Objective To evaluate the efficacy of 10-day compound allantoin containing quadruple regimen in the treatment of chronic gastritis with Helicobacter pylori (H.pylori) infection,and to compare with the bismuth-containing quadruple therapy.Methods Altogether 173 patients with H.pylori positive chronic gastritis confirmed by gastric endoscope were divided into 10-day compound allantoin containing quadruple regimen group (n =43),24-day compound allantoin containing quadruple regimen group (n =46),10-day bismuth-containing quadruple regimen group (n =42) and 24-day bismuth-containing quadruple regimen group (n =42).After the treatment,the eradication rate of H.pylori,the rate of gastrointestinal symptoms (epigastric pain,bloating and belching) relief and the adverse effects of each group were observed.Intention-to-treat (ITT),per-protocol (PP) statistical analysis and chi-square analysis were performed for statistical analysis.Results H.pylori eradication rates of 10-day compound allantoin containing quadruple regimen group,24-day compound allantoin containing quadruple regimen group,10-day bismuth-containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group analyzed by ITT were 90.7％ (39/43),91.3％ (42/46),90.5％ (38/42) and 88.1％ (37/42),respectively; while analyzed by PP were 90.7％ (39/43),93.3％ (42/45),90.5％ (38/42) and 90.2％ (37/41),respectively.And there were no statistical differences between groups (all P＞0.05).Ten days after the treatment,the rates of epigastric pain relief of 24-day compound allantoin containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group were 81.1％ (30/37) and 78.8％ (26/33),respectively,the rates of bloating relief were 82.4％ (28/34) and 71.0％ (22/31),respectively,and the rates of belching relief were 76.9％ (20/26) and 75.0％ (21/28),respectively.There were no statistical differences between the two groups (all P＞ 0.05).However after 24-day treatment,the rates of epigastric pain relief of 24-day compound allantoin containing quadruple regimen group and 24-day bismuth-containing quadruple regimen group were 91.9 ％ (34/37) and 87.9％ (29/33),respectively,the rates of bloating relief were 94.1％ (32/34) and 87.1％ (27/31),respectively,and the rates of belching relief were 96.2％ (25/26) and 85.7％ (24/28),respectively.There were no statistical differences between the two groups (all P＞0.05).And the rates of epigastric pain and bloating relief increased after 24-day treatment compared with those of 10-day treatment,however the differences were not statistically significant between the two groups (all P＞ 0.05).In 24-day compound allantoin containing quadruple regimen group,the rate of belching relief was higher after 24-day treatment compared with that of 10-day treatment,and the difference was statistically significant (x2=4.127,P=0.042).No severe adverse effects were observed in each group,and there were no adverse effects such as oral metal odor,tongue black and melena in compound allantoin containing quadruple therapy.Conclusions Ten-day compound allantoin containing quadruple therapy as first-line approach in the treatment of chronic gastritis with H.pylori infection can get better H.pylori eradication and the efficacy is similar to bismuth quadruple therapy.Meanwhile the symptom relief rate is high and no obvious adverse effects were found.

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 explore the role of vinegar in ancient prescriptions,inherit and explore the unique value of vinegar in traditional Chinese medicine,and provide reference for modern clinic.[Methods]Based on the records of the efficacy of vinegar in traditional Chinese medicines and medical records from various dynasties,this paper classifies and sorts out the ancient literature on the vinegar in prescriptions.Combining the Qi and taste of vinegar,the theory of reinforcing and reducing about viscera,and the idea of visceral-Qi corresponding to nature rhythms,this paper explores the role of vinegar in prescriptions from five aspects:promoting Qi and blood circulation,promoting blood circulation and stopping bleeding,healing sores and relieving swelling,clearing heat and detoxicating,and calming endogenous wind and blooming the sprit.[Results]The sour taste of vinegar acting on the liver helps to regulate activities of Qi,tonifies the lungs to help regulate water passages,fragrance and warm of vinegar promote Qi,bitter and warm of vinegar eliminate dampness,thus eliminating the concretions and gatherings,and resolving phlegm-dampness.Vinegar fragrance acts on the spleen and sour acts on the liver,vinegar can achieve the effect of promoting blood circulation and stopping bleeding by regulating the liver and spleen.The main reason for its application in skin diseases is that vinegar tonifies the lungs with the sour taste,and lungs govern skin and hair,and vinegar has astringent properties.The sour taste of vinegar acting on the liver can help the liver detoxify,while the bitter taste can clear heat and detoxicate.Therefore,vinegar is often used in prescriptions such as detoxification of drugs,food and insects,etc.Sour acts on the liver to control conveyance and dispersion,while the fragrance of vinegar acts on the spleen to refresh the mind,so it is also used to treat symptoms such as stroke and fainting.[Conclusion]Vinegar tastes sour,bitter,fragrant and warm.It is the main reason why vinegar is used as a necessary medicine in promoting Qi and blood circulation,promoting blood circulation and stopping bleeding,healing sores and relieving swelling,clearing heat and detoxicating,and calming endogenous wind and blooming the spirit.According to the theory of reinforcing and discharging viscera,sour acts on the liver;According to the theory of visceral-Qi corresponding to nature rhythms,sour can regulate the heart,liver and lung.By combing the application of vinegar in ancient prescriptions systematically,it helps to provide literature support and theoretical reference for further improving the clinical application of vinegar in prescription.

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.
