Objective To investigate the correlation between ischemic stroke and both the risk factors and the degree of intracranial arterial stenosis, and provide evidence of preventing ischemic stroke. Methods Ninety patients with ischemic stroke were assessed by digital substraction angiography (DSA) and, accordingly, divided into group A (stenosis<30%) and group B (stenosis ≥30% or occlusion). The data about such risk factors as age, gender and family history, the levels of T-cholesterol (CHO), triacylglycerol (TG), high/low density lipoprotein cholesterin (H/LDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB) and lipoprotein A (Lpa) were recorded and analyzed; such diseases as hypertension, hyperlipemia, diabetes mellitus and coronary disease were taken into consideration. Results The incidence rate of intracranial arterial stenosis in these patients with ischemic stroke was 67.78%. Stenosis occurred most frequently in the middle cerebral arteries, less frequently in the intracranial segments of the internal carotid artery and the vertebral-basilar artery with the lowest occurrence in the posterior cerebral artery. Patients with ischemic cerebrovascular disease accompanied by high blood pressure, diabetes were more likely subjected to intracranial arterial stenosis; the regression coefficient, OR values, P values in patients with hypertension and diabetes were (1.659, 5.256 and 0.002) and (1.657, 5.241, and 0.046), respectively. The level of HDL-C (mmol/L) in the group B (0.99±0.30) was significantly lower than that in the group B (1.30±0.50, t=-3.603, P=0.001). Age, gender, smoking, stroke history, family history of cerebrovascular disease, the level of TC, TG, LDL-C, ApoA, ApoB, serum Lpa between the 2 groups showed no significant differences (P>0.05). Conclusion The major risk factors of intracranial arterial stenosis include hypertension, diabetes mellitus with HDL-C as its protective factors.

Objective To evaluate the clinical efficacy and safety of phloroglucinol in patients during coloscopy.Methods A total of 164 patients who were prepared for coloscopy were randomized divided into experiment group ( n =88 ) and control group ( n =76 ) . All of the patients in the two groups were given food easy to digest 3 days before coloscopy and given polyethylene glycol electrolyte powder orally 12 and 6 hours before coloscopy.The carbom dioxide was used as the expansion of the gas, and patients in the experiment group were given phloro-glucinol 40 mg by intramuscular injection 10 minutes before the colosco-py, and those in the control group were given 0.9%NaCl 2 mL by intra-muscular injection.The data of visual analogue score( VAS) , rate of co-loscopy examination reached to the cecum, blood pressure and heart rate before and after the examination between the two groups were recorded. Results The VAS score were ( 4.1 ±1.4 ) and ( 6.3 ±1.5 ) points in the experiment and control group respectively, with experiment group significantly lower than the control group ( P<0.05 ) .The reach cecum rate was 90.9%in experiment group and 89.5%in control group, which indicated no statistical difference between the two groups ( P>0.05 ) .The blood pressure and heart rate of the two groups were not statistically different in the procedure of coloscopy (P>0.05).Conclusion Phloroglucinol can significantly decrease the VAS in the procedure of coloscopy, without increasing the incidence of adverse drug reactions.

Objective: To analyze the data of malignant tumor mortality and change in disease burden in Hebei province from 1973 to 2013. Methods: Cancer mortality rate, age-standardized mortality rate and the years of life lost due to premature mortality (YLLs) were calculated by using the data from three rounds of all death causes survey and database of cancer registry in Hebei during 1973-2013. Results: From 1973 to 2013, a linear upward of malignant tumor mortality was observed, with a 51.57% increase. The mortality rate during 1973-1975 was 98.52/100 000 and it was 149.33/100 000 during 2011-2013. During 1973-1975, the YLLs was 17.0/1 000 in males and 12.8/1 000 in females. While during 2011-2013, the YLLs was 23.2/1 000 in males and 15.9/1 000 in females. During 1973-1975, esophagus cancer, stomach cancer and liver cancer were top three leading causes of deaths. During 2011-2013, lung cancer, stomach cancer and liver cancer were main leading causes of deaths. During the past 40 years, the deaths of esophagus cancer and cervix cancer decreased dramatically, but the deaths of lung cancer and breast cancer increased sharply. Conclusions: The disease burden caused by malignant tumor is becoming more serious in Hebei. It is necessary to strengthen the primary prevention and screening of malignant tumor.

OBJECTIVETo investigate the clinical value of glycosylated G-CSF combined with middle-high dose cyclophosphamide (Cy) or conventional chemotherapy with increased dose of Cy for mobilizing peripheral blood progenitor cells in patients with tumor.

METHODSThirty patients from four hospitals in Beijing region were enrolled in this clinical study. Diagnoses of the patients were non-Hodgkin' lymphoma (n = 21), Hodgkin disease (n = 1), breast cancer (n = 7) and ovary cancer (n = 1). Autologous peripheral blood progenitor cells (APBPC) were mobilized by middle-high dose Cy or conventional chemotherapy with increased dose of Cy combined with G-CSF. G-CSF was given subcutaneously from the nadir of the white blood cell (WBC) count to the end of PBPC collection. The dosage of G-CSF was 250 microg/d in 29 patients and 500 microg/d in 1 patient. When WBC count was > 5 x 10(9)/L, APBPC were harvested with CS 3000 plus/COBE Spectra.

RESULTSThe average dosage of Cy was 3.95 g (2.3 g/m(2)). The doses of G-CSF were 3.1 approximately 6.4 microg x kg(-1) x d(-1). Thirteen patients (43%) were collected twice, 14 patients (47%) three times and 3 patients (10%) four times. All of the patients could tolerate the treatment regimens. Seven patients had bone pain after G-CSF injection and one was severe, one patient had headache and one had nausea and vomiting.

CONCLUSION250 microg glycosylated G-CSF combined with middle-high Cy or conventional chemotherapy with increased dose of Cy combined G-CSF is an optimal method for APBPC mobilization in tumor patients.

OBJECTIVETo explore the protective effect of tanshinone II A on lipopolysaccharide (LPS)-induced lung injury in rats, and possible mechanism.

METHODSLPS (O(111): B4) was used to produce a rat model of acute lung injury. Sprague-Dawley rats were randomly divided into 3 groups (8 in each group): the control group, the model group (ALI group), and the tanshinone II A treatment group. Expression of adhesion molecule CD18 on the surface of polymorphonuclear neutrophil (PMNCD18) in venous white blood cells (WBC), and changes in coagulation-anticoagulant indexes were measured 6 h after injection of LPS or normal saline. Changes in malondialdehyde (MDA) content, wet and dry weight (W/D) ratio and morphometry of pulmonary tissue as well as PMN sequestration in the lung were also measured.

RESULTS(1) When compared with the control group, expression of PMNCD18 and MDA content were enhanced in the ALI group with a hypercoagulable state (all P<0.01) and an increased W/D ratio (P<0.05). Histopathological morphometry in the lung tissue showed higher PMN sequestration, wider alveolar septa; and lower alveolar volume density (V(V)) and alveolar surface density (S(V)), showing significant difference (P<0.01). (2) When compared with the ALI group, the expression of PMN-CD18, MDA content, and W/D ratio were all lower in Tanshinone II A treatment group (P<0.05) with ameliorated coagulation abnormality (P<0.01). Histopathological morphometry in the lung tissue showed a decrease in the PMN sequestration and the width of alveolar septa (both P<0.01), and an increase in the V(V) and S(V) (P<0.05, P<0.01).

CONCLUSIONTan II A plays a protective role in LPS-induced lung injury in rats through improving hypercoagulating state, decreasing PMN-CD18 expression and alleviating migration, reducing lipid peroxidation and alleviating pathological changes.

OBJECTIVETo observe the effect of acupuncture combined physical training and relearning on stroke patients.

METHODSA multi-center, randomized controlled trial design was adopted. A total of 364 stroke patients were recruited and randomly assigned to the experimental group (184 cases) and the control group (180 cases). Patients in the experimental group received acupuncture combined with physical training and relearning, while those in the control group only received physical training and relearning. All received four weeks of treatment. Effects on Fugl-Meyer motor function, neurological impairment, activities of daily living difference were compared before treatment, after treatment, 2 and 5 months after follow-ups between the two groups.

RESULTSTotally 353 patients completed this trial, 179 in the experimental group and 174 in the control group. (1) compared with before treatment, brief Fugl-Meyer motor functions scores and FIM scored obviously increased, and scores for neurological impairment obviously decreased in the two group. Besides, the increment of brief Fugl-Meyer motor functions scores and FIM scores was obviously higher in the experimental group than in the control group at month 2 and 5 of follow-ups; scores for neurological impairment was obviously lower in the experimental group than in the control group. The increment of FIM scores was obviously higher in the experimental group than in the control group at month 5 of follow-ups (P < 0.05, P < 0.01). (2) There was statistical difference in inter-group comparison of total Fugl-Meyer motor functions scores and FIM scores, or scores for neurological impairment (P < 0.01). The improvement of Fugl-Meyer motor functions grading and neurological impairment grading was obviously superior in the experimental group at month 2 and 5 of follow-ups. The distribution of FIM grading was also better in the experimental group at month 5 of follow-ups (P < 0.05, P < 0. 01).

CONCLUSIONSBoth acupuncture combined exercise training and relearning and physical training and relearning could effectively promote the rehabilitation of stroke patients, reduce their neurological impairment degrees, improve motor functions and independent capacities. Better long-term efficacy could be obtained by acupuncture combined exercise training and relearning.
