[Objective] To investigate the molecular prevalence and genotype of human parvovirus B19(B19) among blood donors in Lanzhou, and provide data support for monitoring the positive rate of B19 DNA in local blood donors. [Methods] A total of 7 644 blood donor samples collected from January to September 2022 were randomly screened using real-time fluorescent PCR, resulting in 23 samples testing positive for B19 DNA. The characteristics of the B19 DNA reactive donors including gender, age, blood donation recruitment and promotion mode, and donation frequency were analyzed using SPSS 22.0. Additionally, the VP1 gene fragment of B19 DNA reactive samples was sequenced and an evolutionary tree was constructed by the N-J method. [Results] The results showed that the positive rate of B19 DNA in Lanzhou was 0.30%, and the positive population mainly consisted of female individuals aged 18-30 years old who were first-time blood donors; furthermore, genotype 1a was identified as predominant. [Conclusion] The positive rate of B19 DNA is low among blood donors in Lanzhou, with genotype 1a being predominant. It is recommended to periodically monitor the B19 prevalence in blood donors and enhance prevention and control measures, thus improving blood quality and safety.

ObjectiveTo investigate the facilitators and barriers of home-based exercise rehabilitation for patients with chronic kidney disease (CKD). MethodsFrom December, 2023 to March, 2024, 15 CKD patients receiving treatment at the Nephrology Department of Beijing Bo'ai Hospital and undergoing home-based rehabilitation were selected, as well as eight healthcare professionals from the same department. Semi-structured interviews were conducted, and the data were coded and analyzed using Nvivo 12.0. ResultsTwo main themes were identified. The facilitators included perceived benefits, good health literacy, potential benefits of online media, supervision by healthcare professionals and adequate social support. The barriers included severe negative emotions, adverse effects of complications, insufficient emphasis on exercise rehabilitation, lack of motivation for exercise, constraints related to time and location for exercise, and insufficient rehabilitation support. ConclusionThere are vavious and individual factors influencing home-based exercise rehabilitation for CKD patients, which need an individualized exercise rehabilitation guidance to improve the adherence to self-management.

Pulmonary hypertension （PH） is a severe and rare chronic cardiopulmonary disorder for which existing vasodilator therapies can only alleviate symptoms， rather than target or fundamentally reverse the disease. Additionally， the long-term prognosis remains poor. Recent studies have found that some novel anti-tumor drugs （NADs） can relieve PH， such as imatinib， gefitinib， sorafenib， olaparib， piperacillin， everolimus， rituximab， etc. However， some NADs can induce PH or exacerbate its symptoms， including dasatinib， lorlatinib， carfilzomib， bevacizumab， trastuzumab， nivolumab， etc. The effects of lapatinib， ruxolitinib， and bortezomib on PAH are controversial. Individualized medication should be adopted in clinical practice when using NADs for treatment， with close monitoring being essential.

OBJECTIVE: To analyze the disease patterns and acupoint selection characteristics of acupuncture for epilepsy in ancient acupuncture texts, providing references and ideas for clinical acupuncture treatment of epilepsy. METHODS: Texts from the Chinese Medical Classics (5th edition) regarding acupuncture for epilepsy are reviewed. The frequency of acupoints, meridian association, distribution, specific points, corresponding epilepsy subtypes, and needling techniques are statistically analyzed. The Apriori algorithm is used for association rule analysis, and a complex network analysis is conducted for high-frequency acupoints and their corresponding subtypes and treatments. RESULTS: A total of 205 acupuncture prescriptions are identified. Ancient texts favored differentiation-based treatments for epilepsy, primarily classified into epilepsy, wind epilepsy, and five epilepsy. Commonly used acupoints include Baihui (GV20), Jiuwei (CV15), Shenmen (HT7), Shenting (GV24), and Xinshu (BL15), with a focus on the acupoints of the governor vessel, the bladder meridian, and the conception vessel. The acupoints on the head, face are combined with the acupoints on the limbs, with skillful use of the five-shu points and intersection acupoints. The most frequent combinations are Shenmen (HT7)-Baihui (GV20), Shenting (GV24)-Baihui (GV20), and Xinshu (BL15)-Shenmen (HT7). Visual network analysis revealed that Baihui (GV20)-Shenting (GV24), Baihui (GV20)-Shenmen (HT7), and Baihui (GV20)-Zhaohai (KI6) are core acupoint combinations. Treatment mainly involved moxibustion or combined acupuncture and moxibustion. CONCLUSION The acupoint selection for epilepsy treatment in ancient texts is precise, frequently using Baihui (GV20), Jiuwei (CV15), Shenmen (HT7), Shenting (GV24), and Xinshu (BL15), etc., with emphasis on calming epilepsy, awakening the spirit, relaxing tendons, and nourishing the heart.

Objective To investigate the puncture effect of radiofrequency thermocoagulation of semilunar ganglion through the foramen ovale with ultrasound guidance and CT verification in the treatment of V3 branch trigeminal neuralgia(TN).Methods Forty-eight V3 branch TN patients,19 males and 29 females,aged＞18 years,BMI≤28 kg/m2,undergoing radiofrequency thermocoagulation of semilunar ganglion through the foramen ovale were selected.Patients were divided into two groups by random number table method:ultrasound guidance combined with CT verification group(group U)and CT guidance group(group C),24 patients in each groups.According to grouping result,patients received radiofrequency ther-mocoagulation of semilunar ganglion with foramen ovale puncture performed under the ultrasound guidance and CT verification or CT guidance respectively.The success cases of puncture,the number of puncture,ra-diation dose,puncture time,operation time and the occurrence of treatment complications were recorded.Numerical rating scale(NRS)scores and Barrow neurological institute(BNI)scores were recorded before surgery,2,4,12,and 24 weeks after surgery,and good postoperative pain relief rate(BNI Ⅰ or Ⅱ)was calculated.Results All patients in both groups completed puncture operationand radiofrequency thermo-coagulation.Compared with group C,group U had fewer number of puncture,lower radiation exposure,and shorter puncture and surgical times(P＜0.05).Compared with baseline before operation,NRS scores were significantly lower in both groups at 2,4,12,and 24 weeks after surgery(P＜0.05).There was no signif-icant difference in the rate of good pain relief 2,4,12,and 24 weeks after surgery between the two groups.There was no significant difference in the incidence of facial hematoma between the two groups.No other se-rious complications were found in both groups.Conclusion Radiofrequency thermocoagulation of semilunar ganglion through the foramen ovale with ultrasound guidance and CT verification is a safe and feasible method for the treatment of the V3 branch TN.Compared with CT guidance,ultrasound guidance combined with CT verification can significantly improve the puncture accuracy and reduce the radiation exposure related to treatment.

Objective:To explore the predictive value of red blood cell distribution width-to-platelet ratio (RPR) on arteriovenous fistula (AVF) dysfunction in maintenance hemodialysis patients with end-stage renal disease (ESRD).Methods:One hundred and five ESRD patients who underwent maintenance hemodialysis with autologous AVF in Jiangdu People′s Hospital from March 2021 to March 2023 were selected. The red blood cell distribution width (RDW) and platelet (PLT) levels were measured before the start of dialysis, and the RPR was calculated. All patients were followed up for 6 months, and AVF dysfunction was recorded and divided into dysfunction group and non dysfunction group. The levels of RDW, PLT, and RPR before dialysis were compared between the two groups. Univariate and multivariate Logistic regression analyses were used to examine the relationship between RDW, PLT, RPR and AVF dysfunction in ESRD maintenance hemodialysis patients. Receiver operating characteristic (ROC) curves were plotted to obtain the area under the curve (AUC) for RDW analysis the predictive value of PLT and RPR for AVF dysfunction in ESRD maintenance hemodialysis patients.Results:Among the 105 patients, 4 were excluded due to interruption of treatment and transfer to another hospital. Among the 101 patients ultimately enrolled, 19 patients experienced AVF dysfunction (dysfunction group), with an incidence rate of 18.81% (19/101); 80 patients did experience AVF dysfunction (non dysfunction group). C-reactive protein, RDW and RPR in the dysfunction group were higher than those in the non dysfunction group: (7.36 ± 1.92) mg/L vs. (5.90 ± 2.40) mg/L, (17.98 ± 2.40)% vs. (14.96 ± 2.29)%, 0.14 ± 0.03 vs. 0.11 ± 0.02, the proportion of diabetes patients was higher than that in the non dysfunction group, while albumin was lower than that in the non dysfunction group: (33.49 ± 2.78) g/L vs. (35.01 ± 3.02) g/L, with a statistical significant difference ( P<0.05). Multivariate Logistic regression analysis showed that C-reactive protein, RDW, RPR were all associated with AVF dysfunction in ESRD maintenance hemodialysis patients ( P<0.05). ROC curve was drawn, and the results showed that the AUC of RDW and RPR predicting AVF dysfunction in ESRD maintenance hemodialysis patients was greater than 0.7, and the AUC of RPR was higher, 0.840 (95% CI 0.752 to 0.928), with an optimal cutoff value of 0.125, specificity of 78.90%, and sensitivity of 73.20%. Conclusions:RDW and RPR are both associated with AVF dysfunction in ESRD maintenance hemodialysis patients, and may have certain predictive value for AVF dysfunction.

Objective:To explore the application of flash glucose monitoring (FGM) system in patients with type 2 diabetes and its impact on patients, and to provide reference for improving blood glucose management in patients with type 2 diabetes.Methods:Qualitative research method was adopted. Purposive sampling was used to select patients with type 2 diabetes who received FGM in Nanjing Hospital Affiliated to Nanjing Medical University, Nanjing First Hospital from December 2023 to February 2024 as interview subjects. Semi-structured interview method was conducted for one-to-one in-depth interview, and thematic analysis was used to sort out and analyze data, identify and refine themes.Results:A total of 15 interviewees were included, including 7 males and 8 females, aged (61.27 ± 14.07) years. The interview results were summarized into five themes: behavioral changes of wearing FGM system (including changes of patients′blood glucose monitoring, diet, exercise and medication behaviors); FGM system improves the convenience and comfort of blood glucose monitoring; FGM system can effectively improve patients′sense of security; the advice of medical staff affects the willingness of patients to wear FGM system; price factors affect patients′willingness to wear FGM systems on a regular basis.Conclusions:The FGM system plays an important role in the management of patients with type 2 diabetes, improving patients′self-management behavior and blood glucose monitoring experience, and improving patients′sense of security. Medical personnel play an important role in the decision-making of patient disease management. However, price is an important factor restricting patients to wear regularly, and efforts should be made to improve the popularity of FGM system.
