BACKGROUND: The training task for aircrew of army airmen is very heavy, the evaluation of flight personnel on psychological diathesis is performed to early discover and deal with corresponding questions.OBJECTIVE: To compare the difference of mental health between aircrew and ground crew of army airmen and provide reference data for implementing corresponding norms.DESIGN: Chester sampling investigation and paired design were applied.SETTING: the 71687 Force of Chinese PLA, the 71521 Force of Chinese PLA, Department of Epidemiology, Fourth Military Medical University of Chinese PLAPARTICIPANTS: By chester sampling, 122 aircrew and 122 ground crew of one army airmen in one stationed training troop were randomized in February 2001. The pairs were made at ratio of 1:1 according to age difference less than 3 years and same sex and nationality. The investigated persons were all male, of Han and aged varied from 23 to 52 years.METHODS: Cornell health questionnaire was adopted respectively in investigation of aircrew and ground crew of army airmen. The investigated persons finished and handed in questionnaire independently on the spot in manner of secretion and centralized filling-up. Cornell health questionnaire is composed of 18 sections, including 195 questions, involving 4 aspects,named somatic symptoms, medial and family history, general health and habit and mental symptoms. The total score of Cornell health questionnaire ≥ 30 indicates somatic and mental disturbance and the score of mental section ≥ 10 indicates mental disturbance, both of which are taken as the criteria in comparison of psychological health in receptors of two groups.MAIN OUTCOME MEASURES: Every factor score and total score in somatic and mental sections in Cornell health questionnaire for aircrew and ground crew.RESULTS: The tested results of each 122 cases in either aircrew group or ground crew group entered result analysis. Evaluated results of somatic and mental symptoms in receptors of two groups: the total score was low in Cornell health questionnaire (0-14 scores), of which, the total score in aircrew group was higher than that in ground crew group (81.5% and 59.8%,P ＜ 0.05); the score in mental section was low (0-9 scores), of which, that in aircrew group was higher remarkably than that in ground crew group (99.2% and 91.8%, P ＜ 0.01); the score for the receptors with somatic and mental disturbance (total score≥30, score in mental section ≥ 10) in aircrew group was lower than those in ground crew group (4.1% and 12.3%, P ＜ 0.05); the score for the receptors with mental disturbance (score in mental section≥ 10) in aircrew group was lower remarkably than ground crew group (0.8% and 8.2%, P ＜ 0.01). For somatic section in aircrew group, except the factors of muscle, skeleton and skin, their scores were higher than those in ground crew group (P ＞ 0.05), the scores of the rest factors were all lower than those in ground crew group, of which, the difference was significant in evaluation of factors of eye, ear, nervous system, urinary reproductive system and fatigue in comparison of two groups (P ＜ 0.05). The score of every factor in mental section of aircrew group was lower than those in ground crew group. Except tension factor, in comparison of the rest factors in two groups, the significant difference was present (P ＜ 0.05).CONCLUSION: Overall psychological health state in Cornell questionnaire of aircrew in army airmen was superior to ground crew. Aircrew still presents a part of psychological health questions, mainly in somatic section and inadaptability was the most positive response in mental section, suggesting that aircrew probably presents inadaptable phenomena.

Objective:To evaluate the clinical efficacy of hydrotherapy in the treatment of children with spastic cerebral palsy (CP).Methods:The China National Knowledge Infrastructure, Wanfang databases, CQVIP databases, PubMed and the Cochrane library were electronically searched for reports published before November 2018 of randomized and controlled trials (RCTs) of hydrotherapy for treating children with spastic CP. Two researchers screened the literature independently, extracted data and assessed the risk of bias in the included studies. The meta-analysis was performed using version 5.3 of the RevMan software.Results:A total of 6 RCTs were included, covering 464 patients. It was found that hydrotherapy combined with conventional rehabilitation was significantly more effective than conventional rehabilitation alone.Conclusions:It has been proved that hydrotherapy can improve the symptoms of children with spastic CP, relieve their spasticity and promote better motor function.

Objective To investigate the relation between the expression of MICA/B in lung cancer cells and the mediastinum lymph node metastasis. Methods The samples of the lung cancer tissue as test group and the healthy tissue beside lung cancer as control group from 30 cases of patients with lung cancer were collected, and the expression of MICA/B on lung cancer cells surface were detected by flow cytometry.All patients were divided into three groups(N0, N1, N2) according to the state of lymph node metastasis, and the expression of MICA/B was analyzed among the three groups. Results The expression level of MICA/B in test group was significantly higher than that in control group[(0.3788±0.2398) %, (0.1908±0.1760) %] (P ＜0.01),however the MICA/B expression level between N0 and N1 or between N1 and N2 was not statistically different (P＞0.05), while that between N0 and N2 had statistical difference (P＜0.05). Conclusion The expression level of MICA/B on surface of lung cancer cells is high, and the MICA/B as ligand of NKG2D may play an important role in the tumor immune response. The expression of MICA/B in mediastinum metastatic lymph node from lung cancer is remarkably increased and the prognosis of patients with lymph node metastasis is poor. MICA/B could be considered as a marker of mediastinum lymph node metastasis.

Objective To investigate the change of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the skin of diabetic rats, and to explore the potential role of MMP-9/TIMP-1. Methods Diabetic rats were induced with streptozotocin (STZ). Then all rats were maintained for 6 weeks. Routine pathological examination and immnnohistochemistry were made to reveal the histological and cytological appearances. RT-PCR and Western blotting were used to detect the expression of mRNA and protein of MMP-9 and TIMP-1 in the skin. Results Six weeks after STZ treatment, examination of HE-stained skin sections from normal and diabetic animals revealed that the epidermis and dermis layers were thinner in diabetic rats than those in control rats. The skin of diabetic rats showed features of atrophy such as disorganization of connective tissue fiber bundles and enlarged space between collagen fiber bundles. In contrast, thick bundles of connective tissue were observed in the dermis of normal rat skin. In normal skin, cells had a bipolar, spindle-shaped appearance in the thick collagen bundles, while in the skin of diabetic animals the interstitial cells had a rounded, shrunken and crenated appearance. The relative values of expression of MMP-9 in diabetic group were higher than those in normal group with significant difference, however, the relative values of expression of TIMP-I in diabetic group were lower than those in control group. Conclusion The changes in cutaneous histology and cytology appear earlier than skin wound. These "underlying disorders" may be associated with the imbalance of MMP-9/TIMP-1.

The facile and efficient synthetic route for Ag dendritic nanostructures on Indium tin oxide ( ITO) via electrodeposition was reported. The results showed that the Raman intensities of rhodamine 6G ( R6G) decreased with decreasing the loading concentration, and even at a low concentration of 10-10 mol/L, the signatures of R6G in Raman spectrum were still clearly observed. It indicated that the Ag dendritic nanostructures exhibited high surface-enhanced Raman scattering ( SERS) sensitivity. Moreover, the relative standard deviation ( RSD ) of band at 610 cm-1 was calculated to be 12 . 1%, 12 . 0%, 11 . 7%, 10 . 9%, 13. 2% and 14. 3%, respectively, corresponding with the concentration of R6G from 10-5 mol/L to 10-10 mol/L, which revealed that the Ag dendritic nanostructures could provide abundant hot spots and exhibited excellent reproducibility. In addition, the SERS spectrum of 3-mercaptopropionic acid (3MPA) also could be detected when its concentration was 10-5 mol/L. This method offers an easy and low-cost way to prepare Ag dendritic substrates and makes SERS detection more practicable.
