RESUMEN
OBJECTIVE: To explore the expression of Exosome Component 4ï¼EXOSC4ï¼ in the tissues of newly diagnosed patients with diffuse large B-cell lymphoma (DLBCL) and its clinical significance. METHODS: The expression of EXOSC4 protein in the tissues of 181 newly diagnosed DLBCL patients was analyzed by immunohistochemical staining. Clinical data were collected. The correlation between EXOSC4 protein expression in the tissues of newly diagnosed DLBCL patients and clinical features were analyzed and its prognostic significance. RESULTS: The positive rate of EXOSC4 protein expression was 68.51% in the tissues of 181 newly diagnosed DLBCL patients. These patients were divided into two groups, with 44 cases in high expression group and 137 cases in low expression group. There were no significant differences in age, gender, B symptoms, serum lactate dehydrogenase (LDH) level, Eastern Cooperative Oncology Group (ECOG) score, Ann Arbor stage, extranodal disease, International Prognostic Index (IPI) score, National Comprehensive Cancer Network IPI (NCCN-IPI) score, and cell origin between the two groups (P>0.05). Cox multivariate regression analysis showed that high EXOSC4 protein expression in tissues was an independent poor prognostic factor for OS and PFS in newly diagnosed DLBCL patients (all P<0.05). K-M survival analysis showed that newly diagnosed DLBCL patients with high EXOSC4 protein expression had significantly shorter overall survival (OS) and progression free survival (PFS) than those patients with low EXOSC4 protein expression (all P<0.05). CONCLUSION: High EXOSC4 protein expression in tissues of newly diagnosed DLBCL patients is an independent poor prognostic factor for survival.

BACKGROUND: With the development of cancer precision medicine, a huge amount of high-dimensional cancer information has rapidly accumulated regarding gene alterations, diseases, therapeutic interventions and various annotations. The information is highly fragmented across multiple different sources, making it highly challenging to effectively utilize and exchange the information. Therefore, it is essential to create a resource platform containing well-aggregated, carefully mined, and easily accessible data for effective knowledge sharing. METHODS: In this study, we have developed "Consensus Cancer Core" (Tri©DB), a new integrative cancer precision medicine knowledgebase and reporting system by mining and harmonizing multifaceted cancer data sources, and presenting them in a centralized platform with enhanced functionalities for accessibility, annotation and analysis. RESULTS: The knowledgebase provides the currently most comprehensive information on cancer precision medicine covering more than 40 annotation entities, many of which are novel and have never been explored previously. Tri©DB offers several unique features: (i) harmonizing the cancer-related information from more than 30 data sources into one integrative platform for easy access; (ii) utilizing a variety of data analysis and graphical tools for enhanced user interaction with the high-dimensional data; (iii) containing a newly developed reporting system for automated annotation and therapy matching for external patient genomic data. Benchmark test indicated that Tri©DB is able to annotate 46% more treatments than two officially recognized resources, oncoKB and MCG. Tri©DB was further shown to have achieved 94.9% concordance with administered treatments in a real clinical trial. CONCLUSIONS: The novel features and rich functionalities of the new platform will facilitate full access to cancer precision medicine data in one single platform and accommodate the needs of a broad range of researchers not only in translational medicine, but also in basic biomedical research. We believe that it will help to promote knowledge sharing in cancer precision medicine. Tri©DB is freely available at www.biomeddb.org , and is hosted on a cutting-edge technology architecture supporting all major browsers and mobile handsets.

OBJECTIVE: To observe the effect of acupuncture combined with medication on the pregnancy outcome of kidney deficiency and blood stasis type recurrent implantation failure (RIF) in prethrombotic infertility patients. METHODS: A total of 70 RIF patients of kidney deficiency and blood stasis type who were to undergo freeze-thaw embryo transplantation were randomly divided into control and treatment groups, with 35 cases in each group. Patients in the control group were given the basic treatment of artificial periodic freeze-thaw embryo transfer and oral aspirin enteric-coated tablet, 25 mg each time, twice a day, for 3 consecutive menstrual cycles. Patients in the treatment group were treated with acupuncture on the basis of the control group, 30 min each time, 3 times a week, for 3 consecutive menstrual cycles. The clinical pregnancy rate, embryo implantation rate and live birth rate of the two groups were compared. Before treatment and 1 day before transplantation, the scores of kidney deficiency and blood stasis symptom were compared. The blood flow pulse index (PI) and resistance index (RI) of the uterus spiral artery were detected by Doppler ultrasound before treatment and 1 day before transplantation. The endometrial thickness was detected 1 day before transplantation. The contents of plasma D-dimer, serum homocysteine (Hcy) and serum thromboxane B2 (TXB2) were detected. RESULTS: The clinical pregnancy rate, embryo implantation rate and live birth rate in the treatment group were higher than those in the control group (P<0.05). After treatment, the scores of kidney deficiency and blood stasis symptom, the levels of plasma D-dimer, serum Hcy and TXB2, the PI and RI value in both groups were decreased (P<0.05) compared with those before treatment, and the indexes in the treatment group were decreased (P<0.05) more than those in the control group. There was no significant difference in endometrial thickness between the two groups. In the course of treatments, 7 patients in the control group underwent gastric distension pain, poor appetite, constipation, nausea and other gastrointestinal reactions, while only 2 patients in the treatment group had the above discomfort reactions. CONCLUSION: On the basis of medication, acupuncture can reduce the serum TXB2 content in RIF patients in prethrombotic state, improve vascular endothelial function, enhance endometrial tolerance, alleviate the symptoms of kidney deficiency and blood stasis, reduce drug adverse reactions, and ultimately improve the pregnancy outcome and increase the rate of embryo implantation.

OBJECTIVE: To observe the effects of auricular thumbtack needle on breast feeding and lactation function in primiparous women with cesarean section, and to explore its mechanism of action from the perspective of lactation-related gene expression. METHODS: One hundred cases of primiparous women with cesarean section were randomly divided into an observation group (50 cases, 3 cases dropped off) and a control group (50 cases, 2 cases were eliminated). The patients in the control group were treated with routine obstetric care. Based on the treatment of the control group, the patients in the observation group were treated with auricular thumbtack needle at Neifenmi (CO18), Xiong (AH10), Xiongzhui (AH11), Shenmen (TF4), and Jiaogan (AH6a), etc., with one side of auricular point selected, only once for a total of 3 d. The lactation initiation time, lactation adequacy rate at postpartum 72 h, exclusive breastfeeding rate at postpartum 42 d, and breastfeeding score after treatment were compared between the two groups. Real-time quantitative PCR and Western blot method were used to detect the mRNA and protein expression levels of TDP-43, Btn1A1 and XDH. RESULTS: After treatment, the lactation initiation time in the observation group was earlier than that in the control group (P<0.01), and breastfeeding score in the observation group was higher than that in the control group (P<0.01). The lactation adequacy rate at postpartum 72 h was 63.8% (30/47) in the observation group, which was higher than 41.7% (20/48) in the control group (P<0.05). The exclusive breastfeeding rate at postpartum 42 d was 72.3% (34/47) in the observation group, which was higher than 47.9% (23/48) in the control group (P<0.05). The mRNA and protein expression levels of TDP-43 and Btn1A1 in breast milk in the observation group were higher than those in the control group (P<0.01), while there was no statistically significant difference in mRNA and protein expression of XDH in breast milk between the two groups (P>0.05). CONCLUSION: The auricular thumbtack needle in addition to routine care could promote lactation initiation, improve lactation adequacy rate and exclusive breastfeeding rate in primiparous women with cesarean section, and the action mechanism may be related to up-regulation of TDP-43 and Btn1A1 expression.

Tea is consumed widely around the world owing to its refreshing taste and potential health benefits. However, drinking tea is considered a major route for dietary aluminum exposure in areas where tea consumption is relatively large. To assess the health risk associated with drinking tea, the contamination level of aluminum was determined in 81 tea samples. The transfer rate of aluminum during tea brewing was investigated. Then based on the site-specific exposure parameters such as consumption data and body weight for six different subpopulations in Fujian, the exposure risks were estimated using a probabilistic approach. Results demonstrate that the contents of aluminum in green tea, white tea, oolong tea, and black tea were significantly different according to the one-way ANOVA analysis (p < 0.05). The transfer rate of aluminum were 32.6%, 31.6%, 26.3%, and 14% for white tea, black tea, oolong tea, and green tea, respectively. With respect to the oral reference dose, the exposure of inhabitants in Fujian to aluminum through drinking tea is under control (even at the 99th percentile).

Perchlorate is known as a thyroid disrupter. Its contamination in various tea samples was monitored, and 286 samples belonging to four types of tea leaves were analysed. The detection rate of perchlorate in tea was 99.3%. The mean concentration in different tea types decreased in order from green tea, oolong tea, white tea to black tea. A probabilistic approach was performed to evaluate the dietary exposure of perchlorate for six different subpopulations. The daily intakes (EDIs) for consumers over the age of 41 were higher than that of other subpopulations. The hazard quotient for six groups was lower than 1 even at the extreme percentile (P99). It indicates that the risk of dietary exposure to perchlorate from tea consumption for Fujian people is acceptable without considering other foodstuffs. However, the high occurrence of perchlorate in tea samples suggested that the actual source of this contaminant should be further investigated.

The objective of this study was to evaluate the residues of 42 pesticides subject to public concern in Tieguanyin tea produced in Fujian, China. The presence of 42 pesticide residues in 90 Tieguanyin tea samples were determined. A total of 17 pesticides were detected. At least one pesticide residue was detected in 65 samples (72.2%). The detected pesticides imidacloprid, tolfenpyrad, bifenthrin, acetamiprid were found in 55.6%, 33.3%, 18.9% and 16.7% of samples, respectively. Pesticide residues in Tieguanyin tea varied significantly over the seasons and across the production regions. Based on data obtained, the health risks associated with long-term exposure to those pesticides were assessed and risks of detected pesticides were ranked. The hazard quotients (HQs) among the detected pesticides range from 5 × 10-8 for fenpropathrin to 3 × 10-4 for imidacloprid. The results demonstrated that despite a high occurrence of pesticide residues in Tieguanyin tea, residue levels observed could not be considered as a serious public health problem. The risk ranking scheme showed dicofol and thiacloprid were considered to pose a medium-risk. The suggestions for 17 detected pesticides used in Tieguanyin tea plantation were made, including those already banned from use in China (dicofol and methomyl), recommended for diminished use (thiacloprid and chlorpyrifos), and permitted use with considering the pre-harvest interval (13 other pesticides).

White tea has been of increasing public interest worldwide owing to its health benefits. Based on 2 years of surveillance, the long-term and cumulative chronic exposure risks of pesticide residues through white tea drinking were assessed for different subpopulations in Fujian, China. Twenty-five different pesticides were found, and 74.8% of samples contained at least one pesticide residue. The most frequently detected pesticide was bifenthrin with detection rates of 61.6%. Risk assessment was performed using both the deterministic approach and semiprobabilistic model under the best-case and the worst-case scenarios. The results demonstrated that the dietary risks were extremely low for six different subpopulations in which the risks for adults over the age of 41 were relatively higher. The risk ranking scheme indicated that isocarbophos and triazophos were considered to be of medium risk. The different use suggestions for the 25 positive pesticides are proposed to further minimize the exposure risk to consumer health. PRACTICAL APPLICATION: Tea is the second most popular nonalcoholic beverage throughout the world. Pesticides are used to improve the yield of tea. Pesticide residues in tea could be one of the exposure pathways for consumers. Monitoring residual levels and assessing the health risk assessment in tea are thus in an urge.

OBJECTIVE: To observe the effect of acupuncture on vascular endothelial function in patients of polycystic ovary syndrome (PCOS) with impaired glucose tolerance (IGT) and normal glucose tolerance (NGT). METHODS: A total of 140 patients with PCOS were divided into an IGT group (70 cases, 11 dropped off) and a NGT group (70 cases, 9 cases dropped off). The patients in the two groups were treated with full-cycle acupuncture at Zhongwan (CV 12), Guanyuan (CV 4), Qihai (CV 6), Tianshu (ST 25), etc. once every other day, 3 times a week, for 3 months. Before and after treatment, TCM symptom score, insulin resistance index [including fasting plasma glucose (FPG), 2-hour blood glucose (2hPG), fasting serum insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR)] and vascular endothelial related factors [including asymmetric dimethylarginine (ADMD), endothelin-1 (ET-1), malondialdehyde (MDA), nitric oxide (NO)] were compared between the two groups; in addition, the obese subgroup and non-obese subgroup of the two groups were further compared. RESULTS: Compared before treatment, the TCM symptom scores, ADMD, ET-1 and MDA after treatment were decreased (P<0.05), and NO was increased (P<0.05) in the two groups; FPG, 2hPG, FINS and HOMA-IR after treatment were decreased in the IGT group (P<0.05), the improvement of the above indexes in the IGT group was more significant than that in the NGT group (P<0.05). After treatment, the serum levels of ADMD, ET-1 and MDA were decreased (P<0.05), and NO was increased (P<0.05) in the obese subgroup. In the IGT group, the improvement of serum ADMD, ET-1, MDA and NO in the obese subgroup was more significant than that in the non-obese subgroup (P<0.05). In the NGT group, the improvement of ET-1, MDA and NO in the obese subgroup was more significant than that in the non-obese subgroup (P<0.05). CONCLUSION: Acupuncture could improve vascular endothelial function in PCOS patients, IGT patients have better efficacy than NGT patients, and obese patients have better efficacy than non-obese patients.

Objective: Lycopodiastrum casuarinoides, a fern of the Lycopodiaceae family, is a traditional Chinese medicine, which has similar efficacy to that of Huperzia serrata in treating rheumatoid arthritis (RA). However, they are different in the contents and compositions of lycopodium alkaloids. In this study, the biosynthesis related genes of lycopodium alkaloids and genetic markers are discovered in L. casuarinoides transcriptome. Methods: The plant of L. casuarinoides was collected and was subjected to the RNA isolation, cDNA library construction, high throughput RNA sequencing and bioinformatics analysis. Results: Totally 124, 524 high-quality unigenes were assembled from RNA sequencing reads, with an average sequence length of 601 bp. Among the L. casuarinoides transcripts, 61,304 shared the significant similarity (E-value < 10-5) with existing protein sequences in the public databases. From 124,524 unigenes, 47,538 open reading frames (ORFs) were predicted. Based on the bioinformatics analysis, all possible enzyme genes involved in the lycodine-type alkaloids biosynthetic pathway of L. casuarinoides were identified, including lysine decarboxylase (LDC), primary amine oxidase (PAO), malonyl-CoA decarboxylase, etc. Sixty-four putative cytochrome p450 (CYP) and 827 putative transcription factors were selected from the transcriptome unigenes as the candidates of lycodine-type alkaloids biosynthesis modifiers. Furthermore, 13,352 simple sequence repeats (SSRs) were identified from 124,524 unigenes, of which dinucleotide motifs AG/CT were the most abundant (50.1%). Meanwhile, we confirmed the amplification effectiveness of 25 PCR primer pairs for randomly selected SSRs. Conclusion: We obtained the comprehensive transcriptomic information from the high throughput RNA sequencing and bioinformatics analysis, which provided a valuable resource of transcript sequences of L. casuarinoides in public databases.
RESUMEN
OBJECTIVE: To compare the clinical effect of the combined treatment of acupuncture, moxibustion, Chinese herbal medicine and western medication and simple western medication on polycystic ovary syndrome (PCOS) of kidney deficiency and blood stagnation pattern and explore the effect on endometrial receptivity and the expression of serum homeobox gene A10 (HOXA10). METHODS: A total of 60 patients with PCOS of kidney deficiency and blood stagnation pattern were randomized into a combined treatment group and a western medication group, 30 cases in each one. In the western medication group, on the fifth day of menstruation, clomiphene citrate tablets were taken orally, 50 mg each time, once daily, consecutively for 5 days. On the day when the follicle diameter was ≥ 18 mm, chorionic gonadotrophin for muscular injection, a dose of 10 000 U was given. Before sleep, the aspirin enteric-coated tablets were taken orally, 50 mg (except during menstruation). In the combined treatment group, on the base of the treatment as the western medication group, acupuncture and moxibustion were adopted and the Chinese herbal for tonifying the kidney and activating blood circulation was taken orally. The acupoints were Guanyuan (CV 4), Qihai (CV 6), Zusanli (ST 36), Sanyinjiao (SP 6), Zigong (EX-CA 1), etc. Acupuncture was remained for 30 min each time, once every two days and discontinued during menstruation. Chinese herbal was given from the 3rd day of menstruation till the onset of the next menstruation, one dose each day. After consecutive treatment for 3 menstrual cycles in the two groups, the real-time polymerase chain reaction (RT-PCR) method was adopted to determine the expression of serum HOXA10 before and after treatment in the patients of the two groups. The endometrial thickness at ovulatory phase, uterine arterial flow 7 days after ovulation [including uterine arterial pulsatility index (PI), resistance index (RI), peak systolic velocity (PSV)/end diastolic velocity (EDV), meaning S/D], pregnancy rate and the score of Chinese medicine symptoms before and after treatment were compared in the patients between the two groups. RESULTS: â After treatment, the expression of serum HOXA10 was higher than that before treatment in the patients of the two groups (P<0.01). The increase range in the combined treatment group was larger than the western medication group (P<0.01). â¡ After treatment, the endometrial thickness at the ovulatory phase was increased in the patients of the two groups (P<0.01). The increase range of the endometrial thickness in the combined treatment group was larger than the western medication group (P<0.01). ⢠The pregnancy rate was 46.7% (14/30) in the combined treatment group, higher than 26.7% (8/30) in the western medication group (P<0.05). ⣠After treatment, the bilateral uterine arterial PI, RI and S/D values, as well as TCM symptom score were all lower than those before treatment in the patients of the two groups (P<0.01). The decrease range of each index in the combined treatment group was greater than the western medication group (P<0.01, P<0.05). CONCLUSION: The combined treatment with acupuncture, moxibustion and medication effectively improves endometrial receptivity and uterine arterial flow in the patients with PCOS of kidney deficiency and blood stagnation pattern and increases pregnancy rate. The therapeutic effect is better than the simple western medication and its mechanism is probably related to the regulation of serum HOXA10 expression.

Objective:To evaluate the efficacy of acupuncture-drug balanced anesthesia in improving the outcomes following radical correction of tetralogy of Fallot (TOF) under cardiopulmonary bypass (CPB) in the pediatric patients.Methods:A total of 100 pediatric patients, aged 3-8 yr, weighing 9-24 kg, with American Society of Anesthesiologists physical status Ⅱ or Ⅲ, scheduled for elective radical correction of TOF with CPB, were divided into 2 groups ( n=50 each) using a random number table method: acupuncture-drug balanced anesthesia group (group ADBA) and conventional anesthesia group (group CA). In group ADBA, transcutaneous acupoint electrical stimulation (disperse-dense wave, frequency 2/100 Hz, current intensity 6 mA, pulse width 0.2-0.6 ms) of Baihui (GV20) and bilateral acupoints of Neiguan (PC6), Hegu (LI4), and Ximen (PC4) acupoints was performed after induction of general anesthesia and maintained until the end of surgery.In group CA, the children received combined intravenous-inhalational anesthesia, and electrodes were only applied on the same acupoints without electrical stimulation.Venous blood samples were collected for blood routine examination and for determination of the concentrations of interleukin-6 (IL-6), IL-8 and tumor necrosis factor-alpha(TNF-α) at 30 min before surgery (T 1), 30 min after the start of surgery (T 2) and 1 h and 1, 2, 3 and 5 days after surgery (T 3-7). The length of hospital stay and development of postoperative major adverse events were recorded. Results:Compared with group CA, the plasma concentrations of IL-6, IL-8 and TNF-α at T 2-7 and white blood cell count, neutrophil count and neutrophil percentage at T 4-7 were significantly decreased, postoperative length of hospital stay was shortened ( P<0.05), and the incidence of acute lung injury was decreased obviously in group ADBA ( P<0.05). Conclusion:Acupuncture-drug balanced anesthesia can improve the outcomes following radical correction of TOF under CPB to a certain extent, and the mechanism is related to inhibiting inflammatory responses in pediatric patients.
RESUMEN
The aim of current study was to assess the effects of Baduanjin exercise on cerebrovascular function, cardiac structure and cardiac function, static pulmonary function, traditional risk factors of CVD and the related psychological outcomes in older community adults at risk for ischaemic stroke. A randomized controlled trial was conducted in three community between November 2013 and October 2015. Older community-dwelling adults (N = 170) were randomly allocated into either a Baduanjin training (5 × 60 min/weekly) or control group who kept their unaltered lifestyle during a 12-week intervention period. Primary (cerebral haemodynamic parameters) and secondary outcomes (cardiac structure, cardiac function, static pulmonary function, traditional risk factors and the related psychological outcomes) were measured at baseline, after a 12-week intervention period and after an additional 12-week follow-up period. After the 12-week intervention period and additional 12-week follow-up period, the Baduanjin exercise group displayed significant changes in most cerebral haemodynamic parameters compared to the control group: lower systolic blood pressure, diastolic blood pressure, plasma total cholesterol levels, waist circumference, hip circumference and waist/hip ratio; and improved mood, self-confidence, self-esteem, quality of life and sleep quality. A supervised 12-week Baduanjin exercise intervention was effective and safe in modulating cerebral haemodynamics, reducing blood pressure and improving anthropometric parameters and related psychological outcomes in older community adults at risk for ischaemic stroke.

OBJECTIVE: Based on the emotional theory of Traditional Chinese Medicine, and combined with the modern medicine theory of psychological stress, a research model of human uterine leiomyoma cells (ULM) was cultured in vitro to determine the effectiveness of adrenergic receptor (AR) agonists in human ULM cell growth. In addition, we studied the functional influence of "liver depression and psychological stress theory" on fibroid formation by intervening in the AR-cAMP-PKA signaling pathway. The intention was to establish a new method to prevent and cure fibroids through "liver depression and psychological stress theory" and provide an experimental basis for the Traditional Chinese Medicine emotional theory. MATERIALS AND METHODS: Primary human ULM cells were enriched by collagenase digestion. Immunohistochemistry and hematoxylin and eosin (HE) staining were used for cytological identification. Using this model, we studied intervention using specific AR agonists on ULM cells to observe the influence of "liver depression and psychological stress theory" on estrogen receptor (ER), progesterone receptor (PR), vascular endothelial growth factor (VEGF) and fibroblast growth factors (FGF). RESULTS: Norepinephrine (NE) and epinephrine (E) are adrenergic receptor agonists. They promoted ULM cell proliferation and increased the levels of ER, PR, VEGF and FGF. In contrast, isoproterenol (ISO) inhibited ULM cell proliferation and decreased the levels of ER, PR, VEGF and FGF. The protein expression of cAMP and PKA in ULM cells was reduced and the levels of ER, PR, VEGF and FGF were increased when co-treatment with the α-AR blocker (phentolamine). The ß-AR blocker (metoprolol) displayed an opposite effect. CONCLUSIONS: AR agonists modulated ER, PR, VEGF and FGF levels in ULM cells in an AR-cAMP-PKA-dependent signaling pathways to influence fibroid occurrence and development.

Pepper, a daily-used seasoning for promoting appetite, is widely used in folk medicine for treating gastrointestinal diseases. Piperine is the major alkaloid in pepper and possesses a wide range of pharmacological activities. However, the mechanism for linking metabolic and medicinal activities of piperine remains unknown. Here we report that piperine robustly boosts mTORC1 activity by recruiting more system L1 amino acid transporter (SLC7A5/SLC3A2) to the cell membrane, thus promoting amino acid metabolism. Piperine-induced increase of mTORC1 activity in resident peritoneal macrophages (pMΦs) is correlated with enhanced production of IL-6 and TNF-α upon LPS stimulation. Such an enhancement of cytokine production could be abrogated by inhibitors of the mTOR signaling pathway, indicating mTOR's action in this process. Moreover, piperine treatment protected resident pMΦs from bacterium-induced apoptosis and disappearance, and increased their bacterial phagocytic ability. Consequently, piperine administration conferred mice resistance against bacterial infection and even sepsis. Our data highlight that piperine has the capacity to metabolically reprogram peritoneal resident macrophages to fortify their innate functions against bacterial infection.

Background. Baduanjin is a traditional Chinese qigong that has been practiced for a long time in China as a mind-body exercise in community elderly populations. The objective of this study was to qualitatively evaluate the perceived benefit of regular Baduanjin qigong in community elders. Methods. A total of 20 participants who had completed the 12-week Baduanjin qigong training were interviewed regarding their perceived effect on physical and psychological health and whether Baduanjin qigong was suitable for the elderly. Results. Almost all participants agreed that Baduanjin qigong could promote their multisystem or organ functions (e.g., digestive and circulatory systems), increase their immunity, make their bodies relax, and improve their mood and confidence. Most of the participants also agreed that Baduanjin qigong was appropriate for elderly individuals. Few individuals felt bored because of an hour Baduanjin training each day. Conclusions. The findings suggest that regular Baduanjin qigong may be potentially helpful to promote the overall physical and psychological health of elderly community populations and may be useful and feasible as a body-mind exercise in the health promotion in the elderly community populations.
RESUMEN
BACKGROUND: The physical and mental health of college students tends to continuously decline around the world, therefore, it is important to improve their health during college period. Baduanjin, a traditional Chinese exercise which combines movements with breath and mind, may be one of the selectable effective exercises. However, the effect of Baduanjin exercise on college students has not been established. In this study, we systematically assessed the effectiveness and safety of Baduanjin exercise on physical and mental health of college students by a rigorous randomized, parallel-controlled design. METHODS: A total of 222 college students from Fujian University of Traditional Chinese Medicine were recruited and randomly allocated at an equal ratio into control or Baduanjin training. Participants in control group were informed to maintain their original activity habit, and those in Baduanjin exercise group received a 12-week Baduanjin exercise training with a frequency of 1 hour per day and 5 days per week on the basis of their original activity habit. The physical and psychological outcomes, including lumbar muscle strength, lower limb proprioception function, physical fitness, as well as self-reported symptom intensity, stress, self-esteem, mood, quality of life, quality of sleep, and adverse events, were evaluated at baseline, 13 weeks (at the end of 12-week intervention), and 25 weeks (after the 12-week follow-up period). Intention-to-treat analysis was performed for the above outcomes. RESULTS: Compared with controls, significant improvements in Baduanjin exercise group at the end of 12-week intervention period were found on lower limb proprioception function (the rate of average trace error on right lower limb (%): control 23.50±5.50, Baduanjin 21.92±6.54, P=0.004; the rate of average trace error on left lower limb (%): control 22.32±6.62, Baduanjin 20.63±4.62, P=0.046), cardiorespiratory endurance (step test index: control 47.66±5.94, Baduanjin 50.07±9.30, P=0.025), flexibility (control 14.35±7.26cm, Baduanjin 15.39±6.43cm, P=0.009) and explosive force of lower limb (standing long jump test (m): control 1.77±0.24, Baduanjin 1.79±0.22, P=0.005 for adjustment baseline) in physical outcomes, and attention (Schulte Grid test (second): control 210.4±51.15, Baduanjin 192.4±47.14, P=0.034) in mental outcome. Lumbar muscle strength in Baduanjin group had been moderately enhanced but no significant difference compared to controls. No significant changes in other physical and mental outcomes, including vital capacity, blood pressure, heart rate, hand grip force, self-symptom intensity, stress, self-efficacy, quality of life, and quality of sleep, were found between groups. No adverse event was reported during the study period. CONCLUSION: Regular Baduanjin exercise had an advantage for college students on improvement of lower limb proprioception, enhance of cardiorespiratory endurance, flexibility, explosive force of lower limb and attention, compared with usual exercise.

BACKGROUND: The reduced production of thyroid hormones is the main feature of the clinical state termed hypothyroidism. In Chinese philosophical and medical theory, it results from Yang deficiency. Chinese herbal medicines (CHM) are thought to restore Yang and have been used in China to treat hypothyroidism for many years. OBJECTIVES: To assess the effects of CHM for hypothyroidism. SEARCH METHODS: We searched The Cochrane Library, MEDLINE, EMBASE, the Chinese Biomedical Literature Database on Disc, and the China National Knowledge Infrastructure for randomised clinical trials (RCTs). The date of the last search was September 2014 for all databases. We also searched for ongoing trials in trial registers. SELECTION CRITERIA: We considered RCTs of CHM alone or combined with thyroid hormone therapy compared with no treatment, placebo or thyroid hormone therapy. We also planned to compare different formulae of CHM with each other, alone or combined with thyroid hormone therapy. Hypothyroid individuals had to be diagnosed by the standard criteria valid at the time of the beginning of the trial regardless of the cause of hypothyroidism. DATA COLLECTION AND ANALYSIS: Data extraction and risk of bias assessment were not performed because no study could be included. MAIN RESULTS: We found no RCTs and therefore could not establish the effects of CHM on hypothyroidism. AUTHORS' CONCLUSIONS: Currently, there is no evidence available from RCTs on CHM for the treatment of hypothyroidism. We also did not find any ongoing registered trial.

It has been claimed that consumptions of Abrus cantoniensis (AC) and Abrus mollis (AM) as folk beverages and soups are good to cleanse liver toxicants and prevent liver diseases. There is scant information on the phytochemical profiles and antioxidant activities of these two varieties. Five major phytochemicals in these two cultivars were qualitatively and quantitatively compared using UPLC-PDA. A high level of total phenolic content (TPC) and total flavonoid content (TFC) was found in AC and AM. AC, in general, showed some antioxidant activities comparable to that of BHT, and stronger radical scavenging activities and higher reducing power than that of AM (p<0.05). When principal component analysis (PCA) was applied, high correlation between TPC, TFC and their antioxidant activities was found. Hence, this study proved that, both AC and AM could serve as antioxidant-rich component in foods or beverages to promote health function.

<p><b>OBJECTIVE</b>To compare the difference in the clinical efficacy on cervical spondylosis of vertebral artery type (CSA) treated with thermosensitive moxibustion at different dosages.</p><p><b>METHODS</b>Sixty cases of CSA were randomized into a saturated moxa dosage group and a regular moxa dosage group, 30 cases in each one. The thermosensitive moxibustion was adopted in the two groups. The mild suspended moxibustion was applied at two acupoints with the strongest thermosensitization. In the saturated moxa dosage group, the moxibustion time was determined by the disappearance of thermosensitization. In the regular moxa dosage group, 15 min was required on each acupoint. The treatment was given twice a day for first 4 days in the two groups. Since the 5th day, the treatment was given once a day, continuously for 10 times, and totally 14 days were required. The score of symptoms and function and clinical efficacy were compared between the two groups before and after treatment as well as 6-month follow-up after treatment.</p><p><b>RESULTS</b>The curative and effective rate was 56.7% (17/30) after treatment and 60.0% (18/30) in 6-month follow-up after treatment in the saturated moxa dosage group, which were superior to 26.7% (8/30) and 30.0% (9/30) in the regular moxa dosage group respectively (P < 0.01, P < 0.05). The scores of clinical symptoms and function after treatment and in follow-up were improved apparently as compared with those before treatment in both groups (all P < 0.01). The scores of clinical symptoms and function after treatment and in follow-up in the saturated moxa dosage group were increased much more apparently than those in the regular moxa dosage group (after treatment: 22.32 +/- 4.64 vs 17.43 +/- 3.21; in follow-up: 23.01 +/- 4.76 vs 18.32 +/- 2.13, both P < 0.01).</p><p><b>CONCLUSION</b>The thermosensitization moxibustion of saturated dosage achieves the superior short-term and long-term efficacies in the treatment of CSA as compared with the regular moxibustion dosage.</p>
