Eucommia ulmoides， a plant belonging to Eucommiaceae， has a history of medical use for over two thousand years in China. The dried bark and leaves of this plant are usually used as medicinal materials. Due to the high safety in clinical application， E. ulmoides leaves were officially recognized for both medicinal and edible use by the food safety evaluation in 2019， providing a valuable resource for the development of food and health products. According to the traditional Chinese medicine theory， E. ulmoides has the effects of nourishing the liver and kidneys， strengthening sinews and bones， and calming fetus. Modern research has shown that different parts such as the bark， leaves， flowers， and seeds of E. ulmoides contain similar chemical components， including phenylpropanoids， terpenoids， flavonoids， phenolic acids， steroids， and polysaccharides. E. ulmoides exhibits diverse pharmacological activities such as lowering blood pressure and blood lipid and glucose levels， preventing osteoporosis and possesses anti-tumor， anti-bacterial， antiviral， anti-inflammatory， antioxidant， and hepatoprotective effects. Therefore， it holds great potential for the development of products with both medicinal and edible values. This review systematically summarizes the chemical constituents， pharmacological activities， and representative medicinal and edible products of different parts of E. ulmoides. It is expected to provide theoretical references for the clinical application of E. ulmoides and its active components and the development and utilization of the products with both medicinal and edible values. This review contributes to a deeper understanding of the medicinal properties of E. ulmoides and provides guidance for further exploration of its applications in the healthcare field. As a plant with both medicinal and edible values， E. ulmoides is expected to attract more attention in future research and contribute to human health.

Objective:To investigate the efficacy and safety of kidney sparing treatment based on Thulium laser ablation and systematic therapy in localized high-risk upper urinary tract urothelial carcinoma (UTUC).Methods:The data of 10 patients with UTUC who received combined treatment based on Thulium laser and systematic treatment from January 2020 to December 2021 in West China Hospital were retrospectively analysed. There were 5 males and 5 females with a median age of 76 (range 52 to 87)years old. Three cases were renal pelvis tumor and 7 cases were ureter tumor including 5 cases in lower ureter and 2 cases in upper and middle ureter. Five cases were with positive urine cytology and 6 cases were with hydronephrosis. One case was muscular invasion UTUC confirmed by biopsy(cT 2+), 7 cases were high-grade invasive urothelial carcinoma (cT 1+), and 2 cases were high-grade papillary urothelial carcinoma (cT a). Among 10 cases, 5 patients refused radical nephroureterectomy(RUN), among whom 3 patients were too old or in poor general condition to tolerate RNU. One case had a solitary kidney and 1 case had bilateral tumours. Patients were treated with Thulium laser tumor ablation under ureteroscopy combined with systemic therapy. The perioperative systemic treatment included platinum-based chemotherapy±immunotherapy, RC48+ immunotherapy, and immunotherapy alone. The postoperative treatment was immunotherapy maintenance±local radiotherapy. Strict follow-up was conducted after the completion of treatment. Results:Nine patients received systemic therapy before ablation. Four cycles of platinum-based chemotherapy (cisplatin in 2 cases, carboplatin in 1 case) were used in 3 cases, and platinum-based chemotherapy + immunotherapy (6 cycles of cisplatin + toripalimab in 1 case, 4 cycles of cisplatin + toripalimab in 1 case, 4 cycles of carboplatin+ trelizumab in 1 case) was used in 3 cases, four cycle of RC48 + immunotherapy (toripalimab or trelizumab) were used in 2 cases, and four cycles of immunotherapy (toripalimab) were used in 1 case. The operations of 10 cases were successfully completed without serious complications during the perioperative period and the laser working time (42.4 ± 15.2) min. Of the 10 cases, 4 achieved complete ablation at the first ablation, and 6 patients had incomplete ablation. Among them, 2 patients achieved clinical complete remission after 1-2 cycles of systemic therapy, and 4 patients achieved complete ablation after Thulium laser ablation again.All the 10 patients were treated with immunotherapy for 1 year, and 2 of them received additional adjuvant radiotherapy. The patients were followed-up for median 40 months(range 26 to 53 months). Recurrence occurred in 5 cases, of which 3 cases underwent salvage nephroureterectomy and 2 cases underwent Thulium laser ablation under ureteroscopy again. Five patients had no tumor recurrence. None of the 10 patients had distant metastasis. At the last follow-up, 1 patient died of complications and 6 patients kept the affected kidney alive. Perioperative complications including macroscopic hematuria (8 cases), fever (3 cases), the long-term complications of ureter stenosis (4 cases).Conclusions:For localized high-risk UTUC, local Thulium laser ablation combined with systemic therapy can achieve good tumor control while preserving the affected kidney in selected patients, and its potential application value should be further evaluated.

Objective:To investigate the clinical features of placental thrombosis complicated with fetal growth restriction(FGR),and to analyze its diagnosis and treatment methods. Methods:Combined with reviewing the relevant literatures, the clinical data of a case of placental thrombosis complicated with FGR was retrospectively analyzed. The patient with 32 1/7 weeks of gestation was hospitalized due to placental blood sinus found one month ago;at the same time FGR was found by ultrasound examination. The patient was intravenously given nutritional support treatment such as amino acid and glucose.At the same time, the patient was continuously given low-flow oxygen. Results:The patient received cesarean section at 35 2/7 weeks of gestation and a baby girl with 1 280 g weight and 32 cm length was gained;many blood sinus in the maternal surface of placenta were seen with the largest diameter of 3-4cm;the placenta was hypertrophic, weighted 540 g .After operation,the newborn was transferred to Department of Neonatology and followed up for 1 month.1 month later, the infant could eat by herself, other physical examinations were finished without any obvious abnormal findings and the newbron discharged from hospital after recovery. Conclusion:Placental thrombosis complicated with FGR is very common in clinic and this disease severely endangers the neonatal health. Early diagnosis and reasonable treatment can improve the pregnancy outcomes.

Objective:To construct the recombinant prokaryotic plasmid to express HCV HLA-A2 restricted multi-CTL epitopes and to purify the fused protein for antigenic analysis.Methods:The human ubiquitin gene and multi-CTL epitopes gene was synthesized respectively,and digested by restrict enzyme before being cloned into pRSET-A.Then it was transformed into E.coli DH5α and the positive recombinant plasmid named pRSET-Ub-Mep was sequenced.Target protein was distinctly expressed after transformed into E.coli BL21 and induced with IPTG.Thus the protein was scanned and purified on Ni~(2+)-NTA column as well as Western blot performed after solubility analysis.Results:The recombinant plasmid pRSET-Ub-Mep was successfully constructed and it could efficiently express the target gene.Protein production was mainly in inclusion body and could be purified through Ni~(2+)-NTA column.The purified protein kept the antigen activity.Conclusion:The gene encoding for HCV HLA-A2-restricted multi-CTL epitopes is efficiently expressed and the target protein is purified,which establishes a foundation of further research to evaluate the cellular immune response induced by the target gene.
