Objective: Para-aortic lymph node dissection (PALND) is a widely used treatment that causes many complications. This study is to evaluate the efficacy and safety of nerve-sparing para-aortic lymph node dissection (NSPALND) by comparing it with conventional PALND in gynecological malignancies and to prove whether locating the superior hypogastric plexus (SHP) can help reveal the para-aortic nerves. Methods: This is a retrospective study of the patients who underwent para-aortic lymphadenectomy from January 2020 to December 2022 at Zhejiang Cancer Hospital. All of them were divided into NSPALND and PALND groups according to whether or not nervesparing was performed. The surgical, functional and oncological outcomes were evaluated. Results: There were 43 patients enrolled, of which, 20 patients underwent NSPALND and 23 patients underwent PALND. The para-aortic nerves were successfully revealed by locating the SHP in all 20 cases of NSPALND. The post-operative anal exhaust time in the NSPALND group was significantly shorter than that in the PALND group (2.5 vs. 4 days, p=0.006), and the incidence of acute intestinal obstruction in the NSPALND group was significantly lower than that in the PALND group (10% vs. 39%, p=0.029). There was no difference between the two groups in terms of catheterization duration, urinary retention, dysuria, as well as the number of lymph nodes removed and the para-aortic recurrence rate. Conclusion NSPALND can significantly reduce the rate of acute intestinal obstruction and improve post-operative intestinal function. Locating the SHP and using it as an anatomical landmark to reveal the para-aortic nerves is feasible. Its exact clinical value needs to be further studied.

ObjectiveTo understand the usage of antibiotics in outpatients in a county of Zhejiang Province from 2015 to 2020， so as to provide a basis for further standardizing the clinical application of antibiotics in this region. MethodsOutpatient records and prescription records of 146 public medical institutions from 2015 to 2020 were extracted from the electronic medical record data sharing platform system of medical institutions in a county of Zhejiang Province. The utilization rates and the number of types of antibiotics used in outpatient patients were described. According to the drug anatomy， therapeutic and chemical classification system （ATC）， clinical application classification and dosage form， the use status of different types of antibiotics was observed. The annual percentage change （APC） was used to analyze the time trend of antibiotic use. Among the antibiotic prescriptions in each year， the proportions of prescriptions aimed for different use reasons and patients were compared to analyze the changes in the structures of antibiotic prescriptions. ResultsDuring 2015‒2020， a total of 2 861 438 prescriptions were issued in146 primary public medical institutions in this county， including 314 642 prescriptions for antibiotics， and the overall utilization rate of antibiotics was 11%. The utilization rate of antibiotics showed a decreased trend across the years （from 14.23% in 2015 to 7.59% in 2020，APC=-11.51%， 95%CI=-0.01%‒-21.7%， t=-12.05， P<0.001） and an obvious seasonal variation character （higher in winter and spring， lower in summer and autumn）. Cefoxitin sodium for injection was the most used antibiotic in 2015， and cefuroxime was the most used antibiotic from 2015 to 2020， respectively. The utilization rates of cephalosporins （APC=-11.06%， 95%CI=0‒-20.89%， t=-22.233， P<0.001）， quinolones （APC=-9.74%， 95%CI=0‒-18.53%， t=-7.652， P=0.002）， macrolides （APC=-17.52%， 95%CI=0‒-17.52%， t=-3.626， P=0.022） and lincoamides （APC=-49.01%， 95%CI=0‒-74%， t=-3.35， P=0.029） showed a decreasing trend across the years. There were differences in the distribution of drug use reasons （χ²=9 458.427， P<0.001）， as well as the age （χ²=5 421.709， P<0.001） and sex （χ²=245.322， P<0.001） of patients. During the observation period， 50.69% of antibiotic prescriptions were used to treat respiratory diseases， with the highest proportion of 57.67% in 2015 and the lowest proportion of 34.93% in 2020. 58.37% of patients were aged 50‒70 years， with a decreasing proportion of patients under 50 years （17.83% in 2015， 6.64% in 2020） and an increasing proportion of patients over 70 years （24.1% in 2015， 38.41% in 2020）. ConclusionThe utilization rate of antibiotics used in outpatients from primary public medical institutions in a county of Zhejiang Province shows a decreasing trend across the years， but higher than that of secondary and above hospitals in China， and also higher than that of primary medical institutions in economically-developed areas. The management and monitoring of the clinical use of antibiotics in the county should be actively strengthened.

Gastroesophageal reflux related cough is located in the lung and stomach.The basic pathogenesis is the inversion of stomach qi and the lung loss propagating and descending.In view of the above,based on the theory of"relevance of lung and stomach",this article analyzed the modern mechanism of"relevance of lung and stomach"in gastroesophageal reflux related cough,which included"microinhalation"theory,"esophagus-bronchial reflex"theory,and"airway neurogenic inflammation"theory.This article also put forward the TCM disease name of"gastric cough",and the treatment methods of"simultaneous treatment of lung and stomach"and"treatment of cough from stomach",which would provide new ideas for the theoretical and mechanism research of TCM treatment of gastroesophageal reflux related cough.

Objective:To summarize the clinical-imaging features and prognoses of acute encephalopathy combined with biphasic seizures and late reduced diffusion (AESD).Methods:A retrospective analysis was performed. The clinical and imaging data and follow-up results of 8 children with AESD, admitted to Departments of Neurology and Rehabilitation Medicine, Wuhan Children's Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from January 2020 to April 2022 were collected.Results:The antecedent infections in 8 children were predominantly gastrointestinal and respiratory tract infections and convulsive seizures occured within 24 h of fever. The clinical presentation was biphasic: 3 had sustained convulsive state in the first phase of the disease, and all showed cluster seizures with worsening impairment of consciousness in the second phase of the disease, including 4 with involuntary movements during recovery from the disease. Seven children required admission to Intensive Care Unit, 4 required tracheal intubation for assisted ventilation, and 1 was combined with septic shock. Brain MRI findings of 8 children were "bright tree" in the second phase of the disease, including bilateral symmetrical and bilateral asymmetrical involvements, with diffuse and focal involvements. All 8 children were treated with glucocorticoids and/or gammaglobulin, and 2 were given mild hypothermia brain protection. Follow-up was performed for more than 3 months, and brain MRI indicated cerebral atrophy, subdural effusion and cerebral malacia. All the 8 children survived with different degrees of sequelae. Two children had Extended Glasgow Outcome Scale scores of 4, 4 had scores of 5, and 2 had scores of 7.Conclusion:AESD is a special clinical-maging syndrome, characterized by biphasic seizure and "bright tree" on head MRI; the survival is high, but neurological sequelae of different degrees are easily left behind.

Enterotoxigenic Escherichia coli（ETEC）infection can induce watery diarrhea，leading to dehydration，electrolyte disturbance，and even death in severe cases. Recombinant B subunit/inactivated whole-cell cholera（rBS/WC）vaccine is effective in preventing ETEC infectious diarrhea. On the basis of the latest evidence on etiology and epidemiology of ETEC，as well as the effectiveness，safety，and health economics of rBS/WC vaccine，National Clinical Research Center for Child Health（The Children’s Hospital，Zhejiang University School of Medicine）and Zhejiang Provincial Center for Disease Control and Prevention invited experts to develop expert consensus on rBS/WC vaccine in prevention of ETEC infectious diarrhea. It aims to provide the clinicians and vaccination professionals with guidelines on using rBS/WC vaccine to reduce the incidence of ETEC infectious diarrhea.
