Objective:To explore the feasibility of non-invasive prenatal testing (NIPT) for detecting fetal chromosomal copy number variants (CNV).Methods:A retrospective analysis was carried out on NIPT positive samples in Suzhou Municipal Hospital from January 1, 2019 to December 31, 2021. The effect of NIPT on fetal CNV detection was assessed by comparison with the results of karyotype analysis and/or chromosomal microarray analysis (CMA).Results:Among the 525 NIPT positive samples, 146 were CNV cases, of which 84 were further verified by karyotyping and/or CMA, 29(34.5%) were true positive. Among them, 12 cases were pathogenic variants, 2 cases were likely pathogenic variants and 15 cases were variants of uncertain significance.Conclusion:NIPT could detect CNV with high accuracy, and to combine CNV detection and chromosomal aneuploidy detection has great significance to improve the prenatal and postnatal care.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objectives:To evaluate the association between estimated pulse wave velocity(ePWV)and risk of new-onset diabetes. Methods:A total of 82 440 employees without prior diabetes who participated in the health examination from July 2006 to October 2007 were selected as the observation cohort,participants were followed-up for a mean of(13.19±3.73)years.The study population was divided into four groups according to the ePWV quartiles:group Q1(ePWV<12.35 m/s,n=20 610),group Q2(12.35 m/s≤ePWV<13.74 m/s,n=20 610),group Q3(13.74 m/s≤ePWV<15.16 m/s,n=20 611),and group Q4(ePWV≥15.16 m/s,n=20 609).ROC curve was used to analyze the predictive value of ePWV for new-onset diabetes.The incidence density of diabetes in each group was calculated.After adjustment for the traditional cardiovascular risk factors(including sex,smoking,drinking,exercise,education level,family history of cardiovascular disease,history of myocardial infarction,history of stroke,body mass index,total cholesterol,fasting blood glucose,uric acid and high-sensitivity C-reactive protein),multivariate Cox regression models were used to evaluate the association between ePWV and risk of new-onset diabetes. Results:The area under the ROC curve of ePWV was 0.60 in the prediction of new-onset diabetes,and the optimal cut-offvalue was 12.78 m/s.With the increase of ePWV quartile,the incidence density of diabetes showed an increasing trend,which was 5.84/1 000 person years,12.04/1 000 person years,15.70/1 000 person years and 16.87/1 000 person years,respectively.After adjusting for the traditional cardiovascular risk factors,the risk of new onset diabetes increased by 9%(HR=1.09,95%CI:1.08-1.11,P<0.01)for each 1 m/s increase in ePWV.Subgroup analysis showed that higher ePWV was significantly associated with increased risk of new-onset diabetes regardless of presence or absence of cardiovascular risk factors,male or female,and age<51 years or age≥51 years,with the HR(95%CI)values of 1.07(1.05-1.08)and 1.21(1.08-1.36),1.07(1.06-1.09)and 1.17(1.15-1.20),1.22(1.19-1.24)and 1.06(1.04-1.07). Conclusions:ePWV has a certain predictive value for new-onset diabetes and is an independent risk factor for new-onset diabetes.

ObjectiveTo explore the molecular mechanism of modified Shengjiangsan in alleviating endoplasmic reticulum （ER） stress and reducing urinary protein in the rat model of diabetic nephropathy （DN）. MethodSeventy-five SD rats were randomized into normal， model， low-， medium-， and high-dose （4.37， 8.73， 17.46 g·kg^-1， respectively） modified Shengjiangsan， and irbesartan （0.014 g·kg^-1） groups， with 10 rats in each group. Rats were administrated with corresponding doses of medications or distilled water by gavage， once a day， for 8 consecutive weeks. After the last administration， the levels of glucose （GLU） in the blood， 24-hour urinary protein （24 h-UTP）， and superoxide dismutase （SOD）， malondialdehyde （MDA）， and glutathione peroxidase （GSH-Px） in the renal tissue were measured. Hematoxylin-eosin staining， periodic acid-Schiff staining， and transmission electron microscopy were employed to observe the pathological changes in rat kidneys. Immunohistochemistry was employed to measure the expression levels of nephrin， podocin， glucose-regulated protein 78 （GRP78）， C/EBP homologous protein （CHOP）， and activating transcription factor 4 （ATF4） in the kidneys of rats. Western blot was employed to measure the protein levels of silent information regulator 1 （Sirt1）， phosphorylated （p）-protein kinase RNA-like endoplasmic reticulum kinase （PERK）， and p-eukaryotic translation initiation factor 2 alpha （eIF2α） in rat kidneys. ResultCompared with the normal group， the modeling caused pathological damage to the kidneys， elevated the levels of GLU and 24 h-UTP （P<0.05）， up-regulated the protein levels of GRP78， CHOP， ATF4， p-PERK， and p-eIF2α （P<0.05）， and down-regulated the protein level of Sirt1 （P<0.05） in rat kidneys. Compared with the model group， modified Shengjiangsan and irbesartan lowered the GLU and 24 h-UTP levels （P<0.05）， alleviated the pathological damage in the renal tissue， down-regulated the protein levels of GRP78， CHOP， ATF4， p-PERK， and p-eIF2α （P<0.05）， and up-regulated the protein level of Sirt1 （P<0.05）. ConclusionModified Shengjiangsan up-regulates Sirt1 expression and inhibits phosphorylation of proteins in the PERK/eIF2α pathway to reduce ER stress and oxidative stress in the renal tissue， thus alleviating the pathological damage in the renal tissue and reducing urinary protein in DN rats.

【Objective】 To evaluate the underreporting of death cases and related factors in disease surveillance system of Xi’an. 【Methods】 Multi-stage cluster random sampling was used, and 733 villages (neighborhood committees) were selected from 44 townships or streets in Xi’an. All the death cases of the residents in the sampled areas from 2018 to 2020 were collected through a variety of channels and checked with those registered in the Disease Surveillance System. Then the missing cases were investigated and verified. The underreporting rate was calculated, the Excel software was applied for statistical processing and Chi square analysis, and the related factors of underreporting were analyzed by using Logistic regression method. 【Results】 A total of 37650 death cases were investigated from 2018 to 2020; the average mortality was 650.59/10⁵, and 2 901 cases were underreported. From 2018 to 2020, the underreporting rate was 9.89%, 6.95%, and 6.24%, respectively (χ²=133.525, P<0.001), with the average underreporting rate of 7.71%. The underreporting rate in the 44 sampled areas ranged from 0.90% to 42.07%. Multivariate Logistic regression analysis showed that compared with that in rural areas (9.87%), the underreporting rate was lower in urban areas (5.91%, OR=0.567, 95% CI:0.525-0.613), and higher in children under 5 years old (31.20%, OR=5.494, 95% CI:3.732-8.090) and people aged 15-44 years old (11.85%, OR=1.541, 95% CI:1.284-1.846) compared to people over 65 years old (7.44%), and higher in 2018 (9.89%, OR=1.702, 95% CI:1.551-1.869) and 2019 (6.95%, OR=1.148, 95% CI:1.038-1.271) compared to the year 2020 (6.24%). There were 2901 cases reported missing, and the proportion of those who died at home was the highest (81.39%). Underreporting of death more easily occurred in heart diseases (36.80%) and cerebrovascular diseases (27.08%) than others. 【Conclusion】 The reporting completeness of disease surveillance system increased in Xi’an. The overall underreporting rate of death causes decreased with year from 2018 to 2020. The underreporting rates in age group under 5 years old and in rural population were still high. Therefore, the reporting and management of death information should still be strengthened to minimize the underreporting rate.

Mycoplasma capricolum subsp. capripneumoniae (Mccp) is the cause of contagious caprine pleuropneumonia (CCPP) in goats. Inactivated vaccines and capsular polysaccharide (CPS) indirect hemagglutination reagents are available for prevention and serological detection, but high culture costs and complex antigen quantification have been plagued by production staff. In order to solve these problems in production practice, a sugar fermentation medium with an initial pH value of 7.8, which could improve the production of two antigens simultaneously, was screened out by changing the initial pH value based on previous Mccp metabolomics analysis. Since phenol red can be identified by UV absorption spectrum and cetyltrimethylammonium bromide (CTAB) can bind to anionic capsular polysaccharide, a UV spectrum measurement method for analyzing the culture stage reached by Mccp and a CTAB precipitation test for relative quantification of capsular polysaccharide antigen content in the fermentation broth were established. The UV spectrum observation method can guide the production of Mccp according to the growth curve of Mccp, which greatly reduces the monitoring time of the traditional CCU method and improves the accuracy of the original eye-observation method. The established CTAB precipitation test can complete the monitoring of CPS content within 5 hours, which greatly reduces the time required compared with the traditional differential technique, and its accuracy was verified by the phenol-sulfuric acid method. The optimized culture medium and the two correlation comparison methods established in this study can effectively reduce the production cost of Mccp and improve the production efficiency. The two assays have been used in the research at our laboratory, which provides experimental data for further improvement of the production process of CCPP inactivated vaccine and capsular polysaccharide as well as rapid quantification.

Progressive encephalomyelitis with rigidity and myoclonus (PERM) is a specific subtype of the stiff-person syndrome, which is rare and difficult to diagnose clinically. A case of PERM in a 66-year-old female with a fluctuating progressive course was reported in this article. She had increased facial muscle tone, pruritus and sensory hypersensitivity mainly in the head and neck, medullary involvement syndrome and bilateral lower limb rigidity as the main clinical manifestations, and a previous history of pulmonary malignancy, thymoma, typeⅠ diabetes and Hashimoto′s thyroiditis. The patient′s serum and cerebrospinal fluid were positive for anti-glutamic acid decarboxylase antibody. The electromyogram showed a large number of motor unit potentials in the trunk and proximal extremities in the quiet state, which were significantly enhanced during spastic episodes, consistent with the electromyographic manifestations of stiff-person syndrome. The final diagnosis was PERM, and immunotherapy including gamma globulin and hormone responded well. PERM is a rare neurological autoimmune disease with atypical early symptoms, which can be easily misdiagnosed, and it requires attention to avoid delaying the diagnosis.
