BACKGROUND:Total knee arthroplasty had been generaly accepted as the final treatment plan, relieving pain and reconstructing function of knee joint. However, whether drainage tube can be used after replacement is stil controversial.
OBJECTIVE:To compare the clinical effects of drainageversusnondrainage after primary unilateral total knee arthroplasty.
METHODS:Total 102 patients undergoing primary unilateral total knee arthroplasty were randomly divided into 2 groups. In the drainagegroiup, a drainage tube was used. In the nondrainage group,
drainage tube was not used. Total blood loss was calculated by recording the hemoglobin and hematocrit before operation and that after 1, 3, 7 days of operation. The pain visual analogue scale scores, arthrocele, ecchymosis, infection rate, and deep venous thrombosis of lower extremity were examined and analyzed postoperatively. Knee Society Scores were recorded at 1 year postoperatively. Above indexes were compared between the two groups.
RESULTS AND CONCLUSION:(1) Total blood loss and blood transfusion rate were significantly higher in the drainage group than in the nondrainage group (P< 0.05). (2) There was no statisticaly significant difference in the pain visual analogue scale scores, arthrocele, ecchymosis, infection rate, and deep venous thrombosis of lower extremity between the two groups after replacement (P> 0.05). (3) No significant difference in Knee Society Scores was detected between the two groups (P> 0.05). (4) Results indicated that the total blood loss and blood transfusion rate may decrease significantly in patients without wound drainage after total knee arthroplasty. Limb sweling and ecchymosis area were not increased. No significant difference in infection, deep venousthrombosis of lower extremity and knee function was detectable between the two groups. Thus, total knee arthroplasty without wound drainage is safe and does not have obvious adverse consequences.

Objective To investigate the effects of a variety of different methods of analgesia on postoperative pain and cognitive function in elderly esophageal cancer patients.Methods Sixty elderly pa-tients scheduled for the left into the thoracic esophageal cancer surgery were randomly divided into two groups (n =30).Group A:Before the closure of thoracic cavity to block intercostal nerve with 0.375% rop-ivacaine,followed by intravenous pumps for analgesia,formulation of sufentanil 3 μg/kg+flurbiprofen 100 mg,pump speed 2 ml/h,self-controlled analgesia 0.5 ml/pressing,locking time 15 min.Group B:Before the closure of thoracic cavity given sufentanil 10 μg+flurbiprofen 50 mg as loading dose followed by epidural analgesia pump,recipe with group A.Two groups were observed mini mental state examination (MMSE) score 1 d before surgery and 3,5,7 d after surgery,each time point visual analogue pain score (resting and exercise VAS)score postoperative within 48 h,BCS comfort score and effective pressing times of postopera-tive analgesia pump.Results Compared with group B,the rest and exercise VAS scores of group A at post-operative recovery,4,8,12,24,48 h were significantly lower (P <0.05);the BCS scores of group A at postoperative 4,8,12,24,48 h were significantly higher (P <0.05);the pressing times of group A at postoperative 4,8,12,24,48 h were significantly reduced (P <0.05);the MMSE scores of group A at postoperative 3,5,7 d were significantly higher (P <0.05);the incidence of POCD of group A on postop-erative 3,5,7 d were significantly lower.Conclusion Thoracic surgery perioperative multimodal analgesia (intercostal nerve block and intravenous analgesia)can relieve postoperative pain,reduce the incidence of POCD,improve the postoperative patient comfort and help postoperative patients with rapid recovery.

Objective To investigate the neuroprotective effects of phycocyanin injection by internal carotid artery in acute cerebral ischemic reperfusion in rats.Methods The model of middle cerebral artery occlusion reperfusion(MCAO/R) was established using the intraluminal filament occlusion with 84 healthy adult male Wistar rats,and treated by phycocyanin injection through internal carotid artery.The nervous function scores,brain water content,cerebral infarction volume and cell apoptosis in brain tissues and the phycocyanin effects on above indexes were measured respectively.Results The rats showed some extent of neurobehavioral function disorders after ischemic reperfusion.In phycocyanin group rats,the nervous function scores,brain water content,cerebral infarction volume and the number of apoptotic cells in cortex,striatum and hippocampus reduced significantly compared to the model group.Conclusion phycocyanin injection through internal carotid artery showed obvious neuroproctective effects in acute cerebral infarction in rats.

Objective To study the T cells lineage polymorphism of TCR BV CDR3 in the peripheral blood of ankylosing spondylitis (AS) patients,in order to provide experimental basis for the immunological patho-genesis study of AS.Methods Twenty-six subfamilies of CDR3 T cells of TCR BV in the PBMC of AS patients were amplified by RT-PCR method,then TCR BV CDR3 lineages polymorphism were analyzed by immunization scanning spectrum.Results TCR BV CDR3 scanning spectrum of 20 active AS patients showed abnormal distribution peak,including monoclonal,oligoclonal/oligoclonal trend,skewing peak and irregular abnormal peak.Among them,some subfamilies of 18 patients showed oligoclonal/oligoclonal trend expansion,BV16 and BV18 two subfamilies of one case showed monoclonal expansion.Most spectral type of PBMC TCR BV CDR3 in five normal controls showed Gauss distribution.Conclusion TCR BV CDR3 lineage have significant characteristic polymorphism and spectrum drift characteristics in the peripheral blood of AS patients,which further indicate that T cells has plaied an important role in the immunological pathogenesis of AS.Monoclonal/oligoclonal expansion of T cells may be autoreactive T cells in nature and they may be involved in the pathogenesis of AS.

AIM: To investigate the role of staphylococcal enterotoxin B (SEB) in early intestinal injury in scald rats with Staphylococcus aureus sepsis. METHODS: 86 male Wistar rats were randomly divided into four groups as follows: normal controls ( n= 10), scald control group( n= 10), postburn sepsis group( n= 50) and SEB monoclonal antibody (MAb)treatment group ( n= 16). Plasma samples were collected to determine SEB, endotoxin, tumor necrosis factor-? (TNF-?) and interferon-? (IFN-?). RESULTS: After scald injury followed by Staphylococcus aureus challenge, the levels of SEB, TNF-? and IFN-? in plasma were significantly higher than those of normal controls, peaking at 2-6 h ( P

Objective To identify the relationship between sorafenib's efficacy and its side effects in treatment of advanced renal cell carcinoma patients. Methods Fifty-one patients having measurable diseases were diagnosed with advanced renal cell carcinoma. Of whom, 26 patients were in stage T1Nx,0,1M1, 12 patients in stage T2Nx,0 M1, 8 patients in stage T3NxM1, 5 patients in stage T4NxM1. These 46 patients of T1 -T3 had their primary diseases removed, but the 5 T~ patients didn"t have their primary diseases removed. These 51 patients received oral sorafenib 400 mg Bid continual-ly and they had CT scan every two months to evaluate the progression. The dosage of sorafenib wasmodified according to efficacy and toxicity. Two patients changed the dosage to 200 mg Bid due to se-vere side effects. Sixteen patients increased the dosage to 600 mg Bid or 800 mg Bid. The response ofSorafenib and toxicities as well as their severity were recorded. The toxicity severity was graded ac-cording to National Cancer Institute Common Toxicity Criteria version 3.0. The efficacy was deter-mined by RECIST criteria. The efficacy and progression free survival (PFS) were recorded. The sta-tistics analysis was conducted between sorafenib's side effects and efficacy as well as their severity by multi-faetor Logistic regression. Results The rates of adverse events in the patients receiving oral sorafenib were hand-foot skin reaetion 68. 6% (35/51), diarrhea 39. 2% (20/51), rash 25. 5% (13/ 51), mucositis 23.5% (12/51), hypertension 17.6% (9/51), and myelosuppression 13. 7%(7/51). The response rate in the patients who had toxicity of grade 3-4 was 33.3%(12/36), and that in the patients who had slight toxicity was 12.0%(3/25). The rate of hand-foot skin reaction was higher than that of diarrhea, rash, mucositis, hypertension and bone marrow suppression (P<0.01). Sor-afenib's efficacy was eorrelated to rash and mueositis (P=0.048, 0.045 respectively). More grade 3 4 side effects occurred in the patients who would have better response to sorafenib (P=0.008). The median PFS was 15.0 months and PFS was not related to the toxicity and its severity. Conclusions It may help to predict the response for sorafenib's side effects and efficacy in the treatment of the patients with advaneed renal cell earcinoma.

Objective To analyze the effect and related factors of sorafenib in the treatment of metastatic renal cell carcinoma(MRCC), and identify the potential predictive factors of sorafenib re-sponse. Methods The data of 51 MRCC patients who received sorafenib therapy, with or without combination with interferon or chemotherapy were retrospectively reviewed. After two cycles of treat-ment, patients were evaluated for progression or response. Pearson Chi-square test and Logistic re-gression test were performed respectively as univariate and multivariate analyses of sorafenib response. Results The overall objective response rate was 29.4%(95% confidence interval 16.9% to 41.9%, with 1(2.0%) complete response and 14(27.4%) partial responses. Twenty-nine(56.9%) had stable disease, and 7 (13.7%) had progression disease (PD). Significant independent predictive factors asso-ciated with good response in multivariate analysis were lung metastasis only(P=0.021, HR=5.127). Conclusions Sorafenib is effective in MRCC patients. Lung metastasis only is predictive factor in mul-tivariate analysis for sorafenib response.

Objective To investigate the relationship between human leptin receptor(LEPR)gene G3057A polymorphism and type 2 diabetes complicated with non-alcoholic fatty liver disease(NAFLD).Methods 216 cases of newly diagnosed type 2 diabetes(104 cases complicated with NAFLD)and 108 cases of normal glucose tolerances(NGT)were recruited.Hemi-nested PCR-RFLP and PCR direct sequence analysis were conducted to detect the polymorphisms of LEPR G3057A polymorphism.The plasma leptin and insulin levels were measured by ELISA kit.Plasma lipid and glucose metabolic parameters were measured routinely.Liver ultrasound scanning Was carried out among all subjects.Results Type 2 diabetic patients complicated with NAFLD had higher plasma alanine aminotransferase(ALT),triglycerides(TG),low density lipaprotein cholesterol(LDL-C),leptin levels and lower plasma insulin levels than those cages without NAFLD and NGT.The variant frequency at nucleotide 3057 G to A transversion Was 76.0% in type 2 diabetic patients complicated with NAFLD,which Was also significant higher than those cases without NAFLD(62.1%)or NGT cases(53.2%)(x2=14.63,P＜0.01).Conclusions The polymorphism of LEPR gene 3057 probably contributes to the onset of NAFLD in type 2 diabetes by regulating lipid metabolism and affecting insulin sensitivity.
