1.Tissue-engineered skin constructed by adipose-derived stem cell sheet
Chinese Journal of Tissue Engineering Research 2014;(33):5361-5365
BACKGROUND:Wtih hyaluronic acid and col agen by cellautocrine as endogenous scaffolds, cellsheet technology can eliminate the disadvantages of exogenous scaffolds. Human adipose-derived stem cells combined with cellsheet technology used in the study of ful-thickness skin defects have become the current hot spot.
OBJECTIVE:To summarize the research progress in adipose-derived stem cellsheet.
METHODS:Articles related to adipose-derived stem cells, cellsheet technology and tissue-engineered skin were retrieved in VIP information and PubMed database from January 1993 to April 2014. The key words were“adipose-derived stem cell, wound healing, tissue-engineered skin, cellsheet”in English and Chinese, respectively. Total y 27 relevant articles were analyzed.
RESULTS AND CONCLUSION:Adipose-derived stem cells derived from discarded human adipose tissue are immmunocompatible and multi-potent, rendering them ideal for regenerative medicine applications. cellsheet technology seemingly provides several advantages over traditional tissue reconstruction with biodegradeable scaffolds. Adipose-derived stem cells combined with cellsheet technology can enhance tissue vascularization, promote wound healing, the secreted extracellular matrix provides the microenvironment for the celldifferentiation and growth, so it is expected to build a real three-dimensional tissue-engineered skin.

China Journal of Chinese Materia Medica 2014;39(2):171-174
As traditional Chinese medicine components have become a hotspot in the field of traditional Chinese medicine study, they have followed a development trend of diversity and false identification. In studies on a new modem product, we shall encourage the diversified development mode, but avoid the false concept identification of traditional Chinese medicine components. In this paper, by analyzing the current development of traditional Chinese medicine components and problems, we discussed the standardization of traditional Chinese medicine components, with the aim of reducing and avoiding the situations to study non-traditional Chinese medicine components as traditional Chinese medicine components.

3.Efficacy on depression in breast cancer treated with acupuncture and auricular acupressure.
Chinese Acupuncture & Moxibustion 2014;34(10):956-960
OBJECTIVETo compare the efficacy difference in treatment of depression in breast cancer between the combined therapy of acupuncture and auricular acupressure and western medication.
METHODSSixty patients were randomized into an observation group and a control group, 30 cases in each one. In the observation group, the combined therapy of acupuncture and auricular acupressure was adopted. The main acupoints of acupuncture were Hegu (LI 4), Tai-chong (LR 3), Baihui (GV 20), Zusanli (ST 36), Qihai (CV 6), etc. The supplementary acupoints were combined according to the syndrome differentiation. The treatment was given once every day, 5 treatments a week, at the interval of 2 days among weeks. The auricular acupressure was applied to gan (CO12, liver), pi (CO13, spleen), neifenmi (CO18, endocrine), etc., once every 4 days, on each side in one treatment. In the control group, fluoxetine hydrochloride capsules were prescribed for oral administration, 20 mg, once a day. The Hamilton depression rating scale (HAMD) was used to assess the disease severity and efficacy before treatment, in 4 and 8 weeks of treatment separately. HAMD factor changes were observed before treatment and at the end of the 8th week. The Asberg antidepressants scale (SERS) was applied to safety assessment.
RESULTSThe total effective rate was 86.7% (26/30) in the observation group, better than 63.3% (19/30) in the control group (P<0.05). At the end of the 4th and 8th weeks, HAMD scores were all reduced apparently in the two groups (all P<0.01). At the end of the 8th week, the scores of the HAMD factor 1 (anxiety/somatic system), factor 5 (retardation) and factor 6 (sleep disturbance) were all reduced as compared with those before treatment in the two groups (all P<0.01); the results in the observation group were better than those in the control group (P<0.05, P<0.01). SERS score in the observation group was lower obviously than that in the control group (P<0.01).
CONCLUSIONThe combined therapy of acupuncture and auricular acupressure achieves the antidepression effect in treatment of depression in breast cancer and has less side effects and high safety. The efficacy is superior to fluoxetine hydrochloride capsules.

Objective To understand the overall under-reporting of cause of death monitoring in Hainan Province, and to provide a scientific basis for evaluating the data from death registration report and health planning in Hainan. Methods Multi-stage cluster random sampling was used, all towns/streets in cities and counties of the province were ranked from highest to lowest in terms of crude death rate, divided into high, medium and low levels (the number of each level was basically the same), and one was randomly selected from each level. A total of three towns/streets were used as survey areas, and all households in the area were survey households. Death information of resident population during 2018-2020 was collected and compared with routine surveillance data for the same period. The under-reporting rate was calculated, and comparison between groups was performed by chi-square. Results A total of 12 583 death cases were investigated from 2018 to 2020, and the average mortality was 621.48/105. 4 809 cases were missed with the total under-reporting rate of 38.22%. The under-reporting rate from 2018 to 2020 were 39.75%, 39.99% and 34.77% (χ2=30.404, P<0.01) respectively. The under-reporting rate in eastern and central and western areas were 30.33%, 30.10% and 60.15% (χ2=931.901, P<0.01) respectively. The negative rate were different in different years old group (χ2=14.834, P<0.05). Of the 4 809 under-reported cases, as many as 93.49% died at home, and the composition of deaths in hospitals was about 10 times higher in the center than in the east and west, and the proportion of those who died in hospital in central areas was about 10 times higher than in eastern and central areas. Conclusions More than half of the cities and counties in Hainan Province have improved the completeness of cause of death surveillance data. The under-reporting rate in age group <5 years are still high, and regular under-reporting investigations are still needed to strengthen the reporting and management of death information.

Astragalus polysaccharides was lounded to 4-(2-aminoethylphenol), followed by labeling the APS-Tyr with fluorescein-5-isothiocyanate (FITC) at the secondary amino group. The absorption enhancement effects of low molecular weight chitosan and protamine on astragalus polysaccharides were evaluated via Caco-2 cell culture model. The results show that the fluorecent labeling compound has good stability and high sensitivity. On the other hand low molecular weight chitosan and protamine also can promoted absorption of the astragalus polysaccharides without any cytotoxity, and the absorption increase was more significant with increasing the amount of low molecular weight chitosan and protamine. At the same time, the low molecular weight chitosan has slightly better effect. The transepithelial electric resistance (TEER) of Caco-2 cells show that absorption enhancers could improve its membrane transport permeability by opening tight junctions between cells and increasing the cell membrane fluidity.
