MicroRNAs(miRNAs)are a series of short non-coding RNAs that can regulate the expressions of protein-coding genes posttranscriptionally.They modulate gene expression by targeting mRNA for degradation or blocking translation via base-pairing to complementary sites in the 3'-untranslated region of the target mRNAs.Their functions are related to many biology progresses and diseases including tumor and hematopoietic differentiation.They are speculated to be critical in the development, progression and prognosis of leukemia. In this review, we will summarize the research progress on miRNAs in leukemia.

Objective To assess the efficacy of the mixtures of different concentrations of ropivacaine(R) and chloroprocaine(C)for epidural anesthesia in patients undergoing hysterectomy.Methods Sixty ASAⅠorⅡpatients aged 27-56 weighing 45-75 kg undergoing elective hysterectomy were randomly divided into 4 groups(n= 15 each);groupⅠ0.75% R alone;groupⅡ0.5% R-1% C;groupⅢ0.5% R-1.5% C and groupⅣ0.75% R+1% C.The epidural catheter was placed at L_(2,3)interspace and advanced 3.5 cm into the epidural space in cephalad direction.A total of 22 ml of epidural solution was injected in each group.The onset time,block height and duration of sensory block and the onset time,degree and duration of motor block(using Bromage scale)were assessed.The use of supplementary drugs(ketamine and ephedrine)and side effects were recorded.Results The onset time of sensory and motor block was significantly shorter in groupⅡ,ⅢandⅣthan in groupⅠ(0.75% R alone).The duration of sensory and motor block was significantly shorter in groupⅡandⅢthan in groupⅠandⅣ.The incidence of hypotension was significantly increased but the incidence of discomfort produced by traction on the viscera during operation was reduced in groupⅣas compared with groupⅠ.Conclusion The anesthetic efficacy of epidural 0.5% ropivacaine is significantly enhanced when mixed with 1.0% or 1.5% chloroprocaine.

AlM: To study the trabeculectomy clinical effect of use tunnel knife to make double - deck scleral flap and to cut off the layer scleral flap of glaucoma.METHODS: Using the random grouping method to divide 46 cases (60 eyes) of glaucoma into the treatment group of 24 cases (32 eyes) and control group of 22 cases (28 eyes). The treatment group, tunnel knife was used to make double- deck sclera flap and superficial scleral flap about the size of 5mm×5. 5mm, 1/3 scleral thickness, under the sclera flap made another one about the size of 3. 5mm× 4mm, 1/3 scleral thickness, resected the middle layer of the sclera flap, removed 2mm×2mm trabecular tissue, underwent routine peripheral iridectomy, could adjust suture the superficial scleral flap, sutured Ball fascia and bulbar conjunctiva. ln control group, routine glaucoma trabeculectomy was undergone.RESULTS:Patients were followed up for 1a, the vision in treatment group was obviously better than that in the control group, with a statistically significant difference (P< 0. 05). The postoperative intraocular pressure of the two groups of patients were significantly lower than that of the preoperative one. Postoperative 1 and 3mo, no statistical significant difference of intraocular pressure in two group(P>0. 05). But after 6 and 12mo, the intraocular pressure of the treatment group were significantly lower than that of the control group, with statistically significant difference (P<0. 05). Postopeartive 1a, the cumulative complete success rate and conditions for successful rate were 90. 63% and 96. 88% in the treatment group, and those were 75% and 89. 29% in control group. There was significant difference between two groups(P<0. 05).CONCLUSlON:The trabeculectomy have a good effect to lower the intraocular pressure by use tunnel knife to make double-deck scleral flap and to cut off the layer scleral flap. The scleral flap have uniform thickness, smooth surface, and the function of the filtering bleb maintained for a long time, less postoperative complications, suitable for various types of glaucoma, so it is worthy of clinical promotion.

Objective To evaluate the preoperative diagnosis and treatment of primary non-specific ureteritis,and to better understand this disease.Methods Three cases of primary non-specific ureteritis (1 man and 2 women)were reported.Their age was 28,38,68 years,respectively.One ease was found to have hydronephrosis on B-ultrasound at physical examination with no symptoms,and 2 had abdominal pain. The lesions were detected in lower part of the ureter in 2 cases,and in middle in I.The patients were diag- nosed preoperatively with combined use of MRU and ureteroscopy.Partial resection of the diseased part of the ureter was performed in all the cases.Results Pathological findings confirmed the diagnosis of non-spe- cific ureteritis.Microscopy showed necrotic tissue and inflammatory cell infiltration of ureteral mucosa,dilated and congested blood vessels,hypertrophic muscular layer,and proliferation of fibrous tissue.During the fol- low-up of 2 years,the patients had no symptoms and were free from hydronephrosis.Conclusions The eti- ology of primary non-specific ureteritis is unclear,and no typical symptoms can be found clinically.Combined use of MRU and ureteroscopy is helpful for definite diagnosis of the disease.Partial resection of the diseased part of the ureter has good results.

Objective To explore the clinical feature of acquired pure amegakdryocytic thrombocytopenic purpura(AATP).Methods 18 patients were analyzed retrospectively.And 112 patients with ITP in the same term were to be control group.Each group's megakaryocytic (MK),platelet (PLT) count,mean platelet volume (MPV) and platelet associated immunoglobulin G(PAIgG) were rested.Results The MK total number of AATP group was obvious decreased or even absent,while the ITP group was increased[(0.8?1.5) vs (195.0?47.3),P0.05).About the PAIgG posi- tive rate,AATP group was 55.6 % while ITP group was 83% (P

Objective To investigate the diagnosis and operation treatment of primary intrahepatic cholangiocelhlar carcinoma (PICC), for improving the level of diagnosis and treament of PICC. Methods The clinical data of 18 cases with PICC confirmed by operation were analyzed retrospectively. Results In the early stage, no specific symptoms was found in all the 18 cases, the positive cases of AFP, CEA, CA199 and live cirrhosis were 2, 4, 3 and 4. The diagnostic rates of ultrasound examination, CT and MRI were 11.1%(2/18), 42.9%(6/14) and 45.5% (5/11 ). Seven cases were diagnosed as suffering from PICC and the others were misdiagnosed. Of all the 18 patients, 8 cases underwent radical resection and 10 cases received palliative excision. Conclusions PICC patients lack clinical features and serum tumor marker,the rato of misdiagnosis is high, but that of radical resection is low. Knowing its clinicopathological features well. Radicalresection is the best way for treatment of PICC.
