OBJECTIVESTo observe the change of erythropoietin (EPO) in patients of hypogonadism who received androgen replacement treatment and explore the mechanism of androgen-induced increase of red blood cells and haemoglobin.

METHODSEight patients with Klinefelter's syndrome, divided into two groups, received TU intramuscular injections of 500 mg or 1000 mg dose, respectively. After three months, seven patients received the second injection of crossover dose. Testosterone levels in serum were measured with RIA before and after the injections treatment. RBC count, impacted volume of blood cells and haemoglobin concentration were measured before treatment and 4, 8 weeks after treatment. At the same interval, EPO levels were measured with ELISA method.

RESULTSDevelopment of the secondary sex characters was improved in all patients after the TU injection. Serum testosterone levels raised significantly and reached the peak one week after the injections. Effective level of testosterone lasted for over 6 weeks. RBC count, impacted volume of blood cells and haemoglobin increased at different degrees after TU injections, but these changes were not significant in statistic(P < 0.05). The increased levels remained for 8 weeks. EPO levels were elevated significantly (P < 0.01 or 0.05) after the TU injection(Pbat > 0.05). The second injection could still make the EPO level go up.

CONCLUSIONSAndrogen replacement treatment can increase the EPO levels in patients of hypogonadism, which is one of the mechanism of RBC production increase.

OBJECTIVETo investigate the effect of X-rays on expression of caspase-3 and p53 protein in EL-4 cells and its implications in induction of apoptosis and polyploid cells.

METHODSMouse lymphoma cell line (EL-4 cells) was used. Fluorescent staining and flow cytometry analysis were employed for measurement of protein expression, apoptosis, cell cycle, and polyploid cells.

RESULTSThe expression of caspase-3 protein increased significantly at 8 h and 12 h, compared with that of sham-irradiated control (P<0.05, respectively) and the expression of p53 protein increased significantly at 2, 4, 8, 12, and 24 h, compared with that of sham-irradiated control (P<0.05-P<0.01) in EL-4 cells after 4.0 Gy X-irradiation. Apoptosis of EL-4 cells was increased significantly at 2, 4, 8, 12, 24, 48, and 72 h after 4.0 Gy exposure, compared with that of sham-irradiated control (P<0.05-P<0.001). G2 phase cells were increased significantly at 4, 8, 12, 24, 48, and 72 h (P<0.05-P<0.001). However, no marked change in the number of 8 C polyploid cells was found from 2 to 48 h after 4.0 Gy exposure.

CONCLUSIONThe expressions of caspase-3 and p53 protein in EL-4 cells are induced by X-rays, which might play an important role in the induction of apoptosis, and the molecular pathway for polyploid formation might be p53-independent.

OBJECTIVETo observe and compare the protective effect of garlic oil against carbon tetrachloride (CCL)-induced acute liver injury.

METHODSThe experiments include 4 preventive groups and 2 therapeutic groups. In every preventive and therapeutic group, the mice were randomized into 6 groups with 15 each, including one negative control group, one solvent control group, one CCl4 model group and 3 garlic oil groups (25, 50, and 100 mg/kg body weight). Before given a single gavage of CCl4 (80 mg/kg), the mice were pretreated with garlic oil by gavage in preventive group 1 (30 days, once daily), preventive group 2 (5 days, once daily), preventive group 3 (ahead of 2 h, once), preventive group 4 (immediately, once) or the vehicle (corn oil, 10 ml/kg) in solvent control group. In therapeutic groups, the mice were gavaged garlic oil 2 h (once, in therapeutic 1) or for 5 days (once daily, in therapeutic 2) after administration CCl. After 24 h of the last administration, blood was collected and centrifuged at 2500 r/min at 4 degrees C for 10 min, and serum was removed to measure ALT and AST activities. The liver was dissected, weighed to calculate the liver coefficient (relative liver weight). At the same time, the liver samples were studied by histological examinations.

RESULTSCompared with negative group, the liver coefficient and the activities of ALT and AST in serum of model group were increased remarkably (P < 0.01). Compared with CCl model group, the liver coefficient and the activities of ALT and AST in serum were decreased significantly (P < 0.01) by garlic oil dose-dependently in each preventive group. Simultaneously, histological assessment showed that garlic oil effectively alleviated hepatocyte injuries induced by CCl4. Comparing the preventive effects of garlic oil in every group, it was better in preventive group 3 than others. However, all indexes and histological examinations in therapeutic group 1 did not show the difference with those of CCl4 model group. In therapeutic group 2, all indexes recovered after 5 d of CCl4 administration.

CONCLUSIONSGarlic oil can prevent acute liver injury induced by CCl4 and the effect is better in ahead of 2 h group than others.

Objective To evaluate the value of positron emission tomography(PET)-CT imaging combined with continual detection of CA_(125)in serum for diagnosis of early recurrent ovarian epithelial carcinoma.Methods Twenty six patients received PET-CT imaging,who were all diagnosed as primary epithelial ovarian cancer of stage Ⅱ-Ⅳ and had complete remission after cytoreductive surgery and multiple courses of chemotherapy in Shandong Provincial Cancer Hospital.After a steady period,all patients experienced progressive rising of CA_(125)values 3 times in 2 months.But no positive lesion was found by CT, or although suspicious positive focus was found,the recurrent and(or)metastatic extent was not definite. Out of 26 patients,16 were delivered rechemotherapy and(or)radiotherapy,and 10 received re- cytoreductive surgery.Results(1)Of 26 patients,the value of CA_(125)was more than 35 kU/L in 17,and in 14 of 17,pelvic or abdominal cavity recurrence was diagnosed by CT and PET-CT,and 4 showed simuhaneously distant metastasis on PET-CT.In the remaining 3 patients of which CT findings were negative,2 had pelvic and abdominal cavity recurrence,and one had bone metastasis on PET-CT.Of 9 patients with progressive rising CA_(125)levels but the value was less than cut-off(

OBJECTIVETo investigate whether the alterations of microtubule and microfilament expression are responsible for the neurotoxicity of carbon disulfide.

METHODSWistar rats were administered with carbon disulfide by gavage at a dosage of 300 or 500 mg/kg for continuous 12 weeks (five times per week). Spinal cords of carbon disulfide-intoxicated rats and their age-matched controls were Triton-extracted and ultracentrifuged to yield a pellet and a corresponding supernatant fraction. Then, the contents of alpha-tubulin, beta-tubulin, and beta-actin in both fractions were determined by immunoblotting. In the meantime, their mRNA levels in spinal cords were quantified using reverse transcriptase-polymerase chain reaction (RT-PCR).

RESULTSIn the supernatant fraction, the contents of beta-tubulin and beta-actin in both treated groups increased significantly (P < 0.01) the content of beta-tubulin increased by 141% and 158% respectively, and the content of beta-actin increased by 19% and 32% respectively. In the pellet fraction, the content of beta-tubulin in both groups increased by 107%(P < 0.01) and 118%(P < 0.01) respectively, and the others keep unaffected. In the meantime, the levels of of mRNA expression of beta-tubulin and beta-actin gene were elevated consistently in CS(2)-treated groups (P < 0.01) the levels of mRNA expression of beta-tubulin increased by 207% and 212% respectively, and the levels of mRNA expression of beta-actin increased by 94% and 91% respectively.

CONCLUSIONCarbon disulfide intoxication results in alternations of microtubule and microfilament expression, and the alternations might be related to its neurotoxicity.

Objective To understand the dietary nutrients among rural stranded children.Methods 2551 children aged 2 to 7, including 1278 stranded children in the rural areas and another 1273 children served as controls were selected, using multistage stratified cluster random sampling. Dietary survey was performed with three-day weighing dietary method and questionnaire on food intake. Data on diet were analyzed and evaluated by the Dietary Reference Intakes (DRIs) recommend by Chinese Nutrition Society, to evaluate the levels on energy and nutrient intake among stranded children in the rural areas. Results The dietary pattern among rural stranded children mainly consisted of grains and vegetables, but the intakes of animal products, fruits, and snacks were significantly less than in the control group. The intakes of three major energy-producing nutrients were below the recommend nutrient intake. Minerals as calcium, zinc, selenium, kalium and vitamins as vitamin A, B1, B2were insufficient.Most of the rural stranded children took nutrients insufficiently, with 50% lack of adequate energy and 80% of protein, 90% of minerals (calcium, zinc etc.) and vitamins (vitamin B1 and vitamin B2 etc.).Sources from high quality protein was insufficient, only consisting 35% of the total protein, but overabundant (over 64 % ) from the plants. The intake of plant-sourced iron was overabundant, accounted for 87%. Conclusion The dietary pattern was unsatisfactory with insufficient intake of energy-sourced proteins and some nutrients. The sources of energy, protein, and iron were mostly obtained from underbalaneed foods. It is necessary to improve the dietary nutrients status among rural stranded children aged 2-7 years.

OBJECTIVETo observe the effect of glycoprotein receptor blockade tirofiban in acute anterior myocardial infarction patients without ST segment resolution after primary percutaneous coronary intervention (PCI).

METHODSFrom April 2006 to April 2008, 157 acute anterior myocardial infarction patients without ST segment resolution after PCI were randomly allocated to tirofiban (intravenous bolus 10 microg/kg followed by intravenous infusion of 0.15 microgxkg(-1)xmin(-1) for 48 h, n = 80) or equal volume saline (control group, n = 77). Baseline characteristics, PCI features and clinical outcomes during hospitalization, left ventricular ejection fractions (LVEF) and major adverse cardiac events (MACE, including death, re-infarction and target vessel revascularization) at 30 and 180 days after discharge were compared between the two groups.

RESULTSThe baseline clinical characteristics were comparable between the two groups. Compared to control group, the MACE rates and re-infarction rates at 30 days (6.3% vs.18.2%, P < 0.05; 1.3% vs.9.1%, P < 0.05, respectively) and 180 days (10.0% vs.23.4%, P < 0.05; 2.5% vs.10.4%, P < 0.05, respectively) were significantly reduced in tirofiban group. LVEF value was significantly higher in tirofiban group at 30 days and 180 days compared with those in control group [(51 +/- 6)% vs. (46 +/- 8)%, P < 0.05; (57 +/- 7)% vs. (50 +/- 9)%, P < 0.05]. Hemorrhagic complications were similar between the two groups.

CONCLUSIONUse of tirofiban for acute anterior myocardial infarction patients without ST segment resolution after PCI is safe and can significantly improve 30 and 180 days clinical outcomes after discharge.

OBJECTIVETo investigate the value of intensity modulated radiation therapy (IMRT) for patient with gynecological malignancies after treatment of hysterectomy and chemotherapy/radiotherapy.

METHODSAll 32 patients with cervical or endometrial cancer after hysterectomy received full course IMRT after 1 to 3 cycles of chemotherapy (Karnofsky performance status(KPS) > or =70). Seventeen of these patients underwent postoperative preventive irradiation and the other 15 patients were pelvic wall recurrence and/or retroperitoneal lymph node metastasis, though postoperative radiotherapy and/or chemotherapy had been given after operation.

RESULTSThe median dose delivered to the PTV was 56.8 Gy for preventive irradiation, and 60.6 Gy for pelvic wall recurrence or retroperioneal lymph node metastasis irradiation. It was required that 90% of iso-dose curve could covere more than 99% of GTV. However, The mean dose irradiated to small intestine, bladder, rectum, kidney and spinal cord was 21.3 Gy, 37.8 Gy, 35.3 Gy, 8.5 Gy, 22.1 Gy, respectively. Fourteen patients presented grade I (11 patients) or II (3 patients) digestive tract side-effects, Five patients developed grade I or II bone marrow depression. Twelve patients had grade I skin reaction. The overall 1-year survival rate was 100%. The 2- and 3- year survival rate for preventive irradiation were both 100%, but which was 5/7 and 3/6 for the patients with pelvic wall recurrence or retroperioneal lymph node metastasis.

CONCLUSIONIntensity modulated radiation therapy can provide a better dose distribution than traditional radiotherapy for both prevention and pelvic wall recurrence or retroperioneal lymph node metastasis. The toxicity is tolerable. The adjacent organs at risk can well be protected.

OBJECTIVETo probe into the mechanism and methods of needle knife relaxing therapy for treatment of osteoarthritis of knee from biomechanical view.

METHODSNeedle knife relaxing therapy was given to 92 pain points around the knee joint in 14 cases of osteoarthritis of knee, and the displacement of the local pain point under the stress of 500 g (L500 g) was measured and the VAS scores were recorded before and after treatment.

RESULTSL500 g of the pain point was (4.72+/-1.03) mm before treatment and (5.39+/-1.01) mm after treatment with a very significant difference before and after treatment (P<0.01), and VAS score was (7.10+/-1.49) points before treatment and (1.49+/-1.24) points after treatment with a very significant difference before and after treatment (P<0.01), and there was a linear correlation between the changes of L500 g and VAS scores.

CONCLUSIONThere was close connection between the local pain and tension of local soft tissue in knee osteoarthritis. The needle knife relaxing therapy can relieve the neurovascular compression or traction syndrome by relaxing the local contracted, adhesive soft tissue, so as to relieve tension pain and finally recover internal force equilibrium of the knee joint.
