Objective To compare the effect of Devine surgery with different fixed positions in the treatment of concealed penis.Methods According to the different fixed positions,45 patients with concealed penis in our hospital from January 2010 to February 2015 were divided into two groups:20 patients were treated with the method that fixing the scapus penis to dermis of the penis' root (group A);the other 25 patients were treated with the method that fixing the scapus penis to pectineal fascia (group B).The surgical success rate,the penile length,and the edema time after surgery between two groups were compared.Results There was no significant difference in surgical success rate and edema time between two groups (P ＞ 0.05).But the penile length of group B was longer than that of group A after surgery (P ＜ 0.05).Conclusion In the treatment of concealed penis with Devine surgery,comparing to the method which fixing scapus penis to dermis of penis'root,the method which fixing scapus penis to fascia pectinea is much better in penile length and penile appearance.

DNA transposon is a kind of factor that is able to translocate gene in its genome, thus offering an efficient method for permanently modifying the genome of mammals. The piggyBac (PB) transposon system has been proven effective in mammalian genomic engineering, including cancer gene discovery, animal transgenesis, in vivo gene delivery as well as in vitro genetic modification like induced pluripotent stem cells. In addition, piggyBac has many desirable features, such as seamless excision of transposons from the genomic DNA and the potential to target integration events to desired DNA sequences. Therefore, the piggyBac translocation system is an ideal genetic tool in the construction of animal models and gene therapy, and we can anticipate that the piggyBac transposon system will play a more and more important role in biomedical research.

Objective To test the expression of serine/arginine rich splicing factor 1(SRSF1)and apoptosis inhibiting factor(Survivin) in prostate cancer,and study their correlation with the pathological features of prostate cancer,so as to put forward the new targets in the treatment of prostate cancer. Methods SRSF1 and Survivin protein was determined in 20 prostate tissue samples including prostate cancer(n=12)and benign prostat?ic hyperplasia(n=8)by immunohistochemical SP method. SRSF1 and Survivin was correlated to pathological features,and both the relevance was analyzed(no related reports at home and abroad). Results The positive expression rate of SRSF1 protein in prostate cancer tissue cells was 76.37± 5.06%,which was significantly higher than that of benign prostatic hyperplasia(11.30%±1.09%,P<0.05);the positive expression rate of Survivin protein in prostate cancer tissue cells was 86.93%±3.21%,which was significantly higher than that of benign prostatic hyperplasia(17.67%±1.99%, P<0.05);SRSF1 and Survivin protein expressed in prostate cancer organizations and were positively correlated to pathological Gleason grading, and there was significant correlation(P<0.05). Conclusion SRSF1 and Survivin protein were highly expressed in adenocarcinoma tissue,which were significantly increased than that of benign hyperplasia of prostate tissue. The positive expression SRSF1 and Survivin protein were positively cor?related to pathological Gleason grading.The expression of Survivin protein was elevated with the expression of SRSF1 protein in prostate cancer. These preliminary evidence indicated that SRSF1 may up?regulate the expression of Survivin,and thus promote the occurrence and development of prostate cancer.

Objective To summarize our experience in the diagnosis and treatment of malignant peritoneal mesothelioma(MPM). Methods Clinical data of 10 patients admitted with MPM were analyzed retrospectively. Results The main symptoms of MPM were intraabdominal mass and abdominal pain in these patients; Seven patients were of localized type, 3 cases were of diffused type; Preoperatively 7 cases were misdiagnosed as other intraperitoneal tumor, 9 patients underwent laparotomy and tumor resection for a total 16 times, including once in 4 cases, two times in 3 cases, and three times in 2 cases. Seven patients received curative resection in initial operation. Five patients died within one year, 6 cases within two years, Tumors recurred postoperatively in 4 cases. 1 case is still survival 9 years after. Conclusion Being comparatively rare, MPM is often misdiagnosed, the prognosis is very poor, curative resection sometimes provides a long survival for localized type of MPM, when combined with perioperative comprehensive therapy.

Objective To demonstrate the value of eombined application of prenatal ultrasonography with fetal magnetic resonance imaging(MRI) in the diagnosis of monochorionic muhifetal realformations. Methods Fourteen cases of muhifetal malformations,detected by prenatal ultrasonography,received MRI within 48 h afterwards.All diagnosis were confirmed after delivery or mid-term termination.All imaging results of the 14 cases were retrospectively reviewed. Results Among the 14 cases,there were 7 acardias,5 Conjoined twins and 2 demise of multifetuses.Comparing ultrasound with MRI,we found that:(1)In cases with acardia and demise of multifetusea,ultrasound could diagnose correctly and be an important tool for follow-up,while MRI could demonstrate organs and structures of the acardiac recipient more clearly and detect the secondary changes of brain in the donor and survived fetus.(2)In Conjoined twins,ultrasound was superior to MRI in demonstrating the structure and function of cardiovascular system : and equivalent to MRI in identifying stomach,kidney,bladder and limbs;but inferior to MRI in identifying esophagus,lung,liver and intestinal,especially in the brain. And MRI could demonstrate two fetuses and the relationship between them in COnjoined twins simultaneously. Conclusions Prenatal ultrasonography and MRI have their own advantages and disadvantages in diagnosing monochorionic multifetal malformations.But the combination of prenatal ultrasonography and fetal MRI may be more valuable.

Objective To report the clinical results of one stage reconstruction of high-energyinjured limbs. Methods From January 2001 to July 2006,one stage reconstruction was done on 55patients suffered from massive limb trauma,severe open fractures or spoiled limbs caused by high energy.There included 16 patients with Gustilo Type-Ⅲ C fractures,with mangled extremity severity score (MESS)of(6.25 ±2.53)points.All patients were treated with transplantation of free flaps or pedicle skin flaps,fracture fixation,nerve reconstruction or functional reconstruction. Results All limbs were saved and all flaps were transplanted successfully.without protracted course to obtain soft tissue coverage.The hospitalization was mean 24 days(12-63 days)and follow-up ranged from 12 months to 50 months (averaged 23 months).Complications including wound infection,bone nonunion,necrosis and morbidity were significanfly less likely to appear than conventional ways and the ultimate functional results of the saved limbs were at least better than that of artificial ones. Conclusions In comparison with traditional methods,one stage reconstruction of severe high energy-injured limbs has advantages of easier justification of tissue structure,better match of donor and recipient blood vessels,easier operation design,shorter hospitalization and better functional recovery.Definitive wound closure with vascularised tissue transfer can facilitate local blood supply.decrease bone infection and hence promote bone healing.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.

Objective Investigate and intervene the psychological health state of clinical trainees in the hospital of Yuxi City, in order to explore the method to improve the psychological health and clinical quality of teaching. Methods From 2009 to 2013, clinical trainees were investigated by SCL-90. Intervention for interns included holding psychological health lectures and making psychological counseling for the serious interns. At the same time, the teachers were trained to carry out two-way intervention between the teachers and clinic interns and to improve clinical interns' psychological health. Results Before the intervention,among 216 interns,34 (15.74%) showed positive. Except fear factor, other factors were significantly different than national norms ( <0.05). After the intervention, among 149 interns, 20 ( 13.42%) showed positive. Obsessive-compulsive symptom, depression,anxiety,hostility, spirit factors and the mean scores were all lower than before ( <0.05),similar to the national norm.Conclusion Clinical trainees have prominent psychological problems. Teaching hospitals should pay more attention to psychological health of them. Intervention is necessary and effective in improving psychological health and quality of teaching.
