Objective To evaluate the different effects of gastric banding (GB) and sleeve gastrectomy (SG) on diet-induced obese rat model.Methods The obese rat model was established via the diet-induced method,and then underwent SG,GB,or sham-operation (SO) procedures.The different effects of SG,GB,and SO on these rats were evaluated at the 14th,28th and 56th day after operation.Results After 7 weeks' feeding,31rats in high-diet group reached the modeling standard.The model success rate was 88.6％ (31/35).GB and SG group showed significantly less cumulative food intake than SO group ( P ＜ 0.01).There was no significant difference between GB and SG group in cumulative food intake ( P ＞ 0.05 ).The average weight of rats in GB and SG group was (609.1±6.0) g and (591.6 ±4.3) g respectively at the 56th day after operation while it was (649.8 ± 10.0) g for SO group.The difference had statistical significance ( P ＜ 0.01).SG group showed better improvement effects on TC,TG,FFA,LDL-c and HDL-c than GB group (P ＜0.05).The postoperative ghrelin level in GB and SG group all decreased constantly and it decreased slower in GB group than in SG group.At the 56th day after operation,the ghrelin level in GB and SG group reduced from (1151.0 ± 144.2) pg/ml and (1148.2±127.2) pg,/ml to (992.0+121.9) pg/ml (P＜0.05) and (761.0+125.3) pg/ml (P＜0.01) respectively.The leptin level in GB and SG group all showed decreasing tendency.However,the leptin level of the 2 groups presented significant difference at the 56th day after operation.Conclusions There is no significant difference between GB and SG group in postoperative cumulative food intake.However,SG has better effects on controlling weight gain and improving blood lipids than GB.The different effects of GB and SG on the level of ghrelin and leptin in rats may account for the different curative effects.

0.05) except for 8 kHz. Air conduction thresholds were basically normal in children's simple type CSOM, whereas hearing loss during intermediate frequency and high frequency in adults with osteitis and cholesteatoma type was more severe than that in children.Conclusion Hearing-loss in children's CSOM was the same as adult patients, although course of disease was not long in children. Inner ear was not or mildly impaired in children's CSOM.

[ABSTRACT]OBJECTIVETo evaluate the short-term efficacy of Eustachian tube balloon dilation (ETBD) in the treatment of symptomatic Eustachian tube dysfunction (SETD) by subjective and objective analysis.METHODS Forty patients who underwent ETBD were included. Subjects’ inclusion criteria were as followed: symptoms of ETD (aural fullness predominantly, with or without otalgia, muffle hearing and tinnitus), normal tympanic membrane, type A or C tympanograms, and without a history of any middle ear diseases. Main outcomes including subjective improvement, otoscopy, pure-tone audiometry, impedance audiometry, R-value in tubomanometry (TMM) and Eustachian Tube Score (ETS) were assessed 1 week and 6 months postoperatively.RESULTSAll cases were dilated successfully. A significant effect of treatment was documented when measuring subjective improvement, impedance audiometry, R-value in TMM and ETS 1 week and 6 month postoperatively. Subjective symptoms were not relieved only in one patient. The overall success rate for all patients was 98%.CONCLUSIONETBD can provide short-term benefits to those who are diagnosed with SETD and refractory to medical management. SETD might be an optimal indication for ETBD in the treatment of ETD.

OBJECTIVE: To investigate the effect of Eustachian tube balloon dilation (ETBD) in treatment of eustachian tube related diseases. METHOD: Fifteen cases (20 ears) of otitis media with effusion and 22 cases (30 ears) of symptomatic Eustachian tube dysfunction were recruited. Technique of tubomanometry (TMM) showed obstructive Eustachian tube dysfunction in all patients. All the patients were received ETBD and followed up with VAS evaluation of ear fullness, muffled hearing, poping sound in the ear and tinnitus. And also the TMM change and middle ear effusion. RESULT: Ear fullness, muffled hearing released with 1 week (ear fullness: 8.2 ± 1.4 vs. 2.0 ± 1.2, P < 0.05, muffled hearing: 6.2 ± 1.2 vs. 3.1 ± 0.8, P < 0.05). No recurrence was seemed within 6 months. The eustachian function test turned better. Symptomatic Eustachian tube dysfunction had an effective rate of 96.6% while otitis media with effusion was 95.0%. CONCLUSION ETBD have good short-term effect in obstructive eustachian tube dysfunction related middle ear dysfunction, which might provide a good way to solve the eustachian tube related diseases.

Objective To explore the influence of modified radical gastrectomy on glycometabolism in patients with gastric carcinoma and non-obese T2DM.Methods The retrospective study was carried out to analyze the changes of glycometabolism between preoperative and postoperative follow-up in 25 patients with gastric carcinoma and non-obese T2DM.The above parameters included fasting plasma glucose (FPG),2-hour postprandial blood glucose (2 h PBG),glycosylated hemoglobin A1c (HbA1c),fasting insulin (FINS),homeostasis model assessment-insulin resistance (HOMA-IR),fasting glucagon-like peptide-1 (GLP-1),and glucose-dependent insulinotropic polypeptide (GIP).Results At the 6th and 12th month after operation,the related parameters such as FPG,2 h PBG,HbA1c,FINS and HOMA-IR were (7.54±1.44) mmo]/L and (7.17±1.35) mmol/L,(9.97±1.59)mmol/L and (9.47±1.23) mmol/L,(6.46±0.74)％ and (6.31±0.97)％,(7.73±0.98) μIU/ml and (7.44±0.96) μIU/ml,1.10±0.15 and 1.04±0.14 respectively.The above indexes were significantly improved compared with those before operation (P＜O.05).The levels of fasting GLP-1 at 6th and 12th month after operation were (2.27±0.25) pmol/ml and (2.33±0.27) pmol/ml respectively,and there was no significant change compared with those before operation (P＞0.05).On the contrary,the levels of GIP at 6th and 12th month after operation are significantly decreased compared with that before operation,which were (7.23±1.33) pmol/ml and (6.40±1.20) pmol/ml respectively.Conclusion The modified radical gastrectomy can improve T2DM in patients with gastric carcinoma markedly,even curing some patients,which may be related to the decrease of fasting GIP after operation.

OBJECTIVE: To investigate the characteristic of nystagmus and treatment of horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV). METHOD: The positioning nystagmic features in 43 patients with HSC-BPPV treated between April 2004 and October 2006 were recorded and analyzed with video nystagmography. After the subtype and the effect side were determined, the appropriate repositioning maneuvers were chosen. RESULT: (1) Geotropic nystagmus was recorded in 27 cases, of whom 19 cases were treated with barbecue maneuver and/or combined forced prolonged position maneuver, while the others were treated with Asprella's maneuver. (2) Apogeotropic nystagmus was recorded in 16 cases with two types, one of which could turn into geotropic nystagmus with Gufoni's maneuver or spontaneously (in 12 cases), the other type could not (in 4 cases) transform accepted barbecue maneuver and/or combined forced prolonged position maneuver. The total improvement rate was 72.1% after 1 week and 81.4% 3 months later respectively. CONCLUSION The otolith position and the pathogenesis could be distinguished according to the nystagmic characteristics and type of HSC-BPPV. It was necessary to apply the appropriate repositioning maneuvers to treat HSC-BPPV.

OBJECTIVE: To explore the different and common features between adults and children with otitis media with effusion (OME) on course of disease, clinical characteristics and audiometric changes. METHOD: Pure tone audiometry, tympanogram and clinical information were analyzed and compared between 34 cases of adults and 42 cases of children with OME. RESULT: The course of disease was relatively short in children. The adenoid vegetation inflammation was more frequently found in children, while the OME occurred more often in adults. The air conduction and bone conduction threshold increased both in children and adults, particularly at high frequencies of 2 and 4 kHz. The bone conduction threshold at 4 kHz in adults was significantly higher than that in children (P < 0.05). In the cases with C type tympanogram, the negative pressure in adults was even lower than that in children (P < 0.05). CONCLUSION The OME in children is often relatively shorter in course of disease, which is mainly caused by adenoid vegetation. Sensorineural deafness can occur both in children and adults, especially at high frequencies. OME in children is less severe, however, it may lead to negative effects in learning and cognition, which should be diagnosed and managed in time.

Objective:To investigate the effect of low molecular weight heparin (LMWH) on the inflammatory response of PC12 cells induced by oxygen glucose deprivation (OGD) and its related mechanism.Methods:The PC12 cells were cultured in vitro were randomly divided into sham(control) group, OGD group, LMWH group and blocking agent group. The latter group was divided into six groups: Eritoran+ OGD group, LMWH+ Eritoran+ OGD group, ST2825+ OGD group, LMWH+ ST2825+ OGD group, pyrrolidinedithiocarbamate (PDTC)+ OGD group and LMWH+ PDTC+ OGD group. OGD cell model was established. Cell counting kit-8 (CCK-8) assay was used to detect cell activity. The expressions of toll-like receptor 4 (TLR4), MyD88 and nuclear factor κB (NF-κB) mRNA and protein were detected by real time polymerase chain reaction (qRT-PCR) and Western blot. The concentration of interleukin (IL)-1β, IL-6, tumor necrosis factor-α(TNF-α) and S100β were determined by enzyme linked immunosorbent assay (ELISA). Results:The cell activity of OGD group was significantly lower than that of control group on the first, second, third day ( P<0.05). Compared with OGD group, the activity of LMWH group was increased on the second, third day ( P<0.05), but lower than that of control group ( P<0.01). The mRNA expression of TLR4, MyD88 and NF-κB was significantly increased in OGD group compared with the control group ( F=144.9, F=710.5, 79.51, P<0.01). Compared with OGD group, the mRNA expression of TLR4, MyD88 and NF-κB were significantly decreased after treatment with LMWH ( P<0.01), and the specific inhibitor of TLR4, MyD88 and NF-κB enhanced the anti-inflammatory effect of LMWH. The protein expression of this pathway was consistent with that of the gene. The concentration of IL-1β, IL-6, TNF-α and S100β in OGD group was significantly higher than control group ( P<0.05). After treatment with LMWH, the concentrations of inflammatory factors and S100β were significantly decreased compared with OGD group ( P<0.01). When hinder TLR4, MyD88 and NF-κB respectively by Eritoran, ST2825 and PDTC, the concentrations of inflammatory factors and S100β were significantly decreased, but it was still higher than control group ( P<0.05). Conclusions:OGD can cause pathological damage of PC12 cells, including high expression level of S100β and aggravation of inflammatory reaction. LMWH can improve cell activity, down-regulate inflammatory reaction degree and protect the cells. Using inhibitors of TLR4/MyD88/NF-κB pathway to inhibit the corresponding target, the up-regulation of inflammatory factors by OGD can be inhibited in varying degrees. These suggested that LMWH may regulate inflammatory reaction of PC12 cells induced by OGD through TLR4/MyD88/NF-κB pathway.

Objective:To investigate the value of ultrasonography in diagnosis of transposition of great arteries of the fetus at 11-13 + 6 weeks gestation. Methods:A prospective study was conducted on fetuses screened by ultrasound in the first trimester in Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region between January 2015 and March 2022. Fetal heart structure was screened by three-section screening method. Fetuses with suspected transposition of the great arteries at 11-13 + 6 weeks gestation underwent followed-up ultrasound examination, chromosome and gene test results. The ultrasound characteristics and prognosis pregnancy outcomes were summarized. Results:Twenty-one cases of transposition of the great arteries were detected by ultrasonography, including complete transposition of great arteries (20 cases) and congenitaly corrected transposition of the great arteries (1 case). Two cases were miss diagnosed. Twenty-one cases showed parallel signs of two major arteries on grayscale outflow section at 11-13 + 6 weeks gestation. There were 6 cases with aneuploid ultrasonographic soft markers abnormality, 2 cases with extracardiac malformation. Chromosome and microarray analysis were performed in 13 cases. 4 cases with chromosomal abnormality. Four cases of chromosomal abnormalities were associated with ultrasonographic soft markers abnormality, and 1 case with extracardiac malformation.In the 23 cases, 20 cases were induced, 1 miscarried, and 2 delivered to term. Among the fetuses delivered at term, 1 case died before neonatal operation and 1 case survived. Conclusions:Standardized ultrasound scan at 11-13 + 6 weeks has high accuracy in diagnosis of transposition of the great arteries. And the incidence of chromosomal abnormality is high with ultrasonographic soft markers abnormality or extracardiac malformation.
