Objective To investigate the curative effect of ribavirin atomization inhalation on the young children's pneumonia.Methods 224 young children with pneumonia were randomly divided into treatment groups and control group,besides treated with the ordinary therapeutical methods,the treatment group were given ribavirin atomization inhalation 10mg/(kg · d),bid,continued for 7 days,and the control group were given ordinary therapeutical method.Results The treatment group' s curative rate was 91.07％,and the control group' s effective rate was 82.14％,compared with the control group,there was significantly statistical difference(x2 =5.64,P ＜ 0.05).Conclusion Ribavirin atomization inhalation treatment on young child with pneumonia had a higher curative rate and low incidence of adverse reactions,and it was worthy of being widely applied in clinical practice.

As the development of robotic surgery in urology, the simulation training platform is playing an important role in the training of urologists on robotic surgery training.Currently, the available training simulators for urological robotic surgery are composed of virtual simulators such as VR and AR, and physical (mechanical) simulators such as dry-lab and wet-lab.The reality and validity of various simulation training platforms have been validated in different degree by many researches, which demonstrated the useful and helpful effect on the training and improving of robotic surgery skills.However, we need further study to develop more useful and precise training modules, to integrate advantages of different simulators, and to establish more reasonable learning curve.

Objective:To evaluate the diagnosis and treatment of abdominal cocoon.Methods:The clinical data of 8 patients with abdominal cocoon in our hospital from Jan 2015 to Dec 2021 were retrospectively reviewed including clinical and imaging manifestations, treatment and follow-up.Results:One case was asymptomatic, and the other 7 cases suffered from recurrent abdominal pain with complete or incomplete intestinal obstruction. The median course of disease was 6 months (15 days to 40 years). Six cases underwent laparcoscopic cocoon membrane resection and intestinal adhesion lysis, of which 2 cases underwent laparotomy, one case was converted to open surgery, 4 cases underwent concomitant appendectomy. Follow-up ranged from 3 to 69 months, there were 2 cases complicating early inflammatory intestinal obstruction, 1 case suffred wound fat liquefaction and infection, 1 case with a colic 5 months after operation, and the others were doing well.Conclusions:The clinical characteristics of abdominal cocoon disease are not typical. Surgery is the main treatment. The prognosis of the disease is generally fair.

Objective:To comprehensively analyze the expression profile of circular RNA (circRNA) and construct competing endogenous RNA (ceRNA) regulatory networks in tuberous sclerosis complex related renal angiomyolipoma (TSC-RAML).Methods:According to the diagnostic criteria of TSC determined by the international consensus group on tuberous sclerosis in 2012, tumor tissues and paired normal renal tissues of 3 patients with TSC-RAML who were diagnosed in our hospital from January 2017 to January 2019 were collected. The circRNA, miRNA and mRNA of 3 paired samples were detected by circRNA, miRNA chip technology and next generation sequencing respectively, and the differential molecules were determined. Gene Ontology(GO) functional enrichment analysis and Kyoto Encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed based on differential mRNA molecules and host genes of circRNA. Based on differential circRNA, miRNA and mRNA, up-regulated and down-regulated ceRNA regulatory networks were established.Results:A total of 330 up-regulated and 336 down-regulated differential circRNA, 8 up-regulated and 7 down-regulated miRNA, 800 up-regulated and 1130 down-regulated mRNA were screened. Through GO and KEGG enrichment analysis, many pathways including lipid metabolism, focal adhesion and mineral absorption were abnormally altered. Finally, the up-regualted ceRNA network led by hsa_circ_0092022, hsa_circ_0076859 and hsa_circ_0033388 and down-regulated network led by hsa_circ_0000374, hsa_circ_0000141, hsa_circ_0072665, hsa_circ_0009503 and hsa_circ_0000009 were constructed.Conclusions:There were many differentially expressed circRNA between TSC-RAML and paired normal renal tissues. ceRNA regulatory networks may be involved in the occurrence and development of TSC-RAML.

Objective:To explore the clinical value of 68Ga-pentixafor PET/CT targeting for CXCR4 in the diagnosis and prognosis evaluation of primary aldosteronism (PA). Methods:Retrospective analysis was performed on information of 72 patients diagnosed with PA who received operations according to the results of 68Ga-pentixafor PET/CT in our hospital. There were 37 males and 35 females, with the average age of (48.3±9.5) years old. The average lesion diameter was (1.60 ± 0.54)cm. The preoperative systolic and diastolic blood pressure were (177.3 ± 23.9)mmHg and (107.6 ± 13.2)mmHg, respectively. The average preoperative potassium level was (2.62 ± 0.56)mmol/L. The average aldosterone concentration was (17.98 ± 4.66)ng/dl, and the median plasma renin activity was 0.01 (0.01, 0.09) ng/(ml·h). All patients underwent 68Ga-pentixafor PET/CT examination, which lead to the decision of surgical strategies. For those patients with single lesion, multiple lesions in one side or positive lesion in one side but negative in the opposite side, surgical resection of the positive side lesion or total adrenalectomy was considered. For those patients with bilateral positive lesions, surgical resection of the side with more significant positive lesions or total adrenalectomy was considered. For those with negative multiple lesions, the surgical strategy was designed according to the results of CT examination or AVS. The positive rate of 68Ga-pentixafor PET/CT and its relationship with the clinical characteristics and prognosis of patients were analyzed. Results:The results of 68Ga-pentixafor PET/CT were positive in 62 of 72 patients diagnosed with PA (86.1%), and the median SUVmax value was 11.1 (7.1, 16.2). The SUVmax value was positively correlated with the maximum diameter of adrenal lesion ( r=0.468) and negatively correlated with blood potassium levels ( r=-0.437), while not significantly correlated with other clinical characteristics. The positive rate of adenoma by 68Ga-pentixafor PET/CT was higher than that of nodular hyperplasia [90.5%(57/63) vs. 55.6%(5/9), P=0.018], and the SUVmax value in adenoma was also higher than that in nodular hyperplasia [11.9(7.8, 16.2) vs. 4.3(3.4, 11.3), P=0.022]. 32 cases were cured after operations, and 37 cases were improved. And 3 cases were not cured. The SUVmax value of lesions in the cured patients was higher than that in the improved patients [15.4(8.1, 22.7) vs. 10.1(6.8, 13.3), P=0.013]. Among 59 cases of PA patients with single adrenal lesions, 50 cases represented positive results of 68Ga-pentixafor PET/CT. 23 cases in 50 positive cases were cured and 27 cases were improved after resection of positive lesions. In the 13 PA patients with multiple adrenal lesions who underwent surgery according to the results of 68Ga-pentixafor PET/CT, 12 patients (92.3%) showed postoperative prognosis in line with preoperative expectations. Conclusions:68Ga-pentixafor PET/CT showed high positive rate in the diagnosis of PA, especially for adenoma.The SUVmax value of the adrenal lesion was correlated with the blood potassium level, the size of the lesion and the postoperative prognosis. In addition, 68Ga-pentixafor PET/CT could effectively guide the surgical decision of PA.
