ABSTRACT
Objective: To investigate the effect and safety of tranexamic acid sequential rivaroxaban on perioperative blood loss and preventing thrombosis for elderly patients during lumbar interbody fusion (LIF) with a prospective randomized controlled study. Methods: Between April and October 2019, the elderly patients with lumbar degenerative diseases requiring LIF were included in the study, among which were 80 patients met the selection criteria. According to the antifibrinolysis and anticoagulation protocols, they were randomly divided into a tranexamic acid sequential rivaroxaban group (trial group) and a simple rivaroxaban group (control group) on average. Finally, 69 patients (35 in the trial group and 34 in the control group) were included for comparison. There was no significant difference in general data ( P>0.05) such as gender, age, body mass index, disease duration, diseased segment, type of disease, and preoperative hemoglobin between the two groups. The operation time, intraoperative blood loss, drainage within 3 days after operation, perioperative total blood loss, and proportion of blood transfusion patients were compared between the two groups, as well as postoperative venous thrombosis of lower extremities, pulmonary embolism, and bleeding-related complications. Results: The operations of the two groups completed successfully, and there was no significant difference in the operation time ( P>0.05); the intraoperative blood loss, drainage within 3 days after operation, and perioperative total blood loss in the trial group were significantly lower than those in the control group ( P<0.05). The proportion of blood transfusion patients in the trial group was 25.71% (9/35), which was significantly lower than that in the control group [52.94% (18/34)] ( χ2=5.368, P=0.021). Postoperative incision bleeding occurred in 4 cases of the trial group and 3 cases of the control group, and there was no significant difference in bleeding-related complications between the two groups ( P=1.000). There was 1 case of venous thrombosis of the lower extremities in each group after operation, and there was no significant difference in the incidence between the two groups ( P=1.000). Besides, no pulmonary embolism occurred in the two groups. Conclusion: Perioperative use of tranexamic acid sequential rivaroxaban in elderly LIF patients can effectively reduce the amount of blood loss and the proportion of blood transfusion patients without increasing the risk of postoperative thrombosis.
ABSTRACT
Objective To investigate the effect of muscle function on structural stress in patient with lumbar disc herniation (LDH), by observing the stress changes in LDH lumbar-pelvis finite element model loaded with muscle force. Methods One normal healthy volunteer and one LDH patient were selected. Their CT data were collected to establish two corresponding normal and LDH lumbar-pelvis finite element models, and their gait data were also simultaneously collected to drive the AnyBody musculoskeletal model. The muscle force around the lumbar and pelvis as well as the hip-joint force were obtained as the loading condition. Self-loading of the normal and LDH model as well as the normal model loaded with LDH muscle forces were conducted seperately. Then the stress changes in L4 and L5 intervertebral discs and sacroiliac joints under two above loading conditions were compared. Results The stress curve of normal model loaded with LDH muscle force showed a unimodal stress curve, instead of a bimodal curve, and such trend of stress-time curve was as same as the trend of the LDH model during self-loading. But the stress difference in L4 and L5 intervertebral discs and sacroiliac joint of the normal model loaded with LDH muscle force was smaller than that in the LDH model during self-loading. Conclusions Abnormal muscle function of LDH could lead to abnormal joint stress of the intervertebral discs and sacroiliac joint. Structural imbalance itself could lead to stress imbalance, and muscle as a driving factor was an important cause of anomaly structural dynamic stress, thus leading to abnormal joint motion patterns. Therefore, attention should be paid to assessment of the imbalance of peripheral muscle function in clinical treatment of LDH.
ABSTRACT
Objective To evaluate different inflammation markers for predicting the risk of acute kidney injury (AKI) in sepsis patients. Methods A retrospective observational study was conducted. The adult patients with sepsis for more than 24 hours admitted to intensive care unit (ICU) of Beijing Friendship Hospital, Capital Medical University from March 1st, 2010 to November 1st, 2017 were enrolled. Inflammatory markers such as white blood cell count (WBC), erythrocyte sedimentation rata (ESR), neutrophil and lymphocyte ratio (NLR), C-reactive protein (CRP), procalcitonin (PCT), etc. were collected at ICU admission. The patients were divided into different groups according to the 24-hour AKI, and subgroup analysis was conducted according to the criteria of the Global Renal Disease Prognostic Organization (KDIGO)-AKI staging. The receiver operating characteristic curve (ROC) was plotted with statistically significant inflammatory markers to assess the predictive value of AKI for patients with systemic infection. Results A total of 753 patients with sepsis were enrolled. 405 AKI patients were diagnosed within 24 hours, with a prevalence of 53.8%. There were 118 cases (15.7%) in AKI stage 1, 48 cases (6.4%) in stage 2 and 239 cases (31.7%) in stage 3. PCT in AKI group was significantly higher than that in non-AKI group [μg/L: 4.98 (1.51, 32.75) vs. 3.00 (0.37, 11.40), P < 0.01]. PCT of AKI stage 2 group was significantly higher than that of AKI stage 1 and 3 groups [μg/L: 27.86 (4.80, 37.26) vs. 3.00 (0.98, 16.10), 4.98 (1.51, 42.55), both P < 0.01]. Although ESR in AKI group was lower than that of non-AKI group (mm/1 h: 45.25±37.42 vs. 52.28±34.89, P < 0.01), there was no significant difference among the subgroups. CRP in AKI group was slightly higher than the non-AKI group [mg/L: 96.00 (42.20, 160.00) vs. 73.60 (21.01, 157.50)], but the difference was not statistically significant (P > 0.05). There was no significant difference in WBC or NLR between AKI group and non-AKI group. It was shown by ROC curve analysis that the area under ROC curve (AUC) of PCT in predicting the occurrence of septic AKI was 0.619, with the 95% confidence interval (95%CI) of 0.545-0.689 (P < 0.01). When the cut-off value of PCT > 0.4 μg/L, the sensitivity was 94.2%, the specificity was 26.5%, the accuracy was 64.2%, the positive predictive value was 61.6%, and the negative predictive value was 78.6%. Conclusion PCT could be a marker to predict AKI with sepsis patients.
ABSTRACT
Objective To explore the biomechanical mechanisms of correlation between lumbar disc degeneration and sacroiliac joint disorder though investigating the biomechanical characteristics of lumbar disc degeneration with sacroiliac joint disorders.Methods One normal healthy volunteer and two patients with lumbar disc herniation and sacroiliac joint disorders (one was with sacrum disorders and the other was with ilium disorders) were selected.Their CT data were collected to establish three corresponding lumbar-pelvis finite-element models,and their gait data were also simultaneously collected to drive the AnyBody musculoskeletal model.The muscle force around the lumbar and pelvis as well as the hip joint force were acquired as loading condition for finite element analysis.The stress changes in L4 and L5 intervertebral discs and sacroiliac joints of the patients and normal volunteer were compared.Results There was no significant difference in the stress of the two sides of L4,L5 disc and two sacroiliac joints in normal model,with a bimodal stress curve.However,in the models of sacrum disorders and ilium disorders,the bimodal stress curve peaks changed,even disappeared.The peak stress differences in left and right side of L4 disc were 0.55 MPa and 0.80 MPa,respectively,the peak stress differences in left and right side of L5 disc were 4.05 MPa and 2.08 MPa,respectively,and the peak stress differences in left and right side of sacroiliac joints were 0.96 MPa and 3.32 MPa,respectively.Conclusions The lumbar disc degeneration with sacroiliac joint disorder leads to the tilt of the body loading line,and sacroiliac joint disorder can aggravate the imbalances of stress on the body sides.The impact of sacroiliac joint dysfunction cannot be ignored in the treatment of lumbar disc herniation.
ABSTRACT
Objective To identify the threshold of percentage of body fat (BF％) associated with diabetes mellitus,hypertension and dyslipidemia in an elderly Chinese population.Methods An individual was considered as a subject if they exhibited any one of the three cardiovascular disease risk factors:diabetes mellitus,hypertension or dyslipidemia.A total of 1 140 subjects were recruited from the Physical Examination Center of Tianjin Hospital,China (male 511,female 629,aged ≥60 years).Questionnaire interview,physical examination,body composition measurement,blood biochemistry measurement,muscle strength measurement and other measurements were performed for each subject.Receiver operating curves (ROC) were created to determine the optimal percentage of body fat cutoff points,with the presence of diabetes mellitus,hypertension or dyslipidemia as outcome variable.Results The percentage of subjects with at least one of the following conditions (diabetes mellitus,hypertension or dyslipidemia) was 62.8％ for men and 73.9％ for women.Increased percentage of body fat was associated with an increased occurrence of diabetes mellitus,hypertension or dyslipidemia in the elderly,particularly among women.The ROC curve shows that the threshold of fat percentage in men and women was 28.2％ and 36.6％,respectively.Conclusion The risks of diabetes,hypertension and dyslipidemia is closely related to elevated body fat mass in the elderly.The percentage of body fat mass is an important indicator of obesity,threshold of BF ％ can provide reference for clinical obesity intervention in elderly patients.It also can provide reference for the treatment and prevention of cardiovascular disease.
ABSTRACT
Objective To analyze the characteristics of change in plasma cholesterol level in patients with sepsis, and to explore its relationship with prognosis and its clinical significance. Methods A retrospective analysis was conducted. 568 patients with sepsis admitted to Department of Critical Care Medicine of Beijing Friendship Hospital Affiliated to Capital Medical University from August 2013 to August 2015 were enrolled, and 475 patients without sepsis hospitalized in the same period served as the control. The basic clinical data of the two groups were collected, and the results of blood fat and biochemical parameters were compared. The patients with sepsis were divided into death group and survival group, and risk factors influencing the prognosis of patients with sepsis were analyzed with multivariate logistic model regression analysis. Results Compared with non-sepsis patients, the levels of plasma total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) in the patients with sepsis were significantly lower [TC (mmol/L): 2.5±1.2 vs. 3.4±1.4, t = 4.274, P = 0.021; HDL-C (mmol/L): 1.6±0.9 vs. 2.5±0.8, t = 3.413, P = 0.018], and that of low density lipoprotein cholesterol (LDL-C) showed no statistically significant difference (mmol/L: 1.9±0.9 vs. 2.1±0.9, t = 0.749, P = 0.614). In the patients with sepsis, the patients in death group (n = 227) were older than those of the survival group (n = 341, years: 74.3±15.5 vs. 65.5±17.5, t = 4.037, P = 0.012), serum creatinine (SCr) was higher than that of survival group (μmol/L: 251.0±115.6 vs. 167.4±108.7, t = 3.254, P = 0.023), the levels of plasma TC, HDL-C and LDL-C were significantly lower than those of survival group [TC (mmol/L): 2.2±1.6 vs. 2.9±1.1, t = 3.057, P = 0.023; HDL-C (mmol/L): 1.4±0.8 vs. 1.9±0.8, t = 4.692, P = 0.016; LDL-C (mmol/L): 1.7±0.7 vs. 2.0±0.8, t = 2.541, P = 0.038]; there was no significant difference in the proportion of male, body mass index (BMI), based disease, intensive care unit (ICU) hospitalization time, the severity of the disease and other biochemical indexes between two groups. With single factor analysis with indicators of statistical significance as a covariate into binary logistic regression equation, the results show that age was the risk factor of death in patients with sepsis [odds ratio (OR) = 1.024, 95% confidence interval (95%CI) = 1.010-1.048, P = 0.009], and TC was the protective factor on the prognosis of patients with sepsis (OR = 0.747, 95%CI = 0.682-0.811, P = 0.013). Conclusions Plasma cholesterol levels in patients with sepsis were significantly lowered, and the levels in death group was significantly lower than that in the survival group. TC may be used as a clinical indicator to assess the outcome of patients with sepsis.

ABSTRACT
Objective To explore the feasibility of using contralateral breast as the donor for immediately breast reconstruction or chest wall defect repair after mastectomy in breast cancer patients. Methods From Jul. 2013 to Mar. 2016, contralateral breast fat flap was used as the donor for 8 breast cancer patients with immediate autologous non-microsurgical breast reconstruction or chest wall defect repair after mastectomy. All participants in this study received preoperative oncological screening with ultrasound, mammography, and magnetic resonance imaging which revealed the absence of pathological abnormalities in the donor breast. Results Among the 8 pa-tients, 4 patients underwent immediate breast reconstruction and 4 received chest wall defect repair. Only 1 pa-tient undergoing breast reconstruction had minor complications with little or no effect on the final outcome. No patient undergoing chest wall defect repair had postoperative complications. The functional and aesthetic out-comes were very satisfactory. Regular follow-ups were from 3 to 34 months with no recurrence found up to the present. Conclusions This article presents the first case for immediately breast reconstruction or chest wall de-fect repair using contralateral breast as the donor. The surgical method has some complications but with good aesthetic outcomes, which can be an option for breast cancer patients with hypertrophic and ptotic breast.
ABSTRACT
OBJECTIVE:To investigate the effects and safety of erythropoietin on nerve function and brainstem auditory evoked potential in the preterm children with brain damage. METHODS:46 preterm children with brain damage were randomly di-vided into treatment group and control group,with 23 cases in each group. Control group received conventional symptomatic treat-ment as respiratory support,nutritional support,vitamin K supplement and ganglioside. Treatment group was additionally given rhE-PO for injection (CHO cell) 500 IU/kg hypodermically,3 times a week,on the basis of control group. Both group received 3-4 weeks of treatment continuously. MDI,PDI,the content of serum nerve injury factor(NSE,S-100β),latent period and peak inter-val of brainstem auditory evoked potential were compared between 2 groups before and after treatment,and the occurrence of ADR was observed in 2 groups. RESULTS:There was no statistical significance in MDI,PDI,the content of serum nerve injury mole-cule,latent period and peak interval of brainstem auditory evoked potential between 2 groups before treatment (P>0.05). After treatment,MDI and PDI of 2 groups increased significantly,while the content of serum nerve injury factor,latent period and peak interval of brainstem auditory evoked potential decreased significantly;the treatment group was better than the control group,with statistical significance (P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Erythropoietin can significantly im-prove intelligence development,protect the damaged nerve cells and auditory nerve pathways with good safety.

ABSTRACT
AIM: To investigate the protective effect of the bone marrow cells transfected with human multidrug resistance gene (MDR1) on the reconstruction of murine hematopoietic function.METHODS: The mononuclear cells of the bone marrow from donors, BALB/C mice, treated with 5-Fu previously, were isolated and transfected with human multidrug resistance gene in vitro , then transplanted to the tertiary recipients. After lethal irradiation(8.5 Gy) and bone marrow transplantation, the recipients were selected with Taxol 7 mg/kg intraperitoneal injection, VCR 5 mg/kg or DNA 5 mg/kg intravenous injection. The survival rate and blood pictures of mice as well as the integration and expression of target gene MDR1 were studied. RESULTS: The lethal irradiated murine hematopoietic function could be reconstructed and protected from toxicity of high doses Taxol, VCR and DNR selection after reinfusing the hematopoietic progenitor cells containing human multidrug resistance gene (MDR1). The survival rate and survival time of experimental mice were higher than that in the control group. The integration and expression of MDR1 gene in recipients were confirmed by PCR, RT-PCR and FCM. CONCLUSION: The integration and expression of human multidrug resistance gene in recipients may play an important role in the reconstruction and protection of murine hematopoietic function.
