AT motif binding factor 1 (ATBF1) gene,is a new tumor suppressor gene,and one of its expression variants by alternative splicing,known as ATBF1-A,can bind to the enhancer AT-rich element of alpha fetoprotein (AFP) and down-regulate the transcription of AFP,which may suppress the development and induce the apoptpsis of some carcinoma cells.In this review,we attempted to analysis the pathway of ATBF1 behaves with other factors and its multiple biological functions;ATBF1 function as a suppressor gene,it was illustrated for the influence on the growth and invasion of breast,prostate or gastric cancer.We also discussed the application of the ATBF1 level function as a cancer predictor,and forecasted the significance to apply ATBF1 for the therapy of cancer.

Objective To explore the association of the Arg64 polymorphism β-3-adrenergic receptor(β3-AR) gene with polycystic ovary syndrome(PCOS)and its characterization with obesity,insulin resistance(IR)，blood pressure (BP), blood lipid spectrum. Methods The polymorphism of the β-3-AR gene was determined in 163 patients with PCOS and 100 controls. Body mass index(BMI), waist to hip circumference ratio(WHR), BP were examined. Blood glucose,blood lipid spectrum,insulin were also measured. Insulin resistance index was calculated. Results The frequency of Arg64 allele in PCOS women was significantly higher than that of controls(0.33 vs 0.13 respectively, P<0.05). Fasting insulin, insulin resistance index, WHR in Arg64 group were significantly higher than those of Trp64 group. The frequency of Arg64 allele was positively correlated with FINS, insulin resistance index, WHR. Conclusion The Arg64 mutation in the β-3-adrenergic receptor(β-3-AR) gene might contribute to development of PCOS and IR.

Objective To evaluate the effect of rosiglitazone on insulin resistance and hyperandrogenism in polycystic ovary syndrome (PCOS) Methods Rosiglitazone was given 4 mg daily to 30 patients with PCOS for 12 weeks Before and after treatment, body mass index(BMI), plasma glucose, insulin, levels insulin resistance index (HOMA IR), blood lipid spectrum, leptin, neuropeptide Y, and sex hormone concentrations and ovulation rate were determined and compared Results After 12 weeks of treatment, basal insulin level decreased from (18?8) to (12?7) mIU/L ( P

Objective To observe the effects of lα-hydroxyvitamin D3 on renal tubular function in the patients with IgA ne phropathy(IgAN) accompanied with proteinuria.Methods Forty-eight eligible patients with IgAN were selected as the IgAN group and divided into the treatment group and control group according to the random number table method,meanwhile 30 healthy adults undergoing healthy physical examination were selected as the normal group.On the routine treatment such as maintaining the double dose of renin-angiotensin system(RAS) blocker,the treatment group took oral l α-hydroxyvitamin D3 capsule (0.5 μg,once a day);the control group continued to adopt the original treatment scheme.The treatment course lasted for 12 weeks.The changes of urinary cystatin C(Cys-C),α1-microglobulin(α1-MG),N-acetyl-β-D-glucosaminidase (NAG),24 h urinary total protein (UTP),blood urea nitrogen (BUN),serum creatinine (Scr),serum calcium (Ca),serum phosphorus (P) and intact parathyroid hormone (iPTH) in two groups were respectively compared between before and after treatment.Results Compared with the normal group,urinary Cys-C,αl-MG and NAG levels in the IgAN group were significantly increased (P＜ 0.01).After 12-week treatment,the levels of Cys-C,α1-MG and NAG were obviously declined compared with that before treatment and in the control group,the differences were statistically significant (P＜ 0.05),meanwhile the UTP level had statistical difference between the two groups after treatment and between before and after treatment in the same group (P＜0.05),but the decrease in the treatment group was more significant than that in the control group(P＜0.05).There was no statistically significant difference in BUN,Scr,Ca,P and iPTH between the two groups before and after treatment(P＞0.05).Conclusion There exists tubulointerstitial injury in IgAN with proteinuria.1α-hydroxyvitamin D3 can significantly decrease urine protein and improves the renal tubular function in the patients with IgAN.

Objective To analyze the epidemiological characteristics of malaria in Hechi City,Guangxi Zhuang Autono?mous Region from 2005 to 2015,so as to provide the evidence for formulating and adjusting measures of malaria elimination. Methods The data of malaria cases in 11 counties of Hechi City from 2005 to 2015 were collected and analyzed by using Micro?soft Office Excel 2003 and SPSS 17.0. Results A total of 160 malaria cases were reported in Hechi City from 2005 to 2015, and the annual average malaria incidence was 3.6 per million. There were 10 local recurrence cases(accounting for 6.25%,10/160)and 150 imported cases(accounting for 93.75%,150/160). For the etiology,Plasmodium vivax accounted for 51.87%(83/160)in these cases,P. falciparum accounted for 34.38%(55/160),P. ovale accounted for 1.25%(2/160),P. malariae account?ed for 5.00%(8/160),and the indeterminate accounted for 7.50%(12/160). During the period of 11 years,the malaria inci?dence first dropped and then rose. There were no local cases after 2009. However,an imported falciparum malaria death case was reported in 2010,a severe imported falciparum malaria case was reported in 2013 and another in 2015. A severe case of ma?ternal?neonatal vivax malaria was reported in 2014. These cases were mainly distributed in 10 counties of Hechi City,with more young male adults who engaged in digging mining. More cases concentrated from April to August. Most of the reported malaria cases were imported,60.00%(96/160)of them returned from Africa and Southeast Asia,and 33.75%(54/160)from other do?mestic provinces. The median of the interval from symptom appearance to diagnosis was 5 d,and there was a significant differ?ence among the above years(c2=33.40,P<0.05). Conclusions Malaria is still an important public health problem in Hechi City,and the appropriate control measures and effective tools should be strengthened for malaria elimination. The key to consoli?date the achievements of malaria control is strengthening the malaria monitoring management of the floating population.

Objective To study the clinical features of acute limited neck motion in children and its differential diagnosis, and to improve doctors' awareness and the early diagnosis of the disease.Methods A total of 420 patients with acute limited neck motion as the chief complaint and atlantoaxial rotary subluxation as the first diagnosis between January 2005 and January 2014 in Nanjing Children's Hospital Affiliated to Nanjing Medical University were enrolled.The clinical manifestations, imaging and consultation data of the 420 patients were retrospectively analyzed.Results There were totally 248 male patients and 172 female patients.The ages ranged from 2 to 14 years old(the mean age was 7.2 years old) ,the course ranged from 2 hours to 2 days.Among 420 patients,353 patients were diagnosed as atlantoaxial rotatory subluxation.Forty-two patients were diagnosed as cervical intervertebral disc calcification.Seven patients were diagnosed as Tourette syndrome.Four patients were diagnosed as intracranial tumors.Three patients were diagnosed as cervical eosinophilic granuloma.Two patients were diagnosed as cervical spinal tuberculosis.Two patients were diagnosed as viral encephalitis.Two patients were diagnosed as benign paroxysmal torticollis.Two patients were diagnosed as Kawasaki disease.One patient was diagnosed as neuroblastoma.One patient was diagnosed as hemophilia A.One patient was diagnosed as drug adverse reaction of metoclopramide.According to Fielding clinical classification,204 patients were type Ⅰ, 122 patients were type Ⅱ,21 patients were type Ⅲ, and 6 patients were type Ⅳ.Conclusions Based on disease distribution of acute limited neck motion in children, atlantoaxial rotatory subluxation seems to be the predominant while non-atlantoaxial rotatory subluxation is not uncommon.Differential diagnoses should be considered to avoid misdiagnosis.For atlantoaxial rotatory subluxation, conservative treatment including continuous mandible occipital belt traction and brace has been proved to be very effective methods.

OBJECTIVE: To compare the effects and medication cost of tenofovir disoproxil and entecavir in the treatment of hepatitis B. METHODS: A total of 300 patients with HBV infection selected from our hospital during Sept. 2015-Sept. 2016 were randomly divided into tenofovir disoproxil group and entecavir group, with 150 cases in each group. Tenofovir disoproxil group was given Tenofovir disoproxil fumarate tablet 300 mg orally, qd. Entecavir group was given Entecavir tablet 0. 5 mg orally, qd, for consecutive 48 weeks. HBV-DNA level, negative conversion rate of HBV-DNA, ALT level and ALT normalization rate were compared between 2 groups before treatment, after 24, 48 weeks of treatment. The medication cost-effectiveness ratio and ADR were compared between 2 groups after 48 weeks of treatment. RESULTS: There were no statistical significances in the level of HBV-DNA between 2 groups before treatment, the level of ALT and ALT normalization rate before treatment, after 24, 48 weeks of treatment (P>0. 05). Compared with entecavir group, the level of HBV-DNA in tenofovir disoproxil group after 24, 48 weeks of treatment was decreased significantly (P<0. 05); the negative rate of HBV-DNA in tenofovir group was slightly higher after 24 weeks of treatment, without statistical significance (P>0. 05); the negative rate of HBV-DNA was slightly increased after 48 weeks of treatment (P<0. 05). Negative conversion rate of HBV-DNA and medication cost-effectiveness ratio of ALT normalization in tenofovir disoproxil group were better than entecavir group (P<0. 05). The incidence of ADR in tenofovir dipivoxil group was lower than entecavir group (P<0. 05). CONCLUSIONS: Tenofovir dipivoxil can effectively treat HBV, and its effects and medication cost are both better than entecavir.

Objective To investigate the curative effect and feasibility of closed reduction with elastic intramedullary nailing and open reduction with Kirschner wire fixation in treatment of obviously displaced radial neck fractures in children. Methods From July 2006 to December 2007, 18 children with types Ⅱ and Ⅲ O' Brien radical neck fractures were admitted to Nanjing Children' s Hospital. Of all, six children received open reduction and fixation with Kirschner wire and six weeks of cast immobilization; the other 12 children received closed reduction and fixation with elastic intramedullary nail and three weeks of cast immobilization. The children were followed up for mean 12 months to investigate postoperative functional recovery of the elbow joint and presence of complications. Results All children achieved excellent clinical outcomes, without excessive radial bone growth, early closure of radial bone marrow, bone bridge formation or ectopic calcification around the joint. According to Tibone and Stoltz' s clinical evaluation methods, closed reduction with elastic intramedullary nailing had less trauma, faster recovery, fewer complications and better cosmesis than traditional open reduction with Kirschner wire fixation for children with obviously displaced radial neck fractures. Conclusion Closed reduction with elastic intramedullary nailing is a better option for obviously displaced radial neck fractures in children.

OBJECTIVEUsing tooth whitening agents (bleaching clip) in vitro and acidic drinks, we conducted a comparative study of the changes in enamel surface morphology, Ca/P content, and hardness.

METHODSTooth whitening glue pieces, cola, and orange juice were used to soak teeth in artificial saliva in vitro. Physiological saline was used as a control treatment. The morphology of the four groups was observed under a scanning electron microscope (SEM) immediately after the teeth were soaked for 7 and 14 d. The changes in Ca/P content and microhardness were analyzed.

RESULTSThe enamel surfaces of the teeth in the three test groups were demineralized. The Ca/P ratio and the average microhardness were significantly lower than those of the control group immediately after the teeth were soaked (P < 0.05). The Ca/P ratio and microhardness gradually increased after 7 d. No significant difference was observed between the control group and the test groups after 14 d (P > 0.05).

CONCLUSIONBleaching agents caused transient demineralization of human enamel, but these agents could induce re-mineralization and repair of enamel over time. Demineralization caused by bleaching covered a relatively normal range compared with acidic drinks and daily drinking.

OBJECTIVETo review the distribution and trends of bacterial culture specimens in Beijing Institute of Ophthalmology.

METHODSA retrospective analysis of the bacterial culture-positive rate, the distribution of gram' s stain, and the distribution and change of isolates was performed on 4705 specimens during a 10-year period (1989- 1998).

RESULTSPositive cultures numbered 1339 of the 4705 specimens, with a positive rate of 28.6%. Gram-positive cocci constituted 55.6% of the total isolates, followed by gram-positive bacilli 13.1% . Gram-negative cocci accounted for 2.8%, and gram-negative bacilli 28.5% . In the positive bacteria cultures, coagulase-negative Staphylococcus (mainly Staphylococcous epidermidis) was the most common isolate (25.3%), and followed by Pseudomonas 18.8%, Micrococcus 11.7%, Cotynbaccterium 10.1%, and Staphylococcus aureus 8.2% . During the 10-year period, the overall frequency of gram-positive cocci appeared to increase with time while the frequency of gram-negative bacilli decreased.

CONCLUSIONSGram-positive cocci and gram-negative bacilli are still the predominant pathogens of ocular infection in northern China. The frequency of the former increases annually whereas that of the latter decreases. It is important to comprehend the distribution and trends of ocular pathogenic bacteria for the diagnosis, prevention and treatment of bacterial infectious ocular disease.
