Immune suppression in the tumor microenvironment (TME) is closely related to abnormal glycolysis. Tumor cells gain metabolic advantages and suppress immune responses through the "Warburg effect". Traditional Chinese medicine (TCM) has been shown to regulate key glycolysis enzymes (such as HK2 and PKM2), metabolic signaling pathways (such as PI3K/AKT/mTOR, HIF-1α) and non-coding RNAs at multiple targets, thus synergistically inhibiting lactate accumulation, improving vascular abnormalities, and relieving metabolic inhibition of immune cells. Studies have shown that TCM monomers and formulas can promote immune cell infiltration and functions, improve metabolic microenvironment, and with the assistance by the nano-delivery system, enhance the precision of treatment. However, the dynamic mechanism of the interaction between TCM-regulated glycolysis and TME has not been fully elucidated, for which single-cell sequencing and other technologies provide important technical support to facilitate in-depth analysis and clinical translational research. Future studies should be focused on the synergistic strategy of "metabolic reprogramming-immune activation" to provide new insights into the mechanisms of tumor immunotherapy.

Objective:To investigate the clinical characteristics and offer diagnostic and therapeutic approaches for adult-onset idiopathic hypogonadotropic hypogonadism(AIHH).Methods:Clinical, laboratory, and imaging data, as well as follow-up information, of three male patients diagnosed with AIHH at the Department of Endocrinology and Metabolism of Nanfang Hospital, Southern Medical University, were systematically reviewed and analyzed.Results:All three patients were male, with a median age of 39 years(range, 22 to 40). Two patients reported symptoms of enlarged breasts and reduced sexual function, while one case solely reported a decline in sexual function. Physical examination showed that the median length of the penis was 6 cm(range, 5 to 6 cm), and the bilateral testicular volume was 7.96 mL(4.70-8.82 mL). Basal hormone levels at the time of initial visit to our hospital as follows: the median testosterone level was 0.32 ng/mL(0.24-2.96 ng/mL), median follicle stimulating hormone(FSH) level was 0.56 mIU/mL(0.1-0.75 mIU/mL), and the median luteinizing hormone(LH) level was 0.69 mIU/mL(0.1-1.03 mIU/mL). The levels of other hormones secreted by the anterior pituitary gland were normal. Hypothalamic-pituitary magnetic resonance imaging(MRI) showed that 1 patient had a pituitary microadenoma. Three patients were treated with pulsatile GnRH or gonadotropins, one of which had hypothalamic-pituitary-gonadal(HPG) axis function reversal after GnRH pulse pump therapy and lasted for 1 year, but then still had irreversible reduction.Conclusion:AIHH is marked by adult-onset disease and idiopathic hypogonadism. Enhancing fertility remains a critical requirement for these patients. Pulsatile GnRH treatment or gonadotropin therapy, as viable treatments, exhibit therapeutic effects, albeit with occasional fluctuations. Therefore, the emphasis lies in the timely consideration of fertility preservation.

Objective To establish a human α-synuclein nuclear localization signal transgenic mouse model and investigate the effects of α-synuclein nuclear localization on the behavior of mice.Methods Human α-synuclein nuclear localization signal and EGFP lentiviral vectors were constructed.Transgenic mice were created with the microinjection method.Using PCR and Western Blot method to identify the genotypes and protein expression of the transgenic founder mice and their offsprings.The immunofluorescence was used to examine the localization of human α-synuclein in the mouse brain tissue.The behavioral changes of the transgenic mice were evaluated by the open field test,rotarod test,and O maze test.Results The h SNCA-NLS gene was successfully inserted into the mouse genome,the human α-syn was successfully expressed,and the human α-syn has localized with the nuclear.Further studies found that human α-synuclein nuclear localization signal transgenic mice had significant motor dysfunction,astrocyte proliferation and inflammatory response at 2 months of age and exhibited significant anxiety-like symptoms and reduced expression of the γ-aminobutyric acid(GABA)gene at 9 months of age,which persisted until 12 months of age.Conclusions A human α-synuclein nuclear localization signal transgenic mouse model has been successfully established.The mice exhibit significant motor dysfunction and anxiety-like symptoms.The successful establishment of this model provides a foundation for studying the role of α-syn nuclear localization in Parkinson's disease.

Complete androgen insensitivity syndrome(CAIS) is characterized by lack of androgen response in target organs due to androgen receptor dysfunction, resulting in feminized external genitalia. Individuals with CAIS are typically advised to live as females. This article reports a patient diagnosed with CAIS and gender dysphoria in adulthood. Following the removal of a left pelvic mass, pathology indicated cryptorchidism with a concurrent Leydig cell tumor. Genetic testing revealed a deletion mutation in exon 3 of androgen receptor gene. During follow-up, the patient underwent gender reassignment, transitioning socially from female to male. This case provides new insights into gender allocation for CAIS patients.

Sino-foreign cooperative education not only introduces foreign teachers and curriculums, but also brings new teaching concepts, teaching methods, and the training of teachers. With the example of rehabilitation treatment in the national first-class undergraduate specialty construction site of Nanjing University of Chinese Medicine, this study discusses the talent training mode of Sino-foreign cooperative education from the five aspects of professional system, discipline characteristics, curriculum system, teaching methods, and evaluation methods. The mode of Sino-foreign cooperative education provides a reference for the development of modern rehabilitation higher education.

ObjectiveTo explore the pharmacodynamic effect of the water extract of Citri Grandis exocarpium （WEC） on mice with alcohol-induced acute liver injury and provide data support for the development of this medicinal for anti-alcoholism and liver protection. MethodThe main components of WEC were determined by high performance liquid chromatography （HPLC）. Sixty Balb/c mice were randomized into 6 groups： control group （equal volume of 0.5% carboxymethyl cellulose sodium solution）， model group （equal volume of 0.5% carboxymethyl cellulose sodium solution）， low-， medium-， and high-dose WEC groups （0.5， 1.0， 2.0 g·kg^-1）， and Haiwang Jinzun tablet positive control group （2.0 g·kg^-1）. The administration lasted 14 days. One day before the end of the administration， mice were fasted for 12 h with free access to water. The mice， except the control group， were given 56° Chinese liquor （13 mL·kg^-1）. After 2 h， blood was taken from eyeballs and the liver was dissected and weighed. Automatic biochemical analyzer was employed to detect the expression of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， and alcohol dehydrogenase （ADH）. The pathological changes of liver tissues were observed based on hematoxylin-eosin （HE） staining， and apoptosis of hepatocytes based on TUNEL/DAB staining. The expression of proteins related to apoptosis was detected by Western blot. ResultAccording to the HPLC fingerprint， the main components of WEC were rhoifolin and naringin. Compared with the control group， the model group showed increase in liver/body weight ratio （P<0.01） and the expression of ALT and AST （P<0.05， P<0.01）， decrease in the expression of ADH （P<0.05）， blurred structure of hepatic lobules， pathological changes of liver tissue， loose cytoplasm with edema， severe steatosis， rise of the TUNEL-positive rate （P<0.01）， reduction in expression of Bcl-2 （P<0.01）， and increase in Bax and Caspase-3 （P<0.01）. Compared with the model group， medium-dose WEC lowered liver/body weight ratio （P<0.05）. All doses of WEC depressed the activity of ALT and AST （P<0.05， P<0.01）， up-regulated the expression of ADH （P<0.05）， significantly improved the pathological features of alcohol-induced cytoplasmic porosity， edema， and steatosis， down-regulated the TUNEL-positive rate （P<0.05， P<0.01）， enhanced the expression of Bcl-2 （P<0.05）， and decreased Bax and Caspase-3 （P<0.01）. ConclusionWEC regulates the expression of ALT， AST， and ADH and improves hepatic steatosis and hepatocyte apoptosis to fight against acute liver injury.

Objective:To review the experience of closure of the left-main-bronchial stump fistula using endoscopic liner cutter staplers through the right thoracic approach and I stage or staged treatment for the left pyothorax.Methods:6 patients with the left-main-bronchial stump fistula after left pneumonectomy combined with pyothorax were treated by closing the left-main-bronchial stump using endoscopic liner cutter staplers through the right thoracic approach, and pleura was used to cover the distal and proximal incisional margin of the stump respectively. The thoracic T-tube drainage was used in the I stage or staged treatment for the left pyothorax.Results:All patients were survived without recurrence of the bronchopleural fistula. 4 patients were observed to have no recurrence of pyothorax when 1 patient had recurrence of pyothorax and was treated with intermittent T-tube drainage.1 patient operated with left-thoracic fenestration in the past was treated with drainage waiting for secondary operation.Conclusion:The right thoracic approach seemed to be a safer and more effective method than the transsternal transpericardial approach in cases with the left-main-bronchial stump fistula combined with pyothorax. The use of endoscopic liner cutter staplers reduced the risk of bleeding, infection and recurrence of fistula. The T-tube drainage in the I stage or staged treatment for the left pyothorax was considered to be an easier way for treatment.
