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.

Evaluating the prevalence of kidney damage according to population-based studies in different communities has been limited in developing countries. We conducted a population-based screening study in Uygur people of Urumqi, aiming to identify the prevalence and associated risk factors of chronic kidney disease (CKD) in Uygur populations. A total of 2576 residents (>18 years) from four districts of Urumqi were interviewed from June 2007 to January 2009 and tested for haematuria, albuminuria and reduced renal function. Associations between age, gender, smoking, diabetes mellitus, hypertension, hyperuricaemia and kidney damage were examined. There were 2576 subjects enrolled in this study. After age correction, the prevalence of albuminuria, haematuria and reduced estimated glomerular filtration rate (eGFR) was 3.58%, 2.26% and 1.03%, respectively. Approximately 5.65% of the sample population had at least one indicator of kidney damage. Age, diabetes mellitus, hypercholesteremia, hyperuricaemia and hyperlipidaemia were independently associated with CKD. In the general Uygur adult population from Urumqi, 5.65% had either proteinuria, haematuria or reduced eGFR, indicating the presence of kidney damage, with an awareness of only 1.05%. The high prevalence and low awareness of CKD in this population suggest an urgent need for CKD prevention programs in Uygur people.

Objective To investigate the prevalence of chronic kidney disease (CKD)and risk factors in the adult population of Tianshan district in Urumqi, Xinjiang. Methods A total of 2131 residents from 4 communities in Tianshan district of Urumqi city were randomly selected using a stratified, multistage sampling. All the residents were interviewed and tested for morning spot urine of albumin to creatinine ratio (ACR) (abnormal ≥ 30 mg/g), morning spot urine dipstick of hematuria ( abnormal ＞3 red blood cells/HP or greater) and pyuria ( abnormal＞ 5 white blood cells/HP) confirmed by microscopy. Renal function was determined with abbreviated MDRD equation [reduced estimated glomerular filtration rate (eGFR)＜60 ml ·min-1 ·(1.73 m2)-1]. The associations of kidney damage indicators with age, gender, hypertension, diabetes mellitus, income,education, cholesterol, triglyceride and smoking were examined. Results Eligible data of 2131 subjects were collected in the study. After the adjustment of age and gender component, the prevalence of albuminuria was found in 2.63％ (95％CI:1.78％-3.48％) of subjects, hematuria in 7.43％(95％CI:6.11％-8.75％) and reduced renal function in 1.72％(95％CI:1.08％-2.35％).Approximately 9.99％(95％CI:8.47％-11.55％) of subjects had at least one indicator of kidney damage. Multivariate logistic regression revealed that albuminuria, hematuria, age and hyperuricemia were independently associated with reduced renal function. Hematuria and reduced renal function were independently associated with albuminuria. Albuminuria, reduced renal function and female were independently associated with hematuria. Conclusion In urban adult population over 35 years old of Urumqi, a big city in western China, the prevalence of CKD is 9.99％, the recognition is 2.44％ and the risk factors of CKD are similar to those of other domestic big cities and western developed countries.

Ubiquitin specific protease 33 (USP33) is a multifunctional protein regulating diverse cellular processes. The expression and role of USP33 in lung cancer remain unexplored. In this study, we show that USP33 is down-regulated in multiple cohorts of lung cancer patients and that low expression of USP33 is associated with poor prognosis. USP33 mediates Slit-Robo signaling in lung cancer cell migration. Downregulation of USP33 reduces the protein stability of Robo1 in lung cancer cells, providing a previously unknown mechanism for USP33 function in mediating Slit activity in lung cancer cells. Taken together, USP33 is a new player in lung cancer that regulates Slit-Robo signaling. Our data suggest that USP33 may be a candidate tumor suppressor for lung cancer with potential as a prognostic marker.

Coronavirus disease 2019 (COVID-19) has become a worldwide pandemic. During the rapid spread time, it is a great challenge for patients with inflammatory bowel disease (IBD) who use immunosuppressive drugs from vaccination and drug application. This article is intended to supplement and revise the recommendations of the Inflammatory Bowel Disease Group of the Chinese Society of Gastroenterology in 2020 on the "Management of patients with inflammatory bowel disease during epidemic of novel coronavirus pneumonia", mainly including the treatment and vaccination of IBD patients complicated with COVID-19. It is expected to guide clinicians in drug use, vaccination of IBD patients at an appropriate time, also help patients getting through the epidemic period of COVID-19.

Beh?et′s syndrome is a kind of chronic systemic vasculitis with involvement of multiple organs. Intestinal involvement of Beh?et′s syndrome is presently named as intestinal Beh?et′s syndrome. Recently, there is considering another kind of disease type with only typical intestinal ulcers. Since it is difficult to differentiate intestinal Beh?et′s syndrome from Crohn′s disease, intestinal tuberculosis, intestinal lymphoma, and intestinal manifestations of many other autoimmune diseases, and there is limited evidence for the therapy of intestinal Beh?et′s syndrome, proposing diagnosis and treatment recommendations for intestinal Beh?et′s syndrome through evidence-based judgment will be of great significance for clinical practice.
