AIM:To investigate the serum antibody of aquaporin 4 ( AQP4 - Ab ) in positive expression rate and the significance in patients with neuritis.
●METHODS: A total of 98 cases ( 128 eyes ) of patients with optic neuritis were studied to detect the patient′s serum AQP4-Ab positive rate of antinuclear antibodies ( ANAs) from Jan. 2012 to Dec. 2015 in ophthalmology center of our hospital. According to the expression of AQP4 - Ab group, the best corrected visual acuity between the two groups, peripapillary nerve fiber layer thickness (pRNFL), the volume of the macula, macular RNFL ( mRNFL ) , macular core layer volume ( mlNL ) measurement were compared.
●RESULTS:Ninety-eight patients (128 eyes) with optic neuritis cases diagnosed through examination revealed AQP4-Ab positive in 22 patients ( 22%) , negative in 76 patients ( 78%) , ANAs positive in 21 patients ( 21%) , negative 77 patients ( 79%) . Optic neuritis patients with serum AQP4 - Ab positive rate and ANAs positive significant correlation ( r = 0. 707, P < 0. 05 ). After examination revealed AQP4-Ab patients and negative-positive patients with best corrected visual acuity difference was not statistically significance (P>0. 05). After inspection found pRNFL, macular volume measured value AQP4 - Ab positive patients were significantly less than the negative patients, the differences were statistically significant (P<0. 05). AQP4-Ab positive patients and negative patients the mRNFL, mlNL measured values were not significantly different (P>0. 05).
●CONCLUSION:AQP4-Ab and ANAs expression in optic neuritis patients is a significant correlation. AQP4-Ab positive patients with optic neuritis pRNFL thinning of macular volume are decreased compared with negative patients.

It is held by some of the researches that the "16 collaterals" is composed of the "15 collaterals" and "the major collateral of stomach". And it is included into the textbook that Xuli, the major collateral of stomach, is the pulsation point at the cardiac region. Xuli is often explained as the empty portion of the human body by many researches. Through analysis and summarization of the related theory of the major collateral of stomach, the above mentioned opinion is discussed. And the understanding on the major collateral of stomach is deepened. As a result, it is concluded that count the major collateral of stomach into the 16 collaterals together with the 15 collaterals is inadvisable. The real pulsation point at the cardiac region locates under the left breast. And the real meaning of Xuli is "extending in all directions".

Objective:
To assess the exposure levels of lead, cadmium, mercury, arsenic and aluminum in the diets of residents in Henan Province, so as to provide the basis for strengthening food safety supervision.
Methods:
Six sampling points were selected using stratified random sampling method in Henan Province, including Hebi City, Xiangfu District of Kaifeng City, Jianxi District of Luoyang City, Yuzhou City, Baofeng County and Tanghe County. Food samples were collected and processed into mixed samples of 12 major food categories. The levels of lead, cadmium, mercury, arsenic and aluminum in the samples were measured using inductively coupled plasma mass spectrometry (ICP-MS). Dietary consumption information in Henan Province was collected. The dietary exposure risks of lead, cadmium, mercury, arsenic and aluminum were analyzed using the point estimation method and distribution point estimation method, based on the health guidance values of the Joint FAO/WHO Expert Committee on Food Additives and the margin of exposure (MOE) as the assessment criteria.
Results:
The dietary exposure level of lead among residents in Henan Province was 41.89 μg/d, which was equivalent to 18.62% of its provisional tolerable weekly intake (PTWI), with cereals and vegetables being the main sources; the MOE values of lead among residents aged 2 to <7 years and 7 to <13 years were both less than 1. The dietary exposure level of cadmium was 10.79 μg/d, which was equivalent to 20.55% of the provisional monthly tolerable intake, with cereals and vegetables being the main sources. The dietary exposure level of total mercury was 0.45 μg/d, which was equivalent to 1.25% of its PTWI, with cereals, vegetables, and water and beverage categories being the main sources; the dietary exposure level of methylmercury was 0.04 μg/d, which was equivalent to 0.28% of its PTWI, and it was entirely derived from aquatic products. The dietary exposure level of total arsenic was 26.65 μg/d, which was equivalent to 0.89% of the daily allowable intake, with cereals and vegetables being the main sources; the dietary exposure level of inorganic arsenic was 8.41 μg/d, which was equivalent to 6.23% of its PTWI, with an MOE value of 22.47. The dietary exposure level of aluminum was 8.27 mg/d, which was equivalent to 45.94% of its PTWI, with cereals and tubers being the main sources; the P90 and P97.5 of dietary aluminum exposure among residents aged 2 to <7 years and 7 to <13 years were both greater than PTWI.
Conclusion
The overall dietary exposure risks of lead, cadmium, mercury, arsenic and aluminum among residents in Henan Province are relatively low.

To study the effect of Wansheng Huafeng Dan (WSHFD) and mercuric chloride on renal mercury (Hg) extraction transporters (Oat1, Oct2), renal mercury excretion transporters (Mrp4, Mate2K), renal mercury accumulation and kidney injury molecule-1 (Kim-1). The ancient prescription of WSHFD containing 10-fold Hg caused much lower renal mercury accumulation and renal toxicity than HgCl2 in rats, with less effect on renal transporters than HgCl2. The above indicators had no significant difference in WSHFDO, WSHFD2 and WSHFD3 groups, indicating no effect of WSHFD with reduced or no cinnabar.

The effects of streptozotocin-induced diabetes or long-term glyburide administration on mRNA levels of components of ATP-sensitive potassium channel(SUR1,SUR2,Kir6.2)in rat brain were observed. Streptozotocin-induced diabetes itself did not affect the mRNA levels of SUR1,SUR2,and Kir6.2 in the brain, and glyburide-treatment increased the Kir6.2 mRNA level in brain by 23% in non-diabetic rats than those in normal control but did not change SUR1 and SUR2 levels.The effects of glyburide on SUR1,SUR2 and Kit6.2 mRNA levels did not manifest in brain of diabetic rats.

OBJECTIVETo investigate the effect of parasympathectomy on secretion of submandibular glands and the feasibility of treatment for xerostomia in rats.
METHODSTwenty Sprague-Dawley male rats weighing 200 - 300 g were randomly divided into the experimental group (n = 12), in which the right chorda-lingual nerve was cut, and the control group (n = 8). The secretion of submandibular gland was measured for 5 min by Schirmer test for both groups.
RESULTSThe stimulated saliva flow rate decreased on 1st, 12th and 24th week after denervation in the right operated submandibular glands (P < 0.05). No difference in secretion was found between the left non-operated glands and the control group. Comparing with the left non-operated gland and the control gland, the saliva flow rate at rest in the right operated submandibular gland increased on the 1st, 12th and 24th week (P < 0.05).
CONCLUSIONSAfter parasympathectomy of rat submandibular glands, the saliva flow rate at rest increased in the denervated gland, which suggests that parasympathectomy of submandibular gland might be used as a therapy for xerostomia.
