OBJECTIVE:To analyze the general patterns and characteristics of drug-induced lupus (DIL) induced by inflix-imab,and to provide reference for the safety of drug use. METHODS:Usinginfiximab,lupusas searching words,inflix-imab-induced DIL literatures included in CJFD,VIP and PubMed from Jan. 2002 to Jun. 2016 were retrieved and analyzed. RE-SULTS:Totally 30 effective literatures were retrieved,involving 31 DIL patients,there were 8 male cases (25.81%) and 23 fe-male cases(74.19%);17 patients aged more than 50(54.84%). 20 cases occurred within 5-24 weeks(64.51%). 16 patients re-ceived infliximab alone (51.61%). Main clinical manifestations were skin rash or photosensitivie enteritig (15 cases),joint pain (16 cases,multiple arthritis and synovitis)and fever(12 cases). 5 patients suffered from 3 above symptoms simultaneously. Labo-ratory examination mainly manifested as antinuclear antibody,double stranded DNA antibody and anti-histone antibody positive. Thirty patients with DIL received drug withdrawal or steroid hormones treatment,among which the symptoms of 26 patients disap-peared after drug withdrawal or treatment within 6 months,and 1 patient deteriorated. CONCLUSIONS:DIL-induced by inflix-imab invovle patients'age and gender,disease types,family history and other factors. Clinicians should be aware of rules and char-acteristics of DIL induced by infliximab,and tighten drug use monitoring to reduce ADR.

Objective To explore the difference between pressure-regulated volume controlled ventilation (PRVCV) and volume controlled ventilation (VCV) during videothoracoscopic bhb excision.Methods Consecutive 20 patients scheduled to undergo videothoracoscopic bleb excision were enrolled into the study.After induction, endotracheal blocker was advanced into endotracheal tube to establish one-lung ventilation,each patient was randomly assigned to receive successively PRVCV and VCV for 20 minutes.Ventilatory variables were kept constantly(tide volume 6 ml/kg, respiratory rate 15 breaths/min and I: E ratio 1: 2).Heart rate,blood pressure,peak airway pressure and blood gas parameters were compared.Results Peak airway pressure was significantly lower with PRVCV than that with VCV [(12.7±3.6 ) cmH_2O(1 cm H_2O =0.098 kPa) vs (18.2±4.3) cm H_2O,P < 0.01].However,there was no significant difference in arterial oxygen tension,arterlal partial pressure of carbon dioxide,heart rate and blood pressure between PRVCV and VCV.Conclusion During one-lung ventilation in videothoracoscopic bleb excision, PRVCV offers lower peak inspiratory airway pressures while maintaining equal oxygenation compared with VCV.

Objective To study the effect of endotracheal tube's resistance on the respiratory systolic variation test(RSVT).Methods The RSVT,a test to predict fluid responsiveness was performed in 20 patients.The test consisted of the delivery of three congecutive pressure-controlled breaths with incremental peak inspiratory pressures of 10,20 and 30 cm H2O(1 cm H2O=0.098 kPa).The minimal values of the systolic arterial pressure following each of these three breaths were measured and plotted against their respective airway pressures,producing the RSVT slope.RSVT slope were compared between normal airway resistance and increased resistance circumstances,and the latter was simulated by advancing a Cooperdech bronchial blocker into endotracheal tube.Results Under normal resistance,RSVT slope was(0.39±0.21) volumes were(461.5±95.9),(891.5±149.8)and(1207.5±159.1)ml,when peak inspiratory pressures of 10,20 and 30 cm H2O were dehvered.When bronchial blocker was advanced into endotrecheal tube, (0.27±0.17)mm Hg,cm H2O significantly(P<0.01),and tidal volumes decreased to(434.5±92.8), (796.5±96.6)and(1097.5±68.4)ml(P<0.05 or<0.01).Conclusion Changes in endotraeheal tube's resistance can distort the RSVT slope.

To identify the best inducing condition, we studied the expression of membrane protein HSP70 and mRNA of H22 cell at various temperature. Using MTT,RT-PCR, immunofluorescence and FCM techniques, we observed H22 cell survival rate, the expression of HSP70 mRNA and membrane HSP70. No effects of H22 cell survival rate under 42 ~ 43℃ was observed, but cell survival rate declined with increasing stress time at 44 ~ 45 ℃; the level of HSP70 mRNA decreased initially (0.5~4.0) hours but gradually resumed and increased from 8 to 12 hours at 42℃. Membrane HSP70 expressing cells were significently higher in heat shock treatment group than in a control group ( P

Objective To compare the effects of target-controlled infusion (TCI) of propofol and remifentanil and inhalation anesthesia on the stress response in patients undergoing laparoscopic cholecystectomy (LC). Methods Selective LC was performed on 60 cases. Before the surgery,the patients were randomly divided into experiment (TCI of propofol and remifentanil) and control (standard general anesthesia combined with inhalation of fluorinated alkane and laughing gas) groups with 30 cases in each. The serum levels of cortisol and IL-6 were detected before the induction (t1) and 20 minutes after pneumoperitoneum (t2). In addition,the MAP and HR of the two groups were monitored at seven time points. Results The serum levels of cortisol and IL-6 in the experiment group were similar to those in the control at t1 [Cortisol:(227.48?50.81) ?g/L vs (233.21?41.02) ?g/L,t=0.481,P=0.633; IL-6:(105.99?30.65) ng/L vs (111.20?34.80) ng/L,t=-0.615,P=0.541],but significantly lower at t2 [Cortisol:(241.00?69.11) ?g/L vs (354.70?37.55) ?g/L,t=7.918,P=0.000; IL-6:(116.06?30.89) ng/L vs (172.73?23.54) ng/L,t=-7.992,P=0.000]. The MAP and HR in the experiment group were significantly lower than those in the control at t2 to t5 (5,10,15,and 20 minutes after the pneumoperitoneum; P

Objective To study the clinical characteristics, diagnosis, treatment and prognosis of cancer metastasis to the thyroid gland. Methods A restropective review was performed on 35 patients with cancer metastasis to the thyroid gland in our hospital from 1958 to 2010. Diagnosis was confirmed by fineneedle aspiration cytology or histopathology in all cases. Results Primary tumor origin was identified in all but three cases. The lung was the most common primary tumor site( n = 16), followed by esophagus( n =9),breast ( n = 2), kidney ( n = 2), hypopharynx ( n= 1 ), nasopharynx ( n = 1 ) and soft palate ( n = 1 ). Thyroid metastasis was found before the diagnosis of the primary tumor was established in 12 cases; in the other 23 cases, the time lapse from diagnosis of the primary tumor to metastasis to the thyroid gland ranged from 0- 168 months, median 24 months. In 6 patients, this interval was more than 36 months. Fine-needle aspiration cytology ( FNAC ) confirmed metastatic malignancy in 7 patients, histology in 24, combined application confirmed the diagnosis in 4. After the metastasis to the thyroid gland was established, the median survival time for the entire group was 11.5 months, the 1-, 3- and 5-year survival rate was 43.8%,27. 8% and 11.9%, respectively. 28 patients were treated surgically, and 7 received nonsurgical therapy.The overall survival rate in the surgical group was higher than that in the nonsurgical group (P ＜0. 01 ). In those patients with metastatic cervical lymph nodes, median survival time did not vary from patients undergoing thyroidectomy with neck dissection to those undergoing thyroidectomy alone (P ＞ 0. 05 ).Conclusions Metastasis of carcinoma to the thyroid gland has an occult occurrence, thyroid metastases can be detected conclusively with FNAC. Metastasis to the thyroid gland implies advanced malignant tumors,often with poor prognosis.

Objective To investigate the effects of Mailuoning on oxidative stress and ischemic brain injury. Methods A total of 126 healthy male Kunming mice were divided into sham operation (n = 18), normal saline control (n = 54) and Mailuoning (n = 54) groups. A middle cerebral artery occlusion (MCAO) model was induced Two hours after MCAO,Mailuoning injection and equivalent saline were injected via the tail vein in the Mailuoning and normal saline control groups, respectively, and then they were injected every other 24 h.Neurological score was performed, and brain water content, infarct volume, membrane potential,as well as protein oxidative stress metabolites such as 3-nitrotyrosine (3-NT), lipid oxidative stress metabolite 4-hydroxy-2-nonenal (HNE) and nucleic acid oxidative stress metabolite 8-hydroxy-2'-deoxyguanosine (8-OHdG) were detected at 12, 24 and 72 h after MCAO. Results Mailuoning injection could significantly improve the neurological function of cerebral ischemia in mice, decrease brain edema, and reduce infarct volume at different time points after cerebral ischemia Of those, it was most significant at 72 h. Mailuoning injection could reverse the decreased mitochondrial membrane potential in cerebral cortex and internal capsule, and significantly downregulate the increased 3-NT, HNE and 8-OHdG in cerebral cortex, internal capsule and serum after ischemia, of those, the effect of reducing HNE was most significant.Conclusions Mailuoning injection may effectively protect against ischemic brain injury in mice,and its mechanism is associated with inhibiting oxidative stress, particularly anti-lipid oxidation.
