Purpose: This study attempted to detect the changes of cervical cancer screening rate and willingness among female migrants, and the associated socio-demographic factors in Shenzhen city. Materials and Methods: Two citywide surveys were conducted using a multistage random cluster sampling method in 2011 and 2014, respectively. Data on demographic characteristics, screening participation, and willingness to screen were collected. Logistic regression models were applied to detect possible associated socio-demographic characteristics, and their variations with survey years. Results: In total, 12,017 female migrants were enrolled, with a mean age (standard deviation) of 36.73 (6.55) years. From 2011 to 2014, the screening rate increased (25.8% vs. 35.1%, p < 0.001), while the willingness to screen remained stable (82.2% vs. 82.8%, p=0.46). Overall, socio-demographic characteristics of female migrants, including age, marital status, education, monthly income, employment, and medical insurance, were found to be positively associated with screening participation. Similar impacts in relation to willingness were observed except for age. However, these associations varied with survey years, mainly in the contributions of education and monthly income to screening participation, as well as age, monthly income, and medical insurance to willingness of being screened. Conclusion Identifying changes of associated socio-demographic factors precisely is warranted of necessity, which provides novel clues to adjust targeted actions regularly in promoting cervical cancer screening participation among female migrants in Shenzhen.

Objective:To investigate the expression of SET-NUP214 fusion gene in hematological malignancies and to analyze its related clinical biological characteristics.Methods:The clinical data of 24 patients with SET-NUP214 fusion gene-positive hematological malignancies were retrospectively analyzed, and the Kaplan-Meier method was used for survival analysis.Results:Among the 24 patients with SET-NUP214 fusion gene, 15 cases of acute lymphoblastic leukemia (ALL) (13 cases of T-ALL and 2 cases of B-ALL) , 7 cases of acute myeloid leukemia (AML) , and 2 cases of T/myeloid mixed acute leukemia have been identified. The immunophenotype of 13 cases of T-ALL was mainly characterized by CD3 +CD2 -, 73.3% of ALL was characterized by myeloid marker expression, and 85.7% of AML was characterized by CD7 expression. Complete remission (CR) was achieved in 22 patients (91.7%) after induction chemotherapy. All 24 patients received allogeneic hematopoietic stem cell transplantation (HSCT) . With a median follow-up of 24 months, the 3-year relapse free survival (RFS) of AML and ALL was 85.7% and 33.3%, respectively ( P=0.128) . Comparing 13 cases of SET-NUP214-positive and 62 cases of SET-NUP214-negative T-ALL, the CR rates of induction chemotherapy were 92.3% and 93.5% ( P=0.445) , and the 4-week CR rates of induction chemotherapy were 69.2% and 72.6%, respectively ( P=0.187) ; the differences were not statistically significant. After HSCT, the 3-year RFS of SET-NUP214 +T-ALL and SET-NUP214 -T-ALL was 38.5% and 66.4%, respectively ( P=0.028) , and the difference was statistically significant. Conclusion:The SET-NUP214 fusion gene is mainly detected in T cell-derived hematological malignancies, and the prognosis of SET-NUP214 positive T-ALL is relatively poor.

Objective: To observe changes in the molecular expression of the NLR Family Pyrin Domain Containing Protein 3 (NLRP3) pathway in depressed rats after treatment with Xiaoyaosan, and identify the regu-latory mechanism of this compound. Methods: Male Sprague-Dawley rats were randomly divided into five groups with 12 rats in each group, including the control group, model group, Fluoxetine group, Xiaoyaosan group, and MCC950 group. A depression model was generated by chronic immobilization stress (induced by 3 h of restraint immo-bilization every day), and the drugs were administered at the same time in each group for 21 days. The effects of Xiaoyaosan on behavioral changes of depressed rats were observed through macroscopic characterization, body mass, open field experiments, and a sucrose preference test. The mRNA and protein expression of the NLRP3 signaling pathway was examined by fluorescence real-time quantitative PCR and Western blot assays. Results: The Xiaoyaosan group, Fluoxetine group, and MCC950 group rats showed improved depressive behavior and an increased weight of sucrose water consumption. The protein and mRNA expression levels of NLRP3, Caspase-1, and IL-1β were also decreased in the Fluoxetine, Xiaoyaosan, and MCC950 groups. Conclusion: NLRP3, Caspase-1, and IL-1β protein and mRNA expression levels were increased in the cortex of depressed rats, while Xiaoyaosan protected cortical tissue in these rats by decreasing NLRP3, Caspase-1, and IL-1βprotein and mRNA expression.

Purpose: A cross-sectional survey was conducted to evaluate the differences on awareness and attitude towards human papillomavirus (HPV) and its vaccine between local and migrant residents who participated in cervical cancer screening in Shenzhen, China. Materials and Methods: A total of 9,855 females sampled from healthcare institutions in 20 street blocks through the Cervical Cancer Prevention Network were surveyed in this study by a self-administered questionnaire. Multivariate logistic regression was conducted to explore the role of the hukou and resident status in the willingness to receive HPV vaccination. Results: Local residents had a relatively higher awareness of HPV (62.0% vs. 35.6% vs. 29.9%, p < 0.001) and its vaccine (35.3% vs. 15.4% vs. 14.8%, p < 0.001), as well as a higher willingness to receive HPV vaccination (68.5% vs. 62.5% vs. 56.2%, p < 0.001) than non-permanent residents and floating population. Except for age, education level, marital status, monthly income, having daughter(s), and heard of HPV and its vaccine, the hukou and resident status significantly associated with the willingness to receive HPV vaccination (local residents vs. floating population: odds ratio, 1.216; 95% confidence interval, 1.057 to 1.398). None significant difference on the associated factors was found between local residents and internal migrants (p for interactions > 0.05). Conclusion Inequalities in awareness and attitude towards HPV and its vaccine existed between local and migrant residents in Shenzhen. The hukou and resident status did impact on the willingness to receive HPV vaccination, therefore, it is critical to implement effective health education campaigns on HPV and its vaccine among internal migrants.

Objective: To analyze the distribution and associated factors of high-risk genotypes of HPV in cervical infection among women in Shenzhen. Methods: The information on sociodemographic characteristics and HPV genotypes of HPV-positive women who participated cervical screening test from January 2014 to December 2016 was downloaded from Shenzhen Maternity and Child Healthcare Management Information System. According to the pathogenicity, the high-risk HPV genotypes were divided into 15 types including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 and 68; and there were 6 low-risk genotypes including HPV 6, 11, 42, 43, 44, and 81. Chi-square tests were applied to compare the proportions of high-risk HPV infection among women who had different sociodemographic characteristics. A non-conditional logistic regression model was used to analyze the associated factors for high-risk HPV infection. Results: In total, all HIV positives received HPV genotyping, with an average age of (38.08±9.38) years old. There were 9 979 (93.9%) high-risk and 645 (6.1%) low-risk HPV infections. The proportions of HPV infections for high-risk type in each year were 91.5%, 93.8%, and 95.6%, increasing with the screening years (χ²=54.79, P<0.001). Multivariate logistic regression analysis showed that compared with women younger than 25 years old, women in other age groups (at age 26 to 30 years, 31 to 35 years, 36 to 40 years, 41 to 45 years, and 50 years or older) had increased risks of high-risk HPV infection, with OR (95%CI) of 1.67 (1.20-2.31), 1.49 (1.09-2.03), 1.71 (1.23-2.37), 1.65 (1.19-2.31), and 1.84 (1.26-2.67), respectively; compared with the married, single women had a decreased risk of high-risk HPV infection (OR (95%CI): 0.71 (0.50-1.00)); women received HPV testing in 2015 and 2016 showed higher risk of high-risk HPV infection than those in 2014 (OR (95%CI): 1.43 (1.17-1.74) and 2.03 (1.68-2.46)). The 5 most common HPV genotypes were HPV52 (25.1%, 2 670 cases), followed by HPV16 (19.2%, 2 041 cases), HPV58 (13.3%, 1 413 cases), HPV18 (9.9%, 1 048 cases), and HPV51 (9.3%, 993 cases). Conclusion Age, marital status, and screening year were associated with high-risk HPV infections. Besides HPV16 and HPV18, the prevention and control on HPV infections for HPV52, HPV58, and HPV51 should be prioritized in Shenzhen area.

Objective: To discuss the application of matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) in the identification of Aspergillus and evaluate its performance. Methods: the clinical isolates of Aspergillus collected from May 2017 to March 2018 in PLA General Hospital were identified by VITEK MS V3.0 and the results were analyzed. The ITS sequencing resultswere used as the gold standard. Results: It identified 9 Aspergillus species (including 12 Aspergillus species in total) through the V3.0 database, accounting for 86.24% of the total clinical isolates. The identification rate by VITEK MS was 91.49% with 16.51% was not identified. The coincidence rate of genus was 93.62%, of which only two Aspergillus versicolor were identified to the level of the genus. According to the confidence level analysis, 88.30% of the strains obtained more than 99% of the identification rate. 13.83% of the strains did not have the identification results for the first time, with the error rate of 3.19%. After secondary extractions, the percentage of unidentified strain was reduced to 6.38%, and the identification error rate was reduced to 2.13%. Combined with traditional identification and VITEK MS identification, the correct rate of strains identification was 98.94% on genus level, and was 93.62% on species level. The influence of other fungi on Aspergillus identification was 0%. Conclusion As a powerful supplement to the traditional identification method, MALDI-TOF MS showed a lot of convenience when applied in the identification of Aspergillus, which improves the identification accuracy and the identification ability for fungi in laboratory.(Chin J Lab Med, 2018, 41: 577-582)

Objective: To analyze the epidemiological genotype features of human papillomavirus (HPV) in cervical infection and their risks for cervical precancers among women in Shenzhen area. Methods: A total of 2 717 individuals ranging in age from 30~59 years were recruited in 18 community health centers of Shenzhen city from March 1 to June 15, 2015 by a cluster sampling method. The results of genotype of HPV, liquid-based cytology (LBC), colposcopy and pathology were analyzed. The clinical sensitivity and specificity as well as positive (PPV) and negative (NPV) predictive values of the combination of different HPV genotype in screening the cervical intraepithelial neoplasia (CIN) 2 and above were estimated. Results: The HPV infection rate in Shenzhen area was 15.9% (432/2 717). The most common HPV genotype was HPV52 (22.9%), followed by HPV16 (12.7%), HPV53 (10.0%), HPV51 (8.6%) and HPV58 (8.1%). Compared with HPV16/18 genotyping, HPV33/16 genotyping had a higher sensitivity (57.1% vs. 42.9%, P<0.05) and an analogous specificity (87.3% vs. 86.9%, P>0.05) in predicting CIN2+ . The sensitivity of combination of HPV33/16 genotyping and low grade squamous intraepithelial lesion (LSIL) positive tested by LBC in predicting CIN2+ was 75.0%, significantly higher than 64.3% of atypical squamous cells of undetermined significance (ASC-US) positive tested by LBC alone (P<0.05). The specificities of these two methods mentioned above in predicting CIN2+ were 83.5% and 89.2%, respectively, without statistical difference (P>0.05). Conclusions Women infected by HPV have distinct risks for CIN2+ according to different high-risk HPV genotypes. The top five risks were HPV 33, 16, 58, 56, and 68. HPV-positive women triaged by LBC LSIL+ combined with HPV33/16 genotyping may be a potential strategy for cervical cancer screening in developed urban area.

Parkinson's disease with depression belongs to the category of "tremor syndrome" and "depression syndrome" of Traditional Chinese Medicine. Its syndrome characteristics and distribution are different from simple tremor syndrome and depression syndrome. Its neuroplastic mechanism involves dopamine, serotonin, norepinephrine and brain-derived neurotrophic factor. Parkinson's disease and depression have common neuro-biological mechanisms. Therefore, Chinese medicine treatment of Parkinson's disease with depression may have a dual regulation effect.

Liver depression and spleen deficiency syndrome is common in clinical practice. It has both the symptoms of uncomfortable liver depression and poor digestion of spleen deficiency. The brain-gut peptide not only regulates the gastrointestinal tract, but also participates in the regulation of mood, which is consistent with the mechanism of liver depression and spleen deficiency syndrome. At present, there are more than 10 brain-gut peptides discovered. This paper reviews several of these brain-gut peptides that are most closely related to liver depression and spleen deficiency syndrome to explore the relationship between brain-gut peptides and liver depression and spleen deficiency.
