Objective To investigate the effects of treatment of proximal humeral fracture in the elderly with anatomical plate internal fixation.Methods Twenty-seven cases of proximal humeral fractures received operative treatment with anatomical plate.According to Neer classification,there were 18 patients with three-part fractures of the bone,there were 9 patients with four-part fractures of the bone.Results Twenty-seven patients were followed up for 6-24 months.According to the evaluation of Herscovici scales,the result were excellent in 17 cases,and good in 8,92.6％ (25/27) of all reductions were excellent or good.The excellent and good rate of Constant-Murley score was 88.9％(24/27 ).Conclusion It is an ideal way to treat the displaced proximal humeral fracture with anatomical plate,which can provide rigid fixation,it allows early functional treating.

Objective To explore the clinical effect of operative treatment for grade Ⅳ pronation-external rotation ankle injury.Methods 60 patients with pronation extorsion type Ⅳ degree of ankle injury were selected as the research subjects.According to the digital table,they were divided into two groups,30 cases in each group.The group A adopted ordinary steel plate,the group B adopted locking plate fixation.The clinical curative effect,postoperative recovery index,AOFAS score and complications were observed.Results The total effective rate of group A was 93.3％,which of group B was 90.0％,the difference was not statistically significant (x2 =0.218,P ＞ 0.05).The swelling subsided time [(24.2 ± 5.0) d vs.(22.9 ± 4.1) d],fracture healing time [(42.4 ± 9.5) d vs.(41.3 ± 9.4) d],postoperative recovery time of walking [(46.6 ± 9.2) d vs.(45.7 ± 9.0) d],AOFAS score [(87.3 ± 2.6) vs.(88.4 ±2.2)] between the two groups had no statistically significant differences(t =1.101,0.451,0.383,1.769,all P ＞0.05).The group A had 1 case in infection,the incidence rate of complications was 3.3％.The group B had no complication.The difference was not statistically significant in the incidence of complications between the two groups (x2 =1.017,P ＞ 0.05).Conclusion In the operative treatment for patients with grade Ⅳ pronation-external rotation ankle injury,whether choose ordinary steel plate fixation,or choose the locking plate fixation,the clinical effects of the two methods are both good,and the postoperative healing is fast.

Cerebral ischemia-reperfusion results in damage on neuron, leading to genes and proteins related to apoptosis activation. At the same time, generous cytokines released after cerebral ischemia-reperfusion can induce the apoptosis of the neuron. Many current studies have showed that the major damage mechanisms on apoptosis of the neuron are mitochondrion impairment, calcium overload, increased levels of oxygen radicals and so on. The advance research on the mechanism contributes to explore new neuroprotective drugs, and further identify the target and therapeutic effect of drug treatment.

Objective To investigate the effects of morroniside on activation of caspase-3 in rats with focal cerebral ischemia/reperfusion. MethodsThe model was induced with occlusion of middle cerebral artery with suture embolus, ischemia for 30 min, and reperfusion for 72 h in rats. Vitamin E used for the positive control. The activity of caspase-3 was detected with spectrophotometry. ResultsCompared with sham group, the caspase-3 activity increased obviously in model rat. Compared with model group, Morroniside (30 mg/kg,90 mg/kg,270 mg/kg) decreased the activation of caspase-3 remarkably, which was dose-dependent (P<0.05). ConclusionMorroniside may reduce apoptosis by decreasing the activation of caspase-3 in rats.

ObjectiveTo investigate the effects of morroniside on IL-1β in rat cortex with focal cerebral ischemia/reperfusion.MethodsThe animal model was induced by occlusion of middle cerebral artery with suture embolus, ischemia for 30 min, and reperfusion for 72 h in rats. The content of IL-1β was detected with enzyme linked immunosorbent assay(ELISA).ResultsCompared with sham group, the content of IL-1β increased obviously in model rat. Compared with model group, morroniside(30 mg/kg, 90 mg/kg, 270 mg/kg) and colchicine (0.06 mg/kg) decreased the content of IL-1β significantly (P<0.001).ConclusionMorroniside may protect the cortex from inflammatory factor IL-1β.

Aim The goal is to make a further comprehension of the pathogenesis of Parkinsons disease (PD) and hence add further knowledge for PD diagnosis by observing the functions of nitric oxide (NO) in striatum (STR). Method Microelectrodes were used to observe the effects of sodium nitroprusside (SNP), L-glutamic acid (GLU) and ?-aminobutyric acid (GABA) on STR neurons' spontaneous firing rates, and at the same time, we observed the effects of NO on GLU and GABA. Results 77% (51/66) of the tested neurons were excited by SNP, NO synthase inhibitor L-NAME antagonized the excitatory effect of SNP. Duringthe periods of microelectrophoresis GLU and GABA, SNP amplified the excitatory effect of GLU and weakened the inhibitory effect of GABA. L-NAME antagonized the excitatory effect of GLU.Conclusion These results demonstrated clearly that NO, GLU and GABA functions might converge in the same STR neurons. NO and GLU functions are excitatory whereas GABA function is inhibitory on the firing activities in STR neurons.

Objective To explore the role of chemokine CCL18 in the occurrence and development of children allergic diseases. Methods The serum levels of CCL18 in 87 children cases of allergic asthma,64 cases of allergic rhinitis,46 cases of allergic con-junctivitis and contemporaneous 50 health students with physical examination as the control group were measured by ELISA and re-measured after 6-month treatment.The detection results were statistically analyzed with combining the clinical related detection data by adopting SPSS18.0 statistical software and t-test.Results The serum levels of CCL18 in the children allergic asthma,allergic rhinitis and allergic conjunctivitis groups were remarkably higher than those in the control group with statistical differences(P <0.05);the levels of CCL18 in the severe groups were remarkably higher than those in the mild and moderate groups with statistical difference(P <0.05);the levels of CCL18 after 6-month treatment in 3 groups were significantly decreased compared with before treatment with statistical difference(P <0.05).Conclusion The serum level of CCL18 is significantly associated with the severity of illness and significantly decreased after treatment,which indicating that the CCL18 detection has the important value in the diag-nosis,severity evaluation and treatment effect monitoring of children allergic diseases.
