Objective:To observe the effect of warm-unblocking acupuncture plus fluticasone propionate nasal spray on the pulmonary ventilation, level of interferon-γ (IFN-γ) and sleep quality in patients with allergic rhinitis (AR). Methods: A total of 112 AR patients were enrolled between January 2013 and August 2018 and were divided into an observation group and a control group by the random number table method, with 56 cases in each group. Patients in the observation group received warm-unblocking acupuncture plus fluticasone propionate nasal spray, and patients in the control group only received fluticasone propionate nasal spray. The nasal symptom score, pulmonary function indexes, the levels of IFN-γ and interleukin (IL)-4 in serum, and sleep quality in the two groups were compared. Results: After treatment, the total effective rate in the observation group was higher than that in the control group (P＜0.05). The nasal symptom score dropped in both groups after treatment (both P＜0.05), and the score in the observation group was lower than that in the control group (P＜0.05). The pulmonary ventilation indexes all increased significantly after treatment in the observation group (all P＜0.05); the forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio (FEV1/FVC) and the forced expiratory flow at 50%, 75% and 25%-75% of the vital capacity (FEF50%, FEF75%, FEF25%-75%) increased after treatment in the control group (all P＜0.05); the pulmonary ventilation indexes were higher in the observation group than those in the control group (all P＜0.05). The level of IFN-γ increased significantly after treatment in the two groups (both P＜0.05) and the level of IL-4 dropped significantly (both P＜0.05); the observation group had a higher IFN-γ level (P＜0.05) and a lower IL-4 level (P＜0.05) compared with the control group. Regarding the Pittsburgh sleep quality index (PSQI), the scores of subjective sleep quality, habitual sleep efficiency and sleep disturbances and the general PSQI score decreased significantly after treatment in both groups (all P＜0.05), and the scores in the observation group were significantly lower than those in the control group (all P＜0.05). Conclusion: Warm-unblocking acupuncture plus fluticasone propionate nasal spray can effectively control the clinical symptoms and improve pulmonary function in the treatment of AR; this approach can regulate the levels of IFN-γ and IL-4 towards the normal range in AR patients; it can also improve patient’s sleep quality. This method can produce more significant efficacy than fluticasone propionate nasal spray used alone.

OBJECTIVETo provide a theoretical basis for designing of lumbar intervertebral disc prosthesis by collecting the data of the lumbar endplate morphology.

METHODSA total of 100 healthy adults were measured about the following parameters: lumbar lordosis, the Cobb angle of each segment, the concavity depth (ECD) of the endplate, the location of concavity apex (ECA) of the endplate. And a correlation analysis on lumbar lordosis and ECD, ECA was made, respectively.

RESULTSIn total, 100 volunteers were measured. The mean age of the volunteer was 40 years (range 20 - 50 years); the average depth of ECD was (2. 37 ± 1. 42) mm, the average location of ECA was (52. 21 ± 9. 70) %; the average depth of ECD of inferior endplate (IEP) was (2. 81 ± 1. 52) mm (0. 54 - 7. 60 mm), and the parameter of the superior endplate (SEP) was (1. 94 ± 1. 16)mm(0. 39 - 6. 10 mm). The average depth of ECD of the IEP was bigger than of the SEP for each lumbar vertebral body. Most of the location of ECA was at the back of the intervertebral body, the average location of ECA of IEP was (49. 60 ± 8. 78) % (22. 57% - 75. 58%), and the parameter of the SEP was (55. 03 ± 9. 90) % (16. 03% -75. 58%); the mean angle of lumbar lordosis was 39. 760 11. 25°(13. 8° - 72. 00°). There was no obvious correlation between the lumbar lordosis and the ECD (r -0. 193, P =0. 195), neither was the location of ECA(r =0. 080, P =0. 592).

CONCLUSIONMost of the location of ECA is at the back of the intervertebral body, the average depth of ECD is 2. 37 mm, the average location of ECA is 52. 21%.

The properties of polyethyleneimine-cholesterol cationic lipopolymer (PEI-Chol) as gene carries and its gene transfer efficiency in vitro with lipid microbubbles were presented in this paper. PEI-Chol lipopolymer was synthesized by linking cholesterol chloroformate to the amino groups of branched poly(ethyleneimine) (PEI) of 1 800. The structure and molecular weight of PEI-Chol were confirmed by IR, 1H NMR and MADI-TOF-MS (matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry), respectively. The average molecular weight of PEI-Chol was approximately 2 000. The gene delivery system of bubble/PEI-Chol/DNA was constructed by mixed PEI-Chol/pDNA (N/P 10:1) complexes with lipid microbubbles (2-8 microm) which were prepared by DPPC, DSPE-PEG2000 and perfluoropropane with the reverse phase evaporation technique. pEGFP-Cl (enhanced green fluorescent protein) was used as report gene to investigate the DNA condensing ability of PEI-Chol lipopolymer by agarose gel electrophoresis. And their cytotoxicity and in vitro transfer efficiency of different complexes were compared with each other in A549 and MCF-7. The results indicated PEI-Chol lipopolymer can condense plasmid DNA when N/P ratio upto 4, PEI-Chol complexes and bubble/PEI-Chol/DNA complexes were nontoxic to A549 and MCF-7 when formulated at the N/P ratio of 10/1 as determined by MTT assay. This bubble/PEI-Chol/DNA delivery system provided good transfer efficiency with other desirable characteristics such as against-precipitation of plasma proteins. In conclusion, bubble/PEI-Chol/DNA complex is a novel non-viral gene delivery system.

The aim of this study was to explore the characteristics of Toll-like receptor expression in mesenchymal stem cells derived from bone marrow of healthy donor (BM-MSCs). BM-MSCs were isolated from bone marrow of healthy donor by Ficoll method. Expressions of CD34, CD45, HLA-DR, CD44 and CD71 in BM-MSCs were detected by flow cytometry. CD71 in BM-MSCs was assayed by immunocytochemistry. The adipocyte and osteoblast induction of BM-MSCs were detected by alizarin red stain and oil red stain respectively. TLR 1 - 10 mRNA levels in BM-MSCs were evaluated by semiquantitative RT-PCR. The results showed that expressions of CD34, CD45 and HLA-DR in BM-MSC were negative while the expressions of CD44 and CD71 were positive. CD71 in BM-MSCs was positive. After induced by osteoblast and adipocyte inductor, BM-MSCs were positive for alizarin red staining and oil red staining respectively. All of TLR 1 - 10 mRNA were found in BM-MSCs with high expression levels of TLR2, TLR3, TLR4, TLR7, TLR8, TLR9 and low expression levels of TLR1, TLR5, TLR6, TLR10. In conclusion, different levels of TLR 1 - 10 mRNA were expressed in BM-MSCs of healthy donor.

OBJECTIVETo investigate the clinical application of a new temporary abdominal wound closure,vacuum system for temporary management of the open abdomen.

METHODSVacuum pack system consisted of polyethylene sheet,surgical towel,silicone drain, adhesive plastic drape. Clinical data of the patients undergoing exploratory celiotomy were recorded,and the indications for such temporary abdominal closure and its complications were reviewed.

RESULTSThirteen trauma patients underwent such vacuum abdominal closure for 15 times, including 5 times (33.3%) for increased intra- abdominal pressure so that tension-free fascial closure was unable to achieve, 4 times (26.7%) for reexploration, 2 times (13.3%) for damage control, and 4 times (26.7%) for combined factors. Finally, seven patients (53.8%) received direct closure and 5 patients (38.5%) received skin grafting after granulation because the defect could not be closed directly. One patient (7.7%) died before abdominal closure was attempted. None of the patients developed enterocutaneous fistula and evisceration. Three patients (23.1%) developed intra-abdominal abscess.

CONCLUSIONSThe vacuum pack is a better temporary abdominal wound closure device, and primary closure can be achieved in most of the patients. The technique is simple and easily mastered with a low complication rate.

OBJECTIVETo evaluate the clinical and radiographic results of total lumbar disc replacement with SB Charité III prosthesis.

METHODSFrom Dec 1999 to Dec 2006, total lumbar disc replacement with SB Charité III prosthesis was performed in 65 patients affected with degenerative lumbar disc disorders. Among these patients, 48 (52 prosthesis) were followed up for more than two years (from 2.0 to 7.5 years). There were 22 males and 26 females with an average age of 43 years old (from 36 to 58 years). The diagnosis was lumbar disc herniation with low back pain in 34 patients, discogenic low back pain in 9 patients and failed lumbar disc surgery in 5 patients. All patients underwent standard anterior procedure under general anesthesia. One level replacement was done in 44 patients (L3,4 in 3, L4,5 in 23 and L5-S1 in 18), and two level procedures in 4 patients (L3,4/L4,5 in 1 and L4,5/L5-S1 in 3). Clinical and radiographic results of these patients were evaluated at each follow-up time (1, 3, 6, 12, 24 months after operation and the latest).

RESULTSThe average visual analogue scales score for pain was 9.3 before operation, changed to 4.3 one month after operation, further declined to 2.6 two years after operation and finally to 1.8 at the latest follow-up evaluation. Meanwhile, the average Oswestry Disability Index was 45.8 before operation, 28.6 one month after operation, 12.5 two years after operation and 8.2 at the latest followup evaluation. All operated levels but one maintained mobile and there was no significant loss of range of motion observed. Complications such as implant dislocation or significant subsidence of the prosthesis occurred in none case of this group. All patients but one (98%) were satisfied with the surgery at the latest follow-up evaluation.

CONCLUSIONSTotal lumbar disc replacement is an effective method for the treatment of degenerative disc disorders. Its long-term outcome remains to be verified.
