Objective To observe the effect of traditional Chinese drug combined with training of musculus quadriceps fexoris on knee osteoarthritis(KOA).Methods70 out-patient clinic KOA patients were divided randomly into the Chinese drug group and control group with 35 cases in each group.The Chinese drug group was treated with Shentongzhuyu medicinal broth PO bid;the control group was treated with Sulindac 0.2 g PO bid.Two groups were combined with the training of musculus quadriceps fexoris,having 10 times per course and 3 courses in total with a 3 days interval between two courses.The therapeutic effect was evaluated with footplate pressure gait analysis and modified JOA marks.ResultsAfter treatment,the effect of the Chinese drug group was superior to the control group(P<0.05),especially 12 weeks post treatment.There maximum weight loading,time integral and weight loading intergral of affected limb of the Chinese drug group significantly improved after treatment(P<0.01),but for the control group,only weight loading intergral improved(P<0.05).ConclusionTraditional Chinese drug combined with training of musculus quadriceps fexoris has better curative effect on the pain and functional disturbance of KOA.

Cognitive estimation is a process in which correct answers can be reasonably estimated by relevant information,instead of be obtained in a direct manner.The cause of cognitive estimation disorder is relevant to executive function and frontal lobe damage.The assessment of cognitive estimation disorder is mainly based on texts such as CET,BCET and TKS,and clinical symptoms are also taken into consideration in this assessment.Future studies include several aspects.Firstly,more efforts should focus on improving diagnostic standard and assessment tools and expanding the related studies.Secondly,it is necessary to focus on the specific brain areas of clinical patients with cognitive estimation disorder,and to strengthen the clinical rehabilitation of cognitive functions.

Objective To evaluate the short-term efficacy of total hip arthroplasty combined with subcutaneous osteotomy in the treatment of CroweⅣ hip dysplasia (DDH).Methods From March 2012 to March 2015,14 patients (16 hips) underwent total hip arthroplasty with femoral distraction osteotomy S-ROM femoral stem prosthesis.And we observed its recent efficacy.Results All patients underwent S-ROM prosthesis.The patients underwent transverse osteotomy of the femoral trochanter.The osteotomy length was 2.0-3.5 cm.The average follow-up time was 19 months.And no complications such as dislocation,vascular nerve injury,deep vein thrombosis and infection were observed during the follow-up.The average Harris scores improved from 42.3 preoperatively to 90.4 postoperatively at 9 months after the operation.The average lengths of preoperative limb shortening and postoperative limb shortening were 6.4 cm and 4.3 cm respectively.The X-ray films showed no dislocation of acetabulum and femoral prosthesis.Bone healing was achieved at 6 months after osteotomy.Conclusion This method could be a good choice for Crowe Ⅳ developmental dysplasia.The short-term efficacy is satisfactory.

Objective:To investigate the influencing factors for early recurrence after curative pancreaticoduodenectomy of pancreatic head cancer.Methods:The retrospective case-control study was conducted. The clinicopathological data of 104 patients with pancreatic head cancer who underwent radical resection in Fudan University Shanghai Cancer Center from May 2014 to May 2015 were collected. There were 62 males and 42 females, aged (61±10)years. Patients underwent carative pancreaticoduodenectomy. Observation indicators: (1) surgical situations; (2) follow-up; (3) influencing factors for early recurrence after curative pancreaticoduodenectomy of pancreatic head cancer. Follow-up was conducted using telephone interview to detect recurrence of patients up to postoperative 1 year. Measurement data with normal distribution were represented as Mean±SD. Count data were described as absolutes numbers, and comparison between groups was analyzed using the chi-square test. Multivariate analysis was analyzed using the Logistic regression model. Results:(1) Surgical situations: 104 patients underwent curative pancreaticoduodenec-tomy successfully. The volume of intraoperative blood loss was (474±280)mL and the number of lymph node dissection was 21±10. (2) Follow-up: 104 patients received postoperative follow-up, 44 of whom had early recurrence. Of the 44 patients with early recurrence, 42 cases had intraperitoneal recurrence including 23 cases with liver metastasis, 7 cases with metastasis in surgical site, 7 cases with retroperitoneal lymph node metastasis, 5 cases with omentum metastasis, 2 cases had extraperitoneal recurrence including 1 case with pleural metastasis and 1 case with pulmonary metastasis. (3) Influencing factors for early recurrence after curative pancreaticoduodenectomy of pancreatic head cancer: results of univariate analysis showed levels of preoperative CA19-9, levels of postoperative CA19-9, the number of lymph node dissection were related factors for early recurrence after curative pancreaticoduodenectomy of pancreatic head cancer ( χ2=5.833, 9.276, 4.261, P<0.05). Results of multivariate analysis showed that postoperative CA19-9 >37 U/mL was an independent risk factor for early recurrence after curative pancreaticoduodenectomy of pancreatic head cancer ( odd ratio=3.599,95% confidence interval as 1.551-8.347, P<0.05). Conclusion:Postoperative CA19-9>37 U/mL is an independent risk factor for early recurrence after curative pancreaticoduodenectomy of pancreatic head cancer.

Aim To explore the differences in hyper-trophic marker genes such as atrial natriuretic peptide ( ANP) , brain natriuretic peptide ( BNP) and β-myo-sin heavy chain (β-MHC) genes in different models of cardiac hypertrophy. Methods Respectively using re-nal abdominal aortic coarctation ( AAC) , arteriovenous fistula ( AVF) and isoproterenol ( ISO) methods to es-tablish C57BL/6 mouse model of cardiac hypertrophy. After modeling, each mouse ’ s body weight ( BW ) , heart weight ( HW) and left ventricular weight ( LVW) were weighed, and the heart weight ( HW/BW) and left ventricular index ( LVW/BW ) were calculated;myocardium by HE staining, pathological morphologi-cal changes were observed; myocardium by immuno-histochemistry, ANP, BNP and β-MHC protein ex-pression was observed;myocardium by Real-time PCR detection, ANP, BNP and β-MHC mRNA expression was observed. Results Compared with control group, HW/BW and LVW/BW were increased in three mod-els. Through the light microscope, each mouse model showed varying degrees of cardiac hypertrophy. ANP, BNP and β-MHC were increased in the protein and mRNA expression. Compared with AAC group, AVF and ISO groups’ myocardial tissue ANP, BNP and β-MHC expression were decreased in the protein and mRNA expression. Conclusions Three cardiac hy-pertrophy models are successful. Cardiac tissue ANP, BNP and β-MHC expression in AAC model exceeds AVF and ISO model.

Objective Although heart transplantation (HTx) has become a standard therapy for end-stage heart diseases,experience with pediatric HTx is limited in China.In this article,we will try to provide the experience with indications,complications,perioperative management,immunosuppressive therapy,and survival for pediatric HTx based on our clinical work.Method This is a retrospective chart review of the pediatric patients undergoing HTx at Department of Cardiovascular Surgery of Union Hospital from September 2008 to December 2015.We summarized the indications,surgical variables,postoperative complications,and survival for these patients.Result Twenty-three pediatric patients presented for HTx at Union Hospital of Tongji Medical College,of whom 12 were male.The age at the time of transplantation ranged from 3 months to 18years (median 14 years).Patient weight ranged from 5.2 kg to 57.0 kg (median 36.0 kg).Pretransplant diagnosis included cardiomyopathy (16 cases),complex congenital heart disease (5cases) and tumors (2 cases).All recipients received ABO compatible donor hearts.Postoperative complications occurred in 14 patients,including cardiac dysfunction,arrhythmia,pulmonary infection,renal dysfunction,and rejection.Two of them experienced cardiac failure and required extracorporeal membrane oxygenation.The immunosuppression regimen was comprised of prednisone,a calcineurin inhibitor,and mycophenolate.All patients recovered with New York Heart Association (NYHA) Class Ⅰ Ⅱ cardiac function and were discharged.Only one patient suffered sudden death 19 months after transplantation.Conclusion Orthotopic HTx is a promising therapeutic option with satisfactory survival for the pediatric population in China with end-stage heart disease.

Objective To investigate the effects of bedside blinding method of active indwelling of nasojejunal tube combined with the nasogastric tube gastrointestinal decompression for patients with severe stroke.Methods 50 patients with severe stroke were selected and divided into two groups by using random number tables,which are the observation group and the control group,with 25 cases in each group.The patients in the observation group were treated with bedside blinding method of active indwelling of nasojejunal tube combined with the nasogastric tube gastrointestinal decompression,while the patients in the control group simply received bedside indwelling of nasogastric tube.The enteral nutritional goal -rate of target feeding volume on the 7th day and the 14th day after admission and trace the incidence of gastric stasis,the reflux and aspiration,the aspiration pneumonia in the patients of the two groups within 14 days and the situation of the days of mechanical ventilation,the days in ICU and the 30 -day mortality of patients were compared in the two groups.Results The enteral nutritional goal -rate of target feeding volume on the 7th day and the 14th day in the observation group were superior to those of the control group[The goal -rate of target feeding volume on the 7th day:88% vs.64%,χ2 =3.947,P =0.047;the goal -rate of target feeding volume on the 14th day:80% vs.52%,χ2 =4.367,P =0.037].Meanwhile the incidence of gastric stasis,the reflux and aspiration,the aspiration pneumonia in the patients of the observation group within 14 days were significantly lower than those in the patients of the control group within 14 days[The gastric retention rate:8% vs.56%(14 /25 ),χ2 =10.784,P =0.001;the reflux rate:0% vs.24%(6 /25),χ2 =4.735,P =0.03;the aspiration rate:8% vs.32%,χ2 =4.500,P =0.034;the incidence of aspiration pneumonia:24% vs.68%,χ2 =9.742,P =0.002].The days of mechanical ventilation and the days in ICU of the patients in the observation group are far less than those of the patients in the control group[The days of mechanical ventilation:(11.16 ±4.86)d vs.(13.72 ±3.67)d,t =-2.101,P =0.041;the days in ICU:(15.36 ±5.66)d vs.(18.72 ±2.99)d,t =-2.625,P =0.012].While there was no significant difference between the two groups on the 30 -day mortality(24% vs.32%,χ2 =0.397,P =0.529).Conclusion The bedside blinding method of active indwelling of nasojejunal tube combined with the nasogastric tube gastrointestinal decompression can significantly improve the enteral nutritional goal -rate of target feeding volume for patients with severe stroke and greatly reduce the incidence of gastric stasis,the reflux and aspiration,the aspiration pneumonia,and limit the days of mechanical ventilation and the days in ICU.Accordingly,it has the value of popularization in the clinical application.

The interaction between Gliotoxin and bovine serum albumin (BSA) was studied by the fluo-rescence, Circular Dichroism (CD) and ultraviolet visible (UV-Vis) techniques. The fluorescent experiment showed that the intrinsic fluorescence of BSA was quenched by the binding of gliotoxin in a static quenching procedure, with an association constant of 7.2?103 L/mol and in hydropobic forces. And the CD spectrum revealed that gliotoxin effected the conformation of BSA by increased the mass of ?-helix.

In China, traditional Chinese medicines （TCMs） have been used in clinical applications for thousands of years. The successful hyphenation of high-performance liquid chromatography （HPLC） and mass spectrometry （MS） has been applied widely in TCMs and biological samples analysis. Undoubtedly, HPLC/MS technique has facilitated the understanding of the treatment mechanism of TCMs. We reviewed more than 350 published papers within the last 5 years on HPLC/MS in the analysis of TCMs. The present review focused on the applications of HPLC/MS in the component analysis, metabolites analysis, and pharmacokinetics of TCMs etc. 50% of the literature is related to the component analysis of TCMs, which show that this field is the most popular type of research. In the metabolites analysis, HPLC coupled with electrospray ionization quadrupole time-of-flight tandem mass spectrometry has been demonstrated to be the powerful tool for the characterization of structural features and fragmentation behavior patterns. This paper presented a brief overview of the applications of HPLC/MS in the analysis of TCMs. HPLC/MS in the fingerprint analysis is reviewed elsewhere.

Objective To examine the relationship between gender and intraventricular hemorrhage (IVH) in very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI).Methods From January 1,1999 to December 31,2012,data on VLBWI and ELBWI,who were admitted to the neonatal intensive care unit of Yuying Children's Hospital within 14 d after birth,were retrospectively collected.The Chi-square test and t test were used to compare neonatal outcomes between male and female infants.The Logistic model was used to analyze the risk factors for IVH.Results A total of 1 008 cases were enrolled,including 615 males and 393 females,895 VLBWI and 113 ELBWI.The incidence of IVH was 15.1％ (152/1 008) and the incidence of severe IVH was 8.4％ (85/1 008).Compared with females,males had a higher total incidence of IVH [17.2％ (106/615) vs 11.7％ (46/393),x2=5.728,P＜0.05] and severe IVH [9.8％ (60/615) vs 6.4％ (25/393),x2=3.896,P＜0.05].These differences were also seen in VLBWI with a birth weight of 1 250 to 1 499 g [IVH:13.7％ (47/344) vs 7.8％ (17/217),x2=4.473,P=0.034; severe IVH:7.6％ (26/344) vs 2.8％ (6/217),x2=5.684,P=0.017].Logistic regression analysis showed that the risk factors for IVH were as follows:gestational age ＜28 weeks (aOR=2.012,95％CI:1.288-3.143,P＜0.05),neonatal respiratory distress syndrome (aOR=l.584,95％CI:1.007-2.492,P＜0.05),invasive mechanical ventilation (aOR=2.743,95％CI:1.826-4.121,P＜0.05),electrolyte disturbance (aOR=2.128,95％CI:1.092-4.149,P＜0.05) and periventricular leukomalacia (aOR=2.901,95％CI:1.312-6.416,P＜0.05),but not male sex (aOR=1.351,95％CI:0.917-1.991,P=0.128).The risk factors for severe IVH were gestational age ＜28 weeks (aOR=2.200,95％CI:1.305-3.708,P＜0.05),invasive mechanical ventilation (aOR=4.714,95％CI:2.809-7.911,P＜0.05) and electrolyte disturbance (aOR=2.232,95％CI:1.047 4.759,P＜0.05),but not male sex (aOR=1.361,95％CI:0.823 2.252,P=0.247).Conclusions Male VLBWI and ELBWI have a higher incidence of IVH and severe IVH,but male sex is not a risk factor for IVH or severe IVH.
