Objective To explore the use of integrated two methods in vitro in prediction of eye irritation caused by cosmetics.Method Chorioallantoic membrane vascular assay ( CAMVA), bovine corneal opacity and permeability (BCOP) and Draize rabbit eye irritation test were used to determine the predictive potential of eye irritation of 60 kinds of cosmetics.Results CAMVA method was able to distinguish 41 non-irritant samples and 18 irritant samples.BCOP method was able to predict 35 non-irritant samples , 21 mild-moderate irritant samples and 4 severe irritant samples . Combination of CAMVA and BCOP methods could obviously improve the identification ability of irritation , and the classification consistency with Draize rabbit eye irritation testing reached 98.3%.Conclusions The integrated test strategy combined BCOP with CAMVA can be used to appropriately predict ocular irritation of cosmetics , with a prediction range covering non-irritant to severe irritant samples .

Objective: To investigate the clinical features of intracranial Castleman's disease, and to improve the understanding of the disease. Methods: The clinical features of one case of intracranial mixed type Castleman's disease, who was diagnosed in Department of Neurosurgery, Zhujiang Hospital, Southern Medical University in February 9, 2017, were retrospectively analyzed, and the relevant literatures about intracranial Castleman's disease were reviewed. The PubMed, Embase, Ovid, Cochrane, Wanfang Database and China Journal Full-text Database were searched using the keywords including "Castleman", "Intracranial"and "Central nervous system" for related literatures published between January 1, 1980 and January 31, 2017. Results: A 32-year old female was admitted because of headache for one month. CT examination showed an irregular and well-defined hyperdense lesion in the right temporo-parietal area with surrounding extensive edema and this mass was markedly contrast enhanced. Laboratory examination revealed anemia and hyperimmunoglobulinemia. The mass was removed completely by surgical resection. Postoperative pathology examination revealed mixed type Castleman's disease in the right temporo-parietal area. MRI was performed 3 months after the surgery. No residual tumor and recurrence were demonstrated. Seventeen related case reports were retrieved and 20 cases of intracranial Castleman's disease were reported. Among total 21 cases, there were 7 males and 14 females, ranging from 8 to 82 years old, and the median age was 47 years old. The mass arised from the dura matter or leptomeninges, and the most common sites of origin were located at the cerebral convexity and the parafalcine. The most common clinical features were seizures and headache. Radiographically, the previously reported cases presented as a homogeneously enhanced extra-axial well-defined mass with a marked peritumoral edema. Conclusion: Intracranial Castleman's disease is a rare clinical condition. The diagnosis can be made in combination with clinical findings and the laboratory examination.

[ ABSTRACT ] AIM: To investigate the expression and clinical significance of bone morphogenetic protein 3 (BMP3) in hilar cholangiocarcinoma tissues.METHODS: Thirty cases of hilar cholangiocarcinoma specimens were col-lected.The expression of BMP3 at mRNA and protein levels in the tumor tissues and paracancerous tissues was detected by real-time PCR and Western blot.The hilar cholangiocarcinoma paraffin-embedded specimens (n=103) were collected. The protein expression of BMP3 was determined by immunohistochemical method, and the relationship of BMP3 protein ex-pression with clinical pathological characteristics was evaluated.RESULTS:In the 30 patients with hilar cholangiocarcino-ma, the expressions of BMP3 protein and mRNA in 22 cases of tumor tissues were significantly decreased compared with the adjacent normal tissues.The results of immunohistochemistry showed that 87 cases were negative and 16 cases were weakly positive in all 103 cases of hilar cholangiocarcinoma.The expression of BMP3 protein was associated with the tumor TNM staging, lymph node metastasis and tumor differentiation (P<0.05).CONCLUSION:BMP3 gene might be inhibited in human hilar cholangiocarcinoma.The down-regulation of BMP3 gene might be associated with the carcinogenesis and devel-opment of hilar cholangiocarcinoma.

Objective]In order to study the impact of adenoid hypertrophy(AH)with allergic rhinitis(AR)in the otitis media with effusion(OME)in children,as well as to discuss the risk factors on the inducement of OME in patients with AH.[Methods]The clinical materials were collected and analyzed from 205 children with AH who admitted for surgical treatment between 2013 and 2015, including medical history and signs,acoustic immittance measurement,allergy screen as well as blood routine,and to evaluate the situation of OME and AR in patients with AH. All the data were analyzed by SPSS 20.0.[Results]Among the 205 AH children,66 cases(32.20%)were accompanying with OME. The AH patients aged 3-5 years had the highest incidence of OME,which decreased with age(P=0.018). It is significant on the prevalence of the OME in patients with AH between the two groups with and without AR (P = 0.010). In the logistic model investigating the risk factors of inducing OME among patients with AH,the third-degree AH, Type-three and the accompanying with AR were significant. The third-degree and third-type AH children were 2.729 and 6.390-folds higher than others respectively (P = 0.047,P = 0.001). The incidence of OME appeared to be 1.212-folds higher among patients with AR(P = 0.010).[Conclusion]Mechanical obstruction and AR played a superimposed role in the inducement of OME among patients with AH,which was effected by multiple factors. We should pay attention to the“lateral respiratory”allergic diseases on eustachian tube and middle ear.

With the development of early diagnostic and surgical techniques,the postoperative outcome of patients with liver cancer is gradually improved,but long-term outcome remains unsatisfactory.The therapeutic methods for recurrent tumors include multidisciplinary therapeutic methods such as reoperation,local treatment,and systematic treatment.Multidisciplinary therapies can improve the overall response of recurrent liver cancer,and it can combine various therapies from different disciplines according to the patient's condition and take advantages of each therapy in order to achieve the best therapeutic effect.

Objective To investigate the nursing of sedation and analgesia using low-dose fentanyl with midazolam during intra-arterial treatment with mechanical thrombectomy by means of stent for patients with anterior-circulation acute ischemic stroke.Methods All of 61 patients who underwent intra-arterial treatment with anterior-circulation acute ischemic stroke were retrospectively collected.They were divided into two groups according to the different program of individual conscious sedation:the control group(30 cases)used midazolam for intravenous maintain sedation,experimental group(31 cases)added the low-dose fentanyl on the basis of the control group.The thrombectomy was performed by the same group of interventional radiologists,while the effect of sedative,vital signs,respiratory curve and SpO2(blood oxygen saturation),assessment of Ramsay's sedation score,restlessness and other sedation adverse reactions were respectively observed in both groups.Nursing intervention was performed aiming at different states of patients during operation.Results All 61 patients were implemented with good medical care with no intracranial hemorrhage or intraoperative death.In the control group,there were 4 patients with Ramsay 1 point of sedation,resulted motion artifacts in digital subtraction angiography images in 3 of them,1 patient with slight reduction of SpO2,and vomiting in 4 patients.1 patient with decreased mean arterial pressure.In the experimental group,there was no Ramsay 1 point of sedative patient.The SpO2 was decreased in 5 patients.Respiratory inhibition occurred in 3 patients and the mean arterial pressure decreased slightly in the other 3 patients.Conclusions Application of low-dose fentanyl and midazolam is safe and reliable in patients who underwent intra-arterial treatment with anterior-circulation acute ischemic stroke.While closely observation to the changes of breath frequency curve and SpO2 in operation are very essential to actively prevent the occurrence of respiratory depression.
