Objective To investigate the effect of spleen-supplementing and lung-strengthening therapy on patients with chronic obstructive pulmonary disease(COPD)treated by mechanical ventilation and enteral-parenteral nutritional support.Methods Acute exacerbation COPD patients complicated with respiratory failure treated by mechanical ventilation were randomized into group A(n=32)and group B(n=30).The two groups received invasive or non-invasive mechanical ventilation,routine western medicine and enteral-parenteral nutritional support.Group A received oral use of Jianpi Yifei Granules(mainly composed of Radix Ginseng Destillata,Rhizoma Atractylodis Macrocephalae,Poria,Radix Ophiopogonis,Cortex Mori,Radix Astragali)and electroacupuncture(EA)on bilateral acupoints of Zusanli additionally.The treatment lasted 2 weeks.The changes of leg circumference and arm circumference,and serum levels of total protein(TP),albumin(Alb),prealbumin(PAlb)and hemoglobin(Hb)were observed.The outcomes of mortality rate during hospitalization,success rate of removing respiratory machine,time for parenteral nutritional support,time for invasive or non-invasive mechanical ventilation,fee for nutritional support and hospitalization fee in intensive care unit(ICU)were compared in the two groups.The incidences of complications of pneumonia,fungal infection,and upper gastrointestinal hemorrhage were also observed during mechanical ventilation.Results After treatment,serum levels of TP and PAlb were higher in group A than those in group B(P0.05);leg circumference and arm circumference in the two groups increased(P0.05).Time for parenteral nutritional support,time for invasive or non-invasive mechanical ventilation,and fee for nutritional support and hospitalization fee in ICU were lower in group A than those in group B(P

Objective:To study the clinical curative effect and nursing interventions of CBP used in critically ill patients. Methods:critically ill patients were enrolled and given CBP treatment, then randomly divided into given nursing intervention and control group were given usual care. Cardiac function, renal function and treatment related complications were observed. Results:after the treatment, E/A, LVEF, LVEDD, Ccr were higher than that before treatment;Scr, BUN levels were lower than that before treatment;cases of arrhythmia, angina pectoris, hypotension, cardiac packing, hypoxemia and puncture point infection, hematoma of observation group were less than control group. Conclusion:CBP therapy can improve heart function and renal function in critically ill patients and the nursing intervention measures can reduce the occurrence of complications in treatment.

OBJECTIVE:To investigate clinical efficacy and safety of breviscapine combined with vinpocetine in the treatment of acute cerebral infraction. METHODS:A total of 80 patients with acute cerebral infraction were selected from our hospital during Jan. 2014-Dec. 2015,and then divided into observation group and control group according to random number table,with 40 cases in each group. Control group was given Vinpocetine injection 20 mL+0.9％ Sodium chloride injection 250 mL,ivgtt,qd. Observa-tion group was additionally given Breviscapine injection 20 mL+5％ Glucose injection 250 mL,ivgtt,qd,at intervals of 2-3 h on the basis of control group. Both groups were treated for 2 weeks. Clinical efficacies as well as serum copeptin,NT-proBNP,albu-min cobalt binding(ACB)value,European stroke scale(ESS)and functional independence measurement(FIM)score before and after treatment were observed in 2 groups,and the occurrence of ADR was recorded. RESULTS:Total response rate of observation group(90.0％)was significantly higher than that of control group(67.5％),with statistical significance(P<0.05). Before treat-ment,there was no statistical significance in serum peptide,NT-proBNP,ACB value,ESS or FIM score between 2 groups (P>0.05). After treatment,serum copeptin and NT-proBNP levels of 2 groups were decreased significantly,while ACB value,ESS and FIM score were increased significantly;the improvement of observation group was significantly better than that of control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Breviscapine combined with vinpocetine can improve neurological function of acute cerebral infraction patients and show good therapeutic efficacy with good safety.

Objective To study the significance of the expressions of HIF-1? and E-cadherin in cervical carcinoma. Methods The expressions of HIF-1? and E-cadherin (E-cad) were determined in the clinical specimens of 109 cases of cervical carcinoma, 16 cases of cervical intraepithelial neoplasm and 10 cases of normal cervical tissue with immunohistochemical assay. Results There was nearly no expression of HIF-1? in the normal cervical tissue. The positive expression of HIF-1? and E-cad were 81.4% (70/86) and 28.6% (25/86) respectively in the tissue of invasive cervical carcinoma. The rate of positive expression of HIF-1? was significantly higher in invasive cervical carcinoma than in normal cervical tissue and cervical intraepithelial neoplasm (P

Objective To assess the effects of zinc protoporphyrin (ZnPP), an inhibitor of the heme oxygenase (HO), on the colonic interstitial cells of Cajal (ICC) of diabetic rats with colonic slow transit. Methods Diabetes mellitus (DM) model was induced by intraperitoneal injection of streptozotocin (STZ) in Sprague-Dawley rats. Twenty four successfully established DM rats were selected, and 16 healthy rats were served as controls. Six weeks later, gastrointestional (GI) dysfunction was observed by charcoal propulsion experiment in 8 DM rats and 8 controls. The rest rats in DM group were divided into 2 groups: DM rats intraperitoneal injected with PBS (n=8) or with 10 μmol/kg of ZnPP (n = 8) every other day for 3 weeks. The rats in control group (n = 8) were intraperitoneally injected with PBS. The levels of HO and c-kit (the special receptor of ICC) expression were detected by Western blotting. The distribution of ICC was observed by immunohistochemistry and the area of c-kit positive cells was counted. Results The GI propulsion rate in DM rats interfered with PBS was significantly declined compared to that in the controls (63.0%± 1.2% vs 71.8%±2.0%, P<0.05). But it was improved in DM rats interfered with ZnPP (72.5± 2.6%, P<0.05), which showed no significant differentee with that in control group (P>0.05). The expression of HO-1 in close and distant colon of DM rats interfered with ZnPP was decreased (P< 0.05). The expression of HO-2 in close colon and the area of c-kit positive cells of DM rats interfered with PBS was reduced compared with that in controls (P<0.05), but both were improved in DM rats interfered with ZnPP (P<0. 05). Conclusion Administration of ZnPP might be able to protect ICC by its blockage of HO-1 in DM rats with gastrointestinal dysfunction.

AIM: To investigate the effect of cytomegalovirus (CMV) on the expression of ICAM-1 and VCAM-1 in bone marrow stromal cells and on the adhesion of bone marrow stromal cells to hematopoietic cells. METHODS: Flow cytometry was used to detect the expression of adhesion molecules ICAM-1 and VCAM-1 in bone marrow stromal cells, MTT method was used to perform the adhesion assay of bone marrow stromal cells to normal hematopoietic cells. RESULTS: Bone marrow stromal cells could be infected by the CMV used in this experiment; CMV below the dose of 100TCID 50 could not destroy bone marrow stromal cells apparently; The expression of ICAM-1 increased at the early stage(18 h) of CMV infection, the expression of ICAM-1 decreased at the late stage (120 h) of CMV infection. Inactived CMV could also increase the expression of ICAM-1 as alive CMV; The adhesion rate of bone marrow stromal cells to hematopoietic cells increased at the early stage of CMV infection. CMV had no significant effects on the expression of VCAM-1 in bone marrow stromal cells. CONCLUSION: The adhesion capacity of bone marrow stromal cells to hematopoietic cells increased at the early stage of CMV infection, while the adhesion capacity of bone marrow stromal cells to hematopoietic cells decreased at the late stage of CMV infection.

·α-crystallin is the predominant structural protein in the lens.lt is a member of small heat shock proteins ( sHSPs) which has the common functions of HSPs.lt also has anti-apoptotic activity etc.Recently, it has been proved to combine with the cellular membrane of retinal ganglion cells ( RGCs ) to enhance the survival of RGCs and the regeneration of axons, thereby partly restore visual function.But we haven’t come to a unified conclusion of the mechanism.This review is focused on structure and functions of α-crystallin, the protection function and mechanism of α-crystallin towards RGCs after the optic nerve injury.
