Objective: To observe the effects of pentazocine on emergence agitation.Methods: Totally 60 patients with scheduled upper limb operation with general anesthesia were randomly divided into two groups (n =30).Group Ⅰ was given pentazocine 0.25 mg·kg-1 (diluted to 10ml) and group Ⅱ was treated with 0.9% sodium chloride (10 ml) and both were with slow intravenous injection above 3 min before the surgical stitching.BP and HR were recorded and compared before the induction (T 0), before the extubation (T 1) ,at the extubation (T 2), and 5, 10 and in 15 minutes after the extubation (T 3 , T 4 and T 5).The time of recovery, time of extubation and agitation scores in 15 min after the extubation were recorded and compared, and nausea and vomiting were observed as well in both groups.Results: Compared with those in group Ⅰ, HR and BP in group Ⅱ were significantly higher (P＜0.05) at T 3 , T 4 and T 5.There were no significant differences in the breathing recovery time and awakening time between the groups (P＞0.05).The restlessness score in group Ⅰ was significantly lower than that in groupⅡ (P＜0.05).The incidence and degree of postoperative nausea and vomiting in groupⅠ were significantly higher than those in group Ⅱ (P＜0.05).Conclusion: Pentazocine (0.25 mg·kg-1) given before stitching can maintain stable circulation, reduce emergence agitation and protect the safety of patients.

To investigate the changes of immunological function of LAK,NK cell activity and T lymphoctyes subsets before and after operation in patients with hepatic cancer.The activity of Lymphokine-activated Killer Cell (LAK|,Natural Killer Cell(NK) and T lymphocytes subsets were detected in 31 patients with hepatic cancer of preoperation and postoperation,so did the 30 normal volunteers(as control group).The results showed that the activities of LAK,NK cell and T lymphocytes subsets of CD3,CD4 and the ratio of CD4/CD8 in patients with hepatic cancer were lower than that in normal control group(P

Nomegestrol acetate, 19-norprogesterone de ri vatives, has been used for oral contraception. Recently, studies showed that nom egestrol was a selective estrogen enzyme modulator (SEEM). Nomegestrol is capabl e of inhibiting estrone sulfatase and 17-beta-hydroxysteroid dehydrogenase (17 beta-HSD) and increasing the activity of sulfotransferase,which will provide a new option in the treatment of breast cancer. In addition, nomegestrol has stro ng reversal effects on multidrug resistance in breast cancer cells. In vitro, nomegestrol also exhibits as an inhibitor on endometrial proliferation in uter us. These advances will be introduced in the present review.

Objective To analyze the clinical and immunological manifestations of antiphospholipid syndrome(APS)in a cohort of 100 patients.Methods The clinical and serologic features of APS(Sapporo preliminary criteria)in 100 patients were analyzed retrospectively.Results The cohort consisted of 79 female patients and 21 male patients witb a mean age of 36?13 years at diagnosis.Primary APS was presented in 37% of patients;APS was secondary to systemic lupus erythematosus(SLE)in 46%,lupus-like syndrome in 14%. Eighty percent of the patients had thrombosis,43(54%)patients had venous thrombosis,18(22%)had arterial thrombosis,15(19%)had both arterial and venous thrombosis.4(5%)had thrombosis of microcirculation. Forty-two(52%)patients presented thrombosis at a single site,26(32%)at two sites,12(15%)at three or more sites.Forty-five(56%)patients experienced one thrombotic episode,20(25%)patients had only one re- currence,and 15(19%)had more thrombosis.The most common manifestations of thrombosis were deep vein thrombosis(36%),pulmonary embolism(30%)and stroke(26%),with heart,kidney,gastrointestinal tract and other organs involvements.Thirty-four(51%)female patients had spontaneous fetal losses including intrauter- ine fetus death and recurrent spontaneous abortion.Seventy-one(71%)patients developed thromboeytopenia. The presence of antieardiolipin antibody(ACL)was detected in 84 patients(84%).Among 90 patients with APS,alone ACL was detected in 38 patients(42%),both ACL and lupus anticoagulant(LA)were detected in 36(40%),LA alone in 16(18%).Patients with APS associated with SLE or lupus-like syndrome had higher frequency of arthritis,leukopenia,antinuclear antibodies(ANA)and low complement levels.Female patients had a higher frequency of leukopenia,ANA and ACL.Male patients had a higher prevalence of deep venous thrombosis in the lower limbs and LA.Conclusion APS is an autoimmune disorder characterized by recurrent arterial and venous thrombosis,fetal loss,or thrombocytopenia with the presence of ACL and/or LA.In APS secondary to with SLE,the patient's sex can modify the disease expression and define specific subsets of APS.

Objective To compare the reproducibility and reliability of facial soft tissue landmarks using a direct and an indirect placement methods in facial three-dimensional (3D) soft tissue assessment.Methods 3D coordinates of 37 soft tissue landmarks were obtained respectively in 35 normal healthy volunteers from 3D optical capture system and Materialise's interactive medical image control system (Mimics).Landmarks were affixed on the cutaneous surface (direct method) and marked on the 3D reconstructed craniofacial model (indirect method).Intra-class correlation coefficients (ICCs) and paired t-tests were used to compare the reliability and reproducibility of facial landmarks between two placement methods.Results For the direct placement method,86.5 ％ landmarks had an ICC higher than 0.75.For the indirect placement method,75.7％ landmarks had an ICC higher than 0.75.The inter-observer variability using the direct placement method was (1.259±0.566) mm,which was significantly smaller (P＜0.05) than (1.420±0.638) mm obtained by the indirect placement method.Conclusions Compared with indirect method,direct method has higher reliability and reproducibility in evaluating facial soft tissue.

OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.

METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.

RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).

CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.

AIM: To explore the effect of L-arginine (L-Arg) on the arrhythmia induced by ischemia/reperfusion (IR) of the right coronary artery in rabbits. METHODS: 48 healthy adult rabbits were divided into 4 groups (n=12 of each) randomly: IRa group (120 min reperfusion after 30 min ischemia), IRb group (120 min reperfusion after 120 min ischemia), IRa+L-Arg group and IRb+L-Arg group. I/R model was established by occluding and loosening the root of the right coronary artery in rabbits. The changes of ECG and arrhythmia were recorded and graded. RESULTS: ① The longer time of IR was, the higher the score of the arrhythmia was found. The incidence of atrial-ventricular block (AVB), sinus-atrial block (SAB), even sinus arrest were detected and aggravated gradually. ② The incidence of AVB was decreased and from Ⅲ?→Ⅱ?→Ⅰ? markedly, some of sinus and atrial arrhythmia were transformed into sinus rhythm gradually, and all of the arrhythmia scores in IRa group were decreased significantly as compared with the same time phases of IRb group (P
