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.

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.

OBJECTIVESTo summarize the results of liver transplantation for various end-stage liver diseases at the Sun Yat-Sen University of Medical Sciences (SUMS), define the role of liver transplantation in the treatment of hepatocellular carcinoma and fulminant hepatitis B, and assess the efficiency of lamivudine on preventing HBV recurrence.

METHODSSeventy liver transplants performed at the SUMS between April 1993 and December 2000 were retrospectively analyzed. The main indications for liver transplant were hepatocellular carcinoma (26 cases), liver cirrhosis (21 cases), fulminant hepatitis B (12 cases), sclerosing cholangitis (4 cases) and other terminal liver diseases (7 cases). Lamivudine was used in twelve patients suffering from fulminant hepatitis B. Logistic multivariate regression analysis was applied to determine the risk factors predicting liver transplantation outcomes.

RESULTSFifty-four patients survived for more than one month, and 16 patients died within 30 days after orthotopic liver transplantation (OLT). The overall hospital survival rate was 77.1%. The hospital survival rates in the Child's A and B patients were 87.5% and 83.3%, respectively. Those rates were superior to those of the Child's C patients (P < 0.05). The outcome of patients with small hepatocellular carcinoma (HCC) was superior to that of patients with large HCC. Preoperative APACE III scores, the severity of ascites and serum creatine level had independent influence on outcome. Of the patients with fulminant HBV infection, 9 recipients survived for a follow-up period of 2 - 24 months. Treatment with lamivudine monotherapy was both well tolerated and efficacious in patients with fulminant hepatitis B.

CONCLUSIONSThe results indicate that orthotopic liver transplantation could provide long-term cure and palliation for patients with HCC, and that patient selection is extremely important in predicting outcome. The results support the continued application of liver transplantation as a therapeutic modality for various end-stage liver diseases and that lamivudine is an effective and safe monotherapy in OLT for patients with HBV infection.

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.
