OBJECTIVETo measure breast basic dimension by using computer-aided projection fringe system.
METHODSA system has been developed for measuring breast basic dimension based on computer-aided projection fringe measurement and programming software. Plastic manikins breast's SN-N (sternal notch to nipple distance), N-ML (nipple to midline distance), N-N (internipple distance), MBW (base width of breast) and N-IMF (nipple to inframammary fold distance) are measured with this system. At the same time, these items are also measured with routine ruler.
RESULTSThis study indicate that the system has some merits: (1) non-touching measurement; (2) it is very rapid, the patient measured need hold his breath only 0.5 second, and all the time it takes is about 2.5 minutes; (3) the measurement's sensitivity is as high as to 0.6 mm, which meets the clinic requirement entirely; (4) the measurement's accuracy of the system is not significantly when comparing to the routine ruler's.
CONCLUSIONSComputer-aided projection fringe system for measuring breast basic dimension is feasible and advanced.

OBJECTIVE:
To explore the clinical features and genetic etiology for a neonate with Smith-Magenis syndrome (SMS).
METHODS:
Copy number variation sequencing (CNV-seq) was applied to the neonate and his parents, and the genotype-phenotype correlation was analyzed.
RESULTS:
On the second day after birth, the neonate had presented with pathological jaundice and immunodeficiency. Cranial MRI revealed ventricular enlargement and enlargement of cisterna magna. At 3 months, the infant has presented with square face, prominent forehead, deep-set eyes, hypertelorism, palpebral fissure upward and button noses. Genetic testing showed that he had carried a 2.9 Mb deletion in 17p11.2 region, seq[GRCh37] del(17)(p11.2)(chr17:16 836 379-19 880 992). The same deletion was not found in either parent.
CONCLUSION
SMS is mostly diagnosed in child and adulthood, but rarely in neonates. For neonates with SMS, the neurological and behavioral abnormalities have not been shown, but pathological jaundice, CNS abnormalities and immune deficiency may be the characteristics, which require attention of neonatal physicians.

Objective::To establish the evaluation method of Pinelliae Rhizoma (PR) resources by the analytic hierarchy process (AHP) and grey correlation degree (GCD) method, so as to explore the differences in quality components, production efficiency and appearance traits of different germplasm resources cultivated in the same environment. Method::The quality component index, efficiency index, and appearance traits index of 15 germplasm resources were measured, including moisture, total ash, extractives, total acid content, harvest index, yield, drying rate, commodity rate, decay rate and deformability of tubers. Based on AHP and grey correlation method, each indicator data was processed in a comprehensive way, its comprehensive correlation value was calculated, and different PR germplasm resources were comprehensively evaluated. Result::Based on three factors-quality composition, production efficiency and appearance traits, the comprehensive correlation value of A6 was the highest, reaching 0.749 4, which was followed by A14, A15, A7, and their comprehensive correlation values were 0.736 6, 0.726 2, 0.718 2, respectively. Therefore, the source of A6 could be used as an excellent provenance introduced to the cultivation of PR, and the provenance of A14, A15, and A7 could be used as a useful supplement. Conclusion::The method of AHP and GCD-based multi-index comprehensive evaluation is simple and comprehensive to evaluate the diversity of different PR germplasm resources, and could provide a reference for the development and utilization of resources and the screening of high-quality provenances.

Objective: To estimate the effectiveness of the primary screening strategy for liver cancer in rural areas to provide basic information for the optimization and perfection of the technical program for the early detection and treatment of liver cancer. Methods: Residents including males aged 35-64 and females aged 45-64 from 9 counties in rural China between 2013 and 2015 were selected as the target population. The participant was classified into a high-risk and non-high-risk group based on the standardized questionnaire or HBsAg, and the Chi-squared test was applied to compare differences between the two groups. The Cox proportional hazard regression models were applied to assess hazard ratio (HR) and its 95% confidence interval (CI). Results: 358 348 participants were recruited from 2013 to 2015. 1 196 individuals were identified with liver cancer until December 31, 2021, with an incidence density of 52.0/10(5) person-years. Of the participants, 54 650 were assessed as high risk (15.3%) based on the questionnaire and the status of HBsAg. The high-risk population had a higher incidence density (168.3/10(5) person-years vs 31.5/10(5) person-years) and higher risk of developing liver cancer (HR=2.98, 95% CI=2.64-3.35), compared to the non-high-risk group. Based on the questionnaire-based high-risk assessment system, 47 884 (13.4%) individuals were identified as high risk, who showed statistical differences in terms of incidence density and incidence risk, in comparison to the low-risk population (all P<0.05). HBsAg can screen out a higher proportion of high-risk individuals who are women, non-smokers, non-drinkers, and individuals without a family history of liver cancer (all P<0.05). The sensitivity analysis of the effectiveness of the whole primary screening method is stable, and high-risk individuals still had a higher risk of liver cancer. Conclusions: The primary screening method of the questionnaire-based risk assessment system and HBsAg can achieve satisfactory effectiveness. The questionnaire-based risk assessment system could identify high-risk individuals to some extent, however, it still needs to be improved to meet the actual requirements.
