From aspects of etiology, pathogenesis, treatment and commonly used prescriptions and herbs, this paper expounded traditional Chinese medicine (TCM) theories on cancer. Compound factors such as external evil invasion, diet damage and emotional disorders were causes of cancer in TCM theories. Clinically, TCM emphasized on expelling external evil as an important part in cancer treatment. However, characteristics of different diseases should be differentiated. Great attention should be paid to strengthening the body resistance. Generally speaking, ancient TCM doctors would used tonification herbs together with toxic herbs to benefitqi andyin as well as to promote blood circulation to remove blood stasis. Thus, the deficiency and excess were both considered. And the visible masses can be reduced from all-around and multi-level. This article suggested that TCM theories had great meaning of guidance in cancer treatment for current clinical oncologists.

Objective:To explore the enhanced sensitization to chemotherapeutic agent paclitaxel-induced apoptotic effect on p185-overexpressing human malignant breast cancer cell lines SKBr3 by anti-p185c-erbB-2/neu engineered antibody treatment and to study its emerging mechanism.Methods:The proliferative inhibitory effect was assessed by MTS assay; Cells stained with AnnexinV-FITC and PI were used to qualify the apoptotic cell number by FACS(Fluorescence-activated cell sorting) analysis; Phosphorylation of Ser473 AKt and p65 NF-?B subunit were determined by Western blot; NF-?B-DNA binding activity was demonstrated by EMSA(Electrophoretic mobility shift assay).Results:Anti-p185c-erbB-2/neu engineered antibody rendered SKBr3 cells more susceptible to paclitaxel-induced proliferative inhibition, which further attributed to apoptotic induction; Furthermore, combination of the engineered antibody and paclitaxel also showed effective suppression of AKt/NF-?B pathway in SKBr3 cells.Conclusion:The aggressiveness of AKt/NF-?B pathway was partly attributed to its resistance to paclitaxel-induced apoptosis. Anti-p185c-erbB-2/neu engineered antibody plus paclitaxel combination rendered p185-overexpressing human malignant breast cancer cells SKBr3 more susceptible to paclitaxel-induced apoptosis by efficient suppression of AKt/NF-?B pathway.

The influence of acute and intermittent hypoxia on respiratory mechanics in the range of tidal volume of adult rabbits was studied. All is based on the assumption that the tissue structure of lung constitutes a conservative mechanical system and hence that pressure(P)-volume(V)hysteresis is primarily a result of surface tension(r)-surface area(s)hysteresis. It was found that the lung compliance of rabbits to acute hypoxia was decreased and respiratory work increased. Compared to control group (3.5?1.1mm),the working limbs of P-V loops of acute hypoxic rabbits increased by 49% (5.2?0.6mm). Such changes could be corrected in part by appropriate intermittent hypoxia, the length of working limbs of 5-day adaptation rabbits was 4.2?1.1(P

MicroRNA (miRNA) is a class of endogenous non-coding RNA which found in eukaryotes and has regulatory function.Its size is about 20 to 25 nucleotides.Recent studies found that miRNA is closly related to the EBV,LMP1,signal transduction pathway,tumor-associated gene network,cell mitosis,tumor angiogenesis,tumor invasion and metastasis of nasopharyngeal.Therefore,studing the relationship between miRNA and nasopharyngeal will help to deepen the understanding of its pathogenesis,and also will provide new inspiration and basis for clinical diagnosis and treatment.

Objective To investigate the effect of Tianqi Jiangtang capsules combined with metformin on blood viscosity, cognitive disorder in elderly patients with type 2 diabetes mellitus complicated with cerebral microvascular lesions.Methods 76 patients with type 2 diabetes mellitus complicated with cerebral microvascular lesions were divided into the observation group and the control group according to odd and even numbers, 38 cases in each group.The observation group were given Tianqi Jiangtang capsules combined with metformin while the control group were received metformin alone.The clinical curative effect, adverse reactions were compared between the two groups.The total score of TCM symptoms, blood glucose, blood lipid, high-sensitivity C reactive protein(hs-CRP), hemorheology and Mini Mental State Examination(MMSE)scores were determined before and after treatment.Results The total effective rate in the observation group(89.47%)was significantly higher than that in the control group(71.05%)(P< 0.05);After treatment, the total score of TCM symptoms, FPG, 2 h PG, hs-CRP, TC, TG, LDL-C, whole blood viscosity at high shear, whole blood viscosity at low shear, plasma viscosity and hematocrit were significantly lower than those before treatment, while MMSE scores were significantly higher(P< 0.05), and the above indexes in the observation group after treatment were significantly better than those in the control group(P< 0.05).There were no significant adverse reactions in the 2 groups.Conclusion Tianqi Jiangtang Capsules combined with metformin is safe and effective in the treatment of elderly patients with type 2 diabetes mellitus complicated with cerebral microvascular lesions.It can significantly improve lipid metabolism and hemorheology, reduce blood viscosity, and alleviate cognitive disorder.

Objective To study the effect of continuous passive motion (CPM) on hemiplegic patients with shoulder pain.Methods Forty-four patients were divided into a treatment and a control group.Routine stroke treatment was given to the patients in the control group,and CPM was added for patients in the treatment group.A visual analogue scale for pain (VAS) ,Fugl-Meyer(FM) upper extremity motor scale and functional independence measure (FIM) were used to evaluate the results.Results The VAS,FM and FIM scores of both groups improved after treatment,but the VAS results among the treatment group were significantly better than in the control group. Conclusion CPM can be a good treatment for hemiplegie patients with shoulder pain.

Objective To investigate the value of 18F-FDG SUVmax in gastric cancer diagnosis with coincidence imaging.Methods The coincidence imaging was performed in 92 patients with gastric diseases (60 males,32 females,age 65 (32-85) years; 78 malignant cases,14 benign cases).The malignant cases included 3 remnant gastric cancers and 75 primary gastric cancers (staging: 4 of Tis,13 of T1,9 of T2,33 of T3,11 of T4 and 5 without surgery).The well-,moderately-and poorly-differentiated adenocarcinomas were 22,15 and 28,respectively.Images were analyzed retrospectively with visual method and 18F-FDG SUVmax,and the diagnostic results were compared with the histopathological findings.The ROC curve was used to analyze the SUVmax.The Pearson's correlation analysis was performed to evaluate the relationship between SUVmax and tumor size.The Wilcoxon rank sum test was applied to determine the difference of SUVmax between early and advanced gastric cancers.The Kruskal-Wallis test was used to analyze the difference of SUVmax in various types of differentiated adenocarcinoma.Results No matter visual method or SUVmax was used,the sensitivity,specificity and accuracy of coincidence imaging in diagnosis of gastric cancer were 64.1％(50/78),64.3％(9/14) and 64.1％(59/92),respectively.The AUC of SUVmax was 0.695 and the cut-off value was 0.700.SUVmax Was positively correlated with tumor size significantly(r=0.489,P＜0.001).There was statistically significant difference between SUVmax of Tis-1 and that of T2-4(0.676± 1.288 vs 3.851 ±3.764;Z=-3.754,P＜0.001).However,there was no statistically significant difference among SUVmax of various grades of differentiated adenocarcinoma(2.805±4.008,3.447±2.365,3.413± 3.737 ; x2 =2.459,P＞ 0.05).Conclusions SUVmax provides more information than visual method in assessing gastric cancer with 18F-FDG coincidence imaging.Appropriate cut-off value of SUV is necessary for improvement of the diagnostic efficiency.Relationships between SUV and pathological T stage,histopathological types and differentiation degree need further investigation.

Objective To prepare an antiserum of human putative magnesium transporter protein (HPT protein) to study its biological effects on the drug resistance of gastric cancer cell by observing its expression level. Methods The cDNA encoding HPT protein was cloned and sequenced. Prokaryotic expression vector was constructed and HPT protein fused with histidine tag was expressed. Mice were immunized with the polyacrylamide gel particles containing the fusion protein, and the antisera of them were detected for antibody activity by Western blot. Using the antiserum, HPT protein expression level was assessed in different gastric cancer cell line. Results The sequence of cloned cDNA fragment was consistent with that of HPT. After BL21/pRSETB bacterium was induced with IPTG, a new protein band with a relative molecular weight of 55kD was showed on SDS PAGE profile, and further proved to be fusion protein with histidine tag by Western blot. The antiserum of immunized mice only recognized a unique protein band with a relative molecular weight of 50kD. HPT protein expression level in SGC7901/ADR was higher than in SGC7901. Conclusion The antiserum of HPT protein was successfully prepared, and HPT was found to probably take part in the gastric cancer cell MDR
