Objective To investigate the value of low-pressure laparoscopic technique for appendicitis surgery during early and mid-term pregnancy.Methods The clinical data of 13 pregnant women underwent low-pressure laparoscopic appendectomy from July 2007 to December 2010 were analyzed retrospectively.Results All the 13 cases were performed laparoscopic appendectomy successfully without laparotomy and cured completely before discharged from hospital No intestinal fistula,wound infection,abortion and other complications occurred.During follow-up,9 cases of full-term pregnancy patients gave birth to healthy babies,and there was no abortion and premature delivery on 4 patients still in their pregnancy.Conclusion For women at early or mid-term pregnancy with acute appendicitis,low-pressure laparoscopic appendectomy could reduce the stimulus of surgical operation on uterus and decrease the risk of abortion.

Objective To explore the application effects of hip muscle training on female patients with stress urinary incontinence (SUI).Methods Totally 48 female patients with mild to moderate SUI were recruited in this study from the Second Hospital of Hebei Medical University from January to November 2015 by using purposive sampling method. According to the random number table,the participants were divided into the intervention group (n=24) and the control group (n=24). Patients in the intervention group received resisted hip muscle exercise,including the hip internal rotation and hip external rotation. Patients in the control group received conventional pelvic floor muscle exercise (PFME). The intervention lasted for 12 weeks,and the application effects were evaluated by the questionnaire of urinary incontinence quality of life (I-QOL) and the urine pad test before the intervention,eight weeks,and 12 weeks after the intervention.Results After the intervention,the urine leakage was significantly decreased,and the I-QOL score was increased (P<0.05). Although the urine leakage had no statistical difference between two groups (P>0.05),the total I-QOL scores and the scores of social barriers dimension were higher inr the intervention group compared with that in the control group (P<0.05). But on the dimension of limited behavior and the psychological impact,there were no statistical differences between two groups (P>0.05).Conclusions Resisted hip muscle training can effectively decrease the urine leakage and improve the quality of life of female patients with mild to moderate SUI.

Urinary incontinence is a common disease of women. Approximately there are two billion patients with urinary incontinence globally, SUI accounts for almost 1/2 of urinary incontinence. Stress urinary incontinence not only affects women′s health and limits the patients′ daily behavior and physical activity, resulting in anxiety, depression, etc. In view of the high prevalence of SUI, the high impact rate and low rate of diagnosis and treatment, the clinical medical professionals need to understand the relevant contents of SUI. This review will summarize the risk factors about stress urinary incontinence and the development of pelvic floor muscle rehabilitation. We hope to provide reference for clinical practice.

To investigate the formation of polystyrene nanoplastic-plant protein corona and its potential impact on plants, three differently modified polystyrene nanoplastics with an average particle size of 200 nm were taken to interact with the leaf proteins of Impatiens hawkeri for 2 h, 4 h, 8 h, 16 h, 24 h, and 36 h, respectively. The morphological changes were observed by scanning electron microscopy (SEM), the surface roughness was determined by atomic force microscopy (AFM), the hydrated particle size and zeta potential were determined by nanoparticle size and zeta potential analyzer, and the protein composition of the protein corona was identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The proteins were classified in terms of biological processes, cellular components, and molecular functions to study the adsorption selection of nanoplastics to proteins, investigate the formation and characteristics of polystyrene nanoplastic-plant protein corona and predict the potential impact of protein corona on plants. The results showed that the morphological changes of the nanoplastics became clearer as the reaction time extends, as evidenced by the increase in size and roughness and the enhancement of stability, thus demonstrating the formation of protein corona. In addition, the transformation rate from soft to hard protein corona was basically the same for the three polystyrene nanoplastics in the formation of protein corona with leaf proteins under the same protein concentration conditions. Moreover, in the reaction with leaf proteins, the selective adsorption of the three nanoplastics to proteins with different isoelectric points and molecular weights differed, and the particle size and stability of the final formed protein corona also differed. Since a large portion of the protein fraction in protein corona is involved in photosynthesis, it is hypothesized that the formation of the protein corona may affect photosynthesis in I. hawkeri.
