This paper summarizes Professor LU Fang's clinical experience in treating systemic lupus erythematosus （SLE） based on the differentiation and treatment of heat-toxin and blood-stasis in the collaterals. SLE is generally characterized by deficiency in origin with excess in manifestation. The core pathogenesis is heat-toxin obstructing the collaterals. During the acute active stage， the predominant pattern is blazing heat-toxin causing blood stasis， while in the chronic remitting stage， the main pattern is toxic stasis blocking the collaterals with qi and yin deficiency. Clinical treatment follows the basic principle that treat with salty-cold herbs， when heat invades internally and that assist with acrid-dispersing herbs when stasis obstructs the collaterals. The self-formulated Yimian Decoction （抑免汤） serves as the base formula and is applied in stages. During the acute active stage， it is often combined with herbs for clearing heat and detoxifying， cooling blood and resolving stasis， and unblocking the collaterals. In the chronic remitting stage， it is often combined with herbs for activating blood circulation and unblocking the collaterals， as well as tonifying qi and nourishing yin.

Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

BACKGROUND:The morphological indexes of ankle point may change after ankle fracture,and there is a certain correlation between the coronal angle change of ankle point and the functional recovery of ankle joint.Most previous studies have studied the height recovery of ankle point after surgery,so the correlation between the fluctuation of coronal angle of ankle point and the functional recovery of ankle joint after ankle fracture has certain reference significance. OBJECTIVE:To investigate the effect of coronal angle change of ankle point on joint function recovery after ankle fracture. METHODS:A total of 86 patients with ankle fracture who underwent surgical treatment were selected as the study objects,and were divided into excellent group(n=45)and poor group(n=41)according to the results of American Orthopaedic Foot&Ankle Society(AOFAS)hindfoot-ankle score during the last follow-up,and the general data of the two groups were compared.The morphological indexes of ankle points on the affected side and healthy side were compared after surgery based on ankle acupoints and lateral X-rays of the ankle joint,including the width and depth of ankle points,coronal angle and sagittal angle,and the difference of ankle points between the affected side and healthy side,and further comparison and analysis were conducted in each group.A joint model was constructed and Cox regression analysis was used to evaluate the relationship between coronal angle fluctuation and joint function recovery.Least absolute shrinkage and selection operator regression method and multivariate Logistic regression were used to analyze the risk factors affecting the recovery of joint function.The patients were divided into 5-quartile array(Q1-Q5)according to the angle of coronal position at ankle point from low to high.The clinical data characteristics of the five groups were compared,and the correlation between the change of coronal position at ankle point and the risk of poor recovery of joint function was analyzed by multivariate Logistic regression.A restricted cubic spline Logistic regression model was established to analyze the dose-response relationship.The prediction model of regression equation y=1-1/(1+e-z)was established and verified. RESULTS AND CONCLUSION:(1)The width and depth of ankle point on the affected side,coronal angle and sagittal angle were significantly higher than those on the healthy side(all P<0.05),and compared with the excellent group,the difference of ankle point width,depth difference,coronal angle difference and sagittal angle difference were greater in the poor group(P<0.05).(2)The combined model showed that the risk of poor joint function was increased by 3%for every 1? increase in coronal angle,regardless of whether the angle was within the normal range.(3)Least absolute shrinkage and selection operator regression and multivariate Logistics regression analysis showed that after adjusting for potential confounding factors,it was found that age,lack of functional exercise in early stage,no calcaneal traction,failure to remove internal fixation,postoperative complications,and increased ankle coronal angle were independent risk factors for joint function recovery(P<0.05).(4)The coronal angle within 3 months after surgery was independently correlated with the risk of poor joint function recovery(OR=1.57,95%CI:1.38-1.76,P=0.002),and the trend test of the coronal angle from low to high quintile in each postoperative period had statistical significance(Ptrend<0.001).(5)Restricted cubic spline model analysis showed that there was no nonlinear relationship between the coronal angle change of ankle point and the risk of poor joint function recovery in males or females.Through Bootstrap self-sampling,the prediction model has good differentiation and accuracy.(6)The reduction of coronal angle of ankle point after ankle fracture plays a significant role in promoting the recovery of joint function.Therefore,the detection of coronal angle of ankle point after ankle fracture is helpful to understand the recovery of joint function of patients.

A 20-year-old male patient presented to the Department of Dermatology of Peking Union Medical College Hospital with complaints of an 8-year history of facial scarring, swelling of the lower limbs, and a 4-year history of scalp thickening. Physical examination showed thickening furrowing wrinkling of the skin on the face and behind the ears, ciliary body hirsutism, blepharoptosis, and cutis verticis gyrate. Both lower limbs were swollen, especially the knees and ankles. The skin of the palms and soles of the feet was keratinized and thickened. Laboratory examination using bone and joint X-ray showed periostosis of the proximal middle phalanges and metacarpals of both hands, distal ulna and radius, tibia and fibula, distal femurs, and metatarsals.Genetic testing revealed two variants in SLCO2A1, c.1658T > A and c.96+4A > C.Through multidisciplinary consultation, we confirmed the diagnosis of pachydermoperiostosis.

ObjectiveTo investigate the ameliorative effect of paeonol on acute alcohol-induced hepatic inflammation in mice via the regulation of the short-chain fatty acids （SCFAs）-specific receptor GPR43/mitogen-activated protein kinase （MAPK） signaling pathway. MethodsC57BL/6 mice were randomly divided into five groups： blank control group， model group， low-dose paeonol group （120 mg·kg^-1）， high-dose paeonol group （480 mg·kg^-1）， and silybin group （36.8 mg·kg^-1）. A mouse model of alcohol-induced liver disease （ALD） was established by ad libitum administration of a Lieber-DeCarli alcohol liquid diet. Serum lipid levels， liver function， inflammatory cytokines， and oxidative stress markers were measured. Liver hematoxylin-eosin （HE） staining and Oil Red O staining were performed to validate successful modeling. Western blot analysis was used to assess the expression levels of zonula occludens-1 （ZO-1）， Claudin-1， and proteins related to the GPR43/MAPK signaling pathway in the colonic tissue. Immunohistochemistry was employed to detect the protein expression of GPR43， ZO-1， and Claudin-1 in the colon. Then 16S rDNA sequencing was performed to analyze differences in intestinal flora between the model group and the high-dose paeonol group. Additionally， fecal microbiota transplantation （FMT） experiments were conducted to validate the regulatory effect of paeonol on ALD via modulation of intestinal flora. ResultsCompared with the blank control group， the model group showed significantly elevated serum lipid levels， oxidative stress， and inflammatory cytokine expression （P<0.01）. Liver histology revealed increased inflammatory infiltration and lipid droplet accumulation. Colonic mucosal injury and impaired intestinal barrier function were observed. Levels of MAPK pathway-related proteins in the colonic tissue were upregulated （P<0.01）， while GPR43， ZO-1， and Claudin-1 protein expression levels were significantly decreased （P<0.01）. The composition and abundance of the intestinal flora were markedly altered， with a reduced Bacteroidetes-to-Firmicutes ratio and decreased relative abundances of Eubacterium， Parabacteroides， Erysipelothrix， and Adlercreutzia， alongside increased abundances of Clostridium butyricum， Enterococcus， and Helicobacter pylori in the model group. Compared with the model group， paeonol significantly reduced serum lipid levels， oxidative stress responses， and the expression of inflammatory cytokines in ALD mice （P<0.05， P<0.01）. It also attenuated hepatic lipid accumulation， restored intestinal barrier function， and repaired the structural integrity of liver and colonic tissues. The protein expression levels of ZO-1， Claudin-1， and GPR43 in the colonic tissue were significantly increased （P<0.05， P<0.01）， while those of MAPK pathway-related proteins were significantly decreased （P<0.05， P<0.01）. The intestinal flora dysbiosis was effectively alleviated， rendering its composition closer to that of normal mice. The efficacy of paeonol in modulating ALD was further confirmed by FMT experiments， supporting its mechanistic involvement in the SCFAs-GPR43/MAPK signaling pathway. ConclusionPaeonol exerts a protective effect against ALD in mice， which may be mediated through regulation of the SCFAs-GPR43/MAPK signaling pathway， thereby achieving anti-inflammatory effects and improving intestinal barrier function.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

Background: The genetic basis for hyperglycaemia in pregnancy remain unclear. This study aimed to uncover the genetic determinants of gestational diabetes mellitus (GDM) and investigate their applications. Methods: We performed a meta-analysis of genome-wide association studies (GWAS) for GDM in Chinese women (464 cases and 1,217 controls), followed by de novo replications in an independent Chinese cohort (564 cases and 572 controls) and in silico replication in European (12,332 cases and 131,109 controls) and multi-ethnic populations (5,485 cases and 347,856 controls). A polygenic risk score (PRS) was derived based on the identified variants. Results: Using the genome-wide scan and candidate gene approaches, we identified four susceptibility loci for GDM. These included three previously reported loci for GDM and type 2 diabetes mellitus (T2DM) at MTNR1B (rs7945617, odds ratio [OR], 1.64; 95% confidence interval [CI],1.38 to 1.96]), CDKAL1 (rs7754840, OR, 1.33; 95% CI, 1.13 to 1.58), and INS-IGF2-KCNQ1 (rs2237897, OR, 1.48; 95% CI, 1.23 to 1.79), as well as a novel genome-wide significant locus near TBR1-SLC4A10 (rs117781972, OR, 2.05; 95% CI, 1.61 to 2.62; Pmeta=7.6×10-9), which has not been previously reported in GWAS for T2DM or glycaemic traits. Moreover, we found that women with a high PRS (top quintile) had over threefold (95% CI, 2.30 to 4.09; Pmeta=3.1×10-14) and 71% (95% CI, 1.08 to 2.71; P=0.0220) higher risk for GDM and abnormal glucose tolerance post-pregnancy, respectively, compared to other individuals. Conclusion Our results indicate that the genetic architecture of glucose metabolism exhibits both similarities and differences between the pregnant and non-pregnant states. Integrating genetic information can facilitate identification of pregnant women at a higher risk of developing GDM or later diabetes.

BACKGROUND:Hydroxy safflower yellow A has anti-ischemia,anti-oxidation,anti-thrombotic and anti-inflammatory effects.Whether it affects neuronal pyroptosis after glucose-oxygen deprivation/reglucose-reoxygenation is still unclear. OBJECTIVE:To investigate the protective effect of hydroxy safflower yellow A on neuronal pyroptosis and its mechanism. METHODS:HT22 cells in logarithmic growth phase were randomly divided into five groups:normal group,model group,hydroxy safflower yellow A group,colivelin group,and colivelin+hydroxy safflower yellow A group.HT22 cells were treated with glucose-oxygen deprivation/reglucose-reoxygenation to establish neuronal pyroptosis model,and then treated with STAT3 agonist Colivelin and hydroxy safflower yellow A.JC-1 probe was employed to assess changes in mitochondrial membrane potential.Reactive oxygen species kit was used to determine the content of reactive oxygen species in cells.GSDMD/TUNEL staining was conducted to observe cell pyroptosis.Immunofluorescence analysis was performed to detect STAT3 and GSDMD protein expression.RT-PCR was utilized for assessing mRNA expression levels of STAT3,NLRP3,and Caspase-1.Western blot assay was utilized to measure the protein expression levels of p-STAT3,NLRP3,GSDMD,Cleaved-caspase-1,and interleukin-1β. RESULTS AND CONCLUSION:(1)Compared with the normal group,the number of pyroptotic cells increased in HT22 cells in the model group along with a significant increase in protein expression levels of p-STAT3,NLRP3,Cleaved-caspase-1,GSDMD,and interleukin-1β.Compared with the model group,the number of pyroptotic cells reduced,and the expression of pyroptosis-related proteins significantly decreased in the hydroxy safflower yellow A group.(2)In comparison with the model group,pyroptosis worsened in the colivelin group where mitochondrial membrane potential decreased along with elevated reactive oxygen species content and increased mRNA expression levels of STAT3,NLRP3,and Caspase-1,as well as increased protein expression levels of p-STAT3,NLRP3,GSDMD,Cleaved-caspase-1,and interleukin-1β.Compared with the Colivelin group,above indexes were improved in the colivelin+hydroxy safflower yellow A group.These results suggest that hydroxy safflower yellow A plays a neuroprotective role through STAT3 signaling pathway to inhibit HT22 pyroptosis after glucose-oxygen deprivation/reglucose-reoxygenation treatment.

ObjectiveBased on analytic hierarchy process（AHP）-criteria importance through intercriteria correlation（CRITIC） hybrid weighting method， grey relational analysis and backpropagation artificial neural network（BP-ANN）， to optimize the water extraction process of Qizhi prescription， so as to provide an experimental basis for optimization of the preparation process of this prescription and the establishment of quality standards. MethodsL₉（3⁴） orthogonal test was employed， and the AHP-CRITIC hybrid weighting method was utilized to determine the weight coefficients of the quality fractions of various components， including astragaloside Ⅳ， polygalaxanthone Ⅲ， calycosin-7-O-β-D-glucoside， tenuifolin， and 3，6′-disinapoylsucrose， as well as the dry extract yield. The comprehensive score of each factor level combination in the orthogonal test were calculated as evaluation indicator to select the optimal extraction process parameters. The effects of extraction times， extraction time， and solvent dosage on the aqueous extraction process of the formula were investigated through intuitive analysis， variance analysis， and grey relational analysis. Meanwhile， a BP-ANN model was established to reverse-predict the optimal extraction process parameters of Qizhi prescription， and the optimized process parameters were validated. ResultsThe weight coefficients of the five index components（astragaloside Ⅳ， tenuifolin， calycosin-7-O-β-D-glucoside， polygalaxanthone Ⅲ， and 3，6′-disinapoylsucrose） and dry extract yield were 25.7%， 20.82%， 16.41%， 12.45%， 15.96% and 8.67%， respectively. The optimized extraction process parameters were extracted 3 times with 8， 6， 6 times the amount of water， each time for 1 h. The network prediction results of BP-ANN test samples were consistent with the orthogonal test results， and the mean square error（MSE） of the predicted and measured values of the network was <1%. The water extraction process of Qizhi prescription analyzed and predicted by relevant mathematical models was stable and feasible， which could effectively improve the extraction efficiency of the active ingredients of Astragali Radix and Polygalae Radix， and the average comprehensive score of the validation test was 90.85 with the relative standard deviation（RSD） of 1.55%. ConclusionThis study establishes a water extraction process for compound Qizhi granules， and the optimized extraction process can effectively improve the extraction efficiency of active ingredients， which provides useful references for the optimization of preparation process and the establishment of quality standards for other clinical experience formulas.
