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.

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.

Objective To improve the understanding of cutaneous intravascular natural killer/T-cell lymphoma (CIVNKTC). Methods Clinical data on five cases of CIVNKTC were collected. The histopathological feature, treatment and prognosis of CIVNKTC were retrospectively analyzed and discussed. Results Of the 5 patients, 1 was male and 4 were female. The age of onset ranged from 38 to 83 years (average, 56.2 years). All the patients presented with multiple plaques and nodules as the primary symptoms. Histopathological examination revealed vasodilatation in the dermis and subcutaneous tissue, as well as atypical lymphoid cells with large hyperchromatic nuclei containing 1-2 small nucleoli in dilated veins. Immunohistochemical studies of tumor cells showed positive staining for CD3ε, cytotoxic proteins (including T cell-restricted intracellular antigen-1, granzyme B and perforin)and Epstein-Barr virus(EBV)-encoded microRNA, but negative staining for cytokeratin, CD20, CD79a, CD4 and CD8. Furthermore, the tumor cells stained positive for CD56 in two patients. Among the 5 patients, only 2 received chemotherapy and the remaining received no treatment. During a 24-month follow-up, 4 patients died, and only 1 survived with the tumor. Conclusion CIVNKTC is a rare extranodal Hodgkin′s lymphoma with distinct histologic manifestations and immunophenotypes, rapid and aggressive clinical course, and poor prognosis.

Objective To construct the recombinant adeno-associated virus vector carrying cancerous inhibitor of PP2A (CIP2A)short hairpin RNA (shRNA)for preparation of high-titer viruses.Methods The small hairpin RNA of CIP2A (CIP2A shRNA)was designed,synthesized and cloned into pDC31 6-EGFP-U6 plasmid which was double digested by Bam HⅠ and Hin dⅢ.The resultant plasmid pDC31 6-EGFP-shRNA was confirmed and served as template to appraise primers.EGFP-CIP2A shRNA sequence was amplified by PCR,double digested with Eco RⅠand Sal Ⅰ and ligated to pSNAV2.0 plasmid digested with the same enzyme pair.pSNAV2.0-EGFP-CIP2A shRNA plasmid DNA was prepared,purified,identified and transfected into BHK-21 cells.BHK-21 cells expressing CIP2A shRNA (BHK-21/CIP2A-shRNA ) were obtained and subsequently infected with VGTC’s proprietary AAV packaging system to package the rAAV2-CIP2A shRNA.After purification,the functional and infectious virus was obtained and the titer of virus was detected.Real-time PCR and Western blot methods were used to detect the expression of CIP2A after infection with HepG2 cells,and the empty viral vector rAAV2-EGFP was used as control. Results A recombinant adeno-associated virus-2 vector carrying CIP2A shRNA was constructed successfully.The presence of the target sequence in the vector was confirmed by double enzyme digestion and sequencing.By transfecting the pSNAV2.0-EGFP-CIP2A shRNA plasmid into BHK-21 cells,BHK-21/CIP2A shRNA cells were infected with helper virus HSV1-rc/ΔUL2 to package the rAAV2-CIP2A shRNA to obtain a functional and infectious virus.The titer of the recombinant virus was 0.25×10 1 2 v.g./mL.The expression of CIP2A mRNA and screening value of 1×10 5 MOI effected HepG2 cells.Conclusion A high-titer recombinant adeno-associated virus-2 vector carrying CIP2A shRNA has been constructed successfully.

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 On the basis of the different shapes of upper airway(UA)obstruction and collapse characteristic of obstructive sleep apnea hypopnea syndrome(OSAHS), the effect of modified uvulopalatopharyngoplasty(UPPP)combined with coblation in OSAHS operations on patients with AHI≥20,which could be done selectively to patients with various or multiple UA obstructive sites, was explored. METHODS 30 patients of OSAHS were diagnosed and analysed by polysomnography(PSG)to have AHIs≥20. Based on the shapes of their UAs classified according to the degree of the shortened lateral and radial vectors,the UPPP was modified in two ways: either the lateral vector or the radial vector was amplified, or both could be amplified with coblation. All patients were analyzed by questionnaires(PSG)Muller's maneuver and oral cavity measurement pre-and 6 months post-operation. RESULTS 86.7 % of the patients showed a decrease of at least 25 % in AHI . Velopalatal insufficiency never occurred. CONCLUSION The modified-UPPP combined with coblation can be used selectively on patients based on their UA shapes.
