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 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.

ObjectiveTo investigate the effectiveness of minimally invasive plate and medial supporting cannulated screw fixation via tarsal sinus approach in treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures. Methods A clinical data of 46 patients with Sanders type Ⅱand Ⅲ calcaneal fractures met the selective criteria between March 2016 and March 2021 was retrospectively analyzed. The factures were fixed with minimally invasive plate and medial supporting cannulated screws via tarsal sinus approach in 20 cases (group A) and with minimally invasive plate in 26 cases (group B). There was no significant difference between groups in term of the gender, age, injury causes, fracture type and side, the time from injury to operation, and preoperative calcaneal length and width, B?hler angle, Gissane angle, and visual analogue scale (VAS) score (P>0.05). The operation time, intraoperative blood loss, hospital stay, and the interval between operation and full weight-bearing were recorded. The pain improvement of patients was evaluated by VAS scores before operation and at 48 hours after operation. The ankle joint function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score at 3 and 12 months after operation. Besides, the calcaneal length and width, B?hler angle, and Gissane angle were measured by X-ray films before and after operation. Furthermore, the difference (loss value) between 3, 12 months and 1 day after operation was calculated. Moreover, the fracture healing and healing time was observed. ResultsAll operations of two groups were successfully completed. The incisions healed by first intention, and no vascular/nerve injury or incision infection occurred. The operation time of group A was significantly longer than that of group B (P<0.05). There was no significant difference in the intraoperative blood loss, hospital stay, and the interval between operation and full weight-bearing (P>0.05). All patients were followed up 12-36 months (mean, 14.8 months). The VAS scores at 48 hours after operation were significantly lower than those before operation in the two groups (P<0.05); there was no significant difference in the difference of pre- and post-operative VAS score between groups (P>0.05). The AOFAS scores at 12 months after operation were significantly higher than those at 3 months after operation in the two groups (P<0.05); and there was no significant difference between groups at 3 and 12 months (P>0.05). X-ray films showed that the fractures of the two groups healed and there was no significant difference in healing time (P>0.05). There was no significant difference in calcaneal length and width and Gissane angle between groups at each time point (P>0.05), but there was significant difference in B?hler angle between groups at 12 months (P<0.05). The imaging indexes of the two groups significantly improved at each time point after operation when compared with those before operation (P<0.05). There was no significant difference between different time points after operation (P>0.05) in the imaging indexes of group A. There were significant differences in the calcaneal length, calcaneal width, and Gissane angle of group B between 12 months and 1 day, 3 months after operation (P<0.05), and there was no significant difference between 1 day and 3 months after operation (P>0.05). The differences in B?hler angle of group B between different time points after operation were significant (P<0.05). There was no significant difference between groups in the loss of all imaging indexes at 3 months after operation (P>0.05). The losses of calcaneal width, B?hler angle, and Gissane angle in group A at 12 months after operation were significantly smaller than those in group B (P<0.05), and there was no significant difference in the loss of calcaneus length between groups (P>0.05). ConclusionCompared with only minimally invasive plate fixation, the combination of minimally invasive plate and medial supporting cannulated screw fixation via tarsal sinus approach for Sanders type Ⅱ and Ⅲ calcaneal fractures has the advantages of less trauma, less incision complications, reliable fracture reduction and fixation, and good long-term stability.
【摘要】目的探討重癥急性胰腺炎(SAP)時胰腺組織的誘導型一氧化氮合成酶(iNOS)、內皮素（ET1） mRNA表達狀態, 以及與血漿中NO、ET1濃度和腸道損傷的關系及丹參治療的影響。方法Wistar大鼠45只隨機分為3組:SAP模型組(A組),SAP丹參治療組(B組),假手術 組(C組),進行不同治療和觀察分析。結果A組血中淀粉酶(AML)、ET1、NO、內毒素(LPS)含量、125 I白蛋白累積指數及腹水量均顯著高于C組(Plt;0.01);與A組比較,B組胰腺ET1和iNOS mRNA表達較弱,血中AML、ET1、NO、LPS及腹水量顯著下降(Plt;0.01),125 I白蛋白累積指數較A組也有下降,但無差異(Pgt;0.05)。結論SAP時存在腸道損傷,胰腺組織ET1、iNOS mRNA的過度表達,使血中ET1、NO濃度升高,造成腸道屏障功能受損,腸通透性增加,引起內毒素血癥。丹參注射液通過減輕SAP時胰腺的病理損害程度,下調胰腺ET1和iNOS mRNA的表達,使血中ET1、NO濃度下降,對SAP及其腸道損傷有一定治療作用。
ObjectiveTo evaluate the effectiveness of a new type of sutured titanium wire combined with titanium nail internal fixation in correction of serious old medial canthus deformity.MethodsBetween March 2012 and June 2015, 18 patients with unilateral serious old medial canthus deformity were treated. There were 14 males and 4 females. The patient’s age ranged from 23 to 62 years (mean, 42 years). The causes of deformity included accident injury in 10 cases, boxing injury in 4 cases, sharp device scratching in 3 cases, and animal bite in 1 case. All patients had been treated with suture or steel wire fixation in other hospitals to correct the medial canthus deformity and the deformity recurred. The interval between this operation and the first operation was 6 months to 2 years (mean, 16 months). The nasal root or medial canthus skin scar incision was used as the operative approach, and the adhesion of the medial canthus ligament to the adjacent tissues was fully loosened, then the tail end of the new type sutured titanium wire was fixed to the residual end of the medial canthus ligament. After passing through the scar tissue, the needle end of wire was fixed on the titanium nail in the bone wall of anterior lacrimal crest. The position and shape of the medial canthus angle was determined by adjusting the tightness of titanium wire.ResultsAll incisions healed by first intention. All patients were followed up 6-12 months (mean, 10 months). In 16 cases, the medial canthus deformity was obviously corrected, and the appearances of bilateral eyes were basically symmetrical, without exposure of titanium nail and titanium wire. The medial canthus was retreated at 2 mm after 6 months in 2 cases, who were satisfied with their appearance without reoperation.ConclusionApplication of the new type of suture titanium wire combined with titanium nail in the correction of serious old medial canthus deformity can achieve good effectiveness with the low recurrence rate.
ObjectiveTo explore the clinical characteristics and long term mortality of patients with eosinophilic and neutrophilic chronic obstructive pulmonary disease (COPD) exacerbations requiring hospital admission.MethodsA retrospective review of the clinical data and long-term follow up was performed for 510 patients with first diagnosis of acute exacerbation of COPD (AECOPD) requiring hospital admission between January 2015 and December 2016. The follow-up was completed in January 1, 2020. These patients were divided into three groups according to routine blood test: an eosinophilic exacerbation group, with peripheral blood eosinophils >2%; a neutrophilic exacerbation group, with peripheral blood neutrophils >65% or leukocytes >11×109/L; a paucigranulocytic exacerbation group, any case did not belong to the above two groups. The differences of clinical characteristics were compared among three groups. Cox regression model was used for analysis of independent risk factors of all-cause mortality of AECOPD patients.ResultsA total of 510 AECOPD patients were enrolled (180 eosinophilic, 273 neutrophilic and 57 paucigranulocytic, respectively). Compared with the neutrophilic exacerbation group, the eosinophilic exacerbation group had shorter time since onset of symptoms, the lower proportion of comorbid heart failure, the lower proportion of mechanical ventilation, dual antibiotics and systematic corticosteroid treatment, the shorter length of hospitalization and lower hospital mortality (all P<0.05). The average follow-up duration was 41 months for 485 AECOPD patients who completed long term follow-up. Compared with the eosinophilic exacerbation group, the neutrophilic exacerbation group was associated with a higher long-term mortality of AECOPD (HR=1.691, 95%CI 1.205 - 2.373, P=0.002).ConclusionCOPD patients with neutrophilic exacerbations have more serious clinical features and higher mortality than those with eosinophilic exacerbations.
ObjectiveTo systematically review the efficacy of antibiotics on the outcomes of patients with non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors. MethodsPubMed, EMbase, Web of Science, The Cochrane Library, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect cohort studies on efficacy of antibiotics on the outcomes of patients with NSCLC treated with immune checkpoint inhibitors from inception to August 1st, 2021. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 software. ResultsA total of 27 cohort studies involving 7 087 patients were included. The results of meta-analysis showed that antibiotic use was associated with poor overall survival (OS) (HR=2.04, 95%CI 1.68 to 2.49, P<0.000 01) and progression free survival (PFS) (HR=1.63, 95%CI 1.35 to 1.99, P<0.000 01). ConclusionCurrent evidence shows that antibiotic use is associated with poor OS and PFS. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.
【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 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.
