RESUMEN

Objective To investigate the clinical efficacy and safety of nivolumab(PD-1 inhibitor)in combination with lenvatinib and FOLFOX regimen[5-fluorouracil(5-FU),oxaliplatin(L-OHP),and calcium folinate(LV)]in the treatment of intermediate and advanced hepatocellular carcinoma(HCC)via hepatic arterial infusion chemotherapy(HAIC).Methods A total of 160 patients with intermediate and advanced HCC admitted to the Second Affiliated Hospital of Guilin Medical University from January 2021 to January 2023 were randomly divided into the control group and the observation group,with 80 patients in each group,using a random number table.The control group received once-daily oral lenvatinib and intravenous carrizumab infusions for 12 weeks as part of transcatheter arterial chemoembolization(TACE)therapy.The observation group was administered with FOLFOX regimen via HAIC chemotherapy,plus intravenous infusion of carrizumab for 12 weeks and once-daily oral lenvatinib.All the patients were followed up regularly.The clinical efficacy was evaluated using the mRECIST criteria.The objective response rate(ORR),disease control rate(DCR),overall survival(OS),progression-free survival(PFS),and incidence of adverse reactions were compared between the two groups.Results There were no significant differences in the objective response rate and incidence of adverse reactions between the groups.The disease control rate,overall survival,and progression-free survival in the observation group were significantly higher than those in the control group(P<0.05).Conclusions The FOLFOX-HAIC regimen in combination with nivolumab and lenvatinib is safe and effective for the treatment of intermediate and advanced HCC,without adverse reactions.It can prolong the overall survival and progression-free survival,and improve the patient's quality of life.

RESUMEN

Objective To investigate the effect of auditory brainstem response(ABR)in clinical detection and severity assessment of autism spectrum disorder(ASD)in children with normal hearing.Methods ① A total of 55 autistic children(110 ears)with normal hearing and 55 children(110 ears)with typical development(TD)who did not differ in sex composition ratio and average monthly age were divided into four sub-groups according to age:≤24 months group(22 ears),25～36 months group(40 ears),37～48 months group(28 ears)and＞48 months group(20 ears).The ABR latencies and interpeak latencies were compared between ASD children and age-matched TD children.② ASD children were graded by severity according to the Diagnostic and Statistical Manual of Mental Dis-orders(DSM-V),and the correlations between the ABR latencies and interpeak latencies in autistic children with normal hearing and the severity grading were studied.Results ① No statistically significant differences in ABR wave latencies and interpeak latencies were found in autistic children with normal hearing under 24 months of age compared to age-matched TD children(P＞0.05).② Compared with children with TD,autistic children with nor-mal hearing at 25～36 months of age had significantly longer wave Ⅲ latencies and the interpeak latencies of Ⅰ-Ⅲ andⅠ-Ⅴ;the significantly longer wave Ⅲ,Ⅴ latencies,the interpeak latencies of Ⅰ-Ⅲ,Ⅲ-Ⅴ and Ⅰ-Ⅴ in autistic chil-dren with normal hearing at 37～48 months of age.Autistic children with normal hearing in the＞48 months group had significantly longer wave Ⅴ latencies and interpeak latencies of Ⅲ-Ⅴ,Ⅰ-Ⅴ than age-matched TD children(P＜0.05).③ The higher the ASD severity grading the longer the wave Ⅲ and V latencies and the longer interpeak latencies of Ⅰ-Ⅲ,Ⅲ-Ⅴ,and Ⅰ-Ⅴ(P＜0.05).Conclusion Differences in the level of auditory brainstem pathway de-velopment emerged at 25 months of age,and autistic children with normal hearing had significantly lower levels of auditory brainstem development than age-matched TD children.There were correlations between the latencies and interpeak latencies of ABR in autistic children with normal hearing and the severity grading.

RESUMEN

OBJECTIVE: To evaluate the effectiveness and safety of Xuebijing injection (XBJ) on coronavirus disease 2019 (COVID-19) in patients. METHODS: Related studies on multiple biological databases and websites were searched up to December 11, 2021 without language and publication time restrictions. Review Manager V.5.3 and Stata 14 software were used for data analysis. RESULTS: Seven studies were finally included. The Metaanalysis showed that compared with the routine treatment alone, XBJ combined with the routine treatment can reduce the 28day mortality ( = 0.3, 95% : 0.12, 0.74), Creactive protein ( = -12.8, 95% : -23.13, 3.46), erythrocyte sedimentation rate ( = -9.32, 95% : -14.66, -3.98) and interleukin-6 (S = -0.6, 95% : -1.04, -0.17) levels and increase the leukocyte ( = 0.73, 95% : 0.42, 1.04) and lymphocyte count ( = 0.18, 95% : 0.07, 0.29) in peripheral blood; additionally, it has no obvious side effects ( = 1.11, 95% : 0.65, 1.9). There was no evidence that the XBJ combined therapy can improve the nucleic acid conversion rate and computed tomography improvement rate of COVID19 patients. CONCLUSIONS: Preliminary evidence suggests that XBJ combined with routine treatment seems to be more effective than routine treatment for patients with COVID19. Limited by the number and quality of included papers, this finding still needs further validation by more studies.

RESUMEN

Objective:To explore the value of MRI signs in assessing the presence or absence of hernia sacs in fetuses with congenital diaphragm hernia.Methods:MRI images of 57 patients with congenital diaphragm hernia confirmed by postpartum surgery were analyzed from November 2016 to December 2020 in Xinhua Hospital, Shanghai Jiao Tong University School of Medicine, with a gestational age of 20－40 (28±5) weeks. In postpartum surgery, 18 cases were found with hernia sacs (hernia sac group) and 39 cases without hernia sacs (hernia-free group). Seven MRI signs were analyzed, including hernia peripheral enveloping sensation, smooth lung-hernia interface, crescent-shaped lung compression, residual lung tissue on the affected side, heart displacement, effusion above the lung-hernia interface and effusion below the lung-hernia interface. The differences in MRI signs between the hernia sac and hernia-free groups were compared using the χ 2 test or Fisher′s exact probability method. The diagnostic efficacy of each sign was calculated. The MRI signs with statistical differences between the two groups were included in the predictive integration model, and 1 point was scored for each sign, the imaging score of each fetus was calculated, and the efficacy of imaging points in diagnosing the presence or absence of hernia sacs was assessed by the subject manipulation receiver operating characteristics (ROC) curve. Results:There were statistically significant differences in 5 MRI signs between the hernia sac and the hernia-free groups, namely hernia peripheral enveloping sensation (χ2=25.74, P<0.001), smooth lung-hernia interface (χ2=48.20, P<0.001), crescent-shaped lung compression (χ2=57.00, P<0.001), residual lung tissue on the affected side (χ2=12.14, P<0.001) and effusion above the lung-hernia interface (χ2=4.31, P=0.022). Among them, the sign of crescent-shaped lung compression had the highest diagnostic efficacy, and the sensitivity, specificity and accuracy all were 100%. Five statistically significant MRI signs were included in the predictive integration model, and the area under the ROC curve was 0.999, the sensitivity was 100%, the specificity was 94.9%, and the optimal threshold was 2 points. Conclusion:Fetal MRI signs and predictive integration model can effectively identify the presence or absence of hernia sacs in fetuses with congenital diaphragm hernia, which has certain clinical significance.

RESUMEN

The aim of this study is to explore the genotype and hearing phenotype of deaf infants with mutation of gene. Subjects were 121 infants with gene mutations who were treated in the Children's Hearing Diagnosis Center of Beijing Tongren hospital. All subjects were accepted to undertake the universal newborns hearing screening（UNHS） and series of objective audiometry, including auditory brainstem response, distortion product otoacoustic emission, auditory steady-state response and other audiological tests. All subjects were screened for nine pathogenic variants in four genes or all exons of the gene, and then were diagnosed as infants with gene mutations. Initially, analyzing their genotypes and hearing phenotypes generally. Then, the subjects were divided into two groups according to the genotypes: T/T group（truncated/truncated mutations, 89 cases） and T/NT group（truncated/non-truncated mutations, 32 cases）. Chi-square test was used to analyze the results of UNHS, hearing degree, audiogram patterns and symmetry/asymmetry of binaural hearing phenotype. Eventually, analyzing the results of UNHS. The most common truncated mutation was c.235delC（64.88%, 157/242） and the most common non-truncated mutation was c.109G>A（11.16%, 27/242）. The homozygous mutation of c.235delC/c.235delC was the dominant in T/T group（38.84%, 47/121）, and the compound heterozygous mutation of c.235delC/c.109G>A was the dominant in T/NT group（18.18%, 22/121）. 81.82%（99/121） of subjects failed in UNHS, including 74.38%（90/121） with bilateral reference, 7.44%（9/121） with a single pass. The refer rate of UNHS of group T/T and T/NT were 86.52%（77/89） and 68.75%, respectively. There was a statistically significant difference between the two groups（0.05）. In this study, c.235delC/c.235delC homozygous mutation was dominant in T/T group and c.235delC/c.109G>A heterozygous mutation was dominant in T/NT Group. The hearing phenotypes in T/T group were mostly bilateral asymmetric severe hearing loss, and those in T/NT Group were bilateral symmetric mild to moderate hearing loss, special attention should be paid to the audiological characteristics of different genotypes.

RESUMEN

Newborn hearing screening is an effective method for early detection of hearing loss, however, it is not able to detect delayed-onset hearing loss. By exploring the etiology of delayed-onset hearing loss in children, it can provide a clinical basis for early detection of delayed-onset hearing loss. Mutations in SLC26A4, mitochondrial, GJB2 and other genes, enlarged vestibular aqueduct, congenital cytomegalovirus infection, extracorporeal membrane oxygenation, and auditory neuropathy et al were more commonly reported risk factors. In this paper, the risk factors related to delayed-onset hearing loss, which are divided into 5 categories: genetic mutation, abnormal inner ear malformation, perinatal factors, auditory neuropathy and no identifiable cause, are reviewed and analyzed.
