The renal toxicity of rats after a single dose ofMeng-Gen-Wu-Su (mercury) processed products,Meng-Gen-Wu-Su (mercury)-18-composition pill, mercuric sulfide, mercuric chloride, and mercurous chloride was studied. Fifty-four male Wistar rats were randomly divided into nine groups according to body weights (6 rats in each group): normal control group, low and high dose groups (0.033, 0.33 g·kg-1·d-1) ofMeng-Gen-Wu-Su (mercury) processed products, low and high dose groups (0.29, 2.9 g·kg-1·d-1) ofMeng-Gen-Wu-Su (mercury)-18-composition pill, simplified prescription ofMeng-Gen-Wu-Su (mercury)-18-composition pill group (0.26 g·kg-1·d-1), mercuric sulfide group (17.39 mg·kg-1·d-1), mercuric chloride group (4.06 mg·kg-1·d-1) and mercurous chloride group (35.3 mg·kg-1·d-1). After acclimation for one week, once oral administration was given to each group of rats. After 24 h, function and morphological changes of liver and kidney were detected. Mercury accumulation in kidney was determined by inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma source mass spectrometer (ICP-MS). Apoptosis of renal cell was determined by terminal-deoxynucleoitidyl transferase mediated Nick End Labeling (TUNEL). Renal typeⅢ collagen protein's expression was determined by immunohistochemical (HIC) method and expression changes of MT-1, MT-2 mRNA in kidney were also determined by real-time fluorescence quantitative PCR (real-time-PCR). There was no significant difference of ALT, AST in serum between normal control group and other groups (P>0.05). CREA and UREA in mercurous chloride group were apparently higher than normal control group and low dose group of Meng-Gen-Wu-Su processed products (P<0.01). Hepatic and renal pathologic examination results showed that liver cell of low dose groups ofMeng-Gen-Wu-Su processed products andMeng-Gen-Wu-Su-18-composition pill swelled to a low degree and glomerular disease was not obvious. In high-dose groups ofMeng-Gen-Wu-Su processed products,Meng-Gen-Wu-Su-18-composition pill and mercuric sulfide group, liver and kidney appeared some pathological changes and such changes were more significant in mercuric chloride and mercurous chloride groups. Compared with normal control group and low dose group ofMeng-Gen-Wu-Su processed products, the mercury kidney volume in mercuric chloride and mercurous chloride groups increased significantly (P<0.01). The apoptosis rate of renal cell and expression of typeⅢ collagen protein increased significantly in the groups of mercuric sulfide, mercuric chloride and mercurous chloride (P<0.01). MT-1and MT-2 mRNA gene expression rised significantly in the groups of mercuric chloride and mercurous chloride (P<0.05 orP<0.01). In summary, the rats renal toxicity after a single dose ofMeng-Gen-Wu-Su (Mercury) processed products or MongolianMeng-Gen-Wu-Su (Mercury)-18-composition pill were both far less than that of mercuric chloride or mercurous chloride.

Objective To study the curative effect and the prognostic factors of endoscopic traumatic optic neuropathy (TON). Methods The clinical data of 53 patients with TON from 2010 to 2015 years was retrospectively analyzed. Divided the patients into the surgery group and the non-surgery group, according to whether or not accept the treatment of endoscopic optic decompression. And evaluating the potential prognostic factors in chi-square test, group t-test and multiple regression analysis. Results In 53 patients (55 eyes ), 31 eyes have no visual acuity before treated: 8 eyes’ visual acuity was improved in 16 eyes (8/16) that accepted operation; 3 eyes’ visual acuity was improved in 15 eyes (3/15) that with non-operation;24 eyes have visual acuity before treated:11 eyes’ visual acuity was improved in 14 eyes (11/14) that accepted operation;3 eyes’ visual acuity was improved in 10 eyes (3/10) that with non-operation;19 eyes’ visual acuity was improved in 30 eyes (19/30) that accepted operation, the total effective rate was 63.3%, and there was no complications happened in the patients who accepted operation. The age, eye-side, sex, visual acuity, optic canal fracture , orbit fracture , all these factors have no correlation to the prognosis (P>0.05), but the interval time between injury and operation (less than 3 days) and the way of the treatment are benefit to improve vision (P<0.05). Conclusions The endoscopic optic decompression is an effective treatment in TON, and it’s better to improve vision in 3-day after TON.

BACKGROUND:Mongolian Pharmaceutical Betel Shisanwei Ingredients Pil has achieved good clinical efficacy, but the underlying mechanism remains unclear. OBJECTIVE: To study the effects of Mongolian Pharmaceutical Betel Shisanwei Ingredients Pil on the hypothalamic-pituitary-adrenal axis negative feedback function in the chronic depressed rats, and to explore anti-depression mechanisms of Mongolian Pharmaceutical Betel Shisanwei ingredients pil. METHODS: Eighty male Wistar rats were randomly divided into ten groups according to the sugar consumption test (with eight rats in each group): normal control group, model group, fluoxetine group, high-, medium- and low-dose Betel Shisanwei Ingredients Pil groups, RU486 group, high-, medium- and low-dose Betel Shisanwei Ingredients Pil plus RU486 groups. Except normal control group, the other groups were treated with the chronic unpredictable mild stress stimulation combined with lonely rising, to establish depression models. In the meantime, rats of the high-, medium- and low-dose Betel Shisanwei Ingredients Pil groups were given oral gavage of Betel Shisanwei Ingredients Pil (0.2, 0.4, 0.8 g/kg) for 28 days; rats of the normal control group and model group were intragstricaly administered with sodium carboxymethyl celulose; rats of RU486 group were given abdominal subcutaneous injection of RU486 from day 21 after modeling; rats of the high-, medium- and low-dose Betel Shisanwei Ingredients Pil plus RU486 groups were intragstricaly administered with Betel Shisanwei Ingredients Pil (0.2, 0.4, 0.8 g/kg) and subcutaneous injection of RU486 from day 21. RESULTS AND CONCLUSION:Compared with normal control group, cortisone content increased significantly (P < 0.05), the expression of glucocorticoid receptor mRNA in hippocampus, hypothalamus and pituitary gland decreased significantly, and hypothalamic corticotrophin releasing hormone mRNA expression increased significantly in the model group and RU486 group. Compared with model group, cortisone content decreased, the expression of glucocorticoid receptor mRNA in hippocampus, hypothalamus and pituitary gland increased significantly, and hypothalamic corticotrophin releasing hormone mRNA expression decreased significantly in rats treated with Betel Shisanwei Ingredients Pil. Compared with RU486 group, Betel Shisanwei Ingredients Pil administration led to changed in cortisone content, glucocorticoid receptor mRNA expression in hippocampus, hypothalamus and pituitary gland, as wel as hypothalamic corticotrophin releasing hormone mRNA expression. Experimental findings indicate that, Betel Shisanwei Ingredients Pil can directly regulate excessive secretion of glucocorticoid, and improve the dysfunction of hypothalamic-pituitary-adrenal axis central negative feedback through increasing glucocorticoid receptor mRNA expression and decreasing corticotropin releasing hormone mRNA expression. After the hypothalamic-pituitary-adrenal axis negative feedback pathway is blocked, the effect of Betel Shisanwei Ingredients Pil is weakened.

The frequency of P1PK and GLOB blood group were analyzed. 【Results】 Six cases of anti-PP 1P^k(formerly known as anti-Tj^a) negative blood type were identified as the rare P1-PK-P- blood type (formerly known as Tj^a- blood type or p blood type, hereinafter referred to as p blood group) from 300 Lahu population, with phenotypic frequency of p blood group in P1PK and GLOB blood group system in Lahu population at 2.0%(6/300). 【Conclusion】 The phenotypic frequency of blood group p in Lahu population was significantly higher than that in Europe (5.8 persons per million) and Hong Kong, China (1 person per million),indicating significant ethnic specificity and regional ethnic differences.

Objective:To study the changes and imaging features of arachnoid granulation (AG) in patients with cerebral venous sinus thrombosis (CVST).Methods:The clinical and imaging data of 35 patients with idiopathic CVST confirmed by MR imaging combined with CE-MRV or DSA in our hospital from January 2013 to December 2018, and 35 healthy controls collected at the physical examination center at the same time period were detected. The sizes and numbers of AG were compared between the two groups, and the MR imaging features of CVST and AG in patients with CVST at different courses were compared.Results:(1) In 35 patients with CVST, AG was found in 14 patients, and the average diameter was (5.19±2.40) mm, ranged from 1.83-11.77 mm; in the control group, AG was found in 23 patients, and the average diameter was (4.45±2.03) mm, ranged from 1.45-9.87 mm; no statistical difference was noted in diameter between the two groups ( t=2.121, P=0.221), and the number of AG showed statistical difference between the two groups (χ 2=4.644, P=0.031). (2) In 8 patients with CVST at acute phase, CVST showed hypointense on T2WI and FLAIR; in 20 patients with CVST at subacute phase, CVST showed hyperintense on T2WI and FLAIR; in 7 patients with CVST at chronic phase, CVST showed hyperintense on T2WI and FLAIR. At any stage of venous sinus thrombosis, AG showed high signal on T2WI and low signal on FLAIR. Conclusion:AG detection rate in CVST patients is lower than that in normal controls; MR imaging T2WI and FLAIR sequences could effectively distinguish CVST with AG.

Objective:To explore the diagnostic values of MRI T2WI and 3D contrast enhanced magnetic resonance venography (3D CE-MRV) in transverse sinus arachnoid granulations (AGs).Methods:Clinical data were obtained from 811 patients who were subjected to non-contrast MR imaging and 3D CE-MRV between January 2016 and April 2019 in our hospital. And the number of patients whose transverse sinus AGs could be shown by T2WI and MRV, the number, size, and shape of AGs, and the number of AGs-related veins were recorded.Results:MRI T2WI showed 242 AGs in 184 patients (22.7%), and 3D CE-MRV showed 138 AGs in 119 patients (14.7%); MRI T2WI had a significantly higher percentage in showing AGs patients as compared with 3D CE-MRV ( P<0.05). Two hundred and forty-two AGs showed by MRI T2WI were divided into 3D CE-MRV observation group ( n=138) and 3D CE-MRV non-observation group ( n=104); the diameter of AGs in the 3D CE-MRV non-observation group ([5.30±2.10] mm) was significantly smaller than that in the 3D CE-MRV observation group ([6.14±2.03] mm, P<0.05). MR T2WI showed that 231 AGs were like circles or ellipses and 11 AGs were like fractal; while 3D CE-MRV showed that 138 AGs were like circles or ellipses and 0 AG were like fractal. MRI T2WI showed that 289 veins were closely related to AGs, and 3D CE-MRV showed that 97 veins were closely related to AGs. MRI T2WI could demonstrate significantly higher proportion of non-labbe veins which were closely related to AGs than 3D CE-MRV ( P<0.05). Conclusion:As compared with 3D CE-MRV, T2WI can find larger number of AGs in the transverse sinus, and better display the shape of AGs and the vein adjacent to them.

【Objective】 To construct an in-vitro model of erythrocyte antibody-mediated complement activation, and establish quantitative detection methods based on flow cytometry and spectrophotometry, so as to explore the correlation of anti-body titers and complement activation speed, and provide a methodological basis for studying the adverse transfusion reactions of anti-body mediated complement hemolysis. 【Methods】 Mouse monoclonal antibody that recognized human C3b and fluorescent secondary antibody were used to label C3b fragments on erythrocytes, and the deposition of C3b fragments after complement activation was detected by flow cytometry. The absorbance at 540 nm of the supernatant in the complement activation reaction system was measured by spectrophotometry as the amount of hemoglobin released was related to the absorbance. 【Results】 The complement activation system was constructed according to the ratio of 3% red blood cell suspension (mixed for 6 people) 1∶anti-Tj^a 1∶complement 2. The repeatability was good (P value>0.05) as different red blood cell mixtures had been used to repeat the detection reaction system. When using 32×, 64× and 128× dilutions of anti-Tj^a mediated complement activation, the deposition of C3b fragments has been detected by flow cytometry at 30 s, 1 min and 2 min, respectively, and MFI peaked at 5 min, 10 min and 30 min, respectively. No obvious hemolysis has been observed within 1.5 h. 【Conclusion】 In vitro model of anti-Tj^a-mediated complement activation demonstrates the speed of complement activation is related to the concentration of antibody. At a certain antibody concentration, the speed of complement activation has been slowed down, and no obvious hemolysis observed.

Objective: To summarize our experience in the diagnosis of internal carotid artery trauma in patients with traumatic optic neuropathy, and to make recommendations for the treatment. Methods: The clinic data of 6 cases who had traumatic optic neuropathy with internal carotid artery trauma and who were admited in Department of Otorhinolaryngology, the Second Affiliated Hospital and Yuying Children′s Hospital of Wenzhou Medical University from Jan. 2013 to Dec. 2015 were analyzed retrospectively. Results: All 6 cases were monocular blindness. Four cases did not undergo nasal endoscopic optic nerve decompression because of the diagnoses of internal carotid artery trauma. One case was diagnosed after nasal endoscopic optic nerve decompression because of fatal bleeding during the operation. One case was diagnosed because of late-onset recurrent epistaxis. Among the 6 cases with internal carotid artery trauma, 3 cases were successfully treated with endovascular interventional treatment (stent embolization was used in one case, Coil embolization was used in two cases), and 3 patients refused treatment. Conclusions The patients with traumatic optic neuropathy have the possibility of severe carotid artery trauma. Endoscopic optic nerve decompression is not suitable for these cases. It should pay more attention to patients with traumatic optic neuropathy. For suspected cases, vascular-enhanced computed tomography screening and digital subtraction angiography should be recommended and patients should be treated by endovascular intervention in a timely manner.
