[Efficacy of medicinal penetration on acupoint as adjunctive therapy on histiocytic necrotizing lymphadenitis of heat-toxin syndrome: a randomized controlled trial].

OBJECTIVE: To evaluate the clinical efficacy of medicinal penetration on acupoint combined with medication for histiocytic necrotizing lymphadenitis (HNL) of heat-toxin syndrome, and to explore the methods of improving the clinical effect. METHODS: A total of 72 cases with HNL with heat-toxin syndrome were randomly divided into an observation group and a control group, 36 cases in each group. The patients in the control group were treated with oral administration of prednisone tablets for 40 days (first 5 days: 10 mg, three times a day; since then, reduced by 5 mg every 7 days). In the observation group, on the basis of the medication in the control group, the patients were treated with acupoint application and ultrasonic drug penetration therapy, once a day for 14 days. The acupoints of Waiguan (TE 5), Fengchi (GB 20) of affected side and ashi points were selected. The changes of target lymph node swelling, visual analogue score (VAS), axillary temperature and total score of symptoms and signs were evaluated before treatment and 7, 14, 28 and 40 d into treatment; the changes of white blood cell (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and lactic dehydrogenase (LDH) were evaluated on 14 d and 40 d into treatment; the patients were followed-up for half a year. RESULTS: ① Fourteen days into treatment, the clinical cured rate in the observation group was 38.9% (14/36), which was superior to 16.7% (6/36) in the control group (P<0.01); the clinical cured rates were both 100% in the two groups on 40 d into treatment. ② The VAS score, axillary temperature and the total score 7 d into treatment, as well as node swelling, VAS score, axillary temperature and the total score 14, 28 and 40 d into treatment in the two groups were significantly improved (P<0.01); the total score and VAS score of 7 d into treatment, target lymph node swelling, VAS score and total score of 14 d into treatment in the observation group were significantly improved than those in the control group (P<0.01). ③ Compared before treatment, WBC, CRP, ESR in the two groups were significantly improved 14 d and 40 d into treatment (P<0.01), and LDH in the two groups were decreased 40 d into treatment (P<0.01), but there was no significant difference between the two groups (P>0.05). ④ The recurrence rate in the observation group was 5.6% (2/36), which was similar to 16.7% (6/36) in the control group (P>0.05). CONCLUSION: The medicinal penetration on acupoint as adjunctive treatment could effectively relieve the discomfort symptoms of HNL patients with syndrome of heat and toxin, improve the clinical cured rate, and provide the research direction for shortening the course of medication.

Effects of Rock Climbing Exercise on Physical Fitness among College Students: A Review Article and Meta-analysis.

BACKGROUND: The aim of this study was to systematically determine the effects of rock climbing on College Students' physical fitness by means of Meta-analysis. METHODS: Studies investigated the possible fitness benefits of rock climbing were identified through a computerized search of six electronic databases: China National Knowledge Infrastructure, China Science Periodical Database, PubMed, Web of Science, SPORTDiscus and PsycINFO. Effects of rock climbing exercise intervention trials ≥4 wk, published in English and Chinese between Jan 1996 and May 2016, including between subject and within subject designs, were reviewed. Nine studies were included in this meta-analysis. Ten selected variables in this meta-analysis were: Body fat percentage, VO2max, Heart rate, Handgrip strength, Lower limb pedaling power, Vertical Jump, Push-Ups, Pull-Ups, Sit-Ups, and Sit-and-reach. The effect sizes of these ten variables were calculated (P<0.05) and forest plots along with effective sizes were presented. RESULTS: Rock climbing can significantly improve Handgrip strength, Lower limb pedaling power, Vertical Jump, Push-Ups, Pull-Ups, Sit-Ups and Sit-and-reach (P<0.01), and significantly increase VO2max (P<0.05), however, rock climbing did not show significant improvement on Heart rate and Body fat percentage. CONCLUSION: As a newly popular physical exercise, rock climbing has a significantly positive impact on the physical fitness among college students. Rock climbing may be more effective if the college students engage in it for a longer term.

Serum resistin positively correlates with serum lipids, but not with insulin resistance, in first-degree relatives of type-2 diabetes patients: an observational study in China.

To investigate whether serum resistin correlated with hypertension, obesity, dyslipidemia, or insulin resistance (IR) in Chinese type 2 diabetes mellitus (T2DM) patients and their first-degree relatives (DFDRs) in a case-control observational study.We determined the serum levels of resistin, plasma lipids, glucose, and insulin, and performed clinical assessments of hypertension, obesity, and IR for 42 T2DM patients, 74 of their DFDRs, and 51 healthy control participants with no family history of T2DM (NC group). The biochemical and clinical variables were compared between the 3 groups, and relationships between serum resistin and the other variables were evaluated using a Pearson correlation analysis.Significant trends were observed in the triglyceride, HbA1c, and resistin levels, in which the values observed in the DFDR group were intermediate to those of the T2DM and NC groups (P < .05 for all). A stratified analysis revealed significant trends in the resistin level and scores for homeostasis model assessment (HOMA) indexes for IR and insulin sensitivity in women and in the HbA1c and resistin levels in men (P < .05 for all), with DFDR subjects exhibiting intermediate values. The Pearson analysis showed that serum resistin positively correlated with total cholesterol and low-density lipoprotein cholesterol in the DFDR group only (P < .05 for both), and that resistin did not correlate significantly with HOMA indexes, blood glucose, insulin, HbA1c, triglyceride, high-density lipoprotein cholesterol, BMI, waist or hip circumference, or blood pressure.Our results suggest that elevated serum resistin might contribute to an increased risk of hyperlipidemia in DFDRs of Chinese T2DM patients.

Pan-PIM kinase inhibition provides a novel therapy for treating hematologic cancers.

PURPOSE: PIM kinases have been shown to act as oncogenes in mice, with each family member being able to drive progression of hematologic cancers. Consistent with this, we found that PIMs are highly expressed in human hematologic cancers and show that each isoform has a distinct expression pattern among disease subtypes. This suggests that inhibitors of all three PIMs would be effective in treating multiple hematologic malignancies. EXPERIMENTAL DESIGN: Pan-PIM inhibitors have proven difficult to develop because PIM2 has a low Km for ATP and, thus, requires a very potent inhibitor to effectively block the kinase activity at the ATP levels in cells. We developed a potent and specific pan-PIM inhibitor, LGB321, which is active on PIM2 in the cellular context. RESULTS: LGB321 is active on PIM2-dependent multiple myeloma cell lines, where it inhibits proliferation, mTOR-C1 signaling and phosphorylation of BAD. Broad cancer cell line profiling of LGB321 demonstrates limited activity in cell lines derived from solid tumors. In contrast, significant activity in cell lines derived from diverse hematological lineages was observed, including acute lymphoblastic leukemia (ALL), acute myelogenous leukemia (AML), multiple myeloma and non-Hodgkin lymphoma (NHL). Furthermore, we demonstrate LGB321 activity in the KG-1 AML xenograft model, in which modulation of pharmacodynamics markers is predictive of efficacy. Finally, we demonstrate that LGB321 synergizes with cytarabine in this model. CONCLUSIONS: We have developed a potent and selective pan-PIM inhibitor with single-agent antiproliferative activity and show that it synergizes with cytarabine in an AML xenograft model. Our results strongly support the development of Pan-PIM inhibitors to treat hematologic malignancies.

Pim2 is required for maintaining multiple myeloma cell growth through modulating TSC2 phosphorylation.

Multiple myeloma (MM) is the second most common hematologic malignancy. Despite recent treatment advances, it remains incurable. Here, we report that Pim2 kinase expression is highly elevated in MM cells and demonstrate that it is required for MM cell proliferation. Functional interference of Pim2 activity either by short hairpin RNAs or by a potent and selective small-molecule inhibitor leads to significant inhibition of MM cell proliferation. Pim inhibition results in a significant decrease of mammalian target of rapamycin C1 (mTOR-C1) activity, which is critical for cell proliferation. We identify TSC2, a negative regulator of mTOR-C1, as a novel Pim2 substrate and show that Pim2 directly phosphorylates TSC2 on Ser-1798 and relieves the suppression of TSC2 on mTOR-C1. These findings support Pim2 as a promising therapeutic target for MM and define a novel Pim2-TSC2-mTOR-C1 pathway that drives MM proliferation.

[Analgesic effect of sinomenine on SSNI model rats and monoamine neurotransmitters in striatal extracellular fluid].

OBJECTIVE: To observe the analgesic effect of sinomenine on the neuropathic pain rat model induced by SSNI, and discuss its impact on monoamine neurotransmitters in striatal extracellular fluid. METHOD: Male SD rats were randomly divided into the sham operation group, the SSNI model group, the gabapentin group (100 mg x kg(-1)), the sinomenine high dose group (40 mg x kg(-1)) and the sinomenine low dose group (20 mg x kg(-1)). Mechanical hyperalgesia and cold pain sensitivity were evaluated by Von Frey hairs and cold spray. Striatum was sampled by microdialysis. High performance liquid chromatography-electrochemical detector (HPLC-ECD) were used to detect the content of such neurotransmitters as monoamine neurotransmitters noradrenaline (NE), dopamine (DA), 5-hydroxy tryptamine (5-HT) and their metabolites dihydroxyphenylacetic phenylacetic acid (DOPAC) and 5-hydroxyindoleacetic acid (5-HIAA). RESULT: SSNI model rats showed significant improvement in mechanical withdrawal threshold and cold pain sensitivity, significant decrease in intracerebral NE and notable increase in DA, 5-HT and their metabolites. Compared with the model group, the sinomenine high dose group showed significant increase in mechanical withdrawal threshold at 60, 90, 180 and 240 min after abdominal administration (P < 0.01), significant decrease in cold pain sensitivity score during 30-240 min (P < 0.05). Sinomenine can significantly up-regulated NE content in striatal extracellular fluid during 45-135 min (P < 0.05), remarkably reduce DA content and DOPAC at 45, 75 and 135 min (P < 0.05), 5-HT content during 45-135 min, DOPAC during 75-165 min (P < 0.05), and 5-HIAA during 45-135 min (P < 0.05). CONCLUSION: Sinomenine has the intervention effect on neuropathic pain in SSNI model rats. Its mechanism may be related to disorder of monoamine neurotransmitters in striatal extracellular fluid.

Effect of Erzhi Pill (二至丸) on improving cerebral nerve cell apoptosis in aging rats.

OBJECTIVE: To investigate the effects of Erzhi Pill (二至丸,EZP) on nerve cell apoptosis in senescence model rats. METHODS: The rats model of senescence was established by peritoneal D-galactose injection combined with thymusectomy. Forty SD rats were randomized into four groups, the normal control group, the senescence model group, the EZP treated group, and the vitamins treated group, 10 in each group. The rats were made into senescence model except those in the normal group. In the same time of D-galactose injection, the rats were treated respectively with distilled water, EZP 4.32 g/kg, and vitamins E and C 0.06 g/kg daily for 6 weeks via intragastric infusion. The index of main viscera (as brain, testis, etc.), serum levels of superoxide dismutase (SOD) activity, and total anti-oxidation capacity (T-AOC) were measured after a 6-week treatment. Meanwhile, the cerebral cortex neuronal apoptosis proportion and mitochondrial membrane potential (MMP) were detected by flow cytometry. RESULTS: Both EZP and vitamins E and C treatments showed effects on increasing testis index and serum level of T-AOC, reducing the percentage of neuronal apoptosis in the cerebral cortex, and elevating MMP in the aging rats model. CONCLUSIONS: EZP could inhibit the cerebral cortex neuron apoptosis and maintain the mitochondrial function in the senescent process of rats induced by peritoneal D-galactose injection combined with thymusectomy. It also shows antioxidation effect to some extents.

[Effects of apolipoprotein A1 and B gene polymorphism on avascular necrosis of the femoral head in Chinese population].

OBJECTIVE: To investigate the effects of Apo A1 and B gene polymorphism on avascular necrosis of the femoral head (ANFH) in north Chinese Han population. METHODS: Polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) technique was used in samples of 143 cases with documented ANFH and 92 healthy control matched by age and sex individuals selected from north Chinese Han nationality. The studied loci include promoter region (-75bp) and the intron 1 (+83 bp) of Apo A1 gene, Eco RI,Xba I of Apo B gene; polymerase chain reaction was used to study 3'-VNTR of Apo B gene. RESULTS: At -75 bp in promoter, the frequency of A/A genotype in ANFH group was significantly higher than that in control group (P < 0.01), while the frequency of G/A genotype in ANFH group was significantly lower than that in control group (P < 0.01). No difference was found in the frequency of genotype at +83bp in intron 1 of Apo A1 gene, Eco RI, Xba I and 3'-VNTR loci of Apo B gene. CONCLUSION: Apolipoprotein A1 gene A/A substitution at position -75 in promotor is associated with ANFH, the mutation may be one of the sensitive genes of ANFH, first reported inside and abroad. But no evident relationship was found between gene polymorphism of +75 bp loci of Apo A1 gene, Eco RI loci of Apo B gene, Xba I loci of Apo B gene or 3'-VNTR of Apo B gene and ANFH.

[Relationship between plasma protein expression profiles and states of Zang-Fu organs in patients with phlegm or blood stagnation syndromes due to hyperlipidemia and atherosclerosis].

OBJECTIVE: To investigate the relationship between the plasma biomarker proteins and the states of Zang-Fu organs in patients with phlegm or blood stagnation syndromes due to hyperlipidemia and atherosclerosis. METHODS: The states of Zang-Fu organs in 146 patients with hyperlipidemia and atherosclerosis were diagnosed by syndrome differentiation of traditional Chinese medicine. The plasma proteins from these patients were separated by two-dimensional polyacrylamide gel electrophoresis (2-DE). Differential protein profiling was established by Image Master 6.0 software, and the differential proteins were analyzed by quadrupole time of flight mass spectrometry (Q-TOF-MS). The association between the plasma biomarker proteins and the states of Zang-Fu organs was analyzed by graphical models. RESULTS: The biomarker proteins such as fibrinogen gamma chain, albumin and apolipoprotein AI (precursor) in discrimination of the patients with phlegm syndrome from phlegm accumulating with stagnation syndrome were correlated with the deficiency of kidney-qi, heart-qi and spleen-qi. Among the four biomarker proteins in discrimination of the patients with phlegm syndrome from blood stagnation syndrome, albumin, adrenomedullin binding protein (precursor) and haptoglobin (precursor) were correlated with the deficiency of kidney-qi and heart-qi, but complement component C4 was independent of the deficient Zang-Fu organs. The biomarker albumin was associated with the deficiency of kidney-qi, heart-qi and spleen-qi, and adrenomedullin binding protein (precursor) was correlated with the deficiency of spleen-qi in discrimination of the patients with blood stagnation syndrome from phlegm accumulating with stagnation syndrome. As the potential biomarker proteins in discrimination of the patients with non-phlegm and non-stagnation syndrome from phlegm accumulating with stagnation syndrome, the fibrinogen beta chain was related with the deficiency of kidney-qi, and apolipoprotein AI (precursor) was correlated with both the deficiency of kidney-qi and heart-qi. CONCLUSION: There exists inherent correlation between the states of Zang-Fu organs and the plasma probable biomarker proteins in the patients with different phlegm or blood stagnation syndromes due to hyperlipidemia and atherosclerosis.

[Study on relationship between polymorphism of apolipoprotein E gene and syndromes of phlegm and blood stasis in patients with coronary heart disease].

OBJECTIVE: To explore the relationship between polymorphism of apolipoprotein E (ApoE) exon 4 gene and different syndromes in patients with coronary heart disease (CHD). METHODS: Two hundred patients with CHD were divided into four groups according to syndrome differentiation, including syndrome of phlegm (PS), syndrome of blood stasis (BSS), syndrome of phlegm-blood stasis blocking (PBBS) and syndrome of non-phlegm and non-blood stasis (NPNBS). One hundred healthy volunteers were included in control group. Blood lipids were measured by routine examination. Total DNA of peripheral blood was extracted. ApoE genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. All data were analyzed by SAS software. RESULTS: (1)The occurrence rate of epsilon4 allele of ApoE in patients with CHD was 19.5%, significantly higher than 9.5% in the control group (P<0.05), and the E 3/4 genotype was especially more frequent (P<0.01). (2) The levels of total cholesterol (TC), total triglycerides (TG) and low-density lipoprotein cholesterol (LDL-C) in patients with epsilon4 were higher than those in patients without epsilon4 (P<0.01). (3) The frequencies of epsilon4 allele and E3/4 genotype in patients with PS were significantly higher than those in patients with BSS (P<0.05). CONCLUSION: ApoE epsilon4 allele, especially E3/4 genotype, is the risk factor of CHD. There is a relatively close relationship between patients with ApoE epsilon4 allele and PS. It may be one of the main susceptible genes in CHD patients with PS.

[Complete Freund's adjuvant-induced splenic T cell apoptosis in the prevention of diabetes in non-obese diabetic mice].

OBJECTIVE: To study the apoptosis of T lymphocytes in the spleen and its role in complete Freund's adjuvant (CFA) preventing diabetes in non-obese diabetic (NOD) mice. METHODS: Forty-two NOD mice were divided into two groups randomly: CFA-treated NOD female mice (6w, 12w and 30w) and PBS-treated NOD female mice (6w, 12w and 30w). The apoptosis of splenic T lymphocytes was observed with the TDT-mediated fluorescein-dUTP nick-end labelling (TUNEL) technique and avidin-biotin complex method. RESULTS: CFA induced the apoptosis of CD4+ T lymphocytes in the mouse spleen and could prevent the development of Type 1 diabetes (T1DM) in NOD female mice. CONCLUSION: CFA preventing Type 1 diabetes in NOD mice may be related to the apoptosis of T lymphocytes in the spleen, which downregulates mature CD4+ T lymphocytes in the periphery.
