Objective To compare the gastric mucosa damage induced by celecoxib and conventional NSAIDs——indomethacin. Methods NSAIDs induced gastric mucosal damage model in rats was obtained by pouring indomethacin, celecoxib respectively (n=8); After gastric damage induced by means of 100% ethanol, celecoxib were administered by gastric gavage (n=8). Gastric mucosal 6-keto-PGF 1? ,TXB 2 level and lesion index (LI) were measured. Morphological changes of gastric mucosa were assessed under light and scanning electronic microscopy. Results Indomethacin caused obvious gastric damage (LI:13.38?2.06) and a marked reduction of 6-keto-PGF 1? ,TXB 2 level was observed (P

NSAIDs users have higher number of ulcers ( P =0 002), fewer dyspeptic symptoms ( P =0 000) and shorter hospital stay( P =0 017).

0.05).NSAIDs users were older than nonusers by a mean of 11 years, more likely to have a history of UGIG (P=0.002)and cardiac vessel disease(P=0.00 0).NSAIDs users have more number of ulcer or erosion(P=0.001)and fewer hospital stay(P=0.011). Conclusion Proper measures should be employed to decrease NSAIDs induced GI complications.

Objective To study the relationships between androgen receptor (AR)expression and the clinicopathological features and prognosis of young patients (age≤35 years)with early-onset breast cancer in Xinjiang.Methods One hundred and forty-five young patients (age≤35 years)with invasive breast cancer who underwent surgery in Affiliated Cancer Hospital of of Xinjiang Medical University from January 201 0 to December 201 2 were collected.The expressions of AR in 1 45 patiens with early-onset breast cancer were detec-ted by immunohistochemical method.The relationships between AR expression and the clinicopathological fea-tures and prognosis of patients with early-onset breast cancer were retrospective analysed.Results The posi-tive rate of AR expression of patients with early-onset breast cancer in Xinjiang was 69.0% (1 00 /1 45).Single factor analysis showed that AR expression was related with neurovascular invasion (χ2 =5.309,P =0.021 ) and lymph node metastasis (χ2 =6.073,P =0.01 4),but it was not related with ethnicity (χ2 =0.097,P =0.755),age (χ2 =0.045,P =0.831 ),feeding history (χ2 =0.066,P =0.797),family history of cancer (P =0.556),histological grade (P =0.469),tumor size (χ2 =1 .006,P =0.605)and clinical stage (χ2 =4.381 ,P =0.223).The median follow-up time was 47 months.There was no significant difference between AR expression and disease-free survival of patients with early-onset breast cancer (χ2 =1 .972,P =0.1 60). Conclusion Early-onset breast cancer patients with AR positive are more likely to appear lymph node metasta-sis and neurovascular invasion than the patients with AR negative,which has certain guidance means for the treatment of early-onset breast cancer with lymph node metastasis positive.

Objective To assess the efficacy of clinical intervention of early swallowing syndrome on neonates. Methods Eighty-six cases of normal newborns were enrolled in the study, including 44 cases of natural delivery,32 cases of cesarean section,8 cases of premature infant. The cases started vomitting before feeding the milk, became more severe after feeding the milk. once the pathological factors were excluded, the cases were treated with breastfeeding, warm water enema, massaging the lower abdomen, 1% sodium bicarbonate solution to the gastric lavage. Results A variety of clinical interventions on the control of neonatal swallowing syndrome results are obvious. Conclusions Early detection early intervention can prevent complications occurring.

The present paper reports that the fenfluramine(FA), amphetamine(AP) and methamphetamine(MA) were extracted from the blood by the solid phase microextraction(SPME). The drugs were extracted for 15 min under the condition of 70℃ by a polydimethylsiloxane fiber. d5-methamphetamine(IS) was used as an internal standard. GC/MS was used for analysis with the injection method of derivatization on column. The ions at m/z 268(FA), m/z 240(AP), m/z 254(MA) and m/z 258(IS) in the selected ion minitoring chromatograms were selected for quantitation. Each compound was detectable at least 0 01～0 03 ?g/g. By determination of fenfluramine in poisoning blood, it is proved that this method would be demonstrated to be simple and accurate.

Objective Through the analysis of misdiagnosis left renal vein entrapment syndrome,to improve the understanding and reduce the misdiagnosis of this disease.Methods 82 cases of left renal vein compression syn-drome were diagnosed with ultrasound,65 cases were misdiagnosed.Clinical data of these 65 patients were analyzed.Results In 82 cases,only 11 doctors from renal department of internal medicine,pediatrics,department of urology wrote application for it.Among the 65 misdiagnosed cases,30 cases of male,female 35 cases.The age ranged from 6 to 37 years old,the average age was 16.1 years.The misdiagnosis duration ranged from 2 months to 42 months,the median time was 7 months.43 cases of low back pain or backache,urinary tract irritation in 5 cases,60 cases of abnor-mal urinalysis:a simple urinary protein in 15 cases,21 cases of simple hematuria,proteinuria,hematuria 24 cases. 31 cases were misdiagnosed as chronic glomerulonephritis,occult nephritis(asymptomatic proteinuria and hematuria syndrome)in 11 cases,acute nephritis comprehensive sign in 9 cases,7 cases of lumbar muscle strain,urinary tract infection in 4 cases,1 case of urinary tract stones,pelvic inflammatory disease in 2 cases.In the 16 cases complicated with glomerular nephritis,were treated as the glomerular nephritis before (11 cases of chronic nephritis,5 cases of asymptomatic proteinuria and hematuria syndrome).12 cases of abnormal urine fluctuation,after a delay of 3 -16 months referral doctor was diagnosed with left renal vein entrapment syndrome.Conclusion The disease has no char-acteristic clinical manifestations,and most clinicians were short in understanding of the disease,so the misdiagnosis rate is high.The clinicians should improve the understanding of the disease,in order to reduce the misdiagnosis rate.

Objective To observe the influence of swimming training on the expression of nerve growth factor (NGF) and neurotrophins-3 (NT-3) in rats with cerebral infarction,and to explore the underlying neuroprotection mechanism of exercise training on cerebral infarction.Methods Forty-five healthy male Sprague-Dawley rats were randomly divided into a sham-operation group,a control group and a training group,with 15 rats in each group.Each group was further divided into a 3-day,7-day and 14-day subgroups,which amounts to 9 groups.To establish animal model of cerebral ischemia-reperfusion in rats,the intraluminal thread method was applied to cause left middle cerebral artery occlusion (MCAO) for 2 h before reperfusion.The rats of the training group were given swimming training for 10 min,once daily,while those of the sham-operation and control groups were not given any training.Neurological deficits were assessed using Bederson scores.The expression of NGF mRNA and NT-3 mRNA in the ischemiareperfusion pallium was examined using reverse transcription-polymerase chain reaction (RT-PCR).Results The rats of the sham-operation group showed no neurological deficits.At the same time points,the average Bederson scores of the training group were significantly lower than the control group,but significantly higher than the sham group.Moreover,the 14 d training group had the lowest Bederson score (1.20 ±0.45),compared to the value 3 and 7 days after modeling.The expression of NGF mRNA and NT-3 mRNA of ischemic cerebral cortex in the training group was significantly improved when compared to the sham-operation group or the control group.On day 14,the expression of the NGF mRNA (0.66 ± 0.07),and the NT-3 mRNA (0.79 ± 0.06),were significantly higher than those on day 3 and 7.Conclusions Swimming training could increase the expressions of NGF mRNA and NT-3 mRNA in the ischemic cerebral cortex.It might be one of the key mechanisms that exercise training could promote the recovery of damaged neurological function in rats with cerebral infarction.

OBJECTIVE:To explore the factors,general rule and characteristics of adverse drug reactions(ADR)for references of safe and rational clinical medication.METHOD:A total of 412 ADR reports were collected and statistically analyzed in respect of age and sex of patients,route of administration,ADR degree,drug category,ADR-involving organs and clinical manifestations etc.RESULTS:ADR-involving drugs totaled 412 kinds,of which anti-infective agents occupied the first place,followed by Chinese patent medicines.274 ADR cases(66.50%)were induced by intravenous route.ADR occurred systemically and were characterized predominantly by allergic reactions of skin and its appendants,followed by damage of nervous system.70 were new but common ADR cases,while 2 were new severe cases.CONCLUSION:It is necessary to strengthen ADR monitoring and publicizing of ADR-related knowledge to guide the clinical rational use of drugs and reduce the repetitive occurrence of ADR.
