Objective To analyze retrospectively the result of nonspecific mastitis diagnosed by mammography and color Doppler's ultrasonic, and to improve the diagnosis accuracy of nonspecific mastitis as well as the ability to identify with breast cancer.Methods 31 cases of nonspecific mastitiswere examined by mammography and color Doppler's ultrasonic.All cases were punctured by biopsy or surgery, and confirmed by pathology.Results The coincidence rates between mammography and color Doppler's ultrasonic with pathology were 64.5% and 67.7% respectively.The coincidence rate between the combined mammography and color Doppler's ultrasonic with pathology were 87.1%.There was no statistically significant difference between the two separate inspection methods (P>0.05).Conclusion Mammography and color Doppler's ultrasonic have their own advantages in the diagnosis of nonspecific mastitis, and are easy to be confused with breast cancer.Combining mammography with ultrasonography can improve the accuracy of unspecific mastitis diagnosis and the ability to identify breast cancer.

Objective To study the nerve protective mechanism of puerarin on ischemic brain injured and observe the expression change of TNF-α cytokines in ischemic brain area. Methods 90 healthy male SD(Spraque-Dawley)rats were used to built the animal model of brain medium sized artery focal cerebral ischemia reperfusion with the patching methods, and the rats were randomly divided into three groups: Sham operation group(n=30),operation group(n=30),operation with puerarin interfered group(n=30).There were five different observing time in every group(6h,12h,24h,48h,72h after operation).The operation with puerarin group rats were treated with puerarin solution, the sham operation and operation group rats were injected the same volume Sodium Chloride. To observe the expression of TNF-α cytokines in different time, immunohistochemistry staining in ischemic region was used. Results Compared with the sham operation group. the expression of TNF-α cytokine in cerebral isehemic reperfusion brain tissue in the operation and the operation with puerarin interfered groups was higher(P＜0.01).Compared with the operation group, the expression of TNF-αcytokine was significantly decreased in different time after cerebral ischemic-reperfusion in the operation with puerarin interfered group(P＜0.01 or P＜0.05).Conclusions The puerarin can restrain the expression of the TNF-α cytokine.

Background and Objective Hyperlipidemia is one of the most potent and best substantiated risk factors for coronary heart disease (CHD). Purified Salvia miltiorrhiza extract (PSME) had been shown to have hypolipidemic effect in animal experiments. This study aimed to evaluate its iipids modulating effects in hyperlipidemic patients. Methods In this single-blind, placebo controlled study, lipid profiles of 80 hyperlipidemic patients were checked at same conditions. They were divided into two equal groups randomly (each composing of 40 patients). They were given PSME tablet (800 mg) three times per day, or placebo tablet. All patients were put on NCEP type Ⅱ diet and six weeks later, lipid profiles were checked. Results In PSME group, total cholesterol decreased by 27.32 mg/dl (12.3% reduction), LDL-cholesterol decreased by 23.13 mg/dl (16.8% reduction) and HDL-cholesterol increased by 9.06 mg/dl (11.1%), all were statistically significant. Although triglyceride dropped by 12.12 mg/dl (5.1%) but this was not significant statistically (P=-0.34). There were no significant changes oflipids levels in the placebo group. Conclusions PSME has significant favorable effect on total cholesterol, LDL-cholesterol, and HDL-cholesterol and may be a potential agent for the treatment ofatherogenic dyslipidemia.

Objective To investigate the early diagnosis and rational treatment of popliteal artery injury so as to im-prove the lower limb salvage rate. Methods The clinical and follow-up data integrity of 25 patients with popliteal artery injury was systematically studied. In these patients , 19(76%)cases were blunt injury and 6(24%) cases were penetrating injury. The combined injury included open fracture in 10 cases(40%) ,the knee joint dislocation with closed fracture of lower limb in 13(52%),nerve injury in 5(20%) and venous injury in 3(12%),respective-ly. The cause of delayed diagnosis and relationship between prognosis and type of injury, complications, the dura-tion from injured to treatment time were analyzed. Results 20 cases were operated to repair the popliteal artery. Endovascular treatment in 5 cases, the blood supply completely recovered (64%) in 16 cases, improved in 3 cases (12%) , 6 cases (24%) amputed, respectively. Rate of amputation within 6~8 hours was significantly lower than that of the more than 8 hours from the injuried to treatment time ( P<0. 05 ) . Amputation rate in blunt injury and combined injury was significantly higher than that of sharp injury ( P<0. 05 ) . Conclusion The duration from inju-ry to surgery more than 8 h, combined with knee joint dislocation and wound around knee is a major cause of mor-bidity. Operation with arterial thrombectomy is the main treatment, while endovascular treatment is a complementa-ry treatment to save the lower limb.

The clinical efficacy of two dosages of mifepristone plus methotrexate (MTX) in the treatment of ectopic pregnancy was compared.One hundred and fifty patients with ectopic pregnancy patients were stratified randomly into 200 mg's single oral group (n =77) and 150 mg graded oral group (n =73).The results showed that,when the Fernandez scores ≤ 12 points,the difference of treatment success rate was not statistically significant (98％ vs 100％,P ＞0.05) ; and when ＞ 12 points,two groups had statistical significance difference (10/13,3/11,P ＜ 0.05).The incidence of gastrointestinal adverse reactions was statistically significant between two groups (P ＜ 0.05).However,the number of leucopenia,the time of hCG back to normal and average length of hospital stay were not statistically different(P ＞0.05).

Castor(Ricinus communis L.),a high energy-stored and industrial raw-material plant species,is of great value in its application.Progresses in castor biotechnology were summarized in terms of tissue culture and genetic transformation.The results of studies on tissue culture indicated that application of TDZ(thiadiazuron) gave the maximum rate of shoot proliferation in various exogenous hormones when embryo axis was used as explant.On this ground,the in vitro regeneration system was established.The studies on castor genetic transformation showed that the Agrobaterium-mediated method was the most suitable one in different castor transformation methods.The hygromycin is suitable to selection of castor transfomants while castor embryo axis is insensitive to kanamycin.The possibilities of breeding of new castor varieties and improvement of castor production via biotechnology were also discussed.

Objective:To compare the antihypertensive effects of tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) to screen the best tuina protocol for primary hypertension due to liver-fire flaming-up.Methods:A total of 102 patients with primary hypertension due to liver-fire flaming-up were randomly divided into a Taichong (LR 3) group,a Neiguan (PC 6) group and a Qiaogong (Extra) group according to the random number table,with 34 cases in each group.Patients in the three groups received 4-week tuina treatment with the corresponding acupoint respectively.The blood pressure was recorded by benchtop mercury sphygmomanometer before tuina,immediately after tuina treatment,30 min and 60 min after tuina treatment with the patient in a supine position in a quiet treatment room.The total effective rate was observed.Results:The systolic and diastolic blood pressures of the three groups all decreased after treatment (all P＜0.05).The decrease of systolic and diastolic blood pressure at different time points after treatment in the Qiaogong (Extra) group and the Taichong (LR 3) group were better than those in the Neiguan (PC 6) group (all P＜0.05).Qiaogong (Extra) group had the highest total effective rate though there was no statistical difference in the total effective rate among the three groups (P＞0.05).Conclusion:Treating primary hypertension due to liver-fire flaming-up with tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) can reduce systolic and diastolic blood pressure respectively,among which Qiaogong (Extra) has the highest total effective rate.

Objective To compare the efficacy and side effects of intermittent androgen depriva-tion (IAD) versus continuous androgen deprivation (CAD) in prostate cancer. Methods Forty-four patients with prostate cancer were divided into 2 groups. Twenty-one cases (group IAD) received IAD therapy. Of them, TNM staging showed T2 in 7 cases, T3 in 9 cases, T4 in 5 cases. The patients were treated by maximum androgen blockage until the serum PSA decreased to less than 0.2 ng/ml and maintained for 2 months. The treatment was resumed when the serum PSA increased up to 10.0 ng/ml or the symptoms occurred progress. Twenty-three cases (group CAD) underwent CAD therapy. Of them, TNM staging showed T2 in 7 cases,T3 in 12 cases,T4 in 4 cases. The time to prostate cancer progression,quality of life and side effect rate were compared between the 2 groups. Results The median time to disease progression was (36±4) months in group IAD and (30±4) months in group CAD,respectively. There was no significant difference between the 2 groups (P=0.132). The mean cycle length was (15.9±2.3) months, among them time on treatment and time off treatment were(8.8±1.5) months and (7.3±0.8) months, respectively. The symptom scores related to treatment in the treatment period and intermission of IAD group were 55.9±16.8 and 47.9±19.7, respective-ly, there was significant difference between them(P=0.007). But the differences between the treat-ment period and intermission in bone pain,urinary and intestinal symptoms were not significant (P> 0.05). The urinary symptom scores after 5 months of continuing treatment in groug CAD was signifi-cantly higher than the basis reference value which was obtained in the sixth month of initial treatment(P=0. 023), but there was no significant changes in the scores of bone pain, intestinal symptoms and symptoms related to treatment(P>0.05). The incidences of hot flash and gynecomastia were 28.6% (6/21) and 19.0%(4/21) in group IAD, 60.9%(14/23) and 52.2%(12/23) in group CAD, respec-tively. There were significant differences between the 2 groups(P<0.05). Conclusions IAD thera-py can alleviate the side effects of androgen deprivation therapy and improve the life quality. The effica-cy of prolonging the time to androgen independence of IAD therapy is similar to CAD therapy.
