Based on the pathogenesis of erectile dysfunction (ED) from the meridian-zangfu relationship and the "brain-heart-kidney-essence chamber" axis, it proposes that dysfunction of the "brain-heart-kidney-essence chamber" axis is closely related to the occurrence of ED. Among these, brain-heart disharmony is the key pathogenic factor, kidney deficiency and essence depletion constitute an important basis, and essence chamber stasis is a critical mechanism. The treatment approach emphasizes harmonizing the brain and heart, regulating the mind, tonifying the kidney and replenishing qi, unblocking qi and blood to harmonize the essence chamber. The primary acupoints include Baihui (GV20)-Neiguan (PC6)-Shenmen (HT7), Taixi (KI3)-Guanyuan (CV4)-Sanyinjiao (SP6), and Zhongji (CV3)-Dahe (KI12)-Gongsun (SP4), with additional acupoints selected based on syndrome differentiation. This approach aims to restore the clarity of the brain and heart, replenish kidney qi, and unblock the essence chamber, thereby facilitating the restoration of normal functions of the brain, heart, kidney, and essence chamber, and alleviating ED symptoms and improving overall clinical efficacy.

Sarcomatoid carcinoma is an uncommon malignancy, and its occurrence in the penis is even rarer. This paper reports a case of primary sarcomatoid carcinoma of the penis. The patient was admitted to the hospital with a mass on the glans penis with ulceration, and underwent partial penectomy, and the postoperative pathology confirmed the diagnosis of sarcomatoid carcinoma. One month after surgery, lower abdominal ultrasound and MRI showed abnormal enlargement of bilateral inguinal area and pelvic lymph nodes, respectively. PET/CT scan showed multiple lymph node metastases in retroperitoneum, pelvis, and inguinal area. The patient was recommended chemotherapy, which was refused by the patient and his family. At 9-month postoperative follow-up, there was no recurrence of the penile stump and no deterioration of the condition.

Based on the"brain-heart-kidney-seminal chamber"axis theory to understand the pathogenesis of coronary heart disease(CHD)complicated with erectile dysfunction(ED),it is considered that the dysfunction of the"brain-heart-kidney-seminal chamber"axis is closely related to the occurrence of CHD complicated with ED,in which kidney deficiency is the initial factor;heart brain disorder,loss of consciousness is the key to the pathogenesis;the loss of seminal chamber is an important link in the pathogenesis.Under the guidance of the concept of"brain-heart-kidney-seminal chamber"axis,Cistanches Herba-Rehmannize Radix et Praeparata-Cuscutae Semen were used to invigorate the kidney and regulate the essence of the brain,heart,kidney and seminal chamber;Salviea Miltiorrhizae Radix et Rhizoma-Chuanxiong Rhizoma-Schisandrae Chinensis Fructus can reach the heart and brain,calm the heart and calm the mind;Cyathulae Radix-Scolopendra-Spatholobi Caulis can adjust and restore the seminal chamber,moistening the tendons and vibrating the flaccidity.In clinical practice,the whole medication should be used to make the brain,heart and kidney in harmony with the seminal chamber at the same time,and the drugs should be flexibly added and subtracted according to the specific symptoms of patients to enhance the curative effect of CHD patients with ED.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

OBJECTIVES: To investigate the effect of adriamycin (ADM), idelalisib or ADM and their combination on cell proliferation and intracellular concentration of ADM, and to explore the reversal effect of idelalisib on drug resistance to ADM. METHODS: The K562 and K562/ADM cells were respectively treated with ADM and idelalisib at different concentrations. The 50% inhibitory concentration (IC RESULTS: The cell survival rates were significantly decreased in a dose-dependent manner when the cells were treated with different doses of ADM (0.001-10.000 mg/L ). The IC CONCLUSIONS Idelalisib exerts effect on inhibition of the proliferation in myeloid leukemia K562 and K562/ADM cells, which may partially reverse the drug resistance of K562/ADM cells to ADM. The mechanisms for the effect of idelalisib may be related to increasing the accumulation of ADM and inducing the cell apoptosis in the K562 and K562/ADM cells.

Objective The objective of this study was to investigate the abnormal expression of Notch signaling pathway members in pancreatic cancer and its important effect on the development of pancreatic carcinoma. Methods Affymetrix gene expres-sion microarray was used to screen the differentially expressed members of Notch signal pathway in 10 cases of pancreatic carcinoma and its adjacent tissues,and verified by real-time quantitative PCR and Western blotting. The lentivirus expression vector carrying the siRNA fragment of Jagged 2(JAG2)gene was transfected into the pancreatic cancer primary cells to construct the JAG2 gene re-pression-expressing pancreatic cancer cell line. MTT,flow cytometry and Transwell assays were used to analyze cell proliferation, changes of cell cycle and invasive transfer capabilities. Results A total of 512 differentially expressed genes were detected by Affy-metrix gene expression microarray,including 419 up-regulated genes and 93 down-regulated genes. JAG2( up-regulated expres-sion 8. 20 times),NOTCH1(up-regulated expression 3. 74 times),HES1(up-regulated expression 3. 27 times),and NOTCH2(up-regulated expression 3. 16 times)were differentially expressed in Notch signaling pathway. The results of PCR and Western blotting were consistent with those of gene chip. The growth curves of JAG2 gene repressed pancreatic cancer cells and pancreatic cancer pri-mary cells were drawn by the standard OD490 value of d1-d5 by MTT assay. JAG2 gene repressor expression vector could signifi-cantly inhibit the proliferation of pancreatic cancer cells. The cell cycle analysis showed that the apoptosis and the arrested cell cycle at the S phase were significantly increased in pancreatic cancer cells with JAG2 gene repressor expression. The invasive ability was significantly reduced in JAG2 gene repressor expression pancreatic cancer cells(P<0. 05). Conclusion Some members of the Notch signaling pathway are significantly differentially expressed in pancreatic cancer tissues,and repression of this member can affect the growth,cell cycle,invasion and metastasis of pancreatic cancer cells.

The effect of melatonin on juveniles with cardio fibrosis is poorly understood. We investigated whether HDACs participate in the anti-fibrotic processes regulated by melatonin during hypertrophic remodeling. Abdominal aortic constriction (AAC) was employed in juvenile rats resulting in pressure overload-induced ventricular hypertrophy and melatonin was subsequently decreased via continuous light exposure for 5 weeks after surgery. AAC rats displayed an increased cross-sectional area of myocardial fibers and significantly elevated collagen deposition compared to sham-operated rats, as measured by HE and Masson Trichrome staining. Continuous light exposure following surgery exacerbated the increase in the cross-sectional area of myocardial fibers. The expression of HDAC1, HDAC2, HDAC3, HDAC4 and HDAC6 genes were all significantly enhanced in AAC rats with light exposure relative to the other rats. Moreover, the protein level of TNF-α was also upregulated in the AAC light exposure groups when compared with the sham. However, Smad4 protein expression was unchanged in the juveniles' hearts. In contrast, beginning 5 weeks after the operation, the AAC rats were treated with melatonin (10 mg/kg, intraperitoneal injection every evening) or vehicle 4 weeks, and sham rats were given vehicle. The changes in the histological measures of cardio fibrosis and the gene expressions of HDAC1, HDAC2, HDAC3, HDAC4 and HDAC6 were attenuated by melatonin administration. The results reveal that melatonin plays a role in the development of cardio fibrosis and the expression of HDAC1, HDAC2, HDAC3, HDAC4 and HDAC6 in cardiomyocytes.
