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 investigate the epidemiological characteristics of human adenovirus (HADV) 2, 3 and 7 in hospitalized children with respiratory infection. Methods: A total of 25 686 children with respiratory infection hospitalized at Children's Hospital of Hebei Province from January 2018 to December 2020 were retrospectively included.Deep sputum or nasopharyngeal aspirates of those children were collected. Then thirteen common respiratory pathogens were detected by multiplex PCR. 510 HADV positive specimens were randomly selected via random number and classified for type 2, 3 and 7 using a multiplex real-time quantitative PCR. SPSS 21.0 software was used to perform all of the statistical analyses. Enumeration data were expressed by frequency and percentage. χ² test was used for comparison between groups. Results: The HADV-positive rate was 7.99% (2 052/25 686). Children at age 3-<6 years had the highest HADV-positive rate (11.44%). The HADV-positive rate in 2019 was highest (10.64%). Among the 510 HADV-positive specimens, the proportion of type 3 was the highest (31.16%), followed by type 7 (21.37%) and type 2 (11.18%). The rate of type 2 in 2019 was significantly lower than that in 2018 and 2020 (χ²=8.954 and 16.354; P=0.003 and <0.01), while the rate of type 3 was significantly higher than that in 2018 and 2020 (χ²=5.248 and 4.811; P=0.022 and 0.028). The rate of type 2, type 3 and type 7 were lowest in winter, spring and autumn, respectively. The rate of type 2 increased significantly in autumn and the rate of type 3 and type 7 increased significantly in winter.The co-detection rate of HADV with other respiratory pathogens was 43.33%(221/510). Among, the co-detection rate of type 3 was highest (47.32%), and the co-detection rate of type 2, 3 and 7 was significantly higher than the alone detection rate (χ²=20.438, P<0.01; χ²=42.105, P<0.01; χ²=27.573, P<0.01).The proportion of severe pneumonia in children with type 7 positive (15.89%) was higher than that in children with non-type 7 positive (8.23%) (χ²=5.260, P=0.022). Conclusion: HADV is one of the important pathogens of children with respiratory infection in Children's Hospital of Hebei Province. The susceptible population of HADV is preschool children aged 3 to 6 years. HADV often co-detects with other respiratory pathogens. Type 3 and 7 is likely to be the dominant genotypes in this region, and type 7 may be one of the risk factors of severe pneumonia in children.

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.

XueBiJing is an intravenous five-herb injection used to treat sepsis in China.The study aimed to develop a liquid chromatography-tandem mass spectrometry(LC-MS/MS)-or liquid chromatography-ultraviolet(LC-UV)-based assay for quality evaluation of XueBiJing.Assay development involved identifying marker constituents to make the assay therapeutically relevant and building a reliable one-point cali-brator for monitoring the various analytes in parallel.Nine marker constituents from the five herbs were selected based on XueBiJing's chemical composition,pharmacokinetics,and pharmacodynamics.A selectivity test(for"similarity of response")was developed to identify and minimize interference by non-target constituents.Then,an intercept test was developed to fulfill"linearity through zero"for each analyte(absolute ratio of intercept to C response,＜2％).Using the newly developed assays,we analyzed samples from 33 batches of XueBiJing,manufactured over three years,and found small batch-to-batch variability in contents of the marker constituents(4.1％-14.8％),except for senkyunolide I(26.5％).

OBJECTIVETo explore the clinical effects of percutaneous vertebroplasty(PVP)in the treatment of osteoporotic vertebral compression fractures complicated with intravertebral clefts.

METHODSThe clinical data of 176 patients with osteoporotic vertebral compression fractures underwent treatment from January 2013 to May 2016 were retrospectively analyzed. All the patients were treated by unilateral PVP procedure, 37 patients with intravertebral clefts. Seven cases were excluded according to the standard and 30 patients were internalized in the study. There were 14 males and 16 females, aged from 60 to 93 years old with an average of (77.73±9.33) years. The mean bone mineral density was (-3.16±0.48) SD (ranged from -2.3 to -4.1 SD). The Oswestry Disability Index(ODI), visual analogue scale (VAS) were analyzed before operation and 1 day, 3 months, 1 year after operation. The compression ratio of injured vertebrae was measured by X-ray before operation and 3 days, 3 months after operation.

RESULTSAll the operations were successful and all the patients were followed up more than 1 year. Postoperative at 1 d, 3 months, 1 year, VAS scores were obviously released (2.93±0.83, 2.07±0.58, 1.57±0.68, respectively) than preoperative 7.00±1.41(<0.01);and ODI scores were obviously improved (36.2±4.1, 22.9±6.7, 18.8±5.9, respectively) than preoperative 40.5±3.9(<0.01). Postoperative at 3 days, 3 months, vertebral height percent of injured vertebrae were (79.26±8.57)% , (77.68±8.96)% , respectively, which had obviously improvement compared to preoperative (72.00±12.14)% (<0.05).

CONCLUSIONSPVP is an effective and reliable method in the treatment of osteoporotic vertebral compression fractures complicated with intravertebral clefts. It can effectively restore the height of the vertebral body, obviously improve the patient's pain and functional status.

OBJECTIVESTo research radiographic anatomy of the main structure of the pelvic Teepee view, including its azimuth direction and view anatomy structure.

METHODSFrom June 2013 to June 2014 adult pelvic CT examination results were filtered, excluding skeletal deformities and pelvic osseous destruction caused by tumors, trauma, etc. The data of 2.0 mm contiguous CT scan of 9 adults' intact pelves was,selected and input into Mimics 10.01 involving 7 males and 2 females with an average age of (41.2±10.3) years old. Utilizing the software, the 3D CT reconstructions of the pelves were completed. Setting the transparency being high,the pelvic 3D reconstructions were manipulated from the pelvic anteroposterior view to the combined obturator oblique outlet view and fine-tuned till the regular Teepee-or teardrop-shaped appearance emerges. Cutting tools of the software were at the moment applied to separate the "Teepee" from the main pelvis for each reconstruction. Then the "Teepee" and the rest (main) part of the pelvis were displayed in different color to facilitate the analysis on the Teepee, iliac-oblique, and anteroposterior views.

RESULTSThe "Teepee" started from the posterolateral aspect of the anterior inferior iliac spine and finished at the cortex between the posterior superior iliac spine and the posterior inferior iliac spine in a direction of being from caudal-anterior-lateral to cranial-posterior-medial. The radiographic anatomical composition of the "Teepee" contained one tip, one base,and two aspects. With the inner and outer iliac tables being the inner and outer aspects of the "Teepee", the tip is consequently formed by their intersection. The base is imaged from the cortex of the greater sciatic notch. The medial-inferior-posterior portion of the "Teepee" contains a small part of sacroiliac joint and its corresponding side of bone of the sacrum.

CONCLUSIONSThe "Teepee" is a zone of ample osseous structures of the pelvis, aside from a small medial-inferior-posterior portion, the main zone of which can be accepted as a safe osseous zone for the anchor of implants stabilizing certain pelvic and acetabular fracture patterns. The Teepee view can be utilized as guidance for the safe percutaneous insertion of such implants.

OBJECTIVETo introduce the location and course of S1, S2 sacral nerve root tunnel and to clarify the significance of the anterior aspect of sacral nerve root tunnel on placement of iliosacral screw on the standard lateral sacral view.

METHODSFirstly the data of 2.0 mm slice pelvic axial CT images were imported into Mimics 10.0, and the sacrum, innominate bones, and sacral nerve root tunnels were reconstructed into 3D views respectively, which were rotated to the standard lateral sacral views, pelvic outlet and inlet views. Then the location and course of the S1, S2 sacral nerve root tunnel on each view were observed.

RESULTSThe sacral nerve root tunnel started from the cranial end and anterior aspect of the vertebral canal of the same segment and ended up to the anterior sacral foramen with a direction from cranial-posterior-medial to caudal-anterior-lateral. The tunnel had a lower density than the iliac cortex and greater sciatic notch on the pelvic X-rays,especially on the standard sacral lateral view, on which it showed up as a disrupted are line and required more careful recognition.

CONCLUSIONIt can prevent the iliosacral screw from penetrating the sacral nerve root tunnel and vertebral canal when recognizing the anterior aspect of sacral nerve root tunnel and choosing it as the caudal-posterior boundary of the "safe zone" on the standard lateral sacral view.

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.

OBJECTIVESTo introduce a classification system of upper sacral segment and its significance based on the continuous pelvic axial computed tomography scan.

METHODSThe whole pelvis 2.0 mm thick axial scan images of 127 cases were observed, the sacroiliac screw channel of S1 were measured, according to the size of the transverse screw channel the upper sacral segment were classified. Such as transverse screw channel existed and in at least 4 layer scan images its width was > 7.3 mm, it was defined as sacral segment of the normal type. Such as transverse screw channel existed and its maximum width was 7.3 mm or less on scanning level, it was defined as a transitional. Such as transverse channel did not exist, or its width on all scanning level was 0 mm or less, it was defined as dysplastic. Various cases,percentage, and the average of the transverse screw channel were calculated.

RESULTSThere were 58 normal (45.7%),42 transitional (33.1%), and 27 dysplastic (21.2%) upper sacral segments with an averaged width of the tansverse screw channel of 13.9 mm, 5.2 mm, and 0.9 mm, respectively. Each specimen could be defined as one of the three types of upper sacral segment without exceptions.

CONCLUSIONIt is possible to insert a transverse iliosacral screw into a normal upper sacral segment when indicated because of the capacious transverse screw channel. The transverse iliosacral screw placement into the transitional and dysplastic upper sacral segments was contraindicated because of the limited or none transverse screw channel. The transitional upper sacral segment was superior to the dysplastic segment due to its starting point location restriction on the true lateral sacral view.
