Objective To investigate the indications,approaches,and essentials of cranio-orbital surgeries for orbital apextumors.Methods The clinical data of 48 patients with orbital apextumors treated by refined transcranial orbitotomy through superolateral approach were analyzed retrospectively,34 tumors were excised with orbitoptenonal approach,while 14 tumors were excised with orbltotrontal approach,orbitozygomatic approach,or zygomatic-ptefional approach.Results Of the 48 orbital apextumors,33 cases were totally resected,7 cases were subtotally resected,and 6 cases were partly resected.The other 2 cases were taken biopsies.The optic functions improved or retained in 40 cases,7 cases suffered from eye-moving disfunction or visual-acuity declines,and 1 case suffered from hemiparalysis.Conclusions Tumors in the posterior and apex part of the orbit,or tumors extended from the orbit to the cranial,can be well treated through transcranial approach.Appropriate methods may help to bring maximum convenience to exposure and excision of the lesion,and to conserve the functions.Unnecessary injuries could be avoided as well.

Objective To investigate the aassociation of a microRNA-137 (miR-137) polymorphism, single nucleotide polymorphism (SNP) rs1625579, with neurocognitive function in patients with schizophrenia. Methods A total of 250 patients with schizophrenia were included in this study. The positive and negative syndrome scale (PANSS) was used to evaluate patients. The brief assessment of cognition in schizophrenia (BACS) scale was used to determine neurocongnitive functions in patients. Blood samples of patients were collected, and SNaPshot technique was used to compare the neurocognitive functions of different genotypes of rs1625579. Results The genotypes of TT, GT and GG were 221 (88.4%), 28 (11.2%) and 1(0.4%). There was no significant difference in PANSS score between TT genotype carriers and G allele (GG+GT) carriers. The detection of BACS showed that the digit sequencing score was significantly lower in patients with TT genotype than that of G allele (GG+GT) carrier ( P<0.05). There were no significant differences in other scores of BACS evaluation between two groups of patients. Conclusion The miR-137 polymorphism influences the working memory performance of schizophrenic patients in Chinese Han population.

Objective To evaluate the effect of post-dilatation on in-stent restenosis of long lesion coronary heart disease patients received percutaneous coronary artery interventional(PCI) therapy.Methods A total of 92 cases coronary heart disease patients in Gaoxin Hospital of Xi'an from January 2008 to January 2014 were randomly divided into the post-dilatation deployment group (n =47) and control group (n =45).The postdilatation deployment group were given stent after expansion after conventional coronary stenting, while the control didn't use after expansion.The clinical features and profile of drug-eluting stent(DES) implantation and stent restenosis(examined by 256-shce spiral computed tomography coronary angiography(MSCTCA) and major adverse cardiac events(MACE) within hospitalization and 12 months were observed.Results Stent restenosis occurred in 1 patient(2.1％) in the post-dilatatioh deployment group and 8 patients(17.7％) in the control group in 12 months examed by MSCTCA,the difference was significant(P=0.03).MACE occurred in 3 patients (6.4％) in the post-dilatation deployment group and 11 patients (24.4％) in the control group, the difference was significant (P =0.03).Conclusion Routine post-dilatation tactics is effective for long lesion coronary heart disease patients with PCI.It is associated with lower coronary restenosis and lower MACE.

Objective To evaluate the application value with Energy Spectrum CT multi -parameter quanti-tative value in differentiating pulmonary occupying lesions (>0.5cm in diameter).Methods Those were retrospec-tively analyzed on 58 cases in pulmonary occupying lesions performed spectrum dual -phase enhanced CT scan and confirmed by pathology,including malignant group 48 cases;10 cases of benign group.Iodine content(IC)was meas-ured in arterial phase(AP)and venous phase (VP)in iodine based on the image and the level of the aorta,and nor-malized iodine concentrations were calculated in the two phases lesions compared with aorta,and the difference between the two normalized iodine concentrations ICD (ICD =NICvp -NICap).To measure the CT value of lesions on 50keV and 100keV energy image,and calculate the energy attenuation curve slope,namely |Hu (100 kev -50kev)/Hu50 |.The differences of NIC,curve slope,and ICD were compared between benign and malignant pulmonary occupying lesions using independent sample t test method.Results In two phase scan,NIC,curve slope of the venous phase and ICD in malignant group were significantly higher than the benign group,(NIC,curve slope of the venous phase and ICD of the malignant group:NICap:0.180 ±0.051,NICvp:0.463 ±0.086,1.696 ±0.475,ICD:0.284 ± 0.071;NIC,curve slope of the venous phase and ICD of the benign group:NICap:0.123 ±0.062,NICvp:0.290 ± 0.119,1.169 ±0.582,ICD:0.166 ±0.073,),but there was no significant difference between the patients with benign and malignant lesions in curve slope of the arterial phase.Conclusion Energy spectrum CT dual -phase enhanced scan can differentiate the nature of benign and malignant pulmonary occupying lesions,and has certain clinical application value.

Objective To study the clinical value of whole －body magnetic resonance diffusion weighted imaging(WB－DWI) in evaluating the chemotherapy response for lung cancer,thus to provide evidence for optimizing clinical imaging examination. Methods From October 2017 to May 2018,60 patients with lung cancer confirmed by histopathology in Linfen Central Hospital were selected. The patients underwent DWI examinations before chemotherapy and after two cycles of chemotherapy. The change of tumor size,distant metastasis and apparent diffusion coefficient (ADC) value were compared before and after chemotherapy. The correlation between the change rate of ADC value and the shrinkage rate of tumor size in the effective group was analyzed. Results Of 60 cases,1 case had new cerebral metastases after chemotherapy. There were statistically significant differences in ADC value [(1. 12 ± 0.33) ×10 －3mm2/svs.(1.56±0.40) ×10 －3mm2/s]andtumorsize[(4.63±2.75)cmvs.(2.28±1.45)cm] between before and after chemotherapy in the effective group(t= －3. 954,4. 711,all P＜0. 01). There was correlation between the change of ADC value and tumor size(r=0. 34,P＜0. 05). Conclusion WB－DWI can not only detect the change of tumor size and distant metastasis quickly and effectively,but also can observe the microscopic changes of tumor cells by measuring ADC value. So it can predict the early therapeutic response of the tumor and make effective evaluation for the staging and chemotherapy response of lung cancer.

Objective To evaluate the application value of whole exome sequencing (WES) in diagnosis of NDDs (neuro-developmental disorders) children.Metheod WES was used for the diagnosis of 35 unexplained NDD children, which admitted to the outpatient and ward of Children′s hospital affiliated to Capital institute of pediatric from November 2015 to November 2016.These children′s clinical data was collected detailedly.Using bioinformatics software tools combining with patient′s phenotype, the candidate genetic/genomic variants of these patients were identified from WES data.The final pathogenicity of genetic/genomic variants was interpreted according to the guideline of the American College of Medical Genetics and Genomics (ACMG), meanwhile, the variants validation and co-separation analysis in the parents and their family members were performed by Sanger sequencing, real time-PCR and multiplex ligation-dependent probe amplification (MLPA).Results 14 pathogenic single nucleotide variants (SNVs) and three pathogenic copy number variations (CNVs) were detected in the 35 NDD children, the detection rate in this study is 48.6%.Among the 14 pathogenic SNVs, 11 of them are the definite NDD-related genes according to OMIM database (such as CHARGE syndrome, Wiedemann-Steiner syndrome, Cockayne syndrome, etc.), and six of them are de novo (6/11, 54.6%).Three pathogenic CNVs were identified from WES data, including two microduplications and one microdeletion.Meanwhile, a female child carrying a frame shift mutation in MECP2 was found and the germline mosaicism with low-frequency mutation of this site (8.4%) was confirmed by his father's sperm.Conclusions The diagnosis rate of WES in NDDs children is 48.6% in our small-sample study.In addition to pathogenic/likely pathogenic SNVs, CNVs can be detected successfully from WES data, which effectively improved the diagnosis yield in NDDs children.

Objective To investigate the influence of moderate to severe leukoaraiosis (LA) in prognoses of acute ischemic stroke patients after endovascular treatment.Methods From January 2017 to December 2018, 60 patients with acute ischemic stroke due to anterior circulation large vessel occlusion underwent endovascular treatment and obtained complete vessel recanalization in our hospital were evaluated for degrees of LA severity according to head CT scan and van Swieten scale (2-4 scores were defined as moderate-severe LA). According to modified Rankin scale (mRS) scores 90 d after treatment, the patients were divided into poor prognosis group and good prognosis group. Univariate analysis was used to compare the differences of influencing factors of the two groups. Multivariate Logistic regression analysis was further used to explore the influence of moderate to moderate-severe LA in poor prognosis of patients after endovascular treatment.Results Of the 60 patients, 18 did not have LA, 19 had mild LA, and 23 had moderate-severe LA; 32 had poor prognosis and 28 had good prognosis. Univariate analysis showed that the patients from the poor prognosis group had significantly higher proportion of moderate-severe LA (59. 4％ [19/32]vs. 14.3％ [4/28]), significantly higher baseline National Institutes of Health Stroke Scale (NIHSS) scores ([23.4±10.1]vs. [14.7±7.0]), significantly higher baseline diastolic blood pressure ([87.5±18.9] mmHgvs. [78.3±15.1] mmHg), significantly higherproportion of patients with hypertension history (68.8％ [22/32]vs. 42.9％ [12/28]), and statistically older age ([70.6±9.4] yearsvs. [61.3±12.5] years) than the patients from the good prognosis group (P<0.05). On multivariable Logistic regression analysis, the presence of moderate-severe LA (OR=5.032, 95％CI: 1.026-24.679,P=0.046) and baseline NIHSS scores were independent risk factors for poor prognosis of patients after endovascular treatment.Conclusion Patients with acute ischemic stroke accompanied with moderate-severe LA are more likely to have poor prognosis after endovascular treatment.

Objective:To explore the correlations of moderate to severe leukoaraiosis (LA) with hemorrhagic transformation (HT) and prognoses of patients with acute ischemic stroke after intravenous thrombolysis.Methods:Clinical data of 144 patients with acute ischemic stroke who underwent intravenous thrombolysis in our hospital from August 2017 to November 2018 were retrospectively collected. Van Swieten scale (vSS) was used to determine the leukoaraiosis degrees in these patients based on CT findings of the head before treatment. According to the CT results of head re-examination within 24 h of treatment, HT appearance of the patients was judged. The prognoses of these patients were evaluated according to modified Rankin scale (mRS) scores 90 d after discharge. Multivariate Logistic regression analysis was performed to determine the independent risk factors for HT and prognoses of patients with acute ischemic stroke after intravenous thrombolysis.Results:Among 144 patients, 23 patients (15.97%) had HT and 121 (84.03%) had non-HT; 61 patients (42.36%) were with poor prognosis and 83 (57.64%) were with good prognosis. As compared with patients in the non-HT group, patients in the HT group had significantly higher proportion of patients with moderate to severe LA, D-dimer level and urine specific gravity ( P<0.05). Multivariate Logistic regression analysis showed that moderate to severe LA ( OR=0.281, 95%CI: 0.105-0.753, P=0.012) and D-dimer ( OR=1.654, 95%CI: 1.100-2.489, P=0.016) were independent risk factors for HT. As compared with the patients in the good prognosis group, the patients in the poor prognosis group had significantly advanced age, statistically higher baseline NIHSS scores and proportion of patients with HT and positive urine sugar, significantly higher levels of random blood glucose and D-dimer, significantly higher plasma fibrinogen content, significantly higher international normalized ratio, and significantly longer plasma prothrombin time before treatment ( P<0.05). The TOAST etiological types of patients between good prognosis group and poor prognosis group were significantly different ( P<0.05). Multivariate Logistic regression analysis showed that baseline NIHSS scores ( OR=1.395, 95%CI: 1.213-1.605, P=0.000) and white blood cell count ( OR=1.292, 95%CI: 1.040-1.606, P=0.021) were independent risk factors for poor prognosis. Conclusions:Acute ischemic stroke patients with moderate to severe LA and high D-dimer are prone to HT after intravenous thrombolysis. Acute ischemic stroke patients with higher baseline NIHSS scores and peripheral white blood cell count are prone to have poor prognosis.

Objective:To explore the experience and learning curve of single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach.Methods:Clinical data of 138 patients undergoing single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via oral vestibular approach from Sep. 2019 to Dec. 2021 in the Department of Thyroid and Breast Surgery of Affiliated Hospital of North Sichuan Medical College were retrospectively analyzed. The cumulative sum (CUSUM) method and best-fit curve analysis were used to compare the differences in each index such as operative time, intraoperative bleeding, number of lymph nodes cleared in the central region and postoperative related complications at various stages of the learning curve.Results:All 138 patients underwent single-line suspension rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach, and one patient was converted to open surgery due to large intraoperative bleeding in the mass. There were 14 males and 124 females, mean age (36.07±8.49) years (20-55 years), thyroid tumor size (7.74±6.49) mm (2.4-50mm), 5 cases underwent Subtotal thyroidectomy, 129 cases underwent Unilateral lobectomy + lymph node dissection in the middle region, and 4 cases total thyroidectomy + central zone lymph node dissection. The number of surgical cases corresponding to the apex of the CUSUM learning curve was 45, and the learning curve was divided into two stages: the learning improvement stage (1-45 cases) and the mastery stage (46-138 cases). The operative time, intraoperative bleeding, postoperative hospital stay, and chin numbness were all lower in the proficiency period than in the learning and training period ( P<0.05), and the number of lymph nodes cleared in the central region was larger than that in the learning and improvement stage ( P<0.05), while the differences in other indexes between the two stages were not statistically significant ( P>0.05) . Conclusion:The single-line suspension suction rod-assisted hybrid cavity-building thyroid surgery via the oral vestibular approach has clinical application value and is worth promoting, and the number of surgical cases to be accumulated to master this technique is 45.
