A rapid thin flat gel isoelectric focusing method followed by ultrasensitive silver staining was developed for the determination of apo E phenotypes. Using this method, apo E phenotypes and allele frequencies in 63 normal individuals, 70 patients with hyperlipidemia and 11 patients with familial hypereholesterolemia (FH) in Nanjing were examined. TC, TG, HDL-C, LDL-C, VLDL-C, VLDL-TG in these cases were also measured. The relative frequency of the ?4 allele is significantly lower while the relative frequency of the ?3 allele is higher in this group than in the Caucasian group. Plasma TG, VLDL-TG, VLDL-C and VLDL-C/VLDL-TG are higher in the apo E3/2 phenotype, and lower in the apo E4/3 phenotype, wherea splasma TC, LDL-C levels are lower in the apo-E3/2 and higher in the apo E4/3 phenotype. It implies that the ?2 allele has the action of increasing TG-rich lipoprotein particles and reducing ch-rich lipoproteins in plasma, while the ?4 allele has an effect opposite to that of the ?2 allele. The highest prevalence of the ?4 allele was associated with type Ⅱb hyperlipoproteinemia (HLP), while that of the ?2 allele was associated with type Ⅲ-HLP. The frequency of ?2, ?4 are higher in FH patients as compared with normal subjects.

Objective To explore the mechanism ofTiaozhong Huatan Anshen Mixture (THAM). Methods A total of 200 healthy Kunming mice were randomly and equally divided into first, second, third and fourth major groups. Each major group was further equally divided into blank group, control group and high, medium, low dose THAM groups. Each group was given an equal volume of NS, estazolam, or high, medium, or low dose THAM by gavage for 7 d. For the first major group, the changes in number of spontaneous activities after administration were evaluated. For the second major group, 60 min after administration, each group was given pentobarbital sodium (30 mg/kg body weight, minimum dose for all mice sleeping) by intraperitoneal injection, and the sleep time was recorded. For the third major group, 60 min after administration, each group was given pentobarbital sodium (15 mg/kg body weight, maximum dose for 90%-100% of all mice having righting reflex) by intraperitoneal injection. The number of mice falling asleep was recorded, and the sleep rate was calculated. For the fourth major group, mice were sacrificed after continuous administration 15 d. They were quickly removed brain tissue;homogenates were taken out in batches;5-HT and 5-HIAA levels in brain tissues were determined according to fluorescence spectrophotometric.Results Compared with the blank group, all treated groups had a reduced number of spontaneous activities, a shortened sleep latency, a prolonged sleep time, and an increased sleep rate after administration (P<0.01,P<0.05), with the most significant changes seen in the control group and high-dose THAM group (P<0.05), with out statistical significance between the two groups (P>0.05). Compared with the blank group, brain 5-HT and 5-HIAA levels in all treated groups increased in mice (P<0.01,P<0.05), with the most significant changes seen in the high-dose THAM group (P<0.05).Conclusion THAM has a significant sedative-hypnotic effect. The mechanism may be related to increasing brain 5-HT synthesis and metabolism.

AlM: To observe the clinical results of pterygium excision combined with conjunctival autograft transplantation using fibrin glue.METHODS:A total of 60 patients (60 eyes) with primary nasal pterygium were randomly divided into two groups:the fibrin glue group ( experimental group, 30 eyes) and suture group ( control group, 30 eyes ) . All patients underwent pterygium excision combined with conjunctival autograft transplantation. ln the experimental group autograft was attached to sclera with fibrin glue while in control group 10-0 polyamide was used. The patients were followed up for 6mo. The time of operation, post operation comfort, complications and recurrence were evaluated.RESULTS:The average surgical time was 24. 5 ± 6. 5min with fibrin glue group while 35. 2 ± 5. 4min with suture group, with statistically significant difference between two groups (P<0. 05). Pain and foreign body sensation was significantly less with fibrin glue group than that in the control group ( P < 0. 05 ). No severe postoperative complication occurred both in two groups. The incidence of subconjunctival hemorrhage in the experimental group was lower than that in the control group (P<0. 05). 1 case (3%) of fibrin glue group, 3 cases (10%) of suture group had recurrence at the end of follow up 6mo.CONCLUSlON:lt's a safe and effective way to attach conjunctival autograft during pterygium surgery by fibrin glue. lt can reduce surgical time, postoperative complications and relieve postoperative discomfort.

Mitogen - activated protein kinases (MAPKs), including extracellular signal - regulated kinases (ERKs), c - Jun NH2 - terminal kinases (JNKs) and p38 MAPK, play an important role in transducting environmental stimuli to the transcriptional machinery in the nucleus in mammalian cells by virtue of their ability to phosphorylate and regulate the activity of various transcription factors. It was recently found that the changes in activity of MAPKs occurred during ischemia/reperfusion, but the biological significance of the changes was still controversial.

Objective To investigate the efficacy of acupoint selection at distant places and local tenderness points in treating migraine without aura.Method Sixty patients were randomly allocated, using a random number table, to two groups, 30 cases each. The treatment group received acupuncture at distant points selected along meridians and local tenderness points and the control group, acupuncture at conventionally selected points. The therapeutic effects were evaluated using the visual analogue scale (VAS) and the short-form McGill Pain Questionnaire (SF-MPQ).Result After treatment, the VAS pain score was lower in the treatment group than in the control group; there was a statistically significant difference (P<0.05). The total efficacy rate was 93.3% in the treatment group and 73.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Both acupuncture at distant points selected along meridians and local tenderness points and acupuncture at conventionally selected points have a certain therapeutic effect on migraine, but the former produces a better effect than the later and can markedly relieve the pain and improve the quality of life in the patients. The outcome of this study provides a certain reference value for clinical treatment of this disease.

AIM: To investigate the change and the possible role of mitogen-activated protein kinase(MAPK) subfamilies in early recovery process following acute renal ischemia/reperfusion injury. METHODS: Ischemia/reperfusion renal injury model was made by placing an atraumatic vascular clamp in renal pedicel. The morphologic change was observed by transmission electron microscope. The proliferating cell nuclear antigen(PCNA) positive renal cells were detected by immunohistochemistry. Extracellular signal-regulated kinase (ERK) and c-Jun NH 2-terminal kinase(JNK) activity was assayed by specific substrate phosphorylation with immunoprecipitation. RESULTS: After acute ischemia, microvilli in renal tubular cells appeared again after 2h of reperfusion. At the same time, the PCNA-positive cells were initially increased. ERK activity decreased at 45 min of ischemia, and completely recovered at 5 min of reperfusion. JNK activity was not influenced by ischemia, but increased at 5 min of reperfusion, reaching its maximal activity at 20 min of reperfusion, and prolonged within 2h reperfusion. CONCLUSION: After renal ischemia/reperfusion injury, the early recovery of renal tubule damage was related to the changes of MAPKs in which the increase of JNK activity might be more important.
