BACKGROUND: The blood oxygen saturation is an important physiological parameter of human hfe; it can be affected by multiple factors due to the imbalance of oxygen supply and consumption, and consequently, the normal physical metabolism is affected. The existing manufacturing techniques are complex and are used with higher demands. OBJECTIVE: To investigate the accuracy of the novel reflecting oximeter designed on the basis of reflecting principle in monitoring the variance of blood oxygen saturation with the change of its concentration. DESIGN: To introduce the structure, working principle and design of the reflecting oximeter and make comparative study with adult rabbits as the subjects. SETTING: Cardiopolmonary Bypass Department of Cardiovascular disease hospital of the Chinese Academy of MedicalSciences. MATERIALS: The study was performed at the Departments of Anesthesiology and Cardiopulmonary Bypass of the Cardiovascular Disease Hospital,Chinese Academy of Medical Sciences from August to October in 2001.Ten adult rabbits were selected. METHODS: The oximeter consists of a converter, a driver, a central processing mould and liquid-crystal monitor. It is characterized by the onethree optical cable connected with reflecting probe, postcentral management system and digital displayer. This oxmeter was developed basing on the basis of fixed relationship between blood oxygen saturation and radiant absorbency (or reflecting). In this study,cardiovascular-pulmonary bypass was established on rabbits that were then exposed to oxygen and NO mixture supply of different concentrations,and then the corresponding blood oxygen saturations were determined with the new oximeter and compared with series-wound Baite saturation meter and blood-gas analysis. MAIN OUTCOME MEASURES: The blood oxygen saturation at different concentrations determined with the reflecting oximeter and Baite saturation meter. RESULTS: At the same oxygen concentration, the blood oxygen saturation determined with the new measure was not significantly different from that determined with Baite blood oxygen saturation meter(P＞0.05 ). CONCLUSION: The variance of blood oxygen saturation with the change of oxygen concentration can be detected by the reflecting oximeter with the result similar to that by Baite blood oxygen saturation meter.

Objective To explore the effect of manipulation on muscle tension and motor function of children with spastic cerebral palsy.Methods 80 children with spastic cerebral palsy were divided into observation group and control group with 40 cases in each group.Both groups were treated with exercise, acupuncture, electrotherapy, Chinese medicine steam bath. The observation group received massage treatment before and during exercise treatment. Modified Ashworth Scale (MAS) and Gross Motor Function Measure-88 (GMFM-88) were used to evaluate the muscle tension and motor function. Results 3 months after treatment, the MAS score decreased and the score of GMFM-88 increased significantly in both groups (P<0.001), and the MAS score was lower, and the score of GMFM-88 was higher in the observation group than in the control group (P<0.001). Conclusion Manipulation can further improve the muscle tension and the motor function of children with spastic cerebral palsy.

Objective To investigate the incidence rate of auditory nerve way injury in children with cerebral palsy (CP) and the relationship with sexes, CP types and risk factors.MethodsThe clinic data of 963 children with CP were reviewed to find out the incidence rate of auditory nerve way injury in CP children and the relationship with sexes, CP types and risk factors.ResultsIn 963 CP children, the incidence rate of auditory nerve way injury was 24.5% (236/963), there was no sexes difference ( P>0.05), but there was a significant difference among different CP types ( P<0.05), athetosis and mixed CP had higher incidence rate ( P<0.01). Furthermore, pathological jaundice was high risk factor ( OR=2.0279, 95%CI:1.483～2.774).ConclusionCP children are often complicated with auditory nerve way injury, it not relate with sexes, but with CP type, athetosis and mixed CP have a higher incidence rate of auditory nerve way injury, and the pathological jaundice is a high risk factors.

Objective To investigate the effects of ischemic postconditioning (Post) on myocardial cell apoptosis and expres- sion of Bcl-2 and Bax protein during ischemia/reperfusion period in rabbits.Methods Eighteen rabbits were randomly allocated to three groups (6 in each group),sham operation (group S),ischemia/reperfusion group(group IR) and ischemic postconditioning group(group Post).Group IR and group Post were subjected to 15 minutes of left anterior descending coronary artery occlusion followed for 30 minutes of reperfusion.Ischemic postconditioning was achieved by three 30 seconds cycles of reperfusion,each followed by 30 seconds ischemia.Cardiomyocyte apoptosis were determined by in situ TDT-mediated dUTP nick end labeling (TUNEL) and DNA electrophoresis.The expression of Bcl-2 and Bax proteins in apoptotic myocardial cells were detected by immunohistochemistry sepa- rately.Results Compared with group IR,apoptotic index was significantly reduced in group Post [(28.06?2.92) % vs.(55.70? 13.96)%,P

: Objective To evaluate the value of rehabilitation direction for the treatment of the children with spastic cerebral palsy. Methods 116 children with spastic cerebral palsy were investigated. 56 children who accepted rehabilitation direction and training in family participated in study group and 60 children who wouldn't accept rehabilitation direction participated in control group. All the children received comprehensive rehabilitation treatment in hospital, including physical therapy, acupuncture, low frequency electrotherapy and occupational therapy. All the children were assessed with Gross Motor Function Measure-88 (GMFM) before and 3 months after treatment. Results There was a significant difference before and after treatment in scores of GMFM in each dimension and total in both groups (P<0.01), and the treatment group improved more than control group(P<0.05). Conclusion Rehabilitation direction can facilitate the recovery of spastic cerebral palsy children.

Objective To observe the effect of core control training on gross motor function for children with cerebral palsy. Methods 40 cases were divided into 2 groups, 20 cases in each group. The control group accepted comprehensive rehabilitation, and the treatment group accepted core control training in addition. They were assessed with Gross Motor Function Measure (GMFM-88) before and 3 months after treatment. Results The score of GMFM-88 increased in both groups after treatment (P<0.001), and increased more in the treatment group than in the control group (P<0.05). The difference of GMFM-88 score was more in the treatment group than in the control group (P<0.001). Conclusion Core control training can improve gross motor function for the children with cerebral palsy.

Objective: To observe the distribution of occupational activity disorders of extremely severe mass burn patients in recovery period after injury. Methods: From December 2014 to December 2015, 65 extremely severe burn patients conforming to the inclusion criteria involved in August 2 Kunshan factory aluminum dust explosion accident were admitted to Kunshan Rehabilitation Hospital. They received comprehensive rehabilitation treatment after burns, including wearing pressure clothes, ultrasound treatment, semiconductor laser and red light irradiation, motor function training, and so on. Over 2 years after injury, a cross-sectional survey was conducted on the patients′ occupational activity disorders. Modified Barthel index (MBI) was used to assess the degree of activities of daily living (ADL) disorder of patients and to grade the independent level of completing each item of MBI, and then the independent level of patients completing self-care MBI items (bathing, dressing, grooming, eating, going to the toilet, urine control, and stool control) was compared with that of mobility items (going up and down stairs, bed and chair transfer, and walking). The Canadian Occupational Performance Measure (COPM) was used to assess the distribution of occupational activity disorders of patients. The distribution of the five most serious occupational activity disorders was counted, then the frequency and probability of which with frequency greater than or equal to 16 times were calculated. Data were processed with Pearson Chi-square test. Results: Over 2 years after injury, the MBI score of patients was (76±22) points, and the ADL of 83.08% (54/65) patients reached completely self-care or light ADL disorder level. The MBI items arranged according to the completing independent level of patients from high to low were urine control/stool control, walking, bed and chair transfer, going up and down stairs, going to the toilet, eating, grooming, dressing, and bathing. The independent level of patients completing self-care MBI items was lower than that of mobility items (χ²=62.298, P<0.001). Over 2 years after injury, the five most serious occupational activity disorders in COPM dimension were mainly concentrated in the self-care dimension, accounting for 55.38% (180/325), followed by 22.46% (73/325) of production activities and 22.15% (72/325) of recreational activities, and the centrally distributed item was the personal self-care item under self-care dimension, accounting for 42.46% (138/325). Over 2 years after injury, the five most serious occupational activity disorders with frequency greater than or equal to 16 times were dressing and undressing, bathing, perineal cleaning, wearing pressure clothes, caring for children, visiting relatives and friends, 31, 25, 16, 17, 18, and 22 times respectively, with a probability of 47.69%, 38.46%, 24.62%, 26.15%, 27.69%, and 33.85% respectively. Conclusions: Over 2 years after injury, most of the patients with extremely severe burns caused by the aluminum dust explosion were completely or basically self-care in their daily life. The disorder of self-care ADL was more serious than that of mobility, and the disorder of individual self-care activity was still the most serious occupational activity disorder of patients in this stage.

Hepatic ischemia-reperfusion injury is the most common complication after liver transplantation. Oxidative stress, autophagy, and inflammatory response caused by excessive reactive oxygen species production are significant steps that cause liver ischemia-reperfusion injury. What′s more, nuclear factor erythroid 2-related factor 2 is considered to be a major regulator of the antioxidant response, the PI3K-Akt-mTOR signaling pathway is considered to be an important pathway of autophagy, and the HMGB1-TLR4-NF-κB signaling pathway is considered to be a key signaling pathway which leads to inflammation. Based on the above signaling pathways and regulatory factor, this article shows that the antioxidant, anti-inflammatory and autophagy regulation effects of genes, molecules and drugs on hepatic ischemia-reperfusion cells, to explore the protective effects on hepatic ischemia-reperfusion cells.

Objective To summarize our clinical experience of cryoablation for renal cancer and to analyze the therapeutic indication,security,selection of cryoablation and outcomes.Methods Sixty-four patients suffered with T1a renal cell carcinoma were enrolled in this study from March 2012 to March 2018.Among them,5 cases were senile patients (≥ 80 years),5 cases complicated with other cancers,3 cases complicated with renal insufficiency,4 cases complicated with decompensated cirrhosis,3 cases with bilateral renal cancer,4 cases with solitary kidney cancer and 39 cases with some other complications.The preoperative serum creatinine level was(80.5 ± 38.2)μmol/L.The patients underwent laparoscopic singlesite (LESS) renal cryoablation,conventional laparoscopic renal cryoablation,or percutaneous image-guided cryoablation according to individual situation.Contrast-enhanced CT scan or MRI were used during the procedures and follow-up was performed.Results All operations were completed successfully and technical success was achieved as well in all cases.Blood transfusion was necessary for 2 cases because of hemorrhage.The mean diameter of the mass was (2.6 ± 0.90) cm,the median volume of blood loss was 50ml(10-110 ml),and the mean operation time was(96.0 ± 24.5) min.The median inpatient hospital stay was 3 d (1-6 d).In one case,digital subtraction angiography (DSA) embolization was performed due to hemorrhage after surgery.None of the other cases had intraoperative or postoperative complications.The serum creatinine level after surgery was not significantly decreased [postoperative (83.8 ±42.1) μmol/L,P =0.64].The contrast-enhanced CT or MRI of the kidneys one week postoperatively showed uniform low density in all lesion areas,which represented complete ablation and regression of the tumor.All cases were followed up regularly.One case showed relapse at the 6 th month follow-up and underwent cryoablation again.Another case,who was not regularly followed up,relapsed at 69th month after surgery.No relapse was observed in the other cases during the follow-up.Conclusions Renal cancer cryoablation is a safe,feasible and efficacious therapy for the patients who suffered from unresectable T1a renal cell carcinoma because of high surgical risk or multifocal lesions.
