Fritillariae Cirrhosae Bulbus is the dried bulb of perennial herbaceous plants in the Fritillaria genus(Liliaceae family) and is a representative traditional Chinese medicinal material with distinctive regional characteristics. Clinically, it is widely used in the treatment of dry cough, bronchial asthma, and other respiratory diseases, possessing significant medicinal and economic value and being highly esteemed in TCM. Currently, Fritillariae Cirrhosae Bulbus primarily relies on wild harvesting. However, due to excessive collection, its wild resources have drastically declined, and all source species have been classified as category Ⅱ in the List of National Key Protected Wild Plants, exacerbating the supply-demand imbalance in the market. To mitigate this issue, large-scale cultivation through the domestication of wild Fritillariae Cirrhosae Bulbus has become an inevitable trend. However, its strict environmental requirements, low propagation efficiency, high seedling mortality, and immature cultivation techniques have severely hindered industrialization. This study investigates the domestication process of Fritillariae Cirrhosae Bulbus, focusing on seed propagation, seedling cultivation, and medicinal material production. It also reviews the species and distribution of wild resources, their endangered status, market supply-demand dynamics, and the historical and current development of domestication. The findings indicate that enhancing propagation efficiency, optimizing cultivation models, and distinguishing between seed propagation and medicinal material production are key measures to accelerate the industrialization of domesticated Fritillariae Cirrhosae Bulbus. This research aims to promote the industrialization of Fritillariae Cirrhosae Bulbus domestication and provide a reference model for the conservation and sustainable utilization of rare and endangered medicinal plant resources.

OBJECTIVE: To investigate the role of multiple serological methods in the identification of complex antibodies. METHODS: The blood group antigens were detected by saline and microcolumn agglutination methods. The saline method was used to screen and identify IgM-type antibodies in the patient's serum, while the polybrene, anti-globulin, microcolumn agglutination, enzymic and absorption-elution methods were used to screen and identify IgG-type antibodies. RESULTS: The patient was B/CCDee/Jk(a-b+)/Fy(a-b+) blood type. The serum reacted with panel cells, and the reaction presented anti-E pattern in the saline medium. It was fully positive in the microcolumn agglutination card, except 2 negative ones after using papain to treat the panel cells. Referring to the pattern table, it was concluded that there existed anti-c, anti-E, and anti-Jk^a antibodies, and one antibody corresponding to an antigen that was easily destroyed by papain. The red blood cells with specific phenotype were selected for absorption-elution to identify IgG-type anti-c, anti-E, anti-Jk^a and anti-Fy^a antibodies. CONCLUSION It is confirmed that IgM-type anti-E, and IgG-type anti-c, anti-E, anti-Jk^a and anti-Fy^a antibodies exist in the patient's serum by multiple serological methods.

China has a long history of Salviae Miltiorrhizae Radix et Rhizoma processing with multiple methods available. The pre-sent study collated and summarized the Salviae Miltiorrhizae Radix et Rhizoma processing methods recorded in 23 related herbal medicine books, all editions of Chinese Pharmacopoeia, the 1988 edition of National Regulations for Processing of Chinese Medicine, and 20 current local processing specifications and standards. The results demonstrated various processing methods of Salviae Miltiorrhizae Radix et Rhizoma, such as removing residual part of stem, plantlet, or soil, smashing, filing, cutting, decocting, washing with wine, soaking in wine, and stir-frying with wine or blood from pig heart, while raw and wine-processed products are mainly used in modern times. Due to the lack of unified standards, the phenomena of multiple methods adopted in one place and different methods in different places have led to uneven quality of Salviae Miltiorrhizae Radix et Rhizoma pieces, even affecting the safety and effectiveness of its clinical medication. This study is expected to provide a reference for the development of Salviae Miltiorrhizae Radix et Rhizoma processing and its rational medication.

Objective:To compare the chemical constituents of Puerariae Flos from three different varieties of Pueraria montana var. lobata， P. montana var. thomsonii and P. montana var. montana. Method:Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF-MS） was used with the mobile phase of 0.1% formic acid aqueous solution （A）-acetonitrile （B） for gradient elution （0-20 min， 10%-30%B； 20-30 min， 30%-55%B； 30-35 min， 55%-95%B； 35-37 min， 95%B； 37-40 min， 95%-10%B）， the flow rate was 0.25 mL·min^-1. Electrospray ionization （ESI） was used to scan and collect MS data in positive and negative ion modes with scanning range of m/z 50-1 500. The chemical components from different sources of Puerariae Flos were identified in combination with the chemical composition database and literature information. After the obtained data were normalized by MarkerView^TM 1.2.1， they were imported into SICMA-P 14.1 software for principal component analysis （PCA） and orthogonal partial least squares discriminant analysis （OPLS-DA） to select the main differentiated components among the three different varieties. Result:A total of 35 compounds were identified from three different varieties of Puerariae Flos， including 22 isoflavones， 6 flavonoids and 7 saponins. The flowers of P. lobata， P. montana var. thomsonii and P. montana var. montana contained 32， 35， 33 compounds， respectively. And 18 differential compounds were screened under the positive and negative ion modes， including kakkalide， tectoridin， 6″-O-xylosyl-tectoridin， 4'-methyltectorigenin-7-glucoside， glycitin， 6″-O-xylosyl-glycitin， irisolidone， kaikasaponin Ⅲ， 6″-O-malonylglycitin， kakkalidone， tectorigenin， rutin， soyasaponin BB， vitexin， biochanin A， genistin， kakkatin， azukisaponin Ⅱ. Conclusion:This research is the first to systematically study the chemical constituents of the flower of P. montana var. montana， although the flower of P. montana var. montana is used as adulterants， it has high contents of tectoridin and 6″-O-xylosyl-tectoridin， which has great potential for development. The efficacy components such as kakkalide and tectoridin in Puerariae Flos from the three sources of varieties are obviously different， and it is necessary to carefully consider the application of these three varieties as Puerariae Flos.

BACKGROUND: Bendamustine was approved in China on May 26th, 2019 by the National Medical Product Administration for the treatment of indolent B-cell non-Hodgkin lymphoma (NHL). The current study was the registration trial and the first reported evaluation of the efficacy, safety, and pharmacokinetics of bendamustine in Chinese adult patients with indolent B-cell NHL following relapse after chemotherapy and rituximab treatment. METHODS: This was a prospective, multicenter, open-label, single-arm, phase 3 study (NCT01596621; C18083/3076) with a 2-year follow-up period. Eligible patients received bendamustine hydrochloride 120 mg/m2 infused intravenously on days 1 and 2 of each 21-day treatment cycle for at least six planned cycles (and up to eight cycles). The primary endpoint was the overall response rate (ORR); and secondary endpoints were duration of response (DoR), progression-free survival (PFS), safety, and pharmacokinetics. Patients were classified according to their best overall response after initiation of therapy. Proportions of patients in each response category (complete response [CR], partial response [PR], stable disease, or progressive disease) were summarized along with a two-sided binomial exact 95% confidence intervals (CIs) for the ORR. RESULTS: A total of 102 patients were enrolled from 20 centers between August 6th, 2012, and June 18th, 2015. At the time of the primary analysis, the ORR was 73% (95% CI: 63%-81%) per Independent Review Committee (IRC) including 19% CR and 54% PR. With the follow-up period, the median DoR was 16.2 months by IRC and 13.4 months by investigator assessment; the median PFS was 18.6 months and 15.3 months, respectively. The most common non-hematologic adverse events (AEs) were gastrointestinal toxicity, pyrexia, and rash. Grade 3/4 neutropenia was reported in 76% of patients. Serious AEs were reported in 29 patients and five patients died during the study. Pharmacokinetic analysis indicated that the characteristics of bendamustine and its metabolites M3 and M4 were generally consistent with those reported for other ethnicities. CONCLUSION: Bendamustine is an active and effective therapy in Chinese patients with relapsed, indolent B-cell NHL, with a comparable risk/benefit relationship to that reported in North American patients.

The identification of species primordium has been one of the hot issues in the identification of traditional Chinese medicine. Sea snake is one of the most valuable Chinese medicinal materials in China. In order to understand the origin and varieties of sea snake in the market, we studied the molecular identification of 46 sea snakes by cytochrome B(Cytb). After comparison and manual correction, the sequence length was 582 bp, and the content of A+T(58.9%) was higher than that of G+C(41.1%). There exist 197 variable sites and 179 parsimony-informative sites of the sequence. There are 44 kinds of sequence alignment with consistency equal to 100%, and 2 kinds equal to 96%. A total of 408 Cytb effective sequences were downloaded from GenBank database, with a total of 68 species. Phylogenetic tree of a total of 454 sea snake sequences with the samples in this study were constructed by neighbor-joining trees and Bayesian inference method, respectively, which can identify 42 samples of medicinal materials, while 4 samples can not be identified because of their low node support. The results showed that the species of the sea snake medicine were at least from 2 genera and 5 species, namely, Aipysurus eydouxii, Hydrophis curtus, H. caerulescen, H. curtus, H. ornatus and H. spiralis. This study suggested that the original species of commercial sea snake are very complex and can provide insight into the identification of sea snakes.

【Objective】 To explore the regulatory mechanism of miR-204-3p targeting EphB2 gene on proliferation, apoptosis and invasion of NSCLC. 【Methods】 A549 cells were cultured and divided into 5 groups: NC mimic group, miR-204-3p mimic group, OE NCgroup, OE EphB2 group, miR-204-3p mimic+ OE EphB2 group. MTT, flow cytometry, Transwell and scratch test were used to detect cell proliferation, cycle, apoptosis, invasion and migration. Double Luciferase Report was used to analyze the targeting relationship between mir-204-3p and EphB2. The mRNA and protein expression of miR-204-3p, EphB2 were detected by qPCR and WB. 【Results】 Innon-small lung cancer cells, the binding site of mir-204-3p and EphB2 3'UTR region, the high expression of miR-204-3p significantly inhibited the expression of EphB2 mRNA and protein(P<0.01). Compared with the Negtively control group(NC mimic group), the proliferation of A549 cells in miR-204-3p mimicgroup were significantly decrease(P<0.05), and the apototic rate was significantly increased(P<0.05). Also, the cell migration and invasion ability were also decreased significantly(P<0.05). Transfection of Ephb2 reversed the above changes. In addition, in non-small cell lung cancer tissues, miR-204-3p was negatively correlated with EphB2 expression(r=0.636, P<0.001), and the overall survival was shorter in EphB2 high expression groups than that in low expression groups(logrank χ²=3.899, P=0.049) . 【Conclusion】 MiR- 204- 3p inhibits proliferation, migration and invasion of non-small lung cancer cells and induces apoptosis by down-regulating EphB2.

Objective To investigate functional connectivity between the two hemispheres in patients with positive symptoms of schizophrenia using voxel-mirrored homotopic connectivity ( VMHC ) based on resting-state functional magnetic resonance imaging (rs-fMRI). Methods Eighteen patients with positive symptoms of schizophrenia and 22 healthy controls underwent the rs-fMRI. The whole brain VMHC was calculated in order to provide imaging basis for the study of the pathological mechanism of schizophrenia. Results Compared to the controls, VMHC values were decreased in the bilateral orbitofrontal cortex (t=-5.31, P<0.01), fusiform gyrus (t=-5.16, P<0.01), middle occipital gyrus (t=-5.31, P<0.01) in patients with positive symptoms of schizophrenia. Conclusion The functional coordination between homotopic brain regions is impaired in patients with positive symptoms of schizophrenia .
