Objective To know the feasibiliy and the effects of shorten preoperative fasting time for patients with digital cerebral angiography. Methods Divided 110 patients with digital cerebral angiogra-phy into the observation group and the control group according to their sequence enter the hospital. Routine fasting method was used in the control group, shorten fasting time was used in the observation group, com-pared the incidence rate of fasting-related complications between the two groups. Results The incidence rote of belly discomfort, thirstily, strvation and hypoglyeemic during the digital cerebral angiogrsphy in the con-trol group was significant higher than those of in the observation group, while there were no significant difference about the incidence rate of postoperative complication between the two groups. Conclusions For patients with digital cerebral angiography can shorten the preoperative fasting time properly, which can avoid certain complieaitons.

OBJECTIVE: To explore the clinical phenotype and genetic diagnosis of a patient featuring secondary amenorrhea, breast dysplasia and mental retardation. METHODS: Peripheral venous blood samples were collected from the patient and her family members and subjected to G-banding karyotyping and single nucleotide polymorphism array (SNP-array) analysis. RESULTS: The patient was found to have a karyotype of 46,X,der(X)(12qter→ 12q22::Xq23→ Xpter)mat, her mother had a karyotype of 46,X,t(X;12)(Xpter→ Xq23::12q22→ 12qter;12pter→ 12q22::Xq23→ Xqter), while her father and brother were both 46,XY. SNP-array analysis suggested the patient to be arr[hg19]12q22q24.33(94 792 972-133 777 562)× 3, Xq23q28(108 786 070-155 233 098)×1. CONCLUSION The abnormal phenotypes of the patient can probably be attributed to the presence of Xq23-qter deletion and 12q22-qter duplication, both have derived from her mother's balanced t (X;12) translocation.

Objective To investigate the expressions of IgG,Gab2 and PTEN in human gliomas and analyze their relationship with patient prognosis. Methods Immunohistochemistry was performed to detect the expressions of IgG,Gab2 and PTEN in 55 cases of gliomas and 20 cases of normal brain tissues. The mRNA expression of IgG in glioma tissues was detected by in situ hybridization. Results IgG protein and IgG mRNA were expressed in glioma tissues. IgG,Gab2,PTEN expression rate in normal brain tissues was significantly different to that in glioma-tissues(5.0%vs. 69.0%,5.0%vs. 52.7%,and 85.0%vs. 25.5%,P<0.05). Expression of IgG was positively related with expression of Gab2 in glioma(r = 0.3124,P < 0.05),IgG and PTEN expression were negatively related with each other(r=-0.422,P<0.05). Conclusions IgG and Gab2 are highly expressed in glioma. The expression of PTEN was downregulated in glioma. IgG,Gab2 and PTEN might be involved in the development of glioma.

Objective To compare the efficacy and safety between whole brain radiotherapy (WBRT) and WBRT combined with temozolomide (TMZ) in the treatment of non-small cell lung cancer with brain metastases.Methods According to the retrieval strategy,the Chinese and English literatures before February 2018 were retrieved from EMbase,Cochrane,PubMed,Wanfang database,Chongqing VIP and CNKI,The target literatures were selected according to the inclusion and exclusion criteria,The quality of the included studies and extracted data was independently assessed by 3 researchers,The RevMan 5,3 and STATA 12,0 software was used for statistical analysis,The objective remission rate (ORR),the total survival period (OS),the progression-free survival (PFS),and the side effects of chemotherapy were evaluated.Results In total,17 trials consisting of 1128 patients were included,The results of Meta-analysis demonstrated that compared with the WBRT group,the ORR was significantly higher (OR=2.54;95％CI:1.93-3.36;P＜0.001),the PFS was significantly longer (MS R=1.329;95％CI:1.143-1.545;P＜0,001),and the incidence of hematological toxicity (OR=3.44;95％CI:1.63-7.26;P＜ 0.05) and the gastric intestinal reaction (OR=1.69;95％CI:1.24-2.31;P＜0.05) was significantly higher in the WBRT+TMZ group,The heterogeneities were within the acceptable range with statistical significance,The results of OS were invalid due to relatively large heterogeneity,The incidence of headache did not significantly differ between two groups (OR=1.05;95％CI:0.72-1.55;P=0,79).Conclusions Compared with WBRT alone,WBRT combined with TMZ is beneficial to improve the short-term efficacy,whereas the incidence of hematological toxicity and gastrointestinal reaction is higher,The occurrence of headache does not significantly differ between two groups,The benefit of long-term survival remains uncertain.

Objective:To evaluate the left ventricular myocardial strain in patients with light chain cardiac amyloidosis (AL-CA) with normal left ventricular ejection fraction (LVEF) by three-dimensional speckle tracking imaging(3D-STI), and to explore the clinical value of 3D-STI in predicting the prognosis of AL-CA patients with normal LVEF.Methods:A total of 80 patients with AL-CA and LVEF≥50% were retrospectively analyzed in the Xijing Hospital of Air Force Military Medical University from October 2014 to May 2020.According to whether the patients had endpoint events, they were divided into endpoint event group and non-endpoint event group. The clinical data, conventional echocardiographic parameters, 3D-STI related parameters and follow-up results were collected. Cox regression proportional hazards model was used to analyze the survival status of AL-CA patients with univariate and multivariate regression analyses, in order to find the relevant indicators of conventional echocardiography and 3D-STI to predict adverse events.Results:All patients were followed up for 20(7.3, 40.8) months. At the end of follow-up, 25 patients had all-cause deaths. Compared with the non-endpoint group, the endpoint event group had significantly increased left ventricular end diastolic maximum wall thickness (MLVWT), peak early diastolic flow velocity/peak early diastolic velocity at mitral annulus(E/e′) (all P<0.05), and decreased LVEF, left ventricular global longitudinal strain (GLS) and basal segment longitudinal strain (LS) (all P<0.05). Multivariate cox regression analysis after adjusting for age and gender showed that basal segment LS ( HR=0.812, 95% CI=0.675-0.976, P=0.026) was an independent predictor of end-point events in patients with AL-CA. Kaplan-Meier survival curve showed that AL-CA patients with basal segment LS≤13.07% were more likely to have endpoint events. Conclusions:Basal segment LS can be used as a predictor of endpoint events in patients with AL-CA.

Objective:To summarize the clinical features of 8 cases with intramycardial hematoma(IMH) following congenital cardiac surgery in children.Methods:We retrospectly searched 8 patients with intramycardial hematoma after congenital cardiac surgery in Guangzhou Women and Children’s Medical Center from 2008 to 2024.Results:Mean age and mean weight at surgery were(13±15) months and(7.8±3.5)kg respectively. 6 of 8 cases were interventricular septal hematoma. In the other 2 patients, intramycardial hematoma was located in left ventrical free wall. All IMH were postoperatively detected by transthoracic echocardiaography. Two patients were managed with ECMO intraoperatively. Finally, all patients were discharged successfully with good clinical results. Mean time to IMH resolution in six patients was(33.5±4.6) days and mean left ventricular ejection fraction(LVEF) was 0.60±0.09. Another patient was followed up for 3 months and the IMH was not absorbed. One patient was lost to follow-up.Conclusion:IMH is a rare complication after congenital heart disease. The absorption of hematoma is a dynamic process and mean time to IMH resolution is about 1month. In IMH patients with hemodynamic instability, ECMO can be a good treatment to create opportunities for hematoma absorbtion.
