Objective To investigate the relationship between plasma cell mastitis and prolactin. Methods The relationship between the lesion area , degree of inverted nipple and prolactin level of 228 plasma cell mastitis patients were observed , as well as their prolactin level before and after treatment , to explore the factors that influence relapse. Results There was no significant statistical relationship between prolactin level and lesions area and degree of inverted nipple. Prolactin level before and after treatment were statistically different (t =2.347,P = 0.02). Menstrual status, nipple status, comorbidities, lesion area and prolactin level were considered, only prolactin level was related with disease recurrence (P = 0.038). Conclusion prolactin level could significantly reduced as the disease cured , but elevated prolactin may lead to relapse of the disease.

Objective To investigate effect of leptin on nerve function in patient with Parkinson disease .Methods 68 cases patients with PD were selected and randomly divided into two groups, according to random number table, from October 2013 to December 2014 in the hospital.34 cases in control group were treated with conventional therapy, and 34 cases in experimental group were treated with leptin, with a consecutive treatment of twelve weeks.The score of activity of daily living scale ( ADL ) and mini-mental state examination ( MMSE ) were analyzed pre and post-treatment. ResuIts After treatment, the ADL score of experimental group was significantly lower than that of control group ( P<0.05 ) , MMSE score of experimental group was significantly higher than that of control group (P<0.05).The adverse reactions in both groups were minor.ConcIusion Leptin has good curative effect in treatment of Parkinson disease, and could significantly improve the neurological function of patients, with mild adverse reactions.

Objective To explore the effects of fasudil on inhibiting vascular smooth muscle cells (VSMCs) proliferation in vitro,increasing cell apoptosis,and inhibiting the Ras-MEK 1/2-ERK 1/2 pathway.Methods Healthy male SD rats (80～100 g) were selected.VSMCs were separated by the thoracoabdominal aortic vascular membrane dissection.Cultured VSMCs were randomly divided into 5 groups:serum-free group; serum group; serum + 1 μmol/L fasudil intervention group; serum + 10 μmol/L fasudil intervention group; serum + 100 μmol/L fasudil intervention group.The proliferation and migration of VSMCs were detected by MTT method and wound healing assay.Cell cycle and apoptosis of VSMCs were examined by flow cytometric analysis.The mRNA expressions of pro-apoptotic protein (Bax) and anti-apoptotic protein(Bcl-2) were determined by RT-PCR method,and the ratio of Bax/Bcl 2 was calculated.Western blot were performed to detect the protein expressions of Ras,MEK1/2,ERK1/2 and Akt in VSMCs.Results Fasudil inhibited rat VSMCs proliferation and migration,and blocked FBS-induced progression from the G0/G1 phase to S phase in a dose-dependent manner.Fasudil inhibited the early and late apoptosis in VSMCs,increased Bax mRNA expression and inhibited Bcl 2 mRNA expression.Fasudil significantly inhibited the protein expressions of FBS-stimulated intracellular Ras,phosphorylated MEK1/2,ERK1/2 in a dosedependent manner,but did not affect the protein expression of phosphorylated Akt.Conclusions Fasudil can attenuate VMSCs proliferation by blocking Ras-MEK1/2-ERK1/2 pathway and increasing cell apoptosis.

Aim To investigate the protective effects and mechanism of aspirin against focal cerebral ischemia-reperfusion in rats. Methods Right middle cerebral artery was occluded by inserting a thread through internal carotid artery for 2 h, and then reperfused for 72 h. 60 mg?kg -1 dose of aspirin was intragastric administrated at 0 h and 6 h after reperfusion. The brain injured area, the mortality, and cerebral edema were estimated. The apoptotic cells of brain tissue were detected by terminal deoxynucleotidyl transferase mediated dUTP-biotin nick-end labeling (TUNEL) method. Bcl-2 and Bax were detected by immunohistochemical staining method. The activity of calcineurin (CaN) in brain tissue was determined by the inorganic phosphorus method. The content of adenosine 5′-triphosphate (ATP) in brain tissue was separated by capillary electrophoresis. Results By using of aspirin 60 mg?kg -1, all indications were dramatically improved. The injured area of brain [from (10.51?1.12)% to (0.94?0.08)%], the cerebral edema of occluded side [from (82.43?2.0)% to (76.29?0.77)%], and the mortality [from 28% to 0%] were dramatically reduced. In brain tissue of occluded side, 60 mg?kg -1 aspirin helped to reduce the number of apoptotic cells from (26.43?2.0) to (17.53?0.44), increase the ratio of Bcl-2/Bax from (0.61?0.05) to (1.01?0.15), inhibit the activity of CaN from (6.03?1.5) to (3.47?0.96), and improve the ATP level from (10.26?1.02) to (25.65?3.45). Conclusion The neuroprotective effects of aspirin on focal cerebral ischemia-reperfusion injury in rats for 72 h might be attributed to its effects by anti-apoptosis, increasing the ratio of Bcl-2/Bax, inhibiting the activity of CaN, and improving the energy metabolism.

Objective To evaluate the hair-removal effect of intense pulsed light (IPL) on hirsutism of spina bifida occulta. Methods 8 patients with hirsutism of spina bifida occulta were treated 3 to 5 times, at 2 month intervals, with ELITE plus IPL. Its wavelength was 610~1000 nm, and spot size was 50 mm ? 10 mm. The macro pulse was composed of a series of micro pulses with equal intervals. The micro pulse duration was 5 ms, the number of micro pulse was 4-15, the interval of micro pulse (delay) was 2~20 ms, and the fluence was 22.3～38.3J/cm2. Results All of the patients were well tolerant under no anesthesia. The hairs were mostly or fully removed after 3 to 5 courses of treatment. Routine washing could be done and bandaging was not applied after treatment. There was no blister, infection, hyperpigmentation and scarring. Little vellus hair regrowth was observed after a 6~12 month follow-up. Conclusions IPL is an ideal method to depilate hirsutism of spina bifida occulta because of its credible effect, simple operation, rapid treatment and no serious complication.

Objective To evaluate the changes of QT dispersion (QTd) after successful percutaneous transluminal coronary angioplasty (PTCA) or stent implantation during the recovery period after acute myocardial infarction (AMI).Methods We studied 57 AMI patients who underwent PTCA or stent implantation and 86 normal coronary artery subjects used as control. Maximal and minimal QT interval (QT max and QT min) and QTd (QTd=QT max-QT min) were measured using 12-lead electrocardiography within 1 d before and 1 h after PTCA and stent implantation or coronary angiography.Results QTd and corrected QT dispersion (QTcd) were significantly prolonged in patients with AMI compared with control group. There was no significant difference in QTd and QTcd between anterior AMI and inferior one. QT max, QTc max, QTd and QTcd after PTCA or stent implantation were significantly decreased.Conclusion QTd and QTcd were significantly decreased after successful PTCA or stent implantation which were performed during the recovery period of AMI, which shows it can produce beneficial effects in decreasing the risk of ventricular arrhythmia and reducing mortality in AMI patients.

The β-sheet peptides can be self-assembled to form different supramolecular solids. The supramolecular solid can be linked to a wide range of functional domains, for example, with cell adhesion sequences, signal domains, and vaccine epitopes to form complex nanostructures, which can be widely used in biomedical fields. In this paper, we mainly reviewed the self-assembly of peptides using β-folding secondary structure to form nanostructures, and discussed the application of nanostructures in drug delivery and tissue engineering.

The preventive effects of starch-Fe and sucrose-Fe on iron deficiency anemia were investigated. Weaning rats were used as experimental animal, and divided into starch-Fe, sucrose-Fe, ferrous sulfate and control group. The former 3 groups were set for the Fe deficiency preventive group and each animal received elemental iron 5-6mg per kg body weight per day according to its preparation demand orally. The control group was given ordinary diet only. After 24-day feeding with its experimental diet serum iron(SI), serum ferritin (SF) and hemoglobin (Hb) of the animal were measured. The results revealed that SI (?g/dl) was 111.08 ? 22.30,118.64?26.80, 136.81?54.36 and 83.44?22.60; SF (ng/ml) was 12.69?3.19, 14.52?1.98, 16.91?2.02 and 7.51?2.09; Hb (g/dl) was 10.71?0.63, 10.96 ?0.45, 11.01?0.84 and 8.46 ? 1.27 respectively. This suggested that the starch-Fe and sucrose-Fe could be well absorbed and probably favorable to rescue children from iron deficiency anemia.
