Objective To observe the inhibitory effect of tumstatin related peptide T3 mediated by short peptide to osteosarcoma vascular. Methods Through MTS assay, wound healing assay, the inhibitory effect of targeting-T3 peptide and T3 peptide on the human umbilical veil endothelial cell was studied in vitro. After the preparation of 50 nude mice model bearing osteosarcoma, the nude mice bearing too large or too small tumors were eliminated and the left ones were divided into 4 groups (6 animals for each group: T3 peptide, targeting-T3 peptide, CTX, PBS) randomly. Through weight of tumor, histopathologicol slice and immunohistochemical methods. The inhibitory action of targeting-T3 peptide and T3 peptide on the neoge-netic vascular of osteosarcoma implanted in nude mouse was studied. Results In vitro, both T3 peptide and targeting-T3 peptide effectively inhibited the proliferation of human umbilical veil endothelial cell. In the experiment of vivo, the average weight of tumor of targeting-T3 peptide group was (1.104?.247) g, the average weight of the T3 peptide group was (1.484?.369) g. There was the statistical difference in tumor inhibition on the osteosarcoma betweent the targeting-T3 group and T3 group (F=16.353, P=0.000). The positive rate of vascular endothelial growth factor and metastasis in the lung in the targeting-T3 peptide group all descended than the T3 peptide group. Conclusion Because of the short peptide to osteosarcoma vascular, targeting-T3 peptide could significantly restrain the development of osteosarcoma. Coupling short peptide to T3 peptide increase the selective binding of T3 peptide to osteosarcoma vascular.

Objective To summarize preliminary experiences on complete video-assisted thoracoscopes lobectomy for patients with non-small cell lung cancer.Methods From October 2009 to March 2012,42 patients with non-small cell lung cancer were treated with complete video-assisted thoracoscopes lobectomy.Tumors located in the left upper lobectomy in 7 cases,10 cases of left lower lobectomy,9 cases of upper right lung,4 cases of right lung,12 cases of lower right lobectomy.Preoperative cTNM stage was Ⅰ-Ⅱ (T1N0M0-T2N1M0),the size of tumor was ＜ 5 cm,no obvious lung and mediastinal lymph node enlargement or pleura hypertrophy.Results All operations were successful.There were (9.5 ± 3.2) pieces of lymph nodes removed.Nz lymph node cleaning was more than 3 groups,the average was 3.3 groups.The operation time was 100-400 (220 ± 37) min,blood loss was 120-700 (150 ± 63) ml,duration of drainage was 3-12(4.5 ± 2.1) d.The postoperative hospital stay was 9-31 (12.2 ± 5.0) d.Conclusion Video-assisted thoracoscopes lobectomy is technically feasible and safe,but the operation indications should be paid special attention.

Objective To explore the influnce on the endothelin-1 (ET-1) and clinical application value of continuous blood purification (CBP) on the treatment of severe craniocerebral injury with the neurogenic pulmonary edema (NPE).Methods All data about sixty patients with NPE were prospectively studied.These 60 patients were randomly (random number) divided into control group (n =30) and treatment group (n =30).In control group,patients were rapidly given with lowering intracranial pressure,mechanical ventilation,calming,antibiotic therapy and so on.In the treatment group,patients received CBP integrated with routine treatment.On admission and 72 h posttreatment,ET-1,static lung compliance and oxygenation index were observed.Time of mechanical ventilation support,incidence rates of multipal organ dysfunction syndrome (MODS) were compared between two groups.The paired t-test was used for the amount data within the group.Chi-square was used for the constitute ratio and incidence ratio of the each relevant information.P ＜ 0.05 was considered statistically significant.Results Compared to the control group,the level of ET-1 was decreased significantly in the treatment group [(48 ± 10) ng/L vs.(85 ± 14) ng/L] after 72 h post-treatment,while static lung compliance [(60.9 ± 2.3) mL/cmH2O vs.(31.4 ±4.8) mL/cmH2O] and oxygenation index [(317 ± 11) mmHg vs.(192 ± 14) mmHg] increased significantly (P ＜ 0.05).In treatment group and control group,the time of respirator intervention were [(6.0 ± 2.1) d vs.(11 ± 3.2) d],and the statistical significance was shown (P ＜ 0.05).Compared to the control group [56.7％ (17/30)],incidence rate of MODS [20.0％ (6/30)] was lower in treatment group (P ＜ 0.05).Conclusions CBP combined with routine treatment,which can remove ET-1 effectively,improve oxygenation,reduce the time of mechanical ventilation support and incidence rate of MODS.

The effect of micronutrient complex preparations on dark adaptation function was studied in human body. Sixty-four young students, 18 to 20 years of age, were divided into four groups. Under the normal dietary condition, the experimental groups were supplemented with different microcutrient complex preparations for two weeks.Before and after the experiment serum vita- min A and zinc level, quick dark adaptation time, near-sighted in dim light time and absolute threshold were determined. It was found that dark adaptation was much improved in the group supplemented with adequate vitamin A as well as other vitamins and zinc. So we suggested that micronutrient complex preparation should be given to operators who will concentrate their sight in low illuminance for maintaining their visual function.

Aspirin (AS) has been widely used globally for preventing incidence of cardio-cerebral ischemic disease for nearly 100 years.The people who takes AS for long term may reach several hun-dred million,but many persons were died from interned bleeding.We found salvianolic acids (salvianolic acid B 57％,salvianolic acid A 1％,rosmarinic acid,35％,SA)was much better than AS in preventing in-cidence of cardio-cerebral ischemic disease,and may avoid hemorrhage risk in clinical application.The research are summary briefly as follows: (1) both AS and AS have same anti-platelet aggregation ef-fect,but their mechanism is different.AS inhibited both TXA2 and PGI2,SA inhibited TXA2only;(2)For established thrombosis,SA could dissolved it, AS showed no effect. The thrombolytic mechanism of SA has been elucidated. (3) In SHRSP rats, the incidence of stroke and death rate in SA group was distinct less that of AS group;(4)In MCAO rats,SA and Sal B decreased stroke index and neural im-pairment. AS showed no such ability; (5) There is microcirculatory disturbance in cardio-cerebral isch-emic disease. SA could improve circulatory disturbance induced by LPS, adrenaline, ROS and I/r. there is no any paper reported AS could have beneficial effect on above mentioned microcirculatory dis-turbance models;(6)Hyperlipidemia is an independent risk factor for cardio-cerebral vascular disease. SA could significant hypolipidemic effect which is similar to that of statins(atovastin and simvastin)and ten times stronger than omega-3.AS has no inhibitory effect on hyperlipidemia.(7)Thereis overproduc-tion of ROS induced by ischemic/reperfusion in cardio-cererbal vascular disease.SA showed more ro-bust,anti-oxidant capacity than VitC,Vit E,melatonin,edalavone and resveratrol,etc.SA is one of the most powerful anti-oxidant in the world so far.(8)According to literatures,1/3 patients who take AS for long time will have hemorrhage, we found in normal rats and mice (coagulating and hemodynamics) SA had no apparent effect on coagulation system and this property of SA was confirmed in clinic trial with hundred thousand cases; (9) As well known, neurodegenerative disease are divided into acute and chronic neurodegenerative disease,and both have similar pathogenesis.We proved that SA could inhibit Aβ aggregation and fiber formation, inhibit tau hyperphosphorylation induced by OA and p25/CDK5,as well as increase neurogenesis and angiogenesis.More importantly,SA showed not only pre-ventive effect on cardio-cerebral vascular diseases. SA has been finished clinical trial phase I-IV for treatment of stroke.The therapeutic effect of SA is characterized by inducing multi-target effect and in-hibit pathogenesis of early,middle and late stage of stroke.SA as anti-stroke new drug was approved by the state food and drug administration of China in 2011.

OBJECTIVETo study the clinical effect of combined treatment with gamma-globulin, corticosteroids, immunosuppressor and Chinese medicines on systemic lupus erythematosus (SLE) patients characterized by hypoplastic bone marrow (HBM).

METHODSNineteen patients were randomly assigned to two groups, the treated group (10 cases) received combined therapy of prednisone and cyclophosphamide (CTX) plus Chinese medicine Langchuang Recipe after being treated impactively with gamma-globulin. The control group (9 cases) was treated with prednisone and CTX. Changes of hypoplastic bone marrow, peripheral white blood cell (WBC), complement C3, 24 h urinary protein excretion, and lupus activity index (LAI) were observed, and a follow-up was carried out for one year.

RESULTSAfter one-month treatment, the bone marrow hypoplasia was relieved significantly in the treated group (P < 0.05, P < 0.01), showing an improvement superior to that in the control group (P < 0.05, P < 0.01); after three months treatment, the level of complement C3 increased (P < 0.01), while the 24 h urinary protein excretion and LAI decreased in the treated group (P < 0.05), showing significant difference as compared with those in the control group (P < 0.05, P < 0.01). In the follow-up period, 3 cases withdrew from the trial because of infection and 4 cases manifested full moon-face and acne in the control group, while no adverse reaction was found in the treated group.

CONCLUSIONTreatment with integrated Chinese and Western medicine could effectively improve bone marrow hypoplasia, alleviate the clinical symptoms, suppress the activity of lupus in patients, and reduce the adverse reaction of treatment, showing a superiority to the treatment with prednisone combining with CTX.

OBJECTIVETo explore the protection of high intensity microwave radiation on hypothalamo-pituitary-adrenal axis (HPAA) activity and hippocampal CA1 structure in rats and the protectiveeffect of Qindan Granule (QG) on radiation injured rats.

METHODSTotally 48 Wistar rats were randomlydivided into 8 groups, i.e., the normal control group, post-radiation day 1, 7, and 10 groups, 7 and 10days prevention groups, day 7 and 10 treatment groups, 6 in each group. Rats in prevention groups wererespectively administered with QG liquid (1 mL/100 g, 4. 75 g crude drugs) for 7 days and 10 days bygastrogavage and then microwave radiation. Then preventive effect for radiation injury was statisticallycalculated with the normal control group and the post-radiation day 1 group. Rats in treatment groupswere firstly irradiated, and then administered with QG liquid (1 mL/100 g, 4.75 g crude drugs). Finally preventive effect for radiation injury was statistically calculated with the normal control group, post-radiation day 7 and 10 groups. Contents of corticotrophin releasing hormone (CRH), beta endorphin (beta-EP), adrenocorticotropic hormone (ACTH), and heat shock protein 70 (HSP70) were detected. Morphological changes and structure of hippocampal CA1 region were observed under light microscope.

RESULTSCompared with the normal control group, contents of CRH and beta-EP significantly decreased in each radiation group. Serum contents of ACTH and beta-EP significantly increased in post-radiation day 1 and 7 groups (P < 0.05). Compared with radiation groups, beta-EP content in serum and pituitary significantly increased, and serum ACTH content significantly decreased in prevention groups (P < 0.05). Pituitary contents of CRH and beta-EP significantly increased in prevention groups. Serum contents of ACTH, beta-EP, and HSP70 were significantly lower in day 7 treatment group than post-radiation day 7 group (P < 0.05). Morphological results showed that pyramidal neurons in the hippocampal CA1 region arranged in disorder, with swollen cells, shrunken and condensed nucleus, dark dyeing cytoplasm, unclear structure. Vessels in partial regions were dilated with static blood; tissues were swollen and sparse. In prevention and treatment groups pathological damage of hippocampal CA1 region was obviously attenuated; neurons were arranged more regularly; swollen, pycnotic, or deleted neuron number were decreased; vascular dilatation and congestion was lessened.

CONCLUSIONQG could affect HPAA function and activity of high intensity microwave radiated rats, showing certain preventive and therapeutic effects of microwave radiated rats by adjusting synthesis and release of partial bioactive peptides and hormones in HPAA, improving pathological injury in hippocampal CA1 region.
