OBJECTIVETo investigate the influence of adrenoreceptor beta-agonists terbutaline on gene expression of vascular endothelial growth factor (VEGF) in rat astrocyte after induction by norepinephrine (NE) and burn serum.

METHODSThe sera of normal and burn rats were separated for use. Primary astrocytes of brain tissue were isolated from neonatal 1-3 d rats and cultured and divided into following groups: (1) CONTROL GROUP: with 10% normal rat serum in the culture medium. (2) NEl, NE2, NE3 groups: with 10% burn rat serum and 10, 20, 50 micromol/L NE in the culture medium, respectively. (3) TBN1, TBN2, TBN3 groups: with 10% burn rat serum and 10, 20, 50 micromol/L NE and 10, 20, 50 micromol/L terbutaline in the culture medium, respectively. The mRNA and protein expression of VEGF in each group were determined with real-time PCR and Western blotting, respectively.

RESULTSThere was a low protein expression of VEGF in control group, but it increased slightly in NE1 group, and then increase gradually in NE2, NE3 groups, and it was obviously increased in TBN1, TBN2, TBN3 groups. The mRNA expression of VEGF in NE1, NE2, NE3 groups were [(13.26 +/- 0.03), (10.37 +/- 0.04), (14.87 +/- 0.55) copies/g], respectively, which were significantly higher than that of control [(5.72 +/- 0.12) copies/g, P < 0.01]. In addition, the expression of VEGF mRNA in TBN1, TBN2, TBN3 groups was higher than that in control group, and expression of VEGF mRNA [(13.39 +/- 0.19), (15.77 +/- 0.11), (16.00 +/- 0.07) copies/g] was gradually increased, which showed obvious difference between TBN2 and NE2, and also between TBN3 and NE3 groups (P < 0.01).

CONCLUSIONTerbutaline can increase gene expression of VEGF in rat astrocytes after induction by NE and burn serum.

Glioma is the most malignant tumor in the brain, the origin of glioma is still unknown. Recently some papers indicated that glioma may be developed from cerebral cavernous malformation (CCM). We describe a man with a right temporal lobe CCM, after gamma-knife radiotherapy, the patient developed a low-grade astrocytoma in the area of the preexistent CCM. This case, together with other reports, may indicated an oncogenetic properties of CCM, and we proposed that CCM may be a pre-glioma lesion.

OBJECTIVETo analysis the early complications of tibial fracture and its related factors, and propose a solution.

METHODSFrom December 2003 to December 2013,38 patients with early complications of tibial plateau fracture after operation were retrospectively analyzed. There were 35 males and 3 females, aged from 37 to 69 years old (averaged 42.3 years). According to Schatzker classification, 3 cases were classified as type II, 2 cases as type III, 2 cases as type IV, 19 cases as type V, 12 cases as type VI. The intervals between injury and operation ranged from 9 hours to 9 days, 26 cases within 3 days. Fifteen cases were treated with internal fixation of plates and 23 were treated by plate fixation and bone transplantation. Early complications included skin necrosis in 15 cases, infection in 6 cases, osteofascial compartment syndrome in 3 cases, common peroneal nerve injury in 2 cases, the superficial peroneal nerve injury in 3 cases, popliteal artery injury in 2 cases, loss of reduction in 7 cases.

RESULTSThe wound of 14 cases healed at the first stage and 24 cases healed delay. Hospitalization days ranged from 7 to 67 days (averaged 25.6 days). All patients were followed up for 12 to 36 months with an average of 16.4 months. The fracture healing time ranged from 3 to 9 months (averaged 6.9 months). According to Merchant knee function evaluation criteria, the results were excellent in 19 cases, good in 12, fair in 5 and poor in 2.

OBJECTIVETo study the correlation between glucose-6-phosphate dehydrogenase (G-6-PD) activities and three common mutations of G-6-PD gene G1388A, G1376T and A95G and investigate the effects of G-6-PD gene mutations on neonatal jaundice in Nanning, Guangxi.

METHODSOne hundred and twenty-four neonates from Nanning, Guangxi, with hyperbilirubinemia were enrolled. The ARMS-PCR and PCR/REA methods were used to determine G-6-PD gene mutations. G-6-PD activities were measured using the NBT method. The incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth were compared between the neonates with different genotypes and between the G-6-PD mutation and normal groups. The risk of blood serum bilirubin >340 mumol/L was evaluated by logistic regression analysis.

RESULTSOf the 124 cases, gene mutations were found in 37 cases, including G1388A (n=20), G1376T (n=14), A95G (n=4) and G1388A+A95G (n=1). Five cases (25%) showed normal G-6-PD activities in the G1388A gene mutation group and 4 (29%) had normal G-6-PD activities in the G1376T G1388A gene mutation group. All of 4 cases of A95G G1388A gene mutation showed a deficiency of G-6-PD activities. There were no significant differences in the incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth between the G1388A and G1376T G1388A gene mutation groups. The incidence of acute bilirubin encephalopathy, the peak bilirubin concentration 72 hrs after birth and the risk of serum bilirubin >340 micromol/L in the G-6-PD mutation group were not different from the normal group.

CONCLUSIONSG1388A, G1376T and A95G are common G-6-PD gene mutations in Nanning, Guangxi. The false negative results may be received when the NBT method is used for diagnosis of G-6-PD deficiency. There are similar effects on the incidence of acute bilirubin encephalopathy and the peak bilirubin concentration 72 hrs after birth between different gene mutation groups. G-6-PD gene mutations alone may not contribute to the development of acute bilirubin encephalopathy and the changes of peak bilirubin concentration 72 hrs after birth and the risk of serum bilirubin >340 micromol/L.
