Sensitivity toward pictorial sexual information was tested implicitly in 448 servicemen from four different arm services and 86 civilians. 20 pairs of pictures containing sex information for sensitivity test were screened out in prior-experiment, and then they were exposed to the test subjects with a 500 ms duration, in order to find out the difference in the subjects' preference in selecting sexual and non-sexual information pictures. The result showed that, compared with the civilians, all the four groups of servicemen showed stronger inclination in selection of sexual information pictures, however there was no group difference or gender difference. The results also suggested that, implicit experiment with paired pictures could be one kind of reliable and effective method in studying sex information sensitivity.

In order to study the mental health status of military personnel under settings of special military operations, 1 263 officers and crew of a submarine base, 361 officers and crew of a naval base and 753 officers and soldiers of a missile base were subjected to SCL-90 scale evaluation. The results were compared with mililary norms and civilian norms. It was revealed that SCL-90 of all the members of three groups had higher scores on every factor compared with the eivilion norms. Besides somatic factors, the scores of other factors were also higher than that of military norms. The results suggested that certain special military operation settings could exert negative impact on the mental health status of military personnel. An analysis of the results also showed that the greatest impact was found in submarine and naval officers and crew, as well as in missile troops, indicating that highly enclosed settings could strongly influence the mental health of individuals.

Objective To investigate the correlationship of second-trimester serum human chorionic gonadotropin (hCG) level and preeclampsia, premature rupture of membranes and preterm delivery. Methods 200 cases of second-trimester gestational serum hCG level was determined by radioimmunoassay,and the pregnancy outcome was followed up. Results The maternal serum hCG level in every gestative week has no significant differences;hCG level of pregnancies with preeclampsia,premature rupture membranes and preterm delivery was significantly higher than normal pregnancies. The rate of developing preeclampsia,premature rupture of membranes and preterm delivery in those hCG ≥2MOM patients (30.9%、35.8% and 14.8% respectively)was significantly higher than those MshCG

Objective To investigate the clincal characteristics of central hyponatremia.Methods The clinical data of 34 patients with central hyponatremia were analysed retrospectively.Results 34 patients with different cerebral diseases appeared dysphoria,sleepiness,aggravating disturbances of consciousness,vomiting,limb seizures and dehydration basis on primary diseases during the hospitalization.The laboratory examinations showed that the level of blood natrium was 260 mmol/d in all the cases,and the central venous pressures in 5 cases were lower than 6 cm H2O among 8 cases.The 19 cases were diagnosed as central hyponatremia——syndrome of inappropriate ADH secretion(SIADH);7 cases were diagnosed as central hyponatremia——cerebral salt wasting syndrome(CSWS).The other 8 cases were diagnosed as SIADH firstly,but final diagnosis were corrected as CSWS according to the symptoms increasing after dehydration therapy.The 19 case of SIADH received the therapy of limiting water and diuresis,and 15 cases of CSWS received the therapy of hydration and supplementing sodium.The several days after the treatment,the levels of the blood natrium and the urinary natrium were backed to the normal values in all the patients and the condition was improved exapet 3 cases remained coma.Conclusions Hyponatremia,hypernatruria and changes of consciousness are the clinical charateritics of central hyponatremia.The treatment principle in SIADH is limiting water,and in CSWS is hydration and supplementing sodium.

Objective To enhance the knowledge of pulmonary aspergilloma on CT and chest radiography. Methods CT scans and chest radiographs of 10 cases with pulmonary aspergilloma were reviewed retrospectively. Of these 10 patients,9 were men,1 was woman, ranged in age from 25～55 years old(means 36.4 years old).Results Of 10 cases,8 cases manifested themselves as an oval or round masses .9 cases were located both upper lobes. Air crescent sign or air ring sign were shown in all 10 cases. The fungus ball could move with the change of patient’s body position in 3 cases.Conclusion A mobile intracavitary mass with air crescent sign or air ring sign is the imaging characteristic of pulmonary aspergilloma.

Ethyl carbamate (EC) as a potential carcinogen commonly exists in traditional fermented foods. It is important eliminate urea that is the precursors of EC in many fermented foods, including Chinese Rice wine. On the basis of achieving high-level overexpression of food-grade ethanol-resistant acid urease, we studied the hydrolysis of urea and EC with the recombinant acid urease. Recombinant acid urease showed degraded urea in both the simulated system with ethanol and Chinese Rice wine (60 mg/L of urea was completely degraded within 25 h), indicating that the recombinant enzyme is suitable for the elimination of urea in Chinese Rice wine. Although recombinant acid urease also has degradation catalytic activity on EC, no obvious degradation of EC was observed. Further investigation results showed that the Km value for urea and EC of the recombinant acid urease was 0.7147 mmol/L and 41.32 mmol/L, respectively. The results provided theoretical foundation for realizing simultaneous degradation of urea and EC.

ObjectiveTo study the value of quantitive scoring methodby ultrasound in differential diagnosis of thyroid nodule.MethodsTotally 1 360 patients with thyroid carcinoma or nodular goiter were given preoperative ultrasound examination of thyroid. The features of thyroid nodule and their signiifcances in diagnosing thyroid carcinoma were evaluated by logistic regression analysis. Surgical pathology was taken as golden standard. Signiifcant feature was scored as 1 point, and insigniifcant feature was scored as 0 point. In two groups, the data were analyzed statistically.ResultsLow echo, obscure boundary, incomplete or no capsule, incomplete or no halo, aspect ratio≥1, internal lfow, posterior acoustic attenuation, no cystic echo, microcalciifcation and background Hashimoto′s thyroiditis showed correlation with malignancy. There were statistically significant difference between thyroid cancer and nodular goiter in thyroid nodules scores (χ2=802.08,P<0.05). Of 768 thyroid nodules with<6 points, 742 were benign and 24 were malignant. Of 60 thyroid nodules≥10 points, 2 were benign and 58 were malignant. Of 314 thyroid nodules with 8-9 points, 60 were benign and 254 were malignant. Of 368 thyroid nodules with 6-7 points, 155 benign and 213 were malignant.ConclusionsQuantitive scoring of thyroid nodule had clinic signiifcance in differential diagnosis. Thyroid nodule with>8 points accounted for the majority of malignancy and should be considered for surgery.

Aim To study cytokine(CK) changes of IL-6,IL-8,sIL-2R and TNF-a levels in sera from patients with juvenile rheumatoid arthritis(JRA) and rheumatoid arthritis(RA) and its correlation with the conventional inflammation indexes,erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP). Methods Levels of IL-6,IL-8,sIL-2R and TNF-a in serum from 30 JRA patients and 34 RA patients,in the synovial fluid (SF)from 4 JRA patients,7 RA patients,6 osteoarthritis(OA) patients and 9 meniscitis(MT) patients were detected by sandwich ELISA. Results As compared with control group,① levels of IL-6 and SIL-2R in sera from 30 JRA patients and 34 RA patients and levels of IL-8 in sera from 30 JRA patients possessed marked difference P∨ 0.01 and P∨ 0.05,respectively.② There were significant difference among serum IL-8 and sIL-2R levels from systemic JRA patients, pauciaticular JRA patients,and serum IL-6 levels from polyarticular JRA patients(P<0.01). ③ There were remarkable difference among SF sIL-2R levels from 4 JRA patients and 7 RA patients and in SF IL-6 levels from 7 with RA patients.④ There were obvious correlativity between serum IL-6,sIL-2R levels and changes of serum ESR and CRP from the JRA patients(r=0.532 and r=0.621,respectively). Conclusion ① IL-6 and sIL-2R exhibit a close correlativity with the activity of JRA and RA,which is the main index of activity of JRA and RA diseases.② sIL-2R might not only participate in systemic pathologic process in JRA and RA diseases,but also serves as a major CK in local articular injuries.IL-6 participates in local articular injuries too,and seems to play a more important role in local articular injuries of RA.③ IL-8 may participate in systemic pathologic process of JRA,but play a minor part in local articular injuries.

Objective To compare the analgesia effect of transversus abdominis plane(TAP) block and caudal block after radical surgery of Hirschsprung’s disease.Methods Sixty pediatric pa-tients,52 males,8 females,aged 1-3 yr,of ASA physical status Ⅰ or Ⅱ,scheduled for elective rad-ical surgery on Hirschsprung’s disease,were equally randomized into TAP block group(group TAP) and caudal block group (group CA).0.2% ropivacaine 1 ml/kg was used in both blocks.FLAAC scores were measured at 6,12,18 and 24 h after surgery.The requirement of sufentanil every 6 h, the first passage of flatus,the time of removing urine tube and the incidence of nausea and vomiting within 24 hours were recorded.Results Compared with group TAP,FLAAC scores and the require-ment of sufentanil were significantly decreased at 6 h after operation in group CA(P <0.05).FLAAC scores and the requirement of sufentanil were similar at 12,18 and 24 h in the two groups.The first passage of flatus,the time of removing urine tube in group TAP were significantly shorter than group CA(P < 0.05 ).The incidence of nausea and vomiting were not significantly different in the two groups.Conclusion Although both TAP block and caudal block can provide effective analgesia for the pediatric patients after radical surgery on Hirschsprung’s disease,caudal block provided superior anal-gesia at early stage after operation,however,TAP block is more beneficial for earlier recovery of bowl function.

Objective To observe the clinical efficacy of Yaoyi-Shenhuojiu combined with synthetic rehabilitation therapy on shoulder-hand syndrome after stroke (SHSAS).
