OBJECTIVETo observe the clinical effects of two different circumcision procedures with the Shang Ring and compare their advantages and disadvantages.

METHODSA total of 527 adult males with phimosis or redundant prepuce underwent Shang Ring circumcision by conventional outward replacement (n = 254) and inward placement (n = 273), respectively. We observed the in-ring nocturnal pain, complications, ring-removal pain, degree of edema, recovery time, and patients' satisfaction after surgery, and compared them between the two groups.

RESULTSCompared with the conventional outward placement (5.9%) of the Shang Ring, the inward placement method showed the advantages of mild in-ring nocturnal pain, a low complication rate, significantly reduced ring-removal pain, and mild edema, but exhibited longer healing time.

CONCLUSIONIn Shang Ring circumcision for phimosis and redundant prepuce in adult males, each of the outward and inward placement methods has advantages and disadvantages of its own, but the latter is more advantageous and feasible.

Objective To investigate the immunoregulatory effects of bone marrow-derived mesenehy-real stem ceils (BMSCs) combined with leflunomide (LEF) on mice T-lymphocytes in vitro. Methods BMSCs from BALB/c mice were isolated and expanded. The purity of BMSCs was identified by flow cytometry (FCM). The BALB/c mice's spleen lymphocytes were isolated by using EZ-Sep<'TM> Mouse 1X. Under ConA stimulation, spleen lymphocytes were pretreated with LEF, then washed and co-cuhured with BMSCs. We set up four groups to investigate in this study: group A, spleen lymphocytes alone; group B, spleen lymphocytes with BM- SCs; group C, LEF-pretreated spleen lymphocytes alone and the group D, LEF-pretreated spleen lymphocytes with BMSCs. T-lymphocytes proliferation was assessed by MTT. FCM was used to analysis T-lymphocytes apoptosis and surface markers of CD69 and CD28. The mRNA expression of interleukin (IL)-2, IL-10 were detected by real-time RT-PCR. Results In vitro, the T-lymphocytes'values of A570 nm were significantly lower in group B and group C, compared with group A (group B vs group C vs group A, 0.578±0.042 vs 0.502± 0.040 vs 0.778±0.035, P<0.01), while the value of A<,570 nm>in group D was 0.218±0.033, which was also obviously lower than that in group B and group C (P<0.01). There were no suppressing effects on T-lympho-cytes'activation and expression of IL-2 had been observed. The proportion of apoptotic T-lymphocytes in group B and group D were (2.29±0.32)％ and (4.22±0.98)％, which was significandy lower than that in group A (8.08±1.20) (P<0.01). The expression of IL-10 in group B and C were also lower than that in group A (group B vs group C vs group A, 0.098±0.039 vs 0.054±0.022 vs 1.000, P<0.01 ). Either, the expression of IL-10 in group D was 0.023±0.015, which was obviously lower than that in group B and group C (P<0.01). Conclusion BMSCs combined with LEF show synergistic immunoregulatary effects on mice's T-lymphoeytes.

Objective To study haemostatic percutaneous injection therapy for the management of vascular damage in patients with renal injuries guided by contrast-enhanced ultrasonography(CEUS).Methods Which of 56 patients with renal trauma were diagnosis by CEUS,37 cases with grades Ⅱ-Ⅳ renal injuries were brought into our study.According to wound degree and accompanying active bleeding,they were divided into experiment group (percutaneous injection hemostatic treatment)and control group(conservative treatment).Results Thirty-seven renal trauma manifest low perfusion in lesions by CEUS,and the contrast agent could be seen overflow to renal pelvi and the location of capsule in 13 patients.The patients were divided into experiment group(17 cases)and control group(20 cases).The color of hematuria of 9 patients in experiment group became gradually light at 30 mins after treatment.and the color of 7 cases become normal,and hematuria of the only one was iterative appear.The color of hematuria of 9 patients in control group became gradually light in 24-72 hours,others' hematuria became gradually light in 5-14 days.The time of color of hematuria become light of the former was shorter than those of the latter(P<0.05).Reexamination by ultrasound and renal function and urine routine at 1,3 and 6 months after treatment,the results of all patients indicated normal.Conclusions Haemostatic percutaneous injection therapy for renal trauma guided by contrast-enhanced ultrasonography has very obvious hemostatic efficacy.Its advantages included may be used for effective,minimally invasive control of renal injuries(grades Ⅱ-Ⅳ),and can be a feasible management of active bleeding at bedside.

Objective To study feasibility of combined haemostatic percutaneous injection therapy guided by contrast-enhanced ultrasonography (CEUS) in treatment of renal injuries. Methods Eighteen New Zealand rabbits were inflicted with kidney injury imitating grades Ⅲ-Ⅳ blunt injuries. The animals were randomly and equally divided into three groups, Group A ( treated with hemocoagulase),Group B ( treated with hemocoagulase and Alpha-cyanoacrylate) and Group C ( control group, given normal saline). The hemostatic time, hemostatic effect, and perirenal hematoma were observed. Results A perirenal hematoma was observed one hour after treatment. The perirenal fluid thickness was (0.200 ±0.012) cm in Group A, (0.050 ±0.002) cm in Group B and (0.400 ±0.009) cm in Group C, with statistical significance between two test groups and Group C (P ＜ 0.05 ). At days 7 and 14 following treatment, lesion length and cross section was ( 1. 107 ±0. 143) cm and (0.433 ±0. 163) cm in Group A, (0.567 ±0.082) cm and (0. 160 ±0. 078) cm in Group B, and (0.980 ±0. 203) cm and (0.686 ± 0. 157) cm in Group C. There was statistical significance between the test groups (Groups A and B) and Group C (P＜0. 01) at day 14. The lesion size in Group A was lager than that in Group B (P ＜ 0.01 ). One month after treatment, a slight nephrohydrosis occurred in Group B. Conclusions Either injection of simple hemocoagulase or combined use of hemocoagulase and Alpha-cyanoacrylate guided by CEUS can attain positive hemostatic effect, but the latter one is more rapid and reliable.

The combination of Danggui and Honghua (GH) is a popular herb pair commonly used in clinic for the treatment of blood stasis syndrome in China. To evaluate the activating blood circulation and dissipating blood stasis effects of the combination of different proportions of Danggui and Honghua on acute blood stasis rats, and optimize the proportion of GH to have the best activating blood circulation and dissipating blood stasis effect. Acute blood stasis rat model was induced by subcutaneous injection of adrenaline and ice water bath. The blood stasis rats were administrated intragastrically with GH (1 : 0, 4 : 1, 2 : 1, 3 : 2, 1 : 1, 2 : 3, 1: 2, 1 : 4 and 0 : 1) extracts. The whole blood viscosity (WBV), plasma viscosity (PV), and high shear whole blood relative index (HSWBRI), low shear whole blood relative index (LSWBRI), and erythrocyte aggregation index (EAI) were tested to observe the effects of GH on hemorheology of blood stasis rats. And the maximum aggregation induced by adenosine diphosphate (ADP) was tested to observe the effect of GH on platelet aggregation index of blood stasis rats. In addition, the prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT) and plasma fibrinogen (FIB) were tested to observe the effects of GH on blood coagulation function of blood stasis rats. Then principal component analysis and multi-attribute comprehensive index methods were both used to comprehensively evaluate the total activating blood circulation and dissipating blood stasis effects of GH. The results showed that the hemorheological indexes and coagulation parameters of model group both had significant differences with normal group. Compared with model group, GH (1 : 0, 4 : 1, 2: 1, 3 : 2, 1 : 1, 2 : 3, 1 : 2, 1 : 4 and 0 : 1) could improve all the blood hemorheology indexes and regulate part indexes of blood coagulation function and platelet aggregation in acute blood stasis rats. Based on principal component analysis and multi-attribute comprehensive index methods, GH 1 : 1 and GH 3 : 2 both had the best effect of blood circulation and dissipating blood stasis, and the effect of GH 1 : 1 was slightly better than GH 3 : 2. These results suggest that GH could obviously ameliorate the abnormality of hemorheology and blood coagulation function in acute blood stasis rats. The optimized proportion of GH was consistent with regulations of medicine usage that GH 1 : 1 had the highest frequency used in traditional Chinese formulae. It could provide scientific basis for more effective application of the compatibility between Danggui and Honghua in modern clinic medicine.
