Journal of Clinical Surgery 2015;(4):293-296
Objective To evaluate the expression of p53 in triple negative breast cancer( TNBC) and its impact on the prognosis of TNBC systematically. Methods Documents published on PubMed, Medline,CNKI,CNKI,Wanfang data,and VIP data were screened for relative researches. Two reviewers filtered,extracted and assessed the literatures according to the inclusion criteria and exclusion criteria. The meta analysis was conducted by using RevMan5. 0 software. Result A total 13 trails were included,con-taining 11 Chinese documents and 2 English documents. The meta analysis showed that p53 is significantly expressed in TNBC[OR=2. 02,95%CI(1. 28,3. 19)]. TNBC patients with positive p53 expression had higher rates in lymph node metastasis[OR=2. 02,95%CI(1. 28,3. 19)],recurrence[OR=3. 39,95%CI(1.45,7. 90)],metastasis[OR =2. 65(1. 36,5. 18)],disease-free survival[OR =0. 29(0. 18, 0. 47)]and overall survival[OR=0. 29(0. 18,0. 47)]than patients with negative p53 expression. Con-clusion p53 is overexpressed in TNBC,which plays a certain role in guiding the clinical prognosis of TN-BC. It can be regarded as an independent factor to evaluate the prognosis of TNBC,and a therapeutic tar-get in further studies.

BACKGROUND:As a kind of dental implant material, the application of titanium has certain restrictions because of its higher probability of postoperative bleeding rate, infection and gingival hyperplasia. Studies have shown that polymethylmethacrylate has been used in artificial joints and artificial bones, but rarely reported to be used as dental implant material. OBJECTIVE:To explore the biocompatibility indexes such as cytotoxicity, cel adhesion rate, relative cel proliferation rate and post-implantation inflammatory response of human osteoblasts when pure titanium and polymethylmethacrylate are used as dental implant materials, so as to provide certain reference basis for the clinical usage of polymethylmethacrylate as the dental implant material. METHODS:Human osteoblasts were cultured in vitro. Three groups were divided as folows: control group (cels cultured normaly), pure titanium group (cels cultured with titanium extract) and polymethylmethacrylate group (cels cultured with polymethylmethacrylate extract). RESULTS AND CONCLUSION:Compared with the control group, the cel adhesion rate was significantly decreased after 2, 4, 8 and 16 hours of culture with pure titanium and polymethylmethacrylate extracts (P < 0.05); the cel adhesion rate in the polymethylmethacrylate group was higher than that in the pure titanium group (P < 0.05). Compared with the control group, the cels were sparse and grew slowly after 2 days of culture with pure titanium and polymethylmethacrylate extracts. Cels in the polymethylmethacrylate group grew faster with fusiform distribution and obvious drawing phenomenon. Compared with the control group, the relative cel proliferation rate was significantly decreased after 2 days of culture with pure titanium and polymethylmethacrylate extracts (P < 0.05); the relative cel proliferation rate of polymethylmethacrylate group was higher than that of the pure titanium group (P < 0.05). The expression of inflammatory factors in rat serum was significantly increased after 7 days of implantation of titanium and polymethylmethacrylate materials (P < 0.05), the expression of inflammatory factors in the polymethylmethacrylate group was less than that in the titanium group (P < 0.05). There was only one rat developing alergic reaction, but no pyrogen reaction and no death in the polymethylmethacrylate group; and three rats presented with alergic reaction, one rat present with pyrogen reaction and no death occurred in the pure titanium group. These results demonstrate that as the dental implant material, polymethylmethacrylate is superior to pure titanium in the cel toxicity, inflammatory response and biocompatibility.

OBJECTIVE:To provide reference for the individualized treatment of opioid drugs by investigating the effects of OPRM1 A118G gene polymorphism on opioids dosage in Chinese Han Population patients with cancer pain. METHODS:66 Chi-nese Han Population patients with medium and severe cancer pain were selected from a third grade class A hospital. Using fluores-cence in-situ hybridization,OPRM1 A118G genotypes were detected to compare the opioids dosage of different genotype in pa-tients with cancer pain. RESULTS:Among 66 patients,distribution frequency of AA,AG and GG genotype were 36.36%, 53.03% and 10.61%,respectively;those of A and G allele were 62.88% and 37.12%;the daily dosage of opioids in AA,AG, GG genotype patients respectively were(21.67±13.41),(42.00±32.18)and(87.14±73.65)mg,with statistical significance(P<0.001). Among 39 patients receiving opioids for the first time,the dosage of 6 AA genotype patients and 15 AG genotype patients had been adjusted,with statistical significance(P=0.026). After adjusting dosage,daily dosage of AA genotype and AG genotype patients were (16.11 ± 9.16) and(28.57 ± 18.52)mg,with statistical significance (P=0.011). CONCLUSIONS:OPRM1 A118G genotype can influence the dosage of opioid in Chinese Han Population patients with cancer pain,and gene polymorphism can be used as evidence for dosage guide of opioids.

This study aimed to identify Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants by ITS2 sequence. All the DNA samples of Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants were extracted. The ITS2 sequence were succesfully amplified, and purified PCR products were sequenced. All the sequences were assembled using the CondonCode Aligner V3.7.1. The Kimura 2-Parameter (K2P) genetic distances and the Neighbor-Joining (NJ) phylogenetic tree were calculated by using MEGA5.1. Results indicated that the maximum intraspecific genetic distances of Belamcandae Rhizoma was 0, and the average GC content was 52.22%;the maximum intraspecific genetic distances of Iridis tectori Rhizoma was 0.004, and the average GC content was 67.87%. The maximum K2P intraspecific genetic distance of Belamcanda chinensis, Iris tectorum were both lower than the minimum interspecific genetic distance of adulterants. Additionally, the ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. The NJ tree based on ITS2 sequence indicated that Belamcandae Rhizoma, Iridis tectori Rhizoma and their adulterants could be distinguished clearly. It could be concluded that ITS2 barcode can be used to correctly identify Belamcandae Rhizoma, Iridis tectori Rhizoma from their adulterants, and ensure their safety in use.

Objective To investigate the diagnostic value of serum proadrenomedullin( pro-ADM)in catheter related blood stream infection( CRBSI). Methods Prospective diagnostic test was performed with 76 cases patients with clinically suspected diagnosis of CRBSI,and the patients were divided into CRBSI group( n=25)and non-CRBSI group. Serum pro-ADM,procalcitonin( PCT),C-reactive protein( CRP)and white blood cell( WBC)levels were measured at the study entry and on the day of CRBSI suspicion. Results On the day of CRBSI suspicion,the levels of pro-ADM,PCT,CRP and WBC in the CRBSI group were(5. 17 ± 1. 28)nmol/L, 2. 29(1. 47-4. 28)μg/L,(102. 04 ± 51. 00)μg/L and(14. 66 ± 5. 09)× 109/L respectively,significantly higher than those in the non-CRBSI group((2. 83 ± 1. 25)nmol/L,2. 29(1. 4-4. 28)μg/L,(61. 43 ± 53. 52) mg/L and(11. 78 ± 3. 52)× 109/L respectively;t or Z=7. 636,-4. 777,3. 156,2. 882;P﹤0. 05). For the diagnosis of CRBSI,the area under the curve(AUC)of pro-ADM,PCT,CRP and WBC were 0. 89(95%CI 0. 82-0. 97),0. 84(95%CI 0. 75-0. 93),76(95%CI 0. 65-0. 86)and 0. 68(0. 54-0. 81)respectively. Taking pro-ADM with 4. 31 nmol/L as the cutoff value,the sensitivity,specificity,positive predictive value and negative predictive value were 76. 0%,84. 3%,70. 4% and 87. 8% respectively. Simultaneously,taking procalcitonin with 1. 52 μg/L as the cutoff value, the sensitivity and specificity was 81. 8% and 87. 0%respectively. Conclusion Serum level of pro-ADM in the diagnosis of CRBSI has good specificity. Simultaneous surveillance of serum pro-ADM and PCT may be helpful for the diagnosis of CRBSI in the early stage.
