ObjectiveTo investigate the effect of Qingrun prescription（QRP）-containing serum on improving insulin resistance in HepG2 cells and its potential mechanisms. MethodsAn insulin resistance model was established in HepG2 cells with 1×10^-6 mol·L^-1 insulin. Branched-chain α-keto acid dehydrogenase （BCKDH） gene silencing was achieved using siRNA， and the cells were divided into 8 groups： normal group， model group （1×10^-6 mol·L^-1 insulin）， metformin group （1 mmol·L^-1 metformin）， high-， medium-， and low-dose QRP groups （20%， 10%， and 5% QRP-containing serum， respectively）， QRP + siRNA-silenced BCKDH （si-BCKDH） group （10% QRP-containing serum + si-BCKDH）， and QRP + si-NC group （10% QRP-containing serum + si-NC）. Glucose levels in the supernatant were measured with a glucose assay kit， while glycogen content was assessed using a glycogen assay kit. Levels of branched-chain amino acids （BCAAs） and branched-chain keto acids （BCKAs） were determined using ultra-high performance liquid chromatography-tandem mass spectrometry （UHPLC-MS/MS）. mRNA transcription and protein expression levels of BCKDH， dishevelled， Egl-10， and pleckstrin （DEP） domain-containing mammalian target of rapamycin （mTOR）-interacting protein （DEPTOR）， mTOR， and ribosomal protein S6 kinase 1 （S6K1） were detected using real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultsCompared to the normal group， the model group exhibited significantly decreased glucose consumption and glycogen content， increased levels of BCAAs and BCKAs， downregulated expression of BCKDH and DEPTOR， and upregulated mTOR and S6K1 expression （P<0.01）. In comparison to the model group， QRP treatment at all doses significantly enhanced glucose consumption and glycogen content while reducing BCAAs and BCKAs levels （P<0.01）. The high- and medium-dose QRP groups demonstrated significant upregulation of BCKDH mRNA transcription and protein expression， as well as DEPTOR mRNA transcription. Moreover， the DEPTOR protein expression level was significantly increased in high-， medium-， and low-dose QRP groups， while mTOR and S6K1 mRNA and protein expression levels were markedly downregulated （P<0.05， P<0.01）. Compared to the QRP + si-NC group， the QRP + si-BCKDH group exhibited increased BCAAs and BCKAs levels， significantly decreased BCKDH mRNA transcription and protein expression， downregulated DEPTOR mRNA and protein expression， and upregulated mTOR and S6K1 mRNA and protein expression （P<0.05， P<0.01）. ConclusionQRP may improve insulin resistance by reprogramming BCAAs metabolism. This effect involves upregulating BCKDH， reducing BCAAs and BCKAs levels， and suppressing the mTOR pathway activation.

This study aims to investigate the mechanism of Qingrun Decoction in alleviating hepatic insulin resistance in type 2 diabetes mellitus(T2DM) rats through the reprogramming of amino acid metabolism. A T2DM rat model was established by inducing insulin resistance through a high-fat diet combined with intraperitoneal injection of streptozotocin. The model rats were randomly divided into five groups: model group, high-, medium-, and low-dose Qingrun Decoction groups, and metformin group. A normal control group was also established. The rats in the normal and model groups received 10 mL·kg~(-1) distilled water daily by gavage. The metformin group received 150 mg·kg~(-1) metformin suspension by gavage, and the Qingrun Decoction groups received 11.2, 5.6, and 2.8 g·kg~(-1) Qingrun Decoction by gavage for 8 weeks. Blood lipid levels were measured in different groups of rats. Pathological damage in rat liver tissue was assessed by hematoxylin-eosin(HE) staining and oil red O staining. Transcriptome sequencing and untargeted metabolomics were performed on rat liver and serum samples, integrated with bioinformatics analyses. Key metabolites(branched-chain amino acids, BCAAs), amino acid transporters, amino acid metabolites, critical enzymes for amino acid metabolism, resistin, adiponectin(ADPN), and mammalian target of rapamycin(mTOR) pathway-related molecules were quantified using quantitative real-time polymerase chain reaction(qRT-PCR), Western blot, and enzyme-linked immunosorbent assay(ELISA). The results showed that compared with the normal group, the model group had significantly increased serum levels of total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), and resistin and significantly decreased ADPN levels. Hepatocytes in the model group exhibited loose arrangement, significant lipid accumulation, fatty degeneration, and pronounced inflammatory cell infiltration. In liver tissue, the mRNA transcriptional levels of solute carrier family 7 member 2(Slc7a2), solute carrier family 38 member 2(Slc38a2), solute carrier family 38 member 4(Slc38a4), and arginase(ARG) were significantly downregulated, while the mRNA transcriptional levels of solute carrier family 1 member 4(Slc1a4), solute carrier family 16 member 1(Slc16a1), and methionine adenosyltransferase(MAT) were upregulated. Furthermore, the mRNA transcription and protein expression levels of branched-chain α-keto acid dehydrogenase E1α(BCKDHA) and DEP domain-containing mTOR-interacting protein(DEPTOR) were downregulated, while mRNA transcription and protein expression levels of mTOR, as well as ribosomal protein S6 kinase 1(S6K1), were upregulated. The levels of BCAAs and S-adenosyl-L-methionine(SAM) were elevated. The serum level of 6-hydroxymelatonin was significantly reduced, while imidazole-4-one-5-propionic acid and N-(5-phospho-D-ribosyl)anthranilic acid levels were significantly increased. Compared with the model group, Qingrun Decoction significantly reduced blood lipid and resistin levels while increasing ADPN levels. Hepatocytes had improved morphology with reduced inflammatory cells, and fatty degeneration and lipid deposition were alleviated. Differentially expressed genes and differential metabolites were mainly enriched in amino acid metabolic pathways. The expression levels of Slc7a2, Slc38a2, Slc38a4, and ARG in the liver tissue were significantly upregulated, while Slc1a4, Slc16a1, and MAT expression levels were significantly downregulated. BCKDHA and DEPTOR expression levels were upregulated, while mTOR and S6K1 expression levels were downregulated. Additionally, the levels of BCAAs and SAM were significantly decreased. The serum level of 6-hydroxymelatonin was increased, while those of imidazole-4-one-5-propionic acid and N-(5-phospho-D-ribosyl)anthranilic acid were decreased. In summary, Qingrun Decoction may improve amino acid metabolism reprogramming, inhibit mTOR pathway activation, alleviate insulin resistance in the liver, and mitigate pathological damage of liver tissue in T2DM rats by downregulating hepatic BCAAs and SAM and regulating key enzymes involved in amino acid metabolism, such as BCKDHA, ARG, and MAT, as well as amino acid metabolites and transporters.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

OBJECTIVES: This study aims to analyze the clinical symptoms and imaging manifestations in patients with temporomandibular disorder syndrome (TMD), who are sensitive to sudden temperature drop. METHODS: One hundred and nineteen patients with TMD who attended the Department of Stomatology of the First Medical Center of Chinese People's Liberation Army General Hospital from December 2022 to December 2023 were included, including 44 males and 75 females, with a mean age of 32.4±13.7 years.The questionnaire was used to determine whether they were sensitive to temperature drop, and the TMD patients were divided into a temperature plunge-sensitive group and a temperature drop insensitive group. The clinical symptoms and imaging manifestations of patients in the two groups were observed. SPSS 25.0 was used for statistical analysis. RESULTS: There was no statistically significant difference between the gender and age of patients in the temperature plunge-sensitive group (50 patients) and the insensitivity group (69 patients) (P>0.05). The percentage of patients with pain was slightly higher in the temperature plunge-sensitive group [86.0% (43/50)] than in the insensitive group [68.1% (47/69)], and the difference was statistically significant (χ²=5.031, P=0.025), while the differences in joint murmur and mouth opening limitation between the two groups were not statistically significant. A total of 238 lateral joints were detected in both groups, the percentage of osteoarthropathic imaging changes was significantly higher in the temperature plunge-sensitive group [82.0% (82/100)] than in the insensitive group [53.6% (74/138)] (χ²=20.675, P<0.001). Magnetic imaging showed that the percentage of joint effusion was higher in patients in the temperature plunge-sensitive group [66.0% (33/50)] than in the insensitive group [42.0% (29/69)], and the difference was statistically significant (χ²=5.602, P=0.018). CONCLUSIONS TMD patients with maxillofacial pain symptoms, joint effusions, and abnormal imaging of osteoarticular structures are more likely to be sensitive to sudden temperature drops.

Objective:The pain-relieving effect and safety of compound aminopyrine phenacetin tab-lets,tramcontin(tramadol hydrochloride sustained-release tablets)and dolantin in the early stage of au-tologous tendon reconstruction of the anterior cruciate ligament(ACL)of the knee joint were compared.Methods:Retrospective analysis of postoperative pain and drug analgesia in 45 patients performed by the same group from November 2018 to February 2019.The random area group design was divided into two groups according to whether ACL rupture was combined with meniscal injury,group A was 24 patients with ACL reconstruction of knee joint and group B was 21 patients with ACL fracture combined with me-niscus injury.The two groups were divided into three subgroups respectively according to the actual treat-ment of postoperative analgesic drugs received by the patients,including 4 cases of compound aminopy-rine phenacetin tablets,11 cases of oral tramcontin,9 cases of intramuscular dolantin combined with phenergan in group A;3 cases of compound aminopyrine phenacetin tablets,10 cases of oral tramcontin,and 8 cases of intramuscular dolantin combined with phenergan in group B.When the early postoperative patients complain about pain and actively ask for analgesia.When the patients complained about pain af-ter the operation and actively asked for analgesia,they were randomly given painkillers,tramcontin or do-lantin combined with phenergan to relieve pain.Pain visual analogue scale(VAS)was used to evaluate pain relief and observe the occurrence of adverse reactions.Results:There were no significant dif-ferences in gender,age,body mass index,and time of hospital stay between the two groups of patients(P＞0.05).In the patients who used tramcontin and dolantin combined with phenergan to relieve pain judging by VAS score before and 1 h after taking the drug,it was found that the pain situation of the pa-tient was significantly relieved,and the difference before and after taking the drug had statistical signifi-cance(P＜0.05).Pairwise comparisons of the three drugs applied in the two groups showed significantly greater pain relief in the dolantin combined with phenergan group than in the remaining two drugs.There was no significant difference(P＞0.05).Dolantin was prone to nausea and vomiting,but the application of phenergan was also used to reduce side effects.In terms of adverse reactions,only 1 case of nausea oc-curred in the tramcontin group for simple ACL reconstruction,and none of the patients in the other groups showed serious complications and allergic reactions.Conclusion:Whether in cruciate ligament recon-struction alone or combined with meniscus molding or suture,compound aminopyrine phenacetin tablets,tramcontin,dolantin combined with phenergan can effectively relieve pain.Among the three drugs,do-lantin caused the largest pain relief.At the same time,the combination of phenergan effectively reduced the adverse reactions,such as vomiting and nausea,and increased the drug safety.

The traditional Chinese medicine （TCM） in pediatric care has a long history，proven efficacy，and distinctive characteristics.The China Association of Chinese Medicine has organized a series of youth salons to discuss the clinical advantages of treating diseases.Experts at this seminar proposed that the superior disease categories in pediatric TCM are significant for showcasing the unique strengths and advantages of TCM in the treatment of pediatric diseases，enhancing diagnostic and treatment levels，inheriting TCM knowledge，promoting the integration of TCM and Western medicine，and meeting patients' needs.The strengths of pediatric TCM are summed up as "having what others do not，excelling at what others have，being special in what others excel at，and ensuring safety in what others specialize in." The scope of superiority in pediatric TCM covers multiple systems，including respiratory，digestive，endocrine，psychological，and dermatological systems.This article summarized the advantages of TCM in treating 13 diseases discussed in the salon，such as upper respiratory tract infections，coughs，pneumonia，allergic rhinitis，bronchial asthma，atopic dermatitis，functional dyspepsia，functional constipation，enuresis，marginal short stature，simple obesity，attention deficit hyperactivity disorder，and tic disorders.The overall advantages were reflected in three aspects：First，the holistic concept and treatment based on syndrome differentiation in TCM highlight the advantage of treating the root causes of diseases，making the treatment methodical and precise.Second，most traditional Chinese herbs are natural and have strong safety profiles.Third，TCM treatment methods are abundant，especially the external treatment methods，which are widely used in pediatrics，highly accepted by parents，and have definite efficacy，as well as good safety and compliance.

ObjectiveTo investigate the effect of Tongxinluo capsules on the use of anti-ischemic drugs in patients with chronic coronary syndrome （CCS） of Qi deficiency and blood stasis. MethodA multicenter，prospective cohort study was conducted，with Tongxinluo capsules intervention as the exposure factor. Patients were divided into an exposed group （combination of traditional Chinese and western medicine） and a non-exposed group （western medicine alone），and followed up for one year. The use of anti-ischemic drugs was observed on the day of enrollment and at 3，6，12 months. ResultA total of 186 patients were enrolled，with 128 in the exposed group and 58 in the non-exposed group. There were no statistically significant differences in baseline characteristics between the two groups. At the 3-month follow-up，the types of first-line anti-ischemic drugs used in the exposed group were significantly fewer than those in the non-exposed group （P<0.01），and this difference remained statistically significant at 6 months （P<0.05） but was no longer significant at 12 months. At the 3- and 6-month follow-ups，there were no significant differences between the two groups in the types of second-line anti-ischemic drugs used. However，at the 12-month follow-up，the types of second-line anti-ischemic drugs used in the exposed group were significantly fewer than those in the non-exposed group （P<0.01）. At the 3-month follow-up，both groups showed a reduction in the types of first-line anti-ischemic drugs used compared to baseline （P<0.05），with a more pronounced reduction in the exposed group （P<0.05）. At the 6-month follow-up，the exposed group showed a significant reduction in the types of second-line anti-ischemic drugs used compared to baseline （P<0.05），while no significant changes were observed in the non-exposed group. At the 12-month follow-up，the difference in the types of second-line anti-ischemic drugs between the exposed and non-exposed groups was statistically significant （P<0.05），while there was no significant difference in the types of first-line anti-ischemic drugs. ConclusionTongxinluo capsules can effectively reduce the use of anti-ischemic drugs in patients with CCS of Qi deficiency and blood stasis.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Objective To investigate the predictive value of a decision tree-based machine learning model for prognosis in acute paraquat(PQ)poisoning(APP)patients.Methods A retrospective study was conducted.The clinical data of APP patients from Cangzhou Central Hospital between May 2012 and August 2021 were collected,including gender,age,time from ingestion to gastric lavage,proportion of hemoperfusion,serum PQ concentration,biochemical indicators[white blood cell count(WBC),alanine aminotransferase(ALT),serum creatinine(SCr),serum amylase,and serum potassium],and blood gas indicators[arterial blood lactic acid(Lac),base excess(BE),and arterial partial pressure of oxygen(PaO2)].Patients were divided into a survival group(n = 56)and a death group(n = 74)based on 90-day prognosis,and the clinical data between the two groups were compared.The multivariate Logistic regression analysis was conducted to analyze the risk factors of prognosis in APP patients,and two decision tree models(i.e.,with/without serum PQ concentration)were constructed based on the risk factors.The predictive value was evaluated by the receiver operator characteristic(ROC)curve,and the area under the ROC curve(AUC)of two decision tree models was compared by Hanley&McNeil method.Results The 90-day survival rate of the patients was 43.1%(56/130).Compared with death group,patients in the survival group had lower WBC[×109/L:8.9(7.0,11.6)vs.17.4(11.9,23.1)],ALT[U/L:25.3(21.2,31.8)vs.29.3(23.2,40.3)],SCr[μmol/L:64.0(53.0,74.0)vs.91.0(72.5,141.5)],Lac[mmol/L:2.5(1.4,4.0)vs.7.1(3.7,11.0)],and serum PQ concentration[ng/L:0.3(0.1,0.9)vs.2.9(1.9,8.1)],the difference were statistically significant(all P<0.05),higher BE[mmol/L:-2.5(-4.2,-1.1)vs.-7.2(-10.9,-4.7)]and serum potassium[mmol/L:3.7(3.5,4.0)vs.3.2(2.8,3.7)],the difference were statistically significant(all P<0.05),and patients were younger[years:33.5(26.0,47.8)vs.42.5(26.0,58.0),P<0.05].Univariate Logistic regression analysis showed that age,WBC,ALT,SCr,serum potassium,Lac,BE and serum PQ concentration were independent risk factors of 90-day survival[odds ratio(OR)and 95%confidence interval(95%CI)were 1.03(1.01-1.05),1.30(1.18-1.44),1.04(1.01-1.07),1.02(1.01-1.04),7.59(3.25-17.70),1.64(1.35-1.99),1.51(1.29-1.76),7.00(3.41-14.37),P values were 0.018,<0.001,0.011,<0.001,<0.001,<0.001,<0.001,<0.001].Multivariate Logistic regression analysis with serum PQ concentration showed that WBC,serum potassium,and serum PQ concentration were independent risk factors for 90-day survival[OR and 95%CI were 1.17(1.03-1.33),7.29(1.66-32.01),5.49(2.48-12.13),P values were 0.014,0.008,<0.001].Multivariate Logistic regression analysis without serum PQ concentration showed that age,WBC,serum potassium and BE were independent risk factors for 90-day survival[OR and 95%CI were 1.05(1.01-1.08),1.20(1.07-1.34),3.12(1.01-9.66),1.41(1.16-1.72),P values were 0.008,0.002,0.049,0.001].The decision tree model based on serum PQ concentration and serum potassium showed an AUC of 0.94(95%CI was 0.89-0.98),along with 91.9%sensitivity,89.3%specificity,and 90.0%accuracy.The decision tree model based on WBC,BE,and age showed an AUC of 0.89(95%CI was 0.84-0.95),with 86.5%sensitivity,91.1%specificity,and 88.5%accuracy.Pairwise comparison of the AUC using Hanley&McNeil method demonstrated that no statistical difference between the two decision tree models(Z = 1.34,P = 0.180).Conclusion The decision tree-based models can provide quantitative and intuitive prediction tools for the early detection of prognosis in APP patients in clinical practice.
