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.

Daqinglong Decoction (DQLD), a traditional Chinese medicine (TCM) prescription firstly recorded in Shang han lun (the treatise on febrile diseases), has been used hundreds of years for the clinical treatment of influenza. However, the chemical composition and therapeutic mechanism of this prescription are unclear. UPLC-Q-TOF/MS was employed to analyze the chemical compounds in both methanol and boiling water extracts of DQLD. The compounds were then screened, characterized, and filtered using the TCMSP, TCMIP, TCM-ID and SymMap database, with a focus on their oral bioavailability and drug-likeness values. The resulting data were analyzed and optimized using the R language platform, Autodock and Gromacs software to identify biological processes and pathways. A total of 121 compounds were identified, of which 5 showed good binding ability to influenza virus targets (1L1B, IL10, CASP3, STAT3, TNF, and others). The active ingredient-target-influenza virus pathway was constructed using a network drug target analysis model prediction of DQLD, which was mainly enriched in Human cytomegalovirus infection, PI3K-Akt, HIF-1, and other signaling pathways through 1L1B, IL10 and other targets. Those pathways highly correlated to the body's inflammatory response, improve immunity, and exert anti-influenza virus effects. In summary, this study demonstrated that DQLD's active ingredients can effectively bind to influenza virus targets and exert anti-influenza virus effects by reducing inflammation and improving immunity through Human cytomegalovirus infection, PI3K-Akt and HIF-1 signaling pathways. These findings offer important insights into the potential mechanisms of action of DQLD and its potential use as a TCM against influenza and other viral infections.Communicated by Ramaswamy H. Sarma.
RESUMEN
BACKGROUND: Septicemia that leads to ocular involvement mostly presents as endophthalmitis or panophthalmitis. Contrarily, septicemia without intraocular involvement, known as hematogenous orbital cellulitis (HOC), involves only the orbit and is an extremely rare complication of septicemia and a rare type of orbital cellulitis. CASE PRESENTATION: Four male patients with septicemia presented with orbital involvement without intraocular infection were described in this study. They were 22 (case 1), 15 (case 2), 79 (case 3), and 30 (case 4) years old, with a mean age of 29.75 years. All patients were immunocompromised except for case 2. Cases 1 and 3 had a history of steroid use, whereas case 4 was in a post-chemotherapy myelosuppression phase. Septicemia in case 1 was community-acquired, cases 3 and 4 were hospital-acquired, and case 2 was secondary to acne squeezing. Blood cultures from cases 1, 2, and 3 were positive for Candida albicans, methicillin-resistant Staphylococcus aureus, and Klebsiella pneumoniae, respectively. Case 4 had negative cultures; however, next-generation sequencing reported the presence of Enterococcus faecalis and Rhizopus oryzae. Case 1 had right eye involvement, and both eyes were involved in the other three cases. According to Chandler's classification, case 1 was type 2, case 2 was type 2 (OD) and type 4 (OS), and cases 3 and 4 were type 1 orbital infections. All patients had eyelids erythema, and cases 1 and 2 had mildly decreased visual acuity, proptosis, and painful and restricted ocular motility. Hospital stays ranged from 13 to 43 days (mean, 24 days). All patients received systemic antibiotic therapy based on drug sensitivity and next-generation sequencing results, in combination with multidisciplinary treatment, resulting in complete recovery of ocular and systemic signs and symptoms; no ocular surgical interventions were performed. Extraocular muscle palsy was the last symptom to resolve. CONCLUSION: HOC is predominantly seen in immunocompromised individuals with a high proportion of hospital-acquired infections and positive cultures for pathogens. Infection control using systemic antibiotics targeted at the causative organism guarantees a favorable prognosis.

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: 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.

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.

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.

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 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.

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.

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).

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
Skeletal undifferentiated pleomorphic sarcoma (SUPS) is an invasive pleomorphic soft tissue sarcoma with a high degree of malignancy and poor prognosis. It is prone to recur and metastasize. The tumor microenvironment (TME) and the pathophysiology of SUPS are barely described. Single-cell RNA sequencing (scRNA-seq) provides an opportunity to dissect the landscape of human diseases at an unprecedented resolution, particularly in diseases lacking animal models, such as SUPS. We performed scRNA-seq to analyze tumor tissues and paracancer tissues from a SUPS patient. We identified the cell types and the corresponding marker genes in this SUPS case. We further showed that CD8+ exhausted T cells and Tregs highly expressed PDCD1, CTLA4 and TIGIT. Thus, PDCD1, CTLA4 and TIGIT were identified as potential targets in this case. We applied copy number karyotyping of aneuploid tumors (CopyKAT) to distinguish malignant cells from normal cells in fibroblasts. Our study identified eight malignant fibroblast subsets in SUPS with distinct gene expression profiles. C1-malignant Fibroblast and C6-malignant Fibroblast in the TME play crucial roles in tumor growth, angiogenesis, metastasis and immune response. Hence, targeting malignant fibroblasts could represent a potential strategy for this SUPS therapy. Intervention via tirelizumab enabled disease control, and immune checkpoint inhibitors (ICIs) of PD-1 may be considered as the first-line option in patients with SUPS. Taken together, scRNA-seq analyses provided a powerful basis for this SUPS treatment, improved our understanding of complex human diseases, and may afforded an alternative approach for personalized medicine in the future.

RATIONALE: Phacolytic glaucoma is a rare complication induced by hypermature cataracts and may occasionally be encountered in some rural areas. It tends to be misdiagnosed and induces a risk of permanent vision impairment. PATIENT CONCERNS: A 63-year-old Uighur woman complained of redness and decreased vision in her right eye and was treated for endophthalmitis at a primary hospital before being referred to our hospital. DIAGNOSIS: On admission, the patient had weak light perception in the right eye, an intraocular pressure of 65 mmHg, and slit-lamp examination revealed swelling of the eyelids and significant injection of conjunctiva. The entire cornea was cloudy and edematous, whereas the aqueous humor was milky turbid. Cytological examination of the aqueous liquid confirmed the presence of lens protein-laden macrophages. A Morgagnian cataract was observed after anterior chamber irrigation. So the final diagnosis was phacolytic glaucoma. INTERVENTIONS: The patient received anterior chamber irrigation and extracapsular cataract extraction with intraocular lens implantation successively. OUTCOMES: Final visual acuity was limited to 6/120 due to secondary optic nerve damage. LESSONS: Phacolytic glaucoma can mimic endophthalmitis and tend to be misdiagnosed, causing permanent vision impairment. Improving awareness of phacolytic glaucoma and enhancing public health education regarding cataracts are ways to prevent phacolytic glaucoma and phacolytic glaucoma-related vision loss.

The development of traditional Chinese medicine(TCM) has always been highly valued and supported since 1949. However, Chinese medicine industry still faces great challenges in view of the current status of the industry and registration and approval of new products in recent years. Related policies also directly influence the development of the industry. The latest version of the Provisions for Drug Registration and Requirement on Registration Classification and Application Information of Traditional Chinese Medicines have been put into practice since 2020. Registration classification is the core content of the Chinese medicine registration management system, as it is closely related to the research, development, and registration of Chinese medicine and the innovative development of the industry. This article aims to systematically review the historical evolution of the category of Chinese medicine registration and analyze the current status and problems, which is expected to provide a reference for the formulation of supporting documents according to related laws and regulations.

Since the implementation of drug registration in China, the classification of Chinese medicine has greatly met the needs of public health and effectively guided the transformation, inheritance, and innovation of research achievements on traditional Chinese medicine(TCM). In the past 30 years, the development of new Chinese medicine has followed the registration transformation model of " one prescription for single drug". This model refers to the R&D and registration system of modern drugs, and approximates to the " law-abiding" medication method in TCM clinic, while it rarely reflects the sequential therapy of syndrome differentiation and comprehensive treatment with multiple measures. In 2017, Opinions on Deepening the Reform of Review and Approval System and Encouraging the Innovation of Drugs and Medical Devices released by the General Office of the CPC Central Committee and the General Office of the State Council pointed out that it is necessary to " establish and improve the registration and technical evaluation system in line with the characteristics of Chinese medicine, and handle the relationship between the traditional advantages of Chinese medicine and the requirements of modern drug research". Therefore, based on the development law and characteristics of TCM, clinical thinking should be highlighted in the current technical requirements and registration system of research and development of Chinese medicine. Based on the current situation of registration supervision of Chinese medicine and the modern drug research in China, the present study analyzed limitations and deficiency of " one prescription for single drug" in the research and development of Chinese medicine. Additionally, a new type of " series prescriptions" was proposed, which was consistent with clinical thinking and clinical reality. This study is expected to contribute to the independent innovation and high-quality development of the TCM industry.
