Objective To assess the clinical efficacy of budesonide in combination with salbutamol sulfate and ambroxol through fog inhalation in the treatment of elderly patients older than 70 years with acute exacerbation chronic obstructive pneumonia disease (AECOPD). Methods A total of 58 elderly patients older than 70 years with AECOPD were randomly assigned to receive medication of budesonide in combination with salbutamol sulfate and ambroxol through fog inhalation in addition to conventional therapy ( n = 58 treatment group). In the control group,56 AECOPD patients received conventional therapy (including oxygen uptaking,anti-infection, medication, relieving asthma, eliminating sputum, nutritional support, et al). Results The overall effective rate in the treatment group was 76.79% (43/56) ,which was significantly lower than that in the control group 89. 66% (52/58) ( χ2 = 6. 46, P = 0. 007 ). Blood gas analysis ( pH, PaCO2, PaO2 ) and lung function ( FEV1/FVC, FEV1 occupy prospect% ) outcome were significantly improved after treatment (Ps ＜ 0.05 ). We found no significant difference in the comparison of the blood gas analysis improvement between the treatment and control ( Ps ＞ 0. 05 ), whereas significant difference was observed in the improvement on lung function between the two groups (P ＜ 0. 05 ). Conclusion Combined budesonide with salbutamol sulfate and ambroxol through fog inhalation in addition to conventional therapy has a significant better effect and less side effects on the treatment of AECOPD patients older than 70 years.

BACKGROUND: It has been found that hypoxia inducible 1α (HIF1α) gene can improve the ability of tissues and cells to survive in the ischemic environment, which is of great significance in promoting blood vessel regeneration.OBJECTIVE: To investigate the effect of the recombinant adenovirus Ad-CMV-HIF1αmu-IRES-hrGFP-1 on the proliferation of bone marrow mesenchymal stem cells.METHODS: Passage 3 bone marrow mesenchymal stem cells were cultured and transfected with Ad-CMV-HIF1αmu-IRES-hrGFP-1 virus (experimental group), with non-mutated gene Ad-CMV-HIF1α-IRES-hrGFP (positive control group), with Ad-CMV-IRES-hrGFP-1 empty virus (negative control group), or with no virus solution (blank control group). After transfection for 24 hours, the expression of HIF1α mRNA and protein was detected. Cell proliferation was detected by MTT assay at 24, 48, 72, 96 and 120 hours after transfection.RESULTS AND CONCLUSION: (1) Except that the mRNA expression of HIF1α in the experimental group and the positive control group was significantly higher than that in the negative control group and the blank control group (P < 0.05), there was no significant difference between two groups. (2) The expression of HIF1α protein in the experimental group was significantly higher than that in the positive control group, the negative control group and the blank control group (P < 0.05), and there was no significant difference between the latter three groups. (3) Cell proliferation was faster in the experimental group than the positive control group and the blank control group (P < 0.05), and moreover, there was no significant difference between the latter two groups. Our experimental findings indicate that the recombinant adenovirus-mediated three-point mutant HIF1α combined with hrGFP gene transfected bone marrow mesenchymal stem cells could not only express the target protein, HIF1α, under normoxic conditions, but also promote the proliferation of bone marrow mesenchymal stem cells.

Objective To investigate the clinical, radiological features and therapy of spinal actinomycotic infection complicated with spinal cord compression.Methods The data of three patients confirmed by histopathology were analyzed retrospectively.Results All three patients presented with infection of cervical thoracal vertebral bodies and soft tissue, and with syndrome of spinal cord compression. MRI examination revealed destruction of vertebral bodies, extradural soft tissue mass and spinal cord compression. Histopathological examination confirmed the infection of actinomycete in all three patients. Granulomatous inflammation could be seen in two cases, while extradural abscess was found in the other one case. Three patients all received the operation of abscess draining and vertebral canal decompression. Large-dose of Penicillin G following operation was administrated intravenously for 4～8 weeks, and then changed to oral application for another 4～6 months. Follow-up showed significant clinical effect in these three patients.Conclusions Radiologic and clinical findings of spinal actinomycotic infection complicated with spinal cord compression are nonspecific, and the diagnosis of this disease depends on pathological and microbiologic exams. Treatments with abscess draining, vertebral canal decompression and large-dose of antibiotic may achieve good clinical outcome.
