Objective To investigate functional connectivity between the two hemispheres in patients with positive symptoms of schizophrenia using voxel-mirrored homotopic connectivity ( VMHC ) based on resting-state functional magnetic resonance imaging (rs-fMRI). Methods Eighteen patients with positive symptoms of schizophrenia and 22 healthy controls underwent the rs-fMRI. The whole brain VMHC was calculated in order to provide imaging basis for the study of the pathological mechanism of schizophrenia. Results Compared to the controls, VMHC values were decreased in the bilateral orbitofrontal cortex (t=-5.31, P<0.01), fusiform gyrus (t=-5.16, P<0.01), middle occipital gyrus (t=-5.31, P<0.01) in patients with positive symptoms of schizophrenia. Conclusion The functional coordination between homotopic brain regions is impaired in patients with positive symptoms of schizophrenia .

Objective To evaluate the role of 3.0 Tesla magnetic resonance hysterosalpingography (MR?HSG) work?up in the diagnosis of female infertility. Methods Between July 2015 and December 2018, a total of 1 052 infertile women aged from 20 to 40 years in the Affiliated Hospital of Nanjing University of Chinese Medicine were prospectively enrolled in the study. All the patients underwent pelvic plain scanning and X?ray hysterosalpingography (HSG) followed by MR?HSG examination, and the patency of the fallopian tubes as well as the abnormalities of the uterus and ovaries were evaluated. Among which 33 cases were randomly selected. The chi?square test and Kappa test were used to compare the difference and the consistency of the two methods in the evaluation of fallopian tubes. Results MR?HSG and HSG had good consistency in evaluating tubal patency (Kappa=0.88, P<0.01), and there was no statistically significant difference between the two groups (P=0.65). The examination of MR?HSG was successfully completed in 97.1%(1 021/1 052) cases. There were 81.7% (834/1 021) cases had at least one abnormality. Bilateral tubal, uterine and ovarian abnormalitiesoccurred in 42.6% (435/1 021), 34.2% (349/1 021)and 46.8% (478/1 021) cases, respectively. In which tubal abnormalities display the results as follows: bilateral obstructed 4.7% (48/1 021), bilateral poor pass 8.5% (87/1 021), one smooth one obstructed11.7% (119/1 021), one smooth one poor pass 12.6% (129/1 021), and one poor pass one obstructed 5.1% (52/1 021). Conclusion 3.0 T MR?HSG is expected to be a routineexam for evaluating female infertility, which allows a comprehensive assessment of tubal patency and other pelvic abnormalities of infertile women.

Objective To investigate the status of mental health and related factors in cervical cancer patients received radiotherapy and chemotherapy,and to implement individualized nursing intervention.Methods 60 cervical cancer patients with radiation and chemotherapy were enrolled in this study.The depression self rating scale(SDS),anxiety self-assessment scale(SAS) were evaluated,and the influence factors of self-designed questionnaires were investigated.During the same period,60 healthy women of 4 regions in Shantou were selected as control group.The SDS and SAS were compared in two groups.And combined with the influencing factors of the investigation group after the implementation of nursing intervention 7 d psychological assessment again.Results Cervical cancer patients with radiotherapy and chemotherapy,the SDS and SAS scores were (56.1±7.7)points,(45.2±7.5)points,which were significantly higher than those of healthy women [(45.0±6.3)points,(39.2±6.5)points,t=8.142,4.588,all P<0.01].After 7 days of nursing intervention,the SDS and SAS scores in cervical cancer patients decreased significantly[SDS(49.5±6.8)points,SAS(42.7±6.2)points,P<0.05],and the influence factors of patients' mental health were worry about the hospitalization expenses,do not understand the disease related knowledge,fear,the influence of family and society,and worry about the side effects of treatment on the prognosis of disease(88%,80%,80%,75%,68.3%,65%).Conclusion Cervical cancer patients received radiotherapy and chemotherapy have poor mental health status,in the treatment of diseases at the same time,the nursing staff should give psychological counseling and support,improve the patients' anxiety and depression,promote rehabilitation.
