Objective To analyze and compare the clinical application values of procalcitonin (PCT),leukocyte count (WBC) and C-reactive protein(CRP) in elder patients with infection.Methods In patients(age≥ 65 yrs,axillary temperature ＞38.0℃)with infection or suspected infection,PCT,WBC,CRP and other bacteriological examination were performed.The electronic medical records from the HIS system of our hospital were analyzed retrospectively in combination with medical history.Results Of the enrolled 219 patients,65 ones were in control group,48 ones SIRS,51 ones sepsis and 55 ones MODS.There was a positive correlation between the level of serum PCT and the infection degree.The Spearman correlation coefficient was 0.706 (95％CI:0.616-0.797,P=0.000).Based on the highest Youden index (sensitivity+specificity-1),the best cutoff point of diagnosis for PCT was ＞0.341 μg/L (sensitivity 84.5％,specificity 55.8％),a analysis of receiver operating characteristic(ROC) curve about PCT,WBC and CRP was carried.Area under the curve (AUC) of PCT to controlled infection was 0.916 (95％CI:0.864-0.967,P=0.000).Based on the highest Youden index (sensitivity+ specificity-1),the judging threshold of PCT to infection controlled or not was 0.73 μg/L (sensitivity 84.6％,specificity 88.0％).PCT level after treatment ＞0.73 μg/L showed the uncontrolled infection,＜ 0.73 μg/L controlled.Conclusions PCT has a higher specificity for elder patients with infection.The variation of PCT level can guide the application of antibiotics,avoid abuse and decrease the occurrence of drug-resistant bacteria.

OBJECTIVETo explore the effective techniques for correction of lacrimal groove and palpebromalar groove deformity in the middle-aged and old people.

METHODThe lacrimal groove and palpebromalar groove deformity was corrected by the techniques of transcutaneous orbital fat releasing and pedicle orbital fat flap filling. From 1996 to 2011, 426 patients, aged from 35 to 72 (average, 48), were treated by the techniques. Among them, 54 patients had underwent the surgical treatment before this operation. 362 patients were followed up for 3-24 months.

RESULTSCompletely correction was achieved in 283 patients, obvious improvement in 79 patients. The result was not satisfied in 2 patients with severe deformity who had surgical treatment before.

CONCLUSIONThe lacrimal groove and palpebromalar groove deformity can be effectively corrected by transcutaneous orbital fat releasing and pedicle orbital fat flap in the middle-aged and old people.

BACKGROUND: Spontaneous recovery of severe alopecia areata is rare and the condition is difficult to treat. OBJECTIVE: The aim of this study is to investigate and compare the effects and safety of steroid pulse therapy between oral and intravenous administrations between 1999 and 2010 at the Department of Dermatology, National Cheng Kung University Hospital. METHODS: Data were retrospectively retrieved. A satisfactory response was defined as more than 75% hair regrowth in the balding area. RESULTS: A total of 85 patients with more than 50% hair loss were identified and treated, with an overall satisfactory response rate of 51.8%. The mean follow-up time was 37.6 months, with a relapse rate of 22.7%. Patients with alopecia areata (hereafter, AA) of recent onset within one year showed higher response rates (p<0.001) and lower relapse rates compared to patients with AA persisting for more than 1 year. Further, even in patients with alopecia totalis, alopecia universalis or ophiasis type, early treatment resulted in a satisfactory response rate of 47% among the treated patients. In general, oral therapy was as effective and well-tolerated as intravenous therapy. CONCLUSION: The response rate is determined by disease severity and time of intervention, not by the administration form of steroid pulse therapy. Oral steroid pulse therapy can be considered as the first-line treatment for patients with severe AA of recent onset within one year.

Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique, has been increasingly used to treat bipolar depression. Researchers recently noticed the risk of tDCS-emergent mania/hypomania in depressed patients and started to evaluate this risk by launching a meta-analysis. Here we present a female with bipolar II depression who rapidly developed hypomanic switching during bifrontal tDCS.

Mutations in the synaptic nuclear envelope protein 1 (SYNE1) gene are associated with substantial clinical heterogeneity. Here, we report the first case of SYNE1 ataxia in Taiwan due to two novel truncating mutations. Our patient, a 53-year-old female, exhibited pure cerebellar ataxia with c.1922del in exon 18 and c. C3883T mutations in exon 31. Previous studies have indicated that the prevalence of SYNE1 ataxia among East Asian populations is low. In this study, we identified 27 cases of SYNE1 ataxia from 22 families in East Asia. Of the 28 patients recruited in this study (including our patient), 10 exhibited pure cerebellar ataxia, and 18 exhibited ataxia plus syndromes. We could not find an exact correlation between genotypes and phenotypes. Additionally, we established a precise molecular diagnosis in our patient’s family and extended the findings on the ethnic, phenotypic, and genotypic diversity of the SYNE1 mutational spectrum.

Tubulin beta 4A class IVa (TUBB4A) spectrum disorders include autosomal dominant dystonia type 4 or hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC syndrome). However, in rare cases, only mild hypomyelination in the cortex with no basal ganglia atrophy may be observed. We report a case of a family with TUBB4A mutation and complicated hereditary spasticity paraplegia (HSP). We performed quadro whole-exome sequencing (WES) on the family to identify the causative gene of progressive spastic paraparesis with isolated hypomyelination leukodystrophy. We identified a novel TUBB4A p.F341L mutation, which was present in all three affected patients but absent in the unaffected father. The affected patients presented with adult-onset TUBB4A disorder, predominant spastic paraparesis with/without ataxia, and brain hypomyelination with no cognitive impairment or extrapyramidal symptoms. In the literature, HSP is considered a TUBB4A spectrum disorder.

OBJECTIVEObese children and adolescents are often complicated with the abnormalities of lipid and glucose metabolism, which are often associated with adulthood hypertension, diabetes and cardiovascular disease. In this study, the blood lipids, blood pressure and carotid arterial intima-media thickness (IMT) in obese children and adolescents were measured to investigate the relationship between the dyslipidemia and early vascular lesions.

METHODA total of 580 obese children and adolescents aged from 7 to 17 years of age were enrolled from 3 hospitals from Jan. 2008 to Sept. 2009. They were divided into 2 groups according to their blood lipoid levels. Ortholiposis group included 100 males and 52 females with a mean age of 10.47 years and a mean body mass index (BMI) of 28.28 kg/m(2). Dyslipidemia group included 305 males and 123 females with a mean age of 10.83 years and a mean BMI of 27.60 kg/m(2). Physical examination, and measurement of blood lipid, glucose and liver enzyme were taken. Carotid IMT was measured for 285 subjects.

RESULT(1) Hypertension was found in 12.5% (19/152) and 20.1% (86/428) patients in ortholiposis and dyslipidemia groups, respectively, with a significant difference (χ(2) = 4.362, P = 0.037). The OR was 1.760 with 95% confidence interval of 1.030 - 3.008. Higher prevalence of hypertension was found in patients with dyslipidemia. (2) The left, right and mean common carotid IMTs of dyslipidemia group were higher than those of ortholiposis group without significant difference (all P > 0.05). The left, right and mean internal carotid IMTs in dyslipidemia group were (0.66 ± 0.15) mm, (0.65 ± 0.15) mm and (0.65 ± 0.15) mm, respectively while these in ortholiposis group were (0.62 ± 0.13) mm, (0.60 ± 0.13) mm and (0.61 ± 0.12) mm, respectively (P < 0.05 for all). (3) Bivariate correlation analysis showed that systolic blood pressure was positively correlated with age, BMI, BMI Z score, waist circumference, hip circumference, uric acid, alanine transaminase, triglyceride, fasting insulin and insulin resistance index (P < 0.05 for all). Moreover, mean carotid and internal carotid IMTs were positively correlated with age, BMI, waist circumference, hip circumference, and triglyceride (all P < 0.05). Multiple linear regression analysis showed that hip circumference and insulin resistance index were independent determinants of systolic pressure. Waist circumference was independent determinant of mean common and internal carotid IMT and triglyceride was independent determinants of mean internal carotid IMT.

CONCLUSION(1) Vascular lesions, including hypertension and thicker tunica intima are common in obese children and adolescents. (2) Vascular lesions are closely related with dyslipidemia, and waist circumference and hypertriglyceridemia are the risk factors.

OBJECTIVE Tissue plasminogen activator (tPA) is the only approved pharmaco-logical therapy for acute brain ischaemia;however,a major limitation of tPA is the haemorrhagic trans-formation that follows tPA treatment. Here, we determined whether nicotinamide mononucleotide (NMN), a key intermediate of nicotinamide adenine dinucleotide biosynthesis, affects tPA-induced haemorrhagic transformation. METHODS Middle cerebral artery occlusion (MCAO) was achieved in CD1 mice by introducing a filament to the left MCA for 5 h.When the filament was removed for reperfusion, tPA was infused via the tail vein.A single dose of NMN was injected i.p.(300 mg·kg-1).Mice were killed at 24 h post ischaemia, and their brains were evaluated for brain infarction, oedema, haemoglobin content, apoptosis, neuroinflammation, blood-brain barrier (BBB) permeability, the expression of tight junction proteins(TJPs)and the activity/expression of MMPs. RESULTS In the mice infused with tPA at 5 h post ischaemia, there were significant increases in mortality, brain infarction, brain oedema, brain haemoglobin level, neural apoptosis, Iba-1 staining (microglia activation) and myeloperoxidase staining (neutrophil infiltration). All these tPA-induced alterations were significantly prevented by NMN administration. Mechanistically, the delayed tPA treatment increased BBB permeability by down-regulating TJPs, including claudin-1, occludin and zonula occludens-1,and enhancing the activities and protein expression of MMP9 and MMP2. Similarly, NMN administration partly blocked these tPA-induced molecular changes. CONCLUSION Our results demonstrate that NMN ameliorates tPA-induced haemorrhagic transformation in brain ischaemia by maintaining the integrity of the BBB.

Triple-negative breast cancer (TNBC) remains difficult to treat and urgently needs new therapeutic options. Nintedanib, a multikinase inhibitor, has exhibited efficacy in early clinical trials for HER2-negative breast cancer. In this study, we examined a new molecular mechanism of nintedanib in TNBC. The results demonstrated that nintedanib enhanced TNBC cell apoptosis, which was accompanied by a reduction of p-STAT3 and its downstream proteins. STAT3 overexpression suppressed nintedanib-mediated apoptosis and further increased the activity of purified SHP-1 protein. Moreover, treatment with either a specific inhibitor of SHP-1 or SHP-1-targeted siRNA reduced the apoptotic effects of nintedanib, which validates the role of SHP-1 in nintedanib-mediated apoptosis. Furthermore, nintedanib-induced apoptosis was attenuated in TNBC cells expressing SHP-1 mutants with constantly open conformations, suggesting that the autoinhibitory mechanism of SHP-1 attenuated the effects of nintedanib. Importantly, nintedanib significantly inhibited tumor growth via the SHP-1/p-STAT3 pathway. Clinically, SHP-1 levels were downregulated, whereas p-STAT3 was upregulated in tumor tissues, and SHP-1 transcripts were associated with improved disease-free survival in TNBC patients. Our findings revealed that nintedanib induces TNBC apoptosis by acting as a SHP-1 agonist, suggesting that targeting STAT3 by enhancing SHP-1 expression could be a viable therapeutic strategy against TNBC.
