22 patients with acute myocardial infarction (AMI) under went early exercise testing (EET)(mean 12.50±4.39 days after MI) in our study. The positive rate of testing was 45.45%. The maximal ratepressure product (SBP×HR) and peak metabolic equivalent were 2782±776 bpm.kPa and 4.96 ±1.20METs. Following up 3 months to 2.5 years (1.33±0.84 years), we found that the occurrence of heart events in the positive EET group (EET-P) was more than in the negative EET group (EET-N) (X2=4.77, P<0.05).Time of return to work and housework in EET-P was earlier than EET-N. About time and ratio of return to work and housework, the EET group was higher and earlier than no EET(N-EET) group. On the other hand,sexual activity of EET was recovered to a certain degree and ma jority could do some physical training- The results would be showed that EET could improve the quality of life in the patients with AMI.

Objective To investigate the effect of C-erbB-2 shRNA on chemosensitivity of mouse lung adenocarcinoma cells and its mechanism,and to find new therapy method for non-small cell lung cancer,especial lung adenocarcinoma.Methods The mouse lung adenocarcinoma Lewis cells were cultured regularly and divided into non-transfected group, pGPU6/RFP/Neo-shNC group and pGPU6/RFP/Neo-erbB-2 group. The plasmids were synthesized and transfected into Lewis cells in each group by Lipofectamine 2000.The expression levels of C-erbB-2 mRNA and protein in the cells in various groups were tested by RT-PCR and Western blotting method, respectively. The Lewis cells were divided into non- transfected group, pGPU6/RFP/Neo-shNC group, carboplatin group, pGPU6/RFP/Neo-erbB-2 group, pGPU6/RFP/Neo-shNC+carboplatin group and pGPU6/RFP/Neo-erbB-2+ carboplatin group. The apoptotic rates of the cells in each group were detected by flow cytometry;the expression levels of Bcl-2 and Bax proteins in each group were determined by Western blotting method.Results The expression levels of C-erbB-2 mRNA and protein in pGPU6/RFP/Neo-erbB-2 group were lower than those in non-transfected group and pGPU6/RFP/Neo-shNC.The apoptotic rate of the cells in pGPU6/RFP/Neo-erbB-2+carboplatin group was the highest in all of the groups (P<0.01);compared with the others, the expression of Bax protein in pGPU6/RFP/Neo-erbB-2+carboplatin group was increased, while the expression level of Bcl-2 protein was decreased.Conclusion C-erbB-2 shRNA can increase the Lewis cells’sensitivity to carboplatin.The mechanism may be that it can enhance the Lewis cells’apoptosis induced by carboplatin through increasing the expression of Bax protein and decreasing the expression of Bcl-2 protein.

OBJECTIVE:
To explore the impact of upper airway expansion surgery on the blood pressure of hypertension patients with upper airway obstruction.
METHOD:
Clinical data of 45 cases of hypertension patients with nasal obstruction who were underwent upper airway expansion surgery. The morning sitting blood pressure of patients were recorded. All of the patients were underwent nasal expansion surgery and 11 cases with obstructive sleep apnea hypopnea syndrome were combined with H-uvulopalatopharyngoplasty.
RESULT:
Blood pressure of all 45 cases were apparently reduced in 12 months after the operations [systolic blood pressure (157.38 +/- 15.15) mmHg to (132.18 +/- 8.43) mmHg, diastolic blood pressure (95.42 +/- 9.28) mmHg to (82.31 +/- 5.88)mmHg], in which 9 cases with type I hypertension were lowered to normal pressure. Results had statistical difference between pre-operation and post-operation (P < 0.01).
CONCLUSION
Upper airway expansion surgery (including nasal and pharynx cav ity) can help lower blood pressure of hypertensive patients with nasal obstruction. Post-operative results were better than H-uvulopalatopharyngoplasty only.

OBJECTIVETo investigate the feasibility of establishing an integrated regional network for ST-segment elevation myocardial infarction (STEMI) care in China and evaluate the implementation effect of this network.
METHODSBased on real-time electrocardiogram transmission technology, we established an integrated regional network for STEMI care (IRN-STEMI) with Xiamen Heart Center as the core center, 120 Emergency Systems, PCI-capable hospitals and other community health units as core elements of this network. Reperfusion treatment data of Xiamen Heart Center including the number of patients receiving primary percutaneous coronary intervention (PCI), the mean first medical contact to balloon (FMC-to-B) time, the mean door to balloon (D-to-B) time, the mean length of hospital stay, the mean medical cost and in-hospital mortality were compared before (n = 165) and at 1 year after the built-up of IRN-STEMI (n = 343).
RESULTSCompared to pre-IRN-STEMI era, primary PCI ratio (84.5% (290/343) vs. 75.5% (185/245)) were significantly increased post establishment of IRN-STEMI within the network (P = 0.06). STEMI patients admitted in Xiamen Heart Center was significantly increased from 165 to 256, the annual mean FMC-to-B time ((110.3 ± 34.0)min vs. (137.9 ± 58.5) min, P < 0.01) and D-to-B ( (76.5 ± 33.0) min vs. (107.3 ± 38.0) min, P < 0.01) , as well as the mean medical cost were significantly decreased ( (51 398 ± 22 100) RMB vs. (56 970 ± 24 593) RMB, P < 0.05), while the mean length of hospital stay ((9.0 ± 4.3)d vs. (9.7 ± 4.8)d, P > 0.05) and in-hospital mortality (3.1% (8/256) vs. 3.0% (5/165) , P > 0.05) remained unchanged before and after the setting of IRN-STEMI in Xiamen Heart Center.
CONCLUSIONEstablishment of an integrated regional network system for STEMI patients in China is feasible. With collaboration of qualified heart center, EMS and PCI-capable and non-PCI capable local hospitals, establishment of IRN-STEMI effectively increased the ratio of primary PCI for STEMI patients, it also significantly shortened the FMC-to-B and D-to-B time, decreased mean medical cost, thus, the regional IRN-STEMI network might be an effective working system for improving the medical care for STEMI patients.

OBJECTIVE:
To understand the distribution of allergens in patients with allergic rhinitis (AR) in Quanzhou, for the diagnosis, prevention and treatment.
METHOD:
Twenty standardized allergen underwent skin prick testing (skin prick test, SPT) were used for 1236 patients with suspected AR patients in Quanzhou, and the different age, gender and severity in patients with allergen distribution differences of positive rate were analyzed.
RESULT:
The top 5 allergens with positive skin tests were D. pteronyssinus (66.7%), D. farinae (65.5%), Blattodea (32.8%), Sea crab (18.2%), and Sea lobster (16.8%). The positive rate of SPT in the minor groups and adult groups had significant difference (P < 0.05). Gender difference between the positive rate of SPT had no significant difference (P > 0.05). There was significant difference between the positive rate in patients with a family history and history of asthma and patients without above two history (P < 0.05).
CONCLUSION
Dust Mite, Blattodea, Sea crab. Sea lobster are the most important allergens in quanzhou. Different ages of the patients with SPT positive rates vary, a family history, history of asthma patients with positive rate is higher than patients without a family history of asthma history, high positive rate.

Brain decoding based on functional magnetic resonance imaging has recently enabled the identification of visual perception and mental states. However, due to the limitations of sample size and the lack of an effective reconstruction model, accurate reconstruction of natural images is still a major challenge. The current, rapid development of deep learning models provides the possibility of overcoming these obstacles. Here, we propose a deep learning-based framework that includes a latent feature extractor, a latent feature decoder, and a natural image generator, to achieve the accurate reconstruction of natural images from brain activity. The latent feature extractor is used to extract the latent features of natural images. The latent feature decoder predicts the latent features of natural images based on the response signals from the higher visual cortex. The natural image generator is applied to generate reconstructed images from the predicted latent features of natural images and the response signals from the visual cortex. Quantitative and qualitative evaluations were conducted with test images. The results showed that the reconstructed image achieved comparable, accurate reproduction of the presented image in both high-level semantic category information and low-level pixel information. The framework we propose shows promise for decoding the brain activity.
