OBJECTIVETo analyze the relationship between Chinese medical constitutions and chemotherapy-induced leucopenia (CIL) of primary breast cancer patients.

METHODSTotally 306 breast cancer patients undergoing adjunctive chemotherapy for the 1st time, and effective 291 breast cancer patients were recruited in this study.Nine Basic Constitutional Scale was used before first chemotherapy. Chinese medical constitutions were classified and quantitatively scored. The highest grading for any item of adverse reactions in each case during the whole chemotherapy course was recorded after chemotherapy. Data were statistically analyzed using SPSS16.0.

RESULTSThere was no significant difference in CIL between different chemotherapy regimens and various Chinese medical constitutions of breast cancer patients (P > 0.05). Yang deficiency constitution is one risk factor for CIL. The higher the score of yang deficiency constitution, the more severe the CIL.

CONCLUSIONSYang deficiency constitution was correlated with the degree of CIL. The higher the score of yang deficiency constitution, the greater the risk of III-IV grade CIL in breast cancer patients.

OBJECTIVE: To investigate the correlation between the polymorphism of genotype of site-1296 in alpha2A-AR receptor gene and the susceptibility of vestibular function. METHOD: Ninety-four blood samples were collected from pilot cadets, consisting of susceptible and tolerance groups to vestibular function. Genomic DNA was isolated, and the coding region of alpha2A-AR receptor gene was amplified by polymerase chain reaction (PCR). The PCR products were analyzed by gene sequencing. Gene frequency was calculated, and, the coincidence between the polymorphism of alpha2A-AR receptor gene in the groups and Hardy-Weinberg balance was evaluated. The allele frequency of the two groups was compared by Chi square test. RESULT: G/C polymorphism was existed in Site-1296 of alpha2A-AR gene regulation zone, including GG, GC, CC. The express of GG Genotype in susceptible group exceeded that of the other group. There were significance differences in both genotype constituent ratio and alleles frequency of the two groups. CONCLUSION The polymorphism of genotype of site-1296 in alpha2A-AR receptor gene is possibly correlated with the susceptibility to vestibular function.

PURPOSE: The purpose of this study was to observe the effects of metformin on human esophageal cancer cell and to investigate its possible mechanisms. MATERIALS AND METHODS: Cell viability was detected by using a Cell Counting Kit-8, while cell cycle and apoptosis were assessed by flow cytometry and western blot was used to measure the expression of the related proteins. RNAi was used to knockout pyruvate kinase muscle isozyme 2 (PKM2). An Eca109 tumor model was established to evaluate the antitumor effect in vivo. Immunohistochemistry was determined based on the expression of PKM2 and Bim in tumor tissues. Tunnel was used to assess tumor cell apoptosis. RESULTS: Esophageal cancer cells viability was reduced after metformin treatment. The cell cycle was arrested in the G0/G1 phase, apoptosis was induced, caspase 3 was activated, caspase 9 was downregulated, and the pro-apoptotic protein Bim increased. Further study revealed that metformin could suppress the expression of insulin-like growth factor 1 receptor and its downstream proteins, phosphoinositide 3-kinase (PI3K), protein kinase B (AKT/PKB), phosphorylation of AKT (pAKT), mammalian target of rapamycin (mTOR), p70S6K, and PKM2. Insulin-like growth factor 1 partly reversed metfromin-induced apoptosis and attenuated the repression effect of metfomin to PI3K, pAKT, and PKM2. Knockout PKM2 resulted in the activation of caspase 3, down-regulation of caspase 9, and increased expression of Bim. In the Eca109 xenograft model, metformin significantly reduced tumor growth. Furthermore, we found that metformin treatment increased the rate of apoptosis, down-regulation of PKM2, and up-regulation of Bim in tumor tissues. CONCLUSION: Metformin restrained esophageal cancer cell proliferation partly by suppressing the PI3K/AKT/mTOR pathway.

We used metabolomics to investigate the ability of a traditional Mongolian medicine called modified Tabusen-2 (MT-2) to improve kidney yang deficiency (KYD) in rats. All animal experiments were conducted under the guidance and standards of the Medical Ethics Committee of Inner Mongolia Medical University. SD rats were divided into 6 groups of six rats: a normal group, a model group, Jinkuishenqi pill administration group (1.26 g·kg^-1), and MT-2 administration in high-, medium- and low-dose groups (1.512, 0.756, and 0.378 g·kg^-1). KYD was established by intramuscular injection of hydrocortisone (HC) and biochemical indicators and clinical characterization was used to confirm that KYD was established. All groups received intragastrically administered drug (Jinkuishenqi pill or MT-2) or saline. Serum from each group was collected after 8 weeks and analyzed by UPLC-Q-exactive-MS to measure various biochemical indicators. The biomarkers affected by MT-2 were identified and the metabolic pathways of KYD regulated by MT-2 were analyzed by metabolomic analysis. The results show that MT-2 can decrease serum creatinine (Cr) in KYD rats and significantly increase (P<0.05) the content of thyroid stimulating hormone (TSH) and luteinizing hormone (LH). In serum samples, 38 biomarkers such as corticosterone, L-phenylalanine, and DL-tryptophan were measured as possible indicators for disease development in KYD rats. MT-2 lowered 18 biomarkers of KYD, including corticosterone, deoxycorticosterone, and L-phenylalanine, and altered 13 related metabolic pathways including phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism and steroid hormone biosynthesis, resulting in an overall improvement in KYD. MT-2 appears to be important in improving KYD in rats mainly by regulating metabolites such as amino acids, steroids and lipids.

Objective The factors influencing the dose distribution of intracavitary brachytherapy for moderately advanced and advanced uterine cervical cancer was studied.Methods Ninty-five patients with cervical cancerⅡ～Ⅲb who received radical radiation therapy in our department from Aug,2004 to Nov,2005,were treated with after-loading brachytherapy using,first,the self-designed“Mutipurpose Hori- zontal Transit Table”(MPHTT) for locating and treatment before the intracavitaray brachytherapy proper. The deviation of isodose curve based on A-B reference system,and the dose of deviation was defined by measuring in a practical standard phantom.Results There were significant influence on the deviation of i- sodose curve in pathology and para-metrial infiltration of cervical cancer and operating skill,but negative to clinical stage.The degree of deviation of isodose curve could not be lowered with the increase in sessions of intracavitary brachytherapy.Conclusions It is necessary to perform the locating,by use of mphtt,before the proper brachytherapy for patients with cervical cancer,not only for the identification of the deviation of i- sodose curve,but also to provide the evidence for revising the plan for dose adjustment of conformal radiation therapy in the pelvic cavity.

OBJECTIVE: To study the morphological characteristics of femurs of adult human and 11 kinds of adult animals from cattle, horses, pigs, goats, sheep, dogs, cats, rabbits, geese, ducks, chickens, and to establish an effective species identification method among various species. METHODS: The 4 cm mid-diaphyseal segment of the femur from adult human (older than 20 years old) at autopsy was obtained. Addi-tionally, the 4 cm ones from 11 kinds of adult animals were obtained. After decalcification, all femurs were made into slices, and then were observed by optical microscope. The 25 indexes were selected and analyzed by step discriminant analysis according to differences between human and mammal, human and poultry, and human and 11 kinds of animals. RESULTS: The histological structure of bone mineral density of middle part of femur had obvious characteristics among the species. And the morphology and number of osteon showed the trend of obvious biological evolution. There were 11 indexes with significant differences between human and 11 kinds of animals to establish some mathematical models to discriminate all species. The correct discrimination rate was 96.3% between human and mammal. The correct discrimination rate was up to 100% between human and poultry, and was 89.4% among human, mammal and poultry. CONCLUSION The mathematical models have good correct discrimination rate among human and the other animals, which could be applied in the practical species identification cases.

Neurogranin, a neuron-specific postsynaptic protein, has been considered to play an important role in synaptic plasticity and learning and memory. The present study aimed to investigate the effects of prenatal restraint stress on neurogranin expression in rat offspring hippocampus. Pregnant rats were given a restraint stress (3 times a day for 7 d, 45 min each time) at the late stage of gestation except that in the control group. The offspring rats were divided into four groups: female control group, male control group, female stress group and male stress group. Expression of neurogranin was determined by immunohistochemistry and Western blot. The results showed that neurogranin-positive immunostaining was detected in all areas of the hippocampus. The staining density was stronger in the CA1 and CA3 regions than that in the dentate gyrus (DG) region. Western blot assay showed that neurogranin protein level in female and male prenatal stressed offspring was significantly lower than that in the controls (P<0.01). Neurogranin level was significantly lower in the female stress group than that in the male stress group, whereas there was no significant gender difference in the control group. Immunohistochemical data further confirmed these results. The present study provides evidence that prenatal restraint stress induces gender-dependent decrease in neurogranin expression in the offspring hippocampus. The prenatal restraint stress-induced decrease in neurogranin expression in the hippocampus might be associated with the deficit in spatial learning and memory reported previously.
