Objective:To investigate the expression of microRNA-324-5p (miR-324-5p) and transcription factor forkhead box C1 (FOXC1) in glioma and their relationship with the prognosis of patients.Methods:From March 2012 to March 2015, a total of 72 cases of glioma tissues were collected from glioma patients who were admitted to Chongqing Hygeia Tumor Hospital and the People's Hospital of Nanchuan in Chongqing, and 28 cases of normal human brain tissues resected in craniocerebral surgery were also collected. The expressions of miR-324-5p and FOXC1 mRNA were detected by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR), and the expression of FOXC1 protein was detected by immunohistochemistry. Pearson method was used to analyze the correlation between the expressions of miR-324-5p and FOXC1 in glioma tissues; Kaplan-Meier method was used to analyze the survival of patients with glioma; Cox regression analysis was used to analyze the risk factors affecting the prognosis of patients with glioma.Results:FOXC1 protein was mainly located in the cytoplasm of glioma, and its positive expression rate in glioma tissues was 81.94% (59/72), which was significantly higher than that in normal brain tissues [17.86% (5/28)], and the difference was statistically significant ( χ2 = 35.938, P<0.01). Compared with normal brain tissues, the expression of miR-324-5p was down-regulated in glioma tissues (0.62±0.19 vs. 0.98±0.02, t = 9.974, P < 0.05), and the expression of FOXC1 mRNA was up-regulated (1.41±0.29 vs. 0.99±0.02, t = 7.633, P < 0.05). The expressions of miR-324-5p and FOXC1 protein were correlated with the number of primary lesions, differentiation degree, TNM stage and lymph node metastasis of glioma (all P<0.05). Pearson analysis showed that the expressions of miR-324-5p and FOXC1 mRNA were negatively correlated ( r = -0.550, P<0.01). The 5-year overall survival rate of patients in miR-324-5p high-expression group was significantly higher than that of patients in miR-324-5p low-expression group (45.71% vs. 24.33%, χ2 = 6.531, P = 0.011), and the 5-year overall survival rate of patients in FOXC1 protein high-expression group was significantly lower than that of patients in FOXC1 protein low-expression group (30.41% vs. 42.34%, χ2 = 3.631, P = 0.047). Multivariate Cox regression analysis showed that low differentiation, TNM stage Ⅲ-Ⅳ, lymph node metastasis, low expression of miR-324-5p and high expression of FOXC1 protein were independent risk factors for prognosis of glioma patients (all P < 0.05). Conclusions:The expression of miR-324-5p is low and the expression of FOXC1 is high in glioma. They may be involved in the regulation of tumor differentiation and metastasis, and related to the poor prognosis of patients. They may be potential therapeutic targets for glioma.

OBJECTIVETo study the correlation between TCM syndrome type and liver tissue pathological changes in patients with chronic hepatitis B (CHB) in order to provide evidence for syndrome differentiation.

METHODSSyndrome typing as well as liver pathological grading and staging of liver biopsy were performed on 260 patients with CHB, then the relationship between them was analyzed.

RESULTS(1) The grade of liver inflammation was mainly G1 and G2 in patients of Gan-qi stagnation and Pi-deficiency type (type 1); G2 in patients of inner damp-heat retention type (type II); G3 in patients of Gan-Shen yin-deficiency type (type lII) and Pi-Shen yang-deficiency type (type IV); while G4 occurred mainly in patients of blood stasis blocking collateral type (type V), showing significant difference as compared with other syndrome types. (2) The liver pathological stage in patients of type I and II was mainly S1 and S2, while S3 and S4 occurred mainly in patients of type III and type IV. (3) The pathological change was mainly G3-G4 and S3-S4 in blood stasis syndrome, while it was mainly G1-G2 and S1-S2 in non-blood stasis syndrome.

CONCLUSIONThe TCM syndrome type is correlated with liver tissue pathological change to certain extent, among them, syndrome with or without blood stasis showed the closest correlation. The syndrome type of CHB patients developed, along with the aggravating of liver pathological injury, from sthenia to asthenia, from qi to blood, and finally to the blood stasis blocking collateral. So the treatment should be lay stress on activating blood circulation to remove stasis, and be implemented by 3 stages.

This study was conducted to investigate the paclitaxel loaded by hydrazone bonds in poly(ethylene glycol)-poly(caprolactone) micelles (mPEG-PCL-PTX) on proliferation and apoptosis of human lung cancer A549 cells and its possible mechanisms of anti-tumor activity. The cell proliferation was measured with MTT assay. Flow cytometry were used to analyze the cell cycle. The cell apoptosis was analyzed using Hoechst/P staining. The expression levels of apoptotic genes expression in the mitochondrial apoptosis pathway were detected by RT-PCR and Western blotting, respectively. The mPEG-PCL-PTX could inhibit the proliferation of A549 cells and promote the apoptosis. The Bax, caspase-3 protein expression were increased while Bcl-2 protein expression was decreased in A549 cells. Results showed that the polymer containing hydrazone bond is non-toxic in vitro, the mPEG-PCL-PTX micelles can inhibit the proliferation and induce the apoptosis of A549 cells.

OBJECTIVETo explore the efficacy and feasibility of dog days moxibustion plaster therapy in treatment of allergic rhinitis of different patterns/syndromes.

METHODSAllergic rhinitis of lung deficiency and invasion of cold, spleen qi deficiency and kidney yang deficiency, 56 patients for each pattern/syndrome were randomized into a plaster therapy group and a nasal spray group, 28 cases in each one. In the plaster therapy group, according to the pattern/syndrome differentiation, with literature retrieval method, 3 acupoints of high frequency utility in clinic were selected as one group in acupoint plaster therapy. For lung deficiency and invasion of cold pattern/syndrome, Feishu (BL 13), Fengmen (BL 12) and Hegu (LI 4) were selected. For spleen qi deficiency pattern/syndrome, Pishu (BL 21), Zusanli (ST 36) and Dazhui (GV 14) were selected. For kidney yang deficiency pattern/ syndrome, Shenshu (BL 23), Dingchuan (EX-B 1) and Bailao (EX-HN 15) were selected. Separately, on July 13, 2013, July 23, 2013, August 2, 2013 and August 12, 2013, the aucpoint plaster therapy was applied, 2 to 4 h (1 to 2 h for children) each time. In the nasal spray group, beclometasone dipropionate aqueous nasal spray, 2 presses one nostril each time, 2 to 3 times a day, continuously for 4 weeks. The symptom score and efficacy were compared before and after treatment in the patients of the two groups.

RESULTSThe symptom scores of 3 patterns/syndromes were all apparently improved after treatment as compared with those before treatment in the patients of the two groups (all P<0.05), and the result in the plaster therapy group was better than that of the nasal spray group (P<0.05, P<0.01). For lung deficiency and invasion of cold pattern/syndrome, the total effective rate was 87.3% (20/24) in the plaster therapy group, better than 84.6% (22/26) in the nasal spray group (P<0.05). For spleen qi deficiency pattern/syndrome, the total effective rate was 83.3% (20/24) in the plaster therapy group, obviously better than 76.9% (22/26) in the nasal spray group (P<0.05). For kidney yang deficiency pattern/syndrome, the total effective rate was 79.2% (19/24) in the plaster therapy group, better than 76.9% (22/26) in the nasal spray group (P<0.05).

CONCLUSIONThe dog days moxibustion plaster therapy achieves definite efficacy on allergic rhinitis at the acupoints selected based on the differentiation of different patterns/syndromes and the efficacy is better than beclometasone dipropionate aqueous nasal spray.

Intravenous immunoglobulin (IVIG) is used to treat various diseases and has anticancer effects that suppress metastases in animal models of sarcoma and melanoma. However, these effects have been observed in a limited number of clinical cases. We report the case of a patient with metastatic breast cancer in which long-term IVIG treatment stopped disease progression in the absence of salvage chemotherapy. The patient was treated with IVIG for the treatment of immune thrombocytopenia. Surprisingly, the lung and brain metastases were stabilized, and the patient achieved a progression-free interval of 29 months. More cases are needed to investigate and confirm the efficacy of IVIG in solid tumors in the future.
