Objective To improve clinicians'understanding of nephrotic syndrome and myasthenia gravis as adverse events of penicillamine(D-PA).Methods Two patients were reported to develope adverse reaction after taking D-PA.The related literature were reviewed.Result The first case was a systemic sclero- sis(SSc)patient treated with D-PA who developed nephrotic syndrome and blepharoptosis.The second case was a rheumatoid arthritis patient treated with D-PA who developed dysphagia and drinking bucking.The clinical symptoms were improved after disconting D-PA.Their conditions were stable up to now.Conclusion D-PA is used widely for various of autoimmune diseases.Clinicians should pay attention to these special and rare adverse effects.

Objective To detect the expressions of nerve growth factor (NGF) and its receptors tyrosine kinase A (TrkA) as well as p75 neurotrophin receptor (p75NTR) in the lesions of lichen planus.Methods Biopsy specimens were collected from the lesions of 32 patients with lichen planus and normal skin of 12 healthy human controls and subjected to paraffin embedding.Immunohistochemical avidin-biotin complex (ABC) method was used to detect the expressions of NGF,TrkA and p75NTR.Results NGF and TrkA,which were located in the cytoplasm of keratinocytes,were strongly or moderately expressed in the lesional skin specimens,but absent or weakly expressed in the normal skin specimens (both P < 0.01).No significant differences were observed in the expression of p75NTR between the lesional and normal skin specimens,or in the expressions of NGF,TrkA or p75NTR among specimens from patients in different age groups,patients of different gender or lesions at different sites (all P > 0.05).There was a positive correlation between the expression of NGF and TrkA in the lesions of lichen planus (R2 =0.535,P < 0.01).Conclusion NGF may play a certain role in the development of lichen planus via its highaffinity receptor TrkA.

Objective To explore whether obese adolescents had neurochemical abnormalities in frontal lobe and hippocampus.Methods Anthropometric indicators were measured in all participants.Proton magnetic resonance spectroscopy(1H-MRS)were performed in 9 obese adolescents and 9 non-obese children as controls.Spectral peaks of N-acetylaspartate(NAA),creatine(Cr),choline(Cho)of 2 cortexes were measured and their ratios were computed and compared.Results Values of NAA and Cho in frontal lobe in obese group were significantly lo-wer than those of controls.There was no significant difference of Cr,NAA/Cr,Cho/Cr in frontal lobe and hippocampus between 2 groups.Conclusion The reduced NAA and Cho on 1H-MRS suggests that amount of neural nerve and myelination of white matter may be harmed in frontal lobe of obese adolescents.
6.Impact of endocrine disrupting chemicals on semen quality.
National Journal of Andrology 2011;17(10):943-946
Endocrine disrupting chemicals (EDCs) are natural or man-made agents that interfere in some way with human or animal normal endocrine function, and even influence the endocrine function of their offspring. There are many kinds of EDCs, which are widely present in soil, water, and even food. This review elaborates the impact of EDCs on human and animal semen quality from the viewpoint of epidemiology and biology by focusing on pesticides, plasticizers and detergents.

A new flavonoid glycoside, (-)-2S-8-methyl-5,7,4'-trihydroxyflavanone-7-O-β-D-glucopyranoside (1), along with five known ones, quercetin-3-O-(2"-galloyl)-α-L-arabinoside (2), kaempferol-3-O-α-L-arabinoside (3), guaijaverin (4), trifolin (5) and hyperin (6), was isolated from the leaves of Eucalyptus robusta. Their structures with absolute configurations were elucidated by NMR, HR-ESI-MS, CD spectra data and physicochemical methods. In addition, 2-6 were isolated from E. robusta for the first time.

ObjectiveTo explore the causes for descending of the serum testosterone (T) in middle-aged and elderly men with metabolic syndrome (MS).MethodsFifty-six male patients aged between 45 and 83 years old were investigated.Blood pressure,height and weight were measured,and body mass index (BMI) was calculated.Biochemical indice in fasting state [ fasting blood sugar (FBG),total cholesterol (TC),triglycerides (TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol (HDL-C) ],fasting insulin (FIN),and the level of serum testosterone) were detected.An insulin resistance index (IR) was calculated using homeostasis model assessment (HOMA).Participants were divided into the MS group and the non-MS group according to CDS diagnostic standard.The relationships between the level of serum Testosterone and each index were analyzed.ResultsThe level of serum Testosterone was significantly lower in the MS group than that in the non-MS group [ (9.97 ± 3.87 ) nmol/L vs.( 13.73 ± 3.93 ) nmol/L,t =3.337,P < 0.01 ].Multiple regression analysis showed that the level of serum testooterone was negatively correlated with age,waist circumference and HOMA-IR ( regression coefficients:- 0.214,- 0.329,- 0.317; standardized regression coefficients:- 0.730,- 0.597,- 0.313 ; t =- 5.833,- 4.681,- 2.686 respctively; P < 0.01 ).ConclusionThe level of serum testosterone descends in middle-aged and elderly men with MS.The level of serum testosterone is closely related to age,waist circumference and insulin resistance

Objective To explore the impact of intermittent androgen deprivation therapy on prostate volume and lower urinary tract symptoms (LUTS) in patients with prostate cancer combined with prostatic hyperplasia (BPH),and to evaluate the clinical effect of intermittent androgen deprivation therapy as compared with conventional drug in patients with BPH.Methods Patients with prostate cancer (n=57) and BPH (n=83) were respectively treated with intermittent androgen deprivation therapy and finasteride combined with alpha-receptor antagonist.Prostate volume,international prostate symptom score (IPSS),quality of life index (QOL) and maximum urinary flow rate (Qmax) in patients were observed before and 1,3,6 and 12 months after treatment.Results The improvements in prostate volume,IPSS,QOL and Qmax were higher in prostate cancer patients treated with intermittent androgen deprivation therapy than in BPH patients treated with finasteride combined with alpha-receptor antagonist (P < 0.05).Conclusions Intermittent androgen deprivation therapy can significantly reduce prostate volume and improve LUTS in patients with prostate cancer,and has a better clinical effect than finasteride combined with alpha-receptor antagonist treatment.

Objective To evaluate the clinical significance of sinus heart rate turbulence(HRT)and the heart rate variability(HRV)in the patients with essential hypertension(EH).Methods HRV and HRT examination were carried out in sixty patients with EH.A subgroup of patients receive metoprolol+nifedipine(n=26)or nife- dipine alone(n=34)were investigated seperately to evaluate the effect of ?-blocker on the HRV and HRT.Fifty healthy persons were served as control.In the HRT determination,turbulence onset(TO)was defined as sinus heart rate acceleration,after ventrieular mature beat while turbulence slope(TS)as sinus heart rate deceleration slope after ventricular premsture beat.Normal value of TO was2.5 ms/RR period. SDNN,RMSSD,LF/HF in HRV were analysed from 24 hours ambulatory electrocardiography(before and after 1 month medication).Results ① In hypertensive group,52 patients showed positive TO(86.6%),48 patients pos- itive TS(80.0%)and 46 patients TO+TS(76.7%),compared with hypertension group only 2(4%)positive TO and 3(6%)positive TS in the healthy control.Forty-two cases SDNN(70.0%),41 cases RMSSD(68.3%)and 38 cases LF/HF(63.3 %)were positive in hypertensive group,while only 1(2 %)SDNN,1(2 %)RMSSD and 3(6 %) LF/HF in control. ② Metoprolol didn't change the positive percentage of parameters in HRT but parameters showing Heart rate variablity in HRV was decreased significantly found between TO,TS and TO+TS.Conclusion HRT and HRV is two indices for determination the dysfunction of autonomic nervous system in hypertension.?-re ceptor blocker inhibit sympathic activity,miligate the decreasing of HRV,but the bipbase accelerative and decelera- tive phenomena of HRT didn't change,HRT seems to be a more sensitive index for monitoring of autonomic sysfunc tion in hypertension.
