1.Clinical manifestations and advances in hereditary research of alternating hemiplegia of childhood
International Journal of Pediatrics 2014;41(3):229-232
Alternating hemiplegia of childhood(AHC) is a hereditary disease characterized by hemiplegia spells,abnormal eye movements,dystonia and cognitive impairment.There are three phases of the disease.Each phase has its unique clinical symptoms:phase 1-abnormal eye movements and dystonia;phase 2-hemiplegia spells; phase 3-permanent cognitive impairment.The severity of cognitive impairment depends on the time of onset of hemiplegia spells:the earlier the onset is,the worse outcome will be.No effective treatment has been established.Thetreatments currently include:avoiding predisposing factors and taking drugs such as flunarizine to prevent hemiplegia attacks,in the inter-ictal stage;and sedation during hemiplegia attacks.According to the latest research,AHC is caused by the de novo mutation of gene ATP1A3.

International Eye Science 2015;(5):832-835
?AlM:To evaluate the effect and safety of 1. 8mm coaxial microincision phacoemulsification - trabeculetomy with ultra-thin intraocular lens ( lOL ) implants for treating glaucoma complicated with cataract, and to compare with the traditional 3. 0mm small phacoemulsification-trabeculetomy with foldable lOL implantion.
?METHODS: ln this prospective study, 36 patients ( 36 eyes) with glaucoma and cataract in lnner Mongolia Autonomous Regian People’s Hospital were collected and randomly divided into 2 groups. For the small incision group: 18 cases ( 18 eyes ) underwent 3. 0mm coaxial incision phacoemulsification-trabeculetomy with foldable lOL implantion; ln th microincision group: 18 cases ( 18 eyes ) underwent 1. 8mm microincision phacoemulsification-trabeculetomy with ultra-thin lOL implantion. The two groups were recorded for 1wk, 1 and 3mo of visual acuity, corneal endothelial cell density, surgically induced astigmatism, intraocular pressure ( lOP ) , filtering bleb and complications. Pearson’s Chi-square test ande t-test were used to determine differences between the two groups.
?RESULTS:At 1wk postoperatively, visual acuity in the microincision group was better than that of small incision group, the difference was statistically significant ( P<0. 05). At 1 and 3mo, the difference in corrected visual acuity between the 2 groups had no significant difference (P>0. 05). At 1wk, 1 and 3mo, there was a significant different between the 2 groups in surgically induced astigmetism (P<0. 05). At 1wk postoperatively, there was a significant difference in corneal endothelial cells density between 2 groups (P<0. 05). But there were no significant difference at 1 and 3mo ( P > 0. 05 ). lOP reduced after surgy ( microincision group: 15. 26 ±3. 12mmHg, small incision group: 14. 57±2. 86mmHg), there was no significant difference between the 2 groups (P>0.05). There was no significant different between the 2 groups in blebs (P>0. 05). Neither iris injury, posterior capsule rupture nor anterior chamber bleeding complications was found in any groups.
?CONCLUSlON: TBy compared with traditional 3. 0mm coaxial small incision phacoemulsification -trabeculectomy with foldable lOL implantion, 1. 8mm microincision phacoemulsification-trabeculectomy withe ultra- thin lOL implantion can effectively reduce the astigmatism operation. This operation is safe, effective, convenient surgy for treating cataract and glaucoma.

5.Comparative analysis of clinical characteristics and outcome of neonates transferred by different ways
Chinese Journal of Emergency Medicine 2011;20(5):477-480
Objective To explore the clinical characteristics and outcome of neonates transferred by different ways. Method A total of 1 027 neonates transferred to neonatal intensive care unit(NICU)of our hospital from July 2009 to July 2010 were analyzed prospectively. They were divided into three groups: twoway transport(TWT),hospital-aided one-way transport(HAT)and self-help one-way transport(SHT).The conditions at admission and discharge and pre-hospital care of the neonates were compared between the groups. The data were statistically analyzed with square tests, variance analysis and Mann Whitney U test. Results The median ages of TWT,HAT, and SHT groups at admission were 0.46 d,0.33 d and 5 d respectively. The TWT and HAT neonates had smaller gestational age and birth weight than SHT ones, had more severe conditions and cost more,and the differences were significant(P<0.05).Significant differences existed in all emergency treatment except in warming measures(x2=96.855~103.863,P<0.05).The cure percentage at discharge was the highest in SHT group,and differences in treatment results of three groups were significant(Z=-1.987 to-5.347,P<0.05).Conclusions The TWT and HAT neonates have smaller gestational age,ages at admission and birth weight than SHT ones,have more severe conditions,cost more and lower cure percentage at discharge than SHT ones.
6.Iodine intake and thyroid function during pregnancy
Chinese Journal of Endemiology 2016;35(3):161-165
Iodine is an essential micronutrient for pregnant women,which affects thyroid function of pregnant women and fetus,and thus influences the intellectual development of offspring.Severe iodine deficiency could lead to overt hypothyroidism and fetal cretinism.In the areas implemented the universal salt iodization (USI) program,mild to moderate iodine deficiency and iodine excess may coexist during pregnancy.Iodine deficiency could lead to hypothyroxinemia in pregnant women.Iodine more than adequate and iodine excess could increase the prevalence of subclinical hypothyroidism.The effect of iodine supplementation on thyroid function in pregnant women with mild to moderate iodine deficiency may result in different conclusion.Therefore,it is important to maintain optimal urinary iodine concentration to prevent thyroid dysfunction.
7.Effect of Gingko Flavonoids on Cardiac Function and Contents of SOD and MDA in Myocardial Tissue in Rats with Heart Failure
China Pharmacist 2014;(10):1637-1639
Objective:To explore the effect of gingko flavonoids on the content of SOD and MDA and cardiac function in the rats with heart failure. Methods:Totally 40 male Sprague-Dawley rats were randomly divided into 5 groups by random number table meth-od, namely the blank group, the model group, low-dose gingko flavonoids group, high-dose gingko flavonoids group and metoprolol group. Except the blank group, all the other groups were subcutaneously injected 300 mg·kg-1 isopropyl adrenaline for two days to make the heart failure model. After that, metoprolol group was given metoprolol 20 mg·kg-1 ·d-1 , the ginkgo flavonoids group was given 250 or 500 mg·kg-1 ·d-1 ginkgo flavonoids extract, the other groups were given physiological saline with the same volume, and the treatment course was 8 weeks. After the treatment, cardiac function indices ( IVST, LVPWT, LVEDD, LVESD and LVEF) , SOD and MDA levels in cardiac muscle tissue and the pathological integral, and myocardial pathologic morphology characteristics were deter-mined. Results:LVEDD and LVESD of the two ginkgo flavonoids groups and metoprolol group were obviously improved compared with those of the model group, while LVEF, IVST and LVPWT were significantly decreased (P<0. 05), showing that the cardiac function was improved after the treatment. The levels of SOD were raised, while MDA and the pathological integral were decreased significantly in the two ginkgo flavonoids groups compared with those of the model group (P<0. 05), with a dose-dependant relationship. Conclu-sion:Ginkgo flavonoids have certain protective effect in heart failure rats, and the mechanism may be related to reducing the level of lipid peroxidation and improving the body antioxidant enzyme activity.
8.Effect of Hepatocyte Growth Factor/Scatter Factor on Apoptosis of Colorectal Cancer Cells Induced with Curcumin
Chinese Journal of Bases and Clinics in General Surgery 2004;0(01):-
Objective To explore the effect of hepatocyte growth factor/scatter factor (HGF/SF) on apoptosis of colorectal cancer cells induced with curcumin. Methods MTT assay was used to evaluate the cytotoxicity of curcumin to colorectal cancer cells. Flow cytometry was used to detect the anti-apoptosis effect of HGF. Results Flow cytometry showed only 64 ?g/ml curcumin could play the proliferation-inhibiting role in Caco-2 cells leading to their apoptosis; at the same time, different concentrations of HGF could antagonize this inhibitory effect resulting in the decrease of apoptosis, but HGF worked without a concentration-dependent manner. The study on MAPK pathway showed that the protective effect of HGF on the apoptosis of Caco-2 cells was not influenced by inhibiting p42/p44 MAPK and p38 MAPK pathway. Conclusion HGF/SF antagonizes the apoptosis of Caco-2 cells induced with curcumin, but MAPK signaling pathway might not participate in this process.
9.Reduced expression of ADAM8 and its role in breast cancer
Journal of Endocrine Surgery 2012;06(5):294-297,306
ObjectiveTo investigate the expression of a disintegrin-like and metalloproteinase 8 ( ADAM8 ) in breast cancer and in normal breast tissues and its negative regulation role in tumorigenesis and progress of breast cancer.MethodsThe expression of ADAM8 in breast cancer and normal breast tissues was detected by immunohistochemistry (IHC),qRT-PCR,and Western blot.The relation between ADAM8 expression and the clinicopathological parameters of breast cancer patients was analyzed.ResultsADAM8 was expressed in breast cancer and normal breast tissues.The expression of ADAM8 mRNA and protein was significantly lower in breast cancer than in normal breast tissues (qRT-PCR:P =0.015,IHC:P =0.044,Western blot:P =0.000).The expression rate of ADAM8 was related to lymph node metastasis,tumor stage and tumor size,although the difference had no statistical significance.IHC results showed that ADAM8 expression level was lower in stage Ⅲ + Ⅳthan in stage Ⅰ + Ⅱ ( P =0.574 ).qRT-PCR showed ADAM8 mRNA expression was lower in stage Ⅱb + Ⅲ than in stage Ⅰ + Ⅱ a ( P =0.247).ADAM8 expression was lower in the breast cancer tissues with lymph node metastasis than in those without lymph node metastasis (P =0.560 by IHC and P =0.592 by qRT-PCR).ADAM8 expression was lower in tumors whose size > 2 cm than in tumors whose size ≤ 2 cm,however,the difference had no statistical significance ( P > 0.05 ).ConclusionsADAM8 is significantly lower-expressed in breast cancer than in normal breast tissues,which is associated with clinical stages and lymph node metastasis.The reduced expression of ADAM8 may play a role in the pathogenesis and progress of breast cancer.
