SW872 preadipocytes were cultured and induced to differentiate by oleic acid in vitro.The levels of adiponectin and its receptors (AdipoR1 and AdipoR2) mRNA were measured by semiquantitative RT- PCR.The concentration of adiponectin in the culture medium was assayed by ELISA.The results showed that rhIL- 6 could inhibit adiponectin,AdipoR1 mRNA expressions and adiponectin secretion in SW872 adipocytes in a time- and dose-dependent manner,but did not influence adipoR2 mRNA expression.

Objective To examine the possibility that a candidate causal species of the skin and lung tumor promotion induced by exposure to dimethylarsinic acid(DMAv)and dimethylarsinous acid(DMAⅢ),caused by the induction of oxidative stress in mice.Methods Two stages lung tumotigensis animal model induced by lung tumor initiator(4-nitroquinoline 1-oxide,4NQO)and promoter(DMAv)in ddY mice,was used to examine the effect of(-)epigallocatechin gallate(EGCG)on DMAv promoting lung tumorigenesis.Two stages skin tumorigenesis animal model induced by skin tumor initiator[dimethylbenz(α)anthracene,DMBA]and promoter(DMAⅢ)in hairless mice.was used to examine the effects of DMAⅢ in skin tumorigenesis and histopathology.The goxo-2'-deoxyguanosine (8-oxodG)in lung and epidermis were analyzed by HPLC.Results The incidence of lung tumors and 8-oxodG level of lung tissue decreased significantly in 4NQO+DMAv+EGCG group.compared with 4NQO+DMAv group (0.89±0.30 vs 4.00±0.82,1.21±0.09 vs 1.53±0.32,P＜0.01).The incidence of severe keratosis in DMBA+ DMIⅢ group was more than that in DMBA group(25 vs 10,P＜0.05).An significant elevation of 8-oxodG in epidermis was observed in 0.5 h[(1.67±0.17)/105 dG],1.0 h[(1.62±012)/105 dG],2.0 h[(1.66±023)/105dG], 3.0 h[(1.60±0.15)/105 dG],compared with 0 h[(1.25±0.11)/105 dG],being significant(P＜0.05).Conclusion tumor promotion due to DMAv administration is mediated by DMAⅢ through the induction of oxidative stress.

OBJECTIVETo observe the clinical efficacy difference between segmentation scraping and conventional acupuncture for cervical spondylosis (CS) so as to provide effective treatment method.

METHODSEighty-five cases of cervical type of CS were randomly divided into a scraping group (44 cases) and an acupuncture group (41 cases). The segmentation scraping therapy was used in the scraping group. The scraping group was treated with focusing on scraping the head and joint part of neck and occiput in the upper cervical spine injury, and focusing on scraping the lower section of cervical and shoulder in the lower cervical spine injury, once every seven days, totally for 3 times. In the acupuncture group, Fengchi (GB 20),Wangu (TE 5), Tianzhu (BL 10),Neck-Jiaji (EX-B 2), etc. were selected,once daily,for 15 days. The visual analogue scale (VAS) was used to evaluate the immediate analgesic effect after the first treatment and the clinical efficacy was observed after the end of treatment.

RESULTSAfter the first treatment, the score of VAS was decreased significantly in the scaping group (P < 0.01), but there was no significant difference in the acupuncture group compared with those before treatment (P > 0.05); the score of VAS in the scaping group after the first treatment was lower than that in the acupuncture group (3.66 +/- 0.74 vs 5.43 +/- 0.35, P < 0.01). Compared with before treatment, the scores of VAS were decreased significantly after treatment in two groups (both P < 0.01), but without significant difference between two groups (P > 0.05); the effective rate was 95.5% (42/44) in the scaping group and 87.8% (36/41) in the acupuncture group, the curative effects were similar (P > 0.05).

CONCLUSIONBoth of scraping and acupuncture therapies have good analgesic effect for cervical spondylosis, and overall effects are similar, but the immediate analgesic effect of scraping thrapy is better than that of conventional acupuncture.

White spot lesions (WSLs), due to enamel demineralization, occur frequently in orthodontic treatment. We recently developed a novel rechargeable dental composite containing nanoparticles of amorphous calcium phosphate (NACP) with long-term calcium (Ca) and phosphate (P) ion release and caries-inhibiting capability. The objectives of this study were to develop the first NACP-rechargeable orthodontic cement and investigate the effects of recharge duration and frequency on the efficacy oftion re-release. The rechargeable cement consisted of pyromellitic glycerol dimethacrylate (PMGDM) and ethoxylated bisphenol A dimethacrylate (EBPADMA). NACP was mixed into the resin at 40% by mass. Specimens were tested for orthodontic bracket shear bond strength (SBS) to enamel, Ca and P ion initial release, recharge and re-release. The new orthodontic cement exhibited an SBS similar to commercial orthodontic cement without CaP release (P>0.1). Specimens after one recharge treatment (e.g., 1 min immersion in recharge solution repeating three times in one day, referred to as"1 min 3 times") exhibited a substantial and continuous re-release of Ca and P ions for 14 days without further recharge. The ion re-release did not decrease with increasing the number of recharge/re-release cycles (P>0.1). The ion re-release concentrations at 14 days versus various recharge treatments were as follows:1 min 3 times>3 min 2 times>1 min 2 times>6 min 1 time>3 min 1 time>1 min 1 time. In conclusion, although previous studies have shown that NACP nanocomposite remineralized tooth lesions and inhibited caries, the present study developed the first orthodontic cement with Ca and P ion recharge and long-term release capability. This NACP-rechargeable orthodontic cement is a promising therapy to inhibit enamel demineralization and WSLs around orthodontic brackets.

Objective To evaluate the use of gated SPECT in patients with hypertrophic obstructive cardiomyopathy (HOCM) and the effects of percutaneous transluminal septal myocardial ablation (PTSMA) on myocardial perfusion.Methods 99 Tcm-methoxyisobutylisonitrile (MIBI) and 18F-fluorodeoxyglucose (FDG) images were performed in 31 HOCM patients before PFSMA and in 15 patients 3-7 d after PTSMA.The images in different left ventricular segments were analysed by using scores.Results In 99Tcm-MIBI images, uptake decreased at the septal regions in 12 HOCM patients (80.0%, 12/15) after PTSMA, 18F-FDG images also showed decreased uptake at the septal regions in 5 HOCM patients (33.3%, 5/15) after PTSMA.Conclusion 99Tcm-MIBI images might be an important method to evaluate PTSMA results, and 18 F-FDG images showed important value as reference.

Objective: To investigate the value of thoracoscopy in diagnosis and treatment of pleural diseases in children. Method: Clinical manifestations and treatment outcomes of 19 patients who had refractory pleural diseases treated with thoracosocy during May 2011 to August 2016 in Hunan Provincial People′s Hospital were retrospectively analyzed. In 19 cases, 15 were male and 4 were female, with an average age of (4.8±2.0) years. Thirteen patients had left pleural lesion, while 5 patients had right lesion, and 1 had bilateral lesions. Result: All cases were successfully treated with thoracoscopy without emergent thoracotomy. Pre- and post operative diagnosis was compatible in 10 cases, including 8 cases of empyema (Streptococcus pneumoniae infection in 6 cases, and Staphylococcus Aureus infection in 2 cases), and 2 cases of tuberculous pleuritis. Nine patients who had not been clearly diagnosed before surgery were diagnosed to be empyema (4 case), tuberculous pleuritic (3 cases), mycoplasma infection (1 case), and foreign body with infection (1 case) by thoracoscopy. The average duration of post-op closed thoracic drainage was (4.7±2.3) days. The average time to get normal temperature was (2.4±2.6) days. And the average length of hospital stay was (6.7±1.8) days. No hemothorax, chylothorax, or need for analgesic occurred. Conclusion Thoracoscopy can be recommended for diagnosis and treatment of refractory pleural lesions diseases in children, with minimal trauma and complications.

Objective To study the workplace violence situation of hospital setting and explore its influence on the psychological health status of nurses.Methods A descriptive and correlative design was used.By cluster sampling,932 nurses from three hospitals in Shenzhen were recruited.The Workplace Violence in Hospital Setting Questionnaire and the Symptom Checklist 90 were used to measure the status of workplace violence in hospital setting and the level of psychological health status of nurses.The data were analysed with software SPSS version 12.0.Results The overall incidence rate of workplace violence was 64.3％ with psychological violence 86.0％,physical violence 20.9％,sexual violence 11.5％.The scores of psychological health and 9 dimensions score of nurses suffering from workplace violence were significantly higher than that of nurses without suffering from workplace violence ( Z =- 9.734,P ＜ 0.01 ).The more frequence of working violence they suffered,the higher the score of psychological health of nurses they have( P ＜0.01 ),and there was significantly difference in the frequence of psychological violence,the score of psychological health and its dimension(P ＜0.01 ).The frequence of physical violence and sexual violence was no correlation with the score of psychological health ( P ＞ 0.05 ).The more frequence of working violence is,the higher scores on psychological health status of nursing staff were.( P ＜ 0.05 ).Conclusions The overall incidence rate of workplace violence was high.The psychological health status of nurses suffering from workplace violence was lower than that of nurses without suffering from workplace violence.The more frequence of working violence,the poorer the psychological health status of nurses.

To further explore the mechanism of congenital pyrimidine 5'-nuleotidase I (P5'N-I) deficiency, on the basis of purification of the protein, the molecular weight and amino acid composition were analysed by mass-spectrograph and amino-acid analyzer, microsequencing and bioinformation analysis of P5'N-I were performed after it was hydrolysed by trypsin. The results showed that three fractions were found in the purified P5'N-I and their molecular weights were 26,952.9, 55,476 and 110,938, respectively. The sequence from one of the peptide fragments was I-E-G-P-T-I-R-Q-I-E. The homologous sequence was not found after comparision with the ten-amino-acid sequence in GenBank by blast procedure. Amino acid analysis indicated that P5'N-I was composed of 18 amino acids at least, and 243 amino acid residues. In conclusion, the enzyme might be an allosteric enzyme, there might be homologous dimer or tetramer in physiological status of normal human erythrocyte, the microsequence could be designed as the probe for fishing the genes of interest. The composition of amino acid might be an important information in determination of its protein primary structure.
