Objective:To explore the diagnostic value of first-trimester and mid-trimester ultrasound in screening fetal pentalogy of Cantrell, and to analyze missed and misdiagnosed cases.Methods:The fetal ultrasound image characteristics of pentalogy of Cantrell diagnosed in the Affiliated Suzhou Hospital of Nanjing Medical University from March 2018 to November 2022 were retrospectively analyzed. The necessary sections and key features of ultrasound images for diagnosing the disease in first-trimester and mid-trimester were summarized. The diagnostic value of ultrasound screenings in first-trimester and mid-trimester was analyzed, and the progression of the disease during pregnancy was understood, the missed diagnosis rate and misdiagnosis rate were calculated, and the reasons for missing diagnosis were analyzed. All fetuses were followed up to birth or induction of labor.Pentalogy of Cantrell was divided into types Ⅰ, Ⅱ, and Ⅲ according to Toyama′s research.Results:Among the 120 190 fetuses, 13 cases of pentalogy of Cantrell were diagnosed by ultrasound in first-trimester and mid-trimester. Ultrasound predominantly showed the fetal heart being malpositioned outside the chest and the fetal abdominal contents bulging outside the abdominal cavity, and the sternumal echo was partially or completely missed in some cases. All 13 cases were confirmed by follow-up, including 1 case of type Ⅱ, and 12 cases of type Ⅲ. In addition, 1 missed case of type Ⅱ pentalogy of Cantrell was followed up after birth. The correct diagnostic rates of fetal pentalogy of Cantrell using standard ultrasound sections during the first-trimester and mid-trimester were 99.9% and 100%, the sensitivity were 88.9% and 100%, the specificity were both 100%, the positive predictive values were both 100%, and the negative predictive values were 99.9% and 100%, respectively.Conclusions:First-trimester and mid-trimester ultrasound screenings have high diagnostic accuracy for pentalogy of Cantrell, and early detection and early diagnosis are of great clinical significance for the guidance of pregnancy outcomes.

Objective:To analyze the 5-year relative survival rate of cancer in Henan province based on cancer registration data.Methods:Cancer survival data were extracted from the cancer registration database of Henan province with the diagnosis date between January 1, 2010 and December 31, 2019 were included. The closing date of follow-up was set as December 31, 2019. The 5-year relative survival rate of cancer was calculated using the period survival analysis method and the Ederer II method in the R package "periodR", and the interest period was between 2015 and 2019.Results:During the period of 2015-2019, the overall 5-year relative survival rate of cancer patients in Henan province was 43.6%, and after age-standardization, it was 40.2%. The overall 5-year relative survival rate showed the characteristics of higher survival rate in females than males (45.9% vs 34.7%, Z=39.60, P＜0.001) and higher survival rate in urban areas than rural areas (44.9% vs 39.1%, Z=12.97, P＜0.001). The 5-year relative survival rate for cancer patients among children aged 0-14 was 60.2%, and for adults aged 15 and above, it was 43.5%, which was standardized to 40.2% after age adjustment. There are two types of cancers with a standardized 5-year relative survival rate exceeding 70% (thyroid cancer at 82.2% and breast cancer at 71.6%), and four cancers with a rate below 30% (pancreatic cancer at 18.2%, liver cancer at 19.6%, lung cancer at 24.0%, and gallbladder cancer at 26.6%). Conclusion:The cancer 5-year survival rate in Henan Province is lower than that of the national average, indicating the need for continued enhancement of cancer prevention and control measures.

Objective:To establish reference ranges of central nervous system-related fetal intracranial markers during the first trimester in a local population of Suzhou.Methods:Ultrasound images of fetuses with normal birth outcomes in singleton pregnancies who underwent nuchal translucency(NT) screening during the first trimester (11-13 + 6 gestational weeks) from January 2021 to July 2022 at the Affiliated Suzhou Hospital of Nanjing Medical University were retrospectively selected. The images including 3 planes: the midsagittal plane of the fetal head, also known as the plane for NT measurement, the trans-ventricular plane of the fetal head, and the axial plane of the fetal head at the posterior fossa level. The brainstem (BS) thickness, brainstem to occipital bone distance (BSOB), the ratio of BS to BSOB (BS/BSOB), intracranial translucency (IT) thickness, cisterna magna (CM) width, and the midbrain (MB) to falx (F) ratio MB/F were measured in the mid-sagittal plane of the fetal head. Choroid plexus length (CPL) to occipital frontal diameter (OFD) ratio CPL/OFD, and choroid plexus area (CPA) to head area (HA) ratio CPA/HA were measured in the trans-ventricular plane of the fetal head. Anteroposterior diameter of the fourth ventricle (4V) and CM were measured in the axial plane of the fetal head at the posterior fossa level.Statistical analysis was performed to obtain the corresponding normal reference range.Intra-class correlation coefficient (ICC) was used to analyze intra-observer and inter-observer consistency. Pearson correlation analysis and linear correlation analysis were used to study the correlations between crown-lump length (CRL) and intracranial markers, and the regression equation was derived. Results:A total of 2 331 fetuses were enrolled, providing 1 023 images of the midsagittal plane, 817 images of the trans-ventricular plane, and 567 images of the axial plane of the fetal head at the posterior fossa level. The intra-observer and inter-observer ICCs of intracranial markers BS, BSOB, BS/BSOB, IT thickness, CM width, MB/F in the mid-sagittal plane, the intracranial markers CPL/OFD, CPA/HA on the trans-ventricular plane, and the intracranial markers 4V and CM width in the axial plane at the posterior fossa level were all >0.75. Fetal intracranial markers were linearly correlated with CRL. The midsagittal plane: BS, BSOB, BS/BSOB, IT thickness, CM width, MB/F were linearly correlated with CRL ( r=0.508, 0.626, -0.234, 0.105, 0.508, -0.493; all P<0.05); the trans-ventricular plane: CPL/OFD, CPA/HA were linearly correlated with CRL( r=-0.324, -0.268; all P<0.001); the axial plane of the fetal head at the posterior fossa level: 4V, CM width were linearly correlated with CRL ( r=0.246, 0.467; all P<0.001). Conclusions:Quantitative analysis of fetal intracranial markers in the first trimester is feasible. This study constructed a normal reference range of multiple intracranial markers related to central nervous system in the first trimester with a local population of Suzhou. And the construction of this normal range can provide an objective basis for the detection of fetal central nervous system malformations in the first trimester.

Objective : To investigate the effect of high concentration of Caerulomycin A (Cae A) on HK2 in renal tubular epithelial cells and to explore the role of cytoplasmic nucleotide⁃binding oligomerization domain⁃like receptor protein 3 (NLRP3) in this process. Methods : The effect of different concentrations of Cae A on the viability of HK2 cells was determined by MTT; the expression of kidney injury molecule (KIM⁃1) and NLRP3 was detected by real⁃time quantitative PCR , Western blot and immunofluorescence , while the effect of Cae A on the mRNA expression of IL⁃1β , IL⁃18 , IL⁃33 , MCP⁃1 , TNF⁃α was also measured by real⁃time quantitative PCR. HK2 cells were divided into control group , high concentration of Cae A group and high concentration of Cae A plus NLRP3 inhibitor CY⁃09 group , and the expression of KIM⁃1 and NLRP3 protein was detected by Western blot. Results : The results of MTT showed that high concentration of Cae A could inhibit HK2 cell viability. Real⁃time quantitative PCR , Western blot and immunofluorescence assays showed that high concentration of Cae A upregulated the expression of KIM⁃1 and NLRP3 , as well as the mRNA levels of IL⁃1β , IL⁃18 , IL⁃33 , MCP⁃1 , TNF⁃α , while CY⁃09 could down⁃regulate the expression of NLRP3 and KIM⁃1. Conclusion High concentration of Cae A significantly inhibited the viability of HK2 cells and induced damage and inflammatory response to HK2 with some nephrotoxicity that might be achieved via NLRP3 pathway.

Objective:This study aims to explore the causal relationship between obstructive sleep apnea (OSA) and type 2 diabetes (T2D) using bidirectional Mendelian randomization (MR).Methods:The genetic data related to OSA were obtained from the FinnGen Biobank (Ncase=16, 761, Ncontrol=201, 194) in the Genome-wide association study (GWAS). Three single nucleotide polymorphism (SNP) were screened out as instrumental variable (IV) of OSA. The genetic data related to T2D were derived from a large Meta-analysis of GWAS (Ncase=62, 892, Ncontrol=596, 424), 114 SNP were selected as IV of T2D. Multiple MR methods were used for analysis and inverse variance weighted (IVW) was performed as main method. The sensitivity of MR analytic results was analyzed using MR-Egger and other methods, and the IV was evaluated using F-value statistics. Results:MR analysis showed that OSA was significantly associated with increased risk of T2D ( OR=2.016, 95% CI: 1.185-3.429, P<0.05). There was no significant relationship between T2D and OSA risk ( OR=1.030, 95% CI: 0.980-1.082, P=0.238). There was heterogeneity in both-way results (OSA?T2D, P=1.808×10 -11; T2D?OSA, P=1.729×10 -7), and no horizontal pleiotropy (OSA?T2D, P=0.477; T2D?OSA, P=0.349). IV of OSA and T2D-selected in the study were strong instrumental variables ( F statistics of OSA=20.543; F statistics of T2D=30.117). Conclusion:Our results supported that OSA was a risk factor for T2D, but T2D had no significant impact on the incidence of OSA. Blood glucose monitoring and diabetes screening in OSA patients might be beneficial to the early detection and intervention of T2D.

Objective:To study the correlation between the acute-phase characteristics of motor evoked potential (MEP) and severities of spinal cord injury in patients with acute cervical hyperextension injury and central cord syndrome (CCS).Methods:Retrospectively analyzed were the data of 45 patients with acute cervical hyperextension injury and CCS (observation group) who had been admitted to Department of Orthopedics, Tongji Hospital Affiliated to Tongji University from December 2018 to July 2021 and 20 healthy controls. Examination of transcranial magnetic stimulation-induced MEP was performed in patients with CCS and healthy controls using a magpro x100 magnetic stimulator, and recording was conducted in bilateral abductor pollicis brevis (APB). The characteristics of MEP waveform latency, amplitude and motor threshold were described and compared between the healthy control and observation groups; the correlations were analyzed between the MEP latency and the severity of spinal cord injury [American Spinal Injury Association (ASIA) total score and motor function of Upper Extremity Motor Subscores (UEMS)] in the observation group. According to different MEP-induced states, the patients in the observation group were divided into a resting group ( n=19), a facilitation group ( n=18), and a no-waveform group ( n=8). The severity of spinal cord injury (ASIA total score) and the functional independence of the spinal cord (SCIM-Ⅲ score) were compared among the 3 groups to analyze the correlation between the MEP-induced state and the severity of spinal cord injury (ASIA total score). Results:The observation group had a significantly longer MEP latency [(30.16±6.32) ms], a significantly smaller amplitude [(0.54±0.30) mV] and a significantly higher motor threshold [(65%±11%)] than the healthy control group (all P<0.05). The MEP latency in the observation group was significantly correlated with ASIA total score ( r=-0.730, P<0.001) and UEMS ( r=-0.740, P<0.001). The ASIA total score and SCIM-Ⅲ score were significantly different among the 3 groups ( P<0.05), and the MEP-induced state was significantly correlated with the severity of spinal cord injury (ASIA total score) ( r=0.668, P<0.001). Conclusions:In patients with acute cervical hyperextension injury and CCS, the MEP latency is prolonged, the amplitude lowered, and the motor threshold enhanced. The MEP latency is strongly correlated with the severity of spinal cord injury and upper limb motor function. The MEP-induced state is also closely related to the severity of spinal cord injury.

Objective:To explore the relationship between soft markers found in the first trimester (11-13 + 6 gestational weeks) ultrasound screening and fetal adverse pregnancy outcomes. Methods:Single pregnancy fetuses were selected from the Multicenter Clinical Study of First Trimester Screening in China during August 2017 to August 2020. The types and detection rate of soft markers during the first trimester were compared. The correlation between positive soft markers and adverse pregnancy outcomes was analyzed by binary Logistics regression.Results:A total of 16 625 fetuses with complete follow-up outcomes were included in the group. Six hundred and seven ultrasonic soft markers were detected in 556 fetuses with positive soft markers during the first trimester, and the first four most frequently occurred were increased nuchal translucency (NT) (2.08%, 345/16 625), echogenic intracardiac focus (EIF) (0.94%, 156/16 625), hypoplasia of fetal nasal bone (0.20%, 34/16 625), single umbilical artery (SUA) (0.19%, 31/16 625). Among 556 fetuses, the incidence of adverse pregnancy outcome in fetuses with two or more positive soft markers was 32.50% (13/40), which was significantly higher than fetuses with single positive soft marker (11.05%, 57/516), and the difference was statistically significant (χ 2=5.055, P<0.001). The incidence of adverse pregnancy outcome in positive soft markers fetus associated with structural abnormalities was 80.77% (21/26), which was significantly higher than fetuses with isolated positive soft marker (12.08%, 64/530), and the difference was statistically significant (χ 2=90.310, P<0.001). Binary logistic regression analysis showed choroid plexus cyst (CPC), SUA, echogenic bowel (EB), absent/reversed a-wave of ductus venosus, hypoplasia of fetal nasal bone, increased NT, and EIF were closely related to the adverse pregnancy outcomes (all P<0.05). However, there were no significant correlations between tricuspid regurgitation (TR), pyelectasis (PYE) and fetal adverse pregnancy outcomes (all P>0.05). Conclusions:The ultrasonic soft markers during the first trimester are of great significance in predicting fetal adverse pregnancy outcomes. For multiple positive soft markers or positive soft markers combined with structural abnormalities, more attention should be paid to them and comprehensive evaluation is required to be carried out.

Objective:To explore the application effect of new whole-course closed sputum specimen collection technology in intensive care unit patients.Methods:From April 2020 to January 2022, the convenient sampling was used to select 442 ICU mechanical ventilation patients admitted to 6 hospitals in Jiaxing City as the research objects. According to the order of admission time, the patients were divided into the control group ( n=221) and the experimental group ( n=221) . The control group adopted the traditional open sputum specimen collection technology, while the experimental group adopted the new whole-course closed sputum specimen collection technology. The heart rate, the incidence of hypooxygen saturation and the incidence of sputum spatter were compared between the two groups after sputum sample sampling. Results:The incidences of hypooxygen saturation and sputum spatter in the experimental group were lower than those in the control group, and the differences were statistically significant ( P<0.01) . Conclusions:The new whole-course closed sputum specimen collection technology can effectively stabilize the oxygen saturation of ICU patients in the process of sputum specimen collection, reduce the incidence of sputum spatter and promote the safety of both patients and medical staff, which is worthy of clinical promotion and application.
