Objective To retrospectively compare the clinical results of locking plate of proximal humerus (LPPH) and traditional AO plates in treatment of proximal humerus fractures in aged osteoporotic population. Methods From July 2002 to May 2005, 37 old osteoporotic patients with humerus fractures were treated with LPPH and traditional AO plates respectively in our department. The results were compared retrospectively. Results Follow-ups were conducted six weeks, 12 weeks and one year postoperatively to assess shoulder scores, bone healing and necrosis of humerus head. Comparison showed that the results for LPPH group were statistically better than those for traditional AO plate group in rate of implant loosening and SPADI (shoulder pain and disability index) scores. Conclusion LPPH has an obvious advantage over traditional AO plate in treatment of proximal humerus fractures in aged osteoporotic people.

Spasmodic dysphonia is a primary task specific focal dystonia affecting the laryngeal muscle during speech. Adductor spasmodic dysphonia (ADSD) affects close to 90% of spasmodic dysphonia patients is characterized by voice breaks during vowels during speech due to intermittent hyperadduction of the vocal folds. Abcuctor spasmodic dysphonia (ABSD) is relatively rare and involves intermittent voiceless voice breaks due to prolonged voiceless consonants before initiation of the following vowels. Treatment for spasmodic dysphonia has been aimed at denervation or adjustment of the larynx to prevent the uncontrolled spasms in the laryngeal muscles from interfering with voice production. As a result there is a risk-benefit ratio in that the denervation must be adequate to reduce the detection of symptoms whereas at the same time not producing aphonia, breathiness and swallowing difficulties. This article summarizes the pathogenesis, diagnosis and treatment of the spasmodic dysphonia.

Objective To study the variability of oxygen saturation in intestinal tissue of preterm infants during erythrocyte infusion .Method Preterm infants aged over 5 days, hospitalized in our NICU from March 2016 to August 2016 were selected by computer random number generator . Near-infrared spectroscopy was applied to monitor splanchnic tissue oxygen saturation ( SrSO2 ) and cerebral tissue oxygen saturation(CrSO2)during erythrocyte transfusion.The duration of transfusion was 4 hours.The mean value and range of SrSO2 and CrSO2 during transfusion were analyzed.To analysis the average and variable range of SrSO2 and CrSO2 and to illuminate the correlation with post-conceptional age. Result A total of 34 premature infants were collected.The average of SrSO2 was (0.56 ±0.06) and the average of CrSO2 was (0.62 ±0.02) throughout transfusion, There was a significantly greater change in SrSO2 than in CrSO2 during the transfusion period (0.35 ±0.14 vs.0.18 ±0.09) (P<0.05).The changing range of CrSO2 was smaller as the post-conceptional age increased , and was significant different statistically ( P=0.006). While there was little change in the range of SrSO 2 (P=0.191).Conclusion The of SrSO2 change was more significant than CrSO 2 in preterm infants during erythrocyte transfusion , which may cause ischemia-reperfusion injury to the intestinal tissue .It should be more cautious to avoid transfusion-related necrotizing enterocolitis.

Objective:To investigate the prognostic value of texture analysis of MRI diffusion weighted imaging (DWI) for neonatal hypoglycemic encephalopathy (HE).Methods:The clinical data and MRI data of 119 patients with neonatal HE admitted to Children′s Hospital of Nanjing Medical University from July 2013 to September 2020 were retrospectively analyzed. The children were followed up to 7—8 months and scored by Bayley scales of infant and toddler development. According to the overall development index, the children were divided into three groups: normal group (≥85, group A, n=42), mild developmental retardation group (70－84, group B, n=46) and developmental retardation group (≤69, group C, n= 31). The whole brain region (except sulcus and cisterna) was delineated as region of interest (ROI) by LIFEx 3.4 software in MRI apparent diffusion coefficient images. A total of 37 parameters were calculated automatically by the software, The clinical data, including gender, gestational age, age at MRI scan, birth weight, mode of delivery, history of asphyxia at birth, maternal preeclampsia or diabetes, minimum blood glucose, duration of hypoglycemia, neonatal behavioral neurological assessment (NBNA), presence or absence of polycythemia); the texture parameters, including histogram, volume, gray level co-occurrence matrix (GLCM), gray level run length matrix (GLRLM), neighborhood gray tone difference matrix (NGTDM), gray level size zone matrix (GLSZM), in the three groups were analyzed; and the diagnostic efficacy of clinical parameters and texture parameters was analyzed. Multivariate Logistic regression was used to analyze statistically significant clinical parameters and texture parameters, and receiver operating characteristic curve (ROC) was used to evaluate the prognostic efficacy of these parameter for neonatal HE. Results:There were no significant differences in gender, gestational age, age at MRI scan, delivery mode and blood glucose minimum among the three groups ( P>0.05). There were significant differences in birth weight [(3 150±130)g, (3 020±220)g, (2 880±140)g, F=-0.31, P=0.015], history of suffocation (10 cases, 18 cases, 20 cases, P=0.001), history of maternal diabetes or preeclampsia (14 cases, 29 cases, 21 cases, P=0.002), blood glucose duration [(5.0±0.2)d, (8.0±0.4)d, (14.0±1.7)d, F=-3.09, P=0.030] and NBNA scores (32.0±3.2, 28.0±2.6, 22.0±1.9, F=-4.21, P=0.010) among three groups. There were significant differences in kurtosis and entropy of histogram (2.57±1.12, 3.66±0.98, 4.23±0.37, F=3.54, P=0.010;5.89±1.09, 7.67±2.12, 8.92±1.62, F=-4.42, P=0.020); energy, contrast and dissimilarity of GLCM (0.48±0.01, 0.36±0.02, 0.23±0.01, F=-3.12, P=0.001;2 419±21, 3 354±31, 4 313±26, F=-4.16, P=0.020;126±14, 153±23, 344±43, F=-3.50, P<0.001); long run emphasis of GLRLM (0.78±0.15, 1.12±0.12, 1.76±0.31, F=-4.13, P=0.006), run length non-uniformity and run percentage (71.7±13.9, 96.6±10.7, 104.1±13.5, F=-0.98, P=0.001;0.91±0.05, 0.84±0.21, 0.72±0.17, F=2.97, P=0.010); coarseness and busyness of NGTDM [0.09±0.01, 0.13±0.03, 0.26±0.07, F=-1.95, P=0.003;0.16(0.04, 4.14), 0.32(0.05, 9.84), 0.45(0.15, 10.14), H=-3.24, P=0.030], short-zone emphasis and short-zone high gray length emphasis of GLSZM (4.74±0.45, 3.44±1.03, 1.88±0.67, F=-3.14, P=0.040; 278 963±239, 164 607±544, 111 653±618, F=-3.84, P=0.001) among three groups. Multivariate Logistic regression showed that duration of hypoglycemia, NBNA score, energy, kurtosis, run percentage and short zone effect were independent risk factors for poor prognosis of neonatal HE ( OR=7.43, 4.09, 1.10, 2.11, 1.36, 1.68, P=0.002, 0.027, 0.001, 0.006, 0.007, 0.010, respectively). ROC curve showed that for combined hypoglycemic duration, NBNA and texture parameters, the area under the curve (AUC) was the highest (AUC=0.94, P<0.001). Conclusion:Texture analysis of the MRI diffusion weighted imaging can predict the prognosis of neonatal hypoglycemic encephalopathy at an early stage, which has better prediction efficiency when combined with clinical features.

BACKGROUND AND OBJECTIVES: The aim of this study was to determine the efficacy of induction chemotherapy with docetaxel and platinum in patients with hypopharyngeal carcinoma. SUBJECTS AND METHOD: The medical records of 66 patients who were diagnosed with hypopharyngeal carcinoma at our department from January 1996 to December 2008 were reviewed and retrospectively analyzed. The patients were divided into four groups according to treatment method: Group I was treated with radiation and induction chemotherapy consist of docetaxel and platinum (27); Group II was treated with surgery and induction chemotherapy consist of docetaxel and platinum (28), Group III was treated with radiation and induction chemotherapy consist of 5-FU and platinum (9) and Group IV was treated with surgery and induction chemotherapy consist of 5-FU and platinum (2). A total of 186 chemotherapy cycles were administered to patients and most of the patients received at least 2 cycles. RESULTS: The T-stage distribution at diagnosis was 7.5%, 42.4%, 28.8%, and 21.2% for T1, T2, T3, and T4, respectively. The N-stage distribution at diagnosis was 48.5%, 22.7%, 10.6%, 15.2%, and 9.1% for N0, N1, N2a, N2b, and N2c, respectively. The overall 3-year survival rate was 44.3%. The 3-year survival rate of each group was 42.6% in Group I, 54.8% in Group II, and 11.1% in Group III. There was no significant difference in survival between Groups I and III (p=0.074). There was no difference in sex, age, and N stage for 3-year survival rate. CONCLUSION: Although any valid conclusions could not be drawn because of the small number of patients examined here, induction chemotherapy consisting of docetaxel and platinum may improve the outcome of patients with hypopharyngeal carcinoma.

BACKGROUND AND OBJECTIVES: The aim of this study was to define the clinical characteristics and treatment outcome of the salivary Warthin's tumor in order to work out a therapeutic strategy. SUBJECTS AND METHOD: The medical records of 64 patients who underwent surgery and were pathologically diagnosed with Warthin's tumor at our department from January 1997 to December 2009 were reviewed retrospectively. RESULTS: There were 60 (94%) males and 4 (6%) females with an overall male-to-female ratio of 15 : 1. The average age was 59.8+/-9.2 years (range from 35 to 78). All tumors were found in the parotid gland. Of the 66 tumors, 31 (48%) occurred in the right side, 28 (44%) tumors occurred in left side, and 5 (8%) tumors occurred in bilaterally. A superficial parotidectomy was performed in 38 (59%) patients, lumpectomy in 25 (39%) patients and bilateral lumpectomy in one patient. There were 18 (28%) postoperative complications. The most common complication was transient facial palsy that occurred in 11 (17%) patients. Recurrence occurred in 2 (3%) patients, oneipsilaterally and the other contralaterally. All recurrences were found in patients who underwent superficial parotidectomy. CONCLUSION: Warthin's tumor has a very low recurrence rate with a benign nature. The study shows that lumpectomy is an effective surgical treatment for Warthin's tumor with an advantage of reducing facial nerve palsy and recurrence rate.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.
