OBJECTIVETo explore the impact on neutrophil-to-lymphocyte ratio (NLR) and the quality of life (QOL) in the patients of non-small-cell lung cancer (NSCLC) treated with wheat-size moxibustion therapy.

METHODSSeventy patients of NSCLC were randomized into an observation group and a control group, 35 cases in each one. Finally, 33 cases were participated in the observation group and 32 cases in the control group for statistical analysis. In the observation group, Zusanli (ST 36) and Feishu (BL 13) were selected for grain-size moxibustion, 9 moxa cones on each acupoint, once a day. There was the follow-up visit without any treatment applied in the control group. The trial lasted for 6 weeks. The changes in NLR and the QOL score before and after treatment were observed in the patients of the two groups and the differences were compared between the two groups.

RESULTSCompared with the condition before treatment, in the observation group, NLR was reduced apparently (P< 0.05), the general health state/life quality field, physical functioning, emotional functioning, cognitive functioning, fatigue, pain, short breath, insomnia and anorexia were improved apparently (all P < 0.05). In the control group, the differences were not significant in NLR, the general health states/life quality field, physical functioning, emotional functioning, cognitive functioning, role functioning, social functioning, fatigue, pain, short breath, insomnia and anorexia before and after treatment (all P > 0.05). In comparison of the two groups, NLR was reduced apparently in the observation group as compared with that in the control group after treatment (P < 0.05). The scores of the general health state/life quality field, physical functioning, emotional functioning and cognitive functioning were increased apparently as compared with those in the control group after treatment (all P < 0.05). The scores of fatigue, pain, short breath, insomnia and anorexia in the observation group were reduced apparently as compared with those in the control group after treatment (all P < 0.05).

CONCLUSIONThe wheat-size moxibustion therapy reduces NLR and improves the immune function and quality of life in the patients of NSCLC.

Shape memory polymer (SMP) is a new type of functional materials.SMP has lots of advantages such as low density,light weight,high shape-recovery rate and low cost,but its stiffness is low and shape recovery force is small.Therefore,the reinforced SMP composite has become a hot research focus.The latest progress of reinforced SMP composite is reviewed,with the emphasis placed on the analysis of the influence of reinforced materials on SMP properties including short fibers,particles and the mixture of fibers and particles.Finally,problems exist in the study and the prospect of reinforced SMP composite are discussed briefly.

Objective To investigate the clinical features of primary retroperitoneal fibrosis (RPF), and to find out better method for diagnosis and therapy. Methods Nine patients with primary RPF in Peking Union Medical College Hospital since 1990 to 2003 were analyzed retrospectively. Results All patients had abnormal findings in CT or MRI, and 8 of them had chronic non-specific inflammation of the retroperitoneum in pathology. Six patients had renal involvement and 2 of them had severe renal failure. Eight of the patients had received therapy with corticosteroid or tamoxifene. Conclusions RPF is an uncommon collagen vascular disease characterized by a chronic non-specific inflammation of the retroperitoneum.Because of the atypical manifestations of RPF, awareness of the disease is important.CT and (or) open biopsy remains the gold standard for diagnosis.Management typically includes surgery and drug treatment.Corticosteroid therapy or more recently,tamoxifen has been used successfully. The clinical and radiographic improvement with drug treatment has been seen in several patients and confirmed the diagnosis,thereby early diagnosis and treatment can bring the patient more excellent renal and general outcome.

BACKGROUND: RT-Q medical biomembrane, the novel copolymer synthesized from lactic acid and hyaluronic acid, not only possesses the advantages of hyaluronic acid, such as multiple biological functions, excellent flexibility and biocompatibility, but also has the merits of polylactic acid fragments to be easily processed and transformed to membrane when encountering water. OBJECTIVE: To investigate the hemostatic effect of RT-Q medical biomembrane in rat external jugular vein hemorrhage model, and to evaluate its histocompatibility by locally applying it to rat muscle. DESIGN: Randomized controlled animal trial.SETTING: Department of Pharmacology, Department of Pharmacognosy, West China School of Pharmacy, Sichuan University.MATERIALS: 130 male Wistar rats aged 6 weeks, weighing 170-210 g, were selected. Eighty rats were used for evaluation of hemostatic effect, and the other fifty were used in biocompatibility experiment. Animal intervention met the animal ethical standard. RT-Q aerosol composed of DL-lactic acid and hyaluronic acid, α-cyanoacrylate, acetone (solvent), freon (propellant) and excipient aerosol composed of acetone and freon (propellant) (Batch number 20050311) were provided by Department of Pharmaceutics, West China School of Pharmacy, Sichuan University.α-cyanoacrylate medical adhesive(SUNCON medical adhesive) (Batch number 20050930) was produced by Beijing Suncon Medical Adhesive Science and Technology Development Co., Ltd. METHODS: Haemostatic effect: Eighty male rats were randomly divided into four groups, served as RT-Q, SUNCON (positive control), excipient group and non-treatment group (negative control), twenty in each group. After anesthesia was induced, external jugular vein of rats was exposed, and an approximately 0.6 cm incision was made to create hemorrhage. The bleeding areas were blotted by antiseptic gauze. After removing the gauze, the bleeding surfaces were immediately treated with RT-Q aerosol in the RT-Q group, excipient aerosol in the excipient group, 0.15 mL SUNCON medical adhesive in the SUNCON group, or no agent in non-treatment group, respectively. Then, injury surfaces were covered by gauze. In the non-treatment group, bleeding was left to naturally stop. Bleeding time and blood loss (gauze weight after hemostasia - that before hemostasia) were determined. Local histocompatibility: Rats were divided into A and B groups. Incision was made in rat post-leg muscle after anesthesia was induced. Left bleeding surfaces were treated with excipient aerosol, and right bleeding surfaces were treated with RT-Q aerosol in group A (n=30). The same incision as the group A was made, but no intervention was performed in the group B (n=20). Tissues were possessed and HE-stained for pathological observation under light microscope at days 1, 2, 3, 4, 5, 6, 7, 15, 23, 30 after the surgery. Effect of biomembrane on wound healing, degradation and toxicity to tissues surrounding injuries were observed. MAIN OUTCOME MEASURES: Bleeding time and blood loss in hemostatic experiment; wound healing, biodegradation and toxicity to tissues surrounding injuries in local histocompatibility experiment. RESULTS: 130 rats were involved in the result analysis. Histopathologic examination showed RT-Q membrane had no effect of promoting or delaying wound healing. Membrane formed by RT-Q aerosol began to degrade on the 15th day, absorbed completely during 3-4 weeks, and had no toxicity to surrounding tissues. Bleeding time and blood loss were reduced in the RT-Q group than in the non-treatment group and the excipient group (P < 0.01). There was no significant difference between the RT-Q group and the SUNCON group (P > 0.05).CONCLUSION: RT-Q medical biomembrane as α-cyanoacrylate medical adhesive has significant hemostatic effects on topical bleeding, and possesses good histocompatibility.

Objective To establish a three-dimensional (3D) model of the diaphragm type of Budd-Chiari syndrome (BCS) with perforated membrane,to analyze changes of hemodynamic parameters pre and post percutaneous transluminal angioplasty (PTA) and to analyze any possibly related mechanical factors for postoperative recurrence in BCS.Methods The data on enhanced MRI from patients suffering from BCS with perforated diaphragm of inferior vena cava were reconstructed into a 3D model Computational fluid dynamics (CFD) were applied for numerical simulation based on the model,and the results were expressed as cloud images.Results The total number of model units of the finite element model for preoperative inferior vena cava stenosis was 16 422,and the total number of nodes was 48 170.The total number of model units for postoperative inferior vena cava was 16 539,and the total number of nodes was 51 339.Hemodynamic patterns of the lesion areas were effectively reflected in the 3D flow dynamic model for BCS.By comparing the hemodynamic parameters before and after interventional therapy,the data indicated that there was a gradual decline in wall pressure from the telecentric side.The largest blood flow velocity as well as wall shear stress were observed in the stenotic area of inferior vena cava.Both a large postoperative vascular central velocity and a low increase in local pressure predicted occurrence of vascular restenosis.Conclusions The establishment of a 3D fluid model of inferior vena cava revealed that there were mechanical changes in the location of the lesion.Variations in blood flow patterns exert a far-reaching influence on distribution of hemodynamic parameters,including local blood flow velocity,vascular wall pressure and shear stress.All these might be related to recurrence of BCS after interventional therapy.

Objective To explore the clinical application of 3D-printing model in guiding interventional management of Budd-Chiari syndrome (BCS) and in teaching practice.Methods A patient with typical BCS of inferior vena cava type was selected.By using MR enhanced scanning,the original MRA data of DICOM format were extracted,and then the digital data were extracted and reconstructed to obtain 3D BCS model by Simpleware software.The 3D BCS entity model,using 1 ∶ 1 ratio,was printed out by a 3D printer.An experienced chief physician made a simulated interventional manipulation on this 3D BCS entity model.Results The BCS 3D model was successfully printed.Simulated operation could be easily performed on the 3D-printing model,in this way the chief physician could make a demonstration of interventional procedure of BCS to the junior doctors and medical students.Interventional therapeutic manipulation for BCS could be well demonstrated on the 3D-printing model of BCS,which was very helpful in guiding teaching practice and in promoting the communication between doctors and patients.Conclusion The BCS 3D-printing model can truly reflect the spatial architecture features of the inferior vena cava and the hepatic veins,which are very valuable for the making of surgical plan,for the demonstration of simulation operation,and for teaching practice.Moreover,3D-printing model can stereoscopically display the location and morphology of the lesion,which can improve patient's understanding of the disease,thus,the communication between doctors and patients can be strengthened.

Objective:To investigate the changes of advanced glycosylation end product(AGEs)/sodium-glucose cotransporter-1(SGLT-1) in intestinal and renal tissues and intestinal flora of mice with diabetes kidney disease.Methods:Twenty KKay mice were divided into diabetic group(DM group, n=10) and diabetic kidney disease group(DKD group, n=10). The concentrations of serum AGEs, lipopolysaccharide(LPS), tumor necrosis factor-α(TNF-α), and intereukin-6(IL-6) were measured. Western blot technique was used to detect the protein expression of AGEs and SGLT-1 in kidney and intestinal tissue, and high-throughput sequencing was used to analyze the difference of intestinal flora. Results:The levels of inflammatory markers TNF-α, IL-6, and serum endotoxin in DKD group were significantly higher than those in DM group( P<0.05). The contents of AGEs in serum and intestine and kidney were increased, and the contents of SGLT-1 in intestine and kidney were increased( P<0.05). Metastats test showed that the abundance of Verrucomicrobia decreased and the abundance of Proteobacteria increased in DKD group( P<0.05). G - bacteria such as Aeromonas, Enterobacter, Morgan, Klebsiella, Serratia, and Burkholderia were relatively dominant, and the abundance of Akkermansia was significantly lower than that in DM group( P<0.05). Conclusion:The increase of AGEs in intestinal tract of DKD mice may induce intestinal dysbacteriosis, especially the increase of Proteobacteria, the decrease of Verrucosa and Wilhelm Ackermann, and the leakage of G-bacteria into the blood to produce intestinal endotoxemia and cause inflammatory reaction, this may be an important factor in the development of DKD. SGLT-1 is elevated in intestinal tissue, which may be involved in the development of DKD.
