ABSTRACT

Objective:To compare the awakening effects of enriched environmental quantitative stimulation and conventional rehabilitation on patients with consciousness disorder after traumatic brain injury (TBI).Methods:A retrospective cohort study was conducted to analyze the clinical data of 60 patients with consciousness disorder after TBI admitted to Hospital of Zhejiang Provincial Armed Police Corps from October 2021 to October 2022, including 38 males and 22 females, aged 26-72 years [(41.6±13.2)years]. The injury was located at the frontal and temporal lobe in 37 patients, at the brain stem in 9, and at the thalamus in 14. The types of injury included cerebral contusion and laceration in 36 patients and intracerebral hematomas in 24 patients. The Glasgow Coma Scale (GCS) score on admission was 5-8 points in 11 patients, 9-12 in 34, and 13-15 in 15. Disease course was (19.2±5.4)days. A total of 30 patients received conventional rehabilitation treatment (conventional rehabilitation group) and 30 patients received enriched environmental quantitative stimulation on the basis of conventional rehabilitation treatment, which lasted 4 cycles in 28 days (quantitative stimulation group). The Coma Recovery Scale-Revised (CRS-R) score, Activities of Daily Living (ADL) score, and brainwave α/δ ratio (ADR) before treatment and at the second and fourth treatment cycles were compared between the two groups. The incidence of complications at the end of the fourth treatment cycle and the rate of favorable outcome of Glasgow Outcome Scale (GOS) at the last follow-up were compared between the two groups.Results:All the patients were followed up for 6-12 months [(8.3±2.5)months]. There were no significant differences in CRS-R score, ADL score, or brainwave ADR between the two groups before treatment ( P>0.05). At the second treatment cycle, they were (13.03±0.73)points, (14.83±0.95)points and 0.35±0.11 respectively in the quantitative stimulation group, which were all higher than those in the conventional rehabilitation group [(11.18±0.14)points, (8.74±0.43)points and 0.29±0.09 respectively] ( P<0.05). At the fourth treatment cycle, they were (17.83±0.23)points, (52.93±10.75)points and 0.44±0.11 respectively in the quantitative stimulation group, which were all higher than those in the conventional rehabilitation group [(13.67±0.35)points, (40.56±7.15)points and 0.37±0.07 respectively] ( P<0.05). The CRS-R score, ADL score, and brainwave ADR at the second treatment cycle were significantly higher than those before treatment, and they were even higher at the fourth treatment cycle than those at the second treatment cycle ( P<0.05). At the end of the fourth treatment cycle, the incidence of complications in the quantitative stimulation group was 13.3% (4/30), which was lower than that of the conventional rehabilitation group [36.7% (11/30)] ( P<0.05). At the last follow-up, the favorable outcome rate of GOS was 80.0% (24/30) in the quantitative stimulation group, which was superior to 66.7% (20/30) in the conventional rehabilitation group ( P<0.05). Conclusion:Compared with the conventional rehabilitation treatment, enriched environmental quantitative stimulation for patients with consciousness disorder after TBI achieves enhanced consciousness level, activity of daily life and electroencephal reactivity, together with decreased incidence of complications and improved prognosis.

ABSTRACT

Objective:To investigate the value of flattening filter-free (FFF) mode in postoperative deep inspiration breath-hold (DIBH) intensigy-modulated radiotherapy for left breast cancer.Methods:A retrospective case series study was conducted. Clinical data of 21 patients with left breast cancer who underwent DIBH intensity-modulated radiotherapy after modified radical surgery in Meizhou People's Hospital from January 2021 to December 2022 were retrospectively analyzed. On the DIBH-mode CT of each patient, the 7-field intensity-modulation plan was designed using the plan developed in the 6 MV FFF-mode (FFF group) or the plan developed in the 6 MV flattening filter (FF)-mode (FF group). The target areas and organs at risk, dosimetric and biological parameters, and dose validation results were compared between the two plans.Results:Twenty-one patients were female with the age [ M ( Q1, Q3)] of 47 years old (32 years old, 61 years old). The percentage of target areas receiving 95% of the prescribed dose (V 95%) was (95.9±0.8)% and (95.7±1.9)% in the FF and FFF groups ( t = 2.98, P = 0.089), and the maximum dose was (5 401±251) cGy and (5 424±201) cGy ( t = 2.85, P = 0.181), the fitness indices were 0.88±0.05 and 0.87±0.06 ( t = 0.32, P = 0.562), the homogeneity indices were 1.06±0.01 and 1.07±0.02 ( t = 2.91, P = 0.009), the equivalent uniform doses (EUD) were (51.81±0.21) Gy and (51.97±0.20) Gy ( t = 0.51, P = 0.309), and the tumor control probability (TCP) was (99.68±0.01)% and (99.61±0.02)% ( t = 0.81, P = 0.560). The plans of the FFF group and the FF group were compliant, and the doses of all organs at risk to be irradiated were within the clinically acceptable range, and the radiation doses in the FFF group in the left lung [5 Gy irradiated volume (V 5 Gy), mean dose (D mean), EUD and normal tissue complication rate (NTCP)], right lung (V 5 Gy and D mean), heart (V 10 Gy, D mean, EUD and NTCP), and right breast (V 5 Gy, D mean and EUD) were differently lower than those in the FF group, and the differences were statistically significant (all P < 0.05). The monitor units in the FFF and FF groups were (984±132) MU and (751±145) MU ( t = -1.25, P < 0.001), and the total beam-on time was (1.4±0.3) min and (2.2±0.4) min ( t = 0.68, P < 0.001); individual field beam-on time was (12±7) s and (16±10) s ( t = 2.68, P = 0.001), and the beam-on time for each field in patients of the FFF group was less than 25 s; γ pass rates were (97.1±2.8)% and (97.6±2.1)% ( t = 0.59, P = 0.484). Conclusions:In the intensity-modulated radiotherapy of left breast cancer, the radiation dose of the energy to the critical organs in FFF mode is lower and has higher dose rate and shorter treatment time. FFF combined with DIBH technique has positive clinical significance in the intensity-modulated radiotherapy of breast cancer.

ABSTRACT

Objective:To analyze the epidemiological characteristics and spatiotemporal characteristics of human brucellosis in Henan Province.Methods:Data of human brucellosis in Henan Province from 2005 to 2021 were collected through the China Disease Prevention and Control Information System, and a descriptive epidemiological method was used to analyze the epidemic profile of brucellosis in Henan Province and the three distribution characteristics. Global and local spatial autocorrelation were used to analyze the spatial distribution and the hot spots of brucellosis in Henan Province, respectively, and spatiotemporal scanning was used to analyze the spatiotemporal clustering regions of brucellosis in Henan Province.Results:A total of 39 862 brucellosis cases were reported in Henan Province from 2005 to 2021, with an average annual incidence of 2.44/100 000, and the number of cases showed an overall increasing trend each year (χ 2trend = 11 127.85, P = 0.001). The onset months were mainly concentrated from March to July, accounting for 59.00% (23 517/39 862), with May as the peak (5 478 cases). Cases of brucellosis were reported in 157 counties (cities, districts) of the province. The ratio of male to female was 2.52∶1.00 (28 542/11 320). Farmers were the main occupation, with 32 985 cases (82.75%). The age of onset was mainly 45 to 65 years old, with 20 226 cases (50.74%). The global spatial autocorrelation analysis showed that the global Moran's I was > 0, Z > 1.96, and P < 0.05 in all years except 2006 - 2008, showing spatial clustering. Further local spatial autocorrelation analysis was performed, and high-high and low-low clustering areas existed in 2012 - 2021 ( P < 0.01). Spatiotemporal scanning analysis showed that there was one spatiotemporal cluster in the high incidence area and two spatiotemporal clusters in the low incidence area. The high incidence cluster was centered in Neixiang County, covering 48 counties (cities, districts) including Song County and Ruzhou City, and the aggregation time was from 2014 to 2021. The two low incidence clusters were centered in Yongcheng City and Boai County, covering 58 and 18 counties (cities, districts), respectively, and the aggregation time was 2016 - 2021 and 2005 - 2012, respectively. Conclusion:The overall incidence of brucellosis in Henan Province is on the rise from 2005 to 2021, with middle-aged and elderly male farmers as the main affected population, and there are spatiotemporal clusters of brucellosis in Henan Province.

ABSTRACT

Brain edema could be secondary to cerebral lesion caused by a variety of reasons, severe cases may result in brain herniation or even death. Accurate real-time monitoring of cerebral edema, rational application of dehydrating drugs, and timely treatment of cerebral edema were very important for patients. However, there were defects in the monitoring methods commonly used in clinical practice. Noninvasive brain-edema monitoring was a new method, which can quantify the degree of brain edema by electromagnetic disturbance and directly reflect the state of brain edema. This article reviews the application of noninvasive brain-edema monitoring in the treatment of in critically ill patients with traumatic brain injury.

ABSTRACT

Objective:To report the first case of sever fever with thrombocytopenia syndrome caused by severe fever with thrombocytopenia syndrome virus (SFTSV) in Puyang city, and to study the epidemiological and molecular characteristics of S, M, L fragments of the SFTSV isolate.Methods:The epidemiological characteristics of this case was analyzed with epidemiological methods. SFTSV was isolated from the patient′s serum sample. Nucleic acid of SFTSV was extracted and detected by fluorescent RT-PCR. A multiplex PCR method was constructed to amplify the nucleic acid sequence of the virus. whole-genome sequencing was performed on the next-generation sequencing platform. MEGA11 and DNAStar was used for homology analysis and a phylogenetic tree was constructed.Results:Epidemiological investigation showed that the patient and his close contacts had no history of travel or tick bite within 14 d, but had a history of fieldwork. The patient′s serum sample was positive for SFTSV nucleic acid. Genetic analysis showed that the S, M, L gene fragments of the first SFTSV isolate in Puyang belonged to genotype E. This isolate shared 94.8%-99.6%, 94.0%-99.8% and 95.7%-99.7% nucleotide sequence homology with the representative strains acquired from GeneBank in S, M, L gene fragments, respectively.Conclusions:This case was the first case of SFTSV-caused severe fever with thrombocytopenia syndrome in Puyang. The SFTSV isolate shared a close homology with domestic isolates, but its genotype was significantly different from the SFTSV strains isolated in Henan in recent years, indicating that it might an imported case from other places in Henan Province or Hubei Province. Disease monitoring and professional training for medical personnel should be strengthened and more attention should be paid to the evolution and mutation of SFTSV.

ABSTRACT

Objective:To investigate the effect of SCN1A gene polymorphism (SCN1A-rs3812718) on the alterations of spontaneous brain activity using amplitude of low-frequency fluctuations (ALFF) of MR in patients with temporal lobe epilepsy (TLE).Methods:A total of 37 TLE patients (TLE group) admitted to the Epilepsy Center of the 900th Hospital of Joint Logistic Team from March 2018 to August 2019 were retrospectively analyzed, and another 28 healthy volunteers matched for gender, age, and years of education with the TLE group were selected as the healthy control group (HC group). Sixty-five subjects were divided into four groups by genotype and diagnosis: 34 cases in AA/AG-TLE subgroup, 3 cases in GG-TLE subgroup, 20 cases in AA/AG-HC subgroup and 8 cases in GG-HC subgroup. All subjects underwent sagittal 3D-T 1WI and resting-state functional MRI using a Siemens 3.0 T Trio Tim MR scanner. Then ALFF values of the four groups were calculated using DPABI by the MATLAB 2010 platform. The ALFF values between two groups were compared by independent samples t-test. The ALFF values of different genotypes at rs3812718 locus in TLE and HC group were analyzed by multivariate analysis of variance to find out the corresponding brain regions with interaction, and then post hoc simple effect analysis was performed. Results:The ALFF values in TLE group significantly increased in left marginal lobe, left parahippocampal gyrus, left fusiform gyrus, left hippocampus, right insular lobe and right inferior temporal gyrus (Alphasim corrected P<0.001) and decreased in the left superior frontal gyrus, left middle frontal gyrus, left inferior frontal gyrus, right middle frontal gyrus, right precuneus, left precuneus, bilateral cingulate gyrus and right angular gyrus (Alphasim correction P<0.05) compared with HC group. Subjects carrying the non-risk G allele had higher ALFF values in the right inferior temporal gyrus, right fusiform gyrus, and right cerebellum than subjects carrying the risk A allele ( t=3.30, Alphasim corrected P=0.002). There was a significant interaction effect on posterior cerebellar lobe, left anterior cerebellar lobe, left inferior temporal gyrus, left superior parietal lobule and right precuneus of TLE patients with SCN1A-rs3812718 genotype. Post-hoc simple effect analysis showed that ALFF significantly increased in the left posterior cerebellar lobe, left anterior cerebellar lobe, left inferior temporal gyrus and left fusiform gyrus in GG-TLE subgroup ( t=5.97, P<0.001), but significantly decreased in the right superior parietal lobule, right precuneus, right posterior cerebellar lobe in AA/AG-TLE subgroup compared to the HC group. Compared with GG-TLE subgroup, ALFF in left posterior cerebellar lobe, left fusiform gyrus and left inferior temporal gyrus decreased in AA/AG-TLE subgroup. Conclusion:SCN1A gene polymorphism in the rs3812718 locus affects spontaneous neural activity in resting state, which may be one of the pathophysiological mechanisms of TLE.

ABSTRACT

OBJECTIVE To study the triterpenoid saponins from Anemone rivularis var. flore-minore and their antitumor activities. METHODS The n-butanol extract of 70% ethanol extract from rhizome of the plant was separated. The triterpenoid saponins were separated and purified by normal silica gel column chromatography ,reversed phase ODS column chromatography , Sephadex LH- 20 gel column chromatography and semi-preparation high performance liquid chromatography. The structures of these saponins were identified by spectral analysis (NMR and MS )and physical and chemical properties. MTT assay was used to test the proliferation inhibitory activity of the compounds against five kinds of human tumor cells (HL-60 cells,A549 cells,HepG2 cells,HeLa cells and U 87MG cells ). The apoptosis inducing effect of compound 7 on U 87MG cells was evaluated by flow cytometric Annexin V-FITC/PI staining test. RESULTS:Sixteen triterpenoid saponins were obtained and identified as 3 β-O-β-D-xylopyranosyl-(1→2)-α-L-arabinopyranosyl-oleanolic acid-28-O-α-L-rhamnopyranosyl- (1→4) -β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside(1),3β-O-L-arabinopyranosyl oleanolic acid- 28-O-β-D-glucopyranoside(2),saponin B (3), 163.com oleanolic acid- 3β-O-β-D-glucopyranosyl-(1→2)-α-L-arabino- pyranoside(4),HN-saponin F (5),clematoside S (6),prosapogenin CP 4(7),cussonside B (8),pulsatilla saponin C (9), clemastanoside D (10),3 β-O-β-D-glucopyranosyl-(1→2)-β-L-arabinopyranosyl-hederagenin-28-O-β-D-glucopyranoside(11), ciwujianoside C 3(12),ciwujianoside A 1(13),huzhangoside D (14),kalopanaxsaponin B (15)and hederacolchiside E (16). Compounds 3,4,6-9 displayed inhibitory activities on the proliferation of tumor cells to different extent ,and compound 7 had the strongest activity ;compound 7 induced the apoptosis of U 87MG cell so as to inhibit the proliferation of cancer cells in a time-dependent manner. CONCLUSIONS The obtained 16 saponins are all identified as oleanolane-type ,among which compound 1 is a new compound. The monodesmosidic saponins ,the sugar chain of which attached at C- 3 and a free carboxyl at C- 28, possess stronger antitumor activity than others.

ABSTRACT

Objective:To investigate the correlation between preterm infants with brain injury and the proportion of lymphocyte subsets, especially γδ-T cells in the postnatal peripheral blood, and to determine the predictive potential of γδ-T cells in the early peripheral blood in brain injury.Methods:It was a prospective study involving 106 preterm infants with gestational age less than 34 weeks who were delivered in the Department of Neonatology, the Third Affiliated Hospital of Zhengzhou University from January 1, to June 1, 2021.Relative levels of γδ-T , CD4 + T, CD8 + T, CD3 + T and total lymphocyte subsets in peripheral blood collected within the first 24 hours after birth were measured by flow cytometry.Recruited infants were divided into brain injury group (36 cases) and non-brain injury group (70 cases) according to serial cranial ultrasound and magnetic resonance imaging(MRI) at the corrected gestational age of 36-37 weeks.Differences in general conditions and the proportion of lymphocyte subsets between groups were compared by the t-test or Chi- square test.Patients in brain injury group were further divided into intracranial hemorrhage(ICH) group(8 cases), periventricular leukomalacia (PVL) group (6 cases)and diffuse white matter damage (WMD) group(22 cases). The proportion of lymphocyte subsets among the different groups was compared by One- Way ANOVA, followed by the LSD- t test. Results:The proportion of γδ-T cells in postnatal peripheral blood of preterm infants at 24 hours after birth in brain injury group was significantly lower than that of non-brain injury group [(0.09±0.12)% vs.0.15±0.13)%, t=-2.445, P=0.016]. No significant differences in the proportion of the CD4 + and CD8 + T cell subsets were found between them.Both preterm infants in PVL group and WMD group had a significantly lower proportion of γδ-T cells at 24 hours after birth compared to that of the non-brain injury group [(0.03±0.05)%, (0.07±0.09)% and (0.15±0.13)%], respectively, ( t=-2.190, -2.659, all P<0.05). Conclusions:γδ-T cells in early postnatal peripheral blood may be involved in the development of brain injury in preterm infants and they had early predictive value for preterm infants at high risk of brain injury, especially the leukomalacia and diffuse white matter injury.

ABSTRACT

Objective:To investigate changes in serum C3d and C5b-9 levels in elderly patients with idiopathic membranous nephropathy(IMN)and their correlations with prognosis.Methods:Two hundred thirty-one elderly patients with IMN and 96 non-elderly patients with IMN confirmed by kidney biopsy at the First Affiliated Hospital of Zhengzhou University from January 2015 to May 2017 were enrolled.During the same period, 118 healthy individuals receiving health checkups were included as controls.Patients were divided into the low C3d group( n=112)and the high C3d group( n=113)according to the median level of serum C3d.Serum C3d and C5b-9 levels were measured by enzyme-linked immunosorbent assays. Results:Serum C3d and C5b-9 levels in elderly IMN patients were 0.23(0.15, 0.45)mg/L and 0.28(0.20, 1.23)mg/L, respectively, which were higher than those in healthy controls[0.18(0.13, 0.22)mg/L, 0.22(0.16, 0.26)mg/L, respectively]( Z=-4.261 and -6.213, P<0.001). Serum C3d levels in elderly and non-elderly IMN patients were correlated negatively with the estimated glomerular filtration rate( r=-0.155 and -0.426, P=0.019 and 0.000), but positively with serum creatinine, anti-phospholipase A2 receptor(PLA2R)antibody levels and 24 h urinary protein( r=0.184, 0.326, 0.407, 0.321 and 0.145, P=0.005, 0.001, 0.000, 0.001 and 0.027). Kaplan-Meier survival analysis showed that the cumulative renal survival rate in elderly IMN patients was lower in the high C3d group than in the low C3d group(47.8% vs.70.8%, Log Rank χ2=7.399, P=0.007). Multivariate Cox regression analysis showed that high C3d levels were an independent risk factor for poor renal outcomes in elderly IMN patients( HR=2.288, 95% CI: 1.082-4.839, P=0.030). Conclusions:High serum C3d levels are associated with increases in urinary protein excretion and anti-PLA2R antibody levels, renal function decline, and poor renal outcomes in elderly IMN patients.

ABSTRACT

Objective:To detect serum level of complement factor B (CFB), and to explore its correlations with clinical parameters and prognosis in children with primary IgA nephropathy (IgAN).Methods:A total of 204 children with primary IgAN confirmed by kidney biopsy in the Department of Nephrology of the First Affiliated Hospital of Zhengzhou University from December 2014 to April 2017 were included in IgAN group.During the same period, 84 healthy children were included in healthy control group.Their mean age was (11.0±3.5) years and (10.9±3.2) years, respectively.Patients in IgAN group were divided into low CFB group (102 cases) and high CFB group (102 cases) according to the medium serum level of CFB measured by enzyme-linked immunosorbent assay. Spearman′ s coefficient was employed to analyze correlation amongst various parameters.Multivariable-adjusted Cox proportional ha-zards models were used to evaluate the relationship between serum CFB level and prognosis in children with IgAN. Results:Serum CFB levels were significantly higher in IgAN group than that in healthy control group [290.9 (186.2-453.9) mg/L vs.218.9 (155.0-321.3) mg/L, Z=-3.372, P=0.001]. Serum levels of CFB were negatively correlated with serum albumin ( r=-0.388, P<0.001) and estimated glomerular filtration rate ( r=-0.416, P<0.001), but positively correlated with serum creatinine ( r=0.305, P<0.001) and 24 h urinary protein ( r=0.456, P<0.001) in IgAN group.The incidences of crescents (C1-2) (70.6% vs.29.4%, χ2=34.588, P<0.001) and C 3 deposition (+ + -+ + + ) (63.7% vs.44.1%, χ2=7.892, P=0.005) were significantly higher in high CFB group than those in low CFB group. Kaplan- Meier analysis showed that high CFB levels predicted worse renal outcome in pediatric IgAN patients ( χ2=17.509, P<0.001). Multivariate Cox regression analysis showed that the high CFB level was the independent risk factor for the poor renal outcome ( HR=2.517, 95% CI: 1.284-4.932, P=0.007). Conclusions:High serum levels of CFB are associated with decreased renal function, increased urinary protein excretion, crescentic formation and poor renal outcome in pediatric IgAN patients.

ABSTRACT

Objective@#To analyze the function of essential hypertension′s working memory network by using task-fMRI and independent component analysis (ICA).@*Methods@#According to the enrollment criteria, 24 hypertensive patients and 23 healthy controls (May 2016 to January 2017) in the 900 Hospital of the Joint Service Support Force were collected, who underwent task-state functional MRI data acquisition of N-back by using Siemens 3.0 T MRI. All subjects completed neuropsychological cognitive tests, blood pressure measurements and biochemical tests before MRI. Task-state functional MRI was analyzed by SPM 12, and independent component analysis was performed by GIFT 4.0 software. The independent-samples t-test was used to analyze the maps of the two groups′s task-state fMRI and ICA. The results were adjusted by multiple comparison correction of Alphasim, P<0.05 showed that the difference was statistically significant.@*Results@#Compared with the healthy group, the activation of left superior frontal gyrus and left middle frontal gyrus in hypertension group was enhanced (P<0.05), but there was no obvious weakened activation area. In the independent component analysis, the functional connectivity of left middle frontal gyrus and left anterior central gyrus in hypertension group was significantly lower than that in healthy control group (P<0.05), and there was no significant enhancement of functional connectivity.@*Conclusions@#The working memory network of patients with essential hypertension may change abnormally due to the influence of long-term hypertension. This kind of damage can compensate through the functional enhancement of brain regions, thus maintaining the normal cognitive level of hypertensive patients.

ABSTRACT

Objective:To analyze the clinical features and imaging findings of chest computed tomography (CT) of patients with corona virus disease 2019 (COVID-19), and to provide imaging guidance for early diagnosis and clinical treatment.Methods:A total of 74 patients diagnosed with positive nucleic acid test of nasopharyngeal swab were retrospectively collected from January 23 to February 22, 2020 in the inpatient department of Rui′an People′s Hospital. Their clinical features were analyzed in combination with CT image characteristics.Results:Of the 74 patients, 62 (83.8%) had fever, 59 had abnormalities in CT examinations and 15 patients had no imaging abnormalities. The average interval from onset to CT examination was 4.6 days. Among 59 patients, 58 cases (98.3%) were mainly peripherally distributed, 53 cases (91.4%) had multiple lesions and five cases (8.6%) had single nodules. The main manifestation was ground glass opacities (45 cases, 76.3%). The lesions were mainly distributed in the middle and lower lobe of the lungs, accounting for 76.3% (45 cases). Air bronchogram was shown in 21 cases (35.6%), and reversed halo sign was shown in 10 cases (16.9%). Other rare abnormalities were small cavities in three cases (5.1%), tree-in-bud pattern in one case (1.7%). Intrathoracic lymph node enlargement was found in two cases (3.4%) by re-examination.Conclusion:The CT examination characteristics of COVID-19 patients could play an important role for early diagnosis and follow-up.

ABSTRACT

Objective To investigate the incidence situation of metabolic syndrome (MS) in patients with continuous ambulatory peritoneal dialysis (CAPD),and analyze the correlation between MS and prognosis of patients.Methods The patients who received peritoneal dialysis from June 1,2002 to April 30,2018 and followed up regularly were divided into MS group and non-MS group according to the diagnostic criteria of MS.Follow-up was until July 31,2018.The differences of clinical data,metabolic indexes and clinical outcomes between the two groups were compared.The survival rates of the two groups were compared by Kaplan-Meier survival curve,and the risk factors of all-cause death and cardiovascular disease (CVD) death were analyzed by Cox regression analysis.Results A total of 516 patients with CAPD were enrolled in this study,including 340 males (65.9%)and 176 females (34.1%).Their age was (47.29± 12.20) years.The median follow-up time was 20 (9,39) months.According to the diagnostic criteria of MS,the patients were divided into MS group (210 cases,40.7%) and non-MS group (306 cases,59.3%).At baseline,there was no significant difference in age,educational background,duration of peritoneal dialysis,smoking history and drinking history between the two groups (P > 0.05),but the patients in MS group were more exposed to high glucose peritoneal dialysate (P < 0.05).The body mass index (BMI),blood phosphorus,blood glucose,blood potassium,triglyceride,cholesterol and systolic blood pressure in MS group were significantly higher than those in non-MS group (all P < 0.05),and HDL-C level was significantly lower in MS group than in non-MS group (P < 0.05).There were no significant differences in other indicators between the two groups (P > 0.05).Kaplan-Meier survival curve showed that the cumulative survival rate in MS group was significantly lower than that in non-MS group,and the difference was statistically significant (Log-rank x2=14.87,P < 0.001).If CVD death was taken as the end event,the cumulative survival rate in the non-MS group was significantly higher than that in the MS group (Log-rank x2=14.49,P < 0.001).Multivariate Cox regression analysis showed that MS and high 4 h dialysate creatinine/serum creatinine ratio (4hD/Pcr) were independent risk factor for all-cause death (HR=1.982,95%CI 1.240-3.168,P=0.004;HR=3.855,95%CI 1.306-11.381,P=0.015) and CVD death (HR=2.499,95%CI 1.444-4.324,P=0.001;HR=5.799,95% CI 1.658-20.278,P=0.006) in patients with CAPD.Conclusion The prevalence of MS in patients with CAPD is high,and MS and high 4hD/Pcr are independent risk factor for all-cause and CVD death in CAPD patients.They can be used as valuable indicators to predict the treatment outcomes and long-term prognosis of patients with CAPD.
