s: The horse mushroom (Agaricus arvensis Schaeff ex Fr.) is one of most excellent edible mushroom,and was cultivated in world at resent year.But up to now,the breeding systems and life-cycle of horse mushroom has been poorly know.In this study,the random amplified polymorphic DNA was employed to analyse the mating reaction between self-fertile homokaryonic isolates by paired.The results demonstrated: (1) the mating reaction happened and the heterokaryonic offspring formed when the intercompatible self-fertile homokaryonic isolates were paired;(2) perhaps the horse mushroom is possessed of double breeding systems-homothallism and heterothallism;(3) RAPD is very effective method for verifying artificially synthesized heterokaryons and monitoring the transmission of genetic loci in mating of fungi.

OBJECTIVETo investigate the effect of tanshinone II(A) on the expression of different components in the renin-angiotensin system of left ventricles of renal hypertensive rats.

METHODThe renal hypertension model was established in rats by the two-kidney-one-clip (2K1C) method. In the experiment, all of the rats were randomly divided into four groups (n = 15 per group) before the operation: the sham-operated (Sham) group, the hypertensive model (Model) group, the low-dose tanshinone II(A) group and the high-dose tanshinone II(A) group. At 5 week after the renal artery narrowing, the third and fourth groups were administered with 35 mg kg(-1) x d(-1) and 70 mg x kg(-1) x d(-1) of tanshinone II(A), respectively. The blood pressure in rats was determined by the standard tail-cuff method in each week after the operation. After the drug treatment for 8 weeks, all the rats were put to death, and their left ventricles were separated to determine the ratio of left ventricle weight to body weight (LVW/BW), the myocardial collagen content, and the expressions of different components in myocardial RAS, including angiotensin converting enzyme (ACE), angiotensin converting enzyme 2 (ACE2), angiotensin 1-type receptor (AT1R), Mas receptor mRNA expression and angiotensin II (Ang II) and angiotensin (1-7) [Ang (1-7)] content.

RESULTCompared with the sham group, the hypertensive model group exhibited a markable increase in the content of Ang II and Ang (1-7) and the mRNA expressions of ACE, ACE2, AT1R and Mas (P < 0.01). However, the treatment with tanshinone II(A) showed the does dependence, inhibited left ventricle hypertrophy, decreased myocardial Ang II content and the mRNA expression of ACE and AT, R in renal hypertensive rats (P < 0. 01) , further increased the myocardial Ang (1-7) content and the mRNA expression of ACE2 and Mas (P < 0.01) , but without any change in the blood pressure of hypertensive rats.

CONCLUSIONThe treatment with tanshinone II(A) could inhibit left ventricle hypertrophy of renal hypertensive rats. Its mechanism may be partially related to the expression of different components in the renin-angiotensin system for regulating myocardial tissues.

Objective To discuss perioperative rehabilitative care for flexor tendon injuries by examples of successful treatment of 30 cases of rupture of flexor tendon pollicis longus at ZoneⅡ.Methods From March 2001 to March 2006,30 cases of rupture of flexor tendon pollicis longus at ZoneⅡwere treated in our department by suture with double loops and crossing six strands before external fixation.Patients were encouraged to do rehabilitation exer- cises for functional recovery under the guidance and supervision of orthopaedists.Results All the patients were followed up for 6 to 16 weeks (mean,8 weeks).According to TAM (Total Active Motion) criteria,12 cases were rated as excellent,10 cases as good,6 cases as fair,and 2 cases as poor.The excellent to good rate was 73.3%.The 22 excellent and good cases could perform daily-life activities with affected fingers,such as writing,holding chopsticks and doing and undoing buttons.No patient experienced rerupture.Conclusion In perioperative rehabilitative care for rupture of flexor tendon pollicis longus at ZoneⅡ,it is important to have correct diagnosis,noninvasive and secure suture,safe external fixation and functional exercises under the guidance of orthopaedists.

Carotenoids play an important role in regulating the hydrogen production of hydrogen-producing Rhodobacter sp. The carotenoids of hydrogen-producing Rhodobacter sp. grown in acetate medium were extracted by using acetone-methanol (7∶2,V/V) solvent and were separated by using thin-layer chromatography on silica-gel plate. The qualitative and quantitative of the carotenoids were analyzed by spectrometry. The results showed that the carotenoids were completely extracted three times with acetone-methanol (7∶2,V/V) in two hours. The ultrasonication had little effect on yield of carotenoids. The yield of carotenoids was 2.81mg/g wet cell. There were 4 spots on the silica-gel plate in the order of yellow, red, light red and light yellow. Yellow spot and red spot were the dominant composition of carotenoid in Rhodobacter sp. The spectrometry data showed that the yellow and red component might be the spheroidene and spirilloanthin respectively.

Objective To investigate the clinical and laboratory features of male patients with anti-phospholipid syndrome (APS).Methods Thirty-three male APS patients admitted to Peking University People's Hospital from January 2003 to April 2015 were enrolled.One hundred and fourteen female APS patients were selected as controls.Female patients with thrombosis were analyzed.x2 test, Fisher's exact test and t test were used for statistical analysis.Results Among male patients, 39.4％ were primary APS and 60.6％ were secondary APS.Compare with female patients,the prevalence of venous thrombosis was significantly higher than that in male APS (72.7％ vs 29.8％,x2=19.719, P=0.000).The male APS patients experienced more episodes of thrombosis (75.8％ vs 22.8％, x2=31.669, P=0.000) and not less than two locations of thrombosis than female (69.7％ vs 22.8％, x2=25.321, P=0.000), there was still significant difference between male patients and female patients with thrombosis.There was no difference of antiphopholipid antibodies between the two groups.Conclusion Male patients with antiphospholipid syndrome are more prone to have thrombosis.More clinical interventions should be implemented in male patients with APS.
