Objective To evaluate the effect and safety of tiotropium plus sustained-release theophylline in treating stable moderate chronic obstructive pulmonary diseases (COPD) . Methods A randomized clinical trail was conducted in 80 patients with stable moderate COPD, who were admitted to our hospital from March 2008 to December 2009. All patients were divided into two groups randomly and accepted tiotropium (groupⅠ ,n =40) or tiotropium plus sustained-release theophylline (group Ⅱ ,n =40) treatment for 12 weeks. Results Seventy patients completed the study,in which 36 cases had tiotropium alone and 34 cases had combination therapy. At the end of treatment, no statistically significant difference was found between the two groups in the comparisons of FEV1, FEV1%, FVC, FEV1/FVC, activity score and impacts score of the St George's Respiratory Questionnaire (SGRQ) (Ps > 0. 05). While the symptoms score (53.08 ± 12.25 vs.59.39±9.74,t=2.39,P<0.05) and total score (23. 91 ±2. 57 vs. 25. 27 ±2.14, t =2.40, P <0.05) of SGRQ were significantly lower in group Ⅱ compared to group Ⅰ. Six adverse events,including dry mouth (n =4), palpitation (re = 1) , constipation (n = 1), were observed in tiotropium alone group during the treatment period. Eleven adverse events were observed in combination treatment group, including dry mouth (re = 3) ,stomach discomfort or nausea (n = 3), diarrhea (re = 2) , palpitation (n = 2), constipation (n = 1) . The incidences of adverse reactions of two groups had no significant difference (P > 0. 05). Conclusion Compared with the single application of tiotropium, tiotropium plus sustained-release theophylline therapy can alleviate symptoms and improve life quality in patients with stable moderate COPD,without significantly increasing adverse reactions.

Objective To study the polysomnography(PSG) indexes which can reflex the severity of anoxia in obstructive sleep apnea-hypopnea syndrome(OSAHS) more comprehensively. Methods Sixtythree OSAHS patients' PSG indexes, including the apnea-hypopnea index (AHI), apnea time/total sleeping time (AM), hypoventilation time/total sleeping time (HM), mean oxygen saturation (MSaO2),the lowest oxygen saturation (LSaO2) and the longest apnea time (LAT) were analyzed retrospectively. Results In patients with OSAHS,the AHI was positively correlated with AM, HM and LAT(P < 0.01 or < 0.05 ), and was negatively correlated with MSaO2 and LSaO2(P < 0.01 ). The AHI had linear regression relationship with AM,HM and LSaO2 (F =202.264,P <0.01). Conclusions Among the PSG indexes,AM is intimately associated with AHI. Therefore,compared with LSaO2,AM and HM can reflex the severity of anoxia in patients with OSAHS more accurately.

Aim To obtain the encoding gene sequences of TEM-type ?-lactamases produced by 4-strain Klebsiella pneumoniae in Zhejian g Province, identify their genotypes and study some properties of these TEM-typ e ?-lactamases.Methods The encoding genes of TEM-type ?-la ctamases produced by 4 isolates were amplified by PCR. The purified PCR products were ligated with pGEM-T easy vectors, expressed in E. coli DH 5?, and sequenced by Sanger's dideoxy chain termin ation composition method. Compared with anino acid sequences in the GenBank,TEM -types of the ?-lactamases was determined. The genes of TEM ?-lactamases were ligated with pET-28 c vector to express recombinant proteins in E. coli DH 5?. Plasmids were extracted from the p ronucleus expression strains and PCR was performed to determine whether the pron ucleus expression was successful or not. Their phenotypes were determined by ESB Ls phenotype affirmative test. The isoelectric points (pIs) of the recombinant p roteins were determined by isoelectric focus. Conjugation test was performed to determine whether their genes existed in plasmid or chromosome. Results The encoding genes of ?-lactamases were determined as TEM by PCR. It s PCR product had 1 009 nucleotides. The pI of the novel TEM ?-lactamase was 5.4. The enzyme was determined as non-ESBLs by ESBLs phenotype affirmative tes t.Transconjugants were successfully selected from the paternal producers in conj ugation tests. The TEM-type ?-lactamase produced by 4 strains was determined as TEM-105(AF516720) by GenBank. Conclusion The ?-lactamase produced by 4-strain K. pneumoniae from 4 patients in Zhejiang Province was TEM-105. It was the first report of TEM-105 type ?-lactamase produced by 4-st ain K. pneumoniae from China in the world.
