Hyperlipidemia is one of the main basic lesions of blood vessels and organ diseases. Traditional Chinese medicine (TCM) has been used in the prevention and treatment of hyperlipidemia with advantages such as little drug side effects and obvious efficacy. The establishment of hyperlipidemia diagnostic aid platform helped to improve treatment efficiency, and provide a platform for data acquisition, storage and analysis for research on hyperlipidemia syndrome standardization. At first, a collection system was implemented, which was consisted of tongue image and the text information of the other three diagnostic methods, for doctor's accurate mastering of patient's clinical manifesta-tions and improvement of therapeutic effect. Through this platform, a clustering algorithm was applied to analyze clin-ical information of four diagnostic methods among 897 hyperlipemia cases, which had been classified into 5 cate-gories. Compare disease characteristics of samples in every category with syndromes category and find out the rela-tionships between them, by which the foundation of hyperlipemia syndrome differentiation standardization will be es-tablish. It provided suggestions on TCM syndrome differentiation and diagnosis.

This study was aimed to establish fingerprints of Citri Sarcodactylis Fructus from different geographical origins,and to use the method of pattern recognition to compare the differences of Citri Sarcodactylis Fructus from different habitats.In this study,high performance liquid chromatography (HPLC) was used to establish fingerprints for 25 batches of Citri Sarcodactylis Fructus from 4 habitats.Furthermore,similarity evaluation,cluster analysis (CA) and principal component analysis (PCA) were performed.The results from established fingerprints showed that a total of 26 common peaks were pointed out and 4 peaks were identified as the common peaks.The CA and PCA can be used to compare Citri Sarcodactylis Fructus from different habitats.It was concluded that Cirri Sarcodactylis Fructus in near geographic origins had a higher similarity,while the different geographic origins had a higher difference.

AIM: To observe the effect of continuous inhaled nitric oxide (NO) on airway resistance in guinea pigs. METHODS: 36 healthy male guinea pigs were divided into control group, isoproterenol group and two inhaled NO (20?10 -6 and 60?10 -6 ) groups. Respiratory resistance (R_E) and dynamic compliance(C_ dyn )were recorded before and after evoked by histamine at different doses. RESULTS: After injections of intravenous histamine at 80,120 and 160 ?g/kg, the R_E of inhaled NO groups were apparently lower than that of control group. Compared with control group, the C_ dyn of inhaled NO groups were significantly higher after administration of histamine at 80, 120 and 160 ?g/kg. After given histamine at more than 80 ?g/kg,the R_E of inhaled NO groups were higher and the C_ dyn lower than those of isoproterenol group. CONCLUSION: Inhalation of 20?10 -6 NO and 60?10 -6 NO can inhibit the increase in airway resistance induced by higher doses (80,120 and 160 ?g/kg )of intravenous histamine, but the effect of intravenous isoproterenol seems stronger.

Objective To study the role of transcranial Doppler (TCD) in early diagnosis of posttraumatic vasospasm in traumatic brain injury patients and in treatment effect monitoring of hyperxia liquid for this condition. Methods Seventy-four patients with posttraumatic vasospasm were divided into two groups. The control group (n=42) received the general treatment, while the treatment group (n=32) received the treatment of hyperxia liquid in addition to the general treatment. Their cerebral blood flow velocities of bilateral MCA and extra-cranial portion of ICA were monitored regularly by TCD, starting from the first day after head injury until 14th day. The changes of physiological and neurofunctional parameters in both groups were compared, including cerebral vasospasm(CVS),arterial blood oxygen pressure (PaO 2),arterial blood oxygen saturation (SaO 2), the Glasgow coma scale (GCS)and the ultimate effects of treatment as indicated by Glasgow outcome scale(GOS). Results Cerebral vasospasm occurred in 1 to 3 days and peaked to the 3 to 7 days after injury, then markedly relieved at 14 days after injury. After infusion of hyperxia liquid, the PaO 2 and SaO 2 in the treatment group were significantly higher than those of the control group. The degree of vasospasm was significantly higher in the control group than that in the treatment group. GCS and GOS of the treatment group were significantly higher than those of the control group. Poor outcome was common in patients with severe cerebral vasospasm. Conclusion Early posttraumatic vasospasm can be detected by TCD. High-oxygen liquid is effective for treating posttraumatic vasospasm.

Objective To study the correlation between nontraumatic osteonecrosis of femoral head (NONFH) and ApoA1 polymorphism of blood stasis type.Methods Totally 93 cases of NONFH were selected as the case group, and 83 healthy volunteers were randomly selected as the control group. With TCM constitution questionnaire survey, the case group was screened out 32 cases of blood stasis NONFH type and 61 cases of non blood stasis NONFH type. In the case group and control group, the subjects took blood samples 2 mL, extracted DNA for PCR amplification, PCR products for DNA sequencing. G994T PAF-AH and rs9658282 gene NOS1 site polymorphism were detected for tatistical analysis.Results -75G/A gene AA ApoA1 genotype (OR: 2.578; 95%CI: 1.174-5.663;P=0.018) and A allele (OR: 1.726; 95%CI: 1.121-2.658;P=0.013) may be one of the risk factors of NONFH.Conclusion -75G/A gene ApoA1 may be related to the pathogenesis of NONFH. There was no correlation between the ApoA1 gene polymorphism of -75G/A gene and the pathogenesis of blood stasis NONFH. There was no correlation between the ApoA1 gene polymorphism of +83C/T gene and the pathogenesis of blood stasis NONFH.

Objective To discuss the relationship between TCM constitutional types and the levels of transforming growth factor beta 1 (TGF-β1) of patients with knee osteoarthritis (KOA). Methods A total of 161 patients with KOA as a case group filled out questionnaires about 9 TCM constitution types, and 50 cases of unrelated healthy volunteers were selected randomly as control group. The serum samples of two groups were collected. The levels of TGF-β1 were detected and compared by double antibody sandwich ELISA. Results Compared with the control group, the level of TGF-β1 in the case group decreased, with statistical significance (P<0.05). Compared with the control group, the levels of TGF-β1 significantly decreased in the case group of qi deficiency type, with statistical significance (P<0.05). There were no types of special intrinsic and blood stasis. Compared with the control group, the levels of TGF-β1 in the other six types of patients with KOA had no statistical significance (P>0.05). Conclusion The incidence of KOA with qi deficiency type may be related to the decrease of TGF-β1 level. The decreasing level of TGF-β1 may be one of the mechanisms of molecular biology that qi deficiency was linked to KOA.

Objective To study the relation between alcohol-induced osteonecrosis of femoral head (AIONFH) related with high morbidity TCM constitution type with CYP2C8 gene polymorphisms.Methods Totally 152 Han nationality NONFH cases from Feburary 2014 to September 2015 from outpatient and the inpatient departments in Gansu Province Hospital of TCM were collected. 50 AIONFH cases were set as medical case group; meanwhile, 45 healthy volunteers were enrolled as control group. Database for medical materials of all patients and volunteers was established. TCM distribution for AIONFH patients was determined. Solution DNA extraction kit was used to extract DNA, and detect the concentration and purity of DNA. The target gene was amplified by PCR and the target gene was amplified by gel electrophoresis. The length of the fragment was confirmed to conduct target gene sequencing. With the results of sequencing and gel electrophoresis, the relation of AIONFH with CYP2C8 gene polymorphism in AIONFH patients with phlegm-dampness syndrome and the control group.ResultsThe CYP2C8 gene loci rs17110453 gene polymorphism was not statistically significant between the two groups (χ2=0.253,P>0.05). There was no significant difference in allele between the two groups (χ2=0.077,P>0.05). The risk of disease in CC genotype was 1.37 times higher than the AA genotype (95%CI: 0.339-5.540), without statistical significance (P>0.05). There was no significant difference in genotype and allele distribution between AIONFH patients with phlegm-dampness and non-phlegm-dampness and the control group (P>0.05).Conclusion CYP2C8 gene loci rs17110453 gene polymorphism A/C mutation has no obvious relation with AIONFH risk. There is no clear relationship between CYP2C8 gene loci rs17110453 gene polymorphism with AIONFH.

Objective To probe the value of ultrasound in detection of malignant foci among multiple thyroid nodules. Methods Ultrasonograms of 83 patients with pathologically confirmed thyroid cancer combined with benign nodules were analyzed.Results Among 83 patients of thyroid carcinoma, 89 malignant and 87 benign nodules were detected with ultrasound. Significant differences of two-dimensional ultrasounic signs including low echoes, border fuzzy, micro-calcification and rear echo attenuation were found bteween malignant and benign nodules (P<0.01). There were significant differences in the grade Ⅱ, Ⅲ blood flow between malignant and benign ones (P<0.01). Of 89 malignant nodules, small thyroid carcinoma with diameter ≤1 cm accounted for 52.81% (47/89), and ultrasound diagnostic rate of all cancer nodules was 67.42% (60/89).Conclusion Ultrasounic characteristics including low echoes, border fuzzy, micro-calcification, rear echo attenuation and internal rich blood flow contribute to differentiate the thyroid microcarcinoma from multinodules.In particular, the microcarcinoma should not be ignored.

OBJECTIVETo detect genetic diversity of 48 population of Polygonum capitatum in Guizhou province.

METHODThe genetic diversity of 48 representational populations of P. capitatum including 240 individuals had been investigated by ISSR marker technique.

RESULTThe genetic diversity had been revealed as follow: A total of 8 293 bands were produced in 240 individuals, of which 7 962 bands were common in the 48 population. The value of the average percentage of polymorphic bands (PPB) was 79.09%, Nei's genetic diversity index (H(e)) was 0.245 8, Shannon's information index (I) was 0.396 2, and genetic differentiation index (G(st)) was 0.238 0 at population level, respectively. The genetic differentiation index (G(st)) was 0.072 2, genetic differentiation coefficient by Shannon's diversity (I(st)) was 0.044 2 within the population levels. Groups cluster analysis based on the UPGMA method indicated that although the 48 populations could be divided into 3 groups and the P. capitatum seed sources. The groups cluster showed that a cross clustering of P. capitatum between the southwest and southeast populations in Guizhou province, and no significant correlation was found between geographical and genetic distance among them.

CONCLUSIONThe genetic diversity of P. capitatum is relatively high at the population levels, while low within the population levels, a significant degree of genetic differentiation occurs among the populations. The groups cluster analysis indicated they has not apparent genetic variation in regional pattern between the place of origin populations and the migrate populations.
