Objective To explore the effects of Tangzhiping granules on the blood glucose and IGF-Ⅰ in T2DM rats.Methods 40 SPF grade Wistar rats whose weight were about (200±20)g were selected as the subjects for this study,one half were male and another half were female.After be adapted to the normal food for 1 week,8 rats were selected randomly from all of rats following their weight as the blank group (ordinary feed).The remaining the others were fed with the high-fat and high-sugar food.The 6th week,the other rats would be undergo intraperitoneal injection once in left lower belly with 40 mg/kg streptozotocin (STZ),and enable them to become T2DM rats.The 8th week,we would select successful animal models 32 which were divided randomly into a modle group,a Tangmaikang (TMK) granules group,a Tangzhiping granules (TZP)group.The 12th week,we would execute all of rats and collect the blood serums which were tested for the blood glucose and IGF-Ⅰ.Results () Compared model group with blank group,the levels of the blood glucose of the model group increased to (28.33±0.50)mmol/L,while the IGF-Ⅰ decreased to (3.40 ± 0.83) pg/ml,which showed the model of type 2 diabetic rats was successfully set up.② The levels of the blood glucose of the Tangzhiping granules group and Tangmaikang granules group were lower than that of the model group to (15.06±0.39)mm ol/L,(20.12±0.58)mmol/L,but the levels of the IGF-Ⅰ were higher to (9.39±2.91)pg/ml,(5.58± 1.09)pg/ml,which implied that each group of pharmacological treatment had a good effect.③ The level of the blood glucose and IGF-Ⅰ of the Tangzhiping granules group was also significantly different from that of the Tangmaikang granule group,the therapeutic effect of Tangzhiping granules group was better than that of Tangmaikang granules group.Conclusion Tangzhiping granules can reduce the blood glucose of T2DM rats.And also can increase IGF-Ⅰ of T2DM rats.Tangzhiping granules can improve the various symptoms of diabetes mellitus at the same time.

For uncontrolled hemorrhagic shock the traditional method and target of resuscitation may be harmful. The existing data supported a strategy of less aggressive interventions to those shock with uncontrolled hemorrhage until a decisive surgery begin. The choice of liquor for resuscitation remains in controversy. A combined application of crystalloid and colloid liquor seems to be reasonable and may be accepted by most physicians. It should be noted that the new resuscitation strategy may not be suitable to some kinds of trauma, such as traumatic brain injury, and its long-term effects on to the prognosis should be further evaluated.

AIM: To explore the effect of L-arginine (L-Arg) on the arrhythmia induced by ischemia/reperfusion (IR) of the right coronary artery in rabbits. METHODS: 48 healthy adult rabbits were divided into 4 groups (n=12 of each) randomly: IRa group (120 min reperfusion after 30 min ischemia), IRb group (120 min reperfusion after 120 min ischemia), IRa+L-Arg group and IRb+L-Arg group. I/R model was established by occluding and loosening the root of the right coronary artery in rabbits. The changes of ECG and arrhythmia were recorded and graded. RESULTS: ① The longer time of IR was, the higher the score of the arrhythmia was found. The incidence of atrial-ventricular block (AVB), sinus-atrial block (SAB), even sinus arrest were detected and aggravated gradually. ② The incidence of AVB was decreased and from Ⅲ?→Ⅱ?→Ⅰ? markedly, some of sinus and atrial arrhythmia were transformed into sinus rhythm gradually, and all of the arrhythmia scores in IRa group were decreased significantly as compared with the same time phases of IRb group (P

Objective To explore the diagnosis and treatment of clinical possible organizing pneumonia.Methods The medical records of 31 patients with clinical probable organizing pneumonia were retrospectively analyzed.The clinical presentation,radiographic results and treatment were collected and analyzed.Results Thirty-one patients with non-response to antibiotics were preliminary diagnosed as organizing pneumonia.By percutaneous lung biopsy or transbronchial lung biopsy the tuberculosis,fungi,suppurative inflammation,lung cancer and other diseases were ruled out in 24 patients,and 7 patients were diagnosed by perfect effect of corticosteroids treatment.Twenty-one patients had typical CT findings.All the patients responded rapidly and completely to the administration of corticosteroids.Six patients relapsed after the reduction or stop of corticosteroid in a follow-up time of 6-25 months.Conclusions Non-response to antibiotics,the typical imaging findings and lung biopsy ruling out other diseases are important for diagnosing organizing pneumonia.Rapid response to administration of corticosteroids may be helpful to the diagnosis.Decreasing the dose of corticosteroid too early may cause recurrence of organizing pneumonia.

Objective To investigate whether human breast milk may bind to hepatitis B surface antigen (HBsAg) and its characteristics.Methods Breast milk samples from five women with negative HBsAg and hepatitis B surface antibody (anti-HBs) at one to two months post delivery were fractioned into cream and skimmed milk by centrifugation.The human breast milk and each fraction as well as cow and goat milk samples,served as controls,were separately incubated with highly purified yeast recombinant HBsAg,followed by determination of their binding capability to HBsAg by enzyme linked immunosorbent assay (ELISA) and the inhibition rate for binding of HBsAg to anti-HBs by quantitative chemiluminescence microparticle immunoassay.After boiled for 1 min or pasteurized in 65 ℃ for 30 min,the thermal stability of the active components of milk was detected.One-way ANOVA and SNK tests were performed for statistical analysis.Results The operative concentration of HBsAg was 0.1 μg/ml.Breast milk from all five women showed significantly better binding capability to HBsAg than cow or goat milk (1.306±0.300 vs 2.157±0.150 and 2.232±0.093,F=34.303,P＜0.01).The quantitative experiments showed that the inhibition rate of human breast milk was higher than that of the control group [(74.26± 17.26)％ vs (0.00±5.50)％,F=57.806,P＜0.01].The binding ability to HBsAg of skimmed milk was comparable with that of whole milk,indicating milk protein(s) played critical roles in binding to HBsAg (0.877 ± 0.486 vs 0.513 ± 0.069 and 0.376 ± 0.146,F=44.475,P＜0.01).After boiled for 1 min or Pasteurization,the binding ability to HBsAg of whole breast milk remained,but that of skimmed milk went down (F=16.598,P＜0.01).Both whole breast milk and skimmed milk could inhibit the binding of HBsAg to anti-HBs (F=278.341 and 269.408,both P＜0.01).Conclusions The inhibition of binding to HBsAg by human breast milk indicates that human milk may interact with HBsAg.The active components mainly exist in milk proteins and are thermal stable.

Objective To explore the effect of PDCA circulation on the effective utilization of the disposable articles in the operating room.Methods 9,362 aseptic articles for 446 operations in the departments of general surgery and hepatobiliary surgery during January to May 2012 were put in the pre-experiment group,in which PDCA circulation was not used.Another 11,973 articles for 501 operations in the same departments during June to November 2012 were set as the post-experiment group,in which PDCA circulation was used.The two groups were compared in terms of the effective utilization rate and the degree of doctor’s satisfaction with the nurses in the operation room.Result After the implementation of PDCA circulation,the effective utilization rate and the degree of doctor’s satisfaction were both significantly higher than before the implementation(both P<0.05).Conclusion PDCA circulation for the management of sterile disposable articles in the operation room may effectively improve the utilization rate of disposable articles, reduce wasting of articles and safe resources.

Objective To apply the virtual reality in balance function training for Parkinson's Disease (PD). Methods From October, 2013 to January, 2016, 31 patients with balance disorders after PD were divided into two groups:the treatment group (n=17) received virtual reality balancing games training, while the control group (n=14) received routine balance training. They were assessed with Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), static fall index (SFI), limits of stability (LOS), dynamic fall index (DFI) and modified Barth-el Index (MBI) before and four weeks after treatment. The frequency of falls in the next six weeks was recorded. Results The scores of BBS, TUGT, SFI, LOS, DFI and MBI improved significantly in both groups after treatment (P<0.05), and improved more in scores of BBS (t=2.095), TUGT (t=-2.091), DFI (t=-2.182), LOS scores (t=2.202) and MBI (t=3.036) in the treatment group than in the control group (P<0.05). There was positive correlation between scores of BBS and MBI (r=0.899, P<0.001). The frequency of falls was less in the treatment group than in the control group (P<0.05). Conclusion Virtual reality balance training can improve the balance function for PD.

Objective To explore the effect of electroacupuncture at Quchi (LI11), Zusanli (ST36) on differentiation of neural stem cells after cerebral ischemia-reperfusion in rats. Methods Thirty-six male Sprague-Dawley rats were randomly divided into sham group (n=12), model group (n=12) and electroacupuncture group (n=12). The latter two groups were occluded the left middle cerebral arteries for 90 min-utes and reperfused. The electroacupuncture group received electroacupuncture at Quchi and Zusanli acupoints for 21 days. They were evalu-ated with modified Neurological Severity Scores 7, 14 and 21 days after electroacupuncture. Their infarct volumes were tested with MRI T2WI 21 days after electroacupuncture, while the differentiation of neural stem cells was observed with double-immunopositive BrdU/Dcx and BrdU/NeuN. Results Compared with the model group, the neurological deficits score improved in the electroacupuncture group in all the time points (P<0.05). The infarct volumes decreased in the electroacupuncture group (P<0.05), with less number of BrdU+/Dcx+cells in subventricular zone (P<0.001) and more number of BrdU+/NeuN+ cells in peri-infarct cortex (P<0.001) 21 days after electroacupuncture. Conclusion Electroacupuncture at Quchi and Zusanli acupoints can improve neurological function and decrease the infarct volumes in rats after cerebral ischemia-reperfusion, which may be associated with promoting differentiation of neural stem cells to neurons.

Objective To investigate the effect and underlying mechanism of radioactive 125I seed implantation on the angiogenesis of transplanted human lung adenocarcinoma in nude mice.Methods An animal model of transplantd human lung adenocarcinoma was established by subcutaneous implanting A549 cells into nude mice.Twenty four tumor-bearing nude mice were randomly divided into 4 groups with different irradiation doses of blank control (without any treatment) and 0 MBq,22.2 MBq,29.6 MBq and by embedding radioactive 125I seeds with an 18 G implant needle.Tumor volumes were measured every 4 days until all mice were terminated 30 d later and the tumor growth curve was drawn.The microvessel density (MVD) in the tumor tissue was detected by immunohistochemistry S-P assay.The mRNA and protein levels of VEGF and HIF-1α of each group were detected by RT-PCR and Western blot,respectively.Results After embedding of 125I seeds,the tumor volumes of 22.2 MBq group (886 ± 97) and 29.6 MBq group (590 ± 107) were significantly smaller than those of control group (2 297 ± 149) at 54 d after administration (q =14.117,17.075,P ＜ 0.05),but there were no significant differences among 0 MBq group and control group,22.2 MBq and 29.6 MBq groups (P ＞ 0.05).The immunohistochemical CD34-positive staining demonstrated that MVD in 22.2 MBq group (522 ± 119) and 29.6 MBq group (491 ± 121) were decreased significantly compared with control group (922 ± 260) (q =4.826,5.197,P ＜0.05),but there were no significant differences among 0 MBq and control groups,22.2 MBq and 29.6 MBq groups(P ＞0.05).The mRNA expressions of VEGF and HIF-1α in 22.2 MBq group (0.279±0.0659,0.370 ±0.0857) and 29.6 MBq group (0.215 ±0.0620,0.278 ±0.0651) were significantly lower than those in the control group (q VEGFmRNA =18.881,17.211,q HIF-1αmRNA =15.376,14.733,P ＜0.05),but there were no significant differences among 0 MBq and control groups,22.2 MBq and 29.6 MBq groups(P ＞0.05).At the same time,the expression levels of VEGF and HIF-1α protein after 125I seed implantation were also obviously decreased in 22.2 MBq and 29.6 MBq groups (qvEGr =5.848,6.263,q HIF-1α =6.560,7.576,P ＜ 0.05),and no significant difference between 0 MBq and control groups(P ＞ 0.05) and between 22.2 MBq and 29.6 MBq groups (P ＞ 0.05).Conclusions Interstitial implantation with 125I seeds may potently inhibit angiogenesis in human lung adenocarcinoma xenografts of nude mice.
