With high morbidity and mortality,nosocomial bacterial meningitis(NBM)is a kind of serious nosocomial infection.Post-neurosurgical patients are at a high risk of this infection andNBM in-creases hospital stay and medical expense obviously.In this article,we reviewed recent studiesonpathogen-esis,treatment,and research progress of NBM in neurosurgical patients,and presented unresolved ques-tions and research direction in the future.

Percutaneous coronary intervention(PCI) has been a mainstay in the management of coronary artery disease since its introduction in the late 1970s.Bare-metal stents and,more recently,first-generation drug-eluting stents(DES),such as sirolimus-eluting(Cypher) and paclitaxel-eluting stents(Taxus),have further improved results of percutaneous coronary intervention by improving early results and reducing the risk of restenosis.There are currently debates on the safety of these first-generation DES,given the potential for late stent thrombosis which is a first-generation drug-eluting stent of the largest security issue,especially after discontinuation of dual antiplatelet therapy.Next-generation DES such as everolimus-eluting stents(Xience V) holds the promise of superior anti-restenosis efficacy as well as long-term safety.This review makes a presentation of the evidence-based clinical research according to everolimus-eluting stents(Xience Ⅴ).

BACKGROUND:Myocardial apoptosis can lead to many kinds of heart diseases, but most of the conventional treatments cannot get desired effects. The emergence of cardiac stem cel related theory that subverts the previous view of myocardial cel s provides a new idea for the treatment of a variety of heart diseases.
OBJECTIVE:To investigate the protective mechanism of cardiac stem cel s in myocardial apoptosis.
METHODS:Cardiac stem cel s were isolated from five neonatal rats. Another 20 Wistar rats were selected to make myocardial infarction models, and then model rats were equivalently randomized into observation and control groups. One day after modeling, rats in each group were given injection of cardiac stem cel s or culture solution. Fourteen days after injection, myocardial apoptosis index was calculated and expression of apoptosis-related proteins was detected in both groups.
RESULTS AND CONCLUSION:After continuous 3 days of culture, a completely spread growth in the cardiac tissues was visible, and a smal amount of cel s similar to fibrocytes climbed out from the cardiac tissue sample. These cel s isolated using magnetic bead method were sub-cultured for 5 days, and found to be regrouped again. Compared with the control group, the apoptotic index, Fas and Fasl expression were significantly lower (P<0.05), and Bcl-2 expression was significantly higher in the observation group (P<0.05). Al these findings show that cardiac stem cel transplantation can effectively regulate the expression of apoptosis-related proteins and inhibit the apoptosis of myocardial cel s in rats with myocardial infarction.

Objective:To study the protective effect of electro-acupuncture on glutamate(GLU),glycine(GLY),aspartate(ASP)and NF-?B expression in rat with cerebral ischemia reperfusion.Methods:The middle artery occlusion(MCAO)model was established and high pressure liquid chromatography(HPLC)fluorescence assay was used to detect contents of glutamate(GLU),glycine(GLY)and aspartate(ASP)in rat brain.The effect of electro-acupuncture on the nervous dysfunction score,the water content of cerebral constitution and the expression of NF-?B were observed.The group with non-acupoint group was as control.Results:The nervous dysfunction score,the water content of cerebral constitution,NF-?B,GLUand ASP in model group were higher than those of the sham-operated group.GLY levels had no obvious changes,there was no significant diference between the model group and the non-acupoint group.The nervous dysfunction score,the water content of cerebral constitution,the expression of NF-?B,GLU and ASP in electro-acupuncture group were lighter than that of the model group,GLY levels had no obvious changes.Conclusion:Electro-acupuncture could protect brain cell from damage after focal cerebral ischemia reperfusion injury by inhibiting the cerebral expression of NF-?B and excitatory amino acid.

OBJECTIVETo evaluate clinical outcomes of anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction under arthroscopy and repair of the injured posteromedial complex structure of the knee joint in the treatment of posterolateral knee dislocation with multiple ligament injuries.

METHODSFrom March 2008 to August 2012,22 patients (16 males and 6 females, ranging in age from 20 to 53 years old, with an average of 30.5 years old) with posterolateral dislocation of the knee were treated with primary reconstruction of ACL and PCL, combined with the repair of injuries in the posteromedial complex and soft-tissue. Eight patients had injuries caused by sports,5 patients road accidents and 9 patients falling down. The ACL was reconstructed using the gracilis and semitendinosus tendons. The PCL was reconstructed using LARS artificial ligaments (14 cases), or gracilis and semitendinosus tendons (8 cases). Suture repair was performed in 17 patients with posteromedial ligament injuries,and self-semitendinosus strengthening operations were performed in 5 patients. Continuouspassive montion (CPM) and active exercises were executed after operation at early stage. The IKDC and Lysholm system were used to evaluate therapeutic effects.

RESULTSAll the patients were regularly followed up, and the duration ranged from 11 to 56 months (averaged, 39 months). According to the IKDC scale,9 patients got a grade A result, 10 got a grade B result, and 3 got a grade C result. The IKDC subject score was 89.6±3.1 and the Lysholm scores was 90.7±1.8 at the latest follow-up, which were both better than those before operation.

CONCLUSIONReconstructing the ACL and PCL and repairing injured posteromedial complex of the knee followed by an active rehabilitation is an effective method to treat posterolateral knee dislocation.

OBJECTIVE: To study the effects of Naomaitong Recipe, a compound Chinese herbal medicine, on the expressions of nuclear factor-kappaB (NF-kappaB) and nitric-oxide synthases (NOSs) in brain tissue after focal cerebral ischemia reperfusion in aged rats and the dosage-effect relationship. METHODS: We adopted the middle cerebral artery occlusion (MCAO) in aged rats as the focal cerebral ischemia model, with 3-hour ischemia and 12-day reperfusion, and observed the changes of the nerve dysfunction score, the water content of cerebral constitution and the expressions of NF-kappaB, heat-shock protein 70 (HSP70) and NOSs in cerebral cortex. RESULTS: The nerve dysfunction score, the water content of cerebral constitution, the expressions of NF-kappaB, HSP70, neuronal nitric-oxide synthase (nNOS), endothelial nitric-oxide synthase (eNOS) and inducible nitric-oxide synthase (iNOS) in the untreated group were higher than those of the sham-operated group. The nerve dysfunction score, the water content of cerebral constitution, the expressions of NF-kappaB, iNOS and nNOS were lower, while the expressions of HSP70 and eNOS were higher in the high-, medium- and low-dose Naomaitong-treated groups and nimodipine-treated group than those of the untreated-group. The nerve dysfunction score and the expression of nNOS were lower, while the expression of eNOS was higher in the medium-dose Naomaitong-treated group than those of the nimodipine-treated group. The expressions of HSP70 and eNOS were higher, while the other indices were lower in the medium-dose Naomaitong-treated group than those of the low-dose Naomaitong-treated group. CONCLUSION: Naomaitong Recipe can protect the brain cells from damage after focal cerebral ischemia reperfusion injury by adjusting the expressions of NF-kappaB, HSP70 and NOSs, and the medium-dose Naomaitong Recipe is more effective.
