Objective To investigate the effect of malignant tumor on neuromuscular block of cisatracurium. Methods Sixty ASA Ⅰ or Ⅱ patients with head and neck neoplasms (15 cases with benign tumor, 45 with malignant tumor), aged 18-64 yr, were randomly divided into 4 groups ( n = 15 each): Ⅰ benign tumor group (group B,3 × ED95 ); Ⅱ -Ⅳ different dose cisatracurium group (group C1 (2 × ED95 ), C2 (3 × ED95 ) and C3 (4 ×ED95)). Neuromuscular block was assessed with accelerograph F (TOF-watch SX). Single stimulation of ulnar nerve was used. Anesthesia was induced with TCI of propofol (target plasma concentration 3 μg/ml) and remifentanil (target effect-site concentration 3 ng/ml). Tracheal intubation was facilitated with cisatracurium 0.15 mg/kg in group B, and with cisatracurium 0.10, 0.15 and 0.20 mg/kg in group C1, C2 and C3 respectively. The onset time, clinical duration, time for recovery of T/Tc to 75 % and recovery index were recorded. Results The clinical duration, time for recovery of T/Tc to 75 % and recovery index were significantly longer in group C2 than in group B (P ＜ 0.05). The onset time was significantly shorter, while the clinical duration and time for recovery of T/Tc to 75% were significantly longer in group C2 and C3 than in group C1 , and in group C3 than in group C2 ( P ＜0.05) .Conclusion The duration of action and recovery times of cisatracurium were prolonged in patients with malignant tumor.

Objective To evaluate the effects of volume therapy with different doses of 6% hydroxyethyl starch 130/0.4 (6% HES 130/0.4) on lung injury in a rat model of hemonhagic shock.Methods Twenty-four male SD rats weighing 220-300 g were randomly divided into 4 groups ( n = 6 each) : group I sham operation (group S); group II Ringer's solution (group RS); group HI and IV 2 HES groups (group H1, H2 ). The animals were anesthetized with intraperitoneal 1% sodium pentobarbital 45 ing/kg. Right common carotid artery (CCA) and left femoral vein were cannulated for blood letting, MAP monitoring, fluid administration and blood sampling. Hemonhagic shock was induced by withdrawing blood from right CCA in group II , III and IV . MAP was reduced to 35-45 mmHg which was maintained for 90 min. In group RS, hemorrhagic shock was resuscitated with Ringer's solution 3 times of the volume of blood withdrawn, while group H1 and H2 received HES 33 and 50 ml/kg respectively and Ringer' s solution (the total volume was equal to 3 times of the volume of blood removed) . Arterial blood samples were taken before blood letting (T0 , baseline), and at 2, 3 h after volume therapy (T1,2) for blood gas analysis and PaO2/FiO2 was calculated. The animals were then sacrificed by exsanguination and the lungs were immediately removed for microscopic examination and determination of protein concentration in broncho-alveolar lavage fuid (BALF), W/D lung weight ratio and TNF-α, IL-1 β and IL-10 contents in the lung.Results TNF-α, IL-1β and IL-10 content in the lung, protein concentration in BALF and W/D ratio were significantly higher in group RS, H1 and H2, while PaO2/FiO2 was significantly lower at T,2 in group RS and at T2 in group H2 than in group S (P < 0.05). TNF-α and IL-1β contents in the lung, protein concentration in BALF and W/D ratio were significantly lower in group H1 and H2 , while PaO2/FiO2 was significantly higher at T,i2 in group H1 and at T1 in group H2 than in group RS (P <0.05) . PaO2/FiO2 at T2 and IL-10 content in the lung were significantly lower in group H2 than in group H, ( P < 0.05) . The lung damage was significantly ameliorated in group H1 and H2 especially in group H, as compared with group RS. Conclusion Volume therapy with 6% HES 130/0.4 33 or 50 ml/kg can attenuate lung injury in a rat model of hemorrhagic shock and the efficacy of 33 ml/kg is better.

Aim To investigate the effects of 6% hydroxyethyl starch 130/0.4(6%HES 130/0.4)and Ringer's solution resuscitation on early lung injury in hemorrhagic shock rats and its mechanisms.Methods Twenty-four male SD rats were divided into 4 groups:sham,Ringer's solution(RS),two HES groups(H1,H2).Group H1,H2 received HES 33,50 ml·kg~(-1) and Ringer's solutions respectively after 90-minute shock(the dose of Ringer's solutions was 3 times as muchas the maximum shed blood volume minus the dose of HES).Blood samples were taken from artery for blood analysis and the expression of CD11b/CD18 at T_0,T_1,T_4,T_5.The lungs were removed for ultrastructure examination.Results PaO_2 increased in group H1 at T_(1～5) and group H2 at T_5 as compared with T_0.PaCO_2 decreased in all the resusitation groups.The ultrastructure was basically normal except that the mitochondria changed slightly in group H1.In group H2,the perinuclear space was dilated slightly and the rough endoplasmic reticulum expanded slightly,and the degranulation was observed.Compared with group RS,the expressions of CD11b and CD18 decreased at T_4,T_5;compared with group H1,the expressions of CD11b and CD18 in group H2 increased.Conclusions Treatment with 6%HES(130/0.4)33 ml·kg~(-1)and Ringer's solution can attenuate hemorrhagic shock,and the resuscitation reduces lung injury through inhibition of expressions of CD11b and CD18.

Objective To evaluate the effects of gender and age on median-effective target plasma concentration(EC50)of propofol administered by target controlled infusion(TCI)causing respiratory depression.Methods Eighty ASA Ⅰ or Ⅱ patients aged 40-79 yr,with body mass index 18-25 kg/m2.undergoing general anesthesia were divided into 4 groups(n=20 each):1 middle-aged male group(MA);Ⅱ middle-aged female group(FA);Ⅲold male group(MO) and Ⅳo ld female group(FO).No premedication was administered.Propofol Was administered by TCI for 15 min,using TCI system incorporating Marsh pharmacokinetic model.EC50 Was determined by up-end-down sequential trial.The target plasma concentration(Cr)was set at 3.1μg/ml in the first Patient in each group.Each time Cr increased/decreased by 10%in the next patient depending on whether or not the respiratory depression occurred.Respiratory depression was defined as RR<8 bpm,Vr≤5 ml/kg,end-tidal PCO2≥50 mm Hg,SaO2≤94%and/or apnea≥15s.Results The EC50 and 95%confidence interval of propofol TCI causing respiratory depression were 6.40(6.09-6.72)μg/ml in group MA,5.93(5.54-6.34)μg/ml group FA,4.58(4.32-4.91)μg/ml in group MO and 4.37(4.14-4.61)μg/ml in group FO.EC50 was significantly lower in group FO than in group FA and in group MO than in group MA,but there Was no significant difference in EC50 between group MA and group FA or between group MO and FO. Conclusion The potency of propofol given by TCI causing respiratory depression is increased in the old patients as compared with the middle-aged patients and is not related to sex.

Objective To investigate the effects of sufentanil,remifentanil and fentanyl oH cellular immune function in patients undergoing radical resection of esophageal cancer.Methods Forty-five ASA Ⅰ or Ⅱpatients aged 45-64 yr undergoing radical resection of esophageal cancer were randomly divided into 3 groups(n=15 each):sufentanil group(SF);remifentanil group(RF)and fentanyl group(F).The patients were premedicated with iv atropine 0.5 mg.Anesthesia was induced with midazolam 0.04 mg/kg,propofol TCI(CT=3μg/ml)and TCI of sufentanil,remifentanil or fentanyl(CT=0.5,5 and 5 ng,ml respectively in the 3 groups).Endobronchial intubation was facilitated with vecuronium 0.1 mg/kg.The patients were mechanically ventilated.PETCO2 was maintained at 30-40 mm Hg.Anesthesia was maintained with inhalation of sevoflurane(0.7-1.5 MAC)and TCI of sufentanil,remifentanil or fentanyl(CT=0.5,5 and 5 ng/ml respectively).Venous blood samples were taken from peripheral vein before anesthesia(T0,baseline),60 min after skin incision(T1),immediately(T2),24 h(T3)and 72 h(T4)after the end of operation for determination of the expression of CD3+,CIM+,CD8+on T cells and CD3-CD16+CD56+on natural killer cells by flow cytometry,CD4+/CD8+ratio,serum concentrations of IL-2 and IL-10 by ELISA.Results Compared with the baseline values,the CD4+T-lymphocytes and CIM+/CD8+ratio were significantly decreased at T2,while the CD3-CD16+CD56+NK cells were significantly increased in all 3 groups.The CD3+T-lymphocytes were significantly decreased at T2 as compared to the baseline value at T0 in SF and RF groups.The CIM+and CD3+T-lymphocytes were significantly decreased at T3 as compared with the baseline value in all 3 groups.Serum IL-2 concentration was significantly higher at T3 in SF group than in RF group.Serum IL-10 concentration was sismficantly higher at T4 in RF group than in SF group.Conclusion Sufentanil,remifentanil and fentanyl can depress cenular immune function to some extent in patients undergoing radical resection of esophageal cancer.

Objective:To investigate the ultrasound image and pathological features of invasive fibromatosis, and to provide a basis for the diagnosis of invasive fibromatosis.Methods:The clinicopathological data of 22 patients pathologically diagnosed with invasive fibromatosis from January 2016 to March 2019 in Shanxi Provincial Cancer Hospital were retrospectively analyzed. The clinical, ultrasound and pathological data were also summarized.Results:Ultrasound images of invasive fibromatosis showed irregular morphology, unclear boundaries, uneven echo, spot-like or strip-shaped blood flow signals. The coincidence rate of ultrasound diagnosis was 59.1% (13/22), 3 cases were misdiagnosed as fibrous, fat and other sarcomas, 4 cases were misdiagnosed as nerve-derived tumors, 1 case was misdiagnosed as nodular fasciitis, and 1 case was misdiagnosed as gastrointestinal stromal tumor. The pathological characteristics of invasive fibromatosis were more typical, and the positive expression rate of vimentin and β-catenin in immunohistochemistry was 100.0% (22/22); the coincidence rate of preoperative pathological diagnosis of puncture was 78.6% (11/14), 1 case was misdiagnosed as nerve fiber tumor, 1 case was misdiagnosed as low-grade fibromyxoid sarcoma, and 1 case was misdiagnosed as nodular fasciitis.Conclusion:Invasive fibromatosis has a certain specificity in ultrasound and pathological diagnosis, which can be diagnosed and differentially diagnosed according to the ultrasound image and pathological characteristics.

Objective: To explore the clinical value of three-dimensional computed tomography bronchography and angiography (3D-CTBA) in thoracoscopic dissection or combined segmentectomy. Methods: The clinical data of 30 patients with isolated or multiple pulmonary nodules from September 2017 to August 2019 were retrospectively analyzed. All cases were treated with 3D-CTBA to locate the nodules accurately before operations, in order to explicit the courses of bronchi and vessels, and to observe the variations. The target bronchi, arteries and veins were resected accurately during the operations, and the intersegmental plane was determined by expansion-collapse method. Results: 13 patients underwent segmentectomy and 17 patients underwent combined segmentectomy. The diameter of the nodule was (11.56±3.79)mm; the depth of the nodule (the shortest distance from the visceral pleura) was (13.88±3.96)mm; the operation time was (134.94±18.68)min, and the intraoperative bleeding volume was (94.38±37.94)ml. No cancer metastasis was found by rapid pathological examination of lymph nodes during operations. No conversion to thoracotomy. The indwelling time of thoracic tube was (3.69±1.30)days, and the hospitalization days after operations was (4.81±1.47)days. No serious complications or death during the perioperative period. Conclusions Preoperative 3D-CTBA has advantages in pulmonary segmentectomy, which is a safe and effective method for accurate segmentectomy.

Systemic lupus erythematosus (SLE) complicated with Aspergillus fumigatus brain abscess is rare and needs to be differentiated from bacterial brain abscess and neuropsychiatric lupus. This article reports 2 cases of surgically diagnosed SLE combined with Aspergillus fumigatus brain abscess. The first patient was a 34-year-old woman. Six months after the diagnosis of SLE, she developed convulsions and unconsciousness. She was diagnosed as neuropsychiatric lupus at the first hospitalization because of negative imaging. After discharge, repeated head magnetic resonance imaging revealed abscess-like signals. The second patient, a 20-year-old male, developed high fever, convulsions, and unconsciousness 3 years after the diagnosis of SLE, and head imaging showed an abscess-like signal. The etiology of the cerebrospinal fluid of the 2 patients was both negative, and the Aspergillus fumigatus brain abscess was diagnosed by pathology through abscess resection or drainage. After treatment with voriconazole, the symptoms were relieved and the lesions were subsided.

Objective:To explore the relationship of risk factors and clinical features to assessments of children with cerebral palsy (CP ) using a magnetic resonance imaging classification system (MRICS).Methods:Medical records of CP patients under 18 years old were reviewed retrospectively. Data including high-risk factors, cranial MRI results and clinical characteristics were collected. The cranial MRI results were classified according to the MRICS.Results:Of 1357 patients studied, 1112 (82%) had received cranial MRI scans. Among them, 962 (86.5%) showed MRI-identified brain abnormalities, 489 in the periventricular white matter. Subjects with different weeks of gestation, birth weights, delivery times, neonatal hypoxic-ischemic encephalopathy, and neonatal cerebral hemorrhage had significantly different MRI classifications according to the system. Premature birth, low birth weight and multiple births correlated with the incidence of white matter brain injury. Only 4 of the subjects with neonatal cerebral hemorrhage were classified as having normal brain structures using the MRICS. However, gender, birth method, and pathological jaundice had no significant relationship with MRICS ratings. Significant differences in MRICS classifications were observed between patients with different CP subtypes, gross motor function scores, as well as with or without epilepsy, speech or language impairment. But degrees of mental retardation were not significantly related with MRICS classifications.Conclusion:MRICS classifications relate closely with risk factors and the clinical characteristics of CP patients. The system can play an important role in finding pathogenesis and predicting clinical outcomes. It is worthy of applying and promoting in the clinic.

Objective:To investigate the efficacy, feasibility, and safety of task-oriented exercise training for hospitalized elderly diabetic patients.Methods:This study is a parallel randomized controlled trial with a positive control and a single-blinded assessor.From July 2020 to July 2021, we included 84 elderly patients with type 2 diabetes who were hospitalized in the Department of Endocrinology at Beijing Hospital.These patients were randomly divided into two groups: the task-oriented exercise training group(TOE group)and the regular exercise training group(regular group). The TOE group participants were trained using a task-oriented exercise program that was specifically developed by our research team.On the other hand, the regular group participants were trained using a classical program that comprised of all exercise modes.Each subject received individualized exercise training for 10 consecutive days while staying in the hospital.We evaluated the efficacy, feasibility, and safety of the training programs by measuring the physical fitness of the participants, assessing the feasibility of the program, and monitoring any exercise-related adverse events that occurred.Results:A total of 79 subjects completed the entire intervention and follow-up period, with 40 subjects in the TOE group and 39 subjects in the regular group.In terms of efficacy, both groups showed improvement in their physical fitness indexes after the intervention, with no significant differences in the degree of improvement between the two groups(all P>0.05). When considering feasibility, the TOE group had a higher proportion of prospective feasibility at 87.5%(35 out of 40)compared to the regular group at 71.8%(28 out of 39). Similarly, the TOE group had a higher proportion of practical feasibility at 75.0%(30 out of 40)compared to the regular group at 53.8%(21 out of 39). The TOE group showed a significant advantage in practical feasibility between the two groups( χ2=3.862, P=0.049). As for safety, there were no exercise-related adverse events during the intervention in either group. Conclusions:The efficacy and safety of the task-oriented exercise program for hospitalized elderly diabetic patients is comparable to that of the regular program.Additionally, the task-oriented program is more feasible than the regular program.
