ObjectiveTo analyze the characteristics of top of the basilar syndrome (TOBS) in clinic and imaging.MethodsData of 31 TOBS cases were analyzed retrospectively.ResultsThe clinical features of TOBS patients were sudden unconsciousness or vertigo and dyskinesia of the limbs, the dismovement of the eyeballs, abnormality of the pupils, partial blindness or cortical blindness, hypesthesia, disturbance of memory and counting. CT and MRI showed multi-infarction included thalami, occipital lobe, cerebellum, midbrain, temporal lobe.ConclusionTOBS can be diagnosed accurately according to clinical features and imaging signs.

OBJECTIVEIt laid the foundation of the large sample data mining for a comprehensive summary concerning four properties theory of traditional Chinese medicine (TCM), and also provided theory clues on determination of four properties for the new resource development of TCM and the clinical use of Chinese medicine.

METHODFour properties data of 8 980 Chinese medicines from "Chinese herbal medicine (CHM)" and associated function index data were chose as data sets. Then, the IBM SPSS Clementine 14.1 data mining platform and Apriori model were adopted to mining classification-association rules, setting the minimum support threshold of rule antecedent and the minimum confidence threshold as 0.5% and 60%.

RESULT11 classification-association rules involved in warm, cold and mild natures were found.

CONCLUSIONIt was discovered that the TCM with functions of "dispelling wind-cold, warming the middle, stopping pain and expelling wind-removing dampness, tonifying kidney yang, unblocking meridians and expelling wind-removing dampness, dispelling cold to stop pain, strengthening sinews-bones and expelling wind-removing dampness" was likely warm-natured, with functions of "tonifying the lung" was likely mild-natured, and with functions of " clearing heat and drying dampness, clearing heat and purging fire, eliminating restlessness" was likely cold-natured.

OBJECTIVEIn order to provide theoretical clues and data support for the use of Chinese medicine clinical drug, experimental study of Chinese materia medica and development of new resources of Chinese materia medica, the four properties as the core, the relationships of property, flavor, channel tropism and toxicity in nature data of Chinese materia medica were analyzed.

METHODThe spearman rank correlation method was employed to analyze 8 356 Chinese drugs with characteristic of four properties from " Chinese Herbal Medicine" based on data level coding.

RESULTIt was discovered that four properties showed significant positive correlations with tastes of "pungent and sweet" , channels of "spleen" , "stomach" , "kidney" and "toxicity" , but also showed significant negative correlations with tastes of "bitter" and "light" and six channels such as "large intestine" , "heart", "bladder" , "gallbladder" , "small intestine" and "lung" (in descending order of correlation ) (P <0. 01).

CONCLUSIONIt was indicated that the more hot the Chinese medicine nature, the more possible it contained "toxicity" , tastes of "pungent" and "sweet" , and the more possible it was belong to channels of "spleen" , "stomach" and "kidney". As well, the more cold the Chinese medicine nature, the more possible it contained tastes of "bitter" and "light", and the more possible it was belong to six channels such as "large intestine", etc.

OBJECTIVETo explore the mechanism and efficiency of Changji'an (CJA) in treating irritable bowel syndrome through studying the relationship between serotonin transporter (SERT) and visceral hypersensitivity in rats.

METHODSMale SD rats were randomly divided into 4 groups: the normal control group, the model group, the high-dosage and low-dosage CJA (CJAH and CJAL) groups. Visceral hypersensitivity model was established by colorectal distension. Normal saline and different doses of CJA were administrated to rats respectively, starting from the 10th day of modeling for 10 days. After then, the abdominal withdrawal reflex (AWR) was scored for semi-quantitative estimation of visceral sensitivity, and tissues of brain and colon were harvested for detecting expressions of SERT and serotonin (5-HT) with Western blot, real-time PCR and immunohistochemistry.

RESULTSAs compared with the normal controls, in model rats, the AWR score and content of 5-HT in intestinal mucosa were higher (P < 0.05), protein and mRNA expressions of SERT in colon and nucleus raphes dorsalis (NRD) were lower (P < 0.05), but all these indexes were improved significantly after CJA treatment, either in the CJAH or CJAL group (all P < 0.05). Besides, the number of 5-HT energic neuron in the model group and CJA groups was lower than that in the normal control group (P < 0.05).

CONCLUSIONCJA has therapeutic effect for improving visceral hypersensitivity in irritable bowel syndrome by way of regulating colonic expression of SERT and content of 5-HT.

OBJECTIVETo investigate the clinical characteristics of acute myeloid leukemia patients with 3q abnormalities.

METHODSConventional cytogenetic analysis of R-banding was used to detect the abnormalities of 3q in 657 patients with acute myeloid leukemia (AML).

RESULTTwenty-four (3.7%) out of 657 patients had abnormalities of 3q, of which 3q21 or 3q26 were involved in 18 cases (75.0%); 3q21q26 abnormalities were harbored in 11 patients (45.8%), including 9 of t (3;3) and 2 cases of inv (3), of which 3 cases progressed from MDS. Ten patients presented with normal or elevated platelets and their bone marrow morphologies showed abnormal and striking proliferation of megakaryocytes. While in other 7 patients with 3q21 or 3q26, no one presented with high platelets and megakaryocytes. All 24 patients with 3q abnormalities received chemotherapies and only 4 patients achieved short-term remission with a median survival time of 6.7 months.

CONCLUSION3q21q26 anomaly is the most common karyotype in acute myeloid patients with 3q abnormalities. The patients with 3q anomaly had extremely poorer treatment outcome and prognosis.

OBJECTIVETo study the reproductive toxicity of metadoxine.

METHODSMale and female rats were given metadoxine before pregnancy and early gestation, i.e. to feed metadoxine to male rats for 60 days before copulation and continue feeding during copulation, and feed metadoxine to female rats for 14 days before copulation.

RESULTSNo significant toxic effect was observed in the 400 mg/kg group. A few rats showed paralysis of hind leg in the 800 mg/kg group. The dosage of 1 600 mg/kg caused significant paralysis of hind legs, emaciation, and reduced weight gain. In the 1600 mg/kg group, the mating rate of male rats was significantly affected (P < 0.01). In the 800 and 1 600 mg/kg group, fertility of male rats was markedly reduced (P < 0.01). In the 800 mg/kg group, the effect on sperm counts of epididymis of male rats was markedly reduced (P < 0.05). In the 1 600 mg/kg group, testicle weight and body weight ratio and sperm counts of epididymis rate were significantly (P < 0.001) reduced. In the 1 600 mg/kg group, the fertility rate of female rats was remarkably (P < 0.001) reduced. In the 800 mg/kg group, the weight gain of pregnant rats was significantly reduced (P < 0.001). In both the 800 and 1 600 mg/kg groups, the gestation rate was greatly reduced (P < 0.001). In the 800 mg/kg group, mortality rate before nidation (P < 0.001) and average live fetus number were significantly reduced (P < 0.05). In the 400 mg/kg group, the fetal weight was significantly reduced (P < 0.001). In the 800 mg/kg group, body length, tail length, body weight and sternum development of fetal rats were significantly affected (P < 0.001).

CONCLUSIONUnder the presented experimental conditions, metadoxine has no teratogenic effects on SD rats and the no effect dose is 400 mg/kg. And the no effect dose for the developmental toxicity is less than 400 mg/kg.

OBJECTIVETo establish an effective method of genetic diagnosis on hemophilia A (HA) by detecting the inversion mutation in intron 22 of F8 gene.

METHODSIntron 22 inversion mutation in F8 gene was detected by using long distance-polymerase chain reaction (LD-PCR) and inversion-PCR (I-PCR) in 31 HA patients. The mothers of HA patients with intron 22 inversion mutation were selected to carrier diagnosis and amniotic fluid of the pregnant women with inversion mutation was collected at intermediate stage of gestation, and used to prenatal genetic diagnosis.

RESULTSSeven patients showed F8 gene inversion mutation in thirty-one patients. Three in four mothers of HA patients with intron 22 inversion mutation were diagnosed as carriers. The prenatal diagnosis result indicated that the fetus conceived in the HA-carrier woman was normal individual.

CONCLUSIONThe detection of intron 22 inversion mutation by LD-PCR and I-PCR is time-saving, and can be used in prenatal diagnosis on HA.

In this study, the current status for breast diseases in a region with high-incidence of cervical cancer were epidemiologically investigated. From March to August, 2009, 17618 women, from Wufeng area of Hubei province, China, were recruited to screen breast diseases by using breast infrared diagnostic apparatus. Other diagnostic methods, such as B-mode ultrasound, X-ray mammography, needle biopsy and pathological examination were, if necessary, used to further confirm the diagnosis. The screening showed that 5990 of 17618 cases (34.00%) had breast diseases, 5843 (33.16%) had mammary gland hyperplasia, 48 (0.27%) had breast fibroadenoma, 11 (0.06%) had breast carcinoma, and 88 (0.50%) had other breast diseases. The peak morbidity of breast cancer was found in the women aged 50-60 ages. The morbidity of breast cancer was significantly increased in women elder than or equal to 50 years old (n=8, 0.157%) in comparison with that in the subjects younger than 50 years old (n=3, 0.024%) (u=2.327, P<0.05). It was shown that the occurrence of breast diseases was concentrated in women aged 20-40 years, while the total morbidity reached its peak at the age of 30 years and then decreased sharply after age of 40. Compared with the patients elder than or equal to 40 years old (n=3289, 27.46%), the morbidity rate of breast diseases was significantly increased in women less than 40 years old (2648 cases, 47.18%; P<0.001). However, there was no significant difference in the morbidity of breast diseases between the age group of 20-29 years and that of 30-39 years (P=0.453), and both of them were high. There was no significant association between the morbidity of breast diseases and cervical cancer. Since the morbidity of breast diseases was higher among young women, more attention should be paid to the screening of breast diseases among young women for early diagnosis.

OBJECTIVETo investigate the alteration of HBV markers in liver allograft of HBV related recipients pre and post liver transplantation under Lamivudine or combination of Lamivudine with HBIG prophylaxis and explore the mechanism of HBV de nova infection in liver allograft after orthotopic liver transplantation, as well as seek to establish a optimal prophylactic protocol.

METHODSThe serial liver biopsy specimens of 90 liver allograft and sera of 78 liver transplant recipients during operation and after 1 week, 1 month, 3 months, 6 months, 12 months, 24 months post transplantation have been collected and detected for HBV markers with enzyme-linked radioimmunoassay, fluorescent quantitative assay for HBV-DNA in serology and with immunohistochemistry stain, HBV-DNA in situ hybridization in histology for detection of HBV markers in liver allograft samples.

RESULTSWhether recipients with active replicative or inactive replicative HBV preoperatively, none of positive HBV-DNA, HBsAg and HBcAg in 100% liver biopsy specimens with HBV-DNA hybridization in situ and immunohistochemistry stains in histology within 2 hours after reperfusion.

CONCLUSIONWhatever HBV replicative status the recipients have before surgery, no evidence of HBV particles direct invasion to the liver allograft from HBV related cirrhotics during operation under current prophylactic measures. However, the further supposed mechanism and its significance in HBV de nova infection of liver allograft remained to be disclosed further.
