ABSTRACT
【Objective】 To analyze the application value of penile vibrating perception threshold measurement in the diagnosis of erectile dysfunction (ED) and provide reference for the seversity of ED patients. 【Methods】 The clinical data, Erectile Hardness Scale (EHS) score, International Index of Erectile Function Questionnaire-5 (IIEF-5) score, and the vibrating perception threshold (VPT) of the penis of 257 patients with decreased erectile function as the main complaint or accompanying symptoms treated during Jan. and Dec.2021 were retrospectively collected and analyzed.Patients with EHS=4 and IIEF-5≥22 were classified into the normal group, and the rest into the ED group.The differences in VPT in patients with different EHS scores were compared, and the correlation between IIEF-5 and VPT was analyzed.The diagnostic value of VPT for ED was evaluated with receiver operating characteristic (ROC) curve. 【Results】 The difference in penile VPT among patients with different EHS scores was statistically significant (P<0.05).With the decrease of EHS score, VPT showed an increasing trend.Glans VPT was negatively correlated with IIEF-5 score (ρ=-0.22, P<0.001), and penile shaft VPT was also negatively correlated with IIEF-5 score (ρ=-0.26, P<0.001).The VPT of glans penis [(4.17±1.37) V vs.(3.47±1.24) V, P=0.009] and the VPT of penis body [(3.73±1.41) V vs.(2.99±1.14)V, P=0.003] in the ED group were both higher than those in the normal group.The area under the ROC curve (AUC) of the glans VPT was 0.642.When the cut-off value was 3.537 V, the sensitivity was 63.4%, and the specificity was 63.6%.The AUC of the penile shaft VPT was 0.659.When the cut-off value was 2.775 V, the sensitivity was 72.3%, with a specificity of 54.5%. 【Conclusion】 The penile VPT of ED patients is higher than that of normal ones, and there is a correlation between VPT and the severity of ED.Severe ED is associated with higher VPT.The measurement of penile VPT is helpful for the clinical diagnosis of ED patients.
ABSTRACT
To explore the thinking and working mode of clinical pharmacists of traditional Chinese medicine participating in clinical,the drug treatment was analyzed by an acute hyperkalemia patient suspected of CKD 5 caused by traditional Chinese medicine.This case is a CKD 5 patient.Since proteinuria was found for 8 years,bilateral lower limb edema was intermittent for 4 years,and the recurrence was aggravated for 1 week,the patient was admitted to the hospital.In the Department of Traditional Chinese Medicine,the patient received standard and reasonable antiplatelet,lipid regulation,kidney protection,anemia improvement,blood pressure reduction,and heart load reduction,Traditional Chinese medicine decoction,traditional Chinese patent medicines.The patient's condition improved,but the newly emerging hyperkalemia prolonged the patient's hospital stay.After the treatment of blood potassium lowering drugs,the blood potassium still increased repeatedly.For this reason,clinical Chinese pharmacists assisted clinicians to find out the factors that caused the repeated increase of blood potassium in combination with existing domestic and foreign literature.Finally,considering the high possibility of traditional Chinese medicine,they stopped using traditional Chinese medicine and continued to use blood potassium lowering drugs,and the blood potassium returned to normal.Hyperkalemia caused by traditional Chinese medicine is not common in clinical practice and often is ignored.It can be seen that clinical pharmacists can participate in pharmaceutical care to find adverse drug reactions as soon as possible and ensure the safety of drug use.

ABSTRACT
【Objective】 To introduce a modified microdot two-layer microsurgical vasovasostomy (MVV) and to analyze its effectiveness in patients with vas deferens obstruction caused by inguinal herniorrhaphy. 【Methods】 Clinical data of patients treated during Mar.2015 and Oct.2020 were retrospectively analyzed. According to different surgical methods, the patients were divided into the modified group and traditional group. The general data, intraoperative conditions, efficacies and complications of the two groups were compared. 【Results】 There were 59 cases in the modified group, 54(91.5%) of whom were successfully followed up, and 41 cases in the traditional group, 38(92.7%) of whom were successfully followed up. There were no significant differences in age, inguinal herniorrhaphy history, and unilateral/bilateral ratio between the two groups (P>0.05). The average operation time for unilateral lesions in the modified group was shorter than that in the traditional group [(89.44±24.86) vs. (112.04±43.40) min, P=0.032]. The postoperative patency rate (83.3% vs.73.7%, P>0.05) and natural pregnancy rate (33.3% vs.28.9%, P>0.05) of the modified group and traditional group were comparable. Incision fat liquefaction occurred in 2 cases (3.70%) in the modified group and in 1 case (2.63%) in the traditional group (P>0.05). 【Conclusion】 The modified microdot two-layer MVV is a safe surgical method with comparable effectiveness as the traditional approach. By adjusting the position of the marking points and the order of suturing, it helps the management of sutures, reduces the difficulty of vasovasostomy, shortens operation time, and can be applied to repair vas deferens obstruction caused by inguinal herniorrhaphy.
ABSTRACT
Objective:To investigate the effect of autologous costal cartilage cortex as nasal tip support and modified graft for nasal tip contour improvement.Methods:From June 2020 to June 2021, 116 patients (male 26, female 90, aged 20-45 years) who received rhinoplasty in the cosmetic surgery department of Myoung Beaucare Clinic of Beijing, were examined the costal cartilage by CT, and the costal cartilage was cut. The costal cartilage cortex was made into " strip" and " cap" grafts to shape the nasal tip, and the nasal dorsum was raised by polytetrafluoroethylene or silicone prosthesis for comprehensive rhinoplasty.Results:A total of 116 patients were followed up for an average of 11.7 months. After the operation, there was no space occupying in the nasal cavity, no graft protrusion, no obvious foreign body feeling in the nasal valve, and the nasal tip could swing left and right. At the same time, the nasal tip showed obvious signs, the lower lobule was full, and there were no complications such as cartilage appearance, exposure, infection, etc. Due to the untreated deviation of nasal septum, 3 cases had deviation of nasal columella and asymmetric nostrils. The shape of nasal tip was stable in the remaining 113 cases, and satisfactory results were obtained.Conclusions:By using autologous costal cartilage cortex as nasal tip support and modification graft for nasal tip contour improvement, the shaped nasal tip is soft and movable, and does not affect the airway. It is a good surgical technique in nasal tip plastic surgery, which is worthy of clinical application.
ABSTRACT
Objective:To explore the application of nasal aesthetic polygon theory in the reconstruction of new domes on nasal tip with autogenous costal cartilage.Methods:From June 2019 to June 2021, 116 patients (26 males and 90 females) received rhinoplasty, CT-assisted examination of the costal cartilage, nasal bone and nasal cartilage was performed, and the autogenous costal cartilaginous cortex was used to make dome reconstruction grafts that were transplanted to the original alar cartilage and partially fixed to the original nasal septum cartilage to form a satisfactory and natural nasal shape.Results:All the patients were followed up for 6-24 months. No cartilaginous, overrotated or underrotated appearance was found in nasal tip. The shape of nasal tip was clear and good, with an obvious performance point and full lower lobule. The nose was tall and straight, and looked natural and beautiful in three dimensions.Conclusions:The nasal aesthetic polygon theory is used to guide the reconstruction of new domes with autogenous costal cartilage in nasal tip surgery. Compared to the cap and shield grafts, the nasal tip is more close to the normal anatomical structure, the shape and texture are more similiar to the natural state and the nasal tip is softer by using autogenous costal cartilage, and so it is an ideal surgical procedure for nasal tip reconstruction.

ABSTRACT
【Objective】 To explore a new treatment of primary bilateral macronodular adrenal hyperplasia (PBMAH) and its efficacy. 【Methods】 Clinical data of 20 PBMAH patients treated in our hospital during Mar.2010 and Apr.2021 were retrospectively analyzed. All patients underwent laparoscopic subcutaneous displacement of vascularized adrenal. The clinical symptoms, plasma free cortisol, adrenocorticotrophic hormone (ACTH), and 24 h urinary free cortisol were regularly monitored after surgery. 【Results】 Of all 20 patients, 19 were followed up for 18 to 120 months (median 60 months). Three months after surgery, reexamination showed 1 patient had decreased plasma free cortisol and increased ACTH, but had no symptoms of low corticosteroids. After another 3 months, the plasma free cortisol and ACTH returned to normal. After 4 to 48 months, the parameters recovered in all patients and the clinical symptoms disappeared. 【Conclusion】 Laparoscopic vascularized adrenal displacement is a new and effective method for the treatment of PBMAH. It can alleviate the Cushing syndrome with no obvious adverse reactions.
ABSTRACT
The purpose of this study was to investigate the effect of isorhyncophylline on hippocampal endogenous metabolites in spontaneously hypertensive rats (SHR) by 1H NMR metabolomics and molecular docking. Twelve SHR were randomly divided into a model group and a treatment group. Six Wistar-Kyoto rats were selected as a control group. The rats in the treatment group were administered isorhyncophylline (0.3 mg·kg-1) while the rats in the other two groups were treated with the same amount of sterilized saline solution. Animal experiment was authorized by the Ethics Committee of Shandong University of Traditional Chinese Medicine (No. SDUTCM20210721002). Hippocampal tissues were removed after administration for 8 weeks and assayed by 1H NMR based metabolomics technology combined with a pattern recognition method to find characteristic metabolites, and the metabolic targets were retrieved from the Kyoto Encyclopedia of Genes and Genomes database. Molecular docking technology was used to evaluate binding of isorhyncophylline to the core targets. The results of a principal components analysis (PCA) and partial least squares discriminant analysis (PLS-DA) showed a clear cluster of samples among three groups. There were seven differentially altered metabolites, and glucose metabolism and glutamate metabolism were the principal related pathways. Molecular docking indicated that isorhyncophylline had good binding properties with nine key candidate target proteins. According to the above research results, isorhyncophylline can influence energy metabolism and glutamate metabolism in the hippocampus.
ABSTRACT
Objective To screen the targets of traditional Chinese medicine-derived potential plant molluscicides based on network pharmacology and explore the mechanisms of molluscicidal actions. Methods The traditional Chinese medicines with molluscicidal actions were screened based on retrospective literature reviews, and their molluscicidal efficiency was summarized. The active ingredients and potential targets of traditional Chinese medicines were captured from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, Unified Protein Database and literature mining using network pharmacology. The drug-active ingredient-target network was created using the software Cytoscape 3.7.2, and the key targets were subjected to Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis using the Metascape software. Results A total of 27 types of snail control drugs derived from traditional Chinese medicines were screened from publications and classified into 14 categories. Network pharmacology identified 190 active ingredients, and the active ingredients with a high degree in the drug-active ingredient-target network included quercetin, linoleyl acetate, luteolin, beta-carotene, (24S)-ethylcholesta-5,22,25-trans-3beta-ol, fumarine and arctiin, with 181 corresponding potential targets screened. KEGG pathway enrichment analysis revealed that these targets were mainly located in 16 pathways, including the neuroactive ligand-receptor interactions, regulation of adipocyte lipolysis and adrenergic signal in myocardial cells. Conclusions This study preliminarily demonstrates the multi-ingredient, multi-target and multi-pathway mechanisms of action of 27 molluscicides. The screened key ingredient may provide the basis for isolation, purification and pharmacological studies of molluscicides, and the screened key targets and key pathways may facilitate the illustration of mechanisms of actions of traditional Chinese medicine-derived molluscicides and development of novel green molluscicides.
ABSTRACT
Objective:To investigate the intention of medical students to be vaccinated against COVID-19 and to analyze the influencing factors.Methods:A self-filled electronic questionnaire survey was conducted among medical students from a medical school in Shanghai randomly selected from June 21 to 29, 2021. The questionnaire contained items of basic information, intention for COVID-19 vaccination, awareness of COVID-19 prevention measures and awareness of COVID-19 vaccine. Logistic regression was used to analyze the influencing factors.Results:The average age of the 966 respondents was (20.4±2.9) years, and 63.6% (614/966) of them were female;23.7% (229/966) of them had family members or relatives who had participated in anti-pandemic work or volunteer service;90.6% (875/966) of the respondents expressed they were very willing or willing to be vaccinated against COVID-19. The majority of the respondents thought that “COVID-19 infection is very serious” (94.3%, 911/966), “good protection can effectively prevent COVID-19 infection” (92.4%, 893/966), and “they can fully implement all kinds of protection measures” (73.5%, 710/966). About half of the respondents (51.8%, 501/966) knew about the adverse reactions and contraindications of COVID-19 vaccine. The low protected capability (47.4%, 458/966), short duration of protection (50.6%, 489/966), and many side effects (48.7%, 470/966) were the major concerns about COVID-19 vaccine. Logistic regression analysis showed that people thought that “COVID-19 infection is very serious” ( OR=5.30, 95 %CI:2.60-10.81, P<0.001), thought that “good protection can effectively prevent COVID-19 infection” ( OR=2.46, 95 %CI:1.26-4.81, P=0.009), thought that “they can fully implement all kinds of protection measures” ( OR=2.55, 95 %CI:1.53-4.25, P<0.001) were more willing to receive COVID-19 vaccination. While those concerned about vaccine quality did the opposite ( OR=0.29, 95 %CI:0.13-0.65, P=0.003). Conclusions:Medical students have a high intention of vaccination against COVID-19. The vaccine-related knowledge quality should be emphasized in future publicity to further enhance the intention of COVID-19 vaccination.
ABSTRACT
Objective@#To explore relationship between screen time and myopia in children aged 11-14 years in China.@*Methods@#The data were extracted from "National Nutrition and Health Systematic Survey and Application for 0-18 Years Old Children". A total of 12 397 children aged 11-14 years old from 14 provinces and 28 districts/counties in seven regions of China were surveyed by using multi stage stratified random sampling method. Daily screen time and visual acuity information were collected through a questionnaire.@*Results@#The myopia rate of 11-14 years old children in China was 45.0%, among which the rate of girls was higher than that of boys, and the rate of urban was higher than that of rural, and it increased with age ( χ 2=178.82,79.25, 495.96 , P <0.01). The daily screen time median of 12 397 children was 40.0 minutes, with boys(40.0 min) longer than girls( 35.0 min ) and urban children(40 min) longer than rural children(33.0 min) ( χ 2=20.86，102.68， P <0.01). The myopia rate of boys ( 42.5 %) with daily screen time greater than or equal to 60 minutes was higher than that of boys (36.4%) with daily screen time less than 60 minutes, and the myopia rate of girls (55.6%) with daily screen time greater than or equal to 60 minutes was higher than that of girls (48.0%)( χ 2=23.62，34.15， P <0.01). After adjusting for age, gender, region, time of medium and high intensity physical activity, intake of sugary food and sugary beverages, daily sleep time, multivariable Logistic regression model showed that girls with daily screen time greater than or equal to 60 minutes ( OR=1.14, 95%CI =1.03-1.27) had a higher risk of myopia than those with less than 60 minutes. After adjusting for confounding factors, there was no correlation between daily screen time and the degree of myopia in boys or girls( P >0.05).@*Conclusion@#Daily screen time greater than or equal to 60 minutes may be a risk factor for myopia in girls aged 11 to 14 years old. Given the complexity of the factors that affect vision, researches are needed to examine the relationship between screen time and myopia.

Conclusions:In the comprehensive rhinoplasty of nasal septal cartilage for Chinese, the 12 mm L-shaped nasal septal cartilage scaffold is retained, and the average length, width and area of nasal septal cartilage for transplantation are 2.16 cm, 1.84 cm, 4.04 cm 2, 1.92 mm and 0.92 mm respectively.
ABSTRACT
Chronic obstructive pulmonary disease (COPD) has become the third-leading cause of death worldwide, which is a severe economic burden to the healthcare system. Chronic bronchitis is the most common condition that contributes to COPD, both locally and systemically. Neutrophilic inflammation predominates in the COPD airway wall and lumen. Logically, repression of neutrophilia is an essential fashion to COPD treatment. However, currently available anti-neutrophilic therapies provide little benefit in COPD patients and may have serious side effects. Thus, there is an urgent need to explore an effective and safe anti-neutrophilic approach that might delay progression of the disease. Sialic acid-binding immunoglobulin-like lectin (Siglec)-9 is a member of the Siglec cell surface immunoglobulin family. It is noteworthy that Siglec-9 is highly expressed on human neutrophils and monocytes. Ligation of Siglec-9 by chemical compounds or synthetic ligands induced apoptosis and autophagic-like cell death in human neutrophils. Furthermore, administration of antibody to Siglec-E, mouse functional ortholog of Siglec-9, restrained recruitment and activation of neutrophils in mouse models of airway inflammation in vivo. Given the critical role that neutrophils play in chronic bronchitis and emphysema, targeting Siglec-9 could be beneficial for the treatment of COPD, asthma, fibrosis, and related chronic inflammatory lung diseases.

Objective:To investigate the clinical value of cephalosporin combined with morinidazole in the prevention of surgical site infection (SSI) for gastrointestinal fistula.Methods:The retrospective cohort study was conducted. The clinicopathological data of 107 patients with gastrointestinal fistula who undergoing selective digestive tract reconstruction surgery in General Hospital of Eastern Theater Command from January to December 2017 were collected. There were 76 males and 31 females, aged from 18 to 79 years, with a median age of 46 years. Of 107 patients, 43 cases receiving cephalosporin for prevention of SSI were allocated into cephalosporin monotherapy group, 64 cases receiving cephalosporin combined with morinidazole were allocated into combination therapy group, respectively. Observation indicators: (1) incidence of SSI; (2) stratification; (3) pathogen culture results of SSI; (4) adverse drug reaction; (5) follow-up. Follow-up using outpatient examination and telephone interview was performed to detect other complications of patients. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results:(1) Incidence of SSI: 29 of 107 patients had postoperative SSI, including 15 cases with superficial SSI, 7 cases with deep SSI, and 7 cases with organ/space SSI. There were 18 cases of cephalosporin monotherapy group with SSI, including 7 cases with superficial SSI, 5 cases with deep SSI, and 6 cases with organ/space SSI. The above indicators were 11, 8, 2, 1 of combination therapy group, respectively. There was a significant difference in the overall SSI between the two groups ( χ2=7.925, P<0.05). There was also a significant difference in the organ/space SSI between the two groups ( P<0.05). There was no significant difference in the superficial SSI between the two groups ( χ2=0.305, P>0.05). There was no significant difference in the deep SSI between the two groups ( P>0.05). (2) Stratification: there were 10 cases and 33 cases with type Ⅱ incision and type Ⅲ incision in the 43 cases of cephalosporin monotherapy therapy group, respectively. The above indicators were 11 and 53 in the combination group, respectively. For the type Ⅱ incision, 1 patient of cephalosporin monotherapy group had SSI, and 2 cases of combination therapy group had SSI, showing no significant difference between the two groups ( P>0.05). For the type Ⅲ incision, 17 patient of cephalosporin monotherapy group had SSI, and 9 cases of combina-tion therapy group had SSI, showing a significant difference between the two groups ( χ2=11.499, P<0.05). (3) Pathogen culture results of SSI: of 29 patients with SSI, 21 were positive for bacterial culture, including 12 cases with single bacterial infection, 9 cases with mixed infection of multi-bacteria. A total of 33 strains were cultured. (4) Adverse drug reaction: there was no adverse drug reaction in the 107 patients. (5) Follow-up: 107 patients were followed up for 30 days after surgery. No complication occurred in the 107 patients. Conclusion:Cephalosporin combined with morini-dazole can be used to prevent the SSI for patients with gastrointestinal fistula.
ABSTRACT
Objective:To investigate the effect of early enteral nutrition in patients with severe traumatic brain injury requiring exploratory abdominal surgery.Methods:The clinical data of 104 patients with severe traumatic brain injury requiring exploratory abdominal surgery treated in the PLA Army 72th Group Military Hospital from January 2016 to December 2020 were retrospectively analyzed. Among them, 47 patients were given early enteral nutrition (24-48 hr) as the observation group, and 57 patients were given delayed enteral nutrition (>48 hr), as the control group. The levels of hemoglobin, albumin, prealbumin, total bilirubin, alanine transaminase, C-reactive protein, white blood cells, postoperative infectious complications and clinical outcomes were compared between the two groups on the 1st, 7th and 14th days after surgery.Results:On the 14th day after operation, the prealbumin level of the observation group was higher than that of the control group, and the leukocyte level of the observation group was lower than that of the control group, with statistical significance ( P=0.020, P=0.013). The hospital stay and hospitalization costs of the observation group were lower than those of the control group ( P=0.017, P=0.032). The incidence of pulmonary infection in the observation group was 10.6%, which was lower than 29.8% in the control group ( P=0.017). Conclusions:Early postoperative enteral nutrition in patients with severe traumatic brain injury requiring exploratory abdominal surgery can significantly improve the nutritional status of patients, reduce the incidence of pulmonary infection, the hospital stay and the hospitalization cost.
ABSTRACT
Objective:To investigate the surgical method and clinical outcome of using nasal septal cartilage combined with auricular cartilage for management of nasal tip shape.Methods:A clinical study was conducted from April 2014 to June 2019, in which we managed nasal tip shape with nasal septal cartilage and auricular cartilage, and these materials were used as septal extension graft, spreader graft and cap graft. In total, 622 patients (28 males, 594 females; age from 18 to 42 years, mean age 27.47 years) were assessed for eligibility.Results:The follow-up period was from 6 months to 6 years. Nasal shape of all 622 patients was improved significantly after the operation. The nasal tip was natural and round, and there were no complications such as damage of nasal septum mucosa, exposure of prosthesis and infection of surgical site. Only 12 patients were found downward rotation of nasal tip, and 610 patients achieved satisfactory aesthetic results.Conclusions:Using septal cartilage combined with auricular cartilage is a safe, effective and suitable method for management of nasal tip shape.
