To assess early treatment for fracture of the maxillofacial bone complicated by cerebral injury, 120 patients were retrospectively reviewed. The change in GCS, the incidence of stress ulceration, nosocomial pneumonia and the injury of liver or kidney were determined 1 week after fixation of the fracture of the maxillofacial bone at different stages. There was no significant influence of the time of the operation on the severity of brain injury and the incidence of the complications. It is our assertion that the bone fracture could be fixed at an earlier stage, and RIMF is a kind of satisfactory fixation method.

AIMTo develop a rat model of insulin resistanc e,and to study the effect of puerarin injection on expression of protein kinase B in insulin resistanc e rats. METHODS30 SD rats were randomly divded into two groups. The model group were given the high fat diets(0 30 pig fat, 0 10 sucrose, 0 0 3 cholesterol) for 8 weeks. Then 9 rats of the group had been choosen as the pu erarin treatment group and were given abdominal injection (100 mg?kg -1 ?d -1 ) for 4 weeks. By the end of the experiment, Western blot and computer i mage pattern analyze system were used to analysis expression of PKB in skeletal muscles. RESULTS(1) The model group showed a hyperglycemia, hype rinsulinism and obviously visceral obesity by high fat-feeding, the insulin res istance index (ISI) decreased while the HOMA insulin resistance index (HOMA-IR) increased compared to the normal group, insulin resistance was induced in this way; (2) Compared with the pathology control group:fasting blood glucose (FBG), fasting insulin (FINS), visceral fat mass and the HOMA insulin resistance index (HOMA-IR) of the treating group were significantly decreased whereas the insuli n index (ISI) enhanced. Expression of PKB was markedly increased by puerarin tre atment. CONCLUSIONPuerarin injection can significantly elevate e xepression of PKB and ameliorate the state of insulin resistance. Improved biolo gic effect of insulin and prevention of the deleterious effect of fat may be in volved in the mechanism concerned.

Objective To study the effect of bcl-2 antisense oligodexynucleotides on the apoptosis in human small-cell lung cancer cell line NCI-H69. Methods Cultured cells were divided into 4 groups: antisense oligodexynucleotides(ASODN), sense oligodexynucleotides (SODN), nonsense oligodexynucleotides (NSODN) and control.The different bcl-2 oligodexynucleotides was transfected into corresponding cells using oligofectamine.The expression of bcl-2 was examined by Western blot.The apoptosis rates were measured by flow cytometry (FCM).Results The bcl-2 expression in ASODN group was significantly inhibited compared to the control group, SODN and NSODN groups, but it was not obviously inhibited in SODN and NSODN groups.The apoptosis rate of ASODN group in different concentration was (9.97±1.54) %, (15.28±1.73) % and (21.41±1.85) % respectively, it was significantly higher than that of the control group (F = 7.19-15.48,q = 5.21-7.98, P ＜0.01). Conclusion The bcl-2 ASODN could enhance cell apoptosis rate in small-cell lung cancer by blocking bcl-2 gene effectively.

Objective To explore the relationship between the hypoxia-inducible factor-1α (HIF-1α) Pro582Ser polymorphism and type 2 diabetic nephropathy (DN). Methods Two hundred and forty four subjects with type 2 diabetes were recruited. HIF-1α Pro582Ser polymorphism was detected using PCR-RFLP to analyses. Results SNPs were detected at the site of 1 285 bp of HIF-1α exon , which could turn proline to serine (Pro582Ser). T allele carrying rate was significantly higher in the patients with DN than in those with right diabetes (P<0.05) at 1 285 bp site of HIF-1αexon. By Logistic regression analysis, high HbA1c and low HDL-c were risk factors for DN and Pro582Ser was excluded in the equation. Conclusion High HbA1c and low HDL-c are risk factors for type 2 DN. HIF-1αPro582Ser SNPs may be correlated with type 2 DN, but the correlation needs further exploration.

Cardiovascular diseases, like coronary heart disease and myocardial infarction, are the most common cause of death worldwide. Chinese medicines have demonstrated rich cardioprotective activities for clinical applications. Salvia miltiorrhiza, a very important component of traditional Chinese medicine, can promote blood circulation and relieve blood stasis. Salvia miltiorrhiza is widely used in treatment of cardiovascular and cerebrovascular disease such as coronary heart disease and cerebral infarction ( CI). Tanshinone II(A), the major lipophilic components extracted from the root of S. miltiorrhiza, possesses anti-atherosclerosis, anti-cardiac hypertrophy, anti-oxidant, anti-arrhythmia and so on. This paper discusses current research status of tanshinone II(A) in cardioprotective effects.

Background Sphingosine-l-phospate (S1P) is a bioactive lipid and important messenger molecule in cells.It participates in the regulation of many biological processes,such as cell proliferation,migration,survival,differentiation,apoptosis,etc.Hypoxia is a trigger factor of choriod neovascularization (CNV) and pathological basis of many diseases,and retinal pigment epithelial (RPE) cells are involved in formation of CNV.However,the effects of S1P on proliferation and apoptosis of RPE cells are below understood.Objective This study was to investigate the influence of S1P on proliferation and apoptosis of human RPE cells under hypoxic conditions.Methods Human RPE cells line-D407 cells were cultured and passaged and generation 3-5 cells were used and divided into 6 groups.The cells were regularly cultured in the blank control group using DMEM containing 10％ fetal bovine serum.CoCl2(200.00 μmol/L) was added into the colture medium for 2 hours in the hypooxic group.S1P of different concentrations (0.01,0.10,1.00,10.00 μmol/L) were added in culture medium 2 hours after the affection of 200.00 μmol/L CoCl2.The proliferative values of the cells were detected using WST-1 method as the absorbance (A value) and the proliferative rate of different groups were calculated.The apoptosis of the cells was assayed by Hoechst staining.The results were compared among different groups.Results Cultured cells showed the round-like in shape with clear nuclei and pigment.The proliferative values (A value) was 0.91 ±0.08,0.37±0.09,0.46±0.08,0.52±0.09,0.61 ±0.06,0.70±0.10 in the blank control group,hypoxic group and 0.01,0.10,1.00,10.00 μmol/L S1P groups,respectively,with a significant difference among the groups (F=21.104,P=0.000),and A values in various S1P groups were higher than those in the hypoxiac group (all at P＜0.05).The proliferative rate was gradually raised with the increase of dose of S1P.Hoechst staining exhibited a few apoptosis cells in the blank control group,but in the hypoxic group,a lots of apoptosis cells were seen with the light-blue nuclei and condensable chromatin.However,the number of apoptosis cells was significantly decreased in various concentrations of S 1 P groups.The apoptosis rates were (1.21 ±0.08) ％,(8.99 ±0.09) ％,(6.60 ±0.08) ％,(5.95 ±0.09) ％,(4.81 ± 0.06)％ and (3.96±0.10)％ in the blank control group,hypoxic group and the 0.01,0.10,1.00,10.00 μmol/L S1P groups,respectively,with a significant difference among the groups (F =25.070,P =0.000).Compared with the hypoxia group,the cellular apoptosis rates of various S1P groups were lower (all at P＜0.05).Conclusions Under the hypoxia condition,S1P can promote the proliferation of human RPE cells and inhibit apoptosis.
