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 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 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.
