Background and purpose:At present, color Doppler ultrasound scoring and radionuclide imaging are two important imaging methods for diagnosing thyroid nodules, but their checking principle is different. Which method is better? Or combining them will be the best method for diagnosing thyroid nodules? This study aimed to compare the value of99mTcO4- combined with99mTc-methoxyisobutylisonitrile (MIBI) imaging, ultrasound scoring method and ultrasound scoring method+99mTcO4-+99mTc-MIBI imaging in diagnosis of thyroid nodules.Methods:The results of ultrasound scoring method and99mTcO4- combined with99mTc-MIBI imaging were compared in 50 patients with 54 thyroid nodules, and then compared with pathological findings. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of the methods were calculated.Results:A total of 54 thyroid nodules were found pathologically including 20 malignant and 34 benign nodules. The sensitivity, specificity, accuracy, PPV and NPV of99mTcO4- combined with99mTc-MIBI imaging were 80.00% (16/20), 70.59% (24/34), 74.07% (40/54), 61.54% (16/26), 85.71% (24/28), re-spectively. Those of ultrasound scoring method were 80.00% (16/20), 88.24% (30/34), 85.16% (46/54), 80.00% (16/20), 88.24% (30/34), respectively. And those of ultrasound scoring method+99mTcO4-+99mTc-MIBI imaging were 100.00% (20/20), 64.71% (22/34), 77.78% (42/54), 62.50% (20/32), 100.00% (22/22), respectively. The sensitivity of ultrasound scoring method+99mTcO4-+99mTc-MIBI imaging was higher than ultrasound scoring method or99mTcO4-+99mTc-MIBI imaging along (100.00%vs 80.00%, 100.00%vs 80.00%,χ2 value was 4.444 4 and 4.444 4,P value was 0.035 0 and 0.035 0, respectively). The specificity of ultrasound scoring method was higher than those of two methods combined together (88.24%vs 64.71%,χ2 value was 5.230 8,P value was 0.022 2). However, no factorial negative thyroid nodule was found by ul-trasound scoring method+99mTcO4-+99mTc-MIBI imaging.Conclusion:Ultrasound scoring method+99mTcO4-+99mTc-MIBI imaging can offer comprehensive diagnosis of thyroid nodules from their structure and function to avoid missed diagnosis.

Objective To investigate the clinical risk factors of delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH).Methods From January 2015 to April 2016,106 consecutive patients with aSAH treated with endovascular embolization at the Department of Neurosurgery,Nanjing General Hospital of Nanjing Military Command were enrolled retrospectively.The patients were divided into either a DCI group (n =34) or a non-DCI group (n =72) according to whether the occurrence of DCI.The general information of patients were collected,including sex,age,Hunt-Hess grade,modified Fisher grade,world federation of neurosurgical societies (WFNS) grade,acute cerebral edema,early (bleeding 1-3 d) hypoalbuminemia,and hypohemoglobinemia.Univariate and multivariate Logistic regression analyses were used to analyze the risk factors for occurrence of DCI.Results The incidence of DCI was 32.1％ (34/106).The Hunt-Hess grade ≥ Ⅲ,modified Fisher grade ≥ Ⅲ,WFNS grade ≥ Ⅳ,acute cerebral edema,the incidences of hypoalbuminemia and hypohemoglobinemia in the DCI group were higher than those in the non-DCI group.There were significant differences between the 2 groups (all P ＜ 0.05).There were no significant differences in the ratios of sex,age ≥ 55 years,hypertension,diabetes and hyponatremia between the 2 groups (all P ＞ 0.05).In univariate analysis,the Hunt-Hess grade ≥ Ⅲ grade,modified Fisher grade ≥ Ⅲ,WFNS grade ≥ Ⅳ on admission,and hypoalbuminemia were used as the independent variables for multivariate analysis,the results showed that WFNS grade ≥ Ⅳ (OR,8.02;95 ％ CI 2.41-26.70),modified Fisher grades ≥ Ⅲ (OR,4.44;95％ CI 1.38-14.32),and hypoalbuminemia at day 1-3 (OR,5.42;95％ CI 1.40-20.76) were the independent risk factors for occurring DCI in patients with aSAH (all P ＜ 0.05),and the Hunt-Hess grade ≥ Ⅲ was not the risk factor for occurring DCI in patients with aSAH (OR,1.86;95％ CI 0.39-8.88,P ＞ 0.05).Conclusion The patients with hypoalbuminemia,WFNS grade≥Ⅳ on adrnission,and modified Fisher grade ≥ Ⅲ may were the independent risk factors DCI after aSAH,and the clinical diagnosis and treatment should attach great importance to.

A 22-year-old male patient visited the Department of Dermatology of the First Affiliated I Iospital of Zbengzhou University on October 31,2016 due to dark red papules,nodules,pustules and cysts on the face,neck,back and in the axillary and inguinal regions for 6 years,and multiple dark purple plaques and ulcers on bilateral lower limbs for 1 year.Six years ago,the patient was diagnosed with acne in other hospital,and no treatment was given.One year ago,multiple purple plaques occurred on the bilateral lower limbs,which then ruptured and progressed into ulcers with diameters of 1-12 cm.On May 9,2002,the patient visited the Department of Pediatric Medicine of the First Affiliated Hospital of Zhengzhou University due to the left knee joint swelling and pain for half a year.Laboratory examination showed negative rheumatoid factor,and smear examination of the left knee joint effusions revealed that there were neutrophils and a small amount of lymphocytes and monocytes in the joint effusions,and no abnormal cells were observed.Then,the patient was diagnosed with pyogenic arthritis of the left knee.Physical examination at admission showed poor general condition,walking difficulty,slightly increased blood pressure of 142/92 mmHg (1 mmHg =0.133 kPa),multiple purple plaques on the bilateral lower limbs with central ulcer formation.Histopathological examination of ulcer margin on the lower limbs showed ulceration,intercellular edema and infiltrating neutrophils in the epidermis,and edema,focal erythrocyte extravasation,diffuse infiltration of neutrophils,lymphocytes and histiocytes in the superficial and middle dermis.Clinical manifestations and pathological features confirmed a diagnosis of pyoderma gangrenosum.There were extensive inflammatory papules,pustules,abscesses and cysts on the face,neck,waist and back,and a small amount of dark red nodules on the axillary and inguinal regions,which were consistent with cystic acne and hidradenitis suppurativa.As PSTPIP1 gene sequencing showed,no mutations were found in exon fragments,while compound heterozygous mutations c.36 + 68 G ＞ A,c.137 + 47 G ＞ C and c.562 + 114 C ＞ G her were found in intron fragments.Among 100 healthy controls,45 carried the same mutations.So,these mutation sites were considered to be polymorphic sites,and the pathogenicity of these mutations was still unclear.Finally,the patient was diagnosed with PAPASH syndrome.The patient was treated with methylprednisolone,cefminox,isotretinoin and thalidomide,and the lesions were markedly improved after 2 weeks.Now the patient was still followed up.

Objective:To systematically evaluate the intervention effect of exposure and response prevention (ERP) on obsessive compulsive disorder (OCD).Methods:PubMed, Web of Science Core Collection, EBSCO, Cochrane Library, Embase, Science Direct, Wanfang Data, China National Knowledge Infrastructure and VIP-CSTJ were used to collect randomized controlled studies related to ERP for OCD.Randomized controlled studies that met the criteria were included, with the score of Yale-Brown obsessive-compulsive scale as the primary outcome indicator and the scores of anxiety and depression scale as secondary outcome indicators, while the included literatures were evaluated for literature quality and data extraction.Review Manager 5.3 and Stata 16.0 softwares were used to conduct Meta-analysis on the extracted data.Results:Twenty-seven studies with a total of 1 239 patients were included, and 599 cases in the ERP group and 640 cases in the control group.Meta-analysis results showed that the efficacy of ERP group was significantly better than that of blank control group(MD=-6.55, 95% CI: -8.75--4.35, P<0.001) and significantly better than chlorpromazine control group treatment (MD=-5.88, 95% CI: -8.20--3.56, P<0.001) for improving patients' obsessive-compulsive symptoms, but not significantly different from CBT intervention (MD=0.21, 95% CI: -1.62-2.04, P=0.82), and the efficacy of ERP and CBT had no significant during the post-intervention follow-up period (MD=0.41, 95% CI: -2.45-3.27, P=0.78). For improving patients' depressed mood, ERP was effective in improving patients' depressed mood (SMD=-0.45, 95% CI: -0.74--0.17, P=0.002), but not significantly different from CBT (SMD=-0.05, 95% CI: -0.27-0.16, P=0.62). For improving anxiety, the efficacy of ERP group was not different from that of control group (SMD=-0.17, 95% CI: -0.56-0.23, P=0.41). Conclusion:ERP has good feasibility in improving obsessive-compulsive symptoms and depression in patients with OCD.However, long-term efficacy was not verified for improving anxiety and maintaining long-term efficacy during the follow-up period.

OBJECTIVE: To assess the application value of mapping allele with resolved carrier status (MaReCs) technique for preimplantation genetic testing (PGT). METHODS: The characteristics of MaReCs for PGT and outcome of patients were retrospectively analyzed. RESULTS: Compared with those who could not use the technique, carriers who have used the MaReCs technique were younger, had significantly higher level of anti-Mullerian hormone, more antral follicles, occytes, mature occytes, biopsied embryos and euploid embryos, and lower risks for de novo chromosomal abnormality (P<0.05). It was necessary for couples with fewer oocytes, mature oocytes and balstocyst to preserve discarded embryos to facilitate the test. Carriers who have used the MaReCs technique had higher clinical pregnancy rate and abortion rate compared with those undergoing routine PGT, albeit no significant difference was found between the two groups (P> 0.05). Carriers undergoing MaReCs test could preferentially select embryos with normal chromosome structures for the transfer. CONCLUSION Application of MaReCs has a prerequisite for having a minimum number of occytes and biopsied embryos and using discarded embryos sometimes. MaReCs is efficient for the detection of carrier status of embryos and attaining higher rate of pregnancy and live birth, which can significantly improve the outcome for couples carrying chromosomal translocations.

Objectives: . Branchio-oto syndrome (BOS) primarily manifests as hearing loss, preauricular pits, and branchial defects. EYA1 is the most common pathogenic gene, and splicing mutations account for a substantial proportion of cases. However, few studies have addressed the structural changes in the protein caused by splicing mutations and potential pathogenic factors, and several studies have shown that middle-ear surgery has limited effectiveness in improving hearing in these patients. BOS has also been relatively infrequently reported in the Chinese population. This study explored the genetic etiology in the family of a proband with BOS and provided clinical treatment to improve the patient’s hearing. Methods: . We collected detailed clinical features and peripheral blood samples from the patients and unaffected individuals within the family. Pathogenic mutations were identified by whole-exome sequencing and cosegregation analysis and classified according to the American College of Medical Genetics and Genomics guidelines. Alternative splicing was verified through a minigene assay. The predicted three-dimensional protein structure and biochemical experiments were used to investigate the pathogenicity of the mutation. The proband underwent middle-ear surgery and was followed up at 1 month and 6 months postoperatively to monitor auditory improvement. Results: . A novel heterozygous EYA1 splicing variant (c.1050+4 A>C) was identified and classified as pathogenic (PVS1(RNA), PM2, PP1). Skipping of exon 11 of the EYA1 pre-mRNA was confirmed using a minigene assay. This mutation may impair EYA1-SIX1 interactions, as shown by an immunoprecipitation assay. The EYA1-Mut protein exhibited cellular mislocalization and decreased protein expression in cytological experiments. Middle-ear surgery significantly improved hearing loss caused by bone-conduction abnormalities in the proband. Conclusion . We reported a novel splicing variant of EYA1 in a Chinese family with BOS and revealed the potential molecular pathogenic mechanism. The significant hearing improvement observed in the proband after middle-ear surgery provides a reference for auditory rehabilitation in similar patients.

ObjectiveTo explore the influencing factors of willingness to quit smoking in smokers， and to provide reference for further smoking cessation intervention. MethodsThrough purposive sampling， smokers were recruited from 4 residential communities and 3 companies in Shanghai for an online questionnaire survey. The survey included general demographic characteristics， willingness to quit smoking， smoking condition， tobacco addiction， awareness of influence of smoking， smoking abstinence self-efficacy， and smoking rationalization belief. T-test， χ² test and multiple logistic regression were used to analyze the data. ResultsA total of 336 valid questionnaires were collected. The average age of the smokers was （37.1±10.2） years， and most of their education level was college or above （58.3%）. The daily number of cigarette use was （11.46±7.22） and most of smokers were classified as low nicotine dependence （58.3%）. Today 248 smokers planned to quit smoking in the next six months. Compared with smokers with low smoking abstinence self-efficacy， smokers with high self-efficacy were more likely to quit smoking （OR=2.406，95%CI： 1.357‒4.267）； Smokers with low smoking rationalization belief were more likely to quit smoking than those with high rationalization belief （OR=2.112， 95%CI： 1.167‒3.821）. ConclusionSmoking abstinence self-efficacy has a positive impact on willingness to quit smoking， while smoking rationalization belief has a negative impact on the willingness to quit smoking. Efforts to improve smoking abstinence self-efficacy and dispel smoking rationalization beliefs of smokers should be made to promote the intention to quit among smokers.
