ObjectiveTo understand dangerous factors causing child cerebral palsy and try to diagnose and treat cerebral palsy early, and decrease the ratio of cripple.MethodsTo analyze if the occurrence, style or complication of cerebral palsy having a relation to dangerous factors such as sexes, birth weight, premature delivery, twins, neonatal asphyxia, infection of newborn, nuclear icterus, mother's age, virus infection in the duration of pregnancy, threatened abortion and family history of cerebral palsy.ResultsThe ration of male and female is 1.47∶1 in 146 cases of child cerebral palsy. Factors causing cerebral palsy are low birth weight (79.45%), premature delivery (64.38%), neonatal asphyxia (41.78%), threatened abortion (32.89%), twins (31.53%), infection of newborn (12.33%), nuclear icterus (6.16%), parturient with advanced age (3.42%), having infection history in the duration of pregnancy (2.74%), and family history of cerebral palsy (0.68%). Both styles and complications of cerebral palsy have a relation to dangerous factors.ConclusionsThe low birth weight, premature delivery, neonatal asphyxia, twins and threatened abortion all are higher dangerous factors causing child cerebral palsy. In order to abstain the occurrence of these dangerous factors, it is important to educate people and doctors recognizing all dangerous factors. It is also helpful to lower the ratio of cripple that regularly examining child with dangerous factors, discovering symptoms and complications of cerebral palsy in time, and diagnosing and treating cerebral palsy as soon as possible.

Objective To explore effect of probiotics on improving the feeding intolerance in very low birth weight infants(VLBWI). Methods Sixty cases of VLBWI were randomly divided into two groups, 30 infants as therapy group,another 30 infants as control group.All infants in two groups were given aggressive intravenous nutrition and enteral feeding with preterm formulars. At the same time, probiotics were administered combined with preterm formulars to infants in therapy group. Milk amount, gastric residual, initial time of enteral feeding, time required for full enteral feeding and body weight on day 21 after birth were all recorded.Results Rate of no gastric residual increased significantly in therapy group compared with that of control group(t=6.24 P

Objective To explore the clinical value of imaging examinations of medullary sponge kidney with the literature reviewed.Methods The features of X-ray plain film (1 case),IVP (2 cases),B-mode US(3 cases) and CT images (9 cases) of medullary sponge kidney (MSK) in 11 cases were analysed retrospectively.Results X-ray plain film showed a cluster of round and oval high density images in renal papillae and renal medulla in one case one kidney.Collecting tubes were showed as like line,brush and sac like dilatation on IVP in 2 cases 3 kidneys.B-mode US revealed a cluster of high echo spots scattered in renal medulla in 3 cases 5 kidneys and sac like dilatation of collecting tubes in 2 cases 3 kidneys.CT images showed the stones of spongiform kidney scattered alone renal medulla in 9 cases 16 kidneys,while the stones covered by contrast media on enhanced CT images in 3 cases 5 kidneys,and enhanced stripes of high density projected from renal papillae to renal medulla.Conclusion X-ray plain film,IVP,B-made US and CT all can be used in diagnosing spongiform kidney.Plain film and IVP are yet the first selected methods and IVP is specific and direct in showing collecting tubes dilatation.B-mode US especially CT have a high showing rate of stone in spongiform kidney and can be helpful to evaluate the collecting tube dilatation.

A new dynamic in vitro intestinal absorption model for screening and evaluating lipid formulations was established by means of the characteristics of the intestinal digestion and absorption of the lipid formulations. This model was composed of two systems, including intestinal digestion and the intestinal tissue culture, which drew the evaluation method of intestinal absorption into the in vitro lipolysis model. The influence of several important model parameters such as Ca2+, D-glucose, K+ on the two systems of this model has been investigated. The results showed that increasing of Ca2+ concentration could be significantly conductive to intestinal digestion. The increasing of D-glucose concentration could stepped significantly down the decay of the intestinal activity. K+ was able to maintain intestinal activity, but the influence of different concentration levels on the decay of the intestinal activity was of no significant difference. Thus the model parameters were set up as follows: Ca2+ for 10 mmol x L(-1), D-glucose for 15 mmol x L(-1) and K+ for 5.5 mmol x L(-1). Type I lipid formulation was evaluated with this model, and there was a significant correlation between the absorption curve in vitro and absorption curve in vivo of rats (r = 0.995 6, P < 0.01). These results demonstrated that this model can be an attractive and great potential method for the screening, evaluating and predicting of the lipid formulations.

This paper report the development of a new dosage form - self-microemulsifying mouth dissolving films, which can improve the oral bioavailability of water insoluble drugs and have good compliance. A three factor, three-level Box-Behnken design was used for optimizing formulation, investigated the effect of amounts of microcrystalline cellulose, low-substituted hydroxypropyl cellulose and hypromellose on the weight, disintegration time, cumulative release of indomethacin after 2 min, microemulsified particle size and stretchability. Optimized self-microemulsifying mouth dissolving films could fast disintegrate in (17.09 +/- 0.72) s; obtain microemulsified particle size at (28.81 +/- 3.26) nm; and release in vitro at 2 min to (66.18 +/- 1.94)%. Self-microemulsifying mouth dissolving films with broad application prospects have good compliance, strong tensile and can be released rapidly in the mouth through fast self-microemulsifying.

Solid carriers had important effects on the properties of solid self-microemulsifying drug delivery systems (S-SMEDDS). In order to make the basis for further development of S-SMEDDS, the influences of silica on the absorption of S-SMEDDS were investigated. An in vitro lipolysis model was used to evaluate the influence of silica on self-microemulsifying drug delivery system digestion from intestinal tract. S-SMEDDS containing silica were prepared by extrusion/spheronization. The drug release and absorption were investigated. The results showed that lipolysis rate and drug concentration in aqueous phase after intestinal lipolysis both increased by adding silica, which was benefit to drug absorption. And silica was not benefit to absorption for slowing drug release. Consistently, there was no significant influence of silica on intestinal absorption. This study implied that the influences of silica on lipolysis rate and drug release were both amount dependent and it is suggested that silica could be used as the solid carrier but the proportion needs to be optimized.

Objective To construct and express recombinant cecropin B-binding site of luteinizing hormone releasing hormone(CB-LHRH')gene,and to evaluate the anticancer function of CB-LHRH' on human ovarian cancer cell line SKOV3 and human endometrial cancer cell line HEC-1B.Methods The sequence of the cDNA encoding CB-LHRH' was designed,artificially synthesized,verified by DNA sequence analysis and expressed by Bac-to-Bac baculovirus expression system.The expression of CB-LHRH' proteins were identified by western dot blot using rabbit polyclonal antibody against LHRH as the primary antibody.To determine the anticancer effects of the CB-LHRH' protein,ovarian cancer cell line SKOV3 and endometrial adenocarcinoma cell line HEC-1B were treated by different doses of the CB-LHRH' protein.Cell growth inhibition assay was performed using the 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)5[(phenylamino) carbonyl]-2H-tetrazolium hydroxide(XTT)kit at different times,and cell morphologic changes were observed under the inverted microscope.Results The inhibitory rate of proliferation by CB-LHRH' increased with the increase of dose and time respectively:SKOV3 cell,from(5.03?0.08)% to(53.24 ?1.22)%;HEC-1B cell,from(5.13?0.37)% to(56.16?1.08)%.The inhibitory effect on HEC-1B cell was stronger than that on SKOV3 cell(P
