This paper summarized the nursing of a patient with type 2 diabetes mellitus complicated with invasive pulmonary aspergillosis resulting in the formation of a cavity in the upper lobe of the right lung causing hemoptysis. Nurses had closely observe the changes in the patient's condition and carried out comprehensive interventions including hemoptysis care, dietary care, disinfection and isolation, cough and sputum production and oxygen therapy care, Traditional Chinese Medicine nursing, psychological care and health education. Efforts were made to reduce the risk of hemoptysis, control the blood glucose, improve immunity and quality of life of the patient.

In December 1946, college student Shen Chong was raped by an inebriated US Marine in Peking. Although the initial trial by the court martial in China found the Marine guilty, the verdict was overturned by Judge Advocate General of the Navy in Washington. Student protests quickly turned into a nationwide anti‐American movement. In contrast to previous studies that emphasise the event's political impacts from the perspective of American imperialism and Chinese nationalism, this article shifts both the focus and scale of inquiry from the macro of national and international politics to the micro of a Chinese woman's body, investigating the particular mechanisms through which injustice towards a Chinese woman was executed in the US justice system. Probing along and against the 'archival grain' in both countries and languages, this article argues that such injustice was not only grounded in the political hegemony of the US military empire, but also resulted from a flawed legal system steeped in racial and sexual biases against Chinese women. This article further suggests that in order to understand this key chapter of Sino–US history, we must bring back to the centre of our study the injured woman, a figure that has remained largely invisible in the grand narratives of conventional political and diplomatic history.

Bacillus subtilis HNDF2-3 can produce a variety of lipopeptide antibiotics with lower production. To improve its lipopeptide production, three genetically engineered strains were constructed. The results of real-time PCR showed that the highest transcriptional levels of the sfp gene in F2-3sfp, F2-3comA and F2-3sfp-comA were 29.01, 6.65 and 17.50 times of the original strain, respectively, while the highest transcriptional levels of the comA gene in F2-3comA and F2-3sfp-comA were 10.44 and 4.13 times of the original strain, respectively. The results of ELISA showed that the malonyl-CoA transacylase activity of F2-3comA was the highest, reaching 18.53 IU/L at 24 h, the data was 32.74% higher than that of the original strain. The highest total lipopeptide production of F2-3sfp, F2-3comA and F2-3sfp-comA induced by IPTG at optimal concentration were 33.51, 46.05 and 38.96% higher than that of the original strain, respectively. The results of HPLC showed that iturin A production of F2-3sfp-comA was the highest, which was 63.16% higher than that of the original strain. This study laid the foundation for further construction of genetically engineered strains with high lipopeptide production. [ABSTRACT FROM AUTHOR]

While well-fed and well-dressed GIs in China had plenty of beef, eggs, milk, alcohol, cigarettes, and candies, Chinese soldiers ate rice, bamboo roots, and pickles, and looked small, malnourished, and filthy.[76] Such food disputes cast a shadow over Sino-U.S. relations throughout the war, and continued into the postwar era, when the United Nations Relief and Rehabilitation Administration clashed with the Chinese National Relief and Rehabilitation Administration over distribution of war surplus supplies and relief goods in China.[77] Food politics extended far beyond the store, kitchen, and dining room, reaching the cattle farmland, the slaughterhouse, presidential memos, and national treaties. In January 1947, William W. Lockwood, future president of the Association for Asian Studies, who had served for eighteen months as a U.S. Army officer in China, wrote that the "first venture in large scale American tourism in China" caused "many sour, even hostile, reactions to the Chinese." According to John Hersey, an eminent reporter and writer born into a missionary family in China, the winning jockey was crowned "Miss Rickshaw" by General Albert C. Wedemeyer, commander of American forces in China, and "the winning horse was given a floral horseshoe" and a prize of about seven U.S. dollars.[23] While Chinese media criticized the implicit dog analogy, the winning rickshaw man was invited by the chairman of Madison Square Garden to compete with a famous American runner in New York City.[24] After reports in major U.S. periodicals, this GI creation led to such an enthusiastic response that a Sino-American sporting event was proposed to recreate the spectacle and provide a thrilling experience for audiences back home.

Barley leaf stripe, caused by Pyrenophora graminea, is an essential systemic seed-borne disease in barley worldwide. Barley is a major cereal crop in the Qinghai–Tibet Plateau, and barley production has been threatened by leaf stripe in this region, particularly in organic farming regions. Detecting the pathogen in infected barley seeds is crucial for managing barley leaf stripe. In this study, a loop-mediated isothermal amplification (LAMP) assay was developed to detect the pathogen based on primers designed based on the sequence of the pig 14 gene (GenBank: AJ277800) of P. graminea. The optimal concentrations of MgSO4, dNTPs, and enzymes in the LAMP reaction system were established as 10.0 mM, 1.0 mM, and 8 U in a 25 μL reaction volume, respectively. The established LAMP methods for detecting P. graminea were optimally performed at 63 °C for 70 min with high reliability. The minimum detection limit was 1 × 10−2 ng·μL−1 in the 25 μL reaction system. The specificity of LAMP for P. graminea was validated with eight fungal species. All DNA extracts from P. graminea-infected barley seeds with incubation, intact, and smashed treatments were applied in LAMP and confirmed to enable the detection of the pathogen. The LAMP assay in this study could facilitate the detection of P. graminea in barley seeds onsite, provide information for seed health certificates, and help decide on seed treatment in leaf stripe management.

Vitamin B12, an important cofactor involved in propionate formation, is synthesized exclusively by bacteria and archaebacteria. Humans need to intake vitamin B12 through food, and dairy products are generally the best source of vitamin B12. In the present study, the effects of vitamin B12 supplementation in diets on in vitro ruminal fermentation characteristics and microbial communities were investigated to provide a reference for increasing the vitamin B12 content in milk by dietary supplementation. A completely randomized design was carried out using the in vitro rumen culture technique, and 5 vitamin B12 dose levels (0, 0.5, 1.0, 2.0, and 4 mg/g of dry matter) were used. The results showed that vitamin B12 supplementation in diets decreased acetate: propionate ratio and butyrate concentration. The change in the acetate: propionate ratio can be attributed to the increased relative abundances of the Proteobacteria phylum and the Negativicutes class, both of which are involved in propionate metabolism. The decrease in butyrate concentration can likely be attributed to a reduction in relative abundance of species belonging to the Clostridia class, which are known as the predominant butyrate producers in the mammalian intestine. In addition, vitamin B12 supplementation in diets reduced the CH4 production by altering the species composition of the archaeal community. In conclusion, dietary supplementation of vitamin B12 resulted in rumen perturbation. In vivo studies should be conducted cautiously when evaluating the effects of vitamin B12 supplementation on the synthesis and absorption of it, as well as its content in milk. [ABSTRACT FROM AUTHOR]
