Cognitive behavior, art, and music therapies intervention for treating the depression of children: A randomized control trial.

This study compared the effect of interactive media-based cognitive behaviour, art, and music therapies in reducing depression in children who survived abduction in Nigeria. A randomized control trial was conducted using three randomly selected secondary schools in Northern Nigeria. The study sample comprised 450 children randomly divided into a control group of (n = 225) and an experimental group of (n = 225). The treatment group was further divided into three groups; cognitive behavior (n = 75), art (n = 75), and music (n = 75) therapy, respectively. According to the findings of this study, cognitive behaviour, art, and music therapies via interactive media are a successful intervention technique for treating the depression of schoolchildren who survived abduction in Nigeria. However, compared to art and music therapy, cognitive behaviour therapy is more effective at treating depression. To lessen the depression of children who survived kidnapped in Nigeria, we recommend adopting cognitive behavioural therapy.

Therapeutic effects of auricular point acupressure on the recovery of patients after pterygium surgery: A pilot study.

BACKGROUND: and purpose: Postoperative pain in the pterygium of the eye seriously affects patient recovery. This study was conducted to assess the efficacy of auricular point acupressure treatment on post-operative recovery in patients after pterygium surgery. MATERIALS AND METHODS: This was a pilot, randomized controlled study. A total of 60 patients (60 eyes) were randomly assigned to two groups. After pterygium surgery, the auricular group was treated using ear acupressure (acupressure points with Cowherb seeds) and the control group was treated using sham auricular therapy (acupressure points without Cowherb seeds). Both groups were treated for one week. Outcome measures included pain score, corneal epithelial score, best-corrected visual acuity, and recurrence rate. RESULTS: Fifty-three patients completed the study. The mean pain scores and corneal epithelial scores were significantly reduced over time in the auricular group compared with those in the control group (p < 0.05). The time-group interaction for both pain scores and corneal epithelial scores was significant between the two groups (p < 0.05). Simple main effect analysis showed the mean pain scores in the auricular group were significantly lower at each time point (the first 2-h, the first day, the third day and the first week, p < 0.05) than the control group. Mean corneal epithelial scores of the auricular group were significantly lower on the first day and third day respectively than the control group (p < 0.05). There was no significant difference in the best-corrected visual acuity or recurrence rate between the two groups (p > 0.05). CONCLUSION: Auricular point acupressure accelerates corneal epithelium reconstruction and suppresses postoperative pain, making it an ideal adjunct treatment for postoperative pterygium recovery.

A semimicroquality evaluation method on Panax notoginseng and its application in analysis of continuous cropping obstacles research samples / 中国中药杂志

Panax notoginseng is a commonly used traditional Chinese medicine with blood activating effect while has continuous cropping obstacle problem in planting process. In present study, a semimicroextraction method with water-saturated n-butanol on 0.1 g notoginseng sample was established with good repeatability (RSD<2.5%) and 9.6%-20.6% higher extraction efficiency of seven saponins than the conventional method. A total of 16 characteristic peaks were identified by LC-MS-IT-TOF, including eight 20(S)-protopanaxatriol (PPT) type saponins and eight 20(S)-protopanaxadiol (PPD) type saponins. The established method was utilized to evaluate the quality of notoginseng samples cultivated by manual intervened methods to overcome continuous cropping obstacles.As a result, HPLC fingerprint similarity, content of Fa and ratio of notoginsenoside K and notoginsenoside Fa (N-K/Fa) were found out to be as valuatable markers of the quality of samples in continuous cropping obstacle research, of which N-K/Fa could also be applied to the analysis of notoginseng samples with different growth years.Notoginseng samples with continuous cropping obstacle had HPLC fingerprint similarity lower than 0.87, in consistent with normal sample, and had significant lower content of notoginsenoside Fa and significant higher N-K/Fa (2.35-4.74) than normal group (0.45-1.33). All samples in the first group with manual intervention showed high similarity with normal group (>0.87), similar content of common peaks and N-K/Fa (0.42-2.06). The content of notoginsenoside K in the second group with manual intervention was higher than normal group. All samples except two displayed similarity higher than 0.87 and possessed content of 16 saponins close to normal group. The result showed that notoginseng samples with continuous cropping obstacle had lower quality than normal sample. And manual intervened methods could improve their quality in different levels.The method established in this study was simple, fast and accurate, and the markers may provide new guides for quality control in continuous cropping obstacle research of notoginseng.

Cloning and expression studies of the Dunaliella salina UDP-glucose dehydrogenase cDNA.

The enzyme UDP-glucose dehydrogenase (EC 1.1.1.22) converts UDP-glucose to UDP-glucuronate. Plant UDP-glucose dehydrogenase (UGDH) is an important enzyme in the formation of hemicellulose and pectin, the components of primary cell walls. A cDNA, named DsUGDH, (GeneBank accession number: AY795899) corresponding to UGDH was cloned by RT-PCR approach from Dunaliella salina. The cDNA is 1941-bp long and has an open reading frame encoded a protein of 483 amino acids with a calculated molecular weight of 53 kDa. The derived amino acids sequence shows high homology with reported plants UGDHs, and has highly conserved amino acids motifs believed to be NAD binding site and catalytic site. Although UDP-glucose dehydrogenase is a comparatively well characterized enzyme, the cloning and characterization of the green alga Dunaliella salina UDP-glucose dehydrogenase gene is very important to understand the salt tolerance mechanism of Dunaliella salina. Northern analyses indicate that NaCl can induce the expression the DsUGDH.

Effects of iodine supplementation during pregnancy on child growth and development at school age.

Growth and development of 207 children (49% males; mean age 5.4 years [SD 0.2], range 4 to 7.3 years whose mothers received iodine during pregnancy, and children who received iodine first in their 2nd year, were examined in 1996; 192 children (49% males; mean age 6.5 years [SD 0.2], range 5.8 to 6.9 years) whose mothers received iodine while pregnant were seen in 1998. Children were from the southern part of China's Xinjiang Province which has the lowest levels of iodine in water and soil ever recorded. Head circumference but not height was improved for those who received iodine during pregnancy (compared with those receiving iodine at age 2) and for those supplemented before the end of the 2nd trimester (relative to those supplemented during the 3rd trimester). Iodine before the 3rd trimester predicted higher psychomotor test scores for children relative to those provided iodine later in pregnancy or at 2 years. Results from the test for cognitive development resulted in trend only differences between those children supplemented during pregnancy versus later. The results address the question of when maternal iodine supplements should begin in public health programs world wide. Findings may be relevant to the treatment of maternal and newborn thyroid deficiency in industrialized countries, particularly for those infants delivered before the end of the second trimester.
