ABSTRACT
Objective@#To study the correlation between low back pain (LBP) and occupational stress in coal miners.@*Methods@#From January 2015 to December 2016, a total of 472 front-line workers in a mining area of a large-scale coal mining enterprise in Shanxi, China were enrolled in the study. The general information, condition of LBP, and occupational stress level of the subjects were obtained by questionnaire survey. Dichotomous logistic regression (DLR) was used to analyze the correlation between LBP and occupational stress.@*Results@#Of the 472 subjects, 186 subjects experienced LBP in the past year; the prevalence rate of LBP was 39.41%. The scores of the Occupational Role Questionnaire were significantly higher for workers in the LBP group than in the non-LBP group (P<0.01) . As revealed by the DLR analysis, age, marital status, length of service, occupational stress role, labor intensity, keeping single posture during work, and working in shifts were risk factors of LBP (P<0.01) , while smoking may be a protective factor against LBP (P<0.01) .@*Conclusion@#Occupational stress role is a potential risk factor for LBP in coal miners (P<0.01) . Reasonable work assignment and timely alleviation of occupational stress may be one of the effective approaches to prevent LBP.

ABSTRACT
Objective To evaluate the diagnostic value of gastrin?17( G?17) and pepsinogen( PG) for gastric cancer. Methods A multicenter cross?sectional study of patients with continuous stomach discomfort from four centers including Changhai Hospital Affiliated to Second Military Medical University, the First Hospital Affiliated to Anhui Medical University, Qinghai Provincial People′s Hospital and the First Hospital Affiliated to Zhejiang University of Chinese Medicine from May 2014 to September 2015 was conducted. Before gastroscopy, fasting serum gatrin?17 and pepsinogen were analyzed by enzyme?linked immunosorbent assay(ELISA). The efficacy of G?17 and PG were evaluated according to endoscopic and pathological results. Results Based on the results of the pathological diagnosis, 1 122 cases were enrolled and divided into chronic atrophic gastritis group ( 548 cases ) , chronic non?atrophic gastritis group ( 370 cases), and gastric cancer group(204 cases). Serum G?17 and PGⅡ levels significantly increased(P7 pmol/L and PGR7 pmol/L and PGⅡ>10μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 48?04%, 79?74%, 73?98%, 34?51% and 87?35% respectively. If PGR10 μg/L was regarded as the cut?off value, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value were 33?82%, 84?86%, 75?58%, 33?17% and 85?23% respectively. Based on logistic regression analysis of the independent variables of high serum G?17 value(>7 pmol/L), low serum PGR value(10 μg/L), their OR value were 2?592, 2?237 and 1?864 respectively, and high serum G?17 value showed the highest risk of gastric cancer. Conclusion High serum G?17 and PGⅡ, low PGR are indicators of gastric cancer. Combination of G?17 and PGR has the best diagnostic value for gastric cacer. Gastric cancer can be screened in large scale by combining G?17 and PGR in order to improve the early diagnostic rate of gastric cancer and reduce the mortality of gastric cancer in our country.
ABSTRACT
This study was aimed to investigate the effect ofDanlou pills on prevent atherosclerosis from hypercholesterolemia rabbit and its relationship with inflammatory factors as well as PI3K/AKT signal pathways. A total of 24 Japanese male white rabbits were randomly divided into the control group (CL), model group (M) and Danlou group (DL), with 8 in each group. Normal diet was given to CL rabbits. High-fat diet was given to rabbits in other groups to establish the atherosclerosis model. Danlou pills (0.5 g·kg-1·d-1) were also given to DL rabbits. Rabbits were sacrificed after 9-week medication. The contents of blood lipid, TNF-α and IL-6 were detected. HE staining was used in the observation of histological changes in the aorta. Western blot was used to observe PI3K and p-AKT expression in the aorta. The results showed that compared with CL, the contents of TG, TC, LDL, IL-6 and TNF-α were significantly increased in M (P < 0.01); PI3K and p-AKT expression in the aorta were significantly decreased (P < 0.01). Compared with M, blood lipid, IL-6 and TNF-α were significantly reduced in DL (P < 0.05, orP < 0.01); PI3K and p-AKT expression were significantly increased (P < 0.01). It was concluded thatDanlou pills had prevention effects on atherosclerosis through reducing blood lipid and inflammatory factors. The action mechanism maybe related to the activation of PI3K/AKT signal pathways.
ABSTRACT
This study was aimed to observe the safety and effectiveness ofShugan Jieyu Capsules in the treatment of vasovagal syncope (VVS) with mild-to-moderate depression and anxiety, and to compare the effect with Flupentixol and Melitracen Tablets. A total of 89 VVS cases with mild-to-moderate depression and anxiety were randomly divided into 3 groups, which were group A (Shugan Jieyu Capsules group), group B (Flupentixol and Melitracen Tablets) and group C (control group). Based on the conventional therapy of VVS treatment, treatments were given to all three groups for 8 weeks. And the negative conversion ratio of VVS in each group was observed. Hamilton Depression Scale (HAMD 24 items) and Hamilton Anxiety Scale (HAMA) were evaluated for the calculation of reductive rate. Treatment emergent symptoms scale (TESS) was used in the evaluation of adverse reactions of both medications during the treatment. In the 12-month follow-up after treatment, the recurrence rate of syncope was observed in each group. The results showed that compared with pretreatment, HAMD-24 and HAMA scores of group A and group B after treatment were significantly reduced (P < 0.05). Compared with group C, the heat-up tilt testing-negative rate, HAMD-24 and HAMA reductive rate of group A and group B after treatment were significantly increased (P < 0.05). Compared with group B, the negative rate, HAMD-24 and HAMA reductive rate of group A were more significant (P < 0.05). After treatment, scores for TESS of group A was significantly lower than group B (P< 0.05). In the 24-month follow-up, the recurrence rate of syncope of group A and group B was significantly lower than group C (P < 0.05); and group A was obviously better than group B (P < 0.05). It was concluded thatShugan Jieyu Capsules can be used in the treatment of VVS with mild-to-moderate depression and anxiety. Its effectiveness and safety may be better than Flupentixol and Melitracen Tablets.
ABSTRACT
With the increasing incidence and mortality of coronary heart disease (CHD) in China, the prevention and treatment of CHD is no time to delay. Since Professor Gruentzig completed the first human case of percutaneous transluminal coronary angioplasty (PTCA) in 1977, percutaneous coronary intervention (PCI) had reached to a new page. After three decades of development and change, PCI has been improved and matured gradually from the early PTCA to the current stent era. With the advent of stents, the rate of restenosis after PCI was significantly reduced from 30%-50% to 10%-20%. But stent restenosis was still with no total cure. The issue of how to prevent the stent restenosis has become a long-term major issue for the exploration in both clinical and preclinical medicine. Therefore, this paper reviewed the etiology, pathology, related risk factors, latest diagnosis methods, prevention and treatment of stent restenosis by integrative medicine.
