Objective To study the efficacy of bronchoalveolar lavage(BAL)combined with prone positioning in children with Mycoplasma pneumoniae pneumonia(MPP)and atelectasis and its effect on pulmonary function.Methods A prospective study was conducted on 94 children with MPP and atelectasis who were hospitalized in Ordos Central Hospital of Inner Mongolia from November 2020 to May 2023.The children were randomly divided into a treatment group and a control group,with 47 children in each group.The children in the treatment group were given conventional treatment,BAL,and prone positioning,and those in the control group were given conventional treatment and BAL.The two groups were compared in terms of fever,pulmonary signs,length of hospital stay,lung recruitment,and improvement in pulmonary function.Results Compared with the control group,the treatment group had significantly shorter time to improvement in pulmonary signs and length of hospital stay and a significantly higher rate of lung recruitment on day 7 of hospitalization,on the day of discharge,and at 1 week after discharge(P<0.05).Compared with the control group,the treatment group had significantly higher levels of forced vital capacity(FVC)as a percentage of the predicted value,forced expiratory volume(FEV)in 1 second as a percentage of the predicted value,ratio of FEV in 1 second to FVC,forced expiratory flow at 50%of FVC as a percentage of the predicted value,forced expiratory flow at 75%of FVC as a percentage of the predicted value,and maximal mid-expiratory flow as a percentage of the predicted value on the day of discharge and at 1 week after discharge(P<0.05).There was no significant difference in the time for body temperature to return to normal between the two groups(P>0.05).Conclusions In the treatment of children with MPP and atelectasis,BAL combined with prone positioning can help to shorten the time to improvement in pulmonary signs and the length of hospital stay and promote lung recruitment and improvement in pulmonary function.

Drug instructions,the statutory and technical documents recording effectiveness and safety information,are an important basis for guiding doctors,pharmacists,and patients to use drugs rationally,and their scientificity,standardization,and accuracy directly affect the medication safety of the public. The sections of adverse drug events,contraindications,precautions,warnings,and application for specific populations in drug instructions directly express safety information and measures for rational use of drugs. In the drug life cycle,marketing authorization holders( MAHs) need to update safety information in the instructions promptly to ensure the safety and effectiveness of clinical drug medication. At present,revising instructions is an important measure to control drug risks. In the drug life cycle,in order to standardize the revision of safety information in the instructions by MAHs and eliminate inexact terms such as " unclear",the Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,have been established under the guidance of Standardization Department,China Association of Chinese Medicine. Therefore,on the basis of the existing rules and regulations,the standardized technical procedures for revising instructions came into being to help clinical safe and rational medication of drugs,and implement the strategy of " Healthy China".

Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,were proposed by Professor ZHANG Bing from Research Center for Pharmacovigilance and Rational Use of Traditional Chinese Medicine,and underwent centralized management by Chinese Association of Chinese Medicine. They were officially released on July 23 and implemented on July 31,2021. The series of group standards consist of six sections,including general principles,adverse drug events,contraindications,precautions,application for special populations,and warnings. The section of general principles is comprised of holistic and programmatic expressions,which explain the general technical requirements for revising the marketed Chinese patent medicine instructions. The other five sections focus on information collection,screening,transformation,and illustration of specific items,forming a standardized revision technical process. This series of standards is the result of multiple rounds of research and the suggestions of more than 200 experts in different professional fields of " medicine-pharmacy-management-law-enterprise" have been gathered therein to reach a consensus. With the purposes of establishing standardized technical specifications for the revision of safety information in the marketed Chinese patent medicine instructions,guiding marketing authorization holders in revising the instructions,filling the gaps in the research of Chinese patent medicine instructions,promoting the deve-lopment of pharmaceutical care and academic research,and encouraging the rational and safe medication of Chinese patent medicine,the series of group standards is of great significance.

Objective: To investigate the prevalence of allergic rhinitis (AR) in 3 central cities (Chifeng, Hohhot, Ordos) and the surrounding rural areas of Inner Mongolia region, and to look for possible risk factors related to the disease. Methods: From March to October of 2019, a multi-stage stratified random sampling epidemiological survey was conducted in Chifeng, Hohhot, Ordos and rural areas. The AR-related factors of the population were obtained in the form of face-to-face questionnaire survey, and the skin prick test (SPT) was taken for the participants. AR disease was diagnosed according to the "Guidelines for the Diagnosis and Treatment of Allergic Rhinitis (2015, Tianjin)". The daily airborne pollen situation in the three regions was monitored during the same period. SPSS 23.0 was used to analyze all survey results. Results: A total of 6 818 questionnaires were recovered, with 6 393 valid questionnaires. The self-reported prevalence of AR was 27.72% (1 772/6 393) and the confirmed prevalence of AR was 17.10% (1 093/6 393). The prevalence of perennial AR was 1.83% (117/6 393) while the prevalence of seasonal AR was 15.27% (976/6 393). The prevalence of AR diagnosed in females was higher than that in males (19.19% vs 15.34%, χ²=16.594, P<0.001) and the prevalence of females in the two age groups of 36-45 years and 46-55 years was significantly higher than that of males (18.17% vs 9.73%, 14.13% vs 7.25%, χ² value was 23.848, 18.772, respectively, all P<0.001). The prevalence of confirmed diagnoses in ethnic minorities was higher than that of Han nationality, and the prevalence of confirmed diagnoses in urban areas was higher than that in rural areas (23.13% vs 16.20%, 27.27% vs 9.71%, χ² value was 24.516, 336.024, respectively, all P<0.001). The main nasal symptoms of AR patients were sneezing (91.31%), nasal congestion (85.91%) and nasal itching (85.00%). The most common concomitant disease of AR was allergic conjunctivitis (73.99%). Asthma (OR=6.629), food allergy (OR=3.236), drug allergy (OR=1.786), application of antibiotics (OR=1.553), recent home decoration (OR=2.307), and smoking (OR=1.322) were the AR related risk factors. The highest proportion of SPT positive reactions was Artemisia annua (80.15%). The peak period of clinical symptoms of AR patients in Inner Mongolia region was July to September, which was consistent with the second peak period of airborne pollen monitoring. Conclusions: The prevalence of AR in central cities and the surrounding rural areas of Inner Mongolia region is 17.10%, and Artemisia species is the most important pollen allergen in this area. History of asthma, food allergy, drug allergy, antibiotic use, home decoration and smoking history are the related risk factors for AR.

Diabetic retinopathy (DR) is one of the most common microangiopathies of diabetes mellitus (DM). It is due to abnormal blood glucose metabolism caused by insufficient insulin secretion or decreased activity. Its pathogenesis is complex, related to multi-gene inheritance and environmental factors. At present, the etiologic study of DR has been gradually deepened at home and abroad, but the epidemiological study of minority DR is lacking. This paper reviews DR's characteristics, ethnic differences and its characteristics in ethnic minority.

Objective::To establish a pre-column derivatization reverse-phase high-performance liquid chromatography (RP-HPLC) method for the simultaneous determination of 17 amino acids in Cynomorii Herba from different producing areas and conduct a multivariate statistical analysis. Method::RP-HPLC with pre-column derivatization was employed, with phenyl isothiocyanate (PITC) as derivatization reagent. Separation was performed on a WondaSil C₁₈-WR column (4.6 mm×150 mm, 5 μm), with 0.05 mol·L^-1 sodium acetate solution (pH 6.5) as mobile phase A, and acetonitrile-methanol-water (3∶1∶1) as mobile phase B for gradient elution at a flow rate of 0.8 mL·min^-1. The detective wave length was set at 254 nm, and the column temperature was maintained at 35 ℃. Principal component analysis (PCA) and systematic cluster analysis (HCA) models were established for multivariate statistical analysis and quality evaluation. Result::17 Kinds of amino acid were detected in Cynomorii Herba, 7 of which were essential amino acids. The 17 amino acids showed good linearity in respective concentration range, r = 0.999 0-0.999 9.The average recoveries were between 98.03%-103.89%with RSD<3.5%. The results of PCA and HCA were basically the same, and both methods can be used to clearly distinguish Cynomorii Herba from 12 municipal producing areas into 6 regions. PCA can be used to classify Cynomorii Herba according to different municipal or provincial production areas, and HCA can be used to classify it according to provincial production areas. It showed that the amino acid contents in Cynomorii Herba from different municipal and provincial producing areas had differences, and the content distribution showed obvious geographical clustering characteristics. PCA showed that Cynomorii Herba from Gansu province and Inner Mongolia had higher amino acid contents and better quality as compared with other producing areas. Conclusion::The established method can be used for content determination of 17 amino acids in Cynomorii Herba from different producing areas, and provide a reference for its comprehensive quality evaluation.
