ABSTRACT
objectiveTo explore the specific molecular mechanism of neuronal apoptosis induced by ATM inactivation. MethodsCGNs matured 7 days in vitro were cultured 8 h with 25 K， 5 K or 25 K medium containing ATM-specific inhibitors （Ku55933， 10 µmol/L； Ku60019， 15 µmol/L） for Hoechst stain and apoptosis analysis， or cultured for different lengths of time （2， 4， 8 h） to detect the protein expression levels of ATM， caspase-3 and cleaved caspase-3 by Western blotting. ATM and GADD45α specific siRNA was transfected into C6 cells and CGNs， and its interference efficiency was verified by q-PCR and Western blotting. CGNs matured for 5 days in vitro were transfected with ATM specific siRNA and pCMV-EGFP by calcium phosphate for 48 h， Hoechst staining and apoptosis analysis were performed. CGNs matured for 7 days in vitro were treated with 25 K medium containing ATM specific inhibitors for 8 h， transcriptome sequencing， differential expression gene identification and pathway enrichment analysis were performed. CGNs matured for 5 days in vitro were co-transfected with GADD45α specific siRNA and pCMV-EGFP by calcium phosphate for 48 h， then treated with 5 K or 25 K medium containing 15 µmol/L Ku6 for 8 h. Hoechst staining and apoptosis analysis were performed. ResultsCompared with the 25 K， CGNs nuclear pyknosis rate， cleaved Caspase-3 and ATM protein expression level were increased in the 5 K and ATM-specific inhibitor groups. The mRNA and protein expression levels of ATM and GADD45α were effectively reduced after transfection of ATM and GADD45α specific siRNA in C6 cells and CGNs. Compared with control， CGNs transfected with ATM specific siRNA showed a higher nuclear pyknosis rate. Totally 835 genes were identified to be up-regulated and 848 genes to be down-regulated in the Ku55933 treatment group； 454 genes were identified to be up-regulated and 314 genes to be down-regulated in the Ku6 treatment group； 274 genes were co-up regulated in the Ku5 and Ku60019 treatment groups， while 179 genes were co-down-regulated in the Ku5 and Ku6 treatment groups and the expression of ATM downstream target GADD45α was upregulated. The enrichment results showed that TNF signaling pathway， NF-κB signaling pathway and Apoptosis signaling pathway were significantly enriched. Compared with control， mRNA and protein expression levels of GADD45α were increased in inhibitor treatment and 5 K， while knocking down GADD45α resulted in a decrease in nuclear pyknosis rate in the Ku60019 and 5 K treatment group. ConclusionLoss of ATM activity induces GADD45α-dependent cerebellar granular neuronal apoptosis.
ABSTRACT
@#Objective To provide experience for clinical diagnosis and treatment through exploring the perioperative characteristics and short-term treatment outcomes of adult cardiac surgery in patients with prior coronavirus disease-2019 (COVID-19). Methods A retrospective analysis was performed on patients undergoing coronary artery bypass grafting (CABG) or valve surgery in the Department of Cardiac Surgery of Beijing Anzhen Hospital from December 26, 2022 to December 31, 2022, and previously diagnosed with COVID-19 before surgery. Results Finally 108 patients were collected, including 81 males and 27 females, with an average age of 60.73±8.66 years. Two (1.9%) patients received emergency surgery, and the others received elective surgery. The 86.1% of patients had been vaccinated, and the duration of COVID-19 was 5.0 (4.0, 7.0) days. The time from COVID-19 to operation was 15.0 (12.0, 17.8) days. Eighty-nine patients received CABG, of which off-pump CABG was dominant (92.1%). Nineteen patients received valve surgery. The rate of delayed extubation of ventilator was 17.6%. The ICU stay was 21.0 (17.3, 24.0) hours, and the postoperative hospital stay was 7.0 (6.0, 8.0) days. Three (2.8%) patients were treated with intra-aortic balloon pump (IABP), one (0.9%) patient was treated with extracorporeal membrane oxygenation (ECMO), one (0.9%) patient was treated with continuous renal replacement therapy (CRRT) due to acute renal insufficiency, three (2.8%) patients were treated with temporary pacemaker, and one (0.9%) patient underwent rethoracotomy. In terms of postoperative complications, the incidence of cerebrovascular accident, acute renal insufficiency, gastrointestinal bleeding and septicemia was 0.9%, respectively, and the incidence of acute heart failure, lung infection, and liver insufficiency was 1.9%, respectively. All patients recovered and were discharged from hospital, and no in-hospital death occurred. Conclusion The utilization rate of postoperative IABP, ECMO, CRRT, temporary pacemaker and the incidence of serious complications in patients with prior COVID-19 are not higher than those of normal patients, and the short-term treatment outcome is good.
ABSTRACT
Objective:This study was performed to assess the effect of glycemic control on atrial fibrillation recurrence rates after heart surgery concomitant with Cox-Maze Ⅳ ablation.Methods:A retrospective analysis was performed on 317 diabetic patients with atrial fibrillation who underwent cardiac surgery combined with Cox-Maze Ⅳ ablation in our hospital from May 2016 to February 2020. The patients were followed up for(37.7±27.7) months, and the data of atrial fibrillation recurrence and clinical outcome were collected and compared. The limited cubic spline model was used to analyze the dose-relationship between HbA1c level and the recurrence of atrial fibrillation. The univariate and multivariate Cox proportional regression analysis was used to explore the risk factors of recurrent atrial fibrillation after Cox-Maze Ⅳ ablation. Results:Higher glycated hemoglobin(HbA1c) at the time of ablation was associated with higher post-ablation recurrence rates. The cumulative survival freedom from atrial fibrillation recurrence for patients with HbA1c ≥7.4% at time of operation at 12, 24, 36 and 48 months were 96.3%、75.8%、52.7% and 35.7%, respectively( P<0.001). Besides, the rates of all-cause mortality, cardiac mortality and rehospitalization were significantly lower in patients with HbA1c<7.4%(1.7% vs. 6.3%, P=0.03; 1.1% vs. 5.6%, P=0.02 and 5.7% vs. 20.4%, P=0.01). The multivariate Cox regression model showed that HbA1c was an independent risk factor for atrial fibrillation recurrence( P<0.05). Conclusion:Higher preoperative HbA1c levels were associated with increased recurrence of atrial fibrillation and adverse clinical outcomes in patients undergoing cardiac surgery combined with Cox-Maze Ⅳ ablation.
ABSTRACT
The treatment of heart failure is a common clinical problem faced by the medical community all over the world. It is also the only cardiovascular disease in the world that is on the rise. Although drug therapy for heart failure has made great progress in recent years, there are still many problems. Therefore, reversing ventricular remodeling, assisting or even replacing the function of the damaged heart and improving the prognosis and quality of life of patients with heart failure through surgical treatment will become the main battlefield for the future treatment of heart failure. As a transitional support therapy or permanent replacement therapy before heart transplantation, ventricular assist device can significantly improve the survival and quality of life of patients with heart failure, and is becoming an important treatment method for patients with end-stage heart failure. This paper aim to review the history and prospect of ventricular assist devices after heart failure.
ABSTRACT
Objective:To summarize the experience of reoperation for 23 cases of cardiac myxoma recurrence.Methods:From January 2002 to December 2018, 1106 patients with cardiac myxoma underwent surgical treatment. Among them, 23 patients underwent reoperation after recurrence. 10 males and 13 females with an average age of (50.5±10.8) years old. There were 22 patients with secondary operation and 1 patient with four operations. 3 cases with mitral insufficiency and 1 case with tricuspid insufficiency. There were 20 patients with NYHA Ⅰ-Ⅱ and 3 patients with Ⅲ-Ⅳ. A total of 1 083 patients with cardiac myxoma undergoing primary operation were selected as the control group. The operation time, cardiopulmonary bypass time, aortic clamping time, ICU monitoring time, ventilator assisted breathing time, postoperative hospital stay, in-hospital mortality and cardiac ejection fraction at discharge were compared between the two groups.Results:8 cases (34.8%) had the first onset in the left atrial septum, and 15 cases (65.2%) in other parts. Recurrence site: left atrium in 17 cases(73.9%), left ventricle in 2 cases (8.7%), right atrium in 3 cases (13.0%), right ventricle in 1 case (4.3%). Reoperation accounted for 2.1% of cardiac myxoma surgery in the same period. The median recurrence time of 13 patients was 24 months. During the same period, mitral valve replacement was performed in 2 cases, mitral valvuloplasty in 1 case and tricuspid valve plasty in 1 case. The average operation time was (3.9±2.8) h, cardiopulmonary bypass time was (107.6±33.8) min, aortic clamping time was (64.9±23.8) min, ICU monitoring time was (20.1±16.0) h, ventilator assisted breathing time was (16.9±8.5) h, cardiac ejection fraction at discharge was 0.51±0.10, postoperative hospital stay was (8.3±1.5) days. The median follow-up time was 5 (1-18) years. One case (4.3%) died of all causes. There was no significant difference in ICU monitoring time, ventilator assisted breathing time, discharge cardiac ejection fraction, postoperative hospital stay and hospital mortality between reoperation patients and one operation ( P>0.05). Conclusion:Atypical cardiac myxoma has a high recurrence tendency after operation. Regular follow-up after the first operation of cardiac myxoma is a necessary means to early detect recurrence and avoid complications. Reoperation after recurrence can still achieve satisfactory results.
ABSTRACT
Objective: To investigate the related factors of myocardial fibrosis in patients with hypertrophic cardiomyopathy. Methods: Patients with hypertrophic cardiomyopathy, hospitalized in the First People's Hospital of Yunnan Province from January 2016 to May 2020, were included in this cross-sectional study. Patients were divided into delayed enhancement positive group (fibrosis group) and non-delayed enhancement group (non-fibrosis group). According to the maximum left ventricular end diastolic wall thickness (LVMWT), patients in the fibrosis group was further divided into mild hypertrophy group, moderate hypertrophy group and severe hypertrophy group. The baseline clinical data of patients were collected by medical record management system. All enrolled patients underwent cardiac magnetic resonance imaging (CMR). The presence and location of myocardial fibrosis were identified by CMR gadolinium contrast delayed enhancement (LGE). The range of LGE (LGE%) was calculated by visual analysis. The levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI) in peripheral blood were measured . Results: A total of 48 patients ( age (46.4±14.3) years, 42 (87.5%) males) were enrolled. There were 34 LGE positive cases (fibrosis group) and 14 LGE negative cases (non-fibrosis group). Compared with non-fibrosis group, patients in fibrosis group were younger (P=0.038) and prevalence of NYHA grade Ⅲ/Ⅳ was higher (P=0.00). Compared with non-fibrosis group, patients in fibrosis group had thicker LVMWT (P= 0.008), higher left ventricular mass index(LVMI) (P=0.001), higher left ventricular end diastolic volume (LVEDV) (P=0.043), lower left ventricular ejection fraction (LVEF) and cardiac index (CI) (all P <0.05). The levels of NT-proBNP and cTnI were significantly higher in fibrosis group than in non-fibrosis group (2 760.5 (1 503.4, 3 783.6) ng / L vs. 861.3 (552.2, 1 092.8) ng / L, P=0.002; 0.970 (0.448, 1.684)μg / L vs. 0.147 (0.033, 0.251)μg / L, P=0.041).In fibrosis group, there were 15 cases of mild hypertrophy (mild hypertrophy group), 10 cases of moderate hypertrophy (moderate hypertrophy group), and 9 cases of severe hypertrophy (severe hypertrophy group). The LGE% and NT-proBNP and cTnI increased in proportion with increasing myocardial hypertrophy (P<0.05). LGE% was negatively correlated with age (r=-0.618, P=0.011), and positively correlated with NT-proBNP and cTnI levels (r=0.271, P=0.010; r=0.111,P=0.013, respectively), and positively correlated with LVEDV, LVMWT and LVMI (r=0.438, P=0.09; r=0.735, P=0.001; r=0.532, P=0.034, respectively). Conclusions: In patients with hypertrophic cardiomyopathy, the extent of myocardial fibrosis increases with the increase of myocardial hypertrophy. Myocardial fibrosis is negatively correlated with age, and positively correlated with NT-proBNP and cTnI, as well as LVEDV, LVMWT and LVMI in this patient cohort.

ABSTRACT
Objective:To investigate the difference between the short-term and long-term survival rates of patients undergoing tricuspid valve replacement with biological and mechanical valves.Methods:273 patients who received tricuspid valve replacement were selected from our Hospital from November 1993 to August 2018. The mean follow-up time was(8.2±5.6) years. The total follow-up rate was 95%. Kaplan-Meier method was used to make survival curves of the two groups and log rank test was used to compare the differences between the two groups. In addition, this study made the comparison of preoperative, intraoperative and postoperative information and long-term survival rate between these two groups.Results:There was no significant difference in demographic characteristics and baseline between mechanical valve group and biological valve group. 16 patients died in the mechanical valve group and 22 in the biological valve group. In the mechanical valve group, 14 cases died of postoperative low cardiac output syndrome and 2 cases died of gastrointestinal hemorrhage. 22 patients were died of low cardiac output syndrome. The auxiliary time in the mechanical valve group was longer than that in the biological valve group[(151.76±70.30)min vs.(131.62±60.25)min, P=0.013)]. There was no significant difference in long-term survival rate between the two groups in Kaplan- Meier survival curve( P=0.234). Conclusion:There is no difference in short-term and long-term survival rate between mechanical valve and biological valve in tricuspid valve replacement.

This article reviews the impact of fecal microbiota transplantation in digestive system disorders, neuropsychiatric disorders, endocrine system disorders, cardiovascular and cerebrovascular system disorders, blood system disorders and other typical bacterial intervention methods in recent years.
ABSTRACT
Objective:To investigate short-term and long-term outcomes of off-pump coronary artery bypass grafting(OPCABG)in patients aged 80 years and over.Methods:In this retrospective study, clinical data were collected, from June 2005 to July 2014, of 31 patients aged 80 and over years with left ventricular dysfunction who had received OPCABG in Beijing Anzhen Hospital and a follow-up of 3-12 years after discharge.Results:Ages of the patients ranged from 80 to 88 years with a mean age of(82.0±2.1)years.There were 25 males(80.6%). The mean left ventricular ejection fraction(LVEF)of patients was(42.0±6.5)% before operation, and 15 patients had LVEF less than 35%(48.4%). The average operation time was 4 hours.Three patients died in hospital(9.7%), of whom, one died from acute respiratory failure and the two others from low cardiac output syndrome.Perioperative complications included myocardial infarction(1 case, 3.2%), acute cerebral infarction(2 cases, 6.5%), tracheal intubation(3 cases, 9.7%), secondary thoracotomy and hemostasis(1 case, 3.2%), continuous renal replacement therapy(3 cases, 9.7%)and perioperative intra-aortic balloon pump(IABP)(8 cases, 25.8%). Twenty-eight patients were followed up for 3-12 years(median, 8.0 years), and no one had withdrawn.There were 10 all-cause deaths(35.7%), including 5 cardiogenic deaths(17.9%), 2 lung cancer deaths(7.1%), 2 deaths due to sepsis from systemic infection(7.1%), and 1 death from unknown causes.Besides, 2 patients had re-admission(7.1%), 2 patients suffered angina(7.1%)and 1 patient(3.6%)had recurrent myocardial infarction(3.6%). No patient received re-revascularization.Coronary computed tomography angiography(CTA)was performed on all surviving patients 1 year after surgery, and the patency rate of vascular bridges was 100%.Conclusions:Both short-term and long-term clinical outcomes of OPCABG are fair in patients aged over 80 years with left ventricular dysfunction, but the mortality and risk of complications are still high, and comprehensive preoperative evaluation is needed for these patients.

ABSTRACT
Spatholobi Caulis, the vine stem of Spatholobus suberectus and widely used in China and Southeast Asian nations, has the effects on nourishing the blood and promoting blood flow, regulating menstruation and relieving pain, and invigorating the nerves. Through consulting the herbal textual and local chronicles, we summarized the original textual research and medicinal evolution on Spatholobi Caulis to analyze the changes of varieties in different historical periods. Further, the major active ingredient in Spatholobi Caulis was discussed. According to the literature to date, 60 flavonoids compounds have been isolated and could be divided into isoflavones, dihydroflavones, flavanols, dihydroflavonols, procyaninides, chalcones, pterocarpans, isoflavanols, isoflavanones and aurone according to their molecular structures. These indicative ingredients in Spatholobi Caulis showed pharmacological activities on regulation of the blood system, anti-tumor, anti-oxidation, anti-virus, anti-bacteria and inhibition of melanin deposition. This review will provide reference and basis for the sustainable use of resources and industry development on Spatholobi Caulis.
ABSTRACT
<p><b>BACKGROUND</b>Debate on treatment for young patients with coronary artery disease still exists. This study aimed to investigate the intermediate- and long-term outcomes between coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in patients aged 18-45 years with diabetes mellitus (DM).</p><p><b>METHODS</b>Between January 2006 and March 2016, a total of 2018 DM patients aged 18-45 years including 517 cases of CABG and 1501 cases of PCI were enrolled in the study. Using propensity score matching (PSM), 406 patients were matched from each group. The intermediate- and long-term data were collected. The primary end point of this study was long-term death. The secondary end points included long-term major adverse cardiovascular and cerebrovascular events (MACCEs), stroke, angina, myocardial infarction (MI), and repeat revascularization.</p><p><b>RESULTS</b>Before PSM, the in-hospital mortality was 1.2% in the CABG group and 0.1% in the PCI group, with statistically significant difference (P < 0.0001). The 10-year follow-up outcomes including long-term survival rate and freedom from MACCEs were better in the CABG group than those in the PCI group (97.3% vs. 94.5%, P = 0.0072; 93.2% vs. 86.3%, P < 0.0001), but CABG group was associated with lower freedom from stoke compared to PCI group (94.2% vs. 97.5%, P = 0.0059). After propensity score-matched analysis, these findings at 10-year follow-up were also confirmed. Freedom from MACCEs was higher in CABG group compared to PCI group, but no significant difference was observed (93.1% vs. 89.2%, P = 0.0720). The freedom from recurrent MI was significantly higher in CABG patients compared with PCI patients (95.6% vs. 92.5%, P = 0.0260). Furthermore, CABG was associated with a higher rate of long-term survival rate than PCI (97.5% vs. 94.6%, P = 0.0403). There was no significant difference in the freedom from stroke between CABG and PCI groups (95.3% vs. 97.3%, P = 0.9385). The hospital cost was greater for CABG (13,936 ± 4480 US dollars vs. 10,926 ± 7376 US dollars, P < 0.0001).</p><p><b>CONCLUSIONS</b>In DM patients aged 18-45 years, the cumulative survival rate, and freedom from MI and repeat revascularization for CABG were superior to those of PCI. However, a better trend to avoid stroke was observed with PCI.</p>
ABSTRACT
Objective: Based on nationwide cardiovascular surgery registry database, to analyze the current status and future development of minimally invasive cardiovascular surgery (MICS) in China. Methods: There were 45 institutions from 19 provinces nationwide involved in Chinese cardiovascular surgery technique registry study. A total of 16480 adult patients with cardiovascular surgery from 2010-09 to 2012-03 were divided into 2 groups, Conventional surgery group, n=14503 and MICS group, n=1977. The basic clinical conditions were analyzed and compared between 2 groups in order to explore the current status and future development of MICS in China. Results: Compared with Conventional surgery group, the patients in MICS group had the younger age, better and stable pre-operative condition. In MICS group, compared with 4 other common procedures, the patients who received hybrid procedure had obviously shorter cardiopulmonary bypass (CPB) time, aortic occlusion time, ventilator using time, ICU and in-hospital stay time, meanwhile decreased post-operative drainage volume;except for Robotic surgery, it required less red blood cells and plasma at during and post-operative time, all P Conclusion: MICS are widely used in China, its short-term safety and efifcacy are conifrmed. Upon cardiovascular disease spectrum changing, the MICS procedures will be adjusted accordingly.
ABSTRACT
Mild traumatic brain injury (mTBI) is a common type of brain disorders among young adults. The dysfunction of the brain is often exacerbated due to diffuse axonal injury (DAI) which based on the injury of white matter fibers and axons. Since mild and moderate brain injury or DAI are diffuse and subtle, conventional CT and MRI are difficult to make a positive diagnosis. Recent clinical study indicated that functional magnetic resonance imaging has a high detection rate in the diagnosis of acute mild and moderate brain injury, especially the diffusion tensor imaging (DTI) and 1H-magnetic resonance spectroscopy (1H-MRS). This paper has reviewed the principles and characteristics of DTI and 1H-MRS, and recent research in the clinical and animal experiments on brain injury.

<p><b>OBJECTIVE</b>To explore the causes of nonspecific chronic cough in children and relationship between transient receptor potential vanilloid 1 (TRPV1) gene polymorphisms and nonspecific chronic cough.</p><p><b>METHODS</b>A total of 195 children with chronic cough were followed up half a month, one month and three months after their first visit to hospital. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to examine polymorphisms of the TRPV1 gene in the children. A total of 205 healthy or surgical children without chronic cough served as the control group.</p><p><b>RESULTS</b>The etiologic distribution of the 195 children with chronic cough was as follows: 96 (49.2%) cases of cough variant asthma (CVA), 48 (24.6%) cases of CVA complicated by upper airway cough syndrome (UACS), 34 (17.4%) cases of post-infectious cough, and 17 (8.7%) cases of UACS. Three genotypes were identified in both groups at positions rs222747 (CC, GC and GG), rs222748 (CC, TC and TT) and rs8065080 (CC, TC and TT). The frequencies of genotype and allele at position rs222747 did not accord with the law of Hardy-Weinberg. There was no significant difference in frequencies of genotype and allele at positions rs222748 and rs8065080 between the two groups.</p><p><b>CONCLUSIONS</b>CVA, UACS and post-infectious cough are common causes of nonspecific chronic cough in children. TRPV1 gene polymorphisms at positions rs222748 and rs8065080 may be unrelated to nonspecific chronic cough in children.</p>

Twenty-five patients were male and 29 were female with the average age of 52.8 years. Fifty-one of which were iliofemoral and popliteal, the other 3 were iliofemoral. The course were ≤ 7 d in 45 cases and these were 8 to 30 d in 9 cases. Urokinase of 300 000 U was infused through catheters per 2 h twice a day. Meanwhile 4000 U of low weight heparin was administered subcutaneously per 12 h, or heparin infusion at dosage of 18 U×kg(-1)×h(-1).</p><p><b>RESULTS</b>The procedure technically succeeded in all patients. In total cases venous score decreased to 4.6 ± 2.1 post 6 to 10 d of thrombolysis from 10.8 ± 1.0 with thrombolysis rate of 58% ± 18% which was not significantly different between groups of ≤ 7 d and 8 to 30 d (t = 1.02, P = 0.34). On 14(th) day, 11 patients (20.4%) completely recovered, 35 cases (64.8%) experienced large improvement, 8 patients (14.8%) had mild improvement and nobody was failed, resulting in total efficacy of 100%. No patient developed clinical symptomatic pulmonary embolism. SpO2 did not alter markedly post thrombolysis [(91.0 ± 2.6)% vs. (90.8 ± 2.4)%, t = 2.03, P = 0.05]. No patients suffered from cerebral hemorrhage and haemoturia, and catheter induced inflammation occurred in 4 cases (7.41%). There was mild bleeding in puncture sites in 11 patients (20.4%) during the course. There were 36 patients (66.7%) had been followed up with the time of 6 to 21 months. In which 31 cases had no lower extremity edema or had mild edema after activities. Two patients developed serious edema after activities for deep venous insufficiency. Three cases combined with malignant tumor or renal failure recurred.</p><p><b>CONCLUSIONS</b>For early left extremity DVT which is entire without free floating clots and no thrombosis in vena cava, catheter directed thrombolysis without filter protection maybe administered with safety, efficiency and lower expense.</p>

<p><b>OBJECTIVE</b>To investigate and search correlative proteins of keloid by comparing the results of differential proteomic analysis between keloid and normal skin.</p><p><b>METHODS</b>From January 2010 to June 2010 two-dimensional gel electrophoresis was used to define patterns of protein expression in keloid skin from 8 patients and matched normal skin from 3 patients. Differential expression protein spots were showed and analyzed by matrix-assisted laser desorption ionization-time of flying/time of flying (MALDI-TOF/TOF) mass spectrometry.</p><p><b>RESULTS</b>This study succeeded to provide a two-dimensional protein profiling comparison between normal skin and keloid. Gel-analysis software identified an average of 2978 spots in keloid while 3053 spots in normal skin and statistical filtering yielded 40 spots of a 4-fold change, 32 of which were identified by using mass spectrometry, 20 were up-regulated and 12 were down-regulated. Functional analysis revealed that these proteins could be fractionated to carrier proteins (3 proteins), signal transduction proteins (4 proteins), proliferation and apoptosis related proteins (2 proteins), cytoskeleton proteins (6 proteins), extracellular matrix proteins (8 proteins), immunity related proteins (3 proteins), tumor related proteins (2 proteins), and function unknown protein (4 proteins).</p><p><b>CONCLUSIONS</b>Proteomic analysis can identify the proteins with variance of keloid versus normal skin. The further research to these differential proteins may help reveal the pathogenesis of keloid and provide new treatments for keloid.</p>
