OBJECTIVE: To observe the variability of hemoglobin (HB) level in patients with renal anemia, and to analyze its relationship with effect of repeated blood transfusion therapeutic in patients. METHODS: A retrospective cohort study and propensity score matching method were used, 60 patients with renal anemia who had effective treatment with repeated blood transfusion in Changzhou No.2 People's Hospital from May 2018 to May 2021 were retrospectively analyzed and set as the effective group; 153 patients with renal anemia who had ineffective treatment with repeated blood transfusion in the hospital in the same period were collected and set as the ineffective group, the propensity score matching method was used, the patients who were effective and ineffective in repeated blood transfusion were matched 1∶1 for analysis; the medical records and laboratory indexes of the two groups were checked; the Hb level of patients within 6 months (1/month) were recorded, the residual standard deviation (Res-SD) of Hb of patients was calculated according to the Hb level and evaluated the variability of Hb level; the relationship between HB variability level and therapeutic effect of repeated blood transfusion in patients with renal anemia was analyzed. RESULTS: After propensity score matching, there was no statistical significant difference between the two groups in terms of baseline data such as age, sex, dialysis age and BMI (P>0.05). The levels of serum albumin and transferrin of patients in the ineffective group were significantly lower than those of patients in the effective group (P<0.05); at 1 and 2 months of the observation period, there was no statistical significant difference in Hb levels of patients in both groups (P>0.05); the Hb level of patients in the ineffective group was significantly lower than that of patients in the effective group at 3, 5 and 6 months, and significantly higher than that of patients in the effective group at 4 months (P<0.05); the Res-SD of male patients and female patients in the ineffective group were respectively significantly higher than that of male patients and female patients in the effective group (P<0.05). Logistic regression analysis results showed that high variability of Hb level (Res-SD) was a risk factor for the ineffective treatment of repeated blood transfusion in patients with renal anemia (OR>1, P<0.05); the decision curve results showed that, when the high-risk threshold was 0.0-1.0, Res-SD predicted the net benefit rates of male and female patients with renal anemia were greater than 0, which was clinically significant, the smaller the high-risk threshold in the above range, the greater the net benefit rate. CONCLUSION The therapeutic effect of repeated blood transfusion in patients with renal anemia may be related to the variability of Hb level.

Objective: To evaluate the efficacy and safety of intravenous iron supplementation in patients with recurrent iron deficiency anemia (IDA) . Methods: This retrospective analysis of 90 patients with recurrent IDA from May 2012 to December 2021 was conducted, comparing the efficacy and safety of the intravenous iron therapy group and the oral iron therapy group. Results: Among the 90 patients with recurrent IDA, 20 were males and 70 were females, with a median age of 40 (range: 14-85) years. A total of 60 patients received intravenous iron supplementation and 30 received oral iron supplementation. The hematologic response rates in the intravenous iron group were significantly higher than those in the oral iron group at 4 and 8 weeks after treatment [80.0% (48/60) vs 3.3% (1/30) and 96.7% (58/60) vs 46.7% (14/30), all P<0.001, respectively]. The median increase in hemoglobin levels was also significantly higher in the intravenous iron group than in the oral iron group [38 (4, 66) g/L vs 7 (1, 22) g/L at week 4 and 44.5 (18, 80) g/L vs 19 (3, 53) g/L at week 8, all P<0.001]. The intravenous iron group had a significantly higher proportion of patients who achieved normal hemoglobin levels than the oral iron group (55.0% vs 0 and 90% vs 43.3%, all P<0.001, respectively). Iron metabolism indicators were tested before and after 8 weeks of treatment in 26 and 7 patients in the intravenous and oral iron groups, respectively. The median increase in serum ferritin (SF) levels in the intravenous iron group 8 weeks after treatment was 113.7 (49.7, 413.5) μg/L, and 54% (14/26) of these patients had SF levels of ≥100 μg/L, which was significantly higher than the median increase in SF levels in the oral iron group [14.0 (5.8, 84.2) μg/L, t=4.760, P<0.001] and the proportion of patients with SF levels of ≥100 μg/L (P=0.013). The incidence of adverse reactions was 3.3% (2/60) in the intravenous iron group, which was significantly lower than that in the oral iron group [20.0% (6/30), P=0.015]. Conclusion: Intravenous iron supplementation is more effective for hematologic response, faster hemoglobin increase, and higher iron storage replenishment rates compared with oral iron supplementation in patients with recurrent IDA, and it is well tolerated by patients.

Objective: To evaluate different methods' efficacy of controlling acute bleeding and managing long-term menstruation in patients with heavy menstrual bleeding (HMB) associated with antithrombotic therapy. Methods: The clinical data of 22 cases with HMB associated with antithrombotic therapy admitted to Peking University People's Hospital from January 2010 to August 2022 were analyzed, aged 39 years old (26-46 years). Changes in menstrual volume, hemoglobin (Hb), and quality of life were collected after control of acute bleeding and long-term menstrual management. Menstrual volume was assessed by pictorial blood assessment chart (PBAC), and quality of life was assessed by menorrhagia multi-attribute scale (MMAS). Results: (1) Treatment of acute bleeding: of the 22 cases with HMB associated with antithrombotic therapy, 16 cases were treated in our hospital and 6 in other hospital for emergency bleeding; of the 16 cases treated in our hospital, 3 underwent emergency intrauterine Foley catheter balloon compression due to severe bleeding (Hb decreased by 20 to 40 g/L within 12 hours). Of the 22 cases with antithrombotic therapy-related HMB, 15 (including 2 cases with severe bleeding) underwent emergency aspiration or endometrial resection, and intraoperative placement of levonorgestrel-releasing intrauterine system (LNG-IUS) followed by a significant reduction in bleeding volume; 3 cases had controlled acute bleeding after rivaroxaban dose reduction and continued observation; 2 cases were given gonadotropin-releasing hormone agonists to control acute bleeding in other hospital, of which 1 case was temporarily treated with periodic blood transfusion, and the other one patient underwent total hysterectomy; and 2 cases had temporary amenorrhea with oral mifepristone after intrauterine balloon compression or oral norethindrone. (2) Long-term menstrual management: of the 22 cases with antithrombotic therapy-related HMB, 15 had LNG-IUS placement and 12 had LNG-IUS placement for 6 months, and menstrual volume was significantly reduced [PBAC scores were 365.0 (272.5-460.0) vs 25.0 (12.5-37.5), respectively; Z=4.593, P<0.001], Hb was significantly increased [91.5 g/L (71.8-108.2 g/L) vs 128.5 g/L (121.2-142.5 g/L); Z=4.695, P<0.001], and quality of life was significantly improved [MMAS scores were 415.0 (327.5-472.5) vs 580.0 (570.0-580.0), respectively; Z=-3.062, P=0.002] before placement compared with 6 months after placement. Three rivaroxaban dose reduction patients' PBAC scores decreased by 20 to 35 but remained >100, and perceived quality of life did not change significantly. Two cases with temporary amenorrhea treated with oral mifepristone felt significantly improved quality of life, and the MMAS scores increased by 220 and 180, respectively. Conclusion: Intrauterine Foley catheter balloon compression, aspiration or endometrial ablation could be used to control acute bleeding in patients with antithrombotic therapy-related HMB, and LNG-IUS for long-term management could reduce menstrual volume, increase hemoglobin, and improve the quality of life of patients.

OBJECTIVE: To systematically evaluate the hemostatic efficacy of tranexamic acid and ε-aminocaproic acid in total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: Randomized controlled trials (RCT) and retrospective case-control studies about tranexamic acid and ε-aminocaproic acid for the comparison of THA or TKA were searched electronically in PubMed, EMbase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, VIP from the time of building databases to July 2020. Two investigators carried out literature screening and data extraction according to the inclusion and exclusion criteria respectively. The methodological quality of the included randomized controlled studies was evaluated through the Cochrane Handbook, and the methodological quality of the included retrospective case-control studies was evaluated through the NOS scale. Blood loss, the incidence of thrombosis complications, per capita input of hemoglobin were Meta-analyzed by Review Manager 5.3 software. RESULTS: A total of 6 articles were included, including 4 RCTs and 2 retrospective case-control studies. A total of 3 174 patients, including 1 353 in the tranexamic acid group and 1 821 in the ε-aminocaproic acid group. Meta-analysis results showed that there were no difference statistical significance in blood loss [MD=-88.60, 95%CI(-260.30, 83.10), P=0.31], blood transfusion rate [OR=1.48, 95%CI(0.96, 2.27), P=0.08], thrombotic complications [OR=0.80, 95%CI(0.07, 8.83), P=0.85], per capita hemoglobin input [MD=0.04, 95%CI(-0.02, 0.10), P=0.18] between tranexamic acid group and ε-aminocaproic acid group during THA. While in TKA, the blood loss of the tranexamic acid group was less than that of the ε-aminocaproic acid group [MD=-147.13, 95%CI(-216.52, -77.74), P<0.0001], the difference was statistically significant. The blood transfusion rate [OR=1.30, 95%CI(0.74, 2.28), P=0.37], thrombotic complications [OR=0.95, 95%CI(0.38, 2.36), P=0.92], per capita hemoglobin input [MD=-0.00, 95%CI(-0.05, 0.06), P=0.48], tourniquet time [MD=1.54, 95%CI(-2.07, 5.14), P=0.40] were similar between two groups, the difference was not statistically significant. CONCLUSION In THA, tranexamic acid and ε-aminocaproic acid have similar hemostatic effects, while in TKA, tranexamic acid can effectively reduce the patient's blood loss and has a better hemostatic effect. Tranexamic acid is recommended as one of the first choice hemostatic drugs for TKA.

OBJECTIVE: To investigate the prognostic value of hemopoietic scoring system composed of hemoglobin (HB), platelet count (PLT) and mean corpuscular volume (MCV) in MM patients and its correlation with curative effect. METHODS: The clinical data of 172 newly diagnosed MM patients treated by bortezomib as the first-line regimen in our hospital from May 2014 to December 2019 were collected, three variables (HB≤100 g/L, PLT≤150×10⁹/L, MCV≥96 fl) were introduced, each variable was distributed 1 score, the patients were divided into four groups (0, 1, 2 and 3 points in group 1, 2, 3 and 4, respectively), and the clinical characteristics and prognosis of the patients in the four groups were analyzed. The initial efficacy evaluation after 3-4 courses of treatment was carried out, and the curative effect of the patients in the different hematopoiesis score groups were compared. RESULTS: The median OS time of the patients in group 1, 2, 3 and 4 was 27.0, 22.5, 20.7 and 18.1 months, while the median PFS time were 23.0, 19.0, 18.0 and 14.0 months, respectively. The OS and PFS of the patients in low score group were significantly better than those in high score group (P=0.045, P=0.048). There was no significant difference in the curative effect of the patients treated by bortezomib after 3-4 courses (P>0.05). CONCLUSION Hematopoiesis score can preliminarily predict the overall survival of newly diagnosed MM patients, but there is no significant difference between different scoring groups in the initial curative effect.

OBJECTIVE: To evaluate the efficacy and safety of ruxolitinib in patients with polycythemia vera (PV). METHODS: The clinical data of patients with PV treated with ruxolitinib in Peking Union Medical College Hospital from January 1, 2013 to December 31, 2019 were retrospectively analyzed. The starting dose of oral ruxolitinib was 10 mg twice daily and could be increased after 3 months of treatment if hematocrit (HCT) control was not achieved. HCT control was defined as HCT<45% in the absence of phlebotomy. RESULTS: Thirty-three patients (17 males and 16 females) were treated with ruxolitinib at a median age of 50 (21-72) years. JAK2V617F and JAK2exon12 alleles were detected in 31 and 2 patients, respectively. Before treatment, median hemoglobin level was 187 (166-208) g/L, median white blood cell and platelet level was 10.4 (5.0-15.8)×10⁹/L and 457(237-677)×10⁹/L, respectively. Totally 17 patients (51.5%) who were resistant to or intolerant of hydroxyurea were treated with ruxolitinib as second-line therapy, and 16 patients (48.5%) were treated with ruxolitinib as first-line therapy voluntarily. The median time since PV diagnosis to treatment of ruxolitinib was 47 (3-188) months. By December 31, 2019, all the patients continued to receive ruxolitinib. The median duration of ruxolitinib exposure was 19 (2-91) months. Both in the first-line therapy group and second-line therapy group, 15 cases (accounting for 93.8% and 88.2%, respecitvely) achieved HCT control. The median time from start of therapy to HCT control was 2.2 (0.8-11.6) months. One patient (3.0%) had disease progression after HCT control. The most common hematologic adverse events included anemia and thrombocytopenia, according to CTCAE classification, including 1 case of grade 1 anemia (3.0%) and 1 case of grade 2 thrombocytopenia (3.0%). There was no thromboembolic event occurred during the therapy of ruxolitinib. CONCLUSION The remission rate of HCT in PV patients treated with ruxolitinib is high, and adverse reactions are rare. Ruxolitinib is effective in HCT control and generally well tolerated in patients with PV.

OBJECTIVE: To compare the clinical efficacy and safety of oral administration of Buxue Yimu Pills (BYP, ), ferrous sulfate (FS), and the combination of BYP and FS on gynecological anemia, and investigate the mechanisms using network pharmacology. METHODS: A randomized, controlled, multi-center clinical trial was conducted. Totally 150 patients with hemoglobin of 70-110 g/L due to gynecological conditions were recruited and randomized (using the block randomization method) into Buxue Yimu Pills group (24 g/d), oral iron group (FS Tablets, 0.9 g/d), and combined treatment group (BYP, 24 g/d plus FS Tablets, 0.9 g/d), 50 patients in each group. At the enrollment and 4-week treatment, complete blood count, serum iron indexes were evaluated. Adverse events, liver and renal functions, as well as blood coagulation were observed. Network pharmacology was conducted to identify the active ingredients and explore the potential mechanisms of BYP. RESULTS: Ten (20%) and 7 (14%) participants discontinued the therapy due to gastrointestinal symptoms in oral iron and combination treatment groups. All 3 groups showed elevated hemoglobin. The patients in the iron group exhibited typically elevated in serum iron and ferritin and decreased in total iron-binding capacity. No change in iron indexes was observed in BYP group. The patients in the combination treatment group neither showed significant changes in serum ferritin nor total iron-binding capacity. No significant adverse reactions were observed in the BYP group. The network pharmacology identified 27 bioactive compounds and 145 targets of BYP on gynecological anemia. Biological processes and pathways including regulation of inflammation, hormone, angiogenesis and hemostasis, response to decreased oxygen levels, effects on myeloma cell, and response to metal ions were identified. CONCLUSION BYP contributes to the practical improvement on gynecological anemia potentially through multi-target mechanisms and optimized iron re-distribution. (Trial registration: No. NCT03232554).

Oxygen plays an important role in the process of wound healing. Researches have shown that more than 97% of chronic wounds are in a state of hypoxia, which is one of the key factors resulting in refractory wounds. Local oxygen therapy is a treatment method that can directly provide oxygen to wounds without relying on the damaged vascular system. It can effectively promote chronic wounds healing by transmitting sufficient oxygen to wounds through specific devices or preparations. Hemoglobin spray is a new form of local oxygen therapy, which has the advantages of good effect, simple operation, and low cost. This article reviews the development, component, safety, oxygen supply principle, and application methods of hemoglobin spray and its effects in the treatment of chronic wounds, so as to provide a new direction for the treatment of chronic wounds.

OBJECTIVE: Critically ill patients with solid tumors complicated with paraneoplastic pemphigus are usually treated in intensive care units (ICU) for perioperative management after surgical treatment. In this study, the clinical characteristics and predictors of long-term prognosis of these critically ill patients were analyzed. METHODS: the clinical and laboratory data of 63 patients with solid tumors complicated with paraneoplastic pemphigus admitted to ICU from 2005 to 2020 were retrospectively analyzed, and the survival status of the patients were followed up. RESULTS: Among the 63 patients, 79.4% had Castleman disease as the primary tumor, and 20.6% with other pathological types; 69.8% had severe-extensive skin lesions, and 30.2% had other skin lesions; the patients with bronchiolitis obliterans accounted for 44.4%, and 55.6% were not merged. Postoperative fungal infection occurred in 23.8% of the patients, and 76.2% without fungal infection. The median follow-up time was 95 months, and 25 patients died during the study period. The 1-year, 3-year and 5-year survival rates were 74.6% (95%CI 63.8%-85.4%), 67.4% (95%CI 55.6%-79.2%) and 55.1% (95%CI 47.9%-62.3%), respectively. The log-rank univariate analysis showed that the patients had age>40 years (P=0.042), preoperative weight loss>5 kg (P=0.002), preoperative albumin < 30 g/L (P < 0.001), paraneoplastic pemphigus complicated with bronchiolitis obliterans (P=0.002), and perioperative fungal infection (P < 0.001) had increased mortality. Cox univariate analysis showed that preoperative weight loss >5 kg (P=0.005), preoperative albumin < 30 g/L (P < 0.001), paraneoplastic pemphigus complicated with bronchiolitis obliterans (P=0.009), preoperative bacterial pulmonary infection (P=0.007), prolonged surgical time (P=0.048), postoperative oxygenation index (P=0.012) and low albumin (P=0.010) and hemoglobin concentration (P=0.035) in ICU, acute physiology and chronic health evaluation (APACHE Ⅱ) score (P=0.001); sequential organ failure assessment (SOFA) score (P=0.010), and postoperative fungal infection (P < 0.001) were risk factors for long-term survival. Cox regression model for multivariate analysis showed that preoperative weight loss > 5 kg (HR 4.44; 95%CI 1.47-13.38; P=0.008), and preoperative albumin < 30 g/L (HR 4.38; 95%CI 1.72-11.12; P=0.002), bronchiolitis obliterans (HR 2.69; 95%CI 1.12-6.50; P=0.027), and postoperative fungal infection (HR 4.85; 95%CI 2.01-11.72; P < 0.001) were independent risk factors for postoperative mortality. CONCLUSION The 5-year survival rate of critically ill patients undergoing surgery for paraneoplastic pemphigus combined with solid tumors is approximately 55.1%, with preoperative weight loss > 5 kg, albumin < 30 g/L, bronchiolitis obliterans and postoperative fungal infection were associated with an increased risk of near- and long-term postoperative mortality.

OBJECTIVES: To summarize the clinical features of liver damage in children in the acute stage of Kawasaki disease (KD), and to investigate the clinical value of liver damage in predicting coronary artery lesion and no response to intravenous immunoglobulin (IVIG) in children with KD. METHODS: The medical data were collected from 925 children who were diagnosed with KD for the first time in Beijing Children's Hospital from January 1, 2016 to December 31, 2017. According to the presence or absence of abnormal alanine aminotransferase (ALT) level on admission, the children were divided into a liver damage group (n=284) and a non-liver damage group (n=641). A logistic regression analysis was used to investigate the clinical value of the indicators including liver damage in predicting coronary artery lesion and no response to IVIG in children with KD. RESULTS: Compared with the non-liver damage group, the liver damage group had a significantly earlier admission time and significantly higher serum levels of inflammatory indicators (P<0.05). The liver damage group had a significantly higher incidence rate of coronary artery lesion on admission than the non-liver damage group (P=0.034). After initial IVIG therapy, the liver damage group had a significantly higher proportion of children with no response to IVIG than the non-liver damage group (P<0.001). In children with KD, coronary artery lesion was associated with the reduction in the hemoglobin level and the increases in platelet count, C-reactive protein, and ALT (P<0.05), and no response to IVIG was associated with limb changes, the reduction in the hemoglobin level, the increases in platelet count, C-reactive protein, and ALT, and coronary artery lesion (P<0.05). CONCLUSIONS Compared with those without liver damage, the children in the early stage of KD with liver damage tend to develop clinical symptoms early and have higher levels of inflammatory indicators, and they are more likely to have coronary artery lesion and show no response to IVIG treatment.
