Objective: To investigate the effects of supplementing multivitamins on the growth and development of children. Methods: A total of 24 000 children (6 8 years old) from Shanghai, Beijing and Guangzhou were divided into 2 groups. One group was given multivitamin tablets and another was without any treatment for 12 weeks. Each tablet contains VA 5 000 IU, VD 400 IU,VE 30 IU,VB 1 1.5 mg,VB 2 1.7 mg,niacin 20 mg,VB 6 2 mg,VB 12 6 ?g,folic acid 0.4 mg and VC 60 mg. Height, body weight, skinfold thickness, mid arm muscle circumference and serum VA, 25 OHD 3, Hb, IgA,IgG and IgM were measured before and after supplementing multivitamins.VB 1, VB 2 and VC were evaluated by four hours loading test. Results: It was found that vitamin deficiencies, especially that of VA, VB 2 and VB 1, existed in the children. After supplement, the net increase of height and weight was significantly higher than that of control group. Levels of serum VA, 25 OHD 3 and Hb in supplemented group were significantly increased and the urinary excretion of VB 1, VB 2 and VC was also significantly increased in supplemented group. Conclusion: The results indicate that the multivitamins is conductive to improvement of vitamin status and nutritional anemia, and to growth and development. It is necessary for children with routine diet to supplement multivitamins. [

Drug research involves scientific discovery, technological inventions and product development. This multiple dimensional effort embodies both high risk and high reward and is considered one of the most complicated human activities. Prior to the initiation of a program, an in-depth analysis of "what to do" and "how to do it" must be conducted. On the macro level, market prospects, capital required, risk assessment, necessary human resources, etc. need to be evaluated critically. For execution, drug candidates need to be optimized in multiple properties such as potency, selectivity, pharmacokinetics, safety, formulation, etc., all with the constraint of finite amount of time and resources, to maximize the probability of success in clinical development. Drug discovery is enormously complicated, both in terms of technological innovation and organizing capital and other resources. A deep understanding of the complexity of drug research and our competitive edge is critical for success. Our unique government-enterprise-academia system represents a distinct advantage. As a new player, we have not heavily invested in any particular discovery paradigm, which allows us to select the optimal approach with little organizational burden. Virtue R&D model using CROs has gained momentum lately and China is a global leader in CRO market. Essentially all technological support for drug discovery can be found in China, which greatly enables domestic R&D efforts. The information technology revolution ensures the globalization of drug discovery knowledge, which has bridged much of the gap between China and the developed countries. The blockbuster model and the target-centric drug discovery paradigm have overlooked the research in several important fields such as injectable drugs, orphan drugs, and following high quality therapeutic leads, etc. Prejudice against covalent ligands, prodrugs, nondrug-like ligands can also be taken advantage of to find novel medicines. This article will discuss the current challenges and future opportunities for drug innovation in China.

AIM: To verify the neuroprotective effect and optimize the therapeutic dose and time window of picroside Ⅱon cerebral ischemic injury in rats .METHODS:The forebrain ischemia model was established by the method of bilateral common carotid artery occlusion ( BCCAO ) .The successful model rats were randomly divided into 16 groups according to orthogonal design and treated by intraperitoneal injection of picroside Ⅱat different ischemic time poinis and different doses .The changes of the nerve fiber myelin were observed by fast green staining .The immunohistochemical assay and Western blotting were used to quantitatively and qualitatively determine the expression of myelin basic protein (MBP). The mRNA level of MBP in the brain tissues was tested by reverse transcription polymerase chain reaction (RT-PCR).RE-SULTS:Picroside Ⅱ increased the expression of MBP and decreased demyelination after cerebral ischemic injury .The best therapeutic time window and dose were:(1) ischemia for 2.0 h with picrosideⅡat dose of 10 mg/kg according to the results of fast green staining;(2) ischemia for 2.0 h with the dose of 10 mg/kg according to the results of immunohisto-chemical assay;(3) ischemia for 2.0 h with the dose of 10 mg/kg according to the analysis of Western blotting;(4) is-chemia for 1.5 h with the dose of 20 mg/kg according to the detection of RT-PCR.CONCLUSION:Given the principle of the lowest therapeutic dose with the longest time window , the optimized therapeutic dose and time window for rat cerebral ischemic injury is intraperitoneal injection of picroside Ⅱat the doses of 10~20 mg/kg and the time window of ischemia for 1.5~2.0 h.

The pathogenesis of migraine is not fully understood as yet. Recently, with the development of ultrasonography, some stud-ies indicated that the prevalence of right-to-left shunt (RLS) seemed to be higher in migraine, especially in migraine with aura. The progress in the relationship between migraine and RLS was reviewed.

BACKGROUND:Cartilage scaffold plays an important role in articular cartilage injury, but it is stil restricted in practice, leading to the repair failure using tissue-engineered cartilage. OBJECTIVE:To explore the preparation method of cartilage scaffold with directional structure and its repairing effect in cartilage injury of rabbits. METHODS:Directional cartilage scaffolds were prepared by temperature gradient induced phase separation technique. The cross-linking of cartilage scaffold was completed with genipin. The physical and mechanical properties of scaffolds were determined. Forty-eight white rabbits were modeled into exercised-induced articular cartilage injury and equivalently randomized into two groups, fol owed by implantation of non-directional or directional scaffolds. Samples were col ected at postoperative 6, 12 and 24 weeks to compare the repair effect of two scaffolds on rabbit joint injury. RESULTS AND CONCLUSION:Scanning electron microscope showed that the regular microstructures on the longitudinal section of directional scaffolds were aligned in the same direction, while the longitudinal and transverse planes of the non-directional scaffolds showed porous honeycomb structures. The elastic modulus of the directional scaffold was significantly higher than that of the non-directional scaffold (P<0.05). O’Driscol histological scores in the directional scaffold group were significantly higher than those in the non-directional scaffold group at 6, 12 and 24 weeks postoperatively (P<0.05). At postoperative 24 weeks, in the directional scaffold group, the three-dimensional reconstruction of the rabbit defect region was flat and smooth, and coronal two-dimensional scanning showed the cartilage thickness of the newborn cartilage was very close to that of the normal bone;the cartilage surface in the non-directional rabbits was flat under three-dimensional CT, and coronal two-dimensional scanning showed that the repaired cartilage was almost the same as the normal cartilage. Hematoxylin-eosin staining showed that at 24 weeks postoperatively, the defect site disappeared and the cartilage cel s arranged in the vertical direction in the directional scaffold group. There were typical cartilage lacunae at the defect site in the non-directional scaffold group at 24 weeks postoperatively. Our findings suggest that the directional cartilage scaffold prepared using temperature gradient induced phase separation technique holds good physical and mechanical properties, and its implantation into the rabbit articular cartilage injury induced by exercise can promote the injury repair to obtain ideal mechanical properties.

Objective To determine the role of SCN1A gene variation in the development of familial febrile seizures (FS).Methods Clinical data were collected from 8 familial FS pedigrees, and peripheral venous blood samples were collected from the probands and other available family members. All 26 coding exons and exon-intron boundaries at least 50 bases of the human SCN1A gene were amplifled by polymerase chain reaction, the products were subsequently sequenced. To novo variation, other family members were screened for the corresponding exons. Two hundred age-matched healthy children were served as normal controls. ResultsA total of 33 variations in the SCN1A gene were identifled in these families. Of these variations, one was a missense mutation; the remaining 32 variations were previously submitted as single nucleotide polymorphisms (SNPs). A c.2650G>A heterozygous missense mutation in exon 15 of the SCN1A gene found in the proband of family 4 was inherited from his father who had seizures with fever in early childhood. The c.2650G>A mutation was absent in the 400 alleles of normal controls. To the best of our knowledge, the SCN1A c.2650G>A mutation has neither been reported in the NCBI SNP database nor in the literature to date. The c.2650G>A mutation changes a glycine at amino acid 884 in the SCN1A protein to a serine (p.Gly884Ser). Protein sequence analysis showed that the p.Gly884Ser is located at a highly conserved region between the 4th and 5th transmembrane segment of the homologous domain Ⅱ of voltage-gated sodium channel 1 subunit (DIIS4-S5). ConclusionsThe pathogenesis of familial febrile seizures was related to the SCN1A variation, the mutation outside the region of the voltage sensor (S4) and ion channel pore (S5-S6) of the voltage gated sodium channelα-subunit may be an important factor to cause mild phenotype epilepsy syndrome.

Angiogenesis plays a critical role in growth and metastasis of lung cancer.The strongest tumor angiogenesis factor known is the vascular endothelial growth factor (VEGF).Therefore,anti-VEGF therapy which can restrain tumor angiogenesis is an important form of the targeted therapy of lung cancer.The expression of VEGF is also significant to the prognosis of lung cancer.
