Objective To find a grading method for assisting in evaluating hypoxia degree of patients with pulmonary heart disease non-invasively. Methods To design a quantitative method to score degree of hypoxia of 67 patients with pulmonary heart disease by using acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) as a frame and to make comparative analysis between the grading result and artery blood gas to find the correlation. Results There was a negative correlation between evaluation mark and pH、PaO2、SaO2 and a positive correlation between the evaluation mark and PaCO2, according to statistics. Conclusions Although the grading table of hypoxia evaluation can not substitute blood gas analysis, acting as a non-invasive method to assist in evaluating the hypoxia degree of patients with pulmonary heart disease, it can not only relieve patients' repeated punctuation pain, but also achieve the goal of estimating hypoxia.Consequently the non-invasive method to evaluate hypoxia is of clinical value.

Gastric cancer is one of the most common malignancies in the digestive system.Most of the patients with gastric cancer have advanced disease at the time of diagnosis.Chemotherapy is still the mainstay of treatment for advanced gastric cancer,but efficacy of chemotherapy was modest.Molecular targeted therapies have emerged as a novel approach to the treatment of both hematological and solid tumors in recent years.The understanding of molecular biological mechanisms underlying the formation,progression and metastasis in advanced gastric cancer has enabled us to use the new approach to treat this disease in clinical practice.These therapeutic strategies include targeting EGFR signal transduction pathway,anti-angiogenesis,targeting NF-?B signal transduction pathway and cyclin-dependent kinase inhibitors.In this review,a brief introduction of the current status of the molecular targeted therapies in the treatment of gastric cancer was presented.Bevacizumab,anti-VEGF monoclonal antibody targeting the angiogenesis pathway has been approved for the treatment of colorectal cancer by FDA,has been reported to show effectiveness in metastatic gastric cancer when combined with cytotoxic agents.Inhibition of NF-?B signal transduction pathway such as PS-341(proteasome inhibitor,bortezomib) approved for the treatment of refractory or recurrent multiple myeloma by FDA has also been used to combine with chemotherapy for gastric cancer.There are also encouraging reports on the combination of standard chemotherapy with Cetuximab,Matuzumab,Gefitinib,Erlotinib and Trastuzumab which target the EGFR and HER2 signal transduction pathways.Flavopiridol is a cyclin-dependent kinase inhibitor with low molecullar weight that aims at the regulatory process of the cell cycle but this needs further clinical trial.

Objective To investigate the relation of DNA content and SPF to the clinicopathological characteristic in lung cancer.Methods Fresh specimens taken from 56 patients with lung cancer and 36 patients with non-malignant pulmonary lesions were measured for DNA index(DI),S-phase fraction(SPF) by using FACSCalibur 4200 flow cytometry.Results ① DNA index(DI) of lung cancer was 1.18?0.33,0.99?0.07 in lung cancer and non-malignant groups,respectively.The percentage of heteroploid was 78.6% in lung cancer,(5.6%) in non-malignant.DI and the positive rate of heteroploid were significantly higher in lung cancer groups than that in non-malignant group(P0.05);③ It was demonstrated that SPF was significant higher in lung cancer groups than that in non-malignant group. The SPF of heteroploid tumors was higher than that of diploid tumors(P

Objective To investigate the effects of CO 2 pneumoperitoneum during laparoscopic cholecystectomy (LC) on pulmonary functions in chronic pulmonary failure rabbits and their mechanisms. Methods A total of 50 healthy male rabbits ( oryctolagus cuniculus ) were randomly divided into 4 groups: normal control group (N 0: n=5, no pneumoperitoneum), experimental control group (T 0: n=5, no pneumoperitoneum), 10 mmHg experimental group (T 10 : n=20, 10 mmHg pneumoperitoneum) and 15 mmHg experimental group (T 15 : n=20, 15 mmHg pneumoperitoneum). After the successful establishment of emphysema rabbit models, CO 2 pneumoperitoneum was conducted and maintained for 2 hours at the pressure of 10 mmHg (1.33 kPa) and 15 mmHg (2.00 kPa), respectively. Pulmonary functions (total respiratory resistance, central resistance and total airway resistance) of the 4 groups were measured by pulse oscillation technique before and after the pneumoperitoneum, respectively. Results Total respiratory resistance, central resistance and total airway resistance increased after the establishment of emphysema models. And they decreased at the end of pneumoperitoneum compared with those before pneumoperitoneum ( q=17.824, P

Isoelectric focusina Electrophoresis(lFE)was use to detenmine the isoelectric point of main protein composition in Chinese Traditional Medicine (TCM ) either of animal origin Such as (EuPotyPhage sinenses)orfrom fruit or seed of plants (such as the seed of CeIosia urgeatea). Results showed that their IFE bands werealways quite distinct,which can be used to assess their quality and to distinguish them from confusable varieties.

Objective:To explore the protective effect of biochanin A(Bioch A) on lipopolysaccharide(LPS) -induced dopaminergic neurodegeneration. Method:An in vitro model of LPS-induced dopaminergic neurodegeneration was used to investigate the protective effect of Bioch A on dopaminergic neurons against LPS-induced neurotoxicity by measuring [3H] DA uptake and counting TH-immunoreactive cells. Microglia were visualized by staining for the CR3 complement receptor with monoclonal antibody OX-42. The production of nitric oxide(NO) was determined by measuring the accumulated levels of nitrite in the culture supernatant with the Griess reagent,and release of tumor necrosis factor-?(TNF-?) was measured by immunosorbent assay. The production of superoxide was determined by measuring the superoxide dismutase(SOD) -inhibitable reduction of cytochrome C. Results:BiochA dose-dependently attenuated LPS-induced decrease in dopamine(DA) uptake and the number of dopaminergic neurons in rat mesencephalic neuron-glia cultures. BiochA also significantly inhibited LPS-induced activation of microglia and production of TNF-?,NO and superoxide in rat mesencephalic neuron-glia cultures and microglia-enriched cultures. Conclusion:Biochanin A may protect dopaminergic neurons from LPS-induced injury and its effectiveness in inhibiting microglia activation may underlie one of the mechanisms.

Dry eye is the most common ocular surface diseases encountered in the clinic.At present,a system for dry eye diagnosis and treatment has initially been formed in China,but there are still many clinical issues need to be resolved.It is important to improve the definition of dry eye and construct a more rational classification system;pay attention to the epidemiological investigation of dry eye;standardize diagnostic procedures for dry eye;establish the dry eye diagnostic criteria and the correct treatment concept.We propose to develop the clinical guidelines on dry eye classification,diagnostic criteria and treatment principles.
