The International Pediatric Multiple Sclerosis Study Group (IPMSSG) put forward the 2007 version of the diagnostic criteria for multiple sclerosis and other immune-mediated demyelinating diseases of the central nervous system in children in 2007 ("2007 version" for short). In 2012, IPMSSG proposed the new diagnostic criteria with reference to the latest research achievements of 150 members ("2012 version" for short). The 2012 version of the consensus statements covers the diagnostic criteria for acute disseminated encephalomyelitis, clinically isolated syndrome, neuromyelitis optica, and multiple sclerosis in children. As the two IPMSSG members in China, the authors give an interpretation of the 2012 version of the consensus statements with reference to related literature and clinical and scientific experience. The authors focus on how the 2012 version comprehensively and thoroughly elaborates on the clinical features, diagnostic criteria, influencing factors, and new ideas of acute demyelinating diseases of the central nervous system in children. These become more operable in clinical diagnosis and treatment of multiple sclerosis and other immune-mediated demyelinating diseases of the central nervous system in children.

Objective To analyze the relationship between pre － pregnancy body mass index ( BMI) ，gestational weight gain ( GWG) and the birth weight of infants，and explore the effect of weight change before and during pregnancy on low birth weight ( LBW) and macrosomia． Methods Women were enrolled by the Chinese Pregnant Women Cohort Study during first trimester． Each respondent＇s weight before and during pregnancy and the birth weight of infant were collected after fellow up． Prepregnancy BMI was divided into underweight，normal and overweight /obesity groups and GWG was divided into suitable， insufficient and excessive groups． Multivariate Logistic regression was adopted to explore the relationship be- tween pre－pregnancy BMI，GWG and newborn＇s birth weight． Ｒesults Women＇s prepregnancy BMI and GWG were associated with neonatal birth weight ( all P＜0. 05) ． Prepregnancy overweight or obesity ( OＲ=2. 339，95% CI: 1. 674－2. 282，P＜0. 001) and excessive GWG ( OＲ= 1. 398，95% CI: 1. 188－1. 978，P= 0. 048) were shown as risk factors for macrosomia． Insufficient GWG increased LBW risk ( OＲ = 1. 479， 95% CI: 1. 461－1. 679，P= 0. 035) while excessive GWG declined LBW risk ( OＲ= 0. 428，95% CI: 0. 225 －0. 817，P= 0. 010) ． Under weight－insufficient GWG was risk factor of LBW ( OＲ= 1. 335，95% CI: 1. 048 －2. 319，P= 0. 048) while normal BMI－excessive GWG ( OＲ= 1. 088，95% CI: 1. 016－1. 675，P= 0. 038) and overweight /obesity－excessive GWG ( OＲ= 1. 498，95% CI: 1. 244－2. 017，P= 0. 046) were associated with higher risk of delivering macrosomia． Conclusions Prepregnancy BMI and GWG were associated with infant＇s birth weight and women were suggested to maintain their weight in recommended range before and during pregnancy．

OBJECTIVETo further explore the pathogenesis of neonatal acute lung injury and neonatal pulmonary hemorrhage by establishing the animal model of neonatal acute lung injury (ALI) and by investigating the changes of platelet endothelial cell adhesion molecule-1 (PECAM-1), tissue type plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1) in ALI.

METHODSTotally 88 neonatal rats which were divided into 8 groups randomly including one normal saline control group and 30 min, 1 h, 2 h, 4 h, 8 h, 16 h and 24 h post injection groups. The changes of lung pathology in newborn rats were observed at different time after LPS was injected intraperitoneally. The changes of PECAM-1 protein, t-PA and PAI-1 mRNA expression were measured by immunohistochemistry and RT-PCR.

RESULTSThe expression of PECAM-1 protein and mRNA was decreased and the lowest level was reached at 8 h and 16 h post injection, respectively. The average values were 95.1 +/- 9.76 and 0.861 +/- 0.016, respectively, which were significantly lower than those in the control group (129.5 +/- 6.15, 1.192 +/- 0.035, P < 0.01). The expression of t-PA and PAI-1 mRNA was increased after LPS was injected. The highest level of t-PA mRNA expression was observed at 2 h after injection. The average value was 1.195 +/- 0.036, which was significantly higher than that in the control group (0.781 +/- 0.017, P < 0.01). The highest level of PAI-1 mRNA expression was observed at 2 h, 4 h and 8 h post injection. The average values were 1.178 +/- 0.069, 1.153 +/- 0.036 and 1.176 +/- 0.044, respectively, which was significantly higher than those of the control group (0.681 +/- 0.019, P < 0.01).

CONCLUSIONSThe expression of PECAM-1 protein and mRNA was decreased after LPS injection, suggesting the disruption of the tissue protective mechanism; the expression of t-PA and PAI-1 mRNA was increased, indicating the presence of a hypercoagulability state. At the same time, the expression of t-PA mRNA was increased which caused the extra-cellular matrix degradation at the early phase after LPS injection. These three phenomena might be the contributory factors to pulmonary hemorrhage.

OBJECTIVETo investigate the effect of Shenfu injection (SF) in postoperative recovery after abdominal surgery.

METHOD150 patients were randomly divided into control group (75) and SF group (75). The efficacy were evaluated with the time of passage of gas by anus, information of wound healing, blood routine, blood coagulaton function, liver function. Changes recovery factor, immune index and hemorheological index were detected too.

RESULTThe time of passage of gas by anus in SF group was significantly shorter than that in control group. Blood routine, blood coagulaton function, liver function showed no significant difference in the two group of preoperative and postoperative. Whole blood viscosity, blood reduced viscosity and plasma fibrinogen viscosity in SF group were significantly lower than that in control group after operation. IgG and IgA in SF group was significantly higher than that in control group after operation. IgG and CD4+/CD8+ in control group was significantly higher after operation than that in before operation. Among tissue damage plerosis correlation factor, the blood levels of superoxide dismutase (SOD) in SF group and control group is significantly lower than that in preoperation (P < 0.05), SOD in SF group was significantly higher than that in control group after operation. The blood levels of malondialdehyde (MDA) in SF group and control group is significantly higher than that in preoperation (P < 0.05). MDA in SF group was significantly lower than that in control group after operation. Whole blood viscosity, blood reduced viscosity and plasma fibrinogen viscosity in control group after operation were significantly higher than that before operation.

CONCLUSIONSF can stimulate the immune system and reduce the blood viscosity. It is contribute to the patients' rehabilitation.

OBJECTIVENeonatal asphyxia is one of the main causes for the acute respiratory distress syndrome (ARDS) in full-term newborns. Now it is believed that the reduced amount and abnormal function of pulmonary surfactant due to various causes is a major factor leading to acute lung injury. This study aimed at using an intrauterine acute ischemic-hypoxia rat model and investigating the effect of intrauterine acute ischemic-hypoxia on the expression of surfactant protein A (SP-A) and surfactant protein B (SP-B) in neonatal rat lungs.

METHODSThe rat model of acute intrauterine ischemic-hypoxia was established by ligating the unilateral uterine horn vessels of Wistar rats at the 21st gestational day. While the rat pups from the other side of the uterus, of which the uterine horn vessel was not ligated, were the sham-operation group. Rat pups were delivered by cesarean section at the 20, 30 and 40 min following the ischemic-hypoxia insult. The rat pups delivered by cesarean section from the gestation of 21 days were the normal control group. There were 42 rat pups and 6 pups in each group in this study. The distribution of SP-B protein in the neonatal rat lungs of different period of ischemia was examined by using SABC method. The average gray value of SP-B staining in type II alveolar epithelial cells were measured by Universal Imaging Porporation with Meta Morph software. The reverse transcription polymerase chain reaction (RT-PCR) was performed to quantitate the expression of SP-A and SP-B mRNA.

RESULTSFollowing the intrauterine acute ischemic-hypoxia, the numbers of type II alveolar epithelial cells with the positive SP-B staining were markedly declined. The average gray values at the 20, 30 and 40 min after the ischemia were 78.89 +/- 1.08, 79.69 +/- 0.13 and 80.00 +/- 0.63, respectively, which increased significantly compared with the normal control group (76.13 +/- 0.43, P < 0.01). The expression of SP-A and SP-B mRNA was weak following the ischemic-hypoxia insult. The relative amounts of SP-A (1.16 +/- 0.06, 1.14 +/- 0.01 and 1.13 +/- 0.04, respectively) and SP-B (0.81 +/- 0.02, 0.78 +/- 0.02 and 0.79 +/- 0.04, respectively) at the 20, 30 and 40 min after the ischemia were reduced significantly compared with controls (1.27 +/- 0.09 and 0.89 +/- 0.06, respectively, P < 0.05 and < 0.01) and reduced gradually following the prolongation of the insult. There were no significant differences (P > 0.05) between the normal and sham operation control groups on the expressions of SP-B protein as well as the SP-A and SP-B mRNA.

CONCLUSIONThe reduced synthesis of SP-B protein and the reduced expression of SP-A and SP-B mRNA might be caused by intrauterine acute ischemic-hypoxia, which may support theoretically the early application of pulmonary surfactant including SP-A and SP-B for treating the lung injuries of asphyxia in newborns.

OBJECTIVETo investigate the effect of Ganfukang (GFK) on connective tissue growth factor (CTGF) and focal adhesion kinase (FAK)/protein kinase B (PKB or Akt) signal pathway in a hepatic fibrosis rat model and to explore the underlying therapeutic molecular mechanisms of GFK.

METHODSFifty SD rats were randomly divided into five groups as follows: the control group, the model group (repeated subcutaneous injection of CCl4), and the three GFK treatment groups (31.25, 312.5, and 3125 mg/kg, intragastric administration). Reverse transcriptase-polymerase chain reaction (RT-PCR), Western blotting, and immunohistochemistry were used to examine the expression of CTGF, integrin α5, integrin β1, FAK/Akt signal pathway, cyclinD1, and collagen in the different-treated rats.

RESULTSGFK attenuated the up-regulation of CTGF, integrin α5, and integrin β1 in hepatic fibrosis rats and suppressed both the phosphorylation of FAK and the phosphorylation of Akt simultaneously (P<0.01). At the same time, the expression of cyclinD1, collagen I, and collagen III was decreased by GFK significantly (P<0.01).

CONCLUSIONSCTGF and FAK/Akt signal pathway were activated in the CCl4-induced hepatic fibrosis rats, which contribute to increased expression of cyclinD1 and collagen genes. The mechanisms of the anti-fibrosis activity of GFK may be due to its effects against CTGF and FAk/Akt signal pathway.
