Objectives To study the correlation between social emotion and temperament in infants and toddlers. Me-thods The Brief Infant-Toddler Social and Emotional Assessment (BITSEA) and Toddler Temperament Questionnaire (TTQ) were used to evaluate the social emotional problems and temperament of 657 infants and toddlers 1 to 3 years old. Results The temperament dimensions were correlated with behavior and competence factors. The infants and toddlers in dififcult type group had more behavior problems or deifcits/delays in competence than those in easy type group (χ2=26.49, 10.48, P<0.01). Conclu-sions Infants and toddlers with negative temperament traits have more behavior problems and weaker social emotional compe-tences. The temperament should be considered in dealing with emotional problems.

Rectal cancer is a common malignant tumor in the gastrointestinal system.For the patients with resectable but high-risk rectal cancer,neoadjuvant and adjuvant chemoradiation plus surgery may improve local control.Compared to adjuvant chemoradiation,neoadjuvant chemoradiation showed the advantage of sphincter preservation.When the goal of preoperative chemoradiation was sphincter preservation,conventional radiotherapy was recommended.Through the analysis of the patients with 5-year survivals,the radiation had a similar impact on the survival as the chemotherapy alone for the patients with the intermediate risk factors.The impact on local control need to be further investigated before recommending chemotherapy alone for those subset patients.Advances in preoperative irradiation,postoperative irradiation and the comparison of preoperative irradiation with postoperative irradiation are also reviewed in this article.

Objective To investigate the significance of blood donation in preventing metabolic syndrome (MS)by analyzing the changes of the blood pressure and the related biochemical indexes before and after blood donation in the blood donors with high risk of MS.Methods The blood specimens of 102 blood donors,aged 45 -55 years old with the systolic blood pressure of 110 -140 mmHg and the diastolic blood pressure of 75 -90 mmHg,the body mass index> 24 kg/m2 ,were selected as the subjects.The blood pressure,heart rate,iron reserves,blood glucose,blood lipids,and the other indicators were determined before blood donation. All the above indicators were tested again on 42 d after blood donation.Results The blood pressure,iron reserves,blood glucose and LDL/HDL ratio after donation showed significant changes compared with before blood donation(P <0.05 ).Conclusion The changes of the MS related blood indexes exist before and after blood donation,blood donation has a certain significance for preven-ting MS in the blood donors with high risk of MS.

OBJECTIVE:To explore the ways of preventing errors in the process of drug treatment.METHODS:Related overseas literatures were consulted;causes of errors in the drug treatment were analyzed,which combined with prac-tice.RESULTS&CONCLUSIONS:Errors can be found effectively and reduced by establishing independent checking and error reporting system.

BACKGROUND:Due to quantity and quality deficiencies, chondrocytes from microtia are difficult to act as seed cells to construct an ear cartilage scaffold with the normal human auricle size. OBJECTIVE: To test the hypothesis that auricular chondrocytes from microtia can promote chondrogenic differentiation and chondrogenesis of human adipose tissue-derived stem cells (ADSCs) at non-chondrogensis sitein vivo, which is the preparatory work for preparation of human tissue-engineered auricle cartilage scaffold. METHODS: Human ADSCs at passage 3 and auricular chondrocytes at passage 2 were mixed at a ratio of 7:3 and 5.0×1010/L mixed cells were suspended in 0.2 mL of 30% Pluronic F-127, and then the mixture was injected subcutaneously into Balb/c nude mice as experimental group. Auricular chondrocytes or ADSCs at the concentration of 5.0×1010/L were mixed with 0.2 mL of Pluronic F-127 and injected respectively as positive and negative control groups. 1.5×1010/L auricular chondrocytes were mixed and injected as low-concentration chondrocyte control group. All specimens were collected at the 8th week post-injection. Newborn tissues in nude mice were taken out for morphological examination, wet weight measurement, determination of glycosaminoglycans, histological and immunohistochemical staining. RESULTS AND CONCLUSION:The wet weight of specimens in the experimental group was over 80% of that in the positive control group, and the wet weight of specimens in the low-concentration chondrocyte control group was less than 30% of that in the positive control group. The average wet weight and glycosaminoglycan content were significantly higher in the experimental and positive control group than in the negative control and low-concentration chondrocyte control groups (P < 0.05). In all the groups except for the negative control group, mature cartilage lacunas could be observed by histological staining and collagen type Ⅱ could be detected for expression by immunohistochemistry to different extents. In the low concentration chondrocyte control group, cartilage lacunas were incompact and inhomogeneous, and the extracellular matrix was slightly stained. In the negative control group, mature cartilage lacunae and collagen type Ⅱ could not be detective. To conclude, auricular chondrocytes from microtia can promote chondrogenic differentiation and chondrogenesis of ADSCs at the non-chondrogenesis sitein vivo.

Usually individualized comprehensive treatments are applied to children with cerebral palsy. Among them, Kinesio taping is a simple treatment compared to orthosis, which allows greater rang of motion (ROM) and can more easily be accepted by patients, however, its effectiveness is controversial. This article introduced the mechanism that mainly includes relieving pain, improving joint mobility, increasing strength, relieving edema and increasing proprioception. The application of it in upper limbs, lower limbs and trunk of children with cerebral palsy was discussed. Finally, the advantages and limitations of Kinesio taping, suitable types of cerebral palsy and the therapeutic evaluation were analyzed.

Objective To explore the feasibility of hand-assisted laparoscopic splenectomy and azygos-portal disconnection. Methods Hand-assisted laparoscopy was performed in 12 patients with hypersplenia secondary to post-hepatitic hepatocirrhosis and a history of rupture and bleeding of esophago-gastric varicose vein.An ultrasound knife was used to dissect the ligaments of the spleen.The Endo-Cutter was used to cut off the pedicle of the spleen.Then the spleen was removed in a plastic bag.All of the varicose vessels around the fundus and the lower segment of the esophagus(6~8 cm in length) were dissected and disconnected according to the criteria of open surgery.Results The operation was successfully completed in 10 patients,while conversions to open surgery were required in 2 patients because of massive hemorrhage during the operation.The operating time was 2.5~5 h(mean,3.4 h) and the hemorrhagic volume was 100~500 ml(mean,250 ml).Postoperatively,1 patient experienced an intraperitoneal hemorrhage and received open surgery for hemostasis while the remaining patients had an uneventful recovery without complications.A total of 10 patients were followed for 0.5~2 years(mean,1.5 years).Four patients died of liver failure.Six patients presented small volumes of relapsed upper gastrointestinal bleeding around 1 year after operation.Gastroscopy showed portal hypertensive gastropathy in 3 patients,gastric ulcer in 1 patient,and ruptured varicose esophageal veins in 2 patients.All the 6 patients were cured by conservative medical treatment.Conclusions Hand-assisted laparoscopic splenectomy and azygos-portal disconnection is a feasible,effective,and safe surgical procedure.
