ObjectiveTo explore the diagnosis and the surgical operation of concealed penis, and raise the therapeutic efficacy.Methods16 cases of concealed penis were reviewed retrospectively.ResultsAll 16 cases were treated by Devine surgery and got the satisfactory effect, the penis recovered to its good external appearance. All 16 cases had been followed up for four months to two years. The revelation of penis and its external appearance were all satisfied. No complications such as hydrophallus, skin ischemia, haematoma and erection ache occurred.ConclusionThe real concealed penis should be strictly distinguished from buried penis, microphallus and redundant prepuce, and suitable operation pattern can obtain satisfactory effect.

Objective To provide anatomical basis for elevating iliac tissue flap pedicled on the iliolumbar artery.Methods The course,number,outer diameter and distribution of iliolumbar artery were observed on 13 human cadavers.Results All the iliolumbar artery originated from the internal iliac artery.The iliolumbar artery gave off 2 branches (iliacus branch and lumbar branch) when passing between the obturator nerve and the lumbosacral trunk,posteriorly to the psoas major.The mean distance between origin of the iliolumbar artery and bifurcation point to iliacus and lumbar branches was 7.1 (7.1 ± 0.5) cm.The iliacus branch divided into two branches:one artery curved forward and anastomosed with the iliacus branch of deep circumflex iliac artery; the other artery supplied the tissue around the posterior superior iliac spine.The lumbar branch supplied the psoas major and the quadratus lumborum.Conclusion The iliolumbar artery and the iliacus branch is one of the most constant and reliable vessels supplying the iliac bone,and can be used as the pedicle of free or pedicled iliac tissue flaps.

Objective To retrospectivel y analyze the abdominal CT findings and pathological results of the chronic schist osomiasis so as to improve the diagnostic accuracy of the disease. M ethods The plain abdominal CT scanning was performed in 103 cases an d enhanced CT scanning in 81 cases. The pathological specimen which was consist ent with the section of CT scan was obtained in each cases. Results On CT scanning, liver cirrhosis was seen in 84 cases, various calci fication in liver in 71 cases, liver cancer in 12 cases, enlargement of sple en in 78 cases, calcification in spleen in 13 cases, wall-thickening in colon i n 27 cases, calcification in colon in 31 cases, and colon cancer in 9 cases. Pa thological examination revealed various fibrosis and formation of pseudolobule. The eggs and calcification could be seen in pseudolobule and septa, colonic sub mucosa, and regional lymph nodes. Fibrous hyperplasia in colonic wall and hyper plasia in mucous membrane were obvious. Fibrous hyperplasia and calcification w ere seen in spleen, but the eggs were not found. Conclusion The liver and colon are the major organs affected by chronic schistosomias is in abdomen, and the CT findings are obvious too. The pathological features o f spleen are accompanied with liver cirrhosis. CT is the important imaging meth od in diagnosing chronic schistosomiasis and pathological changes.

To improve the effect of teaching practice of blood cell morphology,typical cases of peripheral blood erythrocyte,granulocyte and platelet were chosen,case show and problem-based teaching way were applied to encourage students to find information of autonomous learning.Then teacher organized the class discussion,and the information was analyzed and summarized.In the implementation of the case teaching,we should pay attention to improving students' learning initiative.At the same time,teachers need to have knowledge,comprehensive ability and ability in organization and leadership,to promote students' active participation in discussion in the teaching,pay attention to the information feedback,and improve the teaching details

Objective To investigate an effective method of treating primary hepatic cancer(PHC) with portal venous tumor thrombosis (PVTT). Methods The clinical data Of 23 patients with PHC and PVTT were retrospectivly analysed. Results Of the 23 patieats after hepatoma resection and PVTT extraction, continuous micro dose infusion chemotherapy or perfusion chemotherapy by DDS was adopted. In 8 patients with main portal vein tumor thrombus, 2 died, 4 recured in 6 months. In 8 patients with the first class branch of portal vein tumor thrombus, 2 recurrd in 6 months and 6 recurred in 12 months. In 4 patients with secondary class branch of portal vein tumor thrombus, l recurred in 12 months (P

Aim To establish a model of the vascular endothelial cell (VEC) injury in SDrats.Methods SD rats were randomly divided into the control and the modelgroups. The model rats were injected with adrenaline diluted to 2. 5 times 0. 05 mg?100 g-1 (tid) for 5 d continously. From the 4th d, they were irritated for 5 min in the0℃ cold-water in the middle between adrenaline injections.The control rats weregiven 0. 9% NS as above. At 6th d, blood samples were taken from carotid arteries ofthe rats and the CEC counts, t - PA、PAI activities, 6-keto-PGF1? concentrations andthe platelet aggregation rate(max) were detected respectively. Results In the modelgroup, as compared with those in the control group, t - PA activity and 6-keto-PGF1?concentration decreased significantly(P

Objective To explore the effects of intraventricular administration of insulin on the expressions of Bcl-2,Bax mRNA and neuronal hippocampus apoptosis in rats after cardiopulmonary resuscitation (CPR).Methods This experiment was implemented in the animal Laboratory center of Xuanwu Hospital of Capital Medical University.Thirty male SD rats were randomly (random number)divided into three groups:control group (n=6),CPR group (n=12),insulin treated group ( n =12).CPR was performed at 6 minutes after ventricular fibrillation induced by transesophageal overdrive pacing.Resuscitation procedures lasted until restoration of spontaneous circulation (ROSC).ROSC was defined as the recovery of the supraventricular heart rates and the increase of mean arterial pressure (MAP) ＞ 60mmHg for more than 10 minutes.Ten minutes after ROSC in rats,12.5 μL ( 1 U) regular insulin was injected into the left ventricle in the insulin group,and 12.5 μL isotonic saline was injected the control and CPR groups at least 10 minutes.Real-time PCR was used to observe the expressions of Bcl-2,Bax mRNA in hippocampus CAI after reperfusion 24 h and 72 h.TUNEL staining was used to observe the neuronal apoptosis in all groups after reperfusion 7 days.Blood glucose was monitored in rats before and after CPR.Results ① The Bcl-2mRNA in insulin groups were significantly higher than those in the CPR group after 24 h and 72 h (P ＜0.01 ).The expression of Bcl-2 mRNA in 24 h insulin group were significantly higher than those in 72 h insulin group ( P ＜ 0.01 ) ; There were no significantly different in the Bax mRNA between insulin groups and the CPR and the control group after 24 h and 72 h ( P ＞ 0.05 ) ; ②After CPR 7 d,the apoptotic neurons of hippocampal CA1 area in the CPR group ( 124.75 ± 17.35 ) were significantly higher than those in the control group (5.12 ± 3.26) ( P ＜ 0.01 ) and the insulin group (92.79 ± 7.35 )(P ＜0.01 ); the apoptotic neurons in the insulin group were higher than those in the control group (P ＜0.0l ),and the differences were statistically significant.③There were no significant difference in venous blood glucose in the CPR and insulin groups (P ＞ 0.05).Conclusions Insulin may regulate Bcl-2mRNA expression in hippocampus,inhibit neuronal apoptosis and protect neurons after CPR in rats.

Objective To investigate the buying commercial homosexual sex behaviors among young gay men/bisexual men, and analyze the socio-cultural factors influencing the buying commercial homosexual sex behaviors. Methods A cross-sectional study was performed on risk sexual behaviors for acquired immunodeficiency syndrome (AIDS) with an anonymous questionnaire among 824 young homosexual/bisexual men in Guiyang City, Zunyi City, Anshun City and Tongren City of Guizhou Province in 2016. Respondents were selected by a classified snowball sampling method combined with an interview at AIDS voluntary consultation and testing clinics. Results About 7.8%(95% CI：5.9%-9.6%)of respondents reported the buying commercial homosexual sex behaviors in the last year. The report rate was 13.0% for homosexual men, higher than 5.7% for bisexual men (P＜0.001). The influencing factors of the buying commercial homosexual sex behaviors were average monthly income (OR=6.54, P=0.005), age (OR=3.59, P=0.011), age of liking the same-sex (OR=2.85, P=0.004), marital status (OR=2.62, P=0.005), household registration (OR=2.38, P=0.011), increased risk of oral sex (OR=0.42, P=0.019), possibility of HIV infection (P＜0.005), and the dusckisure of sexual orientation (OR=0.17, P=0.001). Conclusions Young homosexual/bisexual men, especially bisexual men, had a higher report rate of the buying commercial homosexual sex behaviors. The socio-cultural factors influencing the buying commercial homosexual sex behaviors included age of liking the same-sex, increased risk of oral sex, possibility of HIV infection, and the disclosure of sexual orientation.
