Objective To explore the relationship between the expression of matrix metalloproteinase (MMP) and tissue inhibitor of metalloproteinase (TIMP) in gestational trophoblastie diseases and its invasiveness.Methods The expression and distribution of MMP-7,MMP-9,TIMP-1 and TIMP-2 were determined by immunohistochemistry PV-6000 in 49 cases of hydatidiform mole (eight of them with malignant transformation),six cases of invasive hydatidiform mole,two cases of choriocarcinoma and 18 cases with normal villi in early pregnancy.Results The expression of MMP-7,MMP-9,TIMP-2 and MMP- 9/TIMP-1 was significantly higher in choriocareinoma,invasive mole and malignant transformed mole than that in normal villi in early pregnancy and non-malignant transformed mole (F=10.950,7.760,7.304, 3.442;P

Hypertension is one of main risk factors for the occurrence and death of stroke and coronary heart disease. Its prevalence rate is rising year by year. It severely threatens the health of the human beings. The acupuncture method of "activating blood and dispersing wind, harmonizing Gan-Pi" for treating hypertension launched by Academician SHI Xue-min has aroused great attention due to good cur- ative effect and less adverse reactions. In this paper principles of the circular motion covered by the acupuncture method of "activating blood and dispersing wind, harmonizing Gan-Pi" were clarified.

4-coumarate coenzyme A ligase is a key enzyme of phenylpropanoid metabolic pathway in higher plant and may regulate the biosynthesis of ferulic acid in Angelica sinensis. In this study, the homology-based cloning and rapid amplification of cDNA ends (RACE) technique were used to clone a full length cDNA encoding 4-coumarate coenzyme A ligase gene (4CL), and then qRT-PCR was taken for analyzing 4CL gene expression levels in the root, stem and root tissue at different growth stages of seedlings of A. sinensis. The results showed that a full-length 4CL cDNA (1,815 bp) was obtained (GenBank accession number: KT880508) which shares an open reading frame (ORF) of 1 632 bp, encodes 544 amino acid polypeptides. We found 4CL gene was expressed in all tissues including leaf, stem and root of seedlings of A. sinensis. The expressions in the leave and stem were increased significantly with the growth of seedlings of A. sinensis (P < 0.05), while it in the root showed little change. It indicates a time-space pattern of 4CL gene expression in seedlings of A. sinensis. These findings will be useful for establishing an experiment basis for studying the structure and function of 4CL gene and elucidating mechanism of ferulic acid biosynthesis and space-time regulation in A. sinensis.

Objective To reveal and forecast the incidence trend of Brucellosis, in order to provide acientific basis for future intervention and policy-making. Methods Descriptive epidemiological method was used to analyze and statistically describe the distribution of the disease in different times, different locations and different (7.0783/10 million to 13.1257/10 million) and Qingxu ( 1.4811/10 million to 8.5241/10 million) were higher,followed by Yangqu county(0 to 5.8232/10 million), Xiaodian(0.8108/l0 million to 2.4229/10 million) and Jinyuan district ( 0.5329/ 10 million to 1.5896/10 million), and the remaining counties(districts) in the annual There were 223 cases of Brucellosis patients from 2006 to 2009 in Taiyuan. Vocational high risk population was farmers, with a total of 140 cases, accounting for 62.78% of the total number of incidence, followed by students and workers, respectively, 13, 14 cases, accounting for 5.83% and 6.28%, other occupational groups, 56 cases,77.58%;28 cases aged above 60 years, accounting for 12.56%;22 cases aged younger than 19 years, accounting identical in the four years, most cases occurred in spring and summer and showing a clear seasonal high.Conclusions The incidence trend of Brucellosis is on the rise from 2006 to 2009. High risk population is farmer,and the number of younger patients is on the rise, we propose strengthen protection for high risk groups.

Objective To report the outcome of emergency repair of severe complex defect in forearm by transplantation of free flap and simultaneous functional reconstruction.Methods From Mar.1994 to Aug.2003,4 cases with severe complex defect in forearm was repaired by transplantation of free skin flap, free skin flap combined with fibula flap,or fibula osteocutaneous flap in emergency.Simultaneously the flexion and extension function were repaired by muscle transfer and/or tendon grafting,tenonectomy.Results All the cases were successful.Follow-up period ranged from 1 to 3 years postoperatively.The blood-supply,tex- ture and elasticity of transferred flaps were excellent with good bone healing.Opposition of thumb with four fin- gers was good.Sensory recovery of the hand was satisfactory.Conclusion Transplantation of free flap com- bined with simultaneous functional reconstruction is an ideal method in emergency repair of severe complex de- fect in forearm.

UNLABELLEDOBJECTIVE To observe the changing laws of the protein expression of N-methyl D-aspartate receptor (NMDAR) in rat hippocampal subfields following focal ischemia/reperfusion injury, and to study the effects of sodium tanshinone B (STB) on it, thus exploring the possible mechanism of STB for treating cerebral ischemia.

METHODSThe rat model of focal cerebral ischemia/reperfusion injury was established using middle cerebral artery occlusion (MCAO) by reversibly inserting a nylon thread. The Wistar rats were randomly divided into the sham-operation group, the I/R model group, and the low, middle, and high dose STB groups. The neural functional disturbance was scored referring to the 5-grade Zea Longa EL standard. The protein expression of NMDAR1 in the ischemic side was detected using immunohistochemical assay.

RESULTSThere was statistical difference in the scores of the neural functional disturbance in the middle and high dose STB groups when compared with the model group (P < 0.01). Results of the immunohistochemical assay showed the expression of NMDAR1 in CA1 region was obviously higher in the I/R model group, the low and middle dose STB groups than in the sham-operation group (P < 0.01). The expression of NMDAR1 in CA1 region was obviously lower in the high dose STB group than in the I/R model group (P < 0.01), the low (P < 0.01) and middle dose STB groups (P < 0.05). The expression of NMDAR1 in CA3 region was obviously higher in the low dose STB group and the I/R model group than in the sham-operation group, the middle and high dose STB groups (P < 0.01). The expression of NMDAR1 in CA3 region was obviously higher in the high and middle dose STB groups than in the sham-operation group (P < 0.05).

CONCLUSIONSSTB could promote the recovery of neural functions in cerebral ischemia/reperfusion injury rats. STB fought against cerebral ischemia/reperfusion injury by lowering excitable neurotransmitter glumatic acid and reducing the protein expression of NMDAR1.

In this paper the contents of rosmarinic acid, salvianolic acid B, crytotanshinone, tanshinone II(A) in samples of different original processed Salvia Miltiorrhizae Radix et Rhizoma were determined by HPLC. Different processing methods have varied influences on four active ingredients in Salvia Miltiorrhizae Radix et Rhizoma. Sun-drying reduced the content of crytotanshinone, tanshi-none II(A) and rosmarinic acid, integralsamples were better than those cut into segments. Oven dry method had great influence on water--soluble ingredients, high temperature (80-100 degrees C) could easily cause big loss of rosmarinic acid and salvianolic acid B. The role of traditional processing method "fahan: was complicated, the content of rosmarinic acid decreased, crytotanshinone and tanshinone II(A) increased, and salvianolic acid B showed no difference after "fahan". Drying in the shade and oven dry under low temperatrure (40-60 degrees C) were all effective to keep active ingredients of Salvia Miltiorrhizae Radix et Rhizoma, and, there was no difference between integral samples and samples cut into segments. Therefore, considering comprehensively the content of active ingredients in Salvia Miltiorrhizae Radix et Rhizoma, and processing costing etc., shade-drying or oven dry underlow temperature (40-60 degrees C) should be the most suitable original processing method.
