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

The expression of paired immunoglobulin-like receptor B (PirB) in normal and injured spinal cord of rats was investigated. The SD rat hemi-sectioned spinal cord injury (SCI) model was established. Before and 1, 3, 7, 10 days after SCI, the spinal cord tissues were harvested, and Western blot and immunohistochemistry were used to examine the expression and location of PirB. The results showed that the expression level of PirB in the normal spinal cord of SD rats was low. At the first day after SCI, the expression of PirB was obviously increased, and that in the injured spinal cord from the first day to the 10th day was significantly higher than in the normal spinal cord. The positive expression of PirB in neurons from different regions of gray matter of the injured spinal cord was seen. It was concluded that the expression of PirB in the normal spinal cord of rats was low. The expression of PirB in SCI was significantly increased till at least the 10th day.

Objective To explore the influence of MYC expression level on ovarian cancer cells adhesion and invasion ability,and the involvement of the integrinβ1 in the adhesion and invasion control. Methods Comparative study was done to analyze the relationship between the mRNA level of MYC and ITGB1 among sixty cell lines from the NCI-60 cells bank; Western blot was performed to demonstrate the correlation of MYC and ITGB1 protein level in ovarian cancer cell lines;Immunohistochemistry was adopted to compare the expression level of MYC and ITGB1 in paired primary and metastatic ovarian cancer tissue. Furthermore ,we employed in vitro adhesion test to detect the alteration of ovarian cancer cell adhesion ability to ECM molecular like fibronectin ,collagen I and laminin after fluctuation of MYC and ITGB1 expression; Transwell assay was applied to check the invasion ability variation with the disturbance of MYC and ITGB1 level. Results The mRNA levels of MYC and ITGB1 were dramatically inverse-correlated in NCI-60 cells bank(P<0.01);The protein levels of MYC and ITGB1 in ovarian cancer cell lines were also negative correlated; The primary ovarian cancer tissue showed lower expression of ITGB1 and higher expression of MYC,while the matched metastasis displayed the opposite outcome;Ovarian cancer cells reduced adhesive and invasive capacity in case of ITGB1 being down-regulated ,however, the adhesive and metastatic ability improved tremendously with elevation of ITGB1;Promoted adhesion and invasion ability and rise of ITGB1 expression were observed after downregulation of MYC,meanwhile,and inhibition of ITGB1 reversed the increasement of adhesion and invasion ability. Conclusions MYC,inversely-correlated with ITGB1 in ovarian cancer cells,inhibited ovarian cancer cells adhesion and invasion. Inhibition of MYC could lead to enhanced adhesion and invasion ability of ovarian cancer cells.

Objective studyring the proven and probable invasive pulmonary aspergillosis(IPA) eases of some hospitals in Shanghai to provide evidence fur the improvement of IPA clinical diagnosis and therapy.Methotis Fortv-nine IPA cases were retrospectively analyzed for demography data,host tactors,underlying conditions.chest CT,microorganism and histopathology examination,as well as therapy and clinical outcome.ResultsOf 49 subjects including 19(38.8%)proven and 30(61.2%)probable IPA,3 pailents(6.1%)had no host factors,25 patients(51.0%)had IPA associated host factors and underlying conditions.while 21 patients(42.9%)had uncertained fundamental diseases.Chest CT evaluation demonstrated that radiological lesions include nodules in 29 patients,patching in 15,mass in 12,consolidation in 10.cavitation in 34,Halo sign in 19,air bronchogram in 18,crescentic sign in 6,bilateral in 33 and multifocal lesions in 38.The yielding rate of fungus culture in sputum was 26.5%(13/49),and in bronchoalveolar lavage fluid was 66.7%(10/15).Eleven of thirty-six patients(30.6%)had positive results of serum galactomannan antigen tests.Nineteen of twenty-one patients(90.5%)were proven as IPA by lung histologic examinations.Aspergillus fumigatus was the most common pathogen 81.0%(17/21).The responding rate to initial anti-fugus therapy wag 50%(21/42).Conclusion Our study suggests that in IPA patients,bilateral,muhifocal and nodular lesion could be the most common radiological characteristic,while Halo and crescentic sign occar occasionally.Invasive technologies are more valuable to IPA diagnosis.

OBJECTIVELeptin (LEP) is mainly produced by white adipose tissue and participates in the energy metabolism and regulation of growth. Cooperating with the other metabolic hormones, it plays an important role in the developments of fetus and neonates. This study was designed to test the serum levels of LEP, neuropeptide Y (NPY), insulin (INS) and insulin-like growth factor-1 (IGF-1) and measure the body mass index (BMI) and head circumference (HC) at different days of life of premature infants with or without serious diseases and to find the changes of serum levels of LEP as well as NPY, INS and IGF-1, the relationship between those hormones and the changes of body weight and the influences of diseases on the levels of those hormones in premature infants.

METHODThe clinical data as well as weights, lengths, HC of 40 sick premature infants (sick group) and 30 premature infants without any diseases (control group) were collected and the serum levels of LEP, NPY, INS and IGF-1 were determined by using radioimmunoassay (RIA) at d 1, d 7 and d 12 of life. BMI was calculated by weight (kg)/length (m)(2). SPSS13.0 was used to analyze the data

RESULT(1) In sick group the serum LEP levels were 0.74 +/- 0.21, 0.60 +/- 0.18, 0.82 +/- 0.12 (mg/L) (P < 0.01), the BMI were 9.81 +/- 1.24, 8.36 +/- 0.87, 9.08 +/- 1.12 (kg/m(2)) (P < 0.01) on d 1, d 7 and d 12, respectively. In control group serum LEP levels were 0.78 +/- 0.17, 0.71 +/- 0.17, 0.88 +/- 0.58 (mg/L) (P < 0.01), the BMI were 10.03 +/- 1.04, 9.35 +/- 0.80, 11.06 +/- 0.82 (kg/m(2)), on d 1, d 7 and d 12, respectively (P < 0.01). In both groups, serum LEP levels as well as the BMI decreased on d 7 and reincreased on d 12. The differences of serum LEP levels and BMI between sick group and control group at d1 were not significant (P > 0.05); compared with control group, the serum LEP levels and BMI on d 7 and d 12 in sick group were lower and the differences were significant. (2) There were positive correlations between serum LEP levels and BMI in sick group as well as in control group. (3) In sick group, the serum NPY levels at d 1, d 7, d 12 were 55.33 +/- 9.38, 46.64 +/- 6.17, 75.13 +/- 9.12 (ng/L) (P < 0.01), INS were 10.07 +/- 2.63, 7.71 +/- 2.77, 10.37 +/- 2.29 (mU/L) (P < 0.01), IGF-1 were 38.66 +/- 11.42, 31.98 +/- 7.34, 41.84 +/- 8.05 (mg/L) (P < 0.01), respectively. In control group, the serum NPY levels at d1, d 7 and d 12 were 57.77 +/- 7.15, 48.49 +/- 8.81, 81.36 +/- 8.51 (ng/L) (P < 0.01), INS were 11.55 +/- 1.99, 8.28 +/- 2.87, 15.42 +/- 3.80 (mU/L) (P < 0.01), IGF-1 were 37.76 +/- 7.07, 34.33 +/- 8.97, 50.19 +/- 8.38 (mg/L) (P < 0.01), respectively. In both groups, serum levels of NPY, INS and IGF-1 had positive correlations with serum LEP levels as well as BMI on the corresponding days and decreased on d 7 and reincreased on d 12.

CONCLUSION(1) The serum LEP levels decreased on 7 d of life and reincreased on 12 d of life, which corresponded to the changes of the physical development of premature infants. (2) The serum LEP levels in sick premature infants decreased definitely as compared with control group, which suggested that diseases had negative influences on the LEP levels and the physical developments were slowed down in sick premature infants. (3) The serum levels of NPY, INS and IGF-1 had positive correlations with LEP levels as well as BMI at the early period of life, which suggested that NPY, INS and IGF-1, cooperating with LEP, might take part in the regulation of development of premature infants.

Objective To analyze the choice of implant materials,key points of operative proce- dures,prevention and management of postoperative complications in patients treated with cranioplasty. Methods Two hundred and twenty six patients with craniocerebral trauma underwent cranioplasty with different implant materials.Attention should be paid for the purpose of not tearing or injuring the dura ma- ter during operation.To take the dura mater up to the implant material and the edge of the bone flap,and put drainage under the scalp flap before closure of the incision.Results The clinical symptoms and neural function were improved in 146(64.6%)patients postoperatively.Postoperative complications mainly were infection,fluid collection and hematoma in the operative region.Follow-up showed the occur- rence of displacement or collapse of the implant materials in some patients.Conclusion Timely cra- nioplasty can not only resolve cosmetic problems but also improve clinical symptoms and neural function. The causes of postoperative complications are mainly related with the operative procedures and the materi- als used.

Illegally paid blood donation was a risk factor for HIV acquisition exclusively in Henan and Hubei Provinces of China, and not in Shanghai. Nucleotide sequences in the gag and env genes of HIV-1 were compared between isolates from Henan and Shanghai regions of China to test whether an expected higher degree of a common source of infections from this unique blood donation transmission risk would be evident as decreased variation among Henan isolates in an exploratory cross-sectional analysis. Among 38 isolates studied, 23 of 23 (100%) from Henan and 8 of 15 (54%) from Shanghai were subtype B. In addition, fewer sequence differences were found in gp41 of subtype B isolates from Henan than from Shanghai isolates. Further studies with additional controls are therefore warranted to confirm the role of the degree of a common source of infections in differences in HIV variation across populations.

The expression of paired immunoglobulin-like receptor B(PirB)in normal and injured spinal cord of rats was investigated.The SD rat hemi-sectioned spinal cord injury(SCI)model was established.Before and 1,3,7,10 days after SCI,the spinal cord tissues were harvested,and Western blot and immunohistochemistry were used to examine the expression and location of PirB.The results showed that the expression level of PirB in the normal spinal cord of SD rats was low.At the first day after SCI,the expression of PirB was obviously increased,and that in the injured spinal cord from the first day to the 10th day was significantly higher than in the normal spinal cord.The positive expression of PirB in neurons from different regions of gray matter of the injured spinal cord was seen.It was concluded that the expression of PirB in the normal spinal cord of rats was low.The expression of PirB in SCI was significantly increased till at least the 10th day.

Objective To investigate and evaluate the technique of microsurgery,for the treatment of the large and huge meningiomas of the sphenoid wing. Methods Fifty-eight patients were finally diagnosed by CT and/or MR in this series. The sphenoid wing meningiomas were from 4 cm×3.5 cm×3.5 cm to 11 cm×10 cm×8 cm in volume,and were located at outside sphenoid wing in 28 and at the inner in 30,and were spherical in 53 and en plaque in 5.The microsurgery for resection of the tumors was done through a cranio-orbito-zygomatic or craniozygomatic approach in 10, and through a modified pterional approach in 48.Results Total resection was achieved in 52.No death occurred in the group.Follow-up of 6 months to 9.5 years showed obvious nervous function impmvement in 49 and regrowth of the tumor in 8. Conclusions Based on the volume and development of the tumor,it is very imprtant for improving merapeutic Outcome to choose appropriate operative approach, get rid of the tumor piece by piece,and protect the nerves and vessels intraoperatively.

OBJECTIVETo investigate the correlation between different Chinese medicine (CM) syndromes and variations in microcirculation in septic shock patients.

METHODSseventy Septic shock patients were divided into four groups: heat damaging qi-yin group (HDQY, 23 cases); yin exhaustion and yang collapse group (YEYC, 26 cases); excessive heat in Fu organ group (EHFO, 10 cases); and heat damaging nutrient-blood group (HDNB, 11 cases). Sublingual microcirculation parameters were observed by sidestream dark-field (SDF) imaging and scored by Acute Physiology and Chronic Health Evaluation II (APACHE II) and the Sequential Organ Failure Assessment (SOFA), and parameters of microcirculation perfusion variations and prognoses were analyzed.

RESULTSCompared with those with qi-yin heat damage, perfused vessel density (PVD) in other groups decreased dramatically (P<0.05), and APACHE II scores increased significantly (P<0.05). In addition, the recovery time was prolonged substantially (P<0.05), and the mixed venous oxygen saturation (SVO2) decreased (P<0.05). Blood lactic acid increased significantly (P<0.05), and the mixed SVO decreased (P<0.05), in the YEYC group. Compared with the thermal injury camp blood group, sublingual microcirculation parameter variations showed no obvious difference in the YEYC and EHFO groups (P>0.05). There were significant positive correlations between CM syndromes and APACHE II scoring in different groups (r=0.512, P<0.05). There were negative correlations between PVD and APACHE II scoring (r=-0.378, P=0.043), the proportion of perfused vessels (PPV) and APACHE II scoring (r=-0.472, P=0.008), as well as between the microvascular flow index (MFI) and APACHE II scoring (r=-0.424, P=0.023) in different patients.

CONCLUSIONSublingual microcirculation may serve as a clinical diagnostic parameter of the patient condition, as well as being a prognostic indicator.
