Breast reconstruction after radical mastectomy significantly improves the patient' s quality of life and has become an important part of comprehensive treatments. However, there are a number of reconstruction problems. The choice of breast reconstruction after breast cancer should be considered in general. Immediate reconstruction is not superior to breast-conserving surgery, while immediate reconstruction is superior to delayed reconstruction, and choices vary between implant reconstruction and autologous reconstruction. In short, breast reconstruction should be based on the radical principle with balance of beauty.

ObjectiveTo observe the clinical efficacy of acupuncture-moxibustion in treating tinnitus.MethodNinety-eight patients with tinnitus were divided into a warm-needling group (n=32), an acupuncture group (n=34), and a medication group (n=32), to observe thetherapeuticefficacies.ResultThe total effective rate was 83.3% in the warm-needling group, versus 78.8% in the acupuncture group and 60.0% in the medication group.ConclusionWarm needling and acupuncture plus TDP are both superior to the medication treatment in comparing the therapeutic efficacy.

Teaching and research section of orthodontics of the Affiliated Hospital of Stomatology of Chongqing Medical University took the lead in carrying out ‘ three early education' Students of stomatology in Chongqing Medical University established ‘ social practice volunteer team' and conducted ‘ three early education' in orthodontic clinic during winter,summer holiday and weekend.This let students of low grades contact with society,clinical practice and scientific research at early stage thus to comprehensively improve their overall quality.Questionnaire for student volunteers of the Affiliated Hospital of Stomatology of Chongqing Medical University showed that ‘ three early education' can effectively improve medical students' comprehensive quality.In the early stages of learning for students of stomatology,we cultivated students' occupation spirit,innovation consciousness,scientific literacy,clinical thinking and teamwork ability by strengthening training of students' social practice ability,communication ability,organization and coordination ability,professional interests,professional senses of belonging,team spirit and moral emotion.We achieved certain results and our experiences are worth extending.

Objective:To study the impact of rotary cell culture system(RCCS) on the quality and activity of fetal islets of pancreas after cryopreservation and resuscitation.Methods:The fetal islets of pancreas were assigned into three groups averagely,experiment group 1,2 and control group.In experiment group1 and 2,fetal islets of pancreas were cultivated in RCCS and common culture respectively.While in control group,fresh fetal islets of pancreas were cultivated in RCCS all the time.We resected the fetal pancreas and digested with Collagenase V and purified with ficoll solution.Then standard cryopreservation step was adopted,and after resuscitation,the islets of pancreas were cultivated continuously.And the quantity,quality and activity of the islets of pancreas,and insulin stimulation test results in all groups were detected.Results:After purification,islets got from one fetal pancreas reached 2,331.98-5,115.43 IEQ(average 3,551.27? 253.76 IEQ) .The survival rate,the insulin release and stimulation index in islets of pancreas of group 1 incubated in RCCS were higher than those in common culture.Conclusion:RCCS are good for the growth and proliferation of islets of pancreas,and the islets of pancreas cultivated in RCCS have better insulin secreting capacity.RCCS combined standard cryopreservation method may further improve the cryopreservation effect.

Objective To investigate the relationship between trace elements and rachitis in children.Methods Three hundred and twelve patients with rachitis and 297 healthy children were selected for this study.Blood zinc(Zn),iron(Fe),plasma copper(Cu),calcium(Ca),magnesium(Mg),lead(Pb) and cadmium(Cd) were assayed by atomic absorption spectrophotometer.Results The levels of Zn,Fe,Cu of rachitis in blood were significantly lower than those of healthy children,while the levels of Mg,Pb were higher.There were significant differences between 2 groups(P

Objective This study seeks to use a meta-analytical approach to quantitatively assess the results of applying the problem-based learning(PBL) teaching model and the traditional lecture-based learning(LBL)teaching model to basic medical courses in undergraduate medical edu-cation. Methods The CNKI and VIP databases were electronically searched to retrieve randomised controlled trial studies that examined the use of PBL methods for basic medical courses in under-graduate medical education. In these studies PBL teaching model was used in experiment group and LBL teaching model was used in control group. Pass rate or test scores was used to evaluate the effect of learning. The retrieved documents ranged from the time that each database was first constructed to December 2012. After two researchers performed literature screening independently, data extraction, and quality assessment procedures in strict accordance with the inclusion and exclusion criteria of this study, the Stata 11.0 software package was utilized to conduct the meta-analysis. Results This meta-analysis examined 28 studies that included a total of 3703 subjects. The modified Jadad scores of 20 studies(71.4%) were less than 4, and those of 8 studies(28.6%) were more than or equal to 4. The meta-analysis revealed that compared with the traditional teaching model, the PBL teaching model did not produce improved examination passing rates for a course [relative risk(RR):1.05, 95%confidence interval(CI):(0.99, 1.10), P=0.098] but could improve examination scores for a course [standardized mean difference (SMD): 0.73, 95% CI: (0.51, 0.96), P<0.001]. Conclusion For basic medical courses in undergraduate medical education, compared to LBL teaching, PBL teaching can improve students' test scores but cannot improve students' pass rate. PBL used in basic medical courses has di-versified forms and lacks unified criterion, so there is still a long way to go for the appli-cation of PBL.

Objective:To evaluate the role of hemopexin (HPX) in cerebral ischemia-reperfusion (I/R) injury in rats.Methods:One hundred and twenty healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 250-280 g, were divided into sham operation group (S group, n=36), cerebral I/R group (I/R group, n=36), vehicle group (V group, n=24), and HPX group ( n=24). The model of cerebral I/R injury was established by 120 min middle cerebral artery occlusion followed by reperfusion in anesthetized rats.At 6, 12 and 24 h of reperfusion, 4 rats in S group and I/R group were sacrificed, and the ischemic penumbra of the ipsilateral cerebral cortex was obtained to detect the expression of HPX by Western blot.In I/R, V and HPX groups, 0.9% normal saline 10 μl, 0.1% NaN 3 10 μl, and 1.86 mg/ml HPX 10 μl were injected into the lateral ventricle, respectively, immediately after reperfusion.Eight rats in each group were selected, and neurological deficit was scored at 1-7 days of reperfusion.Eight rats in each group were sacrificed at 1 and 7 days of reperfusion, brains were removed, and brain tissues were obtained for measurement of infarct size, and the percentage of infarct size was calculated. Results:Compared with S group, the expression of HPX in cerebral ischemic penumbra was significantly up-regulated at 24 h of reperfusion in I/R group, and the neurological deficit scores were significantly decreased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was increased at 1 and 7 days of reperfusion in I/R, V and HPX groups ( P<0.05). Compared with I/R group, the neurological deficit scores were significantly increased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was decreased at 1 and 7 days of reperfusion in HPX group ( P<0.05), and no significant change was found in the above indicators in V and I/R groups ( P>0.05). Conclusion:Up-regulation of HPX expression is the endogenous protective mechanism of cerebral I/R injury in rats.

Objective To investigate the possibility that bone marrow mesenchymal stem cells (BMSCs) differentiated into neuron-like cells induced by ganglioside in vitro.Methods BMSCs were separated, cultured and differentiate into neuron-like cells induced by ganglioside. Neuro-specific enolase (NSE) and neurofilament (NF) on the surface of differentiated and induced BMSCs were detected by immunocytochemistry.Results BMSCs were induced to differentiate into the cells with a typical neuronal morphology. The induced neuron-like cells expressed NSE and NF.Conclusion BMSCs can be differentiated into neuron-like cells by induction of ganglioside in vitro.
