Legg-Calvé-Perthes disease is one of the most concerned hip diseases in the pediatric orthopaedic field.Although there are many treatments for Legg-Calvé-Perthes disease,new ideas for the therapy of Legg-Calvé-Perthes disease still exist.Moreover,the prognosis of the disease mostly focuses on the studies of the degree of involvement of the epiphyseal plate,age of onset and lateral pillar classification.This contribution summarizes the treatments and prognosis of Legg-Calvé-Perthes disease.

Objective:To study the role of basic fibroblast growth f ac tor (bFGF) on angiogenesis in oral squamous cell carcinoma(OSCC).Methods :Expression of bFGF and CD34 in 42 cases of OSCC(14 cases with lymph no de metastasis) and 10 cases of normal oral mucosa(NOM) was detected by immunohis tochemistry. Microvessel density(MVD) in OSCC was assessed with microscope. Results:bFGF was detected in 29(69.05%) cases of OSCC and in 3(33.3 3%) of NOM. MVD in OSCC and NOM was 53.50?9.59 and 23.30?7.33(P

Objective To research the cardioprotective effect of Astragalus Membranaceus Polysaccharide (AMP) on hemodynamic and oxygen free radicals in myocardial ischemia followed by reperfusion. Methods By using experimental rats cardiac model, rats were divided into 3 groups:CG (control group), IR (Ischemia-Referpusion) and AMP (Astragalus Membranaceus Polysaccharide). Results AMP could promote the restoration of LVSP、?dp/dtmax、CF、CO、SV、SI、CI, and decrease the rising of LVEDP and T value distinctively. The recovery of left ventricular function in AMP group was better than that of the ischemia-reperfusion group, which was accompanied with the significant reduction of oxygen free radicals and increase of superoxide dismutase. Conclusion AMP could attenuate ischemia- reperfusion injury and ameliorate functional recovery in isolated rat hearts.

Objective To analyze the misdiagnosis in extraovarian peritoneal carcinoma(EOPC). Methods The clinical manifestation, blood tumor marker, imaging examination, laparotomy, pathology, treatment and prognosis of 19 EOPC patients were retrospectively analyzed. Results The clinical symptoms were abdominal distention, abdominal pain and swelling. 17 cases were tested for blood CA-125 with 15 at abnormaly high level, and in 4 cases ascites was CA-125 positive ( ＞ 10 KU/L). Tumor cells were detected in the ascites in 12 cases. Three cases were misdiagnosed as of uterine origin, 13 cases misdiagnosed as adnexal tumor, 1 case was misdiagnosed as bladder and intestinal tumor. Only 2 cases were correctly diagnosed before the operation. All of the cases were pathologically proved as peritoneal carcinoma. The five-year survival rate was only 20 percent. Conclusions Abdominal distention and pain with unknown causes were the primary manifestations of EOPC, elaborate physical examination sometimes may provide with important information. The significant elevation of serum CA-125 and the ascites cytology may be helpul for the differential diagnosis of PPC. CT scan is valuable for the diagnosis of EOPC.

Objective To observe the clinical characteristics, risk factors, and sensitivity to antibiotics of nosocomial infections caused by acinetobacter baumannii. Methods Data were retrospectively collected from all isolated 37 strains acinetobacter. The clinical features, results of suptum culture and test of drug sensitivity were reviewed. Results The 37 acinetobacter baumannii strains mainly distributed in intensive care unit (ICU), most of them had the risk factors of receiving invasive treatment, mechanical ventilation, ect. The antibiotics imipenem, amikacin, pipercillin/tazobactam showed good efficacy for patients with acinetobacter infection, but other antibiotics had highly drug resistant rate. 5 were dead. The mortality of nosocomial infections caused by multi-drug resistant acinetobacter was 41.7%, which was much higher than the non-multi-drug resistant's (2 dead, the mortality was 8%). Conclusion Acinetobacter is one of the most important multi-drug resistant pathogen in nosocomial infections. Antimicrobial agents should be chosen according to antimicrobial susceptibility teat results. Patients who have the risk factors of nosocomial infections caused by acinetobacter should have suptum culture and antibiotic susceptibility studies as soon as possible.

OBJECTIVE:To study the protective effect of butylphthalide on the apoptosis of human umbilical vein endothelial cells (HUVECs) induced by Aβ1-42 and its mechanism. METHODS:HUVECs were divided into normal control group,Aβ1-42 group,TAK242 group(10 nmol/L),DMSO group(1‰DMSO)and butylphthalide low-concentration,medium-concentration and high-concentration groups (40,80,160 μg/L). Except for normal control group and DMSO group,other groups were given 50 μmol/L Aβ1-42 to culture HUVECs for 24 h. TAK242 group,DMSO group and butylphthalide low-concentration,medium-concentra-tion and high-concentration groups were given relevant concentration of drugs for 30 min,with 3 holes for each concentration. The cell viability was determined by CCK-8 assay;cell apoptosis was observed by Hochest 33342/PI double staining;the cell apoptotic rate was detected by AnnexinⅤ-fluorescein isothiocyanate (FITC) flow cytometry;the protein expression of TLR-4 and COX-2 were determined by Western blot assay;the contents of IL-1 and TNF-α were detected by ELISA. RESULTS:Compared with nor-mal control group,cell viability of HUVECs were decreased in Aβ1-42 group;while apoptotic rate,protein expression of TLR4 and COX-2,the contents of IL-1 and TNF-α were increased. Compared with Aβ1-42 group,cell viability of HUVECs were increased in TAK242 group and butylphthalide low-concentration,medium-concentration and high-concentration groups;while apoptotic rate, protein expression of TLR4 and COX-2,the contents of IL-1 and TNF-α were decreased,with statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Butylphthalide can reduce HUVECs apoptosis induced by Aβ1-42,which may be related with inhibiting the expression of TLR4,COX-2 and inflammatory factors.

Objective To study the effects of salt and cooking oil intervention among hypertensive patients on knowledge-attitude-practice. Method Three thousand hypertensive patients from 20 community health service centers in Shenzhen were chosen by multi-stage cluster random sampling method. Salt measuring spoons and scaled oil pots were provided during six-month health intervention. Before and after the six-months health intervention, 2 976 and 2 864 valid questionnaires were collected respectively. After intervention, 40 families were randomly selected to perform an investigation of cooking oil and salt weighing during 3 d 24 h. Result Before the intervention, the rates of awareness on the intake of salt and cooking oil were 29.94% and 16.23% respectively. After intervention, the rates increased to 88.58% (P<0.000 1) and 84.29%(P<0.000 1) respectively. The rates of restriction on the intake of salt and cooking oil were 62.97% and 59.07%, respectively, after the intervention, the rates were 97.14% and 96.79% (P<0.000 1), respectively. By using the salt measuring spoons and scaled oil pots, the intake of cooking oil and salt reached the recommended amount in Chinese dietary guideline. Conclusion The implementation of health education combined with appropriate tools could promote the knowledge and behavior of the salt and cooking oil consumption.

Objective To investigate the effect of integrated swallowing function rehabilitation training on nasal feeding patients with pseudobulbar palsy or bulbar palsy after acute ischemic stroke. Methods A total of 54 patients met the diagnosis criteria were enrolled prospectively. They were divided into either an integrated group (n=31)or a control group (n=23)using a random number table method. The patients of the control group received routine treatment of stroke,including brain protection therapy,improvement of cerebral circulation,dehydration,regulating blood pressure,and symptomatic treatment,etc;in addition to conventional treatment,those of the integrated group also received integrated swallowing function rehabilitation training,including neuromuscular electrical stimulation plus swallowing reflex facilitation technique,and oral facial glossopharyngeal function training,etc. The oral intake function in patients of the integration and pseudobulbar palsy or bulbar palsy (according to MRI and signs)was compared between the two groups. The evaluation index was the Functional Oral Intake Scale (FOIS)score. Results (1)The FOIS score (median 4)of the integrated group was higher than that of the control group (median 2). There was significant difference between the two groups (P<0. 01). There was also significant difference before and after comparison between the two groups. (2)The FOIS score of pseudobulbar palsy in the integrated group was higher than that of the control group (median scores 4 and 2 ). There was significant difference (P<0.01);There was no significant difference in the FOIS scores of bulbar palsy between the two groups,but the FOIS score of the integrated group was higher than that of the control group (median scores 4 and 3). (3)The median differences between the integrated group and the control group were 2 and 1 respectively. The increased amplitude of FOIS of the integrated group was higher than that of the control group. There was significant difference (P<0. 01). Conclusion The integrated swallowing function rehabilitation training can improve the oral intake function,significantly reduce irritating cough,increase the capacity of oral intake,and increase the types of food. The effect of the improvement of pseudobulbar palsy is more significant in the integrated group.
