Objective:To seek specific response points on the body surface of patients with primary dysmenorrhea(PD)by observing blood perfusion unit(PU)at different points of the three Yin meridians of foot using laser speckle contrast imaging(LSCI). Methods:Eighty PD patients were recruited as a PD group,and 80 healthy female undergraduates were taken as a normal group.During one menstrual cycle(before menstruation,during menstruation,and 3 d after menstruation),each participant was examined using the LSCI system to determine PU at bilateral Taixi(KI3),Taibai(SP3),Taichong(LR3),Shuiquan(KI5),Diji(SP8),Zhongdu(LR6),Sanyinjiao(SP6),and Xuehai(SP10)and non-acupuncture points.The researchers in charge of point location,operation,and statistical analysis were not aware of grouping.PU at the detection spots was taken as the outcome measure. Results:Compared with the normal group,the PD group showed increases in PU at right Taixi(KI3)before menstruation(P<0.05)and at bilateral Zhongdu(LR6)and right Diji(SP8)during menstruation(P<0.05).At the other time points,significance was not found between the two groups in comparing PU at the detected spots. Conclusion:Compared with healthy participants,PD patients present specific changes in PU at Taixi(KI3),Diji(SP8),and Zhongdu(LR6)at specific time points during the menstrual cycle,which provides a reference for acupuncture-moxibustion treatment of PD in clinical settings.

Objective:To analyze the epidemiological and clinical characteristics of children with brucellosis, and to provide a practical basis and experience for clinical diagnosis and treatment of brucellosis.Methods:Retrospective analysis was used to collect clinical data of children with brucellosis diagnosed at the Children's Hospital Affiliated to Zhengzhou University from May 2015 to October 2017, and their epidemiological characteristics, clinical manifestations, laboratory tests, and clinical diagnosis and treatment were summarized.Results:A total of 24 children were included, including 14 males and 10 females, with an average age of 6 years (1 year 2 months to 12 years old). Except February, onset throughout the year, higher incidence was from May to July (14 cases, 58.33%). The exposure history of the children was mainly exposure to cattle and sheep and consumption of beef and mutton (18 cases, 75.00%). The main clinical manifestations were fever in 24 cases (100.00%), bone and joint pain in 14 cases (58.33%), hepatomegaly in 9 cases (37.50%), splenomegaly in 7 cases (29.17%). Tube agglutination test (SAT) was positive in 21 cases (87.50%), weakly positive in 1 case (4.17%) and negative in 2 cases (8.33%). Brucella was detected in all 24 cases by microbial culture, and in 18 cases (75.00%) by blood culture. Eighteen cases (75.00%) had liver dysfunction. Thirteen cases were misdiagnosed, and the misdiagnosis rate was as high as 54.17%. Twenty-two cases had been cured after treatment, 2 cases relapsed and recovered after continued treatment. Conclusions:Children with brucellosis have diverse epidemiology and clinical features, and are easily misdiagnosed. For children with fever, bone and joint pain and exposure history, pediatricians should be alert to the possibility of brucellosis, conduct microbiological and serological tests, in order to timely, accurate and standardized diagnosis and treatment of children with brucellosis.

T test was used for variance homogeneity, and t′test was used for variance discrepancy, and P<0.05 was statistically significant. Results The average values of CBF and CBV of the ipsilateral and contralateral cerebral cortex were increased than those of ipsilateral and contralateral cerebral deep white matter respectively(P<0.01). MTT, TTP and TTD of the ipsilateral and contralateral cerebral cortex were decreased than that of ipsilateral and contralateral cerebral deep white matter (P<0.01); CBF of ipsilateral cerebral cortex and CBV of ipsilateral cerebral deep white matter were not different from those of the contralateral cerebral cortex and deep white matter respectively, but CBF of ipsilateral cerebral deep white matter is decreased than that of the contralateral deep white matter (P<0.01). CBV of ipsilateral cerebral cortex is increased than that of the contralateral cerebral cortex (P<0.01). MTT, TTP and TTD of ipsilateral cerebral cortex and deep white matter were increased than those of contralateral cerebral cortex and deep white matter respectively(P<0.01). Conclusion Deep cerebral white matter perfusion decreased more significantly than cortical gray matter in the supply region of chronic cerebral artery severe stenosis or occlusion. CT perfusion imaging can quantify the degree of chronic cerebral ischemia and can provide quantitative diagnostic information for clinical treatment and efficacy evaluation.
