A murine closed trauma model was used to study the modulating effects of macrophages on T lymphocyte proliferation and the mechanism.It was found that the T lymphocyte transformation was significantly lower than the control on the 1st,2nd,4th,7th and 10 day posttrauma and the suppression of macrophages on T lymphocytes was augmented especially on the 1st,2nd and 4th day posttrauma.Interleukin 1 production of macrophages was not obviously changed while tumor necrosis factor and prostaglandin E2 synthesis were significantly increased.Indomethacin 1?g/ml could block the suppression of macrophages on T cell transformation and mitomycin-C 25?g/ml could stop the synthesis of cytokine but could not block completely the suppression on T cell transformation.These findings suggest that closed trauma induced suppression on T cell transformation results from macrophages through the release of large amounts of prostaglandin E2 and direct cell to cell contact.

Objective To design and apply a kind of controllable enema input apparatus in patients with spinal cord injury (SCI). Methods 20 SCI patients with chronic constipation were included. Their defecation time, nature of defecation and usage of enema of 5 times of defecation were recorded before and after using the new apparatus. Results There were significant differences in the defecation time, nature of defecation and usage of enema before and after using the new apparatus (P<0.05). Conclusion The application of the new controllable enema input apparatus may shorten the defecation time, improve the nature of defecation, and reduce the usage of enema in SCI patients with chronic constipation.

OBJECTIVETo compare clinical efficacy of anatomic locking plate and Gamma nail in treating unstable femoral intertrochanteric fractures with external wall fractures.

METHODSFrom June 2010 to June 2014,clinical data of 44 patients with intertroehanteric fractures associated with lateral wall fractures (type 31A2.2-3.3) followed more than 12 months,which treated with Gamma nail or anatomic locking plate,were retrospective analyzed. Sixteen patients were treated with anatomic locking plate, including 6 males and 10 females aged from 32 to 83 years old with an average of 56.5 years old. Twenty-eight patients were treated with Gamma nail including 17 males and 11 females aged from 26 to 87 years old with an average of 60.4 years old. Operative time, intraoperative fluoroscopy times, blood loss (intraoperative and hidden blood loss), hospital stays were observed and compared. PPMS and HHS scoring were used to evaluate postoperative clinical effect.

RESULTSAll patients were followed up from 12 to 24 months with an average of 16.2 months. Operative time in Gamma nail was shorter than anatomic locking plate; while blood loss( intraoperative and hidden blood loss) and intraoperative fluoroscopy times in anatomic locking plate were less than that of in Gamma nail. There was no significant meaning in hospital stays between two groups. Postoperative full weight-bearing time in anatomic locking plate was prolonged than Gamma nail. At the final following-up, PPMS in Gamma nail was 7.50 ± 1.78 and 6.82 ± 1.38 in anatomic locking plate, and there was no obvious meaning between two groups (t = 2.341, P = 0.132); there was no significant differences in HHS score between Gamma nail (83.25 ± 11.18) and anatomic locking plate (86.14 ± 12.36) (t = 1.923, P = 0.243). The incidence of complications in Gamma nail was less than anatomic lock-ing plate (P = 0.005).

CONCLUSIONAnatomic locking plate for intertrochanteric fractures with external wall fractures could avoid re-injury of external wall, especially for severe comminuted fractures, difficult for intramedullary nailing, and there was no significant meaning in hip joint function compared with Gamma nail, while postoperative incidence of complications was higher than Gamma nail, so early weight-bearing was not stress.

Objective To investigate the clinical efficacy of heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine in treating lumbar intervertebral disc herniation. Methods One hundred and twenty patients with lumbar intervertebral disc herniation were randomized to treatment and control groups, 60 cases each. The treatment group received heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine and the control group, heat-sensitive point medicinal moxibustion alone. The VAS score and the JOA Score for Back Pain score were recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results There were statistically significant pre-/post-treatment differences in the JOA Score for Back Pain score and the VAS score in the two groups (P<0.01). There were statistically significant post-treatment differences in the JOA Score for Back Pain score and the VAS score between the treatment and control groups (P<0.01). The excellent and good rate was 80.0％ in the treatment group and 55.0％ in the control group; there was a statistically significant difference between the two groups (P<0.01). Conclusion Heat-sensitive point medicinal moxibustion plus percutaneous administration of tetrandrine is an effective way to treat lumbar intervertebral disc herniation.

Results Of the 117 with ABP,99 cases were mild(MABP)and 18 ones were severe(SABP).The days of relief of abdominal pains,normalization of hepatic function indexes and hospitalization were significantly shorter in ERCP treatment group than that in control group.The complications related to endoscopic therapy were not found.All patients had got followed-up visits for average 20(range 5-37)months(94.0%).The re- currence rate in the ERCP group 0(0/46)were significantly lower than that in the control group 46.8%(29/ 62)(P

Objective To investigate the bacterial distribution and resistance to antibiotic of male urinary tract infections in China,2012.Methods The urine specimens from the tertiary hospitals and the second class hospitals were routinely isolated and identified.Disc diffusion test, MIC test and E -test were used to detect the antimicrobial sensitivity.Results All the clinical stains isolated from 557 tertiary hospitals and 232 second class hospitals.A total of 61293 pathogenic strains were co-llected from male urine specimen, which included E.coli 20357strains ( 33.2%) , E.faecalis 5280 strains ( 8.6%) , K.pneumonia 5249 strains (8.6%) and E.faecium 4516 strains (7.4%).In tertiary hos-pital, The top four bacteria were E.coli, E.faecalis.K.pneumonia and E.faecium, and in second class hospitals were E.coli, P.aeruginosa, K.pneumonia and E.faecalis.The resistant rate of E.coli, K.pneumo-nia and E.cloaecae strains to cefotaxime were above 70%.The resistant rate to levofloxacin were 63.8%, 40.9%and 35.7%, respectively.The 4.2%and 4.0%of E.faecium isolates were resistant to vancomycin and teicoplanin, respectively.The 1.1% and 2.8% of E.faecalis isolates were resistant to vancomyicin and teicoplanin, respectively.Conclusion E.coli were predominant organism in male urinary tract infections in China.There were some difference in bacterial distribution and resistance between the tertiary hospitals and second class hospitals.

OBJECTIVETo study the changes of thrombomodulin(TM) in both plasma and tissue extracts of cancer patients for evaluating its clinical significance.

METHODSPlasma TM levels were measured by enzyme-linked immunosorbent assay(ELISA) in plasma of 188 cancer patients and in 24 cancer tissue extracts including their adjacent normal tissue.

RESULTSThe plasma TM levels both in cancer patients and in metastasis patients were significantly higher than that in controls [(33.47+/-14.25) microg/L/ (41.68 +/-16.96) micro/L, compared with (20.40+/-7.22) microg/L, P<0.01]. The plasma TM levels in cancer patients after operation decreased obviously [(18.45+/-9.96) microg/L, compared with (28.29+/-11.74) microg/L,P<0.01]. Whereas, the plasma TM levels in patients with recurrence and metastasis after operation increased obviously [(34.50+/-12.57 micro/L]. The plasma TM levels in metastasis of lung cancers, gastric cancers and pancreatic cancers were significantly higher than that in non-metastasis (P<0.05 approximate, equals 0.01) respectively, but no significant differences were found between controls and non-metastasis cancers including gastric cancers, pancreatic cancers, nasopharyngeal cancers, large intestine cancers and laryngeal cancers (P>0.05). The TM levels in cancer tissue extracts were significantly lower than that in their adjacent normal tissue extracts [(647.71+/-317.51)) microg/L,compared with (1455.63+/-772.22) microg/L,P<0.01]. On the contrary, the plasma TM levels in these cancers were higher than that in controls.

CONCLUSIONThe rise of plasma TM levels in cancer patients is associated with metastasis and diffusion of cancers. The TM levels can be used as an sensitive index for judging progression and metastasis of cancers.
