Septic shock is the most serious stage of sepsis and the main cause of the high mortality.So far,the scientists have paid more attentions on biomarkers for the early diagnosis and therapy monitoring of septic shock.As a kind of acute phase proteins, heparin-binding protein (HBP)has functions with increasing vascular permeability, sterilization, chemotaxis and regulating cell apoptosis.When the level of plasma HBP is high, it suggests that the patient has severe sepsis with edema and vascular collapse and can beapplied as a valuable biomarker for early diagnosis and therapy monitoring of septic shock.This review focuses on common inflammatory biomarkers for clinical application of sepsis, as well the structure and function of HBP and its clinical application of septic shock.

Objective To detect the expression of type Ⅰ collagen, type Ⅲ collagen, prolyl-4-hydroxylases (PH4) and matrix metalloproteinase 1 (MMP-1) in sacral ligament fibroblasts under stress, to understand the collagen synthesis and metabolism in stress situations change. Methods Eight patients who underwent abdominal hysterectomy for uterine benign disease were enrolled in this study. Primary sacral ligament fibroblasts were isolated by explant. After mechanical loading, gene expression of type Ⅰ , Ⅲ collagen, PH4 and MMP-1 were measured. Results Stress of 8% continuing for 24 hours, collagen Ⅰ (1. 13 ± 0.24), collagen Ⅲ (1.05 ± 0. 31) mRNA expression and PH4 expression (1.11 ± 0. 31) compared with static groups (1) showed increasing trends;when the stress were 4% and 12%, collagen Ⅰ (0. 86 ± 0. 26 and 0. 85 ± 0. 25), collagen Ⅲ showed increasing trends (0. 74 ± 0. 29 and 0. 83 ± 0. 38) mRNA expression were decreased. After removal of the stress, in the stress of 4% for 1 hour, collagen Ⅰ (0.79±0.40, 0.97±0.24 and 1.46 ±0.75), collagen Ⅲ (0.86±0.40, 0.99±0.60 and 1.59±0.82) and PH4 (1.11 ±0. 51, 1.17 ±0. 54 and 1.37 ±0. 39) mRNA expression increased gradually. In 8% stress group, collagen Ⅰ mRNA expression (1.16 ± 0. 62, 1.01 ± 0. 51 and 1.05 ± 0. 80) reached the peak in day 1, and collagen Ⅲ (0.99 ±0.69, 1.59 ±0.55 and 1.03 ±0.91) and PH4 (1.05 ±0.31, 1.07 ±0. 80 and 0. 85 ±0. 31) mRNA expression reached the peak in day 2, then decreased. 4% and 8% of the stress with time after the change, MMP-1 mRNA expression have peaked at day 1. Conclusions Moderate stress could contribute to pelvic floor collagen synthesis, too much or too little stress is not conducive to the synthesis of collagen. Collagen Ⅰ and collagen Ⅲ on the stress response may be different, the former have faster reaction than the latter. PH4 were involved in the synthesis of collagen, while MMP-1 may play a role in collagen degradation.

Lots of studies have identified the relationship between hyperuricemia and cardiovascular diseases. Many factors affect the metabolism of uric acid, such as diet, drug, internal environment of organism, etc. However, the relationship between hyperuricemia and cardiovascular diseases is not quite clear. In this review, we present recently published data about the association between hyperuricemia and selected cardiovascular diseases.

Objective To explore the treatment effect of Zuogui pill (ZGP) on immune premature ovarian failure rats.Methods Female mice model of POF was established by multiple sites subcutaneous injection of zona pellucida 3,and treated with different dosage ZGP (low, middle and high),with prednisone and diaethylstilbestrol as positive control. We detecteed apoptosis rate of granulosa and oocyte of murine ovaries by tunel method and observd the change of sexual cycle and weight. Results Compared with the control group,the weight of model group rat in the third to eighth weeks was significant difference (P

Human proximal tubule epithelial cell line,HK-2 cells,were cultured with various concentrations of insulin for 48 h.Human urate transporter (hUAT) mRNA was detected by realtime quantitative PCR.hUAT mRNA levels were down-regulated by insulin (5,25,125,500 μIU/ml)in a dose-dependent manner (relative expression median were 0.95,0.40,0.24,and 0.23).In vitro,the expression of hUAT mRNA in HK-2 cells is associated with the concentration of insulin.

BACKGROUND: The repair of periodontal tissue is dependent on the number and proliferation and differentiation abilities of periodontal ligament (PDL) cells. PDL cells have the potentiality of multi-directional differentiation such as cementoblast,osteoblast and fibroblast to fonn cement, alveolar bone and periodontal ligament and finally achieve periodontal tissue regeneration.OBJECTIVE:To observe the effects of Shuanghuangbu extract on the proliferation and differentiation of PDL cells.DESIGN:Observation trail.SETTING:Central Laboratory of Wuxi Third People's Hospital. MATERIALS: Periodontal tissue was provided voluntarily by the healthy young patients with deformity correction, and golden thread,skullcap,and rhizoma drynariae by the National Institute for the Control of Pharmaceutical and Biological Products.METHODS: The experiment was conducted in the Central Laboratory of Wuxi Third People's Hospital from July to October 2003.The crushed golden thread.skullcap,and rhizoma drynariae were mixed with distilled water at ratio of 1:10 (m:V),and refluxed in boiling water for 5 hours.The extract was collected,and after colation,the residue was refluxed in boiling water for another 3 hours. Both extract was blended, rotary evaporated and condensed, finally the liquid extract of 3 kg/L was obtained.There were 8 groups in the study including golden thread group, skullcap group,rhizoma drynariae group,golden thread plus skullcap group,golden thread plus rhizoma drynariae group, skullcap plus rhizoma drynariae group, Shuanghuangbu group and control group. PDL cells were cultured/n vitro assisted with Shuanghuangbu.The proliferation of cells was detected with MTT method and the ratio of collagen content in total protein was evaluated with hydroxyproline (HP).MAIN OUTCOME MEASURES:A value of proliferated PDL cells and the proportion of collagen protein in total protein.RESULTS:①Proliferation of PDL cells:Except golden thread group,all Chinese medicine promoted the proliferation of PDL cells significantly compared with control group (P<0.05). The A value of Shuanghuangbu group was significantly increased.A value was increased with time and reached the peak on day 5.There were significant differences among each group at different time (P<0.05).②Ratio of collagen content in total protein:Except golden thread group,the percentage was significantly increased by other Chinese medicines compared with control group (P<0.05), especially Shuanghuangbu. The percentage was increased with time and reached the peak on day 5. There were significant differences among each group at different time (P<0.05). CONCLUSION:The findings suggest that as a traditional Chinese herb,Shuanghuangbu can significantly stimulate the proliferation and differentiation of PDL cells.and increase the proportion of collagen content in total protein.It may act as an ideal Chinese medicine helper factor for the regeneration of PDL cells.

Objective To compare the image quality between large dose smart tracking technique and low dose test bolus technique for gem spectral CT pulmonary angiography(CTPA).Methods A total of 106 cases with suspected pulmonary embolism were divided into two groups.Group A(54 cases)was carried out with large dose smart tracking technique.Group B(52 cases)was carried out with low dose test bolus technique.We compared the image quality between the two groups.Results There were significant differences in the CT value of the right pulmonary artery and the content of iodine in the lower lobe of the right pulmonary artery of two groups(P<0.01).There was significant difference of image quality between the two groups(P<0.05).The rate of excellent or good image quality in group A was higher than that in group B,and the difference was statistically significant(P<0.05).Conclusion Large dose smart tracking technique can track the artifacts of pulmonary artery imaging with less artifacts and uniform vascular fixation.The image quality of pulmonary artery imaging is better than that of small dose contrast agent.
