Objective To report the technique of functional reconstruction for knee joint following destructive injury and its outcome. Methods In the period from June 1991 to April 2001, microsurgery was done for 4 cases to reconstruct functions of the damaged knees. The operations were combined with transplantation of bilateral latissimus dorsi myocutaneous flaps, emergency transplantation of latissimus dorsi myocutaneous flap, emergency transplantation of useless leg composite tissue and emergency rotation- plasty, respectively. Results All the transplants survived completely. The follow- ups, ranging from 4 to 14 years, revealed normal or nearly normal functions in all the repaired knees. Conclusion Whenever possible, a knee with destructive injury should be repaired and reconstructed, and microsurgery may offer an effective solution.

Background and purpose:Runt-related transcription factor 3 (RUNX3) has a signiifcant relation with gastric cancer. Many researches have confirmed that rs760805 AA can increase the risk of gastric cancer. The purpose of the study was to investigate the relationship between the rs760805 polymorphism of the RUNX3 gene and gastric cancer. Methods: The rs760805 genotypes were determined by PCR-based DNA sequence measuring analysis and direct DNA sequencing in 310 incident cases with gastric cancer and 327 controls recruited in Shandong. Results:The frequency of TT genotype was 15.16%in gastric cancer patients and 20.49%in normal controls, and the corresponding percentages for AT and AA genotypes were 48.39%and 36.45%, and 52.60%and 26.91%, respectively. Compared to TT genotype, AT genotypes were associated with an increased risk of gastric cancer (OR=1.24, 95%CI`:0.81-1.92;OR=1.83, 95%CI:1.15-2.92). Conclusion:The rs760805 polymorphism of the RUNX3 gene is associated with increased susceptibility to gastric cancer.

Objective Ultrasonongraphy and mammography were employed to estimate the pathological response of patients with breast cancer ,who had been accepted neoadjuvant chemotherapy .According to the pres-ent study ,we can provide additional evidence on therapeutic effect on evaluation of neoadjuvant chemotherapy and better selection of regime for breast cancer .Methods One hundred Thirty-six patients who were previously dia-gosed diagnosed with primary breast cancer were included in this study .All subjects were female with clearly pathological detection and accepted neoadjuvant chemotherapy about 4 to 6 cycles regardless of regime .The resid-ual tumor size was evaluated by mammography and /or ultrasonography before operation .Tumor size measured by image were compared with pathological size to predicting the accuracy of two types of imaging .Results Forty one of 116 records were undetectable imaging by mammogram and 19 of 106 records were undetectable by ultrasound which were considered a pathologic complete response .Sixty one(62.24%)of 98 patients who were accepted de-tection of mammogram and ultrasound would be predicted the tumor size by mammogram .Eighty three(84.69%) of 98 patients would be predicted the residual tumor by ultrasound .31 and 59 were accurately evaluated by mam-mogram and ultrasound , respectively .The result indicated that ultrasound was more accurate than mammogram (60.20%vs.31.63%,χ2 =16.11,P<0.001).The correctly rate was 92.85%(91/98)for ultrasound and 68. 37%(67/98) for mammogram.The diagnosis efficiency of ultrasound was more higher than mammogram ,even though there was no different significance between the two methods (χ2 =2.028,P=0.164).Conclusion Ultra-sonongraphy in estimating the residual tumor size after neoadjuvant chemotherapy of patients with breast cancer displays more accurately than mammography .

OBJECTIVE:To evaluate the clinical efficacy of Shuanghuanglian injection in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD),and to observe its effects on the plasma levels of C-reactive protein (CRP),procalcitonin(PCT)and interleukin-6(IL-6). METHODS:A total of 100 AECOPD patients were randomly divided into observation group and control group,with 50 cases in each group. Control group received routine treatment,such as controlled oxygen therapy,intravenous dripping of moxifloxacin,bronchodilator for relieving asthma,mucolytic for eliminating phlegm,nu-tritional support. Observation group was additionally given Shuanghuanglian injection 1 ml/(kg·d)added into 5% Glucose injec-tion 250 ml intravenously,qd,on the basis of control group. Treatment course of 2 groups lasted for 10 d. Clinical efficacies of 2 groups were compared as well as the changes of serum levels of CRP,PCT and IL-6 before and after treatment and the occur-rence of ADR. RESULTS:After treatment,total effective rate of observation group was 96.0%,which was significantly higher than 82.0% of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in se-rum levels of CRP,PCT and IL-6 between 2 groups (P>0.05). After treatment,serum levels of CRP,PCT and IL-6 were de-creased significantly in 2 groups,and those of observation group were significantly lower than those of control group,with statis-tical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CON-CLUSIONS:Shuanghuanglian injection can effectively improve serum inflammatory factors of AECOPD patients,and shows good clinical efficacy and safety.

The introduction of highly active antiretroviral therapy (HAART) has greatly changed the pattern and natural history of ocular diseases of HIV-infected patients, resulting from the immune recovery and reduction of opportunistic infections. However, ophthalmic complica-tion continues to be concern in AIDS even in the HAART era, especially in developing areas, where absolute majority of HIV-positive patients live. Lack of test facilities and experience, poor conditions of hygiene, different microbiological environment, absence of effective treatment etc., characterize the ophthalmic manifestation of HIV-infected patients in developing countries from that in developed regions and thus pose a great challenge to the ophthalmic treatment in developing area. Not only varied from region to region, ocular complications are distinctive between adults and children. At the same time, the side effects due to the application of HAART pose their own risks of ocular complication and should, therefore, be given more research attention.
