Objective To evaluate the neuroprotective effect and safety of neonatal hypoxic-ischemic encephalopathy(HIE)treated with recombinant human erythropoietin(rhEPO).Methods Fifty-three neonates with HIE were randomly divided into rhEPO treated group(n=29) with the dosage of 300 U/(kg?time),three times a week for 2 weeks and control group(n=24)without rhEPO.All supportive measures were same between 2 groups.Neurological scoring was evaluated at d3,d5 and d7 Neonatal behavioral neurological assessment(NBNA) was evaluated at d7,d14 and d28.The neurodevelopment quote was evaluated at age of 3 and 6 months.Blood pressure,liver and renal function,blood electrolytes and blood hemoglobin,platelet and reticular red blood cell count were monitored before and after treatment in all infants.Results The neurological scoring between two groups had no difference at d3.The significant difference was found at d7(P0.05).Conclusions Teraphy with rhEPO on neonatal HIE infants can promote neurological recovery,and there is no serious side effect with rhEPO treatment.

AIM: To investigate the feasibility and clinical effect of punctoplasty by using trabeculectomy punch combined with a novel RS tube for the treatment of punctal stenosis.METHODS: Totally 39 patients (39 eyes) with punctual stenosis were selected from October 2013 to October 2015 in the Second People`s Hospital of Foshan.All patients underwent punctoplasty by using trabeculectomy punch combined with a novel RS tube.These tubes were removed at 3mo after operation.A follow-up of 6mo was taken for final analysis.The fluorescein dye disappearance test score was recorded before the operation and at 1,3 and 6mo after the extubation.The curative effect of the operation at 6mo after the extubation was assess.RESULTS: Fluorescein dye disappearance test: the scores at 1,3 and 6mo after the extubation all decreased compared with the preoperative ones.The difference was statistically significant(P<0.05).At the last following up, 35 eyes (90%) were cured completely, 4 eyes (10%) were improved significantly, no patients recurred.Effective rate was 100%.No serious intraoperative and postoperative complications happened.CONCLUSION: Punctoplasty by using trabeculectomy punch combined with novel RS tubes is a safe and effective method for the punctul stenosis, which is easy to perform, with high success rate.

ObjectiveTo observe the inhibition effect of docetaxel-loaded lipid microbubbles (DLLM) combined with ultrasound targeted microbubbles destruction (UTMD) on microvessel in rabbit VX2 liver tumor models.MethodsSixty rabbits were randomly divided into 6 groups (n= 10),i.e.Doc group (used docetaxel only),DLLM group (used docetaxel-loaded lipid microbubbles),Doc+US group (used docetaxel combined with ultrasound positioning irradiation),PLM+US group (used microbubbles combined with ultrasound positioning irradiation),DLLM+US group (used docetaxel-loaded lipid microbubbles combined with ultrasound positioning irradiation) and control group.The expression of CD34 and VEGF and microvessel density (MVD) were compared among different groups.ResultsAfter treatment,the expression of CD34 in DLLM+US group was lower,the MVD of DLLM+US group was markedly lower than that of the other groups (P＜0.01),while the expression of VEGF in this group was the lowest among all 6 groups (P＜ 0.01).ConclusionDLLM combined with UTMD can inhibit the generation of microvessels in rabbit VX2 liver tumor,thus inhibit the growth of the tumor.

Objective In our previous study,we established DNA microarray technology for identification of medical viruses on genus levels and arboviruses on species levels.In this study,we employed these microarrays to determine the pathogen of newly isolated unknown virus in July,2006 from pig brain in Shanxi province.Methods The pathogen isolated from pig brains were inoculated in BHK21 cells.After CPE were observed,the supernatants were collected and RNA was extracted.After reverse transcription and random PCR amplification,the labeled nucleic acids were hybridized with DNA microarrays.Results The hybridization results with medical viruses DNA microarray indicated that the unknown virus belonged to Flavivirus.Combined with epidemiological investigation,we presumed that it might be a kind of arbovirus. Then the labeled specimen were further hybridized with arbovirus DNA microarray and the results confirmed that it was Japanese encephalitis virus(JBV).This coincided with PCR and sequencing analysis.Conclusions The DNA microarray we established previously could be employed to identify unknown viruses.This method provides a new method for determining new viral pathogens.

The research on endocrine disrupters has become one of the key directions in the field of environmental medical science. Nonylphenol ethoxylates (NPEs) are widely used in industry and family washing as one of the non-ionic surfactants. NPEs can be degraded biologically to nonylphenol (NP), whose estrogenic effects or toxicity may do harm to the reproductive systems of male fish, amphibians and mammals. Thus it is an urgent affair to develop perfect assays, evaluate the harm of these chemicals to human beings, find the exact mechanism of action and restrict the use of NPEs.

Spleen diarrhea is one of the common diarrhea diseases. Because it has long course, lingering and difficult to cure, and easy to occur, it is difficult to treat. Professor WANG Dao-kun believes that spleen-stomach yang deficiency, disorder of qi movement, and dampness and internal stagnation are the common etiology and pathogenesis of spleen diarrhea. The treatment should be warming middle Jiao and tonifying spleen, regulating qi, and promoting diarrhea. Professor WANG has prepared modified Wenzhong Zhixie Decoction for the treatment of spleen diuresis. This article expounded Professor WANG's experience in treating spleen diarrhea with Wenzhong Zhixie Decoction.

Objective To explore the correlation between serum hepatitis B virus (HBV) X antigen/antibody (HBxAg-wild/HBxAb-wild,and HBxAg-mutant/HBxAb-mutant) and the disease progression in patients with chronic HBV infection.Methods A direct enzyme immunosorbent asssay (ELISA) was performed to detect HBxAb using recombinant antigen,and a double antibody sandwich ELISA assay to detect HBxAg using monoclonal antibody and specific rabbit polyclonal antibody.HBxAg-wild/HBxAb-wild and HBxAg-mutant/HBxAb-mutant were tested in sera from cases at different stages of chronic HBV infection.A chi-square test was employed to examine statistical significance.Results The positive rates of HBxAg-wild and HBxAg-mutant in the chronic asymptomatic HBV carriers,chronic hepatitis,hepatitis B-related cirrhosis and liver cancer were 6.2％ (2/32),10.7％ (3/28),28.6％ (6/21),43.6％ (17/39) and 3.1％ (1/32),10.7％ (3/28),33.3％ (7/21),48.7％ (19/39),respectively.The positive rates of HBxAb-wild and HBxAb-mutant in the above mentioned groups were 6.2％ (2/32),21.4％ (6/28),38.1％ (8/21),53.8％ (21/39)and 6.2％ (2/32),25.0％ (7/28),42.9％ (9/21),61.5％ (24/39) respectively.The positive rates of HBxAg-wild and HBxAg-mutant were not significantly different among the above groups (x2 =0.871,0.780,0.565 and 0.317,respectively; all P＞0.05) ; The positive rates of HBxAb-wild and HBxAb-mutant were also similar among all the groups (x2 =0.780,0.709,0.580 and 0.210,respectively; all P＞0.05).The positive rates of HBxAg-wild,HBxAb-wild,HBxAg-mutant,HBxAb-mutant in patients with low viral loads (HBV DNA＜1 × 104 copy/mL) were 36.5％ (23/63),44.4％ (28/63),42.9％ (27/63) and 54.0％ (34/63),respectively,those in patients with high viral loads (HBVDNA≥1×104 copy/mL) were 8.8％ (5/57),15.8％ (9/57),5.3％ (3/57) and 14.0％ (8/57),respectively.The positive rates of HBxAg and HBxAb were significantly higher in cases with low viral loads than those with high viral loads (x2 =12.869,11.522,22.556 and 20.976,respectively; all P＜0.05).The positive rates of HBxAg-wild,HBxAb-wild,HBxAg-mutant,HBxAb-mutant in the HBeAg positive group were 21.7％ (18/83),30.1％ (25/83),22.9％ (19/83) and 32.5％ (27/83),respectively,while those in the HBeAg negative group were 27.0％ (10/37),32.4％ (12/37),29.7％ (11/37) and 40.5％ (15/37),respectively.No significant difference of HBxAg/HBxAb positive rates between HBeAg positive group and HBeAg negative group was noticed (x2 =0.408,0.064,0.638 and 0.722,respectively; all P＞0.05).Conclusions The antigenicity and specificity of HBV X protein remains similar after the occurrence of A1762T/G1764A double mutant in X gene.It is also found that the positive rates of HBxAg and HBxAb increase with disease progression.HBxAg/HBxAb might be promoting factors for tumorigenesis in chronic HBV infection.HBxAg and HBxAb might have negative influence on HBV replication.

?AIM:To analyze the clinical features of Terrien marginal degeneration ( TMD) .?METHODS:Fifty-six patients(90 eyes) admitted in our hospital from January 2013 to January 2015 were selected as observation group.At the same period, 56 healthy (88 eyes) for corneal examination were as control group to analyze the clinical features of TMD.

Purpose To investigate the relations of THEM4/Akt expression and extracellular matrix deposit in kidney of diabetic mice. Methods Diabetic mice models were successfully established by intraperitoneally injected STZ. Both normal control mice and diabetic mice were raised for 8 week until they were sacrificed. Western blot, immunohistochemistry and realtime PCR were used to detect the expression of THEM4, phospho-Akt (Ser 473), TGF-β1, a-SMA, Col Ш, FN protein and THEM4 mRNA in the kidneys of normal mice and diabetic mice. Results Compared to normal control mice, THEM4 expression decreased by 37.7％ followed by 3.66, 1.29 2.33, 1.99 and 2.82 times increased of phospho-Akt (Ser473), TGF-β1, a-SMA, Col Ш and FN in kidney of diabetes mellitus. Extracellular matrix accumulation was found in renal interstitial region of diabetic mice. Conclusion The decreased THEM4 might cause extracellular matrix deposit in kidney of diabetic mice by upregulating the phosphorylation of Akt and TGF-β1, α-SMA expression in diabetic mice.

Objective To understand the characteristic of sexual behavior and their associated factors among male and female partners of men who have sex with men in Anhui province. Methods Cross-sectional studies were conducted among MSM in Hefei, Wuhu and Liuan in Anhui province. MSM were recruited through “snowball sampling” and “internet-based recruiting”, and eligible participant received an anonymous survey. Multivariate Logistic regression analysis model was used to identify risk factors associated with having sex with women in the last 6 months among MSM. Results Of the 1 200 MSM interviewed, 78.3% had anal sex with men, and 20.9% had vaginal intercourse with women, and 16.5% had sexual intercourse with both men and women in the past 6 months. Less MSM reported using condom every time with women (29.9%) in the past 6 months than with men (53.0%), and less reported using condom with women (52.2%) during the last sexual intercourse than with men(79.6%) (all P<0.05). The results of mutivariate Logistic regression analysis showed that MSM who were married(including currently married/cohabitating/divorced/widowed), lived more than 2 years in the surveyed city, and had commercial sex with men were more likely to have sex with women. Conclusions There was a high proportion of bisexual behavior and low rate of condom use among MSM. It should strengthen the sexual health education, risk perception education and behavioral intervention among MSM.
