Objective To explore the effect of acupoint sticking combined with electrical stimulation on limb function in stroke patients. Methods A total of 82 stroke patients who treated in Intergrated Chinese and Western Medicine Hospital of Zhejiang Province from September 2015 to September 2016 were selected in this study. The participants were divided into the observation group (n=41) and the control group (n=41) according to the random number table. Both groups received conventional therapy and electrical stimulation while the observation group combined with additional acupoint sticking. The Lowett score, ADL score, FMA score of limb motor function, and walking ability evaluation were compared between two groups after 12 weeks' course of treatment. Results The total treatment efficiency in the observation group was significantly higher compared with the control group (92.68% vs. 68.29%; P<0.05). Both groups had increased scores of Lowett, ADL, and FMA, however, the observation group had significantly higher scores compared with the control group (P< 0.05). Regarding the walking ability, the walking speed and stride frequency were increased in both groups but significantly improved in the observation group compared with the control group (P< 0.05). Conclusions The acupoint sticking combined with electrical stimulation therapy can effectively improve the limb function in patients with stroke.

Objective To observe clinical efficacy of probiotics agents in the prevention and treatment of severe pulmonary infection in elderly patients with antibiotic-associated diarrhea (AAD).Methods 60 cases of elderly patients with severe pulmonary infection (more than or equal to 60 years old) were randomly divided into the treatment group ( 31 cases ) and control group ( 29 cases ) , the control group received broad-spectrum antibiotics or using two linked above anti-infection treatment, the treatment group were added with probiotic agent ( lactobacillus complex capsules).The diarrhea, the use of antibiotics and the stool routine, bacteria before and after 5, 10, 15 days of group were observed.Results After 15 days treatment, the number of Escherichia coli in treatment group was lower than that in control group (P<0.05), the number of Bacterium lacticum and Bifidobacterium bifidum in treatment group were higher than those in control group ( P<0.05 ) .The AAD rate in treatment goup was 12.90%, which was lower than 41.38% in control group (P<0.05).There were significant differences in beginning time and duration of diarrhea between two groups (P<0.05). Conclusion The intestinal probiotics reduced induced by antibiotics in elderly patients with severe pulmonary infection , the probiotics agents could redress intestinal flora imbalance, keep the steady state of intestinal flora, and prevent and cure the antibiotic-associated diarrhea.

OBJECTIVETo explore the stability of seminal plasma miR-122-3p and miR-141-5p and their diagnostic value for idiopathic asthenospermia.

METHODSSeminal plasma miR-122-3p and miR-141-5p with various incubation time, freeze-thaw cycles and incubation time were analyzed. Real-time fluorescence quantitative polymerase chain reaction (RT-PCR) was used to detect the content of miR-122-3p and miR-141-5p, with U6 snRNA as the reference. The idiopathic asthenospermia group was further divided into grade I and II based on the progressive motility percent, and the content of miR-122-3p and miR-141-5p in the two grades were compared.

RESULTSNo difference was detected after incubation at room temperature and 4 degrees Celsius. But seminal plasma miR-122-3p and miR-141-5p have decreased along with the increase in freeze-thaw cycles increases. RT-PCR assayed showed that the miR-122-3p content in the idiopathic asthenospermia group was significantly lower than the control group, while miR-141-5p was significantly higher. The difference in both miR-122-3p and miR-141-5p content was statistically significant (P < 0.05). A significant difference in miR-122-3p and miR-141-5p content between a and b groups was also detected (P < 0.05). The AUC-ROC of miR-122-3p was 0.88. At the cutoff value of 1.02, the sensitivity and specificity was 83% and 84%, respectively. At the cutoff of 2.95, the AUC-ROC of miR-141-5p was 0.88. The sensitivity and specificity was 84% and 70%, respectively.

CONCLUSIONMiR-122-3p and miR-141-5p in seminal plasma are stable and have certain value for the diagnosis of idiopathic asthenospermia.

Polyhydroxyalkanoates (PHAs), as a novel class of biopolymer, are attracting more attention due to their diverse material properties and environment-independent biodegradability. Here we report the preparation of PHA exhibiting efficient antibacterial activity by embedding Nisin, a food additive generally recognized as safe, into poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx), a type of PHA with high biocompatibility. We first prepared Nisin-containing PHBHHx films using solvent casting method. Confocal laser scanning microscopy analysis showed that a well-mixed integrated structure of the films with an even distribution of the Nisin particles in the PHBHHx matrices. Then the antimicrobial activity of PHBHHx/Nisin films against Micrococcus luteus was quantified on agar plate by measuring the size of inhibition zone. Cultivation in liquid media further confirmed the releasing of Nisin from the films and the long-time antibacterial activity. Results showed that the threshold of Nisin concentration for long-time and effective inhibition against bacteria growth is 25 μg/g. These results altogether establish a technological foundation for the application of PHA in biomedicine and food industry.
