Objective To evaluate the safety of surgical procedures for patients after heart valve prosthesis implantation.Methods Clinical data of 12 cases with heart valve prosthesis implantation undergone other surgical treatment from November 1996 to December 2005 were retrospectively analyzed.All the cases had routine oral warfarin with prothrombin time (PT) of 20.0—28.3 s averaged 23.5 s, international normalized ratio (INR) for prothrombin of 1.79—2.23 averaged 1.95 and heart functional class Ⅰ—Ⅲ.Among them,appendectomy was performed in three cases with acute appendicitis,reposition and repair in one with inguinal hernia,radical gastrectomy in two with gastric carcinoma,left hemicolectomy in one,cholecystectomy in three,left femoral head replacement in one,and bilateral high ligation and ablation of great saphenous vein in one.Elective surgical operation was performed in seven cases,and emergency operation in five.In those with elective surgery,warfarin was stopped 2—3 days before operation,while 5—10 mg vitamin K_1 was injected intramuscularly 6—8 hours before emergency surgery with preoperative median PT of 15.1 and 15.3 s and median INR of 1.24 and 1.30,respectively.In operation,5—10 mg vitamin K_1 were injected intravenously into the patients by drip depending on their bleeding on the surface of wound.ECG,blood pressure,hemoglobin and oxygen saturation were routinely monitored for all the cases intraoperatively and postoperatively.For the cases with heart function above class Ⅱ,fluid infusion was adjusted based on intubated central venous pressure,and for those with general anesthesia,analyses of blood gases and electrolyte were monitored routinely in operation.Results OPeration time averaged 20—160 rain in all the 12 patients,with blood loss 5—280 ml in average and without complications of massive hemorrhage,thrombosis and heart failure.Conclusions Surgical operation was safe for patients with heart valve prosthesis implantation,if preoperative PT and INR were adjusted to about 15 s and 1.30,respectively by cessation of warfarin or application of vitamin K_1,combined with careful manipulation and strengthened perioperative management.

OBJECTIVETo investigate the regulation of Toll-like receptors (TLRs) on immune suppressive cytokines in situ colon cancer cells.

METHODSThe mRNA and protein expression spectrum of TLRs in HT-29 cells were determined by RT-PCR and Western blot respectively. The cytokines and chemokines levels of supernant of HT-29 stimulated by lipoplysaccharide(LPS) were detected with ELISA.

RESULTSTLR1-9 were expressed in HT-29 cells on mRNA level. After LPS stimulation, TLR4 mRNA and protein expressions were up-regulated in HT-29 cells, and TGF-beta, VEGF, IL-8, CCL20 and IL-6 levels increased significantly(all P<0.01). Except IL-6, up-regulation of the other cytokines was not suppressed by NF-kappa B inhibitor.

CONCLUSIONTLRs expressed on colon cancer cells may elevate the immune suppressive cytokines and chemokines, which promote the immune escape of cancer cells.

OBJECTIVETo observe the protection of Qingyuan Shenghua Decoction (QSD) on multiple organs of sepsis patients after bone trauma, and to preliminarily explore its mechanism.

METHODSTotally 60 sepsis patients after bone trauma were randomly assigned to the treatment group and the control group according to random digit table, 30 in each group. All patients received routine Western medical treatment. Patients in the treatment group additionally took QSD or were nasally fed with QSD, one dose per day for 1 week. Changes of WBC, oxygenation index (PaO2/FiO2), serum creatinine (SCr), total bilirubin (TBIL), aspartate aminotransferase (AST), fibrinogen (FIB), D-dimer (DD), activated partial thromboplastin time (APTT), pro-calcitonin (PCT), C-reactive protein (CRP), heart rate (HR), mean arterial pressure (MAP), intra-abdominal pressure, scores for Acute Physiology and Chronic Health Evaluation II (APACHE II), sequential organ failure assessment (SOFA) scores were observed before treatment and on day 1, 3 and 7 after treatment.

RESULTSCompared with the control group at the same time point, MAP increased at post-treatment day 1 and 3; CRP, APTT, HR, SCr, TBIL, AST, intra-abdominal pressure at post-treatment day 3 obviously decreased in the treatment group (P < 0.05, P < 0.01). WBC, SOFA scores, PCT, CRP, APACHE II, APTT, D-D, HR, SCr, TBIL, AST and intra-abdominal pressure significantly decreased; FIB, MAP and PaO2/FiO2 obviously increased at post-treatment day 7 (P < 0.05, P < 0.01).

CONCLUSIONQSD had good protective effect on multiple organ function in sepsis patients after bone trauma, and its mechanism might be related with effectively clearing endotoxin, alleviating inflammatory reactions, and fighting against coagulation dysfunction.

OBJECTIVETo evaluate the efficacy and safety of autologous peripheral blood stem cell transplantation (auto-PBSCT) after high dose melphalan in patients with POEMS syndrome.

METHODSNine patients including 6 males and 3 females received 10 auto-PBSCT after high dose melphalan in our hospital from June 2005 to October 2009. The median age at transplantation was 44 (39 - 48) years. The median time from onset of disease to transplantation was 12 (5 - 60) months. Peripheral stem cells were mobilized by G-CSF alone in one patient and 8 patients by G-CSF plus chemotherapy. Two patients were conditioned by melphalan 140 mg/m(2) and 7 by melphalan 200 mg/m(2). The median number of MNC was 3.75 (1.05 - 8.33) × 10(8)/kg, and that of CD34(+) cell was 5.37 (1.32 - 10.90) × 10(6)/kg.

RESULTOne patient received tandem auto-PBSCT and others received single one. Stem cell engrafted in all but 1 patient who died of severe infection and acute renal failure on day 9 after transplantation. Eight patients were evaluable for response. The median time to ANC ≥ 0.5 × 10(9)/L and platelet ≥ 20 × 10(9)/L was 10 (9 - 11) and 11.5 (9 - 14) days respectively. Two patient reached negative immunofixation electrophoresis (IFE) after stem cell mobilization and transplantation respectively, and the other 6 remained IFE postive after auto-PBSCT. Skin changes and edema of lower extremities were improved in 5 of 6 patients, lymphadenopathy relieved in 1 and papilledema improved in 2 of 3 patients. All but 1 patient achieved gradual neurologic improvement after transplantation.

CONCLUSIONPBSCT is an effective and safe therapy for POEMS syndrome patients with low treatment related mortality.

Objective: To evaluate the efficacy of the third-generation instrumentation including TSRH, CD and ISOLA in the treatment of adult scoliosis. Methods:Thirty-five adult patients with idiopathic or degenerative scoliosis who received treatment with third-generation instrumentation (TSRH,CD and ISOLA) between July 1999 to January 2003 were retrospectively reviewed. The mean preoperative cobb angle of major curves of the frontal plane was 58.1°(42°-95°). The patients received a combined anteroposterior approach or a single posterior procedure. The mean follow-up time was 20 months(10-48 months). Preoperative and postoperative Cobb angles of the frontal plane and sagittal plane and the distance between C7 and CVLS were measured. The subjective assessment was judged by questionnaire. Results: Postoperative clinical appearance of all patients improved significantly. Mean correction of major curves of the coronal plane was 53.2%. Mean loss of correction of the coronal plane in the last follow-up was 4.3°. The distance between the midline of C7 and CVSL was corrected from 2.6 cm to 0.24 cm. The results of follow-up showed that 89.3% patients were satisfied with the outcome. Pneumatothorax and haematothorax occurred in 2 patients. Three patients still complained of low back pain one year after operation because of adjacent degeneration in 2 patients and pseudoarthrosis in the remaining 1 patient. Conclusion: Imageologic findings and subjective assessment of the patients showed that the third-generation instrumentation can achieve good correction and trunk balance in the treatment of adult scoliosis with fewer complications.

Objective: To study the biocompatibility of CFR/PEEK composite in bone tissue after implanted in lumbar intervertebral space and to evaluate its role in the interbody fusion compared to the allograft bone. Methods: Thirteen beagles were chosen among which 7 were implanted with the disk-like CFR/PEEK composite in the lumbar intervertebral space and the other 6 were implanted with allograft bone. X-ray, QCT and histological examination were employed at 6, 12 and 24 months postoperatively. Results: The X-ray results of fusion segment were in conformity with the QCT's as well as that of histological results. All animals obtained a complete fusion at 24 months. Histological examination revealed that the anterior soft tissue to the implant exhibited a nonspecific foreign body reaction with connective tissue embed the biomaterials. Carbon fragment were seen in the surrounding tissue and some of the debric were phagocytosed by foreign body giant cell. Histological examination of bone and material revealed that new bone grew along the hole of CFR/PEEK implant. Conclusion: CFR/PEEK has an excellent biocompatibility to bone tissue.

OBJECTIVETo analyze efficacy of radiotherapy for adult patients with Langerhans cell histiocytosis (LCH).

METHODSClinical features and efficacy of radiotherapy for biopsy-proven adult patient with LCH from January 2000 to October 2012 in our hospital were retrospectively analyzed.

RESULTSSeventeen (11 male and 6 female) adult LCH patients with a mean age of 31 (18-56) years old were treated by irradiation, all patients presented as single-system disease. The mean duration from diagnosis to irradiation was 8.3 (0-108) months. Although 12 of 17 patients (70.6%) had short-term response to radiotherapy, all patients but one (94.1%) progressed during long-term follow-up, the mean progression-free survival (PFS) was 14 (0-131) months. Of the progressed patients, one relapsed in situ, the remaining 15 patients progressed outside the irradiated region. Thirteen patients (76.5%) eventually progressed to multisystem disease.

CONCLUSIONThough radiotherapy for LCH in adults produced a high short-term response up to 70.6%, most of patients eventually progressed in situ or outside the irradiation region during long-term follow-up.
