Objective The periacetabular tumor has a low rate of incidence, but its special location poses a challenge to clinical treatment.The aim of this study was to discuss the methods, effects, and complications of surgical treatment of periacetabular tumors. Methods We retrospectively analyzed the clinical data of 36 cases of periacetabular tumor surgically treated in our depart-ment, including 21 males and 15 females, aged 15 to 64 (45.2 ±6.3) years.Among them, there were 8 cases of benign tumor (4 ca-ses of simple bone cyst, 1 case of desmoplastic fibromas, 1 case of osteofibrous dysplasia, and 2 cases of hemangioma) and 28 cases of malignant tumor (5 cases of osteosarcomas, 12 cases of chondrosarcomas, 2 cases of giant cell tumor of the bone, 1 case of malignant chondroblastoma, 2 cases of malignant fibrohistiocytoma, and 5 cases of metastatic tumor of the bone).The benign cases received sim-ple tumor resection plus bone graft and steel plate system internal fixation, while malignant cases underwent reconstruction by combined pedicle screw fixation system with bone cement. Results No patients died perioperatively and controllable complications occurred in 5 cases after operation.All the patients were followed up for 5 to 96 months except for 1 case of benign tumor.None of the benign cases experienced recurrence, and all of them achieved normal hip function.Lung metastases occurred in 10 malignant cases (4 cases of os-teosarcomas and 6 cases of chondrosarcomas) , who died of respiratory failure, and the other 18 remained tumor-free after surgery.Of the 2 patients with malignant fibrohistiocytoma, 1 died 2 years postoperatively and the other survived with tumor.Neither local recur-rence nor lung metastasis was found in the patients with chordoma and malignant chondroblastoma till the end of follow-up.The 5 pa-tients with metastases died within 3 years after operation.At 3 months after surgery, the Harris scores after total hip replacement were >90 in the 7 benign cases, 70-79 in 9 malignant cases, and <70 in the other 19 malignant cases. Conclusion For the treatment of malig-nant tumors, reconstruction by combined pedicle screw fixation system with bone cement does not affect the general daily activities of the pa-tients.Preoperative embolization of the internal iliac artery can reduce bleeding and improve operation safety, and measures should be taken to minimize postoperative complications.

Transcription factor is one of the key factors in the regulation of gene expression at the transcriptional level. It plays an important role in plant growth, active components biosynthesis and response to environmental change. This paper summarized the structure and classification of bHLH transcription factors and elaborated the research progress of bHLH transcription factors which regulate the active components in plants, such as flavonoids, alkaloids, and terpenoids. In addition, the possibility of increasing the concentration of active substances by bHLH in medicinal plants was assessed. The paper emphasized great significance of model plants and multidisciplinary research fields including modern genomics, transcriptomics, metabolomics and bioinformatics, providing the contribution to improve the discovery and function characterization of bHLH transcription factors. Accelerating the research in the mechanism of bHLH transcription factors on the regulation of active components biosynthesis will promote the development of breeding and variety improvement of Chinese medicinal materials, also ease the pressure of resources exhaustion of traditional Chinese medicine home and abroad.

Using methylated pyrroloxicam as a starting material and following the principles of drug design such as bioisosterism and active site binding, we designed and synthesized ten structurally novel target compounds, whose structures were characterized by 1H NMR and MS analysis. The in vitro antitumor activity of these title compounds was evaluated by measuring their inhibitory activity against pancreatic cancer cells Capan-1, leukemia cells L1210, and human liver cancer cells SMMC-7721. The results showed that compound 6f (IC50=4.8±0.5 μmol/L) exhibited good inhibitory activity against Capan-1 pancreatic cancer cells, that compound 6b (IC50=2.6±0.3 μmol/L) showed good inhibitory activity against L1210 leukemia cells, and that compound 6c (IC50=2.1±0.2 μmol/L) displayed good inhibitory activity against SMMC-7721 human liver cancer cells. These preliminary results from the antitumor activity experiments suggest that the introduction of benzothiazine derivatives plays a certain role in enhancing the antitumor activity of this class of compounds.

OBJECTIVETo optimize the ultrasonic extraction condition for flavonoids from Chrysanthemum morifolium.

METHODThe extraction rate of flavonoids optimized condition (ethanol concentration, ultrasonic time, solvent quantity and extraction times) was determined by orthogonal design. UV-Spectrophotometry was used for the determination.

RESULTThe order of factors to affect the flavonoid extraction was ethanol concentration > extraction times > solvent quantity > ultrasonic time.

CONCLUSIONThe optimum ultrasonic extractions were: A2 B2 C3 D3. Compared with traditional extraction, ultraction method can save time, be easy to operate, improve extraction rates and need no heating.

This study was aimed to compare the expression level of eIF4E in patients with leukemia and normal controls, and to explore its role in leukemogenesis. White blood cells were collected in 76 leukemia patients and 10 healthy volunteers. The mRNA and protein expressions of eIF4E were detected by QT-PCR and Western blot in 39 cases of acute myeloid leukemia (AML), 15 cases of chronic myeloid leukemia (CML), 22 cases of acute lymphocytic leukemia (ALL) and 10 healthy volunteers as normal controls. The results demonstrated that compared with normal controls, the absolute expression levels of eIF4E mRNA increased in patients with AML, ALL and CML in blastic phase (P < 0.05), but had no significant change between groups of CML in chronic and accelerated phase although some increasing in group of CML in accelerated phase. The relative expression level of eIF4E mRNA had no significant change in AML, ALL, CML groups except the two subtypes of leukemia M4 and M5. Furthermore, the protein expression level in group of CML in accelerated phase and blastic phase and all acute leukemia patients including AML and ALL were higher than that in normal controls (P < 0.05). It is concluded that although its mRNA relative expressions had no significant change in most leukemia patients, the absolute expression level of eIF4E mRNA and its protein expression is up-regulated in most leukemia patients, which may play an important role in leukemogenesis, so the eIF4E may be a promising target for leukemia therapy and eIF4E-targeted therapy may be an option especially for the relapse and refractory leukemia.

Objective The unbalanced phenotype of pe-ripheral blood monocyte is closely related to the pathological progres-sion of pulmonary fibrosis .The present study was designed to address the dynamic changes of circulating monocyte subsets in the experimen-tal mouse model of pulmonary fibrosis , and explore the relationship of circulating monocyte subsets with pulmonary inflammation and fibro-sis. Methods A total of 100male C 57BL/6J mice were random-ized as control group and a bleomycin A 5 group to be treated with sterile saline and bleomycin A5 at 2 mg/kg, respectively.The mice were sacrificed on day 1, 3, 7, 14, and 21 after treatment.The inflammation score and collagen volume fraction ( CVF) of the lung tissue were obtained by HE and Masson staining .The total number and different types of cells in the bronchoalveolar lavage fluid ( BALF) were counted using the routine method .The mRNA expressions of collagens ⅠandⅢwere determined by real-time PCR, the content of hydroxyproline (HYP) assayed by the chloramine-T method, and the proportions of different monocyte subsets measured by flow cytometry . Results Compared with the saline control , the bleo-mycin A5 group showed significantly increases in the inflammation score at 3 and 7 days ( P<0 .01 ) , CVF at 14 and 21 days ( P<0.01), and the numbers of total cells and macrophages in BALF at 3-21 days, the count of neutrophils granulocytes at 1-3 days (P<0.01), The numbers of neutrophile granulocyles were significant higer than that in control groups on the 1st(9.086 ±1.268 vs 1.108 ±0.229), 3rd(5.551 ±0.511 vs 0.315 ±0.100) and 7th(8.093 ±0.922 vs 0.249 ±0.074)day.The mRNA expressions of collagens ⅠandⅢat 14 and 21 days (P<0.05), the content of HYP at 7-21 days (P<0.01), and the proportion of Ly6Chi mon-ocytes on day 1, which peaked on day 3 (P<0.01) and then decreased from day 14 to 21.The proportion of Ly6Chi monocytes was positively correlated with the inflammation score (P<0.000 1) and CVF of the lung tissue (P=0.001 3). Conclusion In the mouse model of bleomycin A5-induced pulmonary fibrosis, dynamic changes of circulating Ly6Chi and Ly6Clo monocyte subsets occurred in different pathophysiological stages .Compared with the pathological process of inflammatory infiltration , Ly6Chi circulating monocytes displayed a rapid response to tissue injury and inflammation .The increased proportion of Ly6Chi monocyte subsets might be closely re-lated with pulmonary inflammation and fibrosis .
