OBJECTIVETo compare clinical outcomes of bilateral transpedicular balloon kyphoplasty for the treatment of ordinary osteoporotic vertebral compressive fracture (OVCF) and severe osteoporotic vertebral compressive fracture.

METHODSFrom Junary 2009 to Febuary 2011, 60 patients (70 vertebrae) with osteoporotic vertebral compressive fracture were included. All patients were treated by bilateral transpedicular balloon kyphoplasty combined with postural reduction, including 10 males and 50 females aged from 59 to 90 years old with an average of 72.1 years old. In ordinary osteoporotic vertebral compressive fracture group, there were 38 patients (44 vertebrae) including 7 males and 31 females aged from 59 to 87 years old with an average of (71.8±6.1) years old. There were 6 patients with two vertebral fractures, 1 vertebra in T9, 5 vertebrae in T10, 7 vertebrae in T11, 13 vertebrae in T12, 9 vertebrae in L1, 4 vertebrae in L2, 4 vertebrae in L3, 1 vertebra in L4. While in severe osteoporotic vertebral compressive fracture group, there were 22 patients (26 vertebrae) including 3 males and 19 females aged from 63 to 90 years old with an average of (72.6±7.2) years old. There were 4 patients with two vertebral fractures, 1 vertebra in T9, 2 vertebrae in T10, 3 vertebrae in T11, 9 vertebrae in T12, 6 vertebrae in L1, 3 vertebrae in L2, 2 vertebrae in L3. Operative time, volume of bone cement injection, and vertebral height and changes of Cobb angle before and after operation were observed and compared. Postoperative average recovery rate of vertebral height and correct degree of Cobb angle were caculated and compared, VAS scoring were used to evaluate therapeutic effect.

RESULTSAll operations were completed sucessfully, and pain were relieved at 72 h after operation. All patients were followed up from 6 to 13 months with an average of 10.1 months. Postoperative vertebral height, Cobb angle and VAS score were improved better than that of before operation (P<0.05). Operative time in ordinary group was shorter than severe group, while volume of bone cement injection was more than that of severe group. Average recovery rate of vertebral height and correct degree of Cobb angle in ordinarty group was better than that of in severe group (P<0.05). There was no significant differences between two groups in VAS scores before and after operation (P> 0.05). Three cases (3 vertebrae) ocurred bone cement leakage in ordinarty group, while 5 cases (5 vertebrae) ocurred bone cement leakage in severe group, and there was no meaning between two groups (P>0.05).

CONCLUSIONKyphoplasty could receive satisfied curative effect in treating ordinary and servere patients with osteoporotic vertebral compressive fracture, but recovery of vertebral height and correct degree of Cobb angle in ordinary gourp was better than that of in servere group.

Background Myopic maculopathy leads to visual function damage.Conventional methods for the identification of choroidal neovascularization (CNV) of myopic maculopathy are fundus fluorescine angiography (FFA) and spectral-domain OCT (SD-OCT),but FFA is an invasive process and SD-OCT is incapable to image CNV well.OCT angiography (OCTA),a novel and non-invasive vascular technique,appears to be dominant in enface imaging of CNV,however,its clinical value remains to be evaluated.Objective This study was to evaluate the application of OCTA in imaging CNV of myopic maculopathy.Methods A prospective serial cases-observational study was performed.Forty-two eyes of 40 patients of myopic maculopathy were included in Ophthalmic Center,Renmin Hospital of Wuhan University from January to October 2015,with the diopter (-10.5 ± 3.74) D.Comperehensive optical and imaginal examinations were carried out in all the eyes,including fundus photography,FFA,SD-OCT and OCTA.Ranibizumab (0.5 mg/0.05 ml) was intravitreally injected in 35 eyes of 35 patients under the informed consent and SD-OCT and OCTA were examined 1 day,1 week and subsequent each month after injection.FFA was examined 1 month after injection.The patients were followed-up for 1-6 months to evaluate the clinical values of OCTA in monitoring the CNV of myopic maculopathy.This study followed the Helsinki Declaration and was approved by the Ethics Committee of Renmin Hospital of Wuhan University.Written informed consent was obtained from each patient prior to any medical examination.Results All the affected eyes showed dye leakage in CNV lesions by FFA and high reflection signal of abnormal choroidal vascular network throughout retinal pigment epithelium by SD-OCT.Clusters of high signal CNV image was clearly visible in the lesions by OCTA,and these signals were able to be displayed on both choriocapillary layer and outer layer of retina more clearly than FFA in 31 eyes of 31 patients.In 35 eyes of 35 patients received intravitreal injection of ranibizumab,CNV images on both choriocapillary layer and outer layer of retina from OCTA shrinked 1 week after injection and the lesions were stable 1 month after injection.Conclusions OCTA can display CNV of myopic maculopathy on the retinal outer layer and choriocapillary layer more clearly than FFA.Significant changes in the CNV net can be observed by OCTA 1 week after intravitreal injection of ranibizumab.OCTA plays an important role during the following-up of CNV therapy.

Medical students will be the clinicians in the future.The medical moral education and the moral character formation will directly influence their medical careers.It is extremely important for the medical students to know basic theory of the medical moral and develop their character by strengthening the medical moral and criterion education,especially in the time of increasing conflicts between doctors and patients.

Objective To observe effects of aqueous extractive of Clarke boea herb on mice with gastric ulcer, and provide basis for clinical application.Methods Gastric ulcer model was induced by reserpine. The mice were divided into normal group, model group, ranitidine group, low and high dose of Clarke boea herb groups. Mice in treatment groups were given corresponding drugs by gavage, and the normal group and control group were given the same amount of saline for 4 weeks. The area of gastric ulcer, serum proinflammatory cytokines gastric juice volume, gastric juice acidity, iNOS and COX-2 gene expressions were detected.Results Compared with control group, the gastric ulcer area in low and high dose of Clarke boea herb groups decreased significantly. Clarke boea herb increased the SS and VIP, decreased the MOT and SP serum levels (P<0.05,P<0.01). Clarke boea herb reduced the levels of serum proinflammatory cytokines of IL-6, IL-12, TNF-α and IFN-γ(P<0.05,P<0.01). Clarke boea herb also decreased the genetic expressions of iNOS and COX-2 (P<0.05,P<0.01).ConclusionClarke boea herb has good gastric ulcer preventive effects, and the high dose of Clarke boea herb group showed the best efficiency.

Objective To observe effects of electro-acupuncture (EA) on the expression of apoptosis related protein B-cell lymphoma/leukemia gene 2 (Bcl-2) and Bcl-associated protein X (Bax) in the hippoeampal CA1 region of rats with cerebral infarction,and on their behavior. MethodsAn animal model of cerebral ischemia was established by right side middle cerebral artery occlusion using thread in 48 male,adult Wistar rats,who were then randomly divided equally into an EA group and a control group.Both groups were sub-divided into 1 week,2 weeks and 3 weeks subgroups.The EA group began receiving EA 24h after the occlusion,applied at the Baihui (DU20) and Dazhui (BU14) points,once daily,for one,two or three weeks.The control group was reared conventionally and was not given any special treatment.The rats'learning and memory,motion and neural function were evaluated.The expression of Bcl-2 and Bax in the CA1 region of the hippocampus on the infarcted side and changes of apoptosis indexes were detected using immunohistochemical techniques.ResultsThe learning,memory,motion and neural function of the EA group rats were better on average than those of the control group at all observation time points.The expression of Bcl-2 protein increased along with reduced expression of Bax protein in the EA group significantly more than among the controls.TUNEL positive cells in the CA1 region of the hippocampus were reduced significantly in the EA group compared with the control group.ConclusionsBehavioral ability after cerebral infarction can be improved by EA at the Baihui (DU20) and Dazhui (BU14) points.EA can up-regulate the expression of Bcl-2 and down-regulate the expression of Bax and reduce TUNEL positive cells in the CA1 region of the hippocampus after cerebral infarction,which might be the mechanism of its neuroprotection.

Through comparative study on Naotaifang containing serum and plasma proteomics (peptide), this article revealed differential proteins (peptides) in the Naotaifang. The characteristics of differential proteins were identified with mass spectrometry. It provides scientific evidences for the pharmacodynamic material basis and Chinese herbal medicine plasma pharmacological method development in the exploration of Naotaifang. A total of 20 healthy adult SD rats were randomly divided into the control group, Naotaifang treatment group according to their weights. Ten rats in each group. Intragastric administration of medication was given for seven consecutive days. Before surgery, rats were fed with water but without food. One hour after the last drug administration, 10% chloral hydrate was injected for intraperitoneal anesthesia. Blood was taken through the common carotid artery. Serum and plasma samples were made after blood was taken from each rat. Serum and plasma samples of five rats were randomly selected from each group. And the two-dimensional electrophoresis (2-DE) technique was used in the comparative study of serum pro-teomics (peptide). The 300 DPI scanning and PDQuest 7.3.0 were used in the analysis. The ESI-MS/MS was used to identify important differences in proteins and screen characteristic serum and plasma protein. The results showed that 20 differential proteins of 5 plasma samples were identified. There were 15 types of proteins expressing up-regulation and 5 types expressing down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum, 19 differential proteins of 5 plasma samples were identified, among which 15 types of proteins express up-regulation and 4 down-regulation. Comparative analysis on the 2-DE gel pictures of Naotaifang containing serum and Naotaifang containing plasma showed that 24 differential proteins of 5 plasma samples were identified, among which 9 types of proteins express up-regulation and 15 down-regulation. The highly expressed proteins were selected to MALDI-TOF-MS between Naotaifang containing serum and Naotaifang containing plasma. There were six successful-ly identified proteins, which were inter-alpha trypsin inhibitor, heavy chain 3, group-specific component, comple-ment factor B, Receptor Complexed with A Heterodimeric Fc, isoform CRA-d, Transferrin. It was concluded that protein with obvious changes in the Naotaifang containing serum and plasma may be related with fibrinolysis and an-ticoagulant. These proteins are involved in angiogenesis, inflammation and other pathological regulations of physiolog-ical processes. They are of great significance in the study of effective target and its signal transduction pathway of Naotaifang.
