Objective To study the effects of oxymatrine as inhibitor of hemorrhagic fever with renal syndrome virus (HFRSV) infection in vitro and in vivo.Methods In vitro studies,a dose of oxymatrine without cytotoxicity and 76-118 strain of HFRSV was taken to treat Vero cells in three ways:①After treated with oxymatrine for 48 h,Vero cells were attacked by HFRSV at dilution of 10-1 ～ 10-6,respectively for 24 h before changing to maintenance medium; ②Vero cells were first attacked by HFRSV of 10-1 ～ 10-6 dilution respectively,then oxymatrine was used for 48 h before changing to maintenance medium; ③Vero cells were attacked by HFRSV at dilution of 10-1 ～ 10-6 respectively,and meanwhile treated with oxymatrine for 48 h before changing to maintenance mcdium.Each dilution handled four porocytes,and four positive controls were set up at the same time.Indirect immunofluorescence assay (IFA) was performed to determine the inhibitory effect of oxymatrine in experimental group and positive control.In vivo studies,thirty 2-week-old hamsters,weighing about 30-40 g,were divided into experimental and control groups according to body weight,n =15.These aninals were inoculated intraperitoneally with HFRSV in 100TCID50(0.1 ml each); on days 4-13,0.1 ml of oxymatrine 1:100 were given to each hamster in experimental group daily by intraperitoneal injection,while the same amount of saline was given to the control ones.Lung tissue of hamsters was then dissected out to slice to be identified by immunofluorcscence stain.Results It was demonstrated that oxymatrine with the diluted fractions of 1:8 was safe in vitro.When the virus dilution of HFRSV was l0-4,compared with control groups,the differences were statistically significant in method 2 and 3 (z =-2.53,-2.53,all P ＜ 0.05),while no statistical significance in method 1 (z＝5.36,P＞ 0.05).When the virus dilution of HFRSV was 10-1 ～ 10-3,10-5,10-6,the differences were not statistically significant (z--0.00,-0.32,-0.19,4.21,4.21,all P ＞ 0.05).In vivo studies,compared with control group,the differences were statistically significant in experimental group (z =-3.85,P ＜ 0.05).Conclusion Oxymatrine significantly inhibites HFRSV.

This study aimed to explore the impact of depression caused by chronic unpredictable mild stress (CUMS) on in vivo activity of six kinds of CYP450 isoforms in rats. According to 'Katz' method, the model of CUMS was established. Tolbutamide, chlorzoxazone, theophylline, midazolam, omeprazole and dextromethorphan were chosen as probe substrates of CYP2C6, CYP2E1, CYP1A2, CYP3A2, CYP2D1 and CYP2D2 of rats. Plasma concentration of six kinds of CYP450 in control group and model group were determined by LC-MS/MS and computed pharmacokinetic parameters. Consequently, metabolism of theophylline and chlorzoxazone accelerated significantly (P < 0.01), but tolbutamide, dextromethorphan, omeprazole and midazolam had no significant difference. The present study proved that depression caused by CUMS had strong induction to CYP1A2 and medium induction to CYP2E1.

Objective To investigate whether elevated pre-procedural C-reactive protein (CRP) and Interleukin-6 (IL-6) concentrations may be relevant to early outcome in patients undergoing PCI.Method 100 consecutive patients undergoing pereutaneuous coronary intervention (PCI) were included in our study.Peripheral blood samples for CRP and IL-6 testing were withdrawn before PCI.Acute vascular complications resulted from PCI were determined by subsequently coronary angiography.The early coronary events during hospitalization were clinically followed.Results Thirty patients developed acute vessel occlusion,and another one developed subacute coronary thrombosis at 2 days after PCI.Increased levels of CRP correlated well with the occurrence of vascular complications as regards the significant difference existing amongⅠvsⅢandⅠvsⅣquartile groups,P

Objective To explore the epidemics of influenza viruses in Guangzhou area from 1998 to 2003. Methods The specimens for viral isolation were taken with swabs from children's throats and the material was inoculated into the MDCK cells and were incubated at 33 ℃ The supernatant of MDCK cells culture was tested with hemagglutination test. Results Influenza viruses were isolated from 264 of 3444 children; total positive rate of influenza virus isolation was 7.6%. The positive rate of influenza viruses was 16.8% in 1998; the prevailing strain of influenza viruses was H3N2. The influenza viruses isolation rate was 7.4% in 1999;the positive rate was 8.4% ; HIN1 occurred in 2000, the positive rate was 3.8%. H3N2 did not occur in 2001; the positive rate was 7.3% ; influenza B viruses was the prevailing strain in 2002; the positive rate was 1.7% in 2003. Influenza B viruses was Yamagata like strain from 1998 to 2001, Victoria like strain from 2002 to 2003. H9N2 avian influenza virus was isolated from a child. Conclusions Influenza was prevalent in Guangzhou in 1998, but not prevalent from 1999 to 2003. Most of influenza B viruses were Yamagata strain. There were cases avian influenza caused by H9N2 in 1999.

OBJECTIVETo develop the techniques of total hip arthroplasty(THA) for Crowe type IV developmental dysplasia of the hip (DDH) with S-ROM prosthesis,and to assess its clinical results.

METHODSFrom October 2000 to October 2011,30 patients (36 hips) with Crowe type IV DDH underwent THA,including 6 patients with bilateral hip involved and 24 patients with unilateral. S-ROM prosthesis was adopted together with subtrochanteric transverse osteotomy. All the cementless acetabular cups were placed at the original anatomic location. The threaded cups were put in or near the level of the true acetabulum in all patients. Full coating stems were used in femoral side. All the patients were evaluated by using the Modified Harris Hip Score. Radiographic evaluations were made preoperatively and during follow-up.

RESULTSTwo patients lost of follow-up. Twenty-seven patients with 32 hips were followed up,and the average duration was 48 months (ranging from 7 to 84 months). There was 1 patient with bilateral THA died from hemorrhagic shock. Two patients could walk freely with the visible fracture lines at 12th and 18th months postoperatively. There were no complications such as infection or nerve injuries. Modified Harris Hip Score improved from preoperative 41.7+/-3.7 to postoperative 89.1+/-2.9. There was no acetabular or femoral component revision because of mal-position or loosening of the prostheses in all patients. Postoperative X-ray showed that all the prostheses in place,good integration between acetabular cups,femoral prosthesis and host bone without loosening. All bone grafts were integrated. All the hips acquired union of osteotomy and bone in-growth. None of the patients had radiographic evidence of aseptic loosening of prosthesis.

CONCLUSIONFor the complex DDH, follow methods should be used to improve therapeutic effects:good exposure of the true acetabulum,deepen acetabulum, femoral shortening, oblique osteotomy, using the S-ROM prosthesis.

Objective To observe the protective effects of a mixture for protecting liver and supplementing stomach (保肝益胃合剂) on rat acute liver damage induced by carbon tetrachloride (CCl_4). Methods The model of rat acute liver damage was established by injection of CCl_4 2 ml/kg into the abdominal cavity.The rat models were treated respectively by the mixture for protecting liver and supplementing stomach 30 g?kg~(-1)?d~(-1),the polyene phosphatide acid radical choline capsule [Yi Shanfu (易善复), 180 mg?kg~(-1)?d~(-1)],the glycyrrhizic acid diaminogen capsule [Gan Lixin (甘利欣),30 mg?kg~(-1)?d~(-1)] infused into the stomach.The activities of serum alanine transaminase (ALT) and aspartate transaminase (AST) were detected.In the mean time,the liver pathological changes were observed,the degree of liver cell necrosis was evaluated,and the rat mortality was noted in various groups of treatment.Results The values of ALT,AST and the score of liver cell necrosis in the group treated with the mixture for protecting liver and supplementing stomach [(1.168?1.066) kU/L,(1.845?2.212) kU/L,(0.56?0.53) score] were significantly lower than those in the model group [(4.982?3.502) kU/L,(7.030?3.616) kU/L, (1.38?0.92) scores],and all the differences being statistically significant (all P

Objective To investigate the relationship between the driver genes mutation and the survival in patients with pulmonary adenocarcinoma brain metastasis. Methods We enrolled 200 patients with pulmonary adenocarcinoma brain metastasis confirmed histologically from Jan 2013 to Dec 2015, and tested EGFR, KRAS, ALK, Her-2 gene mutation, analyzed the relationship between EGFR gene mutation and clinicopathological data and prognosis of the patients.Results The mutation rates of EGFR, KRAS, ALK and Her-2 gene mutation were 48.5％, 5.5％, 6.5％, 3.5％, respectively. Compared with EGFR gene mutation patients, the sex, age, BMI, differentiation were significant different (P＜0.05), however, the smoking was not significant different (P＞0.05). Patients with EGFR gene mutation who received targeted therapy survived longer than who did not receive targeted therapy, (28.0 ±4.5) months vs (11.2 ±1.4) months. By Log Rank (Mantel-Cox), the median survival time between the two groups was statistically significant (P＜0.05).Conclusions The mutation rate of EGFR gene mutation was high in patients with pulmonary adenocarcinoma brain metastasis, and the patients will survivel longer by targeted therapy.

Objective To analyze the magnetic resonance imaging (MRI) features of spinal epidural angiolipoma to improve the diagnostic accuracy of this tumor. Methods The MRI findings in 2 patients with histopathologically confirmed spinal extradural angiolipoma were analyzed retrospectively. Results In both of the cases, the tumors were located in the extradural space of the thoracic intraspinal canal. The spindle-shaped tumor mass extended parallel to the longitudinal axis of the spine. The lesions presented with fat and vascular signal features. One of the tumors grew through the intervertebral foramen with a dumbbell appearance, invading the adjacent diaphragma, vertebral body, pedicle of the vertebral arch and the spinous process. The other tumor consisted of some tortuous and dilated blood vessels with flow void signals. Conclusion Spinal epidural angiolipoma presents characteristic features on MRI, which is considered the best diagnostic modality for this tumor.
