Erectile dysfunction (ED) is prevalent among men, but its relationship with dietary habits is uncertain. The aim of our study was to assess whether dietary patterns enhance erectile function by reviewing the literature published before August 1, 2022, via PubMed, Web of Science, and EMBASE databases. The data compiled included author details; publication dates, countries, treatments, patient numbers, ages, follow-ups, and clinical trial outcomes, such as ED cases, odds ratios (ORs), confidence intervals (CIs), and International Index of Erectile Function-5 (IIEF-5) scores with means and standard deviations. An analysis of 14 studies with 27 389 participants revealed that plant-based diets (OR = 0.71, 95% CI: 0.66-0.75; P < 0.00001), low-fat diets (OR = 0.27, 95% CI: 0.13-0.53; P = 0.0002), and alternative diets such as intermittent fasting and organic diets (OR = 0.54, 95% CI: 0.36-0.80; P = 0.002) significantly reduced ED risk. High-protein low-fat diets (hazard ratio [HR] = 1.38, 95% CI: 1.12-1.64; P < 0.00001) and high-carb low-fat diets (HR = 0.79, 95% CI: 0.55-1.04; P < 0.00001) improved IIEF-5 scores. Combined diet and exercise interventions decreased the likelihood of ED (OR = 0.49, 95% CI: 0.28-0.85; P = 0.01) and increased the IIEF-5 score (OR = 3.40, 95% CI: 1.69-5.11; P < 0.0001). Diets abundant in fruits and vegetables (OR = 0.97, 95% CI: 0.96-0.98; P < 0.00001) and nuts (OR = 0.54, 95% CI: 0.37-0.80; P = 0.002) were also correlated with lower ED risk. Our meta-analysis underscores a strong dietary-ED association, suggesting that low-fat/Mediterranean diets rich in produce and nuts could benefit ED management.

Aim To study the therapeutic effect of Balanophora polysaccharide(BPS)on gastric ulcer(GU)induced by acetic acid in rats and to investigateits mechanisms. Methods Sixty male SD rats were randomly divided into sham-operated group, GU model group, omeprazole positive group(3.6 mg·kg-1), and low, medium and high dose of BPS treatment groups(100, 200 and 400 mg·kg-1). The GU model group was prepared by acetic acid cautery method, and the morphology and pathological changes of ulcers were observed by visual observation combined with HE staining, and the ulcer area and inhibition rate were measured and calculated; superoxide dismutase(SOD)activity, malondialdehyde(MDA)content and glutathione peroxidase(GSH-PX)activity were measured by enzymatic assay; tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)content were detected by ELISA. The expression levels of epidermal growth factor(EGF)and epidermal growth factor receptor(EGFR)were measured by immunohistochemistry staining and Western blot. Results Compared with the sham-operated group, obvious ulcer damage was seen in the model group. Compared with the model group, the BPS-treated group showed a significant reduction in ulcer area, an increase in SOD and GSH-PX activity and EGF and EGFR expression levels, and a significant decrease in MDA, TNF-α and IL-6 content. Conclusions BPS has a therapeutic effect on GU in rats, and its mechanism may be related to the inhibition of oxidative stress, suppression of inflammatory stimuli and promotion of regenerative repair of gastric mucosa.

Through the comprehensive and systematic research of domestic and overseas literature and information, we studied ancient original records on Aconiti Kusnezoffii Radix and its toxicity, analyzed related adverse cases and the animal toxicity experiments in recent years, then systematically analyzed the safety of Aconitum and its preparations, and finally we summarized the clinical characteristics and potential risk factors related to the safety of Aconitum. A report on adverse events of Aconitum in 76 patients with myocardial damage and renal damage accounting for 53.9% and 42.1% respectively, indicated that the safety problems of Aconitum may be related to heart toxicity and liver-kidney toxicity. Aconitum had complex compositions, and based on the animal experiments, Aconitum decoction had the highest toxicity at 2 h, and it reduced significantly at 4 h, which showed that the toxic components mainly depend on the hydrolysis or the decomposition degree of diester diterpenoid alkaloids. According to the toxicity study, Aconitum toxicity might occur in cardiovascular system, nervous system, kidney, embryo, reproductive system, and it was contraindicated in pregnant women. So far, specific antidote for aconitine poisoning is still a blank. The key for treatment is to correct arrhythmia timely and effectively, maintain stable vital signs, and meanwhile, give gastric lavage, intravenous fluid infusion and other therapies. So we suggest that the basic study for Aconitum toxicology should be strengthened, and the pharmacology and mechanism of toxicity, as well as the mechanism of processing for raising efficiency and reducing toxicity, should be further clarified to determine the quantity-effect relationship and eliminate safety hazards in using Aconitum.

Objective To explore the infection status and clinical characteristics of healthcare-associated infection (HAD in patients initially diagnosed with multiple myeloma(MM) during the induction period.Methods Clinical data of 116 patients diagnosed with MM and initially treated with PAD(bortezomib + adriamycin + dexamethasone)or PDD(bortezomib + liposome doxorubicin + dexamethasone) regimen in a hospital were collected,infection rates and clinical characteristics of patients during the induction therapy period were analyzed statistically.Results Among 116 patients,69 received PAD regimen,and 47 received PDD regimen,infection rates in two groups were 79.7％ and 89.4％ respectively;73 patients received subcutaneous injection of bortezomib,43 received intravenous injection of bortezomib,infection rates in subcutaneous injection group and intravenous injection group were 78.1％ and 93.0％ respectively,difference was statistically significant between two groups(P＜0.05).During the induction period,HAI rate was 83.6％ (n =97),81 patients developed infection during the first course,infection status of 3 patients were not clear due to therapy outside the hospital,the actual infection rate was 71.7 ％ (81/113);infection rate during the second course was 56.6 ％ (64/113);a total of 98 patients completed three therapy courses,infection rate was 43.9％ (43/98);66 patients completed four therapy courses,infection rate was 28.8％ (19/66).With the increase of the therapy course,infection rate showed a downward trend.Infection sites from high to low were respiratory system,skin and mucosa,oral and gastrointestinal system,bloodstream,and urinary tract.Difference in constitute of clinical diagnosis between patients receiving and without receiving prophylactic antifungal agents during chemotherapy period was not statistically significant (P =0.063).Conclusion Infection rate is very high during induction period,the main infection site is respiratory system,clinicians and patients need to pay more attention to the prevention and treatment of respiratory system infection.

OBJECTIVETo investigate serum adiponectin level in patients with Alzheimer's disease (AD) and its correlation with the patients' cognitive function.

METHODSThis case-control study was conducted in 90 patients with a highly probable diagnosis ofAD, who were divided into mild, moderate and severe group saccording to the MMSE score. Ninety healthy subjects matched for age and gender with the AD patients were selected as the control group. The serum levels ofadiponectin in the participants were detected using enzyme-linked immunosorbent assay.

RESULTSSerum adiponectin level was significantly lower in the AD group than in the control group (P<0.05). Of the 3 subgroups of the AD patients, the moderate and severe AD groups showed significantly lower serum adiponectin level sthan the control group (P<0.05), but the difference in adiponectin levels was not significant between the mild AD group and the control group (P>0.05); serum adiponectin levels also differed significantly among the 3 subgroups of AD patients (P<0.05). Serum adiponectin level was positively correlated with the MMSE score in the AD patients (r=0.683, P<0.001).

CONCLUSIONSerum adiponectin levels are reduced in AD patients and associated with the degree of cognitive impairment.

OBJECTIVEThis study aimed to explore the scene-trait coping style of military rescuers in Wenchuan earthquake in an effort to provide scientific evidences for mental intervention program for Chinese military personnel.

METHODSBy cluster sampling, a total of 151 military rescuers and 331 control servicemen were administered the military personnel scene-trait coping style scale (MPSTCSS).

RESULTSAll active coping factor scores, and passive coping factor scores of affection, health and economy in the rescuer group were significantly higher than those in control group (P < 0.05). The 21-above age subgroup, the 3-year plus service subgroup, and the officer subgroup had significantly higher active coping factor scores on military tasks, military experience and personal development than those of the 21-below age subgroup, 3-year minus service subgroup and the soldier subgroup, respectively (P < 0.05 or P < 0.01).

CONCLUSIONThe earthquake relief servicemen can cope with stressful situations better than control group by taking active coping style. The officers, servicemen older than 21 years, and servicemen with more service duration than 3 years could usually take active coping style.

This study aimed to determine and quantitate the mammographic and sonographic characteristics in 13 cases of solid neuroendocrine breast carcinoma (NEBC) and to analyze the association of radiological findings with the clinical and histopathologic findings. The clinical data and imaging findings of 13 female patients with histologically confirmed solid NEBC were reviewed. Imaging data were evaluated by two radiologists for a consensual diagnosis. All patients presented with one palpable mass; only 1 experienced occasional breast pain, and 5 complained of fluid discharge. In 7 patients, the masses were firm and mobile. Regional lymph node metastasis was noted in only 1 patient. For the 10 patients who underwent mammography, 6 had a mass, 1 had clustered small nodules with clustered punctuate microcalcifications, 2 had asymmetric focal density, and 1 had solitary punctuate calcification. Most of the masses had irregular shape with indistinct or microlobulated margins. For the 9 patients who underwent ultrasonography (US), 9 masses were depicted, all of which were hypoechoic, mostly with irregular shape and without acoustic phenomena. Different types of acoustic phenomena were also identified. One patient had developed distant metastases during follow-up. NEBC has a variety of presentations, but it is mostly observed on mammograms as a dense, irregular mass with indistinct or microlobulated margins. Sonographically, it typically presents as an irregular, heterogeneously hypoechoic mass with normal sound transmission. Histories of nipple discharge and calcification observed using imaging are not rare.

BACKGROUNDIn 2003, China's National Free Antiretroviral Treatment Program (NFATP) was initiated as a pilot, which covered only 100 HIV/AIDS patients. By 2011, the pilot had evolved into a nationwide program and had provided free treatment for over 150 000 patients. The objective of this study was to report and evaluate the progress of China's free antiretroviral treatment program.

METHODSThe NFATP Database was systematically reviewed and a total of 150 692 HIV/AIDS patients were included in this study. Program progress indicators including the number of treated HIV/AIDS patients, follow-up visit rate, CD4 test rate, and viral load test rate were summarized and examined over a calendar year to evaluate the progress of NFATP quantitatively and qualitatively.

RESULTSBy the end of 2011, a total of 150 692 HIV/AIDS patients had been treated through the NFATP and 122 613 of them were still on treatment. Of all patients, about 72% were enrolled during the past four years. The dominant transmission route was blood related in the early phase of the NFATP, but gradually changed to sexual contact. Besides quantitative improvements, progress indicators also demonstrated significant qualitative improvements that the program had made during the past 9 years.

CONCLUSIONSGreat achievement has been made by China's NFATP. China's experience indicates the importance of a comprehensive response to the success of its treatment program. However, to ensure the quality and sustainability of treatment in the long term, more attention and resources should be paid towards program management.
