Premature ejaculation refers to a sexual dysfunction in which men experience a short intravaginal ejaculation latency and a lack of control over ejaculation during sexual activity. The onset of this condition is often accompanied by anxiety and depression, which can seriously affect the quality of the patient′s sexual life and the relationship between partners. Based on the "integration of body and spirit" theory in traditional Chinese medicine, our team believes that this condition is a comorbidity of physical and spiritual factors. We propose that the core pathogenesis of this disease lies in the "loss of form and essence, impairment of spirit, and depression of the mind, "while the primary treatment principle involves "nourishing form and regulating spirit." As a result, a new diagnosis and treatment approach of "four-dimensional integration" is summarized in this study. The disease is treated through the four dimensions of shape, body, spirit, and emotion. Traditional Chinese medicine is used to adjust the shape in cases where the physical form is damaged. For individuals with depression of heart and liver qi, the treatment focuses on soothing the heart and smoothing liver qi, and the modified Wangyou Powder and Xuanzhi Decoction is used. In cases where the heart and kidney function are compromised, the treatment involves nourishing both the heart and kidney while restoring interaction between the heart and the kidney, and modified Jihuo Yansi Elixir is used. To reduce the sensitivity of the glans penis, the patient′s body is washed with a traditional Chinese medicine formula, and a delicate fumigation formula is decocted for external washing. For those who are not in tune with their god, psychological counseling can be used to regulate their spirit and advocate "self-partner" and psychotherapy. If there are issues with intimacy, partners should focus on cooperating during foreplay, sexual intercourse, and post-coital interactions. Overall, the treatment aims to harmonize the body and spirit, addressing both physical and psychological factors through a comprehensive, multi-dimensional approach. This method provides new perspectives and ideas for the clinical diagnosis and treatment of this condition.

ObjectiveTo explore the interaction among root fungi of Stellaria dichotoma var. lanceolata， soil factors， and main components of medicinal materials in lithosol habitats. MethodHigh-throughput sequencing technology was employed to determine the fungal community of the root system of S. dichotoma var. lanceolata at different levels （bulk soil， rhizosphere soil， rhizoplane soil， and root interior） and the soil properties of the root system （bulk and rhizosphere）， and the relationship among the fungal community， soil properties， and the main components of medicinal materials was analyzed. ResultThe total phosphorus， available phosphorus， alkaline nitrogen， dissolved organic carbon， and soil water content in the rhizosphere soil of S. dichotoma var. lanceolata were slightly higher than those in the rhizosphere， but the difference was not significant. Ascomycota is the dominant phylum of root fungi in S. dichotoma var. lanceolata. In the progressive level of bulk-rhizosphere-rhizoplane-root interior system， although the fungal diversity gradually decreased， the abundance of Hypocreales， a new phylum （unclassified_ k_ Fungi）， Helotiales， and Natipusilales gradually increased， among which Hypocreales is the most important fungal group in the root system of S. dichotoma var. lanceolata. The structural equation model （SEM） shows that the physicochemical factors of the root-soil play an important regulatory role in the fungal community and the main components of medicinal herbs， with soil total nitrogen， alkaline nitrogen， soil water content， and pH being the main regulatory factors. Soil nitrogen content is the key to promoting the main components of the medicinal herbs， and Penicillium fungi are the key fungal group to regulate the main components of the medicinal herbs. ConclusionIt highlights that the physicochemical properties of the soil of S. dichotoma var. lanceolata play a crucial role in the fungal community and the components of medicinal materials. Hypocreales fungi in the root of S. dichotoma var. lanceolata were an important group， and Penicillium fungi had a certain role in mediating the components of medicinal materials.

Objective:To explore the clinical safety and efficacy of transurethral oral mucosa urethroplasty for urethral meatus and navicular fossa stricture reconstruction.Methods:Retrospective analysis of 9 patients who underwent transurethral repair of urethral meatus and navicular fossa stricture by oral mucosa in our hospital from October 2021 to December 2022. The average age was (58.4±10.4) years old. 5 patients had a history of transurethral endoscopic surgery, 2 had penile lichen sclerosis, and 2 had no obvious causes. Nine patients were diagnosed with urethral meatus and navicular fossa stricture through retrograde urethrography before surgery. The average maximum preoperative urine flow rate was(3.2±0.7)ml/s. Surgical procedure: The incision was firstly made at 6 o'clock using ophthalmic scalpel, the entire layer of urethral scar was opened, and gradually penetrated into the urethral cavity until it reached the normal mucosa of the urethra. A fan-shaped wound was obtained by cutting the scar of 4 to 8 o'clock. The enlarged urethral lumen could smoothly pass through the F24 urethral probe. Measure the stricture length and width, and trim the oral mucosa to the appropriate shape. One arm of the 5-0 absorbable suture passed through the tip of the oral mucosal flap and the normal urethral mucosa outside the apex of the urethral fan-shaped wound, and then passed through the skin on the ventral side of the penis. The other arm of the suture passed through the apex of the fan-shaped wound and passes through the skin on the ventral side of the penis. Tighten the suture to bring the oral mucosa into the urethral cavity and cover the wound surface. If the narrow length was longer, we could suture three stitches to fix the oral mucosa with the V-shaped apex of the fan-shaped wound in a similar way, and the rest could be sutured and fixed with the urethral wound edge in direct vision. The actual measured average length of urethral stricture during the surgery was(1.6±0.5) cm. The appearance of the glans penis, stricture recurrence, maximum urine flow rate, and patient's urination symptoms were recorded after surgery 1 to 3 months. Functional success was defined as the lack of patient reported obstructive voiding symptoms, satisfaction with the appearance of the glans penis, and a slit like external urethral orifice.Results:All 9 patients successfully completed the surgery and the average maximum urine flow rate was(21.5±3.7)ml/s after 3 months of follow up. The overall successful rate was 100%.One patient experienced spraying urination 1 month later after removing the catheter. Examination revealed that protrusion and separation were found at the urethral anastomosis, and symptoms disappeared after urethral dilation. The other patients did not have any obvious complications, satisfactory with the appearance of the penis head and urination.Conclusions:Transurethral oral mucosal repair of urethral meatus and navicular fossa stricture could be a safe, and effective surgical method. It not only solves the problem of urination, but also takes into account the cosmetic effect of penis.

Objective:To explore the clinical features and survival of newly diagnosed follicular lymphoma (FL) patients with diffuse large B-cell lymphoma (DLBCL) component.Methods:1845 newly diagnosed FL patients aged ≥ 18 years with grades 1-3a in 11 medical centers in China from 2000 to 2020 were included, and patients with DLBCL component were screened. The clinical data and survival data of the patients were retrospectively analyzed, and the prognostic factors were screened by univariate and multivariate analysis.Results:146 patients (7.9% ) with newly diagnosed FL had DLBCL component. The median age was 56 (25-83) years, 79 males (54.1% ) . The pathology of 127 patients showed the proportion of DLBCL component. Patients were divided into two groups according to whether the proportion of DLBCL component was ≥ 50% . The study found that patients with DLBCL component ≥ 50% had higher grade 3 ratio (94.3% vs 91.9% , P=0.010) , Ki-67 index ≥ 70% ratio (58.5% vs 32.9% , P=0.013) and PET-CT SUVmax ≥ 13 ratio (72.4% vs 46.3% , P=0.030) than patients with DLBCL component<50% . All patients received CHOP or CHOP like ± rituximab chemotherapy. The overall response rate (ORR) was 88.2% , and the complete response (CR) rate was 76.4% . In the groups with different proportions of DLBCL component, there was no significant difference in the remission rate after induction treatment and the incidence of disease progression within 2 years after initiation of treatment (POD24) ( P<0.05) . The overall estimated 5-year progression free survival (PFS) rate was 58.9% , and the 5-year overall survival (OS) rate was 90.4% . The 5-year OS rate of POD24 patients was lower than that of non POD24 patients (70.3% vs 98.5% , P<0.001) . Compared with non maintenance treatment of rituximab, maintenance treatment of rituximab could not benefit the 5-year PFS rate (57.7% vs 58.8% , P=0.543) , and the 5-year OS rate had a benefit trend, but the difference was not statistically significant (100% vs 87.8% , P=0.082) . Multivariate analysis showed that failure to reach CR after induction treatment was an independent risk factor for PFS ( P=0.006) , while LDH higher than normal was an independent risk factor for OS ( P=0.031) . Conclusion:FL patients with DLBCL component ≥50% have more invasive clinical and pathological features. CHOP/CHOP like ± rituximab regimen can improve the clinical efficacy of patients. Rituximab maintenance therapy can not benefit the PFS and OS of patients. Failure to reach CR after induction therapy was the independent unfavorable factor for PFS.

Objective:To investigate whether knee osteoarthritis has an impact on the patient′s depression and whether it′s progression will affect the patient′s depression, and to provide a reference for clinical work.Methods:Patients diagnosed with osteoarthritis in Dalian Central Hospital from 2016 to 2019 were divided into 4 groups according to Kellgren-Lawrence staging, and the patients were scored on WOMAC scale, AKSS clinical scale, and AKSS. The score of the scale and the score of the HAMD scale were collected and statistically analyzed using SPSS 17.0.Results:χ2 test was used to show that there was no difference in the gender composition of patients in different stages ( P<0.05). The AKSS clinical scale score, AKSS functional scale score, WOMAC scale score and HAMD scale score were statistically analyzed for each stage. The results showed that the average AKSS clinical scores of patients in each stage were as follows: stage Ⅰ: (90.01 ± 8.41) points; stage Ⅱ: (79.98 ± 10.93) points; stage Ⅲ: (71.78 ± 13.64) points; stage Ⅳ: (54.18 ± 12.58) points. The AKSS functional scores were as follows, stage Ⅰ: 100 points; stage Ⅱ: 80 points; stage Ⅲ: 70 points; stage Ⅳ: 45 points; the average WOMAC scale scores of patients in each stage were as follows, stage Ⅰ: (28.69 ± 19.22) points ; stage Ⅱ: (49.43 ± 22.69) points; stage Ⅲ (70.13 ± 24.84) points; stage Ⅳ: (107.79 ± 24.39) points. The average HAMD scale scores of patients in each stage were as follows, stage Ⅰ: (4.89 ± 3.42) points; stage Ⅱ: (7.65 ± 4.20) points; Stage Ⅲ: (9.05 ± 5.03) points; stage Ⅳ: (12.35 ± 5.41) points. The analysis showed that there were significant statistical differences in the scale scores between each period ( P<0.05). There was a correlation between the patient′s depression status and the patient′s age, pain, and joint function, and there were statistical differences ( P<0.05). Conclusions:There is a significant correlation between depression and pain and function in patients with knee osteoarthritis. The progress of the osteoarthritis course will aggravate the patient′s depression state. Conversely, the patient′s depression state can also aggravate the symptoms of osteoarthritis patients and affect the clinical efficacy of the patients.

At present, the somatic function assessment of the elderly mostly depends on the doctor's observation and the scale evaluation, and there isn't the objective and quantitative assessment criteria. In this paper, we design and construct a digital system for the geriatric somatic function assessment, which is based on digital ground, inertial unit, mobile terminal and PC terminal. The gait and balance parameters of the elderly were obtained by the Time Up and Go test and five postures test. Based on the linear regression model of gait and balance parameters, the system was used to evaluate the somatic function of the elderly. The experimental results show that the system not only can accurately distinguish elderly between fall and non-fall, but also has a high correlation between the score of the system and the score of clinical geriatric physical function scale.

Objective To investigate the relationship between hypoxia and insulin resistance in males with metabolic syndrome ( MS ). Methods Parameters at physical, hematological, glucose metabolism, lipid metabolism, and insulin resistance were measured in 295 middle-aged men who took health examination. The trends of laboratory indexes grouped by hemoglobin quartile and MS components were compared. The correlation between hypoxia and insulin resistance was analyzed. Results With the increase of hemoglobin, the occurrence rates of MS, TG, INS, and HOMA-IR were also significantly increased ( P < 0. 05 ), while HDL-C and HOMA-IS reduced remarkably(P<0. 05). With the increase of MS components, hematological parameters(RBC, Hb, Hct), INS, and HOMA-IR were significantly increased( P<0. 05) while HOMA-IS were significantly decreased( P<0. 05). Blood lactate and HIF-1αwere significantly increased with the increase of hemoglobin as well as MS components(P<0. 05);Hematological parameters were positively correlated with blood lactate and HIF-1α, and Hypoxia related indicators including hematological parameters, Lac, HIF-1α showed a positive correlation with HOMA-IR and a negative correlation with HOMA-IS( P < 0. 05). Conclusion Chronic hypoxia does exist in metabolic syndrome, and the degree of hypoxia is associated with insulin resistance. Hematological parameters are also significantly correlated with insulin resistance which could be as a result of chronic hypoxia.

OBJECTIVETo analyze the cause of misdiagnosis of occupational chronic n-hexane poisoning and to investigate the diagnosis and differential diagnosis of this disease.

METHODSThe clinical data of 16 patients with occupational chronic n-hexane poisoning who had been misdiagnosed with other diseases were collected. The hospital they first visited, cause of misdiagnosis, clinical features, and the misdiagnosis rate among inpatients during the same period were retrospectively analyzed.

RESULTSSixteen of 62 patients hospitalized during the same period were misdiagnosed at the first visit; 11 cases were in the upper first-class hospitals, and 5 cases in the upper second-class hospitals; 5 cases were misdiagnosed as Green Barry syndrome, 2 cases as motor neuron disease, 2 cases as drug-induced peripheral neuropathy, 3 cases as periodic paralysis, and 4 cases had uncertain diagnosis.

CONCLUSIONMost doctors who work in ordinary hospitals do not know occupational chronic n-hexane poisoning, which is often misdiagnosed as general neuropathies or difficult diseases. The key to correct diagnosis is to know the patient's occupational history and clinical features.
