Objective: To analyze the current status and influencing factors of postpartum depression symptoms among elderly multipara, so as to provide a basis for health management among elderly pregnant women. Methods: Multipara aged ≥35 years who underwent 42-day postpartum check-ups in Hangzhou Gynecology and Gynecology Hospital from October 2023 to October 2024 were selected as survey subjects using convenience sampling method. Demographic information, sleep quality and feeding methods data were collected using questionnaires. The postpartum depressive symptoms, parenting stress, and social support levels were assessed using the Chinese version of the Simplified Edinburgh Postnatal Depression Scale, Parenting Stress Inventory-Short Form, and Perceived Social Support Scale, respectively. Factors affecting postpartum depression symptoms among elderly multipara were analyzed through multivariable logistic regression model. Results: A total of 355 elderly multipara were surveyed. The average age was (38.19±2.10) years. There were 228 cesarean deliveries (64.23%) in this pregnancy. There were 21 cases (5.92%) of unplanned pregnancy and 21 cases (5.92%) of preterm birth. The parenting stress score was (72.56±11.08) points, and the social support score was (60.42±8.50) points. Postpartum depression symptoms was detected in 106 elderly multipara, with a detection rate of 29.86%. Multivariable logistic regression analysis showed that monthly household income per capita (≥5 000 yuan, OR=0.470, 95%CI: 0.281-0.785), unplanned pregnancy (yes, OR=2.619, 95%CI: 1.427-4.809), preterm delivery (yes,OR=4.105, 95%CI: 1.848-9.113), poor sleep quality (yes, OR=3.556, 95%CI: 1.659-7.595), feeding methods (mixed feeding, OR=1.483, 95%CI: 1.030-2.135; artificial feeding, OR=4.510, 95%CI: 2.018-10.070), parenting stress (OR=1.206, 95%CI: 1.162-1.441), and social support (OR=0.255, 95%CI: 0.111-0.420) were factors affecting postpartum depression symptoms among elderly multipara. Conclusion The detection rate of postpartum depression symptoms among elderly multiparas is relatively high, is associated with family economic status, pregnancy planning status, preterm delivery, sleep quality, feeding methods, parenting stress, and social support levels.

The liver regenerative capacity is crucial for patients with end-stage liver disease following partial hepatectomy (PHx). The specific bacteria and mechanisms regulating liver regeneration post-PHx remain unclear. This study demonstrated dynamic changes in the abundance of Parabacteroides distasonis (P. distasonis) post-PHx, correlating with hepatocyte proliferation. Treatment with live P. distasonis significantly promoted hepatocyte proliferation and liver regeneration after PHx. Targeted metabolomics revealed a significant positive correlation between P. distasonis and β-hydroxybutyric acid (BHB), as well as hyodeoxycholic acid and 3-hydroxyphenylacetic acid in the gut after PHx. Notably, treatment with BHB, but not hyodeoxycholic acid or 3-hydroxyphenylacetic acid, significantly promoted hepatocyte proliferation and liver regeneration in mice after PHx. Moreover, STAT3 inhibitor Stattic attenuated the promotive effects of BHB on cell proliferation and liver regeneration both in vitro and in vivo. Mechanistically, P. distasonis upregulated the expression of fatty acid oxidation-related proteins, and increased BHB levels in the liver, and then BHB activated the STAT3 signaling pathway to promote liver regeneration. This study, for the first time, identifies the involvement of P. distasonis and its associated metabolite BHB in promoting liver regeneration after PHx, providing new insights for considering P. distasonis and BHB as potential strategies for promoting hepatic regeneration.

【Objective】 To explore the effectiveness of using donor plasma reinfusion to flush the leukoreduction system (LRS) chamber during the final reinfusion phase with the Trima Accel automated blood collection system in preventing the reduction of CD4+ and CD8+ T lymphocytes. 【Methods】 A longitudinal and cross-sectional study was designed. CD4+ count<200 cells/μL and CD8+ count<125 cells/μL were considered as the criteria for deficiency. Eighteen first-time platelet donors were followed up. The lymphocyte count was measured at 0, 3-6 and 7-14 times of blood donation in the last 300 days. 170 healthy blood donors who have not donated blood were selected as the control group. According to the cut-off point(October 2021), 88 blood donors who mainly used automatic blood collection system to donate platelet apheresis in the last 365 days(median blood donation times ≥17.5)were divided into three groups(A, B and C)and blood samples were obtained. The time for Groups A, B and C started donating platelet apheresis were as follows: Group A: before October 2019, Group B: from October 2019 to September 2021, Group C: after October 2021. Blood samples were analyzed to obtain blood counts including CD4 + and CD8 + T lymphocytes. Blood samples were analyzed to obtain blood cell counts including CD4+ and CD8+ T lymphocytes. Through a comparative analysis, this study aimed to determine if there are any statistical differences in the detection indices between the follow-up groups with varying frequencies of blood donation, the control group, and groups A, B, and C. This approach was employed to infer the efficacy of donor plasma reinfusion in flushing the leukoreduction system (LRS) chamber for preventing the decline of CD4+ and CD8+ T lymphocytes. 【Results】 Eighteen first-time blood donors who were converted to regular platelet apheresis donors did not show a decrease of CD4 + and CD8 + T lymphocytes in the 5 th and 11 th blood donation (median number of blood donation), and there was no significant difference between the above indexes and those in the 0 th blood donation. Among the previous frequent blood donors, the CD4+ and CD8+ T lymphocyte counts in Group B and Group C are both higher than the standard value, showing no statistical difference from the control group. Among regular blood donors, the CD4+ and CD8+ T lymphocyte counts in groups B and C were higher than the criteria values, and had no statistical difference compared to the control group.The CD4+ T lymphocyte count in Group A was normal, with only one donor in Group A having a CD8+ T lymphocyte count below 125 cells/μL. This donor has donated 281 times of platelet apheresis, and the group he belongs to has started blood donation 2-21 years(median of 5 years) before the adjustment of reinfusion mode. The CD4+ and CD8+ T lymphocyte counts in Group A showed significant differences compared to the control group, with median counts (Group A/Control Group) of 359/521 and 257/372, respectively, P<0.001. In Group A, 0%(0/35) had a CD4+ count below 200 cells/μL, and 2.85%(1/35) of donors had a CD8+ count below 125 cells/μL, which was far lower than the proportion of CD4+ and CD8+ T cell deficiency found in regular apheresis donors by John M. Gansner and Mahboubeh Rahmani. The study showed that the adjustment of the plasma reinfusion mode did not further reduce the T lymphocyte counts in blood donors, but instead further restored the T lymphocyte counts in regular blood donors. This indicated that after the adjustment of plasma reinfusion mode, blood donors might not have lost CD4+ and CD8+ T lymphocytes during blood donation, or only lost a small amount, and can recover even if they donate platelet apheresis frequently. 【Conclusion】 Trima Accel automated blood collection system has a good effect on preventing CD4 + and CD8 + T lymphocytes from being reduced by flushing the LRS chamber with donor plasma.

The clinical practice guidelines of traditional Chinese medicine （TCM） have problems such as limited clinical application and unclear implementation effects， which may be related to the lack of clinical practice evidence. To provide reliable and precise evidence for clinical practice， this article proposes a model of combining TCM guidelines with real-world study， which includes 4 steps. Firstly， during the implementation process of the guidelines， a high-quality research database is established. Secondly， the recommendations in the guidelines are evaluated based on the established database in multiple dimensions， including applicability， effectiveness， safety， and cost-effectiveness， and thus their effectiveness in practical applications can be determined. Thirdly， based on the established database， core prescriptions are identified， and the targeted populations and medication plans are determined. That is， the best treatment regimen is established based on the analysis of abundant clinical data regarding the effects of different medication frequencies， dosages， and duration on efficacy. Fourthly， the guidelines are updated according to the real-world evidence. The research based on this model can provide real-world evidence for ancient and empirical prescriptions， improving their application in clinical practice. Moreover， this model can reduce research costs and improve research efficiency. When applying this model， researchers need to pay attention to the quality of real-world evidence， ensuring that it can truly reflect the situation in clinical practice. In addition， importance should be attached to the clinical application of guideline recommendations， ensuring that doctors can conduct standardized diagnosis and treatment according to the guidelines. Finally， full-process participation of multidisciplinary experts is encouraged to ensure the comprehensiveness and scientificity of the study. In conclusion， the application of this model will contribute to the development of TCM guidelines responsive to the needs of clinical practice and achieve the goal of promoting the homogenization of TCM clinical diagnosis and treatment.

BACKGROUND:Bone transport has been used for a variety of reasons in bone defects with good clinical results.However,various complications have also attracted the attention of practitioners and the avoidance of non-healing of the docking point has become a common concern for doctors and patients. OBJECTIVE:To explore effective methods of avoiding non-healing of the docking point in the treatment of tibial bone defects by bone transport so as to shorten the treatment period and reduce the pain of patients. METHODS:The clinical data of 21 patients with unilateral tibial bone defect admitted to the No.910 Hospital of Joint Logistics Support Force of Chinese PLA from January 2018 to January 2021 were retrospectively analyzed,including 16 males and 5 females,aged(32.8±10.3)years,with an average bone defect length of 10.2 cm.All 21 patients received bone transport surgery,during which the bone defect area was filled with bone cement to reduce the adverse factors affecting the healing of the docking point.The Association for the Study and Application of the Methods of Ilizarov,healing index and incidence of adverse reactions were evaluated during postoperative follow-up. RESULTS AND CONCLUSION:The 21 patients were followed up for 15 to 24 months after surgery,and the extended area was all well mineralized and had no malformations,and no refractures occurred during treatment.Among them,one patient had foot drop,which could not be completely corrected after surgical release of the Achilles tendon and wearing foot and ankle orthotics.19 patients had different degrees of needle tract infection,and no deep infection occurred after timely needle tract nursing.The healing rate of the docking point was 100%;the healing index was 36-45 d/cm and the average was 38 d/cm.The Association for the Study and Application of the Methods of Ilizarov showed that bone healing was excellent in 17 cases(81%)and poor in 4 cases(19%).The results of limb function were excellent in 18 cases(86%)and good in 3 cases(14%).These findings show that bone cement segmental filling during bone transport is an effective method to solve the non-healing of the docking point,shorten the patient's treatment period and reduce the patient's pain.

Objective The aim is to provide drug regimen for patients who have hormone allergy history but need hor-mone therapy.Methods Pharmacists analyzed the sensitization mechanism of methylprednone in combination with insturction and literature,assisted clinicians to formulate oral hormone therapy for tuberculosis meningitis with history of menthylprednisolone and verified the effectiveness and safety of the drug regimen.Results Methylprednisolone injection contains trace amount of milk protein and should not be used in patients with definite allergy to cow's milk.After changing to oral hormone therapy,the patient did not appear allergic again,and the condition was stable.Conclusion Gucocorticoids can also induce allergic reactions,so patients'previous allergic history should be paid attention in the process of medical history collection.Meanwhile,pharmacists can also give full play to their pharmaceutical expertise to assist clinicians in formulating individualized drug administration plans to ensure the effectiveness and safety of patients.

With the development of clinical related disciplines, the update and establishment of relevant standards/guidelines at home and abroad, GBZ 185-2006 Diagnostic Criteria for Occupational Medicamentose-like Dermatitis due to Trichloroethylene (hereinafter referred to as “GBZ 185-2006”) was unable to meet clinical needs. Therefore, the GBZ 185-2006 was revised based on the principles of evidence-based medicine, in accordance with relevant laws/regulations and relevant standards/guidelines in combination with review of research data on occupational medicamentose-like dermatitis due to trichloroethylene (OMDT) home and abroad, and the development of clinical practice and clinical related disciplines. The main modifications include: adding terms and definitions of OMDT, modifying the description of clinical manifestations of the diagnostic principles, adjusting the description of latency, deleting the diagnostic requirement of the incidence probability, adding the specific allergen patch test as the etiological diagnostic index, standardizing the application scope, operating procedure and precautions of the specific allergen patch test. In addition, the relevant content of “Basic Characteristics and Clinical Types of Skin Damage of Medicamentose-like Dermatitis due to Trichloroethylene” in Appendix A is improved, the treatment principles are revised, and the content of new progress in treatment, artificial liver application, are added. The revised GBZ 185-2024 Diagnostic Standard for Occupational Medicamentose-like Dermatitis due to Trichloroethylene is more scientific and practical, and can provide technical basis for the standardized diagnosis and treatment of OMDT in medical and health institutions.

Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

OBJECTIVE To establish the HPLC fingerprint and content determination of five components in Ranunculus sceleratus L.. METHODS The separation was developed on an Agilent ZORBAX SB C18 chromatographic (4.6 mm×250 mm, 5 μm)column by gradient elution with methanol(A)-0.1 % phosphoric acid aqueous solution(B) as mobile phase to establish HPLC fingerprint of Ranunculus sceleratus L.. Combined with similarity evaluation, cluster analysis, principal component analysis, and orthogonal partial least squares-discriminant analysis, the quality of 13 batches of Ranunculus sceleratus L. was evaluated. RESULTS Thirteen batches of Ranunculus sceleratus L. samples were calibrated with 20 common peaks, of which 5 common peaks were identified, and the similarity ranged from 0.874 to 0.984. The results of cluster analysis and principal component analysis were basically the same, indicating that there might be differences in the content of chemical components of Ranunculus sceleratus L. in different regions. Protocatechuic aldehyde, caffeic acid, ferulic acid, hyperoside and isoquercitrin were determined in thirteen batches of Ranunculus sceleratus L., and their contents were 0.016−0.035, 0.010−0.070, 0.010−0.029, 0.016−0.051, 0.028−0.086 mg·g–1, respectively. CONCLUSION The established HPLC fingerprint and content determination method is simple, stable, and reliable, which can be used for qualitative analysis and provide reference to quality evaluation and resource utilization of Ranunculus sceleratus L..
