Background:The efficacy of standard triple therapy for eradication of Helicobacter pylori(Hp)is decreasing in recent years,and bismuth-containing quadruple regimen becomes the first-line therapy for Hp infection. However,the application of bismuth has some limitations. Aims:To investigate the efficacy of proton pump inhibitor(PPI)-based standard triple therapy combined with teprenone for Hp eradication. Methods:A total of 155 Hp-infected chronic gastritis patients were enrolled from Jan. 2013 to Dec. 2014 at Aerospace Center Hospital,and were randomly assigned into standard triple therapy group,bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group. Patients in standard triple therapy group were given rabeprazole sodium 20 mg + amoxicillin and clavulanate potassium 914 mg +clarithromycin 500 mg bid for 10 days. Patients in bismuth-containing quadruple therapy group were given standard triple therapy combined with bismuth potassium citrate 0. 6 g bid for 10 days. Patients in teprenone-containing quadruple therapy group were given standard triple therapy combined with teprenone 50 mg bid for 10 days. Symptoms of patients were evaluated before and after eradication therapy. Four weeks after the end of therapy,13 C-urea breath test( UBT)was reexamined to assess the status of Hp infection. Results:One hundred and fifty-two patients completed the treatment course. By ITT analysis,the eradication rates of standard triple therapy group,bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were 69. 8%(37 / 53),86. 5% (45 / 52)and 88. 0% (44 / 50), respectively;by PP analysis,the eradication rates of the three groups were 71. 2%(37 / 52),88. 2% (45 / 51)and 89. 8%(44 / 49),respectively. Eradication rates analyzed by ITT and PP in bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were significantly higher than those in standard triple therapy group(P <0. 05),but no statistically significant difference was found between these two groups( P > 0. 05). Relieving rates of abdominal pain,abdominal distention and belching in bismuth-containing quadruple therapy group and teprenone-containing quadruple therapy group were higher than those in standard triple therapy group,but statistically significant difference was only found in relieving of abdominal pain between teprenone-containing quadruple therapy group and standard triple therapy group(88. 9% vs. 70. 3% ,P < 0. 05). Adverse effects included transient and mild nausea,diarrhea and black stool, etc. Conclusions:Teprenone-containing quadruple regimen are effective for Hp eradication and symptoms relieving with no severe adverse effects,the efficacy is comparable with bismuth-containing quadruple regimen.

Objective:To clarify the effects of microwave radiation on anxiety-like behavior, the histomorphology of the secondary visual cortex, and calcium activity in neurons.Methods:36 C57BL/6N mice were selected and divided into control group and microwave radiation group according to the random number table method. In the simple behavioral testing, there were 8 mice in the control group and 7 mice in the radiation group. Combining fiber optic recording with behavioral experiments, there were 8 mice in the control group and 7 mice in the radiation group. Hematoxylin-eosin (HE) staining was conducted with 3 mice in each group. A high-power microwave simulated source in the X-band with a center frequency of 9.875 GHz and an average power density of 12 mW/cm 2 was used to irradiate the mice for 15 minutes, establishing a microwave radiation animal model. Then, anxiety-like behavior changes in the radiation group were identified using the open-field and elevated plus maze (EPM) tests. The effects of microwave radiation on the histomorphology of the secondary visual cortex were investigated using HE staining and optical microscopy. Based on the genetically encoded calcium imaging technique, as well as optical fiber recording combined with behavioral paradigms in the open field and the EPM, the changes of calcium activity in neurons in the V2M region of the secondary visual cortex were detected. Results:Compared to the control group, the radiation group showed a significant decrease in the frequency of exploring the central region of the open field and the open arm of the EPM ( t = 2.24, 3.10, P < 0.05). Furthermore, the radiation group exhibited the degeneration and apoptosis of some neurons in the secondary visual cortex, primarily manifested as pyknosis and deep staining, cell body shrinkage, and the slightly widening of perivascular space. Fiber optic recordings and behavioral experiments indicated that compared to the control group, mice in the radiation group exhibited significantly increased calcium activities in neurons of the secondary visual cortex when exploring the central region of the open field ( t = -2.75, P < 0.05) or the open arm of the EPM ( t = -2.77, -3.41, P < 0.05) compared to those before radiation after microwave exposure. Conclusions:Microwave radiation can induce anxiety-like behaviors and histopathological changes in the secondary visual cortex. Increased calcium activity in neurons of the secondary visual cortex is proved to be an important mechanism underlying the changes in anxiety-like behavior due to microwave radiation.

Rapid and accurate identification and effective non-drug intervention are the worldwide challenges in the field of depression. Electroencephalogram (EEG) signals contain rich quantitative markers of depression, but whole-brain EEG signals acquisition process is too complicated to be applied on a large-scale population. Based on the wearable frontal lobe EEG monitoring device developed by the authors' laboratory, this study discussed the application of wearable EEG signal in depression recognition and intervention. The technical principle of wearable EEG signals monitoring device and the commonly used wearable EEG devices were introduced. Key technologies for wearable EEG signals-based depression recognition and the existing technical limitations were reviewed and discussed. Finally, a closed-loop brain-computer music interface system for personalized depression intervention was proposed, and the technical challenges were further discussed. This review paper may contribute to the transformation of relevant theories and technologies from basic research to application, and further advance the process of depression screening and personalized intervention.

【Objective】 To compare the perioperative blood loss between interlaminar and transforaminal approaches by percutaneous endoscopic discectomy in order to provide more reference for guiding the proper choice of surgical methods clinically. 【Methods】 We retrospectively analyzed the clinical data of 160 patients who underwent percutaneous endoscopic lumbar discectomy from June 2019 to November 2020, with 80 patients in interlaminar approach group and 80 in transforaminal approach group. The blood loss was calculated according to Gross formula. 【Results】 The perioperative total blood loss (mL), hidden blood loss (mL) and hemoglobin loss (g/L) were significantly lower in interlaminar approach group than in transforaminal approach group (119.73±179.26 vs. 158.6±190.65, 109.73±179.53 vs. 148.78±190.19, 3.76±8.12 vs. 4.31±7.62) (P<0.05). However, there was no significant difference in visible blood loss between the two groups. 【Conclusion】 The perioperative hidden blood loss accounts for a large proportion in percutaneous endoscopic lumbar discectomy. In addition, the interlaminar approach causes less blood loss than the transforaminal approach.

Bacillus cereus belongs to Gram-positive bacteria, which is widely distributed in nature and shows certain pathogenicity. Different B. cereus strains carry different subsets of virulence factors, which directly determine the difference in their pathogenicity. It is therefore important to study the distribution of virulence factors and the biological activity of specific toxins for precise prevention and control of B. cereus infection. In this study, the hemolysin BL triayl was expressed, purified, and characterized. The results showed that the bovine pathogenic B. cereus hemolysin BL could be expressed and purified in the prokaryotic expression system, and the bovine pathogenic B. cereus hemolysin BL showed hemolysis, cytotoxicity, good immunogenicity and certain immune protection in mice. In this study, the recombinant expression of hemolysin BL triayl was achieved, and the biological activity of hemolysin BL of bovine pathogenic ceroid spore was investigated. This study may facilitate further investigating the pathogenic mechanism of B. cereus hemolysin BL and developing a detection method for bovine pathogenic B. cereus disease.
