ObjectiveTo explore the possible mechanism of Bimin Formula （鼻敏方） in treating lung-spleen qi deficiency syndrome of allergic rhinitis （AR） with high mucin secretion. MethodsThirty-four SD rats were randomly divided into a blank group （8 rats）， a model group （8 rats）， a low-dose Bimin Formula group （8 rats）， and a high-dose Bimin Formula group （10 rats）. Except for the blank group， the other groups were subjected to AR lung-spleen qi deficiency rat models induced by smoking， gavage of Ginkgo biloba leaf extract， and ovalbumin. After modeling， rats in the low- and high-dose Bimin Formula groups were given Bimin Formula concentrate （concentration of 2.16 g/ml） by gavage at doses of 1.08 g/100 g and 2.16 g/100 g， respectively， while rats in the model group were given 0.5 ml/100 g of normal saline by gavage， once daily for 28 days； the blank group was not intervened. Behavioral assessments were performed after intervention. ELISA was used to detect the levels of peripheral blood total immunoglobulin E （IgE）. HE staining was used to observe the pathological changes of nasal mucosa epithelium in rats， while immunohistochemistry was used to detect the expression of transmembrane protein 16A （TMEM16A） and mucin 5AC （MUC5AC） protein in nasal mucosa. Western Blot was used to detect the expression of nuclear factor kappa B （NF-κB） protein， and RT-PCR was used to detect the expression of TMEM16A， MUC5AC， and NF-κB mRNA in nasal mucosa. ResultsHE staining showed that the nasal mucosa epithelial cell structure in the blank group was intact without shedding， swelling， or necrosis； the nasal mucosa epithelial tissue of rats in the model group was thickened and partially shed， with infiltration of eosinophils and lymphocytes visible； the pathological changes in nasal mucosa tissue of rats in the high- and low-dose Bimin Formulagroups were improved， and more improvement was showen in the high-dose group. Compared with those in the blank group， the behavioral scores and peripheral blood total IgE levels of rats in the model group significantly increased， as well as the expression of TMEM16A， MUC5AC， and NF-κB proteins and mRNA in nasal mucosa （P＜0.05 or P＜0.01）. Compared with those in the model group， the behavioral scores and peripheral blood total IgE levels of rats in the high-dose Bimin Formula group decreased， and the expression of TMEM16A， MUC5AC， and NF-κB proteins and mRNA in nasal mucosaalso decreased （P＜0.05 or P＜0.01）； the behavioral scores and peripheral blood total IgE levels of rats in the low-dose Bimin Formula group were reduced， and the expression of TMEM16A and MUC5AC proteins and mRNA in nasal mucosa， as well as the expression of NF-κB protein decreased （P＜0.05 or P＜0.01）， but the difference in NF-κB mRNA expression was not statistically significant （P＞0.05）. Compared with the low-dose Bimin Formula group， the expression of NF-κB protein in the high-dose group decreased （P＜0.01）. ConclusionBimin Formula may improve the symptoms and high mucus secretion of AR lung-spleen qi deficiency by regulating the TMEM16A/NF-κB/MUC5AC signaling pathway in nasalmucosa.

The search period was from January 1, 2014, to June 20, 2023. Two researchers independently evaluated the quality of the literature and extracted relevant data.Results:A total of 23 articles were included, comprising three guidelines, two systematic reviews, six expert consensus statements, seven randomized controlled trials, one quasi-experimental study, and four cohort studies. The evidence was categorized into six themes: multidisciplinary team collaboration, health education, facilitation measures, pre-activity assessment, activity content, and safety assurance, resulting in 25 evidence-based recommendations.Conclusions:This study summarizes 25 best evidence-based recommendations for early ambulation in patients undergoing open lumbar surgery. Healthcare providers are advised to apply these recommendations in clinical practice while considering the specific clinical context and individual patient differences. Multidisciplinary collaboration is essential to develop personalized early ambulation plans.

Objective:To investigate the knowledge and practice of the Sixth Chinese national consensus report on the management of Helicobacter pylori ( H. pylori) infection (treament excluded) (referred to as sixth national consensus)and 2022 Chinese national clinical practice guideline on H. pylori eradication treatment (referred to as guideline) among gastroenterologists in China, so as to provide out relevant training in the future. Methods:A questionnaire was designed according to sixth national consensus and guideline, including knowledge and practice of sixth national consensus and guideline, and the detection, indications of eradication, the relationship between infection and gastrointestinal microbiota, and eradication of H. pylori. From November 1 to 30 in 2023, the questionnaire-based survey was conducted among 1 506 gastroenterologists from secondary and tertiary hospitals of 24 provinces, autonomous regions and municipalities in China with convenience sampling method using the "Questionnaire Star" online questionnaire platform and the questionnaire link was sent by WeChat. Descriptive methods were used for statistical analysis. Results:A total of 1 442 valid questionnaires were collected. The awareness rate of sixth national consensus and guideline of gastroenterologists was 83.7% (1 207/1 442), and 47.2% (680/1 442) had read the relevant content in detail. Urea breath test (97.4%, 1 404/1 442) was the most commonly used method for diagnosing current H. pylori infection, however, more than half of the physicians chose serological test (53.3%, 769/1 442) for the diagnosis of current infection. The common indications of H. pylori eradication could be identified by 84.3%(1 215/1 442) of gastroenterologists. The most well-known eradication regimen was bismuth quadruple regimen (98.5%, 1 421/1 442), while some physicians still believed that the standard triple regimen (31.8%, 459/1 442) and sequential regimen (21.9%, 316/1 442) were recommended by the guideline. A further 20.2% (291/1 442) frequently prescribed a triple regimen combined with gastric mucosal protectants and the awareness rate of high-dose dual regimen was 59.1% (852/1 442). Amoxicillin + clarithromycin (65.4%, 943/1 442) and amoxicillin+ furazolidone (20.1%, 290/1 442) were commonly used antibiotic combinations in bismuth quadruple therapy. Potassium-competitive acid blockers and double-dose proton pump inhibitors were commonly used in bismuth quadruple therapy by 45.4% (655/1 442) and 46.0% (664/1 442) of physicians, respectively. For patients with multiple failed eradications, furazolidone was the most commonly used antibiotic for re-eradication(71.7%, 1 034/1 442). Conclusion:The knowledge and practice of gastroenterologists on H. pylori infection in China deviates from the new consensus and guideline, and more publicity and training should be carried out in future to improve the ability of gastroenterologists to standardise the diagnosis and treatment of H. pylori infection.

Objective:To investigate the clinical features of pertussis in children and analyze the risk factors of severe pertussis.Methods:The clinical data of 248 children with pertussis hospitalized in Hunan Children′s Hospital from March 2018 to March 2022 were analyzed retrospectively.According to the age at admission, the patients were divided into two groups: ≤3 months and > 3 months.According to the patient′s condition, they were classified into ordinary group and severe group.According to the pathogens detected, the children were divided into single infection group and mixed infection group.The independent sample t-test, chi- square test were used to analyze the clinical indexes of the infants in above groups. Results:(1)Of 248 hospitalized children with pertussis, 204 cases (82.2%) were less than 1 year old, 92 cases (37.0%) had contact with a coughing family member before, and 169 cases (68.1%) were unvaccinated.Among 248 children, 193 cases (77.8%) had an elevated white blood cell count, and 145 cases (58.4%) had mixed infections.The most common pathogen was respiratory syncytial virus [29/248(11.6%)]. About 173 cases (69.7%) had concurrent pneumonia, and 35 cases (14.1%) had pulmonary consolidation.(2)Compared with the group > 3 months of age, more patients in the group ≤3 months of age had contact with a coughing family member before, and suffered from cyanosis, dyspnea, respiratory failure, heart failure and pertussis encephalopathy ( χ2=4.612, 20.810, 7.882, 16.617, 13.740, 7.846, all P<0.05). The proportions of patients in the group ≤3 months of age required intensive care unit(ICU) hospitalization and mechanical ventilation were higher than those in the group > 3 months of age ( χ2=14.810, 21.436, all P<0.05). The mortality of the group ≤3 months of age was higher than that of the group >3 months of age ( χ2=12.016, P<0.05). Children ≤3 months of age had a higher WBC level [(27.83±27.70)×10 9/L vs.(23.34±15.28)×10 9/L, t=22.244, P<0.001], longer duration of spasmodic cough [(16.56±9.33) d vs.(15.06±6.16) d, t=10.145, P=0.002] and longer hospitalization time [(11.47±10.48) d vs.(9.48±4.80) d, t=20.050, P<0.001] than those >3 months of age.(3)Compared with the ordinary group, a higher proportion of children in the severe pertussis group were under 3 months old, and had not been vaccinated against pertussis vaccine ( χ2=14.803, 4.475, all P<0.05). The ratio of patients with dyspnea, an lymphocyte count/neutral cell(LC/NC) ratio <1, mixed infections, lung consolidation and pleural effusion in the severe pertussis group was higher than that in the ordinary group ( χ2=116.940, 43.625, 13.253, 106.370, 11.874, all P<0.05). The patients in the severe pertussis group had a higher WBC [(61.66±29.63)×10 9/L vs.(18.83±10.00)×10 9/L, t=112.580, P<0.001] and a lower LC (0.494±0.186 vs.0.676±0.132, t=13.752, P<0.001) than those in the ordinary group.(4)Compared with the single infection group, the proportions of children with fever, dyspnea, fine moist lung rales, an LC/NC ratio <1, and lung consolidation were higher in the mixed infection group ( χ2=8.909, 6.804, 7.563, 8.420, 12.458, all P<0.05). More children in the mixed infection group required ICU hospitalization and mechanical ventilation than those in the single infection group ( χ2=11.677, 7.397, all P<0.05). The mixed infection group had higher respiratory failure and death rates than the single infection group ( χ2=7.980, 4.267, all P<0.05). Compared with the single infection group, the mixed infection group had a higher WBC level [(27.73±24.13)×10 9/L vs.(21.25±14.65)×10 9/L, t=13.318, P<0.001], longer hospitalization time [(11.593±9.010) d vs.(8.339±4.047) d, t=17.283, P<0.001], and a smaller LC ratio (0.626±0.165 vs.0.684±0.132, t=7.997, P=0.005). (5) Logistic regression analysis showed that age ≤3 months, peak WBC and dyspnea were risk factors of severe pertussis. Conclusions:Hospitalized pertussis children are prone to pneumonia and pulmonary consolidation.Patients aged ≤3 months with a large WBC and dyspnea easily develop into severe pertussis.Monitoring blood routine is helpful for judging the severity of the disease.Mixed infections increase the incidence of complications and can impair the treatment effect.

Microglia (MG) are resident immune cells in the central nervous system (CNS) and the first defense line of CNS damage. The maintenance of MG function requires abundant energy, and lipid can serve as an energy source for the brain when glucose utilization is limited, and lipid can also function as signaling molecule. Alzheimer's disease (AD) is the most common neurodegenerative disease, and MG lipid metabolism plays an important role in the development of this disease. Drugs targeting lipid metabolism provide a new direction for AD treatment. This review starts with the specific mechanism of lipid metabolism in MG, and briefly introduces the effect of lipid metabolism on MG function and its role in AD.

The most common metastatic site of prostate cancer is the bone, followed by the lung, bladder, liver, and adrenal gland. We report on a rare case of pancreatic metastasis from prostate cancer. A 52-year-old patient was admitted to the hospital with epigastric pain for 20 days. PET-CT showed malignant lesions in the prostate and pancreas, and prostate and pancreas puncture biopsies were performed, respectively. The patient was diagnosed as prostate cancer with pancreatic metastasis according to the pathological findings. After undergoing androgen deprivation therapy and docetaxel chemotherapy for 6 cycles, reexamination revealed that the pancreatic metastases had disappeared.

Objective:To evaluate the application effect of a series of optimized nursing measures under the concept of enhanced recovery after surgery (ERAS) on the perioperative period of patients with posterior cervical single-door spinal canal augmentation and angioplasty.Methods:A retrospective cohort study design was used. From April to December 2018, using cluster sampling method, 476 patients admitted to a class third hospital for posterior cervical single-door spinal canal augmentation and angioplasty were selected as research objects. According to whether or not to implement ERAS optimization, the patients were divided into ERAS group with 100 cases and control group with 376 cases. The control group underwent routine measures such as preoperative evaluation and education, blood management, anesthesia points, surgical points, incision closure, pain management, drainage tube management, and prevention of complications. On the basis of routine measures, the ERAS group implemented optimized measures for ERAS on clinical measures such as fasting water and infusion management before surgery, postoperative diet and infusion management, bowel preparation, urinary tube management, and out of bed activities. A self-designed questionnaire was used to investigate the two groups of patients. The general information, implementation of ERAS nursing (preoperative fasting time, the preoperative water cut-off time, the time for anesthesia, the time for surgery, the amount of infusion before surgery, the amount of infusion during surgery, the amount of infusion after surgery, use of indwelling urinary catheters) , recent effect evaluation indicators [length of hospitalization, cost of hospitalization, discharge daily living ability score (Barthel index) , postoperative complications, postoperative urinary retention]and long-term effect evaluation indicators [Japan Orthopedic Association (JOA) score, Neck Disability Index (NDI) score, neck and shoulder pain VAS score, neck and shoulder stiffness and numbness VAS score, 90-day readmission rate]of the two groups were compared.Results:A total of 295 cases were included in the study, including 69 cases in the ERAS group and 226 cases in the control group. The study found that there were statistically significant differences between the two groups of patients in terms of preoperative fasting time, the preoperative water cut-off time, the amount of infusion before surgery, the amount of infusion after surgery and the use of indwelling urinary catheters ( P<0.05) . The comparison of recent effects showed that the difference in length of hospitalization and Barthel index between the two groups were statistically significant ( P<0.05) , while there was no significant difference in the incidence of postoperative complications of the two groups ( P>0.05) . The comparison of long-term effects showed that there was no significant difference in the modified JOA score, NDI score, neck and shoulder discomfort and the 90-day readmission rate in the two groups ( P>0.05) . Conclusions:The application of ERAS nursing in the perioperative period of patients with posterior cervical single-door spinal canal augmentation and angioplasty can effectively reduce patients' fasting time and water cut-off time, use of urinary catheters, which can reduce patients' hospitalization time, but has no significant effect on the long-term effect of surgery.

Objective: To evaluate the safety and feasibility of treating de novo coronary lesions with paclitaxel-eluting balloon. Methods: This is a retrospective study, which enrolled 76 patients with 80 de novo coronary lesions treated with paclitaxel-eluting balloons(<30% residual stenosis and there was no blood flow limited dissection after pretreatment) from April 2015 to November 2016 in Guangdong general hospital. The data of basic characteristics,procedures,devices and follow-up information were retrieved and analyzed. The primary endpoint was the composite of cardiac death, recurrent myocardial infarction and target lesion revascularization. Results: (1)The age was (63.3±10.3) years. There were 68.4%(52/76) acute coronary syndrome patients, prevalence of type 2 diabetes was 36.8%(28/76), and 64.5%(49/76)patients with at least one high bleeding risk. (2)The lesion length was (17.4±7.6)mm, and the stenosis was (88.1±8.2)%.The reference vessel diameter≥2.75 mm accounted for 51.2% (41/80), and bifurcation stenosis accounted for 67.5%(54/80). (3)53.7%(43/80) lesions were pretreated with scoring balloon to optimize plaque modification. The paclitaxel-eluting balloon length and diameter were (22.3±5.5)mm and (2.74±0.52)mm.The residual stenosis was (12.3±10.3)%. Procedural success was 88.8%(71/80).Bail-out stenting rate was 5.0%(4/80). (4)The median follow-up duration was 12(6, 25) months. Primary endpoint occurred in 3 cases (3.9%), including 2 cardiac deaths(1 patient died of recurrent myocardial infarction, and 1 patient died of acute heart failure induced by severe mitral insufficiency), and one patient receivedtarget lesion revascularization. Conclusion In case of no more than 30% residual stenosis and no blood flow limited dissection after lesion pretreatment,it is safe and feasible to treat de novo coronary lesionsusing paclitaxel-eluting balloon.

Objective To explore the feasibility of single port laparoscopy in classification and treatment of Meckel's diverticulum in children and its guiding treatment.Methods The clinical data in 75 children cases of Meckel's diverticulum with symptoms treated in our hospital from Aug.2011 to Aug.2015 were retrospectively analyzed.Meckel's diverticulum was classified under single port laparoscopy.The operation modes were selected according to different classifications.The excised materials were submitted to the pathologic examination.Results Among 75 children cases,50 cases were the simple type of Meckel's diverticulum and 25 cases were complex type of Meckel's diverticulum.The average operative time in the simple type and complex type was (38.93±8.75) min and(55.64 ± 13.27) min respectively,average bleeding amounts were (46.58 ± 15.81) mL and (50.12 [16.90) mL respectively,average postoperative hospitalization time was (7.33±1.41)d and (7.52 ± 1.68)d respectively,the operative time in the simple type was less than that in the complex type(P＜0.05),the other two indexes had no statistical difference between the two groups(P＞0.05).The ectopic gastric mucosal pathological change was only seen in the simple type,while the inflammatory manifestation in the complex type had higher proportion.The main clinical manifestations were lower gestational tract bleeding and infection.The two groups all obtained follow up.One case of simple type appeared the symptoms of abdominal pain and hematochezia and was cured after the second operation.Conclusion Meckel's diverticulum can be divided into the simple type and complex type under single port laparoscopy.The operation mode can be selected according to different types.This method is safe and reliable and is worthy of being clinically promoted.
