OBJECTIVETo explore the difference in the efficacy and effect mechanism of subcortical ischemic vascular disease (SIVD) complicated with depression between acupuncture and medication.

METHODSSixty patients were randomized-into an acupuncture group and a medication group, 30 cases in each one. In the acupuncture group, acupuncture was applied to Baihui (GV 20), Shuigou (GV 26), Fengfu (GV 16), Fengchi (GB 20) and the others, once a day, 6 times a week. The treatment of 4 weeks made one session and totally 2 sessions were required. In the medication group, nimodipine 30 mg, three times a day and fluoxetine 20 mg, once a day were prescribed for oral administration, for 8 weeks totally. Before treatment, at the end of the 4th week and at the end of the 8th week of treatment, cerebral blood flow velocity (CBFV) and solubility CD40 ligand (sCD40L) were determined respectively. The scores in Montreal cognitive assessment (MoCA) and Hamilton' s depression scale (HAMD) were evaluated in the two groups. The efficacies on cognitive function and depression symptoms were compared in the patients between the two groups. Results Compared with the outcome before treatment, mean blood flow velocity (Vm) of middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA) was increased significantly at the end of the 4th week of treatment in the two groups (all P<0.05). At the end of the 8th week, Vm was increased much significantly (all P<0.01). The differences were not significant in comparison between the two groups (all P>0.05). Compared with the expression before treatment, sCD40L was reduced significantly after treatment in the patients of the two groups (all P<0.01), but the differ- ence was not significant between the two groups (all P>0.05). Compared with that before treatment, MoCA score was increased significantly after treatment in the two groups (all P<0.01), HAMD score was reduced sig- nificantly (all P<0.01), the differences were not significant in comparison between the two groups (all P>0.05). The total effective rate of cognitive improvement was 86.7% (26/30) in the acupuncture group and was 80.0% (24/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05). The total effective rate of the improvement in depression was 93.3% (21/30) in the acupuncture group and was 86.7% (26/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05).

CONCLUSIONAcupuncture could significantly increases CBFV and reduces serum sCD40L expressions in the patients of SIVD complicated with depression, and significantly improves cognitive function and relieves depression symptoms. The efficacy of it is similar to that of western medication. The increase of serum sCD40L expression is possibly involved in the occurrence and development of SIVD. Reducing sCD40L expression contributes to the alleviation of damage induced by cerebral ischemia and reperfusion.

Now organophosphorus pesticides (OPs) bioremediation mainly means microbial bioremediation. However, phytoremediation has an advantage over microbial bioremediation because phytoremediation is safer and costs less than microbial bioremediation. Nevertheless, phytoremediation has limitations yet such as plants need better growth conditions and the efficiency of phytoremediation is lower. All these have confined the application of phytoremediation. Progresses of microbial bioremediation and phytoremediation of OPs were reviewed and OPs degrading enzymes and their organism sources, which are known by now, were summarized. Moreover, there are five important ways to enhance the efficiency of phytoremediation of OPs. They are culling plants, studying the action between soil and OPs, studying the genes that can resist or get rid of OPs, setting up the combined system of microbial bioremediation and phytoremediation and using degrading enzymes secreted selectively by roots.

OBJECTIVETo observe the expression of urotensin II (UII) on the lung of patients with pulmonary hypertension (PH) with congenital heart disease and investigate the meaning of this phenomenon.

METHODThirty eight patients with CHD were divided into three groups according to pulmonary arterial systolic pressure (PASP) measured in cardiac catheterization and surgery: normal pulmonary pressure group (N group, PASP < 30 mm Hg, n = 10), mild PH group (M group, PASP ≥ 30 mm Hg, n = 15), severe or moderate PH group (S group, PASP ≥ 50 mm Hg, n = 13). The expression of UII protein and UII mRNA in pulmonary arterioles were measured separately by immunohistochemical (IHC) analysis and in situ hybridization (ISH) analysis.

RESULT(1) The results of UIIIHC staining: The UII protein expression of group M was higher than that of group N (20.22 ± 3.58 vs. 14.34 ± 2.18, P < 0.01), but less than group S (20.22 ± 3.58 vs. 28.92 ± 3.22, P < 0.05). (2) The results of UIIISH mRNA staining were similar to IHC staining, the A value of group M was higher than group N (12.51 ± 2.02 vs. 8.85 ± 1.41, P < 0.05), less than that of group S(12.51 ± 2.02 vs. 25.35 ± 4.33, P < 0.01). (3) Correlation study: there was a positive correlation between the A values of UIIIHC and pulmonary hypertension (r = 0.64, P < 0.01, n = 38), a positive correlation between the A values of UIIISH and pulmonary hypertension (r = 0.58, P < 0.01, n = 38).

CONCLUSIONThere was the expression of Urotensin II protein and mRNA in the lung of pulmonary hypertension patients with congenital heart disease, and these expression may involve the formation of pulmonary hypertension of congenital heart disease.

OBJECTIVETo explore the correlation between the recurrence of cerebral infarction and aspirin resistance (AR)/Chinese medical (CM) constitutions.

METHODSTotally 413 cerebral infarction patients took Aspirin Enteric-coated Tablet (100 mg per day) while receiving routine therapy, 5 days at least in a week. They were followed-up for 12 months. Aspirin sensitivity (AS) was determined using turbidimetry. CM constitutions among patients with different AS were compared. Ratios of AR patients and AS patients of different CM constitutions in cerebral infarction recurrent patients were compared. Platelet membrane glycoproteins (GP) II b HPA-3 gene polymorphism was detected by polymerase chain reaction (PCR) method. Correlation between recurrence of cerebral infarction and AR, bb genotypes, CM constitutions times AS were analyzed by Logistic regression.

RESULTSTotally 11 patients dropped out, 101 (25.12%)with recurrent cerebral infarction and 301 (74.88%) without recurrent cerebral infarction. There were 152 (37.81%) AR patients and 250 (62.19%) AS patients. AR accounted for 26.6% (80/ 301) and AS accounted for 73.4% (221/301) in non-recurrent cerebral infarction patients. AR accounted for 71.3% (72/101) and AS accounted for 28.7% (29/101) in recurrent cerebral infarction patients. There was statistical difference in AR and AS ratios (χ2 = 64.287, P = 0.000). The proportion of yin deficiency constitution (YDC) was the largest [28.3% (43/152)] in AR patients. The proportion of blood stasis constitution (BSC) was the largest [23.6% (59/250)] in AS patients. There was statistical difference in CM constitutions between AR patients and AS patients (χ2 = 21.574, P < 0.01). The former 4 recurrent rates occurred in AR patients of YDC, BSC, damp-phlegm constitution (DPC), qi deficiency constitution (QDC). YDC occupied the first place [22.4% (34/152)]. The former 4 recurrent rates occurred in AS patients of BSC, QDC, DPC, damp-heat constitution (DHC). BSC occupied the first place [3.2% (2/250)]. Compared with non-recurrent cerebral infarction patients and AS patients, bb gene occurred most often, but aa gene and ab gene occurred obviously lesser in non-recurrent cerebral infarction patients and AR patients (χ2 = 20.171, χ2 = 55.139, P < 0.01). AR and bb gene were positively correlated with recurrent cerebral infarction (OR = 18.423, P = 0.000; OR = 1.304, P = 0.028). Body constitutions interacted with AS (OR = 0.707, P = 0.000).

CONCLUSIONSRecurrent cerebral infarction was closely related to AR and constitutional types. The recurrence rate was higher in AR patients of YDC. GP I b HPA-3 bb genotype might be a risk factor for AR and recurrent cerebral infarction.

Objective To explore risk factors of oxygen saturation (SpO2) decrease during intrahospital transporta-tion (IHT) of intensive care unit (ICU) patients in emergency department,and provide theoretical basis for prevent-ing oxygen saturation decrease during intrahospital transportation. Methods A cross-sectional study design was adopted,from April to May,2017,we investigated 182 ICU patients who required IHT in an emergency department in a tertiary hospital in Shanxi Province by using self-designed Evaluation Form of Intrahospital Transportation for ICU Patients in Emergency Room. We divided patients into two groups based on whether their SpO2 decreased or not. Risk factors of SpO2 decrease were identified by univariate and multivariate Logistic regression analysis. Results Among 182 patients,117 had SpO2 decrease,and the rate of SpO2 decrease was 64.3%. Patient's age,MEWS score, disease type,escort personnel,and oxygen supply device were risk factors of SpO2 decrease. Conclusion SpO2 de-crease is the result of combination of multiple risk factors during IHT. We ought to enhance training of escort person-nel,assess patient's condition and SpO2 level accurately and make plan before transportation,choose qualified oxygen supply device to ensure patients can have effective oxygen supply during IHT,which prevent SpO2 decrease during IHT.

OBJECTIVETo investigate the induction of apoptosis on human oral epidermoid carcinoma KB cells and multidrug resistant KBv200 cells by Matrine.

METHODSMTT assay was used to investigate the inhibition ability of Matrine on the cells in vitro. Transmission electron microscope was used to observe the ultrastructure feature of cells. after treated by Matrine. Acridine orange (AO)/Ethidium bromide (EB) fluorescent staining and flow cytometry were used to observe apoptosis induced by Matrine. Flow cytometry was applied to study the effects of the drug on cell cycles of the cells.

RESULTSWhen 0.50, 1.00, 1.50, 2.00 mg/ml of Matrine was used, the vital rates of KB and KBv200 cells were decreased according to Matrine's concentration. The IC50 concentrations of Matrine on KB and KBv200 cells were 1.35 mg/ml and 1.43 mg/ml individually. The results of AO/EB fluorescent staining and flow cytometry showed that Matrine could induce apoptosis of two kinds of cells. While observed by transmission electron microscope, there were more contraction of cells, condensation of nuclei, bubble of cytoplasm in both kinds of cells after treated by Matrine. Matrine could stop the growth of KB and KBv200 cells at S period and restrain mitosis of cells.

CONCLUSIONMatrine can inhibit the growth of KB and KBv200 cells by inducing apoptosis. The apoptosis effect is dose-dependent and it has certain relation to the blocking of S period cells.

BACKGROUNDLaminectomy is a major method to treat lumbar spinal stenosis (LSS), but it has lots of flaws such as scar tissue can form around the dura again or spinal instability. This study aimed to investigate the feasibility of transverse rotation laminoplasty (TRL) in the treatment of LSS.

METHODSThe mimic operations of TRL were performed both in the computerized image processing and on the lumbar specimen. Computed tomography (CT) images were either collected from 80 clinical patients with complaints of lumbago or obtained from 40 sets of lumbar specimens after rebuild of spinal canals. In the CT image processing the heights of the spinous process and laminae at L3-L5 were measured. The total length of the spinous process plus one side laminae after the operation was evaluated and compared with the length of inner margin of pedical before the operation. The areas of the vertebral canal were examined before and after the operation.

RESULTSIn the CT images, the height of spinous process of L3, L4 and L5 was 24.74 ± 3.45, 22.68 ± 5.96 and 21.54 ± 4.12 mm respectively, and that of laminae was 23.66 ± 2.32, 22.68 ± 5.36 and 20.99 ± 3.67 mm respectively (P > 0.05). Distance of inner border of pedical of L3, L4 and L5 was 23.01 ± 6.59, 24.65 ± 5.54 and 26.03 ± 7.34 mm respectively, and length of spinous process with laminae of those was 29.76 ± 4.91, 29.31 ± 6.43 and 32.53 ± 5.76 mm respectively (P < 0.05). Preoperative area of spinal canals of L3, L4 and L5 was 299.81 ± 10.09, 297.66 ± 9.54 and 308.22 ± 10.04 mm2 respectively, and postoperative area was 480.01 ± 9.33, 487.32 ± 8.65 and 501.03 ± 9.12 mm2 respectively (P < 0.05). In the human lumbar vertebrae specimen, the data similar to the former.

CONCLUSIONSThe excised canal posterior was covered, and the lumbar canals enlarged by TRL. The TRL provided a new alternative in the treatment of LSS.

OBJECTIVETo study the effect of testosterone propionate (TP) on the distribution pattern of calcitonin gene-related peptide (CGRP) in two types of motoneuron (Mn) pools in rats.

METHODThe double labeling of cholera toxin B subunit coupled with colloidal gold (CB-Au) retrograde identification combining with immunocytochemistry was mainly used to reveal the distribution pattern of CGRP-like immunoreactivity (CGRP-LI) and its changes in the motoneuron pools labeled by CB-Au.

RESULTTP injected intramuscularly 28 days later significantly decreased CGRP expression in Mn pool innervating extensor digitorum longus (EDL, fast-twitch), comparing with corresponding control and castration group respectively (P < 0.001), while no significant effect on Mn pools innervating soleus (SOL, slow-twitch, P > 0.05) was observed.

CONCLUSIONEDL-Mn pool is more sensitive to testosterone propionate than SOL-Mn pool in regulating CGRP expression.
