SR proteins play important roles in regulating alternative pre-mRNA splicing. As a newly discovered neural and reproductive tissue specific SR protein, SRp38 regulates the alternative splicing of several genes important for neural function, such as GluR-B, Trk-C and NCAML1. It also acts as a splicing inhibitor during mitosis or stress response in order to prevent wrong splicing. The expression of SRp38 in mouse retina was investigated by Western blot and immunohistochemistry (IHC) analyses. The result shows that the expression of SRp38 proteins in mouse retina is region-specific, with extensive distribution in the outer and inner plexiform layers, inner nuclear layer and ganglion cell layer, but no expression in outer nuclear layer. Double staining of isolated retina cells with anti-SRp38 and anti-Trk-C antibodies showed that SRp38 is localized in the dendrites, somata and axon terminals of rod-bipolar cells. By transient co-transmission of over-expressed SRp38 plasmid and RT-PCR analyses, the further results showed that overexpressed SRp38 could promote the splicing of the Flip isoform of GluR-B minegene in R28 cells. The result suggests that SRp38 may play important roles in the retinal function, possibly via regulating the neural-specific alternative splicing of genes as GluR-B.

OBJECTIVETo compare the perioperative complications between Ivor-Lewis approach and McKeown approach in minimally invasive esophagectomy and gastric tube reconstruction for the treatment of middle and lower thoracic esophageal cancer.

METHODSRetrospective analysis of clinical data was performed on 288 patients with middle and lower thoracic esophageal cancer who underwent completely minimally invasive esophagectomy by one surgical team in Fujian Medical University Union Hospital from December 2010 to March 2014. Among the 288 patients, 103 patients underwent combined laparoscopic and thoracoscopic esophagectomy and intrathoracic esophagogastric anastomosis using a transoral anvil(Orvil)(Ivor-Lewis group, 2-incision) and 185 patients underwent combined laparoscopic and thoracoscopic esophagectomy and cervical anastomosis(McKeown group, 3-incision). Patients were stratified by surgical approach and perioperative outcomes were compared between the two groups.

RESULTSThere were no statistical differences between two groups in intra-operative blood loss, conversion to open, extubation time, time to resume oral intake, postoperative hospital stay, the median number of lymph nodes resected. The operation time of Ivor-Lewis group was significantly shorter than that of McKeown group [(283.4±32.0) min vs. (303.6±43.7) min, P=0.003). The hospital cost of Ivor-Lewis group was significantly higher than that of McKeown group [(76 492±18 553) yuan vs. (68 923±17 331) yuan, P<0.01]. There were no statistical differences between two groups in chylothorax, delayed gastric emptying, atrial fibrillation, postoperative bleeding, admission to ICU, short-term postoperative mortality (P>0.05). The total postoperative complication morbidity of Ivor-Lewis group was significantly lower than that of McKeown group(16.5% vs. 31.4%, P<0.01). Ivor-Lewis group had lower pulmonary complication(8.7% vs. 25.9%, P<0.01), anastomotic leakage(1.9% vs. 13.0%, P<0.01), anastomotic stricture (0% vs. 4.9%, P<0.05), recurrent laryngeal nerve injury(1.0% vs. 7.0%, P<0.05).

CONCLUSIONIvor-Lewis approach is associated with less postoperative complications, but higher cost as compared to McKeown approach in the treatment of middle and lower thoracic esophageal cancer.

Objective:To evaluate the efficacy of Sun's sequential therapy (SST) of Chinese Medicine on allergic rhinitis with lung deficiency and cold syndrome.Methods:A total of 60 AR patients with lung deficiency and cold syndrome in otolaryngology clinic of Guang'anmen Hospital, from January to July 2020, who met the inclusion criteria, were randomly divided into 2 groups according to the random number table method, with 30 patients in each group. The Traditional Chinese Medicine (TCM) group was treated with oral Yupingfeng Powder and Cang'erzi Powder and the SST group was treated with oral and nasal steaming of Yupingfeng Powder and Cang'erzi Powder. Both groups were treated for 14 days. The clinical symptoms were scored before and after treatment, and the Nasal mucosa eosinophil (EOS) count was graded by Sheldon method to evaluate the clinical efficacy.Results:Twenty five patients in the SST group and 28 in the TCM group were analyzed. The total effective rate was 88.0% (22/25) in the SST group and 89.3% (25/28) in the TCM group, and there was no significant difference between the two groups ( χ2=2.83, P=0.883). The scores of nasal obstruction, runny nose, sneeze and total score in the SST group were significantly lower than those in the TCM group ( P<0.01), and the difference of Nasal mucosa EOS grade in SST group (2.76±0.27 vs. 1.52±0.36) was significantly higher than that of the TCM group ( P=0.01). Conclusion:The SST of Chinese medicine can improve the symptoms of nasal congestion, runny nose and sneezing in AR patients with lung deficiency and cold syndrome, and reduce the distribution of Nasal mucosa EOS.

N6-methyladenosine(m6A)represents one of the most abundant modifications in eukaryotes RNA.M6A modification is catalyzed and modified by m6A methyltransferases and demethylases.The fates of m6A-modified mRNAs rely on the functions of distinct"reader"proteins that recognize them,which may affect the splicing,processing,translation or degradation of the target mRNAs.Methyltransferase-like 3(METTL3)is a catalytic core component of m6A methyltransferase compound,whose abnormal expression could lead to disordered m6A modifications and further influence the proliferation,invasion,migration and drug resistance of tumor cells.As the functions of METTL3 have been explored in depth,METTL3 inhibitors have become research hotspots.Therefore,this review focus on the different target molecules and downstream signaling pathways affected by METTL3 with the assistance of different readers in the tumorigenesis and progression of urologic tumors,and summarizes the research progress of METTL3 inhibitors,in the hope to provide insights for the prevention,diagnosis and treatment of tumors.

Recent studies have shown that targeting apoptosisˉrelated genes have potentials in the treatment of lymphoma, and the treatment of Bclˉ2 inhibitors and Bax activators combined with chemotherapy has attracted much attention. This article reviews the progress of apoptosisˉrelated genes and DLBCL.

Objective:To study the risk of refracture after osteoporotic vertebral fracture with changes in blood calcium and bone metabolism.Methods:260 patients with osteoporotic vertebral fracture treated in our hospital from Feb. 2018 to Feb. 2020 were selected for study. All patients were treated with kyphoplasty. The clinical curative effect, blood calcium, PINP, and β-CTX level changes were observed, postoperative recurrence was followed up. Clinical data of fracture patients were collected, risk factors of osteoporotic vertebral fractures in patients with postoperative recurrence of fracture were analyzed, receiver-operating characteristic curve was drawn to analyze the predictive value of blood calcium, PINP, andβ-CTX in postoperative recurrence of osteoporotic vertebral fracture.Results:The total clinical response rate was 95.77% (249/260) after treatment. After treatment, serum calcium, PINP, and β-CTX decreased with time, and the difference was significant ( P<0.05) . All patients were followed up for 6 months. There were 81 cases (31.15%) suffering postoperative fracture and 179 cases (68.85%) without fracture. According to univariate analysis, there were no statistically significant differences in age, sex, BMI, history of trauma, underlying disease, site of surgical vertebral body, segment of surgical vertebral body, correction angle of sagittal kyphosis, or amount of bone cement injection between the two groups ( P>0.05) . Long-term history of glucocorticoid use, preoperative fractured vertebra number, surgical vertebra number, blood calcium, PINP, β-CTX, fracture compression rate, vertebra height recovery rate, reinforced vertebra number, and bone cement leakage were correlated with postoperative recurrence of fracture in patients with osteoporotic vertebral fracture ( P<0.05) . Multivariate Logistic analysis showed that long-term history of glucocorticoid use, preoperative number of fractured vertebrae, surgical vertebra number, fracture compression rate, vertebral height recovery rate, enhanced vertebral body number, bone cement leakage, blood calcium, PINP, and β-CTX were all independent risk factors for postoperative recurrence of osteoporotic vertebral fracture ( P<0.05) . ROC curve results showed that AUC, 95%CI and truncation value were 0.820, 0.770-0.871 and 2.12mmol/L vs 0.915, 0.873-0.957 and 45.51 ng/mL vs 0.973, 0.957-0.988, and 463.29 for serum calcium, PINP, and β-CTX respectively in predicting the recurrence of osteoporotic vertebral fracture. Conclusion:Kyphoplasty has a significant effect on osteoporotic vertebral fracture, and it can effectively improve the serum calcium, PINP, and β-CTX, which have a certain monitoring value for postoperative recurrence of fracture.

Objective:To explore the characteristics of cerebellar metabolites of autistic children using the magnetic resonance spectrum (MRS) and analyze their correlation with clinical symptoms.Methods:An autism group ( n=14) and a control group ( n=8) both underwent bilateral MRS scans of their cerebella. The NAA, Cho and Cr absolute values were recorded along with the NAA/Cr and Cho/Cr ratios. Those values were correlated with clinical symptoms of autism (the CARS and ABC scales), as well as with age. Results:There were no significant differences between the two groups in cerebellar metabolite levels, but the autism group exhibited significantly higher Cho/Cr ratios in the right cerebellum than in the left. There was a significant positive correlation between the Cho/Cr ratio in the right cerebellum and CARS scores, and between the NAA/Cr ratio in the right cerebellum and age.Conclusions:There is metabolic abnormality in the left and right cerebellar hemispheres of autistic children. The metabolic abnormality is related to the severity of clinical symptoms. However, metabolism in the cerebellum improves gradually with age.

OBJECTIVES: To evaluate the feasibility and safety of bipolar-plasmakinetic transurethral enucleation and resection of the prostate (B-TUERP) in day surgery. METHODS: From January 2021 to August 2022, 34 patients with benign prostatic hyperplasia (BPH) underwent B-TUERP in day surgery in the First Affiliated Hospital of Anhui Medical University. Patients completed the screening and anesthesia evaluation before admission and received the standard surgery which implements "anatomical enucleation of the prostate" and "absolute bleeding control" on the same day of admission, and by the same doctor. Bladder irrigation was stopped, catheter was removed and the discharge evaluation was performed on the first day after operation. The baseline data, perioperative conditions, time of recovery, treatment outcomes, hospitalization costs, and postoperative complications were analyzed. RESULTS: All operations were successfully conducted. The average age of the patients was (62.2±7.8) years, average prostate volume was (50.2±29.3) mL. The average operation time was (36.5±19.1) min, the average hemoglobin and blood sodium were decreased by (16.2±7.1) g/L and (2.2±2.0) mmol/L, respectively. The average postoperative length of hospital stay, and total length of hospital stay were (17.7±2.2) and (20.8±2.1) h, respectively, and the average hospitalization cost was (13 558±2320) CNY. All patients were discharged on the day after surgery except for one patient who was transferred to a general ward. Three patients received indwelling catheterization after catheter removal. The 3-month follow-up results showed a substantial improvement in the International Prostate Symptom Score, quality of life score and maximum urinary flow rate (all P<0.01). Three patients experienced temporary urinary incontinence, 1 patient experienced urinary tract infection, 4 patients were diagnosed with urethral stricture and 2 patients experienced bladder neck contracture. No complications above Clavien grade Ⅱ occurred. CONCLUSIONS The preliminary results showed that B-TUERP ambulatory surgery is a safe, feasible, economical and effective treatment for appropriately selected patients with BPH.
