Endoscopic posterior nasal neurectomy for the treatment of allergic rhinitis: anatomy and analysis of clinical efficacy / 中华耳鼻咽喉头颈外科杂志

Objective: To propose total posterior nasal neurectomy with transection of sphenopalatine neurovascular bundle from anatomy for the treatment of allergic rhinitis, and to explore its clinical application. Methods: Two fresh cadaveric heads (4 sides) were dissected through endoscopic transnasal middle meatus approach at Otorhinolaryngology Anatomy Laboratory of China-Japan Friendship Hospital. The structures of the craniofacial bone related to the surgical approach were observed. Twelve patients with allergic rhinitis who treated in Department of Otorhinolaryngology, China-Japan Friendship Hospital from Feb. 1 2019 to Jun. 10 2021 were selected. All the patients were treated by posterior nasal neurotomy with the technique of complete transection of sphenopalatine neurovascular bundle and followed up for 1 year after sugery. During the follow-up, 2 patients were lost. The other 10 patients included 4 males and 6 females, aging from 29 to 69 years. Visual Analogue Scale (VAS) and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) were used to evaluate the effect of the surgery. SPSS 25.0 software was used for statistical analysis. Results: Important anatomic landmarks of transnasal middle meatus approach were obtained during anatomy, such as ethmoid crest, sphenopalatine foramen/notch, palatine orbital process and sphenopalatine process. The postoperative VAS scores of nose, eye, pharynx, ear and whole body and total VAS scores were significantly lower than those before operation, with statistically significant difference (nose 2.50±1.70 vs 6.47±2.17, eyes 1.15±0.89 vs 3.60±2.57, pharynx 1.30±1.36 vs 4.25±3.64, ear 1.10±1.03 vs 2.67±2.00, whole body 1.08±1.24 vs 3.60±1.17, total 7.13±4.31 vs 20.58±9.05, all P<0.05). The postoperative RQLQ scores of sleep, nose, eyes, practical problems, emotion, activity and the total RQLQ scores of patients were significantly lower than those before operation, with statistically significant difference (sleep 0.80±0.69 vs 2.93±1.33, nose 1.38±1.18 vs 3.93±1.50, eyes 0.58±0.66 vs 1.80±1.25, practical problems 1.10±1.22 vs 3.03±1.84, emotion 1.00±1.81 vs 2.58±2.00, activity 2.77±2.93 vs 6.00±1.85, total 8.99±8.92 vs 22.42±8.69, all P<0.05). There was no significant difference in preoperative and postoperative scores of non-nasal/ocular symptoms (1.37±1.60 vs 2.16±1.12, P=0.166). There was no other complication except 2 cases with short-term postoperative numbness. Conclusions: Total posterior nasal neurectomy with transection of sphenopalatine neurovascular bundle is a safe, effective and feasible method for the treatment of intractable allergic rhinitis, and its long-term efficacy needs further observation.

Comorbidities in patients with cerebral palsy and their relationship with neurologic subtypes and Gross Motor Function Classification System levels / 中华儿科杂志

<p><b>OBJECTIVE</b>To analyze the comorbidities in patients with cerebral palsy (CP) from two perspectives as neurologic subtype and gross motor functions, and find their correlations.</p><p><b>METHODS</b>Children with cerebral palsy treated in the rehabilitation center from January 2007 to June 2009 received the following examinations: intelligence capacity test, ophthalmologic consultation, language-speech test, brainstem auditory evoked potential and electroencephalogram. They were stratified according to both neurologic subtype and gross motor functions to detect the occurrence of comorbidities.</p><p><b>RESULTS</b>Of all the 354 cases, 166 (46.89%) had mental retardation, 15 (4.24%) auditory limitations, 138 (38.98%) visual disorder, 216 (61.02%) language-speech disorder and 82 (23.16%) epilepsy. The frequency of individual comorbidities were distributed disproportionately between the different neurologic subtypes. Correlation analysis showed that there was a significant correlation between the spastic diplegia and the visual disorder (correlation coefficient = 0.26), between spastic hemiplegia and epilepsy (correlation coefficient = 0.17), between spastic quadriplegia and epilepsy and mental retardation (the correlation coefficient was 0.38 and 0.11, respectively) and between both dyskinetic and mixed children and language-speech disorder (the correlation coefficient was 0.24 and 0.27, respectively). The frequency of individual comorbidities was distributed disproportionately between the different neurologic subtypes and between the different GMFCS levels (P < 0.05), except for the frequency of visual disorders (chi(2) = 1.90, P > 0.05); and with the increase of the GMFCS levels, the burden of the comorbidities were more heavy and the incidence of the comorbidities was higher. Multi-comorbidities were relatively infrequently encountered in those with spastic hemiplegic or spastic diplegic children or patients whose GMFCS levels were I-III, while these entities occurred at a frequent level for those with spastic quadriplegic, dyskinetic, or mixed or children whose GMFCS levels were IV and V, and the differences were significant (P < 0.05). The mean GMFCS levels of children with spastic quadriplegic, dyskinetic or mixed CP were higher than level III, most of them had no ability of ambulation;while the mean GMFCS levels of spastic hemiplegic or spastic diplegic children were below level III, most of them could walk independently.</p><p><b>CONCLUSIONS</b>There are correlations between the occurrence of the comorbidities such as mental retardation, auditory or visual impairments, language-speech disorders, epilepsy and the cerebral palsy subtype and the gross motor function levels. Clinicians should have a full recognition of these comorbidities, and we should have a cooperation between the different subjects to have an overall evaluation and rehabilitation and to improve the prognosis.</p>

Expression features of P-glycoprotein, glutathione S transferase-pi and inhibitor of apoptosis proteins in lymph node metastases of gastrointestinal carcinomas / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the expression features of P-glycoprotein (P-gp), glutathione S transferase-pi (GST-pi) and inhibitor of apoptosis proteins like p53, survivin and bcl-2 in lymph node metastases of gastrointestinal carcinomas.</p><p><b>METHODS</b>The expression of P-gp, GST-pi, p53, survivin and bcl-2 were determined by using immunohistochemistry technique in surgical specimens of primary tumor (PT) and lymph node metastases (LNMs) from 54 gastrointestinal cancer patients with metastasis of lymph nodes. The expression difference of 5 multi-drug resistance (MDR)-related factors between LNMs and PT were compared.</p><p><b>RESULTS</b>Significant difference was found in the expression of P-gp and GST-pi between the two groups (both P < 0.05), and expression of p53 and bcl-2 showed positive correlation between LNMs and PT (r = 0.7248, 0.5524; both P < 0.05), respectively. In LNMs, P-gp expression was positively correlated with GST-pi (r = 0.4062, P < 0.05) and survivin (r = 0.6169, P < 0.05), and also GST-pi expression was related positively with survivin (r = 0.4027, P < 0.05). Statistically positive correlations were noted between bcl-2 and P-gp (r = 0.3986, P < 0.05), bcl-2 and survivin (r = 0.2937, P < 0.05), as well as GST-pi and survivin (r = 0.4481, P < 0.01) in PT. Only a positive correlation between GST-pi and survivin expression was simultaneously shown in both LNMs and PT.</p><p><b>CONCLUSIONS</b>There is significant heterogeneity of MDR-related factors expression in LNMs of gastrointestinal carcinomas. Effective adjuvant chemotherapy after operation should target on the metastatic loci of the disease.</p>

Oral motor dysfunction, feeding problems and nutritional status in children with cerebral palsy / 中华儿科杂志

<p><b>OBJECTIVE</b>This study was undertaken to investigate the clinical features of oral motor dysfunction and feeding problems as well as the nutritional status of children with cerebral palsy (CP).</p><p><b>METHODS</b>Fifty-nine CP children, 39 boys and 20 girls, mean age 31 months (20 to 72 months), were recruited. Their parents were interviewed for high risk factors and feeding history. Each case was assessed for oral motor and feeding problems based on oral motor and feeding skill score; for nutritional status by measurement of weight, height; neurologically for type of cerebral palsy and for developmental age by Gesell's developmental scale. Equal number of age and sex matched controls were included for comparison of nutritional status, oral motor and feeding skill score.</p><p><b>RESULTS</b>Among 59 patients, 51 cases had oral motor dysfunction and 55 cases had feeding problems including all athtosis, spastic tetraplegia, and 16 had spastic diplegia. The scores of both the mean oral motor function and feeding skill of CP children were significantly lower than those of the controls (P < 0.001). Main food of children with cerebral palsy consisted of liquid and semisolid diet. Body weight and height below the 25th percentile were found in 13 cases and 19 cases, respectively.</p><p><b>CONCLUSIONS</b>The majority of the children with cerebral palsy had oral motor dysfunction and feeding problems which appeared in early age and disturbed the growth and nutritional status. Thorough assessment for oral motor function, feeding problems and nutritional status of CP children is indicated in order to start timely rehabilitation and nutritional interventions which can significantly improve their nutritional status and quality of life.</p>
