1.Anticonvulsant effect of ceftriaxone sodium in temporal lobe epilepsy
Basic & Clinical Medicine 2017;37(5):658-662
Objective To study the effects of ceftriaxone sodium(Cef) on the seizures and the expression of glutamate transporter (GLT-1) in kainic acid (KA) epilepsy model.Methods Firstly, a chronic spontaneous seizure mouse model was established by unilateral hippocampal injection of KA and monitored by vEEG technique to record seizures.The experimental group received intraperitoneal injection of Cef 200 mg/(kg·d) and the control group received normal saline.Seizure frequency, interictal spike waves and histological phenotypes were recorded to evaluate the function of Cef.Then we use the Western blot to detect the effect of expression for GLT-1.Results Unilateral hippocampal injection of KA 200 ng successfully established the mesial temporal lobe epilepsy model.Cef can reduce the seizures from 2.145 times/day to 1.597 times/day, decreased by 31.2% with a statistical significance(P<0.05).Cef treatment did not significantly enhance the expression of GLT-1.Conclusions Intraperitoneal injection of Cef partially inhibites the seizures of KA model, but the expression of GLT-1 in hippocampus is not enhanced.It is suggested that ceftriaxone may inhibit seizures through other mechanisms.
2.Application of beta blockers in the treatment of patients with heart failure
Chinese Journal of Practical Internal Medicine 2001;0(03):-
Beta blocker can be categorized by non-selective agents,selective agents and agents with vasodilatory effect.Beta blocker therapy represents a major advance in the treatment of heart failure patients.The mechanisms include up-regulation of beta receptor,reversing remodeling,improving contractile and diastolic function,antiarrhythmia and anti-ischemia.Evidences from randomized controlled clinical trials have supported its use in the treatment of patients with heart failure to decrease mortality and improve life quality.Guidelines with various versions recommend that ?-blockers are indicated for patients with symptomatic or asymptomatic heart failure and a depressed ejection fraction of lower than 40%.There is something to be noticed for rational use of ?-blockers such as timing,dosage,duration and contraindications.
3.Research on strategy of intellectual property protection of traditional Chinese medicine from the perspective of enterprise
International Journal of Traditional Chinese Medicine 2014;(7):577-580
Traditional Chinese medicine is the few field of owing independent intellectual property in China, the implement of intellectual property strategy is important for the long-term development of traditional Chinese medicine enterprises. At present, traditional Chinese medicine enterprises still remain many problems in intellectual property protection, such as weak awareness of intellectual property protection, lack of intellectual property protection professional personnel, inadequate investment in R & D and low innovation level. These problems caused huge losses in practice to traditional Chinese medicine enterprises. After analyzing the status of intellectual property protection of traditional Chinese medicine enterprises, we put up with some concrete measures of intellectual property protection of traditional Chinese medicine considering the reality of these enterprises.

Journal of Medical Postgraduates 2003;0(04):-
Objective:Peripherally inserted central catheter(PICC) has been application in clinical for many years,but the training in the knowledge about maintenance wasn't univesal systematically yet.To analyze the existed problems on the clinical peripherally inserted central catheter in washpipe technology and find out countermeasures. Methods: The self-made questionnaire was used to survey a total of 46 nurses in every department and make on-site operation demonstration. Results: Only 12 nurses' operation was completely correct and the correct rate was 26.1percent,which was related to the training,manager's attention,nurses' participate awareness. Conclusion: The training on nurses' operation of red tube needed to be strengthen.

Objective:
To analyze the death among children under 5 years of age in Huzhou City, Zhejiang Province from 2012 and 2021, so as to provide insights into reduction of mortality among children.
Methods:
The mortality surveillance data among children under 5 years of age in Huzhou City from 2012 to 2021 were collected from Children Death Report Cards and Surveillance Report among Children under 5 Years of Age, including gender, place of residence, date of death and death diagnosis. The trends in mortality and cause of death were analyzed among children under 5 years of age in Huzhou City from 2012 to 2021.
Results:
A total of 1 262 deaths occurred among children under 5 years of age in Huzhou City from 2012 to 2021, with mean annual mortality of 4.39‰, and the mortality appeared a tendency towards a decline (χ2trend=132.695, P<0.001). A total of 899 infants died, with mean annual mortality of 3.13‰, and 363 children at ages of 1 to <5 years died, with mean annual mortality of 1.26‰. The mortality appeared a tendency towards a decline among both infants (χ2trend=117.778, P<0.001) and children at ages of 1 to <5 years (χ2trend=19.201, P<0.001). A total of 724 local children died, with mean annual mortality of 3.33‰, and there were 538 deaths among floating children, with mean annual mortality of 7.65‰. The mortality appeared a tendency towards a decline among both local (χ2trend=43.728, P<0.001) and floating children (χ2trend=94.038, P<0.001). The five most common causes of death included preterm birth or low birth weight (207 deaths, 16.40%), drowning (155 deaths, 12.28%), accidental asphyxia (138 deaths, 10.94%), other congenital abnormalities (126 deaths, 9.98%), and congenital heart diseases (113 deaths, 8.95%).
Conclusions
The mortality appeared a tendency towards a decline among children under 5 years of age in Huzhou City from 2012 to 2021, and preterm birth or low birth weight was the predominant cause of death.

Eukaryotic elongation factor 2 kinase (eEF2K) is well known as a Ca2+/calmodulin (CaM)-dependent kinase. eEF2K catalyzes the phosphorylation of eEF2 and subsequently inactivates eEF2 by impairing its ability to bind to the ribosome, thereby negatively modulates protein synthesis. The high expression of eEF2K has been found recently in several types of malignancies. As participating in the progress of tumor, eEF2K emerges a potential target for future cancer therapy. The relationship between eEF2K and tumor, and the latest progress of eEF2K inhibitors were summarized in this article.

Objective To explore the risk factors for complicated hypertension in type 2 diabetic patients. Methods A community-based case-control study was conducted and some risk factors of complicated hypertension in type 2 diabetic patients were analyzed.126 cases and 273 controls were type 2 diabetic patients with and without hypertension respectively.Results The results from univariate logistic regression analysis showed that the occurrence of complicated hypertension in type 2 diabetic patients was statistically related to the body mass index(BMI),waist hip ratio(WHR) and the intake of grain crop.The corresponding OR with 95% CI were 1.474(1.101~1.973),1.478(1.180~1.852) and 1.349(1.098~1.657),respectively.After adjusted for confounding factors,the associations mentioned above were still statistically significant.No associations were observed between complicated hypertension in type 2 diabetes and diabetes duration,glycemia control,exercise,smoking and alcohol drinking,serum total cholesterol,triglycerides,high density lipoprotein,low density lipoprotein and very low density lipoprotein cholesterol levels.Conclusion The high body mass index(BMI),high waist hip ratio(WHR) and high intake of grain crop may increase the risk for the complicated hypertension in type 2 diabetic patients.
