Good clinical results were shown in nasopharyngeal carcinoma (NPC) patients received radiotherapy. The patients with long term life partially had radiation induced injuries that severely affect the quality of life (QOL). The study on QOL of those patients is important. Our article reviewed the effects of NPC QOL by treatment options, health education, rehabilitation therapy, traditional chinese medicine and qigong. The current measurement scale of NPC QOL in China was also discussed.

0.05). Conclusion Compared with the Whiteside′s line, the transepicondylar axis seems to be more reliable to determine the rotational alignment of femoral component in total knee arthroplasty. The posterior femoral condylar angle of the Chinese people is larger than that of the Caucasians. If the widely used way of 3? lateral rotational orientation of the femoral component referring to the posterior condylar surfaces of the femur in total knee arthroplasty is adopted, it tends to produce internal malrotation of the femoral prosthesis after operation.

Objective To evaluate the effect of arthroscopic reshaping procedures on symptomatic discoid meniscus and compare the outcomes between children and adults. Methods The medical records of those who had undergone arthroscopic reshaping procedures for symptomatic discoid meniscus between January 1997 to December 2000 were reviewed. Results Fifty-four patients had been followed up more than 7 years, including 38 children and 16 adults. The average Lysholm score increased from (65.0?10.0) preoperatively to (72.0?10.0) postoperatively. The average 8.2-year follow-up showed no obvious clinical symptoms and signs or osteoarthritis in children. Fourteen knees in adults were found osteoarthritis on X-ray film, of which 6 showed the symptoms and signs of osteoarthritis. Conclusion The midterm efficacy of arthroscopic surgery for symptomatic discoid menisci and the occurrence of postoperative osteoarthritis are related to age and injury course.

In this review,concepts concerning etiology and nonoperative and operative treatment methods have been analyzed.This article is based almost exclusively on peer-reviewed studies.The etiology of nontraumatic osteonecrosis of the femoral head may have genetic basis.The interaction between certain risk factors and a genetic predisposition may determine whether this disease will develop in a particular individual.Early diagnosis and intervention prior to collapse of the femoral head is key to a successful outcome of joint-preserving procedures.The rational for use of joint-sparing procedure in the treatment of this disease is based on radiographic measurements and findings with other imaging modalities.The results of joint-preserving procedures are less satisfactory than the results of total hip arthroplasty for femoral head than have already collapsed.New pharmacological measures as well as the use of growth and differentiation factors for the prevention and treatment of this disease may eventually alter our treatment approach,but it is necessary to await results of clinical research with long-term follow-up of these patients.

To investigate the repairing effect of fibrochondrocyte collagen construct in meniscus lesion, fibrochondrocytes were isolated and expanded in vitro , then seeded onto collagen construct .18 dogs with wedged shape lesion in the lateral meniscus were randomly divided into 3 groups: the lesion were filled with either cell collagen construct or collagen or untreated. The lateral meniscus was then examined grossly and histologically at different periods. The results showed that the lesions that had been filled with fibrochondrocyte collagen construct healed with fibrocartilage tissue. The results suggest that tissue engineering method is practical.

To investigate the behavior of meniscal fibrocartilage cells in vitro ,human meniscal fibrocartilage cells were harvested from adolescents and sequentially digestied with 0 50% trypsin and 0 2% collagenase (type2). The isolated cells were cultured in Ham'sF 12 medium and identified by histochemical methods. Cell proliferation, morphology and ultrastructure were observed by phase contrast microscope and electronic microscope. In primarily cultured cells, fusiform cells dominated and they were confirmed by the positive result of immunohistochemical examination for type collagen staining. Our results indicate that it is a simple and highly effective method.

Objective By analyzing the cesarean delivery rate (CDR) and the indications of cesarean section in Jiangsu Province from 2012 to 2014, to find the strategy to reduce CDR.Methods Data of 40 hospitals whose number of delivery was over 2 400 per year from the database of the Quality Control Center of Gynecology and Obstetrics of Jiangsu Province from 2012 to 2014 were selected.The cohort was divided into two groups, one was specialized hospital including 11 maternal and child health hospitals and the other included 29 general hospitals.After analyzing the current status of cesarean section of the whole province, the average CDR and the distribution of the first indications of cesarean section in two groups were compared using Chi-square test.Results The average CDRs at year 2012, 2013 and 2014 were 53.8％(96 347/178 970), 51.8％ (97 509/188 142) and 48.8％(106 323/217 877), which had a trend of decrease (x2=1 026.2, P ＜ 0.01).CDR without medical indications for each year were 15.7％ (28 098/178 970), 15.5％ (29 162/188 142) and 12.8％ (27 888/217 877).The rate had decreased apparently from both 2012 and 2013 to 2014 (x2=217.6, P ＜ 0.01;x2=341.3, P ＜ 0.01).The CDRs of specialized hospitals for year 2012, 2013 and 2014 were 51.2％ (45 496/ 88 916), 50.6％ (45 853/90 607) and 49％ (55 404/113 105), while the CDRs of general hospitals for each year were 56.6％(50 851/90 054), 53.0％(51 656/97 535) and 48.6％(50 919/104 772).Both showed significant decreasing trend (x2=105.8 and 1 215.7, both P ＜ 0.01).The average CDR of general hospitals was obviously higher than that of specialized hospitals in 2012 and 2013 (x2=505.6 and 104.3, both P ＜ 0.01).However, the difference disappeared in 2014 (x2=3.2, P ＞ 0.05).The three main first indications of cesarean section were associated and postoperative pregnancy complications, and no medical indications.Interestingly, from 2012 to 2014, the CDR for scarred uterus in specialized hospitals raised from 5.4％ to 20.3％, and that in general hospitals increased from 6.7％ to 21.6％, which became the first.Conclusions The average CDR in Jiangsu Province tends to decrease each year, so does the CDR without medical indications.The first indication of cesarean section is associated or postoperative pregnancy complications, while scarred uterus becomes the most common in cesarean section.

Objective To explore the differences of the joint function and the patient's satisfaction between two different methods to reconstruct limb length for unilateral Crowe Ⅳ developmental dysplasia of the hip (DDH).Methods The clinical controlled study were used.21 cases with unilateral DDH Crowe Ⅳ treated with total hip arthroplasty were divided into 2 groups randomly.The patients in the first group were reconstructed the limb with the compensatory length and those in the second group were did with the real length.The patients were followed up 10 years.Two independent sample t-test was used to compare these two operations.Harris scores and SF-36 scores were used in the test.Survival analysis with Kaplan-Meier method was involved in the survival of the prosthesis and then test with Log-rank test.X-ray films of different period were compared to confirm the prosthetic loosening.Results Seventeen patients were followed up 8-10 years.There were no significant differences both in Harris score and most of the SF-36 scores at the median follow-up of 10 years.The item mental healthy of SF-36 expressed significant difference.Five patients required revision.There were 10 cases suffered with polyethylene wear,6 cases with severe osteoporosis in greater trochanter,and 3 cases with osteolytic reaction.Conclusion There are no significant differences between the two surgical method in the survival rate of prosthesis and the joint function in the median follow up.The satisfaction of the control groups is lower than the trial groups both at the early stage after the operation and the median follow up.The revision rate between the two groups is similar but the reason is different.
