Objective:To analyze the mutation spectrum and hematological phenotype of hemoglobin subunit delta(HBD) gene among prenatal population in Xiangtan City, and to provide scientific basis for screening and diagnosis of rare and complex hemoglobinopathia.Methods:Prenatal population underwent screening and genetic testing for thalassemia at Xiangtan Maternal and Child Health Hospital from October 2022 to December 2023 were selected as the study subjects, combined with capillary electrophoresis results, further HBD gene sequencing was performed to identify specific genotypes.Results:A total of 5 371 subjects were enrolled, 22 cases of HBD gene mutations were detected, with a mutation carrier rate of 0.41% (22/5 371). Among them, 14 cases were diagnosed with δ thalassemia, 7 cases were δ abnormal hemoglobin, and 1 case was δ thalassemia combined with δ abnormal hemoglobin. There were 7 HBD mutant genotypes were included, with -77(T>C) being the most common, followed by hemoglobin (Hb) A 2-Huadu and CD34(+GGT); accounting for 68.2% (15/22), 9.1% (2/22), 9.1% (2/22). CD34(+GGT) was a newly discovered genotype, and CD7(GAG>TAG) was the first reported genotype in Chinese population. The Hb content, mean corpuscular volume, and mean corpuscular hemoglobin content were normal or nearly normal in 22 carriers of the HBD gene mutation; capillary electrophoresis demonstrated reduced Hb A 2 content in all cases. Conclusions:HBD gene mutations have been detected in the prenatal population in Xiangtan City, with -77(T>C) being the most common mutation genotype. None of the mutation carriers showed anemia.

Objective:To explore the related factors influencing the length of hospital stay(LOS) of pregnant women with heart disease (PWHD) after cesarean section.Methods:A total of 306 patients with PWHD who underwent cesarean section from January 2012 to March 2019 were collected. Among them, 203 patients had not undergone heart surgery (uncorrected group) and 103 patients who had undergone heart surgery (corrected group) during the same period. Demographic, perioperative and postoperative data were recorded. Predictors associated with postoperative LOS were determined using univariate and multivariate linear regression analysis models.Results:(1) The median LOS after cesarean section in the uncorrected group was 6 days (5-8 days). The results of univariate linear regression analysis showed that 38 parameters had significant impact on LOS ( P<0.05). The results of multivariate linear regression analysis showed that 5 parameters were independent risk factors for prolonged LOS in the uncorrected group; among them, the median LOS in uncorrected group with hypertensive disorders of pregnancy was 3 days longer than that in patients with PWHD alone [7 days (5-8 days) vs 4 days (4-5 days), β=0.195, P=0.001]; the median LOS in uncorrected group with high serum creatinine was 3 days longer than normal patients [7 days (5-13 days) vs 4 days (4-5 days), β=0.145, P=0.015]; the LOS of patients who chose general anesthesia was 2 days longer than that of patients who chose spinal anesthesia [6 days (4-8 days) vs 4 days (4-5 days), β=0.154, P=0.007]; the LOS of patients with postoperative pulmonary infection was 4 days longer than that of patients without pulmonary infection [8 days (5-15 days) vs 4 days (4-5 days), β=0.269, P<0.01]; the LOS of patients who admitted to ICU after surgery was 2 days longer than that not admitted patients [6 days (5-8 days) vs 4 days (4-5 days), β=0.268, P<0.01]. (2) The median LOS after cesarean section in corrected group was 4 days (4-5 days). The results of univariate linear regression analysis showed that 8 parameters had significant impact on the LOS (all P<0.05). The results of multivariate linear regression analysis showed that 2 parameters, which were American Society of Anesthesiologists (ASA) grade ( β=0.198, P=0.028) and intraoperative blood loss ( β=0.285, P=0.003), were the independent risk factors for prolonged LOS in corrected group. Conclusion:Preoperative with hypertensive disorders of pregnancy, preoperative creatinine increase, intraoperative general anesthesia, postoperative pulmonary infection, and postoperative admission to ICU are independent predictors of prolonged LOS in uncorrected patients with PWHD; ASA classification and intraoperative bleeding are independent predictor of prolonged postoperative LOS in patients with corrected PWHD.

Objective:To investigate the effect of situational simulation drill in nurses training on prevention and treatment of venous thromboembolism (VTE).Methods:Totally 120 nurses in 1-3 years from a tertiary general hospital were selected to participate in the training for prevention and treatment of venous thromboembolism. They were divided into intervention group and control group according to the number of single and double packet ward. A total of 62 nurses in the single wards were selected as the intervention group, and a total of 58 nurses in the double wards were selected as the control group. The control group and the intervention group were trained on the prevention and treatment of venous thromboembolism by traditional teaching method and scenario simulation drill, and the effect was evaluated by Kirkpatrick Model.Results:After training, intervention group training object theory examination score, operation assessment score, clinical nursing work assessment score, and nurses ability to scale score (83.79±6.85), (87.00±4.57), (7.90±0.62), (79.03±8.24) respectively, were higher than the control group (80.67±7.90), (84.02±4.70), (7.21±0.72), (70.86±11.59), the score comparison difference was statistically significant ( t values were -3.660-5.670, P < 0.05); The satisfaction of the training object to the teaching plan, teaching content and teaching form in the intervention group was 88.71% (55/62), 87.10% (54/62) and 87.10% (54/62), which were all higher than the control group 74.14% (43/58), 72.41% (42/58) and 68.97% (40/58), with statistically significant differences ( χ2 values were 4.250, 4.038, 5.804, P<0.05). Conclusion:The application of situational simulation drill in the nursing training of prevention and treatment of VTE is helpful to improve the theoretical skills and clinical work ability of nurses in the prevention and treatment of VTE, and to increase the satisfaction of nurses with the training.

Objective: To investigate the incidence and risk factors of postoperative acute renal injury (AKI) in patients after primary unilateral hip and knee replacement. Methods: Between January 2016 and July 2018, A total of 1 490 patients underwent hip and knee arthroplasty were enrolled. There were 507 male and 983 female with a median age of 66 years (range: 18 to 95 years). There were 201 patients underwent femoral head replacement, 897 total hip arthroplasty and 392 total knee arthroplasty, respectively. The creatinine value was 68.79 μmol/L preoperatively. Demographic, perioperative and postoperative data were recorded. The development of AKI was defined according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The demographic information, comorbidities, preoperative medication, type of surgery, type of anesthesia, intraoperative anesthetics, operation time, intravenous fluid type and dose, amount of bleeding and postoperative creatinine values were recorded. Predictors associated with AKI and postoperative creatinine was determined by multiple regressions. Results: There were 80 cases developed AKI with the incidence of AKI 5.4%. Among the AKI patients, there were 69 cases (4.6%) in AKI stage 1, 7 cases (0.5%) in AKI stage 2, and 4 cases (0.3%) in AKI stage 3. The creatinine value was 72.03 μmol/L after surgery. The length of postoperative hospital stay was 9 days. There were 5 patients died in hospital. The independent risk factors of AKI after hip and knee arthroplasty included old age, a higher American Society of Anesthesiologists (ASA) grade and preoperative diabetes (P<0.05). The risk of postoperative AKI in patients aged 60-69 years, 70-79 years, and older than 80 years was 2.259, 2.798, and 6.049 times than that of patients under 60 years of age, respectively. The risk of postoperative AKI in patients with ASA grade II, III, and IV was 3.749, 9.023, and 21.595 times than that of ASA grade I patients, respectively. The risk of AKI in patients with diabetes before surgery was 2.377 times higher than that in non-diabetics. Age, diabetes, hypertension and preoperative serum creatinine were positively correlated with postoperative creatinine values (P<0.05). Intensive care unit admissions were greater in AKI patients than that in non-AKI patients (25.0%, 5.6%, χ²=-6.774, P<0.001). Compared with non-AKI patients, the postoperative length of hospital stay was longer in AKI patients (Z=-3.904, P<0.001). Conclusion The incidence of postoperative AKI after primary hip and knee replacement was 5.4%. The older age, ASA grade, and diabetes were independently associated with risk of AKI. Old age, male, preoperative diabetes, hypertension and a higher preoperative creatinine value can predict postoperative increased creatinine levels at postoperation. The risk factors for AKI included old age, a higher ASA grade and diabetes. The postoperative length of hospital stay was longer in AKI patients.

OBJECTIVE: To characterize the traits of neuropsychological functioning deficits in patients with attention-deficit/ hyperactivity disorder (ADHD) with comorbid disruptive, impulse-control, and conduct disorders (DICCD). METHODS: Twenty out-patients with ADHD, 20 with ADHD with comorbid DICCD, and 20 with DICCD, all aged 6-16 years, were enrolled in this study, with 20 healthy subjects matched for age, gender and IQ serving as the healthy controls. The patients were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Revision (DSM-5). All the subjects were assessed with Golden Stroop test and emotional Stroop test to evaluate their response inhibition and emotional responding. RESULTS: In Golden Stroop test, the interference scores (IGs) of errors and reaction time both differed significantly among the groups ( < 0.05), and were the highest in patients with ADHD only. In emotional Stroop test, the mean reaction time (MRT) showed significant differences among the groups ( < 0.05); the MRT of positive- congruent trials in ADHD with comorbid DICCD group was shorter than that in ADHD group but longer than that in group DICCD; the MRT in the 3 case groups were all longer than that in the control group. The MRT of both positive-incongruent trials and negative-congruent trials in ADHD with comorbid DICCD group and DICCD group was shorter than that in ADHD group but longer than that in the control group. The MRT of negative- incongruent trials in DICCD group was shorter than that in ADHD group and ADHD with comorbid DICCD group but longer than that in the control group. CONCLUSIONS The response inhibition deficit and abnormal emotional responding are the core symptoms of ADHD. Bias emotional stimuli may render response inhibitory dysfunction in patients with DICCD with callous-unemotional traits of emotional responding disorder, especially in dealing with negative emotional trials, while the comorbidity of ADHD and DICCD tends to have the emotional response trait of DICCD.

OBJECTIVEThis study aimed to synthesize a novel nano-antibacterial inorganic filler that contains a quaternary ammonium salt with long chain alkyl and to report the antibacterial property of dental resin composites.

METHODSA novel nano-antibacterial inorganic filler that contains a quaternary ammonium salt with long chain alkyl was synthesized based on previous research. The antibacterial property of the filler was measured. The surface of the novel nano-antibacterial inorganic filler was modified by a coupling agent to achieve a good interfacial bonding between the filler and the resin matrix. Infrared spectrum analysis was carried out. The modified novel nano-antibacterial inorganic fillers were then incorporated into the dental resin matrix. The dispersion of the fillers was observed and compared with those incorporated into Tetric N-Ceram, a commercial resin composite, under a scanning electron microscope. Streptococcus mutans was used in testing the antibacterial property of the dental resin composites.

RESULTSA quaternary ammonium salt with a long chain alkyl was successfully grafted onto the surface of nano-silica particles. The novel nano-antibacterial inorganic filler that contains quaternary ammonium salt with a long chain alkyl showed stronger antibacterial efficacy than the antibacterial inorganic filler that contains quaternary ammonium salt with a short chain alkyl. The modified novel antibacterial inorganic fillers displayed a homogeneous dispersion in the resin composite bulk and combined closely with the resin matrix, similar to the Tetric N-Ceram. The resin composites that contain novel antibacterial inorganic fillers showed stronger antibacterial effect on Streptococcus mutans compared with the control group.

CONCLUSIONThe novel nano-antibacterial inorganic filler that contains a quaternary ammonium salt with long chain alkyl showed a strong antibacterial property. It also exhibited good compatibility with the dental resin matrix after undergoing coupling treatment.
