Abstract
BACKGROUND Tianhuang formula (THF) is a Chinese medicine prescription that is patented and clinically approved, and has been shown to improve energy metabolism, but the underlying mechanism remains poorly understood. The purpose of this study is to clarify the potential mechanisms of THF in the treatment of type 2 diabetes mellitus (T2DM). METHODS A murine model of T2DM was induced by high-fat diet (HFD) feeding combined with low-dose streptozocin (STZ) injections, and the diabetic mice were treated with THF by gavaging for consecutive 10 weeks. Fasting blood glucose (FBG), serum insulin, blood lipid, mitochondrial Ca2+ (mCa2+) levels and mitochondrial membrane potential (MMP), as well as ATP production were analyzed. The target genes and proteins expression of visceral adipose tissue (Vat) was tested by RT-PCR and western blot, respectively. The underlying mechanism of the regulating energy metabolism effect of THF was further explored in the insulin resistance model of 3T3-L1 adipocytes cultured with dexamethasone (DXM). RESULTS THF restored impaired glucose tolerance and insulin resistance in diabetic mice. Serum levels of lipids were significantly decreased, as well as fasting blood glucose and insulin in THF-treated mice. THF regulated mCa2+ uptake, increased MMP and ATP content in VAT. THF increased the mRNA and protein expression of AMPK, phosphorylated AMPK (p-AMPK), MICU1, sirtuin1 (SIRT1) and peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α). THF could increase the mCa2+ level of 3T3-L1 adipocytes and regulate mitochondrial function. The protein expression of AMPK, p-AMPK, mCa2+ uniporter (MCU) and MICU1 decreased upon adding AMPK inhibitor compound C to 3T3-L1 adipocytes and the protein expression of MCU and MICU1 decreased upon adding the MCU inhibitor ruthenium red. CONCLUSIONS These results demonstrated that THF ameliorated glucose and lipid metabolism disorders in T2DM mice through the improvement of AMPK/MICU1 pathway-dependent mitochondrial function in adipose tissue.

Abstract
OBJECTIVE Follicle-stimulating hormone (FSH) level changes may be another reason for increasing the risk of cardiovascular disease. In this study, we aimed to investigate the role of FSH in atherosclerosis and its underlying mechanism. METHODS ApoE-/- mice were divided into 4 groups, namely, the sham group, bilaterally orchidectomized group, FSH group, and testosterone-only group. Blood lipid and hormone levels were tested, aorta Oil Red O staining; the levels of NF-κB, Akt, eNOS, and FSH receptors in the aorta were measured by Western blotting. Expression of VCAM-1 was detected via Western blotting and immunohistochemical staining. Human umbilical vein endothelial cells (HUVECs) were used to induce endothelial injury model by adding FSH, and the levels of NF-κB, Akt, eNOS, and FSHR were tested in HUVECs. RESULTS FSH treatment exacerbated atherosclerotic lesions in ApoE-/- mice. Moreover, FSH could promote the expression of VCAM-1 protein in HUVECs, and this effect was possibly mediated by the activation of NF-κB, while NF-κB activation was further enhanced by the activation of the PI3K/Akt/eNOS pathway. FSH failed to activate Akt and NF-κB in the presence of the PI3K inhibitor LY294002 in HUVECs. CONCLUSION FSH promoted the development of atherosclerosis by increasing VCAM-1 protein expression via activating PI3K/Akt/NF-κB pathway.

Abstract
Angina pectoris (AP) with coronary heart disease (CHD) is one of the common cardiovascular diseases in clinical practice, which can be classified as "chest paralysis" in Chinese medicine according to its symptoms, and it is described in many ancient documents. Ancient Chinese medicine believes that the main pathogenesis of the disease is poor blood flow leading to paralysis of the heart and veins, so it is often treated by activating blood and removing blood stasis. In this study, 120 patients with AP of CHD of Qi stagnation and blood stasis type were randomly divided into the observation (n = 60) and the control group (n = 60). In the control group, basic care, conventional treatment, and unselected copper acupuncture scraping were used, while in the observation group, copper acupuncture scraping was performed at the right time of the heart meridian (11 : 00-13 : 00) on the basis of the control group, and all patients received the treatment for a total duration of 4 weeks. We collected data on the traditional Chinese medical (TCM) syndrome score, frequency and duration of angina attacks, nitroglycerin dosage, inflammatory factor levels, and hematological indices pretreatment and posttreatment in both groups. Patients' adverse effects during treatment were recorded, and the clinical efficacy and ECG efficacy in both groups were evaluated after 4 weeks. We used SPSS.20 statistical software to statistically analyze the above data, and the results showed that the clinical efficacy and ECG efficacy of the observation group were significantly higher than the control group posttreatment. After treatment, the TCM symptom score, angina attack frequency, attack duration and nitroglycerin dosage, serum interleukin-8 (IL-8), hypersensitive C-reactive protein (hs-CRP), and tumor necrosis factor-α (TNF-α) levels, whole blood viscosity (WBV), plasma viscosity (PV), fibrinogen (FIB), and hematocrit (Hct) were significantly lower in both groups compared with those posttreatment. And the observation group showed a greater decrease when compared with the control group. The results also showed that the overall incidence of adverse reactions was lower in both groups during the treatment period. The above results indicate that while ensuring high safety, the copper stone based on theory of midnight-noon ebb-flow can more effectively improve the symptoms and inflammatory response of the body and reduce the viscosity of the blood in AP with CHD of Qi stagnation and blood stasis, and it has better therapeutic effects.

Abstract
A colorimetric assay for human papillomavirus (HPV) DNA was developed based on the retardation of the avidin-induced aggregation of gold nanoparticles (AuNPs) by HPV DNA. Positively charged avidin acts as a coagulant for AuNP aggregation. In the presence of the target DNA, however, the aggregation of AuNPs is retarded owing to electrosteric stabilization as a result of the hybridization of the target and probe DNA. In the absence of HPV DNA, the stabilization effect caused by the biotinylated probe DNA is weak, resulting in NP aggregation and a color change from red to purple. Aggregation may be easily observed with bare eyes or spectrophotometrically at about 560 nm. The visual detection limit is 1 nM. The assay was used for the determination of HPV DNA after polymerase chain reaction (PCR) amplification without any further purification. Graphical abstract Schematic presentation of the avidin-induced aggregation of unmodified gold nanoparticles (AuNPs) which leads to a color change from red to purple. In the presence of dsDNA, however, the aggregation is remarkably retarded.

Abstract
BACKGROUND The role and phenotypic alterations of intrahepatic natural killer (NK) cells in liver disease were investigated. Although intrahepatic NK cells reportedly functionally deteriorate in the fibrotic liver, it remains unclear how the clinical severity of liver disease affects intrahepatic NK cells in patients with advanced liver failure. METHODS We analyzed the phenotypic properties of intrahepatic NK cells by using mononuclear cells extracted from ex vivo liver perfusate effluents from patients who underwent liver transplantation. The relationship between the clinical severity of liver disease and the phenotype of intrahepatic NK cells in these patients was also evaluated. To estimate the immunological responsiveness of intrahepatic NK cells, phenotypic enhancement after interleukin-2 stimulation was analyzed. RESULTS Intrahepatic NK cells from patients with advanced liver failure exhibited down-regulated monomodal expression of NKp46, a major activating molecule. Notably, the expression level of NKp46 decreased depending on the severity of liver disease, Model for End-Stage Liver Disease score, and Child-Pugh score rather than the etiology. After in vitro recombinant interleukin-2 stimulation, the enhancement of expression of cytotoxic molecules, NKp44, and tumor necrosis factor-related apoptosis-inducing ligand was significantly impaired in intrahepatic NK cells from patients with liver failure, concurrently with decreased expression of CD122 and interleukin-2 receptor beta. CONCLUSIONS Our results suggest that terminal deterioration of liver environments by chronic liver disease impairs the potential of local NK cells, depending on the severity of the deterioration. These influences of advanced liver failure on intrahepatic NK cells may be attributed to multicentric carcinogenesis in patients with liver failure.

Abstract
OBJECTIVE To study the distribution of HPV16 E6 gene mutations and p53 codon72 polymorphism among women with HPV16+ cervical precancerous lesions and explore their relationship with the risk of cervical intraepithelial neoplasia (CIN) 2, 3. Materials and Meth- ods: This study analyzed a total of 112 cases of exfoliated HPV16+ cervical cell specimens which were divided into group I (normal and CIN1, 55 cases) and group2 (CIN2, 3, 57 cases). Among the 112 specimens, 85 cases were successfully amplified for HPV E6 gene by PCR and the PCR products were sequenced directly. P53 codon72 region was also amplified from the 112 specimens and the PCR products were sequenced directly and compared with the standard sequence. RESULTS Among the 85 amplified HPV sequences, point mutations such as T178G, T350G, G132A, A442C, T310G, G94T, C551A, etc. were found, among which, T178G showed the highest rate (51.76%). The rate of HPV16 E6 mutation T178G in CIN2, 3 group was significantly higher than that in normal and CINI group, i.e., in the 112 amplified p53 codon72 sequences, the distribution of Pro/Pro genotype in normal, and CIN1 group was significantly different from that in CIN2, 3 groups, and the disease risk of Pro/Pro genotype was much higher than that of Arg/Arg and Arg/Pro genotypes. CONCLUSION HPV16 E6 T178G mutation increases the disease risk of CIN2, 3. Meanwhile, compared with Arg/Arg and Arg/Pro genotypes, p53 codon72 Pro/Pro genotype more associated with the disease risk of CIN2, 3.

Abstract
A novel fluorescent chemosensor bearing a rhodamine and a dansyl moiety was developed for highly selective detection of Fe(3+) based on fluorescence resonance energy transfer (FRET) mechanism. Binding of Fe(3+) to the chemosensor induced spirolactam ring opening in the rhodamine moiety and subsequent off-on FRET from the dansyl energy donor to the rhodamine energy acceptor due to the spectral overlap between the emission of the dansyl moiety and the absorption of the ring opened rhodamine moiety. Job's plot analysis indicated a 1:1 binding stoichiometry between the chemosensor and Fe(3+). The association constant was estimated to be 2.72×10(3) M(-1) according to the Benesi-Hildebrand method. With the feature of easy synthesis, simple structural skeleton and excellent sensing ability, the newly synthesized chemosensor provided the potential for applying as a highly selective fluorescent probe in complex samples containing various competitive metal ions and developing other metal ion chemosensors to fulfill various needs of biological and environmental field.

Abstract
Analyses of data from the representative 2002 National Nutrition and Health Survey were used to assess the likelihood of metabolic complications of overweight and obesity in Chinese children aged 7-17 years. Chinese criteria for body mass index classification were used for overweight and obesity with the 75th percentile US adolescent values for waist circumferences and all the metabolic criteria for blood pressure, lipids, fasting glucose established for US adolescents. Diabetes in 7-12-year-olds was 0.2% and 0.4% in children aged 12-18 years. Prevalences of dyslipidaemia (61.9%), hypertriglyceridaemia (18.2%) and low high-density lipoprotein cholesterol (56.1%) were high and 16.0% of 15-18 years had hypertension. The overall prevalence of the metabolic syndrome was 3.3% with more than half the children having at least one metabolic abnormality and 19.8% having at least two. All the metabolic parameters were significantly elevated in the overweight and obese children except high-density lipoprotein cholesterol. These data emphasize the marked sensitivity of Chinese children to the metabolic complications of overweight and obesity and amplify the need for early preventive measures.

Abstract
Since national figures on the occurrence of metabolic syndrome among Chinese adolescents are lacking, this study aims to estimate its prevalence and distribution among Chinese youngsters. The 2002 China National Nutrition and Health Survey is a nationally representative cross-sectional study. Applying the criteria for US adolescents, we estimated the prevalence of metabolic syndrome among 2761 adolescents aged 15 to 19 years. The prevalence of metabolic syndrome among Chinese adolescents overall was 3.7 % (10 % in US adolescents). It was 35.2 %, 23.4 % and 2.3 % among adolescents who were overweight (BMI > or = 95th percentile), at risk of overweight (BMI between 85th and 95th percentile) and normal weight (BMI below the 85th percentile), respectively. Urban boys had the highest rate (5.8 %) compared with girls and rural youngsters. Among adolescents who had a BMI > or = 85th percentile and one or two parent(s) with metabolic syndrome, the prevalence was 46.4 %. A total of 96 % of overweight adolescents had at least one and 74.1 % overweight adolescents had at least two abnormalities of metabolic syndrome. Based on these figures, it is estimated that more than three million Chinese adolescents have metabolic syndrome. Both overweight and metabolic syndrome prevalence among adolescents are still relatively low in China, but the prevalence of metabolic syndrome among Chinese overweight adolescents is similar to those living in the USA.

Abstract
Selecting appropriate evaluation indicators for surveying and monitoring iodine nutritional status is needed. The indicators, which are used commonly in recent literature, are urinary iodine, thyroid volume, dietary iodine intake, thyroid function parameters and intelligence quotient. These indicators are summarized on their clinical significance, application range, expression method and so on. The purpose of this review is to provide some scientific references for people who are working on prevention and treatment of iodine deficiency disorders.

Abstract
Male weaning rats were divided randomly into five groups. They were fed with diets containing zinc deficient(DZ), high zinc(HZ), normal zinc (NZ) and high zinc pair-fed with zinc deficient group(HZP) respectively. The rats in DZ and HZ groups were exchanged diets after 20 days. A part of rats in each group were killed at days 20, 50 and 70. The activities of alkaline phosphatase(ALP), 5'-nucleotidase(5'-NT) and copper-zinc-superoxidase dismutase(Cu-Zn-SOD), the zinc concentration in plasma and kidney were determined to assess the better indices for zinc nutrition. The results indicted that: The activities of ALP in DZ group at 20 d was significantly lower than that in the same group at the beginning, in the HZ group and in the HZP group, and increased significantly after the diet was changed to HZ diet after 30 days. The activities of 5'-NT in DZ group rats was decreasing with the extension of experimental period. These results indicated that the activities of ALP and 5'-NT were sensitive to zinc supplementation even though they were changed a little during zinc exhausted. The activity of ALP was decreasing with growing, and the activity of 5'-NT was increased with growing. Zinc concentration in plasma of DZ group was significantly lower than that of other groups which include DZ-HZ group at the 50th day, and it was also the lowest among groups at the end of experiment. Zinc concentration in the kidney of HZ-DZ group was significantly lower than that of HZ and DZ-HZ groups by the end of experiment. There were little changes of the activity of Cu-Zn SOD and the zinc content in kidney during the experiment period. These results indicated that the activities of both ALP and 5'-NT and plasma zinc were sensitive to zinc supplementacior and zinc deficiency.

Abstract
Male weanling Wistar rats were fed with either a basal selenium deficient diet (a Torula yeast based semisynthetic diet, containing Se 0.01 mg/kg) or a selenium sufficient diet supplemented with Se as Na2SeO3 (containing Se 0.5 mg/kg). Rats were killed after different weeks(0,1,2,4,8,12,15,17,19,20 and 24 respectively). Their organs were taken to observe the kinetic change of selenium concentration, the activities of intracellular glutathione peroxidase (cGPX), extracellular glutathione peroxidase (eGPX), and phospholipid hydroperoxide glutathione peroxidase (PHGPX) in different organs. The results showed that selenium levels and the activities of selenoenzyme in testis and pituitary were more resistant to selenium deficiency than other organs. During selenium deficiency, the utilization of selenium by PHGPX and deiodinase was prior to eGPX and cGPX, which suggested that the function of PHGPX and deiodinase were more important than that of eGPX and cGPX.
