AIM:To investigate the effects of N-acetylcysteine (NAC) on acute lung injury induced by H9N2 swine influenza virus ( SIV) in mice.METHODS: BALB/c mice were used to establish the animal model of acute lung injury by nasal inoculation of H9N2 SIV.The mice were divided into control group (without SIV infection), H9N2 SIV group (inoculation of H9N2 SIV) and NAC group (inoculation of H9N2 SIV plus pretreatment with NAC).The pulmonary edema was evaluated by determining the lung wet weight /dry weight ( W/D) ratio.The pathological changes of the lung tis-sues were observed .The concontrations of TNF-α, IL-1βand IL-6 in bronchoalveolar lavage fluid ( BALF) were meas-ured.The virus titer, T-SOD activity, MPO activity and MDA content in the homogenate of the lung tissues were detected . RESULTS:Treatment with NAC decreased the morality of infected mice , and significantly prolonged the survival time of infected mice .The pathological changes of the lung tissues , the lung W/D ratio and the lung index were relieved when SIV infected the mice treated with NAC .Treatment with NAC significantly decreased the infiltration of inflammatory cells inclu-ding macrophages, lymphocytes and neutrophils in the BALF .The levels of TNF-α, IL-6, IL-1βand MDA and the activity of MPO were also decreased.Treatment with NAC also significantly increased the T-SOD activity.CONCLUSION: The protective effect of NAC on the acute lung injury mouse model is related to suppression of the oxidative stress and inflamma -tory responses .

Objective: To investigate the effects of hinokitiol on the proliferative inhibition and apoptosis induction in human clear cell renal cancer 786-O cells. Methods:CCK-8 assays were performed to analyze the effects of hinokitiol on the proliferation of 786-O cells. The apoptosis rate was determined by flow cytometry. EGFP-LC3 microscopy assays were performed to assess the autoph-agy flux. Cleaved Caspase-3, LC3, and P62 were detected by Western blot. Results: Hinokitiol could inhibit the proliferation of the 786-O cells and could induce cell apoptosis via Caspase pathway. Hinokitiol induced the autophagy of 786-O cells, increased LC3 ex-pression, and downregulated P62 expression. Conclusion: Hinokitiol can inhibit the proliferation of 786-O cells and can induce cell apoptosis via autophagy induction.

It's important that the university teachers apply proper linguistic strategies in the Traditional Chinese medicine courses for foreign students,which can reduce the non-native language ability limitation to teaching effect to a certain extent,which can let students better understand and grasp the contents.This paper summarize the influence of linguistic strategies on teaching effect,such as signposting,signalling importance,back channeling,repetition,questioning,commenting,which is the important foundation and powerful guarantee of ideal teaching effects of EMI.

With the development of the internationalization of Chinese medicine education,higher requirements are demanded for the faculty of foreign students.How to explore a suitable way of teaching foreign students to study TCM is the problem for all the foreign education teachers.Based on the concept of Gamification,we apply the game elements or mechanism effectively in teaching which can active the classroom atmosphere,improve students' interest and enhance the effect of learning.

Purpose To investigate the clinicopathologic features,molecular changes,treatment and prognosis of pulmo-nary artery intimal sarcoma.Methods Ten cases of pulmonary artery intimal sarcoma were collected and the clinical features analyzed,by using HE,immunohistochemistry EnVision meth-od,FISH,and review of relevant literature.Results There were 4 males and 6 females,with a male to female ratio of 1∶1.5.The patients were 33-75 years old with an average age of 55.7 years.The main clinical symptoms were chest tightness,shortness of breath(6/10),chest pain(5/10)and cough(3/10),hemoptysis(2/10),syncope(1/10),heart murmur(1/10).1 patient had a history of bilateral breast cancer,bilateral papillary thyroid carcinoma and invasive lung adenocarcinoma,1 patient had bilateral breast cancer and 1 patient had pulmonary embolism and cardiac myxoma.Preoperative imaging showed pulmonary embolism or lung tumor.Histological morphology showed that the tumor cells were fusiform or epithelioid,with ob-vious atypia.Some tumors differentiated into rhabdomyosarco-ma,angiosarcoma and leiomyosarcoma,and giant cells were seen in 2 cases.The tumor lacked specific immune markers,and the tumor cells expressed vimentin,Fli-1,SMA,MyogD1,Myoglobin,BCL-2,ERG,etc.Ki-67 proliferation index was a-bout 30%-70%.Fluorescence in situ hybridization was used to detect MDM2(4/5)and CDK4(1/1).All cases received surgical treatment,7 cases were followed up from 1 month to 17 months,and 4 cases of them had recurrence or distant metasta-sis.Conclusion Pulmonary artery intimal sarcoma is rare,without specific immune markers and with complicated gene changes.There is no standard treatment,and the prognosis is poor.

A number of studies have indicated that disorders of consciousness result from multifocal injuries as well as from the impaired functional and anatomical connectivity between various anterior forebrain regions. However, the specific causal mechanism linking these regions remains unclear. In this study, we used spectral dynamic causal modeling to assess how the effective connections (ECs) between various regions differ between individuals. Next, we used connectome-based predictive modeling to evaluate the performance of the ECs in predicting the clinical scores of DOC patients. We found increased ECs from the striatum to the globus pallidus as well as from the globus pallidus to the posterior cingulate cortex, and decreased ECs from the globus pallidus to the thalamus and from the medial prefrontal cortex to the striatum in DOC patients as compared to healthy controls. Prediction of the patients' outcome was effective using the negative ECs as features. In summary, the present study highlights a key role of the thalamo-basal ganglia-cortical loop in DOCs and supports the anterior forebrain mesocircuit hypothesis. Furthermore, EC could be potentially used to assess the consciousness level.
