RESUMO
OBJECTIVE: Comparison of clinical efficacy between transurethral holmium laser prostate enucleation (two-way rendezvous and trenching method) and transurethral plasma enucleation. METHODS: A total of 483 patients with benign prostatic hyperplasia who were admitted to our hospital from December 2019 to December 2022 were randomly divided into an observation group (245 cases) and a control group (238 cases) using a random number table method. The observation group underwent transurethral holmium laser prostatectomy, while the control group underwent transurethral plasma prostatectomy,evaluate the efficacy of two surgical methods. RESULT: The IPSS symptom score, quality of life (QOL) score, maximum urinary flow rate (Qmax), residual urine volume (PVR) and other indicators were significantly improved in both groups after 6 months of surgery compared to before (P<0.05), and there was no statistically significant difference between the two groups (P>0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group (P<0.05). There was no statistically significant difference in sexual function and retrograde ejaculation between the two groups of patients(P>0.05). CONCLUSION: Both surgical methods have good surgical efficacy, but compared with prostate plasma resection, holmium laser prostatectomy can reduce intraoperative bleeding in patients with BPH, effectively shorten catheter retention time, patient hospitalization time, and postoperative bladder flushing time, resulting in higher quality of life and safety.

In order to explore the status of soil heavy metal pollution and environmental quality in west Hunan, relevant areas of Phoenix County were selected as the study area. Using data from 440 soil samples collected in the study area from June to August 2022, the pH value of the soil and contents of eight heavy metal elements, namely, As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn, were analyzed. The PMF model was used for traceability analysis and geochemical evaluation of soil environmental quality. The results showed that the average values of soil heavy metals ω(Zn), ω(Cr), ω(Pb), ω(Ni), ω(Cu), ω(As), ω(Cd), and ω(Hg) were 81.02, 64.67, 31.63, 29.27, 25.52, 9.93, 0.28, and 0.13 mg·kg-1, respectively. The soil in the study area was mainly weakly acidic, and the contents of the Cd and Hg elements were relatively high compared to the national soil background values and were highly variable. The contents of the Hg and Cd elements in forest land were higher than that in other land uses. The PMF model results showed that the contribution rates of heavy metal pollution sources in the study area were mining sources (37.4%), atmospheric sedimentation sources (7.7%), natural sources (41.1%), and agricultural activity sources (13.8%) and provided suggestions on pollution control measures according to the spatial distribution of the four types of pollution sources. Through the comprehensive assessment of soil environmental geochemistry, the study area was divided into three types of plots, namely, non-risk areas (94.27 km2), accounting for 76.38%; risk-controllable areas (27.45 km2), accounting for 22.24%; and high-risk areas (1.7 km2), accounting for 1.38%. This study provided data support for the prevention and control measures of land pollution in the research area, as well as the delineation of the prevention and control scope.
RESUMO
The naturally high background value region of Cd derived from the weathering of carbonate has received wide attention. Due to the significant difference in soil physicochemical properties, soil Cd content, and bioavailability of different parent materials in the karst area, there are certain limitations in using the total soil Cd content to classify the environmental quality of cultivated land. In this study, surface soil and maize samples of eluvium and alluvial parent material in typical karst areas were collected systematically; the contents of maize Cd, soil Cd, pH, and oxides were analyzed, the Cd geochemical characteristics of different parent soils and the influencing factors of their bioavailability were revealed, and scientific and effective arable land use zoning suggestions based on the prediction model were suggested. The results showed that the physicochemical properties of different parent material soils in the karst area were obviously different. The alluvial parent material soil had low Cd content but high bioavailability, and the maize Cd exceeding rate was high. The maize Cd bioaccumulation factor was significantly negatively correlated with soil CaO, pH, Mn, and TC, and the correlation coefficients were -0.385, -0.620, -0.484, and -0.384, respectively. Compared with the multiple linear regression prediction model, using the random forest model to predict the maize Cd enrichment coefficient had higher accuracy and precision. Furthermore, a new scheme for the safe utilization of cultivated land at the plot scale based on soil Cd and predicted crop Cd content was proposed in this study, making full use of arable land resources to ensure crop safety.
RESUMO
Asian leaf-litter toads of the genus Leptobrachella represent charismatic anuran diversification with 80 species, of which 25 are from China. Recent new discoveries suggest that the diversity of this genus is underestimated. Here, we describe a new species of Leptobrachella, Leptobrachella bashaensis sp. nov. from the Basha Nature Reserve, Congjiang County, Guizhou Province, China. The new species is distinguished from its congeners by the following suite of morphological traits: small body size (SVL 22.9-25.6 mm in six adult males and 27.1 mm in one adult female); head longer than wide; dorsal skin slightly shagreened with small tubercles; creamy-white chest and belly with irregular black spots; distinct ventrolateral glands forming a white line; finger webbing and fringes absent; toe webbing rudimentary and lateral fringes narrow; iris bicolored with bright orange in upper half and silver in lower half; dorsal surface of tadpole head dark brown with small, brown, irregular spot, air sac-shaped bulges on both sides of body. The new species differs from all known congeners by an uncorrected p-distance of >5.3% of the 16S rRNA gene fragment examined, and the phylogenetic analysis clusters the new species with L. maoershanensis and L. laui. At present, the new species is only known from a small range of montane evergreen secondary forests in Basha Nature Reserve approximately 900 m elevation. Its natural history and conservation status are discussed.
RESUMO
The user experience (EX) of current Electronic Medical Record systems (EMR) is needed to improve. This paper proposed a new method to enhance EX of EMR. Firstly, system template and text characterization are used to make the EMR data structured. Then, the structured date are mined based on mining the association rules of incremental updating data to find the association of the elements of template of EMR and the values of elements. Finally, with the help of mined results, the users of EMR are able to input data effectively and quickly.

The Papenfuss' Rock Agama Laudakia papenfussi is an endemic species in the Tibet Autonomous Region of China. The complete mitochondrial genome sequence of this species was determined by shotgun sequencing. The total length of mitogenome is 17,005 bp and its base composition was 37.3% for A, 23.9% for T, 12.5% for G, and 26.3% for C, which contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 2 control regions. The phylogenetic tree of L. papenfussi and 15 other related species was reconstructed using maximum likelihood (ML) methods. The mitogenome sequence presented here will be useful to understand the phylogenetic relationships of Laudakia.
RESUMO
The complete mitochondrial genome (mitogenome) sequence of Sphenomorphus indicus was sequenced and characterized by next-generation sequencing technology. The total length of mitogenome is 17,027 bp and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 2 non-coding regions (the control region and the putative L-strand replication origin). Most of the genes of S. indicus are encoded on the H-strand, except for the ND6 subunit gene and 8 tRNA genes which is distributed on the L-strand. Phylogenetic reconstruction suggested that S. indicus is the sister group of the S. incognitus within the genus Sphenomorphus. The complete mitochondrial genome sequence presented here will be useful to study the evolutionary relationships and genetic diversity of S. indicus.
