ObjectiveTo investigate the value of FibroScan combined with gamma-glutamyl transpeptidase-to-platelet ratio (GPR) in predicting liver fibrosis stage in patients with chronic hepatitis B (CHB). MethodsA total of 278 patients who were diagnosed with CHB by liver biopsy in Guangzhou Eighth People’s Hospital from January 2012 to December 2016 were enrolled. The value of GPR and FibroScan used alone or in combination in predicting liver fibrosis stage (F0-F4) was analyzed. The Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups and the Mann-Whitney U test was used for further comparison between two groups. The Spearman’s correlation coefficient was used for correlation analysis. The area under the receiver operating characteristic curve (AUC) was used to evaluate liver fibrosis stage. ResultsWith liver biopsy as the gold standard, of all patients, 50 had stage F1 fibrosis, 104 had stage F2 fibrosis, 92 had stage F3 fibrosis, and 32 had stage F4 fibrosis. Liver stiffness measurement by FibroScan gradually increased with the increase in liver fibrosis stage (P＜0.05), and GPR also increased gradually in patients with stage F1, F2, and F3 liver fibrosis (P＜0.05). GPR and FibroScan were positively correlated with liver fibrosis (r=0.419 and 0.481, both P＜0.001), and GPR was positively correlated with FibroScan (r=0.436, P＜0.001). According to AUC, FibroScan combined with GPR had a better diagnostic efficiency than FibroScan (0.793 vs 0.739, Z=3.044, P=0.002) or GPR (0.793 vs 0.740, Z=2.389, P=0.037) alone in predicting progressive liver fibrosis (≥F3); FibroScan combined with GPR had a better diagnostic efficiency than GPR alone (0.782 vs 0714, Z=2.130, P=0.033) in predicting marked liver fibrosis (≥F2). ConclusionFibroScan combined with GPR has a certain advantage in predicting progressive liver fibrosis (≥F3) in CHB patients and can improve diagnostic efficiency.

Objective To investigate the predictive value of dynamic monitoring of transcutaneous oxygen partial pressure [p_tc(O₂)], transcutaneous carbon dioxide partial pressure [p_tc(CO₂)], serum amyloid A (SAA), and interleukin-6 (IL-6) levels in predicting bronchopulmonary dysplasia (BPD) in neonates with neonatal respiratory distress syndrome (NRDS). Methods A total of 240 NRDS patients were selected as the research subjects and divided into BPD group (108 cases) and non-BPD group (132 cases) based on whether BPD occurred. The levels of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 were compared between the two groups on the 1st, 7th, and 14th day after birth. Spearman correlation analysis was used to explore the correlation between each indicator and the degree of illness. The relative risk (RR) and 95% confidence interval (CI) were used to evaluate the impact of each indicator on BPD in NRDS patients. Receiver operating characteristic (ROC) curves and decision curve analysis were used to evaluate the predictive efficacy and clinical net benefit of each indicator for BPD. Results On the 1st day after birth, there were no statistically significant differences in p_tc(O₂), p_tc(CO₂), serum SAA, and IL-6 levels between the two groups (P>0.05). On the 7th and 14th day after birth, the p_tc(O₂) in the BPD group was lower than that in the non-BPD group, while the p_tc(CO₂) and serum SAA, IL-6 levels were higher than those in the non-BPD group (P < 0.05). Correlation analysis results showed that the degree of BPD in children was negatively correlated with p_tc(O₂) on the 7th day after birth (r=-0.724, P < 0.05), and positively correlated with p_tc(CO₂), SAA, and IL-6 on the 7th day after birth (r=0.635, 0.830, 0.715, P < 0.05). The degree of pulmonary dysfunction in children was negatively correlated with p_tc(O₂) on the 7th day after birth (r=-0.719, P < 0.05), and positively correlated with p_tc(CO₂), SAA, and IL-6 on the 7th day after birth (r=0.673, 0.756, 0.696, P < 0.05). On the 7th day after birth, the p_tc(O₂) of BPD patients was negatively correlated with SAA and IL-6 (r=-0.605, -0.623, P < 0.05), while p_tc(CO₂) was positively correlated with SAA and IL-6 (r=0.618, 0.650, P < 0.05). ROC curve showed that the combined prediction of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 on the 7th day after birth for NRDS complicated with BPD was better than the individual prediction of the four indicators, with an area under the curve of 0.938 (95%CI, 0.899 to 0.965). The risk of BPD in high-expression of p_tc(CO₂), SAA, and IL-6 was 2.256, 1.668, and 1.667 times higher than that in low-expression, respectively. The risk of BPD in high-expression of p_tc(O₂) was 0.568 times higher than that in low-expression. The decision curve analysis showed that when the threshold value was within the range of 0.2 to 0.9, the combined model of p_tc(O₂), p_tc(CO₂), SAA, and IL-6 was superior to the individual prediction in predicting the net benefit rate of BPD in NRDS patients on the 7th day after birth. Conclusion The severity of NRDS complicated with BPD is closely related to p_tc(O₂), p_tc(CO₂), SAA, and IL-6, and the combined detection of the four indicators can help improve the predictive efficacy and net benefit rate of NRDS complicated with BPD.

Objective To investigate the distribution of the thalassemia genotypes and the characteristics of blood cell parameters in Changshou District,Chongqing.Methods Totally 4126 samples sent to our hospital were studied from June 2018 to March 2023.All samples were detected for thalassemia genotype and blood cells.The parameters of blood cells:redblood cell(RBC),hemoglobin(Hb),mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC),red blood cell distribution width CV(RDW-CV),red blood cell distribution width SD(RDW-SD)were detected.Gap polymerase chain reaction(Gap-PCR)combined with reverse dot blot hybridization were used to detect alpha and beta thalassemia genotype.The rate and distribution characteristics of thalassemia gene in Changshou district were analyzed.Results Among 4126 samples,408 cases of α and β thalassemia were detected,accounting for 9.89%.Among these,there were 255 α-thalassemia cases.-α3.7/αα was the most common genotype.Two cases of--αSEA/-α3.7 and one cases of--SEA/HKαα were also detected.There were 153 cases of β-thalassemia and CD17 accounted for the highest proportion.The date of MCV,MCH,MCHC in-α3.7/αα,--SEA/αα,-α4.2/αα and ααCS/αα groups was significantly difference compared with control group(P<0.05).Parameters of MCV and MCH in CD17,CD41-42 and Ivs-2-654 groups were lower than those in control group(P<0.05),while RBC,RDW-CV and RDW-SD were higher than those in control group,the difference was statistically significant.Conclusion The most common genotype in thalassemia were-α3.7/αα,--SEA/αα,-α4.2/αα,CD17,CD41-42 and Ivs-2-654 in Changshou District,Chongqing.The parameters of MCV,MCHC,MCH,Hb,RBC,RDW-CV and RDW-SD have important clinical significance for the screening of thalassemia.

Objective: To investigate the correlation between the severity of peptic ulcer bleeding (PUB) and the serum antibody typing of Helicobacter pylori (H.pylori). Methods: From January 1, 2009 to December 31, 2018, at Guangzhou First People′s Hospital, 1 444 patients diagnosed with PUB and received H. pylori serum antibody test at the same time were enrolled and divided into high-risk group (324 cases) and low-risk group (1 120 cases) according to Forrest classification, and according to recurrent bleeding, the patients were divided into recurrent bleeding group (32 cases) and non-rebleeding group (1 412 cases). Serum H. pylori specific antibodies cytotoxin-associated gene A (CagA), vacuolating cytotoxin A (VacA) and urease were detected by protein array. The correlation between H. pylori positive rate, H. pylori type, PUB and rebleeding were analyzed. Chi-square test and logistic regression analysis were used for statistical analysis. Results: Among 1 444 PUB patients, there were 709 patients with gastric ulcer bleeding (GUB) and 735 patients with duodenal ulcer bleeding (DUB). Previous history of peptic ulcer disease (odds ratio (OR)=1.501, P=0.006), the maximum diameter of ulcer over 2 cm (OR=2.484, P<0.01) and H. pylori infection (OR=1.508, P=0.005) were independent risk factors of the severity of PUB. The total H. pylori positive rate was 68.49% (989/1 444), H. pylori type Ⅰ was the main type. Of which, 61.34% (549/895) were CagA and VacA double positive strains, 31.73% (284/895) were VacA single positive bacteria and CagA single positive bacteria was only 6.93% (62/895). The positive rate of H. pylori of high-risk group was higher than that of low-risk group (75.31%, 244/324 vs. 66.52%, 745/1 120), and the difference was statistically significant (χ²=8.999, P=0.004). In addition, the more serious Forrest classification, the higher the detection rate of H. pylori, and the difference was statistically significant (χ²=11.840, P=0.037). There was no significant difference in the positive rate of H. pylori between recurrent bleeding group and non-rebleeding group (81.25%, 26/32 vs. 68.20%, 963/1 412; χ²=2.469, P>0.05). According to H. pylori antibody type, H. pylori type Ⅰ infection was mainly in both high-risk group and low-risk group. The positive rate of H. pylori type Ⅰ strain of high-risk group was higher than that of low-risk group (67.28%, 218/324 vs. 60.45%, 677/1 120), and the difference was statistically significant (χ²=4.986, P=0.026). There was no statistically significant difference in the positive rate of H. pylori between GUB group and DUB group (68.41%, 485/709 vs. 68.57%, 504/735; χ²=0.005, P>0.05). Conclusions The infection of H. pylori is positively correlated with the severity of PUB, but not correlated with early ulcer rebleeding. H. pylori type Ⅰ is the main pathogenic strain of GUB and DUB, and CagA and VacA double positive strain is the most common strain.

Methods: Data were collected from the American College of Surgeons National Surgical Quality Improvement Program dataset from 2011 to 2018. The cohort was divided into patients with LOS up to 1 day (LOS ≤1 day), defined as same day or next-morning discharge, and patients with LOS >1 day (LOS >1 day). Univariable and multivariable regression analyses were performed to evaluate predictors of LOS >1 day. Propensity-score matching was performed to compare pre- and postdischarge complication rates. Results: A total of 12,664 eligible patients with TLIF were identified, of which 14.8% had LOS ≤1 day and 85.2% had LOS >1 day. LOS >1 day was positively associated with female sex, Hispanic ethnicity, diagnosis of spondylolisthesis, American Society of Anesthesiologists classification 3, and operation length of >150 minutes. Patients with LOS >1 day were more likely to undergo intraoperative/postoperative blood transfusion (0.3% vs. 4.5%, p<0.001) and reoperation (0.1% vs. 0.6%, p=0.004). No significant differences in the rates of postdischarge complications were found between the matched groups. Conclusions Patients with worsened preoperative status, preoperative diagnosis of spondylolisthesis, and prolonged operative time are more likely to require prolonged hospitalization and blood transfusions and undergo unplanned reoperation. To reduce the risk of prolonged hospitalization and associated complications, patients indicated for TLIF should be carefully selected.

Objective: To investigate the histological type and clinicopathological characteristics of the craniocerebral slope tumors with chondromucinous features. Methods: Retrospective analysis was conducted to analyze chondromucinous tumors in the slope area diagnosed at Henan Provincial People′s Hospital from October 2011 to June 2018. Relevant clinical and pathological data were reviewed, and immunohistochemistry was used to investigate the immunophenotype of the tumors. Results: Eight cases were identified, including 4 males and 4 females with patient age ranging from 20 to 48 years. Histologically, there were 1 case of chordoid meningioma, 1 chondromyxoid fibroma, 1 mucinous chondrosarcoma, 1 Maffucci syndrome, and 4 chondroid chordomas. Conclusion Chondromucinous tumors of the slope area include chordoma, chordoid meningioma, chondromyxoid fibroma, and myxoid chondrosarcoma and their correct diagnosis is mainly based on the morphological characteristics, immunophenotype and comprehensive analysis of clinical data.

Objective To explore the application effect of recombinant human granulocyte colony stimulating factor(rhG-CSF)in the treatment of chemotherapy-induced oral mucositis in children.Methods Totally 60 children with chemotherapy-induced oral mucositis who underwent chemotherapy in the tumor surgery of our hospital from January 2020 to June 2022 were randomly divided into two groups,30 cases each.The control group was given physiological saline oral care,and the experimental group was given rhG-CSF oral care.Compare the intervention effect,oral mucositis grading,quality of life[short form of health survey(SF-36)]and nursing satisfaction of parents of the two groups.Results The total effective rate of the experimental group was higher than that of the control group(P<0.05).After 5 days of intervention,the score of oral mucositis in the experimental group was better than that in the control group(P<0.05).After 5 days of intervention,the SF-36 score of children in the two groups was higher than that before intervention,and that in the experimental group was higher than that in the control group(P<0.05).The parents'satisfaction in the experimental group was higher than that in the control group(P<0.05).Conclusion rhG-CSF oral care can effectively improve the intervention effect of chemotherapy-induced oral mucositis in children,reduce the grade of oral mucositis,improve the quality of life of children,and improve the nursing satisfaction of parents of children.

Abstract OBJECTIVE To analyze the different therapeutic effects of different formulations of recombinant human growth hormone on idiopathic short stature and the related factors before treatment. METHODS Retrospective analysis was performed on children aged 4-8 years who were diagnosed as idiopathic short stature at the Child Health Department of Sichuan Maternal and Child Health Care Hospital from January 2020 to December 2021 and treated with different formulation of recombinant human growth hormone. The changes of height growth value and growth factor levels of children in different groups during different treatment periods were compared. At the same time, Logistic regression analysis was carried out on the related factors affecting the effect of height growth before treatment. RESULTS There was no significant difference in height, IGF-1 and IGF-BP3 growth between the two groups at each stage of treatment, except for the statistical difference in IGF-BP3 increment at the third month of treatment(P<0.05); The age of treatment had an effect on the height growth outcome of children, and there was statistical significance(OR=0.258, 95%CI 0.109-0.609, P=0.002). The remaining factors had no obvious influence. CONCLUSION There is no difference in the therapeutic effect of different formulation of recombinant human growth hormone on idiopathic short stature. The age of beginning use is the main factor that affects the effect of using growth hormone.

Objective RegIV, which is the latest member of the regenerative gene family, has been found to be closely related to the development of various tumors, but rarely reported in invasive breast cancer. This article is intended to explore the expression levels of regenerative factor 4(regeneration islet-derived family, member 4, RegIV), and the correlation with clinicopathological features and prognosis in 4 molecular subtypes of breast cancer(LA, LB,HER-2+, TNBC). Methods Pathological data of 284 breast cancer patients from March 2011 to October 2017 in the department of pathology, Lianyungang first people’s hospital were collected. To analyze the expression of RegIV in different molecular subtypes (LA, LB, HER-2+, TNBC) and its relationship with clinicopathological features, we analyzed the expression level of RegIVmRNA in breast cancer and its prognosis of patients. Results The positive rates of Reg IV in Luminal A group, Luminal B group, HER-2 positive group and triple negative breast cancer were 52.11%（37/71）, 50.00%（42/84）, 65.22%（45/69）and 20.00%（12/60）,which was statistically significant when comparing them in pairs(P<0.01). The expression of RegIV was associated with tumor diameter, lymph node metastasis, TNM stage(P<0.01). The recurrence risk of breast cancer patients with high RegIV expression was lower than those with low RegIV expression (HR=0.59,95%CI:0.50-0.69). Further analysis found that the recurrence risk of LA breast cancer patients with high RegIV expression (HR=0.63,95%CI:0.48-0.82), and so it was with LB(HR=0.56,95%CI:0.40-0.76) and TNBC(HR=0.51,95%CI:0.36-0.71). Conclusion RegIV can provide reference for molecular subtypes diagnosis and it may be one of the indicators to evaluate the prognosis of breast cancer patients.

Objective: To investigate the clinical data of children with inflammatory bowel disease (IBD) retrospectively, including Crohn′s disease (CD) and ulcerative colitis (UC) and identify the clinical characteristics and trends of change. Method: Clinical data of hospitalized patients diagnosed as IBD in Beijing Children′s Hospital from January 2000 to December 2014 were collected and retrospectively analyzed. Patients were divided into six groups based on type of disease and year of admission: Group A1(CD, 2000-2004) included 12 patients, Group B1(CD, 2005-2009) included 11, Group C1(CD, 2010-2014) included 51; Group A2(UC, 2000-2004) included 17, Group B2(UC, 2005-2009) included 25, Group C2(UC, 2010-2014) included 68. Result: A total of 184 IBD patients were included in the study, 74 had CD and 110 had UC. The hospitalization constituent ratio of CD increased from 0.6/10 000 in Year 2000 to 2.9/10 000 in Year 2014. The hospitalization constituent ratio of UC increased from 0.5/10 000 in Year 2001 to 3.9/10 000 in Year 2014. The hospitalization constituent ratios of CD and UC both increased gradually(P<0.05). Up to 61.4%(113/184) of IBD patients belong to early onset IBD, furthermore the very early onset IBD and infantile IBD accounted for 41.8%(77/184) and 26.6%(49/184) respectively. For CD, ileocolonic type(47.3%, 35/74) and non-structuring, non-penetrating type (67.6%, 50/74) were more common. Perianal disease occured in 31.1%(23/74) of CD patients; 81.1%(60/74) of CD patients had moderate/severe activity. For UC, pancolitis type(59.1%, 65/110) was more common. There were no significant changes for location of pathological change, disease behavior, activity degree of CD, extent of UC lesion and incidence of surgery, intestinal perforation and hemorrhage of gastrointestinal tract for IBD in the past 15 years(P>0.05). Severe UC(S3) was more common in Group A2(64.7%, 11/17), but moderate UC(S2) was more common in Group C2(48.5%, 33/68), the difference was statistically significant (P=0.001 7). Conclusion During the past 15 years, the hospitalization constituent ratio for IBD in our hospital showed a growing trend. The ratio of infantile IBD and very early onset IBD was high. For CD, perianal disease was commonly seen and most patients had moderate/severe activity. The surgery rate and incidence of intestinal obstruction and perforation were higher in the CD patients than UC patients. For UC, the lesions were more extensively combined with higher disease activity.
