Variety of biomarkers that are related to the Alzheimer's disease and its diagnosis and progress have been found. However, research lacks in predicting the reaction of the treatment. In addition, there is no definite treatment reaction to the disease but rather it is varied. The purpose of this review article is to study the research of the biomarkers that are able to predict the treatment reaction. There was a research that illustrated a relationship between plasma amyloid ${\beta}$ peptide, cerebrospinal fluid tau, neuroanatomical biomarkers and acetylcholinesterase inhibitors. Polymorphisms in genes of the cholinergic markers AChE, BuChE, ChAT and PON-1 were found to be associated with better clinical response to acetylcholinesterase inhibitors. Many pharmacogenetic studies have been conducted to evaluate the impact of the lipoprotein apolipoprotein E (APOE) genotype on treatment response to acetylcholinesterase inhibitor. However, there is no significant influence of the APOE genotypes on treatment response. Further research is needed to find other predictors of treatment with acetylcholinesterase inhibitors in patients with Alzheimer's disease.

Immunoglobulin G4-related disease (IgG4RD) is a chronic inflammatory condition characterized by tissue infiltration with lymphocytes and IgG4-secreting plasma cells, as well as varying degrees of fibrosis. We report a case of a 70-year-old man with a rapid-growing cervical mass for several months. Computed tomography and positron emission tomography showed a huge, ill-defined mass involving left thyroid lobe and encasing the common carotid artery, which was clinically and radiologically suspicious for anaplastic thyroid carcinoma. Ultrasonography-guided core needle biopsy was performed and histopathology examination revealed to be consistent with IgG4RD, and the IgG4/IgG ratio was 0.6. After oral corticosteroid was administered, the mass was dramatically resolved. Because IgG4RD often presents as a single localized and infiltrated mass lesion, it can be confused and misdiagnosed as a malignancy. Thus, clinicians should consider IgG4RD as a differential diagnosis in a rapid-growing neck mass to prevent unnecessary and excessive treatments.

Rhabdomyolysis is a syndrome caused by injury to skeletal muscles and involves leakage of large quantities of potentially toxic intracellular contents into the plasma. It is known that rhabdomyolysis results in peripheral nerve injury, however, reports of bilateral sciatic neuropathy following rhabdomyolysis are rare. We report a case involving a 42-year-old female patient with no past medical history, who presented with sudden bilateral calf pain, redness, and burning sensation with weakness of both lower extremities after sleeping on an electric heating pad following alcohol drinking. Lower extremity magnetic resonance angiography (MRA) revealed multifocal edema with enhancement of bilateral lower extremity muscles. Clinical and electrodiagnostic tests were consistent with the diagnosis of bilateral sciatic neuropathy following rhabdomyolysis. This is a rare case of bilateral sciatic neuropathy following rhabdomyolysis.

Objectives The purpose of this research is to comprehensively analyze about Jowiseungcheong-tang (Diàowèishēngqīng-tāng). This herbal medicine is widely used to treat obesity and metabolic disease. Methods We used 3 search terms, 'Jowiseungcheong-tang', 'Jowiseungcheong-tang plus obesity' and 'Jowiseungcheong-tang plus metabolic disease' in Korean word via 5 domestic databases. Therefore, 8 laboratory experiments and 4 clinical researches were chosen. Results Jowiseungcheong-tang (Diàowèishēngqīng-tāng) was identified as a herbal medicine for obesity and related metabolic disease. In plasma level of lipid, leptin, inflammatory material were decreased in laboratory experiments. Weight loss and symptom relief were reported in clinical research. Conclusions Definite information about laboratory experiment was showed, specifically suitable index and numerical value. In clinical research, although Jowiseungcheong-tang (Diàowèishēngqīng-tāng) is widely used for obesity and metabolic disease, the number of reported thesis and patient were pretty a few. Also, diagnosis methods were also scanty. Multi-institutional clinical trial should be progressed.

Long-chain fatty acid oxidation disorders (LC-FAOD) are an autosomal recessive inherited rare disease group that result in an acute metabolic crisis and chronic energy deficiency owing to the deficiency in an enzyme that converts long-chain fatty acids into energy. LC-FAOD includes carnitine palmitoyltransferase type 1 (CPT1), carnitine-acylcarnitine translocase (CACT), carnitine palmitoyltransferase type 2 (CPT2), very long-chain acyl-CoA dehydrogenase (VLCAD), long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD), and trifunctional protein (TFP) deficiencies. Common symptoms of LC-FAOD are hypoketotic hypoglycemia, cardiomyopathy, and myopathy. Depending on symptom onset, the disease can be divided as neonatal period, late infancy and early childhood, adolescence, or adult onset, but symptoms can appear at any time. The neonatal screening test (NBS) can be used to identify the characteristic plasma acylcarnitine profiles for each disease and confirmed by deficient enzyme analysis or molecular testing. Before introduction of NBS, the mortality rate of LC-FAOD was very high. With NBS implementation as routine neonatal care, the mortality rate was dramatically decreased, but severe symptoms such as rhabdomyolysis recur frequently and affect the quality of life. Triheptanoin (Dojolvi^®), the first drug for pediatric and adult patients with molecularly confirmed LC-FAOD, has recently been approved by the US Food and Drug Administration in 2020. In this review, the diagnosis of LC-FAOD and treatment including triheptanoin are summarized.

Acute myocardial infarction (AMI) is a multifaceted syndrome influenced by the functions of various extrinsic and intrinsic pathways and pathological processes, which can be detected in circulation using biomarkers. In this study, we investigated the secretome protein profile of induced-hypertrophy cardiomyocytes to identify next-generation biomarkers for AMI diagnosis and management. Hypertrophy was successfully induced in immortalized human cardiomyocytes (T0445) by 200 nM ET-1 and 1 μM Ang II. The protein profiles of hypertrophied cardiomyocyte secretomes were analyzed by nano-liquid chromatography with tandem mass spectrometry and differentially expressed proteins that have been identified by Ingenuity Pathway Analysis. The levels of 32 proteins increased significantly (>1.4 fold), whereas 17 proteins (<0.5 fold) showed a rapid decrease in expression. Proteomic analysis showed significant upregulation of six 14-3-3 protein isoforms in hypertrophied cardiomyocytes compared to those in control cells. Multi-reaction monitoring results of human plasma samples showed that 14-3-3 protein-zeta levels were significantly elevated in patients with AMI compared to those of healthy controls. These findings elucidated the role of 14-3-3 protein-zeta in cardiac hypertrophy and cardiovascular disorders and demonstrated its potential as a novel biomarker and therapeutic strategy.

IVA는 상염색체 열성의 유전방식을 보이는 leucine 대사 장애 질환이자 대표적인 유기산 혈증이다. IVD 유전자의 돌연변이에 의한 isovaleryl-CoA dehydrogenase 효소의 결핍이 질환 발생의 원인이다. Isovaleryl-CoA dehydrogenase 효소가 결핍되면 isovaleryl-CoA의 대사물질이 비정상적으로 체내에 축적되어 대사성 산증 및 고암모니아혈증 등의 급성 대사성 위기와 발달지연, 성장지연, 및 경련성질환 등의 만성 합병증을 초래할 수 있기 때문에, 급성 대사성 위기 및 만성합병증의 발생을 예방하기 위해 조기 진단에 따른 적절한 치료의 도입이 중요하다. 현재 IVA은 국내에서 시행되는 탠덤 매스 스크리닝법을 이용한 신생아 대사질환 선별검사 항목에 포함되어 있으며, C5의 상승으로 의심할 수 있다. 그러나 SBCAD 결핍증 혹은 pivalic acid 유래물이 포함된 항생제를 투여한 경우에도 C5의 상승이 동반될 수 있기 때문에, 감별진단 및 확진을 위한 추가적인 생화학적, 유전학적 검사가 필수적이다.

Purpose: The purpose of the present study was to investigate the pharmacokinetics of urea, a new potential diagnosis reagent of Helicobacter pylori infection. Methods: Considering the mechanism of urea breath test, we determined the excretion of urea in expired air after its oral administration in rats and beagle dogs at the dose of 2 mg/kg (including 50 mCi/mmol $^{14}C$-urea 50 ${\mu}Ci/kg$ for rats and 13.5 ${\mu}Ci/kg$ for dogs). Results: Urea was rapidly disappeared from the blood circulation by 1 hr after its i.v. bolus injection, followed by a slow disappearance by 24 hr. The half-lives at the distributive phase ($t_{1/2{\alpha}}$) and post-distributive phase ($t_{1/2{\beta}}$) were 2 min and 6 hr, respectively. The bioavailability of urea was 64.3% after its oral administration. The values of the volume of distribution ($V_{dss}$) and the total body clearance ($CL_t$) after the oral administration were compatible with those after i.v. administration. The recovery of urea in the bile was about 0.1% of the dose by 24 hr after its oral administration. Urea was extensively eliminated in the urine by 48 hr. The recovery ratios of urea in the urine and expired air were about 86.8% and 2.99% of the dose by 48 hr, respectively. Moreover, urea was mostly distributed from the blood circulation to the kidney, followed by being eliminated in the urine without metabolism. The concentration of urea in the kidney was 4.0 times higher than that of plasma at 40 min after its oral administration. Conclusions: These findings indicated that oral route appears to be available for the administration of urea. Orally administered urea, thus, was considered to be useful for the diagnosis of Helicobacter pylori infection.
