BACKGROUND: Self-healing ability of the posterior cruciate ligament is poor, and the degradation and synthesis of extracellular matrix often follow the ligament repair. The matrix metalloproteinase family plays a critical role in the dynamic equilibrium between the matrix degradation and synthesis. OBJECTIVE: To investigate the effect of arthroscopic reconstruction of the posterior cruciate ligament, and to study its correlation with matrix metalloproteinase 2 level. METHODS: Sixty patients with posterior cruciate ligament rupture were studied, including 37 cases of autologous reconstruction and 13 cases of allogeneic reconstruction. Ligament and synovial cells from traumatic amputation patients with no ligament injury in the corresponding period were collected. Lysholm and Tegner scores were detected before and after operation. The results of postoperative drawer test were analyzed. The tibial displacement of the posterior cruciate ligament after autologous reconstruction and allogeneic reconstruction was compared. The posterior cruciate ligament cells were cultured alone or co-cultured with synovial cells, and then the level of matrix metalloproteinase 2 protein was detected. In addition, operation time, incision length, postoperative fever time and gender differences were also detected and compared.RESULTS AND CONCLUSION: Tibial displacement, irrespective of genders, was higher in the allogeneic reconstruction group than the autologous reconstruction group, while there were no significant differences in the posterior drawer test between the two reconstruction groups as well as between males and females. Postoperative Lysholm and Tegner scores were both improved significantly (P < 0.01). As time went by, the level of matrix metalloproteinase 2 had an increasing trend in the posterior cruciate ligament cells cultured alone or co-cultured with synovial cells, but the level in the co-culture group was higher than that in the single culture group. For both male and female, the autologous reconstruction group showed a longer operative time (P < 0.05 or 0.01) and a longer incision length (P < 0.01), as compared with the allogeneic reconstruction group, while the time of fever was significantly longer in the allogeneic reconstruction group (P < 0.01). Results from the last follow-up show that the autologous reconstruction is better than the allogeneic reconstruction to restore the stability of posterior cruciate ligament and shorten fever time, but longer operative time and surgical incision as well as increased level of matrix metalloproteinase 2 cannot be ignored.

BACKGROUNDMurine cytomegalovirus (MCMV) early protein M112-113 is involved in viral DNA replication and believed to play a crucial role in the viral pathogenesis. To investigate the biological function of M112-113 protein in the pathogenesis of the brain disorders caused by cytomegalovirus (CMV), a screening for proteins interacting with M112-113 was performed by a yeast two-hybrid system.

METHODSBait plasmid pGBKT7-M112-113 was constructed and transformed into AH109 yeast. After confirmation of the expression of MCMV M112-113 in yeast, the bait yeast was mated with a prey yeast containing mouse brain cDNA library plasmid to screen the proteins interacting with M112-113. Interactions between M112-113 and the obtained proteins were verified by yeast two-hybrid assay and chemiluminescent co-immunoprecipitaion.

RESULTSTwo proteins interacting with M112-113 were identified, including metastasis-associated 1 (MTA1) and zinc finger, CCHC domain containing 18 (ZCCHC18). M112-113 protein could interact with MTA1 or ZCCHC18 in yeast and mammalian cells.

CONCLUSIONThe interactions of M112-113 with MTA1 or ZCCHC18 may be related to the pathogenesis of MCMV-associated disease in central nervous system.

Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG).However,the dynamic process and mechanism of fluorescenceIOC have not been elucidated in previous publications.Herein,the optical properties of the complex of ICG and bile,dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated.The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration.Extrahepatic bile ducts could fluoresce 2 min after intravenous injection,and the fluorescence intensity reached a peak at 8 min.Inaddition,biliary dynamics were observed owing to ICG excretion from the bile ducts into the duodenum.Quantitative analysis indicated that ICG-guided fluorescence IOC possessed a high signal to noise ratio compared to the surrounding peripheral tissue and the portal vein.Fluorescence IOC was based on rapid uptake of circulating ICG in plasma by hepatic cells,excretion of ICG into the bile and then its interaction with protein molecules in the bile.Moreover,fluorescence IOC was sensitive to detect bile duct ligation and acute bile duct perforation using ICG in rat models.All of the results indicated that fluorescence IOC using ICG is a valid alternative for the cholangiography of extrahepatic bile ducts and has potential for measurement of biliary dynamics.

OBJECTIVETo observe the expression of Clara cell secretory protein(CCSP) in the Kunming mouse model of n-hexane long-term inhalation, and to discuss the functions of Clara cell in injury lung induced by n-hexane.

METHODS24 healthy mice were randomly divided into 4 groups: one control group and three n-hexane groups (4 w, 8 w and 12 w), 6 each group. Primary concentration of n-hexane was 17.6 g/m3, 8 hours per day, 6 d per week. After inhalation, n-hexane concentration of blood from celiac artery was detected. The lungs were embedded with paraffin and HE staining in the routine. The ratio of Clara cells with CCSP reaction in bronchiole and the number of macrophage cells with lysozyme reaction were determined by immuno-histochemistry.

RESULTSIn the poisoning groups, the average n-hexane concentration of blood was significantly higher than that of the control group (P < 0.01). There were apparent pathologic damages in lungs of the poisoning mice. In poisoning 4 w, 8 w and 12 w groups, the ratio of Clara cells was significantly decreased [(73.33 +/- 4.21)%, (60.98 +/- 4.94)%, (34.04 +/- 2.33)% in terminal bronchiole, and (75.44 +/- 7.91)%, (58.54 +/- 4.86)%, (33.35 +/- 2.67)% in respiratory bronchiole] as compared with the control mice [(80.26 +/- 6.43)% and (81.74 +/- 7.75)%, P < 0.05 or P < 0.01], meanwhile the numbers of macrophage cells were gradually increased [(21.39 +/- 7.41), (28.54 +/- 10.73), (48.97 +/- 19.55) per microscopic field at 200x] in poisoning mice than those in control mice [(7.84 +/- 3.12) per microscopic field at 200x, P < 0.05 or P < 0.01].

CONCLUSIONIn injury lungs after n-hexane inhalation, Clara cells are the target cells of n-hexane toxicity effect. Clara cells play an extensive protective role in lung inflammation.

Objective:To evaluate the hemostatic effects of our self-designed pelvic band with inflatable balloon in a swine model of hemodynamically unstable pelvic fracture.Methods:"Open-book like" fractures were created with the external iliac blood vessels exposed in 24 12-month-old female Bama miniature pigs which were randomly divided into 4 groups ( n=6). Group C (the control group) was subjected to no treatment other than exposure of the external iliac blood vessels, group D to no treatment following destruction of the external iliac blood vessels, group T1 to fixation with simple pelvic band after destruction of the external iliac blood vessels, and group T2 to fixation with our self-designed pelvic band with inflatable balloon after destruction of the external iliac blood vessels. The 4 groups were compared in terms of 40-min survival rate, bladder pressure, peak lactate value, total blood loss, bleeding rate, infusion rate, and angiographic images. Results:There was no significant difference in the baseline indexes among the 4 groups before experiment, showing comparability ( P>0.05). The 40-min survival rate in group T2 was 83.3% (5/6), significantly higher than that in groups D and T1 [0% (0/6) and 0% (0/6)] ( P<0.05). There were no significant differences among groups C, D, T1 and T2 in bladder pressure [(6.67±1.03) mmHg, (5.83±1.94) mmHg, (6.00±1.55) mmHg, and (6.00±1.10) mmHg] or in total blood loss among groups D, T1 and T2[(1,198.0±182.9) mL, (1,252.0±148.4) mL, and (1,150.0±125.7) mL] (all P>0.05). The peak lactate value in group T2 [(2.26±0.24) mmol/L] was significantly lower than that in group D [(5.00±0.60) mmol/L] and group T1 [(3.86±0.57) mmol/L], and the bleeding rate and infusion rate in group T2 [(25.83±5.49) mL/min and (26.00±4.69) mL/min] were also significantly lower than those in group D [(83.50±19.85) mL/min and (71.50±29.11) mL/min] and group T1 [(54.17±15.59) mL/min and (54.17±8.98) mL/min] (all P<0.05). Angiography showed contrast agent extravasation in group T2, especially from the artery, but the extravasation speed in group T2 was significantly slower than that in group D. Conclusion:In a swine model of hemodynamically unstable pelvic fracture, our self-designed pelvic band with inflatable balloon has a definite hemostatic effect on vascular injury which is better than that of a simple pelvic band.
