Objective To investigate the significance of anti-SmD1 antibody and other auto-antibod- ies in systemic lupus erythematosus(SLE).Methods Forty-four SLE patients and 136 other rheumatic dis- eases patients were studied.The later group included Sj(?)gren's syndrome,undifferentiated connective tissue disease,ankylosing spondylitis,and rheumatoid arthritis.Immunoblotting was used to measure,the anti-SmD1 antibody,ANuA and anti-SSA60 000 antibody.ANA and anti-dsDNA were detected by indirect immunofluo- rescence,immunodotting was used to measure the anti-Sin antibody.Results The seropositive rate of anti- StuD1 was 47.7% in SLE patients.It was much higher than that of anti-Sm(P

Objective To investigate surgical techniques and results of arthroscopic reduction and fixation for the treatment of avulsion fracture of the posterior cruciate ligament from the tibia through an additional posterolateral portal. Methods An additional posterolateral portal was established by using the inside-out technique under arthroscopic view.After a protective sleeve was placed through the portal and the displaced fracture was reduced,the fragment was fixed by the guide wire drilled through the sleeve temporarily.If the fluoroscopic control showed an anatomic reduction of the fragment and good placement of the wire,the self-attacked cannulated screw and washer was placed intra-articularly over the guide wire through the sleeve for the directive internal fixation of the avulsion fracture.Aggressive rehabilitation programs were recommended postoperatively.Results Except 1 case with 11 mm displacement and rotation of the fragment treated by the arthrotomy after the failure of arthroscopic reduction,the arthroscopic operation was accomplished in all the remaining 10 cases.The operative time was 63～98 min(mean,87.3 min).No injuries of popliteal vessels or nerves occurred.The postoperative X-ray firms showed an anatomic reduction of the fragment and good placement of the screw and washer.With the negative posterior drawer test confirmed by the physical examination,normal range of motion of the injured knee joint and gait were achieved in the 10 patients at 4～7 weeks after surgery.The bone union was confirmed by X-ray films at the 3 months postoperatively.The computer KT-2000 arthrometer measurements of posterior tibial displacement of both knee joints showed side-to-side difference not more than 1.2 mm in 6 patients at 5 months after surgery.Conclusions The additional posterolateral portal can be established by the arthroscopic inside-out technique safely.The displaced fragment of the avulsion fracture of the posterior cruciate ligament from the tibia can be reduced and fixed with the self-attacked cannulated screw and washer arthroscopicly.

Long-term endurance training or physical activity has been confirmed not only to improve physical performance, but to bring about an obvious beneficial effect on human health; however, the mechanism of this effect is not clear. The most studied health adaptations in skeletal muscle response to endurance exercise are increased muscle glycogen level and insulin sensitivity, fiber type transformation toward oxidative myofibers, and increased mitochondrial content/function. Mitochondria are dynamic organelles in eukaryotic cells critical in physical performance and disease occurrence. The mitochondrial life cycle spans biogenesis, maintenance, and clearance. Exercise training may promote each of these processes and confer positive impacts on skeletal muscle contractile and metabolic functions. This review focused on the regulation of these processes by endurance exercise and discussed its potential benefits in health and disease. We presented evidence suggesting that exercise training potentiates not only the biogenesis of mitochondria but also the removal of old and unhealthy mitochondria through mitochondrial quality control.

Objective To analyze the distribution status of soil-transmitted nematodes infection for prevention and treatment.Methods The inquiry field test and grade random sampling were emplyed on a group of people naturally selected in Shanxi Province.The people were examined through pathogen test and statistical diagnosis.Results A total of 7 726 people were investigated.Soil-transmitted nematodes infection rate was 18.86%.Ascaris,enterobius,trichuris,and hookworm was 15.87%,11.46%,0.82%,and 0.04% respectively.The intensity of ascaris infection was 97.74%,1.60%,and 0.66% respectively in light,moderate,and serious conditions,and that of trichuris infection was 88.89%,7.41%,and 3.70% respectively in light,moderate,and serious conditions.Conclusions Soil-transmitted nematodes infection rate is lower than that in 1992.Its cases are mainly distributed in rural areas and schools,closely related to education level.Improving water-drinking conditions and personal hygiene is still key to the prevention and control of the infections.

The genus Myristica (Myristicaceae) consists of 120 species, which were distributed in South Asia, from west Polynesia, Oceania, eastern India to the Philippines. Phytochemical studies showed that 164 compounds including a majority of lignans, along with phenglpropanoids, flavonoids and phenolics, have been isolated from this genus, which exhibited anti-microbial, anti-inflammatory, anticancer, hyperglycemic and hepatic protective activities. This article summarizes research progress of the chemical compositions and their pharmacological activities from this genus, which could provide reference for the in-depth development and utilization of the Myristica plants.
