Mild-symptom erectile dysfunction (MSED) is commonly seen in clinical practice, but receives inadequate attention from both the patients and clinicians. Increasing researches have indicated that MSED is associated with not only unhealthy living habits and psychological factors but also the early progression of endothelial, metabolic and endocrine diseases. The diagnosis and treatment of MSED should be based on the relevant guidelines, with consideration of both its specific and common features. The therapeutic principle is a combination of integrated and individual solutions aimed at the causes of the disease. Drug intervention should be initiated if psychological therapy fails. Negligence of MSED may affect the quality of life of the patients and their partners, and what's more, might delay the management of some other severe underlying diseases. Adequate attention to the early diagnosis and treatment for MSED is of great significance for a deeper insight into the etiology of ED, the prevention of potential cardiovascular and metabolic diseases, and the improvement of the overall health of males.

Objective To analyze and discuss the negative effects of atomization inhalation in mechanical ventilation patients in intensive care unit. Methods A retrospective study of all the mechanical ventilation patients in the general ICU of our hospital was carried out from Aprilto December 2015. The risk of multidrug-resistant organisms(MDROs)colonizationin the lower respiratory tract and ventilation associated pneumonia(VAP)in mechanical ventilation patients were analyzed. Results A total of 922 patients were monitored, 160 of whom had atomization inhalation, 92 for MDROs colonizationin the lower respiratory tract and 18 for VAP. The rates ofatomization inhalation in patients with and without MDROs colonizationin the lower respiratory tract were 30.4%(28/92)and 15.9%(132/830)with statistical difference (χ2=12.193, P=0.000). And those in patients with and without VAP were 50.0%(9/18) and 16.7%(151/904), with statistical difference (χ2=11.420, P=0.000). Atomization inhalation was the independent risk factor both of MDROs colonizationin the lower respiratory tract(OR=1.917, 95%CI1.163-3.159, P=0.011) and VAP(OR=4.613, 95%CI 1.773-12.002, P=0.000) in mechanical ventilation patients. Conclusions Atomization inhalation may increase the risk of MDROs colonizationin the lower respiratory tract and VAP in mechanical ventilation patients. Thus unnecessary and too frequent operations of atomization inhalation should be decreased.

Rutaecarpine (Rut) is a type of indole quinazoline alkaloid exracted from Ruticarpum. Studies showed that Rut has a wide range of pharmacological effects, such as anti-hypertension, anticancer, anti-inflammation, anti-thrombus formation. Currently, many scholars are committed to developing it into a new antihypertensive and anti-inflammatory drug with all new mechanisms. But studies found that Rut is a highly fat-soluble drug with low water and oil solubility. Its high insolubility is the main obstacle in its oral absorption and application, which greatly reduced its bioavailability. Therefore, hydroxypropyl-beta-cyclodextrin (HP-beta-CD) was used as the inclusion material to prepare Rut-HP-beta-CD inclusion complex in this experiment, in order to increase its water solubility and bioavailability. In this experiment, the inclusion complex was prepared by the stirring-freeze-dry method. The preparation process was optimized by the orthogonal test, with the inclusion rate as the index, and molar ratio between host and guest molecules, inclusion temperature, time and stirring speed as the impacting factors. Moreover, the inclusion complex was verified by detecting the apparent solubility, thin layer chromatography, microscopic identification, melting point detection and dissolution study. The results showed that under the conditions of the molar ratio between Rut and HP-beta-CD of 1: 1, temperature at 60 degrees C, inclusion time of 4h and stirring speed at 600 r x min(-1), the inclusion rate of Rut-HP-beta-CD reached 91.04%. Therefore, the preparation process of Rut-HP-beta-CD inclusion under the optimum conditions is simple and feasible, with a highest inclusion rate and reproducibility, and could significantly improve Rut's solubility and bioavailability, and provide a reliable experimental basis for its clinical application.

OBJECTIVETo observe the primary prevention role of Wuling Capsule (WC) on poststroke depression (PSD) patients.
METHODSAcute stroke patients were recruited and randomized into 2 groups by stratification, 55 in each group. All patients received same routine treatment of cardiovascular diseases. Patients in the experimental group additionally took WC (0.33 g each pill), 3 pills per day, three times per day; while those in the control group additionally took placebos, 3 pills per day, three times per day. Two weeks consisted of one therapeutic course. The diagnosis of PSD was performed once every other week. Those in accordance with PSD diagnosis discontinued any drug therapy. Those not in accordance with PSD diagnosis continued the drug therapy for 1-12 therapeutic course(s) (in total of 6 months). If they were still not in accordance with PSD diagnosis, then they discontinued the drug therapy. The morbidity of PSD, the average time of depression occurrence, Hamilton depression rating scale (HAMD) score, and adverse reactions were observed.
RESULTSThe 1-, 3-, and 6-month morbidity of PSD was 8%, 16%, and 34% in the experimental group, while they were 19.6%, 29.4%, and 54.9% in the control group. The occurrence rate was lower in the experimental group than in the control group. Besides, there was statistical difference in the 6-month occurrence rate between the two groups (chi2 = 4.465, P < 0.05). The average time of PSD occurrence was longer in the experimental group than in the control group (14.96 +/- 8.31 weeks vs. 9.36 +/- 6.06 weeks; t=6.762, P < 0.05). The HAMD score at the PSD occurrence was 11.96 +/- 2.14 in the experimental group, lower than that of the control group (14.57 +/- 4.24), showing statistical difference (t=5.641, P < 0.05).
CONCLUSIONWC was superior to the placebos in lowering the incidence of PSD, delaying the occurrence time of PSD, attenuating the depression degree of PSD, and had certain preventive effect on the incidence of PSD.

OBJECTIVETo study the effect of ultrafiltration-membrane extracts of Radix Rehmanniae Praeparata (UMERRP) on theproliferation and genetic stability of bone marrow-derived mesenchymal stem cells (BMSCs) induced by cadmium chloride (CdCl2).
METHODSProtective effects on the proliferation, micronuclear rates, chromosome aberration rates, and apoptosis rates were observed by micronuclei test, karyotype analysis, and flow cytometry.
RESULTSCompared with the CdCl2 group, UMERRP with different molecular weights at 0. 8 g/L could obviously promote the proliferation (P <0. 05). Compared with the control group, micronuclear rates, chromosome aberration rates, and apoptosis rates were obviously enhanced in the CdCl2 group (P <0. 05). Compared with the CdCl2 group, UMERRP with different molecular weights could obviously decreased CdCl2 induced micronuclear rates, chromosome aberration rates, and apoptosis rates (P <0. 05). Of them, BMSC micronuclear rates and chromosome aberration rates decreased most obvious in UMERRP groups with molecular weight below 10 000 (P <0. 05). The apoptosis rate decreased most obviously in UMERRP groups with molecular weight ranging 100 000 and 200 000 (P <0. 05).
CONCLUSIONUMERRP could reduce CdCl2 induced micronuclear rates, chromosome aberration rates, and apoptosis rates.
