DAZL, a member of the DAZ family, plays a key role in human spermatogenesis. It regulates the promoter via genetic modification, especially DNA methylation, promoting the transcription of DAZL. Besides, the relation of DAZL SNPs with male infertility has been a hot spot of research for many years. It is deduced that local and ethnic factors may be associated with the failure of spermatogenesis. This article presents an overview on the results of recent studies, changes in the DNA methylation of DAZL in spermatogenesis, and the association of DAZL SNPs with male infertility, aiming to provide a new theoretical basis and clinical strategy for the treatment of male infertility.

Objective To study on the effectiveness of endoscopic ultrasonography(EUS)in detec- ting insulinoma preoperatively.Methods Fifteen patients with clinical and biochemical signs of insulinoma were examined by EUS using a radial-scanning ultrasound endoscope and abdominal ultrasonography,CT, DSA prior to surgery.The outcome was evaluated on the basis of surgery and examination of the resected specimens.Results Fifteen patients with 16 lesions of insulinoma were identified by surgery and pathology. The aceuraey of diagnosis with EUS was 13/15(86.7%),and that with B-US,CT,DSA was 3/15(20%), 5/15(33.3%),9/14(64.3%)respectively.In the 14 lesions identified by EUS,10 lesions were depicted to be hypoechogenic,1 lesion was isoechogenic and 3 lesions were hyperechogenie.All 14 lesions were well demarcated and surrounded by normal pancreatic tissue.The minimum size of the lesion visualized by EUS was 0.5cm.Ten lesions were correctly detected by EUS with size of 0.5～2.0cm.EUS missed diagnosis in 2 lesions not for their small size.EUS falsely indicated a 10mm lesion from two lesions inside the head of pancreas.One lesion outside the pancreatic tail and one lesion in the pancreatic head were missed by EUS in another case.Conclusion EUS is superior in assessing the location of pancreatic insulinoma than other ima- ging methods such as B-US,CT,DSA.

The development of printing ink is a challenge for binder jetting 3D printed preparations, which directly determines the quality of the printed product. This study adopted a 2³ full-factor Design of Experiment (DoE) with three central points to optimize the printing ink composition of levetiracetam 3D printed dispersible tablet based on the concept of Quality by Design. Firstly, using polyvinyl pyrrolidone K30, glycerin and polysorbate 20 as independent variables based on 40% (v/v) isopropanol aqueous solution, and weight variation, hardness, friability and dispersion uniformity of the printed tablets were used as dependent variables. Then obtained the design space of the printing ink prescription by DoE model analysis, and the response optimizer was used to obtain the optimal printing ink prescription: isopropanol aqueous solution containing 0.1% (w/w) polyvinyl pyrrolidone K30 and 4.0% (w/w) glycerin. The jetting mechanism and wettability of the printing ink were analyzed, and different strengths of personalized 3D printed tablets were prepared and characterized, which verified the rationality of the printing ink formulation. This study provided a reference for the development of printing ink for binder jetting 3D printed preparations.

Objective To evaluate the relationship between asthma and rhinitis in children.Methods One hundred and thirty children with rhinitis were divided into two groups.Among them,60 displayed rhinitis alone and 70 displayed rhinitis associated asthma.The following parameters were analyzed between two groups: age,sex,history of eczema,familial history of smoking,familial history of asthma,sensitization to allergens,level of total serum IgE,blood eosinophil count.Logistic regression analysis was used to analyze the effect of covariates on risk of rhinitis or asthma.Results History of bronchiolitis,familial history of asthma,maternal asthma and sensitization to allergens h_1(greer labs inc),d_2(dermatophagoides farinae) were significantly more frequent in asthmatic subjects.In these patients,the total serum IgE and eosinophil count were higher.Logistic regression analysis showed that a high eosinophil count and total serum IgE significantly increased the risk of developing asthma in patients with rhinitis.Conclusions In subjects with rhinitis,the occurrence of asthma is related to history of bronchiolitis,familial history of asthma,atopy,total serum IgE levels and blood eosinophilia.In rhinitis subjects,these parameters will be taken into account to manage underlying asthma.

Objective To explore the clinical characteristics and treatment of Caroli′s disease in children.Methods The clinical data,laboratory examination and radiological feature of 8 children with Caroli′s disease between Feb.1998 and Dec.2007 were analyzed retrospectively.All children underwent CT and abdominal ultrasonogram.Results Five cases of the 8 children were male and 3 cases were female.The mean age was 6.3 years old.The cases′ history were from 5 days to 4 months.The clinical symptoms showed that 3 cases had hematemesis,5 cases had hepatosplenomegaly,and 1 case had fever and turbid urine.Of the total 8 cases,5 cases were hepatic fibrosis and liver cirrhosis and hepatosplenomegaly,3 cases were portal hypertension,and 1 case had cholangitis.The other 3 cases were simple types.One case had infantile polycystic kidney disease.Laboratory analysis revealed 2 cases had dysfunction of liver and 1 dysfunction of renal.The imaging characteristics showed multiplied irregular dilatation of the intrahepatic bile ducts in enlarged liver,with central dot sign on CT scan.One case presented enlarged gastroesophageal vein.The 8 cases undertook conservative treatment,with no surgery.Conclusions The symptoms of Caroli′s disease are highly variable.Caroli′s disease should be focused especially on children with abdominal pain and hepatomegaly.CT is important for diagnosis of Caroli′s disease at earlier stage.The disease can be conservatively treated,and(or) surgically operated.

The paper aimed to study the residue decline dynamic and standards for safety utilization of carbendazim in roots, stems, leaves of Anoectochilus roxburghii and in growth media. Samples extracted with methanol were purified by liquid-liquid extraction and analysed by HPLC. The results showed that average rate of recovery was 82.9% - 95.7% and RSD were 2.0% - 6.3% with add of carbendazim in respectively diverse concentration, which meets inspection requirement of pesticide residue. Two kinds of dosages of carbendazim were treated, varying from recommended dosage (1.0 kg x hm(-2)) to 1.5 times recommended dosage (1.5 kg x hm(-2)). Results of two years test showed that the half-life period of carbendazim were 7.01 - 8.51 d in the growth media of A. roxburghii, 3.58 - 4.27 d in stems and 3.50 - 3.91 d in leaves, 4.93 - 5.71 d in roots. Providing max recommended residue of carbendazim in the cultivation of A. roxburghii is 0.5 mg x kg(-1), sprayed 4 times a year with the dosage of 1.0 kg x hm(-2), 28 days is proposed for the safety interval of the last pesticide application's and harvest's date.

Objective To investigate the relationship between adiponectin and the first-phase of pancreatic P-cell insulin secretion in subjects with different statuses of glucose tolerance. Methods Thirty-seven patients with newly diagnosed type 2 diabetes mellitus (DM) , 30 patients with abnormal glucose tolerance (IGR) , and 40 normal control subjects (NGT) underwent intravenous glucose tolerance test (IVGTT). Fasting adiponectin and proinsulin (PI) was assayed by EL1SA. Fasting free fatty acid ( FFA) was measured by colorimetry. Insulin area under the curve ( AUC ) , incremental AUC (iAUC) from 0 min to 10 min, AIR3-5, homeostasis model assessment for insnlin resistance (HOMA-IR) , and for β cell function ( HOMA-p) were calculated. The relationship between adiponectin and AUC, iAUC, AIR3-5, proinsulin, FFA, and HOMA-IR was explored. Results (1) The levels of AUC, iAUC, AIR3-5, and adiponectin in DM group and IGR group were significantly lower than those in NGT group (P<0.05), reduced in DM group than those in IGR group(P<0.05). (2) The levels of PI in DM group and IGR group were significantly higher than that in NGT (P<0.05). (3) Adiponectin was positively correlated with HOMA-p,AUC,iAUC,AIR3-5, and HDL-C,while negatively correlated with proinsulin, HOMA-IR, and LDL-C. (4) Proinsulin was positively correlated with HOMA-IR. (5 ) Multiple regression stepwise analysis showed that adiponectin was independently associated with AUC. Conclusions Adiponectin was an independent factor affecting the first phase of pancreatic p-cell insulin secretion. Low adiponectin level could predict the dysfunction of the first phase pancreatic p-cell secretion as well as insulin resistance in patients with type 2 diabetes.
