Objective: To study the relationships among attributional style, self-efficacy and subjective well-being(SWB). Methods: 269 college students participated the study. Attributional Style Questionnaire , Self-efficacy Questionnaire and Subjective Well-being(SWB) Questionnaire were applied to the college students. Results: ① Attributional style predicated SWB, but three dimensions (internality-externality; whole-part; controllability-uncontrollability)of negative events were significant negative predicators of SWB. ② Self-efficacy was a significant positive predicator of SWB. ③ There were no differences in SWB between sexes and specialities. ④ There were significant differences in SWB between students with different self-efficacy levels, and the SWB of high self-efficacy group was better than that of the low self-efficacy group. Conclusion: College students'attributional style and self-efficacy impact their subjective well-being.Educators should cultivate students's positive attributional style and enhance their self-efficacy.

The distribution and morphological characteristics of CA-containing cell bodies of diencephalon in 7-9monthold fetuses were studied by means of Faglu histofluoresccnce method. Although the general distribution of CA cell bodies in the human diencephalon observed in the present study is similar to that in other mammals, there are some significant differences. A great number of CA neurons occur within the lateroventral hypothalamic zone. There are more numerous larger CA neurons distributed outside the periventricular gray in human diencephalon.

The distribution and morphological characteristics of catecholamine(CA)-containing neurons in the human brain stem of 7-9-month-old fetuses were studied by using Faglu histofluorescence method. The distribution of the main CA groups is consistent with the data provided by the literature concerning human infant and adult except for the presence of numerous small premature-looking fluorescent cells in the fetal area postrema which is lacking in the human infant and adult. As compared with most studies of other animals, the CA neurons of the dorsocaudal extension of the locus coeruleus in human appear to be more extensive and do not close to the ependyma of the fourth ventricle. Moreover, the CA neuronal population in human midbrain become more hypertrophic and appear to be more complexly organized in comparison with those in animals.

Objective To provide theoretical and scientific evidences for plague control,through understanding the F1 antibody level distribution and affected factor of population having healed from plague from plague natural focus of Rat.flavipectus in Yunnan Province.Methods The places and population investigated were chosen according to plague surveillant data in Yunnan Province from 1986 to 2005,using caso-control study and quesfionary. All samples were detected by indirect hemagghtination(IHA),including 248 serum samples from population having heaIed from phsue in 23 counties as case group.295 senlm samples from healthy population inoculated with EV vaccine in 7 counties as artificial immunization group, and 235 serum samples from healthy population not inoculated it in a non-plagued foei county as negative comparison group,with the diagnosing standard for positive titor being not less than 1:20.Results(①The difference WSS statistically significant(X2=44.80,P<0.05)between plague and non-plagued foci with F1 antibody positive rates being 22.10%(120/543)and 0(0/235),respectively.② The F1 antibodv positive rate of case group,35.89%(89/248)and geometric mean titer(GMT)1:84,was higher than that of artiIicial immunization group,which was 10.51%(31/295)and with GMT 1:34,respectively,the difference being statistically significant(X2=50.41,P<0.0125);the positive rate of case group wgs hisher than the neganve comparison group,the difference being statistically significant(X2=103.39,P<0.0125):the posifive mte of artificial immunization group was higher than the negative comparison group,the difference being statisticallv significant(X2=26.23,P<0.0125).③The differences were not statistically significant in the F1 antibedy positive rates of case group for age,sex,nation and occupation(X2=1.88,2.01,5.46,0.04,P>0.05).④The difference was not statistically significant in 89 plague patients with positive F1 antibody at the time of onset and rehabilitation(t= 1.23,P>0.05).Conclusions ①Plague FI antibody in people distributes the sanle a8 the plague natural focus of Rat.flavipectus does in Yunnan Province.②For naturally infected plague patients,only 1/3 popuhtion get long- term immunity,and still 2/3 can be infected again.The protecting rate and effect of naturally acquired immunity due to infection of plague are better than amfieially acquired immunity from inoculation of EV vaccine.③For the population having healed from plague,the positive rotes of FI antibody are not affected by age,sex,nation and occupation,however for those whose plague F1 antibody is still positive after some time,the titer will remain or even increase.

Objective To analyze the clinicopathologic characteristics and prognosis in multinodular and multicentric occurrence of hepatocellular carcinoma (HCC). Methods Study group (multinodular HCCs) involved 42 multinodular HCCs patients with a total of 112 HCC nodules. 16 patients with single HCC nodule, and 4 patients with portal vein tumor embolus, 5 normal livers served as controls. MtDNA D-Loop sequences were compared among multinodular lesions in the study group, between inconsecutive tumor tissues and between tumor and embolus tissues in the study group with regard to their clinicopathologic characteristics. Results In study group, for the multinodular HCCs 20 cases were categorized as multicentric occurrence (MO) based on their variant mtDNA D-Loop sequences in each nodule from the same patient. 22 cases were characterized as intrahepatic metastasis (IM) based on the identical sequences found in each nodule from the same patient. In all 20 cases for the rest of the study group (16 patients with single HCC nodule and 4 patients with portal vein tumor embolus), the inconsecutive tumor tissues or the portal vein tumor embolus and original tumors shared identical sequences. HBeAg (P =0. 008), tumor size ( sizes of all nodules) ( P = 0. 029), position of nodules (P = 0. 040), cirrhosis ( P =0. 011 ), portal vein and microscopic tumor embolus ( P = 0. 023 ) and differentiation ( Edmondson grade) of the main nodule (P = 0. 027 ) were significantly different between the IM and MO HCCs, thus were considered to be the important factors in determinning the clonal origin of multinodular HCC. Positive HBeAg, cumulative diameter of all nodules ≤7 cm, nodules located in different lobes, cirrhosis, negative for portal vein or microscope tumor embolus and/or well/moderate differentiation of main nodular histopathology were found in high rate in MO. Tumor-free survival of the MO subjects was significantly longer than that of the IM subjects (21.6 ±4. 2) months vs. (8.7 ±2. 5) months, P =0. 031 ). Similarly, overall survival of the MO subjects was longer than that of the IM subjects (29. 6±4. 7) months vs. ( 14. 6 ±2. 9) months, P = 0. 034). Multivariate analysis revealed that the IM/MO characteristic was an independent factor influencing both tumor-free survival ( P = 0.012 ) and overall survival ( P = 0.011 ).Conclusions HBeAg, tumor size ( sizes of all nodules), position of nodules, cirrhosis, portal vein and microscopic tumor embolus and differentiation of the main nodule are important factors in differentiating IM and MO. Positive HBeAg, cumulative diameter of all nodules ≤ 7 cm, nodules located in different lobes, cirrhosis, negative for portal vein or microscopic tumor embolus and/or well/moderate differentiation of main nodular histopathology are frequent phenomena in MO. MO HCC patients might have a favorable outcome compared with IM patients.

Objective To explore the nursing effect of health education on patients with peptic ulcer. Meth-otis 108 patients with peptic ulcer were randomly divided into 2 groups:intervention group and control group. Each consisted of 54 samples and was given the same medication. Besides, the control group was additionally cared with routine heath education while the intervention group was given the comprehensive health education. Results Com-prehensive health education reduced the course of hospital,alleviated symptoms of digestion and improved the peptic ulcer,while the routine heath education made no significant progress in either aspect. Differenees of knowledge as well as attitude score was of statistical significance(P≤0.05) between before and after heath education were given except the score of behavior ( P > 0.05 ). Conclusion Comprehensive health education could significantly improve curative effect for the treatment of peptic ulcer.

Objective To investigate the protective effect of sodium tanshinone ⅡA sulfonate(STS) on adriamycin-induced H9c2 cell apoptosis. Methods H9c2 cells were divided into four groups: the control group, the ADR group, the STS group, and the AS(ADR+STS) group. MTT assay were used to detect cell proliferation and cell death. The cell cycle of H9c2 cells were determined by flow cytometry assay. Protein expression of Bcl-2, Bax and Caspase-3 was detected by Western blot assay. Results Compared with the control group, cell proliferation was significantly reduced , and the number of the cells was significantly increased in the G0/G1 phase in the ADR group(P < 0.01, P < 0.05). At the same time, the expression of Caspase-3 was dramatically enhanced and the ratio of Bcl-2/Bax was significantly reduced (P < 0.05, P < 0.01) in the ADR group. However, pretreatment of STS increased H9c2 cell proliferation, decreased the number of the arresting cells, inhibited the expression of Caspase-3, and improved the ratio of Bcl-2/Bax (P < 0.05, respectively). Conclusions STS can attenuate ADR-induced myocardial cell apoptosis.

Objective To evaluate the effect of alveolar recruitment maneuver on the perioperative pulmonary function in the morbidly obese patients undergoing laparoscopic sleeve gastrectomy.Methods Forty morbidly obese patients of both sexes,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 18-64 yr,with body mass index ≥ 40 kg/m2,scheduled for elective laparoscopic sleeve gastrectomy,were randomly divided into either control group (group C) or alveolar recruitment maneuver group (group R) using a random number table,with 20 patients in each group.Patients in group C were treated with volume-or pressure-controlled ventilation after creation of pneumoperitoneum,maintaining the peak inspiratory pressure (Ppeak) ≤ 30 cmH2O and partial pressure of end-tidal CO2 35-40 mmHg.Patients in group R received alveolar recruitment maneuver once every 30 min starting from creation of pneumoperitoneum until the end of surgery.Patients were transfered to post-anesthesia care unit (PACU) with endotracheal tube which was extubated when the unified extubation standard was achieved in PACU.The patients who stayed in PACU for 2 h showing no indications for extubation were transfered to intensive care unit for continuous ventilation support.Immediately after intubation,immediately after creation of pneumoperitoneum,at 30,60 and 90 min of pneumoperitoneum,and at the end of pneumoperitoneum,blood samples were collected from the radial artery for blood gas analysis.Immediately after intubation,immediately after creation of pneumoperitoneum,at 30,60 and 90 min of pneumoperitoneum,at the end of surgery,and immediately before discharge from PACU,Ppeak,plateau pressure (Peat),and dynamic lung compliance were recorded.The time for achieving extubation standard and time for achieving the standard for discharge from PACU were recorded.Patients were followed up until discharge,and the feeding time and duration of hospital stay were recorded.Results Compared with group C,PaO2 and oxygenation index were significantly increased at 90 min of pneumoperitoneum,at the end of surgery,and immediately before discharge from PACU,Ppeak was decreased at 60 and 90 min of pneumoperitoneum and immediately after the end of pneumoperitoneum,Pplat was decreased at 60 and 90 min of pneumoperitoneum,the dynamic lung compliance was increased at 30,60 and 90 min of pneumoperitoneum and immediately after the end of pneumoperitoneum,and the time for achieving extubation standard,time for achieving the standard for discharge from PACU,feeding time,and duration of hospital stay were shortened in group R (P＜0.05 or 0.01).In group C,one patient did not present with indications for extubation and were transfered to intensive care unit for continuous ventilation support.Conclusion Intraoperative alveolar recruitment maneuver can effectively improve the intraoperative pulmonary function and promote the recovery of postoperative pulmonary function in the morbidly obese patients undergoing laparoscopic sleeve gastrectomy.

Objective: To observe the therapeutic effect of acupuncture plus psychological intervention for postpartum depression.
Methods: By random number table, 85 patients with postpartum depression were divided into a treatment group and a control group. Forty-three cases in the treatment group were treated by acupuncture plus psychological intervention, once every day, five sessions per week, and rest at weekend. Forty-two cases in the control group were treated by oral administration of Fluoxetine Hydrochloride, 20 mg, once per day. The two groups were treated continuously for six weeks. The change of the score in Hamilton depression scale (HAMD) was observed and the therapeutic effect was summarized.
Results:The total effective rate was 90.7%in the treatment group and 90.5% in the control group. The difference in the total effective rate between two groups was not statistically significant (P>0.05). In the intra-group comparisons of HAMD scores two, four and six weeks after treatment in both groups with those before treatment, the differences were statistically significant (all P<0.05). In comparison between the two groups at the same time point, the differences in HAMD scores were not statistically significant (all P>0.05). Regarding the adverse events, 5 cases had nausea, 3 cases had dizziness, and 6 cases had poor appetite in the control group; no obvious adverse events happened in the treatment group.
Conclusion:Acupuncture plus psychological intervention for postpartum depression is as same as oral administration of Fluoxetine Hydrochloride in therapeutic effects, but it does not have adverse reaction.
