Objective: To investigate the mortality and life loss of malignant tumors among residents in Xicheng District, Beijing from 2014 to 2021, so as to provide the evidence for formulating the control strategy for malignant tumors. Methods: Data pertaining to dead cases of malignant tumors in Xicheng District from 2014 to 2021 were collected from Beijing Integrated and Analysis Platform for Health and Disease Prevention Monitoring Information Resources. The crude mortality, standardized mortality, years of potential life lost (YPLL), years of potential life lost rate (YPLLR), rate of standardized years of potential life lost (SYPLLR), average years of life lost (AYLL) and annual percent change (APC) of malignant tumors were measured to analyze the trends in mortality of malignant tumors and life loss. Results: A total of 23 202 residents died from malignant tumors in Xicheng District from 2014 to 2021, and the crude and standardized mortality rates of malignant tumors were 198.09/105 and 101.46/105, respectively. The standardized mortality of malignant tumors was 117.36/105 among men and 85.97/105 among women. The standard mortality of malignant tumors appeared a tendency towards a decline among all cases (APC=-1.515%, t=-4.289, P=0.005) and women (APC=-1.629%, t=-3.046, P=0.023), and the crude mortality of malignant tumors appeared a tendency towards a rise with age (χ2trend=49.324, P<0.001). The five most deadly malignant tumors included lung cancer, colorectal cancer, liver cancer, stomach cancer and pancreatic cancer, and lung cancer, liver cancer and colorectal cancer were the three malignant tumors with the three highest life loss, with YPLL of 18 054 person-years, 9 446 person-years and 8 179 person-years, respectively. Leukemia had the highest AYLL (15.95 years per person). Conclusions The standardized mortality of malignant tumors appeared a tendency towards a decline among residents in Xicheng District from 2014 to 2021, and men and the elderly people were at high risk of malignant tumors. Lung cancer, colorectal cancer and liver cancer were leading causes of death, leukemia was the major cause of life loss.

Objective To identify the GNAS gene mutation resulting in pseudohypoparathyroidism type Ⅰa (PHP-Ⅰa) in one patient. Methods The clinical data of a patient with pseudohypoparathyroidism type Ⅰa was retrospectively analyzed. All the 13 exons of GNAS were sequenced using Sanger method for the patient and the parents. The distribution of suspected causal mutation was screened in 478 healthy controls. To clarify the origin of the mutation, we performed targeted high-depth sequencing of GNAS exon harboring the mutation for the patient and the parents. Results The clinical data of the patient with the laboratory results of hypocalcaemia, hyperphosphataemia, elevated serum PTH, together with the features of AHO, conformed to the characterization of PHP-Ⅰa. The sequencing of GNAS exons identified a missense mutation (c.479G>C, p.R160P) located at exon 6 in the patient, which was absent in DNA of the parents. The mutation was not reported previously and was not found in the 478 healthy controls. We obtained about 8000-fold coverage from high-depth sequencing of DNA from peripheral blood of the patient and the parents. The disease-associated allele C identified in the patient was not observed in the parents. The number of reads with G allele (3984 reads) was roughly equal to that of C allele (4019 reads) from the targeted reanalysis of DNA of the patient. The results from high-depth sequencing indicated a de novo mutation in maternal germ cells. Conclusions We identified a new GNAS gene mutation (c.479G>C, p.R160P) caused PHP-Ia in a patient. Our results suggested the mutation was a maternal germline de novo mutation.

OBJECTIVETo investigate the clinical effects of bone setting manipulation on simplified operation and swelling reduction in treating calcaneal fractures.

METHODSFrom December 2005 to November 2010, 42 patients with calcaneal were reviewed, including 25 males and 17 females, ranging in age from 18 to 74 years, with an average of 41.4 years. Twenty patients had fractures in the left and 22 in the right. Twenty-three patients were treated with anatomical plate fixation, 19 patients were treated with Kirchners wires or cannulated screws fixation. The average period of swelling in soft tissue, joint function and complications were evaluated.

RESULTSForty-two patients were followed up, and the duration ranged from 3 to 18 months, with a mean of 8.3 months. The pain was markedly relieved at the next day after reduction, and the swelling was relieved in 3 to 5 days. The operative was simplified and the average operative time was 90 minutes. The swelling was relieved in 4 to 7 days after the operation, and the necrosis of skin was not found. The average postoperatively Böhler angle was (31 +/- 3.2) degrees. Gissane angle was (112 +/- 5.3) degrees. Calcaneal width was (30.2 +/- 0.89) mm. According to Maryland foot function score system, 16 patients got an excellent result, 18 good, 6 fair and 2 bad.

CONCLUSIONThe operation is simplified, and skin complications decrease, as well as the detumescence period is shortened.

OBJECTIVETo explore the incidence of sudden cardiac death (SCD) of urban residents in Beijing.

METHODSA community based epidemiology survey was performed on the residents of 4 communities in the Xicheng and Haidian districts in Beijing from October 2008 to September 2009. Data on the total population, age, gender and vital status were monitored, and incidence of SCD as well as related information were collected from the household administrative workers, the family members of the deceased, the hospital personnel and the witnesses.

RESULTS479 521 subjects (244 000 men and 235 521 women) were monitored, a total of 1 285 (642 men and 643 women) all cause death occurred during the study period and 184 (86 men and 98 women) deaths were identified as SCD. The incidence of SCD was 35.2 (95%CI 27.8-42.7) per 100 000 per year for men and 41.6 (95%CI 33.4-49.8) per 100 000 per year for women. SCD accounted for 13.4% mortality in men and 15.2% mortality in women. There were 171 (91.0%) SCD cases in residents over 55 years of age. The incidence of SCD for the age group 0-24, 25-34, 35-44, 45-54, 55-64, 65-74 and 75 years and over was 5.6, 4.6, 3.0, 9.8, 78.4, 88.4, and 272.8 per 100 000 per year for men, and 1.6, 0, 3.2, 0, 21.1, 84.2 and 470.0 per 100 000 per year for women, respectively. The proportion of the cases that have at least one cardiovascular disease history was 57.0% (49/86) for men and 60.2% (59/98) for women. The cases that occurred at home, on the way to hospital, in the hospital emergency room, in the hospital ward and other places account for 53.3% (98 cases), 12.2% (22 cases), 9.2% (17 cases), 12.5% (23 cases) and 13.0% (24 cases) of the 184 SCD cases, respectively.

CONCLUSIONSCD is a great threat to the urban residents in Beijing. Most SCD cases occurred at home on residents over 55 years of age. More than half SCD residents have at least one cardiovascular disease. It is important to take preventive measures in the urban residents over 55 years old and with history of cardiovascular disease.

OBJECTIVE To evaluate the effectiveness， safety， economy， innovation， suitability and accessibility of recombinant Mycobacterium tuberculosis fusion protein （EC）， and to provide evidence for selecting skin detection methods for tuberculosis infection diagnosis and auxiliary diagnosis of tuberculosis. METHODS The effectiveness and safety of EC compared with purified protein derivative of tuberculin （TB-PPD） were analyzed by the method of systematic review. Cost minimization analysis， cost-effectiveness analysis and cost-utility analysis were used to evaluate the short-term economy of EC compared with TB-PPD， and cost-utility analysis was used to evaluate the long-term economy. The evaluation dimensions of innovation， suitability and accessibility were determined by systematic review and improved Delphi expert consultation， and the comprehensive score of EC and TB-PPD in each dimension were calculated by the weight of each indicator. RESULTS The scores of effectiveness， safety， economy， innovation and suitability of EC were all higher than those of TB-PPD. The affordability scores of the two drugs were consistent， while the availability score of EC was lower than those of TB-PPD. After considering dimensions and index weight， the scores of effectiveness， safety， economy， innovation， suitability， accessibility and the comprehensive score of EC were all higher than those of TB-PPD. CONCLUSIONS Compared with TB-PPD， EC performs better in all dimensions of effectiveness， safety， economy， innovation， suitability and accessibility. However， it is worth noting that EC should further improve its availability in the dimension of accessibility.
