Objective: To observe influence of sensation of uncertainty in illness on curative effect of two-week rehabilitation program in patients with acute myocardial infarction (AMI). Methods: A total of 85 AMI patients recently treated in our hospital were selected continuously. They received two-week rehabilitation program treatment and were assessed by Missals uncertainty in illness scale (MUIS). According to MUIS scores, AMI patients were divided into middle-high score group (74.8~117.4 scores, n=51) and low score group (32~74.7 scores, n=34), and they were compared with 43 patients with coronary heart disease (CHD) angina pectoris (CHD control group) received treatment in the same period. Results: Compared with CHD control group, there were significant increase in each dimension score and total score of MUIS [total score (60.61±12.42) scores vs. (78.34±15.20) scores]in AMI patients (P<0.05~0.01). The exercise peak heart rate of MUIS middle-high score group was significantly higher than that of low score group [(137.80±26.49) times/min vs. (126.12±20.51) times/min, P<0.01]. Compared with low score group, there were significant decrease in total scores of activity of daily living (ADL) scale [(84.15±16.38) scores vs. (73.92±14.21) scores] and the 36-item short-form general heath survey [SF-36, (45.22±6.86) scores vs. (37.95±6.43) scores], and significant increase in total score of symptom checklist (SCL)-90 [(138.35±36.47) scores vs. (151.87±42.61) scores], mean days in CCU [(2.53±0.26)d vs. (2.77±0.29)d], mean days on bed [(4.46±0.25)d vs. (5.38±1.22)d], mean hospital day [(20.48±3.16)d vs. (25.37±3.82)d] and mean inpatient fee [(39.1±8.2) thousand RMB vs. (45.7±9.3) thousand RMB] in middle-high score group, P<0.05~0.01. Conclusion: There is significant sensation of uncertainty in illness in patients with acute myocardial infarction, and it makes curative effect of two-week rehabilitation program significantly decrease.

OBJECTIVEThis study investigates the effect of temporomandibular joint osteoarthritis (TMJOA) on different stages of condylar three-dimensional position and provides a theoretical basis for clinical application.

METHODSThe cone beam computed tomography (CBCT) images of 108 TMJOA patients were analyzed and divided into four stages based on the stage standard of osteoarthrosis X-ray performance proposed by Xuchen Ma in 2005. A total of 28 defect-free temporomandibular joint disorders were used as the control group. Differences in condylar position and condylar axis horizontal angle were evaluated and compared.

RESULTSNo significant differences were found in terms of sagittal relationship, but condylar axis horizontal angle showed a significant difference (F = 3.872, P = 0.005). The horizontal angle values of stage 1 in the TMJOA group were lower than those in stages 2 and 3 (P = 0.027, P = 0.000), whereas the horizontal angle values of stage 2 and control groups were lower than those of stage 3 group (P = 0.004, P = 0.047).

CONCLUSIONCondylar horizontal angle differed in each stage of TMJOA, but no significant difference between the parasagittal positions of the condyles was observed in each stage.

Objective To explore the clinical efficacy of NEOVEIL in postoperative pulmonary air leakage of pulmonary bullae resection by video-assisted thoracic surgery. Methods We retrospectively analyzed clinical data of 37 cases received NEOVEIL combined with ATB45 in video-assisted thoracic surgery (the NEOVEIL group), and clinical data of 40 cases by ATB45 alone(the control group) . We compared postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary infection in the two groups. Results There was no postoperative mechanical ventilation,hemothorax and death. In the NEOVEIL group, the postoperative hospitalization time was 5 to 9 days, the postoperative keeping time of pleural cavity tubes 2 to 4 days, the postoperative pulmonary leakage time 0 to 2 days with 4 patients un-leakage, and 1 patients with pulmonary infection; whereas the postoperative hospitalization time was 6 to 10 days,the postoperative keeping time of pleural cavity tubes 3 to 6 days,the postoperative pulmonary leakage time 2 to 5 days and 8 patients with pulmonary infection in the control group. There was statistical significance in the postoperative hospitalization time, keeping time of pleural cavity tubes, the pulmonary leakage time and the incidence of pulmonary inflammation in two groups(P ＜ 0. 05). The incidence of pulmonary inflammation of the NEOVEIL group (2. 7%) was significantly lower than that of the control group(20. 0%)(x2 = 4. 02, P ＜ 0. 05). Conclusion The operative effectiveness of the NEOVEIL group is better than that of the control group. The NEOVEIL can prevent the postoperative pulmonary leakage.

Objective To evaluate skin barrier function in patients with atopic dermatitis (AD),and to assess its relationship with claudin-1 expression.Methods Totally,11 patients with AD and 11 healthy human controls were recruited in this study.A Tewameter TM210 was used to measure transepidermal water loss (TEWL) value,and high-frequency ultrasound to determine epidermal thickness and density,in lesional and non-lesional skin of the patients and normal skin of the healthy controls.A double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) was performed to determine the serum level of free claudin-1 in these subjects.One-way analysis of variance and t test were carried out to compare these parameters in different groups,and Pearson's correlation analysis to estimate the relationship between different parameters.Results The TEWL value was significantly higher in lesional skin than in nonlesional skin of patients with AD and normal skin of the healthy controls ((36.9 ± 34.2) vs.(9.1 ± 6.0) and (4.4 ± 3.1) g·m-2·h-1,both P＜ 0.05).The epidermal thickness in AD lesions was (0.23 ± 0.04) mm,significantly higher than that in nonlesional skin ((0.18 ± 0.03) mm,P ＜ 0.01) and normal control skin ((0.18 ± 0.02) mm,P ＜ 0.01).Ultrasound images revealed a characteristic subepidermal low echo-genic band in the AD lesions.The patients with AD showed a significantly lower serum level of claudin-1 compared with the healthy controls ((0.80 ± 0.88) vs.(1.73 ± 1.85) μg/L,P ＜ 0.05).Moreover,the serum level of claudin-1 was negatively correlated with epidermal thickness (r =-0.61,P ＜ 0.01),but positively correlated with the inverse of TEWL (1/TEWL,r =0.44,P ＜ 0.05).Conclusions The impaired skin barrier function,which may be evaluated by TEWL,1/TEWL and epidermal thickness,is associated with the expression of claudin-1 in patients with AD.
