This study aims to assess if adverse drug reactions (ADRs) to Kudiezi injection are allergic in origin. Hospital information system (HIS) data from 18 hospitals in China were used to carry out a nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving Kudiezi injection. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on solvents had a significant effect, P values were 0.005 5 and < 0.000 1 on suspected cases of allergic reactions. For the first subgroup analysis, we found using other eight injections at the same time as Kudiezi injection could be risk factors in suspected cases of allergic reactions. For the second subgroup analysis combining using mannitol or fructose could increase risks. Based on this current research, condition on admission as well as the concomitant use of some other drugs may be the risk factors in suspected cases of allergic reactions. However, further research for verification is required. This study can provide guidance for safe clinical practice in using Kudiezi injection.

AlM:To observe the changes of binocular vision in V-pattern exotropia children before and after surgical correction, and the effect of training in reconstructing the binocular vision after surgical corrections.METHODS: Sixty V-pattern exotropia children were enrolled in this study and were divided into three groups according to their age:group A (4~6 years old), group B (7~9 years old), and group C (10~12 years old), 20 cases for each group. Patients received routine refraction and ophthalmic examinations. Distance and near deviation were measured by prism-covering method and synoptophore. The simultaneous perception and fusion were examined with a synoptophore, and the stereacuity was measured with stereograms ( Titmus) . The children who didn’t reconstruct binocular vision function 1wk after surgery received binocular vision training. The data were recorded before and 1 , 2, 4, and 8wk after surgery. RESULTS: Binocular vision significantly improved among the children after surgery in group A and B ( P<0. 05 ) . Significantly divergence showed between group C and the other groups 1wk after surgery ( P < 0. 05 ). Binocular vision of the three groups all significantly improved 8wk after surgery, with no significant differences (P>0. 05). CONCLUSlON: V - pattern exotropia children can benefit from early surgical correction and training after surgery in reconstruct binocular vision.

Staphylococcus aureus ( S. aureus ) osteomyelitis, a significant complication for patients un-dergoing fracture fixation, is a great challenge for orthopaedic surgeons due to its extreme difficulty in mangae-ment. Animal models play an important role in exploring the pathogenesis of osteomyelitis and determining the efficacy of prophylactics and therapeutic treatment. To help understand current animal models of S. aureus os-teomyelitis, we conduct a systematic search to identify animal experiments that have investigated the management of S. aureus osteomyelitis. Experimental studies are categorized by animal species and are further classified by the setting of infection. Study methods are summarized and the advantages and disadvantages of each species and model are discussed.

Objective To investigate the effect of protein phosphatase 5 (PP5) on lipid metabolism in the PP5 knockout (KO) mice.Methods Male PP5 KO and wild type (WT) mice at the age of 6 weeks were used in this study. In order to study the effect of high fat diet ( HFD) feeding, the body weight was measured.The liver histology was examined by HE and oil red O staining.To further verify PP5 functions in the adipogenesis, in vitro experiment was carried out using mouse embryonic fibroblasts (MEF).Western blotting and real-time PCR were performed to quantified the expression of lipid metabolism-related genes in the liver tissues.Results Compared with the WT mice, the body weight gain was slower in the KO mice.The size of the lipid droplets was smaller and the quantity was less in the KO mouse liver tissue.In vitro study revealed that the KO mouse MEF cells showed less differentiated adipocytes with smaller lipid droplets than the WT MEF cells.This observation was further confirmed by detecting the expression of adipogenesis-related genes in the HFD liver.The markers of adipocyte differentiation, such as CD36, AP2, PPARγ2, and Glut4, were significantly decreased, while energy expenditure-related markers, such as phosphorylation of GR and expression of UCP1, were significantly increased.Conclusions Protein phosphatase 5 may play a regulatory role in the mouse lipid metabolism through regulating the de-phosphorylation of p-GR and enhancing the expression of UCP1.

Aim To observe the expression of epider-mal growth factor receptor ( EGFR) in cerebral tissues around hematomas after intracerebral hemorrhage, and explore the effects of EGFR on activation of astrocytes derived from rats and the involved mechanisms. Meth-ods The specimens of cerebral tissues around hemo-tomas after intracerebral hemorrhage undergoing hemo-tomas removal operation were collected and then divid-ed into 4 groups according to the time of intracerebral hemorrhage: <1 d, 1 ~5 d, 6 ~10 d and >10 d groups. Each group included 20 cases. At the same time, 20 dropped brain tissues distant to hemorrhage in the operative process were collected as control group. Immunohistostaining and Western blot were used to measure the expression of EGFR. After isolation and culturing, the astrocytes of rat cortex were treated with culture solution ( control group) , CNTF that was used to activate astrocytes, scramble siRNA + CNTF and EGFR siRNA +CNTF for 24h, respectively. The ex-pression of glial fibrillary acidic protein ( GFAP) mR-NA was detected through fluorescence real-time quanti-tative PCR. In addition, the protein levels of GFAP, signal transducers and activators of transcription 3 ( STAT3 ) and phosphorylated STAT3 ( p-STAT3 ) were examined using Western blot. Results With the ex-tension of intracerebral hemorrhage time, positive sig-nal index and protein expression levels of EGFR gradu-ally elevated, reached the peak on 6 ~10d, and then decreased after 10 d. There was statistical difference ( P<0. 01 ) . The expression levels of GFAP mRNA and protein as well as p-STAT3 were significantly in-creased in cells treated with CNTF alone as compared to control group ( P <0. 01 ) , whereas these effects were almost completely reversed by EGFR siRNA transfection ( P <0. 01 ) . Additionally, there was no statistical difference in STAT3 protein levels among groups ( P >0. 05 ) . Conclusions EGFR expression is upregulated in the cerebral tissues around hemotomas after intracerebral hemorrhage. Gene silence of EGFR contributes to suppressing the activation of astrocytes derived from rats, which may be involved in the block-ade of STAT3 phosphorylation.
