Objective To compare the effects oflightwand(LW) and direct laryngoscope(DL) in elderly patients undergoing surgery on hemodynamics and stress responses.Methods Forty elderly patients with ASA grade Ⅰ-Ⅱ grade who selective surgery were divided into LW group and DL group by random digits table method,each group with 20 cases.Systolic blood pressure (SBP),diastolic blood pressure (DBP),heart rate(HR) were recorded respectively before intubation,30 seconds and 5 minutes after intubation.Extracted patients with peripheral arterial 3 ml at the same time,measured by radioimmunoassay epinephrine and norepinephrine levels.Results The SBP,DBP,HR,epinephrine,norepinephrine 30 seconds after intubation in LW group were significantly lower than those in DL group [(140.50 ± 21.91) mm Hg(1 mm Hg =0.133 kPa) vs.(167.95 ± 17.85) mm Hg,(67.80 ± 6.76) mm Hg vs.(84.15 ±9.89) mm Hg,(85.10 ± 11.76) times/min vs.(96.30 ± 13.72) times/min,(49.47 ± 8.09) ng/L vs.(61.25 ± 9.43) ng/L,(171.27 ± 17.11) ng/L vs.(187.40 ± 16.13) ng/L,P ＜ 0.01].The SBP,epinephrine,norepinephrine 5 minutes after intubation in LW group were significantly lower than those in DL group [(120.75 ± 17.12) mm Hg vs.(136.65 ± 15.43) mm Hg,(39.80 ±7.38) ng/L vs.(47.63 ±8.48) ng/L,(155.93 ± 17.11) ng/L vs.(172.76 ± 13.45) ng/L,P ＜ 0.01].Conclusion Both LW and DL can be well done in elderly patients intubation,but LW can reduce stress responses during the intubation.

AIM:To analyze the cause of hip prosthesis dislocation,so as to prevent the dislocation following total hip arthroplasty(THA).METHODS:Between January 2002 and June 2007,a total of 348 cases(406 hips) received THA in the Department of Orthopaedics,the Second Affiliated Hospital of Fujian Medical University,and 15 patients(15 hips) occurred dislocation(3.7%),including 6 males and 9 females.Their age ranged 35-76 years,with a mean of 58 years.Primary affections consisted of femoral neck fracture in 3 cases(one with dislocation rebuilding after THA),femoral necrosis in 5 cases,hip arthodysplasia in 5 cases,and osteoarthritis in 2 cases.THA was carried out through lateral approach in 8 patients,and posterior lateral approach in 7 patients.The first dislocation occurred in 2 patients within 2 weeks,3 patients during 2-4 weeks,6 patients during 4-6 weeks,3 patients during 6-12 weeks,and 1 patient 12 weeks later.The movement of dislocation occurrence includes moving the patients in 2,turning over in 2,turning around in 4,trying to stand from sitting in 3,sock wearing in 3,and picking up in 2.It was revealed in the clinical analysis and operational incision that anterior dislocation was found in 6 cases,while posterior dislocation in 9 cases;proper placement of prosthesis in 5 cases,while incorrect placement in 10 cases.Close reduction was conducted in short time after dislocation,achieving success in 11 cases.There were 4 cases treated with open reduction after failure of close reduction,and hip joints were restricted.Seven patients were found dislocation again.And four patients prolonged external fixation and 3 patients were performed revision.RESULTS:The follow-up period ranged from 10 to 60 months.Eight cases succeeded the first reduction,with good joint stability and without relapse.Redislocation occurred in 4 cases,and was cured by prolonging fixation.No cases following revision were found dislocation.The average score was(85?5) according to Harris scoring system.There was no biocompatibility between the materials and the host.CONCLUSION:We should emphasize prevention of dislocation in the early THA and enough fixation time after reduction.

Colorectal cancer is one of the common malignancies of the digestive tract, and endoscopic submucosal dissection (ESD) has been widely used in the treatment of early colorectal neoplasms. The risk factors of non-curative resection in ESD for early colorectal neoplasms have been confirmed in many studies. This article reviewed the advances in study on risk factors of non-curative resection in ESD for early colorectal neoplasms.

Objective This study is to analyse the clinical feature and risk factors of morbidity after pulmonary resection for lung cancer in patients older than 70 years. Methods The clinical records of 222 patients older than 70 years who had undergone pulmonary resection for their lung cancer was reviewed. The patients were divided into 3 groups: group Ⅰ including the patients who had severe postoperative complications, group Ⅱ including the patients who had mild complications and group Ⅲ including the patients who had no complications. Moreover, the definitions were made that group A1 = group Ⅰ+ Ⅱ , group B1 = group Ⅲ, group A2 = group Ⅰ and group B2 = group Ⅱ + Ⅲ. Univariate analyses and multivariate binary logistic regressions relating postoperative morbidity to risk factors were performed between the group Al and Bl, A2 and B2, resulting in the identification of the independent risk factors for overall morbidity and major morbidity. Results Preoperative comorbidity was recorded in 161 patients (72.5%). Lobectomy (64.9% ) was the predominant surgical procedure. The median number of dissected LN was 14, with the range of 0 to 57. The overall morbidity was 63.5% , including major morbidity of 13.5%. Perioperative mortality was 1.8% (4 cases). The results of binary logistic regression analyses indicated that the independent risk factors for overall morbidity were preoperative weight loss (P =0.020), ASA score (P＜0.001), MVV (% predicted) (P=0. 020 ) and the number of dissected LN ( P = 0.004 ). The independent risk factors for major morbidity were ASA score ( P =0.003), MVV (% predicted) (P= 0.018) and the location of tumor (P=0.007). Conclusion Preoperative weight loss and numbers of dissected mediastinal lymph nodes were risk factor for lung cancer patients older than 70 years, Proper perioperative management for the elderly patients with high ASA score, low MVV (% predicted) or central tumor, could reduce the major postoperative morbidity.

OBJECTIVE:To evaluate therapeutic efficacy of Xuebijing injection in the treatment of severe craniocerebral trau-ma. METHODS:67 patients with severe craniocerebral trauma selected from neurosurgery department of our hospital were Treat-ment method divided into treatment group(33 cases)and control group(34 cases). Observation group was given conventional treat-ment,i.g. oxygen inhalation,dehydration,nourish cranial nerve,anti-infection. Treatment group On the basis of the control group was given Xuebijing injection 50 ml/time,tid,ivgtt. PT,TT,PLT,FIB,CK,LA, D-D,blood gas index (PaCO2,PaO2, HCO3-)of 2 groups were observed after 7 days of treatment,and prognosis of 2 groups were evaluated after 6 months as well as therapettin efficacy. RESULTS:After treatment,PT,TT,PLT,FIB,CK,LA, D-D,PaCO2,PaO2 and HCO3- of 2 groups were all better than before,and the treatment group was better than the control group,with statistical significance (P<0.05). The rate of good prognosis in treatment group (78.79%) was significantly better than in control group (55.88%) after 6 months of treat-ment,with statistical significance(P<0.05). CONCLUSIONS:Xuebijing injection in the treatment of severe craniocerebral trau-ma can improve coagulation function,blood gas levels and the inflammatory reaction,and is conducive to improve the patient's prognosis.

Objective To study the male reproductive ability of male rats with Toxoplasma gondii ( Tg) infection and investigate the variation of Toxoplasma infection in seminal plasma of infertile patients and explore its mechanism. Methods Thirty SD rats were randomly divided into 3 groups. The rats in the Toxoplasma infection group were administrated intraperitoneally with tachyzoites of Tg. in a dosage of 2 × 10~ 5/ml(2ml) , the rats in the treated group were administered with the same dosage of the tachyzoites and from the second day after the infection they were treated with 200 mg/kg azithromycin for 7 days, and the normal group was given physiological saline. Nine weeks after the infection, the serum sex hormone level, number,vitality, activity and quantity of spermatozoa and activities of enzymes in testa's of the testicular tissues were determined in the male rats. The female rats infected with Tg were matched with normal female rats at a ratio of 1: 2 for one week, and on the 21st day of pregnancy, the number of corpora luteum, sex ratio and the weight, body length and tail length of fetus were measured. The ELISA method was used todetermine the seminal plasma's anti-Tg IgG antibody of the 169 patients with infertility and 35 males with normal fertility. Meanwhile the NO levels in their semina were determined by means of nitric acid reducase. Results The number, activity .vitality, serum level of sex hormones were all lower in the infected rats than those in the normal and treated groups. The number of fetus in the pregnant rats matched with the infected male rats was significantly fewer, but the average body weight, body length, tail length of the fetuses and sex proportion showed no significant difference in comparison with those of the control group. The anti-Toxoplasma gondii antibody positive rate in the masculine infertility patients was 18.35% , being significantly higher than 2. 86% in the normal fertility group(P < 0.05 ). The mean NO level in the semina from the infertility group was (146.68 ± 38. 87) μnol/L , which was significantly higher than (84.92 ± 26.72) μnol/L( P < 0.01) in the fertility group. Conclusion Toxoplasma gondii infection can cause certain influences on the male reproductive ability.
