OBJECTIVE: To explore the relationship between the portal hemodynamics or the indices of liver fibrosis and the liver function score in patients with different traditional Chinese medical syndromes of liver cirrhosis. METHODS: One hundred and forty-seven cases of liver cirrhosis with different syndromes were included in the study. Diameters and blood flow velocities of the portal vein and splenic vein were tested by color Doppler sonarography. The indices of liver function (TBIL, ALT, AST, Alb, Glb, PTA) and the indices of hepatic fibrosis (HA, PC-III, LN, VI-C) were tested. RESULTS: The diameters of portal vein in liver cirrhosis patients with different syndromes (internal accumulation of of damp-heat, stagnation of liver-qi, superabundance of dampness due to spleen-asthenia, asthenia of liver and kidney yin, asthenia of spleen and kidney yang, blood stasis) were not significantly different. The blood flow velocities and flow volumes of portal vein in patients with the blood stasis syndrome and the internal accumulation of damp-heat syndrome were significantly different (P < 0.05). The diameter of splenic vein in patients with the internal accumulation of damp-heat syndrome was significantly different to that of the asthenia of liver and kidney yin syndrome, or the blood stasis syndrome, or the asthenia of spleen and kidney yang syndrome, respectively (P < 0.05 or P < 0.01). The blood flow velocity of splenic vein in patients with the blood stasis syndrome or the asthenia of spleen and kidney yang syndrome was significantly different to that of the internal accumulation of damp-heat syndrome, or the stagnation of liver-qi syndrome, or the asthenia of liver and kidney yin syndrome, respectively (P < 0.01). The blood flow volume of splenic vein in patients with the internal accumulation of damp-heat syndrome was significantly different to that of the asthenia of liver and kidney yin syndrome, or the asthenia of spleen and kidney yang syndrome, or the blood stasis syndrome, respectively (P < 0.01). The liver cirrhosis indices HA and PC-III in patients with the asthenia of liver and kidney yin syndrome were significantly different to those of the internal accumulation of damp-heat syndrome (P < 0.05). In Child-Pugh classification, the incidence of Child-Pugh C was the highest in the asthenia of spleen and kidney yang syndrome, while the incidence of Child-Pugh A was the highest in the stagnation of liver qi syndrome. CONCLUSION: The changes of portal vein dynamics in liver cirrhosis patients with the asthenia of liver and kidney yin syndrome, or the asthenia of spleen and kidney yang syndrome, or the blood stasis syndrome are significantly different to those of the internal accumulation of damp-heat syndrome and the stagnation of liver-qi syndrome.

ObjectiveTo investigate the expression and relationship of pituitary tumor transforming gene (PTTG) and p53 protein in large intestinal adenoma,large intestinal carcinoma and normal large intestinal mucosa tissues.MethodsImmunohistochemistry was employed to determine the expression of PTTG and p53 protein in 50 cases with large intestinal adenoma tissues,42 cases with large intestinal carcinoma tissues and normal large intestinal mucosa tissues.The relationship of the expression of PTTG and p53 protein with the clinicopathological characteristics was analyzed.ResultsThere was no positive expression of p53 protein in normal large intestinal mucosa tissues,while the positive rate of PTTG expression was 7.14％(3/42).The positive rates of PTTG and p53 protein expression were 82.00％(41/50) and 90.00％(45/50) in large intestinal adenoma tissues,88.10％ (37/42) and 95.24％ (40/42) in large intestinal carcinoma tissues.The positive rates of PTTG and p53 protein over expression were 45.24％(19/42) and 69.05％(29/42) in large intestinal carcinoma tissues.The positive rates of PTTG and p53 protein expression in large intestinal carcinoma tissues were higher than those in large intestinal adenoma tissues and normal large intestinal mucosa tissues,the positive rates of PTTG and p53 protein expression in large intestinal adenoma tissues were higher than those in normal large intestinal mucosa tissues,and there were significant differences(P ＜ 0.05).The expression of PTTG was not correlated with p53 protein in large intestinal carcinoma tissues(P＞ 0.05 ),while the positive relationship was found between the expression of PTTG and p53 protein in large intestinal adenoma tissues (P ＜ 0.05 ).The over expression of PTTG was significantly correlated with lymph node metastasis (P ＜ 0.01 ),but the over expression of p53 protein was not correlated with lymph node metastasis(P ＞ 0.05) in large intestinal carcinoma tissues.Conclusions The expression of PTTG is significantly correlated with p53 protein in large intestinal adenoma tissues,and their co-expression may be used as markers for carcinogenesis of large intestinal adenoma tissues.The over expression of PTTG and p53protein is found in large intestinal carcinoma,and the over expression of PTTG is correlated with lymph node metastasis.The over expression of PTTG may be used as a marker for lymph node metastasis of large intestinal carcinoma.

Simple and effective methods are needed for the identification of Chinese medicinal material species and their variety. Lonicera japonica Thunb. is one of Chinese herbal medicines widely demanded. A total of 3 705 EST-SSRs of L. japonica and 2 818 EST-SSRs of L. japonica var. chinensis Thunb. were identified from EST database in our lab. In average, there was one EST-SSR per 4.05 kb in L. japonica ESTs and per 7.49 kb in L. japonica var. chinensis ESTs, separately. The identified SSRs in L. japonica were consisted of 51.98% dinucleotide and 34.61% trinucleotide repeats, while SSRs in L. japonica var. chinensis had 57.45% dinucleotide and 30.09% trinucleotide. The results reviewed that the classes AG/TC and GAG/TCT were predominant in the dinucleotide motifs and the trinucleotide motifs, respectively. Total 87 EST-SSRs were identified of significant difference between L. japonica and L. japonica var. chinensis. PCR products were obtained from 52 L. japonica samples in 13 out of 15 SSR markers tested. The polymorphism in L. japonica, L. japonica var. chinensis and other honeysuckles could be distinguished by three markers (jp.ssr4, jp.ssr64 and jp.ssr65) tested.

Objective To investigate the epidemiological characteristics of gonorrhea,and to analyze its temporal-spatial clustering in Zhejiang province.Methods Data on the incidence and demographic characteristics of gonorrhea in Zhejiang province from January 2004 to December 2012 were obtained from the China Information System for Disease Control and Prevention.The population,time and space distributions of gonorrhea were described.Epidemic curve and incidence maps were drawn.A space-time permutation scan statistic was used to detect space-time clusters,and spatial autocorrelation analysis was performed to calculate the Moran's I value and draw Local Indicators of Spatial Association (LISA) cluster maps.Results In Zhejiang province,a total of 199 956 cases of gonorrhea were reported with a decreasing trend in incidence rate from 2004 to 2012.The male to female ratio was 3.51:1 (155 634/44 331).People aged between 25 and 60 years accounted for 75.21％ of these patients,whereas the constituent ratio of people aged 0-1 years and ＞ 60 years increased with time.The incidence rate of gonorrhea was significantly higher in middle and north parts than in the south part of Zhejiang province,and higher in summer than in winter and spring with the peak incidence observed in August.Thirteen temporal-spatial clusters were detected,with the large clusters in Hangzhou,Huzhou,Ningbo,Shaoxing and their neighbor counties/cities/ districts,as well as some counties/cities/districts in Jinhua.All of the above clusters lasted 4.5 years.LISA maps showed an increasing trend in high-high aggregation counties/cities/districts which spread from the north to south part of Zhejiang province.Conclusion There is a temporal-spatial aggregation of gonorrhea in Zhejiang province with young and middle-aged men as the main affected population.
