5.Basic fibroblast growth factors promote proliferation of endogenous neural stem cells after spinal cord injury in mice
Chinese Journal of Tissue Engineering Research 2016;20(23):3476-3483
BACKGROUND:So far steroid pulse therapy andsurgical decompressionarethe main accepted therapiesfor spinal cord injury, but these methods make no effects on injured neurons. Nerve growth factors and endogenous neural stem cels play a role in theneuronalregeneration and remyelination, which provides a newidea for spinal cord injury treatment.
OBJECTIVE:To explore the effect of the basic fibroblast growth factor on proliferation of endogenous neural stem cels after spinal cord injury and to analyze its relationship with the increased fluoro-gold labeled neurons.
METHODS:Totaly 48 Kunming mice were randomly divided into four groups including normal, spinal cord injury, treatment and sham operation groups. Acute spinal cord injury models were establishedin the spinal cord injury and treatment groups, andthe normal group was subjected to operationthat did not damage the spinal cord. At 2hoursafter regaining consciousness, the treatment group was givendailyinjection of MTPBS containing 25 μg/kg basic fibroblast growth factors and 1% album. And at 7 days, laminectomy was carried out again at the L1segment in the former three groups and a smal piece of sterile gelfoam soaked with fluoro-gold was inserted into the incision. The sham operation group was given no processing. Afterwards, mouse motor behavior was assessed using Rotarod and Platform Hang tests; neurons in the corticospinal and rubrospinal tracts were labeled with fluoro-gold; the number of endogenous neural stem cels positive for nestin was detected by immunohistochemistry method. Besides, the correlation betweenthe number offluoro-gold labeled neurons andthe number ofendogenous neural stem cels was assessed.
RESULTS AND CONCLUSION:The basic fibroblast growth factor could significantly improve the mouse motor behavior after spinal cordinjury. And the number of endogenous neural stem cels was significantly increased after the basic fibroblast growth factor injection, which was related to the increased fluoro-gold labeled neurons.In conclusion, basic fibroblast growth factors play an important role in the proliferation of endogenous neural stem cels after spinal cord injury. Furthermore, endogenous neural stem cels improve locomotive behaviors by encouraging the neuronalproliferation.
6.HFA-134a driven salbutamol sulfate metered-dose inhaler: formulation screening and respiratory tract absorption in rats
Journal of China Pharmaceutical University 2009;40(4):332-336
Aim: To study the hydrofluoroalkane-driven(HFA-134a) salbutamol sulfate (SS) MDI formulation compositions and the respiratory tract absorption in rats. Methods: Solubility determination and orthogonal design were used to aid the screening of non-CFC SS MDI formulations. Rats were exposed to SS MDI via intubation inhalation. Fluorescent HPLC detection was developed to determine plasma SS concentration in rats given the selected SS MDI formulations. Analysis of the plasma drug level-time profiles was performed by the statistical moment approach. Results: Stable and homogeneous non-CFC SS MDI formulations were obtained. The developed HPLC method was validated and used to assay SS levels in the rats after inhalation of the MDI. AUC ratios of the SS/HFA-134a-driven MDI formulation to the reference SS MDI and CFC SS MDI formulation were 109. 86% and 135. 54%, respectively. Conclusion: It is proven that the absorption of the HFA-134a SS MDI formulation in rats is equivalent to the simulant formulation commercially available oversea and better than CFC formulation.
7.Primary study of diffusion-weighted imaging in evaluation of fetal renal development
Journal of Practical Radiology 2016;32(4):580-583
Objective To investigate the characteristics of apparent diffusion coefficient (ADC)values in the normal fetal kidney and to explore the normal data reference of fetal kidney by using diffusion-weighted imaging (DWI).Methods 71 normal kidneys of fetuses confirmed by ultrasound and MR were examined with DWI with four b values of 100 s/mm2 ,200 s/mm2 ,500 s/mm2 and 700 s/mm2 ADC values of the symmetrical ROIs were compared between left and right kidney for each b value.While ADC values between different group in ipsilateral kidney were compared between different b values.And the relationship between ADC values and gestational age was also evaluated.Results When b = 100 s/mm2 ,there was a statistically significant difference between the ADC value of left and right kidney,and the remaining group showed no statistically significant differences between the ADC values of left and right kidney.Comparisons among different b values of ipsilateral kidney showed statistically significant differences among the groups with different b values except the comparison between b=100 s/mm2 and b=700 s/mm2 groups of the right kidney with the increase of gestational weeks,the ADC values of bilateral kidneys were declining,and there was a reflection of this trend in different b values. Conclusion It is feasible for using DWI to evaluate the fetal kidney development.With a selected different b value,ADC value is a specific quantitative parameter that could help evaluating normal fetal kidney development.

China Oncology 2000;0(06):-
Purpose:To evaluate the effect of preoperativ e chemotherapy or brachtherapy and radical hysterectomy on stage Ⅰb-Ⅱb locally advanced cervical cancer with high risk factors. Methods:preoperative chemotherapy or radiotherapy followed by r adical hysterectomy compared to radical hysterectomy alone in stage Ⅰb-Ⅱb cer vical cancer with higher risk factors(bulky,lower grade,small cell cancer or ade nocarcinoma). Results:①Pelvic lymphnode metastases rate was significantly decreased in the neoadjuvant chemotherapy arm compared with surgery alone(P 0.05). Conclusions:Preoperative chemotherapy followed by surgery is e ffective and superior to surgery alone in stage Ⅰb-Ⅱb cervical cancer with high risk factors.It might be able to reduce tumor volume and eliminate effectiv ely disease in lymphnodes and possibly micrometastases.It may be beneficial in improving quality of life of patients by decreasing the need for postoperative r adiotherapy. Response to chemotherapy may be a prognostic factor.Preoperative br achytherapy showed no significant advantage in eliminating lymphnodes matastases as compared to surgery alone.

Results The characteristic concentration, linear range, re-covery rate and coefficient of variation were 1.2?g/L, 0 -40?g/L, 100.16% ~102.01% and 1.82%-3.26% re-spectively. Conclusion Application of matrix modifier (NH4)2 HPO4-ascorbic acid for determination of Co with GFAAS, was easy and presented good repeatibility.
10.Efficacy of Capecitabine Combined with Cisplatin in the Treatment of Advanced Gastric Cancer and Effect on Invasion and Metastasis of Gastric Cancer
China Pharmacy 2016;27(18):2494-2496
OBJECTIVE:To observe the efficacy of capecitabine combined with cisplatin in the treatment of advanced gastric cancer and its effect on invasion and metastasis of gastric cancer. METHODS:94 patients with advanced gastric cancer were ran-domly divided into control group(47 cases)and observation group(47 cases). Control group received 65-75 mg/m2 Docetaxel injec-tion,d1,continuous intravenous infusion of 2 h+15-20 mg/m2 Cisplatin for injection,d1-5,continuous intravenous infusion of 2 h in the dark. Observation group received 1 000 mg/m2 Capecitabine tablet,orally,twice a day+Cisplatin for injection(the same us-age and dosage with control group). 3-week was regarded as a treatment course,and it lasted 3 courses. Clinical efficacy,matrix metalloproteinase-2(MMP-2)and MMP-9 levels were observed,6 and 12 months survival rate and incidence of adverse reactions were followed-up. RESULTS:There was no significant difference in the total effective rate in 2 groups(P>0.05). Grade 1-2 liver dysfunction,thrombocytopenia,and the incidence of nausea and vomiting in observation group were significantly lower than con-trol group,6 and 12 months survival rates were significantly higher than control group,the differences were statistically significant (P<0.05). Before treatment,There was no significant difference in MMP-2 and MMP-9 levels in 2 groups(P>0.05). After treat-ment,MMP-2 and MMP-9 levels in 2 groups were significantly lower than before,and observation group was lower than control group,the differences were statistically significant(P<0.05). CONCLUSIONS:The efficacy of capecitabine combined with cispla-tin is similar to docetaxel combined with cisplatin in the treatment of advanced gastric cancer,but docetaxel combined with cisplat-in is superior in terms of reducing MMP-2 and MMP-9 and safety.
