Objective To discuss the growth suppressing, apoptosing effect of new type tumor-supressor gene-p33ING1 in stomach cancer cell strain, and to explore new strategies and methods in tumor therapy. Methods The PCDNA3/p33ING1 nuclear expressing microsome was constructed, p33ING1 and wt-p53 were implanted to human stomach cancer cell both and to evaluate the effect of p33ING1 and p53 toward stomach cancer cell and synergism between them. Results The PCDNA3/p33ING1 nuclear expressing microsome was successfully constructed. The human stomach cancer cell strain SSCG-7901 under implantation of p33ING1 and wt-p53 showed a significant decrease in cell growth, the coupling time was delayed, DNA synthetic phase was shortened and G0/G1 phase prolonged. The cell collapse increased. Conclusions Despite of the tumor-inhibiting effect and biochemical activation of p33ING1, it also plays a role with p53 gene in controling growth of stomach cancer cell, inducing cell collapse and hampering cell proliferation cycle. P33ING1 and p53 are synergistic to each other.

The aim of this study is to develop a convenient and effective method for the identification of heparin from pigs (include Sus scrofa domestica Brisson and Sus scrofa riukiuanus). Based on sequences of D-loop region of pigs and the other animals, two pairs of highly specific primers were designed for distinguishing heparin of pigs from other animals. The primers were employed to amplify D-loop region of DNA templates extracted from pig and seven other animal species that amounted to 49 samples. AS-PCR (allele-specific PCR) and ARMS (amplification refractory mutation system) were all suitable for fast identification of heparin from pig with anneal temperature at 54-56 degrees C in AS-PCR and with wider anneal temperature in ARMS,at 52-58 degrees C. An about 170 bp DNA fragments were amplified from separately pigs and whereas no DNA fragment was amplified from other samples under the same reaction condition.

OBJECTIVETo explore regional anatomy of fasciae and spaces related to laparoscopic right hemicolectomy (LRC).
METHODSSeven cadavers and 49 patients undergoing LRC for cancer were observed. Computed tomography (CT) images of patients and healthy individuals were reviewed.
RESULTSBetween ascending mesocolon and prerenal fascia (PRF), there was a right retrocolic space (RRCS), which communicated in all directions. Anterior, posterior, medial, lateral, cranial, and caudal boundaries of the RRCS were ascending mesocolon, PRF, superior mesenteric vein, peritoneal reflexion at right paracolic sulcus, inferior margin of transverse part of duodenum, and inferior margin of the mesentery root, respectively. Between transverse mesocolon and pancreas and duodenum, there was a transverse retrocolic space (TRCS), which was bounded cranially by root of transverse mesocolon. On CT images of healthy individuals, PRF was noted as slender line of middle density, continuing to transverse fascia, and the retrocolic spaces were unidentifiable. For patients with right colon cancer, PRF and right retrocolic space might be easier to be identified.
CONCLUSIONSThe RRCS and the TRCS are natural surgical spaces. The PRF is natural surgical plane in LRC for cancer.

To apply chitooligosaccharide in the preparation of baicalin compound, in order to increase the drug dissolution in vitro, and investigate the basic property of the compound. Baicalin-chitooligosaccharide compound was prepared by using the solvent method. The structure and physicochemical properties of compound were analyzed by using differential scanning calorimetry (DSC), scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and infrared vibrational spectrum (IR), and its dissolution behavior was also investigated. The results showed that the compound prepared at baicalin-chitooligosaccharide molar ratio of 1 : 1 could significantly improve the dissolution of baicalin. The results of DSC and XRD analysis suggested that baicalin may exist in an amorphous state. IR results indicated the interaction between baicalin and chitooligosaccharide. The baicalin-chitooligosaccharide compound could significantly improve dissolution in vitro of drug.

In order to affirm the cardioactive components in Fuzi, we identified a group of aminoalcohol- diterpenoid alkaloids in Fuzi using ultra high-performance liquid chromatography coupled with electrospray ionization mass spectrometer (UPLC-ESI-MS) method. Among a total of forty-one isolated ingredients, thirteen major aminoalcohol-diterpenoid alkaloids were identified by comparing their retention times and MS spectra with those of the reference substances. Moreover, Fuzi samples from different places of origin and with different processing methods were examined and their components displayed a pattern of high similarity, though the relative abundance varies probably due to their different processing methods. Furthermore, the cardiac effect of each identified alkaloid was individually evaluated using the isolated bullfrog heart perfusion experiment. Among the thirteen aminoalcohol diterpenoid alkaloids tested, six of them significantly enhanced the amplitude rates. Taken together, we affirm that the cardioactive components in Fuzi are aminoalcohol-diterpenoid alkaloids, shedding light on future studies of the mechanisms and development of these cardioactive compounds.

Through potted inoculation test at room temperature and indoor analysis, the photosynthetic parameters and physiological and biochemical indexes of Paris polyphylla var. yunnanensis were observed after 28 arbuscular mycorrhizal (AM) fungi were injected into the P. polyphylla var. yunnanensis growing in a sterile soil environment. The results showed that AM fungi established a good symbiosis with P. polyphylla var. yunnanensis. The AM fungi influenced the photosynthetic parameters and physiological and biochemical indexes of P. polyphylla var. yunnanensis. And the influences were varied depending on different AM fungi. The application of AM fungi improved photosynthesis intensity of P. polyphylla var. yunnanensis mesophyll cells, the contents of soluble protein and soluble sugar, protective enzyme activity of P. polyphylla var. yunnanensis leaf, which was beneficial to resist the adverse environment and promote the growth of P. polyphylla var. yunnanensis. Otherwise, there was a certain mutual selectivity between P. polyphylla var. yunnanensis and AM fungi. From the comprehensive effect of inoculation, Racocetra coralloidea, Scutellospora calospora, Claroideoglomus claroideum, S. pellucida and Rhizophagus clarus were the most suitable AM fungi to P. polyphylla var. yunnanensis when P. polyphylla var. yunnanensis was planted in the field.

Objective To study antibiotic resistance phenotypes and genotypes of extended spectrum ?-lactamases (ESBLs) and AmpC ?-lactamase-producing Klebsiella oxytoca isolated from specimens of respiratory tract in children.Methods Bacterial isolates were identified by API or VITEK32. Agar dilution was used for antibiotic susceptibility test,and ESBLs and AmpC were detected by confirmatory test recommended by CLSI/NCCLS and by 3-aminophenylboronic acid (APB) disk potentiation test, respectively.Microarray was used to determine the genotypes of ESBLs and AmpC ?-lactamases.Genotypes of Klebsiella oxytoca were determined by enterobacterial repetitive intergenic consensus (ERIC)- PCR.Results ESBLs were positive in 129 out of 165 isolates (78.2%).Both ESBLs and AmpC ?- lactamases were positive in 16 out of 165 isolates (9.7%).AmpC ?-lactamase alone producer was not detected in term of phenotype and genotype.CTX-M was the most common type of ESBLs and DHA was the only type of AmpC ?-lactamase in these isolates.Most antibiotic resistant strains of Klebsiella oxytoca possessed the same genotype by ERIC-PCR.Although all strains were susceptible to carbpenem,Klebsiella oxytoca with ?-lactamases were more resistant to other antibiotic agents than those without ?- lactamases.Conclusions There is high prevalence of ESBLs production among Klebsiella oxytoca isolated from children in Urumqi.The main genotypes of ESBLs and AmpC ?-lactamases are CTX-M and DHA.
