Objective:This study investigates the significance of human papilloma virus (HPV) subtype detection in opportunis-tic screening for cervical cancer in Uygur and Han women. Methods:Flow-through hybridization gene chip and thin-prep cytology test were used to detect HPV in cervical cell samples from 1140 females. A total of 428 patients had undergone cervical biopsies through colposcopy. The diagnostic results of the HPV subtype test for cervical lesions were evaluated on the basis of histology. Results:Total HPV infection rate for the 1140 cervical samples was 30.3%. The most common HPV subtypes were HPV16, HPV58, HPV52, HPV18, and HPV45. HPV52 infection rate was higher in Han women than in Uygur women, with statistically significant differences between the two (χ2=8.737, P=0.003). Among these cervical samples, the single HPV infection rate was 22.4%(255/1140), whereas the multiple HPV infection rate was 6.1% (69/1140). The sensitivity and specificity of the HPV subtype test for cervical lesions were 86.4% and 24.5%, respectively. The positive and negative predictive values were 58.5%and 59.3%. Conclusion:HPV infection subtypes in Ugyur and Han women have unique characteristics. Subtype detection is important in opportunistic screening for cervical cancer.

Objective To evaluate the correlation between the degree of cochlea endolymphatic hydrops(EH) and hearing loss and symptoms in patients with unilateral Meniere's disease. Methods Fifty seven patients with unilateral Meniere's patients were retrospectively quantitatively analyzed, which evaluated the correlation between the cochlea EH and hearing loss and symptoms. The affected ears in the experimental group(57 ears) and the asymptomatic ears in the control group(57 ears), were confirmed by bilateral intratympanic Gd-DTPA injection and 3D real IR MRI scan after 24 h. The maximum length of endolymph space and labyrinth chamber along the modiolus cochleae and their ratio which represented the endolymph space proportion of each turn(R1, the basal turn;R2, the middle turn;R3, the apical turn) were calculated. And the paired t test was used to compare the differences in EH degree between the experimental and control group;Pearson correlation analysis was used to analyze the correlation between the cochlea EH degree and hearing loss and duration of symptoms. Results R1, R1 and R3 of ipsilateral cochlea were higher than normal cochlea(ipsilateral R1:0.354±0.097 vs. normal R1:0.185±0.031, P<0.01;ipsilateral R2:0.445 ± 0.098 vs. normal R2:0.201 ± 0.046, P<0.01;ipsilateral R3:0.467 ± 0.102 vs. normal R3:0.221 ± 0.053, P<0.01). A positive correlation was found between the degree of EH in each turn and high-frequency hearing loss(r=0.275, 0.281, 0.329, respectively;all P<0.05), whereas no correlation was found between the extent of EH and the time of vertigo, tinnitus and hearing loss(P>0.05). In addition, there was a correlation between the degree of EH in the apical turn and low, medium, high-frequency hearing loss(r=0.271, 0.269, 0.329, respectively; all P<0.05). Conclusions The degree of cochlea EH in the basal and second turn showed great relevance with the high-frequency hearing loss, and the apical turn EH degree was relevant with the low, medium, high-frequency hearing loss, but there was no correlation between the EH degree of each turn, ages and symptoms.

Objective:To explore the effect of Shugan Yishen prescription（SGYS） on the tamoxifen （TAM） -resistant cell line LCC9 by the intervention of exosome-mediated crosstalk in the breast cancer microenvironment. Method:Four groups of serum were set up， specifically， a blank group， a TAM （2 mg·kg^-1·d^-1） group，an SGYS（113.2 g·kg^-1·d^-1） group，and a combination group. The exosomes of LCC9 cells were extracted by ultracentrifugation and identified by transmission electron microscopy （TEM），nanoparticle tracking analysis （NTA）， and Western blot. Then the collected LCC9 exosomes （LCC9-EXO） were co-cultured with bone marrow mesenchymal stem cells（BMMSCs），and 10% of the above four groups of serum were added to the co-culture system. After 48 hours of co-culture，the exosomes of BMMSCs （BMMSCs-EXO） were extracted and incubated with LCC9 cells. Fluorescence microscope was used to observe the uptake of exosomes by cells. Cell counting kit-8 （CCK-8） assay，flow cytometry， and Transwell assay were used to detect the effects of drug-containing serum in the four groups on the proliferation，apoptosis， and migration of LCC9 cells. Western blot was used to detect the protein expression of CD24，CD44，human epidermal growth factor 2（HER2）， and estrogen receptor α （ERα） in each group. Result:Fluorescence microscope observed that LCC9-EXO could be taken up by BMMSCs，and BMMSCs-EXO could be taken up by LCC9 cells. CCK-8 assay revealed that compared with the TAM group，the SGYS group and the combination group showed reduced cell proliferation ability at each period （P<0.05），especially the combination group，but no statistically significant difference between the SGYS group and the combination group was observed （P<0.05）. Flow cytometry revealed that compared with the TAM group，the SGYS group and the combination group showed increased levels of apoptosis （P<0.05）. Transwell assay revealed that compared with the TAM group，the SGYS group and the combination group showed decreased cell migration ability （P<0.05）. Western blot revealed that compared with the TAM group，the SGYS group and the combination group showed up-regulated expression of ERα and CD24（P<0.05），and down-regulated expression of HER2 and CD44 （P<0.05）. The effect of the combination group on protein expression was superior to that of the SGYS group （P<0.05）. Conclusion:SGYS reverses the TAM resistance of LCC9 cells by interfering with the crosstalk between BMMSCs-EXO and LCC9-EXO.

OBJECTIVETo investigate the clinical phenotype and genetic characteristics of an azoospermia patient with ring 22 chromosome syndrome.

METHODSWe analyzed the clinical data of an azoospermia patient with ring 22 chromosome syndrome and reviewed relevant literature.

RESULTSThe patient was a short 29-year-old male, with bilateral testes small in size and soft in texture. Seminal examination indicated azoospermia. Chromosome analysis showed the karyotype of the patient to be 46, XY, r (22) (p11, q25). The level of testosterone was low, and the testicular tissue was brittle and easy to break. Pathological microscopy revealed reduced number of Sertoli cells and germ cells in the seminiferous tubules and thinner layers of cells. All the germ cells were spermatogonia. Neither spermatocytes nor sperm cells were found, which suggested complete spermatogenic failure. Mild interstitial fibrosis was visible in part of the seminiferous tubule walls.

CONCLUSIONPatients with ring 22 chromosome syndrome usually represent normal clinical phenotypes. However, this kind of genetic abnormality often induces severe testicular damage and spermatogenic arrest, which may result in azoospermia.

Objective:To describe the epidemiological characteristics of mental disorders in Ximeng Wa Au-tonomous County and explore psychosocial risk factors of mental disorders. Methods:Two thousand three hundred and eighty one residents aged 1 8 years and over were sampled using multistage sampling in Ximeng Wa Autono-mous County in 2013. All respondents were investigated by face-to-face interview. Mental disorders were screened out by using the General Health Questionnaire (GHQ)and diagnosed according to the International Classification of Diseases Checklist (ICD-10-Checklist)criteria. Results:Life time prevalence of any mental disorder was 19. 86%(419/2110). The lifetime prevalence rates of substance use disorder,anxiety disorder,insomnia,mood disorder, schizophrenia were 12. 99%(274/2110),6. 30%(133/2110),2. 94%(62/2110),2. 32%(49/2110)and 1. 00%(21/2110)respectively. Male (OR=0. 43),older age (35 -49 years,OR=1. 78;50 -64 years,OR=2. 59;≥65 years,OR=3. 5 1 ),unmarried and other marital status (OR=0. 3 1 ),non-Wa and non-Lahu ethnic groups (OR=0. 29)were associated with neurotic,stress-related and somatoform disorders. Male (OR=2. 41),older age (35 -49 years,OR=2. 29;50-64 years,OR=3. 20;≥65 years,OR=4. 58),non-farmer and non-self-employed occupation (OR=0. 41),and non-Wa and non-Lahu ethnic groups (OR=0. 32)were associated with psychoactive substance use disorder. Male (OR =0. 35 ) and order age (≥65 years,OR =3. 05 ) were associated with mood disorders. Conclusion:Lifetime prevalence of any mental disorder,substance use disorders and anxiety disorders are high in Ximeng Wa Autonomous County.

Objective To explore the MRI features of acute optic neuritis with positive aquaporin?4 (AQP4) antibodies and myelin oligodendrocyte glycoprotein (MOG) antibodies during the first attack. Methods Eighty five patients (105 affected nerves) with first?episode AQP4?seropositive optic neuritis (AQP4?ON; n=58; 64 affected nerves) and MOG?seropositive optic neuritis (MOG?ON; n=27; 41 affected nerves) diagnosed by our hospital Neuro?ophthalmology Department between April 2014 and December 2017 were retrospectively analyzed. Double seronegative patients or double seropositive patients were not included. All patients underwent orbital conventional MRI; 29 patients also underwent RESOLVE?DWI and 55 underwent brain T2 fluid?attenuated inversion recovery (T2FLAIR). Theclinical features (age, gender, disease duration) and MRI features (T2WI, bilateral involvement, the degree and extent of enhancement, the extent of involvement, the affected segment and ADC values of nerve; demyelinating lesions of brain) were analyzed by 2 doctors. The qualitative parameters were compared with χ2 test or Fisher exact test and the quantitative parameters were compared with two independent sample t test (normal distribution) or the Mann?Whitney U test (skewed distribution). The Kappa test was used to test the consistency of the qualitative characteristics of the images evaluated by the 2 doctors. The interclass correlation coefficient (ICC) was used to test the consistency of the ADC obtained by the 2 doctors. Results There were no significant differences in the distributions of age and disease duration between 2 groups (t=1.911, Z=-1.054, P>0.05). AQP4?ON had a higher female proportion (χ2=13.911, P<0.05) and showed mainly unilateral involvement. MOG?ON more commonly showed bilateral involvement (χ2=17.640, P<0.05), but there were no significant differences in the demyelinating lesions of brain (χ2=0.000)and the presence/absence of optic tract involvement (both P>0.05). There was a higher probability of optic nerve swelling, long segmental lesions and optic nerve head involvement in MOG?ON(χ2=16.845, 13.525, 13.264, P<0.05). Moreover, the rate of obvious enhancement and the involvement of optic chiasm was higher in AQP4?ON(χ2=7.152, 5.088, P<0.05). RESOLVE?DWI showed the ADC values of the AQP4?ON were significantly lower than those of MOG?ON (t=-3.300, P<0.05). The qualitative features of image evaluated by the 2 doctors were consistent well (Kappa=0.712-0.932, P<0.001).The ADC values obtained by the 2 doctors were consistent well (ICC=0.942, P<0.001).Conclusions For the first?episode acute optic neuritis, AQP4?ON hasobvious female predilection and the trend of unilateral involvement and obvious enhancement, while MOG?ON isoften involved bilaterally with longitudinally extensive lesions. The ADC values of the AQP4?ON are significantly lower than those of MOG?ON and AQP4?ON are more vulnerable to involve the optic chiasm. Conventional MRI and RESOLVE?DWI are helpful for differentiating AQP4?ON from MOG?ON during the early stage of the disease course.
