To analysis effects of rehabilitation and improvement of ADL in post-stroke patients, 114 cases were divided into two groups A and B. Rehabilitation treatment started for the patients in group A in two or three months after onset of the stroke, while group B in four or six months. The ADL of 114 cases were evaluated before rehabilitation and one month after rehabilitation. Treatment was siginificant in both groups (P<0.001). The improvement of ADL in group A was better than group B in grooming, feeding, dressing, toilet, utensil using, moving on the bed, locomotion and walking (P<0.05). Rehabilitation treatment is favorable for improving ADL ability of post-stroke patients. The earlier rehabilitation treatment starts, the better improvement of ADL is.

Objective To evaluate the diagnostic value of endoscopic miniprobe ultrasonography (MPS) and endoscopic therapies under the guidance of MPS in gastrointestinal submucosal tumors. Methods Patients with submucosal tumors of lower digestive tract were given MPS under colonoscope. Endoscopic therapy or surgery had been taken according to different deriving layers of submucosal tumors. The ultimate diagnosis was confirmed by histology. Results Twenty patients with submucosal tumors were diagnosed with MPS under colonoscope, including 9 patients with stromal tumors, 5 patients with lipoma, 3 patients with car-cinoid, 2 patients with abscess,1 patient with intestines pneumatosis. Four patients with benign stromal tumors derived from muscularis mueosa and 2 patients with carcinoid were resected by endoscopy. Two patients with abscess and 1 patient with intestines pneumatosis were puncture under endoscopy. Three patients with benign stromal tumors from muscularis propria, 2 patients with malignant stromal tumors, 2 patients with lipama and 1 patient with careinoid were resected surgically. 88.24% submucosal tumors diagnosed by MPS were identified by pathology. Three cases were followed-up by endoscopy. Conclusions Different layers of gastrointestinal tract with submucosal tumors can be distinguished clearly by MPS leading to definite diagnosis of submucesal tumors. MPS can play an important role in selecting treatment procedures.

Objective To explore the type of circadian rhythms and risk factors for post-stroke insomnia. Methods From January, 2012 to June, 2014, the patients with cerebral middle artery infarction were divided into insomnia group (n=25) and control group (n=25). The general characterizations of the patients were collected. They were assessed with Morning and Evening Questionnaire (MEQ), Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS) and Fatigue Severity Scale (FSS). Results The MEQ score was lower in the insomnia group than in the control group (t=2.676, P<0.05). The frequency of moderate night type (20%) and absoluteness night type (4%) were higher in the insomnia group than in the control group. High score (>11) of National Institutes of Health Stroke Scale (NIHSS) was the independent risk foctor for post- stroke insomnia (OR=1.463, 95% CI=1.112- 1.925). The scores of ESS, PSQI, ISI and FSS were higher in the insomnia group than in the control group (t>5.609, P<0.001). The scores of ESS (r=0.334, P<0.05), FSS (r=0.535, P<0.01), PSQI (r=0.461, P=0.001) and ISI (r=0.504, P<0.01) were positively correlated with the NIHSS score. Conclusion The patients with post-stroke insomnia impair in circadian rhythms. High NIHSS score is the independent risk factor for post-stroke insom-nia.

Plant active components characterized of many different structures and activities on multiple targets, have made them to be the important sources of inhibitors on HIV-1. For finding leading compounds with new structure against HIV-1, three key HIV-1 replicative enzymes (reverse transcriptase, protease and integrase) were used as screening models. The in vitro activities of 45 plant derived components isolated from Schisandraceae, Rutaceae and Ranunculaceae were reported. Within twelve triterpene components isolated, eight compounds were found to inhibit HIV-1 protease, in these eight active compounds, kadsuranic acid A (7) and nigranoic acid (8), inhibited both HIV-1 protease and integrase; Among fifteen lignans, meso-dihydroguaiaretic acid (15) and kadsurarin (16) were active on HIV-1 reverse transcriptase, and 4, 4-di(4-hydroxy-3-methoxyphenly)-2, 3-dimethylbutanol (13) active on HIV-1 integrase. All of the six alkaloids, seven flavones, and five others compounds were not active or only with low activities against HIV-1 replicative enzymes. Further studies of the triterpene components showing strong inhibitory activities on HIV-1 were warranted.

Objective To explore the risk factors of shoulder-hand syndrome after first onset of the stroke. Method The likely related factors of the post-stroke shoulder-hand syndrome of 103 patients who suffer from stroke within first 3 months during January 2001 to April 2003 were regressively analyzed. Results The incidence of the post-stroke shoulder-hand syndrome is about 30.1%. The results showed that shoulder subluxtion and age are two independent risk factors. Conclusion Shoulder-hand syndrome is a common complication occurring within 3 months after stroke. It is nesessary for clinicians to pay more attentions to these factors and to take preventive procedure at early stage in order to reduce the incidence as much as possible.

We measured IgG and IgM ACA levels by a modified enzyme一linked immunosorbent as-say(ELISA) in 122 patients with brain infarction and 86 healthy controls. Significant difference in positiveIgG and IgM ACAs was found between the patients with infarction(50.8%)and the control group(11.6%).The relation between positive ACAs and brain infarction was studied. The pathogenetic mecha-nism remains unclear.

Objective To investigate the role of Huang-qi in balance of TH1/TH2 in asthma on dendritic cells level. Methods DCs from human peripheral blood mononuclear cells(PBMC) were induced by rhGM-CSF and rhIL-4, and then were identified. The level of IL-12 and IL-10 produced by DCs were de-tected by ELISA assay. After autoreactive T cells, mRNA of T-bet and GATA-3 was measured by RT-PCR. Simultaneously, IL-4 and IFN-γ were determined by flow cytometer. Results After 7 days culture, IL-12 was significantly decreased in asthma group compared to control group (P ＜ 0.01), whereas IL-10 on the opposite. At the 7th day of co-culture with T cells derived from floating cells, the IFN-γ/and T-bet mRNA level in asthma group were significantly decreased than that in control group, whereas IL-4, GATA-3 mRNA level, the ratio of IL-4/IFN-γ and GATA-3/T-bet were apparently increased in asthma group than that in control group(P＜0.01). After Huang-qi treatment, the IFN-γ/and T-bet mRNA level were significantly in-creased, whereas the ratio of IL-4/IFN-γ and GATA-3/T-bet, and the IL-10 level were apparently de-creased, but the level of IL-12, IL-4 and GATA-3 mRNA were not changed significantly. Conclusion DCs in asthma regulated the balance of TH1/TH2 by means of secreting decreased IL-12 and increased IL-10, that made TH2 playing a dominance role which is the key factor in initiating asthma. Huang-qi regulated DCs through decreasing the level of IL-10, and thus decreased the ability of inhibiting the differentiation of TH1 from TH0, that is also inhibiting the differentiation of TH2 from TH0 directly.

The positive expression rates of MMP-2, Cyr61 and CD25 in esophageal carcinoma group in different T stage, N stage and M stage all had statisticall differences (P ＜ 0.05),while there was no significant difference in different degree of differentiation (P ＞ 0.05 ). ConclusionMMP-2,Cyr61 and CD25 is highly expressed in esophageal carcinoma,there is some significance for understanding the occurrence, development and prognosis of esophageal carcinoma.

Objective To explore the safety and feasibility of coronary angiography (CAG) via percutaneous left radial artery approach (LRA) compared with right radial artery approach (RRA) in aged patients, and determine whether LRA is a valid alternative for CAG. Methods A total of 502 consecutive patients who were aged 65 or older underwent diagnostic CAG were recruited and randomized to the LRA group (240 patients) or RRA group (262 patients). The study end points included total procedural duration, coronary time, fluoroscopy time, dose of radiation including cumulative air kerma and dose area product, contrast volume, and the incidence of vascular complications. Results Coronary procedural success rate was 96.2%(231/240) in LRA group and 96.2%(252/262) in RRA group. There was no significant difference (P>0.05). The radial cannulation time, fluoroscopy time, look through time, dose of radiation, contrast volume and the percentage of hydrophilic wire used in two group had no significant difference (P > 0.05). The catheter in place time in LRA was significantly shorter than that in RRA group:(2.7 ± 2.5) min vs. (3.3 ± 3.3) min, P=0.036). There was a trend toward shorter procedural duration in LRA group than that in RRA group, but there was no significant difference: (13.3 ± 6.1) min vs. (14.3 ± 6.2) min, P=0.075. Conclusions LRA approach has similar safety and feasibility in terms of performing coronary angiography compared with RRA.It seems to be a feasible alternative for CAG in aged patients.

Objective To establish a fluorescent polymerase chain reaction (PCR) method for rapid, sensitive and specific determination of -88/-123 polymorphisms in Myxovirus resistance protein A (MxA) gene promoter so as to provide molecular biology tool for optimized interferon-a treatment in chronic hepatitis B patients. Methods Hepatitis B virus (HBV) genotyping,serum HBV DNA level,and- 88/- 123 polymorphisms in MxA gene promoter of patients who had been treated with interferon-α were detected. The statistical analysis was done by using SPSS software to understand the relationship between MxA gene polymorphisms and interferon-α treatment. Afterwards, an optimal fluorescent PCR system was established to determine -88/-123 polymorphisms in MxA gene promoter. The sensitivity and the specificity of this system were confirmed by DNA sequencing. P-value of chi square test, odds ratios of regression analysis and 95% confidence intervals were employed. Results Patients with- 88 G/T and - 123 C/A in the interferon-stimulated response element in MxA gene promoter were interferon-α sensitive, while patients with - 88 GIG and - 123 C/C were not interferon-α sensitive. The coincidence rate of this system was 99.65% in comparison with DNA sequencing.Conclusion MxA gene polymorphisms could be rapidly and sensitively determined by this fluorescent PCR system.
