Employing bibliometric methods and adhering to principles of textual research， this study systematically investigated prescription source， formula name， composition evolution， dose evolution， origin， processing， ancient and modern applications of Xiaofengsan. Xiaofengsan， also known as Renshen Xiaofengsan and Chantui Xiaofengsan， was first recorded in the Taiping Huimin Hejijufang（hereafter referred to as Jufang） of the Southern Song dynasty. The formula composition included Schizonepetae Spica， Glycyrrhizae Radix et Rhizoma， Chuanxiong Rhizoma， Notoptery Rhizoma et Radix， Bombyx Batryticatus， Saposhnikoviae Radix， Poria， Cicadae Periostracum， Pogostemonis Herba， Ginseng Radix et Rhizoma， Magnoliae Officinalis Cortex and Citri Reticulatae Pericarpium， a total of 12 medicinal materials. In terms of the evolution of formula composition， formulas across dynasties largely aligned with those recorded in Jufang， with only minor variations in application. The results of the formula dosage research indicated that one dose of medication in Jufang corresponded to the following modern dosages：Schizonepetae Spica of 82.6 g， Glycyrrhizae Radix et Rhizoma of 82.6 g， Chuanxiong Rhizoma of 82.6 g， Notoptery Rhizoma et Radix of 82.6 g， Bombyx Batryticatus of 82.6 g， Saposhnikoviae Radix of 82.6 g， Poria of 82.6 g， Cicadae Periostracum of 82.6 g， Pogostemonis Herba of 82.6 g， Ginseng Radix et Rhizoma of 82.6 g， Magnoliae Officinalis Cortex of 20.65 g and Citri Reticulatae Pericarpium of 20.65 g， the origins of all the constituent drugs were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The results of the investigation into the decoction method indicated that the aforementioned drugs should be finely ground into powder（pass through the No.5 sieve）， and 8.26 g was taken for each dose， which was taken with the clear liquid obtained by steeping tea leaves in boiling water for several minutes. This mixture was administered three times daily， 30 min after meals. The ancient functional indications of this formula mainly involved dispelling wind-heat， eliminating pathogenic factors and regulating the middle Jiao. It primarily treated all wind-heat syndromes manifesting as skin diseases， predominantly affecting the upper body， especially the head and face. The diseases involved in modern applications were mostly dermatological diseases， including urticaria， eczema， atopic dermatitis and others. In this paper， by combing the relevant ancient literature， the key information of Xiaofengsan was textual researched， in order to provide reference for the modern application and development of this formula.

This paper summarized professor ZHANG Zhen's clinical experience in treating rheumatoid arthritis （RA） complicated with anemia using self-formulated Yisui Shengxue Decoction （益髓生血汤） with modifications. It is proposed that the core pathogenesis of this condition is rooted in spleen and kidney depletion with insufficiency of essence and blood， while pathogenic dampness obstruction and internal blood stasis accumulation are the branches. The treatment principle focuses on tonifying the spleen and kidney， replenishing essence and nourishing the marrow， and enriching and generating blood， while simultaneously removing dampness and unblocking collaterals， activating blood and dissolving stasis. Based on this approach， Yisui Shengxue Decoction is used as the basic prescription， with flexible modifications according to syndrome patterns and clinical manifestations. For deficiency of both qi and blood combined with damp turbidity syndrome， medicinals that tonify qi and nourish blood， fortify the spleen and eliminate dampness， and mildly disperse obstruction are added. For wind-cold-dampness bi （痹） syndrome， medicinals that dispel wind and disperse cold， remove dampness and unblock the collaterals are incorporated. For wind-dampness-heat bi syndrome， medicinals that clear heat and eliminate dampness， unblock the collaterals and relieve bi are selected. For blood stasis obstructing the collaterals syndrome， medicinals that activate blood and resolve stasis， unblock the collaterals and relieve pain are combined. For yin deficiency with internal heat syndrome， medicinals that nourish yin and clear heat， cool blood and unblock the collaterals are prescribed.

Sesquiterpenes are natural terpenes containing 15 carbon atoms. They are widely used in the perfume, pharmaceutical, and biofuel industries due to their remarkable biological activities. The traditional production of sesquiterpenes relies on chemical synthesis or plant extraction, which has the disadvantages of low yields and waste of resources. The construction of microbial cell factories for the efficient synthesis of sesquiterpenes by means of synthetic biology provides a new option. In recent years, with the development of metabolic engineering and synthetic biology, the heterologous synthesis of a variety of sesquiterpenes has been successfully achieved by metabolic engineering of the oleaginous yeast, Yarrowia lipolytica. In this paper, we review the research progress in the heterologous synthesis of different sesquiterpenes by Y. lipolytica, discuss the synthetic biology strategies commonly used in this field, and make an outlook on the research directions and engineering approaches to further enhance the sesquiterpene yield in this host. This paper provides a reference for strategies such as synergistic optimization of synthetic biology and metabolic engineering, enhanced precursors, and opens up new directions for the application of synthetic biology in green chemistry and sustainable production.

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 This study aims to monitor the mRNA ratio of podocin to nephrin (PNR) in glomerular podocytes of early diabetic kidney disease (DKD) rat models. The feasibility of using PNR as an early diagnostic indicator for DKD was evaluated by comparing it with the urinary albumin-to-creatinine ratio (U-ACR). Additionally, the early intervention effects of valsartan and fosinopril sodium on DKD were compared. Methods The DKD rat model was established by caudal intravenous injection of streptozotocin (STZ) at a dosage of 60 mg/kg. The early changes in PNR and U-ACR were monitored and compared, followed by timely intervention with valsartan and fosinopril sodium. Hematoxylin and eosin staining (HE) was used to observe glomerular structure, while transmission electron microscopy examined the ultrastructure of glomerular podocytes. ResultsPNR reached the critical value(≥1) on day 9 after modeling, earlier than U-ACR, which reached the critical value(≥30 mg/g) on day 15. Intervention with valsartan and fosinopril sodium on day 9 after modeling significantly reduced U-ACR (P < 0.05), with low-dose valsartan showing better results than high-dose (P>0.05), while high-dose fosinopril sodium outperformed low-dose (P>0.05). Both low doses of valsartan and fosinopril sodium significantly reduced PNR (P<0.05), with no significant effect observed for high doses. The interventions with valsartan and fosinopril sodium improved and maintained glomerular structure and podocyte arrangement. ConclusionPNR changes earlier than U-ACR, indicating its potential as an early diagnostic marker for DKD in rats. Early intervention with valsartan and fosinopril sodium demonstrates a therapeutic effect on DKD in rats.

OBJECTIVE To investigate the effect of gene polymorphism on opioid-induced constipation. METHODS The target genes related to opioid-induced constipation were screened out through searching guidelines， databases and evidence-based medical data， and then 100 cancer pain patients who received opioid drugs for analgesia were included as the study subjects. According to whether there were adverse effects of constipation after medication or not， they were divided into test group and control group， with 50 cases in each group. The target gene was detected by PCR or fluorescence in situ hybridization. The SNPStats program was used to carry out Hardy-Weinberg balance test and correlation analysis between gene polymorphism and opioid-induced constipation. The multivariate Logistic regression analysis was used to explore the relevant predictive factors of opioid-induced constipation， and receiver operating characteristic （ROC） curve of subjects was drawn to analyze the effectiveness of each predictive factor in predicting opioid-induced constipation. RESULTS CYP2D6， CYP3A5*3， ABCB1 and OPRM1 were selected as target genes for detection. The results of genotype detection showed that the frequency distribution of CYP2D6 （rs1065852， rs1135822， rs16947， rs28371725， rs28371735）， CYP3A5*3 （058rs776746）， ABCB1 （062rs1045642）， OPRM1 （047rs1799971） alleles were consistent with Hardy-Weinbergbalance test. The correlation analysis results showed that the proportion of genotype GG and AG in CYP3A5*3 （058rs776746， 163.com A＞G） and genotype AA and AG in OPRM1 （047rs1799971， A＞G） of patients was significantly higher in test group than that in the control group （P＜0.05）. Multivariate Logistic regression analysis showed that medication duration， CYP3A5*3 and OPRM1 gene polymorphism could be used as predictors of opioid- induced constipation in patients （P＜0.05）. The ROC curve analysis results showed that the areas under the ROC curves for medication duration and CYP3A5*3， OPRM1 gene polymorphism were 0.648， 0.640 and 0.670， respectively， with the optimal cutoff values of 124.0， 0.5 and 0.5， respectively. CONCLUSIONS Genotype GG and AG in CYP3A5*3 （058rs776746，A＞G） and genotype AA and AG in OPRM1 （047rs1799971，A＞G） are associated with opioid-induced constipation， which are expected to become clinical predictors of opioid-induced constipation， and more attention should be paid to the occurrence of constipation in patients who have been taking opioids for a long time.

Fetal electrocardiogram (ECG) signals provide important clinical information for early diagnosis and intervention of fetal abnormalities. In this paper, we propose a new method for fetal ECG signal extraction and analysis. Firstly, an improved fast independent component analysis method and singular value decomposition algorithm are combined to extract high-quality fetal ECG signals and solve the waveform missing problem. Secondly, a novel convolutional neural network model is applied to identify the QRS complex waves of fetal ECG signals and effectively solve the waveform overlap problem. Finally, high quality extraction of fetal ECG signals and intelligent recognition of fetal QRS complex waves are achieved. The method proposed in this paper was validated with the data from the PhysioNet computing in cardiology challenge 2013 database of the Complex Physiological Signals Research Resource Network. The results show that the average sensitivity and positive prediction values of the extraction algorithm are 98.21% and 99.52%, respectively, and the average sensitivity and positive prediction values of the QRS complex waves recognition algorithm are 94.14% and 95.80%, respectively, which are better than those of other research results. In conclusion, the algorithm and model proposed in this paper have some practical significance and may provide a theoretical basis for clinical medical decision making in the future.
