To study the effects of alkaloids from Coptidis Rhizoma on low-density lipoprotein receptor (LDLR) mRNA expression and antihyperlipedemic levels. The LDLR mRNA expression were detected by real time fluorescence quantitative PCR, and the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-c) and high-density lipoprotein cholesterol (HDL-c) in serum were measured at the first and last examination. The results show that, after the drug treatment, compared with the model group, each drug group showed a lipid-lowering effect. Especially, coptisine, palmatine, jatrorrhinze were significantly reduced TC, TG, LDL-c (P < 0.05, P < 0.01), and increased HDL-c (P < 0.01). In addition, they also increased mRNA expression of the LDLR in liver and HepG2 cells. The results showed that alkaloids from Coptidis Rhizoma can regulate lipid metabolism disorder, and coptisine have the best lipid-lowering effect.

Objective To study the indication and clinical application of lateral neck incision for the removal of cervical esophageal foreign bodies. Methods From January 1999 to January 2009, 2189 cases esophageal foreign bodies were treated. The clinical data of 137 cases (6. 25% ) with lateral neck incision were retrospectively analyzed. In these 137 cases, 114 cases were over 16-years-old (adult group) , while 23 cases were under 16-years-old( children group). In adult group, 67 cases(58. 8% ) had esophageal perforation (esophageal perforation with neck abscess 29 cases, esophageal perforation without neck abscess 38 cases); 47 cases did not have esophageal perforation ( impacted foreign body without neck abscess 40 cases, foreign body with esophageal abscess 7 cases). In children group, 19 cases (82.6%) had esophageal perforation including 15 cases with neck abscess; 4 cases without esophageal perforation, 3 cases had esophageal abscess and one case without abscess but of huge foreign body. Results All 137 patients with foreign body were cured through lateral neck incision. Nineteen cases(13. 9% ) had hoarseness and recovered in 3 months. Five adult patients had post-operative cicatrical stricture of the esophagus, but it was mild and completely recovered by the treatment of dilatation in 3 to 11 months. Nine adult patients with esophageal perforation were cured by secondary suture, the remaining esophageal perforation cases were healed by first intention. One case with common carotid artery impairement by the foreign body was successfully treated by carotid artery ligation without hemiplegia, aphasia and other sequelae. Two cases had cardiopulmonary arrest, 2 cases had febrile convulsions and 1 case had acute respiratory failure, 5 cases had septic shock, all these patients were effectively controlled and cured. Seven of the 9 cases with tracheotomy had the tracheal tube removed during hospitalization; 1 of the two obese patients had the extubation 3 months after the discharge and the other one still had the tube. All esophageal perforation cases in children group had primary healing by perforation apposition suture. Four of the 5 children had successful tracheotomy decannulation, one child had extubation by 2 months through continuously reduced tracheal tube model. Conclusion Penetrating esophageal foreign body and neck abscess were indication of the lateral neck incision, and positive prevention and cure the complications of lateral neck incision could achieve good curative effect .

OBJECTIVETo study the distribution of mutations of UDP-glucuronosyltransferase 1A1 (UGT1A1) gene and its relationship with hyperbilirubinemia among neonates with hyperbilirubinemia of Guangxi Heiyi Zhuang nationality.
METHODSTotal genomic DNA was extracted from the blood of 100 neonates with hyperbilirubinemia (case group) and 100 neonates without hyperbilirubinemia (control group), all of whom were selected from Guangxi Heiyi Zhuang population. TATA box and all exons of UGT1A1 gene were amplified by PCR and directly sequenced.
RESULTS(TA)7 insertion mutation in TATA box, G71R missense mutation in exon 1, and 4 single nucleotide polymorphisms (SNPs) (rs199539868, rs114982090, rs1042640 and rs8330) in exon 5 were observed. The allele frequency of G71R mutation in the case group was significantly higher than that in the control group (P<0.01). There were no significant differences in the genotype distribution and allele frequency of TATA box mutation and SNPs (rs1042640 and rs8330) between the two groups (P>0.05). The logistic regression analysis showed that the odds ratios (95% confidence intervals) of UGT1A1 TATA box mutation, G71R mutation, and SNPs (rs1042640 and rs8330) associated with the development of neonatal hyperbilirubinemia were 0.846 (0.440, 1.629), 3.932 (1.745, 8.858), 0.899 (0.364, 2.222), respectively.
CONCLUSIONS(TA)7 insertion mutation and G71R missense mutation of UGT1A1 gene are common mutation types in neonates with hyperbilirubinemia of Guangxi Heiyi Zhuang nationality. Four SNPs (rs199539868, rs114982090, rs1042640, and rs8330) was first reported in China. UGT1A1 G71R missense mutation is a risk factor for hyperbilirubinemia in neonates of Guangxi Heiyi Zhuang nationality.

OBJECTIVETo investigate whether mammalian target of rapamycin (mTOR) kinase was abnormally activated in maldeveloped balloon cells and dysmorphic neurons of focal cortical dysplasia (FCD) with refractory epilepsy.
METHODSA total of 12 archival cases of FCD typeIIwith medically intractable epilepsy treated between 2008 and 2010 were retrieved. Perilesional brain tissue was used as control specimens (n = 8). The expression of phosphorylated p-AKT (Ser473), p-mTOR (Ser2448) and p-P70S6K (Thr389) was investigated by imunocytochemistry.
RESULTSThe expression of p-AKT (Ser473), p-mTOR (Ser2448) and p-P70S6K (Thr389) was found in meldeveloped balloon cells and dysmorphic neurons of FCD. A weak stain in a small amount of pyramid neurons was also found in the control group.
CONCLUSIONAbnormal activation of mTOR in maldeveloped balloon cells and dysmorphic neurons of FCD may be a key molecular mechanism underlying the histological changes and repeated seizures.

OBJECTIVETo investigate the risk factors related to post-asphyxial multiple organ dysfunction (PA-MOD) in neonates.
METHODSA total of 397 neonates with birth asphyxia were enrolled from January 2009 to December 2010.The patients were divided into PA-MOD group (n=179) and non-PA-MOD group (n=218). The risk factors of PA-MOD were retrospectively studied.
RESULTSMultivariate logistic regression analysis showed that severe asphyxia, fetal distress, abnormal labor, and decreased amniotic fluid were the risk factors for PA-MOD among the neonates. Spearman rank correlation analysis showed that the number of the involved organs increased along with the increase of age at admission (P<0.05) and with the decrease of gestational age and birth weight (P<0.05).
CONCLUSIONSThe efforts should be made to enhance perinatal care for neonates, especially for preterm infants and low-birh-weight infants, to decrease the incidence of MOD.
