BackgroundPatients demonstrating depressive disorder with psychotic symptoms often have increased risk of death and poor prognosis. A large amount of research has explored the factors influencing psychotic symptoms in adult patients with depressive disorder， but few has focused on adolescent patients. ObjectiveTo explore the influencing factors of psychotic symptoms in adolescent patients with depressive disorder， so as to provide references for early screening and intervention in clinic. MethodsA total of 96 adolescent patients who met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） for depressive disorder and were seen in the psychiatry departments of Chaohu Hospital of Anhui Medical University and The Fourth People's Hospital of Hefei from September 2022 to January 2023 were included. Another 56 healthy individuals from the health examination center of Chaohu Hospital of Anhui Medical University were concurrently recruited as control group. Patients were assigned into psychotic group （n=32） and non-psychotic group （n=64） according to the presence or absence of psychotic symptoms. Hamilton Depression Scale-24 item （HAMD-24）， Positive and Negative Syndrome Scale （PANSS）， Positive and Negative Suicide Ideation （PANSI） and Childhood Trauma Questionnaire-Short Form （CTQ-SF） were used for evaluation. Plasma brain-derived neurotrophic factor （BDNF） concentration was obtained using Meso Scale Discovery electrochemiluminescence assay. Pearson and Spearman correlation analysis were adopted to determine the correlation of PANSS positive symptom subscale score with plasma BDNF concentration and clinical characteristics of adolescent depression patients with psychotic symptoms. Binary Logistic regression analysis was used to identify the factors influencing the presence of psychotic symptoms in adolescent patients with depressive disorder， and multiple linear regression analysis was utilized to screen the factors affecting the severity of psychotic symptoms. ResultsThe plasma BDNF concentration of adolescent patients with depressive disorder was lower than that of control group （t=-3.080， P<0.01）.The plasma BDNF concentration of psychotic group was lower than that of non-psychotic group （t=2.418， P<0.05）， while the body mass index （BMI） PANSI scores， CTQ-SF scores and HAMD-24 total scores were all higher than those of non-psychotic group （t=-2.024， -2.530， -2.187， -4.977， P<0.05 or 0.01）. Correlation analysis showed that PANSS positive symptom subscale scores were negatively correlated with anxiety/somatization factor score and weight factor score in HAMD-24 of psychotic group （r=-0.438， -0.498， P<0.05 or 0.01）. Binary Logistic regression showed that BMI， plasma BDNF concentration， HAMD-24 total scores and cognitive dysfunction factor score were the influencing factors of psychotic symptoms in adolescent patients with depressive disorder. Multiple linear regression analysis demonstrated that weight factor scores （β=-0.349， P<0.05） and anxiety/somatization factor score （β=-0.433， P<0.05） in HAMD-24 were the factors influencing the severity of psychotic symptoms. ConclusionHigh BMI， low plasma BDNF concentration， severe depressive symptoms and cognitive dysfunction may be the risk factors of psychotic symptoms in adolescent patients with depressive disorder， furthermore， BMI and anxiety symptoms are found to be associated with the severity of psychotic symptoms. ［Funded by Scientific Research Fund Project of Anhui Institute of Translational Medicine （number， 2022zhyx-B01）； Central Finance Supported Provincial Key Clinical Specialty Construction Project of Anhui Province in 2019］

Objective This research aims to investigate the impact of Orff music therapy on long-term schizophrenic patients in hospitals.Methods The study was a randomized,single-blind controlled trial conducted from April,2023 to September,2023.From April to September 2023,sixty-eight individuals diagnosed with persistent schizophrenia were enrolled and evenly distributed into a pair of cohorts:a treatment group of thirty-four people receiving the intervention,and an equal number forming the control group for comparative purposes.Individuals enrolled in the experimental arm of the study were administered Orff-music therapy alongside routine rehabilitation treatment across a span of two months.For a period of 8 weeks,the control group was given only standard rehabilitation treatment,whereas the research group underwent Orff-music therapy in addition to the standard rehabilitation treatment.Results Before treatment,there were no significant differences in the positive and negative symptoms scale(PANSS),the inpatient psychosis rehabilitation observe scale(IPROS)and the personal and social performance scale(psp)between two groups.After intervention,the PANSS showed that the changes were better in the study group than in the control group in 3 indicators:negative symptoms(-3.20±4.13 vs.-0.17±2.43,P<0.001),general symptoms(-2.79±3.83 vs.-0.17±2.99,P=0.003)and the total scores(-5.88±6.36 vs.0.00±4.08,P<0.001),but not in positive symptoms(P>0.05).The IPROS showed that the performances of patients in the study group were better than the control group in terms of participation in work therapy(-0.82±2.08 vs.0.23±2.10,P=0.041),socialization(-0.59±1.94 vs.0.53±1.69,P=0.014)and ability to live(-0.94±2.50 vs.0.15±1.48,P=0.033),the changes in scores before and after the intervention were significantly different when compared to the control group.The PSP showed that the changes in scores before and after the treatment of the study group was better than the control group in terms of social activity[0(-1,0)vs.0(0,0),P=0.011],and self-care[0(-1,0)vs.0(-0.25,0),P=0.012]were better than the control group.Conclusion For long-term hospitalized patients with chronic schizophrenia.Orff-music therapy can be a powerful tool for alleviating mental issues,fostering social functioning,and enhancing rehabilitation results.

Objective To investigate the inhibitory effect and molecular mechanism of Huaier granule on the growth of sorafenib resistant hepatocellular carcinoma (HCC) cells. Methods The gradient concentration of Huaier granule was used to treat HCC cells, and the effect of Huaier granule on the proliferation, migration and invasion of sorafenib resistant HCC cells was analyzed. Bioinformatics methods were used to analyze the possible interaction between microRNA-31-5p (miR-31-5p) and sprouty-related proteins with an EVH1 domain 1 (SPRED1). The expression levels of miR-31-5p and SPRED1 in HCC cells were detected by real time fluorescence quantitative polymerase chain reaction (qRT-PCR); cell viability, proliferation, migration, invasion and apoptosis were detected by CCK-8, colony formation, scratch healing, Transwell and flow cytometry; RNA immunoprecipitation (RIP) assay and dual luciferase assay were used to verify the binding relationship between miR-31-5p and SPRED1. Results Huaier granule could significantly inhibit the proliferation, migration and invasion of sorafenib resistant HCC cells, and induce apoptosis. Bioinformatics analysis showed that miR-31-5p was highly expressed in HCC, and Huaier granule was able to down-regulate the expression of miR-31-5p, inhibit the proliferation and metastasis of sorafenib resistant HCC cells, and induce apoptosis; miR-31-5p showed a targeted inhibition effect on the expression of SPRED1. SPRED1 was down-regulated in HCC, and overexpression of SPRED1 was able to reverse the promoting effect of overexpression of miR-31-5p on proliferation and metastasis of sorafenib resistant HCC. Conclusion Huaier granule can inhibit sorafenib resistant HCC metastasis through the miR-31-5p/SPRED1 axis, indicating that Huaier granule has the potential to be used as a novel drug for HCC treatment.

Background: Evidence has revealed the involvement of microRNAs (miRNAs) in modulating osteogenic differentiation, implying the promise of miRNA-based therapies for treating osteoporosis. This study investigated whether miR-181a-5p influences osteogenic differentiation and bone formation and aimed to establish the mechanisms in depth. Methods: Clinical serum samples were obtained from osteoporosis patients, and MC3T3-E1 cells were treated with osteogenic induction medium (OIM) to induce osteogenic differentiation. miR-181a-5p-, Runt-related transcription factor 1 (Runx1)-, and/or allograft inflammatory factor-1 (AIF-1)-associated oligonucleotides or vectors were transfected into MC3T3-E1 cells to explore their function in relation to the number of calcified nodules, alkaline phosphatase (ALP) staining and activity, expression levels of osteogenesis-related proteins, and apoptosis. Luciferase activity, RNA immunoprecipitation, and chromatin immunoprecipitation assays were employed to validate the binding relationship between miR-181a-5p and Runx1, and the transcriptional regulatory relationship between Runx1 and AIF-1. Ovariectomy (OVX)-induced mice were injected with a miR-181a-5p antagonist for in vivo verification. Results: miR-181a-5p was highly expressed in the serum of osteoporosis patients. OIM treatment decreased miR-181a-5p and AIF-1 expression, but promoted Runx1 expression in MC3T-E1 cells. Meanwhile, upregulated miR-181a-5p suppressed OIM-induced increases in calcified nodules, ALP content, and osteogenesis-related protein expression. Mechanically, miR-181a-5p targeted Runx1, which acted as a transcription factor to negatively modulate AIF-1 expression. Downregulated Runx1 suppressed the miR-181a-5p inhibitor-mediated promotion of osteogenic differentiation, and downregulated AIF-1 reversed the miR-181a-5p mimic-induced inhibition of osteogenic differentiation. Tail vein injection of a miR-181a-5p antagonist induced bone formation in OVX-induced osteoporotic mice. Conclusion In conclusion, miR-181a-5p affects osteogenic differentiation and bone formation partially via the modulation of the Runx1/AIF-1 axis.

Objective:To compare the efficacy of ultrasound combined with endoscopy and ultrasound combined with X-ray guided percutaneous nephrolithotomy(PCNL) in the treatment of complex renal calculi.Methods:The clinical data of 119 patients with complex kidney stones treated by ultrasound combined with endoscopy or ultrasound combined with X-ray guided PCNL in the Second Affiliated Hospital of Anhui Medical University from March 2019 to February 2022 were analyzed retrospectively. According to different guidance methods, they were divided into ultrasound combined with endoscopic guidance group and ultrasound combined with X-ray guidance group.There was no significant difference in age [(53.9±14.2) years vs. (55.6±13.5) years], gender (male/female: 38/21 vs. 30/30), body mass index [(25.0±3.7) kg/m 2 vs. (24.8±3.8)kg/m 2], stone location (left/right: 34/25 vs. 31/29), maximum diameter of renal stones [(31.9±8.3)mm vs. (33.9±13.5)mm], kidney stones maximum cross-sectional area [(601.5±242.5)mm 2 vs. (632.6±278.9)mm 2], number of renal calices involved (3.5±0.9 vs. 3.6±1.3), S. T.O.N.E. scores (9.4±1.0 vs. 9.7±1.4), Guy's grade(Ⅲ/Ⅳ: 45/14 vs. 41/19), preoperative hemoglobin [(125.2±21.5)g/L vs. (125.6±18.4)g/L], serum creatinine[(89.1±33.8) μmol/L vs. (81.9±27.1) μmol/L], urinary tract infection (43/59 vs. 47/60)and positive urinary bacterial culture (12/59 vs.11/60) between the two groups(all P>0.05). The patients in the ultrasound combined with endoscopic guidance group were placed in the modified prone split-leg position. Flexible ureteroscope retrograde into the renal pelvis, combined with ultrasound to determine the best puncture calices. The channels were established and stones were removed under the guidance of ultrasound and endoscopy. In the ultrasound combined with X-ray guidance group, the F5 ureteral catheter was placed retrogradely into the operative side ureter under the lithotomy position. Then the patient changed to prone position and the target calices were punctured under the guidance of ultrasound and X-ray. Through anterograde or retrograde injection of contrast medium, the puncture position was determined to enter in the center of the calicean dome, and the channel establishment process and stone removal are monitored. The operative results and postoperative data were recorded. Results:The average operation time in the ultrasound combined with endoscopic guidance group was significantly shorter than that in the ultrasound combined with X-ray guidance group [(90.2 ± 34.5) min vs. (129.4 ± 43.0) min, P < 0.001]. There was no significant difference in the success rates of initial channel establishment [94.0% (63/67) vs. 87.7% (107/122), P = 0.167], the time of single channel establishment [(7.7 ± 1.9) min vs. (7.7 ± 1.4) min, P =0.765], serum creatinine on the first day after operation[ (89.3±33.6) μmol/L vs. (82.9±27.0) μmol/L, P=0.257] and postoperative hospital stay[(5.3±1.6) d vs.(5.4±1.7) d, P=0.883]. In contrast, patients in ultrasound combined with X-ray guidance group had higher stone free rate [93.3% (56/60) vs. 81.4% (48/59), P=0.049] and lower reoperation rate [3.3% (2/60) vs. 15.3% (9/59), P=0.025]. The mean hemoglobin decrease value of ultrasound combined with endoscopic guidance group was significantly lower than ultrasound combined with X-ray guidance group on the first day after operation [(8.7±6.3) g/L vs. (16.8±6.9) g/L, P<0.001]. The complication rate of ultrasound combined with endoscopic guidance group was significantly lower than that of ultrasound combined with X-ray guidance group [5.1% (3/59) vs. 16.7% (10/60), P = 0.043]. Conclusions:Ultrasound combined with endoscopic guidance PCNL does not need to change body position during operation and has fewer puncture channels, thus saving operation time and reducing complications. It is more suitable for patients with isolated kidney or easy bleeding. Ultrasound combined with X-ray guidance is conducive to the establishment of multi-channel, the stone clearance rate is high and the reoperation rate is low, which is suitable for patients with good health and more renal calices involved with stones.

Objective:To discuss the feasibility and clinical efficacy of laparoscopic ureteroplasty with buccal mucosa graft for ureteral stricture.Methods:The clinical data of 10 patients with ureteral stricture admitted to the Second Affiliated Hospital of Anhui Medical University from July 2018 to November 2019 were retrospectively analyzed, including 7 males, 3 females, 5 cases on each side, with an average age of (47.9±7.8)years. All patients had a history of operation related to ureteral calculi. The median value of preoperative serum creatinine was 71(68~610)μmol/L. The status of hydronephrosis and ureteral stricture was evaluated by ultrasonography, CTU and ureteral retrograde angiography.The separation of the renal pelvis on the affected side was (3.1±0.7)cm.There were 7 cases of upper segment stenosis, 2 cases of middle segment stenosis, and 1 case of multiple stenosis. The length of ureteral stenosis was (3.2±0.7)cm. Laparoscopic buccal mucosa ureteroplasty was performed in all 10 cases under general anesthesia. After the stricture ureter segment was separated during the operation, the ureteral stenosis segment was longitudinally cut. According to the stenosis, the buccal mucosa with a length of 3.0-4.5 cm and a width of 1.0-1.5 cm was cut. Buccal mucosa grafts were harvested and placed in the ureter as an anterior onlay with omental wrapping.Results:Ureteral repair was performed laparoscopically in all cases, with no conversion to open and no serious complications. The operative time was (199.2±27.4)min, the blood loss was (101.5±54.7)ml, the median postoperative indwelling time of the drainage tube was 4.5(3.0-7.0)d, and the postoperative hospital stay was (7.9±1.9)days. The patients had clear pronunciation and barrier-free eating one week after the operation.The double J tube was removed one to two months after surgery. The patients were followed up for (11.3±4.2)months after the operation. Follow-up patients underwent imaging and other examinations, which showed significant improvement in hydronephrosis on the affected side, and the median value of renal pelvis separation on the affected side was 1.8(0-2.2)cm. The median value of serum creatinine was 82(66~235)μmol/L. The serum creatinine in 2 patients with renal insufficiency decreased significantly after operation.Conclusions:Laparoscopic buccal mucosa graft ureteroplasty could be a safe and feasible option for the treatment of ureteral stricture with less trauma and rapid recovery. The results of the initial experience are encouraging.

Objective:To explore the effects of laser irradiation parameters (irradiation frequency and single duration) on tear secretion, lens and retina.Methods:Thirty-six healthy guinea pigs were randomly divided into 6 groups with random number table method according to different frequency and single exposure duration of laser to the eye, namely, high frequency short time (HFST) group, high frequency long time (HFLT) group, medium frequency short time (MFST) group, medium frequency long time (MFLT) group, low frequency short time (LFST) group and low frequency long time (LFLT) group, 6 for each group.The right eyes were irradiated with 500 lx laser as experimental eyes, and the left eyes of the guinea pigs served as the control eyes.The high, medium and low irradiation frequencies were defined as 15 times, 10 times and 5 times, respectively, and the short and long period was defined as 30 seconds and 60 seconds each time, respectively.The right eyes were irradiated based on the grouping at a 10-minute interval.The tear secretion was detected by SchirmerⅠtest; lens opacity was assessed under the slit-lamp microscope; fundus photography was performed to evaluate the general morphology of retina; retinal function was evaluated by electroretinogram (ERG) record and the thickness of retinal outer nuclear layer was measured by histopathology examination.This study protocol was approved by the Medical Ethics Committee of Air Force Military Medical University (No.20181203), and the use and care of the experimental animals complied with the ARVO statement.Results:The tear secretion was 8.00(7.37, 9.00), 8.75(8.25, 9.00), 8.50(7.75, 9.50), 9.00(8.50, 9.50), 8.00(7.37, 8.75) and 8.25(7.75, 8.75) mm/5 min in the HFST group, HFLT group, MFST group, MFLT group, LFST group and LFLT group, respectively, without significant difference among the groups(χ 2=5.502, P=0.240); after laser irradiation, there were no statistically significant differences in tear secretion between the control eyes and laser-irradiated eyes in all the groups (all at P>0.05). The lenses were clear and the fundus was normal through the experimental duration in all the groups.The amplitude of ERG a-wave was significantly reduced in the HFST group in comparison with the LFST group (P<0.05), and there was no significant difference in the b-wave amplitude among the six groups (F=1.358, P=0.268). The ERG a-, b-wave amplitudes were not significantly different between the control eyes and laser-irradiated eyes in various groups (both at P>0.05). There was no significant difference in the thickness of the outer nuclear layer of retina among the HFST group, HFLT group, MFST group, MFLT group, LFST group and LFLT group (F=0.952, P=0.463). Conclusions:The 500 lx laser irradiation is safe to ocular surface and lens, but there are some injuries to retinal function, and the injury degree is related to laser irradiation frequency.

Objective:To explore the difference of brain structure between patients with early-onset depression with and without suicidal ideation and its relationship with the severity of depression.Methods:Totally 37 patients with early-onset depressive disorder with suicidal ideation and 23 patients with early-onset depressive disorder without suicidal ideation were examined by psychological assessment and magnetic resonance imaging(MRI)from 2019 to 2020.Voxel-based morphometry (VBM) technology was used to compare the differences in brain structure between the two groups of subjects, and further analyze the relationship between the gray matter volume of the different brain areas and the severity of depression. The demographic and clinical data were analyzed by SPSS 24.0 statistical software package. The comparison between the two groups was performed by double sample t-test and chi square test. SPM8 software was used for VBM statistical analysis, and double sample t test was used for image analysis and comparison between the two groups. Pearson correlation analysis was performed between the mean gray matter volume of the two groups and the scores of HAMD-17 and Beck scale for suicide ideation(BSI). Results:Compared with the group without suicide ideation, the volume of gray matter in the right middle frontal gyrus(MNI: x, y, z=28.5, 33.0, 43.5, FWE correction for mass level, P<0.05)and left angular gyrus of the suicide idea group increased(MNI: x, y, z=-37.5, -73.5, 48.0, FWE correction for mass level, P<0.05). There was no significant correlation between the gray matter volume of the right middle frontal gyrus and the HAMD-17 scale, BSI scale in patients with early-onset depression ( r=0.073, r=-0.153, both P>0.05). Conclusion:There are structural differences in the right middle frontal gyrus and left angular gyrus between patients with early-onset depression with suicidal ideation and patients with early-onset depression without suicidal ideation, and there was no significant correlation between gray matter volume and depression severity.
