Objective To explore the effect of ultrasound assisted liposuction in vivo on clinical aesthetic plastic surgery. Methods Ultrasonic lipoplastics combined with swelling liposuction were used in 153 cases of the beauty seekers. Application of rountine tissue swelling technique with the transduction of ultrasound into fatty areas made atipose cells broken and emulsified, and it also easy to move the atipose tissue rich in connective fibres. Results All the patients were satified with the aesthetic effects after the operation. Smoothness and softness of the operated areas with obvious shrinkage of the skin were found with few complications. Conclusion Ultrasound assisted liposuction is an effective and simplified method and deserves to be widely used.

Objective To study the clinical effects of abdominoplasty using ultrasound assisted liposuction and dermolipectomy. Methods With the patient standing, the relative areas of maximal adipose fullness in the abdomen and waist were marked topographically. With the patient in the supine position, the "pinch test" was performed by surgical operator advancing the tissue in the infraumbilical area toward the pubic region in order to estimate how much skin needed to be resected before operation. Inter-operatively tumescent technique with the transduction of ultrasound into fatty areas was applied in the first place, following classic abdominoplasty including excessive skin and fat resection, musculoaponeurotic plication and umbilical transposition. Results Sixteen patients followed up from six months to two years were satisfied with aesthetic effects because of smoothness of the operated areas, good sensory recovery and obvious shrinkage of skin with fewer complications. There were no infection, skin necrosis, and wound dehiscence. Conclusion The excellent effects of abdominal profile sculpture can be reproduced with the new method using UAL in vivo and dermolipectomy.

Objective To investigate a myocutaneous flap method for eyelid baggy plasty conforming to the medical aesthetic requirements. Methods Before operation the amount of the lower eyelid skin excised should be determined. Asking the patient to look upward at supine position, the operator lifted properly the lower eyelid skin using fine forceps without teeth at the results of smooth superficialness at this region and slight ectropion. The incision lines were marked along the print pinched by forceps and the trace 2 to 3 mm below the ciliary margin. Intra-operatively severing soft issues to the inferior orbital fringe just on the sub-orbicularis level, the skin-muscle flap was made. Then the excessive muscle was removed in the light of the incision lines. The orbital fat teased out resected or filled up the concavity along the lower orbital edge. Results The tense and smooth appearance of lower eyelid was archived in 900 cases received in our hospital except 2 temporary ectropion cases and 2 temporary double vision cases. We repaired the 15 ectropions using adjacent skin flap, tarsal reduction, skin soft tissue expansion, or superficial temporary fascia sling suspension, eliminated 28 haematomaes and made the excision of scar and wound suture for a hypertrophic scar case in the 150 complications from other hospitals. The crow wrinkles were improved apparently. Conclusion The amount of skin excision determined pre-operatively, which not only successfully refrains interfering elements from blooding and swelling but also avoids giving rise to ectropion, is accurate than that performed during operation. Natural appearance after operation becomes better and lasting because of orbicularis raised which strengthens the anterior wall of orbital septum.

The study on tumor metabolism has been gradually be-come a hot spot in recent years .A lot of proteins involved in the regulation of tumor metabolism especially the glucose transporter protein 1(GLUT1).As a key regulatory factor mediating energy metabolism within tumor cells , GLUT1 can regulate the glucose intake and maintain the basic level of metabolism in tumor cells . More importantly, the abnormal expression of GLUT1 was asso-ciated with many kinds of tumors , of which GLUT1 was used to meet the energy requirement for the fast growth of tumor .Thus GLUT1 also played a crucial role in growth , differentiation and metastasis of tumor cells and prognosis of tumors .Meanwhile , as three-dimensional crystal structure of GLUT 1 was determined , it is possible to design the small molecular inhibitors of GLUT 1, which can realize “starve to death” tumor cells.GLUT1 can be a particularly attractive target for tumor treatment and interfer-ence.The relationship between abnormal expression of GLUT 1 protein and tumor metabolism was reviewed . Moreover , the mechanism of tumor metabolism regulated by GLUT 1 protein ex-pression and treatment of cancers were discussed , which may provide references for future research and clinical treatment .

Objective The method transcranial Doppler (TCD)and end-tidal carbon dioxide partial pressure (ETCO2 ) was used to investigate the cerebrovascular reserve capacity in patients with intracranial artery stenosis.Including the cerebral vasodilator reserve,contracted reserve and the overall reserve.Methods The 72 cases were enrolled in this study,include of 42 patients with one or two sides middle cerebral artery (MCA) stenosis,or other intracranial artery stenosis and 30 normal persons. All the patients were routinely examined with TCD,and the TCD QL software was used to evaluate the cerebrovascular reserve. Hypercapnia was induced by inhaling the CO2 who breathed himself,and hypocapnia was induced by voluntary hyperventilation. The changes of velocities were recorded in both side of MCA,and the ETCO2 was recorded by the external measuring device. Results ( 1 ) The cerebral vasodilator reserve of one side of MCA stenosis group ( ( 3.65% ± 2. 62% )/mm Hg),the heavier side of multi-vessel stenosis group ( ( 1.99% ± 2. 78% )/mm Hg ),and normal control group ( left ( 3.54% ± 1.66% )/ mm Hg; right (3. 81% ± 1.63% )/mm Hg) had significant difference( F = 3. 755 ,P ＜ 0. 05 ). The heavier side of multivessel stenosis group' s cerebral vasodilator reserve were significantly lower than normal control group ( t =- 2. 546,P ＜ 0. 05 ). (2) The overall reserve of one side of MCA stenosis group ( ( 3.22% ± 1. 27% )/mm Hg),the heavier side of multi-vessel stenosis group( (2. 30% ± 1.14% )/mm Hg),and normal control group(left (3. 19% ±0. 81% )/mm Hg;right (3. 23% ±0. 70% )/mm Hg)had significant difference(F=5. 894,P ＜0. 01 ). The heavier side of multi-vessel stenosis group' s overall reserve were significantly lower than normal control group( t = - 3. 357,P ＜ 0. 01 ) and they were also significantly lower than one side of MCA stenosis group (t = 2.471,P ＜ 0. 05 ). (3) The extent of vascular disease correlated inveresely to the cerebral vasodilator reserve( r = - 0. 322,P ＜ 0. 05 ) and the overall reserve( r = - 0. 364,P ＜ 0. 05 ) in the heavier side of patients who have vascular disease.Conclusions ( 1 ) TCD with ETCO2 is a simple,economic and effective method for assessing CVR. (2)The capacity of cerebrovascular reserve was reduced in patients with intracranial artery stenosis.

Tumor metastasis is one of the important biological characteristics of malignant tumor,which is closely related with the prognosis of the cancer patients.High expression of ADAM8 in varieties of tumors was revealed in many recent studies,and such aberrant expression played a crucial role in regulating of tumor metastasis.Studies showed that overexpression of ADAM8 attenuated the intercellular adhesion effect,promoted tumor angiogenesis,and enhanced the degradation of ECM as well as the releasing of cytokines.Therefore,suppression of ADAM8 may lead to inhibition of tumor metastasis,which makes ADAM8 a particular attractive target as it can be used as a prognostic indicator and a potential therapeutic target of malignant tumor.A review about the relations between ADAM8 protein′s abnormal expression and tumor occurrence was discussed in this paper,also include discussion about the mechanisms of ADAM8 protein′s disorder-induced tumor formation,as well as therapeutic strategies based on ADAM8-targeted,which may provide references for follow-up research and clinical treatment.

BACKGROUND AND OBJECTIVEThe expression levels of glucose-regulated protein 78 (GRP78) were elevated and correlated with resistance to chemotherapy drug VP-16 in lung cancer cells. However, little is known about the relationship between its expression and resistance to cisplatin in lung cancer cells. The aim of this study was to investigate the expression of GRP78 under the induction of A23187 and its significance in the resistance to anti-tumor drugs cisplatin in a human lung cancer SPCA-1 cell line.

METHODSRT-PCR and Western blot were used to analyze the expression of GRP78 at mRNA and protein levels in SPCA-1 cell line induced byA23187 at different concentrations (0, 1, 2, 4, 6 microM). MTT was used to determine the effect of cisplation on cell survival.

RESULTSThe expressions of GRP78 at both mRNA and protein levels were increased obviously in SPCA-1 cell line induced by A23187, with a manner of dose-dependent of A23187 to a great degree; MTT assay showed that the cell survival rate of the A23187-induced group decreased significantly compare to the control group, also with a concentration-dependent manner of A23187.

CONCLUSIONThe expression of GRP78 at both mRNA and protein levels were increased obviously in SPCA-1 cell line induced by A23187. The enhancement of GRP78 showed a negative correlation with the cell survival rate treated by cisplatin. All these indicated that overexpression of GRP78 can enhance the sensitivity to cisplatin and there is correlation between the expression of GRP78 and resistance to cisplatin of human lung cancer SPCA-1 cell line.

Objective? To investigate the status of professional identity,job burnout and organizational affective commitment of dental clinic nurses and analyze their correlation. Methods? Cross-sectional study was carry out on 275 dental clinic nurses from 14 Class Ⅲ hospitals in Beijing, as measured by Professional Identity Scale, the Revised Edition of the Maslach Burnout Inventory-General Survey and the Affective Commitment Scale(ACS). The statistical analysis performed by SPSS 24.0 and Amos 21.0 software. Results? The score of Professional Identity Scale of 237 dental clinic nurses was(121.34±20.34), moreover the nurse who working in general hospitals exhibited higher score than in dental-specialized hospitals,the difference was statistically significan(t P=0.041). The score of the Revised Edition of the Maslach Burnout Inventory-General Survey of 237 dental clinic nurses was (1.96±1.02),the average score of entries of ACS was (4.07±0.79). The results of the analysis showed that the professional identity scores of nurses with different working years were statistically different (P＜0.05). The scores of nurses with different working years, academic qualifications and professional titles were statistically different on Job burnout (P＜0.05). Moderate correlations were found among the scores of professional identity, job burnout and organizational affective commitment (P＜0.001), while organizational affective commitment had an intermediate effect between professional identity and job burnout, accounting for 31.5% of total effects. Conclusions? The status of professional identity and organizational affective commitment of dental clinic nurses in tertiary hospitals is at moderate-to-high level, and the status of job burnout in most of them is at low-to-moderate level. Moderate correlations are found among them, while organizational affective commitment plays an intermediate role between professional identity and job burnout. In order to reduce job burnout and establish harmonious and stable working environment, nurse administrators should implement intervention to improve professional identity and enhance organizational affective commitment.
