Objective To determine whether ultrasound mediated microbubble destruction could increase naked human wild type p53 plasmid delivery to ovarian cancer in rats by intratumoral injection. Methods Forty rats with ovarian cancer successfully induced by chemical intoxicant were divided into four groups.The wild type p53 gene was cloned into a high expressing efficiency eukaryotic plasmid pcDNA 3.1+ and the mixture of naked human wild type p53 plasmid was carefully injected directly into the center of ovarian neoplasms with or without echo contrast agent, and it was exposed to ultrasound for twenty minutes once a week.Two months after p53 gene transfection, semiquantitative RT-PCR was used to detect wild type p53 mRNA expression and western blot was to evaluate p53 protein expression level. Results Recombinated eukaryotic expression plasmid DNA encoding pcDNA 3.1+ /p53 was successfully constructed and confirmed by sequence analyzing and endonuclease cutting. The ovarian cancer model of rat was obtained by exposure to intoxicant. Expression of human wild type p53 mRNA was significantly higher in rats transfected with wild type p53 plasmid by means of ultrasound and contrast agent than others(P

Objective To explore the clinical therapeutic effects of postoperative intracranial infection in neurosurgery.Methods Between January 2014 and January 2014,50 patients with postoperative intracranial infection in the department of neurosurgery in our hospital were selected in this study.Among the 50 patients,25 patients were treated by intravenous antibiotic therapy,15 patients were treated with intrathecal and intravenous antibiotics treatment,10 cases were treated by intrathecal injection,intravenous antibiotics and lumbar pool catheter drainage way for treatment,and then we observed the clinical therapeutic effect of three groups of patients.Results In 50 patients,37 patients were cured,3 cases had marked effect,8 patients had effect,2 patients had no effect.Conclusion For patients with neurosurgical operations,to maximally reduce the risk of intracranial infection,it is necessary to take antibiotics according to the actual situation of patients,and make different treatment schemes according to the difference of infection.

Referring to the rapid developed life science and the higher requirements for the approval of innovative Chinese drugs in recent years, this paper described systematically the discovery, research and development (R&D) approaches for the innovative Chinese drugs under the new situation from the following five aspects, i. e., active components discovered from TCMs, the discovery of effective fractions of TCMs and their formulae, the R&D of TCM innovative drugs based on famous classic prescriptions and famous Chinese patent drugs, and the transformation of clinical effective prescriptions, on the basis of analysing the advantages of innovative drugs derived from natural products based on TCM theories and the problems existed in current R&D of new TCM drugs. Moreover, five suggestions are also given for the rapid development of TCM innovative drugs in China. All these will provide reference for the R&D of TCM innovative drugs.

Objective To investigate the dynamic changes of glutamic acid(Glu) levels,ATP levels,free calcium ion,mitochondrial membrane potential,apoptosis related to mitochondrial pathways of apoptosis and Na+-K+-ATPase activity,and explore the mechanism of mitochondrial pathways of apoptosis in neuron injury of rats with kainite acid(KA)-induced epilepsy.Methods KA-induced epilepsy model was induced by injection of KA into the hippocampus.Forty SD rats were randomly divided into 2 groups: control group(n=8)and KA group(6 h,1 d,3 d,7 d,n=8).The concentration of Glu in hippocampus CA3 area was detected by high performance liquid chromatography.The apoptosis of hippocampus neurons and the concentration of Ca2+ were assayed by flow cytometry.The mitochondrial membrane potential was detected by JC-1.The Na+-K+-ATPase activity was examined.Results 1.The concentration of Glu in hippocampus increased at 3 d after KA injection and reached the peak after 7 d injection.2.The concentration of Ca2+ level,mitochondrial membrane potential,and the number of apoptosis neurons were significantly increased,wherase the mitochondrial membrane potential decreased after 6 h of KA injection,7 d after KA injection,and the changes were more severe.3.In the hippocampus,the activities of the Na+-K+-ATPase significantly decreased at 1 d after KA injection,and they decreased more over at 7 d after KA injection.4.The levels of ATP,mitochondrial membrane potential,and the activity of the Na+-K+-ATPase were negatively correlated with the neuron apoptosis(Pa

Abstract? AIM: To investigate changes of anterior chamber parameters after posterior chamber phakic implantable collamer lens ( ICL ) surgery and its correlation with intraocular pressure ( IOP) .?METHODS: This was a retrospective case series study. Seventy four eyes in 43 myopia patients were examined by Allegro Oculyzer anterior segment tomography to obtain the changes of anterior chamber volume ( ACV ) , anterior chamber angle ( ACA) , central anterior chamber depth ( ACD) and vault, meanwhile, to measure the IOP to analyze the correlation with anterior chamber parameters.?RESULTS: Compared with preoperative, ACV, ACA, ACD all decreased apparently ( P <0.01 ) in the postoperative period of 1, 3, and 6mo.ACV, ACA and ACD showed their stability in each period after the surgery.There were changes of vault in 1 and 6mo ( t=27.66, P=0.01).IOP had not altered when compared with the preoperative.This research revealed that IOP had no relation with ACV, ACA, ACD and vault in every phase( all P>0.05).?CONCLUSION:For patients underwent ICL, the anterior chamber parameters all decreased which included ACV, ACA, ACD, and had stabilized since early postoperative period. Correspondingly, IOP was stable and had not correlate with ACV, ACA, ACD and vault, however the long-term observation is still necessary.

Objective To evaluate the curative effect of sedation on broncholiths through bronchoscope with holmi-um laser. Methods From Jan.2008 to Dec. 2015, 12 cases with broncholiths through bronchoscope with holmium laser, male 7, female 5; the age from 35 to 64.12 cases visit a doctor when they cough, panting, haemoptysis and cough out stones. The predilection sites of bronchinal calculus: left main bronchus in 6, right middle bronchus in 4, main bronchus in 2. Thoracic computerized tomography was performed in 12 patients, which showed bronchial intra-luminal high-density shadow with distal bronchial stenosis, bronchiectasis, COPD, hilar calcifications, or mediastinal lymph node calcifications. Through bronchoscopy examination was performed in 12 cases, Broncholiths were found in 9 patients and granulomatous lesion wrapping hard lesions in 3 patients.12 cases were treated by using Dexmedeto-midine combined with Sufentanil for sedation through of bronchoscope with holmiun laser. Results All the operations were successful, the operation time 45~90 min, average 60 min . During the surgery, the patient have stable heart rate, oxygen saturation without falling, blood pressure is stable, stable hemodynamics, the patients did not complain of discomfort, without obvious heart and lung failure and other complications occurred, the operation without bleed-ing, pneumothorax, complications. All cases of postoperative respiratory system were improved after operation. The average time stay in hospital was (2.5 ± 1.4) days. Follow-up for 1~24 months (mean, 6 months) in 12 cases found no recurrence of stones and serious respiratory tract infection. Conclusions The method of Dexmedetomidine com-bined with Sufentanil for sedation on broncholiths through of bronchoscope with holmiun laser is safey, feasible and therapeutic effects were clearly, which provides a new method for the clinical on Broncholiths.
