Objective To evaluate the copy number variation of FCGR3B gene in Henan Han systemic lupus erythematosus (SLE) patients and healthy controls,and explore the association between FCGR3B gene copy number variants (CNVs) and lupus nephritis (LN) susceptibility in Henan Han population.Methods FCGR3B CNVs was investigated in 142 SLE patients with nephritis,187 SLE patients without nephritis and 328 healthy controls.A modified methodology based on competitive PCR named Multiplex AccuCopyTM Kit was used to detect FCGR3B copy number.Clinical and laboratory data were collected retrospectively from the medical record.Logistic regression analysis was used to determine the association of FCGR3B copy number variants with LN susceptibility.Rank correlation was used to determine the correlations between FCGE3B copy number variants and clinical phenotypes of LN.Results No significant difference was detected in the copy number variations of FCGR3B in different groups.Low copy number of FCGR3B was more commonly seen in patients with nephritis (P=0.042),and was a risk factor for LN (OR=2.059; 95％ CI:1.081-3.921; P=0.028).However,high copy number (＞ 2) had no effect on SLE patients without nephritis(OR=1.152; 95％CI:0.711-1.866; P=0.565) and LN patients (OR=0.838; 95％ CI:0.529-1.329; P=0.454).There were no associations between FCGR3B copy number variants and clinical phenotypes and immunologic characteristics of LN.Conclusion The low copy number of FCGR3B is a risk factor for LN in Henan Han population.

Objective To investigate the efficacy and safety of transthoracic minimally invasive occlusion operation guided by transesophageal echocardiography for the treatment of congenital atrial or/and ventricular septal defects (ASD/VSD).Methods The clinical data of a total of 44 patients who underwent surgical occlusion operation from September 2013 to June 2015 were summarized.The whole course of occlusion procedure were dynamically monitored and guided by transesophageal echocardiography.All the patients were followed up regularly by electrocardiogram and echocardiograph.Results Among the 44 patients,43 patients(28 VSDs and 16 ASDs,including one patient suffered with VSD and ASD simultaneously)were occluded successfully,and the other patient with VSD who failed in the surgery was converted to open heart repair.The occlusion operations were finished within 22 to 48 min.The length of incision spaned from 2 to 4.5 cm.The ventilator was used for 1 to 5 hours.The total drainge volumes were recorded each patient from 0 to 50 mL.The postoperative hospitalization stay was 2 to 6 days,and all patients survived and were discharged.During the follow-up of 1 to 12 months, there was no cases with A-V conduction block,valve incompetent,cardiac arrhythmia and residual shunt of heart septel defect.Conclusion Transthoraic mini-invasive surgical occlusion of atrial and ventricular septal defects is a therapeutic method with less trauma,higher safety and feasiblity,faster recovery,and the short-term therapeutic effect is satisfying.

Objective To study the effects of sleep inertia (SI) of different time course sleeps on sleep stages and cognitions in healthy men after 30 h sleep deprivation,and also to investigate the mechanism of cognitive functions impairment in sleep inertia stages and the influential factors of sleep inertia.Methods Ten healthy men (age,(20.8 ±2.1) years) participated in the program.The program was divided into 2 stages.First,participants attended a series of tests after 20 min nap(20 min nap group)after 30 h sleep deprivation.The testing series included 3 parts:the continuous performance task,the Stroop Tests,and the Addition Tests.The series of tests were done 3 times immediately after the volunteers were awoken and each lasted about 15 minutes with an interval of 10 minutes between each test.The polysomnogram (PSG) was recorded during the nap.The following 7 days was set as washing-out period to ensure a complete recovery.Participants repeated the similar processes with 2 h nap(2 h nap group) instead of 20 min nap.The cognitive performance of each group was compared with each other along with the best cognitive performance in awakening to estimate whether or not the cognitive abilities regained the normal condition.Results ( 1 ) Sleep latency became shortened in both groups after 30 h sleep deprivation.There were no slow wave sleep (SWS) and rapid eye movement sleep (REM) sleep stages in the 20 min naps,while the percentage of SWS was increased and percentage of REM declined in 2 h naps.(2)In the early of SI (5 min after awaking),cognitive tasks showed that the abilities of continuous attention,selected attention and addition ability were all impaired (continuous performance task:(371.8 ± 21.3 ) times/3 min vs (334.4 ± 22.4) times/3 min,( 373.2 ± 19.0) times/3 min vs ( 323.7 ± 23.8) times/3 min,t =10.443,7.774,both P＜0.01; Stroop tests:(20.3 ±1.5) points vs(17.3 ± 1.0) points,(21.5 ±0.8)points vs( 16.1 ± 1.4 ) points,t =8.478,4.934,both P ＜ 0.05 ; Addition Tests:( 222.2 ± 13.2 ) s vs ( 266.6 ±23.7 ) s,( 226.3 ± 10.9) s vs ( 267.6 ± 23.4 ) s,t =5.748,6.685,both P ＜ 0.01 ).The cognitive functions impairments of 2 h nap group were more severe at the initiation of sleep inertia,but regained the normal condition more quickly.Different cognitive tasks recovered at different speeds.The dispersion of SI needed 30 min.Conclusions ( 1 ) There are difference in the sleep construction and awaked sleep stage between 20 min nap and 2 h nap groups.(2) SI exerts negative influences on cognitive performances of continuous attention,selected attention and addition after sleep deprivation.Many factors may influence the dispersion of SI,including sleep debt,compensation of sleep debt and others.(3) Fragments of sleep are unfavorable to the recovery of body.

Objective To understand the cognitive level of urban and rural general practitioners in the concept, diagnosis and treatment of chronic obstructive pulmonary disease and to provide the basis for continuing medical education in basic level hospital for all general practitioners. Methods General practitioners from 21 urban community health service centers (group A) and 27 of the rural community health service centers (group B) were surveyed on chronic obstructive pulmonary disease knowledge through a anonymous questionnaire, the survey contents included five aspects of chronic obstructive pulmonary disease such as basic concept, diagnosis, grouping diagnosis, treatment on stable phase and acute exacerbation. Results The correct rates of five questions in group A were 25.89%, 17.26%, 5.58%, 4.06%, 18.78 and in group B were 8.97%, 8.55%, 5.13%, 4.27%, 17.52%. In chronic obstructive pulmonary disease concept and diagnosis, there was significant difference between two groups(χ2=21.99, P<0.05 and χ2=7.41, P<0.05) . Conclusion The level of the cognitive of COPD (chronic obstructive pulmonary disease) among the general practitioners is very poor, and is strong against to the management work of chronic obstructive pulmonary disease. We need more continuing medical ed-ucation on "the guidelines on diagnosis and treatment of chronic obstructive pulmonary disease " among the urban and rural general practitioners.

Objective:To investigate the clinical features, diagnosis and treatment of oblique vaginal septum syndrome (OVSS).Methods:The clinical data of 80 patients with OVSS admitted to The Second Hospital of Hebei Medical University from July 2005 to July 2023 were retrospectively analyzed. According to the classification system of OVSS proposed by Female Genital Anomalies Study Group, Chinese Obstetricians and Gynecologists Association in 2021, the patients were divided into four groups. The clinical manifestations, accompanied urinary system abnormalities, diagnosis and treatment methods and treatment outcomes were observed.Results:According to the above classification system, among the 80 patients with OVSS, 35 patients (44%, 35/80) were categorized as type Ⅰ, 33 patients (41%, 33/80) were categorized as type Ⅱ, 2 patients (3%, 2/80) were categorized as type Ⅲ and 10 patients (13%, 10/80) were categorized as type Ⅳ. The main onset symptom of patients was periodic abdominal pain (70%, 56/80), vaginal bleeding (20%, 16/80), dysuria or fecal impaction (15%, 12/80), vaginal mucopurulent discharge (10%, 8/80). The morbidity of combined urinary system abnormalities was 88% (70/80), and the most common urinary system abnormality was ipsilateral renal agenesis (81%, 65/80). Bilateral kidneys were normal in 13% (10/80) patients, and 6% (5/80) were combined with other urinary system abnormalities. A total of 74 patients underwent vaginal oblique septectomy or septum excision. Five of the 10 patients with type Ⅳ underwent hysterectomy on the cervical atresia side, 4 patients received hysteroscopy combined with cervicoplasty+oblique septotomy or septum excision, and one patient selected delayed menstruation. Two patients underwent laparoscopic resection of the dysplasia kidney and ectopic ureter which opening to the vagina. Eleven patients with endometriosis cyst, hydrosalpinx or empyema underwent laparoscopic surgery.Conclusions:The main symptom of type Ⅰ and Ⅳ patients is abdominal pain, while the main symptom of type Ⅱ and Ⅲ patients is bleeding. Magnetic resonance imaging (MRI) has advantages in the evaluation of complex OVSS, and MRI is recommended before operation to exclude other axial reproductive tract dysplasia and complex urinary system dysplasia. If there is leakage of urine, vaginal discharge or complex deformity, it is necessary to multidisciplinary discussion and formulate a reasonable surgical plan. The first treatment is related to the prognosis of patients especially children, and should be highly valued.

Objective:To find clues potentially valuable for fighting against infection with human respiratory syncytial virus (HRSV), the differentially expressed genes in HEp-2 cells infected with HRSV were analyzed.Methods:Gene expression profiles of HEp-2 cells infected with HRSV were collected from the public gene expression omnibus (GEO) database. The differentially expressed genes following HRSV infection at each time point of 4, 8, 12, and 15 hours were found using R language. The differentially expressed genes were analyzed by gene ontology (GO), KEGG pathway and protein-protein interaction network (PPI). Genes with relatively high protein interaction in PPI were randomly selected for quantitative reverse transcription-polymerase chain reaction (qRT-PCR) verification at the transcription level from HEp-2 cells after HRSV infection at 4 hours.Results:A total of 101 differentially expressed genes were determined, including 92 upregulated genes and 9 downregulated genes. Function enrichment analysis revealed that HRSV infection could cause significant changes in multiple signaling pathways such as immune response in HEp-2 cells. The results of qRT-PCR were consistent with the trend of transcriptome data.Conclusions:The differentially expressed genes and the change of signaling pathways in HRSV-infected HEp-2 cells is of great significance to the studies on pathogenic mechanism and prevention of HRSV infection.
