  • Research progress on early pulmonary rehabilitation of acute exacerbation or critical illness

    Pulmonary rehabilitation is a comprehensive intervention based on a thorough patient assessment followed by patient-tailored therapies, which include, but are not limited to, exercise training, education, and behavior change, designed to improve the physical and psychological condition of people with chronic respiratory disease and to promote the long-term adherence of health-enhancing behaviors. It has been proven beneficial in reducing dyspnea and improving functional capacity and quality of life for patients with stable chronic respiratory disease. However, recent randomized clinical trials reported conflicting results on the timing of intervention, protocol and effectiveness of acute exacerbation or intensive care unit pulmonary rehabilitation to improve patient outcomes. We should find a balance between " dynamic” and " static” to maximize the benefit of patients from early pulmonary rehabilitation.

  • Clinical Application of Recombinant Human Growth Hormone on Obstructive Jaundice

    Objective To observe therapeutical effect of recombinant human growth hormone (rhGH) on postoperative obstructive jaundice. Methods Fourtyeight patients were divided into two groups randomly: control group with 30 patients and rhGH group with 18 patients. After operation, subcutaneous injection of rhGH was administered 8 U/d for a week. At the same time, parenteral nutrition was given to both groups until the patients could eat and drink. Biochemistry examination, endotoxin, tumor necrosis factor, sIL-2R and nutritional status were all measured at following states: before operation 1, 7 and 14 days after operation. Results Body weights of rhGH group on the fourth day after operation and that of control group on the seventh day after operation increased, but the increasing tendency of rhGH group was more prominent than the control group. For blood sugar 7 days after operation, the level of rhGH group was higher than that of control group (P<0.05). The level of serum albumin, transferrin, prealbumin in rhGH group was higher than that of control goup (P<0.05). Blood serum total bile acid,total cholesterol, low density lipoprotein,glutamicoxal acetic transaminase, transglutaminase, total bilirubin, endotoxin, tumor necrosis factor and sIL-2R were all decreased compared with control group (P<0.01). However, no significant difference was observed in renal function and electrolute between the two groups.Conclusion An improvement of nutrition status and immunologic function can be observed in obstructive jaundice patients after the postoperative administration of rhGH.

  • Experimental Research of Recombinant Human Growth Hormone on Obstructive Jaundice

    ObjectiveTherapeutical effect of recombinant human growth hormone (rhGH) on obstructive jaundice and internal and external drainage was observed.MethodsNew Zealand white rabbits were randomly divided into groups below: obstructive jaundice internal drainage plus rhGH group, obstructive jaundice internal drainage plus NS group, obstructive jaundice external drainage plus NS group, and obstructive jaundice external drainage plus rhGH group. After the establishment of obstructive jaundice model, rhGH was used in the above groups. Subcutaneous injection of rhGH 0.2 IU/kg was given twice a day. Isovolume NS was used on the control groups. Full set of endotoxin, tumor necrosis factor, sIL2R and nutritional status were estimated before the model establishment, and 14 days after the model established, 14 days after internal and external drainage.ResultsFour days after internal and external drainage, body weight of therapy groups was increased compared with control groups (P<0.05). Seven days and ten days after obstructive jaundice, blood sugar of therapy groups rised compared with control groups (P<0.05). Albuminate, siderophilin and prealbumin of therapy groups were all observed an increase after 14 days after obstructive jaundice, and 14 days after internal and external drainage (P<0.01). Blood total cholesterol, low density lipoprotein and omni bile acid of therapy groups after 14 days of obstructive jaundice were increased apparently (P<0.05). Blood glutamicoxal acetic transaminase, transglutaminase, total bilirubin, blood uria nitrogen, creatinine and uric acid of therapy group after 14 obstructive jaundice days were increased (P<0.05). Ca2+ of therapy groups 14 days after obstructive jaundice, 14 days after internal and external drainage rised as compared with control groups (P<0.05). However, K+,Na+ of therapy groups 14 days after external drainage decreased (P<0.05). An increasing tendency of sIL2R was observed in control groups 14 days after obstructive jaundice(P<0.05) and ET,αTNF,sIL2R of control groups was decreased 14 days after internal and external drainage (P<0.01).ConclusionAfter rhGH is used in obstructive jaundice and internal and external drainage, an improvement of nutritional status and immunological function can be observed.

  • AN EXPERIMENTAL STUDY ON EFFECT OF AUTOLOGOUS PLATELET-RICH PLASMA ON TREATMENT OF EARLY INTERVERTEBRAL DISC DEGENERATION

    Objective Platelet-rich plasma (PRP) can stimulate intervertebral disc cell proliferation, promote extracellular matrix synthesis, and inhibit annulus fibrosus cell apoptosis. To investigate the effects of autologous PRP on the treatment of the early intervertebral disc degeneration (IDD) so as to provide the experimental basis for its clinical application. Methods Forty-five healthy New Zealand white rabbits (male or female, weighing 2.5-3.0 kg) were randomly divided into the experimental group (n=15), the control group (n=15), and the sham group (n=15). PRP was prepared from the arterial blood of rabbit’s ears of the experimental group with Landesberg’s method. The platelet concentrations in both whole blood and PRP were detected. The rabbit model of early IDD was established by annulus fibrosus puncture (L4, 5, L5, 6) in both the experimental group and the control group; 100 ?L autologous PRP and 100 ?L PBS were injected into the degenerative intervertebral discs respectively after 2 weeks of models creation. In sham group, intervertebral discs were separated and exposed without treatment. The general conditions of the rabbits were observed after building models; at 2 weeks after degeneration, 1 and 2 weeks after intervention, 5 rabbits were selected randomly from each group respectively for MRI observation, histological observation by using HE staining and collagen type II immunohistochemical staining. The signal of lumbar MRI was assessed and the contents of collagen type II were detected. Results The platelet concentration of PRP was about 4.92 times as much as that of the whole blood. All the animals survived to the end of the experiment. At 2 weeks after degeneration, a lower T2 signal was observed in both the experimental group and the control group; the nucleus pulposus cells decreased and extracellular matrix degenerated; and the expression of collagen type II decreased in both the experimental group and control group. The degenerative grade of lumbar MRI in the experimental group and control group were significantly higher than that in the sham group (P lt; 0.05), and the content of collagen type II were significantly lower than that in the sham group (P lt; 0.05). At 1, 2 weeks after intervention, disc degeneration in the experimental group was significantly lower than that in control group (P lt; 0.05), and significant difference was found between experimental group and sham group (P lt; 0.05). The nucleus pulposus cells and chondroid matrix in the experimental group were more than those in the control group, showing slight stromal fibrosis; but the expression of collage type II was significantly higher than that in the control group (P lt; 0.05). Conclusion The disc injection of autologous PRP may terminate or even reverse the progress of rabbit early IDD, which may be associated with the role of multiple growth factors of PRP in regulating cell function, improving the tissue microenvironment, and promoting tissue regeneration.

  • EFFECT OF PLATELET-RICH PLASMA ON TENDON HEALING

    Objective Platelet-rich plasma (PRP) secretes many growth factors, including transforming growth factor β1 (TGF-β1), platelet derived growth factor, vascular endothl ial growth factor, insul in-l ike growth factor 1, and so on, which can promote cell prol iferation, chemotaxis, and collagen synthesis in wound heal ing. To investigate the effects of PRPon the tendon heal ing, and to explore the mechanism of action so as to provide the experimental basis for the tissue engineered tendons. Methods Forty healthy New Zealand white rabbits, weighing 2.5-3.0 kg and male or female, were randomly divided into the experimental group (n=20) and the control group (n=20). PRP was prepared from arterial blood of rabbit’s ears through twice centrifugation method of Landesberg. The platelet concentrations of whole blood and PRP were determined. The right achilles tendons of the rabbits were transected to make rupture models. In experimental group, the tendon was sutured after PRP (0.5 mL) was immediately appl ied at repair site. In control group, the tendon was sutured directly after transection. At 1, 2, 4, and 6 weeks after operation, the tendons of 5 rabbits in each group were harvested for morphological, histological, and immunohistochemical observations; the fibroblast counting, the content of collagen fibers, and the expression of TGF-β1 were detected. Results The concentration of platelet of PRP was 4.03 times of whole blood. All the animals survived till the end of the experiment, and the incision healed well. No death, infection, and other compl ications occurred. With time, the tendons almost healed in 2 groups, and the fibrous tissue at anastomosis site was more remarkable in control group than in experimental group. The histological observation showed significant differences in fibroblast counting at 1, 2, and 4 weeks after operation between 2 groups (P lt; 0.05), while no significant difference at 6 weeks (P gt; 0.05). The contents of collagen fibers in the parenchyma at repair site in experimental group were significantly higher than those in control group at each time point (P lt; 0.05). Immunohistochemistry staining showed the expression of TGF-β1 in experimental group was upregulated at 1 week and 2 weeks and reached the peak at the 2nd week, and subsequently downregulated at 4 and 6 weeks in comparison with the control group, showing signficant differences between 2 groups at each time point (P lt; 0.05). Conclusion PRP can facil itate rabbit’ s tendons heal ing and significantly improve the heal ing qual ity, which may be associated with its advancing the peak time of the TGF-β1 expression in tendon.

  • Bariatric Surgery versus Conventional Medical Therapy for Obese Patients with Type 2 Diabetes: A Meta-Analysis

    Objective To systematically evaluate the effectiveness of frequently-used bariatric surgery versus conventional medical therapy for obese patients with type 2 diabetes. Methods Such databases as The Cochrane Library (Issue 12, 2012), PubMed, CNKI, CBM, VIP and WanFang Data were searched to collect the randomized controlled trails (RCTs) about frequently-used bariatric surgery vs. conventional therapy for obese patients with type 2 diabetes. The retrieval time was from inception to May, 2012. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and evaluated the quality. Then the meta-analysis was performed using RevMan 5.1.2 software. Results A total of three RCTs involving 340 patients were included finally. The results of meta-analysis showed that, compared with conventional medical therapy, bariatric surgery could improve the diabetes remission, decrease both glycated hemoglobin level and patient’s weight. At the same time, the postoperative complications were fairly mild. Conclusion Frequently-used bariatric surgery is superior to conventional medical therapy when treating obese patients with type 2 diabetes, and it deserves to be recommended in clinic. However more studies are required to further confirm this conclusion because of the quality and quantity limitation of the included studies.

  • Clinical Experience on Laparoscopic Radical Surgery in Patients with Advanced Distal Gastric Cancer (Report of 26 Cases)

    ObjectiveTo summarized the clinical experience on laparoscopic radical surgery in patients with advanced distal gastric cancer. MethodsThe clinical data of 26 patients with advanced distant gastric cancer undergoing laparoscopic gastrectomy were retrospectively analyzed. ResultsLaparoscopic distal gastrectomy was performed successfully in all patients. The operation time was (283.2±27.6) min (270-450 min) and the blood loss was (178.4±67.4) ml (80-350 ml). The time of gastrointestinal function recovery was (2.8±1.2) d (2-4 d), out of bed activity time was (1.5±0.4) d (1-3 d) and liquid diet feeding was (3.5±1.4) d (3-4 d). The hospital stay was (10.0±2.6) d (7-13 d). The number of harvested lymph nodes was 11 to 34 (17.8±7.3). The distance from proximal surgical margin to tumor was (7.0±2.1) cm (5-12 cm) and the distance from distal surgical margin to tumor was (5.5±1.8) cm (4-8 cm), thus surgical margins were negative in all samples. All patients were followed up for 3-48 months (mean 18.5 months), two patients with poorly differentiated adenocarcinoma died of extensive metastasis in 13 and 18 months, respectively, and other patients survived well. ConclusionsLaparoscopic radical gastrectomy with D2 lymphadenectomy for advanced gastric cancer is safe and feasible. However, the advantage of laparoscopic technique over the conventional open surgery requires further study.
