Abstract
N6-methyladenosine (m6A) is considered to be the most common and abundant epigenetics modification in messenger RNA (mRNA) and noncoding RNA. Abnormal modification of m6A is closely related to the occurrence, development, progression, and prognosis of cancer. m6A regulators have been identified as novel targets for anticancer drugs. Natural products, a rich source of traditional anticancer drugs, have been utilized for the development of m6A-targeting drugs. Here, we review the key role of m6A modification in cancer progression and explore the prospects and structural modification mechanisms of natural products as potential drugs targeting m6A modification for cancer treatment.

Abstract
BACKGROUND The significant clinical benefits of PD-1/PD-L1 immune checkpoint inhibitors (ICIP) in non-small cell lung cancer (NSCLC) have been widely recognized, emphasizing the urgent need for a reliable biomarker. In this study, we find the remarkable capacity of tumor mutational burden (TMB) to serve as an accessible and streamlined indicator. PATIENTS AND METHODS We designed a retrospective cohort study, consisting of 600 NSCLC patients treated with ICIP. Association between TMB and overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR) has been explored. RESULTS A strong positive correlation between TMB levels and OS, PFS rates, clinical benefit has been found when TMB > = 16(TMB > = 16 mutations/megabase (mut/Mb)). However, when TMB < 16, increasing TMB values did not exhibit a gradual stepwise increase in OS and PFS rates. The median months of OS in the TMB > = 16 and < 16 are 35.58, and 10.71 months respectively with average 12.39 months (p < 0.0001). The median months of PFS in the TMB > = 16 and < 16 are not-obtained, and 2.79 months respectively with an average of 3.32 months (p < 0.0001). The DCR in the TMB > = 16 and < 16 are 71.4% and 44.2% respectively with an average of 47.7% (p < 0.0001). The ORR in the TMB > = 16 and < 16 are 49.4% and 20.8% respectively with an average of 24.5% (p < 0.0001). CONCLUSION The TMB > = 16 shows significantly associated with optimal ICIP treatment outcomes, including higher patient survival rates, delayed disease progression, and significant clinical benefits. These results present the potential of TMB as a promising biomarker candidate for NSCLC patients undergoing ICIP treatment.

Abstract
Objective: To assess the efficacy and safety of modified Hartel approach in the treatment of primary trigeminal neuralgia with radiofrequency thermocoagulation. Methods: A total of 89 patients with primary trigeminal neuralgia in Nanjing Drum Tower Clinical College of Xuzhou Medical University from July 2021 to July 2022 were prospectively included, and were divided into experimental group (n=45, modified Hartel approach: selecting 2.0 cm lateral to and 1.0 cm below angulus oris as insertion point) and control group (n=44, traditional Hartel approach: selecting 2.5 cm lateral to the angulus oris as insertion point) according to the random number table method. There were 19 males and 26 females in the experimental group, and aged (67.6±8.8) years. Meanwhile, there were 19 males and 25 females in the control group, and aged (64.8±11.7) years. All the patients were treated by CT-guided radiofrequency thermocoagulation. The success rate of one-time puncture, number of punctures, the time of puncture, operation time, numerical rating scale (NRS) scores and complications were recorded and compared between the two groups. Results: The success rate of one-time puncture in experimental group was 64.4% (29/45), which was higher than that in control group 31.8% (14/44) (P<0.05). The number of punctures [M (Q1, Q3)], the time of puncture [M (Q1, Q3)] and operation time in the experimental group were 1 (1, 2), 218 (206, 378) s, (19.9±2.7) min, which were less than those of control group [2 (1, 3), 390 (231, 598) s, (27.0±3.9) min] (all P<0.05). The NRS scores [M (Q1, Q3)] of 1 day, 1 month and 3 months after surgery in the experimental group were 1 (1, 2), 1 (0, 2) and 1(0, 1), respectively, which were lower than the baseline level [6 (6, 7)] (all P<0.05). The NRS scores [M (Q1, Q3)] of 1 day, 1 month and 3 months after surgery in the control group were 1 (1, 2), 1 (0, 2) and 1 (0, 2), respectively, which were lower than the baseline level [6 (6, 7)] (all P<0.05). There was no statistically significant difference in the incidence of nausea and vomiting, facial numbness, and decreased masticatory muscle strength between the two groups (all P>0.05) In the experimental group, two patients had puncture needles into the oral cavity, with timely detection and replacement of puncture needles, and no infection occurred. There was no cerebrospinal fluid leakage and decreased corneal reflex in both groups. Conclusion: The modified Hartel approach can significantly improve the success rate of one-time puncture via foramen ovale, reduce the operation time and the incidence of postoperative facial swelling, which is a safe and effective puncture method.

Abstract
Objective: To evaluate the accuracy, efficacy and safety of 3D-printed personalized navigation template in the treatment of thoracic postherpetic neuralgia (PHN) with dorsal root ganglion pulsed radiofrequency (DRG-PRF). Methods: A total of 63 patients with thoracic PHN from March 2019 to December 2020 in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School were enrolled and randomly divided into study group (n=31) and control group (n=32) by random number table method. The study group received DRG-PRF treatment assisted by 3D-printed navigation template, while the control group received DRG-PRF treatment guided by conventional CT. The one-time success rate of puncture, the incidence of puncture times ≥3, the number of punctures, puncture time, visual analogue scale (VAS) score and surgical complications between the two groups were compared. Results: The one-time success rate of puncture in study group was 84.9% (79/93), which was higher than that of control group [30.2% (29/96)] (P<0.001). The incidence of puncture times ≥3, the number of punctures, puncture time in study group were 4.3% (4/93), 1 (1, 1) and 2.9 (2.8, 3.0) min, respectively, which were lower than that of the control group [21.9% (21/96), 2(1, 3), 9.0 (4.5, 12.9) min, respectively] (all P<0.01). No difference was found in VAS score at each time point before and after surgery between the two groups (all P>0.05). There was one case of pleura puncture in the control group, but no other complications such as straying into vertebral canal, hematoma, spinal cord injury, limb movement disorder, infection were found in the two groups. Conclusions: 3D-printed personalized navigation template is an effective method to guide DRG-PRF for the treatment of thoracic postherpetic neuralgia. It can significantly improve the surgical efficiency of DRG-PRF, but has no significant effect on the surgical efficacy.

Abstract
Cerebrovascular disease such as stroke is one of the most common diseases in the aging population, and neural stem cells (NSCs) transplantation may provide an alternative therapy for cerebral ischemia. However, a hostile microenvironment in the ischemic brain offers is challenging for the survival of the transplanted cells. Considering the neuroprotective role of basic fibroblast growth factor (bFGF), the present study investigated whether bFGF gene-modified NSCs could improve the neurological function deficit after transient middle cerebral artery occlusion (MCAO) in adult male Sprague-Dawley rats. These rats were intravenously injected with modified NSCs (5×106/200 μL) or vehicle 24 h after MCAO. Histological analysis was performed on days 7 and 28 after tMCAO. The survival, migration, proliferation, and differentiation of the transplanted modified C17.2 cells in the brain were improved. In addition, the intravenous infusion of NSCs and bFGF gene-modified C17.2 cells improved the functional recovery as compared to the control. Furthermore, bFGF promoted the C17.2 cell growth, survival, and differentiation into mature neurons within the infarct region. These data suggested that bFGF gene-modified NSCs have the potential to be a therapeutic agent in brain ischemia.

Abstract
BACKGROUND Anterior cervical discectomy and fusion (ACDF) was almost the "golden standard" technique in treatment of symptomatic cervical degenerative disc disease, however, it cause motion loss of the indexed level, increase the intradiscal pressure and motion of the adjacent levels, and may accelerate the degeneration of adjacent level. Cervical disc arthroplasty (CDA) was designed to preserve the motion of index level, avoid the over-activity of adjacent levels and reduce the degeneration of adjacent disc levels, the process of degeneration of adjacent level is very slowly, long term follow up studies should be conducted, this study aim to compare the more than 5 years' long-term clinical outcomes and safety between CDA and ACDF. METHODS A systematic review and meta-analysis that will be performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The electric database of Medline, Embase, and Cochrane library will be systematic search. A standard data form will be used to extract the data of included studies. We will assess the studies according to the Cochrane Handbook for Systematic Reviews of Interventions, and perform analysis in software STATA 12.0. Fixed-effects models will be used for homogeneity data, while random-effects will be used for heterogeneity data. The overall effect sizes will be determined as weighted mean difference (WMD) for continuous outcomes and Relative risk (RR) for dichotomous outcomes. RESULTS The results of study will be disseminated via both international conference and peer-review journal. CONCLUSION The conclusion of our study will provide the long-term and updated evidence of clinical outcomes and safety between CDA and ACDF, and help surgeon to change better surgical technique for patients.
