OBJECTIVES: This study aims to explore the clinical and pathological characteristics of congenital granular cell tumors and provide some references for clinical diagnosis, differential diagnosis, and treatment. METHODS: Nine ca-ses of congenital granular cell tumors who visited the Children's Hospital of Zhejiang University School of Medicine from February 2008 to March 2022 were retrospectively analyzed. Herein, its clinical characteristics, pathological characteristics, treatment, and prognosis were summarized and analyzed. RESULTS: We found that nine patients were all female, aged 1‑38 days when they saw the doctor. Three of them were attached in maxillary and the other six were attached in mandible. Meanwhile, six tumors were found during the mother's pregnancy at 28-39 weeks and three tumors were found at the baby's birth. One case was excised surgically under local anesthesia, and the other cases were excised surgically under general anesthesia. After 1 month to 12 years of follow-up, patients have no recurrence, however, two cases emerged new teeth from the tumor resection site. Histopathology of all excised lesions was congenital granular cell lesion. CONCLUSIONS Congenital granular cell tumor is a benign tumor and the prognosis is good. Therefore, surgical resection of the tumor can be done without extensive resection, and it generally does not relapse. Thus, ultrasonography during pregnancy is an important method for the early detection of congenital granular cell epulis.

Dysglycemia is independently associated with the mortality of critically ill patients. Therefore, the management of blood glucose plays an important role in comprehensive therapy. It is suggested that the same target value of blood glucose (7.8-10.0 mmol/L) should not be set for all critically ill patients. Instead, it should be individually set based on the causes of the patient's admission and the status of blood glucose before admission. For this reason, there is an urgent need for a convenient protocol and method to regulate the dosage of insulin. The first hospital of Jiaxing, collaborating with information engineers, developed a modified eProtocol-insulin for domestic population with mathematical modeling and developed an Application Software (APP), which is convenient for clinical use. This is the first eProtocol-insulin and smart device APP for critically ill patients in China.

ObjectiveTo investigate the clinical characteristics and risk factors of hyperamylasemia and acute pancreatitis after percutaneous transhepatic biliary stenting (PTBS). MethodsA retrospective analysis was performed for the clinical data of 249 patients with malignant biliary obstruction who were admitted to Department of Interventional Radiology, The First Affiliated Hospital of Nanjing Medical University, and underwent PTBS from March 2016 to February 2020, and according to the presence or absence of postoperative hyperamylasemia or acute pancreatitis, the patients were divided into two groups to analyze incidence rate, severity, and related risk factors. The t-test or the Mann-Whitney U test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. A multivariate logistic regression analysis was performed for the factors with P＜0.1 in the univariate analysis to investigate independent risk factors for hyperamylasemia and acute pancreatitis after PTBS. ResultsAfter PTBS, 55 patients (221%) patients had abnormally elevated serum amylase, among whom 26 (10.4%) were diagnosed with hyperamylasemia and 29 (11.7%) were diagnosed with acute pancreatitis. All patients with acute pancreatitis had mild manifestations. The multivariate logistic regression analysis showed that age ≤60 years (odds ratio ［OR］=2.2, 95% confidence interval ［CI］: 1.07-4.52, P=0033), iodine-125 seed strand implantation (OR=2.8, 95%CI: 1.21-6.45, P=0.016), biliary stent placement across the papilla (OR=6.3, 95%CI: 2.85-1405, P＜0.001), and visualization of the pancreatic duct during surgery (OR=13.9, 95%CI: 5.64-3403, P＜0.001) were risk factors for hyperamylasemia and acute pancreatitis after PTBS. ConclusionHyperamylasemia and acute pancreatitis are relatively common complications after PTBS. Age ≤60 years, iodine-125 seed strand implantation, biliary stent placement across the papilla, and visualization of the pancreatic duct during surgery are independence risk factors for hyperamylasemia and acute pancreatitis after PTBS.

Clinical features of and genetic mutations in two cases of pseudohypoparathyroidism type Ⅰ a(PHP Ⅰ a) with early-onset skin nodules were analyzed.Both of the two patients were males,and their ages at onset were 2 and 3 months respectively.They both presented with early-onset skin nodules as the main clinical manifestation,and were clinically characterized by a round face,short neck and early obesity.Histopathological examination of skin lesions showed subcutaneous ectopic osteogenesis in both patients.The first patient had low blood calcium,high blood phosphorus,high parathyroid hormone (PTH),and gene sequencing showed a heterozygous mutation c.399delT causing a T base deletion at position 399 in exon 5 of the GNAS gene.The second patient had normal blood calcium and phosphorus levels as well as normal PTH levels at early stage,and gene sequencing showed a heterozygous mutation c.939delT causing a T base deletion at position 939 in exon 9 of the GNAS gene.The blood PTH level was found to increase in the second patient after 1-year follow-up.Both the patients were confirmedly diagnosed with PHP Ⅰa.After treatment with vitamin D3,no new skin nodules occurred,and the blood calcium and phosphorus levels returned to normal.

Objective: To investigate the immunohistochemical staining of anaplastic lymphoma kinase (ALK; clone 1A4) in pediatric medulloblastoma (MB). Methods: Molecular subtyping was performed based on the NanoString and sequencing techniques for 44 pediatric MB cases at Children′s Hospital, Zhejiang University School of Medicine from 2014 to 2017. ALK expression was detected with EnVision immunhistochemistry using ALK clone 1A4 on whole section. Statistical analyses were performed to evaluate the correlation of protein expression with molecular subgroups. Results: The age ranged from 0.5 to 13.0 years with an average age of 5.8 years. There were 28 males and 16 females, and 31 classic, 5 desmoplastic nodular, 3 extensive nodular and 5 large cell/anaplastic MBs. Except three cases was unable classified, 41 MBs were classified into the four molecular groups: 5 in WNT group, 12 in SHH group, 9 in Group 3 and 15 in Group 4. Thirteen of 44 MB cases were positive staining for ALK, and the positive rate was 29.5%. Six cases were strong reaction, and 7 cases were weak. The expression of ALK at the protein level was associated with the WNT group (P<0.01). The characteristic perinuclear dot-like staining was only showed in WNT group. Conclusions The ALK immunhistochemistry using antibody clone 1A4 is a useful marker for the molecular subgroup detection of MB. The strong staining and perinuclear dot-like staining indicate as WNT group.

Objective To analyze the clinical efficacy of Yanshu compound sophora flavescens injection (Yanshu injection) combined with paclitaxel and cisplatin (TP) regimen in the treatment of advanced non-small cell lung cancer (NSCLC). Methods One hundred and sixty-two patients with NSCLC admitted to the Department of Oncology of Danyang Hospital of Traditional Chinese Medicine from May 2014 to June 2018 were enrolled, all of their definite diagnosis was based on pathological or cytological examinations, and they were divided into two groups by the administration type, 81 cases in each group. The western medicine treatment group (western group) was treated with TP regimen alone, 3 weeks constituting 1 therapeutic course, and 3 consecutive courses were treated; based on the treatment of western drug TP regimen, the integrated traditional Chinese and western medicine treatment group (combined group) was additionally and simultaneously given Yanshu injection for consecutive 2 weeks. After treatment, the clinical efficacy and incidence of adverse reactions of the two groups were observed. Results The total effective rate in the combined group was significantly higher than that in western group [60.49% (49/81) vs. 40.74% (33/81), P <0.05]; the incidences of adverse events: alopecia, thrombocytopenia, neurotoxicity, leukopenia, nausea and vomiting, and gastrointestinal reaction in the combined group were obviously lower than those in western group [alopecia: 24.69% (20/81) vs. 60.49% (49/81), thrombocytopenia: 23.45% (19/81) vs. 40.74% (33/81), neurotoxicity: 14.81% (12/81) vs. 34.57% (28/81), leukopenia: 17.28% (14/81) vs. 62.96% (51/81), nausea and vomiting: 14.81% (12/81) vs. 60.49% (49/81), gastrointestinal reaction: 27.16% (22/81) vs. 62.96% (51/81), all P < 0.05]. Conclusion Yanshu injection combined with TP regimen is obviously effective in the treatment of advanced NSCLC, thus it is worthy to be applied clinically.

To explore the effects of intrauterine infection on early growth and neurobehavioral development in neonatal rats. (E. coli) was inoculated into uterine cervix of pregnant rats with gestation of 15 d to establish the intrauterine infection model, and the effect on the delivery of pregnant rats was observed. The neonatal rat brain tissue was stained with Hematoxylin-Eosin and the cerebral white matter damage was assessed. Immunohistochemical staining and Western blot analysis were performed to evaluate the expression of glial fibrillary acidic protein (GFAP), 2', 3'-cyclic nucleotide 3'-phosphodiesterase (CNPase) and neurofilament (NF) in pup brains. Birth weight and early growth development indices were monitored,and neurobehavioral tests were performed to access the change of neurobehavioral development in neonatal rats. The white blood cell count increased significantly in the uterus and placenta of the pregnant rats after intrauterine E. coli infection and no significant impact was observed on the delivery of pregnant rats. Weak staining and focal rarefaction of cerebral white matter from rats at P7 in intrauterine infection group were observed. The expression of GFAP markedly increased (<0.05) in infection group, while the level of CNPase and NF in pup brains at P7 significantly decreased (<0.05 or <0.01). Compared with control group, the neonatal rats in infection group had lower birth weight and slower weight gain during the suckling period (<0.05 or <0.01), and the completion times of ear opening, eye opening, surface righting, negative geotaxis, acoustic startle and swimming test in infection group were significantly delayed (<0.05 or <0.01). Intrauterine infection in pregnant rats can induce cerebral white matter damage and retardation of early growth and neurobehavioral development in neonatal rats.
