Objective To evaluated a new automate ultra sonographic system for detecting benign and malignant breast tumors in three-dimensions.Methods A magnetic sensor to track the probe in a real time during scanning and a series of sequential cross-sectional images,together with information giving precise location and the direction of movement of the probe,were fed into the computer.Fuzzy logic was used to classify tumor, boundary, and normal breast tissue in order to extract an image of the tumor and its margin through three-dimensional (3D) transformation. Results The difference between the surface roughness of benign and malignant tumors was found by comparing their computer -rendered surface images.The values of the S/V ratio of surface area (S 3) divided by volume (V 2) of malignant tumors were larger than those of benign tumors. Mean ratio was 3.43 in benign tumors, 9.08 in malignant tumors.T-test results showed these differences between benign and malignant tumors to be significant(P

Objective To analysis the clinical characteristics, treatment and prognosis for patients with cervical cancer with lymph lode of paraaortic and /or supraclavicular metastasis after combined treatment in two years. Methods Data of 20 patients with lymph lode of paraaortic and /or supraclavicular metastasis of cervical cancer were analyzed retrospectively. Results There was no evidence of lymph node of paraaortic and supraclavicular metastasis before the first combined treatments according to the MRI/CT/SPECT scans in these 20 patients. However, lymph lode of paraaortic and/or supraclavicular metastasis were seen in two years after treatments, the shortest is two months. One patient was progressing during treatment whose pathologic diagnosis is mucinous adenocarcinoma, died in 6 months from treatment start. There was only paraaortic metastasis in 15 patients, among these, 4 patients were found lymph lode of left supraclavical metastasis after retreatments in 3-6 months. Both paraaortic and left-supraclavical lymph node metastasis in 4 cases. Among these 20 cases, recurrence and to give up treatment, whose median survival time is 7.50 months, recurrence and to gain treatment, whose median survival time is 18.98 months, there was significant difference (x2=7.23, P<0.01). Conclusion Patients with cervical cancer with lymph lode of paraaortic and/or supraclavicular metastasis after combined treatment will obviously extend survival time after retretments, which has positive therapy significance.

Objective To investigate the efficacy and safety of hydrogel soft contact lens(HSCL) for persistence corneal epitheliopathy after intraocular surgery.Design Retrospective case series.Participants 36 patients(36 eyes) with bullous keratopathy(n=5) or other keratopathy(n=31) including corneal erosion,epithelium missing,and dendritic keratopathy after intraocular surgery,which failed to medicine treatment 2 weeks ago.Method All patients were fitted with HSCL after suitable processing of the corneal foci.The lenses were removed immediately as long as the keratopathy recovered.A new lens was replaced after 3 weeks if still needed.Main Outcome Measures Changes of keratopathy,pain relief and complications.Result 35 patients(97.22%) fitted with HSCL were very comfort within 3 days.At the follow-up of 6 months,30 patients(83.33%) achieved complete remission of keratopathy,6 patients (16.67%) remarkable remission.30 patients(86.11%) had vision increase.All of the non-bullous keratopathy recovered within 3 weeks,while the lenses were fitted much longer in bullous keratopathy.No other lens-related complications appeared.Conclusion The application of hydrogel soft contact lens to persistence corneal epitheliopathy after intraocular surgery is safe,effective,and practical.

Objective To observe the relationship between the expression of GFAP and iNOS the post-traumatic intervals after experimental cerebral contusion,in order to attempt to find out a method of timing wound age of brain contusion in the forensic prediction of injury time.Methods After setting up an model of experimental focal cerebral contusion in rats,immunohistochemical method was applied to observing the changes of inducible nitric oxide synthase (iNOS) and glial fibrillary acidic protein (GFAP) staining combined with histology method in rats.The immunostaining results were measured quantitatively with computer imaging analysis system.Results (1) At 3h after injury,GFAP-positive astrocytes around the wounded area were definitely detected.The intensity and the area of GFAP-positive cells increased following the post-traumatic intervals.The intensity peaked dually at 1d and 5d,respectively,followed by reduction at 3d,which revealed two-peak waveforms,The area of GFAP positive cells enhanced significantly at 3h and gradually increased with prolonging survival time,and reached a peak at 7d after injury.(2) At 12h after injury,the iNOS isoform was present and iNOS positive staining cells were noted.The intensity and the area of iNOS positive cells increased following the post-traumatic intervals.The area of positive reached maximal level at 1-3days,gradually subsided after 5d,and maintain a higher lever up to 7d post-injury;but the intensity of individual positive cell gradually increased with prolonging survival time,reached a peak at 5d and gradually subsided after 5d,but the level was still higher than the initial interval.Conclusions Expression of GFAP and iNOS is correlated with post-traumatic intervals after cerebral contusion in rats,suggesting that the expression of iNOS and GFAP may be served as the markers for timing of brain contusion in forensic practice.

Objective To explore the histocompatibility and plasticitity of hydroxyapatite/high-density polyethylene composite (HMPE). Design Experimental study. Participants Forty-five rabbits. Methods Rabbits were randomly devided into HA/PE, HA and PE surgical groups, every group included 15 rabbits. Osteoeetomy of orbital rim and implantation (HA/PE, HA and PE materials were used) were performed on 3 groups of the rabbits. At 1st week, 4th week, 8th week, 12th week and 24th week of postoperation, we took out the samples from the rabbits separately in each group and did histopathologic and electron microscope examinations. Main Outcome Measures Physical signs of the implant combination with the bone. The bone cell appeared in the implants. Results After 12 weeks, the calcium salts deposit like bone plate with some osteoblast inside the HA/PE implants was observed. After 8 weeks, the calci- um salts deposit inside the HA plants was observed. In the PE implants, nothing could be seen but some fibrous connective tissue. Conclusion HMPE is an ideal repair material especially for orbital bone.

Objective To discuss the application effects of CBI teaching method in medical English Teaching of respiration medicine. Methods Dividing 120 students of Grade 2009 in Jining Medical College into two groups including control group (60) and experimental group (60). The tradi-tional teaching method was adopted in the control group and CBI teaching method was adopted in the experimental group. After finishing the courses, medical professional English level test and standard-ized patients test were applied in the two groups. Students' English studying interests and autonomous English learning ability were also investigated by questionnalres. SPSS 17.0 software was used for sta-tistical analysis, and the data were processed by t test and 字2 test, with the level of a test equal to 0.05. Results The medical professional English level test scores, standardized patients test scores and the total average scores of autonomous English learning ability in experimental group were respectively [(81.97±4.91), (80.33±5.85), (3.88±0.38)], and they were significantly higher than those in the control group [(70.40±4.78), (70.48± 4.79), (2.98±0.26), with P values below 0.01]. Satisfaction degrees in the improvement of learning motivation, learning time, learning method, learning attitude and dealing with study difficulties in experimental group were better than those of control group (χ2=13.084, 8.000, 13.297, 11.627, 13.374, P=0.000). Conclusion CBI teaching method is better than traditional teaching method and it transfers English learning into the learning of professional knowledge and skills of respiratory medicine, stirs the interests of students, improves their autonomous English learning ability and strengthens their abilities to learn and apply English language.

OBJECTIVETo explore the effect of Qingfei Huoxue Recipe (QHR) combined azithromycin in treatment of intractable pediatric mycoplasma pneumonia.

METHODSTotally 124 intractable pediatric mycoplasma pneumonia patients at our hospital were recruited in this study, and randomly assigned to the treatment group and the control group, 62 in each group. Patients in the control group took azithromycin, while those in the treatment group additionally took QHR. All patients received omnibearing systematic nursing. Therapeutic efficacy, clinical indices (such as disappearance time of cough and rales, recovery time of body temperature) , and the incidence of adverse reactions were observed.

RESULTSAfter treatment the total effective rate was 91.94% (57/62 cases) in the treatment group and 77. 42% (48/62 cases) in the control group with statistical difference (P < 0.05). Compared with the control group, disappearance time of cough and rales, recovery time of body temperature were obviously shortened in the treatment group with statistical difference (P < 0.01). There was statistical difference in the incidence of adverse reactions between the two groups [3.23% (2/62 cases) vs 38.71% (24/62 cases) , P < 0.01].

CONCLUSIONIn clinical treatment for intractable pediatric mycoplasma pneumonia, Chinese medicine combined Western medicine plus scientific and systematic nursing showed more obvious advantages with significant efficacy, which was worth spreading.
