OBJECTIVE@#To investigate the antibacterial activity of patchouli alcohol (PA) against 127 bacteria strains, including the common bacteria and drug-resistant bacteria strains both in the in vitro and in vivo tests.@*METHODS@#For the in vitro trial, the antibacterial property of PA against 107 Gram-positive and 20 Gram-negative bacteria strains was screened by agar double dilution method. For the in vivo trial, specific pathogen free Kunming strain of both male and female white mice, were used to test the protective ability of PA after being injected with the median lethal dose of the tested strains.@*RESULTS@#PA possessed antibacterial activity against all the tested 127 strains. In the in vitro test, PA could inhibit both Gram-negative bacteria (25-768μg/mL) and Gram-positive bacteria (1.5-200μg/mL). Particularly, PA was active against some drug-resistant bacteria like methicillin-resistant Staphylococcus aureus (MRSA). PA also exhibited in vivo anti-MRSA activity in mice via intraperitoneal injection. PA could protect mice entirely infected with MRSA at 100 and 200 mg/kg, while 80% mice injected with MRSA could be protected at a low dose of 50μg/mL.@*CONCLUSION@#PA might be a potential antibacterial drug from natural sources and might be worthy to explore its mechanism and application in further study.
ABSTRACT
Dao-di herbs are the Chinese herbs which have high quality and best clinic effects. Sichuan is one of the proviences most rich in Chinese herb resources,which has 7 290 species of Chinese herbs, such as Curcumae Longae Rhizoma, Chuanxiong Rhizoma, Aconiti Lateralis Radix Praeparata, Ophiopogonis Radix, Coptidis Rhizoma, Gentianae Radix, Rhei Radix et Rhizoma, Curcumae Rhizoma, Gardeniae Fructus, ect. After textual research on materia medica of the 7 290 Chinese herbs, we find there are 86 Dao-di herbs in Sichuan, such as Chuanxiong Rhizoma from Dujiangyan, Aconiti Lateralis Radix Praeparata from Jiangyou, Fritillariae Radix, Notoptergii Rhizoma et Radix, Angelicae Dahuricae Radix from Suining, Ophiopogonis Radix from Santai, Salviae Miltiorrhizae Radix et Rhizoma from Zhongjiang, Magnoliae Officinalis Cortex from Pingwu. In China more attention is paid to the production of Dao-di herbs. In 2018, the State Administration of Traditional Chinese Medicine launched the "Construction Plan of national production base of genuine medicinal materials". Developing genuine medicinal materials in genuine production areas is one of the effective ways to ensure the quality of medicinal materials. Based on the study of geographical environment and ecological factors(altitude, climate, soil) in Sichuan province. The Dao-di herbs of Sichuan province are divided into 4 districts, including, Sichuan basin medicinal materials production area, mountain and the basin edge medicinal materials production area, Panxi medicinal materials production area, Plateau Mountain Canyon medicinal materials production area. The suitable regions and best suitable regions of the 86 Dao-di herbs in Sichuan are determined by remote sensing and GIS spatial analysis of the suitable environmental indicators of these Dao-di herbs. Our study is beneficial to the rational distribution of the production and to improvement of the quality of traditional Chinese medicine in Sichuan province.

Simultaneous inhibition of MDM2 and CDK4 may be an effective treatment against glioblastoma. A collection of chiral spirocyclic tetrahydronaphthalene (THN)-oxindole hybrids for this purpose have been developed. Appropriate stereochemistry in THN-fused spirooxindole compounds is key to their inhibitory activity: selectivity differed by over 40-fold between the least and most potent stereoisomers in time-resolved FRET and KINOMEscan® assays. Studies in glioblastoma cell lines showed that the most active compound induced apoptosis and cell cycle arrest by interfering with MDM2 -P53 interaction and CDK4 activation. Cells treated with showed up-regulation of proteins involved in P53 and cell cycle pathways. The compound showed good anti-tumor efficacy against glioblastoma xenografts in mice. These results suggested that rational design, asymmetric synthesis and biological evaluation of novel tetrahydronaphthalene fused spirooxindoles could generate promising MDM2-CDK4 dual inhibitors in glioblastoma therapy.

Objective To analyze the variations and drug resistance of influenza A (H3N2) viruses in Jiangsu Province in 2017, and provide evidence for prevention and control strategies on influenza. Methods Reverse transcription polymerase chain reaction (RT-PCR) was used for the sequencing of H3N2 subtype influenza strains. The influenza reference sequences were obtained from the global shared influenza site GISAID. The sequence alignment and phylogenetic analysis were performed using MAGE7.0 software. Viral resistance was analyzed by a neuraminidase inhibition assay. Results The H3N2 subtype influenza isolates and vaccine strains belonged to the 3C.2a branch of the H3 subtype. Some of the strains showed amino acid mutations on the immune-related sites named N121K, T135K and N171K. The isolates were sensitive to the flu drugs oseltamivir and zanamivir. Conclusion The H3N2 epidemic strains in Jiangsu have genetic recombination within subtypes and are still sensitive to neuraminidase inhibitors. As the H3N2 influenza virus mutations continue, a close monitoring of the viral genetic evolution and the drug resistant genes should be guaranteed.

ABSTRACT
MicroRNAs (miRNAs) are a family of non-coding RNA that are able to adjust the expression of many proteins, including ATP-binding cassette transporter and organic cation transporter. We sought to evaluate the effect of miR-511 on the regulation of OATP1B1 expression by free fatty acids. When using free fatty acids to stimulate Chang liver cells, we found that the expression of miR-511 increased significantly while the expression of OATP1B1 decreased. We also proved that SLCO1B1 is the target gene of miR-511 with a bioinformatics analysis and using the dual luciferase reporter assay. Furthermore, the expressions of SLCO1B1 and OATP1B1 decreased if transfecting Chang liver cells with miR-511, but did not increase when transfecting the inhibitors of miR-511 into steatosis cells. Our study indicates that miR-511 may play an important role in the regulation of OATP1B1 expression by free fatty acids.

<p><b>BACKGROUND</b>Our pervious antibacterial studies on several traditional Chinese medicines have found that Patchouli oil from Pogostemon cablin had significant antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA), which has spread worldwide and infected innumerable people. In order to find the more active natural substances in Patchouli oil, one of the major components, Pogostone, was isolated and its antibacterial activity was evaluated in vitro and in vivo in this study.</p><p><b>METHODS</b>In vitro test, Pogostone was screened for antimicrobial properties against 83 bacteria comprising 35 gram positive and 48 gram negative bacteria strains via the agar double dilution method. In vivo test, specific pathogen free (SPF) strain of both male and female white Kunming mice, weighing 18-22 g, were used to test the protective ability of Pogostone after being injected with the median lethal doses (MLDs) of the tested strains.</p><p><b>RESULTS</b>In vitro test, Pogostone could inhibit both gram negative bacteria (0.098-1 600 µg/ml) and gram positive bacteria (0.098-800 µg/ml). For Corynebacterium xerosis and some Chryseobacterium indologenes, the minimum inhibitory concentration (MIC) values of Pogostone were extremely low (<0.098 µg/ml). It was significant that Pogostone was also active against some drug-resistant bacteria like MRSA. Furthermore, Pogostone showed antibacterial activity in vivo against Escherichia coli (E. coli) and MRSA via intraperitoneal injection. Ninety percent of the mice infected with E. coil could be protected at the concentrations of 50 and 100 mg/kg, and 60% of the mice at 25 mg/kg, while the rate of protection for the mice infected with MRSA was 60% and 50% at doses of 100 and 50 mg/kg, respectively.</p><p><b>CONCLUSION</b>Pogostone could be developed as a potential antibacterial agent for clinical therapy.</p>

The herbs used as the material for traditional Chinese medicine are mostly planted at mountain areas where there is appropriate weather condition. Due to the complex terrain condition in mountain area, the planting at such places is always associated with a scattered pattern, which inevitably bring difficulty to the work of accurate measurement for the planting area. Advanced research about monitoring the planting area for medicine-herb under complex environmental condition is so critical and meaningful for developing the medicine-herb planting to a large scale and an industry. Therefore, this research, taking the planting of Herpetospermum pedunculosum in Luding county as an example, utilizes RS&GIS: using the image data from TM and ETM datum as the remote sensing information source, integrating GPS data from quadrat survey on the spots, and analyzing on a GIS platform, to extract the planting area of H. pedunculosum in Luding county. The results indicate that: (1) the method and technology used to estimate the planting area of H. pedunculosum are feasible and can be applied to monitoring the planting area of medicine-herb at mountain area under complex environmental conditions: (2) the planting area of H. pedunculosum in Luding county is estimated to be 857. 246 acres by the methods utilized in this research, which is closed to the value from local statistical data with an error range less than 5%; (3) in consideration of those inevitable errorrs generating from the procedures such as remote sensing data acquisition, data preprocessing, data interpretation, and so on, and the fact that the classification of remote sensing data, which must be implemented by those above procedures, was used directly to extract the herb type, the accuracy of area estimation for the herb is significantly influenced by the accuracy of classification for herb type, and the estimated area is inevitably associated with some error.

<p><b>BACKGROUND</b>Amputation-free survival (AFS) has been recommended as the gold standard for evaluating No-Option Critical Limb Ischemia (NO-CLI) therapy. Early-phase clinical trials suggest that autologous bone-marrow derived cells (BMCs) transplantation may have a positive effect on patients with NO-CLI, especially decreasing the incidence of amputation. However, the BMCs therapeutic efficacy remains controversial and whether BMCs therapy is suitable for all CLI patients is unclear.</p><p><b>METHODS</b>We conducted a meta-analysis using data from randomized controlled trials (RCTs) by comparing autologous BMCs therapy with controls in patients with critical limb ischemia, and the primary endpoint is the incidence of amputation. Pubmed, EBSCO and the Cochrane Central Register of Controlled Trials (to approximately July 25, 2012) were searched.</p><p><b>RESULTS</b>Seven RCTs with 373 patients were enrolled in the meta-analysis. Because serious disease was the main reason leading to amputation in one trial, six studies with 333 patients were finally included in the meta-analysis. Pooling the data of the final six studies, we found that BMCs therapy significantly decreased the incidence of amputation in patients with CLI (odds ratio (OR), 0.37; 95% confidence interval (CI), 0.22 to 0.62; P = 0.0002), and the efficacy had not significantly declined within 6 months after BMCs were transplanted; OR, 0.33; 95%CI, 0.16 to 0.70; P = 0.004 within 6 months and OR, 0.30; 95%CI, 0.11 to 0.79; P = 0.01 within 3 months. The rate of AFS after BMCs therapy was significantly increased in patients with Rutherford class 5 CLI (OR 3.28; 95%CI, 1.12 to 9.65; P = 0.03), while there was no significant improvement in patients with Rutherford class 4 (OR 0.35; 95%CI, 0.05 to 2.33; P = 0.28) compared with controls. The BMCs therapy also improved ulcer healing (OR, 5.83; 95%CI, 2.37 to 14.29; P = 0.0001).</p><p><b>CONCLUSIONS</b>Our analysis suggests that autologous BMCs therapy has a beneficial effect in decreasing the incidence of amputation and the efficacy does not decrease significantly within 6 months after BMCs transplantation. Patients with Rutherford class 5 are suitable for BMCs therapy, while the efficiency in patients with Rutherford 4 needs further evaluation.</p>

<p><b>OBJECTIVE</b>To study the effects of brucine on vascular endothelial growth factor (VEGF) expression and microvessel density (MVD) in a nude mouse model of bone metastasis due to breast cancer, and to assess the possible antitumor mechanism of brucine.</p><p><b>METHODS</b>A syringe needle was used to directly inject 0.2 mL monoplast suspension (with 2×10(5) human breast cancer cells contained) into the bony femoral cortex of the right hind leg for modeling. Twenty-five nude mice were randomized into five groups and administered with an intraperitoneal injection of saline or drug for 8 consecutive days: model group (0.2 mL normal saline), low-dose brucine group (1.73 mg·kg(-1)), medium-dose brucine group (3.45 mg·kg(-1)), high-dose brucine group (6.90 mg·kg(-1)), and thalidomide group (200 mg·kg(-1)). Diet and activity were recorded, and the tumors were harvested 5 weeks later. The percentage of VEGF-positive cells was determined with hematoxylin and eosin staining and immunohistochemical staining, and MVD expression was determined by optical microscopy.</p><p><b>RESULTS</b>The VEGF expressions in brucine- or thalidomide-treated mice were significantly reduced as compared with mice in the model group (P <0.01). There were no significant difference between the high-dose brucine group and the thalidomide group (P >0.05). Significant difference was between the high- and low-dose brucine group P<0.05). Further, VEGF expression was significantly increased in the low- and medium-dose brucine groups compared with the thalidomide group (P <0.05). The MVD values in the three brucine and thalidomide groups were significantly lower than that in the model group (P <0.01). The MVD values in the medium- and high-dose brucine groups were not significantly different from those in the thalidomide group (P >0.05), while the MVD value showed a significant increase in the low-dose group compared with the thalidomide group (P <0.05).</p><p><b>CONCLUSION</b>Brucine could inhibit the growth of breast cancer to bone metastases, possibly by inhibiting tumor angiogenesis.</p>

This study was aimed to retrospectively analyze and compare the clinical curative efficacy of patients with hematologic malignancies after G-CSF-mobilized sibling HLA-matched (sm) peripheral blood hematopoietic stem cell transplantation (sm-allo-PBHSCT) and sm-allo-PBHSCT combined with bone marrow transplantation (BMT). 100 patients received sm-allo-HSCT in a single center from October 2001 to October to 2010, included 38 patients received sm-allo-PBHSCT and 62 patients received sm-allo-PBHSCT combined with BMT. The myeloablative or reduced intensity conditioning regimens were chosen according to the condition of patients. All patients received standard cyclosporine (CsA) and mycophenolate mofetil (MMF) as prophylaxis for GVHD. The results showed that the rapid hematopoietic reconstitution was observed in all patients. The median time of ANC ≥ 0.5 × 10(9)/L in both groups were 12 days, the median time of platelet count ≥ 20 × 10(9)/L was 15 days in sm-allo-PBHSCT group and 16 days in sm-allo-PBHSCT + BMT group. The incidence of acute GVHD, acute GVHD of III-IV grade and chronic GVHD in sm-allo-PBHSCT and sm-allo-PBHSCT + BMT groups were 37.1% and 34.2%, 7.89% and 8.06%, 36.11% and 41.38% respectively, there were no statistical differences. The relapse rates were similar in two groups (sm-allo-PBHSCT 13.16% vs sm-allo-PBHSCT + BMT 12.9%). The 3-year disease-free survivals in sm-allo-PBHSC and sm-allo-PBHSCT + BMT groups were 57.1 ± 8.7% and 61.3 ± 6.4% respectively (p = 0.852). The 2-year overall survival of high-risk patients was 41.4 ± 12.8% in sm-allo-PBHSCT group, while 60.9 ± 9.6% in sm-allo-PBHSCT + BMT group (p = 0.071). It is concluded that the rhG-CSF mobilized sibling matched allo-PBHSCT + BMT is superior to the rhG-CSF mobilized sibling matched allo-PBHSCT in increasing the overall survival of high-risk hematologic malignancies.

This study developed a novel approach of targeting malignant glioma with pMAGE-A1278-286-specific cytotoxic T lymphocytes (CTLs) induced from the peripheral blood mononuclear cells of healthy donors by multiple stimulations with human leukocyte antigen (HLA)-A2-restricted pMAGE-A1278-286 peptide-pulsed dentritic cells. Cytotoxic assays were performed by the colorimetric CytoTox 96 assay to analyze cytotoxic activity of the induced CTLs against various target cells. The induced CTLs showed approximately 45% specific lysis against T2pMAGE-A 1278-286 (pMAGE-A 1278-286 peptide pulsed T2 cells) and U251 (HLA-A2+, MAGE-A 1 +)at an effector:target ratio of 40:1, and approximately 5% cytolysis against T2pHIV, A172 (HLA-A2,MAGE-AI+), K562 and T2 cells without being pulsed with peptide at any effector:target ratio. The specific killing activity of the induced CTLs against T2pMAGE-A1278-286 and U251 was much more obvious than in any other control group (P＜0.05). The cytotoxic activity against the T2pMAGE-A1278-286 and U251 was significantly eliminated by anti-HLA class I mAb W6/32.These results suggest that pMAGE-A1278-286 epitope may serve as a surrogate tumor antigen target of specific immunotherapy for treating HLA-A2 patients with malignant glioma.
