ABSTRACT

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

ABSTRACT

Traumatic brain injury (TBI) has been recognized as a risk factor for developing dementia. Currently, around 69 million people worldwide suffer from TBI each year, while the overall incidence of TBI among Chinese residents is on a rapid rise. Such a large population of TBI patients may lead to a future surge in the number of dementia patients, bringing heavy burdens on families and societies. However, it seems to be suggested by numerous studies that not all TBI patients are associated with an increased risk of dementia. Dementia can result in disability as well as interfere with caregivers ′ normal lives. Therefore, it will be significant to clarify the relationship between TBI and dementia as well as explain the process of onset and development of post-TBI dementia. In this study, the authors summarize post-TBI dementia from aspects of influencing factors and pathogenic mechanisms, so as to provide relevant references for related studies, therapy, and prophylaxis of post-TBI dementia.

ABSTRACT

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.

ABSTRACT

Objective To observe the effects of curcumin on pulmonary fibrosis and functions on paraquat (PQ)-challenged rats, and investigate the possible mechanism. Methods 108 SPF Wistar rats were divided into three groups according to random number sheet: normal saline (NS) control group, PQ model group and curcumin-treatment group. The rats in each group were subdivided into three subgroups according to different time points (3, 7, 14 days), with 12 rats in each subgroup. PQ-challenged models were reproduced by intragastrical administration of PQ solution 50 mg/kg, and those in NS control group were given the equal volume of NS. After 30 minutes, the rats in curcumin-treatment group were given 200 mg/kg of curcumin by intraperitoneal injection, and those in NS control group and PQ model group were given the equal volume of NS. At 3, 7, 14 days, the tidal volume (VT) was examined, and the blood was drawn from femoral artery for blood gas analysis. Then the rats were sacrificed and the lung tissues were harvested, the hydroxyproline (Hyp) content was measured by alkaline hydrolysis; the expression of transforming growth factor-β1 (TGF-β1) was determined by immuno-histochemistry; the distribution and the change of the pulmonary collagen fiber were observed after Masson staining. Results After exposure to PQ, the VT and arterial partial pressure of oxygen (PaO2) were decreased gradually, and the levels of Hyp and TGF-β1 were increased gradually, reaching the trough or the peak at 14 days, which were significantly lower or higher than those in NS control group [14-day VT (mL):1.52±0.33 vs. 2.81±0.47, 14-day PaO2(kPa): 5.87±0.95 vs. 14.15±1.02, 14-day Hyp (μg/mg): 3.12±0.06 vs. 1.14±0.05, 14-day TGF-β1 (integral A value): 29.72±4.27 vs. 4.15±0.52, all P < 0.01]. After intervene of curcumin, the parameters were significantly improved as compared with those of PQ model group [14-day VT (mL): 2.34±0.19 vs. 1.52±0.33, 14-day PaO2(kPa): 10.23±1.01 vs. 5.87±0.95, 14-day Hyp (μg/mg): 2.31±0.04 vs. 3.12±0.06, 14-day TGF-β1 (integral A value): 15.46±2.89 vs. 29.72±4.27, all P < 0.01]. It was shown by Masson staining that in PQ model group, with the PQ-poisoned time prolonging, diffused pulmonary fibrosis and a large number of collagen deposition were observed gradually, and the most serious collagen deposition was observed at 14 days; after intervene of curcumin, pulmonary fibrosis was alleviated significantly at different time points as compared with the PQ model group. Conclusion Curcumin can enhance the pulmonary function by reducing the deposition of collagen fiber and inhabiting pulmonary fibrosis of PQ-poisoned rats.

ABSTRACT

BACKGROUND:Core decompression and autogenous bone grafts are widely used in treatment of early avascular necrosis of femoral head. According to the report, the success rate of this therapy has obvious difference;the reasons may be related to inaccurate puncture location and secondary damnification of repeated puncture. OBJECTIVE:To reconstruct three-dimensional model of femoral head necrosis by Mimics software for reappearance of lesions in the necrotic area to realize measurement of necrotic area of the femoral head and estimation of its volume. METHODS:We restructured images by using multi-slice spiral CT Syngommvvp VE23A workstation, Inspace software and NeuroDSA software. Hip CT data in DICOM format were imported into Mimics 13.0 software systems. Necrotic area of the femoral head was reconstructed with Mimics SimuIation software to truly reproduce the integrated form, scope and stereochemical structure of the necrotic area so as to achieve the measurement of the necrotic area of the femoral head and the volume estimation. We designed the best core decompression channel, simulated core decompression surgery, so that the patients could refer to the best simulated decompression path in the operation of core decompression. RESULTS AND CONCLUSION:(1) Among 36 patients (48 hips) with avascular necrosis of femoral head, there were phase I in 8 hips, accounting for 17%, phase II in 28 hips, accounting for 58%, and phase III in 12 hips, accounting for 25%. (2) The volume of necrotic area was (1 475.48±647.342) mm3 in the phase I, (4 571.77±2 344.55) mm3 in the phase II, and (4 836.46±2 969.33) mm3 in the phase III. (3) We simulated the core decompression based on the radius of the sphere of the necrotic area as parameter in the Mimics Simulation software module, and then completely cleared the necrotic area. (4) Surgery can more clearly understand information and stereochemical structure of the necrotic area with Mimics software to simulate the core decompression. It is the theoretical basis of operation.

ABSTRACT

BACKGROUND:As the high proliferation and low apoptosis of the bone marrow in polycythemia vera patients, hematopoietic stem cels transplanted into NOD/SCID mice can differentiate into erythroid cels, but whether hematopoietic stem cels transplantation could improve the hematopoietic function of aplastic anemia mice is not yet reported. OBJECTIVE:To investigate whether transplantation of bone marrow mononuclear cels with JAK2V617F mutation from polycythemia vera patients can influence hematopoietic reconstruction in aplastic anemia mice. METHODS:Severe aplastic anemia mouse models were established by using recombinant human interferon-γplus busulfan, and then, these mouse models were randomly divided into experimental group (n=10) and control group (n=10). Bone marrow mononuclear cels isolated from polycythemia vera patients with positive JAK2V617F mutation were transplanted into the mice in the experimental group via tail vein at 5 days after drug withdrawal.The same volume of normal saline was administered to the control group. Routine peripheral blood test, morphology of bone marrow cels, bone marrow biopsy, and percentage of CD45+ cels in the peripheral blood and marrow were determined at 14 days after transplantation. RESULTS AND CONCLUSION: At 14 days after transplantation, pancytopenia occurred in the experimental group, bone marrow smears showed scattered lymphocytes and hematopoietic progenitors, and bone marrow biopsy presented that hematopoietic tissues were reduced and a smal amount of granulocyte cels and erythroblasts could be seen, but megakaryocytes were rare. In contrast to the control group, there was no improvement in the hematopoietic function of mice in the experimental group. CD45+ cels were detectable in the peripheral blood and bone marrow in the experimental group, but not in the control group; and a higher percentage of CD45+ cels was measured in the bone marrow than in the peripheral blood of experimental group mice. Experimental findings indicate that bone marrow mononuclear cels from polycythemia vera patients with positive JAK2V617F mutation can be engrafted into aplastic anemia mice, but cannot improve the hematopoietic function of mice.

ABSTRACT

BACKGROUND:It is important to establish an ideal mouse model of severe aplastic anemia for investigating the mechanism and finding new therapies for aplastic anemia. OBJECTIVE:To establish a severe aplastic anemia mouse model by using recombinant human interferon-γand busulfan. METHODS:Sixty healthy Kunming female mice were randomly divided into two groups:model group (n=50) and control group (n=10). The model group was given recombinant human interferon-γat a dose of 1×104 U/d by intraperitoneal injection and busulfan at a dose of 18 mg/(kg·d) through stomach feeding for 7 days. The same volume of physiological saline was given to control group. Multi-parameters, including general condition, body weight, blood cellcount, morphology and biopsy of bone marrow were analyzed in two groups. RESULTS AND CONCLUSION:At day 7 after treatment, the weight, white blood cellcount, hemoglobin, blood platelet, reticulocyte count in model group were significantly lower than control group (P<0.05). Bone marrow smears and biopsy of model group showed marked reduction of bone marrow proliferation and increases of percentages of non-hematopoietic cellclusters and adipose tissue. The oil drop and fat vacuole were apparently seen in the model group. Severe aplastic anemia mouse model can be established by using recombinant human interferon-γand busulfan successful y, which is economic, stable and easy to operate.

ABSTRACT

Objective To evaluate the significance of platelet activation and the expression of inter-leukin (IL)-1β in patients with RA. Methods The activation of platelets and the expression of IL-1β in pla-telets in 50 RA patients(22 high-active, 28 mediate/low active ) and 30 normal controls were determined us-ing flow cytometry. Meanwhile, inflammatory indicators such as erythrocyte sedimentation(ESR), C-reactive protein (CRP) and DAS28 were also recorded. T test and correlation analysis were performed. Results The platelet activation in RA group(19.2±4.8) was higher than the control group(9.0±2.9)(t=10.5, P=0.001). The expression of IL-1β in platelets in RA group(41±11) was higher than control group(21±8)(t=9.01, P =0.000) .The platelet activation in high-active RA group(22 ±4) was higher than mediate/low active RA group(17 ±4)(t =3.96,P =0.001). The expression of IL-1β in platelets in high-active RA group(45 ±10) was higher than mediate/low active RA group (38 ±10)(t =2.329,P =0.024). The expression of IL-1β in platelets in RA group was positively correlated with the level of ESR、CRP and DAS28 (r value and P value were 0.576, 0.578, 0.618 and 0.000, 0.000, 0.000 respectively). Conclusion The platelets of patients with RA are activated and may suggest that IL-1β, which may associate with disease activity. Our research suggest that platelet may play a role in the inflammatory process of RA by secreting IL-1β.

ABSTRACT

Objective To investigate the long-term efficacy of nonmyeloablative autologous peripheral blood stem cell transplantation(NAST) to cure refractory autoimmune disease(AD).MethodLong-term follow up of four cases of AD patients with NAST were summarized.The pretreatment regimen was intravenous injection of cytarabin (200 mg· kg-1· d-1 ) and cyclophosphamide (40 mg· kg-1· d-1).The therapeutic effect was evaluated by the change of symptoms and signs and long term complications.Changes of immune function were detected by flow-cytometry.ResultsFive cases of patients had been successfully engrafted.The average time for peripheral leucocytes count to reach 4.0×109/L was 12 days.It needed 10 days for platelets to return to 100×109/L and 22 days for hemoglobin to 120 g/L.Apparent remission of symptoms and signs was observed after transplantation.Lymphocyte subtypes analysis pre- and post- NAST showed that count of CD4+ and the ratio of CD4 +/CD8 + was returned to normal.One patient gave birth to a healthy baby four years after transplantation.Three female patients returned tonormal life. Conclusions Compared with classical myeloablative stem cell transplantation,NAST has a rapid hematopoietic recovery and good long-term therapeutic effect in AD.The quality of life in AD patients treated with NAST is higher than those treated with myeloablative hematopoietic stem cell transplantation.

ABSTRACT

BACKGROUND: Relapse of acute leukemia is possibly correlated with abnormal expression of cellular adhesion molecule-1 (VCAM-1).OBJECTIVE: To observe the level of VCAM-1 in serum and bone marrow stromal cell (MSC) supernatant of patients with relapsed acute leukemia. METHODS: Samples of serum and MSC supernatant were collected from 17 patients with remission-phase and relapse-phase acute leukemia hospitalized in the Department of Hematology, the Fifth Affiliated Hospital of Sun Yat-sen University between June 2006 and March 2008. The levels of VCAM-1 were measured with ELISA in remission and relapse phases.RESULTS AND CONCLUSION: Compared with the remission phase, the VCAM-1 level of serum was significantly increased in the relapse phase (P < 0.05). At 1 and 3 weeks after in vitro culture, the VCAM-1 level in the MSC supernatant was not changed (P > 0.05), but it was significantly increased on the fourth week (P < 0.05). The results demonstrated that VCAM-1 expression of serum and MSC supernatant in the relapse phase was greater than that in the remission phase, suggesting that abnormal expression of VCAM-1 was possibly correlated with relapse of acute leukemia.

ABSTRACT

Objective To discuss clinical effects of early (<48 hours after injury) fraeture exter-nal fixation in treatment of severe traumatic brain injury (TBI) combined with extremity fracture. Meth-ods The study involved patients with no statistical difference in aspects of age, sex, GCS, fracture ,distri-bution and general condition. According to different treatment methods at early stage (<48 hours), the pa-tients with TBI were divided into Group A (early extremity fracture external fixation) and Group B (early extremity fracture traction or cast immobilization). A comparative observation was done on complications in-cluding bedsore, pneumonia and deep venous thrombosis and on duration in ICU, hospitalization, time for fracture healing and mortality in two groups. Results Incidence rate of bedsore, pneumonia, deep ve-nous thrombosis and mortality in Group A was lower than that in Group B (P<0.05), and Group A had shorter time for ICU, hospitalization and fracture healing (P < 0.05). Conclusion For patients with se-vere TBI combined with extremity fracture, early fracture external fixation is more effective to reduce com-plications, shorten the recovery time and reduce mortality, compared with conservative methods.
