Objective To study the tolerance to 188Re-1-hydroxy-1 ,1-ethylidene disodium phosphonate(HEDP) in patients with bone pain caused by osseous metastases. Methods Thirty-one patients(10with prostate cancer, 9 with breast cancer, 3 with lung cancer, 5 with liver cancer, 2 with rectal cancer, 1with esophageal cancer and 1 with renal cancer) received a single injection dose of 188Re-HEDP. The patients were divided into four groups according to the injection dose: 20 MBq/kg (6 patients), 30 MBq/kg(6 patients), 40 MBq/kg (9 patients), and 50 MBq/kg (10 patients). Haematological toxicity (WHO grading) of grade Ⅲ- Ⅳ was considered unacceptable. Vital signs and adverse effects after injection were recorded for 8 weeks. Blood counts were measured weekly during a period of 8 weeks. Biochemical parameters and electrocardiogram were assayed at week 4 and 8. Statistical analysis was performed for per-protocol (pp) population (t-test). Results Twenty-seven patients belonged to PP population with 5 in the group of 20 MBq/kg, 5 in the group of 30 MBq/kg, 8 in the group of 40 MBq/kg and 9 in the group of 50 MBq/kg.No obvious adverse effects and no significant change of vital signs, electrocardiogram, liver and renal function were found after injection. Alkaline phosphatase was slightly higher than baseline at week 4 and 8 after therapy, but the difference was not statistically significant. In the 20 MBq/kg group, reversible grade Ⅰ leucopenia was noted in 1 patient. In the 30 MBq/kg group, 2 patients showed reversible grade Ⅰ leucopenia including 1 alone with reversible grade Ⅲ thrombopenia. In the 40 MBq/kg group, reversible grade Ⅰ leucopenia and thrombopenia was observed in 1 patient and reversible grade Ⅱ leucopenia and thrombopenia in another patient. In the .50 MBq/kg group, 3 patients showed reversible grade Ⅱ leucopenia. The lowest level of thrombopenia was at week 4(143.5 × 109/L), leucopenia at week 6 (5.4 × 109/L) and anaemia at week 8(t = 3.1325, 3.3156, 3.4917, all P ＜ 0. 05 compared with baseline). At week 8, the mean level of platelet and leucocyte recovered to baseline. "Bounce pain" was found in 2 of 27 patients (7.41%).Conclusions The dose of 20 MBq/kg, 30 MBq/kg, 40 MBq/kg or 50 MBq/kg of 188Re-HEDP do not cause significant side effects on cancer patients with bone metastases, though there is a tendency that the haematological toxicity may increase as the dose of 188Re-HEDP increases.

Objective To evaluate the causes of local masses found after periocular fat grafting,and the way of treatment in order to avoid the medical dispute.Methods In 37 patients with local mass being repaired,15 patients with superficial bulges were treated through surgical removal and as piration;10 patients with focal masses were treated with aspiration;12 patients with bulges close to eyelid margin and failure after the first two treatment methods were treated through incision.Results Histopathologic findings showed the characteristic features of lipogranuloma.Chronic inflammatory cells were infiltrated.Numerous,variable-sized lipid vacuoles were surrounded by histiocytes and for eign body-type giant cells.There were areas of fibrosis and fat necrosis.35 cases were followed-up for 3 months to 1 years.Both doctors and patients were satisfied with results in 27 cases,basically satisfied in 6 cases,but not satisfied in 2 cases.Two patients were lost to follow up.Conclusions The special complication of masses in the periocular fat grafting operation can be greatly improved with the personalized therapy.

OBJECTIVETo explore clinical effects of Ilizarov technique at stage I for repairing tibial post-traumatic osteomyelitis with bone and skin defect.

METHODSFrom June 2010 to December 2013,44 patients with tibial post-traumatic osteomyelitis with bone and skin defect were treated with Ilizarov technique at stage I . Among them, there were 35 males and 9 females aged from 18 to 70 years old with an average of 42.5 years old. Bone defect ranged from 4 to 16 cm, skin defect ranged from 3 cm x 4 cm to 5 cm x 16 cm. The operation was performed debridement thoroughly, removed inflammatory bone section, osteotomy invasively, install circular external fixator by Ilizarow technique; screw nut were rotated at 1 week after operation, and prolonged 0.5 to 1.0 mm everyday. Wound surface, new born callus and bone healing were observed to evaluate clinical effects.

RESULTSAll patients were followed up from 11 to 36 months with an average of 18.5 months. Bone defect after osteotomy was from 6 to 22 cm with an average of 11.5 cm; the time of wound healing time ranged from 21 to 79 d with an average of 38 d; bone defect healing time was from 8 to 15 months with an average of 12.5 months. All patients were cured, no recurrent infection, refracture and shorten of calf deformity were occurred.

CONCLUSIONRepairing tibial post-traumatic osteomyelitis with bone and skin defect by llizarov technique at stage I has advantages of less trauma, low inflammatory recurrence rate, could avoid multiple complex operation, and receive definite curative effect.

OBJECTIVETo screen the differential expression gene profile in nasal mucosa of seasonal allergic rhinitis (SAR) and SAR with asthma, oligonucleotide microarray (Affymetrix HG-U133-plus2) was employed to analyze the changes of gene expressions with GeneSpring software.

METHODSInferior turbinate mucosa was obtained from five SAR patients and four SAR with asthma patients. Total RNA was extracted from the nasal mucosal biopsies and pooled into one SAR control pool and one SAR with asthma patient pool, and biotin-labeled cRNA probes were hybridized with Affymetrix HG-U133-plus2 array. The hybridization results were confirmed by RT-PCR analysis. The analysis of differential expression profiles were performed by GeneSpring software 7.3.

RESULTSOut of 47,000 analysed transcripts, 1,900 genes were differentially expressed at least 2-fold in which 849 genes were up-regulated and 1,051 genes were down-regulated in nasal mucosa of SAR with asthma patients compared with that in SAR patients. These genes were involved in cell metabolism, gene transcription, cell proliferation, signal transduction, immune response, enzyme activity, transmembrane receptor activity, cytoskeletal protein binding, and many other aspects. Pathway analysis displayed 161 groups, of which including more than 20 genes were as follow: cytokine-cytokine receptor interaction, focal adhesion, cell adhesion molecules (CAMs), regulation of actin cytoskeleton, cell communication, gap junction, MAPK signaling pathway, calcium signaling pathway, leukocyte transendothelial migration, and purine metabolism.

CONCLUSIONSThe data suggested that multigentic expression and regulation changes were involved in the development of SAR and SAR complicated with asthma, whose molecular mechanisms might be elucidated by identification of these differential genes.

OBJECTIVETo explore the toxic effect of fluoride on the human thyroid cells (Nthy-ori 3-1) and its mechanism.

METHODSNthy-ori 3-1 cells were exposed to 0.0, 0.1, 1.0, 3.0 mmol/L of sodium fluoride (NaF) in vitro. After 24 hours incubation, 3 (4,5-Dimethylthiazol-z-yl)-3, 5-diphenyltetrazolium bromide (MTT) assay and lactate dehydrogenase (LDH) assay were used to measure cell viability and the LDH leakage rate. Reactive oxygen species (ROS) level, constituent ratio of the cell cycle, and apoptosis rate were measured by flow cytometry.

RESULTSComparing to viability of control group (set as 100.00%), the cell viability of the 1.0, 3.0 mmol/L fluoride-treated groups (76.64 +/- 9.13)%, (64.04 +/- 6.32)% were significantly decreased (all P values <0.01). LDH leakage rate and ROS level of the 3.0 mmol/L fluoride-treated group ((48.66 +/-7.15)%, (29993.50 +/- 1786. 86) FI) were significantly increased (all P values <0.01) compared to control group ((35.24 +/- 3.02)%, (13021.33 +/- 1067.55) FI). The G0/G1 phase cells of the 1.0 mmol/L fluoride-treated group ((40.76 +/- 5.65)%) were lower than control group (60.09 +/- 1.76)% (P < 0.01), yet the percentage of cells in S phase ((54.05 +/- 4.59)%) were higher than the control group (32.59 +/- 2.43) % (P < 0.01). Comparing to control group ((9.64 +/- 3.44)%), the percentage of apoptosis cells increased in the 3.0 mmol/L fluoride-treated group ((20.09 +/- 3.22)%) (P < 0.01).

CONCLUSIONTo Nthy-ori 3-1 cells, fluoride under experimental concentrations decreases cell viability, improve the LDH leakage rate, and ROS level. It blocks the cells in S phase and induce cell apoptosis.

OBJECTIVETo study the clinical and pathological features of primary lymphoma of the testis and try to find out the rational treatment modality.

METHODSRetrospective and follow-up analysis was conducted in 23 patients with primary lymphoma of the testis. Survival analysis was performed by Kaplan-Meier process.

RESULTSThe primary clinical symptom was painless tumefaction. 78.3% lesions were Stage I(E) on diagnosis. Most of them were intermediate grade B cell lymphoma. All patients received orchiectomy followed by chemotherapy and some followed by radiotherapy. The median survival time was 42 months. The overall survival rates at 1, 3 and 5 years were 100.0%, 59.8% and 36.5%, respectively. The disease-free survival rates at 1, 3 and 5 years were 66.7%, 42.3% and 36.3%, respectively.

CONCLUSIONPrimary lymphoma of the testis is preferably treated by multi-modality treatment. More than 6 cycles of chemotherapy is rational after orchiectomy. Regional radiotherapy tends to reduce the local relapse.

Objective To know the information about the past disease history and HBV infection in the male hit-the-pipe patients. Methods 452 male addicts that are accepting the treatment of abandoning drug habits in a drug-relief reformatory in Changsha City were randomly taken as the subjects, A questionnaire about the past disease history and daily life contact history was dispatched and collected. ELISA assay was used to detect the mark of the HBV infection and the liver function of the subjects. Results There was a statistical relationship between whether the persons in the studied sample have a past disease history of other viral hepatitis, and the HBV total infection, HbsAg infection, and large triple yang and little triple yang infections. Whether the addicts accepted blood products is statistically related to the HbsAg infection rate. Whether the addicts pricked holes on their ears for earrings is related to HbsAg infection, and little triple yang infection. Conclusions It is the most important influencing factors for HBV infection that the male addicts have a disease history of other viral hepatitis and other related medical history.

Objective:To observe the effects of moxibustion on the levels of glucose-6-phosphate dehydrogenase(G6PD)and reduced nicotinamide adenine dinucleotide phosphate(NADPH)in the plasma and spleen and the CD4+T-cell number in the spleen of rats with adjuvant arthritis,thus to explore the mechanism in rheumatoid arthritis(RA)treatment with moxibustion by regulating the CD4+T-cell proliferation through G6PD-mediated pentose phosphate pathway. Methods:Twenty-seven male Sprague-Dawley rats were randomly divided into a blank group,a model group,and a moxibustion group,with 9 rats in each group.Incomplete Freund's adjuvant was used to induce inflammation in the model group and the moxibustion group.The blank group and the model group were not intervened.In the moxibustion group,suspended moxibustion was performed at bilateral Zusanli(ST36),Guanyuan(CV4),and Ashi points for 30 min,once a day for 24 times in total.Hematoxylin-eosin staining was used to evaluate the histopathological changes of rat synovial tissue;the swelling degree of the rat toes was observed by measuring the toe volume;G6PD and NADPH in the spleen and plasma were detected by Western blotting and enzyme-linked immunosorbent assay.Flow cytometry was used to detect the CD4+T-cell number in the spleen. Results:Compared with the blank group,the levels of G6PD and NADPH in the plasma and spleen and the CD4+T-cell number in the spleen were significantly increased in the model group(P<0.01 or P<0.05).Compared with the model group,the NADPH level in the spleen and plasma and the CD4+T-cell number in the spleen in the moxibustion group decreased significantly(P<0.05 or P<0.01),and the G6PD level in the plasma decreased significantly(P<0.05),but there was no significant difference in the G6PD level in the spleen(P>0.05). Conclusion:Moxibustion can regulate immunity and improve joint synovial inflammation in RA.The mechanism may be that the G6PD-mediated pentose phosphate pathway reduces the production of metabolite NAPDH in CD4+T cells,thereby inhibiting the proliferation of naive CD4+T cells.
