BACKGROUND AND PURPOSE: Recombinant tissue plasminogen activator (rtPA) is one of the proven therapies that improve the outcome of patients with acute ischemic stroke (AIS). In 2009, the Ministry of Health and Welfare, Executive Yuan, Republic of China, launched the project “Hospital Emergent Capability Accreditation by Level-Stroke (HECAL-Stroke)” to improve AIS treatment in Taiwan. The current study was performed to determine whether the project launched by the government was effective in promoting rtPA therapy among AIS patients. METHODS: All participating hospitals were verified and designated as “heavy duty (HD),”“moderate duty (MoD),” or “medium duty (MeD)” according to the stroke center criteria. Four annual indices (rates of treatment, protocol adherence, in-time treatment, and complications) were recorded from 2009 to 2014 as outcome measures. The data were analyzed using the χ² test for significance. RESULTS: The number of certified hospitals progressively increased from 74 to 112 during the 6-year period and finally consisted of 33 HD, 9 MoD and 70 MeD hospitals in 2014. The annual intravenous rtPA treatment rate increased significantly from 3.0% in 2009 to 4.5% in 2014. The protocol adherence rates were 95.7% in the HD group, 92.4% in the MoD group and 72.8% in the MeD group. The annual in-time treatment rate significantly improved from 26.0% in 2009 to 60.1% in 2014. The overall symptomatic intracranial hemorrhagic rate after rtPA treatment was 8.6%. CONCLUSIONS: Initiation of the HECAL-Stroke project by the government significantly improved rtPA treatment in Taiwan.

OBJECTIVETo evaluate the feasibility and the therapeutic effect of orthognathic surgical procedures combined distraction osteogenesis and scapular flap for correction of progressive hemifacial atrophy.

METHODS5 cases with progressive hemifacial atrophy were treated. 1 mild case was treated with microsurgical de-epithelia scapular flap (MDSF) and genioplasty in one stage. The 2 moderate cases were treated with Le Fort 1 osteotomy following by sagittal split ramus osteotomy and genioplasty at the first stage. 3 - 6 months later, the MDSFs were used for augmentation. 2 sever cases were treated with bimaxillary distraction osteogenesis on the affected side. 3 - 4 months later, the distraction devices were removed and MDSFs were transplanted.

RESULTSThe facial asymmetry was obviously improved. The orthognathic procedures and distraction osteogenesis achieved good therapeutic effect. All the MDSFs were survived.

CONCLUSIONSThe progressive hemifacial atrophy can result in very severe deformity when it occurs in very young age. The combined deformity of bone and soft tissue can be effectively corrected by orthognathic procedures combined with distraction osteogenesis and scapular flap transplantation.

Objective: To observe the clinical efficacy of 'Tong Du Yun Pi' (Governor Vessel-unblocking and spleen-promoting) manipulation in treating infantile diarrhea in autumn. Methods: Eighty-four kids were divided into a control group and an observation group using the random number table method, with 42 cases in each group. The control group was intervened by oral administration of montmorillonite powder, and the observation group was given additional 'Tong Du Yun Pi' pediatric massage (tuina) treatment. After treatment, the traditional Chinese medicine (TCM) symptoms scores, symptom improvement time, clinical efficacy and immune function indicators were compared between the two groups. Results: After treatment, the total effective rate was 95.2％ in the observation group versus 76.2％ in the control group, and the between-group difference was statistically significant (P<0.05); each item score in TCM symptoms was notably lower in the observation group than in the control group (all P<0.05); among the effective cases, the times to restore normal defecation, relieve abdominal bloating, arrest vomiting, and bring down the fever were markedly shorter in the observation group than in the control group, and the between-group differences were statistically significant (all P<0.05); the levels of immunoglobulin (Ig) G, IgM, CD4+ and CD4+/CD8+ were significantly higher and CD8+ was significantly lower in the observation group than in the control group (all P<0.05). Conclusion: In the treatment of infantile diarrhea in autumn, based on oral administration of montmorillonite powder, 'Tong Du Yun Pi' manipulation can notably improve diarrheal symptoms, shorten disease duration, and strengthen the immunity of kids, producing more significant efficacy than oral administration of montmorillonite powder.

OBJECTIVETo explore the treatment of cervical tracheoesophageal fistula (TEF) with complicated or remnant laryngotracheal stenosis (LTS) and anterior neck defect (AND).

METHODSFrom 1980 to 2007, 14 patients were diagnosed as TEF. Among them, 9 patients had complicated or remnant LTS, 3 patients had complicated AND, and 2 patients had TEF which were induced by Nickel-Titanium alloy mesh stent for treating benign esophageal stricture. All these patients were retrospectively studied in Tangdu Hospital. Treatment consisted of conservative therapy of TEF, staged surgical repair of TEF and laryngotracheal reconstruction according to the dimension (small or large) of TEF and complications.

RESULTSFour patients with small TEF (2 - 3 mm length) complicated LTS underwent laryngotracheal reconstruction stented with silicone T tube and TEF was adopted conservative treatment. The TEF and LTS were healed. Six patients with larger TEF (10 - 25 mm length) were repaired by staged surgical repair of TEF and laryngotracheal reconstruction. Among them, 3 cases had complicated LTS and AND, 2 cases had recent LTS and 1 case had TEF without complication. Two patients had TEF and LTS, whose TEF healed before laryngotracheal reconstruction, the remnant LTS were reconstructed and healed. During the follow-up ranged from one to ten years, 12 patients were successfully treated without complications. One patient with TEF and LTS was treated only LTS because of a segment of esophagus was closed and treated with esophagogastrostomy in the department of thoracic surgery after LTS was successfully reconstructed and cured. One patient died of bleeding and asphyxia induced by the Nickel-Titanium alloy stent because of the stent had not been taken out.

CONCLUSIONThe small cervical TEF complicated or remnant LTS can be treated by laryngotracheal reconstruction and conservative treatment of TEF at the same time. A larger TEF complicated LTS should be treated by staged repair of TEF and LTS.

OBJECTIVETo determine whether early catheterization laboratory activation would reduce median door-to-balloon time in patients with ST elevation myocardial infarction (STEMI).

METHODSConsecutive patients with STEMI underwent primary percutaneous coronary intervention (PCI) from January 2006 to December 2008 in Beijing Anzhen Hospital were analyzed. Patients were divided into three groups. Group A included patients without prehospital ECG (n = 168), group B included patients with prehospital ECG (n = 224) and group C included patients with prehospital ECG and early telephonic notification to activate catheterization laboratory (n = 114). Primary end point was door-to-balloon time, secondary end points included peak Troponin I elevation, left ventricular ejection fraction, length of hospital stay, hospital mortality and 30 days follow-up mortality.

RESULTSBaseline characteristics were similar among groups. Door-to-balloon time and door-to-catheter laboratory time (110 minutes, 94 minutes and 85 minutes, respectively, all P < 0.01; 91 minutes, 74 minutes and 64 minutes, respectively, all P < 0.01) were significantly shorter in group B and C than those in group A. The percentage of patients with door-to-balloon time less than 90 minutes increased significantly from 32% in group A to 43% in group B and 59% in group C (P < 0.01).

CONCLUSIONEarly activation of catheterization laboratory by prehospital ECG and telephonic notification could markedly reduce door-to-balloon time in patients with STEMI.

OBJECTIVETo investigate the value of virtual surgery in hepatic artery reconstruction in liver recipients with type II hepatic artery variation.

METHODSA patient with cholangiocellular carcinoma and a healthy individual were scanned using 64-slice spiral CT, and image segmentation and three-dimensional (3D) reconstruction were performed using an image processing system. The 3D models in STL format were then imported to the FreeForm Modeling System for smoothing and refinement. Hepatic artery reconstruction was performed in simulated liver transplantation using the virtual surgery system with force feedback (PHANTOM).

RESULTSThe reconstructed model contained the liver, hepatic arteries, biliary system, and bile duct tumor emboli and displayed the entire branching of the hepatic artery with type II variation. Using the virtual surgery system, arterial reconstruction was performed by anastomosing the donor celiac trunk and the recipient abdominal aorta with the virtual scalpel and needle.

CONCLUSIONThe reconstructed model allows clearer views of the 3D structures of the arteries in the liver and helps in preoperative preparations and surgical planning of artery reconstruction during liver transplantation. This approach may also help reduce the surgical risks and potential complications.

OBJECTIVETo explore the efficacy of anterior percutaneous screw fixation in the treatment of odontoid process fractures in aged people.

METHODSFrom February 2001 to April 2009, 15 elderly patients with odontoid fracture were treated with anterior percutaneous screw fixation,including 13 males and 2 females; the average age was 69.3 years (ranged, 60 to 86 years). According to Anderson classification, there were 10 patients with type II fractures (type II A in 7 cases, type II B in 3 cases, based on Eysel and Roosen classification), 4 patients with shallow type III fractures, 1 patient with deep type III fractures. Thirteen patients were fresh fractures, 2 patients were obsolete fractures. All patients had varying degrees of neck or shoulder pain, and limit activity of neck. There were 4 patients with neural symptoms including 2 grade D and 2 grade C according to Frankel classification. All the patients were followed up and were assessed by radiology. Clinical examination included neck activity, neurological function and the degree of neck pain. Radiology examinations including anteroposterior, lateral, open mouth position and flexion-extension radiographs of cervical vertebra were performed.

RESULTSAfter surgery, all patients were followed up,and the duration ranged from 6 to 60 months (averaged 31.3 months). Two patients died of other diseases during the follow-up period (18 and 22 months after surgery respectively). All patients got satisfactory results, and all screws were in good position. As the screw was too long, esophagus was compressed by screw tail in one case. One case showed fibrous union, 12 cases had achieved solid bony union, 2 cases showed nonunion without clinical symptoms. The rotation of neck in 3 cases was mildly limited,the neck function of the remaining patients were normal. Four patients with symptoms nerve injuries improved after operation (Frankel E in 3 cases, Frankel D in 1 case). The symptom of neck pain had a significant improvement after surgery (P < 0.001). The VAS score decreased from preoperative (6.07 +/- 1.44) (4 to 8 scores),to postoperative (1.13 +/- 0.92) (0 to 3 scores). And there were no severe postoperative complications.

CONCLUSIONThe anterior percutaneous screw fixation is less traumatic than conventional approaches for aged people in dealing with odontoid process fractures. Most patients will achieve satisfactory clinical results, as long as the general conditions of them are comprehensively assess. However, this procedure should not be used in patients with comminuted odontoid fractures or severe osteoporosis.

OBJECTIVETo study the effects of intrahippocampal injection of cellular prion protein (PrP) antibody on cognitive deficits of APPswe/PSEN1 transgenic mice.

METHODSEight-month-old male APPswe/PSEN1 transgenic mice were subjected to bilateral intrahippocampal injection of a single dose (2 µL) of anti-PrP monoclonal antibody (EP1802Y) or PBS, with wild-type C57Bl/6J mice serving as the control group. After two months, the mice were tested for cognitive behaviors using open filed (OF) test, Morris water maze (MWM) test, fear conditioning (FC) test, and novel object recognition (NOR) test, and immunohistochemistry was used to examine the changes in hippocampal expression of Aβ.

RESULTSThe EP1802Y-treated and PBS-treated mice showed no significantly differences in the performance in OF test in terms of central activity time or total distance of activity (P>0.05), nor in NOR test in terms of novel object recognition index (P>0.05). In MWM test, the EP1802Y-treated and PBS-treated mice showed significantly reduced crossings of the hidden platform as compared with the wild-type mice (P<0.05), but EP1802Y-treated mice had a significantly shorter swimming distance to find the platform than PBS-treated mice (P<0.05). No significant differences were found in the results of FC test among the 3 groups. Immunohistochemistry revealed a significantly reduced expression of Aβ in the hippocampus of EP1802Y-treated mice.

CONCLUSIONIntrahippocampal injection of PrP antibody can improve cognitive deficits of APPswe/PSEN1 transgenic mice, which sheds light on a novel therapeutic approach for Alzheimer's disease that targets PrP to lower the toxicity of Aβ oligomer.

Background/Aims: Chronic hepatitis C (CHC) patients who failed antiviral therapy are at increased risk for hepatocellular carcinoma (HCC). This study assessed the potential role of metformin and statins, medications for diabetes mellitus (DM) and hyperlipidemia (HLP), in reducing HCC risk among these patients. Methods: We included CHC patients from the T-COACH study who failed antiviral therapy. We tracked the onset of HCC 1.5 years post-therapy by linking to Taiwan’s cancer registry data from 2003 to 2019. We accounted for death and liver transplantation as competing risks and employed Gray’s cumulative incidence and Cox subdistribution hazards models to analyze HCC development. Results: Out of 2,779 patients, 480 (17.3%) developed HCC post-therapy. DM patients not using metformin had a 51% increased risk of HCC compared to non-DM patients, while HLP patients on statins had a 50% reduced risk compared to those without HLP. The 5-year HCC incidence was significantly higher for metformin non-users (16.5%) versus non-DM patients (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Statin use in HLP patients correlated with a lower HCC risk (3.8%) compared to non-HLP patients (12.5%; aSHR=0.50; P<0.001). Notably, the increased HCC risk associated with non-use of metformin was primarily seen in non-cirrhotic patients, whereas statins decreased HCC risk in both cirrhotic and non-cirrhotic patients. Conclusions Metformin and statins may have a chemopreventive effect against HCC in CHC patients who failed antiviral therapy. These results support the need for personalized preventive strategies in managing HCC risk.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is an increasingly common liver disease worldwide. MAFLD is diagnosed based on the presence of steatosis on images, histological findings, or serum marker levels as well as the presence of at least one of the three metabolic features: overweight/obesity, type 2 diabetes mellitus, and metabolic risk factors. MAFLD is not only a liver disease but also a factor contributing to or related to cardiovascular diseases (CVD), which is the major etiology responsible for morbidity and mortality in patients with MAFLD. Hence, understanding the association between MAFLD and CVD, surveillance and risk stratification of MAFLD in patients with CVD, and assessment of the current status of MAFLD management are urgent requirements for both hepatologists and cardiologists. This Taiwan position statement reviews the literature and provides suggestions regarding the epidemiology, etiology, risk factors, risk stratification, nonpharmacological interventions, and potential drug treatments of MAFLD, focusing on its association with CVD.
