Locoweeds are presently defined as those species of the genera Oxytropis and Astragalus (family Leguminosae) that specifically contain the key toxic constituent,swainsonine.After ingesting locoweeds,livestock can develop poisoning disease characterized by chronic dysfunction of the nervous system,which causes severe economic losses to the pastoral areas.In addition,swainsonine has attracted a great attention from toxicology and medicine fields,due to its dual role of toxicity and pharmacological activity.This review not only summarizes the latest research progress of toxicity and its poisoning mechanism,pharmacological activity,source,and biosynthesis pathway of swainsonine,but also speculates the possible regulatory enzymes involved in the synthesis pathway.Moreover,the future research on swainsonine is also looked ahead,which provide references for the prevention and treatment of locoism.

BACKGROUND:No studies currently focus on the measurement of daily water loss under certain physical activity level continuously and precisely.
OBJECTIVE:To provide evidence for daily water requirement in Chinese young men based on the measurement of the daily water loss in Chinese young men under moderate physical activity.
METHODS:Twenty male subjects were enroled, and 23-hour whole-body sweat loss and urine output were measured using high-precision body weighting scale in whole-room indirect calorimeter. The results were converted to daily (24-hour) water requirement to determine the daily water requirement. Daily whole-body sweat loss per unit body weight, daily whole-body sweat loss per unit fat free mass and daily whole-body sweat loss per unit surface area were calculated.
RESULTS AND CONCLUSION:In Chinese young men, daily water loss was (3 339.7±509.9) g, daily urine output was (1 982.9±449.5) g and daily whole-body sweat loss was (1 356.7±215.6) g. There was a linear correlation between water intake and water loss (r=0.616,P < 0.05). Daily whole-body sweat loss per unit body weight was (21.0±3.6) g/kg, daily whole-body sweat loss per unit fat free mass was (25.8±3.9) g/kg and daily whole-body sweat loss per unit surface area was (799.4±129.4) g/m2. Daily water requirement of Chinese young men under moderate physical activity is approximately 3 340g, and moreover, water loss increases with the increase of water intake.

Aiming at the problem that it is difficult to accurately recognize the position and the figure of P wave in the ECGs easily influenced by the diversified interference,a P wave detection algorithm based on approximating functions in the optimum region is proposed in this paper. In the algorithm we use a conic to approach the P wave by means of the least square method in every region, which is shifted in local range. Then we find the optimum approach region of P wave by comparing the approximating error. Finally, we attain the characteristic points of P wave by using the approximating functions to approach P wave in the optimum region. The performance of the algorithm tested using the records of the MIT-BIH database is effective and accurate.

OBJECTIVE: To investigate the single nucleotide polymorphism of NOS1AP gene with sudden unexpected death (SUD) during daily activities. METHODS: The heart blood samples were collected from 60 SUD cases in normal daily activities as SUD group and the peripheral blood samples from 80 random unrelated cases as control group. The genome DNAs from all cases were isolated and the gene sequences were analyzed from specific primers of some SNP (rs10494366, rs10918859, rs12143842, rs12742393, rs3751284, and rs348624) of NOS1AP. The allele frequency and genotype frequency were calculated and the difference in these SNP between SUD group and control group were analyzed. RESULTS: The allele frequency and genotype frequency of rs3751284 which located at the sixth exon domain had significant statistical differences between the two groups (P<0.05). The minor allele frequency of rs3751284 was 0.325 in SUD group and was 0.475 in control group. CONCLUSION rs3751284 might be a susceptibility locus for SUD.

OBJECTIVE: To understand the correlation of enterovirus 71 (EV71), P-selectin glycoprotein ligand-1 (PSGL-1), and scavenger receptor B2 (SCARB2) and to explore the possible pathway and mechanism of EV71 infection by observing the expression of EV71, PSGL-1 and SCARB2 in tissues of infants with brain stem encephalitis. METHODS: The organs and tissues of infants with EV71-VP1 positivity in their brain stems were chosen. Expression and distribution of EV71-VP1, PSGL-1, and SCARB2 were detected and compared by immunohistochemistry. RESULTS: Strong staining of EV71 -VP1 was observed in the neuron, glial cells, the inflammatory cells of perivascular cuffing, parietal cells of the gastric fundus gland while alveolar macrophages, intestinal gland epithelium cells, mucosa lymphoid nodule and lymphocyte of palatine tonsil showed moderate staining and weak staining were displayed in mesenteric lymph nodes and lymphocyte of spleen. PSGL-1 expression was detected in parietal cells of the gastric fundus gland, tonsillar crypt squamous epithelium, alveolar macrophages and leukocytes in each tissue. SCARB2 expression was observed in all the above tissues except the intestines and spleen. CONCLUSION The distribution of EV71 correlates with SCARB2 expression. SCARB2 plays an important role in virus infection and replication. Stomach may be an important site for EV71 replication.

OBJECTIVETo analyze the clinical characteristics of protracted bacterial bronchitis (PBB) in children.

METHODThe clinical data of patients seen from October, 2010 to March, 2014 in Department of Respiratory Diseases of our hospital were retrospectively analyzed. Inclusion criteria were over 4 weeks cough, receiving fiberoptic bronchoscopy, positive bacterial culture and (or) the increased percentage of neutral granulocytes in bronchoalveolar lavage fluid (BALF).

RESULTTwenty eight patients were involved, 26 were male (93%) and two were female (7%). The median age of patients was 8.5 months. The median duration of cough was four weeks. The average length of hospital stay was (8.3 ± 3.9)days. The main clinical feature was wet cough in 28 cases, wet cough with wheezing was seen in 21 cases. The wet cough phase distribution was irregular in 21 cases. The crackles with wheeze (in 21 cases) was main signs of PBB. The percentage of CD3⁻ CD16⁺ 56⁺ cells increased in peripheral blood. The fiberoptic bronchoscopic manifestations of PBB were luminal mucosal edema. Eleven patients also had airway malacia. The neutrophil median in BALF was 0.2. The positive rate of bacterial culture of BALF was 36%. The main bacteria were Streptococcus pneumoniae (50%) and Haemophilus influenzae (30%). The main treatment for PBB patients included amoxycillin/clavulanate potassium and second-generation cephalosporins. The average duration of treatment was (17.3 ± 3.2)days, the prognosis was good.

CONCLUSIONPBB is common in male infants. Persistent wet cough with wheezing was the main characteristic of PBB. PBB is commonly accompanied by immune dysfunction and airway malacia, and the pathogens were Streptococcus pneumoniae and Haemophilus influenzae.

OBJECTIVETo investigate the correlation of the testis volume and reproductive hormone level with the results of testicular sperm aspiration (TESA) in non-obstructive azoospermia (NOA) patients, and to explore the cut-off value of the testis volume and reproductive hormone level in predicting the results of TESA so as to provide reliable information for the diagnosis and treatment of NOA.

METHODSWe enlisted 121 NOA patients in this study, divided them into a sperm group and a non-sperm group based on the results of TESA, and measured their testis volumes and reproductive hormone levels.

RESULTSThe left testis volume, the right testis volume, and the levels of prolactin (PRL), follicle-stimulating hormone (FSH), luteinising hormone (LH), estradiol (E2) and total testosterone (T) in the non-sperm and sperm groups were (7.07 +/- 1.06) ml vs (11.75 +/- 1.38) ml, (7.37 +/- 1.37) ml vs (11.70 +/- 1.98) ml, (12.43 +/- 11.69) ng/ml vs (9.60 +/- 4.55) ng/ml, (15.77 +/- 10.84) mIU/ml vs (8.01 +/- 7.43) mIU/ml, (6.12 +/- 2.92) mIU/ml vs (8.11 +/- 20.11) mIU/ml, (119.36 +/- 43.52) pmol/L vs (141.12 +/- 48.33) pmol/L, and (11.43 +/- 4.05) nmol/L vs (12.46 +/- 4.60) nmol/L, respectively. The mean levels of serum FSH and PRL were significantly higher in the non-sperm than in the sperm group. Although the mean testis volume of the former was less than that of the latter, there were no significant differences between the two groups, and nor were any significant differences in age and the levels of E2 and T. The cut-off value of the testis volume was 9 ml, with sensitivity of 93.8%/89.6% (left/right) and specificity of 100%/94.3% (left/right). The area under curve (AUC) of the left testis volume was 0.984 and that of the right was 0.961, indicating a high diagnostic accuracy. The cut-off value of the serum FSH level was 8.18 mIU/ml, with a sensitivity of 71.2% and a specificity of 75.0%. The AUC of the FSH level was 0.743, suggestive of a moderate diagnostic accuracy.

CONCLUSIONThe testis volume and FSH level are important for predicting the TESA results of NOA patients, and the former has even a higher diagnostic accuracy than the latter.

OBJECTIVETesticular mixed nonseminomatous germ cell cancer (TMNGCC) is rarely reported. This study aimed to explore the clinical symptoms, pathological characteristics and treatment methods of TMNGCC.

METHODSWe analyzed the clinical data of 1 case of TMNGCC, observed its pathological characteristics under the light microscope by histology, cytochemistry, immunohistochemistry and immune marking, and investigated the clinical features of such tumors by reviewing the relevant literature.

RESULTSThe patient presented with a chief complaint of painless testicular swelling for 3 years. Histopathological examinations revealed a tumor of papillary, fissural or adenoid structure, with large polygonal or columnar cells with one or more irregular vesicular nuclei, the nuclear membrane clear, the cytoplasm eosinophilic or basophilic, and the interstitium infiltrated by a few lymphocytes. Here are the immunohistochemical results: CD117 -, CK8-18 + +, CD30 + +, CK + + +, vimentin -, PLAP +/-, P53 +, AFP + and EMA + +. The tumor was pathologically diagnosed as teratogenic embryonic testicular cancer, and treated by radical surgery, followed by adjuvant chemotherapy according to the treatment of TMNGCC. One-year follow-up found the patient to be alive.

CONCLUSIONTMNGCC is a rare malignant tumor, mostly with unobvious clinical symptoms. Its diagnosis primarily depends on physical examination, ultrasonography, CT, and measurement of serum tumor markers; its confirmation necessitates pathological examination, and its first-choice treatment is surgical resection.

OBJECTIVETo investigate the changes in the range of motion (ROM) and stress of the intervertebral disc and facet joint of the adjacent segments following anterior cervical corpectomy and fusion (ACCF) and anterior cervical discectomy and fusion (ACDF) using finite element analysis.

METHODSA three-dimensional finite element model of the lower cervical vertebrae was constructed and validated by comparing the ROM of the finite element model against the published data. After the validation of successful modeling, finite element models of ACDF and ACCF were constructed. The ROM and the stress of the intervertebral disc and facet joint of the adjacent segments were compared between the intact lower cervical vertebrae and the cervical vertebrae after ACDF and ACCF.

RESULTSThe ROM of the finite element model was consistent with the published data. The total ROM and the ROM of the fusion segments with ACDF and ACCF were significantly decreased compared with the intact cervical vertebrae. In the adjacent segments following ACDF and ACCF, the ROM the adjacent segments and the stress peak of the intervertebral disc and facet joint all increased obviously compared with those of intact cervical vertebrae.

CONCLUSIONAfter fusion surgeries, the total ROM of the cervical vertebrae decreases and the ROM of the adjacent segment increases. The stress peak of the intervertebral disc and facet joint of the adjacent segments also increases to significantly alter the physiological characteristics of the intact cervical vertebrae.
