Objecive To evaluate and compare the efficacy of injecting tissue glue and lauromacrogol in modified sandwich method combined with synchronous ligation for patients with esophageal and gastric variceal.Methods 42 cases of patients with esophageal and gastric variceal were randomly divided into synchronous treatment group (22 cases) and sequential treatment group (20 cases). Both group received modiifed sandwich method for gastric varices (lauromacrogol-tissue adhesive-lauromacrogol). Synchronous treatment group meanwhile received synchronization ligation for esophageal varices, but sequential treatment group received sequential ligation after one week. The hemostasis rate, effective rate of varices, rebleeding and complications rate were analyzed.Results There were no signiifcant difference in hemostasis rate, effective rate and rebleeding rate between two groups. The incidence of complications, such as chest and abdominal pain, fever, transient bacteremia were equal between these two groups. No patients had ectopic embolism. The number of ligation device in synchronous treatment group was more than sequential treatment group (8.19 ± 2.01 vs 7.81 ± 1.78,P > 0.05), and the rate of esophageal varices disappearance was inferior to sequential treatment group (59.09% vs 70.00%), however, there were no statistical difference (P > 0.05).Conclusion Endoscopic injection of tissue glue and lauromacrogol synchronization ligation is safe and effective for esophageal and gastric variceal with low complication rates. This method could reduce gastroscopy times and medical expenses, and is worthy of further investigating.

AIM: To study effects of hyperbaric oxygen (HBO) and cyclosporin A (CsA) on the contents of active oxygens and nitric oxide (NO) in spleens of skin transplanted mice. METHODS: The donor mice BALB/C and receptor mice Cs7BL/6 were tested for skin transplantation. The HBO group mice were,treated with 99.2 % oxygen under 0.25 MPa for 1.5 hours, while CsA group mice were treated with CsA 0.5 rmg· kg- t· d- 1 by abdomen injection. After 14 days, the spleen were extracted the contents of malondialdehyde (MDA) and NO and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH - PX), catalase (CAT) and NO synthases (NOS) were determined. RESULTS: (1) Compared with the control group, the transplantation group, HBO group and CsA group have markedly increased the content of MDA and the activities of GSH - PX and CAT; Compared with the transplantation group, the CsA group have markedly increased activity of SOD and reduced activities of GSH - PX and CAT; the HBO group have markedly reduced the activity of GSH - PX and increased the activities of CAT and SOD (P < 0.01 ). (2) Compared with the control group, the transplantation group have markedly increased the content of NO and the activity of NOS; Compared with the transplantation group, the HBO group have markedly increased the activity of NOS and reduced the content of NO ( P < 0.01 ); The content of NO and the activity of NOS in CsA group was not changed significantly. CONCLUSION: In the lymphocytes of the transplantation group, the peroxidation is intensified, and the content of NO and the activity of NOS increased. HBO and CsA may activate the systems of oxidation/antioxidation and NO/NOS in spleen, which may be related to their mechanism of inhibition rejection.

Whether M3 cholinergic receptor signal transduction pathway is involved in regulation of the activation of NF-kappaB and the expression of chemokine MOB-1, MCP-lgenes in pancreatic acinar cells was investigated. Rat pancreatic acinar cells were isolated, cultured and treated with carbachol, atropine and PDTC in vitro. The MOB-1 and MCP-1 mRNA expression was detected by using RT-PCR. The activation of NF-kappaB was monitored by using electrophoretic mobility shift assay. The results showed that as compared with control group, M3 cholinergic receptor agonist (10(-3) mol/L, 10(-4) mol/L carbachol) could induce a concentration-dependent and time-dependent increase in the expression of MOB-1, MCP-1 mRNA in pancreatic acinar cells. After treatment with 10(-3) mol/L carbachol for 2 h, the expression of MOB-1, MCP-1 mRNA was strongest. The activity of NF-kappaB in pancreatic acinar cells was significantly increased (P<0.01) after treated with M3 cholinergic receptor agonist (10(-3) mol/L carbachol) in vitro for 30 min. Either M3 cholinergic receptor antagonist (10(-5) mol/L atropine) or NF-kappaB inhibitor (10(-2) mol/L PDTC) could obviously inhibit the activation of NF-kappaB and the chemokine MOB-1, MCP-1 mRNA expression induced by carbachol (P<0.05). This inhibitory effect was significantly increased by atropine plus PDTC (P<0.01). The results of these studies indicated that M3 cholinergic receptor signal transduction pathway was likely involved in regulation of the expression of chemokine MOB-1 and MCP-lgenes in pancreatic acinar cells in vitro through the activation of NF-kappaB.

Objective To investigate the expression of caspase-10 in differentiated thyroid carcinoma and association with its development and metastasis. Methods Thyroid samples from 37 patients in a period from January 2006 to December 2007, with differentiated thyroid carcinoma were retrospectively analyzed for caspase-10 by immunohistocbemistry(streptavidin-perosidase, S-P), compared to control group of 46 cases with nodtdar goiter. The relationship between the expression of caspase-10 and the clinical pathologic characteristics of thyroid carcinoma were also explored simultaneously. Results caspase-10 were observed as brown or yellow particles located in the cytoplasm or cell membrane of nodular goiter but there were no significant evidence for its positive expression in thyroid carcinoma, caspase-10 expression was markedly down-regulated in differentiated thyroid carcinoma(29.73%,11/37) compared with benign nodules(71.74%,33/46, χ2=14.528, P<0.01). The positive expression in 18 cases with lymph node metastasis(11.11%,2/18) was significantly lower than those in 19 patients without lymph node metastasis(47.37%,9/19; χ2=4.210, P<0.01). There was no significant correlation(P> 0.05) between the expression of caspase-10 and the clinical pathologic characteristics including male, age, TNM stage and pathologic type. Conclusion Down-regulation of caspase-10 may play a critical role in carcinogenesis and development of differentiated thyroid carcinoma.

OBJECTIVETo analyze effects of fracture of processus styloideus ulnae on prognosis in the treatment of distal radial fracture of type C according to AO classification.
METHODSThis was a retrospective case-control study, and the information was got ten through case evaluation and follow-up, including sex, age, patient satisfaction, Gartland & Werley score and radiographic score. There were 76 patient treated with open reduction and plate fixation in People's Hospital Affiliated to Peking University from July 2006 to July 2011. All the patients were divided into two groups: no combination with fracture of processus styloideus ulnae (group A, 56 cases), combination with fracture of processus styloideus ulnae (group B, 20 cases). The patients in group A and B were treated with open reduction and internal fixation; however the fracture of processus styloideus ulnae was not fixed. The indexes such as clinical data, bone grafting, joint movement, Gartland & Werley score and radiographic score were compared between two groups.
RESULTSThe ulnaris pain of patients in group B was more obvious than that in group A. The local VAS, palmar and dorsal flexion degree of wrist joint, motion VAS, patients satisfaction score, radial and ulnar deviation degree, pronation and supination of forearm degree, Gartland & Werley score and radiographic score were separately 0.1 ± 0.1, (51.1 ± 1.9)°, (60.2 ± 1.9)°, 0.6 ± 0.1 (23.1 ± 0.9)°, (28.7 ± 1.3)° (81.5 ± 2.6)°, (68.2 ± 2.7)° 1.9 ± 0.3, 89.6 ± 12.3 in group A; and separately 0.3 ± 0.3, (51.4 ± 2.3)°, (66.6 ± 1.7)°, 0.5 ± 0.2, (24.5 ± 2.0)°, (26.9 ± 1.8)°, (80.3 ± 2.5)°, (70.3 ± 3.7)°, 1.2 ± 0.4, 92.5 ± 7.5 in group B; there were no statistical differences in above indexes between two groups.
CONCLUSIONWhether the distal radial fracture with a concomitant unrepaired ulnar styloid fracture or not exerts no influence on mainly outcomes including function, radiography and motion of the wrist.

Objective To investigate the effect and safety of endoscopic injection of tissue adhesive in a modified method combined with ligation for esophageal and gastric varices. Methods 60 patients with esophageal and gastric varices were randomly distributed to the treatment group (group A),who was treated with the modi-fied sandwich method(lauromacrogol -tissue adhesive-lauromacrogol)and combined with ligation for esophageal varices. The treatment group were compared with that 60 controls(group B),who was treated with the traditional sandwich method (lipiodol - tissue adhesive - lipiodol) and combined with ligation for esophageal varices. The hemostatic rate ,rebleeding rate ,improvement rate of gastric varices ,the rates of esophageal varices disappear-ance and complications were compared. Results The hemostasis rate were 98.32% and 96.41% between the two groups (P > 0.05). The improvement rate of gastric va rices (94.83% vs. 82.50%,P < 0.05) and the rate of esophageal varices disappearance(86.67% vs. 76.67%,P < 0.05)in the group A were both higher than those in the group B(49.57% vs. 41.23% ,P < 0.05). The amount of tissue adhesive in the group A was lower than that in the group B(2.47 ± 0.79 mL vs. 3.02 ± 0.68 mL ,P<0.05). The incidence of rebleeding rate ,fever ,transient bacteremia were equal between the two groups(P > 0.05),but the rate of chest and abodminal pain in the group A was higher than those in the group B (70.00% vs. 53.33%,P < 0.05). 1 patient in the group B had ectopic pulmonary embolism ,but improved after treatment. Conclusions Endoscopic injection of tissue adhesive in a modified method combined with ligation is effective and safe for esophageal and gastric varices ,and is worthy fur-ther investigation.

Objective To explore link of change of plasma C-reactive protein (CRP) and atrial fibrillation (AF). Method The hsCRP enzyme-linked immunosorbent assay (ELISA) methods were used to measure plasma CRP levels in 21 patients with lone paroxysmal AF (LPAF) during AF and 7 days after return to sinus rhythm ;28 patients with lone sustained atrial fibrillation(LSAF) and 27 patients with rheumatic heart disease and chronic AF(RHD).Levels of plasma CRP were compared to levels in 32 patients with paroxysmal supraventricular tachycardia(PSVT) and 20 voluntary healthy subjects. Results Patients with LPAF,LPAF and RHD had high levels of CRP when compared with PSVT and the healthy subjects.No significant changes of CRP levels were found between the onset AF patients and those after 7 days of recovery.Patients with lone persistent AF and rheumatic heart disease with persistent AF had higher levels of CRP than those with LPAF,but have no significance.There were positive correlation between the duration of AF and the levels of CRP.But there were no relation with left atrial size on echocardiography,sex and ages. Conclusion These results indicate that elevated CRP levels in AF patients may play an important role in the occurrence and sustainment of AF.

OBJECTIVETo compare the effects and complications of subinguinal microscopic ligation, laparoscopic transperitoneal varicocelectomy, laparoscopic retroperitoneal varicocelectomy, open retroperitoneal high ligation, and interventional embolotherapy in the treatment of varicocele.
METHODSWe conducted a retrospective study that included 632 varicocele patients treated by subinguinal microscopic ligation (group A, n = 79), laparoscopic transperitoneal varicocelectomy (group B, n = 120), laparoscopic retroperitoneal varicocelectomy (group C, n =137), open retroperitoneal high ligation (group D, n = 283), and interventional embolotherapy (group E, n = 13). We compared the baseline and 3-month postoperative semen parameters, postoperative complications, and pregnancy rate among the five groups of patients.
RESULTSThe operation time was longer in groups A ([2.02 ± 1.25] h) and E ([2.17 ± 1.02] h) than in the other three groups, while the postoperative hospital stay was the shortest in group E ([1.1 ± 0.1] d). Intestinal injury or incision bleeding occurred intraoperatively in 2 cases in group B and 1 case in group E. Postoperative scrotal edema developed in 3.7, 17, 10, and 19% of the patients in groups A, B, C, and D, respectively, but not in group E. The rate of 1-year recurrence was the lowest in group A (1.6%) and highest in group E (22%). Sperm concentration and the percentages of progressively motile sperm and morphologically normal sperm were improved postoperatively in all the patients (P < 0. 05), but there were no statistically significant differences among the five groups either in the above three parameters or in the postoperative pregnancy rate (P > 0. 05).
CONCLUSIONIn the surgical treatment of varicocele, laparoscopic retroperitoneal approach involves short operation time and few complications, subinguinal microscopic ligation has the advantages of little injury, rapid recovery, and few complications but requires specialized microsurgical techniques, and interventional embolotherapy leaves no incision scar and needs only local anesthesia and 1-day postoperative hospital stay, which is uitable for those with a contraindication to anesthesia.
