Late preterm is labeled near term. As developmental immaturity, there was higher morbidity in late preterm infants compared with term infants. Especially brain injury, a 3-fold increased risk of cerebralpalsy and significantly higher rates of developmental delay and mental retardation for late preterm infants compared with term infants. In addition, a higher rates of neonatal complications had been documented on late preterm infants. These problems included apnea, hypoglycemia, hyperbilirubinemia, respiratory distress syndome, and poor feeding. It was known that long-term impact of these diseases will result in brain injury.

Objective To investigate the influence of psychological intervention on the anxiety of patients with obstructive jaundice and supply theoretical reference for psychological evaluation and nutsing.Methods 129 patients with obstructive jaundice was divided into the intervention group(64 cases)and the control group(65 cases).The control group adopted routine treatraent method such as anti-infection,liver protection treatment,enhancement of coagulation mechanism and supporting treatment.The intervention group received psychological nursing,relaxation training and distraction of attention based upon routine nursing.The degree of anxiety and pruritus was obseved and recorded in the two groups.Results The degree of anxiety in the intervention group was evidently lower than that of the control group(P＜0.01).The degree of pruritus in the intervention group was 18.75%,which was statistically different from that of the control group(35.38%),P＜0.05.Condusion Adoption of psychological intervention could effectively reduce the degree of anxiety and pruritus of patients with obstructive jaundice.

Nitrogen pollution in water body can not only cause eutrophication but also has direct hazardous effects on animals and human beings. The removal of ammonium is an important process in modern wastewater treatment systems. It is generally achieved by a traditional treatment system of combination of two processes,aerobic nitrification and anoxic denitrification,but these processes are very complex and the cost is higher. In recent years,some new principles have been proposed,such as aerobic denitrification,anaerobic ammonium oxidation,heterotrophic nitrification,which make simultaneous nitrification-denitrification possible. The domestic and foreign study progress in aerobic denitrification was reviewed in this paper.

OBJECTIVE:To establish a method for the concentration determination of indigo in rats'plasma,and study the pharmacokinetic characteristics in rats in vivo. METHODS:18 rats were randomly divided into low-dose,medium-dose,high-dose groups,6 in each group,which were intragastrically administrated 10,20,40 mg/kg of indigo solution. The sample blood 0.3 mL was taken from eye socket before administration and 0.083,0.25,0.5,0.75,1,2,4,6,8,10,12,16,24,48,72 h after ad-ministration,separating the plasma,then LC-MS/MS was used to determine the plasma concentration of indigo after methanol pre-cipitation. The column was Agilent Poroshell EC-C18 with mobile phase consisting of methanol-5 mmol/L ammonium acetate solu-tion(95:5,V/V)at a flow rate of 0.4 mL/min;multiple reaction monitoring was conducted for the quantitative analysis,with ion pair of 263.1-218.8 (indigo) and 237.2-194.1 (carbamazepine,internal standard). Pharmacokinetic parameters were calculated by DAS 3.0 software. RESULTS:The linear range of indigo was 0.5-100 ng/mL(r=0.9999),intra-day and inter-day RSDs were low-er than 9%(n=5);matrix effects of low,medium and high does quality control samples were (98.25 ± 3.71)%,(102.23 ± 2.64)%,(102.29±3.79)%(n=5). The pharmacokinetic parameters of indigo in low-dose,medium-dose,high-dose groups were tmax of(8.6±1.1),(9.2±0.8)and(9.5±0.8)h;cmax of(30.9±8.6),(44.9±10.1),(96.1±17.4)ng/mL;t1/2 of(14.9±2.1), (16.3±2.9),(15.3±3.7)h;AUC0-72 h of(366.6±83.4),(694.9±105.8),(1223.42±108.7)ng·h/mL,respectively. CONCLU-SIONS:The method shows high sensitivity,good specificity,and can be used for the content determination of indigo in plasma samples of rats. The pharmacokinetics of indigo in rats in vivo fits non-compartment model.

Transarterial chemoembolization is an important treatment for advanced primary hepatic carci -noma.Along with the development of TACE therapy , more and more antineoplastic drugs have been used in transarterial chemoembolization .However,the side effects and the efficacy of the drugs are still not very clear . Therefore,we summarize and compare the mechanism of actions ,efficacies and side effects of these drugs in this paper .

Chemical constituents of the aerial parts of Qianhu were compared with those present in the roots by RP-HPLC. It was found that the constituents in aerial parts of Peucedanum praeruptorum are similar and higher in content than that in the roots. So it is possible that the aerial parts can be used instead of the roots of the plant. But the chemical constituents in the aerial parts and the roots of P. decursivum are quite different, rendering it impossible to use the aerial parts instead of the roots of the plant.

Vitamin D ( VD) has been stated clearly in maintaining the balance of serumcalcium and phosphorus in human . Whereas, more and more evidences show VD has a considerable range of other physiological functions .VD has also been proposed to have vital functions controversially including adjusting immunity, antitumor, enhancing barrier in the intestine .The patients of short bowel syndrome are at particularly high risk of vitamin D deficiency .It has a significance in prevention and treatment of diseases to fur-ther clearly clarify the relationship and mechanisms of VD and the diseases .

Objective To investigate the effect of sanbai granules on the patients with leucoderma.Methods 180 cases with leucoderma were selected and divided into two groups.90 cases in the control group were treated by Methoxsalen Tablets 10mg,1 times a day,2h sunlight after the medication,appropriate amount external of Compound Kaliziran tincture and Halometasone.90 cases in the experiment group were treated on the base of the control group with Sanbai granules.The activity of tyrosinase,amount of melanin in the serum,clinical effect and amount of skin regeneration between two groups were compared.Results Compared with the control group, the activity of tyrosinase and melanin in serum of the experiment group were higher (P<0.05),the clinical effect rate were higher(P<0.05),number of skin regeneration piece was higher(P<0.05).Conclusion Sanbai granules can effectively improve the activity of tyrosinase and melanin in patients with leucoderma, and it has important significance for the treatment of leucoderma.
