Objective To investigate the clinical and pathological features of prostate cancer with low level of serum prostate-specific antigen (PSA) in elderly patients.Methods Data of 328 patients with prostate cancer were retrospectively analyzed.Clinical and pathological data of 4 prostate cancer patients with low serum PSA level were analyzed.Potential risk factors and diagnostic methods of prostate cancer with low serum PSA level were discussed based on the clinical data combined with literatures.Results Mean age of the 4 patients was 71.3 years.Mean PSA value on admission was 1.96 μg/L.2 patients had abnormal digital anal examination results.2 patients were pathologically diagnosed as adenocarcinoma after puncture,among which 1 had duct adenocarcinoma,and the other 2 patients were pathologically diagnosed as neuroendocrine carcinoma after puncture.2 patients with neuroendocrine carcinoma of prostate were treated with endocrine therapy,and the other 2 patients were treated with radical prostatectomy plus auxiliary endocrine therapy.Conclusions Prostate cancer with low serum PSA level has an insidious onset,which is prone to miss the diagnosis.It should be paid sufficient attention for the diagnosis,and monitoring of prostate cancer is independent on PSA.Prostate cancer with low serum PSA level should be diagnosed in combination with some basic examinations such as serum free prostate specific antigen,prostate specific antigen density and digital rectal examination,et al.

Objective To establish a HPLC method to detect the propofol concentration of plasma in children undergoing cardiopulmonary bypass. Methods RP-HPLC with fluorescence detector was used in the study. Plasma samples were precipitated by the thymol-methanol solution, and centrifugated. 20?l of supernatant fluid was injected for analysis and separated by Dikma Diamonsil C18 column. The mobile phase was composed of acetonitril:water =56:44(V/V), flo rate was 1.0ml/min. Fluorescence detective wave lengths were ?ex= 276nm, ?em=312nm. HPLC machine was Agilent1100 series. Main column was Diamonsil C18(150?4.6nm,5um),guard column was Phenomenex Security(4mm?3mm). Results There was a good linear relationship within the range of 0.02～8.0mg/L(r=0.9993, n =9),the limit of detection was 5?g/L,average recovery was 96.99%,intra RSD(relative standard deviation )was between0.810% and 5.73%,inter RSD was between 0.932% and 7.337%. Conclusions The method is sensitive, simple, rapid, good linear relationship and precise. The experiment can be used for determination of propofol concentration in child undergoing cardiopulmonary bypass.

Objective To investigate the clinical value of surem eystatin C and urinary transforming growth factorβ1(TGF-β1)in patients with severe eclampsism.Methods Serum cystatin C and urinary transforming growth factorβ1 were examined in 35 severe eclampsism women(experiment group,n=35)and normal late pregnant women(control group,n=35).Results The levels of serum cystatin C and urinary transforming growth factorβ1 were both significantly increased in experiment group than those in control group(both P<0.01).The serum level of cystatin C was positively correlative with urinary TGF-β1 level in experiment group(r=0.581,P<0.05).Conclusion The detection of serum cystatin C and urinary transforming growth factorβ1 is useful to assess renal function lesion in patients with severe eclampsism,which contributes to the diagnosis and treatment of severe eclampsism.

Objective To study the effects of γ-aminobutyric acid ( GABA) and sertraline on the CABAA(α) receptor and GABAB receptor of hippocampus neuron in rats of depression induced by acute stress. Methods The cognitive function of male SD (Sprague-Dawley) rats was screened through Y-maze. Then rats were randomly divided into five groups. Except control group,rats were injected intraperitoneally with double-distilled, GABA,sertraline or GABA + sertraline respectively. They were exposed to the forced-swimming stress test,which was to make acute stress model of depression. The space memory function in the maze was measured. Then the number of GABA-like immunoreactive neurons in hippocampus CA1 ,CA3 ,DG areas of rats were investigated with immunohistochemist. Results Compared with the model group,the immobility time in the forced-swimming test and the latency in the maze could be reduced significantly after pretreatment with GABA and sertraline (P < 0.01). The positive cell populations of CA1 ,CA3 region and DG gate region in the model group were significantly reduced compared with the control group (P<0.01). GABA could only improve the positive cell populations of GABAB receptor in CA3 region (P<0.01). In the sertraline group,the positive cell populations in hippocampus were increased obviously more than it in model group(P<0.01). The positive cell populations of hippocampus in the GABA + sertraline group in CA1 ( (82.83±8.72),(78.08±5.67)),in CA3((92.83±9.35),(76.00±3.97)),in the gate of DG( (35.00 ±1.41) ,(33.33±4.36)) increased significantly to the other groups (P< 0.05 or 0.01). Conclusion Ectogenic GABA could improve the sertraline' s effects of antagonizing acute depression effectively and the space memory function,and its mechanism may be involved in strengthening the expression of GABAA(α) receptor and GABAB receptor in hippocampus.

Objective To analyze clinical and bacteriological features and therapeutic methods of erysipelas following breast cancer surgery in 12 hospitalized patients. Methods Clinical data on 12 patients with erysipelas following breast cancer surgery were collected from 3 third-grade class-A hospitals in Ningbo. A retrospective study was carried out. Results Of the 12 patients, 8 were treated with modified radical mastectomy and axillary lymph node dissection, 3 with radical mastectomy and axillary lymph node dissection, and 1 with mammectomy only. All of the 12 patients suffered from postoperative lymphedema on the affected side. Erysipelas mostly occurred within 1 - 18 years (mean, 8.0 years)after breast cancer surgery, and on the same side of surgery in all the patients except 2 with multi-site infection. Specifically speaking, erysipelas was located in the upper extremity in 8 patients, in the chest wall in 1 patient, in the lower extremity in 1 patient. Blood culture was performed for 5 patients, of whom, 2 showed positive results, including 1 infected with Streptococcus equisimilis and 1 with Klebsiella pneumonia. Six patients were treated with penicillins, but the primary treatment failed in 2 patients. After replacement of antibiotics, all the 12 patients experienced an improvement of the condition and were discharged from hospital. Conclusions Patients who suffer from lymphedema after breast cancer surgery are prone to erysipelas of the upper limbs and chest wall. Caution should be taken against gram-negative bacterial infections in these pateints. The treatment of lymphedema should be taken into account besides antibiotic therapy.

Objective To evaluate the efficacy of narrow-band ultraviolet B (NB-UVB) for the treatment of early-stage mycosis fungoides (MF).Methods A retrospective study was performed on 98 patients with early-stage MF treated with NB-UVB from January 2003 to December 2013.The rate of and time to recurrence of MF were assessed,and long-term side effects were evaluated in these patients.Results Among 52 patients achieving complete remission,the median number of sessions of NB-UVB radiation was 30 (range,18-87),the median cumulative radiation dose was 24.16 J/cm2 (range,9.11-108.86 J/cm2),and the median follow-up duration was 41 months (range,11-90 months).Relapse occurred in 14 (26.9％) patients with the median time to recurrence being 8.2 months (range,3-60 months).The patients suffering from relapse achieved complete remission after treatment with NB-UVB again.Adverse reactions mainly included skin erythema and itching at the early stage of radiation,as well as temporary pigmentation after radiation.Cutaneous carcinoma occurred in none of these patients during 11-90 months of follow-up.Conclusions NB-UVB phototherapy appeared to be effective for the treatment of early-stage MF,and no cutaneous carcinoma occurred in these patients during the follow-up.Although MF may relapse in some cases,repeated NB-UVB phototherapy is still effective.

Objective To analyze the blood pressure,heart rate,the US national institutes of health stroke scale(NIHSS) score,Glasgow coma scale(GCS) score for cerebral infarction patients with cerebral hemorrhage after recombinant human tissue-type plasminogen activator (rt-PA) therapy.Methods From April 2011 to April 2013,48 cases with cerebral infarction after intravenous rt-PA thrombolysis were collected.These cases were divided into two groups:the first group (32 cases):without cerebral hemorrhage after thrombolysis; the second group (16 cases):with cerebral hemorrhage after thrombolysis.The systolic blood pressure,diastolic blood pressure,heart rote,NIHSS score and GCS score were compared between the two groups before and after thrombolysis.Results After thrombolysis,the systolic and diastolic blood pressure were significantly increased in cerebral hemorrhage cases compared with before thrombolysis and patients without cerebral hemorrhage.After thrombolysis,the NIHSS score was significantly reduced in the cases without cerebral hemorrhage compared with that before thrombolysis,while the NIHSS score was significantly higher in the cases with cerebral hemorrhage compared with that before thrombolysis.After thrombolysis,the heart rate and GCS score showed no significant difference between the patients with and without cerebral hemorrhage.Conclusions The rising of systolic blood pressure,diastolic blood pressure and NIHSS score helps us determine the early cerebral hemorrhage after thrombolysis in cerebral infarction patients.
