The output of ESI-covered scientific papers in BRICs from 2014-01-01 to 2014-06-30 and its impact were analyzed according to the relative publication index ( RPI) and relative citation impact ( RCI) , and the world relative position of scientific research output in BRICs was analyzed by constructing a two-dimensional analysis framework according to the subject specialization index and standard citation impact index, which showed that the absolute output of scientific papers in BRICs was rather high, the distribution of relative scientific research output was not proportional between different subjects, the relative scientific research output in many subjects was signifi-cantly lower than that in the world, the RCI index of 22 subjects in BRICs was lower than that in the world. The specialization degree of subjects was lower in China, Brazil and India than in Russia, the standard RCI index in BRICs was significantly lower than that in the world, indicating that the academic level of scientific papers in BRICs was lower than that in the world. Certain suggestions were put forward for working out the scientific develop-ment policies and adjusting the subject structure in China.

To introduce a strategy for a case of severe pneumonia complicated with lung abscess caused by Fusobacterium necrotum.The pathogen was not identified,but the patient was still coughing up feverish bloody sputum after being treated with meropenem,linezolid and ornidazole.The results of detection of pathogen metagenomes in bronchoalveolar lavage fluid by posterior bronchoscopy suggested that the pathogen was Fusobacterium necrophorum,according to the characteristics of bacteria,the dynamic changes of clinical symptoms,liver and kidney function,body temperature and blood picture infection index,combined with the results of bacterial culture/drug sensitivity test,bronchoalveolar lavage fluid NGS and the pharmacokinetic/pharmacodynamic characteristics of antimicrobial agents,to propose an anti-infective regimen that is strategically adjusted to imipenem cilastatin(1.0 g,ivd,q8h)plus ornidazole(0.5 g,ivd,q12h)for the implementation of pharmaceutical care after adoption by physicians.After 21 days,the patient's severe infection and lung abscess was controlled and patient was discharged.In this case,clinical pharmacists study the bacterial characteristics of Fusobacterium necrotum,review a large number of domestic and foreign literature to track the frontier knowledge of antimicrobial agents,and use their own expertise to provide effective pharmaceutical support for the clinical team,to assist clinical team in the diagnosis and treatment of rare infections,to achieve professional value.

Esophageal cancer has a high morbidity and mortality worldwide， and the burden of esophageal cancer is still heavy in China. The conventional treatments such as radiotherapy and chemotherapy fail to yield a satisfactory outcome， implying that the safe and effective treatments are not available for the majority of patients. At present， esophageal cancer is mainly treated by Chinese medicine combined with radiotherapy and chemotherapy. The retrieval of related papers in Chinese and English reveals that Kang'ai injection， Compound Kushen injection， Kanglaite injection， Xiaoaiping injection， Aidi injection， Bruceae Fructus Oil Emulsion， Cinobufotalin injection， and Shenmai injection have been commonly used in esophageal cancer treatment. These eight injections are either single medicinal or compound preparations， involving 11 Chinese medicinals， which synergize the effects of radiotherapy and chemotherapy and reduce their adverse reactions in the treatment of esophageal cancer. Due to the complexity of Chinese medicinal components， a series of adverse reactions such as phlebitis， phlebosclerosis， and hemolysis may be caused by irrational dosage， administration speed， and compatibility in the use of injection. There are many clinical studies on Chinese medicine injections for anti-esophageal cancer but few studies on their active components and molecular mechanism. This paper reviewed the active components， effectiveness， safety， and mechanism of Chinese medicine injections frequently employed for treating esophageal cancer， in order to provide reference for their clinical application as well as the development of new Chinese drugs.

ObjectiveTo explore the law of women reproductive aging based on theory of "seven-year period" in traditional Chinese medicine（TCM） through analyzing the characteristics of basic sex hormone levels and anti-müllerian hormone levels in women of different ages. MethodsThe data of female who visited Guangdong Provincial Hospital of Traditional Chinese Medicine from January 2018 to December 2022 and accepted basic hormone and anti-müllerian hormone determination were collected retrospectively. According to the age of subjects， they were divided into the "1-2 seven" group （under 21 years old）， "3 seven" group （21-27 years old）， "4 seven" group （28-34 years old）， "5 seven" group （35-41 years old）， "6 seven" group （42-48 years old） and "7 seven" and older group （49 years old and above）. The age， average menstrual cycle in the past 3 months， basic hormone levels including follicle stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， testosterone （T） and FSH/LH value， and anti-müllerian hormone （AMH） levels were collected and compared. ResultsA total of 1221 cases were included. The differences in FSH， LH， FSH/LH values， E₂， T， AMH levels and average menstrual cycle among the groups were statistically significant （P＜0.05 or P＜0.01）. AMH peaked in the "3 seven" group. Compared to those in the "3 seven" group， the FSH/LH value in the "4 seven" group increased， while the LH， AMH and T levels decreased， and the menstrual cycle was shortened （P＜0.01）. The FSH/LH， LH， AMH， T and menstrual cycle in the "5 seven" group were consistent with the changing trend of those in the "4 seven" group， while the FSH and E₂ levels in the "5 seven" group were significantly higher （P＜0.05 or P＜0.01）. Compared to those in the "5 seven" group， the FSH， LH and E₂ levels of the "6 seven" group increased， and the AMH and T levels continued to decrease （P＜0.05 or P＜0.01）. Compared to those in the "6 seven" group， the FSH and LH levels of the "7 seven" and older group continued to increase， and the AMH and E₂ levels decreased （P＜0.01）. ConclusionThe law of women reproductive aging in the "seven-year period" theory is basically consistent with the characteristics of basic sex hormone levels and anti-müllerian hormone levels in women of different ages. The reproductive capacity reaches its peak in the "three-seven-year period" and gradually moves towards reproductive aging in the "four-seven-year period".
