ABSTRACT
Objective: To retrospectively analyze the clinical characteristics and prognosis of 85 newly diagnosed patients with follicular lymphoma (FL), as well as the prognostic value of comprehensive geriatric assessment (CGA) in patients with FL aged ≥ 60 years old. Methods: The clinical data and prognosis of 85 newly diagnosed FL patients admitted from August 2011 to June 2022 were collected. The clinical features, laboratory indicators, therapeutic efficacy, survival and prognostic factors of patients were statistically analyzed, and the prognosis of patients was stratified using various geriatric assessment tools. Results: â The patients with FL were mostly middle-aged and older, with a median age of 59 (20-87) years, including 41 patients (48.2%) aged ≥60 years. The ratio of male to female was 1â¶1.36. Overall, 77.6% of the patients were diagnosed with Ann Arbor stage â ¢-â £, and 17 cases (20.0%) were accompanied by B symptoms. Bone marrow involvement was the most common (34.1%). â¡Overall, 71 patients received immunochemotherapy. The overall response rate was 86.6%, and the complete recovery rate was 47.1% of 68 evaluated patients. Disease progression or relapse in the first 2 years was observed in 23.9% of the patient. Overall, 14.1% of the patients died during follow-up. â¢Of the 56 patients receiving R-CHOP-like therapies, the 3-year and 5-year progression-free survival (PFS) rates were 85.2% and 72.8%, respectively, and the 3-year and 5-year overall survival (OS) rates were 95.9% and 88.8%, respectively. The univariate analysis showed that age ≥60 years old (HR=3.430, 95% CI 1.256-9.371, P=0.016), B symptoms (HR=5.030, 95% CI 1.903-13.294, P=0.016), Prognostic Nutritional Index (PNI) <45.25 (HR=3.478, 95% CI 1.299-9.310, P=0.013), Follicular Lymphoma International Prognostic Index (FLIPI) high-risk (HR=2.918, 95% CI 1.074-7.928, P=0.036), and PRIMA-prognostic index (PRIMA-PI) high-risk (HR=2.745, 95% CI 1.057-7.129, P=0.038) significantly predicted PFS. Moreover, age ≥60 years old and B symptoms were independent risk factors for PFS. Progression of disease within 24 months (POD24) significantly predicted OS in the univariate analysis. Conclusions: FL is more common among middle-aged and older women. Age, B symptoms, PNI score, FLIPI high-risk, PRIMA-PI high-risk, and POD24 influenced PFS and OS. The CGA can be used for treatment selection and risk prognostication in older patients with FL.

Objective: To examine the postoperative prosthesis-related complications, short-term surgical outcomes and patient satisfaction with breast reconstruction between patients who underwent endoscopic assisted versus conventional nipple sparing mastectomy and immediate prothesis breast reconstruction. Methods: This study was a retrospective cohort study. A retrospective analysis was performed on clinical data of 104 women with breast cancer who received nipple sparing mastectomy and immediate prothesis breast reconstruction from August 2021 to August 2022 at the Breast Tumor Center, Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University. They were divided into two groups according to the surgical approach. A total of 53 patients, aged (43.3±9.9) years (range: 25 to 66 years), underwent endoscopic nipple sparing mastectomy (E-NSM group) and immediate prothesis breast reconstruction. The other 51 patients aged (39.9±7.8) years (range: 25 to 54 years) underwent conventional open surgery (C-NSM group). Short-term surgical outcomes including operation time, postoperative hospital stay, postoperative blood loss, and postoperative drainage volume in 2 days were recorded. Patient satisfaction with breast reconstruction was compared using the Wilcoxon rank sum test. Postoperative prothesis-related complications were investigated to determine the experience to deal with them. Results: No postoperative prosthesis-related infection, prosthesis loss, or necrosis of the nipple-areola complex occurred in the E-NSM group, while 1 patient suffered from hematoma, whose wound was skinned with resuture after disinfection. Five patients in the C-NSM group had prosthesis-related infection, 2 of them received prosthesis removal surgery combined with sufficient antimicrobial agent, another one underwent surgery for subcutaneous placement of the drain, as well as antimicrobial agent therapy, and the rest of them healed up only with antimicrobial agent therapy. All recovered well after treatment. One patient recovered from necrosis of the nipple-areola complex through periodic iodophor disinfection and dressing which ended in improvement of necrotic areas, another patient who had hematoma accepted the same treatment mentioned above and also healed. All the patients mentioned above are now in stable conditions. Patients in the E-NSM group had higher satisfaction with the cosmetic results of the breast prosthesis implant than those in the C-NSM group (Z=-4.511, P<0.01). Conclusions: Both surgical approaches were proven to be safe and effective with a low rate of postoperative prosthesis-related complications. Patients in the E-NSM group were more satisfied with the cosmetic results of breast reconstruction than those in the C-NSM group.

Spin-dependent transport in ferromagnet/organic-ferromagnet/ferromagnet junctions is investigated theoretically under different alignment of magnetization orientations. The results demonstrate a significant current rectification at low bias voltages, and the rectifying direction relies on the relative magnetization orientation in each component. The orbital analysis demonstrates two underlying mechanisms for the rectification, the slight structural asymmetry of the molecule from spin radicals and distinct spin match between conducting electrons and the magnetic molecule upon the reversal of bias. The latter is responsible for the strong low-bias rectification and relies on the magnetization alignment. The effects of parameter strength, temperature and size on the rectification are discussed. This work explores a new route to achieve high-performance molecular rectifiers operating at low bias with controlled rectifying direction.
ABSTRACT
Objective: To investigate the clinical value of the novel approach,radical resection of the retroperitoneal lipo-lymphatic layer (RRRLLL),in the surgical treatment of resectable pancreatic head cancer. Methods: Between June 2020 and June 2022,a total of 221 patients with pancreatic head cancer underwent surgical treatment using the RRRLLL approach(RRRLLL group),while 107 patients received traditional surgical treatment(traditional group) in five high-volume pancreatic centers in China. Data from surgical technique and clinical perioperative outcomes,including lymph node harvested,surgical time,and complications,were analyzed. The RRRLLL group consisted of 144 males and 77 females with an age of (67.5±9.0) years(range:41.3 to 81.1 years). The traditional group included 71 males and 36 females,with an age of (66.3±8.1) years(range:45.1 to 79.2 years). Statistical analysis was performed using the K-S test,Z test,or χ2 test. Results: Pancreaticoduodenectomy was performed successfully in all patients,achieving R0 resection. RRRLLL group surgery required mobilization of retroperitoneal adipose and lymphatic tissues starting from the right edge of the inferior vena cava and extending to the left side,up to the superior mesenteric artery,down to the inferior mesenteric artery,and left to the left side of the aorta,including the perineural and lymphatic tissues around the superior mesenteric artery and the sheath of the mesenteric artery. However,the traditional group did not include the areas mentioned above in the scope of clearance. There were no statistically significant differences between the RRRLLL group and the traditional group in terms of age,sex,tumor size,T stage,and vascular invasion (all P>0.05). However,the number of lymph nodes harvested in the RRRLLL group was significantly higher at 28.7±9.0 (range: 18 to 39) compared to 18.2±8.0 (range: 12 to 21) in the traditional group (Z=-10.691,P<0.05). There were no statistically significant differences in the number of positive lymph nodes,N staging,and postoperative complications between the two groups. Conclusion: The RRRLLL approach improved lymph node dissection compared to the traditional approach,potentially leading to reduced recurrence rates.
ABSTRACT
Hepatocellular carcinoma(HCC) is one of the most common malignancies of the digestive system,which is prone to be associated with microvascular or macrovascular invasion. Among them,HCC with inferior vena cava tumor thrombus(IVCTT) or right atrium tumor thrombus(RATT) is rare and has a poor prognosis. However,surgical treatment of HCC with IVCTT and (or) RATT is rarely reported and summarized. The review described the classification of HCC tumor thrombus with IVCTT and (or) RATT, summarized the progress of surgical approaches and surgical operations,and introduced a case of thrombectomy after pushing from the outer surface of the atrium,rendering the RATT to the inferior vena cava under non-cardiopulmonary bypass. The review also proposed the prospective treatments for HCC with IVCTT or RATT,providing clinical guidance to hepatobiliary surgeons.

Objective: To improve the awareness of hemophagocytic syndrome(HPS) secondary to COVID-19 (COVID-sHPS). Methods: We reported an adult case of COVID-sHPS, including clinical presentation, laboratory examinations, histopathological findings, treatment strategy, and outcome. We also conducted literature research in PubMed database and Wanfang database using the keywords "COVID-19" and "hemophagocytic syndrome" and subsequently summarized relevant literature. Results: A 49-year-old man was admitted to our hospital after 4 weeks of recurrent fever. Prior to this hospitalization, he had received an empiric combination therapy with antibiotics and antiviral drugs against SARS-CoV-2. His vital signs were within the normal range and no abnormalities were found on physical examination on admission. After admission, throat swab nucleic acid tests were weakly positive for SARS-CoV-2, and negative for influenza and respiratory syncytial virus. Blood nucleic acid tests for cytomegalovirus and EB virus were negative, as was blood mNGS. Laboratory tests showed a series of abnormalities, including leukopenia, thrombocytopenia, low fibrinogen, elevated serum ferritin, elevated transaminase, decreased NK cell activity, and hemophagocytosis in bone marrow. According to the HPS-2004 diagnostic criteria, he was diagnosed with hemophagocytic syndrome, which was high likely to be caused by COVID-19 infection due to the lack of evidence of genetic risk factors and other clear triggers. He was initially treated with dexamethasone at a dose of 10 mg·m-2·d-1 and his condition improved rapidly. The literature search identified twenty-three articles on COVID-sHPS, 22 of which were in English. A total of 89 patients had COVID-sHPS and 55 (61.7%) were male. COVID-sHPS could occur at any age, but mainly in adults (86/89, 96%). Fever was reported in the literature with a clear description of the course of the disease. Most HPS occurred during the acute phase of COVID-19, but 3 patients developed HPS during the convalescent phase. Almost all reported cases presented with increased ferritin, elevated transaminases, elevated triglycerides, and cytopenia, mainly anemia and thrombocytopenia. In the retrieved literature, HS-score≥169 was frequently used to diagnose COVID-sHPS, and glucocorticoid in combination with immunoglobulin was the most common treatment strategy. COVID-sHPS had a poor prognosis and a high mortality rate (84.2%, 75/89). Conclusions: The prognosis of COVID-sHPS is poor, so clinicians should raise their awareness of the disease, identify high-risk suspected populations, and arrange reasonable relevant examinations for definite diagnosis and early initial treatment to improve their outcome.

Patients with intrahepatic cholangiocarcinoma have a poor overall prognosis and a low long-term survival rate. Currently, multimodal treatment is the mainstay of treatment, and surgical resection is the most important treatment for patients with intrahepatic cholangiocarcinoma for a long-term survival. Although the treatment strategies have been constantly updated in recent years to improve survival rates, there are still many controversial issues in the existing treatment strategies. Based on our center's clinical practice and recent research progress, analyzes several issues affecting long-term survival were analyzed based on three aspects: accurate clinical assessment methods, the related decisions making for surgical resection, and the strategies of precision medicine.

Nephronophthisis (NPHP) is a common pediatric cystic kidney disease, accounting for approximately 10% of end-stage renal failure cases in children. NPHP is primarily diagnosed through the identification of indel mutations and copy number variants (CNVs), and patients carrying NPHP1 mutations usually progress to renal failure at a mean age of 13 years old. However, the association between CNVs containing NPHP1 variations and the progression of NPHP-induced disease remains unclear. Here, we report three NPHP patients in a family. The proband had developed stage 4 chronic kidney disease (CKD) at 9 years old, and her younger brother and older sister had developed renal failure at 8 and 10 years old, respectively. A genetic diagnosis showed that they carried two rare CNVs, including homozygous loss of NPHP1, MALL, ACTR1AP1, MTLN, and LOC100507334. Heterozygous deletions mainly consisted of non-coding RNA genes on both sides of the CNVs. The proband was in stage 4 of CKD while her brother had progressed to renal failure, probably due to more extensive heterozygous deletion of a 67.115 kbp fragment, which included LIMS3-LOC440895, LOC440895, GPAA1P1, ZBTB45P1, and LINC0112 genes. This report demonstrates that larger CNV deletions, including homozygous NPHP1, MALL, and MTLN mutations and heterozygous deletions, presumably accelerate disease progression. Therefore, early genetic diagnosis plays a crucial role in the intervention and prognosis of these patients.

Objective: To investigate the surgical indications and perioperative clinical outcomes of pelvic exenteration (PE) for locally advanced, recurrent pelvic malignancies and complex pelvic fistulas. Methods: This was a descriptive study.The indications for performing PE were: (1) locally advanced, recurrent pelvic malignancy or complex pelvic fistula diagnosed preoperatively by imaging and pathological examination of a biopsy; (2)preoperative agreement by a multi-disciplinary team that non-surgical and conventional surgical treatment had failed and PE was required; and (3) findings on intraoperative exploration confirming this conclusion.Contraindications to this surgical procedure comprised cardiac and respiratory dysfunction, poor nutritional status,and mental state too poor to tolerate the procedure.Clinical data of 141 patients who met the above criteria, had undergone PE in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to September 2022, had complete perioperative clinical data, and had given written informed consent to the procedure were collected,and the operation,relevant perioperative variables, postoperative pathological findings (curative resection), and early postoperative complications were analyzed. Results: Of the 141 included patients, 43 (30.5%) had primary malignancies, 61 (43.3%) recurrent malignancies, 28 (19.9%) complex fistulas after radical resection of malignancies,and nine (6.4%)complex fistulas caused by benign disease. There were 79 cases (56.0%) of gastrointestinal tumors, 30 cases (21.3%) of reproductive tumors, 16 cases (11.3%) of urinary tumors, and 7 cases (5.0%) of other tumors such mesenchymal tissue tumors. Among the 104 patients with primary and recurrent malignancies, 15 patients with severe complications of pelvic perineum of advanced tumors were planned to undergo palliative PE surgery for symptom relief after preoperative assessment of multidisciplinary team; the other 89 patients were evaluated for radical PE surgery. All surgeries were successfully completed. Total PE was performed on 73 patients (51.8%),anterior PE on 22 (15.6%),and posterior PE in 46 (32.6%). The median operative time was 576 (453,679) minutes, median intraoperative blood loss 500 (200, 1 200) ml, and median hospital stay 17 (13.0,30.5)days.There were no intraoperative deaths. Of the 89 patients evaluated for radical PE surgery, the radical R0 resection was achieved in 64 (71.9%) of them, R1 resection in 23 (25.8%), and R2 resection in two (2.2%). One or more postoperative complications occurred in 85 cases (60.3%), 32 (22.7%)of which were Clavien-Dindo grade III and above.One patient (0.7%)died during the perioperative period. Conclusion: PE is a valid option for treating locally advanced or recurrent pelvic malignancies and complex pelvic fistulas.

Objective: To explore the relationship between gene polymorphism of killer cell immunoglobulin-like receptor (KIR) and its ligand-specific human leukocyte antigen C (HLA-C) and Graves' disease (GD). Methods: Case-control study. A total of 118 unrelated GD patients (GD group) admitted to Shandong Provincial Hospital from January 2011 to December 2017 and 108 age-and sex-matched healthy controls (healthy control group) were included. The KIR genotype and its ligand HLA-C allele were detected by polymerase chain reaction sequence-specific primers (PCR-SSP). The distribution of KIR/HLA-C gene combination in GD patients and control population was analyzed to explore its association with the occurrence of GD. Results: In GD group, there were 29 males and 89 females, aged (38±14) years. In the healthy control group, there were 28 males and 80 females, aged (37±13) years. Compared with the healthy control group, the occurrence frequency of HLA-Cw01 was higher in GD group[36.4%(43/118) vs 18.5%(20/108), P=0.003], and the occurrence frequency of HLA-Cw03 and HLA-Cw06 was lower in GD group[11.9%(14/118) vs 39.8%(43/108), P<0.001; 9.3%(11/118) vs 18.5%(20/108), P=0.045]. The frequency of KIR2DL1/HLA-C2 gene combination in GD group was lower than that in control group [17.8%(21/118) vs 34.3%(37/108), P=0.005]. Logistic regression analysis showed that KIR2DL1/HLA-C2 gene combination was a protective factor for GD occurrence (OR=0.308, 95%CI: 0.126-0.752, P=0.010). Conclusions: The polymorphism of KIR/HLA-C gene is related to GD. The low expression of KIR2DL1/HLA-C2 in GD patients may be a protective factor for GD.

Objectives: To examine the efficacy of terminal branches portal vein embolization(TBPVE) for the increment of FLR in hepatocellular carcinoma (HCC) patients and to introduce its clinical value with transcatheter chemoembolization(TACE) in the treatment of HCC patients without surgery. Methods: One hundred and fifty HCC patients from three clinical centers of china underwent TBPVE technique from December 2016 to May 2021,including 89 males and 61 females. The average age was 51.9 years(range:18 to 79 years).One hundred and one patients were diagnosed with a background of HBV infection,including 27 patients with portal venous hypertension.TACE was performed simultaneously with TBPVE in 102 patients.Fifty-three patients underwent hepatectomy,who were subdivided into HBV positive and HBV negative groups,with TACE and without TACE groups to analyze the increment of future liver remnant (FLR), complications and survival data.These data were also analyzed in other 97 patients without hepatectomy. Results: All the patients reached adequate FLR successfully in 14 days after TBPVE including patients with portal venous hypertension.The average increment rates of FLR was 56.2% in 7 days and 57.8% in 14 days after TBPVE. There was no significant difference neither between HBV positive and HBV negative groups(7 days:(55.0±27.3)% vs.(57.8±20.9)%,t=0.885,P=0.373; 14 days:(57.3±24.6)% vs.(58.3±23.7)%;t=0.801,P=0.447),or between with TACE and without TACE groups(7 days:(62.3±26.3)% vs. (48.8±20.6)%;t=1.788,P=0.077;14 days:(64.4±25.0)% vs.(55.2±23.1)%;t=1.097,P=0.257).The morbidity and mortality rates were 20.8% and 1.9% in patients with hepatectomy.The 1-,3-year overall survival(OS) and disease-free(DFS) rates were 87.5%,64.5% and 64.7%,40.6% for patients underwent surgery.There was no significant difference of 1-,3-year OS and DFS between HBV positive and negative groups,but there were different between TACE and without TACE groups.The 1-,3-year OS for patients underwent TBPVE and TACE but without surgery were 80.1%, 53.7%. Conclusion: TBPVE is a good alternative technique for modulation of FLR for staged hepatectomy even in HBV positive HCC patients and can be applied with TACE procedure simultaneously as an option treatment for patients with no intend to surgery.

Objective: To explore the feasibility and clinical value of a new classification for resectable intrahepatic cholangiocarcinoma (IHCC) according to the actual anatomy. Methods: The data of 135 patients with IHCC who were admitted to the Department of Hepatopancreatobiliary Surgery,Second Affiliated Hospital of Zhejiang University School of Medicine from November 2011 to November 2020 after discussion by a multidisciplinary team and planned to undergo radical resection were analyzed retrospectively. There were 77 males and 58 females,with a median age of 61 years (range:26 to 86 years),of which 38 cases had vascular invasion. This new classification was carried out independently by two hepatobiliary surgeons. First,a preliminary classification was made based on the location of the tumor,and then the final classification was based on vascular invasion. All patients were followed up by telephone,and the follow-up was as of November 2020. Survival time is defined as the time after surgery to follow-up or death. Log-rank test was used to compare patients' median recurrence-free survival and overall survival time. The Cox proportional hazard model was used to analyze the prognosis factors of the overall survival time of patients with IHCC. Results: Among the 135 patients,129 underwent R0 resection and 6 underwent R1 resection. According to the actual anatomy,28 cases (20.7%) belonged to segmental type, 43 cases (31.9%) belonged to branch type, 64 cases (47.4%). The median survival time of all patients was 35.2 months(95%CI:21.3 to 70.5 months),the 1-year cumulative survival rate was 75.1%,the 3-year cumulative survival rate was 45.8%,and the 5-year cumulative survival rate was 39.0%. After grouping according to the classification,the median survival time of segmental patients was 36.9 months (more than 50% of patients reached the median survival time),and the median survival time of branched patients was 33.8 months (95%CI:16.8 to 38.5);The median survival time of lobe patients was 25.0 months (95%CI:13.6 to 58.7). The result of Log-rank test between groups indicated that the median survival time of patients with segmental type was better than that of patients with branch and lobe type(HR=2.03,95%CI:1.24 to 3.64,P=0.006);There was no significant difference in survival time between patients with branch type and lobe type (P=0.685). The results of the multivariate analysis of the Cox risk ratio model suggested that the actual anatomical location classification (HR=2.32,95%CI:1.10 to 4.92,P=0.028) and the postoperative lymph node metastasis rate (HR=2.06,95%CI:1.24 to 3.45,P=0.005) were independent factors related to survival after radical resection of IHCC patients. Conclusion: It is simple and convenient to classify resectable IHCC by actual anatomy,which can be used to preliminarily judge the prognosis of patients and provide a feasible classification scheme for the clinic.

Objective: To evaluate the prognostic effects of two comprehensive geriatric assessment (CGA) methods in elderly patients with acute myeloid leukemia (AML). Methods: Ninety-seven patients with newly diagnosed AML at Beijing Hospital from August 2008 to December 2019 were included (≥60 years old). All patients were evaluated by two methods of CGA. One was IACA index proposed by Beijing Hospital, including instrumental activities of daily living (IADL), age, Charlson comorbidity index (CCI), albumin; the other was proposed by Italian FIL study group (FIL-CGA), including activities of daily living (ADL), IADL, age, and modified cumulative illness rating score for geriatrics (MCIRS-G). Results: Among 97 patients, 54 patients received standard chemotherapy, 16 with decitabine, 2 with targeted therapy and 25 with the best supportive therapy. The overall response rate (ORR) in 72 treated patients were 67.7%, 33.3% and 0 respectively in fit, unfit and frail groups according to IACA index (P=0.001). Based on FIL-CGA, the ORRs of fit, unfit and frail groups were 52.5%, 41.7% and 35.0% respectively (P=0.418). The 1-year OS rates of fit, unfit and frail groups regarding IACA method were 78.7%, 27.7% and 0 respectively (P<0.01). The 1-year OS rates of fit, unfit and frail groups regarding FIL-CGA method were 67.8%, 28.2% and 13.9% respectively (P<0.01), while no significant difference was seen between unfit group and frail group (P=0.111). The early death rates of fit, unfit and frail groups by IACA were 0, 6.0% and 28.6% respectively (P=0.006), while those by FIL-CGA were 2.3%, 5.9%, 13.9% respectively (P=0.123). Conclusion: Compared with FIL-CGA method, IACA predicts more effectively the treatment response, survival and early mortality in elderly patients with AML.

INTRODUCTION: This study aimed to provide information about the clinical and physiochemical effects of pill splitting training in elderly cardiac patients in Hong Kong. METHODS: A parallel study design was adopted. Patients taking lisinopril, amlodipine, simvastatin, metformin, or perindopril who needed to split pills were recruited from the Prince of Wales Hospital. Patients were divided into two groups at their first visit. Patients in group A split drugs using their own technique, whereas patients in group B used pill cutters after relevant training until their next follow-up visit. The primary outcome was the change in drug content between before and after the pill splitting training. Assays were performed to determine the drug content. Secondary outcomes were the changes in clinical outcomes, patients' attitudes and acceptance towards pill splitting, and patients' knowledge about pill splitting. RESULTS: A total of 193 patients were recruited, and 101 returned for the follow-up visit. The percentage of split tablets falling within the assay limits increased from 39.13% to 47.82% (P=0.523) in group A and from 48.94% to 51.06% (P=1.000) in group B. The changes did not reach statistical significance. As for clinical outcomes, the mean triglyceride level decreased from 1.62±1.05 to 1.36±0.80 (P=0.049), whereas the mean heart rate increased significantly from 73.97±11.01 to 77.92±12.72 (P=0.026). Changes in other parameters were not significant. CONCLUSION: This study highlights the high variability of drug content after pill splitting. Pills with dosages that do not require splitting would be preferable, considering patients' preference. Patients should be educated to use pill cutters properly if pill splitting is unavoidable.

OBJECTIVE: Neuropathic pain (NP) is one of the most intractable complications of spinal cord injury (SCI). This study aims to explore the role of long non-coding RNA (lncRNA) SNHG1 in influencing SCI-induced NP. MATERIALS AND METHODS: After establishment of the spinal nerve ligation (SNL) model in rats, spinal tissues were extracted. SNHG1 level in rat spinal tissues was determined by quantitative real-time polymerase chain reaction (qRT-PCR). The role of SNHG1 in the development of NP was explored by assessing paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) in model rats. The interaction between SNHG1 and CDK4 was explored by Luciferase assay and RIP (RNA-Binding Protein Immunoprecipitation). Enzyme-linked immunosorbent assay (ELISA) and qRT-PCR were conducted to determine inflammatory factor levels in rat spinal tissues. RESULTS: SNHG1 was upregulated in rats undergoing SNL. Knockdown of SNHG1 alleviated the development of NP and overexpression of SNHG1 was capable of inducing NP symptoms in uninjured rats. SNHG1 induced NP by directly regulating CDK4 level. CONCLUSIONS: SNHG1 is a novel target in the treatment of NP associated with neuroinflammation.

OBJECTIVE: Cerebral ischemia/reperfusion (CIR) frequently causes serious disabilities and correlates with certain neurological processes. Some studies have shown that microRNAs (miRNAs) exert a neuroprotective effect by modulating the inflammatory process in CIR. However, the biofunction and the mechanism of miR-130b in CIR need to be fully elucidated. MATERIALS AND METHODS: An oxygen-glucose deprivation/reperfusion (OGD/R) model was constructed using SH-SY5Y cell line to analyze the function of miR-130b in CIR. Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to examine the expression levels of miR-130b and IRF1. Western blot was performed to detect the protein levels of IRF1, Bax, and Bcl-2. Cell viability was determined using MTT (3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays. Dual-Luciferase reporter assay was conducted to confirm the target gene of miR-130b. RESULTS: In this study, we found that miR-130b level was prominently decreased after treatment with OGD/R. Through gain and loss assays, we concluded that miR-130b restoration promoted cell proliferation and inhibited cell apoptosis in OGD/R-treated cells. Moreover, we also identified IRF1 as an important target of miR-130b. Additionally, IRF1 knockdown remarkably abrogated the protection mediated by miR-130b against the injuries in OGD/R-treated cells. CONCLUSIONS: Taken together, our results suggested that miR-130b facilitated cell viability and suppressed cell apoptosis of CIR via negatively regulating of IRF1.
