Objective To investigate the clinical therapeutic effect of filiform fire needling on tennis elbow.Method Eighty patients with tennis elbow were randomly allocated to a filiform fire needling group of 30 cases, a block group of 20 cases and an electroacupuncture group of 30 cases. The treatment group received. Pain severity was scored using the VAS after one and two weeks and one month of treatment. The therapeutic effects were evaluated and compared after one month of treatment.Result The total efficacy rate was 93.3% in the filiform fire needling group, 60.0% in the block group and 50.0% in the electroacupuncture group; there was a statistically significant difference among the three groups (P<0.05). There was a statistically significant difference between the filiform fire needling and block groups (P<0.05) and between the filiform fire needling and electroacupuncture groups (P<0.05) but no significant difference between the block and electroacupuncture groups (P>0.05). The VAS score decreased significantly in the block group (P<0.05) but did not in the filiform fire needling and electroacupuncture groups (P>0.05) after one week of treatment compared with before. The VAS score decreased significantly in the filiform fire needling and block groups (P<0.05) but did not in the electroacupuncture group (P>0.05) after two weeks of treatment compared with before. There was no statistically significant posttreatment difference in the VAS score between the filiform fire needling and block groups (P>0.05) but there was such a difference between the filiform fire needling or block group and the electroacupuncture group (P<0.05). There was a statistically significant difference in the VAS score in the filiform fire needling and block groups (P<0.01) and also in the electroacupuncture group (P<0.05) between before and after one month of treatment. There was a statistically significant difference in the VAS score after one month of treatment between the filiform fire needling group and the block or electroacupuncture group (P<0.05) and between the block and electroacupuncture groups (P<0.05). The results of the study showed that filiform fire needling, local drug blockage and electroacupuncture all had clinically a better therapeutic effect on tennis elbow and a better improving effect on the symptoms in the patients. Filiform fire needling produced a marked therapeutic effect. Its effect was superior to those of block therapy and electroacupuncture.Conclusion Filiform fire needling is a definitely effective way to treat tennis elbow.

Multi-target drugs attract increasing attentions for the therapy of complicated neurodegenerative diseases. In this study, a computer-assisted strategy was applied to search for multi-target compounds by the pharmacophore matching. This strategy has been successfully used to design dual-target inhibitor models against both the acetylcholinesterase (AChE) and poly (ADP-ribose) polymerase-1 (PARP-1). Based on two pharmacophore models matching and physicochemical properties filtering, one hit was identified which could inhibit AChE with IC50 value of (0.337 +/- 0.052) micromol x L(-1) and PARP-1 by 24.6% at 1 micromol x L(-1).

Objective To investigate the relationship between cytokines and human graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods In 21 patients undergoing allo-HSCT,the plasma concentrations of cytokines[soluble interleukin 2 receptor(sIL-2R), interferon-gama (IFN-γ), transforming growth factor-betal (TGF-β1)] were measured by using sandwich enzyme-linked immunological assay (ELISA) and the gene expressions of three cytokines were analysed by using semi-quantitate reverse transcriptase-polymerase chain reaction(RT-PCR). Results The concentrations and gene expressions of sIL-2R and IFN-γin the patients with GVHD were significantly higher than those without GVHD (P <0.01), and they were higher in the patients with aGVHD than with cGVHD and without GVHD(P <0.05); the levels of TGF-β1 in the patients with GVHD were significantly declined(P <0.01), but in those without aGVHD were obviously increased(P <0.05). After effective treatment, unnormal sIL-2R, IFN-γand TGF-β1 expressions recovered to the levels before transplantation. A multivariate COX analysis showed sIL-2R and TGF-β1 are independent prognostic factors for GVHD (P<0.001). Conclusion Monitoring the changes of sIL-2R, IFN-γand TGF-β1 expression levels (especially sIL-2R and TGF-β1) might provide predictive markers for GVHD after allo-HSCT. The sensitivity between RT-PCR and ELISA for detecting cytokines expressions had no difference.

Dimethyl sulfide (DMS) has been historically recognized as a metabolite of the marine microorganism or a disgusting component for the smell of halitosis patients. In our recent study, DMS has been identified as a cytoprotectant that protects against oxidative-stress induced cell death and aging. We found that at near- physiological concentrations, DMS reduced reactive oxygen species (ROS) in cultured PC12 cells and alleviated oxidative stress. The radical-scavenging capacity of DMS at near-physiological concentration was equivalent to endogenous methionine(Met)-centered antioxidant defense. Methionine sulfoxidereductase A (MsrA), the key antioxidant enzyme in Met-centered defense, bound to DMS and promoted its antioxidant capacity via facilitating the reaction of DMS with ROS through a sulfonium intermediate at residues Cys72, Tyr103, Glu115, followed by the release of dimethyl sulfoxide (DMSO). MTT assay and trypan blue test indicated that supplement of DMS exhibited cytopro?tection against 6-hydroxydopamine and MPP + induced cell apoptosis. Furthermore, MsrA knockdown abolished the cytoprotective effect of DMS at near- physiological concentrations. The present study reveals new insight into the potential therapeutic value of DMS in Parkinson disease.

OBJECTIVETo study the changes in diaphragmatic function and gene expressions of calcium regulatory proteins in diabetic rats and explore the mechanism of diaphragm dysfunction in diabetes mellitus.

METHODSSD rats were randomly divided into normal control group and diabetic (induced by intraperitoneal STZ injection) group. After 4 and 8 weeks, the body weight and diaphragm to body weight ratio were measured, and the activities of succinic dehydrogenase (SDH) in the diaphragm and blood glucose were assayed. The diaphragm contractility was assessed and the alterations of diaphragm ultrastructure were observed. RT-PCR was used to detect the changes in sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) and phospholamban (PLB) mRNA expressions in the diaphragm.

RESULTSThe diabetic rats showed a significant weight loss with a lowered diaphragm to body weight ratio (P<0.01) and SDH activity (P<0.01). The peak twitch tension and maximum tetanic tension of the diaphragm were significantly lowered and the time to peak contraction and half relaxation time significantly prolonged (P<0.01) in the diabetic rats, which also exhibited a lowered tetanic force in response to stimulus (P<0.01). Transmission electron microscopy revealed obvious ultrastructural changes of the diaphragm in diabetic rats. RT-PCR showed significantly decreased SERCA and increased PLB mRNA expressions in diabetic rat diaphragm (P<0.01), and these changes intensified with time (P<0.01).

CONCLUSIONDiabetes can cause impairment of diaphragmatic ultrastructure, mitochondrial injuries, and lowered SDH activity and ATP production. Decreased SERCA and increased PLB mRNA expressions in diabetes result in reduced Ca(2+) uptake by the diaphragm sarcoplasmic reticulum to induce diaphragm dysfunction.

OBJECTIVE: To study the correlation of daily living activities with location and severity of trau- matic brain injury (TBI) and to provide a theoretical basis for improving the accuracy of expert opinion. METHODS: Five hundred and one cases of patients with TBI were selected. Detailed records included following: pre-injury situation, location and severity of injury, treatment and education. Daily living activi- ties scale (Barthel index) was applied to test the subjects' daily living activities. The relevance among location and severity of TBI and Barthel index was statistically analyzed. RESULTS: In mild TBI group, there was no significant difference in Barthel index among each location (P>0.05). In moderate TBI group, there were significant differences in Barthel index between subarachnoid hemorrhage and cerebral lobe injury, also between parietal, occipital lobes injury and frontal lobe injury, parietal, occipital lobes injury and temporal lobe (P<0.05), respectively, whereas no significant difference in Barthel index between frontal lobe injury and temporal lobe injury (P>0.05). In severe TBI, there were significant differences in Barthel index between every two different locations (P<0.05). CONCLUSION There is some correlation between the location of TBI and Barthel index, which provides an important reference value for analyzing and determining daily living activities after TBI.

OBJECTIVETo explore the expression and clinical significance of Semaphorin4D (Sema4D) mRNA in peripheral blood lymphocyte, Sema4D on platelet surface, soluble Sema4D (sSema4D) in plasma in patients with cerebral infarction.

METHODSTaking 299 patients with cerebral infarction as the case group while 195 healthy adults as the control group. The mRNA expression of Sema4D was detected by Real-time PCR, and Sema4D expression on platelet by flow cytometry, sSema4D by ELISA. Then, the expression of Sema4D on platelet surface and the concentration of sSema4D in plasma of the 195 selected patients following 2 weeks' treatment were tested.

RESULTSThe expression of Sema4D mRNA significantly increased in the case group \[(2.23, 2.66)×10(4) IU/ml\] than in the control group \[(0.49, 0.53)×10(4)IU/ml\] (P < 0.01). The level of Sema4D on platelet surface in the case group (191.62 ± 46.56) significantly decreased than in the control group (303.33 ± 112.66) (P < 0.01). But the concentration of sSema4D in plasma in the case group \[(1.34 ± 0.56) µg/L\] was obviously higher than in the control group \[(0.61 ± 0.31) µg/L\] (P < 0.01). The expression of Sema4D on platelet was obviously relevant with the concentration of sSema4D in plasma in the case group with the correlation coefficient as 0.328 (P < 0.01). The expression of Sema4D on platelet obviously peaked up following 2 weeks' routine therapy in the case group, which was close to that in the control group. Meanwhile the concentration of sSema4D in plasma was downward corrected to the normal in the case group.

CONCLUSIONThe increased expressions and plasma levels, and reduced expressions on platelet of Sema4D in acute period, which returned to normal 2 weeks after treatment in the case group may be related to the occurrence of acute cerebral infarction, reflecting the development process of cerebral infarction.

BACKGROUNDInfections caused by gram-negative bacteria (GNB) often lead to high mortality in common clinical settings. The effect of traditional antibiotic therapy is hindered by drug-resistant bacteria and unneutralizable endotoxin. Few effective methods can protect high risk patients from bacterial infection. This study explored the protection of adeno-associated virus 2 (AAV2)-bacteriacidal permeability increasing protein 700 (BPI(700))-fragment crystallizable gamma one 700 (Fc gamma1(700)) chimeric gene transferred mice against the minimal lethal dose (MLD) of E. coli and application of gene therapy for bacterial infection.

METHODSAfter AAV2-BPI(700)-Fc gamma1(700) virus transfection, dot blotting and Western blotting were used to detect the target gene products in Chinese hamster ovary-K1 cells (CHO-K1cells). Reverse transcription-polymerase chain reaction and immunohistochemical assay were carried out to show the target gene expression in mice. Modified BPI-enzyme linked immunosorbent assay was used to identify the target gene products in murine serum. The protection of BPI(700)-Fc gamma1(700) gene transferred mice was examined by survival rate after MLD E. coli challenge. Colony forming unit (CFU) count, limulus amebocyte lysate kit and cytokine kit were used to quantify the bacteria, the level of endotoxin, and proinflammatory cytokine.

RESULTSBPI(1-199)-Fc gamma1 protein was identified in the CHO-K1 cell culture supernatant, injected muscles and serum of the gene transferred mice. After MLD E. coli challenge, the survival rate of AAV2-BPI(700)-Fc gamma1(700) gene transferred mice (36.7%) was significantly higher than that of AAV2-enhanced green fluorescent protein (AAV2-EGFP) gene transferred mice (3.3%) and PBS control mice (5.6%). The survival rate of AAV2-BPI(700)-Fc gamma1(700) gene transferred mice treated with cefuroxime sodium was 65.0%. The bacterium number in main viscera, the levels of endotoxin and proinflammatory cytokine (tumor necrosis factor-alpha and interleukin-1beta) in serum of the AAV2-BPI(700)-Fc gamma1(700) gene transferred mice were markedly lower than that of PBS control mice (P < 0.01).

CONCLUSIONSAAV2-BPI(700)-Fc gamma1(700) gene transferred mice can resist MLD E. coli infection through expressing BPI(1-199)-Fc gamma1 protein. Our findings suggested that AAV2 mediated BPI(700)-Fc gamma1(700) gene delivery could be used for protection and treatment of clinical GNB infection in high-risk individuals.
