The eighteen antagonisms summarized by predecessors may not be absolute contraindications．The author obtained the inspiration of the antagonism medicinals “aconite-pinellia” from the external treatment of Xingxia painkiller ointment created by Chen Guocheng．The present paper provides a concise overview of the origin and application of anti-drug compatibility,with a specific focus on Chen Guocheng's expertise and insights regarding the external use of aconite combined with pinellia．It is postulated that diverse approaches can be employed to modulate the compatibility between aconite and pinellia,thereby offering novel perspectives for ensuring the safe utilization of this drug combination in clinical practice．

肉芽肿性小叶性乳腺炎（GLM）是一种临床较为难治的、慢性、炎症性的疾病,虽不会影响患者的生命,但是对患者的生理、心理造成了一定程度的影响,近年来该病的发病率有逐年上升的趋势。“治未病”是中医的基本思想之一,在疾病的预防、诊治方面具有重要意义。该文尝试将中医“治未病”思想应用于GLM的预防和治疗中,试图构建独特的中医预防GLM质量管理模式,以期为GLM防治提供新的思路。

Granulomatous lobular mastitis（GLM）is a chronic,inflammatory disease that is difficult to treat．Although it does not affect the patient's life,it has a certain degree of physiological and psychological impact on the patient,and in recent years the incidence of this disease has been increasing year by year．“Treating Disease Before Its Onset” is one of the basic ideas of Chinese medicine,which is of great significance in the prevention,diagnosis and treatment of diseases．In this paper,we try to apply the idea of “Treating Disease Before Its Onset” in Chinese medicine to the prevention and treatment of GLM,and attempt to construct a unique quality management model of Chinese medicine for the prevention of GLM,with a view to providing new ideas for the prevention and treatment of GLM．

Objective To investigate the clinical effect of the rehabilitation guidance protocol of spinal surgery in perioperative period．Methods A total of 184 patients undergoing selective surgery in the spine surgery department of the Third People's Hospital of Bijie City were selected．The conventional rehabilitation group was the control group,which preoperative and postoperative management was continued with the original rehabilitation program of spine surgery;the rehabilitation guidance group was the observation group：the new rehabilitation behavior code program was used to provide systematic preoperative pre-rehabilitation guidance and postoperative standardized management．The patients' activities of getting up after surgery,days in hospital,economic use,pain recovery and satisfaction survey were compared．Results Before surgical treatment,the gender,age and disease distribution of patients were compared（P>0.05）．After surgical treatment,observation group：Postoperative time of getting out of bed（3.09±1.02）d,length of hospitalization（10.73±3.96）d,hospitalization expenses（17 388±5 217）yuan,VAS score of 2 days after surgery（3.04±1.19）,VAS score of discharge（2.36±1.25）,inpatient satisfaction（89.80±8.12）,were significantly better than the control group：Postoperative activity time（4.44±1.58）d,length of hospitalization（13.38±2.73）d,hospitalization expenses（23 242±7 971）yuan,VAS score（4.01±1.44）,VAS score at discharge（3.39±1.38）,hospitalization satisfaction（80.27±11.45）．Compared with the control group,the new rehabilitation guidelines significantly reduced postoperative pain,bed time and hospital days in spinal surgery patients（P<0.05）．Conclusions Speeding up the postoperative rehabilitation of patients and improving the rate of postoperative recovery,improving patients' sense of access to medical treatment,can make the doctor-patient relationship more harmonious．

目的 利用靶向二代测序技术探究天津市发热呼吸道症候群病原特征,分析病原流行特征,总结规律,为发热伴呼吸道症候群患者治疗策略提供指导。方法 收集2023年1月—2023年12月天津地区某四家医院初诊为发热伴呼吸道症候群的4 039例病例,通过tNGS技术检测,分析鉴定病原微生物,研究不同标本类型病原微生物分布、年龄分布、性别分布、不同时间季节感染分布、微生物类型分布趋势等。结果 4 039例经tNGS技术检测,共检测出90种潜在病原体,总阳性率为94.80%（3 829/4 039）。包括36种细菌、29种病毒、5种非典型病原体和20种真菌。不同种类病原体检出频次排序：革兰阴性细菌（G-细菌）>RNA病毒>DNA病毒>革兰阳性细菌（G+细菌）>真菌>非典型病原体。男女性别阳性检出率比较差异无统计学意义（χ²=0.249,P=0.618）;不同年龄段人群病原体谱有异质性,且阳性患者多分布在0~10岁和>60岁,阳性也集中在该两类人群,阳性率分别为47.90%（1 834/3 829）和31.24%（1 196/3 829）。在单一感染中,肺炎支原体占比最高,为4.91%,其次为新型冠状病毒,占1.59%,再次为呼吸道合胞病毒,占1.23%。不同季节不同感染类型具有差异,整体呈现夏冬季混合感染率高的特点,即夏季新冠病毒合并细菌（鲍曼不动杆菌、肺炎链球菌）,冬季肺炎支原体合并甲型、乙型流感病毒多见。肺炎支原体对大环内酯类药物耐药率随月份呈现增加趋势。结论 tNGS 技术在天津市发热呼吸道症候群样本中获得了较高的病原体检出率,病原体覆盖面广,通过提供更多的病原体信息,可以有效辅助鉴别混合感染和耐药信息。

Objective Using targeted next-generation sequencing technology to explore the composition of the pathogenic spectrum of febrile respiratory syndrome ,analyze the epidemic characteristics of the pathogen,summarize the rules,and provide accurate guidance for the treatment strategy of patients with febrile respiratory syndrome．Methods By tNGS detection of 4039 cases with fever with respiratory diseases in four hospitals in Tianjin in 2023,pathogenic microorganisms were analyzed and identified,and the distribution of pathogenic microorganisms,age distribution,gender distribution,infection distribution in different times and seasons,and distribution trend of microbial types in different specimen types were studied．Results In 4039 cases,90 potential pathogens were detected,the total positive rate was 94.80%（3 829/4 039）,including 36 kinds of bacteria,29 kinds of viruses,5 kinds of atypical pathogen and 6 kinds of fungi．The order of detection frequency of different types of pathogens：G-bacteria > RNA virus > DNA virus > G+ bacteria > fungi > atypical pathogens．There was no significant difference in the positive rate of male and female between the two groups（χ²=0.249,P=0.618）．The pathogen spectrum of different age groups was heterogeneous． The positive patients were mostly distributed in 0-10 years old [47.90%（1 834/3 829）] and >60 years old [31.23%（1 196/3 829）]．Among the single infection,Mycoplasma pneumoniae accounted for the highest proportion,4.91%（188/3829）,followed by 2019-nCoV,1.59%（61/3 829）,and respiratory syncytial virus,1.23%（47/3 829）．There were differences in different infection types in different seasons,and the overall characteristics of mixed infection rate in summer and winter were high． In summer,the new coronavirus was combined with bacteria（Acinetobacter baumannii,Streptococcus pneumoniae）,and in winter,Mycoplasma pneumoniae was combined with influenza A and B viruses．The resistance rate of Mycoplasma pneumoniae to macrolides showed an increasing trend with the time．Conclusions The tNGS technology had obtained a high pathogen detection rate in the samples of febrile respiratory syndrome in Tianjin．By providing more pathogen information,it can be effectively applied to the etiological diagnosis of respiratory infectious diseases and assist in the identification of mixed infections and drug resistance information．
