Objective: To investigate the trends in mortality of malignant tumors in Ningbo City, Zhejiang Province from 2002 to 2022, so as to provide the evidence for formulating malignant tumor control strategies in Ningbo City. Methods The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC). Methods: The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC). Results: The crude mortality of malignant tumors was 186.43/105 to 221.24/105 in Ningbo City from 2002 to 2022, which showed a tendency towards a rise (AAPC=0.76%), and both the Chinese- (AAPC=-2.64%) and world-standardized mortality (AAPC=-2.74%) appeared a tendency towards a decline (all P<0.05). The world-standardized mortality of malignant tumors presented three changes in Ningbo City from 2002 to 2022, with a more remarkable decline from 2011 to 2018 (APC=-3.53%) than from 2002 to 2011 (APC=-2.10%) and from 2018 to 2022 (APC=-2.00%) (all P<0.05). The annual decline in mortality of malignant tumors was higher in men (Chinese-standardized mortality: AAPC=-2.68%; world-standardized mortality: AAPC=-2.75%) than in women (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%), and higher in urban areas (Chinese-standardized mortality: AAPC=-2.85%; world-standardized mortality: AAPC=-2.92%) than in rural areas (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%) (all P<0.05). The mortality of malignant tumors appeared a tendency towards a rise with age in Ningbo City, with the highest mortality in residents at ages of 85 years and older (1 447.13/105). Death from malignant tumors were responsible for 31.86% of all causes of death in Ningbo City, and the five most common causes of cancer death included lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer. In addition, the world-standardized mortality of pancreatic cancer (AAPC=3.92%), prostate cancer (AAPC=4.71%), and cervical cancer (AAPC=1.60%) appeared a tendency towards a rise in Ningbo City (all P<0.05). Conclusions The crude mortality of malignant tumors appeared a tendency towards a rise in Ningbo City from 2002 to 2022, while the standardized mortality showed a tendency towards a decline. Management of malignant tumors should be given a high priority among men and rural residents, and lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer should be emphasized.

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R² of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Objective: To investigate the trends in incidence and mortality of gastric cancer in Ningbo City, Zhejiang Province from 2011 to 2022, so as to provide insights into improving gastric cancer control strategy. Methods: The incidence and mortality of gastric cancer in Ningbo City from 2011 to 2022 were collected through Ningbo Municipal Chronic Disease and Cause of Death Monitoring System. The incidence and mortality of gastric cancer were calculated, and standardized by the data from the Sixth Chinese National Population Census in 2020 (Chinese-standardized rate) and the world standard population first introduced by Segi in 1960 (world-standardized rate). The trends in incidence and mortality of gastric cancer were evaluated using annual percent change (APC) and average annual percent change (AAPC). Results : The crude incidence of gastric cancer was 45.69/105 in Ningbo City from 2011 to 2022, with no significant changing patterns seen during the study period (AAPC=-0.02%, P>0.05), and the Chinese- and world-standardized incidence of gastric cancer was 28.61/105 and 21.87/105, which both appeared a tendency towards a decline (AAPC=-3.19% and -3.05%, both P<0.05). The crude, Chinese-standardized and world-standardized mortality rates of gastric cancer were 28.56/105, 17.07/105 and 12.57/105, respectively, all showing a tendency towards a decline (AAPC=-3.00%, -6.26% and -6.34%, all P<0.05). The Chinese- and world-standardized incidence and mortality of gastric cancer all appeared a tendency towards a decline in urban (AAPC=-2.72%, -2.53%, -5.91% and -5.96%, all P<0.05) and rural areas (AAPC=-3.61%, -3.53%, -6.79% and -6.89%, all P<0.05), and the Chinese- and world-standardized incidence and mortality of gastric cancer were significantly higher among urban residents than among rural residents. The Chinese- and world-standardized incidence and mortality of gastric cancer all appeared a tendency towards a decline among men (AAPC=-3.18%, -3.00%, -5.82% and -5.91%, all P<0.05) and women (AAPC=-2.98%, -2.90%, -7.12% and -7.12%, all P<0.05), and the Chinese- and world-standardized incidence and mortality of gastric cancer was significantly higher among men than among women. In addition, the crude incidence and mortality of gastric cancer both appeared a tendency towards a rise with age among residents in Ningbo City (both P<0.05). Conclusions The incidence and mortality of gastric cancer both appeared a tendency towards a decline in Ningbo City from 2011 to 2022; however, the incidence and mortality remained high. Males and urban residents should be given a high priority for gastric cancer control, and gastric cancer screening should be strengthened among individuals at ages of 40 years and older.

A survey was conduct to analyze the usage situation of post-exposure prophylaxis(PEP) and related factors among men who have sex with men(MSM) in 6 cities of Shandong Province. Total of 2 620 subjects, the use ratio was 2.98% (78/2 620). Compared with age≤24 years,monthly income<5 000 yuan,non-commercial sex, non-DU,non-STD,role for being insert in the anal intercourse,MSM was more likely to use PEP with age≥45 years(OR=3.87, 95%CI:1.12-13.36),monthly income≥5 000 yuan(OR=1.87, 95%CI:1.07-3.28),commercial sex (OR=3.13, 95%CI:1.56-6.28), drug users (DUs) (OR=4.63, 95%CI:2.51-8.52),STD patient (OR=2.35,95%CI:1.05-5.27),the mixed sex role group(OR=2.25,95%CI:1.10-4.62).

Objective: To understand the characteristics and depressive status of men who have sex with men (MSM) who self-reported HIV infection through heterosexual transmission and to provide evidence for personalized management of HIV infected people. Methods: A cross-sectional survey was carried out in Shandong province from September to December in 2019. Male HIV patients aged ≥15 years who self-reported HIV infection through heterosexual transmission were selected to verify the route of infection by one-to-one interview in Ji'nan, Qingdao, Weifang and Linyi cities of Shangdong province. According to the 1∶1 ratio, local HIV patients with age difference ≤3 years who self-reported MSM were selected as controls. A questionnaire survey was conducted, including data on demographic characteristics, behavior status, CES-D and PSSS. The related factors of the depressive symptoms and characteristics were analyzed. Results: A total of 373 male HIV patients were interviewed, and 39.7%(148/373) were confirmed as MSM after reexamination. The interviewers were: aged (40.3±12.0) years old, 41.9% (62/148) married/cohabiting. 27.0% (40/148) had been tested before HIV diagnosis, 71.6% (106/148) had homosexual partners ≥2 and 55.4% (82/148) had depressive symptom. Multivariate analysis showed that the MSM without HIV testings before diagnosis, had homosexual partners ≥2 before diagnosis, had first homosexual behavior at the age >30 years old and with depressive symptoms were more likely to conceal the true infection route. The incidence of depression among MSM who self-reported HIV infection through heterosexual transmission was related to physical health status social support and occupational stability. Conclusions: Some male HIV persons self-reported as being heterosexually transmitted were really transmitted through homosexual behavior. There were high-risk behaviors such as multiple partners and intersex among this group, and with high incidence of depression. It is necessary to encourage the reexamination program during follow-up and target on psychological and behavioral interventions, continuously.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

Aim To evaluate the effect of ZST93 on the proliferation in human chronic myeloid leukemia(CML)cells(K562)and explore the possible mechanism.Methods MTT assay, cell growth curve and inverted microscope were used to investigate the effect of ZST93 on proliferation of K562 cells.Cell transfection and Western blot were performed to detect the autophagy, while PI staining, Annexin V-FITC/PI and flow cytometry were conducted to determine cell apoptosis and its anticancer mechanism.Results ZST93 could significantly inhibit the proliferation of K562(IC50=2.59 μmol·L-1)and induce cell cycle arrest at G1-phase in a dose- and time-dependent manner.Also, through leading to accumulation of GFP-LC3, transition into LC3- II from LC3- 1 , and decrease of p62 expression, ZST93 induced autophagy initiation and autophagic flux.Furthermore, ZST93 induced extrinsic apoptotic pathway by activating caspase-8, and further promoted the cleavage of apoptosis related proteins including caspase-9, caspase-3 and PAR P.Moreover, Z-DEYD-FMK, the specific inhibitor of caspase-3 , could dramatically reduce the apoptosis induced by ZST93.Taken together, ZST93 could effec tively inhibit CML cells, arrest eell cycle at G,-phase, induce cell apoptosis anrl initiate autophagy.Conclusions The potential mechanism may he related to the regulation of autophagy intiation/caspase-8/caspase-3 signaling pathway, which provides a new idea and theoretical basis for the treatment of CML.

Bisphosphonates can directly inhibit osteoclasts, which may lead to increased bone density, reduced blood flow, and osteonecrosis of the jaw. Bisphosphonate-related osteonecrosis is usually observed in the jaw bone. In this article, we report a patient with bisphosphonate-related osteonecrosis of the jaw (BRONJ) complicated with wrist scaphoid osteomyelitis. Furthermore, we introduce the pathogenesis, treatment, and prevention of BRONJ.

Background:The increasing prevalence of colorectal cancer (CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment.We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods:We conducted a multicenter,cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014.Each enrolled patient was interviewed using a structured questionnaire.All expenditure data were inflated to the 2014 Chinese Yuan (CNY;1 CNY =0.163 USD).We quantified the overall expenditure and financial burden and by subgroup (hospital type,age at diagnosis,sex,education,occupation,insurance type,household income,clinical stage,pathologic type,and therapeutic regimen).We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results:A total of 2356 patients with a mean age of 57.4 years were included,57.1％ of whom were men;13.9％ of patients had stage Ⅰ cancer;and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY,and the expenditures for stage Ⅰ,Ⅱ,Ⅲll,and Ⅳ disease were 56,099 CNY,59,952 CNY,67,292 CNY,and 82,729 CNY,respectively.Non-medical expenditure accounted for 8.3％ of the overall expenditure.The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY,which accounted for 59.9％ of their previous-year household income and caused 75.0％ of families to suffer an unmanageable financial burden.Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups (P ＜ 0.05),except for sex.Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less (all P ＜ 0.05).Conclusions:For patients in China,direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable.The financial burden varied among subgroups,especially among patients with different clinical stages of disease,which suggests that,in China,CRC screening might be cost-effective.

OBJECTIVEThis study was to investigate the condom use and its factors on sex workers in Shandong province, and to provide effective suggestions for AIDS prevention strategies and interventions.

METHODSFrom April to July in 2009, 4732 female sex workers were investigated through anonymous questionnaires from 11 cities which were selected based on the AIDS epidemic, geographic location, economic conditions in Shandong province. Serum samples were collected and antibodies were tested by ELISA and TPPA from 4641 people.

RESULTS4732 female sex workers who were 15 - 58 years old were investigated and the majority belonged to the low age group (≤ 24 years old) which accounted for 61.5% (2912/4732). Among the 4732 female sex workers, the unmarried, the divorced, or the widowed females accounted for 72.8% (3441/4725) and 72.0% (3403/4726) of them were poorly educated.42.3% (1994/4719) of them were found from other provinces. The right answers for knowledge of AIDS accounted for 45.7% (2164/4732). 80.6% (3416/4236) of these females were found to used condoms in the most recent commercial sex activity. The rate of consistently using condoms in sex activity during the last month was 58.4% (2467/4221). In this survey, 7.3% (337/4637) of investigated females had been diagnosed with sexually transmitted diseases, 30.7% (1449/4726) of them had received HIV antibody test, 70.4% (3323/4732) of these people had received the AIDS intervention services, and 3.6% (167/4668) of them had ever used drug. Multivariate logistic regression analysis showed that high education level (junior high school or lower vs senior high school or higher, adjusted OR = 0.77, 95%CI: 0.67 - 0.90), having received the HIV intervention (received vs unreceived, adjusted OR = 1.36, 95%CI: 1.17 - 1.58), antibody detection (done vs not done, adjusted OR = 1.33, 95%CI: 1.15 - 1.55), and good knowledge about AIDS (low score group vs high score group, adjusted OR = 0.37, 95%CI: 0.32 - 0.44) were independent factors that increased safe sex behavior; while using drug (drug vs not drug, adjusted OR = 0.22, 95%CI: 0.15 - 0.31) was a negative factor.

CONCLUSIONThe prevalence rate of HIV infection among female sex workers was low in Shandong province. However, the low rate of condom use and the high prevalence of self-reported STD-related symptoms suggested that more attentions should be paid to the factors of risk behaviors, and more targeted interventions are critically needed.
