Through data collection and collation combined with bibliometrics， this study conducted a series of textual research on Yanghetang， such as the name and origin， the evolution of prescription composition and modern clinical application. Yanghetang was first recorded in Bencao Yidu of WANG Ang in the Qing dynasty. In addition to Yanghetang， there were 3 bynames of Jiawei Yanghetang， Quanshengji Yanghetang and Zhenjun Yanghetang. Regarding the composition of the formula， a total of 4 versions of Yanghetang were collected. The first version is the 5 medicines version of Cervi Cornus Colla， Rehmanniae Radix Praeparata， Cinnamomi Cortex， Zingiberis Rhizoma and Ephedrae Herba in Bencao Yidu. The second version is the 7 medicines version of Waike Zhengzhi Quanshengji， changing Zingiberis Rhizoma to Zingiberis Rhizoma Praeparatum Carbonisata（ZRPC） and adding Sinapis Semen and Glycyrrhizae Radix et Rhizoma（GRR） on the basis of Bencao Yidu， and most of the Yanghetang is of this version. The third version is the 6 medicines version of Wushi Yifang Huibian， that is， on the basis of Bencao Yidu， Zingiberis Rhizoma is changed into ZRPC， and Sinapis Semen is added. The fourth version is the 6 medicines version in Yifang Jiedu， that is， on the basis of Bencao Yidu， Zingiberis Rhizoma is changed into Zingiberis Rhizoma Praeparatum， and GRR Praeparata cum Melle is added. Regarding the dose of Yanghetang， the doses of the medicines in Waike Zhengzhi Quanshengji was converted into the modern doses as follows：37.3 g of Rehmanniae Radix Praeparata， 1.87 g of Ephedrae Herba， 11.19 g of Cervi Cornus Colla， 7.46 g of Sinapis Semen， 3.73 g of Cinnamomi Cortex， 3.73 g of GRR， and 1.87 g of ZRPC. The origins of the above medicines are consistent with the 2020 edition of Chinese Pharmacopoeia. The processing specification of Rehmanniae Radix Praeparata is steaming method， ZRPC is ginger charcoal， Sinapis Semen is the fried products， and the rest of the medicines are raw products. The decoction method was verified by the decoction method in Chonglou Yuyao， which is similar in the time， and it is recommended that the above medicines should be added with 600 mL of water， decocted to 100 mL， and taken warmly 30 min after meal. For each dose， it is recommended to use 1-3 doses per day according to the doctor's advice in combination with clinical practice. The diseases involved in the ancient applications involved 42 diseases in 11 departments， including orthopedics， dermatology and gynecology， which were dominated by Yin-cold syndrome. However， the diseases involved in modern research also include 148 related diseases in 10 departments， such as orthopedics， obstetrics and gynecology， which is consistent with the ancient books. In recent years， the research hotspots of Yanghetang have focused on more than 10 fields， including osteoblasts， malignant tumors， wound healing， traditional Chinese medicine fumigation and so on， which are widely used. It is suitable for comprehensive research and development because of its rational formula composition， clear origin， processing and decoction method， and wide clinical application.

In this study， bibliometric methods were used to systematically investigate the name and origin， the evolution of prescription composition， dose evolution， origin and processing method， decoction method， ancient application， modified application， modern application and other information of Huoxiang Zhengqisan. After research， Huoxiang Zhengqisan， also known as Huoxiang Zhengqitang， was first recorded in Taiping Huimin Hejijufang. The original formula is composed of 41.3 g of Arecae Pericarpium， 41.3 g of Angelicae Dahuricae Radix， 41.3 g of Perilla frutescens（actually Perillae Folium）， 41.3 g of Poria， 82.6 g of Pinelliae Rhizoma， 82.6 g of Atractylodis Macrocephalae Rhizoma， 82.6 g of Citri Reticulatae Pericarpium（actually Citri Exocarpium Rubbum）， 82.6 g of Magnoliae Officinalis Cortex， 82.6 g of Platycodonis Radix， 123.9 g of Pogostemonis Herba， and 103.25 g of Glycyrrhizae Radix et Rhizoma. In this formula， Magnoliae Officinalis Cortex is processed according to the specifications for ginger-processed products， Glycyrrhizae Radix et Rhizoma is processed according to the specifications for stir-fried products， and other herbs are used in their raw products. The botanical sources of the herbs are consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The above herbs are ground into a fine powder with a particle size passing through a No. 5 sieve. For each dose， take 8.26 g of the powdered formula， add 300 mL of water， along with 3 g of Zingiberis Rhizoma Recens and 3 g of Jujubae Fructus， and decoct until reduced to 140 mL. The decoction should be administered hot， with three times daily. To induce sweating， the patient should be kept warm under a quilt， and an additional dose should be prepared and taken if needed. This formula is traditionally used to relieve the exterior and resolve dampness， regulate Qi and harmonize the middle， which is mainly used to treat a series of diseases of digestive and respiratory systems. However， potential adverse reactions， including allergies， purpura and disulfiram-like reactions， should be considered during clinical use. Huoxiang Zhengqisan features a rational composition， extensive clinical application， and strong potential for further research and development.

Objective:To analyze the clinical characteristics of the Chikungunya fever outbreak in Shunde District, Foshan City, Guangdong Province in July 2025 and the risk factors associated with delayed viral RNA clearance.Methods:A total of 562 patients with Chikungunya fever admitted to three designated hospitals in Shunde District from July 10 to 30, 2025 were enrolled. Demographic data, clinical manifestations, and laboratory findings were collected. Patients were categorized into four age groups including minors (<18 years), young adults (18 to 39 years), middle-aged adults (40 to 64 years) and elderly adults (≥65 years). The differences of clinical characteristics among these age groups were analyzed. Intergroup comparisons were performed using chi-square test, one-way analysis of variance, or Kruskal-Wallis H test. Pairwise comparisons between groups were conducted using the Bonferroni or Games-Howell or Dunn method. Binary logistic regression was employed to analyze risk factors associated with delayed viral RNA clearance (>7 days). Results:The mean age of the 562 enrolled Chikungunya fever patients was (44.8±21.3) years. Fever, arthralgia and rash were the three core symptoms, with incidence rates of 87.5% (492/562), 88.4%(497/562) and 69.6%(391/562), respectively. At discharge, only 54.1%(304/562) of patients achieved complete symptom resolution, while 26.5%(149/562) still had arthralgia and 36.1%(203/562) had residual rash. Significant differences were observed among age groups in the incidence of fever ( χ2=9.43, P=0.024), peak body temperature ( F=6.54, P<0.001), incidence of arthralgia ( χ2=26.89, P<0.001), duration of arthralgia ( F=12.68, P=0.001), incidence of rash ( χ2=68.99, P<0.001), rate of residual rash at discharge ( χ2=32.37, P<0.001), lymphocyte count ( F=12.94, P<0.001), platelet count ( F=14.95, P<0.001), and C-reactive protein levels (CRP) ( H=94.18, P<0.001). Further pairwise comparisons revealed that compared to the middle-aged and elderly groups, the minor group had a higher incidence of fever and a lower incidence of arthralgia, and the duration of arthralgia was shorter than the elderly group (all P<0.008 3). Compared with the other three groups, the elderly group had lower incidence and residual rate of rash, and lower platelet counts (all P<0.008 3), and higher levels of CRP (all P<0.05). The elderly group had lower lymphocyte counts compared to the minor and young adult groups (both P<0.05). Significant differences were found among age groups in the time to viral RNA clearance ( F=5.77, P=0.003) and length of hospital stay ( F=11.64, P<0.001), with the elderly group having significantly longer duration for both compared to the other three groups (all P<0.05). Multivariate analysis showed that advanced age (odds ratio ( OR)=1.049, 95% confidence interval ( CI) 1.015 to 1.083), longer duration of fever ( OR=1.529, 95% CI 1.086 to 2.155) and longer duration of arthralgia ( OR=1.927, 95% CI 1.318 to 2.817) were independent risk factors for delayed viral RNA clearance (all P<0.05). Conclusions:Patients with Chikungunya fever in Shunde District primarily present with fever, arthralgia and rash. The incidence and characteristics of these three core symptoms show age-related variations. Elderly patients and those with longer durations of fever or arthralgia are more likely to experience delayed viral clearance.

Objective To observe the effect of emodin on lung injury in rats with stroke associated pneumonia(SAP)through regulating Janus kinase 2(JAK2)/signal transducer and activators of transcription 3(STAT3)signaling pathway.Methods The SAP rat model was established by modified thread embolization method combined with intratracheal injection of Pseudomonas aeruginosa method.The successfully modeled rats were randomly divided into model group,emodin low-and high-dose groups and emodin high-dose+coumermycin(JAK2 activator)group,with 12 rats in each group,and another 12 SD rats were selected as the sham-operated group.After the intervention,the partial pressure of arterial blood gas indexes such as carbon dioxide(PaCO2)and partial pressure of oxygen(PaO2)were measured,the ratio of lung wet/dry mass(W/D)was determined,the inflammatory cell count in the bronchoalveolar lavage fluid(BALF)was detected,the histopathological feature in the lung tissues was observed by hematoxylin-eosin(HE)staining and the pathological injury was scored,enzyme-linked immunosorbent assay(ELISA)was used to detect myeloperoxidase(MPO)activity in the lung tissues and interleukin 6(IL-6)and cyclooxygenase 2(COX-2)levels in BALF and serum,and Western Blot was used to detect the expression of JAK2/STAT3 pathway key proteins in lung tissues.Results Compared with the sham-operated group,the model group rats showed that more obvious pathological injury in lung tissues was seen,and PaCO2 value,ratio of lung W/D,white blood cell count and eosinophils count in BALF,pathological injury score,MPO activity in lung tissues,IL-6 and COX-2 levels in BALF and serum,and ratios of p-JAK2/JAK2 and p-STAT3/STAT3 in lung tissues were significantly increased,and PaO2 value was significantly decreased,the differences being statistically significant(P<0.05);compared with the model group,the emodin low-and high-dose groups rats showed that the pathological injury in lung tissues was reduced,PaCO2 value,ratio of lung W/D,white blood cell count and eosinophils count in BALF,pathological injury score,MPO activity in lung tissues,IL-6 and COX-2 levels in BALF and serum,and ratios of p-JAK2/JAK2 and p-STAT3/STAT3 in lung tissues were all decreased,and PaO2 value was increased,the differences being statistically significant(P<0.05),and the improvement effect was more stronger in high-dose emodin group;coumermycin attenuated the improvement effect of emodin on the above various indexes in the model rats.Conclusion Emodin can reduce the inflammation levels in SAP rats through inhibiting the activation of JAK2/STAT3 signaling pathway,thus reducing the lung tissue damage and improving the lung function of rats.

Objective To investigate the value of secreted frizzled-related protein 1(SFRP1),GATA binding protein 3(GATA3)combined with human papillomavirus deoxyribonucleic acid(HPV-DNA)in predicting the risk of postoperative recurrence of high-grade cervical intraepithelial neoplasia(CIN)with positive thin-prep cytologic test(TCT).Methods A total of 200 patients with high-grade CIN and positive TCT results from July 2021 to July 2023 were selected as study subjects.All patients underwent cervical conization,and were divided into recurrence group and non-recurrence group according to the recurrence status one year after surgery.The clinical data,HPV-DNA viral load,and the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cer-vical tissues were compared between the two groups.The HPV-DNA viral load,SFRP1 mRNA,and GATA3 mRNA expression levels in patients with different CIN grades were compared,and their cor-relations with CIN grade and the risk of postoperative recurrence were analyzed.The predictive val-ues of SFRP1,GATA3,and HPV-DNA for the risk of postoperative recurrence were analyzed.Results Among 200 patients,2 were lost during the follow-up period.The recurrence group(n=30)had higher proportions of CIN grade Ⅲ,glandular involvement,positive surgical margins,high-risk human papillomavirus(HPV),higher HPV-DNA viral load,and a higher proportion of HPV positivity at 6 months after surgery compared with the non-recurrence group(n=168),and the differences were statistically significant(P＜0.05).The relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues of the recurrence group were lower than those of the non-recur-rence group,and the differences were statistically significant(P＜0.001).The HPV-DNA level in pa-tients with CIN grade Ⅲ was higher than that in those with CIN grade Ⅱ,and the relative expres-sion levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were lower than those in patients with CIN grade Ⅱ,and the differences were all statistically significant(P＜0.001).Spearman cor-relation analysis showed that HPV-DNA was positively correlated with CIN grade(P＜0.001),while the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were neg-atively correlated with CIN grade(P＜0.001).Logistic regression analysis showed that HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were independ-ent influencing factors for the risk of postoperative recurrence(P＜0.001).The receiver operating characteristic(ROC)curve results showed that the areas under the curve(AUCs)for predicting the risk of postoperative recurrence by HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were 0.787,0.781,and 0.764,respectively,with sensitivities of 80.00％,76.67％,and 76.67％,and specificities of 74.40％,73.81％,and 67.26％,respec-tively.The AUC for the combined prediction of the risk of postoperative recurrence by the three indica-tors was 0.924,with a sensitivity of 80.00％and a specificity of 93.45％,which was superior to the pre-dictive values of each indicator alone(Z=3.159,3.306,4.018,P＜0.001).Conclusion HPV-DNA,SFRP1,and GATA3 in cervical tissues have certain predictive values for the risk of postoperative re-currence in patients with high-grade CIN and positive TCT results,and combined detection can im-prove the predictive efficacy.
