Objective To investigate the effect of endoplasmic reticulum stress in hyperlipidemia rats with acute pancreatitis(AP).Methods Forty-eight SD rats were divided into AP group(n=18,in- duced by injection of 40?tg/kg caerulein in normal rats twice with 2 hrs interval),normal control(n=6), byperlipidemia group(n=6,fed with a high-fat diet for 8 weeks)and hyperlipidemia AP group(n=18,in- duced by injection of 40?g/kg caerulein in hyperlipidemia rats twice with 2 hrs interval).The rats were sacrificed at 9,12,24 hrs(6 of each),respectively.Serum level of amylase was tested and the pathologi- cal changes of the pancreatic tissues were observed.The index of pancreatic apoptosis was assessed by TUNEL method.The expression of GRP78/Bip(glucose regulated protein)protein was determined by immunochemistry,the endoplasmic reticulum stress related molecules of XBP-1 splicing(X box binding protein),CHOP/GADD153(C/EBP-homologous protein or growth arrest and DNA-damage-inducible gene 153),caspase-12 were analyzed by RT-PCR.The dynamic expressions of GRP78/Bip and caspase- 12 were determine,d by Western blot.Results Artier 8 weeks of fat diet in hyperlipidemia rats,the ser- um levels of triglyceride[(0.99?0.38)mmol/L]and cholesterol[(3.17?0.18)mmol/L] were signifi- cantly increased(P

Objcctive To investigate the predictive value of the 40 Hz auditory steady-state response (ASSR) in patients with the malignant process of middle cerebral artery territory infarction.Methods The40 Hz ASSR and brainstem auditory evoked potential (BAEP) were performed within 72 hours after patients with middle cerebral artery terrtory infarction admitted in the neuro-intensive care unite (NICU).At the same time,the National Institutes of Health Stroke Scale (NIHSS) scores were assessed.Multivariable logistic regression analysis was used to deterrmine the influencing factors of the malignant process.The relevant indicators of the malignant process were analyzed by the receiver operating characteristic(ROC) curve in order to clear the predictive value of 40 Hz ASSR in the malignant process of middle cerebral artery territory infarction.Results A total of 104 patients with supratentorial middle cerebral artery territory infarction were included.They were divided into the malignant process group (n=59) or the non-malignant process group (n=45).There were significant differences in the baseline NIHSS scores (17.25 ± 7.23 vs.20.40 ± 8.09; t =- 2.055,P =0.043),infarct volume (105.85 ± 73.37 mm3 us.179.15 ± 144.38 mm3; t =-3.011,P =0.004),leukocyte count ([ 10.26 ±3.14] × 109/L vs.[ 13.45 ±5.42] × 109/L; t =-3.336,P =0.001),40 Hz ASSR (Z =-3.237,P =0.001),and short-latency somatosensory evoked potentials (Z =-3.130,P =0.002) grade between the malignant process group and the non-malignant process group.Multivariate logistic regression analysis showed that the40 Hz ASSR (odds ratio [OR] 3.347,95％ confidence interval [CI] 1.630 -6.872; P=0.014),infarct volume (OR 1.006,95％ CI 1.001 - 1.012,P=0.003),and leukocyte count (OR 1.277,95％ CI 1.074 - 1.402; P =0.001) were the independent predictors in patients with the malignant process of middle cerebral artery territory infarction.When the 40 Hz ASSR was grade 3,the sensitivity and specificity of predicting malignant process were 39.5％ and 94.4％.Conclusions The 40 Hz ASSR has an important predictive value in patients with the malignant process of middle cerebral artery territory infarction.

One of the challenges in andrology nowadays is the diagnosis and treatment of external genital abnormalities and defects along with the consequent voiding, sexual, and reproductive dysfunctions, for which no guidelines are yet available. Hitherto, surgical repair and reconstruction are efficient for these diseases. The key to these operations is to individualize surgical strategies according to the specific local lesion and dysfunction, usually involving flap and graft techniques. This article presents our experience in the surgical treatment of penile and scrotal abnormalities and defects with urological and andrological techniques and microsurgical strategies, focusing on the external repair and functional reconstruction. Satisfactory treatment outcomes pivot on a precise evaluation of the disease, a rational design of surgical procedures, and an earnest communication with the patient. Some cases are rather complicated and challenging, usually with complications, and therefore deserve further researches for more effective treatment strategies in clinical practice.

Objective To investigate neuroprotective effect of AM-36 on secondary brain injury following traumatic brain injury(TBI)in rats.Methods A total of 38 male Sprague-Dawley rats were divided into an experimental group,a control group and a sham operation group,then sustained to moder- ate TBI.AM-36(0.1 ml/100 g)was administered intraperitoneally in the experimental group and isoton- ic saline solution was administered intraperitoneally in the control and the sham operation groups at 30 mi- nutes,24 and 48 hours after TBI,respectively.The brain water content was determined at 24 hours after TBI.Rats were sacrificed by decapitation at 24 hours or one week after TBI for observing histological changes in peripheral cortex,thalamus and hippocampus by means of Hematoxylin and Eosin staining and Fluoro-Jade(F-J)staining.Results The brain water content of bilateral hemispheres 24 hours after TBI in the experimental group was significantly decreased,compared to that of the control group.Histo- logical examination revealed less degenerating neurons(F-J positive neurons)in the cortex,thalamus, CAI and CA3 of the hippocampus in AM-36 treated rats 24 hours and one week after injury(P＜0.05). Conclusion Systemic administration of AM-36 at the early stage after TBI can decrease brain water content and exert neuroprotective effect on TBI.F-J staining can be used for histopathologic quantitation of neuronal damage,for it can accurately exhibit pathologic changes following TBI induced by fluid per- cussion.

ObjectiveTo explore the relationship between the status of vitamin A and the level of AntiHBs in infants.Methods One hundred and ninty eight infants met the criteria were recruited into an investigation through local vaccination service.Two milliter venous blood was drawn from each studied child,and the infants' feeding information of successive 72 hours was collected through the 24-hour dietary recall method and 2-day diet records method.The nutrients intakes were analyzed with a NCCW software for calculation.The concentration of serum vitamin A and Anti-HBs was analyzed by HPLC and ECLIA,respectively.The logarithm of anti-HBs concentrations was compared among sub-clinical vitamin A deficiency (87 cases ),suspicious subclinical vitamin A deficient group (51 cases )and normal group (60 cases )and the relationship between the logarithm of anti-HBs concentrations and vitamin A were analyzed.ResultsThere were only 19.7％ of children whose average daily intake of vitamin A reached the 80％ of recommended nutrient intakes(RNI).The incidence rate of vitamin A malnutrition was 67.2％.The serum Anti-HBs GMC was 402.8 U/L The positive rate was 98.0％.There were significant differences on Anti-HBs Ig GMC between Sub-clinical vitamin A deficiency (SVAD) group,suspicious SVAD group and normal group( F =15.88,P ＜ 0.001 ).The correlation coefficient between the level of serum vitamin A and Anti-HBs lg GMC was 0.441 ( P =0.01 ).ConclusionThe results show that the level of serum vitamin A may have influence on the maintenance of an effective anti-HBs level against hepatitis B virus.

OBJECTIVETo investigate the prevalence of malignant tumor and its influencing factor among rubber workers in Hainan Province of China, and to study the high incidence of cancer and type of work.

METHODSA retrospective cohort study on registered workers over 1 working age among partial rubber factories in Hainan Province in the period from 2005 to 2010.

RESULTThere was a remarkable difference in the incidence between nature exposed rubber group and non-exposed group (χ(2) = 52.13,P < 0.01). Occupational exposure induced a high risk in malignant tumors (OR = 2.47, P < 0.05). The incidence of tumor may be associated with occupational exposure: the longer occupational exposure time, the higher was the incidence of tumor (χ(2) = 11.40, P < 0.05).

CONCLUSIONSThe occupational exposure in rubber workers can induce a high incidence of malignant tumor.

OBJECTIVETo investigate the malignancy incidence among rubber manufacture and preliminary processing industrial workers in Hainan Province of China.

METHODSA retrospective survey was conducted on 9 farms in Hainan covering workers who got malignant tumor between January 1, 2005 and October 31, 2010.

RESULTOn average there were 10 320 workers worked on the 9 farms each year. Among them, 167 cases of malignancy were found. The morbidity was 279.01 every a hundred thousand and standardized morbidity was 159.03 every a hundred thousand; In comparison, we also investigated 14228 non-rubber-industry-related workers. 94 malignancy cases were found. The morbidity was 113.91 every a hundred thousand and standardized morbidity was 64.93 every a hundred thousand. The difference was statistically significant (P<0.01) meaning that rubber industrial workers in Hainan Province had a higher possibility of getting malignancy. Top 5 types of cancer found in this study were lung cancer (17.96%), liver cancer (17.36%), stomach cancer (13.17%), rectal cancer and nasopharyngeal carcinoma. 116 cases of these five types of cancer took up 69.45% of the total.

CONCLUSIONSRubber industrial workers in Hainan have a higher morbidity of malignancy than other local industries. But it is similar to other areas in China.

OBJECTIVETo investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.

METHODSFrom December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.

RESULTSA total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.

CONCLUSIONNetwork education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.
