Objective To study the protective effect and its mechanism of anti-tumor necrosis factor-?antibody (TNF-? Ab) on lung injury after cardiopulmanary bypass(CPB).Methods Twenty-eight healthy rabbits were selected and randomly divided into four groups:group Ⅰ only received open chest operation;groups Ⅱ-Ⅳ underwent CPB.In the group Ⅳ,rabbit TNF-? Ab (2 400 pg/kg) was dropped into the intracheal tube before operation and just after releasing the aortic clamp.Saline was given to the group Ⅲ in- stead.Blood neutrophils count,TNF-?,MDA from the right and left atrium in the four groups were determined perioperatively.Water volume,TNF-? mRNA,TNF-? protein,apoptosis and pathomorphological changes were measured in the lung tissues.Results TNF- ? Ab can restrain leukocyte accumulation,reduce releasing of TNF-? and MDA in the lung.It can also reduce the occurrence of apop- tosis and attenuate pathomorphological changes in the lung tissue.However,it cannot reduce the secretion of TNF-? at the transcrip- tion level and protein level.Conclusion Intratracheal TNF-? Ab administration has markedly protective effect on lung injury after CPB.

OBJECTIVETo compare the therapeutic effects of peripheral facial paralysis in acute stage by different interventions and explore the better treatments of peripheral facial paralysis.

METHODSOne hundred and thirty one cases of Bell's facial paralysis were randomly divided into three groups. In acupuncture group (44 cases), Dicang (ST 4), Jiache (ST 6), Hegu (LI 4), Yangbai (GB 14) and Taiyang (EX-HN 5), etc. were applied; in electroacupuncture group (45 cases), the selection of acupoints and needling method were same as those in acupuncture group, and the electroacupuncture therapy was applied on Dicang (ST 4), Xiaguan (ST 7), Yangbai (GB 14) and Taiyang (EX-HN 5) in acute stage; in medication and acupuncture group (42 cases), Prednisone and Acyclovir were taken by oral administration, Vitamin B1 and Vitamin B12, were applied by intramuscular injection in acute stage, and acupuncture was applied by the way which was same as that in acupuncture group during quiescent and recovery stages. The curative effects were evaluated by House-Brackmann Grading Scale, and the failed rates were observed by follow-up after one and three months.

RESULTSThe cured and markedly effective rates were 79.6% (35/44), 93.4% (42/45) and 78.6% (33/42) respectively in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.05). The cured rates above tympanichord were 54.2% (13/24), 85.2% (23/27) and 48.0% (12/25) in acupuncture group, electroacupuncture group and medication and acupuncture group, and the result in electroacupuncture group was superior to those in acupuncture group and medication and acupuncture group (P < 0.01). There was no significant differences of cured rates below tympanichord among three groups (P > 0.05); and the failed rate in electroacupuncture group was much lower than those in acupuncture group and medication and acupuncture group by follow-up after one and three months (all P < 0.01).

CONCLUSIONThe peripheral facial paralysis is effectively treated by electroacupuncture in acute stage, and it suggests that electroacupuncture should be applied early during the acupuncture treatment of peripheral facial paralysis.

OBJECTIVENeonatal unconjugated hyperbilirubinemia is one of the most common conditions encountered by the practicing pediatricians. Although it is usually self-limited and benign, the condition is of importance because of the rare instances in which severe hyperbilirubinemia can lead to bilirubin encephalopathy or kernicterus. The uridine diphosphate-glucuronosyl transferase 1A1 (UGT 1A1) gene controls bilirubin conjugation by determining the structure of the enzyme glucuronosyltransferase, which is synthesized in the hepatocyte. In the recent years much has been learned about the relationship between UGT 1A1 gene mutation and neonatal hyperbilirubinemia. This study aimed to investigate the roles of UGT 1A1 gene mutation in the development of neonatal hyperbilirubinemia in Guangxi.

METHODSA total of 73 cases with hyperbilirubinemia and 31 healthy neonates were enrolled. UGT 1A1 G71R genotypes were identified by the (amplification refractory mutation system, ARMS) and direct sequencing method in all the neonates. To analyze the incidence of bilirubin encephalopathy, the peak (total serum bilirubin, TSB) concentration after 72 hours of age, and the possibility of TSB > 20 mg/dl of each group.

RESULTS(1) The frequencies of allele G71R were 0.1915 in this study, 0.2329 in hyperbilirubinemia group vs. 0.097 in healthy groups. The allele gene frequency of G71R in neonatal hyperbilirubinemia was higher than that in the normal group (P < 0.05). (2) Homozygous neonates had higher possibility to develop bilirubin encephalopathy and higher TSB concentration 72 hours after birth (28.57%, 23.12 ± 4.58) than the normal group (0%, 17.68 ± 2.69). The difference between the former two was significant (P < 0.001). (3) The TSB of the 5 neonates was > 20 mg/dl in G71R homozygous type, the odds ratio and 95%CI were 7.955 (1.349, 46.899).

CONCLUSION(1) G71R mutation gene was associated with neonatal jaundice in Guangxi region. (2) The possibility of TSB > 20 mg/dl in G71R homozygous was higher than those of the wild-type. (3) The incidence of bilirubin encephalopathy and TSB concentration after 72 hours of age for neonates who were homozygous to G71R gene were higher than the wild-type.

OBJECTIVETo study the correlation between glucose-6-phosphate dehydrogenase (G-6-PD) activities and three common mutations of G-6-PD gene G1388A, G1376T and A95G and investigate the effects of G-6-PD gene mutations on neonatal jaundice in Nanning, Guangxi.

METHODSOne hundred and twenty-four neonates from Nanning, Guangxi, with hyperbilirubinemia were enrolled. The ARMS-PCR and PCR/REA methods were used to determine G-6-PD gene mutations. G-6-PD activities were measured using the NBT method. The incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth were compared between the neonates with different genotypes and between the G-6-PD mutation and normal groups. The risk of blood serum bilirubin >340 mumol/L was evaluated by logistic regression analysis.

RESULTSOf the 124 cases, gene mutations were found in 37 cases, including G1388A (n=20), G1376T (n=14), A95G (n=4) and G1388A+A95G (n=1). Five cases (25%) showed normal G-6-PD activities in the G1388A gene mutation group and 4 (29%) had normal G-6-PD activities in the G1376T G1388A gene mutation group. All of 4 cases of A95G G1388A gene mutation showed a deficiency of G-6-PD activities. There were no significant differences in the incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth between the G1388A and G1376T G1388A gene mutation groups. The incidence of acute bilirubin encephalopathy, the peak bilirubin concentration 72 hrs after birth and the risk of serum bilirubin >340 micromol/L in the G-6-PD mutation group were not different from the normal group.

CONCLUSIONSG1388A, G1376T and A95G are common G-6-PD gene mutations in Nanning, Guangxi. The false negative results may be received when the NBT method is used for diagnosis of G-6-PD deficiency. There are similar effects on the incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth between different gene mutation groups. G-6-PD gene mutations alone may not contribute to the development of acute bilirubin encephalopathy and the changes of peak bilirubin concentration 72 hrs after birth and the risk of serum bilirubin >340 micromol/L.

Objective To determine the consumption of sugar-sweetened carbonated beverage and juice/fruit-flavored drink among residents aged 15 years and above in 2013 in Shanghai. Methods Data was extracted from the 2013 Shanghai Non-communicable Disease and Risk Factors Surveillance, in which multi-stage cluster sampling was performed.A total of 25 657 subjects aged ≥15 years across the city were selected for analysis. Results In the study, 34.42% (95%CI:32.33%-36.51%) and 37.85% (95%CI:35.37%-40.32%) of the subjects consumed sugar-sweetened carbonated beverage and juice/fruit-flavored drink in 2013 in Shanghai.The proportions declined with age (P for trend < 0.001), while increased with education level (P for trend < 0.001).They were 65.28% and 69.82% among students, which were much higher than other occupations.Men consumed more sugar-sweetened carbonated beverage than women (37.31% vs 31.37%), whereas less juice/fruit-flavored drink (36.14% vs 39.65%).Among the subjects consumed sugar-sweetened carbonated beverage (n=6 254) or juice/fruit-flavored drink (n=6 701), 52.20% (95%CI:49.41%-54.98%) and 54.04% (95%CI:51.09%-56.98%) consumed 1-3 times a week.The daily average amount of sugar-sweetened carbonated beverage and juice/fruit-flavored drink were 98.64 mL (95%CI:88.92-108.37) and 88.85 mL (95%CI:73.73-103.97), respectively, which were higher among the young (< 45 years old), male and students. Conclusion In 2013 in Shanghai, the consumption of sugar-sweetened carbonated beverage and juice/fruit-flavored drink is highly prevalent among residents aged 15 years and above, especially among the young, male, well-educated and students.Intervention should be tailored to reduce the consumption among at-risk population.

BACKGROUNDLate-onset multiple acyl-CoA dehydrogenase deficiency (MADD) is the most common type of lipid storage myopathies in China. Most patients with late-onset MADD are well responsive to riboflavin. Up to now, these patients are often treated with glucocorticoids as the first-line drug because they are misdiagnosed as polymyositis without muscle biopsy or gene analysis. Although glucocorticoids seem to improve the fatty acid metabolism of late-onset MADD, the objective evaluation of their rationalization on this disorder and comparison with riboflavin treatment are unknown.

METHODSWe performed a historical cohort study on the efficacy of the two drugs among 45 patients with late-onset MADD, who were divided into glucocorticoids group and riboflavin group. Detailed clinical information of baseline and 1-month follow-up were collected.

RESULTSAfter 1-month treatment, a dramatic improvement of muscle strength was found in riboflavin group (P < 0.05). There was no significant difference in muscle enzymes between the two groups. Significantly, the number of patients with full recovery in glucocorticoids group was less than the number in riboflavin group (P < 0.05). On the other hand, almost half of the patients in riboflavin group still presented high-level muscle enzymes and weak muscle strength after 1-month riboflavin treatment, meaning that 1-month treatment duration maybe insufficient and patients should keep on riboflavin supplement for a longer time.

CONCLUSIONSOur results provide credible evidences that the overall efficacy of riboflavin is superior to glucocorticoids, and a longer duration of riboflavin treatment is necessary for patients with late-onset MADD.

A prokaryotic expression plasmid containing VIP (vasoactive intestinal peptide) and sTNFRII(soluble tumor necrosis factor receptor II ) genes was constructed. The sTNFRII was cloned by PCR by using special primers which contained VIP gene ORF and a linker in its forward primer. The amplified fragment was inserted into the expression vector pET32a between BamHI and Hind III restriction sites. Transformed E.coli DH5 by pET32a-VIP- sTNFRIIexpressed the fusion protein. After being identified, the protein was purified by ion exchange chromatography and by hydrophobic interaction chromatography. The reconstructed protein showed high bio-activity and could be applied for further use.

Objective To observe the effects of acupuncture at "Sanyinjiao" (SP6) and "Baihui" (GV20) on behaviors and contents of monoamine neurotransmitter dopamine (DA), noradrenalin (NE) and 5-hydroxytrypamine (5-HT) in prefrontal cortex (PFC) of attention deficit hyperactivity disorder (ADHD) rats; To discuss mechanism of action of acupuncture for prevention and treatment of ADHD. Methods 4-week-old SHR rats were randomly divided into the model group, Western medicine group and acupuncture group, and WKY rats with the same age were selected as the normal control group, with 10 rats in each group. Acupuncture was applied to "Sanyinjiao" (SP6) and "Baihui" (GV20) of rats in acupuncture group for 15 min. The rats in Western medicine group was given MPH (ritalin) for gavage, and rats were treated for 4 weeks in the dark-phase. Open field test (OFT), elevated plus maze (EPM) and novel object recognition test (NORT) were conducted to evaluate the spontaneous activity, impulsivity and learning-memorial ability of rats individually at the end of treatment. Contents of DA, NE and 5-HT in PFC were detected by HPLC. Results Compared with the normal control group, all of the behavior parameters of rats in model group were significantly higher (P＜0.05), and the contents of DA, NE and 5-HT in PFC of model group were lower than those of normal control group (P＜0.05). Compared with the model group, acupuncture group showed shorter movement distance, less rearing and fewer grooming activities in the OFT; percentages of times of entering the open arms and staying duration were reduced in the total period in the EPM; preference index in the NORT was elevated (P＜0.05); the contents of NE and 5-HT in PFC of acupuncture group increased significantly (P＜0.05). Conclusion Acupuncture at "Sanyinjiao" (SP6) and "Baihui" (GV20) canreduce the spontaneous activity and impulsivity, and improve learning and memory ability of ADHD model rats, which may be related to elevated contents of NE and 5-HT in the PFC.

OBJECTIVE Glioblastoma multiforme (GBM) is the most malignant primary tumor of the central nervous system and is associated with a very poor prognosis. No further improvements in outcomes have been reported since radiotherapy-temozolomide therapy was introduced.Therefore,de-veloping new agents to treat GBM is important. This study aimed to evaluate the anti-tumor effect of evodiamine (Evo) on GBM cells, and to determine the underlying mechanisms involved. METHODS U251,LN229,HEB and PC12 cells were treated with various concentrations of evodiamine for 24 and 48 hours,cell viability was measured by MTT assay.The U251 and LN229 cells were treated with evo-diamine(0-10 μmol·L-1)for 24 h,and then stained with Hoechst 33258.An Annexin V-FITC Apoptosis Detection Kit was used to detect apoptosis in the cells.Reactive oxygen species(ROS)production was detected using dichlorofluorescein diacetate (DCFH-DA) staining. The changes in mitochondrial mem-brane potential (MMP) were assessed by JC-1 after cells were treated with evodiamine. The expres-sion levels of p-PI3K,PI3K,p-Akt,Akt,Bax,Bcl-2,p-p38,p38,p-JNK,JNK,p-ERK,ERK,Cytochrome c, Caspase-3, cleaved Caspase-3, PRAP, and cleaved PARP were measured by Western blot analy-ses. RESULTS According to MTT assay results, Evo significantly inhibited the cell proliferation in a time- and dose-dependent manner. Fluorescence microscopy and flow cytometry analyses revealed that Evo induced cell apoptosis in a concentration-dependent manner.Moreover,Evo induced reactive oxygen species (ROS) production and mitochondrial membrane potential (MMP) disruption. Finally, Evo induced apoptosis in cancer cells by suppressing PI3K/AKT signaling and inducing MAPK phos-phorylation(p38 and JNK,but not ERK)to regulate apoptotic proteins(Bax,Bcl-2,Cytochrome c,Cas-pase-3, and PARP). CONCLUSION In summary, Evo inhibits cell proliferation by inducing cellular apoptosis via suppressing PI3K/AKT and activating MAPK in GBM;these results indicate that Evo may be regarded as a new approach for GBM treatment.
