The structure of intestinal tissue is complex. In vitro simulation of intestinal structure and function is important for studying intestinal development and diseases. Recently, organoids have been successfully constructed and they have come to play an important role in biomedical research. Organoids are miniaturized three-dimensional (3D) organs, derived from stem cells, which mimic the structure, cell types, and physiological functions of an organ, making them robust models for biomedical research. Intestinal organoids are 3D micro-organs derived from intestinal stem cells or pluripotent stem cells that can successfully simulate the complex structure and function of the intestine, thereby providing a valuable platform for intestinal development and disease research. In this article, we review the latest progress in the construction and application of intestinal organoids.

Objective To observe the effect of precision nursing based on visualization technolo-gy in treating patients with pulmonary nodule surgery.Methods A total of 186 patients with surgery for pulmonary nodules were randomly divided into control group and observation group,with 93 cases in each group.The control group was given routine nursing,while the observation group was given vi-sualization technology assisted precision nursing on the basis of the control group.The psychological status[the Self-rating Anxiety Scale(SAS)score and the Self-rating Depression Scale(SDS)score]and postoperative recovery[score of the Quality of Recovery Scale with 15 items(QoR-15)]were compared between two groups,and the nursing satisfaction degree was compared between the two groups as well.Results After the intervention,the scores of SAS and SDS in both groups de-creased,and the score of each item in the observation group was significantly lower than that in the control group(P＜0.05);after intervention,the each item of the QoR-15 and the total score in the observation group were significantly higher than those in the control group(P＜0.05);the nursing satisfaction degree of the observation group was 97.8％,which was significantly higher than 89.2％in the control group(P＜0.05).Conclusion Precision nursing based on visualization technology can improve the adverse psychological state of patients with pulmonary nodule surgery,enhance the quality of postoperative recovery,and increase nursing satisfaction degree.

Objective To explore the influence of TCM emotional nursing on emotions,size of skin lesions and psoriasis area and severity index (PASI)in patients with psoriasis vulgaris.Methods A total of 86 out-patients with psoriasis vulgaris from June 201 4 to August 2015 in Longgang District Central Hospital of Shenzhen were randomly divided into control group (43 cases,decoction for cooling blood +routine nursing)and experimental group (43 cases,decoction for cooling blood +TCM emotional nursing based on seven emotions) according to random number table method.Emotions and score of PASI were compared before and 6 weeks after intervention between two groups.Results After intervention,the score of PASI was (5.44 ±0.39)in experimental group which was significantly lower than that (6.53 ±0.29)in control group (P <0.05);the proportion of active stage,rest stage,catagen was 11 .63%,32.56%,55.81 % in experimental group which were better than those (20.93%,46.51 %,32.56%)in control group with significant differences (P <0.05);the score of compulsion, somatization,interpersonal relationship,depression,terror,anxiety and total score in experimental group were lower than those in control group with significant differences (P <0.05).Conclusions TCMemotional nursing based on seven emotions has an important significance on promoting rehabilitation,relieving clinical symptoms and negative emotions in patients with psoriasis.

Objective To prepare optimization of palonosetron hydrochloride oral disintegrating tablets by orthogonal test. Methods Palonosetron hydrochloride oral disintegrating tablets were prepared with direct compression process.The content of pal-onosetron hydrochloride was determined by HPLC.The formulation was optimized with disintegration time as evaluation indices. Results The optimal formulation(60 mg/tablet)was as follows:L-HPC 12%,mannitol∶SMCC= 2∶1,magnesium stearate 2%, stevia glycosides 3%.The oral disintegrating tablets showed dine appearance and tested better;the disintegration time was 12 sec-onds;the tablets featured a hardness of 3 kg;4 min dissolution rate was 99%.Conclusion The preparation method is simple and reasonable,and the tablets can disintegrate rapidly.

There are some existing problems in controlling the quality of oxygen. In order to improve quality, efficiency and safety in the use of oxygen, we presented some factors which may give rise to variations in concentration of oxygen and proposed some suggestions based on the investigation and analysis of such problems.

Intestinal ischemia-reperfusion (I/R) is an important event in the pathogenesis of multiple organ dysfunction syndrome (MODS). The aim of this study is to determine the effects of ginsenoside Rb1 on liver injury induced by intestinal I/R in rats. Adult male Wistar rats were randomly divided into four groups: (1) a control, sham-operated group (sham group); (2) an intestinal I/R group subjected to 1 h intestinal ischemia and 2 h reperfusion (I/R group); (3) a group treated with 20 mg/kg ginsenoside Rb1 before reperfusion (Rb1-20 group); and (4) a group treated with 40 mg/kg ginsenoside Rb1 before reperfusion (Rb1-40 group). Liver and intestinal histology was observed. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) level in serum and malondialdehyde (MDA) level in intestinal tissues were measured. Myeloperoxidase (MPO), TNF-alpha, MDA level and immunohistochemical expression of NF-kappa B and intracellular adhesion molecale-1 (ICAM-1) in liver tissues was assayed. In addition, a western blot analysis of liver NF-kappa B expression was performed. Results indicated intestinal I/R induced intestinal and liver injury, which was characterized by increase of AST and ALT in serum, MDA level in intestine, MPO, TNF-alpha and MDA level and ICAM-1 and NF-kappa B expression in the liver tissues. Ginsenoside Rb1 (20, 40 mg/kg) ameliorated liver injury, decreased MPO, TNF-alpha and MDA level, NF-kappa B and ICAM-1 expression in liver tissues. In conclusion, ginsenoside Rb1 ablated liver injury induced by intestinal I/R by inhibiting NF-kappaB activation.

Cardiomyocyte hypertrophy is a major cause of morbidity and mortality worldwide. The aim of this study is to determine the effects of sodium tanshinone IIA sulfonate (STS) on cardiomyocyte hypertrophy induced by angiotensin II (Ang II) in vivo and in vitro. In long-term treatment, adult Wistar rats were infused with Ang II for three weeks via osmotic mini-pumps and some of them were given intragastrically of STS. Left ventricle was isolated; the ratio of left ventricular weight to body weight and systolic blood pressure (SBP) were determined and heart morphometry was assessed after hematoxylin and eosin staining. Results indicated STS inhibited Ang II-induced increases in myocyte diameter and decreased the LVW/BW ratio independent of decreasing systolic blood pressure. In vitro, treatment of cultured cardiomyocytes with STS inhibited Ang II-induced increase in cell size, protein synthesis, ANP expression, activation of extracellular signal-regulated kinase (ERK) and ERK kinase (MEK). Then we reexamined the mechanism of STS-induced anti-hypertrophic effects. Results revealed MEK inhibitor U0126 (20 microM) markedly enhanced STS-induced depressions in [3H]leucine incorporation and ANP expression. In conclusion, MEK/ERK pathway plays a significant role in the anti-hypertrophic effects of STS.
