Objective To establish a method for the determination of Fe, Cu, Zn, Mn in the pollen by flame atomic absorption spectrometry(FAAS).Methods Wet digestion-flame atomic absorption spectrophotometry was used to determine the content of Fe, Cu, Zn, Mn in the pollen.Results In the selected experimental conditions, the recovery rates of these elements were 98.5%-103.0% and the coefficient of variation was 1.13%-2.36%.The detection limits were 0.40 ?g/L for Fe, 0.08 ?g/L for Cu, 0.20 ?g/L for Zn, 0.14 ?g/L for Mn.The linear range was 0.00-2.00 mg/L.Conclusion FAAS is simple, fast, accurate for the determination of Fe, Cu, Zn, Mn in the pollen.

Objective:To study the effect and underlying mechanism of sulfur-fumigation and water-soaking on total ash of Di-oscoreae Rhizoma, find the key factor( s) affecting the total ash of Dioscoreae Rhizoma, and explore the rationality of ash limits of Di-oscoreae Rhizoma described in Chinese Pharmacopoeia. Methods:Dioscoreae Rhizoma was respectively dealt with sulfur-fumigation and water-soaking. The changes in total ash content of Dioscoreae Rhizoma was detected by the ash determination methods for total ash and SO2 described in the pharmacopoeia, and then the ash content change of inorganic salts was used to study the mechanism. Results:Sulfur-fumigation could slightly reduce the total ash content of Dioscoreae Rhizoma, while significantly reduce the ash content of calcium oxalate and calcium sulfate with the reduction degree of 7. 20% and 9. 90%, respectively. Calcium phosphate and calcium chloride were slightly affected by sulfur-fumigation, and the results indicated that the effect of sulfur-fumigation on ash content was mainly real-ized by increasing the decomposition rate of calcium oxalate and calcium sulfate. Water-soaking could decline the ash content of Di-oscoreae Rhizoma, and the phenomenon was common in the rhizome medicinal materials. The influence of water-soaking on total ash was more significant than that of sulfur fumigation. Conclusion:Sulfur-fumigation can reduce the total ash content of Dioscoreae Rhizo-ma by increasing the decomposition rate of calcium oxalate and calcium sulfate, however, the effect is mild and the process isn't the key influencing factor in the total ash content of Dioscoreae Rhizoma. During the preparation of Dioscoreae Rhizoma medicinal slices, water-soaking can cause the great loss of water-soluble mineral salts, such as Cl-, C2 O4 2-, NO3 - and SO4 2-, which leads to the reduction of total ash content, therefore, water-soaking is the key influencing factor in the total ash content of Dioscoreae Rhizoma.

Objective To investigate the incidence and clinical presentation of breast milk transmitted cytomegalovirus (CMV) infection among preterm infants with birth weight≤1500 g.Methods Preterm infants enrolled in this study met the following inclusion criteria: birth weight≤1500 g, fed with CMV-positive breast milk and admitted into Neonatal Intensive Care Unit of Children's Hospital of Fudan University within 72 hours after birth from October 2015 to July 2016. And those with congenital digestive tract malformation or congenital CMV infection were excluded. Breast milk and infants' urine samples were regularly screened for CMV DNA by fluorescent quantitative polymerase chain reaction. Symptoms and laboratory findings in infants with CMV infection transmitted via breast milk were documented and analyzed. Differences in relevant parameters were analyzed usingChi-square test, Fisher's exact test,t test or Mann-WhitneyU test where appropriately.Results Sixty preterm infants breastfed with CMV DAN-positive milk were recruited. Among them, 19 (31.7%) developed breast milk-acquired CMV infection as their urine samples were positive for CMV DNA, while the others were negative for CMV DNA (infected group:n=19; non-infected group:n=41). The average CMV copies in breast milk, gestational age and birth weight of the infected group were all significantly higher than those of the non-infected group [3.76 (3.18-4.50) vs 3.47 (3.00-4.88) Log10 copies/ml,Z=-2.042;(30.4±2.1) vs (28.4±2.3) weeks,t=3.175; 1290 (750-1500) vs 1110 (575-1480) g,Z=-2.837; all P<0.05). Fewer infants in the infected group than in the non-infected group received blood transfusion [5/19 vs 56.1%(23/41),χ2=4.627,P<0.05]. Ages of the infants with CMV infection ranged from 26 to 164 days (median age of 92 days). Six out of the 19 infants had clinical symptoms concurrent with viral excretion in urine and the ages of these symptomatic infants of infection were earlier than those of the asymptomatic ones without significance [(72±34) vs (97±28) days,t=-1.710,P>0.05]. Four infants (21.1%, 4/19) had severe organ damage and/or positive IgM antibodies to CMV in serum, and were treated with antiviral therapy. Two had mild symptoms and were not given antiviral therapy. All of the six symptomatic infants were followed-up for one to six months, during which time the complete blood cell count and results of biochemical test and fundus examination were back to normal.Conclusions The incidence of breast milk-acquired CMV infection among preterm infants with birth weight≤ 1500 g was 31.7%, and no severe symptoms were reported in this study.

The repair of bone defects poses a great challenge for reconstructive surgeons. Although the development of tissue engineering has exhibited promise in replacing damaged bone, the fabrication of large constructs with functional blood vessels remains an obstacle. From the orthopedic surgeon's point of view, the generation of axially vascularized bone, which can anastomose with the recipient vessel, might be a solution to this medical problem. In this study, we aimed to prefabricate an axially vascularized bone by combining a β-TCP scaffold, arteriovenous loop (AVL), and cell sheet in a bioreactor in vivo. Twelve rabbits were randomly allocated into two groups: the experimental group (presence of AVL) and the control group (absence of AVL). The constructs were explanted at 8 weeks postoperatively. The histomorphometric results showed 42.8±5.9% of the bone area in the AVL group and 26.6±3.5% in the control group. Similarly, vessel analysis revealed the average vessel density in the AVL group (12.5±3.3) was significantly more than that in the control group (6.1±1.5, p<0.05). Our research indicated that the combination of a β-TCP scaffold, AVL and cell sheet might engineer vascularized bone. This prefabrication strategy might facilitate clinical translation of bone tissue engineering in reconstructing large bone defects.

OBJECTIVETo determine the levels of urinary soluble intercellular adhesion molecule-1 (sICAM-1) and vascular cellular adhesion molecule-1 (VCAM-1) in patients with lupus nephritis (LN), and explore their correlation with renal disease activity.

METHODSUrine samples were collected from 92 renal biopsy-proven LN patients and 20 healthy controls. Renal disease activity was determined according to the ISN/RPS 2003 Revised Classification of Lupus Nephritis. The urine levels of sICAM-1 and VCAM-1 were detected by enzyme-linked immunosorbent assay, and the expressions of intrarenal ICAM-1 and VCAM-1 were evaluated by immunohistochemisty staining.

RESULTSUrinary sICAM-1 and VCAM-1 levels were elevated in LN patients compared with the controls. Significantly higher levels of urinary sICAM-1 and VCAM-1 were found in patients with active LN, who had also significantly increased intrarenal expressions of ICAM-1 and VCAM-1 compared with patients in remission. A strong positive correlation was noted between intrarenal expression and urine levels of ICAM-1 and VCAM-1. The receiver-operating characteristic (ROC) curve of urine sICAM-1 showed tan area under ROC curve of 0.874 for all participants in the test. A cutoff of 1095.00 pg/mg creatinine yielded a good sensitivity (0.945) and specificity (0.789). The ROC curve of urine VCAM-1 showed an area under ROC of 0.882 for all the participants, and a cutoff of 898.11 pg/mg creatinine yielded a good sensitivity (0.982) and specificity (0.667).

CONCLUSIONUrine sICAM-1 and VCAM-1 levels are positively correlated with their intrarenal expressions and reflect the activity of the nephritis, and therefore they may serve as potential biomarkers for early diagnosis of active LN.
