Objective: To investigate the health-seeking delay in tuberculosis among school students in Yining City, Xinjiang Uygur Autonomous Region from 2009 to 2020, and analyze the influencing factors, so as to provide the evidence for reducing the health-seeking delay in tuberculosis among students in Yining City. Methods: The demographic features and diagnosis of students with tuberculosis in Yining City from 2009 to 2020 were retrieved from the Tuberculosis Management Information System of the Chinese Disease Control and Prevention Information System, and the factors affecting the health-seeking delay in tuberculosis were identified using the multivariable logistic regression analysis. Results: A total of 443 students with tuberculosis were reported in Yining City from 2009 to 2020, including 209 boys and 234 girls, with a male/female ratio of 1∶1.12. There were 29 primary school students ( 6.55% ), 81 junior high school students ( 18.28% ), 187 high school students ( 42.21% ) and 146 college students ( 32.96% ) reporting tuberculosis, and 394 cases ( 88.94% ) had locally registered residence. There were 287 students with health-seeking delay in tuberculosis ( 64.79% ), and the median duration of health-seeking delay was 35 ( interquartile range, 33 ) days. Multivariable logistic regression analysis showed that registered residence ( local, OR=1.899, 95%CI: 1.004-3.591 ) and origin of tuberculosis patients ( clinical consultation, OR=3.448, 95%CI: 1.755-6.775; recommendation for symptoms, OR=3.215, 95%CI: 1.161-8.900; tracking, OR=2.415, 95%CI: 1.269-4.596 ) and diagnostic results ( positive sputum smears, OR=3.081, 95%CI: 1.710-5.551 ) statistically correlated with health-seeking delay among students with tuberculosis. Conclusions The proportion of health-seeking delay in tuberculosis was high among students in Yining City from 2009 to 2020; registered residence, origin of tuberculosis patients and diagnostic results were associated.

Objective: To analyze the association between hepatitis B virus (HBV) infection and pancreatic cancer. Methods: Retrospective analysis was performed to explore the positive rate of serum hepatitis B virus surface antigen (HBsAg) in patients with pancreatic cancer, lung cancer, diabetes mellitus and general population. Z test was used to compare the rate of HBV infection between the samples and general population. The rates among the samples were compared by Chi-square test. Results: A total of 3,701 registered patients seen in our hospital between January 1st 2003 and March 31st 2009 were collected. There were 230 pancreatic cancer patients with a positive rate of serum HBsAg of 16.1%, 1,188 lung cancer patients with a positive rate of serum HBsAg of 10.7%, and 2,283 patients with diabetes mellitus with a positive rate of serum HBsAg of 11.6%. There was no statistical significance in Z-test results between lung cancer patients and general population (Z=1.104, P=0.163), but the Z-test results between patients with diabetes mellitus and general population showed a statistical significance (Z=2.98, P=0.002). The positive rate of HBsAg was higher in pancreatic cancer patients than that in lung cancer patients (OR=1.60, 95% Cl: 1.077-2.382, r=5.487, P=0.019). Similar results were found between pancreatic cancer patients and diabetic patients (OR=1.46, 95% CI: 1.004-2.123, r=3.965, P=0.046). Conclusion: The positive rate of HBsAg is high in pancreatic cancer patients. There might be an association between HBV infection and pancreatic cancer.

Objective: To investigate the prevalence and influencing factors of latent tuberculosis infection (LTBI) among freshmen in a vocational college in Xinjiang Uygur Autonomous Region, so as to provide insights into tuberculosis control in vocational colleges. Methods : All freshmen enrolled in a vocational college in Xinjiang Uygur Autonomous Region in 2020 were recruited and participants' demographics, life style, history of tuberculosis contacts, frequency of ventilation and disinfection in dormitories and classrooms and awareness of core tuberculosis control knowledge were collected through questionnaire surveys. LTBI was detected among freshmen by means of purified protein derivative test (PPD skin test) and chest X-ray scans, and the factors affecting LTBI were identified using a multivariable logistic regression model. Results: A total of 5 463 freshmen were screened for LTBI, with a screening rate of 100.00%, and the participants included 2 151 men and 3 312 women, with a male/female ratio of 0.65︰1, and had a mean age of (16.83±1.05) years. A total of 388 freshmen were detected with LTBI, with a detection rate of 7.10%, and no active pulmonary tuberculosis was detected. The prevalence of LTBI was 9.44% in men and 5.59% in women. Multivariable logistic regression analysis identified males (OR=1.587, 95%CI: 1.281-1.965), smoking (OR=2.108, 95%CI: 1.355-3.278) and a history of tuberculosis of families (OR=2.851, 95%CI: 1.615-5.034) as risk factors for LTBI among freshmen, and knowing core tuberculosis control knowledge as a protective factor of LTBI among freshmen (OR=0.276, 95%CI: 0.218-0.350). Conclusions The risk of LTBI was associated with gender, smoking, history of tuberculosis of families and understanding of the core tuberculosis control knowledge among freshmen in this vocational college in Xinjiang Uygur Autonomous Region. Health education about the core tuberculosis control knowledge is recommended to be reinforced among students in vocational colleges in Xinjiang Uygur Autonomous Region.

The central nervous system (CNS) plays a key regulatory role in glucose homeostasis. In particular, the brain is important in initiating and coordinating protective counterregulatory responses when blood glucose levels fall. This may due to the metabolic dependency of the CNS on glucose, and protection of food supply to the brain. In healthy subjects, blood glucose is normally maintained within a relatively narrow range. Hypoglycemia in diabetic patients can increase the risk of complications, such as heart disease and diabetic peripheral neuropathy. The clinical research finds that the use of traditional Chinese medicine (TCM) has a positive effect on the treatment of hypoglycemia. Here the authors reviewed the current understanding of sensing and counterregulatory responses to hypoglycemia, and discuss combining traditional Chinese and Western medicine and the theory of iatrogenic hypoglycemia in diabetes treatment. Furthermore, the authors clarify the feasibility of treating hypoglycemia on the basis of TCM theory and CNS and have an insight on its clinical practice.

Objective To observe curative effect and clinical outcome in 30 recipients undergoing allogcneic peripheral blood stem cell transplantation (PBSCT) combined with bone marrow transplantation (BMT). Methods 30 patients with a median age of 32.6 years underwent allo-HSCT, of which 11 patients with AML, 14 patients with ALL, and 5 patients with CML They all have a HLA-identical sibling. PBSCswere mobilized with G-CSF. Three hundreds milliliter bone marrow blood was transplanted to the patients on the day that the PBSC was transplanted. Amended Bu/Cy was used as the conditioning regimen. MTXcombined with CsA and MMF was used as GVHD prophylaxis. Results A median number of mononuclear cells of (5.13±2.6)x10~8/kg recipient's weight was collccted from peripheral blood, and (1.3±0.6)x10~8/kgrecipient' s weight from bone marrow blood. Engraftment of neutrophils and platelets was achieved at a median of (12.1±3.25) days and (14±5.33) clays respectively. Ⅰ - Ⅱ acute GVHD occurred in 40.0 % cases,Ⅲ - Ⅳ acute GVHD occurred in 3.3 % cases, and chronic GVHD developed in 43.3 % cases. Severe cGVHD developed in 3.3% cases. The 2 years disease free survival rate (DFS) by the day of transplantation was 72.0 %. Conclusion PBSCT combined with BMT was effective to cure leukemia. The results also suggested that PBSC recipients had an lower incidence of aGVHD and cGVHD as compared with previous reports.

Objective To analyze the clinical features and prognosis of CD34-positive and CD34-negative adult patients with acute T-lymphoblastic leukemia (T-ALL),and to explore the value of CD34 expression for prognosis of patients with T-ALL.Methods 75 adult patients diagnosed with T-ALL from January 2012 to July 2015 in the Department of Hematology,the First Affiliated Hospital of Zhengzhou University,were analyzed retrospectively.According to the expression of CD34,the patients were divided into CD34-positive group and CD34-negative group,and then the clinical characteristics and prognosis of both groups were analyzed.Results In 75 patients,CD34-positive group had 24 (32.0 ％) patients and CD34-negative group had 51 (68.0 ％) patients.Between the two groups,there was no significant difference in these factors,such as sex,age,infiltration of liver,spleen and lymph nodes,thrombocytopenia,high white blood cell count,abnormal karyotype,complete remission within 4 weeks and central nervous system leukemia (CNSL).The proportions of patients with hemoglobin (Hb) ＜ 90 g/L and expression of myeloid lineage marker were higher in the CD34-positive group than those in the CD34-negative group (x2 =5.888,P=0.015;x2 =10.758,P =0.001,respectively).There were only 18 patients treated with hematopoietic stem cell transplantation (HSCT),57 patients were not.In patients without HSCT,the median survival time in the CD34-positive group and CD34-negative group was significant different (5 months vs.32 months,x2 =9.172,P =0.002).Conclusions CD34 expression in adult patients with T-ALL appears to be associated with Hb ＜ 90 g/L and the expression of myeloid lineage markers.For the patients without HSCT,CD34 is likely negatively related with the prognosis.

Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost

Objective:To describe demographic,clinical and physiological characteristics,treatment between first-episode major depressive disorder(MDD)and relapse MDD,and to explore characteristics of relapse MDD.Methods:Totally 858 patients who met the diagnostic criteria for depression of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5),were included by using the Mini International Neuropsychiatric Interview(MINI),Clinician-Rated Dimensions of Psychosis Symptom Severity,and Hamilton Depression Scale etc.Among them,529(58.6％)were first-episode depression and 329(36.0％)were relapsed.The differences of demographic characteristics,clinical and physiological characteristics,treatment were compared byx2test and Kruskal-Wallis rank sum test.Multivariate logistic regression was used to explore the characteristics of MDD recur-rence.Results:Compared to first-episode MDD,relapse MDD had more comorbidity(OR=2.11,95％CI:1.00-4.44),more days out of role(OR=1.26,95％CI:1.01-1.56),more history of using psychiatric drug more than one month(OR=1.41,95％CI:1.02-1.97)and electroconvulsive therapy(OR=3.23,95％CI:1.42-7.36),and higher waist-hip ratio(OR=33.88,95％CI:2.88-399.32).Conclusion:Relapse MDD has positive as-sociation with comorbidity of mental disorders,out of role,and higher waist-hip ratio.
