OBJECTIVESTo evaluate the clinical characteristics, in-hospital and three-year outcome in ST-elevation myocardial Infraction (STEMI) patients receiving conservative treatment (CT), thrombolytic treatment (TT) and primary percutaneous coronary intervention (PCI) in Beijing.

METHODSThis 12-month prospective, multicenter registry study was conducted in 19 hospitals with 808 patients with STEMI in Beijing between Jan. 2006 and Dec. 2006, 518 (64%) received PCI, 106 (16.1%) received TT and 184 (22.8%) received CT therapy. Patients were followed up for 3 years.

RESULTSAt baseline, the age of patients in CT group [(64.5 ± 13.5) years] was significantly higher than those in TT group p(57.9 ± 11.0) years] and in PCI group [ (60.4 ± 12.3) years, all P<0.01]; and the median time from symptom onset to hospital in CT group (207 min) was significantly longer than those in TT group (130 min) and PCI group (130 min, all P<0.01). Emergency Medical Service (EMS) use was significantly higher in PCI group (184/518, 35.5%) than in CT group (46/184, 27.3%) and TT group (29/107, 25.0%, all P<0.05). Health insurance holder was the highest in PCI group (P<0.01). PCI was performed less frequently than thrombolytic therapy [66.6% (345/518) vs. 80.2% (85/106)m P=0.02] during off-hours and more frequently performed in tertiary hospitals than in secondary hospitals[66.8%(437/651) vs. 52.6% (81/154, P<0.01)]. The in-hospital mortality and the cardiovascular mortality at 3 year after hospital discharge was significantly higher in CT group [9.2% (17/185) and 9.4% (15/159)] than in PCI group [3.5% (18/518), 4.5% (20/446)] and TT group [6.6% (7/106), 2.3% (2/86), all P<0.01]. Patients in PCI group had the highest adherence level of aspirin, β-blocker, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers or statins at 3-years follow-up (all P<0.05). Multivariable Cox proportional hazards regression analysis showed that only PCI was associated with lower risk of cardiovascular death (HR-0.40, 95% CI:0.21-0.73, P<0.01).

CONCLUSIONSSocial and clinical setting may affect the physician's decision to provide reperfusion therapy in Beijing for STEMI patients. Better adherence of secondary preventive drugs and lower cardiovascular death are observed in STEMI patients receiving PCI during the 3-year follow-up

OBJECTIVETo study clinical characteristics of children with enthesitis related arthritis (ERA).

METHODSTwelve patients fulfilling the international league of associations for rheumatology (ILAR) criteria for classification of juvenile idiopathic arthritis (JIA) and ERA were referred to our department between August and November, 2002. Their gender, age, family history, clinical manifestations, imaging data, laboratory data and treatment regimens were analyzed retrospectively.

RESULTSOf the 12 patients, 11 were male, only one was female; their age ranged from 4 to 16 years, and the median age was 10.5 years. Ten (83%) of the patients were older than eight years. Among their first degree relatives, one had definite ankylosing spondylitis (AS), and 3 presented with a history of inflammatory low back pain. Enthesitis occurred in 9. Synovitis occurred in 11, most of which were oligoarthritis, predominantly affecting large joints of the lower limbs in an asymmetric pattern. Seven patients underwent CT scan, and only one had erosions of the sacroiliac joints to achieve a diagnosis of juvenile AS. Ten had fever at the onset, and one had a history of diarrhea preceding the symptoms of arthritis. Urethritis and balanitis circinata occurred in 3 cases fulfilling the classification criteria of Reiter's syndrome, with conjunctivitis in 2 and corneitis in one. Elevated inflammatory indicators such as white blood cell, neutrophil, platelet, erythrocyte sedimentation rate, C-reactive protein, immunoglobulins and serum complement C3 were common during the acute illness. Mild anemia was found in 4, and reactive hemophagocytosis in 4 bone marrow specimens. DNA of human parvovirus B19 was detected in sera of 2 cases. One had positive IgM antibody to coxsackie virus B. All 12 cases were rheumatoid factor negative and HLA-B27 positive. Nonsteroidal anti-inflammatory drugs and sulfasalazine were the mainstay of treatment. Corticosteroids were added in 3 cases as a "bridge" therapy due to the severe systemic inflammation. Methotrexate was used in 4 cases with refractory disease or with the hip involved, and in 2 of them cyclophosphamide was added.

CONCLUSIONThe clinical characteristics of ERA can facilitate an early diagnosis so as to avoid joint damage and disabilities.

OBJECTIVETo evaluate the clinical value of the comprehensive therapy of acupuncture, Chinese herbal medicine and rehabilitation in the treatment of post-stroke flaccid limb dysfunction.

METHODSThe four-center, single-blind, randomized and controlled research method was adopted, 240 qualified subjects were randomized into a comprehensive therapy group, an acupuncture group, a rehabilitation group and a Chinese herbal medicine group, 60 cases in each one, at the ratio of 1 1. In the comprehensive therapy group, the comprehensive therapy of acupuncture, Chinese herbal medicine and rehabilitation was applied. The acupuncture therapy included the scale acupuncture at middle line of vertex, lateral line 1 of vertex, lateral line 2 of vertex, etc. with the single reinforcing and reducing technique by the speed of needle insertion and withdrawal, and the body acupuncture therapy at the acupoints on the antagonistic muscles with the reinforcing and reducing technique by the needle rotation. The Chinese herbal medicine therapy included No. 1 stroke formula for the cases of liver and kidney yin deficiency and the upward disturbance of wind yang, No. 2 stroke formula for qi deficiency and blood stagnation, and the stagnation in meridians and No. 3 stroke formula for the interaction of phlegm and stasis and blockage of meridians according to the pattern/syndrome differentiation. The rehabilitation therapy focused on the promotion technique by putting the healthy limb. The simple acupuncture, rehabilitation and Chinese herbal medicine therapies as the comprehensive therapy group were applied in the acupuncture group, rehabilitation group and Chinese herbal medicine group separately. The Chinese medicine symptom, the limb motor function, the daily life activity, fainting needle reaction, allergic reaction and the others were taken as indices to evaluate the efficacy and safety of the treatment.

RESULTS(1) The results of the four indices named the Chinese medicine symptom, the limb motor function, the limb balance function, the daily life activity were all improved significantly after treatment as compared with those before treatment in four groups (all P < 0.01). (2) Concerning to the improvement degrees, the improvements of the above four indices in the comprehensive therapy group were more significant than those in the other three groups (P < 0.01, P < 0.05). The improvement in Chinese medicine symptom in the acupuncture group and the Chinese herbal medicine group were more significant than that in the rehabilitation group (both P < 0.05). The improvement of the upper limb motor function in the acupuncture group was more significant than that in the rehabilitation group and the Chinese herbal medicine group separately (both P < 0.05).

CONCLUSIONThe comprehensive therapeutic program of acupuncture, Chinese herbal medicine and rehabilitation is safe and effective in the treatment of post-stroke flaccid limb dysfunction. It is more advantageous in efficacy as compared with any simple therapy.

OBJECTIVETo summarize methods for repair of claw hand deformity after burn.

METHODSNinety-seven patients with 136 claw hands after burn hospitalized from May 1992 to May 2007 were repaired with skin grafting (104 hands) and transposition of skin flap (32 hands), among which 21 hands were minor-grade, 92 hands moderate, 23 hands severe. The metacarpophalangeal joint was repaired after scar release in dorsum of hand with manual extraction reduction, release of collateral ligament and joint capsula, separation of adhesion in joint, tendon lengthening for obvious contracture. Restitution of finger flexion deformity, lysis of adhesion and grafting among first web and finger webs, repair of central slip extensor tendon or phalangeal arthrodesis were performed according to the abnormal condition after lysis of dorsal scar of hand. The metacarpophalangeal joint from 31 patients were not repaired with above methods for severe finger flexion deformity, their palmar scar were loosened and transplanted firstly, then scar in dorsum of hand were loosened, metacarpophalangeal joint were repaired, flap or skin were transferred or transplanted. General rehabilitation were performed routinely after operation.

RESULTSThe ending of flaps (4 hands) due to the scar were necrosis after transposition and healed through dressing change, other skins or flaps all survived. Most articular deformities were corrected completely or basically. Functions including palmar opposition, grasp were also recovered with satisfactory results.

CONCLUSIONSkin transplantation and transferring of skin flap with overall planning and individual isatin are the key points for repair of claw hand after burn.

OBJECTIVETo investigate the influence of succinic acid on the apoptosis of polymorphonuclear neutrophil (PMN) in human peripheral blood, and to explore its role in infection.

METHODSPMNs were incubated in vitro, and its concentration was adjusted to 5 x 10(6)/mL. Then the cells were divided into normal control group and 5,10, 20, 30 mmol/L succinic acid groups according to different concentrations of succinic acid added into the medium. The supernatant of the cultures in each groups were collected to determine the superoxide content. 1 mL cell suspension was collected from 5, 20 mmol/L succinic acid groups before treatment and at 2, 4, 6, 8, 10 post-treatment hours (PTH) for the determination of caspase-3 activity and the apoptosis rate.

RESULTSThe content of superoxide in 5, 10, 20, 30 mmol/L succinic acid groups (0.437 +/- 0.056, 0.432 +/- 0.024, 0.395 +/- 0.049, 0.386 +/- 0.010) was significantly lower than that in control group (0.505 +/- 0.028, P < 0.05). The caspase-3 activity in each group increased along with the incubation time, but was in lower concentration in 5 mmol/L succinic acid group and in higher concentration in 20 mmol/L succinic acid group when compared with that in control group (P < 0.05). The apoptosis rate of PMN in control group was (6.1 +/- 1.1)% before incubation, and it reached (13.2 +/- 2.0)% at 2 PTH, and (27.7 +/- 3.7)% at 10 PTH. The apoptosis rate of PMN in 5 mmol/L succinic acid group was lower than that in control group except that at 4 PTH (P < 0.05). On the other hand, the apoptosis rate in 20 mmol/L succinic acid group (during 4-10 PTH) were obviously higher at each time points compared with the control group (P < 0.05).

CONCLUSIONLow concentration of succinic acid can suppress the apoptosis of PMN, while high concentration of succinic acid has an opposite effect. It is known that bacteria can produce succinic acid.

OBJECTIVETo study the proteomic change in lymphocytes of rabbits with scald injury and Staphylococcus aureus (SA) invasion.

METHODSTwenty-four rabbits were divided into four groups as follows: control group, scald group, scald with SA invasion 2 hs group, and scald with SA invasion 6 hs group, according to random number table, with 6 rabbits in each group. Except for rabbits in control group (sham scald at 37 degrees C), rabbits in the other 3 groups were subjected to 30% TBSA full-thickness scald. Rabbits in SA invasion 2 and 6 hs groups were injected with 2 mL (1.0 x 10(8) CFU/mL) SA suspension, which was in the log growth phase, via auricle vein 18 hs and 22 hs after injury. Whole blood samples were collected from carotid artery of rabbits in 4 groups 24 hs after scald. Lymphocytes were isolated and its extracted proteins were analyzed by two-dimensional gel electrophoresis coupled with mass spectroscopy.

RESULTSAbout 1030 protein spots of lymphocytes were detected in each group. Compared with that of control group, 19 protein spots were found to be differentially expressed in the other 3 groups, and 11 spots (10 proteins) were identified. Expression levels of cofilin, cyclophilin A, ubiquitin, nucleoside diphosphate kinase, glutamate dehydrogenase and annexin 1 were down-regulated, but expression level of peroxiredoxin was up-regulated obviously.

CONCLUSIONSThere is obvious proteomic change in lymphocytes of scalded rabbits or of scalded rabbits invaded by SA, and it may relate to immune suppression and sepsis after injury.

OBJECTIVETo establish an effective way for rapid identification of Monascus strains based on DNA molecular marker.

METHODA random amplified polymorphic DNA (RAPD) marker named F421 in genomic DNA of Monascus F strain was observed during a comparison of DNA fingerprints derived from 10 cultivated strains of Monascus. F421 was cloned and sequenced. Comparing the sequence of F421 (GenBank accession number EF063107) with other relative sequences in the GenBank databases, no distinct comparability was found. A pair of sequence characterized amplified region (SCAR) primers were designed based on the sequence of the cloned fragment and tested for the specific detection of Monascus F.

RESULTThe results of polymerase chain reaction showed that only a 421bp segment of Monascus F strain was amplified compared with other 9 cultivated strains of Monascus. And the acquired SCAR marker of strain F could be used as a specific DNA fingerprint to identify Monascus strain F within one day.

CONCLUSIONSCAR molecular marker technology is an effective new way to identify Monascus strains more rapidly. And also is an assistant tool to identify Monascus strains more accurately when disagreements come out using traditional classification. It could be applied widely to the protection of germ plasm resources, classification and identification distinguishing false strains of pharmaceutical fungi.

OBJECTIVETo study the role of Bcl-2 and Bax protein contents and their gene expression in Al-induced neurons apoptosis.

METHODSNeurons from 0 - 3 day rats were cultured and treated with different concentrations of AlCl(3 x 6) H2O. The cell apoptosis was observed by the TUNEL method and under the scan electron microscope. Bcl-2 and Bax protein contents were detected by the immunochemistry method while their gene expressions were measured by the RT-PCR method.

RESULTS(1) DNA fractions in the TUNEL method increased with the rising aluminum concentration. Blebbings and apoptosis bodies on the surface of the neurons were clearly observed under the scan electron microscope. (2) Bcl-2 protein contents and their gene expression decreased with the rising aluminum concentration (P < 0.01, r = -0.695; P < 0.05, r = -0.647), while Bax increased at the same time (P < 0.01, r = 0.676; P < 0.01, r = 0.794), the value of Bcl-2/Bax was related with the aluminum concentration (P < 0.01, r = -0.655; P < 0.01, r = -0.777).

CONCLUSIONThe aluminum may induce neurons apoptosis. Bcl-2 and Bax protein contents and their gene expression may play an important role in Al-induced apoptosis.
