RESUMO

OBJECTIVES: To observe the clinical efficacy of the spirit-regulation method of Jin's three-needle therapy on post-stroke anxiety and its effects on the hypothalamus-pituitary-adrenal (HPA) axis. METHODS: Fifty-four patients with post-stroke anxiety were divided into spirit regulation (Jin's three needle therapy) group and sham-acupuncture group according to the random number table method, 28 cases in the spirit regulation and 26 cases in the sham-acupuncture group. The patients of the two groups received the same regimen of basic medication and rehabilitation, and the same acupoint prescription was adopted, including Sishenzhen (extra points, 1.5 cun to Baihui [GV20] at 3, 6, 9 and 12 o'clock positions), Shenting (GV24), Yintang (EX-HN3), and bilateral Shenmen (HT7), Sanyinjiao (SP6), Hegu (LI4) and Taichong (LR3). The true acupuncture was delivered in the spirit regulation group and the sham acupuncture operated in the sham-acupuncture group. One treatment lasted for 30 min, once daily, 5 times a week. The duration of treatment was 3 weeks in the trial. Before treatment and on day 10 and day 21 of treatment, the changes in the score of Hamilton anxiety scale (HAMA) and that of National Institutes of Health Stroke Scale (NIHSS) were compared between the two groups separately. Using ELISA, the contents of adrenocorticotropin (ACTH) and cortisol (CORT) in the serum were detected, and the adverse reactions were recorded. RESULTS: In the within-group comparison before and after treatment, HAMA score and NIHSS score dropped on day 10 and day 21 after treatment in the spirit regulation group (P<0.05);HAMA score and NIHSS score in the sham-acupuncture group were decreased on day 21 of treatment (P<0.05). After 21 days of treatment, HAMA score and NIHSS score in the spirit-regulation group were decreased significantly than those in the sham-acupuncture group (P<0.05) and the contents of ACTH and CORT in the serum decreased when compared with those before treatment and those of the sham-operation group (P<0.05). No obvious adverse events occurred in the spirit-regulation group and the sham-acupuncture group. CONCLUSIONS: Using sham acupuncture as a control, it is preliminarily confirmed that the spirit regulation method of Jin's three-needle therapy is effective on post-stroke anxiety. In association of the downtrend of serological indicators, it is speculated that the underlying mechanism of this therapy is related to HPA axis.

RESUMO

OBJECTIVE: To observe the effect of standardized Jin's three-needle therapy on limb motor function and nerve function defect in stroke patients, and to evaluate the placebo control method. METHODS: A total of 66 patients with stroke were randomly divided into a Jin's three-needle group (33 cases, 3 cases dropped off) and a placebo needle group (33 cases, 4 cases dropped off). All the patients were treated with conventional medication and rehabilitation treatment. In addition, the patients in the Jin's three-needle group were treated with standardized Jin's three-needle therapy at temporal three points, spirit four points, hand three points, foot three points, upper extremity spasm three points, lower extremity spasm three points, etc.; while the patients in the placebo needle group were treated with placebo needling at identical points. All the treatments were given once a day, 5 days a week, and 3-week treatment was given with an interval of 2 days between weeks. The scores of Fugl-Meyer assessment scale (FMA) and National Institutes of Health stroke scale (NIHSS) were observed before treatment, 10 d and 21 d into treatment, and the blind evaluation was conducted after treatment. RESULTS: On the 10 d and 21 d into treatment, the FMA scores in both groups were higher than those before treatment (P<0.01), and the NIHSS scores were lower than those before treatment (P<0.01). On the 10 d and 21 d into treatment, the FMA scores in the Jin's three-needle group were higher than those in the placebo needle group (P<0.05); on the 10 d into treatment, the NIHSS score in the Jin's three-needle group was were lower than that in the placebo needle group (P<0.05). There was no significant difference between the two groups on judging the type of treatment (P>0.05), and the consistency with the real situation was poor (Cohen's kappa coefficient<0.20). CONCLUSION: The standardized Jin's three-needle therapy could effectively improve the limb motor function and nerve function defect in stroke patients. The placebo control method used in this study shows good clinical operability and masking effect.

RESUMO

Since ancient times, delaying aging, health, and longevity have been the universal wish of people. Nowadays, China gives top strategic priority to the development of people's health. How to maintain a healthy life and slow down the aging of the human body is a problem worthy of our attention. Human aging can be shown as cell senescence from the microscopic level. Cell senescence is a process in which cell proliferation and differentiation and physiological function gradually decline. It is a normal physiological function responsible for the removal of damaged cells and is the regeneration and recovery of tissues after injury or acute stress. Aging is an irresistible natural law. Although it is inevitable, it is possible to delay aging. Energy metabolism is an important basis of cell function, in which cells use nutrients such as sugar and fat to produce adenosine triphosphate (ATP). Mitochondria serve as the cell's power stations, where sugars, fats, and amino acids are eventually oxidized to release energy. Mitochondrial function decreases with age. Changes in mitochondrial dynamics, reactive oxygen species content, autophagy, and metabolites can cause dysfunction of electron transport chain and oxidative phosphorylation, and induce mitochondrial dysfunction. Mitochondrial dysfunction is one of the internal causes of many aging-related diseases, such as neurodegenerative diseases, Alzheimer′s disease, and atherosclerosis. Chinese medicine with few side effects and rich ingredients and health care moxibustion with safety and efficacy have been widely applied to the field of anti-aging. This study reviewed the effect of mitochondrial function on cell senescence, and retrieved, analyzed, and summarized research papers on the mechanism of traditional Chinese medicine (TCM) and moxibustion in delaying aging by affecting mitochondrial function, which is expected to provide new insights for further research in this field.

RESUMO

Older people are very likely to fall, which is a significant threat to the health. However, falls are preventable and are not necessarily an inevitable part of aging. Many different fall detection systems have been developed to help people avoid falling. However, traditional systems based on wearable devices or image recognition-based have many disadvantages, such as user-unfriendly, privacy issues. Recently, WiFi-based fall detection systems try to solve the above problems. However, there is a common problem of reduced accuracy. Since the system is trained at the original signal collecting/training place, however, the application is at a different place. The proposed solution only extracts the features of the changed signal, which is caused by a specific human action. To implement this, we used Channel State Information (CSI) to train Convolutional Neural Networks (CNNs) and further classify the action. We have designed a prototype to test the performance of our proposed method. Our simulation results show an average accuracy of same place and different place is 93.2% and 90.3%, respectively.

RESUMO

BACKGROUND: The treatment options for newly diagnosed non-small-cell lung cancer (NSCLC) patients with 1 to 3 synchronous brain metastases (BM) remain controversial. The current study aimed to comprehensively analyze the characteristics, local treatment paradigms, and survival outcomes in these populations. PATIENTS AND METHODS: A total of 252 NSCLC patients initially diagnosed with 1 to 3 synchronous brain-only metastases were enrolled onto this study. Local therapy (LT) to primary lung tumors (PLT) and BM included surgery, radiotherapy, or both. Median overall survival (mOS) was measured among patients who received LT to both PLT and BM (all-LT group), patients who were treated with LT to either PLT or BM (part-LT group), and patients who did not receive any LT (non-LT group). RESULTS: The mOS for all-LT (n = 70), part-LT (n = 113), and non-LT (n = 69) groups was 33.2, 18.5, and 16.8 months, respectively (P = .002). The OS rates at 5 years for the all-LT, part-LT, and non-LT groups were 25.5%, 16.2%, and 0, respectively. Multivariable analysis revealed that all-LT versus non-LT, pretreatment Karnofsky performance status > 70, histology of adenocarcinoma, thoracic stage I-II, EGFR mutation, ALK positive, and second-line systemic therapies were independent prognostic factors for improved mOS. CONCLUSIONS: The current study showed that LT for both PLT and BM is associated with superior OS in appropriately selected NSCLC patients initially diagnosed with 1 to 3 synchronous BM. Prospective trials are urgently needed to confirm this finding.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Toxicodendron vernicifluum (Stokes) F.A. Barkley (syn. Rhus verniciflua or vernicifera Stokes, Anacardiaceae) (RVS), the lacquer tree, also known as sumac, has been used in China, Japan and South Korea for thousands of years as a highly durable coating material and a traditional herbal medicine, which contains medicinal ingredients with anti-tumor, anti-inflammatory, antiviral, and anti-rheumatic activities. AIM OF THIS REVIEW: This review intends to provide a comprehensive and critical appraisal of RVS, including its phytochemical data, botanical and pharmacological literature that support its therapeutic potential in treatment on human diseases, with emphasis on the isolation of natural occurring compounds and detailed pharmacological investigations. MATERIALS AND METHODS: Specific information of RVS was collected by using the key words "Toxicodendron vernicifluum", "Rhus verniciflua Stokes", "Rhus vernicifera Stokes" and "Lacquer tree" through published scientific materials (including PubMed, ScienceDirect, Wiley, ACS, CNKI, Scifinder, Springer, Web of Science, Google Scholar, and Baidu Scholar) and other literature sources. RESULTS: The major phytoconstituents, 175 of which are presented in this review, including flavonoids, urushiols, terpenes, phenolic acids and other types of compounds, of which flavonoids and urushiols are main components. The extracts and isolates purified from RVS showed a wide range of in vitro and in vivo pharmacological effects, such as anti-cancer, anti-oxidation, anti-inflammatory, antimicrobial, tyrosinase inhibition and so on. CONCLUSION: The modern pharmacological research of RVS mainly focus on the pharmacological effects of crude extract or active constituents, of which the flavonoids are widely studied. However, there are few reports on the relationship between pharmacological effects and their structures. And at present, there is still a lack of researches that are of both effective and in-depth. Meanwhile, there is little research on quality control. Apart from the wood and lacquer, other botanical parts also need to be explored further. In addition to phenolic compounds, the study on other types of components in T. vernicifluum would start more sparks for the discovery of new bioactive principles.

RESUMO

Volatile oil is widely distributed in Chinese medicinal materials with complex chemical components. The main components are terpenes, aromatics, aliphatics, and nitrogen and sulfur containing. It has a variety of pharmacological activities. Such as antibacterial, anti-inflammatory, analgesic, anti-tumor, anti-oxidant, anti-aging and so on. It is widely used in medical and health care, agricultural efficiency enhancement, and daily products. In recent years, there have been a large number of studies on the pain relief of traditional Chinese medicine (TCM) essential oils, but there is no systematic generalization. The author found that the mechanism of TCM essential oils to exert analgesic effects mainly includes regulation of the central nervous system, anti-inflammatory and analgesic, antispasmodic and analgesic effects by consulting Chinese and foreign literatures in recent years, but the exact mechanism needs to be further verified. This article reviews the research progress of TCM essential oil pain relief from the aspects of pain classification, generation, analgesic mechanism and combination of other technologies, in order to provide reference for related research in the future.

RESUMO

A saponin (1) with gypsogenin as aglycone was isolated from the roots of Pulsatilla cernua. The aglycone of compound 1 was considered as gypsogenin which was rarely found in this genus. Its structure was predicted by NMR-based "mosaic" method rapidly, and further confirmed on the basis of spectroscopic data, including 2D NMR spectra and chemical evidence. This work suggested that NMR-based mosaic method is suitable for most of saponins from common species of genus Pulsatilla.

RESUMO

Objective:To investigate the effect of modified Si Junzitang on angiogenesis in transplanted tumor of H22 tumor-bearing mice. Method:The effect of modified Si Junzitang on tumor inhibition and growth of peripheral blood vessels in tumor-bearing mice was observed by tumorigenesis experiment in mice. Hematoxylin-eosin (HE) staining and immunohistochemistry (IHC) were used to detect the distribution of blood vessels and the expression of vascular endothelial markers (CD31) in tumor-bearing mice. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA expression levels of vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor 2 (VEGFR2) and tumor necrosis factor-α (TNF-α) in tumor tissue. Result:The inhibition rates of modified Sijunzi Tang in low-dose group (ig, 11.83 mg·kg-1·d-1), middle-dose group (ig, 23.66 mg·kg-1·d-1) and high-dose group (ig, 47.32 mg·kg-1·d-1) were 29.97%, 59.80%and 82.34%, respectively. Compared with the model group, the average tumor weight was lower in middle and high-dose groups, with statistically significant differences (PPPα in middle and high-dose modified Si Junzitang groups were lower than those in the model group (PConclusion:Modified Si Junzitang can inhibit the tumor growth of H22 tumor-bearing mice and the angiogenesis of transplanted tumors, which may be related to the reduction of TNF-α, VEGF and VEGFR2 expression levels.

RESUMO

Zeasesquiterpene A-E (1-5), five new sesquiterpenes with two cyclohexanes, were isolated from the roots of Zea mays. Their structures were elucidated on the basis of 1D and 2D NMR spectral data and ECD analysis. A plausible biosynthetic pathway for the compounds (1-6) were hypothesized. All isolated compounds were screened for cytotoxicities against five human cancer cell lines (A549, MDA-MB-231, SK-Hep-1, SNU638 and HCT116) in vitro by MTT assay. Compound 4 showed potential cytotoxic activities against A549 (14.3 µΜ) and SNU638 (9.7 µΜ). By contrast, compound 1 exhibited moderate cytotoxicity to the four human cancer cell lines (A549, SK-Hep-1, SUN638 and HCT116), and the IC50 values are from 19.5 µΜ to 22.5 µΜ.

RESUMO

Objective To explore the biological behavior and pathologic mechanism of ectopic decidua hemorrhage or acute postpartum hemorrhagic deciduosis caused by typical decidua tissue outside the uterine cavity under the influence of ovarian and placental hormones,and provide reference for accurate diagnosis and effective treatment. Methods From August 2017 to January 2018,there were 461 term-pregnant women undergoing ceasarian section in maternal and child health hospital of Qingbaijiang district,of whom 3 cases with ectopic deciduas were diagnosed.The clinical characteristics and microscopic features of 3 cases were retrospectively analyzed.The risk assessment to human health as well as effective control measures of ectopic deciduas were further elucidated along with the relevant references. Results Three patients with ectopic decidua generally had no obvious clinical symptoms or endometriosis,though dysmenorrheal and infertility might happen before pregnancy.Only an intraoperative incidentally finding of specific lesions varied from vacuolar plaques, hyperemia,vascular nodules, solid nodules and local hemorrhagic change.Under light microscope, the decidualized stroma revealed large polygonal cell aggregates, without nu-clear atypia.Due to the clinical features of abnormal angiogenesis and inflammatory reactions, ectopic decidua may cause severe cases such as acute postpartum hemorrhagic deciduosis,which could provide a basis for clinical comprehensive understanding and scientific prevention and treatment.Conclusion Ectopic decidua can happen in uterine seromuscular layers,ovary,great epiploon,cervix,vagina and so on,which is easy to be misdiagnosed or fails to be examined due to asymptom and nonspecific physical signs.It hasn’t been unequivocally clarified and widely recognized,nor earned extensively considered for rarely life-threatening haemorrhagic deciduosis in the prepartum and postpartum peri-od,which must be taken effective first-aid measures such as surgical intervention to protect maternal-fetal health.

RESUMO

Base on the transcriptome analysis and RT-PCR techniques,a pathogenesis-related protein 10 gene was isolated from Panax notoginseng root and named as PnPR10-2. Bioinformatics and phylogenetic trees analysis revealed that open reading frame (ORF) of PnPR10-2 was 465 bp in length,encoding 154 amino acids,containing one typical conserved domain of pathogenesis related protein Bet v I family, and showed high similarity with that from P. ginseng. The recombinant expressed plasmid pET32a(+)-PnPR10-2 was expressed in Escherichia coli BL21. The expression conditions were optimized and it could be expressed well in soluble and inclusion body protein. Purified PnPR10-2 recombinant protein from the supernatant of cells was used to analysis the pathogen resistance activity by paper method. The purified recombinant protein could inhibit typical root rot disease pathogen (Fusarium solani and Cylindrocarpon destructans)growth evidently, we conjecture that PnPR10-2 may participated in defense response of P. notoginseng resistance to root rot disease pathogen.

<p><b>OBJECTIVE</b>To explore the clinical efficacy and safety of lenalidomide plus low dose dexamethasone for treating patients with multiple myeloma (MM).</p><p><b>METHODS</b>A total of 19 MM patients were enrolled to receive the therapeutic schedule of lenalidomide plus dexamethasone in our hospital from May 2013 to June 2015. Lenalidomide 25 mg was taken orally daily for 21 days and resting for 7 days, and dexamethasone 10 mg was taken orally daily on the day 1-4, 7-10 and 13-16. The regimens were Rd (lenalidomide and dexamethasone, n = 12), and RCd (lenalidomide, ifosfamide and dexamethasone, n = 7).</p><p><b>RESULTS</b>Among 19 patients received 1 cycle of treatment 3 patients achieved complete remission (CR), 3 patients achieved very good partial remission (VGPR), 10 patients achieved partial remission (PR) and 3 patients in stable disease (SD) with an overall response rate (ORR = CR + VGPR + PR) of 84%; their ORR rate was 89% after 2 cycles of treatment. In the early stage of treatment, the renal function was improved in 4 out of 5 patients with renal dysfunction. And the common adverse reactions were hematologic toxicity in 4 patients, 1 degree rash in 5 patients, and gastrointestinal side effects in 4 patients.</p><p><b>CONCLUSION</b>The lenalidomide plus dexamethasone regimen has a good anti-multiple myeloma effect, which can control the disease rapidly and overcome the multidrug resistance in MM, improving the poor prognosis with renal dysfunction, and showing high remission rate in the patients exposed to bortezomib with low toxicity.</p>

RESUMO

This study was aimed to investigate the relation of reinfused hematopoietic stem cell volume and recipient's leukocyte count at reinfusion with prognosis of disease in allo-hematopoietic stem cell transplantation (allo-HSCT). The clinical data of 37 patients received allo-HSCT in our hospital were analyzed retrospectively. The 37 patients were divided into agranulocytosis and non-agranulocytosis groups according to the recipient's leukocyte count at reinfusion, and were divided into the high dose and low dose groups according to the median number of reinfused mononuclear cells (MNC) and CD34(+) cells. Then, hematopoietic reconstructions,GVHD, relapse and death rates of patients were compared. The results showed that the hematopoietic reconstruction of patients in non-agranulocytosis group and high dose MNC group were earlier than that in agranulocytosis group and low dose MNC group. There was no significant difference of hematopoietic reconstruction between the groups of high dose CD34(+) cells and low dose CD34(+) cells. The GVHD incidence was higher in high dose MNC group and non-agranulocytosis group than that in low dose MNC group and agranulocytosis group (P < 0.05). There were no statistical differences of relapsed and death rates between different reinfused number of HSC and recipient's leukocyte count at reinfusion.It is concluded that the infused MNC number and the recipient's leukocyte count at reinfusion in allo-HSCT correlated with hematopoietic reconstruction, the GVHD incidence is high in high dose MNC and non-agranulocytosis groups, the reinfused HSC volume and the recipient's leukocyte count at reinfusion not significantly relate with relapse and death rates.

RESUMO

<p><b>OBJECTIVE</b>To investigate the effect of maternal decabromodiphenyl ether (BDE-209) exposure on the sexual development in male offspring rats.</p><p><b>METHODS</b>Twenty-four pregnant Sprague-Dawley rats were randomly divided into three BDE-209 exposure groups and one control group. The three BDE-209 exposure groups were given BDE-209 (100, 300, and 900 mg/kg) by gavage on gestational days 12∼18, and the control group was given corn oil. The body weight and body length of each newborn male rat was measured at postnatal days 4, 10, 16, and 21. Twelve newborn male rats were randomly selected from each group; anogenital distance was measured at postnatal day 21, serum testosterone was measured, and the organ coefficient of testis was calculated.</p><p><b>RESULTS</b>The newborn male rats in all exposure groups showed declining trends in body weight and body length compared with those in the control group, and the 900 mg/kg BDE-209 exposure group had significantly lower body weight and body length than the control group at postnatal days 4, 10,16, and 21 (P < 0.01). At postnatal day 21, the 100, 300, and 900 mg/kg BDE-209 exposure groups had anogenital distances of 17.82±2.35 mm, 16.32±1.66 mm, and 15.80±1.34 mm, respectively, demonstrating a significant decrease with increased exposure dose (P < 0.05), but no significant difference was found when comparing these values with that of the control group (16.64±2.38 mm) (P > 0.05). There were no significant differences in serum testosterone and organ coefficients of testis and epididymis between the control group and BDE-209 exposure groups (P > 0.05).</p><p><b>CONCLUSION</b>Maternal exposure to BDE-209 has adverse effect on the growth of male offspring rats, but it leads to no significant changes in sexual development.</p>
