Objective To explore the relationship of zearalenone (ZEA) and precocious puberty in girls.Methods The peripheral serums from 71 cases of precocious puberty girls and 50 cases of healthy girls were collected respectively and concentrations of ZEA were detected by high performance liquid chromatography.Bone age,body mass index (BMI),volume of uterus and ovaries,concentrations of estradiol (E2),luteinizing hormone (LH) and folliclestimulating hormone (FSH) were detected,and the residence of each subject was recorded as well.Results (1) In 71 patients,52 patients were diagnosed as idiopathic central precocious puberty,others were diagnosed as premature thelarche.(2) In 71 patients,serum ZEA was detected from 51 patients,and undetected in 20 patients.(3)Concentration of ZEA in precocious puberty girls [(318 ±34) ng/L]was significantly increased than that in healthy girls [(143 ± 35) ng/L,P =0.002],but no distinct difference existed between ICPP group and PT group(P =0.326).(4)Compared with uterus volume of ZEA in the undetected patients (1.975 ±0.150) cm3,the uterus volume of ZEA detected patients (2.972 ±0.180) cm3,which was significantly enlarged,there was significant difference (P =0.01) ; Percentage of overweight girls in ZEA detected patients (31.4％,16/51 cases) was lower than which in ZEA undetected patients (65.0％,13/20 cases,P =0.01) ; Although there was no statistical differences in the breast diameter,bone age,value of E2,LH and FSH between ZEA detected patients and undetected patients (all P ＞ 0.05),but the increased tendency in ZEA detected patients existed.(5) ZEA in serum was detected in 53.3％ (16/30 cases) patients living in the cities,and the rate was obviously lower than 82.9％ of the patients (34/41 cases) living in the countryside,there was significant difference (P =0.007).Conclusions ZEA is correlated with precocious puberty in girls.ZEA pollution might be one of reasons for precocious puberty occurrence.

Objective To investigate the position sense in chronic non-specific low back pain (CNLBP) patients, and the correlation to pain and endurance of psoas muscles. Methods From January, 2014 to May, 2015, 30 patients with CNLBP and other 30 healthy subjects were measured spine flexion and extension position sense absolute error (AE) and psoas endurance with Biodex System 3 synchronously, and the patients were self-assessed the pain in lumbar with Numerical Rating Scale (NRS). The Pearson correlation coefficient of AE to pso-as endurance and NRS was calculated. Results AE of flexion and extension was both more in the patients than in the healthy (t>1.862, P<0.05), and the psoas muscle endurance was less (t=2.307, P<0.05). AE of flexion (r=-0.71) and extension (r=-0.47) negatively correlated with the psoas muscle endurance in the patients, and positively correlated with NRS score (r=0.78 for flexion, and r=0.49 for extension). AE mildly negative correlated with the psoas muscle endurance (r=-0.38 for flexion, and r=-0.29 for extension). Conclusion Spine sensation has been impaired in CNLBP patients, and may associate with pain and psoas muscles endurance loss.

Objective: To develop a headspace gas chromatography ( HS-GC ) assay for simultaneous determination of dichloroacetic acid ( DCA ) and trichloroacetic acid ( TCA ) in urine. Methods: Urine samples (5 mL) were transferred to a 22 mL headspace bottle, added with 0.5 mL 10% sodium acetate solution , immediately sealed, and shaken evenly. The bottle was placed in the HS-GC system, and equilibrated at 90 ℃ for 60 minutes. The mixture was separated with the HP-INNOWAX chromatographic column, and the DCA and TCA concentrations were detected with the hydrogen flame detector. Results: Under the optimal experimental conditions, the correlation coefficient of DCA and TAC was both > 0.999 0 within the range of 10-500.0 μg/L, and the lowest detection limits of DCA and TAC were 2.0 and 3.5 μg/L, with the spike recovery rate of 87.40% to 101.44%, and relative standard deviations of 1.89% to 3.25%. Of the 35 urine samples sampled from occupational populations, DCA and TCA were not detected. Conclusions The establishment of the HS-GAS assay through addition of sodium acetate and optimization of the headspace conditions, has high recovery and precision, which is effective to meet the requirements for daily determination of DCA and TCA in urine samples.

Objective To clarify the protective effect of nrsodeoxycholic acid ( UDCA ) on endoplasmic reticulum stress-mediated apoptosis in pancreatic β-cell of streptozotocin ( STZ )-induced diabetic rats.Methods Rats( n =40) received a single injection STZ( 50 mg/kg) intra-peritoneally and formed a β-cell injury model.Weight-matched normal rats( the control group,n =10 ) were injected with the buffer alone.STZ-treated rats with persistent random blood glucose higher than 16.7 mmol/L for 1 week were considered as diabetic status( n=14 ),then divided randomly into STZ-induced diabetes mellitus ( DM ) group ( n =7 ) and UDCA-treated DM group ( n =7 ).UDCA (40 mg· kg- 1,d-1 ) was administered daily by intragastric intubations throughout the experimental period (30 d).During the entire experiment,blood glucose in all rats was assessed.By the end of the experiment,all rats were sacrificed with the pancreas removed and the blood sample collected immediately.Fasting insulin levels were assayed by radioimmunoassay.The morphological changes of pancreatic β-cells apoptosis were determined by TUNEL assay.RNA in pancreas was abstracted and microarray containing 89 pieces of apoptosis related genes was applied.The related gene expressions were detected by RT-PCR and Western blot.Results The concentration of blood glucose in diabetic rats was gradually decreased after UDCA treatment,but at the end of the experiment it was still higher than that in the normal control group.The treatment with UDCA raised the fasting insulin level in diabetic rats,but this concentration was significantly lower as compared to the control group.Based on TUNEL stained tissue sections,the percentage of β-cell apoptosis of UDCA-treated DM group was significantly lower than that of STZ-induced diabetic group(P＜0.05 ).Among 89 genes,42 genes up-regulated and 46 genes down-regulated in diabetic rats,some of which were ameliorated by UDCA treatment.The expressions of Caspase-3,Bax,Bip,and CHOP mRNA in pancreas of DM group were significantly up-regulated as compared with those in the control group ( P ＜ 0.05 ) ; while the expression of Bcl-2 mRNA was markedly down-regulated (P＜0.05 ).However,these parameters in the U DCA-treated animals showed a marked improvement.Conclusion Ursodeoxycholic acid seems to protect pancreatic β-cell from apoptosis in STZ-induced diabetes by attenuating the severity of endoplasmic reticulum stress.

Objective: To evaluate the false positive rate and false negative rate of the Chinese version of the 12-item General Health Questionnaire (GHQ-12) and the related factors in the epidemiological survey of mental ill-nesses in Zhejiang Province. Method: A total of 15000 subjects were randomly selected from the province-wide using multi-stage stratified cluster randomization. Analyses for this paper were made in the quality control sample,10% of the total 15000 subjects (1510 subjects) in which the Chinese version of Structured Clinical Interview for DSM-Ⅳ Axis Ⅰ Disorders (SCID) was used as a golden criterion, and a cutoff score of the GHQ-12 was set to ≥ 3 to define GHQ-12 cases. Results: Totally 1449 subjects (96.0%) completed both the GHQ-12 and the SCID. Adjusted for sampling effects, the false positive and negative rates of the GHQ-12 were respective 14.6% and7.8%. Adjusted for other considered correlates and sampling effects, the adjusted odds ratios (AORs) of GHQ-12 false positive with living in less economically developed urban areas (urban type Ⅱ), with self-reportedly poor physical health, with having ever sought help because of mental problems and with being currently married/co-habited were respective 2.23 (95% CI:1.24～4.01), 2.36(1.36～4.10), 1.53 (1.10～2.14) and 0.51 (0.30～0.86) while AORs of GHQ-12 false negative with being aged 35～49 year group and living in less econom-ically developed rural areas (rural type Ⅲ) were respective 2.59 (1.18～5.67) and 2.72 (1.21～6.14). Conclusion:Factors related to the GHQ-12 false positive and negative are different. The cutoff scores of the GHQ-12 should be used based on the characteristics of subjects during identifying or screening mental illnesses.

Background: Pre-exam anxiety syndrome is a common condition occurring in pre-exam students and directly affects their examination performance and physical state. Wrist-ankle acupuncture has significant therapeutic effects in treating mental disorders and may also relieve the symptoms of pre-exam anxiety syndrome. Objective: To assess the therapeutic effect of wrist-ankle acupuncture on pre-exam anxiety syndrome. Design, setting, participants and interventions: A total of 60 students who met the inclusion criteria of pre-exam anxiety syndrome were enrolled from a university in Shanghai and they were randomly divided into treatment group and control group. There were 30 cases in each group, and no case failed to follow-up. In the treatment group, wrist-ankle acupuncture was adopted to point upper 1 bilaterally (impression between flexor carpi ulnaris tendon and ulnar margin), and there was no requirement for Deqi (arrival of qi). In the control group, sham acupuncture was adopted. The treatment was applied 3 times totally in both groups one week before the exam, once every other day, each time with the needles retained for 30 min. Main outcome measures: The therapeutic effects were compared between two groups. Before and after 3 treatments, Sarason Test Anxiety Scale (TAS) and Expectation and Treatment Credibility Scale (ETCS) were measured and evaluated. Results: The therapeutic effect experienced by the treatment group was better than that of the control group (P<0.05). There were no statistically significant differences in TAS and ETCS before treatment between the two groups. The scores of TAS after treatment in two groups were higher than those before treatment (P<0.05, P<0.01). There were statistical differences in TAS absolute difference and TAS relative difference between the two groups and the treatment group had better results (P<0.05, P<0.01). After treatment, patients in the treatment group had higher scores in ETCS than those in the control group (P<0.05, P<0.01). No adverse reaction was reported. Conclusion: Wrist-ankle acupuncture can relieve the symptoms of pre-exam anxiety syndrome significantly, and this therapy is highly safe.

Objective To evaluate the success rate, safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) after Billroth Ⅱ gastrectomy. Methods Data of 75 patients with biliary disease after Billroth Ⅱ gastrectomy, who underwent ERCP from January 2007 to November 2009, were retrospectively analyzed. Results In 75 patients, afferent loop intubation was achieved in 69 (92%) and selective cannulation of bile duct were successful in 68 (68/69, 98. 5%). Diagnostic procedures were carried out in 3 patients, and therapeutic in 65 others, which included EST plus stone removal and ENBD in 16, ERBD in 19, EMBE in 18 and EBD plus stone removal and ENBD in 12. Afferent loop perforation occurred in 1 patient (1.3%) and was treated surgically, and 2 acute pancreatitis (2. 6%) were treated conservatively.There was no complication of bleeding. Conclusion ERCP after Billroth Ⅱ gastrectomy is safe and efficiency for biliary disease.

Objective To explore the dynamic changes of serum S100B and glial fibrillary acidic protein (GFAP) levels and their clinical significance in patients with delayed encephalopathy after acute carbon monoxide poisoning (DEACMP).Methods By means of enzyme-linked immunno-sorbent assay (ELISA),the serum S100B and GFAP levels from 33 DEACMP patients were assayed,and the condition changes were analyzed with three types of scale:the activity of daily living scale ( ADL),information-memory-concentration test (IMCT) and Hasegawa' s dementia scale(HDS).The comparison with 32 patients of acute carbon monoxide poisoning without DEACMP was also conducted.Results (1) The serum S100B( (0.60 ±0.21)ng/ml) and GFAP( (226.58 ±90.05 )ng/ml) in DEACMP group at acute stage were significantly higher than those in acute-CO-poisoning group ( (0.50 ± 0.20) ng/ml,( 183.04 ± 73.01 ) ng/ml) and those in DEACMP group at convalescent stage ( (0.51 ±0.16) ng/ml,(183.25 ±81.76)ng/ml) (all P values ＜0.05).(2)In DEACMP group,the serum S100B and GFAP at acute and convalescent stages were significantly correlated (at acute stage:r=0.466,P=0.006; at convalescent stage:r=0.365,P=0.037 ).(3)The S100B and GFAP in ineffective DEACMP patients at acute stage were significantly higher than those in the other groups ( all P values ＜ 0.05 ).(4) In DEACMP group,the ADL,HDS and IMCT scores( (45.21 ± 9.69),(8.26 ± 6.31 ),(9.91 ± 7.52) ) at acute stage were significantly different from those at convalescent stages( (33.67 ± 13.62),( 15.91 ± 10.83),( 19.06 ± 10.37 ) ) ( all P values ＜0.01 ).Conclusion There is secondary brain insult (SBI) in DEACMP; glial activation may play an important role.The S100B and GFAP levels may be associated with the prognosis of DEACMP.
