To explore the theoretical basis of the heretability of servicemen's personalities and to provide references for the development of a set of scientific and effective psychological interventions, 1 306 servicemen were subjected to the 16-PF inventory questionaire and polymerase chain reaction (PCR) examination of angiotensin. The results showed that there was a significant correlation between the scores of self-will, social boldness, self-reliance, and self-restraint in the female servicemen, and the scores of self-will, boldness, self-reliance, emotional stability, and openness in the male servicemen were significantly correlated with the DD genotype of the ACE gene. The results suggested that the determination of the DD genotype of the ACE gene could be used as a useful tool in the research of heretability of personality factors.

To explore the effects of psychological behavior training on the physical stress level of submariners, 42 submariners were divided into two groups, namely experimental group and control group. The submariners in the former group received psychological behavior training for one week. The level of physical stress was determined after being asked to creep through water-filled torpedo launching tube before and after training. The results showed that the changes in physical stress level of subjects in the experimental group were significantly smaller than that of the control group(t=-3.421～-2.415, P

Objective To investigate the inhibitory effects of traditional Chinese medicine (TCM) on hypermelanosis and provide experimental evidence for treating skin pigmentary disorders. Methods Five TCMs with strong inhibitory effects on tyrosinase activity were tested. The changes of the number and morphology of melanocytes induced by UVB were observed in the experimental hypermelanosis model (brownish guinea pig). Results Decreased melanocytes and melanin granules were found with the treatment of Poria cocos, Polyporus umbellatus, Cornus officinalis Sieb. et Zucc., Atractylodes macrocephala Koidz., Astoagalus complanatus R. Br. ex Bge. Conclusion There are inhibitory effects on hypermelanosis induced by UVB with the treatment of Poria cocs, Polyporus umbellatus, Cornus officinalis Sieb.et Zucc., Atractylodes macrocephala Koidz., Astoagalus complanatus R.

Objective To explore the correlation between ATF5 protein expression level and drug sensitivity of gastric cancer AGS cells.Methods We established the high,middle and low ATF5 expression groups by transfecting the AGS cells with ATF5 pcDNA3.1 plasmid,ATF5 siRNA and empty plasmid using the liposome transfection technique.Then we detected the expression of the ATF5 protein of the 3 groups using the Western Blot.The drug sensitivity of AGS cells in 3 groups to paclitaxel and cisplatin was detected using the MTT experiments and plate clone formation experiments then the correlation between ATF5 protein expression level and drug sensitivity of gastric cancer AGS cells was analyzed.Results With the effect of paclitaxel or cisplatin on AGS cells in 3 groups,the surviving fraction and the IC50 of high ATF5 expression group were higher than those of control group,which indicated statistical significance (all P ＜ 0.05);while the surviving fraction and the IC50 of low ATF5 expression group were lower than those of control group (all P ＜ 0.05,P cisplatin =0.00,P paclitaxel =0.002).We found that cell clone formation of AGS cells to paclitaxel and cisplatin was significantly increased after the transfection with ATF5 protein plasmid and decreased after transfection with ATF5 siRNA plasmid (all P ＜ 0.05).Conclusion The expression of ATF5 protein is related to the drug sensitivity of gastric cancer AGS cells that upregulation of ATF5 protein expression can decrease the drug sensitivity of AGS cells to paclitaxel and cisplatin in gastric cancer.

Jaundice occurs in 19%-40% of the hepatocellular carcinoma (HCC) patients. HCC associated jaundice may be divided into hepatocellular and icteric types in terms of its underlying pathophysiology. The jaundice of icteric type is caused by obstruction of the bile duct through cancer embolus, blood clot, biliary sludge, tumor compression or infiltration. Jaundice and epigastric discomforts are the main clinical manifestations. In the present case, severe acute pancreatitis and acute cholangitis presenting as initial complaints of icteric type HCC were quite rare. A tumor located at the central lobe of the liver and a cancer embolus at the lower part of the common bile duct (CBD) were detected by CT scan. Curative resection of HCC with CBD exploration eradicated both the tumor and the embolus, and no recurrence was found after a 36 month follow-up.

Objective To investigate the status quo of new allocated nurses to master relevant knowledge of blood specimen collection.Methods 197 new allocated nurses and young nurses within 5 working-years were included and the new allocated nurses accepted knowledge training of blood specimen collection.Differences in training effect between nurses with different work experience and education background were analyzed.Results Average score of new allocated nurses before training was lower than young nurses,while after training,there was no difference between them.The training score of new allocated nurses did not correlate with their background before and after training.Conclusions In order to improve the quality of testing and prompt development of new nurses,the department of clinical nursing should strengthen the relevant training about knowledge of blood specimen collection in new allocated nurses.

Objective To investigate the effects of postoperative adjuvant chemotherapy (CT) and chemoradiotherapy (CRT) or radiotherapy(RT) for Ⅰ b-Ⅱ a cervical cancer with risk factors.Methods From March 1995 to June 2010,there were 137 patients underwent radical hysterectomy and systematic pelvic lymphadenectomy for stage Ⅰ b-Ⅱ a cervical cancer admitted at Peking University First Hospital.These patients had risk factors,intermediate risk factors including bulky tumor (＞4 cm),lymph vascular space invasion,deep stromal invasion; high risk factors including positive surgical margin,parametrial invasion,lymph node involvement.Of the all patients,79 cases of them were treated with CT,58 of them were treated with RT or CRT.The 5-year survival and prognosis factors were analyzed retrospectively,the prognosis was compared between two adjuvant therapy groups.Results The univariate analysis shown that types of pathology,different grade of risk factors,stroma invasion and lymph node involvement were prognostic factors of 5-year overall survival Patients with squamous cell carcinoma,intermediate risk factors,no parametrial invasion,and no lymph node involvement had better prognosis (P ＜ 0.05).Whether patients with high-risk factors or intermediate-risk factors,the 5-year overall survival and 3-year disease-free survival had no difference between CT and RCT or RT groups respectively.Cox regression multivariate analysis of survival indicated that clinical stages,types of histology,different grade of risk factors were independent prognostic indicator.Patients with early stage,squamous cell carcinoma,intermediate risk factors had better prognosis.Univariate and multivariate analysis indicated that different postoperative adjuvant therapies had no effects on the prognosis.The 5-year overall survival was 88.6％ in patients treated with CT,and 89.7％ in patients treated with RT or CRT (P =0.455).Conclusion There are equivalent therapeutic results between CT and RT or CRT for patients with risk factors after radical surgery,CT may be as one choice of postoperative adjuvant therapy for stage Ⅰ b-Ⅱ a cervical carcinoma with risk factors.

Two kinds of different functional groups modified RuBpy-doped silica fluorescent nanoprobes Probe A and B that conjugated with avidin were prepared for the recognition of liver cancer cells. Firstly RuBpy-doped silica nanoparticles were synthesized by reverse microemulsion and modified with different functional groups, then Probe A was prepared by the conjugation of avidin with carboxyl modified nanoparticles through covalent binding using 1-ethyl-3-( 3-dimethylamino propyl ) carbodiimide hydrochloride ( EDC )/sulfo-NHS, whereas Probe B was prepared by the conjugation of avidin with the polyethylene glycol ( PEG) linkers on the surface nanoparticles using cyanogen bromide method. Therefore, compared with Probe A, Probe B was obtained by coupling avidin to the nanoparticles through long-chain PEG molecules. The two probes were incubated with liver cancer cells respectively, and microscopic fluorescence imaging shows that Probe B which contained PEG molecules could be more effectively applied for the recognition of tumor marker carcinoembryonic antigen ( CEA) in liver cancer cells.

OBJECTIVETo compare the clinical effective differences between pricking blood combined with moxibustion and west medication for acute gouty arthritis.

METHODSForty patients with acute gouty arthritis were randomly divided into a pricking blood combined with moxibustion group (a combination group) and a western medication group, 20 cases in each one. In the combination group, pricking blood was used at the most painful points of the red turgid and painful joint once three days, total 3 times; moxibustion was applied at the same joint for 15-20 min, once a day. The moxibustion was adopted for 10 days. In the western medication group, 0. 3 g ibuprofen was prescribed orally twice a day for 10 days. The changes of uric acid (UA), high sensitivity C-reactive protein (hs-CRP), erythrocyte sedimentation rate (ESR) and the joint syndrome and symptom score before and after: treatment were observed. Results In the two groups, the UA, the hs-CRP, the ESR and the joint syndrome and symptom scores were lower than those before treatment (all P<0. 05). After treatment, the UA, the ESR and the joint syndrome and symptom scores in the combination group were declined more apparently than those in the western medication group (all P<0. 05). The total effective rate in the combination group was 85. 0% (17/20) which was better than 75. 0% (15/20) in the western medication group (P<0. 05).

CONCLUSIONPricking blood combined with moxibustion could improve the joint symptoms more effectively and the effect is better than ibuprofen orally.
