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)

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.
ObjectiveTo evaluate the degree of psychological pain for cancer patients undergoing surgical treatment and analyze the contributory factors to provide the theoretical basis for psychological intervention for cancer patients with surgical treatment.MethodsThe clinical data of 455 cancer patients who received surgeries in our hospital from November 2020 to January 2021 were retrospectively analyzed, including 225 males and 230 females aged 53.80±13.50 years. By applying the method of convenient sampling, a cross-sectional survey was carried out by gathering the general information of the patients and evaluating their mental condition with the distress thermometer. The contributory factors were discussed by logistic regression analysis.ResultsThe score for the psychological pain of the patients was 4.11±2.49 points. The main factors contributing to the psychological pain were physical problems, emotional problems and family matters. The logistic regression analysis showed that the main factors related to the degree of psychological pain were cancer types (P=0.023), religious belief (P=0.046), number of niduses (P=0.016), respiratory status (P=0.004), medical expense (P=0.007), grief (P=0.001) and anxiety (P=0.040).ConclusionNearly half of the patients have been subjected to apparent psychological pain, and emotion and physical problems are the main factors. It is crucial to pay attention to the patients’ mental problems, seek convenient tools for psychological evaluation, and take actions to deal with the psychological problems and physical symptoms.
Objective To study the disinfection effect of hand disinfectants containing alcohol after heating, and the comfortable feeling of using warm disinfectants among the medical staff in operation rooms. Methods Between November 2016 and January 2017, we analyzed the disinfection effect of two alcohol-containing hand disinfectants after heating in operation rooms through on-the-spot disinfection and inspection. Questionnaire was used to investigate the comfortable feeling of using warm hand disinfectants. Results After standing for 7 days at a temperature of 37℃, the major content of the two disinfectants decreased by less than 10%. Three minutes of disinfection by using the two kinds of disinfectants had an average natural-bacteria killing logarithm higher than 1.00, and they both had a qualified disinfection effect. Moreover, 96.7% of the medical personnel believed that warm disinfection products were more comfortable. Conclusion After heating, the two kinds of alcohol-containing hand disinfectants are effective in hand disinfection and more comfortable to use, which can improve hand hygiene compliance in surgical staff.
Objective To investigate the myocardial protective effects of Del Nido cardioplegia and analyze its advantages in adult cardiac surgery. Methods We retrospectively analyzed the clinical data of 96 adult patients undergoing cardiac valve surgery who received Del Nido cardioplegia (a DNC group) from June 2016 to January 2017 in our hospital. There were 44 males and 52 females with a mean age of 51.36±13.31 years. Meanwhile 96 patients who received conventional cardioplegia were recruited as a control group (a CTC group) and there were 53 males and 43 females with a mean age of 52.91±10.95 years. Cross-clamping time, cardiopulmonary bypass (CPB) time, total volume of and transfusion frequency of cardioplegia, the rate of spontaneous defibrillation, red blood cell transfusion and vasoactive-inotropic score at postoperative 24 hours (VIS 24) were recorded. Results No significant difference was found in age, body weight, ejection fraction, hematokrit, CPB time and cross-clamping time between the DNC group and CTC group. There was no significant difference in the rate of spontaneous defibrillation, VIS 24, cardiac enzymes and cardiactroponin I and length of ICU stay between the two groups. The total volume and transfusion frequency of cardioplegia, perioperative blood transfusion were lower in the DNC group. There was no new atrial fibrillation or in-hospital death in the two groups. Conclusion Del Nido is a good myocardial protection solution in adult cardiac valve surgery, and requires less static preload volume and reduceshemodilution and perioperative blood transfusion.
Objective To study the mid-facial development characteristics of the goats with cleft palate after in-utero surgical repair at different stages. Methods Twenty-four Boer hybrid female goats were selected, aged from 8 to 12 months and weighing from 35 to 55 kg. The mating day was designated for 0 day. At 30 days, pregnant was confirmed by B-ultrasound test, and the goats were divided into 5 groups (experimental groups 1, 2, 3, 4, and normal control group). Twenty pregnant goats of 4 experimental groups (n=5) were injected DL-anabasine (15 mg/day) from 31 to 42 days to establish cleft palate model of fetal lamb, 4 pregnant goats of normal control group used as controls without injection. At pregnant 65, 90, and 120 days, cleft palate was repaired in the uterus in experimental groups 1, 2, and 3, while cleft palate was not repaired in experimental group 4. After 1 month of birth, the maxillary bone width (posterior premolar morphological measurement, PPMM) and the maxillary bone length (anterior premolar morphological measurement, APMM) were measured with CT scanning. The dry skull of goats were harvested for gross observation. Results There was no significant difference in PPMM and APMM between experimental group 1 and the normal control group (P gt; 0.05), but there were significant differences between experimental groups 1 and 4 (P lt; 0.05) at 1 month after birth. Significant differences were oberved in PPMM and APMM between experimental group 2 and normal control group, experimental group 4 (P lt; 0.05). There were significant differences in PPMM between experimental group 3 and normal control group, experimental group 4 (P lt; 0.05), in APMM between experimental group 3 and normal control group (P lt; 0.05). Five goats with cleft palate in experimental group 4 died at 1-2 months after birth. Conclusion At pregnant 65 days, in-utero surgical repair of cleft palate has less influences on mid-facial development. The earlier repair is performed, the higher risk of miscarriage was.
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.
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.
