OBJECTIVE: To analyze the reproductive health status of female employees in an automobile manufacturing industry and its influencing factors. METHODS: By a method of convenient sampling, 989 female employees of an automobile manufacturer were selected as the study subjects. The Female Employees′ Reproductive Health Status Questionnaire was used to investigate and analyze the influencing factors. RESULTS: The prevalence of abnormal menstruation was 23.7%(234/989). The abnormal menstruation was mainly the menstrual cycle disorder, with the prevalence of 15.4%(152/989). The prevalence of reproductive tract infection was 39.1%(387/989), and the top 2 types of infection were cervicitis(12.7%) and vaginitis(12.1%). The results of multivariate logistic regression analysis showed that the risk of abnormal menstruation in night shift workers was higher than that in day shift workers(P<0.05). The risk of abnormal menstruation increased in female workers with the increase of work intensity(P<0.05). Female workers with a history of abortion had higher risk of abnormal menstruation and reproductive tract infection than those without a history of abortion(all P<0.05). Female workers with abnormal menstruation had a higher risk of reproductive tract infection than those with normal menstruation(P<0.01). Married employees had a higher risk of reproductive tract infection than unmarried ones(P<0.01). CONCLUSION: The reproductive health of female workers in the automobile manufacturing industry is related to their marital status, work shift, work intensity and history of abortion.

Purpose To explore the effects of estrogen receptor antagonist on the expression of estrogen receptor subtype (ERα, ERβ), and p57kip2 protein in human endometrioid carcinoma cells named JEC. Methods The JEC cells (moderately differentiated EC cells) cultured in vitro were treated with β-Estradiol (E2) (10~6 mol/L) and two types of estrogen receptor antagonists, tamoxifen (TAM) and fulvestrant (ICI182780) (10-6 mol/L). After 24, 48, 72 h, MTT was used to detect the growth condition of JEC cells, and the light microscopy and electron microscopy were used to observe the growth condition and morphological changes of cells, Western blot was used to detect the expression of ERα, ERβ, PR-A, PR-B and P57kip2 protein in JEC cells. Results MTT results: Compared with the control group, E2 could promote the proliferation of JEC cells significantly (P<0.05), and ICI182780 could inhibit the proliferation of JEC cells obviously (P<0.05). Compared with the E2 group, the proliferation ability of JEC cells in E2 + ICI182780 group were lower(P<0.05). Morphological change: Compared with the control group, the cells density of E2 group increased obviously, and the pathologic mitosis was easy to seen in some cells. The cells density decreased obviously in ICI182780 group. Compared with E2 group, the cells density of E2 + TAM group and E2 + ICI182780 group were decreased, and pathological mitotic figures were difficult to seen. Western blot results: Compared with the control group, the expression of ERβ protein increased, and the expression of p57kip2 protein decreased in E2 group (P<0.05). The expression of ERβ protein decreased, and the expression of p57kip2 protein increased in ICI182780 group and TAM group, and the difference was statistically significant between ICI182780 group and control group (P<0.05). Compared with the E2 group, the expression of ERβ protein decreased, and the expression of p57kip2 protein increased in E2 + ICI182780 group and E2 + TAM group, and the difference was statistically significant between E2 + ICI182780 group and E2 group (P<0.05). ERa protein of JEC cells did not expressed in experimental group or control group. Conclusion ERa protein are not expressed in JEC cells. ICI182780 have a stronger role in antagonizing estrogen, and may induce the expression of p57kip2 protein by down-regulating the expression of ERβ protein in JEC cells, block the cell cycle progression and inhibit the growth of tumor cells. TAM has a weaker estrogen like effect on the growth of JEC cells. It is possible that combined detection of the expression of ERa and p57kip2 protein in EC has an important reference value for individualized selection of endocrine therapy for EC patients.

Objective To explore the correlation between acute infarctions in different parts of the brain and the risk of vascular cognitive impairment (VCI). Methods 212 patients with acute cerebral infarction were tested using Mini Mental State Examination(MMSE)and Montreal cognitive assessment(MoCA),and were divid-ed into normal cognition group,VCI group,vascular dementia group,and mixed dementia group. We analyzed the gender,age,past medical history,personal history,MMSE and MoCA scores,and imaging data. Results Of the 212 patients,61(28.77%)had normal cognition level,74(34.91%)had VCI,56(26.42%)had vascular demen-tia,and 21(9.91%)had mixed dementia. Multiple regression analysis showed that frontal lobe infarct increased the risk of VCI(OR,41.72)and vascular dementia(OR,48.49);cerebellar infarction also increased the risk of vascular dementia(OR,4.70)and mixed dementia(OR,12.38);and temporal lobe infarction increased the risk of mixed dementia significantly(OR,56.98). Conclusions Approximately 71.3%of the patients with acute cere-bral infarction develop vascular cognitive impairment. The infarcts occurring in the frontal lobe ,temporal lobe and cerebellum increase the risk of VCI significantly ,which should be given interventional therapies.

As the most important nuclear transcription factors in the cells, NF-κB is involved in many intracellular signaling pathways and transcription and regulation of genetic information. The signal transduction pathways mainly include the activation of IκB kinase, degradation of IκB protein and the nuclear translocation of p65. p65 trans-nuclear binding with DNA is the key for NF-κB to play a role. Abnormal activation of NF-κB is a major factor in the induction of oxidative stress, inflammation, cancer and so on. Therefore, maintaining the balance of NF-κB activity and regulating the nuclear translocation of p65 have great significance for further research on related subjects. In this paper, the regulation effects of the main active substances of medicinal plants (such as polyphenols, saponins, and alkaloids) on p65 nuclear translocation and the upstream pathway of NF-κB were discussed, expecting to provide reference for the development of natural active substances for functional food.

Objective To establish a hypothermic pleural effusion model with SD rats,and to observe the relationship between hypothermic pleural effusion production and cold water immersion duration.Methods Sixty male Sprague-Dawley rats of(290.3 ± 7.5) g were randomly divided into experimental group(n =50) and control group(n =10).The experimental group was divided into group A1,A2,A3,A4 and A5 according to the different immersion time with 10 rats in each group.The experimental group was placed in a self-made cylindrical erected rat holders and then immersed in cold water at (20 ±0.2) ℃.The soaking depth was the level of clavicle of the rats.Group A1 and A2 were respectively removed and anesthetized after immersing 12 hours and 24 hours,and the serum and pleural effusion were collected to detect total protein and lactate dehydrogenase concentration.The remaining rats of experimental group were rewarmed by incubating at 37 ℃ for 1 hour.Group A3,A4 and A5 were respectively anesthetized at 12 hours,24 hours and 36 hours after the initiation of rewarming for detecting the serum and pleural effusion.The control group was directly anesthetized to collect serum to detect total protein,lactate dehydrogenase concentration.The pleural effusion quality was analyzed by Light standard.Results There was no obvious pleural effusion in normal rats.The amount of pleural effusion in the group A2 was higher than that in the group A1.After the rewarming,the amount of pleural effusion gradually decreased with the prolongation of time,and disappeared 36 hours later.Pleural effusion total protein/serum total protein was about 50% in group A1,while it was more than 50% in the group A2,A3 and A4.Pleural effusion lactate dehydrogenase/serum lactate dehydrogenase were all less than 60% in each experimental group.The pleural effusion lactate dehydrogenase of experimental group was 2 times greater than that of the control group.Conclusion The method of establishing hypothermia pleural effusion SD rats model by immersing in 20 ℃ water is stable and reliable.The pleural effusion increased with the prolongation of the cold water immersing.After rewarming,the pleural effusion was gradually absorbed and then dispeared.

<p><b>OBJECTIVE</b>To investigate the drug resistance of HIV patients to the HIV-1 CRF01_AE and CRF07_BC strains in Sichuan province during 2010 to 2013.</p><p><b>METHODS</b>1.5 ml of plasma were collected from AIDS patients who had been receiving anti-retroviral treatment for over 6 months but still had a HIV-1 virus load of over 1 000 copies/ml from January 1, 2010 to December 31, 2013 in Sichuan province. Genetic analysis of the HIV-1 pol gene was performed using self-established method, and patients with a positive drug-resistant HIV-1 pol gene mutation were included. HIV-1 poly gene was successfully sequenced for a total of 1 213 patients. Drug resistance of different HIV-1 strains was compared with χ2 test or Fisher exact test.</p><p><b>RESULTS</b>558 cases (46.0%) of the 1 213 successfully sequenced patients were infected by HIV-1-strains with drug-resistant mutations, including 327 cases (58.6%) infected by CRF01_AE strain, 126 (22.6%) by CRF07_BC strain, 46 (8.2%) by CRF08_BC strain, 33 (5.9%) by B strain, 4 (0.7%) by C strain, 1 (0.2%) by CRF02_AG strain, and 21 (3.8%) by unidentified strains. Drug-resistant mutation analysis revealed that L33, F116, L74, Q151, and T69 resistance mutations occurred only in the CRF01_AE strain, while A71, K43, and Q58 resistance mutations occurred only in the CRF07_BC strain; in nuclear nucleoside reverse transcriptase inhibitors (NRTIs) and non nucleoside reverse transcriptase inhibitors (NNRTIs), CRF01_AE subtype strains showed highly resistant rate were higher than CRF07_BC, CRF08_BC and B subtype strains, with the differences were statistically significant (P<0.05).</p><p><b>CONCLUSION</b>The drug-resistant HIV-1 strains in Sichuan mainly included the CRF01_AE and CRF07_BC strains, which had different resistance mutations.</p>
