The suggestion of microcosmic syndrome differentiation is to meet the needs of clinical diagnosis and treatment of traditional Chinese medicine (TCM), the needs of evidence based medicine and the needs of the development of syndrome differentiation in TCM. The possibility of microcosmic syndrome differentiation might be the development of integration of traditional Chinese and Western medicine as well as modern science and technology. Microcosmic syndrome differentiation has its superiority and limitation. There are some problems in developing microcosmic syndrome differentiation, such as lack of standard for syndrome differentiation, contradiction between single microcosmic index and the entirety, non-specificity of the relationship between microcosmic indexes and syndromes, and the influence of disease on microcosmic syndrome differentiation, discrepancy between the essence study of TCM syndromes and the clinical practice. It is suggested that the concept of TCM syndrome is a certain pathological process during the onset and development of disease, composed of some subjective and objective indexes. The objective indexes include the macrocosmic and the microcosmic indexes, the entirety and the part.

Objective To observe the clinical efficacy of Tiao Shen Kai Yu (regulating mind and anti-depression) needling plus mental intervention in treating mild post-stroke depression. Method A total of 100 eligible subjects with mild post-stroke depression were randomized into a control group and an observation group, 50 cases in each group. The two groups were both intervened by basic treatment, while the control group was additionally given mental intervention and the observation group was given Tiao Shen Kai Yu needling plus mental intervention. The two groups were treated once a day, 5 times a week, for 30 d in total. The Self-rating Depression Scale (SDS) and Hamilton Depression Scale (HAMD) were observed before and after the treatment. Result The HAMD scores were both significantly improved in the two groups after the treatment (P<0.01), and the between-group difference was statistically significant (P<0.01). The SDS scores were significantly improved after the treatment in both groups (P<0.01), and the between-group difference was statistically significant (P<0.01). Conclusion Tiao Shen Kai Yu needling plus mental intervention can more effectively improve mild post-stroke depression than single mental intervention.

Hypoxia is a common physiological and pathological stimulus in many human diseases .The cellular oxygen sensors and the following activation of multiple cellular signal transduction pathways involved in hypoxia responses can regulate cell survival as well as respiration , blood circulation , metabolism and so forth .The cell response to hypoxia has a complex diversity .Hypoxia-induc-ible factor ( HIF) pathway in an oxygen dependent manner plays a central role during the hypoxia response .The HIF-independent path-ways are equally important under hypoxic conditions which can maintain the oxygen balance and metabolism balance .

Bibliometrical method was used in this article to analyze the publications in a hospital from 2004 to 2013.Results show that the number of publications increased during 8 years,and the quality has been improved consistently.However,the rate of clinician participation in research and the present of core authors were still on the lower side.Besides,the age structure of core authors is steady and lack of growth.Based on this analysis,we summarized the past experience and explored the strategies of research management.

Hologram is a theory to study the properties and laws of the world under a holographic interaction.Traditional Chinese Medicine(TCM) shares many common fi elds with hologram theory.Although some originally diagnostic folk methods such as Zhejiang.sixian pulse theory,Kunlun?tianyuan pulse theory have been rarely known and have not been widely recognized in modern time,the diagnostic methods of Jiugong pulse and hologram pulse based on the two pulses theories have shown its uniqueness and effectiveness through hundreds of years of clinic practices.Based on holographic principles and holism,a physician can make diagnoses noninvasive,simple and rapid,which is benefi t for inheritance and development of TCM pulse methods.

Objective To explore the value of spectral curve in the differential diagnosis of benign and malignant tumor of the musculoskeletal system.Methods 100 patients with mass of the musculoskeletal system which were found by MRI underwent Dis-covery HD750 Gemstone CT scan ,and the images acquired were processed.Areas with homogenous density which did not contain necrosis,cyst,hemorrhage and calcification were chosen as region of interest(ROI).The optimal Kev on single energy images was selected,then the Kev-CT curve was automatically generated.All 100 patients proved by histological examination were divided into four groups,38 cases were as group A with benign tumor,10 cases as group B with borderline tumor,49 cases as group C with ma-lignant tumor and 3 cases of lipoma(that were analyzed separately since its curve was arc shaped).Average slope rate of every group was calculated according to the formula:K=(HU40keV-HU80keV)/40.Kruskal Wallis test was applied for statistical analysis,P value of less than 0.05 was considered statistical significant.Results The spectral curve of group C was sharply falling type with a mean slope rate of 1.64±1.00,that of group A was gradually falling type with a mean slope rate of 0.75±0.30,and that of group B was 1.34±0.45.The difference of slope rate between group A and C and between A and B were of statistical significance(P<0.05).The spectral curve of 3 lipomas showed arc shaped rising type with a mean slope rate of-2.00.Conclusion Spectral curve is useful in the differential diagnosis of benign and malignant tumor of the musculoskeletal system.Arc shaped curve is a specific sign for tumors containing abundant fat.

Objective High mobility group box 1 (HMGB1) mediates the inflammatory immune response as well as the prolif-eration, differentiation and migration of cells , neverthless, little study has been done on the changes of HMGB 1 expression in hepatoma tissues.The aim of the article was to investigate the changes of HMGB 1 mRNA and protein expression in hepatocellular carcinoma (HCC) tissues. Methods Real-time fluorescence quantitative PCR and Western blotting were applied to detect HMGB 1 mRNA and protein expression in HCC tissues and their paracancerous tissues of 13 cases.Immunofluorescence localization was used to analyze the changes of HMGB1 distribution in hepatic cells . Results The expression of HMGB1 mRNA and protein in HCC tissues (4.01 ±0.81) and (1.37 ±0.34) increased significantly in comparison with those in paracancerous tissues (5.76 ±1.28) and (0.52 ±0.12) ( P<0.01).Nucleo-cytoplasmic translocation of HMGB1 was observed in hepatocarcinoma cells . Conclusion There is increased expression of HMGB1 in HCC tissues, which shows HMGB1 mediates the carcinogenesis of HCC .

Objective To observe the differences of retinal vessel oxygen saturation between diabetic and healthy subjects.Methods Seventy-one diabetic patients and 91 healthy persons were included diabetes group and control group respectively.Oxygen saturation was measured in retinal blood vessels in two groups using retinal Oxymap.The oxygen saturation in retinal arteries and veins about 1.5-3.0 disc-diameter from center of optic disc was analyzed by instrumental software.Results Among 71 cases of diabetics,there was no significant difference in retinal oxygen saturation between male and female,among different ages and duration of disorder (all P ＞ 0.05).The retinal average arteriolar oxygen saturation in diabetes group was higher than that in control group (P =0.00).The diabetes group had the higher arteriolar oxygen saturation in all the quadrants,while only the superior temporal and inferior temporal showed significant difference statistically (all P ＜0.05).The retinal average venous oxygen saturation in diabetes group showed an upward trend although with no significance (P ＞0.05).Venous oxygen saturation in the diabetes group were higher in retinal superior temporal and inferior temporal quadrant and lower in retinal inferior nasal quadrant,there were significant statistical differences (all P ＜ 0.05).The retinal arterio-venous oxygen saturation differences in diabetes group was higher than that in control group,there was significant statistical difference (P =0.00).Conclusion There is significant difference in retinal vessel oxygen saturation between diabetics and healthy subjects.There are different degrees of changes in retinal oxygen saturation among different quadrants,indicating uneven distribution of retinal oxygen metabolism in each quadrant.
