Objective To observe the effects of psychological supportive therapy on the activities of daily living (ADL) and depression after cerebral hemorrhage. Methods 60 cases with mild or medium depression according to 17 items Hamilton Rating Scale for Depression (HAMD-17) after cerebral hemorrhage were divided into treatment group (n=30) and control group (n=30). All of them accepted physical exercise, and those in the treatment group accepted psychological supportive therapy in addition. They were assessed with Functional Independence Measure (FIM) and HAMD-17 before and after the treatment. Results After 2 months of treatment, the score of FIM increased more in the treatment group than in the control group (P<0.001), and the score of HAMD-17 decreased (P<0.001). Conclusion Psychological supportive therapy may promote the recovery of ADL and depression for patients post cerebral hemorrhage.

In order to obtain higher L-lactic acid yield industrial strain, the original strain Rhizopus oryzae PW352 was mutated by means of N+ ions implantation and a mutant strain Rhizopus oryzae RE3303 was obtained. Its lactic acid yield was increased by 75% than that of the original one. The acid producing condition was optimized by orthogonal design. The concentration of L-lactic acid reached to 131～136g/L and the conversion rate of glucose was as high as 86%～90% under the optimum condition.

Objective To explore the effects of action observation therapy on upper-extremity motor function after ischemic stroke and on the motor cortex using functional magnetic resonance imaging (fMRI).Methods Forty patients with ischemic stroke were randomly assigned to an observational group (n =20) or a control group (n =20).Both groups received conventional rehabilitation,while the observational group was additionally provided with action observation therapy for 8 weeks.Both groups were assessed using the Fugl-Meyer assessment (FMA) and the Barthel index (BI) before and after the 8 weeks of treatment and functional magnetic resonance imaging was performed before treatment.Two months after the treatment,nine patients of the experimental group and 8 of the control group who continued to receive their respective treatments after discharge were again assessed using functional magnetic resonance imaging.Results After the treatment the average FMA score and BI score of both the observational group and the control group had increased significantly.The increase in the average FMA score of the observational group was significantly greater than that of the control group.However,there was no significant difference between the two groups in the increases in BI score after 8 weeks of treatment.The fMRI results showed that there was a significantly greater rise in activity in the bilateral precentral gyrus,parietal lobe and the supplementary motor area of the patients in the observational group after the treatment compared with the control group.Conclusion Action observation therapy can improve upper extremity motor function and performance in the activities of daily living after ischemic stroke and induce changes in the excitability of the cerebral motor cortex.

Objective To explore the effects of action observation therapy on upper-extremity motor function and ability in the activities of daily living after cerebral infarction.Methods Forty-one cerebral infarction survivors were randomly assigned to an observation group (n =21) or a control group (n =20).Both groups were given the conventional rehabilitation treatment,while the observation group additionally received action observation therapy 20 mins per day,6 times per week for 8 weeks.Before and after the 8 weeks of treatment,both groups were assessed using the Fugl-Meyer assessment (FMA),Wolf's motor function test (WMFT) and the modified Barthel index (MBI).Results Before the intervention there was no significant difference between the groups in any of the measurements.After the 8 weeks of treatment,all of the results in the treatment group were significantly better,on average,than those of the control group.Conclusions Action observation therapy can improve upper-extremity motor function and ability in the activities of daily living after stroke.

OBJECTIVETo investigate the occult lymph node metastasis in the middle and lower third rectal cancer after neoadjuvant radiotherapy.

METHODSFrom June 2003 to December 2006, 74 rectal cancer patients received neoadjuvant radiotherapy (30 Gy/10 f/2 w, CACA-CRC-001) and underwent total mesorectal excision (TME) two weeks later. Fat clearance technique was used in all the samples. Occult lymph node metastasis was detected in the mesorectum using the anti-CK antibody.

RESULTSIn total 1883 retrieved lymph nodes, 172 metastasis lymph nodes were harvested by HE examination with the mean diameter [(4.9+/-2.6) mm] being larger than that (2.7+/-1.4) mm of the 1711 negative nodes (P<0.01). In HE negative nodes, occult metastasis was found in 40 lymph nodes (2.33%) from 24 patients. Most of these nodes were less than 5 mm (90.0%) with a mean diameter of (3.2+/-1.2)mm, smaller than those of HE-positive metastasis nodes (P<0.01). Occult metastasis was found in 23.1% (9/39) of HE-negative patients. Occult metastasis incidence was higher in patients with HE-positive nodes (42.8%,P<0.01). No correlation of lymph node occult metastasis with tumor differentiation, age, or surgical procedures was found. There was no significant difference in recurrence-free survival between ypN(0) patients with and without occult metastasis (P=0.157).

CONCLUSIONIt is not necessary to include occult lymph node metastasis in the TNM staging in patients with ypN(0) rectal cancer.

Objective To explore whether the degree of 99Tcm-methoxyisobutylisonitrile (MIBI) uptake in non-small cell lung cancer (NSCLC) could be correlated with the treatment response to three-dimensional conformal radiotherapy.Methods A total of 102 patients with NSCLC were studied with 99Tcm-MIBI SPECT before radiotherapy.The patients were classified by a follow-up CT as responders (complete or partial remission) and non-responders (stable or progressive disease).After intravenous administration of 740 MBq 99Tcm-MIBI, SPECT imaging at 10-30 min (early) and 2-3 h (delayed) were performed.Region of interest (ROI) was placed over the tumors and contralateral normal lung tissue.The uptake ratio of tumor to contralateral normal lung (T/N) was obtained from both early (ER) and delayed (DR) SPECT images.The retention index (RI) was measured as:RI = (DR - ER)/ER×100%.Statistical analysis was performed by two independent-sample t-test and Mann-Whitney U test using software SPSS 13.0.Results 99Tcm-MIBI uptake was significantly higher in responders than in non-responders:2.36 ±0.17 vs 1.82 ±0.14 (ER) and 2.48 ± 0.20 vs 1.94 ± 0.16 (DR), respectively (t = - 13.1,- 12.7, both P＜ 0.05).The median RI in the responders group was also significantly higher than that in the non-responders group (6.60% vs 5.13%, z = - 6.83, P ＜ 0.05).Conclusion ER, DR and RI of 99Tcm-MIBI SPECT might be useful to estimate the treatment response to three-dimensional conformal radiotherapy in patients with NSCLC.

OBJECTIVECT120B gene is a splicing variant of CT120A, which deletes 96 nucleotides and leads to an in-frame loss of 32 amino acids between the codon 136 and 167 as compared with CT120A. This study was undertaken to assess the effects of CT120B expression on lung cancer cell growth and to explore the gene expression profiles.

METHODSCT120B cDNA was transfected into the human lung adenocarcinoma SPC-A-1 cells, and stable cell lines overexpressing CT120B were established. CCK-8 assay and tumorigenecity in a xenograft model were performed to analyze cell proliferation in vitro and in vivo. The differential gene expression induced by overexpressed CT120B was investigated using Atlas cDNA expression array. Flow cytometry was performed to analyze cell cycle and cell apoptosis.

RESULTSOverexpression of CT120B in SPC-A-1 cells resulted in a reduced cell growth rate in vitro, and decrease of the tumorigenicity in nude mice. A total of 38 genes were identified as differential expressions with more than a 2.0-fold change by Atlas cDNA expression array analysis, including downregulated cyclin E1, cdk 2, c-kit, CXCR4 and upregulated caspase 8 gene. Overexpression of CT120B also induced G1 phase arrest, but had no effect on cell apoptosis.

CONCLUSIONThe G1 cell cycle arrest, but not apoptosis, underlay the growth inhibitory activities of CT120B. The down-regulation of c-kit and CXCR4 expression might also contribute to the suppressive effects on cell growth of CT120B.

OBJECTIVETo evaluate the safety and efficacy of hand-assisted laparoscopic surgery (HALS) in colorectal tumors.

METHODSClinical data of 70 patients with colorectal tumors were retrospectively analyzed. All the patients had received HALS colectomy in the Beijing Cancer Hospital. Lapdisc was used for the hand port at the umbilicus. Two additional trocars were used.

RESULTSThere were 38 males and 32 females. The median age was 61(29-89) years. Diagnoses included sigmoid cancer(n=48), sigmoid adenoma(n=4), descending colon cancer (n=3), ascending colon cancer (n=1), rectal cancer (n=13), total colectomy(n=1). The operative time was (126.0±22.5) minutes. The intraoperative blood loss was (75.0±18.8) ml. The mean number of lymph node dissection was(16.8±4.2). The median postoperative hospital stay was 9.4 days. There were no perioperative deaths. One patient developed anastomotic stricture and two anastomotic leak, all of which were successfully managed with conservative treatment.

CONCLUSIONHALS is a safe and effective technique for colectomy.

OBJECTIVETo evaluate the agreement and correlation between hepatic vein pressure gradient (HVPG) and portal vein pressure (PVP) in patients with portal hypertension,and explore their clinical value.

METHODSA total of 46 patients with portal hypertension were directly measured the free hepatic pressure, wedged hepatic pressure, portal vein pressure before and after TIPS therapy. The agreement and correlation of HVPG and PVP were analyzed, and explore their clinical value.

RESULTSThere is no significant agreement or correlation between HVPG and PVP in 5 patients, whose third hilar have large communicating branches between portal vein and Inferior vena cava, or with obvious umbilical vein opened. The HVPGs were significantly agreed with portal vein pressure in other 41 patients. There is no significant difference of HVPG or PVP between earlyTIPS and not early-TIPS groups. In addition, the portal vein pressures after TIPS were significantly decreased compared with that before TIPS.

CONCLUSIONThe HVPG can well show the PVP except these with obvious communicating branches between portal vein and Inferior vena cava in third hilar, and TIPS can effectively decrease the portal vein pressure in patients with portal hypertension.
