Objectives Asthma is an allergic disease that frequently occurs in children. This study aims to research acupuncture and acupoint-application treatment of pediatric asthma. Methods We got 53,653 search results with searching word 'child' 'children' 'pediatric' 'juvenile' 'adolescence' 'baby' 'infant' 'asthma' in Pubmed and got 147 results among them with searching word 'acupuncture' 'acupoint application'. We selected 13 articles among them which were seem to be related to this study. We classified these studies according to the type of study, the treatment methods and treatment outcomes. Results There were few studies about acupuncture and acupoint application on pediatric asthma. According to current research, conducting acupuncture and acupoint application treatment on pediatric asthma patient is recommended. Especially, acupoint application and laser acupuncture treatment were important to consider as treatment options on pediatric asthma patients for non-invasive way and less painful to children. Conclusions For the study on acupuncture and acupoint application treatment in pediatric asthma, it is necessary that we conduct research on various merit of acupuncture. More clinical data would be needed to prove the effects of acupuncture and acupoint application treatment in pediatric asthma.

Ultrahigh performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI- MS/MS) provides a high-speed method to screen a large number of samples for small molecules with specific properties. In this study, UPLC-ESI-MS/MS with multiple reaction monitoring (MRM) was employed to screen urinary phospholipid (PL) content for biomarkers of prostate cancer. From lists of urinary PLs structurally identified using nanoflow LC-ESI-MS/MS, 52 PL species were selected for quantitative analysis in urine samples between 22 cancer-free urologic patients as controls and 45 prostate cancer patients. Statistical treatment of data by receiver operating characteristic (ROC) analysis yielded 14 PL species that differed significantly in relative concentrations (area under curve (AUC) > 0.8) between the two groups. Among PLs present at higher levels in prostate cancer urine, phosphatidylcholines (PCs) and phosphatidylinositols (PIs) constituted the major head group PLs (3 PCs and 7 PIs). For technical reasons, PL species of low abundance may be underrepresented in data from UPLC-ESI-MS/MS performed in MRM mode. However, the proposed method enables the rapid screening of large numbers of plasma or urine samples in the search for biomarkers of human disease.

Numerous biochemical molecules have been implicated in the development of muscular atrophy. However, control mechanisms associated with muscular disease are not clear. The present study was conducted to investigate gene expression profiles of rat muscle during the denervation to atrophy transition processes. We isolated total RNA from rats suffering from partial muscle atrophy (P) and electromyostimulated atrophy (PE) and synthesized cDNA using annealing control primers. Using 20 ACPs for PCR, we cloned 18 DEGs using TOPO TA cloning vector, sequenced, and analyzed their identities using BLAST search. Sequences of 14 clones significantly matched database entries, while one clone was ESTs, and 3 clones were unidentified. Different expression profiles of selected DEGs between P and PE were confirmed. The troponin T, Fkbp1a, RGD1307554, Phtf1, Atp1a1 and Commd3 were highly expressed genes in the P and PE groups, while Krox-25 and TCOX2 were only expressed genes in the P group, the Sv2b and Marcks were only expressed genes in PE group. also, Cox8h was highly expressed genes in PE groups. The ASPH, ND1, and ARPL1 were highly expressed genes in the P and PE groups. List of genes obtained from the present study might provide an insight for the study of mechanism regulating muscle atrophy and electrostimulated muscle atrophy transitions. These data suggest that troponin T, Fkbp1a, RGD1307554, Phtf1, Atp1a1, and Commd3 are potentially useful as clinical biomarkers of age-related muscle atrophy and dysfunction.

3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (Statins) are potent inhibitors of cholesterol biosynthesis. Cholesterol-lowering therapy using statins significantly reduces the risk of coronary heart disease. Various discovery of statins as bone anabolic agents has spurred a great deal of interest among both basic and clinical bone researchers. In-vitro and some animal studies suggest that statins increase the bone mass by enhancing bone morphogenetic protein-2 (BMP-2)-mediated osteoblast expression. Clinical and animal test results of statins focusing on the prevention and treatment of bone fractures was collected. Three independent literature searches were performed by using from January 1, 2002 to September 2008 for clinical and animal test results. Search term included statins, HMG-CoA reductase inhibitors, pleiotropic effects, fracture, osteoporosis and clinical and animal test. No consensus has been reached whether clinical use of statins has beneficial effects on bone health, partly due to lower statin concentrations because of first-pass metabolism by the liver. Experimental use of statins as stimulators of bone formation suggests that they may have widespread applicability in the field of orthopaedics. With their combined effects on osteoblasts and osteoclasts, statins have the potential to enhance resorption of synthetic materials and improve bone ingrowth. In conclusion, The use of statins in the prevention and treatment of bone fractures requires further study. But observational studies suggest that statins for decreasing bone fractures including osteoporosis have to be considered local direct administration like transdermal or subcutaneous type over oral adminstration.

Methylmercury (MeHg), one of the heavy metal compounds, can cause severe damage to the central nervous system in humans. Many reports have shown that MeHg is poisonous to human body through contaminated foods and has released into the environment. Despite many studies on the pathogenesis of MeHg-induced central neuropathy, no useful mechanism of toxicity has been established so far. This study, using of suppression subtractive hybridization (SSH) method, was peformed to identify differentially expressed genes by MeHg in SH-SY5Y human neuroblastoma cell line. We prepared to total RNA from SH-SY5Y cells treated with solvent (DMSO) and $6.25\;{\mu}M\;(IC_{50})$ MeHg and performed forward and reverse SSH. Differentially expressed cDNA clones were screened by dot blot, sequenced and confirmed that individual clones indeed represent differentially expressed genes with real time RT-PCR. These sequences were identified by BLAST homology search to known genes or expressed sequence tags (ESTs). Analysis of these sequences may provide an insight into the biological effects of MeHg in the pathogenesis of neurodegenerative disease and a possibility to develop more efficient and exact monitoring system of heavy metals as ubiquitous environmental pollutants.

The authors developed a comfortable program for routine work of surgical pathology. We used IBM PC(80386) and Foxbase plus program. The main function of this program was automatic coding and concurrent surgical report printing. During gross printing, previous biopsy number and its diagnosis were automatically searched and printed below gross description. The reported datas were stored during surgical report printing simultaneously, and thus the typist's workload became considerably reduced. Search for specific cases could be performed by patient's name, surgical number, hospital number, diagnostic code numbers(SNOMED code microglossary), and certain disease entities on very short duration.

Each year Malaria affects over 200 million people worldwide. Particularly, African continent is highly hit by this disease. According to many researches, this continent is ideal for Anopheles mosquitoes which transmit Malaria parasites to thrive. Rainfall volume is one of the major factor favoring the development of these Anopheles in the tropical Sub-Sahara Africa (SSA). However, the surveillance, monitoring and reporting of this epidemic is still poor and bureaucratic only. In our paper, we proposed a method to fast monitor and report Malaria instances by using Social Network Systems (SNS) and precipitation volume in Nigeria. We used Twitter search Application Programming Interface (API) to live-stream Twitter messages mentioning Malaria, preprocessed those Tweets and classified them into Malaria cases in Nigeria by using Support Vector Machine (SVM) classification algorithm and compared those Malaria cases with average precipitation volume. The comparison yielded a correlation of 0.75 between Malaria cases recorded by using Twitter and average precipitations in Nigeria. To ensure the certainty of our classification algorithm, we used an oversampling technique and eliminated the imbalance in our training Tweets.

Objectives: This systematic review aimed to put the case reports of lung cancer on Korean medicine (KM) together and adopt the results in clinical practice. Methods: Researches were searched using the PubMed, EMBASE, OASIS, KoreanTK, KISTI, RISS, KISS, and NDSL. The search term were 'lung cancer' and KM. There was no restriction in year. Results: 1. Among the 48 studies, 68 patients were reported in total. The types of lung cancer were non-small-cell lung cancer (n=41) and small-cell lung cancer (n=6). 2. The number of patients who received KM therapy alone was 40. On the other hand, 25 patients were treated with KM and chemotherapy simultaneously. All case reports used herbal medicine except 2 studies. Other types of treatment were acupuncture, moxibustion, pharmacopuncture, cupping, meditation, etc. 3. Several efficacy evaluation variables were used such as tumor size, changes of symptoms, duration of survival, the quality of life, and so on. The safety was evaluated by checking adverse effects using blood test. 4. Regarding the tumor response, partial response was reported in 12 cases, stable disease was in 22 cases, 50% of the total cases, which is a high level of tumor response. Furthermore, all 11 cases with the evaluation on the length of survival showed prolonged survival than the expectancy of corresponding stage, with the stable quality of life. Conclusion: We have found that the applicability of KM for treatment of lung cancer through this review. Evidence based medicine can be realized by checking cases and applying them in clinical practice.

Exosomes have gained the attention of the scientific community because of their role in facilitating intercellular communication, which is critical in disease monitoring and drug delivery research. Exosome research has grown significantly in recent decades, with a focus on the development of various technologies for isolating and characterizing exosomes. Among these efforts is the use of matrix-assisted laser desorption ionization (MALDI) mass spectrometry (MS), which offers high-throughput direct analysis while also being cost and time effective. MALDI is used less frequently in exosome research than electrospray ionization due to the diverse population of extracellular vesicles and the impurity of isolated products, both of which necessitate chromatographic separation prior to MS analysis. However, MALDI-MS is a more appropriate instrument for the analytical approach to patient therapy, given it allows for fast and label-free analysis. There is a huge drive to explore MALDI-MS in exosome research because the technology holds great potential, most notably in biomarker discovery. With methods such as fingerprint analysis, OMICs profiling, and statistical analysis, the search for biomarkers could be much more efficient. In this review, we highlight the potential of MALDI-MS as a tool for investigating exosomes and some of the possible strategies that can be implemented based on prior research.
