Objective To investigate the effects of different positions of the patients mechanically ventilated under general anesthesia on respiratory mechanics during one or both lung ventilation before thoracotomy.Methods Twelve ASA Ⅰ or Ⅱ patients of both sexes (8 males, 4 females) aged 33-63 years weighing 62-85 kg scheduled for general thoracic surgery were studied. The preoperative lung function of the patients was normal. The patients were premedicated with intramuscular pethidine, promethazine and atropine. Anesthesia was induced with fentanyl, droperidol, midazolam, propofol and vecuronium. Left-sided double-lumen tube was inserted and correct placement was confirmed using a fiberoptic bronchoscope inserted through the bronchial lumen. Anesthesia was maintained with propofol and vecuronium infusion. The magnitude of neuro-muscular blockade was monitored by stimulation of radial nerve with TOF pulses. T4/T1 was maintained at 0 during study. The patients were placed in supine, left and right lateral position. In each position both lungs, left and right lung were ventilated for 10 min respectively. The non-ventilated bronchial lumen was open to the air during one-lung ventilation. The ventilatory parameters were kept unchanged during the study (VT = 8-10 ml?kg-1 , RR = 12 bpm, I:E = 1:2). Pressure-volume loop (P-V loop), peak airway pressure (Ppeak), airway resistance (Raw), total compliance (CT) (lung and thorax) and PETCO2 were measured and recorded at the end of each 10 min ventilation using S/5 monitor ( Datex-Ohmeda Finland) . Results During both lung ventilation Ppeak was significantly increased and CT was significantly decreased in left and right lateral position as compared with supine position ( P

0.05). Conclusions In han-nationality people in Northern China, DRB1*04 is positively associated with Eales′ disease, suggesting that DRB1*04 may confer a major influence on Eales′ disease. Turbulence of immune function begotten by infect-agents attack may occur in the individuals with Eales′ disease due to the specific hereditary diathesis of HLA, which may cause the occurrence and development of Eales disease.

BACKGROUND:Osteofascial compartment syndrome is usual y due to application of external fixation for fracture treatment. Vaseline gauze is used to cover and compress the wound. Frequent dressing change induces infection and is harmful to wound drainage and tissue granulation, final y causing prolonged time of hospitalization and bad results. <br> OBJECTIVE:To investigate the clinical efficacy of Ilizarov external fixation combined with vacuum sealing drainage treatment for limb fractures with osteofascial compartment syndrome. <br> METHODS:A total of 32 patients with limb fractures with osteofascial compartment syndrome were randomly divided into two groups. Al patients adopted the same fasciotomy and drug treatment. In treatment group, the fracture was fixed with Ilizarov external fixation and the wound was covered with the vacuum sealing drainage dressing. In control group, the fractures were treated by unilateral external fixation and the wound was covered with the vaseline gauze. The fracture healing, clinical effects, hospitalization duration and costs between two groups were compared. <br> RESULTS AND CONCLUSION:In the treatment group, there were 10 cases of healing wel , 4 cases of muscle contracture and 2 cases of amputation. In the control group, there were 7 cases of healing wel , 6 cases of muscle contracture and 3 cases of amputation. No significant difference in clinical outcome measures was detected between the two groups. Fracture healing rate and costs were higher in the treatment group than in the control group (P<0.05), but hospitalization duration, skin grafts and the incidence of infection were lower in the treatment group than in the control group (P<0.05). Results suggested that on the basis of timely fasciotomy and decompression, Ilizarov external fixation combined with vacuum sealing drainage treatment for limb fractures with osteofascial compartment syndrome has a high limb salvage rate, which can effectively treat fractures, elevate the healing rate of fractures, reduce infection rate and skin grafting rate, shorten hospital stays. However, the hospitalization expense is higher.

Objective To investigate the epidemiological characteristics and therapeutic strategies of patients infected with hepatitis C virus (HCV)genotype 6 in Guangxi area.Methods Serum samples were collected from 150 patients with serologic HCV RNA positive in Guangxi, China. Reverse transcription nested polymerase chain reaction (PCR)was employed to amplify HCV NS5B fragments and the DNA products were sequenced.The sequences obtained were compared with the sequences deposited in GenBank to construct a phylogenetic tree.Among the patients who accomplished 48-week treatment of interferon plus ribavirin and 24-week follow-up after stopping medication,10 cases were infected with genotype 6a and 28 cases with genotype 1 HCV.The virological responses were evaluated at week 4,week 12,week 24 of treatment and week 24 after the end of the treatment.Results Among all recruited 150 cases,21 (14.0%)cases were HCV genotype 6 including two subtypes 6a (n = 20 )and 6d (n = 1 ). Genotype 6 HCV mainly affected intravenous drug users, especially with age of ≤ 40 years old. Phylogenetic tree showed that there was very close evolutionary distance between HCV 6 strains of Guangxi and Hongkong,China strains (Y12083,DQ 480515)and Vietnam strain (EU246930).All of 10 HCV genotype 6a patients who completed 48 weeks of antiviral therapy achieved sustained virological response (SVR).The rate of SVR was higher than that of genotype 1 patients,but without statistically different significance (10/10 vs 75 .0%,P >0.05).Conclusion HCV genotype 6 in Guangxi area mainly affects young intravenous drug users with age of ≤ 40 years old,which has high homology with Hongkong,China and Vietnam standard strains.Patients with HCV 6 genotype infection treated with interferon plus ribavirin for 48 weeks usually achieve favorable SVR.

AIM: To study the interaction effects of Astragalus polysaccharide(APS) and total glucosides of paeony(TGP) with various dosage on the platelet aggregation. METHODS: Platelet aggregation was estimated by the turbidimetric method. The best interaction effects were determined by uniform design method. RESULTS: APS showed apparent anti-platelet effects and better combination with TGP,and the ratio of 121 was the best one. CONCLUSION: APS concerted with TGP inhibits platelet aggregation.

Objective To observe and compare the efficacy and safety between propofol-remifentanil and propofol-fentanyl for anesthesia of artificial abortion.Methods 200 ASA I patients scheduled for painless artificial abortion were randomly divided into two groups.R group were given intravenous remifentanil 1.0μg/kg then propofol 1~1.5mg/kg(n=100);F group were given intravenous fentanyl 0.05mg then propofol 1~1.5mg/kg(n=100).Total propofol dosage,analgesic effect during intro-and post-operative,consciousness loss time,wake-up time and independenly leaving time were recorded.BP,HR,SpO2 and side effects such as nausea and vomiting were observed during intro-and post-operative.Results The dosage of propofol was less in group R than that in group F[(80.4±10.8)mg vs(110.1±13.6)mg,P<0.01)];consciousness loss time,wake-up time and independenly leave hospital time were shorter in group R than that in group F(P<0.05);SpO2 down range and rate were significandy higher in group R(P<0.05);Incidence of nausea and somnolence in group R was obviously lesS than that in group F.Conclusion Artifical abortion can be preformed effectively and safely with propofol-remifentanil or propofol-fentanyl,but propofol-remifentanil especially fits for painless artificial abortion compared with propofol-fantanyl.

[Objective] To investigate the effect of naringin at different doses on the neuropathie pain produced by lumbar 5 spinal nerve ligafion (L5 SNL). [Methods] Using the method of behavioral test, we tested the 50% paw withdrawal threshold before and after intragastrieal application of naringin in the rats with L5 SNL. [Results] Naringin at 30, 90, 100 mg/kg but not at 10 mg/kg increased the 50% paw withdrawal threshold of 1.5 SNL rats significantly. Single application of Naringin (at 30 or 90 mg/kg) inhibited mechanical allodynia for around 6 hours, and the inhibitory effect persisted for 4 days after the cessation of the drug when naringin (30 mg/kg, daily) was consecutively applied for 7 days. [Conclusion] Intragastrical of naringin could relieve the neuropathic pain produced by peripheral nerve injury.
