The key to clinical paths administration lies in the optimization of the key processes and sectors in medical service, which will achieve an integration that is based on patients and span departments to cover all medical service sectors and processes. The clinical path practice was introduced into the hospital in 2005, and the clinical paths have been put into practice for over 20,000 cases/occasions by the end of 2009, scoring satisfactory social and economic outcomes as of now. For the purposes of speeding up the clinical path practice for expected outcomes in optimizing key medical service processes, we have got the following eight experiences and lessons: (1) Build shared demands; (2)Establish a powerful leadership; (3) Develop and promote visions; (4) Eliminate resistance and pool the forces; (5) Keep on the efforts and focus on details; (6) Reward involvements; (7) Recruit and develop key operators within the hospital; (8) Systemize and supervise the experiences of implementation.Promotion of clinical paths is a renovation in management with its inherent rules. Adoption of appropriate technical strategies and cultural strategies will upgrade the quality and acceptance of clinical path implementation.

Objective:To explore the clinical effect of intravenous immunoglobulin combined with conventional therapy in the treatment of severe pneumonia in infants and children.Methods:Selected the January 2015 to April 2016 in our hospital for treatment of 88 cases of children with severe pneumonia were retrospectively analyzed,which 47 cases by routine treatment plus intravenous immunoglobulin protein (treatment group),41 cases of children only take routine therapy (control group),with a course of 2 weeks.Results:The symptoms of fever,dyspnea,cough,wheezing,pulmonary rales were improved faster in the treatment group than the control group (P＜0.05);after 2 weeks of treatment,IgG levels were significantly higher in the treatment group than the control group(P＜0.05);after 2 weeks of treatment,the serum IL-6 and TNF-α levels were significantly lower in the treatment group than the control group(P＜ 0.05);after 1 week of treatment,57.45％ of patients was cured in the treatment groups while only 34.15％ patients in the control group (P＜0.05).Conclusion:Intravenous immunoglobulin combined with conventional therapy in the treatment of infants with severe pneumonia can significantly improve the theraputic effect and enhance blood immunoglobulin levels.

Objective:To study the change of plasma cyclic nucleotide in patients of rheumatic heart disease with pulmonary hypertension and to evaluate the relationship between plasma cyclic nucleotides and hemodynamics. Methods:Plasma cGMP and cAMP were examined by radioimmunoassay, hemodynamic data were obtained with Swan Ganz catheter and the HP compact configurable monitors. Results:Plasma cyclic nucleotide increased in patients of rheumatic heart disease with pulmonary hypertension and had an obvious correlation with the level of PAPM, PVR, PAWP and CI. Conclusion:Increased cAMP and cGMP is one of the pathophysiological characters of pulmonary hypertension, cAMP and cGMP, as the second messenger, may play an important regulating role in the development of pulmonary hypertension.

Objective To investigate the molecular characteristic,the virulence factors and antimicrobial resistance of Methicillin-resistant Staphylococcus aureus (MRSA) isolated from pediatric patients.Methods Ninety-eight non-duplicate strains of and 49 non-duplicate strains of Methicillinsusceptible Staphylococcus aureus (MSSA) isolated from the three children's hospitals in Shanghai in 2008 were investigated.Panton-valentine leukocidin (PVL) gene was detected by polymerase chain reaction (PCR).The genotypes of staphylococcal cassette chromosome mec (SCCmec) of the MRSA isolates were confirmed by multiplex PCR.The sequence type (ST) of each strain was determined by multilocus sequence typing (MLST),and the algorithm eBURST was used to identify groups of clonal complex (CC).The minimal inhibitory concentrations (MIC) of fourteen antibiotics for all isolates were determined by agar dilution method.Results Among 98 isolates of MRSA,the positive rate of PVL genes was 6.1％ (6/98).In contrast,the positive rate of PVL genes was 4.1％ (2/48) of the MSSA strains.Among 98 isolates of MRSA,4.1％ (4/98),23.5％ (23/98),53.0％ (52/98) and 15.3％ (15/98) of the strains harboured SCCmec types Ⅱ,Ⅲ,Ⅳ and Ⅴ,respectively. The remaining four isolates (4.1 ％) presented a unique SCCmec pattern that could not be classified to any known types by the employed typing assays.Combining the ST and SCCmec type,the predominant clones were ST59-SCCmec Ⅳ (30 strains) and ST239-SCCmec Ⅲ (23 strains),followed by ST5-SCCmecⅣ and ST1-SCCmecⅣ (8 strains for each clone),ST239-SCCmec Ⅴ (6 strains),ST88-SCCmecⅤ (5 strains),ST5 SCCmecⅡ (4 strains),ST59-SCCmec Ⅴ (3 strains),ST8-SCCmecⅣ and ST88-SCCmecⅣ (2 strains for each clone),ST22-SCCmecⅣ,ST910-SCCmecⅣ and S45-SCCmec Ⅴ (1 strain for each clone),eBURST analysis distributed the MRSA isolates into several CC.ST8 and ST239 belonged to ST8 CC,ST1 belonged to ST15 CC,ST910 belonged to ST 30 CC,ST59,ST5,ST88,ST45,ST22,ST9 and ST7 were the origin of their own CC.The results of MIC showed that the 67 strains of MRSA harboring SCCmec type Ⅳ or SCCmec type Ⅴ were more susceptible to various non-β-lactam antibiotics than 27 strains of MRSA harboring SCCmec type Ⅱ or SCCmec type Ⅲ,and no vancomycin-resistant strain was found.Conclusions In three children's hospitals in Shanghai,the PVL gene-positive rate of MRSA isolates is relatively low,SCCmec type Ⅳ and SCCmec type Ⅴ could spread among hospitals to cause a small scale epidemic and have a variety of ST.

BACKGROUND:Nano-hydroxyapatite helps to improve the mechanical properties of bone implants.
OBJECTIVE:To study the clinical effect of nano-hydroxyapatite artificial bone on col apsed fracture of the tibial plateau.
METHODS:Fourteen cases of col apsed fracture of the tibial plateau combined with bone defects from March 2010 to September 2012 were analyzed retrospectively. The bone defect range was from 1.5 cm×1.0 cm to 3.1 cm×4.5 cm. Al patients were treated with nano-hydroxyapatite artificial bone at an implant amount of 5-14 g. Clinical and X-ray observations were applied at 1 week, 1 month and 3 months postoperatively. Hospital for Special Surgery scores were employed for recovery of knee function.
RESULTS AND CONCLUSION:The patients were fol owed up for 12-27 months. Except for one case of a smal amount of wound exudates, no general side effects occurred in 13 cases. X-ray photo showed an integrity interface between nano-hydroxyapatite artificial bone and host bone at 3 months after treatment. Primary healing was obtained in al cases without any complications. Hospital for Special Surgery score was increased to (88.7±4.3) points at 1 year later. These findings indicate that the nano-hydroxyapatite artificial bone has a good biocompatibility and biomechanics, and it may be an ideal artificial bone for repairing col apsed fractures of the tibial plateau.

Objective To investigate the prevalence of nutritional risk and malnutrition,and the application of nutrition support in hospitalized patients with surgically treated gynecologic malignant tumors.Methods 237 hospitalized patients with malignant tumors receiving surgery in Department of Gynecology of Beijing Hospital from January 1 to December 31,2013 were continuously sampled.Nutritional Risk Screening 2002 (NRS 2002) was performed in the morning the day after admission.NRS 2002 score ≥ 3 was considered indicating nutritional risk.Malnutrition was judged in accordance with NRS 2002.The application of postoperative nutrition support was recorded.Results The nutritional risk screening was applicable in all the patients (100％).The prevalence of malnutrition was 5.1％ (12/237) in the whole study population,9.2％ in the elderly (≥65 years),significantly higher than that in the patients ＜ 65 years (2.7％) (P =0.034).The nutritional risk rate was 21.1％ (50/237),which was 29.9％ in the patients ≥ 65 years and significantly lower in the patients ＜ 65 years (16.0％) (P =0.014).The nutritional risk rate in the patients with ovarian and endometrial cancers was higher the rate in those patients with vaginal and vulvar cancer was lower.47 patients (19.8％)received postoperative nutrition support,all being parenteral nutrition,including total parenteral nutrition in 13 patients (5.5％) and single transfusion (providing two or more than two amongs glucose,fat emulsion,andi amino acids) in 34 (14.3％).Tube feeding was not applied in all the patients.33 cases (66％) in the 50 patients with nutritional risk were supported by parenteral nutrition,while 14 cases (7.5％) in the 187 patients without nutritional risk were supported by parenteral nutrition.Conclusions There is nutritional risk in the patients with gynecology malignant tumors,the rate of which is higher in elderly patents (≥ 65 years) than in the patients of other age groups.Therefore,attention must be paid to ensure adequate postoperative nutrition support in the elderly patients.

Methods Forty five cases of CP children were recruited and divided, according to the diagnosis standards, into three groups: diplegia, hemiplegia and tetraplegia groups. Twenty three healthy children served as control. BAEP was recorded from all the subjects and comparisons were done among the various groups. Results The abnormality rate of BAEP in the hemiplegia and tetraplegia groups was significantly higher than that in the diplegia group ( P

Objective To investigate the related factors on effects of uterine artery embolization (UAE) in the treatment of dysmenorrhea in patients with adenomyosis, and to construct and validate the efficacy prediction model. Methods A total of 127 cases of adenomyosis patients with symptoms of dysmenorrhea in Guangzhou No.1 People′s Hospital and Nanfang Hospital of Southern Medical University from June 1999 to December 2009 were reviewed. The evaluation standard was to improve the degree of dysmenorrhea, the related factors of efficacy were analysed. Combined with artificial neural network theory, the effect prediction model was constructed, and the effectiveness of the model was evaluated using receiver operating characteristic (ROC) curve, and the effectiveness of the cut-off point was calculated. The model was validated by 68 cases of patients with adenomyosis in the Nanfang Hospital from January 2010 to November 2014. Results (1) In 127 cases of dysmenorrhea patients, UAE treatment was effective in 98 cases, effective rate was 77.2% (98/127). (2) Age was an independent predictor of effective UAE treatment (HR=1.129, P=0.026);in the range of this study, the greater the age, the higher the UAE treatment efficiency. (3) The developing situation of ovary branches of uterine artery was an independent predictor of effective UAE treatment (HR=0.460, P=0.020), the efficiency of patients whose intraoperative bilateral uterine artery ovarian branch did not develop was 89.7%(35/39), the efficiency of patients whose unilateral uterine artery ovarian branch was developing was 84.1% (37/44) and the efficiency of patients whose bilateral uterine artery ovarian branch were developing was 59.1% (26/44). (4) Blood supply of adenomyosisis was an independent predictor of effective UAE treatment (HR=0.313, P=0.001). Type Ⅰ (bilateral predominated) patients, efficiency was 93.5%(43/46);typeⅡ(bilateral balanced) patients, efficiency was 78.0%(39/50);type Ⅲ (unilateral predominated) patients, efficiency was 51.6% (16/31). (5) UAE for the treatment of adenomyosis efficacy of artificial neural network prediction model was constructed, the model′s area under the ROC curve was 0.808, the optimal cut-off point was 0.669 13. Actual verification of the model, sensitivity was 96.5%, specificity was 81.8%, positive predictive value was 96.5%and negative predictive value was 81.8%, the total accuracy was 94.1%. Conclusions (1) Age, the developing situation of ovary branches and blood supply of adenomyosis are the independent predictors of effective UAE treatment. (2) The artificial neural network prediction model is satisfied with the accuracy and the accuracy of prediction.

ObjectiveTo assess the diagnostic value of preoperative lymphoscintigraphy for lateral lymph node metastasis in low rectal cancer. MethodsFrom May 1999 to March 2001, pelvic and lower abdominal lymphoscintigraphy with 99mTc sulfur colloid was performed on 32 patients with proven colorectal cancer one day prior to operation. Among these patients were 27 rectal cancers, 3 sigmoid cancers and 2 colon cancers. Fifteen cases of rectal cancer with the tumor located at or below the peritoneal reflection received extended lymphadenectomy with lateral dissection (D3 lymphadenectomy). The result of lymphoscintigrams was correlated with histologic lateral node examination. Results The image ratio of pararectal nodes, obturator nodes, and internal iliac aorti lymph trains was 69%, 91%, and 100% respectively. In 15 patients receiving D3 lymphadenectomy, 10 had negative lymphoscintigrams whereas 5 had positive image, and the lateral pathology positive rate was 13%(2/15). Analysis of these results revealed the sensitivity (100%), specificity (77%) and accuracy (80%) of this diagnostic method. ConclusionPelvic and lower abdominal lymphoscintigraphy with 99mTc sulfur colloid could demonstrate the lateral lymph node drainage of low rectal cancer, and the correlation with postoperative histologic lateral node examination was high enough to enable surgeons to adopt an individualized surgical approach.

Objective To investigate the application value of the ultrasonic elastic tissue dispersion quantitative analysis technique in different stages of subacute thyroiditis (SAT).Methods One hundred and forty-four SAT lesions detected from 81 patients were enrolled in the patient group.They were further divided into three subgroups,including acute group (group Ⅰ),medium group (group Ⅱ) and recovery group (group Ⅲ).Another 59 healthy volunteers were collected as control group.All the participants accepted conventional ultrasound and elastographic examinations.Eleven parameters were obtained by the tissue dispersion quantitative analysis software.These parameters were compared between groups and among subgroups by ANOVA.The correlation between all the parameters and the course of SAT were analyzed by Spearman and Multiple linear regression methods.Results Between groups and among subgroups,the complexity (COMP) and correlation (CORR) were not statistically different(all P ＞0.05).Differences of kurtosis (KURT) and angular secon moment (ASM) among the three subgroups were not significant (all P ＞0.05).Differences between groups and among subgroups were significantly different among the value of all the other seven indexes (all P ＜0.01).Moreover,they were all correlated with the clinical staging,with the highest coefficient in area ration of low-strain region (％ AREA)(r =-0.881).Regression model was constructed and only ％ AREA was selected into the regression equation.ROC curves were constructed to estimate the clinic value of ％ AREA in staging patients of SAT,the areas under ROC curves were0.986(group Ⅰ vs group Ⅱ-Ⅲ) and 0.988 (group Ⅰ-Ⅱ vs group Ⅲ[) for ％AREA,respectively.Conclusions The tissue dispersion quantitative analysis technique is helpful in estimating the stiffness of thyroid in patients with SAT.
