Objective: To observe the therapeutic effects of needle warming moxibustion for chronic diarrhea. Methods: Two-hundred cases with chronic diarrhea were divided randomly into a treatment group and a control group. 100 cases in the treatment group were treated with needle warming moxibustion on specific acupoints. 100 cases in the control group were treated by oral administration of Smecta. Results: The therapeutic results showed cure in 52 cases, remarkable effect in 34 cases, improvement in 14 cases and the total effective rate in 100.0% in the treatment group, and cure in 5 cases, remarkable effect in 23 cases, improvement in 33 cases, failure in 39 cases and the total effective rate in 61.0% in the control group. The comparison of the total effective rate between the two groups was statistically significant (P<0.05). Conclusion: The needle warming moxibustion on specific acupoints is better than oral administration of Smecta in the therapeutic effects.

Objective To evaluate the relationship between the lung volume (LV) in inspiration and expiration,pulmonary function tests(PFT),and other CT measurements of emphysema index (EI) and mean lung density (MLD) in patients with chronic obstructive pulmonary disease (COPD).Methods Seventy-six patients with COPD were included.Three-dimension analysis was performed to obtain the following CT parameters on the inspiratory and expiratory phases:EI,MLD,LV.The ratios and differencesof MLD and LV between the two phases were calculated(ΔMLD,ΔLV,MLDex/in,LVexin).Not only the linear correlations between the lung volume parameters and PFT but also the correlations of lung volume parameters with the other CT parameters were tested by the Spearman rank correlation test and multivariant step wise regression.Results LVex/in had negative correlations with forced expiratory volume in 1 second ％ predicted [FEV1 ％,(54.32 ± 7.11)] and the ratio of forced expiratory volume in 1 second to forced vital capacity [FEV1/FVC,(49.12 ±8.01)％] (r =-0.69,-0.56,P ＜0.01),but it had the positive correlation with the ratio of residual volume to total lung capacity [RV/TLC,(58.03 ± 8.55) ％,Spearman coefficients 0.66,P ＜ 0.01].LV/exin (0.67 ± 0.12) was positively correlated with MLDex/in (0.89 ± 0.04,r =0.88,P ＜0.01).The further multivariate step wise regression denonstrated that EI,LV and MLD could introduce a regression equation with R2 =0.77 and 0.73,respectively (P ＜ 0.01).Conclusions There is an association between LVex/in and the parameters of routine PFT,which can reflect the collapsibility of lung.Moreover,LVex/in can be considered to be equivalent to MLDex/in.Taking into account the impact of scanning parameters on MLDex/in,LVex/in may play a complementary role in the assessment of pulmonary function.

BACKGROUND:To inhibit the expressions of prothrombin activator inhibitor 1 and tissue plasminogen activator is one potential target for the treatment of cerebral infarction. OBJECTIVE:To investigate the expressions of serum inflammatory cytokines in rats with cerebral infarction undergoing bone marrow mesenchymal stem cel transplantation combined with edaravone. METHODS:Sixty Sprague-Dawley rats were enrol ed to prepare models of focal cerebral infarction by middle cerebral artery occlusion, and were randomly divided into four groups. Rats were given intravenous injection of PBS via tail veins for 5 consecutive days as model group, rats were subjected to intravenous injection of 2.0×109/L bone marrow mesenchymal stem cel suspension (1 mL) via tail veins, twice daily for 5 days as stem cel transplantation group, and those were given intravenous injection of 30 mg edaravone combined with intravenous injection of 2.0×109/L bone marrow mesenchymal stem cel suspension (1 mL) via tail veins for 5 days, twice daily, as combined group. RESULTS AND CONCLUSION:Compared with the model group, modified neurologic severity scores were lower, expressions of serum prothrombin activator inhibitor 1 and tumor necrosis factor-αmRNA in the brain decreased, and the infarct area reduced in the stem cel transplantation and combined groups. And the changed levels of above indicators in the combined group were significantly larger than those of the stem cel transplantation group. In conclusion, combination of bone marrow mesenchymal stem cel transplantation with edaravone can promote neural function recovery after cerebral infarction.

In this paper, taking Shijiazhuang city, Hebei province as an example, a random sampling of 30 streets in three districts were investigated the use of tactile ground surface indicator. The survey showed that 69% of the existing tactile ground surface indicator were used normally, while 8%were laid unreasonable, 11%were occupied and 12%were damaged. Suggestions were set from three aspects:sci-entific and reasonable laying, strengthening supervision and maintenance, and strengthening publicity and education, so as to improve the current situation of tactile ground surface indicator, improve the utilization rate, promote the participation of visually impaired persons in so-cial life and improve their quality of life.

Objective To explore the effect of high voltage alternating electric field therapy on fracture healing in rats. Methods An animal model of cortical bone defect was successfully established in the unilateral proximal tibia of 41 rats.They were then randomized into an experimental group (21 rats) and a control group (20 rats).The animals in the experimentsl group were given high voltage alternating electric field therapy for 30 minutes daily,while those in the control group only had sham exposure to the high voltage alternating electric field therapy.Rats in each group were sacrificed at days 7,14,21 and 28 post-operation.After blood collection,the operated tibias of the rats were resected with muscle and other soft tissue removed.Bone mineral density (BMD) of the callus at the fracture point was measured using dual energy X-ray absorptiometry (DEXA).The calluses were then cut down and fixed,decalcificated and sliced for histological observation.At the same time serum osteocalcin ( OC ) and bone alkaline phosphatase (RAP) were also detected by ABC-ELISA. Results The BMD examination showed that callus BMD in the experimental group was significantly higher than in the control group at days 14 and 28.Serum OC and RAP in the experimental group were also higher at days 14 day 21,and OC was still significantly higher in the experimental group at day 28.Histological examination showed that in the early stages of bone healing hematoma absorption and organization appeared earlier in the experimental group than in the control group,with remarkable osteoblast and chondroblast proliferation.While at the later stage,bone trabeculas connection and mineralization also appeared earlier in the experimental group than in the control group. Conclusions High voltage alternating electric field therapy may promote fracture healing by accelerating hematoma absorption and organization,elevating osteoblast proliferation and differentiation as well as promoting extracellular matrix secretion and mineralization.The underlying therapeutic mechanism might be related to the increased expression of OC and RAP caused by exposure to the high voltage alternating electric field.

Phospholipase D(PLD) is ubiquitous in bacteria,fungi,and mammal.In pathogenic microorganisms,PLD can be pathogenic determinant and play a role in spore generation.In mammalian cells,PLD functions in several signal transduction pathways,such as membrane transportation,mitosis regulation,and actin cytoskeleton regulation.In the process of pathogens invasion host cells,both of the pathogen and host cells’ PLD will be activated and a series of cascade reaction will be generated.During this process,pathogen’s PLD can regulate the polymerization and reorganization of its own actin filaments and induce the polymerization or reorganization of the host cell actin filaments near the foci,thus to promote the phagocytosis of the pathogen by host cell.Investigating the role of PLD activation in the infection will be significance for further understanding the molecular mechanism of pathogen-host cell interaction.

Objective To construct the eukaryotic expression plasmids of short hairpin RNA (shRNA) specific for mouse Bcl-2-assoeiated athanogene 1 (BAG-1) and to observe their inhibitory effects on the expression of BAG-1 gene in mouse melanoma B16FI0 ceils. Methods Plasmids named pRNAT-U6.1/Neo-BAG-1, were designed and constructed to target the mouse BAG-1 mRNA coding region. LipofectaminTM 2000 was used to transfect plasmids into BI6F10 cells. Negative plasmid-transfected and tmtransfected B16F10 cells served as negative and blank controls respectively. Forty-eight hours following transfection, G418 was used to select the resistant cells. The mRNA and protein expression of BAG-1 gene was measured by reverse transcription-PCR and Western blot respectively about 1 month after the transfection. Results The eukaryotic expression plasmids, pRNAT-U6.1/Neo-BAG-1, were constructed, and verified by restriction enzyme digestion and DNA sequencing. The transfection rate in B16F10 cells was 20% -30%. Compared with the blank control, the mRNA and protein expression of BAG-1 in BI6FI0 cells was significantly inhibited by BAG-1 shRNA (both P<0.05), and the inhibition rates were (77±4)% and (62 ±2)%, respectively. Conclusions These results indicate that the eukaryotic expression vectors containing shRNA against BAG-1 gene, pRNAT-U6.1/Neo-BAG-1, are successfully constructed, and can significantly inhibit the expression of BAG-1 gene in mouse melanoma B16F10 cells.

Objective To investigate the pathogenesis of gallbladder chaotic dynamics after partial gastrec-tomy. Methods 140 cases operated by partial gastrectomy after 6 months were randomly examined, they in-cluded one group of 40 cases by Billroth type and the other 100 cases by Eiselsberg type. The ultrasonograph was applied to evaluate the function of gallbladder dynamics and radio-immunity method to determine the content of CCK at the time of having no food and 30 minutes after med. Results BV and RV of Eiselsberg group were bigger than Billroth Ⅰ obviously P<0.05. Gallbladder contraction rate displayed not well obvi-ously as too. The plasm level of CCK had no manifested distinctions in empty stomach cases of the 2 groups, but the increasing gradient plasm level of CCK in Billroth Ⅰ exceeded Eiselsberg type. Conclusions The pathogenesis of gallbladder chaotic dynamics after partial gastrectomy was correlated with the alterative type of partial gastrectomy, the reduction of CCK plasm level, the damage of anterior vagal trunk hepatic branches during the operations and so on led to the disorder of gallbladder emptying and induced cholecystolithiasis.

Objective To detective the carcinogenesis and operation principle of cyst canceration after internal drainage(ID) operation for congenital choledocal cyst (CCC).Methods The clinical data of 25 patients with cyst carcinoma after ID operation for CCC in the past 28 years were analysed retrospectively.Results The total canceration rate after internal drainage of CCC were 30.49%(25/82); after cystoduodenostomy was 35.29%(14/51),after cystojejunostomy was 22.58%(11/31), respectively. In the 25 cases, three of them were operated with Wipple operation , 4 with tumour resection plus biliary reconstrustion operation, 4 local resection with external drainage ,14 with external drainage only. Conclusions Internal drainage of CCC should be aborted becaus of the high canceration rate after the operation.
