Clinical Efficacy Analysis of Tiotropium Bromide Combined with Budesonide and Formoterol Inhalation in Treating COPD

Objective:To analyze the clinical efficacy of tiotropium bromide(TB)combined with budesonide formoterol(BUD/FM)inhalation in treating chronic obstructive pulmonary disease(COPD).Methods:62 COPD patients admitted to the hospital between June 2020 and December 2022 were selected as samples for this study.The patients were divided into a combination group and a conventional group using the random number table method,with 31 cases in each group.The patients in the combination group were treated with TB combined with BUD/FM inhalation,whereas the patients in the conventional group were treated with BUD/FM inhalation only.The treatment efficacy and changes in lung function indicators of both groups were compared.Results:The total efficacy of treatment in the combined group was higher than that in the conventional group,and the difference was statistically significant(P<0.05).Before treatment,there was no difference in pulmonary function indicators between the two groups(P>0.05).After three months of treatment,all lung function indicators of the combined group were higher than those of the conventional group,and the difference was statistically significant(P<0.05).Conclusion:Combining TB with BUD/FM inhalation therapy increases the efficacy of treatment for patients with COPD.Besides,it also improves lung function and leads to a better prognosis.

Effect of hydrogen intervention on refractory wounds after radiotherapy:A case report

BACKGROUND Patients with keloids who receive radiotherapy(RT)after surgery can develop refractory wounds that cannot be healed by the patient's own repair system.Such chronic wounds are uneven and complex due to persistent abscess and ulceration.Without external intervention,they can easily result in local tissue necrosis or,in severe cases,large area tissue resection,amputation,and even death.CASE SUMMARY This article describes the use of hydrogen to treat a 42-year-old female patient with a chronic wound on her left shoulder.The patient had a skin graft that involved implanting a dilator under the skin of her left shoulder,and then transferring excess skin from her shoulder onto scar tissue on her chest.The skin grafting was followed by two rounds of RT,after which the shoulder wound had difficulty healing.For six months,the patient was treated with 2 h of hydrogen inhalation(HI)therapy per day,in addition to application of sterile gauze on the wound and periodic debridement.We also performed one deep,large,sharp debridement to enlarge the wound area.The wound healed completely within 6 mo of beginning the HI treatment.CONCLUSION After HI therapy,the patient showed superior progress in reepithelialization and wound repair,with eventual wound closure in 6 mo,in comparison with the previous failures of hyperbaric oxygen and recombinant bovine basic fibroblast growth factor therapies.Our work showed that HI therapy could be a new strategy for wound healing that is cleaner,more convenient,and less expensive than other therapies,as well as easily accessible for further application in clinical wound care.
