Objective:To observe the pulmonary apoptosis resulted from ischemia reperfusion lung injury in rats. Methods: Forty male SD rats, weighing 300 350 g,were randomly divided into 8 groups: 6 ischemia reperfusion group,simple ischemia group and control group( n =5).An in situ ischemia reperfusion lung injury rat model was established. Apoptotic cells were detected by the terminal deoxynucleotidyl transferase mediate dUTP nick end labelling (TUNEL) technique and the apoptotic DNA fragments by pulmonary DNA electrophoresis. Electron microscopy was performed to verify the morphologic changes of apoptosis. Results: Obvious apoptosis of pneumocytes occurred early after(30 min) ischemia reperfusion lung injury, with the peak on 2 h after reperfusion, and there were no significant differences 12 h after reperfusion compared with control group. There was a slight but no statistically significant elevation of apoptotic pneumocytes number in simple ischemia group compared with controls. Conclusion: The result indicates that apoptosis may contribute significantly to ischemia reperfusion lung injury.

Objective To study the clinical effect of qi supplementation combined with rehabilitation on the severity of fatigue after ischcmic stroke in patients with qi deficiency. Methods Ninety ischemic stroke patients with qi deficiency were randomly divided into 3 groups of 30. The treatment group was treated with an oral decoction of qi-supplementing Chinese medicine and also rehabilitation. The Western medicine control group was treated with a Chinese medicine placebo, Western medicine and rehabilitation. The blank control group was treated with the Chinese medicine placebo and rehabilitation. All groups were evaluated using a stroke-specific quality of life scale ( SSQOL) and a fatigue severity scale (FSS) before and 4 weeks after treatment. Results After treatment, the average SS-QOL and FSS scores had improved significantly compared with those before treatment, especially in the two treatment groups. There was a significant difference between the treatment group and the Western medicine control group,and between the treatment group and the blank control group on both scales. There was also a significant difference between the Western medicine control group and the blank control group in terms of SS-QOL scores, but not FSSscores. Conclusion All 3 treatments alleviated fatigue in ischemic stroke patients with a qi deficiency. Qi supplementation combined with rehabilitation was the most effective, followed by Western medicine combined with rehabilitation.

ObjectiveTo explore the value of expanded radical resection for gallbladder cancer located respectively at body and bottom of the gallbladder and at the neck.MethodsIn this study,91 cases of gallbladder cancer were macropathologically divided into two groups, one with the lesion at the body and bottom of the gallbladder and the other at the neck, survival analysis was made accordingly. Three different kinds of resection were performed: the expanded radical resection, the standard radical resection and palliative operation.ResultsThe overall median survival rate of patients undergoing expanded radical operation was significantly longer than that of the cases doing other two procedures, that was 27. 1 ± 2. 4,10. 7 ±2. 2,4. 7 ±2.2 (months) respectively for body and bottom cancer, and 8.5 ±2. 1,6. 7 ± 1.9,3.1 ± 1.1 (months) respectively for neck cancer. For cancer at the body and bottom RO was achieved by expanded radical resection in 16/18(88％ ) cases and by standard radical resection in 7/12(58％ ) cases, while for cancer at the neck it was in 6/16(38％ ) cases, and in 3/13 (23％)cases only.ConclusionsThe median survival time is longer and RO resection rate is higher in patients with the cancer at the body and bottom than these at the neck of the gallbladder.

Computerizing extracting information from Chinese medicine literature seems more convenient than hand searching, which could simplify searching process and improve the accuracy. However, many computerized auto-extracting methods are increasingly used, regular expression is so special that could be efficient for extracting useful information in research. This article focused on regular expression applying in extracting information from Chinese medicine literature. Two practical examples were reported in this article about regular expression to extract "case number (non-terminology)" and "efficacy rate (subgroups for related information identification)", which explored how to extract information in Chinese medicine literature by means of some special research method.

Yuxingcao injection was suspended by China State Food and Drug Administration in 2006 for its severe adverse reaction in clinical practice. Althoug there are many real factors resulted in Yuxingcao injection's adverse reaction, some confounding factors should not be ignored. This study searched different kinds of related literatures and found out irregularity in defining dosage, disuses courses, indications and administration approach, which were the potential factors that caused the reported adverse drug reaction for Yuxingcao injection. And 97.8% adverse drug reaction in Yuxingcao injection happened 30 minutes after patients received administion, hence, observing patients'reaction in the first 30 minutes should be very important to prevent severe adverse drug reaction.

Objective To investigate the risk factors of lower extremity deep venous thrombosis(DVT)after internal fixation in patients with type C pelvic fracture,and to establish a relevent nomogram model.Methods Atotal of 217 patients with type C pelvic fractures who were admitted to the Orthopedic Center of the hospital from January 2018 to January 2022 were included in the study.All patients underwent internal fixation.According to whether DVT of the lower extremities was formed after operation,they were divided into the DVT group and the non-DVT group(N-DVT).The general clinical data and preoperative in-flammatory factor expression levels of the two groups was compared.Multivariate analysis was used to obtain independent predictors of DVT formation after internal fixation in patients with type C pelvic fractures.The correlation between preoperative inflammatory factors and DVT formation after internal fixation in patients with type C pelvic fractures was analyzed.The relevant nomograph model was constructed,and the Bootstrap method and calibration curve were used to verify the nomograph model internally.The ROC curve and deci-sion curve for predicting DVT formation after internal fixation in patients with type C pelvic fracture were drawn,and the predictive efficiency and net rate of return of independent prediction and combined prediction were an-alyzed.Results Multivariate analysis showed that age,diabetes,preoperative tumor necrosis factor-α(TNF-α),traction and braking,and bed rest time were independent predictors of DVT formation after internal fixa-tion in patients with type C pelvic fractures(P＜0.05).A nomograph model was constructed based on inde-pendent predictors to predict the formation of DVT after internal fixation in patients with type C pelvic frac-ture,and the C index of the distinguishing evaluation index of the nomogram model was 0.834(95％CI:0.812-0.924),the results of goodness of fit(H-L)test showed that the predicted value of DVT formation probability after internal fixation in patients with type C pelvic fracture was in good agreement with the actual observed value(P＞0.05).ROC curve analysis and decision curve analysis showed that age,diabetes,TNF-α,traction and braking,bed rest time and combined prediction model had good predictive performance and net yield in predicting DVT formation after internal fixation in patients with type C pelvic fracture.Conclusion Age,diabetes,TNF-α,traction braking and bed rest time are independent predictors of DVT formation after internal fixation in pa-tients with type C pelvic fracture.The nomogram model based on the above independent predictors has a high value in predicting DVT formation after internal fixation in patients with type C pelvic fracture.

Objective:To investigate whether murine peroxidase reductase-5(mPRDX5)has anti-tumor activity in mice,so as to further confirm the anti-tumor activity and mechanism of recombinant peroxidase reductase-5.Methods:High purity mPRDX5 was obtained by heterologous expression and purification in vitro.Pancreatic cancer Pan02 cells were inoculated subcutaneously on the left axillary back of mice to establish a tumor bearing mouse model.Mice were randomly divided into PBS(solvent control)group,GEM(gemcitabine)50.0 mg/kg group and mPRDX5 10.0 mg/kg group,with 10 mice in each group,and the tumor related indexes were detected in mice.Results:Compared with PBS group,weight of tumor-bearing mice in GEM group was decreased obviously,while weight of mPRDX5 group was increased to a certain extent.Tumor growth was good in PBS group,according to tumor volume,com-pared with PBS group,tumor growth inhibition rates in D7 were 87.07%in GEM group and 52.82%in mPRDX5 10.0 mg/kg group,re-spectively;according to tumor weight,compared with PBS group,GEM group and mPRDX5 10.0 mg/kg group had tumor growth inhibi-tion rates of 95.39%and 48.33%in D7,respectively.Polarization state of macrophages in tumor tissues of mice in PBS group and mPRDX5 group was analyzed,and it was found that compared with PBS group,M1 macrophages expressing CD86 in tumor tissues of mice in mPRDX5 group were significantly increased,while M2 macrophages expressing CD206 were significantly decreased.Conclu-sion:mPRDX5 has significant anti-pancreatic cancer activity in mice,and the activity is exerted by promoting M1-type polarization of macrophages in the tumor microenvironment.

Objective:To evaluate the clinical effect of Salviae Miltiorrhizae and Ligustrazine Hydrochloride injection on coronary heart disease in real world.Methods:Took the patients data with coronary heart disease of 24 tertiary-class A hospitals’ information system from October 2006 to December 2015 as the research targets. The patients injected by Salviae Miltiorrhizae and Ligustrazine Hydrochloride injection were selected as the observation group, and who were not injected were selected as the control group with ratio of 1:1, the same number on gender, similar age (+5 years difference) and similar condition upon hospitalization. Taking medication efficacy as the outcome evaluation index, the 30 confounding factors in this study were controlled by propensity scores, including hospital admission, co-morbidity, co-medication, occupation, cost category, and total hospitalization costs. Comparative analysis of the effect of Salviae Miltiorrhizae and Ligustrazine Hydrochloride injection on the clinical outcome of coronary heart disease by classical logistic regression and logistic regression weighted by propensity score.Results:30 confounding factors were identified and balanced, and 7 confounding factors were most affected factors that included clopidogrel bisulfate tablets, occupation, inosine tablets, levocarnidine injection, cerebroprotein hydrolysate injection, nitroglycerin and insulin. Both methods of logistic regression demonstrated that patients receiving parenterally administered Salviae Miltiorrhizae and Ligustrazine Hydrochloride injection had improved outcomes compared to those who did not receive the drug ( P<0.05). Conclusions:The study suggestes that the Salviae Miltiorrhizae and Ligustrazine Hydrochloride injection is a potential advantageous therapy in the treatment of coronary heart disease. However, a large amount of unknown confounding variable should be taken into account. Consider this research is a retrospective study, and the results need to be further verified by prospective studies.
