Objective To investigate the effect of malignant tumor on neuromuscular block of cisatracurium. Methods Sixty ASA Ⅰ or Ⅱ patients with head and neck neoplasms (15 cases with benign tumor, 45 with malignant tumor), aged 18-64 yr, were randomly divided into 4 groups ( n = 15 each): Ⅰ benign tumor group (group B,3 × ED95 ); Ⅱ -Ⅳ different dose cisatracurium group (group C1 (2 × ED95 ), C2 (3 × ED95 ) and C3 (4 ×ED95)). Neuromuscular block was assessed with accelerograph F (TOF-watch SX). Single stimulation of ulnar nerve was used. Anesthesia was induced with TCI of propofol (target plasma concentration 3 μg/ml) and remifentanil (target effect-site concentration 3 ng/ml). Tracheal intubation was facilitated with cisatracurium 0.15 mg/kg in group B, and with cisatracurium 0.10, 0.15 and 0.20 mg/kg in group C1, C2 and C3 respectively. The onset time, clinical duration, time for recovery of T/Tc to 75 % and recovery index were recorded. Results The clinical duration, time for recovery of T/Tc to 75 % and recovery index were significantly longer in group C2 than in group B (P ＜ 0.05). The onset time was significantly shorter, while the clinical duration and time for recovery of T/Tc to 75% were significantly longer in group C2 and C3 than in group C1 , and in group C3 than in group C2 ( P ＜0.05) .Conclusion The duration of action and recovery times of cisatracurium were prolonged in patients with malignant tumor.

OBJECTIVETo investigate the clinical effect of steroids on reducing postoperative edema in rhinoplasty.

METHODSCochrane, Medline data, Pubmed date, were searched and updated on October 2013. Randomized controlled trials(RCTS) studies were included to assess the efficacy of steroids on decreasing postoperative edema after rhinoplasty. The methodological quality of the included studies was evaluated, and date analyses were performed using the Cochrane Collaboration's software RevMan 5.2.

RESULTSA total of 4 RCTS involved 172 patients with rhinoplasty, including 87 patients in the experimental group( steroid) and 85 paitents in control group (placebo). Meta analysis results showed the edema in experimental group was significantly less than that in the control group on postoperative day 1 and 3 (P < 0.01), while the difference was not significant on postoperative day 7 (P = 0.19).

CONCLUSIONSPerioperative application of steroid in rhinoplasty can significantly reduce periorbital edema in the first postoperative day. The edema can completely be relieved after application of steroid for 3 days. It is a safe and effective way to reduce the postoperative edema.

Objective To explore the methods for endoscopy nasal microsurgery and multiple techniques in treatment of nasopharyngeal angiofibromas. Methods CT, MRI and digial substraction angiography (DSA) and endoscopic examination had been used. ALL 12 patients accepted preoperative feeding artery embolum, hypotention anesthesia and injected adrenaline-lidocaine. Microelectrotomy-electrocoagulation had been used to remove tumor. Results All patients were treated by endoscopic nasal surgery. No complications had occurred. No recurrence were found in follow-up period. Conclusion The important factors to reduce amount of introperative bleeding are to select proper operative patients and use multiple techniques. Endoscopy nasal surgery has dominance in reducing complications, wound, tumor recurrence, operative time and nasal function.

Objective To explore the clinical efficacy of early surgery combined with electron linac therapy on keloid.Methods The keloid patients with stable phase were selected;complete resection of keloid and relaxation suture were performed;after the surgery within 24 hours 6 MeV with Varian 2300CD radiotherapy was given,each measuring 4 Gy,total dose of 20 Gy.Results 860 cases of patients were colected for a period of 3 months to 36 months of regular follow-up,which recovered in 802 cases (cure rate was 93.26％),effective results were observed in 41 cases (effective rate of 4.77％),including 17 cases of recurrence (recurrence rate 1.98％),the total efficiency (cure plus effective) was 98.02％.Conclusions More accurately immediate radiotherapy after surgery can effectively reduce the recurrence rate,which is a safe and effective method in the treatment of keloids.

OBJECTIVETo evaluate in vitro effect of abnormal savda munziq (ASMq) on the proliferation and apoptosis of human hypertrophic scar fibroblasts (HSFs).

METHODSHSFs were divided into six groups to receive different treatments as group A (blank control group), group B-E (ASMq in different concentration), and group F(5-Fu). Each group contains six specimens. The HSFs were cultured in vitro. After culture for 48 hours, the CCK8 test and flow cytometry methods were used to detect the proliferation, cell cycle and apoptosis.

RESULTSThe proliferation of HSFs in the B, C, D and E groups was inhibited at G2/M period, while it was inhibited at G0/S period in group F (P < 0.05). The inhibition effect of ASMq (0.1-1.0 mg/ml) on the fibroblasts enhanced in a concentration-dependent manner. Flow cytometry analysis with annexin V-FITC and PI staining confirmed the apoptotic. When HSFs were exposed to ASMq at 1.0 mg/ml (group E) for 48 h, the percentage of apoptotic cells increased to (43.7 +/- 2.58)%, which was significantly higher than that of blank control group (2.2 +/- 0.59)%. The induced apoptosis effect was also increased in a concentration-dependent manner.

CONCLUSIONASMq has a inhibitory effect on the proliferation and an enhancement effect on the apoptosis of fibroblast. ASMq could be used as an effective drug for treatment of hypertrophic scar.

Objective To improve the level of early detection and treatment of pyonephrosis. Methods This study included 41 cases(17 men and 24 women;mean age,49 years)of pyonephrosis.A variety of examinations,including urinary analysis,blood analysis,kidney nuclear medicine scan,ultrasonog- raphy,intravenous urography(IVU),and CT were used for the early diagnosis of pyonephrosis.Pereutaneous nephrostomy(PCN)drainage was done for the interim management of pyonephrosis,then phase 2 operation was performed in 28 cases.The double-J tube was placed in ureter by ureteroscope for drainage,and then phase 2 operation was done in 2 cases.Emergency operation was done in 10 cases.The remaining 1 case un- derwent ESWL after anti-infective therapy.Results Definite diagnosis of pyonephrosis before operation was made by invasive examinations in 31 cases(75.6%),and by percutaneous drainage in 4 cases;the other 6 cases were detected during operation.Only 6 cases(14.6%)underwent nephrectomy;the other 35 cases (85.4%)underwent kidney-sparing operation.Follow-up of 3 months to 9 years was available in 37 cases. No nephrectomy was needed in 33 cases with spared kidney.Serum creatinine was normal in the 4 cases un- dergoing nephrectomy.Conclusions The key to the treatment of pyonephrosis by kidney-sparing surgery is early diagnosis,timely drainage and relief of obstruction.Ultrasonography plays an important role in the early diagnosis of pyonephrosis,and CT has a high sensibility in the diagnosis.Pereutaneons nephrolithotomy (PCNL)secondary to drainage through pereutaneous nephrostomy was beneficial to the patients with kidney stones or upper ureter stones.

BACKGROUNDLaparoendoscopic single-site surgery (LESS) approaches have been reported for treating various kidney and pelvic procedures, and are feasible and effective in selected patients. In this study, we aimed to present the initial experience and evaluate the efficacy of laparoscopic radical prostatectomy performed through a single incision using a multichannel port.

METHODSBetween July 2010 and April 2011, six patients diagnosed with early stage prostate cancer underwent LESS radical prostatectomy (RP) in our institute. A multichannel port was inserted transperitoneally through a 2-cm umbilical incision. Specially articulating and flexible laparoscopic were used. Some technical tricks and points were applied during the operation to overcome the drawbacks and reduce the difficulties of this approach. Two continuous urethrovesical sutures in both sides were performed to complete both lateral aspects of anastomosis. The two ends of the suture threads were fixed by double Lapro-Clips, instead of the difficult knot-tying.

RESULTSTotal operative time was (265 ± 43) minutes. Mean blood loss was (230 ± 65) ml. All cases were completed successfully, without conversion to open surgery or adding additional abdomen ports. No patient required a blood transfusion and no intraoperative complications occurred. The Foley catheter was removed at the 14th day (range 12th - 16th) after surgery. At the 12th week of follow-up, all patients had an undetectable prostate-specific antigen level. Two patients used 2 or 1 pad for continence daily; other patients had achieved good continence.

CONCLUSIONIn selected cases, LESS-RP is feasible and effective; these technic points and the flexible-articulating instruments are helpful to reduce the operation difficulties.

Objective To investigate the potential role of disc repositioning and condyle restoration in the treatment of type Ⅲ traumatogenic temporomandibular joint (TMJ) ankylosis. Methods Eight patients including four females and four males at age range of 7-22 years (mean 13.6 years) were enrolled in this study. The patients suffered from traumatogenic TMJ ankylosis for 1-12 years. The preoperative interincisal opening distances ranged from 2 mm to 10 mm. During surgery, the traumatogenic callus of the lateral condyle process was removed, the condyle process was formed, and then the dislocated disc was sutured to the articular capsule or soft tissues around. Results All patients were followed up for 6-38 months and the last follow-up examination showed that the average interincisal opening distance was 30 mm. No recurrence or TMJ symptoms were found during the period of follow-up. Conclusions Disc repositioning and condyle restoration has the advantages of simple procedures, minor trauma and little recurrence and proves to be a feasible and effective method for the treatment of type Ⅲ traumatogenic TMJ ankylosis.

OBJECTIVETo analyze the causes of chest or/and abdomen colic with in 1 week after prostatectomy and transurethral resection of the prostate (TURP).

METHODSRetrospective studies were made on 120 cases of benign prostatic hyperplasia (BPH) with postoperative colic in the chest or/and abdomen from October 2001 to October 2002, 35 (Group A) treated by prostatectomy and the other 85 (Group B) by TURP.

RESULTSIn sequence of frequency, the causes of the postoperative chest or/and abdomen colic were bladder spasm, catheter block, acute gastroenteritis, angina and acute myocardial infarction.

CONCLUSIONThe causes of chest or/and abdomen colic after prostatectomy are multiple. If the causes are timely established and corresponding measures immediately taken, its complications can be minimized.
