OBJECTIVETo investigate the protective effect of Danxuetong injection (DXT, a combination of Danshen and Xueshuantong injections) against testicular ischemia-reperfusion injury following testis torsion/detorsion in rats.

METHODSThirty-two 4-week-old healthy male SD rats were randomly divided into four groups of equal number: sham operation, normal saline, single DXT injection, and successive DXT injection. The rat models of testicular ischemia-reperfusion injury were established by 2-hour 720-degree torsion/detorsion of the unilateral testis. At 6 weeks after modeling, the rats were killed and their testes were harvested for measure- ment of testicular coefficients, sperm counts, sperm motility, and the levels of total anti-oxidative capacity (T-AOC) , superoxide dismutase (SOD) , nitric oxide synthase (NOS) , and malondialdehyde ( MDA) in the testis tissue.

RESULTSCompared with the rats of the normal saline group, those of the single DXT injection and successive DXT injection groups showed significant increases in the testicular coefficient (0.11 ± 0.03 vs 0.35 ± 0.04 and 0.40 ± 0.06, P < 0.05), sperm count ([0.46 ± 0.10] vs [1.44 ± 0.50] and [3.00 ± 1.28] x10(9)/ml, P < 0.05), sperm motility ([13.63 ± 14.04] vs [39.63 ± 5.04] and [76.31 ± 3.67]%, P < 0.05), the activity of SOD (72.76 ± 5.58 vs 116.25 ± 8.83 and 133.20 ± 13.84, P < 0.05), and the level of T-AOC (5.58 ± 1.07 vs 13.34 ± 5.81 and 19.21 ± 5.69, P < 0.05), but a remarkable decrease in the content of MDA (42.38 ± 8.94 vs 20.94 ± 5.65 and 15.02 ± 1.03, P < 0. 05) in the injured testes.

CONCLUSIONDXT can effectively rid the testis tissue of oxygen free radicals, improve sperm count and motility by antioxidation, and protect the testis tissue of prepubertal rats against testicular ischemia-reperfusion injury after testis torsion/detorsion. It also has a protective effect on the contralateral testis, and successive injection has a better effect than single injection of DXT.

Objective: To observe the inhibitory effects of biotic royal jelly on the ascitic hepatoma cell H22. Methods: Mice bearing H22 tumor were fed on different types of royal jelly: No.1, 2 and 3. Their anti-tumor effects were observed in vivo. The general royal jelly and normal saline were observed as control. Results: Among these biotic royal jelly, the biotic royal jelly No.1 showed obvious tumor-inhibiting and survival-prolonging effects. In addition, it increased the number of WBC and augmented the amount of IL-2 and IFN-γ; the pathological study also indicated the denaturing and necrosis of most tumor cells with nuclei constraining and cell membrane rupturing, and large amount of lymphocytes and plasmacytes infiltrating around the mass. Conclusion: The No.1 biotic royal jelly has obvious anti-tumor effect, and it may take effects by inhibiting or killing tumor cells and improving the immunity of the host.

In order to study the value of sequential and quantitative analysis of chimerism in determination of optional time of donor lymphocyte infusion (DLI) and prediction of efficacy of DLI, six patients with leukemias who relapsed or failed of engraftment were treated with DLI. Serial and quantitative analyses of donor chimerism (DC) both prior to and following DLI were performed by multiplex PCR amplification of STR markers (STR-PCR) and capillary electrophoresis with fluorescence detection. The results showed that at the time of relapse or graft rejection, STR-PCR indicated the decreasing donor chimerism in all six patients, at levels ranging from 27.3% to 85.7%. The declining value of DC (<90%) was detected in four patients at 26 days before relapse or graft rejection diagnosed clinically. Therefore the decrease of value of DC can be identified the high risk of relapse or graft failure and can be used to guide DLI implementation at early stage. In this study the clinical response were seen in two patients, the value of DC in these patients increased with convertion to a predominant donor profile (>90%) or converted to stable FDC shortly after DLI, while in the patients without clinical response, the level of DC decreased persistently or declined after transient increase. Three patients without response received second DLI. It is concluded that the monitoring of chimerism is proved to be a valuable to determine the optional time point of DLI and to early evaluate the efficacy of DLI. Furthermore, it can present a rational basis for treatment of intensification in the patients who did not respond to first-line DLI treatment.

Laggera pterodonta is commonly used for treating influenza in Southwest China, especially in Yunnnan province. The main clinical effects of L. pterodonta include anti-influenza, anti-microbial, anti-inflammatory. To investigate the anti-influenza A (H1N1) virus effect of L. pterodonta, neutralization inhibition and proliferation inhibition tests were performed. MDCK culture method was used to observe the cytopathic effect (CPE) of extracts from L. pterodonta in inhibiting influenza A (H1N1) virus and haemagglutination titre of H1N1 virus in vitro. The culture medium were collected at 24 h, 48 h, 72 h, 96 h, and detected by Real time RT-PCR, in order to compare the effect of different extracts from L. pterodonta on in vitro proliferation of H1N1, virus. The result of neutralization inhibition test showed that hemagglutination titer of ethyl acetate extract were 8 times lower at 72 h; in proliferation inhibition test, hemagglutination titer of ethyl acetate extracts reduced by 2 and 4 times. According to the results of Real time RT-PCR test, the H1N1 inhibition ratio of ethyl acetate extract was 72.5%, while the proliferation inhibition ratio of ethyl acetate extract was 25.3%; as for petroleum ether extracts, the H1N1 inhibition ratio was 60.2%, while the proliferation inhibition ratio was 81.4%. In conclusion, both ethyl acetate extract and petroleum ether extract of L. pterodonta have significant neutralization and direct proliferation inhibition effects on influenza A virus.

OBJECTIVETo investigate the prevalence of JAK2V617F and MPLW515L/K mutation in patients with slightly elevated platelets (BPC) or hemoglobin (Hb) not meeting the criteria of polycythemia vera (PV) or essential thrombocythemia (ET).

METHODSGenomic DNA from bone marrow or blood mononuclear cells was screened with allele specific polymerase chain reaction (AS-PCR) for JAK2V617F and MPLW515L/K mutation. The history of thrombosis was assessed retrospectively by patients files.

RESULTSOf 30 patients, 14 (46.7%) were positive for the JAK2V617F mutation, none of them had the MPLW515L/ K. Five of these 14 patients had a history of thrombosis. Follow-up results were available in 22 patients. Among them, 12 patients with JAK2V617F mutation turned out to be MPD in 6-24 months; only 2 out of 10 patients without this mutation evolved to MPD.

CONCLUSIONJAK2V617F mutation could be one of the diagnosis criteria of early MPD. No MPLW515L/K expression was found in early MPD.

The importance of evidence-based medicine (EBM) in clinical acupuncture-moxibustion research is discussed in the paper. The application of EBM and problems in clinical acupuncture-moxibustion research are reviewed. It is put forward that thinking and assumptions of the combination of the evaluation of clinical effectiveness and EBM. The characteristics of acupuncture-moxibustion theory determine that the design of clinical research of acupuncture cannot completely apply the methods of EBM. Future efforts should be made to explore the integrated research design which is adhering to the guidelines of clinical practice of acupuncture. The features and advantages of traditional therapeutic practices should be preserved, and the advanced methods in EBM should be applied. It is great to improve the reliability and repeatability of clinical acupuncture-moxibustion research and to improve the standard and the evaluation system of clinical acupuncture.

PURPOSETo investigate the potential correlation between two different types of hip fractures and serum calcium levels.

METHODSWe consecutively studied 101 cases of femoral neck fracture and 95 cases of femoral inter- trochanteric fracture between January 2011 and December 2013. Fasting blood samples were taken and serum calcium measurements were performed respectively in three periods: the time of admission, postoperation, and discharge. Creatinine, alkaline phosphatase and albumin were also analyzed.

RESULTSConsidering the levels of serum calcium between two groups at the time of admission, post- operation and discharge, there was significant difference at admission and discharge (p <0.05), while there was no significant difference at the time of postoperation (p > 0.05). The magnitude of serum calcium fluctuation was larger in femoral neck group than femoral intertrochanteric group. Concerning alkaline phosphatase and albumin levels at admission, there was no significant difference between two groups (p > 0.05).

CONCLUSIONThe capability of reservation and restoration of serum calcium in patients with femoral neck fracture is better than that in patients with femoral intertrochanteric fracture. A low serum calcium level may be susceptible to femoral intertrochanteric fracture.

To evaluate soluble GM-CSF-Ralpha expression in patients with acute myeloid leukemia (AML) and its clinic significance, plasma concentration of solGM-Ralpha in de novo 66 patients with AML was detected by enzyme-linked immuno-sorbent assay, and the relationship between solGM-Ralpha levels and various clinical parameters was analyzed. The result showed that the levels of solGM-Ralpha in plasma of patients with AML were significantly higher than that in plasma of normal controls; the lowest level of solGM-Ralpha was found in plasma of patients with AML-M3 (3897.75 +/- 2651.43 pg/ml), the highest level of solGM-Ralpha was observed in plasma of patients with AML-M5 (9990.92 +/- 6325.43 pg/ml). Patients with high level of solGM-Ralpha were generally accompanied with a distinct clinical picture, including higher counts of white blood cell and myeloid precursors, as well as higher expression of CD34, CD95 and CD116 antigen. It is concluded that the high level of solGM-Ralpha in plasma of patients may suggest AML poor prognosis and play a role in pathogenesis of leukemia, the GM-CSF and its receptor solGM-Ralpha needs further study.
