This article introduced the experiences of nongovernmental capital running hospitals in US,Germany,India and Israel and put forward some suggestions that need to be considered in China, such as innovating supply model of health care service,treating social capital running hospitals equally and strengthening supervision.

Objective To evaluate the kinetics of peripheral blood cells in DTC patients before and after 131I treatment.Methods A total of 64 patients were divided into 2 groups with different therapeutic doses:high-dose group (3.70-5.55 GBq,n =24) and low-dose group (1.11 GBq,n =40).The WBC,neutrophils (NEUT),lymphocytes (LY),RBC and PLT were counted before operation,before 131I treatment,and on 3 d and 7 d after 131I treatment.One-way analysis of variance and two-sample t test were used to analyze the data.Results The counts of WBC and NEUT in both groups along with the LY in high-dose group varied significantly before,and on 3 d and 7 d after 131I treatment(WBC:high-dose group,(6.30±1.04),(8.86±2.07),(6.59±1.64) × 109/L;low-dose group,(6.65±1.48),(10.17±3.04),(7.17± 1.57) ×109/L; NEUT:high-dose group,(3.75±0.88),(6.42± 1.91),(4.53± 1.54) × 109/L; low-dose group,(3.88±0.90),(7.12±2.77),(4.40±1.17) × 109/L;LY:(2.11±0.67),(2.06±0.74),(1.59±0.49) × 109/L;F values:3.88 to 30.20,all P＜0.05).The counts of WBC and NEUT in both groups were significantly higher on 3 d after 131I treatment than that before treatment (all P＜0.05).The counts of WBC and NEUT in both groups along with the LY in high-dose group decreased significantly on 7 d compared to that on 3 d after 131I treatment (all P＜0.05).The counts of LY in high-dose group also significantly decreased on 7 d after 131I treatment than before treatment(P＜0.05).The counts of RBC before 131I treatment and LY on 7 d after 131I treatment were significantly different between the 2 groups(t=2.36,-4.30,both P＜0.05).Compared with the counts before operation,LY,RBC and PLT were significantly higher (t values:from-4.92 to-2.45,all P＜0.05) during hypothyroid state induced by thyroxine withdrawal before 131I treatment.Conclusions Short-term kinetics of WBC and NEUT present as an increase first followed by a decrease after 131I treatment; while LY of high-dose group presents as a gradually decrease.Hypothyroid state induced by levo-thyroxine withdrawal leads to increased counts of LY,RBC and PLT before 131I treatment.

Objective To analyze the etiology in pancreatic pseudocyst (PPC). Methods Medical records were reviewed and analyzed for 366 PPC patients who were admitted in Changhai hospitals from April 2000 to December 2009 in terms. Demographic data, etiology and primary disorders of PPC patients were recorded. Results The causes of 366 patients varied as follow: gallstones in 158 patients (43.2%);idiopathic in 79 (21.6%); alcohol in 50 (13.7%); trauma in 17 (4.6%); pancreatic tumor in 9 (2.5%);hyperlipidemia in 8 (2.2%); post-operative in 7 (1.9%), other in 38 (10.3%). Depending on Atlantes classification systerm the PPCs were classified into acute PPC in 204 patients (64.2%), chronic PPC in 98 patients (30.8%) and abscess in 16 patients (5.0%). The 4 most common causes of acute PPC were gallstones, idiopathic, alcohol and trauma; the 3 most common causes of chronic PPC were gallstones,idiopathic, alcohol. Conclusions Gallstones is the main etiologic cause of the PPCs in China, followed by idiopathic and alcohol, which is significantly different with that in Western countries.

Objective To investigate the expressions of CXCR4 in Barrett esophagus (BE), esophageal adenocarcinoma (EADC) and esophageal squamous cell carcinoma (ESCC), and its relationship with pathology, clinical staging and lymph node metastasis. Methods The expressions of CXCR4 in 56 cases of normal esophageal mucosa, 80 BE (including 22 BE with multifocal dysplasia), 25 EADC and 48 ESCC were examined with immunohistochemical method. Results CXCR4 was expressed in most samples of BE (80. 8% ), EADC (68. 0% ) and ESCC (78.4%) without significant difference ( P ＞ 0. 05 ), which was significantly higher than that in normal esophageal mucosa (39. 3%, P ＜0. 01 ). The level of CXCR4 expression in BE, EADC or ESCC were not related with gender, age, or location of the foci ( P ＞ 0. 05). There was no significant difference in CXCR4 expression between BE without dysplasia or BE with multifocal dysplasia ( P ＞ 0. 05 ). CXCR4 expression level in well-differentiated EADC was significantly higher than that of mild or poorly differentiated (P ＜ 0. 05 ). CXCR4 expression level was higher in EADC with lymph node metastasis than those without ( P ＜ 0. 05 ). CXCR4 level in ESCC with TNM staging grades Ⅲ -Ⅳ was higher than that of grades Ⅰ - Ⅱ, and this variable was also higher in cases with lymph node metastasis than those without (P ＜ 0. 05), so was the case of well and poorly differentiated ESCC (P ＜ 0. 01 ). Conclusion Increased expression level of CXCR4 may be a common feature of EADC and ESCC, which is irrelevant to pathological types. CXCR4 level rises at the stage of BE, which is associated with the degree of tumor differentiation, lymph node metastasis and TNM staging. CXCR4 expression is of guiding significance in the diagnosis of BE, EADC and ESCC, and is the potential drug target.

Objective To explore the clinical effects of atlantoaxial pedicle screw instrumentation in treatment of intractable atlantoaxial dislocation in children. Methods A total of 7 patients with intractable atlantoaxial dislocations were treated with aflantoaxial pedicle screw instrumentation plus atlantoaxial bone grafting from June 2002 to January 2001. Results The dislocation in all patients reached complete reduction, with no complications. All patients were followed up for average 10 months (8-14 months). Radiographs showed successful bone fusion in all patients. Conclusion Atlantoaxial pedicle screw fixation and fusion is an effective method for treatment of intractable atlantoaxial dislocation in chil dren.

Objective To investigate the risk factors for nosoeomial pneumonia in elderly stroke patients(aged 60 years and over). Methods The clinical data of 259 patients with nosoeomial pneumonia from Jan 2002 to June 2007 were collected and the risk factors were retrospectively analyzed. Results The morbility rate of nosocomial pneumonia in elderly stroke patients was 41.3%,and the risk factors were aging,Iong hospitalization,unconsciousness,type of stroke,and underlying diseases,smoking,tracheal intubation,tracheotomy,application of respiratory machine (all P＞0.05). Conclusions The morbility rate of nosoeomial pneumonia in elderly stroke patients was high,and the risk factors are aging,long hospitalization,unconsciousness,type of stroke,and underlying diseases,smoking,tracheal intubation,tracheotomy,application of respiratory machine.
