Dried roots and rhizomes of Salvia miltiorrhiza (Danshen) are among the most commonly used traditional Chinese medicines in clinic. The material basis for its efficacy mainly includes hydrophobic tanshinones and hydrophilic salvianolic acids. The traditional effects of Danshen are "removing stasis and relieving pain, activating blood to promote menstruation, clearing heart fire and tranquilization". According to modern pharmacological studies, Danshen and its main components have cardiovascular and cerebrovascular protective effect. Recent studies showed that Danshen and its main components also demonstrated protective effects on liver injury models induced by carbon tetrachloride, D-galactosamine, acetaminophen and alcohol. In this paper, the hepatoprotective effect and mechanism of Danshen were summarized and studied.

Objective To retrospectively investigate the causes , location and the duration of hospital stays of the hospitalized patients with hard-to-heal wounds so as to provide data guidance for the prevention and research of these diseases. Methods Clinical data of hospitalized patients with hard-to-heal wounds in plastic surgery center of General Hospital of Guangzhou Military Command were collected from June , 2011 to December, 2013. Whether ulceration was recovered in the patients with skin tissue defect after 2 months treatment was regarded as the standard to screen the patients with hard-to-heal wounds. The causes , location, age and the duration of hospital stays of the hospitalized patients with hard-to-heal wounds were investigated by retrospective case-control method. Chi-square test and t-test were used in analyzing the investigation. Results 2 136 cases, aged from 20 to 86, were treated in plastic surgery center of the hospital. 120 cases have hard-to-heal wounds, which constituted 5.62% of all hospitalized patients. (1) Metabolic disease was the main causes of wound (43.3%), followed by wound infection and tumor (20.0% for each) (χ2 = 62.917, P < 0.01). ( 2 ) The peak age for patients with hard-to-heal wounds was 40 to 60 years old patients , followed by patients′age from 60 to 80 years. (3) The mostly like hard-to-heal wounds was on limbs (61.6%), especially on the foot (38.3%) (χ2 = 17.546, P = 0.002). (4) The average days for hospitalization of in the plastic surgery center were (7.41 ± 8.98), while the average days for hospitalization of the patients with years were (33.21 ± 28.27)(t = -9.968, P < 0.05). Conclusion The average diagnostic age of patients with hard-to-heal wounds is the middle and old aged patients. Chronic skin ulcers, which often occurs in a limb, seriously affects a person′s ability to move , which can prolong hospital stays , causing serious burden for the families of patients and the society.

The long-term administration of NaF on rats does not increase the bone formation of rats in growth period. The osteoblast activities as well as the bone absorption of lumbar vertebra were strengthened. The likelihood of bone fracture became larger. The negative effects on bone metabolism and bone quality of rats were gradually displayed along with the prolongation of sodium fluoride usage.

OBJECTIVETo observe the effect of combined therapy of Neiyi pill (NP) and Neiyi enema (NE) on endometriosis and its effect on serum levels of endometrial antibody (EMAB) and carcinoembryonic antigen 125 (CA125).

METHODSFifty-eight cases with endometriosis were divided into 3 groups randomly, group A (n = 16) treated by NP, group B (n = 24) treated by NP and NE, and group C (n = 18) treated by danazol, all for 3 menstrual cycle with single blind method. The effect was observed and the serum levels of EMAB and CA125 were detected before and after treatment.

RESULTSComparison of the efficacy between the 3 groups showed: there was no remarkable difference between group A and B (P >0.05), both of group A and group B were superior to that of group C (P<0.05). The levels of EMAB and CA125 had no significant changes in all the three groups after treatment.

CONCLUSIONCombined therapy of NP and NE could improve the curative effect on endometriosis, and without obvious effects on serum levels of EMAB and CA125.

Objective: To test the feasibility of drag-reducing polymers (DRP) for improving coronary microcirculation in a canine model in order to provide the experimental basis for treating myocardial microcirculation dysfunction. Methods: A total of 8 dogs received open-chest surgery and they had intravenous injections, in turn, with adenosine (ADN), DRP 250 mg/L and DRP+ADN. The function y=A × (1-e-βt) was used to calculate the myocardium capillary volume (A value), capillary velocity (β value) and myocardial blood lfow (A ? β value) by myocardial contrast echocardiography. Results: With DRP infusion, the A value in experimental canine was similar to the baseline condition,P>0.05; while theβ value and A ? β value were signiifcantly increased as (0.57 ± 0.10) 1/s vs (0.23 ± 0.03) 1/s,P<0.01 and (11.51 ± 1.96) VI/s vs (5.15 ± 0.86) VI/s,P <0.05 respectively. With combined infusion of DRP+ADN, the β value and A ? β value were similar to the baseline condition, bothP>0.05. Conclusion: DRP improved coronary microcirculation primarily by modulating the β value in experimental canine model, and hopefully, this unique hemodynamics could provide a new approach for treating myocardial microcirculation dysfunction.

Objective To investigate the pathologic morphology and immunohistochemical phenotypes of sarcomatoid carcinoma(SC) of the fallopian tube.Methods One case of SC of the fallopian tube was studied under the light microscopy for morphology.Immunohistochemistry was used to detect the expression of CK,EMA,S-100,Desmin,SMA,Leu-7,CD68,actin,and Vimentin in SC tissues.Pathologic features and biological behaviors of SC were analyzed in combination with the review of literature.Results Microscopically carcinomatous and sarcomatous elements co-existed.Usually the sarcomatous element formed the bulk of the lesion.In the sarcomatous tissues,there was no distinguishable bone,cartilage,rhadomyosarcoma,etc. Immunohistochemically the strong expression of CK7,EMA and Vimentin,and the partial expression of S-100,SMA,Leu7,CD68 and actin were detected.Conclusion SC of the fallopian tube is lack of specific symptoms,and its preoperative diagnosis is difficult.B-ultrasonography,CT and MRI are helpful to the staging of SC.Final diagnosis of SC depends on pathological examination and immunohistochemistry.SC is rare,and undergoes blood metastasis in early stage.Prognosis of SC is worst.Early detection of SC is the key to improve the prognosis.
