Abstract
PURPOSE This study analyzes the relationship between human papillomavirus (HPV) infection, vaginal microecology, and cervical lesions to provide a basis for the prevention and treatment of cervical cancer (CC) in the Xinjiang region. METHODS Real-time quantitative PCR was used for HPV genotyping and viral load. The Gram staining and dry biochemical enzyme kit were utilized to diagnose vaginal secretions. The χ2 test and Logistic regression analysis were used for statistical analysis. RESULTS The HPV infection rate among women in the Xinjiang region was 30.29%, of which the single HPV infection accounts for 77%. HPV16 and HPV52 were the main infection types. There was significant differences in the HPV infection rate and infection types among the Han, Uighur, Hui, and Kazakh ethnic groups. The viral load of HPV16 and HPV52 increases with the upgrade of cervical lesions. There were significant differences in vaginal microecology evaluation indicators H2O2, SNA, LE, GUS, trichomonas, clue cells, and lactobacilli among different ethnic groups. HPV negative patients with varying grades of cervical lesions exhibit a notable variance in H2O2 and LE, which is statistically significant. Single HPV infection and high viral load HPV significantly increase the risk of CC. CONCLUSIONS This study indicates that HPV infection and vaginal microecology differ among ethnic groups, which have a strong correlation with the progression of CC, offering guidance on CC screening and interventions in the Xinjiang area.

Abstract
Objective: To investigate the histological features and prognostic factors of angioimmunoblastic T-cell lymphoma (AITL). Methods: The pathological data of 62 patients with AITL with complete follow-up information were retrospectively collected and analyzed from Changhai Hospital during September 2012 and September 2017. Histological and immunohistochemical (IHC) examination, in situ hybridization (ISH), and single nucleotide polymorphisms (SNP) gene mutation analysis were done. Subgroup evaluation with histology, IHC, ISH, SNP gene mutation, and association with clinical progression were performed. Results: The cohort included 62 cases of AITL, including 46 males and 16 females patients, with a median age of 64 years. Follicular dendritic cells (FDC) area showed significantly expansion (≥30%) in 40 cases; increased plasma cells (≥10%) was seen in 37 cases; B cells were distributed around blood vessels in 37 cases; and increased p53 mutation positive cells (≥40%) were seen in 39 cases; high Ki-67 index (≥40%) was seen in 39 cases; RHOA mutation was seen in 19 cases; TET2 mutation was seen in 9 cases. Overall survival analysis showed these factors were significantly correlated with tumor prognosis (P<0.05). Multivariate analysis showed that CD38 positive cells<10%, Ki-67≥40%, RHOA and TET2 mutations were risk factors associated with overall survival. Conclusions: AITL could be divided into two different prognostic groups, low-grade and high-grade, with statistically significance outcome, based on the FDC area expansion, degree of plasma cell proliferation, B cells distribution pattern combined with gene mutations and clinical progression. Low-grade malignant group progresses slowly, and high-grade malignant group is highly invasive.

Abstract
Objective: To compare different specimen types of lung adenocarcinoma in the detection of epidermal growth factor receptor (EGFR) gene and to correlate EGFR mutations with patient clinical features. Methods: One hundred lung adenocarcinoma cases were collected from June to December in 2015, at the First Affiliated Hospital of Xinjiang Medical University.Of the 100 lung adenocarcinoma samples, 43 were male and 57 were female. The age was from 40 to 88 years old, and the average age was 66 years. One hundred lung adenocarcinoma cases were divided equally into two groups. Mutation analysis of EGFR gene by real-time PCR was performed using biopsied tissue and paired blood samples in one group (n=50) and using pleural effusion and paired blood samples in the other group (n=50). Results: The mutation rate of EGFR gene in biopsy samples was 54% (27/50) , higher than that of blood samples (46%, 23/50), but without statistical differences (χ(2)=0.640, P=0.424). In contrast, mutation rate of EGFR gene in pleural effusion samples (42%, 21/50) was higher than that of blood samples (34%, 17/50), but without statistical differences(χ(2)=0.679, P=0.409). Two patients had EGFR mutation detected in paired blood samples but not in the corresponding biopsy samples, and four patients had EGFR mutation detected in pleural effusion samples but not in their paired blood samples. The mean progression-free survival of patients with detectable EGFR mutation were 9.5 months (tissue samples), 8.6 months (pleural effusion) and 8.5 months (blood). However, there was no statistical difference. Conclusions: Blood samples may be used to assess EGFR mutations for patients with lung adenocarcinoma. However, further studies are needed to improve the sensitivity and accuracy in the detection of EGFR mutations using blood samples.

Abstract
Objective: To investigate the role of PRDM1 gene inactivaion in the regulation of C-MYC in diffuse large B-cell lymphoma (DLBCL), and to explore the correlation of its immunophenotype and prognosis. Methods: 100 cases paraffin-embedded DLBCL tissues were collected from January 2009 to December 2015 at the First Affiliated Hospital of Xinjiang Medical University along with 20 cases of reactive proliferative lymph nodes as control. Immunohistochemical methods were used to detect the expression of CD20, CD10, MUM1, Ki-67, bcl-6, PRDM1/Blimp1, C-MYC and PAX5 protein. The tumors were classified into two subtypes according to Hans classification.The expression of PRDM1 and C-MYC gene in tumor group and control group was detected by reverse transcription PCR (RT-PCR) and the relationship between PRDM1 and C-MYC gene was analyzed.OCI-LY1 (GCB subtype) and OCI-LY3 (non-GCB subtype) cell lines were transfected with small interfering RNA by cationic liposome reagent transfection, and the expression of C-MYC in the transfected cell lines was detected by RT-PCR and Western blot. The Kaplan-Meier method was used to analyze the prognostic significance of PRDM1/Blimp1 and C-MYC at protein and mRNA levels. Results: There were 27 cases of GCB subtype and 73 cases of non-GCB subtype according to Hans classification. The positive expression of Blimp1 in DLBCL group and proliferative lymph nodes in control group was seen in 26(26.0%) and 20 cases(100%), respectively. There were 58 cases with high expression of PRDM1 at mRNA level, including 22 cases of GCB subtype and 36 cases non-GCB subtype, and the difference was statistically significant (P=0.004). There were differences in PRDM1 gene expression between the two immunological subtypes, serum lactate dehydrogenase (serum LDH) level, presence of B symptoms, tumor primary sites and other clinical pathological parameters, while C-MYC expression was different in gender, IPI score, and serum LDH levels. Upon PRDM1/Blimp1 gene silencing in the two cell lines, C-MYC protein and gene expression were up-regulated in the transfection group, compared with the blank control group and negative control group by reverse transcription PCR and Western blot analyses. Moreover, PRDM1 expression was significantly associated with C-MYC(χ(2)=7.648, P=0.006) at mRNA level. Conclusion: The up-regulation of C-MYC gene expression induced by PRDM1 inactivation in DLBCL may play an important role for the development of DLBCL.PRDM1 protein and mRNA are associated with immunophenotyping and PRDM1 mRNA is a marker of poor prognosis.

Abstract
Objective: To investigate PRDM1 gene methylation status, immune classification and their prognostic significance in diffuse large B cell lymphoma (DLBCL). Methods: Immunohistochemical (IHC) staining for CD20, CD10, bcl-2, bcl-6, PRDM1/Blimp-1 and MUM1 was carried out in 100 cases of DLBCL specimens and 20 reactive lymphoid proliferation samples. All patients were classified into germinal center B cell-like (GCB) and activated B cell-like (ABC) subtype according to Hans' algorithmin. PRDM1 gene methylation was detected by methylation-specific PCR (MSP) and its relationship with clinicopathologic parameters was analyzed. OCI-Ly1 (GCB type) and OCI-Ly3 (ABC type) cell lines were transfected by Small interfering RNA(siRNA) with cationic lipid reagent transfection mediated, and the PRDM1/Blimp-1 expression in before and after transfected cell lines were detected with reverse transcription-PCR and Western blot methods. The relationship between PRDM1 gene methylation, clinicopathologic parameter and survival was analyzed using one-way analysis of variance. Results: One hundred patients were classified into 73 (73%) cases of GCB subtypes and 27 (27%) cases of ABC. PRDM1/Blimp-1 was expressed in 21 DLBCL and highly expressed in 20 reactive lymphoid proliferation. PRDM1 gene methylation was detected in 23% (23/100) of DLBCL, while no methylation was detected in all 20 reactive lymphoid proliferation. The difference of the PRDM1 methylation status between DLBCL and the control samples was statistically significant (P=0.004). However, there was no significant correlation between the PRDM1 gene methylation and clinicopathologic parameters (P>0.05). Reverse transcription-PCR and Western blot showed that PRDM1 gene expression was reduced in siRNA-induced group compared with blank control group and negative control group. One-way analysis of variance revealed that aged ≥60 years, performance status score above 3, and the presence of general symptoms were associated with significantly lower overall survival rate. Conclusions: PRDM1 gene silencing with aberrant CpG methylation is probably one of the critical events in the oncogenesis of DLBCL. This may have important implications as a candidate marker for diagnosis and targeted gene therapy. Meanwhile in vitro siRNA transfected OCI-Ly1 and OCI-Ly3 cell lines confirm that PRDM1 gene is a suppressor gene in DLBCL and may represent a novel therapeutic target.

Abstract
Objective: To investigate clinicopathologic characteristics, immunophenotype and EB virus-related molecular genetic alterations in primary central nervous system diffuse large B cell lymphoma (DLBCL) along with correlation with clinical prognosis. Methods: A total of 30 cases of primary central nervous system DLBCL were retrospectively studied by retrieving clinical data, histological evaluation and immunophenotyping by EnVision two steps methods. The expression of EBER mRNA was detected by in situ hybridization and bcl-2, bcl-6 and C-MYC gene abnormalities were analyzed by interphase fluorescence in situ hybridization. Results: The cases included 18 males and 12 females (sex ratio of 1.5∶1.0) with an age ranging from 24 to 78 years (average age of 52 years, the median age of 53 years). The single primary clinical presentation was focal neurologic deficits. Tumor locations were supratentorial (21 cases), subtentorial (7 cases), involving both locations in 2 cases. Diffuse growth pattern was observed with large lymphoid cells mostly resembling centroblasts with abundant basophilic cytoplasm with oval to round, vesicular nuclei containing fine chromatin. An angiocentric and angiodestructive growth pattern was also present. Other features included perivascular space invasion. Immunohistochemical staining using a panel of CD10, bcl-6 and MUM1, six cases were germinal center-like (GCB) and 24 cases were non-germinal central-like (non-GCB). The positive rates of bcl-2, bcl-6 and C-MYC were 53.3% (16/30), 80.0% (24/30) and 20.0% (6/30), respectively. Genetic alterations were detected by FISH and the gene arrangement rates of bcl-2, bcl-6 and C-MYC were 3.3% (1/30), 16.7% (5/30) and 3.3% (1/30), respectively. There were 19 cases in stage 0-1 disease and 11 cases had stage 2-3 disease. Postoperative follow-up for average 13.6 months showed the median survival of 10 months, one-year survival of 46.7% and 16 patients died within a year. Conclusions: The clinical prognosis of primary central nerve system DLBCL depends on age, clinical performence status score, IPI score, immune classification and treatment. Patients typically progress rapidly with the high mortality within one year of diagnosis. Surgical resection combined with high-dose methotrexate or cytarabine chemotherapy offer the best treatment option.

Abstract
OBJECTIVES Microbiota has been suggested in promoting chronic inflammation in human tissues which, in turn, promotes tumor development. This study tests a hypothesis that high-risk human papillomavirus (HR-HPV) infection may correlate with proinflammatory Stat3 signaling activities and IL-17 levels in breast cancer (BC) patients. MATERIALS AND METHODS This study examined HPV infection by GenChip technology, constitutively active Stat3 (p-Stat3) and IL-17 levels by immunohistochemistry (IHC) using specific antibodies in 379 BC patients, together with 245 paired adjacent breast adenosis (ABA) tissues and 100 unrelated breast adenosis (BA) tissues. RESULTS We obtained four major findings: (1) HR-HPV16/18 infections existed in 10.5% (34/325) of BC issues, higher than control BA tissues (4%, 4/100, P = 0.047). (2) Using IHC methodology, BC tissues showed more overactive p-Stat3 (2+/3+, 38.5%, 146/379) than ABA tissues (27.3%, 67/245, P < 0.001); similarly, BC also had more tissues overexpressing IL-17 (2+/3+, 61.5%, 233/379) than ABA tissues (51.8%, 127/245, P < 0.001). (3) High levels (2+/3+) of both active p-Stat3 and IL-17 correlated with poor differentiation and lymph nodal metastasis in BC (both with P < 0.05), but not with patients' prognosis. (4) HR-HPV infections correlated with both active p-Stat3 (P = 0.018) and its downstream IL-17 levels (P = 0.021) in BC tissues. CONCLUSION There may be a possible tri-lateral relationship among HPV infection, constitutive Stat3 activity and IL-17 level, whose collaborations could orchestrate a proinflammatory microenvironment in breast tissues by which promote carcinogenesis and/or facilitate progression of breast cancer.

Abstract
OBJECTIVE To investigate the incidence of BRCA1/2 gene mutation among triple negative breast cancer (TNBC) patients. METHODS Polymerase chain reaction and DNA sequencing were used to detect mutations of BRCA1 (exons 2, 11 and 20) and BRCA2 (exon 11) genes using paraffin-embedded tissue samples of 33 TNBC patients (21 Uyghur patients and 12 Han patients ) in Xinjiang Uygur Autonomous Region. RESULTS Among 33 cases of TNBC, 5 cases (5/33, 15.2%) were found to have BRCA1 gene mutation. The exon 11 of BRCA1 gene mutation proportion was seen in 4/5 and exon 20 of BRCA1 gene mutation proportion was seen in 1/5. No germline mutation was found in exon 2 of BRCA1 gene and exon 11 of BRCA2 gene. The onset age of patients with BRCA1 mutations were younger than 50 years. Four BRCA1 mutation patients were premenopausal. The proportions of BRCA1 gene mutation of Uygur TNBC patients and Han TNBC patients were 2/12 and 3/21, respectively, without significant difference (P=0.854). BRCA mutations were mainly found in stageⅠtoⅡ (4/5) and only 1 case (1/5) was found with stage Ⅲ disease. No significant difference was found in fertility status, menstrual status and age at menarche between mutated and non-mutated patients (P>0.05) . CONCLUSIONS Germline mutation of BRCA1 may be more often associated with TNBC than BRCA2 for its higher mutation rate. Compared with non-mutated TNBC cases, several clinicopathologic features could be identified among mutated cases.

Abstract
BACKGROUND The pandemic of obesity is a global public health concern. Most studies on obesity are skewed toward high-income and urban settings and few covers low-income populations. This study focused on the prevalence of overweight and obesity and their correlations with blood lipids/metabolites/enzymes (bio-indicators) in a rural community typical of low-income in remote western China. METHODS This study was performed in a Muslim ethnic Uyghur rural community in Kashi Prefecture of Xinjiang, about 4,407 km (2,739 miles) away from Beijing. Body mass index (BMI) and major blood bio-indicators (25 total items) were measured and demographic information was collected from 1,733 eligible healthy women aged 21 to 71 yrs, of whom 1,452 had complete data for analysis. More than 92% of the women lived on US$1.00/day or less. According to the Chinese criteria, overweight and obesity were defined as BMI at 24 to <28 kg/m(2) and at ≥ 28 kg/m(2), respectively. RESULTS The average BMI among these low-income women was 24.0 ± 4.0 (95% CI, 17.5-33.7) kg/m(2). The prevalence of obesity and overweight was high at 15.1% and 28.9%, respectively. Among 25 bio-indicators, BMI correlated positively with the levels of 11 bio-indicators including triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TCHOL), glucose (GLU), and uric acid (UA); but negatively with the levels of 5 bio-indicators including high-density lipoprotein cholesterol (HDL-C) and apolipoprotein A/B (APO A/B). CONCLUSIONS This is the first investigation reporting overweight and obesity being common in low-income Muslim Uyghur women, whose BMI correlates with several important blood bio-indicators which are risk factors for diabetes and cardiovascular diseases. These findings may help make preventive public health policies in Uyghur communities. To prevent diabetes and cardiovascular diseases in low-income settings, we therefore propose a cost-effective, two-step strategy first to screen for obesity and then to screen persons with obesity for diabetes and cardiovascular diseases.
