Objective:To investigate the clinical characteristics of patients infected with Brucella Melitensis ( B. Melitensis) type 1 and type 3 in Hulunbuir, Inner Mongolia Autonomous Region. Methods:A retrospective analysis method was used to collect clinical medical records of patients with brucellosis admitted to Hulunbuir People's Hospital from June 2013 to August 2017, and 71 patients with brucellosis positive in blood culture and identified by polymerase chain reaction (PCR) and AMOS-PCR were selected as the study subjects. According to the identification results, they were divided into B. Melitensis type 1 and type 3 groups. General information, epidemiological characteristics, clinical characteristics, laboratory examinations, complications and efficacy of the two groups were compared. Results:Among 71 patients with brucellosis, 22 cases were B. Melitensis type 1, including 16 males and 6 females, aged (39.91 ± 16.04) years old; 49 cases were B. Melitensis type 3, including 34 males and 15 females, aged (40.67 ± 18.72) years old. There were no significant differences in gender composition and age between the two groups (χ 2 = 0.081, t = 0.166, P > 0.05). There were 10 cases(45.5%) of B. Melitensis type 1 patients living in agricultural areas, 10 cases (45.5%) in pastoral areas, and 2 cases (9.1%) in cities; there were 40 cases (81.6%) of B. Melitensis type 3 patients living in agricultural areas, 7 cases (14.3%) in pastoral areas and 2 cases (4.1%) in cities, and the difference between regions was statistically significant (χ 2 = 9.276, P < 0.05). Testicular swelling and pain symptoms [22.7% (5/22), 6.1% (3/49)] in B. Melitensis type 1 and type 3 patients were compared, the difference was statistically significant (χ 2 = 4.187, P < 0.05); other clinical features were compared, the differences were not statistically significant ( P > 0.05). There were no significant differences in white blood cell count (WBC) and platelet count (PLT) decreased, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) increased between the two groups ( P > 0.05). The number of complications in B. Melitensis type 1 and type 3 patients were 12 cases (54.5%) and 14 cases (28.6%), respectively, and the difference between the two groups was statistically significant (χ 2 = 4.413, P < 0.05). Ten cases (45.5%) of B. Melitensis type 1 patients were cured, 12 cases (54.5%) were improved, 34 cases (69.4%) of B. Melitensis type 3 patients were cured, 15 cases (30.6%) were improved, and there were no invalid or relapsed patients in both groups, the difference in curative effect between the two groups was statistically significant (χ 2 = 3.690, P < 0.05). Conclusions:In Hulunbuir, Inner Mongolia Autonomous Region, there are differences in the living areas of B. Melitensis type 1 and type 3 patients. The B. Melitensis type 1 patients are prone to testicular swelling and pain and brucellosis complications.

OBJECTIVETo investigate clinical effects of three-column reconstruction via single posterior approach for the treatment of unstable thoracolumbar fractures accompanied by posterior column injury.

METHODSFrom December 2008 to May 2010,three-column reconstruction via posterior approach was implemented to 21 patients with unstable thoracolumbar fractures accompanied by posterior column injuries. There were 13 males and 8 females, ranging in age from 23 to 54 years old(averaged,35.5 years old). Injured vertebrae: 1 patient had injury in T11, 4 patients had injuries in T12, 8 patients had injuries in L1, 5 patients had injuries in L2, 3 patients had injuries in L3. The Cobb angle was (25.34 +/- 3.42) degrees. The operation time,blood loss during operation, Cobb angle and the bony fusion were observed.

RESULTSTwenty-one patients were followed up, and the duration ranged from 24 to 27 years old, with an average of 25.6 months. The operation time ranged from 135 to 275 min, with a mean of 185 min. The blood loss during operation ranged from 700 to 1 650 ml (averaged, 870 ml). All the patients had complete decompression. Postoperative Cobb angle was (4.01 +/- 2.03) degrees, and (4.34 +/- 2.38) degrees at the latest follow-up. All the patients got bony fusion.

CONCLUSIONTo the patients with unstable thoracolumbar fractures accompanied by posterior column injuries, three-column reconstruction via single posterior approach has both anterior approach and posterior approach advantages, which can obtain excellent clinical outcomes.

OBJECTIVETo observe the effect of tetrandine on gene expression of collagen type I, collagen type III, transformation growth factor-beta1 and to investigate the inhibitory effect of tetrandine on the scar tissue hyperplasia in rabbits' ears.

METHODSAfter the scar model was formed on the rabbits' ears, the rabbits were divided into 4 groups to receive intro-lesion injection with saline, or prednisolone (Pre) or tetrandrine in low concentration (L-Tet, 1.0 mg/ml) or tetrandrine in high concentration (H-Tet, 7.5 mg/ml). The morphological changes of scar tissue were observed. The changes of fibroblasts quantity and collagen expression were observed with HE and Masson staining. Immunohistochemical study was used to observe the expression level of collagen type I and collagen type III and TGF-beta1. Collagen type I and collagen type III and TGF-beta1, and signal factor Smad 3 mRNA were detected with RT-PCR.

RESULTS(1) 24 days after injury, all the wounds healed completely with formation of red, tough and hypertrophic scar. HE and Masson staining showed significant increase of fibroblasts and collagen density with irregularly arrangement. (2) Compared with that in saline group, the scar in other groups became softer, lighter and thinner, especially in H-Tet group. (3) HE and Masson staining shows the scar in Tet and Pre groups contained less fibroblasts and lower collagen dentsity with comparatively regular arrangement than that in saline group (P < 0.01), especially in H-Tet group. (4) According to the immunohistochemical study, the expression of collage type I and III and TGF-beta was positive in all the groups, but the positive rate and the ratio of collagen density I to III decreased in the order of saline, L-Tet, H-Tet and Pre groups (P < 0.01). (5) PT-PCR detection results showed that the amplification bands brightness of collagen type I and III and TGF-beta1 and signal molecular Smad 3 mRNA in scar tissue were obviously different. Compared with that in saline group, the expression of collagen type I and III and TGF-beta1 and Smad 3 mRNA decreased in Tet and Pre groups (P < 0.01). H-Tet group showed the most obvious reduce in the expression of type I collagen and TGF-beta1 and Smad 3 mRNA. Conclusions Tetrandine can significantly suppress the expression of collagen type I and collagen type III and TGF-beta1 on hypertrophic scar of rabbit ears, and reduce signal factor Smad 3 mRNA' s expression. It may be one of the important mechanism for its inhibitory effect on scar hyperplasia.

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 study the changes of anorectal motility and rectal sensation in the elderly patients with ulcerative colitis (UC). Methods The anorectal motility and rectal sensation were investigated by Medtronic PC-Polygraf HR made by Sweden in 35 non-elderly patients versus 19 elderly patients with UC, and 20 non-elderly healthy subjects (HS) and 28 elderly HS were as control group. Results (1) The static pressure, pressure of anal sphincter and the maximal squeeze pressure of anal sphincter in non-elderly patients and elderly patients with UC showed no significant differences compared with those in non-elderly HS and elderly HS group (elderly patients with uc vs. ederly HA:t= 1.311,1.298,1.401;nonederly patients with uc vs. nonederly HS: t=1.294,1.299,1.322all P＞0.05). When abdominal pressure was increased, the net increased pressure of anal sphincter was (2.8±1.1) kPa in the elderly patients with UC, (2.9±1.3) kPa in the non-elderly patients with UC. The pressures were lower in two UC groups than in HS groups [elderly HS group:(3.8±1.2) kPa; non-elderly HS group:(3.9±1.2) kPa,elderly patients with uc vs. ederly HS:t=2.238,nonelderly patients with us vs. nonederly HS:t=2.243 all P＜0.05]. (2)The rectal lowest volume of sensory threshold, the maximal volume of tolerance and the maximal compliance were (85±30) ml, (180±69) ml, (26. 5±8.8) ml/kpa in elderly patients with UC and (65±15) ml, (170±58) ml, (22.6± 10. 3) ml/kPa in non-elderly patients with UC. They were lower than in each HS group [elderly HS group (95±31) ml, (205±78) ml, (32.9±12.9) ml/kPa; non-elderly HS group:(78±38) ml, (190±50) ml, (30.8± 15.2) ml/kpa, all P＜0. 01]. (3)The rectal lowest volume of sensory threshold, the maximal volume of tolerance and the maximal compliance in elderly patients with UC were higher than in non-elderly patients with UC (elderly patients with uc vs. elderly HS:t=3. 121,3. 135,3.146,nonederly patients with uc vs. non elderly HS: t= 3.162, 3.141, 3.188 elderly patients with uc vs. nonelderly patients with uc: t = 2. 246,2. 239,2. 240 all P＜ 0. 05). The rectal lowest volume of sensory threshold, the maximal volume of tolerance in elderly HS group were higher than in non-elderly HS group (ederly HS vs. t = 2. 328,2. 301 all P＜0. 05). Conclusions There are some anorectal motility disturbances in UC. Higher sensitivity, lower tolerance, lower compliance of rectum and weakened anal automatic control function in UC may be associated with diarrhea and frequent defecation. The rectal sensation threshold to volume stimulus is higher in elderly HS than in non-elderly HS group. The sensibility to volume ectasis of rectum is weakened and the survivability of rectum is increased in elderly patients with UC.

OBJECTIVETo investigate the clinical outcomes of semicircular decompression in treating old thoracolumbar fractures and intractable neuropathic pain.

METHODSFrom September 2009 to September 2013, 21 patients with old thoracolumbar fracture and intractable neuropathic pain were treated with semicircular decompression. Among initial surgery, posterior pedicle screw fixation was used in these patients, with or without laminectomy. All patients were male, range in age from 20 to 28 years old with an average of (25.00±2.38) years. Vertebral body residual bone block resulted in intra-spinal placeholder more than 50%. All patients were complete spinal cord injury (ASIA grade) or cauda equina injury. VAS scores was from 6 to 10 points with the mean of 7.14±0.91. In these patients, MRI, CT, X-rays were performed; denomination and dosage of analgesics were recorded; nerve function and pain status were respectively evaluated by ASIA grade and VAS score before and after operation.

RESULTSAll patients were followed up from 8 to 32 months with an average of (17.29±6.02) months. All bone fragments of spinal canal were removed and spinal cord decompressions were achieved. At final follow-up, VAS scores were from 0 to 8 points with an average of (2.43±2.46) points, and were obviously reduced than peroperative data (P<0.05). Eleven cases of them stopped analgesic intake and 7 cases reduced using. Three patients' symptoms and VAS scores were not improved.

CONCLUSIONOld thoracolumbar fractures and intractable neuropathic pain need receive imaging examination as soon as possible and consider semicircular decompression therapy if bone fragments were in vertebral canal and spinal canal stenosis existed. This therapy can effectively relieve pain and profit nerve functional recovery.

OBJECTIVETo access the sustained immune effect in influenza A H1N1 vaccine vaccinated-blood donors as well as the level of anti-H1N1 IgG in unvaccinated-blood donors in order to provide reference for preventing and treating influenza A H1N1.

METHODSAnti-H1N1 IgG was detected in 1166 vaccinated-blood donors as well as 1265 unvaccinated-blood donors by ELISA method in Dongguan from January 2010 to June 2010.

RESULTSThe mean positive rate and high-titer rate of anti-H1N1 IgG were 78.82% and 46.57% respectively, both of which were sustained at relatively high level after reaching their peak at vaccination time of 71-90 d. The mean positive rate of anti-H1N1 IgG in unvaccinated-blood donors was 26.01%. No difference was found in the positive rate of anti-H1N1 IgG among different gender or age groups (P > 0.05).

CONCLUSIONThe influenza A H1N1 vaccine, with good sustained immune effect, plays an important role in preventing and treating influenza A H1N1. The positive rate of anti-H1N1 IgG in influenza A HIN1 vaccine unvaccinated-blood donors is low. Vaccination should be strengthened.
