RESUMO
OBJECTIVE@#To explore the genetic basis for a child with optic atrophy and global developmental delay.@*METHODS@#A child who had presented at the Guangzhou Women and Children's Medical Center in January 2022 was selected as the study subject. Clinical data were collected. Whole exome sequencing (WES) was carried out for the child. Candidate variant was validated by Sanger sequencing and bioinformatic analysis.@*RESULTS@#The child, a nine-month-old female, had manifested dysopia and global developmental delay. Genetic testing revealed that she has harbored a de novo c.425G>C (p.Arg142Pro) variant of the NR2F1 gene, which has been associated with Bosch-Boonstra-Schaaf syndrome. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was classified as pathogenic (PS2+PM1+PM2_Supporting+PM5+PP3+PP4).@*CONCLUSION@#The c.425G>C (p.Arg142Pro) variant of the NR2F1 gene probably underlay the pathogenesis in this child. Above finding has enriched the genotypic and phenotypic spectrum of the NR2F1 gene.

RESUMO
Although children usually develop less severe disease responding to COVID-19 than adults, little is known about the pathogenesis of COVID-19 in children. Herein, we conducted the plasma proteomic and metabolomic profiling of a cohort of COVID-19 pediatric patients with mild symptoms. Our data show that numerous proteins and metabolites involved in immune as well as anti-inflammatory processes were up-regulated on a larger scale in children than in adults. By developing a machine learning-based pipeline, we prioritized two sets of biomarker combinations, and identified 5 proteins and 5 metabolites as potential children-specific COVID-19 biomarkers. Further study showed that these identified metabolites not only inhibited the expression of pro-inflammatory factors, but also suppressed coronaviral replication, implying that these factors played key roles in protecting pediatric patients from both viral infection and infection-induced inflammation. Together, our study uncovered a protective mechanism responding to COVID-19 in children, and sheds light on potential therapies. TeaserAnti-inflammatory metabolites were highly elevated in the plasma of COVID-19 pediatric patients with mild symptoms.
RESUMO
BackgroundIn response to the current COVID-19 pandemic, it is crucial to understand the origin, transmission, and evolution of SARS-CoV-2, which relies on close surveillance of genomic diversity in clinical samples. Although the mutation at the population level had been extensively investigated, how the mutations evolve at the individual level is largely unknown, partly due to the difficulty of obtaining unbiased genome coverage of SARS-CoV-2 directly from clinical samples. MethodsEighteen time series fecal samples were collected from nine COVID-19 patients during the convalescent phase. The nucleic acids of SARS-CoV-2 were enriched by the hybrid capture method with different rounds of hybridization. ResultsBy examining the sequencing depth, genome coverage, and allele frequency change, we demonstrated the impeccable performance of the hybrid capture method in samples with Ct value < 34, as well as significant improvement comparing to direct metatranscriptomic sequencing in samples with lower viral loads. We identified 229 intra-host variants at 182 sites in 18 fecal samples. Among them, nineteen variants presented frequency changes > 0.3 within 1-5 days, reflecting highly dynamic intra-host viral populations. Meanwhile, we also found that the same mutation showed different frequency changes in different individuals, indicating a strong random drift. Moreover, the evolving of the viral genome demonstrated that the virus was still viable in the gastrointestinal tract during the convalescent period. ConclusionsThe hybrid capture method enables reliable analyses of inter- and intra-host variants of SARS-CoV-2 genome, which changed dramatically in the gastrointestinal tract; its clinical relevance warrants further investigation.
RESUMO
Objective:To analyze the viral nucleic acid and cytokines in 12 children with 2019-nCoV infection.Methods:Clinical and laboratory data of the children diagnosed with 2019-nCoV infection in Guangzhou Women and Children′s Medical Center from January to April 2020 were retrospectively analyzed. Throat and anal swabs were collected on alternate days for the detection of 2019-nCoV nucleic acid by fluorescence quantitative PCR. Flow cytometry was used to detect serum cytokines including IFN-γ, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-17A, IL-17F, IL-22, TNF-α and TNF-β during the early (both throat and anal swab tests were positive), the intermediate (throat swab test was negative, while anal swab test remained positive), and the convalescence (both throat and anal swab tests were negative) stages of infection.Results:A total of 12 children were enrolled in this study. The male-to-female ratio was 5∶1. The average age was (7.0±4.3) years. There were two asymptomatic, five mild and five common cases. No severe or critical cases were involved. Initially, throat and anal swab nucleic acid tests were simultaneously positive in nine children newly diagnosed in our hospital and the median time of viral shedding in throat swab was longer than that in throat swab [32 (4.5, 45.0) d vs 3 (2, 9) d, Z=11.0, P=0.010]. The median difference of viral shedding time between anal swab and pharyngeal swab was 25.5 (1.5, 42.8) d. The overall levels of serum cytokines IL-17A, IL -4 and IL-5 in different stages of the disease (early, intermediate and convalescence stage) were statistically different ( Z or F, P values were 8.33, 0.016; 5.36, 0.010 and 6.56, 0.004, respectively), and a significant increase was observed in the intermediate stage of infection. IL-17F, IL-2 and IL-22 were all increased during the infection, but there was no significant statistical difference among the three stages ( P>0.05). Conclusions:It was noted that intestinal viral shedding needed a longer time. Although the infectivity has not been determined, higher requirements have been put forward for disease prevention and control. Cytokines secreted by Th2 and Th17 cells were involved in the immune response in children with non-severe 2019-nCoV infection. Monitoring viral shedding and cytokine changes in pediatric patients would be conducive to disease assessment.
RESUMO
Objective@#To investigate the clinical manifestations, diagnosis, and treatment of H1N1 influenza A-associated encephalopathy (IAE) in children.@*Methods@#The clinical manifestations, laboratory tests, cranial magnetic resonance imaging (MRI), electroencephalography (EEG) examinations and treatments of seven children with H1N1 IAE hospitalized in Guangzhou Women and Children′s Medical Center from December 2018 to January 2019 were retrospectively analyzed.@*Results@#Five of the seven children with H1N1 IAE were female. The age at admission was 4 years and 5 months (range 7 months-9 years). Neurological symptoms occurred simultaneously or early (0-3 days) after the flu-like symptom appeared. The main clinical manifestations of neurological symptoms were seizures (repeated seizures in five cases and status convulsion in two cases, including one case of unexpected fever and repeated seizures in a nine-year old girl) accompanied with altered consciousness (drowsiness in five cases and coma in two cases). Cranial MRI in three cases displayed multifocal lesions, mainly in the bilateral thalamus, brainstem and cerebellar hemisphere. MRI also showed reversible splenial lesion in the corpus callusumin in three cases. EEG tracings were characterized by diffuse slow wave activity in four cases, and status epilepticus was monitored in one case. All the 7 cases were treated with oral oseltamivir. Three cases were treated with pulsed methylprednisolone and intravenous immunoglobulin. One case was treated with intravenous immunoglobulin alone and all the patients received oral oseltamivir. All the patients survived, with three patients had minor neurological sequelae at discharge.@*Conclusions@#The main clinical manifestations of H1N1 IAE are seizures and altered consciousness. Cranial MRI combined with EEG is helpful for early diagnosis. Intravenous immunoglobulin and (or) methylprednisolone should be considered for severe cases.
RESUMO
Objective To explore the clinical characteristics including the morbidity, clinical manifestation, and pathogens of late-onset sepsis (LOS) in very low birth weight (VLBW) infants in neonatal intensive care unit (NICU). Methods Clinical data of all VLBW infants in NICU from January 2011 to December 2013 were collected. According to the results of blood culture, the VLBW infants diagnosed with LOS were divided into confirmed LOS group and clinical LOS group. The morbidity, clinical manifestations, common pathogens, and drug sensitivity of LOS were retrospectively analyzed. Results In 226 VLBW infants, there were 117 cases of LOS with the morbidity at 51.8%. Forty-five infants were confirmed to have LOS by blood culture, accounting for 19.9% (45/226); another 72 infants were diagnosed with clinical LOS, accounting for 31.9% (72/226). The rates of tachycardia and temperature fluctuation in confirmed LOS group were higher than those in clinical LOS group, and there were significant differences (P<0.05). There were 51 strains of pathogenic bacteria, with 32 Gram-negative bacteria (62.7%), 16 Gram-positive bacteria (31.4%), and 3 fungi (5.9%).The common pathogenic bacteria were Klebsiella pneumoniae and coagulase negative Staphylococcus,the most of which were multidrug-resistant bacteria.Conclusions The incidence of LOS in VLBW infants is high. The main clinical manifestations are sudden changes in breathing, heart rate, mental state, and skin color. Although these manifestations are not specific,they could serve as early warning.The common pathogenic bacteria are Klebsiella pneumoniae and coagulase negative Staphylococcus,and both of them are multidrug resistant.
RESUMO
Objective To investigate effects of different ventilation methods during pulmonary surfactant(PS) administration on cerebral oxygen metabolism in preterm infants with neonatal respiratory distress syndrome.Methods Newborns met the inclusion criteria were enrolled into this study,and they were randomly divided into manual group and mechanical group.During PS administration,the proximal end of the tracheal tube was connected to a bag valve mask device in the manual group or a mechanical ventilator in the mechanical group.Brain near infrared spectroscopy monitoring was carried out to detect the cerebral oxygen saturation(ScO2),and the mean arterial blood pressure (MABP) was simultaneously recorded.Results For all 49 preterm infants,PS was administered to preterm infants with severe respiratory distress syndrome treated with mechanical ventilation,including 24 cases of manual ventilation and 25 cases of mechanical ventilation.The left cerebral ScO2 and correlation coefficient of ScO2 and MABP(rScO2-MABP) showed no difference in both groups before PS administration.During administration,ScO2 dramatically increased in both groups [manual group:(85.88 ± 5.54) % vs.(77.31 ± 5.40) %,t =5.521,P =0.000;mechanical group:(83.88 ± 3.18) % vs.(76.53 ±4.38)%,t =6.741,P =0.000],and gradually decreased after administration,the level of ScO2 didn't return to the baseline till the 2nd 5 minutes after PS administration [manual group:(79.25 ± 3.02) % vs.(77.31 ± 5.40) %,t =1.560,P =0.220;mechanical group:(78.59 ± 3.45) % vs.(76.53 ± 4.38) %,t =1.832,P =0.074].The same trend of ScO2 change rate was shown simultaneously in both groups.The rScO2-MABP markedly increased during administration in both groups (manual group:2.34 ±0.16 vs.1.86 ±0.21,t =9.022,P =0.000;mechanical group:2.12 ± 0.15 vs.1.87 ±0.21,t =4.810,P =0.000).The rScO2-MABt,in mechanical group rapidly decreased to baseline during the 1st5 minutes (1.84 ± 0.18 vs.1.87 ± 0.21,t =0.538,P =0.635) but went back to baseline in manual group during the 2nd 5 minutes(1.84 ±0.19 vs.1.86-0.21,t =0.350,P =0.809).Change rates of rScO2-MABP were markedly higher in manual group than those in mechanical group during the 1 st 5 minutes (1.15 ± 0.13 vs.1.00 ± 0.15,t =4.943,P =0.000).Conclusions ScO2 could be affected transiently by PS administration with different methods of ventilation.The effect on cerebral autoregulation in mechanical group is shorter than that in manual group.
RESUMO
Objective To observe the changes of abdominal oxygen saturation in very low birth weight infants (VLBWI)with feeding intolerance (FI)within 1 4 days after birth monitored by near infrared spectroscopy (NIRS).Methods VLBWI fitting entry criteria were enrolled into this study.NIRS monitoring was carried out to detect cerebral oxygen saturation (ScO2 )and abdominal oxygen saturation (SsO2 ).Data were analyzed between FI infants and feeding tolerance (FT)infants.FI was defined as follows:gastric residual of more than 50% of the previous feeding volume;emesis or abdominal distention or both;decrease,delay or discontinuation of enteral feedings. Results 93 VLBWI were enrolled.52 cases(55.91 %)presented with FI,including 29 cases(31 .1 9%)of gastric residual increasing and 23 cases(24.73%)of emesis with or without abdominal distention within 1 4 days after birth. The levels of SsO2 and SsO2 /ScO2 showed no differences in infants with FT and with FI within 24h after birth (P >0.05).The change rates of the median of SsO2 and SsO2 /ScO2 in FT infants were similar during 1 4 days (P >0.05).While both the change rates of SsO2 and SsO2 /ScO2 were markedly decreased 1 day before and the day of FI (P <0.01 ).The decreasing degree of SsO2 was similar between infants with gastric residual increasing and infants with emesis with or without abdominal distention[(1 6.2 ±5.1 )vs (1 7.4 ±3.6)%,t =0.733,P =0.476]. Conclusion Abdominal oxygen saturation measured by NIRS may be a useful method for infants adjusting the feeding plan.
RESUMO
Objective To evaluate the effect of caffeine citrate on oxygen metabolism in brain and intestine in premature infants with neonatal respiratory distress syndrome (NRDS).Methods Preterm infants aged 30-34 weeks with NRDS admitted in Guangzhou Women and Children's Medical Center during May 2015 and April 2016 were enrolled.They were administrated with maintainance dose of caffeine citrate at the 2nd day after birth.The oxygen metabolism in brain and intestine 1 h before,during and after the administration were recorded by near infrared spectroscopy.Results The cerebral oxygen saturation (ScO2) showed a less significant change before,during and after treatment.While a marked increase was seen in intestinal oxygen saturation (SsO2) during and after caffeine citrate administration,as well as the change of SsO2/ScO2 than before.SsO2/ScO2 was dramatical higher in infants with nasal continuous positive airway pressure (nCPAP) than in those with incubator oxygen supply and mechanical ventilation during and after caffeine citrate treatment than before.Conclusion Caffeine citrate may improve the delivery of oxygen and may increase the oxygenation in local tissues for preterm infants with NRDS,especially for infants with nCPAP.
RESUMO
Objective To explore the correlation between the expression of IL-17A and the degree of spleen damage in acute mouse cytomegalovirus(MCMV) disseminated infection in vivo and to understand the mechanism about how IL-17A involved in the pathological damage of the spleen in MCMV infection.Methods An acute disseminated MCMV infection model was established in mice.BALB/c mice were randomly divided into two groups.Mice in group one were infected with MCMV Smith to establish disseminated infection.Mice in another group were sham-infected control.Three mice from each group were randomly chosen to be sacrificed on days 3,7,14 and 28 after the infection.Viral titers in spleen tissues were determined using a standard plaque assay.The expression of IL-17A mRNA and MCMV mRNA in the splenocytes were measured by RT-PCR.The expression of IL-17A in spleen tissues was observed by immunohistochemical staining.The pathology of the infected mice was assessed by histological examination of H&E stained spleen sections.Results Viral titers and MCMV mRNA in the spleen peaked on day 3,but quickly diminished on day 7.Virus was no longer detectable in the spleen on day 14 after the infection.The expression of IL-17A mRNA was significantly increased during the acute infection and reached the highest level on day 14,then decreased on day 28.It is significantly higher than that of the mock infection group.Immunohistochemistry assay also indicated that the expression of IL-17A in spleen tissue gradually increased to climax on day 14,then decreased on day 28.Accordingly,the pathological damages of spleen tissue in the infected mice deteriorated until day 14,then showed signs of recovery on day 28.The most severe pathological injury of spleen tissue and the highest expression of IL-17A appeared in the same period of time.Conclusion Our results showed a close correlation between IL-17A and the pathological damage in spleen.Thus,IL-17A may contribute to the spleen pathological damage during the acute disseminated MCMV infection.
RESUMO
Objective To study the time-and dose-effect of mitochondrial DNA (mtDNA) 4934 bp and 4977 bp deletions in the human peripheral blood irradiated by137 Cs γ-rays,and to evaluate its implication in biological dosimetry.Methods The peripheral blood from five healthy adults was collected and irradiated with γ-rays.The peripheral blood of one healthy adult was irradiated with 5 Gy and cultured for 2,24,48 and 72 h after irradiation.The peripheral blood from the other four healthy adults was cultured for 2 h after 0,0.5,1,2,5 and 10 Gy irradiation.The peripheral blood mtDNA 4934 bp and 4977 bp deletions were detected by real-time polymerase chain reaction and gel electrophoresis.The doseeffect curves were fitted using Curve Expert 1.4 Software.Results mtDNA 4934 bp and 4977 bp deletions were induced at 2 h post-irradiation and the mtDNA 4934 bp deletion had relative high levels at 2 h and 48h after radiation (t =10.782 and 8.966,P < 0.05),and mtDNA 4977 bp deletion reached the highest level at 48 h after radiation (t =7.433,P <0.05).mtDNA 4934 bp (t =2.895-8.105,P <0.05) and 4977 bp deletion (t =3.006-7.715,P <0.05) irradiated at 0.5-10 Gy increased with a dosedependent manner.The incidence of mtDNA 4977 bp deletion was higher than that of 4934 bp deletion for those samples exposed with same dose of irradiation,especially at 10 Gy (t =2.919,P < 0.05),which suggested that 4977 bp deletion might be more sensitive than 4934 bp deletion at high dose.But larger individual differences were found in 4977 bp deletion compared with 4934 bp deletion.The dose-effect equations for 4934 bp deletion and 4977 bp deletion were Y1 =1.178 + 0.1219D (R2 =0.9269) and Y2 =1.2578 +0.1933D (R2 =0.9016),respectively.Conclusions The induction of mtDNA deletion was correlated with radiation dose,and thus it may be a available method for biological dose estimation and prognostic evaluation.
RESUMO
Objective To investigate the usefulness of calcium and phosphorus supplementation in parenteral nutrition for extremely low-birth-weight (ELBW) infants.Methods According to the inclusion criteria,66 ELBW infants hospitalized after birth in neonatal ward of Tongji Hospital from June 2009 to December 2012 were divided into three groups with random number table:28 infants in the first group were treated with parenteral nutrition without calcium and phosphorus supplementation,21 infants in the second group were treated with parenteral nutrition with calcium supplementation only,and 17 infants in the third group was treated with parenteral nutrition with calcium and phosphorus supplementation.The blood levels of ionic calcium,blood phosphorus,and urine calcium and creatinine were determined once a week (total of 4 times).The speed of sound (SOS) was detected for shin bones by quantitative ultrasound at the date of admitting and the end of 4weeks.Results After administrations of supplementation,the blood levels of ionic calcium in the second group were significantly higher than those in the first group [on the 14th day,(1.82 ± 0.35) mmol/L vs.(1.14 ±0.47) mmol/L,t=5.800,P=0.005;onthe21stday,(1.77±0.45) mmol/Lvs.(1.07±0.43) mmol/L,t=5.492,P=0.004; on the 28th day,(1.61±0.58) mmol/Lvs.(0.92±0.44) mmol/L,t=4.556,P=0.025].The blood levels of ionic calcium in the third group were also significantly higher than those in the first group [on the 14th day,(1.55 ± 0.30) mmol/L vs.(1.14 ± 0.47) mmol/L,t =3.570,P =0.001 ; on the 21st day,(1.58 ±0.38) mmol/L vs.(1.07 ±0.43) mmol/L,t =4.151,P=0.000; on the 28th day,(1.55 ±0.35) mmol/L vs.(0.92 ±0.44) mmol/L,t =5.302,P =0.003].The blood levels of phosphorus were significantly elevated in the third group compared with those in the first group [on the 14th day,(1.86 ±0.10) mmol/L vs.(1.65 ±0.17) mmol/L,t=5.217,P=0.012; on the21st day,(1.88 ±0.14) mmol/Lvs.(1.61 ±0.13) mmol/L,t =6.442,P=0.003; on the 28th day,(1.89 ±0.15) mmol/L vs.(1.58 ±0.14) mmol/L,t =6.891,P =0.000] and the second group [on the 14th day,(1.86 ± 0.10) mmol/L vs.(1.53 ±0.15) mmol/L,t =8.100,P=0.000; on 21st day,(1.88 ±0.14) mmo/Lvs.(1.57 ±0.14) mmol/L,t =6.787,P =0.000; on the 28th day,(1.89 ± 0.15) mmol/L vs.(1.62 ± 0.18) mmol/L,t =5.043,P =0.000].The calcium-to-phosphorus ratios markedly increased in the second group compared with those in the first group (on the 14th day,0.69 ±0.18 vs.0.33 ±0.14,t =7.601,P =0.000; on the 21st day,0.66±0.16 vs.0.37 ±0.14,t =6.62,P=0.001 ; on the 28th day,0.62 ±0.15 vs.0.39 ±0.12,t =5.776,P =0.005) while declined in the third group (on the 14th day,0.14 ± 0.10 vs.0.33 ± 0.14,t =5.294,P =0.010; on the 21st day,0.13 ± 0.12 vs.0.37 ± 0.14,t =6.102,P =0.002; on the 28th day,0.12 ± 0.11 vs.0.39 ± 0.12,t =7.711,P =0.000).The third group showed significantly increased SOS values than those in the first and second groups [(381 ± 87) m/s vs.(135 ± 87) m/s,t =9.815,P =0.000;(381 ±87) m/s vs.(146 ±68) m/s,t =9.774,P=0.000].Conclusions Proper supplementation of calcium and phosphorus via parenteral nutrition can achieve increased bone mineral contents and stable blood ionic calcium and phosphorus levels,and avoid hypercalciuria in ELBW infants.PN therapy with calcium and phosphorus supplementation in ELBW infants needs further studies.
RESUMO
Objective To investigate the nature of Th17 cells in murine cytomegalovirus(MCMV)infection during the acute stage,we characterized the frequency of IL-17A-producing CD4 T cells and the level of Th17 cytokines,IL-17A,in MCMV-infected mice.Methods BALB/c mice were randomly divided into two groups.One was infected with MCMV Smith for establishing disseminative infection; the other was sham-inoculated control.On day 3,7,14 and 28 of the experiment,three mice of each group were randomly chosen to be killed separately.Real-time PCR was used to detect MCMV loads in organs of MCMV-infected mice,the pathology of spleen was observed by HE staining.The frequency of CD4+IL-17A+ T cells in total splenocytes of mice was detected by flow cytometry.The level of IL-17A in culture supernatants of splenocytes was measured by double antibody sandwich ELISA.Results MCMV loads in salivary gland reached the peak on day 14 after MCMV infection,the most severe spleen injury was also shown on day 14,the frequencies of CD4+IL-17A+ T cells in total splenocytes increased significantly( all P<0.01 ) in MCMV-infected mice than those in controls,and reached the peak on day 14 ( 1.14% ±0.09% vs 0.19% ±0.04%,t =17.551,P=0.000).The levels of MCMV-specific IL-17A in culture supernatants were increased dramatically in MCMV-infected mice than those in controls on day 14 [ (81.98± 12.37) pg/ml vs (44.96±8.44)pg/ml,t=4.281,P=0.006].In MCMV-infected mice,correlation was positive between the levels of MCMV-specific IL-17A in culture supernatants and MCMV loads in salivary gland tissues (r=0.54,P<0.05 ),the levels of IL-17 A in culture supernatants were higher in more severe spleen injury.Conclusion Thl7 cells and IL-17A were involved in the immunity response during acute MCMV infection.They may correlate with the persistence of MCMV and the pathology of spleen in infected mice.
RESUMO
ObjectiveTo observe the changes of AIM2 ( absent in melanoma 2) inflammasome during early murine cytomegalovirus (MCMV) infection.MethodsBALB/c mice were randomly divided into two groups.One was infected with MCMV Smith for establishing disseminated infection,the other was sham-inoculated control.On days 1,3,5 and 7 of the experiment,three mice of each group were randomly chosen to be killed separately.The expression of AIM2,ASC and caspase-1 in splenic macrophages was detected by Western blot,the levels of IL-1β and IL-18 in sera were measured by double antibody sandwich ELISA,and the viral titers in salivary gland tissues were quantified by a standard plaque assay.Results The MCMV titers in salivary gland tissues were gradually increased in MCMV-infected mice on days 3,5 and 7,while the expressions of AIM2 in macrophages were began to increase on day 1 and significantly increased and reached the highest level on day 3 but gradually decreased afterwards.The relative intensity of AIM2 on day 3 differed significantly between the MCMV-infected mice and the controls (1.121±0.243 vs 0.240±0.046,P<0.01,t test),as did ASC ( 1.318±0.333 vs 0.248±0.090,P<0.01 ) and caspase-1 ( 1.085±0.243 vs 0.247±0.064,P<0.01 ).Meanwhile,the levels of IL-1β and IL-18 in MCMV-infected mice were (112.72±5.20) pg/ml and (42.74±4.23) pg/ml,and the levels were significantly higher (P<0.01 ) than those in controls [ (47.86±4.35) pg/ml and (22.60±2.82) pg/ml].ConclusionThese results demonstrate that AIM2 inflammasome is activated in macrophages during early MCMV infection and could be as a therapeutic target for CMV-induced diseases.
RESUMO
Objective To discuss the intervention effect of cognition therapy for perioperative patients of digestive tract with depression and/or anxiety symptoms.Methods 135 patients with digestive tract operation were randomly divided into intervention group and non-intervention group.The patients in intervention group accepted cognition therapy.The Mores of SDS and SAS,the curative effect and hospitalized time were compared among the two groups and the norlns of our country at last.Results (1)The scores of SDS and SAS in the two group patients in pre-operation were no difference(P>0.05),but all were significantly higher than those of the norms of our country(P<0.01).It indicated that patients have evident depression and/or anxiety symptoms pre-operation. (2)Compared with pre-operation,the scores of SDS and SAS in the intervention group patients showed significantly lower after operation(P<0.01),which returned to the norms of our country(P>0.05),and showed lower than those of the non-intervention group predominantly (P<0.01).This indicated that cognition therapy can relieve the depression and/or anxiety symptoms of the perioperative patients.(3)Though the therapeutic effect of the two group are similar(P>0.05),but the hospitalized fime decurated in the intervention group predominantly(P<0.01).Conclusion The periopexative patients of digestive tract had obvious depression and/or anxiety symptoms.Cognition therapy could relieve the depression and/or anxiety sympmms of the perioperative patients,this was helpful for patients to recover early.
