Conclusion There is positively correlation between serum VEGF level and tissue VEGF expression, and between VEGF expression and clinic prognosis. Serum VEGF level may be one of important index of prognosis estimation in patients with breast cancer.

OBJECTIVE To provide evidence to establish properly protocol for medical cosmetic institutions.METHODS Through investigation to analyze the current situation and problems of disinfection and isolation in the medical cosmetic institutions.RESULTS There were 86.7% medical cosmetic institutions located in commercial buildings.And there were 33.3% institutions with improper layout of therapeutic room,sterilizing room and dressing room resulting from insufficient space or less rooms.The illumination intensity of the ultraviolet lamp and the disinfection effect of air were not coincident with standards.CONCLUSIONS There are many problems of disinfection and isolation in the medical cosmetic institutions,the disinfection is insufficient,the ultraviolet light is in wild-using,people only focus on using,but ignore irradiation dose and distance.It is very important for strictly observing Hospital Infection Management Methods,Disinfection Technology Standards and Disinfection Management Methods,and strengthening the management of disinfection and isolation in the medical cosmetic institutions.

Objective To investigate the effect of oil with medium-long-chain triacylglycerols on blood lip- id and lipoproteins in hyperlipemic patients. Methods Totally, 112 patients with hypertriglyceridemia were en- rolled and randomly divided into MLCT group (consumed oil with medium-long-chain fatty acids) and LCT group (consumed oil with long-chain fatty acids) (both 25-30 g/d for 8 weeks). Patients in both two groups were also instructed to take exercises. Height and weight were measured at baseline and 8 weeks later. Blood glucose, serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total cholesterols (TC), triglyc- erides (TG), high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein Al (ApoAl), ApoB, ApoA II , ApoC2, ApoC3, and ApoE were measured and compared. Results At the end of study, 101 subjects were included. There were 50 subjects left in LCT group and 51 subjects left in MLCT group, respectively. There was no significant difference in weight, ALT, AST, TC, and TG at baseline between two groups (P>0.05). Eight weeks later, weight, serum TG, ApoC2, and ApoC3 were significantly lower and ApoAl level was significantly higher than those at baseline in MLCT group (P < 0.05). At the end of study, the decreases in body weight and blood biochemical variables including TG, ApoB, ApoA II , ApoC2, ApoC3 were significantly much greater in MLCT groups than those in LCT group (P < 0. 05). Conclusion When the diet is reasonably controlled, oil of medium-long-chain triacylglycerols may reduce the concentration of TG and improve the levels of apolipoproteins.

Objective:To understand the genetic variation and the prevalence of H9N2 subtype avian influenza virus in Guizhou province, and to provide the scientific evidence for the prevention and control of avian influenza virus.Methods:The results of AIV detection in live poultry market(LPM) environment in Guizhou province from October 2018 to March 2019 were statistically analyzed, RNAs were extracted and sequenced from the HA genes of 13 samples of H9N2 positive screened by real-time PCR. Then the homology, the genetic evolution and the mutations of important amino acid were analyzed by bioinformation softwares. Results:The positive rate of AIV was 52.2% and the positive rate of H9N2 was 83.7% in LPM environment. The homology between nucleotides of the HA gene of 21 strains ranged from 91.6% to 100.0%, and the homology between amino acids of the HA gene ranged from 91.0% to 100.0%. All strains belonged to Y280 sublineage and G57 genotype. Key sites analysis showed that they had a common motif PSRSSRGLF and LSRSSRGLF at the cleavage site, which indicated that they were lentogenic and low pathogenic strains. Mutations H191N, E198T/A and Q234L at the receptor binding sites in the HA was found in 21 strains, while indicated the viruses had the potential to bind human-like receptor. The analysis results of glycosylation motifs showed that all 21 strains had 7 glycosylation sites, but had a site deletion at amino acid site 218 and an addition at 313.There was no significant mutation in the key site compared with the human infected strains. Conclusions:The detection rate of AIV in LPM environment in Guizhou province was high, and the pollution was very serious, and H9N2 subtype is the main subtype, All H9N2 subtype AIVs belonged to Y280 sublineage and G57 genotype, and they were low pathogenic avian influenza viruses in Guizhou province, but the genetic gap were widening and mutations of key amino acid site might enhance susceptibility and pathogenicity to human beings. Hence, It is necessary to strengthen the surveillance of molecular characteristic variation of H9N2 subtype AIV.

Objective To investigate the expression and significance of FBXW7 and ENO1 in ovarian serous adenocarcinoma of different grades. Methods Immunohistochemistry was used to study the expression of FBXW7 and ENO1 in 60 cases of ovarian serous adenocarcinoma. The relationship between FBXW7 and ENO1 proteins and the prognosis of ovarian serous adenocarcinoma was analyzed. Results The positive rate of FBXW7 expression was 22. 5％ ( 9/40) in 40 cases of ovarian high grade adenocarcinoma and 10 cases in 15 cases of normal oviduct. The positive rate of FBXW7 expression was 66. 7％ ( 10/15) ,and the difference was statistically significant ( P=0. 003) . The expression of FBXW7 in 20 cases of low grade adenocarcinoma was 5 cases,and the positive rate was 25. 0％( 5/20) . In 15 cases of normal ovarian tissue,9 cases were positive,and the positive rate was 60. 0％( 9/15) . The difference was statistically significant ( P=0. 04) . The expression of ENO1 protein was 27 in 40 cases of high grade adenocarcinoma,and the positive rate of expression was 67. 5％( 27/40) . 5 cases were positive in 15 normal fallopian tubes, and the positive rate was 33. 3％( 5/15 ) . The difference was statistically significant ( P = 0. 024 ) . The expression of ENO1 protein was 15 in 20 cases of low grade adenocarcinoma,and the positive rate of expression was 75. 0％( 15/20) . In 15 cases of normal ovarian tissue,4 cases were positive, and the positive rate was 26. 7％( 4/15 ) . The difference was statistically significant ( P=0. 006) . There was no correlation between the low expression of FBXW7 and the high expression of ENO1 in high grade ovarian adenocarcinoma ( P= 0. 199 ) , but there was a significant correlation between the low expression of FBXW7 and the high expression of ENO1 in low grade ovarian adenocarcinoma ( P<0. 05) . In low grade serous adenocarcinoma,the 5-year survival rates were 44. 4％ and 32. 1％ respectively,with no significant difference ( P = 0. 052 ) . In ovarian high-grade serous adenocarcinoma, the 5-year survival rates of high-expression group and low-expression group were 20. 0％ and 7. 7％, respectively, with no significant difference ( P=0. 097) . In low grade ovarian serous adenocarcinoma,the 5-year survival rate was 7. 4％ in high expression group and 50. 0％ in low expression group ( P=0. 023) . The 5-year survival rates of ENO1 in high-grade serous adenocarcinoma were 0％ and 40. 0％ in high-expression group and low-expression group respectively ( P=0. 001) . Conclusion The low expression of FBXW7 in ovarian adenocarcinoma suggests that FBXW7 may be a tumor suppressor gene in ovarian serous adenocarcinoma, and ENO1 may be an oncogene in ovarian adenocarcinoma. The high expression of FBXW7 in serous adenocarcinoma indicates that ENO1 may be an oncogene,and the survival rate of FBXW7 in serous adenocarcinoma is higher than that in low expression group. The survival rate of the high-expression group was lower than that of the low-expression group. Therefore, they may become a new diagnostic index and therapeutic target for ovarian serous adenocarcinoma.

【Objective】 To explore the feasibility and accuracy of neutrophil-to-lymphocyte ratio (NLR) in the prediction of testicular torsion (TT) in children with acute scrotal pain. 【Methods】 A retrospective case-control study was performed on 158 pediatric patients with ultrasound suspicion of TT who underwent surgical testicular examination during Jan.2017 and Jan.2024.The patients were divided into TT group and non-TT group.Clinical data and laboratory data at admission were analyzed.Sensitivity and specificity of NLR to TT were determined with the area under the curve (AUC) represented on the receiver operating characteristic (ROC) curves. 【Results】 There were with no statistically significant differences in clinical data between the two groups (P>0.05).The NLR was significantly higher in the TT group than in the non-TT group [ (4.82±2.37) vs.(2.85±0.75), P<0.05] .The optimal cut-off value of TT predicted by NLR was 2.07, the AUC was 0.809 (95%CI:0.709-0.909), and the sensitivity and specificity were 97.9% and 93.3%, respectively, which were significantly higher than other factors. 【Conclusion】 For suspicious ultrasound diagnosis of pediatric acute scrotal pain cases, NLR can be used to predict the possibility of TT and may help to evaluate the urgent surgical treatment in these patients.

Objective:To analyze the molecular evolution characteristics of HA and NA genes of influenza B/Yamagata (BY) and influenza B/Victoria (BV) lineage viruses in Guizhou Province, aiming to provide reference for scientific prevention and control of influenza. Methods:The prevalence of various types of influenza viruses in Guizhou Province from 2017 to 2021 was analyzed. The nucleic acid of influenza B viruses was extracted, and then the HA and NA genes were amplified by RT-PCR. Fourteen strains were sequenced and the sequences of 83 strains were obtained from GISAID. Homologies between the 97 influenza B viruses as well as the phylogenetic characteristics and amino acid site variations were analyzed. Results:Influenza A, BY and BV lineage viruses co-circulated in Guizhou Province and BV lineage was the predominant type. The homologies of HA and NA genes were 98.7%-99.4% and 98.4%-99.6% between BY lineage viruses and the reference vaccine strain B/PHUKET/3073/2013. BV lineage viruses shared 98.3%-99.3% and 98.9%-99.6% homologies with the reference vaccine strain B/Colorado/06/2017. The BY lineage strains in Guizhou Province mainly belonged to Y3 genetic group with HA gene in two branches of Y3-H1-2 and NA gene in three branches of Y3-N1-3. Three reassortant strains were found in Y3 clade. The isolated BV lineage strains mainly belonged to V1A-2 genetic group with HA gene in four branches of V1A-2 H1-4 and NA gene in five branches of V1A-2 N1-5. Twenty reassortant strains were found in V1A-2 clade and no inter-lineage reassortants were found. Analysis of variations at key amino acid sites showed that there was no mutation at epitopes in Y3 genetic group. However, there were point mutations at four main epitopes and a shift mutation in 190 helix in V1A-2 genetic group. There was no mutation in drug resistance sites. Conclusions:Various types of influenza viruses circulated in Guizhou Province. The homology between influenza B viruses and vaccine strains was decreasing. Different branches of HA and NA genes had been evolved and various forms of mutations were detected in the sequences. Intra-lineage reassortant strains and new varieties emerged. Surveillance of influenza B viruses should be strengthened.
