Objective To perform an evaluation on psychological sub-health of officers and soldiers relieving in major earthquake on May 12th in Wenchuan and explore their rehabilitations.Methods The officers and soldiers relieving in major earthquake on May 12th in Wenchuan were tested by SCL-90. According to the survey results, we implemented corresponding measures of rehabilitation on them. After 10 and 20 days of rehabilitation, we carried out re-evaluation and analysis of the above assessment. Results The officers and soldiers relieving in major earthquake on May 12th in Wenchuan appeared varying degrees of somatization, anxiety, and depressive symptoms. Before psychological intervention, the incidence rate ofsomatization, anxiety and depression were 29.00％, 18.18％ and 10.82％, respectively; the incidence rates of psychological symptoms on the 10th d of psychological intervention (19.58％, 10.41％ and 5.41％) were significantly declined as compared with those before the intervention (x2=5.695, P=0.017; x2=5.630, P=0.018; x2=4.638, P=0.031); the incidenee rates of psychological symptoms on the 20th d of psychological intervention (4.01％, 2.81％ and 0.8％) were obviously decreased as compared with those before the intervention (x2=55.556, P=0.000; x2=30.509, P=0.000; x2=22.660, P=0.000). Conclusion Some of the officers and soldiers relieving in major earthquake on May 12th in Wenchuan may appear varying degrees of psychological problems. The promptly rehabilitation could reduce or eliminate the psychological sub-health state of these rescue workers.

In the areas of prevention and life skills counseling for breast cancer, risk assessment and prediction can assist clinicians to decide if chemoprevention or prophylactic surgery is needed or suggestions on improving the quality of life for their clients. Several mathematical models, namely Gail Model, Claus Model, BRCAPRO Model and Cuzick-Tyrer Model etc. have been developed to make predictions, clinically. This paper has reviewed the development, operation, advantage versus disadvantage and areas of application for the four models. Having family history of breast cancer, one subject was calculated on the risks by the four models and different results were found. Up to 45 years old, the accumulative risks from the four models and population risk were 1.9%, 11.8%, 2.5%, 5.0% and i.6%, respectively. To 75 years old, they were 20.2%,32.5%, 13.1%, 25.0% and 8.5%, respectively. The subject had a relatively high breast cancer risk during her lifetime. A new model is supposed to include a variety of important risk factors and to be validated by large scale of case-control samples. Incidence of breast cancer in China had significantly increased during the last ten years, but the research on developing assessment methods of breast cancer risk had never been reported, suggesting that the development of models for Chinese population is necessary.

OBJECTIVECompletion pneumonectomy (CP) is widely known to be associated with a high morbidity and mortality. However, in certain instances, CP offers the only chance for a cure. Now to explore the indications, prevention and management of complications as well as late outcomes of CP.

METHODSDuring a period of 21 years from January 1985 to August 2006, 24 patients received CP, representing 2.3% of 1026 patients who had undergone pneumonectomy in the same period. There were 17 right and 7 left CPs done in 20 male and 4 female patients with an average age of 58 years (range from 42 to 67 years). Lung malignancy accounted for 22 of these cases in which the indication included local recurrence in 18, second primary tumors in 2 and primary malignancies that developed after right upper lobectomies for pulmonary tuberculoma and pulmonary cyst respectively in 2 cases. Benign disease was progression or recurrence of bronchiectasis in 2 cases. Before CP, 17 patients had had a lobectomy, 5 a bilobectomy, 1 sleeve lobectomy and 1 wedge resection. There were 16 of 20 lung cancer patients receiving postoperative chemotherapy and 3 with positive residues having radiotherapy. The mean interval between the two procedures was 65 months for the whole group (5.5-360) and 32 months for lung cancer patients (5.5-120). They all underwent CP, included sleeve CP in 1 patient.

RESULTSFor all patients, the previous thoracotomy incision was reopened and maneuvers such as rib resection, intrapericardial blood vessel ligation, division of the bronchus first, local application of glues and hemostatic agents, and bronchial reinforcement were routinely used. Intrapericardial route was used in 10 patients (41.7%). Two patients had right pulmonary artery injured. The operation lasted 4-7 hours, with blood loss of 300 to 3000 ml. Overall respectability, morbidity and hospital mortality were 95.8%, 29.2% and 4.2%. No intraoperative deaths occurred. There was 1 early postoperative death after 40 days from adult respiratory distress syndrome. There was no occurrence of bronchopleural fistula, and the 25% associated morbidity rate was a result of bleeding necessitating reexploration in 1 case, chronic empyema in 1 case, arrhythmia in 1 case, anemia in 1 case and fever of unknown reason in 2 cases. Actuarial 1-, 3-, 5-year survival rates from the time of completion pneumonectomy for patients with lung cancer were 77.3%, 50.0% and 29.4%. And 1-, 3-, 5-year survival rates for patients with recurrent lung cancer were 72.2%, 47.1% and 29.4%.

CONCLUSIONSCP can be performed with an acceptable operative mortality and morbidity rate in selected patients. For patients with local recurrence, first and second primary bronchogenic carcinoma as well as benign pulmonary disease, treatment should be surgical when a less invasive procedure is not available and the patients are in good health. In addition, patients undergoing CP have a reasonable prospect for long-term survival.

Objective To investigate the characteristics and distribution of human eehinococcosis in Hobukesar Mongolian Autonomous County (HMAC) in Xinjiang. Methods Using cluster sampling methods, the 2 counties (Tiebukenwusa and Narenhebuke) in HMAC were chosen as focusing areas for investigation. A survey of human echinococcosis including questionnaire, serological test and abdominal ultrasonic scan was carried out. Results The prevalence of human echinococcosis was 9.0% (64/712) by ultrasound and surgical history, including 8.7% (62/712) for cystic eehinococcosis(CE), 0.3%(2/712) for alveolar echinococcosis(AE) and 15.6%(111/712) for total of serological positives in HMAC. CE prevalence rate of different occupations, age, family slaughtering livestock and drinking water source had significant differences(P<0.05). Herdsmen as the highest risk group showed a CE prevalence of the 13.4% (27/201) in comparison with other occupations. The ages between 20 to<40 year-old were at the highest risk stage with 12.8% incidence. But CE prevalence rate of different gender, ethnic and education groups had not significant differences(P>0.05). Conclusions HMAC could be considered as a high endemic human CE region in Xinjiang. The current study reported the main risk factors may include occupations, age difference and drinking water source.

OBJECTIVETo study the effect of qingxin kaiqiao formula and saponin on the learning and memory ability and the expression of the apoptosis signal transducers Abeta and betaAPP in AD rat brain.

METHODThe comparative observation method was adopted for the animal test. Forty male SD rats were randomly divided into five groups, namely the normal group, the model group, the aricept group, the qingxin kaiqiao formula group and the saponin group, with eight rats in each group. Abeta(25-35) (10 g x L(-1)) was injected into their bilateral amygdala to establish the AD rat model. Since the next day, they were intragastrically administered with Aricept (1.67 mg x kg(-1)), Qingxin Kaiqiao decoction (12.67 mL x kg(-1)), saponin (6.30 mg x kg(-1)) and double distilled water filling for 2 weeks to observe their spatial memory ability in a Morris water maze and study the expression of Caspase-3, Abeta and betaAPP in brain tissues by immunohistochemistry.

RESULTEach traditional Chinese medicine groups showed significant improvement in the learning and memory ability of AD rats and notable differences (P < 0.05, P < 0.01) compared with the control group. The qingxin kaiqiao formula group and the saponin group showed a decrease in the expressions of Caspase-3, Abeta and betaAPP in cerebral cortex and hippocampus area, displaying notable differences (P < 0.01, P < 0.05) compared with the control group.

CONCLUSIONqingxin kaiqiao formula and saponin can obviously improve the learning and memory ability of AD rats with by decreasing the expression of Caspase-3, Abeta and betaAPP in cortex and hippocampus.
