Based on the state of the development of the body and the subcutaneous fat of 4314 students (includidg boys and girls) at four middle schools in Zibo City, the fat was appraised and analyzed by the body-block indexand the thickness of the subcutaneous fat. The stand-ard-proposal value was also put forward by using y+1.645 Sy.x as the dividing-line value of the groups of different ages and the fat of both sexes. The comparison with foreign standards concerned showed that tally rate of the musculus triceps brachii and the shoulder-blade region of the fat sufferers was 76.87% and 51.7%. The tally rate of the sum of the above two terms reached 100% among the male and the female groups, from 15 to 18 years old. According to the current appraisable standard, the rate of fat children and juvenile for male was 2.86%, while for female, 4.0%. It was obvious that the rate of occurrence for female is higher than that for male(P

Objective To investigate the influence of different concentrations of allicin in apoptosis of A549 cells induced by porphyromonas gingivalis (P.gingivalis). Methods The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of allicin in inhibiting P.gingivalis were investigated by broth dilution methods. The tetrazolium salts (MTT) assay was used to detect the viability of A549 cells infected by P.gingivalis and treated with different concentrations of allicin (64 mg/L, 96 mg/L and 128 mg/L). The flow cytometry FITC/PI staining was used to detect apoptotic rates of A549 cells treated by P.gingivalis and/or allicin for 24 h. Results The values of MIC and MBC of allicin for inhibiting P.gingivalis were 64 mg/L and 128 mg/L respectively. MTT assay showed that the cell viability was significantly increased with the increased concentration of allicin in a concentration-dependent manner (P < 0.05). There was no significant difference in cell viability between allicin (128 mg/L) group and control group, which showed that allicin was no significant cytotoxicity in A549 cells. Flow cytometry assay showed that the apoptotic rates from high to low were P. gingivalis group>P. gingivalis+allicin group>allicin group>control group with significant differences (P<0.01). The apoptosis of A549 cells induced by P.gingivalis was significantly inhibited by allicin (P<0.01). Conclusion Allicin can inhibit P.gingivalis infection in lung epithelial cells. There is a good prospect in the application of allicin in the treatment of pulmonary infection in patients with periodontitis.

PurposeTo explore the application of ultrasonography-guided core needle biopsy (US-CNB) in diagnosis of breast phyllodes tumor, in order to provide a reliable basis for operation selection, and to improve prognosis.Materials and MethodsFifty-seven patients with diagnosed or suspected phyllodes tumor of the breast (PTB) were retrospectively studied. Ultrasound results and US-CNB biopsy data were compared with surgical pathology results.ResultsFor all the 57 cases of PTB, US-CNB revealed 46 benign cases, 8 cases of suspected borderline PTB, and 3 cases of mesenchymal malignant tumors. The postoperative pathological diagnosis of all the patients included 48 cases of benign tumors, 6 cases of borderline tumors, and 3 cases of malignant tumors. Compared with the postoperative pathology, US-CNB had sensitivity of 95.83%, speciifcity of 100.00%, the coincidence rate of 96.49%, the misdiagnosis rate of 4.17%, and misdiagnosis rate of 0%. The Youden's index was 0.96, andKappa was 0.8345. ConclusionUS-CNB has high sensitivity, speciifcity and coincidence rate in diagnosis of PTB.

Purpose To study the value of the ultrasonic imaging in the diagnosis and differential diagnosis of benign and malignant breast tumor. Methods Color doppler ultrasound examination were conducted in 262 cases of patients with breast tumor. The mor-phology of the tumor, edge, envelope, internal echo, microcalcification, length and breadth ratio, axillary lymph node and blood-flow signals of color doppler in breast tumors were observed and these results were compared with the pathological observation postoperation. Results There were 314 tumors in all cases, the coincidence rate in the diagnosis of benign breast diseases with ultrasonic imaging and pathological diagnosis was 97. 3%, the misdiagnosis rate was 2. 7%. The coincidence rate in the diagnosis of breast malignant tumors with ultrasound imaging and pathological diagnosis was 92. 9%, the misdiagnosis rate was 7. 1%. There were statistically signif-icant differences between benign tumors and malignant tumors in the tumor shape, edge, echo, microcalcification, length and breadth ratio, axillary lymph node imaging characteristics (P<0. 01). Conclusion Ultrasound imaging can be more accurate diagnosis and i-dentification of benign and malignant breast tumors.

Objective To study the effect and the possible mechanism of delavirdine on muhidrng resist-ance-aasociated protein 2(MRAP2)-mediated multidrug resistance in LLC/cMOAT cells. Methods MTT assay was used to determine the effects of delavirdine on proliferation of LLC/CMV and LLC/cMOAT cells. The inhibitory effects of vincristine (VCR),cisplatin (DDP),adriamycin (ADM) and etoposide (VP-16) used alone or in combi-nation with delavirdine on the proliferation of LLC/CMV and LLC/cMOAT cells were evaluated by MTT assay. The cell cycle distribution, the apoptosis rate of the cells treated with different concentration of delavirdine and the intra-cellular concentration of ADM were determined by flow cytometry (FCM). Results Delavirdine at the concentration of 4 μmol/L and below showed no significant cytotoxicity to LLC/CMV and LLC/cMOAT cells. The resistance of LLC/cMOAT cells to VCB, VP-16, ADM and DDP were 9.58,1.11,2.98 and 3.96 folds of that of LLC/CMV cells. When 2 μmol/L delavirdine was added, the resistance was 5.21 and 2.55 folds respectively;when 4 μmol/L dela-virdine was edded,the resistance was 7.56 and 3.03 ,while 2,4 μmol/L delavirdine made no significant changes to the chemosensitivity of LLC/CMV cells to VCR and DDP(P>0.05). Cellular cycle analysis demonstrated that 0,6, 12,24 hours after co-cultured with delavirdine the amount of cells at G1 phase increased from(38.92±0.15)% to (56.87±2.23)%,(65.36±2.76)% and (74.77±5.06)%. The cell apoptosis rate increased from 1.77% to 17.45% and 28.52% when treated with delavirdine at 2,4 μmol/L and VCR for 24 h. When treated with 2,4 μmol/L delavirdine, ADM accumulation in LLC/cMOAT cells was enhanced significantly(P<0.05). Conclusion DLV can partially reverse the multidrng resistance of LLC/cMOAT cells, and the reverse effect correlates to the concentration. The possible mechanism may involve the growth arrest at G1, increasing of intracellular drug concen-tration and promoting apoptosis.
