Objective To investigate the effects of berberine on tumor-associated macrophages (TAM)and the expression of cyclooxygenase-2 (COX-2)of intestinal polyps in Apc(Min/+) mice.Methods A total of 20 Apc(Min/+) mice,four weeks old,were equally divided into the control group and the berberine group,10 in each group.The mice of the control group drank plain water,while the mice of berberine group drank water with 0.1 % berberine.After 12 weeks,all the mice were sacrificed.The intestine and colon were isolated,and the numbers of polyps were counted.The expression of F4/80,inducible nitric oxide synthase-2 (iNOS),macrophage mannose receptor (MR)and COX-2 was detected by immunohisto-chemistry method.The relative expression of COX-2 at protein level was measured by Western blotting. The t test was performed for comparison between two independent groups.Results The total number of intestinal polyps,the number of small intestinal polyps and the number of colon polyps of the berberine group (11 .50±2.05 ,10.50±1 .77 and 1 .00±0.46,respectively)were all less than those of the control group (30.63±1 .69,28.00±2.00 and 2.63±0.74,respectively),and the differences were statistically significant (t=16.727,16.952 and 3.162,P =0.001 ,0.001 and 0.010,respectively).The percentage of F4/80 positive cells in the stroma of polyps of the berberine group ((17.40 ±4.23 )%)was less than that of the control group ((31 .24±6.34)%),and the difference was statistically significant (t =5 .327, P =0.043).The percentage of iNOS positive cells in the stroma of polyps of the berberine group ((7.43± 1 .78 )%) was higher than that of the control group ((2.72±0.68)%), and the difference was statistically significant (t=7.335 ,P =0.004).The percentage of MR positive cells in stroma of polyps of the berberine group ((19.52±1 .54)%)was less than that of the control group ((12.63±0.68)%),and the difference was statistically significant (t=5 .634,P =0.016).The percentage of COX-2 positive cells in stroma of polyps of berberine group ((3.38 ± 0.51 )%)was less than that of the control group ((7.60±0.57 )%),and the difference was statistically significant (t = 7.234,P = 0.001 ).The relative expression of COX-2 at protein level of polyps of the berberine group was lower than that of the control group. Conclusion Berberine may take the role in inhibiting the growth of intestinal polyps in Apc(Min/+) mice through interfering the differentiation of TAM in polyps and suppression the expression of COX-2.

OBJECTIVE: To establish a supplementary diagnostic indicator (infrared radiant intensity) in tongue diagnosis of traditional Chinese medicine (TCM) in patients with hyperplasia of mammary glands through correlation analysis of infrared radiant intensity between hyperplastic breast tissue and tongue surface. METHODS: Infrared radiant intensity of the hyperplastic breast tissue and different points on tongue surface in 20 cases of hyperplasia of mammary glands with liver-energy stagnation and phlegm retention syndrome and 16 cases of hyperplasia of mammary glands with irregular thoroughfare and conception vessels syndrome were measured with external infrared spectrometer PHE-201 made by Shanghai Institute of Technical Physics. Correlation of infrared radiant intensity between the hyperplastic breast tissue and the different points on tongue surface was assessed by using bivariate correlation analysis. RESULTS: The results showed that the numbers of positive correlated wave bands of infrared radiant intensity between the hyperplastic breast tissue and different detected points on tongue surface in the patients with liver-energy stagnation and phlegm retention syndrome and irregular thoroughfare and conception vessels syndrome were 127 (83.55%) and 71 (46.71%), respectively. Infrared radiant intensity between the hyperplastic breast tissue and the tongue surface had a positive correlation. CONCLUSION: Infrared radiant intensity can be used as one of supplementary diagnostic indicators in TCM tongue diagnosis of hyperplasia of mammary glands.

Objective:
To identify confounding factors associated with dental caries prevention, as the basis for the development of subsequent health management plan for dental caries prevention in young children.
Methods:
From June to September 2019, a questionnaire survey was conducted among parents of young children enrolled in five kindergartens in the district of Shanggang Steel Community, Pudong New District, Shanghai, using the convenience sampling method. The survey included basic demographic characteristics on parents and children, as well as information factor, motivation factor, behavioral skills, and caries prevention behavior.
Results:
Among 718 parents surveyed, the median information factor score was 8 (7, 9), the median personal motivation factor score was 20 (19, 20), the median social motivation factor score was 9 (8, 10), the median behavioral skills score was 25 (24, 25), and the median caries prevention behavior score was 7 (5, 8). Motivation factor was positively associated with behavioral skills, both information factor and behavioral skills were positively associated with dental caries prevention (P<0.05). Personal motivation factor had a direct influence factor of 0.80 on behavioral skills and an indirect influence factor of 0.15 on dental caries prevention behavior; behavioral skills and information factor had a direct influence factor of 0.19 and 0.26 respectively on dental caries prevention.
Conclusion
The finding suggest that in addition to oral hygiene information and education for parents of young children, mental support should be a key component of any community-based dental caries prevention program.

The National Medical Products Administration has authorized sodium oligomannate for treating mild-to-moderate Alzheimer's disease.In this study,an LC-MS/MS method was developed and validated to quantitate sodium oligomannate in different biomatrices.The plasma pharmacokinetics,tissue distri-bution,and excretion of sodium oligomannate in Sprague-Dawley rats and beagle dogs were system-atically investigated.Despite its complicated structural composition,the absorption,distribution,metabolism,and excretion profiles of the oligosaccharides in sodium oligomannate of different sizes and terminal derivatives were indiscriminate.Sodium oligomannate mainly crossed the gastrointestinal epithelium through paracellular transport following oral administration,with very low oral bioavail-ability in rats(0.6%-1.6%)and dogs(4.5%-9.3%).Absorbed sodium oligomannate mainly resided in circulating body fluids in free form with minimal distribution into erythrocytes and major tissues.So-dium oligomannate could penetrate the blood-cerebrospinal fluid(CSF)barrier of rats,showing a con-stant area under the concentration-time curve ratio(CSF/plasma)of approximately 5%.The cumulative urinary excretion of sodium oligomannate was commensurate with its oral bioavailability,supporting that excretion was predominantly renal,whereas no obvious biliary secretion was observed following a single oral dose to bile duct-cannulated rats.Moreover,only 33.7%(male)and 26.3%(female)of the oral dose were recovered in the rat excreta within 96 h following a single oral administration,suggesting that the intestinal flora may have ingested a portion of unabsorbed sodium oligomannate as a nutrient.

Objective To compare the applied signification of optical and ultrasonic biometry in observing the axial length of eyes with vitreous hemorrhage and retinal detachment. Methods This is a prospective clinical study. We randomly selected 57 cases (57 eyes) with vitreous hemorrhage and (or) retinal detachment from May 1, 2016 to May 31. Patients had not been performed eye surgery, also denied the history of ocular trauma and excluded other eye diseases. 25 eyes with vitreous hemorrhage, 24 eyes with retinal detachment, 8 eyes complicated with vitreous and retinal detachment hemorrhage. At 24 hours before surgery, we measured axial length using the Lenstar LS 900, immersion B-ultrasound (IB) and immersion A-ultrasound (IA). The differences between three methods were assessed with paired sample t-test. Results IB and IA data was collected from all 57 eyes, there was no statistical significance between measurements of IB and IA (P > 0.05). In the eyes with serious refractive medium opacity (36 eyes), the results showed no statistical significance difference between measurements of IB and IA (P > 0.05). The measurements of three groups can be obtained from the rest eyes (21 eyes): significant statistical difference of the measurements between IB and Lenstar was detected[(24.057±1.441)mm vs(23.470±1.775)mm],(t=3.099, P < 0.05) same results between IA and Lenstar was obtained [(23.962±1.443) mm vs (23.470±1.775) mm], difference was statistically significant (t=2.643, P < 0.05). But the measurements showed no statistical significance difference between the measurements of IB and IA (P > 0.05). Conclusions In the eyes with vitreous hemorrhage and (or) retinal detachment, the measurements of axial length could not be achieved or existed deviations on account of refractive medium opacity when using optical biometry. Under such circumstances, we should choose IA or IB as the optimization method to obtain measurements, in order to get much more accurate results.
