ABSTRACT

OBJECTIVE:To establish the fingerprint of Papaveris Pericarpium, and to determine the contents of 5 components,such as morphine ,codeine,thebaine,papaverine and narcotine. METHODS :HPLC method was adopted. The determination was performed on a Agilent ZORBAX Eclipse XDB-C18 column with mobile phase consisted methanol -sodium heptanesulfonate with gradient elution at the flow rate of 1.0 mL/min. The detection wavelength were set at 238 nm(papaverine) and 216 nm(morphine,codeine,narcotine,thebaine). The column temperature was 20 ℃,and sample size was 10 µL. HPLC fingerprints of 15 batches of Papaveris Pericarpium were established by using the Similarity Evaluation System of TCM Chromatographic Fingerprints (2012 edition),and the common peaks were determined in combination with the spectra of mixed control. The contents of morphine ,codeine,thebaine,papaverine and narcotine were determined simultaneously by the same method. The cluster analysis was conducted by using SPSS 19.0 software. RESULTS :There were 13 common peaks in 15 batches of Papaveris Pericarpium ,and the similarity was greater than 0.99. Five chromatographic peaks were identified ,which were morphine,codeine,thebaine,papaverine and narcotin. The results of cluster analysis showed that 15 batches of Papaveris Pericarpium could be clustered into two categories ,S1-S7 and S 8-S15,belonging to two cities. The linear ranges of five components were 10.21-102.10,10.43-104.30,1.54-30.70,2.36-47.28,2.32-57.90 μg/mL,respectively(all r>0.998). RSDs of precision,stability(24 h)and repeatability tests were all less than 2%. The average recoveries were 99.46%(RSD=1.08%,n= 6),97.84%(RSD=1.55%,n=6),91.10%(RSD=1.74%,n=6),96.43%(RSD=1.25%,n=6)、94.82%(RSD=1.20%,n=6), respectively. The contents of 5 components were 2.342 9-4.082 2,0.430 4-0.889 7,0.055 2-0.090 4,0.299 3-0.558 8,0.343 2- 0.656 2 mg/g. CONCLUSIONS :The established HPLC fingerprint and content determination method is simple ,feasible,sensitive and accurate. It combined with the cluster analysis could reflect characteristics and int ernal quality of chemical components in Papaveris Pericarpium .

ABSTRACT

Objective:To investigate the effects of exogenous nitric oxide (NO) on radiation response of nasopharyngeal carcinoma 5-8F radiotherapy resistant cell line (5-8FRs) and to provide experimental basis for finding suitable radiosensitizer on nasopharyngeal carcinoma.Methods:5-8FRs cells were cultured in vivo and treated with sodium nitroprusside (SNP) of different concentrations. The inhibition rate of cell proliferation was detected by cell counting kit-8 (CCK8) method. A concentration of IC 01 SNP (1% SNP) which had no obvious effect on the proliferation of 5-8FRs cells was screened out. The 5-8FRs cells were intervened with 1, 2, 4, 6 Gy and 8 Gy radiation to determine the radiation dose of IC 15 (15% radiation dose). 5-8FRs cells were treated with IC 01 SNP concentration, IC 15 radiation dose and radiotherapy alone or in combination. The morphological changes of 5-8FRs cells were observed under microscope. The proliferation inhibition rate of each group was detected by CCK-8 method, the apoptosis was detected by flow cytometry, and the concentration of NO in cell supernatant was detected by nitrate reduction method. Results:⑴ The proliferation of 5-8FRs had been inhibited in a concentration-dependent manner by SNP and a dose-dependent manner by radiation. The SNP concentration of IC 01 was (513.89±14.69)μmol/L (SNP group). The radiation dose of IC 15 was (3.96±0.33)Gy (radiotherapy group); ⑵ Compared with single SNP group and radiotherapy group, the morphology of 5-8FRs cells in combination group (SNP+ radiotherapy) was significantly different, floating cells increased significantly, the number of adherent cells gradually decreased and lost their original morphology; ⑶ SNP concentration of IC 01 had no significant effect on the proliferation of 5-8FRs cells, but the inhibition rate of combined group was significantly higher than that of radiotherapy group ( t=7.708, P<0.01); The concentration of NO in the combined group was significantly higher than that in the single radiotherapy group [(310.03±5.76)μmol/L vs (77.34±2.60)μmol/L, P<0.05]; ⑷ The spontaneous apoptosis rate of 5-8FRs was (1.35±0.06)%, while the apoptosis rate in the group of IC 01SNP was (2.22±0.37)%, with no significant difference. The apoptosis rate of 5-8FRs in the combined group (50.27±2.24)% was significantly higher than that of the group of IC 15 radiation dose(15.37±0.65)%. Conclusions:Under no obvious toxicity to cells themselves circumstances, exogenous nitric oxide with appropriate concentration could significantly enhance the radiosensitivity on 5-8FRs.

ABSTRACT

BACKGROUND:Tumor stem cels are the root of cancer recurrence and metastasis, so clinical researches should focus on the effects of different treatments on tumor stem cels. OBJECTIVE:To explore the effects of endocrine therapy and chemotherapy on stem cels in patients with breast cancer. METHODS:After recovery and cultivation of estrogen receptor-positive human breast cancer cel lines MCF-7, passage 3 cels in logarithmic phase were selected and divided into three groups containing control, estradiol and estradiol with tamoxifen groups. The estradiol group was divided into three subgroups: 10-7, 10-8 and 10-9 mol/L estradiol was added into the medium, respectively; the estradiol with tamoxifen group was divided into three subgroups: 10-7, 10-8 and 10-9 mol/L estradiol with 10-6 mol/L tamoxifen were added into the medium, respectively. The same amount of absolute ethyl ethanol was added into the medium of control group. Fifteen female patients with late recurrence and metastasis of breast cancer received chemotherapy as recurrence and metastasis group. Another 15 healthy volunteers were selected as healthy control group. RESULTS AND CONCLUSION:The proportion of CD44+CD24-/lowcel subsets in the estradiol and estradiol with tamoxifen groups was significantly higher than that of the control group (P < 0.05), and the proportion of CD44+CD24-/low cel subsets in the estradiol group was significantly higher than that of the estradiol with tamoxifen group at the same concentration (P< 0.05). The proportion of CD44+CD24-/lowcel subsets had no significant differences among groups at 10 and 20 days of culture (P < 0.05). The proportion of CD44+CD24-/low cel subsets significantly increased in MCF-7 cels after 24-hour intervention with different chemotherapy drugs. But only the proportion of CD44+CD24-/low cel subsets in the paclitaxel and doxorubicin groups was significantly higher than that of the control group after 20-day intervention (P < 0.05). Besides, the proportion of CD44+CD24-/low cel subsets in the peripheral blood of healthy volunteers was significantly lower than that of the recurrence and metastasis group (P < 0.05). Among 15 patients with late recurrence and metastatic of breast cancer, 9 had stable disease, 5 had partial remission, 1 had failed chemotherapy and cancer progression. Moreover, the proportion of CD45-CD44+CD24-/low cel subsets in the peripheral blood of patients sensitive for chemotherapy was significantly lower than that before treatment (P < 0.05). In conclusion, both endocrine therapy and chemotherapy exert a certain effect on the CD44+CD24-/low cel subsets of breast cancer positive for estrogen receptor. Given that CD44+CD24-/low cel subsets in MCF-7 cels resist chemotherapy drugs, the proportion of CD45-CD44+CD24-/low cels in the peripheral blood of patients sensitive for chemotherapy is decreased.

ABSTRACT

Objective To observe the effect of kinesiotherapy-combined scalp acupuncture plus rehabilitation on the joint range of motion (ROM) and activities of daily life (ADL) in kids with spastic cerebral palsy. Method Fifty-one eligible patients with spastic cerebral palsy were divided into a treatment group of 23 cases and a control group of 28 cases by the random number table. The control group received conventional rehabilitation, whereas the treatment group received kinesiotherapy-combined scalp acupuncture in addition to the rehabilitation therapy. Before and after treatment, a joint protractor was used to measure the passive ROM of ankle, knee, and hip joints; the Modified Ashworth Scale was used to evaluate the muscular tension of the adductor muscles of lower limbs, hamstring muscles, and gastrocnemius; the scale for ADL was adopted to evaluate the ADL. Result The joint ROM was significantly improved by different degrees in the treatment group after intervention (P<0.05), and the popliteal angle and dorsal flexion of foot in the treatment group were significantly different from that in the control group (P<0.05). In the treatment group, the muscular tension of hamstring muscles and gastrocnemius after treatment was significantly different from that before treatment (P<0.05); the change of the muscular tension of gastrocnemius in the treatment group after intervention was significantly different from that in the control group (P<0.05); the change of ADL in the treatment group after intervention was significantly different from that in the control group (P<0.05). Conclusion Kinesiotherapy-combined scalp acupuncture plus conventional rehabilitation can markedly improve the ROM and ADL in patients with spastic cerebral palsy.

ABSTRACT

A 61 year-old male patient, plasma fibrinogen level was 2.98 g/L, endoscopic sinus surgery was performed under general anesthesia for polypoid of uncinate process with mycotic maxillary sinusitis. Hemocoagulase were given in pre- and post-operative for treatment. The patient was found postoperative drain blood continuously since 3 days after surgery, when the dose of hemocoagulase reach 26 KU, and fibrinogen determined in Plasma was 0.48 g/L. Coagulation returned to normal and nasal bleeding stopped after discontinuation of the hemocoagulase and supplement with fibrinogen.

ABSTRACT

OBJECTIVE:To provide reference for performing quality control and protecting the subjects’rights and interests. METHODS:233 severe adverse events (SAE) cases reported by our hospital during Jan. 2012-Jun. 2015 were collected and ana-lyzed statistically in respects of subjects’gender and age,department,drug/equipment types,SAE types,relationship of SAE with drug/equipment,comorbidities,etc. RESULTS:The incidence of SAE in male was higher than female(71.2% vs. 28.8%);SAE mainly occurred in people over the age of 50(189 cases,81.1%);the incidence of SAE in cardiology department was the highest (137 cases,58.8%);main SAE type was hospitalization(183 cases,78.5%);most of SAE had nothing to do with studied drugs (164 cases,70.4%);more than half of the subjects suffered from other comorbidities(128 cases,54.9%). CONCLUSIONS:In order to ensure the quality of drug clinical trial data and safety of subjects,the investigator should strengthen the management of the elderly subjects and those suffering from comorbidities,to ensure that each SAE case is timely processed and accurately record-ed and reported.
