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 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.

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 establish a novel glucocorticoid (GC)-resistant human diffuse large B lymphoma(DLBCL) cell line Toledo/dexamethasone (DEX) by the exposure to DEX,and observe the biological characteristics of resistant and parental cell line,investigate the mechanisms of glucocorticoid-resistance.Methods Toledo/DEX was established by the exposure to DEX,the dose of which was increased gradually and intermittently for long periods of time.Toledo,in the logarithmic growth phage,was incubated in the culture medium containing DEX at the concentration of 1×10-8 mol/L at first.The medium without DEX was replaced after for 96 hours until the cell line re-entered the logarithmic growth phase.Repeat the above steps to acquire the ultimate concentration of DEX in the medium as 1.024 ×10-5 mol/L.The biological characteristics of resistant and parental cell lines were evaluated.Results Toledo/DEX was more invasive in the aspects of ultrastructure,tumorigenicity and drug sensitivity.Meanwhile,Toledo/DEX achieved some stable biological characteristics such as morphology,karyotypes and immunophenotype.Furthermore,GC receptor (GR) α and GR β protein expression analysis showed that GR was involved in the mechanism of the GCresistance.Conclusions Toledo/DEX is a drug-resistant cell line with a stable biology backgroud.These results may help shed light on the knowledge of GC-resistance and lay the groundwork for searching new therapeutics to reverse drug-resistance.

Currently,independent clinical medial femoral plate is more needed to apply in more complex C3 distal femoral fractures and knee valgus orthopedic surgery.The doctors always pre-bent the contralateral femoral lateral plate in order to achieve close to the natural shape of the bone.The cold deformation of the plate can change the metallographic structure and the biomechanics,and the position of the screw holes in the plate may also affect the healing of fractures.Compared with traditional manufacturing techniques,3D printing technology as a core technology in third industrial revolution,instead prior manufacture of molds,removing the large amount of material in the manufacturing process and the complex process of forging a final product,it is more suitable for difficult to machine materials,manufacture,inspection shape design,assembly,testing and fast reverse engineering.Therefore,a personalized interior distal femoral plate with 3D printing technology was designed,and the application of the plate,the current situation and prospects of 3D printing technology and other aspects were summarized in this article.
