Objective To determine the effect of obesity on prostate specific antigen (PSA) in men with benign prostatic hyperplasia (BPH) and develop a PSA-related parameter that can eliminate the effect of obesity. Methods We reviewed the clinical data of 706 patients with BPH. Two PSA-related parameters, namely PSA mass (total circulating PSA protein) and PSA mass ratio (total circulation PSA protein per prostate volume), were calculated for all the patients and the association of BMI with PSA, PSA mass, and PSA mass ratio was assessed. Results A higher BMI was significantly associated with a greater plasma volume and prostate volume (P<0.05). Linear regression analysis revealed a greater adjusted R2 of BMI versus plasma volume than of BMI PSA (0.569 vs 0.027). PSA was positively associated with the prostate volume and negatively with BMI and plasma volume (P<0.05). PSA mass was positively associated with prostate volume (P<0.05) but was not associated with BMI or plasma volume (P>0.05). PSA mass ratio was not associated with prostate volume (P>0.05) but negatively associated with BMI and plasma volume. Plasma volume and prostate volume, PSA, and PSA mass ratio (P<0.05), but not PSA mass (P>0.05), differed significantly among normal-weight, overweight, and obese patients. Conclusion A higher BMI is associated with a greater plasma volume in BPH patients. In obese patients with BPH, a lower PSA concentration may result from hemodilution caused by a greater plasma volume, and PSA mass can eliminate the effect of obesity on PSA.

Objective To explore the early laboratory indicators for risk of intravenous immunoglobin-resistant Kawasaki diseases. Methods The clinical data were retrospectively analyzed in 881 Kawasaki disease patients (group A: 26 cases of intravenous immunoglobin-resistant; group B: 855 cases of intravenous immunoglobin-sensitive) from July 1, 2015 to June 30, 2016. After 1:3 matching with age and sex, the regression model for each of variables including sex, age, fever days, temperature, red blood cell count (RBC), white blood cell count (WBC), neutrophil (N), lymphocyte (L), platelet count (PLT) and C reactive protein (CRP), was constructed by conditional logistic regression analysis. Results Compared with group B, group A had significantly lower RBC count and higher PLT (P<0.05). Logistic regression analysis showed that, with the age, the regression model was Y=-2.87+0.01×PLT (PLT OR=1.01, 95% CI: 1.00~1.01, P<0.01); with the sex, Y=-32.98+0.44×WBC+0.28× N+0.01×PLT (WBC OR=1.55, 95% CI: 1.17~2.05, P<0.01; N% OR=1.32, 95% CI: 1.04~1.68, P<0.05; PLT OR=1.01, 95% CI 1.00~1.01, P<0.01). Conclusion In case that abnormally high levels of PLT exist in confirmed Kawasaki disease, it should be aware of possibility of the intravenous immunoglobin-resistant Kawasaki disease.

Objective:To explore the establishment and assessment of the depression model of adult SD rats induced by early maternal infant separation stress combined with adult chronic unpredictable mild stress(CUMS), and to observe the behavior and synaptic protein expression of SD rats.Methods:Twenty-four male rats were randomly divided into three groups: control group (CON group), chronic unpredictable stress group (CUMS group), maternal infant separation combined with chronic unpredictable stress group (MS + CUMS group). The depression model of rats in cums group was established by CUMS, and the depression model of rats in MS + CUMS group was established by maternal infant separation + CUMS. The depression model was evaluated by body mass and appearance observation, sugar water preference experiment, open field test and forced swimming test.Synapse-associated proteins (PSD-95 and synaptophysin (Syn)) of the hippocampus were assayed using Western blot. Syn protein expression was measured by immunohistochemistry.Results:After modeling, compared with CON group, the rats in CUMS group and MS + CUMS group had significantly lower body mass((126.43±3.88) g, (91.04±3.85) g, (69.89±6.67) g; t=5.03, 8.03, both P<0.01), significantly lower sugar water preference((94.21±0.56)%, (79.30±1.13)%, (72.73±1.82)%; t=8.24, 11.87, both P<0.01) and significantly increased immobility time((3.50±0.84)s, (13.59±2.40)s, (15.70±2.97)s; t=3.16, 3.82, both P<0.01). Among them, the body mass and sugar water preference of MS + CUMS group were lower than those of CUMS group ( t=3.00, 3.63; both P<0.01). (2)The center time of the rats in MS+ CUMS group markedly reduced compared with that of CON group((21.41±4.65) s, (8.96±2.37) s; t=2.66, P<0.05). (3)In the immunohistochemistry experiment, compared with the CON group, the percentage of Syn positive area in hippocampus of rats in CUMS group and MS+ CUMS group decreased significantly ((24.42±0.76)%, (14.00±0.95)%, (10.38±1.38)%; t=6.93, 9.33, P<0.01). (4)The results of Western blot showed that compared with CON group, both the expression of PSD-95 ((1.18±0.02), (0.74±0.06), (0.52±0.05), t=6.29, 9.31; both P<0.05) and Syn ((1.12±0.08), (0.95±0.06), (0.90±0.07); t=3.10, 4.04; both P<0.05) in hippocampus of rats in CUMS group and MS+ CUMS group were significantly decreased.And compared with the CUMS group, the expression of PSD-95 in MS+ CUMS group was lower( t=0.93, P<0.05). Conclusion:The method of MS combined with CUMS can effectively induce depression like behavior and decrease the expression of synaptic plasticity related protein of hippocampus in rats.

Objective:To investigate the efficacy of treatment of bromhidrosis by cutting off the apocrine glands under direct vision combined with micro electrocoagulation.Methods:From January 2017 to December 2017, 25 patients (50 sides) with axillary osmidrosis admitted to the First People’s Hospital of Yuhang District were treated with direct vision cutting and micro electrocoagulation to destroy the apocrine sweat glands, including 13 males and 12 females, aged 14-38 years, with an average age of 23 years. According to Young-Jin Park′s criteria for judging axillary osmidrosis, 21 cases were classified as grade 3 and 4 cases as grade 2. After tumescent anesthesia, the subcutaneous apocrine sweat glands, fat and hair follicles were cut off under direct vision. The subdermal vascular network was preserved, and the basement was destroyed one by one by using high-frequency electrocoagulation mode. After the operation, the evaluation was conducted according to the criteria for judging axillary osmidrosis formulated by Young-Jin Park.Results:The symptoms of axillary osmidrosis reached the standard of cure in 24 patients after operation, 1 case failed to reach the cure standard. Among the patients who reached the standard, there were 2 cases of necrosis of the skin flap and 1 case of hematoma after operation unilaterally, which were given actively dressing change, secondary debridement, suturing and hematoma removal, The follow-up period was 6 months to 1 year. During the follow-up period, 24 cases were cured, including 21 cases of grade one and 3 cases of grade zero. The treatment effect was stable.Conclusions:The treatment of axillary osmidrosis by cutting off the apocrine sweat glands under direct vision combined with micro electrocoagulation, exposing the apocrine sweat glands as much as possible, effectively removing the apocrine sweat glands and hair follicles, and reducing the recurrence rate of axillary osmidrosis. It is a simple, safe and effective treatment technology for axillary osmidrosis.

Objective To investigate the effects of long-term exposure to three new types of light emitting diode (LED) sources on the behavior, learning, and memory of rats. Methods A total of 160 specific pathogen-free SD rats were divided into eight groups as followed, trichromatic fluorescent lamps color temperature control group, violet-chip full-spectrum white LED group, blue-chip white LED group, and blue-chip full-spectrum white LED group based on the light sources types, with color temperature of 4 000 K and 6 500 K groups in each group using the 4×2 factorial design. There were 20 rats in each group, with half of the rats were males and half females. Rats were exposed to artificial lighting, and the illumination was set at 750 lx. The rats in each group were exposed to different lighting environments for 12 hours per day for 24 weeks. The open-field and step-down tests were conducted in rats after 24 weeks exposure, followed by sacrifice of rats and measurement of organ coefficients. Differences in body weight, organ coefficients, and neurobehavioral indexes of rats in different groups were compared. Results The spleen coefficient of female rats decreased in blue-chip white LED of 6 500 K color temperature group, and the liver coefficient of male rats decreased in the violet-chip full-spectrum white LED of 4 000 K color temperature, blue-chip full-spectrum white LED of 4 000 K color temperature, and blue-chip full-spectrum white LED of 6 500 K color temperature groups, compared with the same-sex rats in trichromatic fluorescent lamps with same-color temperature control group (all P<0.05). The result of different types of light sources compared in the open-field test showed that the index of total distance and movement speed of female rats in the blue-chip full-spectrum white LED group were lower than those in the other three groups, and the time cost to the central area was longer than that in the blue-chip white LED group and the violet-chip full-spectrum white LED group (all P<0.05). The total distance and movement speed of male rats in the blue-chip full-spectrum white LED group were longer or higher than those in the violet-chip full-spectrum white LED group (all P<0.05). Based on the comparison of color temperature, the time and total distance of male rats in 6 500 K color temperature group were lower than that in the 4 000 K color temperature group (both P<0.05). In the step-down test, both male and female rats in the blue-chip full-spectrum white LED group made more errors compared with other three groups with the same gender (all P<0.05). Conclusion Based on the experimental conditions of this study, the blue-chip full-spectrum white light LED affects behavior, learning and memory of the rats, and trichromatic fluorescent lamp has the lowest effect on neurobehavior. The color temperature also affects behavior of the rats, and high color temperature has higher risk.
