Objective To explore the relative factors affecting the functional restoration of knee joint after the fracture of patella, and to anticipate the effect of middle term and short time rehabilitation therapy. Method 23 patients with limited flexion function of knee joint after the fracture of patella, accepted the routine rehabilitation treatment in out  patient service, and some of the patients adopted local heat therapy at the same time. The 13 factors have been selected for regression analysis step by step under the help of SPSS statistical software. Result The flexible degree of the knee joint before rehabilitation (X1), the non smooth posterior edge of patella (X2), and the immobilization time of the joint (X3) are relative factors for the flexible degree of knee joint 1 month after ehabilitation (Y1) and the flexible degree of knee joint 3 onths after rehabilitation (Y2), and Y1 can also be affected by whether surgery therapy or not (X4), (partial regression coefficient P< 0.05). The differences between theoretical mean and practical mean of Y1 and Y2 are 5.6％ and 4.2％ respectively in the 23 cases. Conclusion The flexible degree of the knee joint before rehabilitation, whether the posterior edge of patella is smooth or not, and the immobilization time of the joint are relative factors affecting the middle term and short term flexible function of knee joint after the fracture of patella, and short term restoration can also be affected by whether surgery therapy or not. The effects of middle term and short term rehabilitation can be predicted by regression equation primarily.

Objective To explore the effect of emergency pre-hospital care intervention procedures on patients with acute cerebral hemorrhage treatment. Methods One hundred and eighty patients with acute cerebral hemorrhage rescued in the ambulance of our hospital from June 2011 to June 2014 were selected as the observation group , and another 120 patients of acute cerebral hemorrhage escorted by family members to our hospital during the same period were set as a control group. The patients in the observation group were given guidance nursing, on-site emergency care, emergency care and hospital transit emergency care, and the patients in the control group were given rescue in the hospital. The two groups were compared in terms of effective transit time. Results The effective transit time for the patients in the observation group was (0.87 ± 0.19)h, significantly shorter than the control group (1.26 ± 0.35) h (P<0.05). The complication rate in the observation group was 22.22%, significantly lower than that of the control group (54.17%) (P<0.05). Conclusion Pre-hospital emergency care intervention for patients with acute cerebral hemorrhage can effectively shorten transit time, reduce complications and improve outcome and improve survival, worthy of promotion.

Objective To evaluate the changes of right ventricular (RV) volume and function by using single beat real-time three dimensional (3-D) echocardiography in patients with atrial septal defect (ASD) before and after percutaneous closure. Methods During the period from July 2011 to Oct. 2013, a total of 45 patients with pure ostium secundum defect were admitted to authors’ hospital to receive percutaneous transcatheter closer. The patients were divided into ASD without pulmonary hypertension (PH) group (group A, n = 28) and ASD with PH group (group B, n = 17). By using 3-D echocardiography and right cardiac catheterization, the right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular stroke volume (RVSV), right ventricular ejection fraction (RVEF), right ventricular cardiac output (RVCO), pulmonary artery systolic pressure (PASP) and the mean pulmonary artery pressure (mPAP) were determined before and after the percutaneous transcatheter closer. The results were compared between the two groups. Results After the treatment a statistically significant reduction in RVEDV, RVESV, RVSV and RVCO were seen in all patients (P < 0.05). In group A, RVEF decreased significantly after ASD closure when compared with that determined before transcatheter closer (P < 0.05), while no significant reduction in RVEF was seen in group B (P > 0.05). Pulmonary artery pressure (PAP) decreased significantly in group B after ASD closure when compared with that obtained before Objective To evaluate the changes of right ventricular (RV) volume and function by using single beat real-time three dimensional (3-D) echocardiography in patients with atrial septal defect (ASD) before and after percutaneous closure.

Objective To investigate the safety and longterm outcomes of prophylactic autologous pericardium tricuspid valve annuloplasty(TVA)in patients with rheumatic heart disease(RHD). Methods A total of 832 patients with RHD were enrolled in this study ,including 146 patients with mild FTR but without TVA(observation group);434 patients with mild FTR underwent TVA(control group A)and 434 patients with moderate or severe FTR underwent TVA(control group B). Propensity score and survival analysis were used to evaluate perioperative safety ,FTR progression ,CHF and MACCE incidence after prophylactic TVA. Results A total of 192 patients were successfully matched. There was no significant difference in the perioperative complications between the observation group and the control groups(P>0.05). The progression rate of FTR in the observation group was significantly lower than that in the control groups (P = 0.005 & 0.032 ). There was no significant difference in the incidence of CHF and MACCE events between the observation group and the control groups (P > 0.05). Conclusions The treatment strategy of prophylactic autologous pericardium TVA at the time of left heart valve surgery for patients with RHD doesn′t increase operation costs ,perioperative complications and mortality ,but effectively prevent postoperative FTR recurrence or progression.

OBJECTIVE: To explore the genetic basis for two children with sporadic neurofibromatosis type 1 (NF1) complicated with nephrotic syndrome (NS). METHODS: Clinical data of the children were collected. Both children were subjected to high-throughput sequencing, and candidate variants were verified by Sanger sequencing. RESULTS: Both children had café-au-lait macules, subaxillary freckle and Lisch nodules. Child 1 also had congenital tibiofibular pseudarthrosis on the left side. Genetic testing revealed that child 1 has harbored a heterozygous c.844C>T variant in the exon 8 of the NF1 gene, whilst child 2 has harbored a heterozygous c.1246C>T variant in the exon 11 of the NF1 gene. Both children were diagnosed with NF1 and have developed pronounced proteinuria, hypoalbuminemia, hypercholesterolemia and pitting edema at the ages of 3 and 10, respectively. Renal biopsy of child 2 has revealed minimal change nephropathy, and the diagnosis of nephrotic syndrome was established. Child 1 was treated with glucocorticoid, and child 2 was treated with glucocorticoid in combination with mycophenolate mofetil. The NS was relieved with no recurrence during 1 year's follow-up. CONCLUSION NF1 combined with NS is rare in the clinical settings. The prognosis of children with NF1 combined with minimal change nephropathy is relatively good. Detection of NF1 gene variant can facilitate early identification and diagnosis of NF1.
