Under the background of current strained doctor-patient relationship,the new Criminal law Amendment stipulates that people who makes medical troubles shall be persecuted for their criminal liability in order to reconstruct harmonious doctor-patient relationship.Through questionnaire survey,this paper investigated the cognitive status,cognitive channel,and improvement measures of doctor-patient relationship after the new Criminal law Amendment in college students in Nanjing,analyzed the causes,and discussed the possible path to construct harmonious doctor-patient relationship.Doctor-patient communication should be enhanced;patients should seek medicine service rationally;hospitals should effectively deal with complaints and disputes and vigorously strengthen the enforcement strength of the new Criminal law Amendment.

OBJECTIVE: To investigate the perioperative treatments of endoscopic sinus surgery for nasal diseases in patients with coronary heart disease after PCI. METHOD: Clinical data of 12 cases of endoscopie-assised surgery such as nasal tumors resection,functional sinus surgery,correction of deviated nasal septum,low-temperature plasma hemostasis in patients with coronary heart disease after PCI were analyzed retrospectively. RESULT: Serious bleeding did not take place with the 12 cases during surgery, and surgery progressed smoothly; one of patients had heavy nosebleed after surgery, however her condition was stable when received active treatment. Follow-up 3 months to 2 years, nasal diseases of 12 patients recovered well and symptoms were relieved; cardiovascular events such as hemorrhage, thrombosis and so on did not occur. CONCLUSION Due to physiological function of the heart dysfunction in patients with coronary heart disease after PCI,they often accompany a number of trouble issues such as medical disorders, oral antiplatelet drugs, surgery affordability loss and increase surgical risk. Correct and effective perioperative treatments, strictly surgical indications are really necessary which can keep patients safe through perioperative period.

BACKGROUND: Preliminary experimental study found that the human amniotic mesenchymal stem cells (hAMSCs)transplantation can improve nerve injury symptoms of rats with cerebral infarction.OBJECTIVE: To observe the survival, colonization and differentiation of hAMSCs in the infarct area of cerebralinfarction rats.METHODS: Sixty Sprague-Dawley rats were randomly assigned into hAMSCs transplantation, model or shamoperation groups (n=20/group). Animal models of middle cerebral artery occlusion were produced in the model andtransplantation groups by Zea-Longa method. One day after modeling, rats in the hAMSCs transplantation groupwere given in situ transplantation of 10 μL of hAMSCs (2×106) into the damaged striatum and cortex, while those inthe model and sham operation group were given the same volume of PBS. Within 1 week after transplantation, ratneurological defects were assessed and changes in their body mass were continuously monitored. Two weeks aftertransplantation, TTC staining was used to observe cerebral infarct size, hematoxylin-eosin staining was used forpathological observation of brain tissues, and immunofluorescent staining was used to detect expression ofneuron-specific nuclear protein.RESULTS AND CONCLUSION: With time, weight loss was increased while neurologic deficit scores were graduallyreduced in the hAMSCs and model groups. Compared with the model group, the weight loss and neurologic deficitscores were lower in the hAMSCs group,; however, there was a significant difference in the neurologic deficit scoresbut not in the weight loss between the two groups. Additionally, the hAMSCs significantly reduced infarct size,attenuated pathologic injury, and decreased the number of inflammatory cells. Immunofluorescence stainingshowed that the hAMSCs were observed at 1 week after transplantation under inverted luorescence microscope,and gradually differentiated into nerve cells at 2 weeks after transplantation. In conclusion, transplanted hAMSCsmay migrate to and survive in the cerebral infarct region, and differentiate into nerve cells in situ in rats with cerebralinfarction.

Objective To investigate the effect of irrigation with hypothermic artificial cerebral-spinal fluid (aCSF)on expression of aquaporin-4(AQP-4) in the spinal cord following spinal ischemia-reperfusion (I/R) in rabbits.Methods Fifty-four adult male New Zealand white rabbits weighing 2.0-2.5 kg were randomly divided into 3 groups (n=18 each):group sham operation(S group); group I/R and group irrigation with hypothermic aCSF (FI group). Spinal I/R was induced by clamping the abdominal aorta below renal artery for 60 min. Hypothermic aCSF(25 X.)was infused at L4,5 interspace at a rate of 30 ml/h and drained from L7,8 interspace during spinal ischemia.Neurological function was evaluated at 4, 24, 48 and 72 h of reperfusion and scored (0=no hind limb activity, 4=hind limb function completely recovered) in 6 animals in each group. Six animals were sacrificed at 4, 24 and 72 h respectively in each group.The lumbar segment (L5-8) was removed for measurement of water content and AQP-4 protein expression (by immuno-histochemistry).Results Neurological function scores were significantly lower,water content was higher and AQP-4 expression smaller in group I/R than in group S. I/R-induced effects were significantly attenuated by irrigation of hypothermic aCSF. Conclusion Irrigation with hypothermic aCSF can ameliorate the spinal cord I/R injuries by up-regulation of AQP-4 expression.

Objective To compare the effect of Buzhong Yiqi Decoction (BYD) containing different doses of Radix Astragali on fibulin-3 expression in the hemorrhoid tissues of stage Ⅲ internal hemorrhoids patients with spleen deficiency and sinking of qi, and to evaluate its therapeutic efficacy and possible mechanism. Methods Fifty-five qualified patients were randomly divided into control group(N = 15), Chinese medicine group 1(N =20), and Chinese medicine group 2(N=20). All of the 3 groups were treated with operation, and additionally, Chinese medicine group 1 was given BYD containing Radix Astragali 20 g, and Chinese medicine group 2 was given BYD containing Radix Astragali 50 g orally after operation. The scores of anal pendant expansion and anal prolapse were evaluated, and the expression level of fibulin-3 in the hemorrhoid tissues was detected by Western blot method. Results After treatment, the symptoms of anal pendant expansion and anal prolapse were improved in the 2 Chinese medicine groups (P < 0.05) , and the improvement of anal pendant expansion symptom in Chinese medicine group 2 was superior to that of Chinese medicine group 1(P<0.05). Compared with the control group, the expression level of fibulin-3 in the hemorrhoid tissues of the two Chinese medicine groups was increased (P < 0.05); the expression level of Chinese medicine group 2 showed an increasing trend as compared with that of Chinese medicine group 1, but the difference was statistically insignificant (P > 0.05). Conclusion BYD with large dose of Radix Astragali exerts stronger therapeutic efficacy for the treatment of prolapsed hemorrhoids than BYD with small dose of Radix Astragali, and its therapeutic mechanism has no obvious relation with promoting the increase of fibulin-3 expression.

Background Aniridia is a rare congenital hereditary eye disease.Studies determined that PAX6 gene mutation is closely associated with congenital aniridia,but the mutation locus are varied.Objective This study was to identify virulence mutation locus of PAX6 gene of a Chinese family pedigree with autosomal dominant aniridia.Methods A Chinese family affected with autosomal dominant aniridia was collected and examined in Affiliated First Hospital of Zhengzhou University in August 2014.Periphery blood of 10 ml was collected from all the families and 100 unrelated health controls.The genomic DNA was extracted by standardized phenol-chloroform method,and all exons and splicing junctions of PAX6 were amplified by PCR.Real-time fluorescence quantitative PCR was performed to examine the relative expression of PAX6 mRNA in patients and normal phenotype families and heahh controls.This study protocol was approved by Ethic Committee of Affiliated First Hospital of Zhengzhou University and complied with Helsinki Declaration.Written informed consent was obtained from subjects or custodian before any medical examination.Results This Chinese family inclued 3 generations and 9 members,with a classic autosomal dominant inheritance mode.Five patients were found,showing the absence of iris and cataract in 3 adult patients and only absence of the iris in 2 children,and other 4 members showed the normal phenotype.A novel heterozygous PAX6 deletion mutation c.796 del G (p.A266 fs) (GenBank ID:KP255960) in exon 10 was exclusively found in all affected individuals but not in any of the unaffected families or unrelated health controls.PAX6 mRNA level in lymphocytes was about 50％ lower in aniridia patients than in unaffected family members,indicating that this mutation caused nonsense-mediated mRNA decay.Conclusions A novel deletion mutation in PAX6 gene results in an abnormal PAX6 COOH-terminal extension in the Chinese aniridia family.This finding expands the mutation spectrum of PAX6 gene.

Congenital cataract is one of the important reasons for the blindness of children,and most congenital cataracts are genetic.At present,thirty-nine genes have been identified relating to autosomal dominant congenital cataract (ADCC).Objective This study was to identify and analyze the virulence gene of a Chinese family pedigree with ADCC by whole-exome sequencing.Methods A Chinese ADCC family was recruited in Affiliated First Hospital of Zhengzhou University from August to September in 2014.The family disease history and clinical data were recorded.The peripheral venous blood of 10 ml was collected in 14 patients with congenital cataract and 14 families with normal phenotype,and the peripheral blood samples were obtained from 100 healthy examined people as controls.The genomic DNA was extracted form all subjects using standard phenol chlorum method,and proband DNA was screened by whole-exome sequencing.Then mutation locus of the candidate gene was selected after compared with the information of database in the proband.The mutation locus of the candidate gene from 14 normal families and 100 healthy controls were amplified and sequenced by PCR technique based on the primer sequence of mutation locus of proband to verify the pathogenic gene of this ADCC family.This study protocol was approved by Ethic Committee of Affiliated First Hospital of Zhengzhou University and complied with Helsinki Declaration.Written informed consent was obtained from subjects or custodian before any medical examination.Results The family had a total of 5 generations of 68 members,in which 20 subjects were found with congenital cataract.The inheritance mode consisted with autosomal dominant inheritance.Cortical cataract was found in both eyes in the patients.Whole-exome sequencing showed that the 143rd ribonucleotide A of exon 2 explicit factor of chromosome 13 GJA3 gene mutated into G (c.143A＞G) in the proband,which resulted in the 48th amino acids changed from glutamate into glycine (p.E48G).PCR amplification product sequencing displayed that the same mutation of DNA appeared in all the patients of this family,while not the same mutation was seen in the candidate genes of normal phenotype families and 100 healthy controls.Conclusions GJA3 gene c.143A＞G is a virulence mutation site in this ADCC family,it is a supplement of the mutation spectrum of GJA3 gene.

OBJECTIVETo search the effect of PPARgamma agonists for infection of RSV in vitro.

METHODSThe CPE of Hep-2 and A549 cells induced by RSV infection were observed. The effects of 15d-PGJ2 and rosiglitazone on change of CPE of A549 cells induced by RSV infection for 48 h were observed, too. MTT assay was used to detect the rate of viral suppression, and the protective effects of 15d-PGJ2 and rosiglitazone on A549 cells induced by RSV infection for 48 h.

RESULTSA549 cells interfered by 15d-PGJ2 (5 -25 micromol/L) and rosiglitazone (10-50 micromol/L) did not show obvious CPE, MTT assay also showed that the survival rate of A549 cells induced by RSV infection with PPARgamma agonists added, was significantly higher than that of RSV infection without PPARgamma agonists added, the difference was statistically significant (P < 0.01), but comparision between the two drugs showed no statistical significance. The optimal concentrations of 15d-PGJ2 and rosiglitazone were 5 micromol/L and 10 micromol/L respectively.

CONCLUSIONSPPARgamma agonist can reduce the CPE of A549 cells after RSV infection and improve the survival rate of A549 cells. PPARgamma agonist can counteract the infection of RSV in A549 cells.

Objective To determine the expression of cathepsin D and advanced glycation end products (AGEs)in skin tissues from patients of different ages or skin tissues with different degrees of sun exposure,to evaluate their correlation,and to preliminarily investigate the role of cathepsin D in the degradation and accumulation of AGEs in photoaged skin.Methods Skin tissues were collected from sunexposed and sun-protected body sites in patients aged 15-20 years,35-40 years,55-60 years or 75-80 years.These skin tissues were divided into 8 groups according to age of patients and degrees of sun exposure,and there were 6 specimens in each group.Immunohistochemical and immunofluorescent methods were used to measure the expression of cathepsin D and AGEs in the skin tissues.Statistical analysis was carried out by factorial design analysis of variance,Wilcoxon rank sum test and Kruskal-Wallis rank sum test for analyzing associations of the expression of cathepsin D and AGEs with age and sun exposure,as well as by Pearson correlation analysis for assessing the correlation between cathepsin D expression and AGEs expression.Results Immunohistochemical study showed that the expression of cathepsin D markedly decreased along with the increase of age,but the accumulation of AGEs gradually increased along with the increase of age.In the same age group,the cathepsin D expression was lower in the sun-exposed skin tissues than in the sun-protected skin tissues,while the accumulation of AGEs was more in the sun-exposed skin tissues than in the sun-protected skin tissues.Factorial design analysis of variance showed that sun exposure could decrease the expression of cathepsin D (F =58.70,P ＜ 0.001),but increase the accumulation of AGEs (F =158.18,P ＜ 0.001).Moreover,the increase of age could lead to decreased expression of cathepsin D (F =79.49,P ＜ 0.001),and increased expression of AGEs (F =106.06,P ＜0.001).Compared with the sun-protected skin tissues,the sun-exposed skin tissues in all the age groups showed significantly lower absorbance value of cathepsin D (35-40 years:0.020 ± 0.005 vs.0.032 ± 0.005;55-60 years:0.012 ± 0.004 vs.0.026 ± 0.002;75-80 years:0.002 ± 0.001 vs.0.013 ± 0.004;all P ＜0.001),but higher absorbance value of AGEs (35-40 years:0.030 ± 0.008 vs.0.010 ± 0.003;55-60years:0.066 ± 0.010 vs.0.021 ± 0.004;75-80 years:0.085 ± 0.015 vs.0.035 ± 0.009;all P ＜ 0.001)except the age group of 15-20 years.No matter whether the skin tissues were sun-exposed or sunprotected,there were significant differences in the expression of cathepsin D and AGEs among different age groups (all P ＜ 0.001).The results of double immunofluorescence staining were similar to those of immunohistochemical study.Pearson correlation analysis showed that the expression of cathepsin D in the sun-exposed skin tissues was highly negatively correlated with the accumulation of AGEs (r =-0.915,P ＜0.05),while they were moderately negatively correlated in the sun-protected skin tissues (r =-0.730,P ＜0.05).Conclusions Along with the increase of age,the expression of cathepsin D in skin tissues decreased,but the expression of AGEs increased.In the sun-protected skin tissues,the expression of cathepsin D was moderately negatively correlated with the expression of AGEs,while they were highly negatively correlated in the sun-exposed skin tissues,suggesting that cathepsin D may play an important role in the degradation and accumulation of AGEs in photoaged skin.

Objective To investigate the impact of transplantation of human amniotic mesenchymal stem cells(hAMSCs)on the histopathological change in paraquat-induced pulmonary fibrosis in rats. Methods Forty-six female SD rats were randomly divided into the sham surgery group and the hAMSCs transplant group. Pulmonary fibrosis model was induced by 2％ of paraquat intragastric administration(100 mg/kg/rat). hAMSCs were injected through caudal vein(2 × 106 cells/mL/rat). The histopathological changes were observed through microscopy after HE and the immunohistochemical staining. Results General conditions in rats received hAMSCs transplantation were better than those of the model rats. More large area and white fibrosis nidus were observed in bilateral lung of model rats,with less dispersal spot or nidus. The construction of lung tissue was disordered in the model rats. The thickness of alveolar wall was found increased. There were large area interstitial hyperplasia and a large number of inflammatory cells infiltrations. The construction of lung tissue was apparently improved. A majority of alveolar wall was monolayer cell. There were only less and small area with interstitial hyperplasia. Inflammatory cell infiltration was significantly decreased. The anti-human nucleus specific antibody positive hAMSCs were observed planted and survived in lung interstitial tissue. And few hAMSCs were observed planted in alveolar wall. Conclusion The transplanted hAMSCs can be planted and survived in lung tissue ,and may play a therapeutic role in araquat-induced pulmonary fibrosis.
