OBJECTIVE To study whether immunosuppressant(IS,cyclophosphamide,CPA) have the function of prevention and treatment of congenitalautoimmune sensorineural hearing loss or not.METHODS The female guinea pigs were immunized by crude conspecific inner ear antigens(CIEAgs),and took orally IS or not at the same time during gestation.Then the pregnant guinea pig's and their offspring's hearing function were measured and inner ear histopathologic changes were observed.Some of offspring borne by the female guinea pigs which immunized with CIEAgs and not treated with IS showed hearing loss and were treated by IS,and their hearing functions were measured and inner ear histopathologic changes were observed with same techniques.RESULTS After immunizing with CIEAgs,some of female guinea pigs which immunized with CIEAgs and not treated with IS showed different degrees of hearing loss(the thresholds of acoustic nerve compound active potential and cochlear microphonic potentials elevated) and immune inflammations in inner ear tissues.All females guinea pigs in experimental group which immunized with CIEAgs and treated with IS at same time,and their offspring have no any hearing loss and inner ear histopathologic changes.After IS therapy,the hearing function improved(mainly at the low-frequency region) in some offspring guinea pigs,which borne by the female guinea pigs which immunized with CIEAgs and not treated with IS.CONCLUSION IS could effectively prevent offspring's congenital sensorineural hearing loss induced by their mother's special antibodies against inner ear tissues antigens.IS showed effective result for treatment of congenitalautoimmune sensorineural hearing loss,but the curative effect was limited.

Objective To study the clinical diagnosis and treatment of malignant gastrointestinal stromal tumor. Methods To retrospectively analyze the clinical data of 28 cases with malignant gastrointestinal stromal tumors underweat surgical treatment . Results The malignant gastrointestinal stromal tumor in adults were more than 50 years old,71.4%(20/28) ,and common clinical symptoms were gastrointestinal bleeding,anemia,and pain. The lesion site: 19 cases of gastric bowel, 8 cases of small intestine, 1 case of colon, radical excision in 22 cases, local excision palliative resection in 5 cases, three cases were multi-visceral resection. Conclusion Malignant gastrointestinal stromal tumor could be diagnosed by the means of endoscopic imaging and clear,and preoperative diagnosis was difficult. Surgical resection was the pathology diagnosis and treatment of primary method,if necessary,to ensure multi-visceral resection of the tumor to prevent recurrence of thoroughness, had important significance.

Objective: To observe the effect of edaravone combining ulinastatin on brain protection in patients of type A aortic dissection (AAD) after total arch replacement. Methods: A total of 60 AAD patients with total arch replacement in our hospital from 2014-09 to 2016-01 were prospectively studied. Based on peri-operative application of edaravone and ulinastatin, the patients were divided into 2 groups: EU group: 1) the patients received ulinastatin 300000 U/8h and edaravone 0.5mg/Kg/12h from administration to 3 days post-operation, 2) during cardiopulmonary bypass, the patients received ulinastatin 300000 U/2h and edaravone 0.5mg/Kg; Control group, the patients had no such treatment.n=30 in each group. The following items were observed:①operative condition;②blood levels of speciifc brain injury markers as S-100 and neuron speciifc enolase (NSE) at different time points: beginning of surgery (T0), opening aorta clamp (T1), right after cardiopulmonary bypass (T2), entering ICU (T3), 24h post-operation (T4) and 3 days post-operation (T5); ③post-operative condition. Results:①Durations of operation, cardiopulmonary bypass, cardiac arrest and bilateral antegrade selective cerebral perfusion (BACP), the frequency of BACP and UACP (unilateral antegrade selective cerebral perfusion), the lowest rectal temperature and blood levels of S-100, NSE at T0 were similar between 2 groups.②Compared with Control group, EU group had decreased S-100 and NSE from T1 to T5,P<0.05.③The in-hospital and ventilation time, frequency of PND and TND, the patients with CSS score≥16 before discharge and the in-hospital death rate were similar between 2 groups,P>0.05. Conclusion: Edaravone combining ulinastatin had brain protective effect in AAD patients after total arch replacement;it may reduce blood speciifc brain injury markers while the clinical signiifcance should be further investigated.

Tinea of vellus hair is caused by dermatophyte infection of vellus hairs, and commonly affects children. It usually occurs on the face, and clinically manifests as annular or semi-annular erythema gradually spreading to the surrounding area, with central clearing and a slightly elevating border covered with papules and papulovesicles. Intense inflammation, which may manifest as pustules, erosions, exudation, scales and crusts, can be observed in patients with severe tinea of vellus hair. Direct microscopy of fungi showed abundant hyphae and/or spores on vellus hairs. Topical antifungal therapy is usually ineffective, and systemic antifungal therapy should be considered. In order to reduce the high rate of missed diagnosis and misdiagnosis, and to improve clinicians′ understanding of this disease, this review summarizes the incidence, clinical manifestations, diagnosis and treatment of tinea of vellus hair.

OBJECTIVETo summarize and analyze the clinical features, diagnosis, surgical approaches and treatment outcomes of patients with primary nasal sinus osteoma.
METHODSA retrospective review of 48 cases with primary nasal sinus osteoma treated from January 2007 to December 2013 was performed. All patients underwent preoperative CT scan and postoperative histopathologic examination. The surgical approaches included lateral rhinotomy in 14 cases, nasal endoscopic resection in 12 cases, coronal surgical incision craniotomy in 13 cases, combined craniofacial approach in 4 cases, and Caldwell-Luc approach in 5 cases.
RESULTSThe postoperative pathological diagnosis consisted of 3 variants, including 20 for compact type and 15 for cancellous type, and 13 for mixed type. Six cases were lost to follow-up and 42 cases were followed up for 6-60 months, 5 cases recurred. The post-operative complications included sinus mucous cyst in 4 cases, cerebrospinal fluid leak in 3 cases.
CONCLUSIONSNasal sinus osteoma are common. CT or MRI is helpful to evaluate the osteoma size, location and possible sources, and to make operation scheme. Surgery is the first choice for sinus osteoma. Lateral rhinotomy and nasal endoscopic resection can be applied to most sinus osteoma. The prognosis of sinus osteoma is good, with fewer recurrence.

OBJECTIVE:
To evaluate the efficacy and safety of Cidan Capsule combined with adjuvant transarterial chemoembolization (TACE) in patients with a high risk of early recurrence after curative resection of hepatocellular carcinoma (HCC).
METHODS:
A multicenter, randomized controlled trial was conducted in patients with high-risk recurrence factors after curative resection of HCC from 9 medical centers between July 2014 and July 2018. Totally 249 patients were randomly assigned to TACE with or without Cidan Capsule administration groups by stratified block in a 1:1 ratio. Postoperative adjuvant TACE was given 4-5 weeks after hepatic resection in both groups. Additionally, 125 patients in the TACE plus Cidan group were administrated Cidan Capsule (0.27 g/capsule, 5 capsules every time, 4 times a day) for 6 months with a 24-month follow-up. Primary endpoints included disease-free survival (DFS) and tumor recurrence rate (TRR). Secondary endpoint was overall survival (OS). Any drug-related adverse events (AEs) were observed and recorded.
RESULTS:
As the data cutoff in July 9th, 2018, the median DFS was not reached in the TACE plus Cidan group and 234.0 days in the TACE group (hazard ratio, 0.420, 95% confidence interval, 0.290-0.608; P<0.01). The 1- and 2-year TRR in the TACE plus Cidan and TACE groups were 31.5%, 37.1%, and 60.8%, 63.4%, respectively (P<0.01). Median OS was not reached in both groups. The 1- and 2-year OS rates in TACE plus Cidan and TACE groups were 98.4%, 98.4%, and 89.5%, 87.9%, respectively (P<0.05). The most common grade 3-4 AEs included fatigue, abdominal pain, lumbar pain, and nausea. One serious AE was reported in 1 patient in the TACE plus Cidan group, the death was due to retroperitoneal mass hemorrhage and hemorrhagic shock, and was not related to study drug.
CONCLUSIONS
Cidan Capsule in combination with TACE can reduce the incidence of early recurrence in HCC patients at high-risk of recurrence after radical hepatectomy and may be an appropriate option in postoperative anti-recurrence treatment. (Registration No. NCT02253511).
