Objective To observe the relationship between degree of venous injury and the indwelling time by injection of chemotherapy drugs with intravenous catheter system. Methods Totally 43 New Zealand rabbits were selected as the study sample. Among them, three rabbits were chosen by lot as a blank control, the others were evenly divided into two groups randomly. The veins at the edges of the two ears were taken out as the tested blood vessels for the infusion with intravenous catheter system. The two groups were injected respectively with physiological saline and chemotherapy drugs once daily, and then blocked with heparin salt water. After intraperitoneal anaesthesia, pathological sections were prepared by taking live samples from the ear vein where intravenous catheter system puncturing on the 2nd, 4th, 6th,8th and 10th day of transfusion. And inflammation and thrombosis in the vein had been observed under the light microscope. Results In the same indwelling time, the inflammatory response of the two groups was compared: no difference on the 2nd day; difference was seen on the 4th、6th and 8th day; but again no difference on the 10th day. Thrombosis compared: no difference on the 2nd, 4th day, but difference was seen on the 6th, 8th and 10th day. Conclusions Chemotherapy drugs has a strong irritant on blood vessels.The indwelling time should not be too long, generally advisable 2 days,even if no abnormal response is observed locally by the naked eye.

Objective To establish the rapid pathogen identification method for HIV and Mycobac-terium tuberculosis (Mtb)co-infection and the assay for the drug susceptibility. Methods Geneprobe and 16S rDNA sequencing were used to differentiate mycobacterium species and modified microscopic observation drug susceptibility (MODS) was used for the drug susceptibility test. The above assays were compared with acid-fast smear, L-J culture and proportional drug susceptibility tests. Results (1) Thirty-four mycobacte-rial isolates were obtained from 112 samples collected from 68 HIV patients. Among these isolates, the strain species were determined by Geneprobe and 16S rDNA sequencing as the followings: 21 Mtb complex, 10 NTM including 5 M.avium complex, 2 M.gordonae, 2 M.kansasii, 1 M.colombiense, and 3 co-infection. (2) The sensitivity of Mtb to rifampicin, ethambutol, isoniazid and streptomycin were 100%, 100%, 76.2%, 90.5% respectively, while the sensitivity of NTM to rifampicin, ethambutol, isoniazid and strepto-mycin were 40%, 60%, 0%, 30% respectively. There is no significant statistic difference between the two methods, MODS and the reference standard, for the drug susceptibility test. (3) Six to eight weeks are nee-ded for the identification of the species of mycobacteria and the drug susceptibility test by using traditional method. In this study, 5-14 d, 6-15 d and 10-14 d are needed for Geneprobe, 16S rDNA sequencing, and MODS respectively. The time for the testing has been dramatically shortened. Conclusion The identifica-tion of mycobacterial species and the drug susceptibility test using clinical samples could be completed within 15 days by using combined Geneprobe, 16S rDNA sequencing and modified MODS. This combined method can be used for the pathogen identification and drug resistant test in HIV patients who are co-infected by my-cobacteria.

Objective To improve the diagnosis of tuberculosis ( TB) by analyzing Mycobacterium infection in fine-needle aspiration biopsy specimens from children with tuberculous lymphadenitis .Methods Fine-needle aspiration biopsy was performed on 269 children with tuberculous lymphadenitis diagnosed by Shanghai Public Health Clinical Center from January 2011 to September 2013 .The needle aspiration biopsy specimens were processed for acid-fast bacillus (AFB) smear test, mycobacterial culture and Mycobacterium identification ( p-nitrobenzoic acid inhibition test ) .Results Cytological diagnosis of tuberculous lymphade-nitis was made for 269 patients.The positive results by AFB smear test were detected in 63.19% of 269 specimens (n=170) and 40.15%(n=108) specimens were positive in mycobacterial culture .The differ-ence between the two tests were significant (P<0.01).The positive rate of Mycobacterium detected by using BACTEC MGIT 960 automated system and L?wenstein-Jensen culture method were 38 .66% ( n=104 ) and 28.99%(n=78), respectively, showing the significant difference between two tests (P<0.05).AFB smear test in combination with mycobacterial culture could precisely diagnose 70.63% of tuberculous lym-phadenitis in children.Of the 108 clinical isolates, 105 strains (97.2%) were Mycobacterium tuberculosis complex and the rest were non-tuberculous Mycobacterium strains (2.8%).Conclusion The positive rate by AFB smear test was significantly increased in fine needle aspiration biopsy specimens after a series of treatments including sample digestion , centrifugation and precipitation , but the positive rate of mycobacterial culture was reduced .Diagnostic accuracy could be significantly improved by using BACTEC MGIT 960 sys-tem.Mycobacterium tuberculosis complex was the predominant pathogenic bacterium in children with tubercu-lous lymphadenitis .

BACKGROUND: BALB/c and C57BL/6 mice are two inbred strains, but after voluntary movement, there is no report on how to scientifical y reasonably select behavioral experiment methods and indicators and to evaluate the learning and memory abilities of mice.
OBJECTIVE: To analyze and compare the behavioral indicators between BALB/c and C57BL/6 mice fol owing voluntary wheel running, to explore the effect of exercise on learning and memory, and to provide a reference for selecting reasonable behavioral indicators.
METHODS: 2.5-month-old BALB/c and C57BL/6 mice were randomly divided into control and voluntary wheel running groups. Independent running wheel movement of mice was recorded with VitalView system. 4 weeks later, newborn neurons were labeled via DCX immunofluorescence. Spatial learning, memory and exploration abilities were compared through new arm test, new object recognition test and Morris water maze test.
RESULTS AND CONCLUSION: (1) The mean spontaneous activity of BALB/c mice daily was 2.56 fold of that of C57BL/6 mice during wheel running (P < 0.001). (2) Hippocampal DCX-positive cel s in exercised BALB/c and C57BL/6 mice were more than those in control group. (3) Meantime, exhibited by higher frequencies to explore new arm or object, and longer time and distance of moving around them, the learning and exploring capability was improved after exercising (P < 0.001), especial y in BALB/c mice. (4) Wheel running C57BL/6 mice exhibited progressed spatial learning and memory abilities compared with control mice in Morris water maze test, characterized by decreased latency to target, elevated target crossings and longer time or distance in quadrant zone (P < 0.05). However, there was no significant difference between wheel running and control BALB/c mice. Taken these data together, voluntary wheel running contributed to hippocampal neurogenesis of BALB/c and C57BL/6 mice, accompanied by the change of learning and memory capability, which could be detected properly via both new arm test and new object recognition test, but for Morris water maze test, C57BL/6 mice might be superior to BALB/c mice.

Objective To investigate the problem of adverse effects in common AIDS patients and AIDS patients with tuberculosis after highly active antiretroviral therapy (HAART). Methods The case group was composed of 106 patients with both AIDS and tuberculosis. The control group was composed of 134 common AIDS patients. The rates of adverse effects and the increase of CD4 + T cell count in those groups after first year HAART were observed and compared. Results The rates of adverse effects in the case group was 36. 8% ,which was more than that in the control group (26. 9%), but the difference was not significantly different(x2 =2.715, P =0. 099). The count of CD4+ T cell in most of the patients was increased after HAART (P ＜ 0. 01). The increase of CD4 + T cell count in the case group [(147.2 ±137.6)/μl] was higher that in the control group[(142. 1 ± 127. 0)/μl after six months HAART vs. (166. 5±133. 1)/μl in case group], and it was lower than that in control group after nine months HAART [(172.7±107.5)/μl], however the difference was not significant(P ＞0.05). Conclusions HAARTcould reconstruct the immunition of AIDS patients. The increase of CD4 + T cell count did not show significant difference between common AIDS patients and AIDS patients with tuberculosis after HAART. AIDS patients with tuberculosis might not increase the risk of development of adverse effects during HAART.

Objectives To compare the migrating motor complex (MMC) in irritable bowel syndrome (IBS) patients with that in healthy controls. To explore whether discrete clustered contractions (DCC) are connected with abdominal pain in IBS patients. To improve the method of measuring gastroenteric motility (esp. jejunum). Methods By using 16-channel water-perfused catheter and manometry instruments, MMC in 16 cases of IBS with constipation (IBS-C), 18 cases of IBS with diarrhea (IBS-D) and 18 cases of healthy controls were monitored. Results The MMC durations of IBS-C and IBS-D patients were (127.5±25.5) min and (74.5±18.7) min, respectively. Comparision with those in the control group [(87.5±24.2) min]showed significant differences (P<0. 001). The contraction amplitudes of stage Ⅲ in different sites of IBS-C patients decreased significantly as compared with those in the controls [jejunum, (39.8±11.7) mm Hg vs. (61.1±14.1) mm Hg,P<0.001,1 mm Hg=0.133 kPa]. The propagation velocities of stage Ⅲ in different sites of IBS-C patients also decreased significantly as compared with those in the controls [jejunum, (1.8±0.9) cm/min vs. (2.6±0.8) cm/min,P<0.01].The contraction amplitudes of stage Ⅲ in different sites of IBS-D patients increased significantly as compared with those in the controls [jejunum, (69.7±20.5) mm Hg vs. (61.1±14.1) mm Hg, P<0.01]. The propagation velocities of stage Ⅲ in different sites of IBS-D patients also increased significantly as compared with those in the controls [jejunum, (4.1±2.5) cm/min vs. (2.6±0.8) cm/min, P < 0. 01]. DCC incidences of IBS-C and IBS-D were 87.5% and 88. 8%, respectively. Comperision with those in the normal group (83.3%) did not show significant difference (P>0.05). The prevalences of abnormal stage Ⅲ contractions (include disturbances and interferences of stage Ⅲ contractions) in IBS-C and IBS-D patients were 68.8% and 66. 7%, respectively; there were no significant differences between the two groups (P > 0. 05). However abnormal stage Ⅲ contractions did not exist in healthy controls. Conclusions (1) The MMC of IBS-C and IBS-D patients are changed, as compared with that in healthy people; this implies that small intestinal motility dysfunction is one of the pathogenetic factors of IBS. The abnormal stage Ⅲ contractions in jejunum may be a predominant change in IBS gastroenteric motility. (2) No apparent connection is found between DCC and pain in IBS. (3) By using 16-channel water-perfused catheter, we first carried out the method of monitoring jejunum contractions in China. Parameters of MMC in Chinese healthy people were investigated, esp. those of jejunum.
