OBJECTIVETo explore evaluation strategies for middle ear dysfunction in cleft palate patients, to optimize the diagnosis and treatment of this dysfunction, and ultimately to improve the comprehensive treatment of cleft palate.

METHODSThe relationship among abnormal tympanic types (B, C, and Anomaly), effusion rate, tympanic pressure, and hearing loss were analyzed. We collected relevant information on 469 ears of cleft palate patients and traced one-year longitudinal changes in the tympana of 124 ears from 62 patients with both cleft lip and cleft palate.

RESULTSThe effusion rates of cleft palate patients with type B, type C, and type Anomaly were 50.3% (97/193), 34.8% (8/23), and 20.9% (53/253), respectively. The tympanic pressure of the ears with and without effusion showed no significant difference (P>0.05). The hearing loss in type B cleft palate patients with middle ear effusion was worse than that in patients without effusion (P=0.001). However, the hearing loss in type Anomaly showed no difference (P>0.05). The constituent ratio of each tympanic type remained constant during the period between cheiloplasty and palatoplasty for cleft lip and palate patients (P>0.05).

CONCLUSIONCleft palate patients of all tympanic types may all suffer from middle ear effusion at different rates. Examination by centesis is suggested for ears with abnormal tympanic types. Early aggressive therapy is essential for type B cleft palate patients with middle ear effusion to avoid hearing loss. However, catheterization may be not necessary for type Anomaly patients, and conservative observation should be performed instead. Myringotomy with grommet insertion during palatoplasty does not delay treatment timing for patients with both cleft lip and cleft palateg.

Objective To investigate the correlation between toll-like receptor 9 (TLR9) gene 2848G/A polymorphism and primary antineutrophil cytoplasmic antibodies (ANCA) associated small vasculitis (AAV). Methods A case-control study was performed among 135 patients diagnosed with AAV and 140 disease-free control and we test the serum biochemical parameter. Polymorphism was analyzed by polymerase chain restricted fragments length polymorphism. As for statistic method, according to the character of data, we performed t-test, chi-square test, Spearman grade related analysis and one-way ANOVA. Results ① The frequencies of AA, GG, GA genotype of TLR9 2848 in AAV patients were 14.07%, 38.52%, and 47.71%, respectively; ② Significant increase in IgM was observed in AA genotype than GG+GA genotype in AAV patients (F=4.561, P<0.05). ③ There was no significant difference between AI and CI in AA, GA and GG genotype in AAV patients (F=2.115, 0.760, P>0.05). Conclusion AA, GA and GG genotypes are detected in TLR9 2848G/A in patients with AAV in Guangxi, without significant correlation with susceptibility to primary AAV in Guangxi.

Objective To study the protein expressions of Fas-associated death domain protein (FADD) and caspase-8 in rats with intracerebral hemorrhage ,and the effects of erythropoietin tp reveal the mechanism of neu-m-protection by EPO. Methods 126 male SD rats were randomly divided into three groups: Sham-operated group, intracerebral hemorrhage group, and EPO group. Each group was divided into seven subgroups according to the differ-ent time points (3,6,12,24,48,72 h and 7 d). The model of intracerebral hemorrage was established in rats by in-tracerebral injection of autogenous blood. The protein expressions of FADD and caspas-8 in rats tissue around the hemorrhagic and the normal brain tissue were detected by immunohistochemistry. Results The protein expressions of FADD and caspase-8 were increased [(4.66±0.46 ) and ( 15.89±1.81)] at 3 h after intracerebral hemorrhage, and peaked at 48 h [ (35.88±4.24 ) and (45.04±3.99)], the expressions of FADD and caspas-8 in the region around hematoma in EPO group significantly decreased compared with model group[ (3.92±0.64) and (28.24±1.90), (13.32±2.01 ) and (35.08±2.82)] at 3 h and 48 h. Conclusion The protein expressions of FADD and easpase-8 are markedly increased after intracerebral hemorrhage. EPO can protect the neurons by signifi-cantly reducing the expressions of FADD and caspase-8.

A total of 105 patients with first-episode schizophrenia (male =51,female =54) and 99 normal controls (male =51,female =48) were included into this retrospective case-control study.Childhood trauma questionnaire-28 item short form (CTQ-SF) was used to assess the experience of childhood abuse.The result of binary logistic regression showed that emotional abuse (β =0.630,P ＜ 0.05) and emotional neglect(β =0.270,P ＜ 0.05) were included into the final model of predicting schizophrenia.It indicates that patients with first-episode schizophrenia experienced more early life stress than controls.Particularly emotional abuse and emotional neglect may play important roles in the onset of schizophrenia.

BACKGROUND:Fast track surgery, also cal ed enhanced recovery after surgery, is a series of optimal measures adopted during the perioperative period on the basis of evidence-based medicine, to reduce the physical and mental trauma brought to the patient and accelerate their recovery. It has become the research focus of orthopedic clinic as the surgery and anesthesia skil s are improved a lot in recent years, especial y the articular surgery, which has been widely used in clinics. OBJECTIVE:To summarize the clinical study of the application of optimal measures in joint replacement surgery both at home and abroad in recent years. METHODS:The first author searched related articles in PubMed and Chinese Journal Ful-text Database from January 1997 to September 2016. The key words were“joint replacement, enhanced recovery after surgery, multi-mode analgesia, diet management, steroid hormones”. 81 articles were found at last and one monograph was included. RESULTS AND CONCLUSION:(1) We found that the recovery plan reduced the hospital stays of the patients from 4-12 days to 1-3 days, including pre-operative health education, shortening fasting and water-depriving duration before surgery, super-anesthesia before surgery and do not place catheter;adopting general anesthesia and appropriate adductor canal to relieve the pain, and stopping bleeding using tranexamic acid during operation;multi-mode analgesia, faster function exercise after anesthesia recovery, and drinking water in early phase after surgery during the perioperative period of joint replacement surgery conducted by the cooperation of surgeon, anesthetist, nurse and nutritionist. There were no significant improvements of postoperative complications rate and rehospitalization rate. (2) The research found that, enhanced recovery after surgery is suitable for most of the patients receiving joint replacement surgery, including those in advanced age, combined heart and lung disease before surgery, type 2 diabetes and smoking and drinking before surgery.

Objective: To understand the relationship between coxsackievirus B and pediatric diseases. Methods: The infectious state of coxsackievirus B in hospitalized children were studied. Among 796 children studied, there were 218 upper respiratory tract infection cases, 179 pneumonia, 106 asthma, 155 myocarditis, 19 allergic purpura and 89 other diseases. The antigen (CVB-Ag) and IgM (CVB-IgM) were detected using ELISA method. Results: (1)There were 47% positive of CVB in upper respiratory tract infection and 48% positive of CVB in pneumonia(no difference between them, P>0.05). (2) There were 62% positive of CVB in asthma, 61% positive of CVB in myocarditis and 68% positive of CVB in allergic purpura(no difference among them, P>0.05)； But the positive rate of CVB in asthma, myocarditis and purpura were higher than in upper respiratory tract infection and pneumonia, (P<0.05). (3) There were lower positive rate of CVB in other kinds of diseases (16%) and in healthy children (3%)(no difference between them, P>0.05). Conclusion: CVB infection was related to several kinds of diseases, the relationship between CVB infection and diseases such as asthma, myocarditis, and allergic purpura should be further studied.

OBJECTIVETo observe the neurological protection effects of "paraplegia-triple-needling method" on rats with incomplete spinal cord injury (SCI), so as to make a preliminary exploration on its mechanism.

METHODSA total of 45 SD rats were randomly divided into a paraplegia-triple-needling method group (group A), a regular acupuncture group (group B) and a model group (group C), 15 rats in each one. The rats model of incomplete spinal cord injury was established by modified Allen's method. The acupoints of governor vessel and back-shu points next to the vertebras of upper end and lower end of injured segment as well as motor points in key muscle of lower extremities were treated with acupuncture in the group A; the acupoints of governor vessel and back-shu points next to the vertebras of upper end and lower end of injured segment as well as "Huantiao" (GB 30), "Housanli" (ST 36), "Yanglingquan" (GB 34) and "Genduan"(Extra) were treated with acupuncture in the group B; rats in the group C received no treatment after model establishment but grabbing and immobilization. The needles were retained for 15 min in the group A and group B, once a day for 14 times. 1 d, 7 d and 14 d after model establishment, Basso Beattie Bresnahan (BBB) scores were observed in each group; the morphologic change of injured spinal cord and expression of positive cells of calcitonin gene-related peptide (CGRP) were observed. Results (1) One day after SCI, there was no significant difference of BBB scores among three groups (P> 0. 05); 7 days and 14 days after SCI, BBB scores in the group A and group B were significantly superior to those in the group C (all P<0. 05), and the BBB scores in the group A were superior to those in the group B ( both P<0. 05). (2) There was expression of CGRP positive cells in all three groups, and that in the group A and group B was significantly higher than that in group C (both P<0. 05); 14 days after treatment, the expression in the group A was higher than that in the group B (P<0. 05).

CONCLUSIONThe "paraplegia-triple-needling method" could obviously! improve the motor function of rats with SCI, especially the expression of neuroprotective factor CGRP, which is likely to be one of the mechanisms of neurological protection effect.
