Objective To investigate the characteristics,the incidence, relative factors of antibiotic associated diarrhea (AAD),and prevent and control it. Methods Retrospective analysis was performed in 78 patients with AAD. Results Prevalence ratio of AAD was 9.3%, the risk of AAD related to the kinds of using mix antibiotics and period of treatment, using many meddle measures for medical and age.The antibiotics causing AAD were extending penicillin or third cephalosporins, penicillin, carbapenemases, second cephalosporins.Conclusions Rational use of antibiotic,control use of antibiotic and reduce the state of consciousness are the key measures to prevent and control the AAD.

Objective: To compare cumulative dose technique with single dose technique for determining dose-re sponse relationship of rocuronium during balanced anesthesia. Method: Thirty-four ASA grade Ⅰ-Ⅱ patients, aged 23- 65 years, undergoing elective surgery,were randomly allocated to single dose group(n=24) or cumulative dose group (n=10). Single dose group was further divided into 4 subgroups receiving 150,200,250 or 300?g/kg of rocuronium re spectively. In cumulative dose group, the initial dose of 150 or 200 ?g/kg rocuronium was followed by a second dose de termined individually to produce about 90% neuromuscular block. The ulnar nerve was stimulated at the wrist to mea sure the accelography of thumb adduction. The relationship between probit-transformed depression of first twitch height of TOF and the logarithm dose of rocuronium was analysed using linear regression. Result: ED_50 and ED_95 of rocuronium were 193.6?69.1 and 367.2?72. 7?g/kg respectively in single dose group, and 213.0?55.1 and 418.5? 61.7?g/kg respectively in cumulative dose group. No statistically significant differences were found in the slope,inter cept,ED_50 and ED_95 values between two groups. Conclusion: The two-dose cumulative technique can be used as effec tively as traditional single dose technique in determining the dose-response relationship of rocuronium.

Objective To observe the effect of volume resuscitation on the early grafted kidney function in opration.Methods 909 cases were divided into five groups according to the volume resuscitation in opration:group A:

0.05). The onset time of 0.2mg/kg and 0.4mg/kg cisatracurium was significantly shorter than that of 0.1mg/kg cisatracurium and 0.5mg/kg atracurium (P

Objective To analyze clinical outcome of anterior atlantoaxial transarticular screw fixation in treatment of atlantoaxial instability.Methods Thirty-two patients with atlantoaxial instability treated between March 2004 and June 2009 were enrolled in the study.The patients consisted of 21 males and 11 females,at age of 22-64 years (mean 49 years).Atlantoaxial instability was attributed to old odontoid fracture in 10 patients,free odontoid malformation in 16,transverse ligament rupture in two,and rheumatoid arthritis in four.Anterior atlantoaxial transarticular screw fixation under monitoring of cortical somatosensory evoked potential (CSEP) was performed for all patients.Operation time,intraoperative blood loss,and complications were recorded.Japanese Orthopedic Association (JOA) scoring system was used to evaluate neurologic function preoperatively and at one year postoperatively.Results Operation lasted for average 98 minutes and intraoperative blood loss averaged 110 ml.Injuries on esophagus,nerve and vertebral arteries as well as leakage of cerebrospinal fluid were not observed in operation.All patients received a follow-up of 12-31 months.JOA score was increased from preoperative 9.8 points to 15.8 points at one year postoperatively,with improvement rate of 83％.Bone fusion and satisfactory internal fgxation were achieved in all patients.Hypoglossal nerve injury symptom was found in two patients postoperatively and was recovered two months later.Conclusion Anterior atlantoaxial transarticular screw fixation is an effective treatment for atlantoaxial instability.

Objective To summarize experience to prevent the main postoperative complications after hypospadias repairs. Method The clinical data of 189 cases of hypospadias repairs was from May 2005 to August 2010,retrospectively analyzed. Results One hundred and seventy-four cases were surgically cured by single-stage operation. All cases had been followed up for 4-36 (18.5 ± 5.5) months, the cases who had become adults were normal penile development and erectile function. Postoperative complications occurred in 15 cases,9 cases of them were urethral fistulas,6 cases were urethral strictures,all were cured or improved after symptomatic treatments. Conclusions Some methods are necessary to raise single-stage urethroplasty success rate and decrease the incidence of fistulas and strictures, such as preoperative antibiotic prophylaxis,appropriate procedure,intraoperative suprapublic urinary diversion,the good blood supply of the flap, modified enswathement, postoperative manage and nursing.

Objective To study the effects of cripto on migration, invasion, and liver metastasis of colorectal cancer cell. Methods After human colorectal cancer cell line SW480 was transfected by cripto small interfering RNA (siRNA), the mRNA and protein level were determined by Real-time RT-PCR and Western blot, respectively. The migration and invasion ability were evaluated by wound-healing assay and boyden chamber model, respectively. Thirty nude mice model of liver metastasis from colorectal cancer was established by splenectomy. Results The siRNA could down-regulate the level of mRNA and protein of cripto in a dose- and time-dependent manner. Suppression of cripto expression could inhibit migration and invasion ability of human colorectal cancer cell in vitro. The metastastic rate and tumor nodules were lower in transfection with cripto siRNA than in two control groups in vivo. Conclusions Cripto gene might play an important role in regulation of liver metastasis from colorectal carcinoma cell, and suppression of cripto gene by siRNA can inhibit liver metastasis of colorectal cancer.

Objective To discuss the clinical effects of internal fixation with pubic nails and sacroiliac screws aided by 3D navigation for pelvic fractures of Tile type B2 or B3. Methods A total of 27 patients with pelvic fracture of Tile type B2 or B3 received operative treatment in our hospital from De-cember 2013 to December 2016. They were 15 men and 12 women, aged from 20 to 68 years ( average, 39. 2 years ) . According to the Tile classification, 12 cases were type B2. 1, 8 type B2. 2, and 7 type B3. Of them, 20 were unilateral pubic rami fractures and 7 bilateral pubic rami fractures; there were 3 dislocations of the sacroiliac joint, 17 fractures of the sacral Denis regionⅠ, and 7 fractures of the sacral Denis regionⅡ. All the 27 cases were treated by internal fixation with retrograde pubic nails and sacroiliac screws aided by 3D navi-gation. Quality of fracture reduction, functional recovery of the pelvis and postoperative complications were recorded to evaluate the clinical effects. Results Totally 26 out of the 27 patients were followed up for 6 to 18 months ( average, 11. 4 months ) , with one lost to the follow-up. According to the Matta scoring, the pelvic reduction was evaluated as excellent in 20, as good in 4 and as fair in 2 cases, yielding an excellent and good rate of 92. 3％. All the fractures united after 12 to 20 weeks ( average, 13. 8 weeks ) . According to the Majeed scoring at the final follow-ups, the pelvic function was evaluated as excellent in 20, as good in 3 and as fair in 3 cases, giving an excellent and good rate of 88. 5％. Screw loosening happened in one patient who had ambulated too early. No permanent pain, wound infection, neurovascular injury, heterotopic ossification or thrombosis occurred. Conclusion For the treatment of pelvic fractures of Tile type B2 or B3, internal fixation with pubic nails and sacroiliac screws aided by 3D navigation can lead to satisfactory short-term outcomes due to advantages of limited operative invasion, short operation time and limited intraoperative blood loss.

Objective To study the effect of hypoxial endothelia cell conditional medium(HECCM)on the proliferation of pulmonary arterial muscle cell(PASMC).Methods MTT assay was used to test the proliferation,immuno-cytochemistry was used to identify the expression of ?-SM-actin.Results(1)HECCM could promote the proliferation of PASMC,down-regulate their expression of ?-SM-actin.(2)DDPH could up-regulate the expression of ?-SM-actin in PASMC which was time-dependant.Conclusions DDPH could reverse the phenotype transformation of PASMC exposed to HECCM,the action was time-dependant.After some time DDPH could reversly transform PASMC to the normal contractile phenotype.
