Cerebral palsy (CP) is the most common activity limitition of children, their movement and posture impairments persist throughout whole life.In recent years, CP has been significantly increasing with the improved survival rate of newborns.This may lead to a great burden and costs to both the family and the society.A variety of risk factors have been proposed to be associated with CP.However, recent abroad researches indicate that genetic factors may predispose to CP of newborns and initial results of related researches infer that several susceptibility genes may contribute to CP's development, masqueraders have a great impact on CP's clinical symptoms.Now, the recent publications related to virulence genes and masqueraders of CP are reviewed.

Metastasis is the essential character of biological behaviors in malignancies,which is also the main reason for the death of patients with tumor. So it is very important to research the metastasis for the pre-vention and treatment of carcinomas. Rectal cancer is one of the most common gastrointestinal cancer,and its prognosis is bad. lymphatic metastasis is one important factor in the determination of colon cancer' s progno-sis. More than 50% patients are found lymphatic metastasis when taking operation. The ralationship of lym-phatic metastasis and prognosis is more important than the original tumor's invasiving. So it is meaningful to study the mechanism of tumor metastasis, and to provide a scientific approach to the prediction of tumor me-tastasis, the precise assessment of prognosis and the treatment of tumor metastasis.

Objective:To investigate the influencing factors of ultrasonic missed diagnosis of kidney neoplasm.Methods:The clinical data of 2 033 patients pathologically diagnosed with kidney neoplasm after operation and with complete medical record in Shanxi Province Cancer Hospital from January 2013 to October 2021 were retrospectively analyzed. Preoperative ultrasound diagnosis, clinical data, CT/magnetic resonance imaging (MRI) were analyzed, and ultrasound missed diagnosis rate was calculated. Chi-square test and multivariate logistic regression were used to analyze the influencing factors of ultrasonic missed diagnosis of kidney neoplasm mainly based on the anatomic characteristics of neoplasm.Results:The ultrasonic missed diagnosis rate of kidney neoplasm was 1.87% (38/2 033), among which the ultrasonic missed diagnosis rate of renal parenchymal neoplasm was 1.33% (25/1 874) and the ultrasonic missed diagnosis rate of renal pelvis neoplasm was 8.18% (13/159). The results of multivariate logistic regression analysis showed that the patients' body mass index (BMI) ≥ 24 kg/m 2 ( OR = 2.805, 95% CI 1.030-7.641), the small lesion ( OR = 0.425, 95% CI 0.293-0.617), the lesion located on the left kidney ( OR = 0.307, 95% CI 0.113-0.834), the lesion located on the body ( OR = 0.344, 95% CI 0.124-0.956 compared to lesions in the upper pole of the kidney; OR = 0.239, 95% CI 0.069-0.834 compared to lesions in the lower pole of the kidney) and the lesion located on the dorsal side ( OR = 0.409, 95% CI 0.172-0.970) were independent influencing factors for ultrasound missed diagnosis of renal parenchymal neoplasms (all P < 0.05). Patients with BMI ≥ 24 kg/m 2 ( OR = 10.464, 95% CI 1.042-105.087), concurrent ureteral or (and) bladder urothelial carcinoma ( OR = 32.937, 95% CI 4.017-270.063), and small lesion size ( OR = 0.216, 95% CI 0.081-0.577) were independent influencing factors for ultrasound missed diagnosis of renal pelvis neoplasms (all P < 0.05). Conclusions:Obesity, small focus, focus on the left kidney, focus on the body, and focus on the back may be the main reasons for ultrasonic missed diagnosis of renal parenchymal neoplasms. Obesity, concurrent ureteral or/and bladder urothelial carcinoma and small lesions may be the main reasons for ultrasonic missed diagnosis of renal pelvis neoplasms.

Objective To identify species of common sarcosaprophagous flies based on digital image analysis of veins, in order to provide new idea for fast and accurate species identification of sarcosaprophagous flies in forensic entomology. Methods Random trapping of 226 male and female sarcosaprophagous flies that comprised of 7 common species, including Sarcophaga peregrina, Parasarcophaga ruficornis, Sarcophaga dux, Seniorwhitea reciproca, Bercaea cruentata, Aldrichina grahami, and Synthesiomysia nudiseta with carrion in the field was conducted. The 17 landmarks on the right wing of each fly were digitally processed and the images were analyzed. The effects of allometry were evaluated using a permutation test. Wing shape variations among 7 sarcosaprophagous fly species and female species was analyzed using canonical variate analysis (CVA). Additionally, cross-validation test was used to evaluate the reliability of classification. Results Among 7 sarcosaprophagous fly species and female species, the effect of allometry had statistical significance (P<0.05). The CVA results showed that among 7 sarcosaprophagous fly species and female species, differences in the wing shape were significant, and the first two canonical variates accounted for 82.9% and 84.1% of the total variation of vein shape. Vein digital image analysis can be used to separate the 7 common sarcosaprophagous flies, with an overall species identification accuracy of 81.2%-100.0%, and with a species identification accuracy of 75.0%-100.0% to distinguish the female flies of the 7 sarcosaprophagous flies species. Conclusion Vein digital image analysis is a relatively convenient and reliable method for identification of insect species, which can be used for species identification of common sarcosaprophagous flies.
