Quality Evaluation of Mori Cortex from Different Producing Areas Based on Entropy Weight-TOPSIS Method / 中国实验方剂学杂志

ObjectiveTo evaluate the quality of Mori Cortex from different producing areas by the entropy weight-technique for order preference by similarity to an ideal solution（TOPSIS）， and to provide a new evaluation method for the quality control of Mori Cortex. MethodAccording to the five key indexes of color， thickness， texture， powdery and cortex remain， a subjective scoring table was designed to evaluate the appearance of Mori Cortex. High performance liquid chromatography（HPLC） was used to determine the fingerprint and the contents of multiple components（mulberroside A， chlorogenic acid， oxyresveratrol， mulberroside C， sanggenone D， sanggenone C， morusin）， and chemometrics was used to explore the differential components of Mori Cortex from different habitats. On this basis， TOPSIS was used to comprehensively evaluate the quality of Mori Cortex from different habitats， and SPSS 22.0 software was used to carry out bivariate correlation analysis between thickness and appearance color with contents of seven components of Mori Cortex. ResultThose with lighter color， thicker root bark， tougher texture， sufficient powder and less cortex remain scored higher， and the top five were all from Anhui. The established fingerprint and determination methods were stable and reliable. Partial least squares-discriminant analysis（PLS-DA） screened three components with the variable importance in the projection（VIP） value>1（mulberroside A， sanggenone D， sanggenone C）， which made an important contribution to the difference in the origin of Mori Cortex. Correlation analysis showed that there was a significantly positive correlation between mulberroside C with lightness value（L*） and total chromaticity value（E*ab） and mulberroside A with yellow-blue value（b*）（P<0.05， P<0.01）， a significantly negative correlation between sanggenone C with b* and between morusin with L*（P<0.05， P<0.01）. And there was a significantly negative correlation between mulberroside A， chlorogenic acid， and morusin with thickness（P<0.01）， a clearly negative correlation between sanggenone D with thickness（P<0.05）， a significantly positive correlation between sanggenone C with thickness（P<0.01）. TOPSIS comprehensive scores showed that the samples from Anhui had a good score and ranked high. ConclusionThere are great differences in the quality of Mori Cortex from different habitats， and those with the close habitats show similar characteristics in appearance and component content， and lighter color and less cortex were positively correlated with the quality. Among them， the quality of Mori Cortex from Anhui is relatively good.

The value of serum CA125, HE4 and imaging examinations in detecting the recurrence of ;postoperative ovarian cancer / 中国癌症杂志

Background and purpose: Human epididymis protein 4 (HE4) has been suggested to be a novel biomarker of epithelial ovarian cancer (EOC). The present study aimed to evaluate and compare HE4 with the commonly used marker, carbohydrate antigen 125 (CA125) and imaging examinations in detecting the recurrence of postoperative EOC. Methods:In this study, 92 patients with the recurrence of postoperative EOC were analyzed retro-spectively. The treatments method included the secondary operation (48 patients) and chemotherapy (44 patients). The sensitivity of CA125, HE4 and CT/MRI examinations in detecting the recurrence of postoperative EOC were analyzed and correlated with surgical pathology and clinical follow-up results. Results:The sensitivity of CA125 and HE4 were 58.7%and 61.9%with no signiifcant difference (P>0.05). The diagnostic sensitivity of CA125 combined with HE4 (80.4%) was statistically higher than that of 2 tumor marks being applied independently (P>0.05). The diagnostic sensitivity of CT/MRI examinations (88.0%) was statistically higher than that of CA125 and HE4 (P0.05). The highest diagnostic sensitivity (97.8%) was attained by combining of CA125, HE4 and CT/MRI examinations, which was statistically high-er than that of CA125 combined with HE4 (P<0.01), and CT/MRI examinations (P<0.05). Conclusion:Serum HE4 is an effective tumor marker in detecting the recurrence of postoperative EOC as well as serum CA125. HE4 and CA125 may improve the diagnostic sensitivity statistically. The highest diagnostic sensitivity was attained by combining of CA125, HE4 and CT/MRI examinations, which is the suitable strategy in screening the patient of postoperative EOC.

Concurrent chemoradiotherapy with paclitaxel and nedaplatin followed by consolidation chemotherapy in locally advanced squamous cell carcinoma of the uterine cervix / 中国癌症杂志

Background and purpose:Cisplatin-based concurrent chemoradiotherapy(CCRT) has become the standard treatment for locally advanced cervical cancer(LACC) . But no marked survival benefi t was found for stage Ⅲ-ⅣA patients,and the high toxicity of cisplatin warrants evaluation of other chemotherapeutic agents to increase effi cacy and decrease toxicity. This study was done to evaluate the effi cacy and toxicity of paclitaxel(TXL) and nedaplatin(NDP) administered concurrently with radiotherapy followed by consolidation chemotherapy in the treatment of locally advanced squamous cell cervical carcinoma(LASCC) . Methods:29 Patients with LASCC(FIGO stage ⅡB-ⅢB) were enrolled into this study from February 5,2007 through December 10,2007. The median age was 48 years old(35-64) . Radiotherapy included external beam radiotherapy to pelvic(stageⅡB 45Gy,stage Ⅲ 50 Gy) and 192Ir brachytherapy(stageⅡB 50 Gy,stage Ⅲ 35Gy) . TXL 35 mg/m2 and NDP 20 mg/m2 were given every week for 6 weeks concurrently with radiotherapy. After one month of CCRT,TXL 135 mg/m2 and NDP 60mg/m2 were administered every 3 weeks for 4 cycles. Results:All patients completed CCRT. For the consolidation chemotherapy,25 patients received 4 cycles,2 patients 3 cycles and 2 patients 2 cycles. The clinical complete response rate was 89.7%(95%CI,78.6%-100%) ,partial response rate 10.3%(95%CI,0-21.4%) After a median follow-up of 14 months(range,8.7-18.8 months) ,the disease-free and overall survival rates were 86.2%(95% CI,73.7%-98.7%) and 96.7%(95% CI 90.2%-100%) ,respectively. One patient died due to disease progression.During CCRT,Grade 3 leukopenia occurred in 3.6%(6/169) of the cycles,Grade 3 diarrhea 0.6%(1/169) ;During consolidation chemotherapy,Grade 3 leukopenia and neutropenia occurred in 8.7%(9/104) of the cycles. There were 2 patients who developed Grade 3 late rectum toxicity. Conclusion:CCRT with paclitaxel and nedaplatin followed by consolidation chemotherapy is well tolerated and effective in patients with LASCC. A prospective randomized trial to compare this treatment strategy with standard CCRT seems to be worthwhile.

Inhibitory effect of paclitaxel combined with nedaplatin on HeLa cells transplanted in nude mice / 中国癌症杂志

Background and purpose:Paclitaxel (Taxol,TXL) combined with cisplatin (DDP) has become the common chemotherapeutic regimen for cervical cancer. However, DDP has higher toxicities. Nedaplatin (NDP), a new platinum analogue,has been shown to have a higher antitumor efficiency against cervical cancer and lower toxicity. This study was done to investigate the antitumor effect of TXL+NDP on HeLa cells transplanted tumor compared with TXL+DDP. Methods:HeLa cells were transplanted subcutaneously in nude mice. These nude mice were randomly divided into 6 groups by sorting when tumor diameter reached 5-6 mm: Control, TXL, NDP,DDP, TXL+NDP,TXL+DDP. Tumor volume and body weight were measured during experiment. The volume ratio (T/ C) was the volume of single agent treatment group and control group and used to assess the antitumor effect, and the combination ratio (CR) was used for the combined therapy. More than 20% weight loss was defined as reaching toxicity level. Results:TXL+NDP regimen had a synergistic antitumor effect (CR=0.76) on HeLa cell transplanted tumor, with a maximum weight loss 8.3%. The tumor volume of TXL+NDP was 172?60 mm3, which was significantly smaller than that of TXL(304?55 mm3) group or NDP(356?67 mm3) group(P0.05), but had a higher toxicity with 4 mice death. Conclusion: TXL+NDP regimen has a synergistic inhibitory effect on HeLa cells and lower toxicity. The efficacy of TXL+NDP regimen needs to be confirmed in clinical trials.

Effect of IFN-? on the growth of human cervical cancer transplanted subcutaneously in nude mice / 中国癌症杂志

Purpose:To study the effect of interferon-? on the growth of human cervical cancer transplanted subcutaneously in nude mice.Methods:Twenty-eight nude mice transplanted subcutaneously with human cervical cancer were divided into 4 groups: control group,positive control group(DDP group),IFN-? low dose group(1.5?10 7 u/kg) and IFN-? high dose group(3.0?10 7 u/kg). Different drugs were used from day 14 after transplantation and all mice were sacrificed after 49 days. The weight of the mice and the volume of tumor were measured. FCM was used for measuring the proportion of cell cycle S+G 2 -M(%) in tumor cells. Results:The growth inhibiting rates in DDP group,IFN-? low dose group,IFN-? high dose group were 92.8%,73.8% and 93.1% respectively. Except for mice in DDP group,there was obvious increase in the weight of mice in other three groups. As for the proportion of S+G 2 -M(%),there was no difference in control group,IFN-? low dose group and IFN-? high dose group. Conclusions:IFN-? can inhibit markedly the growth of transplanted cervical cancer,which is correlated with the IFN-? dose. The mechanism of IFN-? inhibiting cervical cancer was not due to the suppression of cancer cell proliferation.
