objective To observe the differences between four- and single-channel recording of normal multifocal visual evoked potential (mfVEP). Methods mfVEP of 35 health individuals (70 eyes) were detected by both four- and single-channel recording with VERIS apparatus. The root mean square (RMS) value of reactive amplitude was obtained from the results of the two kinds of recording. Each stimulated patch was analyzed to compare the variational degree of each patch between the two recording methods. Responase sasymmetry coefficient (RAC) was introduced to evaluate the symmetry property between the two eyes in an individual. Results Compared with the single-channel recording,the responses of the stimulated patches of the four- channel recording were increased statistically, with most of the patches below the horizontal meridian and some of patches in the upper field, and there was distinct symmetry property between the two eyes in the same individual recorded by four-channel recording. Conclusion The four-channel recording is better than the single one and could be clinically applied and popularized.(Chin J Ocul Fundus Dis，2004，20：156-159)

Abstract: Objective To investigate the clinical results of the coronary artery bypass grafting (CABG) for coronary artery disease (CAD) patients with completed hypothyroidism. Methods Twentyone CAD patients with hypothyroidism (hypothyroidism group) operated by a single surgeon from September 2002 to June 2009 in our department were enrolled in this study. Among them, there were 6 males and 15 females. Their average age was 60.4 years old. Three patients underwent CABG with onpump beating heart; one underwent CABG with onpump arrested heart; and 17 patients underwent CABG with offpump beating heart. All patients on thyroxine replacement therapy underwent CABG after free triiodothyronine（FT3）,free thyroxin（FT4）, thyroidstimulating hormone（TSH）, total triiodothyronine（TT3） and total thyroxin（TT4） were obviously improved. At the same time, twenty CAD patients without hypothyroidism were chosen as the control group (control group). Among them, there were 6 males and 14 females with an average age of 62.1 years old. The data of thyroid gland function and clinical prognostic indicator were observed after the operation. Results For the hypothyroidism group, one patient with pericardial effusion, heart failure and low thyroxine before surgery died during the onpump operation. Among the 20 survivors who had undergone CABG with beating heart, 17 were offpump CABG patients. Followup was done for 230 months. Postoperative eject factor of the survivors were significantly higher than their preoperative eject factor (55%±21% vs. 48%±17%). Twenty patients in the control group all survived. There was no significant difference in cardiac index ［2.7±1.4 L/(min·m2) vs. 2.8±1.5 L/(min·m2), t=0.530, P=0.530］, hospital stay (12.2±4.7 d vs. 10.1±3.9 d , t=0.170, P=0.170), or mechanical ventilation time (17.6±9.1 h vs. 15.1±13.7 h, t=0.120, P=0.120) between the hypothyroidism group and the control group. Perioperative thyroxine examination showed that there was no profound impact on thyroxine by offpump CABG. Conclusions With full preparation made before operation, CABG with beating heart is comparatively safe for CAD patients with hypothyroidism. The key of the treatment is perioperative thyroxine replacement therapy. There is much risk to perform onpump CABG on patients with severe hypothyroidism.
ObjectiveTo investigate the incidence, severity and longitudinal trajectories of symptoms at various time points in the perioperative period of lung cancer patients, and to provide scientific basis for clinical staff to implement predictive nursing and dynamic management of symptom clusters. MethodsA prospective longitudinal investigation was conducted. The patients with lung cancer who underwent thoracoscopic lung surgery in four wards of the Department of Thoracic Surgery in our hospital were investigated by face-to-face and telephone follow-up before surgery, 1-2 days after surgery, on the day of discharge and 2 weeks after discharge. The investigation tool was the revised Chinese version of MD Anderson Symptom Inventory lung cancer specific module. Results A total of 192 patients with lung cancer were included in this study, including 59 males and 133 females, with an average age of (55.68±11.01) years. There were two symptom clusters (respiratory-gastrointestinal and emotional/psychological-disturbed sleep symptom clusters) before surgery, three symptom clusters (respiratory, gastrointestinal, and emotional/psychological-disturbed sleep symptom clusters) 1-2 days after surgery, three symptom clusters (pain-fatigue-emotional/psychological, respiratory, and gastrointestinal symptom clusters) on the day of discharge, and two symptom clusters (pain-fatigue-respiratory and respiratory symptom clusters) 2 weeks after discharge. The composition of symptoms was different in each time point during perioperative period. ConclusionThere are four symptom clusters in patients with lung cancer during perioperative period, which are pain-fatigue-disturbed sleep symptoms, gastrointestinal symptoms, respiratory symptoms and emotional/psychological symptoms. The symptom clusters of lung cancer patients at different time points are relatively stable, but the symptoms within the symptom clusters show dynamic changes. Medical staff should attach great importance to and continuously monitor the dynamic changes of perioperative symptom groups of lung cancer patients, do relevant education and nursing in advance, and timely adjust the management plan according to the symptom group evaluation results.
Objective To investigate the application of the fibrous envelope of tissue expanders for the tension reduction. Methods Between June 2005 and May 2011, 21 patients with facial scar were treated with skin soft tissue expansion. There were 6 males and 15 females, aged 19-33 years (mean, 24.5 years), including 19 cases of hypertrophic scar and 2 cases of atrophic scar with disease duration of 1-31 years. The scars ranged from 4 cm × 2 cm to 25 cm × 10 cm. The tissue expander was implanted under normal skin adjacent to lesions in the first stage. And the post-expanded skin flap was designed as advance flap or transpositional flap as supplement in the second stage. Fibrous envelope at the base was fixed to the periosteum or fascia nearby first, and then sutures were used between envelopes at the base and on the skin flap or to the dermis of the skin flap to keep the mouth and lower eyelid in proper position. It reduced the tension of incision and maintained the contour of the face and neck. Results After the first stage operation, 2 cases had replaced expanders because of infection and leakage. No complication of infection or hematoma occurred after the second stage operation. The patients were followed up 1-18 months (mean, 10.2 months); of them,12 were followed up more than 1 year. No secondary deformity (deviation of mouth angle, eyebrows pulling, or eyelid ectropion) occurred. The flaps had good appearance and color. The satisfactory results were achieved. Conclusion In skin soft tissue expansion of the face, the fibrous envelopes at the base could reduce the tension of the incision and prevent the deformity of the mouth and lower eyelids.
ObjectiveTo determine the effects of the management mode participated by doctors, nurses and patients on the safety of medical tubes for restlessness patients in the Neurosurgery Intensive Care Unit (NICU). MethodsA total of 133 restlessness patients treated between May 17 and November 22, 2013 were included in the study as control group, who were admitted to the NICU before application of the management mode participated by doctors, nurses and patients; another 119 restlessness patients treated between May 17 and November 22, 2014 were included in the study as research group, who were admitted to the NICU after application of the management mode participated by doctors, nurses and patients. Then we compared the accidental extubation situation between the two groups. ResultsThe accidental extubation rate of all kinds of medical tubes in the research group was lower than that in the control group, among which the extubation rate of urethral catheter (0.67% vs. 4.32%), gastric tube (2.26% vs. 10.14%), trachea cannula (1.08% vs. 7.84%), and arterial cannulation pipeline (1.12% vs. 6.93%) was significantly different between the two groups (P<0.05). ConclusionThe management mode participated by doctors, nurses and patients can effectively reduce the accidental extubation rate of medical tubes for restlessness patients, prevent the occurrence of adverse events and ensure the treatment and nursing safety in the NICU.
Objective To study the method to prepare the animal model of goat cleft palate by injection of anabasine and the effect of the malformation on the development of the facial mid-part. Methods A total of 40 female boer hybrid goats were selected, aging 8-12 months and weighing 35-55 kg. The mating day was 0 day, and at 30 days the goats assured pregnant byB type ultrasonic test were divided into 4 groups (n=10) according to intramuscular injection of 10 (experimental group 1), 15 (experimental group 2), 20 (experimental group 3) mg/ d, and no injection (control group), respectively, from the 31st to 42nd day. At pregnant 120 days and 1 month after birth, 5 fetal goats of each group were used for three dimensional reconstruction ofskull with CT scan. The maxillary bone width named as PPMM and the maxillary bone length named as APMM were measured then the hard palate general observation was performed and dry skull of goats was harvested to observe the development of maxillary. Results After injection, all pregnant lambs aborted in experimental group 3; 2 pregnant lambs aborted and 8lambs maintained pregnancy in experimental group 2. At 120 days of pregnant, no cleft palate was observed in 5 fetal lambs of experimental group 1 and control group, respectively; cleft palate and maxillary dysplasia occurred in 3 fetal lambs of experimental group 2. Among 11 newborn lambs of experimental group 1 and 8 newborn lambs of control group, no cleft palate was observed;among 7 newborn lambs of experimental group 2, cleft palate occurred in 5 with obvious maxillary dysplasia and eating difficultly. General observation of hard palate and dry skull showed obvious hypoplasia of maxillary in experimental group 2. There were significant differences in PPMM and APMM between the experimental group 2 and the control group at pregnant 120 days and 1 month after birth (P lt; 0.05). Five lambs with cleft palates of experimental group 2 survived for 1-2 months. Conclusion The animal models of goat cleft palate can established by intramuscular injection of anabasine at a dose of 15 mg/d from the 31st to 42nd day of pregnant. The facial character of the induced cleft palate goat is similar to that of human cleft palate.
Objective To investigate the current status of control preference in the surgery of lung cancer patients and explore its correlation with perceived social support. MethodsGeneral information questionnaire, control preference scale, and perceived social support scale were used to investigate the lung cancer patients who underwent surgery in Beijing Cancer Hospital from February to May 2022. Results A total of 360 survey questionnaires were distributed, and 344 valid questionnaires were collected, with an effective rate of 95.6%. The expected participation style of patients was passive in 145 patients (42.2%), while the actual participation style was more inclined to be active in 154 (44.8%) patients. The compliance rate of patients’ expected and actual participation styles in the treatment control preference process was 61.9% (Kappa=0.437, P＜0.001). The results of the analysis of influencing factors showed that the level of cultural education was an influencing factor in the actual participation of lung cancer patients in surgery control preference (P=0.029). The results of Spearman's correlation analysis showed that the actual participation of lung cancer patients in surgery control preference was positively associated with perceived social support (r=0.159, P＜0.01), and its dimensions including family support (r=0.152, P＜0.01), friend support (r=0.133, P＜0.05), and other social support (r=0.142, P＜0.01). ConclusionPatients’ expected control preference style is generally consistent with their actual control preference style, which is influenced by their cultural education and positively correlated with perceived social support. Medical and nursing staff should pay attention to the participation style of patients taking surgery decisions, develop decision aids according to different education levels, and develop individualized interventions from the perspective of improving social support initially, to improve patients’ treatment compliance and treatment care satisfaction.
