Objective To study the expressions of S100A4 and urokinase plasminogen activator(uPA) in pancreatic cancer cells and their correlation with patients prognosis.Methods The expressions of S100A4 and uPA were examined in 63 surgical specimens of primary pancreatic carcinoma by suing immunohistochemistry PV methods,and correlation of their expressions and prognosis of pancreatic cancer was analyzed.Results ( 1 ) Positive immunostaining for S100A4 and uPA was observed in 74.6% (47 cases) and 65.1% (44 cases) of 63 pancreatic cancer samples respectively.(2) The positive expressions of S100A4 and uPA were significantly correlated in pancreatic cancer( P =0.000,r =0.567 ).( 3 ) The expression of S100A4 significantly correlated with TNM stages( P =0.002 ),lymph node metastasis ( P =0.002 ) and distant metastasis ( P =0.007 ).The expression of uPA had a significant correlation with TNM stages ( P =0.002),lymph node metastasis ( P =0.001 )and differentiation(P =0.003).(4) Kaplan-Meier survival analysis showed that the median survival (21 months) of patients with S100A4 ( - ) was significantly longer than the median survival ( 9 months) of the patients with S100A4( + )(P=0.000) ;the median survival(9 months) of patients with uPA( + ) was significantly shorter than the median survival ( 18 months) of the patients with uPA ( - ) ( P =0.000) ; the median survival(23 months)of 13 patients with S100A4( - )/uPA( - )was significantly longer than the median survival of other cases ( Log-rank test,x2 =54.444,P =0.000).( 5 ) Cox regression model ( x2 =53.974,P =0.000 )analysis suggested:the differentiation(P =0.004),lymph node metastasis(P =0.017) 、S100A4( + ) expression ( P =0.000) and uPA ( + ) expression ( P =0.001 ) were independent prognostic factors for pancreatic cancer.Conclusion S100A4 and uPA are highly expressed in pancreatic cancer cells,and S100A4 expression has positive correlation with uPA expression,which indicates that the overexpression of S100A4 and uPA maybe poor prognosis factors for pancreatic cancer patients.S100A4 maybe promote extracellular matrix and basement membrane degradation by up-regulation of uPA protein expression,and ultimately promote tumor invasion and metastasis,which is not favorable to prognosis.They may be potential indicators of metastasis and predictors for prognosis of pancreatic cancer.

Pectin, a polysaccharide extracted from the cell wall of plants, was used as the drug carrier to synthesize the pectin-adriamycin conjugates (P(A)n). The structure of the conjugates was confirmed by UV and IR. The degree of esterification (DE) of the pectin was assessed, and it was found that DE significantly influenced the carboxy group contents, inherent viscosity and galacturonic acid contents of the pectin. The results of drug release test in vitro showed that the conjugate was stable in normal saline, but was gradually enzymolyzed to release the adriamycin in blood plasma and in lymph nodes. The results of lymphatic targeting study of P(A), demonstrated that the modification of DE or drug coupling capacity of pectin significantly influenced the lymphatic targeting characteristics of P (A)n. The adriamycin concentration of lymph nodes was 208 times higher than that of plasma after local injection of the P(A)n, of which the adriamycin content was 27.9% and the pectin was deesterificated 120 minutes by the use of hypothermy alkaline deesterification method.

OBJECTIVE:
To compare the effectiveness of open reduction of posterior cruciate ligament (PCL) avulsion fracture at tibial insertion of knee joint with absorbable screws fixation and absorbable screw combined with suture anchor fixation.
METHODS:
The clinical data of 26 patients with PCL avulsion fracture at tibial insertion who met the selection criteria between March 2015 and October 2021 were retrospectively analyzed. Among them, 14 patients were fixed with simple absorbable screw (group A), and 12 patients were fixed with absorbable screw combined with suture anchors (group B). All patients were confirmed by X-ray film, CT, or MRI preoperatively, and got positive results in preoperative posterior drawer tests. There was no significant difference in gender, age, side of affected limb, time from injury to operation, comorbidities, and preoperative Meyers & McKeever classification, Lysholm score, and International Knee Documentation Committee (IKDC) score between the two groups ( P>0.05). The operation time and postoperative complications were recorded and compared between the two groups. At last follow-up, Lysholm score and IKDC score were used to evaluate the improvement of knee function.
RESULTS:
There was no significant difference in operation time between the two groups ( P>0.05). All incisions healed by first intention, and no complication such as vascular and nerve injury or venous thrombosis occurred. All 26 patients were followed up 9-89 months, with an average of 55.3 months. The follow-up time of group A and group B was (55.7±23.2) and (56.8±29.3) months, respectively, with no significant difference ( t=-0.106, P=0.916). Radiographs showed bone healing in both groups at 3 months after operation, and no complication such as infection and traumatic arthritis occurred. At last follow-up, the posterior drawer test was negative in both groups, and the Lysholm score and IKDC score significantly improved when compared with the pre-operative values ( P<0.05). However, there was no significant difference in the improvement value between the two groups ( P>0.05).
CONCLUSION
For PCL avulsion fracture at tibial insertion of the knee joint, the open reduction and absorbable screw combined with suture anchor fixation can achieve reliable fracture reduction and fixation, which is conducive to the early rehabilitation and functional exercise, and the postoperative functional recovery of the knee joint is satisfactory.
