XueBiJing is an intravenous five-herb injection used to treat sepsis in China.The study aimed to develop a liquid chromatography-tandem mass spectrometry(LC-MS/MS)-or liquid chromatography-ultraviolet(LC-UV)-based assay for quality evaluation of XueBiJing.Assay development involved identifying marker constituents to make the assay therapeutically relevant and building a reliable one-point cali-brator for monitoring the various analytes in parallel.Nine marker constituents from the five herbs were selected based on XueBiJing's chemical composition,pharmacokinetics,and pharmacodynamics.A selectivity test(for"similarity of response")was developed to identify and minimize interference by non-target constituents.Then,an intercept test was developed to fulfill"linearity through zero"for each analyte(absolute ratio of intercept to C response,＜2％).Using the newly developed assays,we analyzed samples from 33 batches of XueBiJing,manufactured over three years,and found small batch-to-batch variability in contents of the marker constituents(4.1％-14.8％),except for senkyunolide I(26.5％).

This study compared the transcriptome of Atractylodes lancea rhizome at different development stages and explored genes encoding the key enzymes of the sesquiterpenoid biosynthesis pathway. Specifically, Illumina NovaSeq 6000 was employed for sequencing the cDNA libraries of A. lancea rhizome samples at the growth stage(SZ), flowering stage(KH), and harvesting stage(CS), respectively. Finally, a total of 388 201 748 clean reads were obtained, and 16 925, 8 616, and 13 702 differentially expressed genes(DEGs) were identified between SZ and KH, KH and CS, and SZ and CS, separately. Among them, 53 genes were involved in the sesquiterpenoid biosynthesis pathways: 9 encoding 6 enzymes of the mevalonic acid(MVA) pathway, 15 encoding 7 enzymes of the 2-C-methyl-D-erythritol-4-phosphate(MEP) pathway, and 29 of sesquiterpenoid and triterpenoid biosynthesis pathway. Weighted gene co-expression network analysis(WGCNA) yielded 12 genes related to sesquiterpenoid biosynthesis for the SZ, 1 gene for the KH, and 1 gene for CS, and several candidate genes for sesquiterpenoid biosynthesis were discovered based on the co-expression network. This study laid a solid foundation for further research on the sesquiterpenoid biosynthesis pathway, analysis of the regulation mechanism, and mechanism for the accumulation of sesquiterpenoids in A. lancea.

Atractylodis Rhizoma(AR) is a traditional Chinese medicinal material for food and medicine, with the functions of eli-minating dampness, strengthening the spleen, expelling wind evil and dispersing cold. AR contains a variety of compounds, including sesquiterpenoids, alkynes, triterpenoids, aromatic glycosides, polysaccharides and so on. At present, the researches on AR mainly focus on volatile components, with relatively fewer researches on non-volatile components. Polysaccharide from Atractylodis Rhizoma(ARP) is an important material basis among non-volatile components for the efficacy. Due to its many biological activities such as immunomodulatory activity, anti-tumors, anti-virus and anti-oxidation, ARP has certain research value and potential. The diversity of the polysaccharide structure is the basis for biological functions, but it also increases the difficulty of carbohydrate research. The research on the extraction, separation, purification, structure and activity of ARP is in the preliminary exploration stage, still with many shortcomings. Herein, recent advancements in the extraction, purification, structural characteristics and biological activities of ARP were summarized in this article to provide scientific reference for the in-depth systematic research of ARP and the development of AR resources.

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

OBJECTIVE: To investigate the effects of different routes in placental mesenchymal stem cells (PMSC) on serum expression levels of IL-4, IL-17, TNF-α and IFN-γ in aplastic anemia (AA) rats. METHODS: The rat model of aplastic anemia (AA rats) was established by 5-fluorouracil combined with busulfan. The rats was divided into four groups: control, experimental, PMSC-injected into the tail vein, and PMSC-injected into the medullary cavity. The general state of rats in each group was observed in detail before and after treatment. The serum levels of interleukin-4 (IL-4) , interleukin-17 (IL-17), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ) were measured by enzyme-linked immunosorbent assay (ELISA) at week 1, 3 and 5 after treatment. RESULTS: The serum levels of TNF-α, IFN-γ and IL-17 in the experimental group were significantly higher than those in the control group, while the level of IL-4 was significantly decreased (P＜0.05). The levels of TNF-α, IFN-γ and IL-17 gradually decreased after treatment while the level of IL-4 increased. By the fifth week, the above indexes were closed to the control group (P＞0.05), and the levels of TNF-α, IFN-γ and IL-17 in the group with PMSCs injected via the medullary cavity decrease more significantly than those group with PMSC injected via the tail vein, but level of IL-4 was not significantly different between two groups. CONCLUSION The level of serum hematopoietic negative regulators increase significantly, and the level of hematopoietic promoting factors decreases significantly in aplastic anemia rats. PMSC can down-regulate the level of hematopoietic negative regulators and up-regulate the level of hematopoietic promoting factors in the rats with aplastic anemia, and the inhibition of hematopoietic negative regulators by intramedullary injection is more significant than that by caudal vein injection.

Objective Make use of image dentate nucleus and the veins around it on susceptibility weighted images (SWI), explore the correlation between the location of hilum of dentate nucleus and the venous variation of dentate nucleus. Methods Selecting 51 healthy adults (24 men, 27 women) at the age between 18 and 30 years old to get the original images on 3. 0T MR. Process the original images by minimum intensity projections (mIP) observed and analyzed the morphology of dentate nucleus and veins around it on original and processed images. Results The length of dentate nucleus was (16. 64±0. 20)mm, and the width was (8. 36±0. 14)mm. There was no significant difference between bilateral dentate nucleus. The median angle of the long axis of the dentate nucleus was 26. 80° (interquartile distance was 34. 58°). The venous network of dentate nucleus was formed in 2 groups of veins: the lateral group, drained by the vein of the horizontal fissure and nuclear vein; the medial group, drained by vermian vein and central vein of dentate nucleus. These two groups had been further typing as follows: the lateral anterior group drained by the nuclear vein, finally opening to superior petrosal sinus; the lateral median group had plenty of small veins of lateral dentate nucleus converge into the vein of the horizontal fissure; the lateral posterior group drained by a lot of very small veins converging to vermian veins or medullary veins; the medial anterior group that the central vein of dentate nucleus and the paravermian vein were jointed at hilum of dentate nucleus, opening into straight sinus; the medial posterior group usually converged into tributaries of vermian vein, or converged with paravermian vein into tributaries of vermian vein. Totally 75. 49% of hilums of dentate nucleus were located at upper inner quadrant, the other 24. 51% of them were located at lower inner quadrant. Conclusion Dentate nucleus and its veins are clearly visible on the susceptibility weighted images, and the location of the hilum of dentate nucleus may be related to the abouchement of paravermian vein.

Background: Disease-modifying therapy is the standard treatment for patients with multiple sclerosis (MS) in remission. The primary objective of the current analysis was to assess the efficacy and safety of two teriflunomide doses (7 mg and 14 mg) in the subgroup of Chinese patients with relapsing MS included in the TOWER study. Methods: TOWER was a multicenter, multinational, randomized, double-blind, parallel-group (three groups), placebo-controlled study. This subgroup analysis includes 148 Chinese patients randomized to receive either teriflunomide 7 mg (n = 51), teriflunomide 14 mg (n = 43), or placebo (n = 54). Results: Of the 148 patients in the intent-to-treat population, adjusted annualized relapse rates were 0.63 (95% confidence interval [CI]: 0.44, 0.92) in the placebo group, 0.48 (95% CI: 0.33, 0.70) in the teriflunomide 7 mg group, and 0.18 (95% CI: 0.09, 0.36) in the teriflunomide 14 mg group; this corresponded to a significant relative risk reduction in the teriflunomide 14 mg group versus placebo (-71.2%, P = 0.0012). Teriflunomide 14 mg also tended to reduce 12-week confirmed disability worsening by 68.1% compared with placebo (hazard ratio: 0.319, P = 0.1194). There were no differences across all treatment groups in the proportion of patients with treatment-emergent adverse events (TEAEs; 72.2% in the placebo group, 74.5% in the teriflunomide 7 mg group, and 69.8% in the teriflunomide 14 mg group); corresponding proportions for serious adverse events were 11.1%, 3.9%, and 11.6%, respectively. The most frequently reported TEAEs with teriflunomide versus placebo were neutropenia, increased alanine aminotransferase, and hair thinning. Conclusions: Teriflunomide was as effective and safe in the Chinese subpopulation as it was in the overall population of patients in the TOWER trial. Teriflunomide has the potential to meet unmet medical needs for MS patients in China.
