Objective To observe the clinical application of extraperitoneal cesarean section(ECS) plus forceps vs transperitoneal cesarean sections(TCS) in repeated cesarean section.Methods 98 multiparous women with scar uterus for elective repeated cesarean sections were recruited retrospectively,47 cases for ECS plus forceps(group A),and 51 cases for TCS(group B).The multiparous women with hyperglycemia not controlled,severe preeclampsia,heart disease,placenta previa,premature rupture of membrane,a history of ＞ 1 cesarean section,myoma and/or ovarian neoplasm were excluded.Results Skin incision to baby delivery time and total operation time of group A were (7.7 ± 2.8) min and (42.8 ± 9.7) min,respectively,which were significantly shorter than (9.3 ± 3.2) min and (47.6 ± 9.4) min of group B,(t =2.700,2.497,P =0.008,0.014).There was significant difference in blood loss volume during the operation and postoperative 2 hours,which was (310.4 ± 106.3) mL,(365.3 ± 142.8) mL respectively(t =2.142,P =0.035).The Visual Analog Scale for pain (VAS pain) was (2.8 ± 1.8) in group A and (4.1 ± 1.9) in group B,respectively (t =3.252,P =0.002).The gastrointestinal function recovery mean time of group A was significantly shorter than that of group B (12.5 h versus 16.0h,t =2.771,P =0.007).And the postoperative febrile morbidity was significantly lower in group A than in group B(8.5％ versus 25.5％ ;x2 =4.918,P =0.033).The patients with chronic pelvic pain followed up after operation was 3 versus 12,and the difference was significant (x2 =5.143,P =0.026).There were no differences in neonatal Apgar score at 1 minute,birth asphyxia and wound healing rates.Conclusion ECS plus forceps can be safely used for repeated cesarean section,with the advantages of less operation time,less bleeding volume,lower postoperative morbidity,and fewer complications than TCS.

Repetitive(repetitive extragenic palindromic,REP,and enterobaterial repetitive intergenic consensus,ERIC) sequences in conjunction with polymerase chain reaction technique(REP and ERIC PCR) were used to fingerprint the genomes of 27 isolates of indigenous soybean rhizobia from Xinjiang.The indigenous soybean rhizobia in Xinjiang can be clustered into relative genetic similarities of approximately 0.5,of which one group mainly includes all slow-growing rhizobia,another mainly includes all fast-growing stains. REP and ERIC PCR analysis demonstrate a substantial genetic variability within members of Xinjiang indigenous soybean rhizobial populations, which reveals that genetic similarities have certain geographical correlation, and isolates from the same site have relative higher similarities.The results show that REP and ERIC PCR analysis give effective means in genetic diversity and population structure analysis of soybean rhizobia.

OBJECTIVETo study the effect of Chinese composite recipe in treating mycotic infection.

METHODSThe growth condition of 7 kinds of fungi cultured on the media containing composite agastache lotion (CAL, consisted of 5 Chinese drugs) of different concentration was observed. Result showed that CAL could inhibit 7 kinds of fungi. Based on the above anti-fungus test, 110 patients with skin tinea or genital candidiasis were treated separately with CAL, western medicine and combined (CAL and western) medicines, the therapeutic effects of the 3 groups were observed and compared.

RESULTSThe therapeutic effect in patients treated with combined medicine was significantly better than that in the other two groups (P < 0.05).

CONCLUSIONCombined use of CAL and western medicine could enhance the cure rate in treating skin tinea and genital candidiasis. Attention should be paid on studying Chinese anti-fungal agents.

OBJECTIVETo assess the association between brain-derived neurotrophic factor (BDNF) gene Val66Met polymorphism and clinical characteristics of first episode schizophrenia in a Chinese Han population.

METHODSGenotyping of BDNF Val66Met polymorphism was carried out for 135 schizophrenic patients and 483 healthy controls with TaqMan probe technology. The patients' psychotic symptoms were assessed using the positive and negative syndrome scale (PANSS).

RESULTSA significant difference was found in genotype distribution and allelic frequency of the Val66Met polymorphism between the two groups (P< 0.01). In patients, Met homozygotes had a significantly higher score in anxiety/depression factor, cognitive factor and total score of PANSS than Val carriers.

CONCLUSIONBDNF gene Val66Met polymorphism is associated with the pathogenesis of schizophrenia. The Met/Met genotype of BDNF Val66Met variant may be a risk factor for symptoms in first episode schizophrenia patients.

An expression plasmid carrying anthrax protective antigen (PA) gene was constructed, which has an OmpA signal sequence attached to the 5' end of PA gene. The plasmid was transformed into E. coli and induced to express recombinant PA (rPA) . The recombinant protein, about 10% of the total bacterial protein in volume, was secreted to the periplasmic space of the cell. After a purification procedure including ion-exchange, hydrophobic interaction chromatography, and gel filtration, about 15 mg of 95 % pure rPA was obtained from 1-liter culture. The bioactivity of rPA was proved by in vitro cytotoxicity assay. The polyclonal antiserum from rabbits immunized with rPA could inhibit the action of anthrax lethal toxin in vitro, which suggests that antibodies against rPA can provide high passive protection against anthrax. The results reported here may be helpful to develop a safe and efficacious recombinant PA vaccine against anthrax.

OBJECTIVETo explore Chinese medical syndrome distribution features of Japanese encephalitis (JE), and to analyze its correlation between syndromes and features of etiologies and pathogeneses.

METHODSRecruited were 277 patients with confirmative diagnosis of JE from Wuhan Medical Treatment Center, Children's Hospital Affiliated to Chongqing Medical University, Fifth People's Hospital of Guiyang City, Hangzhou Sixth People's Hospital, and Chengdu Hospital of Infectious Diseases between July to September 2012. Chinese medical syndrome distribution features were summarized from their general materials and detailed records of clinical data, including medical history, symptoms and signs, tongue fur, and pulse figures.The frequency of symptoms and signs was calculated according to mild, ordinary, severe, extreme severe degrees. The distribution of Chinese medical syndromes was summarized. And its correlation between syndromes and features of etiologies and pathogeneses were analyzed.

RESULTSAfter clustering analysis, Chinese medical syndromes of JE could be categorized as four groups: toxicity accumulation in Fei and Wei syndrome (TAFWS), brain collateral impaired by poison syndrome (BCIPS), depression of toxicity in the pericardium syndrome (DTPS), exhaustion of yin and yang syndrome (EYYS). BCIPS and DTPS were dominated, accounting for 74.0% (205 cases). The main causes covered evil of summer heat [accounting for 92.42% (256/277 cases)], heat [accounting for 87.73% (243/277 cases)], and toxin [accounting for 99.64% (276/277 cases)].

CONCLUSIONSThe four Chinese medical syndrome types of JE met Chinese medical clinical features of encephalitis. It is induced by infestation of dampness-heat, resulting in toxicity accumulation in Fei and Wei, brain collateral impaired by poison, depression of toxicity in the pericardium. Yin fluid and blood is exhausted as time goes by. Qi and yin are impaired to form intermingled deficiency and excess, and finally causing exhaustion of yin and yang.

Objective To investigate teratogenicity on the zebrafish embryo and genetoxicity induced by Sodium Pentachlorophenate (NaPCP),and to provide suggestions for protecting the environmental safety and human health. Methods Zebrafish embryonic development test,p53 gene in zebrafish eggs mutagenicity test,Vicia Faba Micronucleus Test and Ames test were used in the studies.Results The results of zebrafish embryonic development test showed that NaPCP increased embryonic 120 hpf teratogeny rates and 120 hpf death rates and decreased embryonic 120 hpf hatching rates in concentration of 0.5 -2.5 μL/L,with significant teratogenic effect on the embryo.The rates of embryo abnormity increased with the exposure time and concentration.Sequence analysis showed that NaPCP exposure group zebrafish p53 gene had mutated at the concentration of 0.4 μL /L.The base substitution of AAT→AAG at codon 49,ACA→ACG at codon 87 and GCG→GCA at codon 158 were detected by PCR -directed sequencing.This may result in the Asn→Lys of expressed p53 protein.As compared with control group,0.2 mg/L,1.0 mg/L dosage of NaPCP could induce an extremely significant increase in micronucleus frequency of vicia faba root tip cells and had a certain dose -effect relationship.Ames test was negative.Conclusion NaPCP could delay embryonic development and even cause embryonic lethality and induce abnormality in zebrafish.NaPCP had certain genetoxicity.
