Objective:To observe the changes of arterial blood gas indexes in pigs with the free-field primary blast lung injury (PBLI) model, and to explore the value of arterial blood gas indexes in predicting moderate to severe PBLI.Methods:Nine adult healthy Landrace pigs were selected to construct the pig free-field PBLI model. Arterial blood samples were taken 15 minutes before the explosion (before injury) and 10, 30, 60, 120, and 180 minutes after the explosion (after injury). Arterial blood gas indexes and pulse oxygen saturation (SpO 2) were measured, compare the changes of blood gas analysis indexes and SpO 2 levels at different time points, and observe the changes of gross injury scores and pathological injury scores of lung tissue. Analyze the correlation between the blood gas indicators. Results:As time prolonged, at each time point, pH, arterial partial pressure of oxygen (PaO 2), and SpO 2 were lower than those before the injury, and blood lactic acid (Lac) and arterial partial pressure of carbon dioxide (PaCO 2) were higher than those before the injury. Compared with that before the injury, the pH value in the blood decreased significantly 10 minutes after the injury (7.39±0.06 vs. 7.46±0.02, P < 0.05), and the Lac increased significantly (mmol/L: 3.61±2.89 vs. 1.10±0.28, P < 0.05), and lasts until 180 minutes after injury (pH value: 7.37±0.07 vs. 7.46±0.02, Lac (mmol/L): 2.40±0.79 vs. 1.10±0.28, both P < 0.05); while PaO 2 and SpO 2 decreased significantly at 180 minutes after injury [PaO 2 (mmHg, 1 mmHg = 0.133 kPa): 59.40±10.94 vs. 74.81±9.39, P < 0.05; SpO 2: 0.75±0.11 vs. 0.89±0.08, P < 0.05], PaCO 2 increased significantly (mmHg: 56.17±5.38 vs. 48.42±4.93, P < 0.05). Correlation analysis showed that the gross injury score of lung blast injury animals was positively correlated with the pathological injury score ( r = 0.866, P = 0.005); PaO 2 and SpO 2 were positively correlated ( r = 0.703, P = 0.000); pH value and Lac were negative Correlation ( r = -0.400, P = 0.006); pH value is negatively correlated with PaCO 2 ( r = -0.844, P = 0.000). Conclusion:This study successfully established a large mammalian free-field PBLI model, arterial blood gas analysis is helpful for the early diagnosis of PBLI, whether SpO 2 can be used to evaluate the severity of lung injury remains to be further verified.

Objective:To develop a grading prediction model of traumatic hemorrhage volume based on deep learning and assist in predicting traumatic hemorrhage volume.Methods:A retrospective observational study was conducted based on the experimental data of pig gunshot wounds in the time-effect assessment database for experiments on war-traumatized animals constructed by the General Hospital of the Chinese People's Liberation Army. The hemorrhage volume data of the study population were extracted, and the animals were divided into 0-300 mL, 301-600 mL, and > 600 mL groups according to the hemorrhage volume. Using vital signs indexes as the predictive variables and hemorrhage volume grading as the outcome variable, trauma hemorrhage volume grading prediction models were developed based on four traditional machine learning and ten deep learning methods. Using laboratory test indexes as predictive variables and hemorrhage volume grading as outcome variables, trauma hemorrhage volume grading prediction models were developed based on the above fourteen methods. The effect of the two groups of models was evaluated by accuracy and area under the receiver operator characteristic curve (AUC), and the optimal models in the two groups were mixed to obtain hybrid model 1. Feature selection was conducted according to the genetic algorithm, and hybrid model 2 was constructed according to the best feature combination. Finally, hybrid model 2 was deployed in the animal experiment database system.Results:Ninety-six traumatic animals in the database were enrolled, including 27 pigs in the 0-300 mL group, 40 in the 301-600 mL group, and 29 in the > 600 mL group. Among the fourteen models based on vital signs indexes, fully convolutional network (FCN) model was the best [accuracy: 60.0%, AUC and 95% confidence interval (95% CI) was 0.699 (0.671-0.727)]. Among the fourteen models based on laboratory test indexes, recurrent neural network (RNN) model was the best [accuracy: 68.9%, AUC (95% CI) was 0.845 (0.829-0.860)]. After mixing the FCN and RNN models, the hybrid model 1, namely RNN-FCN model was obtained, and the performance of the model was improved [accuracy: 74.2%, AUC (95% CI) was 0.847 (0.833-0.862)]. Feature selection was carried out by genetic algorithm, and the hybrid model 2, namely RNN-FCN* model, was constructed according to the selected feature combination, which further improved the model performance [accuracy: 80.5%, AUC (95% CI) was 0.880 (0.868-0.893)]. The hybrid model 2 contained ten indexes, including mean arterial pressure (MAP), hematocrit (HCT), platelet count (PLT), lactic acid, arterial partial pressure of carbon dioxide (PaCO 2), Total CO 2, blood sodium, anion gap (AG), fibrinogen (FIB), international normalized ratio (INR). Finally, the RNN-FCN* model was deployed in the database system, which realized automatic, continuous, efficient, intelligent, and grading prediction of hemorrhage volume in traumatic animals. Conclusion:Based on deep learning, a grading prediction model of traumatic hemorrhage volume was developed and deployed in the information system to realize the intelligent grading prediction of traumatic animal hemorrhage volume.

OBJECTIVETo investigate relations between milk consumption and lactose intolerance (LI) in adults and to explore the effect of milk consumption on lactase activity.

METHODSTotal of 182 subjects aged 20-70 years were recruited and interviewed by questionnaires, and their accumulative cow's milk intake (AMI) was calculated. LI was evaluated by hydrogen breath test (HBT).

RESULTSA negative correlation was found between AMI and severity of observed LI symptom (r=-0.2884; P<0.05). Binary logistic regression analysis showed a negative correlation between LI and duration and frequency of milk consumption (OR, 0.317 and 0.465, respectively; both P<0.05) and a positive correlation between LI and amount of milk consumed per sitting (OR, 6.337; P<0.05).

CONCLUSIONLI is related to various milk consumption behaviors. Most Chinese adults with LI may tolerate moderate milk consumption <160 mL.

OBJECTIVE: To systematically evaluate the clinical effect of cultured milk products as adjunctive therapy in the anti- Helicobacter pylori (H. pylori) treatment.
 METHODS: The randomized controlled trials (RCT) and Quasi-randomized controlled clinical trials (Quasi-RCT), which were used to evaluate the efficacy and safety of eradicating H. pylori by fermented milk-based routine treatment, were searched and collected in Pubmed, Embase, CNKI (China National Knowledge Infrastructure), CBM (Chinese BioMedical Literature Database), Wangfang Database, VIP (VIP Citation Database) from establishment of these database to February 2015. The combined relative risk (RR) of H. pylori eradication rate and the rate of side effects were analyzed. Sub-group and sensitivity analysis was performed, and the publication bias was also tested. 
 RESULTS: A total of 9 studies including 1 644 cases were identified. The H. pylori eradication rate was 79.5% in fermented milk products combined with routine therapy, and 67.0% in routine therapy. The combined RR of H. pylori eradication rate was 1.186 (95% CI 1.118-1.257), and the combined RR of total side effects was 0.706 (95% CI 0.373-1.340).
 CONCLUSION Cultured milk products as adjunctive therapy is effective in improving the eradication rate during eradication therapy for H. pylori. However, it could not effectively decrease the risk of side effects.

OBJECTIVE To study the effects of bergapten in the treatment of liver fibrosis and its mechanism based on serum metabolomics. METHODS Forty mice were divided into normal control group （0.5% carboxymethyl cellulose sodium solution）， model group （0.5% carboxymethyl cellulose sodium solution）， and BP low-dose and high-dose groups （50， 100 mg/kg）， with 10 mice in each group. Except for the normal control group， the other three groups were all treated with carbon tetrachloride to induce liver fibrosis model； they were given relevant medicine/solution intragastrically， once a day， for consecutive 8 weeks. After the last medication， the levels of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in serum were detected， and liver pathological changes were observed； the expressions of α-smooth muscle actin （α-SMA） and Collagen Ⅰ were detected in liver tissue； the serum of the mice was collected for metabolomics analysis. RESULTS Compared with the model group， serum levels of ALT and AST and protein expressions of α-SMA and Collagen Ⅰ in liver tissue were decreased significantly in BP high-dose and low-dose groups （P＜0.05）， while liver fibrosis was improved significantly. Meanwhile， metabolomics analyses showed that there were a total of 175 serum differential metabolites in the BP high-dose group and model group， of which 18 substances were upregulated and 157 substances were downregulated； the main metabolic pathways involved in bergapten intervention were pyrimidine metabolism， butanoate metabolism， fatty acid synthesis， tyrosine metabolism， β-alanine metabolism， nicotinic acid and nicotinamide metabolism， glutathione metabolism， etc. CONCLUSIONS BP is effective in the treatment of liver fibrosis by regulating pyrimidine metabolism， butanoate metabolism， glutathione metabolism and so on in rats with liver fibrosis.
