1.TREATMENT AND PROGNOSIS OF PRIMARY EXTRANODAL LYMPHOMAS
Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(04):-
This paper presents 73 cases of primary extranodal lymphomas admitted during 1965~1975, accounting for 14.4% of 507 cases of Iymphomas in this department at the same period. The primary tumors occurring in the extranodal sites or organs were fully proved by histories and physical examinations. There were 11 sites or organs. 70 cases have been treated by various methods, 23 by irradiation alone, 47 cases by the combined therapeupics. The 3-year and 5-year survivas rates were 49.2% and 45.1% respectively The prognosis was poor in those who was younger than 20 years of age. The survival rate in stage Ⅰ and Ⅱ was higher than in stage Ⅲ and Ⅳ. The factors causing fatal outcome were the late stage, and incomplete treatment, inadquate radiation dose and inappropriate chemotherapy.

Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(04):-
A total of 154 sera from patients with nasopharyngeal carcinoma(NPC), patients with other head and neck tumors(OHNT) and healthy individuals (HI) from Shaanxi province were tested for IgA antibody to EB viral capsid antigen (VCA-IgA) by immunoenzyrnie method. 75.93% of 54 pretreated NPC patients had VCA-IgA antibody with a GMT of 1: 38. 00,whereas less than 12. 00%of 50 OHNT and 50 HI with a GMT of 1: 2. 5 ~ 1: 3. 35.The results showed that the detection of VCA-IgA was of great value in diagnosis of NPC from low risk areas. The elevated level of VCA-IgA was seen in well-differentiated squamous cell carcinoma which gave a pattern similar to that noted in vacuolar nuclear cell carcinoma or less-differentiated carcinoma, but not in undifferentiated carcinoma. The VCA-IgA positive ratio in NPC patients below 30-year-old was similar to that in OHNT, however the GMT was elevated markedly. The results above showed that VCA-IgA antibody was of little value in diagnosis of NPC below 30-year-old and undifferentiated carcinoma.
3.Advances in the genetics of spinal muscular atrophy in childhood
International Journal of Pediatrics 2010;37(5):540-541
Spinal muscular atrophy in childhood is one of the most common neuromuscular disorders with an autosomal recessive mode of inheritance. The main pathogenesis is homozygous loss and small intragenic mutations of the SMN1. SMN2 ,as a very identical copy of SMN1, modulates the disease severity. The functional difference between both genes is a variance of single nucleotide within the coding region, causing silent mutation obviously to decrease SMN2 transcripts. Histone deacetylase inhibitors have been shown better perspective in clinical trials.

Objective To investigate the role of mitochondrial KATP (mito-KATP) channel in reduction of renal ischemia-repeerfusion (I/R) injury by ischemic postconditioning (IPo) in rats. Methods Thirty-five adult male SD rats weighing 250-280 g were randomly divided into 5 groups ( n = 7 each): group Ⅰ sham operation (group S); group Ⅱ I/R; group Ⅲ IPo; group Ⅳ 5-HD + I/R and group V 5-HD + IPo. The rats were anesthetized with intraperitoneal (IP) chloral hydrate 300 mg/kg. Bilateral kidneys were exposed and their pedicles were occluded for 45 min with atraumatic mini-clamp followed by 6 h reperfusion in group Ⅱ - Ⅴ . In group Ⅲ and Ⅴ 3 cycles of 10 s reperfusion followed by 10 s ischemia were applied immediately after 45 min kidney ischemia. In group Ⅳ and Ⅴ 5-HD (a specific blocker of the mito-KATP channel) 10 mg/kg was given IP at 30 min before ischemia. Blood samples were obtained at 6 h of reperfusion for determination of serum creatinine (Cr) and urea nitrogen (BUN) concentrations. The animals were then killed. Bilateral kidneys were removed for determination of mitochondrial membrane potential in the renal tubular epidural cell and intracellular reactive oxygen species (ROS)content and free Ca2+ concentrations. Results Renal I/R significantly increased serum Cr and BUN concentrations and intracellular free Ca2+ concentration and ROC content and decreased mitochondrial membrane potential as compared with sham operation group. IPo significantly attenuated the I/R-induced changes mentioned above. The protective effects of IPo against renal I/R injury was reversed by 5-HD. Conclusion Mito-KATP channel is involved in reduction of I/R-induced renal injury by ischemic postconditioning.
