1.Vitamin B6 related epilepsy
Chinese Journal of Applied Clinical Pediatrics 2016;31(24):1841-1848
Vitamin B6 related epilepsy is a group of epileptic diseases,seizures in which could not be con-trolled by antiepileptic drugs,but could be controlled or obviously improved by vitamin B6 .It comprises of pyridoxine dependent epilepsy and pyridoxine responsive epilepsy predominantly,and the latter includes vitamin B6 responsive in-fantile spasms,pyridox(am)ine -5′-phosphate oxidase (PNPO)deficiency,hyperphosphatasia mental retardation syndrome (Mabry syndrome)and so on.The clinical presentations of the diseases above are nonspecific,manifesting as refractory seizures onset in neonatal or infantile period,which need to be distinguished from other diseases such as new-born hypoxic ischemic encephalopathy,Ohtahara syndrome and non -ketotic hyperglycinemia.Pyridoxine dependent epilepsy,PNPO deficiency and Mabry syndrome have relative specific biomarkers and known disease -causing genes, which are helpful for diagnosis.It is suggested that pyridoxine or pyridoxal phosphate should be tried first for all patients started seizures early (including all infantile spasms patients),avoiding missing these diseases.And once diagnosed,vi-tamin B6 should be maintained long -term or all the life according to the detailed disease.

Objective To study the proctective effect of heme oxygeanse-1(HO-1) on cirrhotic rats after hepatic ischemia reperfusion injury.Methods All the rats were randomly divided into 5 groups as follows: normal group(N),liver cirrhosis group(LC),sham operation group(S), ischemia reperfusion group(I/R),and I/R+hemin group.Except for N group,the other groups were injected with 40% CCl4 twice a week.After 11 weeks,the model of liver cirrhosis was formed.The segmental(70%) hepatic ischemia reperfusion operation was carried out one week later.The animals were sacrificed 6h after reperfusion.Blood was collected to measure the liver function,antioxidative ability,NF-?B and caspase-3,and HO-1 expressions were studied by immunohistochemistry method. Results Administration of hemin to induce high HO-1 expression could lessen hepatic injury,increase MnSOD enzyme level,and decrease caspase-3 and NF-?B expresssion.Conclusion HO-1 plays an important role in protecting liver cirrhosis against ischemia reperfusion injury by increasing MnSOD enzyme level and decreasing expression of caspase-3 and NF-?B.

BACKGROUND: There is yet no evidence about whether internal carotid artery stenting with cerebral protection devices is beneficial to reducing neurological complications. OBJECTIVE: To explore the safety and efficacy of carotid angioplasty and stenting with cerebral protection devices for carotid stenosis. DESIGN, TIME AND SETTING: Non-randomized concurrent control trial was performed at Hospital Affiliated to Medical College of Chinese People’s Armed Police Force from June 2005 to January 2007. PARTICIPANTS: Seventy-four patients with carotid artery stenosis underwent stenting, including 21 with cerebral protection devices (16 males and 5 females; average age of 66.4 years, range 50-79 years), and 53 with no protection devices (36 males and 17 females; average age of 69.2 years, range 52-83 years). METHODS: Size of cerebral protection devices was confirmed according to the diameter of normal vessel at distal carotid artery stenosis. The guide wire was sent into distal stenosis under guidance of pathway picture followed by cerebral protection device release. The stent passed over the stenosis and released to appropriate site. The protection device was removed when the stenosis was relieved confirmed by routine angiography. MAIN OUTCOME MEASURES: Features of stenting process; frequency of stroke attack perioperatively and during 12-month follow-up. All of them took periprocedual anticoagulation treatment, cerebral vascular angiograpgy. RESULTS: Seventy-six self-expandable stents were delivered in 74 patients with carotid stenosis. Twenty-one cerebral protection devices were employed including 8 Angioguard and 13 Filterwire. The patients without cerebral protection devices were predilated 20 times (37.7%) with the balloons, and all were postdilated; 3 cases (5.6%) developed brief decreased heart rate and hypotension after stent release. The patients with cerebral protection devices were predilated 6 times (28.5%) with balloons, and all were postdilated; 2 cased (9.5%) developed brief decreased heart rate and hypotension after stent release and 2 (9.5%) developed angiospasm. One patient (4.7%) with cerebral protection devices had cerebral infarction (4.7%) perioperatively and another had cerebral infarction (4.7%) during the follow up. While four patients in the group without cerebral protection devices had cerebral infarction (7.5%) perioperatively, and five had cerebral infarction (9.4%) during the follow up. There were no significant differences between two groups. CONCLUSION: The results of the study show that cerebral protection devices are not helpful to reduce neurological complications in patients with carotid artery stenosis after stenting.

Intravenous thrombolysis is the only treatment that has the evidence of evidence-based medicine in acute ischemic stroke. However, the narrow time window has limited the treatment opportunities of many patients. Transcranial ultrasound thrombolysis is a very promising thrombolysis-assisted method, and transcranial ultrasound plus microbubble-assisted thrombolysis is the research hotspot in recent years. At present, more suitable ultrasonic instruments for thrombolysis and a number of ways of ultrasound-assisted thrombolysis are being developed.
9. Photochemical internalization and its application in gene delivery
Journal of Shanghai Jiaotong University(Medical Science) 2018;38(3):353-356
The translation of gene therapy from bench to bedside depends on efficient intracellular gene delivery. The macromolecular biologics such as gene combined with vectors tend to enter into the cells by means of endocytosis, where the biologics may encounter the risk of degradation in endolysosome. Recently, photochemical internalization (PCI) has emerged as a promising technique to overcome endo-lysosomal sequestration, which utilizes photosensitizer and light resulting in reactive oxygen species at sub-lethal level to destruct biofilm and facilitate intracellular drug delivery. In this article, the mechanism of PCI technology and its development for gene delivery were reviewed, which can provide the scientific basis for the possible utilization of PCI to solve the problem of endo-lysosomal escape in gene delivery.

BACKGROUND:Bipolar femoral head prosthesis has achieved the desired repair effect in patients with femoral neck fracture, but there is stil much controversy on the biomechanical properties of bipolar artificial femoral head prosthesis. OBJECTIVE:To compare biomechanical properties of the bipolar femoral head prosthesis replacement and internal fixation in the repair of femoral neck fracture in the elderly. METHODS:Twenty-three (46 sides) senile femoral neck fracture specimens were analyzed and randomized into internal fixation group(n=23)and bipolar femoral head prosthesis replacement group (n=23). Specimens in the internal fixation group underwent conventional metal implant fixation. Specimens in the bipolar femoral head prosthesis replacement group underwent bipolar femoral head prosthesis replacement. Mechanical properties of femoral prosthesis stem were tested on universal testing machine. Biomechanical properties after bipolar femoral head prosthesis replacement and internal fixation were compared. RESULTS AND CONCLUSION:(1) The maximum loadwassignificantly higher in the bipolar femoral head prosthesis replacement group than in the internal fixation group (P< 0.05). The maximum load trend images showed that the maximum load was significantly higher in the bipolar femoral head prosthesis replacement group than in the internal fixation group (P< 0.05). (2) The displacement in axial pul test was significantly shorter in the bipolar femoral head prosthesis replacement group than in theinternal fixation group (P< 0.05). The displacement trend images exhibited that the displacement in axial pul test was significantly shorter in the bipolar femoral head prosthesis replacement group than in the internal fixation group (P< 0.05). (3) These findings suggest that compared with the implant, bipolar femoral head prosthesis replacement in the repair of femoral neck fracture in the elderly is more stable, has better repair effects, can elevate hip function and obtain good initial stability.
