Objective To investigate the regulatory effect of miR-21 on ADAMTS-1 expression in pulmonary fibrosis model. Methods A mouse model of pulmonary fibrosis was established using bleomycin (BLM) anda model of pulmonary fibrosis was constructed in vitro , the expression level of miR-21 was measured by quantitative real-time polymerase chain reaction (qRT-PCR), while the protein expression of ADAMTS-1 was measured by Western blot. NIH3T3 were transfected with miR-21 mimics and inhibitor in vitro and the cellular expression of ADAMTS-1 was measured by Western blot. Results Compared with the blank group , in mouse models of pulmonary fibrosis , the miR-21 expressions in lung tissues at three time points after BLM-treatment were significantly up-regulated while an evident decrease in ADAMTS-1 expressions were observed (P < 0.01). In vitro pulmonary fibrosis model , NIH3T3 cells after TGF-β1 in concentration 5 μg/L stimulation down-regulated ADAMTS-1 expression and up-regulated miR-21 expression (P < 0.01). NIH3T3 transfected with miR-21 mimics and inhibitor, up-regulated miR-21 expression, while down-regulated ADAMTS-1 protein expression. Conclusions Up-regulation of miR-21 and Down-regulation of ADAMTS-1 might be involved in the progression of pulmonary fibrosis model; miR-21 could negatively regulate ADAMTS-1 expression.

One of the challenges in andrology nowadays is the diagnosis and treatment of external genital abnormalities and defects along with the consequent voiding, sexual, and reproductive dysfunctions, for which no guidelines are yet available. Hitherto, surgical repair and reconstruction are efficient for these diseases. The key to these operations is to individualize surgical strategies according to the specific local lesion and dysfunction, usually involving flap and graft techniques. This article presents our experience in the surgical treatment of penile and scrotal abnormalities and defects with urological and andrological techniques and microsurgical strategies, focusing on the external repair and functional reconstruction. Satisfactory treatment outcomes pivot on a precise evaluation of the disease, a rational design of surgical procedures, and an earnest communication with the patient. Some cases are rather complicated and challenging, usually with complications, and therefore deserve further researches for more effective treatment strategies in clinical practice.

OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.
METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.
RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).
CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.

Objective To construct rat TRESK gene recombinant adenovirus expression vector.Methods TRESK full-length cDNA was cloned from rat dorsal root ganglion cells and confirmed by RT-PCR and sequencing. pAd/CMV/V5-DEST-TRESK was then constructed under the control of CMV-promotor. DH5α colibacillus was translated and the positive recombinants were subsequently identified by PCR and DNA sequencing. 293T cells were cotransfected and packed to produce adenovirus. Results The titer of virus was tested using Hole-by-dilution titer method. The full length of TRESK from rat dorsal root ganglion cells is 781 bp. It was demonstrated that the DNA sequencing was completely consistent with TRESK sequencing of rat recorded in GeneBank. The PCR amplification of the pAd/CMV/V5-DEST-TRESK gDNA was matched with pAD-GFP blank vector as anticipated. The titer of the concentrated virus was 1.31×109 TU/ml. Conclusion Rat TRESK gene recombinant adenovirus vector is constructed successfully.
