OBJECTIVETo investigate clinical efficacy and feasibility of double-plating fixation via anteriormiddle approach in treating type C3 distal femoral fractures.

METHODSFrom August 2008 to August 2011, 12 cases with type C3 distal femoral fractures were treated, including 5 open fractures and 7 closed fractures. Among them, there were 8 males, 4 females with an average of 40 years (ranged, 25 to 55 years). There were 7 in left side, 5 in right side. Nine cases were caused by car accident, 3 cases by falling down. The duration from injury to hospital was form 20 minutes to 5 days (mean 135 min). After tibia bone traction for 5 to 8 days, the operation were performed by double-plating fixation via anteriormiddle approach, and autograft of iliac bone or allograft bone grafting were given to bone defect. Knee joint function was evaluated according to Merchanetal criteria.

RESULTSThe operation time was from 110 to 160 min, with an average of 135 min, the blood loss was from 300 ml to 500 ml,with an average of 400 ml. Post-operative wound were stage I healing. All patients were followed up from 16 to 36 months (mean 24 months). No infection, reduction loss, nonunion, deep vein thrombosis occurred. Bone healing time was for 18 to 24 weeks with an average of 21 weeks. According to the Merchanetal criteria, 4 cases got excellent results, 6 good, 1 fair and 1 poor.

CONCLUSIONDouble-plating fixation via anteriormiddle approach for type C3 distal femoral fractures is an effective way, which has advantages of obvious exposure, simple manipulation, anatomical reduction, stable fixation. However,operation indications and operating instructions should be strictly followed.

Objective To explore the difficulty and strategy of percutaneous transheptic stenting for the junction of malignant hepatic duct obstruction. Method Twenty-three patients with highly malignant biliary obstruction received percutaneous transheptic biliary drainage (PTBD) by placement of stent and/or internal-external drainage tube. All the 23 patientws were followed up to determine the successful rate of surgery, the incidence of complications, decreased serum level of bilirubin, patency time of biliary stent and survival time. Results The initial operation was sucessful in 22 cases, accounting for 95.65%. Twenty-one patients had significant decline in total bilirubin (60%) and 2 had not (10%). The levels of alanine aminotransferase (GPT) and aspartate aminotransferase (GOT) decreased markedly and returned to nomral in an average of 18 d. After operation, 2 patients had fever,1 biliary tract bleeding, 6 pain in the right upper abodminal region, 1 localized peritonitis around the puncture point, 3 GPT increase and 1 drainage tube slip. There were no serious complications such as hemorrhea and biliary fistula etc. The symptoms of all these complications disappeared in 2 to 5 days through haemostasis, anti-inflammatory therapy and liver function protection. The median survival time was 8.5 months. Conclusion Although the merging of malignant hepatic duct obstruction stenting is difficult, try to pass through the obstruction by guide wire and master the right methods of operation can significantly improve the successful rate of surgery.

Objective To evaluate the effect of evidence- based nursing for patients receiving percutaneous coronary intervention and stent implantation. Methods A total of 136 patients with coronary heart disease were randomly divided into the intervention group (n = 68) and the control group (n = 68). Traditional nursing measures were employed for the patients of the control group , while evidence-based nursing intervention was adopted for the patients of the intervention group. The patient’s comfortableness, satisfaction and the occurrence of complications were determined at 24, 48 and 72 hours after the operation, and the results were compared between the two groups. Results At 24, 48 and 72 h after percutaneous coronary intervention, the each dimension score of GCQ and the total score of the intervention group were significantly higher than those of the control group (P<0.05). The occurrence of back pain, urinary retention and hypotension in the intervention group was significantly lower than those of the control group (P < 0.05). Patient’s satisfaction extent of the intervention group was significantly better than that of the control group (P < 0.05). Conclusion Evidence-based nursing intervention can effectively enhance the nursing skill and orientation, and reduce the occurrence of back pain, urinary retention and hypotension, thus improve patient’s comfortableness and satisfaction. Therefore, evidence - based nursing intervention should be recommended in clinical practice.

Objective To study the effect of interventional treatment of iliac and femoral vein stenosis concomitant with deep venous thrombosis. Method Fifty-three patients were divided into 5 groups. In group A after placing into inferior vena cava a filter,11 patients adopted Amplatz Trombectomy Device for thrombolysis or ORSIS thrombolysis and persistent thrombolysis through popliteal vein. In group B thrombus was taken out through guiding catheter and then persistent thrombolysis through popliteal vein after placing into inferior vena cava filters in 9 cases. In group C 13 patients adopted persistent thrombolysis through femoral arteries. In group D 8 patients received persistent thrombolysis through popliteal vein. In group E persistent thrombolysis through foot veins was carried out in 12 patients. Seventeen patients received implanted stents and balloon-expansion in iliac and femoral veins. Results Symptoms disappeared in 26 patients(49.0%), significantly improved in 21 patients (39.6%), improved in 3 patients (5.7%), did not improve in 3 patients (5.7%), respectively. The repatency of iliac and femoral vein was achieved in more than 80% of the 17 patients. Complications developed in 3 cases in the course of thrombolysis. Conclusion The effect of mechanical removal of thrombus, persistent thrombolysis through catheter and transluminal angioplasty is safe and satisfactory.

OBJECTIVETo explore the clinical effects of cervical posterior pedicle screw internal fixation and interbody fusion for the treatment of atlanto-axial vertebral instability fractures.

METHODSFrom July 2008 to July 2013, 21 patients with atlanto-axial vertebral instability fractures were treated with vertebral pedicle screw internal fixation and interbody fusion through posterior approach. There were 14 males and 7 females, aged from 20 to 55 years old with an average of 32 years. Lifted and guided the atlanto-axial vertebral pedicle screw to reduce atlanto-axial vertebral displacement.

RESULTSAll patients were followed up from 6 to 24 months with an average of 12.5 months. Wounds got healed without complication of infection. Clinical symptoms were relieved at 6 months after operation. According to ASIA score standard to assess at 6 months after operation, the items of motion, light touch and needle score had obviously improved, and respectively were 99.45 ±0.27, 111.09 ± 0.47,111.11 ± 0.58. VAS and NDI scores also had obviously improved, and respectively were 1.04 ± 0.38 and 12.56 ± 2.24.

Objective To investigate the effect of long intergenic non-coding RNA COX2 (lincRNA-COX2) on apoptosis and polarization of Listeria monocytogenes (Lm)-infected RAW264.7 cells. Methods RAW264.7 cells were cultured and divided into control group (uninfected cells), Lm infection group, negative control of small interfering RNA (si-NC) group, si-NC and Lm infection group, small interfering RNA of lincRNA-COX2 (si-lincRNA-COX2) group, si-lincRNA-COX2 and Lm infection group. RAW264.7 cells were infected with MOI=10 Lm for 6 hours, and then the inhibition efficiency of siRNA transfection was detected by fluorescence microscope and quantitative real-time PCR (qRT-PCR). The expression levels of cleaved-caspase-3(c-caspase-3), caspase-3, B-cell lymphoma-2 (Bcl2), Bcl2 associated X protein (BAX), arginase 1 (Arg1), inducible nitric oxide synthase (iNOS) were detected by Western blot analysis. Results c-caspase-3/caspase-3, BAX/Bcl2 and iNOS were significantly up-regulated, while the level of Arg1 was down-regulated in Lm-infected RAW264.7 cells compared with control group. LincRNA-COX2 knockdown inhibited the increase of protein levels for BAX/Bcl2, c-caspase-3/caspase-3 and iNOS in Lm-infected RAW264.7 cells, while the level of Arg1 in Lm-infected RAW264.7 cells was up-regulated. Conclusion Knockdown of lincRNA-COX2 can inhibit cell apoptosis and suppress the macrophage polarization into M1 type in Lm-infected RAW264.7 cells.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.
