OBJECTIVETo investigate the effects of recombinant human growth hormone on serum lipid in aged male patients with chronic heart failure (CHF).

METHODSEighty seven patients with chronic heart failure(> or = 60 years old) were randomly divided into 2 groups: the CHF control group (n = 46) who received regular therapy and the CHF experimental group (n = 41) who received regular therapy and recombinant human growth hormone. The treatment would be continued for 3 months. Another group was normal control group (n = 10). The detection of serum growth hormone (GH), insulin-like growth factor (IGF-1), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) was carried out before and after treatment in the participants.

RESULTSBefore treatment, the levels of GH and IGF-1 were not significantly different among groups. After treatment, the levels of GH (0.71 +/- 0.34 vs 0.96 +/- 0.48) and IGF-1 (95.64 +/- 21.11 vs 111.64 +/- 23.14)in CHF experimental group were higher than those before the treatment. In CHF control group, the levels of GH(0.81 +/- 0.32 vs 0.79 +/- 0.29) and IGF-1 (97.82 +/- 19.74 vs 99.65 +/- 20.11) had no significant change after the treatment. After treatment, the levels of GH (0.96 +/- 0.48 vs 0.79 +/- 0.29) and IGF-1 (111.64 +/- 23.14 vs 99.65 +/- 20.11) in CHF experimental group were higher compared with that of CHF control group. Before treatment, the serum levels of LDL-C, HDL-C, TC and TG had no significant difference among groups. After treatment,the levels of LDL-C (2.11 +/- 0.82 vs 1.76 +/- 0.51) and TC (3.78 +/- 1.34 vs 3.21 +/- 1.17) in CHF experimental group were lower than those before the treatment. However, the levels of HDL-C (1.10 +/- 0.31 vs 0.99 +/- 0.28)and TG (1. 89 +/- 1.07 vs 1.66 +/- 0.95) had no significant change after the treatment compared with before treatment. In CHF control group, the serum lipid levels had no significant change after the treatment.

CONCLUSIONAs the treatment of rhGH for aged male patients with chronic heart failure, GH influences lipid metabolism, which reduces the level of LDL-C, TC. However GH has no effects on the serum HDL-C and TG level. With the treatment of rhGH for long-term, lipid metabolism should be paid attention,and the treatment for blood lipid reduction should be adjusted in time.

BACKGROUND:Panax notoginseng saponins promotes bone repair by improving vascular proliferation. Therefore, the scaffolds carrying panax notoginseng saponins were supposed to be used to improve bone repair at the bone defect region. However, the biocompatibility of scaffolds remains unclear.
OBJECTIVE:To evaluate the biocompatibility of panax notoginseng saponins-hydroxyapatite/chitosan scaffolds.
METHODS:A new bone repair scaffold has been generated by thoroughly mixtures of 0, 0.1, 1, 10 mg panax notoginseng saponins and chitosan/hydroxyapatite using in-situ composite technique and freeze-drying technique. Morphology and mechanical property of the scaffold were observed under a scanning electron microscope. (1) Cel proliferation test:rabbit bone marrow mesenchymal stem cel s of passage 3 were cultured in four kinds of drug loaded hydroxyapatite/chitosan composite material leaching liquor. Cel s normal y cultured were considered as controls. 3-(4, 5-Dimethylthiazol-2-yl) 2, 5-diphenyl tetrazolium bromide was used to measure absorbance value of cel s in each group. (2) Hemolysis test:Rabbit anticoagulated blood was added with four kinds of drug loaded hydroxyapatite/chitosan composite material leaching liquor. Absorbance values were measured using a microplate reader in each group. (3) Pyrogen test:The four kinds of drug loaded hydroxyapatite/chitosan composite material leaching liquor and saline were respectively injected into ear vein of rabbits, and the increase of rabbit body temperature was detected.
RESULTS AND CONCLUSION:Drug loaded hydroxyapatite/chitosan composite material contained three dimensional porous structure of 110μm in diameter. Drug loading process of panax notoginseng saponins did not significantly affect the porosity, pore size and density of the composite material, but decreased its breaking strength and elastic modulus. The larger amount of drug loading showed a more obvious effect. Simple hydroxyapatite/chitosan composite material had good cel ular compatibility. The composite material after drug loading obviously suppressed cel proliferation, and the larger amount of drug loading showed a more obvious effect. The composite material had good blood compatibility before and after drug loading. The composite material had good pyrogen effects before and after drug loading, but accorded with acceptable quality level of pyrogen test.

Objective: To compare the efifcacy and safety of rivaroxaban and warfarin on thrombolytic disease prevention in very elderly patients. Methods: A total of 90 patients with high risk of venous thrombosis treated in our hospital from 2012-03 to 2014-03 were enrolled. The patients' mean age was (82.4±5.5) years and randomized into 2 groups: Rivaroxaban group, patients received oral rivaroxaban 10 mg/day,n=44 including 34 male and 10 female; Warfarin group, patients received oral warfarin, INR was monitored and kept at stable level of 1.6-2.5,n=46 including 38 male and 8 female. All patients were followed-up for 12 months. Hemoglobin and platelet levels, coagulation, liver and kidney functions, end point events were monitored before and 1, 3, 6, 12 months after treatment. Major efficacy endpoints included all-cause death, recurrent or new onset of venous thrombosis, pulmonary embolism, cerebral and cardiovascular events; major safety endpoints included massive hemorrhages, clinically relevant bleeding and worsening of liver, kidney functions. Results: No patient died during follow-up period. The average INRs in Warfarin group were (2.02±0.46), (1.98±0.54), (2.03±0.56) and (2.04±0.46) at 1, 3, 6 and 12 months of treatment. Efficacy and safety were similar between 2 groups, Warfarin group had 7 patients with massive hemorrhages at 12 months of treatment and it was 2 patients more than that in Rivaroxaban group which had no statistic meaning. Hemoglobin and platelet levels, coagulation, liver and kidney functions were similar between 2 groups.Conclusion: Oral rivaroxaban was effective for preventing thromboembolic disease in very elderly patients, 10 mg/day was a safe dose; efifcacy of rivaroxaban was similar to warfarin while it was easier to use and with better compliance.

Objective To investigate the clinical value of the combined detection of Golgi protein 73 (GP73),alpha-fetoprotein variant-L3 (AFP-L3)and transforming growth factorβ1(TGFβ1)in the early diagnosis of hepatocellular carcinoma (HCC).Meth-ods 48 cases of healthy control,42 cases of hepatitis B,50 cases of posthepatitic cirrhosis and 58 cases of HCC were selected and detected GP73,AFP-L3 and TGFβ1.The detection results were compared among 4 groups.Results (1)The levels of GP73,AFP-L3 and TGFβ1 had statistical differences among 4 groups(P <0.05 );(2 )The positive rate of the 3-marker combined detection reached 96.55%,which was higher than that of the 2-marker combined detection and the single marker detection.Conclusion (1) GP73,AFP-L3 and TGFβ1 may be used as the serum indicators for the early diagnosis of HCC;(2)Compared with the traditional HCC marker AFP,AFP-L3 has relatively high sensitivity and specificity and has the important role in the differential diagnosis of benign and malignant diseases of the liver,which is considered as a better serum marker in the HCC diagnosis;(3)The 3-indicator combined detection can significantly improve the positive detection rate of HCC and has better application value.

Objective To investigate the prevalence of endemic fluorosis in Guide county of Qinghai province, in order to provide appropriate measures to monitor and control the disease. Methods Damo, Wenquan, Baoning villages(water source has been changed) and Taiping village(water source has not been changed) in Guide county were involved in the study in 2008. One tap water sample was collected in dry and rainy seasons, respectively. Water fluoride was tested in accordance with the "Standard Test Methods for Drinking Water" (GB/T 5750.5-2006); of all the children aged 8 to 12, dental fluorosis was diagnosed using Dean criteria; 6 copies of urine samples were collected in each age group, urinary fluoride was measured using fluoride ion-selective electrode (WS/T 89-1996). According to the "Clinical Diagnostic Criteria of Endemic Skeletal Fluorosis "(WS 192-2008), clinical skeletal fluorosis was determined in adults over the age of 16 by X-ray examination for 10 people in each selected village. Results The mean water fluoride was 0.58,0.38,2.28,0.37 mg/L in Damo, Wenquan, Taiping, and Baoning villages, respectively, and that of Taiping village exceeded the national standard(1.0 mg/L). One hundred and ninety-three children aged 8-12 were checked, the detection rate of dental fluorosis was 49.74% (96/193); urine samples of 116 children were tested, median urinary fluoride was 1.49 mg/L A total of 1503 adults over the age of 16 were examined, the clinical detection of skeletal fluorosis was 51.63%(776/1503); a total of 82 people were X-rayed, X-ray detection of skeletal fluorosis was 20.73%(17/82). The characteristic of X-rays were degeneration and ossification of interosseous membrane. Conclusions Prevalence of dental fluorosis of children and adult clinical skeletal fluorosis are higher. The endemic fluorosis is still comparatively serious. Prevention efforts need to be further strengthened.
