Objective To investigate the diagnostic efficacy of targeted biopsy(TB)combined with ipsilateral hemiglandular systematic biopsy(SB)of the dominant lesion,so as to explore a novel reduced-core biopsy strategy.Methods A retrospective analysis was conducted on the clinical data of 299 patients treated in our hospital during Sep.1,2022,and Feb.28,2023,who had a Prostate Imaging Reporting and Data System(PI-RADS)score ≥3 and underwent combined TB and SB.The dominant lesion was defined as the lesion with the highest PI-RADS score on multi-parametric magnetic resonance imaging(mpMRI);in cases of identical scores,the largest was designated as the dominant.SB was categorized as ipsilateral(ipsi-SB)or contralateral(contra-SB)to the dominant lesion.The consistency in detecting clinically significant prostate cancer(csPCa)was compared between TB with ipsi-SB(TB+ipsi-SB),TB with contra-SB(TB+contra-SB),and TB with SB(TB+SB).Subgroup analyses were performed based on PI-RADS score,prostate-specific antigen(PSA)level,prostate volume(PV),and mpMRI lesion distribution to evaluate csPCa detection rates across different variables.Results TB+ipsi-SB demonstrated comparable detection rate to TB+SB(46.2％vs.46.8％).The K values for TB+ipsi-SB and TB+contra-SB relative to TB+SB were 0.987(95％CI:0.969-1.000,P＜0.01)and 0.933(95％CI:0.892-0.974,P＜0.01),respectively.Across all subgroups,TB+ipsi-SB showed the highest agreement with TB+SB.Notably,in subgroups with PI-RADS 3 and 5,PSA＞0-20 ng/mL,PV＜25 mL,bilateral or multiple mpMRI lesions,TB+ipsi-SB achieved complete concordance with TB+SB in csPCa detection[K=1.000(95％CI:1.000-1.000),P＜0.01].Conclusion For patients with PI-RADS score ≥3,TB+ipsi-SB exhibits near-perfect consistency with TB+SB in csPCa detection while requiring fewer biopsy cores.TB+ipsi-SB represents a promising refinement of the TB+SB approach.

ObjectiveTo observe the effect of modified Shibaotang on serum sex hormone levels in patients with male late-onset hypogonadism of kidney essence deficiency syndrome complicated with diabetes mellitus. MethodsA total of 60 patients with male late-onset hypogonadism of kidney essence deficiency syndrome complicated with diabetes mellitus，who met the inclusion criteria and were admitted to Yinchuan Hospital of Traditional Chinese Medicine from October 2022 to October 2023，were selected and randomly divided into an observation group and a control group，with 30 patients in each group. Both groups continued their original treatments，including blood glucose lowering and blood lipid regulation. The observation group was treated with modified Shibaotang，while the control group was treated with testosterone undecanoate capsules. The treatment lasted for 12 weeks. The changes in traditional Chinese medicine （TCM）syndrome scores，partial androgen deficiency in aging males （PADAM）symptom scores，glucose metabolism indexes ［fasting plasma glucose （FPG），2-hour postprandial glucose （2 h PG），glycosylated hemoglobin （HbA1c）］，and serum sex hormone indexes ［sex hormone-binding globulin （SHBG），free testosterone （FT），total testosterone （TT），prolactin （PRL），luteinizing hormone （LH），follicle stimulating hormone （FSH），estrogen （E₂）］ were compared between the two groups before and after treatment. Safety was also evaluated. Results（1）Clinical efficacy comparison：After treatment，the clinical efficacy in both groups was similar，and there was no statistically significant difference between the two groups. （2）TCM syndrome score and PADAM symptom score comparison：After treatment，both groups showed a significant reduction in TCM syndrome scores and PADAM symptom scores （P<0.01），and the observation group showed a significantly greater reduction compared to the control group （P<0.05）. （3）Glucose metabolism indexes comparison：After treatment，the levels of FPG，2 h PG，and HbA1c were significantly reduced in both groups （P<0.01），and there was no statistically significant difference between the two groups regarding FPG，2 h PG，and HbA1c levels after treatment. （4）Serum sex hormone indexes comparison：After treatment，the levels of FT，TT，PRL，LH，and FSH were significantly increased in both groups （P<0.01），while E₂ levels were significantly decreased （P<0.01）. There was no statistically significant difference between the two groups in the levels of FT，TT，PRL，LH，FSH，and E₂ after treatment. There was also no significant difference in SHBG levels within or between the groups before and after treatment. During the clinical observation，neither group exhibited any obvious adverse reactions. ConclusionModified Shibaotang can significantly improve the clinical symptoms of male late-onset hypogonadism of kidney essence deficiency syndrome complicated with diabetes mellitus，reduce blood glucose，and increase sex hormone levels. The mechanism may involve the inhibition of aromatase transformation in adipocytes，promotion of GnRH production，and regulation of the hypothalamic-pituitary-gonadal axis function.

Objective:To evaluate the diagnostic value of targeted biopsy of secondary lesion (SL) in systematic biopsy (SB) combined targeted biopsy for clinically significant prostate cancer (CsPCa).Methods:A retrospective analysis was conducted on the data of patients who underwent systematic biopsy combined target biopsy at Nanjing Drum Tower Hospital from January 2021 to February 2023, and they had at least two Prostate Imaging-Reporting and Data System (PI-RADS) score ≥3 lesions on prostate magnetic resonance imaging. The study included patients with a median age of 70 (65, 76) years old, median prostate specific antigen (PSA) was 9.1 (5.96, 13.62) ng/ml, median prostate volume was 39.1 (29.27, 53.25) ml, and median PSAD was 0.2 (0.15, 0.38) ng/ml 2.The index lesion (IL) was defined as the one with the highest PI-RADS score and SL was defined as the one with the second-highest PI-RADS score. If the two lesions had the same PI-RADS score, the one with larger maximum diameter was IL and the other one was SL. The median maximum diameter of IL and SL were 1.3 (1.06, 1.66) cm and 0.9 (0.69, 1.20) cm, respectively. The median maximum diameter ratio of IL and SL was 1.48 (1.10, 1.91), and the median maximum diameter difference of IL and SL was 0.9 (0.20, 1.89) cm. The IL in peripheral zone was found in 238 patients (62.63%) and SL in peripheral zone was found in 255 patients (67.10%). There were 204 patients (53.68%) having both IL and SL on the same side of prostate. According to the combination of PI-RADS scores of IL and SL, patients were categorized into various groups: 96 patients (25.26%) with IL3 and SL3, 79 (20.78%) with IL4 and SL3, 98 (25.78%) with IL4 and SL4, 21 (5.52%) with IL5 and SL3, 76 (20.0%) with IL5 and SL4, and 10 (2.63%) with IL5 and SL5. Targeted biopsy was performed on at least two of the most significant lesions. Comparison was performed in the detection rate of CsPCa between SB+ IL+ SL and SB+ IL (SL was omitted). To explore the factors influencing the detection rate of CsPCa, a multivariate logistic regression analysis was used. Results:The detection rate of CsPCa in this study was 78.95% (300/380) based on SB+ IL+ SL. After omitting SL target biopsy, the detection rate of CsPCa was 78.16% (297/380, P>0.05) under the condition of SB+ IL. No significant differences were noted between the two groups. The multivariate logistic regression analysis showed that PSA ( OR=1.11, 95% CI 1.05-1.20, P<0.01), prostate volume ( OR=0.98, 95% CI 0.96-0.99, P<0.01), SL maximum diameter ( OR=0.19, 95% CI 0.08-0.50, P<0.01), ratio of IL and SL maximum diameter ( OR=0.34, 95% CI 0.16-0.68, P<0.01), difference of IL and SL maximum diameter ( OR=1.50, 95% CI 1.10-2.29, P<0.05), and PI-RADS score group of IL and SL (IL3 vs. SL3 as the reference, IL4 vs. SL3 OR=4.79, 95% CI 2.21-10.91, P<0.01, IL4 vs. SL4 OR=23.11 95% CI 8.09-85.28, P<0.01, IL5 vs. SL3/4/5 OR=15.28 95% CI 5.21-48.55, P<0.01) were the influencing factors for detection rate of CsPCa. Conclusions:For patients with at least two PI-RADS score≥3 lesions on prostate magnetic resonance imaging, omitting SL can almost maintain the same detection efficacy.

Objective:To understand the epidemiological characteristics and spatial distribution of hemorrhagic fever with renal syndrome (HFRS) in Henan Province, and to provide a basis for the development of prevention and control measures.Methods:Data of reported cases with HFRS in Henan Province from January 2012 to December 2022 were obtained from the Chinese disease control and prevention information system subsystem infectious disease monitoring system. Descriptive epidemiological methods were used to analyze the temporal, regional, population distributions, and the type of clinical diagnoses of HFRS. The spatial clustering analyses were carried out at county level. Correlation analysis between different clinical diagnostic types and mortality rate was conducted using Pearson method.Results:A total of 2 843 HFRS cases were reported, with an average annual incidence rate of 0.26/100 000, and 49 cases died with a case-fatality rate of 1.72%. There were two peaks of incidence each year, which were fall and winter (from October to the next January) and late spring and summer peak (from May to July). Among the patients, 2 174(76.47%) were male and 2 294(80.69%) were farmers. The average ages of reported cases from 2012 to 2022 were 43.70 years, 45.44 years, 45.91 years, 48.33 years, 45.41 years, 48.53 years, 48.93 years, 48.87 years, 45.90 years, 51.27 years, and 50.89 years, respectively. There was a strong negative correlation between laboratory-confirmed cases and case fatality ( r=-0.652, P<0.001) , and a strong positive correlation between suspected cases, clinical-diagnosed cases and case fatality ( r=0.304, P=0.035 and r=0.623, P<0.001, respectively). A higher rate of case-fatality was found in areas with a lower number of reported cases. Case-fatality rate ranking among the top five counties were Weidong District (five cases of disease with two deaths), Muye District (three cases of disease with one death), Xinhua District (three cases of disease with one death), Shunhe Hui District (six cases of disease with one death), and Anyang County (53 cases of disease with six (11.32%) death). Global spatial autocorrelation analysis from 2012 to 2022 showed that the Moran′s I coefficients ranged from 0.138 to 0.326, and all of them had a correlation (all P<0.01). The high-high aggregation area was mainly concentrated in the confluence of Zhumadian City and Xinyang City in the south of Henan Province. Conclusions:In Henan Province, the reported cases of HFRS have been distributed throughout the province, with obvious spatio-temporal aggregation in some areas. The average age of reported cases shows a fluctuating upward trend. The rate of laboratory-confirmed diagnosis should be further improved in the high incidence areas.

OBJECTIVE To establish a quantitative analysis of multi-components by single marker （QAMS） method based on a variety of internal reference substances for the content determination of 6 components in Jinlian qingre granules， such as mangiferin， 2″-O-β-L-galactopyranosylorientin， orientin， veratric acid， vitexin， harpagoside. METHODS The determination was performed on Agilent Eclipse Plus C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution （gradient elution） at the flow rate of 1 mL/min. The column temperature was 30 ℃， and the detection wavelength was set at 270 nm. Taking orientin， vitexin and 2″-O-β-L-galactopyranosylorientin as internal references， the relative correction factors （RCF） of the other 5 components to be determined and internal substances were determined by QAMS. The contents of 6 components in 21 batches of Jinlian qingre granules were calculated and then compared with the results of the external standard method. RESULTS The contents of mangiferin， 2″-O-β-L-galactopyranosylorientin， orientin， veratric acid， vitexin and harpagoside in 21 batches of samples were determined by QAMS in the range of 0.234-0.516， 1.804-2.270， 2.143-2.606， 0.190-0.223， 0.594-0.782， 0.080-0.152 mg/g； the contents of them determined by external standard method were 0.235-0.523， 1.798-2.265， 2.137-2.599， 0.190-0.224， 0.597-0.786， 0.077-0.151 mg/g， respectively. The percentage difference between the results measured by the two methods should not exceed 4.00%. CONCLUSIONS QAMS has been constructed for the simultaneous determination of 6 components in Jinlian qingre granules based on a variety of internal reference substances. The results obtained by this method are not significantly different from those obtained by the external standard method， and can be used for the quality control of Jinlian qingre granules.
