ABSTRACT
Objective@#To explore the prevalence of occupational musculoskeletal disorders (OMD) and its influencing factors among rural migrant workers in Tianjin, with the aim of developing strategies to improve the health condition of this specific population.@*Methods@#Questionnaire survey was conducted among 415 rural migrant workers working in Tianjin about their fundamental state and occupational musculoskeletal disorders (OMD) during January 2015 to January 2016. Statistical methods were utilized to analyze the influencing factor.@*Results@#A total of 415 rural migrant workers were investigated, in which young Young adults and low education level were in the majority of rural migrant workers. The prevalence of OMD for whole population, male and female were 28.92% (120/415), 33.06% (81/245) and 22.94% (39/170), respectively. Prevalence showed significant differences njin and workplace hygiene. Multivariate logistic regression analysis showed that the risks of OMD increased with age group, and decreased with higher education level. The risk of OMD among rural migrant workers with monthly income between 3000 to 5000 yuan was 2.26 times (95%CI: 1.37-3.75) higher than that of low-income workers (<3000 yuan per month). Workers engaged in housekeeping service had 2.28 times higher risk of OMD than those in manufacturing industry (95%CI: 1.06-4.89) .@*Conclusion@#Prevalence of OMD among rural migrant workers is higher than that of general people. Age, education, monthly income, occupation are the independent influencing factors for OMD among rural migrant workers.
ABSTRACT
Objective To explore the effect of combined prescription medication on non-dipper hyperten sive patients.Methods 76 patients with non-dipper hypertensive patients were randomly divided into group A (n =38) and group B (n =38).Telmisartan tablets,hydrochlorothiazide tablets and levamlodipine tablets were given in two groups.Patients in group A take oral medicine at 8 pm,and patients in group B take oral medicine at 8 pm.The levels of plasma angiotensin Ⅱ,plasma endothelin-1 (ET-1),plasma renin,matrix metalloproteinase9 (MMP-9) and Chemerin protein were observed in both groups.Results After treatment,24 h SBP,dSBP and nSBP in group B were significantly lower than those in group A (P ＜ 0.05).The dipper value of group B was significantly higher than that of group A (P ＜ 0.05).The diversion rate of group B was significantly higher than that of group A (P ＜ 0.01).The levels of renin,angiotensin Ⅱ,ET-1,MMP-9 and Chemerin in group B were significantly lower than those in group A at 6 AM and 0:00 (P ＜ 0.05).The degree of change in group B at 0:00 was more significant than that in 6:00 AM (P ＜ 0.05).There was no significant difference in the incidence of adverse reactions between the two groups (P ＞ 0.05).Conclusion The efficacy of telmisartan,hydrochlorothiazide combined with levamlodipine in patients with non-dipper hypertensive patients performs better if patients take medicine at 8 pm other than at 8 pm.
ABSTRACT
Objective: To investigate the efficacy and safety of oxycodone hydrochloride prolonged-release tablets and tramadol hydrochloride sustained-release tablets in the treatment of moderate cancer pain. Methods:Totally 290 cases of the patients with mod-erate pain were divided into the observation group with 148 cases and the control group with 142 cases. The observation group received oxycodone hydrochloride prolonged-release tablets, while the control group was given tramadol hydrochloride sustained-release tablets. The treatment course was 2 weeks, and the total efficiency and the incidence of adverse drug reactions( ADR) in the two groups were calculated and compared. Results:The total efficiency in the observation group and the control group was 92. 6% and 81. 7%, respec-tively, and the difference was statistically significant (P0.05). Conclusion: The effect of oxycodone hydrochloride prolonged-release tablets in the treatment of moderate cancer pain is better than that of tramadol hydrochloride sustained-release tablets.
ABSTRACT
Objective To compare the potential cytotoxicity induced by Veratrum nigrum coadministered with Panax ginseng, and to provide experimental evidence on the mode of herb-herb interaction based on human liver drug metabolizing enzymes.Methods The effect of V.nigrum and coadministration on cultured human hepatoma (HepG2) cells was investi-gated by detecting morphological changes , cell viability , cytomembrane integrity and apoptosis after the cells were treated for 24 h.The mRNA expression levels of drug metabolizing enzymes influenced by P.ginseng were determined by real-time quantitative reverse-transcriptase polymerase chain reaction .Results V.nigrum coadministered with P.ginseng had a better inhibitive effect on the growth of HepG2 cells at the IC50value of (15.18 ±1.03) mg/ml than at the value of IC50 (21.46 ±1.10) mg/ml of V.nigrum.Coadministration more significantly raised the LDH level in cell culture medium than at the same dose of V.nigrum.Moreover, in coadministration group, compared with the same dose of V.nigrum,the total apoptosis and necrosis of HepG2 cells were significantly increased .P.ginseng had effect on the expression of CYP3A4, CYP1A1, CYP1A2, CYP2B6 and CYP2E1 mRNA.Conclution Compatibility of medicines in a prescription also has herb-herb interactions based on drug metabolizing enzymes .The interaction mode is that the P.ginseng inhibits and induces CYPs and the modulated CYP isozymes ,inturn,have an impact on the metabolism of constituens in coadministered herbs causing herb-herb interaction .
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expression of fragile histidine triad (FHIT) gene protein, FHIT and the possible relationship between FHIT expression and clinicopathological indices in colorectal carcinoma.</p><p><b>METHODS</b>Detecting FHIT protein expression in 60 cases of formalin-fixed, paraffin-embedded colorectal carcinoma by citrate-microwave-SP immunohistochemical method, and analyzing its relationship to histological grade, Dukes' stage and 5-year survival rate.</p><p><b>RESULTS</b>55% of the carcinomas showed a marked loss or absence of FHIT expression compared with their matched normal mucosa. Carcinomas with reduced expression of FHIT correlated with their histological grade, Dukes' stage (P < 0.05) and 5-year survival rate. The distribution of decreased expression of FHIT was 7/16 in grade I carcinoma, 14/30 in grade II, 12/14 in grade III, respectively. The correlation between decreased expression of FHIT and Dukes' staging was 5/11 in stage A, 12/28 in stage B, and 16/21 in stage C. The difference between stage A, B with no lymph nodes metastases and the stage C with lymph nodes metastases was of significance (P < 0.05). The follow-up data of 39 cases showed that in the 5-year survival group, 13/25 were of the low FHIT expression carcinomas, while in 5-year deceased group 12/14 were of the low FHIT expression carcinomas (P < 0.05).</p><p><b>CONCLUSIONS</b>The reduced expression of FHIT may be associated with decreasing differentiation, metastasis and 5-year survival rate in colorectal carcinoma. It is suggested that decreased FHIT expression plays an important role in the development and progression of the tumor, and thus may become a new prognostic marker in colorectal carcinoma.</p>

By using digoxin labelled human papillomavirus(HPV) 6/11 and HPV16/18 probes,and hybridization in situ technique, the HPV DNA sequence in 50 cases of oral SCC was detected. The results showed that among them ,16 cases(32%) were positive for HPV16/18 DNA, none of the cases of OSCC was positive for HPV6/11 DNA. It was suggested that HPV16/18 in oral SCC was confirmed to be closely related with the cause of OSCC.
