Edema, as one of common clinical diseases, could be treated by taking medicines and adopting external therapies with traditional Chinese medicines (TCM). In recent years, there have been many clinical and basic studies concerning external therapies with TCM on edema Data showed that the external therapies are mostly composed of such purgating drugs as Rhei Radix et Rhizoma, Natrii Sulfas and Pharbitidis Semen, heat-clearing drug such as Phellodendri Chinensis Cortex and resuscitation-inducing drug such as Borneolum Syntheticum. The study showed that ingredients of external therapies did not pass through hilum and hepatic system, and thus avoided the first pass effect of livers. They enabled effective components of drugs to be rapidly absorbed through pores and skins, strengthened the effect against edema, shortened the treatment course, decreased side effects, and were convenient and inexpensive. External therapies with TCM could play unique advantages in inhibiting edema in the future clinical studies.

As a transmembrane protein, CD47 is widely distributed in a variety of cells. It can bind to signal regulatory protein alpha (SIRPα) on macrophages and release inhibitory signals, thus avoiding phagocytosis of macrophages. In lymphoma cells, the expression of up-regulation of CD47 expression in lymphoma cells is one of the important mechanisms for inducing immune escape, and it is also a potential therapeutic target. This article reviews the research progress of CD47-induced immune escape, monoclonal antibodies targeting CD47 and cellular immunotherapy in the treatment of lymphoma.

Objective To investigate the expression and significance of transforming growth factor-beta1(TGF-? 1),transforming growth factor-beta receptor typeⅠ(TGF-? RⅠ) in human ovarian carcinoma. Methods Inmmunohistochemical SP method was used to detect the expression of TGF-? 1 and TGF-? RI in 85 cases of benign and malignant ovarian tumors. Results The positive rate of TGF-? 1 in benign and malignant ovarian tumors was significantly higher than that in the normal ovarian tissues(P

Objective To assess the possibility of using arterial pressure waveform or pulse oximetry plethysmographic waveform variation to estimate the pulmonary arterial wedge pressure (PAWP) Methods Fourteen ASA Ⅰ Ⅱ patients aged 33 69 years and weighing (62 0?9 5)kg scheduled for elective abdominal tumor surgery were studied Their Hb exceeded 120g/L and Hct 35% Anesthesia was induced with midazolam 0 04mg/kg atropine 8?g/kg,fentanyl 2?g/kg,propofol 2mg/kg and vecuronium 0 1mg/kg and maintained with isoflurane The patients were intubated and mechanically ventilated and P ET CO 2 was maintained at 4 67 5 33 kPa Radial artery was connulated for arterial pressure waveform monitoring and Swan Ganz catheter was inserted via right internal jugular vein and connected to continuous cardiac output monitor (VGS2,Baxter,USA) for hemodynamic monitoring Hypervolumic hemodilution was performed after induction of anesthesia and intubation with crystalloid and colloid (1:1) infused at a rate of 0 7ml?kg -1 ?min -1 PAWP, systolic pressure variation (SPV), delta down (dDown), SPV plet and dDown plet and other hemodynamic parameters were measured and recorded when total fluid volume (crystalloid and colloid) infused reached 10ml/kg and 20 ml/kg and at the end of operation, CVP was maintained at 10 12mm/kg during operation Systolic blood pressure at the end of Valsalva maneuver (airway pressure was kept at 30 cmH 2O) and the systolic pressure before the Valsalva maneuver during apnea were used to calculate arterial pressure ratio (APR) Results APR,SPV,dDown,SPV plet and dDown plet all correlated well with PAWP (r=o 7174,-0 6951,-0 680-0 5216 and 0 6237 respectively P

Objective To detect the effect and mechanism of Cyr61 on the apoptosis of renal tissue caused by early stage of ischemic acute kidney injury (AKI). Methods 30 SD rats were randomized into 5 groups, including control group, AKI group, AKI+bicarbonate group, AKI+blank virus group, and AKI+over?expression Cyr61 virus group. After animal models were created for 2h, serum and renal tissue were collected from sacrificed animals. Expression level of TNF?α was determined by ELISA. HE staining was used to observe the histologic changes of renal tissues. The levels of NF?κB p65 and TNFR1 were measured by immunohistochemical method. RT?PCR and Western blotting assay were adopted to detect the mRNA and protein expression levels of NF?κB p65, TNFR1 and Caspase3. Results Compared with control group, AKI group, AKI+bicarbonate group, AKI+blank virus group, AKI+over?expression Cyr61 virus group had obvious kidney injury. The levels of TNF?α, the mRNA and protein expression levels of NF?κB p65, TNFR1 and caspase3 were markedly up?regulated. Over?expression of Cyr61 significantly attenuated the degree of pathological injury, numbers of apoptotic renal tubular epithelial cells and increased the degree of Scr. Although compared with other groups, the level of TNF?α in kidney tissue had no difference, there was obvious decreased protein level of NF?κB p65, while the increase of TNFR1 and Caspase3 protein was moderate. Conclusions During the early stage of AKI, over expression of Cyr61 could inhibit apoptosis, which may be related to the suppression of TNFR1 transcriptional expression and interference of TNF?αpathway. Its underlying mechanism therefore deserves further research.

The HPLC-UV-Fluorescence technique and HPLC-UV-MS technique were used to determine fluorescence molecule in gastric juice of patients with malignant gastric cancer,which is identified as tryptophan. Lidocaine was detected in gastric juice of patients who were examined by gastric endoscopy. A method was developed to determine concentration of tryptophan and lidocaine in gastric juice using HPLC-UV technique,in which Kromasil C_(18) column(150 mm×4.6 mm,5μm) and methanol(containing 0.1% trifluoroacetic acid (TFA))-water(containing 0. 1% TFA) as gradient mobile phase were used. The linear relationships were obtained between the concentration of tryptophan in the range of 0.5 - 200 mg/L and its peak area at 278 run with correlation coefficient of 0.9994,and between the concentration of lidocaine in the range of 20 -5000 mg/L and its peak area at 254 nm with correlation coefficient of 0.9992. The limit of detection is 0.15 mg/L for tryptophan and 5 mg/L for lidocaine. The recovery is 70. 8% - 110. 4% for tryptophan and 87. 1% -116.2% for lidocaine. 38 gastric juice samples of patients with malignant gastric disease and 48 gastric juice samples of patients with benign gastric disease were tested and the concentration of tryptophan in those two groups of gastric juice samples was apparently different.

OBJECTIVETo analyze the clinical characteristics of elderly patients with spinal tuberculosis and explore its clinical effects with anti-TB drugs alone.

METHODSFrom January 2008 to July 2010, the data of 36 patients with spinal tuberculosis underwent conservative treatment of anti-TB drugs alone were analyzed. There were 19 males and 17 females with an average age of 73.5 years (ranged, 60 to 85). All patients were in the active phase with high ESR and CRP levels and were treated with 3HRZE/6-9HRE (course from 9 to 12 months). According to clinical symptoms, chemical examination, radiological image to adjust drug and depending on VAS score to evaluate pain.

RESULTSAll the patients were followed up from 8 to 24 months with an average of 15 months. Tuberculose of 31 patients healed after chemotherapy from 9 to 12 months and ESR and CRP recovered normally. Levofloxacin and para-amino salicylic acid were used in 4 cases because of 4 cases occurred drug fast for RFP or INH, after 15 months, their obtained healing. Symptom of 1 case got worse during chemotherapy, and surgical treatment were performed, after 3 months, ESR and CRP recovered normally, X-ray and CT showed spinal osteosclerosis and fusion without significant kyphosis and internal fixation loosening. Cobb angle was respectively(17.6+/-2.3) degrees, (18.1+/-2.7) degrees before treatment and last follow-up (P>0.05). MRI showed abscess was absorbed and spinal inflammation subsidised. VAS score was respectively 6.5+/-1.7, 1.4+/-0.5 before treatment and last follow-up (P<0.05). Seven patients had complications relating with drug adverse reaction,after discontinuation and treated with clinical symptom,the patients recovered normally.

CONCLUSIONAnti-TB drugs alone can obtain satisfactory effects in treating early senile spinal tuberculosis, but strict supervision and individual administration should not be disregardful.

Objective To evaluate the performance of a DNA microarray method for detecting HBV antiviral drug-resistant mutations. Methods Two hundred and twenty four serum samples from patients with CHB were tested in parallel by DNA microarray and direct sequencing for the mutations within the HBV reverse transcriptase (rt) region, which included rtL180, rtA181, rtM204 and rtN236. Samples with discrepant results were retested by clonal sequencing. Results Complete concordance between DNA microarray and direct sequencing results was observed in 214 out of 224 samples (95. 5% ). The presence of mixed viral populations in the other 10 samples detected by DNA microarray but not by direct sequencing was confirmed by clonal analysis. The DNA microarray could detect minor viral populations which constituted 5.0%-15. 0% of the total viral load. Conclusion DNA microarray is highly consistent with direct sequencing in detecting HBV mutations conferring drug resistance and more sensitive in detecting mixed mutant and wild-type sequences than direct sequencing, which makes it a useful tool for early detection of drug resistance early.

Objective To investigate the effect of ultrasound-guided transverses abdominis plane (TAP)block on the efficacy of postoperative analgesia in patients undergoing abdominal hysterectomy. Methods Sixty ASA Ⅰ - Ⅱ patients scheduled for abdominal hysterectomy under general anesthesia were randomly divided into 2groups (n = 30 each): ropivacaine group (group R) and normal saline (group NS). After induction of anesthesia,ultrasound-guided bilateral TAP block was performed, and 0.375% ropivacaine 40 ml was injected in group R,while the equal volume of normal saline was used instead in group NS. The patients received patient-controlled intravenous analgesia (PCIA) with sufentanil after operation. The VAS score was maintained ≤ 3, the level of sedation was evaluated with Ramsay sedation score, and the comfort level was evaluated with Bruggrmann comfort scale (BCS) score at 2, 6, 8, 12 and 24 h after operation. The hemodynamic parameters were recorded. The consumption of sufentanil during operation and within 24 h after operation, the number of successfully delivered doses ( D1 )and the number of attempts ( D2 ) within 24 h after operation were recorded. D1/D2 was calculated. The adverse reactions were also recorded. Results SP, DP, HR, SpO2 and RR were in the normal range and there was no significant differences between the two groups ( P ＞ 0.05). The consumption of sufentanil were significantly lower,while the BCS score and D1/D2 higher in group R than in group NS (P ＜ 0.05). There were no adverse reactions in both groups. Conclusion Ultrasound-guided TAP block reduces the perioperative sufentanil consumption and enhances the efficacy of postoperative analgesia in patients undergoing abdominal hysterectomy.

Objective To explore the role of microRNA-206 (miR-206) in peripheral blood mononuclear cells (PBMCs) in infantile bronchiolitis caused by respiratory syncytial virus (RSV).Methods Thirty-five cases of infantile bronchiolitis and 25 cases of healthy controls were enrolled into the current study.PBMCs were isolated from the peripheral blood of both healthy subjects and those with infantile bronchiolitis in the acute and the convalescent stages.Total RNAs were extracted from PBMCs which were stimulated by phorbol-12-myristate-13-acetate (PMA) and Ionomycin, and then the RNA was transcribed reversely into cDNA.The expressions of miR-206 and Kruppel-like transcription factor 4 (KLF4) were detected by real-time quantitative polymerase chain reaction (qRT-PCR) method.Plasma interleukin-17 (IL-17) was determined by enzyme linked immunosorbent assay (ELISA).Results There was a significant difference in miR-206 levels of children with RSV bronchiolitis in the acute stage(0.055 ±0.018) and the convalescent stage(0.187 ±0.069) as well as the healthy controls(0.204 ± 0.075).Through pairwise comparison, the miR-206 levels in the children in the acute stage were significantly lower than those in the convalescent stage and healthy control group (P ＜ 0.01), but no statistical significance was found between the convalescent stage group and healthy control group(P ＞ 0.05).The levels of KLF4 mRNA of children in the acute stage,convalescent stage as well as the healthy subjects were 0.588 ± 0.161,0.086±0.024,0.075 ±0.019, respectively,which was significantly difference (P ＜ 0.01).The levels of IL-17 were (58.26 ±25.88) ng/L, (9.87 ± 3.01) ng/L, (7.65 ± 2.16) ng/L, respectively (P ＜ 0.01).Compared to the convalescent and the normal control group,both the KLF4 mRNA and IL-17 levels were markedly higher in the acute stage (P ＜ 0.01), but there were no significant differences between children with RSV bronchiolitis in convalescent stage and in the healthy controls (P ＞ 0.05).Furthermore, the result of this study showed a negative correlation between the expression of miR-206 and KLF4(r =-0.624 ,P ＜0.01)and IL-17 (r =-0.609 ,P ＜0.01) in children in the acute stage and a positive correlation between KLF4 mRNA and IL-17 in children in the acute stage (r =0.662, P ＜ 0.01).Conclusion The levels of miR-206 may play a role in the onset of RSV associated post-bronchiolitis (PB) and the low expression of miR-206 in children infected with RSV may increase the susceptibility to PB.
