Objective To investigate the effects of percutaneous coronary interventional therapy on platelet activation and the systemic fibrinolysis in patients with coronary artery disease (CAD).Methods The plasma concentration of platelet alpha granule membrane glycoprotein 140 (GMP 140), plasminogen activator inhibitor 1(PAI 1), tissue type plasminogen activator (t PA), von Willebrand factor (vWF) and D dimer (D D) of the blood sampled from vein according to the schedule were measured by ELISA. Results In the sixty five patients with CAD, at 10 minutes after the procedure, plasma levels of GMP 140, t PA and D D were significantly higher than the previous ones; and at 24 h, plasma levels of PAI 1 and vWF were also increased significantly. Conclusions The activation of platelet and impaired fibrinolytic activity were occurred after PCI in the patients with CAD.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.

OBJECTIVETo observe the effect and safety of plastering Chinese Compound Shenhuang Ointment (CSO) at Shenque (RN8) in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of qi stagnation blood stasis syndrome (QSBSS).

METHODSA prospective, multi-centered, randomized, double-blinded, controlled trial was conducted in 220 postoperative gastrointestinal dysfunction patients of QSBSS. They were randomly assigned to two groups, the CSO group (110 cases) and the placebo group (110 cases). CSO was plastered at Shenque (RN8) for 5 days after operation. The time of exhaustion, defecation, the recovery of intestinal peristalsis, integrals of TCM syndrome, and serum levels of motilin (MOT)and somatostatin (SS) were observed.

RESULTSCompared with the placebo group, the condition of exhaustion and defecation, the recovery of intestinal peristalsis on the 3rd day after operation was all improved (P < 0.05). The integrals of TCM syndrome at day 2, 3, and 4 were more significantly lowered in the CSO group than in the placebo group (P < 0.01, P < 0.05). The total effective rate of TCM syndrome was 95.3% in the CSO group, better than that in the placebo group (91.8%, P < 0.05). Compared with the placebo group, the serum MOT level increased and the serum SS level decreased at day 5 after operation in the CSO group (P < 0.05).

CONCLUSIONSThe plastering of CSO at Shenque (RN8) could advance the time of exhaustion and defecation, and improve patients' clinical symptoms. And patients could tolerate well.

Objective In patients with pulmonary atresia and intact ventricular septum ( PAIVS) without right ventricular-dependent coronaries, catheter techniques including the use of a sniff wire, lasers, and radiofrequency have been the most widely used initial therapy. However, percutaneous perforation and balloon valvuloplasty were associated with higher rate of procedural failure and serious complications. Methods We report our experience with a hybrid approach for pulmonary atresia with intact ventricular septum, combining surgery and interventional catheterization techniques. Between March 2005 and March 2010, hybrid procedure was carried out successfully in 30 newboms and infants with favorable anatomy. The age ranged from 1 day to 48 months with a mean of (4.59 ±3.21) months. The heart was exposed through median sternotomy. A pursestring suture was placed in the right ventricular outflow tract 2 cm away from the pulmonary trunk. Then a 16-gauge intravenous catheter was punctured through the right ventrical and perforated the atretic PV with the guidance of echocardiography. A guide wire was then inserted into the sheath and used to guide the balloon across the PV. Sequential dilations were performed until a full opening of the PV with the guidance of epicardial echocardiography. In patients ＜ 3 months PDA ligation was performed followed by modified Blalock-Taussig (B-T) shunt. In patients ＞ 3 months PDA ligation was not performed. A modified B-T shunt was inserted if severe systemic oxygen desaturation occurred after PDA ligation. Bidirectional Glenn shunt was performed for severe hypoplasia. Hybrid procedure was achieved in all patients. The simultaneous procedures included 25 cases of PDA ligation. 6 newborns underwent modified B-T shunt placement (3.5 to 5 mm) after pulmonary valvuloplasty and PDA ligation, and 2 patients ＞ 1 month underwent modified B-T shunt. Another 2 patients were selected for univentricular palliative surgery because of a diminutive monopartite right ventricle and bidirectional Glenn procedure was performed. No pericardial effusion or cardiac tamponade was observed in all patients. Another case without PDA ligation underwent a modified B-T shunt because of hypoxemia three days after hybrid procedure, and the rest patients were discharged without any further surgical intervention.During the follow-up period of 1.5 to 62.0 months, 5 patients died. 25 (83.3%) survived and were all in New York Heart Association functional class 1. Peripheral oxygen saturation increased from 0.73 ± 0.08 to 0.94 ± 0.04 (P ＜ 0.05). One patient remains in a single-ventricle pathway, whereas 24 patients achieved a two-ventricle circulation. Results Conclusion Perventricular balloon pulmonary valvuloplasty using a hybrid approach is a safe and feasible procedure for patients with PAIVS.

Objective To evaluate diagnostic value of X-ray computed tomography(CT) neck masses in children.Methods Clinic,pathologic diagnosis and CT scans of 26 patients from Jan.2004 to Jun.2006 with neck masses which location,density,edge and near construction were reviewed retrospectively.Results Seven cases in neck anterior area,13 cases in neck lateral area,6 cases in other areas or unconfirmed.Eight cases with lower density than cervical muscles,2 cases with same density,2 cases with higher density,14 cases with mixed density.Inflammatory masses were observed in 13 cases,congenital malformation in 11 cases,thyroiditis in 1 case,pharyngeal tumor-like proliferation in 1 case.Conclusion CT scan is the best choice of diagnosis of neck masses in children,and is valuable to diagnosis associated with history and physical examination.

In the process of acid hydrolysis of medical absorbent cotton, we have discovered that some of the domestic manufactured medical absorbent cotton is mixed with wasted non-cotton chemical fiber. If the cotton is used in medical treatments, the chemical fiber will cause irritation, allergy and inflammation, so it's very harmful. But the non-cotton fiber content is not stipulated in the standard of YY0330-2002, and no testing method for it is available. In this paper we discuss the existent quality problems, the control and the test method for non-cotton chemical fiber in medical absorbent cotton.

Objective To discuss the midterm results of modular femoral prosthesis in total hip revision surgery for bone defects.Methods From December 2001 to June 2006,by using Link-MP modular femoral prosthesis for muhiple reasons(48 with asepsis loosening,seven with infections using two-stage revision procedure,one with fracture of proximal femur and one with periprosthetie fracture), total hip revision surgery was carried out in 56 eases including 24 males and 32 females with age range of 38-77 years(mean age 58.8years).Causes for revision included sterile prothesis loosening in 48 cases, infection of hip prosthesis in seven and peripheral fracture of femoral stem fracture prosthesis in one.Re- vision for infected femur was all at stageⅡ.Of 56 cases with femoral stem prosthesis loosening,30 had loosening of primary cemented prosthesis and 26 of uncemented prosthesis.According to the Mallory bone defect classification,five eases were with typeⅡbone defect,21 with typeⅢA,28 with typeⅢB and two with typeⅢC.Bone grafting was performed in 12 cases and wire or cable cerelage in 28.Fracture of great trochanter was found in two cases,fracture of femoral stem in three and perforation of femoral stem in one.Results A total of 52 eases half year after operation were followed up for mean 31.78 months (8-56 months).No migration of distal femoral stem was found in all eases except for one ease had 1.5 cm subsidence of proximal femoral stem.The Harris hip score was preoperative 46 scores(21-52)and post- operative 89(79-94).There found no significant limb discrepancy,thigh pain or dislocation.Conclu- sions Total hip revision surgery for femoral bone defect using modular femoral prosthesis has optimal midterm result especially in its advantages of regulating limb length,offset,anteversion,which can help us match the proximal femur with distal femur and achieve initial and long-term stability.

Objective To study the macrophage colony-stimulating factor(M-CSF)expression levels of serum and synovial fluids from patients with spondyloarthropathy(SPA)and its contribution to the pathogen- esis of SpA.Methods Eleven SpA synovial tissue samples were compared to those from peripheral blood mononuclear cells(PBMC)of 10 normal subjects using a 1176 gene array.M-CSF was detected in both serum samples and synovial fluids by enzyme linked immunosorbent assay(ELISA).Two groups of AS subjects were tested.The first group consisted of 41 ankylosing spondylitis(AS)patients who had not been treated with bio- logics.The second group consisted of 13 subjects whose serum samples were collected before and 14 weeks af- ter initiation of infliximab.These were compared to serum samples from 28 normal subjects,and synovial fluid samples from 15 SpA patients.Results Expression of M-CSF could be detected in both serum samples and synovial fluids.The concentration of M-CSF in the group of 41 AS patients not treated with biologics correlated with the Bath Ankylosing Spondylitis Disease Activity Index(BASDAI)values(r=0.41,P=0.004).Treatment of infliximab in AS patients led to a significant decrease in the values of BASDAI(P=0.000 07),but no signif- icant change in the serum M-CSF values.Conclusion M-CSF is a promising candidate for research on the mechanisms of SpA and its signaling on pathway in SpA is different from tumor necrosis factor(TNF)-?,and it may provide new basis for developing new anti-biologics for SpA.
