Objective To observe the dynamic serological test results of 28 patients with acute brucellosis,and to investigate the relationship between serological test results and diagnosis,curative effect and prognosis of brucellosis.Methods Twenty eight patients(infected with sheep brucellosis) with acute brucellosis in the Department of Brucellosis in Heilongjiang Provincial Land Reclamation Headquarters General Hospital were selected as research subjects,and their serological changes were tested by means of tube agglutination test (SAT)and clinical outcomes were compared before and after each stage of treatment.In addition,symptoms of fever,weakness,sweating,joint pain,swollen lymph nodes and biochemical parameters [alanine aminotransferase (ALT),lactate dehydrogenase (LDH)] were also tested 3,6 and 9 weeks after the treatment.Results Antibody titer reached the peak at the third week,1 ∶ 400(++),which accounted for 39.29％ (11/28); 2857％(8/28) of the patients became negative at the sixth week; 50.00％ (14/28) became negative at the ninth week.Before the treatment,20(71.43％) patients had the symptom of fever,8 (28.57％) patients had the symptom of hyperhidrosis,28 (100.00％) patients had the symptom of joint pain,7(25.00％) patients had the symptom of lymph node enlargement,28 (100.00％) patients' ALT was elevated,and 26(92.86％) patients' LDH was elevated.After three weeks of treatment,except the three patients (10.71％) who occasionally had fever,the rest of the patient's temperature was returned to normal.Also the numbers of patients with the symptoms of fatigue,sweating and joint pain were significantly reduced,and specifically,the conesponding number was 13(46.43％),2(7.14％),and 21 (75.00％)patients,respectively.ALT and LDH returned to normal(only one patient's ALT was out of the range).At the sixth week,all the patients' symptoms of fever and hyperhidrosis disappeared.The number of patients with the symptoms of joint pain and lymph node enlargement reduced to 12(42.86％) and 3(10.71％),respectively.The results of biochemical tests(ALT and LDT) returned to normal.At the ninth week,most patients' clinical symptoms disappeared.A few patients still had the symptoms of weakness[2(7.14％)] and joint piin[6(21.43％)].Conclusions After effective treatment,antibody titer of patients decreases rapidly,at the same time,the clinical symptoms improve quickly.There is a parallel relationship between the change of antibody titer and clinical symptoms.It is demonstrated that the appearing time of brucellosis specific antibodies,the ampfitude and speed of change of antibody titers can be used in diagnosis,therapeutic evaluation and prognosis of the disease.

Objective To observe the clinical features of brucellosis spondylitis and analyse the reasons for its misdiagnosis,and improve the level of diagnosis and differential diagnosis.Methods Forty-two clinically diagnosed patients with brucellosis spondylitis were studied retrospectively,and these patients were diagnosed and hospitalized in the General Hospital of Heilongjiang Land Reclamation Bureau.Their medical records were analyzed,which included the general information,medical history,clinical symptoms,results of magnetic resonance imaging(MRI) and serum tube agglutination test(SAT) and so on.Results Main clinical symptoms and signs were severe persistent neck,back and leg pain.They also had plate shape low back but without kyphosis.In addition,patients had to keep in one posture because their spinal activity was limited.Also,scoliosis or pelvic tilt and lameness may occur when standing,which were typical symptoms of nerve root compression.Thirteen cases were diagnosed as tuberculosis,accounting for 30.95％(13/42); 6 cases were diagnosed as lumbar disc herniation,accounting for 14.28％ (6/42); 2 cases were diagnosed as ankylosing spondylitis,accounting for 4.76％ (2/42).Therefore,the total rate of misdiagnosis was 50％ (21/42).Abnormal MRI signal intensity can be seen in the pathological vertebrae.Specifically,T1-weighted images (T1WI) showed low signal,T2-weighted images (T2WI) showed high signal,or mixed high and low signal intensity was observed.Vertebral showed wedge deformation without collapse and sequestrum; strip and sheet abnormal signal can also be found within the intervertebral disc.Normal structure disappeared and disc space became narrow.Accordingly,the plane dural sac was compressed to form visible abscess near the spine,but psoas abscess was not found.Patients with positive SAT result accounted for 92.85％ (39/42).Conclusion Reasons for misdiagnosis include lack of detailed medical records,atypical clinical symptoms and similar imaging changes and so on.

Objective To establish a multiplex loop-mediated isothermal amplification(mLAMP)method for simultaneous detection of Salmonella,Vibrio parahaemolyticus (VPH)and Listeria monocytogenes (LM).Methods Three sets of mLAMP primers were designed to specifically target bcfD of Salmonella and tlh of VPH and iap of LM.The respective single LAMP assay of the three kinds of bacteria was developed,and the ratio of primer concentration was optimized to develop a multiplex LAMP system.The specificity and sensitivity of multiplex LAMP were observed.Results Turbidity monitoring results in real time suggests that the mLAMP was highly specific and amplification could be obtained within 45 min under isothermal conditions.The sensitivity of this mLAMP was found to be 300 fg/μl genomic DNAs for Salmonella and 4.2 pg/μl for VPH and 4.5 pg/μl for LM,which was consistent with conventional PCR.Conclusion The mLAMP described can potentially facilitate simultaneous detection of three kinds of bacteria in a large number of food samples, which could be used as a primary screening method and as a supplement to classical detection methods.

OBJECTIVETo evaluate the feasibility and safety of nickel-titanium compression anastomosis ring (CAR27) in colorectal anastomosis after low anterior rectal resection in animal models.

METHODSEnd-to-end colorectal anastomosis was performed using CAR27 in 6 experimental pigs after resection of the middle and lower third of the rectum. The animals were observed postoperatively for up to 56 days. Five pigs were sacrificed at day 14 and the other at day 56. Distance from anal verge to anastomosis and anastomotic circumference were measured. Histopathologic examination was performed.

RESULTSThe median distance from anal verge was 5.3(4-6) cm. No anastomotic leak or other complications were observed. All the pigs recovered and gained weight. In 5 animals sacrificed at day 14, the mean circumference of the anastomosis was 6.8(6.5-7.0) cm, and histopathological examination showed mild inflammatory reaction and fibrosis. In the one sacrificed at day 56, the circumference expanded to 9.3 cm, and no inflammation and fibrosis were observed. Minor adhesion was noticed in only one pig, while smooth and intact serosa in the anastomosis was seen in the rest of the animals.

CONCLUSIONCAR27 is a promising device for mid and low colorectal anastomosis.

OBJECTIVETo compare the clinical characteristics of gastric cancer between young and elderly patients,and bring forward corresponding countermeasures.

METHODSClinical characteristics, treatment and prognosis between 79 young (or= 65 years old) patients were compared.

RESULTSThe constituent ratio of gender between young and elderly group was not significantly different (P=0.226). There was no particularity of early symptom in young patients, but they had shorter course of disease (165 d vs 400 d, P=0.029) and more frequent inferior part of cancer (49.4% vs 41.7%, P=0.038) as compared to elderly patients. There was significant difference between two groups in pathological stage ratio (P=0.027). The median total survival time of young and elderly patients was 1006 d and 530 d respectively, which was not significantly different (P=0.108). Furthermore, median survival time of young and elderly patients after radical resection were 1197 d and 919 d respectively, and the difference was not significant as well (P=0.242).

CONCLUSIONSCharacteristics of young patients with gastric cancer are lower incidence, larvaceous symptoms, more malignancy and quick development, which still remain general features of gastric cancer. By correct therapy, the efficacy of above young patients is similar to elderly patients. The key to improve prognosis is to further fortify cognition for gastric cancer and elevate early diagnostic rate.

OBJECTIVETo evaluate the clinical value of (89)SrCl(2) (Ke xing Inc, Shanghai) as a palliative therapy modality for cancer patients with bone metastasis.

METHODSIn 504 cancer patients with painful limitation of movement due to bony metastasis, a dose of 1.48-2.22 MBq/kg (40-60 uCi/kg) iv infusion of (89)SrCl(2) was given.

RESULTSIn 97 patients (19.2%) there was no improvement in pain and life quality, 298 patients (59.1%) showed mild to moderate improvement (moderately effective), 109 patients (21.6%) became free of pain and were subsequently fully ambulatory (markedly effective). The pain relief appeared from D1-D46 after (89)SrCl(2) administration, most frequently from D5-D14. The palliative effect could last for about 56 days to 13 months. Repeated bone scans of some patients showed that the metastatic foci in the bone became smaller or even disappeared gradually after the administration of (89)SrCl(2). Approximately 55% of patients experienced grade I approximately III bone marrow depression attributable to (89)SrCl(2), which would return to the pre-treatment level within 3 approximately 9 months.

CONCLUSION(89)SrCl(2) is effective and safe for the relief of bone pain and improvement of quality of life in cancer patients with painful bony metastasis.

OBJECTIVETo explore the value of application of Bioflex dynamic stabilization system in treating multi-segment lumbar degenerative disease.

METHODSClinical datas of 13 patients with multi-segment lumbar degenerative disease (8 males and 5 females,ranging in age from 51 to 72 year with an average of 65.0) were retrospectively analyzed between April 2008 and May 2009. The involved area included L3-S1 in 7 cases, L2-S1 in 3 cases, L3-L5 in 1 cases, L4-S1 in 2 cases. All patients underwent decompression, dynamic stabilization with Bioflex system, according to the severity of degenerative disc with/without interbody fusion. The clinical effects were evaluated by VAS, ODI. ROM and fusion segments were also observed.

RESULTSThe mean follow up period was 19.5 months (from 12 to 26 months). The mean operative time was 183.4 min (from 90 to 240 min) and the mean volume of blood loss was 610.2 ml (from 400 to 1 220 ml). The mean VAS score was 7.8 +/- 1.3 preoperatively, 2.3 +/- 0.9 postoperatively and 2.1 +/- 0.8 at the last follow up. The average ODI was (60.50 +/- 4.40)% preoperatively, (17.80 +/- 2.10)% postoperatively and (16.20 + 2.40)% at the last follow up. The VAS and ODI significant improved in postoperatively (P < 0.05), and there was no statistical difference between postoperative and last follow up (P > 0.05). ROM of whole lumbar and non-fused segment showed obviously decreased and adjacent segment showed insignificant increased. The fusion rate of interbody fusion level was 95.0% (19/20).

CONCLUSIONThe preliminary clinical results show the Bioflex system combined with intebody fusion is a safe and effective technique in treating multi-segment lumbar degenerative disease.
