The morphometric value of the anterior cranial fossa has previously been poorly documented. There is also an absence of information about the asymmetry between the two halves of this fossa. In a series of 100 Chinese adult cranial bases at random, distances from each selected osseous point to a particular plane or distances between osseous points were measured, All these points, except the frontozygomatic point only, are endocranially situated, and data on 17 variables were available for statistical analysis. As a result, the right half shows some greater sagittal values than that of the left, and the width from the frontozygomatic point to the median sagittal plane is greater on the right half than that on the left, the differences are statistically significant or highly significant. Moreover, more of the sagittal measurements on the right side Correlate significantly with the right-left measurements. Accordingly, the two halves of the anterior cranial fossa is asymmetrically designed. Problems relating to the line of demarcation between the median portion of the anterior and middle cranial fossae, as well as the possible eraniocerebrum relationship and clinical considerations are discussed.

Serum folate and vitamin B12 were measured in 171 healthy children under 14 years of age, 30 normal adults and 30 samples of normal cord blood. All the 171 children had been supplied with adequate folic acid and vitamin B12 before measurements. The results -were: 1. The lower limits of normal serum folate values were 6.1 nmol/L under 4 years, 8.4 nmol/L at age of 4-14 years and 5.0 nmol/L in adults. 2. The lower limits of normal serum vitamin B12 values were 459 pmol/L under 1 year and 107 pmol/L at age of 1 year to adults.

Objective:To investigate the impact of malnutrition diagnosed with Global Leadership Initiative on Malnutrition (GLIM) criteria on the outcomes of patients with primary gastrointestinal lymphoma (PGIL).Methods:Patients with PGIL admitted into Gansu Provincial People's Hospital from January 2014 to July 2022 were retrospectively enrolled. Nutritional risk screening was conducted using Nutritional Risk Screening 2002 (NRS 2002) scale, and malnutrition was diagnosed as per GLIM criteria. Kaplan-Meier survival analysis and multivariate Cox regression analysis were performed to investigate the effect of malnutrition as per GLIM criteria on the outcomes of PGIL patients.Results:A total of 82 patients were included. The phenotypic parameters, including body mass index (BMI), arm circumference, leg circumference and grip strength, were at significantly lower levels in the 28 malnourished patients, compared with the other non-malnourished patients. The median overall survival of patients with malnutrition as per GLIM criteria was 10 months, while that of patients without malnutrition was 41 months, showing significant differences between groups. The univariate analysis revealed that age, loss of muscle mass, tumor stage based on Lugano classification and malnutrition as per GLIM criteria were the impacting factors for survival in patients with PGIL. The multivariate analysis further demonstrated that tumor stage based on Lugano classification and malnutrition as per GLIM criteria were the independent impacting factors for survival in patients with PGIL.Conclusion:Malnutrition based on GLIM criteria is an independent risk factor for unfavorable outcomes in patients with PGIL and could be utilized as a prognostic indicator.
