Persistent Müllerian duct syndrome (PMDS) is a rare clinically and genetically overlapping disorder caused by mutations in the anti-Müllerian hormone (AMH) gene or the anti-Müllerian hormone receptor type 2 (AMHR2) gene. Affected individuals present uterus and tubes in normally virilized males and are discovered unexpectedly during other surgeries. Since it is rare and complex, a definitive clinical diagnosis can be missed, and there are no guidelines regarding how to deal with the uterus. In the present study, exome sequencing and Sanger verification were performed for causal variants in 12 PMDS patients. Preoperative diagnoses were made by positive exome sequencing in 8 patients. Of them, 7 patients evoked on the basis of ultrasound indicating bilateral testes on the same side of the body. Twelve different AMH variants (2 frameshift/nonsense, 1 deletion, 8 missense, and 1 in-frame) in 9 patients and 6 different AMHR2 variants (5 missense and 1 splicing) in 3 patients were identified. Seven variants were classified as "pathogenic" or "likely pathogenic", and 4 of them were novel. All but two patients with AMH defects showed low serum AMH concentrations, but all patients with AMHR2 defects showed elevated AMH levels. During surgery, an abnormal vas deferens was observed in half of the patients. Eight patients underwent orchidopexy with uterine preservation. Of them, 2 patients presented complications including irreducible cryptorchidism, and 3 patients developed Müllerian remnant cysts. Three patients underwent subtotal hysterectomy. Of them, one patient had complication of injury to the vas deferens, and one had hemorrhage after operation. This is the first report of PMDS involving a large Chinese population. The present study not only expands the variation spectrum but also provides clinical experience about the management of the uterus.

The α4β2-nicotinic acetylcholine receptor (nAChR) is a ligand-gated ion channel that is distributed throughout the nervous system. It is involved in the regulation of various neurotransmitters including acetylcholine, dopamine, γ-aminobutyric acid, and norepinephrine. α4β2-nAChR plays an important role in learning, memory, cognition, attention, inflammation, and pain. A large number of studies have shown that α4β2-nAChR is an important therapeutic target for neurological diseases such as Alzheimer's disease, Parkinson's disease, epilepsy, depression, nicotine dependence, pain, etc. It is an important target in the early diagnosis and curative effect detection of neurodegenerative diseases including Alzheimer's disease. This review summarizes the role, mechanisms and related drug research advances on α4β2-nAChR ligand drugs in neurological diseases, as well as providing a theoretical basis for identifying and developing more suitable α4β2-nAChR-related compounds.

Objective: To investigate theaccuracy of artificial intelligence sleep staging model in patients with habitual snoring and obstructive sleep apnea hypopnea syndrome (OSAHS) based on single-channel EEG collected from different locations of the head. Methods: The clinical data of 114 adults with habitual snoring and OSAHS who visited to the Sleep Medicine Center of Beijing Tongren Hospital from September 2020 to March of 2021 were analyzed retrospectively, including 93 males and 21 females, aging from 20 to 64 years old. Eighty-five adults with OSAHS and 29 subjects with habitual snoring were included. Sleep staging analysis was performed on the single lead EEG signals of different locations (FP2-M1, C4-M1, F3-M2, ROG-M1, O1-M2) using the deep learning segmentation model trained by previous data. Manual scoring results were used as the gold standard to analyze the consistency rate of results and the influence of different categories of disease. Results: EEG data in 124 747 30-second epochs were taken as the testing dataset. The model accuracy of distinguishing wake/sleep was 92.3%,92.6%,93.5%,89.2% and 83.0% respectively,based on EEG channel Fp2-M1, C4-M1, F3-M2, REOG-M1 or O1-M2. The mode accuracy of distinguishing wake/REM/NREM and wake/REM/N1-2/SWS , was 84.7% and 80.1% respectively based on channel Fp2-M1, which located in forehead skin. The AHI calculated based on total sleep time derived from the model and gold standard were 13.6[4.30,42.5] and 14.2[4.8,42.7], respectively (Z=-2.477, P=0.013), and the kappa coefficient was 0.977. Conclusions: The autonomic sleep staging via a deep neural network model based on forehead single-channel EEG (Fp2-M1) has a good consistency in the identification sleep stage in a population with habitual snoring and OSAHS with different categories. The AHI calculated based on this model has high consistency with manual scoring.

Objective To investigate the relationship between serum angiotensin converting enzyme (ACE) and angiotensinogen (AGT) and gestational hypertension syndrome (HDCP) and the risk factors of HDCP. Methods A total of 135 pregnant hypertensive patients (HDCP group) and 100 normal pregnant women as control check (CK) group were selected. Serum ACE and AGT levels were measured by ELISA, and correlation analysis was performed. The age and gestational age of the two groups, pre-pregnancy body mass index (BMI), parity, number of births, family history of hypertension, family history, education, and other general information, single factor analysis of risk factors for maternal HDCP, single factor regression analysis Statistically significant factors were all used for multivariate logistic regression analysis. Results The serum ACE level in the HDCP group (90.49±47.65) μg/L was significantly higher than that in the CK group (58.72±27.58) μg/L, P<0.05, the difference was statistically significant. The serum AGT level in the HDCP group was (64.57±19.71) μg/L was higher than CK group (58.22±18.64) μg/L, P>0.05, the difference was not statistically significant; single factor analysis showed; age, BMI, hypertension, family history of diabetes, ACE level was maternal (P<0.05), while gestational age, parity, number of births, and education were no significant differences in risk factors for HDCP (P>0.05). Multivariate analysis showed: age, BMI, history of hypertension and ACE. It was a risk factor for pregnancy-induced hypertension. Conclusion ACE levels are associated with HDCP. AGT levels are not associated with HDCP. Patients with a high age, high BMI, and hypertension history have an increased risk of gestational hypertension syndrome.

Objective To investigate the relationship between angiotensin converting enzyme (ACE) and angiotensinogen (AGT) gene expression, gene polymorphism and pregnancy-induced hypertension in Qinghai. Methods A total of 210 pregnant hypertensive patients (HDCP group) and 220 normal pregnant women (CK group) were enrolled. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect AGT M235T and ACE I/ D gene polymorphism. Results The proportions of ACE gene DD, ID, and Ⅱ in CK group were 28. 15%, 47. 73%, and 24. 09%, respectively. The HDCP group was 33. 81%, 51. 90%, and 14. 29%, respectively (P < 0. 05). The frequency distribution of ACE I/ D polymorphic alleles I and D was different between HDCP group and CK group(P<0. 05). D allele frequency was higher in HDCP group than in CK group (

Objective: To explore effects of histone deacetylase inhibitor Belinostat on the immunologic function of dendritic cells (DC) and its possible mechanism. Methods: Cultured mouse bone marrow-derived DC from C57BL/6 mouse in vitro. The experiments were divided into 0, 50, 100 nmol/L Belinostat + immature DC (imDC) group, and 0, 50, 100 nmol/L Belinostat mature DC (mDC). The changes of the ultrastructure of DC were observed by transmission electron microscope (TEM). Immunophenotype and CCR7 expression rate were detected by FCM, and the migration rate was observed by chemotaxis assay. The proliferation of lymphocytes stimulated by different DC was detected by mixed lymphocyte culture reaction. The cytokines in the culture supernatant, including TNF-α, IL-12 and IL-10, were examined by ELISA. RQ-PCR was used to examine the relative expression of mRNA in RelB. Results: Successful cultured and identified the qualified imDC and mDC. Belinostat decreased the expression of CCR7 on imDC [(25.82±7.25)% vs (50.44±5.61)% and (18.71±2.00)% vs (50.44±5.61)%], meanwhile increased the rate on mDC [(71.14±1.96)% vs (64.90±1.47)%]. Chemotaxis assay showed that the migration rate of Belinostat+imDC and Belinostat+mDC group were both decreased, but the difference in imDC was not significant. T lymphocyte proliferation rate stimulated by 100 nmol/L Belinostat+imDC group was lower than imDC group in condition irritation cell∶reaction cell=1∶2 [(227.09±13.49)% vs (309.49±53.69)%]. Belinostat significantly suppressed the secretion of cytokines TNF-α, IL-12 and IL-10 (all P<0.01). The relative expression of mRNA in RelB was slightly decreased in Belinostat+imDC and Belinostat+mDC group (all P<0.05). Conclusion: Belinostat could effectly suppress DC maturation and regulate immune tolerance of DC, which may be due to the down-regulation of mRNA level of RelB in DC.
