ABSTRACT
Objective To know the residues of 13 veterinary drug residues in chicken and eggs foods in some areas in Xinjiang. Methods A total of 170 chicken and egg samples were randomly selected from supermarkets and farmers' markets in seven cities in Xinjiang. Eleven quinolone antibiotics, two tetracycline antibiotics, ribavirin and metronidazole were examined for veterinary drug residues using liquid chromatography tandem mass spectrometry (LC-MS/MS) . Results The overall detection rate of veterinary drug residues in eggs and chicken were 20%（18/90）and11.25%（9/80）. The overall over-standard rate were 18.89%（17/90）and 0（0/80）. Veterinary drug residues in chicken are heavier than eggs. Veterinary drugs were detected and over-standarded in all seven cities in Xinjiang monitored. Conclusion The veterinary drug contamination in chicken and eggs in Xinjiang is relatively serious. It is recommended to strengthen the standardization of production and supervision to ensure food safety.

ABSTRACT
Objective:To observe the effect of early temperature control on the prognosis of brain injury patients after severe carbon monoxide poisoning (COP).Methods:A total of 277 patients hospitalized with severe COP were randomly divided into a fever group ( n=78), a normal temperature group ( n=113) and a mild hypothermia group ( n=86). All were given hyperbaric oxygen therapy and any necessary supportive treatment. The mild hypothermia group were kept in a room at 34 to 35℃. Evaluation was with the Glasgow Coma Scale (GCS), version II of the Acute Physiology and Chronic Health Evaluation (APACHE), the Hasegawa dementia scale (HDS) and the mini mental state examination (MMSE). The incidence of delayed encephalopathy (DEACMP) and mortality were compared among the three groups. The bispectral index (BIS) and neuron-specific enolase (NSE) levels were correlated with DEACMP. Results:After the treatments, improvement was observed in multiple indexes of all three groups compared with before the treatment. Compared with the fever group, the average GCS of the mild hypothermia group was significantly higher on the 2nd, 4th, 8th and 31st day after the intervention. It was significantly higher than the normal temperature group′s averages on the 4th, 8th and 31st day. The average APACHE scores of the normal temperature and the mild hypothermia groups were significantly lower than the fever group′s average, with that of the mild hypothermia group significantly lower than that of the normal group. The average HDS scores of the normal temperature and mild hypothermia groups were significantly higher than the fever group′s average, with that of the mild hypothermia group significantly higher than that of the normal group. The average MMSE score of the mild hypothermia group was significantly improved after 7 days, one month and three months of treatment. That of the normal group showed significant improvement after one and three months, but the mild hypothermia group′s averages were superior. Compared with the fever group, the average BIS score of the mild hypothermia group was significantly better after one, three and seven days, and one month. This was true for the normal group beyond three days after the intervention. The average NSE concentration of the normal group after 7 days and one month was significantly lower than that of the fever group. For the mild hypothermia group this was true after only 3 days. Compared with the other two groups, the average coma time, incidence of DEACMP and nervous system injury were significantly lower in the hypothermia group. The average GCS, BIS and NSE values were closely related to the occurrence of DEACMP.Conclusions:Early temperature control can significantly reduce the severity of brain injury after COP and reduce the incidence of neurological sequelae. Early dynamic detection of GCS, NSE concentration and BIS is of great significance for predicting the incidence of DEACMP.
ABSTRACT
<p><b>OBJECTIVE</b>To survey the knowledge and behaviors of antibiotic use for children among parents in Ningbo and to explore the influencing factors.</p><p><b>METHODS</b>One kindergarten and one primary school were randomly selected in Yinzhou and Beilun District of Ningbo using stratified random cluster sampling method, respectively. A survey on the knowledge and behaviors of antibiotics use for children was conducted with a self-designed questionnaire among parents of children aged 2 to 14 years in the sampled kindergarten and school.</p><p><b>RESULTS</b>The scores of antibiotic use knowledge were 0-4 in 36.6%(1028/2806) of parents. In the past month, 56.6%(556/983) of parents self-medicated their children, including 20.3%(113/556) medicated with antibiotics. In the past year, 48.5%(1361/2806) of parents stored antibiotics for children at home. Multivariate logistic regression analysis showed that mother, and parents with city residence, higher education level, higher household income, medical background, male children and younger children had higher antibiotic use knowledge scores(<0.05 or <0.01); parents with city residence, higher education level and medical background were more likely to store antibiotics at home (all <0.01); parents with city residence and those store antibiotics at home were more likely to self-medicate their children with antibiotics (<0.05 or <0.01).</p><p><b>CONCLUSIONS</b>sPoor knowledge and massive antibiotic missuse for children among parents are of great concern in Ningbo. Tailored health education programs are needed to improve the knowledge and behaviors of rational antibiotic use among parents and reduce storage of antibiotics at home.</p>

Objective To explore the neuroprotective effect of targeted regulation Nrf2 gene on rats with brain injury caused by acute severe carbon monoxide ( CO ) poisoning. Methods A total of 180 healthy adult SD rats were divided into 4 groups at random:normal control group( NC group) ,CO poisoning group(CO group),lentivirus group(LV group) and Nrf2 gene therapy group(Nrf2 group),and 45 rats in each group. An acute CO toxic rat model was established by inhalation in a hyperbaric oxygen tank. The lentivirus group was directly injected with lentivirus dilution (4×106 TU/μl) into striatum with a microsy-ringe guided by a stereotactic apparatus,and the Nrf2 gene therapy group was administrated the same dose of recombinant Nrf2 gene lentivirus dilution,while rats in the normal control group and the CO poisoning group were received the same amount of normal saline. Five rats were taken and decapitated at day 1,day 7 and week 2 from each group,respectively. The mitochondrial membrane potential (MMP) of neurons in brain tis-sue was detected by JC-1 method,and the expressions of Nrf2 and GCLC proteins were observed by immuno-histochemistry and Western Blot. Results Compared with the NC group (cortex:(75. 3±6. 8);hippocam-pus:(76. 4±7. 1);striatum:(73. 8±7. 3)) at the same time point,the MMPs of neurons in CO group (cor-tex:(34. 5±6. 7);hippocampus:(30. 3±5. 6);striatum:(41. 5±6. 1) and LV group (cortex:(36. 8±6. 2);hippocampus:(30. 8±6. 0);striatum:(42. 7±6. 3)) were significantly decreased,and the difference was sig-nificant(P<0. 05). However,there was no significant difference between the CO poisoning group and the lentivirus group (P>0. 05). A small amount of Nrf2 protein (0. 22±0. 05) and GCLC protein (0. 24±0. 04) were expressed in the brain tissue of normal control rats. The expressions of Nrf2 protein (0. 31±0. 06,0. 31 ±0. 05) and GCLC protein (0. 30±0. 04,0. 31±0. 07) in CO group and LV group were slightly increased (P<0. 05). Similarly,there was no significant difference between the CO poisoning group and the lentivirus group (P>0. 05). The MMPs value of nerve cells in the Nrf2 group (cortex:(53. 3±5. 3);hippocampus:(56. 9±6. 1);striatum:(60. 6±6. 0)) also decreased,but it was significantly higher than that in the CO group and the LV group at the same time point (P<0. 05) . The expression of Nrf2 in brain tissue was signifi-cantly increased (0. 59±0. 05),and there was significant difference between CO group and LV group at the same time point (P<0. 05);GCLC protein increased slightly (0. 37±0. 06),but there was no statistical difference compared with CO poisoning group and lentivirus group (P>0. 05). Conclusion CO poisoning could induce oxidative stress and damage mitochondrial function of nerve cells. The active state of targeted regulation Nrf2 could significantly enhance the antioxidant capacity of rats and positively protect rats against brain injury induced by acute severe CO poisoning.
ABSTRACT
Objective To investigate the expression of a proliferation-inducing ligand (APRIL) in urothelial carcinoma tissue and its clinical significance. Methods We investigated the expression of APRIL mR-NA in urothelial carcinoma tissue of 33 patients in urothelial carcinoma in Cangzhou Central Hospital from July 2013 to March 2015, Among of them, 23 cases of adjacent pericancerous tissues were detected by qRT-PCR. Immunohistochemistry and western blot were used to detect the APRIL protein expression level in urothelial carci-noma tissue and adjacent pericancerous tissues. We analyzed the relationship between APRIL expression and clinical pathology in patients with urothelial carcinoma by statistical methods. Results The qRT-PCR revealed that the expression of APRIL in urothelial carcinoma tissue was significantly higher than that in the adjacent peri-cancerous tissues (P 0.05). Conclusion The APRIL is a high abnormal expression in urothelial carcinoma tissues , and maybe related to the occurrence and development of urothelial carcinoma.
ABSTRACT
Objective To explore the influence of carbamazepine on the plasma homocysteine (Hcy),folic acid and vitamin B12 levels in the treatment of epilepsy.Methods The clinical medical history and medication com-pliance of 80 epilepsy patients were retrospectively analyzed.40 cases treated with carbamazepine were set as group A,another 40 cases without taking antiepileptic drug therapy were set as group B.And 40 cases in the same period in hospital physical examination were selected as control group.The levels of blood Hcy,folate and vitamin B12 were detected by using the fluorescent quantitative method,the electrochemical luminescence immunoassay,and the differ-ences of three groups of the levels were compared.Results The Hcy level of group A was significantly higher than the control group and group B(F =7.16,P =0.00),and the folic acid level of group A was significantly lower than the control group and group B(F =9.67,P =0.00).The Vit B12 concentration of group A was lower than the control group and group B,but among the three groups,the difference was not statistically significant(F =1.05,P =0.15). Loss of appetite and body weight decreased in 4 cases,2 cases of dizziness,fatigue,but symptoms were mild,did not affect the findings.Control in 13 cases,12 cases were markedly effective,effective in 8 cases,ineffective in 7 cases,the total effective rate was 82.5%.Conclusion Carbamazepine treatment can cause epilepsy patients blood Hcy level rise,and folic acid level drop,has no significant effects on the Vit B12 concentration,so in patients with epilepsy should pay attention to monitor blood Hcy and folic acid level during the treatment,in order to avoid adverse events such as thrombosis and influence the prognosis.
ABSTRACT
Objective:To detect the expression of Shank1 protein in renal cell carcinoma (RCC), to investigate its difference between the tumor and carcinoma adjacent tissue, and to analyze its correlation with RCC clinicopathological characteristics and prognosis. Methods:The renal carcinoma and carcinoma adjacent tissues of 120 patients were selected from Cangzhou Central Hospital and Ji'nan Central Hospital from May 2008 to December 2014. The expression level of Shank1 was determined by immunohistochemistry and Western blot. Statistical analysis was performed to determine the relationship between the expression of Shank1 and the clinicopathological features of RCC patients. Results:Results of immunohistochemistry showed that the expression level of Shank1 in renal cancer tissue was significantly higher than that in carcinoma adjacent tissue, and the difference was statistically significant (P<0.05). Western blot results showed that the expression level of Shank1 protein in renal cancer tissue was also significantly higher than in carcinoma adjacent tissue. Correlation analysis found that the high expression level of Shank1 in renal cancer tissue was not significantly related to gender, age, tumor size, and TNM stage, but was significantly associated with the histological differentiation of RCC (P<0.05). Conclusion:Shank1 is abnormal y expressed in RCC renal cancer tissues and is correlated with the histological differentiation of RCC.
ABSTRACT
Objective To study the clinical manifestation,diagnosis and treatment of the renal myxofibromata.Methods Combined with reviewing the relevant literature,we retrospectively analyzed the clinical data of a case of renal myxofibromata.A 47-year-old female patient was found left renal cystic lesion by ultrasound 8 months before admission.CT showed a 4 cm cystic and solid lesions in the lower pole of left kidney,which was similar to the results of ultrasound.The enhanced abdominal CT and dynamic contrast-enhanced ultrasound showed that the lesions could be enhanced slowly with uneven density.The patient underwent left kidney exploration under the general anaesthesia.During operation,a round solid mass about 5 cm in diameter can been seen in the low part of renal sinus,which was a bit hard.The mass was close with surrounding tissue.Then,the left kidney was excised.Results The surface of the mass was full and smooth with pale yellow luster.In the HE section,the tumor was composed with fibroma like cell,which demonstrated the inhomogeneous size,shape and irregular organization.The nucleus showed the spindle shape,with rare mitosis phase.Large quantity of mucus and vascular tissue could be observed in the tumor.Few fibroblast cells could also be found in the section.The pathological result was myxofibromata (immature) with malignant tendency.No special treatment was given after surgery.Recurrence was not recorded within 6 months following-up.Conclusions Commonly,the myxofibromata is a kind of benign tumor.Only a few can result in the malignant transformation and distant metastasis.Primary renal myxofibromata is extremely rare.The preoperative imagine manifestation is difficult to provide the accurate diagnosis.Pathologic result is the gold standard in diagnosing this disease.Actively surgical treatment and regular following-up after surgery should be considered.
ABSTRACT
Objective To study incidence of deep vein thrombosis (DVT) in the acute phase and follow-up period after stroke, and to investigate risk factors of DVT. Methods This was a prospective study at multi-centers. Ultrasonography was used for detecting DVT on both lower extremities in all patients at 10-14 days after the onset of stroke. All patients were followed up for 6 months after discharge. The incidence of DVT was examined in the acute phase and in the follow-up period of stroke. A variety of patient and treatment related factors were compared between stroke patients with DVT and without DVT to identify DVT risk factors. Results The incidence of DVT in the acute period of stroke was 4. 49%. Among DVT patients, 51.6% patients presented clinical DVT symptoms. By multiple factors logistic regression analysis,age ( ≥70 years, OR = 1.63, 95% CI 1.08-2. 84), bedridden( OR =4. 85, 95% CI 2.65-9. 68 ), wells score ≥ 2 ( OR = 3.96, 95% CI 1.86-7. 86 ), lower limbs NIHSS score ≥ 3 ( OR = 4. 56, 95% CI 2. 07-8. 85 ), high D-dimer ( OR = 3.45, 95% CI 2. 01-8. 52 ), low BI scores ( OR = 2. 98, 95% CI 1.52-6. 47 ), rehabilitation therapy ( OR = 1.82, 95% CI 1.22-3.43 ) and anticoagulant therapy ( OR =1.91,95% CI 1. 34-4. 92 ) were independent risk factors of DVT in the acute phase of stroke. Among them, the rehabilitation therapy and anticoagulant therapy were protective factors. The incidence of DVT in the follow-up periods was 1. 51%. Age ( ≥ 70 years, OR = 1.82, 95% CI 1.21-3.98 ), bedridden after discharge( OR = 5. 12, 95% CI 2. 82-11.32), lower limbs NIHSS score ≥3 ( OR = 4. 25, 95% CI 2. 11-7. 87), low BI score( OR = 2. 18, 95% CI 1.18-6.23 )at the time of discharge and DVT in acute period (OR =3.81,95%CI 1.87-7.48)were independent risk factors of DVT in the follow-up period of stroke.Conclusions Stroke patients, particularly old-aged stroke patients, are a high-risk group of developing DVT. 48.4% DVT patients had no clinical DVT symptoms but were diagnosed only by ultrasonography.There are multiple independent risk factors of DVT after stroke. It is necessary to monitor and prevent DVT in the stroke patients with the risk factors. The rehabilitation therapy and anticoagulant therapy may decrease incidence of DVT.
