BACKGROUND:Recently, the number of elder patients with femoral neck fracture increased. It is controversial if patients aged over 75 years should receive total hip replacement or hemiarthroplasty. To select a reasonable surgical manner is of great significance for increasing surgical safety, improving hip joint function, elevating quality of life, decreasing postoperative complications, and reducing revision rate.
OBJECTIVE:To retrospectively analyze data of patients aged over 75 years after hip replacement, to compare the advantages and disadvantages, and to find a precise indication.
METHODS:Case data of 171 patients undergoing total hip replacement (observation group) (n=51) or hemiarthroplasty (control group) (n=120) were included. Their differences were compared using basic diseases, operation time, bleeding amount, postoperative complications, postoperative hospitalization day, Harris score at 1 week and 3 months after operation.
RESULTS AND CONCLUSION:Patients in both groups were fol owed up for 3 to 39 months (averagely 23 months). No significant difference in basic diseases, average age, postoperative complications, postoperative hospitalization day, and Harris score at 1 week was detected between the two groups (P>0.05). Harris score and excellent and good rate at 3 months were better in the total hip replacement group than that in the hemiarthroplasty group (P<0.05). Results indicated that strict choice of indication achieved good short-period efficiency in two groups. Thus, hip function of elder patients was early recovered. Quality of life was obviously elevated. The recovery of hip function was relatively better at 3 months in observation group. The incidence of postoperative complications did not increase obviously. These results suggested that besides sufficient preparation, total hip replacement should be the first choice for elder patients.

Objective: To study the optimal combined ratio of baicalin, icariin and Astragalus saponin I from a Chinese herbal compound Biminne. Methods: Firstly, a mouse model of allergic rhinitis was established by intraperitoneal injection of ovalbumin (OVA) and aluminum hydroxide gel suspension, and the effective dose range of baicalin, icariin and Astragalus saponin I was detected by 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide inner salt method. Secondly, 10 groups of combinations of baicalin, icariin and Astragalus saponin I assembled by U*(10)(10(8)) form were employed to determine the optimal combination by means of analyzing of the inhibitory effect on the splenocyte proliferation. Finally, the effects of each effective ingredient and the optimal combination were compared by observing the splenocyte proliferation, the contents of interleukin-4 (IL-4), IL-5, interferon-gamma (IFN-gamma) in supernatant of the splenocyte cultures and the ratio of IL-4 to IFN-gamma in order to verify the result. Results: Baicalin or icariin at concentrations ranging from 2 to 10 mumol/L, and Astragalus saponin I from 1 to 10 mumol/L effectively suppressed the splenocyte proliferation. When the proportion of baicalin, icariin and Astragalus saponin I was 1:2.14:2.65, the inhibitory effect was most remarkable. Further research confirmed the rationality of the optimal combination. Conclusion: An optimal combination of the major effective ingredients from Chinese herbal compound Biminne most effectively suppresses the proliferation of splenocytes from sensitized mice and regulates the cytokine secreting.

BACKGROUND:Differences of knee anthropometry between individuals are significant, while preoperative templating is not accurate in predicting the prosthesis size.
OBJECTIVE:To improve the accuracy of pre-operative plan in predicting the prosthesis size in total knee arthroplasty using digital technologies.
METHODBetween January 2013 and May 2004, 50 patients (20 men and 30 women;aged 54-82 years;mean age, 67.8 years) received primary total knee arthroplasty for osteoarthritis and were retrospectively analyzed. According to the treatment, the patients were divided into two groups. The digital group, a series of 21 patients, underwent 64-row MDCT before total knee replacement. CT images were imported into Mimics, and three-dimensional models of femur and tibia were reconstructed. Then, computer-aided design files of different sizes of prostheses provided by the manufacturers were imported into Mimics, too. Surgical simulation of osteotomy and prostheses implantation were performed in Mimics, component size was determined by the contour of distal femur and proximal tibia. The control group, a series of 29 patients, underwent primary total knee arthroplasty using conventional approaches. The agreement between preoperative plan and the actual prosthesis size was assessed during the surgery. Postoperative X-ray of low limb was taken to evaluate the accuracy of sizing and the efficacy of digital technologies was assessed.
RESULTS AND CONCLUSION:The intraoperative and postoperative evaluation showed inaccurate sizing of femoral and tibial components in 1 case in digital group and in 11 cases in conventional group. The accuracy of prediction was 95%in digital group and 62%in conventional group, with significant differences between the two groups (P<0.05). Four overhanging and two notching cases were observed in conventional group, but none in digital group. The digital technologies provide an effective means for accurate prediction of prosthesis size and personalized surgical simulation.

OBJECTIVE:
to explore the relationship between the maxillary sinus volume and the amount of alveolar bone, and the effect of molar loss upon the maxillary sinus was further analyzed,by measuring adult maxillary sinus volume, sinus ridge distance, and calculating the gasification coefficient of maxillary sinus.
METHOD:
One hundred and ninety cases (361 maxillary sinus) with CT examinations were collected, they were divided into group A and group B, 121 cases (242 maxillary sinus) of normal subjects served as group A, 42 cases (65 maxillary sinus) with molar part off were B group, in which 31 maxillary sinus with a molar loss were group B1,22 maxillary sinus with two molar loss were B2 group,12 maxillary sinus with three molar loss (one molar remains) were B3 group, 27 cases (54 maxillary sinus) with upper teeth off were C group. Bymeasureing the maxillary sinus volume, sinus ridge distance and the size of the maxillary sinus, calculating the gasification coefficient, we analyzed the relationship between maxillary volume and sinus ridge distance, and comparatively analyzed the differences among the three groups in the size, gasification coefficient, volume of maxillary sinus and sinus ridge distance.
RESULT:
In the normal group,the volume of maxillary sinus and sinus ridge distance had a correlation coefficient of -0. 63,(P< 0.05); Sinus ridge distance in group A was larger than the other two groups (P<0.05), and larger in B group than in C group (P<0. 05), anteroposterior maxillary sinus diameter and reft-right diameter in C group was greater than in A group and B group(P<0.05), group C gasification coeffiecent was less than A group and B group (P<0. 05).
CONCLUSION
The volume of maxillary sinus is negatively correlated with the amont of alveolar bone; Upper teeth's shedding promotes maxillary sinus deformation; Maxiuary sinus volume has a tendency to decrease.
