OBJECTIVETo evaluate the diagnostic value of micro-movement sensitive mattress sleep monitoring system (MSMSMS) in children with obstructive sleep apnea hypopnea syndrome.
METHODSSixty-five children with the complaint of sleep disorder were collected and detected by polysomnography and micro-sensitive mattress sleep monitoring system overnight at least seven hours. The date from two instruments were analyzed by computer automatically and then modified by two professional staff double-blind separately. The data about the diagnosis of sleep breath disorder and other sleep physiology information were compared between the two groups.
RESULTSSixty-one cases finished the study finally. The mean age of these children was (7.0 ± 2.7) and the youngest was 3 years old, maximum was 13 years old, male children 46 cases, female patients 15 cases, body mass index (BMI) median [25 quantile; 75 quantile] 16.00 [14.80;17.5]kg/m2. Mean PSG measured apnea hypopnea index (AHI) was 4.50 [2.30;10.15] times/h, and mean MSMSMS AHI was 3.63 [2.56; 6.43] times/h. There was a significant correlation between PSG AHI and AHI by MSMSMS (r = 0.935, P < 0.01). A Bland-Altamplot of PSG AHI and MSMSMS AHI was also used to assess the accuracy of MSMSMS. 95. 1% of the data was fallen in the 95% consistency areas. For AHI--5 times/h and nighttime minimum oxygen < 91% or obstructive apnea index( OAT) > 1 time/h and nighttime minimum oxygen saturation < 91 % as threshold value, the MSMSMS diagnosing sensitivity and specificity were 82.9% and 92.3%. The misdiagnosis rate and missed diagnosis rate were 7.7% and 17.1%.
CONCLUSIONSThe MSMSMS offer a simple and comfortable method to monitor children's sleep. It improves the compliance in the process of sleep monitoring. Besides, as a diagnostic tool in the diagnosis of OSAHS on children has a high credibility in AHI.

Objective To evaluate influence of patient-controlled intravenous analgesia (PCIA) and patient-controlled epidural analgesia (PCEA) on expressions of serum inflammatory cytokines in elderly patients with hemi or whole hip replacement using cemented artificial joint. Methods Elderly patients undergoing hip replacement were selected and were divided into PCIA group and PCEA group. VAS scores were calculated at 12 h postoperatively. Patients whose VAS scores were not more than 2 at postoperative 12h were included. 30 cases in each group were finally included. Fifteen cases were randomly chosen in each group and underwent sample blood drawing for assays. Expressions of serum inflammatory cytokines were detected by ELISA , RT-PCR and Western-blot. Results Gene and protein expressions of TNF-a as well as IL-6 in group PCEA were lower and expression of IL-10 was higher than that in group PCIA. Serum level of TGb-β was higher in group PCEA detected by ELISA. There was no significant difference in expression of IL-8 between groups. Conclusions PCEA may better promote expressions of anti-inflammatory cytokines and inhibit expressions of proinflammatory cytokines. PCEA is superior in maintenance of inflammatory cytokine balance.

Objective In order to extrapolate the respiratory dysfunction of patients in early stage of acute organophosphorus pesticide poisoning (AOPP),transpulmonary thermodilution technique was used in swine models of severe acute dichlorvos poisoning (SADP) to evaluate respiratory function.Methods Twenty healthy female swine were randomly divided into dichlorvos ( n =7 ),atropine ( n =7 ) and control (n =6) groups.In the dichlorvos group,the swine were administered with 80% emulsified dichlorvos (100mg/kg) via the gastric tube toinduce SADP.In the atropine group,swinewere administered with dichlorvos,and 0.5h later,atropine was injected to obtain and maintain atropinization.The swine of control group were administered with saline solution instead.Arterial and venous blood samples were collected 0,0.5,1,2,4 and 6 hours after modeling for blood gas analysis and detecting acetylcholinesterase levels.Both extravascular lung water index (EVLWI) and pulmonary vascular permeability index ( PVPI ) were measured by using PiCCO (pulse indicator continuous cardiac output ). At the termination of the experiment,the animals were sacrificed and the lung wet/dry weight ratio was determined and histopathological changes of lung tissue were also observed under microscope.Results In the dichlorvos group,EVLWI and PVPI were substantially increased from 0.5 h to 6 h after modeling but PaO2/FiO2 decreased from 0-6 h after modeling.In the atropine group,EVLWI and PVPI increased initially,but then they decreased 1 h afterwards and PaO2/FiO2 was also gradually decreased from 0-1 h.In both dichlorvos group and atropine group,the EVLWI was negatively correlated with PO2/FiO2 and positively correlated with PVPI.Compared with the control group,the lung wet/dry weight ratio increased markedly in the dichlorvos group and mildly increased in the atropine group.Meanwhile,the histopathological changes of lung tissue were obvious in the dichlorvos group and mild in the atropine group.Conclusions SADP swine experienced substantial changes in respiratory function. EVLWI was a reliable and valuable indicator for evaluating respiratory function in the early stage of AOPP.

OBJECTIVE This study was conducted to analyze the underlying bacterial pathogens of the tonsils and adenoids in children with sleep-disordered breathing(SDB).METHODS The core tissue from the tonsils and/or adenoids of 163 SDB children was cultured aerobically. Of the 163 cases, 120 children underwent adenoidectomy and tonsillectomy simultaneously(A+T), 39 children underwent adenoidectomy(A) and 4 tonsillectom(T) only. 124 children who underwent tonsillectomy were subdivided into two groups based on history(with or without a history of recurrent tonsillitis). 71 children with the history were enrolled in the 'recurrent tonsillitis group' and 53 children without the history were enrolled in 'non- recurrent tonsillitis group'.RESULTS Of the total 120 cases who underwent A+T, 114(95.00%) cases had same distribution of bacteria detected in both sides in the same patient. Besides this, 17 cases in whom mixed organisms were identified in both sites shared common pathogen. No significant difference in the detection rates of staphylococcus aureus and haemophilus influenzae were found when we compared seasons(Tonsil:χ2=8.538,P=0.201; Adenoid:χ2=5.427, P=0.490). No significant difference in the type and detection rate of essential bacteria was found when we compared between recurrent tonsillitis group and 'non-recurrent tonsillitis group' (χ2=3.028,P=0.387).CONCLUSION The bacterial isolates from the tonsils and adenoids are virtually identical in type and detection rate in the same SDB patient. The bacterial distribution of the tonsillar and adenoidal core is unaffected by the seasonal variation and history of recurrent tonsillitis.

Objective To explore surgical approach for internal mammary node biopsy in patients with breast cancer. Methods Modified radical mastectomy and incised intercostal muscles for internal mammary node biopsy was performed on 113 patients. The distance from the internal mammary artery to the lateral sternal border, and the intercostal distance between the two costal cartilage were measured. Anatomical location and maximal diameter of the excised nodes were recorded. Results The internal mammary artery runs through intercostal space along the lateral sternal border. The distance from the internal mammary artery to the lateral sternal border was (10. 9?4. 5) mm, (11.6?2.9) mm, (9.6?3.6) mm and (4.5?3.5) mm in the first, second, third and fourth intercostal space, respectively. The distance between the two costal cartilage was (14. 2?4. 1) mm, (16. 2?4. 2) mm, (13. 9?4. 3) mm and (9.9?3. 6) mm in the first,second, third and fourth intercostal space, respectively. Two hundred and seventy-nine internal mammary nodes were excised from 113 patients. The anatomical location of the internal mammary nodes which embedded in the fatty tissue surrounding internal mammary artery were 41. 2% at the medial side, 51. 6% at the lateral side and 7. 2% in an anterior plane to the internal mammary artery. Metastases in the internal mammary node were detected in 26 patients. The lymph nodes metastasis were detected only in the internal mammary nodes in 5 cases. Conclusion Internal mammary node biopsy via intercostal space is a feasible, minimally traumatic, low-risk procedure.

Objective To investigate the median effective dose (ED50) of cisatracurium priming accelerating the onset of neuromuscular block in patients of different genders. Methods Ninety ASA Ⅰ or Ⅱ patients aged 18-55 yr undergoing elective abdominal operation under general anesthesia were divided into 2 groups ( n = 45 each): male group (group M) and female group (group F). Neuromuscular block was monitored with accelerograph F (TOF-Watch SX). A single twitch stimulation of ulnar nerve was used to monitor neuromuscular function.Anesthesia was induced with midazolam 0.04 mg/kg and fentanyl 1 μg/kg. Accelerograph F was opened after the patients lost consciousness. The priming dose of cisatracurium was injected intravenously, then fentanyl 5 μg/kg and propofol 2 mg/kg were injected intravenously 3 min later and the left dose of cisatracurium for intubation was injected intravenously 4 min later. Tracheal intubation was performed when the ratio of the single twitch stimulation value to control value (T/Tc). decreased to 10%. Anesthesia was maintained with iv infusion of propofol and remifentanil and inhalation of isoflurane. The priming dose of cisatracurium was determined by up-and-down sequential trial. The initial priming dose was set at 5 μg/kg. The ratio of two successive doses was 1.2. T/Tc, time to 90% block, onset time, maximal neuromuscular block and clinical duration were recorded 4 min after the administration of the priming dose. The ED50 and 95% confidence interval (CI) of cisatracurium priming required to accelerate the onset were caculated. Results Time to 90% block was significantly longer-in group M than in group F (P <0.05). No significant difference was found in the other parameters among the groups. The ED50 and 95% CI of cisatracurium priming required to accelerate the onset were 21.36 μg/kg (95% CI 20.52-22.23 μg/kg)in group M and 14.53 μg/kg (95% CI 13.77-15.33 μg/kg) in group F. The ED50 was significantly higher in group M than in group F ( P < 0.05). Conclusion The ED50 of cisatracurium priming accelerating thd onset is 21.36 and 14.53 μg/kg in male and female respectively and it is significantly higher in male than in female.
