Objective:To explore whether transjugular intrahepatic portosystemic shunt (TIPS) can improve the prognosis of esophagogastric variceal bleeding (EGVB) combined with sarcopenia in cirrhotic patients.Methods:A retrospective cohort study was performed. A total of 464 cases with cirrhotic EGVB who received standard or TIPS treatment between January 2017 and December 2019 were selected. Regular follow-up was performed for the long-term after treatment. The primary outcome was transplantation-free survival. The secondary endpoints were rebleeding and overt hepatic encephalopathy (OHE). The obtained data were statistically analyzed. The t-test and Wilcoxon rank-sum test were used to compare continuous variables between groups. The χ2 test, or Fisher's exact probability test, was used to compare categorical variables between groups. Results:The age of the included patients was 55.27±13.86 years, and 286 cases were male. There were 203 cases of combined sarcopenia and 261 cases of non-combined sarcopenia. The median follow-up period was 43 months. The two groups had no statistically significant difference in follow-up time. There was no statistically significant difference in transplant-free survival between the TIPS group and the standard treatment group in the overall cohort ( HR=1.31, 95% CI: 0.97-1.78, P=0.08). The TIPS patient group with cirrhosis combined with sarcopenia had longer transplant-free survival (median survival: 47.76 vs. 52.45, χ2=4.09; HR=1.55, 95 CI: 1.01~2.38, P=0.04). There was no statistically significant difference in transplant-free survival between the two kinds of treatments for patients without sarcopenia ( HR=1.22, 95% CI: 0.78~1.88, P=0.39). Rebleeding time was prolonged in TIPS patients with or without sarcopenia combination (patients without combined sarcopenia: median rebleeding time: 39.48 vs. 53.61, χ2=18.68; R=2.47, 95 CI: 1.67~3.65, P<0.01; patients with sarcopenia: median rebleeding time: 39.91 vs. 50.68, χ2=12.36; HR=2.20, 95 CI: 1.42~3.40, P<0.01). TIPS patients had an increased 1-year OHE incidence rate compared to the standard treatment group (sarcopenia patients: 6.93% vs. 16.67%, χ2=3.87, P=0.049; patients without sarcopenia combination: 2.19% vs. 9.68%, χ2=8.85, P=0.01). There was no statistically significant difference in the long-term OHE incidence rate between the two kinds of treatment groups ( P>0.05). Conclusion:TIPS can significantly prolong transplant-free survival compared to standard treatment as a secondary prevention of EGVB concomitant with sarcopenia in patients with cirrhosis. However, its advantage is not prominent for patients with cirrhosis in EGVB without sarcopenia.

Objective:To investigate the effect of estrogen-related receptor α (ESRRA)-mediated lipophagy on the proliferation and migration abilities of nasopharyngeal carcinoma cells.Methods:A total of 16 clinical samples diagnosed by pathology in the Affiliated Hospital of Nantong University from 2021 to 2023 were selected, including 8 normal nasopharyngeal mucosa tissues and 8 nasopharyngeal carcinoma tissues. Immortalized normal nasopharyngeal epithelial cell line NP69 and nasopharyngeal carcinoma cell lines C666-1, CNE2, TW03-EBV and TW03 were selected. The cell lines C666-1 and CNE2 were divided into the siR-NC group (transfected with small interfering RNA negative control sequence) and siR-ESRRA group (transfected with small interfering RNA against ESRRA gene). The relative expression levels of ESRRA were detected by Western blotting and immunohistochemical assay. EdU assay was used to detect the proliferation ability of C666-1 and CNE2 cells, and Transwell assay was used to detect the migration ability. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the relative expression levels of ESRRA and perilipin 3 (PLIN3) mRNA. The formation of lipophagy in C666-1 and CNE2 cells was observed by transmission electron microscopy. The co-localization of LC3, PLIN3 and LAMP2 with lipid droplets labeling with Bodipy was detected by immunofluorescence assay. Dual-luciferase reporter gene assay was used to verify the targeting relationship between ESRRA and PLIN3.Results:The relative expression level of ESRRA in nasopharyngeal carcinoma tissues was higher than that in normal nasopharyngeal mucosa tissues(1.15±0.75 vs. 0.32±0.21, t = 3.02, P = 0.009). The relative expression level of ESRRA in nasopharyngeal carcinoma cell lines C666-1 (1.539±0.044), CNE2 (1.420±0.030), TW03-EBV (2.867±0.044), and TW03 (1.323±0.022) were higher than that in normal nasopharyngeal epithelial cell line NP69 (0.094±0.002), and the difference was statistically significant ( F = 34.08, P < 0.001).The results of EdU assay showed that the proportions of EdU labeled positive cells in CNE2 cells of siR-NC group and siR-ESRRA group were (70.44±4.06)% and (51.51±0.92)% ( t = 7.88, P = 0.001), and the proportions in C666-1 cells were (62.25±3.89)% and (54.91±0.27)% ( t = 3.26, P = 0.031). The results of Transwell assay showed that the number of migrating cells in CNE2 and C666-1 cells was less than that in siR-NC group [CNE2 cells: (181±7) cells vs. (261±21) cells; C666-1 cells: (201±16) cells vs. (256±7) cells], and the differences were statistically significant ( t = 6.30, P = 0.003; t = 5.43, P = 0.006). According to qRT-PCR results, the relative expression level of PLIN3 mRNA in the siR-ESRRA group was higher than that in the siR-NC group (CNE2 cells: 1.58±0.16 vs. 0.83±0.17, t = 5.59, P = 0.005; C666-1 cells: 1.37±0.12 vs. 1.06±0.06, t = 3.86, P = 0.018). The dual-luciferase reporter gene assay results indicated a targeted binding interaction between PLIN3 and ESRRA. Transmission electron microscopy observation showed that the lipid droplets in nasopharyngeal carcinoma cells increased and the binding to autophagosomes decreased after knockdown of ESRRA. The results of immunofluorescence assay demonstrated that, in contrast to the siR-NC group, there was a decrease in the co-localization of LC3 and LAMP2 and an increase in the co-localization of lipid droplets with PLIN3. Conclusions:ESRRA is highly expressed in nasopharyngeal carcinoma tissues and cells. As a transcription repressor, ESRRA may work to prevent PLIN3 from being transcribed, decrease lipid droplet stability, mediate lipophagy, and promote proliferation and migration of nasopharyngeal carcinoma cells.

After entering the body from the drug delivery site, antitumor nanomedicines need to cross a series of physiopathological barriers to reach the target site of action to effectively exert antitumor therapeutic effects. The ligand modification strategy is a classic method to enhance the efficiency of nanomedicine delivery in vivo, but the contradiction between the single ligand modification strategy, which is characterized by unity and stage, and the in vivo delivery process, which is characterized by versatility and whole-process characteristics, determines that nanomedicines modified by a single ligand alone cannot satisfy the target efficacy requirements. Therefore, the use of multiligand combinatorial modification strategies by virtue of nanomedicine surface area advantages is key to advancing the next generation of smart nanomedicines. In this paper, on the basis of summarizing and classifying the commonly used functional ligands for in vivo delivery, the advantages and research progress of multiligand combination modification of antitumor nanomedicines are discussed with special focus, and the multiligand combination modification is classified as synergistic and complementary according to the combination of the ligands, which is of great significance to ensure that antitumor nanomedicines can overcome the multiple physiopathological barriers to achieve precise delivery.

Objective To investigate the efficacy of flupentixol combined with ondansetron in preventing postoperative nausea and vomiting(PONV)in patients receiving sufentanil and dezocine patient-controlled intravenous analgesia(PCIA).Methods Surgical patients receiving sufentanil and dezocine PCIA were randomly divided into treatment and control groups using a random number table.The control group received sufentanil 150 μg,dezocine 20 mg,and ondansetron 8 mg for PCIA,while the treatment group received sufentanil 150 μg,dezocine 20 mg,flupentixol 5 mg,and ondansetron 8 mg for PCIA.The incidence of PONV,severity of PONV,heart rate(HR),mean arterial pressure(MAP),blood oxygen saturation(SPO2)levels at different time points after surgery,surgery-related indicators,visual analogue scale(VAS)scores,Ramsay scores,PCIA pressing times,and incidence of adverse drug reactions were compared between the two groups.Results The incidence of PONV in the treatment group and the control group at 2,12,24,36 and 48 hours after surgery were 1.64％,4.84％,6.56％,3.28％,0 and 14.75％,18.03％,19.67％,16.39％,9.84％,respectively.The HR at 24 hours after surgery in the treatment group and the control group were(91.42±8.75)and(98.13±9.62)beat·min-1,respectively;the MAP were(91.98±4.56)and(99.05±4.17)mmHg;SPO2 were(98.13±1.65)％and(98.95±1.82)％;VAS scores were 2.68±0.49 and 2.97±0.63;Ramsay scores were 2.27±0.65 and 2.05±0.32;PCIA pressing times were(2.14±0.37)and(4.36±0.78)times,respectively.The differences in the above indicators between the treatment group and the control group were statistically significant(all P＜0.05).The incidence of total adverse drug reactions after surgery in the treatment group and the control group were 13.12％and 8.20％,respectively,with no statistically significant difference(P＞0.05).Conclusion Flupentixol combined with ondansetron can reduce the risk of PONV caused by sufentanil combined with dezocine PCIA after surgery,ensuring good analgesic effects and safety.

Objective To investigate disease characteristics and hospitalization costs of children with Mycoplasma Pneumoniae pneumonia(MPP)admitted to Shanghai municipal medical hospitals from 2019 to 2023.Methods Depending on the Shanghai Municipal Hospital Pediatric Alliance,we retrospectively investigated community acquired MPP pediatric patients hospitalized in 22 municipal hospitals with pediatric qualifications(including 4 children's hospitals)in Shanghai from Jan 2019 to Dec 2023.We collected the patients'diagnosis codes,gender,age,length of hospital stay,hospitalization costs,and whether they progressed to severe Mycoplasma pneumoniae pneumonia(SMPP).Results From 2019 to 2023,a total of 29 045 hospitalized children with MPP were treated,with 6 035 cases(20.8%)identified as SMPP in the 22 hospitals.Trend analysis revealed a rising trend with years in the proportion of SMPP patients(χ2trend=365.498,P<0.001).Among the 4 children's hospitals,there were 18 710 cases with MPP,including 4 078 cases(21.8%)of SMPP.The proportion of SMPP patients also showed an increasing trend with years(χ2trend=14.548,P<0.001),and the proportion in 2023(23.0%)was higher than that in previous years with statistical significance.There were statistical differences in the seasonal distribution of MPP cases between different years,with higher proportions in summer and autumn overall.The age distribution of hospitalized MPP children varied among different years,with school-age children accounting for the majority(56.8%)in 2023.There was no difference in the distribution of severe cases between different genders,but there were differences in the proportion of severe cases among different age groups in different years,with a gradual increase in severe cases among children aged 1 to 3 years(χ2trend=191.567,P<0.001).The average length of hospital stay for MPP during the epidemic was higher than that during non-epidemic periods,and there were statistically significant differences in the average length of hospital stay between different years(P<0.001).The individual hospitalization costs during the epidemic were higher than in other years,and there were statistically significant differences in individual hospitalization costs between different years(P<0.001).The total hospitalization costs were still higher in 2019 and 2023.The individual hospitalization costs for SMPP were higher than for non-SMPP cases.Conclusion MPP outbreaks occurred in Shanghai in 2019 and 2023,with the higher proportions in summer and autumn overall.Compared to previous years,the number of hospitalized MPP children in Shanghai was higher in 2023,with a higher proportion of SMPP cases,especially among children under 3 years old.The individual per capita hospitalization expenses for SMPP cases were higher than for non-SMPP cases.

Objective To investigate the relationship between serum lipid profiles and colorectal adenomas,and to benefit the prevention of colorectal cancer.Methods This study retrospectively analyzes the serum lipid profiles and clinical parameters of 2,960 patients who were diagnosed with colorectal adenomas,and 3,156 individuals without colorectal adenomas in Meizhou People's Hospital from May 2018 to May 2020.The association between serum lipid profiles and colorectal adenoma was evaluated by Logistic regression analysis.Results It was observed that the serum levels of total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C)and apoliprotein B(ApoB)were significantly elevated in patients with colorectal adenomas.Dyslipidemia was more prevalent in adenoma cases than in controls.The Logistic regression analysis suggested that serum TC and TG levels were positively associated with the occurrence of colorectal adenomas.Conclusion Elevated serum TG and TC levels are independent risk factors for adenoma,and adenoma patients with elevated serum TG and TC levels may be more likely to develop high-risk adenoma.

Objective:To investigate the effect of CD8+CD28-T cells on acute graft-versus-host disease(aGVHD)after haploidentical hematopoietic stem cell transplantation(haplo-HSCT).Methods:The relationship between absolute count of CD8+CD28-T cells and aGVHD in 60 patients with malignant hematological diseases was retrospectively analyzed after haplo-HSCT,and the differences in the incidence rate of chronic graft-versus host disease(cGVHD),infection and prognosis between different CD8+CD28-T absolute cells count groups were compared.Results:aGVHD occurred in 40 of 60 patients after haplo-HSCT,with an incidence rate of 66.67％.The median occurrence time of aGVHD was 32.5(20-100)days.At 30 days after the transplantation,the absolute count of CD8+CD28-T cells of aGVHD group was significantly lower than that of non-aGVHD group(P=0.03).Thus the absolute count of CD8+CD28-T cells at 30 days after transplantation can be used to predict the occurrence of aGVHD to some extent.At 30 days after transplantation,the incidence rate of aGVHD in the low cell count group(CD8+CD28-T cells absolute count＜0.06/μl)was significantly higher than that in the high cell count group(CD8+CD28-T cells absolute count ≥0.06/μl,P=0.011).Multivariate Cox regression analysis further confirmed that the absolute count of CD8+CD28-T cells at 30 days after transplantation was an independent risk factor for aGVHD,and the risk of aGVHD in the low cell count group was 2.222 times higher than that in the high cell count group(P=0.015).The incidence of cGVHD,fungal infection,EBV infection and CMV infection were not significantly different between the two groups with different CD8+CD28-T cells absolute count.The overall survival,non-recurrent mortality and relapse rates were not significantly different between different CD8+CD28-T cells absolute count groups.Conclusion:Patients with delayed CD8+CD28-T cells reconstitution after haplo-HSCT are more likely to develop aGVHD,and the absolute count of CD8+CD28-T cells can be used to predict the incidence of aGVHD to some extent.The absolute count of CD8+CD28-T cells after haplo-HSCT was not associated with cGVHD,fungal infection,EBV infection,and CMV infection,and was also not significantly associated with the prognosis after transplantation.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To compare the effect of holmium laser enucleation of the prostate(HoLEP)with that of transurethral resection of the prostate(TURP)on the prostate function,oxidative stress indicators and sexual function of the patient with BPH.Methods:We randomly assigned 100 BPH patients to receive HoLEP(n=50)or TURP(n=50)in our hospital from June 2021 to June 2023,and compared the perioperative parameters,prostate function,oxidative stress indicators,sexual function and postopera-tive complications between the two groups.Results:The intraoperative blood loss was significantly less and the time of catheterization,bladder irrigation and hospital stay remarkably shorter in the HoLEP than in the TURP group(P＜0.05).The postoperative IPSS and quality of life(QOL)scores were markedly lower,level of superoxide dismutase(SOD)higher,content of malondialdehyde(MDA)and total antioxidant capacity(T-AOC)lower,IIEF-5 and Erection Hardness Grading Scale(EHGS)scores higher,and incidence of postoperative complications lower in the HoLEP than in the TURP group(all P＜0.05).Conclusion:HoLEP is superior to TURP in improving the prostate function,oxidative stress indicators and sexual function of the patient with BPH.

Objective:To explore the repairing effects of 3D-printed nano-β-tricalcium phosphate (β-TCP) scaffolds loaded with vancomycin and bone morphogenetic protein-2 (BMP-2) for seawater -soaked tibial bone defects in rabbits. Methods:A total of 27 male New Zealand White rabbits were assigned to the normal group using a random number table method, with each group consisting of 9 rabbits. The rabbit tibial bone defect model was created using the osteotomy surgical method. Eight hours after operation, the wounds in the control group and seawater group were immersed in seawater for 2 hours, and those in the normal group were not immersed. After an observation period of 5-7 days, no significant redness or purulent discharge was observed in the wound appearance, then debridement was performed followed by corresponding implantations: the control group with gelatin sponges loaded with vancomycin and BMP-2, and the other two groups with 3D-printed nano-β-TCP scaffolds loaded with vancomycin and BMP-2. After filling the bone defects with the respective materials, all groups underwent layer-by-layer suturing of the wound, followed by disinfection with iodine and injection of gentamicin to prevent infection. The affected limbs were then immobilized using a plaster cast. The affected limbs were imaged using anteroposterior X-ray at 4, 8 and 16 weeks after operation, and the repair effects were evaluated using the Lane-Sandhu X-ray scoring system. At 16 weeks after operation, the bone defect tissues were collected for HE staining to observe bone tissue growth.Results:At 4 weeks after operation, the Lane-Sandhu X-ray score in the control group was significantly lower than that in the normal group [(2.8±1.1)points vs. (1.1±0.9)points] ( P<0.05), and that in the seawater group [(2.2±1.0)points] was not significantly different from those in the other two groups (all P>0.05). At 8 weeks after operation, the seawater group [(6.1±0.9)points] and the control group [(2.8±1.0)points] exhibited lower Lane-Sandhu X-ray score compared to the normal group [(8.2±1.0)points] (all P<0.05), and the seawater group showed a higher score compared to the control group ( P<0.05). At 16 weeks after operation, the control group [(3.8±1.0)points] exhibited a lower Lane-Sandhu X-ray score compared to the normal group [(10.0±1.3)points] and the seawater group [(9.3±1.2)points] (all P<0.05), while no significant difference was noted between the latter two ( P>0.05). At 16 weeks after operation, histological observations revealed varying degrees of bone tissue formation in three groups, with the normal group showing the best bone defect repair effect, followed by the seawater group. Conclusion:The 3D-printed nano-β-TCP scaffolds loaded with vancomycin and BMP-2 are effective for the treatment of seawater -soaked bone defects, which can promote bone tissue repair.
