Objective:To evaluate the effect of preemptive analgesia with ibuprofen on postoperative pain following single posterior tooth implantation, aiming to provide a clinical reference for its application.Methods:A multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted. A total of 82 participants were included in the trial, meeting the eligibility criteria from April 2022 to April 2024 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), Beijing Chao-Yang Hospital, Capital Medical University (20 cases). Participants were randomly assigned in a 1∶1 ratio to either the ibuprofen group or the control group, with each group comprising 41 individuals. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups received the same postoperative analgesic regimen for 3 days. Pain scores were assessed using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h postoperatively, and the additional use of analgesic medication was recorded from days 4 to 6 postoperatively.Results:A total of 82 participants were initially enrolled in the study, with 7 dropouts (4 from the control group and 3 from the ibuprofen group), resulting in 75 participants (37 in the control group and 38 in the ibuprofen group) completing the trial. There were no reports of adverse events such as nausea or vomiting among the participants. The ibuprofen group exhibited significantly lower pain scores at 4 h, 6 h and 8 h [1.0 (0.0, 2.0), 1.0 (0.0, 2.0), 1.5 (0.0, 3.0) ] postoperatively compared to the control group 4 h, 6 h and 8 h [2.0 (1.0, 3.0), 3.0 (1.5, 4.0), 2.0 (1.0, 4.0)] ( Z=-1.99, P=0.047; Z=-3.01, P=0.003; Z=-2.10, P=0.036). The proportions of patients requiring additional analgesic medication between days 4 and 6 post-surgery were 18.4% (7/38) in the ibuprofen group and 27.0% (10/37) in the control group, with no significant difference (χ 2=0.79, P=0.373). The median additional medication usage postoperatively was [0.0 (0.0, 0.0) pills] in the ibuprofen group and [0.0 (0.0, 1.0) pills] in the control group, with no significant difference ( Z=-0.78, P=0.439). Conclusions:Preemptive analgesia with ibuprofen effectively reduces postoperative pain following tooth implantation, representing a safe and effective perioperative pain management strategy.

Objective: To investigate the characteristics and comprehensive treatment of infected wounds in patients with iatrogenic Cushing's syndrome. Methods: A retrospective observational study was conducted. From May 2012 to December 2021, the data of 19 patients with iatrogenic Cushing's syndrome discharged from the Department of Burns and Plastic Surgery of the First Affiliated Hospital of Guangxi Medical University were collected, including 8 males and 11 females, aged 28-71 (56±11) years, with 12 cases of infected acute wounds and 7 cases of infected chronic wounds. The lesions were located in the limbs, perianal, and sacrococcygeal regions, with original infection ranging from 9 cm×5 cm to 85 cm×45 cm. After admission, the patients were performed with multidisciplinary assisted diagnosis and treatment, and the wounds were treated with debridement and vacuum sealing drainage, according to the size, severity of infection, suture tension, and bone and tendon tissue exposure of wounds, direct suture or autologous skin and/or artificial dermis and/or autologous tissue flap transplantation was selected for wound repair. The levels of cortisol and adrenocorticotropic hormone (ACTH) of patients at 8:00, 16:00, and 24:00 within 24 h after admission were counted. After admission, the number of operations, wound repair methods, and wound and skin/flap donor site healing of patients were recorded. During follow-up, the wounds were observed for recurrent infection. Results: The cortisol levels of 16 patients at 8:00, 16:00, and 24:00 within 24 h after admission were (130±54), (80±16), and (109±39) nmol/L, respectively, and ACTH levels were (7.2±2.8), (4.1±1.8), and (6.0±3.0) pg/mL, respectively; and the other 3 patients had no such statistical results. After admission, the number of surgical operation for patients was 3.4±0.9. The following methods were used for wound repair, including direct suturing in 4 cases and autologous skin and/or artificial dermis grafting in 9 cases, of which 2 cases underwent stage Ⅱ autologous skin grafting after artificial dermis grafting in stage Ⅰ, and 6 cases had pedicled retrograde island flap+autologous skin grafting. The wound healing was observed, showing that all directly sutured wounds healed well; the wounds in 6 cases of autologous skin and/or artificial dermis grafting healed well, and the wounds in 3 cases also healed well after the secondary skin grafting; the flaps in 4 cases survived well with the wounds in 2 cases with distal perforators flap arteries circumfluence obstacle of posterior leg healed after stage Ⅱ debridement and autologous skin grafting. The healing status of skin/flap donor sites was followed showing that the donor sites of medium-thickness skin grafts in the thigh of 4 cases were well healed after transplanted with autologous split-thickness grafts from scalp; the donor sites of medium-thickness skin grafts in 3 cases did not undergo split-thickness skin grafting, of which 2 cases had poor healing but healed well after secondary skin grafting 2 weeks after surgery; the donor sites of split-thickness skin grafts in the head of 2 patients healed well; and all donor sites of flaps healed well after autologous skin grafting. During follow-up of more than half a year, 3 gout patients were hospitalized again for surgical treatment due to gout stone rupture, 4 patients were hospitalized again for surgical treatment due to infection, and no recurrent infection was found in the rest of patients. Conclusions: The infected wounds in patients with iatrogenic Cushing's syndrome have poor ability to regenerate and are prone to repeated infection. Local wound treatment together with multidisciplinary comprehensive treatment should be performed to control infection and close wounds in a timely manner, so as to maximize the benefits of patients.

Objective: To report the clinical features and genetic variations of monogenic lupus caused by DNASE1L3 deficiency and to introduce preliminary experience on diagnosis and treatment for this disease. Methods: Clinical data of 3 children from the same pedigree were collected who were diagnosed with DNASE1L3 defect-associated monogenic lupus in August 2020 by Department of Pediatrics, Peking Union Medical College Hospital referred from Department of Pediatrics, Boai Hospital of Zhongshan. DNA was extracted from the peripheral blood of the patients and their parients to perform genetic analysis and confirmation. Six interferon-stimulated genes were relatively quantified to examine the activation of the type I interferon signaling. "DNASE1L3" "systemic lupus erythematosus" and "SLE" were searched in PubMed, Wangfang Data, CNKI databases for related reports from database established date to June 2022. Spectrum of genetic variations and clinical phenotypes were analyzed in combination with this pedigree. Results: Case 1, a 14-year-old girl with edema, hematuria, and heavy proteinuria, presented with membranous nephropathy. Case 2, the 12-year-old younger brother of case 1 with hematologic, cardiac, pulmonary, renal involvement, positive antinuclear antibody, positive anti-double-stranded DNA antibody and low complement C3, manifested with systemic lupus erythematosus. Case 3, the 8-year-old younger sister of case 1 with hematologic, cardiac, pulmonary and renal involvement, positive antinuclear antibody, positive anti-double-stranded DNA antibody, and low complement C3 and C4, manifested with systemic lupus erythematosus. Genetic testing revealed that all 3 patients carried homozygous deletions in exons 3 and 4 on DNASE1L3 gene. Interferon scores were elevated in case 1, 2 and their parents but normal in case 3. All 3 patients were diagnosed with monogenic lupus caused by DNASE1L3 defects. Literature searching identified 10 relevant publications in English and 0 publication in Chinese, involving 42 patients from 18 pedigrees (including the 3 cases from this pedigree). Nine variants were found: c.289_290delAC (p.T97Ifs*2), c.643delT (p.W215Gfs*2), c.320+4delAGTA, c.321-1G>A, Ex5 del, c.433G>A, c.581G>A (p.C194Y), c.537G>A (p.W179X), and Ex3-4 del. The hotspot variants were c.643delT (43% (36/84)) and c.289_290delAC (36% (30/84)). Kidney was affected in 31 cases (74%) of the 42 cases. Among the 25 patients, joints were affected in 16 cases (64%), fever were reported in 13 cases (52%) hematologic system was involved 13 cases (52%), rash was present in 10 cases (40%), intestinal tract was involved in 8 cases (32%), lungs were involved in 6 cases (24%), eyes were involved in 4 cases (16%), and the heart was involved in 4 cases (16%). The 2 cardiopulmonary affected patients from literature showed poor prognosis, with 1 died, and 1 right heart failure. Conclusions: The clinical manifestations of monogenic lupus caused by DNASE1L3 defect are highly heterogenous, primarily with renal, blood, joint, intestinal, and cardiopulmonary involvement. There is no correlation between the genotype and the phenotype. DNASE1L3 defects were predominantly mediated by null varations including nonsense, splicing, frameshift and exon deletions. The hotspot variants are c.643delT and c.289_290delAC. DNASE1L3 defects should be cautioned in early-onset lupus-like patients with renal, joint and hematologic involvement. Cardiopulmonary involved patients require close monitoring for poor prognosis. Copy number variations should be carefully analyzed after negative whole exome sequencing.

Lipopolysaccharide (LPS)-induced inflammation causes massive threatening diseases, such as sepsis, acute lung injury and multiple organ dysfunction syndrome. Efficient treatment to prevent inflammation is crucial in LPS-induced inflammatory diseases. Heat-clearing Chinese medicines (CMs) have been used to ameliorate LPS-induced inflammation in China for centuries. Heat-clearing CMs regulate inflammatory pathways, thereby inhibiting the release of inflammatory factors. This review aimed to introduce promising heat-clearing CMs countering LPS-induced inflammation in the last 5 years, exploring the underlying molecular mechanisms.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause acute respiratory distress syndrome, hypercoagulability, hypertension, and multiorgan dysfunction. Effective antivirals with safe clinical profile are urgently needed to improve the overall prognosis. In an analysis of a randomly collected cohort of 124 patients with COVID-19, we found that hypercoagulability as indicated by elevated concentrations of D-dimers was associated with disease severity. By virtual screening of a U.S. FDA approved drug library, we identified an anticoagulation agent dipyridamole (DIP) , which suppressed SARS-CoV-2 replication . In a proof-of-concept trial involving 31 patients with COVID-19, DIP supplementation was associated with significantly decreased concentrations of D-dimers ( < 0.05), increased lymphocyte and platelet recovery in the circulation, and markedly improved clinical outcomes in comparison to the control patients. In particular, all 8 of the DIP-treated severely ill patients showed remarkable improvement: 7 patients (87.5%) achieved clinical cure and were discharged from the hospitals while the remaining 1 patient (12.5%) was in clinical remission.

ObjectiveTo study the clinical application value of the penile erectile strength measurement (PESM) band in the differentiation of psychogenic from organic erectile dysfunction (ED).

METHODSEighty ED patients unable to achieve or maintain adequate penile erection to complete sexual intercourse were included in the experimental group and another 40 healthy subjects with normal erectile function enrolled as controls. The ED cases were classified into mild, moderate and severe ED according to the IIEF-5 scores and divided into psychogenic and organic ED based on the results of the nocturnal penile tumescence (NPT) test. Then all the subjects underwent a three-night continuous monitoring with the PESM band and, according to the band fracture rate, the ED cases were also classified into psychogenic and organic ED. The rates of missed diagnosis, misdiagnosis and diagnostic coincidence of PESM were calculated with the results of NPT as the standard for differentiating psychogenic from organic ED.

RESULTSThe results of NPT tests revealed 51 cases of psychogenic and 29 cases of organic ED in the experimental group. The band fracture rate in PESM was 95.0% in the mild, 80.9% in the moderate and 52.8% in the severe ED patients. Of the 51 cases of psychogenic ED detected by NPT test, 43 were diagnosed as psychogenic and the other 8 as organic ED with the PESM band, with a coincidence rate of 84.3%. Of the 29 cases of organic ED revealed by NPT test, 5 were diagnosed as psychogenic and the other 24 as organic ED by PESM, with a coincidence rate of 82.8%. Normal erectile function with three-level fracture of the band was observed in the PESM of the normal controls, which showed a coincidence rate of 100% with the results of NPT tests. Based on the standard of the NPT test, the rates of missed diagnosis, misdiagnosis and diagnostic coincidence of the PESM band in differentiating psychogenic from organic ED were 15.7%, 17.2%, and 83.8%, respectively, with a Kappa value of 0.656 (P <0.05).

CONCLUSIONSThe penile erectile strength measurement band can be used as a screening tool for initial differentiation of psychogenic from organic ED.

ObjectiveTo investigate the association of circumcision with the incidence of human papillomavirus (HPV) infection in men.

METHODSWe collected the samples from the surface of the coronal sulcus, glans penis, penile shaft and scrotum of 351 males examined for HPV infection in our hospital from January 2016 to August 2017, of whom 118 had received circumcision while the other 233 had not. We compared the incidence rate of HPV infection between the circumcision and non-circumcision groups and analyzed the association of the age of circumcision with the incidence of HPV infection.

RESULTSHPV infection was found in 135 (38.46%) of the males, 29 (24.58%) in the circumcision group and 106 (45.49%) in the non-circumcision group, significantly lower in the former than in the latter (χ² = 14.48, P < 0.01). The incidence rate of HPV infection was also remarkably lower in the males circumcised at ≤17 years (13.16% ［5/38］) than in those circumcised at >17 years of age (30.0% ［24/80］) (χ² = 3.942, P = 0.047).

CONCLUSIONSMale circumcision helps reduce the incidence rate of HPV infection in men and earlier surgery may achieve even better effect.

Objective: To make a real-world study on the efficacy and safety of traditional Chinese medicine (TCM) combined with sildenafil in the treatment of erectile dysfunction (ED) that failed to respond to TCM medication. METHODS: This study included 1 038 ED patients with the International Index of Erectile Function-5 (IIEF-5) scores ≤21 and improvement <30% after 4 weeks of TCM medication, differentially diagnosed with kidney-yang or kidney-yin deficiency syndrome. We administered TCM combined with sildenafil (Viagra, Pfizer Pharmaceutical Co., Ltd) at 100 mg 1 hour before sexual intercourse. After 2 and 4 weeks of medication, we recorded the scores in IIEF-5, erection hardness, Sexual Encounter Profile question 2 (SEP-2: whether vaginal penetration is successful), SEP-3 (whether sexual intercourse is successful), and TCM Syndromes Scale as well as the indexes of routine blood, urine, liver function, and renal function of the patients, and compared them with those obtained before treatment. RESULTS: No serious adverse reactions were observed in any of the patients. Compared with the baseline, the patients achieved significantly increased IIEF-5 scores after 2 and 4 weeks of medication (15.01 ± 2.25 vs 16.96 ± 2.55 and 19.41 ± 2.82, P <0.05), penileelectionhardness remarkably improved at 4 weeks (3.36% vs 44.58%, P<0.05), and the positive answers to SEP-2 and SEP-3 both markedly increased at 2 (38.11% vs 90.49%, P<0.05; 22.01% vs 63.77% , P<0.05) and 4 weeks (38.11% vs 96.95% , P<0.05; 22.01% vs 89.73%, P<0.05). CONCLUSIONS TCM combined with sildenafil is safe and effective in the treatment of ED in Chinese men, which can significantly improve the IIEF-5 score and erection hardness of the patients.

Objective: To investigate the values of serum calculated free testosterone (cFT), testosterone secretion index (TSI), and free testosterone index (FTI) in the diagnosis of ED with androgen deficiency by observing their changes in the patient. METHODS: We conducted this study among 185 men complaining of ED and 35 20－40 years old healthy males presenting at the clinic for premarital medical checkup. We asked them about their medical history, to fill in the International Index of Erectile Function (IIEF-5) Questionnaire, and to complete the nocturnal penile tumescence (NPT) test. According to the data obtained, 150 of the complainants were diagnosed as ED patients and 25 of the healthy examinees were included in the control group. We determined the levels of total serum testosterone (TT), luteinizing hormone (LH), sex hormone-binding globulin (SHBG), serum albumin (ALB), cFT, bio-available testosterone (bio-T), TSI, and FTI in the two groups of subjects. Using cFT ≤0.3 nmol/L, TSI ≤2.8, and FTI ≤0.4 as the critical values and TT ≤11.5 nmol/L as the gold standard for androgen deficiency, we calculated cFT-, TSI-, and FTI-related rates of missed diagnosis, misdiagnosis, and diagnostic coincidence. RESULTS: With TT ≤11.5 nmol/L as the criterion, the cFT-, TSI-, and FTI-related rates of coincidence in the diagnosis of androgen deficiency in the ED patients were 90.8%, 85.8%, and 80.8%, those of missed diagnosis were 4.0%, 33.3%, and 44.0%, and those of misdiagnosis were 10.5%, 19.4%, and 12.6%, with the Kappa of values 0.755, 0.564, and 0.427, respectively (P <0.05). The levels of serum TT, cFT, Bio-T, TSI, and FTI were decreased with increased age of the 20－40 years old ED patients, with statistically significant differences among different age groups except the serum TT level. However, no statistically significant differences were found in the levels of TT, cFT, Bio-T, TSI, and FTI among the patients with different IIEF-5 scores. CONCLUSIONS The level of cFT has a higher value than those of TT, TSI, and TSI in the diagnosis of ED with androgen deficiency in 20－40 years old men.
