Objective To evaluate the effect of endoscopic sinus surgery (ESS) for treating fungal rhinosinusitis. Methods A total of 19 patients with fungal rhinosinusitis were treated under endoscope in this hospital from January 2000 to December 2003. In operation, the polyps or granulations in the middle nasal meatus were cleared away. Then after the removal of the uncinate process, all sinus ostiums were enlarged to further get rid of pathological tissues in the sinus. During the surgery the sinus was repeatedly irrigated with 3% H_2O_2. If the drainage of the sinus ostium had been affected by the narrowing of the middle meatus resulted from a deviation of the nasal septum, a synchronal correction of the nasal septum was carried out. Results Symptoms remitted in 5 patients and disappeared in 14 postoperatively. Follow-up for 6~48 months (mean, 14 months) in 19 patients found 2 patients with recurrence, which was re-operated on with the Caldwell-Luc procedure. No complications were observed. Conclusions The ESS is effective in the treatment of non-invasive fungal rhinosinusitis. However, this technique cannot replace the Caldwell-Luc procedure in the management of serious fungal maxillary sinusitis.

Hypoxic preconditioning improves organism in stress response such as operation.This dissertation expound the effects of hypoxic preconditioning on hepatic carcinoma after hepatic resection.Hypoxic preconditioning protect remainder hepatocyte from ischemia reperfusion injury in the remaining liver by regulating HIF-1,nuclear factor-kappa B and being kind to our mitochondria; remote-ectopic hypoxic preconditioning and cross-pluripotential hypoxic preconditioning preserve residual liver.Hypoxic preconditioning can relieve liver from ischemia reperfusion injury after hepatocellular carcinoma hepatectomy,but no clear evidence demonstrate it improve residual liver regeneration.This need further experimental study.

Objective To compare the effects of penequinine hydrochloride and atropine on the cardiovascu-lar stability about preoperative in children by monitoring and recording the HR, MAP, SpO2, ECG changes. Methods 40 children underwent selective operation were randomly divided into two groups, 20 in each group. Penequinine hydrechloride group(group A) and atropine group(group B) were injected intramuscularly with penequinine hydro-chloride 0. 015mg/kg or atropine 0. 015mg/kg respectively, at 30 minutes before operation. Patients' HR, MAP, SpO2 and ECG changes were recorded at 10min,20min,30min and 40min after injection. Results The HR,MAP,SpO2 levels of group A and SpO2 level of group B had no significant changes. There are significant changes in HR,MAP of group B. Conclusion Penequinine hydrochloride can be used as preoperative medication and it is conducive to the maintenance of cardiovascular stability.

Objective:To investigate the effect of survivin-siRNA plasmid on survivin expression in human lung cancer cell line A549, and to observe its effect on the apoptosis, proliferation, and chemosensitivity of A549 cells. Methods: pSilencer-survivin-siRNA (survivin-siRNA) plasmid was constructed using pSilencer-U6 plasmid and was transfected into A549 cells. Expression of survivin mRNA and protein was examined by RT-PCR and Western blotting analysis, respec-tively. Apoptosis and proliferation of A549 cells were examined by DAPI staining and MTT, respectively. Results: Sur-vivin-siRNA plasmid was successfully constructed, and it significantly inhibited survivin mRNA and protein expression in A549 cells. Survivin-siRNA transfection induced apoptosis, inhibited proliferation and increased chemosensitivity of A549 cells to cisplatin. Conclusion: pSilencer-survivin-siRNA can silence survivin expression in A549 cells and subsequently inhibit proliferation, promote apoptosis, and enhance chemosensitivity of A549 cells to cisplatin. Survivin may serve as a potential target for gene therapy of lung cancer.

Objective To study the prognostic value of procalcitonin (PCT) level in the outcome of patients with paraquat poisoning (PQ).Methods The clinical data of 128 patients with acute PQ admitted to emergency department were collected from March 2013 through March 2014.The patients were divided into two groups:the death group and the survival group (survival of 28 days).Poisoning doses,urine concentration of PQ,time elapsed from poisoning to admission,and time elapsed from poisoning to gastrolavage were documented.And on the 1 st day,the 3rd day and the 7th day after poisoning,serum PCT were detected.The level of PCT was used to investigate the prognostic values in patients with acute PQ in the death group and survival group.Results Of 128 cases,72 (56.3％) survived and 56 died in 28 days.Among them,the level of PCT increased to some extent in the first day in 90 cases,and 48 patients died.According to trend analysis,the levels of PCT in death group on the 1st day,the 3rd day and the 7th day after PQ were significantly higher than those in survival group [ld:(0.96 ±0.13) vs.(0.08 ±0.01),3d:(1.12 ±0.14) vs.(0.28 ±0.05),7d:(1.22 ±0.14) vs.(0.20 ±0.03),P ＜0.01].There was a trend of escalating PCT levels in death group,whereas the PCT level reached the peak on the 3st day and decreased gradually in the following days in survival group.The early PCT level was obviously related to poisoning doses,urine concentration,CRP,WBC,ALT,CR (the coefficient of association were 0.794,0.723,0.724,0.332,0.700,0.414,respectively,P＜0.01).Conclusions The serum level of PCT increased in patients with acute PQ was significantly positively correlated with the oral dose and urine concentration of paraquat,and it can be used as an indicator for PQ severity.There is important clinical significance in detecting the change of serum level of PCT for estimating the condition of patients and evaluating the prognosis.

Objective To investigate the influence of IVIG on immunologic function and cytokines levels in children with EV71 infection associated high-risk pulmonary hemorrhage. Methods According to the inclu-sion criteria , 64 children were enrolled and randomly divided into two groups: 39 cases in the IVIG treatment group and 25 cases in the general treatment group. The alternations of blood and immune cytokine markers before and after treatment were detected in the patients. Results (1) Before treatment, the peripheral blood T cells, TH and B cells in the IVIG group were higher than those in the general group , but the peripheral blood IgA was lower than that in the general group(P < 0.05); (2) In the IVIG group, the NK cells and IgG increased and T cells, TH cell and B cells significantly decreased after receiving IVIG therapy (P < 0.05); (3)No significant difference was observed in the levels of IL-6 and IL-10 in the two treatment groups before treatment. However , after IVIG treatment, IL-6 and IFN-γ levels reduced, IL-10 level increased (P < 0.05). After the general treat-ment, no significant difference was found in levels of IL-6,IL-10 and IFN-γ in peripheral blood (P > 0.05). Conclusion Disorders of cellular immunity and humoral immunity appeared in children with EV71 infection-re-lated high-risk pulmonary hemorrhage. It has clinical value to use IVIG timely to regulate the immune disorder.

Objective To evaluate the prospective electrocardiograph (ECG)-gated 128-slice spiral CT angiography in the diagnosis of complex congenital heart disease and airway abnormality in children.Methods Eighty children with congenital heart disease received prospective (n =40) or retrospective ECG-gated 128-slice spiral CT angiography (n =40).All of the patients underwent ultrasound cardiogram (UCG) within one week before CTA exmination.The image quality and the effective radiation dose were statistically analyzed using independent samples t test and x2 test.The surgical results were taken as the diagnostic standards,and the preoperative prospective and retrospective CT angiography data were compared with UCG results using x2 test.Results The effective dose of prospective ECG-gated CT angiography[(1.00 ± 0.26)mSv] was reduced by 86％ as compared with the retrospective ECG-gated CT angiography[(7.37 ± 0.52) mSv] (t =69.296,P ＜ 0.01).Image quality was graded 0 in none patients,graded 1 in 2 patients who underwent prospective ECG-gated CT angiography,graded 2 in 8 and 1 patient who received prospective and retrospective ECG-gated CT angiography respectively,and graded 3 in 30 and 39 patients who underwent prospective and retrospective ECG-gated CT angiography,respectively.There was no significant difference in image quality between prospective and retrospective ECG-gated CT angiography (x2 =0.044,P ＞ 0.05).The definitive diagnosis of extracardiac vascular anomalies was made in 98.3％(59/60) of patients by using prospective and retrospective ECG-gated CT angiography,which were significantly superior to UCG results[(76.7％ (46/60),76.7％ (45/59),respectively] (x2 =13.144,12.644,P ＜ 0.01),and there was no significant difference in the definitive diagnosis between prospective and retrospective ECG-gated CT angiography (x2 =0.001,P ＞ 0.05).The definitive diagnosis of the cardiac/large-vessel malformations was made in 100％ of the patients by both prospective and retrospective ECG-gated CT angiography,and there was no significant difference between 128-slice spiral CT angiography results and UCG results [97.2％ (35/36),97.3％ (36/37),respectively] (x2 =1.014,0.001,P ＞0.05).In the cardiac malformations,the definitive diagnosis by prospective and retrospective ECG-gated CT angiography was 88.7 ％ (47/53) and 92.5 ％ (49/53),and there was no significant difference between 128-slice spiral CT angiography results and UCG results [98.1％ (52/53),98.1％ (52/53),respectively](x2 =3.824,1.889,P ＞ 0.05),and no significant difference in the definitive diagnosis was observed between prospective and retrospective ECG-gated CT angiography (x2 =0.442,P ＞ 0.05).In addition,the 128-slice spiral CT angiography detected airway abnormality in 9 cases who underwent prospective or retrospective ECG-gated CT angiography.Conclusion The prospective ECG-gated 128-slice spiral CT angiography exhibits great application value in the preoperative diagnosis of complex congenital heart disease,which helps to develop surgical program and evaluate surgical risks.

Objective To investigate the effect of Heat shock protein 70 induced by hypoxic precondition on apoptosis of the remnant livers after the hepatectomy of transplanted hepatic cancer models in SD rants and it's possible mechanisms.Methods Sixty SD rats of transplanted hepatic cancer models were divided into group A (sham operation group),group B (IR + hepatectomy group),and group C (hypoxia precondition + IR + hepatectomy group),with 20 rats in each group.C group was given 10％ oxygen atmosphere for 90 minutes before operation,In 15 minutes of hepatic vascular occlusion with pringle method,Left lateral of liver which tumor was located was resected.At 1,8,12,24 hours after operation,Five rats of each group were killed respectively,then the remnant liver tissues were sampled to measured the hepatocytes apoptosis rate with flow cytometry,expression of heat shock protein 70 (HSP70) and Bax were detected by Western blotting.The serum AST and ALT activities were measured by an automatic analyzer.The histological changes of the hepatocytes were also observed by optical microscopy.All the data were statistically analyzed.Results (1) Compared with A and B group,the HSP70 expression increased obviously in C group at each time point (all P ＜ 0.05).The protein showed a weak expression in group A and B group,while the index had no significant differences between two groups (P ＞ 0.05).(2) In B group compared with A group,the expression of Bax and the hepatocytes apoptosis rate were significantly increased (all P ＜ 0.01 or P ＜0.05).However,amplitudes of the above changes in C group were significantly lower than those of B group (all P ＜ 0.05).(3)The liver function was improved in group HP.The pathological examination showed that the liver tissues in A group were general normal and in C group were showed mild changes,but in B group presented evident pathological changes.Conclusions HP can protect against ischemia-reperfusion injury after the hepatectomy of transplanted hepatic cancer models in SD rants,one of possible mechanisms is that HP can induce HSP70 expression at great intensity,which may decrease expression of Bax protein and the apoptosis of hepatocytes.
