OBJECTIVETo evaluate the clinical efficacy of manipulative reduction combined with percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF) using meta-analysis method, in order to provide a reference for clinical treatment.

METHODSA systematic computer-based search (from January 1987 to April 2014) from CNKI, Wanfang database, Web of Science and PubMed were performed for the collection of controlled clinical researches on manipulative reduction combined with PVP or PKP in treating OVCF. The quality of selected researches was evaluated. Meta-analysis was adopted to evaluate visual analog scale, Cobb angle, anterior height ratio of the injured vertebra.

RESULTSA total of 7 researches of 410 patients were included in the present analysis, there were 5 RCTs and 2 non-RCTs and all come from China. Manipulative reduction combined with PVP could got better improvement in Cobb angle (WMD=-7.35; 95%CI: -12.15, -2.54) and anterior height ratio of the injured vertebra (P<0.01) than simple PVP, but no significant difference was found in improvement of visual analog scale (WMD=-0.01; 95%CI: -0.45, 0.42). There were no significant differences in the improvement of visual analog scale, Cobb angle, anterior height ratio of the injured vertebra between manipulative reduction combined with PKP and simple PKP (P>0.05).

CONCLUSIONCompared with simple PVP, manipulative reduction combined with PVP may result in more clinical efficacy on the improvement of Cobb angle and anterior ratio of the injured vertebra. And compared with simple PKP, manipulative reduction combined with PKP has no obvious advantages on the improvement of visual analog scale, Cobb angle, anterior height ratio of the injured vertebra. However, the number and quality of the literatures, may resulted in the effect of mistrust, so more large sample and high-quality RCTs are needed in future.

Purpose To investigate the expression of insulin-like growth factorIImRNA binding protein 3 ( IMP3 ) and microvessel density (MVD) in squamous carcinoma of the cervix (SCC) and analysis their relationship in SCC. Methods The expression of IMP3 and MVD was examined by immunohistochemistry SP method in normal cervical epithelium ( NCE) , low-grade cervical intraepi-thelial neoplasia (CIN-L), high-grade cervical intraepithelial neoplasia (CIN-H) and SCC. Results (1)The positive expression rates of IMP3 in NCE, CIN-L, CIN-H, SCC tissues were 0(0/15), 0(0/11), 37.5%(9/24) and 86.0%(43/50), the difference was statistically significant (x 2 =53.345, P=0.000). IMP3 expression was significant difference among NCE and CIN-H, SCC (P<0.008 3), and that was also among SCC and CIN-L, CIN-H (P<0.008 3). (2)The MVD count was increased with the development of cervical squamous lesion, there was significant difference among those groups (F=145.968, P<0.01), and the difference was al-so statistically significant between every two groups (P<0.05). The positive expression of IMP3 and MVD count in 50 cases of SCC tissues showed statistical difference in different pathologic grade, lymph node metastasis, and depth of tumor invasion groups ( P<0.05), but didn't in different patients’age groups (P>0.05). And the positive expression of IMP3 was closely related with MVD count in SCC tissues (rs =0.323, P<0.05). Conclusion IMP3 plays an important role in the occurrence, infiltration and metasta-sis of SCC, and the abnormal expression of IMP3 may relate with the angiogenesis of tumors.

AIM and METHOD: In terms of difference value between bleeding blood volume that caused hemorrhagic shouk (HS) and residual blood volume at 2 h after HS, showed that HS at 5.3 kPa level was compen- satory and at 4.0 kPa level was decompensatory. Comparing some blood changes between HS two levels and their changes while pretreated with captopril (Capt. ) to reduce the release of angiotensin Ⅱ (Ang-Ⅱ), so as to inveshgate the significance of Ang - Ⅱ during HS. RESULTS: The residual blood volume in 4.0 kPa HS + Capt. group are again from near "zero" value in simple 4.0 kPa HS group. In both two HS level groups found blood dilution and was not influenced by pretreating with Capt.; contents of K+ and aldosterone increased, but Na+ had no changes, in Capt. + HS group, the former two contents reduced and Na+ had no changes comparing with each HS group. In two HS groups, the bind lactate, lactic dehydrogenase (LDH), blood urea nitrogen (BUN) increased and had more increment in 4.0 kPa HS group. All these changes could be prevented by pretreating with Capt. The blood glucose in 5.3 kPa HS group increased markedly and Capt. had no influence on it, but decreased extremely in 4.0 kPa HS group and Capt. could make it re - increased. CONCLUSIONS: Artery blood pressure (ABP) at 5 .3 kPa level was compensatory HS and ABP at 4 .0 kPa level was decompensatory HS, some changes on decompensatory HS were more serious and severe than compensatory HS, Capt. has protective effects on some changes during HS and could prolong the survival time of decompensatory HS, all that indicated the increment of Aug - Ⅱ is an important pathogenetic factor during HS.

OBJECTIVE CYP2 family including CYP2C and CYP2J is the predominant arachidonic acid (AA) epoxygenase, and the epoxidation of AA produces four regioisomeric cis-epoxyeicosatrienoic acids (5,6-, 8,9-, 11,12-, and 14,15-EET). Human CYP2J2 is one of the main CYP isoforms expressed in brain, but CYP2C8 was present at a low level. The aim of this study is to investigate the roles of brain CYP2J in Parkinson disease. METHODS Rats received the right-unilaterally injection with concentrated LV-CYP2J3 or LV-EGFP in the substantia nigra (SN) at 3 d before LPS or 6-OHDA treatment. The animals were tested for rotational behavior with the dopaminergic agonist apomorphine dissolved in sterile saline at 14 and 21 d after LPS injection. The influence of CYP2J-dependent derivative, 14,15-EET, on the genes related with oxidative stress was assayed in SH-SY5Y cells. RESULTS CYP2J overexpression or 14,15-EET treatment significantly increased the levels of SOD1, CAT, GPX1, NRF2 and KEAP1 in neurons. TLR4- MyD88 signaling pathway was involved the down- regulation of CYP2J by LPS. The binding of p-CREB with the promoter of CYP2J was inhibited by the LPS treatment. The loss of dopami?nergic neurons in the right SN induced by LPS or 6- OHDA was significantly decreased by CYP2J3 transfection at 21 d after LPS injection. Compared with LPS or 6-OHDA group, the number of the rotation of rats was decreased by 42.6% and 60.7% by CYP2J3 transfection at 14 d after LPS or 6-OHDA injection;meanwhile, the rotation number was decreased by 12.7% and 21.3% at 21 d. The accumulation of alpha synuclein induced by LPS was significantly decreased by CYP2J3 transfection. The mRNA levels of SOD1, CAT, GPX1, NRF2 and KEAP1 in SN were decreased by LPS, which was attenuated by the injection of LV-CYP2J3. CONCLUSION Brain CYP2J can play a protective role in the damage of the inflammation and oxidative stress to the dopaminergic neurons. Brain CYP2J- dependent derivatives from AA may have therapeutic effects in Parkinson disease via the up- regulation of the antioxidant system in neurons.

OBJECTIVETo observe the effect of cold or hot properties of traditional Chinese medicines (TCM) on biological effect indexes, and analyze the contribution of variables on cold or hot properties, in order to preliminarily establish the discrimination mode for the biological effects of cold or hot properties.

METHODRats were randomly divided into the blank control group, cold TCM groups (Coptidis Rhizoma, Scutellariae Radix, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix and Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex and Evodiae Fructus), and orally administered with 10 mL x kg(-1) of corresponding TCM water decoctions for 30 d, twice a day. Altogether 53 biological effect indexes correlated to cold or hot properties of traditional Chinese medicines were founded by searching literatures. The data warehouse were established by using data-mining software Clementine12.0. Data of the blank control group, cold TCM groups (Coptidis Rhizoma, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix, Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex) were selected into a training set. C5.0 algorithm and C&R classification and regression algorithm were adopted to define the importance of variable, create the decision trees, and test hot or cold properties of Evodiae Fructus and Scutellariae Radix.

RESULTAccording to C&R classification and regression algorithm, SDH activity of livers was the most important hot or cold property, with the significance closed to 30%. It was followed by triglyceride, liver Na' -K' -ATPase enzyme, muscle glycogen and platelet distribution width, with the accuracy up to 97.39% in models. C5.0 algorithm showed that liver SDH activity was the most important hot or cold property, with the significance closed to 40%. It was followed by triglyceride, GOT, muscle glycogen and liver Na(+)-K(+)-ATPase enzyme, with the accuracy up to 98.26% in models. The possibilities that Evodiae Fructus is in hot property and Scutellariae Radix is in cold property were 100. 00% and 77.78% by using both C&R classification and regression algorithm and C5.0 algorithm.

CONCLUSIONThe SDH activity of liver is the most important biological effect index to distinguish cold and hot properties of TCMs. The discrimination pathway or mode of cold and hot properties is closely related to energy metabolism.

Objective To observe the changes of neural blood flow when oppressed with different pressures and at different sites in rat's sciatic nerve.MethodsThe sciatic nerve compression model of rat with pressure and time controlled simultaneously was established.The changes of neural blood flow were observed by oppressing the sciatic nerve with five grades pressures using Gasbag.The rats were randomly divided into the distal compression group and proximal compression group,and the changes of neural blood flow were observed in each group.ResultsThe neural blood flow changed significantly(P<0.05) when the sciatic nerve was oppressed with different pressures and it had the decreasing tendency with the pressures increasing.The neural blood flow of each group decreased obviously(P<0.01).The effect of oppressing distal nerve on neural blood flow was more obvious than that of oppressing proximal nerve(P<0.01).ConclusionMechanical compression can influence the neural blood flow obviously.The distal vessels of sciatic nerve are the major sources of nerve blood supply.

OBJECTIVE Neuroinflammation plays a critical role in neurodegenerative disorders, although the inflammation may not the initiating factor. Parkinson disease (PD) is characterized patho?logically by the accumulation of alpha synuclein (α-syn) and the loss of the dopamine (DA) neurons in the substantia nigra (SN), which has been reported to be induced by the stereotaxic injection of lipopolysaccharide (LPS) to the SN region in rodents. This study is to investigate the therapeutic benefit of the inhibition of miR-873 in PD. METHODS Rats received the right-unilaterally injection with concentrated LV-sponge or LV-EGFP 3 d before LPS treatment, 7 or 14 d after LPS treatment. The animals were tested for rotational behavior with the dopaminergic agonist apomorphine dissolved in sterile saline at 21 d after LPS injection. The regulation of miR-873 on the genes related with cholesterol transport and inflammation was assayed in SH-SY5Y cells and U251 cells. RESULTS TLR4-MyD88 signaling pathway was involved the regulation of miR-873 by LPS. The luciferase assay showed that HMGCR, ABCA1 and A20 were down- stream genes of miR- 873. The transfection of miR- 873 decreased the cholesterol levels in cell membrane, but increased in lysosome in SH-SY5Y cells. Compared with the control SH-SY5Y cells, cholesterol levels were higher in lysosome with α-synuclein overexpression or LPS treatment. The transfection of miR-873 increased the α-syn levels in lysosome in cells with α-synuclein overexpression. The loss of dopaminergic neuorns induced by LPS was significantly respectively decreased by 22.8%, 35.6% and 57% after the inhibition of miR-873 at 3 d before LPS treatment, 7 or 14 d after LPS treatment. Compared with LPS-treated group, the number of the rotation of rats was decreased by 60.4%, 33.5% and 13.2% after the inhibition of miR-873 at 3 d before LPS treatment, 7 or 14 d after LPS treatment. The inhibition of miR-873 significantly decreased accumulation of α-syn. The mRNA levels of HMGCR, ABCA1 and A20 in SN were decreased by LPS treatment, which was attenuated by the injection of LV- sponge. CONCLUSION The selective regulation of miR- 873 can protect the dopaminergic neurons from the LPS-induced damage. The inhibition of miR-873 can attenuate the relocation of cholesterol in lysosome and the accumulation of α-syn in neurons induced by LPS via the regulation of HMGCR, ABCA1 and A20.
