ABSTRACT

Objective:To explore clinical value of nucleic acid detection for hepatitis B virus (HBV) screening in hospitalized patients.Methods:This cross-sectional study collected and analyzed plasma samples from patients admitted to 10 domestic medical institutions from July 2021 to December 2021. Serological immunoassay and nucleic acid screening were used to simultaneously detect hepatitis B markers such as hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e Antigen (HBeAg), hepatitis B e antibody (HBeAb), hepatitis B core antibody (HBcAb),and HBV DNA. Statistical analysis was performed on the serology, nucleic acid test results and clinical information of the patients.Results:Of the 8 655 collected samples, HBsAg was positive in 216 (2.50%) samples,HBV DNA was positive in 238 (2.75%) samples ( P>0.05); 210 (2.43%) samples were positive for both HBsAg and HBV DNA, 28 (0.32%) were HBsAg negative and HBV DNA positive, 6 cases (0.07%) were HBsAg positive and HBV DNA negative. Conclusion:These results indicate that the HBV DNA testing is equally effective as hepatitis B virus serological detection for hepatitis B virus screening in hospitalized patients.

ABSTRACT

Objective:This multi-centre study was conducted to assess the efficacy of various preoperative/pre-transfusion screening methods for blood transmitted disease.Methods:From July 2021 to December 2021, plasma samples of patients admitted to 10 hospitals were collected for screening preoperative/pre-transfusion blood transmitted disease. Nucleic acid detection technology was used to detect hepatitis B virus (HBV) DNA, hepatitis C virus (HCV) RNA and human immunodeficiency virus (HIV)(1+2) RNA, and the results were compared with the immuno-serological methods. χ 2 test and Kappa test were used to analyze the efficacy of these two methods. Results:A total of 8 655 valid specimens were collected from 10 hospitals. There was a statistically significant difference in the positive detection rate of HCV between the two methods ( P<0.001). There was no significant difference in the positive detection rate of HBV and HIV assessed by the two methods ( P>0.05), but the number of positive cases detected by HBV DNA and HIV RNA (218 and 4 cases) was significantly higher than the corresponding serological results (216 and 2 cases). At the same time, there were HBV, HCV and HIV immuno-serological omissions by the immuno-serological methods, among which 28 cases were HBsAg negative and HBV DNA positive, 2 cases were HCV antibody negative and HCV RNA positive, and 2 cases were HIV antigen/antibody negative and HIV RNA positive. In addition, in the 66 samples with inconsistent results from the two detection methods, 83.3% (55/66), 68.2% (45/66), 63.6% (42/66) and 62.1% (41/66) of patients aged was>45 years, tumor, surgery and male, respectively. Conclusions:Compared with immuno-serological tests, nucleic acid tests have the advantage in terms of sensitivity on detecting HBV, HCV and HIV infection and could reduce missed detection. The risk of transmission can be reduced by adding HBV, HCV, and HIV nucleic acid tests to preoperative/pre-transfusion immuno-serological tests screening for patients over 45 years of age and tumor patients.

ABSTRACT

Objective:To compare the cost-effectiveness of hospitalized Chinese patients undergoing nucleic acid screening strategies for hepatitis B and hepatitis C, immunological screening strategy, and no screening strategy under different willingness to pay (WTP). The results might aid to decision-making for the optimal strategy.Methods:In this study, nucleic acid screening, immunological screening and no screening were used as screening strategies, and China′s GDP in 2021 (80 976 yuan) was used as the threshold of WTP to construct a Markov model. After introducing parameters related to the diagnosis and treatment of hepatitis B and C in inpatients, a cohort population of 100 000 inpatients was simulated by TreeAge Pro 2021 software, the total cost, total health effects, incremental cost-effectiveness ratio and average cost-effectiveness ratio of different screening strategies were calculated, and cost-effectiveness analysis was conducted. Univariate and probabilistic sensitivity analysis were used to assess the impact of parameter uncertainty on the final results.Results:Compared with the non-screening strategy, the incremental total cost of the hepatitis B immunological screening strategy for cohort patients was 11 049 536 yuan, and the incremental cost-effectiveness ratio was 24 762 yuan/quality-adjusted life years (QALY), while the total incremental cost of nucleic acid screening was 19 208 059 yuan, and the incremental cost-effectiveness ratio was 29 873 yuan/QALY; the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 834 yuan/QALY. Compared with the non-screening strategy, the incremental cost-effectiveness ratio of hepatitis C immunological screening strategy was 5 731 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening strategy was 8 722 yuan/QALY, the incremental cost-effectiveness ratio of nucleic acid screening and immunological screening was 45 591 yuan/QALY. The results of probabilistic sensitivity analysis showed that when the cost of nucleic acid testing exceeded 214.53 yuan, it was not cost-effective to perform hepatitis B nucleic acid screening under the WTP as 1 fold GDP. When the cost of nucleic acid testing exceeded 132.18 yuan, it was not cost-effective to conduct hepatitis C screening under the WTP as 1 fold GDP.Conclusions:Nucleic acid screening strategy can achieve more cost-effectiveness and is worthy of vigorous promotion. Compared with no screening, both the nucleic acid and immunological screening strategies are cost-effective, and hepatitis nucleic acid screening is the optimal strategy for hospitalized patients.

ABSTRACT

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

ABSTRACT

Objective:To explore the selection strategy of blastocyst transfer number in freeze-thaw cycle for women over 40 years old, so as to provide reference for reducing twin rate and improving perinatal clinical outcome.Methods:A retrospective analysis was made of 377 patients who underwent freeze-thaw blastocyst transplantation in the reproductive center of Guangdong Maternal and Child Health Hospital from January 2017 to December 2019. They were divided into single blastocyst and double blastocyst transplantatio groups according to the number of blastocyst transplantation. The clinical pregnancy rate, implantation rate, abortion rate, live birth rate, premature delivery rate, twin rate and singleton delivery rate were compared between the two groups.Results:⑴There was no significant difference between two groups regarding the majority of baseline characteristics, including age at retrieval, age at transfer, body mass index (BMI), antral follicle count (AFC), basal follicle stimulating hormone (FSH), anti Mullerian hormone (AMH), endometrial thickness at transfer day, number of oocytes retrieved, Gn starting dose, Gn days, Gn dosage, embryos at cleavage stage and top-quality embryos ( P>0.05). ⑵ There was no significant difference in the rate of implantation, early pregnancy loss, late pregnancy loss and live birth between two groups ( P>0.05). ⑶ The preterm birth rate was higher in the double blastocyst transplantation group compared with the single blastocyst transplantation group, albeit not reaching significant difference (31.7% vs 12.5%, P=0.083). ⑷ The clinical pregnancy rate and the twin pregnancy rate was significantly higher in the double blastocyst transplantation group compared with the single blastocyst transplantation group ( P<0.05). ⑸ The singleton birth rate was significantly lower in the double blastocyst transplantation group compared with the single blastocyst transplantation group (75.61% vs 95.83%, P<0.05). Conclusions:In women ≥40 years old, transferring a single blastocyst can result in live birth rate that is similar as transferring two blastocysts while dramatically reducing the risk of twin pregnancy rate and increasing singleton birth rate.

ABSTRACT

Objective:To investigate the application value of high-frequency linear array probe in prenatal ultrasound diagnosis of fetal kidney fusion anomalies.Methods:A senior sonographer for prenatal diagnosis used a convex array probe and a high-frequency linear array probe to obtain and store renal images of the transverse section, sagittal and coronal plane and ectopic kidney of 27 fetuses with suspected or diagnosed fetal renal fossa emptiness, abnormal renal position and abnormal renal contour in Guangdong Women and Children Hospital from December 2018 to October 2019. The images were analyzed to judge the possibility of kidney fusions by another senior sonographer (subject 1) and a junior sonographer (subject 2) separately. Then, ROC curves were plotted and statistically analyzed based on postnatal follow-up results. The Kappa coefficient between the two subjects was calculated.Results:Areas under the two ROC curves were 0.969 and 0.756 when using a convex array probe, but 1.000 and 1.000 with a high-frequency linear array probe by two subjects separately. Subject 1 had no significant difference using two kinds of probes ( P>0.05), however, subject 2 had higher diagnostic accuracy when using high frequency linear array probes ( P<0.05). The diagnostic consistence of high-frequency linear array probe between subjects was higher than convex array probe, the Kappa coefficients were 1.000 and 0.516, respectively. Conclusions:The application of high-frequency linear array probe in prenatal diagnosis of fetal kidney fusion anomalies is feasible, and can improve the confidence and diagnostic accuracy for fetal kidney fusion anomalies.

ABSTRACT

OBJECTIVE: The aim of this study was to investigate the clinical effects of sartorius tendon transposition versus sartorius transposition during bilateral inguinal lymphadenectomy of radical vulvectomy. METHODS: A total of 58 vulvar cancer patients who had surgery from May 2007 to October 2013, in which 30 patients received sartorius transposition and 28 patients received sartorius tendon transposition. All patients were matched by age, body mass index, stage, histology, and grade. Intraoperative variables and postoperative complications, recurrence, progression-free survival (PFS), and overall survival (OS) and postoperative life quality were compared and analyzed. RESULTS: No significant differences were found at median surgical times and amounts of bleeding (p=0.316 and p=0.249, respectively), neither at the incidences of groin cellulitis and lymphocele (p=0.673 and p=0.473, respectively), but the recovery times of the inguinal wounds were shorter (p=0.026) and the incidences of wound break and chronic lymphedema were significantly decreased in the tendon transposition group (p=0.012 and p=0.022, respectively). Postoperative quality of life in tendon transposition group was significantly improved as indicated by the EORTC QLQ-C30 questionnaire. Recurrences were similar (p=0.346) and no significant differences were found at PFS and OS (p=0.990 and p=0.683, respectively). CONCLUSION: Compared to sartorius transposition, sartorius tendon transposition during inguinal lymphadenectomy led to improved patient recovery, reduced postoperative complications, and improved life quality without compromising the outcomes.
