摘要：

Pulmonary alveolar microlithiasis is a rare disease characterized by intra-alveolar presence of microliths. This study reports an interesting case of pulmonary alveolar microlithiasis and provides a systematic review of cases reported from India. A 23-year-old female presented with a history of cough, wheeze, chest pain, and episodic wheeze for five months. Pulmonary function tests demonstrated an obstructive pattern, and chest X-ray showed fine micronodular opacities predominantly involving the middle and lower zones of both lungs. Transbronchial lung biopsy revealed the diagnosis. She responded well to inhaled steroid therapy. A systematic review of literature was performed and identified 73 cases of pulmonary alveolar microlithiasis reported from India. The mean (SD) age of the patients was 28.8 (14.9) years, with an almost equal male:female ratio. Many patients were asymptomatic at presentation. Breathlessness and cough were the most common symptoms, and the disease progressed into respiratory failure associated with cor pulmonale. About one-third of the cases were initially misdiagnosed and treated as pulmonary tuberculosis. Extra-pulmonary manifestations and co-morbidities were also evident in our series. This systematic review helps to determine epidemiological and clinical characteristics of pulmonary alveolar microlithiasis. Further research is needed to elucidate the etiopathogenesis, diagnosis, and therapeutic options, which are beneficial in developing and identifying cost-effective treatment for pulmonary alveolar microlithiasis.

Recovery of rare and precious metals from urban mines—A review

Mengmeng Wang, Quanyin Tan, Joseph F. Chiang, Jinhui Li

《环境科学与工程前沿（英文）》 2017年第11卷第5期 doi: 10.1007/s11783-017-0963-1

摘要： Urban mining is essential for continued natural resource extraction. The recovery of rare and precious metals (RPMs) from urban mines has attracted increasing attention from both academic and industrial sectors, because of the broad application and high price of RPMs, and their low content in natural ores. This study summarizes the distribution characteristics of various RPMs in urban mines, and the advantages and shortcomings of various technologies for RPM recovery from urban mines, including both conventional (pyrometallurgical, hydrometallurgical, and biometallurgical processing), and emerging (electrochemical, supercritical fluid, mechanochemical, and ionic liquids processing) technologies. Mechanical/physical technologies are commonly employed to separate RPMs from nonmetallic components in a pre-treatment process. A pyrometallurgical process is often used for RPM recovery, although the expensive equipment required has limited its use in small and medium-sized enterprises. Hydrometallurgical processing is effective and easy to operate, with high selectivity of target metals and high recovery efficiency of RPMs, compared to pyrometallurgy. Biometallurgy, though, has shown the most promise for leaching RPMs from urban mines, because of its low cost and environmental friendliness. Newly developed technologies—electrochemical, supercritical fluid, ionic liquid, and mechanochemical—have offered new choices and achieved some success in laboratory experiments, especially as efficient and environmentally friendly methods of recycling RPMs. With continuing advances in science and technology, more technologies will no doubt be developed in this field, and be able to contribute to the sustainability of RPM mining.

Rare tumors: a blue ocean of investigation

《医学前沿（英文）》 2023年第17卷第2期页码 220-230 doi: 10.1007/s11684-023-0984-z

摘要： Advances in novel drugs, therapies, and genetic techniques have revolutionized the diagnosis and treatment of cancers, substantially improving cancer patients’ prognosis. Although rare tumors account for a non-negligible number, the practice of precision medicine and development of novel therapies are largely hampered by many obstacles. Their low incidence and drastic regional disparities result in the difficulty of informative evidence-based diagnosis and subtyping. Sample exhaustion due to difficulty in diagnosis also leads to a lack of recommended therapeutic strategies in clinical guidelines, insufficient biomarkers for prognosis/efficacy, and inability to identify potential novel therapies in clinical trials. Herein, by reviewing the epidemiological data of Chinese solid tumors and publications defining rare tumors in other areas, we proposed a definition of rare tumor in China, including 515 tumor types with incidences of less than 2.5/100 000 per year. We also summarized the current diagnosis process, treatment recommendations, and global developmental progress of targeted drugs and immunotherapy agents on the status quo. Lastly, we pinpointed the current recommendation chance for patients with rare tumors to be involved in a clinical trial by NCCN. With this informative report, we aimed to raise awareness on the importance of rare tumor investigations and guarantee a bright future for rare tumor patients.

Arsenic trioxide induced rhabdomyolysis, a rare but severe side effect, in an APL patient: a case report

null

《医学前沿（英文）》 2017年第11卷第2期页码 284-286 doi: 10.1007/s11684-017-0514-y

摘要：

Arsenic trioxide (ATO), a component of the traditional Chinese medicine arsenic sublimate, promotes apoptosis and induces leukemic cell differentiation. Combined with all-trans-retinotic acid (ATRA), ATO has become the first-line induction therapy in treating acute promyelocytic leukemia (APL). The most common side effects of ATO include hepatotoxicity, gastrointestinal symptoms, water-sodium retention, and nervous system damage. In this report, we present a rare side effect, rhabdomyolysis, in a 68-year-old female APL patient who was treated with ATO. After taking 10 mg ATO daily for 6 days, she presented shortness of breath, myodynia, elevated creatine kinase, and acute renal insufficiency. This report describes the first case of ATO-induced rhabdomyolysis.

摘要： Laparoscopic liver surgery has been increasingly used for the treatment of pediatric liver diseases over the past decade due to the development of special laparoscopic instruments and improvements in the technique. A number of factors are considered when electing to undergo the surgical process, including age, type of liver disease, and so on. Especially in children with liver masses, the number of trocars used and the position of their placement must be carefully designed to achieve successful outcomes. In the current review, the application of various laparoscopic instruments and the methods used for the laparoscopic treatment of liver diseases in children over the past decade are summarized.

Prevalence of cardiovascular diseases in China

Jun-Jie XIAO MD, Yi-Han CHEN MD, PhD,

《医学前沿（英文）》 2010年第4卷第1期页码 16-20 doi: 10.1007/s11684-010-0007-8

摘要： Cardiovascular diseases (CVD) cause one third of all deaths in China, and the number is anticipated to double by 2020. They also greatly result in disability and adjusted life year loss. The prevalence of CVD has become a new burden for China, due to an aging population, smoking, and changes in dietary habits and lifestyles. As the largest developing country, China needs to tailor her own national policies for managing CVD with full consideration of epidemiology, local needs, and affordability. Smoking cessation, increased physical activity, control of hypertension and hypercholesterolemia, and maintenance of a “traditional Chinese” diet should be important strategies for reducing the burden of CVD in China. Health officials in China should take their responsibilities to implement educational and preventive measures seriously.

Cultural differences define diagnosis and genomic medicine practice: implications for undiagnosed diseases

null

《医学前沿（英文）》 2013年第7卷第3期页码 389-394 doi: 10.1007/s11684-013-0281-3

摘要：

Despite the current acceleration and increasing leadership of Chinese genetics research, genetics and its clinical application have largely been imported to China from the Occident. Neither genetics nor the scientific reductionism underpinning its clinical application is integral to the traditional Chinese worldview. Given that disease concepts and their incumbent diagnoses are historically derived and culturally meaningful, we hypothesize that the cultural expectations of genetic diagnoses and medical genetics practice differ between the Occident and China. Specifically, we suggest that an undiagnosed diseases program in China will differ from the recently established Undiagnosed Diseases Program at the United States National Institutes of Health; a culturally sensitive concept will integrate traditional Chinese understanding of disease with the scientific reductionism of Occidental medicine.

Nan XIANG, Weikun HU, Jing YUAN, Guigang LI, Haixia LIU

《医学前沿（英文）》 2009年第3卷第1期页码 113-117 doi: 10.1007/s11684-009-0001-1

摘要： The lacrimal endoscope is applied to the diagnosis and therapy of the disorders of the lacrimal system in combination with laser or micro drills under orthophoria. The changes of mucous membranes, the characteristics of pathological changes and the predilection sites of lacrimal system diseases were initially approached. One hundred and forty six pairs of eyes of 128 patients with lacrimal system disease were observed by the lacrimal endoscope in the Ophthalmology Department of Tongji Hospital from June 2006 to March 2007. The dynamic changes in mucous membranes, lesion sites, secreted substances and formation of membrane could be observed under orthophoria. Combined with laser or micro drill, the endoscope was applied to the therapy of lacrimal system disorders and the difference before and after the treatment was observed. Results are as follows: (1) The examination and therapy using the lacrimal endoscope were completed under topical anesthesia in 122 patients, and 6 patients of neonatorum dacryocystitis were examined and treated under general anaesthesia. All patients reported painless. (2) Sharp images of the lacrimal system were obtained by the endoscope. Normal lacrimal mucosal membrane was smooth and light pink, expanded and unobstructed during irrigation. In chronic dacryocystitis patients, the inhomogeneous colour of mucosal membranes was red and white, with different degrees of fibrotic membranes at the superior, middle and inferior parts of the nasolacrimal canals and secreted substances at sac could be observed. The lacrimal ducts could not be expanded and obstructed during irrigation. The patients with lacrimal system obstruction had different extents of membrane formation, and stenosis or complete obstruction of the lacrimal duct could be observed, and the corresponding mucosal membrane was not smooth which could not be expanded and obstructed during irrigation. (3) After the treatment by the endoscope combined with laser or micro drill, the major proliferation of the membrane disappeared and the lacrimal duct was unobstructed during irrigation. The cure rate and effective rate were 80.1% and 93.1%, respectively. The lacrimal endoscope is a new method in the diagnosis of lacrimal system diseases. Through a combination with laser or micro drill to carry out the therapy under orthophoria, it will bring a great change to the diagnosis and therapy of lacrimal system diseases.

Rare-earth separation based on the differences of ionic magnetic moment via quasi-liquid strategy

《化学科学与工程前沿（英文）》 2023年第17卷第10期页码 1584-1594 doi: 10.1007/s11705-022-2189-4

摘要： The separation of rare earth elements is particularly difficult due to their similar physicochemical properties. Based on the tiny differences of ionic radius, solvent extraction has been developed as the “mass method” in industry with hundreds of stages, extremely intensive chemical consumption and large capital investments. The differences of the ionic magnetic moment among rare earths are greater than that of ionic radius. Herein, a novel method based on the large ionic magnetic moment differences of rare earth elements was proposed to promote the separation efficiency. Rare earths were firstly dissolved in the ionic liquid, then the ordering degree of them was improved with the Z-bond effect, and finally the magnetic moment differences between paramagnetic and diamagnetic rare earths in quasi-liquid system were enhanced. Taking the separation of Er/Y, Ho/Y and Er/Ho as examples, the results showed that Er(III) and Ho(III) containing ionic liquids had obvious magnetic response, while ionic liquids containing Y(III) had no response. The separation factors of Er/Y and Ho/Y were achieved at 9.0 and 28.82, respectively. Magnetic separation via quasi-liquid system strategy provides a possibility of the novel, green, and efficient method for rare earth separation.

Assessment of leaching behavior and human bioaccessibility of rare earth elements in typical hospital

Chunfeng Wang, Guanfei Chen, Yanchen Zhu, Dan Yao, Wanfeng Wang, Lianjun Wang

《环境科学与工程前沿（英文）》 2017年第11卷第6期 doi: 10.1007/s11783-017-0946-2

摘要： Leaching behavior and gastrointestinal bioaccessibility of rare earth elements (REEs) from hospital waste incineration (HWI) fly and bottom ash samples collected from Beijing and Nanjing Cities were assessed. In the same ash sample, the leaching concentrations of individual REEs determined by the Toxicity Characteristic Leaching Procedure (TCLP) were higher than those detected by the European standard protocol (EN-type test), thereby suggesting that the low pH value of leaching solution was an important factor influencing the leachability of REE. The REE bioaccessibility results, which were evaluated using the physiologically based extraction test (PBET), indicated that REEs were highly absorbed during gastric phase by dissolution; and subsequently precipitated and/or re-adsorbed in small intestinal phase. The relative amounts of the total REEs extracted by the TCLP method, EN-type test and PBET test were compared. In addition to the pH value of extraction solutions, the chelating role of REEs with organic ligands used in the PBET method was also an important parameter affecting REE adsorption in human body. Additionally, this study showed that REEs were extracted by these methods as concomitants of heavy metals and anions (NO , F , SO , and Cl ) from HWI ash, which probably caused the remarkably complex toxicity on human body by the exposure pathway.
