Objective:To describe the clinical results of a one-stage operation for posterior cruciate ligament reconstruction and a posterolateral corner reconstruction of popliteus tendon reconstruction,com-pared with an open popliteofibular ligament reconstruction.Methods:Our study included 33 patients who had undergone posterior cruciate ligament reconstruction with use of an achilles tendon-bone allograft and posterolateral corner reconstruction with arthroscopic anatomical reconstruction of popliteus tendon or open reconstruction of popliteofibular ligament.The patients were assessed for knee instability with use of the dial test at 30°and 90°,together with posterior stress radiography and KT-1000 measurement.Re-sults:The mean time of follow-up was more than 2 years.At the final follow-up evaluation,the tibial posterior translation as measured by stress radiography at 90°of knee flexion,the anterior-posterior trans-lation as measured by KT-1000,and the external rotation of tibia as measured by dial test were reduced postoperatively (P<0.001 )in both groups.Between the two groups,the preoperative tibial posterior translation as measured by stress radiography and the preoperative mean anterior-posterior translation as measured by KT-1000 in the popliteofibular ligament group were a little more than those in the popliteus tendon group (P=0.014,P<0.001).But the other comparisons were not significantly different (P>0.05).The final flexion losses were 3.33°±4.88°and 3.06°±3.38°for the two groups.Conclusion:Combined with posterior cruciate ligament reconstruction,anatomical posterolateral corner reconstruc-tion of the popliteus tendon and open reconstruction of popliteofibular ligament showed similar out-comes.This study demonstrated that both posterolateral corner reconstruction techniques were a reliable alternative method in addressing posterolateral corner and posterior cruciate ligament insufficiency of the knee.

OBJECTIVETo investigate the effect of the anticoagulants on PRP quality, so as to clarify the appropriate anticoagulant used in PRP production.

METHODSThe microstructure change of platelets collected via heparin, citrate, acid citrate dextrose (ACD) and citrate-theophylline-adenosine-dipyridamole ( CTAD) was observed by TEM following time course. The extent of spontaneous activation of platelets in four groups was detected by measuring sP-selectin in plasma. The TGF-β1 release amount of activated PRP of four groups was measured.

RESULTSCTAD is superior to other anticoagulants in maintaining the integrity of platelet structures for a long time and preventing platelet spontaneous activation. ACD slightly surpassed heparin and citrate in above two aspects. ACD-PRP and CTAD-PRP released significantly more TGF-β1 compared with heparin and citrate.

CONCLUSIONSThe PRP quality and biological effects were strongly associated with the type of Anticoagulants. ACD and CTAD are optimal anticoagulants in PRP production for they can maintain platelet viability at a high level.

Objective:This study was designed to explore the effects and mechanisms of raltitrexed on the growth of the human gastric cancer cell line (MGC-803) transplanted in nude mice. Methods: Models of MGC-803 xenograft transplanted in nude mice were established. Body weight, mental state, food, and stool of the nude mice were closely monitored, and the inhibitory action in the tu-mors was evaluated after drug intervention. Distribution and apoptosis of the tumor cells were examined through flow cytometric assay. P53 mRNA and protein expression levels were determined through reverse transcription-polymerase chain reaction and Western blot analysis. Changes among the three groups were compared. Results:Body weights and tumor volumes of the nude mice were lower in the raltitrexed and 5-fluorouracil (5-Fu) groups than those in the control group. Tumor inhibition ratios were 49.02%and 45.75%in the raltitrexed and 5-Fu groups, respectively. In the G0/G1 stage, the number of cells decreased in the raltitrexed and 5-Fu groups. Signifi-cant differences were found between the experimental and control groups (P<0.01). In the S stage, the number of cells increased in the raltitrexed and 5-Fu groups, with significant differences from the control group (P<0.01). P53 mRNA and protein expression levels in the raltitrexed and 5-Fu groups were significantly higher than those in the control group (P<0.01), but no significant differences were found between the raltitrexed and 5-Fu groups (P>0.05). Conclusion:Raltitrexed can inhibit the growth of MGC-803 xenograft trans-planted in nude mice and shows inhibitory effect similar to that of 5-Fu. Raltitrexed can induce the S-phase block of the cell cycle and cell apoptosis in the MGC-803 xenografts in the nude mice. This drug may exhibit an antitumor effect by upregulating the p53 mRNA and protein expression levels.

Objective To compare in-vitro percutaneous absorption and pharmacodynamic actions of anti-inflammation and inhibiting delayed-type hypersensitivity of Chinese herbal compound cremor for eczema (CHCCE) with different mass concentrations of synthetic borneol. Methods By adopting modified Franz diffusion device add with isolated BALB/cnude mice skin as a barrier, in vitro percutaneous absorption effectiveness of CHCCE with different mass concentrations of borneol was compared by in vitro percutaneous test after the content of matrine was determined with high performance liquid chromatography(HPLC). Meanwhile, the effects of CHCCE with different mass concentrations of synthetic borneol on reducing dimethylbenzene-induced auricular edema and suppressing delayed-type hypersensitivity induced by 2,4-dinitrochlorobenzene(DNCB) in mice were compared. Results Cumulative permeation amount of matrine in CHCCE with synthetic borneol was higher than that in CHCCE without synthetic borneol 2～ 48 h after administration (P < 0.05). There was no significant difference of cumulative permeation amount (P>0.05) among CHCCE groups with different mass concentrations of synthetic borneol after 48 h. In vitro percutaneous absorption behavior of matrine arrived to the steady state and the cumulative permeation amount of matrine presented a decreasing trend in all medication groups 12 h after administration. Within 12 h of the medication, the permeation rate of CHCCE with different mass concentrations of borneol was in the sequence of 3％ borneol > 1％ borneol > 2％ borneol > 0.5％ borneol > no borneol. The content of matrine was decreased with the increase of mass concentration of synthetic borneol after 12 h. The results of pharmacodynamic actions of CHCCE showed that compared with the blank control group, CHCCE with 1％, 3％ synthetic borneol could significantly suppress the acute inflammation induced by dimethylbenzene and inhibit contact dermatitis induced by dinitrochlorobenzene (DNCB) in mice(P < 0.05). Compared with Triamcinolone Acetonide Acetate and Miconazole Nitrate and Neomycin Sulfate Cream, CHCCE with 1％, 3％synthetic borneol could decrease the serum level of IL-4, but the difference was insignificant(P>0.05). Conclusion CHCCE with 1％ synthetic borneol has good effects on in vitro transdermal absorption, and can suppress inflammation and delayed-type hypersensitivity effectively.
