Seventy eight patients who need bedside temporary cardiac pacing through left subclavian vein were divided into 2 groups. In group A (n=40) the "three-point measurement" method was applied: a was set for puncture point of left subclavian vein, b was the middle point of angulus sterni, c was the right edge of the sternum at the 4th intercostal space, the length of ab + bc was used to estimate the depth of right atrium for electrode to reach until the success of right ventricular pacing. In group B (n=38) the puncture to the right or the left subclavian vein for temporary pacing was performed with X-ray guidance in catheter lab. Total rescuing time, procedure time and the threshold voltage of cardiac pacing was recorded in each groups. All cases were successful paced without complication related emergency cardiac pacing with a successful rate of 100% in both groups. There was not difference between two groups in the procedure time and the threshold voltage of cardiac pacing (P > 0. 05). The total rescuing time of A group was (10.0± 2.2) min, and that of B group was (30.5±3.5) min (P<0.01). The average depth of the electrode was ab + bc +9.0 cm. The results suggest that "three-point measurement" method is valuable in the guiding of bedside emergent cardiac pacing through the left subclavian vein.

BACKGROUNDSurgical treatment of insertional Achilles tendinopathy should be considered when a variety of conservative measures fail. To achieve a satisfactory outcome, thorough debridement of the Achilles tendon is critical, besides excision of the bursitis and the calcaneal exostosis. Central tendon-splitting provides straightforward access to the calcified or degenerative tissue within the Achilles tendon. For Achilles tendon reconstruction if detachment is present, several surgical techniques have been reported. Controversy surrounds the technique can provide maximum security for reattachment of the Achilles tendon. The SutureBridge double-row construct, initially used in rotator cuff repair, is probably a good choice.
METHODSTen consecutive patients with insertional Achilles tendinopathy underwent tendon reattachment using the SutureBridge technique through a central tendon-splitting approach. We retrospectively evaluated the surgical outcomes, which included pre- and postoperative visual analog scale (VAS), postoperative Maryland Foot Score (MFS), postoperative range of motion of the affected ankle, and related complications. Follow-up was performed in the outpatient department.
RESULTSOne patient was lost to follow-up. Nine patients (two male and seven female; 12 feet) were reviewed with a minimum follow-up of six months (range 6-30 months). The postoperative VAS pain scores were markedly lower than the preoperative scores. Postoperative MFS was 92.1±8.0 (range 74-100). No intra- or postoperative complications were found, except for one case of delayed healing incision. At last follow-up, all affected ankles achieved their normal range of motion, and patients were able to resume daily activities without any assistive device.
CONCLUSIONSAlthough a randomized control trial with a larger sample may be necessary to compare the central tendon-splitting combined with the SutureBridge technique with other techniques, our results confirmed that it was a promising alternative for treatment of insertional Achilles tendinopathy.

OBJECTIVETo present a new mini-invasive surgery for compressive optic neuropathy (CON) in Graves' ophthalmopathy (GO) by adequately decompressing the orbital apex and correcting proptosis, and to analyze its results.
METHODSA retrospective chart was reviewed in 29 patients receiving orbital decompression for the treatment of CON secondary to GO from October 2006 to May 2011. All patients diagnosed CON were in stable and inactive phase of GO at least for 6 months. All patients received endoscopic transethmoid medial orbital wall decompression to reduce the compression on the orbital apex. In the meanwhile, an endoscopic transethmoid intraconal fat-removal orbital decompression was performed to remove parts of intraconal fat with a special aspiration/cutting instrument to further reduce the proptosis. All patients were followed up periodically.
RESULTSof improvement of visual acuity (VA), color vision, and amount of proptosis reduction and incidence of induced diplopia 9 months after surgery was recorded for analysis its feasibility.
RESULTSForty-five orbits of 29 patients were included in the study. At the 9 months review, 44 of 45 eyes (97.8%) improved their VA from -0.65±0.30 (x±s) preoperatively to -0.24±0.22, with a mean improvement of 0.55±0.17 (t=-13.012, P<0.001), 23 of 29 eyes (79.3%) had improved color vision (P<0.001), and the mean reduction in proptosis was (7.07±1.59) mm (range 4-11 mm). Postoperative symmetry to within 2 mm were achieved in all patients. Except 1 patient complaining of deterioration in diplopia following surgery, no patients presented new on-set diplopia postoperatively.
CONCLUSIONThe endoscopic transethmoid medial orbital wall decompression combined with the endoscopic transethmoid intraconal fat-removal orbital decompression is an effective treatment with minimal morbidity for both visional recovery and improvement of proptosis for CON in GO.

OBJECTIVETo analyse retrospectively the diagnosis and treatment of severe pneumonia in kidney transplantation recipients.
METHODSBetween January 1999 and December 2003, 172 adult patients underwent kidney transplantation at our department. In all severe pneumonia cases, empirical therapy was initiated with aztreonam, erythromycin and ganciclovir. And the therapy was switched to proper antibiotics according to the results of sensitivity testing. Responsible pathogen was detected by study of BAL (bronco-alveolar-lavage), sputum and blood specimen. Analyses included cell differential count, cytopathologic examination and cultures for bacteria, fungi and viruses. The immunosuppressive therapy was drastically reduced. Hypoxia was relieved by BiPAP (Bi-level Positive Airway Pressure) or mechanical ventilation if necessary.
RESULTSSeventeen cases (9.9%) of pneumonia were observed in the 172 recipients, only 11 (65%) patients experienced severe pneumonia, 1 (9%) of them died. Fever was the most common symptom on presentation (82%). On presentation 46% of the patients presented with classical clinical syndrome of fever accompanied by cough and dyspnea. Positive rate of BAL and blood culture were 100% and 46% respectively. BiPAP and mechanical ventilation were required in 6 and 2 cases respectively.
CONCLUSIONBAL is preferred for early detection of responsible pathogen. A combination of drastic reduction of the immunosuppressive regimen, implementation of appropriate empirical antibiotics, proper BiPAP or mechanical ventilation are important.

BACKGROUNDMuch research has been focused on ischemia/reperfusion injury (IRI) to the transplanted organs. As a free radical, nitric oxide (NO) plays an important role in IRI. In this study, the production of NO and its functions during IRI were monitored in rat models after allotransplantation of kidney grafts.
METHODSOf 75 male LEW rats, 30 served as donors, and the remaining 45 rats were divided into three groups (15 rats in each group): controls (group 1), kidney allotransplantation followed by bilateral nephrectomy during reperfusion (group 2), 2 hours before operation, donors and recipients were treated with N(G)-nitro L-arginine methyl ester (L-NAME), a NO synthase inhibitor, at a dose of 30 mg/kg (group 3). Bilateral nephrectomies were performed while kidney grafts were reperfused. The kidney grafts were hypothemically stored for 24 hours. The production of NO before and after reperfusion was measured by electron paramagnetic resonance (EPR). The creatinine level, the glomerular filtration rate (GFR) and the protein carbonyl content in tissue samples were recorded on the first and the fifth day after operation. The data were evaluated by one-way analysis of variance. Differences were considered to be statistically significant when a P value was less than 0.05.
RESULTSAfter reperfusion for 15 minutes, the production of NO increased remarkably and kept increasing till 120 minutes, after which the level returned to normal. In group 3, which was pretreated with L-NAME, creatinine levels were higher than those in group 2 at the 24th hour (4.10 +/- 0.50 mg/dl vs. 3.77 +/- 0.42 mg/dl, P < 0.05) and the 120th hour (3.19 +/- 0.79 mg/dl vs. 2.22 +/- 0.53 mg/dl, P < 0.05). GFR levels in group 3 were lower than those in group 2 at the 24th hour (0.50 +/- 0.12 ml/min vs. 0.71 +/- 0.19 ml/min, P < 0.05) and the 120th hour (0.59 +/- 0.38 ml/min vs. 1.27 +/- 0.23 ml/min, P < 0.01). The content of protein carbonyl in tissue samples of group 3 was lower than that in group 2 at the 24th hour (29.01 +/- 7.02 nmol/mg protein vs. 49.39 +/- 13.13 nmol/mg protein, P < 0.05), but was higher than that at the 120th hour (75.71 +/- 16.74 nmol/mg protein vs. 57.93 +/- 15.32 nmol/mg protein, P < 0.05).
CONCLUSIONSAfter transplantation of hypothemically stored kidney grafts, the increased NO production in the early stage has protective effects on the transplanted kidney. Application of L-NAME to inhibit NO production is harmful to the recovery of the renal functions of kidney grafts.

OBJECTIVETo explore the preventive and treatment effects of smectite powder on enteral bacterial translocation in scalded rats.
METHODSFifty-four Sprague-Dawley (SD) rats were randomly divided into three groups, i.e. normal control (A, n = 6), burn control (B, n = 24), and burn treatment (T, n = 24) groups. The rats in B and T groups were fed with tracing bacteria JM109, which was transfected with PUC19 plasmid in advance. The rats were subjected to 30% TBSA scald injury after the plasmid was shown to have colonized in the intestine. Smectite powder (0.6 g/day/kg) was fed to rats of T group immediately after the scalding, while those in B group received no smectite powder. Bacterial translocation in blood and mesenteric lymph nodes in all groups was observed and identified by enzyme digestion at 12 post scald hour (PSH) and on 1, 3 and 5 post-scald days (PSD). The contents of malondialdehyde (MDA) and superoxide dismutase (SOD) were determined in rat intestinal tissue. And the degree of injury to the entire small intestine was observed pathologically. The villus height of intestinal mucosa was measured, and the rate of epithelial nuclear splitting of mucosal crypts was calculated.
RESULTSThe number of rats with positive blood bacterial culture in B group was obviously higher than that in A and T groups (P < 0.05) on 1 and 5 PSD. The bacterial quantity in mesenteric lymph nodes (MLN) in T group on 1 PSD (38 +/- 16 CFU/g) and 5 PSD (68 +/- 20 CFU/g) were obviously lower than those in B group (228 +/- 67 vs 183 +/- 29 CFU/g, P < 0.05). There was significant difference in the intestinal contents of MDA and SOD between B and T groups at each time point (P < 0.05). The rat jejunum villus height and the epithelial nuclear splitting in the small intestine mucosa in T group were evidently higher than those in B group (P < 0.05 or 0.01).
CONCLUSIONSmectite powder is beneficial to the protection of the intestinal mucosa in scalded rats, and can effectively prevent postburn intestinal bacterial translocation in rats.
