Height， as one of the crucial indicators for assessing children’s growth and development， has consistently been a global focus. With economic development and improvements in social living standards， the clinical management needs for children with short stature have been increasingly growing. While growth hormone brings hope to children with short stature， it also triggers ethical challenges such as medical standardization， expansion of indications， equitable accessibility， and informed consent. To avoid the ethical issues related to the use of pediatric growth hormone， multidimensional and comprehensive clinical management should be implemented for children with short stature， including strictly adhering to medical standards and ethical guidelines， enhancing public awareness， and promoting the standardized development of recombinant human growth hormone （rhGH） therapy and ethics.

OBJECTIVE: To investigate the effectiveness of using 3 hollow compression screws combined with 1 screw off-axis fixation under the guidance of three-dimensional (3D) printed guide plate with mortise-tenon joint structure (mortise-tenon joint plate) for the treatment of Pauwels type Ⅲ femoral neck fractures. METHODS: A clinical data of 78 patients with Pauwels type Ⅲ femoral neck fractures, who were admitted between August 2022 and August 2023 and met the selection criteria, was retrospectively analyzed. The operations were assisted with mortise-tenon joint plates in 26 cases (mortise-tenon joint plate group) and traditional guide plates in 28 cases (traditional plate group), and without guide plates in 24 cases (control group). There was no significant difference in the baseline data of gender, age, body mass index, cause of injury, and fracture side between groups ( P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, incision length, incidence of postoperative deep vein thrombosis of lower extremity, pain visual analogue scale (VAS) score at 1 week after operation, and Harris score of hip joint at 3 months after operation were recorded and compared. X-ray re-examination was taken to check the quality of fracture reduction, fracture healing, and the shortening length of the femoral neck at 3 months after operation, and the incidences of internal fixation failure and osteonecrosis of the femoral head during operation. RESULTS: Compared with the control group, the operation time, intraoperative blood loss, and frequency of intraoperative fluoroscopy reduced in the two plate groups, and the quality of fracture reduction was better, but the incision was longer, and the differences were significant ( P<0.05). The operation time and intraoperative blood loss were significantly higher in the traditional plate group than in the mortise-tenon joint plate group ( P<0.05), the incision was significantly longer ( P<0.05); and the difference in fracture reduction quality and the frequency of intraoperative fluoroscopy was not significant between two plate groups ( P>0.05). There was 1 case of deep vein thrombosis of lower extremity in the traditional plate group and 1 case in the control group, while there was no thrombosis in the mortise-tenon joint plate group. There was no significant difference in the incidence between groups ( P>0.05). All patients were followed up 12-15 months (mean, 13 months). There was no significant difference in VAS score at 1 week and Harris score at 3 months between groups ( P>0.05). Compared with the control group, the fracture healing time and the length of femoral neck shortening at 3 months after operation were significantly shorter in the two plate groups ( P<0.05). There was no significant difference between the two plate groups ( P>0.05). There was no significant difference in the incidences of non-union fractures, osteonecrosis of the femoral head, or internal fixation failure between groups ( P>0.05). CONCLUSION For Pauwels type Ⅲ femoral neck fractures, the use of 3D printed guide plate assisted reduction and fixation can shorten the fracture healing time, reduce the incidence of postoperative complications, and be more conducive to the early functional exercise of the affected limb. Compared with the traditional guide plate, the mortise-tenon joint plate can reduce the intraoperative bleeding and shorten the operation time.

B and T lymphocyte attenuator (BTLA) is an inhibitory immune checkpoint, which typically interacts with herpesvirus entry mediator (HVEM) and plays a crucial role in regulating immune balance. BTLA interacts with its ligand HVEM in a cis manner on the surface of the same immune cell to maintain immune tolerance, while trans interactions on the surface of different immune cells mediate immunosuppressive effects. Dysregulation of the BTLA/HVEM axis can impair the functions of immune cells, particularly T lymphocytes, promoting immune escape of tumor cells and ultimately leading to tumor progression. Researchers have found that BTLA and HVEM are abnormally expressed in various tumors and are associated with prognosis, suggesting that they may be potential targets for tumor immunotherapy. This review summarizes the molecular structures of BTLA and HVEM, immunomodulatory mechanisms, recent advances in hematologic malignancies, potential inhibitors of BTLA/HVEM interaction, and their applications in immunotherapy for hematologic malignancies.

Alzheimer's disease (AD) is the leading cause of dementia, and no effective treatment has been developed for it thus far. Recently, the use of natural compounds in the treatment of neurodegenerative diseases has garnered significant attention owing to their minimal adverse reactions. Accordingly, the potential therapeutic effect of pterostilbene (PTS) on AD has been demonstrated in multiple in vivo and in vitro experiments. In this study, we systematically reviewed and summarized the results of these studies investigating the use of PTS for treating AD. Analysis of the literature revealed that PTS may play a role in AD treatment through various mechanisms, including anti-oxidative damage, anti-neuroinflammation, anti-apoptosis, cholinesterase activity inhibition, attenuation of β-amyloid deposition, and tau protein hyperphosphorylation. Moreover, PTS interferes with the progression of AD by regulating the activities of peroxisome proliferator-activated receptor alpha (PPAR-α), monoamine oxidase B (MAO-B), silent information regulator sirtuin 1 (SIRT1), and phosphodiesterase 4A (PDE4A). Furthermore, to further elucidate the potential therapeutic mechanisms of PTS in AD, we employed network pharmacology and molecular docking technology to perform molecular docking of related proteins, and the obtained binding energies ranged from -2.83 to -5.14 kJ/mol, indicating that these proteins exhibit good binding ability with PTS. Network pharmacology analysis revealed multiple potential mechanisms of action for PTS in AD. In summary, by systematically collating and summarizing the relevant studies on the role of PTS in treatment of AD, it is anticipated that this will serve as a reference for the precise targeted prevention and treatment of AD, either using PTS or other developed drug interventions.

LC-MS/MS methods for the quantitative determination of mecobalamin and ceftriaxone in rat plasma were established, and utilized to assess the pharmacokinetic behaviors of the two drugs in rats and to determine whether there were pharmacokinetics-based drug-drug interactions between them. Methanol was used as a protein precipitant to process rat plasma samples. For mecobalamin, acetonitrile containing 0.1% formic acid was used as the organic phase, while an aqueous solution of 0.1% formic acid and 2 mmol/L ammonium acetate served as the aqueous phase. For ceftriaxone, the organic phase was acetonitrile with 0.1% formic acid, and the aqueous phase was a 1% formic acid aqueous solution. LC-MS/MS quantitative analysis methods for both drugs were developed under the positive ion mode, followed by comprehensive methodological validation. Single-dose administration (either alone or in combination) was carried out via caudal vein injection. The dosing regimens were 0.03, 0.1, and 0.3 mg/kg for mecobalamin and 90 mg/kg for ceftriaxone. The results of methodological validation indicated that mecobalamin exhibited good linearity in the range of 3−3000 ng/mL (r = 0.9991), and ceftriaxone showed excellent linearity in the range of 0.5~500 μg/mL (r = 1). The selectivity, precision, accuracy, extraction recovery, matrix effect, and stability of the analytical methods for both substances met the relevant requirements. The pharmacokinetic study revealed that, compared with single-drug administration, the average plasma concentration-time profiles of the two drugs almost overlapped during single-dose combined administration. Statistical analysis, specifically one-way analysis of variance, demonstrated no significant differences in major pharmacokinetic parameters (t1/2, AUC0−∞, etc.) (P > 0.05). This study confirmed that no pharmacokinetic-based drug-drug interactions occurred when mecobalamin and ceftriaxone were co-administered in rats. The findings of this research offer a reliable pharmacokinetic foundation for the rational clinical co-use of these two drugs, thus providing valuable insights into optimizing therapeutic strategies.

Background and objective Different degrees of self-transcendence exist in lung cancer patients,which can stimulate patients'self-awareness and promote them to face negative events in life positively,thus improving pa-tients'quality of life and treatment outcomes.However,there are few reports on self-transcendence in lung cancer patients in China,and the related influencing factors have not yet been clarified.This study aims to investigate the current situation of self-transcendence in lung cancer patients and explore its risk factors,so as to provide a theoretical basis for clinical intervention decision-making.Methods 243 lung cancer patients who were admitted to the Department of Lung Cancer Center of West China Hospital,Sichuan University from September 2023 to February 2024 were enrolled as the study subjects;general infor-mation questionnaire,self-transcendence scale,Herth hope scale and social support scale were used for the investigation.The influencing factors related to self-transcendence of lung cancer patients were analyzed.Results The total mean score of self-transcendence in lung cancer patients was(44.73±8.94);the total mean score of hope level was(37.60±4.98),and the total mean score of social support was(41.31±7.27).Self-transcendence was positively correlated with hope level and social support(P＜0.001,P＜0.001).Education,hope level and social support were influencing factors of self-transcendence in lung cancer pa-tients(P＜0.05,P＜0.001,P＜0.05).Conclusion Self-transcendence in lung cancer patients was at a low level and was influenced by hope level and social support.Healthcare professionals should pay attention to improving the hope level of lung cancer pa-tients,carrying out targeted psychological interventions,and at the same time guiding them to enhance the perception of social support,so as to promote the realization of self-transcendence in patients.

Objective To understand the genotyping of human immunodeficiency virus (HIV) co-infected hepatitis C virus (HCV) patients in Yunnan Province, and to analyze the differences in viral load, biochemical indicators, and blood routine indicators among different genotypes, in order to provide a laboratory basis for the diagnosis and clinical treatment of HIV/HCV co-infected patients. Methods From November 2022 to June 2023, the serum samples and basic information of patients diagnosed with HIV/HCV co-infection were collected in the antiviral outpatient clinic of Yunnan Provincial Hospital of Infectious Diseases. The HCV viral load was detected by one-step qRT-PCR amplification, the positive samples were sequenced, and genotyping was determined based on NS5 gene sequence. The differences in biochemical and blood routine indexes between HIV patients co-infected with different HCV genotypes and low/high viral loads were analyzed. Results A total of 126 HIV/HCV co-infected patients were collected, including 20 HCV genotype 1 (15.9%), 91 HCV genotype 3 (72.2%), and 15 HCV genotype 6 (11.9%). The maximum and minimum viral load of the three HCV genotypes were as follows: HCV type 1 (1.0×108, 4.8×104 IU/mL), HCV type 3 (2.2×108, 2.9×102 IU/mL), and HCV type 6 (8.1×107, 6.8×104 IU/mL). The results showed that there was no significant difference between HIV co-infection with different genotypes of HCV and three HIV treatment schemes, including nucleoside reverse transcriptase inhibitors+integrase strand transfer inhibitors (NRTIs+INSTIs), nucleoside reverse transcriptase inhibitors+non-nucleoside reverse transcriptase inhibitors (NRTIs+NNRTIs) and nucleoside reverse transcriptase inhibitors+protease inhibitor (NRTIs+PLs), and the viral load of patients (P>0.05). The analysis of biochemical indexes such as total bilirubin (TBIL), direct bilirubin (DBIL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CREA), and blood routine indexes such as white blood cell (WBC), red blood cell (RBC), hemoglobin (HGB), platelet (PLT), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) among different HCV genotypes and low/high viral loads showed that there was no significant difference in biochemical indexes and blood routine indexes between low/high viral loads of HIV co-infected HCV patients (P>0.05); however, the biochemical indicators TBIL, IBIL and MCHC were significantly different statistically between patients with genotype 3 HCV infection and those with genotype 1 HCV infection (P<0.05), while other biochemical and blood routine indexes were not statistically different among different HCV genotypes (P>0.05). Conclusions There are six subtypes of HCV co-infection in HIV patients in Kunming, Yunnan Province, including three genes of genotype 1, 3, and 6. Among them, genotype 3 HCV is the main prevalent genetic virus among HIV co-infected populations. The TBIL, IBIL and MCHC values of HIV patients co-infected with HCV type 3 are different from those infected with HCV type 1.

Objective:To explore the construction and application of an evidence-based practice plan for early postoperative activity in postoperative patients with large area cerebral infarction.Methods:Ninety-six postoperative patients with large area cerebral infarction admitted to Wenzhou Central Hospital from July 2021 to April 2023 were selected as the study subjects for a Clinical trial. They were divided into the control group (48 cases) and the observation group (48 cases) by random number table method. The control group received routine postoperative care for neurosurgery, while the observation group received evidence-based systematic early activity training. Both groups were followed up until 1 month after the patient was discharged from the hospital. The time of postoperative hospitalization, hospitalization expenses, vital signs and pain investigation 48 h after surgery, daily living ability before intervention and 7 d, 1 month after discharge, neurological function before intervention and 7 d and 1 month after surgery, and complications during follow-up between the two groups were compared.Results:In the control group, there were 29 males and 19 females, with an average age of 43-67(56.87 ± 1.76) years. In the observation group, there were 31 males and 17 females, with an average age of 43-68 (57.02 ± 1.82) years. The postoperative hospital stay in the observation group was (6.87 ± 0.65) d, in the control group was (9.06 ± 0.72) d, the difference between them was significant ( t=15.64, P<0.05). 48 hours after surgery, the heart rate, breathing rate and mean arterial pressure in the observation group were (71.65 ± 0, 45) times/min, (14.76 ± 0.36) times/min and (76.98 ± 5.65) mmHg(1 mmHg=0.133 kPa), which were different with those in the control group, (82.76 ± 2.65) times/min, (18.76 ± 2.87) times/min and (93.76 ± 5.93) mmHg ( t=28.64, 9.58 and 14.19, all P<0.05). Seven days after discharge, the score of Activities of Daily Living and the National Institutes of Health Neurological Impairment Scale in the observation group were (84.65 ± 2.45) and (23.65 ± 2.65), which were different than the (79.76 ± 1.97) and (28.54 ± 2.73) in the control group ( t=10.26, 8.91, both P<0.05). A month after discharge, the score of Activities of Daily Living and the National Institutes of Health Neurological Impairment Scale in the observation group were (95.45 ± 1.43) and (18.65 ± 1.98), while in the control group were (87.87 ± 1.39) and (21.54 ± 2.76), the difference between them were significant ( t=26.33, 5.90, both P<0.05). The total incidence of complications such as postoperative bleeding, postoperative infection and hypoxemia in the observation group was 20.83% (10/48), which was significant lower than the 68.75% (33/48) in the control group ( χ2=22.28, P<0.05). Conclusions:Evidence-based systematic early activity training could significantly alleviate postoperative pain in patients with large area cerebral infarction after surgery, improve their daily living ability and neurological function, further effectively shorten their hospitalization time, and reduce the occurrence of complications.

Objective:To evaluate the effects of different types of psychological interventions on the fear of cancer recurrence through a network Meta-analysis.Methods:Randomized controlled trials on the effects of different types of psychological interventions on the fear of cancer recurrence were retrieved from PubMed, PsycINFO, Web of Science, The Cochrane Library, Embase, EBSCO, China Biomedical Literature Database, CNKI, Wanfang Database and Vip Database. The retrieval period was from the establishment of the database to December, 31 2022. Two researchers conducted literature screening, extraction and quality evaluation, and used Stata14.0 software to conduct network Meta-analysis.Results:A total of 29 pieces of research involving 3 068 cancer patients and 11 psychological intervention measures. The results of network Meta-analysis showed that narrative therapy, PERMA(Positive, Engagement, Relationship, Meaning, Accomplishment) happiness theory model, acceptance and commitment therapy and cognitive behavior therapy had statistically significant differences in the intervention effect on the fear of cancer recurrence compared with conventional nursing ( SMD values were -1.93--0.83, all P<0.05); there was no significant difference among narrative therapy, PERMA happiness model, acceptance and commitment therapy and gratitude-expansion behavior theory (all P>0.05). The results of the cumulative probability map showed the best intervention was narrative therapy. Conclusions:The results of this study suggest that narrative therapy, acceptance and commitment therapy, and cognitive behavior therapy may be effective psychological intervention measures to improve the fear of cancer recurrence. However, more studies are still needed for further verification.
