Objective:To analyze the risk factors that affect the prognosis of patients with hypopharyngeal squamous cell carcinoma（HPSCC） and to compare the efficacy of surgical resection followed by adjuvant radiotherapy（SR） with that of neoadjuvant therapy consisting of platinum-based chemotherapy and fluorouracil combined with either cetuximab or nimotuzumab, followed by SR. The study also aimed to evaluate the overall survival（OS） of patients, their postoperative eating function, tracheostomy decannulation rate, and tumor response to the two neoadjuvant chemotherapies. Methods:A retrospective analysis was performed on the medical records of HPSCC patients who received SR or neoadjuvant therapy followed by SR treatment at the Shanghai General Hospital from 2012 to 2019 and had not undergone any prior treatment. The prognostic factors were analyzed, and the survival analysis of patients who underwent SR treatment with two neoadjuvant chemotherapy regimens was performed. Results:A total of 108 patients were included in the study. The results of the univariate analysis showed that gender（P=0.850） had no significant correlation with the survival rate of HPSCC patients who underwent SR. However, age, smoking history, alcohol consumption history, platelet-to-lymphocyte ratio（PLR）, neutrophil-to-lymphocyte ratio（NLR）, T stage, N stage, neoadjuvant therapy with either cetuximab or nimotuzumab combined with platinum-based chemotherapy and fluorouracil, and histological grade were significantly associated with prognosis（P<0.05）. The multivariate analysis revealed that smoking history, histological grade, and neoadjuvant therapy with either cetuximab or nimotuzumab combined with platinum-based chemotherapy and fluorouracil were independent risk factors affecting the prognosis of HPSCC（P<0.05）. Patients who received neoadjuvant therapy had longer OS than those who underwent SR only（P<0.001）. There was no significant difference in tumor response to the two neoadjuvant therapies and in OS（P>0.05）, and there was no significant difference in the rate of oral feeding and tracheostomy decannulation among the three treatment groups（P>0.05）. Conclusion:Univariate analysis showed that age at tumor onset, smoking history, alcohol consumption history, NLR, PLR, T stage, N stage, whether receiving neoadjuvant chemotherapy, and pathological grade were associated with the prognosis of HPSCC patients receiving SR treatment. Multivariate analysis showed that smoking history, pathological grade, and neoadjuvant chemotherapy were independent risk factors affecting the prognosis. Neoadjuvant chemotherapy with cetuximab or nimotuzumab can prolong the OS of patients, providing a certain basis and reference for the treatment of HPSCC.

Objective: To summarize the clinical characteristics of epileptic seizure associated with neurofibromatosis type 1 (NF1). Methods: From January 2017 to July 2023 at Children's Hospital Capital Institute of Pediatrics, medical records of patients with both NF1 and epileptic seizure were reviewed in this case series study. The clinical characteristics, treatment and prognosis were analyzed retrospectively. Results: A total of 15 patients(12 boys and 3 girls) were collected. Café-au-lait macules were observed in all 15 patients. There were 6 patients with neurodevelopmental disorders and the main manifestations were intellectual disability or developmental delay. The age at the first epileptic seizure was 2.5 (1.2, 5.5) years. There were various seizure types, including generalized tonic-clonic seizures in 8 patients, focal motor seizures in 6 patients, epileptic spasm in 4 patients, tonic seizures in 1 patient, absence in 1 patient, generalized myoclonic seizure in 1 patient and focal to bilateral tonic-clonic seizure in 1 patient. Among 14 patients whose brain magnetic resonance imaging results were available, there were abnormal signals in corpus callosum, basal ganglia, thalamus or cerebellum in 6 patients, dilated ventricles of different degrees in 3 patients, blurred gray and white matter boundary in 2 patients, agenesis of corpus callosum in 1 patient and no obvious abnormalities in the other patients. Among 13 epilepsy patients, 8 were seizure-free with 1 or 2 antiseizure medications(ASM), 1 with drug resistant epilepsy was seizure-free after left temporal lobectomy, and the other 4 patients who have received 2 to 9 ASM had persistent seizures. One patient with complex febrile convulsion achieved seizure freedom after oral administration of diazepam on demand. One patient had only 1 unprovoked epileptic seizure and did not have another seizure without taking any ASM. Conclusions: The first epileptic seizure in NF1 patients usually occurs in infancy and early childhood, with the main seizure type of generalized tonic-clonic seizure and focal motor seizure. Some patients have intellectual disability or developmental delay. Most epilepsy patients achieve seizure freedom with ASM.

OBJECTIVES: To study the clinical efficacy of ultrasound-guided endoscopic retrograde appendicitis therapy in children with appendix-related chronic abdominal pain. METHODS: A retrospective analysis was performed on the medical data of 30 children with the chief complaint of chronic abdominal pain who were admitted from August 2019 to May 2021. All the children were found to have inflammation of the appendix or intracavitary stool and fecalith by ultrasound and underwent ultrasound-guided endoscopic retrograde appendicitis therapy. The medical data for analysis included clinical manifestations, endoscopic findings, white blood cell count, neutrophil percentage, length of hospital stay, and cure rate. RESULTS: Among the 30 children with chronic abdominal pain, there were 13 boys (43%) and 17 girls (57%), with a mean age of (9±3) years (range 3-15 years) at diagnosis. The median duration of the disease was 12 months, and the median length of hospital stay was 3 days. The children had a median white blood cell count of 6.7×10⁹/L and a neutrophil percentage of 50%±13%. Fecalith and a large amount of feces were flushed out of the appendix cavity for 21 children (70%) during surgery. The follow-up rate was 97% (29/30), and the median follow-up time was 11 months (range 5-26 months). Of the 29 children, abdominal pain completely disappeared in 27 children (93%). CONCLUSIONS Ultrasound-guided endoscopic retrograde appendicitis therapy is effective in children with chronic abdominal pain caused by feces or fecalith in the appendix cavity.

Objective: To investigate the relationship between body mass index (BMI) and sexual development in Chinese children. Methods: A nationwide multicenter and population-based large cross-sectional study was conducted in 13 provinces, autonomous regions and municipalities of China from January 2017 to December 2018. Data on sex, age, height, weight were collected, BMI was calculated and sexual characteristics were analyzed. The subjects were divided into four groups based on age, including ages 3-<6 years, 6-<10 years, 10-<15 years and 15-<18 years. Multiple Logistic regression models were used for evaluating the associations of BMI with sexual development in children. Dichotomous Logistic regression was used to compare the differences in the distribution of early and non-early puberty among normal weight, overweight and obese groups. Curves were drawn to analyze the relationship between the percentage of early puberty and BMI distribution in girls and boys at different Tanner stages. Results: A total of 208 179 healthy children (96 471 girls and 111 708 boys) were enrolled in this study. The OR values of B2, B3 and B4+ in overweight girls were 1.72 (95%CI: 1.56-1.89), 3.19 (95%CI: 2.86-3.57), 7.14 (95%CI: 6.33-8.05) and in obese girls were 2.05 (95%CI: 1.88-2.24), 4.98 (95%CI: 4.49-5.53), 11.21 (95%CI: 9.98-12.59), respectively; while the OR values of G2, G3, G4+ in overweight boys were 1.27 (95%CI: 1.17-1.38), 1.52 (95%CI: 1.36-1.70), 1.88 (95%CI: 1.66-2.14) and in obese boys were 1.27 (95%CI: 1.17-1.37), 1.59 (95%CI: 1.43-1.78), and 1.93 (95%CI: 1.70-2.18) (compared with normal weight Tanner 1 group,all P<0.01). Analysis in different age groups found that OR values of obese girls at B2 stage and boys at G2 stage were 2.02 (95%CI: 1.06-3.86) and 2.32 (95%CI:1.05-5.12) in preschool children aged 3-<6 years, respectively (both P<0.05). And in the age group of 6-10 years, overweight girls had a 5.45-fold risk and obese girls had a 12.54-fold risk of B3 stage compared to girls with normal BMI. Compared with normal weight children, the risk of early puberty was 2.67 times higher in overweight girls, 3.63 times higher in obese girls, and 1.22 times higher in overweight boys, 1.35 times higher in obese boys (all P<0.01). Among the children at each Tanner stages, the percentage of early puberty increased with the increase of BMI, from 5.7% (80/1 397), 16.1% (48/299), 13.8% (27/195) to 25.7% (198/769), 65.1% (209/321), 65.4% (157/240) in girls aged 8-<9, 10-<11 and 11-<12 years, and 6.6% (34/513), 18.7% (51/273), 21.6% (57/264) to 13.3% (96/722), 46.4% (140/302), 47.5% (105/221) in boys aged 9-<10, 12-<13 and 13-<14 years, respectively. Conclusions: BMI is positively correlated with sexual development in both Chinese boys and girls, and the correlation is stronger in girls. Obesity is a risk factor for precocious puberty in preschool children aged 3-<6 years, and 6-<10 years of age is a high risk period for early development in obese girls.

OBJECTIVE: To explore the molecular genetic characteristics of children with B-cell acute lymphoblastic leukemia (B-ALL) and the application value of RNA-sequencing (RNA-seq). METHODS: The clinical and laboratory examination data of newly diagnosed B-ALL children who were given treatment in the Department of Hematology, Children's Hospital of Chongqing Medical University from May 2015 to April 2020 were collected and analyzed. All children were confirmed by bone marrow morphology, histochemical staining and flow cytometry, and the karyotype analysis, FISH, RT-PCR and RNA-seq detection were conducted. RESULTS: There were 71 males and 58 females with a median age of 50(8-190) months in 129 newly diagnosed children with B-ALL. The fusion gene was positive in 99 children (76.7%). A total of 86 leukemia related or possibly related gene mutations were detected, with a positive rate of 66.7%. There was no significant difference in the detection rates of ETV6-RUNX1, BCR-ABL1, TCF3-PBX1 and KMT2A rearrangements among FISH, RT-PCR and RNA-seq. Rare fusion genes were detected by RNA-seq, including 1 case of KMT2A-USP2, 4 cases of Ph-like related fusion genes, 5 cases of MEF2D rearrangement, 5 cases of PAX5 rearrangement, 3 cases of ZNF384 rearrangement, as well as several fusion genes whose significance were not clear or had not been reported in children with leukemia. Besides, children with ETV6-RUNX1 fusion gene had good response to induction of remission, while children with BCR-ABL1 and ZNF384 rearrangement had poor response, the remission rate of minimal residual disease was statistically significant compared with other types (P<0.05). CONCLUSION RNA-seq can not only detect known fusion genes, but also discover new or rare fusion genes and gene mutations. The application of RNA-seq has important guiding significance for risk classification and precise targeted therapy of pediatric B-ALL.

Objective:This research aims to construct the "disease-gene-target-components-drug" network with the methods of network pharmacology and bioinformatics， and to explore the key genes and signaling pathways of Xiao Qinglongtang in the treatment of bronchial asthma. Method:First，we selected the differentially expressed genes between patients with asthma and healthy people with use of the gene expressing Omnibus（GEO） database，and searched the active ingredients from Xiao Qinglongtang with use of TCMSP database，and then screened disease genes and herb ingredient targets as intersecting genes to construct the protein-protein interactions （PPI） network by using R language and Cytoscape 3.7.2 software. At the same time Gene Ontology （GO） analysis and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analysis were carried out. Result:Series GSE43696 in GEO database were successfully filtered，which contained 108 pieces of chip data. A total of 820 differentially expressed genes were screened from the chip data. Then we filtered 169 active ingredients and 246 targets of Xiao Qinglongtang from database. Through the above steps，we obtained 25 intersecting genes， and PPI network results showed that 91 potential targets may be involved in the mechanism of Xiao Qinglongtang. A total of 180 gene functions such as response to oxidative stress，inflammatory response，extracellular matrix organization and positive regulation of vascular endothelial growth factor production were showed in GO enrichment analysis results. 39 signaling pathways were showns in the results of KEGG pathway enrichment analysis，such as T helper cell 17（Th17） cell differentiation，interleukin 17（IL-17）signaling pathway，tumor necrosis factor（TNF） signaling pathway，and hypoxia inducible factor-1（HIF-1） signaling pathway. Conclusion:Xiao Qinglongtang fully embodies the characteristics of multi-components，multi-targets and multi-pathways in the intervention of bronchial asthma. The results of the study could provide an important basis for mechanism research of Xiao Qinglongtang in treating asthma.

OBJECTIVETo discuss the characteristics of Chinese medicine (CM) syndrome factors and distribution of congestive heart failure (CHF), and provide a basis for the diagnosis criteria of essential syndromes.

METHODSBased on databases of China National Knowledge Infrastructure (CNKI, 1980-2012) and Chinese Journal of Chongqing VIP Database (1989-2012), the eligible studies in CHF and extracted factors associated with compound syndromes were analyzed. All the syndromes were classified into deficiency, excess, and deficiency-excess in complexity syndrome were classified. Compound syndromes were separated into syndrome factors including single, double, three or four factors, along with the frequency of occurrence. The relation of CHF syndromes with age, gender, primary disease, brain natriuretic peptide (BNP) and cardiac functional grade was studied in 1,451 CHF cases (between December 2010 and September 2012), and the clinical distribution of common CHF syndromes was summarized.

RESULTSThe literature study involved 6,799 CHF cases in 66 literatures after screening. Of the different factors affecting CHF, qi deficiency was the most important one. In deficiency syndrome, Xin (Heart)-qi-deficiency was the most common single factor, and deficiency of both qi and yin was the most common double factor. The retrospective analysis involved 1,451 CHF cases (431 cases with test results of BNP). The xin blood stasis and obstruction and deficiency of both qi and yin syndrome were mostly seen in female patients, and phlegm-blocking-Xin-vessel and qi-deficiency-blood-stasis syndrome mostly in males. Xin-qi-deficiency and qi-deficiency-blood-stasis syndrome were mostly seen in patients aged 50-60 years. Patients aged over 60 years likely manifest deficiency of both qi and yin and Xin blood stasis and obstruction syndrome. The severity of syndrome is aggravated with increased BNP and cardiac functional grade.

CONCLUSIONSThe essential syndromes of CHF include qi-deficiency-blood-stasis and deficiency of both qi and yin. The clinical distribution is linked to patients' age and gender. BNP and cardiac functional grade is closely related to CHF syndromes, which may indicate the severity of CM syndromes of CHF.

OBJECTIVETo evaluate the clinical performance of glass fiber reinforced resin-bonded fixed partial denture(GFR-RBFPD) as a periodontal splint on abutment teeth with reduced periodontal support.

METHODSThirty fixed-fixed GFR-RBFPD were delivered to restore anterior partial edentulous dentitions. The adjacent abutment teeth had severely reduced periodontal support and were not indicated for full crown retained FPD. The success rate and functional survival rate had been recorded and the periodontal condition had been evaluated for 4 years. The results were statistically analyzed with single factor variance analysis and chi square test(α=0.05).

RESULTSIn the first, second, and third year following restoration, one connector fractured in each year and they were repaired with adhesive resin and the pontics were kept in place for function. In the third and fourth years after restoration, there was one pontic displacement with fracture of connectors. The total survive rate was 83%(25/30) and the functional survival rate was 93% (28/30) at the end of the fourth year. The main reason of failure was fracture of connector. About 22%(13/60) of the adjacent teeth showed marginal bone height decrease, while the other 78% (47/60) increased with statistic significant difference from one year after the restoration to the end of the observation term(P<0.05). The periodontal condition of the adjacent teeth was improved after the restoration.

CONCLUSIONSThe four years clinical evaluation indicates that the GFR-RBFPD may be used as fixed prostheses to replace lost one to three anterior teeth with reduced periodontal support of abutment teeth.

ObjectiveTo investigate the pathological characteristics, diagnosis, and differential diagnosis of embryonal rhabdomyosarcoma (ERMS) in the male reproductive system.

METHODSWe obtained the clinicopathological features, immunophenotypes, and electron microscopic findings of 11 male patients with ERMS in the reproductive system from 2000 to 2015, analyzed the data, and reviewed relevant literature.

RESULTSERMS developed in these patients at a median age of 17 (9－58) years, 3 cases in the testis, 4 in the scrotum, 1 in the epididymis, and 3 in the prostate. ERMS presented no clinical specificity, which made it difficult to be differentiated from inflammatory and other benign lesions. Microscopically, the tumor cells were arranged in a diffuse or fascicular distribution and mainly composed of short spindle-like, round, or irregularly shaped cells with nuclear hyperchromatism, the cytoplasm strongly eosinophilic, with differentiation of the striated muscle. Some of the cells were naively differentiated or tennis racket-shaped and some exhibited vacuolar degeneration in the cytoplasm. The nuclei were round or short spindle-shaped with visible nucleoli and mitoses. Immunohistochemically, the tumor cells were positive for Myogenin (5/6), Desmin (11/11), MyoD1 (8/9), and Myosin (1/2). Electron microscopy revealed early myofibrils in the cytoplasm of the tumor cells.

CONCLUSIONSERMS is a rare and highly malignant tumor characterized by local invasion and early metastasis and apt to develop in the reproductive system of young males. The diagnosis of the malignancy is mainly based on its histopathological and immunohistochemical manifestations, combined with electron microscopy when necessary. Early surgical resection in combination with radio- and chemotherapy is recommended for its treatment, which could reduce the recurrence of the tumor and improve the survival of the patients.
