The lymphatic system, as well as pathological changes of the lymphatic system, underlies the progress of an array of diseases and conditions, including cancer, inflammation and autoimmune disorders, infectious diseases and metabolic syndrome. A variety of biological targets in the lymphatic system can be employed to modulate these high-burden diseases, and the pharmacokinetics and drug delivery strategies in the context of lymphatics are of critical importance to optimise drug exposure to lymphatic-related targets. As such, research and drug development in this field has gained increasing attention in recent years. This article aims to provide an overview of pharmaceutical research with a focus on the lymphatic system and therapeutic targets within the lymphatics, followed by lymphatic drug delivery approaches, which may be of interest for researchers in academia, pharmaceutical industry and regulatory sciences.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

ObjectiveTo explain the pharmacodynamic substances of Aurantii Fructus flavonoids that exert anti-inflammatory and analgesic effects using a structure-activity omics approach. MethodOn the basis of the previous in vitro pharmacological screening conducted by the research team， an in vivo pharmacological study of Aurantii Fructus flavonoids was carried out. Core targets of the anti-inflammatory and analgesic active components of flavonoids of Aurantii Fructus were identified using various network databases， including the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， the Online Mendelian Inheritance in Man （OMIM）， and the Search Tool for the Retrieval of Interacting Genes/Proteins （STRING）. Computer-aided virtual screening technology was used to dock different types of Aurantii Fructus flavonoids with core targets. The key core targets with high binding activity were selected based on the comprehensive scores of each target and the active structures. Using these targets as bridges， the structures of one or more types of chemical components in Aurantii Fructus were closely linked to pharmacological effects. The structure-activity relationship between the clear pharmacodynamic compounds and their effects was explored through the binding patterns of various structures with pharmacodynamic targets. ResultAurantii Fructus flavonoids demonstrated significant anti-inflammatory and analgesic effects on dextran sulfate sodium （DSS）-induced colitis in mice， which could improve symptoms and significantly reduce the levels of inflammatory factors interleukin-6 （IL-6） and interleukin-1β （IL-1β）（P<0.05）. Twelve active components of Aurantii Fructus flavonoids were identified and categorized into nine dihydroflavonoids and three flavonoids based on their structures of the parent nuclei. Through Venn analysis， 167 anti-inflammatory and analgesic targets for Aurantii Fructus were identified. Based on degree value and molecular docking comprehensive scores， prostaglandin-endoperoxide synthase 2（PTGS2） and mitogen-activated protein kinase 3（MAPK3） were selected for further structural analysis. Structural analysis revealed that components containing glycoside structures exhibited higher binding activity with anti-inflammatory and analgesic targets. ConclusionThis study utilized a structure-activity omics approach based on in vivo pharmacodynamic experiments to analyze the material basis of the anti-inflammatory and analgesic effects of Aurantii Fructus flavonoids. The structure-activity omics approach provides new ideas and methods for elucidating the pharmacodynamic substances of Chinese medicine.

ObjectiveTo elucidate the active compounds for the anti-inflammatory and analgesic effects of Paeoniae Radix Alba from structure-activity omics. MethodOn the basis of the previous in vitro efficacy study by our research group， a mouse model of foot swelling was induced by methyl aldehyde and used to study the anti-inflammatory and analgesic effects of total glycosides of Paeoniae Radix Alba in vivo. The core targets of the active compounds for the anti-inflammatory and analgesic effects of Paeoniae Radix Alba were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， Online Mendelian Inheritance in Man （OMIM）， and Search Tool for Recurring Instances of Neighbouring Genes （STRING）. Molecular docking was conducted for the total glucosides of Paeoniae Radix Alba with the core targets， and the key core targets with high binding affinity were screened out according to the comprehensive score of each target and active structure. The structure-activity relationship was analyzed with targets as a bridge through the combination of compound structures and pharmacological effects. ResultThe total glucosides of Paeoniae Radix Alba had good anti-inflammatory and analgesic effects in vivo. The core targets of 23 active components of Paeoniae Radix Alba were epidermal growth factor receptor （EGFR）， signal transducer and activator of transcription 3 （STAT3）， vascular endothelial growth factor A （VEGFA）， cellular tumor antigen p53 （TP53）， and proto-oncogene transcription factor （JUN）. According to the structure of the parent nucleus， there were 16 pinane monoterpene glycosides， 4 pinene monoterpene glycosides， 2 monoterpene lactone glycosides， and 1 monoterpene ketone. The key core targets screened out by molecular docking were EGFR and STAT3. The structure-activity analysis of the active compound structures and the key core targets showed that the introduction of ketone group and benzene ring group on the parent nucleus affected the binding activity. ConclusionThis study analyzed the material basis for the anti-inflammatory and analgesic effects of total glycosides of Paeoniae Radix Alba from structure-activity omics， providing new ideas and methods for revealing the pharmacodynamic substances in traditional Chinese medicine.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the effects of calorie-restricted diet(CRD)combined with intesti-nal micro-ecological preparation on the clinical outcomes of overweight/obese infertile patients undergoing fresh embryo transfer cycle.Methods A total of 197 cases of fresh embryo transfer assisted by in vitro fertili-zation(IVF)/intracytoplasmic sperm injection(ICSI)-embryo transfer(ET)in the hospital from January,2019 to December,2021 were selected as the research objects,and were divided into the overweight interven-tion group(n=46),the overweight control group(n=85)and the obesity intervention group(n=85)accord-ing to the body mass index(BMI)and whether they accepted CRD intervention or not.Results Compared to before the intervention,the overweight intervention group had significantly lower body mass[(63.59±4.90)kg vs.(67.47±5.10)kg],BMI[(25.74±1.26)kg/m2 vs.(26.58±0.75)kg/m2],body fat percentage[(36.51±3.76)％vs.(39.21±4.26)％],waist to hip ratio(0.88±0.04 vs.0.91±0.04),visceral fat grade(10.80±2.45 vs.12.63±2.60),and basal metabolic rate[(1 235.98±74.32)kcal vs.(1 254.63±77.23)kcal],P＜0.05;The body mass[(71.79±9.78)kg vs.(77.18±9.62)kg],BMI[(29.04±2.96)kg/m2 vs.(31.21±2.64)kg/m2],body fat percentage[(40.47±4.77)％vs.(43.97±3.81)％],waist to hip ratio(0.92±0.05 vs.0.96±0.06),and visceral fat grade(14.00±3.74 vs.16.59±3.15)of the obesity interven-tion group were significantly reduced(P＜0.05).Compared with the overweight control group,the number of transplanted embryos(1.85±0.36 vs.1.96±0.19)in the overweight intervention group was less(P＜0.05),while the number of live births(0.61±0.37 vs.0.56±0.36)was more,the live birth rate(43.48％vs.40.00％)was higher,but there was no statistically significant difference(P＞0.05).The clinical preg-nancy rate and live birth rate in the obesity intervention group were higher than those in the control group(72.41％vs.51.35％and 58.62％vs.35.14％),with no statistical significance,but with a strong statistical significance(P＞0.05).Conclusion CRD combined with intestinal micro-ecological preparation can signifi-cantly reduce the body mass and body fat of overweight/obese infertile patients,may help improve the success rate of assisted reproduction in obese infertile patients.

Objective:To investigate the association of serum fibroblast growth factor 23(FGF23) level with insulin resistance(IR) and sex hormone levels in patients with polycystic ovary syndrome(PCOS).Methods:A retrospective study was performed in eighty-seven patients with PCOS, fifty-seven patients with simple IR, and sixty-one healthy women who were admitted to Affiliated Hospital of Zunyi Medical University during October 2021 and November 2022. According to the homeostasis model assessment-IR index, all subjects were divided into normal control group( n=61), IR group( n=57), PCOS without IR group(PCOS group, n=15), and PCOS+ IR group( n=72). The levels of serum FGF23, adiponectin, and sex hormones in all groups were compared, and their correlations with glucose and lipid metabolism indicators were analyzed. Results:The FGF23 level was significantly elevated in the IR group, while markedly reduced in the PCOS group and PCOS+ IR group, with the PCOS group showing a significantly lower concentration. The adiponectin levels were significantly decreased in the IR group, PCOS group, and PCOS+ IR group(all P<0.05). The correlation analysis showed that FGF23 level was positively correlated with adiponectin and sex hormone binding globulin, and negatively correlated with luteinizing hormone, luteinizing hormone/follicle stimulating hormone, and free testosterone index(all P<0.05). Logistic regression results indicated that both FGF23 and adiponectin could be used as good indicators for the diagnosis of PCOS and PCOS with IR(all P<0.05). Conclusion:FGF23 is closely related to IR and androgen as well, and under certain conditions, it can reflect the severity of IR and hyperandrogenemia in PCOS patients. The cutoff value of FGF23 obtained in this study can provide a good reference for the diagnosis of PCOS diseases.

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

ObjectiveThe hygroscopic properties of Mume Flos decoction pieces were studied from the perspectives of macroscopic［water activity（A_w）］ and microscopic（water molecular mobility）， which provided a theoretical basis for the determination of the safe storage moisture content. MethodAdsorption isotherm of Mume Flos decoction pieces was obtained by static weighing method， and seven common hygroscopic models were fitted and estimated. The best model was selected according to the principle that determination coefficient（R²） was closer to 1， residual sum of squares（RSS） was closer to 0 and Akaike information criterion（AIC） was smaller. According to the optimal model， the absolute and relative safe moisture contents of Mume Flos decoction pieces at 25， 35， 45 ℃ was calculated. Low-field nuclear magnetic resonance（LF-NMR） was used to measure the water molecular mobility in the hygroscopic process of Mume Flos decoction pieces. ResultThe best model to describe the adsorption isotherm of Mume Flos decoction pieces was the Peleg model. According to the model expression， the absolute safe moisture contents of Mume Flos decoction pieces at 25， 35， 45 ℃ were 9.59%， 7.96% and 7.68%， and the relative safe moisture contents were 13.05%， 11.99%， 11.77%， respectively. Mume Flos decoction pieces all contained two water states during the process of hygroscopic absorption at different temperatures， namely bound water T₂₁ and free water T₂₂. During the process of hygroscopic absorption， bound water had the largest increase in peak area. The sum of peak areas of the bound water and free water had a good linear relationship with the moisture contents， and the R² were 0.959 9， 0.911 8 and 0.974 7 at 25， 35， 45 ℃， respectively. When A_w<0.57， T₂₁ did not change， and the water molecular mobility remained unchanged. When A_w>0.57， T₂₁ showed an increasing trend， and the water molecular mobility increased. The moisture contents of Mume Flos decoction pieces were 8.44%， 6.81% and 6.25% when the water molecular mobility increased at 25， 35， 45 ℃， respectively. ConclusionCombined with the theory of water activity and water molecular mobility， 6.25% is recommended as the safe storage moisture content of Mume Flos decoction pieces， this study can provide reference for determining the safe storage moisture content of other decoction pieces.
