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.

The acupoint selection was retrieved from the ancient and modern literature on the treatment of sub-healthy condition with acupuncture. The law of acupoint application was analyzed so as to provide a certain reference to the determination of acupoint prescription in clinical acupuncture. The ancient literature was retrieved from Chinese basic ancient literature database. The modern literature was retrieved from Cochrane Library, Medline, PubMed, Ovid evidence-based medicine database, Chinese biomedical literature database, China journal full-text database, VIP journal full-text database and Wanfang database. The database mining software was adopted to explore the law of acupoint application in treatment of sub-healthy conditions with ancient and modern acupuncture. The acupoint use frequency, compatibility association rule, law for meridian use and the use regularity of specific points were analyzed. In the ancient treatment for sub-healthy condition, the top five commonly used acupoints are Shenmen (HT 7), Zhaohai (KI 6), Taibai (SP 3), Daling (PC 7) and Taixi (KI 3). The most commonly combined points are Zhangmen (LR 13), Taibai (SP 3) and Zhaohai (KI 6). The most commonly used meridians are the bladder meridian of foot-taiyang, kidney meridian of foot-shaoyin and liver meridian of foot-jueyin. The most commonly used specific points are the five-shu points. The most commonly used acupoints are located in the lower limbs. In the modern treatment, the top five commonly used acupoints are Zusanli (ST 36), Sanyinjiao (SP 6), Baihui (GV 20), Shenshu (BL 23) and Guanyuan (CV 4). The most commonly supplemented points are Hegu (LI 4) and Taichong (LR 3). The most commonly used meridians are the bladder meridian of foot-taiyang, the conception vessel and the governor vessel. The most commonly used specific points are the back-shu points. The most commonly used acupoints are located in the lower limbs. After the systematic comprehension of the relevant ancient and modern literature, the most commonly used acupoints are selected along the bladder meridian of foot-taiyang, and the most commonly used specific points are the back-shu points, the five-shu points and the front-mu-points. the acupoints are mostly located in the lower limbs.

Objective To discover the reciprocal regulation and its molecular mechanism of estro-gen, IL-6 and IL-8 in ovarian cancer cells. Methods Based on our previous studies, the effect of 17β-estradiol (E2) on the expression levels of IL-6, IL-8 and their respective receptors was investigated. Mean-while, the effect of IL-6/IL-8 on estrogen receptor (ER) expression and estrogen-dependent transcriptional activation was analyzed. Gene expression profile analysis revealed that CAOV-3 and OVCAR-3 cells, which express ER, IL-6 and IL-8 receptors, were suitable models for this study. Results We found that E2 not only enhanced IL-6/IL-8 secretion via NF-κB signaling pathway, but also modulated IL-6 and IL-8 receptors expression. Tamoxifen (Txf), an ER antagonist, completely abolished E2-stimulated IL-6/IL-8 expression. On the other hand, in the absence of estrogen, both cytokines increased ERα expression, decreased ERβ ex-pression, and activated estrogen-dependent transcriptional activation, which was completely blocked by Txf. Pretreatment of OVCAR-3 with p38 MAPK, MEK1/2 or ErbB2 MAPK inhihitors, respectively, IL-6-media-ted ER activation was blocked, while IL-8-indueed ER activation was blocked by Src inhibitor. Conclusion These data suggest that estrogen, IL-6 and IL-8 may form a mutual amplifying signaling which contributes to the growth and development of ovarian carcinoma.

Objective To explore the relationship between skin photo reactions and structural pa-rameters. Methods Benzophenone-1, Benzophenone-2 and Benzophenone-3 were assessed by phototoxici-ty test and photoallergic test on guinea pig. And the phototoxicity index and photoallergic index were cal-culated after clinical assessment. Structural parameters of the three sunscreens like total energy, binding energy, electronic energy, heat of formation, dipole and sum of the net charges were also calculated by the soft of HyperChem7.0, respectively. Results The phototoxicity index rised with total energy, elec-tronic energy and sum of net charges increasing. And the photoallergy index rised only with binding ener-gy increasing. So there was some correlation between phototoxicity index and total energy, electronic en-ergy and sum of net charges (P<0.01). Significant relationship was only between the photoallergy index and binding energy (P<0.01). Conclusions The phototoxicity is correlated with total energy and e-lectronic energy, while photoallergy is related to binding energy. It is possible to establish a model evalua-ting the safety and structural parameters of benzophenone ramifications.

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 observe the alteration of skin complexion after UVA and UVB exposure.Methods The back skin of ten females with skin type Ⅲ was subjected to single exposure to solar-simulated UVA of double minimal persistent pigment darkening (MPPD) or UVB of double minimal erythema dose (MED). Skin reflectance was assessed with clinical grading, spectcolometer and Mexameter MX 18 before irra-diation, 6 hours, 1, 7 and 14 days after the irradiation. Results After UVB irradiation, a~* value and erythema index (EI) abruptly increased at 6 hours and peaked on day 2; L~* value sharply declined on day 1; ITA° markedly decreased on day 7; melanin index (MI) declined within the first 2 days, but notably increased on day 7. After UVA irradiation, a~* and El value experienced no apparent changes; L~* value obviously declined at 6 hours; ITA° reached its lowest value on day 14; MI increased only on day 1. Conclusions There is a significant difference in the kinetics and extent of skin complexion changes after UVA and UVB irradiation. EI and a~* value are sensitive and accurate indices for evaluating sunburn, and MI and ITA ° for analyzing tanning.
