OBJECTIVETo establish a new culture method to induce the differentiation of embryonic pancreatic cells into mature endocrine cells.
METHODSMouse embryos at day 12.5 were used and embryonic pancreata were isolated. The isolated embryonic pancreata were cultured on the filter for 7 days, which floated in the dish containing medium. During culture, the expression of pancreas duodenum homeobox-1 (PDX-1), a pancreatic stem cell marker, was examined at day 1. The expression of neurogenin 3 (Ngn3), a pancreatic progenitor cell marker, was examined at day 3. The expressions of endocrine and exocrine markers, insulin, glucagon, and carboxypeptidase (CPA) were examined at day 7 by immunohistochemistry. The kinetics of pancreatic marker expression during culture was assayed by real-time PCR.
RESULTSMany pancreatic stem cells still existed in embryonic pancreata cultured for 1 day; meanwhile, these pancreatic stem cells proliferated in high rate. A large amount of pancreatic progenitor cells were found in embryonic pancreata cultured for 3 days.Pancreatic stem/progenitor cells differentiated into mature endocrine and exocrine cells in embryonic pancreata after having been cultured for 7 days. Furthermore, the expression pattern of pancreatic marker is consistent with that in vivo.
CONCLUSIONWe successfully established a new culture method, with which embryonic pancreatic cells can efficiently differentiate into mature endocrine cell.

In order to study the relationship between lengths of homologous fragments and chromsomic recombination rate in Saccharopolyspora erythraea, three homologous sequences, with mutant loci and different flanking sequences, (26bp + 27bp), (500bp + 576bp) and (1908bp + 1749bp), were synthesized by chemical reaction or PCR amplification, and cloned into pWHM3 to construct homologous recombination plasmids, pWHM1113, pWHM1116 and pWHM1119. When the plasmids were transformed into protoplast of Saccharopolyspora erythraea A226 under PEG mediated, on an average 30, 69 and 170 transformants grew on each plate for the three plasmids respectively, but chromosomic integration frequency were 0, 2% and 19% among corresponding transformants. Both pWHM1116 and pWHM1119 could take double crossover recombination, and exchange the mutant loci in the chromosome. It was concluded that when the flanking sequences were equal or more than (500bp + 576bp), they could take effective single and double recombination with Saccharopolyspora erythraea chromosome.

OBJECTIVETo explore the relationships between quality of life, negative life events, social support and suicide ideation among undergraduates in colleges.
METHODS3517 undergraduates in colleges were recruited by multistage stratified random clustered sampling method. Factors associated with suicide ideation were analyzed with logistic regression by scores of Beck Scale for Suicide Ideation(BSSI), Generic Quality of Life Inventory (GQOLI), Adolescent Self-rate Life Events Checklist (ASLEC), Social Support Rating Scale (SSRS) and a questionnaire on background information.
RESULTSThe rate of suicide ideation within 7 days was 14.1%, especially in females (15.96%), with single parent (23.79%) and disabled undergraduates (25.00%). The primary risk factors for suicide ideation were with low psychological function, material life, family/social support, lower availability of support and more negative life events.
CONCLUSIONThe prevalence of suicide ideation among these undergraduates was high, appropriate measures focusing on these risk factors should be implemented.

OBJECTIVETo investigate the association of the ATP-binding cassette sub-family G member 1 (ABCG1) gene polymorphisms with coronary atherosclerotic disease (CAD) in Chinese Han population.
METHODSA population based case-control association study was carried out in 541 patients with CAD and 649 healthy controls from Chinese Han population. Two single nucleotide polymorphisms (SNPs) of the ABCG1 gene were genotyped using polymerase chain reaction-restriction fragment length polymorphism. Logistic regression was used to compare the genotypic and allelic frequency difference.
RESULTSThe frequency of allele C of rs225374 was significantly higher in the CAD patients than that in the healthy controls (OR=1.186, 95%CI: 1.009-1.394, P=0.039), while the difference was also significant in the male subgroup (OR=1.236, 95%CI: 1.014-1.506, P=0.036). A statistically higher frequency of rs1044317 allele A was found in the CAD patients in comparison to the healthy controls (OR=1.187, 95%CI: 1.009-1.397, P=0.039). In case-only association study, rs225374 showed significant association in the high Gensini score group compared with the low Gensini score group (OR=1.303, 95%CI: 1.024-1.657, P=0.031).
CONCLUSIONThe two SNPs of the ABCG1 gene might be associated with the susceptibility and severity of CAD in Chinese Han population.

Objective: To summarize the clinical application patterns in acupuncture-moxibustion treatment of AD by reviewing the clinical literatures on acupuncture-moxibustion for Alzheimer disease (AD) published between January 2009 and December 2019. Methods: China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), Chinese Medicine Acupuncture-moxibustion Information Database, PubMed Medical Data Retrieval Service System, Springer Database and Ovid Technologies (OVID) were retrieved to screen clinical studies of acupuncture-moxibustion treatment of AD according to the inclusion and exclusion criteria to conduct quantitative, clustering and association analyses. Results: In acupuncture-moxibustion treatment of AD, the frequently used points were Baihui (GV 20), Zusanli (ST 36), Sishencong (EX-HN 1), Taixi (KI 3), Sanyinjiao (SP 6), and Neiguan (PC 6) in the descending order. Regarding meridians, the most frequently used one was the Governor Vessel, followed by the Stomach Meridian of Foot Yangming and Gallbladder Meridian of Foot Shaoyang. From the perspective of body regions, the points in the head-face region and the lower-limb region had the highest frequencies, followed by the upper-limb, back and chest-abdomen regions. The point group, Baihui (GV 20) and Sishencong (EX-HN 1)-Neiguan (PC 6)-Sanyinjiao (SP 6), showed the most significant association, and the group winning the second place was Baihui (GV 20) and Sishencong (EX-HN 1)-Neiguan (PC 6)- Zusanli (ST 36). The clustering analysis showed that the commonly used point pairs included Zusanli (ST 36)-Sishencong (EX-HN 1) and Taixi (KI 3)-Sanyinjiao (SP 6), which were closely associated with Baihui (GV 20). By analyzing the three commonly used acupuncture-moxibustion methods, acupuncture plus medication was found achieving the best result in the total effective rate and mini-mental state examination (MMSE) score, followed by monotherapy of electroacupuncture therapy, and these two methods were superior to acupuncture alone (P<0.05); the scores of MMSE, Alzheimer disease assessment scale-cognitive section (ADAS-cog) and activity of daily living scale (ADL) showed significant improvements after treatment (all P<0.01). Conclusion: In the acupuncture-moxibustion prescriptions for AD, the main points are Baihui (GV 20), Sishencong (EX-HN 1), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taixi (KI 3). Monotherapy of acupuncture has the highest frequency amongst the treatment methods, but its effective rate is lower than that of acupuncture plus medication and monotherapy of electroacupuncture.

Objective To study the outcomes and influencing factors of the conversion from normal glucose tolerance -hyperinsulinemia (NCT-HINS) to diabetes in the population of a community in Beijing.Methods All the subjects investigated received 75 g oral glucose tolerance test (OGTT) for diabetes screening carried out in May, 2006 and May, 2008. Data were calculated to analyze the outcomes and influencing factors of the conversion. HINS was diagnosed if fasting serum insulin & 15 mIU/L and/or 2-hour serum insulin after glucose loading ≥ 80 mIU/L Results The prevalence of NGT-HINS in the community in 2006 and 2008 was 5.28% and 8.67% (P<0.01) respectively and that of diabetes mellitus (DM) and impaired glucose regulation (IGR) was 3.52% , 6.56% in 2006 and 4.42% ,6.47% in 2008.The probability of the conversion from NGT-HINS to IGR and DM was 18.6% and 2.3% , being much higher than that from normal glucose tolerance- normoinsulinemia (NGT-NINS) (5.4% and 0.7% , P <0.01). However, the probability of the conversion from NGT-HINS to DM was 2.3% , which was much lower than that from IGR (26.3% , P <0.01). The reason might be that individuals with NGT-HINS had a higher waist circumference, BMI, fasting plasma glucose, 2 h plasma glucose and TG but a lower HDL-C than individuals with NGT-NINS in 2006. The HOMA β-cell function index/HOMA insulin resistance index (HBCI/IR) of individuals with NGT-HINS was much lower than that of individuals with NGT-NINS, but much higher than that of individuals with IGR. Logistic regression analysis showed that age, TG and HBCI/IR were the major influencing factors of the conversion from NGT to glucose metabolic disorders.Conclusions The probability of conversion from NGT to DM was increased remarkably when HINS was diagnosed. The reason might be that individuals with NGT-HINS suffered more metabolic risk factors and had a decreased β-cell function. Therefore, individuals with NGT-HINS should be paid attention to in diabetes prevention study.

OBJECTIVETo observe whether Xuefu Zhuyu Decoction (XZD) could induce the differentiation of mesenchymal stem cells (MSCs) into cardiac myoid cells, thus seeking for safe and effective inducers.
METHODSThe serum pharmacological method was used to induce. XZD containing serum was prepared. MSCs were isolated and cultured. The serum cytotoxicity was detected by MTT. The third generation of favorably grown cells was selected in this experiment. Cells were divided into three groups, i.e., the vehicle control group, the XZD containing serum induced group, and the 5-azacytidine induced group. Expressions of Desmin and alpha-actin were detected by immunocytochemical staining method.
RESULTSBefore induction protein expressions of Desmin and alpha-actin were negative, and few was weakly positive. There was no statistical difference in the weak positive expression rate among the 3 groups (P > 0.05). After induction protein expressions of Desmin and alpha-actin were negative, and few was weakly positive in the vehicle control group. Protein expressions of Desmin and alpha-actin were positive in the XZC containing serum induced group and the 5-azacytidine induced group. There was statistical difference in the positive expression rate when compared with the vehicle control group (P > 0.05).
CONCLUSIONSXZD played a role in in vitro inducing differentiation MSCs to cardiac myoid cells. It might participate in expressions of Desmin and alpha-actin.
