Objective To discuss the less invasive stabilization system(LISS)in treatment of fractures around the knee joint.Methods Between February 2002 and December 2005,103 cases of periarticular fractures of knee joint were treated with LISS in our department.There were 58 cases of comminuted distal femoral fracture and 45 cases of comminuted proximal tibia fracture.Follow-ups were conducted once per week during the first four weeks and once per month in the following months to observe whether such complications as loosening of internal fixators and nail breakage would occur.Results All the cases were followed up for a mean time of 16.5 months(range, 6 to 27 months).Loosening and breakage of internal fixation was found in only one case,while others obtained bony union.In fractures of types A and C,the knee range of motion varied from 95?to 145?(average,130?)and 85?to 140?(average,110?)in flexion respectively.HSS score:excellent in 84 cases(81.6%),good in 15 cases (14.6%),fair in three cases(2.9%),and poor in one case(0.9%).Conclusions The LISS can be the best choice for the treatment of periarticular fractures around the knee joint,but we should take care to implant the plate and screws in a proper position and direction and avoid early weight-bearing.In application of the 13-hole plate, large incision should be made to approach the distal tibia for fear of damaging the superficial peroneal nerve.

We have constructed an immunotoxin(Ng76-TCS),which was composed of a monoclonalantibody directed against human melanoma and trichosanthin(TCS)——a single chain ribosomeinactivating protein.The cultured human melanoma cells(M21)were inhibited effectively byNg 76-TCS.The cytotoxicity of Ng76-TCS to M21 cells was 2,000-fold higher than that of free TCS and Ng76 mixture.A conjugate,which was prepared with normal mice immunoglobulinand TCS(NIgG-TCS),was 160-fold less cytotoxic to M21 cells.Meanwhile Ng76-TCS was125-fold less cytotoxic to nontarget cells Hela.These results showed that the immunotoxinNg76-TCS was a potent and specific anti-human melanoma agent.

RBRVS assessment system has been carried out in hospital performance management,which meets the needs of the reform of public hospitals and hospital fine management.The one year practice at the hospital has built a new model of performance management based on the RBRVS assessment system.Calculation of the RVS point values and CF values of the operations and determination of such indexes as the indirect workload reference coefficient of the grades,will yield the amount of the performance bonus of individual departments and posts.The new model proved effective in improving staff incentives and efficiency,saving human resource cost and controllable materials.However,its design and implementation is a complex systematic engineering in need of measures suited to local conditions and steady progress.
4.Analysis of Clinical Effectiveness of Tafluprost by Ocular Pulse Amplitude.
Journal of the Korean Ophthalmological Society 2013;54(2):303-309
PURPOSE: To analyze the clinical effectiveness of tafluprost used in the treatment of glaucoma, using ocular pulse amplitude (OPA) measurements with dynamic contour tonometry (DCT). METHODS: Sixty patients (119 eyes) with normal tension glaucoma (NTG) or primary open angle glaucoma (POAG) treated with tafluprost or other eyedrops were investigated in the present study. Intraocular pressure (IOP) was measured with Goldmann applanation tonometry (GAT), and OPA was measured with DCT, before and after treatment, retrospectively. RESULTS: In 20 patients treated with tafluprost, IOP decreased from 17.1 mm Hg before treatment to 13.0 mm Hg 3 months after treatment (24.0% descent rate), and OPA decreased from 2.35 to 1.57 (33.2% descent rate). For 20 patients who switched from another monotherapy to tafluprost, IOP decreased from 15.7 mm Hg to 13.2 mm Hg from 15.7 mm Hg (15.3%) and OPA from 2.38 to 1.69 (27.7%). CONCLUSIONS: Tafluprost used to treat glaucoma has a large OPA and IOP lowering effect and, therefore can be applied to patients who have a large OPA with glaucoma progression in spite of well controlled IOP.

OBJECTIVETo explore the intervention of baicalin on signal transduction and activating transcription factor expression of ulcerative colitis (UC) patients.
METHODSRecruited were UC patients at Outpatient Department of Digestive Disease, Inpatient Department of Digestive Disease, Center for Digestive Endoscopy of College City Branch, Guangdong Provincial Hospital of Traditional Chinese Medicine, and Southern Hospital affiliated to Southern Medical University from June 2010 to January 2011. They were assigned to the UC group (33 cases) and the diarrhea-predominant irritable bowel syndrome (IBS-D) group (30 cases). Another 30 healthy subjects were recruited as a healthy control group. Peripheral blood mononuclear cells (PBMCs) in vitro intervened by different concentrations baicalin were taken from UC patients. IL23R gene expressions in vitro intervened by different concentrations baicalin were detected using Q-PCR. Expressions of signal transducer and activator of transcription 4 (STAT4) , STAT6, phosphorylated-STAT4 (p-STAT4), and p-STAT6 were detected using Western blot. Serum levels of IFN-γ, IL-4, IL-6, and IL-10 were measured by ELISA. Effects of different concentrations baicalin on expressions of PBMCs, and levels of IFN-γ, IL-4, IL-10 of UC patients were also detected.
RESULTSCompared with the negative control group, 40 µmol baicalin obviously decreased IL23R gene expression of UC patients (P <0. 01). Compared with the healthy control group and the IBS-D group, p-STAT4/STAT4 ratios increased, p-STAT6/STAT6 ratios decreased, levels of IFN-γ, IL-4, IL-10 all increased in the US group (all P <0. 05). Compared with the negative control, 5 and 10 µmol baicalin groups, 20 and 40 moL baicalin obviously decreased p-STAT4/STAT4 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously increased p-STAT6/STAT6 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously lowered levels of IFN-γ and IL-4, and elevated IL-10 levels (all P <0. 05).
CONCLUSION40 µmoL baicalin could in vitro inhibit p-STAT4/STAT4 ratios, adjust p-STAT6/STAT6 ratios and related cytokines, thereby balancing the immunity and relieving inflammatory reactions of UC.

Objective To examine the kinetics of plasma S100A12 and soluble receptor for advanced glycation end products (sRAGE) in infants and young children undergoing cardiopulmonary bypass ( CPB),and to investigate whether they could protective the occurrence of noninfectious pulmonary complication (NPC) after cardiac surgery.Methods This was a case-control study.The subjects included all children aged <3 years old who underwent cardiac surgery with CPB during the period from June 1st to July 31st 2011.The patient who showed pulmonary inflammation or had abnormal liver or renal function before surgery was excluded.The remain patients were divided into 2 groups according to whether they had developed NPC postoperatively.Twenty patients were grouped into NPC because they developed the complications of pleural effusion,chylothorax,partial lung collapse,pulmonary hypertensive crisis,airway disorders,pneumothorax,pneumomediastinum,or phrenic nerve palsy.Forty patients were categorized into the no-NPC group.Plasma concentrations of S100A12 and sRAGE were measured using ELISA at baseline,before CPB,immediately after CPB,1 h,12 h and 24 h after operation.Differences concentrations between two groups were analyzed with t test.A stepwise logistic regression analysis was used to indentify the independent risk factor for NPC.A P value <0.05 was considered statistically significant.Results Plasma levels of S100A12 and sRAGE dramatically increased immediately after CPB ( P < 0.01 ).The levels of sRAGE dropped to lower than baseline level (P <0.05),while S100A12 was still at high level 24h after operation (P <0.01 ).Levels of S100A12 and sRAGE immediately after CPB in NPC group were significantly higher than the no-NPC group (P < 0.05).Twenty-four hours after operation,levels of S100A12 were still higher in NPC group than no-NPC (P < 0.01 ),while levels of sRAGE were similar in the two groups ( P > 0.05 ).In the stepwise logistic regression analysis,plasma S100A12 level immediately after CPB remained as a independently predictor for postoperative NPC (OR =1.042,95% CI:1.010 ~ 1.076,P =0.011 ).Levels of S100A12 immediately after CPB were positively associated with mechanical ventilation time ( r =0.47,P < 0.01 ),duration of surgical Intensive Care Unit ( r =0.407,P =0.002) and hospital stay ( r =0.421,P =0.01 ).Conclusions Plasma levels of S100A12 and sRAGE were significantly increased immediately after CPB and the elevated plasma S100A12 immediately after CPB served as an early reliable biomarker of the occurrence and the prognosis of NPC after CPB in infants and young children.

PURPOSE: Bridge anticoagulation therapy is mostly utilized in patients with mechanical heart valves (MHV) receiving warfarin therapy during invasive dental procedures because of the risk of excessive bleeding related to highly vascular supporting dental structures. Bridge therapy using low molecular weight heparin may be an attractive option for invasive dental procedures; however, its safety and cost-effectiveness compared with unfractionated heparin (UFH) is uncertain. MATERIALS AND METHODS: This study investigated the safety and cost-effectiveness of enoxaparin in comparison to UFH for bridge therapy in 165 consecutive patients (57+/-11 years, 35% men) with MHV who underwent invasive dental procedures. RESULTS: This study included 75 patients treated with UFH-based bridge therapy (45%) and 90 patients treated with enoxaparin-based bridge therapy (55%). The bleeding risk of dental procedures and the incidence of clinical adverse outcomes were not significantly different between the UFH group and the enoxaparin group. However, total medical costs were significantly lower in the enoxaparin group than in the UFH group (p<0.001). After multivariate adjustment, old age (> or =65 years) was significantly associated with an increased risk of total bleeding independent of bridging methods (odds ratio, 2.51; 95% confidence interval, 1.15-5.48; p=0.022). Enoxaparin-based bridge therapy (beta=-0.694, p<0.001) and major bleeding (beta=0.296, p=0.045) were significantly associated with the medical costs within 30 days after dental procedures. CONCLUSION: Considering the benefit of enoxaparin in cost-effectiveness, enoxaparin may be more efficient than UFH for bridge therapy in patients with MHV who required invasive dental procedures.

PURPOSE: To report the results of switching treatment to vascular endothelial growth factor (VEGF) Trap-Eye (aflibercept) in neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) refractory to anti-VEGF (ranibizumab and bevacizumab). METHODS: This is a retrospective study involving 32 eyes from 29 patients; 18 were cases of neovascular AMD and 14 were cases of PCV. The best-corrected visual acuity (BCVA) and central macular thickness (CMT) of spectral-domain optical coherence tomography were evaluated. RESULTS: BCVA and CMT improved from 0.58 to 0.55 (p = 0.005) and from 404 to 321 microm (p < 0.001), respectively, after switching to aflibercept. The 14 eyes that received 6 or more aflibercept injections remained stable at 0.81 to 0.81 and 321 to 327 microm (p = 1.0, 0.29), respectively, after 3 aflibercept injections. The 10 eyes that received 3 or more bevacizumab injections after 3 or more aflibercept injections worsened, from 0.44 to 0.47 and from 332 to 346 microm (p = 0.06, 0.05), respectively. The results showed similar improvement of BCVA and CMT in neovascular AMD and PCV. CONCLUSIONS: Aflibercept seems to be effective for improvement and maintenance of BCVA and CMT for neovascular AMD and PCV refractory to anti-VEGF. Switching from aflibercept back to bevacizumab treatment may not be a proper strategy.
