Objective To analyze and explain how to treat 1 patient with post-ERCP hemobilia based on best clinical evidence. Methods We used EST and EPBD, ENBD, Hemobilia as key words to search MEDLINE （1978 ～ 2004） and CBMdisc（1978 ～ 2004） to find the best clinical evidence and evaluated the quality of evidence. Results According to the evidence, we found that endoscopic papillary balloon dilation （EPBD） or endoscopic nasobiliary drainage （ ENBD ） may be more effective and better tolerated in the treatment ofpost-ERCP hemobilia. Our patient did not receive sufficient medical treatment after hemobilia. He was not given a general assessment before surgery including liver function tests. As a result, the patient died of liver failure and its complications. Conclusions We should treat such patients promptly and efficiendy after hemobilia. We should also evaluate their general condition properly before the operation.
Objective To investigate the incidence and risk factors of non-alcoholic fatty liver disease (NAFLD) in patients with myocardial infarction. Methods A total of 634 patients with myocardial infarction from Beijing Anzhen Hospital were asked to take liver and gallbladder ultrasonography during hospitalization, and then divided into the NAFLD and non-NAFLD groups. The incidence and risk factors of the two groups were then analyzed. Results The incidence of NAFLD was 52.2% (331/634). Both body mass index (BMI) and serum alanine aminotransferase of the NAFLD group were higher than those of non-NAFLD group, with significant difference (Plt;0.05). The incidence of NAFLD was positively increased following the severity of coronary diseases (χ2=7.275, P=0.03). The result of multivariable logistic regression analysis showed BMI, multi-vessel lesions of coronary disease, and left main coronary artery lesion were the independent risk factors of NAFLD. Conclusion The myocardial infarction patients who are particularly complicated by overweight, multi-vessel lesions and left main coronary artery lesion have a higher incidence of NAFLD.
Abstract: Objective To summarize the immediate effects and the near and midterm followup results of transthoracic balloon valvuloplasty for newborns and infants with severe and critical pulmonary valve stenosis to find out an effective plan for onestop balloon valvuloplasty. Methods From March 2006 to March 2010, 32 patients including 23 males and 9 females with severe and critical pulmonary valve stenosis were treated in Fu Wai Hospital. Their age ranged from 5 days to 11 months (4.59±3.21 months). Weight of the patients ranged from 2.3 to 10.5 kg (6.48±2.05 kg). Dilatation was performed under general anesthesia with intubation and the guidance of echocardiography. During the follow-up period, all survivors had serial echocardiographic assessment to measure the transpulmonary pressure gradient (TPG) and the degree of pulmonary regurgitation. Results All operations were successful with no severe postoperative complications. Hemodynamic indexes were stable after operation with TPG lowered from from 82±27 mm Hg preoperatively to 23±12 mm Hg postoperatively (t=15.28, Plt;0.05). Only 4 patients had a TPG of more than 40 mm Hg on echocardiography before leaving the hospital. Tricuspid regurgitation was decreased significantly with 17 cases of nonregurgitation, 13 cases of light regurgitation and 2 cases of moderate regurgitation. Saturation of peripheral oxygen in all the patients increased to higher than 95%. Followup time ranged from 1 month to 4 years (16±11 months). The results of the follow-up were satisfying for all the patients. The average TPG was 17±10 mm Hg with only one above 40 mm Hg. Pulmonary valve regurgitation was found in 24 patients including 23 with light pulmonary regurgitation and 1 with moderate regurgitation. Conclusion Transthoracic balloon valvuloplasty for newborns and infants with severe and critical pulmonary valve stenosis is safe and effective.
Objective To discuss the main points of technique and the range of fusion in posterior operation of spinal stenosis associated with lumbar degenerative kyphosis (LDK). Methods The cl inical data were retrospectively analysedfrom 20 cases of spinal stenosis associated with LDK which were performed posterior operation from February 2001 to February 2008. There were 1 male and 19 females, aged 52-81 years old with an average of 64 years old. The course of disease was 6-10 years. All patients had severe low back pain. According to Frankel’s neurologic function classification, there were 18 cases of grade E and 2 cases of grade D before operation. The apex of LDK included L1 in 3 cases, L2 in 10 and L3 in 7. The operational method was decided according to different characteristics of LDK. All patients were divided into three groups. Group 1 included 6 cases of sciatica and intermittent claudication with worse physical status, the segmental decompression of spinal canal, posterior intervertebral fusion and short transpedical instrument fixation were performed. Group 2 included 8 cases whose Cobb angle of LDK was less than 20°, the segmental decompression of spinal canal, posterior intervertebral fusion and one-level or multilevel lamina osteotomy were performed, instrumentation-assisted correction was used. Group 3 included 6 cases whose Cobb angle of LDK was more than 20°, the canal decompression and one-level transvertebral wedge osteotomy were performed, instrumentation-assisted correction, intervertebral fusion and posterior-lateral fusion were used. Results Incision healedby first intention in all patients. One patient suffered from superior mesenteric artery syndrome at 6 hours after operationand healed after symptomatic management. The neurologic function was improved to grade E at 2 weeks after opeartion. All patients were followed-up 24-54 months (average 26 months). At last follow-up，the Oswestry Disabil ity Index of all patients was 30.5% ± 9.6%; showing significant difference when compared with preoperation (55.9% ± 11.8%, P lt; 0.05). The back pain scoring and leg pain scoring were 2.8 ± 1.6 and 2.4 ± 1.6, respectively according to the Numeric Rating Scale score; showing significant differences when compared with preoperation (7.5 ± 0.5 and 7.3 ± 0.7, P lt; 0.05). The Numeric Rating Scale score and Oswestry Disabil ity Index in all patients were improved obviously when compared with before operation (P lt; 0.05). During the follow-up period, there was no instrumentation failure or correction loss and the fusion rate was up to 100%. Conclusion For spinal stenosis associated with LDK patients, the most important therapic purpose is to improve cl inical symptom through reconstruction lumbar stabil ization and spinal biomechanics l ine in sagittal plane. Overall estimate of the cl inical appearance and imageology character is necessary when making decision of which segments needed to be fixation and fusion. Individual ized treatment strategy may be the best choice.
【Abstract】 Objective To discuss the main points of techniques and ranges of fusion in posterior operation ofdegenerated lumbar scol iosis compl icated spinal stenosis. Methods From February 2001 to September 2006, 23 cases with degenerated lumbar scol iosis stenosis were treated by posterior operation. There were 9 males and 14 females, with the average age of 65.3 years (ranging from 52 years to 71 years). The course of the diseases was 4 to 8 years. All patients were presented with severe low back pain. All patients were measured for Cobb angle of curves(17° to 53°), and lordosis angle of lumbar (-20° to -10° 10 cases, -40° to -20° 13 cases). Ten cases in which Cobb angle was smaller than 20° were operated by l imited segmental decompression of spinal canal, posterior intervertebral fusion and short transpedical instrument fixation. For the rest 13 cases in which Cobb angle was bigger than 20° were operated by canal decompression, longer instrument for scol iosis correction, intervertebral fusion and posterior-lateral fusion. The fixation and fusion were located at L4-S1 in 6 cases, L1-5 in 5, L2-5 in 4, L1-S1 in 5, L2-S1 in 2 and T10-S1 in 1. Results There was no patient who died from the operation. Average Cobb angle in coronal plane was 0° to 21° with the average of 15.6°. The lumbar lordosis angle was -48.0° to -18.2° with the average of -36.4°. There were 21 cases (91%) with sciatica and intermittent claudication who were clearly released. There were 20 cases (87%) whose low back pain intensely decreased. Three cases with drop-foot returned to normal activities. During the mean 15-month (6 to 54 months) follow-up for 23 cases, there was no change of corrected results and fusion rate was 100%. Conclusion For degenerated lumbar scol iosis patients, the most important purpose of the treatment is to improve cl inical symptoms through sufficient decompression of neural structures. Lumbar stabil ization reconstruction and benign spinal biomechanics l ine conduce to longterm curative effect. Overall estimate of the cl inical appearances and imageology characters is necessary when the decision, that segments are needed to be fixed and fused should be made. The strategy of the individual ized treatment may be the best choice.
Objective To investigate the operative indication and clinical efficacy of combination of external fixator and volar approach fixation in treatingdistal radius fracture. Methods From March 2000 to March 2005, 28 patients with distal radius fracture were treated with combination of external fixator and volar approach fixation. Dorsal external fixator was used to maintain wrist in functional position, combinated volar plate or Kirschner wire fixation after reduction was achieved. Bone graft was necessary if there were severe comminuted cortical bone or compress of cancellous bone. Of 28 patients, there were 21 males and 7 females, aging from 1854 years with a median age of 41 years. The locations were the left side in 4 cases and the right side in 24 cases. According to typing criterion for AO, 18 cases were classified as C2 and 10 cases as C3. One case wasaccompanied with dislocation of lunate bone. Results Among 28 patients, 24 were followed up for an average of 8.5 months. The anatomical relationship of their wristjoint were reestablished and retained. Overall good to excellent results were achieved in 87%, excellent in 16 cases, good in 5 cases and fair in 3 cases. Conclusion A combination of external fixator and volar approach fixation is an effective method of treating fractures of the distal radius，because distal radius fracture is unstable or difficult to close reduction. Volarfixation can avoid operative complication, and external fixator can obtain satisfactory reduction and function.
Objective To investigate the assessment and treatment methods for unilateral spatial agnosia as well as its influence on the functional recovery of patients after stroke, so as to comprehensively understand unilateral spatial agnosia and formulate an effective treatment plan to improve the effect of rehabilitation for stroke patients. Methods A total of 86 patients with unilateral spatial agnosia were analyzed and a pre-treatment and post-treatment comparison was done. Results Of the 86 patients, 21% suffered from unilateral spatial agnosia. The occurrence of unilateral spatial agnosia was related to the location of the stroke lesion. The treatment group witnessed significant improvement after rehabilitation training of correcting unilateral spatial agnosia (Plt;0.05). Conclusion The correct rehabilitation method is beneficial for an early improvement in a patient’s cognitive ability. This also lays a foundation for the recovery of function in their limbs.
Objective To assess the quality of the published randomized controlled trials published in Journal of Beijing University of Traditional Chinese Medicine (JBUTCM), Acta Universitatis Traditionis Medicalis Sinensis Pharmacologiaeque Shanghai (AUTMSPS), Journal of Guangdong University of Traditional Chinese Medicine (JGUTCM), and Journal of Chengdu University of Traditional Chinese Medicine (JCUTCM) from 2000 to 2005. Method Guided by the Cochrane Center hand-searching guidelines, we searched 24 volumes (111 issues) of the four journals. The data were extracted according to the principles of clinical epidemiology and consolidated standards of reporting trials (CONSORT), as well as an evaluation scale for randomized controlled trials (RCTs). The data were managed by descriptive analysis and uniformity test. Results There were 365 RCTs. The diagnostic criteria were reported in 297 trials (81.37%). The inclusion and exclusion criteria were reported in 143 trials (39.18%) and 132 trials (36.16%), perspectively, None mentioned the estimation of sample size. The randomization and allocation concealment were reported in 70 trials (19.18%) and 9 trials, perspectively. The baseline data were described in 292 trials (80.00%). Blinding was mentioned in 35 trials (9.59%).Withdrawal occurred in 20 trials (5.48%). Informed consent was acquired in 2 trials. Adverse drug reactions were described in 97 trails (26.58%). Conclusion There are deficiencies in the reporting of these RCTs, Most of the trials do not describe the randomization, only a few trials use the allocation concealment and blinded method, no description of comparability of baseline data, most of the trials do not report the inclusion and exclusion criteria, and none estimate the sample size. These problems indicate that it is necessary to improve the quality of clinical research in Chinese medicine and pharmacology.
【摘要】目的探讨重症急性胰腺炎(SAP)时胰腺组织的诱导型一氧化氮合成酶(iNOS)、内皮素（ET1） mRNA表达状态, 以及与血浆中NO、ET1浓度和肠道损伤的关系及丹参治疗的影响。方法Wistar大鼠45只随机分为3组:SAP模型组(A组),SAP丹参治疗组(B组),假手术 组(C组),进行不同治疗和观察分析。结果A组血中淀粉酶(AML)、ET1、NO、内毒素(LPS)含量、125 I白蛋白累积指数及腹水量均显著高于C组(Plt;0.01);与A组比较,B组胰腺ET1和iNOS mRNA表达较弱,血中AML、ET1、NO、LPS及腹水量显著下降(Plt;0.01),125 I白蛋白累积指数较A组也有下降,但无差异(Pgt;0.05)。结论SAP时存在肠道损伤,胰腺组织ET1、iNOS mRNA的过度表达,使血中ET1、NO浓度升高,造成肠道屏障功能受损,肠通透性增加,引起内毒素血症。丹参注射液通过减轻SAP时胰腺的病理损害程度,下调胰腺ET1和iNOS mRNA的表达,使血中ET1、NO浓度下降,对SAP及其肠道损伤有一定治疗作用。
