Objective To analyze the etiological characteristics and the variation of pathogens spectrum in hospitalized children with a-cute respiratory tract infection(ARTI)before and after COVID-19 under"the level B of management for class B"of infectious diseases(Level B for Class B)in Shenzhen,in order to provide reference for the clinical diagnosis,treatment and prevention of ARTI.Meth-ods The ARTI cases from January 8,2022 to July 30,2022 were selected as before"Level B for Class B",and the cases from Janu-ary 8,2023 to July 30,2023 were selected as after"Level B for Class B".The pharyngeal swab samples submitted for analyzing 11 common pathogens,such as COVID-19,influenza virus(Ⅳ),respiratory syncytial virus(RSV)and mycoplasma pneumoniae(MP)in the children with ARTI admitted to Shenzhen Children's Hospital.Results SARS-CoV-2 were detected as positive in 347 cases,a-mong which 225 cases were before"Level B for Class B"including 29 cases combined with other pathogens(12.89％,29/225)and human parainfluenza viruses(HPIV)was the most common(31.03％,9/29).After"Level B for Class B",SARS-CoV-2 were detec-ted as positive in 122 cases,including 28 cases combined with other pathogens(22.95％,28/122),and RSV was the most common(28.57％,8/28).There was a statistical difference between the positive rate of SARS-CoV-2 combined with other pathogens before and after"Level B for Class B"(X2=5.834,P=0.016).After"Level B for Class B",the total pathogen detection rate(positive for at least one pathogen)was 60.82％(2 864/4 709)in the spring(January 8,2023 to April 30,2023),and influenza virus A(IVA)(22.64％,1 066/4 709),rhinovirus(HRV)(19.86％,935/4 709)and RSV(13.29％,626/4 709)were the main pathogens,and there were 301 cases(6.39％,301/4 709)of mixed infections.In the summer(May 1,2023 to July 30,2023),the total detection rate of pathogens was 70.26％(4 012/5 710),among which RSV(21.63％,1 235/5 710),MP(13.91％,794/5 710),HPIV(10.05％,574/5 710)were the main pathogens,and there were 710 cases(12.43％,710/5 710)of mixed infections,all of which were significantly higher than the same period before"Level B for Class B".The difference was statistically significant(P＜0.05).Conclusion After"Level B for Class B"for COVID-19,the detection rate of 11 common pathogens increased significantly and the pathogen spectrum of ARTI changed significantly.

Objective:To explore a multimodal perioperative analgesia plan for patients undergoing microvascular decompression surgery for trigeminal neuralgia.Methods:Eighty patients who underwent microvascular decompression surgery for trigeminal neuralgia admitted to the Xiangya Hospital, Central South University from April 2017 to April 2019 were randomly divided into a nerve block group (group A) and a control group (group C) using a random number table method, with 40 patients in each group. The group A underwent surgical block of the lateral occipital and auricular nerves under ultrasound guidance before induction, with 3 ml of 0.5% ropivacaine used at each site. The group C did not undergo nerve block. Both groups received intravenous injections of midazolam, sufentanil, cisatracurium, etomidate, and lidocaine for anesthesia induction, followed by tracheal intubation and maintenance of anesthesia with propofol and remifentanil. After surgery, an analgesic pump was connected. The total amount of intraoperative use of sufentanil and remifentanil in both groups was recorded, as well as the pain Visual Analogue Scale (VAS) and postoperative anesthesia related complications at 2, 6, 24, and 48 hours after surgery.Resultsl:The total amount of sufentanil and remifentanil used during surgery in the group A was less than that in the group C (all P<0.05). The incidence of postoperative nausea and vomiting in the group A patients was lower than that in the group C ( P<0.05), and the nausea and vomiting score was also lower than that in the group C ( P<0.05). There was no statistically significant difference in the incidence of other postoperative complications (all P>0.05). There was a statistically significant difference in VAS scores between the two groups at 6 hours after surgery ( P<0.05). Conclusions:Occipital and auricular nerve blockade can reduce the amount of opioid drugs used during microvascular decompression surgery in patients with trigeminal neuralgia, thereby reducing the incidence of nausea and vomiting. The postoperative analgesic effect is good.

Objective:To evaluate the clinical efficacy of endoscopy for early cancer of duodenal papilla.Methods:A retrospective analysis was performed on data collected from 23 consecutive patients with early cancer of duodenal papilla, who underwent endoscopic treatment from January 2015 to January 2021 in Beijing Friendship Hospital. Baseline data, endoscopic and pathological data, occurrence and outcome of complications were studied.Results:Twenty-three patients successfully received endoscopic treatment. The maximal diameter of lesions evaluated under endoscopy was 1.90±0.83 cm. Among the 23 cases, 20 underwent endoscopic mucosal resection and 3 underwent endoscopic piecemeal mucosal resection. Delayed bleeding occurred in 5 cases (21.7%), 3 patients (13.0%) developed postoperative hyperamylasemia, 6 patients (26.1%) developed mild acute pancreatitis, and 1 patient (4.3%) had pancreatic duct stent displacement after the operation, which improved after medical or endoscopic treatment. No perforation occurred during the perioperative period. In terms of final pathology, the en bloc resection rate was 82.6% (19/23), and the complete resection rate was 78.3% (18/23). Preoperative endoscopic ultrasonography showed that 19 lesions were confined to the mucosal layer, which were all demonstrated by postoperative pathology. Four other cases were suspected to be involved in the submucosa or the end of the pancreaticobiliary duct under endoscopic ultrasonography, two of which were confined to the mucosal layer, and the other 2 cases involved the submucosal layer, so additional surgery was performed. A total of 18 patients were followed up, among whom 14 achieved complete resection of postoperative pathology, and 2 patients (14.3%, 2/14) were found to have recurrence at 12 and 51 months respectively after the treatment and did not relapse after surgical treatment and endoscopic treatment respectively. Among 4 other patients of follow-up whose pathology did not achieve complete resection, 1 had no recurrence, and the other 3 received additional surgical treatment without recurrence.Conclusion:Endoscopic treatment for early cancer of duodenal papilla is safe and effective. It is necessary to improve preoperative evaluation, stay alert to perioperative complications, and pay attention to regular postoperative endoscopic follow-up.

Objective:To evaluate the clinical efficacy of endoscopic treatment for early nonampullary duodenal cancer.Methods:Data of patients with early nonampullary duodenal cancer, who underwent endoscopic treatment from January 2015 to January 2021 at Beijing Friendship Hospital were retrospectively analyzed. Baseline data, endoscopic treatment methods, wound closure, pathology, the occurrence and outcome of complications of patients were studied.Results:A total of 47 patients who successfully went through endoscopic treatment were enrolled. Seventeen cases received endoscopic mucosal resection (EMR), 5 cases received endoscopic submucosal dissection (ESD), and 7 cases received ESD+EMR (hybrid ESD). Six cases were converted to hybrid ESD due to difficulty in ESD. Four cases received full-thickness resection with over-the-scope clip system (OTSC), and 8 cases received endoscopic piecemeal mucosal resection (EPMR). Among the 47 cases of early cancer, the en bloc resection rate was 83.0% (39/47), and the complete resection rate was 85.1% (40/47). Four patients (8.5%) had perforation which occurred at the duodenal descending part during the perioperative period, among whom, 2 patients (4.3%) recovered after endoscopic treatment, 2 others (4.3%) recovered after surgical intervention. There were no complications such as postoperative bleeding or infection during the perioperative period.Conclusion:Endoscopic treatment for early nonampullary duodenal cancer is safe and effective. A specific treatment plan can be selected according to the location, size and specific conditions of the lesion. For the operation of the descending part, it is necessary to be more vigilant to against the occurrence of perforation complications.

The aim of this study was to investigate the preventive effect of pancreatic duct stent on acute pancreatitis after endoscopic retrograde cholangiopancreatography. A retrospective analysis of the case data of patients who first underwent endoscopic retrograde cholangiopancreatography for choledocholithiasis in the Beijing Friendship Hospital from January 2015 to December 2019 for 5 years. According to whether the pancreatic duct stent was indwelled during the operation, they were divided into pancreatic duct stent group (147 cases) and non-indwelling pancreatic duct stent group (192 cases). The incidence of acute pancreatitis after endoscopic retrograde cholangiopancreatography was compared between the two groups according to COTTON criteria. Independent sample t test, Pearson Chi-square test (χ 2) and Fisher′s exact test were used to compare groups′ differences. There were 2 cases of acute pancreatitis in the pancreatic duct stent group, all of which improved after 48 hours. There were 22 cases of acute pancreatitis in the non-indwelling pancreatic duct stent group, of which 20 cases improved within 48 hours, and the other 2 cases had severe pancreatitis, which improved and discharged after 30 days of treatment. There was significant difference in the incidence of acute pancreatitis between the pancreatic duct stenting group (1.4%) and the group without placement of pancreatic duct stents (11.5%) (χ2=12.905, P<0.001). In conclusion, Pancreatic duct stent may be an effective method to prevent PEP.

Objective:To analyze the effect of mechanical assisted sputum drainage combined with early grade 4 rehabilitation exercise on Intensive Care Unit-acquired weakness (ICU-AW) .Methods:The convenient sampling method was used to select 98 patients who were hospitalized in ICU of Xinyang Central Hospital and underwent mechanical ventilation from June 2020 to June 2021. They were randomly divided into observation group and control group, with 49 cases in each group. During the ICU stay, the control group received ICU routine nursing, and the observation group received mechanical-assisted sputum expectoration combined with early stage 4 rehabilitation exercise on the basis of the control group. The incidence of ICU-AW, duration of mechanical ventilation, length of ICU stay, diaphragm thickness and diaphragmatic thickening fraction were compared between the two groups.Results:The occurrence time of ICU-AW in the observation group was later than that in the control group, the incidence of ICU-AW in the observation group was lower than that in the control group and mechanical ventilation time and length of ICU stay in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.05) . After intervention, skeletal muscle mass, diaphragm thickness and diaphragm thickening fraction in the observation group were all higher than those in the control group, and the differences were statistically significant ( P<0.05) . The skeletal muscle mass, diaphragm thickness and diaphragm thickening fraction of the control group after the intervention were lower than those before the intervention, and the differences were statistically significant ( P<0.05) . There was no statistically significant difference in limb skeletal muscle mass, diaphragm thickness and diaphragm thickening fraction in the observation group after intervention compared with those before intervention ( P>0.05) . Conclusions:Mechanical assisted sputum drainage combined with early grade 4 rehabilitation exercise can effectively prevent the occurrence of ICU-AW in ICU patients undergoing mechanical ventilation, shorten the duration of mechanical ventilation and ICU stay, maintain limb skeletal muscle mass and diaphragm function, which benefits patients.

Objective To study the therapeutic value of endoscopy for primary duodenal lesions. Methods Data of 79 consecutive patients with primary duodenal lesions, who underwent endoscopic treatment from January 2015 to January 2018 at Beijing Friendship Hospital, were retrospectively analyzed. Patients were divided into the complication group and the non-complication group, and further grouped according to lesion locations and endoscopic categories. Baseline data of patients, endoscopic treatment, wound closure method, pathological results, the occurrence and outcome of complications were studied. Results A total of 79 patients successfully went through endoscopic treatment, including 59 cases of endoscopic mucosal resection ( EMR) , 5 cases of endoscopic submucosal dissection ( ESD) , 6 cases of full-thickness resection with OTSC metal clips, and 9 cases of endoscopic piecemeal mucosal resection ( EPMR) . In all 79 cases, complications occurred in 8 patients ( 10. 1％) during the perioperative period, all at the duodenal descending segment and duodenal papilla. In all 47 cases whose lesions located at duodenal papilla and duodenal descending segment, the complication incidence was 17. 0％ ( 8/47) , significantly higher than that of non-descending and papilla part [ 0 ( 0/32 ) , P=0. 012 ] . Two ( 2. 5％) cases had complications requiring further intervention with endoscopy or surgery. Among 8 patients with complications, 1 patient ( 2. 1％) developed intraoperative perforation, 1 patient ( 2. 1％) developed delayed bleeding, 6 patients ( 12. 8％) developed mild acute pancreatitis, and these 8 patients recovered after treatment. These 47 patients were further divided into the duodenoscopy group and the gastroscopy group according to endoscopic categories, the complications incidence in the duodenoscopy group ( 28. 0％, 7/25) was also significantly higher than that in the gastroscopy group [ 4. 5％( 1/22) , P=0. 037] . Conclusion Endoscopic treatment is safe and effective for primary duodenal lesions. But for the operations in the duodenal descending segment and the duodenal papilla, as well as in the case of duodenoscopy, it is necessary to be more vigilant about the occurrence of complications.

Objective To analyze the clinical features of patients with sporadic adult-onset neuronal intranuclear inclusion disease (NIID),and raise awareness of the disease among medical workers.Methods The clinical data of two patients with pathologically confirmed adult sporadic NIID,admitted to our hospital in February 2018 and October 2018,were collected.The clinical manifestations,head MR imaging,cutaneous pathological features,treatments and prognoses were retrospectively analyzed.Results Both patients were characterized with slow progressive dementia,accompanied with diverse clinical manifestations involving the central and autonomic nervous systems.Acute encephalopathic signs occurred in both patients.Head MR imaging showed extensive leukoencephalopathy mainly in the frontal and parietal lobes;these white matter abnormalities showed hyperintensity in T2-weighted imaging and liquid attenuated inversion recovery sequences,and equal or low signal in T1-weighted imaging.Remarkably,specific curve-like high-intensity signals along the corticomedullary junction in the bilateral frontal lobe were both observed in diffusion-weighted imaging.Patient 2 with seizures showed unilateral cerebral cortical edema on head MR imaging.In both patients,skin biopsy revealed specific eosinophilic inclusion bodies in the nucleus of some sweat gland cells,adipocytes and fibroblasts.Patient one was treated with dexamethasone intravenous drip to relieve headache and vision loss,and cognitive therapy was given.The acute encephalopathy of patient two was relieved by intravenous gamma globulin.Conclusions NIID has various clinical manifestations of central,peripheral,and autonomic nerve systems.Head MR imaging characteristic changes and skin pathological biopsy contribute to the diagnosis.Immunomodulatory therapy may be effective for acute encephalopathic symptoms in NIID.

Objective To explore the improvement of cognitive impairment in patients with mild and moderate vascular cognitive impairment( VCI) treated with cerebralcare granule ( CG) and basic treat-ment.Methods From October in 2014 to December in 2016 year,143 cases of VCI patients were admitted from six hospitals in some areas of Hebei Province as the research objects,and divided into CG treatment group (experimental group,n=98) and conventional treatment group (control group,n=66).Three months and six months after treatment,the score of mental state examination ( MMSE) ,the Montreal cognitive assess-ment scale ( MoCA) and the daily living capacity scale( ADL) of the two groups were compared after 3 and 6 moths of treatment.Results ①The total score of MMSE in the experimental group was higher than that of the control group for six months after treatment, and the difference was statistically significant ( ( 23. 76 ± 4.02) vs (21.52±5.13),P<0.05).②Six months after treatment,the total score of MoCA ((21.06±4.66) vs (18.32±5.20)) and visual spatial/executive function((3.05±1.37) vs (2.42±1.66)),calculation force ((2.24±0.84) vs (1.83±1.05)) and orientation ability((5.20±1.12) vs (4.06±1.35)) scores in the ex-perimental group were significantly higher than those in the control group (P<0.05) .③Six months after treat-ment,the ADL score in the experimental group was lower than that before treatment,and the difference was statistically significant((24.96±8.74) vs (29.20±11.55),P<0.05);while there was no significant difference in the ADL score between the experimental group and the control group after 6 months (P>0.05).Conclusion CG can improve cognitive function in mild to moderate VCI patients,mainly in visual space/execution func-tion,calculation ability and orientation ability,and with the extension of treatment time,the curative effect is more obvious.
