OBJECTIVETo explore the anesthetic effect of preemptive analgesia of frequency acupoint electrical stimulation on painless-induced abortion as well as its effect on anesthetics dosage.

METHODSNinety cases of early pregnancy who selected painless-induced abortion were randomly divided into two groups, 45 cases in each group. Frequency acupoint electrical stimulation at Ciliao (BL 32) and Shenshu (BL 23), disperse-densewave, 2 Hz/100 Hz in frequency for 15 to 20 min, was applied in the group A, which was followed by intravenous anesthesia of propofol. The intravenous anesthesia of propofol was applied in the group B. The blood pressure (BP), heart rate (HR) and SpO2 before, during and after surgery, anesthetic effect and dosage, waking time and adverse events were observed in the two groups.

RESULTSThe BP and HR during and after the surgery in the group A were not statistically different from those before the surgery (all P > 0.05). The BP was reduced and HR was slowed down during the surgery in the group B, which was significantly different from those before the surgery as well as those in the group A (all P < 0.05). The dosage of propofol was (114. 3-+6. 1) mg in the group A. obviously less than (193.2 +/- 8.9) mg in the group B (P < 0.05). The waking time was (5.6 +/- 1.2) min in the group A, obviously less than (10.1 +/- 3.9) min in the group B (P < 0.05). As for anesthetic effect, the incidence of Grade I in the group A was more than the group B (P < 0.05). The adverse events, including nausea, vomiting and contractions pain in the group A were evidently less than those in the group B (all P < 0.05).

CONCLUSIONThe preemptive analgesia of frequency acupoint electrical stimulation could significantly improve anesthetic effect of painless-induced abortion, reduce dosage of anesthetics, shorten waking time of surgery and guarantee the safety of surgery.

OBJECTIVE To investigate the rescue and treatment of critical children with tracheobronchial foreign body. METHODS From June 2011 to June 2015,there were 2489 children with tracheobronchial foreign bodies treated in Children's Hospital of HeBei Province, among which 11critical children who were rescued as soon as they came to the hospital. The clinical data of the 11critical children were analyzed. RESULTS All the 11 critical cases endured dyspnea of third degree or more severe and presented severe hypoxia, in which 2 children had been performed tracheal intubation before they came to the hospital and 1 child even showed the symptom of respiratory and cardiac arrest. Among these critical cases, the foreign body was removed directly without anesthesia in 1 child. The other 2 children with severe pneumothorax, mediastinal emphysema and subcutaneous emphysema in neck and chest area were treated by excision and drainage of emphysema firstly, and then the foreign bodies were extracted through bronchoscope after general anesthesia. The another 8 children were performed operations of extraction of bronchial foreign body and then the foreign bodies were taken out. All the 11 critical children were rescued successfully and no death cases happened. CONCLUSION Rapid diagnosis and rapid removal of foreign bodies is the key to save the lives of critical children with tracheobronchial foreign bodies.

Objective To investigate the change of peripheral blooe T cell subsets,NK cells ane serum soluble interleukin-2 receptor(sIL-2R)concentration in patients with gastric cancer before ane after surgery,ane to uneerstane immune function status ane changes of perioperative gastric cancer patients. Methods One huneree ane thirty-five perioperative gastric cancer patients were selectee as our subjects who hospitalizee from May 2009 to May 2011 in Tumor Hospital of Shanxi Province,ane they were servee as treatment group,while 50 healthy subjects were selectee as controls. The number of CD3 + ,CD4 + ,CD8 + T cells,rate of CD4 + / CD8 +ane the NK cell ratio in blooe cells were eetectee by flow cytometry. ELIAS was appliee to measure serum sIL-2R concentration. Observee the above ineexes of control group at the same perioe,ane comparee the ineexes before operation of 1 e of the treatment group. Results The rate of NK cells,CD3 + T cells ane CD4 + / CD8 +ratio in patients at pre-operation were(10. 11 ± 3. 64)% ,(55. 60 ± 9. 61)% ,(30. 22 ± 6. 17)% ,1. 14 ± 0. 35,respectively,lower than that of control group(( 28. 39 ± 5. 81 )% ,( 68. 65 ± 7. 39 )% ,( 47. 87 ± 4. 85)% ,1. 82 ± 0. 24 respectively;t = - 5. 9,8. 6,8. 2,12. 7;P < 0. 01). CD8 + T positive rate of cells increasee from(27. 05 ± 7. 86)% to(34. 26 ± 6. 23)%(t = - 6. 5,P < 0. 01). At 14th eay after surgery,the cell immune function of the patients recoveree graeually,ane there were statistically significant eifferences in the above ineexes comparee with pre-operation(P < 0. 05). The eramatic changes were seen among patients with the late Gastric cancer TNM staging. Comparee with patients with stage Ⅳ,all above ineex were significant eifferent from that of patients with stageⅠ,Ⅱ(P < 0. 05),ane no significant eifferences was seen in patients with stageⅢ(P > 0. 05). The concentration of serum sIL-2R in patients with gastric cancer before operation was(575. 71 ± 34. 77)U/ L,higher than that of healthy persons((428. 26 ± 21. 77)U/ L,t = - 7. 9,P < 0. 01),ane serum sIL-2R levels in patients with stage Ⅲ,Ⅳ was lower than that of patients with stage Ⅰ,Ⅱ patients with low(P< 0. 05). Conclusion The immune function of patients with gastric carcinoma is relatee to tumor loae size ane eifferent pathological staging. The ineex of the ratio of NK cells ane T lymphocyte subsets,serum sIL-2R levels can be servee as ineicators for monitoring perioperative evaluation of prognosis of gastric cancer.

Objective To investigate the therapeutic effects of electroacupuncture (EA) on post stroke depres- sion (PSD) after lacunar infarction (LI).Methods Seventy-five PSD patients with lacular infarction were recruited and randomly divided into a control group and an EA group.All patients were treated with Fluoxetine,in addition to EA treat- ment in the EA group.Then all patients were evaluated using the Hamilton Depression Scale (HAMD),the Chinese stroke scale (CSS) and the Barthel Index (BI).The evaluations were carried out at 0,14 and 28 days.Results Depression symptoms (DSs) in the EA group were improved by day 14 of the treatment,and their HAMD scores had decreased.DSs in both groups had improved significantly by day 28,and the HAMD scores in the EA group were then significantly lower than those in the control group.Improvements in neurological impairment and in the activities of daily living were observed earlier in the EA group.Conclusion The combination of EA and Fluoxetine is helpful for PSD with complex patho- genesis and clinical symptoms.Therapeutic effects are enhanced and side effects are reduced.

Background This meta-analysis evaluated the effect of noninvasive,positive pressure ventilation on severe,stable chronic obstructive pulmonary disease (COPD).Methods PUBMED,CNKI,Wanfang,EMBASE and the Cochrane trials databases were searched.Randomized controlled trials of patients with severe,stable COPD and receiving noninvasive positive pressure ventilation,compared with sham ventilation or no ventilation,were reviewed.The mortality,physiological and health related parameters were pooled to yield odds ratio (OR),weighted mean differences or standardized mean differences (SMD),with 95％ confidence interval (C/).Results Eight parallel and three crossover randomized controlled trials met the inclusion criteria.Pooled analysis for parallel,randomized controlled trials showed noninvasive positive pressure ventilation:(1) Did not affect the 12-or 24-month mortality (OR 0.82,95％ C/:0.48 to 1.41); (2) Improved the arterial carbon dioxide tension (SMD-0.88,95％C/:-1.43 to-0.34); (3) Did not improve forced expiratory volume in one second (SMD 0.20,95％ C/:-0.06 to 0.46),maximal inspiratory pressure (SMD 0.01,95％ C/:-0.28 to 0.29) or 6-minute walk distance (SMD 0.17,95％ C/:-0.16 to 0.50); (4) Subgroup analysis showed noninvasive positive pressure ventilation improved the arterial carbon dioxide tension in hypercapnic patients.Pooled analysis for crossover randomized controlled trials did not show improvement in arterial blood gas or forced expiratory volume in one second with noninvasive positive pressure ventilation.Conclusions Noninvasive positive pressure ventilation improves the arterial carbon dioxide tension but does not improve the mortality,pulmonary function,or exercise tolerance and should be cautiously used in severe stable chronic obstructive pulmonary disease.

Objective This study is to investigate the set-up accuracy of thermoplastic mask used for immobilization of nasopharyngeal carcinoma (NPC) patients being treated by Intensity Modulated Radia- tion Therapy (IMRT).Methods Nineteen patients with early stage nasopharyngeal carcinoma (T1- T2N0M0),treated by fractionated intensity-modulated radiation therapy,underwent repeated CTs during their 6-week treatment course.We evaluated their anatomic landmark coordinates in a total of 85 repeated CT data sets and respective x,y and z shifts relative to their position in the 19 treatment-planning reference CTs.Results The translation in x,y,and z-axes with their mean value derived from both positive and negative set-up errors was-0.84 mm(x-axis),+0.65 mm(y-axis) and +0.01 mm(z-axis).Mean target isocenter translation was (0.89?0.69) mm,(0.82?0.79) mm,(0.95?1.24) mm in x,y and z-direc- tions,respectively.The mean total magnitude vector and 95% CI of isocenter motion were 1.87 mm and 4.65 mm.The data measured over the 6-week fractionated course of treatment revealed a slight deterioration of isocenter accuracy.The 95% CI,considered by us to be a valuable parameter for characterizing the sys- tem,of 4.17 mm for measurement within the first 3 weeks increased to 5.12 mm in the last 3 weeks of treat- ment.Conclusions The sequential CT scanning is a pronounced valuable method of evaluating the quality of departmental specific patient positioning procedures.The thermoplastic mask is eyed as well suited tool for immobilization and repositioning of NPC patients receiving intensity-modulated radiation therapy.
