Objective To explore the psychomotor development in 12 month old infants born after in vitro fertilization with a control group of infants concieved naturally.Methods A matched control study was performed on psychomotor development of 12-month-old infants concieved with use of assisted reproductive technology(in vitro fertilization only).The control group was matched according to maternal age,parity,social class and level of parental education.The suitable mothers were invited to participate at the 28th week of gestation and were followed up to delivery.The infants of the two groups were followed up to 12 months old and a formal developmental assessment was done with the Children Development Center of China(CDCC) scales of infant development.Results The incidences of preterm birth,low birth weight and twin pregnancy were significantly higher in the assisted conception group.No statistically significant difference was found in the mental development index and psychomotor development index between assisted conception and control groups.Conclusions The levels of psychomotor development in 12 months old infants born after in vitro fertilization are normal.But as the incidences of preterm birth,low birth weight and multifetation are significantly higher in vitro fertilization group,it need to follow up the ongoing development of these children.

The technique of liquisolid compress is a new technique developed in 1990s, which was considered to be the most promising technique to improve the dissolution of water-insoluble drugs. In this article, tanshinone II(A) and the extracts of the ester-solubility fractions were chosen as the model drugs to evaluate the effects of the liquisolid technique for enhancement of dissolution properties of tanshinone II(A). Several liquisolid tablets (LS) formulations containing different dosage of drugs and various liquid vehicle were pre-pared and for all the formulations, microcrystalline cellulose and silica were chosen as the carrier and coating materials to evaluate their flow properties, such as angle of repose, Carr's compressibility index and Hausner's ratio. The interaction between drug and excipients in prepared LS compacts were studied by differential scanning calorimetry(DSC) and X-ray powder diffraction (XRPD). The dissolution curves of tanshinone II(A) from liquisolid compacts were investigated to determine the technique's effect in improving the dissolution of tanshinone II(A) and its impacting factors. According to the results, the dissolution increased with the rise in the dissolution of the liquid-phase solvent. The R-value and drug dosage can significantly affect the drug release, but with less impact on active fractions. This indicated that liquisolid technique is a promising alternative for improvement of dissolution property of water-soluble drugs, and can make a synergistic effect with other ester-soluble constituents and bettern improve the release of tanshinone II(A). Therefore, the technique of liquisolid compress will have a better development prospect in traditional Chinese medicines.

Objective To observe the survival, migration and differentiation of adipose-derived adult stem (ADAS) cells and the recovery of motor function of ischemic rats after ADAS cell transplantation. Methods Eighteen adult male SD rats, weighted about 250-300 g, were chosen and received left middle cerebral artery occlusion (MCAO) operation. And then, they were equally randomized into untreated group, control group and ADAS cell transplantation group. Tail vein injection of Dulbecco's modified eagles medium (DMEM) and ADAS cells were performed in the control group and ADAS cell transplantation group 3 h after MCAO, respectively. These animals were euthanized 14 d after MCAO. Immunofluorescence for BrdU, NSE, MAP-2 and GFAP were processed to identify the survival, migration and differentiation of grafted ADAS cells in the brain, and at the same time, scores of neurological deficit scale were used to assess the improvement of motor function. Results After the transplantation, numerous ADAS cells labeled with BrdU were presented in the ischemic points and surrounding areas. A few BrdU/GFAP, BrdU/NSE and BrdU/MAP-2 -positive cells were noted in the ischemic points of ADAS transplantation group 14 d after MCAO. The neurological functional recovery in the ADAS cell transplantation group was significantly improved as compared with that in the control group 14 d after MCAO (P＜0.05). Conclusion ADAS cells can migrate into the ischemic hemisphere and differentiate into neuron-like and astrocytic-like cells after the injection by venous approach in the rat models with MCAO. The intravenous administration of ADAS cells into rats with MCAO leads to good functional outcome and few lesion sizes.

AIM:To explore the protective effect of morinda officinalis oligosaccharides monomer HexB on hy -poxia/reoxygenation(H/R)-induced injury in human umbilical vein endothelia cells(HUVECs).METHODS:HUVECs were treated with HexB,4-phenylbutyric acid(4-PBA)and thapsigargin(TG),respectively.The cells were divided into control group,HexB group,H/R group,HexB+H/R group,4-PBA+H/R group,TG group and HexB+TG group.The cell viability was measured by CCK-8 assay.The apoptotic rate was detected by flow cytometry.Western blot was used to determine the protein levels of endoplasmic reticulum stress(ERS)related molecules chaperone protein glucose-regulated protein 78(GRP78),C/EBP homologous protein(CHOP),apoptosis-related protein caspase-12 and phosphorylated c-Jun NH2-terminal kinase(p-JNK).RESULTS: The viability of HUVECs was reduced in H/R group and TG group(P<0.05),increased in HexB+H/R,4-PBA+H/R and HexB+TG group(P<0.05).The apoptotic rate,the protein levels of GRP78,CHOP,caspase-12 and p-JNK were increased in H/R group and TG group(P<0.05),weakened in the HexB+H/R group(P<0.05),4-PBA+H/R group and HexB+TG group(P<0.05).No significant change in the apoptotic rate,cell viability,protein levels of GRP78, CHOP, caspase-12, p-JNK between HexB +H/R group and 4-PBA+H/R group was observed.CONCLUSION:HexB attenuates HUVECs injury caused by H/R through suppressing ERS and ap-optosis.The possible mechanism may be involved in the apoptotic pathways related to GRP 78,CHOP,caspase-12 and p-JNK.

To provide a scientific basis for the selection of the appropriate drying method for Mentha Haplocalyx Herba (MHH), determine 2 monoterpenes, 4 phenolic acids and 5 flavonoids in MHH by GC-MS and UPLC-TQ-MS methods, and investigate the effects of the drying methods on the changes in contents of these analytes. The qualities of products obtained with different drying methods were evaluated by the multivariate statistical method of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Results showed that the drying methods had the greatest impact on menthol, caffeic acid, and rosemary acid, which were followed by chlorogenic acid and diosmetin-7-O-glucoside. The contents in these analytes processed with hot-air-drying method were higher than those with microwave-drying and infrared-drying methods at the same temperatures. The contents in these analytes processed under low temperature (40-45 °C) were higher than those under higher temperature (60-70 °C). Above all, the contents in phenolic acids processed with microwave fixation (exposed under microwave at 100 °C for several minutes) were obviously higher than those of not being processed, showing an inhibition of some enzymes in samples after fixation. The TOPSIS evaluation showed that the variable temperature drying method of 'Hot-Air 45-60 °C' was the most suitable approach for the primary drying processing of MHH. The results could provide the scientific basis for the selection of appropriate drying method for MHH, and helpful reference for the primary drying proces of herbs containing volatile chemical components.

OBJECTIVETo observe the effect of electroacupuncture on supplementary analgesia and improvement of adverse reactions induced by dolantin in oocyte retrieval, and to provide scientific and effective evidence for application of electroacupuncture in oocyte retrieval.

METHODSOne hundred and thirty-four patients undergoing in vitro fertilization and embryo transfer (IVF-ET) were randomly divied into an observation group and a a control group, 67 cases in each group. They were all received intramuscular injection of 50 mg dolantin at 30 mn before the operation, and then the observation group was treated with acupuncture at Baihui (GV 20), pain point (Extra, right), Sanyangluo (TE 8, right), Zusanli (ST 36, right) and ear uterus point (right ear). Pain point and Sanyangluo (TE 8) were received electroacupuncture stimulation after Deqi until the oocyte retrieval operation was finished, and the oocyte retrieval operation was performed in the control group after 30 min of injection of dolantin. The pain grade and score were observed and the adverse reactions during operation or 1 h and 2 h after the operation were recorded.

RESULTSThe excellent analgesia rate was 97.0% (65/ 67) in the observation group and 92.5% (62/67) in the control group, with significant difference in the analgesia effect (P < 0.05). The pain grade and pain score in the observation group were both superior to those in the control group (both P < 0.05). There were fewer cases with the adverse reactions i.e. vertigo, sweating, nausea in the observation group than that in the control group during operation or 1 h and 2 h after the operation (all P < 0.05).

CONCLUSIONIn the oocyte retrieval operation, under the guidance of vaginal B ultrasound, electroacupuncture has a good intraoperative supplementary analgesia effect without intraoperative and postoperative adverse reactions induced by dolantin.
