Objective To discuss the value of Visfatin in severity evaluation in patients with severe pneumonia via observation on the variations of the plasma level of Visfatin. Method Seventy subjects including 40 patients with severe pneumonia ( group A) and 30 patients with non-severe pneumonia (group B) admitted to the ICU of emergency department and general wards from June 2009 to June 2010, were enrolled in this prospective study, and another 30 healthy individuals from physical examinees were included as subjects in control group (group C). Patients with severe diseases of heart, brain and kidney, cancers, autoimmune disease, or under special treatment in latest one month were excluded. For the subjects of all three groups, the plasma levels of Visfatin, IL-6, IL-8 and TNF-α were measured by using ELISA, while the level of CRP was assayed by using immunoturbidimetry, and the routine blood test was performed as well. The blood gas analysis and Acute Physiology and Chronic Health Evaluation Ⅱ ( APACHE Ⅱ) were carried out in patients with pneumonia. Comparisons between groups were made by t-tests, ANOVA or nonparametric test. Correlation analysis was carried out by Pearson correlation coefficient or Spearman rank correlation test. Results The plasma level of Visfatin in patients with severe pneumonia (group A) was significantly higher than that in patients with non-severe pneumonia (group B) and in the control subjects (group C) (P < 0. 01) , and the level of Visfatin in pneumonia ( group B) and in control group (group C) , and that in group B was significantly higher than that in the controls (group C) (P <0. 01). In group A, the plasma level of Visfatin was positively correlated with CRP, TNF-α, APACHE Ⅱ and PMN% (rha =0. 653, r = 0.554, r = 0.558, r= 0.484, P <0. 05), while negatively correlated with PaO2 and PaO2/FiO2 ( rha = -0.422, r= -0.543, P <0. 05). Conclusions Visfatin may be involved in the systemic inflammation response in severe pneumonia as a pro-inflammatory cytokine which is valuable in assessing the severity of pneumonia.

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance. The RP-HPLC method was used to determine the content of mulberroside A with mobile phase of methanol-water (25: 75) at a wave-length of 326 nm. The mulberroside A was in good linear with a regression equation of Y = 46.965X (r = 0.999 6) in the range of 4.6 - 228 mg x L(-1). In 14 batches of samples, the mulberroside A in 4 batches of them was less than 0.5 g x L(-1), and was more than 2.0 g x L(-1) in the other batches. It was suggested that the content limit of mulberroside A should be no less than 1.5 g x L(-1). The HPLC fingerprints were evaluated by the similarities. It has found that the similarities of different mori liquid extracts were very low and the chemical diversity of mori cortex was the major factor of similarity. Moreover, the process impact was minimal. Thus the fingerprint was not included in this quality standard.

OBJECTIVETo explore the underwater decompression schedule for 100 m Trimix conventional diving operations and evaluate its safety through a simulated rabbits Trimix conventional diving.
METHODSAccording to the Haldane theory, the assumed time units, the classification of tissue compartments, the nitrogen super-saturation safety coefficient and the selection of methods used for the calculation of the simulated 100 m Trimix conventional diving schedule were properly selected, and the calculating method for the dive decompression schedule was thus firmly established. In our experiments, five tissue compartments were selected during the calculation of decompression schedule: 5 min, 10 min, 20 min, 40 min and 75 min, and the nitrogen super-saturation safety coefficient was calculated by 1.6. Eight New Zealand rabbits were performed a simulated 100 m Trimix dive program which was established according to the Haldane theory, and eight rabbits for intact group. The tissues wet/dry ratio and ethology were detected and observed before and after the simulated diving to evaluate the safety of decompression schedule.
RESULTSBy using the developed underwater decompression schedule, abnormal ethology changes in rabbits could not be observed after compression and decompression to the surface; and the tissues wet/dry ratio of simulated diving rabbits had no significant changes compared with the intact group (P > 0.05).
CONCLUSIONThe decompression schedule calculated by Haldane theory seemed to be safe and reliable, the diving breathing gas concentration did not cause oxygen toxicity and nitrogen narcosis among the dive rabbits, and dive efficiency was greatly improved by using enriched oxygen gas in UPTD safety range during decompression.

BACKGROUND: As a cytokine highly expressed in internal organs, visfatin could be used as a biomarker of systemic inflammation response for chronic obstructive pulmonary diseases, but few studies have reported the use of visfatin in severe pneumonia. The present study was undertaken to determine the plasma levels of visfatin in patients with severe pneumonia. METHODS: A total of 70 patients, including 40 patients with severe pneumonia (group A) and 30 patients with non severe pneumonia (group B) who had been admitted to the ICU from June 2009 to June 2010, were enrolled in this prospective study. And another 30 healthy physical examinees served as healthy controls (group C). Patients were excluded if they suffered from severe diseases of the heart, brain and kidney, cancers, autoimmune diseases, or received special treatment in the latest month. The plasma levels of visfatin, IL-6, IL-8 and TNF-α were measured by ELISA, while the level of CRP was determined by immuneturbidimetry, and the routine blood test was performed. Blood gas analysis and Acute Physiology and Chronic Health Evaluation II (APACHE II) were performed in patients with pneumonia. Comparisons between the groups were conducted by Student's t test, ANOVA or nonparametric test. Correlation analysis was carried out by Pearson's correlation test or Spearman's rank-order correlation test. RESULTS: The plasma level of visfatin in group A was significantly higher than that in groups B and C (P<0.001), and the level of visfatin in group B was significantly higher than that in group C (P<0.001). The plasma level of visfatin was positively correlated with CRP, TNF-α, APACHE II and PMN% in patients with severe pneumonia (rho=0.653, r=0.554, r=0.558, r=0.484, respectively, P<0.05 for all), while it was negatively correlated with PaO2 and PaO2/FiO2 (rho=?0.422, r=?0.543, respectively, P<0.05 for all). CONCLUSION: Visfatin may be involved in the systematic inflammation response in patients with severe pneumonia as a pro-inflammatory cytokine, and it is valuable in assessing the severity of pneumonia..

OBJECTIVETo describe the clinicopathologic features and immunophenotypes of carcinoid tumorlets in the lung with bronchiectasis, and to study the morphogenesis of these tiny tumors.
METHODSThe histopathologic characteristics of 3 bronchiectasis cases with carcinoid tumorlets, 11 bronchiectasis and 2 normal lungs were studied. Specific markers of the tiny tumors and the number of neuroendocrine cells (NECs) in the airway mucosa were immunohistochemically detected by EnVision method.
RESULTSThe tumorlets in the lungs presented as multi-focal nodules and most were displayed only under microscopy. These cells were arranged in clusters and foci of fascicles which were situated in the surrounding bronchial wall and bronchioles adjacent to bronchiectatic lesion, or in the scar tissues. The tiny tumors were consisted of short fusiform cells and small ovoid cells. Their nuclei were circular, oval or long fusiform and the cells were strongly argyrophilic on Grimelius staining. Intensive positive immunostaining for calcitonin, chromogranin A, NSE and gastrin were detected. Weak positive for CK, EMA, S-100 and focal positive for HC, ACTH, 5-HT were also observed. Proliferative NECs in airway mucosa adjacent to the tiny tumors increased significantly in number, compared with those in the airway mucosa of bronchiectasis without tumorlets and normal lungs (P < 0.001, respectively).
CONCLUSIONSThe clinicopathologic features and immunophenotypes of carcinoid tumorlets resemble carcinoid tumors. They are the early stage of carcinoid development. Their development may be related to the chronic pulmonary damage resulting in hypoxia and stimulating the proliferation of NECs. These pulmonary carcinoid tumorlets can be used as a model to study the tumorigenesis of carcinoid carcinoma of the lung.

OBJECTIVETo investigate the technique and therapeutic effect of laparoscopy-insisted vaginoplasty with peritoneum in patients with androgen insensitivity syndrome.
METHODSFrom May. in the Fifth People' s Hospital of Shenzhen. The therapeutic effect was retrospectively analyzed.
RESULTSLaparoscopy-insisted vaginoplasty was successfully completely with peritoneum in patients with androgen in 4 cases. Ileumtivity segyndroment was used instead of peritoneum in one case. Open operation was not adopted in any cases. The ectopic testicles were removed during operation in 4 cases. The average operation time and bleeding volume was 60 min and 20 ml, respectively. Rectum, bladder and urethra were not injured in any case. The average vaginal length was 9 cm (range 8-10 cm) 21-28 days after operation. 6 months after operation, the surface of reconstructed vagina was smooth, ruddy and flexible, with satisfactory anatomical and functional results. Normal sexual activity was achieved in 2 cases.
CONCLUSIONSLaparoscopy-insisted vaginoplasty with peritoneum could be used for female patients with androgen insensitivity syndrome. The ectopic testicles should be removed. Estrogen supplement and psychological guide after operation are also important.
