A total of 218 patients on chemotherapeutic regimens containing oxaliplatin were randomly divided into experimental (n =120) and control (n =98) groups.The experimental group received an intravenous infusion of lipoic acid plus sodium potassium magnesium calcium and glucose injection.The control group had only normal saline.Overall incidence of neurotoxicity and toxicity grade of peripheral nerve were observed after 4,8 and 12 cycles.Those with neurotoxic symptoms were followed up for 1 year.No significantly statistical difference existed in the incidence of peripheral neurotoxicity after 4,8 cycles (P ＞0.05).After 12 cycles,31 patients in the experimental group had an onset of neurotoxicity of grade3 (n=8,6.7％) &grade4 (n=0) versus21 cases of grade3 (n=21,21.4％) and grade4 (n=5,5.1％) in the control group.Statistically significant differences existed between grades 3 and 4 neurotoxicity (P ＜0.05).After 1 year of follow-up,the incidence of grade 1 of neurotoxicity was 2.5％ (n =3) in the experimental group versus 23.7％ (n =9) in the control group.And the inter-group difference was statistically significant (P ＜ 0.05).Lipoic acid plus sodium potassium magnesium,calcium and glucose injection can effectively prevent the occurrences of acute and chronic peripheral neurotoxicity associated with oxaliplatin.

Objective By combining the traditional Chinese medicine(TCM) health care service and the current community puerperal women's health management, to explore the feasibility of TCM health management in the grass-roots community on puerperal women’s breast-feeding. Methods 440 patients meeting the inclusion criteria of puerperal women according to the neighborhood of residence were recruited into a non TCM intervention group of 225 people, and a TCM intervention group of 215 people. The non TCM intervention group was given health guidance on puerperal women. On such basis, the TCM intervention group was further cooperated with appropriate technical guidance of TCM. Puerperal women breastfeeding before and after the intervention was studied. Results After the intervention, the milk shortage of puerperal women breastfeeding rate of TCM intervention group was higher than the non TCM intervention group, 76.9% (60/78) vs. 56.9% (41/72), and mixed feeding rate was lower 21.8% (17/78) vs. 40.3%(29/72), the difference was statistically significant (χ2=5.916, 5.178; P < 0.05). The rate of breast feeding and mixed feeding rate were also statistically different between the TCM intervention group and the non TCM intervention group 78.1%(168/215) and 17.2% (37/215) vs. 62.7% (141/225) and 33.3% (75/225), (χ2=11.860, 14.226; P<0.01). Conclusion TCM health management guidance on puerperal women in the community can effectively improve the hypogalactia puerperal women's breastfeeding rate.

OBJECTIVETo investigate the significance of beta-adrenergic receptor 2 (beta2-AR) and vascular endothelial growth factor-2 (VEGFR-2) in the occurrence and development of infantile hemangioma through detecting the expression of beta2-AR and VEGFR-2 in the different stages of infantile hemangiomas.

METHODSAccording to the Mulliken's classification standard, we classified the specimens as proliferating group (32 cases), involuting group (17 cases) and involuted group (11 cases). Normal skin tissue surrounding the hemangioma from 7 cases were chosen as control group. The expression of beta2-AR and VEGFR-2 was detected by immunohistochemical technique in proliferating hemangioma, involuting hemangioma, involuted hemangioma. The mean optical density was measured by image analysis system (Image Pro Plus 6.0) and SPSS 16.0 software was applied for statistical analysis.

RESULTSThe expression of beta2-AR and VEGFR-2 was strongly positive in proliferating hemangioma, while positive in involuting hemangioma and weakly positive in the involuted stage. The mean optical density of each phase was 0.064 751 2 +/- 0.012 747, 0.031 6017 +/- 0.006 848,0.011 869 8 +/- 0.039 349 for beta2-AR, and 0.068 940 9 +/- 0.029 274, 0.028 445 5 +/- 0.006 396, 0.011 184 1 +/- 0.004 198 for VEGFR-2. The differences between different stages had a statistically significance (P < 0.05). Correlation analysis on the mean optical density between beta2-AR and VEGFR-2 had a statistically significance (P < 0. 05).

CONCLUSIONSBeta2-AR and VEGFR-2 may be involved in the occurrence and development of infantile hemangioma.

OBJECTIVETo construct and characterize the TGF-β1, induced epithelial-mesenchymal transition (EMT) model of keloid epithelial cells in vitro, and to investigate the expression of epithelial stem cells related surface markers in keloid epithelial cells during EMT induction.

METHODSThe epithelial cells from 3 keloid samples of ears were cultured in vitro and induced by transforming growth factor betal (TGF-β1, 1 ng/ml) for 5 days, which was the experimental group, the same cells untreated were considered as the negative control group. The expressions of EMT-associated markers and regulative genes were detected using immunofluorescence staining, real-time PCR and western blot analysis. Then the surface markers of epithelial stem cells were detected using real-time PCR. Statistical significance was determined using Independent-Samples t Test, a p value less than 0. 05 was considered statistically significant.

RESULTSThe mRNA expression of transcription factor snail2 and mesenchymal-specific marker vimentin increased significantly in TGF-β1, induced keloid epithelial cells (P < 0. 05), in which snail2 increasing from 0. 91 ± 0. 23 to 1. 69 ± 0. 10, and vimentin from 5. 86 ± 2. 07 to 24. 29 ± 5. 39. Whereas the mRNA expression of epithelial-specific marker E-cadherin decreased from 1. 06 ± 0. 19 to 0. 65 ± 0. 09. The mRNA expression of CD29 and Lgr6, two surface markers of epithelial stem cells, significantly increased after induction of the TGF-β1, (P < 0. 05), from 0. 55 ± 0. 14 and 1. 61 ± 0. 31 to 1. 19 ± 0. 12 and 3. 84 t 0. 62 respectively. In induced cells, the immunofluorescence results showed staining of E- cadherin became faint, but the number of positive staining cells of vimentin increased. Western blot confirmed the protein expression of E-cadherin weakened, and the vimentin and p-Smad3 enhanced (P < 0. 05).

CONCLUSIONSTGF-β1, initiated EMT in keloid epithelial cells by inducing the up-regulation of snail2, and TGF-β1,/Smad3 signaling pathway was involved in EMT. EMT could change the phenotype of epithelial stem cells in keloid.

Objective To analyze the cerebral autoregulation capability in patients with chronic insomnia disorder (CID).Methods Sixty CID patients (54 with generalized anxiety disorder) and 40 healthy controls were enrolled in this study.Polysomnography was done in all the participants.Noninvasive continuous cerebral blood flow velocity of bilateral middle artery and arterial blood pressure were recorded simultaneously using transcranial Doppler and a servo-controlled plethysmograph.Transfer function analysis was used to derive the autoregulatory parameters, including phase difference and coherence function.Results The phase difference values of CID patients with generalized anxiety disorder were significantly lower than that of the healthy controls ((46.89±15.39)°vs (56.00±12.05)°, t=3.439, P=0.001).In the correlation analysis, we further found that there was no correlation among phase difference values and the score of Hospital Anxiety and Depression scale.Conclusions The dynamic cerebral autoregulation was compromised in CID patients with generalized anxiety disorder regardless of the degrees of anxiety and depression.Dynamic cerebral autoregulation may be a potential therapeutic target in improving neurological symptoms in patients with CID.

To investigate and summarize the characteristics of mass media reports about medical disputs, and to analyze how the reports impact public perception and behaviors, and finally to propose some suggestions. A total of 385 people were conveniently randomizedly sampled to the survey, including 280 citizens in Beijing and 105 netizens. The results showed reporting modes by the mass media were diversified, and their truthfulness was various. Among them, 63.56% people thought the mass media reporting “medical disputs” almost supported the truthfulness, while 23.29% thought the mass media lacked truthfulness, because the format of the mass media reporting was fast speed rather than good quality. A total of 98.63% people thought the mass media has an impact on the public perception and behaviours, where 69.36% supported their positive aspects, while 30.64% showed negative. Based on the views above, it’s found that the mass media lacked right information of medicine. Therefore, in order to make a harmonious condition of doctor-patient relationship, it’s necessary to truly report the news with a scientific view, to build a platform for the information exchanges between hospitals and media, and to strengthen the social supervision and management.

Objective To investigate the protective effects of rhein lysinate (RHL)on the blood vessel damage induced by oxidative stress in the mice,and to explore its mechanism.Methods The mouse models of oxidative damage were established by intraperitoneal injection of paraquat.30 C57 mice were randomly divided into control, paraquat model,and RHL prevention groups.The mice in RHL prevention group were given RHL by gavage for one week before performing model.The mice in other two groups were given equal volume of distilled water.For making model,paraquat was intraperitoneally injected in the mice in paraquat model and RHL prevention groups once a week for two weeks.The activities of superoxide dismutase (SOD)and glutathione peroxidase (GSH-Px) and the content of serum malonaldehyde (MDA) of the mice were detected 2 weeks after modeling. The pathological profile of blood vessel was observed by hematoxylin and eosin (HE)staining and the level of reactive oxygen species was observed by DCFH-DA staining.The expressions of genes related to blood vessel damage were detected by Western blotting method.Results Compared with control group,the activities of SOD and GSH-Px were decreased and the content of MDA was increased in paraquat model group (P < 0.05 ). Compared with paraquat model group,the activities of SOD and GSH-Px were increased and the content of MDA was decreased in RHL prevention group (P <0.05).The pathological examination indicated the structure of blood vessel of the mice was damaged and the level of reactive oxygen species of blood vessel was increased (P <0.05)in paraquat model group.The pathological changes were significantly improved and the level of reactive oxygen species of blood vessel of the mice was decreased (P < 0.05 )in RHL prevention group. The Western blotting analysis showed that compared with control group,the expression levels of nitric oxide endothelial synthase (eNOS)and caspase-3 of the mice in paraquat model group were decreased (P < 0.05),however the expression level of cleaved fragment of caspase-3 was increased (P < 0.05).Compared with paraquat model group,the expression levels of eNOS and caspase-3 of the mice in RHL prevention group were increased (P < 0.05 )and the expression level of cleaved fragment of caspase-3 was decreased (P <0.05).Conclusion Paraquat could induce vascular cell damage in vivo through increasing the levels of reactive oxygen species, and RHL could antagonize the effects of paraquat by scavenging reactive oxygen species, and up-regulating the eNOS expression and reducing the expression of the cleaved fragment of caspase-3.

Objective To assess the effectiveness and safety of propranolol in infantile hemangiomas by comparing with prednisone.Methods A systematic literature search of PubMed,Embase,Cochrane,Ovid,Google Scholar and CNKI,VIP,Wanfang database was conducted to identify studies about the treatment of propranolol in children with hemangiomas.We chose randomized controlled trials and clinical controlled trials.We selected literatures by certain standards.Results Eight papers including 9 studies were identified by the strategy mentioned above.These 8 literatures met our inclusion criteria after review by two independent reviewers.The studies comprised 407 patients.Six of the control group were oral prednisone,and there was no statistic heterogeneity (P =0.09,I2 =0％).The fixed model was used to do the statistic analysis.The outcome showed the effective rate of propranolol was higher than that of prednisone,with statistically significant difference (OR=7.56,95％ CI:3.18-17.98).Three of the control group included observation or oral placebo,without statistic heterogeneity (P=0.48,I2=0％) either.The outcome showed the effective rate of propranolol on hemangioma was higher than that of the control group (OR=23.15,95％CI:7.15-74.94).Of all the eight researches,five reported adverse effects,with statistic heterogeneity (P=0.0003,I2 =81 ％).In addition,the adverse rate of propranolol was lower than that of prednisone,with statistically significant difference (OR=0.12,95％ CI:0.02-0.75).Conclusions The results of this meta-analysis show that oral propranolol could obviously decrease the volume and improve the color of infantile hemangiomas.And propranolol is a significantly more effective for IH than steroids.The incidence of adverse effects of propranolol is also lower than that of prednisone.As a result,propranolol should be recommended as the first choice therapy for infantile hemangioma.

This study examined mothers' perceptions on nutrition education for elementary school students according to demographical factors. Questionnaires were distributed to the mothers of 511 elementary school students in the Busan area. According to the results, 50% of the respondents felt that the preschool years or the lower elementary grades were proper times to start nutrition education. Furthermore, they preferred school dietitians (55.4%), outside professional dietitians (16.3%), nurse teachers (13.8%), class room teachers (11.7%), and parents (2.8%) as nutrition educators. The mothers who were college and university graduates had significantly (p<0.001) higher scores regarding the necessity of nutrition education for student growth when compared to mothers who were high schools graduates. However, the high school graduates had significantly (p<0.001) higher scores than the college and university graduates with respect to nutrition education for correcting obesity. The order of importance for nutrition education curriculum content was as follows: eating habits, food safety, health and disease, maintaining ideal body weight, food waste and environment, basic food knowledge, and traditional foods. The college and university graduates, and those of 'A' group schools, had significantly (p<0.001) higher importance scores for proper eating habits. Mothers having experience with nutrition education comprised 43.9% of the subjects, and there was a significantly (p<0.05) higher percentage of employed mothers as compared to unemployed. Eighty-six percent of the respondents wanted to receive nutrition education. For more effective learning, they preferred in-person group education rather than correspondence education using e-mails or printed materials from schools.
