Objective To identify and characterize the CD34~+ stem cells of hematopoietic tumor cell lines. Methods Taking CD34 molecule as a marker to identify if there are CD34~+ tumor cells in hematopoietic tumor cell lines(THP-1,MEL,K562,MOLT-4,RAJI,RPMI8226,SP2/0 and DCS) by fluorescence staining and FCM technology. We separated CD34~+ cells from K562 and MOLT-4 for further study.CD34~+ cells were cultured and observed their development.CD34~+ and CD34 +- cells were compared in their functional status(mRNA),cell cycles(G -0/G -1),their degree of differentiation(Id-1 expression) and their multi-drug resistance(gp expression). Results The percentages of CD34~+ cells were 6 ^2%(DCS),5.2%(MEL),1.4%(RAJI),2.5%(THP-1),2.1%(MOLT-4),3.1%(K562),0(SP2/0),and 0(RPMI8226) respectively.After culturing CD34 ++ cells isolated from K562 cells line could proliferate and the percentage of CD34 ++ reminded the same.CD34 ++ tumor cells contained much less RNA,more G0/G1 cells,expressed more Id-1 protein(less differentiated state) and possessed more P-gp(stronger multi-drug resistance).Conclusion There exists a very small portion of CD34 ++ stem cells among hematopoietic tumor cells and these cells are in a more primitive state.

Objective To explore a surgical therapy on close depressed fracture of the skull.Methods Ni-Ti form memory-alloy cramps were fixed on between the depressed bone and the normal surrounding skull in 16 patients with close depressed fracture of the skull.Results The follow up was 5～54 months(average 26 months).It indicated that there was no displacement and depressing of the fixed bone, no subcutaneous collection of fluid, no reject reaction and inflammation, and no erosion. The fixed bone and skull density showed normal by X ray and the fixed cramp did not disturb CT and MR scaning. All patients declared no mental burden and felt safe.Conclusion The Ni-Ti form memory-alloy cramp has a good mechanical restoration force and a good plastic effect,but no complication,it can increase the ability to resist external force in fracture region, and the surgical procedure is very simple, therefore it is ideal to treat the depressed fracture of skull.

Objective To investigate the association of interleukin-6 (IL-6) with depression using meta analysis. Methods A systematic literature search was conducted to examine depression and interleukin-6 in Chinese patients us-ing“depression”and“interleukin-6”in Databases including PubMed, CBM, VIP, CNKI and WanFang Data. A me-ta-analysis was performed to analyze correlation between depression and interleukin-6 using RevMan 5.2.8 software. Results A total of 9 studies were recruited, involving 432 depression patients and 277 healthy controls. The results of meta-analysis showed that concentration of IL-6 was higher in depression patients than in healthy controls(SMD=1.48, 95%CI:0.78~2.18,P<0.05). Subgroup analysis in the first-episode subgroup and the non first-episode subgroup showed that concentration of interleukin-6 was higher in depression patients than that in controls [the first-episode subgroup (SMD=1.94,95%CI:0.07~3.81,P<0.05), the non first-episode subgroup (SMD=1.26,95%CI:0.60~1.93,P<0.05)]. Conclusion There is a good correlation between depression and the serum IL-6 concentration. Due to the small number of studies and heterogeneity in different studies, the present meta-analysis has not yet confirmed the quantitative correla-tion between IL-6 and depression.

Objective:To master the current situation of prevention and control of drinking water-borne endemic fluorosis in Shandong Province, and to provide basic data for control and evaluation of drinking water-borne endemic fluorosis.Methods:From June to December 2019, in accordance with the requirements of the "National Drinking Water-Borne Fluorosis Monitoring Program (2019 Edition)" and "Shandong Province Drinking Water-Borne Fluorosis Monitoring Program (2019 Edition)", cross-sectional survey method was used to monitor the operation of the water supply projects, the fluorine content in drinking water, and the condition of children with dental fluorosis in all the disease affected villages of the drinking water-borne endemic fluorosis counties (cities, districts) in 16 cities of Shandong Province. Water fluorine was detected by "Standard Examination Methods for Drinking Water-Nonmetal Parameters" (GB/T 5750.5-2006), and in accordance with the "Standards for Drinking Water Quality" (GB 5749-2006), the water fluorine content was judged to be qualified or not. The examination and determination of dental fluorosis in children adopted "Diagnosis of Dental Fluorosis" (WS/T 208-2011), and the detection rate of dental fluorosis was calculated, the detection rates of dental fluorosis were compared between water improvement villages and villages without water improvement, qualified water fluorine and unqualified water fluorine villages.Results:There were 9 475 drinking water-borne endemic fluorosis villages in 105 counties (cities, districts) in Shandong Province, of which 9 370 were water improvement villages, and the water improvement rate was 98.89%. Among all the water improvement villages, there were 9 318 projects in normal operation, 45 intermittent projects and 7 scrapped projects. Among all the drinking water-borne endemic fluorosis villages, 8 254 villages were qualified in water fluorine, and the qualified rate of water fluorine was 87.11% (8 254/9 475); among water improvement villages, 8 210 villages were qualified in water fluorine, and the qualified rate of water fluorine was 87.62% (8 210/9 370); among the villages without water improvement, 44 villages were qualified in water fluorine, and the qualified rate of water fluorine was 41.90% (44/105). The qualified rate of water fluorine in water improvement village was significantly higher than that in villages without water improvement (χ 2 = 193.31, P < 0.05). The detection rates of dental fluorosis in children in water improvement villages and villages without water improvement were 8.92% (25 624/287 405) and 12.70% (271/2 134), respectively, and the detection rate of dental fluorosis in children in villages without water improvement was higher than that in water improvement villages (χ 2 = 37.23, P < 0.05). The detection rates of dental fluorosis in children in qualified water fluorine and unqualified water fluorine villages were 7.98% (20 200/253 082) and 15.62% (5 695/36 457), respectively, and the detection rate of dental fluorosis in children in unqualified water fluorine villages was higher than that in qualified water fluorine villages (χ 2 = 2 283.76, P < 0.05). Conclusions:Water improvement and fluorine reduction measures have been implemented in most drinking water-borne endemic fluorosis villages in Shandong Province, the detection rate of dental fluorosis in children in water improvement villages is lower than that in villages without water improvement. However, attention should be paid to the situation of water fluorine exceeding the standard and later management and maintenance to prevent the rebound of the disease.

OBJECTIVE: To explore the role of sinomenine in treatment of allergic rhinitis mice model and its possible mechanism. METHOD: We used ovalbumin (OVA) to make allergic rhinitis model of BALB/c mice. Saline was used in the control group. When we challenged the mice with OVA intranasally, the mice in sinomenine treatment group were feed by the food containing sinomenine. Mice were then killed 24 h after the last OVA challenge. The noses of mice from each group were removed en bloc and fixed, then each section was stained with hematoxylin and eosin. ELISA assay was used to measure the concentration of anti-OVA IgE, IL-4 and IFN-gamma. The proteins expressive level of T-bet and GATA3 were examined. RESULT: Nasal mucosa of the mice in sinomenine treatment group were not hyperplasia and without obvious infiltration of eosinophils. The concentration of anti-OVA IgE, IL-4 and IFN-gamma in the serum and T-bet and GATA3 expression levels of sinomenine treatment group were lower than those of allergic rhinitis group. CONCLUSION The sinomenine can be used to treat allergic rhinitis mice, and the mechanism may rely on the improvements of the Th1/Th2 imbalance.

Objective:To explore the application value of urine γ-synuclein (SNCG) in the diagnosis of bladder cancer.Methods:A total of urine samples from 129 patients with bladder cancer (malignant lesion group), 157 patients with urinary system benign lesions (benign lesion group), and 177 healthy people (the healthy control group) from January 2017 to April 2020 in the Fifth Clinical Medical College of Shanxi Medical University and Shanxi Provincial Cancer Hospital were collected. The concentration of SNCG in the collected urine was detected by using enzyme-linked immunosorbent assay. The receiver operating characteristic (ROC) curve was drawn to determine its sensitivity, specificity and accuracy for the diagnosis of bladder cancer.Results:The urine SNCG concentration in malignant lesion group [4.28 ng/ml (0.53-8.79 ng/ml)] was higher than that in healthy controls [1.44 ng/ml (0.56-3.51) ng/ml, H = 122.9, P < 0.01] and benign lesion group [1.97 ng/ml (0.51-5.87) ng/ml, H = 88.2, P < 0.01], and the concentration of urine SNCG in benign lesion group was higher than that in healthy controls ( H = 17.1, P < 0.01). ROC area under the curve (AUC) of urine SNCG in differentiating benign lesion group from healthy controls was 0.871(95% CI 0.819-0.923, P < 0.01), the best cut-off value was 2.79 ng/ml, the diagnostic sensitivity and specificity was 0.798 and 0. 977, respectively. AUC of urine SNCG in differentiating malignant lesion group from benign lesion group was 0.823(95% CI 0.769-0.877, P < 0.01), the best cut-off value was 3.54 ng/ml, the diagnostic sensitivity and specificity was 0.713 and 0.917, respectively. AUC of urine SNCG in differentiating malignant lesion group from healthy controls plus benign lesion group was 0.848 (95% CI 0.797-0.899, P < 0.01), the best cut-off value was 2.87 ng/ml, the diagnostic sensitivity and specificity was 0.791 and 0.901, respectively. Conclusions:The concentration of SNCG in urine of patients with bladder cancer is higher than that of patients with benign urinary lesions and healthy people. Urine SNCG has a good application value in the diagnosis of bladder cancer.

Objective To discuss the accuracy of three-dimensional (3D) sonography in diagnosing arcuate uterus and septate uterus and propose a quantitative indicator in distinguishing arcuate uterus and septate uterus.Methods Ninety-six patients with suspected congenital uterine malformation underwent 3D sonography to assess uterine anomalies at Obstetrics and Gynecology Hospital of Fudan University from August 2011 to March 2013.Uterine coronal section was reconstructed and measured in onmi view imaging mode of 3D sonography.Then qualitative diagnosis and categorization was done.The results were compared with diagnosis of hysteroscopy,hysteroscopy combined with laparoscope to determine the sensitivity,specificity,positive predictive values,negative predictive values and total accuracy of 3D sonography in diagnosing arcuate uterus,partial and complete septate uterus respectively.The variable was created in coronal section of uterus constructed through 3D imaging mode to differentiate arcuate uterus from septate uterus.Results There were 33 cases (34.4％,33/96) of arcuate uterus,54 cases (56.2％,54/96) of partial septate uterus and 9 cases (9.4％,9/96) of complete uterus in 96 cases diagnosed by 3D sonography.The accuracy of 3D sonography in diagnosing arcuate uterus and septate uterus was 86.5％.We concluded that 3D sonography had 100％ sensitivity,82.9％ specificity,60.6％ positive predictive value and 100％negative predictive value in the diagnosis of arcuate uterus.The sensitivity of 3D sonography for diagnosis of partial septate uterus was 80.6％,the specificity was 100％,the positive predictive value was 100％,and the negative predictive value was 69.1％.The sensitivity,specificity,positive and negative predictive values of 3D sonography for detecting complete septate uterus were all 100％.The ratio of depth of uterine internal indentation and depth from uterine fundus to the top of intemal indentation was more than 50％ for septate uterus,while less than 50％ for most of the arcuate uterus.Conclusions The diagnostic efficiency of 3D sonography in specific uterine malformation is different.The new quantitative indicator maybe helpful in improving the accuracy of 3D sonography in diagnosing arcuate uterus and septate uterus.

OBJECTIVETo survey the acceptance and willingness-to-pay for colorectal cancer colonoscopy screening among high risk populations in urban China.

METHODSFrom 2012 to 2013, a Cancer Screening Program in Urban China (CanSPUC) was initiated in 9 provinces, the current survey was conducted among those participants who were evaluated as "high risk for colorectal cancer" by a risk-factor-evaluation-model (community-based) and then went through a colonoscopy screening procedure (hospital-based). All the data were obtained through a questionnaire-based interview (face-to-face or self-completed), mainly focusing on the acceptance and willingness-to-pay of the participants for colorectal colonoscopy screening.

RESULTSThe current analysis included a total of 1 624 participants, with an median age of 55.0 years (P25 = 49.0, P75 = 61.0 years) and an annual income per capita of 17 thousand (range: 10-25 thousand) Chinese Yuan (CNY), 42.8% (695/1 624) of whom were males. Of all the participants, 87.0% (1 414/1 624) could totally or substantially accept the colonoscopy screening, particularly in those at higher education level (junior high school: OR = 0.34, 95% CI: 0.22-0.52; high school OR = 0.41, 95% CI: 0.26-0.66; college or over OR = 0.35, 95% CI: 0.20-0.59). Of all the participants, 13.0% (210/1 624) could not or hardly accept it, particularly in those with older age (60-69 years) (OR = 1.48, 95% CI: 1.06-2.07), not in marriage (OR = 2.15, 95% CI: 1.25-3.70) or with family member(s) to raise (OR = 1.60, 95% CI: 1.17-2.20). 1 388 (85.5%) of all the participants had willingness-to-pay for a long-term colonoscopy screening service, particularly in those working in public (OR = 0.61, 95% CI: 0.44-0.84) or enterprise sectors (OR = 0.60, 95% CI: 0.38-0.94), but 82.3% (1 141/1 386) of whom would only pay less than 100 CNY; 14.5% (236/1 624) of total had no willingness-to-pay, particularly in those living in areas with moderate (OR = 4.08, 95% CI: 2.75-6.33) or high GDP per capita (OR = 3.26, 95% CI: 2.11-4.92), or with an absence of willingness-to-pay for colonoscopy screening (OR = 3.98, 95% CI: 2.81-5.65).

CONCLUSIONSAlthough a larger community-based colorectal cancer screening program was warranted to examine the extrapolation of these findings, it suggested that the acceptance for colorectal cancer colonoscopy screening among the selected high-risk populations was considerable. The willing-to-pay was relatively high but the amount of payment was limited, the indicated subgroups with potentially less acceptance or willingness need to be more focused in the future to reach a higher participation rate. The data will also be informative in integrating the screening service into the local health insurance system.
