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 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.

Chinese herbs with bitter flavor have the function of purgation and dryness as well as strengthening yin.Strengthening Yin means keeping and maintaining yin fluid.Actually,it is to draw assistance from some Chinese herbs with bitter flavor to purge excessive fire in order to maintain yin qi by heat-clearing and fire-purging,that is to say purging fire to keep or save yin.Strengthening yin of bitter herbs is different from the moistening and nourishing function of sweet-cold herbs.It can be generally divided into three aspects: purging ministerial fire and restoring renal yin,clearing heat and purging fire to maintain yin fluid;purging to preserve yin.Strengthening yin doesn't mean the property and flavor of bitter-cold can nourish yin directly.We should not only emphasize clearing fire by using herbs with bitter in flavor and cold in nature,but also pay attention to nourish yin.It is causal relation that exists between purging fire and maintaining yin.The former is only a means and method,and the latter is objection and effect.Because the bitter-flavor can only damage yin by bitterness and dryness but is not good at benefiting yin,we cannot strengthen yin by using bitter herbs in treating yin-deficiency syndrome without excessive fire.

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.

Bronchial asthma is defined as a chronic inflammatory airway disease in response to a wide variety of provoking stimuli.Over 200 million people in the world are affected with asthma.Because the incidence of asthma appears to be increasing,the importance of proper perioperative management of persons with asthma will also continue to increase.Patients with asthma are thought to be at high risk for pulmonary complications to develop during the perioperative period,and these complications may lead to serious morbidity.So it is very important to control asthma,to prevent and treat pulmonary complications for increasing operational success rate.

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.

The implementation,operation and maintenance of building have huge impacts on environment and human health,however,the research about quantitative assessment of damage to human health for construction project still does not appear in China.Based on investigation in literatures about five LCA-based environmental impact assessment systems(EIA) systems,this paper concluded and compared the of health damage parts of the systems referred.Finally,some suggestions for establishing assessment systems of damage to human health especially in health damage indicators selection,characterization and weighting were proposed.

OBJECTIVE:To provide reference for the implementation of national essential drugs system. METHODS:Based on the experience on the implementation of national essential drugs system in the past year,relevant policies about essential drugs system were analyzed to probe into several issues on its implementation. RESULTS & CONCLUSION:The legal place of National essential drugs system should be further confirmed and qualification authentication of pharmaceutical enterprises involved in bidding for essential drugs list need to be standardized. Subject and proportion of essential drug use must be ensured as well as the supply of essential drugs to make sure the implementation of national essential drugs system.

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 .

Objective To develop a double-wavelength HPLC method for the simultaneous determination of neogambogic acid,gambogic acid,( +)-catechin and L-epicatechin in Litong pill. Methods The quantitative analysis was carried out on C18 column(250 mm×4.6 mm,5 μm).A linear elution of methanol-acetonitrile(4: 1)and 0.2% phosphoric acid solution was adopted at the flow rate of 1.1 mL·min-1 ,with the detection wavelength set at 360 nm for neogambogic acid and gambogic acid,and at 280 nm for(+)-catechin and L-epicatechin. Results The linear ranges of neogambogic acid,gambogic acid,(+)-catechin and L-epicatechin were 5.85-117.00 μg·mL-1(r= 0.999 5),8.95-179.00 μg·mL-1(r= 0.999 8),6.90-138.00 μg·mL-1(r= 0.999 7),and 5.30-106.00 μg·mL-1(r = 0.999 9),respectively.The average recoveries were 97.82%(RSD= 1.21%),98.72%(RSD = 1.30%),96.96%(RSD = 0.84%)and 99.26%( RSD = 1.46%)for neogambogic acid, gambogic acid,(+)-catechin and L-epicatechin,respectively. Conclusion The method is simple,accurate,reproducible and may be used for the simultaneous determination of neogambogic acid,gambogic acid,(+)-catechin and L-epicatechin in Litong pill.
