Objective To explore the functional impairment characteristics of acute stroke patients and cor- relate them to the functional independence after rehabilitation therapy. Methods Seventy-nine inpatients with stroke were divided into hemorrhage group and infarct group according to their condition.They are assessed by using measures of ESS,MBI,MMSE,Sheikh,Fugl-Meyer Balance and Fugl-Meyer motor assessment before rehabilitation treatment.After 1 month of treatment,all the patients were evaluated again using FIM.Correlation analysis was con- ducted with all the parameters. Results It was found that patients in the hemorrhage group scored lower with MBI, Sheikh,Fugl-Meyer Balance and FIM than those in the infarct group (P

Purpose To analyze the imaging manifestations of solitary fibrous tumors (SFT) so as to improve its diagnosis. Materials and Methods The CT and MRI findings of 24 patients with SFT confirmed pathologically were analyzed retrospectively and compared respectively with their pathological results in terms of lesion's location, size, shape, density (signal), type of enhancement and relationship with the surrounding tissues. Seven patients underwent MRI scan, 5 were with enhanced scan; 17 patients were carried out plain CT scan and 11 were with enhanced CT scan. Results The lesions in the 23 cases were solid and 1 was solid and cystic. Through the imaging diagnosis, 20 cases were diagnosed as benign tumors, 2 cases were diagnosed as malignancies, and 2 benign tumors were misdiagnosed, which showed that the diagnose accordance rate was 91.7%(22/24). On plain CT scans, 5 lesions (maximum diameter<4 cm) showed homogeneous density; 7 cases (maximum diameter>5 cm) showed heterogeneous density, 4 of which had calcification and 7 had necrosis; the shapes were round-like or lobulated. On enhanced CT scans, 5 cases presented progressive enhancement pattern, 5 cases showed fast-in and slow-out pattern, 1 case showed slight enhancement pattern. On MRI scan, 4 cases of the solid part of tumors showed isointensity signals on T1WI and isointensity or slight hyperintensity signals on T2WI, 3 cases showed isointensity or low signals on T1WI and low, isointensity or slight hyperintensity signals on T2WI, and slight hyperintensity signal on DWI, the solid part of tumors were strongly enhanced. Two malignant tumors presented features like heterogeneous density, unclear boundary, invasive growth and progressive enhancement pattern. The pathological findings demonstrated that the tumor tissues mainly consisted of spindle cells with rich fibers and vessels. Conclusion The imaging findings of benign and malignant SFT have certain features, malignant SFT have invasive growth signs. The obvious progressive enhancement of solid component which shows isointensity and hyperintensity on T1WI or T2WI may be helpful in the diagnosis of SFT; however, the final diagnosis should be confirmed with histopathology.

Objective To investigate the role of heme oxygenase-1 ( HO-1 ) and carbon monoxide ( CO) in children with mycoplasma pneumoniae infection. Methods A total of 198 cases with mycoplasma pneumoniae infection under 3 years were enrolled in this study. According to whether with wheezing,all cases were divided into wheezing group( n=58 ) and no wheezing group ( n=140 ) . According to having hypox-emia,wheezing group was divided into mild wheezing group(n=34) and severe wheezing group(n=24). And no wheezing group was set as control group. The serum COHb levels were measured by dual-wavelength spectrophotometry. The serum HO-1 were measured by ELISA. Results The levels of serum HO-1 and COHb% in severe wheezing group were ( 2 734. 10 ± 707. 59 ) ng/L, ( 3. 88 ± 0. 83 )%, and ( 1 130. 03 ± 671. 02) ng/L,(1. 16 ± 0. 63)% in mild wheezing group,and(931. 32 ± 451. 67) ng/L,(1. 04 ± 0. 37)% in no wheezing group,respectively. There were significant differences in serum HO-1 and COHb% between se-vere wheezing group and mild wheezing group(P<0. 01,respectively),and there were no significan differ-ences in serum HO-1 and COHb% between mild wheezing group and no wheezing group( P>0. 05,respec-tively). There was significant positive correlation between serum HO-1 and COHb%(r=0. 875,P<0. 01). Conclusion With mycoplasma pneumoniae infection,the expression of HO-1 and COHb% increase by the wheezing disease progression. HO-1 and CO may participate in the development process of infantile wheezing diseases.

OBJECTIVETo search for the optimal strategies for sperm collection from the patient with temporary penile erectile dysfunction (ED) on the day of oocyte pick-up ( OPU) in in vitro fertilization embryo transfer (IVF-ET).

METHODSWe retrospectively analyzed 93 cases of temporary ED on the OPU day of IVF-ET from January 2011 to May 2014, with fresh semen for 45 cases (group A), cryopreserved sperm before oocyte retrieval for 30 cases (group B), and frozen oocytes for 18 cases (group C). Group A was again subdivided into A1 (n = 18) and A2 n = 27) , the former intervened with oral sildenafil while the latter left untreated. We compared the rates of fertilization, high-quality embryo, and pregnancy among different groups.

RESULTSNo statistically significant differences were found among groups A, B and C in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and rates of cleavage, or in the percentages of normal fertilization (80.78% vs 80.43% vs 84.77%), high-quality embryo (53.27% vs 52.97% vs 47.69%) and pregnancy (60.00% vs 56.77% vs 44.44%) (all P > 0.05). The rate of 3PN was markedly lower in group C (0.63%) than in A (9. 61%) and B (4.34%) (P < 0.05). There were no significant differences between groups A1 and A2 in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and the rates of fertilization, cleavage, high-quality embryo, and pregnancy (all P > 0.05).

CONCLUSIONOn the OPU day of IVF-ET, oral sildenafil can help temporary ED men to achieve penile erection and ejaculation without affecting the outcomes of assisted reproduction. Cryopreserved sperm can be used in case of predicted temporary ED and frozen oocytes can also be employed if sperm retrieval fails. However, to avoid puncture injury to the epididymis or testis, fresh semen should be the first choice.

Background A multitude of studies reported statins prevent the myocardial hypertrophy induced by pressure overload,but the mechanism is unclear.Objective To study the protective effect of atorvastatin on the myocardial hypertrophy caused by pressure overload and it's anti-inflammation effect.Methods Forty Wistar rats were randomized to untreated group(n=10),atorvastatin group(2 mg/kg?d,by gavage,n=10),sham op- eration group(n=10)and control group(n=10).Ventricular hypertrophy model was achieved by surgical con- stricting the abdominal aorta.All rats were sacrificed 8 weeks after the operation and the heart weight to body ratio,left ventricular weight to body ratio,and the size of cardiomyocyte were determined.The expressions of interleukin 18(IL-18)and cardiotrophin 1(CT-1)in the cadiocyte were assessed by reverse transcription polymer- ase chain reaction(RT-PCR).Results Compared with control group,SBP in myocardial hypertrophy group was significantly increased(174?9 vs control 112?15 mmHg,P

Objective To investigate the effect of berberine on insulin resistance induced by free fatty acid in 3T3-L1 adipocytes and the possible molecular mechanism.Methods 3T3-L1 adipocytes were treated with 0.5 mmol/L palmitic acid to induce insulin resistance.Berberine was used for treatment and aspirin for positive control.Glucose oxidase method was employed for measuring the glucose consumption in the medium and 2-deoxy- [~3H]-D-glucose method was used for the determination of glucose uptake.Western blot was used for the determination of IKB kinase(IKK)?SerlS1 phosphorylation,insulin receptor substrance-1(IRS-1)Ser307 phosphorylation,the protein expression of IKK?,IRS-1,phosphatidylinositol 3-kinase(PI-3K)p85 and glucose transporter 4(Glut4).Results After the treatment with 0. 5 mmol/L of palmitic acid for 24 h,glucose consumption by 3T3-L1 adipocytes was decreased by 41%,insulin-stimulated glucose transport was inhibited by 67%,IRS-1 and PI-3K p85 proteins were reduced, and phosphorylations of IKK?Ser181 and IRS-1 Ser307 were induced.The above results were reversed by adding berberine or aspirin.But Glut4 and IKK?protein abundance was not changed during this study.Conclusion Berberine significantly improves insulin resistance induced by free fatty acid in 3T3-L1 adipocytes via inhibiting IKK?serine phosphorylation.

Introduction：Neonatal tetanus is a major cause of neonatal mortality in many developing countries and remains a major public health problem. This study aimed to determine risk factors associated with neonatal tetanus in Wenzhou, China.Methodology：Medical records of neonatal tetanus cases from 17 hospitals over a 13-year period (2000–2012) were reviewed for potential risk factors. Controls were selected from neonates with diseases other than tetanus who were admitted to the same facility during the same period. The potential risk factors of the neonatal tetanus group were compared with the control group using univariate analysis and an unconditional logistic regression model.Results：A total of 246 neonates with tetanus and 257 controls were included in this study. Univariate analysis showed that having untrained birth attendants, home delivery, an unsterile method of delivery and being a migrant to Wenzhou were significantly different between the two groups (P < 0.001). Logistic regression analysis revealed that the odds of having an untrained birth attendant, home delivery and an unsterile method of delivery were significantly higher in the tetanus group than the control group (odds ratio: 1371.0; 95% confidence interval: 206.0, 9123.5).Conclusion：This study identified that the main risks of neonatal tetanus in cases from Wenzhou were having an untrained birth attendant, home delivery and an unsterile method of delivery. Preventive measures directed to these risk factors may reduce the occurrence of neonatal tetanus in the studied area.

OBJECTIVETo establish a rabbit model bearing endometrial carcinoma and observe the magnetic resonance imaging (MRI) features of the metastatic lymph nodes.

METHODSVX(2) tumor grafts were orthotopically embedded into the endometrium of the rabbits. Three weeks after the implantation, the tumor and the metastatic retroperitoneal lymph nodes were examined with MRI, and the signal intensities and the size of the lymph nodes were compared with those in normal rabbits.

RESULTSOrthotopic tumor growth was observed in all the rabbits. Tumor infiltration of the serosa and retroperitoneal lymph node metastasis occurred 3 weeks after tumor implantation. MRI demonstrated obviously lymph node enlargement in the tumor-bearing rabbits as compared with those of normal rabbits, while the signal intensity of the lymph nodes were comparable between them.

CONCLUSIONThe endometrial carcinoma in this rabbit model well simulate the metastatic behavior of human endometrial carcinoma, and may serve as a good model for testing the efficacy of the contrast agents for MRI of the lymph nodes.

Objective To assess the value of 11 C-methionine (MET) PET/CT for the diagnosis of residual or recurrent glioma in comparison to 18 F-FDG PET/CT. Methods Forty-six patients suspected of residual or recurrent glioma underwent both 11 C-MET and 18 F-FDG PET/CT within 5-day interval. The glioma was considered as positive on PET/CT images based on ( 1 ) visual judgment of higher tracer uptake compared with the normal gray matter; (2) semiquantitative analysis of tumor to contralateral normal gray matter (T/G) and contralateral normal white matter (T/W) ratios. The diagnosis was confirmed by stereotsctic biopsy or radiological findings of MRI or CT and clinical follow-up ( ＞6 months). The Chi-square test and paired t test were used for statistical analysis. Results Residual or recurrent glioma was confirmed in 36 patients. The sensitivity, specificity, accuracy of 11C-MET and 18F-FDG PET/CT were 94.4% (34/36) vs 47.2% (17/36), 90.0% (9/10) vs 100% (10/10), 93.5% (43/46) va 58.7% (27/46) (x2 =19. 429, 1. 053, 15. 294, P ＜0.001, ＞0.05, ＜0.001 ), respectively. The T/G and T/W ratios of residual/recurrent giloma by 11 C-MET were significantly higher than those by 18 F-FDG (T/G ratio: 1.68 ± 0.23 vs 1.13 ±0.51, t = 5. 877, P ＜ 0. 001; T/W ratio: 2.52 ± 0.28 vs 1.42 ± 0. 57, t = 10. 470, P ＜0. 001 ). Conclusion 11 C-MET PET/CT is more sensitive and accurate than 18 F-FDG PET/CT for the detection of residual or recurrent glioma.
