OBJECTIVETo investigate the semen quality of cancer patients and search for a better way of sperm cryopreservation for them.

METHODSWe retrospectively analyzed the quality of the semen from 43 cancer patients under cryopreservation in the Sperm Bank of Zhejiang Province, and compared the semen parameters between the cancer patients and 248 normal donors as well as between the testicular cancer cases (n=22) and non-testicular cancer cases (n=21).

RESULTSThe cancer patients exhibited significantly lower semen quality than the normal donors as in sperm concentration (60.90 x 10(6)/ml vs 74.27 x 10(6)/ml), progressive motility (41.07% vs 51.79%), and recovery rate (49.98% vs 57.33%) (all P <0.05). Furthermore, the progressive sperm motility and sperm recovery rate after freezing were significantly decreased in the testicular cancer cases (15.68% and 42.81%) than in the non-testicular cancer cases (28.36% and 57.53%) (both P <0.05).

CONCLUSIONSemen quality declines in cancer patients, and therefore early sperm cryopreservation is essential for them. Due to the poor sperm motility and recovery rate of testicular cancer patients after freezing, further investigation is required on the improvement of sperm cryopreservation methods.

Aim To evaluate the effects of pantoprazole on various experimental acute ulcer inrats and mice. Methods The model of a gastric ulcer of rats or mice was caused bystree- induced ulcer and ligatel pylurus-induced ulcer. Results & Conclusions At adose of 5, 10, 20 mg? kg-1 of Pantoprazole can markedly decrease the ulcer index ofstree-induced ulcer. Pantoprazole(4, 8, 16 mg? kg -1 ) significantly decrease the areaof ligated pylorus-induced gastric ulcer. It was also found that pantoprazole caninhibit the output of basic gastric acid.

This study investigated the effect of arctigenin (Arc) on the cell activation, cytokines expression, proliferation, and cell-cycle distribution of mouse T lymphocytes. Mouse lymphocytes were prepared from lymph node and treated with Phorbol-12-myristate-13-acetate (PMA)/Ionimycin (Ion) and/or Arc. CD69, CD25, cytokines, proliferation and cell cycle were assayed by flow cytometry. The results showed that, at concentrations of less than 1.00 micromol x L(-1), Arc expressed non-obvious cell damage to cultured lymphocytes, however, it could significantly down-regulate the expression of CD69 and CD25, as well as TNF-alpha, IFN-gamma, IL-2, IL-4, IL-6 and IL-10 on PMA/Ion stimulated lymphocytes. At the same time, Arc could also inhibit the proliferation of PMA/Ion-activated lymphocytes and exhibited lymphocyte G 0/G1 phase cycle arrest. These results suggest that Arc possesses significant anti-inflammatory effects that may be mediated through the regulation of cell activation, cytokines expression and cell proliferation.

OBJECTIVETo investigate the role of CD40 ligand (CD40L) in dendritic cells (DC) of CEA transgenic mice and to evaluate the specific cellular immunity induced by activated DC.

METHODSBone marrow cells of the CEA transgenic mice were used to generate immature dendritic cells under the condition of GM-CSF and IL-4. CD40L was added to activate dendritic cells into mature phenotype. Dendritic cells cancer vaccine was pulsed with CEA526-533 peptide which made the vaccine specific for cancer immunity. The immunophenotype molecules were identified by flow cytometry. The cytokines produced by cells were determined by ELISA. T cells proliferation was measured by (3)H-thymidine essays.

RESULTSImmunophenotype molecules expressions of CD40L-activated dendritic cells were significantly higher than those in control group. IL-12 secretion by CD40L-activated dendritic cells was (937.81+/-51.99) pg/10(6) DC, significantly higher than that in control group [(83.06+/-8.58) pg/10(6) DC, P<0.01]. CD8(+) T cells proliferation induced by CD40 L-activated dendritic cells was stronger as compared to control group (P<0.05), and the secretion of IFN-gamma was(33.900+/-4.550) ng/L, significantly higher than that in control group [(5.226+/-0.460) ng/L, P<0.01]. Splenocytes proliferation induced by CD40 L-activated dendritic cells was stronger as compared to control group (P<0.01), and the secretion of IFN-gamma was (69.802+/-11.407) ng/L, significantly higher than that in control group [(2.912+/-0.562) ng/L, P<0.01].

CONCLUSIONThe method of using CD40L to stimulate bone marrow-delivered dendritic cells promotes the maturation and activation of dendritic cells, which enhances the cellular immunity in CEA transgenic mice.

OBJECTIVETo objectively assess the influence of Xiaoliu Baofei Pill (XBP) combined with chemotherapy on quality of life (QOL) of patients with stage III-IV non-small cell lung cancer (NSCLC).

METHODSForty NSCLC patients were equally randomized into 2 groups, the treated group treated with XBP plus chemotherapy, and the control group treated with chemotherapy alone. Patients' QOL was assessed by Functional Assessment of Cancer Therapy (FACT-L) before and after treatment.

RESULTSThe scores of the physical condition in the treated group was relatively stable while it lowered significantly as time went by in the control group, significant difference was shown as compared with before treatment and with that in the treated group at the same time points (P < 0.05); scores of the mood condition, the function conditions and additional concerned condition were improved gradually from the 3rd collection in the treated group, but decreased in the control group, although some improvement of mood and function conditions had revealed temporarily in the early stage of treatment. Comparison between groups showed significant difference (P < 0.05). Besides, no significant change was found in domains of patient-doctor relation and society/family condition in both groups.

CONCLUSIONXBP combined with chemotherapy can obviously improve the QOL of advanced NSCLC patients.

Objective To explore the value of dual energy CT displaying knee joint torn posterior cruciate ligament (PCL). Methods Ten cases with single knee joint torn PCL were scanned by 1.5 TMR and dual energy CT. By the use of postprocessing technique of muhiplanar reformation (MPR) and volume rendering technique (VRT), the CT value,length,thickness of PCL were assessed by paired t test respectively. Results MPR and VRT clearly displayed the PCL. The CT value of the patient sides and normal sides were(60.10±3.21), (72.98±7.35) HU(t=4.33,P=0.006), the length were(4.42±0.56),(4.14±0.49) cm (t=-1.20,P=0.285), the thickness of the attachment site and middle sire were (0.88±0.19), (0.58±0.10), (0.38±0.12) cm and (0.43±0.07), (0.39±0.03), (0.43±0.12) cm (t=-6.89,P=0.001;t=-4.38,P=0.007;t=0.85,P=0.587) respectively. Conclusion Dual energy CT can demonstrate clearly the ligament with three-dimension display,and may provide important information for diagnosis and per-surgical evaluation.

OBJECTIVETo observe the effect of Xiaoyao Nose Drops (XYND) in stopping episode of migraine.

METHODSAdopted was the randomized double-blinded placebo-controled method, with the 126 patients equally assigned to two groups, the treated group treated with XYND and the control group with placebo, and the therapeutic course was 30 days for all. The clinical total effective rate and effect in alleviating headache were observed. And hemorrheological parameters as well as the blood flow of the anterior cerebral artery (ACA), median cerebral artery (MCA) and posterior cerebral artery (PCA) were measured before and after treatment.

RESULTSThe clinical total effective rate and headache alleviating rate in the treated group were 93.33% and 96.67% respectively, while those in the control group were 18.33% and 20.00% respectively, and comparison between the two groups showed significant difference (all P < 0.01). The blood viscosity (high, middle and low shear), plasma viscosity and fibrinogen got lowered significantly in the treated group after treatment, showing significant difference in comparison either with those before treatment or with those in the control group after treatment (P < 0.05 or P < 0.01). The velocity of blood flow in all cerebral arteries lowered significantly, also showing significant difference in comparison either with those before treatment or with those in the control group after treatment (P < 0.05 or P < 0.01).

CONCLUSIONXYND is effective in stopping the headache of patients with migraine, and worth applying in clinical practice.
