El laboratorio de fertilidad masculina, su evolución en los últimos 20 años / The male fertility laboratory, its evolution over the last 20 years / O laboratório de fertilidade masculina, sua evolução ao longo dos últimos 20 anos

Resumen La mayor accesibilidad a los tratamientos de reproducción asistida (RA) y los avances de la criobiología produjeron cambios en los laboratorios de andrología. El objetivo de este trabajo fue analizar la demanda y evolución de las variables seminales en las últimas dos décadas, caracterizar el laboratorio andrológico actual, evaluar el impacto de la incorporación del aseguramiento de la calidad y la inclusión de los sistemas computarizados (CASA). Se utilizaron datos de las medias mensuales del control de calidad interno (n=22 528) y encuestas a profesionales de laboratorios andrológicos (n=65) y a médicos especialistas en fertilidad (n=33). La demanda global se redujo significativamente con el aumento de las solicitudes de primera vez. El volumen y recuento, variables dependientes de andrógenos, disminuyeron con los años. El criterio estricto en morfología disminuyó el porcentaje de normales; la mitad de los médicos encuestados recibieron resultados entre 0 y 10% y el 40% consideró que ponía en riesgo el valor clínico de la variable. El sistema CASA permitió objetivar la cinética espermática e incrementar el porcentaje de progresivos rápidos, pero pocos laboratorios lo incorporaron. El 66% de los médicos resuelven el factor andrológico severo por tratamientos clínicos y el 95% utiliza técnicas de RA. El análisis de semen es ejecutado fundamentalmente por bioquímicos especializados, con baja adhesión a la automatización y acreditación del laboratorio, pero con participación en programas de evaluación externa de calidad. La demanda disminuyó como consecuencia del aumento del tratamiento por RA. La reducción del porcentaje de formas normales compromete su utilidad clínica.

Abstract Increasing availability to assisted reproduction (AR) treatments in Argentina and advances in cryobiology resulted in changes in andrology laboratories. The aim of this study was to evaluate the demand and evolution of seminal variables in the last two decades, characterise the current andrology laboratory, evaluate the impact of the incorporation of quality assurance and the introduction of computer assisted semen analysis (CASA). Data were taken from internal quality control (IQC) monthly means (n=22 528) and professionals in charge of laboratories (n=65) and fertility physicians' (n=33) surveys. Overall demand decreased significantly while first-time orders increased. Sperm volume and sperm count -androgen dependent parameters- decreased over the years. Strict morphology criteria reduced the percentage of normal results; half of the physicians received results between 0 and 10% and 40% considered that it compromised the clinical value of the variable. The CASA system made it possible to objectify sperm kinetic, increasing the percentage of fast progressives, but few laboratories have incorporated it. Sixty-six percent of physicians resolve severe andrological factor by clinical treatments and 95% use AR techniques in those cases. Semen analysis is mainly performed by specialised biochemists, with low adherence to laboratory automatisation and accreditation, but with participation in external quality assessment programmes. The demand decreased because of the increase in AR treatment. The lower percentage of normal forms compromises their clinical utility.

Challenges of computer-assisted orthognathic surgery in clinical application / 口腔疾病防治

@#After years of development, the advantages of computer-assisted orthognathic surgery have been widely recognized. However, the clinical application of this technology is challenging. Each step may generate errors from data acquisition, computer-assisted diagnosis, and computer-assisted surgical design, causing errors to be transferred from the virtual surgical plan to the operation. The accumulation and amplification of errors will affect the final surgical effect. Currently, digital devices, such as intraoral scanners, are being explored for error control, utilizing automation methods and algorithms, and implementing personalized bone positioning methods. Moreover, there are still many problems that have not been fully resolved, such as precise simulation of postoperative soft tissue, functional assessment of mandibular movement, and absorbable internal fixation materials. Fully understanding computer-assisted orthognathic surgery's limitations could provide direction for optimizing existing methods while helping clinicians avoid risks and maximize its advantages to achieve the best outcome. Many emerging and cutting-edge technologies, such as personalized titanium plates, artificial intelligence, and surgical robots, will further promote the development of this discipline. We can expect future optimization of digital orthognathic surgical technology by innovations in automation, intelligence, and personalization.

Short-term efficacy of surgical treatment for multiple pulmonary nodules: A retrospective study in a single center / 中国胸心血管外科临床杂志

@#Objective To summarize and analyze the clinical diagnosis, surgical treatment and prognosis of multiple pulmonary nodules (MPNs). Methods The clinical data of lung cancer patients who received surgical treatment in our hospital from 2018 to 2020 were collected. The short-term efficacy of surgical treatment for MPNs was analyzed. Results A total of 97 patients were enrolled, including 30 males and 67 females with an average age of 56.1±10.0 years at onset ill. There were 62 patients with double lesions, 22 patients with three lesions, 4 patients with four lesions, and 9 patients with more than four lesions. A total of 213 lesions were surgically treated, including 88 pure ground-glass nodules, 81 partially solid nodules, and 7 solid nodules. There were 87 simultaneous surgeries and 10 staged surgeries, with an average operation interval of 5.2 months. The pathological combination type included adenocarcinoma-adenocarcinoma in 96 (99.0%) patients, squamous cell carcinoma-squamous cell carcinoma in 1 (1.0%) patient, and no lymph node metastasis was found. The 2-year disease-free survival (DFS) rate was 92.1%, and the overall survival (OS) rate was 100.0%. Univariate analysis showed that high-risk lesion size>2 cm (P=0.316), residual lesions (P=0.782) and pathological combination type (P=0.913) had statistical effect on the 2-year DFS rate. Conclusion MPNs are mainly diagnosed with multiple primary lung cancers, and the pathological combination is mostly adenocarcinoma-adenocarcinoma combination. Imaging examination is of great help to the surgical approach selection, diagnosis and differential diagnosis of MPNs. During the operation, maximal preservation of lung function and complete resection of high-risk nodules should be taken as the principle, and the prognosis is satisfactory.

Clinical efficacy of da Vinci robotic and thoracoscopic transxiphoid approach in the treatment of anterior mediastinal tumors: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective To compare the safety and efficacy of the da Vinci robot and thoracoscopic subxiphoid approach for the treatment of anterior mediastinal tumors. Methods The clinical data of patients who underwent anterior mediastinal tumor resection through the subxiphoid approach admitted to the same medical group in the Department of Thoracic Surgery of the First Hospital of Lanzhou University between June 2020 and April 2022 were retrospectively analyzed. According to the surgery approach, the patients were divided into a robot-assisted thoracoscopic surgery (RATS) group and a video-assisted thoracoscopic surgery (VATS) group. The perioperative data and the incidence of postoperative complications were compared between the two groups. Results A total of 79 patients were enrolled. There were 41 patients in the RATS group, including 13 males and 28 females, with an average age of 45.61±14.99 years. There were 38 patients in the VATS group, including 14 males and 24 females, with an average age of 47.84±15.05 years. All patients completed the surgery successfully. Hospitalization cost and operative time were higher or longer in the RATS group than those in the VATS group, and the difference was statistically significant (P<0.05). Intraoperative bleeding, postoperative hospital stay, postoperative water and food intake time, postoperative off-bed activity time, white blood cell count, neutrophil percentage and visual analogue scale (VAS) score on the first postoperative day, white blood cell count and neutrophil percentage on the third postoperative day, duration of analgesic pump use, the number of voluntary compressions of the analgesic pump, and mediastinal drainage volume were all superior to those in the VATS group (P<0.05). The differences in VAS scores on the third postoperative day, duration of drainage tube retention and postoperative complication rates were not statistically different between the two groups (P>0.05). Conclusion RATS subxiphoid anterior mediastinum tumor resection is a safe and feasible surgical method with less injury and higher safety, which is conducive to rapid postoperative recovery and has wide clinical application prospects.

@#Objective To explore the reliability and safety of continuous monitoring of vital signs in patients using wireless wearable monitoring devices after video-assisted thoracoscopic surgery (VATS) for lung cancer. Methods The patients undergoing VATS for lung cancer in West China Hospital, Sichuan University from May to August 2023 were prospectively enrolled. Both wireless wearable and traditional wired devices were used to monitor the vital signs of patients after surgery. Spearman correlation analysis, paired sample t test and ratio Bland-Altman method were used to test the correlation, difference and consistency of monitoring data measured by the two devices. The effective monitoring rate of the wireless wearable device within 12 hours was calculated to test the reliability of its continuous monitoring. Results A total of 20 patients were enrolled, including 15 females and 5 males with an average age of 46.20±11.52 years. Data collected by the two monitoring devices were significantly correlated (P<0.001). Respiratory rate and blood oxygen saturation data collected by the two devices showed no statistical difference (P>0.05), while heart rate measured by wireless wearable device was slightly lower (=−0.307±1.073, P<0.001), and the blood pressure (=1.259±5.354, P<0.001) and body temperature(=0.115±0.231, P<0.001) were slightly higher. The mean ratios of heart rate, respiratory rate, blood oxygen saturation, blood pressure and body temperature collected by the two devices were 0.996, 1.004, 1.000, 1.014, and 1.003, respectively. The 95% limits of agreement (LoA) and 95% confidence interval of 95%LoA of each indicator were within the clinically acceptable limit. The effective monitoring rate of each vital signs within 12 hours was above 98%. Conclusion The wireless wearable device has a high accuracy and reliability for continuous monitoring vital signs of patients after VATS for lung cancer, which provides a security guarantee for subsequent large-scale clinical application and further research.

Ethical Issues in the Application of IVF from the Perspective of Females Undergoing IVF / 中国医学伦理学

Infertile women experience complex biological and social experiences in the process of receiving IVF. From the perspective of females undergoing IVF, it is helpful to analyze the ethical and social problems that IVF may face more intuitively and concretely. In this study, 213 women who were undergoing IVF were randomly selected to carry out a questionnaire survey. The results showed that the choice of IVF for infertile women was driven by multiple pressures from family and society, not entirely on their own; They are not aware of the technology, but have a positive attitude, and are eager to be fully informed in the treatment process. In addition, the treatment brings great economic pressure to women who were undergoing IVF and has no significant impact on the relationship between husband and wife. Only by paying attention to the above problems and solving them can we benefit more infertile women and help them realize their reproductive wishes.

Discussion on the Continued Use of Assisted Reproductive Technology for Widowed Single Women / 中国医学伦理学

Assisted Reproductive Technology(ART) as a medical technology to treat infertility is gradually increasing the applications in domestic and foreign countries. In fact, some single women have birth demands for the application of ART in China. This paper described the reasons why some single women in China have demands for the application of ART, and analyzed the relevant legal, ethical and social issues that may be faced in the applying of technologies. Besides, the paper suggested that the using of ART in single women should be banned in principle, but for some widowed single women who lost their husbands during the process of ART, considering allowing them to complete the unfinished applications at their request. Meanwhile, a self-assessment mechanism should be established for these widowed single women, and ethical principles and managements should be strictly followed in the process of ART application to prevent the abuse of technology and fully protect the interests of offspring.

Small incision lenticule extraction for the treatment of myopic anisometropia / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the clinical effect of small incision lenticule extraction(SMILE)on the treatment of myopic anisometropia.METHODS: Clinical data of 76 patients(146 eyes)with myopic anisometropia who received SMILE or femtosecond assisted laser in situ keratomileusis(FS-LASIK)in our hospital from January 2021 to December 2022 were retrospectively analyzed. The patients were divided into SMILE group(39 cases, 77 eyes)and FS-LASIK group(37 cases, 69 eyes)according to surgical methods. Uncorrected visual acuity(UCVA), diopter, anisometropia, corneal aberration and occurrence of postoperative complications were compared between the two groups at 1 wk, 1 and 3 mo after surgery.RESULTS: The UCVA of the two groups was improved after surgery compared with that before surgery, and the coma, trefoil, spherical aberration and total higher-order aberration were significantly increased compared to those before surgery(P&#x003C;0.05), and the coma, trefoil, spherical aberration and total higher-order aberration in the FS-LASIK group were significantly higher than those in the SMILE group(P&#x003C;0.05). After follow-up to 3 mo after surgery, the incidence of postoperative complications was significantly lower in the SMILE group than that in the FS-LASIK group(5.2% vs 15.9%, P&#x003C;0.05).CONCLUSION: Both SMILE and FS-LASIK can effectively enhance the UCVA and improve the visual quality in patients with myopic anisometropia, but SMILE has lower corneal higher order aberrations, lower incidence of postoperative complications and better overall effect.

Relationship between influencing factors of operation time and postoperative complications in hand-assisted laparoscopic living donor nephrectomy / 器官移植

Objective To identify the influencing factors of operation time of hand-assisted laparoscopic living donor nephrectomy, and to analyze the relationship between influencing factors and the severity of postoperative complications. Methods Clinical data of 91 donors who underwent hand-assisted laparoscopic nephrectomy were retrospectively analyzed. The correlation between preoperative baseline data of donors and operation time was analyzed. The relationship between operation time and postoperative complications was assessed and the threshold of operation time was determined. Results Multiple donor renal arteries, thick perirenal and posterior renal fat, metabolic syndrome, high Mayo adhesive probability (MAP) score and Clavien-Dindo score prolonged the operation time. By analyzing the receiver operating characteristic (ROC) curve, we found that when the operation time was ≥138 min, the incidence of postoperative complications of donors was significantly increased (P<0.05). Conclusions For donors with multiple renal arteries, thick perirenal and posterior renal fat, metabolic syndrome and high MAP score and Clavien-Dindo score, experienced surgeons should be selected to make adequate preoperative preparation and pay close attention after surgery, so as to timely detect postoperative complications and reduce the severity of complications, enhance clinical prognosis of the donors.

Effects of femtosecond laser-assisted cataract surgery combined with intraocular lens implantation on postoperative deviation rate of multifocal intraocular lens and visual quality in cataract patients / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the effects of femtosecond laser-assisted cataract surgery combined with intraocular lens implantation(FLACS-IOL)on postoperative deviation rate of multifocal intraocular lens(MIOL)and visual quality in cataract patients.METHODS: In the prospective study, 95 patients with cataract(108 eyes)who underwent MIOL implantation in the hospital between January 2021 and December 2022 were enrolled. According to different surgical methods, they were divided into FLACS group(51 cases, 56 eyes)and Phaco group(44 cases, 52 eyes). The operation time, incision diameter of anterior capsule, effective phaco time(EPT), cumulative dissipated energy(CDE), uncorrected distance visual acuity(UCDVA), best corrected distance visual acuity(BCDVA), eccentricity distance of IOL and deviation rate at 3 mo after surgery, total high order aberration(HOA), Trefoil and coma under 3 mm pupil were compared between the two groups.RESULTS: The operation time in the FLACS group was significantly shorter than that in the Phaco group, EPT and CDE were significantly lower than those in the Phaco group(all P&#x003C;0.05). There was no significant difference in incision diameter of anterior capsule between the two groups(P&#x003E;0.05). At 1 wk, 3 mo after surgery, UCDVA in the FLACS group was better than that in the Phaco group(all P&#x003C;0.05). There were significant difference in UCDVA at 1 wk, 3 mo after surgery or BCDVA at 3 mo after surgery between the two groups(P&#x003C;0.05). At 3 mo after surgery, eccentricity distance of IOL in the FLACS group was shorter than that in the Phaco group, and deviation rate was significantly lower than that in the Phaco group(all P&#x003C;0.05). Under pupil diameter of 3 mm, HOA, trefoil and coma of whole eyes were decreased in both groups at 3 mo after surgery(P&#x003C;0.05). At 3 mo after surgery, there were significant differences in HOA and trefoil of whole eyes between the FLACS group and Phaco group(P&#x003C;0.05), but there was no significant difference in coma at 3 mo after surgery(P&#x003E;0.05).CONCLUSION: FLACS-IOL can effectively reduce deviation rate of IOL and obtain better visual quality in cataract patients.

Diagnosis and treatment of 131 adult patients with bronchopulmonary sequestration: A retrospective analysis / 中国胸心血管外科临床杂志

@#Objective    To explore the safety and feasibility of uni-portal video-assisted thoracic surgery (VATS) for the treatment of bronchopulmonary sequestration (BPS). Methods    The clinical data of BPS patients with surgical resection in Shanghai Pulmonary Hospital from February 2010 to June 2021 were reviewed. The patients were divided into a VATS group and a thoracotomy group according to the operation method. The operation time, intraoperative blood loss, hospital stay and postoperative complication rate were compared between the two groups. The VATS group was subdivided into a uni-portal VATS group and a multi-portal VATS group for subgroup analysis. Results    Finally 131 patients were enrolled, including 62 males and 69 females with an average age of 39.3±13.2 years. There were 103 patients in the VATS group and 28 patients in the thoracotomy group. A total of 104 patients were diagnosed with left lower BPS, 26 with right lower BPS and 1 with bilateral lower BPS. The main symptom was cough (88 patients, 67.2%). There were 119 patients diagnosed by thoracic enhanced CT before operation. Compared with the thoracotomy group, the operation time was not statistically different (P=0.717), but the blood loss was less, the rate of postoperative complication was lower and hospital stay was shorter in the VATS group (P<0.05). The rate of conversion to open surgery in the uni-portal VATS group and multi-portal VATS group was 11.8% and 13.5%, respectively. Meanwhile, patients in the uni-portal VATS group had shorter operation time and postoperative hospital stay, less blood loss and lower postoperative complication rate than those in the multi-portal VATS group (P<0.05). Conclusion     In order to improve the rate of diagnosis, the lung enhanced CT scan should be selected as an optimal noninvasive method in adult suspected patients (especially those with solid cystic and solid lesions in the lower lobe). Uni-portal VATS is a safe and feasible method for BPS which can be widely promoted.

Methods    A retrospective analysis was performed on patients who underwent thoracoscopic segmentectomy in the Department of Thoracic Surgery of Affiliated People's Hospital of Jiangsu University from June 2020 to December 2022. The patients who underwent preoperative 3D-CTBA using Materiaise's interactive medical image control system (Mimics) were selected as an observation group, and the patients who did not receive 3D-CTBA were selected as a control group. The relevant clinical indicators were compared between the two groups. Results    A total of 59 patients were included, including 29 males and 30 females, aged 25-79 years. There were 37 patients in the observation group, and 22 patients in the control group. The operation time (163.0±48.7 min vs. 188.8±43.0 min, P=0.044), intraoperative blood loss [10.0 (10.0, 20.0) mL vs. 20.0 (20.0, 35.0) mL, P<0.001], and preoperative puncture localization rate (5.4% vs. 31.8%, P=0.019) in the observation group were better than those in the control group. There was no statistically significant difference in the thoracic tube placement time, thoracic fluid drainage volume, number of intraoperative closure nail bin, postoperative hospital stay, or postoperative air leakage incidence (P>0.05) between the two groups. Conclusion    For patients who need to undergo anatomical pulmonary segmentectomy, using Mimics software to produce 3D-CTBA before surgery can help accurately identify pulmonary arteriovenous anatomy, reduce surgical time and intraoperative blood loss, help to determine the location of nodules and reduce invasive localization before surgery, and alleviate patients' pain, which is worthy of clinical promotion.

Corrective effect of femtosecond laser assisted laser in situ keratomileusis Xtra on patients with moderate to high myopia after 2a postoperatively / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To evaluate corrective effect and stability of corneal morphology in patients with moderate to high myopia after 2a treatment of femtosecond laser assisted laser in situ keratomileusis(FS-LASIK)Xtra.METHODS:Retrospective case-control study. A total of 30 cases(58 eyes)Patients with moderate to high myopia combined with astigmatism who planned to undergo refractive surgery in our hospital from August 2019 to August 2020 were included, and different types of surgery were performed respectively based on the relevant index of keratoconus screening in the preoperative corneal topography. They were divided into FS-LASIK group and Xtra group, with 15 cases(29 eyes)in each group. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), spherical equivalent(SE)and the corneal curvature of the anterior and posterior surfaces of different diameters(3, 5 and 7 mm)measured by Sirius three-dimensional corneal topography were observed preoperatively and 3 mo, 1 and 2 a postoperatively.RESULTS: The UCVA of the two groups of patients at different time points after surgery was significantly increased compared with preoperatively(both P&#x0026;#x003C;0.01), and there was no difference in UCVA and SE between the two groups(P&#x0026;#x003E;0.05). After 2 a postoperatively, residual astigmatism was -0.25-0 D in 25 eyes(86%)of the FS-LASIK Xtra group and 24 eyes(83%)of the FS-LASIK group. The actual corrected SE and expected corrected SE of both groups were positively correlated(both P&#x0026;#x003C;0.05). There were differences in corneal curvature on the surface of different diameter areas(3, 5, and 7 mm)between the two groups at 3 mo, 1, and 2 a postoperatively compared with preoperatively. After 1 and 2 a postoperatively, the corneal posterior surface curvature of the FS-LASIK Xtra group with corneal diameter of 3 and 5 mm was higher than that of the FS-LASIK group(P&#x0026;#x003C;0.05).CONCLUSIONS:FS-LASIK Xtra has good safety, efficacy and predictability in correcting patients with moderate to high myopia.

Staged Treatment with Chinese Herbal Medicine in a Controlled Ovarian Hyperstimulation of In Vitro Fertilization-Embryo Transfer Programme / 中医杂志

It is believed that kidney deficiency is the fundamental pathogenesis while liver constraint and spleen deficiency， and disharmony of chong （thorough vessel， 冲脉）and ren （conception vessel， 任脉） is the key pathogenesis of infertility patients who adopted controlled ovarian hyperstimulation of in vitro fertilization-embryo transfer （IVF-ET） programme. Therefore， the method of tonifying the kidneys dominantly and treating the liver and spleen simultaneously is proposed， and Chinese herbal medicine is suggested to be used in adjuvant treatment of staged IVF-ET controlled ovrian hyperstimulation. In the regulation stage， modified Liuwei Dihuang Pill （六味地黄丸） can be used to tonify kidney and supplement essence， fortify spleen and nourish liver； in the ovulation promotion stage， modified Wenjing Decoction （温经汤） should be used to warm kidney and assist yang， dispel stasis and nourish blood； in the pre-transplantation endothelial preparation stage， modified Shenling Baizhu Powder （参苓白术散） is suggested to fortify spleen and replenish qi， invigorate blood and resolve stasis； after the transplantation stage， modified Shoutai Pill （寿胎丸） or Taiyuan Decoction （胎元饮） can be taken to fortify spleen and tonify kidney， benefit qi and nourish blood.

Introgression of bacterial leaf blight (BLB) resistant gene, Xa7 into MARDI elite variety, MR219 by marker assisted backcrossing (MABC) approach / Introdução do gene resistente à ferragem da folha bacteriana (BLB), xa7 na variedade MARDI elite, MR219 por abordagem de backcrossing assistida por marcador (MABC)

Abstract Bacterial leaf blight (BLB) is one of the major rice diseases in Malaysia. This disease causes substantial yield loss as high as 70%. Development of rice varieties which inherited BLB resistant traits is a crucial approach to promote and sustain rice industry in Malaysia. Hence, this study aims were to enhance BLB disease resistant characters of high yielding commercial variety MR219 through backcross breeding approach with supporting tool of marker-assisted selection (MAS). Broad spectrum BLB resistance gene, Xa7 from donor parent IRBB7 were introgressed into the susceptible MR219 (recurrent parent) using two flanking markers ID7 and ID15. At BC3F4, we managed to generate 19 introgressed lines with homozygous Xa7 gene and showed resistant characteristics as donor parent when it was challenged with Xanthomonas oryzae pv. oryzae through artificial inoculation. Recurrent parent MR219 and control variety, MR263 were found to be severely infected by the disease. The improved lines exhibited similar morphological and yield performance characters as to the elite variety, MR219. Two lines, PB-2-107 and PB-2-34 were chosen to be potential lines because of their outstanding performances compared to parent, MR219. This study demonstrates a success story of MAS application in development of improved disease resistance lines of rice against BLB disease.

Resumo A mancha bacteriana das folhas (BLB) é uma das principais doenças do arroz na Malásia. Essa doença causa perdas substanciais de rendimento de até 70%. O desenvolvimento de variedades de arroz que herdaram características de resistência ao BLB é uma abordagem crucial para promover e sustentar a indústria do arroz na Malásia. Portanto, o objetivo deste estudo foi aumentar os caracteres BLB resistentes a doenças da variedade comercial MR219 de alto rendimento por meio de uma abordagem de cruzamento retrocruzamento com ferramenta de apoio de seleção assistida por marcador (MAS). O gene de resistência a BLB de amplo espectro, Xa7 do pai doador IRBB7, foi introgressado no MR219 suscetível (pai recorrente) usando dois marcadores flanqueadores ID7 e ID15. No BC3F4, conseguimos gerar 19 linhagens introgressadas com o gene Xa7 homozigoto e apresentamos características de resistência como genitor doador quando desafiado com Xanthomonas oryzae pv. oryzae por inoculação artificial. O pai recorrente MR219 e a variedade controle, MR263, estavam gravemente infectados pela doença. As linhas melhoradas exibiram características morfológicas e de desempenho de rendimento semelhantes às da variedade elite, MR219. Duas linhas, PB-2-107 e PB-2-34, foram escolhidas como linhas potenciais por causa de seus desempenhos excelentes em comparação com a mãe, MR219. Este estudo demonstra uma história de sucesso de aplicação de MAS no desenvolvimento de linhas de arroz melhoradas com resistência a doenças contra a doença BLB.
