OBJECTIVES: To investigate the synergistic mechanism of the traditional Chinese medicine Rosa laevigata Michx. (RLM) for treatment of pulmonary arterial hypertension (PAH). METHODS: Network pharmacological analysis was carried out to screen the active ingredients of RLM and PAH disease targets and construct the "component-target-disease" interaction network, followed by gene enrichment analysis and molecular docking studies. In the cell experiments, primary cultures of rat pulmonary arterial smooth muscle cells were exposed to hypoxia for 24 h and treated with solvent or 100, 200 and 300 mg/mL RLM, and the changes in cell proliferation were detected using Western blotting for PCNA and immunofluorescence staining. In the animal experiment, male SD rats were randomized into 5 control group, monocrotaline (MCT) solvent group, and MCT with RLM (100, 200 and 300 mg/mL) treatment groups. HE staining and immunofluorescence staining were used to observe histopathological changes in the pulmonary blood vessels of the rats. RESULTS: Seven core active ingredients (including β-sitosterol and kaempferol) in RLM and 39 key disease targets were identified, and molecular docking showed that SRC was a high-affinity target. KEGG enrichment analysis showed that the differential genes were significantly enriched in calcium signaling and PI3K-AKT pathways. In rat pulmonary arterial smooth muscle cells, hypoxic exposure significantly up-regulated cellular expression of PCNA and phosphorylation levels of Src and AKT1, which were obviously lowered by RLM treatment. In RLM-treated rat models, the mean pulmonary artery pressure and right ventricular hypertrophy index (Fulton index) were significantly reduced, the tricuspid annular plane systolic excursion (TAPSE) was improved, and pulmonary vascular wall thickening and fibrosis were obviously ameliorated. CONCLUSIONS RLM inhibits pulmonary arterial smooth muscle cell proliferation in rat models of hypertension possibly by regulating the Src-AKT1 axis, suggesting the potential of RLM as a new natural drug for treatment of pulmonary hypertension.

Follicular lymphoma(FL)is a type of non-Hodgkin's lymphoma,and its treatment options face many challenges.This paper discusses the pathogenesis and treatment of FL based on the clear-turbid theory in traditional Chinese medicine(TCM)."The clear and the turbid being related,and the rise and fall of qi being disorderly"is the basic pathogenesis of FL.As the disease progres-ses,"evil qi being blocked inside,and turbid evil harming the clear"aggravates,and finally"evil qi is strong and the disease progres-ses,and evil poison is generated inside".Based on this theory,the method of raising the clear and lowering the turbid and the method of dispersing the clear and removing the turbid are proposed to treat FL.The emphasis of raising the clear and lowering the turbid is to take raising and lowering as the key,movement and stillness as the pivot,and to treat the middle jiao;the emphasis of dispersing the clear and removing the turbid is to clear the triple jiao,warm the yang and invigorate the qi,and harmonize the spleen and kidney.Ca-ses are attached to illustrate,providing new ideas for the TCM treatment of FL.

Varicocele is a common disease of the male reproductive system, and the pampiniform plexus in the spermatic cord manifests abnormal dilatation, extension, and circuity, which is a vasculopathy. In this article, we believe that the relevance of the essence chamber collaterals to the spermatic vein in terms of anatomical morphology and physiological function is high and that when pathogenic qi invades the essence chamber, the qi and collaterals of the essence chamber are out of harmony, the fluid collaterals are impassable, and the blood collaterals are obstrcuted, and the essence chamber collaterals are blockaded with several pathological products, and even intermingled phlegm and blood stasis in the blood collaterals and form vascular clusters, resulting in the formation and development of varicocele. Based on this, this article proposes the core treatment principle of healing, harmonizing, activating, and dredging the collaterals, with the basic treatment method of nourishing qi and harmonizing collaterals, activating blood collaterals, and dredging blood stasis to, respectively treat degree Ⅰ, Ⅱ, and Ⅲ varicocele, aiming to prevent the change of the varicocele, dredge the curvature of the varicocele, and dissipate the knots of the varicocele. The proposal of essence chamber collaterals is of great significance to understanding the common law and pathological aspects of the occurrence and development of essence collateral and vascular lesions from the perspective of integrated traditional Chinese and Western medicine.

Based on the pathogenesis of erectile dysfunction (ED) from the meridian-zangfu relationship and the "brain-heart-kidney-essence chamber" axis, it proposes that dysfunction of the "brain-heart-kidney-essence chamber" axis is closely related to the occurrence of ED. Among these, brain-heart disharmony is the key pathogenic factor, kidney deficiency and essence depletion constitute an important basis, and essence chamber stasis is a critical mechanism. The treatment approach emphasizes harmonizing the brain and heart, regulating the mind, tonifying the kidney and replenishing qi, unblocking qi and blood to harmonize the essence chamber. The primary acupoints include Baihui (GV20)-Neiguan (PC6)-Shenmen (HT7), Taixi (KI3)-Guanyuan (CV4)-Sanyinjiao (SP6), and Zhongji (CV3)-Dahe (KI12)-Gongsun (SP4), with additional acupoints selected based on syndrome differentiation. This approach aims to restore the clarity of the brain and heart, replenish kidney qi, and unblock the essence chamber, thereby facilitating the restoration of normal functions of the brain, heart, kidney, and essence chamber, and alleviating ED symptoms and improving overall clinical efficacy.

Objective To establish a technical system for allogeneic kidney transplantation surgery in pigs using the Banna miniature pig inbred strain,and to evaluate it through routine blood tests,liver and kidney function tests,thus providing reference data for the preparation of allogeneic kidney transplantation models.Methods A total of 4 cases of allogeneic kidney transplantation surgeries were performed,including 1 case of single kidney transplantation in a healthy pig,2 cases of kidney transplantation after unilateral nephrectomy,and 1 case of kidney transplantation after bilateral nephrectomy.Before kidney transplantation,cross-matching and complement-dependent cytotoxicity(CDC)tests were used for matching between donor and recipient pigs.After kidney transplantation,peripheral blood samples were regularly collected from pigs for routine blood tests,liver function tests,and kidney function tests,and color Doppler ultrasound technology was used to detect blood supply to the transplanted kidneys.After reaching the experimental endpoint,both kidneys of pig DR1 and the left kidney of pig DR3 were collected and hematoxylin-eosin(HE)staining was performed to evaluate pathological changes in the transplanted kidneys.Results Recipient pigs DR1 and DR3 died at 17 days and 30 days after surgery respectively,while recipient pigs R and DR2 remained in good condition during the 30-day observation period.The results of liver and kidney function test showed that in pig DR1,alanine aminotransferase(ALT)levels increased on postoperative day 1(＞1 000 U/L),peaked on postoperative day 7(1 300 U/L),and aspartate aminotransferase(AST)levels peaked on postoperative day 1(＞3 000 U/L).On postoperative day 17,ALT and AST levels remained high(ALT,500 U/L;AST,700 U/L).In pigs R,DR2,and DR3,ALT and AST levels returned to normal around day 17.Serum creatinine(Crea)levels in pig R remained stable without postoperative increase.Crea levels in pigs DR1 and DR2 showed transient elevation on postoperative day 1,then gradually returned to normal(＜100 μmol/L).Crea levels in pig DR3 remained below 500 μmol/L from postoperative days 2-10,but increased between days 11-28,reaching up to 1 500 μmol/L,indicating gradual loss of kidney function.Ultrasound results showed that the preoperative resistive index(RI)of recipient pig R was 0.91.On postoperative day 24,renal cortex and medulla showed abundant blood flow signals with RI value of 0.88,which was close to the pre-transplantation RI value.For pig DR2,the RI value on postoperative day 17 was 0.89,with poor renal cortex blood flow and relatively good renal medulla blood flow.In pig DR1 on postoperative day 17,no blood flow signals were detected in the transplanted kidney.HE staining results showed that the non-transplanted healthy right kidney of pig DR1 had normal structure,while the transplanted left kidney showed blurred glomerular structure and nuclear dissolution,indicating that the left kidney had lost function before removal.In the transplanted left kidney of pig DR3,large numbers of red blood cells and lymphocyte infiltration were observed in glomeruli and renal tubules,indicating possible coagulation dysfunction and rejection reactions after kidney transplantation.Conclusion Banna miniature pig inbred strain is used as experimental animals to perform four cases of allogeneic pig-to-pig kidney transplantation.The physiological parameters of the recipient pig and the function of the transplanted kidney are monitored after surgery using routine blood tests,liver and kidney function tests,color Doppler ultrasound,and pathological examinations.The allogeneic pig-to-pig kidney transplantation technical system established in the study can provide a foundation for clinicians to conduct kidney transplantation surgeries.

Male infertility,a common condition in andrology,falls under the category of"no son"in traditional Chinese medicine(TCM).Unhealthy eating habits and excessive sexual activity,prevalent due to improved living standards,have contributed to the increasing incidence of male infertility.YE Tianshi proposed the theory of"maintaining with the sweet and restoring the body fluids",which emphasizes the importance of ample body fluid for the nourishment of the male essence chamber.Sufficient body fluid is crucial for normal sperm generation.In TCM,the primary pathogenesis of male infertility involves the loss of body fluids and insufficiency of yin essence.Sweet Chinese herbal medicinal is recommended as it nourishes yin,enriches essence,and replenishes male reproductive essence without producing phlegm and dampness.Therefore,when treating male infertility,attention should be given to the use of sweet Chinese herbal medicinal,adhering to the principle of"abundant body fluids nourish kidney yin,and abundant kidney yin supports semen production".Therapies such as purging fire to preserve body fluids with Zengye Decoction,nourishing yin to enrich essence with Guilu Erxian Decoction,benefiting qi to promote fluid production with Buzhong Yiqi Decoction,and warming yang and transporting fluids with Xianfu Shezi Decoction should be considered.Medication and dosage adjustments should be made based on the specific etiology,pathology,and related symptoms to improve the quality of male sperm and enhance the chances of conception.
