Objective To observe the therapeutic effect of consciousness-restoring needling combined with comprehensive rehabilitation training on motor function and the activities of daily living of poststroke patients with hemiplegia. Methods Sixty qualified patients were evenly randomized into observation group and control group. All of the patients were given conventional medicine treatment and conventional rehabilitation training, and the treatment group was given consciousness-restoring needling additionally. The therapeutic effects were compared at the end of first session of treatment for 4 weeks and 12 weeks after the first session of treatment. The Fugl-Meyer motor assessment scale (FMA), modified Barthel Index (MBI) and Stroke-Specific Quality of Life Scale ( SS-QQL) were taken as the main evaluation indexes. Results The differences of FMA, MBI and SS-QOL scores were insignificant between the two groups before treatment ( P>0.05). At the end of treatment for 4 weeks, FMA, MBI and SS-QOL scores were increased in the two groups (P<0.05), and the increase was more obvious in the observation group (P<0.05). The results of follow-up till the 12th week showed that FMA, MBI and SS-QOL scores were still higher than the baseline level ( P<0.05). Conclusion Consciousness-restoring needling combined with comprehensive rehabilitation training has better effect on improving motor function and the activities of daily living of poststroke hemiplegia patients than comprehensive rehabilitation training alone.

Objective To optimize the high performance liquid chromatography (HPLC) method for determining the content of scopoletin from Caulis Erycibes.

The detection wavelength was 298 nm and the flow rate was set at 1.0 mL/min. Results The linear range of scopoletin from Caulis Erycibes was 2.83-118 μg/mL, and the recovery rate was 99.47% ( sR=1.07%). Conclusion The optimized method is simple, specific and accurate, and can provide reference for content determination of scopoletin in Caulis Erycibes.

OBJECTIVETo explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

METHODSTotally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e., the rehabilitation group, the Chinese medical treatment group, the acupuncture group, and the comprehensive rehabilitation group, 30 cases in each group. Based on routine rehabilitative training, patients in the Chinese medical treatment group, the acupuncture group, and the compre-hensive rehabilitation group received standardized treatment based on syndrome typing, Shi's Consciousness-Restoring Resuscitation acupuncture, Chinese herbs + acupuncture comprehensive rehabilitatino protocol, respectively. The treatmet cycle consisted of 4 weeks with 24-week follow-ups. Fugl-Meyer motor assessment (FMA), Modified Barthel Index (MBI), and Stroke-Specific Quality of Life Scale(SS-QQL), and safety assessment were taken as main effect indices before treatment, at week 4 of treatment, at week 12 and 24 of follow-ups, respectively.

RESULTSThere was no statistical difference in FMA score, MBI score, SS-QOL score among the four groups before treatment (P > 0.05). These scores were significantly improved in the four groups at week 4 of treatment, week 12 and 24 of follow-ups, respectively (P < 0.05). Besides, FMA score and SS-QOL score were significantly improved in the comprehensive rehabilitation group at each corresponding time point, as compared with other treatment groups (P < 0.05).

CONCLUSIONSThe comprehensive protocol could significantly improve motor function, activity of daily living in hemiplegia patients after stroke, and further improve their QOL. Its effect was better than other single treatment.

OBJECTIVETo investigate the intervention and mechanism of ambroxol combined with low-dose heparin on oxidative stress, TNF-alpha and IL-1beta in rabbits with acute lung injury (ALI).

METHODSTwenty-four healthy Japanese rabbits were randomly divided into three groups: (1) Normal saline control group (NC), (2) Oleic acid injury group (OA), (3) Ambroxol + low-dose heparin therapy group (AH). After the success of ALI model, AH group was injected ambroxol + low-dose heparin, while the NC group and OA group were injected the same dose of normal saline by the same method. Arterial oxygen tension (PaO2), tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) at different time points were determined. The pathological manifestation of both side lungs was observed at the end of expeiment. The activity of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), xanthine oxidase (XO) and the content of malondialdehyde (MDA) in bronchoalveolar lavage fluid (BALF) and lung tissue homogenate were tested. The apoptosis index was detected. The lung wet/dry (W/D) ratio was calculated. The pathological changes in lung tissue were observed by light microscopy, and the ultrastructural changes of lung tissue were observed by electron microscopy.

RESULTS(1) The instructive injury induced by ALI observed under electron microscope and light microscope and W/D was decreased significantly in AH group. (2) PaO2 was improved significantly in AH group, compared with that in OA group (P < 0.01). (3) The activity of GSH-Px and SOD in AH group increased significantly (P < 0.01 or P < 0.05) but the activity of XO and the content of MDA decreased significantly (P < 0.01), compared with those in OA group. (4) Except the content of IL-1beta in serum before treatment, the content of IL-1beta and TNF-alpha in serum, BALF, lung tissue homogenate of OA group increased significantly (P < 0.01), and those were obviously improved in AH group. (5) Apoptosis index (AI) in AH group decreased significantly (P < 0.01) compared with that in OA group.

CONCLUSIONIn ALI induced by OA, IL-1beta and TNF-alpha increases significantly and involved in the occurrence and development of ALI. Ambroxol combined with low-dose heparin can reduce lung cells oxidative stress to inhibit the release of IL-1beta and TNF-alpha, which play a role in the treatment of ALI.

OBJECTIVESTo study the correlation between positive rates of RNA in clinical confirmed severe acute respiratory syndrome (SARS) patients and its appearance in relation to the development of the disease in order to provide scientific basis for early diagnosis, effective prevention and treatment of the disease.

METHODSOne-step reverse transcription-polymerase chain reaction (RT-PCR) was used to amplify the SARS RNA in the clinical specimens from different courses of the disease. The representative amplicons were then sequenced. Chi-square for trend test was performed to study the correlation between positive rates of RT-PCR and at different periods after the onset of the disease.

RESULTSThe fragments amplified from the sputum specimens of SARS patients were shown to share 100% homology with the published SARS-associated coronavirus. Of the different clinical specimens, positive rate in the stools appeared to be the highest (21.55%). Chi-square for trend test revealed that the positive rates of stools and sputa of SARS patients decreased with the development of the disease (chi(2) for trend = 12.55 and 16.408, P = 0.0004 and P = 0.000 05 respectively).

CONCLUSIONOne-step RT-PCR proved to be an effective method for the detection of SARS-associated coronavirus from clinical specimens. Data as indicated that the positive rates of SARS coronavirus were decreasing in SARS patients along with the disease progression.

Objective:To explore the trans-membrane signaling mechanism of interleukin-6 (IL-6)-induced osteogenic differentiation and calcification of human umbilical artery smooth muscle cells (HUASMCs).Methods:HUASMCs were primarily cultured in vitro and were stimulated with IL-6, IL-6+solutable IL-6 receptor (sIL-6R), IL-6+sIL-6R+solutable gp130 (sgp130), or vehicle (blank control). Alizarin red and Von Kossa staining were used for detecting cell calcification, Western blot was used to test the protein expression of tissue-nonspecific alkaline phosphatase (TNAP), osteopontin (OPN), bone morphogenetic protein-2 (BMP-2) and Runt related transcription factor 2 (Runx2), and immunofluorescence was used to examine the mIL-6R expression of HUASMCs. The comparison of measurement date between the two groups was conducted by t-test. The comparison of measurement date between multiple groups was conducted by one-way analysis of variance (ANOVA). Results:The intensity severity of calcification stain was IL-6+sIL-6R group >IL-6+sIL-6R+sgp130 group>IL-6 group=blank control. After stimulated for 12 hours, the TNAP expression in blank control, IL-6 group, IL-6+sIL-6R group, IL-6+sIL-6R+sgp130 group were (0.44±0.08), (0.52±0.14), (0.84±0.16) and (0.55±0.10) respectively ( F=290.96, P<0.001). After stimulated for 3 days, the OPN expression in blank control, IL-6 group, IL-6+sIL-6R group, IL-6+sIL-6R+sgp130 group were (0.61±0.84), (0.95±0.16), (1.65±0.24) and (0.99±0.10) respectively ( F=507.72, P<0.001). After stimulated for 12 hours, the BMP-2 expression in blank control, IL-6 group, IL-6+sIL-6R group, IL-6+sIL-6R+sgp130 group were (0.77±0.05), (1.69±0.16), (2.81±0.26) and (0.57±0.12) respectively ( F=959.09, P<0.001). After stimulated for 3 days, the Runx2 expression in blank control, IL-6 group, IL-6+sIL-6R group,IL-6+sIL-6R+sgp130 group were (0.57±0.03) , (0.92±0.10), (1.31±0.13) and (0.66±0.06) respectively ( F=1141.27, P<0.001). Comparing with Jurkat cells (positive control) and CEM cells (negative control), HUASMCs limited expressed mIL-6R. Conclusion:IL-6 may induce HUASMCs osteogenic differentiation and calcification mainly via the sIL-6R-mediated trans-signaling pathway.

OBJECTIVETo investigate the prevalence of Anaplasma phagocytophilum in rodents from forest areas in northeastern China.

METHODSPCR amplification, followed by sequence analysis was carried out. The sequences of 16S rRNA and gltA gene fragment amplified from rodent specimens were compared with corresponding part of the sequences deposited in GenBank.

RESULTSA total number of 276 rodents were tested, including 102 in Jilin province, 61 in Helongjiang province and 113 in Inner Mongolia autonomous region. The positive rates were 8.82%, 1.64% and 0.00%, respectively. The infection rate in rodents infected by ticks was 11.30 times higher than that in rodents without ticks (P = 0.002). The S. A. phagocytophilum 16S rRNA sequences from rodents in Jilin and Heilongjiang were identical and differed in 3-5 bases compared with the corresponding parts of A. phagocytophilum from America, Sweden and Japan. Compared with the sequences registered in GenBank, the nucleotide sequence of gltA varied from 87%-97% and its deduced amino acid sequence changed from 84%-99%.

CONCLUSIONA. phagocytophilum infection was presented in rodents from Jilin and Heilongjiang province.

OBJECTIVEThis clinical study was designed to evaluate the efficacy and toxicity of the combined regimen of docetaxel, 5-Fu and DDP (TPF) in the treatment of advanced or relapsed nasopharyngeal carcinoma (NPC).

METHODSFifty-six patients with newly diagnosed or recurrent/metastatic NPC following chemotherapy or radiotherapy were enrolled. Both docetaxel and DDP were administered intravenously for 6 hours at the dose of 70 mg/m2 on D1. 5-Fu was given at a dose of 400-500 mg/m2 for 6 hours from D1 to D5. Dexamethasone was routinely administered before injection of docetaxel. This combination was repeated every 3 to 4 weeks, and continued for 4-6 cycles or until PD for the responders.

RESULTSFifty-one (91.1%) patients were evaluable for response assessment. The response rate for whole group was 72.5% (37/51) with a CR rate of 9.8% (5/51). The stable disease accounted for 17.6% (9/51). There were 17(30.4%) chemotherapy-naïve patients. The overall response rate in those was 82.4% with a CR rate of 29.4%. However, the response rate for previously treated patients was 64.7% without CR. Twelve patients had progressed disease, including 5 (8.9%) died of disease progression with a median follow-up of 11 month (ranged from 1 to 19 months). Totally, 196 courses of chemotherapy were administered. The major toxicity was myelosupression, nausea/vomiting. The incidence of leucopenia was 48% with 22.2% of these in NCI grade II or IV. But only 2 patients (3.6%) experienced leucopenia with a fever. Other mild toxicities including alopecia, asthenia, mucositis and diarrhea were also observed.

CONCLUSIONOur preliminary outcome shows docetaxel, 5-Fu and DDP combination is effective and safe for the patients with advanced or relapsed nasopharyngeal carcinoma. But further clinical study is warranted.

OBJECTIVETo explore the temporal profile of serum antibody against coronavirus in patients with severe acute respiratory syndrome (SARS), and to evaluate the reliability of indirect immuno-fluorescence assay (IFA) in the diagnosis of SARS.

METHODSClinically confirmed SARS patients, suspected SARS patients, and controls were included in the study. IFA was used to detect the serum antibody against SARS coronavirus. General information about the subjects was collected using a standard questionnaire.

RESULTSThe positive rates of specific IgG and IgM against SARS virus within 10 days after onset of the disease were 55.1% and 16.3% respectively and then increased up to 89.8% for IgG and 65.3% for IgM. After 25 days of the onset of the disease, 90.9% patients became positive for both IgG and IgM. Results from chi-square for trend test revealed that the positive rates of both IgG and IgM increased with time (chi(2) for trend = 16.376, P = 0.00005 for IgG; chi(2) for trend = 28.736, P = 0.00000 for IgM). Sensitivity, specificity and agreement value of IFA regarding the diagnosis of SARS were all higher than 90%.

CONCLUSIONIFA can be used to assist diagnosis of SARS after 10 days of the onset of disease.

OBJECTIVETo analyze the genetic differences of Orientia tsutsugamushi (Ot) Sta56 gene between Shandong isolates and other strains deposited in GenBank.

METHODSPCR and restriction fragment length polymorphism (RFLP) were used to amplify the complete sequence of Ot-Sta56 gene. RFLP profiles of Ot were predicted by a computer program according to their complete sequences of Ot-Sta56 gene. PCR amplicon from XDM2 strain was sequenced and analyzed by Clustal X (1.8) and PHYLIP software.

RESULTSThe complete sequences (about 1.6 kbp) of Ot-Sta56 gene were amplified from B16 strain (isolated from patients), FXS2 strain (isolated from A. agrarius) and XDM2 strain. Four species of restriction endonucleases (Hha I, Hinf I, Hae III, Pst I) were used to digest the PCR amplicons from the 3 isolates. When comparing with the RFLP profiles of prototype Ot, the RFLP profiles of PCR amplicons from the 3 isolates were similar to those of Japan Kawasaki strain, but were quite different from the international reference strains Gilliam, Karp, Kato. Results from DNA sequence analysis showed that the complete sequence of Ot-Sta56 gene homology to Japan Kawasaki strain of XDM2 strain was 97%, and deduced amino acid sequence was 92%.

CONCLUSIONData from the complete sequence of Sta56 gene indicated that the genotypes of Ot isolates in Shandong province were similar, but with distinction from the Kawasaki strain.
