Objective To investigate the pathogens of acute respiratory infection of children.Methods A total of 159 children with acute respiratory infection who were hospitalized in our department from August 2005 to January 2006 were involved in this study.The serum IgM antibody of 18 pathogens were detected by indirect immunofluorescence test.The 18 pathogens included respiratory syncytial virus(RSV),adenovirus(ADV),influenza A(H1N1,H3N2)and B viruses,parainfluenza viruses(PIV) type 1,2,3 and 4,coxsackie virus B1(CBV1),coxsackie virus A7(CAV7),echovirus(ECHO7),haemophilus influenzae(HI),klebsiella pneumoniae(KP),bordetella pertussis(BP),bordetella parapertussis(BPP) and legionella pneumophila serotype 1 and 12.Results The evidence of specific IgM was obtained in 103 of 159 patients(64.78%).Influenza A was found in 66 cases(64.08%),influenza B in 49 cases(47.57%),enterovirus in 26 cases(25.24%),RSV in 18 cases(17.48%),PIV in 11 cases(10.68%),and co-infection in 66 cases(64.08%),1/ 3 of them were co-infected with influenza A and B.Conclusions Viruses are the most common agents of acute respiratory infection.Influenza virus is predominant among them.

Objective To summarize and discuss the diagnostic and treating experiences of chronic pancreatitis with mass in the head. Methods Eight patients of chronic pancreatitis with mass in the head who were misdiagnosised as carcinoma of head of pancreas were analyzed retrospectively in the past 10 years. Results All the patients exhibited abdominal pain,5 of whom were with jaundice and 3 with anorexia. All the patients were misdiagnosised as carcinoma of head of pancreas before the operation,but the pathology after operation indicated chronic pancreatitis. The pancreaticoduodenectomy was performed in 5 patients,the choledochojejunostomy in 2 patients,while the exploratory laparotomy in 1 patient. After the operations,the abdominal pain was relieved in 7 patients, while 2 patients who accepted pancreatoduodenectomy suffered from pancreatic fistula,1 of whom died in the end. Conclusion It’s hard to differentiate the chronic pancreatitis with mass in the head from the carcinoma of head of pancreas before operation. If the carcinoma of head of pancreas can’t be excluded during the operation,the pancreatoduodenectomy should be performed,while the duodenum-preserving total resection of the head of the pancreas or any intra-drainage operations should be done if chronic inflammation is found in the whole pancreas with a negative result of the biopsy of the pancreas through the needle aspiration.

Objective To study the epidemiological and clinical characteristics of patients with severe acute respiratory syndrome(SARA). Methods Clinical data from 682 patients with SARS were retrospectively analyzed. Results The patients ranged from 13 to 76 years old, 387 male and 295 female. A total of 356 patients (52.2) had a history of close contact with diagnosed SARS patients, and 113 (25.1%) had been to hospital ever. The most common symptom was fever (99.3%), followed by cough (44.4%), shortness of breath (12.2% ), diarrhea (8.9%). 596 patients (87.4%) had normal or decreased white blood cell counts. Serum ALT and CPK levels were elevated in 112 patients (16.4%)and 17 patients (2.5%) respectively. Infiltrates on chest radiography were seen in all patients, with 69.8% involved both lungs. Six patients (0.9%) died of SARS. Conclusion SARS is infectious. Hospital is an important place where SARS transmits. Fever, cough and infiltrative changes on chest radiography are mainly symptoms and signs.

OBJECTIVETo evaluate the curative effect and surigical skills of reconstruction intramedullary nailing in the treatment of ipsilateral femoral neck and shaft fractures.

METHODSFrom January 2007 to January 2013, 13 patients with ipsilateral femoral neck and shaft fractures were treated by reconstruction intramedullary nailing including 11 males and 2 females with an average age of 38.9 yeas old ranging from 25 to 53 years old. For femoral neck fractures,10 cases were basilar neck fracture, 3 were transcervical fractures and according to Garden classification,10 were type II, 2 were type III and 1 was type IV. For feormal shaft fracture, 5 were type I, 4 were type II, 3 were type III and 1 was type IV according to Winquist classification. The location of all 13 feormal shaft fractures were all in the uper 3/4 of the feormal shaft. Complications and postoperative function were recorded and evaluated.

RESULTSEleven patients were followed up for 23.45 months (12 to 36 months). Time from injury to operation was 5.9 days in average. Malunion of femoral neck fracture happened in 1 patient, nonunion of femoral shaft fracture happened in 2 patients. NO femoral head osteonecrosis, infection and malunion of femoral shaft fracture happened. According to Friedman-Wyman classification, 8 cases get good result, 2 get faii and 1 get poor.

CONCLUSIONReconstruction intramedullary nailing is a good choice for the ipsilateral femoral neck and shaft fractures with the advantages of less soft-tissue trauma and complications.

OBJECTIVETo compare the efficacy of internal fixation (including PFNA and PFN) versus hip replacement (including FHR or THA) in the treatment of trochanteric fractures in adults.

METHODSReports of studies using randomized controlled trials (RCT) to compare internal fixationg with hip replacement in the management of intertrochanteric fractures were retrieved (up to January 1, 2013) from the Cochrane Library, PUBMED Data, CNKI (China National Knowledge infrastructure), Elsevier, the Chinese Biomedical Database, Wanfang Data, and manually. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software RevMan 5.0 was used for data-analysis.

RESULTSSeven articles were included in the meta-analysis. The results showed that,compared internal fixation with hip replacement,there were statistical significance in the duration of surgery time [WMD = -2.66, 95% CI (-5.25,-0.06), P = 0.05], intra-operative blood loss [WMD = -24.20, 95% CI (-30.38, -18.02), P < 0.000 01], hospital stays time [WMD = -4.72, 95% CI (-5.18, -4.25), P < 0.000 01], bearing load time [WMD = -29.54, 95% CI (-30.77, -28.31), P < 0.000 01], total complications rate [WMD = 0.15, 95% CI (0.11, 0.22), P < 0.000 01], the good rate of Harris scores [WMD = 1.09, 95% CI (0.54,1.32), P < 0.05]. However, there were no statistical significance in the rate of deep venous thrombosis [WMD = 1.09, 95% CI (0.47, 2.55), P > 0.05]. CON- CLUSION: Hip replacement (containing FHR or THA) for the treatment of intertrochanteric fractures is superior to internal fixa- tion in regards to the duration of surgery time, the mean duration of hosipital stays, mean post-operative down time, intra-opera- tive blood loss, the rate of post-operative good Harris scores. But there is not enough evidence to show any difference between hip replacement (containing THA or FHR) and internal fixation in regards to the rate of deep venous thrombosis. However, internal fixation for the treatment of intertrochanteric fractures is superior to hip replacement (containing FHR or THA) in regards to total complications rate.

Objective To investigate the changes of sympathovagal balance and the effects of va- gus stimulation on sympathovagal balance in endotoxemia rats.Methods Twenty-four Spragne Dawley rats were randomly divided into four groups.The frequency domain of heart rate variability(HRV)com- ponent was analyzed at 0 min,2 ,4 and 6 hours after intravenous injection of lipopolysaccharide(LPS, 5mg/kg)or physiologic saline,and cervical vagal nerve was stimulated(5mv,2ms,1Hz,5 min lasted, 20 min interval)when LPS or physiologic saline was injected.The levels of Noepinephine(NE)and Ace- tylcholin(ACh)were measured in liver tissues.Results Normalized low frequency(LFnm),hormali- zed high frequency(HFnm),very low frequency(VLF),LF/HF values and liver ACh were significantly increased(P＜0.05)and the level of liver NE was significantly decreased (P＜0.05)after LPS admin- istration.Vagal nerve stimulation markedly increased HFnm but decreased LFnm,VLF,LF/HF values, and the liver ACh also significant increased(P＜0.05 ).Conclusion The results suggest that the ac- tivity of sympathetic and vagal nerve was increased during endotoxemia,but the sympathetic activity was more excitable than that of vagal nerve.Vagal nerve stimulation increased the tone of vagus nerve while the tone of sympathetic nerve was decreased in this study.This may be beneficial for anti-inflammatory activity of vagal nerve.
