Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

ObjectiveTo investigate the mRNA expression levels of various aquaporins (AQPs) in luteinized granulosa cells from follicles of different diameters. MethodsFrom March 25, 2022 to September 23, 2022 in our reproductive medicine center, 48 women undergoing in-vitro fertilization (IVF) were enrolled and divided into the antagonist group and the agonist group according to the ovarian stimulation protocol. Follicular fluid samples were collected on the day of oocyte pick-up and granulosa cells were extracted from follicles of different diameters: small (<13 mm), medium (13~18 mm) and large (≥18 mm). After RNA quantification, 22 cases (66 samples) were included for analysis and mRNA expression levels of AQPs were compared among the three follicle groups. ResultsThe mRNA expression of aquaporin 2 (AQP2) in luteinized granulosa cells increased with the increase of follicle diameter (linear trend P = 0.004) and the difference was statistically significant between two groups of large and small follicles (P = 0.017). Statistical difference was found in the antagonist group (P = 0.049 6), but not in the agonist group (P = 0.108). ConclusionThe mRNA level of AQP2 in luteinized granulosa cells increases with the increase of follicle diameter and its expression is related to the ovarian stimulation protocol, suggesting that AQP2 may play a role in follicle growth and follicular fluid formation, and its mRNA expression level may be regulated by follicle stimulating hormone (FSH) and luteinizing hormone (LH).

Pathogenic bacterial infection is one of the main clinical symptoms. Antibiotics are widely used in clinical practice to inhibit or kill the bacteria, fungi and other pathogenic microorganisms. However, with the massive use of antibiotics, drug-resistant strains continue to appear that make the antibacterial situation is becoming increasingly severe. Due to the advantages of multiple targets, multiple pathways and multiple components, traditional Chinese medicine (TCM) have gradually attracted more attention and were used in antibacterial treatment. However, some antimicrobial TCM have problems such as low solubility, poor stability, and low bioavailability. Improving and enhancing the antibacterial activity of TCM through preparation technology is one of the effective solutions. Based on this, two aspects of unilateral antibacterial TCM preparation technology and combination antibacterial preparation technology are introduced, including inclusion technology, nanotechnology, electrospinning, 3D printing and others. Distinctive features and specific application effects of these preparation technologies are explained firstly, and then their advantages and disadvantages are compared and analyzed. The review can be a useful reference for improving the antibacterial activity of TCM.

OBJECTIVE:
To observe the regulatory effect of electroacupuncture (EA) on small airway function and exercise tolerance in patients with stable chronic obstructive pulmonary disease (COPD).
METHODS:
A total of 62 patients with stable COPD were randomized into an observation group (31 cases, 1 case dropped off) and a control group (31 cases, 5 cases dropped off). On the base of routine medication and aerobic exercise, the patients of the two groups all received EA at Danzhong (CV 17), Rugen (ST 18), Guanyuan (CV 4), Zhongwan (CV 12), Tianshu (ST 25) and Yingchuang (ST 16). In the observation group, filiform needles were used and inserted perpendicularly, 3 mm in depth. In the control group, the placebo needling method was performed, in which the needle was not inserted through skin at each point. In both groups, electric stimulation with low-frequency electronic pulse instrument was exerted, with continuous wave, 2 Hz in frequency, lasting 30 min each time in the two groups. The treatment was given once every other day, 3 times a week, for 14 treatments totally. Before and after treatment, the following indexes were compared in patients between the two groups, i.e. the lung function indexes (forced expiratory volume in first second [FEV1], forced vital capacity [FVC], the ratio of FEV1 to FVC [FEV1/FVC], maximal voluntary ventilation [MVV], the percentage of maximal expiratory flow [MEF] at 25% of FVC exhaled [MEF25], MEF50 and MEF75 in predicted value), cardiopulmonary exercise test indexs (metabolic equivalent [METS], oxygen uptake per kg body weight [VO
RESULTS:

A new method for qualitative and quantitative analysis of Rhodobryum giganteum by using the nonlinear oscillating chemical was established for improving the quality control standard of R. giganteum. Its potential(E)/time(t) curve was recorded by electrochemical workstation in the oscillation reaction system of BrO~-_3-Ce(SO_4)_2-H_2SO_4-malonic acid/tartaric acid. The nonlinear oscillating chemical fingerprints were investigated for repeatability, and it was found that the RSD values of the four characteristic parameters of R. giganteum were less than 4.1%, indicating a good repeatability and high precision of this experiment. After optimizing the experimental parameters such as particle size, rotation speed and temperature, a new method based on nonlinear oscillating chemical was used for qualitative and quantitative analysis of R. giganteum. The results showed that there was a good linear relationship between the induction time/the period of oscillation and the dosage of herbs(0.1-1.1 g), with the relative coefficients of 0.978 and 0.975, respectively. Besides, the highest potential showed a nonlinear relationship with the dosage of herbs, with the relative coefficient of 0.999. This method was also used to discriminate the R. giganteum and R. roseum. They were similar in appearance, but their fingerprints were quite different. Independent sample t test results showed that there were significant differences in the oscillation time, the maximum amplitude and the induction time, providing a basis for the identification of the basic sources of Herba Rhodobryi Rasei.

Objective::To study the effect of Qiyu Sanlong decoction on the growth of subcutaneous tumor in lung cancer mice and the expressions of key autophagy molecule, yeast Atg6 homologous (Beclin1), autophagy related genes5 (Atg5), and microtubule-associated protein1 light chain3 (LC3B). Method::Lewis lung carcinoma cells (LLC) were used to reproduce the lung cancer mice transplanted model. After the modeling, the mice were randomly divided into model group, Qiyu Sanlong decoction group, chemotherapy group and combination group, with 18 transplanted mice in each group. In model group, mice were fed with 0.9% saline 20 mL·kg-1 daily. In Qiyu Sanlong decoction group, mice were fed with Qiyu Sanlong decoction 80.48 g·kg-1 daily. The chemotherapy group was intraperitoneally injected with 0.4 mL cisplatin solution (DDP) at the 1st, 3rd and 5th day. The combination group was orally given the drugs at the concentration of 80.48 g·kg-1, and 0.4 mL DDP solution was intraperitoneally injected at the 1st, 3rd and 5th day. After 21 days of continuous treatment, tumor tissue was exfoliated and weighed, and the tumor inhibition rate was calculated. Hematoxylin-eosin (HE) staining was used to observe the histological changes of tumor. The expressions and localizations of Beclin1 and LC3B in tumor tissues were detected by immunohistochemical staining. Protein expressions of Beclin1, Atg5, LC3B-Ⅰand LC3B-Ⅱ were determined by Western blot, and the ratio of LC3B-Ⅱ/LC3B-Ⅰ was calculated. The transcription levels of Beclin1, Atg5 mRNA in tumor tissues were detected by Real-time PCR. Result::Qiyu Sanlong decoction had a mild inhibitory effect on transplanted tumor, with an inhibitory rate of 31.2%. Under microscope, patchy necrotic tumor cells were observed in the tumor tissues of Qiyu Sanlong decoction group. Immunohistochemical staining and Western blot analysis showed that Qiyu Sanlong decoction could up-regulate the expressions of Beclin1, Atg5 and LC3B protein (

OBJECTIVETo identify specific protein markers for renal cell carcinoma detection and diagnosis, as well as develop new potential therapeutic targets of the disease.
METHODSWe used two-dimensional difference in-gel electrophoresis (2-D DIGE) technique conjunction with mass spectrometry (MS) for the identification of significant differentially expressed proteins between 15cases of paired clear cell renal cell carcinoma (ccRCC) and adjacent normal renal tissues. The protein spots were considered as differentially expressed if a 1.5-fold altered expression level was observed (Student's t test, P value<0.05).
RESULTSOf the 27 differentially expressed protein spots, 26 proteins were successfully identified. 11 proteins up-regulated in renal cell carcinoma,15 proteins down-regulated. Among them Short/branched chain specific acyl-CoA dehydrogenase, mitochondrial (ACDSB), Aldose 1-epimerase (GALM), Peroxiredoxin-4 (PRDX4), Macrophage-capping protein (CAPG), Beta-defensin 107 (D107A), Microfibril-associated glycoprotein 4 (MFAP4) were first time screening as new differential expressed proteins by protomic study in renal cell carcinoma.
CONCLUSIONS2-D DIGE is a useful technique for screening and analysis differential expressed proteins in renal cell carcinoma. These new differently expressed proteins may be useful for development new molecular markers for the tumor.

BACKGROUNDThree randomised trials have demonstrated that combining bevacizumab with first-line chemotherapy significantly improves progression-free survival versus chemotherapy alone in HER2-negative locally recurrent/metastatic breast cancer (LR/mBC). However, data from Chinese populations are limited and possible differences between ethnic and geographic populations are unknown. This study was conducted to determine whether there are differences in safety and efficacy in patients with HER2-negative LR/mRC between Chinese and Western populations after they receive first-line bevacizumab combined with taxane-based therapy.
METHODSIn the single-arm, open-label, Avastin Therapy for Advanced Breast Cancer (ATHENA) study (NCT00448591), patients with HER2-negative LR/mBC received first-line bevacizumab (investigator's choice of 10 mg/kg every 2 weeks or 15 mg/kg every 3 weeks) combined with taxane-based therapy. The primary endpoint was safety profile and the secondary is time to progression (TTP). A subpopulation analysis was conducted to assess safety and efficacy in Chinese patients.
RESULTSOf 2264 patients treated in ATHENA, 202 were enrolled in China. Bevacizumab was combined with docetaxel in 90% of Chinese patients and paclitaxel in 10%. The most common grade 3/4 adverse events were diarrhoea (in 5.0% of patients) and hypertension (in 2.5% of patients). Grade 3/4 proteinuria occurred in 0.5%. After median follow-up of 17.6 months and events in 56% of patients, median TTP was 9.0 months (95%CI, 8.4-11.1). Overall survival data were immature.
CONCLUSIONSWe found no evidence of increased bevacizumab-related toxicity or reduced efficacy in Chinese LR/mBC patients receiving first-line bevacizumab-taxane therapy compared with predominantly Western populations. The safety profile was generally similar to previously reported LR/mBC trials. Subtle differences may be attributable to different lifestyle and cardiovascular risk factors in Chinese patients compared with the overall population. It appears reasonable to extrapolate findings from bevacizumab-based randomised trials to Chinese populations.

BACKGROUNDPancreatic cancer is one of the most lethal human cancers with a very low survival rate of 5 years. Conventional cancer treatments including surgery, radiation, chemotherapy or combinations of these show little effect on this disease. Several proteins have been proved critical to the development and the progression of pancreatic cancer. The aim of this study was to investigate the effect of resveratrol on apoptosis in pancreatic cancer cells.
METHODSSeveral pancreatic cancer cell lines were screened by resveratrol, and its toxicity was tested by normal pancreatic cells. Western blotting was then performed to analyze the molecular mechanism of resveratrol induced apoptosis of pancreatic cancer cell lines.
RESULTSIn the screened pancreatic cancer cell lines, capan-2 and colo357 showed high sensitivity to resveratrol induced apoptosis. Resveratrol exhibited insignificant toxicity to normal pancreatic cells. In resveratrol sensitive cells, capan-2 and colo357, the activation of caspase-3 was detected and showed significant caspase-3 activation upon resveratrol treatment; p53 and p21 were also detected up-regulated upon resveratrol treatment.
CONCLUSIONResveratrol provides a promising anti-tumor strategy to fight against pancreatic cancer.
