OBJECTIVETo compare the efficacy difference of analgesia and detumescence on ankle sprain among acupuncture at Xiaojie point combined with tendon regulation manipulation, acupuncture at Xiaojie point and tendon regulation manipulation.

METHODSSixty cases of ankle sprain were randomized into a combined therapy group, a Xiaojie point group and a tendon-regulation manipulation group, 20 cases in each one. The combined therapy of acupuncture at Xiaojie point and tendon regulation manipulation, the acupuncture at Xiaojie point and the simple application of tendon-regulation manipulation were applied respectively in the three groups, once a day, 3 treatments were required. The symptom score such as pain, ecchymosis, swelling and motor dysfunction and the total score were observed before and after treatment in the three groups. The different values of pain and swelling scores were compared before and after treatment in the three groups. The efficacy was compared among the groups.

RESULTSThe total effective rate was 100.0% (20/20) in each group. But the curative rate was 85.0% (17/20) in the combined group, 65.0% (13/20) in the Xiaojie point tion manipulation group. After treatment, the symptom scores of pain, ecchymosis, swelling and motor dysfunction and the total score were all improved as compared with those before treatment in the three groups (P < 0.01, P < 0.05). The pain score in either the combined therapy group or Xiaojie point group was lower than that in the tendon-regulation manipulation group after treatment (0.20 -/+ 0.41, 0.15 +/- 0.37 vs 0.60 +/- 0.50, both P < 0.05). Swelling score in the Xiaojie point group was different significantly from that in the tendon-regulation manipulation 0.49 vs 06.4 vs. 20+0.41, P < 0.05).

This study is to investigate the effect of the effective components group of Xiaoshuantongluo (XECG) on neuronal injury induced by oxygen-glucose deprivation (OGD) in primary cortical cultures isolated from SD rat cortex at day 3 and the possible mechanism. Cells were divided into control group, OGD model group and XECG group (1, 3 and 10 mg x L(-1)). The cell viability was assessed with MTT assay and the LDH release rate was measured by enzyme label kit. The cell apoptosis was analyzed using Hoechst staining. RT-PCR was applied to detect the mRNA levels of JAK2 and STAT3. Western blotting was used to detect the expressions of Bcl-2, Bax, p-JAK2 and p-STAT3 proteins. Results showed that XECG resulted in an obvious resistance to oxygen-glucose deprivation-induced cell apoptosis and decrement of cell viability, decrease the cell LDH release rate. XECG could adjust the expression of Bcl-2 and Bax proteins and increase Bcl-2/Bax ratio, up-regulate the expression of p-JAK2 and p-STAT3. In conclusion, XECG could protect against the neuronal injury cells exposed to OGD, which may be relevant to the promotion of JAK2/STAT3 signaling pathway, and impact the expression of Bax and Bcl-2.

Objective:To explore influence of multi-stage psychological intervention on long-term prognosis of patients with coronary heart disease(CHD)undergoing revascularization therapy.Methods:A total of 160 CHD patients, who suffered from depression after revascularization in our hospital,were selected.According to random number ta-ble,they were randomly and equally divided into routine psychological nursing group and multi-stage psychological nursing group,both groups were followed up for two years.Scores of self-rating anxiety scale(SAS),self-rating de-pression scale(SDS),Gensini score and incidence rate of main adverse cardiovascular events(MACE)were com-pared between two groups at enrollment and two years after enrollment.Results:Compared with enrollment,two years later,all scores significantly reduced in two groups(P=0.001 all);compared with routine psychological nurs-ing group,there were significant reductions in scores of SAS[(65.74 ± 3.95)scores vs.(61.13 ± 3.87)scores],SDS [(70.14 ± 5.69)scores vs.(65.59 ± 5.70)scores]and Gensini[(40.33 ± 4.30)scores vs.(35.14 ± 3.61)scores]in multi-stage psychological nursing group,P=0.001 all;Incidence rate of MACE in multi-stage psychological nursing group was significantly lower than that of routine psychological nursing group(13.75% vs.31.25%,P=0.008). Conclusion:Multi-stage psychological intervention can significantly relieve anxiety and depression state,reduce inci-dence of major adverse cardiovascular events in patients with coronary heart disease after revascularization.

Recently, we have reported a new gfp gene isolated from Aequorea macrodactyla. The protein purified from expressed E. coli exhibited an excitation peak at 476 nm and an emission peak at 496 nm. However, the drawback of only maturing to fluorescence at low temperature limited its applications. In this paper, we further describe twelve mutants of GFPxm. Seven mutants produced enhanced fluorescence when expressed in E. coli at higher temperature (37 degrees C). After six hours of induction at 25 degrees C, 32 degrees C and 37 degrees C respectively, the relative fluorescent intensities of GFPxm16, GFPxm18 and GFPxm19 were higher than that of EGFP, moreover GFPxm16 and GFPxm163 could preserve high fluorescent intensity even expressed at 42 degrees C. Four mutants of the seven could reach high expression level in three kind of mammalian cells. Another 6 mutants had red-shift of excitation-emission maxima, and longest excitation-emission maxima were 514nm and 525nm. Another three mutants had two excitation peaks, and one mutant had only one UV-excitation peak. The most exciting result is the mutant of OFPxm with orange color. The mutant has an excitation peak at 509 nm and an emission peak at 523nm. 523nm is yellowish green but the protein is orange observed by eyes. The mutant could reach high expression level and matured at higher temperature but the fluorescent intensity was comparatively low because of low quantum yield.

OBJECTIVETo study the impact of neoadjuvant therapy on lymph nodes retrieval in locally advanced mid-low rectal carcinoma.

METHODSData collected from 120 patients with locally advanced mid-low rectal cancer (T2-4 and/or N1-2M0) treated from January 2005 to June 2008 was investigated. The patients were divided into two groups: the study group (n=54) was treated with neoadjuvant therapy (preoperative radiation with a total dosage of 50 Gy and synchronous 5-Fu-based chemotherapy) followed by radical tumor resection 4-6 weeks after;the control group (n=66) underwent primary surgery without neoadjuvant therapy. The clinical stage was evaluated before and after neoadjuvant therapy. The total lymph nodes yields, as well as the tumor-positive lymph nodes of each resected specimen was compared between the two groups statistically.

RESULTSClinical downstage was achieved in 30 cases (56%) in study group after neoadjuvant therapy. The number of total lymph nodes and positive lymph nodes harvested from each resected specimen in the control group were 14+/-7 and 2.2+/-3.7, meanwhile those were 9+/-6 and 0.7+/-2.4 in study group, which were all significantly lower than those in control group (P<0.01).

CONCLUSIONSPreoperative radiotherapy combined with chemotherapy can downstage the tumor and reduce the retrieval rate of total lymph nodes and positive lymph nodes in locally advanced rectal cancer. It is necessary to retrieve as many lymph nodes as possible for it has some prognostic significance for the patients.

Objective To investigate the prevalence of anti-hepatitis E virus (HEV) and genotypes of hepatitis E virus in 8 species of animals including swine, cattle, sheep, horse, donkey, dog, chicken and duck in the suburb of Beijing. Methods Serum samples were collected from the 8 species of animals, and fecal samples of younger swine were collected from 2 stock farms. Anti-HEV was detected by Double Antigen Sandwich Assay. HEV RNA from fecal samples was detected by a reverse transcription nested polymerase chain reaction (RT-nPCR). Parts of the PCR products were cloned and sequenced. The swine HEV sequences were analyzed genetically. Results The positive rates of anti-HEV in serum specimens of swine, cattle, horse, donkey, sheep, dog, duck and chicken were 80.43%(481/598), 15.02%(52/346), 14.29%(40/280) ,0(0/26) ,9.88%(33/334), 0(0/ 21) ,3.03% (7/231) and 2.53%(8/316), respectively. The anti-HEV prevalence of adult swine(≥6 months)and younger swine(≤3 months)were 87.86%(369/420)and 62.92%(112/178)respectively. 74 of 111 (66.67% ) pig faces were positive for HEV RNA. Sequence analysis on these positive samples showed that there were 6 groups of HEV designated as bjsw1, bjsw2, bjsw3, bjsw4, bjsw5 and bjsw6. The 6 strains of HEV shared 94.5%-99.6% sequence identity of partial HEV ORF2 nucleotide with each other. The identities of HEV ORF2 nucleotide sequences between the 6 strains and genotype 1, 2, 3 and 4 were 75.6%-78.6% , 75.6%-76.2%, 77.1%-80.7% and 83.7%-94.5%, respectively. The sequence identity between the 6 strains and human HEV genotype 4d was 90.0%-94.5% . Conclusion HEV infection was seen in swine, cattle, horse, sheep, duck and chicken in the suburbs of Beijing. The anti-HEV positive rate appeared the highest in swine and the lowest in dog and donkey. The six strains of HEV isolated from younger swine belonged to genotype 4d.

OBJECTIVETo investigate the expressions of STAT5 phosphorylation in CD34(+)CD38(-)CD123(+) bone marrow cells of the patients with myelodysplastic syndromes (MDS), and then evaluate the level of activation of STAT5 associated with cell proliferation in MDS clone cells.

METHODSThe bone marrow mononuclear cells (BMMNC) were extracted from 36 MDS patients and 14 normal controls. The mean fluorescence intensities (MFI) of phosphorylated STAT5(P-STAT5) in CD34(+)CD38(-)CD123(+) and CD34(+)CD38(-)CD123(-)cells, with or without the stimulation of 10 U/ml EPO, were examined by flow cytometry (FCM).

RESULTSWithout stimulation, the P-STAT5 MFI in CD34(+)CD38(-)CD123(+) cells of low/high risk MDS patients was 113.71 ± 67.22/173.05 ± 102.78, which was significantly higher than that of CD34(+)CD38(-)CD123(-) cells (58.84 ± 27.51/68.99 ± 50.42, P < 0.01, P < 0.05) and the normal controls CD34(+)CD38(-)CD123(-) cells (63.06 ± 21.06, P < 0.05), there was no significant difference between the CD34(+)CD38(-)CD123(-) cells of MDS patients and the normal control CD34(+)CD38(-)CD123(-) cells; With the EPO stimulation, the P-STAT5 MFI in CD34(+)CD38(-)CD123(+) cells of low/high risk MDS patients was 144.04 ± 58.11/239.45 ± 152.05, which was significantly higher than that of CD34(+)CD38(-)CD123(-) cells (68.41 ± 25, 10/64.21 ± 23.43, P < 0.01) and the normal controls CD34(+)CD38(-)CD123(-) cells (75.21 ± 27.02, P < 0.01), there was no significant difference between the CD34(+)CD38(-)CD123(-) cells of MDS patients and the normal control CD34(+)CD38(-)CD123(-) cells; The P-STAT5 MFI in the CD34(+)CD38(-)CD123(+) cells of low/high risk MDS patients with or without EPO stimulation were 21.80/28.86, which was significantly higher than that of CD34(+)CD38(-)CD123(-) cells (7.42/5.50, P < 0.01, P < 0.05) and the normal controls CD34(+)CD38(-)CD123(-) cells (6.39, P < 0.05), there was no significant difference between the CD34(+)CD38(-)CD123(-) cells of MDS patients and the normal controls CD34(+)CD38(-)CD123(-) cells; There was no significant difference of P-STAT5 MFI with or without EPO stimulation and the increased P-STAT5 MFI between the CD34(+)CD38(-)CD123(+) cells of low and high risk MDS.

CONCLUSIONSTAT5 associated with cell proliferation was activated in CD34(+)CD38(-)CD123(+) bone marrow cells in MDS, which had more significant reactions to EPO than CD34(+)CD38(-)CD123(-) cells, indicating that CD34(+)CD38(-)CD123(+) bone marrow cells might be the real malignant MDS clone cells in MDS.

OBJECTIVETo investigate the expression of Notch1 on the membrane of bone marrow CD38(+)CD138(+) plasma cells in the patients with multiple myeloma (MM), and explore the importance of Notch signaling pathway in the formation and progression of MM.

METHODSThirty three MM patients and 15 healthy controls were enrolled in this study. The expression of Notch1 on the membrane of bone marrow CD38(+)CD138(+) and CD38(+)CD138(-) plasma cells were analyzed by flow cytometry. The clinical data of MM patients were also analyzed.

RESULTSThe ratio of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients was (60.21 ± 25.06)% which was significantly higher than those of CD38(+)CD138(-) plasma cells of MM patients (39.84 ± 18.94)% (P = 0.000) and controls (38.34 ± 19.39)% (P = 0.004). There was no statistical difference between the two latter groups (P > 0.05). The expression of Notch1 on CD38(+)CD138(+)plasma cells from 24 newly diagnosed MM patients was correlated to the level of malignant plasma cells in there bone marrow (r = 0.914, P = 0.000), serum level of lactate dehydrogenase (LDH) (r = 0.754, P = 0.007), and β(2)-MG(r = 0.716, P = 0.013). The ratio of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients who had renal dysfunction was correlated to their abnormal serum creatinine levels. The expression of Notch1 on CD38(+)CD138(+) plasma cells from 17 MM patients who received VD (bortezamib and dexamethasone) chemotherapy was correlated to the ratio of plasma cell reduction after the first VD chemotherapy (r = 0.842, P = 0.000).

CONCLUSIONThe expression of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients was significantly higher than those of CD38(+)CD138(-) plasma cells of MM patients and controls. Notch1 overexpressed plasma cells were sensitive to the early VD therapy, and correlated to the progression and long term outcome of MM.

This study was purposed to investigate the expressions of miR-21, miR-155 and miR-210 in plasma of patients with lymphoma, and explore their role played in diagnosis, evaluation of chemotherapy effect and prognosis of lymphoma. The expressions of miR-21, miR-155 and miR-210 were assayed by RT-PCR in plasma of 54 cases of lymphoma, 10 cases of lymphonode inflammation and 27 cases of normal controls. The results indicated that the expressions of miR-21, miR-155 and miR-210 in plasma of lymphoma patients were higher than those of control group and lymphonode inflammation group (P < 0.05). The expressions of miR-21 and miR-210 in plasma of control group and lymphonode inflammation group had no significant differences (P > 0.05). The expression of miR-21 in plasma of lymphoma patient group significantly correlated with their serum LDH level. The expressions of miR-21 and miR-210 in plasma of previously untreated lymphoma patient group were higher than those of the patients treated for 6 or more courses (P < 0.05). The diagnostic accuracy of miR-21, miR-155 and miR-210 used for lymphoma patients was 56, 65, 48 respectively, and reached to 83 when combined three of them. It is concluded that the expressions of miR-21, miR-155 and miR-210 in plasma of lymphoma patients were significantly higher. Detection of these 3 miRNA in plasma of patients can contribute to the clinical diagnosis, treatment and prognosis evaluation of lymphoma.
