Objective : To study the effect of modified holmium laser enucleation of the prostate (HoLEP) on sexual function in patients with benign prostatic hyperplasia (BPH). Methods ¡¤ The clinical data of 167 middle-aged and elderly patients with BPH treated by modified HoLEP from Feb. 2017 to Oct. 2018 were retrospectively analyzed. According to the status of sexual activity after operation, the patients were divided into study group who had sex (65 cases) and control group who had no sex (102 cases). The risk factors of sexual activity after operation in the two groups were analyzed. The changes of erectile function and ejaculatory function in the study group before and after operation were recorded and analyzed by international index of erectile function (IIEF-5) score, erection hardness score (EHS) model and ejaculatory function question-naire. Results ¡¤ There were no significant differences between the two groups in the stress urinary incontinence, postoperative hospitalization time, weight of enucleated prostate, crush time, total prostate specific antigen, preoperative urinary retention and enucleation time. The patients in the study group were younger than those in the control group (P=0.000). There were no significant differences in IIEF-5 score and EHS in the study group before and 1, 3, 6 months after operation. There were no significant differences in shorten ejaculation latency, ejaculation pain and ejaculation with or without semen in the study group before and after operation, but the patients of decreased semen volume increased from 41.82% (23/55) to 92.73% (51/55) (P=0.000). Conclusion ¡¤ Age is a risk factor in BPH patients, whether there is sexual activity after modified HoLEP or not. The modified HoLEP has no significant effect on erectile function, but the effect on ejaculatory function is the decrease of ejacu-lated semen volume.

Objective To explore the effect of smoking on blood glucose level among male patients with type 2 diabetes in Changshu City.Methods Totally 41 57 male patients with type 2 diabetes involved in the national basic public health service were selected and assigned into four groups,including heavy smokers,current mild smokers,former smokers and non -smokers.All of them were investigated about the general social demographic data,living habits and health condition.Height,weight,waist and hipline were measured.BMI and WHR were calculated.FPG and HbA1 c were checked.Covariance analysis was used to correct the confounding factors,and the methods of multiple linear regression and partial correlation were used to evaluate the relationship between smoking and blood glucose level.Results FPG of the heavy smokers was higher than the current mild smokers,former smokers and non -smokers(P <0.05),but after the correction of the confounding factors,the differences were not statistically significant(P >0.05).HbA1 c of the heavy smokers and current mild smokers were higher than the former smokers and non -smokers(P <0.05 ),and after the correction of the confounding factors,the differences were still statistically significant(all P <0.05).Daily smoking amount was one of the influencing factors of HbA1 c(β=0.07,P <0.05).There was no correlation between the age of smoking initiation and FPG,HbA1 c(P >0.05).Daily smoking amount was positively correlated with HbA1 c(r =0.06,P <0.05), but was not correlated with FPG(P >0.05).Conclusion Smoking has a certain degree of influence on blood glucose level among male patients with type 2 diabetes in Changshu City,and we need to reduce the smoking rate among male patients with type 2 diabetes by health education.

This study was purposed to explore the relationship between asparagine synthetase (AsnS) mRNA expression level and the sensitivity of leukemic cell lines to L-asparaginase. The AsnS mRNA expression level in 8 cell lines (Jurkat, HL-60, U937, NB4, THP-1, Namalwa, Karpas299 and K562) was determined by real-time quantitative PCR (RQ-PCR) based on fluorescence dye Eva Green before and after treatment with L-Asp, and the cell proliferation rates were analyzed by CCK-8 assay. The results showed that there was a significant disparity of AsnS expression level in 8 cell lines, and there were significant increases of AsnS expression level in cells co-cultured with L-Asp (p < 0.05). Of all these eight cell lines, cells sensitive to L-asparaginase had lower AsnS expression level and cells resistant to L-asparaginase had higher AsnS expression. U937 which was the most sensitive to L-asparaginase had the lowest AsnS expression level, while K562 was natural resistant to L-asparaginase and possessed of the highest AsnS level. It is concluded that the AsnS plays a critical role in regulating cellular biological behavior after depletion of asparagine, the AsnS mRNA expression level in cells reflects the sensitivity of cells to L-Asp. The results may imply the possibility for the use of L-asparaginase in leukemia with lower AsnS expression level.

Background: The effect of nano controlled sequential release of trichloroacetic acid (TCA) and epidermal growth factor (EGF) on the oral soft tissue regeneration was determined. Methods: Hydrophobically modified glycol chitosan (HGC) nano controlled system was developed for the sequential release of TCA and EGF, and the release pattern was identified. The HGC-based nano controlled release system was injected into the critical-sized defects created in beagles’ palatal soft tissues. The palatal impression and its scanned body was obtained on various time points post-injection, and the volumetric amount of soft tissue regeneration was compared among the three groups: CON (natural regeneration control group), EXP1 (TCA-loaded nano controlled release system group), EXP2 (TCA and EGF individually loaded nano controlled release system). DNA microarray analysis was performed and various soft tissue regeneration parameters in histopathological specimens were measured. Results: TCA release was highest at Day 1 whereas EGF release was highest at Day 2 and remained high until Day 3. In the volumetric measurements of impression body scans, no significant difference in soft tissue regeneration between the three groups was shown in two-way ANOVA. However, in the one-way ANOVA at Day 14, EXP2 showed a significant increase in soft tissue regeneration compared to CON. High correlation was determined between the histopathological results of each group. DNA microarray showed up-regulation of various genes and related cell signaling pathways in EXP2 compared to CON. Conclusion HGC-based nano controlled release system for sequential release of TCA and EGF can promote regeneration of oral soft tissue defects.

Objective To characterize a species of the genus Tricula and parasitized trematodes in schistosomiasis-endemic areas of Yunnan Province using a molecular analysis, so as to understand their taxonomic positions. Methods Tricula spp. and Oncomelania snails were collected from Xiangyun County, Yunnan Province, and cercaria parasitizing snails were observed using crushing followed by microscopy. Cercaria parasitizing Tricula snails at various morphologies were sampled using a shedding method. Genomic DNA was extracted from snail soft tissues and cercariae, and the 16S rRNA, COI, 28S rDNA genes in snails and the ND1 and 28S rDNA genes in cercariae were amplified using a PCR assay and sequenced. The species of Tricula snails and their parasitized trematodes was characterized using sequence alignment and phylogenetic analysis. Results Among 382 Tricula snails detected, there were three types of trematode cercariae found, including the non-forked (20.94%, 80/382), double-forked (3.40%, 13/382) and swallow shapes (7.07%, 27/382). Sequence and phylogenetic analyses showed that the 16S rRNA, COI and 28S rDNA gene sequences of this species of Tricula had high homology to those in Delavaya dianchiensis, and were clustered in a branch. Sequencing analysis of the ND1 and 28S rDNA genes revealed that the non-forked cercariae belonged to the family Pleu- rogenidae, the swallow-shaped cercariae belonged to the family Opecoelidae, and the double-forked cercariae belonged to another species of the genus Schistosoma that was different from S. sinensium and S. ovuncatum. Conclusion The species and taxonomy of Triculla spp. and their parasitized trematodes are preliminarily determined in schistosomiasis-endemic areas of Yunnan Province; however, further studies are required to investigate the more definite taxonomy and pathogenicity.
