Objective To systematically review the sex differences in efficacy of immune checkpoint inhibitors (ICIs) for non-small cell lung cancer (NSCLC) patients. Methods We conducted a computer search of Medline, The Cochrane Library, and EMbase from inception to November 2022 to identify randomized controlled trials (RCTs) assessing the efficacy of ICIs in patients with NSCLC. A meta-analysis was performed using RevMan 5.4 software. Results Finally 16 RCTs with a total of 9 653 patients were included, and the modified Jadad scale score was≥4 points. Meta-analysis results showed that in female NSCLC patients receiving immune therapy, the median overall survival (OS) [HR=0.72, 95%CI (0.61, 0.85), P<0.001] was longer than that in males [HR=0.73, 95%CI (0.69, 0.78), P<0.001]. Males [HR=0.64, 95%CI (0.58, 0.71), P<0.001] had an advantage over females [HR=0.76, 95%CI (0.57, 1.03), P=0.760] in median progression-free survival (PFS). Conclusion Females receiving ICIs have an advantage over males in terms of median OS. However, males tend to derive greater benefit from ICIs in terms of median PFS.

Systemic lupus erythematosus （SLE）， a refractory autoimmune disease， is among the dominant diseases where traditional Chinese medicine （TCM） shows advantages in the field of rheumatology and immunology. The China-Japan Friendship Hospital hosted the "46^th Youth Salon on Dominant Diseases （Systemic Lupus Erythematosus）" organized by the China Association of Chinese Medicine， which led to a consensus on "the advantages， challenges， interdisciplinary approaches， and translational achievements of integrated TCM and Western medical approaches in the diagnosis and treatment of SLE." The diagnosis and treatment of SLE currently face several challenges， such as frequent misdiagnosis and missed diagnosis in the early stages， difficulty in achieving treatment targets， multiple side effects from pharmacotherapy， and the lack of management strategies for special populations， all of which hinder the fulfillment of the clinical needs of patients. Integrated TCM and Western medical approaches can improve clinical symptoms such as skin erythema， aversion to cold and cold limbs， fatigue， dry mouth， restlessness， and heat sensation in the palms and soles， thereby improving patients' quality of life. The approaches also help consolidate the efficacy of conventional Western medicine， slow disease progression， reduce relapse rates， address multi-organ involvement， and prevent or treat complications. Additionally， they enhance efficacy and reduce toxicity， prevent the side effects of Western medications， help reduce hormone use， and offer distinct advantages in the individualized intervention of special populations， contributing to the whole-process management of the disease. However， evidence-based medical support for this integrated approach remains limited， and the quality of available evidence is generally low. Common evaluation systems and modern research methodologies should be adopted to clarify the efficacy of TCM in SLE treatment. Efforts should be made to carry out high-quality evidence-based medical research， strengthen the development of fundamental and pharmacological research， and further explain the distinct advantages of TCM in the diagnosis and treatment of SLE. Future efforts should focus on advancing the integration of TCM and modern medicine， incorporating multi-omics technologies， individualized stratification， and other precision medicine concepts， in combination with artificial intelligence. Moreover， interdisciplinary collaboration should be promoted to utilize modern technology in exploring the essence of TCM theories and screening effective formulae， thereby comprehensively improving the diagnosis and treatment of SLE through integrated TCM and Western medical approaches.

Objective: To explore the safety and feasibility of the disconnection of the left renal artery preferentially during robot-assisted inferior vena cava (IVC) thrombectomy for patients with left renal cell carcinoma and tumor emboli. Methods: Clinical data of 7 patients who underwent robot-assisted IVC thrombectomy and radical nephrectomy in the First Affiliated Hospital of Zhengzhou University during Dec.2021 and Oct.2024 were retrospectively analyzed.Thrombectomy was performed first，followed by nephrectomy. The “IVC-first, kidney-last”robotic technique was developed to minimize chances of IVC thrombus. When patients in left lateral decubitus position, the left renal artery was severed from the right side through the inferior vena cava and abdominal aorta. After removal of thrombus from IVC was completed, patients changed to the right lateral position to complete radical left nephrectomy. Results: Imaging examinations revealed that the median diameter of the renal cell carcinomas was 83(46-99) mm; the median length of the inferior vena cava cancerous emboli was 49(2-91) mm.According to the Mayo classification，the cancerous emboli were gradeⅠ in 2 cases，gradeⅡ in 4 cases，and grade Ⅲ in 1 case.All surgeries were successful.The median operation time was 248(201-331) minutes，blood loss 500(200-1000) mL，and 6 cases required intraoperative blood transfusion.The median time for transition into the intensive care unit was 1(1-4) days，and drainage tube removal 6(5-12) days.Serum creatinine increased significantly in 5 cases，4 of which returned to normal after 1 week，but 1 had renal insufficiency (creatinine 166 μmol/L).Chylous fistula occurred in 1 patient，and lower extremity venous thrombosis developed in 3 patients.Pathological examinations indicated 6 cases of renal cell carcinoma and 1 case of MiT family translocation renal cell carcinoma.During the median follow-up of 17(1-35) months，5 cases were tumor-free，while 2 had lung and retroperitoneal metastases.They received targeted therapy of axitinib combined immunotheraphy and lived with tumors. Conclusion: In the left lateral position for left renal cell carcinoma with cancerous emboli，robot-assisted laparoscopic thrombectomy by crossing the inferior vena cava and abdominal aorta and disconnecting the left renal artery first is safe and feasible.

AIM: To explore the clinical application effect of visual training equipment combined with conventional corrective treatment on children with ametropic amblyopia(AMA).METHODS: Prospective randomized control study. A total of 188 children(376 eyes)with AMA treated in our hospital from June 2021 to December 2022 were selected, and they were divided into two groups using a random number table. The conventional correction group(94 cases, 188 eyes)received conventional correction treatment, while the visual training group(94 cases, 188 eyes)received visual training equipment combined with conventional correction treatment, both lasted for 12 mo. The best corrected visual acuity, diopter, eye accommodation function, adverse reactions, amblyopia recurrence rates, and clinical efficacy were compared between the two groups at 6 and 12 mo after treatment.RESULTS:The two groups each had 8 cases(16 eyes)detached, the rate of loss to follow-up was 8.5%, and 86 cases(172 eyes)were included in each group. There were statistically significant differences in the best corrected visual acuity, diopter, amplitude of accommodation, accommodation facility and accommodative lag between the two groups of children before and after treatment(all P<0.05). The total effective rate of the visual training group(98.8%)was higher than that of the conventional correction group(91.9%; P<0.05). There was no statistically significant difference in the total effective rate of clinical efficacy between the two groups in different age groups and different degrees of amblyopia(all P>0.05). There was no statistically significant difference in the incidence of redness and swelling between the two groups(P>0.05). The recurrence rate of amblyopia in the visual training group(1.2%)was lower than that in the conventional correction group(8.1%; P<0.05).CONCLUSION: The combination of visual training equipment and conventional correction therapy has a significant clinical effect on children with AMA, which can effectively correct visual acuity, adjusting diopter and improve eye accommodation function, and recurrence rate of amblyopia is low and safety is high.

Objective To study the changes in serum autophagy markers in children with retinopathy of prematurity(ROP)and its clinical value.Methods Premature infants who were screened for ROP in our hospital from January 2020 to December 2022 were selected as the study subjects.Those screened out with ROP at 4-6 weeks of birth were assigned to the ROP group and those without ROP to the control group.The levels of serum autophagy markers LC3-Ⅱ,Beclin-1 and P62 were detected at the 3rd day,1st,2nd and 3rd weeks of birth.The two groups were compared in terms of serum autophagy markers.The diagnostic efficacy of serum autophagy markers on ROP was analyzed.Results There was no significant difference in serum LC3-Ⅱ,Beclin-1 and P62 levels between the ROP group and control group at the 3rd day of birth(P>0.05).At the first,second and third weeks of birth,how-ever,the ROP group showed significantly lower levels of serum LC3-Ⅱ and Beclin-1 but higher level of P62 com-pared to the control group(both P<0.05).The levels of serum LC3-Ⅱ,Beclin-1 and P62 at the first,second and third weeks of birth had diagnostic value for ROP.The children in the ROP group who did not receive mechanical ventilation and oxygen inhalation,and did not develop with sepsis and bronchopulmonary dysplasia showed lower serum LC3-Ⅱ and Beclin-1 levels and higher P62 levels at the first,second and third weeks of birth compared to those without the above-mentioned treatment as well as those complications(all P<0.05).In the ROP group,those with severe ROP showed lower serum LC3-Ⅱ and Beclin-1 levels and higher P62 levels at the 3rd day,and 1st,2nd and 3rd week of birth(all P<0.05).Conclusion The levels of serum autophagy markers in children with ROP show significant changes since the first week of birth,so they have diagnostic efficacy for the diseases.

Objective To investigate the effects of glutathiones-transferase (GST) T1, GSTM1 and epoxide hydrolase (EPHX1) genes on skin injury in workers exposed to coal tar pitch. Methods Workers from a carbon manufacturing company involved in coal tar pitch production and use were selected as the study subjects using a judgment sampling method. Workers with skin injury after exposed to coal tar were selected as the case group (55 cases), and those with the same workshop and type of work but without skin abnormalities were selected as the control group (197 cases). Urine and blood samples were collected from the workers, and levels of polycyclic aromatic hydrocarbon metabolites, including 1-pyrenol (1-OH-P), 1-naphthol (1-OH-N) and 2-naphthol (2-OH-N), in urine were measured using ultra high-performance liquid chromatography tandem mass spectrometry. The GSTT1, GSTM1 and EPHX1 genes in blood were detected by polymerase chain reaction. Results In the case group, all 55 workers reported skin stinging, 25 workers reported itching and flaking, and 15 workers reported blackheads and pigmentation. Urinary levels of 1-OH-N and 2-OH-N were lower in the worker in the case group than that in the control group (all P<0.05). However, there was no significant difference in the level of 1-OH-P between the two groups (P>0.05). There were significant differences in the number of workers with GSTT1, GSTM1 and EPHX1(His139His) genes between the two groups (all P<0.01). The GSTT1 and GSTM1 genes were positively correlated with post-shift urinary levels of 1-OH-N, 1-OH-P, and 2-OH-N (all P<0.01). The EPHX1 (139Arg locus) gene was positively correlated with post-shift 2-OH-N levels (P=0.03). The GSTT1, GSTM1, and EPHX1 (139Arg locus) genes were associated with reduced skin damage among coal tar workers (all P<0.01), after controlling for age, length of service, gender, smoking, and alcohol consumption. Conclusion Exposure to coal tar pitch can cause skin injury in workers, and the GSTT1, GSTM1, and EPHX1 (139Arg locus) genes are protective factors against skin injury in those workers.

Objective To establish a rapid screening method for 34 emerging contaminants in surface water by ultra-high performance liquid chromatography-quadrupole-time of flight mass spectrometry(UHPLC-Q-TOF-MS).Methods The pretreatment conditions of solid phase extraction(SPE)were op-timized by orthogonal experimental design and the surface water samples were concentrated and ex-tracted by Oasis? HLB and Oasis? MCX SPE columns in series.The extracts were separated by Kine-tex? EVO C18 column,with gradient elution of 0.1%formic acid aqueous solution and 0.1%formic acid methanol solution.Q-TOF-MS'fullscan'and'targeted MS/MS'modes were used to detect 34 emerging contaminants and to establish a database with 34 emerging contaminants precursor ion,prod-uct ion and retention times.Results The 34 emerging contaminants exhibited good linearity in the con-centration range respectively and the correlation coefficients(r)were higher than 0.97.The limit of de-tection was 0.2-10 ng/L and the recoveries were 81.2%-119.2%.The intra-day precision was 0.78%-18.70%.The method was applied to analyze multiple surface water samples and 6 emerging contaminants were detected,with a concentration range of 1.93-157.71 ng/L.Conclusion The method is simple and rapid for screening various emerging contaminants at the trace level in surface water.

Objective To investigate the clinical efficacy of transjugular intrahepatic portosystemic shunt(TIPS)combined with indwelling catheter-directed thrombolysis for the treatment of portal vein thrombosis(PVT).Methods The clinical efficacy of 307 patients with portal hypertension complicated by PVT,who received successful TIPS combined with indwelling catheter-directed thrombolysis at the Affiliated Beijing Shijitan Hospital of Capital Medical University of China between January 2016 and December 2019,were retrospectively analyzed.Before and after TIPS,the inferior vena cava pressure(IVCP)and portal vein pressure(PVP)were measured,and the pre-TIPS,post-TIPS(before thrombolysis),and post-thrombolysis portal pressure gradient(PPG,PPG=PVP-IVCP)was separately calculated.Reexamination of portal venography DSA was performed to determine the degree of PVT disappearance and whether the shunt was unobstructed.All patients were followed up for one year.Results The pre-TIPS,post-TIPS(before thrombolysis),and post-thrombolysis mean PPG was(24.50±6.91)mmHg,(18.51±5.11)mmHg,and(10.17±3.97)mmHg,respectively.The post-thrombolysis mean PPG was strikingly lower than the pre-thrombolysis values,the differences were statistically significant(P＜0.001).Among the 307 patients,complete disappearance of PVT was observed in 221(72.3%),remarkable reduction of PVT in 86(27.7%),and no invalid result was seen.The patients having complete patency of the shunt flow accounted for 85.7%of the 307 patients(261/307),and the patients having partial patency of the shunt flow accounted for 14.3%of the 307 patients(46/307).Forty-two patients developed complications,and no death occurred.All patients were followed up for one year,and the main clinical symptoms were improved or completely disappeared.Among the 307 patients,an increase in thrombus volume was found in 17(5.5%)when compared to their postoperative values,which returned to the first-time postoperative level after local treatment of the thrombus via the TIPS shunt combined with catheter-directed thrombolysis.Within one year after TIPS and thrombolysis,overt hepatic encephalopathy(OHE)occurred in 54 patients(17.6%,54/307).One patient died of hepatic failure 9 months after TIPS,another patient died of cerebral hemorrhage 11 months after TIPS,and all the remaining patients were alive.Conclusion For patients with portal hypertension complicated by PVT,TIPS combined with indwelling catheter-directed thrombolysis is clinically safe and effective.The standardized,systematic management of the whole therapeutic process should be strengthened.(J Intervent Radiol,2024,32:22-27)

Objective To investigate the effects of different culture conditions(RPMI-1640,DMEM and DMEM/F12 medium)on the passage of MPM cells isolated from the tissues of Malignant pleural mesothelioma(MPM),and to study the effects of CDKN2B on the proliferation,invasion and apoptosis of MPM cells.Methods MPM cells were isolated from MPM tissues and cultured in RPMI-1640,DMEM and DMEM/F12 medium,respectively.Cell proliferation was examined by CCK-8,and the nuclei and chromosomes were observed by Wright-Giemsa staining.Fluorescence intensities of Calretinin,CD141,CK5,EMA and WT-1 were conducted by immunofluorescence assay.The mRNA and protein expression of CDKN2B were detected by RT-qPCR and Western blot,respectively.Transwell was used to detect cell invasion and flow cytometry was used to detect cell apoptosis.Results The established MPM cells showed good viability when passaged to the 10th generation in RPMI-1640,DMEM and DMEM/F12 cultures,and the MPM markers Calretinin,CD141,CK5,EMA and WT-1 were all expressed in the cells.The viability of MPM cells in RPMI-1640 culture medium was relatively stable.CDKN2B was downregulated in MPM cells(P<0.05),and overexpression of CDKN2B significantly suppressed the proliferation(P<0.05),invasion(P<0.05)and epithelial interstitial transformation of MPM cells(P<0.01),and promoted the apoptosis(P<0.01).Conclusion The established MPM cells were stably passaged in RPMI-1640 culture medium,and CDKN2B may be a potential target for the diagnosis and treatment of MPM.
