Chinese medicinal decoction pieces were the mainly form for traditional Chinese medicine (TCM) treatment,which means TCM prescription drugs.Any processed (heated or unheated) pieces are known as prepared pieces,which include both raw and cooked pieces.Based on differences of the clinical application of processed pieces,this paper summarized three traditional processing theories,such as the raw and prepared effect difference theory,processing accessories action theory,and pharmaceutical theory.The key points were focused on how different processing methods affect the properties of Chinese herbs,such as four natures and five flavors,floating and sinking,attributive channel,tonifying or purging action,and the toxicity.Based on changes of pharmacodynamic substance base and pharmacological action before and after processing,the action mechanism of processing in changes of Chinese medicinal properties was explained.

Objective To explore the effects of leukocyte in the injured foci on brain edema after brain contusion,in order to provide theoretical basis of clincial treatment of traumatic brain injury.Methods Traumatic brain injured animal model was established with injecton of blood components,forty five rats were randomly divided into three groups i.e,traumatic brain injure (TBI) group,whole blood(WB)group and white blood cell(WBC) group.Each group was further divided into three subgroups.All rats were killed at 24, 72 or 120 hours after injury,the water content, sodium, potassium and calcium contents were measured in brain tissue of areas injured.Results There was a peak of brain water and sodium contents in TBI, WB and WBC groups at 3 days after injury;Brain water content of TBI group was significantly lower than both WB group and WBC group (P

Objective To investigate the role of cyclophilin A (CypA) and CD147 in the process of skin aging. Methods Twenty cases of tissue samples from junior group(<15 years old), middle age group(30-40 years old)or old age group (>65 years old) were collected from photophobic and exposal parts of skin, respectively. Immunohistochemistry (IHC) and in situ hybridization (ISH) were carried out to semi-quantitatively detect the expression level of CyPA and CD147. Results IHC demonstrated that both CyPA and CD147 were expressed in both photophobic and exposal parts of normal human skin in all 3 groups. The expression levels of both CyPA and CD147 were increased with increase in age. There were significant differences in both CyPA and CD147 expression among 3 groups (P<0.05). CyPA and CD147 were also positively correlated in all 3 groups. Similar results were achieved by ISH. Conclusion The interaction between CD147 and CyPA might play an important role in the process of skin aging.

To study the interaction of drugs of different properties, namely puerarin, borneol and catalpol in the process of in- clusion, in order to explore the inclusion regularity of multi-component and multi-property traditional Chinese medicine compound in- clusions. With HP-β-CD as the inclusion material, the freeze-drying method was used to prepare the inclusion. The inclusion between puerarin, borneol and catalpol was tested by measuring the inclusion concentration, DSC and X-ray diffraction. According to the find- ings, when insoluble drugs puerarin and borneol were included simultaneously, and puerarin was overdosed, puerarin included was almost equal to puerarin included, and borneol was not included. When puerarin was under-dosed, and HP-β-CD was overdosed, borne- ol was included, and the simultaneous inclusion was lower than the separate inclusion of borneol. When water-soluble drug catalpol was jointly included with puerarin or borneol, the simultaneous inclusion was almost the same with their separate inclusion, without charac- teristic peak of catalpol in DSC and X-ray diffraction patterns. There is a competition in the simultaneous inclusion between water-solu- ble drugs puerarin and borneol and a stronger competition in puerarin. The water-soluble drug catalpol could be included with HP-β-CD with no impact on the inclusion of puerarin or borneol.

Objective To observe the time-dependent changes of astrocytes and microvessels in the ischemic core and surrounding areas.Methods Glial fibrillary acidic protein (GFAP)was measured by HE,and CD31 by immunohistochemistry as markers in post-mortem specimens from ten patients,who died of cerebral infarction.Results Each section of the infarcted brains was divided into four areas (the area 0-3).GFAP expressed a little in area 0 and 1,increased in a time-dependent manner in area 2 and 3;CD31 die not expressed in area 0,expressed a little in the area 1,and increased in area 2 and 3 continuously.Conclusions The proliferation of astrocytes and microvessels may play a significant role in the process of restoration after cerebral infarction.

Objective To investigate the related factors of clinical incidence and the ultrasound diagnostic value of endometrial polyps (EMP).Methods A total of 278 patients with clinical abnormal vaginal bleeding,menorrhagia,infertility,cervical polyps or physical examination showing EMP received vaginal ultrasound and hysteroscopy.The related clinical factors were recorded and single factors and multivariate unconditional Logistic regression analysis were carried.Results The univariate analysis showed that the number of pregnancy,menopause,placing intrauterine device,oral comtraceptives,history of hormone therapy,chronic endometritis,cervical polyp,merger endometriosis and obesity were the statistically significant factors of EMP incidence (P < 0.05 or < 0.01),which were used as dependent variables for multivariate Logistic regression analysis,indicating that menopause,chronic endometritis,history of hormone therapy and cervical polyp significantly affecting EMP incidence (P < 0.05),with OR values of 4.068,4.122,3.770 and 3.983 respectively.Conclusion Menopause,chronic endometritis,history of hormone therapy,cervical polyps are the related risk factors of EMP.

The susceptibility to 9 kinds of antibiotics of 393 animal pathogenic E. coli isolated from clinical samples was determined from 2000 to 2003. The resistance to TC, GM, CMP, AMP, RA, KM, FT, SM and CIP were 93.89%, 57.76%,78.63%, 77.86%, 92.11% ,47.33%, 46.82%, 76.84% and 74.81%, respectively. The isolates could be classified into eight classes according to the number of drugs to which srains were resistant. The resistance spectrum of the isolates varied from 2to 9 kinds of the above drugs. The strains that were resistant to seven kinds of drugs were more than 80 percent. The resistance rates of swine origin strains to GM,AMP and KM were higher than those of poultry origin strains, while the resistance rates of poultry origin strains to TC, CMP, SM and CIP were higher remarkably than those of swine origins. The frequency of resistance increased from 2000 to 2003,which was from 67.33% to 90.58% for CMP, 71.29% to 84.81% for AMP, 73.76%to 80.10% for SM and 61.88% to 88.48% for CIP. At the same time, the resistance rate of GM decreased from 61.39% to 53.92%. Thirty-seven strains (95 %) could make all the Kunming mice die within 72 h injected intraperitoneally with the culmice three times in vivo. The pathogenicity of wild strains with drug resistance acquired naturaly to mice did not decline.

With the rapid increase of the number of cardiovascular disease patients in China, and the popular trend of cardiovascular disease risk factors is becoming more and more obvious, the control of risk factors for cardiovascular disease has become an important public health problem as well as a great challenge to social and economic development. Recent studies show that resistance training plays a positive impact on the control of risk factors for cardiovascular disease. This article reviewed the related literature in recent years for the resistance training control risk factors of the cardiovascular disease, and stated the precautions and challenges during the process of the implementation of resistance training in order to provide new clues to the research and practice for control the risk factors of cardiovascular disease .
