ObjectiveThis paper aims to investigate the effect of Huangqi Guizhi Wuwu Tang combined with low-molecular-weight heparin sodium on preventing deep vein thrombosis of the lower extremities in parturients undergoing cesarean section. MethodsA total of 781 parturients who underwent cesarean section （from June 2022 to October 2025） were included in the study and randomly divided into a control group and an observation group using a random number table method. Two cases were lost to follow-up in this study. The parturients undergoing cesarean section in the control group （389 cases） received low-molecular-weight heparin sodium and a traditional Chinese medicine placebo （similar in color to the traditional Chinese medicine in the observation group）. The parturients in the observation group （390 cases） were treated with Huangqi Guizhi Wuwu Tang in addition to the intervention of the control group. The incidence of deep vein thrombosis of the lower extremities in parturients from both groups undergoing cesarean section， the numerical rating scale （NRS） pain scores on the first day， third day， and seventh day after cesarean section， the venous blood flow velocity in the lower extremities of parturients before and after treatment （popliteal vein， femoral vein）， the venous clinical severity score （VCSS） of parturients in the two groups after treatment， the coagulation function indicators before and after treatment ［prothrombin time（PT），activated partial thromboplastin time （APTT），fibrinogen（FIB），D-Dimer］， hemorheological indicators ［high shear viscosity（HSV），low shear viscosity（LSV），erythrocyte sedimentation rate（ESR）］， and the incidence of adverse reactions were compared. ResultsThe incidence of deep venous thrombosis in the lower extremities of parturients after cesarean section in the observation group （0.77%） was lower than that in the control group （2.83%） （χ²=4.862， P=0.031）. On the first， third， and seventh days after cesarean section， the NRS scores of the parturients in the observation group were lower than those of the control group （t=69.509， 23.266， 90.979； P<0.05 for all）. Before treatment， the venous blood flow velocities （popliteal vein， femoral vein） of the lower extremities in the parturients from the two groups were compared， and no statistical difference was found. After treatment， the venous blood flow velocities （popliteal vein， femoral vein） of the lower extremities in the parturients from these two groups increased， with higher indicator levels among the parturients in the observation group than those in the control group （t=40.492， 21.587； P<0.05 for all）. After treatment， the scores of each item in the VCSS of parturients were lower in the observation group than those in the control group （t=46.234， 37.786， 69.016， 39.464； P<0.05 for all）. Before treatment， coagulation function indicators （PT， APTT， FIB， and D-Dimer） of the parturients from the two groups were compared， and there was no statistical significance in the differences . After treatment， PT and APTT increased（P<0.05）， while FIB and D-Dimer decreased in the parturients from both groups（P<0.05）. The degrees of increase and decrease of all indicators were greater among parturients in the observation group than those in the control group （t=18.916， 12.522， 24.787， 27.635； P<0.05 for all）. Before treatment， the hemorheology indicators （HSV， LSV， ESR） in the parturients from both groups were compared， and there was no statistical significance in the differences. After treatment， these indicators in the parturients from both groups decreased， with lower indicator levels in the observation group than those in the control group （t=85.734， 26.280， 56.792； P<0.05 for all）. The incidence of adverse reactions of parturients after cesarean section in the observation group （3.85%） compared with that in the control group （3.34%）， and there was no statistically significant difference （χ²=0.143， P=0.705）. ConclusionHuangqi Guizhi Wuwu Tang combined with low-molecular-weight heparin sodium demonstrates a favorable preventive effect on deep vein thrombosis of the lower extremities in parturients undergoing cesarean section. This combined regimen improves lower extremity function， alleviates postoperative pain after cesarean section， and enhances lower-extremity blood perfusion in parturients， with safety and reliability.

Objective:To analyze the genetic variant characteristics of primary immunodeficiency diseases (PID) in families from Henan Province.Methods:This study conducted a retrospective analysis of 19 PID pedigrees referred to the Prenatal Diagnosis Center at Henan Provincial People's Hospital between January 2016 and March 2024. Among the 19 families, 13 underwent prenatal diagnosis at our hospital, while the remaining six received genetic counseling based on third-party genetic testing reports (confirmed by our institution's laboratory). The clinical data from these families were analyzed, and descriptive statistical analysis was applied to the data.Results:Among the 19 PID families, there were seven cases of combined immunodeficiency, three immunodeficiency syndromes, three phagocyte deficiencies, three antibody-dominant immunodeficiencies, and three immunodysregulatory disorders, involving a total of 12 genes ( IL2RG, ADA, RAG2, STAT3, SMARCAL1, ATM, POLA1, CYBB, BTK, RAB27A, LRBA, IL10R). A total of 25 genetic variants were identified, including 11 novel variants not previously documented in the ClinVar and HGMD professional databases. The novel variants comprised: IL2RG gene mutations (Exon5_8del and c.903_904delinsCT leading to p.E302*), ADA gene mutation (c.884A>G resulting in p.D295G), RAG2 gene mutation (c.513dupA causing p.W172Mfs3), POLA1 gene mutation (c.25+5G>C), CYBB gene mutations (c.824G>A/p.G275D and c.472A>T/p.K158), BTK gene mutations (c.522_523insC/p.A175fs and c.142-2A>C), and RAB27A gene mutations (c.121delA/p.T41fs and c.272delA/p.D91fs). Among the 13 families undergoing prenatal diagnosis, genetic testing revealed that 11 fetuses carried wild-type genes, and these families elected to continue their pregnancies. One fetus exhibited identical genetic variants to the proband and received a clinical diagnosis consistent with the genetic disorder, while another fetus demonstrated chromosomal copy number variations. In both of these latter cases, the families opted for pregnancy termination. Conclusion:This study identified 11 unreported variants across seven genes, highlighting the need for further expansion of PID genetic variant databases.

Objective:To analyze inpatients preferences for an unaccompanied ward and its influencing factors, for references for the implementation of unaccompanied ward management.Methods:Based on a convergent mixed research design, a convenience sampling method was used to select inpatients who visited a tertiary hospital from June to August 2024 as the survey subjects. A questionnaire survey was conducted on their willingness to choose the unaccompanied ward (provided by medical nursing staff). Meanwhile, using purposive sampling method, 10 inpatients and 11 accompanying family members were selected for semi-structured interviews about unaccompanied ward prference, and the interview topics were summarized and extracted. The results of quantitative and qualitative were compared and integrated.Results:The quantitative research results showed that among the 805 inpatients included, 125 patients (13.03%) chose medical caregivers, 382 patients (39.83%) chose their spouses, and 272 patients (28.36%) chose their children; 411 patients (24.54%) did not choose medical caregivers due to financial burden; 509 patients (63.23%) believed that the cost of an unaccompanied ward should be less than 120 yuan/day. The qualitative research results showed that the interview data formed three themes, including the driving factors of caregiving form selection intention, the emotional tendency of caregiving form selection intention, and the assessment of the benefits and drawbacks of caregiving form selection intention. The mixed research results showed that the majority of inpatients choose their spouse or children accompany them, and their willingness to choose medical caregivers is mainly influenced by service costs and family labor. However, its did not affect patients who are young or have difficulty caring for them; Influenced by traditional Chinese culture, patients tended to choose relatives to accompany them; The main reasons why patients did not choose unaccompanied wards were the economic burden and the mismatch between medical nursing staff services and their expectations.Conclusions:Inpatients tended to choose family members to accompany them. Their willingness to choose unaccompanied ward was influenced by economic burden, family labor, patient age, caregiving difficulty, and filial piety culture.

Objective:To investigate the application and management status of midline catheters in 1 954 hospitals, providing a basis for optimizing intravenous therapy nursing practices.Methods:This study used convenience sampling. From November 2023, members of the Intravenous Therapy Nursing Professional Committee of the Chinese Nursing Association selected 1 954 hospitals across various regions of China. Questionnaire on the Current Status of Intravenous Therapy in Hospitals at All Levels designed by the committee, based on literature review and expert discussions, was used to collect data on intravenous therapy practices in different hospitals. Multiple response analysis was applied to analysis the results of multiple-choice questions, where response numbers represent the total number of times each option was selected, and response rates refer to the proportion of selected times for each option out of all selected responses.Results:A total of 1 954 questionnaires were distributed across 31 provinces/municipalities/autonomous regions, and 1 954 valid questionnaires were returned, achieving a 100.0% valid response rate. Among the hospitals surveyed, 844 used midline catheters. Regarding the skin disinfection area for midline catheter insertion, the highest response rate was for a range of>20 cm. The highest response rate for catheter insertion techniques was ultrasound-guided Seldinger puncture. The highest response rate for maintenance interval was once a week. The top three responses for nursing documentation related to midline catheters were informed consent for intubation, puncture record, and maintenance record. The most frequently chosen processes were catheter placement, maintenance, removal, and complication management processes. The qualification for midline catheter intravenous therapy specialist nurses was mostly obtained through specialized nurse training, followed by hospital-based and department-based training.Conclusions:The application of midline catheters has rapidly developed but still reveals some deficiencies, including the choice of puncture tools, infection control, and catheter maintenance. It is recommended to improve nursing documentation and management processes related to midline catheters, establish industry standards suitable for China's national conditions, and strengthen and standardize the specialized training of intravenous therapy nurses to promote the healthy development of intravenous therapy in China.
