Objective To explore the clinical effect of Salvianolate for treatment of coagulant function abnormality in patients with septic shock.Methods One hundred and fifty-two septic shock patients admitted to Intensive Care Unit (ICU) of Department of Critical Care Medicine,Liuzhou Municipal Liutie Central Hospital from January 2007 to June 2016 were enrolled,and they were divided into a control group (67 cases) and a Salvianolate group (85 cases) by random number table.In the control group,conventional western medicine treatment was given,while in Salvianolate group,besides conventional treatment,additionally,Salvianolate 200 mg intravenous drip was applied daily for consecutive 10 days.The levels of D-dimer and platelet count (PLT) were examined on the 1st,3rd,7th,10th day after admission;disseminated intravascular coagulation (DIC) incidence and mortality were observed in 10 days after admission in the two groups.Results The levels of D-dimer were significantly lower in the Salvianolate group than those of the control group on 3,7,10 days after admission (mg/L:3 days was 9.14 ± 2.25 vs.18.42 ± 3.15,7 days was 6.71 ± 1.49 vs.14.57 ± 1.81,10 days was 1.01-± 0.20 vs.4.79-± 0.81,all P < 0.01).In both groups,on the first day after admission the level of PLT began to decrease,on the 3th,7th day the levels were lowered significantly,and on the 10th day,the level of PLT was elevated;in the Salvianolate group,the levels of PLT were obviously higher on the 3rd,7th,10th day after admission than those of the control group [PLT (x 109/L) 3 days after admission:67.05-± 7.76 vs.40.97 ± 6.51,7 days:67.24 ± 6.35 vs.32.06 ± 5.13,10 days:90.18 ± 11.42 vs.59.04 ± 6.57,all P <0.01].The DIC incidence and mortality were significantly lower in the Salvianolate group than those of the control group [DIC incidence:12.94% (11/85) vs.38.8% (26/67),mortality:5.88% (5/85) vs.29.85% (20/67),both P <0.01].Conclusions Coagulant function abnormality was found in most patients with septic shock.The cause of PLT decreasing is mainly due to micro-vascular thrombosis that consumes a lot of PLT.Early intervention with Salvianolate in such patients can inhibit thrombosis,block the exhaustion of PLT and correct the coagulant function abnormality with certain efficacy in the patients.

A new phenethanol, (2'R)-4-(2', 3'-dihydroxy-3'-methyl-butanoxy)-phenethanol (1), along with other eleven known benzene derivatives (2-12) were isolated from the roots, stems and leaves of Clausena excavata (Rutaceae). Compounds 3 and 4 are new natural products, and compounds 5-8, 10-12 were isolated from C. excavata for the first time. Their structures were elucidated on the basis of MS, 1D and 2D NMR spectroscopic analyses including HSQC, COSY and HMBC experiments. 1 was tested for its cytotoxicities against A549, HeLa and BGC-823 cancer cell lines, and antimicrobial activities against Candida albicans and Staphylococcus aureus. The results showed that 1 did not exhibit cytotoxic and antimicrobial activities.

Natural cyclopeptides are hot spots in chemical and pharmaceutical fields because of the wide spreading bio-resources, complex molecular structures and various bioactivities. Bio-producers of cyclopeptides distribute over almost every kingdom from bacteria to plants and animals. Many cyclopeptides contain non-coded amino acids and non-pepditic bonds. Most exciting characteristic of cyclopeptides is a range of interesting bioactivities such as antibiotics gramicidin-S (2), vancomycin (3) and daptomycin (4), immunosuppressive cyclosporin-A (1) and astin-C (8), and anti-tumor aplidine (5), RA-V (6) and RA-VII (7). Compounds 1-4 are being used in clinics; compounds 5-8 are in the stages of clinical trial or as a candidate for drug research. In this review, the progress in chemical and bioactive studies on these important natural bioactive cyclopeptides 1-8 are introduced, mainly including discovery, bioactivity, mechanism, QSAR and synthesis.

One new dicyclopeptide cyclo-(L-N-methyl Glu-L-N-methyl Glu) (1), together with one new natural dicyclopeptide cyclo-(L-methyl Glu ester-L-methyl Glu ester) (2), and two known dicyclopeptides cyclo-(L-methyl Glu ester-L-Glu) (3), and cyclo-(L-Glu-L-Glu) (4), were isolated from the aerial parts of Dianthus chinensis L. Their structures were determined by spectroscopic analyses and chemical methods.

OBJECTIVETo study the chemical constituents in fruit of Alpinia oxyphylla and their cytotoxicities on cancer cell lines.
METHODCompounds were isolated and purified by various column chromatographic methods. Their structures were determined by physico-chemical properties and spectral analyses. Compound cytotoxicity was assessed by the sulforhodamine B (SRB) assay.
RESULTEight compounds were obtained from Me2CO-H2O (70%) extract of the fruit of A. oxyphylla and their structures were identified as: (9E)-humulene-2, 3; 6, 7-diepoxide (1), 3(12), 7(13), 9(E)-humulatriene-2, 6-diol (2), (-)-oplopanone (3), yakuchinone A (4), yakuchinone B (5), tectochrysin (6), isovanillin (7), (2E, 4E)-6-hydroxy-2, 6-dimethylhepta-2, 4-dienal (8), and the cytotoxicities of compounds 1, 3-5 on cancer cell lines, A549, HT-29 and SGC-7901, were also investigated.

Objective:To investigate the safety and efficacy of FOLFOX (5-fluorouracil + calcium folinate + oxaliplatin) hepatic arterial infusion chemotherapy (FOLFOX-HAIC) combined with immune and targeted therapy as triple combination therapy for patients with single China Liver Cancer Staging (CNLC) Ⅰb hepatocellular carcinoma.Methods:A total of 20 patients with single CNLC Ⅰb hepatocellular carcinoma who received FOLFOX-HAIC combined with immune and targeted therapy as triple combination therapy in the First Affiliated Hospital of Guangxi Medical University from October 2021 to August 2022 were included. The clinical data of all patients was retrospectively analyzed. There were 18 males and 2 females, with the age of (55.1±9.9) years. Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and Modified Response Evaluation Criteria in Solid Tumors (mRECIST) were used to evaluate the efficacy of FOLFOX-HAIC combined with immune and targeted therapy, and the clinical safety of triple combination therapy was evaluated by common terminology criteria for adverse events 4.0.Results:According to RECIST 1.1, objective response rate of 20 patients was 70.0% (14/20) and disease control rate was 100.0% (20/20) after 2 cycles of treatment (one cycle of FOLFOX-HAIC plus programmed death-1 antibody). According to mRECIST, objective response rate was 90.0% (18/20) and the disease control rate was 100.0% (20/20) after 2 cycles of treatment. Following the treatment, 12 patients (60.0%) received liver tumor resection, and all of them achieved R 0 resection, 2 patients (10.0%) received radiotherapy, 3 patients (15.0%) stopped drug treatment for surgery, 2 patients (10.0%) refused surgery, and 1 patient (5.0%) died of multiple organ failure caused by immune hepatitis. According to pathological results, 3 patients (25.0%, 3/12) achieved pathological complete response, and 4 patients (33.3%, 4/12) achieved major pathological response. In the safety evaluation, the overall incidence of adverse events was 100.0% (20/20). Seven patients (35.0%) had grade 3 adverse events and 1 patient (5.0%) died of multiple organ failure due to immune hepatitis (grade 5). Grade 1-3 adverse events could be relieved after symptomatic treatment. Conclusion:The triple combination therapy of FOLFOX-HAIC combined with immune and targeted therapy is safe and has high objective response rate and disease control rate, which could be a new strategy for the neoadjuvant treatment of hepatocellular carcinoma.
