Objective:To explore efficacy of the rehabilitative strategy in hospitalized schizophrenics.Method:Sixty-four schizophrenic patients were randomly divided into the intervention group and the control group.Both groups received the anti-psychotics therapy, but the teamwork education,medication management skills training module, symptom management skills training module were only given to the intervention group for ten weeks. And a one-year follow-up was carried out after their discharge from hospital. All subjects were evaluated with the Positive and Negative Syndrome Scale (PANSS), Nurses` Observation Scale for Inpatient Evaluation-30 (NOSIE-30), Insight and the Attitude to Treatment Scale, Social Disability Screening Schedule (SDSS), Morning Side Scale. We also recorded the relapse rate, reemployment rate, and re-hospitalization rate. Result:The clinical outcome of the intervention group was significantly superior to the control group on overall improvement according to PANSS (31.17?3.13 vs 52.34?13.02,7.34?1.08 vs 12.36?4.28,7.76?2.13 vs 13.26?4.50,16.13?1.82 vs 32.17?9.82 ),increase of active factor score of NOSIE-30 (-18.3?3.2 vs 14.4?6.7),and the reduction of inactive factor score of NOSIE-30(9.4?6.2 vs -22.3?7.4).The relapse rate(9.4% vs 54.8%),re-hospitalization rate(3.2% vs 42%),reemployment rate(37.5% vs 9.6%)were also better in the intervention group.Conclusion:The effect of rehabilitative strategy for schizophrenic patients not only improves the symptom, but also their social function.

Objective To evaluate prognostic factors for early bronchopleural fistula after pneumonectomy with non small cell lung cancer,and establish a validated clinical model to estimate the risk of early-BPF.Methods We reviewed the medical records of 429 patients who underwent pneumonectomy for NSCLC at our institution.We used univariate and multivariate analysis to identify potential independent risk factors for early-BPF after pneumonectomy for NSCLC.A model to estimate risk of early-BPF was developed by combining independent risk factors.Results The rate of early-BPF after pneumonectomy for NSCLC was 6.5% (28/429).Three factors were independently associated with early-BPF:neoadjuvant therapy (HR:2.406),bleeding (HR:2.171)and diabetes (HR:1.144).A scoring system for early-BPF was developed by assigning 2 points for each major risk factor (neoadjuvant therapy and bleeding) and 1 point for each minor risk factor(diabetes).Scores were grouped as low (0-1),intermediate (2-3),and high (3),yielding the rate of early-BPF was 14%,27%,and 43%,respectively.Conclusion This clinical model is established on the basis of independent risk factors.This model can be used as a predictive tool for early-BPF after pneumonectomy for NSCLC.

Objective Bronchopleural fistula (BPF) is a common but potentially lethal complication after pulmonary resection.Currently,there is still controversy over the appropriate management strategy for BPF,especially when pleural space contamination develops.The purpose of this study was to evaluate the efficacy and safety of surgical repair fistulas combined with pedicled muscle flaps coverage in patients with early BPF after pulmonary resection based on our experience with 23 cases.Methods The clinical data for 23 patients who underwent surgical repair of early BPF from January 1999 to December 2010 at our hospital were reviewed.Thirteen patients had undergone a prior pneumonectomy and 10 patients had undergone a prior lobectomy.BPF occurred from postoperative day 5 to40 (mean postoperative day 21 ).Nine patients had a contaminated pleural space.After BPF was clearly diagnosed,prompt closed pleural drainage was instituted,followed by surgical repair of BPF.Four patients underwent a direct suture repair of fistula,ten patients underwent stump revision and suture closure,seven patients underwent stump revision and bronchoplasty or carina plasty,and a pedicled muscle flap was sewn to the edges of the fistula in two patients.The stump was covered with various muscle flaps,including interostal muscle flap in five cases,latissimus dorsi muscle flap in ten cases,serratus anterior muscle flap in six cases,and erector spinae muscle flap in two cases.Postoperatively,the pleural space was routinely irrigated and drained.Results No intraoperative or early postoperative death occurred.Four patients developed severs complications,including respiratory failure in two cases,pulmonary embolism in one case,and empyema in one case.All four cases recovered well after treatment.The mean duration of hospitalization was 33 days (range 8 - 120 days ).Surgical repair of BPF was successful in 21 cases (91.3%) but failed for 2 patients..BPF recurrence developed in only one patient two years postoperatively due to stump recurrence.He died of extensive metastatic disease 2 years after BPF recurrence.Conclusion Excellent results can be achieved by early surgical repair combined with stump pedicled muscle flaps coverage in patients with BPF who can tolerate reoperation,even if they have a contaminaled pleural space.

In this study,adults of Armillifer agkistrodontis (A.agkistrodontis) were collected from Agkistrodon acutus,and then the eggs were separated to feed mice.In the next step,when the infection model was established,blood serum of infected mice were collected after 1,2 and 3 weeks,respectively.Furthermore,ELISA and dot- ELISA were used to detect the dynamic change of specific antibodies and circulating antigens respectively.The specific antibodies increased from 8th week,reached the top at 12th week,decreased from 16th week,and then maintain at the same level constantly.Meanwhile,the specific antibodies were typed.It is evident that IgM antibody appeared first.However,it was substitute by IgG1 after 16 weeks.Moreover,the circulating antigens have been detected in the 1st week by dot-ELISA.Then,the dilution between 1:8 to 1:128were founded in 3rd week.The highest dilution with 1:256 appeared at 8th week,maintained before 11th week and then decreased gradually,which might provide a significant clinical implication for early diagnosis of circulating antigens.

Objective To investigate the effectiveness and safety of simultaneous lung volume reduction surgery in the treatment of lung volume mismatch after single lung transplantation. Methods Twenty-four single lung transplantations were performed on 20 male and 4 female patients, with a mean age of 54. 6 ± 12. 2 years (ranging from 28 to 75 years). Indications for transplantation included end-stage chronic obstructive lung disease (COPD) in 14 cases, COPD combined with upper lobe lung destruction in 1 case, COPD combined with pneumoconiosis in 1 case, end-stage interstitial pulmonary fibrosis in 6 cases, lymphangioleiomyomatosis (LAM) in 1 case, and post-transplantation bronchiolitis obliterans syndrom (BOS) in 1 case. Sixteen cases had right-side and 8 cases had left-side lung transplantation. Lung volume reduction surgeries were performed through open thoracotomy. Graft lung volume reduction was carried out through the same incision as transplantation, and native lung volume reduction through a small anterior lateral incision contralaterally. Patients were divided into lung volume reduction group (group Ⅰ) and control group (group Ⅱ). There were 8 cases in group Ⅰ,including 5 graft lung, 2 native lung, and 1 graft and native lung volume reduction surgeries. In group Ⅱ, there were 16 cases that had no further treatment for lung volume mismatch. Differences in various clinical parameters between the two groups were compared. Results Two out of 14 (14.3%) patients with COPD accepted lung volume reduction, which was significantly lower than that in patients with other diseases (6 out of 10, 60%, P<0. 05). Post-transplantation chest X-ray showed that 50.0% and 25% of patients had an undeflected mediastinum in group Ⅰ and group Ⅱ, respectively (P<0. 05).None of the other clinical parameters had significant difference between the two groups (P>0.05).But a tendency of increase in mechanical ventilation, chest tube drainage time, air leak time, volume of chest drainage, and a tendency of decrease in times and volume of thoracentesis could be observed in group Ⅰ. Lung function test was not performed on 8 cases after transplantation. Sixteen cases (4 in group Ⅰ, 12 in group Ⅱ) had complete lung function data. There was no significant difference in FEV1 improvement after lung transplantation between the two groups (P>0. 05). Conclusion Simultaneous graft or native lung volume reduction surgery is a safe and effective way of ameliorating lung volume mismatch after single lung transplantation, probably by improving ventilation-perfusion ratio.

OBJECTIVETo observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB).
METHODSTotally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished.
RESULTSThere was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05).
CONCLUSIONLH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.
