Objective To investigate the effects of astragalus membranaceus and angelica sinensis on grafted cochlea stem cells apoptosis in hearing imparied rats.Methods The hearing impaired rats were divided into 3 groups:cochlea stem cells group(45 rats),astragalus membranaceus and angelica sinensis group(45 rats),and the control group(35 rats).Cochlea stem cells only were grafted into the first group cochlea regions,mixture of stem cells and astragalus membranaceus and angelica sinensis were grafted into that of the second group.Saline was grafted into that of control rats.Observed was apoptosis at 1 day,3 days,5 days,10 days,15 days after the transplantation by CASPASE-3 and Bcl-2 immunofluorescence.Results After transplantationn 1 day,3 days,5 days,10 days,and 15 days of five time,for the cochlea stem cell group,the rates of apoptotic cells were 27.84%,49.37%,44.78%,39.37%,and 34.82%,respectively.The rates of astragalus membranaceus and angelica sinensis group were 18.35%,26.92%,23.18%,21.38%,and 18.19%,respectively.The percent of grafted cochlea stem cells apoptosis in astragalus membranaceus and angelica sinensis group was much lower than that in cochlea stem cells group and control group.The majority of apoptotic cells occurred within three to five days after transplantation.Conclusion The majority of apoptotic cells occur within three to five days after transplantation in the hearing impaired rats.The astragalus membranaceus and angelica sinensis could reduce the apoptotic rates of transplanted stem cells.

Objective To observe the effect sling exercise therapy (SET) and Tuina on radicular cervical spondylosis. Methods From August, 2015 to December, 2016, 72 patients with radicular cervical spondylosis were randomly divided into control group (n = 36) and trial group (n = 36), who accepted traction and SET+Tuina, respectively, for four weeks. They were measured F-wave conduction velocity with electromyogram from median nerve and ulnar nerve, somatosensory evoked potential (SEP), and current perception threshold (CPT) before and after treatment. The clinical ratio of improvement was calculated. Results The ratio of improvement was 83.33% in the trial group more than 58.33% in the control group (Z = 2.093, P < 0.05). F-wave conduction velocity increased in both groups after treatment (t > 12.059, P < 0.001), and increased more in the trial group than in the control group (t > 3.266, P < 0.01); while the latency of SEP decreased in N9 and N13 in both groups (t > 7.061, P < 0.001), and decreased more in the trial group than in the control group (t > 8.033, P < 0.001); the grade of CPT decreased in both groups (t > 8.895, P < 0.001), and decreased more in the trial group than in the control group (t = 8.913, P < 0.001). Conclusion The combination of SET and Tuina can promote the repair of nerve conduction of cervical spondylotic radiculopathy.

Objective To observe the effects of total saponins of tribulus of various consistency on the differentiation of neural hippocampus stem cells. Methods The hippocampus stem cells from newborn rat were obtained by serum-free medium and single-cell cloning technique. Hippocampus stem cells were induced by total saponins of tribulus of various consistency. Nestin, BrdU, neurofilament (NF-200), glial fibrillary acidic protein (GFAP) expression were detected using immunocytochemical stains. The numbers of NF and GFAP positive cells were counted. The percentages of positive cells were obtained. Results The dissociated cells from the organ of hippocampus developed into much of indiffrentiated otopheres of nestin positive cells. The hippocampus stem cell differentiated into neurons and astrocytes with the total saponins of tribulus. The percentage of NF positive neuron in the 20 mg/kg consistency of total saponins of tribulus groups was significantly higher than that in the control group and other consistency of total saponins of tribulus groups. Conclusion Total saponins of tribulus may enhance neural hippocampus stem cells differentiate into NF positive neuron.

Objective To compare the difference of entrance dose between CR and amorphous silocon DR system in chest imaging, and to discuss their optimum exposure dose. Methods For CR and DR, different entrance dose was measured by dosimeter in chest phantom. The value of IQFinv was analyzed by CDRAD2. 0 software. Image quality difference between CR and DR was assessed by group t-test. The relationship between image quality and entrance dose was tested by using Pearson correlation analysis. The best IQFinv values in CR and DR system were achieved via ROC curve analysis, and the exposure dose was then calculated. Results There were direct correlation values between entrance dose and the value of IQFinv in CR and DR system, respectively( r =0. 893 ,0. 848 ,P < 0. 01 ) . The linear regression equation for DR was IQFinv =0. 0050 +3. 359, and for CR was IQFinv =0. 005D + I. 651 , where D was entrance dose. The difference of IQFinv value between CR and DR was significant(t = 5. 455 ,P < 0. 05). The best IQFinv value of the two groups from ROC analysis was 3.55. Conclusions With the entrance dose increased, the detection ability of contrast-detail was elevated in the two digital radiography systems. With equal entrance dose, the detection ability of DR in contrast-detail was superior to CR. With equal image quality, DR obviously decreased the radiation dose to the patients.

Objective To explore the mechanism of tripterygium wilfordii hook f(TWHF)for Henoch-Schonlein purpura nephritis(HSPN,nephrotic type)in children.Methods All the children with HSPN(nephrotic type)were divided into 3 groups casually.Method of radioactive pairs conjugating analysis was used to determine the numbers of glucocorticoid(GC)receptors(GCRs).Results were statistically analysed respectively.Results GCRs tested in all the patients with HSPN(nephrotic type)before treatment were statistically lower than those in control group of normal children;GCRs in all the patients tested after 1 week treatment with GC were lower than before treatment.Three weeks later,GCRs in patients treated with TWHF increased much higher than them without TWHF.Following up the recurring times of all the patients 3 months to 5 years,they were much more in patients treated without TWHF treatment than in patients treated with it.Conclusions TWHF treatment on HSPN(nephrotic type)is obviously effective.It can not only decrease the dosage of GC,but decrease the recurring times.One of the mechanism may be TWHF can resist the down-regulation GC to GCR,and enhance the effect of GC.

0.05).Genotype CT frequency in T2DM group was significantly increased when compared with non-DM control group(P=0.012,OR=2.254).Conclusion Pro198Leu polymorphism of GPX-1 gene increases the risk of type 2 diabetes in Han Chinese of Shanghai,while T allele is not a risk factor of diabetic CHD.

0.05).Frequencies of P12A12 genotype and A12 allele in DN group were significantly decreased respectively,when compared with DN-0 group(for P12A12 genotype,9.1% vs 18.1%,P=0.034,OR=0.453;for A12 allele,4.5% vs 9.0%,P=0.041,OR=0.479). Conclusion The observations suggest that P12A polymorphism of PPAR?2 gene is associated with Chinese type 2 diabetic nephropathy,and A12 allele may protect the development of diabetic nephropathy in type 2 diabetic patients of Chinese.

Objective To explore the relationship between Arg913Gln(G→A) polymorphism of solute carrier family 12 member 3 (SLC12A3) gene and diabetic nephropathy (DN) in type 2 diabetes mellitus (T2DM) in Han population of Shanghai. Methods Two hundred and fifty-eight Han ethnic people in Shanghai with T2DM (T2DM group) were divided into non-DN group (DN0 group, n=95) and DN group (n=163) according to 24 h urine albumin excretion rate (AER), and those in DN group were subdivided into microalbuminuria group (DN1 group, n=95) and macroalbuminuria group (DN2 group, n=68). Besides, 82 people with normal results of oral glucose tolerance test (OGTT), without diabetes mellitus and nephropathy were served as controls. PCR-sequencing was used to detect the genotypes of Arg913Gln polymorphism of SLC12A3 gene. Genotypic and allelic frequencies and clinical characteristics were compared among groups. Results Three genotypes (GG, GA and AA) were detected. The frequencies of GA+AA genotype and A allele in T2DM group were higher than those in control group, while there was no significant difference between groups (P>0.05). There was no significant difference in genotypic or allelic frequencies among subgroups of T2DM group (P>0.05). The level of triglyeeride (TG), AER, level of fasting insulin (FINS) and HOMA-IR in patients with GA+AA genotype were significantly higher than those in patients with GG genotype in T2DM group (P<0.05). Conclusion Arg913Gln(G→A) polymorphism of SLC12A3 gene is not significantly associated with T2DM and DN in Han population of Shanghai. The AER of people with GA+AA genotype is significantly higher than that with GG genotype. Arg913Gln (G→A) polymorphism of SLC12A3 gene may predict the risk of increase of albuminuria in patients with T2DM in Han population of Shanghai.
