Data of 39 patients (51 knees) undergoing total knee arthroplasty (TKA) in the Department of Orthopaedics,Fourth Affiliated Hospital of Guangxi Medical University between October 2001 and March 2008,were analyzed retrospectively,including 6 males (6 knees) and 33 females (45 knees) aged 59-72 years. Among the 39 cases,there were 35 cases of osteoarthritis,2 of rheumatoid arthritis,1 of osteoarthritis and pigmented villonodular synovitis,and 1 of advanced tuberculosis. Different degrees of pain,swelling,genu valgum,genu varumand and functional impairment of knee joints were found in all cases. The prosthesis adopted included 3 knees of DePuy,10 of Stryker,3 of Link,5 of Zimmer,7 of Taiwan Unite,and 23 of Pulus (made in China). Among all the cases,47 knees were treated by posterior stabilized prosthesis,and 4 knees were treated with posterior cruciate ligament-retaining TKA. Careful medical examination and evaluation were performed to control blood sugar level before operation; the operation duration was shortened as possible. Reasonable proposals were formulated to prevent the postoperative infection and deep venous thrombosis. Clinical data were analyzed using the HSS score standard. All patients were followed up for 6-57 months. No deep infection,prosthetic loosening or death was found. Postoperatively,2 patients (2 knees) developed cutaneous necrosis at incision margin,of which 1 patient (1 knee) was cured by changing dressings,and 1 patient (1 knee) was healed after incision of skin and relaxation suture. The range-of-motion of 51 knees all exceeded 90?. The motion of knee joint were increased from 65?(32?-95?) in average preoperatively to 96?(90?-110?) after the operation. The preoperative pain of all patients disappeared instantly after operation,beside one case (2 knees) and the other had a little pain. The Harris knee joint scores were increased from 39 points (25-53 points) in average preoperatively to 91 points (82-97 points) after the operation at the final follow-up; 25 cases (34 knees) were excellent,12 cases (15 knees) were good,2 cases (2 knees) were fair and the excellent and good rate was 96%. Although TKA has a satisfactory surgical effect,associated factors should be paid more attention.

Objective To explore the effect of the application of cervical loop electric knife (LEEP) in the patients with cervical micro invasive cancer.Methods Clinical data of 66 patients with minimal invasive carcinoma diagnosed by LEEP cone resection in our hospital from June 2013 to June were retrospectively analyzed. Preoperative and postoperative patients with LEEP were compared with 66 patients who underwent biopsy with biopsy, the diagnosis of micro invasive carcinoma was compared with LEEP cone resection.Results The results of colposcopy biopsy were detected in 2 cases of LSIL, 60 cases of HSIL and 1 cases of AIS, 3 cases were diagnosed as cervical microinvasive carcinoma or suspicious cervical microinvasive carcinoma, the sensitivity was 4.54%, the misdiagnosis rate was 95.46%; LEEP conization were detected in 1 cases of LSIL, 44 cases of HSIL and 1 cases of AIS, 20 cases negative margin. There was no significant difference in the thickness and area of the resected tissue between the three groups (P > 0.05). The depth of the resected tissue was significantly higher than that in the HSIL and AIS group, the HSIL and AIS groups were significantly higher than the LSIL group, the difference was statistically significant (P < 0.05). Interstitial infiltration depth is less than or equal to 1mm group, the 1 depth of stromal invasion than 3mm group and 3 < rate were 15.00%, 19.51% and 20.00% of the remaining lesion depth of stromal invasion than the patients in the 5mm group after operation, there was no statistically significant difference (P > 0.05). Cut edge positive group, positive margin group and interstitial fiber positive margin group of patients with postoperative residual disease rates were 25.00%, 15.38% and 23.80%, the difference was not statistically significant (P > 0.05).Conclusion The rate of missed diagnosis of small invasive cervical cancer is higher, and the diagnosis rate can be improved by the combination of LEEP and cone resection.

Objective To evaluate the therapeutic effect of Xiaoying Ruanjian Decoction on experimental autoimmune thyroiditis (EAT) from the levels of autoantibodies, interleukin-1, tumor necrosis factor-? and apoptosis-regulated proteins Fas/Fasl of EAT rats, and investigate the mechanism from the relation between cytokines and apoptosis-regulated proteins. Methods Sixty SD female rats of SPF level were divided into normal group and model group. An animal model of EAT in rats was developed by injecting thyroglobulin mixed with Freund’s adjuvant immunization and drinking periodate water. The rats modeled were divided into Chinese medicine group, western medicine group and model group. The levels of autoantibodies, interleukin-1, tumor necrosis factor-? were detected with enzyme-linked immunosorbent assay. The level change of Fas/Fasl in the thyroid of rat was observed with immunohistochemical staining. Results Ruanjian Xiaoying Decoction significantly reduced the levels of autoantibody, interleukin-1, tumor necrosis factor-? and lowered the expression of Fas and Fasl in thyroid cells. Conclusion Ruanjian Xiaoying Decoction alleviates the levels of apoptosis-regulated proteins Fas/Fasl by decreasing the relative expression of antibodies and cytokines in serum levels, which plays a role in reducing apoptosis of thyroid cells.

Objective:To compare the social adaptability of Chinese and Japanese children Method:306 preschool children in Xi'an and 215 Japanese children were sampled The research instrument was the Infant-Junior Middle School Social Adaptive Capacity Scale Result:In the six fields of social adaptability, Chinese children had lower scores than Japanese children, except for that of sports Conclusion:Chinese preschool children have lower social adaptive capacity, which may be due to the overprotective attitude of Chinese parents or grandparents

One case with dedifferentiated liposarcoma in proximal tibia accompanied by angiosarcoma was analyzed. The dedifferentiated liposarcoma was further analyzed by imaging, clinical and pathological features. One 51-year-old male patient was suspected to bone tumor due to space occupying lesion for 6 days in left proximal tibia and admitted in Changhai Hospital of Second Military Medical University of Chinese PLA in May 2007. The clinical features, including onset features, physical examination, blood routine, imaging alterations, pathological characteristics, operation approach, and follow-up period were retrospectively analyzed. The tumor was treated by curettage and inactivation, iliac grafting, bone cement filling, tibial plateau T type plate and screw internal fixation and tumor tissue biopsy. However, tumor relapsed 40 days postoperatively, and the patient was treated by amputation surgery. Two weeks after surgery, the patient developed emptysis and died due to multiple organ failure. Dedifferentiated liposarcoma accompanied by angiosarcoma displays no noticeable characteristics in imaging, clinical manifestation, and laboratory examination, which make it difficult to diagnose it. This tumor is highly malignant, and has short disease course, and poor prognosis.
