Objective To analyze the trend of global cellulitis disease burden from 1990 to 2019, and to provide a theoretical basis for the prevention and control of cellulitis disease. Methods The Global Burden of Disease 2021 (GBD2021) data were collected, and data on the incidence, mortality, and disability-adjusted life year (DALY) of cellulitis were analyzed for each country worldwide. The estimated annual percentage change (EAPC) and age-standardized rate (ASR) were used to estimate the trend change of cellulitis from 1990 to 2021. Results The global burden of cellulitis increased significantly in 2021, with 55.96 million cases, 28.9 million deaths and 876.1 million DALYs, respectively. Incidence and mortality rates were generally higher in males than in females. The incidence and DALYs were higher in high SDI regions, with the highest burden observed in South Asia. In contrast, East Asia exhibited the lowest burden and demonstrated a declining trend. There were significant differences between countries, with India having the highest prevalence, the United States having the highest incidence, and Bahrain having the fastest growing rate.In 2021, China had the lowest age-standardised incidence of cellulitis in the world and the fastest declining age-standardised incidence and age-standardised DALYs. Conclusion The global disease burden of cellulitis is increasing from 1990-2021, and cellulitis remains an an important global public health problem. Targeted preventive meausres should be taken in areas with different economical levels. Men, middle-aged and elderly people, and newborns are the key groups in need of attention and health education.

Objective To explore the feasibility and short-term clinical efficacy of single segment thora-columbar tuberculosis treated with one-stage posterior approach lamina-sparing decompression.Methods A total of 11 patients with single segment thoracolumbar tuberculosis who underwent one-stage posterior ap-proach preservation of vertebral plate lesion removal,bone graft fusion,and internal fixation treatment in this hospital from September 2021 to June 2022 were selected.C-reactive protein(CRP)and erythrocyte sedimen-tation rate(ESR)were monitored to evaluate tuberculosis bacteremia and activity control,visual analogue scale(VAS)score and Oswestry disability index(ODI)were followed up to evaluate the improvement of clin-ical function,and the American Spinal Injury Association(ASIA)injury scale was used to evaluate neurologi-cal function,and the correction of kyphosis was followed up.Results All 11 patients were fully followed up.The average surgical duration is(270.91±45.98)minutes,and the average surgical bleeding is(522.72± 194.11)mL.During the follow-up period,none of the 11 patients experienced tuberculosis recurrence,and all 11 patients achieved bone graft fusion.The fusion time was 6-9 months after surgery with an average of(7.36±1.12)months.Two patients with preoperative nerve damage recovered after surgery.During the fol-low-up period,11 patients did not experience any complications related to surgery.The average CRP,ESR,ODI score,and VAS score of postoperative patients decreased compared to preoperative levels,and further de-creased at 12 months after surgery;The patient's kyphosis caused by thoracolumbar tuberculosis was correc-ted,and no obvious angle loss was found at the last follow-up(P＞0.05).Conclusion One-stage posterior ap-proach lamina-sparing decompression is a safe and effective method for treating single segment thoracolumbar tuberculosis.

Infectious diarrhea is a gastrointestinal infectious disease caused by a wide range of pathogens and found throughout the world. It is one of the most important public health problems in the world and the second leading cause of death among children under five years of age. The pathogens of infectious diarrhea include viral diarrhea pathogens, bacterial diarrhea pathogens, and parasites. Viruses are the most frequent pathogens, mainly including norovirus, rotavirus, astrovirus and sapovirus. The most frequently identified organisms causing bacterial diarrhea are diarrheagenic Escherichia coli, Salmonella, Shigella, Vibrio parahaemolyticus and Campylobacter. This paper provides an overview of the epidemiological trends and changes in the pathogen spectrum of infectious diarrhea for better understanding the distribution and epidemiological features of infectious diarrhea in China, and hopes to provide reference for developing prevention and control strategies and reducing the disease burden.

Objective:To analyze the efficacy, safety and learning curve of Thulium laser enucleation of the prostate by laser controller(LC-THuLEP) anchored at six o'clock position of the bladder neck in the treatment of benign prostatic hyperplasia(BPH) with large gland.Methods:The clinical data of the 1st to 45th BPH cases with large gland(prostate volume> 80 ml) treated by a doctor with LC-THuLEP anchored at six o'clock position of bladder neck in Shanghai East Hospital from January to October 2022 were retrospectively analyzed. The patients were divided into groups A, B and C according to the order of operation time, with 15 cases in each group. There were no significant differences among the three groups( P>0.05) in age[(71.8±9.4)years old vs. (73.5±8.2) years old vs.(71.4±5.5)years old], prostate volume[88.3(84.8, 100.6)ml vs.91.5(86.1, 118.4)ml vs. 94.5(84.7, 101.8)ml], prostate specific antigen(PSA)[4.8(2.9, 8.5)ng/ml vs. 7.2(3.2, 11.2)ng/ml vs. 7.8(4.5, 12.7)ng/ml], postvoid residual volume[44.0(34.0, 67.0)ml vs. 60.0(40.0, 76.0)ml vs. 39.0(0, 59.0)ml], maximum urine flow rate(Q max)[8.4(7.6, 11.1)ml/s vs. 8.6(6.5, 10.6)ml/s vs. 10.4(7.8, 13.2)ml/s], international prostate symptom score(IPSS)[20(18, 21) vs. 20(20, 22) vs. 20(20, 25)]and quality of life(QOL)[4(4, 5) vs. 4(4, 4) vs. 4(3, 5)].The doctor had more than 100 cases of TURP surgery experience. LC-THuLEP anchored at six o'clock position of bladder neck was described as follows. The bladder neck at six o'clock position is reserved 0.5-1.0 cm as an "anchor" to fix the prostatic bladder neck when the gland was pushed directly by the laser controller, preventing the detached prostate gland from turning. Finally the bladder neck was cut off at six o'clock position, and the prostate was en-bloc removed. The effect of surgery and postoperative complications were compared. The enucleation efficiency was equal to the weight of prostate tissue removed divided by the time of enucleation. Results:The differences among the three groups in operation time [100.0(90.0, 110.0)min vs. 80.0(70.0, 90.0)min vs. 75.0(70.0, 90.0)min], enucleation time[89.0(72.0, 97.0)min vs. 67.0(64.0, 77.0)min vs. 64.0(60.0, 77.0)min] and the efficiency of enucleation [0.65(0.62, 0.68)g/min vs. 0.84(0.83, 0.94)g/min vs. 0.93(0.82, 1.00)g/min] were statistically significant( P<0.05). The operation time and enucleation time in groups B and C were significantly lower than those in group A, and the enucleation efficiency was significantly higher than that in group A( P<0.05), while there was no significant difference between group B and C. However, the difference of three groups in hemoglobin decrease [8.0(5.0, 11.0)g/L vs. 7.0(2.0, 10.0)g/L vs. 11.0(4.0, 16.0)g/L] and catheter indwelling duration[4.0(2.0, 6.0)d vs. 6.0(3.0, 7.0)d vs. 4.0(3.0, 6.0)d] were not statistically different( P>0.05). All patients were followed up for 6 months after surgery. In three groups, postoperative Q max were 23.2(21.0, 25.1)ml/s, 22.7(21.1, 26.1)ml/s and 22.9(21.5, 25.7)ml/s, IPSS were 6(5, 8), 7(6, 8) and 7(7, 8), QOL were 2(1, 2), 2(1, 2) and 2(1, 2), postvoid residual volume were 20.0(10.0, 25.0)ml, 22.0(15.0, 25.0)ml and 5.0(0, 25.0)ml, respectively, which were all significantly different from that of pre-operation( P<0.05).However, there were no statistically significant differences in the postoperative indicators among the three groups ( P>0.05). No statistical difference was found in postoperative complications among the three groups[26.7%(4/15) vs. 20.0%(3/15) vs. 20.0%(3/15), P>0.05]. Conclusions:LC-THuLEP anchored at six o'clock position of bladder neck was an effective operation in the treatment of BPH with large gland, and the learning curve could be reached after 15 cases.

Objective:To investigate the efficacy of Peritoneal interposition flap (PIF) technique in preventing postoperative pelvic lymphocele formation during laparoscopic radical prostatectomy with extended pelvic lymph node dissection (LRP+ ePLND).Methods:A retrospective analysis was conducted on clinical data of 113 patients with locally high-risk or locally advanced prostate cancer who underwent LRP+ ePLND at Shanghai East Hospital, from January 2020 to November 2023. Among them, 27 patients received PIF technique and 86 received traditional LRP+ ePLND. ePLND was carried out as the clearance of external iliac vessels, medial side of the internal iliac artery, and pararectal lymph nodes. The PIF technique was the suturing the peritoneal flap after freeing the bladder to the lateral side of the bladder, pulling the peritoneal edge that follows the bladder's free edge posteriorly to the pubis, curling it onto the lateral surface of the bladder. This could expose the lymph node clearance bed, establishing a pathway from the lymph node clearance bed to the abdominal cavity space, allowing exuded lymphatic fluid to flow into the abdominal cavity for absorption by the peritoneum. There were no statistically significant differences in age [(68.37±6.92)years vs.(70.47±5.72)years], body mass index [(25.47±2.49)kg/m 2vs.(24.46±2.80)kg/m 2], and preoperative PSA [(23.28±13.94)ng/ml vs.(24.81±13.99)ng/ml] between the PIF group and the control group ( P>0.05). Biopsy Gleason score in PIF group: 6 in 2 cases, 7 in 9 cases, 8 in 9 cases, 9-10 in 2 cases. Biopsy Gleason score in control group: 6 in 4 cases, 7 in 35 cases, 8 in 27 cases, 9-10 in 20 cases. Clinic stage in PIF group: T 2 in 18 cases, T 3 in 6 cases, T 4 in 3 cases. Clinic stage in control group: T 2 in 51cases, T 3 in 27 cases, T 4 in 8 cases. The preoperative Gleason scores and TNM staging comparisons between the PIF group and the control group showed no statistically significant differences ( P>0.05). Surgical duration, intraoperative blood loss, lymph node positivity rate, incidence of postoperative lymphocele, and recovery of urinary control were compared between the two groups. Results:All surgeries were completed successfully without intraoperative complications in both groups. There were no statistically significant differences between the PIF group and the control group in terms of surgical duration [(202.96±24.15)min vs.(201.1±29.85)min], intraoperative blood loss [(85.56±32.27)ml vs.(90.7±49.25)ml], and lymph node positivity rate [(4 in PIF group, 14.8%)vs.(25 in control group, 29.1%)]( P>0.05). Urinary catheters were retained for 10-14 days postoperatively. Following catheter removal, there were no statistically significant differences in urinary control rates at 1 month [51.85%(14/27)vs. 48.83%(42/86)]and 2 months[74.07%(20/27) vs. 72.09%(62/86)] between the PIF group and the control group ( P>0.05). At the 2 to 6-month follow-up CT scan, none of the 27 patients in the PIF group developed pelvic lymphocele, whereas 9 patients in the control group did (6 cases bilateral, 3 cases unilateral), showing a statistically significant difference between the two groups ( P=0.002). Postoperatively, 3 patients in the control group experienced symptoms, with 1 case of lymphocele infection causing fever 1 month after surgery. Lymphocysts were found in 2 patients with ipsilateral lower extremity swelling 2 weeks after surgery. Conclusions:The application of PIF technique during laparoscopic radical prostatectomy with extended pelvic lymph node dissection via the abdominal approach could be safe and feasible. It may prevent postoperative pelvic lymphocele formation.

Depression is a common mental illness in adolescents, and some patients do not respond well after medication, which may be partly related to vitamin D deficiency and insufficient calcium intake. This paper reports a 15-year-old patient with depression, whose condition was still unstable and the effect was not good despite routine use of antidepressant drugs and psychological intervention. After adequate supplementation of vitamin D and calcium, the patient's depression improved significantly, and the follow-up for 4 months, the condition was stable and did not recur.

Objective:To explore the relationship between the levels of serum P-glycoprotein（P-gp）and claudin-5 with epilepsy and cognitive impairment in children.Methods:A total of 120 children with epilepsy admitted to Xingtai People's Hospital from June 2020 to June 2022 were retrospectively selected as the epilepsy group，and divided into the general tonic-clonic seizure group（ n=44）and the focal seizure group（ n=76）according to the type of epilepsy，and also divided into the cognitive normal group（ n=88）and the cognitive impairment group（ n=32）according to the cognitive function of the children. Another 100 healthy children in the hospital were selected as the control group. Serum P-gp and claudin-5 levels were detected by enzyme-linked immunosorbent assay and compared between the two groups. Pearson correlation was used to analyze the relationship between serum P-gp，claudin-5 levels and epilepsy condition in children. Receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of serum P-gp and claudin-5 for cognitive impairment in children with epilepsy. Results:The serum P-gp level in the epilepsy group was higher than that in the control group[(3.11±0.34) ng/L vs. (1.33±0.17) ng/L]，and the serum claudin-5 level was lower than that in the control group[(0.66±0.12) ng/mL vs. (1.66±0.28) ng/mL] , and the differences were statistically significant (all P<0.05). The serum P-gp level in the generalized tonic-clonic seizure group was higher than that in the focal seizure group [(5.62±1.02) ng/mL vs. (2.55±0.28) ng/mL]，and the serum claudin-5 level was lower than that in the focal seizure group[(0.40±0.05) ng/mL vs. (1.10±0. 25) ng/mL] , and the differences were all statistically significant (all P<0.05). Pearson correlation analysis showed that serum P-gp was positively correlated with negatively correlated with national hospital seizure severity scale(NHS3) score in pediatric epilepsy（ r=0.447， P<0.05），and serum claudin-5 was NHS3 score in pediatric epilepsy（ r=-0.485， P<0.05）. The serum P-gp level in the cognitive impairment group was higher than that in the cognitive normal group [(5.87±1.05) ng/L vs. (2.44±0.26) ng/L]，and the serum claudin-5 level was lower than that in the cognitive normal group [(0.32±0.03) ng/mL vs. (0.86±0.08) ng/mL], and the differences were all statistically significant (all P<0.05). ROC curve analysis showed that the area under the curve（AUC）of serum P-gp for evaluating cognitive impairment in children with epilepsy was 0.831（95% CI 0.781-0.881），the AUC of serum claudin-5 for evaluating cognitive impairment was 0.854（95% CI 0.804-0.904），and the AUC of the combination was 0.905（95% CI 0.855-0.955）. Conclusion:Serum P-gp level is increased and claudin-5 level is decreased in children with epilepsy，and both levels are closely associated with the disease condition and cognitive impairment，with the combination of the two indexes more effective than either indicator in diagnosing cognitive impairment in pediatric epilepsy.

Objective:To investigate the potential mechanism of miR-1298-5p in non-small cell lung cancer(NSCLC)to regu-late the MSH2 gene and its effect on the biological behavior of tumor cells and the tumor immune microenvironment.Methods:Bioin-formatics was used to identify the key genes and miRNA involved in NSCLC.Cell proliferation was detected by CCK-8 assay,and cell invasion and migration were detected by Transwell assay.Levels of inflammatory factors were detected by ELISA assay.Western blot was used to measure the expression of MSH2 in cells,and fluorescence quantitative polymerase chain reaction(RT-qPCR)was used to detect the expressions of miR-1298-5p and MSH2 gene in NSCLC cells.Dual luciferase reporter gene assay was performed to verify the targeting relationship between miR-1298-5p and MSH2.Spearman correlation analysis was performed to correlate miR-1298-5p with immune cells and immune factors in the tumor immune microenvironment.Results:The level of miR-1298-5p was down-regulated in NSCLC cells compared with normal lung tissue cells.miR-1298-5p overexpression inhibited the proliferation,migration and inva-sion of NSCLC cells.MSH2 was confirmed to be a target gene of miR-1298-5p using luciferase reporter gene assay.Furthermore,down-regulation of miR-1298-5p in NSCLC cells could be reversed by silencing MSH2.miR-1298-5p expression levels were negatively corre-lated with the levels of Treg,IL-10,and TGF-β,and positively correlated with the levels of CD3+T,CD4+T,CD8+T,NK cells,IL-2,and IFN-γ.Conclusion:miR-1298-5p negatively regulates MSH2 to inhibit the proliferation,invasion and migration of NSCLC cells and improve the tumor immune microenvironment.

Objective:To investigate the protective effect of quercetin (QR) on acute liver injury induced by diquat (DQ) poisoning in mice and its mechanism.Methods:Eighty healthy male C57BL/6 mice with SPF grade were randomly divided into control group, DQ model group, QR treatment group, and QR control group, with 20 mice in each group. The DQ poisoning model was established by a one-time intraperitoneal injection of DQ solution (40 mg/kg); the control and QR control groups received equivalent amounts of distilled water through intraperitoneal injection. Four hours after modeling, the QR treatment group and the QR control group received 0.5 mL QR solution (50 mg/kg) through gavage. Meanwhile, an equivalent amount of distilled water was given orally to the control group and the DQ model group. The treatments above were administered once daily for seven consecutive days. Afterwards, the mice were anesthetized, blood and liver tissues were collected for following tests: changes in the structure of mice liver tissue were observed using transmission electron microscopy; the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected using enzyme linked immunosorbent assay (ELISA); the levels of glutathione (GSH), superoxide dismutase (SOD), and malondialdehyde (MDA) in liver tissues were measured using the water-soluble tetrazolium-1 (WST-1) method, the thiobarbituric acid (TBA) method, and enzymatic methods, respectively; the protein expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), Kelch-like ECH-associated protein 1 (Keap1), and activated caspase-9 in liver tissues were detected using Western blotting.Results:Severe mitochondrial damage was observed in the liver tissues of mice in the DQ model group using transmission electron microscopy, yet mitochondrial damage in the QR treatment group showed significant alleviation. Compared to the control group, the DQ model group had significantly increased levels of MDA in liver tissue, serum AST, and ALT, yet had significantly decreased levels of GSH and SOD in liver tissue. In comparison to the DQ model group, the QR treatment group exhibited significant reductions in serum levels of ALT and AST, as well as MDA levels in liver tissue [ALT (U/L): 52.60±6.44 vs. 95.70±8.00, AST (U/L): 170.45±19.33 vs. 251.10±13.09, MDA (nmol/mg): 12.63±3.41 vs. 18.04±3.72], and notable increases in GSH and SOD levels in liver tissue [GSH (μmol/mg): 39.49±6.33 vs. 20.26±3.96, SOD (U/mg): 121.40±11.75 vs. 81.67±10.01], all the differences were statistically significant (all P < 0.01). Western blotting results indicated that the protein expressions of Nrf2 and HO-1 in liver tissues of the DQ model group were significantly decreased compared to the control group. On the other hand, the protein expressions of Keap1 and activated caspase-9 were conspicuously higher when compared to the control group. In comparison to the DQ model group, the QR treatment group showed a significant increase in the protein expressions of Nrf2 and HO-1 in liver tissues (Nrf2/β-actin: 1.17±0.08 vs. 0.92±0.45, HO-1/β-actin: 1.53±0.17 vs. 0.84±0.09). By contrast, there was a notable decrease in the protein expressions of Keap1 and activated caspase-9 (Keap1/β-actin: 0.48±0.06 vs. 1.22±0.09, activated caspase-9/β-actin: 1.17±0.12 vs. 1.59±0.30), the differences were statistically significant (all P < 0.01). Conclusion:QR may reduce acute liver injury induced by DQ poisoning in mice via activating Keap1/Nrf2 signaling pathway.
