The microstructure of cationic cyclopeptide (TD-34) treated Caco-2 cell membrane was observed, and we discussed the relationship between membrane structure and insulin transmembrane permeability. Atomic force microscope (AFM) was used to observe living cell membrane in air condition and tapping mode. Results showed that the surface of Caco-2 cell membrane treated with TD-34 lost its smoothness and nearly doubled its roughness. Apparent permeability coefficients (P(app)) of insulin in Caco-2 cell monolayers increased 2.5 times. In conclusion, AFM can be used to observe microstructure of cationic cyclopeptide treated cell membrane and cationic cyclopeptide enhanced insulin delivery across Caco-2 cell membrane by increasing membrane fluidity.

Objective To report the functional reconstruction and rehabilitation for a patient who under- went allograft for both of his forearms and hands.Methods One male patient underwent allograft for both of his forearms and hands in October 2002 in our department to reconstruct his hand functions.The allografted hands were intervened with an integrated rehabilitation program,which involved administration of immunosuppressants,post- operative monitoring,postoperative functional training,massage,physiotherapy,orthosis,performance training, sensation training,secondary operation and mental rehabilitation.The patient was followed up for 4 years.Results The forearms and hands of the patient were in good shape and regained nearly normal sensation.The distance of two-point-discrimination was 2.5 cm to 4.0cm.The TAM (total active motion) of fingers was fine.The patient could look after himself well and were healthy in psychology.Conclusion An integrated rehabilitation program can yield satisfactory results in the management of allografted forearms and hands.

Objective To analyze the prevalence of peripheral arterial disease (PAD) in type 2 diabetic patients and its association with traditional and non-traditional risk factors. Methods A total of 420 type 2 diabetic patients with duration exceeding 1 year and without acute myocardial infarction, unstable angina,and infection were evaluated. PAD was diagnosed by ankle-brachial index ≤0.90. Risk factors included age, gender, body mass index, smoking, hypertension, diabetes duration,glycated hemoglobin A[C ( HbA_1C ), uric acid, triglyceride, total cholesterol, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol(HDL-C),high sensitive C reactive protein(hs-CRP),fibrinogen,and urinary albumin excretion rate (UAER). Results The prevalence rate of PAD was 16.4%(69/420). Older age, longer diabetes duration,lower HDL-C, higher UAER, hs-CRP and fibrinogen were associated with PAD. Multiple Logistic regression revealed that only age, UAER, hs-CRP and fibrinogen levels were independent risk factors. The prevalence rate of PAD was 4.7%(2/43), 12.9%(27/209) and 23.8%(40/168) in patients of less than 50 years old,50-70 years old and more than 70 years old, and was 7.9%( 14/177),9.3%( 11/118) and 35.2% (44/125) in different hs-CRP group (hs-CRP < 1 mg/L,l-3 mg/L, >3 mg/L), and was 9.7% (30/310) ,34.4%(33/96) and 42.9%(6/14) in normoalbuminuria, microalbuminuria and macroalbuminuria, and was 12.1%(43/356) and 40.6%(26/64) in different fibrinogen levels group (≤4 g/L and > 4 g/L). Conclusions The prevalence rate of PAD is higher in type 2 diabetic patients. Non-traditional cardiovascular risk factors may be involved in the development of PAD.

Sepsis is an infection induced systemic inflammatory response syndrome and is a major cause of morbidity as well as mortality in intensive care units. A growing body of evidence suggests that the activation of a proinflammatory cascade is responsible for the development of immune dysfunction, susceptibility to severe sepsis and septic shock. The present theories of sepsis as a dysregulated inflammatory response and immune function, as manifested by excessive release of inflammatory mediators such as high mobility group box 1 protein (HMGB1), are supported by increasing studies employing animal models and clinical observations of sepsis. HMGB1, originally described as a DNA-binding protein and released passively by necrotic cells and actively by macrophages/monocytes, has been discovered to be one of essential cytokines that mediates the response to infection, injury and inflammation. A growing number of studies still focus on the inflammation-regulatory function and its contribution to infectious and inflammatory disorders, recent data suggest that HMGB1 formation can also markedly influence the host cell-mediated immunity, including T lymphocytes and macrophages. Here we review emerging evidence that support extracellular HMGB1 as a late mediator of septic complications, and discuss the therapeutic potential of several HMGB1-targeting agents in experimental sepsis. In addition, with the development of traditional Chinese medicine in recent years, it has been proven that traditional Chinese herbal materials and their extracts have remarkable effective in treating severe sepsis. In this review, we therefore provide some new concepts of HMGB1-targeted Chinese herbal therapies in sepsis.

Objective To investigate the contribution of hypoxia-inducible factor inhibitor YC-1 to cisplatin chemo-sensitivity to human ovarian cancer cells A2780s in vitro. Methods Ovarian cancer cells were divided into four groups which were treated with saline, YC-1, cisplatin, and YC-1+cisplatin, separately, mRNA of HIF-1αand VEGF in the A2780s cells were detected by real-time fluorescence quantitative PCR by calculating 2-△△CT;the protein were detected by Western blot, to evaluate the change of hypoxia and angiogenesis capabilities under the ovarian cancer microenvironment. Results Compared with the control group, mRNA and protein of HIF-1αand VEGF expressed less in the group of YC-1, cisplatin and YC-1+cisplatin;while, those in the group of YC-1+cisplatin were lower than the monotherapy (P<0. 05), but no significant difference was detected between the YC-1 and cisplatin groups, and the expression of HIF-1αand VEGF mRNA were positively related(r=0. 830 5)in each group. Conclusion YC-1 exerts the antitumor effect and may contribute to sensitivity to cisplatin in the therapy of ovarian cancer.

Objective To investigate the correlation between pelvic organ prolapse quantitation (POP-Q) indication points and the incidence of occult stress urinary incontinence (OSUI) and its impact on prognosis. Methods Retrospective study medical records of 93 patients with pelvic organ prolapse (POP) staged atⅢ-Ⅳ, of which underwent pelvic reconstruction operations with Prolift system from Jan. 2007 to Sept. 2012. None of these patients had clinical manifestations of stress urinary incontinence (SUI) before surgery, and in which 44 patients were included in study group (POP complicated with OSUI) because they were identified with OSUI, another 49 patients as control group (simple POP). Follow-up and collecting datas including POP-Q, stress test, urodynamic recordings, incidence of de novo SUI, statistic analyzing by logistic regression and receiver operating characteristic curve (ROC). Results (1) The study group had a much higher incidence of 30%(13/44) on de novo SUI than that of control group (4%, 2/49;P<0.01). (2) Vaginal delivery (OR=5.327, 95%CI:1.120-25.347), constipation (OR=5.789, 95%CI:1.492-22.459), preoperative OSUI (OR=13.695, 95%CI:2.980-62.944), anterior vaginal wall prolapse (OR=6.115, 95%CI:1.231-30.379) were identified as dependent risk factors for de novo SUI by logistic regression analysis. (3) For POP patients that complicated with OSUI, we chose a cutoff value of +1.5 cm for Aa point as the threshold to predicting incidence of de novo SUI according to ROC curve, area under the curve (AUC) was 0.889 (P<0.05), the sensitivity reached 88.9%and specificity was 73.9%. According to ROC curve of Ba point, a cutoff value of+2.5 cm was chosen as the threshold to predicting incidence of de novo SUI post-operation, it had a sensitivity of 66.7% and specificity of 82.6%, AUC was 0.766 (P<0.05). Conclusions Pre-operative OSUI is a dependent risk factor of de novo SUI for advanced POP patients. Aa and Ba points are correlated with preoperative OSUI, and it is worthy to be considered as a risk predictor on forecasting the incidence of de novo SUI post pelvic reconstruction surgery.

Objective To analyse the high-dose dexamethasone suppression test(HDDST)-related differences in the clinical and biochemical features of the patients with Cushing's disease Methods Cases were drawn from 60 consecutive patients with Cushing's disease,who were then divided into two groups according to the response to the HDDST.The clinical and biochemical features between two groups were compared.Results(1) Of the 60 patients with Cushing's disease,23.3%(14/60)of patients(group A)did not yield results of suppression with the HDDST,and the others(group B)did.No difference was found in the age[(33.8?10.4 vs 36.2?11.2)years]and duration of illness[(2.1?1.6 vs 3.9?3.1)years]between two groups.(2)In clinical features,the patients in group A were more likely to have edema of lower limbs(64.3% vs 32.6%),hypokalemia (71.4% vs 28.3%),secondary diabetes(57.1% vs 26.1%)and purple striae(85.7% vs 54.3%,all P
