Aim To explore the role of nicotinamide adenine dinucleotide phosphate ( NADPH ) oxidase in high glucose-induced injury in H9c2 cardiac cells. Methods H9 c2 cardiac cells were exposed to differ-ent concentrations of high glucose(5. 5 mmol·L-1 ,11 mmol · L-1 ,22 mmol · L-1 ,33 mmol · L-1 ,44 mmol ·L-1 , 55 mmol · L-1 ) for 24 h and different time pints of high glucose(0 h,12 h,24 h,36 h,48 h,72 h) . Cell viability was measured by MTT colorimetry, the protein expression of Bcl-2 , Bax and NADPH oxi-dase submits such as p22 phox , p47 phox and p67 phox were determined by western blotting. Results H9c2 cardi-ac cells exposure to high glucose for 24 h showed on decrease in cell survival and the Bcl-2 expression while an increase in the Bax expression ( P<0. 05 ) . Moreo-ver, high glucose could markedly up-regulate the activ-ity of NADPH oxidase characterized by the enhanced expression of p22 phox , p47 phox and p67 phox ( P<0. 05 ) . Conclusion Activating NADPH oxidase may play an important role in high glucose-induced injury in H9 c2 cells.

Acupuncture has remarkable effects of pain relieving and functional restoration on injuries of soft tissue and joint due to military training. As more and more attention has been attached to the impact of psychological states and biorhythm disorder on the fighting ability of military staff, acupuncture has found its place in treating chronic fatigue, combat stress reaction, traumatic brain injury and post-traumatic stress disorder as well as regulating circadian rhythms. The therapeutic effect of acupuncture in military training-related physical damage and psychological trauma has already been proved by numerous clinical practices and researches. It is held that using acupuncture as an alternative could not only save medical resources, but also enhance the fighting ability of the army. However, the current clinical studies is facing the problem of limited sample size. Therefore, randomized controlled trials in large scale and multiple centers should be further carried out toward military staff, so as to provide more speaking evidences to the prevention and treatment of physical and psychological diseases.

Objective To establish a method for culturing neonatal mice cardiomyocytes, and construct an in vitro model of cardiomyocytes for assessing the cardiac toxicity of chemicals. Methods Hearts of neonatal mice of 1 day old were digested with enzyme mixture of trypsin/collagenase type Ⅱ/dispase and the cell suspensions were pre-plated to flask for a short time and then seeded on coated dishes. The cultured cells were treated with 5-fiuorine-deoxy-uridine(15 μg/ml)and uridine(35 μg/ml)to enrich cardiomyocytes that were identified according to the morphology and immunocytochemistry of α-actin antigen. Cardiac myocytes were incubated with 0-64 μg/ml of a fusarium mycotoxin butenolide(BUT) for 12 h. Cell viability was then evaluated by MTT assay. Microscopic observation showed that BUT induced significant morphological changes including cellular swelling, vacuolation and breakage of muscle fibers. Results It was found that 96% of the cultured cells were cardiomyocytes and the myocytes kept beating after 90 days of culture. Concentration-dependent decreases in cell viability following exposure of cardiac myocytes to BUT were observed. Conclusion The results indicated that relatively pure primary culture of neonatal mice cardiomyocytes is successfully established. BUT possesses the potential to induce myocardial toxicity.

We describe here a female patient who presented with a breast mass and giant abdominal mass. Fine needle aspiration cytology of the breast mass and histological examination after modified radical mastectomy confirmed metaplastic carcinoma of the breast. The epithelial components were formed by infiltrating ductal carcinoma with poor differentiation, and the sarcomatous components were formed by fibrosarcoma and osteosarcoma. Histological examination of the abdominal mass confirmed ovarian teratoma. The patient underwent modified radical mastectomy of the right breast and laparoscopic excision of the abdominal mass in the lower right quadrant. Having underwent six courses of chemotherapy, the patient is now in her tenth month after surgery and under follow-up, and she has no relapsed disease. These two diseases have never seen in one patient before. The case we report here provides some new data for research and clinical experience and it may also provide a new insight into the relationship between metaplastic breast carcinoma and ovarian teratoma.

AIM To investigate the effects of Tongmai Decoction on PLT,PAgR,D-D and TEG in elderly patients with intertrochanteric fracture in perioperative period.METHODS One hundred and fifteen recruited patient subjects were randomly divided into two groups.Fifty-seven cases in the control group were treated with Low Molecular Weight Heparins Calcium Injection,and 58 cases in the treatment group were intervened with both Low Molecular Weight Heparins Calcium Injection and Tongmai Decoction.The preoperative and postoperative dynamic changes of PLT,PAgR,D-D and TEG (R value,K value,alpha angle,MA),and adverse drug reactions in the two groups were detected 1,3,7 d prior to,and after the treatments,respectively.RESULTS No statistically significant difference between the two groups' PLT,PAgR and D-D contents were observed before the operation (P ＞ 0.05).The levels of PLT,PAgR and D-D in both groups increased one day after the operation with similar change degree (P ＞ 0.05).On the 3rd and 7th days after the surgery,the PLT,PAgR and D-D contents in the two groups began to drop,and the decline in the treatment group was more significant (P ＜ 0.05).No significantly different TEG (R value,K value,alpha angle,MA) between the two groups was noticed before the operation (P ＞ 0.05).Patients of both groups displayed their R value,K value decrease,and alpha Angle,MA increase (P ＞ 0.05) one day after the operation with similar change degree.Their R value,K value increased,and alpha angle,MA decreased,and as well as the statistically significant change between the two groups were discovered on the 3rd and 7th postoperative days (P ＜ 0.05).CONCLUSION Tongmai Decoction can effectively reduce blood hypercoagulability and prevent deep venous thrombosis in terms of PLT,PAgR,D-D and TEG (R value,K value,alpha angle,MA) improvement in elderly patients with intertrochanteric fracture in perioperative period.

Current studies have demonstrated that SLC38A1 proteins play a causal role in neoplastic cell transformation.The twofold aim of this study was to provide insight into whether a variance in the expression of SLC38A1 exists between human colorectal cancer and healthy human tissues and to determine how silencing or overexpressing the SLC38A1 gene could affect the proliferation,viability and migration of colorectal cancer cells.Immunohistochemical staining was used to analyze the expression of SLC38A1 in colorectal cancer tissues and adjacent normal mucosa in 77 patients who underwent surgical resection.The expression of SLC38A1 in colorectal cancer tissues and cell lines was detected using RT-PCR and Western blotting.Two colorectal cancer cell lines SW480 and HCT116 were used to examine whether silencing SLC38A1 with siRNA and overexpressing SLC38A1 with shRNA could affect cell viability and migration.As a result,the SLC38A1 protein was very low or undetectable in the normal colon mucosa.In contrast,strong staining of SLC38A1 protein was found in the cytoplasm in 79.2％ colorectal cancer samples.More pronounced SLC38A1 expression in colorectal cancer tissues was significantly associated with tumor node metastasis (TNM) stage.Inhibition of SLC38A1 reduced tumour growth and suppressed proliferation and migration of SW480 cells.In contrast,overexpression of SLC38A1 had the opposite effects on HCT116 cells.S LC38A1 is overexpressed in colorectal cancer,which suggests that it is associated with tumour progression.These results encourage the exploration of SLC38A1 as a target for intervention in colorectal cancer.

Objective To describe the epidemiological characteristics of profession related long-standing behavior during preconception and progestation,and to probe the relationship between prolonged standing jobs and the common pregnancy related complications among pregnant women,in Ma' anshan city,Anhui province.Methods In this cohort study,subjects who had their first antenatal examination at Ma' anshan Maternal and Child Care Centers were recruited under informed consent,from October 2008 to October 2010.All the information were collected through questionnaires in the first,second and third trimesters respectively.Three questionnaires were filled in by subjects under the guidance of healthcare takers.Results In the study,the 754 percentile of prolonged-standing times were 4.0 h/d and 3.0 h/d respectively in preconception and progestation.The characteristics of pregnant women with low social/economic status,prone to be involved in stand-long occupation.Results in logistic regression analysis,prolonged-standing jobs during preconception was the risk factor of pregnancy-induced hypertension and severe anemia.The adjusted odds ratios were 2.05 (95％CI:1.26-3.31) and 1.38 (95％CI:1.03-1.85) respectively.Conclusion Prolonged standing jobs appeared to be common occupational exposure to and risks of both pregnant woman and their fetus.Exposure to these kinds of jobs during preconception could increase the risk of pregnancy-induced hypertension and severe anemia.In order to promote maternal health programs,all the related occupational risk factors should be valued and avoided during preconception and pregnancy.

OBJECTIVETo investigate if the duration from poisoning to treatment (no treatment period) is related to the prognosis of patients with severe acute organophosphorus pesticide poisoning (SAOPP).

METHODSOne hundred and seventy-four patients with the pre-hospital systematic treatment served as the treatment group while 160 patients going to the hospital by themselves without treatment or rejecting gastrolavage served as the control group. Patients in both groups were treated by gastrolavage, pralidoxime chloride, atropine and other expectant treatment. The duration of no treatment period, death, and severe complication were observed. The time of disappearance of symptoms, the recovery time of acetyl cholinesterase (AChE), atropinization time, atropine dosage, pralidoxime chloride dosage, naloxone dosage, hospitalization days and other targets were also observed.

RESULTSThe duration of no treatment period in treatment group [(1.2 +/- 0.3) h] was significantly shorter than that in control group [(2.8 +/- 0.5) h, (P < 0.01)]. The mortality rate in treatment group was 6.32% while that in control group 22.5% (P < 0.01). The incidence of respiratory failure, heart injury, brain injury, atropine poisoning, intermediate syndrome, liver injury in treatment group (12.64%, 5.75%, 8.62%, 1.72%, 4.60%, 5.17% respectively) were lower than those in control group (25.63%, 13.75%, 17.50%, 6.25%, 7.50%, 9.38% respectively, P < 0.05 or P < 0.01). The time of symptoms disappearance, the recovery time of AChE, atropinization time, atropine dosage, pralidoxime chloride dosage, naloxone dosage, hospitalization days in treatment group were significantly superior to those in control group (P < 0.05 or P < 0.01).

CONCLUSIONThe pre-hospital systematic treatment can improve the prognosis of the patients with SAOPP, which is worth popularizing and using.

To further study the characteristics of changes on the molecular level of rice mutants induced in space environment, we analyzed proteins in leaves and seeds of four rice mutants (two high-tillering and two low-tillering) in the 8(th) and 9(th) generations after a 15-day spaceflight, and compared with their ground controls by two-dimentional polyacrylamide gel electrophoresis and reverse phase liquid chromatography (RPLC). In addition, the albumin, globulin, prolamine, glutelin, and amylose of the mutant seeds were analyzed by RPLC and ultra-violet spectrometry. The results showed that the low-abundance proteins of leaves in the peak tillering stage are more likely to be induced compared with their corresponding controls. The albumin, globulin, and prolamine of the mutant seeds revealed changes when compared with their controls, and the characteristics of changes in different mutants were stably inherited in the 8(th) and 9(th) generations, suggesting that they can be used as bio markers to identity the mutants induced by spaceflight. Moreover, two proteins (SSP9111 and SSP6302) were found to be expressed with high intensity (two-fold change) in different mutants, which were both correlated with photosystem according to mass spectrometry and database searching.
