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.

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.

Chinese Pharmacological Bulletin 2019;35(10):1381-1387
Aim To explore the effects of depression on tumors, as well as its molecular mechanisms. Methods The chronic unpredictable mild stress model (CUMS) was constructed. Tumor was inoculated after behavioral test, and the differences in serum norepinephrine and tumor volume between groups were detected. Breast cancer cells were stimulated by administration and invasion, migration, proliferation and cell cycle distribution were detected. Western blot and immunofluorescence were utilized to detect cell surface receptors and intracellular signaling pathways. Results Depression up-regulated the level of norepinephrine (N E) and increased the phosphorylation of p38 MAPK, resulting in increased malignancy of breast cancer cells. Conclusions Depression may increase the malignancy of breast cancer through norepinephrine-induced p38 MAPK signaling pathway, thus increasing the malignant degree of breast cancer.

Objective • To investigate the current status of self-perceived burden of the patients with non-Hodgkin's lymphoma (NHL) and analyze the related factors. Methods • A total of 169 NHL patients who were hospitalized in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from Jan. to Oct., 2019, and their caregivers were enrolled by convenience sampling method. The general information questionnaire, Social Support Rating Scale (SSRS), Self-rating Depression Scale (SDS), Zarit Caregiver Burden Interview (ZBI) and Self-perceived Burden Scale (SPBS) were used to investigate, and the factors related to the score of SPBS were analyzed. Results • The average score of SPBS was 28.95±11.27, while the score of economic burden was the highest (3.13±1.37). Multiple regression analysis suggested that the family income per month per person (P=0.001), Karnofsky performance status (KPS) (P=0.027), SDS score (P=0.006) and ZBI score (P=0.000) were associated with the SPBS score in the NHL patients. Conclusion • The overall selfperceived burden in the patients with NHL is mild-to-moderate, but the economic burden is not neglectable. Low monthly income, poor ability of self-care, depressive symptoms and heavy burden of caregivers can aggravate the self-perceived burden of the patients with NHL.

The corneal transparency is one of the important basic conditions for realizing normal physiological functions of visual organs. Also corneal endothelial cells are important conditions for maintaining normal corneal transparency. Therefore, only to ensure the morphology and physiological integrity of the corneal endothelial, can have normal vision. However, intraocular surgeries inevitably cause damage to corneal endothelial cells. This paper will review the effects of glaucoma surgery on corneal endothelial cells.
