Primary blast lung injury is an acute lung injury caused by the direct impact of explosive shock wave acting on the lung;the serious case can develop acute respiratory distress syndrome,which is one of the leading causes of mortality in blast injury personnel.The pathophysiological characteristics of primary lung blast injury are relatively clear:rupture of the alveolar capillaries and subsequent intrapulmonary haemorrhage and edema,accompanied by oxidative stress,apoptosis,inflammatory reaction and other physiological processes.However,the molecular mechanism needs to be further studied.This paper focuses on the research progress of phosphatidylinositol 3-kinase/protein kinase,nuclear factor κB,mitogen-activated protein kinase and other signaling pathways in the research of primary blast lung injury.

The clinical manifestations, biochemical parameters and imaging examination, genetic test results, and treatment of 3 cases of X-linked adrenoleukodystrophy(X-ALD) patients were reviewed and analyzed, and the structure of adrenoleukodystrophy protein(ALDP) was analyzed. All 3 patients were male. Patients 1 and 2 were childhood cerebral ALD(CCALD), patients 3 was adrenomyeloneuropathy(AMN), and all of them were misdiagnosed at early stage. Brain magnetic resonance imaging(MRI), and hematologic examinations showed the neurological demyelination of X-ALD, adrenocortical insufficiency, and accumulation of very long chain fatty acids(VLCFAs). Sequencing of ABCD1 gene revealed 3 new pathogenic mutations[c.910delins22(p.A304delins8), c. 887A>C(p.Y296S), and c. 1451_1481del(p.P484fs)], which affected the key structure of ALDP and led to the disease. Patients 1 and 2 received hematopoietic stem cell transplantation, and their condition continued to progress after surgery. Patient 3 was in stable condition. The misdiagnosis rate of X-ALD is high, clinicians should be vigilant. In this study, 3 new mutations were found, which expanded the ABCD1 gene mutation spectrum in patients with X-ALD. It is important to note that early identification and early diagnosis of X-ALD should be made to reduce misdiagnosis and mistreatment.

Radiation-induced lung injury is a common complication of thoracic malignant tumor radiotherapy and severe nuclear accident injury. Currently, there is no effective treatment on this injury. Mesenchymal stem cells (MSCs) are a group of cells with multi-directional differentiation potential and they can protect lung tissue from radiation damage by homing to the injured site and differentiating to the damaged tissues, secreting cytokines and immune regulation. Further, the genetically modifying mesenchymal stem cells have not only the main characteristics of MSCs, but also can efficiently and stably express or knock down a certain of target genes, thereby enhancing or reducing the sensitivity of mesenchymal stem cells to various physiological stimulus and enhancing its therapeutic effect in radiation-induced lung injury, providing new ideas and new strategies for clinical treatment. This paper reviewed the relevant research progress in recent years.

Objective:To explore the effect of paradoxical intention training on the sleep quality, negative emotion and quality of life of elderly patients with obstructive sleep apnea syndrome (OSAS) .Methods:From March 2018 to February 2020, convenience sampling was used to enroll 130 elderly OSAS patients admitted to the First Affiliated Hospital of Zhengzhou University. Patients were randomly divided into control group and observation group, with 65 cases in each group. Control group implemented routine nursing, while observation group conducted paradoxical intention training based on routine nursing. Pittsburgh Sleep Quality Index (PSQI) , Hospital Anxiety and Depression Scale (HADS) , Calgary Sleep Apnea Quality of Life Index (SAQLI) were used before and after the intervention to compare the sleep quality, psychological status and quality of life between two groups.Results:After one week of intervention, the score of PSQI, anxiety subscale (HADS-A) , depression subscale (HADS-D) of observation group were (7.08±2.70) , (6.25±1.20) and (6.34±1.24) respectively, lower than those of control group, the differences were statistically significant ( t=4.871, 9.439, 8.754; P<0.01) . After the intervention, the total score of SAQLI in observation group was (4.87±0.35) and that in control group was (4.22±0.25) , the difference was statistically significant ( t=12.184, P<0.01) . Conclusions:Paradoxical intention training can help improve the sleep quality, psychological conditions and quality of life of elderly OSAS patients.

The resource of rare and endangered medicinal plant Swertia mussotii Franch. in Tibet, Qinghai and Sichuan province were surveyed by ways of documents, interview, quadrat and market investigation. The results indi-cated that Swertia mussotii Franch. mainly distributed in Zuogong and Mangkang of Tibet, Yushu of Qinghai province, Shiqu, Daofu, Kangding, Maerkang, Jinchuan and Xiaojin of Sichuan province. According to the height above sea level, the distribution altitude was from 2 300 m (Kangding of Sichuan province) to 3 900 m (Mangkang of Tibet). There are distributions of Swertia mussotii Franch. within the scope of 2 600 m. The illumination, water, soil, temperature and altitude had significant influence on the distribution, growth and reserve of Swertia mussotii Franch. from different angles. In recent years, there was huge increase of market requirement in Swertia mussotii Franch. which were used in Tibetan medicine Zangyinc he n. Excess collection was the primary cause of rapid decreasing in resource of Swertia mussotii Franch.. It was suggested to strengthen the management of rational collection, as well as to accelerate the development of cultivation and production.

OBJECTIVETo determine the content of podophyllotoxin and total lignans in Sinopodophyllum emodi Ying from different areas and evaluate the resource utilization of this endangered medicinal plant.

METHODHPLC and UV spectrophotometry were used to determine the content of podophyllotoxin and total lignans in 126 samples from different habitats and the total lignans content was determined by the reference wavelength method.

RESULTAccording to the results, the highest content was determined from the samples from Yongdeng Nature Reserve in Gansu province, and the lowest ones was found in the samples from Tibet. The former's podophyllotoxin and total lignans contents were 7.40% and 20.66%, respectively, which were 19 times and 4 times more than those of the latter. The content of podophyllotoxin and total lignans in S. emodi were significantly positively related, meanwhile, samples from both low altitude and high latitude showed the higher content.

CONCLUSIONThe two determination methods are simple, rapid, accurate and repeatable. It is more scientific and rational to evaluate the resource utilization of S. emodi with two indicators, those are the content of podophyllotoxin and the content of total lignans. This paper is instructive to the collection of wild resources and the establishment of production bases.

The resource of Sinopodophyllum emodi in Tibet, Qinghai, Gansu, Sichuan and Yunnan province were surveyed by the ways of documents, interview, quadrat and market investigation. The results indicated that S. emodi were mainly distributed in central part from Taibai Shan of Shanxi province along the middle and high mountain on either side of Hengduan mountain which from north to south and in Tibetan plateau of China, the suitable eco-environment of S. emodi was dominated by valleys, wet forests and low bush-woods vegetation which comparatively dry on plateau with the altitude focused on 1 5004 500 meters, and the distribution density of simple alpine meadow was relatively lower. Illumination, water, soil, temperature and altitude had significant influences on the growth, distribution and reserves of S. emodi from different angles. In recent years, there was sharp increase of market requirement in Xiaoyelian (fruit) which were used in Tibetan medicine and the underground part which was used for the extraction of podophyllotoxin, excess collection of the underground part was the primary cause of the rapid decreasing resource of S. emodi. It is suggested that the management of rational collection should be strengthen and the development of culturing and production should be meanwhile accelerated.
