Diagnostic values of detections of human papillomavirus DNA combined with peripheral blood cyclin A mRNA and cyclin-dependent kinase 2 mRNA for cervical squamous cell carcinoma / 肿瘤研究与临床

Objective:To investigate the diagnostic values of detections of human papillomavirus (HPV) DNA combined with peripheral blood cyclin A mRNA and cyclin-dependent kinase 2 (CDK2) mRNA for cervical squamous cell carcinoma.Methods:Eighty patients with cervical squamous cell carcinoma treated in Jiangyin Hospital of Traditional Chinese Medicine from January 2018 to October 2021 were selected as the research objects. Eighty patients with benign cervical lesions such as cervicitis treated in the same period were selected as the control. The levels of HPV-DNA in paraffin-embedded tissues of cervical squamous cell carcinoma were detected by gene chip, and the mRNA expression levels of cyclin A and CDK2 in peripheral blood monocytes were detected by reverse transcription polymerase chain reaction. The related factors of cervical squamous cell carcinoma were analyzed by multivariate logistic regression. Taking the results of pathological biopsy as the gold standard, the diagnostic efficacy of HPV-DNA, peripheral blood cyclin A mRNA and CDK2 mRNA single and combined detection for cervical squamous cell carcinoma were determined by receiver operating characteristic (ROC) curve.Results:The positive rate of HPV-DNA in patients with cervical squamous cell carcinoma was higher than that in the control group [75.00% (60/80) vs. 13.75% (11/80), P < 0.05]; the relative expressions of cyclin A mRNA and CDK2 mRNA in patients with cervical squamous cell carcinoma were 0.26±0.08 and 1.49±0.07, respectively, which were higher than those in the control group (0.11±0.03 and 1.14±0.06), and the differences were statistically significant (both P < 0.05). Multivariate logistic regression analysis showed that the number of induced abortions > 1 ( OR = 3.093, 95% CI 1.386-6.899, P = 0.021), the age of first birth ≤18 years old ( OR = 3.684, 95% CI 1.651-8.219, P = 0.013), the positive HPV-DNA ( OR = 4.125, 95% CI 1.849-9.202, P = 0.001), the increased relative expression of cyclin A mRNA in peripheral blood ( OR = 3.800, 95% CI 1.703-8.478, P = 0.006) and the increased relative expression of CDK2 mRNA in peripheral blood ( OR = 4.821, 95% CI 2.161-10.756, P = 0.008) were risk factors for the occurrence of cervical squamous cell carcinoma. ROC curve analysis showed that the area under the curve (AUC) of HPV-DNA, peripheral blood cyclin A mRNA and CDK2 mRNA in single and combined diagnosis of cervical squamous cell carcinoma were 0.769 (95% CI 0.700-0.838), 0.756 (95% CI 0.688-0.823), 0.755 (95% CI 0.689-0.820) and 0.827 (95% CI 0.766-0.888), respectively. Conclusions:HPV-DNA and the levels of cyclin A mRNA and CDK2 mRNA in peripheral blood can be used to assist in the diagnosis of cervical squamous cell carcinoma, and the combination of the three has high diagnostic efficiency.

Inflammatory bowel disease with growth hormone deficiency in adolescents: an analysis of 4 cases and literature review / 中国当代儿科杂志

Inflammatory bowel disease (IBD) is a chronic recurrent non-specific inflammatory disease in the intestinal tract. About 10%-56% of children with Crohn's disease and about 10% of children with ulcerative colitis have growth retardation. This study reports four adolescents with IBD and growth hormone deficiency who were diagnosed with Crohn's disease. There were three boys and one girl, with an age of 11.0-13.9 years and a disease duration of 11-85 months at diagnosis. The four patients had the involvement of the small intestine only, the colon only, both the small intestine and the upper gastrointestinal tract, and both the small intestine and the colon respectively. The pediatric Crohn's disease activity index ranged from 27.5 to 45 points. All four patients had a height-for-age Z-score (HAZ) of <-2, and the growth hormone provocative test suggested growth hormone deficiency. Of all four patients, two received recombinant human growth hormone combined with infliximab, one received infliximab only, and one received recombinant human growth hormone combined with mercaptopurine. All four patients had an improvement in HAZ after treatment.

Clinical features and prognosis of gastrointestinal injury due to foreign bodies in the upper gastrointestinal tract in children: a retrospective analysis of 217 cases / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the clinical features and prognosis of gastrointestinal injury caused by foreign bodies in the upper gastrointestinal tract in children.</p><p><b>METHODS</b>A retrospective analysis was performed for the clinical data of 217 children who were diagnosed with foreign bodies in the upper gastrointestinal tract complicated by gastrointestinal injury by gastroscopy from January 2011 to December 2016, including clinical features, gastroscopic findings, complications, and prognosis.</p><p><b>RESULTS</b>Among the 217 children, 114 (52.5%) were aged 1-3 years. The most common foreign body was coin (99/217, 45.6%), followed by hard/sharp-edged food (45/217, 20.7%) and metal (35/217, 16.1%). The most common gastrointestinal mucosal injury was ulceration (43.8%), followed by erosion (33.2%). Compared with other foreign bodies, button cells were significantly more likely to cause esophageal perforation (P<0.01). The esophagus was the most commonly injured organ (207/217, 95.4%). Of all the 217 children, 24 (11.1%) experienced infection. The children with perforation caused by foreign bodies had a significantly higher incidence rate of infection than those with ulceration caused by foreign bodies (P=0.003). Of all the 217 children, 204 (94.0%) underwent successful endoscopic removal of foreign bodies. Among these children, 98 were hospitalized due to severe mucosal injury and were given anti-infective therapy, antacids, and supportive care including enteral nutrition through a nasogastric tube and/or parenteral nutrition. Of all the children, 10 left the hospital and were lost to follow-up, and all the other children were improved and discharged.</p><p><b>CONCLUSIONS</b>Most cases of foreign bodies in the upper gastrointestinal tract occur at 1-3 years of age. Coin, hard/sharp-edged food, and metal are the most common foreign bodies. Button cells are more likely to cause esophageal perforation. The incidence rate of secondary infection increases with the increasing severity of gastrointestinal mucosal injury. Children undergoing endoscopic removal of foreign bodies and enteral nutrition through a nasogastric tube tend to have a good prognosis.</p>

Timing of nasojejunal feeding tube placement and enteral nutrition in children with acute pancreatitis / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the impact of timing of nasojejunal feeding tube placement and enteral nutrition on clinical outcomes in children with acute pancreatitis.</p><p><b>METHODS</b>A retrospective analysis was performed on the clinical data of 31 children with acute pancreatitis, who received nasojejunal feeding between January 2008 and July 2013, to investigate the relationship of abdominal symptoms/signs and serum amylase level with the tolerability of catheterization and success rate of enteral nutrition. The treatment outcome and incidence of adverse reactions and complications were compared between the early enteral nutrition group ( ≤7 days from the onset of the disease) and late enteral nutrition group (>7 days from the onset of the disease).</p><p><b>RESULTS</b>Abdominal symptoms/signs and serum amylase level were independent of the tolerable rate of catheterization and success rate of enteral nutrition. Compared with the late enteral nutrition group, the early enteral nutrition group had a shortened time to normal serum amylase level, significantly reduced incidence of systemic complications, length of hospital stay, and hospitalization expenses, and less weight gain. The tolerable rate of catheterization and success rate of enteral nutrition showed no significant difference between the two groups. Similarly, no significant differences were found in the increase in albumin level after enteral nutrition, duration of enteral nutrition, incidence of adverse reactions, and incidence of local complications.</p><p><b>CONCLUSIONS</b>Abdominal symptoms/signs and serum amylase level cannot be used as a measure of whether nasojejunal feeding tube placement and enteral nutrition can be performed. Early enteral nutrition can better improve clinical outcomes in children with acute pancreatitis, and it is feasible.</p>

Value of nasojejunal nutrition in the treatment of children with acute pancreatitis / 中华儿科杂志

<p><b>OBJECTIVE</b>To evaluate the feasibility and effectiveness of placement of nasojejunal feeding tube and nasojejunal nutrition feeding in children with acute pancreatitis.</p><p><b>METHOD</b>Twenty-two patients (of whom 13 had severe acute pancreatitis and 9 acute mild pancreatitis) who needed nutritional intervention were selected. They were from Department of Gastroenterology and Surgery during the years 2009 - 2012, and they were at high nutritional risk after STONGkid nutrition risk screening. The average age of them was 5 - 15 years (9.1 years ± 2.8 years). Assisted by endoscopy, the nasojejunal feeding tube was placed in 22 of 24 patients (in 2 cases of recurrent pancreatitis the tubes were placed again after extubation). Besides the use of regular fasting, antacids, inhibitors of trypsin secretion, and anti-infective treatment, 23 cases of all children got nasojejunal nutrition treatment as well. The outcome measures included the success rate, complications of endoscope-assisted nasojejunal tube placement. The children's tolerance and nutrition indicators (weight, blood lymphocytes count, erythrocytes count, serum albumin, serum creatinine, blood urea nitrogen) were observed before and after enteral nutrition therapy.</p><p><b>RESULT</b>Malnutrition evaluation was done 24 times before treatment among 22 patients, incidence of malnutrition was 33% in 22 cases. Placement of nasojejunal tube placement was attempted for a total of 24 times and was successful on first placement in 22 cases, in two cases the placement was successful on the second placement, so the success rate of the first attempt for placement was 92%. No significant complications were observed in any of the cases. Twenty-three of 24 cases were given standardized enteral nutrition (one case was not given enteral nutrition therapy but underwent ERCP due to obstructive jaundice). Twenty-two of 23 cases could tolerate enteral nutrition well, only 1 case was unable to tolerate enteral nutrition due to the pancreas schizophrenia, paralytic ileus. The treatment of jejunal feeding success rate was 96%. The feeding duration was 2 - 74 d (27.0 d ± 18.3 d). The adverse reactions include plugging of the tube in two cases, constipation in two cases, five cases had abdominal pain, diarrhea in 2 cases, vomiting in 2 cases and 1 case of jejunum retention. No case had nasopharynx ulcers, gastrointestinal perforation, gastrointestinal bleeding, re-feeding syndrome and infection etc. Blood erythrocytes count, serum creatinine, blood urea nitrogen were not significantly changed. Twenty of 23 cases were cured, 2 cases were improved and 1 case was unchanged.</p><p><b>CONCLUSION</b>Endoscope-assisted nasojejunal tube placement for children with acute pancreatitis is safe and feasible. Nasojejunal nutrition therapy is effective for acute pancreatitis patients who are at severe nutritional risk, especially for the improvement of the nutritional status of children.</p>

Yield of CD34(+) cells in graft can be increased significantly by G-CSF used at appropriate time after chemotherapy for AutoPBSCT / 中国实验血液学杂志

This study was aimed to investigate the influence of timing using G-CSF after chemotherapy on graft yield of mobilized peripheral blood stem cells for autoPBSCT. 39 patients with lymphoma or multiple myeloma (MM) received the same chemotherapy mobilization regimen, including CTX 400 mg/m² d1; VLB 2 mg/m(2) d1; Ara-C 60 mg/m ²× d1-5; VP-16 60 mg/m² × d1-5; and prednisone 40 mg/m² × d1-5. The historical control group (12 cases) received G-CSF subcutaneously (filgrastim) at the first restoration after the initial nadir of the peripheral WBC count. The experimental group (27 cases) received G-CSF during the steady rise of the WBC count (end of fluctuating after initial nadir). G-CSF was given in a single daily subcutaneous dose of 5 µg/kg until the final PBSC apheresis. When the peripheral WBC and mononuclear cell (MNC) counts reached 10 × 10⁹/L and 1.0 × 10⁹/L respectively, leukapheresis was carried out using the COBE Spectra blood cell separator. The results indicated that despite there was comparable treatment with alkylating agents between 2 groups, a significantly increased yield of CD34 positive cells was observed in the experimental group (26.4 × 10⁶/kg), as compared to the historical control group (3.1 × 10⁶/kg) (p = 0.0031). It is concluded that the appropriate timing for the use G-CSF mobilization after chemotherapy is important to increase the CD34(+) cell yield in auto-graft.

Clinical manifestations and endoscopic features of abdominal type Henoch purpura in children / 中华儿科杂志

<p><b>OBJECTIVE</b>To investigate the clinical manifestations and endoscopic features of abdominal type Henoch purpura in children and improve the diagnostic level.</p><p><b>METHODS</b>Retrospective review was made on the clinical, endoscopic and histopathological features of 57 cases of children with Henoch purpura abdominal type who had been hospitalized from Jan. 2002 to May 2007. Upper gastrointestinal endoscopy was performed in all cases. All the cases had various digestive system symptoms without cutaneous purpura before endoscopy. Mucosal specimens were taken from sinus ventriculi and duodenum for histopathological analysis. Helicobacter pylori (H.pylori) infection was identified by rapid urease test and histology, and diagnosis of H.pylori infection was made when both were positive.</p><p><b>RESULTS</b>The common gastrointestinal symptoms of Henoch purpura were abdominal pain (46 cases), vomiting (32 cases), hematochezia (11 cases), diarrhea (4 cases) and abdominal distention (1 case). Three cases had arthralgia and joint swelling. The main laboratory findings were increased peripheral white blood cells (33 cases, 57.9%), 1/5 of cases had elevated C reactive protein (CRP), low serum albumin and seroperitoneum. Endoscopy demonstrated the damages to the mucosa, which varied from congestion, edema, petechia and ecchymosis (37 cases, 64.9%) to erosive and multiple ulcers (14 cases, 24.6%), granulation of mucosa in descendent duodenum (4 cases, 7.0%), and diffuse hemorrhage of mucosa (2 cases, 3.5%). The upper gastrointestinal endoscopy showed that the commonest and most serious position involved was the descendent duodenum (55 cases, 96.5%), followed by duodenal bulb (32 cases, 56.1%) and stomach (18 cases, 36.1%), esophagus was less involved (1 case, 1.8%). Histological manifestations showed swollen vascular endothelial cells of capillary vessels and small blood vessels, fibrotic necrosis of small vessels and bleeding, diffuse perivascular lymphocytic and neutrophilic infiltration and nuclear debris in mucosa and submucosa. Three cases (5.3%) were found infected with H. pylori. In 49 cases (86.0%) cutaneous purpura appeared 1 - 7 days after endoscopy. Eight cases had no cutaneous purpura until they left hospital. Two cases were lost to follow up and 6 cases (10.5%) remained free from cutaneous purpura were followed up until now (1 - 5 years).</p><p><b>CONCLUSION</b>Descending duodenum is the commonest and most serious position of upper gastrointestinal tract involved in Henoch purpura. Upper gastrointestinal endoscopy with the mucosal biopsy are useful for the early diagnosis of Henoch purpura.</p>
