RESUMO
BACKGROUND: Intramural hematoma of the small bowel is a rare yet acute gastrointestinal condition typically linked with impaired coagulation function, often posing diagnostic challenges. It is principally encountered in patients undergoing prolonged anticoagulant therapy, specifically warfarin. CASE PRESENTATION: We reported a case of intramural hematoma associated with warfarin use. The patient was admitted to hospital with abdominal pain and had received anticoagulant therapy with warfarin 2.5 mg/day for 4 years. Laboratory examination showed decreased coagulation function, abdominal CT showed obvious thickening and swelling of part of the jejunal wall, and abdominal puncture found no gastroenteric fluid or purulent fluid. We treated the patient with vitamin K and fresh frozen plasma. The patient was discharged after the recovery of coagulation function. Then we undertaook a comprehensive review of relevant case reports to extract shared clinical features and effective therapeutic strategies. CONCLUSION: Our analysis highlights that hematoma in the small intestinal wall caused by warfarin overdose often presents as sudden and intense abdominal pain, laboratory tests suggest reduced coagulation capacity, and imaging often shows thickening of the intestinal wall. Intravenous vitamin K and plasma supplementation are effective non-surgical strategies. Nevertheless, in instances of severe obstruction and unresponsive hemostasis, surgical resection of necrotic intestinal segments may be necessary. In the cases we reported, we avoided surgery by closely monitoring the coagulation function. Therefore, we suggest that identifying and correcting the impaired coagulation status of patient is essential for timely and appropriate treatment.

OBJECTIVE: To evaluate the effects of argatroban on the levels of Hcy, hs-CRP and FIB in patients with acute cerebral infarction (ACI). METHODS: A retrospective analysis was performed on 382 patients with ACI who were hospitalized in the Department of Neurology of our hospital from January 2017 to December 2019. Among them, 158 patients received conventional treatment as the control group and 224 patients received combined treatment with argatroban as the study group. NHISS score, mRS score, Hcy, hs-CRP, FIB level, quality of life, adverse reactions were compared between the two groups after treatment. The levels of Hcy and hs-CRP in patients with different mRS scores were compared. RESULTS: A superior clinical efficacy of the study group was observed than the control group (p < 0.05). The study group witnessed a remarkably lower NHISS score, Hcy, hs-CRP and FIB level as compare to the control group (p < 0.05). The ADL and FMA scores in the study group were higher than those in the control group (p < 0.05). The levels of Hcy and hs-CRP in mRS 0-2 patients were lower than those in mRS 3-6 patients (p < 0.05). CONCLUSION: Argatroban in ACI patients can significantly enhance the clinical efficacy and improve the quality of life. It is closely related to the reduction of Hcy and hs-CRP levels, but the mechanism needs to be further studied.
RESUMO
This retrospective study analyzed the efficacy of combined antiplatelet therapy with Argatroban in treating acute ischemic stroke (AIS) and its impact on patients' coagulation and neurological functions. Clinical data of 113 AIS patients admitted between January 2021 and January 2023 were retrospectively analyzed. Patients were divided into control (n = 56) and observation (n = 57) groups based on treatment interventions. The control group patients were treated with antiplatelet drugs, while the observation group patients received combination therapy with apatinib on the basis of the control group treatment. Compared to the control group, the observation group demonstrated higher clinical efficacy, improved coagulation parameters, reduced stroke severity (measured by NIHSS), enhanced daily living abilities (BI scores), and lowered inflammatory and neural injury markers post-treatment. Adverse reaction incidence was similar between groups. Combining Argatroban with antiplatelet drugs in AIS management showed superior efficacy without increasing adverse effects, suggesting its potential for clinical application.
RESUMO
OBJECTIVE: To analyze the effects of Butylphthalide on cerebral vascular circulation, coagulation function, and neurological function in patients with acute severe ischemic stroke following intravenous thrombolysis. METHODS: Clinical efficacy, cerebral vascular circulation indicators [anterior cerebral artery (ACA), middle cerebral artery (MCA), vertebral artery (VA) blood flow velocity], coagulation function indicators [prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (FIB)], neurological function indicators [Activities of Daily Living (ADL) score. RESULTS: The total effective rate of treatment in the control group was 76.47%, while in the observation group, it was 96.08%, with the observation group showing a significantly higher total effective rate than the control group (p < 0.05). Before treatment, there was no significant difference in ACA, MCA, and VA blood flow velocity between the two groups (p > 0.05). However, after treatment, the ACA, MCA, and VA blood flow velocity in the observation group were significantly higher than those in the control group (p < 0.05). Before treatment, there was no significant difference in PT, APTT, TT, and FIB levels between the two groups (p > 0.05). CONCLUSION: In patients with acute severe ischemic stroke undergoing intravenous thrombolysis, the addition of Butylphthalide to the treatment regimen yields favorable clinical outcomes. Compared to Alteplase alone, the addition of Butylphthalide further improves cerebral vascular circulation and coagulation function, promoting the recovery and reconstruction of neurological function in patients. Importantly, the addition of Butylphthalide does not increase the risk of adverse reactions, making it a safe and ideal option for clinical application.
RESUMO
Reports of rare but severe thrombotic events after receiving some COVID-19 vaccines brought concerns for the possibility of vaccine-induced coagulation abnormality. However, no study has reported the impacts of COVID-19 vaccination on coagulation function in pregnant women. We aimed to explore whether vaccination with inactivated COVID-19 vaccines before pregnancy was associated with coagulation changes in pregnant women. We conducted a retrospective cohort study in a tertiary-care hospital in Shanghai, China. A total of 5166 pregnant women were included, of whom 2721 (52.7%) completed vaccination before conception. Compared with unvaccinated women, the mean serum levels of prothrombin time (PT) and fibrinogen (FIB) were lower in vaccinated women by 0.09 (ß = -0.09, 95% confidence interval [CI], -0.13, -0.05) mg/L and 0.11 (ß = -0.11, 95% CI, -0.15, -0.07) mg/L, and the mean D-Dimer (D-D) levels were higher by 0.12 (ß = 0.12, 95% CI, 0.09, 0.15) mg/L. However, no significant association was observed between COVID-19 vaccination and serum levels of activated partial thromboplastin time (APTT), fibrinogen degradation product (FDP) or thrombin time (TT). Our findings suggested that inactivated COVID-19 vaccination before conception resulted in a small change in maternal coagulation function, but this might not have clinical significance.

OBJECTIVE: Post-operative bleeding after total knee arthroplasty (TKA) is a frequent cause of post-operative complications. This study compared blood loss and indicators of coagulation and fibrinolysis between TKA patients living at low or high altitudes. METHODS: We retrospectively analyzed 120 patients at our institution who underwent primary TKA from May 2019 to March 2020, and we divided them into those living in areas about 500 m or > 3000 m above sea level. We compared the primary outcome of total blood loss between them. We also compared them in terms of several secondary outcomes: coagulation and fibrinolysis parameters, platelet count, reduction in hemoglobin, hidden blood loss, intra-operative blood loss, transfusion rate, and incidence of thromboembolic events and other complications. RESULTS: Total blood loss was significantly higher in the high-altitude group than in the low-altitude group (mean, 748.2 mL [95% CI, 658.5-837.9] vs 556.6 mL [95% CI, 496.0-617.1]; p = 0.001). The high-altitude group also showed significantly longer activated partial thromboplastin time, prothrombin time, and thrombin time before surgery and on post-operative day one, as well as increased levels of fibrinogen/fibrin degradation product on post-operative days one and three. Ecchymosis was significantly more frequent in the high-altitude group (41.7 vs 21.7%; relative risk (RR) = 1.923 [95% CI, 1.091-3.389]; p = 0.019). The two groups showed similar transfusion rates, and none of the patients experienced venous thromboembolism, pulmonary embolism, or infection. CONCLUSION: High altitude may alter coagulation and fibrinolysis parameters in a way that increases risk of blood loss after TKA. Such patients may benefit from special management to avoid bleeding events.

OBJECTIVES: The number of gestational women has been increased in recent years, resulting in more adverse pregnancy outcomes. It is crucial to assess the coagulation function of pregnant women and to intervene in a timely manner. This study aims to analyze the influencing factors on thrombelastography (TEG) and explore the evaluation of TEG for gestational women. METHODS: A retrospective study was conducted on 449 pregnant women who were hospitalized in the obstetrics department in Xiangya Hospital of Central South University from 2018 to 2020. We compared the changes on the TEG parameters among normal pregnant women between different age groups, different ingravidation groups, and different stages of pregnancy groups. The influence on TEG of hypertensive disorders in pregnancy (HDP) and gestational diabetes mellitus (GDM) as well as two diseases synchronization was explored. RESULTS: Compared with the normal second trimester women, the R values and K values of TEG were increased, and α angle, CI values and LY30 values were decreased in third trimester women (all P<0.05). Compared with normal group, the R values and CI values of TEG of the HDP group have significant difference (both P<0.05). There were no significant difference of TEG between the GDM group, the HDP combined with GDM group and the normal group (all P>0.05). Multiple linear regression analysis showed that the influencing factors for R value in TEG were weeks of gestation (P<0.001) and mode of conception (P<0.05), for α angle was weeks of gestation (P<0.05), for MA value was mode of conception (P<0.05), and for CI value was weeks of gestation (P<0.05). The analysis of correlation between TEG with platelet (PLT) and coagulation routines represented that there was a correlation between TEG R values and activated partial thromboplastin time (APTT) (P<0.01), and negative correlation between TEG CI values and APTT (P<0.05). There was a negative correlation between TEG K values and FIB (P<0.05). The correlation of α angle (P<0.05), MA values (P<0.01) and CI values (P<0.05) with FIB were positive respectively. CONCLUSIONS: The TEG parameters of 3 stages of pregnancy were different. The different ingravidation approach has effect on TEG. The TEG parameters were consistent with conventional coagulation indicators. The TEG can be used to screen the coagulation status of gestational women, recognize the abnormalities of coagulation and prevent the severe complication timely.

BACKGROUND: The role of CD59 and fluorescently labeled aerolysin (FLAER) in acute myeloid leukemia (AML) remains unclear and requires further investigation. To explore the relationship between CD59, FLAER, and AML, we investigated CD59 and FLAER expression in AML and analyzed their relationship with clinical characteristics of AML patients. METHODS: We employed flow cytometry (FCM) to analyze CD59 and FLAER expression in 161 AML patients at Tianjin Medical University General Hospital and evaluated its association with sex, white blood cell (WBC) count, platelet (PLT) count, thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), D-Dimer(D-D), and lactate dehydrogenase (LDH), followed by analyzing its connection with disease progression and complete remission (CR). RESULTS: CD59 and FLAER deficiencies were identified in AML patients. Compared with CR group, non-CR group patients revealed more CD59 and FLAER deficiency. Compared with non-acute promyelocytic leukemia (M3) group, M3 group patients had more CD59 and FLAER deficiency. CD59- level in primordial cells of M3 patients was positively correlated with primordial cell ratio (r = 0.660, p = 0.003). Additionally, we discovered that the decline in CD59 and FLAER levels might be linked to higher D-D and LDH in AML patients. The difference was statistically significant (p < 0.05). CONCLUSIONS: We demonstrated that the decline in CD59 and FLAER levels was associated with leukemia cell proliferation and abnormal coagulation function in AML, suggesting that they could serve as a predictor of AML coagulation dysfunction, particularly in M3.

Objectives: To investigate the effects of tigecycline combined with Cefoperazone on bacterial clearance and the expression of serum biochemical indexes [C-reactive protein (CRP), leukocyte count (WBC) and procalcitonin (PCT)] in patients with infection in an intensive care unit (ICU). Methods: The clinical data of 79 patients with pulmonary infections within the ICU of Chenzhou first people's Hospital from October 2019 to September 2021 were retrospectively analyzed. From the total, 38 patients received intravenous drip of Cefoperazone (control group), and 41 patients received intravenous drip of Cefoperazone and tigecycline (observation group). The treatment effect, bacterial clearance effect, serum biochemical index level and adverse reactions of the two groups were counted before and after treatment. Results: The total efficacy in the observation group (95.12%) was higher than that of the control group (78.95%) (P<0.05). After treatment, the bacterial clearance rate in the observation group (87.04%) was higher than that in the control group (66.67%) (P<0.05). After treatment, the levels of CRP, WBC and PCT in the two groups were lower than those before treatment (P<0.05), and the levels in the observation group were lower than those in the control group (P<0.05). There was no significant difference in the incidence of adverse reactions between the observation group (9.76%) and the control group (5.26%) (P>0.05). Conclusions: The combination of Cefoperazone and tigecycline in the treatment of ICU infection can effectively improve the treatment effect of the disease, have a significant bacterial clearance effect, and can reduce the serum levels of CRP, WBC and PCT.
RESUMO
A boy, aged 2 years and 5 months, had recurrent epistaxis, and the coagulation function examination showed that activated partial thromboplastin time (APTT) was significantly prolonged. Further laboratory examinations showed that the prolonged APTT was not immediately corrected in the APTT correction test, with positive lupus anticoagulant and low prothrombin activity. The boy was diagnosed with hypoprothrombinemia-lupus anticoagulant syndrome. The condition was improved after treatment with glucocorticoid, immunoglobulin, and vitamin K1. The boy has been followed up for 6 months, and no epistaxis was observed. Prothrombin activity returned to normal, and lupus anticoagulant remained positive. This is a relatively rare disease, and for patients with bleeding symptoms and coagulation disorders, it is recommended to perform the tests such as APTT correction test, lupus anticoagulant testing, and coagulation factor dilution test, which can improve the detection rate of this disease, so as to achieve early diagnosis, provide rational treatment in the early stage, and improve the prognosis.

Coagulative dysfunction is frequently observed among patients with extranodal nasal-type natural killer/T cell lymphoma (NKTCL) in our clinical practice. However, the true prognostic value of coagulation factors in patients with NKTCL has not been evaluated systemically. Data for patients with stage I/II NKTCL who were treated in the Cancer Hospital, Chinese Academy of Medical Sciences, from January 2008 to January 2019 were collected retrospectively. The patients enrolled in this study were initially diagnosed as having early-stage disease. The patients' baseline characteristics and pretreatment laboratory tests for coagulation function, including fibrinogen (FIB) and D-dimer (D-D), were reviewed and analyzed. The influence of coagulative factors on the responses and prognosis of patients with early-stage NKTCL was evaluated. Among 394 patients assessed, 154 were included in this study. Abnormal coagulation function was found in nearly half of the patients (48.1%). Univariate analysis showed that reduced complete remission (CR) was associated with elevated D-D (P = 0.001) and elevated FIB levels (P = 0.006). The D-D level was demonstrated as associated with unfavorable progression-free survival (PFS) (P = 0.003) and overall survival (OS) (P = 0.002). Multivariate analysis indicated that an elevated D-D level was an independent factor for poor clinical response (P = 0.019), PFS (P = 0.046), and OS (P = 0.024). Elevated pretreatment levels of coagulation factors, especially D-D and plasma FIB, are unfavorable predictors for clinical response, OS, and PFS in early-stage NKTCL.

BACKGROUND: Early diagnosis is important to lower the mortality rate of acute fatty liver of pregnancy (AFLP). The Swansea criteria is commonly used to diagnose AFLP, but some terms could only be reached when symptoms and signs have progressed, or are not efficient in clinical practice. Therefore, it is necessary to select cost effective tests to simplify and facilitate early suspicion of acute fatty liver of pregnancy. METHODS: This is a retrospective study of 28,800 medical records at the Second Xiangya Hospital from 2009 to 2015, including 41 patients with AFLP and 172 other diseases that could show similar symptoms to AFLP. The evaluated variables included past history of liver diseases, blood pressure, gastrointestinal symptoms, blood count, liver function test, coagulation function test and blood sugar test. The sensitivity, specificity, positive predict value and negative predict value were calculated for models in diagnosing AFLP. RESULTS: The significant variables associated with AFLP included gastrointestinal symptoms, blood pressure > 140/90 mmHg, aminotransferase> 42 IU/l, total bilirubin> 0.8 mg/dl, total bilirubin acid> 10.0 µmol/L, activated partial prothrombin time(APTT) > 34 s, prothrombin time(PT) > 14 s, white blood cells> 11 *106/l and blood sugar< 72 mg/dl. Gastrointestinal symptoms +aminotransferase +bilirubin +bile acid +APTT/PT showed 97.6% sensitivity and 97.1% specificity to diagnose AFLP. Adding blood pressure, blood sugar or white blood cells decreased the accuracy of the statistical model. CONCLUSIONS: Application of a statistical model including maternal symptoms, biochemical and haematological parameters has high diagnostic accuracy for earlier identification of AFLP. However, this finding needs to be tested in another cohort to determine whether this statistical model has the same performance.

OBJECTIVE: To explore the effect of remote ischemic conditioning (RIC) on blood coagulation function and cerebral blood flow in patients with aneurysmal subarachnoid hemorrhage. PATIENTS AND METHODS: According to inclusion and exclusion standards, from October 2017 to June 2018, 30 consecutive patients of aneurysmal subarachnoid hemorrhage admitted to Intensive Care Unit, Department of Neurosurgery at Xuanwu Hospital, were given remote ischemic conditioning 5 times intervention to each patient within 7 days, and blood coagulation function testing, including prothrombin activity (PTA), prothrombin time (PT), activated partial prothrombin time (APTT), fibrinogen (Fib), D-dimer, and thromboelastogram (TEG, including R, K, Angle, MA, EPL, LY30, A, CI, G, and A30) were performed for each patient before and after the RIC intervention, as well as venous ultrasound monitoring before and after the RIC intervention for detection of deep vein thrombosis (DVT). Transcranial Doppler evaluation (TCD), including cerebral blood flow of bilateral ACA, MCA, PCA and intracranial segments of VA, as well as BA and the ratios of MCA cerebral blood flow/terminal segment of ipsilateral ICA cerebral blood flow, was performed before and after RIC intervention; and fresh infarction was evaluated by head CT or MRI recheck after RIC intervention. Thirty cases without RIC intervention of matched age, gender, and Hunt Hess grade with aneurysmal subarachnoid hemorrhage were selected to compare coagulation function and cerebral blood flow using TCD with RIC group. RESULTS: (1) Comparing the data before and after the RIC intervention, there was no significant difference for APTT, Fib, and D-dimer (P > 0.05), while PTA decreased and PT increased slightly after intervention as well as INR (P < 0.05) but all still in normal reference values. (2) Comparing the data before and after the RIC intervention, within TEG parameters, only the R value increased with significant difference (P < 0.05) but still in normal reference value, while K, Angle, MA, EPL, LY30, A, CI, G, and A30 had no significant difference (P > 0.05). (3) Comparing the data before and after the RIC intervention, DVT was not detected on the pressurized limbs of patients. (4) Comparing the data before and after the RIC intervention, the cerebral blood flow of bilateral MCA, L-ACA, L-VA, and BA increased (P < 0.05), while the elevation ranges were all in 25%, and the other parameters showed no significant difference. (5) Head CT or MRI showed no fresh cerebral infarction after the RIC intervention. (6) Compared with the group without RIC intervention, the coagulation function and the cerebral blood flow evaluated by TCD of the RIC group showed no statistical difference (P > 0.05) except APTT and D-dimer decreased after RIC but still in normal reference values. CONCLUSION: RIC showed no obvious effect on blood coagulation function and cerebral blood flow in patients with aneurysmal subarachnoid hemorrhage both after the intervention and compared with the non-intervention group. DVT was not detected on the pressurized limbs of patients and no fresh cerebral infarction was detected. This preliminary study confirmed the safety of RIC on blood coagulation function and cerebral blood flow in patients with aneurysmal subarachnoid hemorrhage, and the application of RIC on patients with aneurysmal subarachnoid hemorrhage needs further study to confirm and validate the safety and effectiveness.

BACKGROUND: Gestational diabetes mellitus (GDM) is characterized as glucose intolerance of any degree that begins or first diagnosed during pregnancy. It possesses a higher risk of haemorrhage, which may be caused by the coagulation dysfunction. However, there has been no study focus on how coagulation state changes in the progress of GDM pregnancy. Our study is aimed to assess the association of coagulation function and haemorrhage in GDM. METHODS: A total of 662 subjects (273 from a population-based study and 389 from a prospective cohort study) were selected to measure mean platelet volume (MPV), platelet distribution width (PDW), platelet (PLT), thrombocytocrit (PCT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and fibrinogen (FIB). All pregnant individuals were divided into normal glucose tolerance (NGT) controls and GDM patients diagnosed between the 24th and 28th weeks of gestation. RESULTS: Compared with NGT controls, GDM females showed shortened PT, shortened APTT, and increased blood FIB levels, while the platelet parameters MPV, PDW, PLT, and PCT remained unchanged in mid-pregnancy. By late pregnancy, the platelet parameters MPV, PDW, and PCT were increased in the GDM group compared with the NGT group, while PT and APTT were unchanged. CONCLUSIONS: The GDM group was hypercoagulable compared with the NGT group rather than hypocoagulable as predicted, but still within the normal range. Therefore, our findings demonstrate that the variation degree of coagulation function is not responsible for extra risk of hemorrhage in GDM, and prevention of hemorrhage should focus on other causes.

OBJECTIVE: The aim of the study is to examine the association between Intraoperative cell salvage (ICS), allogeneic blood transfusion (ABT) and coagulation function in obstetrics. METHODS: A total of 486 pregnant women undergoing cesarean delivery, of whom 157 were enrolled in this retrospective study. Patients were divided into ICS group (n = 101, ICS used during operation) and control group (n = 56, ICS not used during operation). Clinical data, including plasma prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib) and thrombin time (TT) levels, were collected from all patients preoperatively (within 12-24 h) and postoperatively (within 6-12 h) and analyzed by t test, two-way repeated-measures ANOVA and Spearman's correlation. RESULTS: The use of ICS is associated with lower requirement rate for ABT (P < .001), while the blood loss was similar between the two groups (P = .990). Mean volume of ICS transfusion was 432.65 mL. Compared to preoperative values, the postoperative PT and APTT levels were significantly increased, while Fib was decreased in the two groups (all P < .01). No significant difference in coagulation function was observed between groups in preoperative and postoperative phase (P > .05). Furthermore, PT, APTT and TT after surgery were not correlated with the transfused volume of salvaged blood (P > .05) while the levels of Fib were negatively correlated with the volume (P < .01). In addition, there were no transfusion reactions in both two groups. CONCLUSIONS: Intraoperative cell salvage is correlated with reduced allogeneic blood requirements but did not impair blood coagulation significantly in patients undergoing cesarean delivery.

Objective: To explore the influence of laparoscopic radical gastrectomy on patients'immune functions, coagulation functions and prognoses. Methods: Fifty-eight patients with gastric cancer who underwent laparoscopic radical gastrectomy (laparoscopic group) and 40 patients with gastric cancer who underwent traditional open surgery (traditional group) in Henan People's Hospital from May 2016 to May 2018 were selected as the subjects. The immune function and coagulation function were compared between the two groups before and after operation. The prognoses of patients underwent laparoscopic radical gastrectomy and the influencing factors were analyzed. Results: Three days after operation, the CD4(+) level and CD4(+) /CD8(+) ratio in laparoscopic group were (29.78±3.58)% and (1.01±0.18), higher than (27.23±3.47)% and (0.93±0.14) in control group (P<0.05). Three days after operation, the activated partial thromboplastin time (APTT) in laparoscopic group was (26.55±2.56) seconds, shorter than (27.86±2.73) seconds in traditional group, while the levels of fibrinogen (FIB) and D-dimer were (4.24±0.84) g/L and (377.91±47.19) µg/L, higher than (3.88±0.75) g/L and (330.28±45.11) µg/L in traditional group (P<0.05). The 5-year survival rate was 77.5% in traditional group and 72.4% in laparoscopic group, without significant difference (P>0.05). Multivariate analysis showed that lymph node metastasis was the independent risk factor for prognosis of laparoscopic radical gastrectomy (P<0.05). Conclusions: Laparoscopic radical gastrectomy can effectively reduce postoperative immunosuppression, but affect postoperative coagulation function. Lymph node metastasis is closely related to the prognosis of patient with gastric cancer. The patient's condition should be comprehensively evaluated before and after operation to determine whether the laparoscopic operation is suitable, for reducing postoperative complications and improving the prognosis.

Objective: To measure the coagulation function of patients with adenomyosis so as to explore its relationship with increased menstrual amount and its clinical significance. Methods: From January 2014 to May 2019, clinical data of patients with hysterectomy in which 111 pathologically diagnosed adenomyosis (case group) and 115 with uterine myoma (control group) in Peking University First Hospital were retrospectively analyzed. The changes in coagulation function of the two groups were compared, and the correlation between coagulation and uterine volume in the adenomyosis group was analyzed. Results: (1) The activated partial thromboplastin time (APTT) was longer in the adenomyosis group than that in the uterine myoma group [(30.4±3.1), (29.6±2.5) s, respectively; P<0.05], while the thrombin time (TT) was shorter than that in the control group [(14.2±1.2), (14.6±1.0) s, respectively; P<0.05]. (2) According to the results of the Pearson correlation test, there was a positive correlation between prothrombin time (PT; r=0.135, P=0.042) and fibrinogen (FIB-C; r=0.139, P=0.036). (3) Platelet counts were higher in the anemia group of adenomyosis than that in the non-anemia group [(323±79)×109/L, (274±56)×109/L, respectively; P<0.05]. (4) FIB-C in non-anemia group of adenomyosis was lower than non-anemia group of uterine myoma [(2.8±0.5), (3.0±0.6) g/L, respectively; P<0.05], the anemia group of adenomyosis shortened TT compared with the anemia group of uterine myoma [(14.4±1.2), (15.2±0.9) s, respectively; P<0.05]. Conclusion: Patients with adenomyosis have abnormal coagulation function, which may be related to the increase amount of menstruation, and anemia may also be involved in coagulation disorders.

OBJECTIVE: To discuss clinical effect of different dosage of rituximab combined with cyclophosphamide in treatment of refractory immune thrombocytopenia (rITP). METHOD: This study was conducted at Department of Hematopathology in XX Hospital from January 2016 to January 2018. In this study. Seventy-eight patients with rITP were selected as the objects, divided into observation group (39 cases) and control group (39 cases) according to random number table. Patients in the control group were treated with conventional rituximab and cyclophosphamide, while the observation group received low-dose rituximab. The same amount of cyclophosphamide was used in the two groups. The statistics of clinical effect, recurrence rate, untoward effect and Laboratory inspection of both groups were made before and after the treatment. RESULTS: Compared with the control group, the total occurrence rate of side effects in the observation group decreased significantly; the level of IgM and CD20+ in the observation group also decreased significantly, while. The level of IgA, IgG, CD3+ and CD4+ rose significantly (P<0.05). The differences in the level of Th1, TNF-a, IL-18 and Sc5b-9 had statistical significance before and after the treatment (P<0.05). CONCLUSION: Rituximab combined with cyclophosphamide has the definite curative effect on rITP. The small dosage of rituximab combined with cyclophosphamide has higher clinical safety in the treatment.
RESUMO
OBJECTIVES: To explore the significance of coagulation and immune function indicators in clinical diagnosis and treatment of coronavirus disease 2019 (COVID-19). METHODS: All patients with COVID-19 diagnosed and treated in First People's Hospital of Yueyang from January to March 2020 were enrolled. The general data of patients were collected. The patients were assigned into a light group (n=20), an ordinary group (n=33), a severe group (n=23), and a critically severe group (n=7) according to the severity of the disease. Coagulation and immune function indicators of each group were compared, and the relevance of coagulation and immune function indicators was analyzed. RESULTS: The age of COVID-19 patients in Yueyang City was mainly between 45 and 65 years old. There was a significant difference in the coagulation function and immune-related indicators in each group of patients (all P<0.05). CONCLUSIONS: There are some abnormalities in coagulation and immune function in patients with COVID-19, which possess significance for clinical diagnosis and treatment of the disease.
