OBJECTIVETo explore the clinical effects of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine ( Fuchunsan ) on the treatment of postburn hyperplastic scar.
METHODSSixty-three patients with hyperplastic scar after burn injury hospitalized from February 2012 to June 2014 in our department were treated with lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan). Patients were divided into early stage group (E, n = 35), middle stage group (M, n = 25), and late stage group ( L, n = 3) according to the formation time of scar, which was respectively 3 weeks to 3 months, longer than 3 months and less than or equal to 6 months, and 3 to 15 years in groups E, M, and L. The number of times of laser treatment of patients in each group was recorded. The degree of scar pain in patients of the three groups was assessed by the Numerical Rating Scale (NRS) before treatment and after treatment for 1, 2, and 3 times. The scar condition of patients in groups E and M was assessed by the Vancouver Scar Scale (VSS) before treatment and after treatment for 1, 3, and 5 times. Patients in group L did not receive VSS assessment but were evaluated by clinical observation only. Photos of scar in treating area were taken before treatment and after treatment for 3 and 5 times to evaluate the clinical effect. Data were processed with t test.
RESULTSPatients in groups E and M were treated with laser for (4.8 ± 1.1) and (7.7 ± 2.1) times respectively. In group L, the treatment was stopped in 2 patients after laser treatment for 5 times, and 1 patient received laser treatment for 12 times. The degree of pain in patients of groups E and M was alleviated significantly after treatment for one time, and the number of patients scoring 1-4 point(s) in NRS increased from 5 cases to 38 cases. After treatment for 2 and 3 times, the increase in the number of patients scoring 1-4 point (s) in NRS was on a small scale. Before treatment and after treatment for 1 time, VSS scores of patients in groups E and M were similar (with values respectively 0.641 and 0. 082, P values above 0. 05). After treatment for 3 and 5 times, VSS scores of patients in group E were respectively (9.2 ± 0.8) and (7.0 ± 1.1) points, which were significantly lower than those in group M [ (9.7 ± 1.0) and (8.2 ± 1.0) points, with values respectively -1.993 and -4.433 , P < 0.05 or P < 0.01]. After treatment for 3 times, the rate of improvement in appearance was respectively 88.6% (31/35) and 72.0% (18/25) in groups E and M, and it was respectively 100.0% (35/35) and 96.0% (24/25) after treatment for 5 times. No significant effect in appearance was found in the 3 patients in group L.
CONCLUSIONSEarly application of lattice ultra pulse carbon dioxide laser combined with traditional Chinese medicine (Fuchunsan) for the treatment of postburn hyperplastic scar is effective.

Human bocavirus (HBoV) 1-4 have been detected both in respiratory and stool samples since the first HBoV was discovered in 2005. HBoV-1 is mostly associated with respiratory infection, while HBoV 2-4 are usually associated with intestinal tract infection. A variety of signs and symptoms have been described in patients with HBoV infection, including cough, wheezing, pneumonia, and diarrhea, but the research on pathogenic mechanism of HBoV is limited because HBoV cannot be cultured in vitro due to the lack of appropriate host cells. Three-dimensional epithelial cell culture, reverse genetics, and viral metagenomics are identified as novel tools that may promote the research on pathogenic mechanism of HBoV and the discovery of new viruses. This review summaries currently available diagnostic approaches such as electron microscopy, cell culture, PCR, and immunoassay in order to provide a method reference for indepth research on HBoV.

Human adenovirus (HAdV) is one of the most important pathogens in infants and young children with acute respiratory infections and other diseases. This article reviews the literature on HAdV, including its molecular biological characteristics, detection and typing, and pathogenic mechanism, the clinical features and epidemiological characteristics of HAdV-related diseases, and the prevention and control of HAdV infections. So far, 67 types of HAdV have been identified, including recombinant variants discovered in recent years. The major epidemic strains that cause acute respiratory infections are HAdV-3 and HAdV-7, both of which belong to the subgroup B. HAdV often leads to acute respiratory infections, but it also causes diseases of other systems. HAdV-related diseases have similar clinical manifestations as those caused by other respiratory viruses, but often accompanied by gastrointestinal symptoms. The pathogenic mechanism of HAdV remains unclear, especially for the new recombinant variants, due to few studies on their association with diseases. Because there are no prospective, large randomized controlled trials of HAdV infections, the treatment of HAdV infections is controversial. Vaccine is the most effective measure to reduce respiratory HAdV infections, but it is still not commercially available.

San'ao Decoction (SD) and its analogous formulas derived in the following generations are common used prescriptions for treating pulmonary diseases with principal symptoms such as cough and asthma. They are usually compatible with Chinese herbs for facilitating Fei, dispelling wind, resolving phlegm and fluid retention. Material bases in these formulas are mainly derived from Chinese drugs, but dissolution contents of active components are changed and new components are produced after compatibility. By multilevel effect evaluation, these analogous formulas all have commonness in ventilating Fei and superiorities of evidence-based derivation. The effect pathway of commonness was involved in cell structure protection, anti-inflammation, antioxidant, and immunoregulation.

In traditional Chinese medicine(TCM),abnormal and diseased conditions have been defined as Zheng Hou, a unique disease definition system in the context of holism. For over 3000 years the main clinical treatment method for TCM therapeutics has been so called Fang-ji, a TCM medicinal formula usually composed of several herbs and medical materials. The compositions of Fang-ji are based on the clinical practice under the guidelines of "bian-zheng-lun-zhi" and the principles of "Jun-chen-zuo-shi". Each Zheng is treated with a correspondingly-individualized Fang-ji.The modern approach to the study of Fang-ji pharmacology,however,has been focusing on the isolation and identification of individual active components for cellular and molecular targets. Although this approach has led to the development of many new monomers purified from Fang-ji as new drugs widely used in clinical practice such as the an-timalarial artemsinin,which has earned a Nobel Prize,the pharmacological bases of these purified effective monomers or active components have lost the TCM characteristics and are far different from the phar-macological theory and clinical applications of Fang-ji,in terms of the principles of"bian-zheng-lun-zhi"and "Jun-chen-zuo-shi". Here we introduce the emerging pharmacophenophenics as a systematical paradigm for the pharmacological study of Fang-ji.Pharmacophenomics studies the orchestrated multi-target pharmacology of combination therapy.With well-defined molecular mechanisms of Zheng Hou at the level of multi-omics and a suite of new phenomics technologies and platforms, the pharmacophe-nomics may be used to characterize the drug-response phenome of Fang-ji and to identify the corre-sponding multiple therapeutic targets according to the TCM theory of Jun-chen-zuo-shi.Pharmacophe-nomic study of Fang-ji will also lay a theoretical foundation for the new science of precision medicine.

BACKGROUND: It remains unclear whether ectomesenchymal cells also derived from neural crest stem cell in mammals.OBJECTIVE: To understand the specific markers and differentiation directions of maxillofacial and mandibular processes progenitor cells,and to explore the source and differentiation phenotype of ectomesenchymal stem cells.METHODS: The expression and changes of expression profiles of rat ectomesenchymal cells at E9.5,E10.5,E11.5,and E12.5days were observed by immunohistochemistry and flow cytometry.RESULTS AND CONCLUSION: The progenitors expressed multi-lineage markers,including neural system and several rnesenchymal tissue types,importantly the facts that molecule profiles were changed with time prolonged,suggesting these progenitors were in active differentiating stage,so they were stem like cells or contain stem like cells.Moreover,small populations(2%-3%)of CD57 and P75 phenotypes were detected by flow cytornetry,suggesting that ectomesenchymal stem cells were derived from neural crest,which maintained a quantitative stabilization though it is gradually differentiate after localization.

Euphorbia kansui (EK) is a toxic herbal drug, and often used after vinegar-processing to reduce its toxicity. In present study, a 1H-NMR based metabonomic approach was used to evaluate the detoxification effect of vinegar-processed EK. The water extracts of EK and VEK were administered orally to male SD rats at doses of 9 g x kg(-1) x d(-1) for 1 week, respectively, and one more week observation was further conducted. The control group was orally given with saline. Histopathological studies of liver samples on the 8th and 15th day were conducted, and the metabolites of rat urine and liver were analysed by 1H-NMR. Histopathological studies of liver samples from EK and VEK treated rats showed no negative impacts. In metabonomic analyses of urines, changes of metabolites indicated liver damages, kidney lesions and imbalance of gut microbes in the second week. VEK-treated rats showed a quite lower toxicity compared with EK-treated ones. The present study revealed that the metabonomic approach might be helpful for the evaluation of toxicity of EK and detoxic effect of VEK.
