Objective To explore the application disturbance coefficient (DC) value of noninvasive brain edema monitoring in patients after traumatic brain injury.Methods A total of 54 cerebral injury patients were performed by non-invasive brain edema monitoring from June to November 2016.The essential information,DC,intracranial pressure (ICP),and 6-month-later glasgow outcome score (GOS) were collected.Results DC was negatively correlated with ICP (r=-0.779 5,P＜0.01),and it was positively correlated with glasgow coma scale (GCS) and GOS (r=0.667 5,P＜0.01;r=0.630 6,P＜0.01).The mean of DC with good prognosis patients was 106.99±4.09,and that of the poor prognosis patients was85.26±4.45,the difference was statistically significant (P＜0.05).Conclusion DC has a good clinical application value.

Objective To provide evidence-based references for the prevention of surgical site infection(SSI)by sum-marizing the best evidence for the prevention of SSI in adult inpatients.Methods The'6S'evidence resource pyramid model was used to systematically search the related evidence in domestic and foreign databases,guideline websites,and academic socie-ty websites from the inception of the database to September 30,2023.Four researchers evaluated the quality of the included guidelines,and two researchers independently evaluated the quality of other types of literature and rated the level of evidence.Results A total of 12 articles were included,including 6 clinical decision making and 6 clinical guidelines.Thirty best items of the evidence were summarized from 7 aspects:diagnosis,clinical symptoms,influencing factors,patient prevention strategies,preventive strategies for medical staff,intraoperative and postoperative treatment,and consultation and education.Conclusion Clinical staff should develop a standardized management plan for infection prevention based on corresponding evidence to reduce the incidence of SSI instead of taking a single measurement.Moreover,they need to formulate a standardized work process for preventing SSI based on the clinical practice and patients'preference.

To explore the proportion for facial aesthetics that may be recognized by the potential group who will do plastic surgery in the future. 
 Methods: We measured the celebrity photos, who were born before 1980 recognizable by the people over 40 years old or by high school students. The proportions for facial aesthetics recognizable by these two generations were obtained and compared. 
 Results: Compared the new generation of male celebrities with the older generation of male celebrities, the difference was statistically significant by the independent samples t test (t=-2.502, P<0.05), while other ratios were not statistically significant (P>0.05). Compared the new generation of female celebrities with the older generation of female celebrities, the difference was statistically significant by the independent samples t test. The ratios between inter-canthic diameter and eyeslit breadth, mouth breadth and eyeslit breadth, stirnhohe and 1/3 of the physiognomic facial height, nasal height and 1/3 of the physiognomic facial height were significantly different (P<0.05), while other ratios were not significantly different (P>0.05).
 Conclusion: The young new generation loves more larger eyeslit breadth for men, while a larger eyeslit breadth, smaller bizygomatic breadth and sharper chin for women.

OBJECTIVETo characterize the mutation spectrum of phenylalanine hydroxylase (PAH) gene and perform prenatal diagnosis for families with classical phenylketonuria.

METHODSBy stratified sequencing, mutations were detected in the exons and flaking introns of PAH gene of 44 families with classical phenylketonuria. 47 fetuses were diagnosed by combined sequencing with linkage analysis of three common short tandem repeats (STR) (PAH-STR, PAH-26 and PAH-32) in the PAH gene.

RESULTSThirty-one types of mutations were identified. A total of 84 mutations were identified in 88 alleles (95.45%), in which the most common mutation have been R243Q (21.59%), EX6-96A>G (6.82%), IVS4-1G>A (5.86%) and IVS7+2T>A (5.86%). Most mutations were found in exons 3, 5, 6, 7, 11 and 12. The polymorphism information content (PIC) of these three STR markers was 0.71 (PAH-STR), 0.48 (PAH-26) and 0.40 (PAH-32), respectively. Prenatal diagnosis was performed successfully with the combined method in 47 fetuses of 44 classical phenylketonuria families. Among them, 11 (23.4%) were diagnosed as affected, 24 (51.1%) as carriers, and 12 (25.5%) as unaffected.

CONCLUSIONPrenatal diagnosis can be achieved efficiently and accurately by stratified sequencing of PAH gene and linkage analysis of STR for classical phenylketonuria families.

To explore the role of progesterone in the pathogenesis and development of hemangioma in nude mice.
 Methods: The hemangioma model was established. Progesterone was injected intramuscularly at different doses (0.2, 0.4, and 0.8 mg/d) for one week. Camellia oil (0.4 mL/d) was injected intramuscularly as control. The size of hemangioma was observed dynamically. The subcutaneous implants were harvested on the 14th and 28th days. The expression of vascular endothelial growth factor in the tumor tissues were evaluated using immunohistochemistry and microvessel density (MVD) was counted under the microscope.
 Results: On the 14th day, the expression of vascular endothelial growth factor (P<0.01 and P<0.05, respectively) was higher, the volume of tumors (All P<0.01) and MVD (All P<0.01) were greater in the high-dose progesterone group than those in the control and low-dose progesterone group. On the 28th day, there was no significant difference in the volume of tumors among 4 groups (P>0.05). The expression of vascular endothelial growth factor (P<0.01) was lower, and MVD (All P<0.05) were less in the middle-dose and high-dose progesterone group than those in the control and low-dose progesterone group.
 Conclusion: Progesterone promotes angiogenesis via upregulation of vascular endothelial growth factor expression, promotion of hemangiomas proliferation, suggesting that excessive progesterone supplementation may be one of the initial factors for early hemangioma formation.
