Objective:To explore the clinical and genetic characteristics of a child with autosomal recessive primary microcephaly (MCPH).Methods:A case study has been carried out on a boy who had presented at the Inner Mongolia Maternity and Child Health Care Hospital for microcephaly and mental deficiency in September 2022. Prenatal ultrasound images were retrospectively analyzed, and whole exome sequencing and Sanger sequencing were carried out for his family. A literature review was also carried out using keywords such as " ASPM gene", "microcephaly", "prenatal diagnosis", "primary microcephaly", " ASPM", "MCPH5", "MCPH", "autosomal recessive microcephaly", and "prenatal diagnosis on ultrasonography" on the PubMed database, Wanfang Data and China National Knowledge until September 2023. This study was approved by Medical Ethics Committee of the Inner Mongolia Maternity and Child Health Care Hospital (Ethics No. 2021-093-1). Results:The proband had shown progressive reduction in biparietal diameter (BPD) and head circumference (HC) during the fetal period. He was found to harbor compound heterozygous variants of the ASPM gene, which included a paternally derived c. 8044C>T (p.R2682X) and a maternally derived c.8652dup (p.A2885Sfs*35). Both variants were classified as pathogenic (PVS1+ PM2_Supporting+ PP4; PVS1+ PM2_Supporting+ PM3) based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). For other fetuses in his family, prenatal ultrasound and genetic testing were all normal. Literature research has identified 11 relevant articles, which included 14 MCPH cases. All of the MCPH5 cases had shown various degrees of reduced BPD/HC on fetal imaging (100%, 15/15). Developmental delay, intellectual disability, and attention deficits were noted in all survived cases, with one case having seizures (12.5%, 1/8). Their genotypes had included homozygotes (46.2%, 6/13) and compound heterozygotes (53.8%, 7/13) for nonsense variants (45%, 9/20) and frameshifting variants (55%, 11/20). Conclusion:The compound heterozygous variants c. 8044C>T (p.R2682X) and c. 8652dup (p.A2885Sfs*35) of the ASPM gene probably underlay the reduced BPD and HC in this proband with MCPH.

Objective:To conjecture the correlation between fetal hydrothorax(FHT)and pregnancy outcome through the analysis of 95 fetuses with hydrothorax and their mothers.Methods:In this case series study, 95 FHT patients admitted to the Third Affiliated Hospital of Zhengzhou University from January 2016 to October 2022 were retrospectively analyzed.According to the pregnancy outcome, these patients were divided into the induced labor group (13 patients) and the delivery group (82 patients). General data and genetic examinations of patients in the induced labor group were analyzed to explore their pathogenesis and genetics.According to the neonatal Apgar score, patients in the delivery group were divided into the normal group and the asphyxia group.Fifteen indicators including the maternal age, gestational week at first diagnosis, maternal complications, FHT location, FHT severity, FHT outcome during pregnancy, fetal ascites, hydrops fetalis, other abnormal fetal structures, amniotic fluid volume, intrauterine treatment, gestational week of delivery, mode of delivery, sex of the newborn, and newborn birth weight in the 2 groups were comparatively analyzed by the chi-square test.With the neonatal Apgar score as the dependent variable, variables that had statistical significance during the univariate analysis were included in the regression analysis, and a multivariate binary Logistic regression equation was established to explore the factors affecting the pregnancy outcome.Results:There were significant differences in the FHT outcome during pregnancy (16/22/13 cases vs.2/18/11 cases, χ2=6.994, P=0.030), FHT severity (27/24 cases vs.9/22 cases, χ2=4.475, P=0.034), hydrops fetalis (14/37 cases vs.23/8 cases, χ2=17.012, P=0.001), amniotic fluid volume (21/30 cases vs.24/7 cases, χ2=10.228, P=0.001), intrauterine treatment (19/32 cases vs.2/29 cases, χ2=9.603, P=0.002), gestational week of delivery[(38.15±2.05) weeks vs.(34.83±3.14) weeks, t=5.748, P=0.001], and newborn birth weight[(3 325.00±637.41) g vs.(2 714.58±837.99) g, t=3.727, P=0.001]between the normal and asphyxia groups(all P<0.05). Among them, hydrops fetalis ( OR=7.070, P=0.020) and severe FHT ( OR=6.927, P=0.043) were risk factors for neonatal Apgar scores.Intrauterine treatment ( OR=0.062, P=0.027) and gestational week of delivery( OR=0.577, P=0.022) could be used as a protective factor for neonatal Apgar scores. Conclusions:Diagnosis of FHT during the early gestational weeks and multiple fetal structural abnormalities, especially hydrops fetalis, have higher probabilities of abnormal genetic examinations, and the fetal prognosis was poor.It is recommended to carry out chromosomal karyo type and microarray tests, as well as whole exome sequencing and detection of genetic syndromes(if necessary), to avoid unnecessary fetal treatment and improve the survival rate of perinatal infants after intrauterine treatment.The poor prognosis is related to hydrops fetalis and severe FHT; however, timely intrauterine treatment and prolonging pregnancy can improve the pregnancy outcome and increase the survival rate of perinatal infants.

Objective:To understand the current situation of care needs for disabled elderly people, analyze the impact of the family environment and community services on the care needs and care pathways of older people with disabilities and to formulate effective interventions.Methods:A cross-sectional survey was conducted from August 2022 to March 2023 in five tertiary-level hospitals in Tangshan city. The survey included 332 elderly people who were disabled before hospitalization and their primary caregivers, who were selected using a convenience sampling method. The survey investigated their general information, degree of disability, family members′ support, children′s filial piety and old age ethical level, family relationships, and the care needs of the elderly people who were disabled. SPSS 22.0 was used for one-way and correlation analyses as well as multiple linear regression analyses, and AMOS 22.0 was used for the development of structural equations for path analysis.Results:Among 332 disabled elderly individuals, there were 166 males and 166 females each. The care needs score for elderly people with disabilities was 101.54 ± 16.38. The care needs of this population can be influenced by several factors, including the level of disability, number of chronic conditions, presence of chronic pain, filial piety and old age ethical level of caregivers, family relationships, and the availability of care services in the community or village. These factors had direct effects of 0.468, 0.155, -0.083, -0.350, -0.094, and 0.104, respectively.Chronic diseases and chronic pain indirectly affected the demand for care through the degree of incapacity (with respective indirect effect values of 0.065 and 0.049). Additionally, the demand for care was indirectly influenced by the level of filial piety and ethics of the caregiver through the degree of incapacity and the family relationships (an indirect effect value of -0.162).Conclusions:The care needs of the disabled elderly are high, and the personal physiology, family environment and community support of the disabled elderly will directly or indirectly affect their care needs. Therefore, many factors should be considered comprehensively considered to improve the quality of care of the disabled elderly.

【Objective】 To evaluate the HBsAg detection results of HBsAg+ samples after 8 years refrigeration by ELISA and evaluate the effectiveness of the current storage policy of retained samples. 【Methods】 A total of 100 HBsAg+ plasma samples by ELISA from May 2014 to March 2015 and refrigerated at -20℃ were collected and retested for HBsAg using the same method after thawing in 2023. 【Results】 The HBsAg retest results of 100 plasma samples were all positive, with the concordance rate of 100%, though there was a significant decrease in the S/CO value after refrigeration(27.52 vs 19.03, P<0.05). 【Conclusion】 Long-term refrigeration can lead to a decrease in the S/CO value of HBsAg ELISA detection,but it does not affect the positive results.

Objective To analyse the prognosis and risk factors of lung cancer with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Tongchuan City, and to provide a theoretical basis for improving the prognosis of patients with lung cancer complicated with AECOPD. Methods A total of 280 patients with lung cancer combined with AECOPD admitted to Tongchuan People's Hospital from January 2021 to August 2022 were selected and divided into survival group and death group according to whether the patients survived during hospitalization. Serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA 21-1) and other tumor markers were compared between the two groups. Lung function was measured by lung function instruments, and the levels of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC and other lung function indicators were compared between the two groups. The patients' clinical data were collected from the medical record system, and univariate analysis and logistic regression were used to analyze the independent risk factors affecting the prognosis of patients with lung cancer complicated with AECOP. Results The values of FEV1, FVC and FEV1/FVC in the death group were significantly lower than those in the survival group (P<0.05). Serum CEA and CYFRA 21-1 levels in the death group were significantly higher than those in the survival group (P<0.05). Multiple logistic regression analysis showed that albumin level <35 g/L (OR=2.728), TNM stage III to IV (OR=2.416), multidrug-resistant bacterial infection (OR=2.982), and GOLD grade III to IV (OR=3.417) were independent risk factors for death in patients with lung cancer complicated with AECOPD in Tongchuan City (P<0.05). Conclusion Patients with lung cancer complicated with AECOPD in Tongchuan City have a high risk of death during hospitalization, especially patients with TNM stage III to IV and GOLD grade III to IV. Multi-drug resistant bacteria infection should be actively controlled to improve the albumin level of patients, which is conducive to the prognosis of patients.

BACKGROUND:Vibration environment can cause spinal injury,especially in patients with scoliosis.At present,there is no information about the inherent mode of the whole spine from T1 to the pelvis in scoliosis patients in the free state. OBJECTIVE:To analyze the dynamic characteristics of the whole spine in patients with scoliosis by the finite element method. METHODS:Based on CT scan images,a three-dimensional finite element model of the T1-pelvic total spine of an 11-year-old patient with thoracolumbar biflexion scoliosis was established,and the Cobb angles of thoracolumbar scoliosis were 36° and 24°,respectively.The mode analysis in the free state of the whole spine was carried out by the finite element method. RESULTS AND CONCLUSION:The fifteen-order free modes of the spine were extracted,and the dynamic characteristics of the scolio-curved spine were obtained.The resonance frequency distribution of the spine was concentrated.The thoracic vertebra was the most deformed in the whole spine model,and the amplitude of the thoracic vertebra was larger than that of the lumbar vertebra.Modal analysis was used to analyze the vibration characteristics of scoliosis patients in the vibration environment.It is of great significance to determine the natural frequency,vibration mode,and amplitude of scoliosis patients for analyzing the vibration characteristics of scoliosis.

Objective:To analyze the body composition and influencing factors of lean non-alcoholic fatty liver disease in population receiving health examination.Methods:This is a cross-sectional study. Between January 2020 and December 2021, 1 342 individuals who had complete and reliable results of liver transient elastography and body composition testing, with a body mass index (BMI)<24 kg/m 2 and who met the inclusion criteria, were selected from the physical examination population at the Health Management Center of Jiangsu Provincial People′s Hospital. The results of body composition analysis, blood biochemical indexes and liver examination were collected from the subjects for analysis. Method of inter-group comparison: quantitative data that conform to normal distribution were tested using independent sample t-test, while non-conforming data were tested using rank sum test; count data were tested using chi-square test. The binary logistic regression analysis was used to analyze the influencing factors of body composition in lean non-alcoholic fatty liver disease in health examinees. Results:The detection rate of non-alcoholic fatty liver disease was 13.3% in all participants, and it was significantly higher in men than that in women (23.3% (125/537) vs 6.6% (53/805)). The fasting blood glucose (5.15, 5.08 mmol/L), hemoglobin A1c (HbA 1c)(5.5%, 5.6%), triglyceride (TG)(1.70, 1.64 mmol/L), low density lipoprotein cholesterol (LDL-C)(3.37, 3.27 mmol/L), alanine aminotransferase (ALT)(27.0, 21.9 U/L), aspartate aminotransferase (AST)(24.1, 24.0 U/L), gamma-glutamyltransferase (31.4, 21.1 U/L), uric acid (UA)(391, 296 μmol/L), body fat percentage (23.9%, 33.7%), waist-to-hip ratio(0.90, 0.89) and visceral fat area (70.3, 97.0 cm 2) in men and women with lean nonalcoholic fatty liver disease were all higher than those in the population without fatty liver, while the density lipoprotein cholesterol (1.25, 1.32 mmol/L) was lower. Logistic regression analysis showed that BMI, HbA 1c, TG, UA and waist-to-hip ratio were risk factors for lean nonalcoholic fatty liver disease in men, while BMI, HbA 1c, TG, UA and body fat percentage were risk factors for lean nonalcoholic fatty liver disease in women (all P<0.05). Conclusion:BMI, HbA 1c, TG, UA, body fat percentage and waist-to-hip ratio are associated with the development of lean nonalcoholic fatty liver disease.

Objective:To evaluate the arousal effect of plantar reflex area and acupoint massage combined with music therapy in patients with brain trauma and coma.Methods:From March 2022 to March 2023, 90 patients with brain trauma and coma who were treated in the Neurosurgery Intensive Care Unit of Tangshan Gongren Hospital in Hebei Province were selected as the research subject. According to the random number table method, patients were divided into a control group, experimental group 1, and experimental group 2, with 30 cases in each group. The control group received routine nursing for brain trauma, while the experimental group 1 received music therapy with the natural voice on the basis of the control group. The experimental group 2 was treated with plantar reflex area and acupoint massage treatment on the basis of the experimental group 1. This study compared the Glasgow Coma Scale (GCS) scores and Coma Recovery Scale-Revised (CRS-R) scores of three groups of patients before and after intervention.Results:After 2, 4, and 6 weeks of intervention, the GCS scores and CRS-R scores of patients in experimental group 2 were higher than those in the control group and experimental group 1, with statistically significant differences ( P<0.05) . Conclusions:The combination of plantar reflex area and acupoint massage with music therapy has a certain arousal effect on patients with brain trauma and coma, and can be promoted and applied in clinical practice.

Compared with the global situation,it can be found that the cancer incidence in China is close to the world average level,but the mortality rate has difference compared with the global average level.The burden of gynecological cancers in China is increasing,with large differences between urban and rural areas and uneven regional distribution.Therefore,the situation of cancer prevention and control is still challenging.In recent years,new technologies and drugs,such as immune checkpoint inhibitors(ICIs)and antibody-drug conjugate(ADC),have been introduced into clinical practice,bringing new hope for the treatment of gynecological cancers.This article reviewed the major research progress of gynecological cancers in 2023.Among them,in terms of the progress of treatment for cervical cancer,we reviewed the innovation of standard treatment mode and the related progress of post-line treatment for advanced recurrent and metastatic cervical cancer(clinical research such as ENGOT-cx11/GOG-3047/KEYNOTE-A18,KEYNOTE-826).In terms of treatment for ovarian cancer,this review summarized the latest progress of PARP inhibitors,immunotherapy,first-line treatment of newly diagnosed ovarian cancer and treatment of recurrent ovarian cancer(FLAMES,ANITA/ENGOT-Ov41/GEICO 69-O,NRG-GY004,etc.).In terms of treatment for endometrial cancer,this study reviewed the progress in the treatment of locally advanced endometrial cancer(GOG 258,Lunchbox clinical research,etc.)and advanced/recurrent metastatic endometrial cancer(ENGOT-EN6-NSGO/GOG-3031/RUBY research,etc.),and summarized the exploration of back-line targeted immunotherapy(such as KEYNOTE-775,ADAGIO and other clinical studies).This study combed the progress of gynecological tumors in 2023 from the above aspects,aiming at providing reference for clinical practice and clinical research.

Objective To explore the predicting value of quantitative CT features of peritumoral nodules for the risk of thymic epi-thelial tumors(TETs).Methods A total of 108 patients with TETs confirmed by pathology were analyzed retrospectively.Accord-ing to the WHO classification of thymic tumors,the patients were divided into high-risk group and low-risk group.The quantitative CT features included the long diameter,volume,mass,and distance between peritumoral nodules and main tumor.The values of these features were assessed using the Mann-Whitney U test,and the thresholds were determined using the receiver operating characteristic(ROC)curve.Results Among 108 TETs patients,there were 45 patients with peritumoral nodules on chest CT,including 30 high-risk group and 15 low-risk group,respectively.Interobserver consistencies were well with intraclass correlation coefficient(ICC)between 0.886 and 0.907.The long diameter,volume,and mass of peritumoral nodules were greater in the high-risk group than in the low-risk group(P＜0.05),and there was no significant difference in the distance to the main tumor(P＞0.05).The mass of peritumoral nodules had the best diagnostic performance in predicting TETs risk,and the thresholds was 27.84 mg with the area under the curve(AUC)of 0.889,sensitivity of 83.3％,specificity of 87.5％,and accuracy of 85.3％,respectively.Conclusion The quantitative CT features of peritumoral nodules especially mass can be useful in predicting the risk of TETs.
