Objective To explore the effects of sepsis on the ultrastructure and function of thyroid in rats.Methods This study was performed in the Animal Department of Fujian Medical University,the Key Laboratory of Fujian Provincial Cardiovascular Institute and the Electron.Microscopic Department of Fujian Medical University.Thirty-two pathogen-free male Sprague-Dawley rats weighing 180-220 g selected,and were randomly (random number) divided into control group (C group,n =8),12 hour group (n =8),24 hour group (n =8) and 36 hour group (n =8).The 12 h group,24 h group and 36 h group were established to be sepsis groups.The sepsis model was made by cecal ligation and puncture (CLP).The samples of blood and thyroid tissue of rats in 12 h group were taken 12 hours after modeling,and then the same procedure was done in the rats of 24 h group and 36 h group separately 24 hours and 36 hours after modeling.Blood serum was obtained by centrifugation to detect the thyroid function using measurement of different of kinds of hormones (T3,T4,fT3,fT4,TSH).Thyroid tissue was available to determine the expression of caspase-3,cell apoptosis and change of ultra-microstructure.Raw data were analyzed using SPSS19.0 software.Caspase-3 grey value was determined by Image J software.Thyroid hormone levels were presented as mean ± standard deviation.The differences in levels of different kinds of thyroid hormone among all the groups were determined by one-way ANOVA.TUNEL positive staining and caspase-3 expression were presented as median (P25,P75).Results Compared to the control group,the T4 decreased significantly (P＜0.05) in the 12 h group,the 24 h group and the 36 h group,both the tT3 and the fT4 decreased significantly in the 24 h group and the 36 h group (P ＜0.05),and the T3 decreased significantly in the 36 h group (P ＜ 0.05).The expression of caspase-3 in the 24 h group was higher than that in the C group (P ＜ 0.05).There was significant difference in rate of celt apoptosis in thyroid tissue among those four groups,and both the 24 h group and the 36 h group had higher rate of cell apoptosis than the C group significantly (P ＜0.05).In those sepsis groups,a series of pathological ultrastructural changes were found in thyroid follicular epithelial cells as following:the nucleus became smaller and more distinctly stained,and quite a few vacuoles were visualized in cell.Furthermore,the cell membrane was broken,and nuclei showed pyknosis.Conionclus In sepsis rats,the significant changes of different kinds of thyroid hormone in serum are similar to those found in the thyroidal illness syndrome,the expression of caspase-3 and cell apoptosis in thyroid tissue increase,and pathological change of thyroid follicular epithelial cells can be observed under electron microscopy.

Objective To explore the clinical characteristics of multiple organs dysfunction syndrome (MODS) complicated with injury of pancreas.Methods A prospective study was carried out.From January 2011 to December 2012,a total of 69 patients with MODS in Department of Medical Intensie Care Unit,Fujian Provincial Hospital,Fujian Medical University were divided into 2 groups at admission.Patients of group A were suffered from MODS complicated with pancreas injury while patients of group B had MODS without complicatios.They were compared and evaluated by acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,6-hour clearance rate of lactic acid,incidence of shock,fluid resuscitation in the first 24 and 48 hours,bladder pressure and 28-day accumulative mortality.Results APACHE Ⅱ score in group A was significantly higher than that in group B (P ＜ 0.01).Compared with group B,the 6-hour clearance rate of lactic acid was lower,the incidence of shock increased obviously,and larger volume of fluid resuscitation was needed in the first 24 and 48 hours in the group A (P ＜ 0.05).Bladder pressure,incidence of feeble bowel sounds and the mortality in the group A were higher than those in group B,but the difference had no statistical significance (P＞0.05).Conclusions MODS complicated with pancreas injury is more severe than MODS without complications thereby resulting in higher incidence of shock and the poorer response to fluid resuscitation.

Objective To explore the treatment of thromboangitis obliterans (TAO) of lower extremities.Methods From March 1994 to February 2009,24 cases (26 limbs) affected by chronic ischemia were diagnosed as TAO by Doppler ultrasound and DSA,CTA or MRA.According to the different levels of the extensive and diffuse arterial occlusion,the revascularization was performed in the ways:19 cases (21 limbs) underwent venous arterialization,3 cases (3 limbs) underwent endovascular therapy,and 2 cases (2 limbs) underwent thrombectomy.ResultsAfter the venous arterialization,19 cases (21 limbs) were followed up for 1 to 14.5 years.Apart from the 5 limbs amputation (23.8%),the postoperative results of the most limbs were satisfactory (61.9%).The ABI before therapy (0.38?0.11) was significantly lower than that 6 months after therapy (0.79?0.08),P

Objective To investigate the efficacy and the course of desensitization treatment in bronchial asthma with positive specific IgE to dust mite in children. Methods A total of 105 children with bronchial asthma with positive specific IgE to dermatophagoides farinae allergens were randomized into the observation group and the control group. Children in the control group were treated to continue anti-asthma according to the routine of prevention and treatment children with asthma. Chinldren in the observation group were treated by dermatophagoides farinae drops in addition to the treatment of children in the control group. The recurrence of asthma was compared between two groups at 25 weeks post-treatment. At 25 weeks post-treatment , children in the observation group was randomly divided into the observation groupⅠand group Ⅱ. Children in the observation groupⅠreceived continuous treatment except for desensitization treatment. Children in the observation group II received the sublingual immunotherapy with dermatophagoides farinae drops (No.4) for 1 year in addition to the treatment in the observation groupⅠ. The recurrence of asthma was also compared between the two sub-groups. Results The rate and times of recurrence of asthma were lower in the observation group than those in the control group(P < 0.05), with no significant differences between the observation groupⅠand groupⅡ (P > 0.05). Conclusion The recurrent rate and frequency of asthma could be reduced by the sublingual immunotherapy with dermatophagoides farinae drops in children with asthma of positive specific IgE to dust mite. The course of treatment may be half year long.

Objective To study the pelvic fascia related to pelvic autonomic nerve and detect the anatomical localization of pelvic autonomic nerve by marker in adult male.Methods Twelve pelvises of adult male harvested from cadavers were studied by dissection.Results Hypogastric nerve was embedded in the posterior leaf of the visceral pelvic fascia.Pelvic plexus was situated between vesicohypogastric fascia and visceral fascia.Pelvic nerve branch of seminal vesicle and prostate was located at the anterolateral part of Denonvilliers fascia.Sacral promontory,ureter,junction of Denonvilliers fascia,visceral fascia and seminal vesicle could be regarded as anatomical markers for pelvic autonomic nerve.Conclusion The anatomical characteristics of pelvic autonomic nerve can be used for protecting and isolating pelvic autonomic nerve in total mesorectal excision of adult male.

Objective To evaluate the long-term therapeutic results of intersphincteric resection (ISR) in the treatment of ultra-low rectal cancer.Methods Sixty cases of ultra-low rectal cancer with the inferior border of the tumor within 5 cm to the edge of anus underwent intersphincteric resection (ISR),and the clinical data were analyzed retrospectively.There were 39 males,21 females and their average age was 55 years old (range from 30 to 77 years old).The inferior border of the tumor were from 28 to 50 mm to the edge of anus,averaging 42 mm.Results Sixty patients underwent intersphincteric resection successfully with 3 cases developing anastomotic leakage and 2 cases anastomotic stenosis postoperatively.After a median follow-up period of 49 months (range from 18 to 90 months),local and distant recurrence were observed in 6 and 4 patients respectively.Five-year overall survival rate and disease-free survival rate were 88.3％ and 83.3％ respectively.The mean stool frequency were (3.8 ± 1.3) times in each day based on data from 53 patients,and the stool control function of 73.6％ of all patients was preserved satisfactorily according to Kirwan classification.Conclusions This study indicated that intersphincteric resection might be a candidate technique in the treatment of early stage ultra-low rectal cancer restricted within rectal wall and could achieve satisfactory long-term results in both oncologic and functional respects.

Objective To evaluate the long-term functional outcome after ileal pouch anal anastomosis with modified double-stapled technique.Methods From January 2002 to March 2011,forty-five patients underwent ileal pouch anal anastomosis with modified double-stapled technique.The clinical data of these patients were reviewed.The postoperative anal function was assessed by Kirwan classification and Oresland pouch-specific function score.Results During the median follow-up of 65 months,2 patients with malignant adenomatous polyps died,2 patients were diagnosed dysplasia by biopsy,4 patients developed mild to moderate anastomotic narrowing,1 patient developed persistent anastomotic stricture needing surgical intervention,16 patients developed at least 1 episode of pouchitis.There was no incontinence in these patients,and the median functional Oresland score was 6,3 and 2 after 1 year,2.5 years and 5 years respectively.Conclusion The functional results of ileal pouch anal anastomosis with modified double-stapled technique are promising,with no incontinence in our patients.

Objective To compare the application,safety and theraputic effect of local resection of early rectal tumours by transanal endoscopic microsurgery(TEM) and the conventional transanal excision(TAE).Methods The data of seventy-six patients who were treated by conventional transanal excision from January 2003 to July 2006 and fifty-three patients who were treated by transanal endoscopic microsurgery from September 2006 to February 2010 in Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were reviewed.Results Age,sex,tumour size,blood loss,postoperative hospital stay were similar in the two groups(P＞0.05).The median distance from the anal verge was significantly higher in the TEM group ( TEM/TAE =7.0/5.0 cm,P ＜ 0.01 ).The operation time was significantly longer in the TEM group (TEM/TAE =70.00/30.00 min,P ＜ 0.01 ).There was no operation-related mortality in both groups (P ＞ 0.05 ).Two patients in the TEM group developed postoperative haemorrhage,and one patient developed pulmonary infection and retention of urine respectively.There were two secondary haemorrhage cases in the TAE group.On median follow-up of 30 months,there was 7.8％ recurrence rate in the TEM group,compared with 23.2％ the in TAE group.Conclusions Transanal endoscopic microsurgery is a safe and effective mininally invasive surgical technique for the treatment of early rectal neoplasm.It has broader indication,and better theraputic effect than the conventional transanal excision.

Objective: To investigate the protective effect of rhubarb (大黄) combined with scopolamine on gastric and gut mucosal barrier in patients with severe trauma. Methods: Forty patients with severe trauma, injury severity score (ISS)≥25, were randomly divided into two groups (each n=20), namely common therapy group (CM group) and rhubarb (infused into stomach) combined with scopolamine group (RS group). In RS group, rhubarb combined with scopolamine were given just after the first time measuring gastrointramucosal pH (pHi), the other treatment was the same as CM group.The mean arterial pressure (MAP) and heart rate (HR) were recorded, and pHi, lactic acid, interleukin-6 (IL-6) and tumor necrosis factor-? (TNF-?) were measured on admission and at 24, 48 and 72 hours after admission. Results: The MAP, HR and pHi were uptrend in both groups. There were significant increase in MAP and pHi of RS group at 72 hours compared with those of CM group (both P

The technology of powder X-ray diffraction (XRD) was used for analysis Chloriti Lapis and the XRD Fourier fingerprints were established. The dates were analyzed by fuzzy cluster and fingerprint similarity evaluation software to compare the similarity of samples. XRD fingerprint with 10 common peaks of 14 batches of Chloriti Lapis were established. The average, median coefficients of crystal lattice spacing d (A), peak position 2 theta, relative intensity value I/I0 (%) were all more than 0.95. And similarity( angle cosine value) were all more than 0. 97. There were small number samples differed from others. And obvious differences between the pre-and post-processing samples.
