Objective:To clone and express panallergen profilin from the pollen of coco(Cocos nucifera Linnaeus).Methods:RT-PCR and RACE methods were applied to clone the full-length panallergen genes from coco pollen and the sequence was analyzed.The specific primers were designed.The ORF of profilin of coco pollen was amplified with RT-PCR and cloned into the expression vector pET 28a.Expression of the recombinant coco pollen profilin was carried out in E.coli BL21(DE3) and the purification of the recombinant protein was performed via affinity chromatography with Ni2+ coupled to sepharose.IgE reactivity to recombinant coco pollen profilin was investigated by immunoblot.Results:The complete sequence of coco pollen profilin was cloned.The sequence was 608 bp and included an open reading frame(396 bp) coding for 131 amino acids.Sequence analysis showed that the deduced protein was an acidic protein with an estimated molecular mass of 14.19 kD and a pI of 4.61.The GeneBank accession number of the clones was EF173598.After overexpressed in E.coli BL21(DE3),the recombinant protein was purified through affinity chromatography with Ni2+ coupled to sepharose.Immunoassay showed that the recombinant allergen has good IgE binding capacity.Conclusion:The profilin of coco pollen is expressed successfully in BL21(DE3),which will be used as a base for further study on coco pollen related allergy.

Objective To study the incidence and prevalence in the children aged 1-2 years and 1-6 years with cerebral palsy(CP) in Qinghai province,and to identify the epidemiological characteristics and control status of the children with CP.Methods A stratified cluster random sampling method was used to conduct epidemiological survey of 10 000 children in Qinghai province.Children diagnosed as CP were asked to fill in the CP questionnaires,including children's development,and the status of prevention and treatment of CP.Compared with the children diagnosed as CP,4 healthy children at the same age were asked to fill in the questionnaires related to children's development.SPSS 15.0 statistical software was used for data analysis.Results Seven children with CP were diagnosed at the aged 1-2 years,and the total incidence rate was 3.3‰(7/2 148 cases).The incidence between the urban (0) and the rural areas (12‰) (7/582 cases) was significantly different(P =0.000 1),while there was no significant difference statistically between boys (5 cases) and girls (2 cases) (P ＞ 0.05).Fifty-four children with CP were diagnosed at the age of 1-6 years,and the total prevalence rate was 5.4‰(54/10 000 cases).The prevalence between the urban (2.3‰,17/7 348 cases) and the rural areas (13.9‰,37/2 652 cases) was statistically different (x2 =49.144,P ＜ 0.01),while there was no significant difference statistically between boys (31 cases) and girls (23 cases) (P ＞ 0.05).The proportions of various types of CP were as follows:29 cases(53.70％) of spastic type,9 cases(16.67％) of hypotonia,7 cases (12.96％) of mixed type,4 cases (7.41％) of ataxia,3 cases (5.56％) of rigidity and2 cases (3.70％) of dyskinetic,respectively.Among the spastic types,there were 16 cases (55.17％)of spastic quadriplegia,6 cases (20.69％) of spastic hemiplegia,4 cases (13.79 ％) of spastic diplegia,2 cases (6.89 ％) of spastic monoplegia and 1 case (3.45％) of spastic triplegia,respectively.The top three risk factors were premature (13 cases,24.1％),hypoxic-ischemic encephalopathy (9 cases,16.7％) and maternal threatened abortion (8 cases,14.8％).The first three complications were mental retardation,language dysfunction and epilepsy.Conclusions The incidence and prevalence of CP in children in Qinghai province are very high,which is higher in the rural areas than that in the urban areas.The most common CP is spastic type.The main risk factors for CP are preterm labor,hypoxic-ischemic encephalopathy and maternal threatened abortion.Intellectual disability,speech disability and epilepsy are the most common complications of CP.Maternal and perinatal infant health care and early intervention need to be further strengthened.

Objective To investigate the proportion changes of the CD4 + CD25 + T cells and CD8 + CD28 - T cells in the peripheral blood of gastric cancer patients. Methods The proportions of CD4 + CD25 + T cells and CD8 + CD28 - T cells in the peripheral blood of gastric cancer patients were determined by flow cytometry. 30 patients with gastric cancer and 30 patients with chronic gastritis were enrolled in this study. Results Compared with the chronic gastritis controls, the proportion of the CD4 + CD25 + T cells in the peripheral blood of patients with gastric cancer (8.7%±1.3%) was not significantly changed. But the proportion of the CD8 + CD28 - T cell in the peripheral blood of patients with gastric cancer (30.3%±3.3%) was significantly higher than that of control group (20.3%±2.7%), P<0.05. There was no significant association between the proportions of T regulatory cells and the lymphomatic metastasis of gastric cancer. No relation was found between the proportions of T regulatory cells and pathological types of gastric cancer. Conclusion CD8 + CD28 - T ceils in peripheral blood may be of some value in the progression of gastric cancer.

Objective To observe the effect of health education on the mental health and life quality of people at high risk of stroke.Methods Totally 3092 residents of Wuhan aged over 40 were screened for stroke risk.Of those,392 cases were assessed as at high risk of stroke and were chosen as the study's subjects.They were given a 1-year course of standard health education.Before and after the intervention,their diet,exercise,compliance with medication and smoking habits were recorded.They were also assessed using the self-rating depression scale (SDS),the self-rating anxiety scale (SAS) and the Spitzer quality of life index (QLI).Results Significant improvement in healthy behavior was observed after the intervention.The average SDS score and SAS score had decreased significantly,and the average QLI score was significantly higher than before the intervention.Conclusion Health education can improve the healthy behavior,mental state and life quality of people at high risk of stroke.

ObjectiveTo know about the correlation analysis of the physical and mental status of organ transplanted patients' family members during the patients' rehabilitation period and the long term survival of the transplanted organs.MethodsA total of 600 organ transplanted patients' family members were investigated by Zung self-rating anxiety scale (SAS) and simple coping style questionnaire.The results underwent subsequent analysis.ResultsAnxious state of organ transplanted patients' family members was more severe than that of domestic norm (P<0.01).There were some differences in terms of anxious state of family members with different genders,education backgrounds,income and the resource of medical expenditure (P<0.05).Family members most took positive coping styles,whereas fewer adopted negative coping styles (P<0.01).Positive coping styles were negatively correlated with the anxiety of family members (P<0.01) and positively correlated with long term survival of transplanted organ(P<0.05).However,negative coping styles of family members were significantly positively correlated with their anxiety (P<0.05) and were negatively correlated with long term survival of transplanted organ.ConclusionsThe anxiety generally exists in organ transplanted patients' family members.There are differences in terms of anxious state among family members of different genders,different education backgrounds,income or with the resource of medical expenditure.The more they adopt positive coping styles,the lower anxiety level they show and the longer the transplanted organ survive.Conversely,the more they adopt negative coping styles,the higher anxious level they show and the shorter the transplanted organ survive.

OBJECTIVETo evaluate the differences in the autophagy activity of alveolar macrophages between patients with different stages of coal workers' pneumoconiosis (CWP).

METHODSA total of 116 coal workers were investigated in the field. Their lung lavage fluid was collected and purified to obtain alveolar macrophages. The morphological characteristics of autophagy were observed by transmission electron microscopy. The expression of autophagy marker (LC3) and autophagy regulators (Beclin1, mTOR, and p-mTOR) was measured by Western blot. The autophagy activity of alveolar macrophages was compared between dust-exposed subjects and patients with stage I, II, and III CWP.

RESULTSThe autophagy activity of alveolar macrophages differed between patients with different stages of CWP, according to transmission electron microscopy. Patients with stage II CWP had significantly higher protein expression of LC3 II/I and Beclin1 in pulmonary macrophages than those with stage ICWP (P < 0.05); patients with stage III CWP had significantly lower protein expression of LC3 II/I and Beclin1 in pulmonary macrophages than those with stage II CWP (P < 0.05), but had significantly higher protein expression of LC3 II/I and Beclin1 than those with stage I CWP (P < 0.05); patients with stage II CWP had a significantly higher protein expression of Beclin1 than the dust-exposed subjects (P < 0.05). Patients with stage II CWP had significantly lower expression of mTOR and p-mTOR in pulmonary macrophages than the dust-exposed subjects and those with stage I CWP (P < 0.05), while patients with stage III CWP had significantly higher expression of mTOR and p-mTOR than those with stage II CWP (P < 0.05).

CONCLUSIONThe autophagy activity of alveolar macrophages varies between patients with different stages of CWP.

Objective To evaluate the effect of transcutaneous neuromuscular electrical stimulation on prevention of intensive care unit-acquired weakness (ICU-AW) in chronic obstructive pulmonary disease (COPD) patients with mechanical ventilation. Methods A prospective randomized controlled study was conducted. Sixty COPD patients aged 18-85 years old who were accepted mechanical ventilation therapy admitted to general intensive care unit (ICU) of the First Affiliated Hospital of Hunan University of Medicine from October 2017 to October 2018 were enrolled. Patients were divided into control group (n = 30) and intervention group (n = 30) by random number table method. All patients were accepted routine treatment, and on this basis, the intervention group was applied transcutaneous neuromuscular electrical stimulation on the extremities (twice a day, 30 minutes each time) after 24 hours of admission until ICU discharge. The Medical Research Council muscle strength score (MRC-Score), grip strength, incidence of ICU-AW on the 7th day after admission and on the day of ICU discharge; modified Barthel index score on the day of ICU discharge; and duration of mechanical ventilation, the length of ICU stay, and the length of hospital stay were compared between the two groups. Results Twenty-nine and 27 patients in the control group and the intervention group respectively finally completed the study in dividually. There was no significant difference in gender, age, Barthel index score before 2 weeks of ICU admission, body mass index or acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) in ICU between the two groups. There was no significant difference in the MRC-Score, grip strength or incidence of ICU-AW on the 7th day after ICU admission between the two groups. Compared to the control group, the MRC-Score, grip strength and Barthel index score in the intervention group were significantly increased [MRC-Score: 55.97±8.43 vs. 46.32±7.36, grip strength (kg): 33.46±11.62 vs. 27.42±9.64, Barthel index score:46.04±5.46 vs. 42.13±3.32, all P < 0.05], the incidence rate of ICU-AW was significantly decreased [7.4% (2/27) vs. 31.0% (9/29), P < 0.05], and duration of mechanical ventilation, the length of ICU stay, the length of hospital stay were significantly shortened [duration of mechanical ventilation (days): 5.12±2.01 vs. 7.24±4.35, the length of ICU stay (days): 8.34±2.36 vs. 10.45±2.62, the length of hospital stay (days): 13.21±2.21 vs. 15.38±3.67, all P < 0.05]. Conclusion Transcutaneous neuromuscular electrical stimulation can effectively improve the muscle strength of COPD patients with mechanical ventilation and reduce the incidence of ICU-AW.

OBJECTIVETo investigate psychological stress and influence factors on the mine emergency rescue personnel.

METHOD564 mine emergency rescue personnel from a rescue group were select as subjects, and 60 designers from a steel design institute were as controls. Self-made questionnaire and general job stress questionnaire were used to investigate the basic information, rescue history, psychosomatic symptoms, depression symptoms, daily job stress and negative emotions of emergency rescue personnel. SPSS17.0 software was used to analysis the psychological stress on the mine rescue personnel and its influence factors.

RESULTSThe detection rate (41.94%) of depression symptoms in rescue team was higher than that of controls (24.90%). The score of daily job stress was higher than that of logistical support. The older age group with higher negative emotional and daily job stress than the younger. The highest negative emotion was in age group of more than 40 years old. The highest score of daily job stress was in ≤30 years old. The score of depression and psychosomatic symptoms were higher than those of the college and the above. The scores of depression in group of duration of rescue <10 years was higher than that of duration≥10 years. The score of daily job stress is the lowest in rescue for 1 to 2 times per year and the highest in group of simulation training once a week. The score of daily job stress and depressive symptoms were getting higher with the extension of combat duty time. Age, hours of combat duty, training times a week, education and life events were the main affecting fectors on mental health of mine rescuers.

CONCLUSIONSMine rescuers have more psychological stress than generic population. The psychological stress of the mine crew is related to age, education, life events, training and combat readiness duty time.
