Aim To investigate the effect of baicalin on cell proliferation and cell migration in human skin SCC A431 cell line. Methods The A431 cells were incu-
bated with 50 mg·L-1 baicalin. The protein level of cofilin-1 was assayed by Western blot. Cofilin-1 specific siRNA fragment was designed , synthesized and trans-
fected into A431 cells. The proliferative activity and migration ability of cells were assessed by CCK8 assay and scratch wound healing assay separately. ResultsWestern blot results showed that baicalin treatment in-hibited the cofilin-1 protein expression to 49.3% com-pared with the control group. Single baicalin treatment and cofilin-1 silencing could drease the A431 cell growth and migration. And cofilin-1 silencing signifi-
cantly enhanced the efficacy of baicalin. Conclusions Baicalin could significantly inhibit the tumor cell's growth and migration in the A431 cell line. And cofi-lin-1 might become the potential target gene to enhance the effect of anticancer drugs.

Objective:To investigate the clinical efficacy of ventriculo-peritoneal shunt (VPS) in acquired immunodeficiency syndrome (AIDS) patients with cryptococcal neoformans meningitis (CNM).Methods:Patients with AIDS and CNM who were hospitalized in Guangzhou Eighth People′s Hospital, Guangzhou Medical University from January 2015 to June 2020 were included and divided into VPS group and conventional treatment group.The data including symptoms and signs of meningitis, cerebrospinal fluid (CSF) pressure, CSF routine examination, ink staining, Cryptococcus culture and Cryptococcus culture negative time were obtained, and the clinical efficacy compared between the two groups after six and 48 weeks of treatment.Two independent samples t test or chi-square test was used for statistical analysis. Results:Among 66 AIDS patients with CNM, 26 cases in VPS group were (35.7±11.9) years, and 11 cases (42.3%) had CSF pressure> 330 mmH 2O (1 mmH 2O=0.009 8 kPa) at admission, 25 cases (96.2%) were positive for ink staining, and 20 cases (76.9%) had positive culture of Cryptococcus neoformans in CSF. There were 40 cases in the conventional treatment group with age of (38.9±12.9) years, 15 cases (37.5%) had CSF pressure>330 mmH 2O, 32 cases (80.0%) were positive for ink staining, and 31 cases (77.5%) were positive for culture of Cryptococcus neoformans in CSF. There were no significant differences of age, the proportion of patients with CSF pressure>330 mmH 2O, positive rate of ink staining, positive rate of Cryptococcus culture between the two groups ( t=-1.02, χ2=0.15, 3.49 and 0.00, respectively; all P>0.050). All patients were administrated with antifungal treatment, decreasing CSF pressure treatment, nutritional support and symptomatic treatment after admission. VPS was performed in patients with poor responses after medical conservative treatment in VPS group. At week six of treatment, the recovery rate of CSF pressure in VPS group was 57.7%(15/26), and the partial remission rate was 73.1%(19/26), which were both higher than those in conventional treatment group (31.0%(9/29) and 47.5%(19/40), respectively). The differences were both statistically significant ( χ2=3.96 and 4.22, respectively, both P<0.050). At week 48 of treatment, the recovery rate of CSF pressure in VPS group was 92.3%(24/26), the negative rate of Cryptococcus culture in CSF was 100.0%(20/20), and the complete remission rate was 46.2%(12/26), which were all higher than those in conventional treatment group (37.9%(11/29), 67.7%(21/31) and 20.0%(8/40), respectively). The differences were all statistically significant ( χ2=17.52, 8.03 and 5.10, respectively, all P<0.050). In VPS group, 22 cases were complete or partial remission, four cases were ineffective, and no death occurred, while there were 23 cases of complete or partial remission, 12 cases of ineffective and five cases of death in the conventional treatment group. The proportion of ineffective or death in the VPS group was 15.4%(4/26), which was lower than 42.5%(17/40) in the conventional treatment group. The difference was statistically significant ( χ2=5.34, P=0.021). Conclusions:VPS in AIDS patients with CNM could significantly improve the treatment outcomes, and reduce the rates of treatment failure and mortality.

This study investigates the metabolic regulatory effects of exogenous lactate on obesity mice induced by high-fat diet.We established obesity and metabolic disorder C57 mice model using a synthetic high-fat forage containing 60% fat.Some mice were fed with high-fat diet for 4 weeks to establish the model, being given 500 mg/(kg?d) lactate with ip for 4 weeks at the same time; the others were fed with high-fat diet for 8 weeks to establish the model, being given 500 mg/(kg?d) lactate 4 weeks after 4 weeks of modeling.During the trial period, the change of body weight and food intake, as well as serum glucose, lactate, triglycerides, insulin, and liver glycogen levels of both groups of mice were measured.Oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were used to assess glucose metabolism and insulin resistance in the body.At the end of the experiment, adipose tissue was dissected for weighing and histopathological examination.The expression of lipid synthesis and lipolysis genes in adipose tissue was detected by real-time PCR.The results showed that: (1) in the 4-week preventive medication trial, lactate had no significant effect on the body weight of normal and high-fat diet (HFD) mice, yet it increased the subcutaneous fat/visceral fat weight ratio; lactate could significantly reduce fasting blood glucose and liver glycogen levels in HFD mice while increasing blood lactate levels, significantly improving impaired glucose tolerance in HFD mice; lactate could improve the size and arrangement of adipocytes in the HFD group while significantly down-regulating the expression of fatty acid synthesis and lipolysis genes in adipose tissue; (2) in the 8-week treatment, both routes of lactate administration could partially reduce body weight in HFD group mice and reduce food intake, with the improvement trend for fat weight; both routes of lactate administration could significantly reduce fasting blood glucose levels in HFD mice, while significantly improving glucose and insulin tolerance, with some improvement of fasting insulin levels and insulin resistance index; both routes of lactate administration showed different degrees of improvement effect on adipocyte morphology in obese mice while significantly down-regulating lipolysis gene expression in adipose tissue.Therefore, for high-fat diet-induced obese mice with metabolic imbalance, exogenous lactate can stimulate glucose metabolism, inhibit adipose tissue lipolysis, and prevent adipocyte hypertrophy, thereby improving glucose tolerance and insulin sensitivity and reducing sugar-lipid metabolic disorder.

Objective:To investigate the differences of white matter diffusion properties between vulnerable and resistant individuals to continuous attention after sleep deprivation.Methods:According to the psychomotor vigilance test performance before and after sleep deprivation, the participants were divided into the vulnerable group( n=24) and resistant group( n=25). All participants underwent diffusion tensor imaging (DTI) scans.Tract based spatial statistics(TBSS) was used to compare fractional anisotropy(FA), mean diffusivity(MD), axial diffusivity(AD), radial diffusivity(RD) maps between the two groups.Spearman correlation analysis was conducted by SPSS 24.0 to investigate the relationships between the altered DTI metrics and PVT task performance. Results:(1) Compared with resistant group, FA value of vulnerable group decreased in the body of corpus callosum(x, y, z=-8, 9, 25, t=-7.855), right superior longitudinal fasciculus(x, y, z=-39, -7, 26, t=-6.252), bilateral anterior limb of internal capsule(x, y, z=-13, 8, 13, t=-5.235; x, y, z=12, 8, 3, t=-5.024) and right posterior thalamic radiation(x, y, z=-26, -56, 17, t=-5.469)(TFCE corrected, P<0.05, cluster size≥50 voxel). (2) Compared with resistant group, MD value of vulnerable group increased in the body of corpus callosum(x, y, z=-3, -6, 26, t=7.613), right superior longitudinal fasciculus(x, y, z=-31, -19, 38, t=5.314), bilateral anterior limb of internal capsule(x, y, z=-16, 7, 8, t=6.898; x, y, z=15, 5, 7, t=6.652), splenium of corpus callosum(x, y, z=27, -53, 17, t=6.541), and AD value increased in the right superior longitudinal fasciculus(x, y, z=-33, -19, 39, t=4.892), splenium of corpus callosum(x, y, z=-22, -49, 21, t=5.450), genu of corpus callosum(x, y, z=4, 26, 0, t=4.332), as well as RD value increased in the right superior corona radiata(x, y, z=-17, 1, 33, t=7.558), body of corpus callosum(x, y, z=4, -8, 26, t=6.699), right anterior limb of internal capsule(x, y, z=-12, 7, 3, t=5.212) (TFCE corrected, P<0.05, cluster size≥50 voxel). (3) Correlational analysis revealed that the negative correlations were found between PVT task performance and the FA value in the right superior longitudinal fasciculus( r=-0.492, P<0.001), right anterior limb of internal capsule( r=-0.510, P<0.001), right posterior thalamic radiation( r=-0.502, P<0.001) and body of corpus callosum( r=-0.464, P<0.001). The positive correlations were found between PVT task performance and the MD value in the body of corpus callosum( r=0.500, P<0.001), right superior longitudinal fasciculus( r=0.499, P<0.001), splenium of corpus callosum( r=0.462, P<0.001), right anterior limb of internal capsule( r=0.471, P<0.001), and AD value in right superior longitudinal fasciculus( r=0.643, P<0.001), as well as RD value in right superior corona radiate( r=0.498, P<0.001) (Bonferroni corrected, P<0.003). Conclusion:Differences in the microstructural characteristics of white matter fiber tracts in specific brain regions may constitute the potential neuropathological basis for the phenotypes of vulnerable and resistant individuals to continuous attention after sleep deprivation.

Objective:Based on single-center clinical results of endovascular recanalization for symptomatic non-acute internal carotid artery occlusion (ICAO), a new patient classification method is proposed to distinguish the most suitable ICAO patient subgroups for endovascular recanalization.Methods:A total of 140 patients with symptomatic non-acute ICAO accepted endovascular recanalization in Department of Cerebrovascular Intervention, He'nan Provincial People's Hospital from January 2019 to December 2021 were selected. These patients were divided into low risk group ( n=57), medium risk group ( n=54) and high risk group ( n=29) according to the occlusion segments, occlusion times, plaque features, calcification at the occlusion site and occlusion segment angulation. The immediate postoperative recanalization rate, perioperative complications, perioperative death, and prognoses 90 d after endovascular recanalization (modified Rankin scale scores of 0-2 as good prognosis) were evaluated in the 3 groups. Results:The immediate postoperative recanalization rate was 82.9% (114/140), perioperative complication rate was 11.4% (16/140), and perioperative mortality was 0.7% (1/140). The success recanalization rate decreased gradually from the low risk group to the high risk group (100%, 85.2%, and 37.9%), while the perioperative complication rate was the opposite (0%, 11.1%, and 34.5%), with significant differences ( P<0.05). Ninety d after endovascular recanalization, 109 patients had good prognosis and 27 had poor prognosis; the good prognosis rate in low risk group, medium risk group and high risk group was 98.2%, 79.6% and 34.5%, respectively, with significant differences ( P<0.05). The vascular restenosis rate in low risk group, medium risk group and high risk group was 0%, 8.7% and 18.2%, and re-occlusion rate was 0%, 6.5% and 27.2%, respectively, 90 d after endovascular recanalization, with significant differences ( P<0.05). Conclusion:Endovascular recanalization is technically feasible for patients with symptomatic non-acute ICAO, especially those met the criterions of low and medium risk groups in our study.
