RESUMEN
Bone disease is a common complication following liver transplantation, often overlooked in clinical practice. Clinical diagnosis of post-liver transplantation bone disease is challenging, and there have been few case report in the literature. This case report presents a patient who underwent two liver transplant surgeries, exhibited good daily activity, and did not display typical clinical symptoms such as fatigue, bone pain, or spinal deformities associated with prolonged sitting or standing. However, within the fifth year after the second liver transplant, the patient experienced two consecutive fractures. In March 2023, the patient underwent the first bone density test, which revealed osteoporosis. This case highlights the fact that severe fractures after liver transplantation may not necessarily be accompanied by typical symptoms of bone disease. Without timely examination and early prevention, serious consequences may arise. Therefore, this condition requires attention, proactive prevention, early detection, and timely treatment. Additionally, a retrospective analysis of the patient's previous laboratory data revealed persistent abnormalities in serum markers such as hypocalcemia and elevated alkaline phosphatase levels after liver transplantation, emphasizing the importance of monitoring these serum markers.

OBJECTIVES@#To study the role and mechanism of platelet-derived growth factor BB (PDGF-BB) on platelet production in Kawasaki disease (KD) mice and human megakaryocytic Dami cells through in vitro and invivo experiments.@*METHODS@#ELISA was used to measure the expression of PDGF in the serum of 40 children with KD and 40 healthy children. C57BL/6 mice were used to establish a model of KD and were then randomly divided into a normal group, a KD group, and an imatinib group (30 mice in each group). Routine blood test was performed for each group, and the expression of PDGF-BB, megakaryocyte colony forming unit (CFU-MK), and the megakaryocyte marker CD41 were measured. CCK-8, flow cytometry, quantitative real-time PCR, and Western blot were used to analyze the role and mechanism of PDGF-BB in platelet production in Dami cells.@*RESULTS@#PDGF-BB was highly expressed in the serum of KD children (P<0.001). The KD group had a higher expression level of PDGF-BB in serum (P<0.05) and significant increases in the expression of CFU-MK and CD41 (P<0.001), and the imatinib group had significant reductions in the expression of CFU-MK and CD41 (P<0.001). In vitro experiments showed that PDGF-BB promoted Dami cell proliferation, platelet production, mRNA expression of PDGFR-β, and protein expression of p-Akt (P<0.05). Compared with the PDGF-BB group, the combination group (PDGF-BB 25 ng/mL + imatinib 20 μmol/L) had significantly lower levels of platelet production, mRNA expression of PDGFR-β, and protein expression of p-Akt (P<0.05).@*CONCLUSIONS@#PDGF-BB may promote megakaryocyte proliferation, differentiation, and platelet production by binding to PDGFR-β and activating the PI3K/Akt pathway, and the PDGFR-β inhibitor imatinib can reduce platelet production, which provides a new strategy for the treatment of thrombocytosis in KD.

OBJECTIVE@#To compare the clinical efficacy of acupuncture with different frequencies in the treatment of patients with functional dyspepsia (FD).@*METHODS@#A total of 90 patients with FD were randomly divided into a 3-time acupuncture treatment per week group (3-A group, 31 cases, 2 cases dropped off), a 1-time acupuncture treatment per week group (1-A group, 30 cases, 2 cases dropped off) and a control group (29 cases, 2 cases dropped off). In the two acupuncture groups, the acupoints were Zhongwan (CV 12) and bilateral Tianshu (ST 25), Neiguan (PC 6), Liangqiu (ST 34), Yanglingquan (GB 34), Zusanli (ST 36) and Taichong (LR 3), stimulated 3 times a week and once a week, respectively; and the treatment was given consecutively for 4 weeks. In the control group, no intervention was adopted, but the compensatory therapy was provided after the end of follow-up. The scores of the symptom index of dyspepsia (SID), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were compared among the 3 groups before treatment, after 4 weeks of treatment and in 4 and 8 weeks after treatment completion separately. The score of Nepean dyspepsia life quality index (NDLQI) was evaluated before treatment, after 2 and 4 weeks of treatment and in 4 and 8 weeks after treatment completion.@*RESULTS@#After 4 weeks of treatment and in 4 and 8 weeks after treatment completion, the scores of SID, SAS and SDS were all reduced in the 3-A group and the 1-A group when compared with the scores before treatment (P<0.000 1, P<0.05). After 4 weeks of treatment, the scores of SID, SAS and SDS in the two acupuncture groups were lower than those in the control group (P<0.000 1). After 2 and 4 weeks of treatment, the increased values of NDLQI score in the two acupuncture groups were all higher than those in the control group (P<0.05). In 4 and 8 weeks after treatment completion, the scores of SID, SAS and SDS in the 3-A group were lower than those in the 1-A group (P<0.001, P<0.05), and the increased values of NDLQI score in the 3-A group were higher than those in the 1-A group (P<0.000 1).@*CONCLUSION@#Acupuncture given 3 times per week is superior to the treatment given once per week in the aspects of relieving the clinical symptoms, improving the quality of life and regulating the emotional state in patients with FD. This efficacy is persistent for 8 weeks after treatment completion.

The toxic pathogen theory, an important part of the theories of traditional Chinese medicine(TCM), began in the Qin and Han dynasties, formed in the Jin, Sui, Tang, and Song dynasties, developed rapidly in the Ming and Qing dynasties, and conti-nued to develop in contemporary times based on the achievements of its predecessors. The continuous exploration, practice, and inheri-tance of many medical practitioners over the generations have facilitated the enrichment of its connotation. The toxic pathogen is violent, fierce, dangerous, prolonged, rapid in transmission, easy to hurt the internal organs, hidden, and latent, with many changes, and it is closely related to the development of tumor diseases. TCM has a history of thousands of years in the prevention and treatment of tumor diseases. It is gradually realized that the etiology of tumor is mainly attributed to the deficiency of healthy Qi and excess of to-xic pathogen, and the struggle between healthy Qi and toxic pathogen runs through the whole course of tumor, with the deficiency of healthy Qi as the prerequisite and the invasion of toxic pathogen as the root of the occurrence. The toxic pathogen has a strong carcinogenic effect and is involved in the whole process of tumor development, which is closely related to the malignant behaviors of tumors, including proliferation, invasion, and metastasis. This study discussed the historical origin and modern interpretation of the toxic pathogen theory in the prevention and treatment of tumors, with aims of sorting out the theoretical system based on the toxic pathogen theory in the treatment of tumor diseases, and illustrating the importance of the toxic pathogen theory in the treatment of tumors in the context of modern research on pharmacological mechanisms and the development and marketing of relevant anti-tumor Chinese medicinal preparations.

Objective:To investigate and summarize the early management experience of 22 patients with end-stage heart failure(ESHF) who underwent left ventricular assist device(LVAD) implantation in an intensive care unit(ICU) in a single center.Methods:Data of 22 patients with ESHF treated with LVAD in the ICU of TEDA International Cardiovascular Hospital from September 2020 to August 2022 were retrospectively analyzed. There were 16 males and 6 females, aged from 20 to 67 years old, with a mean age of(51.0±13.3)years old. There were 21 cases with dilated cardiomyopathy, 1 case with ischemic cardiomyopathy, 6 cases with tricuspid regurgitation, 1 case with intra-aortic balloon pump for cardiogenic shock, and 5 cases with cardiac resynchronization therapy for arrhythmia. After the operation, all patients received restricted fluid therapy, a " stepwise" anticoagulation strategy, and strict blood pressure management. The postoperative complications and treatment process were reviewed, the treatment and management experience were summarized, and the prognosis of the patients was statistically analyzed.Results:All 22 patients survived within 90 days after surgery, and 21 patients(95.5%) recovered well, the pump works fine and there was no hemolysis and thrombosis of LVAD. Major complications included: 1 case of severe pneumonia(4.5%), 2 cases of pericardial tamponade(9.1%), 1 case of intracerebral hemorrhage(4.5%), 1 case of mediastinal infection(4.5%), 5 cases of positive occult blood in gastric juice(22.7%), no cases of right ventricular failure、aortic insufficiency and cerebral infarction. The duration of postoperative mechanical ventilation was 17(8.5, 51.5) h, and the ICU stay was 14(10, 27) days.Conclusion:LVAD is another effective treatment for patients with ESHF in addition to heart transplantation. Good postoperative blood pressure control, " stepwise" anticoagulation strategy and " restrictive" fluid management can reduce postoperative complications in the early phase of post-operation, which is crucial for the prognosis of patients with LVAD.
RESUMEN
OBJECTIVE@#To observe the effect of acupuncture at "Feishu" (BL 13) + "Dingchuan" (EX-B 1) and "Kongzui" (LU 6) + "Yuji" (LU 10) for the airway remodeling in asthma rats based on the transforming growth factor-β1 (TGF-β1)/ Smad family member 3 (Smad3) signaling pathway; and explore the efficacy difference between the two acupoint combinations.@*METHODS@#Forty SPF male SD rats, aged 4 weeks, were randomly divided into a blank group (n = 10) and a modeling group (n = 30). The ovalbumin (OVA) sensitization method was used to establish asthma model in the modeling group. After successful model preparation, the rats of the modeling group were randomized into a model group, an acupuncture at "Feishu" (BL 13) + "Dingchuan" (EX-B 1) (AAF) group, and acupuncture at "Kongzui" (LU 6)+"Yuji" (LU 10) (AAK) group, with 10 rats in each one. Starting from day 15 of the experiment, 5 min after motivating, acupuncture was applied to "Feishu" (BL 13) + "Dingchuan" (EX-B 1) and "Kongzui" (LU 6)+"Yuji" (LU 10) in the AAF group and the AAK group respectively. The intervention was delivered for 30 min each time, once daily, lasting 3 weeks consecutively. Using lung function detector, the airway resistance (RL) and dynamic compliance (Cdyn) of the lungs were detected. The histomorphology of lung tissues was detected with HE staining and Masson staining, and the mRNA and protein expression of TGF-β1 and Smad3 in lung tissues was detected with the real-time PCR and Western blot methods.@*RESULTS@#Compared with the blank group, RL was increased and Cdyn was decreased in the rats of the model group (P<0.01); and RL was reduced and Cdyn was increased in the AAF group and the AAK group when compared with those in the model group (P<0.01, P<0.05). The rats of the model group had bronchial lumen stenosis, inflammatory cell infiltration, collagen fibre hyperplasia and thickened smooth muscle in the lung tissues when compared with those in the blank group; and in comparison with the model group, all of the above morphological changes were attenuated in the AAF group and the AAK group. Besides, these morphological changes of the lung tissues were more alleviated in the AAF group when compared with those in the AAK group. In comparison with the blank group, the mRNA and protein expression of TGF-β1 and Smad3 of the lung tissues was increased in the model group (P<0.01), and it was reduced in the AAF group and the AAK group when compared with that in the model group (P<0.05, P<0.01). The mRNA expression of TGF-β1 and Smad3 was lower in the AAF group when compared with that in the AAK group (P<0.05).@*CONCLUSION@#Acupuncture at either "Feishu" (BL 13)+"Dingchuan" (EX-B 1) or "Kongzui" (LU 6)+"Yuji" (LU 10) reduces the airway remodeling in the rats with asthma, which may be related to the down-regulation of mRNA and protein expression of TGF-β1 and Smad3. The better efficacy is obtained with acupuncture at "Feishu" (BL 13)+"Dingchuan" (EX-B 1).

Ethnic medicine has a rich history of application. Because of the large number of ethnic groups, wide geographical distribution, and unique medical systems in China, the research on the human use experience(HUE) of ethnic medicine should combine the characteristics of ethnic medicine, be based on practical experience, and respect folk practice and tradition. The clinical positioning of ethnic medicine should consider three factors, i.e., population region, dominant diseases, and clinical demand. We should consider the development of traditional preparations that meet the needs of ethnic regions and encourage the development of new drugs that can be popularized and used nationwide for the dominant diseases of ethnic medicines. Attention should be paid to the problems such as a large number of customary articles or substitutes of ethnic medicinal materials, the phenomena of foreign bodies with the same name and different names for the same substance, the different standards of medicinal materials, and the poor processing standards. The name, processing method, source, medicinal parts, and dosage of ethnic medicinal materials or decoction pieces should be determined, and resources should be carefully evaluated to ensure the safety of medicinal resources and ecology. The preparation of ethnic medicine is mostly in the form of pills, powder, ointment, etc., with simple processing technology. The problems of low-quality stan-dards of some preparations, different prescriptions with the same name, and inconsistent processing technology should be overcome, and the process route and main process parameters should be clarified to lay the foundation for the subsequent empirical research on HUE. In the collection and analysis of the HUE data of ethnic medicine, the core guiding ideology of "patient-centered" should be established, and the experience data of patients should be collected. The problems of weak links existing in the inheritance of ethnic medicine should be solved, and flexible and diverse methods should be adopted. Meanwhile, on the premise of complying with the requirements of the principles of medical ethics, we should respect the religion, culture, and customs of ethnic areas to obtain the key HUE information of ethnic medicine. On the basis of the patient preference information and differences in regional disease epidemiology, population characteristics, and medical practice, whether the HUE conclusions of ethnic medicine can be extrapolated to patients outside the region is evaluated from the aspects of clinical benefits, risk tolerance, risk acceptance, etc. The HUE research on ethnic medicine is carried out in a clear way to guide the research and development of new ethnic medicines.

ObjectiveTo investigate whether there exists gender differences in mechanical pain hypersensitivity induced by the subcutaneous injection of macrophage colony-stimulating factor (M-CSF) in normal mice and to explore the preliminary mechanism. MethodsThirty 10-week-old C57BL/6J mice were randomly divided into three groups, (n = 10 mice/group, half male and half female). The albumin control group (BSA, 0.3 μg), low dose M-CSF group (L M-CSF, 0.075 μg) and high dose M-CSF group (H M-CSF, 0.3 μg) received 50 μL BSA or M-CSF injected subcutaneously into the left medial thigh once daily for 3 consecutive days. Before and after drug administration, von-Frey mechanical sensitivity test was used to detect the mechanical paw withdrawal threshold (PWT) in each group. Immunofluorescence was performed to examine the expression changes of Ionized calcium-binding adaptor molecule 1 (Iba1) in skin, calcitonin gene-related peptide (CGRP) and phosphorylated ERK1/2 (p-ERK) in L5-L6 DRG and lumbar spinal dorsal horn. ResultsIn female mice, only high dose of M-CSF caused mechanical allodynia, whereas in male mice both doses produced marked allodynia. Mechanically, high-dose M-CSF induced massive aggregation of subcutaneous macrophages (marked by Iba1) in male and female mice, but more dramatic dependence in female mice. Similar gender differences were also found in the increase of p-ERK and CGRP expression in dorsal root ganglion (DRGs). Notably, CGRP expression was especially elevated in the fibers of DRG in male mice. Correspondingly, the expressions of p-ERK and CGRP+ terminals in the superficial spinal dorsal horn of male mice were significantly higher than those of female mice after M-CSF treatment. ConclusionSubcutaneous injection of M-CSF triggers sexual dimorphism in mechanical pain hypersensitivity, which is related with differential changes in peripheral macrophage expansion and sensitization of the nociceptive pathway.
RESUMEN
Objective:To establish the first Mini-Formative Evaluation of Radiation Oncology (Mini-FERO) scale in China and evaluate its preliminary application value in the standardized training for radiation oncology resident physicians.Methods:Based on the educational curriculum and examination requirements for the standardized training for radiation oncology resident physicians, as well as the standardized Mini-Clinical Evaluation Exercise (Mini-CEX) scale commonly used in clinical practice, the Mini-Formative Evaluation of Radiation Oncology (Mini-FERO) scale was developed to facilitate the standardized training for resident physicians in the field of radiation oncology. In this prospective study, a randomization method using a random number table was employed to select a cohort of 26 resident physicians who completed their rotations in Department of Radiation Oncology at the Cancer Hospital, Chinese Academy of Medical Sciences from March 1, 2021 to December 31, 2021. The Mini-FERO scale was administered in the initial, middle, and final stages during the rotation period. The differences in evaluation scores before and after the assessments were analyzed by paired t-test. Furthermore, participating resident physicians and supervising teachers provided satisfaction ratings, and a comprehensive evaluation of the Mini-FERO scale was conducted. Results:The average scores of the three examinations of 26 resident physicians demonstrated a successive improvement, with individual performance in each assessed category also showing progressive enhancement. The second evaluation exhibited a more pronounced score increase compared to the first evaluation, with a mean improvement of (1.43±1.02) points ( t=7.13, P<0.001); while the third evaluation had a mean improvement of (0.41±0.50) points ( t=4.07, P<0.001) compaired to the second evaluation, with a mean difference of (1.02±1.15) points between the two ( t=4.53, P<0.001). The average time required for the assessments was (34.31±24.46) min. Overall satisfaction ratings from the evaluated resident physicians for the Mini-FERO scale were (8.42±0.85) points, and supervising teachers reported an overall satisfaction rating of (8.45±0.85) points. The satisfaction rate was 96% (25/26). Conclusions:In this study, the Mini-FERO scale was successfully developed and validated in the context of clinical teaching practice for radiation oncology resident physicians. The Mini-FERO scale is proven to be a feasible tool for assessing the gradual improvement of resident physicians throughout their learning process in the field of radiation oncology. Importantly, it offers the advantages of short assessment time, thereby avoiding additional burden on supervising teachers. The adoption of the Mini-FERO scale addresses current limitations of lacking of formative evaluation in the standardized training for radiation oncology resident physicians.
RESUMEN
In recent years,with the change in lifestyle and social environment and the increase in pressure in both life and work,male fertility has decreased significantly in China,and the incidence of male infertility has increased year by year,which has brought great challenges to andrologists. Traditional Chinese medicine (TCM) has a definite curative effect in the treatment of male infertility and is widely applied in clinical practice. In order to clarify the role of TCM in different types and each stage of male infertility,the China Association of Chinese Medicine (CACM) invited outstanding young andrologists in the clinic of TCM and western medicine to discuss topics such as idiopathic oligospermia and teratospermia,abnormal semen liquefaction,varicocele,immune infertility,improving success ratio of assisted reproductive technology,and ameliorating depression or anxiety. They conducted in-depth discussions on the advantages,characteristics,disadvantages,diseases responding specifically,and advantageous aspects of TCM treatment. The causes of male infertility and related links of treatment were summarized. Due to the unclear etiology and complex pathogenesis of male infertility,western medicine cannot achieve a good curative effect,while TCM,taking the holistic view as the core,specializes in improving functional diseases and can correspond to multiple targets and factors,with comprehensive treatments such as internal treatment and external treatment. This study summarized the advantageous diseases and advantageous stages of TCM treatment alone and integrated TCM and western medicine treatment and put forward suggestions for the treatment of the diseases by TCM and western medicine in order to promote the therapeutic effects and advantages of TCM among andrologists,increase mutual learning and communication between TCM and western physicians,provide patients with excellent and personalized treatment plans in clinical practice,and improve the curative effect of male infertility and fertility of males in China.
RESUMEN
Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions. The professional guideline is required to guide the standardized and efficient clinical comprehensive evaluation of Chinese patent medicine and further improve the authority and quality of evaluation. In combination with the characteristics of Chinese patent medicine and the latest research achievement at home and abroad,the detailed specifications were formulated from six aspects including design,theme selection,content and index,outcome,application and appraisal,and quality control. The guideline was developed based on the guideline development requirements of China Assoication of Chinese medicine. After several rounds of expert consensus and public consultation,the current version of the guideline has been developed.

Lateral pelvic lymph node (LPLN) metastasis is a poor prognostic factor for rectal cancer, which is more common in low site, T 3-T 4 stage, and positive lymph nodes in mesorectum. However, there is no accurate predictor of metastasis. At present, high-resolution MRI is the optimal diagnosis of LPLN metastasis, but the threshold value is still unclear. The treatment mode of LPLN metastasis in locally advanced rectal cancer is controversial worldwide. European and American countries advocate chemoradiotherapy combined with total mesorectal resection, while Japan recommends total mesorectal resection combined with LPLN dissection. The combination of radiotherapy and surgery could achieve good local control. Further more, by using the information of lateral lymph nodes before and after radiotherapy, patients with high risk can be screened for intensive treatment, such as LPLN dissection or dose-escalation approaches. Currently, there is still a lack of high-quality evidence on the efficacy of various approaches in the treatment of LPLN metastasis, and more research is needed to improve the treatment strategies.

In recent years, with the development of rectal cancer treatment mode, the anal preservation rate in rectal cancer patients has been gradually increased. In addition to preserving the anal shape, the preservation of anal function is also gradually valued. In this article, literature review on anal function related to radiotherapy and chemotherapy for rectal cancer patients was conducted, aiming to elaborate the evaluation criteria and research status of anal function in rectal cancer patients.
RESUMEN
Neoadjuvant chemoradiotherapy combined with total mesorectal excision is the standard treatment for stage T 3-T 4/N+ locally advanced rectal cancer (LARC). However, proctectomy is burdened with consistent postoperative morbidity, severely affecting the quality of life. "Organ preserving" methods could achieve similar oncological outcomes in highly selected patients whose tumors demonstrate (almost) clinical complete response to neoadjuvant treatment, while maintaining the quality of life and anorectal function by keeping the anus.

To clarify the research progress and existing problems in the clinical research on oral Chinese patent medicine in the treatment of breast cancer. National drug catalogs and databases were searched for oral Chinese patent medicines against breast cancer. Chinese and English databases were searched for clinical trials on oral Chinese patent medicines in the treatment of breast cancer. The main functions,drug composition,literature basic characteristics,intervention measures, and outcome indicators of Chinese patent medicines were comprehensively analyzed and evaluated by a scoping review based on visual charts. In 68 Chinese patent medicines included,53% of them were potent in activating blood, resolving stasis, tonifying the kidney, and strengthening the spleen. In terms of frequency, the top drugs were Ligustri Lucidi Fructus, Astragali Radix, Moutan Cortex, Poria, and Olibanum,indicating the importance of the therapeutic principles of activating blood, resolving stasis, tonifying the kidney, and strengthening the spleen for breast cancer treatment. In 161 included clinical trials,70.71% of the intervention measures were Chinese patent medicine combined with chemotherapy. Literature studies mainly reported Xihuang pills and Huaier granules,which may be related to the combination of chemotherapy and the inclusion in the medical insurance. The outcome evaluation was mainly based on immune indexes,tumor markers,Karnofsky score,safety report and objective response rate,while the survival time and characteristic outcome indicators of traditional Chinese medicine (TCM) were insufficient. The application and research on oral Chinese patent medicine in the treatment of breast cancer have advanced in recent years,but most of the clinical research evidence is not robust,and the evaluation of outcome indicators is not standardized,which needs to be improved.
RESUMEN
Objective:To investigate and evaluate the efficacy of HeartCon left ventricular assist device (LVAD) in the treatment of adult patients with end-stage heart failure (ESHF).Methods:A prospective and observational study was conducted. Patients with ESHF who underwent LVAD implantation in the department of cardiac surgery of Teda International Cardiovascular Hospital from September 2020 to August 2021 were selected. The left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), New York Heart Association (NYHA) classification, N-terminal pro-B type natriuretic peptide (NT-proBNP), and six minute walk distance (6MWD) before operation and 90 days after operation were compared. The incidence of equipment failures and major adverse events within 90 days after operation were recorded.Results:A total of 20 patients with ESHF were included, with 15 males and 5 females. Patients' age ranged from 20 to 67 years old, with an average of (50.2±13.6) years old. The range of body weight was 49.8-106.1 kg, with an average of (67.9±15.5) kg, and the body surface area (BSA) was from 1.49 to 2.32 m 2, with an average of (17.6±0.22) m 2. The operation process of all the patients were successful. The length of hospital stay ranged from 33 to 90 days, and the average was 56.0 (42.8, 75.0) days. Complications within 90 days after operation as follows, 2 cases with pericardial tamponade (10%), 1 case with cerebral hemorrhage (5%), 1 case with mediastinum infection (5%), 3 cases with acute renal injury (AKI, 15%), 5 cases with gastrointestinal bleeding (25%). There were no mechanical failure of LVAD and hemolysis events, right ventricular failure (RVF), cerebral infarction and death occurred. Compared with preoperative, the LVEDD significantly decreased (mm: 67.50±13.98 vs. 77.40±9.73), LVEF significantly increased (%: 34.80±9.76 vs. 22.70±5.62), NT-proBNP significantly decreased (ng/L: 2 028.65±1 752.05 vs. 4 796.45±4 355.40), 6MWD significantly increased (m: 385.20±144.12 vs. 85.81±63.50) at 90 days after operation, and the differences were statistically significant (all P < 0.05). 18 cases (90%) of the 20 patients reached NYHA classification Ⅰ and 2 cases (10%) reached NYHA classification Ⅱ, which were significantly improved compared with those before surgery (all patients' NYHA classification were Ⅳ before surgery). Conclusion:HeartCon LVAD can effectively improve the life quality of patients with ESHF, which has been proved safe and effective in clinical trials, but its long-term effects and complications need further observation and study.
