BACKGROUND:Currently, there is stil no clear conclusion on the pros and cons of arthroscopic anterior cruciate ligament reconstruction with or without stump preservation residues as wel as the impact of reconstruction with stump preservation on proprioceptive sensation. OBJECTIVE:To compare the curative effect of arthroscopic anterior cruciate ligament reconstruction with or without stump preservation on the function and stability of the knee joint during a 1-year folow-up. METHODS: A retrospective analysis of 75 cases of arthroscopic anterior cruciate ligament reconstruction was done, including 37 cases of anterior cruciate ligament reconstruction without stump preservation and 38 cases of anterior cruciate ligament reconstruction with stump preservation. Autologous hamstring tendons were selected as implants. Evaluation of preoperative (6 months before operation) and postoperative (6 months and 1 year after operation) knee function and stability was implemented on the basis of Lysholm scores, IKDC Scores and KT2000. The comparative analysis was carried out as wel on repeated passive angle for proprioception testing. RESULTS AND CONCLUSION:Al of the patients were folowed up for 12 to 20 months. Range of motion of the knee joint was basicaly restored in the two groups 6 months after operation. The results showed the Lysholm scores, IKDC scores and KT-2000 scores at 6 months and 1 year after operation were significantly improved in the two groups as compared with the preoperative data (P < 0.05), and there was no statisticaly difference between the two groups. The proprioception difference between the healthy and affected sides was lower in the patients with stump preservation than those without stump preservation at 6 months and 1 year after operation (P< 0.05). There were two cases in each group whose bone tunnel of the tibia was found deviating from the ideal position through postoperative X-ray examination, but cyclopia was unseen. Anterior cruciate ligament reconstruction with stump preservation is beneficial to the recovery of postoperative proprioception without increasing of postoperative complications.

Objective To understand the empiric antimicrobial use in patients with pyelonephritis in a hospital,and pro-vide reference for clinical rational antimicrobial use.Methods Data of 620 patients with pyelonephritis admitted to the nephrology department of a hospital between January 2011 and September 2014 were collected,application of antimicrobial agents,coincidence between empiric antimicrobial use and antimicrobial susceptibility testing results in patients with different diseases and different ages were analyzed.Results Before antimicrobial susceptibility testing results were reported,620 pa-tients use 625 times of antimicrobial agents,5 of whom used two kinds of antimicrobial agents at the same time,8 varieties in 15 types of antimicrobial agents were involved,the most frequently used antimicrobial agents were third generation ceph-alosporins,cephamycins,and fluoroquinolones.The overall,partial,and non-coincidence rate between antimicrobial use and antimicrobial susceptibility testing results were 64.32%(n=402),8.32%(n=52),and 27.36%(n=171)respective-ly.The overall coincidence rate in patients with acute pyelonephritis was higher than those with chronic pyelonephritis (77.61% [n=357]vs 58.79%[n=97],P <0.05).The overall coincidence rate in patients <50 years old and ≥50 years old were 68.12%(156/229)and 75.25%(298/396)respectively,there was no significant different between two groups (χ2 =2.93,P =0.09).Conclusion The non-coincidence rate between empiric antimicrobial use and antimicrobial suscepti-bility testing results is high,measures needs to be taken to improve the empiric antimicrobials use.

OBJECTIVE To investigate the protective effect of Sika deer velvet antler protein (SVPr) against renal toxicity in mice and its mechanism.METHODS Forty ICR mice were randomly divided into 5 groups:normal control group (ig distilled water),model group (ig distilled water for 7 d,on the 7th day,ip cisplatin 25 mg·kg-1 to establish the model,afterwards ig distilled water for 3 d) and SVPr 5,10 and 20 mg· kg-1 groups (ig SVPr for 7 d,cisplatin 25 mg· kg-1 was provided 2 h after the last administration,then ig SVPr for 3 d).Testing kits were adopted for the measurement of renal indexes in mice,such as blood urea nitrogen (BUN) and serum creatinine (SCr);oxidative stress indictors of super oxide dismutase (SOD),catalase (CAT),glutathione (GSH) and malondialdehyde (MDA);inflammation indictor levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6).Caspase 3,Bax and Bcl-2 were detected via Western blotting,and renal pathological changes were observed by HE staining.RESULTS SVPr (5,10 and 20 mg·kg-1) significantly reduced the levels of SCr,BUN,MDA,TNF-α and IL-6,and the expressions of caspase 3 and Bax (P<0.05),but increased the activities of SOD,CAT and GSH,and the expression of Bcl-2 (P<0.05).The renal pathological changes were improved.CONCLUSION SVPr can reduce renal toxicity induced by cisplatin in mice,and the mechanism is probably related to inhibiting oxidative stress or inflammatory reaction and improving cell apoptosis.

Objective To investigate the feasibility and curative effect of botulinum toxin type A(BTX-A)point injection under the guidance of type-B ultrasonic on upper limb spasticity after stroke.Methods 18 cases were divided into two groups:9 cases for treatment group were treated with point injection BTX-A in 5 points with the guidance of type-B ultrasonic diagnosis,other 9 cases for control were only injected experientially.They were evaluated with the modified Ashworth scale(MAS)and the time taking effect were recorded.Results Compared with the control,the scores of MAS in the treatment group improved,and they came into effect more quickly(P<0.05).Conclusion The point injection of BTX-A under the guidance of type-B ultrasonic was practicable for and effective on upper limb spasticity after stroke.

Objective To evaluate the clinical effect and complications of total hip replacement (THR) in novel femoral neck fracture,old femoral neck fracture, aseptic necrosis of femoral head and coxa degenerative osteoarthropathy. To provide instructions to surgical indications and treatment effects analysis.Methods One hundrde and four patients were divided into 4 groups by disease type: novel femoral neck fracture group (n = 32 ), old femoral neck fracture group (n = 22) ,aseptic necrosis of femoral head group (n =34) and coxa degenerative osteoarthropathy group (n = 16). These patients were followed-up for 12 - 144 months after THR, their Harris standard score and complications data, before and after operation, were analyzed retrospectively. Results After operation, the Harris standard scores were 92. 6 ± 5.8,90. 1 ± 5. 2,86. 3 ± 4. 6,81.9 ±4. 1 in novel femoral neck fracture,old femoral neck fracture,aseptic necrosis of femoral head and coxa degenerative osteoarthropathy groups respectively, which were significantly higher than the scores before operation (25.6±1.8,36.7±2.6,52.9±4.3,42. 1 ±3.8,Ps <0.05). Conclusion THR has good effects in the four types of diseases. Short length of stay and high healing rate are marked characteristics of THR. More attention shoud be paid to the complications of THR.
