Five flavonoid glycosides were isolated from the methanol and ethyl acetate fractions of the ethanol extract of Diphylleia sinensi by using various chromatographic methods, including silica gel, MCI gel, Sephadex LH-20, ODS and semi-preparative HPLC. The structures of the isolated compounds were identified as diphyflavonoid A (1), diphyflavonoid B (2), quercetin-3-O-β-D-glucopyranoside (3), kaempferol-3-O-β-D-glucopyranoside (4), kaempferol-3-O-(6″-O-acetyl)-β-D-glucopyranoside (5) by spectroscopy methods (1D NMR, 2D NMR, UV, IR, and MS). Compounds 1 and 2 were two new flavonoid glycosides, and compounds 3 and 5 were isolated from the genus Diphylleia for the first time.

Benign prostatic hyperplasia(BPH) is a common disease in middle-aged and elderly men, with lower urinary tract symptoms as the main manifestation, severely affecting the quality of life of patients. The pathogenesis of BPH is not yet fully understood, and there are still some challenges and limitations in western medicine treatment for BPH. Therefore, finding new and more effective treatment strategies is urgent. In recent years, many basic and clinical studies have confirmed the important role of traditional Chinese medicine in the treatment of BPH. This article reviews the progress of basic and clinical research in the treatment of BPH with traditional Chinese medicine, and believes that basic research mainly focuses on the active ingredients of Chinese medicine [regulating pathways such as NF-E2-related factor 2(Nrf2)/antioxidant response element(ARE), nuclear factor κB(NF-κB), epidermal growth factor receptor(EGFR)/signal transducer and activator of transcription 3(STAT3), phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR), p38 mitogen-activated protein kinase(p38 MAPK)/forkhead box O subtype(FOXO3a), etc.], single Chinese herbs(regulating inflammatory factors, oxidative stress-related proteins, cell cycle-related proteins, and apoptotic factors, etc.), and Chinese herbal compounds and patent medicines [regulating extracellular signal-regulated kinase(ERK1/2), transforming growth factor-β(TGF-β)/Smad, mitogen-activated protein kinase(MAPK), PI3K/Akt, Nrf2, trefoil factor 2(TFF2)/Wnt, interleukin-6(IL-6)/Janus kinase 2(JAK2)/STAT3, hypoxia-inducible factor 1α(HIF-1α)/vascular endothelial growth factor receptor(VEGFR), etc.], and then play a therapeutic role by inhibiting BPH cell proliferation, oxidative stress, inflammatory response, promoting apoptosis, and inhibiting epithelial-mesenchymal transition. Clinical studies mainly focus on internal treatment, external treatment, combined internal and external treatment, and integrated Chinese and western medicine treatment as the main methods, aiming to improve traditional Chinese medicine syndrome scores, prostate symptom scores, residual urine volume, effective bladder volume, sexual quality of life, increase average urine flow rate, maximum urine flow rate, and promote balance of sex hormone secretion. Through this research, it is hoped to provide some reference ideas for clinical research and drug development for BPH.

The application status of acupuncture and moxibustion therapy for assisted reproductive field in the United States was analyzed, and the existing problems and future development directions were discussed. According to the survey on the 456 websites of assisted reproductive clinic in the United States mentioned in the report of U.S. Centers for Disease Control and Prevention (CDC), 111 clinics among 456 assisted reproductive clinics recommend and used acupuncture and moxibustion therapy, accounting for 24.3%. Acupuncture and moxibustion therapy had obvious effect, good safety and low cost, and the assisted reproductive institutions in the United States had a high degree of application and recognition to acupuncture and moxibustion therapy. However, some problems, such as immature treatment scheme, unclear mechanism and imperfect insurance policies, still existed. In the future, the advantages of Chinese traditional acupuncture and moxibustion should combine with international modern assisted reproductive technology, and multi-center and large-sample clinical randomized controlled trials and basic experimental research on the mechanism of acupuncture and moxibustion for assisted reproduction should be carried out.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Objective:To study the distribution characteristics of mineral elements in Gastrodia elata samples with different grades and specifications （variants） from diverse producing areas and their classification and identification evidences. Method:Fourteen mineral elements in 31 batches of Gastrodia elata samples of different grades and specifications （variants） from diverse producing areas were determined by atomic absorption spectrophotometry， Mo-Sb colorimetry， and curcumin colorimetry， and then subjected to correlation analysis （CA）， discriminant analysis （DA）， and principal component analysis （PCA）. Result:The content of K， N， and P in G. elata was the highest， enabling them to serve as the nutritional limiting factors affecting its growth. The G. elata samples could be identified by the variation trend of elements （K>N>P>Mg>Ca>Fe>B>Zn>Mn>Cu>Ni>Cr>Pb>Cd）. The comparison of G. elata samples from multiple producing areas showed that G. elata from Zhaotong has the highest P， Fe， and Cd content， that from Lijiang the highest K content， that form Luotian the highest Zn and Cr content， and that from Jinzhai the highest Cu and Pb content. The content of Mg， B， Pb， and Cr in G. elata f. elata was higher than that in G. elata f. glauca. It was found that the content of P， Cu， and Cd in commercially available G. elata products gradually increased with the decrease in the commercial grade， while that of Mg， Fe， B， and Ni mostly decreased. As revealed by CA， Fe was positively correlated with Mg， Cr， and B. The producing areas of G. elata samples could be effectively identified by DA with Cd， Pb， Cr， Cu， B， and Ni as the main variables， and the accuracy reached up to 85.71%. According to the PCA of mineral elements in G. elata f. glauca from Zhaotong， Yunnan Province， Fe， Cr， Mg， Cd， P， Mn， B， Pb， and Cu exerted a greater influence on G. elata. Conclusion:The determination of mineral elements in G. elata samples contributes to identifying their authenticity and origin due to the easy operation， accurate results， and good stability.

OBJECTIVE: To study the potential significance and clinical application of FGFR1 gene abnormality in the diagnosis, clinical features, pathological mechanism and treatment in hematological tumors. METHODS: Clinical data of total of 29 patient with chromosome of 8 short arm (8P) abnormality who had more comprehensive medical history from 2013 to 2018 were collected. The karyotype analysis of bone marrow chromosomes in patients was carried out by using chromosome R band banding technique. FGFR1 gene was detected by using fluorescence in situ hybridization (FISH). RESULTS: Seven cases of FGFR1 gene abnormalities were decteted, including 3 cases of FGFR1 gene amplification, 2 cases of translocation, and 2 cases of deletion. Five patients with FGFR1 gene amplification or deletion not accompaned with eosinophilia, moreover the chromosome was a complex karyotype with poor prognosis; Two cases of FGFR1 gene translocation were non-complex chromosomal translocation and one of which survived for 6 years after bone marrow transplantation, the other chromosome karyotype showed no rearrangement of 8 short arm. However, FGFR1 gene rearrangement was confirmed by FISH analysis, which was a rare insertional translocation. CONCLUSION FGFR1 gene amplification or deletion often occur in cases with complex karyotype, which not accompany eosinophilia, moreover have poor prognosis. The patients with FGFR1 gene translocation accompany eosinophilia which is consistent with the clinical characteristics of myeloid / lymphoid neoplasms with FGFR1 abnormality. Karyotype analysis combined with FISH method can improve the detection of abnormal clones.

Objective: To analyze the effect of acupuncture versus hormone replacement therapy (HRT) for premature ovarian insufficiency (POI). Methods: China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), China Biology Medicine Disc (CBM), Web of Science, Cochrane Library, PubMed, and Excerpta Medica Database (EMBASE) were searched up to January 31st, 2019 to identify randomized controlled trials (RCTs) evaluating the effect of acupuncture for POI. The primary outcome was the level of basal serum follicle- stimulating hormone (FSH). Secondary outcomes included serum levels of luteinizing hormone (LH), estradiol (E2) and anti-Müllerian hormone (AMH). Two authors extracted data independently and assessed the risk of bias and the methodological quality using the Cochrane's tool. Meta-analysis was conducted by RevMan version 5.3. Results: Eight eligible RCTs with a total of 496 POI patients were included in the meta-analysis. The pooled results showed that there was a significant reduction in the basal serum FSH level (MD=-5.82, 95％CI:-9.76 to -1.87, I2=82％, P=0.004) and a remarkable elevation in the basal E2 level (SMD=0.93, 95％CI: 0.34 to 1.52, I2=88％, P=0.002) in the acupuncture group when compared with the control. Subgroup analysis showed that compared with HRT, a significant decrease in the FSH level was observed in both acupuncture alone (MD=-4.53, 95％CI:-8.96 to -0.10, I2=73％, P=0.04) and acupuncture plus HRT (MD=-9.60, 95％CI:-17.60 to -1.61, I2=50％, P=0.02), while a remarkable elevation of E2 was only found in acupuncture plus HRT (SMD=1.43, 95％CI: 1.03 to 1.82, I2=0％, P<0.00001). There was no significant difference in the LH level between acupuncture and HRT (MD=-3.16, 95％CI:-9.41 to 3.10, I2=0％, P=0.32), only one trial reported AMH, and no significant difference was found between acupuncture and HRT. Conclusion: The present study indicated that acupuncture had an advantage over HRT in reducing serum FSH level and increasing serum E2 level in women with POI. However, evidence supporting the finding is limited due to the small sample size, potential methodological flaws and significant heterogeneity. Hence, this conclusion still needs to be verified by high-quality RCTs.
