Clinical Medicine of China 2008;24(8):787-789
Objective To explore the prognostic factors in patients with acute respiratory failure due to chronic obstructive pulmonary disease (COPD) in EICU. Method Clinical data of 39 patients admitted to EICU from May 2005 to May 2007 were retrospectivley analyzed. Results In death group, the pulmonary artery pressure (PAP) ,creatinine (Cr) ,APACHE-Ⅱ score, and APACHE-Ⅲ score were increased (P < 0. 05) and ICU stays were prolonged (P < 0.05) ; Respiratory rate (RR) and Glasgow coma score (GCS) were decreased (P < 0.05). Conclusion PAP, Cr, APACHE-Ⅱ score,APACHE-Ⅲ score,RR and GCS predict the prognosis of the patients with acute respiratory failure due to chronic obstructive pulmonary disease.

OBJECTIVE:To summarizethe application of polypropylene repair material in treating inguinal hernia.METHODS:Papers regarding polypropylene repair material in treating inguinal hernia published in VIP data between January 1998 and October 2009 were researched using key words of "polypropylene,inguinal hernia,and complication".Inclusion criteria Repairing inguinal hernia using polypropylene materials.Experimental results concerning related complications.Exclusion criteria:repetitive study and relatively old literature.A total of 17 documents were included in this study.RESULTS:Organic polymeric materials were clinical utilized in repairing inguinal hernia at the end of 1950s.The polypropylene patch was knitted by slngle fiber or multi-strands fibers of polypropylene,and exhibited single layer network structures,which is preferred material for repairing abdominal-wall defect.Compared with other unabsorble materials,the polypropylene patch had following advantage:obviously stimulating fibroplasias; easy permeated by fibrous tissues and embedded into tissues; maintaining highly tensile strength following implantation; and relative low cost.Few material-related complications occurred following repairing,mainly presented with infection,serofiuid swelling,ankylenteron,intestinal leakage,material displacement,as well as material shrinkage.CONCLUSION:Polypropylene material is an ideal repair material due to good histocompatibility,few rejections,and anti-infection capability.It leads to easy operation,small trauma,fast recovery and few complications in repairing defects.

The neuromechanism of language function recovery in patients with aphasia after stroke is still unclear. It is supported that the language function of aphasia after extensive damage of left hemisphere mainly recovered through activating the right hemisphere of ho-mologous regions to improve the function of speech. Melodic intonation therapy (MIT) can be achieved by melody tone and left hand clap to activate the right hemisphere of the frontal temporal lobe, which is particularly applicable to improve language function of non-fluent aphasia patients with large left hemisphere lesion. Non-invasive brain stimulation techniques (NBS) changes brain activity through stimulat-ing affected or contralateral side, which has been used to facilitate language functional recovery after stroke. Excitatory transcranial stimula-tion on the right hemisphere homology combined with melodic intonation therapy can promote language recovery of patients with extensive damage of left hemisphere after stroke. It is valuable to combine traditional speech training with MIT and NBS to activate related language functional areas to maximum improvement of language recovery after stroke.

Objective:To examine the effects of acute or chronic administration of 7-nitro indazole (7-NI) on the MAC of sevoflurane and cerebellar cGMP levels in mice. Method:In acute experiment,sevoflurane MAC was determined in mice after 7-NI 120mg/kg, 180mg/kg or 120mg/kg plus L-arginine 600mg/kg was given intraperitoneally. During chronic experiment, MAC was measured on 1st, 4th and 7th day during week-long gavage feeding of 7-NI. The levels of cerebellar cGMP also were measured after acute and chronic administration of 7-NI. Result:Acute administration of 7-NI 120mg/kg decreased sevoflurane MAC by about 20% and cerebellar cGMP level by 96%. 7-NI 180mg/kg did decrease MAC not more than 7-NI 120mg/kg. No significant reduction of MAC was observed in mice treated by intraperitoneal 7-NI 120mg/kg+L-arginine 600mg/kg. In chronic experiment,sevoflurane MAC and cerebellar cGMP were decreased significantly on 1st 4th and 7th day to the similar extend, with 15%-20% reduction in MAC and 46%-60% in cGMP levels. Conclusion:Acute and chronic selective inhibition of nNOS decreases sevoflurane MAC and cerebellar cGMP levels in mice. The maximal reduction (only about 20%) of MAC can be obtained when cGMP levesl are decreased about 50% and further inhibition of generation of cGMP does not produce more enhancement to the potency of sevoflurane anesthesia. No compensatory mechanism for the inhibition of L-Arg-NO-cGMP pathway appears during week-long treatment with 7-NI.

Objective To assess the value of thinprep liquid based cytology test (TCT) and Besthesda system (TBS) in diagnosis of cervial lesions. Methods 11000 cases of cervical lesions were detected with TCT and TBS.The samples of atypical squamous cells(ASC) and more severe than ASC lesions were classified into postive cytology,and then cytological results were compared with pathological examination results of cervical biopsies.Results The satisfactory rate of TCT samples was 96.36%, and the postive rate of abnormal epithelial cells diagnosed by TCT was 10.96%(1206/11000). Among 1206 cases, 15 cases(0.14%) of CA, 89 cases (0.81%) of HSIL, 449 cases (4.08%) of LSIL, 73 cases (0.66%) of ASC-H and 580 cases (5.27%) of ASC-US and AGUS. 1128 cases with postive cytologic results received pathological examination. The pathological positive rate of CA, HSIL, LSIL, ASC-H, and ASC-US and AGUS were 100%, 100%, 67.12%, 54.17% and 14.09%, respectively. The coincident rate of two examination methods was 100% for CA, 91.1% for HSIL,57.82% for LSIL and 27.78% for ASC-H. Conclusion TCT and TBS can accurately detect cervical cancer, precancerous lesions and infection of bacteria, virus and other pathogens, and at present is a means of screening cervical cancer.

Objective To compare the analgesic and side effects of tramadol, buprenorphine and morphine in equipotent dosage in patient-controlled intravenous analgesia (PCIA). Methods 53 patients (ASA I-II) scheduled for upper abdominal surgery were randomly allocated to receive 10mg/ml tramadol (group T) or 0.03mg/ml buprenorphine (group B) or 1mg/ml morphine (group M) plus 0.1mg/ml droperidol. Baxter APII PCA pump was used to administer the different analgesic according to the model of LCP, with the amount of loading dose, continuous infusion and bolus of 2.5ml, 0.5ml/h, 1ml respectively. At 4, 8, 16 and 24h postoperatively, pain scores in VAS, comfort scale in BCS, sedation scores with Ramsay score, and the incidences of nausea, vomiting, pruritus, respiratory depression were assessed. Drug consumption in the first 24h and the D/D ratio (demand/deliver) were also recorded. Results VAS and BCS scores showed no significant difference among the 3 groups, but drug consumption within the first 24h and the D/D ratio in group T were higher than those in other 2 groups (P0.05). 8 patients in group T, 5 in group B and 4 in group M suffered from nausea; 1 patient in group T, 2 in group B and 3 in group M complained of pruritus. No respiratory depression was observed in all cases. Conclusion Tramadol and buprenorphine can be safely used as PCIA in patients undergoing upper abdominal surgery, but they are not superior to morphine.

Objective To make the surgical therapy of urethral stricture and occlusion more effective. Methods 154 patients treated in our hospital were included in this retrospective study,of these cases,40 cases were in anterior urethra and 114 in posterior part.Based on etiology,106 cases were from trauma,15 from infection and 33 from idiopathic causes.Open surgery was performed on 34 cases and endoscopic therapy on 120 cases. Results All of the anterior urethral cases were treated successfully,among them,18 cases were with open surgery and 22 with endoscopic surgery.Normal urination was achieved on the follow-up from 6 months to 12 months.Within posterior urethral stricture and occlusion situation,open surgery was in 16 cases with 10 cases of normal urination and endoscopic surgery in 98 cases with 92 cases of normal urination.6 cases with open surgery and 5 cases with endoscopy resulted in postoperative dysuria or anuria.Urethral stricture and occlusion were shown in all these unsuccessful operation according to our urethrogram. Conclusions Good result can be achieved by both open and endoscopic surgery in anterior urethral stricture.In case of posterior urethral condition,endoscopic procedure is the best choice.
