonis Bulbus.

Objective To design and implement a high-precision ear pulse wave physiological signal detection device for human centrifuge training to solve the problems in measurement and calibration of pilot ear pulse wave signal during human centrifuge training.Methods The high-precision ear pulse wave physiological signal detection device was composed of an ear pulse wave acquisition sensor,a signal acquisition and control unit and a host signal processing module.The ear pulse wave acquisition sensor had an ear-clip-like shape and consisted of an outer shell,an inner shell and an elastic steel plate;the signal acquisition and control unit was made up of an power supply module,a constant voltage module for the light source,a signal acquisition module,a master control module and a data transmission module,which had its software developed with an embedded system;the host signal processing module divided the signal processing into 2 phases of signal pre-processing and pulse wave signal monitoring and display.The detection performance of the device was verified by using a physiological electrical signal calibrator to test the ear pulse wave signals detected with the device;the effectiveness and stability of the device were validated by implementing human centrifuge training experiments with different loads.Results The voltage measurement error,amplitude-frequency characteristics and common mode rejection ratio detected by this device were all within the permitted ranges of JJG 760-2003 Verification Regulation for Electro Cardiac Monitor and JJG 954-2019 Verification Regulation of Digital Electroencephalographs;the device was capable of detecting the ear pulse wave signals of pilot during human centrifuge training in real time with little interference from motion and stable signal quality.Conclusion The device can accurately clarify the changes in the amplitude of the pilot's ear pulse wave during human centrifuge training and effectively reflect the changes in the pilot's cerebral blood flow under positive acceleration.[Chinese Medical Equipment Journal,2024,45(9):35-40]

Objective To explore the efficiency and feasibility of EMG changes for forewarning of G-induced loss of consciou-sness(G-LOC)under G load of human centrifuge.Methods Firstly,seven subjects were selected for high G training and push-pull training with reference to the 2-condition analysis method.Secondly,the characteristics of EMG changes in different parts of the body were analyzed before and after the occurrence of G-LOC in the subjects under the high-G training mode and the push-pull effect.Finally,the changes of two EMG characteristic parameters,including integrated absolute value(IAV)and waveform length(WL),were investigated under two sequential loads to one subject.Results The EMG waveforms of all the subjects were asymmetric and irregular before and after G-LOC.Under the high-G training mode,the changes of EMG characteristic parameters at the gastrocnemius muscle were more valuable than those at the tibialis anterior muscle for G-LOC forewarning;under the push-pull effect,the changes of EMG characteristic parameters were not obvious,and not effective for G-LOC forewarning.The IAV and WL showed characteristic changes under two sequential loads to one subject.Conclusion The changes of EMG characteristic parameters at the gastrocnemius muscle behaved better than those at the tibialis anterior muscle for G-LOC forewarning;the 2-condition analysis method was effective for G-LOC forewarning under the high-G training mode,while not in the presence of a push-pull effect;comparing the changes of EMG characteristic para-meters of some subject under two sequential loads can also be used for G-LOC forewarning.[Chinese Medical Equipment Journal,2024,45(12):25-31]
