OBJECTIVE: To Study the clinical features of congenital microtia and atresia . To evaluate the methods and results of the same microtia surgery, ear canal and middle ear reconstruction. METHOD: Statistically analysis of the data of the hospitalization microtia 62 ears of 58 cases of patient in our department from January 2005 to October 2010 waw conducted. These patients with congenital ear malformations are associated with aural atresia, ossicular chain abnormalities, severe conduction Deafness. All patients received preoperative temporal bone CT examination and reconstruction, hearing examination. Operation was given in two phases, first operation aim to form a line of ear, ear canal reconstruction, ear reconstruction, the second one aim to line of ear skin graft, cranial angle of the ear reconstruction. The preoperative and postoperative data were retrospectively analyzed. RESULT: The auricle plus external auditory canal, middle ear reconstruction came out with a good shape of the ear and the ear canal in close proximity to the normal population. Most patients' hearing were improved after surgery. CONCLUSION Surgeries of patients with congenital ear malformations and aural atresia should be carefully designed according to the three-dimensional reconstruction of multislice spiral CT reconstruction, which can provide information about surgery approach and middle ear abnormality. The whole ear shape and hearing ear after reconstruction are improved after the surgery.

Objective To investigate the application and the effects of individualized hollow resin plugs in the prevention of external auditory canal stenosis after canaloplasty of external auditory meatus for microtia patients . Methods The clinical data of 65 patients (68 ears) with microtia and aural atresia hospitalized in our department from January ,2006 to December ,2015 were summarized .Otoplasty of external ears and canaloplasty of external auditory meatus were operated on all patients under general anesthesia .Thigh flap transplantation was lined in the bony canal .One month later ,individualized hollow resin plugs were made and worn for 6 to 12 months ,and fol-lowed up for 1～2 years .Results The shapes of the reconstructed auricles were satisfactory .Sixty-four ears with wide external auditory canal openings were recorded in 68 ears .Preoperative hearing was 70 .45 ± 5 .5 dB HL ,and postoperative hearing was 55 .55 ± 5 .2 dB HL .Their hearing was not affected .External auditory canal restenosis occurred in 4 ears .Conclusion The individualized hollow resin plugs do not affect the hearing in use ,and can effec-tively prevent the restenosis of the external auditory canal after microtia reconstruction .

Objective:To evaluate the effect of different clear fluid fasting duration on the fluid responsiveness after anesthesia induction in pediatric patients with congenital heart disease.Methods:One hundred pediatric patients with congenital heart disease who underwent elective atrial septal defect or ventricular septal defect correction surgery at Shanghai Children′s Medical Center affiliated to Shanghai Jiao Tong University School of Medicine from December 2023 to February 2024 were selected. They were of either sex, aged 6 months to 3 yr, with a body mass index of 13-19 kg/m 2, and classified as American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ. Patients who adhered to the prescribed preoperative clear fluid fasting regimen, with a fasting duration of 6 h or longer before surgery, were included in the long fasting (LF) group, while those who were prescribed multi-dimensional nutritional solution until 2 h before surgery with a solid fasting duration≥6 h were considered for inclusion in the short fasting (SF) group. The diastolic blood pressure (DBP) was recorded immediately before and after liver compression test at pre-induction of anesthesia and immediately before and after liver compression test at post-induction of anesthesia, and the changes in DBP before and after the liver compression test (ΔDBP) were calculated. Positive fluid responsiveness was defined as an increase in ΔDBP ≥ 6.25%. The positive rate of fluid responsiveness before and after anesthesia induction was calculated. Results:Sixty-four patients were finally included, and both LF and SF groups included 32 cases. Before the induction of anesthesia, the positive rate of fluid responsiveness induced by liver compression was 28.1% in LF group and 18.8% in SF group, and the difference was not statistically significant ( P>0.05). However, after the induction of anesthesia, the positive rate of fluid responsiveness induced by liver compression was 56.3% in LF group and 28.0% in SF group, with a statistically significant difference observed ( P<0.05). Compared with the baseline before anesthesia induction, the positive rate of fluid responsiveness was significantly increased in LF group( P<0.05), and no significant change was found in the positive rate of fluid responsiveness in SF group ( P>0.05). Conclusions:The prolonged clear fluid fasting may lead to an increase in the positive rate of fluid responsiveness following anesthesia induction in pediatric patients with congenital heart disease, presenting as a state of hypovolemia.

ObjectiveTo investigate the impact of yang deficiency syndrome on the progression to end-point events of diabetic kidney disease （DKD）. MethodsA retrospective study among patients with stage Ⅳ DKD admitted to Dongzhimen Hospital of Beijing University of Chinese Medicine from September 1st， 2016 to September 30th， 2021 was conducted. Data on the patients' general information， clinical indicators including duration of diabetes， duration of proteinuria， history of smoking and drinking， hemoglobin （HGB）， fasting blood glucose （FBG）， albumin （ALB）， serum creatinine （Scr）， urea nitrogen （BUN）， uric acid （UA）， cholesterol （TC） ， triglycerides （TG）， low-density lipoprotein （LDL）， 24-hour urine protein quantification （24h-UTP） and estimated glomerular filtration rate （eGFR）， and TCM syndromes including symptoms， tongue and pulse， and syndrome scores were collected. The patients were divided into exposure group （yang-deficiency group） and non-exposure group （non-yang-deficiency group）. The general information， clinical indicators and incidence rates of end-point events were compared， and the impact of yang deficiency syndrome on the end-point events of stage Ⅳ DKD was analyzed. Survival analysis was performed using Kaplan-Meier method， and multivariate Cox proportional risk models were used to identify independent predictors of end-point events. ResultsA total of 160 patients with stage Ⅳ DKD were included in the study， including 43 cases of yang deficiency syndrome and 117 cases of non-yang deficiency syndrome. Compared to those in the non-yang deficiency group， the waist circumference， BUN and the incidence of end-point events in the yang deficiency group were significantly higher （P＜0.05 or P＜0.01）. Spearman correlation analysis showed that yang deficiency syndrome was positively correlated with incidence of end-point events of stage Ⅳ DKD （r = 0.167， P = 0.035）. Furthermore， 24h-UTP and BUN levels were also positively correlated with end-point events in stage Ⅳ DKD patients （P＜0.01）， while ALB and HGB levels were negatively correlated （P＜0.01）. Kaplan-Meier survival curves showed that yang deficiency syndrome was associated with an increased risk of end-point events （Log Rank P = 0.011）. Moreover， 24h-UTP levels ≥3500 mg， BUN level ≥8 mmol/L， ALB level ＜30 g and HGB level ＜11 g were all associated with the increase of the risk of end-point events （P＜0.05 or P＜0.01）. Multivariate Cox regression analysis showed that yang deficiency syndrome was an independent risk factor for patients with stage Ⅳ DKD to progress into end-point events （HR = 2.36， 1.32 to 4.21； P = 0.004）， as well as 24h-UTP ≥ 3500 mg， BUN ≥ 8 mmol/L， HGB＜11 g and ALB＜30 g （P＜0.05 or P＜0.01）. ConclusionsFor stage Ⅳ DKD， patients with yang deficiency syndrome are more likely to have end-point events， which is an independent risk factor for the progression into end-point events.

Objective: To explore the utility of pharyngeal pH monitoring which positive standard is Ryan index in diagnosis of laryngopharyngeal reflux disease. Methods: In a retrospective study, clinical data of 590 patients who had symptoms laryngopharyngeal reflux disease from February 2016 to March 2017 were analyzed. All patients were received electronic laryngoscopy, assessment of reflux symptom index(RSI) and reflux finding score(RFS), and pharyngeal pH monitoring. SPSS 19.0 software was used to analyze the date. Results: There were 94 patients whose Ryan index were positive(15.93%). Among the 94 patients, 70 were positive during upright, 12 during supine and 12 during both upright and supine. There were 40 patients(6.78%)with pH decline events related to symptoms, while those Ryan index were normal. There were 536(90.85%), 417(70.68%), 233(39.49%) and 117(19.83%) patients with pH<6.5, pH<6.0, pH<5.5 and pH<5.0 events respectively. The positive rate of RSI, RFS, RSI and RFS, RSI or RFS were 44.24%, 16.78%, 7.12%, 53.90% respectively. The RFS score in Ryan index positive group was higher than that in Ryan index negative group[(8.2±2.4) vs (4.0±2.9), u=5.424, P<0.05], while the RSI score in Ryan index positive group was not statistically different from that in Ryan index negative group[(11.3±6.2) vs (12.7±5.8), t=1.247, P=0.167]. Conclusions Pharyngeal pH monitoring is an objective and non-invasive method which can reflect laryngopharyngeal reflux directly. However, with the Ryan index as a criterion for the diagnosis of laryngopharyngeal reflux disease, partial patients may be missed. Further studies are needed to obtain more accurate and objective laryngopharyngeal pH statistical index for diagnosis of laryngopharyngeal reflux disease.
