Esophageal cancer （EC） is a highly prevalent malignant tumor in China. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， as one of the key oncogenic pathways， can promote the cell cycle progression， proliferation， migration， and invasion， induce chemoresistance， and inhibit apoptosis and autophagy of EC cells. Traditional Chinese medicine （TCM）， with the advantages of targeting multiple points with multiple components to delay cancer progression， can target the PI3K/Akt signaling pathway for EC treatment. This article preliminarily discusses the molecular mechanism and role of the PI3K/Akt signaling pathway in EC and elaborates on the specific targets and efficacy of TCM in treating EC through intervention in the PI3K/Akt signaling pathway in the past five years. TCM materials and extracts inhibiting the PI3K/Akt signaling pathway in EC include Borneolum， spore powder of Ganoderma lucidum without spore coat， extract of Celastrus orbiculatus， root extract of Taraxacum， and Bruceae Fructus oil emulsion. TCM active ingredients exerting the effect include flavonoids， terpenoids， saponins， phenols， polysaccharides， alkaloids， and other compounds. TCM compound prescriptions with such effect include Qige San， Huqi San， Xuanfu Daizhetang， Tongyoutang and its decomposed prescriptions， Liujunzi Tang， and Xishenzhi Formula. In addition， TCM injections such as Compound Kushen Injection and Kang'ai injection also inhibit the PI3K/Akt signaling pathway in EC. This paper summarizes the role of the PI3K/Akt signaling pathway in EC and the TCM interventions， aiming to provide reference for the research and clinical application of new drugs for EC.

Objective To explore factors associated with early postoperative hormonal remission in patients with prolactinoma and to develop prediction models based on clinical and radiological features. Methods Data from 107 patients with prolactinoma who underwent transsphenoidal surgery at The First People’s Hospital of Huai’an, Nanjing Medical University between January 2020 and December 2024 was collected, included general clinical characteristics, preoperative laboratory indicators, and imaging features. Based on whether early postoperative prolactin (PRL) levels normalized, patients were divided into a remission group (n=76) and a non-remission group (n=31). Univariate logistic regression was used for preliminary evaluation of candidate variables, followed by LASSO regression for feature selection. Multiple machine learning models were constructed, including logistic regression, random forest, support vector machine, K-nearest neighbors, naive Bayes, decision tree, neural network, and gradient boosting decision tree (GBDT). All models were trained and evaluated using ten-fold cross-validation, with comprehensive assessment of model performance based on the area under the ROC curve (AUC), accuracy, sensitivity, specificity, precision, and F1 score. Results The maximum diameter of tumors in the non remission group was larger than that in the remission group (P=0.019), and the incidence of tumor stroke and preoperative PRL levels were significantly higher than those in the remission group (P＜0.001). Univariate analysis showed that sex, maximum tumor diameter, tumor stroke, and preoperative PRL levels were influencing factors for early postoperative hormone response in patients with prolactinoma (P＜0.05). The comparison results of machine learning models show that the neural network model performs the best (AUC=0.921) and has good clinical application value, followed by the GBDT model (AUC=0.893) and the support vector machine model (AUC=0.884). Other models also show certain predictive ability. Conclusions Sex, preoperative PRL levels, maximum tumor diameter, Hounsfield unit value, and tumor stroke are important factors affecting early hormone response after prolactinoma surgery. The machine learning model constructed based on the above variables has good predictive performance, and performs the best and has good clinical application value.

OBJECTIVE: To investigate the clinical efficacy of lengthened proximal femoral nail antirotation (PFNA) and InterTan in the treatment of subtrochanteric femur fractures in the elderly. METHODS: A retrospective analysis was performed on the data of 65 elderly patients diagnosed with subtrochanteric femoral fractures who met the inclusion criteria between October 2016 and January 2022. The enrolled patients were categorized into two groups according to the type of internal fixation used: the lengthened proximal femoral nail antirotation(PFNA) group and the InterTan group. There were 32 patients in the PFNA group, comprising 20 males and 12 females, with ages ranging from 60 to 85 years old with an average of (69.3±6.7 ) years old. Among these patients, 15 patients resulted from traffic accidents and 17 patients were caused by falls. According to the Seinsheimer classification system, there were 11 patients as type Ⅱ, 14 patients as type Ⅲ, 6 patients as type Ⅳ, and 1 patient as type Ⅴ. The InterTan group comprised 33 patients, including 20 males and 13 females, aged from 60 to 85 years old with an average of (69.8±7.8 ) years old. Of these, 15 patients resulted from traffic accidents, while 18 patients were caused by falls. According to the Seinsheimer classification system, 10 patients as type Ⅱ, 15 patients as type Ⅲ, 7 patients as type Ⅳ, and 1 patient as type Ⅴ. The intraoperative blood loss, operative duration, and fracture healing time were recorded and compared between two groups. The quality of fracture reduction was assessed using Chang's criteria. Additionally, the Harris hip score was utilized to evaluate hip function in both groups at 3 months postoperatively and at the final follow-up. RESULTS: All patients were followed up for a period ranging from 10 to 20 months with an average of (14.6±4.5) months. No statistically significant differences were observed between two groups in terms of operation time, intraoperative blood loss, quality of fracture reduction, or reduction methods (P>0.05). Three months after the surgery, the Harris hip score in the InterTan group was 80.0(78.0, 83.5) points, which was significantly higher than that in the PFNA group, which recorded a score of 77.5(75.0, 81.8) points. This difference was statistically significant (P<0.05). At the final follow-up, the Harris hip score in the InterTan group was 80.0(76.5, 87.0), while that in the PFNA group was 78.0(74.3, 82.8). No statistically significant difference was observed between two groups (P>0.05). CONCLUSION The use of lengthened PFNA and InterTan in the treatment of elderly subtrochanteric femur fractures can both achieve good treatment results, with the advantages of simple operation, firm fixation, and low failure rate of internal fixation. The lengthened InterTan can achieve better hip function than PFNA.

OBJECTIVE: To analyze the laboratory detection results of hemolytic disease of the fetus and newborn(HDFN). METHODS: Related test results of 283 newborns and their mothers' blood samples from Kunming Maternal and Child Health Hospital from August 2023 to May 2024 were collected, including mother and child ABO blood group, RhD blood group, as well as 3 tests of HDFN, total bilirubin (TBil) and indirect bilirubin (IBil). RESULTS: 283 were ABO incompatibility, among which 187 were HDFN positive, with a positive rate of 66.08%; the positive rate of HDFN in neonates with antigen-A incompatibility was 74.12%(126/170), the positive rate of HDFN in neonates with antigen-B incompatibility was 53.57%(60/112), which was the highest in neonates with O/A incompatibility ［75.45%(126/167)］, followed by O/B incompatibility［54.55%(60/110)］. Group by age, the positive rates of HDFN in the ≤1 d group, 2 d group, 3 d group, 4 d group, 5 d group and ≥6 d group were 76.03%(111/146), 67.86%(38/56), 57.14%(24/42), 38.46%(5/13), 46.15%(6/13) and 23.08%(3/13), respectively. With the increase of age, the positive rates of HDFN gradually decreased, there was a statistically significant difference between the ≤3 day age group and >3 day age group ( P <0.05). There was no statistically significant difference in TBil and IBil levels between the "direct antibody+indirect antibody+release+" group and the HDFN negative group in newborns. HDFN infants exhibited a rapid increase in bilirubin levels within the first day after birth, with significantly higher TBil and IBil values compared to Non ABO-HDFN infants in the ≤1 day group ( P <0.01). However, the difference of bilirubin levels between the two groups gradually narrowed from 2-6 days after birth, and the difference was not statistically significant (P >0.05). The peak value of TBil and IBil occurred on the 4th day after birth in HDFN infants. CONCLUSION ABO-HDFN is most commonly seen in newborns whose mothers are type-O, and the positive rate was the highest in newborns with O/A incompatibility. The detection rate of HDFN is affected by the age of the newborns, and the two were correlated inversely. ABO-HDFN group developed more rapidly with a higher peak. Therefore, HDFN tests should be carried out as soon as possible for mothers and newborns with incompatible blood types, and appropriate treatment should be provided to prevent complications.

The translocator protein (TSPO) positron emission tomography (PET) can noninvasively detect neuroinflammation associated with epileptogenesis and epilepsy. This study explored the role of the TSPO-targeting radioligand [¹⁸F]F-TFQC, an m-trifluoromethyl ER176 analog, in the PET neuroimaging of epileptic rats. Initially, [¹⁸F]F-TFQC was synthesized with a radiochemical yield of 8%-10% (EOS), a radiochemical purity of over 99%, and a specific activity of 38.21 ± 1.73 MBq/nmol (EOS). After determining that [¹⁸F]F-TFQC exhibited good biochemical properties, [¹⁸F]F-TFQC PET neuroimaging was performed in epileptic rats at multiple time points in various stages of disease progression. PET imaging showed specific [¹⁸F]F-TFQC uptake in the right hippocampus (KA-injected site, i.e., epileptogenic zone), which was most pronounced at 1 week (T/NT 1.63 ± 0.21) and 1 month (T/NT 1.66 ± 0.20). The PET results were further validated using autoradiography and pathological analysis. Thus, [¹⁸F]F-TFQC can reflect the TSPO levels and localize the epileptogenic zone, thereby offering the potential for monitoring neuroinflammation and guiding anti-inflammatory treatment in patients with epilepsy.

Cyclin-dependent kinase 9 (CDK9) is a member of the transcription CDK subfamily and plays a role in transcriptional regulation. Selective CDK9 degraders possess potent clinical advantages over reversible CDK9 inhibitors. Herein, we report the first ATG101-recruiting selective CDK9 degrader, AZ-9, based on the hydrophobic tag kinesin degradation technology. AZ-9 showed significant degradation effects and selectivity toward other homologous cell cycle CDKs in vitro and in vivo, which could also affect downstream related phenotypes. Mechanism research revealed that AZ-9 recruits ATG101 to initiate the autophagy-lysosome pathway, and forms autophagosomes through the recruitment of LC3, which then fuses with lysosomes to degrade CDK9 and the partner protein Cyclin T1. These dates validated the existence of non-proteasomal degradation pathway of hydrophobic driven protein degradation strategy for the first time, which might provide research ideas for chemical induction intervention on other types of pathogenic proteins.

Conclusion:AMOTL1, YAP, and TAZ may jointly participate in the malignant transformation process of cervical cancer. AMOTL1 and YAP are closely related to prognosis and may become potential prognostic indicators for cervical cancer.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

A 64-year-old male patient with hemophilia A was scheduled for the surgical removal of a pulmonary mass. Preoperative evaluation revealed that the coagulation factor Ⅷ (FⅧ) activity was 0.5%, with an F Ⅷ inhibitor level of 32 BU/ml; the R value could not be detected on the thromboelastogram. Thoracoscopic lobectomy was successfully completed. On the day of the operation and the first day after the operation, 6 mg of recombinant activated coagulation factor Ⅶ (rFⅦa) was intravenously administered every 6 h. On postoperative day 1, the patient’s blood pressure dropped and the HGB gradually declined from 102 g/L to 65 g/L. Chest X-ray revealed a large amount of pleural effusion on the left side, and urgent thoracoscopic thoracic exploration was performed. A total of 3200 mL fresh blood was cleared, and a thoracic drainage tube was placed. On postoperative day 2, the rFⅦa dose was increased to 6 mg, which was intravenously administered every 4 h, and concentrated red cells were intermittently infused to correct anemia. Four days later, due to the inability to obtain rFⅦa, PCC (50 IU/kg every 8 hours) was administered. Additionally, treatment with methylprednisolone (40 mg/d) and cyclophosphamide (200 mg, every 2 weeks) was initiated to remove FⅧ inhibitors. The thoracic drainage tube was removed on postoperative day 9, and the patient was successfully discharged 3 weeks later.
