RESUMEN

OBJECTIVE: To conduct qualitative and quantitative analyses of Tripterygium hypoglaucum in Yinning Tablets, a compound preparation of traditional Chinese herbal medicine. METHODS: Thin-layer chromatography (TLC) was used for qualitative analysis of Tripterygium hypoglaucum in Yining Tablets and the analytical protocols were optimized. High-performance liquid chromatography (HPLC) was used to quantitatively analyze the content of triptolide (the main active ingredient of Tripterygium hypoglaucum) in Yinning Tablets. RESULTS: The results of TLC analysis showed that the test sample of Yinning Tablets and the positive control samples both produced clear, well separated spots without obvious interference in the blank samples. Assessment of the influences of the thin-layer plates from different manufacturers, temperature and humidity on the test results demonstrated good durability of the test. HPLC analysis of triptolide showed a good linear relationship within the concentration range of 1-100 µg/mL (regression equation: A=22.219C-19.165, r=0.9999); the contents of triptolide in 3 batches of Yinning tablets were 0.34, 0.34, and 0.28 µg per tablet, all within the range of 0.28-0.34 µg per tablet. It was finally determined that each Yinning tablet should not contain more than 0.6 µg of triptolide. CONCLUSION: TLC and HPLC are simple, accurate, durable and specific for qualitative and quantitative analyses of Tripterygium hypoglaucum in Yinning Tablets.

RESUMEN

The Asian ginseng root (Panax ginseng C.A. Meyer) is a very commonly used herbal medicine worldwide. Ginseng fruit, including the berry (or pulp) and seed, is also valuable for several health conditions including immunostimulation and cancer chemoprevention. In this study, the anticancer and anti-proliferative effects of the extracts of ginseng berry and seed were evaluated. The ginsenosides in the ginseng berry concentrate (GBC) and ginseng seed extract (GSE) were analyzed. We then evaluated their anti-colorectal cancer potentials, including antiproliferation, cell cycle arrest, and apoptotic induction. Further investigation consisted of the berry's adaptive immune responses, such as the actions on the differentiation of T helper cells Treg, Th1, and Th17. The major constituents in GBC were ginsenosides Re and Rd, which can be compared to those in the root. The GBC significantly inhibited colon cancer cell growth, and its anti-proliferative effect involved mechanisms including G2/M cell cycle arrest via upregulation of cyclin A and induction of apoptosis via regulation of apoptotic related gene expressions. GBC also downregulated the expressions of pro-inflammatory cytokine genes. For the adaptive immune responses, GBC did not influence Th1 and Treg cell differentiation but significantly inhibited Th17 cell differentiation and thus regulated the balance of Th17/Treg for adaptive immunity. Although no ginsenoside was detected in the GSE, interestingly, it obviously enhanced colon cancer cell proliferation with the underlined details to be determined. Our results suggested that GBC is a promising dietary supplement for cancer chemoprevention and immunomodulation.

RESUMEN

BACKGROUND: The loss of muscle mass, strength and function associated with increasing age has various health ramifications, including the elevated risk for falls, fractures, frailty, poor quality of life, and mortality. Several studies have confirmed the effects of protein supplementation and RT (resistance training) for this age-related change independently, but whether a combination of the two produces a stronger effect remains controversial. OBJECTIVE: This study aims to explore whether a combination of protein supplementation and RT leads to reduction of muscle mass, strength and function in the elderly. METHODS: We retrieved RCTs (randomized controlled trials) reporting the effects of protein supplementation combined with RT on muscle mass, strength and function in the elderly, published before May 2018 through PubMed, MEDLINE, Embase, and manual searches. RESULTS: Twenty-one RCTs were included, involving 1,249 participants. The results showed that protein supplementation combine with RT significantly enhances the muscle mass and strength of the older adults, where FFM (fat-free mass) increased by 0.23 kg (95% CI: 0.09, 0.38; P=0.002), ASMM (appendicular skeletal muscle mass) by 0.39 kg (95% CI: 0.14, 0.64; P=0.002), handgrip strength by 0.29 kg (95% CI: 0.08, 0.50; P=0.008), knee extension strength by 0.27 kg (95% CI: 0.06, 0.47; P=0.013), leg press strength by 0.33 kg (95% CI: 0.01, 0.64; P=0.04), but no significant effects were seen on muscle function. CONCLUSION: Compared to simple RT, protein supplementation combine with RT is more effective in enhancing the muscle mass and strength in the elderly, and the findings do not support the benefit of combination treatment for muscle function.

RESUMEN

Objective: To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on pain of patients in expansion process of skin soft tissue dilator on forehead by water injection. Methods: From June 2016 to June 2017, 100 patients in expansion process of skin soft tissue dilator on forehead by water injection meeting the inclusion criteria were admitted to Outpatient Department of Orthopedic Surgery of Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine. There were 43 men and 57 women among the patients, aged 27 to 55 years, and the prospective randomized controlled study was performed on them. The patients were divided into TEAS nursing group and routine nursing group according to the random number table, with 50 patients in each group. Patients in routine nursing group were performed with routine nursing in every water injection in outpatient department and 2 days later. On the basis of routine nursing, patients in TEAS nursing group were performed with TEAS treatment by responsible nurses in each water injection in outpatient department. The Shangxing, Diwei, and Hegu points were positioned accurately, and electrical stimulation was performed on the 3 points simultaneously by pulse acupuncture treatment instrument, with 30 minutes each time. Two days after every water injection of outpatient department, TEAS nursing was performed at home by patients and their family members under remote guidance of the responsible nurses, with 2 times each day and 30 minutes each time. Besides, follow-up was done by phone by the responsible nurses everyday. The nursing of patients in the 2 groups lasted the whole expansion process. After the expansion process, the overall pain degree and the most severe pain degree of patients during expansion process were scored by numerical rating scale, and the overall comfort degree and its dimensions of patients during expansion process were scored by the responsible nurses every day by simplified Comfort Status Scale. Data were processed with independent sample t test and chi-square test. Results: During expansion process, the overall pain score degree and the most severe pain degree score of patients in TEAS nursing group were (5.4±1.2) and (6.5±1.0) points, which were significantly lower than (6.1±1.3) and (7.5±1.4) points of patients in routine nursing group (t=-2.62, -4.00, P<0.05 or P<0.01). During expansion process, the physiological dimension, sociocultural dimension, psychological spirit dimension, environmental dimension, and total score of the overall comfort degree of patients in TEAS nursing group were (9.6±2.9), (20.1±2.8), (29.1±1.9), (22±3), and (80±6) points, significantly higher than (5.7±2.1), (16.8±2.8), (26.0±2.8), (21±4), and (69±8) points of patients in routine nursing group (t=8.03, 6.35, 7.60, 2.11, 10.64, P<0.05 or P<0.01). Conclusions: TEAS with appropriate intensity, frequency, and duration can alleviate the pain of patients during expansion process of skin soft tissue dilator on forehead by water injection and improve their comfort degree.

RESUMEN

This study represents the first report of a C-type lectin (ctl) in yellow catfish Tachysurus fulvidraco. The complete sequence of ctl complementary (c)DNA consisted of 685 nucleotides. The open reading frame potentially encoded a protein of 177 amino acids with a calculated molecular mass of c.y 20.204 kDa. The deduced amino-acid sequence contained a signal peptide and a single carbohydrate recognition domain with four cysteine residues and GlnProAsp (QPD) and TrpAsnAsp (WND) motifs. Ctl showed the highest identity (56.0%) to the predicted lactose binding lectin from channel catfish Ictalurus punctatus. Quantitative real-time (qrt)-PCR analysis showed that ctl messenger (m)RNA was constitutively expressed in all examined tissues in normal fish, with high expression in trunk kidney and head kidney, which was increased following Aeromonas hydrophila challenge in a duration-dependent manner. Purified recombinant Ctl (rCtl) from Escherichia coli BL21 was able to bind and agglutinate Gram-positive and Gram-negative bacteria in a calcium-dependent manner. These results suggested that Ctl might be a C-type lectin of T. fulvidraco involved in innate immune responses as receptors (PRR).

RESUMEN

Objective: To observe the effect of normal saline with intranasal corticosteroids in the treatment of allergic rhinitis(AR).Method:Two hundred and seventy-three outpatients with severe persistent allergic rhinitis were participated in this study.All patients were randomly divided into three groups, and were treated for 12 weeks using three different therapies, respectively. Symptom assessment of each patient were performed before treatment, 4 weeks, 8 weeks, and 12 weeks after treatment, respectively. The content of symptom assessment includes visual analogue scale, rhinoconjunctivitis quality of life questionnaire, symptoms scores and endoscopy examination scores.Result:Efficacy of intranasal corticosteroids combined with normal saline nasal irrigation in the treatment of AR is better than that of intranasal corticosteroids only, and is almost equivalent to intranasal corticosteroids combined with antihistamines.Conclusion:Long-term application of intranasal corticosteroids in combination with normal saline irrigation can effectively control and mitigate symptoms of severe persistent AR patients, and improve the patient's quality of life. This combination therapy is a better choice for the patient who is not satisfied with the single use of intranasal corticosteroids.

RESUMEN

OBJECTIVE: Whether or not acarbose benefits patients with polycystic ovary syndrome (PCOS) remains controversial. Therefore, we performed a meta-analysis to synthesize the literature regarding the therapeutic effects of acarbose on PCOS. METHODS: A comprehensive literature search was performed using terms, such as polycystic ovary syndrome, ovary polycystic disease, PCOS, hyperandrogenemia, acarbose, alpha-glucosidase inhibitors, and randomized controlled trials (RCTs), in the following bibliographic databases: Medline; Embase; and Cochrane Controlled Trials Register. The identified reference lists were checked manually. RESULTS: 6 RCTs met the inclusion criteria. Based on the meta-analysis of 3 studies, acarbose was superior to placebo or no treatment in reducing serum levels of testosterone (Std MD = - 3.38, 95% CI:-5.97~-0.78, P = 0.01) and acarbose caused a significantly higher incidence of side effects, such as abdominal distention and diarrhea (OR = 23.78, 95% CI: 5.67~99.75, P < 0.0001). The changes in Ferriman-Gallwey score or body mass index (BMI) were not significant. Based on the meta-analysis of 2 studies, acarbose were superior to placebo or no treatment in reducing triglycerides (TG; WMD = -18.18, 95% CI:-36.30~-0.06, P = 0.05) and very low-density lipoprotein (VLDL) cholesterol (WMD = - 6.49, 95% CI:-9.14~-3.84, P < 0.00001), and increasing high-density lipoprotein (HDL) cholesterol (WMD = 5.14, 95% CI:1.73~8.55, P = 0.003). There were no significant differences between acarbose and metformin with respect to improvements in ovulation rate, menstrual patterns, or changes in serum levels of testosterone, adverse events, or BMI. Heterogeneities were detected during the meta-analysis. CONCLUSIONS: This is the first meta-analysis to evaluate the role that acarbose plays in the treatment of PCOS. The currently available data showed that acarbose can reduce testosterone, TG, and VLDL, and increase HDL. Acarbose caused a significantly higher incidence of gastrointestinal disturbance. Given the small RCTs and poor quality of RCTs included, these results are not conclusive. A large-scale, randomized controlled study is needed to ascertain this uncertainty.

RESUMEN

In a previous in vitro study, the standardized turmeric extract, HSS-888, showed strong inhibition of Aß aggregation and secretion in vitro, indicating that HSS-888 might be therapeutically important. Therefore, in the present study, HSS-888 was evaluated in vivo using transgenic 'Alzheimer' mice (Tg2576) over-expressing Aß protein. Following a six-month prevention period where mice received extract HSS-888 (5mg/mouse/day), tetrahydrocurcumin (THC) or a control through ingestion of customized animal feed pellets (0.1% w/w treatment), HSS-888 significantly reduced brain levels of soluble (∼40%) and insoluble (∼20%) Aß as well as phosphorylated Tau protein (∼80%). In addition, primary cultures of microglia from these mice showed increased expression of the cytokines IL-4 and IL-2. In contrast, THC treatment only weakly reduced phosphorylated Tau protein and failed to significantly alter plaque burden and cytokine expression. The findings reveal that the optimized turmeric extract HSS-888 represents an important step in botanical based therapies for Alzheimer's disease by inhibiting or improving plaque burden, Tau phosphorylation, and microglial inflammation leading to neuronal toxicity.

RESUMEN

Inhibition of beta-amyloid (A beta) accumulation and A beta fibril (fA beta) formation from A beta are attractive therapeutic targets for the treatment of Alzheimer's disease (AD). While previous studies have shown anti-amyloidogenic effects of curcumin in vitro and in vivo, no studies have examined optimized turmeric extracts enriched in curcuminoids or turmerones. Three standardized turmeric extracts, HSS-838, HSS-848, and HSS-888, were prepared with different chemical profiles to investigate their potential therapeutic benefits for AD. These extracts were fingerprinted by DART TOF-MS to reveal the significant chemical complexity. In addition four curcuminoids (curcumin, tetrahydrocurcumin, demethoxycurcumin and bisdemethoxycurcumin) were also examined. We measured the effects of the extracts and curcuminoids, on the aggregation of A beta by using a thioflavin T cell-free assay and the secretion of A beta from human neuronal cells (SweAPP N2A cells) in vitro. All three extracts and the curcuminoids showed dose-dependent inhibition of fA beta aggregation from A beta(1-42) in the cell-free assay, with IC(50) values of

RESUMEN

OBJECTIVE: This study was designed to determine if repeated hyperbaric oxygen (HBO) exposure induces ischemic tolerance in focal cerebral ischemia. METHODS: Sixty male SD rats were used in this study. Thirty animals underwent transient middle cerebral artery occlusion (MCAO) and the other thirty permanent MCAO model. The rats were randomly allocated to 3 sub-groups: control group (n = 10), HBO-3 group (n = 10), and HBO-5 group (n = 10). The animals in HBO-3 and HBO-5 groups received 1 hour hyperbaric oxygenation at 2.5 atmosphere absolute (ATA) in 100% oxygen every day for 3 and 5 days, respectively. The animals in the control group received sham treatments. 24 hours after the last HBO, transient MCAO (120 min) and permanent MCAO were induced by introducing a 3-0 nylon monofilament suture through internal carotid artery based on the Koizumi technique. The neurological outcome was evaluated until 24 hours after reperfusion in transient MCAO rats and ischemia in permanent MCAO rats. The infarct volume was then assessed by TTC staining. RESULTS: In transient MCAO rats, the neurological outcome in both the HBO-3 and HBO-5 groups was better than that of the control group (P < 0.05 and 0.001). The infarct volume decreased from 171.5 +/- 113 mm3 to 40.6 +/- 49.9 mm3(P < 0.05) in the HBO-3 group and 16.2 +/- 28.8 mm3(P < 0.01) in the HBO-5 group. There were no significant differences in neurological outcome and infarct volume among the three groups in permanent MCAO rats. CONCLUSIONS: The present study demonstrated that HBO preconditioning can induce ischemic tolerance in transient not permanent MCAO rats in a "dose-dependent" manner.

RESUMEN

OBJECTIVE: To determine the preventive effect of the oil from the seed of Torreya grandis cv. merrillii (OTM) on experimental atherosclerosis in rats. METHODS: The concentration of blood lipids, plasma thromboxane (TXA2), prostacyclin (PGI2), the ratio of TXA2/PGI2 and endothelin (ET) were investigated in male Wistar rats fed high-fat feed (HFF) containing OTM(2%) for 12 weeks. RESULTS: OTM could reduce the level of serum total cholesterol (TC), triglyceride (TG) and the atherosclerosic index (AI), and increase the level of serum high-density-lipoprotein cholesterol (HDL-C). The plasma concentration of TXA2, ET and the ratio of TXA2/PGI2 in group supplemented with OTM were lower than those in HFF group. Moreover, the level of plasma PGI2, was higher than that in HFF group. CONCLUSION: OTM is beneficial in preventing atherosclerosis.

RESUMEN

BACKGROUND: Whether adjunctive tetracycline fibers can provide an additive effect to scaling and root planing in treating non-responsive sites in maintenance subjects is still controversial. Recolonization of the bacteria from untreated sites or from the extracrevicular region may explain the insignificant response to local therapy. The purpose of the present study was to evaluate the microbiological response of sites treated with tetracycline fibers combined with scaling and root planing. METHODS: The study was conducted in a split-mouth design. Thirty patients on maintenance therapy having at least 2 non-adjacent sites in separate quadrants with probing depths between 4 to 8 mm with bleeding on probing, or aspartate aminotransferase enzyme levels > 800 microIU in the gingival crevicular fluid, were treated with scaling and root planing plus tetracycline fibers or with scaling and root planing only. Subgingival plaque samples were collected at baseline, and 1, 3, and 6 months following treatment. A. actino-mycetemcomitans, C. rectus, B. forsythus, E. corrodens, F. nucleatum, P. gingivalis, and P. intermedia were detected by culture, immunofluorescence, or PCR technique. RESULTS: There was a reduction of total bacterial cell count, as well as of certain periodontal pathogens, following treatment. The prevalence of A. actinomycetemcomitans, B. forsythus, and P. gingivalis and the mean proportions of C. rectus, P. intermedia, F. nucleatum, and P. gingivalis decreased after therapy, but there was no statistically significant difference between the 2 treatment groups with respect to bacterial proportions or the number of positive sites. Besides, the pathogens could not be eliminated from the periodontal pocket, and recolonization of the pocket was noted at 3 months post-treatment. CONCLUSIONS: Bacteria located within the cheek, tongue mucosa, saliva, or untreated sites may contribute to reinfection of the pockets and explain the insignificant response to local tetracycline therapy.

RESUMEN

Experimental data indicated that Acanthopanax giraldii given intraperitoneally in mice had pronounced inhibitory effects on the CNS. It reduced the spontaneous activity, prolonged the hypnotic time of pentobarbital sodium and antagonised the amphetamine-induced hyperactivity. The results suggest that the sedative effect of A. giraldii is probably different from that of diazepam, but perhaps similar to that of reserpine.
