Objective To review the clinical data of reduction mammoplasty by central pedicle technique,and to summarize all kinds of the complications to modify the technique for improvement of long term aesthetic effects.Methods The postoperative complications were analyzd and then an approach was used to investigate the pattern of the blood supply and the nerve distribution of breast.Based on the anatomical study,a modified double-circle reduction mammoplasty technique was designed to treat patients with hypertrophical breasts. Results With a follow-up for 3 months to 3 years,the patients who underwent this modified central pedicle technique,had an invisible scar,good projection,the better shape of breast and preserved their sensation of nipple-areola complex.Conclusions Modified central pedicle technique is a safe and reliable technique,especially ideal for Chinese women.The blood supply is rich and the sensation of nipple-areola complex is preserved.The fixation of the gland tissue is more important than the dermal-bra.

Objective To investigate the expression and significance of the human telomeruse gene (hTERC)in the cytologic specimens of cervix for early cervical lesion screening.Methods Cytologic samples of cervix including 120 normal persons,86 CIN patients and 14 SCC patients were analyzed for aberrations of 3q26 using a commercially available two-color FISH probe.Results Positive expression rates of hTERC gene in normal,CIN Ⅰ ,CIN Ⅱ,CIN Ⅲ and SCC samples were 1.7%(2/120),2.6%(1/38),55.6%(10/118),87.5%(14/16),100.0%(14/14),100.0%(14/14),respectively.Compared with CIN Ⅰ/CIN Ⅱ group,hTERC gene positive expressions in SCC/CIN Ⅲ group were higher significantly(P=0.01),and them were also difference between CIN Ⅰ-CIN Ⅲ group and normal controls(X~2=113.52,P ＜0.01).With progression from CIN to carcinoma,polyploidization resulting in aneuploidy and high TERC gene copy numbers in SCC group ascended significantly.Among the total abnormal cells,the number of the cells percentage which hTERC amplification signals was more than 3:3 in CIN Ⅰ ,CIN Ⅱ,CIN Ⅲ and SCC groups were 6.12%,7.98%,28.07% and 33.97%,respectively.Condusion The hTERC gene is increasingly gained with progression of CIN and may appear to be another screening testmarker for early cervical cancer screening and accessory diagnosis.

OBJECTIVETo investigate the application of intense pulsed light (IPL) depilation in the auricular reconstruction with totally expanded skin and its suitable parameter.

METHODSFrom February 2009 to September 2013, one tissue expander(100 or 150 milliliters) were implanted under the skin of mastoid in 126 patients who suffered from microtia. During the skin expanding, the hair on the expanded skin was depilated by JPL technique. The parameter, operation, interval, the depilation result and the complication were recorded. The autologous rib cartilage frameworks were implanted in the second phase of auricular reconstruction.

RESULTSThe energy of IPL was 20 - 35 J/cm2 (mean 25. 3 J/cm2), the width of pulse was 26 - 30 ms ( mean 27. 9 ms), the interval between two operations was 4 weeks. Ninety-six patients were cured(76. 2%, 96/126). The total depilation efficient is 96. 8% (122/126). A fine banding blisters was found in one patient whose depilation areas was marked by black pen. Skin erythema was found in five patients and skin pigmentation was found in 7 patients. There were no skin necrosis and expander exposure in all patients. During 6 - 12 months of follow-up period, ninety-two patients were cured (73.0%, 92/126) and the total depilation efficient is 92. 9% (117/126).

CONCLUSIONSIPL depilation during the skin expanding is feasible and safe with careful procedure. The hairless expanded skin is enough to cover the framework, as well as the post-auricular area. The appearance of reconstructed ear is better without hair.

This study evaluated students’ adaption to the two teaching methods through score analysis and questionnaire of the two classes.Results Students taught by problem-based learning method generally believed that this teaching method can stimulate their learning interest, improve self-study ability, thinking ability, creativity, and language competence, and enhance team spirit.Conclusion Problem-based learning method shows better teaching outcomes than traditional teaching method. It can guide students to look for ways to tackle problems in the course of solving problems, and cultivate all-round ability and comprehensive quality of students.

OBJECTIVETo explore the feasibility of the transdiferentiation of human breast adipose-derived stem cells (hbASCs) into mammary epithelial-like cells after co-culturing in Transwell in vitro.

METHODSThe third passage hbASC and the HBL-100 cell line were co-cultured in a Transwell culture system for 15 days. The hbASCs were observed and identified by inverted phase contrast microscope and transmission electron microscopy, and immunocytochemistry staining in the induced and control groups.

RESULTSBoth the third passage hbASCs and the HBL-100 cell line cells could adhere and grow rapidly after co-culture in the Transwell system. After co-culture for 15 days, the morphology of some induced hbASCs changed into epithelial-like cells. Some induced hbASCs showed positive expression of CK18, CK19 by immunocytochemistry staining, and typical epithelium cells with microvilli, desmosomes and tonofilaments observed under TEM. The positive rate of CK18 and CK19 was (24.4 +/- 12.0)% and (21.6 +/- 16.4)% in experimental group, and (1.8 +/- 1.7)% and (1.1 +/- 0.6)% in control group.

CONCLUSIONThe data suggests that hbASCs may have the potential to transdifferentiate into human mammary epithelial-like cells after co-culturing in Transwell in vitro.

ObjectiveTo study the clinical features of the bilateral frontal brain contusion with cerebral hernia center and its treatment strategies. MethodsThe clinical data of 76 patients with cerebral central hernia were restropectively analyzed. ResultsIn 76 patients,there were 53 cases survive,23 cases died.The life and survival quality of these patients were evaluated according to the Karnofsky scale systerm :46 patients underwent surgery,including 35 cases with good recovery,8 cases with long-term coma or unable to look after themselves,3 cases with death;10 cases underwent a expectant treatment,of which,6 cases with good recovery,4 cases with long-term coma or unable to look after themselves.The other 20 cases died of central brain stem failure,with a central hernia when admissioned. ConclusionPatients with bilateral frontal brain contusion were extremely complicated with central hernia,and had a suddenly deteriored condition.Close observation of changes were critical importance.The surgery should be carried out before "diencephalon period",for most recovery well after surgery.Patients with diffuse brain swelling should go under the depressioning surgery as earlier as possible.

This study investigated the changes of CD4(+) CD25(+) regulatory T cells (Tregs) in peripheral blood of patients with hepatocellular carcinoma before and after transcatheter arterial chemoembolization (TACE). The proportion of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in peripheral blood of 33 patients with hepatocellular carcinoma was determined by flow cytometry before, 1 week and 1 month after TACE. And 25 healthy volunteers served as control. One month after TACE, the patients were divided into two groups: 22 in group A, who were in stable condition or getting better; and 10 in group B, who were deteriorating. One patient died and was excluded. The results showed that the percentage of CD4(+)CD25(+) Tregs among CD4(+) T lymphocytes did not significantly change in the 33 patients 1 week after TACE as compared with that before TACE, however, the difference was significant (P<0.01) between the patients with hepatocellular carcinoma and the healthy subjects. The percentage of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in group A 1 month after TACE was decreased significantly in comparison with that before and 1 week after TACE (P<0.01), whereas, that in group B was increased significantly 1 month after TACE (P<0.01). It was concluded that patients with hepatocellular carcinoma had a higher proportion of CD4(+)CD25(+) Tregs in peripheral blood. TACE did not significantly affect the level of CD4(+) CD25(+) Tregs within short time (such as 1 week). The proportion of CD4(+)CD25(+) Tregs in peripheral blood 1 month after TACE was related to the prognosis of hepatocellular carcinoma.

Objective There is a lack objective methods for the diagnosis of postoperative cognitive dysfunction (POCD).This study aimed to investigate the influence of propofol or etomidate anes-thesia on the postoperative cognitive function and serum S 100βprotein level in infants . Methods This study included 100 hernia infants aged 1-3 years treated by laparoscopic herniorrhaphy under propofol (n=50) or etomidate anesthesia (n=50).At 1 day before and 3 days after surgery, we assessed the cognitive function of the patients using Bayley Scales of Infant and Toddler Development ( BSID-Ⅲ) and further divided each group into a POCD and a non-POCD sub-group based on the results of diagnosis made according to the Z-scores.Using ELISA, we measured the levels of the serum S100βpro-tein in the iliac venous blood drawn preoperatively ( T0 ) and before PACU ( T1 ) and compared them between the POCD and non-POCD groups. Results At 3 days after operation, POCD was observed in 10 cases (20.0%) in the propofol group and 9 cases (18.0%) in the etomidate group, with no statistically significant differences between the two (P>0.05).The level of the serum S100βprotein was markedly elevated in both the propofol and etomidate groups at T 1 as compared with that at T0(P<0.05), and so was it in the POCD in comparison with that in the non-POCD group (P<0.05), with no statistically significant differences between the two groups at T1(P>0.05).A significant correlation was found between the postoperative S 100βlevel and POCD at 3 days after surgery in both the propofol (r=0.842, P=0.001) and the etomidate group (r=0.821, P=0.001). Conclusion Propofol and etomidate anes-thesia can induce different degrees of postoperative decline of cognitive function in 1-3 years old infants .The post-anesthesia elevation of the serum S100βprotein level is positively correlated with early postoperative POCD and indicates various degrees of brain damage .
