AIM:To investigate the relationship of clinical efficacy,blood trough concentration and adverse reavtion,which in the treatment of methicillin-resistant Staphylococcus aureus infection with Vancomycin.METHODS:The clinical data of 82 hospital patients who were infected by methicillin-resistant Staphylococcus aureus and treated with Vancomycin from January 2008 to October 2009 were retrospectively analyzed the clinic efficacy,bacteriological treatment,adverse reaction were observed,and the blook trough concentration was detected.RESULTS:The treatment effective rate of Vancomycin-blood trough concentration which was less than 5 ?g/mL,in the range of 5-10 ?g/mL,and greater than 10 ?g/mL were 68.75%,72.73% and 81.82%.The bacterial clearance rates were 62.50%,68.18% and 72.73%.One case of blood trough concentration of 14.6 ?g/mL in patients with renal toxicity.CONCLUSION:Increasing the blood trough concentration of Vancomycin can improve the treatment of methicillin-resistant Staphylococcus aureus infection in the efficacy and bacterial eradication rates,but the probability of renal toxicity adverse reactions will also increase accordingly.

Huopo Xialingtang is a famous classical formula for treating dampness and warmth， which is included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. In this paper， bibliometric methods was used to collect the literature related to Huopo Xialingtang， and 16 items of related literature were retrieved， involving five medical books， which were used to textual research on the origin， name， composition， drug dosage， preparation method， processing and main treatment symptoms of this formula. The results indicated that Huopo Xialingtang was originated from Yiyuan written by Shi Funan in the Qing dynasty， and and was later named and extended by He Lianchen. The composition of the proposed formula was consistent with the record of Yiyuan， and the origin of each Chinese materia medica was basically clear. Houpo was the dried bark and root bark of Magnolia officinalis， Zexie was the dried tubers of Alisma orientale， Kuxingren was the dried mature seeds of Prunus armeniaca， Doukou was the dried mature fruits of Amomum kravanh， the origin of Tuhuoxiang was consistent with the 2018 edition of Shanghai Standards of Processing Chinese Crud Drugs， and the origins of the remaining Chinese medicines were consistent with the 2020 edition of Chinese Pharmacopoeia. The converted dose of each Chinese medicine was 7.46 g for Agastache rugosa， 3.73 g for Magnoliae Officinalis Cortex， 8.39 g for Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine， 11.19 g for Poria， 11.19 g for Armeniacae Semen Amarum， 14.92 g for Coicis Semen， 2.61 g for Amomi Fructus Rotundus， 5.60 g for Polyporus， 5.60 g for Alismatis Rhizoma， 14.92 g for Tetrapanacis Medulla. Huopo Xialingtang was initially used for the treatment of dampness and warmth at the beginning of the disease， and was later expanded to treat dampness obstruction， dampness-warming dysentery and so on， but always with the dampness-heat in the lungs and spleen as the pathogenesis. In modern times， the clinical application is more extensive， used in digestive， respiratory， endocrine， nervous system and other types of diseases， especially for chronic gastritis， stomach pain and fever. By combing the ancient literature of Huopo Xialingtang， we verified the origin of the formula and determined the key information of the prescription， which can provide literature reference for the clinical application and drug development of this formula.
