This article systematically reviews and verifies the name， origin， production area， quality evaluation， harvesting， processing and other aspects of Cynanchi Atrati Radix et Rhizoma（CARR） by consulting relevant ancient and modern literature， in order to provide a basis for the development and utilization of famous classical formulas containing this herb. Through textual research， Baiwei has been the official name for CARR， though it also bears alternative names such as Chuncao， Popo Zhenxianbao， Longdan Baiwei. The mainstream base is the roots and rhizomes of Cynanchum atratum. Historical records indicate primary producing areas include Shandong， Anhui， Jiangsu， Shaanxi and Shanxi. Since the late Ming dynasty， varieties from Juxian， Yishui and Rizhao in Shandong have been highly regarded as authentic， commonly known as eastern Baiwei. Since modern times， its quality has been summarized as fine， slender， and straight fibrous roots， pale yellow exterior， whiter interior， and dryness with easy breakability are considered superior. The harvesting time before the Song dynasty was on the third day of the third lunar month， but after the Song dynasty， harvesting was possible in both spring and autumn. The initial processing methods of CARR in ancient times included drying in the shade， removing Lu（the little rhizomes which are on tap of roots）， and removing mustaches， modern methods involve washing and sun-drying. During the Northern and Southern dynasties， processing methods included steaming. In the Song dynasty， drying and light stir-frying were predominant， while wine washing emerged in the Ming dynasty. Modern practices primarily involve using raw， stir-frying or honey processing. Regarding the medicinal properties of CARR， both ancient and modern texts agree it has a bitter and salty taste and is non-toxic. Records prior to the Qing dynasty predominantly describe its nature as extremely cold， while mainstream herbal texts after the Qing dynasty generally characterize it as cold. Before the Ming dynasty， there were no records of its meridian tropism. It was not until the Qing dynasty that it was recorded in the lung meridian. Modern records mainly refer to the stomach， liver， and kidney meridians. Throughout history， its main functions have been to clear heat， diuresis， nourish Yin， and replenish essence， primarily treating Yin deficiency and fever syndrome. Based on the research results， it is suggested that when developing famous classical formulas containing CARR， the dried roots and rhizomes of C. atratum can be selected as its medicinal source. If there are no specific processing requirements， raw products can be selected as medicine. If the processing requirements are specified， corresponding processed products can be selected as medicine according to the original formula requirements.

This article systematically analyzes the historical evolution of the name， origin， medicinal parts， producing area， harvesting and processing， nature， flavor and efficacy of Piperis Longi Fructus by referring to the materia medica， medical books， and prescription books of past dynasties， combined with the relevant modern literature， in order to provide a basis for the development and utilization of famous classical formulas containing this herb. According to the herbal textual research， the name of Piper longum first appeared in Nanfang Caomuzhuang， and it also has other aliases such as Biboli， Halou， and Hujiaohua. Historically， the origin of Piperis Longi Fructus has been P. longum of the Piperaceae family. In ancient times， both the fruit and root were used as medicine， and since the Republic of China， the fruit has been mainly used as medicine. The medicinal part is the dried， nearly ripe or ripe fruit spikes. Piperis Longi Fructus is native to India and has been introduced into China since the Tang dynasty. In the Ming dynasty， Bencao Pinhui Jingyao clearly stated that the genuine producing area was "Duanzhou"， present-day Zhaoqing in Guangdong province. Nowadays， it is planted in Guangdong， Guangxi， Hainan， Yunnan and other regions. Historically and currently， harvesting occurs in autumn. The ancient processing method uniformly involved removing the stems， soaking in the sourest vinegar overnight， baking， and scraping off the peels and grains with a knife until clean. In modern times， impurities are removed， and it is dried in the sun and crushed when used. The properties， functions and applications of P. longum are basically the same in ancient and modern times. It tastes pungent， is warm in nature， and non-toxic. It has the effects of warming the middle-jiao to dispel cold， lowering Qi and relieving pain， and is used for cold pain in the epigastrium and abdomen， vomiting， diarrhea， chest pain， headache， and toothache. Based on the research results， it is recommended that when developing famous classical formulas containing Piperis Longi Fructus， the dried nearly ripe or ripe fruit spikes of P. longum should be used. If there are no clear processing requirements， it is recommended to use the raw products for medicinal use， and the specific processing methods can refer to the relevant requirements under Piperis Longi Fructus in the 2025 edition of the Pharmacopoeia of the People's Republic of China. If processing requirements such as soaking in vinegar and peeling are clearly specified， it is recommended to follow the ancient methods.

Objective:To investigate the expression of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues and analyze their expression levels in relation to clinical features and prognosis. Methods:From January 1, 2019, to December 31, 2019, 69 cases of nasopharyngeal carcinoma tissues and adjacent non-cancerous tissues were collected from patients treated at Yunnan Cancer Hospital. Immunohistochemistry was employed to detect the expression of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues. The Kaplan-Meier method was used to predict survival time, and the clinicopathological features were evaluated using the log-Rank test. Results:The positive expression rates of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues were 87.0% and 84.5%, respectively. Compared to adjacent normal tissues, the expression levels of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues were significantly increased （P<0.05）. Furthermore, the expression of NFAT5 and IGF1R was positively correlated with T stage, N stage, skull base invasion, and cranial nerve palsy （P<0.05）. The overexpression of NFAT5 and IGF1R significantly affected the survival rate of patients with nasopharyngeal carcinoma and was negatively correlated with prognosis （P<0.05）. Conclusion:In nasopharyngeal carcinoma tissues, overexpression of NFAT5 and IGF1R is observed, which is closely linked to clinical features and patient outcomes. These markers may serve as valuable indicators for predicting the prognosis of nasopharyngeal carcinoma.

Objective:Retrospective analysis of the correlation between clinicopathologic features and related indexes and prognosis in patients with recurrent nasopharyngeal carcinoma. Methods:One hundred and eight nasopharyngeal cancer（NPC） patients with post-treatment recurrence in Yunnan Cancer Hospital from January 2013 to January 2018 were collected, and the survival time was estimated by Kaplan-Meier method, and clinicopathological characteristics were analyzed by log-rank test; risk factors and prognosis were analyzed by Cox proportional risk model for single-factor and multifactorial analysis. A P-value <0.05 was considered statistically significant. Results:The median survival of all patients was 54 months, with a 3-year survival rate of 80.2% and a 5-year survival rate of 39.8%. The 5-year overall survival rate was 50.2% for patients >46 years old and 27.9% for patients ≤46 years old（P<0.05）, a statistically significant difference. Univariate analysis showed that overall survival was associated with age, chemotherapy regimen, EBV early antigen IgA, plasma D-dimer, glycan antigen-125, γ-interferon, α-tumor necrosis factor, IL-10, and IL-4（P<0.05）. Multifactorial analysis revealed that age, chemotherapy regimen, EBV early antigen IgA, plasma D-dimer, glycan antigen-125, and interleukin 10 were independent influences on the prognosis of recurrent nasopharyngeal carcinoma（P<0.05）. Conclusion:Differences in chemotherapy regimens affect the prognosis of recurrent nasopharyngeal carcinoma. Elevated plasma D-dimer, glycan antigen 125, and interleukin 10 levels affect the overall survival of recurrent nasopharyngeal carcinoma, which may be a valid independent prognostic factor, and are expected to provide new biomarkers for nasopharyngeal carcinoma in the clinic.

Objective To investigate the effects of modified Banxia Baizhu Tianma Decoction(BBTD)on blood pressure and lipid metabolism in patients with metabolic hypertension and dyslipidemia of phlegm-damp obstruction syndrome,guided by Professor Tong Xiaolin's"state-target differentiation and treatment"theory.Methods Sixty eligible patients treated at Chongqing Beibei Hospital of Traditional Chinese Medicine from February 2024 to February 2025 were randomly assigned to treatment group(n=30,receiving conventional therapy plus modified BBTD)and control group(n=30,conventional therapy alone)for 4 weeks.The changes in blood pressure,lipid profiles,body mass index(BMI),fasting blood glucose(FBG),serum uric acid(SUA)were observed,and the antihypertensive efficacy and traditional Chinese medicine(TCM)syndrome efficacy were evaluated.Results(1)Regarding participant dropout,during the study,2 cases in the treatment group were lost to follow-up,while no dropouts occurred in the control group.Ultimately,58 patients were included in the efficacy analysis(28 in the treatment group,30 in the control group).(2)In terms of antihypertensive efficacy,after 4 weeks of treatment,the total effective rate was 92.86％(26/28)in the treatment group versus 36.67％(11/30)in the control group.The intergroup comparison(by chi-square test)demonstrated significantly superior antihypertensive efficacy in the treatment group(P＜0.05).(3)For TCM syndrome efficacy,the marked improvement rate and total effective rate in the treatment group were 60.71％(17/28)and 92.86％(26/28)respectively,compared to 0.00％(0/30)and 33.33％(10/30)in the control group.The treatment group showed significantly better outcomes in marked improvement rate(by chi-square test),total effective rate(by chi-square test),and overall efficacy(by rank-sum test)(all P＜0.05).(4)Regarding blood pressure,post-treatment systolic blood pressure(SBP)and diastolic blood pressure(DBP)were significantly decreased in the treatment group(P＜0.05)but remained unchanged in the control group(P＞0.05).The treatment group exhibited significantly greater reductions in both SBP and DBP compared to controls(P＜0.05).(5)For lipid profiles,the treatment group showed significant post-treatment reductions in total cholesterol(TC),triglycerides(TG),and low-density lipoprotein cholesterol(LDL-C)(P＜0.05).The control group demonstrated increased TG(P＜0.05),with nonsignificant decreases in TC and LDL-C,and a slight increase of HDL-C(P＞0.05).The treatment group achieved significantly greater TC and TG reductions versus controls(P＜0.05).(6)The treatment group showed decreased BMI,fasting glucose,and serum uric acid(P＜0.05),whereas the control group had unchanged BMI and fasting glucose(P＞0.05)but increased uric acid(P＜0.05).The treatment group's reductions in fasting glucose and uric acid were significantly superior to those of control group(P＜0.05).Conclusion State-target-guided modified BBTD effectively treats metabolic hypertension with dyslipidemia of phlegm-damp obstruction syndrome,demonstrating comprehensive metabolic benefits beyond blood pressure control.

ObjectiveExploring the role of microRNA126 （miRNA126） in chronic kidney disease combined with atherosclerosis （CKD AS） by regulating the phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway and the mechanism of Shenshuai Xiezhuo decoction in the intervention of CKD AS rats with 5/6 nephrectomy combined with high-fat feeding. MethodA total of 60 SD rats were randomly divided into sham operation group， model group， losartan group， and low， medium， and high dose groups of Shenshuai Xiezhuo decoction. The CKD AS rat model was established by 5/6 nephrectomy combined with high-fat feeding for 10 weeks. The low， medium， and high dose groups （6.0， 12.0， 24.0 g·kg^-1·d^-1） of Shenshuai Xiezhuo decoction and the losartan group （20 mg·kg^-1·d^-1） were gavaged， and the corresponding intervention was carried out for eight weeks. Then， the rats were killed， and samples were collected for corresponding detection. Fully automated biochemical analyzers were used to detect kidney function and blood lipids in rats： blood creatinine （SCr）， blood urea nitrogen （BUN）， total cholesterol （TC）， triglyceride （TG）， and low-density lipoprotein cholesterol （LDL-C） levels. Hematoxylin-eosin （HE） and Masson staining of aortic tissue and pathological observation under a light microscope were carried out， and autophagosomes and autophagy lysosomes were observed by transmission electron microscopy. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to determine the mRNA levels of miRNA126， PI3K， Akt， and mTOR in rats， and Western blot was used to determine the protein expression levels of phosphorylated （p）-PI3K， PI3K， p-Akt， Akt， p -mTOR， mTOR， benzyl chloride 1 （Beclin-1）， and microtubule-associated protein light chain 3Ⅱ/Ⅰ （LC3Ⅱ/LC3Ⅰ）. ResultCompared with the sham operation group， the serum SCr， BUN， TC， TG， and LDL-C in the model group were significantly increased （P<0.01）. Compared with the model group， the SCr， BUN， TC， TG， and LDL-C were decreased in the losartan group and low， medium， and high dose groups of Shenshuai Xiezhuo decoction （P<0.05）. Compared with the sham operation group， thickening plaques， infiltration of mononuclear macrophages， a small number of foam cells， disordered arrangement of smooth muscle fibers in the tunica media， and increased collagen fibers were observed in the model group， and the lesions in the losartan group and Shenshuai Xiezhuo decoction groups were alleviated compared with those in the model group. Compared with the model group， the number of autophagosomes and autophagy lysosomes increased in the medium and high dose groups of Shenshuai Xiezhuo decoction. Compared with the sham operation group， the expression of miRNA126 in the aortic tissue of the model group was significantly decreased （P<0.01）， and the mRNA expressions of PI3K， Akt， and mTOR were significantly increased （P<0.01）. Compared with the model group， the expression of miRNA126 in the aortic tissue of rats in high， medium， and low dose groups of Shenshuai Xiezhuo decoction and losartan group was significantly increased （P<0.01）， while the mRNA expressions of PI3K， Akt， and mTOR were significantly decreased （P<0.01）. Compared with the sham operation group， the protein expressions of p-PI3K， PI3K， p-Akt， Akt， p-mTOR， and mTOR in the model group were significantly increased （P<0.01）， while the protein levels of Beclin-1， LC3Ⅰ， and LC3Ⅱ were significantly decreased （P<0.01）. Compared with the model group， the protein expressions of p-PI3K， PI3K， p-Akt， Akt， p-mTOR， and mTOR in the losartan group and low， medium， and high dose groups of Shenshuai Xiezhuo decoction were decreased （P<0.05）， while the protein levels of Beclin-1 and LC3Ⅱ/LC3Ⅰ were increased （P<0.05）. ConclusionThe expression of miRNA126 is decreased in the aortic tissue of CKD AS rats， and the PI3K/Akt/mTOR pathway is activated to inhibit autophagy flux. Shenshuai Xiezhuo decoction regulates the PI3K/Akt/mTOR signaling pathway through miRNA126， restores the autophagy of aortic endothelial cells， protects the damage of CKD vessels， reduces the formation of As plaques， and slows the development of cardiovascular complications.

Objective:To explore the role of arginine metabolism in the inflammatory response to influenza A virus (FluA) infection.Methods:Eighteen-month-old mice were infected with FluA via nasal drip, with samples collected on the 6th day post-infection. The concentration of cytokines was determined by the Luminex multifactor assay, while the metabolites in bronchoalveolar lavage fluid (BALF) were analyzed using targeted metabolomic method. Correlation analysis was employed to examine the correlation between cytokines and metabolites. Macrophages were infected with FluA at a multiplicity of infection (MOI) of 1 and cultured with different concentrations of arginine for 24 h. The mRNA and protein expression levels of interleukin (IL)-1β, IL-6, tumor necrosis factor α (TNF-α) and IL-10 were detected by real time fluorescence quantitative RT-PCR (qRT-PCR) and Cytometric Bead Array (CBA).Results:In comparison to the control group, the levels of surfactant protein D (SP-D), TNF-α, monocyte chemotactic protein-1 (MCP-1), IL-1α, IL-6, IL-10, recombinant S100 calcium binding protein (S100) A9, interferon inducible protein 10 (IP-10), macrophage inflammatory protein-1α (MIP-1α), matrix metalloprotein-9 (MMP-9), and Complement Factor D in BALF of FluA infection exhibited a significant elevation. The concentrations of arginine, aspartate, citrulline, glutamic acid, ornithine, proline, creatine, and sarcosine in arginine metabolism were up-regulated, which was correlated with most of elevated cytokine levels. The supplementation of arginine after FluA infection significantly decreased the levels of IL-1β, IL-6, and TNF-α, but increased the level of IL-10 in macrophages.Conclusions:Arginine reduces the inflammatory response induced by FluA infection in macrophages, suggesting that it may be a potential intervention target for severe pulmonary inflammation following FluA infection.

Diagnosis and treatment of hepatitis B virus (HBV) infection in children is a hotspot of concern in the field of HBV infection. This article reviews the current status and progress of antiviral treatment for children with chronic hepatitis B (CHB) in recent years, focusing on clinical issues such as the choice of antiviral treatment regimen for children with HBeAg-positive CHB (immune-clearance phase), the necessity of antiviral treatment for children with HBeAg-positive HBV infection (immune-tolerance phase), and the timing of antiviral treatment for infants with HBV infection, to explore the relevant factors that may affect the clinical cure of children with CHB. At the same time, based on the expert consensus on the prevention and treatment of children with CHB just published by Chinese experts, relevant diagnosis and treatment plans are proposed, with a view to providing reference and basis for clinical decision-making in children with CHB.

Objective:To investigate the status of corneal epithelial remodeling and changes in corneal aberration after femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) and FS-LASIK combined with corneal collagen cross-linking (FS-LASIK Xtra), and to analyze the relationship between corneal epithelial thickness (CET) and corneal aberration.Methods:A cohort study was conducted.A total of 172 patients (172 eyes) who underwent FS-LASIK at Yinhai Eye Hospital of Chengdu University of Traditional Chinese Medicine were enrolled from June 2021 to February 2022.The 172 eyes were divided into FS-LASIK group (94 eyes) and FS-LASIK Xtra group (78 eyes) according to the surgical procedure, with a total follow-up of 6 months.The cornea was divided into a central 2-mm ring and a ring of 2-5 mm centered on the central cornea.CET at 9 regions in the central 0-5 mm area was measured by OCT before and at 1, 3 and 6 months after surgery, and the corneal higher-order aberration (HOA) was measured by the iTrace visual function analyzer.The main outcomes were the increase in CET (ΔCET), and corneal HOA at 6 months after surgery.The relationship between central corneal ΔCET and corneal aberration was analyzed.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Yinhai Eye Hospital of Chengdu University of Traditional Chinese Medicine (No.2021yh-009). Written informed consent was obtained from each subject.Results:At 1, 3 and 6 months after surgery, the central, superior, superior nasal, nasal, inferior nasal, inferior, inferior temporal, temporal and superior temporal ΔCET were significantly smaller in FS-LASIK Xtra group than in FS-LASIK group (all at P<0.05). In FS-LASIK Xtra group, 6-month postoperative central, superior, superior nasal, inferior and inferior temporal ΔCET were significantly larger than those at 1 month after surgery, and 3- and 6-month postoperative temporal ΔCET were significantly larger than that at 1 month after surgery, and 6-month postoperative superior temporal ΔCET was significantly larger than those at 1 and 3 months after surgery (all at P<0.05). In FS-LASIK group, 3- and 6-month postoperative central, superior, inferior and inferior temporal ΔCET were significantly larger than those at 1 month after surgery, and 6-month postoperative superior nasal ΔCET was significantly larger than that at 3 months after surgery, and 6-month postoperative nasal, inferior nasal, temporal, superior temporal ΔCET were significantly larger than those at 1 and 3 months after surgery (all at P<0.05). There was no significant difference in vertical trefoil, vertical and horizontal coma changes at different time points after surgery between both groups (vertical trefoil: χ2group=4.27, P=0.118; χ2time=0.01, P>0.05.vertical coma: χ2group=5.74, P=0.057; χ2time=0.08, P=0.957.horizontal coma: χ2group=3.97, P=0.137; χ2time=0.51, P=0.773). The tilted trefoil changes at 1, 3 and 6 months after surgery of FS-LASIK Xtra group were significantly larger than those of FS-LASIK group (all at P<0.05). The 6-month spherical aberration change in FS-LASIK Xtra group was significantly higher than that at 1 month after surgery, and the 6-month spherical aberration change in FS-LASIK group was significantly higher than that at 1 and 3 months after surgery (all at P<0.05). The 6-month total HOA change in FS-LASIK group was significantly lower than that at 1 and 3 months after surgery (all at P<0.05). In FS-LASIK group, central corneal ΔCET was weakly positively correlated with spherical aberration at 1 and 6 months after surgery ( rs=0.257, P=0.008; rs=0.244, P=0.012), and was weakly positively correlated with total HOA ( rs=0.253, P=0.009; rs=0.279, P=0.004). Conclusions:The postoperative ΔCET after FS-LASIK Xtra is smaller than that after FS-LASIK, but the homogeneity of ΔCET in each region is similar between the two groups.The changes in corneal HOA after surgery are similar in both groups, and there is a certain association between the overall epithelial distribution and corneal aberration.
