Objective To evaluate the therapeutic effect of Maxing-Shigan decoction combined with salmeterol/fluticasone inhalation for acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods A total of 86 patients with acute exacerbation of COPD were enrolled and randomly divided into a salmeterol/fluticasone group (41 patients) and a combined treatment group (45 patients). The salmeterol/fluticasone group was treated by salmeterol/fluticasone inhalation, and the combined treatment group by Maxing-Shigan decoction combined with salmeterol/fluticasone inhalation. Serum C-reactive protein (CRP) was detected by a immunonephelometric assay, and Toll-like receptor 9 (TLR9) in hemocytes was detected by flow cytometry. The score of the syndromes in traditional Chinese medicine (TCM), such as cough, sputum, gasping and shortness of breath, as well as pulmonary function and therapeutic effect were evaluateds. Results After the treatment, the serum C-reactive protein in the combined treatment group was significantly lower than that in the salmeterol/fluticasone group (4.3 ± 1.2 mg/L vs. 8.4 ± 2.5 mg/L;t=5.417, P<0.01), and the TLR9 expression was significantly higher (1.9 ± 0.7 vs. 1.6 ± 0.4;t=3.418, P<0.05). The scores of the syndromes in TCM, such as cough (1.7 ± 0.6 vs. 3.8 ± 1.1;t=2.859, P<0.05), sputum (1.6 ± 0.4 vs. 3.9 ± 1.2;t=3.027, P<0.05), gasping (1.2 ± 0.5 vs. 3.4 ± 1.3;t=3.416, P<0.05) and shortness of breath (1.5 ± 0.7 vs. 3.7 ± 1.6;t=3.468, P<0.05) in the combined treatment group were significantly lower than those in the salmeterol/fluticasone group. The forced expiratory volume in first second (75.4 ± 5.8 L vs. 62.8 ± 6.9 L;t=3.526, P<0.05) and the percentage of forced expiratory volume in first second to forced vital capacity (85.7%± 10.3%vs. 71.9%± 15.4%;t=5.648, P<0.01) in the combined treatment group were significantly higher than those in the salmeterol/fluticasone group. The time to symptoms alleviated (3.4 ± 0.7 d vs. 5.6 ± 1.2 d; t=3.256, P<0.05) and the use dose was (1.8 ± 0.2) ×103μg vs. (5.3 ± 0.4)×103μg, and use times of salmeterol/fluticasone (7.4 ± 1.3 vs. 16.5 ± 3.4;t=4.574, P<0.05) in the combined treatment group were significantly decreased than those in the salmeterol/fluticasone group. The total effective rate in in the combined treatment group were significantly decreased than those in the salmeterol/fluticasone group (84.4% vs. 73.2%; χ2=4.519, P<0.05). Conclusion Maxing-Shigan decoction combined with salmeterol/fluticasone inhalation can improve the pulmonary function in patients with acute exacerbation of COPD, its effiency is suppior to salmeterol/fluticasone inhalation alone.

Objective To explore influence of different positive end expiratory pressure(PEEP)level on ventilative efficincy of premature infant with respiratory distress syndrome(RDS).Methods Forty preterm infants who were diagnosed RDS and needed ventilation were randomly assigned to lower PEEP(0.49~0.59 kPa)and high PEEP(0.59~0.78 kPa)group.They were treated by ventilation and pulmonary surfactant(PS).When they were medically stable,blood gas was done at 15 min,2,6,12,24 h after ventilation.Then the ratio of pa(O2)/FiO2,oxygen index(OI),ventilation index were calculated.Result The ratio of pa(O2)/FiO2,OI,ventilation index were better in lower PEEP group than those in high PEEP group(Pa

Objective To explore the effects of dopamine and dobutamine on thyroid stimulating hormone(TSH),total thyroxine(T4) and growth hormone(GH) in preterm infants with hypotension.Methods Forty-seven preterm infants with hypotension were enrolled in the stu-dy,and 38 preterm infants remained hypotensive after two dose of isotonic saline solution,who were divided into two groups and assigned to receive dopamine or dobutamine.Drug infusion were all started at 4 ?g /(kg?min) and the dose increased by 2 ?g /(kg?min) in a stepwise fashion until either the mean blood pressure normalized or a maximal dose 20 ?g /(kg?min) was reached.Haemodynamic variables and se-rum levels of TSH,T4,and GH were assessed during the first 72 h of treatment and the first 3 d after stopping treatment.Microplate luminometer was used to test TSH,T4,GH levels.Results Necessary cumulative and mean drug doses and maximum infusion required to normalize blood pressure were significantly higher in the dobutamine group than those in the dopamine group(Pa0.05].Conclusions Dopamine and dobutamine both increase the syste-mic blood pressure,with higher drug doses in dobutamine group.Dopamine reduces levels of serum TSH,T4 and GH in preterm infants but such suppression is quickly reversed after treatment is stopped.

Aconite roots are a common clinical poisonous herb in Chinese herb. It has the effect of restoring yang and rescuing collapse, supplementing fire and assisting yang, eliminating cold and relieving pain. It is used in the treatment of yang collapse and yang deficiency syndromes. It is called principle medicine of all medicines. Monks-hood polysaccharide is one of effective components in Aconite roots. The study found that monkshood polysaccharide has effects of immune regulation, antitumor, myocardial preservation, lipid lowering, etc.

To explore whether the imprinting status of IGF-2 in the malignant epithelial ovarian tumors is different from that in benign tumors, the target sequences (DNA and RNA) which contain a polymorphism site for ApaI restriction endonuclease digestion were amplified with PCR and RT-PCR methods. Then the PCR/RT-PCR products were digested by ApaI. The IGF-2 transcriptional pattern came out from the results of endonucleases digestion. Among the 36 cases of benign epithelial ovarian tumors, 20 were heterozygous for ApaI locus and all showed genomic imprinting. While in the malignant group, 22 were heterozygous for ApaI locus but six were found to lose imprinting. Significant differences existed between the two groups (P < 0.05). Loss of imprinting of IGF-2 may serve as a marker for differentiating the malignant ovarian cancers from the benign ones. In a new field of molecular genetics, our research provides an experimental basis for genetic diagnosis and treatment of the ovarian cancers.

Objective To observe the changes in cytokeratin expression pattern of the regenerated epithelia of dermal tissue flaps transferred for intraoral mucosal reconstruction. Methods Mucosal defects were made on the right buccal mucosa of 12 healthy adult dogs, and then were reconstructed immediately by pedicled platysma myodermal flaps (PMDF). Changes in the expression patterns of CK10 and CK19 of the epithelia on the flaps were observed by immunohistochemical staining. Results Low level of CK19 expression was found in the basal layer and the layers superior to the basal layer of the regenerated epithelia at 4 week after transferring the dermal tissue flaps. The expression pattern of keratin in PMDF was identical to that of the normal skin 12 weeks later. Conclusion The regenerated epithelia remain the original structure without mucosal changes.
