OBJECTIVE: To analyze the medical records of poisoned children to provide references for the forensic identification of melamine-tainted milk powder poisoning. METHODS: Medical records of six fatal cases of consuming some brand melamine-tainted milk powder were studied, specifically the poisoning symptoms, medical imaging, blood biochemical tests, treatment and prognosis. RESULTS: The major medical problems of these eight-month sick infants were urinary tract obstruction caused by urinary tract calculi. The poisoned infants developed oliguria, anuria and other symptoms, eventually, acute renal failure or other complications leaded to death. The serum BUN and Cr abnormally increased. CONCLUSION By considering the toxicological effects of melamine, it was concluded that the deaths of these sick infants were related to the melamine poisoning.

Objective:To investigate the activated state of TH1/TH2 cytokines and T lymphocytes and to explore the pathogenesis of ankylosing sondylitis.Methods:Cytokine levels of Th1(IFN-?、TNF-?、IL-2)and Th2(IL-10、IL-5、IL-4) in plasma, percentages of CD3 +、CD4 +、CD8 + T cells、B cells(CD19 +) NK cells(CD16 +56 +)and CD3 +HLA-DR +、CD4 +HLA-DR +、CD8 +HLA-DR + T cells in peripheral blood lymphocytes were detected by Flow Cytometry.Results:In patients with AS ,plasma levels of TNF-?、IL-2 were significantly lower than that of healthy controls. IL-10 were significantly higher than that of healthy controls. In AS patients, percentages of CD3 +and CD8 + T cell from peripheral blood lymphocytes were significantly lower than that of healthy controls. Percentages of CD8 +HLA-DR + T cell were significantly lower than that of healthy controls. CD4 +HLA-DR +T cell was significantly highter than that of healthy controls.Conclusion:In patients with AS , lower levels of TNF-?、 IL-2 and higher level IL-10 at plasma indicate an inclination between TH1 and TH2, such as an impaired TH1 cytokine profile and an activated TH2 cytokine profile, especially in TNF-?.

Objective To research the pathogenesis,clinical types and therapeutic effects of acute renal failure.Method All eighty-eight patients with acute renal failure(ARF) treated by hemodialysis were analyzed retrospectively in our hospital for last more than 4 years,and the etiology,clinical types of ARF and the clinical outcome of treatment were summarized.Results ARF patients with pre-renal reasons were 78 41%,single renal cortex and/or medullary disease leading to ARF were 20 45%,post-renal reason was only 1.14%;ARF induced by drugs were 20 45%,the main drugs were aminoglycosides(13/18);mortality rate was 30 97%,but the complete recovery rate was only 37 5%.Conclusion Clinical doctors must be careful observe the patients complications decrasing signs of the blood volume and supplementing blood volume in timely to avoid renal ischemia,these treatment may prevent ARF and kidney lesion induced by drugs,but the prognosis of patients with hemodialysis in ARF is not good.

Objective:To observe the expression of Clusterin in colorectal cancer tissues and study its relationship with the development and progression of colorectal cancer.Methods:Fifty-eight colorectal cancer tissues samples(32 rectal cancer tissues,26 colon carcinoma tissues) of patients with completed clinic data were obtained after surgery from the Affiliated Hospital of Guangdong Medical College.Immunohistochemical staining(SP method) was used to detect the expression of Clusterin in colorectal cancer tissue,adjacent normal tissue of colorectal cancer and normal tissue.Flow cytometry was used to examine the apoptosis of colorectal cancer cells.Results:The expression of Clusterin in colorectal cancer tissues was significantly higher than those in the adjacent tissues of colorectal cancer and normal colorectal tissue(P

ObjectiveTo evaluate the effect of Yuxingchangzhi Decoction on level of norepinephrine (NE) and 5-hydroxyptamin (5-HT) in serum of patients with post-stroke depression. Methods76 patients with post-stroke depression were treated with Yuxingchangzhi Decoction or placebo for 4 weeks. Before and after treatment, all the patients were evaluated with the Hamilton Rating Scale for Depression (HAMD),while the level of NE and 5-HT in serum of patients were measured.ResultsThe total score of HAMD of the patients of Yuxingchangzhi Decoction group was significantly different before and after treatment (P<0.01),while that of the placebo group was not significantly different (P>0.05). The NE and 5-HT level in serum of patients of the Yuxingchangzhi Decoction group were significantly different before and after treatment (P<0.01),but that of the placebo group was not significantly different (P>0.05). ConclusionYuxingchangzhi decoction can raise NE,5-HT level in patients with post-stroke depression and alleviate symptoms of depression significantly.

Objective:To observe and compare the clinical curative effect and safety of topiramate,carbamazepine and sodium valproate on the epilepsy secondary to encephalitis.Methods:80 cases of patients with epilepsy secondary to encephalitis who were treated in our hospital from January 2010 to September 2015 were selected and divided into the topiramate group,carbamazepine group and sodium valproate group,which were treated with topiramate,carbamazepine and sodium valproate respectively.The treatment effect,congnitive scores (including executive function and visual space,name,language,abstract,attention,delayed memory,directional),adverse reaction rate of three groups were compared.Results:The effective rate oftopiramate group was the highest(80.65％,25/31),carbamazepine was the lowest (70.00％,21/30),but there was no significant difference between the three groups (P＞0.05).After treatment,the scores of executive ability and visual spatial,naming,abstraction,attention,orientation,language in topiramate group were significantly higher than those of carbamazepine group and sodium valproate group (P＜0.05);the incidence of adverse reactions of topiramate group was 12.90％,which was significantly lower than that of carbamazepine group (36.67％) and sodium valproate group (29.62％)(P ＜ 0.05).Conclusions:Topiramate,carbamazepine and sodium valproate have equal therapeutic effect on epilepsy secondary to encephalitis,but topiramate had less adverse reactions and best safety.

Objective To investigate the progression of idiopathic epiretinal macular membrane(IEMM) and compare the correlation factors of contrast sensitivity function (CSF) such as visual acuity(VA) and central macular thickness. Design Prospective, case-controlled study.

Objective To study the effect of hepatocyte growth factor (HGF) on hepatocytes after partial hepatectomy in chronic liver injury rats.Methods 30% hepatectomy was performed in rats with cirrhosis induced by CCL 4 and alcohol,and subcutaneously injection of cow HGF into intraabdomen was done with different dosages.Results Small dose (0.16mg?100g -1d -1)of HGF did not stimulate liver regeneration or enhance liver function after partial hepatectomy in cirrhotic rats.Large dose (1.3mg?100g -1d -1) of HGF stimulated liver regeneration and enhanced liver function after partial hepatectomy in cirrhotic rats(P
