Objective: To analyze the clinical characteristics and complications of esophageal foreign bodies of button battery ingestion in children. Methods: A retrospective descriptive study included 83 children who were hospitalized in our hospital on account of button battery ingestion from January 2011 to December 2021. There were 50 males (60.2%) and 33 females (39.8%). The age ranged from 7.6 months to one month off 10 years, with a median age of 18 months. The data of patient demographics and time from ingestion to admission, location, symptoms, management, complications, and follow-up outcome were recorded. SPSS17.0 software was used for statistical analysis. Results: Seventy-two children (86.7%) were younger than 3 years old. The time from ingestion to admission ranged from 1 h to 2 months, with a median time of 8 h. Among the 63 children who were first diagnosed in our hospital, the most common clinical symptoms were nausea and vomiting (32 cases, 50.8%), dysphagia (31 cases, 49.2%), salivation (11 cases, 17.5%) and fever (10 cases, 15.9%). Seventy-three of 83 cases had complete preoperative diagnostic tests, and 55 cases (75.3%) were diagnosed by X-ray. In 56 cases (76.7%), the foreign badies were impacted in the upper third of esophagus. In 72 cases (86.7%), the foreign badies were removed by rigid esophagoscopy. 23 (27.7%) had serious complications, including tracheoesophageal fistula in 15 cases(TEF;65.2%), vocal cord paralysis (VCP;34.8%) in 8 cases, esophageal perforation in 3 cases (EP;13.0%), hemorrhage in 3 cases(13.0%), mediastinitis in 3 cases (13%), and periesophageal abscess in 1 case (4.3%). There were significant differences in the exposure time of foreign bodies and unwitnessed ingestion by guardians in the complications group (P<0.05). 2 cases died (2.4%)respectively due to arterial esophageal fistula bleeding and respiratory failure caused by stent displacement during the treatment of tracheoesophageal fistula. Conclusion: Accidental button battery ingestion can be life-threatening. and it mostly happens in children under 3 years old. Serious complications may happen cause of non-specific clinical manifestations and unwitnessed ingestions. Anterior and lateral chest X-ray is the first examination choice. Tracheoesophageal fistula is the most common serious complication.

OBJECTIVE: To systematically review the effect of probiotic supplementation during pregnancy and infancy in preventing atopic dermatitis in children. METHODS: RevMan5.3 was used to perform a Meta analysis of randomized controlled trials on the effect of probiotic supplementation during pregnancy and infancy in preventing atopic dermatitis in children published between January 2008 and May 2018 across the world. A subgroup analysis was conducted according to the type of probiotics for intervention, follow-up time, time of probiotic supplementation, and study areas. RESULTS: A total of 22 articles were selected, with 3 280 cases in the intervention group and 3 281 cases in the control group. The results of pooled effect size showed that probiotic supplementation during pregnancy and/or infancy significantly reduced the incidence rate of atopic dermatitis (RR=0.81, 95%CI: 0.70-0.93, P<0.05). According to the subgroup analysis, the intervention with Lactobacillus and Bifidobacterium had a significant effect (RR=0.68, 95%CI: 0.52-0.90, P<0.05); probiotic supplementation during both pregnancy and infancy also had a significant effect (RR=0.77, 95%CI: 0.66-0.90, P<0.05); probiotic supplementation during pregnancy and/or infancy had a better effect in preventing atopic dermatitis in children aged ≤2 years than in those aged >2 years (RR=0.74, 95%CI: 0.61-0.90, P<0.05); probiotic supplementation had a significant effect in Australia (RR=0.83, 95%CI: 0.73-0.96, P<0.05) and Europe/the United States (RR=0.74, 95%CI: 0.61-0.91, P<0.05). Heterogeneity was mainly due to follow-up time (I=62.7%) and time of probiotic supplementation (I=53.5%). CONCLUSIONS Probiotic supplementation during pregnancy and infancy helps to prevent atopic dermatitis in children, and mixed Lactobacillus-Bifidobacterium intervention has a better effect.

BACKGROUNDOsteoporosis (OP) is a common bone disease, which adversely affects life quality. Effective treatments are necessary to combat both the loss and fracture of bone. Recent studies indicated that caffeic acid phenethyl ester (CAPE) is a natural chemical compound from honeybee propolis which is capable of attenuating osteoclastogenesis and bone resorption. Therefore, this study aimed to investigate the effect of CAPE on bone loss in OP mice using micro-computed tomography (CT) and histology.

METHODSEighteen mice were prepared and evenly divided into three groups. The six mice in the sham+PBS group did not undergo ovariectomy and were intraperitoneally injected with PBS during the curing period. Twelve mice were ovariectomized (OVX) to induce OP. Six of them in the OVX+CAPE group were intraperitoneally injected with 0.5 mg/kg CAPE twice per week for 4 weeks after ovariectomy. The other six OVX mice in OVX+PBS group were treated with PBS. All the mice were sacrificed 4 weeks after ovariectomy. The tibias were bilaterally excised for micro-CT scan and histological analysis. The Mann-Whitney U test was used to test the statistical differences among groups.

RESULTSBone loss occurred in OVX mice. Compared with the sham+PBS group, mice in the OVX+PBS group exhibited a significant decrease in bone mineral density (BMD, P < 0.05), bone volume fraction (BV/TV, P < 0.01), trabecular thickness (Tb.Th, P < 0.05), and trabecular number (Tb.N, P < 0.01), as well as a non-insignificant increase in the number of osteoclasts (N.Oc/B.Pm). With CAPE treatment, the microarchitecture of the tibial metaphyses was significantly improved with a reduction of osteoclast formation. Compared with the OVX+PBS group, BV/TV in the OVX+CAPE group was significantly increased by 33.9% (P < 0.05).

CONCLUSIONCAPE therapy results in the protection of bone loss induced by OVX.

Objective To determine the influences of Mannose binding protein (MBP) gene polymorphisms on HBV DNA loads and on the progression of liver disease in patients with chronic HBV infeclion.Method The Codons on 54 MBP gene polymorphisms and HBV DNA loads in a cohort of 395 patients with chronic HBV infection,including 244 with chronic hepatitis B (CHB),151 with liver cirrhosis(LC) and 88 normal controls were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and fluorescent quantitative PCR (FQ-PCR).Result The MBP genotype frequencies of GGC/GAC and alleles genetic frequencies of GAC in CHB group showed no significant differences comparing to the normal control group ( P ＞ 0.05 ).The MBP genotype frequencies of GGC/GAC and alleles genetic frequencies of GAC on CHB group (severe),compensation phase of LC group and decompensation phase of LC group were higher than those in the normal control group (P ＜ 0.05 ),the genetic polymorphism of decompensation of LC was 36.5 ％,highest of all.The MBP genotype frequencies of GGC/GAC and alleles genetic frequencies of GAC of patients with chronic HBV infection were not changed with the differences of HBV-DNA loads.Conclusion The codes on 54 MBP gene polymorphisms is not closely related to HBV DNA loads,but was associated with the progression of hepatitis B infection.

OBJECTIVETo elucidate the mechanism of carcinogenesis induced by coke oven emissions by investigating the cell genetic damage index and the methylation of O⁶-methylguanine-DNA methyltransferase (MGMT).

METHODSThe human bronchial epithelial cell 16HBE was treated by 1 µmol/L B(a)P for 48 h, and then was exposed continuously to either 1‰ dimethyl sulfoxide (DMSO) or organic extracts of coke oven emission (OE-COE) for five days at the concentrations of 0, 2.5, 5.0, 10.0 and 20.0 µg/ml. The methylation-specific PCR (MSP-PCR), RT-PCR and immunoblotting were applied to detect the methylation status, changes of mRNA and protein of MGMT, respectively. Single cell gel electrophoresis was used to detect DNA damage induced by OE-COE.

RESULTSCompared with the control group (DMSO), there was a significant hypermethylation in all study groups, along with the suppression of mRNA and protein in a dose-dependent manner, and the gradation ratio of them was 1.0, 0.96, 0.96, 0.85, 0.32 and 1.0, 1.0, 1.1, 0.41, 0.52, separately. There was a significant DNA damage with a dose-effect relationship in all study groups (F = 41.22, P < 0.05), and the comet Olive tail moment was (2.98 ± 1.43), (4.76 ± 1.79), (10.09 ± 1.75), (11.38 ± 1.77), (11.67 ± 1.88). The further study found that the index of DNA damage was negatively correlated to the expression of MGMT mRNA and its protein.

CONCLUSIONThe DNA damage induced by COE might be associated with the suppression of MGMT caused by its hypermethylation.

OBJECTIVETo analyze the death-related risk factors of type B aortic dissection treated medically during the acute phase (symptoms presenting within 14 d), and to determine the predictors of surgical indications for acute type B aortic dissection.

METHODSClinical data of 42 patients with acute type B aortic dissection admitted from January 2007 to May 2009 was retrospectively reviewed. There were 33 male and 9 female with a mean age of (50 +/- 12) years old. Therapy included analgesia, controlled hypotension and beta-receptor blocker, the mortality in acute phase was 33.3% (14/42). Univariate and multivariate logistic regression analyses were performed to identify the predictors of the death in acute phase.

RESULTSIn univariate logistic regression analysis, the malperfusion of aortic branches (P = 0.018) and maximum aortic diameter (P = 0.002) were significant predictors of death. In the multivariate logistic regression model, the malperfusion of aortic branches (P = 0.041) and maximum aortic diameter (P = 0.005) were also considered as the significant death-related factors.Risk of death augmented significantly (P = 0.000) when the maximum aortic diameter over 40 mm.

CONCLUSIONMalperfusion of aortic branches and the large maximum aortic diameter (> 40 mm) are the indications of surgery or endovascular therapy for acute type B aortic dissection.

Objective To investigate the risk factors related to outcome of chronic severe hepatitis B. Methods A total of 336 consecutive patients with chronic severe hepatitis B (CSHB) were analysed retrospectively. According to the outcome, objects were divided into survival group(n =137) and death group(n = 199), then to observe the differences between them in respect to age, sex, family history,prothrombin activity ( PTA ) , complications including ascites, infection, electrolyte disturbance, upper gastrointestinal bleeding, hepatic encephalopathy, hepatorenal sydrome and the corresponding quantity of complications in each individual, antivirus therapy, artificial liver support system (ALSS) therapy, and alprostadil therapy. Finally, risk factors related to prognosis were selected by stepwise Logistic regression analyse. Results In univariate analyse, significant differences between the two groups were found related to age, PTA, complications and its quantity( P ＜ 0.01 for all), and antivirus therapy ( P ＜ 0. 05 ) rather than sex, family history and treatment of ALSS or alprostadil. Logistic regression revealed that risk factors comprised of PTA and quantity of complications, antivirus therapy was the only protective factor. Conclusion A numbers of factors including age,PTA,complications and its quantity, and antivirus therapy affect the prognosis of CSHB, among which, antivirus therapy can reduce the death rate.

BACKGROUNDThis retrospective study evaluated the diagnostic accuracy of 2-(F18)-fluoro-2-deoxy-D-glucose-positron emission tomography ((18)F-FDG-PET)/computed tomography (PET/CT) in the preoperative diagnosis of metastatic mediastinal and hilar lymph node in patients with non-small-cell lung cancer (NSCLC).

METHODSA total of 39 patients received preoperative (18)F-FDG PET/CT and the postoperative biopsy. We compared preoperative PET/CT scan results with corresponding intraoperative histopathalogic findings in 39 NSCLC patients. The sensitivity, specificity, accuracy, positive and negative predictive value of (18)F-FDG PET/CT were assessed.

RESULTSHistopathologic examination confirmed metastasis in 57 out of the 208 excised lymph nodes; 23 of the 57 nodes were mediastinal and hilar lymph nodes. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of PET/CT in the preoperative diagnosis of mediastinal lymph node metastasis in NSCLC patients were 65%, 96.8%, 92%, 78.5% and 90%, respectively.

CONCLUSIONSPET/CT scan showed good accuracy in the preoperative diagnosis of mediastinal and hilar lymph node metastasis in the patients with NSCLC. We recommend that PET/CT scanning be used as a first-line evaluation tool for tumor diagnosis, therapy evaluation and follow-up.

Objective To explore the clinical factors affecting the prognosis of craniocerebral traffic injuries to provide scientific evidence for ameliorating the prognosis. Methods We retrospectively analyzed the clinical data of 652 patients treated in our hospital for serious injuries in car accidents (Glascow Coma score [GCS] 3～8) between February, 1998 and February, 2008. According to the Glasgow Outcome Scale (GOS) three months after injury, patients were divided into good prognosis and poor prognosis groups. Their gender, age, type of brain injury, admission time, pupil status, blood oxygen saturation, systolic blood pressure, level of blood sugar, Injury Severity Score (ISS) and GCS were compared. Results As compared with the good prognosis group, the poor prognosis group showed a significant low level of blood oxygen saturation and systolic blood pressure, low GCS and pupils status score (P<0.05);it showed a long admission time, a significant high level of blood sugar and high ISS (P<0.05). Bad prognosis appeared in intracranial hematoma, contusion and laceration of the brain. And the level of blood sugar and oxygen, GCS and ISS were the independent factors affected the prognosis. Conclusion The level of oxygen saturation and blood sugar, ISS and GCS can help to evaluate the prognosis of patients with severe brain injury, effectively.
