Objective To explore the ellnieal effect of the diagnosis and the treatment of the disease in cer-vix of the uterus by LEEP with the help of eolposcopy. Methods 268 women with different kinds of disease in cervix of the uterus were selected, which were preliminarily diagnosed by gynecological examination, the examination of the exfoliative cells of cervix of the uterus, the examination by colposeope and the biopsy. LEEP surgery was used to treat them, and we carried out pathological examination of the surgery specimen and watched the time of operation, the a-mount of bleed and the effect of treatment. Results The average time is 5.8min, the average amount of bleeding is 6.7ml. No secondary infection. The dear diagnosis is determined by pathological exmaination of surgery specimens. Conclusion The operation is simple,safe,short operation time and less bleeding by LEEP surgery with the help of colposcope, and less water after the operation. It has good effect and can provide complete pathological specimen. Be-aides,the diagnosis can be taken simtdtaneously when treatment.

Objective To explore the dose-effect relationship and optimal concentration of sodium taurocholate (NaTc) to establish acute necrosis pancreatitis (ANP) complicating MODS in a rat. Methods 280 SD rats were randomly divided into control group (n =40) and 3.5%, 4%, 4.5%, 5% ANP group (n = 60, respectively). ANP groups were induced by retrograde injection of NaTc solution into the pancreatic duct of rats. Rats in each model group were sacrificed at 1, 3, 6, 12 and 24 h after the model induction. Serum amylase, serum total bilirubin, creatinine, blood gas analysis, and pathological changes of pancreas were determined. Survival rate at 24 h after the model induction was observed in other 20 ANP rats in each group. Results In each groups, the serum amylase level, creatinine, blood gas analysis and pathological changes all increased corresponding to the increase of NaTc, and there was significant dose-effect relationship and time-effect. In 4.5% group, the dysfunction of liver and kidney reached the peak at 6 h,while the respiratory dysfunction reached its peak at 12 h. Its incidence of MODS was 52.5%, which was significantly higher than those in 3.5%, 4.0% group (15.0% and 37.5%) ;and 24 h survival rate of 4.5% group was 65%, which was significantly higher than that in 5% group (30%). Conclusions 4.5% NaTc solution may be the optimal concentration to establish the ANP model, which had higher incidence of MODS and 24 h survival rate.

Objective To investigate the time-course change of intra-abdominal pressure (IAP), TNF-α in rat with acute necrotizing pancreatitis (ANP) and its mechanism. Methods 80 SD rats were randomly divided into ANP group and control group. ANP group was induced by retrograde injection of 4.5% sodium taurocholate into the pancreatic duct in SD rats, while control group was induced by injection of saline at the same dosage. Eight rats in each group were killed at 1 h, 3 h, 6 h, 12 h and 24 h, respectively. The serum levels of amylase, TNF-α were determined;IAP, amount of abdominal ascites, pancreatic pathologic changes were evaluated. Results The levels of amylase in ANP group increased progressively with time, which were 32-folds higher than those in control group at 24 h. The serum levels of TNF-α in ANP group reached the peak at 6 h, and were significantly higher than those in the control group. The amount of abdominal ascites increased post-ANP induction and reached the peak at 24 h, which was 4.7-folds higher than that in the control group. The IAP significantly increased 1 h after induction, which was 3 times as high as the control group in 3 h group and 9 times in 12 h group. Pathologic injuries deteriorated progressively and reached the peak at 24 h. Conclusions Significant IAP occurred in ANP rats and reached the peak at 12 h, TNF-α reached the peak at 6 h, therefore IAP may be the secondary response to inflammatory reaction.

Objective To evaluate the role of silent information regulator fac tor 2-related enzyme 1 (SIRT1)/Forkhead Box O3 (FoxO3a) signaling pathway in berberine pretreatment-induced reduction of hypoxia/reoxygenation (H/R)-caused injury to hepatic parenchymnal cells.Methods Hepatic parenchymal cells obtained from AML12 mice were cultured and seeded in 6-well plates (2 ml/well) and in 96-well plates (200 μl/well) at the density of l×l06 cells/ml.The cells were divided into 4 groups (n=36 each)using a randomn number table:control group (group C),group H/R,berberine pretreatment group (group BP) and SIRT1-siRNA group (group SS).The cells were cultured in normal culture atmosphere (5％ CO2-21％ O2-74％ N2) in group C.In H/R,BP and SS groups,the cells were exposed to hypoxic air (5％ CO2-1％ O2-94％ N2) for 12 h,followed by 6 h reoxygenation in normal culture atmosphere (5％ CO2-21％ O2-74％ N2).In group SS,small interference RNA targeting SIRT1 (SIRT1-siRNA) was added to the culture medium at 24 h prior to hypoxia.Berberine (final concentration 5 μmol/L) was added at 2 h prior to hypoxia in BP and SS groups.At the end of reoxygenation,the cell viability was measured by methyl thiazolyl tetrazolium assay,the malondialdehyde (MDA) content and superoxide dismutase (SOD) activity were determined using enzyme-linked immunosorbent assay,cell apoptosis was detected by flow cytometry,the expression of SIRT1 and FoxO3α was detected by Western blot,and the acetylation of FoxO3α was measnred by using immunoprecipitation.Apoptotic rate was calculated.Results Compared with group C,the cell viability was significantly decreased,the MDA content was increased,the SOD activity was decreased,apoptotic rate was increased,the expression of SIRT1 and ratio of FoxO3α expression in nucleus/in cytoplasma were increased,and the acetylation of FoxO3α in the nucleus was increased in H/ R,BP and SS groups (P＜ 0.05).Compared with group H/R,the cell viability was significantly increased,the MDA content was decreased,the SOD activity was increased,apoptotic rate was decreased,the expression of SIRT1 and ratio of FoxO3α expression in nucleus/in cytoplasma were increased,and the acetylation of FoxO3α in the nucleus was increased in group BP (P＜0.05).Compared with group BP,the cell viability was significantly decreased,the MDA content was increased,the SOD activity was decreased,apoptotic rate was increased,the expression of SIRT1 and ratio of FoxO3α expression in nucleus/in cytoplasma were decreased,and the acetylation of FoxO3α in the nucleus was decreased in group SS (P＜O.05).Conclusion The mechanism by which berberine pretreatment attenuates H/R-caused injury to hepatic parenchymal cells is related to promotion of SIRT1 expression in cells and inhibition of FoxO3α acetylation in the nucleus.

Objective To evaluate the relationship between sternum protection and bone marrow suppression in postoperative radiotherapy for esophageal carcinoma. Methods Total of 98 postoperative patients with thoracic esophageal carcinoma were randomly divided into experimental group (52 cases) and control group (46 cases). All patients were given intensity-modulated radiotherapy (IMRT), with the dose of 50-50.4 Gy. The patients in experimental group were irradiated by 6 fields (4-fields in front, 2-fields behind) which were crossed to avoid direct exposure to the sternum. The patients in control group were irradiated by 5 fields (3-fields in front, 2-fields behind) with front-middle of the field passing through the sternum. Concurrently all patients received 2 cycles of cisplatin chemotherapy. Results Dmean, V20 and V30 of the sternum in the experimental group were (20.21 ±3.60) Gy, (40.78 ±7.19) % and (33.78 ±9.44) %, which were lower than those in the control group [(30.91±5.21) Gy, (81.01±4.81) %, (51.60±6.84) %], respectively (P<0.05). However, the volume and dose distribution of lung, spinal cord and heart were similar between the two groups (P> 0.05). Both the incidence rates of bone marrow suppression at 14th day and 35th day after radiotherapy were significantly higher in the control group (52.2%, 73.9%) than those in the experimental group (28.8 %, 50.0 %) (P< 0.05), and the incidence rate of bone marrow suppression at 7th day after radiotherapy was similar between the two groups. Conclusion Protecting and sketching for sternum in postoperative radiotherapy for esophageal carcinoma can reduce the incidence of bone marrow suppression effectively, which would not increase the radiation dose in the lung, heart and spinal cord.

Objective To investigate the efficacy of initial polytherapy in the patients with newly diagnosed infantile spasm by evaluating the ambulatory electronecephalogram (EEG) profiles and serum neuron specific enolase ( NSE ) level.Methods Data from 108 cases of newly diagnosed infantile spasm from Sep.2007 to Nov.2010 in the Department of Pediatrics,the First Hospital of Jilin University,were respectively analyzed for the EEG profiles and serum NSE level.The patients were treated with multiple drugs.Results ( 1 )After treatment,EEG showed normal shape in 56 cases ( 62.2％ ),sporadic sharp and slow waves without hypsarrhythmia in 32 cases( 35.6％ ),and hypsarrhythmia in 2 cases (2.2％).The overall effective rate was 97.8％.(2) Serum NSE in 35 seizure-free cases were examined at the time points of hospital admission,48 hours and one month after seizure cessation,respectively.NSE level was significantly decreased at 48 hours after seizure control than that at hospital admission ( t =6.54,P ＜ 0.05 ) ; NSE at one month after seizure free was further decreased compared with that at admission point ( t =9.29,P ＜ 0.05 ).Conclusion Polytherapy for infantile spasms can ameliorate the abnormal EEGs.NSE level is decreased after seizure cessation.Intelligence is improved 6 months after seizure free and polytherapy may improve the prognosis of the children with infantile spasms.

Fed with high-fat diet and assessed by hyperinsulinemia-euglycemia clamp technique, rat models with insulin resistance were successfully induced. Compared with normal chow group ( NC ), serum concentrations of free-fatty acids(FFAs) and baseline insulin in high-fat diet group(HF) was higher( P＜0.05 ), the average glucose infusion rate from 60 to 120 min( GIR60-120 ) was lower( P＜0.01 ), and the expression of p-IRE-lα in the liver was higher( P＜0.05 ). Furthermore, the expression of p-IRE-1α in the liver was positvely correlated with the serum concentration of FFAs. All these data indicate that high-fat diet may induce endoplasmic reticulum stress in the liver by elevating serum concentration of FFAs, and may participate in the genesis of insulin resistance via p-IRE-1α.
