Objective To summarize and analyze the clinical characteristic of blue rubber bleb nevus syndrome (BRBNS).Methods The clinical data of four cases treated since 2001 and 30 BRBNS cases reported by domestic literature were retrospectively analyzed.The clinical manifestation,family history,endoscopy and imageology examination,site of lesions,treatment and follow up were analyzed.Results The male to female ratio was 1.8∶1 and median age was 19.5 years.A total of 33 cases (97.1％) presented with gastrointestinal bleeding,median age of gastrointestinal bleeding detected was 9.0 years.Among the 33 cases,anemiawas found as the primary symptom in nine cases (27.3％),and one case complicated with intussusception and intestinal necrosis accompanied with abdominal pain.Two cases have family history.Gastroscopy (85.3 ％) and colonoscopy(73.5 ％) were mainly examinations for detection.Lesions mainly involved skin (100.0％) and digestive tract (97.1％),and the locations of the lesion in digestive tract was stomach (64.7％),small intestine (64.7％),colon (58.8％),esophagus (29.4％).Treatment methods included symptomatic treatment,endoscopic therapy and surgery.Banding ligation and polypectomy resection were common endoscopic therapies.Gastrointestinal bleeding did not recur in six cases with endoscopic therapy and four cases receiving surgery during short-term follow up.Conclusions BRBNS lesions mainly involve skin and digestive tract,mostly complicated with gastrointestinal bleeding.For gastrointestinal bleeding,so far endoscopic therapy and surgery are the effective therapies.

OBJECTIVE: To investigate the contralateral suppressions of transient evoked otoacoustic emissions (TEOAE) in diabetes mellitus patients with normal hearing. METHOD: The pure tone audiometry, acoustic immittance and TEOAE tests were performed in 30 diabetes mellitus patients with normal hearing and 30 healthy controls. The efferent system functions were evaluated by contralateral suppression of TEOAE. RESULT: There were no significant differences of pure tone thresholds and amplitudes of TEOAE between the two groups. The contralateral suppressions of TEOAE in diabetes mellitus patients were significantly lower than that in controls (P<0.05 at 2000 and 4000 Hz respectively). CONCLUSION The nerve functions of central nerve system can be damaged in diabetes mellitus patients with normal hearing.

Objective To investigate the relationship between the severity of insomnia and the curative effect in acute stage in patients with major depressive disorder (MDD). Methods The Insomnia Severity Index (ISI) was used to evaluate and group the severity of insomnia in the 57 patients with MDD. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. The 24－item Hamilton Depression Scale (HAMD24) was used to evaluate depressive symptoms, and the effect of acute stage (4～6 weeks) was evaluated with its reduction rate. The difference of curative effect was compared among patients with different insomnia levels. Results There was a significantly different recovery rate in acute stage in 3 groups of patients with mild, moderate and severe insomnia ( X2=22.34,P＜0.01). The severity of insomnia in patients with MDD (PSQI) was negatively correlated with the curative effect of acute stage (r=－0.44,P＜0.01). The total score, anxiety/somatization factor score, retardant factor score and despair factor score were significantly higher in severe insomnia group than in the moderate and mild insomnia groups after acute treatment (P＜0.01). Conclusion The severity of insomnia in patients with MDD can predict the curative effect in acute stage. The depressive patients with severe insomnia have residual anxiety/somatization, retardant, feelings of despair and other symptoms more obvious than mild and moderate insomnia patients after acute treatment.

Objective:To analyze the application of video nystagmography in the diagnosis and treatment of benign paroxysmal positional vertigo (BPPV) so as to provide evidence for clinical diagnosis.Methods:A total of 120 patients with suspected BPPV who received treatment in Yueqing People's Hospital from January to July 2020 were included in this study. There were anterior ( n = 24), posterior ( n = 80) and horizontal semicircular canal ( n = 16) BPPV according to the disease type. The detection rates of anterior, posterior and horizontal semicircular canal BPPV by video nystagmography and naked eyes were determined. Therapeutic effects of video nystagmography on three types of BPPV were compared. Results:The diagnostic rates of anterior, posterior and horizontal semicircular canal BPPV were 91.68%, 92.50% and 93.75%, respectively, and the difference was not statistically significant ( χ2 = 0.06, P > 0.05). The detection rates of anterior, posterior and horizontal semicircular canal BPPV by video nystagmography were 91.68%, 92.50% and 93.75% respectively, which were significantly higher than those by naked eyes (58.34%, 78.75%, 56.25%, χ2 = 7.11, 6.14, 3.86, all P < 0.05). After 1 week of treatment, total response rates of anterior, posterior and horizontal semicircular canal BPPV were 62.50%, 66.25%, 68.75%, respectively. After 3 months of treatment, total response rates of anterior, posterior and horizontal semicircular canal BPPV were 95.83%, 96.25% and 100.00%, respectively. There were no significant differences between anterior, posterior and horizontal semicircular canal BPPV after 1 week and 3 months of treatment ( χ2 = 0.18, 0.64, P > 0.05). At 3 months after surgery, the recurrence rates of anterior, posterior and horizontal semicircular canal BPPV were 4.16%, 5.00% and 6.25%, respectively, and the difference was not statistically significant ( χ2 = 0.08, P > 0.05). Conclusion:Video nystagmography is highly effective in the diagnosis and treatment of BPPV. It can accurately judge the occurrence of nystagmus in BPPV and increase the detection rate, which is worthy of clinical application.

Objective:To correlate climate change with epistaxis in Yueqing of Zhejiang province and to provide evidence for the diagnosis and treatment of epistaxis.Methods:A total of 1 800 patients with epistaxis, who received treatment in Yueqing People's Hospital between October 2018 and October 2019, were included in this study. The data of these patients were input into the Microsoft Excel software. They were summarized and sorted as per admission time. Climate change was correlated with epistaxis.Results:Daily average temperatures were negatively correlated with epistaxis ( r = -0.65, P = 0.003). A non-linear, inverted-U-shaped relationship was observed between daily relative humidity and epistaxis. When the daily relative humidity was < 65%, daily relative humidity was positively correlated with epistaxis ( r = -0.54, P = 0.007).When the daily relative humidity was > 65%, daily relative humidity was negatively correlated with epistaxis ( r = -0.68, P = 0.002). There was a nearly linear positive correlation between diurnal temperature range and epistaxis ( r = 0.52, P = 0.009). There was a linear and positive correlation between daily average atmospheric pressure and epistaxis ( r = 0.60, P = 0.004). The risk of epistaxis increased by 1.48% (95% CI: -2.15 to -0.81) when the temperature decreased by 1 ℃. When daily relative humidity was < 65%, the effects of humidity change on the risk of epistaxis were not statistically significant ( P > 0.05). When the relative humidity of the day was > 65%, the risk of epistaxis decreased by 1.82% (95% CI: -2.71 to -0.93) for every unit of humidity rise. The risk of epistaxis increased by 2.86% (95% CI: 0.54 - 5.18) for every 1 ℃ increase in temperature. The risk of epistaxis increased by 1.18% (95% CI: 0.50 - 1.87) for every 1 Pa increase in air pressure. Conclusion:Temperature change is negatively correlated with epistaxis. Atmospheric pressure and diurnal temperature range are positively correlated with epistaxis. Temperature change, atmospheric pressure, and diurnal temperature have temporary effects on epistaxis. High humidity has an obvious long-term protective effect against epistaxis.
