Objective To investigate effects of the complex therapy on severe inhalation injury. Methods The cases with inhalation injury and acute respiratory failure (ARF) of 4172 consecutive burn patients from Jan. 2000 to Feb. 2003 in our institute were studied retrospectively. Results 30 of the 128 patients with inhalation injury occurred acute ARF. 48 hours after the exogenous pulmonary surfactant (PS) was used to treat 6 cases with uncomplicated ARF, pulmonary function obviously ameliorated as compared with routine therapy. PaO 2 /FiO 2 rose from 239?33 mmHg to 317?28 mmHg(P

Objective To investigate the feasibility of laparoscopically assisted anorectal pull-through in the repair of high imperforate anus. Methods Four infants (3 boys and 1 girl, age range, 1 d～90 d) with high imperforate anus entered this study. During operations, the rectum was exposed via laparoscope down to the rectourethral fistula, which was ligated and dissected out laparoscopically; and then, by way of a passage through the center of pelvic floor musculature, the rectum was exteriorized to the perineum to perform anorectal anastomosis. Results Laparoscopically assisted anorectal pull-through was successfully performed in all the 4 cases as a primary procedure. The mean duration of the laparoscopy was 71 8 min (range, 45 min～90 min) and the mean blood loss 8 3 ml (range, 5 ml～20 ml), no blood transfusion required and no intraoperative complications occurred. All patients recovered uneventfully. In 3～12 months of follow-up, 1 patient was found anal stenosis at 1 month after the operation and was cured with secondary anorectoplasty. No postoperative complications were seen in the other 3 cases. By now, all the 4 patients have normal fecal continence. Conclusions Laparoscopically assisted anorectal pull-through is an effective technique in the repair of high imperforate anus. Experience has shown that this approach offers minimally invasive wounds, excellent visualization of the rectal fistula and accurate identification of the center of pelvic floor musculature.

Objective　To study the effect of acute serious smoke inhalation injury to unilateral lung on contralateral lung and the therapeutic efficacy of massive bronchoscopic lavage with saline to the primary injured bronchoalveolus at early stage after smoke inhalation on mitigating the secondary damage of the other lung and so as to confirm the therapeutic validity of lung lavage to smoke inhalation injury. Methods　Fifteen mongrel dogs were insufflated with sawdust smoke into left lung and then randomized into 2 groups. The dogs in group A were maintained intravenous glucose saline transfusion and breathed air freely for 24 h after injury. Those in group B received a massive bronchoscopic lavage with 250 ml of saline to injured lung at 1 hour after injury and then were administrated similarly to those in group A. Gas exchange function of bilateral lungs in the process were observed and pathologic and phyiopathologic changes of the lung specimen were examined after the process. Results　While the total lavaging volume was kept to 250 ml, the liquid volume remained in left lung after each operating was from 90 ml to 140 ml. All animals had a significant decline in pulmonary function after smoke inhalation injury. PaO2 in group B decreased significantly soon after the lavage and then increased gradually to exceeding that in group A. The left lung showed serious edema similarly in two groups but in right lung the water content was less, dynamic and static compliance was more in group B than in group A. Conclusion　Bronchoalveolar massive lavage at early post-injury stage to injured lung after unilateral lung smoke inhalation injury can mitigate secondary damage of the non-injured lung. Lung lavage can decrease the intensity of secondary systemic inflammatory reaction and show a therapeutic validity to smoke inhalation injury.

Objective To study the effect of transcranial ultrasound (US) on arterial recanalization in acute ischemic stroke patients.Methods Patients with acute middle cerebral artery (MCA) main stem occlusion after 6 h were randomized into a target group receiving low-frequency,pulse-wave mode,transcranial US for 30 min or a control group.All were treated with intravenous urokinase for thrombolysis.Transcranial doppler sonography (TCD) was used to document vascular occlusion and confirm recanalization at 2 h and 24 h after treatment,and the patients were evaluated using the National Institutes of Health Stroke Scale ( NIHSS).Results Recanilization (complete or partial) after 2 hours was significantly higher in the US group (44.4％) compared with the control group ( 10.5％ ).Recanalization had occurred in 50％ of the US group 24 hours after treatment compared with 15.7％ of the controls.At 2 h after treatment,33.3％ of the US group and 5.5％ of the controls had improved at least 4 points on the NIHSS assessment.After 24 hours the figures were 44.4％ and 10.5％.After 3 months,11 subjects from US group (61.1％ ) had a modified Rankin score ≤2 compared with 4 subjects (21％) from the control group.Conclusions In acute ischemic stroke,transcranial US has positive effects on recanalization and neural function.

Objective: To observe the effect of sequential colon dialysis in patients with chronic renal failure(CRF) in early and medium stage.Methods: One hundred and forty-two CRF patients in early and medium stage were treated with sequential colon dialysis and traditional Chinese medicine according to(traditional) Chinese medical syndrome differentiation and typing,and clinical syndromes were observed.(Sixty-three) patients with CRF were selected as controls treated with low protein diet plus essential amino acids.The serum levels of blood urea nitrogen(BUN),creatinine(Cr),uric acid(UA),the creatinine(clearance) rate(CCr),electrolyte and medium molecular substance(MMS) were measured before and after treatment.Results: The clinical symptoms of the 142 patients were improved,the serum levels of BUN,Cr,UA and MMS were decreased significantly(BUN:(15.3?4.5)mmol/L vs.(8.6?3.3)mmol/L;Cr:((443.6?73.5)?mol/L) vs.(283.5?38.7) ?mol/L;UA:(512.6?86.5)?mol/L vs.(243.1?33.6)?mol/L;MMS: 0.44?0.06 vs.0.32?0.04),and CCr increased markedly((9.87?3.31)ml/min vs.(15.60?(4.63)ml/min)).The difference between treatment group and control group was significant.The changes in electrolyte levels were not significant before and after treatment in both groups.Conclusion: Sequential colon dialysis has obviously curative effects on CRF patients in early and medium stage,and could ameliorate the(develope) of CRF in early and medium stage.

Objective To explore the ultrasound characteristics of carotid atherosclerosis in acute stroke patients with early neurological deterioration (END). Methods END was defined as a increase by at least two points in the National Institutes of Health Stroke Scale between admission and day 7. Among 128 patients with acute stroke in whom carotid ultrasound examinations were performed within 24 hours after admission, 38 patients with END and 40risk-matched patients without END were included in the END group and the non-END group,respectively. The ultrasound characteristics of carotid atherosclerosis were compared in both groups. Results Plaque score (16.7 ±4.4 mm vs. 13.3 ±3.5 mm, t=2.673, P=0.009),intima-media cross-sectional area (26. 4 ± 8. 5 mm2 vs. 20. 5 ± 6. 8 mm2, t = 3. 394, P =0. 001), arterial stiffness index (28. 94 ±4. 29 vs. 21. 22 ±5. 85, t = 6. 618, P =0. 000), and the rates of unstable plaque (66. 7% υs. 43. 3%, χ2=9. 164, P =0. 003), eccentric plaque (62. 8% vs. 45. 6%, χ2=5. 008, P =0. 025), stenosis ≥50% (71. 1% vs. 37. 5%, χ2=8. 828, P =0. 003), and negative remodeling (28. 9% vs. 7. 5%, χ2=6.087, P =0.014) in the END group were significantly higher than those in the non-END group, while the distensibility coefficient ([14. 74 ±8. 66]×10-6/P υs. [19. 16 ±9.35] × 10-6/Pa, t =2. 163, P=0. 034)and compliance coefficient ([0.49 ±0. 13] × 10-4 mm2/Pa υs. [0. 58 ±0. 11] × 10-4 mm2/Pa,t =3.307, P =0. 001) were significantly lower than those in the non-END group. Conclusions The ultrasound characteristics such as plaque score, intima-media cross-sectional area, arterial stiffness index, unstable plaque, eccentric plaque, stenosis ≥ 50%, negative remodeling,distensibility and compliance may be useful to predict END in patients with acute stroke.

Anxiety disorder is one of the most common mental disorders and seriously impairs the physical and mental health of patients. Due to the efficacy of acupuncture for tranquilization, acupuncture displays its unique advantage on the treatment of anxiety disorder, but the relevant biological mechanism has not been elaborated. The modern medicine study has proved that the heart and brain have their own independent natriuretic peptide (NP) system. The dysfunction of ANP and its receptor are closely related to the occurrence of anxiety disorder. The ANP acts on anti-anxiety. Hence, focusing on the three aspects, named the anti-anxiety effect of acupuncture based on its tranquilizing effect, the anti-anxiety effect of ANP and the positive regulation of acupuncture on NP, the mechanism on ANP and its receptor was explored in anti-anxiety with acupuncture based on tranquilizing effect, and the idea was put forward on that the anti-anxiety effect of acupuncture was possibly based on its action of tranquilization through regulating the ANP and its receptor. As a result, it is expected to provide the theoretic support for the mechanism study on anti-anxiety with acupuncture based on its tranquilizing effect.
