BACKGROUND:Whether a long-term use of acid-suppressive medication for over 3 years can increase the risk of fractures, remains controversial.
OBJECTIVE:To systematical y review the effect of acid-suppressive medication on fracture risk.
METHODS:Clinical trials about the relationship of acid-suppressive medication use and risk of osteoporosis-related fractures were searched in MEDLINE, Cochrane Library, EMbase, and CNKI database. We also manual y searched some published and unpublished references. Study selection and assessment, data col ection and analyses were undertaken by two reviewers independently. The Cochrane Col aboration’s RevMan 5.0 software was used for data analyses.
RESULTS AND CONCLUSION:After a comprehensive search, 11 original clinical trials were included in this meta-analysis, including 3 nested case-control studies, 5 case-control studies, and 3 cohort studies. Patients with fractures were more likely than controls to have previously received supply of proton pump inhibitors [odds ratio (OR)=1.29, 95%confidence interval (CI) (1.18-1.41), P<0.001]. The meta-analysis did not find a significant difference in the patients who received H2 receptor antagonists [OR=1.10, 95%CI (0.99-1.23), P=0.34]. A long-term use of proton pump inhibitors is associated with an increased risk of fracture in elderly persons already at a risk for osteoporosis.

ObjectiveTo investigate the relationship between intervertebral disc pressure and clinical efficacy after the minimally invasive treatment of cervical disc herniation. MethodsForty-seven patients with cervical disc herniation treated by disc radiofrequency ablation, and monitored the intervertebral disc pressure after that. Moreover, the correlation between the pressure and the clinical efficacy was observed. ResultsAll cases were successfully completed under pressure monitoring. Forty-seven cases underwent a follow-up of 1-25 months,according to JOA score,using postoperative improvement rate (Hirabashi formula) to assess the clinical efficacy. High efficacy in 25 cases,fine efficacy in 19 cases,good efficacy in 3 cases,high and fine efficacy rate was 93.6％ (44/47). The postoperative intervertebral discpressure was significantly correlated with improvement rate after cervical minimally invasive surgery (P ＜0.05). ConclusionsRadiofrequency ablation treatment of cervical disc herniation is safe and effective minimally invasive technique. If the pressure in the postoperative intervertebral disc is 3 kPa,it will get better prognosis.

Objective To observe the changes of plasma IL-8 levels and their association with the severity of and the passage of time after inhalation injury. Methods The plasma was separated from blood samples of 27 patients 12 h, 1, 2, 4 and7 d after inhalation injury. The IL-8 level in the plasma was determined by ELISA. Result IL-8 levels were significantly increased on day 1 and kept a high level for a period over 7 d. Conclusion Inhalation injury can induce the production of IL-8, and IL-8 level is positively correlated with the by severity of inhalation injury.

Objective To investigate the relationship between arsenic in drinking water and skin lesions in endemic arsenism area in Shanyin County of Shanxi Province,in order to provide epidemiologic data for further arsenism research.Methods One hundred and eighty-nine endemic arsenism patients and 59 controls were randomly selected in 17 endemic amenism countries in Shanyin County of Shanxi Province.The content of arsenic in drinking water which wa8 collected indoom was half-quantitatively screened by a kit made by Chinese Center for Disease Control and Prevention,then quantitatively determined by HPLC-ICP-MS.Patients of endemic arsenism were diagnosed by "The Standard of Diagnosis for Endemic Amenism"(WS/T 211-2001).Results There were 64.9% (87/134)samples above the arsenic level(50μg/L)of drinking water and the median value of arsenic in drinking water was 91.43 μg/L in 134 water samples.The OR(95%CI)value between arsenic in drinking water and hyperkeratosis,hyperpigmentation,depigmentation was 2.46(1.22-4.94),3.34(1.50～7.44)and 2.86(1.50-5.46),respectively.The prevalence of hyperkeratosis,hyperpigmentation and depigmentation increased,as the arsenic in drinking water increased(≤10,≤50,≤200,＞200μg/L),especially in＞200μg/L group(OR=6.15,13.96,11.41,P＜0.05).The arsenic level in drinking water of Ⅲ degree of depigmentation patients(318.300μg/L)was higher(P＜0.05)than that of 0,Ⅰ and Ⅱ degree groups(86.670,131.800,1 10.590μg/L,P＜0.05).Conclusions Shanyin County is a medial arsenic pollution area. Arsenic in drinking water is considered as a risk factor of skin lesion. The degree of skin lesions increased,as the arsenic in drinking water increased.

Objective To learn the present status of defluoridation water improvement project in Shanxi province in order to provide scientific basis for speeding up the prevention and control of endemic fluorosis.Methods According to "The National Technical Scheme for Endemic Disease Control" from 2005 to 2009, the investigation points were selected in the counties that implemented the measures of water improvement and defluoridation,the status of drinking water defluoridation Project was investigated, and the water fluoride levels were determined by fluoride selective ion electrode. Results The primary status was surveyed in 1658 water improvement and defluoridation projects in 51 counties. The resource of drinking water for water improvement and defluoridation projects was mostly ground water[accounting for 93.12% (1544/1658)]. Among 1658 water improvement and defluoridation projects 1405 projects worked well(accounting for 84.74%) and 190 projects intermittently worked (accounting for 11.46%). Sixty three projects abandoned (accounting for 3.80%), in Datong basin the abandoned projects accounted for 36.36% (12/33). Water fluoride content of 1595 water improvement and defluoridation projects had been determined, among them water fluoride content of 874 projects were above 1.0 mg/L (accounting for 54.80%). The situations of exceeded national standard in the five basins was different(H = 33.22,P ＜ 0.01). The rate of over national standard of fluoride levels in drinking water was 88.37%(38/43) in Datong basin. Therefore, in Datong basin water improvement should be strengthened. Conclusions In Shanxi province the water improvement and defluoridation projects are basically running normally. However, the qualified rate is lower for the water improvement and defluoridation projects. The water improvement status varies dramatically among areas.The situation is still grim in Shanxi province. Water improvement and defluoridation needs to be strengthened to improve the effect of prevention and control of the disease.

Objective To analyze the relationships between the drinking water fluoride and bone mineral density (BMD), and serum osteocalcin (BGP) and to explore the BMD and serum BGP as significant early screening biomarkers for fluorosis especially for early bone damage in endemic fluorosis areas. Methods Wamiao (severe endemic fluorosis area, as fluoride exposed group) and Xinhuai (non endemic fluorosis area, as control group) Village were selected in 2006. One hundred and fouty-six objects were chosen from 2 villages (103 in Wamiao, 43 in Xinhuai). The sex, age, body height, body weight, drinking water fluoride in each object's household well, BMD, and serum BGP were investigated, and the dose-response relationships were analyzed between the drinking water fluoride and BMD, and serum BGP. CurveExpert 1.3 Software was used to fit the dose-response relationships between the rate of abnormal BMD, the rate of abnormal serum BGP, and the drinking water fluoride. Results The levels of drinking water fluoride in males' and females' families in fluoride exposed group were [(2.38±0.68), (2.62±0.91 )mg/L] significant higher than that in control group [(0.35±0.08), (0.36±0.07)mg/L], the difference being statistically significant(t values were 14.27 and 11.08,and P<0.01, respectively). BMD in males in fluoride exposed group [(0.78±0.07)g/cm2] was significant lower than that in control group[(0.83±0.08)g/cm2], the difference being statistically significant (t=2.37,P<0.05). Serum BGP in males and females in fluoride exposed group [(4.17±0.67), (4.11±0.57) μg/L] were significant higher than that in control group [(1.48±0.40), (1.44±0.39)μg/L], the difference being statistically significant (t values were 17.64 and 19.40, and P<0.01, respectively]. BMD in the group with drinking water fluoride≥2.92 mg/L[(0.66±0.15 )g/cm2] was significant lower than that in the group with drinking water fluoride<0.42 mg/L [(0.76±0.12)g/cm2], the difference being statistically significant (P<0.01). The levels of serum BGP in the groups with the drinking water 0.42-,2.05-, ≥.92 mg/L[(3.83±1.07), (4.22±0.72), (3.99±0.63) μg/L] were significant higher than that in the group with the drinking water<0.42 mg/L [(1.44±0.37) μg/L], the difference being statistically significant (P<0.01). The equation for the dose-response relationship between the drinking water fluoride and the rate of abnormal BMD was y=(0.284-0.058x)-1.260, r=0.999 94; and y=100.05/(1+78.62e-4.5x), r=0.999 99 for the drinking water fluoride and the rate of abnormal serum BGP. Conclusions There were significant dose-response relationships between drinking water fluoride and BMD and serum BGP. It indicated that BMD and BGP might be considered as early screening biomarkers for endemic fluorosis, especially for the bone damage.
