Objectives To study the role of IL-17 and IL-23 in non-Hodgkin lymphoma (NHL) by detecting the expression levels of IL-17 and IL-23 in peripheral blood of B-cell non-Hodgkin lymphoma patients treated by RCHOP.Methods T wenty-five patients with B-cell NHL who achieved remission after 6 to 8 cycles of R-CHOP as a NHL group,20 healthy volunteers were recruited as a normal control group.RT-PCR was used to detect the expression levels of IL-17 mRNA and IL-23mRNA in NHL patients and health volunteers.Results The expression level of IL-17mRNA andIL-23 mRNAin the patients with NHL before therapy and the patients with NHL who achieved remission was lower than that in the normal control group (P＜0.05).The expression level of IL-17mRNA andIL-23mRNA in the patients with NHL who achieved remission was higher than that in the patients with NHL before therapy (P=0.001,P＜0.05).Conclusion IL-17 and IL-23mRNA expressions are higher after treated with R-CHOP.The expression levels of IL-17 mRNA and IL-23 mRNA in NHL patients are related with prognosis and efficacy.

Objective To investigate the pelvic floor in cystocele patients using translabial ultrasound,and discuss the ultrasound appearance.Methods Translabial 2D ultrasound was performed on 136 patients who were diagnosed or suspected as anterior vaginal wall prolapse or cystocele using pelvic organ prolapse quantitation system,the position of bladder,the retrovesical angle and urethral rotation were measured during maximum Valsalva maneuver.Cystocele subtypes were diagnosed according to the ultrasound findings.Results Translabial 2D ultrasound diagnosed 88 cases cystocele based on the position of bladder,retrovesical angle and urethral rotation,including ten cases cystocele type Ⅰ,32 cases type Ⅱ and the remaining 46 classified as type Ⅲ.Conclusions Translabial 2D ultrasound successfully acquired the ultrasonic characteristics of cystocele subtypes,which could provide imaging evidence for clinic diagnosis of this disease.

Objective To evaluate the value of systemic ultrasound examination in prenatal diagnosis of fetus skeletal system anomaly combined with chromosomal abnormalities. Methods In 12 146 patients examined by systemic ultrasound in Sichuan Provincial People's Hospital from 2006 to 2013, 21 fetus with skeletal system abnormalities and chromosomal abnormalities were included in the study. And the correlation between skeletal system abnormalities and chromosomal abnormalities in fetus was evaluated. Results This study involves 21 cases of abnormal fetal skeletal system combined with chromosomal abnormalities. Among them, there were 5 cases of trisomy-21, 11 cases of trisomy-18, 3 cases of trisomy-13, 1 case of [46, XYt (6, 9)], and 1 case of (46, XY, 6 q-). In 19 cases, other system malformations were found, including nervous system abnormalities, facial deformity, cardiac structural abnormalities and intrauterine retardation. In the rest 2 cases, skeletal system abnormalities were the only structural malformation detected on prenatal ultrasound examination. Conclusion Systemic ultrasound can't only detect fetal skeletal system abnormalities but also provide clues for specific chromosomal abnormalities, which was useful in optimizing prenatal diagnosis.

Objective:To explore the correlation between white matter lesions (WML) at different locations and cognitive function.Methods:The cognitive function of 68 patients with WML in Beijing Electric Power Hospital from January 2019 to May 2020 were assessed with Montreal Cognitive Assessment Scale (MoCA), and the extent of WML were assessed with age-related white matter changes rating scale(ARWMCRs). Correlation between the ARWMCRs scores of different locations and the scores of all locations and the scores of cognitive function, as well as the relationship between the ARWMCRs scores of different locations and each subitem of cognitive function were analyzed.Results:In 68 patients with WML, the degree of lesions in different parts from heavy to light was frontal area, parietooccipital area, basal ganglia area and temporal area, and no white matter lesions were found in infratentorial area. Except the basal ganglia region, the ARWMCRs scores in other regions and the total score were negatively correlated with MoCA score, among which, the ARWMCRs score in left frontal area, right frontal area, left parietal pillow and right parietal pillow region had the strongest correlation with MoCA score( rs=- 0.388, - 0.479, -0.418, -0.502, all P<0.01).In WML patients, the left frontal area was negatively correlated with language, abstraction and orientation ( rs=- 0.479, - 0.324, - 0.288, all P<0.01).The ARWMCRs score in right frontal area was negatively correlated with visual spatial and executive function, memory, language, abstraction, and orientation ( rs=- 0.324, -0.272, -0.459, -0.382, -0.352, all P<0.05). The ARWMCRs score in left parietal occipital region was negatively correlated with visual spatial and executive function and memory ( rs =-0.287、- 0.270, all P<0.05). The ARWMCRs score in right parietal occipital region was negatively correlated with memory, language, abstraction and orientation ( rs=-0.366, -0.289, -0.260, - 0.307, all P<0.05).The ARWMCRs score in left temporal region was negatively correlated with language, abstraction and orientation ( rs=- 0.248, -0.372, - 0.608, all P<0.05).The ARWMCRs score in right temporal region was negatively correlated with abstraction and orientation ( rs=- 0.525, -0.465, all P<0.01).The ARWMCRs score in right basal ganglia was negatively correlated with orientation and memory ( rs=- 0.455, - 0.275, all P<0.01), while The ARWMCRs score in left basal ganglia was not correlated with MoCA subitems. Conclusions:The frontal area and parietal occipital area are the most serious lesions in WML patients, and the lesions in these two areas also cause the widest range of cognitive impairment.

Objective To dynamically observe and evaluate the position and movement of anterior pelvic floor organs in vaginal delivery and selective caesarean section primipara with translabial two-dimensional 2D ultrasound and discuss the short-term effect of delivery mode on the anterior compartment of pelvic floor Methods Translabial 2D ultrasound was performed on selective caesarean section and vaginal delivery primipara in 6-8 weeks The position of bladder the existence of bladder neck funneling were observed and the mobility of bladder neck and the urethral rotation angle were measured during maximum Valsalva maneuver Results The mobility of bladder neck was larger in vaginal delivery group than selective caesarean section group during maximum Valsalva maneuver The rates of bladder neck funneling cystocele and stress urinary incontinence were higher in vaginal delivery group Conclusions Translabial 2D ultrasound could dynamically observe and evaluate the position and movement of anterior pelvic floor organ which could be used to assess the effect of delivery mode on anterior compartment of pelvic floor The short-term effect of vaginal delivery on anterior compartment of pelvic floor is greater than that of selective cesarean delivery.

Objective:To observe the effects of orbital bone density on the stress distribution of implant-bone surface.Methods:The 3D finite element analysis craniofacial model with eight HU values(300 -1 0 000)was established.A force of 20 N along the im-plant axis was applied on the model.The stress values and distribution were calculated and analyzed.Results:The peak of stress val-ue and displacement discreased as HU value increased.In the range of HU value 800 -1 000 HU,the peak of stress value and dis-placement of bone interface did not significantly change with the increasing of HU value.Conclusion:Orbital bone density is an im-portant factor on orbital implant failure when HU value below 800.
