Objective To evaluate the efficacy of recombinant human interferon α-2b gel onflooding prevention in loop electrosurgical excision procedure (LEEP) during and after the operation.Method The 152 patients with cervical disease were randomly divided into three groups: group A(recombinant human interferon α-2b gel treatment group), group B (hypophysin treatment group)and groupC(control group). Results The amount of intraoperative bleeding and the amount of post-operative bleedingof the group A was (2.57±1.19) ml and (2.24±1.75) ml, the group B was (3.00±1.49) ml and (45.86±26.14) hal, the group C was (45.62±39.57) ml and (56.90±41.90) ml, respectively. There was no differencebetween group A and group B in the amount of intraoperative bleeding (P>0.05), but significantly less thangroup C (P<0.01). There was no difference between group B and group C in the amount of post-operativebleeding (P>0.05), but significantly much more than group A (P<0.01). Conclusion Recombinanthuman interferon α-2b gel is effective on reducing intraoperative and post-operative bleeding in LEEP.

MicroRNAs(miRNAs) are endogenous non-coding RNAs,about 20 nucleotides in length.They play a pivotal role in the regulation of genes involved in diverse biology processes such as cell development,proliferation,differentiation and apoptosis by the translation repression or mRNA degradation.Recent evidence has suggested that miRNA alterations are involved in the initiation and progression of various human cancer including hepatocellular carcinoma(HCC),and miRNA-expression profiling of HCC has identified signatures associated with diagnosis,staging,progression and prognosis.As a novel molecular target,miRNAs holds great promise in diagnosis and biotherapy of HCC.

Circulating nucleic acids (CNAs) are extracellular nucleic acids found in cell-free serum,plasma and other body fluids from healthy subjects as well as in patients. The ability to detect and quantitate specific DNA and RNA sequences has opened up the possibility of diagnosis and monitoring of diseases,especially in the field of cancer. Furthermore,in some recent studies it has been suggested a kind of non-coding RNA-microRNA (miRNA),also exist in cell-free serum and plasma,highlighting the field of using CNAs to diagnose cancer. As a novel tumor marker,tumor-specific circulating miRNAs holds great promise in early diagnosis of cancer.

Background Corneal chemical burns,especially hazards of alkali burn become increasingly prominent.Clinically,anti-inflammatory,immuno-suppression,corneal transplantation are the common treating method for corneal alkali burn.But the research of tissue repair under the microenvironment of corneal alkali burn is necessary.Objective The aim of this study was to investigate the therapeutic effect of deproteinised calf serum eye gel on the corneal alkali burn.Methods Alkali burn model of cornea was established on the right eyes by putting the filter paper with 0.5 mol/L NaOH on the center cornea for 1 minute in 24 white rabbits.The model rabbits were divided randomly into 4 groups.Normal saline solution,deproteinised calf serum eye gel,blank matrix gel or recombinant bovine basic fibroblast growth factor(rb-bFGF)eye-gel was topically administered 4 times per day for 14days in the 4 groups,respectively.The inflammatory reaction was examined under the slit lamp and scored based on Ando' s criteria.Corneal fluorescine staining was performed to calculate the corneal ulcer area and scored based on Trousdale' s criteria.Histopathological examination of corneas was performed on the fourtcenth day after experiment.The use of the experiment animals complied with ARVO Statement.Results Corneal edema and opacification were seen in the model eyes with the modeling successful rate 100％.On the seventh day after experiment,the severe ulcer of cornea and hypopyon appeared in the normal saline solution group.Corneal epithelium was intact but the intrarocular structure was invisible in the blank matrix gel group.In th(c) rb-bFCF group,corneal new vessels were seen,however,the corneal ulcer completely regrow in the deproteinised calf serum eye gel group.In 3,5,7,10 and 14days after examination,the corneal inflammatory scores were significantly lower in the deproteinised calf serum eye gel group and rb-bFGF group than those of the normal saline solution(P＜0.01).No significant difference was found in the inflammatory score between the deproteinised calf serum eye gel group and rb-bFGF group (P＞0.05) but was significantly lower than the blank gel matrix group (P ＜ 0.05).With respect to the corneal ulcer,the score was decreased in the deproteinised calf serum eye gel group compared with the normal saline solution group and blank gel matrix group (P ＜ 0.05).Howcver,no significant difference was found in the corneal ulcer score between the deproteinised calf serum eye gel group and rb-bFGF group in various time points (P＞ 0.05).Conclusions Deproteinised calf serum eye gel can promote the healing of corneal ulcer and remit the inflammatory response afler corneal alkali burns with a better effectiveness than rb-bFGF.

Objective To explore the association of tumor necrosis factor(TNF)-α gene-308G/A single nucleotide polymorphism with susceptibility to syphilis.Methods The study includes 56 patients with early symptomatic syphilis,38 with eady latent syphilis,and 102 normal human controls.The-308G/A single nucleotide polymorphism of TNF-α gene was detected in all subjects by real-time fluorescent quantitative PCR.Results The frequency of TNF-α-308 G and A allele was 0.926 and 0.074 in patients with early syphilis,0.941 and 0.059 in the controls,0.929 and 0.071 in patients with early symptomatic syphihs,0.921 and 0.079 in patients with early latent syphilis.No significant difference was found between patients with early syphilis and the controls or between patients with early symptomatic syphilis and those with early latent syphilis in the frequency of either allele (MG) at-308 position of TNF-α gene(all P>0.05).Conclusion There seems to be no evidence for association between TNF-α gene-308G/A single nucleotide polymorphism and susceptibility to syphilis.

Objective To improve the corrected results of the nasal deformities of the hare lip nose. Methods Based on the reposition of the lower lateral cartilages and the caudal septum, the authors corrected the secondary hare lip nose with the L shaped silicon rubber graft to reinforce and model the nasal tip.Results From 1996～2000, the procedure was performed for 20 cases (15 male, 5 female ), aged from 16～21 years. Follow up was from 3 months to 4 years. All cases obtained satisfactory results. Conclusions The results of utilizing L shaped silicon rubber graft combined with reposition of the mislocated nasal cartilages are better than the latter method only, especialy for the nasal tip. The procedure is easy to learn .The material silicon rubber graft is cheap and can be trimmed very conveniently. And it can also correct the saddle nose at the same time.

Objective To observe the effect of sitagliptin combined with insulin aspart 30 in the treatment of secondary failure of sulphonylurea in type 2 diabetes mellitus. Methods Fifty-six cases were divided into group A and group B in random block design, with 28 cases of each group. The patients in group A was treated with sitagliptin combined with insulin aspart 30, while the patients in group B was given subcutaneous injection of insulin aspart 30R. All patients were treated for 12 weeks. Fasting plasma glucose(FPG), 2-hour postprandial plasma glucose(2 hPG), glycosylated hemeglobin(HbA1c), insulin secretion index (HOMA-β), body mass index (BMI), and incidence of low blood glucose before and after treatment were compared. Results Compared with that in group B, FPG [(5.61 ± 1.14) mmol/L vs. (7.8 ± 1.22) mmol/L], 2 hPG [(7.62 ± 1.35) mmol/L vs(9.72 ± 1.41) mmol/L] and HbA1c [(7.11 ± 0.83)%vs.(8.32 ± 1.04)%] in group A had a significant decrease;HOMA-β[(50.31 ± 5.12) vs. (41.86 ± 4.53)] of group A was higher than that of group B (P
