Objective: To explore the learning curve of transurethral 450 nm blue light vaporization of the prostate (TUBVP) in a district hospital,in order to provide reference for clinicians who plan to perform TUBVP. Methods: The clinical data of 56 patients with benign prostatic hyperplasia (BPH) who received TUBVP performed by the same group of surgeons in Chang'an District Hospital during Jun. and Dec. 2023 were retrospectively analyzed. Cumulative sum (CUSUM) was used to fit the learning curve of ratio of volume to operating time (RVOT) of prostate volume /450 nm blue light. The learning curve was divided into different stages according to the inflection points,and the clinical data of patients operated at different stages were analyzed and compared. Results: The learning curve of TUBVP was 21 cases,including 1-21 cases in the learning stage,22-38 cases in the improvement stage and 39-56 cases in the maturity stage. With the increase of cases,the postoperative bladder irrigation time reduced \[40.00 (26.00,44.50) h vs. 23.00(20.50,34.00) h vs. 23.50(14.75,40.75) h\],with statistical difference (P<0.05). The surgical efficiency increased \[(0.51±0.14) vs. (0.55±0.17) vs. (0.63±0.23)\],while the reduction of hemoglobin \[(6.43±7.35) g/L vs. (5.65±10.91) g/L vs. (2.61±7.36) g/L\],catheter indwelling time \[70.0 (66.0,106.0) h vs. 71.0 (66.0,89.0) h vs. 66.0 (58.5,78.5) h\],and incidence of complications (9.5% vs. 5.9% vs. 0) in the three stages showed a gradually decreasing trend,but with no statistical significance (P>0.05). Conclusion: The learning curve of TUBVP is 21 cases. For clinicians in district hospitals,TUBVP is a worthy choice.

ObjectiveTo reveal the correlation of Rehmannia glutinosa-soil feedback process with the formation of its continuous cropping obstacles through the identification of the root exudates of R. glutinosa and analysis of the specific rhizomicrobes recruited by the root exudate. MethodThe root exudates of R. glutinosa seedlings germinated under sterilized condition and those enriched in the rhizosphere of R. glutinosa cultivated in the field were collected and analyzed using the ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS). The highly abundant compounds identified in the root exudates were added into blank soil, and the soil microbial community was profiled using Illumina Miseq sequencing. The bacterial and fungal functions were predicted by PICRUSt and FUNGuild, respectively. ResultThe identification results showed that seven phenylethanoid glycosides were found in R. glutinosa root exudates, and acteoside possessed the highest abundance. In the soil enriched with acteoside, the bacterial genera such as Agromyces, Pseudomonas, Lysobacter, Sphingobium, Pseudoxanthomonas and Sphingomonas were enriched. For the fungi, the genera Neocosmospora, Plectosphaerella and Dactylonectria, and the species such as Neocosmospora rubicola, Plectosphaerella cucumerina, Dactylonectria alcacerensis and Fusarium solani showed higher abundance. The functional analysis indicated the above-mentioned bacterial genera may realize rapid proliferation by utilizing, biodegrading and transforming phenylethanoid glycosides, and some potential fungal pathogens were colonized. ConclusionThe R. glutinsoa-soil feedbacks were likely generated by the phenylethanoid glycosides in the root exudates together with the specific rhizomicrobes. The investigations of R. glutinsoa-soil feedbacks under continuous cropping system are critical to the further understanding of the underlying mechanisms related to its continuous cropping obstacles.

Objective:To explore the characteristics of natural foci of hemorrhagic fever with renal syndrome (HFRS) in Gansu Province.Methods:The information of HFRS case data and rodent density monitoring data from 2012 to 2022 in Gansu Province were collected and epidemiological methods were used to analyze and investigate the characteristics of the epidemic focus.Results:A total of 869 cases of HFRS were reported, and four patients died from 2012 to 2022. The annual incidence rate is between 0.05 per 100 000 and 1.21 per 100 000. The cases were mainly distributed in the eastern, southeast, southern, and south of the central region of Gansu Province. Most cases were distributed between age 20-60, and the sex ratio was 1.85∶1 (564∶305). Most cases were farmers (61.80%, 537/869), herdsmen (19.79%,172/869) and students (6.33%, 55/869). In a wild rat-type epidemic focus,the incidence peak was from November to January of the following year. The natural rodent hosts of HFRS were Rattus norvegicus, Apodemus agrarius, and Mus musculus. The hantaan virus carriage rates were 2.79% (21/754), 0.42% (5/1 179) and 0.31% (2/643),respectively. Three epidemic foci were defined: two derived from the Pingliang and Gannan prefecture new outbreaks epidemic foci, respectively, while the other was the residue of the Dingxi epidemic focus. Conclusions:The southern, south of the central region and eastern part of Gansu Province are current key HFRS epidemic foci dominated by Rattus norvegicus, Apodemus agrarius, and Mus musculus, respectively. The virus genotype is hantaan virus. Case reporting areas should strengthen epidemic monitoring; the key epidemic areas should strengthen and implement various prevention and control measures to reduce the harm caused by HFRS.

Objective:To explore the medication law of gilles de la Tourette syndrome (TS) in ancient TCM books through data mining.Methods:TS related disease information was searched by searching Chinese Medicine Collection Database 4.0 and Chinese Medical Classics 5.0 about liver wind, convulsion, infantile convulsion, slow infantile convulsion, Chi Zong, Jin Ti Rou Yu, chronic spleen wind. Excel 2022 software was used to input the main symptoms, etiology and pathogenesis, treatment methods and prescriptions of each disease, and the frequency, property and taste, meridian tropism and efficacy of medication were analyzed. Gephi 0.9.2 software was used to analyze the complex network of Chinese materia medica data to find out the core drugs. SPSS Statistic 25.0 software was used for clustering analysis of high-frequency Chinese materia medica (top 50 in frequency ). SPSS Modeler 14.2 software was used to analyze the association rules of high-frequency Chinese materia medica based on Apriori algorithm. Results:Totally 692 ancient prescriptions were included, involving 436 kinds of Chinese materia medica. The top five in terms of frequency were: Scorpio, Cinnabaris, Moschus, Typhonii Rhizoma, Gastrodiae Rhizoma appeared the most frequently. The main property was cold, the main taste was pungent, and mainly into the liver, spleen, and heart meridians; the core drugs were Bombyx Batryticatus, Pinelliae Rhizoma, and Glycyrrhizae Radix et Rhizoma. Clustering analysis could be divided into 8 categories. Correlation analysis showed that Scorpio→Bombyx mori Linnaeus and Cinnabaris had the highest support, while Cinnabaris→Bovis Calculus→Moschus→Scorpio had the highest confidence.Conclusions:Ancient doctors believed that the disease location of TS-related diseases are mainly liver, heart, spleen and kidney, and the pathogenic factors were mainly wind, fire, phlegm, blood stasis and deficiency. The insect snakes used in prescription drugs are used to search for wind and eliminate pathogenic factors, the epigraphy is used to calm the nerves and calm the wind, and the herbs are used to soothe the wind, clear heat, calm the liver and dispel phlegm.
