Objective To analyze the cause of acute brain swelling,brain encephalocele in brain traumatic injury craniotomy,and the reason,diagnosis and treatment methods of progressive epidural hematoma.Methods The clinical data of 381 patients with brain traumatic injury craniotomy were retrospetively analyzed.Of 318 patients,27cases had progressive epidural hematoma during operation.Results 9 cases died because of functional failure of brain stem,the other 18 cases were all clinically cured.Conclusion If acute brain swelling and encephalocele occured during operation,the cause should be found quickly,especially when there was skull fracture or epidural hematoma on the contralateral brain,the head CT and operation should be taken immediately,and the bulging brain tissue should not be removed blindly,and the skull should not be forced to close,otherwise the prognosis maybe poor.

Objective To observe the efficacy of lamellar hole-associated epiretinal proliferation (LHEP) flap insertion and autologous blood for degenerative type lamellar macular hole (LMH).Methods Retrospective case review.Twenty-eight eyes of 28 patients with LMH were enrolled in this study.There were 2 males (2 eyes) and 26 females (26 eyes).Best corrected visual acuity (BCVA),medical optometry,slit-lamp biomicroscop,indirect ophthalmoscope,spectral domain optical coherence tomography,b-scan ultrasonography and axial length detection were performed on all patients.Logarithm of the minimum angle of resolution (logMAR) was used to calculate visual acuity.There were 10 eyes (35.7％) with degenerative type LMH (flap insertion group) and LHEP.There were 18 eyes (64.3％) with tractional type LMH (general group).The differences of BCVA,AL,horizontal hole diameter from retina and lens state between two groups were not significant (P＞ 0.05).The differences of horizontal hole diameter of internal limiting membrane (ILM),central foveal thickness (CFT) and integrity of ellipsoidal zone between two groups were significant (P＜ 0.05).LHEP flap insertion and autologous blood without ILM peeling were used in eyes of flap insertion group.Vitrectomy combined ILM peeling were used in eyes of general group.The follow-up was ranged from 3 to 14 months.The changes of CFT,central foveal form and logMAR BCVA were observed.Results At latest follow-up,the BCVA of flap insertion group and general group were 0.34±0.27,0.31±0.29;which significantly better than the preoperative BCVA (Z=-3.519,-4.945;P＜ 0.001).The CFT of flap insertion group and general group were (200.10±58.78),(226.61±70.49) μm.There was no difference between pre-and post-operative CFT in eyes of general group (Z=-1.455,P=0.146).There was significant difference between pre-and post-operative CFT in eyes of flap insertion group (Z=-2.798,P=0.005).In flap insertion group,regular recovery of the foveal contour occurred in 9 eyes (90.0％),improvement in 1 eyes (10.0％).In general group,regular recovery of the foveal contour occurred in 10 eyes (55.6％),improvement in 8 eyes (44.4％).The closure rate of LMH were 100％ both in two groups.Conclusion LHEP flap insertion and autologous blood is an effective treatment of degenerative type LMH.

Objective To investigate the role of cyclic GMP-AMP synthase (cGAS),a cytosolic DNA sensor,in regulating innate immune responses induced by reverse transcription intermediate of human T cell leukemia virus type 1 (HTLV-1). Methods (1)ssDNA90,the reverse transcription intermediate of HTLV-1,was transfected into HeLa cells to observe changes in the expression pattern of cGAS in transfected-HeLa cells with immunoblot assay. (2) HeLa cells were firstly transfected with cGAS-encoding plasmid and then ssDNA90 24 hours later. Real-time PCR was used to measure the expression of interferon ( IFN)-β, IFN-gamma-inducible protein 10 ( IP-10 ), regulated on activation, normal T cell expressed and secreted (RANTES) and tumor necrosis factor (TNF)-α. Immunoblot assay was performed to measure phosphorylated interferon regulatory factor 3 (IRF3) and p65. (3)cGAS expression was silenced by siRNA in HeLa and phorbol-12-myristate-13-acetate (PMA)-treated THP1 (PMA-THP1) cells and then ssDNA90 was transfect-ed into these cells 24 hours later. Real-time PCR was used to measure the expression of IFN-β,IP-10,RAN-TES and TNF-α. Immunoblot assay was performed to measure phosphorylated IRF3 and p65. Results Ex-pression of cGAS was increased in HeLa cells after ssDNA90 transfection. Compared with control cells, cGAS-transfected HeLa cells showed increased expression of IFN-β, IP-10, RANTES and TNF-α and en-hanced phosphorylation of IRF3 and p65 after ssDNA90 transfection. Compared with control cells,both HeLa and PMA-THP1 cells with silenced expression of cGAS showed impaired production of IFN-β,IP-10,RAN-TES and TNF-α after ssDNA90 transfection. Moreover,ssDNA90-induced phosphorylation of IRF3 and p65 were decreased after cGAS gene-knockdown. Conclusion cGAS might promote HTLV-1 RTI ssDNA90-in-duced innate immune responses.

Objective To investigate the function and the possible mechanism of cyclic GMP-AMP synthase (cGAS), a DNA sensor, in HeLa cells during human T cell leukemia virus type 1 (HTLV-1) in-fection.Methods HeLa cells were co-cultured with MT2 cells (HTLV-1-positive T cells) and then detec-ted by immunoblot assay to analyze the changes in the expression of cGAS .A hemagglutinin ( HA)-tagged cGAS plasmid was constructed and transfected into HeLa cells .Twenty-four hours after transfection , these cells were co-cultured with MT2 cells for another 24 hours.Immunoblot assay was used to detect the expres-sion of HTLV-1 proteins Tax and p19.Real-time PCR was performed to measure the expression of HTLV-1 Tax, p19, Env, HBZ and px at mRNA level .Immunoblot assay was also used to analyze the phosphorylation of interferon regulatory factor 3 (IRF3) and p65.Expression of interferon (IFN)-β, IFN-gamma-inducible protein 10 ( IP-10 ) , RANTES ( regulated on activation , normal T cell expressed and secreted ) and tumor necrosis factor (TNF)-αwas detected by real-time PCR assay.Results Expression of cGAS was enhanced in HeLa cells after co-cultured with MT2 cells.Compared with control cells , the HeLa cells that were trans-fected with cGAS plasmid showed lower levels of Tax and p 19 proteins, suppressed expression of HTLV-1 Tax, p19, Env, HBZ and px at mRNA level , enhanced phosphorylation of IRF 3 and p65, and higher levels of IFN-β, IP-10, RANTES and TNF-αafter co-cultured with MT2 cells.Conclusion cGAS might promote the innate immune response and inhibit HTLV-1 replication in HTLV-1-infected HeLa cells .

Objective:To investigate the clinical and cardiac magnetic resonance (CMR) characteristics of heart involvement in patients with Fabry disease (AFD).Methods:From January 2018 to March 2021, eight AFD patients [3 males and 5 females, mean age (50±11) years old, range 26-60 years old] confirmed by genetic testing or pathology in Fuwai Hospital were retrospectively included in this study. At the same time, sixteen patients with hypertrophic cardiomyopathy (HCM) [6 males and 10 females, mean age (46±15) years old] and 16 healthy individuals [6 males and 10 females, mean age (51±11) years old] were included as controls. The clinical baseline data and CMR data of the patients were collected and analyzed. The CMR data were analyzed using the software CVI42, with the corresponding parameters automatically generated. One-way ANOVA or Kruskal-Wallis test was used to compare the differences in the parameters among the three groups. Independent-samples t test, Fisher precise test or Mann-Whitney U test were used for the comparison between each two groups. Results:Statistically significant difference was found in renal insufficiency between the HCM group and the AFD group; No other significant difference was found in other clinical factors and ECG results (all P>0.05). CMR results showed that in the AFD group, there were 5 cases with symmetric or roughly symmetric hypertrophy, and 3 with asymmetric hypertrophy. The late gadolinium enhancement (LGE) showed myocardial enhancement in 5 patients, mainly presenting as multiple intermural enhancement, and partially as local subendocardial enhancement. In the HCM group, fourteen cases suffered mainly asymmetric ventricular septal thickening, with or without thickening of other parts of left ventricular wall; and 2 cases had thickening of middle and distal part of the left ventricle. The LGE showed myocardial enhancement in 14 patients, which manifested as focal or patchy enhancement in hypertrophic myocardium, including focal enhancement in the right ventricular insertion of ventricular septum (more common) and subendocardial enhancement in the middle and far segments of left ventricle. Statistically significant difference was found in the differences between the left atrial anterior posterior diameter, the maximum wall thickness of left ventricular, the left ventricular myocardial mass index (LVMI) and the native T 1 value among the three groups (all P<0.001). However, there was no statistically significant difference in the left atrial anterior posterior diameter and the maximum wall thickness of left ventricular between AFD group and HCM group ( P>0.05). The LVMI in AFD group was higher than that in healthy group and HCM group (all P<0.05). Significant difference was found in the native T 1 value among the three groups, with the native T 1 value of the AFD group [(1 177.4±46.0) ms] was significantly lower than that of the healthy group [(1 244.5±34.3) ms] and the HCM group [(1 278.8±41.6) ms], with ( F=13.10, P<0.001). Conclusions:The clinical characteristics of AFD and HCM are quite similar. When AFD is suspected, CMR imaging should be the first choice for imaging examination. Especially, T 1 mapping imaging can provide important information for the diagnosis of AFD.

Objective To identify early Klebsiella pneumoniae (KP) infection after liver transplantation and its impact on prognosis. Methods Clinical data of 171 liver transplant recipients were retrospectively analyzed, and they were divided into the non-infection (n=52) and infection groups (n=119) according to the bacterial culture results at postoperative 2 weeks. In the infection group, KP was not detected in 86 cases (non-KP infection group), and KP was cultured in 33 cases (KP infection group). Preoperative, intraoperative and postoperative data were statistically compared between the non-infection and infection groups, and between the non-KP infection and KP infection groups. The risk factors of early KP infection after liver transplantation and the influencing factors of long-term survival of the recipients were analyzed. Results Compared with the non-infection group, model for end-stage liver disease (MELD) score and total bilirubin level were higher, the operation time was longer, the length of postoperative intensive care unit (ICU) stay and the length of hospital stay were longer, the amount of intraoperative red blood cell transfusion was higher, the hospitalization expense was higher, the incidence of severe complications was higher, white blood cell count, absolute neutrophil cell count and neutrophil-to-lymphocyte ratio at postoperative 14 and 30 d were higher, absolute lymphocyte count at postoperative 14 d was lower and hemoglobin level at postoperative 30 d was lower in the infection group. The differences were statistically significant (all P<0.05). Compared with the non-KP infection group, MELD score, total bilirubin level and aspartate aminotransferase (AST) level were higher, the operation time and the length of postoperative ICU stay were longer, the hospitalization expense was higher, the 90-d fatality was higher, the albumin level at postoperative 14 d was lower, and total bilirubin level at postoperative 30 d was higher in the KP infection group. The differences were statistically significant (all P<0.05). Among 33 recipients with KP infection, 16 cases were resistant to carbapenem antibiotics, and 7 of them died within postoperative 90 d. Seventeen cases were intermediate or sensitive to carbapenem antibiotics, and 4 of them died within postoperative 90 d. Preoperative MELD score ≥17 and operation time≥415 min were the independent risk factors for KP infection after liver transplantation (both P<0.05). The length of postoperative ICU stay ≥44 h and KP infection were the independent risk factors for long-term prognosis of liver transplantation (both P<0.05). Conclusions KP infection is an independent risk factor for death after liver transplantation. High preoperative MELD score and long operation time are the independent risk factors for early KP infection after liver transplantation.
