AIM: To observe if there is a synergistical effect on induction of apoptosis when arsenic trioxide alone or combination with bortezomib in KM3 cells. METHODS: KM3 cells were treated with arsenic trioxide alone or combined with bortezomib, the numbers of viable cells were determined by trypan blue exclusion. Cell growth inhibition was examined by MTT method. The cells were simultaneously stained with annexin V-FITC and PI and apoptosis was determined by bivariate flow cytometry using a FACScan. Reverse trascriptional-PCR (RT-PCR) method was used to examine the change of p65 mRNA and Western blotting to measure the expression of protein p65, p-p65, caspase-3, -8, -9, and poly ADP-ribose polymerase (PARP). RESULTS: Arsenic trioxide inhibited the cell growth and induced apoptosis. The mechanism was responsible for the activation of caspase-mediated induction of apoptosis. A synergistic effect of combination with bortezomib on apoptosis was observed. CONCLUSION: Arsenic trioxide inhibits KM3 cell growth and induces apoptosis with a synergistical effect when cotreated with bortezomib.

ObjectiveTo find out the risk factors and the incidence of lithiasis. MethodsA questionnaire was formulated by the National Biliary Surgical Group. It was sent to the medical staff of all levels of hospitals in the Zunyi Region, Guizhou to fill in on surgically proven cases of cholelithiasis. The clinical data were collected and analyzed using SPSS 13.0. ResultFor lithiasis, the gender ratio was 1∶ 1.78; the peak age was 41-year and 51-year respectively. The proportion of cholecystolithiasis (n =4456 ; 86.76 ％) and choledocholithiasis (n =554;10.79 ％ ) was comparatively higher than in other regions in China. ConclusionsThe commonest type of lithiasis in Zunyi was cholecystolithiasis. There was an increasing tendency for lithiasis to develop in young people. Lithiasis was closely associated with factors such as gender, food and occupation.

Objective:To purify and characterize the major antigenic components of sand swimming crab,and provide theoretical evidences for the research of standardization of allergenic vaccine.Methods:The crude extract of Linnaeus was prepared using classical method, and electrophoresis of SDS-PAGE was used to separate the proteins of each group. The allergen proteins of 26 crab were identified using Western blot. To distinguish between the primary allergen proteins and secondary allergen proteins, FPLC(Gel Chromatography and ion exchange chromatography) was used to filtrate and identify the allergen protein.Results:SDS-PAGE analysis revealed that sand swimming crab proteins were composed of at lease 9 discrete protein bands, which molecular weight ranging from 13 000 to 90 000. Major bands were of 20 900, 24 200, 27 100, 29 200, 33 700, 38 900, 48 700, 74 700, 89 100 respectively. Western blot assay indicated that the crude extract reacted with sera obtained from 26 crab allergenic subjects and contained 5 allergen bands altogether, and the bands of 74 400 and 48 700 were the major allergenic components. The positive rates of the two major allergen proteins were both 100%, indicating the allergenic components maintained the immunocompetence after yielding from chromatography.Conclusion:The 74 400 and 48 700 bands are the major allergens of sand swimming crab. The major allergen proteins can be purified by chromatography.

Objective To evaluate the clinical application of May-Grunwald-Giemsa staining followed by fluorescence in situ hybridization (MGG-FISH) technique in the differentiation diagnosis of Ph-chromosome positive acute lymphoid leukemia (Ph + ALL) from chronic myeloid leukemia in lymphoid blast crisis(CML-LBC). Methods The bone marrow smears of 4 patients with Ph+ ALL, 4 patients with CML-LBC, 1 patient with CML in myelocytic blast crisis complicated with lymphoma and 1 patient with CML in mixed blast crisis were assayed with the MGG-FISH technique in which the spectrum green labeled BCR and spectrum orange labeled ABL dual color dual fusion probes were used. Based on the morphological classification, the percentages of BCR-ABL positive cells were subsequently determined respectively in the erythroid, myeloid and lymphoid hneages for the 10 specimens. Results According to the MGG-FISH analysis, the erythroid lineage was not involved in the 4 Ph+ ALL specimens without BCR/ABL positive cells. While the BCR/ABL positive percentage of myeloid cells was 11% (1/9), 8% (1/12), 0% (0/8) and 10% (1/10) respectively and that of lymphoid cells was 97% (76/78), 98% (87/89), 98% (97/99) and 97% (75/77) respectively. On the other hand, the BCR/ABL positive percentage was 100% (8/8), 91% (10/11), 82% (9/11), 88% (7/8) in the erythroid lineage, 89% (8/9), 96% (94/98), 100% (47/47), 98% (40/41)in the myeloid lineage and 96% (78/81), 93% (52/56), 96% (68/71), 95% (58/61) in the lymphoid lineage respectively for the 4 CML-LBC specimens. The BCR/ABL positive percentages of the other 2 specimens were all above 80% and through MGG-FISH analysis we also identified the source of the malignant clones and ascertained the diagnosis of the 2 patients. Conclusions The MGG-FISH technique has proved useful in providing rapid and precise differentiation between Ph + ALL and CML-LBC. The source of the malignant clones can also be analyzed by this technique.

Objective:To observe the effect of xylitol on the cyclooxygenase(COX)-2 expression of renal tubule in diabetic rats.Methods:The Wistar rats were randomly divided into normal control group(group NC),diabetes control group(group DC),5% xylitol-treated group(group 5%),10% xylitol-treated group(group 10%)and 20% xylitol-treated group(group 20%).At the end of 8 weeks,the expression of COX-2 in kidney tissue,the level of serum uric acid,allantoin and creatinine were tested in rat groups.Results:The levels of serum uric acid and allantoin were higher in group 5% and group 10% compared with that of group DC.The differences in levels of serum uric acid and allantoin were statistical significance between group 10% and group DC(P ＜ 0.05),whereas,the lower levels of serum uric acid and allantoin were found in group 20% compared with those of group DC(P ＞ 0.05).The levels of urine uric acid and allantoin were lower in group 5% and group 10% than those of group DC(urine uric acid,P＞ 0.05 and allantoin,P＜ 0.05),whereas,group 20% had higher levels of urine uric acid and allantoin than those of group DC(P＜ 0.05).The fractional excretion of uric acid(FEUA)was lower in group 5% and group 10% compared with that of group DC(P ＜ 0.05).The FEUA was higher in group 20% than that of group DC(P ＜ 0.05).The expression of COX-2 was significantly increased in group 5% and group 10% compared with that of group DC(P ＜ 0.05),but the expression of COX-2 decreased in group 20%(P ＜ 0.05).Conclusion:The lower and mediate doses of dietary xylitol could aggravate the tubular injury through increasing the level of serum uric acid and the expression of COX-2 in renal tubule.The higher doses of xylitol could increase the excretion of uric acid and down-regulate the expression of COX-2 in renal tubule.

BACKGROUND:Percutaneous vertebroplasty and percutaneous kyphoplasty in the treatment of osteoporotic vertebral compression fracture have obtained good outcomes, because the traditional method is invalid, but there are a variety of choices in operation time, anesthesia, surgical approach and method, and each method has its advantages and disadvantages. OBJECTIVE:To investigate the effect and preponderance of the manual reduction combined with unilateral percutaneous vertebroplasty under general anesthesia in the treatment of osteoporotic vertebral compression fractures. METHODS:A total of 53 patients with single vertebral osteoporotic vertebral compression fractures, who were treated with percutaneous vertebroplasty, were retrospectively analyzed from July 2012 to December 2014. The new method group (32 cases) received manual reduction, underwent unilateral pedicle puncture and bone cement injection during unilateral percutaneous vertebroplasty under general anesthesia. The conventional method group (21 cases) received conventional percutaneous vertebroplasty. RESULTS AND CONCLUSION: There was an average of 6-month folow-up (3-14 months). Significant differences in visual analogue scale scores, vertebral compression ratio and kyphosis Cobb’s angle were detected in the new method and the conventional method groups at 3 days post surgery and during final folow-up compared with before surgery (P < 0.01). No significant difference in visual analogue scale scores was found between the two groups (P > 0.05). Compared with the conventional method group, postoperative vertebral compression ratio, kyphosis Cobb’s angle and bone cement leakage rate were significantly lower in the new method group (P < 0.01). Results verified that the new method combined with the advantages of percutaneous vertebroplasty and percutaneous kyphoplasty, the advantages of unilateral and bilateral puncture approach. The new method can correct kyphosis deformity, effectively recover the vertebral height and physiological curvature and the puncture is safe. Simultaneously, the leakage rate of bone cement is reduced, and the distribution of bone cement is ideal.

ObjectiveTo study the effects of 6-hydroxydopamine (6-OHDA),and inhibitors for vesicular monoamine transporter (VMAT) on 5-hydroxytryptamine (5-HT),norepinephrine (NE) and dopamine (DA) and the expressions of tryptophan hydroxylase (TpH) mRNA,dopamine-beta-hydroxylase (DβH) mRNA and tyrosine hydroxylase (TH) mRNA in PC12 cells.Methods The cell viability was determined using MTT assay, the density of 5-HT, NE and DA was detected using enzyme-linked immunosorbent assay,and the expressions of TpHmRNA,DβHmRNA and THmRNA were detected using RT-PCR in PC12 cells at different time points (0,12,24,36,48 h )after exposure to different concentrations of 6-OHDA(25,50,100,200 μmol/L),and VMAT inhibitors,reserpine (50,100,400,1600 nmol/L),which combined with 6-OHDA( 100 μmol/L).Results (1)The cell viability declined with the increasing concentration of 6-OHDA which showed time dependence.The cell viability in PC12 cell which treated with reserpine decreased significantly in the responding group.The density of 5-HT in PC12 cell did not decrease with the increasing concentration of 6-OHDA,but the change had the time dependence,and the density of 5-HT was lowest at 36 h.The density of NE decreased with the increasing concentration of 6-OHDA which showed time dependence. The density of DA in PC12 cell decreased with the increasing concentration of 6-OHDA,but the change did not have the time dependence.The density of 5-HT,NE and DA in PC12 cell which treated with reserpine decreased significantly in the responding group. (2) The expressions of TpHmRNA, DβHmRNA and THmRNA in PC12 cell decreased with the increasing concentration of 6-OHDA which showed time dependence.The expressions of TpHmRNA(0.006 ± 0.001,0.003 ± 0.000,0.003 ± 0.000,0.002 ± 0.000) ; DβHmRNA (0.005 ± 0.002,0.003 ± 0.001,0.002 ±0.001,0.001 ± 0.000) and THm RNA (0.005 ± 0.002,0.003 ± 0.001,0.002 ± 0.001,0.001 ± 0.000) in PC12 cell which treated with reserpine decreased significantly in the responding group(F =13.336,9.000,9.393,all P =0.000).Conclusions6-OHDA can decrease the cell viability in PC12 cell,reduce the density of 5-HT,NE and DA and decrease the expressions of TpHmRNA,DβHmRNA and THmRNA,and the effects have dose and time dependence.Reserpine can aggravate this damage.

Objective To investigate the traumatic characters, the causative factors and the outcomes of surgical treatments of cervical spinal cord injuries without radiographic abnormality(SCIWORA).Methods From March 2000 to July 2004, 81 patients of cervical SCIWORA undergone surgery were evaluated retrospectively. There were 55 males and 26 females, with a mean age of 57.3 years. According to the mechanisms of injuries and pathological changes of the cervical spine, the causative factors were divided into 3 groups: hyper-flexion type of injury (1 or 2 segments) with protrusion or prolapse of the cervical intervertebral discs (19 cases), hyper-extension type injury with multiple (≥3 segments) cervical spinal stenosis (41cases), and whiplash injury with multiple cervical spinal stenosis and segmental intervertebral instability or anterior protrusion of the cervical intervertebral discs (21 cases). A variety of surgeries as anterior discectomy with interbody fusion, multiple posterior decompressions with cervical laminoplasty, and multiple posterior decompressions with internal fixation at the facet joints were performed based the classification. Results The average follow-up period was 78.5 month (54-118 months). During the follow-up of 1 month, 3 months,1 year and last visit post-operatively, the rate of JOA improvement were 25.1%, 41.3%, 63.6% and 60.9%respectively. In the long-term follow-up, the good ratio of neurological function was obtained with 80.2%.Conclusion SCIWORA is considered as a course of acute, dynamic and limited injury. In spite of common clinical manifestation, its traumatic characters and causative factors are different indeed. The distinct improvement of neurological function can also be achieved with proper classification and surgery.
