Objective: To investigate the value of means of surfaces with nonhomogeneity (MSN) in esti-mating the incidence of pneumoconiosis. Methods: Based on the principal component analysis, all counties (districts) of Hebei Province, China, were divided into three categories according to the degree of pneumoconiosis hazards and the MSN model was used to estimate the incidence rate of pneumoconiosis and the number of pneu-moconiosis cases using the data of the incidence of pneumoconiosis in 2010. Results: With reference to the appli-cation requirements of the MSN model, results of the principal component analysis, and expert experience, the 172 counties (districts) in Hebei Province were divided into three categories with mild, moderate, and severe pneumoconiosis hazards. There were 74, 61, and 49 counties in the above categories, respectively, and 12, 12, and 25 counties were selected from them, respectively. The estimated number of pneumoconiosis cases in Hebei Province was 2105, and the incidence rate was 261.5 per hundred thousand, with a standard error of esti-mation of 389.9 per hundred thousand. Conclusion The MSN model provides a new thought and method for es-timating the number of pneumoconiosis cases.

Objective:To evaluate the effect of implementation of prevention from mother-to-child transmission of syphilis in Minhang district of Shanghai from 2013 to 2019.Methods:The data of 284 pregnant women with syphilis infection diagnosed by 6 midwifery medical institutions in Minhang District from January 2013 to December 2019, were collected from the database of national management information system for prevention of mother to child transmission of AIDS, syphilis and hepatitis B. Among them there were 1 case of spontaneous abortion, 4 cases of ectopic pregnancy, 42 cases of lost follow-up; the remaining 237 parturients were included in this study. The Implementation Program of prevention of mother-to-child transmission of AIDS, syphilis and hepatitis B (2015 edition) has been implemented since 2015 in Minhang district. The maternal and neonatal outcomes between the period of 2013-2015 (before program implemented, 123 cases) and the period of 2016-2019 (after program implemented, 114 cases) were compared. Results:Between 2013 and 2019, the syphilis detection rate of pregnant women remained 100.00% (100 761/100 761). The detection rates during pregnancy before and after program implementation were 95.92% (51 855/54 288) and 98.87% (45 949/46 473); the prevalence rate of syphilis was 2.93‰ (159/54 288) and 2.69‰ (125/46 473), respectively. The rate of anti-syphilis treatment was 62.60% (77/123) and 85.96% (98/114), the standard treatment rate was 20.33% (25/123) and 49.12% (56/114), the neonatal preventive treatment proportion/rate was 1/12 and 94.74% (72/76). The detection rate during pregnancy, anti-syphilis treatment rate, standardized treatment rate and neonatal preventive treatment rate after program implementation were significantly higher than those of before implementation (χ 2=988.88, 16.72, 21.81, 54.72, all P<0.01). The rate of non- Treponema pallidum antigen titer ≥ 1∶8 was 36.89% (38/103) and 17.48% (18/103), respectively in two periods; the incidence of neonatal adverse health problems was 21.49% (26/121) and 6.03% (7/116); congenital syphilis report incidence rate was 152.12/100 000 live births (83/54 562) and 23.46/100 000 live births (11/46 890), respectively. All these indicators showed a significant reduction (χ 2=9.81, 11.80, 45.10, all P<0.01). The treatment rate of pregnant women with previously diagnosed syphilis infection was 63.27% (62/98), which was lower than that of those with initially diagnosed (81.29%, 113/139) ( cOR=2.52, 95 %CI: 1.40-4.56, χ 2=9.672, P<0.01). Among whose with lost follow-up, the floating pregnant women accounted for 92.86% (39/42), 57.14% (24/42) of whom were unable to contact and 30.95% (13/42) refused to be followed up. Conclusions:After the implementation of prevention program, the rates of detection and diagnosis, standardized treatment, neonatal preventive treatment, as well as the maternal and neonatal outcomes of pregnant women with syphilis infection have been significantly improved in Minhang district of Shanghai.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.
