[Summary] With the increasing global aging population, osteoporosis vertebral compression fracture ( OVCF) is getting more attention as a big challenge for orthopedic surgeons.Current therapeutic options include conservative treatment, traditional open reduction and internal fixation, percutaneous vertebroplasty (PVP), and percutaneous kyphoplasty (PKP).Due to excellent clinical results on pain relief and function improvement, PVP and PKP, as minimally invasive surgical techniques, now increasingly become more popular for painful OVCF.The review focused on a brief introduction of the current status of the two procedures and a discussion of the future trends of the two techniques.

AIM: To explore the possible signal transduction pathway of 1-methyl-4-phenylpyridinium(MPP +)-induced apoptosis. METHODS: The apoptosis of SHSY5Y cells induced by MPP + was observed by acridine orange-ethidium bromide(AO-EB) staining. Western blot was used to detect the activity of JNK in SHSY5Y cells, and the antisense oligo- neucleutide of JNK were used as inhibitor of JNK. RESULTS: MPP + induced apoptosis in SHSY5Y cells. During the apoptotic process, JNK activity increased. MPP +-induced apoptosis in SHSY5Y cells was obviously inhibited by pretreatment with NAC or by transfection with antisense oligonucleotide of JNK into SHSY5Y cells. Simultaneously, decrease in JNK activity and percentage of positive cleaved caspase-3 cells in these groups were also observed. CONCLUSION: The possible signal transduction pathway of MPP +-induced apoptosis in SHSY5Y cells might be attributed to the production of ROS ,activation of JNK and then activation of caspase 3.

Objective To explore the possible molecular mechanism of Ginsenoside Rg1 preventing against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced substantia nigra neurons apoptosis in Parkinson disease(PD) mouse model. Methods C57BL mice were administrated(sc) with MPTP to produce PD mouse model.Different doses of Rg1(5.0,10.0,20.0*!mg/kg) were given(ip) prior 3*!d to MPTP in the pretreatment groups.Nissl staining,tyrosinehydroxythase(TH) immunostatining,cleaved caspase-3 immunostatining and TUNEL staining were used to observe the changes of nigra neurons,meanwhile,Western blot was used to detect the phosphorylated protein of JNK and c-Jun in substantia nigra. Results Pretreatment with Rg1 could prevent the loss of Nissl staining neurons and TH-positive neurons,inhibit JNK and c-Jun phosphorylation in SN,decrease the percent of cleaved caspase-3 and TUNEL-positive cell.Conclusion Rg1 can attenuate MPTP-induced apoptosis in substantia nigra neurons through blocking JNK signaling cascade.

Viperin is an endoplasmic reticulum (ER)-associated protein that has been identified as an innate antiviral protein. Viperin expression can be largely upregulated by viruses, interferons, and oligonucleotides such as poly I:C and lipopolysaccharides. Viperin inhibits viral replication by interactiing with host cell proteins and several viral proteins, and disrupting the cell membrane system. It shows a broad-spectrum of antiviral activity. Some viruses have developed activities that counteract the action of viperin during a long- term period of evolution with hosts by impairing viperin expression. In addition to its antiviral effects, viperin has several other biological functions. This article review the basic characteristics of viperin and the state of current research into its antiviral effects, demonstrating the rapid progress that has been made in this field.

Objective To assess the clinical effect and safety of human blood albumin in treatment of acute cerebral hemorrhage.Methods 88 patients with acute cerebral hemorrhage were randomly divided into 2 groups. Both group were given routine therapy and 45 cases in the treating group were given additional 10% human blood albumin 100 ml ivgtt once a day for 7 days.14 days served as a treatment course.Neurofunction was compared before and after treatment.Results Both the effective rate (P<0.05) and the neurofunction in the treating group were better than that of the control group (P<0.05).No advert effect happened.Conclusion Human blood albumin is an efiective and safe medicine for treatment of acute cerebral infarction.

For a long time, limited by the factors such as laparoscopic technology, and limited medical resources , the residents accepting standardized training are lack of mastery of the technology . Meanwhile, it is the key to the training of personnel training and reserve in the field for residents to contact the laparoscope as soon as possible and carry out scientific and effective training. Therefore, based on the traditional method, we have developed a new type of laparoscopic teaching system for the standardized training residents and increased and integrated the LAP GAME R operations training system and the real-time multimedia teaching platform. The preliminary practice effect is good.
