[Objective]To investigate the advantages, risks and kye points of minimally invasive total knee arthroplasty with subvastus approach. [Method] From April 2005 to December 2006, 204 primary total knee arthroplasties were performed, among them 146 cases with convention incision (CI), 58 cases with minimally invasive subvastus approach(MIS). All knees were implanted with the same prosthesis (NEXGEN-LPS, Zimmer).The anesthesia time,operation time, hospitalization time were recorded.The first walking time, walking distance, active knee range of motion, preoperative and postoperative HSS Score and the complications were compared. [Result] Totally 204 cases were followed up and the mean follow-up time was 22 months (range, 13-36 months). The difference of anesthesia time, length of incision, operation time, hospitalization time, walking time had significance between the CI and MIS groups ( u test, P0.05). The difference of active range of motion in 24 hours, 1 week, 2 weeks postoperation had significance between the two groups ( u test, P0.05).The difference of HSS score in 24 hours, 1 week, 2 weeks after operation had significance between the two groups ( u test, P0.05). [Conclusion] The minimally invasive total knee arthroplasty with subvastus approach reduces the quadriceps injury, offers early active knee motion and quickly recovery of knee function. However there is no significant difference in long-term walking distance, range of motion and HSS score.

[Objective]To investigate the mechanism and pathologic changes of anterior cruciate ligament impingement syndrome as well as its arthroscopic diagnosis and treatment.[Method]From January 2005 to June 2007,28 patients with a history of anterior cruciate ligament impingement were diagnozed and treated arthroscopically.The patients' clinical findings were mainly anterior patellar pain and limited knee joint.The reasons of anterior cruciate ligament impingement syndrome were indentified by routine arthroscopic examination:straitness of intercondylar notch or osteophytes formation in 19 cases,old avulsion fracture in the tibial intercondylar in 4 cases,anterior cruciate ligament cyst in 3 cases,incorrect tibial tunnel placement on reconstructed anterior cruciated ligament in 2 cases.Different surgical procedures were carried out according to the results of the examination:joint debridement and intercondyle's plasty;intercondyle's plasty and osteophytes resection;joint debridement and ACL cysts resection;ACL tibial eminence insertion reconstruction were performed.[Result]Twenty-eight cases were followed for an average of 15 monthes(6-34 monthes).The rate of good to excellent was 82.1%,recurrence was observed in 1 case.[Conclusion]The gradual constriction of the knee is mainly caused by the anterior cruciate ligament impingement syndrome.Arthroscopy is very valuable in diagnosis and treatment of anterior cruciate ligment impingement syndrome.It can also acquire whole assessment of the joint injuries and makes out reasonable treatment program to normal knee joint function.

Objective To investigate the efficacy and safety of adjusting the doses of diuretics of different time in the treat-ment of advanced schistosomiasis ascites. Methods A total of 80 advanced schistosomiasis patients with ascites were randomly divided into an observation group and a control group(40 cases each). The patients in the observation group received spironolac-tone and furosemide,and the first doses were 100 mg/d and 40 mg/d,respectively. If the efficacy was poor,according to the first doses of the standard increments once every four days,the doses gradually increased to the maximum doses of spironolactone 400 mg/d and furosemide 160 mg/d,respectively. The patients in the control group received spironolactone and furosemide,and the first doses were the same as those of the observation group. If the efficacy was poor,according to the first doses of the standard in-crements once every seven days,the doses gradually increased to the maximum doses as those of the observation group. Other con-ventional treatments were the same in both groups. Results In both groups,the reductions of the total amount of the weight were (5.62±1.28)kg and(5.42±1.37)kg respectively;the time of efficacy beginning was(3.84±2.36)days and(4.65±2.86)days re-spectively;the average daily amounts of weight loss were(0.41 ± 0.16)kg and(0.35 ± 0.11)kg respectively;the efficient rates were 95%and 92.5%respectively;and there were no significant differences between the two group(all P>0.05). However,the time of reduction from moderate ascites to mild ascites was(10.70±3.01)days(6-20 days)in the observation group and the time was(14.75±5.62)days(7-30 days)in the control group(u=3.876,P<0.01). Conclusion The therapy of diuretic doses ad-justed by a four-day cycle is more useful for advanced schistosomiasis patients with ascites.

Objective To explore the curative effect of traditional Chinese herbal packet combined with ST 36 injection therapy on gastrointestinal dysfunction in severe patients. Methods Sixty severe patients with gastrointestinal dysfunction were randomly divided into the control group and treatment group with random digital number, 30 cases in each group. The control group received conventional care and besides conventional care , the treatment group was treated with traditional Chinese herbal packet combined with ST 36 injection. The two groups were compared 7 days after treatment in terms of scores by (acute physiology and chronic health evaluationⅡ, APACHEⅡ) and improvement of gastrointestinal dysfunction. Result After treatment, the APACHE II score and improvement of gastrointestinal dysfunction of the treatment group were significantly higher and better than those of the control group (P<0.05). Conclusion The traditional Chinese herbal packet combined with ST 36 injection can promote the recovery of gastrointestinal dysfunctional in severe patients.

Objective To investigate the imaging appearances of non-ossifying fibromas in healing stage and its clinical value.Methods The imaging features of non-ossifying fibroma in healing stage in 10 cases followed-up clinically(2 cases of them were verified by pathology after operation) were analyzed. All of the cases were examined by radiography,4 cases were examined by CT, 1 case underwent MRI. Results All of the cases were located in long bone of lower extremity. 8 cases were in tibia,2 cases were in femur. 5 cases were shown as homogeneous sclerosis,lucent areas were presented in sclerotic foci in 5 cases. 5 cases were unchangeable after followed-up 1 to 4 years .Conclusion The non-ossifying fibroma is being sclerotic stabilized foci after puberty , no operation is necessary for the healed form non-ossifying fibroma.

OBJECTIVE: To discuss the potential problems caused by the exfoliation of the tunic albuginea after the low-temperature plasma operation. METHOD: To observe the occurrence of the tunic albuginea, exfolliating time, wound healing and its complications by following the patients received the low-temperature plasma operation from November in 2012 through June in 2013 (including 116 cases of tonsillectomy, 98 cases of adenoidectomy, 255 cases of the ablation of the inferior turbinate,8 cases of the ablation of the cyst of epiglottis, and 4 cases of the ablation of the tumor of larynx) together with reviewing the relevant literatures. RESULT: The tunic albuginea exfolliated about two weeks after tonsillectomy, bleeding was found in 3 cases, one of which was related with inappropriate eating; the exfoliation about two or three weeks after adenoidectomy, without the occurrence of the narrow nostril and pharyngeal cavity adhesion; about four weeks after the ablation of the cyst of epiglottis, bleeding was found in 1 case; about three or four weeks after the ablation of the inferior turbinate, massive bleeding was found in one case after two months; and the ablation of the tumor of larynx, one with severe atypical hyperplasia and carcinoma in situ, the theunic albuginea did not completely exfoliate four moths after the surgery and new creatures could be found, the wound looked smooth and healed well nine moths after the surgery. The full exfoliation occur four months after the surgery for one with the neurilemmoma in the left laryngeal ventricle and the new creatures could also be found. It exfoliated eighth days after the surgry for one patient with left subglottic epitheliaoid heman-gio endothelioma and it did not recur even six months after the surgery. Another one with the cyst of the left plica aryepiglottica failed to be followed. The first three patients did not suffer from such complications as bleeding, endogenous in trachea, etc. CONCLUSION Low-temperature plasma surgery has obvious advantages, but the potential problems caused by the surgery need to be taken in accounted, especially the exfoliating time of the tunia albuginea is different after the ablation of the tumor of larynx, which is inconsistent with what the literatures reported, it could partially due to the action time of low-temperature plasma surgery with surrounding tissues.

Objective To investigate the effect of electroacupuncture on the expression ofα-amino-3-hydroxyl-5-methyl-4-isoxazole propionate (AMPA) receptor associated protein glutamate receptor interacting protein (GRIP)1 and GRIP2 in hippocampal neurons of rats with Alzheimer's disease (AD) model induced by Aβ25-35. Methods 40 Male Sprague-Dawley rats were randomly divided into normal group, sham operation group, model group and electroacupuncture group with 10 rats in each group. The AD rat model was prepared by injecting Aβ25-35 in the hippocampus CA1 of rats, while the sham operation group was injected with equal amount of normal saline at the same loca-tion. On the second day after successful modeling, the electroacupuncture group received electroacupuncture at Baihui (DU20) and bilateral Shenshu (BL23) acupoints, once a day, 6 times a week for 2 weeks. The expression of GRIP1 and GRIP2 were detected with immunohisto-chemistry. Results There was no difference in the expression of GRIP2 and GRIP1 proteins in hippocampus between the normal group and sham operation group (t<1.7438, P>0.05), but was lower in the model group and the electroacupuncture group than in the sham operation group (t>9.5928, P<0.001), and was higher in the electroacupuncture group than in the model group (t>9.5326, P<0.05). Conclusion Elec-troacupuncture may increase the number of AMPA receptors on the postsynaptic membrane by increasing GRIP1 and GRIP2.

Objective To investigate the clinical application of iodine-enhanced image of dual-source computed tomography (DSCT) in distinguishing benign and malignant thyroid nodules.Methods Thirty patients with thyroid nodules underwent DSCT imaging with dual-source computed tomography.All thyroid nodules were confirmed by operation or biopsy.Iodine concentration in the thyroid nodule and normal thyroid tissue were calculated and not enhanced.A receiver operator characteristic curve in SPSS software was utilized to select critical value of optimum sensitivity and specificity.The data were retrospectively analyzed.Results There were 30 patients with 40 thyroid nodules (17 malignant nodules,23 benign nodules).The range of iodine concentration in malignant nodules was -2.4-0.9 mg/ml(median-0.5 mg/ml),and that in normal thyroid tissue was-0.9-2.2 mg/ml (median 0.7 mg/ml).The range of iodine concentration in benign nodules was 1.5-4.4 mg/ml(median 2.4 mg/ml),and that in normal thyroid tissue was 1.5-4.3 mg/ml (median 2.6 mg/ml).Among them,the iodine concentration in the solid part of benign nodules was significantly higher than that in malignant nodules,the difference was statistically significant(Z=-3.23,P=0.21).When critical value was 0.15 mg/ml,sensitivity was 82.40％,specificity was 81.00％.Conclusion Iodine-enhanced images with DSCT in non-enhanced weighted images may be an implement tool for differential diagnosis of benign and malignant nodules of the thyroid gland.
