Objective To conduct Rh blood group serological testing and third-generation sequencing(TGS)on 22 RhD variant voluntary blood donors in Chongqing and explore the phenotypic distribution and genotyping of RhD variants in Chongqing.Methods From January to August 2023,individuals who participated in blood donation in our blood center were selected as the study objects.RhD variant phenotype identification was performed using routine serological methods.Once the RhD variants were identified,tests on different antigenic epitopes of RhD were conducted using a D-screen assay kit.Furthermore,after the genomic DNA from 22 RhD variant blood samples was extracted,imbraided primers design and multi-segment amplification and splicing were used to sequence the full-length RHD gene for TGS.The RHD gene sequence was analyzed using SnapGene software.Results Among the 22 RhD variants,8 were DVI type 3(36.36%),with the main mutation of RHD-CE(3-6)-D hybrid allele.Six cases(27.27%)showed partial weak D15 type,with the main mutation of c.845G>A.There were 6 cases of Asia type Del(27.27%),with the main mutation of c.1227G>A.One case was weak D17 type with a mutation of c.340C>T and 1 case speculated to be partial D(c.491A>T,p.Asp164Val,missense mutation).Conclusion The most common RhD variant phenotype among blood donors in Chongqing is DVI type 3,and the full-length haplotype sequence of RHD variant alleles can be obtained by Pacific Bioscience single-molecule real-time sequencing(SMRT).

ObjectiveTo establish a vaginal self-sampling HPV cervical cancer screening model in Hainan Province, to analyze the application of p16 protein detection in HPV positive and non-HPV16 /18 shunt screening. MethodsFrom January 2019 to September 2022, a total of 200 women from the targeted population was randomly selected for vaginal self-sampling HPV typing test to screen cervical cancer using randomized numeric table method, followed by cervical cytology sampling for cytology p16 protein detection. Postoperative pathological examination was used as the gold standard. Multivariate logistic regression analysis was used to analyze the influencing factors of HPV positive detection rate in cervical lesions, and the nomogram model was constructed simultaneously. The receiver operating characteristic(ROC) curve and calibration curve were used for evaluating the accuracy of the nomogram model. Differences in the distribution of self-sampled HPV-positive and HPV infected genotypes were recorded, and the application of p16 protein detection in HPV-positive and non-HPV16/18 shunt screening was analyzed. ResultsAged ≥40 years, BMI ≥28.00 kg·m^-2, number of sexual partners ≥2, frequency of sexual life ≥10 times·month^-1, bleeding from sexual intercourse, and age of first sexual intercourse <22 years were the risk factors for HPV positive of cervical lesions (all P<0.001). The results of ROC curve and calibration curve showed that the area under ROC curve (AUC) was 0.874 (95%CI: 0.823‒0.907, P<0.05), the sensitivity was 0.835, the specificity was 0.847, and the Youden index was 0.672, indicating a good fit of the model. Results of vaginal self-sampling HPV test showed that the positive rate of HPV was 86.50% (173/200). HPV high-risk infection types mainly included HPV16, 18, 31, 33, 35, 39, 45, 52, 56, 58, 59, 68, 73, and 82. Single HPV infection accounted for 95.95% (166/173), 2.89% (5/173) were infected with two types of HPV, and 1.16% (2/173) were infected with three or more types of HPV. Colposcopic pathologic diagnosis was used as the gold standard, and the results showed that the accuracy of p16 protein detection in the diagnosis of cervical cancer was 93.50% (187/200), with a sensitivity of 96.53% (167/173), and a specificity of 74.07% (20/27). The negative and positive predictive value were 76.92% (20/26) and 95.98% (167/174), respectively. The results of shunt screening showed that there were 80 cases infected with HPV16, 79 cases infected with HPV18 and 41 cases of non-HPV16/18, with a sensitivity of 90.91%, 90.32% and 86.67%, a specificity of 71.43%, 64.71% and 72.73%, a negative predictive value of 62.50%, 64.71% and 66.67%, a positive predictive value of 93.75%, 90.32% and 89.66%, and an accuracy of 87.50%, 84.81% and 82.93%, respectively. The specificity and accuracy of p16 positive screening for cervical cancer were significantly higher than that of HPV positive detection, but the false positive rate was significantly lower than that of HPV positive detection. The AUCs of HPV positive, p16 positive and combination of the two detection methods for cervical cancer were 0.603, 0.822 and 0.907, respectively. ConclusionVaginal self-sampling HPV testing is a widely accepted mode for cervical cancer screening. Cervical cytology p16 protein detection is important for self-sampled HPV positive and shunt screening of non-HPV16/18.

Objective:To explore the clinical efficacy and safety analysis of a novel laser localization technology assisted percutaneous puncture of trigeminal nerve microsphere capsule compression surgery for the treatment of primary trigeminal neuralgia.Methods:A retrospective selection was conducted on 63 patients with primary trigeminal neuralgia who underwent percutaneous puncture of the trigeminal nerve microsphere capsule compression surgery at the First Hospital of Hunan University of Chinese Medicine from January 2020 to December 2021. According to different surgical methods, they were divided into a new laser localization assisted puncture group (observation group) of 32 cases and a traditional barehanded localization puncture group (control group) of 31 cases. An analysis was conducted on the surgical time, puncture time, puncture frequency, intraoperative exposure to radiation, number of cases of poor balloon formation, and clinical efficacy within 6 months after surgery for two groups of patients. The prognosis of the patients was followed up at 6 months after surgery.Results:The surgical time, puncture time, puncture frequency, and intraoperative exposure of the observation group were all less than those of the control group, and the differences were statistically significant (all P<0.05). There was no statistically significant difference ( P>0.05) in the number of cases of poor balloon angioplasty between the observation group and the control group, as well as the pain score grading of the Barlow Neurological Institute (BNI) on the first day after surgery. Within 6 months after surgery, there was no statistically significant difference in the incidence of facial numbness, diplopia, masseter weakness, perilabial herpes, and recurrent pain between the two groups of patients (all P>0.05). Conclusions:Laser positioning technology can assist in precise puncture of the foramen ovale and accurate placement of balloons based on surgical experience, which helps to improve surgical safety, reduce postoperative complications and intraoperative radiation dose, and achieve satisfactory short-term follow-up results.

OBJECTIVES: To investigate the genotypes and biochemical phenotypes of neonates with abnormal metabolism of butyrylcarnitine (C4). METHODS: One hundred and twenty neonates with increased C4 levels detected by tandem mass spectrometry in the neonatal screening at Children's Hospital, Zhejiang University School of Medicine from January 2018 to June 2023 were included. The initial screening data and recalled data of C4 and C4/C3 were collected and converted into multiples of C4 reference range. Next generation sequencing was performed and the exons with adjacent 50 bp regions of ACAD8 and ACADS genes were captured by liquid phase capture technique. Variant information was obtained by bioinformatic analysis and the pathogenicity were classified according to the American College of Medical Genetics and Genomics criteria. The Wilcoxon rank sum test was used to analyze the differences in C4 levels among neonates with different variation types. RESULTS: In total, 32 variants in ACAD8 gene were detected, of which 7 variants were reported for the first time; while 41 variants of ACADS gene were detected, of which 17 variants have not been previously reported. There were 39 cases with ACAD8 biallelic variations and 3 cases with ACAD8 monoallelic variations; 34 cases with ACADS biallelic variations and 36 cases with ACADS monoallelic variations. Furthermore, 5 cases were detected with both ACAD8 and ACADS gene variations. Inter group comparison showed that the multiples of C4 reference range in initial screening and re-examination of the ACAD8 biallelic variations and ACADS biallelic variations groups were significantly higher than those of the ACADS monoallelic variations group (all P<0.01), while the multiples in the ACAD8 biallelic variations group were significantly higher than those in the ACADS biallelic variations group (all P<0.01). The multiples of C4 reference range in the initial screening greater than 1.5 times were observed in all neonates carrying ACAD8 or ACADS biallelic variations, while only 25% (9/36) in neonates carrying ACADS monoallelic variations. CONCLUSIONS ACAD8 and/or ACADS gene variants are the main genetic causes for elevated C4 in newborns in Zhejiang region with high genotypic heterogeneity. The C4 levels of neonates with biallelic variations are significantly higher than those of neonates with monoallelic variations. The cut-off value for C4 level could be modestly elevated, which could reduce the false positive rate in tandem mass spectrometry neonatal screening.

Objective:To understand the current status of nurses' work engagement in cancer hospitals, explore its influencing factors and the mediating effect of work acceptance between hospital magnetic level and work engagement.Methods:In September 2019, 420 nurses from a ClassⅢ Grade A cancer hospital were selected as the research object by convenient sampling. The General Information Questionnaire, the Chinese version of the Essentials of Magnetism ScaleⅡ (EOMⅡ) , Work-related Acceptance and Action Questionnaire (WAAQ) and the Utrecht Work Engagement Scale (UWES) were used to conduct a cross-sectional survey of nurses. Single factor analysis, correlation analysis and structural equation model were used to analyze the relationship among hospital magnetic level, work acceptance and work engagement of nurse. A total of 420 questionnaires were distributed and 408 valid questionnaires were collected.Results:Among 408 nurses, the scores of EOM Ⅱ, WAAQ and UWES were (141.53±22.73) , (33.79±8.38) and (45.11±17.27) respectively. Work engagement was positively correlated with hospital magnetic level and work acceptance with statistical differences ( r=0.549, 0.564; P<0.01) . The hospital magnetic level had a positive predictive effect on work acceptance (β=0.39) and work engagement (β=0.40) , and work acceptance had a positive predictive effect on work engagement (β=0.47) . Work acceptance had a partial mediating effect between hospital magnetic level and work engagement, and the mediating effect accounted for 31.49% of the total effect. Conclusions:Work acceptance plays a part of the mediating role between hospital magnetic level and work engagement. Nursing managers can create a magnetic nursing work environment to promote nurses' work acceptance and increase their work engagement.

BACKGROUND: In the treatment of osteoporotic vertebral compression fractures with percutaneous vertebroplasty, the efficacy and safety of bone cement injection by unipedicular and bipedicular approaches are still controversial. Some studies suggest that bone cement injection via unipedicular approach can shorten operation time and reduce postoperative complications, while the other studies suggest that bone cement injection via bipedicular approach can make bone cement distribute more evenly in the vertebral body and relieve pain better. OBJECTIVE: To systematically assess the efficacy and safety of percutaneous vertebroplasty via unipedicular versus bipedicular approach in the treatment of osteoporotic vertebral compression fractures. METHODS: Randomized controlled trials about unipedicular versus bipedicular percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fracture published before September 18 t h, 2018 were retrieved in the PubMed, Cochrane library, Embase, CNKI, VIP, WanFang data and CBM. Two researchers independently screened all the literatures, carried out data extraction and used improved Jadad to evaluate the methodological quality of the included studies. Meta-analysis using Revam 5.3 was conducted. Egger's test was utilized to evaluate the publication bias. RESULTS AND CONCLUSION: Totally 14 randomized controlled trials including 900 cases were eventually included, 452 cases in unipedicular approach group and 448 cases in bipedicular approach group. The Meta-analysis results showed that compared with the bipedicular approach, the unipedicular approach required shorter operation time [weighted mean difference (WMD) =-16.59, 95％ confidence interval (CI) (-19.25, -13.94), P < 0.001], smaller amount of bone cement injected [WMD=-1.27, 95％ CI (-1.64, -0.89), P < 0.001], and had lower incidence of cement leakage [relative risk=0.70, 95％ CI (0.53, 0.92), P =0.01]. There were no significant differences in short-and long-term Visual Analogue Scale scores, short-and long-term Oswestry Disability Index scores, and the postoperative incidence of adjacent vertebral fractures between the two groups (P> 0.05). Overall, bone cement injection both via bipedicular and unipedicular approaches can lead to a significant improvement in pain relief and living quality of osteoporotic vertebral compression fracture patients, but bone cement injection via unipedicular approach can shorten operation time, reduce cement volume and lower the incidence of cement leakage compared with the bipedicular approach.

Objective To explore the feasibility of Narcotrend index (NTI) for digital monitoring of light sedation depth in patients undergoing short-term mechanical ventilation after pancreaticoduodenectomy. Methods A prospective randomized controlled trial was conducted. Patients with mechanical ventilation for 12-48 hours after pancreaticoduodenectomy admitted to department of critical care medicine of the First Affiliated Hospital of Wannan Medical College from January 2016 to December 2018 were enrolled. They were randomly divided into two groups, and NTI and Richmond agitation-sedation score (RASS) were used to guide light sedation treatment respectively. The implementation effect of light sedation, duration of mechanical ventilation, dosage of sedative drugs, occurrence of adverse events (accidental extubation, delirium, cardiovascular events) and stress response [cortisol, epinephrine, norepinephrine, C-reactive protein (CRP)] were compared between the two groups. Results A total of 87 patients were enrolled in this study, of whom 45 received NTI-guided sedation assessment and 42 received RASS-guided sedation assessment. There were no significant differences in gender, age, body mass index (BMI), liver function classification, operation time, blood loss, conversion to laparotomy and acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score between the two groups. During sedation treatment, the light sedation compliance rate after light sedation, 2, 4, 6 hours and cumulative compliance period number (Dt) in NTI group were higher than those in RASS group [71.1% (32/45) vs. 50.0% (21/42), 80.0% (36/45) vs. 54.8% (23/42), 88.9% (40/45) vs. 59.5% (25/42), 83.9% (642/765) vs. 62.8% (475/756), all P < 0.05]. The dosage of dexmedetomidine in NTI group was higher than that in RASS group (μg·kg-1·h-1:0.60±0.10 vs. 0.54±0.12, P < 0.01), but more patients in RASS group receiveda larger dose of propofol to maintain sedation [ratio of use of propofol: 64.3% (27/42) vs. 37.8% (17/45), dose of propofol (mg/h): 47.82±7.31 vs. 30.83±10.35, both P < 0.05]. The sedation duration and duration of mechanical ventilation in NTI group were lower than those in RASS group (hours: 15.68±2.43 vs. 17.29±2.43, 16.27±2.42 vs. 18.25±2.04, both P < 0.01). There were no significant differences in hypertension, bradycardia, accidental extubation and delirium between the two groups during sedation treatment, but the incidence of hypotension in RASS group was higher than that in NTI group [35.7% (15/42) vs. 13.3% (6/45), P < 0.05]. Compared with RASS group, epinephrine, norepinephrine and the levels of CRP at treatment of 6 hours with light sedation and 2 hours after tracheal catheter removal in NTI group were decreased [epinephrine (pg/L): 138.35±18.60 vs. 157.50±19.91, 136.24±40.40 vs. 150.46±20.22; norepinephrine (pg/L): 347.34±45.46 vs. 393.75±49.77, 340.59±50.95 vs. 376.37±49.70; CRP (μg/L): 62.26±18.78 vs. 71.31±10.32, 53.30±14.47 vs. 64.26±14.69, all P < 0.05], and cortisol level 6 hours after treatment with light sedation was lower than that of RASS group (nmol/L: 327.03±41.04 vs. 358.12±70.01, P < 0.05). Conclusion The application of NTI monitoring to guide light sedation therapy for patients with short-term mechanical ventilation after pancreaticoduodenectomy can better achieve the goal of light sedation.
