RESUMEN
Talents are the main force for the development of traditional Chinese medicine(TCM), and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present, we are still exploring and developing in the fields of the formulation, implementation and evaluation indicators of TCM talent evaluation system. However, there are shortcomings and difficulties. For instance, insufficient stratification in the evaluation, excessive emphasis on the quantity of achievements, neglecting the quality of the achievements and the actual contribution, imperfect assessment indicators, and the weak characteristics of TCM. Therefore, national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard, in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value, ability and contribution. For the evaluation of TCM clinical talents, China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM(CCCL-TCM), which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry, and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.
RESUMEN
Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine (TCM) mainly involves peripheral vestibular diseases of Western medicine, such as Meniere's disease, benign paroxysmal positional vertigo, vestibular neuritis, and vestibular migraine, being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo, aural vertigo affecting the quality of life, aural vertigo not relieved after surgery, aural vertigo with complex causes, and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM: Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo, the control and mitigation of the symptoms, and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.
RESUMEN
Aging is a major risk factor for cognitive impairment. Aerobic exercise benefits brain function and may promote cognitive health in older adults. However, underlying biological mechanisms across cerebral gray and white matter are poorly understood. Selective vulnerability of the white matter to small vessel disease and a link between white matter health and cognitive function suggests a potential role for responses in deep cerebral microcirculation. Here, we tested whether aerobic exercise modulates cerebral microcirculatory changes induced by aging. To this end, we carried out a comprehensive quantitative examination of changes in cerebral microvascular physiology in cortical gray and subcortical white matter in mice (3-6 vs. 19-21 months old), and asked whether and how exercise may rescue age-induced deficits. In the sedentary group, aging caused a more severe decline in cerebral microvascular perfusion and oxygenation in deep (infragranular) cortical layers and subcortical white matter compared with superficial (supragranular) cortical layers. Five months of voluntary aerobic exercise partly renormalized microvascular perfusion and oxygenation in aged mice in a depth-dependent manner, and brought these spatial distributions closer to those of young adult sedentary mice. These microcirculatory effects were accompanied by an improvement in cognitive function. Our work demonstrates the selective vulnerability of the deep cortex and subcortical white matter to aging-induced decline in microcirculation, as well as the responsiveness of these regions to aerobic exercise.
RESUMEN
ObjectiveTo establish and evaluate a mouse model of heart failure with Qi deficiency syndrome. MethodForty-four KM mice were randomly divided into sham operation group, model group, and modified Si Junzitang group (12.89 g·kg-1). The model group and the modified Si Junzitang group underwent thoracic aortic constriction (TAC), while the sham operation group only underwent suture without constriction. Echocardiography and pathological examination were used to assess the heart failure model and evaluate the pharmacological effects. Macroscopic characterization, microscopic biology, and formula identification were conducted to collect general signs, body weight, open-field behavior, grip strength, mitochondrial ultrastructure, and other macroscopic and microscopic characteristics of mice. Mitochondrial fission and fusion protein expression were measured to determine the syndrome type. ResultEight weeks after TAC, compared with the sham operation group, the model group showed a significant decrease in left ventricular ejection fraction (LVEF) (P<0.01), and modified Si Junzitang improved LVEF in mice (P<0.05). Hematoxylin-eosin (HE) staining of the heart showed inflammatory cell infiltration and thickening of blood vessel walls in the model group, which was significantly improved by modified Si Junzitang. After 6-8 weeks, compared with the sham operation group and the modified Si Junzitang group, the model group exhibited significant hair loss, hair yellowing, decreased activity, and depression. Moreover, compared with the sham operation group, the model group had a significantly lower increase in body weight (P<0.05), while the modified Si Junzitang group showed a significant increase in body weight (P<0.05) compared with the model group. After 6-8 weeks, compared with the sham operation group, the model group showed a significant decrease in open-field distance and speed (P<0.05), while the modified Si Junzitang group exhibited significantly improved open-field distance and speed in the 8th week (P<0.05). After 6-8 weeks, compared with the sham operation group, the model group exhibited a significant decrease in maximum grip strength (P<0.05), while the modified Si Junzitang group showed a significant increase in maximum grip strength 8 weeks after TAC (P<0.05). Transmission electron microscopy of the gastrocnemius muscle showed uneven muscle tissue matrix, mitochondrial swelling, increased volume, matrix dissolution, ridge loss, and vacuolization in the model group, while modified Si Junzitang improved mitochondrial swelling, ridge fracture, and matrix vacuolization. Western blot analysis showed that the expression of the kinetic associated protein 1 (DRP1) in the gastrocnemius muscle of the model group significantly increased (P<0.01), and the expression of mitochondrial fusion hormone 1 (MFN1) significantly decreased (P<0.05) as compared with those in the sham operation group. Furthermore, compared with the model group, the modified Si Junzitang group exhibited a significant decrease in the expression of DRP1 (P<0.05) and a significant increase in MFN1 expression (P<0.01). ConclusionMice exhibited significant manifestations of qi deficiency syndrome 6-8 weeks after TAC, accompanied by abnormal mitochondrial morphology and function in the gastrocnemius muscle, which were significantly improved by modified Si Junzitang.
RESUMEN
OBJECTIVE To study the effect of Longsheng zhi capsule on lear ning and memory ability of vascular dementia model rats and explore its mechanism based on metabonomics. METHODS Totally 90 SD rats were randomly divided into sham operation group ,model group ,Dihydroergotoxin mesylate tablet group (positive control ,0.54 mg/kg),Longshengzhi capsule high-dose,medium-dose and low-dose groups (2.16,1.08 and 0.54 g/kg),with 15 rats in each group. In addition to sham operation group (only threading without ligation ),the vascular dementia model was prepared by permanent ligation of bilateral common carotid arteries in each group ,which was administered by gavage for 28 d. Morris water maze test was used to determine the learning and memory ability of rats ;hematoxylin eosin (HE)staining was used to observe the histopathological changes of hippocampus;the serum levels of superoxide dismutase (SOD),malondialdehyde(MDA)and glutathione peroxidase (GSH-Px) were detected ;the serum metabolic map was analyzed by ultra high performance liquid chromatography quadrupole time of flight tandem mass spectrometry (UPLC-Q-TOF/MS),the specific metabolites were screened by multivariate statistical analysis ,and the metabolic pathway was enriched and analyzed. RESULTS Morris water maze test showed that compared with model group ,the escape latency of rats in each administration group was significantly shortened ,the number of crossing the platform was significantly increased ,and the residence time in the target quadrant was significantly prolonged (P<0.01 or P< 0.05). The results of serum biochemical indexes showed that compared with model group , the s erum level of SOD increased significantly in Dihydroergotoxine mesylate tablet group and Longshengzhi capsule high-dose group ,the serum level of GSH-Px increased significantly while the MDA level decreased significantly in each administration group (P<0.05 or P<0.01). HE staining showed that Longshengzhi capsule could improve the histopathological damage of hippocampus in vascular dementia model rats. A total of 14 differential metabolites were screened and identified by UPLC-Q/TOF-MS and orthogonal partial least squares discriminant analysis model (VIP>1 and P<0.05). The results of metabolic pathway enrichment analysis showed that the metabolic pathways involved in vascular dementia in rats mainly included vitamin B 6 metabolism,fatty acid metabolism and steroid hormone biosynthesis. CONCLUSIONS Longshengzhi capsule can improve the learning and memory ability of rats caused by vascular dementia. Its effect may be related to improving the oxidative stress injury caused by lipid accumulation in the process of vascular dementia. The metabolic pathways involved mainly include vitamin B 6 metabolism,fatty acid metabolism and steroid hormone biosynthesis.
RESUMEN
ObjectiveTo explore the effect of sweroside on the protection of cardiac systolic/diastolic function during ischemia/reperfusion (I/R) injury. MethodTwenty-four healthy male SD rats were randomly divided into control group, model group, 10 μmol·L-1 sweroside group and 1 μmol·L-1 digoxin group. The I/R injury was modeled by Langendorff and ligation of the left anterior descending coronary artery. The infarct size in each group was measured by 2,3,5-triphenyltetrazolium chloride (TTC) staining and hemodynamic parameters such as left ventricular diastolic pressure (LVDP), left ventricular end-diastolic pressure (LVEDP), left ventricular end-systolic pressure (LVESP), maximum rate of rising of left ventricular pressure (+dp/dtmax) and maximum rate of decreasing of left ventricular pressure (-dp/dtmax) of rat isolated heart were detected by Powerlab. In addition, neonatal rat cardiomyocytes (NRCMs) were isolated and randomly divided into control group, model group, 1 μmol·L-1 sweroside group and 10 μmol·L-1 sweroside group. Hypoxia/reoxygenation (H/R) injury model was established. Cardiac systolic function and calcium transients were examined by multi-functional cell imaging analyzer and laser confocal microscope. Furthermore, real-time polymerase chain reaction(Real-time PCR) was used to verify the mRNA expression of excitation-contraction coupling genes such as L-type calcium channel (Cacnb2), cytochrome c oxidase subunit 6A2 (Cox6a2), troponin (Tnnc1, Tnni3, Tnnt2), actin (Actc1), and myosin (Myh6, Myl2, Myl4) according to the results of previous transcriptome sequencing and literature investigation. Differentially expressed genes were subjected to cluster analysis. ResultCompared with the conditions in the control group, increased cardiac infarction size (P<0.01) and LVEDP (P<0.01) and decreased LVDP (P<0.01) and LVESP (P<0.05) were observed in the model group, with +dp/dtmax of increasing trend while -dp/dtmax decreasing. Moreover, the cell viability, heart rate and contraction amplitude of NRCMs was reduced (P<0.01), while the contraction duration, time to peak and relaxation time was elevated (P<0.01) in the model group. Interestingly, sweroside could reverse these indicators (P<0.05). In addition, the expression of Cacnb2, Cox6a2, Tnnc1, Tnni3, Tnnt2, Actc1, and Myh6, Myl2, and Myl4 was down-regulated in the model group (P<0.05, P<0.01), but sweroside could up-regulate the expression of the above genes (P<0.05). ConclusionSweroside effectively regulated Ca2+ level in NRCMs, enhanced cardiac systolic function, and protected against H/R injury by regulating excitation-contraction coupling.

RESUMEN
Objective To study the disseminated Staphylococcus aureus infection (DSAI) in children. Method Clinical features, treatment and prognosis data of 14 children with DSAI admitted to Yuying Children’s Hospital Afifliated to Wenzhou Medical University from January 2006 to December 2013 was retrospectively reviewed. Results 14 children with DSAI occurred in community, median age:15m (range 6d–13y);50%male (7 cases). All patients presented with fever. Addition to fever, the ifrst symptom was skin and soft tissue infections (SSTIs,6 cases) as well as limb and/or joint pain (5 cases). Among children with DSAI, white blood cell count and C-reactive protein values increased signiifcantly. Pyogenic infection site were skin and soft tissue in 12 cases (85.7%), pulmonary (12 cases), bone (4 cases), joint (3 cases), central nervous system (3 case), and pericardium (1 case). SSTIs concurrent with pulmonary infection was found in 10 cases (71.4%). Incision and drainage of skin and soft tissue abscesses were performed in 9 cases, joint debridement and vacuum sealing drainage (VSD) in 3 cases, osteomyelitis debridement and VSD in 3 cases, and closed chest drainage in 3 cases. All cases received vancomycin and/or linezolid treatment, 5 cases supplemented by rifampicin, and intravenous immune globulin therapy was administered in 11 cases. Clinical manifestations were cured or improved in 12 cases (85.7%). Conclusions Clinical diagnosis of DSAI in children needs to be vigilant. SSTIs, bone and joint infections were major precipitating factors. Intravenous immune globulin therapy was supplemented to the application of antibiotics, which might get better clinical outcomes in children.
RESUMEN
The protective effect of an alpha-glucan (designated here as MT-α-glucan) from fruit body of maitake (Grifola frondosa) on NIT-1 pancreatic ß-cells damaged by streptozotocin (STZ) in vitro was investigated. The cell viability, insulin secretion, the activity of superoxide dismutase (SOD), glutathione peroxidase (GSHpx) and the content of reduced glutathione (GSH) increased significantly when the cells were incubated with MT-α-glucan (400, 200 µg ml(-1)). The content of malondialdehyde (MDA), nitric oxide (NO) production, and the activity of NO synthase (NOS), inducible NOS (iNOS) decreased significantly when the cells were incubated with MT-α-glucan. The destructive changes of NIT-1 cells ameliorated when incubated with MT-α-glucan under microscopic observation. These data suggested that MT-α-glucan had obvious protective effect on NIT-1 pancreatic ß-cells damaged by STZ, which might be related to its effects of decreasing levels of ß-cell-destroying factors such as oxidative stress and NO synthesis.

RESUMEN
Objective To compare the changes in optic disc parameters after intraocular pressure (lOP) reduction between primary angle-closure glaucoma (PACG) and primary open angle glaucoma (POAG) eyes, and to determine if there is a difference of lamina eribrosa compliance between POAG and PACG. Design Prospective comparative study. Participants 36 PACG (49 eyes) and 35 POAG (49 eyes). Methods Patients underwent Heidelberg Retina Tomography (HRT Ⅱ) and Humphrey visual field test before IOP reduction. HRT and Humphrey visual field test were repeated one month after the IOP was reduced by laser, anti-glaucomatous medications or surgery treatment. Factors that affected the change in IOP were assessed including age, pretreatment IOP, IOP reduction, initial cup: disc ratio and diagnosis (POAG/PACG). Main outcome measures Changes of HRT parameters including cup area, mean cup depth, cup volume, and rim area after IOP reduction. Results The cup area, mean cup depth and cup volume decreased, and rim area in-creased significantly when the IOP was reduced (P<0.05), but there were no significant differences in the changes between PACG and POAG patients (P>0.05). Changes of these four HRT parameters were related to the amount of IOP reduction and the baseline ratio of cup to disc(P>0.05), but not related to age and pre-treatment IOP (P<0.05). Conclusions The cup became smaller and the rim area in-creased after IOP lowering with treatment in both POAG and PACG, and the magnitude of the change was similar in both groups. The lamina cribrosa compliance may not be different between POAG and PACG. (Ophthalmol CHN, 2009, 18: 264-269)
RESUMEN
OBJECTIVE: To establish an animal model of myocardial ischemia with blood stasis syndrome in mini-swines. METHODS: An animal model of myocardial ischemia was established in mini-swines by oppressing the coronary artery through the expansion of inner layer of Ameroid constrictor and the Ameroid constrictor was implanted into the distal end of the initial part of the first branch of interventricular septum of ramus descendens anterior arteriae coronariae sinistrae. Dynamic observation of behavior changes, general health status and changes of hemorheological parameters in the mini-swines were made after operation. RESULTS: The coronary angiography showed that the stenosis rate in ischemic group was more than 75% four weeks after operation. Compared with before operation and sham-operated group, there were great changes of behavior, general health status, tongue color and hemorheological parameters in ischemic group (P<0.05). CONCLUSION: The animal model of myocardial ischemia with blood stasis syndrome in mini-swines was established successfully 4 weeks after operation. The pathological process in the animal model is similar to that in the patients with chronic myocardial ischemia. So this model can be adopted in the research of myocardial ischemia with blood stasis syndrome.

RESUMEN
Objective: To investigate the syndrome property of myocardial Ischemic, and evaluate the relevant informations of qi-deficiency. Methods: SD rats were subjected to either proximal LAD ligation or sham operation. The respiratory rate in both resting state and post-stress were counted. 20 rats (10 in each group) were subjected to forced swimming test (FST) to measure the exhaustive swimming time in every time point Echocardiography was used to evaluate the cardiac function in rats at each time point. Results: Compared with sham operation group, the respiratory rate in the resting state was slower, but faster under post-stress, the exhaustive swimming time was shorter, and the cardiac function of rats was significant decreasing in model group during the period from 7th day to 60th day after operation. The exhaustive swimming time was much shorter, and the relevant information of blood stasis was abnormal in the model group during the period from 7th day to 28th day after operation, when compared with the sham group. Conclusion: Myocardial ischemic rats induced by LAD ligation had both qi-deficiency and blood stasis indications, can be diagnosed as the syndrome of qi-deficiency and blood stasis during the period from 7th day to 28th day after operation. The model rats only had the qi-deficiency indications during the period from 45th day to 60th day after operation, so can be diagnosed as the qi-deficiency syndrome.
