Conclusion Total quality will drop along with the postponement of grow-seedling stage, transplanting stage, and collecting stage.

Objective To compare the effect of different cryoprotectants and different concentrations on controlled?rate freezing of human ovarian tissues. Methods Ovarian tissues were sampled from 15 patients undergoing benign ovarian tumor surgery. Cortical slices were frozen by controlled?rate freezing using three cryoprotectants,propanediol,ethanediol,and dimethylsulphoxide,and the concentration of each cryoprotectant was 1.5 mol/L or 2.0 mol/L. Cortical slices obtained from each patient were processed with each cryopreservation procedure simultaneously. Morphology of fol?licles was studied by light and electron microscopy and the normal rate was compared with that of the fresh tissues from the patient. Results There were no significant differences in distribution of follicles of different developmental stages between each group(P<0.05). Light microscopy showed 1.5 mol/L EG and 2.0 mol/L EG groups had the best freezing effect,and the difference in the morphologically normal rate of follicles was not statisti?cally significant compared to fresh controls(P>0.05). However,the difference was statistically significant for 1.5 mol/L PROH,2.0 mol/L PROH, 1.5 mol/L DMSO and 2.0 mol/L DMSO groups(P<0.05). Electron microscopy showed the oocyte quality declined after controlled?rate freezing pro?cedure. However,the statistical analysis was not conducted due to little data. The viability of granulosa cells was significantly declined after all the freezing procedures compared to that of the fresh control tissues(P<0.01). The number of morphologically normal granulosa cells was slightly higher in the tissues which had been cryopreserved with 2.0 mol/L PROH and 1.5 mol/L EG,but no significant differences were found between any of two frozen groups(P>0.05). Conclusion Controlled?rate freezing using 1.5 mol/L EG as the cryoprotectant can better save oocytes and granulosa cells. It is a preferable freezing procedure for ovarian tissues.

Background and purpose:A variety of measures are taken preoperatively to reduce the tumor size of stageⅠb2 bulky cervical cancer before surgery. Which one is safer and more effective, currently, there is no consensus. This article compared the effect in 3 different treatment methods (neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy and operation) on patients with stageⅠb2 bulky cervical cancer, and provided evidence for clinical decision. Methods:Retrospective analysis the clinical date of 133Ⅰb2 bulky cervical cancer patients, who received preoperative neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy and direct operation from Apr. 2006 to Oct. 2010 in our hospital. Results: The effective rates of neoadjuvant chemotherapy, neoadjuvant chemoradiotherapy group were 91.8% and 92.5%, respectively, there was no statistical difference(P>0.05). The tumor size got smaller after treatment compared with the size before treatment (P<0.05);The pathological efifciency rates were 95.56%and 97.30%, respectively, the difference was not statistically significant (P>0.05). The bleeding volume of neoadjuvant chemo radio therapy group was significantly higher than those in the other 2 groups (158.9±50.7 vs 116.8±45.5, 123.1±30.2;P<0.05), the infection of immediate surgery group was more severe than the other 2 groups (P<0.05). The pairwise comparison of average operation time in neoadjuvant chemotherapy group, neoadjuvant chemoradiotherapy group, and the immediate surgery group, pairwise comparisons of neoadjuvant chemotherapy group and the immediate surgery group in bleeding, comparion of neoadjuvant chemotherapy group and neoadjuvant chemoradiotherapy group on postoperative infection, and the comparison of the 3 groups on pelvic organ injury and lymphocele, had no statistical difference(P>0.05);Pathological examination showed that vascular invasion in surgery group had statistical differences than other 2 groups (P<0.05), there was no patient with positive margin in the 3 groups, and the lymph node metastasis rates also had no statistical difference (P>0.05);Besides, there were no statistical difference on vascular invasion between the 3 groups (P>0.05);And on 3-year overall survival, disease-free survival there was no statistical difference between the 3 groups (P>0.05). Conclusion:Neoadjuvant chemotherapy can effectively reduce tumor size for patients with stage Ⅰb2 bulky cervical cancer before operation, it is better than direct surgery or preoperative chemoradiotherapy in improving the resection rate, and reducing postoperative pathological positive rate, and infection. Neoadjuvant chemotherapy can improve the pathological complete remission rate. The combination of radiation and chemotherapy might produce synergistic effect on huge cervical tumor, but it can’t improve the survival rate. Therefore, neoadjuvant chemotherapy is the best choice for the stageⅠb2 cervical cancer patients. Therefore, a long-term follow-up or large sample randomized controlled trials is necessary to assess the prognosis of preoperative neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy.

BACKGROUND:There are myoblasts in human embryonic skeletal muscle. It remains poorly understand whether myoblasts in vitro can form myotube and what are the corresponding markers for identifying myoblasts and myotubes. OBJECTIVE:To investigate whether in vitro cultured myoblasts from human embryonic skeletal muscle can form myotube and whether they can express neural markers. METHODS:Human embryonic muscle-derived myoblasts were cultured in serum-containing medium. When the primary culture was established, cultured cel s were identified with immunocytochemistry for neural markers, such asβ-tubulin markers (desmin, myogenin, smooth muscle actin and myosin). RESULTS AND CONCLUSION:A population of myoblasts could migrate from human embryonic muscle tissues. They could express the markers for skeletal muscle such as desmin and myogenin, and they could express neuron specific enolase, nestin and neurofilament 200. They could form myotubes in vitro, and myotubes expressedβⅢ-tubulin, neurofilament 200 and glial fibril ary acidic protein. The data support the hypothesis that myoblasts from human embryonic muscle express neural markers and muscle markers, and cultured myoblasts and myotubes expressed neuron specific enolase,β-tubulin Ⅲ, nestin, neurofilament 200 and glial fibrillary acidic protein. This indicates that these markers could not be used for cel identification of trans-differentiation study from muscle origin to nervous system.

BACKGROUND:Human skin-derived precursors can be cultured for a long term in vitro, and differentiated into neurons, glial cel s, smooth muscle cel s, Schwann cel s and cel s with peripheral neurons phenotype.
OBJECTIVE:To investigate the culture conditions and multiple differentiation capacity of multipotential stem cel s from human skin, especial y the potentials of differentiating into neurons and osteoblasts.
METHODS:Human skin-derived precursor cel s were cultured with trypsin digestion method, and identified with immunocytochemistry. Cel s at passages 3-4 were induced to differentiate into neurons and osteoblasts, and underwent von Kossa staining protocol for calcium, chondrocyte induction, toluidine blue staining, immunohistochemical staining and Sudan black staining. The expression of nestin, vimentin,βIII-tubulin, S100 and col agen II in the human skin-derived precursors was detected.
RESULTS AND CONCLUSION:The human skin-derived precursor cel s cultured with trypsin digestion method could proliferate and form suspending spheres, and nestin positive cel s were detected at any time point of the culture. Al the cultured cel s expressed vimentin, and some adherent cel s expressedβIII-tubulin. Human skin-derived precursor cel s were induced with Salvia miltiorrhiza to differentiate into neuron-like cel s, and expressed marker of nerve cel s. Skin-derived precursors could be induced to differentiate into osteoblasts and von Kossa staining displayed black calcified nodules in the culture dish. Skin-derived precursors could also be induced to differentiate into chondrocytes, and toluidine blue staining was strongly positive, and some cel s expressed col agen II, which suggested that, the differentiated cel s contained chondrocytes. Experimental findings indicate that, skin contains multipotential stem cel s that are capable of differentiating into osteoblasts, chondrocytes, Schwann cel s and oligodendrocytes.

Objective To investigate the prevalence and correlation factors of cardiovascular damage in patients with diabetic nephropathy (DN) and non-diabetic nephropathy (NDN).Methods A total of 278 chronic kidney disease (CKD) patients admitted to the First Affiliated Hospital of Jinan University from January 2014 to May 2016 were enrolled,including 78 case of DN and 200 case of NDN.Patients had cardiac and carotid ultrasonography test by colour doppler ultrasonography,and their clinical and biochemical data were collected.Multiple linear regression analysis and multivariable logistic regression analysis were applied to study the correlation factors of cardiovascular damage in CKD patients.Results Mean age was 48.22 years in the 278-patient cohort,which included 178(64.03％) men.Compared with NDN group,DN patients had higher left atrial dimension,interventricular septal thickness,left ventricular end-diastolic dimension,left ventricular posterior wall thickness,left ventricular mass index (LVMI),carotid intima-media thickness (cIMT) and carotid plaques ratio.Their estimated glomerular filtration rate (eGFR) and the ratio between the peak speed of the early filling wave and that of the atrial contraction wave (E/A ratio) were however lower (all P ＜ 0.05).Prevalence of left ventricular hypertrophy (LVH),left ventricular relaxant function reduction and cIMT thickening in DN group were 67.95％,70.27％ and 57.14％,higher than those in NDN group (40.00％,42.31％ and 17.39％,respectively) (all P＜ 0.05).Along with the progress of CKD,LVMI and LVH proportion in patients with DN and NDN increased gradually.LVMI and LVH proportion in DN patients in CKD 1-2 phase and CKD 3-4 phase were higher than those in NDN patients (all P ＜ 0.05).In all CKD phases,cIMT and cIMT thickening proportion in DN group were higher than those in NDN group (all P ＜ 0.05).Just in CKD 1-2 phase,DN group had lower E/A ratio and higher proportion of left ventricular relaxant function reduction than NDN group (all P ＜ 0.05).After multiple linear regression analysis,gender,BMI,hemoglobin,eGFR and DN were related with LVMI;age,serum calcium and DN were related with E/A ratio;age and DN were related with cIMT (all P ＜ 0.05).In multivariate logistic regression,DN,hemoglobin and eGFR decrease were independently associated with LVH;age and BMI were independently associated with reduction of left ventricular relaxant function;age and DN were independently associated with cIMT thickening in all CKD patients (all P ＜ 0.05).Conclusions DN patients have more severe cardiovascular damage than NDN patients,and DN may be associated with LVMI,E/A ratio,cIMT,LVH and cIMT thickening in all CKD patients.

Objective To apply sandplay therapy in cerebral palsy children's parents for the psychological problems. Methods 40 parents of cerebral palsy children were randomly divided into experimental group (n=20) and control group (n=20). The experimental group accepted sandplay therapy once a week for 10 weeks, and the control group without any intervention. All the parents were assessed with Symptoms Check-List 90 (SCL-90), Self-Esteem Scale (SES), compliance questionnaire, Quality of Life Questionnaire-Core 30 (QLQ-C30) before and after the experiment. Results The scores of all the factors of SCL-90 were lower in the experimental group than in the control group (P<0.05), with the higher scores of compliance and self-esteem (P<0.05), and the high quality of life in physical function, role in work and social function (P<0.05) in the experimental group. Conclusion Sandplay therapy can be used to solve the psychological problems of cerebral palsy children's parents, and improve their compliance, self-esteem and quality of life.

Objective To evaluate treatment effect of nodal lymphoma by using multiple b value diffusion-weighted MRI based on intravoxel incoherent motion (IVIM) model. Methods From November 2012 to November 2013, 22 patients with pathology confirmed lymphoma in Guangdong General Hospital were chosen. Patients were examined on a 1.5 T MR scanner with plain MRI scan and multiple b value diffusion-weighted MRI scan before and after cycle two of chemotherapy. According to chemotherapy response which evaluated after cycle 2 of chemotherapy, lymphoma nodes were divided into four groups:complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD). Kruskal-Wallis H test was used to compare prechemotherapy D value, f value among CR, PR, SD groups. Nemenyi test was used to compare prechemotherapy D value between the two of CR, PR, SD groups. One-way ANOVA was used to compare D*value among CR, PR, SD groups. Paired-sample t test was used to compare D, f, D*value between before and after chemotherapy in PR group. CR and PR group were ascribed to curative group, and SD group ascribed to poor response group. ROC curve was used to evaluate the predictive efficiency of parameters derived from IVIM. Results Twenty-two lymphoma patients were scanned before chemotherapy and 21 patients were scanned after cycle 2 of chemotherapy. There were 49 lesions in CR group, 17 lesions in PR group, 8 lesions in SD group and no lesions in PD group. Prechemotherapy D value of CR, PR, SD group were (0.63±0.26)×10-3, (0.57±0.10)×10-3,(0.42±0.04)×10-3 mm2/s, respectively. There was significant difference among the three groups (H=12.944,P=0.002). There was no statistically difference of prechemotherapy D value between CR and PR group (χ2=0.072,P=0.965). Prechemotherapy D value was lower in SD group than that in CR group (χ2=12.090,P=0.002) and PR group (χ2=10.684,P=0.005). There was no statistically difference of prechemotherapy f value among CR, PR, SD groups (χ2=2.312,P=0.315) or D*value (F=0.535,P=0.588). D value significantly increased after chemotherapy in PR group [(1.03±0.37)× 10-3 vs.(0.63 ± 0.26)× 10-3 mm2/s, t=-4.781, P=0.001]. f value significantly increased after chemotherapy in PR group [(9.39 ± 4.52)% vs.(6.44 ± 3.25)%, t=2.294, P=0.036]. D* value slightly increased after chemotherapy but with no statistical difference in PR group [(99.72 ± 42.12)× 10-3 vs.(90.37 ± 45.33)× 10-3 mm2/s, t=-0.579, P=0.570]. When a D value of 0.48 × 10-3 mm2/s was used as the threshold value for predicting chemotherapy response, the best results were obtained with sensitivity of 100.00%and specificity of 75.76%.Conclusions Prechemotherapy D value can predict chemotherapy response and D value can monitor chemotherapy response in lymphoma.
