Objective:To discuss the significance of standardized treatment for cancer pain, according to the Cancer Pain Treat-ment Specification (2011 Edition) issued by the Ministry of Health, PR China. Methods:Clinical data of 126 patients with cancer pain, who were admitted to the Department of Medical Oncology, The Fourth Hospital of Hebei Medical University, were collected to com-pare the improvement of the Numeric Rating Scale (NRS) score, number of breakthrough pain, and quality of life score after treatment. The relationships between different pain grades, disease entities, and treatment effect were analyzed. The influence factors of pain relief were also analyzed by using Logistic regression analysis. Results:1). Following standardized treatment, the improvement rate of NRS score has shown significant differences in pain grading (P=0.001) and gender (P=0.000). However, no significant differences were ob-served between different diseases (P=0.112). The improvement rate of the life quality score and the number of breakthrough pain had no significant difference after standardized treatment. 2). The grading of cancer pain and the disease entities had little effect on cancer pain relief. 3). The anti-tumor treatment and“no distant metastasis”were the independent factors that brought about the decrease in NRS and quality of life scores.“No distant metastasis”(P=0.046) was the independent factor that reduced the number of pain out-breaks. Conclusion: The standardized treatment positively affects the NRS score, number of breakthrough pain, and quality of life score. Patients who received anti-neoplastic therapy and who had no distant metastasis showed significant treatment effectiveness in pain management.

The JC virus is a widely infected human polyomavirus. Recent foreign researches showed that the JC virus infection is correlated with tumors of nervous system and digestive system, while, and study on the relationship between JC virus infection and gynecological tumor is seldom reported. In this study, we first establish the nucleic acid detection methods and procedures for JC virus and its highly homologous BK virus. The JC and BK viruses infection was evaluated by detect the viral DNA in samples including biopsy tissues, serum as well as urine of myoma of uterus (98 cases), cervical cancer (84 cases), endometrial cancer (40 cases) and ovarian tumor (72 cases) patients. The BK viral DNA positive rate was significantly higher in urine samples than that of blood and biopsy samples, and there is no significant difference of the BK viral DNA positive rate among all patient groups. The JC viral DNA positive rate is almost 0 in serum samples and biopsy. tissues, however, viral DNA positive rate is more than 50% in urine samples. In fibroids group, the JC viral DNA positive rate is up to 65. 3% which is significantly higher than that in other patients groups and healthy control. Further gynecological tumor associated viruses detection showed that only human papilloma virus infection is associated with cervical cancer, the herpes simplex virus, EB virus and cytomegalovirus infection is extremely low in our patient groups. No synergistic effect on gynecological tumor caused by viruses co-infection was observed. Our study showed that JC virus infection is highly related to the pathogenesis of uterine fibroids.

The incidence of systemic fungal infections have increased dramatically, moreover, drug resistance including either primary (intrinsic) or secondary (acquired) resistance, becomes one of the main reasons accounting for the failure of treating invasive fungal infections in the past decades. Nowadays, clinically available antifungal drugs are limited and their combination in antifungal therapy was not effective. It is expected to be a new strategy to synergistically sensitize antifungal drugs against drug-resistant fungi by using new small molecules. Based on the study in our research group and the reported work of others, we reviewed the research of the natural products which have synergistic effect with the antifungal agents against drug-resistant fungi. This review focused on the resource, structure, pharmacological activity, and action mechanism of the compounds, as well as somewhat in common, and would provide theoretical base for seeking new drug against drug-resistance fungi.

Molecular systematic techniques were applied to reveal the genetic diversity of medicinal plants and their related species in Salvia. The internal transcribed spacer (ITS) as well as 5.8S rDNA sequences of 27 samples of Salvia were amplified using PCR method and sequenced. Mega 3.1 was used to analyze the genetic diversity within genus. The complete sequences of ITS plus 5.8S rDNA are about 612-617 bp. A phylogenetic tree generated by Neighbor-Joining method partly supported the morphological classification within Salvia, but incompatible results were also obtained in the treatment of phylogenetic positions of some species such as Salvia trijuga, Salvia flava var. flava and Salvia flava var. megalentha. The ITS regions of present Salria species showed considerable variation between subgenera in contrast with the conservative 5.8S rDNA sequences. The native Salvia species might have a different origin from the foreign species. The phylogenetic positions of subgenera and sections inferred by ITS analysis were comparable with that of traditional classification, while the phylogeny within sections is still doubtful due to limited information in ITS sequence and need to be further proved by other evidence. ITS analysis in this study supports the rationality of using species from Drymosphace section as substitute drug resources of Dan shen, but also reveals significant genetic differences between high mountain Dan shen species such as Salvia przewalskii with traditional Dan shen origins.

Objective To investigate the role of dynophin and substance P in pruritus with 5/6 subtotal nephrectomy rats (STNx). Methods 5/6 subtotal nephrectomy rots were prepared. After 24 weeks , STNx rats entered in end stage renal disease(ESRD). Sixty male SD rats were divided into 4 groups, STNx+P group(n=15), STNx+dynophin group( n=15), STNx control group(n=15) and sham operation group(n=15). Substance P (SP), dynophin and saline were intradermal injected separately. After injection, scratch reaction of rats in 30 minutes were recorded. And then SP concentration in blood was estimated by ELISA and SP expression in skin was examined by immunohistochemisty. Results SP concentration in blood of STNx rats were (1010.2±103.5)pg/ml, which increased to (2530.0± 236.3) pg/ml in STNx+SP group and decreased to (612.4±72.2)pg/ml in STNx+dynophin group, and it was the lowest in sham opera- tion group (240.2±36.5)pg/ml. SP expression in skin was similar to that of in blood. The scratch times in STNx+SP group were highest (7.3±1.9 times), there was no significant difference between STNx + dynophin group and STNx control group. Conclusion Pruritus in ESRD rats was correlated to the increase of SP in blood and skin. Intradermal injection of dynophin can decrease SP in blood and skin, but can not induce scratch in STNx rats.

Objective To discuss the impact of repeated contrast media exposure on renal function in patients who received coronary angiography ( CAG) or percutaneous coronary intervention ( PCI) within 1 week after CTA of coronary ateries. Methods A total of 258 patients who received CAG or PCI after coronary CTA were divided into the study group ( n=132, patients had CAG/PCI within 1 week after CTA) and the control group ( n=126, patients had CAG/PCI 1-2 weeks after CTA). Serum creatinine, cystatin C and estimated GFR were tested before and on day 1, 2 and 3 after procedures. The occurance of contrast-induced nephropathy ( CIN ) was recorded. Resu1ts The baseline clinical characteristics of the patients between the two groups had no significant difference. Preoperative and postoperative serum creatinine, cystatin C and eGFR values on day 1, 2 and 3 had no significant difference between the two groups (all P﹥0. 05). There was no significant difference in the incidence of CIN between two groups (5. 3% in the study group vs. 4. 8% in the control group, P﹥0. 05 ) . Conc1usions It is safe and feasible for patients with eGFR≥60 ml/( min?1. 73 m2 ) to undergo CAG or PCI within 1 week after coronary CTA.
